Since the COVID-19 pandemic started more than 3 years ago, the longer-lasting effects of SARS-CoV-2 infection have continued to reveal themselves. Approximately 28% of Americans report having ever experienced post-COVID conditions, such as brain fog, postexertional malaise, and joint pain, and 11% say they are still experiencing these long-term effects. Now, new research is showing that people who have had COVID are more likely to newly develop an autoimmune disease. Exactly why this is happening is less clear, experts say.

Two preprint studies and one study published in a peer-reviewed journal provide strong evidence that patients who have been infected with SARS-CoV-2 are at elevated risk of developing an autoimmune disease. The studies retrospectively reviewed medical records from three countries and compared the incidence of new-onset autoimmune disease among patients who had polymerase chain reaction–confirmed COVID-19 and those who had never been diagnosed with the virus.

A study analyzing the health records of 3.8 million U.S. patients – more than 888,460 with confirmed COVID-19 – found that the COVID-19 group was two to three times as likely to develop various autoimmune diseases, such as rheumatoid arthritis, systemic lupus erythematosus, and systemic sclerosis. A U.K. preprint study that included more than 458,000 people with confirmed COVID found that those who had previously been infected with SARS-CoV-2 were 22% more likely to develop an autoimmune disease compared with the control group. In this cohort, the diseases most strongly associated with COVID-19 were type 1 diabetes, inflammatory bowel disease, and psoriasis. A preprint study from German researchers found that COVID-19 patients were almost 43% more likely to develop an autoimmune disease, compared with those who had never been infected. COVID-19 was most strongly linked to vasculitis.
 

These large studies are telling us, “Yes, this link is there, so we have to accept it,” Sonia Sharma, PhD, of the Center for Autoimmunity and Inflammation at the La Jolla (Calif.) Institute for Immunology, told this news organization. But this is not the first time that autoimmune diseases have been linked to previous infections.

Researchers have known for decades that Epstein-Barr virus infection is linked to several autoimmune diseases, including systemic lupus erythematosus, multiple sclerosis, and rheumatoid arthritis. More recent research suggests the virus may activate certain genes associated with these immune disorders. Hepatitis C virus can induce cryoglobulinemia, and infection with cytomegalovirus has been implicated in several autoimmune diseases. Bacterial infections have also been linked to autoimmunity, such as group A streptococcus and rheumatic fever, as well as salmonella and reactive arthritis, to name only a few.

“In a way, this isn’t necessarily a new concept to physicians, particularly rheumatologists,” said Jeffrey A. Sparks, MD, a rheumatologist at Brigham and Women’s Hospital in Boston. “There’s a fine line between appropriately clearing an infection and the body overreacting and setting off a cascade where the immune system is chronically overactive that can manifest as an autoimmune disease,” he told this news organization.

A dysregulated response to infection

It takes the immune system a week or two to develop antigen-specific antibodies to a new pathogen. But for patients with serious infections – in this instance, COVID-19 – that’s time they don’t have. Therefore, the immune system has an alternative pathway, called extrafollicular activation, that creates fast-acting antibodies, explained Matthew Woodruff, PhD, an instructor of immunology and rheumatology at Emory University, Atlanta.

The trade-off is that these antibodies are not as specific and can target the body’s own tissues. This dysregulation of antibody selection is generally short lived and fades when more targeted antibodies are produced and take over, but in some cases, this process can lead to high levels of self-targeting antibodies that can harm the body’s organs and tissues. Research also suggests that for patients who experience long COVID, the same autoantibodies that drive the initial immune response are detectable in the body months after infection, though it is not known whether these lingering immune cells cause these longer-lasting symptoms.

“If you have a virus that causes hyperinflammation plus organ damage, that is a recipe for disaster,” Dr. Sharma said. “It’s a recipe for autoantibodies and autoreactive T cells that down the road can attack the body’s own tissues, especially in people whose immune system is trained in such a way to cause self-reactivity,” she added.

This hyperinflammation can result in rare but serious complications, such as multisystem inflammatory syndrome in children and adults, which can occur 2-6 weeks after SARS-CoV-2 infection. But even in these patients with severe illness, organ-specific complications tend to resolve in 6 months with “no significant sequelae 1 year after diagnosis,” according to the Centers for Disease Control and Prevention. And while long COVID can last for a year or longer, data suggest that symptoms do eventually resolve for most people. What is not clear is why acute autoimmunity triggered by COVID-19 can become a chronic condition in certain patients.
 

Predisposition to autoimmunity

P. J. Utz, MD, PhD, professor of immunology and rheumatology at Stanford (Calif.) University, said that people who develop autoimmune disease after SARS-CoV-2 infection may have already been predisposed toward autoimmunity. Especially for autoimmune diseases such as type 1 diabetes and lupus, autoantibodies can appear and circulate in the body for more than a decade in some people before they present with any clinical symptoms. “Their immune system is primed such that if they get infected with something – or they have some other environmental trigger that maybe we don’t know about yet – that is enough to then push them over the edge so that they get full-blown autoimmunity,” he said. What is not known is whether these patients’ conditions would have advanced to true clinical disease had they not been infected, he said.

He also noted that the presence of autoantibodies does not necessarily mean someone has autoimmune disease; healthy people can also have autoantibodies, and everyone develops them with age. “My advice would be, ‘Don’t lose sleep over this,’ “ he said.

Dr. Sparks agreed that while these retrospective studies did show an elevated risk of autoimmune disease after COVID-19, that risk appears to be relatively small. “As a practicing rheumatologist, we aren’t seeing a stampede of patients with new-onset rheumatic diseases,” he said. “It’s not like we’re overwhelmed with autoimmune patients, even though almost everyone’s had COVID. So, if there is a risk, it’s very modest.”

Mickey Research Scholar Fund, and the Llura Gund Award for Rheumatoid Arthritis Research and Care. Dr. Utz receives research funding from Pfizer.

The recent approval of the first oral fecal-derived microbiota therapy to prevent the recurrence of Clostridioides difficile (C. diff) infection in patients was welcome news for physicians who’ve struggled under the weight of having too few treatment options for the prevention of C. diff recurrence.

The product, developed by Massachusetts-based Seres Therepeutics and marketed as Vowst, was approved by the U.S. Food and Drug Administration on April 26. It is approved for use in adults who have already been treated with antibiotics for a recurrent infection with C. diff bacteria.

This is the first oral treatment for the prevention of C. diff recurrence and is designed to be delivered in four capsules taken daily for 3 days.

Gastroenterologist Phillip I. Tarr, MD, division chief of gastroenterology at Washington University, St. Louis, and chair of the American Gastroenterological Association Center for Gut Microbiome Research and Education, said that prevention of recurrent C. diff infection “remains challenging,” and that Vowst “provides the first FDA-approved, orally administered microbiome therapeutic with which to achieve this goal. This advance also makes us optimistic we might soon be able to prevent other disorders by managing gut microbial communities.”

Vowst is the second therapy derived from human stool to be approved for the indication in less than 6 months. In December, the FDA approved Rebyota (Ferring), a rectally delivered treatment that also uses microbes from donor feces. Both products were given priority review, orphan drug, and breakthrough therapy designations by the agency.

C. diff infection can be aggravated by an alteration of normal gut flora associated with antibiotics treatment, leading to cycles of repeated infections. Infection can produce diarrhea, abdominal pain, fever, and severe morbidity. In the United States, an estimated 15,000 to 30,000 deaths per year are linked to C. diff. Risk factors for recurrent infection include being 65 or older, hospitalization, being in a nursing home, a weakened immune system, and previous infection with C. diff.

Therapies transplanting fecal microbiota from donors have been used since the 1950s as treatments for recurrent C. diff infection, and in the past decade, as stool banks recruiting screened donors have made fecal microbiota transplants, or FMT, standard of care. However, only in recent years have fecal-derived therapies become subject to standardized safety and efficacy testing.

Both the current FDA-approved products, Rebyota and Vowst, were shown in randomized controlled trials to reduce recurrence of C. diff infection, compared with placebo. In a phase 3 clinical trial of Rebyota (n = 262) in antibiotic-treated patients, one rectally administered dose reduced recurrence of C. diff infection by 70.6% at 8 weeks, compared with 57.5% for placebo. A phase 3 study of Vowst (n = 281) showed recurrence in treated subjects to be 12.4% at 8 weeks, compared with nearly 40% of those receiving placebo (relative risk, 0.32; 95% confidence interval, 0.18-0.58; P less than .001).

Despite screening protocols that have become increasingly homogenized and rigorous, FMT is associated with the risk of introducing pathogens. Vowst is manufactured with purified bacterial spores derived from donor feces, not whole stool. Nonetheless, FDA noted in its statement that Vowst could still potentially introduce infectious agents or allergens.
 

Antibiotics are still first-line treatment

In an interview, Jessica Allegretti, MD, MPH, AGAF, medical director of the Crohn’s and Colitis Center at Brigham & Women’s Hospital, Boston, said that having two FDA-approved therapies with different means of administration “is great for the field and great for patients. These are both meant to be used after a course of antibiotics, so antibiotics are still the mainstay of treatment for C. diff and recurrent C. diff, but we now have more options to prevent recurrence.”

The convenience of an oral therapy that can be taken at home is “very attractive,” Dr. Allegretti added, noting that there will also be patients “who either don’t want to or can’t take capsules, for whom a rectal administration [in a health care setting] may be preferred.”

Dr. Allegretti, who has used FMT to treat recurrent C. difficile for more than a decade, said that she expected traditional FMT using screened donor stool to remain available even as the new products are adopted by clinicians. FMT centers like OpenBiome “will continue to provide access for patients who either don’t have the ability to get the FDA-approved products because of insurance coverage, or for financial reasons, or maybe neither of the new products is appropriate for them,” she said. “I do think there will always be a need for the traditional option. The more options that we have available the better.”

TD Cowen analyst Joseph Thome told Reuters that the drug could be priced close to $20,000 per course, expecting peak sales of $750 million in the U.S. in 2033.

Dr. Allegretti disclosed consulting work for Seres Therapeutics, Ferring, and other manufacturers. She is a member of OpenBiome’s clinical advisory board.

The convenience of an oral therapy that can be taken at home is “very attractive,” Dr. Allegretti added, noting that there will also be patients “who either don’t want to or can’t take capsules, for whom a rectal administration [in a health care setting] may be preferred.”

Dr. Allegretti, who has used FMT to treat recurrent C. difficile for more than a decade, said that she expected traditional FMT using screened donor stool to remain available even as the new products are adopted by clinicians. FMT centers like OpenBiome “will continue to provide access for patients who either don’t have the ability to get the FDA-approved products because of insurance coverage, or for financial reasons, or maybe neither of the new products is appropriate for them,” she said. “I do think there will always be a need for the traditional option. The more options that we have available the better.”

TD Cowen analyst Joseph Thome told Reuters that the drug could be priced close to $20,000 per course, expecting peak sales of $750 million in the U.S. in 2033.

Dr. Allegretti disclosed consulting work for Seres Therapeutics, Ferring, and other manufacturers. She is a member of OpenBiome’s clinical advisory board.

A new study shows that people with long COVID respond differently to COVID vaccines and that the condition may be caused by a dysfunction of the immune system – possibly explaining why some people experience symptoms for months while others recover and resume normal lives. 

The study compared people who already had long COVID with people who had recovered from the virus. Both groups had not yet been vaccinated prior to the study. When researchers analyzed blood samples after people received an initial vaccine dose, they found that people with long COVID and people who had already recovered from the virus had similar immune responses at first. But after 8 weeks, the long-COVID group’s immune response remained elevated, while the other group’s response had declined.

The long-COVID group also showed an extra immune response that tried to fight the virus in a secondary way that researchers didn’t expect. Both groups showed an initial increase in their blood of antibodies that primarily target what’s known as the “spike” protein of the coronavirus, which allows the virus to invade healthy cells. But the long-COVID group also showed a prolonged increased immune response that tried to fight the part of the virus related to how it replicates.

“Theoretically, the production of these antibodies could mean that people are more protected from infection,” said researcher Catherine Le, MD, in a statement. “We also need to investigate if the elevated immune response corresponds with severity or number of long–COVID-19 symptoms.”

Dr. Le is codirector of the COVID-19 Recovery Program at Cedars-Sinai Medical Center in Los Angeles, where the study was conducted.

Study participants agreed in September 2020 to participate in long-term COVID research at Cedars-Sinai. The new analysis was published earlier this year in BMC Infectious Diseases and included 245 people who had long COVID and 86 health care workers who had recovered from COVID but did not have long-term symptoms. 

For the study, long COVID was defined as having symptoms that lasted more than 12 weeks. Common long-COVID symptoms are fatigue, shortness of breath, and brain dysfunction such as confusion and forgetfulness.

The authors said it’s unclear why the two groups had different immune responses and also noted that their study was limited by a small sample size. Their research of blood samples is ongoing, with the goals of identifying a way to diagnose long COVID with a laboratory test and of better understanding what causes the condition.

Taking a swing against arthritis

Osteoarthritis is a tough disease to manage. Exercise helps ease the stiffness and pain of the joints, but at the same time, the disease makes it difficult to do that beneficial exercise. Even a relatively simple activity like jogging can hurt more than it helps. If only there were a low-impact exercise that was incredibly popular among the generally older population who are likely to have arthritis.

We love a good golf study here at LOTME, and a group of Australian and U.K. researchers have provided. Osteoarthritis affects 2 million people in the land down under, making it the most common source of disability there. In that population, only 64% reported their physical health to be good, very good, or excellent. Among the 459 golfers with OA that the study authors surveyed, however, the percentage reporting good health rose to more than 90%.

A similar story emerged when they looked at mental health. Nearly a quarter of nongolfers with OA reported high or very high levels of psychological distress, compared with just 8% of golfers. This pattern of improved physical and mental health remained when the researchers looked at the general, non-OA population.

This isn’t the first time golf’s been connected with improved health, and previous studies have shown golf to reduce the risks of cardiovascular disease, diabetes, and obesity, among other things. Just walking one 18-hole round significantly exceeds the CDC’s recommended 150 minutes of physical activity per week. Go out multiple times a week – leaving the cart and beer at home, American golfers – and you’ll be fit for a lifetime.

The golfers on our staff, however, are still waiting for those mental health benefits to kick in. Because when we’re adding up our scorecard after that string of four double bogeys to end the round, we’re most definitely thinking: “Yes, this sport is reducing my psychological distress. I am having fun right now.”
 

Battle of the sexes’ intestines

There are, we’re sure you’ve noticed, some differences between males and females. Females, for one thing, have longer small intestines than males. Everybody knows that, right? You didn’t know? Really? … Really?

Afif Ramdhasuma/Unsplash

Well, then, we’re guessing you haven’t read “Hidden diversity: Comparative functional morphology of humans and other species” by Erin A. McKenney, PhD, of North Carolina State University, Raleigh, and associates, which just appeared in PeerJ. We couldn’t put it down, even in the shower – a real page-turner/scroller. (It’s a great way to clean a phone, for those who also like to scroll, text, or talk on the toilet.)

The researchers got out their rulers, calipers, and string and took many measurements of the digestive systems of 45 human cadavers (21 female and 24 male), which were compared with data from 10 rats, 10 pigs, and 10 bullfrogs, which had been collected (the measurements, not the animals) by undergraduate students enrolled in a comparative anatomy laboratory course at the university.

There was little intestinal-length variation among the four-legged subjects, but when it comes to humans, females have “consistently and significantly longer small intestines than males,” the investigators noted.

The women’s small intestines, almost 14 feet long on average, were about a foot longer than the men’s, which suggests that women are better able to extract nutrients from food and “supports the canalization hypothesis, which posits that women are better able to survive during periods of stress,” coauthor Amanda Hale said in a written statement from the school. The way to a man’s heart may be through his stomach, but the way to a woman’s heart is through her duodenum, it seems.

Fascinating stuff, to be sure, but the thing that really caught our eye in the PeerJ article was the authors’ suggestion “that organs behave independently of one another, both within and across species.” Organs behaving independently? A somewhat ominous concept, no doubt, but it does explain a lot of the sounds we hear coming from our guts, which can get pretty frightening, especially on chili night.
 

Dog walking is dangerous business

Yes, you did read that right. A lot of strange things can send you to the emergency department. Go ahead and add dog walking onto that list.

Investigators from Johns Hopkins University estimate that over 422,000 adults presented to U.S. emergency departments with leash-dependent dog walking-related injuries between 2001 and 2020.

freestocks/Unsplash

With almost 53% of U.S. households owning at least one dog in 2021-2022 in the wake of the COVID pet boom, this kind of occurrence is becoming more common than you think. The annual number of dog-walking injuries more than quadrupled from 7,300 to 32,000 over the course of the study, and the researchers link that spike to the promotion of dog walking for fitness, along with the boost of ownership itself.

The most common injuries listed in the National Electronic Injury Surveillance System database were finger fracture, traumatic brain injury, and shoulder sprain or strain. These mostly involved falls from being pulled, tripped, or tangled up in the leash while walking. For those aged 65 years and older, traumatic brain injury and hip fracture were the most common.

Women were 50% more likely to sustain a fracture than were men, and dog owners aged 65 and older were three times as likely to fall, twice as likely to get a fracture, and 60% more likely to have brain injury than were younger people. Now, that’s not to say younger people don’t also get hurt. After all, dogs aren’t ageists. The researchers have that data but it’s coming out later.

Meanwhile, the pitfalls involved with just trying to get our daily steps in while letting Muffin do her business have us on the lookout for random squirrels.

Abdul Moiz Hafiz, MD, was flabbergasted when he received a phone call from his institution’s credentialing office telling him that he was not certified for interventional cardiology – even though he had passed that exam in 2016.

Dr. Hafiz, who directs the Advanced Structural Heart Disease Program at Southern Illinois University, phoned the American Board of Internal Medicine (ABIM), where he learned that to restore his credentials, he would need to pay $1,225 in maintenance of certification (MOC) fees.

Like Dr. Hafiz, many physicians have been dismayed to learn that the ABIM is now listing as “not certified” physicians who have passed board exams but have not paid annual MOC fees of $220 per year for the first certificate and $120 for each additional certificate.

Even doctors who are participating in mandatory continuing education outside the ABIM’s auspices are finding themselves listed as “not certified.” Some physicians learned of the policy change only after applying for hospital privileges or for jobs that require ABIM certification.

Now that increasing numbers of physicians are employed by hospitals and health care organizations that require ABIM certification, many doctors have no option but to pony up the fees if they want to continue to practice medicine.

“We have no say in the matter,” said Dr. Hafiz, “and there’s no appeal process.”

The change affects nearly 330,000 physicians. Responses to the policy on Twitter included accusations of extortion and denunciations of the ABIM’s “money grab policies.”

Sunil Rao, MD, director of interventional cardiology at NYU Langone Health and president of the Society for Cardiovascular Angiography and Interventions (SCAI), has heard from many SCAI members who had experiences similar to Dr. Hafiz’s. While Dr. Rao describes some of the Twitter outrage as “emotional,” he does acknowledge that the ABIM’s moves appear to be financially motivated.

“The issue here was that as soon as they paid the fee, all of a sudden, ABIM flipped the switch and said they were certified,” he said. “It certainly sounds like a purely financial kind of structure.”

Richard Baron, MD, president and CEO of the ABIM, said doctors are misunderstanding the policy change.

“No doctor loses certification solely for failure to pay fees,” Dr. Baron told this news organization. “What caused them to be reported as not certified was that we didn’t have evidence that they had met program requirements. They could say, ‘But I did meet program requirements, you just didn’t know it.’ To which our answer would be, for us to know it, we have to process them. And our policy is that we don’t process them unless you are current on your fees.”

This is not the first time ABIM policies have alienated physicians.

Last year, the ABIM raised its MOC fees from $165 to $220. That also prompted a wave of outrage. Other grievances go further back. At one time, being board certified was a lifetime credential. However, in 1990 the ABIM made periodic recertification mandatory.

The process, which came to be known as “maintenance of certification,” had to be completed every 10 years, and fees were charged for each certification. At that point, said Dr. Baron, the relationship between the ABIM and physicians changed from a one-time interaction to a career-long relationship. He advises doctors to check in periodically on their portal page at the ABIM or download the app so they will always know their status.

Many physicians would prefer not to be bound to a lifetime relationship with the ABIM. There is an alternative licensing board, the National Board of Physicians and Surgeons (NBPAS), but it is accepted by only a limited number of hospitals.

“Until the NBPAS gains wide recognition,” said Dr. Hafiz, “the ABIM is going to continue to have basically a monopoly over the market.”

The value of MOC itself has been called into question. “There are no direct data supporting the value of the MOC process in either improving care, making patient care safer, or making patient care higher quality,” said Dr. Rao. This feeds frustration in a clinical community already dealing with onerous training requirements and expensive board certification exams and adds to the perception that it is a purely financial transaction, he said. (Studies examining whether the MOC system improves patient care have shown mixed results.)

The true value of the ABIM to physicians, Dr. Baron contends, is that the organization is an independent third party that differentiates those doctors from people who don’t have their skills, training, and expertise. “In these days, where anyone can be an ‘expert’ on the Internet, that’s more valuable than ever before,” he said.

The true value of the ABIM to physicians, Dr. Baron contends, is that the organization is an independent third party that differentiates those doctors from people who don’t have their skills, training, and expertise. “In these days, where anyone can be an ‘expert’ on the Internet, that’s more valuable than ever before,” he said.

Abdul Moiz Hafiz, MD, was flabbergasted when he received a phone call from his institution’s credentialing office telling him that he was not certified for interventional cardiology – even though he had passed that exam in 2016.

Dr. Hafiz, who directs the Advanced Structural Heart Disease Program at Southern Illinois University, phoned the American Board of Internal Medicine (ABIM), where he learned that to restore his credentials, he would need to pay $1,225 in maintenance of certification (MOC) fees.

Like Dr. Hafiz, many physicians have been dismayed to learn that the ABIM is now listing as “not certified” physicians who have passed board exams but have not paid annual MOC fees of $220 per year for the first certificate and $120 for each additional certificate.

Even doctors who are participating in mandatory continuing education outside the ABIM’s auspices are finding themselves listed as “not certified.” Some physicians learned of the policy change only after applying for hospital privileges or for jobs that require ABIM certification.

Now that increasing numbers of physicians are employed by hospitals and health care organizations that require ABIM certification, many doctors have no option but to pony up the fees if they want to continue to practice medicine.

“We have no say in the matter,” said Dr. Hafiz, “and there’s no appeal process.”

The change affects nearly 330,000 physicians. Responses to the policy on Twitter included accusations of extortion and denunciations of the ABIM’s “money grab policies.”

Sunil Rao, MD, director of interventional cardiology at NYU Langone Health and president of the Society for Cardiovascular Angiography and Interventions (SCAI), has heard from many SCAI members who had experiences similar to Dr. Hafiz’s. While Dr. Rao describes some of the Twitter outrage as “emotional,” he does acknowledge that the ABIM’s moves appear to be financially motivated.

“The issue here was that as soon as they paid the fee, all of a sudden, ABIM flipped the switch and said they were certified,” he said. “It certainly sounds like a purely financial kind of structure.”

Richard Baron, MD, president and CEO of the ABIM, said doctors are misunderstanding the policy change.

“No doctor loses certification solely for failure to pay fees,” Dr. Baron told this news organization. “What caused them to be reported as not certified was that we didn’t have evidence that they had met program requirements. They could say, ‘But I did meet program requirements, you just didn’t know it.’ To which our answer would be, for us to know it, we have to process them. And our policy is that we don’t process them unless you are current on your fees.”

This is not the first time ABIM policies have alienated physicians.

Last year, the ABIM raised its MOC fees from $165 to $220. That also prompted a wave of outrage. Other grievances go further back. At one time, being board certified was a lifetime credential. However, in 1990 the ABIM made periodic recertification mandatory.

The process, which came to be known as “maintenance of certification,” had to be completed every 10 years, and fees were charged for each certification. At that point, said Dr. Baron, the relationship between the ABIM and physicians changed from a one-time interaction to a career-long relationship. He advises doctors to check in periodically on their portal page at the ABIM or download the app so they will always know their status.

Many physicians would prefer not to be bound to a lifetime relationship with the ABIM. There is an alternative licensing board, the National Board of Physicians and Surgeons (NBPAS), but it is accepted by only a limited number of hospitals.

“Until the NBPAS gains wide recognition,” said Dr. Hafiz, “the ABIM is going to continue to have basically a monopoly over the market.”

The value of MOC itself has been called into question. “There are no direct data supporting the value of the MOC process in either improving care, making patient care safer, or making patient care higher quality,” said Dr. Rao. This feeds frustration in a clinical community already dealing with onerous training requirements and expensive board certification exams and adds to the perception that it is a purely financial transaction, he said. (Studies examining whether the MOC system improves patient care have shown mixed results.)

The true value of the ABIM to physicians, Dr. Baron contends, is that the organization is an independent third party that differentiates those doctors from people who don’t have their skills, training, and expertise. “In these days, where anyone can be an ‘expert’ on the Internet, that’s more valuable than ever before,” he said.

Scent-detecting dogs have long been used to sniff out medical conditions ranging from low blood sugar and cancer to malaria, impending seizures, and migraines – not to mention explosives and narcotics.

Recently, the sensitivity of the canine nose has been tested as a strategy for screening for SARS-CoV-2 infection in schoolchildren showing no outward symptoms of the virus. A pilot study led by Carol A. Glaser, DVM, MD, of the California Department of Public Health in Richmond, found that trained dogs had an accuracy of more than 95% for detecting the odor of volatile organic compounds, or VOCs, produced by COVID-infected individuals.

The authors believe that odor-based diagnosis with dogs could eventually provide a rapid, inexpensive, and noninvasive way to screen large groups for COVID-19 without the need for antigen testing.

“This is a new program with research ongoing, so it would be premature to consider it from a consumer’s perspective,” Dr. Glaser said in an interview. “However, the data look promising and we are hopeful we can continue to pilot various programs in various settings to see where, and if, dogs can be used for biomedical detection.”
 

In the lab and in the field

In a study published online in JAMA Pediatrics, Dr. Glaser’s group found that after 2 months’ training on COVID-19 scent samples in the laboratory, the dogs detected the presence of the virus more than 95% of the time. Antigen tests were used as a comparative reference.

In medical terms, the dogs achieved a greater than 95% accuracy on two important measures of effectiveness: sensitivity – a test’s ability to correctly detect the positive presence of disease – and specificity – the ability of a test to accurately rule out the presence of disease and identify as negative an uninfected person.

Next, the researchers piloted field tests in 50 visits at 27 schools from April 1 to May 25, 2022, to compare dogs’ detection ability with that of standard laboratory antigen testing. Participants in the completely voluntary screening numbered 1,558 and ranged in age from 9 to 17 years. Of these, 56% were girls and 89% were students. Almost 70% were screened at least twice.

Overall, the field test compared 3,897 paired antigen-vs.-dog screenings. The dogs accurately signaled the presence of 85 infections and ruled out 3,411 infections, for an overall accuracy of 90%. In 383 cases, however, they inaccurately signaled the presence of infection (false positives) and missed 18 actual infections (false negatives). That translated to a sensitivity in the field of 83%, considerably lower than that of their lab performance.

Direct screening of individuals with dogs outside of the lab involved circumstantial factors that likely contributed to decreased sensitivity and specificity, the authors acknowledged. These included such distractions as noise and the presence of excitable young children as well environmental conditions such as wind and other odors. What about dog phobia and dog hair allergy? “Dog screening takes only a few seconds per student and the dogs do not generally touch the participant as they run a line and sniff at ankles,” Dr. Glaser explained.

As for allergies, the rapid, ankle-level screening occurred in outdoor settings. “The chance of allergies is very low. This would be similar to someone who is out walking on the sidewalk and walks by a dog,” Dr. Glaser said.

Last year, a British trial of almost 4,000 adults tested six dogs trained to detect differences in VOCs between COVID-infected and uninfected individuals. Given samples from both groups, the dogs were able to distinguish between infected and uninfected samples with a sensitivity for detecting the virus ranging from 82% to 94% and a specificity for ruling it out of 76% to 92%. And they were able to smell the VOCs even when the viral load was low. The study also tested organic sensors, which proved even more accurate than the canines.

According to lead author James G. Logan, PhD, a disease control expert at the London School of Hygiene & Tropical Medicine in London, “Odour-based diagnostics using dogs and/or sensors may prove a rapid and effective tool for screening large numbers of people. Mathematical modelling suggests that dog screening plus a confirmatory PCR test could detect up to 89% of SARS-CoV-2 infections, averting up to 2.2 times as much transmission compared to isolation of symptomatic individuals only.”

Funding was provided by the Centers for Disease Control and Prevention Foundation (CDCF) to Early Alert Canines for the purchase and care of the dogs and the support of the handlers and trainers. The CDCF had no other role in the study. Coauthor Carol A. Edwards of Early Alert Canines reported receiving grants from the CDCF.

Doctors’ groups are lining up to support new federal legislation to permanently tie Medicare physician payment updates to inflation.

Introduced by four physician U.S. House representatives, HR 2474 would link Medicare fee schedule updates to the Medicare Economic Index, a measure of inflation related to physicians’ practice costs and wages.

That’s a long-sought goal of the American Medical Association, which is leading 120 state medical societies and medical specialty groups in championing the bill.

The legislation is essential to enabling physician practices to better absorb payment distributions triggered by budget neutrality rules, performance adjustments, and periods of high inflation, the groups wrote in a joint letter sent to the bill’s sponsors. The sponsors say they hope the legislation will improve access to care, as low reimbursements cause some physicians to limit their number of Medicare patients.

Physicians groups for years have urged federal lawmakers to scrap short-term fixes staving off Medicare pay cuts in favor of permanent reforms. Unlike nearly all other Medicare clinicians including hospitals, physicians’ Medicare payment updates aren’t currently tied to inflation.

Adjusted for inflation, Medicare payments to physicians have declined 26% between 2001 and 2023, including a 2% payment reduction in 2023, according to the AMA. Small and rural physician practices have been disproportionately affected by these reductions, as have doctors treating low-income or uninsured patients, the AMA said.

Last month, an influential federal advisory panel recommended permanently tying Medicare physician pay increases to inflation. Clinicians’ cost of providing services, measured by the Medicare Economic Index, rose by 2.6% in 2021 and are estimated to have risen 4.7% in 2022, significantly more than in recent years, the Medicare Payment Advisory Commission said.

A new federal research project aims to answer lingering questions about long COVID using mobile monitoring devices to help track the condition.

The federally funded RECOVER Initiative expects to give out 10,000 sensors to people with long COVID to collect data in real time.

Terry Rudd/MDedge News

The hope is that researchers will be able to provide doctors and patients with a wealth of information to address gaps in knowledge about long COVID.

The project takes advantage of the approach other researchers have used to track patients’ health data on heart rate, exercise, and more using mobile monitoring devices such as Fitbits, smartwatches, and other remote sensors. 

Researchers believe the initiative could be particularly useful for people with long COVID – whose symptoms come and go. They can use a wristband sensor to passively collect data in real time.

For a condition defined by its symptoms, that kind of data promises to be useful, experts said. 

But not everyone has room in their budget for a smartwatch or a fitness tracker. Until recently, most clinical trials were BYOD: Bring your own device. At a time when researchers are trying to make sure that clinical trials reflect the diversity of the population, that leaves a lot of people out.

So, researchers are starting to supply subjects with their own monitors. The RECOVER Initiative expects to give out 10,000 sensors to people who are eligible based on race/ethnicity, income, and other demographic factors (rural residents for example). After 2 months, all people in the RECOVER study over the age of 13 will be eligible for the sensors.

The federal program builds on earlier research at places like The Scripps Institute, a center of research into remote monitoring. The institute supplied 7,000 monitors to people in an arm of the All of Us study, a 5-year-old multisite cohort that aims to collect medical information from 1 million people. 

The devices went to people who have been historically underrepresented in biomedical research, said Scripps researchers, who plan to give out more this year. 

In March of 2023, Scripps researchers published a study on the tracking data that found a significant post-COVID-19 drop in physical activity. But the data are incomplete because many people can’t always afford these devices. Most of the people in the study were “White, young, and active,” they wrote.

Researchers at an All of Us site at Vanderbilt University, which also used a BYOD approach, realized that they produced biased results. They reported their findings at the Pacific Symposium on Biocomputing in January.

“[The] majority of participants who provided Fitbit data reported being White and employed for wages,” they said. “However, these data represent participants who had their own Fitbit devices and consented to share EHR [electronic health record] data.”

Their solution: The program has begun providing Fitbit devices to all study participants who do not own one or cannot afford one. 

Now, the web page for the All of Us study asks visitors to “Learn about the All of Us WEAR study. You could get a Fitbit at no cost! … As a part of the WEAR Study, you could receive a new Fitbit to wear at no cost to you. All of Us will be able to get the data the Fitbit collects. This data may help us understand how behavior impacts health.”

Jennifer Radin, PhD, an epidemiologist at Scripps Research Translational Institute, is heading up the DETECT study, which is a remote monitoring research project that has enrolled over 40,000 people who have their own sensors – be it a smartwatch or Fitbit. She was looking at remote monitoring for disease before COVID emerged.

Dr. Radin said she began researching remote sensing after working in public health and dealing with outdated data collection systems. 

“They typically rely on case reports that are recorded by pen and paper and faxed or mailed in,” she said. “Then, they have to be entered into a database. “

In addition to offering objective data on a subject’s physical response to the infection, she said, the data collection can be long-term and continuous. 

DETECT collects data on resting heart rate, which is unique to every person, and activity levels. Both measures are meaningful for those with long COVID. Her research found differences in sleep, heart rate, and activity between those with COVID and those without.

Joseph Kvedar, MD, is a Harvard Medical School researcher and the editor of  NPJ Digital Medicine. He’s been studying digital health systems and called clinical research a “beachhead” for the use of data from monitors. But he also said problems remain that need to be worked out. The quality of the devices and their Bluetooth connections are better. But different devices measure different things, and a counted step can vary from person to person, he said. And the problems of the early days of electronic health records have not been fully resolved.

“We haven’t gotten to this universal language to connect all these things and make them relevant,” he said. 

The All of Us researchers are working with the RECOVER project to address some of those issues. Usually not focused on a single condition, the All of Us researchers are testing a machine-learning approach for identifying long COVID.

But not everyone has room in their budget for a smartwatch or a fitness tracker. Until recently, most clinical trials were BYOD: Bring your own device. At a time when researchers are trying to make sure that clinical trials reflect the diversity of the population, that leaves a lot of people out.

So, researchers are starting to supply subjects with their own monitors. The RECOVER Initiative expects to give out 10,000 sensors to people who are eligible based on race/ethnicity, income, and other demographic factors (rural residents for example). After 2 months, all people in the RECOVER study over the age of 13 will be eligible for the sensors.

The federal program builds on earlier research at places like The Scripps Institute, a center of research into remote monitoring. The institute supplied 7,000 monitors to people in an arm of the All of Us study, a 5-year-old multisite cohort that aims to collect medical information from 1 million people. 

The devices went to people who have been historically underrepresented in biomedical research, said Scripps researchers, who plan to give out more this year. 

In March of 2023, Scripps researchers published a study on the tracking data that found a significant post-COVID-19 drop in physical activity. But the data are incomplete because many people can’t always afford these devices. Most of the people in the study were “White, young, and active,” they wrote.

Researchers at an All of Us site at Vanderbilt University, which also used a BYOD approach, realized that they produced biased results. They reported their findings at the Pacific Symposium on Biocomputing in January.

“[The] majority of participants who provided Fitbit data reported being White and employed for wages,” they said. “However, these data represent participants who had their own Fitbit devices and consented to share EHR [electronic health record] data.”

Their solution: The program has begun providing Fitbit devices to all study participants who do not own one or cannot afford one. 

Now, the web page for the All of Us study asks visitors to “Learn about the All of Us WEAR study. You could get a Fitbit at no cost! … As a part of the WEAR Study, you could receive a new Fitbit to wear at no cost to you. All of Us will be able to get the data the Fitbit collects. This data may help us understand how behavior impacts health.”

Jennifer Radin, PhD, an epidemiologist at Scripps Research Translational Institute, is heading up the DETECT study, which is a remote monitoring research project that has enrolled over 40,000 people who have their own sensors – be it a smartwatch or Fitbit. She was looking at remote monitoring for disease before COVID emerged.

Dr. Radin said she began researching remote sensing after working in public health and dealing with outdated data collection systems. 

“They typically rely on case reports that are recorded by pen and paper and faxed or mailed in,” she said. “Then, they have to be entered into a database. “

In addition to offering objective data on a subject’s physical response to the infection, she said, the data collection can be long-term and continuous. 

DETECT collects data on resting heart rate, which is unique to every person, and activity levels. Both measures are meaningful for those with long COVID. Her research found differences in sleep, heart rate, and activity between those with COVID and those without.

Joseph Kvedar, MD, is a Harvard Medical School researcher and the editor of  NPJ Digital Medicine. He’s been studying digital health systems and called clinical research a “beachhead” for the use of data from monitors. But he also said problems remain that need to be worked out. The quality of the devices and their Bluetooth connections are better. But different devices measure different things, and a counted step can vary from person to person, he said. And the problems of the early days of electronic health records have not been fully resolved.

“We haven’t gotten to this universal language to connect all these things and make them relevant,” he said. 

The All of Us researchers are working with the RECOVER project to address some of those issues. Usually not focused on a single condition, the All of Us researchers are testing a machine-learning approach for identifying long COVID.

There have been increases in suspected suicidal cannabis exposures reported to U.S. poison control centers over the past 13 years. The increases were notable both during and after the pandemic and were highest among children and female persons.

Investigators examined closed cases of cannabis-related human exposures that were coded as intentional-suspected suicidal.

Of note, there was a statistically significant increase in cannabis poisonings in young children (5-13 years) in 2021, during the pandemic, compared with 2019, a prepandemic year (3.1% vs. 1.3%; P < .001), the researchers report.

“This may speak to both increased access to cannabis as well as poor mental health status during the pandemic period,” study investigator Tracy Klein, PhD, assistant director, Center for Cannabis Policy, Research and Outreach, Washington State University Vancouver, Mount Vista, said in an interview.

The study was published online  in JAMA Network Open.

Reports of intentional poisonings with cannabis increased by roughly 17% annually over the study period. Most cases occurred in recent years and involved individuals aged 14-64 years. Nearly all (96.5%) cases involved more than one substance.

“The resemblance of cannabis edibles, implicated in the majority of poisonings to candy, vitamins, and food products, is a risk to patients across the life span who may not fully understand what they are consuming or how potent it is,” Dr. Klein said in an interview.

Overall, nearly 1 in 10 exposures resulted in death or other major outcomes (life-threatening outcomes or outcomes involving major residual disability or disfigurement). For older adults, 19.4% of exposures led to death or other major harm.

“Elderly patients may also have comorbid conditions and polypharmacy, which contributes to their much more serious outcomes from cannabis poisoning,” Dr. Klein said.

The researchers caution that, owing to the cross-sectional nature of the data, they could not identify a causal association between cannabis use and suicide attempt.

With more states legalizing cannabis use by adults, increases in cannabis use will likely persist.

“It is important to further examine the suspected association between cannabis use and suicidal behaviors and how risks can be prevented or mitigated,” the researchers note.

Dr. Klein encourages health care providers to ask patients whether they are using cannabis and how they obtain and store it.

“As with all medications and substances, storage is a key safety issue that is elicited during a careful history,” said Dr. Klein.

Support for the study was provided in part by funds provided for medical and biological research by the State of Washington Initiative Measure No. 171. Dr. Klein has disclosed no relevant financial relationships.

In a phase 2 clinical trial of a potential treatment for fatigue associated with long COVID-19, people who received the medicine reported positive results over those receiving a placebo.

The study was conducted by researchers at the University of Oxford, England, and published in eClinical Medicine.

It was one of the first randomized double-blind placebo controlled trial for a possible treatment for long COVID, according to a press release from the university. 

“People living with long COVID in the trial who received AXA1125 had a significant improvement in fatigue compared to those who received a placebo,” the university reported.

Forty-one people participated. They had fatigue for 18 months beforehand. All completed the study, and none reported serious side effects.

AXA1125 was developed by U.S. pharmaceutical company Axcella Therapeutics.

“Potential causes [of long COVID fatigue] include reduced mitochondrial function and cellular bioenergetics,” the researchers reported.

“AXA1125 was tested in long COVID fatigue as previous data from Axcella showed effects on cellular energetics and inflammation. Emerging data on long COVID suggests that the virus targets the mitochondrial, which are essential to normal energy generation and control of inflammation,” the university noted in its press release. “AXA1125 may improve energy generation and reduce the amount of inflammation in the body.”

The study’s authors wrote that AXA1125 was tied to a “significant reduction in 28-day Chalder Fatigue Questionnaire score relative to placebo.” They said participants who reported less fatigue also had better mitochondrial health and walked farther in a 6-minute test.
