Harmony pulmonary valve update: Regurgitation resolved 1 year out
The 1-year results of the Harmony transcatheter pulmonary valve to treat severe pulmonary regurgitation have shown a high rate of eliminating or reducing the degree of symptoms as well as freedom from endocarditis, sustained ventricular tachycardia, and the need for further interventions.
“Simply put, the good news is no endocarditis,” said Daniel S. Levi, MD, in presenting results from three different studies with 108 patients who received three different iterations of the device at the Society for Cardiovascular Angiography & Interventions annual scientific sessions.
“Endocarditis has been an issue for us in the pulmonary position; we have yet to have an endocarditis in these patients in 1 year,” he stressed.
The studies evaluated three different versions of the Harmony valve: TPV22 (42 patients), the first version with a 22-mm diameter; the Clinical TPV25 (17 patients), the first iteration of a 25 mm–wide device that has since been discontinued; and the modified TPV25 (45 patients), the second version of the 25-mm valve. The three studies are the early feasibility study of the TPV22, the continued-access study of the TPV22 and the mTPV25, and the pivotal study that included all three versions.
At baseline, 89% of patients had severe and 11% had moderate pulmonary regurgitation (PR). At 1 year, 92% had none or trace PR, 3% had mild PR, and 4% moderate disease.
Dr. Levi said the device “speaks for itself” in the results he presented. They include no deaths, no heart attacks, and no pulmonary thromboembolism. Other key outcomes include:
- One major stent fracture in one of the early feasibility study patients at 1-month follow-up.
- Four explants, with two in the discontinued cTPV25 and two with the TPV22 in the early-feasibility study.
- Four reinterventions, two with the discontinued cTPV25 and two valve-in-valve procedures with the mTPV25 in the continued-access study, one with stent placement in the right ventricular outflow tract.
Dr. Levi and coinvestigators also performed a breakdown of 1-year outcomes – freedom from PR, stenosis, and interventions – by device: 95.1% for TPV22; 89.7% for mTPV25; and 73.3% for the discontinued cTPV25.
Although the valve is indicated for adolescents and adults, most of the patients in the three studies were adults, with an average weight of 165 pounds (75 kg) who have had PR for decades, said Dr. Levi, an interventional pediatric cardiologist at the University of California, Los Angeles. “With a device like this we are hopefully shifting to treating that a little bit earlier, but fortunately we don’t usually need to treat it before puberty.” The 25-mm TPV gives “a really nice landing zone” for future valve placement. “The goal is to keep patients out of the operating room for at least a few decades if not their whole lives,” he said.
Dr. Levi said the Harmony investigators will follow outcomes with the 22- and modified 25-mm Harmony valves, both of which remain commercially available, out to 10 years.
The study represents the first collective cohort evaluating the Harmony device across the early feasibility, continued access and pivotal studies, said Brian Morray, MD. “It’s important that people understand that evolution and how that impacts the way we look at outcomes, because when you aggregate the data, particularly for the TPV25, some of the procedural outcomes and the adverse events are no longer really reflective in the current time frame.”
These Harmony results “represent another big step in the evolution of interventional cardiology and will be up there with development of the Melody valve and the utility and the use of the Sapien valve in the pulmonary position,” said Dr. Morray, an associate professor of pediatrics at the University of Washington, Seattle, and an interventional cardiologist at Seattle Children’s Hospital.
Dr. Levi disclosed he is a consultant to Medtronic and Edwards Lifesciences. Dr. Morray disclosed he is a clinical proctor for Abbott and a consultant to Medtronic, but not for the Harmony device.

COVID tied to a profound impact on children’s sleep
During the first year of the pandemic, profound changes in screen use and sleep timing occurred among U.S. adolescents as a result of spending more time using electronic devices, going to bed later, and getting up later, compared with before the pandemic, new research indicates.
The excessive screen time negatively affected sleep, said lead investigator Orsolya Kiss, PhD, with the Center for Health Sciences at SRI International, Menlo Park, Calif.
And what’s “concerning,” she told this news organization, is that there is no indication of any spontaneous decline in screen use in 2021, when there were fewer restrictions.
Dr. Kiss said she is “very much interested to see what future studies will show.”
The findings were presented at the annual meeting of the Associated Professional Sleep Societies.
Sleep takes a pandemic hit
“Adolescents and families have turned to online activities and social platforms more than ever before to maintain wellbeing, [to] connect with friends and family, and for online schooling,” Dr. Kiss said in a conference statement.
She and her colleagues examined longitudinal data from 5,027 adolescents aged 11-14 years who are participating in the ongoing Adolescent Brain Cognitive Development (ABCD) study.
As part of the study, participants reported sleep and daily screen time use prior to and at six time points during the first year of the pandemic (May 2020 to March 2021).
During the first year of the pandemic, relative to before the pandemic, recreational screen time was dramatically higher, with adolescents spending about 45 minutes more on social media and 20 minutes more playing video games, Dr. Kiss reported.
The jump in screen time was coupled with changes in sleep patterns.
Adolescents’ wake up times were delayed about 1.5 hours during May and August 2020, relative to prepandemic levels. The delay was partly due to summer break; wake-up times returned to earlier times in the fall of 2020.
During all pandemic assessments, bedtimes were delayed by about 1 hour, even when the new school year started. This was particularly the case in older adolescents and girls.
The findings highlight the need to promote “balanced and informed use of social media platforms, video games, and other digital technology to ensure adequate opportunity to sleep and maintain other healthy behaviors during this critical period of developmental change,” the authors wrote in their conference abstract.
Mental illness risk
In an interview, Ruth Benca, MD, PhD, co-chair of the Alliance for Sleep, noted that “during adolescence, the tendency to become more of a night owl naturally worsens, and when kids have no sleep schedule imposed on them, these patterns become exacerbated.”
Dr. Benca, who was not involved in the study, also noted that altered sleep patterns are risk factors for psychiatric illness.
“Adolescence, in particular, is so critical for brain development, and it really raises the question of whether sleep disturbances in adolescence or poor sleep patterns are contributing to the increase psychiatric epidemic we’re seeing in adolescents and children these days,” said Dr. Benca, with Wake Forest University School of Medicine and Atrium Health Wake Forest Baptist, Winston-Salem, N.C.
Also weighing in on the study, journalist and author Lisa Lewis, MS, based in Southern California, said, “It’s not surprising that tech use and social media – which is such an important part of their social worlds – went up during the pandemic.”
Ms. Lewis, a parent of two teenagers, played a key role in California’s new healthy school start times law, the first of its kind in the nation, and is the author of the newly released book, The Sleep-Deprived Teen (Mango Publishing).
“Far too many adolescents aren’t getting anywhere close to the 8-10 hours of nightly sleep they need,” Ms. Lewis said in an interview.
She noted that the the American Academy of Pediatrics recommends no tech use an hour before bed.
“And there are other house rules parents can implement, such as charging all devices in a central location, like the kitchen. Making sleep a priority helps teens, but it helps parents too: No one functions well when they’re sleep-deprived,” Ms. Lewis added.
Support for the study was provided by the National Institutes of Health. The authors have disclosed no relevant financial relationships. Dr. Benca is a consultant for Idorsia Pharmaceuticals. Ms. Lewis has no relevant disclosures.

FDA warning released for Volara respiratory system
The Food and Drug Administration published a warning from the medical device company Baxter International, citing problems with their device used for at-home respiratory therapy. The release cautions Volara system users that using certain therapies from the device may cause a change in lung pressure and a decrease in oxygen level. This cautionary warning was issued following a single reported case of oxygen loss while using the device.
The Volara system is meant to help patients with persistent pulmonary problems who are transitioning from the hospital to the outpatient setting. It can connect to three pieces commonly used in treating the respiratory conditions – a tracheostomy tube, a mask, and an in-line ventilator. The device offers three therapies – one to expand lungs (OLE), one to shake mucus from the lungs (CHFO), and a nebulizer to deliver medication.
This particular warning is relevant only to patients who use the system with an in-line ventilator or to patients who use OLE and CHFO therapies. The concern is that a rapid change in lung pressure (barotrauma), could damage the tissue by overextending the surface of the organ. Additionally, as noted in the reported case, Volara users may be at risk for a decrease in the level of oxygen while using the device (oxygen desaturation).
If patients have been directed to use Volara by a physician, the FDA recommends they continue to use it as prescribed. But they should look out for signs of respiratory distress. These include changes in alertness, the appearance of a blue tint around the mouth, increased breathing rate, and wheezing. If a patient or caregiver sees these signs, the patient should stop using Volara immediately and should seek help if their symptoms don’t improve.
In response to these precautions, Baxter says it will update the instructions for the use of its device and will add additional warnings. The company says it will dispatch a trainer to patients’ homes to help them understand the newest guidelines.
Both the FDA and Baxter urge patients who have experienced any problems with the device to report it to the hotlines listed at the bottom of their release.

FDA: Urgent device correction, recall for Philips ventilator
The U.S. Food and Drug Administration has announced a Class I recall for Philips Respironics V60 and V60 Plus ventilators, citing a power failure leading to potential oxygen deprivation. Class I recalls, the most severe, are reserved for devices that may cause serious injury or death, as noted in the FDA’s announcement. As of April 14, one death and four injuries have been associated with this device failure.
These ventilators are commonly used in hospitals or under medical supervision for patients who have difficulty regulating breathing on their own. Normally, if oxygen flow is interrupted, the device sounds alarms, alerting supervisors. The failure comes when a power fluctuation causes the device to randomly shut down, which forces the alarm system to reboot. This internal disruption is the reason for the recall.
When the device shuts down out of the blue, it may or may not sound the requisite alarm that would allow providers to intervene. If the device does not sound the alarm, patients may lose oxygen for an extended period, without a provider even knowing.
Philips was notified of these problems and began the recall process on March 10. Currently, it is estimated that 56,671 devices have been distributed throughout the United States. The FDA and Philips Respironics advise that if providers are already using these ventilators, they may continue to do so in accordance with extra set of instructions.
First, customers should connect the device to an external alarm or nurse call system. Second, they should use an external oxygen monitor and a pulse oximeter to keep track of air flow. Finally, if one is available, there should be a backup ventilator on the premises. That way, if there is an interruption in oxygen flow, someone will be alerted and can quickly intervene.
If there is a problem, the patient should be removed from the Philips ventilator and immediately placed on an alternate device. The FDA instructs customers who have experienced problems to report them to its MedWatch database.

First, customers should connect the device to an external alarm or nurse call system. Second, they should use an external oxygen monitor and a pulse oximeter to keep track of air flow. Finally, if one is available, there should be a backup ventilator on the premises. That way, if there is an interruption in oxygen flow, someone will be alerted and can quickly intervene.
If there is a problem, the patient should be removed from the Philips ventilator and immediately placed on an alternate device. The FDA instructs customers who have experienced problems to report them to its MedWatch database.

The U.S. Food and Drug Administration has announced a Class I recall for Philips Respironics V60 and V60 Plus ventilators, citing a power failure leading to potential oxygen deprivation. Class I recalls, the most severe, are reserved for devices that may cause serious injury or death, as noted in the FDA’s announcement. As of April 14, one death and four injuries have been associated with this device failure.
These ventilators are commonly used in hospitals or under medical supervision for patients who have difficulty regulating breathing on their own. Normally, if oxygen flow is interrupted, the device sounds alarms, alerting supervisors. The failure comes when a power fluctuation causes the device to randomly shut down, which forces the alarm system to reboot. This internal disruption is the reason for the recall.
When the device shuts down out of the blue, it may or may not sound the requisite alarm that would allow providers to intervene. If the device does not sound the alarm, patients may lose oxygen for an extended period, without a provider even knowing.

Parkinson’s disease could be hiding behind those nightmares
Living the dream, diagnosing the nightmare
Does a bad dream mean you should be consulting your doctor about an impending neurologic disease? Maybe.
New research published in eClinicalMedicine suggests that, for some people, bad dreams and nightmares have been associated with developing Parkinson’s disease later in life. Dr. Abidemi I. Otaiku of the University of Birmingham (England) analyzed data from a cohort study involving 3,818 older men, of whom 2.3% were diagnosed with Parkinson’s during the 12 years of follow-up.
Dr. Otaiku found those with frequent nightmares – at least once per week – were twice as likely to develop Parkinson’s than were those without, with most of the diagnoses coming in the first 5 years.
Although more research needs to be done, “identifying the significance of bad dreams and nightmares could indicate that individuals who experience changes to their dreams in older age – without any obvious trigger – should seek medical advice,” he said in a Eurekalert statement.
Dr. Otaiku pointed out that studying dreams can tell us a lot about how our brains work and are structured. By using electroencephalography, Dr. Otaiku plans to look into the biological reasons for why we dream the way we do.
So could it be that those killer clowns are actually giving you a heads up on your health?
Maybe next time try a paper route
There’s just no winning with teenagers sometimes. You tell them to go outside, they’ll sit in the dark playing video games all night. You tell them to get better grades, they’ll skip school. You tell them to get a hobby, they’ll scam the German government for millions of euros.
The COVID-19 pandemic has been tricky for governments to manage. Massive amounts of infrastructure needed to be set up, and that means corners got cut. Germany was no exception in this regard; the government entrusted the Kassenärztlichen Vereinigung, a doctor’s association, with overseeing COVID testing and payment at private test centers. To make things a bit easier, all they required private test centers to provide to receive reimbursement was an invoice.
This is where our 17-year-old from Freiburg comes in. In a spark of entrepreneurial genius, he decided to falsify documents and create an entirely fictional COVID test center. The KV approved it, and between March and July of 2021, he sent in thousands of fake invoices. Over that 4-month period, he submitted 500,000 invoices and received 5.7 million euros as compensation. That’s a few thousand tests per day, which was absolutely absurd, but he avoided scrutiny for months.
In the end, it wasn’t even the KV that noticed the fraud, but the bank. A bank employee noticed millions flowing into the account of a teenager and suspected money laundering, alerting the government. Fortunately for our young friend, since he was under 18 when he hatched his scheme, he was tried as a minor, avoiding jail time. His ill-gotten gains were confiscated, he has to pay a relatively minimal fine, and he will be on probation for 1 year. And presumably, he’ll be on the receiving end of the grounding of a lifetime.
You look like I need more sleep
Like most people, not getting our beauty sleep can make us look tired and feel less attractive, but a new study from Sweden shows that the sleep deprived also are more likely to find others less attractive. That’s probably not a good finding for singles who often go out trying to meet someone after a long day of work.
For the study, 45 young men and women were required to spend one night with no sleep and then another night with the possibility of 8 hours of sleep. The following mornings, eye-tracking technology was used as they looked at images of happy, angry, fearful, and neutral faces. The subjects then rated the faces for attractiveness, trustworthiness, and healthiness.
“The finding that sleep-deprived subjects in our experiment rated angry faces as less trustworthy and healthy-looking and neutral and fearful faces as less attractive indicates that sleep loss is associated with more negative social impressions of others,” senior author Christian Benedict of Uppsala University said in a statement.
When we are sleep deprived, the researchers added, we might not stop to really look at someone else, which has a negative impact on how we perceive people because we are not focusing on what their facial expressions are really telling us.
We already knew that not sleeping well has many negative effects on us, but now – thank you very much, science – we have something else to think about. Better hope your crush at work gets enough sleep so you’ll be accurately noticed.
The expanding-hole illusion of science
Time for a LOTME-style reality check: I think, therefore I am.
So far, so good. Next step: I think, therefore I am. I think.
Works for us. Now for the biggie: I think I am seeing the black hole in the middle of this image expanding.
Does that work for you? Do you perceive the black hole as expanding? If you do, then you fit in with the 86% of subjects in a recent study who perceived the same thing.
Lead author Bruno Laeng of the University of Oslo explained the effect in a statement from Frontiers Science News. “The circular smear or shadow gradient of the central black hole evokes a marked impression of optic flow, as if the observer were heading forward into a hole or tunnel. ... The pupil reacts to how we perceive light – even if this ‘light’ is imaginary like in the illusion – and not just to the amount of light energy that actually enters the eye.”
The illusion is so good at deceiving the brain “that it even prompts a dilation reflex of the pupils to let in more light, just as would happen if we were really moving into a dark area,” the investigators said.
Of the 50 men and women who had their eye movements measured while looking at the illusion, only 14% didn’t perceive the illusion when the hole was black. When the hole was a color, that figure went up to 20%. There also was a strong dilation reflex with black holes, but colored holes caused the subjects’ pupils to constrict, they noted.
Dr. Laeng and his associates can’t explain why some people don’t see the movement, but they did offer this: “Pupils’ dilation or contraction reflex is not a closed-loop mechanism, like a photocell opening a door, impervious to any other information than the actual amount of light stimulating the photoreceptor. Rather, the eye adjusts to perceived and even imagined light, not simply to physical energy.”
And now, back to our reality check: We think we perceive the light of a cheeseburger, therefore it’s time for lunch.

‘Alarming’ new data on disordered sleep after COVID-19
Such disturbances are especially common among Black people, new research shows.
The “high” prevalence of moderate to severe sleep disturbances is “alarming,” study investigator Cinthya Pena Orbea, MD, sleep specialist at the Cleveland Clinic, said in an interview.
The findings were presented at the annual meeting of the Associated Professional Sleep Societies.
Dr. Pena and colleagues analyzed data on 962 patients with PASC seen at the Cleveland Clinic ReCOVer Clinic between February 2021 and April 2022.
More than two-thirds of patients (67.2%) reported at least moderate fatigue, while 21.8% reported severe fatigue, Dr. Pena reported.
In addition, 41.3% reported at least moderate sleep disturbances, while 8% of patients reported severe sleep disturbances, including insomnia, “which may impair quality of life,” Dr. Pena said.
Obesity, mood disorders, and Black race emerged as contributors to problems with sleep and fatigue after COVID.
Notably, after adjusting for demographics, Black race conferred threefold higher odds of moderate to severe sleep disturbances.
“We don’t know why this is, and one of our next steps is to better understand race-specific determinants of sleep disturbances after COVID and create targeted interventions,” Dr. Pena said.
How long after COVID the fatigue and sleep problems last “remains uncertain,” Dr. Pena acknowledged. However, in her clinical experience with therapy, patients’ sleep and fatigue may improve after 6 or 8 months.
Ruth Benca, MD, PhD, cochair of the Alliance for Sleep, is not surprised by the Cleveland Clinic findings.
“Sleep disturbances and fatigue are part of the sequelae of COVID,” Dr. Benca, who was not involved in the study, said in an interview.
“We know that people who have had COVID have more trouble sleeping afterwards. There is the COVID insomnia created in all of us just out of our worries, fears, isolation, and stress. And then there’s an actual impact of having the infection itself on worsening sleep,” said Dr. Benca, with Wake Forest University and Atrium Health Wake Forest Baptist, both in Winston-Salem, N.C.
The study had no specific funding. The authors have disclosed no relevant financial relationships. Dr. Benca is a consultant for Idorsia Pharmaceuticals.

FROM SLEEP 2022
Substance use the main cause of physician license actions
Despite a sharp uptick in 2011, substance use–specific license actions taken against physicians dropped in frequency between 2004 and 2020.
More than three fourths (76.3%) of license actions taken against physicians were related to substance use, according to a recent study published in JAMA. Psychological impairment was the reason associated with more than 1 in 10 (11.5%) actions taken against physicians’ licenses, while physical impairment was the reason behind approximately 12% of such actions, per the study.
Researchers analyzed 5032 actions taken against the licenses of U.S. physicians. The actions were reported to the National Practitioner Data Bank and were related to substance use, psychological impairment, and physical impairment. The National Practitioner Data Bank is a web-based repository of reports with information on medical malpractice payments and certain adverse actions related to healthcare practitioners, providers, and suppliers. It is provided by the Department of Health & Human Services.
“While there has been increased attention [on] the mental health of physicians, we wanted to understand the extent to which changes in attitudes and practices were reflected in actions taken by hospitals or licensing boards, which are reported in the National Practitioner Data Bank,” Lisa Rotenstein, MD, a primary care physician at Boston’s Brigham and Women’s Hospital and lead author of the study, told this news organization.
Dr. Rotenstein, who is an assistant professor at Harvard Medical School, Boston, studies issues of mental health among physicians and trainees. Dr. Rotenstein was the lead author of a 2016 study that found that more than a quarter (27.2%) of medical students have depressive symptoms. She was also lead author of a 2018 study published in JAMA on the prevalence of burnout among attending physicians.
Actions against physicians trending downward
2011 marked the peak in actions taken against physicians’ licenses for substance use, per the study, but actions related to substance use have otherwise maintained a steady decline over the past 17 years. Researchers found that physicians with license actions as a result of substance use or psychological impairment were more likely to receive indefinite penalties, while also having emergency action taken against their license to practice.
In addition, physicians who had actions taken against their licenses because of substance use or psychological impairment were more likely to accrue a greater number of actions over the course of their careers, according to the study.
About 47% of physicians reported experiencing burnout per Medscape’s Physician Burnout and Depression Report 2022: Stress, Anxiety, and Anger report. Burnout among emergency physicians spiked from 43% in 2020 to 60% in 2021, according to the report.
More than one quarter (26%) of physicians reported drinking alcohol to cope with burnout in 2020, according to Medscape’s 2021 Physician Burnout and Suicide Report. Per the 2021 report, 48% of physicians chose exercise to deal with burnout, while 35% indulged in eating junk food.
Peter Grinspoon, MD, a Boston-based primary care physician, wrote in The Los Angeles Times in 2016 that the rate of substance abuse among physicians starts at 10% and can go as high as 15%; by comparison, rates of substance use among the general population are 8%-10%. “What appears to account for the difference is physician distress, and in the case of drug abuse, plentiful access,” he added.
Dr. Grinspoon wrote a 2016 book called “Free Refills: A Doctor Confronts His Addiction,” which chronicles his experience in recovery and relapse as a physician who was dependent on opioid painkillers.
The findings from the recent study in JAMA “suggest we have made some progress in addressing issues related to substance use in ways that don’t result in license actions or even in meeting physicians’ need for support related to substance use,” said Dr. Rotenstein.
Still, she insists that there’s “substantial opportunity to improve mental health and support offerings for physicians and to reduce stigma related to seeking and receiving mental health support, ideally averting the need for license actions.”
According to Dr. Rotenstein, the cases listed in the National Practitioner Data Bank represent the most severe cases; these reports have risen to a high level of attention or concern and are the result of adverse action reports submitted by healthcare institutions and state licensing boards.
“There are many, many more physicians whose cases are not represented here but who struggle with depression, anxiety, substance use, and more,” said Dr. Rotenstein.

2011 marked the peak in actions taken against physicians’ licenses for substance use, per the study, but actions related to substance use have otherwise maintained a steady decline over the past 17 years. Researchers found that physicians with license actions as a result of substance use or psychological impairment were more likely to receive indefinite penalties, while also having emergency action taken against their license to practice.
In addition, physicians who had actions taken against their licenses because of substance use or psychological impairment were more likely to accrue a greater number of actions over the course of their careers, according to the study.
About 47% of physicians reported experiencing burnout per Medscape’s Physician Burnout and Depression Report 2022: Stress, Anxiety, and Anger report. Burnout among emergency physicians spiked from 43% in 2020 to 60% in 2021, according to the report.
More than one quarter (26%) of physicians reported drinking alcohol to cope with burnout in 2020, according to Medscape’s 2021 Physician Burnout and Suicide Report. Per the 2021 report, 48% of physicians chose exercise to deal with burnout, while 35% indulged in eating junk food.
Peter Grinspoon, MD, a Boston-based primary care physician, wrote in The Los Angeles Times in 2016 that the rate of substance abuse among physicians starts at 10% and can go as high as 15%; by comparison, rates of substance use among the general population are 8%-10%. “What appears to account for the difference is physician distress, and in the case of drug abuse, plentiful access,” he added.
Dr. Grinspoon wrote a 2016 book called “Free Refills: A Doctor Confronts His Addiction,” which chronicles his experience in recovery and relapse as a physician who was dependent on opioid painkillers.
The findings from the recent study in JAMA “suggest we have made some progress in addressing issues related to substance use in ways that don’t result in license actions or even in meeting physicians’ need for support related to substance use,” said Dr. Rotenstein.
Still, she insists that there’s “substantial opportunity to improve mental health and support offerings for physicians and to reduce stigma related to seeking and receiving mental health support, ideally averting the need for license actions.”
According to Dr. Rotenstein, the cases listed in the National Practitioner Data Bank represent the most severe cases; these reports have risen to a high level of attention or concern and are the result of adverse action reports submitted by healthcare institutions and state licensing boards.
“There are many, many more physicians whose cases are not represented here but who struggle with depression, anxiety, substance use, and more,” said Dr. Rotenstein.

Despite a sharp uptick in 2011, substance use–specific license actions taken against physicians dropped in frequency between 2004 and 2020.
More than three fourths (76.3%) of license actions taken against physicians were related to substance use, according to a recent study published in JAMA. Psychological impairment was the reason associated with more than 1 in 10 (11.5%) actions taken against physicians’ licenses, while physical impairment was the reason behind approximately 12% of such actions, per the study.
Researchers analyzed 5032 actions taken against the licenses of U.S. physicians. The actions were reported to the National Practitioner Data Bank and were related to substance use, psychological impairment, and physical impairment. The National Practitioner Data Bank is a web-based repository of reports with information on medical malpractice payments and certain adverse actions related to healthcare practitioners, providers, and suppliers. It is provided by the Department of Health & Human Services.
“While there has been increased attention [on] the mental health of physicians, we wanted to understand the extent to which changes in attitudes and practices were reflected in actions taken by hospitals or licensing boards, which are reported in the National Practitioner Data Bank,” Lisa Rotenstein, MD, a primary care physician at Boston’s Brigham and Women’s Hospital and lead author of the study, told this news organization.
Dr. Rotenstein, who is an assistant professor at Harvard Medical School, Boston, studies issues of mental health among physicians and trainees. Dr. Rotenstein was the lead author of a 2016 study that found that more than a quarter (27.2%) of medical students have depressive symptoms. She was also lead author of a 2018 study published in JAMA on the prevalence of burnout among attending physicians.

FDA panel strongly backs protein-based Novavax COVID-19 vaccine
than the cutting-edge technology used in mRNA-based shots.
The Vaccines and Related Biological Products Advisory Committee of the Food and Drug Administration voted almost unanimously June 7 in favor of Novavax’s two-dose COVID-19 vaccine for those 18 or older – despite some concerns over rare events of myocarditis and pericarditis.
The tally was 21 “yes” votes, without any “no” votes, but one abstention from a panelist who then offered a largely positive take on this vaccine.
Panelist Bruce Gellin, MD, explained at the end of the meeting that he would have cast a conditional vote in favor of the Novavax vaccine, called NVX-CoV2373, had that been an option. Dr. Gellin, chief of global public health strategy for the Rockefeller Foundation and a vaccine expert, said he didn’t want his abstention to be considered as signaling opposition to the Novavax shot.
Instead, he said, he expects FDA officials will gather more data and evidence about the Novavax vaccine, especially in relation to certain manufacturing issues, before making its decision on the company’s application.
Earlier in the day, a top FDA vaccine reviewer, Doran Fink, MD, PhD, noted that there were important manufacturing differences between the Novavax vaccine supply used in different projects, complicating efforts to assess the company’s application for emergency use authorization (EUA).
But Dr. Fink noted that the FDA staff already had made a convincing case in its briefing document, with enough evidence for an initial conditional clearance to be found in available data.
The FDA is not bound to follow the suggestions of its advisory committees but it often does.
Using the ‘bully pulpit’
At the beginning of the meeting, Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, said he was seizing the “bully pulpit” in addressing the need to persuade more people in the United States to take shots against COVID-19.
About 67% of people in the United States aged 18 and older are fully vaccinated, but only about 50% of those in this group have had a first booster, according to the Centers for Disease Control and Prevention.
The two-dose mRNA vaccines from Pfizer and Moderna have been the subject of intense misinformation campaigns on social media, despite efforts by the FDA and other public health officials to convey the message about their strong benefit-risk profile. The FDA in May limited the authorized use of Johnson & Johnson’s single-dose COVID-19 shot, which is based on a different technology, because of concerns about rare and potentially life-threatening blood clots.
Novavax has been described as a more traditional vaccine – a protein subunit shot similar to one people have long received for protection against influenza, pertussis (whooping cough), diphtheria, and tetanus.
“Having a protein-based alternative may be more comfortable for some in terms of their acceptance of vaccines,” Dr. Marks said. “We do have a problem with vaccine uptake that is very serious in the United States. And anything we can do to get people more comfortable to be able to accept these potentially life-saving medical products is something that we feel we are compelled to do.”
Dr. Marks offered these remarks in answer to an FDA panelist’s question about the need to consider an EUA for yet another vaccine.
EUAs are special clearances the FDA can grant in connection with public health emergencies such as the pandemic. The FDA used EUAs for the initial December 2020 clearances of the Pfizer-BioNTech and Moderna vaccines. It has since granted normal approvals for both of these mRNA-based vaccines, based on larger bodies of evidence gathered and submitted by their developers.
During the meeting, the FDA panelists in general appeared comfortable with the idea of granting another EUA for a vaccine. There was agreement that the shot appeared to work in key tests, although these were done before the rise of the Omicron variant.
In a key test, known as study 301, the Novavax vaccine was judged to be 90.4% effective. In the study, 17 of the 17,272 people who got the Novavax vaccine developed COVID-19, compared with 79 of the 8,385 in the placebo group.
Panelists expressed disappointment with the lack of information about how the shot would work now.
“We’re looking at the efficacy against strains that don’t exist any longer,” said panelist Eric J. Rubin, MD, PhD, a Harvard professor and editor of the New England Journal of Medicine.
Still, Dr. Rubin added that he agreed with the argument the FDA’s Dr. Marks had made earlier for an EUA for the Novavax vaccine.
“If there really is a population of patients who are willing to take this and not willing to take the existing vaccines, I think it’s pretty compelling,” Dr. Rubin said.
Other FDA panelists were skeptical of this argument. Jay Portnoy, MD, who was listed on the FDA roster as the panel’s consumer representative, said he has close friends who are vaccine skeptics.
“Their hesitancy is more ideological than technological,” said Dr. Portnoy of Children’s Mercy Hospital, Kansas City, Mo. “So I really doubt that this vaccine is going to crack that nut, but perhaps some individuals would get this when they wouldn’t get the other ones.”
Myocarditis, pericarditis
The Novavax vaccine is already authorized in other countries, including Canada. Novavax in February announced that it had begun shipping its first doses of the vaccine to European Union member states. The vaccine can be moved through existing vaccine supply and cold chain channels instead of requiring complex new delivery procedures.
That could prove an advantage in time, said FDA panelist Michael Nelson, MD, PhD, of the University of Virginia, Charlottesville.
“Who knows even with supply chain challenges down the road, it will be nice to have options going forward,” Dr. Nelson said.
As with other COVID-19 vaccines, clinicians and researchers are still working to understand the potential risk for inflammation of heart muscle and nearby tissue with vaccination. Most patients with myocarditis or pericarditis who sought medical care for these conditions responded well to medicine and rest and felt better quickly, the CDC says on its website. They usually return to their normal daily activities after their symptoms improve.
At the June 7 meeting, Dr. Nelson said there may be cases of myocarditis that go undetected.
“Our signals are those who get admitted to the emergency room and the hospital,” he said. “I’m quite convinced that there are others who are experiencing cardiac events of lesser severity that are worthy of being studied, both from mechanistic and outcomes standpoints. So we have a lot of work to do.”
In looking at results for an initial pool of 40,000 people who received the Novavax vaccine, there were five reported cases of myocarditis or pericarditis developing within 20 days of people getting the shot, the FDA staff said in its presentation on safety.
In a briefing document released ahead of the advisory committee meeting, the FDA staff flagged this number of cases in a relatively small database as a concern, noting it “could be higher than reported during postauthorization use of mRNA COVID-19 vaccines (for which no cases were identified in preauthorization evaluation).”
Novavax officials took a somewhat unusual step of responding in public. The Gaithersburg, Md.–based company on June 3 issued a statement saying researchers had come to “expect to see natural background events of myocarditis in any sufficiently large database, and that young males are at higher risk.”
The data from the company’s placebo-controlled studies show that, overall, in its clinical development program, the rate of myocarditis was balanced between the vaccine and placebo arms (0.007% and 0.005%), Novavax said.
At the June 7 meeting, FDA panelists including Dr. Nelson, and Paul A. Offit, MD, of Children’s Hospital of Philadelphia, urged continued study to try to determine whether and how the vaccines could trigger myocarditis. Investments made now in pursuing these questions related to COVID-19 shots may pay off later, Dr. Offit said.
“We can use that knowledge to make safer vaccines for a disease that is going to be with us for decades, if not longer,” he said.

Children and COVID: Cases down, start of vaccinations near
The first decline in COVID-19 cases among children since early April may have been holiday related, but the shortened week also brought news about vaccination for the youngest children.
The Food and Drug Administration has accepted Pfizer’s application for a COVID-19 vaccine for children under age 5, so vaccination could begin as early as June 21, according to White House COVID-19 response coordinator Ashish Jha, MD.
“We know that many, many parents are eager to vaccinate their youngest kids and it’s important to do this right,” Dr. Jha said at a White House press briefing June 2. “We expect that vaccinations will begin in earnest as early as June 21 and really roll on throughout that week.”
Decline may just be underreporting
Over on the incidence side of the pandemic, latest COVID report.
The decline in new cases was not spread uniformly across the four major regions of the United States. The count actually went up in the West for the week of May 27 to June 2, while the South saw the largest decline. The Midwest and Northeast, meanwhile, saw new cases drop for the second straight week, the AAP and CHA said.
The cumulative number of COVID-19 cases in children was up to 13.45 million as of June 2, with children representing 18.9% of all cases since the start of the pandemic, according to the two organizations. The Centers for Disease Control and Prevention reported figures of 13.14 million and 17.5% on June 6.
The AAP/CHA estimates, however, are based on state data that have become increasingly hard to obtain and subject to inconsistency. “Shortages of COVID-19 tests during surges and the increasing use of COVID-19 home tests likely affect the undercounting of COVID-19 cases,” they noted, and “at times when COVID-19 transmission is low, states might reduce the frequency information is updated.”
Vaccinations held steady over the holiday
The ongoing vaccination effort in children aged 5 years and older did not show a Memorial Day drop-off, as initial vaccinations held at 43,000 in 5- to 11-year-olds and at 27,000 in 12- to 17-year-olds for a second consecutive week. That number has ranged from 34,000 to 70,000 for the younger children and from 25,000 to 47,000 for the older group since mid-March, the AAP said in a separate weekly report.
Despite weekly vaccine initiations that have been roughly double those of the older children for months, the 5- to 11-year-olds are still only at 36.0% coverage with at least one dose, compared with 69.5% for the 12- to-17-year-olds. Full vaccination for the two age groups comes in at 29.3% and 59.6%, respectively, as of June 6, according to the CDC’s COVID Data Tracker.

The cumulative number of COVID-19 cases in children was up to 13.45 million as of June 2, with children representing 18.9% of all cases since the start of the pandemic, according to the two organizations. The Centers for Disease Control and Prevention reported figures of 13.14 million and 17.5% on June 6.
The AAP/CHA estimates, however, are based on state data that have become increasingly hard to obtain and subject to inconsistency. “Shortages of COVID-19 tests during surges and the increasing use of COVID-19 home tests likely affect the undercounting of COVID-19 cases,” they noted, and “at times when COVID-19 transmission is low, states might reduce the frequency information is updated.”
Vaccinations held steady over the holiday
The ongoing vaccination effort in children aged 5 years and older did not show a Memorial Day drop-off, as initial vaccinations held at 43,000 in 5- to 11-year-olds and at 27,000 in 12- to 17-year-olds for a second consecutive week. That number has ranged from 34,000 to 70,000 for the younger children and from 25,000 to 47,000 for the older group since mid-March, the AAP said in a separate weekly report.
Despite weekly vaccine initiations that have been roughly double those of the older children for months, the 5- to 11-year-olds are still only at 36.0% coverage with at least one dose, compared with 69.5% for the 12- to-17-year-olds. Full vaccination for the two age groups comes in at 29.3% and 59.6%, respectively, as of June 6, according to the CDC’s COVID Data Tracker.
The first decline in COVID-19 cases among children since early April may have been holiday related, but the shortened week also brought news about vaccination for the youngest children.
The Food and Drug Administration has accepted Pfizer’s application for a COVID-19 vaccine for children under age 5, so vaccination could begin as early as June 21, according to White House COVID-19 response coordinator Ashish Jha, MD.
“We know that many, many parents are eager to vaccinate their youngest kids and it’s important to do this right,” Dr. Jha said at a White House press briefing June 2. “We expect that vaccinations will begin in earnest as early as June 21 and really roll on throughout that week.”
Decline may just be underreporting
Over on the incidence side of the pandemic, latest COVID report.
The decline in new cases was not spread uniformly across the four major regions of the United States. The count actually went up in the West for the week of May 27 to June 2, while the South saw the largest decline. The Midwest and Northeast, meanwhile, saw new cases drop for the second straight week, the AAP and CHA said.

Adagrasib shows durable benefit in KRAS-mutated NSCLC
with previously treated, advanced non-small cell lung cancer (NSCLC) with tumors with KRAS G12C mutations.
“KRAS G12C mutations occur in over 10% of patients with NSCL [and] remain difficult to target, and outcomes for this patient population have remained poor,” co-investigator Joshua Sabari, MD, assistant professor of medicine, Perlmutter Cancer Center at NYU Langone, said in a statement.
“Our patients benefited clinically from this agent, and it appears to have improved overall survival (OS), compared with historical outcomes with docetaxel, a standard-of-care chemotherapy regimen, in the second-line setting,” he added.
New data on adagrasib were presented at the annual meeting of the American Society for Clinical Oncology and simultaneously published in the New England Journal of Medicine.
Adagrasib (developed by Mirati) is currently awaiting approval from the U.S. Food and Drug Administration as a treatment for patients with NSCLC harboring the KRAS G12C mutation who have received at least one prior systemic therapy. This would be an accelerated approval based on overall response data from the KRYSTAL-1 study detailed below. The company has an ongoing confirmatory Phase 3 trial, KRYSTAL-12, evaluating adagrasib versus docetaxel in patients previously treated for metastatic NSCLC with a KRAS G12C mutation.
If approved, adagrasib would be the second in this class of agents. The first KRASG12C inhibitor for use in lung cancer was sotorasib (Lumakras), approved by the U.S. Food and Drug Administration in May 2021.
Dr. Sabari noted that there are several differences between the two drugs. Adagrasib has CNS penetration and is the first KRASG12C inhibitor to demonstrate clinical activity in patients with KRAS G12C-mutated NSCLC with untreated active CNS metastases.
Published clinical data
The results published in the New England Journal of Medicine are from the company-funded KRYSTAL-1 clinical trial, which had the primary endpoint of objective response rate.
It was conducted in patients with KRAS G12C-mutated NSCLC who had previously received treatment with at least one platinum-containing chemotherapy regimen and checkpoint inhibitor therapy either sequentially or concurrently.
Patients were treated with oral adagrasib 600 mg twice a day until disease progression, unacceptable toxicity, or death.
On Oct. 15, 2021, the data cutoff date, a total of 116 patients had received at least one dose of adagrasib. At a median follow-up of 12.9 months, the confirmed objective response rate was 42.9% among 112 patients with measurable disease at baseline. One patient achieved a complete response: 42% achieved a partial response, and disease stabilized for a minimum of 6 weeks in over 36% of the group.
Only 5.4% of patients had progressive disease as their best overall response, investigators note. Among those patients who responded to twice-daily KRASG12C inhibition, the median time to response was 1.4 months and the median duration of response was 8.5 months. As of the data cutoff date, one-third of the group were still receiving treatment, the authors note.
Median progression-free survival (PFS) was 6.5 months and median OS was 11.7 months. With a longer median follow-up of 15.6 months, median OS was 12.6 months, and the estimated OS at 1 year was close to 51%.
“The majority of treatment-related adverse events were low-grade, started early in treatment, and quickly resolved after occurrence,” Dr. Sabari noted.
Grade 1-2 treatment-related adverse events occurred in 53% of patients while 45% had grade 3-4 treatment-related adverse events, and there were two fatal grade 5 treatment-related adverse events. The same events led to a dose reduction in 52% of the group overall and dose interruption in 61%, while in 7% of patients, treatment-related adverse events led to discontinuation of the drug.
CNS metastases
At baseline, some 42 patients had evidence of central nervous system (CNS) metastases. At a median follow-up of 15.4 months, an intracranial-confirmed objective response was achieved in one-third of this subgroup overall while median duration of the intracranial response was 11.2 months. Again, within the same subgroup, the median PFS was 5.4 months.
As Dr. Sabari noted, CNS metastases from KRAS mutant NSCLC are common. “Adagrasib demonstrated encouraging and durable CNS-specific activity in patients with KRAS G12C-mutant NSCLC and active, untreated CNS metastases,” he said.
The study was funded by Mirati Therapeutics.
