Concern and anxiety around COVID-19 remains high among Americans, with more people reporting mental health effects from the pandemic this year than last, and parents concerned about the mental health of their children, results of a new poll by the American Psychiatric Association show. Although the overall level of anxiety has decreased from last year’s APA poll, “the degree to which anxiety still reigns is concerning,” APA President Jeffrey Geller, MD, MPH, told this news organization.

The results of the latest poll were presented at the American Psychiatric Association 2021 annual meeting and based on an online survey conducted March 26 to April 5 among a sample of 1,000 adults aged 18 years or older.

Serious mental health hit

In the new poll, about 4 in 10 Americans (41%) report they are more anxious than last year, down from just over 60%.

Young adults aged 18-29 years (49%) and Hispanic/Latinos (50%) are more likely to report being more anxious now than a year ago. Those 65 or older (30%) are less apt to say they feel more anxious than last year.

The latest poll also shows that Americans are more anxious about family and loved ones getting COVID-19 (64%) than about catching the virus themselves (49%). 

Concern about family and loved ones contracting COVID-19 has increased since last year’s poll (conducted September 2020), rising from 56% then to 64% now. Hispanic/Latinx individuals (73%) and African American/Black individuals (76%) are more anxious about COVID-19 than White people (59%).

In the new poll, 43% of adults report the pandemic has had a serious impact on their mental health, up from 37% in 2020. Younger adults are more apt than older adults to report serious mental health effects.

Slightly fewer Americans report the pandemic is affecting their day-to-day life now as compared to a year ago, in ways such as problems sleeping (19% down from 22%), difficulty concentrating (18% down from 20%), and fighting more with loved ones (16% down from 17%).

The percentage of adults consuming more alcohol or other substances/drugs than normal increased slightly since last year (14%-17%). Additionally, 33% of adults (40% of women) report gaining weight during the pandemic.

Call to action

More than half of adults (53%) with children report they are concerned about the mental state of their children and almost half (48%) report the pandemic has caused mental health problems for one or more of their children, including minor problems for 29% and major problems for 19%.

More than a quarter (26%) of parents have sought professional mental health help for their children because of the pandemic.

Nearly half (49%) of parents of children younger than 18 years say their child received help from a mental health professional since the start of the pandemic; 23% received help from a primary care professional, 18% from a psychiatrist, 15% from a psychologist, 13% from a therapist, 10% from a social worker, and 10% from a school counselor or school psychologist.

More than 1 in 5 parents reported difficulty scheduling appointments for their child with a mental health professional.

“This poll shows that, even as vaccines become more widespread, Americans are still worried about the mental state of their children,” Dr. Geller said in a news release.

“This is a call to action for policymakers, who need to remember that, in our COVID-19 recovery, there’s no health without mental health,” he added.

Just over three-quarters (76%) of those surveyed say they have been or intend to get vaccinated; 22% say they don’t intend to get vaccinated; and 2% didn’t know.

For those who do not intend to get vaccinated, the primary concern (53%) is about side effects of the vaccine. Other reasons for not getting vaccinated include believing the vaccine is not effective (31%), believing the makers of the vaccine aren’t being honest about what’s in it (27%), and fear/anxiety about needles (12%).

Resiliency a finite resource

Reached for comment, Samoon Ahmad, MD, professor in the department of psychiatry, New York University, said it’s not surprising that Americans are still suffering more anxiety than normal.

“The Census Bureau’s Household Pulse Survey has shown that anxiety and depression levels have remained higher than normal since the pandemic began. That 43% of adults now say that the pandemic has had a serious impact on their mental health seems in line with what that survey has been reporting for over a year,” Dr. Ahmad, who serves as unit chief of inpatient psychiatry at Bellevue Hospital Center in New York, said in an interview.

He believes there are several reasons why anxiety levels remain high. One reason is something he’s noticed among his patients for years. “Most people struggle with anxiety especially at night when the noise and distractions of contemporary life fade away. This is the time of introspection,” he explained.

“Quarantine has been kind of like a protracted night because the distractions that are common in the so-called ‘rat race’ have been relatively muted for the past 14 months. I believe this has caused what you might call ‘forced introspection,’ and that this is giving rise to feelings of anxiety as people use their time alone to reassess their careers and their social lives and really begin to fret about some of the decisions that have led them to this point in their lives,” said Dr. Ahmad.

The other finding in the APA survey – that people are more concerned about their loved ones catching the virus than they were a year ago – is also not surprising, Dr. Ahmad said.

“Even though we seem to have turned a corner in the United States and the worst of the pandemic is behind us, the surge that went from roughly November through March of this year was more wide-reaching geographically than previous waves, and I think this made the severity of the virus far more real to people who lived in communities that had been spared severe outbreaks during the surges that we saw in the spring and summer of 2020,” Dr. Ahmad told this news organization.

“There’s also heightened concern over variants and the efficacy of the vaccine in treating these variants. Those who have families in other countries where the virus is surging, such as India or parts of Latin America, are likely experiencing additional stress and anxiety too,” he noted.

While the new APA poll findings are not surprising, they still are “deeply concerning,” Dr. Ahmad said.

“Resiliency is a finite resource, and people can only take so much stress before their mental health begins to suffer. For most people, this is not going to lead to some kind of overdramatic nervous breakdown. Instead, one may notice that they are more irritable than they once were, that they’re not sleeping particularly well, or that they have a nagging sense of discomfort and stress when doing activities that they used to think of as normal,” like taking a trip to the grocery store, meeting up with friends, or going to work, Dr. Ahmad said.

“Overcoming this kind of anxiety and reacclimating ourselves to social situations is going to take more time for some people than others, and that is perfectly natural,” said Dr. Ahmad, founder of the Integrative Center for Wellness in New York.

“I don’t think it’s wise to try to put a limit on what constitutes a normal amount of time to readjust, and I think everyone in the field of mental health needs to avoid pathologizing any lingering sense of unease. No one needs to be medicated or diagnosed with a mental illness because they are nervous about going into public spaces in the immediate aftermath of a pandemic. We need to show a lot of patience and encourage people to readjust at their own pace for the foreseeable future,” Dr. Ahmad said.

Dr. Geller and Dr. Ahmad have disclosed no relevant financial relationships.

Teens with persistent nocturnal asthma symptoms were significantly more likely than were those without nighttime asthma to report poor functional health independent of daytime asthma, based on data from 430 adolescents aged 12-16 years.

Approximately half of children with severe asthma experience at least one night of inadequate sleep per week, and lost sleep among young children with asthma has been associated with impaired physical function, school absence, and worsened mood. However, the effect of asthma-related sleep disruption on daily function in teenagers in particular has not been well studied, according to Anne Zhang of the University of Rochester (N.Y.) and colleagues.

In a poster presented at the virtual meeting of the Pediatric Academic Societies (#542), the researchers reviewed baseline survey data from the School-Based Asthma Care for Teens (SB-ACT) study, a randomized, controlled trial conducted from 2014 to 2018 in Rochester, N.Y.

The average age of the respondents was 13.4 years, 56% were male, 56% were African American, 32% were Hispanic, and 84% had Medicaid insurance.

Persistent nocturnal asthma was defined as 2 or more nights of nighttime awakening in the past 14 days, and intermittent nocturnal asthma was defined as less than 2 nights of nighttime awakening in the past 14 days.

Overall, teens with persistent nocturnal asthma were significantly more likely than were those with intermittent nocturnal asthma to report physical limitations during strenuous activity (58% vs. 41%), moderate activity (32% vs. 19%), and school gym classes (36% vs. 19%; P <.01 for all).

In addition to physical impact, teens with persistent nocturnal asthma were more likely than were those with intermittent nocturnal asthma to report depressive symptoms (41% vs. 23%), asthma-related school absences in the past 14 days (0.81 vs. 0.12), and poorer quality of life (4.6 vs. 5.9, P <.01 for all).

The results remained significant in a multivariate analysis that controlled for daytime asthma symptoms, weight status, race, ethnicity, gender, age, and smoke exposure, the researchers said.

The study findings were limited by several factors including the cross-sectional design, potential of recall bias in survey responses, and lack of data on sleep duration and quality, the researchers noted.

However, the results suggest that improving nighttime asthma control for teens may improve daily function, and providers should ask teens with asthma about the possible effect and burden of nighttime symptoms, they said. Potential strategies to improve persistent nocturnal asthma symptoms include adjusting the timing of medications or physical activity, they added.

“We know that getting adequate, high-quality sleep is important for health - especially for adolescents,” said Kelly A. Curran, MD, of the University of Oklahoma Health Sciences Center, in an interview. “Just like adults, tired teens are not able to function at their best and are at higher risk of developing mood problems,” she said.

However, “There are already so many barriers for teens getting good sleep, such as screen time/social media, homework, busy social calendars, caffeine use, and early morning school start times,” she said. Underlying medical conditions such as depression, anxiety, and obstructive sleep apnea also can contribute to poor sleep for teens, she added.

“In my practice, I frequently counsel about sleep hygiene because it is so essential and not commonly followed,” said Dr. Curran. “Nocturnal asthma is another contributor to poor sleep - not one that I have been regularly screening for - and something we can potentially intervene in to help improve health and quality of life,” she emphasized.

Dr. Curran said that she was not surprised by the study findings, given what is known about the importance of sleep. In clinical practice, “Teens who have asthma should be screened for nocturnal symptoms as these are linked to worsened quality of life, including limitations in activities, depressive symptoms, and asthma-related school absence,” she said.

However, additional research is needed to better understand whether improving nocturnal asthma symptoms can help improve quality of life and daily functioning in adolescents, she noted.

The SB-ACT was supported by the National Institutes of Health. Ms. Zhang was supported in part by the OME-CACHED for medical student research and an NIH grant. The researchers had no financial conflicts to disclose. Dr. Curran had no financial conflicts to disclose.

In clinical practice, “Teens who have asthma should be screened for nocturnal symptoms as these are linked to worsened quality of life, including limitations in activities, depressive symptoms, and asthma-related school absence,” she said.

However, additional research is needed to better understand whether improving nocturnal asthma symptoms can help improve quality of life and daily functioning in adolescents, she noted.

Accelerated brain aging among HIV-infected adults might be caused in part by altered deep sleep patterns, new research suggests.

Using a measure known as the brain age index (BAI) – a machine-learning model that measures deviations in brain activity during sleep relative to healthy individuals – investigators identified 34 sleep electroencephalogram features that were significantly altered by HIV infection. The most notable of these was the decline in slow-wave activity during non-REM sleep, which has been previously associated with MRI markers of brain aging in healthy adults.

“One of the functions of slow-wave sleep appears to be its association with the glymphatic system, which clears [metabolic] waste products and supports memory consolidation,” study coauthor Brandon Westover, MD, PhD, associate professor of neurology at Massachusetts General Hospital/Harvard Medical School, Boston, said in an interview. “It’s also believed to be associated with an accelerated risk for dementia and other cognitive issues.”

Previous work conducted at Johns Hopkins and other institutions confirm Dr. Westerson’s hypothesis. Charlene Gamaldo, MD, medical director of Johns Hopkins Sleep Disorders Center in Baltimore, pointed to other study findings in patients with neurodegenerative disease that have shown a link between predominant habitual sleep positions and dementia, potentially driven by inefficient glymphatic transport. Dr. Gamaldo was not involved in the current study.
 

Threefold acceleration vs. healthy volunteers

“We’ve been grappling with whether people with HIV on ART experience accelerated aging or accentuated aging,” coauthor Shibani Mukerji, MD, PhD, associate director of the neuroinfectious diseases unit at Massachusetts General, said in an interview. “We have yet to have biomarkers to address this question, and most of the tools are limited to invasive or expensive diagnostics. “In general, sleep and its influence on health have been understudied in the HIV population.”

To address this question, the researchers retrospectively examined a Massachusetts General Hospital database of diagnostic sleep study participants from 2008 to 2018, identifying 3,155 healthy, HIV-negative control subjects and 43 HIV-positive participants. Thirty-four (79%) of the HIV-positive participants were men, 30 (70%) were White, and 38 (93%) were virally suppressed at the time of their sleep study. Four patients were taking efavirenz, 13 were taking an integrase strand transfer inhibitor, and all were adherent to antiretroviral therapy (ART) at the time of their sleep study.

None of the HIV-positive participants had a history of secondary brain infection or brain tumor, although one patient had recovered fully from a previous HIV-associated encephalitis.

The study findings, which were published online March 30, 2021, in Sleep, first showed that HIV-positive participants had an average BAI of 3.19 years (standard error of the mean,1.43 years), compared with the control participants, who had an average BAI of –0.16 (SEM, 0.18 years).

These findings held after adjustment for potential confounders (age, sex, race, tobacco use disorder, and alcohol use disorder), yielding a total effect of HIV on BAI of 3.35 years (P < .01).

“Despite being well controlled on ART, HIV-positive individuals who had participated in the sleep studies still had elevated brain age,” said Dr. Westover. “We didn’t have enough information to determine the pathways by which HIV increases the BAI, but chronic inflammation appears to be an important factor.”

The findings also demonstrated that comorbidities accounted for roughly a quarter of the effect of HIV on BAI. However, the lack of statistical significance (in part because of the limited sample size) precluded the ability to determine if treating or preventing them might influence the degree to which HIV affects BAI and, in turn, cognitive decline.
 

HIV, sleep EEG, and brain aging

To estimate the effect of HIV on specific EEG features, the investigators again evaluated the total effect, this time replacing BAI with individual sleep EEG as the primary outcome. Among the 34 EEG features significantly altered by HIV, none were observed in the wake state and three were altered in REM (each associated with reduced delta band power). The rest were distributed in non-REM sleep, most notably in the deepest phase, corresponding to relative reductions in delta wave power.

The study findings build on the investigators’ previous research, which demonstrated an association between greater mean BAI and dementia, psychotic disorders, and anxiety/mood disorders in HIV-negative subjects, all of which correlated to attenuated slow-wave sleep.

More research is needed to determine if BAI, as it relates to sleep EEG, can effectively track the risk for cognitive decline among HIV-positive people, and if certain confounders might attenuate or accelerate this risk.

“While our team has not specifically looked at BAI, the findings in this study seem perfectly in line with what we have found with our own research,” Dr. Gamaldo said in an interview. “Not only have we observed a robust association between minimal cognitive deficits and patients’ sleep complaints (despite being virally controlled), but also, the potential value of measuring the architectural sleep features by ambulatory EEG to identify HIV patients’ vulnerability to cognitive decline.”

“BAI is a physiologic, easily repeatable measurement that can be used to track if an intervention is having a good effect,” Dr. Westover said.

Dr. Mukerji concurred, adding that “having a tool that can be used in resource-challenged settings and also be incorporated into longitudinal studies in a patient population with substantial age-related comorbidities, like HIV, would be really helpful.”

Dr. Westover and Dr. Mukerji disclosed no relevant financial relationships. Dr. Gamaldo is a consultant for Jazz Pharmaceuticals, and has received author royalties from UpToDate and honoraria from Medscape CME for content contribution.

So does “The End of Mental Illness” contain anything of value to the average practicing psychiatrist? (It should be noted that I listened to this as an audiobook and took notes as I listened. This does limit my ability to directly quote portions of the text, but I believe my notes are reliable.)

In 2015-2016, almost 40% of adults and 18.5% of children ages 2 to 19 years in the United States met the definition for obesity—a chronic, relapsing, multifactorial, neurobehavioral disease that results in adverse metabolic, biomechanical, and psychosocial health consequences.^1,2

Tremendous resources have been invested in research, policy development, and public education to try to prevent obesity and its related complications. Despite this, the obesity epidemic has worsened. Here, we explore how to evaluate and treat obese patients in a primary care setting based on the evidence and our experience seeing patients specifically for weight management in a family medicine residency teaching clinic. Pharmacotherapy and surgery, while often helpful, are outside the scope of this article.

It begins withan obesity-friendly office

Patients may have reservations about health care interactions specific to obesity, so it is important to invite them into a setting that facilitates trust and encourages collaboration. Actively engage patients with unhealthy weight by creating an environment where they feel comfortable. Offer wide chairs without armrests, which will easily accommodate patients of all sizes, and ensure that scales have a weight capacity > 400 lb. Communicate a message to patients, via waiting room materials and videos, that focuses on health rather than on weight or body mass index (BMI).

Understand the patient’s goals and challenges

Most (although not all) family physicians will see obese patients in the context of a visit for diabetes, hypertension, or another condition. However, we feel that having visits specifically to address weight in the initial stages of weight management is helpful. The focus of an initial visit should be getting to know how obesity has affected the patient and what his or her motive is in attempting to lose weight. Explore previous attempts at weight loss and establish what the patient’s highest weight has been, as this will impact weight-loss goals. For example, if a patient has weighed > 300 lb all her adult life, it will be extremely difficult to maintain a weight loss of 150 lb.

What else to ask about. Discuss stressors that may be causing increased food intake or poor food choices, including hunger, anger, loneliness, and sleep difficulties. Multidisciplinary care including a psychologist can aid in addressing these issues. Ask patients if they keep a food diary (and if not, recommend that they start), as food diaries are often helpful in elucidating eating and drinking patterns. Determine a patient’s current and past levels of physical activity, as this will guide the fitness goals you develop for him or her.

Screen for psychosocial disorders

As noted earlier, the physical component of obesity is commonly associated with mood disorders such as anxiety and depression.² This requires a multidisciplinary team effort to facilitate healing in the patient struggling with obesity.

Screening for depression and anxiety using standardized tools such as the Patient Health Questionnaire-9 or the Generalized Anxiety Disorder-7 is encouraged in patients who are overweight or obese. Positive screens should be addressed as part of the patient’s treatment plan, as untreated depression and anxiety can inhibit success with weight loss. Be mindful that many medications commonly used to treat these conditions can impair weight loss and even promote weight gain.

Continue to: Don't overlook binge-eating disorders

Don’t overlook binge-eating disorders. Screening specifically for binge-eating disorders is important, given the implications on treatment. The US Department of Veterans Affairs developed a single-item tool for this purpose, the VA Binge Eating Screener. The validated questionnaire asks, “On average, how often have you eaten extremely large amounts of food at one time and felt that your eating was out of control at that time?” Response options are: “Never,” “< 1 time/week,” “1 time/week,” “2-4 times/week,” and “5+ times/week.” A response of ≥ 2 times/week had a sensitivity of 88.9% and specificity of 83.2% for binge-eating disorder.³

For patients who prefer a vegan or vegetarian whole food diet, it is important to note that these diets are generally deficient in vitamin B12 and omega 3 fatty acids, so supplementing these should be considered.

Patients with positive screens should undergo psychotherapy and consider pharmacotherapy with lisdexamfetamine as part of their treatment plan. Caution should be used if recommending intermittent fasting for someone with binge-eating disorder.

Evaluate for underlying causes and assess for comorbidities

Review the patient’s current medication list and history. Many medications can cause weight gain, and weight loss can often be achieved by deprescribing such medications. When feasible, prescribe an alternative medication with a more favorable weight profile. A previous article in The Journal of Family Practice addresses this in more depth.⁴

Laboratory and other testing

Laboratory analysis should primarily be focused on determining treatment alterations specific to underlying pathophysiology. Tests to consider ordering are outlined in the Table. Identification of underlying causes and/or comorbid conditions through such testing can guide medication changes, treatment choices, and diet recommendations.

Diabetes and insulin resistance. The American Diabetes Association recommends screening patients who are overweight or obese and have an additional risk factor for diabetes.⁵ This can be done by obtaining a fasting glucose level, hemoglobin A1C, or a 2-hour oral glucose tolerance test.

Continue to: Since it is known that...

Since it is known that insulin resistance increases the risk for coronary heart disease⁶ and can be treated effectively,⁷ we recommend testing for insulin resistance in patients who do not already have impaired fasting glucose, prediabetes, type 2 diabetes, or impaired glucose tolerance. The homeostatic model assessment for insulin resistance (HOMA-IR)⁸ is a measure of insulin resistance and can be calculated from the fasting insulin and fasting glucose levels. This measure should not be done in isolation, but it can be a useful adjunct in identifying patients with insulin resistance and directing treatment.

If there is evidence of diabetes or insulin resistance, consider treatment with metformin ± initiation of a low-carbohydrate diet.

Hypothyroidism. Consider screening for thyroid dysfunction with a thyroid-stimulating hormone level, if it has not been checked previously.

Renal abnormalities. When serum creatinine levels and glomerular filtration rate indicate chronic kidney disease, consider recommending a protein-restricted diet and adjust medications according to renal dosing protocols, as indicated.

Liver abnormalities, including nonalcoholic fatty liver disease (NAFLD). Monitor aspartate aminotransferase and alanine aminotransferase for resolution of elevations as weight loss is achieved. If abnormalities persist, consider ordering a liver ultrasound. Traditionally, low-calorie diets have been prescribed to treat NAFLD, but evidence shows that low-carbohydrate diets can also be effective.⁹

Continue to: Hypertriglyceridemia and low high-density lipoprotein (HDL) levels

Hypertriglyceridemia and low high-density lipoprotein (HDL) levels. Obtain a lipid panel if one has not been completed within the past several years, as hypertriglyceridemia and low HDL can improve dramatically with specific dietary changes.⁷ Observe trends to assess for resolution of lipid abnormalities as weight loss is achieved.

Gout. Consider checking a uric acid level if you are thinking about recommending a low-carbohydrate diet, particularly in patients with a history of gout, as this may temporarily increase the risk of gout flare.

Hypovitaminosis D. If the patient’s vitamin D level is low, consider appropriate supplementation to support the patient’s overall health. While vitamin D deficiency is common in obesity, the role of supplementation in this population is unclear.

Cardiovascular disease. Consider ordering an electrocardiogram, particularly if you are thinking of prescribing medication therapy. Use caution with initiation of certain medications, such as phentermine or diethylproprion, in the presence of arrhythmias or active cardiovascular disease.

Obstructive sleep apnea. Sleep health is important to address, since obesity is one of the most significant risk factors for obstructive sleep apnea.¹⁰ If your patient is given a diagnosis of OSA following a sleep study, consider treatment with continuous positive airway pressure (CPAP), although there are conflicting studies regarding the effects of CPAP therapy in OSA on weight.^11,12

Continue to: Provide guidance on lifestyle changes

Provide guidance on lifestyle changes

Addressing obesity with patients can be challenging in a busy primary care clinic, but it is imperative to helping patients achieve overall health. Counseling on nutrition and physical activity is an important part of this process.

There is no one-size-fits-all approach to nutrition counseling. Focus on creating individualized plans through which patients can achieve success. Some guidance follows, but also beware of common pitfalls that we have observed in clinical practice which, when addressed, can enable significant weight loss (see “Common pitfalls inhibiting weight loss”).

Choose an approach that works for the patient. Commonly prescribed diets to address obesity include, but are not limited to, Atkins, Dietary Approaches to Stop Hypertension (DASH), Glycemic Index, Mediterranean, Ornish, Paleolithic, Zone, whole food plant-based, and ketogenic. We attempt to engage patients in making the decision on what food choices are appropriate for them considering their food availability, culture, and belief systems. For patients who prefer a vegan or vegetarian whole food diet, it is important to note that these diets are generally deficient in vitamin B12 and omega 3 fatty acids, so supplementing these should be considered.

We recommend that patients focus on eliminating sweetened beverages, such as soft drinks, sports drinks, energy drinks, vitamin water, sweet tea, chocolate milk, and Frappuccinos.

Rather than focus on a specific diet, which may not be sustainable long term, encourage healthy eating habits. Low-­carbohydrate diets have been shown to promote greater weight loss compared to low-fat diets.^13,14 Low-calorie diets can also be quite effective in promoting short-term weight loss. In our clinic, when weight loss is the primary goal, patients are typically encouraged to focus on either calorie or carbohydrate restriction in the initial stages of weight loss.

Eliminate sugar and refined carbohydrates. While rigorous mortality data are not available, more recent trials have demonstrated significant improvements in atherosclerotic cardiovascular disease risk markers, including weight reduction and diabetes reversal, when following a diet that markedly decreases carbohydrate intake, especially sugar and refined carbohydrates.^7,14-17

Continue to: We recommend that patients focus...

We recommend that patients focus on eliminating sweetened beverages, such as soft drinks, sports drinks, energy drinks, vitamin water, sweet tea, chocolate milk, and Frappuccinos. We also recommend substantially limiting or eliminating fruit juices and fruit smoothies due to their high sugar content. For example, 8 oz of orange juice contains 26 g of carbohydrates, which is almost as much as 8 oz of soda.

Compared with eating whole fruit, consuming fruit juice has demonstrated a small amount of weight gain in young children and adults.^18,19 It also has shown a higher insulin response compared with eating the same amount of carbohydrates in whole fruit.²⁰ Better options to drink include water, unsweetened tea, and black coffee. Also, avoid ultra-processed carbohydrates from foods such as breads, cereals, and pastries, as they have similar effects on blood glucose when compared to sugar.²¹

Greatly restrict highly processed foods. The evidence suggests that the availability of processed food is associated with increasing obesity.²² Simple advice to offer your patients is to encourage them to shop the perimeter of the grocery store, where fresh produce, meat, and dairy products are primarily located, and avoid the inner aisles, which contain primarily processed foods. Choosing food items with 5 or fewer ingredients is a starting point when teaching patients to read labels.

Consider limiting saturated fats. In 1977, the Dietary Guidelines for Americans recommended that Americans eat no more than 30% of total energy intake from fat and less than 10% of total energy intake from saturated fat; however, no randomized controlled trials had been done that supported this recommendation and epidemiologic data supporting it were weak.²³

The 2015 Dietary Guidelines continue to recommend limiting total energy intake from saturated fats.²⁴ While there may be a small decrease in cardiovascular risk with a reduction of saturated fat intake and replacement with unsaturated fats, no overall mortality benefit has been demonstrated.^24,25 More research is needed in this area to guide patients in decisions regarding consumption of saturated fats and what types of unsaturated fats are best for their health.

Continue to: Eat only 3 meals per day

Eat only 3 meals per day, but aim for fewer than that. The prescription of fasting is a modality that can be used for weight loss and improved health. Fasting has been a prescribed healing practice for thousands of years.²⁶ It is a practice that virtually every major religion in the world embraces. Studies have demonstrated fasting to be safe and effective in the setting of obesity without significant comorbidities, and it may promote weight loss and metabolic health.^26-29

There are multiple types of intermittent fasting. A practical way for patients to start is by restricting the number of hours in which they eat or drink calorie-containing beverages to 8 hours per day. In our experience, this regimen is easier for most patients to follow than alternate-day or other longer fasts. While there has been caution in the prescription of intermittent fasting due to concerns about causing eating disorders, a recent small study did not demonstrate increased risk of eating disorders with daily intermittent fasting.³⁰

Participate in healthy exercise. Nonpharmacologic office-based strategies for treating obesity have generally focused on increasing exercise and decreasing caloric intake.³¹ While exercise has significant health benefits, including preventing weight regain, evidence does not support monotherapy with exercise as an effective long-term weight-loss strategy.³² There are no studies available that adequately support prescribing an exact dose of exercise.³³ Generally, less than 150 minutes of exercise per week is not effective and more than that does have a dose-related response.³³

Follow up to help patients stay on target

There is no ideal interval for follow-up visits. However, frequent visits—anywhere from weekly to monthly—in the initial stages of weight loss increase the patient’s sense of accountability and, in our experience, seem to be helpful.

Patients may also choose to track their progress by weighing themselves regularly. A small study published in the International Journal of Obesity found that patients who weighed themselves daily had greater and more sustained weight loss than those who didn’t.³⁴ But the decision of whether to weigh one’s self at home should be individualized for each patient.

In 2015-2016, almost 40% of adults and 18.5% of children ages 2 to 19 years in the United States met the definition for obesity—a chronic, relapsing, multifactorial, neurobehavioral disease that results in adverse metabolic, biomechanical, and psychosocial health consequences.^1,2

Tremendous resources have been invested in research, policy development, and public education to try to prevent obesity and its related complications. Despite this, the obesity epidemic has worsened. Here, we explore how to evaluate and treat obese patients in a primary care setting based on the evidence and our experience seeing patients specifically for weight management in a family medicine residency teaching clinic. Pharmacotherapy and surgery, while often helpful, are outside the scope of this article.

It begins withan obesity-friendly office

Patients may have reservations about health care interactions specific to obesity, so it is important to invite them into a setting that facilitates trust and encourages collaboration. Actively engage patients with unhealthy weight by creating an environment where they feel comfortable. Offer wide chairs without armrests, which will easily accommodate patients of all sizes, and ensure that scales have a weight capacity > 400 lb. Communicate a message to patients, via waiting room materials and videos, that focuses on health rather than on weight or body mass index (BMI).

Understand the patient’s goals and challenges

Most (although not all) family physicians will see obese patients in the context of a visit for diabetes, hypertension, or another condition. However, we feel that having visits specifically to address weight in the initial stages of weight management is helpful. The focus of an initial visit should be getting to know how obesity has affected the patient and what his or her motive is in attempting to lose weight. Explore previous attempts at weight loss and establish what the patient’s highest weight has been, as this will impact weight-loss goals. For example, if a patient has weighed > 300 lb all her adult life, it will be extremely difficult to maintain a weight loss of 150 lb.

What else to ask about. Discuss stressors that may be causing increased food intake or poor food choices, including hunger, anger, loneliness, and sleep difficulties. Multidisciplinary care including a psychologist can aid in addressing these issues. Ask patients if they keep a food diary (and if not, recommend that they start), as food diaries are often helpful in elucidating eating and drinking patterns. Determine a patient’s current and past levels of physical activity, as this will guide the fitness goals you develop for him or her.

Screen for psychosocial disorders

As noted earlier, the physical component of obesity is commonly associated with mood disorders such as anxiety and depression.² This requires a multidisciplinary team effort to facilitate healing in the patient struggling with obesity.

Screening for depression and anxiety using standardized tools such as the Patient Health Questionnaire-9 or the Generalized Anxiety Disorder-7 is encouraged in patients who are overweight or obese. Positive screens should be addressed as part of the patient’s treatment plan, as untreated depression and anxiety can inhibit success with weight loss. Be mindful that many medications commonly used to treat these conditions can impair weight loss and even promote weight gain.

Continue to: Don't overlook binge-eating disorders

Don’t overlook binge-eating disorders. Screening specifically for binge-eating disorders is important, given the implications on treatment. The US Department of Veterans Affairs developed a single-item tool for this purpose, the VA Binge Eating Screener. The validated questionnaire asks, “On average, how often have you eaten extremely large amounts of food at one time and felt that your eating was out of control at that time?” Response options are: “Never,” “< 1 time/week,” “1 time/week,” “2-4 times/week,” and “5+ times/week.” A response of ≥ 2 times/week had a sensitivity of 88.9% and specificity of 83.2% for binge-eating disorder.³

For patients who prefer a vegan or vegetarian whole food diet, it is important to note that these diets are generally deficient in vitamin B12 and omega 3 fatty acids, so supplementing these should be considered.

Patients with positive screens should undergo psychotherapy and consider pharmacotherapy with lisdexamfetamine as part of their treatment plan. Caution should be used if recommending intermittent fasting for someone with binge-eating disorder.

Evaluate for underlying causes and assess for comorbidities

Review the patient’s current medication list and history. Many medications can cause weight gain, and weight loss can often be achieved by deprescribing such medications. When feasible, prescribe an alternative medication with a more favorable weight profile. A previous article in The Journal of Family Practice addresses this in more depth.⁴

Laboratory and other testing

Laboratory analysis should primarily be focused on determining treatment alterations specific to underlying pathophysiology. Tests to consider ordering are outlined in the Table. Identification of underlying causes and/or comorbid conditions through such testing can guide medication changes, treatment choices, and diet recommendations.

Diabetes and insulin resistance. The American Diabetes Association recommends screening patients who are overweight or obese and have an additional risk factor for diabetes.⁵ This can be done by obtaining a fasting glucose level, hemoglobin A1C, or a 2-hour oral glucose tolerance test.

Continue to: Since it is known that...

Since it is known that insulin resistance increases the risk for coronary heart disease⁶ and can be treated effectively,⁷ we recommend testing for insulin resistance in patients who do not already have impaired fasting glucose, prediabetes, type 2 diabetes, or impaired glucose tolerance. The homeostatic model assessment for insulin resistance (HOMA-IR)⁸ is a measure of insulin resistance and can be calculated from the fasting insulin and fasting glucose levels. This measure should not be done in isolation, but it can be a useful adjunct in identifying patients with insulin resistance and directing treatment.

If there is evidence of diabetes or insulin resistance, consider treatment with metformin ± initiation of a low-carbohydrate diet.

Hypothyroidism. Consider screening for thyroid dysfunction with a thyroid-stimulating hormone level, if it has not been checked previously.

Renal abnormalities. When serum creatinine levels and glomerular filtration rate indicate chronic kidney disease, consider recommending a protein-restricted diet and adjust medications according to renal dosing protocols, as indicated.

Liver abnormalities, including nonalcoholic fatty liver disease (NAFLD). Monitor aspartate aminotransferase and alanine aminotransferase for resolution of elevations as weight loss is achieved. If abnormalities persist, consider ordering a liver ultrasound. Traditionally, low-calorie diets have been prescribed to treat NAFLD, but evidence shows that low-carbohydrate diets can also be effective.⁹

Continue to: Hypertriglyceridemia and low high-density lipoprotein (HDL) levels

Hypertriglyceridemia and low high-density lipoprotein (HDL) levels. Obtain a lipid panel if one has not been completed within the past several years, as hypertriglyceridemia and low HDL can improve dramatically with specific dietary changes.⁷ Observe trends to assess for resolution of lipid abnormalities as weight loss is achieved.

Gout. Consider checking a uric acid level if you are thinking about recommending a low-carbohydrate diet, particularly in patients with a history of gout, as this may temporarily increase the risk of gout flare.

Hypovitaminosis D. If the patient’s vitamin D level is low, consider appropriate supplementation to support the patient’s overall health. While vitamin D deficiency is common in obesity, the role of supplementation in this population is unclear.

Cardiovascular disease. Consider ordering an electrocardiogram, particularly if you are thinking of prescribing medication therapy. Use caution with initiation of certain medications, such as phentermine or diethylproprion, in the presence of arrhythmias or active cardiovascular disease.

Obstructive sleep apnea. Sleep health is important to address, since obesity is one of the most significant risk factors for obstructive sleep apnea.¹⁰ If your patient is given a diagnosis of OSA following a sleep study, consider treatment with continuous positive airway pressure (CPAP), although there are conflicting studies regarding the effects of CPAP therapy in OSA on weight.^11,12

Provide guidance on lifestyle changes

Addressing obesity with patients can be challenging in a busy primary care clinic, but it is imperative to helping patients achieve overall health. Counseling on nutrition and physical activity is an important part of this process.

There is no one-size-fits-all approach to nutrition counseling. Focus on creating individualized plans through which patients can achieve success. Some guidance follows, but also beware of common pitfalls that we have observed in clinical practice which, when addressed, can enable significant weight loss (see “Common pitfalls inhibiting weight loss”).

Choose an approach that works for the patient. Commonly prescribed diets to address obesity include, but are not limited to, Atkins, Dietary Approaches to Stop Hypertension (DASH), Glycemic Index, Mediterranean, Ornish, Paleolithic, Zone, whole food plant-based, and ketogenic. We attempt to engage patients in making the decision on what food choices are appropriate for them considering their food availability, culture, and belief systems. For patients who prefer a vegan or vegetarian whole food diet, it is important to note that these diets are generally deficient in vitamin B12 and omega 3 fatty acids, so supplementing these should be considered.

We recommend that patients focus on eliminating sweetened beverages, such as soft drinks, sports drinks, energy drinks, vitamin water, sweet tea, chocolate milk, and Frappuccinos.

Rather than focus on a specific diet, which may not be sustainable long term, encourage healthy eating habits. Low-­carbohydrate diets have been shown to promote greater weight loss compared to low-fat diets.^13,14 Low-calorie diets can also be quite effective in promoting short-term weight loss. In our clinic, when weight loss is the primary goal, patients are typically encouraged to focus on either calorie or carbohydrate restriction in the initial stages of weight loss.

Eliminate sugar and refined carbohydrates. While rigorous mortality data are not available, more recent trials have demonstrated significant improvements in atherosclerotic cardiovascular disease risk markers, including weight reduction and diabetes reversal, when following a diet that markedly decreases carbohydrate intake, especially sugar and refined carbohydrates.^7,14-17

Continue to: We recommend that patients focus...

We recommend that patients focus on eliminating sweetened beverages, such as soft drinks, sports drinks, energy drinks, vitamin water, sweet tea, chocolate milk, and Frappuccinos. We also recommend substantially limiting or eliminating fruit juices and fruit smoothies due to their high sugar content. For example, 8 oz of orange juice contains 26 g of carbohydrates, which is almost as much as 8 oz of soda.

Compared with eating whole fruit, consuming fruit juice has demonstrated a small amount of weight gain in young children and adults.^18,19 It also has shown a higher insulin response compared with eating the same amount of carbohydrates in whole fruit.²⁰ Better options to drink include water, unsweetened tea, and black coffee. Also, avoid ultra-processed carbohydrates from foods such as breads, cereals, and pastries, as they have similar effects on blood glucose when compared to sugar.²¹

Greatly restrict highly processed foods. The evidence suggests that the availability of processed food is associated with increasing obesity.²² Simple advice to offer your patients is to encourage them to shop the perimeter of the grocery store, where fresh produce, meat, and dairy products are primarily located, and avoid the inner aisles, which contain primarily processed foods. Choosing food items with 5 or fewer ingredients is a starting point when teaching patients to read labels.

Consider limiting saturated fats. In 1977, the Dietary Guidelines for Americans recommended that Americans eat no more than 30% of total energy intake from fat and less than 10% of total energy intake from saturated fat; however, no randomized controlled trials had been done that supported this recommendation and epidemiologic data supporting it were weak.²³

The 2015 Dietary Guidelines continue to recommend limiting total energy intake from saturated fats.²⁴ While there may be a small decrease in cardiovascular risk with a reduction of saturated fat intake and replacement with unsaturated fats, no overall mortality benefit has been demonstrated.^24,25 More research is needed in this area to guide patients in decisions regarding consumption of saturated fats and what types of unsaturated fats are best for their health.

Continue to: Eat only 3 meals per day

Eat only 3 meals per day, but aim for fewer than that. The prescription of fasting is a modality that can be used for weight loss and improved health. Fasting has been a prescribed healing practice for thousands of years.²⁶ It is a practice that virtually every major religion in the world embraces. Studies have demonstrated fasting to be safe and effective in the setting of obesity without significant comorbidities, and it may promote weight loss and metabolic health.^26-29

There are multiple types of intermittent fasting. A practical way for patients to start is by restricting the number of hours in which they eat or drink calorie-containing beverages to 8 hours per day. In our experience, this regimen is easier for most patients to follow than alternate-day or other longer fasts. While there has been caution in the prescription of intermittent fasting due to concerns about causing eating disorders, a recent small study did not demonstrate increased risk of eating disorders with daily intermittent fasting.³⁰

Working night shifts has been associated with an increased risk for certain cancers, as well as other health disorders. Indeed, the World Health Organization’s International Agency for Research on Cancer (IARC) has classified night shift work as “probably carcinogenic to humans.”

But why night shift should elevate the risk for cancer has been unclear.

A new study shows that a simulated night shift schedule significantly altered the normal circadian rhythmicity of genes that are involved in cancer hallmark pathways. It also found that this circadian misalignment caused circadian dysregulation of genes involved in key DNA repair pathways.

“Taken together, these findings suggest that night shift schedules throw off the timing of expression of cancer-related genes in a way that reduces the effectiveness of the body’s DNA repair processes when they are most needed,” said co-corresponding author Jason McDermott, a computational scientist with the Pacific Northwest National Laboratory’s biological sciences division in Richland, Wash.

The study was published online in the Journal of Pineal Research.
 

Study conducted among volunteers 

The study was carried out among healthy volunteers who were subjected to simulated night shift or day shift schedules.

The cohort comprised 14 adults between the ages of 22 and 34 years who had normal nighttime sleep schedules. They were randomly assigned (seven in each group) to a simulated day shift schedule that involved 3 days of daytime wakefulness (6 a.m.-10 p.m.), or a simulated night shift schedule involving 3 days of nighttime wakefulness (6 p.m.-10 a.m.).

After the 3 days of simulated shift work, all participants were then kept in a constant routine protocol (used to study humans’ internally generated biological rhythms independent of any external influences). As part of the protocol, they were kept awake for 24 hours in a semi-reclined posture under laboratory conditions with constant light exposure and room temperature and evenly distributed food intake (hourly isocaloric snacks).

Blood samples were collected at 3-hour intervals and used for leukocyte transcriptome analysis and DNA damage assessment.

The authors found that the circadian expression of canonical clock genes was substantially altered by the simulated night shift schedule vs. the day shift schedule. Four genes (CRY1, CRY2, PER2, and NR1D2) lost their normal day-shift rhythmicity following the night shift schedule, and NPAS2 gene expression was not rhythmic during the day shift but exhibited circadian rhythmicity in the simulated night shift condition. Three other genes (NR1D1, PER3, and DBP) were significantly rhythmic during both shifts.

The team also looked at the effect of night shift on circadian rhythmicity in cancer hallmark genes, using a panel of 726 genes. The analysis showed that:

• 257 (35.4%) were rhythmic after at least one of the two simulated shift work conditions.
• 113 (15.6%) were rhythmic in day shift only.
• 96 (13.2%) were rhythmic during night shift only.
• 48 (6.6%) were rhythmic during both shifts.

A subset of 10 (1.4%) genes exhibited a significant phase advance (3.7 to 8.3 hours) or phase delay (2.8 to 7.0 hours) during the night shift vs. the day shift.

Thus, the authors concluded, shift work caused significant disturbances in the rhythmicity of gene expression in cancer hallmark pathways.

Findings also showed that night shift work increases endogenous and exogenous DNA damage. Endogenous DNA damage was generally higher after the night shift compared to the day shift, and across the 24-hour constant routine the percentage of cells with BRCA1 and g H2AX foci was significantly higher for night shift.
 

Next steps

The team said that the next step is to conduct the same experiment with real-world shift workers who have been consistently on day or night shifts for many years to determine whether in night workers the unrepaired DNA damage builds up over time, which could ultimately increase the risk for cancer.

If what happens in real-world shift workers is consistent with the current findings, this work could eventually be used to develop prevention strategies and drugs that could address the mistiming of DNA repair processes, they suggested.  

“Night shift workers face considerable health disparities, ranging from increased risks of metabolic and cardiovascular disease to mental health disorders and cancer,” co-senior author Hans Van Dongen, PhD, a professor at Washington State University in Pullman and director of the WSU Sleep and Performance Research Center, Spokane, said in a statement. “It is high time that we find diagnosis and treatment solutions for this underserved group of essential workers so that the medical community can address their unique health challenges.”

The study was supported by start-up funds from Washington State University and a Center for Human Health and the Environment grant from North Carolina State University, and in part by the United States Army Medical Research and Development Command, the National Institutes of Health, CDMRP (Congressionally Directed Medical Research Programs) Peer Reviewed Cancer Research Program award, and the BRAVE investment.

After the 3 days of simulated shift work, all participants were then kept in a constant routine protocol (used to study humans’ internally generated biological rhythms independent of any external influences). As part of the protocol, they were kept awake for 24 hours in a semi-reclined posture under laboratory conditions with constant light exposure and room temperature and evenly distributed food intake (hourly isocaloric snacks).

Blood samples were collected at 3-hour intervals and used for leukocyte transcriptome analysis and DNA damage assessment.

The authors found that the circadian expression of canonical clock genes was substantially altered by the simulated night shift schedule vs. the day shift schedule. Four genes (CRY1, CRY2, PER2, and NR1D2) lost their normal day-shift rhythmicity following the night shift schedule, and NPAS2 gene expression was not rhythmic during the day shift but exhibited circadian rhythmicity in the simulated night shift condition. Three other genes (NR1D1, PER3, and DBP) were significantly rhythmic during both shifts.

The team also looked at the effect of night shift on circadian rhythmicity in cancer hallmark genes, using a panel of 726 genes. The analysis showed that:

• 257 (35.4%) were rhythmic after at least one of the two simulated shift work conditions.
• 113 (15.6%) were rhythmic in day shift only.
• 96 (13.2%) were rhythmic during night shift only.
• 48 (6.6%) were rhythmic during both shifts.

A subset of 10 (1.4%) genes exhibited a significant phase advance (3.7 to 8.3 hours) or phase delay (2.8 to 7.0 hours) during the night shift vs. the day shift.

Thus, the authors concluded, shift work caused significant disturbances in the rhythmicity of gene expression in cancer hallmark pathways.

Findings also showed that night shift work increases endogenous and exogenous DNA damage. Endogenous DNA damage was generally higher after the night shift compared to the day shift, and across the 24-hour constant routine the percentage of cells with BRCA1 and g H2AX foci was significantly higher for night shift.
 

Next steps

The team said that the next step is to conduct the same experiment with real-world shift workers who have been consistently on day or night shifts for many years to determine whether in night workers the unrepaired DNA damage builds up over time, which could ultimately increase the risk for cancer.

If what happens in real-world shift workers is consistent with the current findings, this work could eventually be used to develop prevention strategies and drugs that could address the mistiming of DNA repair processes, they suggested.  

“Night shift workers face considerable health disparities, ranging from increased risks of metabolic and cardiovascular disease to mental health disorders and cancer,” co-senior author Hans Van Dongen, PhD, a professor at Washington State University in Pullman and director of the WSU Sleep and Performance Research Center, Spokane, said in a statement. “It is high time that we find diagnosis and treatment solutions for this underserved group of essential workers so that the medical community can address their unique health challenges.”

The study was supported by start-up funds from Washington State University and a Center for Human Health and the Environment grant from North Carolina State University, and in part by the United States Army Medical Research and Development Command, the National Institutes of Health, CDMRP (Congressionally Directed Medical Research Programs) Peer Reviewed Cancer Research Program award, and the BRAVE investment.

The authors have disclosed no relevant financial relationships.

Working night shifts has been associated with an increased risk for certain cancers, as well as other health disorders. Indeed, the World Health Organization’s International Agency for Research on Cancer (IARC) has classified night shift work as “probably carcinogenic to humans.”

But why night shift should elevate the risk for cancer has been unclear.

A new study shows that a simulated night shift schedule significantly altered the normal circadian rhythmicity of genes that are involved in cancer hallmark pathways. It also found that this circadian misalignment caused circadian dysregulation of genes involved in key DNA repair pathways.

“Taken together, these findings suggest that night shift schedules throw off the timing of expression of cancer-related genes in a way that reduces the effectiveness of the body’s DNA repair processes when they are most needed,” said co-corresponding author Jason McDermott, a computational scientist with the Pacific Northwest National Laboratory’s biological sciences division in Richland, Wash.

The study was published online in the Journal of Pineal Research.
 

Study conducted among volunteers 

The study was carried out among healthy volunteers who were subjected to simulated night shift or day shift schedules.

The cohort comprised 14 adults between the ages of 22 and 34 years who had normal nighttime sleep schedules. They were randomly assigned (seven in each group) to a simulated day shift schedule that involved 3 days of daytime wakefulness (6 a.m.-10 p.m.), or a simulated night shift schedule involving 3 days of nighttime wakefulness (6 p.m.-10 a.m.).

After the 3 days of simulated shift work, all participants were then kept in a constant routine protocol (used to study humans’ internally generated biological rhythms independent of any external influences). As part of the protocol, they were kept awake for 24 hours in a semi-reclined posture under laboratory conditions with constant light exposure and room temperature and evenly distributed food intake (hourly isocaloric snacks).

COVID-19 survivors face a sharply elevated risk of developing psychiatric or neurologic disorders in the 6 months after they contract the virus – a danger that mounts with symptom severity, new research shows.
 

In what is purported to be the largest study of its kind to date, results showed that among 236,379 COVID-19 patients, one-third were diagnosed with at least 1 of 14 psychiatric or neurologic disorders within a 6-month span.

The rate of illnesses, which ranged from depression to stroke, rose sharply among those with COVID-19 symptoms acute enough to require hospitalization.  

“If we look at patients who were hospitalized, that rate increased to 39%, and then increased to about just under 1 in 2 patients who needed ICU admission at the time of the COVID-19 diagnosis,” Maxime Taquet, PhD, University of Oxford (England) department of psychiatry, said at a media briefing.

Incidence jumps to almost two-thirds in patients with encephalopathy at the time of COVID-19 diagnosis, he added.

The study, which examined the brain health of 236,379 survivors of COVID-19 via a U.S. database of 81 million electronic health records, was published online April 6 in The Lancet Psychiatry.
 

High rate of neurologic, psychiatric disorders

The research team looked at the first-time diagnosis or recurrence of 14 neurologic and psychiatric outcomes in patients with confirmed SARS-CoV-2 infections. They also compared the brain health of this cohort with a control group of those with influenza or with non–COVID-19 respiratory infections over the same period. 

All study participants were older than 10 years, diagnosed with COVID-19 on or after Jan. 20, 2020, and still alive as of Dec. 13, 2020.

The psychiatric and neurologic conditions examined included intracranial hemorrhage; ischemic stroke; parkinsonism; Guillain-Barré syndrome; nerve, nerve root and plexus disorders; myoneural junction and muscle disease; encephalitis; dementia; psychotic, mood, and anxiety disorders; substance use disorder; and insomnia.

The investigators used hospitalization, intensive care admissions, and encephalopathy as an indication of the severity of COVID-19 symptoms.

The study benchmarked the primary cohort with four populations of patients diagnosed in the same period with nonrespiratory illnesses, including skin infection, urolithiasis, bone fractures, and pulmonary embolisms.

Results showed that substantially more COVID-19 patients were diagnosed with a neurologic or psychiatric disorder compared with those with other respiratory illnesses.

“On average, in terms of the relative numbers, there was a 44% increased risk of having a neurological or psychiatric diagnosis after COVID-19 than after the flu and a 16% increased risk compared to other respiratory tract infections,” Dr. Taquet told reporters.

Health services should be prepared for an increase in psychiatric and neurologic issues in the months to come, he said, adding that further investigations are needed into why, and how, the coronavirus affects brain health.
 

Largest study to date

Although previous research suggests a link between the two, this is the largest study of its kind, examines a wider range of neurologic outcomes, and spans the longest time frame to date, said study coinvestigator Paul Harrison, BM BCh, associate head of the University of Oxford department of psychiatry.

There was a lower incidence of mood and anxiety disorders vs. neurologic disorders in patients with severe COVID-19 symptoms, a finding that Dr. Harrison said may indicate pandemic-related psychological stress is driving these disorders vs. biological factors.

“This paper follows up on an earlier study we did where we found much the same association, and our view is that a lot of the mental health consequences of COVID are … to do with the stress of knowing that one has had COVID and all the implications that go with that, rather than its being a direct effect, for example, of the virus on the brain, or of the immune response to the virus on the brain,” he added.

In contrast, neurologic diagnoses were more likely to be “mediated by some direct consequence of the COVID infection,” he added.

Psychosis and dementia, for instance, were less frequent in the overall COVID-19 population but became much more frequent among those with severe symptoms. The research team said these findings, along with those related to the incidence of ischemic stroke, were “concerning.”

“We found that 1 in 50 patients with COVID-19 go on to have an ischemic stroke in the 6 months after the COVID-19 illness,” Dr. Taquet told reporters. “And that rate increased to 1 in 11 patients if we look at patients with encephalopathy at the time of the COVID-19 diagnosis.”

Rates of brain hemorrhages also rose sharply among those with acute symptoms. Just over 1 in 200 total COVID-19 patients were diagnosed with this neurological condition, but that jumped to 1 in 25 of those who experienced encephalopathy at the time of their COVID-19 diagnosis.
 

Need for replication

Study coauthor Masud Husain, PhD, of University of Oxford’s cognitive neurology department, told reporters that while there is evidence from other neurologic studies that the virus can access the brain, there has been little sign the neurons themselves are affected.

“There isn’t much evidence that the virus itself attacks neurons in the brain, but it can cause inflammation, and it can activate inflammatory cells in the brain,” he said.

“And those effects are probably very important in some of the biological effects on the brain. In addition, of course, we know that the virus can change clotting and the likelihood of thrombosis in the blood, and those effects can also impact upon the brain,” he added.

Dr. Harrison said it would be helpful to replicate the results garnered from the U.S. database in other populations.

“It goes without saying that replication of these results with other electronic health records and in other countries is a priority,” he said, adding that investigations are essential into how and why the virus affects brain health.

Dr. Harrison cited a U.K. Research and Innovation–funded study called COVID CNS that will follow patients with neurologic and/or psychiatric issues during acute COVID-19 in hopes of exploring possible causes.
 

Beyond a reasonable doubt

Commenting on the findings, Sir Simon Wessely, MD, Regius chair of psychiatry, King’s College London, said in a release: “This is a very important paper. It confirms beyond any reasonable doubt that COVID-19 affects both brain and mind in equal measure.”

Some of these effects, including stroke and anxiety disorders, were already known, but others such as dementia and psychosis were less well known, he added. 

“What is very new is the comparisons with all respiratory viruses or influenza, which suggests that these increases are specifically related to COVID-19, and not a general impact of viral infection,” Dr. Wessely said. “In general, the worse the illness, the greater the neurological or psychiatric outcomes, which is perhaps not surprising.    

“The worst outcomes were in those with encephalopathy – inflammation of the brain – again, not surprising. The association with dementia was, however, small and might reflect diagnostic issues, whilst so far there doesn’t seem early evidence of a link with parkinsonism, which was a major factor after the great Spanish Flu pandemic, although the authors caution that it is too early to rule this out.”

In 1967, when the United Nations Convention on Drugs classified psychedelics as schedule I substances, it effectively ended research into these agents as potential therapeutics for psychiatric disorders.

Psychedelics induce altered states of perception. They bind to the 5-hydroxytryptamine 2A (5-HT2A) receptor and include psilocybin, which is derived from “magic mushrooms”; N,N-dimethyltryptamine (DMT), a component of ayahuasca and mescaline (peyote cactus); and the synthesized compound D-lysergic acid diethylamide (LSD). Other agents, such as ketamine and 3,4-methylenedioxymethamphetamine (MDMA), also known as ecstasy, are sometimes considered psychedelics as well.

Before they were classified as schedule I agents, psychedelics had been shown to be particularly beneficial for patients with treatment-resistant conditions, including depression and posttraumatic stress disorder (PTSD), especially when administered in a supportive, therapeutic setting.

Now, after a hiatus of almost 50 years, there is renewed global interest in the scientific investigation of psychedelics. The attention was spurred in part by several exploratory studies of DMT in humans conducted in the 1990s by Rick Strassman, MD, and colleagues at the University of New Mexico, Albuquerque.

Around the same time, Franz X. Vollenweider, MD, and colleagues at the University of Zürich began researching psilocybin and its effects on human behavior. However, it was a 2006 study of psilocybin by a team of researchers at Johns Hopkins University, Baltimore, that is widely cited as a catalyst for the current renaissance in psychedelic research.

To provide a broad-based, international perspective on these agents, including their current legal status and indications, treatment regimens, safety, efficacy, and future considerations, this news organization interviewed nine expert researchers from around the globe.
 

Global legal status

In most, if not all, countries, it is still illegal to prescribe psychedelics in other than a research setting.

In the United States, classic psychedelics remain schedule I substances and therefore are unavailable for clinical use. They can be used in research, but only with approval from the Food and Drug Administration under licensure from the Drug Enforcement Administration.

France lists all synthetic hallucinogens and hallucinogenic mushrooms as narcotic. As a result, possession, use, transportation, and collection are subject to criminal sanctions.

In France, NMDA antagonists such as ketamine and nitrous oxide are regarded as psychedelic molecules and can be used off label for various conditions or as part of research protocols authorized by the French public health code.

Although psychedelics are illegal under Mexican law, they are commonly used in indigenous communities as part of traditional rituals.

“The line between traditional consumption and psychedelic tourism is very thin,” José J. Mendoza Velásquez, MD, professor in the department of mental health, National Autonomous University of Mexico, Mexico City, said in an interview.

Psychedelics also are illegal in the United Kingdom, although government agencies have recently allowed research groups to investigate them. Psychedelics cannot be prescribed in Germany, Spain, or Italy. However, investigators in these countries can request permission from regulatory agencies to conduct research.

Brazil allows psychedelic substances to be researched, particularly ayahuasca, which has long traditional and religious roots in the country.

However, as in other countries, none of the classic psychedelics is regulated for therapeutic use in Brazil. It is widely expected that the Brazilian government will approve MDMA sometime in 2024 for use in the treatment of PTSD.
 

Potential indications

Psychedelics are currently under investigation as potential treatments for major depression, treatment-resistant depression, PTSD, pain management, and anorexia, among other conditions.

In France, Florian Ferreri, MD, PhD, at Hospital Saint-Antoine, Paris, is researching ketamine for treatment of patients with suicidal crisis/ideation and treatment-resistant depression.

In the United Kingdom, David Nutt, FMedSci, Edmond J. Safra Professor of Neuropsychopharmacology at Imperial College London, and his team have conducted studies of the use of psychedelics in conjunction with psychological support for patients with treatment-resistant depression, and they are currently exploring their use in the treatment of anorexia and various pain syndromes.

In Germany, Gerhard Gründer, MD, professor of psychiatry at the Central Institute of Mental Health, in Mannheim, noted that a study of psilocybin for treatment-resistant depression will launch sometime in 2021. In Italy, current research is focusing on MDMA and ketamine in the laboratory environment and in animal models for treating depression and drug abuse.

Researcher Helen Dolengevich-Segal, MD, a psychiatrist at Hospital Universitario del Henares, Madrid, noted that although research on esketamine for the treatment of severe depressive disorder with suicidal thoughts is underway, there is very limited published research from that country into the use of classic psychedelics for various psychiatric disorders, given their current illegal status.

Mexico’s Dr. Velásquez noted that although he is prohibited from prescribing psychedelics, he does have patients who take the drugs to augment medical treatment. For instance, he said, his patients frequently use psilocybin to help with severe depression, pain, and insomnia.
 

Environment is key

Most researchers agree that for psychedelics to be safe and effective, patient education and administration in a controlled environment by experienced clinicians are key to successful treatment.

Roland R. Griffiths, PhD, director of the Center for Psychedelic and Consciousness Research at Johns Hopkins, said that ongoing U.S. psilocybin research – primarily in major depressive disorder and psychological distress associated with life-threatening illness, drug addiction, anorexia nervosa, obsessive-compulsive disorder, and headache – generally includes one or two treatment sessions, each of which lasts 6-8 hours.

Such sessions typically involve oral administration of a moderately high dose of a psychedelic under what he characterizes as “psychologically supported conditions.”

For Dr. Griffiths, there are serious potential risks associated with the use of psilocybin and other psychedelics outside such environments.

“When taken in uncontrolled conditions, classic psychedelics can produce confusion and disorientation resulting in behavior dangerous to the participant and others, including life-threatening risk,” he said.

Dr. Gründer agreed.

“At the moment, I cannot imagine that you would go to the pharmacy with a prescription for psilocybin and get yourself a pill and then take it in a quiet little room,” he said. Dr. Dolengevich-Segal and Dr. Velásquez echoed these sentiments, noting the optimal location for administration is one that is quiet and secure and where patients feel safe.

Luís Fernando Tófoli, MD, PhD, professor of medical psychology and psychiatry at the University of Campinas, and Eduardo Schenberg, PhD, founder and CEO of Instituto Phaneros in São Paulo, Brazil, said more research is needed to determine the optimal therapeutic environment for individual agents.

“Most studies have a low number of participants (around 20 or 30), especially in neuroimaging, with high unblinding rates,” Dr. Schenberg said. “Therefore, novel methodological approaches are also necessary, as these substances do not easily fit into the traditional pharmacology epistemic model.”
 

Risks, abuse potential

The abuse potential of psychedelics is an ongoing concern for the public, researchers, and regulators, but the consensus among nearly all of these experts is that when administered by medical professionals in controlled settings, these drugs are associated with extremely low risk.

It is recreational use that presents an abuse concern, said Dr. Ferreri, but with the low doses used in psychiatry, the risk is “very limited or even nonexistent.”

Dr. Nutt said the abuse potential of psychedelics is so low that they can be used to treat addiction.

“Functionally, psychedelics are antiaddictive,” Dr. Nutt said. “The fact is, if you take them repeatedly, you develop tolerance, and the effect disappears. You can’t overcome it. But everyone believes they’re addictive because they’re scheduled drugs.”

Dr. Velásquez is something of an outlier. He believes the abuse potential with psychedelics is poorly understood and that some patients may develop tolerance, which is a potential gateway to dependence.

“Such is the case with LSD,” he said, “where this substance also favors tolerance to other psychedelic drugs such as psilocybin.”

Dosing also seems to play a key role in mitigating potential abuse, said Luca Pani, MD, professor of pharmacology and psychiatry at the University of Modena, Italy. Dr. Pani explained that with low doses and microdoses of psychedelics, the potential for abuse is eliminated.

Dr. Nutt, Dr. Pani, and Dr. Ferreri also noted the importance of medical supervision. For instance, said Dr. Ferreri, when administering ketamine, his team closely monitors both mental and physical parameters – heart rate and blood pressure, in particular – because the drug can have hypertensive effects.

Dr. Schenberg noted that ibogaine, a naturally occurring psychedelic frequently used by traditional communities in Africa in rituals and for healing purposes, could cause potentially fatal arrhythmias, so it’s critical that the treatment is administered in a hospital setting that has a cardiac unit.

Dr. Pani said there is a need for more research, especially regarding the molecular mechanisms behind the behavioral effects of low-dose psychedelic therapy and the potential risks of multiple treatments with the drugs.

“Although extensive toxicology has been conducted on a single active dose of psilocybin, which has been proven to be safe, further research is required to understand better the possible health risks, especially in relation to cardiac and lung tissue,” he said.
 

Psychologically challenging

The experts note that given the relative lack of experience with psychedelic therapy, preparing patients for potential adverse effects is paramount. This is particularly relevant in the research setting and highlights the need for adequate patient screening and aftercare.

Dr. Gründer and Dr. Dolengevich-Segal emphasized the importance of having qualified personnel available in the event that patients experience adverse psychological events during treatment.

For Dr. Gründer, the potential for psilocybin to cause patients to lose control, experience psychotic symptoms, or become paranoid warrants considerable preparation by treating physicians.

Patients occasionally experience fear and anxiety during treatment, though it’s usually short-lived, said Dr. Griffiths. Nevertheless, these experiences may open the door to greater insight. “A number of people report that these psychologically challenging states are a valuable part of the overall experience,” he said.

The situation is similar in Spain, where Dr. Dolengevich-Segal noted that typical treatment regimens have a strong focus on the patient’s experience as a therapeutic tool. As in the United Kingdom and the United States, her team guides patients to what they call a “peak experience,” which allows them to gain a better understanding of the trauma underlying their mental health problems.

Dr. Nutt said that in the United Kingdom, they haven’t seen adverse reactions in patients receiving psychedelic therapy, although sedatives such as benzodiazepines could be used to manage them. He added that at his center, two therapists are present at every treatment session, and all personnel are “trained medics or psychologists.”
 

Patient education

Preparing and educating patients about the therapy are critical, said Dr. Gründer, especially given the intense response psychedelic treatment often invokes.

Echoing Dr. Gründer, Dr. Tófoli said explaining the nature of psychedelic treatment to potential patients helps ease anxiety.

Dr. Griffiths noted that in the United States, study participants are not only educated about the potential effects of psychedelic agents but also undergo several hours of psychological preparation in advance of their first treatment session and are provided with psychological support after treatment.

There is also a strong emphasis on patient preparation and education in the United Kingdom, where patients meet with therapists before and after treatment. During these posttreatment debriefings, clinicians use the patients’ experience with psychedelics to help them gain insight into the underlying cause of their depression.

Dr. Schenberg noted that at his institution in São Paulo, there are online courses to teach clinicians about psychedelic therapy for psychiatric disorders. Next year, he added, a new training program in MDMA-assisted psychotherapy will begin.
 

Working out treatment protocols

Treatment protocols for psychedelics vary by agent and indication from country to country. For instance, Dr. Pani noted that current psychedelic research in Italy predominantly focuses more on microdosing, which involves administering 1% of the pharmacologically active dose to a maximum of 100 mcg, in contrast to low dosing or full dosing.

Therapeutic regimens in Brazil, said Dr. Schenberg, also differ by agent but share common elements. For instance, psychedelics are always administered in a research setting, and sessions include concomitant psychotherapy.

In Germany, investigators are working to determine optimal treatment regimen for psilocybin for resistant depression in a randomized three-arm study planned for 2021.

For Mexico’s Dr. Velásquez, treatment regimens are complex and varied. Either way, he said, patients always require long-term follow-up.

With ketamine therapy, Dr. Ferreri said his team administers the drug in 45- to 60-minute intravenous infusion sessions in a hospital room without light or sound stimulation. Regardless of the drug’s immediate effect, he said, the protocol is repeated within a 6-month period.

The question of the duration of treatment effect is important. Dr. Griffiths said research suggests that the positive effects of psilocybin are long lasting and that most individuals report positive changes in mood, attitude, and behavior that endure for months or even years after the session.

“Our research has shown that the benefits of these experiences can last as long as 14 months, often longer, and that many participants characterize their psilocybin experience as among the most profound and personally meaningful experiences of their lives,” said Dr. Griffiths.

Dr. Nutt agreed, noting that a single intense “trip” can improve mood for weeks, months, or even years. Nevertheless, he said, in his experience, approximately three-quarters of patients treated with psychedelics for major depression relapse within 3-9 months.

“Most get better,” he said, “but the majority of depression comes back over a period of months.”

Given the current illegal status of the drugs, he said it’s nearly impossible to provide patients with regular, subsequent treatment with psychedelics over time.

“My suspicion is that you might well have to dose four or five times over a couple of years to get people to escape from very severe depression,” said Dr. Nutt. “The longer they’ve been depressed, the harder it is for them to make a full recovery, because it’s more entrenched in the brain.”

All experts agree that exciting times are ahead for psychedelics as therapeutics for a wide range of psychiatric disorders.

“We can look forward to continued growth and expansion of this research,” said Dr. Griffiths, “including the refinement of protocols for a variety of therapeutic indications and to the development of a variety of new classic psychedelic compounds.”

Psychedelics induce altered states of perception. They bind to the 5-hydroxytryptamine 2A (5-HT2A) receptor and include psilocybin, which is derived from “magic mushrooms”; N,N-dimethyltryptamine (DMT), a component of ayahuasca and mescaline (peyote cactus); and the synthesized compound D-lysergic acid diethylamide (LSD). Other agents, such as ketamine and 3,4-methylenedioxymethamphetamine (MDMA), also known as ecstasy, are sometimes considered psychedelics as well.

Before they were classified as schedule I agents, psychedelics had been shown to be particularly beneficial for patients with treatment-resistant conditions, including depression and posttraumatic stress disorder (PTSD), especially when administered in a supportive, therapeutic setting.

Now, after a hiatus of almost 50 years, there is renewed global interest in the scientific investigation of psychedelics. The attention was spurred in part by several exploratory studies of DMT in humans conducted in the 1990s by Rick Strassman, MD, and colleagues at the University of New Mexico, Albuquerque.

Around the same time, Franz X. Vollenweider, MD, and colleagues at the University of Zürich began researching psilocybin and its effects on human behavior. However, it was a 2006 study of psilocybin by a team of researchers at Johns Hopkins University, Baltimore, that is widely cited as a catalyst for the current renaissance in psychedelic research.

To provide a broad-based, international perspective on these agents, including their current legal status and indications, treatment regimens, safety, efficacy, and future considerations, this news organization interviewed nine expert researchers from around the globe.
 

Global legal status

In most, if not all, countries, it is still illegal to prescribe psychedelics in other than a research setting.

In the United States, classic psychedelics remain schedule I substances and therefore are unavailable for clinical use. They can be used in research, but only with approval from the Food and Drug Administration under licensure from the Drug Enforcement Administration.

France lists all synthetic hallucinogens and hallucinogenic mushrooms as narcotic. As a result, possession, use, transportation, and collection are subject to criminal sanctions.

In France, NMDA antagonists such as ketamine and nitrous oxide are regarded as psychedelic molecules and can be used off label for various conditions or as part of research protocols authorized by the French public health code.

Although psychedelics are illegal under Mexican law, they are commonly used in indigenous communities as part of traditional rituals.

“The line between traditional consumption and psychedelic tourism is very thin,” José J. Mendoza Velásquez, MD, professor in the department of mental health, National Autonomous University of Mexico, Mexico City, said in an interview.

Psychedelics also are illegal in the United Kingdom, although government agencies have recently allowed research groups to investigate them. Psychedelics cannot be prescribed in Germany, Spain, or Italy. However, investigators in these countries can request permission from regulatory agencies to conduct research.

Brazil allows psychedelic substances to be researched, particularly ayahuasca, which has long traditional and religious roots in the country.

However, as in other countries, none of the classic psychedelics is regulated for therapeutic use in Brazil. It is widely expected that the Brazilian government will approve MDMA sometime in 2024 for use in the treatment of PTSD.
 

Potential indications

Psychedelics are currently under investigation as potential treatments for major depression, treatment-resistant depression, PTSD, pain management, and anorexia, among other conditions.

In France, Florian Ferreri, MD, PhD, at Hospital Saint-Antoine, Paris, is researching ketamine for treatment of patients with suicidal crisis/ideation and treatment-resistant depression.

In the United Kingdom, David Nutt, FMedSci, Edmond J. Safra Professor of Neuropsychopharmacology at Imperial College London, and his team have conducted studies of the use of psychedelics in conjunction with psychological support for patients with treatment-resistant depression, and they are currently exploring their use in the treatment of anorexia and various pain syndromes.

In Germany, Gerhard Gründer, MD, professor of psychiatry at the Central Institute of Mental Health, in Mannheim, noted that a study of psilocybin for treatment-resistant depression will launch sometime in 2021. In Italy, current research is focusing on MDMA and ketamine in the laboratory environment and in animal models for treating depression and drug abuse.

Researcher Helen Dolengevich-Segal, MD, a psychiatrist at Hospital Universitario del Henares, Madrid, noted that although research on esketamine for the treatment of severe depressive disorder with suicidal thoughts is underway, there is very limited published research from that country into the use of classic psychedelics for various psychiatric disorders, given their current illegal status.

Echoing Dr. Gründer, Dr. Tófoli said explaining the nature of psychedelic treatment to potential patients helps ease anxiety.

Dr. Griffiths noted that in the United States, study participants are not only educated about the potential effects of psychedelic agents but also undergo several hours of psychological preparation in advance of their first treatment session and are provided with psychological support after treatment.

There is also a strong emphasis on patient preparation and education in the United Kingdom, where patients meet with therapists before and after treatment. During these posttreatment debriefings, clinicians use the patients’ experience with psychedelics to help them gain insight into the underlying cause of their depression.

Dr. Schenberg noted that at his institution in São Paulo, there are online courses to teach clinicians about psychedelic therapy for psychiatric disorders. Next year, he added, a new training program in MDMA-assisted psychotherapy will begin.
 

Working out treatment protocols

Treatment protocols for psychedelics vary by agent and indication from country to country. For instance, Dr. Pani noted that current psychedelic research in Italy predominantly focuses more on microdosing, which involves administering 1% of the pharmacologically active dose to a maximum of 100 mcg, in contrast to low dosing or full dosing.

Therapeutic regimens in Brazil, said Dr. Schenberg, also differ by agent but share common elements. For instance, psychedelics are always administered in a research setting, and sessions include concomitant psychotherapy.

In Germany, investigators are working to determine optimal treatment regimen for psilocybin for resistant depression in a randomized three-arm study planned for 2021.

For Mexico’s Dr. Velásquez, treatment regimens are complex and varied. Either way, he said, patients always require long-term follow-up.

With ketamine therapy, Dr. Ferreri said his team administers the drug in 45- to 60-minute intravenous infusion sessions in a hospital room without light or sound stimulation. Regardless of the drug’s immediate effect, he said, the protocol is repeated within a 6-month period.

The question of the duration of treatment effect is important. Dr. Griffiths said research suggests that the positive effects of psilocybin are long lasting and that most individuals report positive changes in mood, attitude, and behavior that endure for months or even years after the session.

“Our research has shown that the benefits of these experiences can last as long as 14 months, often longer, and that many participants characterize their psilocybin experience as among the most profound and personally meaningful experiences of their lives,” said Dr. Griffiths.

Dr. Nutt agreed, noting that a single intense “trip” can improve mood for weeks, months, or even years. Nevertheless, he said, in his experience, approximately three-quarters of patients treated with psychedelics for major depression relapse within 3-9 months.

“Most get better,” he said, “but the majority of depression comes back over a period of months.”

Given the current illegal status of the drugs, he said it’s nearly impossible to provide patients with regular, subsequent treatment with psychedelics over time.

“My suspicion is that you might well have to dose four or five times over a couple of years to get people to escape from very severe depression,” said Dr. Nutt. “The longer they’ve been depressed, the harder it is for them to make a full recovery, because it’s more entrenched in the brain.”

All experts agree that exciting times are ahead for psychedelics as therapeutics for a wide range of psychiatric disorders.

“We can look forward to continued growth and expansion of this research,” said Dr. Griffiths, “including the refinement of protocols for a variety of therapeutic indications and to the development of a variety of new classic psychedelic compounds.”

Seasonal time change is now up for consideration in the U.S. Congress, prompting sleep medicine specialists to weigh in on the health impact of a major policy change.

As lawmakers in Washington propose an end to seasonal time changes by permanently establishing daylight saving time (DST), the American Academy of Sleep Medicine (AASM) is pushing for a Congressional hearing so scientists can present evidence in favor of converse legislation – to make standard time the new norm.

According to the AASM, seasonal time changes in either direction have been associated with a range of detrimental health effects; however, the switch from standard time to DST incurs more risk.

“Current evidence best supports the adoption of year-round standard time, which aligns best with human circadian biology and provides distinct benefits for public health and safety,” the AASM noted in a 2020 position statement on DST.

The statement cites a number of studies that have reported associations between the switch to DST and acute, negative health outcomes, including higher rates of hospital admission, cardiovascular morbidity, atrial fibrillation, and stroke. The time shift has been associated with a spectrum of cellular, metabolic, and circadian derangements, from increased production of inflammatory markers, to higher blood pressure, and loss of sleep. These biological effects may have far-reaching consequences, including increased rates of fatal motor accidents in the days following the time change, and even increased volatility in the stock market, which may stem from cognitive deficits.

U.S. Senator Marco Rubio (R-Fla.) and others in the U.S. Congress have reintroduced the 2019 Sunshine Protection Act, legislation that would make DST permanent across the country. According to a statement on Sen. Rubio’s website, “The bill reflects the Florida legislature’s 2018 enactment of year-round DST; however, for Florida’s change to apply, a change in the federal statute is required. Fifteen other states – Arkansas, Alabama, California, Delaware, Georgia, Idaho, Louisiana, Maine, Ohio, Oregon, South Carolina, Tennessee, Utah, Washington, and Wyoming – have passed similar laws, resolutions, or voter initiatives, and dozens more are looking. The legislation, if enacted, would apply to those states [that] currently participate in DST, which most states observe for eight months out of the year.”
 

A stitch in time

“The sudden change in clock time disrupts sleep/wake patterns, decreasing total sleep time and sleep quality, leading to decrements in daytime cognition,” said Kannan Ramar, MBBS, MD, president of the AASM and a sleep medicine specialist at Mayo Clinic, Rochester, Minn. 

Emphasizing this point, Dr. Ramar noted a recent study that reported an 18% increase in “patient safety-related incidents associated with human error” among health care workers within a week of the spring time change.

“Irregular bedtimes and wake times disrupt the timing of our circadian rhythms, which can lead to symptoms of insomnia or long-term, excessive daytime sleepiness. Lack of sleep can lead to numerous adverse effects on our minds, including decreased cognitive function, trouble concentrating, and general moodiness,” Dr. Ramar said.

He noted that these impacts may be more significant among certain individuals.

“The daylight saving time changes can be especially problematic for any populations that already experience chronic insufficient sleep or other sleep difficulties,” Dr. Ramar said. “Populations at greatest risk include teenagers, who tend to experience chronic sleep restriction during the school week, and night shift workers, who often struggle to sleep well during daytime hours.”

While fewer studies have evaluated the long-term effects of seasonal time changes, the AASM position statement cited evidence that “the body clock does not adjust to daylight saving time after several months,” possibly because “daylight saving time is less well-aligned with intrinsic human circadian physiology, and it disrupts the natural seasonal adjustment of the human clock due to the effect of late-evening light on the circadian rhythm.”

According to the AASM, permanent DST, as proposed by Sen. Rubio and colleagues, could “result in permanent phase delay, a condition that can also lead to a perpetual discrepancy between the innate biological clock and the extrinsic environmental clock, as well as chronic sleep loss due to early morning social demands that truncate the opportunity to sleep.” This mismatch between sleep/wake cycles and social demands, known as “social jet lag,” has been associated with chronic health risks, including metabolic syndrome, obesity, depression, and cardiovascular disease.
 

Cardiac impacts of seasonal time change

Muhammad Adeel Rishi, MD, a sleep specialist at Mayo Clinic, Eau Claire, Wis., and lead author of the AASM position statement, highlighted cardiovascular risks in a written statement for this article, noting increased rates of heart attack following the spring time change, and a higher risk of atrial fibrillation.

“Mayo Clinic has not taken a position on this issue,” Dr. Rishi noted. Still, he advocated for permanent standard time as the author of the AASM position statement and vice chair of the AASM public safety committee.

Jay Chudow, MD, and Andrew K. Krumerman, MD, of Montefiore Medical Center, New York, lead author and principal author, respectively, of a recent study that reported increased rates of atrial fibrillation admissions after DST transitions, had the same stance.

Pros and cons

Not all sleep experts are convinced. Mary Jo Farmer, MD, PhD, FCCP, a sleep specialist and director of pulmonary hypertension services at Baystate Medical Center, and assistant professor of medicine at the University of Massachusetts, Springfield, considers perspectives from both sides of the issue.

“Daylight saving time promotes active lifestyles as people engage in more outdoor activities after work and school, [and] daylight saving time produces economic and safety benefits to society as retail revenues are higher and crimes are lower,” Dr. Farmer said. “Alternatively, moving the clocks forward is a cost burden to the U.S. economy when health issues, decreased productivity, and workplace injuries are considered.”

If one time system is permanently established, Dr. Farmer anticipates divided opinions from patients with sleep issues, regardless of which system is chosen.

“I can tell you, I have a cohort of sleep patients who prefer more evening light and look forward to the spring time change to daylight saving time,” she said. “However, they would not want the sun coming up at 9:00 a.m. in the winter months if we stayed on daylight saving time year-round. Similarly, patients would not want the sun coming up at 4:00 a.m. on the longest day of the year if we stayed on standard time all year round.”

Dr. Farmer called for more research before a decision is made.

“I suggest we need more information about the dangers of staying on daylight saving or standard time year-round because perhaps the current strategy of keeping morning light consistent is not so bad,” she said.
 

Time for a Congressional hearing?

According to Dr. Ramar, the time is now for a Congressional hearing, as lawmakers and the public need to be adequately informed when considering new legislation.

“There are public misconceptions about daylight saving time and standard time,” Dr. Ramar said. “People often like the idea of daylight saving time because they think it provides more light, and they dislike the concept of standard time because they think it provides more darkness. The reality is that neither time system provides more light or darkness than the other; it is only the timing that changes.”

Until new legislation is introduced, Dr. Ramar offered some practical advice for navigating seasonal time shifts.

“Beginning 2-3 days before the time change, it can be helpful to gradually adjust sleep and wake times, as well as other daily routines such as meal times,” he said. “After the time change, going outside for some morning light can help adjust the timing of your internal body clock.”

The investigators reported no conflicts of interest.

More sleep at night, fewer or no sleep problems, and low levels of professional burnout were associated with a lower risk of developing COVID-19 among health care workers considered to be at high risk for exposure to patients with COVID-19, new evidence reveals.

PRImageFactory/iStock/Getty Images

For each additional hour of sleep at night, for example, risk for COVID-19 dropped by 12% in a study of 2844 frontline health care workers.

Furthermore, those who reported experiencing work-related burnout every day were 2.6 times more likely to report having COVID-19, to report having COVID-19 for a longer time, and to experience COVID-19 of more severity.

“This study underscores the importance of non–hygiene-related risk factors for COVID-19 and supports a holistic approach to health – including optimal sleep and job stress reduction to protect our health care workers from this and future pandemics,” senior author Sara B. Seidelmann, MD, said in an interview.

“Our findings add to the literature that sleep duration at night, sleep problems, and burnout may be risk factors for viral illnesses like COVID-19,” wrote Dr. Seidelmann and colleagues.

This is the first study to link COVID-19 risk to sleep habits – including number of hours of sleep at night, daytime napping hours, and severe sleep problems – among health care workers across multiple countries.

The study was published online March 22 in BMJ Nutrition, Prevention, and Health.

The researchers surveyed health care professionals in specialties considered to place personnel at high risk for exposure to SARS-CoV-2: critical care, emergency care, and internal medicine.

The association between sleep and burnout risk factors and COVID-19 did not vary significantly by specialty. “We didn’t detect any significant interactions between age, sex, specialty, or country,” said Dr. Seidelmann, assistant professor of clinical medicine at Columbia University College of Physicians and Surgeons, New York, and an internist at Stamford (Conn.) Hospital.

In addition to the 12% lower risk associated with each additional hour of sleep at night, each 1 additional hour of daytime napping was linked with a 6% increased risk for COVID-19 in an adjusted analysis (odds ratio [OR], 1.06; 95% confidence interval [CI], 1.01-1.12).

Daytime napping slightly increased risk for COVID-19 in five of the six countries included in the study: France, Germany, Italy, the United Kingdom, and the United States. In contrast, in Spain, napping had a nonsignificant protective effect.

The survey asked health care workers to recall nighttime sleep duration, sleep disorders, and burnout in the year prior to onset of the COVID-19 pandemic.
 

‘Significant, close contact’ with COVID-19?

Lead author Hyunju Kim, NP, Dr. Seidelmann, and colleagues conducted the population-based, case-control study from July 17 to Sept. 25, 2020. They identified health care workers from the SurveyHealthcareGlobus (SHG) network.

Of the respondents, 72% were men. The mean age of the participants was 48 years, and the study population was 77% White, 12% Asian, 6% mixed background, 2% Black, and 1% other. (The remainder preferred not to say).

The 568 health care workers considered to have COVID-19 were classified on the basis of self-reported symptoms. Control participants had no symptoms associated with COVID-19.

All 2,844 participants answered yes to a question about having “significant close contact” with COVID-19 patients in their workplace.

Compared to reporting no sleep problems, having three such problems – difficulty sleeping at night, poor sleep continuity, and frequent use of sleeping pills – was associated with 88% greater odds of COVID-19 (OR, 1.88; 95% CI, 1.17–3.01).

Having one sleep problem was not associated with COVID-19.
 

More burnout, greater risk

The health care workers reported the severity of any work-related burnout. “There was a significant dose-response relationship between frequency of burnout and COVID-19,” the researchers noted.

Those who reported having burnout rarely or weekly had a 1.3-1.4 greater chance of reporting COVID-19 compared to those who reported having no burnout, for example.

In addition, reporting a high level of burnout was linked to about three times the risk for having COVID-19 of longer duration and of greater severity.

What drives the association between sleep problems, burnout, and higher risk for COVID-19 and severe COVID-19 remains unknown.

“The mechanism underlying these associations isn’t clear, but suboptimal sleep, sleep disorders, and stress may result in immune system dysregulation, increased inflammation, and alterations in hormones such as cortisol and melatonin that may increase vulnerability to viral infections,” Dr. Seidelmann said.
 

Strengths and limitations

Using a large network of health care workers in the early phase of the pandemic is a strength of the study. How generalizable the findings are outside the SHG database of 1.5 million health care workers remains unknown.

Another limitation was reliance on self-reporting of COVID-19 patient exposure, outcomes, and covariates, which could have introduced bias.

“However,” the researchers noted, “health care workers are likely a reliable source of information.”
 

Insomnia a common challenge

A 2020 meta-analysis examined the effect of insomnia and psychological factors on COVID-19 risk among health care workers. Lead author Kavita Batra, PhD, of the University of Nevada, Las Vegas (UNLV), and colleagues found that the pooled prevalence of insomnia was almost 28%.

“The recent six-country study by Kim and colleagues also underscores this relationship between lack of sleep and having higher odds of COVID-19 infection,” Manoj Sharma, MBBS, PhD, professor of social and behavioral health in the UNLV department of environmental and occupational health, and one of the study authors, said in an interview.

More research is warranted to learn the direction of the association, he said. Does reduced sleep lower immunity and make a health care worker more susceptible to SARS-CoV-2 infection, or does the anxiety associated with COVID-19 contribute to insomnia?

“Practicing sleep hygiene is a must not only for health workers but also for everyone,” Dr. Sharma added. Recommendations include having fixed hours of going to bed, fixed hours of waking up, not overdoing naps, having at least 30 minutes of winding down before sleeping, having a dark bedroom devoid of all electronics and other disturbances, avoiding smoking, alcohol, and stimulants (such as caffeine) before sleeping, and practicing relaxation right before sleeping, he said.

“It is hard for some health care workers, especially those who work night shifts, but it must be a priority to follow as many sleep hygiene measures as possible,” Dr. Sharma said. “After all, if you do not take care of yourself how can you take care of others?”

Dr. Seidelmann, Dr. Batra, and Dr. Sharma have disclosed no relevant financial relationships.

Lead author Hyunju Kim, NP, Dr. Seidelmann, and colleagues conducted the population-based, case-control study from July 17 to Sept. 25, 2020. They identified health care workers from the SurveyHealthcareGlobus (SHG) network.

Of the respondents, 72% were men. The mean age of the participants was 48 years, and the study population was 77% White, 12% Asian, 6% mixed background, 2% Black, and 1% other. (The remainder preferred not to say).

The 568 health care workers considered to have COVID-19 were classified on the basis of self-reported symptoms. Control participants had no symptoms associated with COVID-19.

All 2,844 participants answered yes to a question about having “significant close contact” with COVID-19 patients in their workplace.

Compared to reporting no sleep problems, having three such problems – difficulty sleeping at night, poor sleep continuity, and frequent use of sleeping pills – was associated with 88% greater odds of COVID-19 (OR, 1.88; 95% CI, 1.17–3.01).

Having one sleep problem was not associated with COVID-19.
 

More burnout, greater risk

The health care workers reported the severity of any work-related burnout. “There was a significant dose-response relationship between frequency of burnout and COVID-19,” the researchers noted.

Those who reported having burnout rarely or weekly had a 1.3-1.4 greater chance of reporting COVID-19 compared to those who reported having no burnout, for example.

In addition, reporting a high level of burnout was linked to about three times the risk for having COVID-19 of longer duration and of greater severity.

What drives the association between sleep problems, burnout, and higher risk for COVID-19 and severe COVID-19 remains unknown.

“The mechanism underlying these associations isn’t clear, but suboptimal sleep, sleep disorders, and stress may result in immune system dysregulation, increased inflammation, and alterations in hormones such as cortisol and melatonin that may increase vulnerability to viral infections,” Dr. Seidelmann said.
 

Strengths and limitations

Using a large network of health care workers in the early phase of the pandemic is a strength of the study. How generalizable the findings are outside the SHG database of 1.5 million health care workers remains unknown.

Another limitation was reliance on self-reporting of COVID-19 patient exposure, outcomes, and covariates, which could have introduced bias.

“However,” the researchers noted, “health care workers are likely a reliable source of information.”
 

Insomnia a common challenge

A 2020 meta-analysis examined the effect of insomnia and psychological factors on COVID-19 risk among health care workers. Lead author Kavita Batra, PhD, of the University of Nevada, Las Vegas (UNLV), and colleagues found that the pooled prevalence of insomnia was almost 28%.

“The recent six-country study by Kim and colleagues also underscores this relationship between lack of sleep and having higher odds of COVID-19 infection,” Manoj Sharma, MBBS, PhD, professor of social and behavioral health in the UNLV department of environmental and occupational health, and one of the study authors, said in an interview.

More research is warranted to learn the direction of the association, he said. Does reduced sleep lower immunity and make a health care worker more susceptible to SARS-CoV-2 infection, or does the anxiety associated with COVID-19 contribute to insomnia?

“Practicing sleep hygiene is a must not only for health workers but also for everyone,” Dr. Sharma added. Recommendations include having fixed hours of going to bed, fixed hours of waking up, not overdoing naps, having at least 30 minutes of winding down before sleeping, having a dark bedroom devoid of all electronics and other disturbances, avoiding smoking, alcohol, and stimulants (such as caffeine) before sleeping, and practicing relaxation right before sleeping, he said.

“It is hard for some health care workers, especially those who work night shifts, but it must be a priority to follow as many sleep hygiene measures as possible,” Dr. Sharma said. “After all, if you do not take care of yourself how can you take care of others?”

Dr. Seidelmann, Dr. Batra, and Dr. Sharma have disclosed no relevant financial relationships.

More sleep at night, fewer or no sleep problems, and low levels of professional burnout were associated with a lower risk of developing COVID-19 among health care workers considered to be at high risk for exposure to patients with COVID-19, new evidence reveals.

For each additional hour of sleep at night, for example, risk for COVID-19 dropped by 12% in a study of 2844 frontline health care workers.

Furthermore, those who reported experiencing work-related burnout every day were 2.6 times more likely to report having COVID-19, to report having COVID-19 for a longer time, and to experience COVID-19 of more severity.

“This study underscores the importance of non–hygiene-related risk factors for COVID-19 and supports a holistic approach to health – including optimal sleep and job stress reduction to protect our health care workers from this and future pandemics,” senior author Sara B. Seidelmann, MD, said in an interview.

“Our findings add to the literature that sleep duration at night, sleep problems, and burnout may be risk factors for viral illnesses like COVID-19,” wrote Dr. Seidelmann and colleagues.

This is the first study to link COVID-19 risk to sleep habits – including number of hours of sleep at night, daytime napping hours, and severe sleep problems – among health care workers across multiple countries.

The study was published online March 22 in BMJ Nutrition, Prevention, and Health.

The researchers surveyed health care professionals in specialties considered to place personnel at high risk for exposure to SARS-CoV-2: critical care, emergency care, and internal medicine.

The association between sleep and burnout risk factors and COVID-19 did not vary significantly by specialty. “We didn’t detect any significant interactions between age, sex, specialty, or country,” said Dr. Seidelmann, assistant professor of clinical medicine at Columbia University College of Physicians and Surgeons, New York, and an internist at Stamford (Conn.) Hospital.

In addition to the 12% lower risk associated with each additional hour of sleep at night, each 1 additional hour of daytime napping was linked with a 6% increased risk for COVID-19 in an adjusted analysis (odds ratio [OR], 1.06; 95% confidence interval [CI], 1.01-1.12).

Daytime napping slightly increased risk for COVID-19 in five of the six countries included in the study: France, Germany, Italy, the United Kingdom, and the United States. In contrast, in Spain, napping had a nonsignificant protective effect.

The survey asked health care workers to recall nighttime sleep duration, sleep disorders, and burnout in the year prior to onset of the COVID-19 pandemic.
