A weighted blanket of approximately 12% body weight used at bedtime prompted the release of higher concentrations of melatonin, as measured in the saliva, compared with a lighter blanket of only about 2.4% of body weight.

This suggests that weighted blankets may help promote sleep in patients suffering from insomnia, according to the results from the small, in-laboratory crossover study.

“Melatonin is produced by the pineal gland and plays an essential role in sleep timing,” lead author Elisa Meth, PhD student, Uppsala University, Sweden, and colleagues observe.

“Using a weighted blanket increased melatonin concentration in saliva by about 30%,” Ms. Meth added in a statement.

“Future studies should investigate whether the stimulatory effect on melatonin secretion remains when using a weighted blanket over more extended periods,” the researchers observe, and caution that “it is also unclear whether the observed increase in melatonin is therapeutically relevant.”

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

Weighted blankets are commercially available at least in some countries in Scandinavia and Germany, as examples, and in general, they are sold for therapeutic purposes. And at least one study found that weighted blankets were an effective and safe intervention for insomnia in patients with major depressive disorder, bipolar disorder, generalized anxiety disorder, and attention deficit hyperactivity disorder and led to improvements in daytime symptoms and levels of activity.
 

Study done in healthy volunteers

The study involved a total of 26 healthy volunteers, 15 men and 11 women, none of whom had any sleep issues. “The day before the first testing session, the participants visited the laboratory for an adaptation night,” the authors observe. There were two experimental test nights, one in which the weighted blanket was used and the second during which the lighter blanket was used.

On the test nights, lights were dimmed between 9 PM and 11 PM and participants used a weighted blanket covering the extremities, abdomen, and chest 1 hour before and during 8 hours of sleep. As the authors explain, the filling of the weighted blanket consisted of honed glass pearls, combined with polyester wadding, which corresponded to 12.2% of participants’ body weight.

“Saliva was collected every 20 minutes between 22:00 and 23:00,” Ms. Meth and colleagues note. Participants’ subjective sleepiness was also assessed every 20 minutes using the Karolinska Sleepiness Scale both before the hour that lights were turned off and the next morning.

“Sleep duration in each experimental night was recorded with the OURA ring,” investigators explain.

The OURA ring is a commercial multisensor wearable device that measures physiological variables indicative of sleep. Investigators focused on total sleep duration as the primary outcome measure.

On average, salivary melatonin concentrations rose by about 5.8 pg/mL between 10 PM and 11 PM (P < .001), but the average increase in salivary melatonin concentrations was greater under weighted blanket conditions at 6.6 pg/mL, compared with 5.0 pg/mL during the lighter blanket session (P = .011).

Oxytocin in turn rose by about 315 pg/mL initially, but this rise was only transient, and over time, no significant difference in oxytocin levels was observed between the two blanket conditions. There were also no differences in cortisol levels or the activity of the sympathetic nervous system between the weighted and light blanket sessions.

Importantly, as well, no significant differences were seen in the level of sleepiness between participants when either blanket was used nor was there a significant difference in total sleep duration.

“Our study cannot identify the underlying mechanism for the observed stimulatory effects of the weighted blanket on melatonin,” the investigators caution.

However, one explanation could be that the pressure exerted by the weighted blanket activates cutaneous sensory afferent nerves, carrying information to the brain. The region where the sensory information is delivered stimulates oxytocinergic neurons that can promote calm and well-being and decrease fear, stress, and pain. In addition, these neurons also connect to the pineal gland to influence the release of melatonin, the authors explain.
 

Melatonin often viewed in the wrong context

Senior author Christian Benedict, PhD, associate professor of pharmacology, Uppsala University, Sweden, explained that some people think of melatonin in the wrong context.

In point of fact, “it’s not a sleep-promoting hormone. It prepares your body and brain for the biological night ... [and] sleep coincides with the biological night, but it’s not like you take melatonin and you have a very nice uninterrupted slumber – this is not true,” he told this news organization.

He also noted that certain groups respond to melatonin better than others. For example, children with attention deficit hyperactivity disorder may have some benefit from melatonin supplements, as may the elderly who can no longer produce sufficient amounts of melatonin and for whom supplements may help promote the timing of sleep.

However, the bottom line is that, even in those who do respond to melatonin supplements, they likely do so through a placebo effect that meta-analyses have shown plays a powerful role in promoting sleep. 

Dr. Benedict also stressed that just because the body makes melatonin, itself, does not mean that melatonin supplements are necessarily “safe.”

“We know melatonin has some impact on puberty – it may delay the onset of puberty – and we know that it can also impair blood glucose, so when people are eating and have a lot of melatonin on board, the melatonin will tell the pancreas to turn off insulin production, which can give rise to hyperglycemia,” he said.

However, Dr. Benedict cautioned that weighted blankets don’t come cheap. A quick Google search brings up examples that cost upwards of $350. “MDs can say try one if you can afford these blankets, but perhaps people can use several less costly blankets,” he said. “But I definitely think if there are cheap options, why not?” he concluded.

Dr. Benedict has reported no relevant financial relationships.

What could you do with $18 billion?

I could pay off my mortgage roughly 60,000 times, or take my wife on a never-ending world cruise so we don’t need a mortgage, or at least hire someone to clean my pool regularly so I don’t have to.

A recent report from the OIG found that, in the last 3 years, the Centers for Medicare & Medicaid Services spent $18 billion on drugs for which there’s no proof of significant clinical benefit.

That’s a lot of money on things that may or may not be placebos, some of which are WAY overdue on Food and Drug Administration–mandated efficacy studies. A few have even been on the market so long that they’ve become equally unproven generics.

Now, if you put this in the big picture, that immense amount of money is still only 2% of their total spending in health care. Hell, probably at least 2% of my personal spending is on pointless things, too. So, realistically, you could say 98% of CMS spending is on worthwhile care, which is as it should be.

But the bottom line is that $18 billion is still a lot of money if it’s being spent on fruitless treatments. I’m sure it could be better used in many other programs (refunding it to taxpayers comes out to maybe $55 for each of us, which probably isn’t worth the effort).

As pointed out in the movie “Dave,” shoving that kind of money in even a low-yield savings account would generate at least $180 million in interest each year.

That’s a lot of money, too, that could be used for something. Of course, no one in the government thinks that way. That’s why we all loved the movie.

The problem is that the phrase “no proof of significant clinical benefit” doesn’t mean something doesn’t work. It just means we aren’t sure. Some of those people on one of these drugs may be getting benefit – or not. After all, the placebo effect is remarkably strong. But if they are helping someone, who wants to be the one to tell them “we’re not going to pay for this anymore?”

Another issue is this: Let’s say the drugs only work for 10% of the people who take them ($1.8 billion worth), and for the other 90% it’s iffy ($16.2 billion worth), but the latter want to stay on them anyway, just to be sure. Do we cut them? Or just say that $18 billion is too much money when only 10% are being helped, and cut them all off? I’m sure we could use the money elsewhere (see “Dave” above), so let them find a way to work it out with the manufacturer. The greatest good for the greatest number and all that jazz.

I don’t know, either. Health care dollars are finite, and human suffering is infinite. It’s a balancing act that can’t be won. There are no easy answers.

Revised ICD-10-CM codes for neurocognitive disorders are now in effect, the American Psychiatric Association has announced

The coding changes for major and mild neurocognitive disorders represent “the most consequential” coding changes for DSM-5 disorders since the Oct. 1, 2015, changeover from ICD-9-CM to ICD-10-CM,” Michael First, MD, professor of clinical psychiatry at Columbia University, in New York, wrote in a statement published in Psychiatric News.

The updated codes for neurocognitive disorders are “much more specific and indicate all the different types of behavioral problems that could occur with dementia,” First, who served as editor of the DSM-5-TR, added in an interview.

This year, coding changes that affect psychiatry are largely confined to major and mild neurocognitive disorders, but they represent “a big switch-over,” Dr. First said.
 

What’s new

The first three characters that make up the ICD-10-CM code for major neurocognitive disorder depend on the type of etiologic medical condition and are unchanged:

• F01 for major neurocognitive disorder caused by vascular disease
• F02 for major neurocognitive disorder caused by other medical conditions in which the specific etiologic medical condition is indicated by also listing the ICD-10-CM code for the medical condition
• F03 for major neurocognitive disorder when the medical etiology is unknown

However, DSM-5-TR diagnostic criteria for major neurocognitive disorder include severity specifiers (mild, moderate, severe), but there is no provision for indicating this “clinically important” information in the current ICD-10-CM code for major neurocognitive disorder, Dr. First explained.

The 2022 coding changes for major neurocognitive disorder include the provision of a fourth character code to indicate the severity of the major neurocognitive disorder – “A” indicates mild (difficulties with instrumental activities of daily living, such as housework and managing money); “B,” moderate (difficulties with basic activities of daily living, such as feeding and dressing); and “C,” severe (fully dependent) impairment.

The coding changes for major neurocognitive disorder also now include fifth and sixth characters to indicate the presence of an accompanying behavioral or psychological disturbance, such as agitation, psychotic disturbance, mood symptoms, and anxiety.

The update, which went into effect Oct. 1, also adds to ICD-10-CM two new mental disorder codes, F06.71 and F06.70 for mild neurocognitive disorder caused by a medical condition with or without a behavioral disturbance, respectively.

The coding changes affecting psychiatry are outlined in the APA’s 2022 DSM-5-TR Update: Supplement to the Diagnostic and Statistical Manual of Mental Disorders and DSM-5-TR Neurocognitive Disorders Supplement.
 

Annual event

Every Oct. 1, ICD-10-CM codes for all of medicine are updated, with new codes being added and others revised or deleted. Only a small fraction of the 68,000 codes is affected. Last year, 159 new codes were added, 25 codes were deleted, and 27 existing codes were revised.

All HIPAA-compliant health care entities are required to use the most up-to-date ICD-10-CM codes.

“I think there’s a grace period where you can still use the old codes, but there will be a point where if you use the old code, it’ll get rejected because it won’t be considered a valid code,” said Dr. First.

The coding changes affecting psychiatry are outlined in the APA’s 2022 DSM-5-TR Update: Supplement to the Diagnostic and Statistical Manual of Mental Disorders and DSM-5-TR Neurocognitive Disorders Supplement.
 

Annual event

Every Oct. 1, ICD-10-CM codes for all of medicine are updated, with new codes being added and others revised or deleted. Only a small fraction of the 68,000 codes is affected. Last year, 159 new codes were added, 25 codes were deleted, and 27 existing codes were revised.

All HIPAA-compliant health care entities are required to use the most up-to-date ICD-10-CM codes.

“I think there’s a grace period where you can still use the old codes, but there will be a point where if you use the old code, it’ll get rejected because it won’t be considered a valid code,” said Dr. First.

Incentive bonuses have long been part and parcel of many physicians’ compensation packages. They allow doctors in some specialties to boost their compensation by tens of thousands of dollars.

Often tied to metrics that doctors must hit, incentive bonuses aren’t without controversy. Some physicians welcome them. Others feel burdened by them or think that metrics distract from best patient care.

A recent Medscape poll asked what physicians think about incentive bonuses and whether or not tying metrics to salary is an outdated practice that interferes with the integrity of a physician’s job or contributes to excellence in patient care and increased productivity.

Here is what 406 physicians who answered the poll, which ran from Aug. 17 to Sept. 1, had to say about incentive bonuses:

More than half the physicians polled (58%) received an incentive bonus in 2021. Of those who received a bonus, 44% received up to $25,000. Almost 30% received $25,001-$50,000 in incentive bonus money. Only 14% received more than $100,000.

When we asked physicians which metrics they prefer their bonus to be based on, a large majority (64%) agreed quality of care was most relevant. Other metrics that respondents think appropriate included professionalism (40%), patient outcomes (40%), patient satisfaction (34%), patient volume (26%), market expansion (7%), and other (3%).
 

The problem with bonuses

Once thought to improve quality and consistency of care, incentive bonuses may be falling out of favor. Developing, administrating, and tracking them may be cumbersome for the institutions that advocate for them. For instance, determining who gave quality care and how to measure that care can be difficult.

What’s more, some top health care employers, Mayo Clinic and Kaiser Permanente, have switched from the incentive bonus model to straight salaries. Data show that the number of tests patients have and the number of treatments they try decreases when doctors receive straight salaries. 

In fact, 74% of the polled physicians think that bonuses can result in consequences like unnecessary tests and higher patient costs. Three-fourths of respondents don’t think incentives improve patient care either.

Physicians have long thought incentive bonuses can also have unintended consequences. For example, tying a physician’s monetary reward to metrics such as patient outcomes, like adherence to treatment protocols, may mean that noncompliant patients can jeopardize your metrics and prevent physicians from getting bonuses.

A Merritt Hawkins’ 2019 Review of Physician and Advanced Practitioner Recruiting Incentives found that 56% of bonuses are based in whole or in part on metrics like a patient’s adherence.

Additionally, tying monetary rewards to patient volume encourages some physicians to overbook patients, work more and longer hours, and risk burnout to meet their bonus criteria.

When we asked how hard it was to meet metrics in the Medscape poll, 45% of respondents who receive incentive bonuses said it was somewhat or very difficult. Only 9% consider it very easy. And 71% of physicians say their bonus is at risk because of not meeting their metrics.

Not surprisingly, large pay-for-performance bonuses are only offered to certain specialists and physician specialties in high demand. An orthopedist, for example, can earn up to an average of $126,000 in incentive bonuses, while a pediatrician brings in an average of $28,000, according to the Medscape Physician Compensation Report 2022.

Yet physicians are still torn

Despite these negatives, physicians are split about whether bonuses are good for doctors. The poll shows 51% said no, and 49% said yes. Further, physicians were split 50-50 on whether the bonus makes physicians more productive. Interestingly though, 76% think the bonus compensation method should be phased out in favor of straight salaries.

But many physicians may welcome the “lump sum” nature of receiving large bonuses at certain times of the year to help pay off student loan debt or other expenses, or are just comfortable having a bonus.
 

Financially speaking

If you have the choice, you may fare better by taking a higher salary and eliminating a bonus. Receiving your pay throughout the year may be preferable to receiving large lump sums only at certain times. Another thing to remember about your incentive bonus is that they are sometimes taxed more heavily based on “supplemental income.” The IRS considers bonuses supplemental to your income, so they may have a higher withholding rate, which can feel penalizing. You may have noticed the extra withholding in your last bonus check.

As the United States enters a third fall with COVID-19, the virus for many is seemingly gone – or at least out of mind. But for those keeping watch, it is far from forgotten as deaths and infections continue to mount at a lower but steady pace.

What does that mean for the upcoming months? Experts predict different scenarios, some more dire than others – with one more encouraging.

In the United States, more than 300 people still die every day from COVID and more than 44,000 new daily cases are reported, according to the Centers for Disease Control and Prevention.

But progress is undeniable. The stark daily death tolls of 2020 have plummeted. Vaccines and treatments have dramatically reduced severe illness, and mask requirements have mostly turned to personal preference.

Epidemiologists and other medical experts laud the progress, but as they look at the maps and the numbers, they see several scenarios ahead that signal a coming wave of disease, among them more-resistant variants coupled with waning immunity, the potential for a “twindemic” with a flu/COVID onslaught, and underuse of lifesaving vaccines and treatments.
 

Variants loom/waning immunity

Omicron variant BA.5 still makes up about 80% of infections in the United States, followed by BA4.6, according to the CDC, but other subvariants are emerging and showing signs of resistance to current antiviral treatments.

Eric Topol, MD, founder and director of the Scripps Research Translational Institute in San Diego, said about COVID this fall: “There will be another wave, magnitude unknown.”

He said subvariants XBB and BQ.1.1 “have extreme levels of immune evasion and both could pose a challenge,” explaining that XBB is more likely to cause trouble than BQ.1.1 because it is even more resistant to natural or vaccine-induced immunity.

Dr. Topol pointed to new research on those variants in a preprint posted on bioRxiv. The authors’ conclusion: “These results suggest that current herd immunity and BA.5 vaccine boosters may not provide sufficiently broad protection against infection.” 

Another variant to watch, some experts say, is Omicron subvariant BA.2.75.2, which has shown resistance to antiviral treatments. It is also growing at a rather alarming rate, says Michael Sweat, PhD, director of the Medical University of South Carolina Center for Global Health in Charleston. That subvariant currently makes up under 2% of U.S. cases but has spread to at least 55 countries and 43 U.S. states after first appearing at the end of last year globally and in mid-June in the United States.

A non–peer-reviewed preprint study from Sweden found that the variant in blood samples was neutralized on average “at titers approximately 6.5 times lower than BA.5, making BA.2.75.2 the most [neutralization-resistant] variant evaluated to date.”

Katelyn Jetelina, PhD, assistant professor in the department of epidemiology at University of Texas Health Science Center, Houston, said in an interview the U.S. waves often follow Europe’s, and Europe has seen a recent spike in cases and hospitalizations not related to Omicron subvariants, but to weather changes, waning immunity, and changes in behavior.

The World Health Organization reported on Oct. 5 that, while cases were down in every other region of the world, Europe’s numbers stand out, with an 8% increase in cases from the week before. 

Dr. Jetelina cited events such as Oktoberfest in Germany, which ended in the first week of October after drawing nearly 6 million people over 2 weeks, as a potential contributor, and people heading indoors as weather patterns change in Europe.

Ali Mokdad, PhD, chief strategy officer for population health at the University of Washington, Seattle, said in an interview he is less worried about the documented variants we know about than he is about the potential for a new immune-escape variety yet to emerge.

“Right now we know the Chinese are gearing up to open up the country, and because they have low immunity and little infection, we expect in China there will be a lot of spread of Omicron,” he said. “It’s possible because of the number of infections we could see a new variant.”

Dr. Mokdad said waning immunity could also leave populations vulnerable to variants.

“Even if you get infected, after about 5 months, you’re susceptible again. Remember, most of the infections from Omicron happened in January or February 2022, and we had two waves after that,” he said.

The new bivalent vaccines tweaked to target some Omicron variants will help, Dr. Mokdad said, but he noted, “people are very reluctant to take it.”

Jennifer Nuzzo, DrPH, professor of epidemiology and director of the Pandemic Center at Brown University, Providence, R.I., worries that in the United States we have less ability this year to track variants as funding has receded for testing kits and testing sites. Most people are testing at home – which doesn’t show up in the numbers – and the United States is relying more on other countries’ data to spot trends.

“I think we’re just going to have less visibility into the circulation of this virus,” she said in an interview.
 

‘Twindemic’: COVID and flu

Dr. Jetelina noted Australia and New Zealand just wrapped up a flu season that saw flu numbers returning to normal after a sharp drop in the last 2 years, and North America typically follows suit.

“We do expect flu will be here in the United States and probably at levels that we saw prepandemic. We’re all holding our breath to see how our health systems hold up with COVID-19 and flu. We haven’t really experienced that yet,” she said.

There is some disagreement, however, about the possibility of a so-called “twindemic” of influenza and COVID.

Richard Webby, PhD, an infectious disease specialist at St. Jude Children’s Research Hospital in Memphis, said in an interview he thinks the possibility of both viruses spiking at the same time is unlikely.

“That’s not to say we won’t get flu and COVID activity in the same winter,” he explained, “but I think both roaring at the same time is unlikely.”

As an indicator, he said, at the beginning of the flu season last year in the Northern Hemisphere, flu activity started to pick up, but when the Omicron variant came along, “flu just wasn’t able to compete in that same environment and flu numbers dropped right off.” Previous literature suggests that when one virus is spiking it’s hard for another respiratory virus to take hold.
 

Vaccine, treatment underuse

Another threat is vaccines, boosters, and treatments sitting on shelves.

Dr. Sweat referred to frustration with vaccine uptake that seems to be “frozen in amber.”

As of Oct. 4, only 5.3% of people in the United States who were eligible had received the updated booster launched in early September.

Dr. Nuzzo said boosters for people at least 65 years old will be key to severity of COVID this season.

“I think that’s probably the biggest factor going into the fall and winter,” she said.

Only 38% of people at least 50 years old and 45% of those at least 65 years old had gotten a second booster as of early October.

“If we do nothing else, we have to increase booster uptake in that group,” Dr. Nuzzo said.

She said the treatment nirmatrelvir/ritonavir (Paxlovid, Pfizer) for treating mild to moderate COVID-19 in patients at high risk for severe disease is greatly underused, often because providers aren’t prescribing it because they don’t think it helps, are worried about drug interactions, or are worried about its “rebound” effect.

Dr. Nuzzo urged greater use of the drug and education on how to manage drug interactions.

“We have very strong data that it does help keep people out of hospital. Sure, there may be a rebound, but that pales in comparison to the risk of being hospitalized,” she said.
 

Calm COVID season?

Not all predictions are dire. There is another little-talked-about scenario, Dr. Sweat said – that we could be in for a calm COVID season, and those who seem to be only mildly concerned about COVID may find those thoughts justified in the numbers.

Omicron blew through with such strength, he noted, that it may have left wide immunity in its wake. Because variants seem to be staying in the Omicron family, that may signal optimism.

“If the next variant is a descendant of the Omicron lineage, I would suspect that all these people who just got infected will have some protection, not perfect, but quite a bit of protection,” Dr. Sweat said.

Dr. Topol, Dr. Nuzzo, Dr. Sweat, Dr. Webby, Dr. Mokdad, and Dr. Jetelina reported no relevant financial relationships.

Dr. Jetelina cited events such as Oktoberfest in Germany, which ended in the first week of October after drawing nearly 6 million people over 2 weeks, as a potential contributor, and people heading indoors as weather patterns change in Europe.

Ali Mokdad, PhD, chief strategy officer for population health at the University of Washington, Seattle, said in an interview he is less worried about the documented variants we know about than he is about the potential for a new immune-escape variety yet to emerge.

“Right now we know the Chinese are gearing up to open up the country, and because they have low immunity and little infection, we expect in China there will be a lot of spread of Omicron,” he said. “It’s possible because of the number of infections we could see a new variant.”

Dr. Mokdad said waning immunity could also leave populations vulnerable to variants.

“Even if you get infected, after about 5 months, you’re susceptible again. Remember, most of the infections from Omicron happened in January or February 2022, and we had two waves after that,” he said.

The new bivalent vaccines tweaked to target some Omicron variants will help, Dr. Mokdad said, but he noted, “people are very reluctant to take it.”

Jennifer Nuzzo, DrPH, professor of epidemiology and director of the Pandemic Center at Brown University, Providence, R.I., worries that in the United States we have less ability this year to track variants as funding has receded for testing kits and testing sites. Most people are testing at home – which doesn’t show up in the numbers – and the United States is relying more on other countries’ data to spot trends.

“I think we’re just going to have less visibility into the circulation of this virus,” she said in an interview.
 

‘Twindemic’: COVID and flu

Dr. Jetelina noted Australia and New Zealand just wrapped up a flu season that saw flu numbers returning to normal after a sharp drop in the last 2 years, and North America typically follows suit.

“We do expect flu will be here in the United States and probably at levels that we saw prepandemic. We’re all holding our breath to see how our health systems hold up with COVID-19 and flu. We haven’t really experienced that yet,” she said.

There is some disagreement, however, about the possibility of a so-called “twindemic” of influenza and COVID.

Richard Webby, PhD, an infectious disease specialist at St. Jude Children’s Research Hospital in Memphis, said in an interview he thinks the possibility of both viruses spiking at the same time is unlikely.

“That’s not to say we won’t get flu and COVID activity in the same winter,” he explained, “but I think both roaring at the same time is unlikely.”

As an indicator, he said, at the beginning of the flu season last year in the Northern Hemisphere, flu activity started to pick up, but when the Omicron variant came along, “flu just wasn’t able to compete in that same environment and flu numbers dropped right off.” Previous literature suggests that when one virus is spiking it’s hard for another respiratory virus to take hold.
 

Vaccine, treatment underuse

Another threat is vaccines, boosters, and treatments sitting on shelves.

Dr. Sweat referred to frustration with vaccine uptake that seems to be “frozen in amber.”

As of Oct. 4, only 5.3% of people in the United States who were eligible had received the updated booster launched in early September.

Dr. Nuzzo said boosters for people at least 65 years old will be key to severity of COVID this season.

“I think that’s probably the biggest factor going into the fall and winter,” she said.

Only 38% of people at least 50 years old and 45% of those at least 65 years old had gotten a second booster as of early October.

“If we do nothing else, we have to increase booster uptake in that group,” Dr. Nuzzo said.

She said the treatment nirmatrelvir/ritonavir (Paxlovid, Pfizer) for treating mild to moderate COVID-19 in patients at high risk for severe disease is greatly underused, often because providers aren’t prescribing it because they don’t think it helps, are worried about drug interactions, or are worried about its “rebound” effect.

Dr. Nuzzo urged greater use of the drug and education on how to manage drug interactions.

“We have very strong data that it does help keep people out of hospital. Sure, there may be a rebound, but that pales in comparison to the risk of being hospitalized,” she said.
 

Calm COVID season?

Not all predictions are dire. There is another little-talked-about scenario, Dr. Sweat said – that we could be in for a calm COVID season, and those who seem to be only mildly concerned about COVID may find those thoughts justified in the numbers.

Omicron blew through with such strength, he noted, that it may have left wide immunity in its wake. Because variants seem to be staying in the Omicron family, that may signal optimism.

“If the next variant is a descendant of the Omicron lineage, I would suspect that all these people who just got infected will have some protection, not perfect, but quite a bit of protection,” Dr. Sweat said.

Dr. Topol, Dr. Nuzzo, Dr. Sweat, Dr. Webby, Dr. Mokdad, and Dr. Jetelina reported no relevant financial relationships.

Tixagevimab copackaged with cilgavimab (Evusheld) is a safe and effective preexposure prophylaxis (PrEP) in patients undergoing B-cell-depleting therapies who have poor immune response to COVID-19 vaccination and are at high risk for serious COVID-19 illness, a small, single-site study suggests.

Evusheld, the only COVID-19 PrEP option available, has Emergency Use Authorization (EUA) from the Food and Drug Administration for treatment of immunocompromised patients who may not respond sufficiently to COVID-19 vaccination and patients who’ve had a severe adverse reaction to COVID-19 vaccination.

“We report the largest real-world experience of Evusheld in this population, and our findings are encouraging,” lead study author Cassandra Calabrese, DO, rheumatologist and infectious disease specialist at Cleveland Clinic, said in an interview.

“Of 412 patients who received Evusheld, 12 [2.9%] developed breakthrough COVID-19, with 11 having mild courses and 1 who required hospitalization but recovered,” she added.

“Our data suggest that Evusheld PrEP, in combination with aggressive outpatient treatment of COVID-19, is likely effective in lowering risk of severe COVID in this vulnerable group.

“Practitioners who care for patients with immune-mediated inflammatory diseases should triage high-risk patients for Evusheld as well as rapid diagnosis and aggressive outpatient therapy if infected,” Dr. Calabrese advised.

For the study, Dr. Calabrese and colleagues at Cleveland Clinic searched the health care system pharmacy records for patients with immune‐mediated inflammatory diseases (IMIDs) or inborn errors of humoral immunity (IEI) who met the criteria to receive Evusheld. The researchers included patients on B-cell-depleting therapies or with humoral IEI who had received at least one dose of Evusheld and were later diagnosed with COVID-19, and they excluded those treated with B-cell-depleting therapies for cancer.
 

EVUSHELD was well tolerated

After extracting data on COVID-19 infection, vaccination status, and outcomes, they found that, between Jan. 18 and May 28, 2022, 412 patients with IMIDs or humoral IEI received Evusheld. No deaths occurred among these patients and, overall, they tolerated the medication well.

All 12 patients who experienced breakthrough COVID-19 infection were treated with B-cell-depleting therapies. Among the 12 patients:

• Six patients developed infection 13-84 (median 19) days after receiving 150 mg/150 mg tixagevimab/cilgavimab.
• Six patients developed infection 19-72 (median of 38.5) days after either a single dose of 300 mg/300 mg or a second dose of 150 mg/150 mg.
• Eleven patients had mild illness and recovered at home; one patient was hospitalized and treated with high-flow oxygen. All cases had been vaccinated against COVID-19 (five received two vaccinations, six received three, and one received four).
• One possible serious adverse event involved a patient with COVID-19 and immune-mediated thrombocytopenia (ITP) who was hospitalized soon after receiving Evusheld with ITP flare that resolved with intravenous immunoglobulin.

Dr. Calabrese acknowledged limitations to the study, including few patients, lack of a comparator group, and the study period falling during the Omicron wave.

“Also, nine of the breakthrough cases received additional COVID-19 therapy (oral antiviral or monoclonal antibody), which falls within standard of care for this high-risk group but prevents ascribing effectiveness to individual components of the regimen,” she added.

“Evusheld is authorized for PrEP against COVID-19 in patients at high risk for severe COVID due to suboptimal vaccine responses. This includes patients receiving B-cell-depleting drugs like rituximab, and patients with inborn errors of humoral immunity,” Dr. Calabrese explained.

“It is well known that this group of patients is at very high risk for severe COVID and death, even when fully vaccinated, and it has become clear that more strategies are needed to protect this vulnerable group, including use of Evusheld as well as aggressive treatment if infected,” she added.  
 

Evusheld not always easy to obtain

Although the medication has been available in the United States since January 2022, Dr. Calabrese said, patients may not receive it because of barriers including lack of both awareness and access.

Davey Smith, MD, professor of medicine and head of infectious diseases and global public health at the University of California San Diego, in La Jolla, said in an interview that he was not surprised by the results, but added that the study was conducted in too few patients to draw any strong conclusions or affect patient care.

“This small study that showed that breakthrough infections occurred but were generally mild, provides a small glimpse of real-world use of tixagevimab/cilgavimab as PrEP for immunocompromised persons,” said Dr. Smith, who was not involved in the study.

“In the setting of Omicron and vaccination, I would expect the same outcomes reported even without the treatment,” he added.

Dr. Smith recommends larger related randomized, controlled trials to provide clinicians with sufficient data to guide them in their patient care.

Graham Snyder, MD, associate professor in the division of infectious diseases at the University of Pittsburgh and medical director of infection prevention and hospital epidemiology at the University of Pittsburgh Medical Center, noted that the study “adds to a quickly growing literature on the real-world benefits of tixagevimab/cilgavimab to protect vulnerable individuals with weakened immune systems from the complications of COVID-19.

“This study provides a modest addition to our understanding of the role and benefit of Evusheld,” Dr. Snyder said in an interview. “By characterizing only patients who have received Evusheld without an untreated comparison group, we can’t draw any inference about the extent of benefit the agent provided to these patients.

“Substantial data already show that this agent is effective in preventing complications of COVID-19 infection in immunocompromised individuals,” added Dr. Snyder, who was not involved in the study.

“ ‘Immunocompromised’ represents a very diverse set of clinical conditions,” he said. “The research agenda should therefore focus on a more refined description of the effect in specific populations and a continued understanding of the effect of Evusheld in the context of updated vaccination strategies and changing virus ecology.”

Dr. Calabrese and her colleagues wrote that larger, controlled trials are underway.

 

FDA: Evusheld may not neutralize certain SARS-CoV-2 variants

“The biggest unanswered question is how Evusheld will hold up against new variants,” Dr. Calabrese said.

In an Oct. 3, 2022, update, the Food and Drug Administration released a statement about the risk of developing COVID-19 from SARS-CoV-2 variants that are not neutralized by Evusheld. The statement mentions an updated fact sheet that describes reduced protection from Evusheld against the Omicron subvariant BA.4.6, which accounted for nearly 13% of all new COVID-19 cases in the United States in the week ending Oct. 1.

There was no outside funding for the study. Dr. Smith reported no relevant financial conflicts of interest. Dr. Snyder said he is an unpaid adviser to an AstraZeneca observational study that’s assessing the real-world effectiveness of Evusheld.

Unlike for many other professions, there is no age limit for practicing medicine. According to international standards, airplane pilots, for example, who are responsible for the safety of many human lives, must retire by the age of 60 if they work alone, or 65 if they have a copilot. In Brazil, however, this age limit does not exist for pilots or physicians.

The only restriction on professional practice within the medical context is the mandatory retirement imposed on medical professors who teach at public (state and federal) universities, starting at the age of 75. Nevertheless, these professionals can continue practicing administrative and research-related activities. After “expulsion,” as this mandatory retirement is often called, professors who stood out or contributed to the institution and science may receive the title of professor emeritus.

In the private sector, age limits are not formally set, but the hiring of middle-aged professionals is limited.

At the Heart Institute of the University of São Paulo (Brazil) School of Medicine Clinical Hospital (InCor/HCFMUSP), one of the world’s largest teaching and research centers for cardiovascular and pulmonary diseases, several octogenarian specialists lead studies and teams. One of these is Noedir Stolf, MD, an 82-year-old cardiovascular surgeon who operates almost every day and coordinates studies on transplants, mechanical circulatory support, and aortic surgery. There is also Protásio Lemos da Luz, MD, an 82-year-old clinical cardiologist who guides research on subjects including atherosclerosis, the endothelium, microbiota, and diabetes. The protective effect of wine on atherosclerosis is one of his best-known studies.

No longer working is also not in the cards for Angelita Habr-Gama, MD, who, at 89 years old, is one of the oldest physicians in current practice. With a career spanning more than 7 decades, she is a world reference in coloproctology. She was the first woman to become a surgical resident at the HCFMUSP, where she later founded the coloproctology specialty and created the first residency program for the specialty. In April 2022, Dr. Habr-Gama joined the ranks of the 100 most influential scientists in the world, nominated by researchers at Stanford (Calif.) University, and published in PLOS Biology.

In 2020, she was sedated, intubated, and hospitalized in the intensive care unit of the Oswaldo Cruz German Hospital for 54 days because of a SARS-CoV-2 infection. After her discharge, she went back to work in less than 10 days – and added chess classes to her routine. “To get up and go to work makes me very happy. Work is my greatest hobby. No one has ever heard me complain about my life,” Dr. Habr-Gama told this news organization after having rescheduled the interview twice because of emergency surgeries.

“Doctors have a professional longevity that does not exist for other professions in which the person retires and stops practicing their profession or goes on to do something else for entertainment. Doctors can retire from one place of employment or public practice and continue practicing medicine in the office as an administrator or consultant,” Ângelo Vattimo, first secretary of the state of São Paulo Regional Board of Medicine (CREMESP), stated. The board regularly organizes a ceremony to honor professionals who have been practicing for 50 years, awarding them a certificate and engraved medal. “Many of them are around 80 years old, working and teaching. This always makes us very happy. What profession has such exceptional compliance for so long?” said Mr. Vattimo.

In the medical field, the older the age range, the smaller the number of women. According to the 2020 Medical Demographics in Brazil survey, only 2 out of 10 practicing professionals older than 70 are women.

Not everyone over 80 has Dr. Habr-Gama’s vitality, because the impact of aging is not equal. “If you look at a group of 80-year-olds, there will be much more variability than within a group of 40-year-olds,” stated Mark Katlic, MD, chief of surgery at LifeBridge Health System in the United States, who has dedicated his life to studying the subject. Dr. Katlic spoke on the subject in an interview that was published in the article “How Old Is Too Old to Work as a Doctor?” published by this news organization in April of 2022. The article discusses the evaluations of elderly physicians’ skills and competences that U.S. companies conduct. The subject has been leading to profound debate.

Dr. Katlic defends screening programs for elderly physicians, which already are in effect at the company for which he works, LifeBridge Health, and various others in the United States. “We do [screen elderly physicians at LifeBridge Health], and so do a few dozen other [U.S. institutions], but there are hundreds [of health care institutions] that do not conduct this screening,” he pointed out.

Age-related assessment faces great resistance in the United States. One physician who is against the initiative is Frank Stockdale, MD, PhD, an 86-year-old practicing oncologist affiliated with Stanford (Calif.) University Health. “It’s age discrimination ... Physicians [in the United States] receive assessments throughout their careers as part of the accreditation process – there’s no need to change that as physicians reach a certain age,” Dr. Stockdale told this news organization.

The U.S. initiative of instituting physician assessment programs for those of a certain age has even been tested in court. According to an article published in Medscape, “in New Haven, Connecticut, for instance, the U.S. Equal Employment Opportunity Commission (EEOC) filed a suit in 2020 on behalf of the Yale New Haven Hospital staff, alleging a discriminatory late career practitioner policy.”

Also, according to the article, a similar case in Minnesota reached a settlement in 2021, providing monetary relief to staff impacted by out-of-pocket costs for the assessment, in addition to requiring that the hospital in question report to the EEOC any complaints related to age discrimination.

The fact is that increased life expectancy and, subsequently, the number of middle-aged physicians in practice, has raised several questions regarding the impact of aging on professional practice. In Brazil, the subject is of interest to more than 34,571 physicians between 65 and 69 years of age and 34,237 physicians older than 70. In all, this population represents approximately 14.3% of the country’s active workforce, according to the 2020 Medical Demographics in Brazil survey.

The significant participation of health care professionals over age 50 in a survey conducted by this news organization to learn what physicians think about the age limit for practicing their professions is evidence that the subject is a present concern. Of a total of 1,641 participants, 57% were age 60 or older, 17% were between 50 and 59 years, and 12% were between 40 and 49 years. Among all participants, 51% were against these limitations, 17% approved of the idea for all specialties, and 32% believed the restriction was appropriate only for some specialties. Regarding the possibility of older physicians undergoing regular assessments, the opinions were divided: Thirty-one percent thought they should be assessed in all specialties. Furthermore, 31% believed that cognitive abilities should be regularly tested in all specialties, 31% thought this should take place for some specialties, and 38% were against this approach.

Professionals want to know, for example, how (and whether) advanced age can interfere with performance, what are the competences required to practice their activities, and if the criteria vary by specialty. “A psychiatrist doesn’t have to have perfect visual acuity, as required from a dermatologist, but it is important that they have good hearing, for example,” argued Clóvis Constantino, MD, former president of the São Paulo Regional Medical Board (CRM-SP) and former vice president of the Brazilian Federal Medical Board (CFM). “However, a surgeon has to stand for several hours in positions that may be uncomfortable. It’s not easy,” he told this news organization.

In the opinion of 82-year-old Henrique Klajner, MD, the oldest pediatrician in practice at the Albert Einstein Israeli Hospital in São Paulo, the physician cannot be subjected to the types of evaluations that have been applied in the United States. “Physicians should conduct constant self-evaluations to see if they have the competences and skills needed to practice their profession ... Moreover, this is not a matter of age. It is a matter of ethics,” said Dr. Klajner.

The ability to adapt to change and implement innovation is critical to professional longevity, he said. “Nowadays, when I admit patients, I no longer do hospital rounds, which requires a mobility equal to physical abuse for me. Therefore, I work with physicians who take care of my hospitalized patients.”

Dr. Klajner also feels there is a distinction between innovations learned through studies and what can be offered safely to patients. “If I have to care for a hospitalized patient with severe pneumonia, for example, since I am not up to date in this specialty, I am going to call upon a pulmonologist I trust and forgo my honorarium for this admission. But I will remain on the team, monitoring the patient’s progression,” he said.

During the COVID-19 pandemic, Dr. Klajner stopped seeing patients in person under the recommendation of his son, Sidney Klajner, MD, also a physician. The elder Dr. Klajner began exploring telemedicine, which opened a whole new world of possibilities. “I have conducted several online visits to provide educational instruction to mothers returning home post delivery, for example,” he told this news organization. The time to stop is not something that concerns Dr. Klajner. “I’m only going to stop when I have a really important reason to do so. For example, if I can no longer write or study, reading and rereading an article without being able to understand what is being said. At this time, none of that is happening.”

In the United States, as well as in Brazil, physicians rarely provide information to human resources departments on colleagues showing signs of cognitive or motor decline affecting their professional performance. “The expectation is that health care professionals will report colleagues with cognitive impairments, but that often does not happen,” Dr. Katlic said.

It is also not common for professionals to report their own deficits to their institutions. In large part, this is caused by a lack of well-defined policies for dealing with this issue. This news organization sought out several public and private hospitals in Brazil to see if there is any guidance on professional longevity: Most said that there is not. Only the A. C. Camargo Cancer Center reported, through its public relations team, that a committee is discussing the subject but that it is still in the early stages.

Brazilian specialist associations do not offer guidelines or instructions on the various aspects of professional longevity. Dr. Constantino tried to put the subject on the agenda during the years in which he was an administrator with the CFM. “We tried to open up discussions regarding truly elderly physicians, but the subject was not well received. I believe that it is precisely because there is a tradition of physicians working until they are no longer able that this is more difficult in Brazil ... No one exactly knows what to do in this respect.” Dr. Constantino is against the use of age as a criterion for quitting practice.

“Of course, this is a point that has to be considered, but I always defended the need for regular assessment of physicians, regardless of age range. And, although assessments are always welcome, in any profession, I also believe this would not be well received in Brazil.” He endorses an assessment of one’s knowledge and not of physical abilities, which are generally assessed through investigation when needed.

The absence of guidelines increases individual responsibility, as well as vulnerability. “Consciously, physicians will not put patients at risk if they do not have the competence to care for them or to perform a surgical procedure,” said Clystenes Odyr Soares Silva, MD, PhD, adjunct professor of pulmonology of the Federal University of São Paulo (Brazil) School of Medicine (UNIFESP). “Your peers will tell you if you are no longer able,” he added. The problem is that physicians rarely admit to or talk about their colleagues’ deficits, especially if they are in the spotlight because of advanced age. In this situation, the observation and opinion of family members regarding the health care professional’s competences and skills will hold more weight.

In case of health-related physical impairment, such as partial loss of hand movement, for example, “it is expected that this will set off an ethical warning in the person,” said Dr. Constantino. When this warning does not occur naturally, patients or colleagues can report the professional, and this may lead to the opening of an administrative investigation. If the report is found to be true, this investigation is used to suspend physicians who do not have the physical or mental ability to continue practicing medicine.

“If it’s something very serious, the physician’s license can be temporarily suspended while [the physician] is treated by a psychiatrist, with follow-up by the professional board. When discharged, the physician will get his or her [professional] license back and can go back to work,” Dr. Constantino explained. If an expert evaluation is needed, the physician will then be assessed by a forensic psychiatrist. One of the most in-demand forensic psychiatrists in Brazil is Guido Arturo Palomba, MD, 73 years old. “I have assessed some physicians for actions reported to see if they were normal people or not, but never for circumstances related to age,” Dr. Palomba said.

In practice, Brazilian medical entities do not have policies or programs to guide physicians who wish to grow old while they work or those who have started to notice they are not performing as they used to. “We have never lived as long; therefore, the quality of life in old age, as well as the concept of aging, are some of the most relevant questions of our time. These are subjects requiring additional discussion, broadening understanding and awareness in this regard,” observed Mr. Vattimo.

Dr. Constantino and Dr. Silva, who are completely against age-based assessments, believe that recertification of the specialist license every 5 years is the best path to confirming whether the physician is still able to practice. “A knowledge-based test every 5 years to recertify the specialist license has often been a topic of conversation. I think it’s an excellent idea. The person would provide a dossier of all they have done in terms of courses, conferences, and other activities, present it, and receive a score,” said Dr. Silva.

In practice, recertification of the specialist license is a topic of discussion that has been raised for years, and it is an idea that the Brazilian Medical Association (AMB) defends. In conjunction with the CFM, the association is studying a way to best implement this assessment. “It’s important to emphasize that this measure would not be retroactive at first. Instead, it would only be in effect for professionals licensed after the recertification requirement is established,” the AMB pointed out in a note sent to this news organization. Even so, the measure has faced significant resistance from a faction of the profession, and its enactment does not seem to be imminent.

The debate regarding professional longevity is taking place in various countries. In 2021, the American Medical Association Council on Medical Education released a report with a set of guidelines for the screening and assessment of physicians. The document is the product of a committee created in 2015 to study the subject. The AMA recommends that the assessment of elderly physicians be based on evidence and ethical, relevant, fair, equitable, transparent, verifiable, nonexhaustive principles, contemplating support and protecting against legal proceedings. In April of this year, a new AMA document highlighted the same principles.

Also in the United States, one of oldest initiatives created to support physicians in the process of recycling, the University of California San Diego Physician Assessment and Clinical Education Program (PACE), has a section focusing on the extended practice of medicine (Practicing Medicine Longer). For those wanting to learn more about discussions on this subject, there are online presentations on experiences in Quebec and Ontario with assessing aging physicians, neuropsychological perspectives on the aging medical population, and what to expect of healthy aging, among other subjects.

Created in 1996, PACE mostly provides services to physicians who need to address requirements of the state medical boards. Few physicians enroll on their own.

The first part of the program assesses knowledge and skills over approximately 2 days. In the second phase, the physician participates in a series of activities in a corresponding residency program. Depending on the results, the physician may have to go through a remedial program with varying activities to deal with performance deficiencies to clinical experiences at the residency level.

Unlike for many other professions, there is no age limit for practicing medicine. According to international standards, airplane pilots, for example, who are responsible for the safety of many human lives, must retire by the age of 60 if they work alone, or 65 if they have a copilot. In Brazil, however, this age limit does not exist for pilots or physicians.

The only restriction on professional practice within the medical context is the mandatory retirement imposed on medical professors who teach at public (state and federal) universities, starting at the age of 75. Nevertheless, these professionals can continue practicing administrative and research-related activities. After “expulsion,” as this mandatory retirement is often called, professors who stood out or contributed to the institution and science may receive the title of professor emeritus.

In the private sector, age limits are not formally set, but the hiring of middle-aged professionals is limited.

At the Heart Institute of the University of São Paulo (Brazil) School of Medicine Clinical Hospital (InCor/HCFMUSP), one of the world’s largest teaching and research centers for cardiovascular and pulmonary diseases, several octogenarian specialists lead studies and teams. One of these is Noedir Stolf, MD, an 82-year-old cardiovascular surgeon who operates almost every day and coordinates studies on transplants, mechanical circulatory support, and aortic surgery. There is also Protásio Lemos da Luz, MD, an 82-year-old clinical cardiologist who guides research on subjects including atherosclerosis, the endothelium, microbiota, and diabetes. The protective effect of wine on atherosclerosis is one of his best-known studies.

No longer working is also not in the cards for Angelita Habr-Gama, MD, who, at 89 years old, is one of the oldest physicians in current practice. With a career spanning more than 7 decades, she is a world reference in coloproctology. She was the first woman to become a surgical resident at the HCFMUSP, where she later founded the coloproctology specialty and created the first residency program for the specialty. In April 2022, Dr. Habr-Gama joined the ranks of the 100 most influential scientists in the world, nominated by researchers at Stanford (Calif.) University, and published in PLOS Biology.

In 2020, she was sedated, intubated, and hospitalized in the intensive care unit of the Oswaldo Cruz German Hospital for 54 days because of a SARS-CoV-2 infection. After her discharge, she went back to work in less than 10 days – and added chess classes to her routine. “To get up and go to work makes me very happy. Work is my greatest hobby. No one has ever heard me complain about my life,” Dr. Habr-Gama told this news organization after having rescheduled the interview twice because of emergency surgeries.

“Doctors have a professional longevity that does not exist for other professions in which the person retires and stops practicing their profession or goes on to do something else for entertainment. Doctors can retire from one place of employment or public practice and continue practicing medicine in the office as an administrator or consultant,” Ângelo Vattimo, first secretary of the state of São Paulo Regional Board of Medicine (CREMESP), stated. The board regularly organizes a ceremony to honor professionals who have been practicing for 50 years, awarding them a certificate and engraved medal. “Many of them are around 80 years old, working and teaching. This always makes us very happy. What profession has such exceptional compliance for so long?” said Mr. Vattimo.

In the medical field, the older the age range, the smaller the number of women. According to the 2020 Medical Demographics in Brazil survey, only 2 out of 10 practicing professionals older than 70 are women.

Not everyone over 80 has Dr. Habr-Gama’s vitality, because the impact of aging is not equal. “If you look at a group of 80-year-olds, there will be much more variability than within a group of 40-year-olds,” stated Mark Katlic, MD, chief of surgery at LifeBridge Health System in the United States, who has dedicated his life to studying the subject. Dr. Katlic spoke on the subject in an interview that was published in the article “How Old Is Too Old to Work as a Doctor?” published by this news organization in April of 2022. The article discusses the evaluations of elderly physicians’ skills and competences that U.S. companies conduct. The subject has been leading to profound debate.

Dr. Katlic defends screening programs for elderly physicians, which already are in effect at the company for which he works, LifeBridge Health, and various others in the United States. “We do [screen elderly physicians at LifeBridge Health], and so do a few dozen other [U.S. institutions], but there are hundreds [of health care institutions] that do not conduct this screening,” he pointed out.

Age-related assessment faces great resistance in the United States. One physician who is against the initiative is Frank Stockdale, MD, PhD, an 86-year-old practicing oncologist affiliated with Stanford (Calif.) University Health. “It’s age discrimination ... Physicians [in the United States] receive assessments throughout their careers as part of the accreditation process – there’s no need to change that as physicians reach a certain age,” Dr. Stockdale told this news organization.

The U.S. initiative of instituting physician assessment programs for those of a certain age has even been tested in court. According to an article published in Medscape, “in New Haven, Connecticut, for instance, the U.S. Equal Employment Opportunity Commission (EEOC) filed a suit in 2020 on behalf of the Yale New Haven Hospital staff, alleging a discriminatory late career practitioner policy.”

Also, according to the article, a similar case in Minnesota reached a settlement in 2021, providing monetary relief to staff impacted by out-of-pocket costs for the assessment, in addition to requiring that the hospital in question report to the EEOC any complaints related to age discrimination.

The fact is that increased life expectancy and, subsequently, the number of middle-aged physicians in practice, has raised several questions regarding the impact of aging on professional practice. In Brazil, the subject is of interest to more than 34,571 physicians between 65 and 69 years of age and 34,237 physicians older than 70. In all, this population represents approximately 14.3% of the country’s active workforce, according to the 2020 Medical Demographics in Brazil survey.

The significant participation of health care professionals over age 50 in a survey conducted by this news organization to learn what physicians think about the age limit for practicing their professions is evidence that the subject is a present concern. Of a total of 1,641 participants, 57% were age 60 or older, 17% were between 50 and 59 years, and 12% were between 40 and 49 years. Among all participants, 51% were against these limitations, 17% approved of the idea for all specialties, and 32% believed the restriction was appropriate only for some specialties. Regarding the possibility of older physicians undergoing regular assessments, the opinions were divided: Thirty-one percent thought they should be assessed in all specialties. Furthermore, 31% believed that cognitive abilities should be regularly tested in all specialties, 31% thought this should take place for some specialties, and 38% were against this approach.

Professionals want to know, for example, how (and whether) advanced age can interfere with performance, what are the competences required to practice their activities, and if the criteria vary by specialty. “A psychiatrist doesn’t have to have perfect visual acuity, as required from a dermatologist, but it is important that they have good hearing, for example,” argued Clóvis Constantino, MD, former president of the São Paulo Regional Medical Board (CRM-SP) and former vice president of the Brazilian Federal Medical Board (CFM). “However, a surgeon has to stand for several hours in positions that may be uncomfortable.

It is also not common for professionals to report their own deficits to their institutions. In large part, this is caused by a lack of well-defined policies for dealing with this issue. This news organization sought out several public and private hospitals in Brazil to see if there is any guidance on professional longevity: Most said that there is not. Only the A. C. Camargo Cancer Center reported, through its public relations team, that a committee is discussing the subject but that it is still in the early stages.

Brazilian specialist associations do not offer guidelines or instructions on the various aspects of professional longevity. Dr. Constantino tried to put the subject on the agenda during the years in which he was an administrator with the CFM. “We tried to open up discussions regarding truly elderly physicians, but the subject was not well received. I believe that it is precisely because there is a tradition of physicians working until they are no longer able that this is more difficult in Brazil ... No one exactly knows what to do in this respect.” Dr. Constantino is against the use of age as a criterion for quitting practice.

“Of course, this is a point that has to be considered, but I always defended the need for regular assessment of physicians, regardless of age range. And, although assessments are always welcome, in any profession, I also believe this would not be well received in Brazil.” He endorses an assessment of one’s knowledge and not of physical abilities, which are generally assessed through investigation when needed.

The absence of guidelines increases individual responsibility, as well as vulnerability. “Consciously, physicians will not put patients at risk if they do not have the competence to care for them or to perform a surgical procedure,” said Clystenes Odyr Soares Silva, MD, PhD, adjunct professor of pulmonology of the Federal University of São Paulo (Brazil) School of Medicine (UNIFESP). “Your peers will tell you if you are no longer able,” he added. The problem is that physicians rarely admit to or talk about their colleagues’ deficits, especially if they are in the spotlight because of advanced age. In this situation, the observation and opinion of family members regarding the health care professional’s competences and skills will hold more weight.

In case of health-related physical impairment, such as partial loss of hand movement, for example, “it is expected that this will set off an ethical warning in the person,” said Dr. Constantino. When this warning does not occur naturally, patients or colleagues can report the professional, and this may lead to the opening of an administrative investigation. If the report is found to be true, this investigation is used to suspend physicians who do not have the physical or mental ability to continue practicing medicine.

“If it’s something very serious, the physician’s license can be temporarily suspended while [the physician] is treated by a psychiatrist, with follow-up by the professional board. When discharged, the physician will get his or her [professional] license back and can go back to work,” Dr. Constantino explained. If an expert evaluation is needed, the physician will then be assessed by a forensic psychiatrist. One of the most in-demand forensic psychiatrists in Brazil is Guido Arturo Palomba, MD, 73 years old. “I have assessed some physicians for actions reported to see if they were normal people or not, but never for circumstances related to age,” Dr. Palomba said.

In practice, Brazilian medical entities do not have policies or programs to guide physicians who wish to grow old while they work or those who have started to notice they are not performing as they used to. “We have never lived as long; therefore, the quality of life in old age, as well as the concept of aging, are some of the most relevant questions of our time. These are subjects requiring additional discussion, broadening understanding and awareness in this regard,” observed Mr. Vattimo.

Dr. Constantino and Dr. Silva, who are completely against age-based assessments, believe that recertification of the specialist license every 5 years is the best path to confirming whether the physician is still able to practice. “A knowledge-based test every 5 years to recertify the specialist license has often been a topic of conversation. I think it’s an excellent idea. The person would provide a dossier of all they have done in terms of courses, conferences, and other activities, present it, and receive a score,” said Dr. Silva.

In practice, recertification of the specialist license is a topic of discussion that has been raised for years, and it is an idea that the Brazilian Medical Association (AMB) defends. In conjunction with the CFM, the association is studying a way to best implement this assessment. “It’s important to emphasize that this measure would not be retroactive at first. Instead, it would only be in effect for professionals licensed after the recertification requirement is established,” the AMB pointed out in a note sent to this news organization. Even so, the measure has faced significant resistance from a faction of the profession, and its enactment does not seem to be imminent.

The debate regarding professional longevity is taking place in various countries. In 2021, the American Medical Association Council on Medical Education released a report with a set of guidelines for the screening and assessment of physicians. The document is the product of a committee created in 2015 to study the subject. The AMA recommends that the assessment of elderly physicians be based on evidence and ethical, relevant, fair, equitable, transparent, verifiable, nonexhaustive principles, contemplating support and protecting against legal proceedings. In April of this year, a new AMA document highlighted the same principles.

Also in the United States, one of oldest initiatives created to support physicians in the process of recycling, the University of California San Diego Physician Assessment and Clinical Education Program (PACE), has a section focusing on the extended practice of medicine (Practicing Medicine Longer). For those wanting to learn more about discussions on this subject, there are online presentations on experiences in Quebec and Ontario with assessing aging physicians, neuropsychological perspectives on the aging medical population, and what to expect of healthy aging, among other subjects.

Created in 1996, PACE mostly provides services to physicians who need to address requirements of the state medical boards. Few physicians enroll on their own.

The first part of the program assesses knowledge and skills over approximately 2 days. In the second phase, the physician participates in a series of activities in a corresponding residency program. Depending on the results, the physician may have to go through a remedial program with varying activities to deal with performance deficiencies to clinical experiences at the residency level.

Don’t like needles? Have we got a vaccine for you

Here’s a quick question: How do you turn the most annoying thing ever into something positive?

No, we’re not talking about politicians this time. No, not Elon Musk, either. Infomercials? Guess again. Humidity? Nope, even more annoying than that.

Give up? The most annoying thing ever is mosquitoes. This time, however, NPR reports that mosquitoes have been used to deliver a vaccine for the very disease they’ve been transmitting to their human food sources all these years.

In a recent proof-of-concept trial, investigators used CRISPR technology to genetically modify malaria-causing Plasmodium falciparum sporozoites, which just happen to live in the salivary glands of Anopheles mosquitoes. And since the Plasmodium parasites are already in the mosquitoes, it made sense to use the buzzy little critters as the delivery device for the vaccine.

More sense than a syringe, you ask? Have you ever tried to poke a syringe into the salivary gland of a mosquito? No, we thought not. Well, we can tell you from experience that it’s really, really hard. Never mind how we know. We just do.

The 14 study volunteers – who were paid $4,100 for their participation – were first exposed to hundreds of mosquitoes carrying the altered Plasmodium parasites. Then, to test the vaccine, they were exposed to mosquitoes that had actual, malaria-carrying Plasmodium. Half of the subjects got malaria, so the vaccine was only 50% effective, meaning there’s still work to do.

Meanwhile, the scientists here at LOTMEco are all over this mosquito-delivery business, working on a vaccine to prevent Elon Musk. Plan B involves some sort of really big swatter.
 

Climate change: Sleeping your life away

It’s no secret that climate change is raising the temperature on everything. You may think you’re getting relief when the sun goes down, but in some places it’s still hot. A new survey conducted in central Japan shows how bad it can be and how higher nighttime temperatures can have a serious impact on people’s health.

Public Domain Vectors

That online survey, the Sleep Quality Index for Daily Sleep, enabled the investigators to correlate sleep quality with daily temperature for 1,284 adults in 2011 and 2012 who completed the survey over 10 days.

Not only was there a significant difference in sleep disturbance among younger men (higher) versus older men, but the prevalence of sleep disturbance went up when the daytime temperature was above 24.8° C. They also found that disability-adjusted life-years (DALYs), which measure time lost through premature death and time lived in certain conditions that put one’s health at risk, were 81.8 years for the city of Nagoya (population, 2.2 million) in 2012.

The damage to health from sleep disorders caused by daily temperatures higher than 25° C “is comparable to that of heatstroke and must be addressed,” lead author Tomohiko Ihara of the University of Tokyo said in a written statement.

The researchers hope that this information will help sway legislators to consider the impact of higher nighttime temperatures and that it can be used to provide guidance for better sleep. The solution for now? Sleep with the air conditioner on. Your energy bill might increase, but just think about those DALYs. If using the AC lowers DALYs and increases time lived, then we say it’s worth it.
 

Maybe it would have been a dragon WITH cancer

If you ask a random person on the street to tell you all they know about the country of Wales, they’ll probably mention two things: One, the contorted collection of jumbled-up letters that is the Welsh language (looking at you, Llanfairpwllgwyngyll­gogery­chwyrn­drobwll­llan­tysilio­gogo­goch) and, two, the association with dragons. The Welsh flag even has a dragon on it.

With that in mind, take a guess as to what sort of statue art dealer Simon Wingett wanted to build in the Welsh town of Wrexham. No, not a monument to the second-longest place name in the world. Try again. His dragon would not be some piddly little thing either; he wanted a virtual kaiju overlooking the town, with the whole statue to stand about 60 meters high. That’s taller than the original 1954 Godzilla.

Artistic masterpieces may sell for frankly insane prices, but art dealers themselves are not the wealthiest of individuals, so Mr. Wingett needed money to fund his dragon-based dream. Lucky for him, he also happened to be the manager of a cancer charity – initially set up by Mr. Wingett’s father, who had throat cancer – which nominally aimed to provide equipment and resources to cancer patients in the Wrexham area.

Yes, this is going precisely where you think it’s going. From 2011 to 2018, when the charity closed, Mr. Wingett used the charity’s donations to fund his dragon statue – which never actually got built, by the way – to the tune of over 400,000 pounds. Of course, Mr. Wingett came under scrutiny when people started to notice that his cancer charity hadn’t actually done anything charitable since 2011, and he was recently banned by the Welsh High Court from serving as trustee of any charity for 10 years. Oh no, tragedy and horror! Truly a punishment worse than death itself.

Okay fine, he also has to pay back 117,000 pounds to actual legitimate cancer charities. The astute mathematicians out there may notice that 117,000 is a lot less than 400,000. But it’s just as the old saying goes: One-quarter of crime doesn’t pay. You can keep three-quarters of it, though, that’s completely fine.

Bariatric surgery may raise the risk of developing epilepsy, new research suggests. Analyzing health records, investigators compared almost 17,000 patients who had undergone bariatric surgery with more than 620,000 individuals with obesity who had not undergone the surgery.

During a minimum 3-year follow-up period, the surgery group had a 45% higher risk of developing epilepsy than the nonsurgery group. Moreover, patients who had a stroke after their bariatric surgery were 14 times more likely to develop epilepsy than those who did not have a stroke.

“When considering having bariatric surgery, people should talk to their doctors about the benefits and risks,” senior investigator Jorge Burneo, MD, professor of neurology, biostatistics, and epidemiology and endowed chair in epilepsy at Western University, London, told this news organization.

“While there are many health benefits of weight loss, our findings suggest that epilepsy is a long-term risk of bariatric surgery for weight loss,” Dr. Burneo said.

The findings were published online in Neurology.
 

Unrecognized risk factor?

Bariatric surgery has become more common as global rates of obesity have increased. The surgery has been shown to reduce the risk for serious obesity-related conditions, the researchers note.

However, “in addition to the positive outcomes of bariatric surgery, several long-term neurological complications have also been identified,” they write.

One previous study reported increased epilepsy risk following gastric bypass. Those findings “suggest that bariatric surgery may be an unrecognized epilepsy risk factor; however, this possible association has not been thoroughly explored,” write the investigators.

Dr. Burneo said he conducted the study because he has seen patients with epilepsy in his clinic who were “without risk factors, with normal MRIs, who shared the history of having bariatric surgery before the development of epilepsy.”

The researchers’ primary objective was to “assess whether epilepsy risk is elevated following bariatric surgery for weight loss relative to a nonsurgical cohort of patients who are obese,” he noted.

The study used linked administrative health databases in Ontario, Canada. Patients were accrued from July 1, 2010, to Dec. 31, 2016, and were followed until Dec. 31, 2019. The analysis included 639,472 participants, 2.7% of whom had undergone bariatric surgery.

The “exposed” cohort consisted of all Ontario residents aged 18 years or older who had undergone bariatric surgery during the 6-year period (n = 16,958; 65.1% women; mean age, 47.4 years), while the “unexposed” cohort consisted of patients hospitalized with a diagnosis of obesity who had not undergone bariatric surgery (n = 622,514; 62.8% women; mean age, 47.6 years).

Patients with a history of seizures, epilepsy, epilepsy risk factors, prior brain surgery, psychiatric disorders, or drug or alcohol abuse/dependence were excluded from the analysis.

The researchers collected data on patients’ sociodemographic characteristics at the index date, as well as Charlson Comorbidity Index scores during the 2 years prior to index, and data regarding several specific comorbidities, such as diabetes mellitus, hypertension, sleep apnea, depression/anxiety, and cardiovascular factors.

The exposed and unexposed cohorts were followed for a median period of 5.8 and 5.9 person-years, respectively.
 

‘Unclear’ mechanisms

Before weighting, 0.4% of participants in the exposed cohort (n = 73) developed epilepsy, versus 0.2% of participants in the unexposed cohort (n = 1,260) by the end of the follow-up period.

In the weighted cohorts, there were 50.1 epilepsy diagnoses per 100,000 person-years, versus 34.1 per 100,000 person-years (rate difference, 16 per 100,000 person-years).

The multivariable analysis of the weighted cohort showed the hazard ratio for epilepsy cases that were associated with bariatric surgery was 1.45 (95% confidence interval, 1.35-1.56), after adjusting for sleep apnea and including stroke as a time-varying covariate.

Having a stroke during the follow-up period increased epilepsy 14-fold in the exposed cohort (HR, 14.03; 95% CI, 4.25-46.25).

The investigators note that they were unable to measure obesity status or body mass index throughout the study and that some obesity-related comorbidities “may affect epilepsy risk.”

In addition, Dr. Burneo reported that the study did not investigate potential causes and mechanisms of the association between bariatric surgery and epilepsy risk.

Hypotheses “include potential nutritional deficiencies, receipt of general anesthesia, or other unclear causes,” he said.

“Future research should investigate epilepsy as a potential long-term complication of bariatric surgery, exploring the possible effects of this procedure,” Dr. Burneo added.
 

Risk-benefit discussion

In a comment, Jacqueline French, MD, professor of neurology at NYU Grossman School of Medicine, and director of NYU’s Epilepsy Study Consortium, said she was “not 100% surprised by the findings” because she has seen in her clinical practice “a number of patients who developed epilepsy after bariatric surgery or had a history of bariatric surgery at the time they developed epilepsy.”

On the other hand, she has also seen patients who did not have a history of bariatric surgery and who developed epilepsy.

“I’m unable to tell if there is an association, although I’ve had it at the back of my head as a thought and wondered about it,” said Dr. French, who is also the chief medical and innovation officer at the Epilepsy Foundation. She was not involved with the study.

She noted that possible mechanisms underlying the association are that gastric bypass surgery leads to a “significant alteration” in nutrient absorption. Moreover, “we now know that the microbiome is associated with epilepsy” and that changes occur in the gut microbiome after bariatric surgery, Dr. French said.

There are two take-home messages for practicing clinicians, she added.

“Although the risk [of developing epilepsy] is very low, it should be presented as part of the risks and benefits to patients considering bariatric surgery,” she said.

“It’s equally important to follow up on the potential differences in these patients who go on to develop epilepsy following bariatric surgery,” said Dr. French. “Is there a certain metabolic profile or some nutrient previously absorbed that now is not absorbed that might predispose people to risk?”

This would be “enormously important to know because it might not just pertain to these people but to a whole other cohort of people who develop epilepsy,” Dr. French concluded.

The study was funded by the Ontario Ministry of Health and Ministry of Long-Term Care and by the Jack Cowin Endowed Chair in Epilepsy Research at Western University. Dr. Burneo holds the Jack Cowin Endowed Chair in Epilepsy Research at Western University. The other investigators and Dr. French have reported no relevant financial relationships.

Having a stroke during the follow-up period increased epilepsy 14-fold in the exposed cohort (HR, 14.03; 95% CI, 4.25-46.25).

The investigators note that they were unable to measure obesity status or body mass index throughout the study and that some obesity-related comorbidities “may affect epilepsy risk.”

In addition, Dr. Burneo reported that the study did not investigate potential causes and mechanisms of the association between bariatric surgery and epilepsy risk.

Hypotheses “include potential nutritional deficiencies, receipt of general anesthesia, or other unclear causes,” he said.

“Future research should investigate epilepsy as a potential long-term complication of bariatric surgery, exploring the possible effects of this procedure,” Dr. Burneo added.
 

Risk-benefit discussion

In a comment, Jacqueline French, MD, professor of neurology at NYU Grossman School of Medicine, and director of NYU’s Epilepsy Study Consortium, said she was “not 100% surprised by the findings” because she has seen in her clinical practice “a number of patients who developed epilepsy after bariatric surgery or had a history of bariatric surgery at the time they developed epilepsy.”

On the other hand, she has also seen patients who did not have a history of bariatric surgery and who developed epilepsy.

“I’m unable to tell if there is an association, although I’ve had it at the back of my head as a thought and wondered about it,” said Dr. French, who is also the chief medical and innovation officer at the Epilepsy Foundation. She was not involved with the study.

She noted that possible mechanisms underlying the association are that gastric bypass surgery leads to a “significant alteration” in nutrient absorption. Moreover, “we now know that the microbiome is associated with epilepsy” and that changes occur in the gut microbiome after bariatric surgery, Dr. French said.

There are two take-home messages for practicing clinicians, she added.

“Although the risk [of developing epilepsy] is very low, it should be presented as part of the risks and benefits to patients considering bariatric surgery,” she said.

“It’s equally important to follow up on the potential differences in these patients who go on to develop epilepsy following bariatric surgery,” said Dr. French. “Is there a certain metabolic profile or some nutrient previously absorbed that now is not absorbed that might predispose people to risk?”

This would be “enormously important to know because it might not just pertain to these people but to a whole other cohort of people who develop epilepsy,” Dr. French concluded.

The study was funded by the Ontario Ministry of Health and Ministry of Long-Term Care and by the Jack Cowin Endowed Chair in Epilepsy Research at Western University.

Bariatric surgery may raise the risk of developing epilepsy, new research suggests. Analyzing health records, investigators compared almost 17,000 patients who had undergone bariatric surgery with more than 620,000 individuals with obesity who had not undergone the surgery.

During a minimum 3-year follow-up period, the surgery group had a 45% higher risk of developing epilepsy than the nonsurgery group. Moreover, patients who had a stroke after their bariatric surgery were 14 times more likely to develop epilepsy than those who did not have a stroke.

“When considering having bariatric surgery, people should talk to their doctors about the benefits and risks,” senior investigator Jorge Burneo, MD, professor of neurology, biostatistics, and epidemiology and endowed chair in epilepsy at Western University, London, told this news organization.

“While there are many health benefits of weight loss, our findings suggest that epilepsy is a long-term risk of bariatric surgery for weight loss,” Dr. Burneo said.

The findings were published online in Neurology.
 

Unrecognized risk factor?

Bariatric surgery has become more common as global rates of obesity have increased. The surgery has been shown to reduce the risk for serious obesity-related conditions, the researchers note.

However, “in addition to the positive outcomes of bariatric surgery, several long-term neurological complications have also been identified,” they write.

One previous study reported increased epilepsy risk following gastric bypass. Those findings “suggest that bariatric surgery may be an unrecognized epilepsy risk factor; however, this possible association has not been thoroughly explored,” write the investigators.

Dr. Burneo said he conducted the study because he has seen patients with epilepsy in his clinic who were “without risk factors, with normal MRIs, who shared the history of having bariatric surgery before the development of epilepsy.”

The researchers’ primary objective was to “assess whether epilepsy risk is elevated following bariatric surgery for weight loss relative to a nonsurgical cohort of patients who are obese,” he noted.

The study used linked administrative health databases in Ontario, Canada. Patients were accrued from July 1, 2010, to Dec. 31, 2016, and were followed until Dec. 31, 2019. The analysis included 639,472 participants, 2.7% of whom had undergone bariatric surgery.

The “exposed” cohort consisted of all Ontario residents aged 18 years or older who had undergone bariatric surgery during the 6-year period (n = 16,958; 65.1% women; mean age, 47.4 years), while the “unexposed” cohort consisted of patients hospitalized with a diagnosis of obesity who had not undergone bariatric surgery (n = 622,514; 62.8% women; mean age, 47.6 years).

Patients with a history of seizures, epilepsy, epilepsy risk factors, prior brain surgery, psychiatric disorders, or drug or alcohol abuse/dependence were excluded from the analysis.

The researchers collected data on patients’ sociodemographic characteristics at the index date, as well as Charlson Comorbidity Index scores during the 2 years prior to index, and data regarding several specific comorbidities, such as diabetes mellitus, hypertension, sleep apnea, depression/anxiety, and cardiovascular factors.

The exposed and unexposed cohorts were followed for a median period of 5.8 and 5.9 person-years, respectively.
 

‘Unclear’ mechanisms

Before weighting, 0.4% of participants in the exposed cohort (n = 73) developed epilepsy, versus 0.2% of participants in the unexposed cohort (n = 1,260) by the end of the follow-up period.

In the weighted cohorts, there were 50.1 epilepsy diagnoses per 100,000 person-years, versus 34.1 per 100,000 person-years (rate difference, 16 per 100,000 person-years).

The multivariable analysis of the weighted cohort showed the hazard ratio for epilepsy cases that were associated with bariatric surgery was 1.45 (95% confidence interval, 1.35-1.56), after adjusting for sleep apnea and including stroke as a time-varying covariate.

Having a stroke during the follow-up period increased epilepsy 14-fold in the exposed cohort (HR, 14.03; 95% CI, 4.25-46.25).

The investigators note that they were unable to measure obesity status or body mass index throughout the study and that some obesity-related comorbidities “may affect epilepsy risk.”

In addition, Dr. Burneo reported that the study did not investigate potential causes and mechanisms of the association between bariatric surgery and epilepsy risk.
