Temporal artery ultrasound alone was sufficient to accurately diagnose giant cell arteritis (GCA) in over half of patients in a new prospective study.

The findings provide further evidence that “[ultrasound] of temporal arteries could really take the place of traditional temporal artery biopsy (TAB)” in patients with high clinical suspicion of GCA, lead author Guillaume Denis, MD, of the Centre Hospitalier de Rochefort in Rochefort, France, told this news organization.

The European Alliance of Associations for Rheumatology (EULAR) already recommends ultrasound as a first-line diagnostic tool for patients with suspected large vessel vasculitis, and the 2022 American College of Rheumatology (ACR)/EULAR classification criteria for GCA weighs positive TAB or temporal artery halo sign on ultrasound equally.

Methodology

In the study, researchers recruited 165 individuals with high clinical suspicion of GCA from August 2016 through February 2020 at six French hospitals. Only patients older than 50 years of age and with biologic inflammatory syndrome with C-reactive protein elevation (≥ 6 mg/L) qualified for the study. Patients also needed to have at least one of these factors:

• Clinical signs of GCA (abnormal temporal arteries, scalp hyperesthesia, jaw claudication, or vision loss)
• General signs of GCA (headache, fever, or impaired general condition)
• Large-vessel vasculitis visible on imaging (CT angiography [CTA], MR angiography [MRA], and/or PET/CT)

All participants underwent a color Doppler ultrasound of the temporal artery, performed less than 1 week after the initiation of corticosteroid therapy. (Previous research demonstrated that corticosteroids can change the hallmark halo sign of vasculitis detectable via ultrasound as early as 1 week after initiation of therapy, the authors noted.) In this study, the time between consultation with a specialist and ultrasound was less than 1 day.

“Patients with halo signs detected around the lumen of both temporal arteries (that is, bilateral temporal halo sign) were considered as ultrasound-positive,” Guillaume Denis, MD, and colleagues explained. “Patients with no halo sign, or bilateral halo signs in the axillary arteries, or a unilateral halo sign in the temporal artery were considered as ultrasound-negative.”

The findings were published in Annals of Internal Medicine on May 7.
 

Results

In total, 73 participants (44%) had positive ultrasounds and were diagnosed with GCA. These patients also underwent a second ultrasound a month later to document if the halo sign remained unchanged, reduced, or disappeared.

The remaining 92 patients with negative ultrasound results underwent TAB, which was conducted on average 4.5 days after the ultrasound. A total of 28 patients (30%) had a positive TAB result. Physicians diagnosed 35 TAB-negative patients with GCA using clinical, imaging, and biologic data, and 29 patients received alternative diagnoses. These other diagnoses included polymyalgia rheumatica, infectious diseases, cancer, and other systemic inflammatory rheumatic diseases.

All patients diagnosed with GCA via ultrasound had their diagnoses reconfirmed at 1 month and for up to 2 years of follow-up.

“In summary, our study showed that the use of temporal artery ultrasound may be an efficient way to make the diagnosis of GCA in patients with high clinical suspicion and to reduce imaging costs and the need for biopsy, thereby limiting complications and the need for a surgeon,” the authors concluded.
 

Qualifications and Limitations

While over half of patients ultimately diagnosed with GCA were diagnosed using ultrasound, that percentage was “a bit lower than expected,” said Mark Matza, MD, MBA, the co-clinical director of rheumatology at Massachusetts General Hospital in Boston. By comparison, one systematic review calculated ultrasound’s pooled sensitivity at 88% and pooled specificity at 96% for the diagnosis of GCA.

“In this [current] study, 30% of patients who had negative ultrasound were then found to have positive biopsy, indicating that ultrasound missed a substantial portion of patients who were ultimately diagnosed with GCA,” he continued.

Ultrasound is “very operator dependent,” he added, and there has been “variability in test performance of ultrasound.”

The authors acknowledged that techniques for ultrasound of the temporal arteries have also evolved over the study period, and thus, findings may not have been consistent.

However, about one in four patients with GCA were diagnosed after having both negative ultrasound and TAB results.

“One of the things that this paper shows is that even the gold standard of temporal artery biopsy isn’t 100% either,” noted Minna Kohler, MD, who directs the rheumatology musculoskeletal ultrasound program at Massachusetts General Hospital. “That’s why clinically, there is an increasing emphasis on using multimodality imaging to assist in the diagnosis of GCA along with a physician’s clinical intuition,” she said.

New research by Thomas Münzel, MD, senior professor of cardiology at Johannes Gutenberg University Mainz in Mainz, Germany, and colleagues again emphasized the harmful effects of noise on the heart and blood vessels. An analysis of current epidemiologic data provided strong indications that transportation noise is closely related to cardiovascular and cerebrovascular diseases, according to a statement on the data analysis. The results were published in Circulation Research.

Morbidity and Mortality

Epidemiologic studies have shown that road, rail, or air traffic noise increases the risk for cardiovascular morbidity and mortality, with strong evidence for ischemic heart disease, heart failure, and stroke, according to the scientists. The World Health Organization reported that at least 1.6 million healthy life years are lost annually in Western Europe because of traffic-related noise. Nighttime traffic noise leads to sleep fragmentation and shortening, an increase in stress hormone levels, and increased oxidative stress in the vessels and brain. These factors could favor vascular (endothelial) dysfunction, inflammation, and hypertension, thereby increasing cardiovascular risk.

Consequences and Pathomechanisms

In the current publication, the authors provided an overview of epidemiologic research on the effects of transportation noise on cardiovascular risk factors and diseases, discussed mechanistic insights from the latest clinical and experimental studies, and proposed new risk markers to address noise-induced cardiovascular effects in the general population. An integrated analysis in the article demonstrated that for every 10 dB(A) increase, the risk for cardiovascular diseases such as heart attack, stroke, and heart failure significantly increases by 3.2%.

The authors also explained the possible effects of noise on changes in gene networks, epigenetic pathways, circadian rhythms, signal transmission along the neuronal-cardiovascular axis, oxidative stress, inflammation, and metabolism. Finally, current and future noise protection strategies are described, and the existing evidence on noise as a cardiovascular risk factor is discussed.

Confirmed Cardiovascular Risk Factor

“As an increasing proportion of the population is exposed to harmful traffic noise, efforts to reduce noise and laws for noise reduction are of great importance for future public health,” said Dr. Münzel. “It is also important for us that due to the strong evidence, traffic noise is finally recognized as a risk factor for cardiovascular diseases.”

Heart Attack Outcomes

Dr. Münzel and other researchers from Mainz have been studying the cardiovascular consequences of air pollution and traffic noise for several years. For example, they found that heart attacks in people and animals exposed to high noise levels earlier in life healed poorly. These results were published last year in Cardiovascular Research. According to the authors, the findings suggest that traffic noise may play a significant role in the development and course of coronary heart disease, such as after a heart attack.

The scientists initially found in animal experiments that exposure to aircraft noise for 4 days led to increased inflammation in the vessels. Compared with mice not exposed to aircraft noise, the noise-exposed animals showed an increase in free radicals; these animals exhibited a significant inflammatory response and had impaired vessel function.

The researchers explained that the experimental data showed aircraft noise alone triggers a proinflammatory transcription program that promotes the infiltration of immune cells into cardiovascular tissue in animals with acute myocardial infarction. They noted an increased infiltration of CD45+ cells into the vessels and heart, dominated by neutrophils in vessel tissue and Ly6Chigh monocytes in heart tissue. This infiltration creates a proinflammatory milieu that adversely affects the outcome after myocardial infarction by predisposing the heart tissue to greater ischemic damage and functional impairment. Exposure of animals to aircraft noise before induction of myocardial infarction by left anterior descending (LAD) coronary artery ligation impaired left ventricular function and increased infarct size after cardiac ischemia. In addition, noise exposure exacerbated infarct-induced endothelial dysfunction of peripheral vessels as early as 24 hours after LAD ligation.

Clinical Confirmation

These experimental results were confirmed by observations in the population-based Gutenberg Health Study. The researchers analyzed data from 100 patients with heart attack. The lead and senior authors of the study Michael Molitor, MD, and Philip Wenzel, MD, of the University of Mainz, explained, “From our studies, we have learned that exposure to aircraft noise before a heart attack significantly amplifies subsequent cardiovascular inflammation and exacerbates ischemic heart failure, which is favored by inflammation-promoting vascular conditioning. Our translational results show that people who have been exposed to noise in the past have a worse course if they experience a heart attack later in life.”

Study participants who had experienced a heart attack in their medical history had elevated levels of C-reactive protein if they had been exposed to aircraft noise in the past and subsequently developed noise annoyance reactions (0.305 vs 1.5; P = .0094). In addition, left ventricular ejection fraction in these patients after a heart attack was worse than that in patients with infarction without noise exposure in their medical history (62.5 vs 65.6; P = .0053).

The results suggest that measures to reduce environmental noise could help improve the clinical outcomes of heart attack patients, according to the authors.

Mental Health Effects

Traffic noise also may be associated with an increased risk for depression and anxiety disorders, as reported 2 years ago by the German Society for Psychosomatic Medicine and Medical Psychotherapy. Evolution has programmed the human organism to perceive noises as indicators of potential sources of danger — even during sleep. “Noise puts the body on alert,” explained Manfred E. Beutel, MD, director of the Clinic for Psychosomatic Medicine and Psychotherapy at the University of Mainz. As a result, the autonomic nervous system activates stress hormones such as adrenaline and cortisol, leading to an increase in heart rate and blood pressure. If noise becomes chronic, chronic diseases can develop. “Indeed, observational and experimental studies have shown that persistent noise annoyance promotes incident hypertension, cardiovascular diseases, and type 2 diabetes,” said Dr. Beutel.

Depression Risk Doubled

Among the negative effects of noise annoyance are also mental illnesses, as has become increasingly clear. “Noise annoyance disrupts daily activities and interferes with feelings and thoughts, sleep, and recovery,” said Dr. Beutel. The interruptions trigger negative emotional reactions such as anger, distress, exhaustion, flight impulses, and stress symptoms. “Such conditions promote the development of depression over time,” said Dr. Beutel. This observation was confirmed by the large-scale Gutenberg Health Study using the example of the Mainz population, which suffers to a large extent from noise annoyance because of the nearby Frankfurt Airport. “With increasing noise annoyance, the rates of depression and anxiety disorders steadily increased, until the risks eventually doubled with extreme annoyance,” said Dr. Beutel. Other studies point in the same direction. For example, a meta-analysis found a 12% increase in the risk for depression per 10-dB increase in noise. Another study found an association between nocturnal noise annoyance and the use of antidepressants.

Fine Particulate Matter

According to an evaluation of the Gutenberg Study, people perceive noise annoyance from aircraft noise as the most pronounced, followed by road, neighborhood, industrial, and railway noise. Noise occurs most frequently in urban areas that also produce air pollution such as fine particulate matter. “Fine particulate matter is also suspected of promoting anxiety and depression,” said Dr. Beutel, “because the small particles of fine particulate matter can enter the bloodstream and trigger inflammatory processes there, which in turn are closely related to depression.”

Noise occurs most frequently in urban areas that also produce air pollution such as fine particulate matter. “Fine particulate matter is also suspected of promoting anxiety and depression,” said Dr. Beutel, “because the small particles of fine particulate matter can enter the bloodstream and trigger inflammatory processes there, which in turn are closely related to depression.”

BERLIN — To date, mRNA vaccines have had their largest global presence in combating the COVID-19 pandemic. Intensive research is underway on many other potential applications for this vaccine technology, which suggests a promising future. Martina Prelog, MD, a pediatric and adolescent medicine specialist at the University Hospital of Würzburg in Germany, reported on the principles, research status, and perspectives for these vaccines at the 25th Travel and Health Forum of the Center for Travel Medicine in Berlin.

To understand the future, the immunologist first examined the past. “The induction of cellular and humoral immune responses by externally injected mRNA was discovered in the 1990s,” she said.
 

Instability Challenge

Significant hurdles in mRNA vaccinations included the instability of mRNA and the immune system’s ability to identify foreign mRNA as a threat and destroy mRNA fragments. “The breakthrough toward vaccination came through Dr. Katalin Karikó, who, along with Dr. Drew Weissman, both of the University of Pennsylvania School of Medicine, discovered in 2005 that modifications of mRNA (replacing the nucleoside uridine with pseudouridine) enable better stability of mRNA, reduced immunogenicity, and higher translational capacity at the ribosomes,” said Dr. Prelog.

With this discovery, the two researchers paved the way for the development of mRNA vaccines against COVID-19 and other diseases. They were awarded the Nobel Prize in medicine for their discovery last year.
 

Improved Scalability

“Since 2009, mRNA vaccines have been studied as a treatment option for cancer,” said Dr. Prelog. “Since 2012, they have been studied for the influenza virus and respiratory syncytial virus [RSV].” Consequently, several mRNA vaccines are currently in development or in approval studies. “The mRNA technology offers the advantage of quickly and flexibly responding to new variants of pathogens and the ability to scale up production when there is high demand for a particular vaccine.”

Different forms and designations of mRNA vaccines are used, depending on the application and desired effect, said Dr. Prelog.

In nucleoside-modified mRNA vaccines, modifications in the mRNA sequence enable the mRNA to remain in the body longer and to induce protein synthesis more effectively.

Lipid nanoparticle (LNP)–encapsulated mRNA vaccines protect the coding mRNA sequences against degradation by the body’s enzymes and facilitate the uptake of mRNA into cells, where it then triggers the production of the desired protein. In addition, LNPs are involved in cell stimulation and support the self-adjuvant effect of mRNA vaccines, thus eliminating the need for adjuvants.

Self-amplifying mRNA vaccines include a special mRNA that replicates itself in the cell and contains a sequence for RNA replicase, in addition to the coding sequence for the protein. This composition enables increased production of the target protein without the need for a high amount of external mRNA administration. Such vaccines could trigger a longer and stronger immune response because the immune system has more time to interact with the protein.
 

Cancer Immunotherapy

Dr. Prelog also discussed personalized vaccines for cancer immunotherapy. Personalized mRNA vaccines are tailored to the patient’s genetic characteristics and antigens. They could be used in cancer immunotherapy to activate the immune system selectively against tumor cells.

Multivalent mRNA vaccines contain mRNA that codes for multiple antigens rather than just one protein to generate an immune response. These vaccines could be particularly useful in fighting pathogens with variable or changing surface structures or in eliciting protection against multiple pathogens simultaneously.

The technology of mRNA-encoded antibodies involves introducing mRNA into the cell, which creates light and heavy chains of antibodies. This step leads to the formation of antibodies targeted against toxins (eg, diphtheria and tetanus), animal venoms, infectious agents, or tumor cells.
 

Genetic Engineering

Dr. Prelog also reviewed genetic engineering techniques. In regenerative therapy or protein replacement therapy, skin fibroblasts or other cells are transfected with mRNA to enable conversion into induced pluripotent stem cells. This approach avoids the risk for DNA integration into the genome and associated mutation risks.

Another approach is making post-transcriptional modifications through RNA interference. For example, RNA structures can be used to inhibit the translation of disease-causing proteins. This technique is currently being tested against HIV and tumors such as melanoma.

In addition, mRNA technologies can be combined with CRISPR/Cas9 technology (“gene scissors”) to influence the creation of gene products even more precisely. The advantage of this technique is that mRNA is only transiently expressed, thus preventing unwanted side effects. Furthermore, mRNA is translated directly in the cytoplasm, leading to a faster initiation of gene editing.

Of the numerous ongoing clinical mRNA vaccine studies, around 70% focus on infections, about 12% on cancer, and the rest on autoimmune diseases and neurodegenerative disorders, said Dr. Prelog.
 

Research in Infections

Research in the fields of infectious diseases and oncology is the most advanced: mRNA vaccines against influenza and RSV are already in advanced clinical trials, Dr. Prelog told this news organization.

“Conventional influenza vaccines contain immunogenic surface molecules against hemagglutinin and neuraminidase in various combinations of influenza strains A and B and are produced in egg or cell cultures,” she said. “This is a time-consuming manufacturing process that takes months and, particularly with the egg-based process, bears the risk of changing the vaccine strain.”

“Additionally, influenza viruses undergo antigenic shift and drift through recombination, thus requiring annual adjustments to the vaccines. Thus, these influenza vaccines often lose accuracy in targeting circulating seasonal influenza strains.”

Several mRNA vaccines being tested contain not only coding sequences against hemagglutinin and neuraminidase but also for structural proteins of influenza viruses. “These are more conserved and mutate less easily, meaning they could serve as the basis for universal pandemic influenza vaccines,” said Dr. Prelog.

An advantage of mRNA vaccines, she added, is the strong cellular immune response that they elicit. This response is intended to provide additional protection alongside specific antibodies. An mRNA vaccine with coding sequences for the pre-fusion protein of RSV is in phase 3 trials for approval for vaccination in patients aged 60 years and older. It shows high effectiveness even in older patients and those with comorbidities.
 

Elaborate Purification Process

Bacterial origin plasmid DNA is used to produce mRNA vaccines. The mRNA vaccines for COVID-19 raised concerns that production-related DNA residues could pose a safety risk and cause autoimmune diseases.

These vaccines “typically undergo a very elaborate purification process,” said Dr. Prelog. “This involves enzymatic digestion with DNase to fragment and deplete plasmid DNA, followed by purification using chromatography columns, so that no safety-relevant DNA fragments should remain afterward.”

Thus, the Paul-Ehrlich-Institut also pointed out the very small, fragmented plasmid DNA residues of bacterial origin in mRNA COVID-19 vaccines pose no risk, unlike residual DNA from animal cell culture might pose in other vaccines.
 

Prevention and Therapy

In addition to the numerous advantages of mRNA vaccines (such as rapid adaptability to new or mutated pathogens, scalability, rapid production capability, self-adjuvant effect, strong induction of cellular immune responses, and safety), there are also challenges in RNA technology as a preventive and therapeutic measure, according to Dr. Prelog.

“Stability and storability, as well as the costs of new vaccine developments, play a role, as do the long-term effects regarding the persistence of antibody and cellular responses,” she said. The COVID-19 mRNA vaccines, for example, showed a well-maintained cellular immune response despite a tendency toward a rapid decline in humoral immune response.

“The experience with COVID-19 mRNA vaccines and the new vaccine developments based on mRNA technology give hope for an efficient and safe preventive and therapeutic use, particularly in the fields of infectious diseases and oncology,” Dr. Prelog concluded.

Like it or not, artificial intelligence (AI) is coming to medicine. For many physicians — maybe you — it’s already here.

More than a third of physicians use AI in their practice. And the vast majority of healthcare companies — 94%, according to Morgan Stanley — use some kind of AI machine learning.

“It’s incumbent on physicians, as well as physicians in training, to become familiar with at least the basics [of AI],” said internist Matthew DeCamp, MD, PhD, an associate professor in the Center for Bioethics and Humanities at the University of Colorado Anschutz Medical Campus, Aurora, Colorado.

Understanding AI can help you leverage it safely and effectively — plus “make better-informed decisions about whether or not to use it in [your] practice,” Dr. DeCamp said.

“Frankly, the people who are deciding whether to implement algorithms in our day-to-day lives are oftentimes not physicians,” noted Ravi B. Parikh, MD, an assistant professor at the University of Pennsylvania and director of augmented and artificial intelligence at the Penn Center for Cancer Care Innovation, Philadelphia. Yet, physicians are most qualified to assess an AI tool’s usefulness in clinical practice.

That brings us to the best starting place for your AI education: Your own institution. Find out what AI tools your organization is implementing — and how you can influence them.

“Getting involved with our hospital data governance is the best way not only to learn practically what these AI tools do but also to influence the development process in positive ways,” Dr. Parikh said.

From there, consider the following resources to enhance your AI knowledge.
 

Get a Lay of the Land: Free Primers

Many clinical societies and interest groups have put out AI primers, an easy way to get a broad overview of the technology. The following were recommended or developed by the experts we spoke to, and all are free:

• The American Medical Association’s (AMA’s) framework for advancing healthcare AI lays out actionable guidance. Ask three key questions, the AMA recommends: Does it work? Does it work for my patients? Does it improve health outcomes?
• The Coalition for Health AI’s Blueprint for Trustworthy AI Implementation Guidance and Assurance for Healthcare provides a high-level summary of how to evaluate AI in healthcare, plus steps for implementing it. AI systems should be useful, safe, accountable, explainable, fair, and secure, the report asserted.
• The National Academy of Medicine’s draft code of conduct for AI in healthcare proposes core principles and commitments. These “reflect simple guideposts to guide and gauge behavior in a complex system and provide a starting point for real-time decision-making,” the report said.
• Health AI Partnership — a collaboration of Duke Health and Microsoft — outlines eight key decision points to consider at any stage of AI implementation, whether you’re still planning how to use it or you’ve started but want to improve it. The site also provides a breakdown of standards by regulatory agencies, organizations, and oversight bodies — so you can make sure your practices align with their guidance.

Make the Most of Conferences

Next time you’re at a conference, check the agenda for sessions on AI. “For someone who’s interested in this, I would be looking for content in my next national meeting because, undoubtedly, it’s going to be there,” said Dr. DeCamp. In a fast-moving field like AI, it’s a great way to get fresh, up-to-the-moment insights.

Available on Apple, Spotify, and YouTube, the pod is good for “someone who’s looking to see both where the field is going [and to hear] a retrospective on big-name papers,” said Dr. Parikh . Episodes run for about an hour.

To learn about the challenges of applying AI to biology: Listen to Daphne Koller, PhD, founder of AI-driven drug discovery and development company insitro. For insights on the potential of AI in medicine, tune into the one with Eric Horvitz, MD, PhD, Microsoft’s chief scientific officer.
 

Consider a Class

Look for courses that focus on AI applications in clinical practice rather than a deep dive into theory. (You need to understand how these tools will influence your work, not the intricacies of large language model development.) Be wary of corporate-funded training that centers on one product , which could present conflicts of interest, said Dr. DeCamp. See the chart for courses that meet these criteria.

A recent review of the Open Payments database found that, over the last 10 years, the evil forces of Big Pharma have paid doctors $12.1 billion dollars.

That’s a lot.

Of course, there are also quite a few doctors out there, and the word “paid” is kind of a misnomer. Yes, some people did get paid directly — cash for research, speaking engagements, teaching other docs — but a lot of the money was really spent on marketing. It may show that Dr. Jones was “paid” $200 one day, when in reality that was the cost of providing lunch to her, her five-person office staff, and the medical student following her around that afternoon.

In the last 10 years, I’ve accepted “payments” of one pizza and three iced coffees, so I guess I’m on there, too.

When you actually break it down, this comes out to a national average of (drum roll) $48 per doctor over 10 years.

Let’s face it, if your prescribing habits can be bought for $4.80 a year ... that’s pretty sad. They say everyone has their price, but hopefully it’s not that of a Happy Meal.

I understand the reasons for tracking this sort of thing. The system certainly can be — and has been — gamed for abuse. If one doctor is getting a ridiculous amount of money for doing nothing but writing scripts for Walletgouge-XR, that certainly needs to be known. Something is rotten in the state of Denmark (or wherever).

But the headline, especially when used in the lay media, makes it sound like all docs are on payola, and further erodes trust in the medical field. The fact that it works out to $4.80 per doctor each year is going to buried deeper in the article, by which time most readers will have moved on to see what Taylor Swift is up to.

Perhaps I’ve taken it to an extreme, but since the pizza (2014) I haven’t done lunch at my office. I still meet with reps, but they’re told now that I don’t do lunch, or bagels, or even iced coffee anymore. Tell me what I need to know about the new drug, but at this point in my career I’d rather have time. By not meeting a rep over lunch, or coffee, it adds 30-60 minutes to my day to use for reviewing tests, returning calls, and typing up notes. Those are things I’m going to have to do at some point, so I’d rather do them at my office and have the extra time at home, even if it’s just to do a jigsaw puzzle with my daughter.

That’s worth more than $4.80 per year.

There is no association between the SARS-CoV-2 vaccine and the risk for new-onset seizure, data from a new meta-analysis of six randomized, placebo-controlled clinical trials (RCTs) showed.

Results of the pooled analysis that included 63,500 individuals vaccinated with SARS-CoV-2 and 55,000 who received a placebo vaccine showed there was no significant difference between the two groups with respect to new-onset seizures at 28- or 43-day follow-up.

Regarding new-onset seizures in the general population, there was no statistically significant difference in risk for seizure incidence among vaccinated individuals vs placebo recipients, according to our meta-analysis, wrote the investigators, led by Ali Rafati, MD, MPH, Iran University of Medical Sciences in Tehran.

The findings were published online in JAMA Neurology.

Mixed Results

Results from previous research have been mixed regarding the link between the SARS-CoV-2 vaccination and new-onset seizures, with some showing an association.

To learn more about the possible association between the vaccines and new-onset seizures, the researchers conducted a literature review and identified six RCTs that measured adverse events following SARS-CoV-2 vaccinations (including messenger RNA, viral vector, and inactivated virus) vs placebo or other vaccines.

While five of the studies defined new-onset seizures according to the Medical Dictionary for Regulatory Activities, trial investigators in the sixth RCT assessed and determined new-onset seizures in participants.

Participants received two vaccinations 28 days apart in five RCTs and only one vaccine in the sixth trial.

The research team searched the data for new-onset seizure in the 28 days following one or both COVID vaccinations.

No Link Found

After comparing the incidence of new-onset seizure between the 63,500 vaccine (nine new-onset seizures, 0.014%) and 55,000 placebo recipients (one new-onset seizure, 0.002%), investigators found no significant difference between the two groups (odds ratio [OR], 2.70; 95% CI, 0.76-9.57; P = .12)

Investigators also sliced the data several ways to see if it would yield different results. When they analyzed data by vaccine platform (viral vector) and age group (children), they didn’t observe significant differences in new-onset data.

The researchers also searched for data beyond the month following the injection to encompass the entire blinded phase, so they analyzed the results of three RCTs that reported adverse events up to 162 days after the vaccine.

After pooling the results from the three studies, investigators found no statistical difference between the vaccine and placebo groups in terms of the new-onset seizure (OR, 2.31; 95% CI, 0.86%-3.23; P > .99)

Study limitations included the missing information on vaccine doses or risk factors for the development of seizures. Also, the RCTs included in the meta-analysis were conducted at different times, so the SARS-CoV-2 vaccines may have differed in their composition and efficacy.

“The global vaccination drive against SARS-CoV-2 has been a monumental effort in combating the pandemic. SARS-CoV-2 vaccinations that are now available appear safe and appropriate,” the authors wrote.

There were no study funding sources or disclosures reported.

DENVER — A retrospective analysis of pediatric patients with Lennox-Gastaut syndrome (LGS) suggests that the antiseizure medication cenobamate (SK Life Sciences) in combination with existing lines of therapy may be associated with fewer hospital in-patient days and emergency room visits. The conclusions were reached by comparing outcomes to patient historical data, though they were not analyzed statistically.

A Proof-of-Concept Study

In an interview, Karen Keough, MD, who presented the study during a poster session at the 2024 annual meeting of the American Academy of Neurology, conceded the key limitation was that the researchers were not able to perform statistical analysis due to the nature of the data. “It’s just showing trends. It’s proof of concept that cenobamate can be effective in one of the most refractory forms of epilepsy, which always includes focal seizures. That’s what led to the initial FDA indication, but we also know that this medication has a lot of promise and is probably going to be effective in other forms of epilepsy and probably in other seizure types,” said Dr. Keough, who is a neurologist at Pediatrix Child Neurology Consultants of Austin, Texas.

Although she has seen significant improvements in many patients, Dr. Keough reported that most patients become refractory again. “Unfortunately, honeymoons are probably real in cenobamate. Continuing to follow those patients as I do, since they’re my own patients, I have quite a few who had more than a year of seizure freedom, [but] their seizures are back, though not as bad as they were before cenobamate. I just can’t get them back to that 100% control category. I do have a few that are still in the 100% control category, but not very many,” she said.

She also presented a retrospective chart review of 36 LGS patients between the ages of 1 and 27 years at the American Epilepsy Society in December 2023, which showed that addition of cenobamate was associated with a reduction in seizure frequency in 85% of patients. “It was a profound number of patients who had long periods of seizure freedom,” she said.
 

A Promising Treatment Option

Dr. Keough is considering moving cenobamate up in the treatment sequence of new LGS patients. “I don’t use cenobamate first line in anyone because we have good first-line agents for simple epilepsy in Lennox-Gastaut, but I’m bringing out cenobamate pretty early in the course, because I do think it has superior efficacy compared with most other drugs that we have available. Most of my patients are very established and they’ve seen lots of other drugs. For many patients, there are only a couple of drugs left on the list that [they] have never tried, but we’re going to put cenobamate at the top of that. For my newer diagnoses, I’m going to bring it out much earlier,” she said, though other drugs such as clobazam (Onfi) would still rank ahead of cenobamate.

The study was drawn from records of the HealthVerity Marketplace Database, which includes more than 150 commercial, Medicare, and Medicaid payers. It included 76 patients aged 17 or under who took at least one antiseizure medication between May 2020 and December 2022, and who had filled at least two prescriptions of cenobamate and had 180 or more days of medical and pharmacy enrollment. The mean age was 13.4 years (5.3% 0-5 years, 15.8% 6-11 years, 78.9% 12-17 years), and 40.8% were female. Seizure types included absence (17.1%), focal (75.0%), and generalized tonic-clonic (86.8%). All patients had a history of intractable seizures, 80.3% had a history of status epilepticus, and 28.9% had a history of infantile seizures. A little more than one fourth (27.6%) of patients had commercial insurance. In the previous 90 days, 21.1% had had an emergency room visit or in-patient hospital stay.

Common antiseizure medications taken with cenobamate included cannabidiol (n = 14), clobazam (n = 8), and levetiracetam (n = 18).

During the cenobamate treatment period, patients had a lower incidence of epilepsy-related inpatient days per year (3.36 vs 3.94), epilepsy-related ER visits per year (0.66 vs 1.19), and likelihood of requiring a new line of epilepsy therapy (35.5% vs 100%).
 

‘Promising’ Results, but More Research Is Needed

The fact that cenobamate was used in combination with other therapies, plus the lack of a control group, makes it difficult to determine if cenobamate was actually responsible for the improvements, according to Nassim Zecavati, MD, who was asked for comment on the study. “I think the results are promising, but there’s obviously a need for a randomized, controlled trial to understand whether it was this medication or the combination of cenobamate with [other medications]. How do we know that this isn’t a compound effect, that it’s multifactorial, and a combination of multiple medications versus the cenobamate?” she said.

Still, she noted that LGS patients are highly vulnerable to hospital admissions and status epilepticus, making the parameters examined in the study valid and important. “I think that this drug likely has a role in the treatment of patients with LGS, particularly pediatric patients. I think we just need more data,” said Dr. Zecavati, who is director of Epilepsy at the Children’s Hospital of Richmond in Virginia and associate professor of Neurology at Virginia Commonwealth University.

During the cenobamate treatment period, patients had a lower incidence of epilepsy-related inpatient days per year (3.36 vs 3.94), epilepsy-related ER visits per year (0.66 vs 1.19), and likelihood of requiring a new line of epilepsy therapy (35.5% vs 100%).
 

‘Promising’ Results, but More Research Is Needed

The fact that cenobamate was used in combination with other therapies, plus the lack of a control group, makes it difficult to determine if cenobamate was actually responsible for the improvements, according to Nassim Zecavati, MD, who was asked for comment on the study. “I think the results are promising, but there’s obviously a need for a randomized, controlled trial to understand whether it was this medication or the combination of cenobamate with [other medications]. How do we know that this isn’t a compound effect, that it’s multifactorial, and a combination of multiple medications versus the cenobamate?” she said.

Still, she noted that LGS patients are highly vulnerable to hospital admissions and status epilepticus, making the parameters examined in the study valid and important. “I think that this drug likely has a role in the treatment of patients with LGS, particularly pediatric patients. I think we just need more data,” said Dr. Zecavati, who is director of Epilepsy at the Children’s Hospital of Richmond in Virginia and associate professor of Neurology at Virginia Commonwealth University.

A plastic surgeon broke federal law when he restricted patients from posting negative reviews by requiring them to sign nondisclosure agreements before they received care, a district judge has ruled.

Seattle-based surgeon Javad Sajan, MD, ran afoul of the Consumer Review Fairness Act (CRFA) by requiring more than 10,000 patients to sign the agreements, according to a recent decision by US District Judge Ricardo S. Martinez. The law protects consumers’ rights to post truthful reviews about businesses. 

Judge Martinez wrote that the terms of Dr. Sajan’s nondisclosure agreements “clearly include language prohibiting or restricting patients from posting negative reviews,” in violation of CRFA. Penalties for the offense will be determined at a September trial. 

This news organization contacted Dr. Sajan’s office and his attorney for comment but did not get a response. 

The decision is the latest development in an ongoing legal dispute between Dr. Sajan and the State of Washington over whether the surgeon’s efforts to limit negative online reviews were illegal. 

Beginning in 2017, Dr. Sajan and his practice, Allure Esthetic, introduced agreements that “forced” patients to contact the business directly if they had concerns rather than post a negative review, according to a 2022 lawsuit against Dr. Sajan filed by Washington Attorney General Robert Ferguson. 

“Online reviews are often the first stop when consumers are determining who to trust,” Mr. Ferguson said in a statement. “That’s especially critical when those services deal with a patient’s health and safety. We will take action against those who illegally stop Washingtonians from sharing reviews with the public.”

If patients posted negative reviews, the clinic, in some cases, threatened litigation, according to the complaint. In other cases, patients were allegedly offered money and free services in exchange for taking the reviews down. Patients who accepted cash or services were required to sign a second agreement forbidding them from posting future negative reviews and imposing a $250,000 penalty for failure to comply, according to court documents. 

In court documents, Dr. Sajan’s attorneys argued the agreements did not violate CRFA because patients had the opportunity to modify the language or decline signing them, which hundreds did. The CRFA requires Mr. Ferguson to prove that consumers lacked a meaningful opportunity to negotiate the terms, attorneys for Dr. Sajan argued in court records. 

But Judge Martinez wrote that the patients who declined to sign the agreements or changed the terms represented only a “tiny fraction” of the affected patients.

The agreement language restricts patients from speaking out by forcing dissatisfied patients to work with Allure until a resolution is reached, Judge Martinez noted in his decision. “At the very least, this would delay patients from posting such reviews and force patients to interact in some way with Allure, and it certainly appears to prohibit posting reviews until Allure agrees to some kind of favorable resolution.”
 

Surgeon Posted Fake Positive Reviews to Counteract Bad Reviews, AG Says

Employee accounts in court documents describe a physician fixated on reviews who went to great lengths to ensure positive reviews about his work outweighed the negative. 

Former employees said they were instructed to track down patients who left negative reviews and either “threaten” them to take the posts down or offer them “money” or other things, according to Mr. Ferguson’s lawsuit. If patients could not be identified, the practice would file a defamation lawsuit against the anonymous person who posted the review and use litigation to subpoena the website for the reviewer’s IP address in order to identify them, according to court documents. 

Employees testified they had regular meetings to review current negative reviews and discuss what steps they were taking to get them removed. At team meetings, in-house counsel would regularly present an Excel spreadsheet with updates on progress in getting patients to remove negative reviews, according to court documents. 

In addition to restricting negative reviews, Mr. Ferguson accuses Dr. Sajan of posting fake positive reviews and “buying” thousands of fake followers on social media. 

At Dr. Sajan’s direction, employees created Gmail accounts using stock photos for their profile pictures and used the accounts to post fake reviews of Allure Esthetic and Dr. Sajan, according to the complaint. The practice also used members of an online forum called BlackHatWorld.com to create fake email accounts and to post fake reviews, the attorney general alleges. Many of the fake positive reviews, including the fake Google reviews, still appear on online review sites today, the attorney general contends. 

Dr. Sajan and his practice also allegedly manipulated social media to appear more popular. Mr. Ferguson claims that Dr. Sajan instructed his former web designer to purchase 60,000 followers through a vendor on BlackHatWorld.com. Most of Dr. Sajan’s current Instagram followers are not real, according to Mr. Ferguson. 

The practice also used a social media bot tool to buy thousands of fake likes on Instagram, YouTube, and other social media, according to court documents. 

In addition, Dr. Sajan and his practice are accused of significantly altering “before and after” photos of patients and using fake email accounts to allow the clinic to take skincare rebates intended for patients.

All of these practices violated HIPAA, the state Consumer Protection Act (CPA) and the federal CRFA, according to Mr. Ferguson. 
 

Surgeon Claims Competitor Behind Allegations 

Attorneys for Dr. Sajan argue a competitor is behind the accusations and that other regulatory entities determined the practice did nothing wrong. 

The competitor, a Seattle-based plastic surgeon, filed numerous complaints about Dr. Sajan to the Washington Medical Commission (WMC), according to court documents. The medical commission reviewed the third agreement and closed its investigation, finding that if the allegations were true, “no violation of law occurred,” court records show. 

“Defendants relied upon this closing code from the WMC that the (non-disclosure) forms were lawful,” Dr. Sajan’s attorneys wrote in court documents.

The US Department of Health & Human Services Office for Civil Rights (OCR) also reviewed and audited Dr. Sajan’s use of the agreements, his attorneys noted. In a notice from OCR included in court exhibits, the agency wrote that all matters at issue have now been resolved through the practice’s voluntary compliance actions and that it was closing its investigation. 

Attorneys for Dr. Sajan accuse Mr. Ferguson and state investigators of withholding the full extent of the competitor’s involvement in their investigation and failing to identify the competitor in written discovery or any of its initial disclosures. Dr. Sajan and his team discovered that the competitor was a source of key information through public records requests, according to court documents. 

The remaining claims against Dr. Sajan will be addressed at trial, set for September 9, 2024.

New guidelines to manage peripheral neuropathy related to Sjögren disease have been developed by a multidisciplinary team of physicians from across medicine.

The guidelines will provide an evidence-based resource for the assessment, diagnosis, and treatment of various peripheral neuropathies related to the disorder.

Up until now, the field has been “haphazard and chaotic,” lead author George Sarka, MD, DrPH, MPH, director of the CME Committee for MemorialCare, Saddleback Medical Center, Laguna Hills, California, and member of the Sjögren Foundation PNS Guidelines Topic Review Group (TRG), told this news organization.

Dr. Sarka discussed the initiative at the American Academy of Neurology 2024 annual meeting.


 

Severe, Complex Illness

Sjögren disease is the second most common autoimmune rheumatic disorder after rheumatoid arthritis, affecting an estimated 4 million Americans. Women make up most of the patient population at a ratio of 9:1.

The condition typically affects the mucous membranes and moisture-secreting glands of the eyes and mouth, resulting in decreased tears and saliva. But peripheral nervous system (PNS) manifestations often precede these symptoms and can occur in up to 60% of Sjögren disease cases.

“Traditionally, Sjögren’s was looked at as a dry eye and dry mouth disease, but we realize now that it’s so much broader than that,” said Dr. Sarka. “It’s a severe, systemic, and complex illness that can affect any body organ or system, and the nervous system is frequently affected.”

PNS manifestations cause more than mere discomfort; they can lead to diagnostic and management challenges, costly treatments, and diminished quality of life.

Getting a proper diagnosis goes a long way toward improving the quality of life for these patients, Steven Mandel, MD, clinical professor of neurology at the Zucker School of Medicine at Hofstra-Northwell, adjunct clinical professor of medicine at NY Medical College, New York City, and member of the TRG, told this news organization.

The problem is, doctors don’t always think an autoimmune disorder is causing the symptoms, said Dr. Sarka. “There’s an old adage in neurology that if you don’t think about it, you’re going to miss it; you have to ask, and that’s what we’re trying to get people to do.”

The condition often accompanies other immune system disorders such as rheumatoid arthritis and lupus. But as patients are referred back and forth between ophthalmologists, rheumatologists, and neurologists, the condition is often missed. “It could be 4 or 5 years before a definitive diagnosis of Sjögren’s is made,” said Dr. Sarka.

He believes the education system is partly to blame. “Medical schools have been very deficient in teaching people about recognizing Sjögren disease.”

That leaves many physicians at a loss about “what to do with these patients when they walk in the door,” said Dr. Mandel. “They don’t know how to manage them; they don’t know how to diagnose them; and they don’t know how to treat them.”

Developing guidelines with multispecialty collaboration was “absolutely critical” in addressing this knowledge gap, Dr. Mandel added. That process involved “a very rigorous and transparent methodology so that it would be accepted by all the professionals involved in Sjögren’s,” he said.

The process took 3 years and involved amassing and grading the evidence, getting consensus from committee members, developing recommendations, and getting feedback and external review.
 

Scant Evidence

An early literature search revealed very little evidence on PNS manifestations in patients with Sjögren disease, so the guideline committee “leaned very heavily on expert opinion” to develop recommendations, Kathy Hammitt, MA, vice president of Medical and Scientific Affairs, Sjögren’s Foundation, told this news organization.

The literature search also showed different terms are used to describe PNS, “which is where the chaos comes in,” said Dr. Sarka.

Experts from different specialties worked together to define and align nomenclature used by various specialists. They developed definitions for seven PNS categories including mononeuropathy, large fiber neuropathy, small fiber neuropathy, demyelinating polyradiculoneuropathy, ganglionopathy, vasculitis neuropathy, and autoimmune nervous system neuropathy.

The guidelines pertaining to PNS manifestations encompass a spectrum of neurologic abnormalities, including cranial neuropathies (trigeminal neuropathy or acute facial neuropathy), polyneuropathies (large fiber neuropathy, small fiber neuropathy, demyelinating polyradiculoneuropathy, vasculitis neuropathy, or ganglionopathy), and autonomic nervous system (ANS) neuropathies (postural tachycardia, orthostatic hypotension, or autonomic dysfunction).
 

Key Steps

The guidelines address two key steps for each PNS manifestation — the workup and evaluation of patients with suspected ANS manifestation including standard evaluations, diagnostic tests, and treatment. The experts developed 31 best practices for diagnosis and workup and 20 treatment recommendations.

Initial assessment of potential ANS involvement includes asking patients about orthostatic postural lightheadedness and difficulties with digestion, urination, sweating, and sexual function.

Treatment of autoimmune diseases typically focuses on relieving symptoms and can include steroids, the anticonvulsant gabapentin, the monoclonal antibody rituximab, and intravenous immunoglobulin. “The type of neuropathy will mandate or suggest certain therapies over others,” said Dr. Sarka, adding that a patient can have more than one neuropathy.

Therapeutics for Sjögren disease is another example of an area that has been “very haphazard,” he added.

The guidelines are aimed not just at specialists but also at general practitioners who treat many of these patients. But Dr. Hammitt emphasized that neurologists can be “instrumental” in identifying Sjögren disease in patients with PNS symptoms.

“Our hope is that specialists — in this case, neurologists — will recognize the potential for this condition in their PNS patients and ensure referral to a rheumatologist or knowledgeable family practitioner to manage overall care.”

The committee will soon submit its manuscript to the AAN for publication.

“Once published, we will have a robust dissemination strategy to ensure that providers, patients, and policymakers are aware of, and use, this very valuable resource,” said Dr. Hammitt.

No conflicts of interest were reported.

The problem is, doctors don’t always think an autoimmune disorder is causing the symptoms, said Dr. Sarka. “There’s an old adage in neurology that if you don’t think about it, you’re going to miss it; you have to ask, and that’s what we’re trying to get people to do.”

The condition often accompanies other immune system disorders such as rheumatoid arthritis and lupus. But as patients are referred back and forth between ophthalmologists, rheumatologists, and neurologists, the condition is often missed. “It could be 4 or 5 years before a definitive diagnosis of Sjögren’s is made,” said Dr. Sarka.

He believes the education system is partly to blame. “Medical schools have been very deficient in teaching people about recognizing Sjögren disease.”

That leaves many physicians at a loss about “what to do with these patients when they walk in the door,” said Dr. Mandel. “They don’t know how to manage them; they don’t know how to diagnose them; and they don’t know how to treat them.”

Developing guidelines with multispecialty collaboration was “absolutely critical” in addressing this knowledge gap, Dr. Mandel added. That process involved “a very rigorous and transparent methodology so that it would be accepted by all the professionals involved in Sjögren’s,” he said.

The process took 3 years and involved amassing and grading the evidence, getting consensus from committee members, developing recommendations, and getting feedback and external review.
 

Scant Evidence

An early literature search revealed very little evidence on PNS manifestations in patients with Sjögren disease, so the guideline committee “leaned very heavily on expert opinion” to develop recommendations, Kathy Hammitt, MA, vice president of Medical and Scientific Affairs, Sjögren’s Foundation, told this news organization.

The literature search also showed different terms are used to describe PNS, “which is where the chaos comes in,” said Dr. Sarka.

Experts from different specialties worked together to define and align nomenclature used by various specialists. They developed definitions for seven PNS categories including mononeuropathy, large fiber neuropathy, small fiber neuropathy, demyelinating polyradiculoneuropathy, ganglionopathy, vasculitis neuropathy, and autoimmune nervous system neuropathy.

The guidelines pertaining to PNS manifestations encompass a spectrum of neurologic abnormalities, including cranial neuropathies (trigeminal neuropathy or acute facial neuropathy), polyneuropathies (large fiber neuropathy, small fiber neuropathy, demyelinating polyradiculoneuropathy, vasculitis neuropathy, or ganglionopathy), and autonomic nervous system (ANS) neuropathies (postural tachycardia, orthostatic hypotension, or autonomic dysfunction).
 

Key Steps

The guidelines address two key steps for each PNS manifestation — the workup and evaluation of patients with suspected ANS manifestation including standard evaluations, diagnostic tests, and treatment. The experts developed 31 best practices for diagnosis and workup and 20 treatment recommendations.

Initial assessment of potential ANS involvement includes asking patients about orthostatic postural lightheadedness and difficulties with digestion, urination, sweating, and sexual function.

Treatment of autoimmune diseases typically focuses on relieving symptoms and can include steroids, the anticonvulsant gabapentin, the monoclonal antibody rituximab, and intravenous immunoglobulin. “The type of neuropathy will mandate or suggest certain therapies over others,” said Dr. Sarka, adding that a patient can have more than one neuropathy.

Therapeutics for Sjögren disease is another example of an area that has been “very haphazard,” he added.

The guidelines are aimed not just at specialists but also at general practitioners who treat many of these patients. But Dr. Hammitt emphasized that neurologists can be “instrumental” in identifying Sjögren disease in patients with PNS symptoms.

“Our hope is that specialists — in this case, neurologists — will recognize the potential for this condition in their PNS patients and ensure referral to a rheumatologist or knowledgeable family practitioner to manage overall care.”

The committee will soon submit its manuscript to the AAN for publication.

“Once published, we will have a robust dissemination strategy to ensure that providers, patients, and policymakers are aware of, and use, this very valuable resource,” said Dr. Hammitt.

No conflicts of interest were reported.

As three federal agencies investigate how private equity ownership and consolidation of healthcare organizations affects patient care and costs, physicians are giving them an earful.

“Before I retired, I could already see the damage private equity was doing to hospitals and medical practices. Well-regarded physician groups were being bought and the respected doctors and staff forced out to squeeze out profit for the buyers. Hospital-based physicians were being hit especially hard,” wrote Rhonda Wright, MD, of Brookhaven, Georgia. 

“Now, the rot is setting in for emergency rooms. One in four ERs is now (under-)staffed by private equity firms. This is leading to longer wait times, deterioration in patient care, and higher bills,” Dr. Wright continued. “Private equity takeover of medicine must be stopped. All such deals should be strictly regulated and should be heavily scrutinized, if not barred altogether. Our health depends upon it!”

The federal government is accepting public comments like Dr. Wright’s through June 5 and has even set up a website (healthycompetition.gov) to make it easier to file complaints against health organizations possibly violating antitrust laws.

The US Department of Justice’s Antitrust Division, the Federal Trade Commission (FTC), and the Department of Health and Human Services want to hear from physicians and the public about how private equity firms’ investments in healthcare entities, such as hospitals, nursing homes, or specialty service providers, affect patients and healthcare workers. The investigation will also evaluate how market pricing, competition, and referral patterns change when practices and hospitals are acquired by health systems or insurers.

Maintaining competition in the provider and payer markets benefits healthcare workers through higher pay, while patients can access quality care at lower prices, the joint request for information said. However, consolidation and mergers — potentially driven by private equity’s entry into the market — can diminish these benefits.

Investigating private equity and consolidation in medicine is part of the Biden Administration’s focus on lowering medical and prescription drug costs and strengthening competition in healthcare. The FTC’s vote last week to ban noncompete agreements, which business groups have vowed to challenge in court, falls under the same initiative.

Alexandra Nicole Thran, MD, FACEP, president of the Vermont Chapter of the American College of Emergency Physicians, said that the private equity business model is problematic because it ties physicians’ wages to patient satisfaction and the number of patients they see per hour. 

A Connecticut primary care physician expressed similar sentiments. “Physicians are being forced into a system where corporations provide financial incentives and punitive policies to direct healthcare decisions towards a profitable aim,” said Eric Schwaber, MD. 

While a majority of comments criticized the role of private equity and consolidation, some reflected a more positive view. 

“Private equity helps make healthcare more efficient and effective. It brings needed operational and managerial expertise to allow for better patient care,” said Reenie Abraham, MD, an associate professor in the Department of Internal Medicine at University of Texas Southwestern Medical Center, Dallas. The University of Texas is facing a lawsuit involving the liability status of its physicians who work for a private equity-backed hospital partly owned by the university.

Several public comments point to the increasing market influence UnitedHealth Group (UHG) and other payers have obtained through recent acquisitions. Retired emergency room physician Scott Davis, MD, said that the “astronomical” rate of burnout among providers has been exacerbated by “the economic takeover of the healthcare system by…United Healthcare [and] private equity groups who put profits over anything else.”  

The healthcare conglomerate employs approximately 10% of active US physicians, including many through its subsidiary, Optum Health, which provides primary, urgent, and surgical care. UHG has also invested heavily in acquiring physician practices to advance its value-based care model.

“If a publicly traded private insurance or private equity company is interested in their short-term quarterly profits or stock price, there is little interest in the…effective management of chronic disease, other than that which fulfills a ‘value-based’ metric,” wrote Kenneth Dolkart, MD, FACP, clinical assistant professor at the Dartmouth Geisel School of Medicine in Hanover, New Hampshire. 

Sarah Ealy, a revenue cycle professional, commented that payers like UHG have outsized bargaining power when negotiating rates with providers. “In many states, United Healthcare and its subsidiaries pay a lower reimbursement rate than state Medicaid plans — these rates are nearly 50% of the breakeven per-visit rate that practices need to keep the lights on.”

Another comment ties the recent cyberattack on UHG-owned Change Healthcare to private equity ownership and “healthcare behemoths buying up practices and data.”

“The ramrodding of consolidation and private oversight with little to no barriers to foreign intrusions…is a testament to how ill prepared [the] US market is to private equity healthcare takeovers,” said SW Dermatology Practice LLC. 

The agencies request comments from all health market participants, including physicians, nurses, employers, administrators, and patients.
