The Centers for Disease Control and Prevention is considering what to tell the public about second booster shots with mRNA vaccinations for COVID-19.

The U.S. Food and Drug Administration in March authorized a second booster dose of either the Pfizer-BioNTech or the Moderna COVID-19 vaccines for people aged 50 and older and certain immunocompromised adults, even though many top infectious disease experts questioned the need before the agency’s decision.

In a meeting April 20, the CDC asked its Advisory Committee on Immunization Practices to discuss second booster shots, but did not ask the group of experts to vote on formal recommendations.

Instead, the experts talked about the potential timing of additional COVID-19 vaccines for those who already have had three shots, and challenges for vaccination efforts that likely will arise as the pandemic persists.

ACIP member Beth Bell, MD, MPH, of the University of Washington, Seattle, said she’s concerned about the potential for “booster fatigue.”

“A vaccination program that’s going to require boosting large proportions of the population every 4-6 months is really not sustainable and probably not something that most people want to participate in,” she said.

The benefit of additional COVID-19 shots for now appears to be smaller than what people get from the initial doses, Dr. Bell said.

Earlier in the meeting, CDC staff presented estimates about how well the COVID-19 vaccines work to prevent one case of hospitalization from the disease over 4 months among people aged 50 and older.

The major gain in preventing hospitalizations occurs with the first vaccination series and then wanes, the CDC said.

It appears that one hospitalization is prevented for every 135 people who get the first round of COVID-19 vaccinations. But it takes 674 people getting a first booster dose to prevent one hospitalization. A second booster prevents one hospitalization for every 1,205 people vaccinated.

Dr. Bell said she’s concerned about considering additional doses for “smaller and smaller return and creating an impression that we don’t have a very effective vaccination program,” even though the CDC’s data show a clear benefit.
 

Reasons to get a second booster

Elisha Hall, PhD, RD, of the CDC presented slides with some factors to help determine the urgency for a person to get a second booster:

• Having certain underlying medical conditions that increase the risk of severe COVID-19 illness.
• Being moderately or severely immunocompromised.
• Living with someone who is immunocompromised, at increased risk for severe disease, or who cannot be vaccinated because of age or contraindication.
• Being at increased risk of exposure to SARS-CoV-2, the virus that causes COVID-19, such as through occupational, institutional, or other activities (e.g., travel or large gatherings).
• Living or working in an area where there is a medium or high level of COVID-19 in the community.

In contrast, people might want to wait if they had been infected with SARS-CoV-2 within the past 3 months, Dr. Hall said in her presentation. Another reason for delay might be a concern that a booster dose may be more important later in the year.

The experts also addressed public confusion over boosters. For the Pfizer and Moderna mRNA vaccines, a second booster is a fourth dose, but for those who received the one-shot J&J vaccine, the second booster is a third dose.

Going forward, it may be easier to refer to subsequent doses as “annual boosters,” the CDC’s Sara Oliver, MD, MSPH, told the panel. It will be important to keep language about subsequent vaccinations clear and easy for the public to follow, she said.

Dr. Oliver also said there’s already been a drop-off in the acceptance of second rounds of COVID-19 vaccinations. CDC data show that 77% of people in the United States have had at least one dose of a COVID-19 vaccine, but only 66% of the population is fully vaccinated, and only 45% have had a first booster dose.

In her presentation, Dr. Oliver said the top priority in COVID-19 vaccination efforts remains initial vaccinations for people who haven’t gotten them.
 

Kids younger than 5

During the public comment session of the CDC meeting, several people called on the FDA to move quickly to expand authorization of COVID-19 vaccines to children aged 5 years and younger.

“We know that many parents and caregivers and health care providers are anxious to have COVID vaccines available” for young children, said Doran Fink, MD, PhD, a deputy director of the FDA’s vaccines division.

He said the agency is working to be ready to authorize the shots for young children while it awaits research results from the manufacturers.

For 4 and a half years, I have followed the RaDonda Vaught medication error that led to the unfortunate death of a human being. I am not alone. Nurses across the country have followed the case with anxiety and fear, knowing a guilty verdict might have the potential to challenge basic tenets of care.

According to Kaiser Health News, nurses are “raging and quitting” following the announcement of a guilty verdict for two felonies: criminally negligent homicide and gross neglect of an impaired adult.

Thousands of nurses have claimed they could arrive in Nashville, Tenn., on May 13, the day Ms. Vaught is to be sentenced, to protest the conviction. Others have stated they believe justice is being conducted, as their sympathies lie with the victim, Charlene Murphey, who died 12 hours after being unable to draw breath, paralyzed from the inadvertent dose of vecuronium given intravenously by her nurse.

How should we feel as clinicians? What does this guilty verdict mean for nurses across the country as Ms. Vaught waits to receive a sentence that could imprison her for up to 8 years, according to sentencing guidelines?

My belief is that it is understandable to feel passionately about this case, including what it could mean to an era of “just culture” that nursing organizations have promoted. The concept of just culture looks at medication/nursing errors as opportunities for growth to avoid future errors, not as scenarios for punitive action. With the guilty verdict in Ms. Vaught’s case, nurses (and facilities) fear that nurses will avoid coming forward after mistakes, leading to cover-ups and a culture perspective.

Will nurses be hesitant to report errors (especially significant errors) that lead to patient harm? Will we fear retribution and reprisal for being truthful?

I believe that Ms. Vaught’s criminal case has changed little in the political landscape of caregiving. Before you let loose with a loud expletive (or two), hear me out.

When a patient dies from unintentional harm, someone must be held accountable. Society needs a scapegoat, and unfortunately, excrement slides downhill to the lowest common denominator, which may be the nurse. Initially, Ms. Vaught was contacted by her state licensing board (Tennessee) and informed there would be no professional repercussions for her mistake. That decision did not hold. She was later indicted criminally for the death of her patient. She also had her nursing license revoked.

Why? The hospital where she worked was threatened with Medicare reprisal if systemic issues were not addressed following the incident; for example, a bar-coding device was not available for Ms. Vaught to use prior to administering the vecuronium, and paralytic agents were stored unsafely in a Pyxis MedStation, readily available for any nurse to obtain via override.

In fact, the number of overrides performed by all nurses caring for Ms. Murphey in the days leading to her death was alarming, leading reviewers to assume that time to acquire medication for inpatients was a problem.

Ms. Vaught herself, stating the obvious on talk shows, said she should not have performed an override, that the situation was “not an emergency” and she should have taken time to check that Versed (midazolam) was available by the generic name and not the “VE” she entered as a search mechanism into the machine. She also stated she was “distracted” by a trainee assigned to her at the time.

We have all been there, feeling rushed to perform a task under stressful situations, skipping safety guidelines to sedate a patient while radiology is waiting. Someone is always on our a**, waiting to get to the next task, the next patient, the next admission, the next pseudo-emergency called nursing workload.

It never ends.

Which is why I wish to emphasize what the Ms. Vaught guilty verdict really means for nurses.

It means we must never forget that our actions have the potential to harm, even kill, our patients.

We must never forget that repercussions and reprisal may occur, whether personal guilt that may prove more damaging than the prison sentence Ms. Vaught might receive, or problems that could result if nurses attempt to hide or subvert medication issues.

In Ms. Vaught’s case, she did not document the medication that had been given to Ms. Murphey, facts the prosecution seized on to proclaim her guilt. Why? We can only guess at this point. But her claims of truthfulness need to be balanced by what occurred, and the facts are that she did not document the error after administering vecuronium that night.

When reflecting on this verdict, we need to remember a patient died, and she did so horribly, being unable to draw breath. This should never happen during our watch, ever, and as clinicians, we need to be vigilant.

In summary, protest if you believe justice has been too harsh or unfair, and that nurses may be fearful as a result. But please spare a moment to realize that someone should protest for Ms. Murphey as well. We cannot bring her back, nor can we right the system issues that may have led to her death.

But we should protest for safer systems, for improved staffing, for a need to catch our collective breaths, and a day to work and nurture patients when someone is not constantly on our a**. Only then will nurses be protected from unjust reprisal, from needing to be the lowest common denominator of guilt.

About 30% of COVID-19 patients developed the condition known as long COVID, University of California, Los Angeles, researchers said in a study published in the Journal of General Internal Medicine.

The UCLA researchers studied 1,038 people enrolled in the UCLA COVID Ambulatory Program between April 2020 and February 2021 and found that 309 developed long COVID.

A long-COVID diagnosis came if a patient answering a questionnaire reported persistent symptoms 60-90 days after they were infected or hospitalized. The most persistent symptoms were fatigue (31%) and shortness of breath (15%) in hospitalized participants. Among outpatients, 16% reported losing sense of smell.

The study’s findings differ from earlier research. The University of California, Davis, for example, estimated that 10% of COVID-19 patients develop long-haul symptoms. A 2021 study from Penn State University found that more than half of worldwide COVID-19 patients would develop long COVID.

Part of the discrepancy can blamed on the fact there is no official, widely accepted definition of long COVID. The Centers for Disease Control and Prevention has said it means patients who experience “new, returning, or ongoing health problems 4 or more weeks after an initial infection” the coronavirus. The UCLA study, meanwhile, included patients still having symptoms 60-90 days after infection.

Still, the UCLA research team looked at demographics and clinical characteristics in an attempt to develop effective treatments.

People with a history of hospitalization, diabetes, and higher body mass index were most likely to develop long COVID, the researchers said. The kind of insurance the patients had also seemed to be a factor, though the researchers didn’t offer a reason why.

“Surprisingly, patients with commercial insurance had double the likelihood of developing [long COVID] compared to patients with Medicaid,” they wrote. “This association will be important to explore further to understand if insurance status in this group is representing unmeasured demographic factors or exposures.”

Older age and socioeconomic status were not associated with long COVID in the study – a surprise because those characteristics are often linked with severe illness and higher risk of death from COVID-19.

Weaknesses in the study included the subjective nature of how patients rated their symptoms and the limited number of symptoms evaluated.

“This study illustrates the need to follow diverse patient populations ... to understand the long COVID disease trajectory and evaluate how individual factors such as preexisting comorbidities, sociodemographic factors, vaccination status and virus variant type affect type and persistence of long COVID symptoms,” said Sun Yoo, MD, health sciences assistant clinical professor at UCLA.

The Centers for Disease Control and Prevention has said it means patients who experience “new, returning, or ongoing health problems 4 or more weeks after an initial infection” the coronavirus. The UCLA study, meanwhile, included patients still having symptoms 60-90 days after infection.

Still, the UCLA research team looked at demographics and clinical characteristics in an attempt to develop effective treatments.

People with a history of hospitalization, diabetes, and higher body mass index were most likely to develop long COVID, the researchers said. The kind of insurance the patients had also seemed to be a factor, though the researchers didn’t offer a reason why.

“Surprisingly, patients with commercial insurance had double the likelihood of developing [long COVID] compared to patients with Medicaid,” they wrote. “This association will be important to explore further to understand if insurance status in this group is representing unmeasured demographic factors or exposures.”

Older age and socioeconomic status were not associated with long COVID in the study – a surprise because those characteristics are often linked with severe illness and higher risk of death from COVID-19.

Weaknesses in the study included the subjective nature of how patients rated their symptoms and the limited number of symptoms evaluated.

“This study illustrates the need to follow diverse patient populations ... to understand the long COVID disease trajectory and evaluate how individual factors such as preexisting comorbidities, sociodemographic factors, vaccination status and virus variant type affect type and persistence of long COVID symptoms,” said Sun Yoo, MD, health sciences assistant clinical professor at UCLA.

The force is with Ukraine, always

Of all the things we could want from Star Wars, a lightsaber is at the top of the list. And someone is working on that. But second is probably the iconic X-wing. It was used to blow up the Death Star after all: Who wouldn’t want one?

A real-life star fighter may be outside our technological capabilities, but Dr. Akaki Lekiachvili of Atlanta has done the next best thing and constructed a two-thirds scale model to encourage kids to enter the sciences and, with the advent of the war in Ukraine, raise money for medical supplies to assist doctors in the embattled country. Perhaps unsurprisingly, Dr. Lekiachvili, originally from Georgia (the country, former Soviet republic, and previous target of Russian aggression in 2008), takes a dim view toward the invasion of Ukraine: “Russia is like the Evil Empire and Ukraine the Rebel Alliance.”

It’s been a long road finishing the X-Wing, as Dr. Lekiachvili started the project in 2016 and spent $60,000 on it, posting numerous updates on social media over that time, even attracting the attention of Luke Skywalker himself, actor Mark Hamill. Now that he’s done, he’s brought his model out to the public multiple times, delighting kids and adults alike. It can’t fly, but it has an engine and wheels so it can move, the wings can lock into attack position, the thrusters light up, and the voices of Obi-Wan Kenobi and R2-D2 guide children along as they sit in the cockpit.

Dr. Lekiachvili hopes to auction off his creation to a collector and donate the proceeds to Ukrainian charities, and we’re sure he’ll receive far more than the $60,000 he spent building his masterpiece. Now, if you’ll excuse us, we’re off to raid our bank accounts. We have a Death Star to destroy.
 

I’m a doctor, not a hologram

Telemedicine got a big boost during the early phase of the pandemic when hospitals and medical offices were off limits to anyone without COVID-19, but things have cooled off, telemedically speaking, since then. Well, NASA may have heated them up again. Or maybe it was Starfleet. Hmm, wait a second while we check. … No, it was NASA.

Thomas Pesquet/ESA

The space agency used the Microsoft Hololens Kinect camera and a personal computer with custom software from Aexa Aerospace to “holoport” NASA flight surgeon Josef Schmid up to the International Space Station, where he had a conversation with European Space Agency astronaut Thomas Pesquet, who wore an augmented reality headset that allowed him to see, hear, and interact with a 3D representation of the earthbound medical provider.

“Holoportation has been in use since at least 2016 by Microsoft, but this is the first use in such an extreme and remote environment such as space,” NASA said in a recent written statement, noting that the extreme house call took place on Oct. 8, 2021.

They seem to be forgetting about Star Trek, but we’ll let them slide on that one. Anyway, NASA didn’t share any details of the medical holoconversation – which may have strained the limits of HIPAA’s portability provisions – but Dr. Schmid described it as “a brand-new way of human exploration, where our human entity is able to travel off the planet. Our physical body is not there, but our human entity absolutely is there.”

Boldly doctoring where no doctor has gone before, you might say. You also might notice from the photo that Dr. Schmid went full Trekkie with a genuine Vulcan salute. Live long and prosper, Dr. Schmid. Live long and prosper.
 

Add electricity for umami

Salt makes everything taste better. Unfortunately, excess salt can cause problems for our bodies down the line, starting with high blood pressure and continuing on to heart disease and strokes. So how do we enjoy our deliciously salty foods without putting ourselves at risk? One answer may be electricity.

OpenClipart-Vectors/Pixabay

Researchers at Meiji University in Tokyo partnered with food and beverage maker Kirin to develop a set of electric chopsticks to boost the taste of salt in foods without the extra sodium. According to codeveloper and Meiji University professor Homei Miyashita, the device, worn like a watch with a wire attached to one of the chopsticks, “uses a weak electrical current to transmit sodium ions from food, through the chopsticks, to the mouth where they create a sense of saltines,” Reuters said.

In a country like Japan, where a lot of food is made with heavily sodium-based ingredients like miso and soy sauce, the average adult consumes 10 g of salt a day. That’s twice the recommended amount proposed by the World Health Organization. To not sacrifice bland food for better health, this device, which enhances the saltiness of the food consumed by 1.5 times, offers a fairly easy solution to a big public health crisis.

The chopsticks were tested by giving participants reduced-sodium miso soup. They told the researchers that the food was improved in “richness, sweetness, and overall tastiness,” the Guardian said.

Worried about having something electric in your mouth? Don’t worry. Kirin said in a statement that the electricity is very weak and not enough to affect the body.

The chopsticks are still in a prototype stage, but you may be able to get your pair as soon as next year. Until then, maybe be a little mindful of the salt.
 

Pet poop works in mysterious ways

We usually see it as a burden when our pets poop and pee in the house, but those bodily excretions may be able to tell us something about cancer-causing toxins running rampant in our homes.

Those toxins, known as aromatic amines, can be found in tobacco smoke and dyes used in make-up, textiles, and plastics. “Our findings suggest that pets are coming into contact with aromatic amines that leach from products in their household environment,” lead author Sridhar Chinthakindi, PhD, of NYU Langone Health, said in a statement from the university. “As these substances have been tied to bladder, colorectal, and other forms of cancer, our results may help explain why so many dogs and cats develop such diseases.”

Tobacco smoke was not the main source of the aromatic amines found in the poop and urine, but 70% of dogs and 80% of cats had these chemicals in their waste. The researchers looked for 30 types of aromatic amines plus nicotine in the sample and found 8. The chemical concentrations were much higher in cats than in dogs, possibly because of differences in exposure and metabolism between the two species, they suggested.

“If [pets] are getting exposed to toxins in our homes, then we had better take a closer look at our own exposure,” said senior author Kurunthachalam Kannan, PhD, of NYU Langone.

So the next time your pet poops or pees in the house, don’t get mad. Maybe they’re just trying to help you out by supplying some easy-to-collect samples.

Can’t sleep? When slumber doesn’t come naturally, some are turning to melatonin, an over-the-counter sleep aid that often is mistaken for a supplement. This powerful hormone plays an important role in human biology, and specialists are questioning whether increasing levels could be doing more harm than good.

A new investigation launched by the American Academy of Sleep Medicine is looking into the safety of melatonin. And while the health advisory checking the evidence is underway, the academy is recommending that melatonin not be used for insomnia in adults or children.

But what is insomnia, and how is it different from a few bad nights of sleep? Insomnia disturbs sleep at least three times a week for more than 3 months, often causing people to feel tired during the day as well.

Production of melatonin (dubbed the “vampire hormone”) begins at night, when it starts getting dark outside. Melatonin release is scheduled by the small but mighty pineal gland at the back of the head. Melatonin signals to the body that it’s time to sleep. And as the sun rises and light shines, melatonin levels decline again to help the body wake.

Sometimes packaged in gummy bear fruit flavors, melatonin can have an alluring appeal to sleep-deprived parents looking for relief for themselves and their children.

Muhammad Adeel Rishi, MD, vice chair of the public safety committee for the American Academy of Sleep Medicine, said he has a doctor colleague who started taking melatonin to help him during the pandemic when he was having trouble falling asleep at night. His doctor friend started giving the hormone to his own children, who were also having sleep issues.

But Dr. Rishi said there are important reasons to not use melatonin for insomnia until more information is available.

Melatonin affects sleep, but this hormone also influences other functions in the body. “It has an impact on body temperature, blood sugar, and even the tone of blood vessels,” Dr. Rishi said.

And because melatonin is available over the counter in the United States, it hasn’t been approved as a medicine under the Food and Drug Administration. A previous study of melatonin products, for instance, flagged problems with inconsistent doses, which make it hard for people to know exactly how much they are getting and prompted calls for more FDA oversight.
 

Imprecise doses

While melatonin doses typically range from 1 to 5 milligrams, bottles examined have been off target with much more or less hormone in the product than listed on the label.

Researchers from the University of Guelph (Ont.), tested 30 commercially available formulas and found the melatonin content varied from the ingredients labeled on the bottles by more than 10%. In addition to melatonin, the researchers found other substances in the bottles too: In about a quarter of the products, they also identified serotonin.
 

Impurities

While melatonin plays a role in setting the body’s biological clock and the sleep and wake cycle, serotonin is also at work. Occurring naturally in our bodies, serotonin is involved in mood and helps with deep REM sleep. But adding serotonin in unknown amounts could be unhealthy.

Dr. Rishi said it can be dangerous to use a product as a medication when doses can be so off and there are unknown byproducts in it.

Serotonin can influence the heart, blood vessels, and brain, so it’s not something Dr. Rishi wants to see people taking without paying attention. People taking medication for mood disorders could be especially affected by the serotonin in their sleep aid, he warns.

For anyone taking melatonin, Dr. Rishi recommended they check the bottle to see whether they are using a product with a USP-verified check mark, which indicates that the product meets the standards of the U.S. Pharmacopeia Convention.

The risk of impurities is a good reason for kids to not be given the hormone, but another worry is whether melatonin interferes with puberty in children – which is also a question researchers at the Children’s Hospital of Eastern Ontario in Ottawa are asking.
 

Disrupting puberty

While short-term melatonin use is considered safe, the researchers reported, concerns that long-term use might delay children’s sexual maturation require more study. One theory is that nightly melatonin use might interrupt the decline of natural hormone levels and interfere with the start of puberty.

Researchers from the Children’s Hospital of Michigan in Detroit also reported an uptick in accidental ingestion of melatonin in children. Kids got their hands on melatonin and swallowed too many capsules more often than other pill-related mishaps during the pandemic.

Dr. Rishi said more research is needed to assess the safe use of melatonin in children. He points out that the hormone can treat circadian rhythm disorders in adults.

While specialists weigh the benefits and risks of melatonin use and where it is safest to try, Dr. Rishi said the hormone does have a role in medicine.

Melatonin will probably need to be regulated by the FDA as a medication – especially for children – Dr. Rishi pointed out. And what place, if any, it will have for managing chronic insomnia is “a big question mark.”

Results of the investigation by the American Academy of Sleep Medicine will be published on its sleepeducation.org website in a few months.

The risk of impurities is a good reason for kids to not be given the hormone, but another worry is whether melatonin interferes with puberty in children – which is also a question researchers at the Children’s Hospital of Eastern Ontario in Ottawa are asking.
 

Disrupting puberty

While short-term melatonin use is considered safe, the researchers reported, concerns that long-term use might delay children’s sexual maturation require more study. One theory is that nightly melatonin use might interrupt the decline of natural hormone levels and interfere with the start of puberty.

Researchers from the Children’s Hospital of Michigan in Detroit also reported an uptick in accidental ingestion of melatonin in children. Kids got their hands on melatonin and swallowed too many capsules more often than other pill-related mishaps during the pandemic.

Dr. Rishi said more research is needed to assess the safe use of melatonin in children. He points out that the hormone can treat circadian rhythm disorders in adults.

While specialists weigh the benefits and risks of melatonin use and where it is safest to try, Dr. Rishi said the hormone does have a role in medicine.

Melatonin will probably need to be regulated by the FDA as a medication – especially for children – Dr. Rishi pointed out. And what place, if any, it will have for managing chronic insomnia is “a big question mark.”

Results of the investigation by the American Academy of Sleep Medicine will be published on its sleepeducation.org website in a few months.

Heartland virus (HRTV), an emerging infection first detected in lone star ticks in Missouri in 2009, has spread to lone star ticks in Georgia, a study published in Emerging Infectious Diseases reports.

HRTV disease is transmitted by the bite of an infected Amblyomma americanum tick, named “lone star” because of the silver-white spot on the female scutum (back).

“By … sampling … in an area with reported exposure to HRTV in wildlife and humans and testing for infection in thousands of ticks from multiple sites and physiologic stages, we confirmed the presence of HRTV in Georgia,” the authors write.

“This information about the expanding geographic range of lone star ticks, combined with increased human presence in tick-infested habitats, can be used to improve strategies for preventing tick bites and to alert physicians about this emerging tickborne virus infection,” a press release by the Centers for Disease Control and Prevention notes.
 

Persistent field and lab work led to HRTV discovery in Georgia

The search for infected lone star ticks began after a retroactive analysis confirmed that a person who died in Georgia in 2005 from an unidentified illness was infected with HRTV. A subsequent analysis of serum samples collected earlier from local white-tailed deer showed that the deer had been exposed to HRTV since at least 2001, according to a press release by Emory University.

These discoveries prompted local researchers to investigate whether lone star ticks in rural, woodsy central Georgia were carrying HRTV.

Lead study author Yamila Romer, MD, an infectious disease clinician and microbiologist in the department of environmental sciences at Emory University in Atlanta, and her colleagues collected samples of ticks in 2018 at 26 sites near the location of the patient who died and the seropositive deer. In 2019, they focused their collections on the two sites that had provided the most ticks in 2018.

From April to October in both years, the research team visited sites weekly to swish white flannel flags through underbrush. They picked off adult and nymph Amblyomma americanum ticks, placed them into vials, and transported them to their lab. They sorted 9,294 ticks by sex, life stage, and collection site. Then they crushed the ticks and extracted their RNA.

To confirm viral infection, the team tested RNA extracted from cell culture supernatants using a real-time polymerase chain reaction test specific for HRTV.

In the three pools of ticks that tested positive for HRTV, the researchers found a minimum infection rate of 0.46/1,000 ticks, suggesting that about 1 of every 2,000 ticks carried HRTV. They sequenced the genome of the three isolates and found that the genomes were similar to one another but were very different from the genomes from HRTV samples taken outside Georgia.

Catherine A. Hill, PhD, a professor of entomology and vector biology and the interim head of the department of entomology at Purdue University in West Lafayette, Ind., was impressed with the researchers’ discovery.

“Heartland virus is difficult to detect,” she said in an email. “The prevalence of human cases is low, and the virus appears to be present at very low levels in populations of lone star tick. The investigators went to some lengths to survey for the virus, collect, and process thousands of ticks – and they found the needle in the haystack.” Dr. Hill was not involved in the study.
 

Georgia data help researchers monitor HRTV spread

HRTV was first identified in 2009 in Missouri in two people hospitalized with fever, muscle pain, diarrhea, and low white blood cell and platelet counts. Researchers traced the infections to lone star ticks, and they found antibodies to the virus in blood samples from deer and other wild mammals.

According to the CDC, U.S. cases of tick-borne diseases more than doubled between 2004 and 2016. As of January 2021, more than 50 human cases of HRTV disease had been reported in 11 Midwestern and Southeastern states: Arkansas, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Missouri, North Carolina, Oklahoma, and Tennessee.
 

Precautions, signs, symptoms, testing, and treatment

“The lone star tick is aggressive and will actively seek out a human host to bite,” Dr. Hill noted.

She recommends that health care providers advise patients to avoid tick habitat, wear protective clothing, apply repellants, know the signs and symptoms of tick-borne disease, and seek immediate medical care if they become ill.

Common symptoms of HRTV disease include fatigue, fever, nausea, diarrhea, and anorexia. Treatment is supportive. Many patients have been hospitalized, and some with comorbidities have died.

HRTV infection is rarely tested for, and the disease burden is unknown. With no commercial tests available in the United States, the CDC performs molecular and serologic testing for HRTV infection. The agency advises doctors to contact their state health department if they suspect a patient may have HRTV disease.
 

Further research is needed

Samantha M. Wisely, PhD, a professor of wildlife ecology and the director of the Cervidae Health Research Initiative at the University of Florida in Gainesville, was not surprised by the study finding.

“The more we look for heartland virus, the more places we find it,” Dr. Wisely told this news organization in an email.

“Little is known about which wildlife play a role in maintaining the virus on the landscape,” said Dr. Wisely, who was not involved in the study. “White-tailed deer have been shown to produce antibodies, meaning they have been exposed to the virus, but no one has actually found the virus in a wildlife species.”

The whole-genome sequencing of the virus was particularly important, Dr. Wisely explained. “Whole-genome data allow researchers to better understand viral evolution, pathogenicity, and viral dynamics across space and time – how it is evolving.”

The study was supported by a grant from the Emory University Research Council. The authors, Dr. Wisely, and Dr. Hill have disclosed no relevant financial relationships.

Difficult economic times and the unpredictable consequences of health care reform are making an increasing number of solo practitioners and small private groups very nervous. Yet, many balk at the prospect of selling to private equity companies. I have received many inquiries about other protective options, such as merging two or more small practices into one larger entity.

Merging offers many benefits: Better overall management, centralized and efficient billing and collection, group purchasing discounts, and reduced overhead, among others; but careful planning, and a written agreement, are essential. If you are considering such an option, here are some things to think about.

You should begin with an evaluation and comparison of the separate groups’ respective finances. This should include a history of production, collections, overhead, and liabilities. Basically, you want to locate and identify all assets and liabilities that will be combined into the new group. One area of immediate importance is Medicare participation. Which members now currently participate and which do not? Since the new group will need to have a single position, all of the physicians must agree on that issue.

Who will be in charge? Not every physician is a qualified manager. The manager should be the physician who is willing to spend the time it takes to sign checks, interact with the administrator, and ensure that other matters such as filing tax returns and approving minor purchases arc carried out properly.

What is the compensation formula? Compensation arrangements should be based on each physician’s current financial data and the goals of the practice. Will everyone be paid only for what they do individually, or will revenue be shared equally? I favor a combination, so productivity is rewarded but your income doesn’t drop to zero when you take time off.

Which practices have a retirement plan and which do not? Will you keep your retirement plans separate, or combine them? If the latter, you will have to agree on the terms of the new plan, which can be the same or different from any of the existing plans. You’ll probably need some legal guidance to insure that assets from existing plans can be transferred into a new plan without tax issues. You may also have to address the problem of physicians who currently do not have a plan who, for whatever reason, may not want to be forced into making retirement plan contributions.

The often-problematic issue of employees and their salaries needs to be addressed, to decide which employees will be needed in the new group, and to determine a salary structure. Each practice’s policies related to vacation, sick leave, and other such issues should be reviewed, and an overall policy for the new group developed.

Other common sticking points are issues related to facilities. If the practices intend to consolidate into one location, the physicians must decide which of the specific assets of each practice will be contributed to the new entity. Ideally, each party brings an equal amount of assets to the table, but in the real world that is hardly ever the case. Physicians whose assets are to be used generally want to be compensated, and those who have to dispose of or store assets are in a quandary. The solution to this predicament will vary depending on the circumstances of each merger. One alternative is to agree that any inequalities will be compensated at the other end, in the form of buyout value; that is, physicians contributing more assets will receive larger buyouts when they leave or retire than those contributing less.

Buyouts should be addressed in advance as well. You must decide when a buyout would occur – usually in the event of retirement, death, disability, or withdrawal (voluntary or involuntary) – how the buyout amount will be calculated, and how it will be paid. Then, you must agree on how a buyout amount will be valued. Remember that any buyout calculated at “appraised value” is a problem, because the buyout amount remains a mystery until an appraisal is performed. If the appraised value ends up being too high, the remaining owners may refuse to pay it. I suggest having an actuary create a formula, so that the buyout figure can be calculated at any time. This area, especially, is where you need experienced, competent legal advice.

Noncompete provisions are always a difficult issue, mostly because they are so hard (and expensive) to enforce. An increasingly popular alternative is, once again, to deal with it at the other end, with a buyout penalty. An unhappy partner can leave, and compete, but at the cost of a substantially reduced buyout. This permits competition, but discourages it; and it compensates the remaining partners.

These are only some of the pivotal business and legal issues that must be settled in advance. A little planning and negotiation can prevent a lot of grief, regret, and legal expenses in the future. I’ll discuss some other, more complicated merger options in my next column.

During the first year of the pandemic, at least four people in Michigan were infected with a coronavirus variant that has been found in mink.

The cluster, which previously included three cases, marks the first known instance of likely animal-to-human “spillover” of the virus in the United States, according to the New York Times. All four people fully recovered.

Two of the infected people were employees of a mink farm in Michigan that had an outbreak in October 2020. The other two people didn’t have known links to the farm, which may mean that the coronavirus variant among mink may have been circulating more widely among residents in that area during that time.

Virus samples from all four people contained two mutations that may show signs of an adaptation to mink. The mutations have also been documented in farmed mink in Europe and people with connections to those farms.

“This, in addition to the mink farmworkers testing positive for COVID-19 after the mink herd had begun experiencing illness and increased mortality, suggests that the most likely hypothesis is that the workers were infected after contact with mink on the farm,” Casey Barton Behravesh, DVM, who directs the Centers for Disease Control and Prevention’s One Health Office, told the newspaper.

But researchers are unable to prove the cause, she noted.

“Because there are few genetic sequences available from the communities around the farm, it is impossible to know for sure whether the mutations came from mink on the farm or were already circulating in the community,” she said.

In August 2020, the U.S. Department of Agriculture announced the first confirmed COVID-19 case in mink at farms in Utah, followed by a case in Wisconsin. Worldwide, the coronavirus has been detected in mink on farms in the Netherlands, Denmark, Poland, and Spain.

In early October 2020, Michigan officials announced that the coronavirus had been detected in mink on a local farm. Several of the animals had died. The CDC helped to investigate the outbreak by collecting samples from animals, farmworkers, and residents in the community.

By March 2021, the CDC had updated its website to note that a “small number of people” had contracted a coronavirus variant that “contained unique mink-related mutations.”

In April 2021, the Detroit Free Press and the Documenting COVID-19 project first reported on the first three cases – two farmworkers and a taxidermist who didn’t have a connection to the mink farm. This week, the news outlets reported an update that the fourth case was the taxidermist’s wife.

Earlier this month, National Geographic first reported on the fourth human case based on government documents about the mink farm outbreak.

Overall, animal-to-human transmission is rare, but the CDC is continuing to monitor potential coronavirus cases in wildlife, livestock, and zoo animals for new variants and virus reservoirs, the Times reported.

“These results highlight the importance of routinely studying the genetic material of SARS-CoV-2 in susceptible animal populations like mink, as well as in people,” the CDC wrote.

During the first year of the pandemic, at least four people in Michigan were infected with a coronavirus variant that has been found in mink.

The cluster, which previously included three cases, marks the first known instance of likely animal-to-human “spillover” of the virus in the United States, according to the New York Times. All four people fully recovered.

Two of the infected people were employees of a mink farm in Michigan that had an outbreak in October 2020. The other two people didn’t have known links to the farm, which may mean that the coronavirus variant among mink may have been circulating more widely among residents in that area during that time.

Virus samples from all four people contained two mutations that may show signs of an adaptation to mink. The mutations have also been documented in farmed mink in Europe and people with connections to those farms.

“This, in addition to the mink farmworkers testing positive for COVID-19 after the mink herd had begun experiencing illness and increased mortality, suggests that the most likely hypothesis is that the workers were infected after contact with mink on the farm,” Casey Barton Behravesh, DVM, who directs the Centers for Disease Control and Prevention’s One Health Office, told the newspaper.

But researchers are unable to prove the cause, she noted.

Emotional or sexual abuse in childhood may increase risk of multiple sclerosis (MS) in women, and risk may increase further with exposure to multiple kinds of abuse, according to the first prospective cohort study of its kind.

More research is needed to uncover underlying mechanisms of action, according to lead author Karine Eid, MD, a PhD candidate at Haukeland University Hospital, Bergen, Norway, and colleagues.

“Trauma and stressful life events have been associated with an increased risk of autoimmune disorders,” the investigators wrote in the Journal Of Neurology, Neurosurgery, & Psychiatry. “Whether adverse events in childhood can have an impact on MS susceptibility is not known.”

The present study recruited participants from the Norwegian Mother, Father and Child cohort, a population consisting of Norwegian women who were pregnant from 1999 to 2008. Of the 77,997 participating women, 14,477 reported emotional, sexual, and/or physical abuse in childhood, while the remaining 63,520 women reported no abuse. After a mean follow-up of 13 years, 300 women were diagnosed with MS, among whom 24% reported a history of childhood abuse, compared with 19% among women who did not develop MS.

To look for associations between childhood abuse and risk of MS, the investigators used a Cox model adjusted for confounders and mediators, including smoking, obesity, adult socioeconomic factors, and childhood social status. The model revealed that emotional abuse increased the risk of MS by 40% (hazard ratio [HR] 1.40; 95% confidence interval [CI], 1.03-1.90), and sexual abuse increased the risk of MS by 65% (HR 1.65; 95% CI, 1.13-2.39).

Although physical abuse alone did not significantly increase risk of MS (HR 1.31; 95% CI, 0.83-2.06), it did contribute to a dose-response relationship when women were exposed to more than one type of childhood abuse. Women exposed to two out of three abuse categories had a 66% increased risk of MS (HR 1.66; 95% CI, 1.04-2.67), whereas women exposed to all three types of abuse had the highest risk of MS, at 93% (HR 1.93; 95% CI, 1.02-3.67).

Dr. Eid and colleagues noted that their findings are supported by previous retrospective research, and discussed possible mechanisms of action.

“The increased risk of MS after exposure to childhood sexual and emotional abuse may have a biological explanation,” they wrote. “Childhood abuse can cause dysregulation of the hypothalamic-pituitary-adrenal axis, lead to oxidative stress, and induce a proinflammatory state decades into adulthood. Psychological stress has been shown to disrupt the blood-brain barrier and cause epigenetic changes that may increase the risk of neurodegenerative disorders, including MS.

“The underlying mechanisms behind this association should be investigated further,” they concluded.
 

Study findings should guide interventions

Commenting on the research, Ruth Ann Marrie, MD, PhD, professor of medicine and community health sciences and director of the multiple sclerosis clinic at Max Rady College of Medicine, Rady Faculty of Health Sciences, University of Manitoba, Winnipeg, said that the present study “has several strengths compared to prior studies – including that it is prospective and the sample size.”

Dr. Marrie, who was not involved in the study, advised clinicians in the field to take note of the findings, as patients with a history of abuse may need unique interventions.

“Providers need to recognize the higher prevalence of childhood maltreatment in people with MS,” Dr. Marrie said in an interview. “These findings dovetail with others that suggest that adverse childhood experiences are associated with increased mental health concerns and pain catastrophizing in people with MS. Affected individuals may benefit from additional psychological supports and trauma-informed care.”

Tiffany Joy Braley, MD, associate professor of neurology, and Carri Polick, RN and PhD candidate at the school of nursing, University of Michigan, Ann Arbor, who published a case report last year highlighting the importance of evaluating stress exposure in MS, suggested that the findings should guide interventions at both a system and patient level.

“Although a cause-and-effect relationship cannot be established by the current study, these and related findings should be considered in the context of system level and policy interventions that address links between environment and health care disparities,” they said in a joint, written comment. “Given recent impetus to provide trauma-informed health care, these data could be particularly informative in neurological conditions which are associated with high mental health comorbidity. Traumatic stress screening practices could lead to referrals for appropriate support services and more personalized health care.”

While several mechanisms have been proposed to explain the link between traumatic stress and MS, more work is needed in this area, they added.

This knowledge gap was acknowledged by Dr. Marrie.

“Our understanding of the etiology of MS remains incomplete,” Dr. Marrie said. “We still need a better understanding of mechanisms by which adverse childhood experiences lead to MS, how they interact with other risk factors for MS (beyond smoking and obesity), and whether there are any interventions that can mitigate the risk of developing MS that is associated with adverse childhood experiences.”

The investigators disclosed relationships with Novartis, Biogen, Merck, and others. Dr. Marrie receives research support from the Canadian Institutes of Health Research, the National Multiple Sclerosis Society, MS Society of Canada, the Consortium of Multiple Sclerosis Centers, Crohn’s and Colitis Canada, Research Manitoba, and the Arthritis Society; she has no pharmaceutical support. Dr. Braley and Ms. Polick reported no conflicts of interest.

A 35-year-old man comes to clinic for evaluation of new, severe headaches. He reports that these started 3 days ago. His headache is worse when he stands, and resolves when he lies down. Valsalva maneuver makes the headache much worse. The headaches are present in the occipital region. He also has noticed the onset of tinnitus. A physical exam reveals that his blood pressure is 110/70 mm Hg, his pulse is 60 beats per minute, and his temperature is 36.4° C. His standing BP is 105/60 mm Hg and standing pulse is 66 bpm. Both his neurologic exam and noncontrast head CT scan are normal.


Which of the following is the most likely diagnosis?

A) Subarachnoid hemorrhage

B) POTS (Postural orthostatic tachycardia syndrome)

C) Hypnic headache

D) Spontaneous intracranial hypotension (SIH)

E) Acoustic neuroma

The most likely cause for this patient’s headaches given his set of symptoms is spontaneous intracranial hypotension. Orthostatic headaches are common with POTS, but the absence of tachycardia with standing makes this diagnosis unlikely.

Spontaneous intracranial hypotension has symptoms that we are all familiar with in the post–lumbar puncture patient. In patients with post-LP headache, the positional nature makes it easy to diagnose. Patients who have had a lumbar puncture have a clear reason they have a cerebrospinal fluid (CSF) leak, leading to intracranial hypotension. Those with SIH do not.

Schievink summarized a lot of useful information in a review of patients with spontaneous intracranial hypotension.¹ The incidence is about 5/100,000, with the most common age around 40 years old. The most common symptom is orthostatic headache. The headache usually occurs within 15 minutes upon standing, and many patients have the onset of headache rapidly upon standing.

Usually the headache improves with lying down, and it is often brought on with Valsalva maneuver. Many patients report headaches that are worse in the second half of the day.

Orthostatic headache occurs in almost all patients with spontaneous intracranial hypotension, but in one series it occurred only in 77% of patients with SIH.² The patients who did not have typical headaches are more likely to have auditory symptoms such as tinnitus and muffled hearing.³

When you suspect SIH, appropriate workup is to start with brain MR imaging with contrast. Krantz and colleagues found dural enhancement was present in 83% of cases of SIH, venous distention sign in 75%, and brain sagging in 61%.⁴

About 10% of patients with SIH have normal brain imaging, so if the clinical features strongly suggest the diagnosis, moving on to spinal imaging with CT myelography or spinal MR are appropriate next steps.⁵

The causes of SIH are meningeal diverticula (usually in the thoracic or upper lumbar regions), ventral dural tears (usually from osteophytes), and cerebrospinal fluid–venous fistulas. Treatment of SIH has traditionally included a conservative approach of bed rest, oral hydration, and caffeine. The effectiveness of this is unknown, and, in one small series, 61% had headache symptoms at 6 months.⁶

Epidural blood patches are likely more rapidly effective than conservative therapy. In one study comparing the two treatments, Chung and colleagues found that 77% of the patients who received an epidural blood patch had complete headache relief at 4 weeks, compared with 40% of those who received conservative measures (P < .05).⁷
 

Clinical pearls

• Strongly consider SIH in patients with positional headache.
• Brain MR should be the first diagnostic test.

A) Subarachnoid hemorrhage

B) POTS (Postural orthostatic tachycardia syndrome)

C) Hypnic headache

D) Spontaneous intracranial hypotension (SIH)

E) Acoustic neuroma

The most likely cause for this patient’s headaches given his set of symptoms is spontaneous intracranial hypotension. Orthostatic headaches are common with POTS, but the absence of tachycardia with standing makes this diagnosis unlikely.

Spontaneous intracranial hypotension has symptoms that we are all familiar with in the post–lumbar puncture patient. In patients with post-LP headache, the positional nature makes it easy to diagnose. Patients who have had a lumbar puncture have a clear reason they have a cerebrospinal fluid (CSF) leak, leading to intracranial hypotension. Those with SIH do not.

Schievink summarized a lot of useful information in a review of patients with spontaneous intracranial hypotension.¹ The incidence is about 5/100,000, with the most common age around 40 years old. The most common symptom is orthostatic headache. The headache usually occurs within 15 minutes upon standing, and many patients have the onset of headache rapidly upon standing.

Usually the headache improves with lying down, and it is often brought on with Valsalva maneuver. Many patients report headaches that are worse in the second half of the day.

Orthostatic headache occurs in almost all patients with spontaneous intracranial hypotension, but in one series it occurred only in 77% of patients with SIH.² The patients who did not have typical headaches are more likely to have auditory symptoms such as tinnitus and muffled hearing.³

When you suspect SIH, appropriate workup is to start with brain MR imaging with contrast. Krantz and colleagues found dural enhancement was present in 83% of cases of SIH, venous distention sign in 75%, and brain sagging in 61%.⁴

About 10% of patients with SIH have normal brain imaging, so if the clinical features strongly suggest the diagnosis, moving on to spinal imaging with CT myelography or spinal MR are appropriate next steps.⁵

The causes of SIH are meningeal diverticula (usually in the thoracic or upper lumbar regions), ventral dural tears (usually from osteophytes), and cerebrospinal fluid–venous fistulas. Treatment of SIH has traditionally included a conservative approach of bed rest, oral hydration, and caffeine. The effectiveness of this is unknown, and, in one small series, 61% had headache symptoms at 6 months.⁶

Epidural blood patches are likely more rapidly effective than conservative therapy. In one study comparing the two treatments, Chung and colleagues found that 77% of the patients who received an epidural blood patch had complete headache relief at 4 weeks, compared with 40% of those who received conservative measures (P < .05).⁷
 

Clinical pearls

• Strongly consider SIH in patients with positional headache.
• Brain MR should be the first diagnostic test.
