Heat waves are getting hotter and becoming more frequent because of rising rates of air pollution, putting children’s health at risk, a wide-ranging new report finds.

An article in the New England Journal of Medicine reviews current research to take a sweeping inventory of how air pollution and climate change interact to adversely affect people’s health, especially that of kids. It examined the link between fossil fuel emissions and a variety of consequences of climate change – including extreme weather events; wildfires; vector-borne illnesses such as malaria, Zika, and Lyme disease; and heat waves, a topic at the forefront of many people’s minds.

This month, for example, record-high temperatures have been reported across the United States, affecting more than 100 million people and touching locations from the Gulf Coast to the Great Lakes, the Southwest, the mid-Atlantic, and the Midwest.

In Texas, Austin has already experienced an 8-day streak of temperatures above the 100° F mark in June, according to the Austin American-Statesman.

These patterns are an important reality to note, said Frederica Perera, DrPH, PhD, the article’s lead author. “My concern is that the threats are rising as temperature is rising,” Dr. Perera, a professor at Columbia University’s Mailman School of Public Health, New York, told KHN. “Temperatures are rising because greenhouse gas emissions are rising, and that’s a great concern for everyone’s health – but especially the most vulnerable.”

Children fit into this category, wrote Dr. Perera and her coauthor, Kari Nadeau, MD, PhD, Naddisy Foundation Endowed Professor of Medicine and Pediatrics at Stanford (Calif.) University, because their ability to regulate temperature, known as thermoregulation, is not fully developed.

They are also more susceptible to heat-related stress because they’re smaller and need to drink and eat more frequently to stay healthy, said Dr. Perera. But because “young children are dependent on parents to provide, sometimes their needs go ignored,” she said.

The authors noted that heat-related illness is “a leading and increasing cause of death and illness among student athletes” in the United States. In addition, they cited studies suggesting that “the heat associated with climate change” takes a toll on the mental health of children and adolescents, as well as their ability to learn.

The review article pointed to previous research. that associated in utero exposure to heat waves with “increased risks of preterm birth or low birth weight; hyperthermia and death among infants; and heat stress, kidney disease, and other illnesses” among kids.

“Being pregnant is very physiologically demanding in itself, and then heat places additional stress on a pregnant woman,” said Dr. Robert Dubrow, a professor of epidemiology at Yale’s School of Public Health, New Haven, Conn., who was not associated with either study. “And the fetus can experience heat stress as well, which could result in adverse birth outcomes.”

And these heat-related risks are across-the-board greater for “low-income communities and communities of color,” wrote the authors of the new article.

Carbon dioxide emissions from burning fossil fuels have risen sharply in the past 70 years, according to the article. “Modeling indicates that some heat waves would be extraordinarily unlikely to occur in the absence of climate change,” it says.

The authors briefly outline solutions that they describe as “climate and environmental strategies” that “should also be seen as essential public health policy.” Beyond big-picture efforts to mitigate fossil fuel and greenhouse gas emissions, they offered various ways to protect children – steps they term “adaptation measures” – which included providing clean water to children and families facing drought or water contamination and creating shaded areas where children play, live, and go to school.

Separately, Austin-based research highlighted why this step could be meaningful.

Researchers tracked the physical activity levels and location of students ages 8 to 10 during recess at three elementary schools in 2019. They compared children’s activity at recess during two weeks in September, the hottest full month during the school year, to a cooler week in November. “We wanted to understand the impact of outdoor temperatures on children’s play in schoolyard environments,” said Dr. Kevin Lanza, the study’s lead investigator, to inform the design of “future school-based interventions for physical activity in the face of climate change.”

During the hotter periods, he said, “children engaged in less physical activity and sought shade.”

As temperatures continue to rise, he said, schools must be flexible in making sure students are getting the daily exercise they need. “Schools should consider adding shade, either by planting trees or installing artificial structures that cover spaces intended for physical activity,” said Dr. Lanza, an assistant professor at UTHealth School of Public Health, Austin, Tex. He also noted that school policies could be updated so that recesses are scheduled during cooler times of the day and moved inside during periods of extreme heat.

But the overall need to protect kids from scorching weather patterns requires action beyond such steps, Dr. Perera said, and more climate and clean air policies must be enacted.

“Governments have the responsibility to protect the population and especially those most vulnerable, which especially includes children,” Dr. Perera said. “Action must be done immediately because we’re absolutely heading in the wrong direction.”

MADRID – During the International Scientific Symposium “New Frontiers in Scientific Research” that recently took place in Barcelona, specialists analyzed the role of the very-low-calorie ketogenic diet. This analysis was in relation to three comorbidities that have a higher incidence among overweight and obese patients: polycystic ovary syndrome, nonalcoholic fatty liver disease, and type 2 diabetes. The experts’ aim? To analyze and update the latest evidence on the benefits of this dietary choice.

Polycystic ovary syndrome

Alessandra Gambineri, MD, PhD, associate professor at the department of medicine and surgery (DIMEC) at the University of Bologna, Italy, addressed the link between obesity and polycystic ovary syndrome, which she described as a chronic disease that affects about 10% of women of childbearing age and that presents diverse phenotypes with different characteristics.

“The pathophysiology of this syndrome is characterized by the interaction of three factors: androgen excess, adipose tissue dysfunction, and insulin resistance. These factors interact with each other and are expressed differently in each phenotype,” said Dr. Gambineri.

She indicated that adipose tissue dysfunction is central to this pathology. This centrality results from its association with secretions, such as free fatty acids, proinflammatory cytokines, certain adipokines that promote insulin resistance, glucocorticosteroids, androgens, and oxidative stress.

“Similarly, the oxidative stress that characterizes this syndrome is increasingly present in obese individuals,” said Dr. Gambineri. “This oxidative stress also produces ovary hypotoxicity that aggravates ovulatory function. In this context, the very-low-calorie ketogenic diet can be useful in several ways: weight reduction; promoting the loss of mainly visceral/abdominal fat; decreasing lipotoxicity; and improving inflammation, hyperinsulinemia, and insulin resistance.”

This was the path followed to carry out a study that aimed to analyze the effects of the very-low-calorie ketogenic diet on manifestations of polycystic ovary syndrome in the obesity phenotype. Dr. Gambineri presented its results.

“The objective was to compare the effects of a very-low-calorie ketogenic diet and the standard low-calorie (hypocaloric) diet as a control group,” she said. “The effects studied include body weight, insulin resistance, menstrual cycle, ovulation, ovarian morphology, and hyperandrogenism in a population of 30 obese women with polycystic ovary syndrome and insulin resistance.”

Study participants had a diagnosis of polycystic ovary syndrome as defined by the National Institutes of Health criteria and were aged 18-45 years. These women were randomly assigned to two groups of equal size: experimental (very-low-calorie ketogenic diet) and control (hypocaloric diet). “The women assigned to the experimental group followed the ketogenic stage for eight weeks and then moved to the second, low-calorie diet phase for an additional eight weeks, while those in the control group (hypocaloric diet) followed the low-calorie diet for all 16 weeks.”

The primary outcomes were changes in weight and body composition, specifically fat mass and lean mass, measured by bioimpedance. “The changes observed in the following aspects were considered secondary outcomes: abdominal fat distribution, metabolic parameters, ovulation, ovarian morphology, hirsutism, hyperandrogenism, psychological well-being, and psychological distress,” said Dr. Gambineri. “Any reduction in the ovarian stroma, the area where androgens are synthesized, was also analyzed.”

The study authors found that although BMI decreased in both groups, this reduction was greater in the group that followed the very-low-calorie ketogenic diet. Significant weight loss was observed in both groups, 12.4 kg versus 4.7 kg. Significant differences were also observed in waist circumference (−8.1% in the experimental group vs. −2.2% in the control group), fat mass (−15.1% vs. −8.5%), and free testosterone (−30.3% vs. +10.6%). Only the experimental group saw a reduction in insulin.

“A key point regarding hyperandrogenism, especially regarding what’s referred to as free testosterone, there was only a significant reduction in the very-low-calorie ketogenic diet group,” said Dr. Gambineri. “This reduction was especially evident in the first part of the study, coinciding with the ketogenic period. The reason for this effect lies in the significant increase in the concentration of sex hormone-binding globulins, SHB6. Said globulins bind to the testosterone present in female blood, producing a reduction in free testosterone, a very important effect considering that this syndrome is an androgenic disorder. Furthermore, current treatments for polycystic ovary syndrome do not reduce free testosterone as much as this dietary approach does.”

For the specialist, among all these positive effects in these patients, perhaps most important is the notable improvement that occurs in ovulation. “At the beginning of the study, only 38.5% of the participants in the experimental group and 14.3% of those in the control group had ovulatory cycles. After the intervention, 84.6% managed to ovulate, compared to 35.7% who achieved this goal in the other group.”

Dr. Gambineri suggested that this method is “valid for reducing fat mass and rapidly improving hyperandrogenism and ovulatory dysfunction in women with obesity and polycystic ovary syndrome.”
 

Reversing type 2 diabetes?

Daniela Sofrà, MD, an endocrinologist specializing in diabetology at La Source Clinic, Lausanne, Switzerland, reviewed the current evidence on the role of the very-low-calorie ketogenic diet in the management of type 2 diabetes.

“It’s time to rethink diabetes treatment and focus efforts on managing obesity as an associated factor,” she said. “One of the hypotheses being examined in this regard is the twin cycle, which postulates that type 2 diabetes is the result of excess fat in the liver. This in turn is associated with insulin resistance with pancreas dysfunction.”

Dr. Sofrà added that there is a study documenting for the first time the reversibility of the morphology of the diabetic pancreas after caloric restriction with the very-low-calorie ketogenic diet. “The reason for this effect is the use of visceral and intrahepatic fat, which can lead to the remission of the clinical manifestation of type 2 diabetes, understanding as such the definition made by the American Diabetes Association: glycosylated hemoglobin < 6.5% without pharmacological therapy.”

Specifically, the results of this research showed that after following the very-low-calorie ketogenic diet and achieving a 15% weight loss (mean weight loss of the participants), liver glucose levels returned to normal levels within 7 days. Beta cell function returned to near normal within 8 weeks.

“Subsequent studies have shown the durability of remission of type 2 diabetes, thanks to the reactivation of the insulin-secreting function of beta cells that had become dedifferentiated in the face of chronic nutrient excess. Specifically, 6 out of 10 patients maintained glycosylated hemoglobin < 6% after 6 months without the need for pharmacological therapy,” Dr. Sofrà added.

Likewise, she highlighted that the probability of achieving remission is mainly determined by the duration of the disease. “The years with diabetes are one of the main predictors of the response that the patient will have with this dietary intervention. Studies have shown that remission is possible in patients with diabetes for less than 6 years, although there are other projects that indicate that it can be achieved with up to 10 years’ duration.”

Based on these data, Dr. Sofrà emphasized the pleiotropic effects of the very-low-calorie ketogenic diet on glycemic control, favoring the possible remission of diabetes or the reduction of drugs, as well as the reduction of the HOMA-IR index (insulin resistance) and waist circumference in people with type 2 diabetes.
 

Nonalcoholic fatty liver disease

The third comorbidity of obesity that may benefit from the very-low-calorie ketogenic diet is hepatic steatosis, or nonalcoholic fatty liver disease, said Hardy Walle, MD, an internal medicine specialist and director/founder of the Bodymed center, Kirkel, Germany, and one of the authors of this research.

“Recent research shows that ectopic fat and nonalcoholic fatty liver disease could be considered a cause, or at least one of the causes, of most of the diseases that affect the population as a consequence of overweight and obesity,” said Dr. Walle. “Some authors have stated that without fatty liver, there is no type 2 diabetes.”

Dr. Walle pointed out that between 30% and 40% of the adult population has nonalcoholic fatty liver disease, a percentage that increases considerably in people with obesity, reaching 70% prevalence and increasing, in the case of type 2 diabetes, to almost 90%. “Even normal weight does not rule out fatty liver; in fact, about 15% of people with nonalcoholic fatty liver disease are not overweight.”

In a setting where there are no approved drugs for the treatment of fatty liver (the current standard approach focuses on lifestyle interventions), a short-term hypocaloric diet (or liver fasting) is considered an effective method for management of this pathology. This principle was demonstrated by a study by the Saarland University, Saarbrücken, Germany, that Dr. Walle used to illustrate this statement.

“The participants (60 patients with hepatic steatosis) followed a hypocaloric diet (less than 1,000 kcal/day) for 14 days with a formula rich in protein and fiber specially developed for the treatment of nonalcoholic fatty liver disease. A fibroscan was then performed with controlled attenuation parameter measurement to quantify fatty liver disease. The results showed not only a significant improvement in nonalcoholic fatty liver disease parameters but also a marked improvement in all relevant metabolic parameters (serum lipids, liver enzymes),” explained Dr. Walle.

“This evidence leads us to affirm that the concept of hepatic fasting (by means of a hypocaloric diet) marks a point of reference for a future treatment approach for nonalcoholic fatty liver disease,” he concluded.

The study that Dr. Gambineri presented was carried out with the collaboration of the Pronokal Group (Nestlé Health Science). Dr. Gambineri, Dr. Sofrà, and Dr. Walle disclosed no relevant financial relationships.

“This evidence leads us to affirm that the concept of hepatic fasting (by means of a hypocaloric diet) marks a point of reference for a future treatment approach for nonalcoholic fatty liver disease,” he concluded.

MADRID – During the International Scientific Symposium “New Frontiers in Scientific Research” that recently took place in Barcelona, specialists analyzed the role of the very-low-calorie ketogenic diet. This analysis was in relation to three comorbidities that have a higher incidence among overweight and obese patients: polycystic ovary syndrome, nonalcoholic fatty liver disease, and type 2 diabetes. The experts’ aim? To analyze and update the latest evidence on the benefits of this dietary choice.

Polycystic ovary syndrome

Alessandra Gambineri, MD, PhD, associate professor at the department of medicine and surgery (DIMEC) at the University of Bologna, Italy, addressed the link between obesity and polycystic ovary syndrome, which she described as a chronic disease that affects about 10% of women of childbearing age and that presents diverse phenotypes with different characteristics.

“The pathophysiology of this syndrome is characterized by the interaction of three factors: androgen excess, adipose tissue dysfunction, and insulin resistance. These factors interact with each other and are expressed differently in each phenotype,” said Dr. Gambineri.

She indicated that adipose tissue dysfunction is central to this pathology. This centrality results from its association with secretions, such as free fatty acids, proinflammatory cytokines, certain adipokines that promote insulin resistance, glucocorticosteroids, androgens, and oxidative stress.

“Similarly, the oxidative stress that characterizes this syndrome is increasingly present in obese individuals,” said Dr. Gambineri. “This oxidative stress also produces ovary hypotoxicity that aggravates ovulatory function. In this context, the very-low-calorie ketogenic diet can be useful in several ways: weight reduction; promoting the loss of mainly visceral/abdominal fat; decreasing lipotoxicity; and improving inflammation, hyperinsulinemia, and insulin resistance.”

This was the path followed to carry out a study that aimed to analyze the effects of the very-low-calorie ketogenic diet on manifestations of polycystic ovary syndrome in the obesity phenotype. Dr. Gambineri presented its results.

“The objective was to compare the effects of a very-low-calorie ketogenic diet and the standard low-calorie (hypocaloric) diet as a control group,” she said. “The effects studied include body weight, insulin resistance, menstrual cycle, ovulation, ovarian morphology, and hyperandrogenism in a population of 30 obese women with polycystic ovary syndrome and insulin resistance.”

Study participants had a diagnosis of polycystic ovary syndrome as defined by the National Institutes of Health criteria and were aged 18-45 years. These women were randomly assigned to two groups of equal size: experimental (very-low-calorie ketogenic diet) and control (hypocaloric diet). “The women assigned to the experimental group followed the ketogenic stage for eight weeks and then moved to the second, low-calorie diet phase for an additional eight weeks, while those in the control group (hypocaloric diet) followed the low-calorie diet for all 16 weeks.”

The primary outcomes were changes in weight and body composition, specifically fat mass and lean mass, measured by bioimpedance. “The changes observed in the following aspects were considered secondary outcomes: abdominal fat distribution, metabolic parameters, ovulation, ovarian morphology, hirsutism, hyperandrogenism, psychological well-being, and psychological distress,” said Dr. Gambineri. “Any reduction in the ovarian stroma, the area where androgens are synthesized, was also analyzed.”

The study authors found that although BMI decreased in both groups, this reduction was greater in the group that followed the very-low-calorie ketogenic diet. Significant weight loss was observed in both groups, 12.4 kg versus 4.7 kg. Significant differences were also observed in waist circumference (−8.1% in the experimental group vs. −2.2% in the control group), fat mass (−15.1% vs. −8.5%), and free testosterone (−30.3% vs. +10.6%). Only the experimental group saw a reduction in insulin.

“A key point regarding hyperandrogenism, especially regarding what’s referred to as free testosterone, there was only a significant reduction in the very-low-calorie ketogenic diet group,” said Dr. Gambineri. “This reduction was especially evident in the first part of the study, coinciding with the ketogenic period. The reason for this effect lies in the significant increase in the concentration of sex hormone-binding globulins, SHB6. Said globulins bind to the testosterone present in female blood, producing a reduction in free testosterone, a very important effect considering that this syndrome is an androgenic disorder. Furthermore, current treatments for polycystic ovary syndrome do not reduce free testosterone as much as this dietary approach does.”

For the specialist, among all these positive effects in these patients, perhaps most important is the notable improvement that occurs in ovulation. “At the beginning of the study, only 38.5% of the participants in the experimental group and 14.3% of those in the control group had ovulatory cycles. After the intervention, 84.6% managed to ovulate, compared to 35.7% who achieved this goal in the other group.”

Dr. Gambineri suggested that this method is “valid for reducing fat mass and rapidly improving hyperandrogenism and ovulatory dysfunction in women with obesity and polycystic ovary syndrome.”
 

Reversing type 2 diabetes?

Daniela Sofrà, MD, an endocrinologist specializing in diabetology at La Source Clinic, Lausanne, Switzerland, reviewed the current evidence on the role of the very-low-calorie ketogenic diet in the management of type 2 diabetes.

“It’s time to rethink diabetes treatment and focus efforts on managing obesity as an associated factor,” she said. “One of the hypotheses being examined in this regard is the twin cycle, which postulates that type 2 diabetes is the result of excess fat in the liver. This in turn is associated with insulin resistance with pancreas dysfunction.”

Dr. Sofrà added that there is a study documenting for the first time the reversibility of the morphology of the diabetic pancreas after caloric restriction with the very-low-calorie ketogenic diet. “The reason for this effect is the use of visceral and intrahepatic fat, which can lead to the remission of the clinical manifestation of type 2 diabetes, understanding as such the definition made by the American Diabetes Association: glycosylated hemoglobin < 6.5% without pharmacological therapy.”

Specifically, the results of this research showed that after following the very-low-calorie ketogenic diet and achieving a 15% weight loss (mean weight loss of the participants), liver glucose levels returned to normal levels within 7 days. Beta cell function returned to near normal within 8 weeks.

“Subsequent studies have shown the durability of remission of type 2 diabetes, thanks to the reactivation of the insulin-secreting function of beta cells that had become dedifferentiated in the face of chronic nutrient excess. Specifically, 6 out of 10 patients maintained glycosylated hemoglobin < 6% after 6 months without the need for pharmacological therapy,” Dr. Sofrà added.

Likewise, she highlighted that the probability of achieving remission is mainly determined by the duration of the disease. “The years with diabetes are one of the main predictors of the response that the patient will have with this dietary intervention. Studies have shown that remission is possible in patients with diabetes for less than 6 years, although there are other projects that indicate that it can be achieved with up to 10 years’ duration.”

Based on these data, Dr. Sofrà emphasized the pleiotropic effects of the very-low-calorie ketogenic diet on glycemic control, favoring the possible remission of diabetes or the reduction of drugs, as well as the reduction of the HOMA-IR index (insulin resistance) and waist circumference in people with type 2 diabetes.
 

Nonalcoholic fatty liver disease

The third comorbidity of obesity that may benefit from the very-low-calorie ketogenic diet is hepatic steatosis, or nonalcoholic fatty liver disease, said Hardy Walle, MD, an internal medicine specialist and director/founder of the Bodymed center, Kirkel, Germany, and one of the authors of this research.

“Recent research shows that ectopic fat and nonalcoholic fatty liver disease could be considered a cause, or at least one of the causes, of most of the diseases that affect the population as a consequence of overweight and obesity,” said Dr. Walle. “Some authors have stated that without fatty liver, there is no type 2 diabetes.”

Dr. Walle pointed out that between 30% and 40% of the adult population has nonalcoholic fatty liver disease, a percentage that increases considerably in people with obesity, reaching 70% prevalence and increasing, in the case of type 2 diabetes, to almost 90%. “Even normal weight does not rule out fatty liver; in fact, about 15% of people with nonalcoholic fatty liver disease are not overweight.”

In a setting where there are no approved drugs for the treatment of fatty liver (the current standard approach focuses on lifestyle interventions), a short-term hypocaloric diet (or liver fasting) is considered an effective method for management of this pathology. This principle was demonstrated by a study by the Saarland University, Saarbrücken, Germany, that Dr. Walle used to illustrate this statement.

“The participants (60 patients with hepatic steatosis) followed a hypocaloric diet (less than 1,000 kcal/day) for 14 days with a formula rich in protein and fiber specially developed for the treatment of nonalcoholic fatty liver disease. A fibroscan was then performed with controlled attenuation parameter measurement to quantify fatty liver disease. The results showed not only a significant improvement in nonalcoholic fatty liver disease parameters but also a marked improvement in all relevant metabolic parameters (serum lipids, liver enzymes),” explained Dr. Walle.

“This evidence leads us to affirm that the concept of hepatic fasting (by means of a hypocaloric diet) marks a point of reference for a future treatment approach for nonalcoholic fatty liver disease,” he concluded.

The study that Dr. Gambineri presented was carried out with the collaboration of the Pronokal Group (Nestlé Health Science). Dr. Gambineri, Dr. Sofrà, and Dr. Walle disclosed no relevant financial relationships.

CHICAGO – Health insurance should cover treatment for infertility caused by gender-affirming medical interventions, the American Medical Association said June 13 at its House of Delegates meeting.

Speaking on behalf of the Medical Student Section, Justin Magrath, of Louisiana, said, “We as a section feel that these interventions should be considered as additional causes of iatrogenic infertility and be covered by insurance.”

Iatrogenic infertility is infertility caused by surgery, radiotherapy, chemotherapy, or other medically necessary treatment. The AMA voted June 13 to support including the phrase, “impaired fertility as a consequence of gender-affirming hormone therapy and gender-affirming surgery,” in that definition.

The AMA also supports access to fertility preservation services for people who undergo those treatments.

“I’ve had many friends who went through transitions and gender-affirming care and had no idea that these options were available and others who did know they were available but they were so expensive that they couldn’t access them,” said emergency medicine resident Sophia Spadafore, MD, delegate for the Resident and Fellow Section. “So while people might be able to access gender-affirming care, sometimes they have to make the decision between future fertility and having children and accessing this kind of lifesaving care that we support.”

The AMA already had policies that support insurance coverage of treatments for gender dysphoria and the right to seek fertility preservation services for people who undergo gender-affirming hormone therapy or surgery, but until this week, it had not addressed insurance coverage for preserving fertility in those cases.

“The transgender population already faces many barriers to care, such as provider discrimination, legal concerns, financial burden, and emotional cost,” Mr. Magrath said during a reference committee hearing on June 11. “We as a section ask our organization to continue to serve as an ally, providing equitable care for diverse populations and expanding coverage for medically necessary treatments.”

“I am a gender surgeon, so this is pretty important to me,” said Sean Figy, MD, of Nebraska, a delegate for the American Society for Reconstructive Microsurgery.

The original resolution included the words “medically necessary” when referring to gender-affirming treatments, and Dr. Figy expressed hesitancy about those words. An amendment removed them.

“I’ve seen that phrase weaponized against gender-nonconforming patients,” he said.

Ophthalmologist Charles Hickey, MD, of the Ohio delegation, spoke in favor of referral or of waiting to adopt the resolution.

“I think the different amendments being discussed here are evidence that this needs a more thorough and careful treatment than we can do at this point right now,” he said.

DENVER – Psychedelics such as psilocybin “truly have the potential to transform how we treat a number of neuropsychiatric diseases, including headaches,” a neuropharmacologist told colleagues at the annual meeting of the American Headache Society.

However, Bryan Roth, MD, PhD, professor of pharmacology at the University of North Carolina at Chapel Hill, also offered a major cautionary note: There have been no randomized, phase 3 trials of psychedelics, and he bluntly said that “I do not recommend the use of psychedelics for any medical condition.”

The potential disease-altering powers of psychedelics have received a tremendous amount of research and media attention over the past several years. A landmark randomized, double-blind study released in 2016 triggered much of the interest, Dr. Roth said, when it suggested that high-dose psilocybin significantly lowered levels of depressed mood/anxiety in patients with life-threatening cancer. At 6 months, 80% of patients who took the dose reported moderate or greater improvement in well-being/life satisfaction.

“You have the potential – unprecedented in psychiatry – that a single dose of a therapeutic agent may induce a rapid, robust, and sustained antidepressant action,” he said. Also of note: The “vast majority” of subjects say their encounter with a psychedelic was “one of the most meaningful experiences of their lives.”

Dr. Roth said his own research suggests that psychedelics cause a “huge increase” in the asynchronous firing of neurons. “Noise is being injected into the system and is interpreted by the brain or the mind, which always likes to make a story about what’s going on. The story it makes up is idiosyncratic to every person and memorable for reasons that are not understood.”

Now, Dr. Roth said, he and colleagues are working to “create drugs that have this potential remarkable therapeutic efficacy in psychiatric and neurologic disorders without the psychedelic effects.” A $27 million grant from the Defense Advanced Research Projects Agency is providing support for their efforts, he said.

For the moment, he said, there’s no way to know if “the psychedelic experience is essential to the therapeutic action of these drugs. But it’s a testable hypothesis.”

As he noted, a tiny 2010 study of 2-bromo-lysergic acid diethylamide (LSD), which doesn’t cause hallucinations, showed promise as a treatment for cluster headaches.

For now, Dr. Roth said, his lab is synthesizing and testing new compounds that interact with the crucial 5-HT2A receptor.
 

Additional research

In another presentation at the AHS annual meeting, neurologist Emmanuelle A. D. Schindler, MD, PhD, of Yale School of Medicine, highlighted her 2021 study of an exploratory double-blind, placebo-controlled, cross-over study of psilocybin versus placebo for migraine headache. A single oral dose of the drug, the researchers found, reduced headache frequency and pain over 2 weeks. The study is small, with just 10 subjects, and multiple exclusion criteria.

She also revealed preliminary findings from an ongoing randomized, double-blind, placebo-controlled study of psilocybin versus placebo in cluster headaches. In 14 subjects, a psilocybin pulse was linked to fewer cluster attacks over 3 weeks, although the effect wasn’t statistically significant. However, there was a statistically significant reduction over 8 weeks in patients with chronic headache.

Dr. Schindler noted that “with these early studies, we only looked out to 2 weeks for migraine, and we only looked out to 2 months for cluster.” There are multiple other limitations, she acknowledged. “We have to do a lot more research and consider safety as well.”

However, “there is a really unique capacity for lasting effects after limited dosing,” she added, and the studies do show reductions in headache burden “that do not correlate with acute psychedelic effects.”

Moving forward, Dr. Roth cautioned that while U.S. states are allowing the use of psychedelics for medical purposes, “we don’t know if they ultimately are therapeutic. And we have strong reason to believe that microdosing or chronic dosing of these compounds is ultimately going to be deleterious to the health of our patients.”

Dr. Roth did not provide disclosure information. Dr. Schindler discloses research funding (Ceruvia Lifesciences, Wallace Research Foundation, Clusterbusters, Department of Veterans Affairs), serves on advisory boards (Ceruvia Lifesciences, Clusterbusters), and has a patent.

Erythema annulare centrifugum

A thorough body examination failed to reveal any other rashes or lesions suggestive of a fungal infection. A blood count and urinalysis were within normal limits. She had no lymphadenopathy or hepatosplenomegaly. A potassium hydroxide analysis of skin scrapings was negative for fungal elements. Punch biopsy of the skin on the left arm revealed focal intermittent parakeratosis, mildly acanthotic and spongiotic epidermis, and a tight superficial perivascular chronic dermatitis consisting of lymphocytes and histiocytes (Figures). Given these findings, a diagnosis of erythema annulare centrifugum (EAC) was rendered.

EAC is a rare, reactive skin rash characterized by redness (erythema) and ring-shaped lesions (annulare) that slowly spread from the center (centrifugum). The lesions present with a characteristic trailing scale on the inner border of the erythematous ring. Lesions may be asymptomatic or mildly pruritic and commonly involve the trunk, buttocks, hips, and upper legs. It is important to note that its duration is highly variable, ranging from weeks to decades, with most cases persisting for 9 months. EAC typically affects young or middle-aged adults but can occur at any age.

Erythema marginatum is a rare skin rash commonly seen with acute rheumatic fever secondary to streptococcal infection. It presents as annular erythematous lesions on the trunk and proximal extremities that are exacerbated by heat. It is often associated with active carditis related to rheumatic fever. This self-limited rash usually resolves in 2-3 days. Our patient was asymptomatic without involvement of other organs.

Like EAC, granuloma annulare is a benign chronic skin condition that presents with ring-shaped lesions. Its etiology is unknown, and lesions may be asymptomatic or mildly pruritic. Localized granuloma annulare typically presents as reddish-brown papules or plaques on the fingers, hands, elbows, dorsal feet, or ankles. The distinguishing feature of granuloma annulare from other annular lesions is its absence of scale.

Urticaria multiforme is an allergic hypersensitivity reaction commonly linked to viral infections, medications, and immunizations. Clinical features include blanchable annular/polycyclic lesions with a central purplish or dusky hue. Diagnostic pearls include the presence of pruritus, dermatographism, and individual lesions that resolve within 24 hours, all of which were not found in our patient’s case.

Given these findings, a diagnosis of erythema annulare centrifugum (EAC) was rendered.

EAC is a rare, reactive skin rash characterized by redness (erythema) and ring-shaped lesions (annulare) that slowly spread from the center (centrifugum). The lesions present with a characteristic trailing scale on the inner border of the erythematous ring. Lesions may be asymptomatic or mildly pruritic and commonly involve the trunk, buttocks, hips, and upper legs. It is important to note that its duration is highly variable, ranging from weeks to decades, with most cases persisting for 9 months. EAC typically affects young or middle-aged adults but can occur at any age.

Erythema marginatum is a rare skin rash commonly seen with acute rheumatic fever secondary to streptococcal infection. It presents as annular erythematous lesions on the trunk and proximal extremities that are exacerbated by heat. It is often associated with active carditis related to rheumatic fever. This self-limited rash usually resolves in 2-3 days. Our patient was asymptomatic without involvement of other organs.

Like EAC, granuloma annulare is a benign chronic skin condition that presents with ring-shaped lesions. Its etiology is unknown, and lesions may be asymptomatic or mildly pruritic. Localized granuloma annulare typically presents as reddish-brown papules or plaques on the fingers, hands, elbows, dorsal feet, or ankles. The distinguishing feature of granuloma annulare from other annular lesions is its absence of scale.

Urticaria multiforme is an allergic hypersensitivity reaction commonly linked to viral infections, medications, and immunizations. Clinical features include blanchable annular/polycyclic lesions with a central purplish or dusky hue. Diagnostic pearls include the presence of pruritus, dermatographism, and individual lesions that resolve within 24 hours, all of which were not found in our patient’s case.

A recent series of columns on practice merger options generated a multitude of questions regarding merger, employment, and buyout agreements. The most common question was, “Do I really need to go to the trouble and expense of negotiating them?” If you have more than one physician in your group, you absolutely do need written contracts for a variety of reasons, but mostly to avoid conflicts later on. The proverbial “handshake agreement” is worthless in a major business dispute; everyone loses in such situations except the lawyers and accountants.

Mergers and buy-ins were covered at some length in my two previous columns. If the arrangement is to be one of employer and employees rather than a merger of equal partners, you will need an employment agreement to cover duties, requirements, expectations, and benefits. They define how each practitioner/employee will be paid, along with paid time off, health insurance, expense allowances, and malpractice coverage, among other basics. The more that is spelled out in the employment agreement, the fewer disagreements you are likely to have down the road.

Many employment contracts include a “termination without cause” clause, which benefits both the practice and the practitioners. It allows a practice to terminate a new associate if it feels a mistake has been made, even if he or she has done nothing wrong. On the other hand, the newcomer has the option to terminate if a better offer arises, their spouse hates the area, or for any other reason.

Buyouts should be addressed in advance as well. Several recent correspondents told me they didn’t see the necessity of writing a buyout agreement, because they plan to eventually sell their practice, rendering any buyout conditions moot. But what happens if an associate dies, becomes permanently disabled, or abruptly decides to leave the practice? If you haven’t prepared for such eventualities, you could find yourself receiving a demand from your ex-partner (or surviving spouse) for immediate payment of that partner’s portion of the practice’s value. And your valuation of the practice is likely to be severely at odds with the other party’s. Meanwhile, remaining partners must cover all the practice’s expenses and deal with an increased patient load.

A buyout agreement avoids these problems by planning for such eventualities in advance. You must agree on how a buyout amount will be valued. As I’ve said in previous columns, I strongly advise using a formula, not a fixed amount. If a buyout is based on 15- or 20-year-old reimbursements, the buyout will have no relationship to what the partners are currently being paid. Likewise, any buyout calculated at “appraised value” is a problem, because the buyout amount remains a mystery until an appraisal is performed. If the appraised value ends up being too high, the remaining owners may refuse to pay it. Have an actuary create a formula, so that a buyout figure can be calculated at any time. This area, especially, is where you need experienced, competent legal advice.

To avoid surprises, any buyout should require ample notice (6-12 months is common) to allow time to rearrange finances and recruit a new provider. Vesting schedules, similar to those used in retirement plans, are also popular. If a partner leaves before a prescribed time period has elapsed – say, 20 years – the buyout is proportionally reduced.

Buyouts can also be useful when dealing with noncompete agreements, which are notoriously difficult (and expensive) to enforce. One solution is a buyout penalty; a departing partner can compete with his or her former practice, but at the cost of a substantially reduced buyout. This permits competition, but discourages it, and compensates the targeted practice.

Buyouts are also a potential solution to some buy-in issues. A new associate entering an established practice may not be able to contribute assets equal to existing partners’ stakes and may lack the cash necessary to make up the difference. One alternative is to agree that any inequalities will be compensated at the other end in buyout value. Those partners contributing more assets will receive larger buyouts than those contributing less.

As I’ve said many times, these are not negotiations to undertake on your own. Enlist the aid of a consultant or attorney (or both) with ample medical practice experience.

COVID-19, caused by SARS-CoV-2, is more severe in individuals with underlying illnesses. Because complete social distancing might be more difficult in nursing homes and community living centers (CLCs), public health leaders and clinicians have been concerned about the epidemiology and disease course in nursing homes even before the COVID-19 pandemic.1-7 A report of a COVID-19 outbreak in a nursing home facility in King County, Washington, documented a 33.7% overall fatality rate for residents and 52.4% among the most critically ill.^4,5 The experience at King County, Washington, shows that proactive steps to identify, monitor, and apply preventive control measures is important for future outbreaks.⁵

Reverse transcriptase polymerase chain reaction (RT-PCR) testing produces a cycle threshold (CT) or cycle number (CN) that correlates with viral load and infectiousness. ^8-14 CT/CN represents the number of RT-PCR cycles required for the fluorescent signal to cross the detection threshold (exceed background level) and is inversely proportional to the viral load. Effectively, the higher the viral load, the lower the CT/ CN value (Figure 1). Tracking CT/CN values was not documented in the Washington nursing home outbreak. Reports of COVID- 19 testing in CLCs during outbreaks are sparse, and CT/CN values and demographic distribution of these veterans has not been reported.¹⁵ The CLC veteran population, with known higher vulnerability to infection and chronic diseases, is epidemiologically different from the general nursing home population.^15-18 To address these literature gaps, we present the first report of COVID- 19 testing with CT/CN value correlations in the high-risk veteran CLC population.

Methods

A retrospective review of all COVID-19 CT/CN testing at the Corporal Michael J. Crescenz Veterans Affairs Medical Center (VAMC) CLC in Philadelphia, Pennsylvania, from March 28, 2020, to April 24, 2020, was performed with a US Department of Veterans Affairs (VA) Veterans Health Information System Architecture VistA/FileMan search. Only veteran residents were included in this review. Data collected included initial and serial test results, CT/CN on positive test results, test dates, testing platform used, demographic information (age, self-reported ethnicity, and sex), and clinical follow-up information. Health records were reviewed retrospectively to identify death, the first day after diagnosis with no documented symptoms, or hospitalization status.

RT-PCR testing was performed with the Abbott RealTime SARS-CoV-2 assay on the Abbott m2000 platform and the Xpert Xpress SARS-CoV-2 assay on the Cepheid Infinity platform. The Xpert Xpress assay gave 2 CT values for the E and N2 targets on positive samples.¹⁹ For this assay to indicate a positive specimen, amplification by RT-PCR of the N2 target or both the N2 and E target is required. The Xpert Xpress assay results as presumptive positive if only the E target amplified. This assay counts a maximum of 45 cycles. The Abbott RealTime SARS-CoV-2 assay gave 1 CN derived from the RNA-dependent RNA polymerase and N targets on positive samples.20 The Abbott assay on the m2000 counts a maximum of 37 cycles. The CT/CN value is the number of cycles required by RT-PCR for the fluorescence signal to cross a threshold value exceeding background level.^19,20

Samples that are negative for COVID-19 by RT-PCR do not produce a CT/CN value. Although both instruments were used for RT-PCR, the precise CT/CN values are not interchangeable and CT/CN observations over time between the 2 instruments during the disease course would be based on CT/CN value movement (general upward or downward trend) rather than absolute CT/CN differences. Both assays have been approved by emergency use authorization as qualitative tests for the presence/absence of COVID-19. Although the CT/CN value is available to laboratory staff after test completion, the CT/CN value is not reported routinely in the patient health record. All veteran patients identified on the initial review from March 28, 2020, to April 24, 2020, had all serial COVID-19 testing recorded until November 10, 2020. The CN values at the limit of detection (LOD) for the Abbott m2000 platform from the initial validation study were reviewed for reference.²¹

Results

Of 80 patients, 25 (31%) were COVID-19 positive over the course of testing. The study population had a mean age of 73.5 years; 92% were aged > 60 years. The group was predominantly male (79 male vs 1 female). Among the 77 patients with a stated ethnicity, 39 (51%) were African American. In comparison, 43% of residents in Philadelphia County are African American (Table).^22,23 Additionally, a previously published total COVID-19 tested population by ethnicity at the same regional VAMC revealed 46.8% of tested veteran patients were African American. ²⁴ Three patients had no stated ethnicity. Among those who tested positive, 11 were African American patients, 12 were White patients, and 2 had no stated ethnicity. Four patients tested positive on their first test. The other 21 patients were positive on repeat testing. Interestingly, 6 patients had 1 initial negative test before a positive test, 6 patients had 2, 8 patients had 3, and 1 patient had 4 initial negative tests before a positive test result. Among the 25 positive patients, 22 were either positive within 10 days of the initial negative test result or initially positive (Figure 2). Three patients who tested positive after 10 days did so at 16, 20, and 21 days after the initial negative test result. Among the 25 positive patients, 23 had initial and serial testing from both the Abbott and Xpert Xpress assays. The remaining 2 positive patients had initial and serial testing from the Abbott assay exclusively.

Only positive COVID-19 results by RTPCR produced a CT/CN value. After disease resolution with a negative test, no CT/CN value was produced with the negative test result on either testing platform. Because repeat testing after the initial positive result took place no sooner than 10 days, we observed that the CT/CN value increased after the initial positive result until the disease resolved, and a negative result was obtained (eAppendix 1, available online at doi:10.12788/fp.0276). A t test comparing the initial CT/CN value to the value more than 10 days after the initial positive showed the CT/CN was statistically significantly higher (P < .05).

Prompt repeat testing after the initial test can show a decrease in the CT/CN value because of increasing viral load before the expected increase until disease resolution if the initial test caught the infection early. Twelve patients had a negative test result between 2 serial positive results. These negative test results occurred later, near the end of the disease course. Among the 12 patients with this positive-negativepositive CT/CN pattern, 7 were symptomatic and no longer had documented symptoms or hospitalization around the time of this positive-negative-positive pattern. Four of these individuals were asymptomatic during the entire infection course. One of the 12 patients with this pattern expired with the negative result occurring on day 27 of the disease in the context of rising CT/CN. One of these 12 patients only had a presumptive positive test result on the Cepheid because it detected only the E target with a CT value of 38.7. In 1 of the 12 patients, the negative test result occurred between 2 positive test results with CT/CN values < 20 (12.05 and 19.05 for the positive tests before and after the negative result, respectively). When the initial CT/CN values was separated based on ethnicity, the average CT/CN value for African Americans (23.3) was higher than for other ethnicities (19.9), although it did not reach statistical significance (P = .35).

Ten of the 25 patients testing positive were admitted to the hospital, including 1 admitted 15 days before diagnosis (patient 20) and 1 admitted 80 days after diagnosis (patient 7). Among these 10 patients, 6 were admitted to the intensive care unit, including patient 7. None of the patients were intubated. Three of the 10 admitted patients died (patients 7, 20, and 24). Patient 7 was a 79-year-old male with a history of dementia, cerebrovascular accident, hypertension, hyperlipidemia, and chronic kidney disease with symptoms of lethargy and refusal of oral intake when he was diagnosed with COVID-19. He was admitted 80 days after diagnosis for hyponatremia and acute renal failure, with death on day 87 recorded as complications from the earlier COVID-19 infection. Patient 20, an 89-year-old male with a history of dementia, chronic kidney disease, and hyperlipidemia, had been admitted with fever, cough, and leukocytosis 17 days before COVID-19 diagnosis. He continued to be symptomatic after diagnosis with development of hypotension, dehydration, and refusal of oral intake while on comfort measures/endof- life care and died 15 days after COVID- 19 infection diagnosis. Patient 24 was a 96-year-old male with history of heart failure, hypertension, coronary artery disease, prostate carcinoma, and dementia who developed a cough at the time of diagnosis; because of his underlying condition, he remained in the CLC on comfort care. His symptoms, including hypoxia, worsened until he died 7 days after diagnosis.

Among the 25 patients, 17 were symptomatic at the time of diagnosis; the 14 initially symptomatic patients who survived improved clinically and returned to baseline. Eight of the 25 patients were asymptomatic initially and 3 developed symptoms 2 to 5 days after diagnosis. Only 1 patient who remained asymptomatic was admitted for inability to adhere to quarantine at the CLC. Review of the health records of all surviving symptomatic patients showed symptom resolution with return to baseline that corresponds to an increasing CT/CN value. A 1-tailed t test comparing the initial CT/ CN at the time of diagnosis to the last CT/CN value for symptomatic patients who recovered revealed a statistically significant increase (P < .05). For the symptomatic, symptom resolution and hospital discharge took (if required) a mean 20 days (range, 7-46). Among those who were not hospitalized, symptoms resolved in 7 to 36 days (18 days). Among those requiring hospitalization at any time (excluding patients who died or were asymptomatic), symptom and hospitalization resolution took a mean 22 days (range, 10-46). Asymptomatic patients (patients 8, 10, 15, 16, and 25) also showed increasing CT/CN value during the infection course, although there was no correlation with the continued lack of symptoms.

During the initial validation of the Abbott m2000 instrument, an LOD study included concentrations of 1000, 500, 250, 100, 70, 60, and 50 virus copies/mL (eAppendix 2, available online at doi:10.12788/fp.0276).21 The average CN at 100 virus copies/mL—the manufacturer provided LOD in the instructions for use—was 25.74.20 At a concentration of one-half that (50 virus copies/mL), the average CN was 28.39.

Discussion

This is the first study in the English literature to track CT/CN values as part of serial testing of a veteran CLC. Widescale testing and repeat screening in the absence of symptoms of nursing home residents would identify those who are infected and allow providers to track viral load clearance.^9-14 CT/CN values, when serially tracked during the infection course, appear to increase with illness resolution, consistent with earlier reports that CT/CN correlates with viral load.^8-14 Serial CT/CN values that are high (> 25) and continue to increase with each test suggest progression toward disease resolution or viral RNA clearance.^8-14 After symptom resolution, patients can have a persistent low level of viral shedding (corresponding to a high CT/CN value).^10-14,25 Near the end of disease resolution, a negative serial RT-PCR sample test before a subsequent positive might be a promising clinical sign of near disease recovery. Once the viral load is low with a CT/CN significantly higher than 25, some specimens might result as negative but turn up positive on subsequent sampling with a high CT/CN value. This pattern, with attendant high CT/CN values for the positive results, are consistent with the known effect of viral load (ie, a low viral load correlates to a high CT/CN) and adequacy of specimen collection on CT/CN values^.25 If the patient’s viral load is low, the sample collected might have a viral load at or near the testing platform’s LOD.

For Abbott m2000, the manufacturer provided LOD is 100 virus copies/mL, although the instrument was able to detect virus concentrations below that level during the initial validation.²⁰ The actual LOD of the instrument at our institution is < 100 virus copies/mL. For the Cepheid Xpert Xpress SARS-CoV-2 assay, the manufacturer-provided LOD is 250 virus copies/mL.19 An LOD study including samples below the manufacturer-provided LOD was not part of the initial validation study for the Xpert Xpress assay. Nonetheless, the virus concentration of samples with very high CT values at or near the maximum CT value of 45 is expected to be at or near the platform’s actual LOD.

If the samples collected near the end of the patient’s disease course have viral loads near these low concentrations, the encouraging positive-negative-positive pattern with high CT/CN values might be a promising sign for viral clearance. On the other hand, a positive-negative-positive pattern in the setting of low CT/CN values before and after the negative test might indicate poor sampling for the negative specimen. The back-and-forth or positive-negative-positive pattern generally appears to indicate near resolution of the infection course, although clinical correlation is necessary to rule out inadequate sampling earlier in the disease course or prolonged viral RNA shedding.^9-14 In all of the surviving symptomatic patients who showed the positive-negative-positive pattern, this sign occurred around or after symptom resolution. It also is important to consider that in some patients, SARS-CoV-2 RNA might remain detectable with increasing CT/CN after symptom resolution, and samples from these patients might not result positive. Therefore, CT/CN values cannot be interpreted without considering the clinical picture.²⁵

Studies on infectiousness and virus culture from COVID-19 samples with CT/ CN correlation have shown that patients with high CT/CN at the end of their disease course might not be as infectious.^9-14,25 Because 1 patient had a presumptive positive result after the negative result, this study shows that this positive-negative-positive pattern could include presumptive positive results. Also, in the setting of a recent positive result on the same testing platform, a patient with this pattern is presumed to be positive for COVID-19 RNA because of scant viral material.

Taiwan’s public health response to the outbreak illustrates the ability to mitigate an outbreak throughout a society.²⁶ These actions could help blunt an outbreak within a civilian nursing home population.⁵ Mitigation within a veteran CLC population has been documented, but the study, which focused on mitigation, did not consider CT/CN values, demographic distribution, testing access of the studied population, or laboratory findings related to disease pathophysiology.¹⁵ A key ingredient in widescale, serial testing is the availability of a rapid turnaround from testing in-house that allowed identification within 24 hours instead of several days at a reference laboratory. ¹⁵ Rapid widescale testing would allow clinical teams to optimize the Triangle of Benefit of Widescale Timely Tests for CLC (Figure 3).¹⁵ Timely laboratory testing remains pivotal for CLC veteran residents to aid successful clinical triage and management. Reporting serial CT/CN values can provide additional information to clinicians about the disease course because CT/ CN correlates with viral load, which varies based on where the patient is in the disease course.^9-14 CT/CN values carry significant prognostic value, particularly with respect to intubation and mortality.⁸

Limitations

Important limitations to our study include the use of 2 separate RT-PCR platforms. Using different RT-PCR platforms is common in clinical laboratories trying to take advantage of the unique characteristics of different platforms—for example, turnaround time vs high throughput— to manage COVID-19 testing workflow.²⁵ However, the exact CT/CN values obtained from each platform might not translate to the other, and the general trend (CT/CN values are rising or falling across serial tests) rather than a single value could be useful for clinical correlation. Even when the same platform is used for the serial testing, CT/CN values can be affected by adequacy of specimen collection; therefore, clinical correlation and considering the trend in CT/CN values is necessary for interpretation.^10-14,25 Because of the known trend in viral dynamics, a positive specimen collected with a high CT/CN followed by a subsequent (within 2 days) positive specimen collected with a low CT/CN might be compatible with early detection of COVID- 19 infection in the appropriate clinical context. ^10-14 However, detection late in the infection course or even after the symptomatic disease resolved with prolonged viral shedding might show serial positive samples with increasing CT/CN values.^10-14

Patients with prolonged viral shedding might not be infectious.27 Because of the clinical correlation required for interpretation and the other factors that might affect CT/CN values, recommendations advise against using CT/CN values in clinical practice at this time, although these recommendations could change with future research.25 Serial CT/CN values have the potential, if appropriately correlated with the clinical picture, to provide useful information, such as whether the viral load of the sample is relatively high or low and increasing or decreasing.

Veterans, as a population, are more susceptible to poor health outcomes and morbidity compared with similar civilian counterparts.^2,14-16 Veteran CLC patients likely would experience worse outcomes with COVID-19, including more infections, expiration, and morbidity compared with similar general population nursing homes. Similar to what had been reported for the civilian population, a trend (high CT/CN values early in the disease course with repeat testing needed to detect all positives followed by lower CT/CN value to correlate with increased viral load and then increased CT/CN value as the infection resolved) also was observed in this veteran population.

It has been extensively documented that minority groups experience decreased health care access and worse health outcomes. ^28-30 Considering the critical medical supply shortages, including personal protective equipment, ventilators, and even testing supplies, there is the potential for a resource access disparity by ethnicity.^28-31 Because the VA does not depend on measures of wealth and privilege such as health insurance, there was no disparity noted in access to testing by race or ethnicity at the VAMC CLC. When considering the health outcome of viral load from the measured CT/CN value, the viral loads of African American patients and those of other ethnicities was not significantly different in this study.

Conclusions

This is the first study to bring up critical points including serial CT/CN value correlation in RT-PCR tests, demographic distributions demonstrating easy and equal access in a veteran nursing home to COVID-19 testing, and clinical laboratory signs related to disease pathophysiology. Unlike other populations who have undergone serial CT/CN monitoring, nursing homes represent a particularly vulnerable population who require measures to prevent the spread and mitigate outbreaks of COVID-19.^2,4,5 Test measurements obtained such as the CT/CN value during routine clinical care can provide useful information for public health, epidemiologic, or clinical purposes with appropriate correlation to clinical and other laboratory parameters. This study demonstrates early intervention of serial testing of an outbreak in a veterans nursing home with CT/CN value correlation.

COVID-19, caused by SARS-CoV-2, is more severe in individuals with underlying illnesses. Because complete social distancing might be more difficult in nursing homes and community living centers (CLCs), public health leaders and clinicians have been concerned about the epidemiology and disease course in nursing homes even before the COVID-19 pandemic.1-7 A report of a COVID-19 outbreak in a nursing home facility in King County, Washington, documented a 33.7% overall fatality rate for residents and 52.4% among the most critically ill.^4,5 The experience at King County, Washington, shows that proactive steps to identify, monitor, and apply preventive control measures is important for future outbreaks.⁵

Reverse transcriptase polymerase chain reaction (RT-PCR) testing produces a cycle threshold (CT) or cycle number (CN) that correlates with viral load and infectiousness. ^8-14 CT/CN represents the number of RT-PCR cycles required for the fluorescent signal to cross the detection threshold (exceed background level) and is inversely proportional to the viral load. Effectively, the higher the viral load, the lower the CT/ CN value (Figure 1). Tracking CT/CN values was not documented in the Washington nursing home outbreak. Reports of COVID- 19 testing in CLCs during outbreaks are sparse, and CT/CN values and demographic distribution of these veterans has not been reported.¹⁵ The CLC veteran population, with known higher vulnerability to infection and chronic diseases, is epidemiologically different from the general nursing home population.^15-18 To address these literature gaps, we present the first report of COVID- 19 testing with CT/CN value correlations in the high-risk veteran CLC population.

Methods

A retrospective review of all COVID-19 CT/CN testing at the Corporal Michael J. Crescenz Veterans Affairs Medical Center (VAMC) CLC in Philadelphia, Pennsylvania, from March 28, 2020, to April 24, 2020, was performed with a US Department of Veterans Affairs (VA) Veterans Health Information System Architecture VistA/FileMan search. Only veteran residents were included in this review. Data collected included initial and serial test results, CT/CN on positive test results, test dates, testing platform used, demographic information (age, self-reported ethnicity, and sex), and clinical follow-up information. Health records were reviewed retrospectively to identify death, the first day after diagnosis with no documented symptoms, or hospitalization status.

RT-PCR testing was performed with the Abbott RealTime SARS-CoV-2 assay on the Abbott m2000 platform and the Xpert Xpress SARS-CoV-2 assay on the Cepheid Infinity platform. The Xpert Xpress assay gave 2 CT values for the E and N2 targets on positive samples.¹⁹ For this assay to indicate a positive specimen, amplification by RT-PCR of the N2 target or both the N2 and E target is required. The Xpert Xpress assay results as presumptive positive if only the E target amplified. This assay counts a maximum of 45 cycles. The Abbott RealTime SARS-CoV-2 assay gave 1 CN derived from the RNA-dependent RNA polymerase and N targets on positive samples.20 The Abbott assay on the m2000 counts a maximum of 37 cycles. The CT/CN value is the number of cycles required by RT-PCR for the fluorescence signal to cross a threshold value exceeding background level.^19,20

Samples that are negative for COVID-19 by RT-PCR do not produce a CT/CN value. Although both instruments were used for RT-PCR, the precise CT/CN values are not interchangeable and CT/CN observations over time between the 2 instruments during the disease course would be based on CT/CN value movement (general upward or downward trend) rather than absolute CT/CN differences. Both assays have been approved by emergency use authorization as qualitative tests for the presence/absence of COVID-19. Although the CT/CN value is available to laboratory staff after test completion, the CT/CN value is not reported routinely in the patient health record. All veteran patients identified on the initial review from March 28, 2020, to April 24, 2020, had all serial COVID-19 testing recorded until November 10, 2020. The CN values at the limit of detection (LOD) for the Abbott m2000 platform from the initial validation study were reviewed for reference.²¹

Results

Of 80 patients, 25 (31%) were COVID-19 positive over the course of testing. The study population had a mean age of 73.5 years; 92% were aged > 60 years. The group was predominantly male (79 male vs 1 female). Among the 77 patients with a stated ethnicity, 39 (51%) were African American. In comparison, 43% of residents in Philadelphia County are African American (Table).^22,23 Additionally, a previously published total COVID-19 tested population by ethnicity at the same regional VAMC revealed 46.8% of tested veteran patients were African American. ²⁴ Three patients had no stated ethnicity. Among those who tested positive, 11 were African American patients, 12 were White patients, and 2 had no stated ethnicity. Four patients tested positive on their first test. The other 21 patients were positive on repeat testing. Interestingly, 6 patients had 1 initial negative test before a positive test, 6 patients had 2, 8 patients had 3, and 1 patient had 4 initial negative tests before a positive test result. Among the 25 positive patients, 22 were either positive within 10 days of the initial negative test result or initially positive (Figure 2). Three patients who tested positive after 10 days did so at 16, 20, and 21 days after the initial negative test result. Among the 25 positive patients, 23 had initial and serial testing from both the Abbott and Xpert Xpress assays. The remaining 2 positive patients had initial and serial testing from the Abbott assay exclusively.

Only positive COVID-19 results by RTPCR produced a CT/CN value. After disease resolution with a negative test, no CT/CN value was produced with the negative test result on either testing platform. Because repeat testing after the initial positive result took place no sooner than 10 days, we observed that the CT/CN value increased after the initial positive result until the disease resolved, and a negative result was obtained (eAppendix 1, available online at doi:10.12788/fp.0276). A t test comparing the initial CT/CN value to the value more than 10 days after the initial positive showed the CT/CN was statistically significantly higher (P < .05).

Prompt repeat testing after the initial test can show a decrease in the CT/CN value because of increasing viral load before the expected increase until disease resolution if the initial test caught the infection early. Twelve patients had a negative test result between 2 serial positive results. These negative test results occurred later, near the end of the disease course. Among the 12 patients with this positive-negativepositive CT/CN pattern, 7 were symptomatic and no longer had documented symptoms or hospitalization around the time of this positive-negative-positive pattern. Four of these individuals were asymptomatic during the entire infection course. One of the 12 patients with this pattern expired with the negative result occurring on day 27 of the disease in the context of rising CT/CN. One of these 12 patients only had a presumptive positive test result on the Cepheid because it detected only the E target with a CT value of 38.7. In 1 of the 12 patients, the negative test result occurred between 2 positive test results with CT/CN values < 20 (12.05 and 19.05 for the positive tests before and after the negative result, respectively). When the initial CT/CN values was separated based on ethnicity, the average CT/CN value for African Americans (23.3) was higher than for other ethnicities (19.9), although it did not reach statistical significance (P = .35).

Ten of the 25 patients testing positive were admitted to the hospital, including 1 admitted 15 days before diagnosis (patient 20) and 1 admitted 80 days after diagnosis (patient 7). Among these 10 patients, 6 were admitted to the intensive care unit, including patient 7. None of the patients were intubated. Three of the 10 admitted patients died (patients 7, 20, and 24). Patient 7 was a 79-year-old male with a history of dementia, cerebrovascular accident, hypertension, hyperlipidemia, and chronic kidney disease with symptoms of lethargy and refusal of oral intake when he was diagnosed with COVID-19. He was admitted 80 days after diagnosis for hyponatremia and acute renal failure, with death on day 87 recorded as complications from the earlier COVID-19 infection. Patient 20, an 89-year-old male with a history of dementia, chronic kidney disease, and hyperlipidemia, had been admitted with fever, cough, and leukocytosis 17 days before COVID-19 diagnosis. He continued to be symptomatic after diagnosis with development of hypotension, dehydration, and refusal of oral intake while on comfort measures/endof- life care and died 15 days after COVID- 19 infection diagnosis. Patient 24 was a 96-year-old male with history of heart failure, hypertension, coronary artery disease, prostate carcinoma, and dementia who developed a cough at the time of diagnosis; because of his underlying condition, he remained in the CLC on comfort care. His symptoms, including hypoxia, worsened until he died 7 days after diagnosis.

Among the 25 patients, 17 were symptomatic at the time of diagnosis; the 14 initially symptomatic patients who survived improved clinically and returned to baseline. Eight of the 25 patients were asymptomatic initially and 3 developed symptoms 2 to 5 days after diagnosis. Only 1 patient who remained asymptomatic was admitted for inability to adhere to quarantine at the CLC. Review of the health records of all surviving symptomatic patients showed symptom resolution with return to baseline that corresponds to an increasing CT/CN value. A 1-tailed t test comparing the initial CT/ CN at the time of diagnosis to the last CT/CN value for symptomatic patients who recovered revealed a statistically significant increase (P < .05). For the symptomatic, symptom resolution and hospital discharge took (if required) a mean 20 days (range, 7-46). Among those who were not hospitalized, symptoms resolved in 7 to 36 days (18 days). Among those requiring hospitalization at any time (excluding patients who died or were asymptomatic), symptom and hospitalization resolution took a mean 22 days (range, 10-46). Asymptomatic patients (patients 8, 10, 15, 16, and 25) also showed increasing CT/CN value during the infection course, although there was no correlation with the continued lack of symptoms.

During the initial validation of the Abbott m2000 instrument, an LOD study included concentrations of 1000, 500, 250, 100, 70, 60, and 50 virus copies/mL (eAppendix 2, available online at doi:10.12788/fp.0276).21 The average CN at 100 virus copies/mL—the manufacturer provided LOD in the instructions for use—was 25.74.20 At a concentration of one-half that (50 virus copies/mL), the average CN was 28.39.

Discussion

This is the first study in the English literature to track CT/CN values as part of serial testing of a veteran CLC. Widescale testing and repeat screening in the absence of symptoms of nursing home residents would identify those who are infected and allow providers to track viral load clearance.^9-14 CT/CN values, when serially tracked during the infection course, appear to increase with illness resolution, consistent with earlier reports that CT/CN correlates with viral load.^8-14 Serial CT/CN values that are high (> 25) and continue to increase with each test suggest progression toward disease resolution or viral RNA clearance.^8-14 After symptom resolution, patients can have a persistent low level of viral shedding (corresponding to a high CT/CN value).^10-14,25 Near the end of disease resolution, a negative serial RT-PCR sample test before a subsequent positive might be a promising clinical sign of near disease recovery. Once the viral load is low with a CT/CN significantly higher than 25, some specimens might result as negative but turn up positive on subsequent sampling with a high CT/CN value. This pattern, with attendant high CT/CN values for the positive results, are consistent with the known effect of viral load (ie, a low viral load correlates to a high CT/CN) and adequacy of specimen collection on CT/CN values^.25 If the patient’s viral load is low, the sample collected might have a viral load at or near the testing platform’s LOD.

For Abbott m2000, the manufacturer provided LOD is 100 virus copies/mL, although the instrument was able to detect virus concentrations below that level during the initial validation.²⁰ The actual LOD of the instrument at our institution is < 100 virus copies/mL. For the Cepheid Xpert Xpress SARS-CoV-2 assay, the manufacturer-provided LOD is 250 virus copies/mL.19 An LOD study including samples below the manufacturer-provided LOD was not part of the initial validation study for the Xpert Xpress assay. Nonetheless, the virus concentration of samples with very high CT values at or near the maximum CT value of 45 is expected to be at or near the platform’s actual LOD.

If the samples collected near the end of the patient’s disease course have viral loads near these low concentrations, the encouraging positive-negative-positive pattern with high CT/CN values might be a promising sign for viral clearance. On the other hand, a positive-negative-positive pattern in the setting of low CT/CN values before and after the negative test might indicate poor sampling for the negative specimen. The back-and-forth or positive-negative-positive pattern generally appears to indicate near resolution of the infection course, although clinical correlation is necessary to rule out inadequate sampling earlier in the disease course or prolonged viral RNA shedding.^9-14 In all of the surviving symptomatic patients who showed the positive-negative-positive pattern, this sign occurred around or after symptom resolution. It also is important to consider that in some patients, SARS-CoV-2 RNA might remain detectable with increasing CT/CN after symptom resolution, and samples from these patients might not result positive. Therefore, CT/CN values cannot be interpreted without considering the clinical picture.²⁵

Studies on infectiousness and virus culture from COVID-19 samples with CT/ CN correlation have shown that patients with high CT/CN at the end of their disease course might not be as infectious.^9-14,25 Because 1 patient had a presumptive positive result after the negative result, this study shows that this positive-negative-positive pattern could include presumptive positive results. Also, in the setting of a recent positive result on the same testing platform, a patient with this pattern is presumed to be positive for COVID-19 RNA because of scant viral material.

Methods

A retrospective review of all COVID-19 CT/CN testing at the Corporal Michael J. Crescenz Veterans Affairs Medical Center (VAMC) CLC in Philadelphia, Pennsylvania, from March 28, 2020, to April 24, 2020, was performed with a US Department of Veterans Affairs (VA) Veterans Health Information System Architecture VistA/FileMan search. Only veteran residents were included in this review. Data collected included initial and serial test results, CT/CN on positive test results, test dates, testing platform used, demographic information (age, self-reported ethnicity, and sex), and clinical follow-up information. Health records were reviewed retrospectively to identify death, the first day after diagnosis with no documented symptoms, or hospitalization status.

RT-PCR testing was performed with the Abbott RealTime SARS-CoV-2 assay on the Abbott m2000 platform and the Xpert Xpress SARS-CoV-2 assay on the Cepheid Infinity platform. The Xpert Xpress assay gave 2 CT values for the E and N2 targets on positive samples.¹⁹ For this assay to indicate a positive specimen, amplification by RT-PCR of the N2 target or both the N2 and E target is required. The Xpert Xpress assay results as presumptive positive if only the E target amplified. This assay counts a maximum of 45 cycles. The Abbott RealTime SARS-CoV-2 assay gave 1 CN derived from the RNA-dependent RNA polymerase and N targets on positive samples.20 The Abbott assay on the m2000 counts a maximum of 37 cycles. The CT/CN value is the number of cycles required by RT-PCR for the fluorescence signal to cross a threshold value exceeding background level.^19,20

Samples that are negative for COVID-19 by RT-PCR do not produce a CT/CN value.

Although the CT/CN value is available to laboratory staff after test completion, the CT/CN value is not reported routinely in the patient health record. All veteran patients identified on the initial review from March 28, 2020, to April 24, 2020, had all serial COVID-19 testing recorded until November 10, 2020. The CN values at the limit of detection (LOD) for the Abbott m2000 platform from the initial validation study were reviewed for reference.²¹

Results

Of 80 patients, 25 (31%) were COVID-19 positive over the course of testing. The study population had a mean age of 73.5 years; 92% were aged > 60 years. The group was predominantly male (79 male vs 1 female). Among the 77 patients with a stated ethnicity, 39 (51%) were African American. In comparison, 43% of residents in Philadelphia County are African American (Table).^22,23 Additionally, a previously published total COVID-19 tested population by ethnicity at the same regional VAMC revealed 46.8% of tested veteran patients were African American. ²⁴ Three patients had no stated ethnicity. Among those who tested positive, 11 were African American patients, 12 were White patients, and 2 had no stated ethnicity. Four patients tested positive on their first test. The other 21 patients were positive on repeat testing. Interestingly, 6 patients had 1 initial negative test before a positive test, 6 patients had 2, 8 patients had 3, and 1 patient had 4 initial negative tests before a positive test result. Among the 25 positive patients, 22 were either positive within 10 days of the initial negative test result or initially positive (Figure 2). Three patients who tested positive after 10 days did so at 16, 20, and 21 days after the initial negative test result. Among the 25 positive patients, 23 had initial and serial testing from both the Abbott and Xpert Xpress assays. The remaining 2 positive patients had initial and serial testing from the Abbott assay exclusively.

Only positive COVID-19 results by RTPCR produced a CT/CN value. After disease resolution with a negative test, no CT/CN value was produced with the negative test result on either testing platform. Because repeat testing after the initial positive result took place no sooner than 10 days, we observed that the CT/CN value increased after the initial positive result until the disease resolved, and a negative result was obtained (eAppendix 1, available online at doi:10.12788/fp.0276). A t test comparing the initial CT/CN value to the value more than 10 days after the initial positive showed the CT/CN was statistically significantly higher (P < .05).

Prompt repeat testing after the initial test can show a decrease in the CT/CN value because of increasing viral load before the expected increase until disease resolution if the initial test caught the infection early. Twelve patients had a negative test result between 2 serial positive results. These negative test results occurred later, near the end of the disease course. Among the 12 patients with this positive-negativepositive CT/CN pattern, 7 were symptomatic and no longer had documented symptoms or hospitalization around the time of this positive-negative-positive pattern. Four of these individuals were asymptomatic during the entire infection course. One of the 12 patients with this pattern expired with the negative result occurring on day 27 of the disease in the context of rising CT/CN. One of these 12 patients only had a presumptive positive test result on the Cepheid because it detected only the E target with a CT value of 38.7. In 1 of the 12 patients, the negative test result occurred between 2 positive test results with CT/CN values < 20 (12.05 and 19.05 for the positive tests before and after the negative result, respectively). When the initial CT/CN values was separated based on ethnicity, the average CT/CN value for African Americans (23.3) was higher than for other ethnicities (19.9), although it did not reach statistical significance (P = .35).

Ten of the 25 patients testing positive were admitted to the hospital, including 1 admitted 15 days before diagnosis (patient 20) and 1 admitted 80 days after diagnosis (patient 7). Among these 10 patients, 6 were admitted to the intensive care unit, including patient 7. None of the patients were intubated. Three of the 10 admitted patients died (patients 7, 20, and 24). Patient 7 was a 79-year-old male with a history of dementia, cerebrovascular accident, hypertension, hyperlipidemia, and chronic kidney disease with symptoms of lethargy and refusal of oral intake when he was diagnosed with COVID-19. He was admitted 80 days after diagnosis for hyponatremia and acute renal failure, with death on day 87 recorded as complications from the earlier COVID-19 infection. Patient 20, an 89-year-old male with a history of dementia, chronic kidney disease, and hyperlipidemia, had been admitted with fever, cough, and leukocytosis 17 days before COVID-19 diagnosis. He continued to be symptomatic after diagnosis with development of hypotension, dehydration, and refusal of oral intake while on comfort measures/endof- life care and died 15 days after COVID- 19 infection diagnosis. Patient 24 was a 96-year-old male with history of heart failure, hypertension, coronary artery disease, prostate carcinoma, and dementia who developed a cough at the time of diagnosis; because of his underlying condition, he remained in the CLC on comfort care. His symptoms, including hypoxia, worsened until he died 7 days after diagnosis.

Among the 25 patients, 17 were symptomatic at the time of diagnosis; the 14 initially symptomatic patients who survived improved clinically and returned to baseline. Eight of the 25 patients were asymptomatic initially and 3 developed symptoms 2 to 5 days after diagnosis. Only 1 patient who remained asymptomatic was admitted for inability to adhere to quarantine at the CLC. Review of the health records of all surviving symptomatic patients showed symptom resolution with return to baseline that corresponds to an increasing CT/CN value. A 1-tailed t test comparing the initial CT/ CN at the time of diagnosis to the last CT/CN value for symptomatic patients who recovered revealed a statistically significant increase (P < .05). For the symptomatic, symptom resolution and hospital discharge took (if required) a mean 20 days (range, 7-46). Among those who were not hospitalized, symptoms resolved in 7 to 36 days (18 days). Among those requiring hospitalization at any time (excluding patients who died or were asymptomatic), symptom and hospitalization resolution took a mean 22 days (range, 10-46). Asymptomatic patients (patients 8, 10, 15, 16, and 25) also showed increasing CT/CN value during the infection course, although there was no correlation with the continued lack of symptoms.

During the initial validation of the Abbott m2000 instrument, an LOD study included concentrations of 1000, 500, 250, 100, 70, 60, and 50 virus copies/mL (eAppendix 2, available online at doi:10.12788/fp.0276).21 The average CN at 100 virus copies/mL—the manufacturer provided LOD in the instructions for use—was 25.74.20 At a concentration of one-half that (50 virus copies/mL), the average CN was 28.39.

Discussion

This is the first study in the English literature to track CT/CN values as part of serial testing of a veteran CLC. Widescale testing and repeat screening in the absence of symptoms of nursing home residents would identify those who are infected and allow providers to track viral load clearance.^9-14 CT/CN values, when serially tracked during the infection course, appear to increase with illness resolution, consistent with earlier reports that CT/CN correlates with viral load.^8-14 Serial CT/CN values that are high (> 25) and continue to increase with each test suggest progression toward disease resolution or viral RNA clearance.^8-14 After symptom resolution, patients can have a persistent low level of viral shedding (corresponding to a high CT/CN value).^10-14,25 Near the end of disease resolution, a negative serial RT-PCR sample test before a subsequent positive might be a promising clinical sign of near disease recovery. Once the viral load is low with a CT/CN significantly higher than 25, some specimens might result as negative but turn up positive on subsequent sampling with a high CT/CN value. This pattern, with attendant high CT/CN values for the positive results, are consistent with the known effect of viral load (ie, a low viral load correlates to a high CT/CN) and adequacy of specimen collection on CT/CN values^.25 If the patient’s viral load is low, the sample collected might have a viral load at or near the testing platform’s LOD.

For Abbott m2000, the manufacturer provided LOD is 100 virus copies/mL, although the instrument was able to detect virus concentrations below that level during the initial validation.²⁰ The actual LOD of the instrument at our institution is < 100 virus copies/mL. For the Cepheid Xpert Xpress SARS-CoV-2 assay, the manufacturer-provided LOD is 250 virus copies/mL.19 An LOD study including samples below the manufacturer-provided LOD was not part of the initial validation study for the Xpert Xpress assay. Nonetheless, the virus concentration of samples with very high CT values at or near the maximum CT value of 45 is expected to be at or near the platform’s actual LOD.

If the samples collected near the end of the patient’s disease course have viral loads near these low concentrations, the encouraging positive-negative-positive pattern with high CT/CN values might be a promising sign for viral clearance. On the other hand, a positive-negative-positive pattern in the setting of low CT/CN values before and after the negative test might indicate poor sampling for the negative specimen. The back-and-forth or positive-negative-positive pattern generally appears to indicate near resolution of the infection course, although clinical correlation is necessary to rule out inadequate sampling earlier in the disease course or prolonged viral RNA shedding.^9-14 In all of the surviving symptomatic patients who showed the positive-negative-positive pattern, this sign occurred around or after symptom resolution. It also is important to consider that in some patients, SARS-CoV-2 RNA might remain detectable with increasing CT/CN after symptom resolution, and samples from these patients might not result positive. Therefore, CT/CN values cannot be interpreted without considering the clinical picture.²⁵

Studies on infectiousness and virus culture from COVID-19 samples with CT/ CN correlation have shown that patients with high CT/CN at the end of their disease course might not be as infectious.^9-14,25 Because 1 patient had a presumptive positive result after the negative result, this study shows that this positive-negative-positive pattern could include presumptive positive results. Also, in the setting of a recent positive result on the same testing platform, a patient with this pattern is presumed to be positive for COVID-19 RNA because of scant viral material.

Taiwan’s public health response to the outbreak illustrates the ability to mitigate an outbreak throughout a society.²⁶ These actions could help blunt an outbreak within a civilian nursing home population.⁵ Mitigation within a veteran CLC population has been documented, but the study, which focused on mitigation, did not consider CT/CN values, demographic distribution, testing access of the studied population, or laboratory findings related to disease pathophysiology.¹⁵ A key ingredient in widescale, serial testing is the availability of a rapid turnaround from testing in-house that allowed identification within 24 hours instead of several days at a reference laboratory. ¹⁵ Rapid widescale testing would allow clinical teams to optimize the Triangle of Benefit of Widescale Timely Tests for CLC (Figure 3).¹⁵ Timely laboratory testing remains pivotal for CLC veteran residents to aid successful clinical triage and management. Reporting serial CT/CN values can provide additional information to clinicians about the disease course because CT/ CN correlates with viral load, which varies based on where the patient is in the disease course.^9-14 CT/CN values carry significant prognostic value, particularly with respect to intubation and mortality.⁸

Limitations

Important limitations to our study include the use of 2 separate RT-PCR platforms. Using different RT-PCR platforms is common in clinical laboratories trying to take advantage of the unique characteristics of different platforms—for example, turnaround time vs high throughput— to manage COVID-19 testing workflow.²⁵ However, the exact CT/CN values obtained from each platform might not translate to the other, and the general trend (CT/CN values are rising or falling across serial tests) rather than a single value could be useful for clinical correlation. Even when the same platform is used for the serial testing, CT/CN values can be affected by adequacy of specimen collection; therefore, clinical correlation and considering the trend in CT/CN values is necessary for interpretation.^10-14,25 Because of the known trend in viral dynamics, a positive specimen collected with a high CT/CN followed by a subsequent (within 2 days) positive specimen collected with a low CT/CN might be compatible with early detection of COVID- 19 infection in the appropriate clinical context. ^10-14 However, detection late in the infection course or even after the symptomatic disease resolved with prolonged viral shedding might show serial positive samples with increasing CT/CN values.^10-14

Patients with prolonged viral shedding might not be infectious.27 Because of the clinical correlation required for interpretation and the other factors that might affect CT/CN values, recommendations advise against using CT/CN values in clinical practice at this time, although these recommendations could change with future research.25 Serial CT/CN values have the potential, if appropriately correlated with the clinical picture, to provide useful information, such as whether the viral load of the sample is relatively high or low and increasing or decreasing.

Veterans, as a population, are more susceptible to poor health outcomes and morbidity compared with similar civilian counterparts.^2,14-16 Veteran CLC patients likely would experience worse outcomes with COVID-19, including more infections, expiration, and morbidity compared with similar general population nursing homes. Similar to what had been reported for the civilian population, a trend (high CT/CN values early in the disease course with repeat testing needed to detect all positives followed by lower CT/CN value to correlate with increased viral load and then increased CT/CN value as the infection resolved) also was observed in this veteran population.

It has been extensively documented that minority groups experience decreased health care access and worse health outcomes. ^28-30 Considering the critical medical supply shortages, including personal protective equipment, ventilators, and even testing supplies, there is the potential for a resource access disparity by ethnicity.^28-31 Because the VA does not depend on measures of wealth and privilege such as health insurance, there was no disparity noted in access to testing by race or ethnicity at the VAMC CLC. When considering the health outcome of viral load from the measured CT/CN value, the viral loads of African American patients and those of other ethnicities was not significantly different in this study.

Conclusions

This is the first study to bring up critical points including serial CT/CN value correlation in RT-PCR tests, demographic distributions demonstrating easy and equal access in a veteran nursing home to COVID-19 testing, and clinical laboratory signs related to disease pathophysiology. Unlike other populations who have undergone serial CT/CN monitoring, nursing homes represent a particularly vulnerable population who require measures to prevent the spread and mitigate outbreaks of COVID-19.^2,4,5 Test measurements obtained such as the CT/CN value during routine clinical care can provide useful information for public health, epidemiologic, or clinical purposes with appropriate correlation to clinical and other laboratory parameters. This study demonstrates early intervention of serial testing of an outbreak in a veterans nursing home with CT/CN value correlation.

It all began with the question, “Has your butt been getting enough attention?”

Though that may seem unorthodox, it led researchers to discovering a treatment that may help prevent anal cancer in people with HIV/AIDS. It’s still featured on their study’s website, with this further explanation: “You get your viral load checked, your T-cell count checked, but what about your anus? Did you know that half of HIV+ men have cell changes in their anus caused by HPV?”

The Anal Cancer/HSIL Outcomes Research (ANCHOR) study, led by Joel Palefsky, MD, was published  in The New England Journal of Medicine. Dr. Palefsky, an infectious disease expert at the University of California, San Francisco, and his team set out to determine whether a treatment that prevents cervical cancer in people with human papillomavirus (HPV) would benefit people with HIV/AIDS. The new treatment reduced the likelihood of anal cancer by more than 50%.

The team worked over 7 years, during which time they tested 4,459 men, women, transgender, and nonbinary individuals at 25 sites across the United States. The participants were sorted into two groups: Some received treatment for high-grade squamous intraepithelial lesions (HSILs), and some did not but were monitored for signs of disease. These included individuals over 35 who were living with HIV/AIDS and who were found to have patches of abnormal cells in their rectal lining.

HSILs are the cells gynecologists look for in performing a pap smear. They are precancerous cells commonly found in the cervix of persons with HPV. Finding HSILs during a gynecologic examination alerts clinicians to potential problems.

HSILs can also be found in the anal tract of men and women with HIV. Dr. Palefsky therefore hypothesized that, as with HPV and cervical cancer, these anal HSILs may be a precursor of anal cancer.

The scientists decided to treat these cells the same way they would treat them if found in the cervix and to see whether that reduced the risk of cancer. Doctors used lidocaine to numb the area, then removed the HSILs with an electric probe. The team then assessed whether the treatment prevented people from getting cancer.

It turns out that in many cases, it did. The study concluded after 30 of the participants developed anal cancer. Of those, 21 patients had not received HSIL treatment, compared with nine who did receive the treatment. The treatment resulted in a 57% reduction in the rate of anal cancer among patients who received treatment for their HSILs.

These results are encouraging, said Aasma Shaukat, MD, director of outcomes research in the Division of Gastroenterology and Hepatology at NYU Langone Health. Dr. Shaukat was not involved with the study. She believes it’s going to cause ripples across the field.

“The study is likely to change guidelines in favor of active and early treatment for HSIL and away from watchful waiting in individuals living with HIV to reduce the risk of developing anal squamous cell carcinoma, akin to removing polyps during colonoscopy to progression to and incidence of colorectal cancer,” she said in an email interview.

Treatments for this group of patients are more important now than ever. Since the beginning of the AIDS epidemic in the 1980s, the number of people with HIV has increased, Dr. Palefsky detailed in a press conference announcing the ANCHOR results. That’s partially because of new transmissions and partially owing to the fact that new treatments make it possible for people with HIV to live long, healthy lives. So as more people with HIV move into their sunset years, there are more people at risk for developing cancer, which is a disease associated with aging. Anal cancer sits at the intersection of risk for aging people who have HIV.

Any defense we have against the risk of cancer in this growing demographic is a good thing, says Hanna K. Sanoff, MD, a gastrointestinal oncologist at the Lineberger Comprehensive Cancer Center, University of North Carolina at Chapel Hill, who was also not involved in the study. Although it’s not ready to be applied in doctors’ offices now, it could be a tool in the future. “Anything we can do to try and decrease the chance of precancerous lesions progressing to a real invasive cancer is of great importance. This kind of prevention work is critical to helping minimize the burden of cancer on our communities,” Dr. Sanoff said in an interview.

The study was funded by the National Cancer Institute of the National Institutes of Health and was conducted through the NCI-supported AIDS Malignancy Consortium. Dr. Shaukat and Dr. Sanoff report no relevant financial relationships.

Young Black sexual-minority men (YBSMM) who experience sleep disturbance at least 3-4 times a week are much more likely to miss HIV pre-exposure prophylaxis (PrEP) doses than those who rarely report sleep disturbance, according to a new study published online in the journal AIDS and Behavior.

Sleep disturbance, poor cognitive processing, and memory function deficits go hand in hand, especially among people living with HIV. 

Data have suggested that poor sleep might be an important factor in common neurocognitive complaints and overall health outcomes, especially among older adults with HIV. But few studies have examined the role that sleep quality might play in driving health behaviors around prevention and PrEP adherence, especially among YBSMM, who are at highest risk for acquiring new HIV infections.

Commonly cited reasons for suboptimal HIV prevention efforts within this population often include stigma, mistrust of the medical system, and a lack of culturally appropriate care.

“We make a lot of assumptions about young people and their brains and their ability to remember things, namely [that] they should be better than older adults at remembering to take medications,” lead study investigator Jade Pagkas-Bather, MD, an infectious disease specialist at University of Chicago Medicine, told this news organization. 

“In reality, many young people are not used to taking medications, [especially] for a disease that they do not have.”
 

Too many pills, too little sleep

The researchers examined data collected from participants in the Neighborhoods and Networks Cohort Study, Chicago, which looked at the role of social, contextual, network, and geospatial factors influencing HIV prevention and care in HIV-negative, cisgender YBSMM between 2018 and 2019. 

The investigators included 70 YBSMM participants who reported current PrEP use in the analysis. All were between the ages of 16 and 24 years, self-identified as African American or Black, were assigned male at birth, and reported at least one sexual encounter with a man or transgender woman in the previous 12 months.

Sleep was measured using the Patient Health Questionnaire-9 (PHQ-9) which includes a question on frequency of sleep disturbance (that is, trouble falling asleep, staying asleep, or sleeping too much) categorized as follows: less than 1 day (rarely or none of the time), 1-2 days (some or a little of the time), 3-4 days (occasionally or a moderate amount of time), or 5-7 days (all of the time).

Almost half (47.1%) of participants self-reported some or moderate sleep disturbance, with 8.6% having sleep disturbance all of the time. 

“One of the main findings was that poor sleep and having too many pills impacts people’s ability to remember to take their PrEP or is associated with missing PrEP doses,” explained Dr. Pagkas-Bather.

In adjusted models, YBSMM who reported moderate sleep disturbances cited having too many pills to take as the reason for missing or forgetting PrEP doses (adjusted odds ratio, 7.59; 95% confidence interval, 1.05-54.57), compared with peers who did not have sleep issues.

Depression was likewise an important factor. Participants who reported experiencing sleep disturbance all of the time and missing PrEP doses were also highly likely to be depressed (aOR, 11.30; 95% CI, 1.19-107.53).

“The PHQ-9 is a widely accepted measure looking at depression – and sleep as one symptom of depression,” explained Brooke Genkin Rogers, Ph.D., M.P.H., a research scientist and assistant professor of psychiatry and human behavior at the Warren Alpert Medical School of Brown University, Providence, R.I. 

Dr. Rogers, who was not involved in the study, noted, “Sleep disturbance is a sign of poor physical or mental health, particularly in an otherwise younger, healthier population.” But Dr. Rogers also had questions about sleep duration (that is, too short or too long) and whether or not it also played a role in poor adherence, information that was not pursued within the study. 

“As a clinician, I see quite a few people who are young Black sexual minority men who are on PrEP, or on the converse side, people living with HIV and taking medications for HIV treatment. I would posit a guess that it’s not that people are necessarily sleeping too much, but there are other sorts of factors that interfere with being able to get 8 hours of sleep a night,” explained Dr. Pagkas-Bather.

They include structural issues like greater exposure to housing instability and neighborhood safety. 

However, Dr. Pagkas-Bather pointed to an even more critical factor influencing PrEP usage and adherence, one that she refers to as “Trickle Up HIV Care.”

“We can’t just come up with interventions, drugs, and studies and say, we have all of these options, anyone who wants them, come and get them,” she said. “We really need to work very hard at educating and encouraging populations who have no high-level need for prevention and treatment.”

As a clinician who works closely with the YBSMM population, Dr. Pagkas-Bather also shared that her patients have told her that they’ve asked for PrEP and have had providers turn them down because they weren’t comfortable prescribing PrEP or made assumptions about the kind of people who are on PrEP. 

“There are sometimes assumptions made about Black men and sexual promiscuity. And the data doesn’t bear that out. It’s not that Black men are having more sex than White men or any other man; it’s that the prevalence of HIV in the Black community is higher overall relative to the population,” noted Dr. Pagkas-Bather.

“We need a nuanced approach to examining these issues ... to take a look at multiple levels of influence on folks’ health and HIV risk,” said Dr. Rogers.

Both clinicians acknowledged that creative solutions have not been exhausted. 

“There’s a lot of opportunity if we sit down with communities and share in decisions around HIV treatment and prevention ... if we tap into the wealth and knowledge of the Black communities to prevent HIV,” concluded Dr. Pagkas-Bather.

Dr. Pagkas-Bather reports that she is a Gilead Sciences HIV Research Scholar awardee. Dr. Rogers reports receiving a scientific research grant from Gilead Sciences.

“There’s a lot of opportunity if we sit down with communities and share in decisions around HIV treatment and prevention ... if we tap into the wealth and knowledge of the Black communities to prevent HIV,” concluded Dr. Pagkas-Bather.

Young Black sexual-minority men (YBSMM) who experience sleep disturbance at least 3-4 times a week are much more likely to miss HIV pre-exposure prophylaxis (PrEP) doses than those who rarely report sleep disturbance, according to a new study published online in the journal AIDS and Behavior.

Sleep disturbance, poor cognitive processing, and memory function deficits go hand in hand, especially among people living with HIV. 

Data have suggested that poor sleep might be an important factor in common neurocognitive complaints and overall health outcomes, especially among older adults with HIV. But few studies have examined the role that sleep quality might play in driving health behaviors around prevention and PrEP adherence, especially among YBSMM, who are at highest risk for acquiring new HIV infections.

Commonly cited reasons for suboptimal HIV prevention efforts within this population often include stigma, mistrust of the medical system, and a lack of culturally appropriate care.

“We make a lot of assumptions about young people and their brains and their ability to remember things, namely [that] they should be better than older adults at remembering to take medications,” lead study investigator Jade Pagkas-Bather, MD, an infectious disease specialist at University of Chicago Medicine, told this news organization. 

“In reality, many young people are not used to taking medications, [especially] for a disease that they do not have.”
 

Too many pills, too little sleep

The researchers examined data collected from participants in the Neighborhoods and Networks Cohort Study, Chicago, which looked at the role of social, contextual, network, and geospatial factors influencing HIV prevention and care in HIV-negative, cisgender YBSMM between 2018 and 2019. 

The investigators included 70 YBSMM participants who reported current PrEP use in the analysis. All were between the ages of 16 and 24 years, self-identified as African American or Black, were assigned male at birth, and reported at least one sexual encounter with a man or transgender woman in the previous 12 months.

Sleep was measured using the Patient Health Questionnaire-9 (PHQ-9) which includes a question on frequency of sleep disturbance (that is, trouble falling asleep, staying asleep, or sleeping too much) categorized as follows: less than 1 day (rarely or none of the time), 1-2 days (some or a little of the time), 3-4 days (occasionally or a moderate amount of time), or 5-7 days (all of the time).

Almost half (47.1%) of participants self-reported some or moderate sleep disturbance, with 8.6% having sleep disturbance all of the time. 

“One of the main findings was that poor sleep and having too many pills impacts people’s ability to remember to take their PrEP or is associated with missing PrEP doses,” explained Dr. Pagkas-Bather.

In adjusted models, YBSMM who reported moderate sleep disturbances cited having too many pills to take as the reason for missing or forgetting PrEP doses (adjusted odds ratio, 7.59; 95% confidence interval, 1.05-54.57), compared with peers who did not have sleep issues.

Depression was likewise an important factor. Participants who reported experiencing sleep disturbance all of the time and missing PrEP doses were also highly likely to be depressed (aOR, 11.30; 95% CI, 1.19-107.53).

“The PHQ-9 is a widely accepted measure looking at depression – and sleep as one symptom of depression,” explained Brooke Genkin Rogers, Ph.D., M.P.H., a research scientist and assistant professor of psychiatry and human behavior at the Warren Alpert Medical School of Brown University, Providence, R.I. 

Dr. Rogers, who was not involved in the study, noted, “Sleep disturbance is a sign of poor physical or mental health, particularly in an otherwise younger, healthier population.” But Dr. Rogers also had questions about sleep duration (that is, too short or too long) and whether or not it also played a role in poor adherence, information that was not pursued within the study. 

“As a clinician, I see quite a few people who are young Black sexual minority men who are on PrEP, or on the converse side, people living with HIV and taking medications for HIV treatment. I would posit a guess that it’s not that people are necessarily sleeping too much, but there are other sorts of factors that interfere with being able to get 8 hours of sleep a night,” explained Dr. Pagkas-Bather.

They include structural issues like greater exposure to housing instability and neighborhood safety. 

However, Dr. Pagkas-Bather pointed to an even more critical factor influencing PrEP usage and adherence, one that she refers to as “Trickle Up HIV Care.”

“We can’t just come up with interventions, drugs, and studies and say, we have all of these options, anyone who wants them, come and get them,” she said. “We really need to work very hard at educating and encouraging populations who have no high-level need for prevention and treatment.”

As a clinician who works closely with the YBSMM population, Dr. Pagkas-Bather also shared that her patients have told her that they’ve asked for PrEP and have had providers turn them down because they weren’t comfortable prescribing PrEP or made assumptions about the kind of people who are on PrEP. 

“There are sometimes assumptions made about Black men and sexual promiscuity. And the data doesn’t bear that out. It’s not that Black men are having more sex than White men or any other man; it’s that the prevalence of HIV in the Black community is higher overall relative to the population,” noted Dr. Pagkas-Bather.

“We need a nuanced approach to examining these issues ... to take a look at multiple levels of influence on folks’ health and HIV risk,” said Dr. Rogers.

Both clinicians acknowledged that creative solutions have not been exhausted. 

“There’s a lot of opportunity if we sit down with communities and share in decisions around HIV treatment and prevention ... if we tap into the wealth and knowledge of the Black communities to prevent HIV,” concluded Dr. Pagkas-Bather.

Crenezumab, an investigational medication designed to slow or prevent Alzheimer’s disease (AD), provides no cognitive benefit in patients at high genetic risk, new research suggests.

Top-line results for a phase 2 trial showed the novel drug, a monoclonal antibody designed to neutralize neurotoxic oligomers (a form of beta-amyloid), was not statistically superior to placebo in terms of cognitive ability or episodic memory function among cognitively unimpaired individuals with a genetic mutation for early-onset AD.

Genentech announced the negative results on June 16 together with Banner Alzheimer’s Institute, Phoenix.

During a press briefing, company representatives and researchers expressed disappointment with the initial results – but stressed numerous ongoing analyses have yet to be completed.

“This is the beginning of the story, but by no means the end of it,” Pierre N. Tariot, MD, director, Banner Alzheimer’s Institute, and one of the study leaders, said at the briefing.

API ADAD trial

The prospective, double-blind parallel-group Alzheimer’s Prevention Initiative (API) Autosomal Dominant Alzheimer’s Disease (ADAD) phase 2 trial enrolled 252 members of the world’s largest extended family with ADAD in Colombia. A total of 94% of the participants completed the study.

Two-thirds of participants carried the Presenilin 1 (PSEN1) E280A mutation, which virtually guarantees that carriers will develop AD at an average age of 44 years and dementia at an average age of 49 years.

Study participants were randomly assigned to receive crenezumab or placebo over a period of 5-8 years. The dose of crenezumab was increased at different time points during the trial as knowledge about potential treatment approaches for AD evolved.

Dr. Tariot noted the maximum dose was not provided for the entire treatment period. “The longest people received the highest dose was about 2 years,” he added.

Coprimary endpoints were rate of change in cognitive abilities, as measured by the API ADAD composite cognitive score, or episodic memory function, measured by the Free and Cued Selective Reminding Test Cueing Index.

Results showed these outcomes were not statistically significant for those receiving the active medication.

In addition to a range of cognitive measures, researchers also assessed amyloid PET and, later in the study, tau PET. MRI and cerebrospinal fluid (CSF) measures were also examined.

The investigators did find small numerical differences favoring crenezumab across the coprimary and multiple secondary and exploratory endpoints, but these were also not statistically significant.

Finally, no new safety issues were identified with crenezumab during the study.

Further analyses of data are ongoing and additional brain imaging and CSF biomarker results will be presented at the Alzheimer’s Association International Conference on Aug. 2.

While the study was not positive, it demonstrated that prevention trials are possible, even in less-than-ideal circumstances and generated a wealth of useful data, the investigators note.

“There were some differences between the treated and untreated patients, and we still need to understand which patients were most likely to experience those differences,” Rachelle Doody, MD, PhD, global head of neurodegeneration at Roche and Genentech, told briefing attendees.

“We need to understand the biomarkers involved and what [they’re] telling us about the disease and the timing of the intervention,” Dr. Doody said.

Prevention “needs to be one of our targeted therapeutic approaches but probably not our only one,” she added.

Beyond amyloid?

Commenting on the negative results, Howard Fillit, MD, cofounder and chief science officer of the Alzheimer’s Drug Discovery Foundation, said they demonstrate the need to focus beyond amyloid and more on the biology of aging.

“This broader approach coupled with advances in novel biomarkers is bringing us closer to the day when physicians will be able to zero in on the root causes of each patient’s Alzheimer’s – and tailor combinations of drug therapies to provide precision medicine,” Dr. Fillit, who was not involved with the research, said in statement.

Genentech is also evaluating the potential of gantenerumab for ADAD and for the prevention of sporadic AD and treatment of early Alzheimer’s in late-stage clinical trials. Results from the phase 3 GRADUATE studies of gantenerumab in early AD are expected by the end of the year.

The study was supported by the National Institute on Aging, contributions to Banner Alzheimer’s Foundation, and Genentech.
