A silent disorder is rising among older people worldwide, as millions unknowingly grapple with glaucoma, ophthalmologists warn.

It’s predicted that by 2050, the number of people with glaucoma will surge by more than 200%, highlighting an urgent need for heightened awareness, early detection, and advanced treatment strategies.

“That’s a lot of people with a blinding disease who don’t know they have it,” said Joel S. Schuman, MD, professor of ophthalmology and codirector of the Glaucoma Service at Wills Eye Hospital in Philadelphia. “Late in the disease, people may notice they’re tripping over the curb, or walking into things they didn’t see. It really is only in very advanced disease that people notice there’s anything wrong.”

Glaucoma is the second leading cause of blindness worldwide, affecting 3 million people in the United States, and yet half of those affected are unaware, according to the Centers for Disease Control and Prevention. 

Recent research at the University of Gothenburg in Sweden underscores glaucoma’s stealthy nature: Five percent of 560 70-year-olds had the disease, and half of those did not know they had it before they took part in the study. 

“Living with glaucoma, especially without realizing it, can be very isolating,” said Lena Havstam Johansson, a PhD student at the University of Gothenburg and a specialist nurse at Sahlgrenska University Hospital, who did the study. “It may lead people to stay at home to avoid the trouble.”

Once symptoms arise, some may notice patchy blind spots in their peripheral vision, and in their central vision in late stages.

While many people assume they are getting clumsier with age, Dr. Schuman said, they often have a condition that can be slowed with the right treatment. 

Though there are various types of the disease, about 9 in 10 people in the United States have primary open-angle glaucoma (POAG).  

It is most common among people over the age of 60, those with a family history of glaucoma, and people who have diabetes. It disproportionately affects Black people, who are six times more likely than are White people to have advanced vision loss from the disease. 

More than 120,000 people in the United States are blind from glaucoma, accounting for 9%-12% of all cases of blindness. Glaucoma treatments range from eye drops to laser treatments to surgery, all of which aim to reduce eye pressure. Some doctors will recommend oral medication along with eye drops.

“We have a lot of treatment options, and they work pretty well,” Dr. Schuman said. “But the first step is the person knowing they have glaucoma, and the second step is that person seeking care.

Rarer types of glaucoma include normal-tension glaucoma, which is more common among people of Japanese ancestry, and congenital glaucoma, which affects about 1 in 10,000 babies born in the United States.

The best way to ensure early detection and treatment is to get regular eye exams – every 2-4 years for adults under the age of 55, and annually thereafter, said Annie Wu, MD, clinical assistant professor of ophthalmology at the Kellogg Eye Center at the University of Michigan. 

The fact that glaucoma’s symptoms are slow to develop, coupled with a lack of access to eye specialists many Americans face, makes the disease even more dangerous. 

The University of Pennsylvania is among those trying to change that. The Philadelphia school has hosted free glaucoma screening programs for Black residents.  

There are a number of organizations that offer access to free glaucoma screening.

A diet high in ultraprocessed food (UPF), particularly artificial sweeteners, has been linked to increased depression risk, new data from the Nurses Health Study II (NHS II) suggest.

Nurses who consumed more than eight servings daily had about a 50% higher risk of developing depression than nurses who consumed four or fewer servings daily.

However, in a secondary analysis, in which the researchers tried to tease out specific foods that may be associated with increased risk, only artificial sweeteners and artificially sweetened beverages were associated with an increased risk of depression.

“Animal studies have shown that artificial sweeteners may trigger the transmission of particular signaling molecules in the brain that are important for mood,” study investigator Andrew T. Chan, MD, MPH, of the clinical and translational epidemiology unit at Massachusetts General Hospital, Boston, said in an interview.

“Given this potential association between ultraprocessed food and multiple adverse health conditions, wherever possible individuals may wish to limit their intake of such foods. This may be a lifestyle change that could have important benefits, particularly for those who struggle with mental health,” Dr. Chan said.

The study was published online in JAMA Network Open.
 

Multiple potential mechanisms

The findings are based on 31,712 mostly non-Hispanic White women who were free of depression at baseline. The mean age of the patients at baseline was 52 years. As part of the NHS II, the women provided information on diet every 4 years using validated food frequency questionnaires.

Compared with women with low UPF intake, those with high UPF intake had greater body mass index (BMI). In addition, they were apt to smoke and have diabetes, hypertension, and dyslipidemia, and they were less apt to exercise regularly.

During the study period, there were 2,122 incident cases of depression, as determined using a strict definition that required self-reported clinician-diagnosed depression and regular antidepressant use. There were 4,840 incident cases, as determined using a broad definition that required clinical diagnosis and/or antidepressant use.

Compared with women in the lowest quintile of UPF consumption (fewer than four daily servings), those in the highest quintile (more than 8.8 daily servings) had an increased risk of depression.

This was noted for both the strict depression definition (hazard ratio, 1.49; 95% confidence interval, 1.26-1.76; P < .001) and the broad one (HR, 1.34; 95% CI, 1.20-1.50; P < .001).

“Models were not materially altered after inclusion of potential confounders. We did not observe differential associations in subgroups defined by age, BMI, physical activity, or smoking,” the researchers reported.

In secondary analyses, they classified UPF into their components, including ultraprocessed grain foods, sweet snacks, ready-to-eat meals, fats, sauces, ultraprocessed dairy products, savory snacks, processed meat, beverages, and artificial sweeteners.

Comparing the highest with the lowest quintiles, only high intake of artificially sweetened beverages (HR, 1.37; 95% CI, 1.19-1.57; P < .001) and artificial sweeteners (HR, 1.26; 95% CI, 1.10-1.43; P < .001) was associated with greater risk of depression and after multivariable regression.

In an exploratory analysis, women who reduced their UPF intake by at least three servings per day were at lower risk of depression (strict definition: HR, 0.84; 95% CI, 0.71-0.99), compared with those with relatively stable intake in each 4-year period.

“Ultraprocessed foods have been associated with several different health outcomes which may reflect an effect on common pathways that underlie chronic conditions,” said Dr. Chan.

For example, UPF intake has been associated with chronic inflammation, which in turns leads to multiple potential adverse health effects, including depression, he explained.

There is also a link between UPF and disruption of the gut microbiome.

“This is an important potential mechanism linking ultraprocessed food to depression since there is emerging evidence that microbes in the gut have been linked with mood through their role in metabolizing and producing proteins that have activity in the brain,” Dr. Chan said.
 

Association, not causation

Several experts weighed in on the study results in a statement from the U.K. nonprofit organization, Science Media Centre.

Gunter Kuhnle, PhD, professor of nutrition and food science, University of Reading (England), cautioned that the study only offers information on association – not causation.

“It is very possible that people with depression change their diet and might decide to consume foods that are easier to prepare – which would often be foods considered to be ultraprocessed,” Dr. Kuhnle said.

What’s most interesting is that the association between UPF intake and depression was driven by a single factor – artificial sweeteners.

“This supports one of the main criticisms of the UPF concept, that it combines a wide range of different foods and thereby makes it difficult to identify underlying causes,” Dr. Kuhnle added.

“There are currently no data that link artificial sweetener use to mental health, despite most of them having been available for some time. It is also important to note that there are a wide range of different artificial sweeteners that are metabolized very differently and that there might be reverse causality,” Dr. Kuhnle commented.

Paul Keedwell, MBChB, PhD, consultant psychiatrist and fellow of the Royal College of Psychiatrists, said this is an “interesting and important finding, but one that raises more questions. At this stage, we cannot say how big an effect diet has on depression risk compared to other risk factors, like family history of depression, stress levels, and having a supportive social network.”

Dr. Keedwell noted that the investigators carefully excluded the possibility that the effect is mediated by obesity or lack of exercise.

“However, an important consideration is that a diet based on ready meals and artificially sweetened drinks might indicate a hectic lifestyle or one with shift work. In other words, a fast-food diet could be an indirect marker of chronic stress. Prolonged stress probably remains the main risk factor for depression,” Dr. Keedwell said.

Keith Frayn, PhD, professor emeritus of human metabolism, University of Oxford (England), noted that the relationship between artificial sweeteners and depression “stands out clearly” even after adjusting for multiple confounding factors, including BMI, smoking, and exercise.

“This adds to growing concerns about artificial sweeteners and cardiometabolic health. The link with depression needs confirmation and further research to suggest how it might be brought about,” Dr. Frayn cautioned.

The NHS II was funded by a grant from the National Cancer Institute. Dr. Chan reported receiving grants from Bayer and Zoe and personal fees from Boehringer Ingelheim, Pfizer, and Freenome outside this work. Dr. Keedwell and Dr. Kuhnle disclosed no relevant financial relationships. Dr. Frayn is an author of books on nutrition and metabolism.

MILAN – Numerous unresolved questions surround progressive pulmonary fibrosis (PPF) treatment, according to Elisabeth Bendstrup, MD, PhD, a researcher and clinical professor in the department of clinical medicine – department of respiratory diseases and allergy, Aarhus (Denmark) University, Denmark. These questions regard the optimal timing for treatment initiation, the role of available medications, either as monotherapy or in combination, and nonpharmacologic support options.

What’s in the toolbox?

Pulmonologists who manage PPF have a range of treatment options at their disposal. This includes careful patient observation, with treatment initiation based on clinical necessity. The therapeutic arsenal comprises immunomodulatory treatments, antifibrotic agents, palliative and supportive care, and, for a minority of patients, lung transplantation.

“Once a patient is diagnosed with PPF, it is important to remember that the diagnostic criteria from the guidelines are not exactly the same of those accepted for the reimbursement of antifibrotic treatments in different countries,” Dr. Bendstrup said, suggesting that nonclinical considerations could also potentially influence the treatment choice. She spoke at the annual congress of the European Respiratory Society.

Michael Kreuter, MD, director of the Lung Center at the University Hospital in Mainz, Germany, provided insight into the introduction of antifibrotic drugs for the treatment of PPF. Drawing from nearly a decade ago when the first antifibrotic medication was approved for idiopathic pulmonary fibrosis (IPF), Dr. Kreuter noted its effectiveness in slowing disease progression, although it does not reverse it. Subsequently, the discovery that non-IPF diseases, such as rheumatoid arthritis, exhibited IPF-like behavior led to the exploration of the use of the same drugs for similar conditions, even if not IPF.

“That’s how antifibrotic treatments came into place. Now we have more trials and data to be discussed in the future,” Dr. Kreuter added. He highlighted that antifibrotic drugs are effective for several diseases. Most of those diseases are treated with different anti-inflammatory drugs, which makes it difficult to decide when to start antifibrotic therapy and how to eventually combine it with different pharmacologic approaches.
 

A pivotal starting point

One of the primary challenges faced by pulmonologists in the management of PPF is determining the appropriate timing for initiating treatment, a question only partially addressed by existing guidelines. Dr. Bendstrup advocated for a comprehensive baseline evaluation. Factors to be considered include symptom burden, the severity of lung decline, radiologic characteristics, signs of alveolar inflammation, progression risk factors, quality of life, patient preferences, and medical history. “All these should be best discussed in a multidisciplinary team, including pulmonologists, nurses, experts in palliative care, occupational physicians, and more,” she said.

Current guidelines recommend nintedanib for PPF treatment for patients who have failed standard management for fibrotic interstitial lung disease (ILD) other than IPF. However, the definition of “standard management” remains a topic of debate, and it is acknowledged that evidence-based guidance for a standard of care varies among patients. Dr. Bendstrup pointed out the limited guidance clinicians receive from these guidelines. “As clinicians, we are not left with very much help from here.”
 

Choosing the right approach

Dr. Bendstrup delved into the factors influencing the choice between antifibrotic and anti-inflammatory therapies. This decision hinges on whether the patient presents with a predominantly inflammatory or a fibrotic progressive phenotype. Certain clinical characteristics contribute to the decision. Factors such as younger age, female gender, and the presence of connective tissue disease lean toward an inflammatory phenotype. Radiologic patterns, such as organized pneumonia, hypersensitivity pneumonia, or usual interstitial pneumonia–like patterns also provide valuable clues. Additionally, genetics plays a role, with shorter telomeres indicating a more fibrotic phenotype and an increased risk of immunomodulatory treatment side effects in non-IPF ILDs.

Bendstrup referred to a recent position paper on treatment recommendations and many other studies that support the use of different treatments for patients with PPF. The authors highlighted limited evidence for immunomodulation in fibrotic ILD, though such treatment is generally used except for ILD associated with systemic sclerosis. Moreover, the guidelines conditionally recommend nintedanib and call for further research on pirfenidone in PPF.

“We need intelligent, well-designed trials looking at subgroups of patients at higher risk, maybe based on molecular identification. We also need to have good biomarkers to better classify our patients based on disease behavior and treatment response. There’s a lot of discussion of biomarkers for progression, much less – if any – on biomarkers for the response to treatment. And we need them as well,” Dr. Bendstrup said in an interview.
 

The role of supportive care

Effective PPF treatment extends beyond pharmacologic interventions. It encompasses symptom management, patient education on vaccination and smoking cessation, and fostering social support networks. Psychological support, supplemental oxygen therapy, and pulmonary rehabilitation are integral components of care.

Elisabeth Robertson, a PPF patient representative from the United Kingdom, emphasized the importance of palliative care, not just in end-of-life scenarios but throughout the patient’s journey. Palliative care encompasses symptom alleviation, enabling patients to stay at home when possible, addressing mental health, and preparing for the end of life. Such holistic care can significantly enhance the patient’s quality of life.

The cochair of the session, Marlies S. Wijsenbeek, MD, PhD, pulmonary physician and head of the ILD Centre at the Erasmus University Medical Centre, Rotterdam, the Netherlands, underscored that palliative care begins at diagnosis and involves managing symptom burdens. “Supportive care also includes nurses, as they are precious for the patients while answering their questions and can help save time for the doctors,” she said in an interview.

In the discussion on treatment decisions, experts agreed on the pivotal role of patients in decision-making. However, Dr. Kreuter highlighted two critical factors that influence successful patient-doctor interactions: the cultural backgrounds of patients and their relatives, and the attitudes of health care providers.

MILAN – Numerous unresolved questions surround progressive pulmonary fibrosis (PPF) treatment, according to Elisabeth Bendstrup, MD, PhD, a researcher and clinical professor in the department of clinical medicine – department of respiratory diseases and allergy, Aarhus (Denmark) University, Denmark. These questions regard the optimal timing for treatment initiation, the role of available medications, either as monotherapy or in combination, and nonpharmacologic support options.

What’s in the toolbox?

Pulmonologists who manage PPF have a range of treatment options at their disposal. This includes careful patient observation, with treatment initiation based on clinical necessity. The therapeutic arsenal comprises immunomodulatory treatments, antifibrotic agents, palliative and supportive care, and, for a minority of patients, lung transplantation.

“Once a patient is diagnosed with PPF, it is important to remember that the diagnostic criteria from the guidelines are not exactly the same of those accepted for the reimbursement of antifibrotic treatments in different countries,” Dr. Bendstrup said, suggesting that nonclinical considerations could also potentially influence the treatment choice. She spoke at the annual congress of the European Respiratory Society.

Michael Kreuter, MD, director of the Lung Center at the University Hospital in Mainz, Germany, provided insight into the introduction of antifibrotic drugs for the treatment of PPF. Drawing from nearly a decade ago when the first antifibrotic medication was approved for idiopathic pulmonary fibrosis (IPF), Dr. Kreuter noted its effectiveness in slowing disease progression, although it does not reverse it. Subsequently, the discovery that non-IPF diseases, such as rheumatoid arthritis, exhibited IPF-like behavior led to the exploration of the use of the same drugs for similar conditions, even if not IPF.

“That’s how antifibrotic treatments came into place. Now we have more trials and data to be discussed in the future,” Dr. Kreuter added. He highlighted that antifibrotic drugs are effective for several diseases. Most of those diseases are treated with different anti-inflammatory drugs, which makes it difficult to decide when to start antifibrotic therapy and how to eventually combine it with different pharmacologic approaches.
 

A pivotal starting point

One of the primary challenges faced by pulmonologists in the management of PPF is determining the appropriate timing for initiating treatment, a question only partially addressed by existing guidelines. Dr. Bendstrup advocated for a comprehensive baseline evaluation. Factors to be considered include symptom burden, the severity of lung decline, radiologic characteristics, signs of alveolar inflammation, progression risk factors, quality of life, patient preferences, and medical history. “All these should be best discussed in a multidisciplinary team, including pulmonologists, nurses, experts in palliative care, occupational physicians, and more,” she said.

Current guidelines recommend nintedanib for PPF treatment for patients who have failed standard management for fibrotic interstitial lung disease (ILD) other than IPF. However, the definition of “standard management” remains a topic of debate, and it is acknowledged that evidence-based guidance for a standard of care varies among patients. Dr. Bendstrup pointed out the limited guidance clinicians receive from these guidelines. “As clinicians, we are not left with very much help from here.”
 

Choosing the right approach

Dr. Bendstrup delved into the factors influencing the choice between antifibrotic and anti-inflammatory therapies. This decision hinges on whether the patient presents with a predominantly inflammatory or a fibrotic progressive phenotype. Certain clinical characteristics contribute to the decision. Factors such as younger age, female gender, and the presence of connective tissue disease lean toward an inflammatory phenotype. Radiologic patterns, such as organized pneumonia, hypersensitivity pneumonia, or usual interstitial pneumonia–like patterns also provide valuable clues. Additionally, genetics plays a role, with shorter telomeres indicating a more fibrotic phenotype and an increased risk of immunomodulatory treatment side effects in non-IPF ILDs.

Bendstrup referred to a recent position paper on treatment recommendations and many other studies that support the use of different treatments for patients with PPF. The authors highlighted limited evidence for immunomodulation in fibrotic ILD, though such treatment is generally used except for ILD associated with systemic sclerosis. Moreover, the guidelines conditionally recommend nintedanib and call for further research on pirfenidone in PPF.

“We need intelligent, well-designed trials looking at subgroups of patients at higher risk, maybe based on molecular identification. We also need to have good biomarkers to better classify our patients based on disease behavior and treatment response. There’s a lot of discussion of biomarkers for progression, much less – if any – on biomarkers for the response to treatment. And we need them as well,” Dr. Bendstrup said in an interview.

Answering the protein question when prescribing plant-based diets

Cate Collings, MD

Science supports the use of a whole food, predominantly plant-based dietary pattern for optimal health, including reduced risk for chronic disease, and best practice in treatment of leading chronic disease.

But clinicians who prescribe such eating patterns encounter a common concern from patients whose health may benefit.

“Where will I get my protein?”

We’ve all heard it, and it’s understandable. Patients know that protein is essential for their health and strength, and animal foods have developed a reputation for being the premier protein sources that humans should prioritize through diet. But widespread misconceptions about human needs for protein have inaccurately equated animal food as the best and only sources of protein, augmented by fad diets and modern food marketing. All of this leads to confusion about how much protein people should actually consume and the quality of protein found in plant foods, making many patients reluctant to fully embrace a whole food.

To ensure that patients have all the facts when making dietary decisions, clinicians need to be prepared to respond to concerns about protein adequacy and quality with evidence-based information. A good starting point for these conversations is to assess how much protein patients are already consuming. A review of the 2015-2016 National Health and Nutrition Examination Survey found that women normally consume an average of 69 g and men an average of 97 g of protein daily.

As a general point of reference, the recommended dietary allowance for protein is about 0.8 g/kg of bodyweight (or 0.36 g/lb), which equates to about 52 g of protein per day for a 145-lb woman and 65 g for a 180-lb man. But for many patients, it may be best to get a more precise recommendation based upon age, gender and physical activity level by using a handy Department of Agriculture tool for health care professionals to calculate daily protein and other nutrient needs. Patients can also use one of countless apps to track their protein and other nutrient intake. By using the tool and a tracking app, both clinician and patients can be fully informed whether protein needs are being met.

Continuous glucose monitors for pregnant patients?

Robert Fulton

Patients with pregestational diabetes may benefit from use of a continuous subcutaneous insulin infusion pump paired with a continuous glucose monitor. Use of the tools has been associated with a reduction in maternal and neonatal morbidity, a recent study found.

“We were seeing an unacceptable burden of both maternal and fetal disease in our diabetic population,” said Neil Hamill, MD, a maternal-fetal medicine specialist at Methodist Women’s Hospital, Omaha, Neb., and an author of the study. “We thought the success with this technology in the nonpregnant population would and should translate into the pregnant population.”

Dr. Hamill and his colleagues analyzed data from 55 pregnant patients who received care at the Women’s Hospital Perinatal Center at the Nebraska Methodist Health System between October 2019 and October 2022. Everyone in the cohort had pregestational diabetes and required insulin prior to week 20 of pregnancy. They used CGMs for more than 2 weeks. The study set blood glucose levels of less than 140 mg/dL as a healthy benchmark.

Participants who had severe preeclampsia, who had delivered preterm, who had delivered a neonate with respiratory distress syndrome, and/or who had given birth to a larger-than-expected infant spent less time in the safe zone — having a blood glucose level below 140 mg/dL—than women who did not have those risk factors.

“When blood sugar control is better, maternal and fetal outcomes are improved,” Dr. Hamill said.

Neetu Sodhi, MD, an ob.gyn. at Providence Cedars-Sinai Tarzana Medical Center, Los Angeles, expressed optimism that use of blood glucose monitors and insulin pumps can improve outcomes for pregnant patients with pregestational diabetes.

“This is just another case for why it’s so important for patients to have access to these types of devices that really, really improve their outcomes and their health, and now it’s proven in the case of pregnancy outcomes too – or at least suggested strongly with this data,” Dr. Sodhi said.

It may be time to pay attention to COVID again

Kara Grant; Damian McNamara, MA

More than 3 years into the COVID-19 era, most Americans have settled back into their prepandemic lifestyles. But a new dominant variant and rising hospitalization numbers may give way to another summer surge.

Since April, a new COVID variant has cropped up. According to recent Centers for Disease Control and Prevention data, EG.5—from the Omicron family—now makes up 17% of all cases in the United States, up from 7.5% in the first week of July.

A summary from the Center for Infectious Disease Research and Policy at the University of Minnesota says that EG.5, nicknamed “Eris” by health trackers, is nearly the same as its parent strain, XBB.1.9.2, but has one extra spike mutation.

Along with the news of EG.5’s growing prevalence, COVID-related hospitalization rates have increased by 12.5% during the week ending on July 29—the most significant uptick since December. Still, no connection has been made between the new variant and rising hospital admissions. And so far, experts have found no difference in the severity of illness or symptoms between Eris and the strains that came before it.

Cause for concern?

The COVID virus has a great tendency to mutate, said William Schaffner, MD, a professor of infectious diseases at Vanderbilt University, Nashville, Tenn.

“Fortunately, these are relatively minor mutations.” Even so, SARS-CoV-2, the virus that causes COVID-19, continues to be highly contagious. “There isn’t any doubt that it’s spreading—but it’s not more serious.”

So, Dr. Schaffner doesn’t think it’s time to panic. He prefers calling it an “uptick” in cases instead of a “surge,” because a surge “sounds too big.”

While the numbers are still low, compared with 2022’s summer surge, experts still urge people to stay aware of changes in the virus. “I do not think that there is any cause for alarm,” agreed Bernard Camins, MD, an infectious disease specialist at Mount Sinai Hospital, New York.

So why the higher number of cases? “There has been an increase in COVID cases this summer, probably related to travel, socializing, and dwindling masking,” said Anne Liu, MD, an allergy, immunology, and infectious disease specialist at Stanford (Calif.) University. Even so, “because of an existing level of immunity from vaccination and prior infections, it has been limited and case severity has been lower than in prior surges.” ●

TOPLINE:

Men exposed to either job-related stress or an imbalance between the effort they put in and the rewards they reap at work have a 50% increased risk for coronary heart disease (CHD), and those facing both stressors have double the risk compared with colleagues not suffering from these stressors, new research shows. Results in women were inconclusive, suggesting a more complex relationship of these factors, the researchers noted.

METHODOLOGY:

• Evidence suggests psychosocial stressors at work, from job strain related to level of demand and control in workload and decision-making responsibilities, and an effort-reward imbalance (ERI) in areas such as salary, promotion, and job stability, increase CHD risk, with the effect of both types of stressors together possibly being especially harmful.
• The study, which included 6,465 participants in the cardiovascular component of PROQ, a Canadian prospective cohort of white-collar workers initially free of cardiovascular disease, mean age 45 years, estimated that the separate and combined effect of job strain and ERI on CHD incidence.
• Researchers used the Job Content Questionnaire to assess psychological demands and job control; various measures; scales to determine job strain, reward, and effort at work; and the sum of both effort and reward to calculate the ERI ratio.
• They assessed CHD using medico-administrative databases and an algorithm validated by medical records.

TAKEAWAY:

• After a median follow-up of 18.7 years, there were 571 and 265 incident CHD cases among men and women, respectively.
• Men with either job strain or ERI had a 49% increased risk for CHD (hazard ratio [HR], 1.49; 95% confidence interval [CI], 1.07-2.09), an estimate comparable to that of several lifestyle risk factors for CHD.
• Male workers facing both job strain and ERI had a 103% increased risk for CHD (HR, 2.03; 95% CI, 1.38-2.97), which is comparable to the increased risk associated with obesity.
• Associations were robust to adjustments for demographic, socioeconomic, psychosocial, personality, stressful life events, and biomedical and lifestyle factors.
• Among women, results were inconclusive because the CIs were wide enough to encompass both protective and detrimental effects, suggesting more research is needed into the complex interplay of various stressors and women’s heart health.

IN PRACTICE:

“Integrative and interdisciplinary approaches should be used to tackle psychosocial stressors at work,” the authors wrote, adding this involves “going beyond traditional modifiable individual behaviors” and should include “population-based prevention strategies taking into consideration both the individual and their work environment.”

TOPLINE:

Men exposed to either job-related stress or an imbalance between the effort they put in and the rewards they reap at work have a 50% increased risk for coronary heart disease (CHD), and those facing both stressors have double the risk compared with colleagues not suffering from these stressors, new research shows. Results in women were inconclusive, suggesting a more complex relationship of these factors, the researchers noted.

METHODOLOGY:

• Evidence suggests psychosocial stressors at work, from job strain related to level of demand and control in workload and decision-making responsibilities, and an effort-reward imbalance (ERI) in areas such as salary, promotion, and job stability, increase CHD risk, with the effect of both types of stressors together possibly being especially harmful.

A nationwide dearth of the specialists known as classical hematologists (CHs), who are trained to treat noncancerous bleeding disorders, has left many patients stranded and health care systems struggling to cope.

Over decades, the shrinking pool of CHs – who are compensated far less than hematologist-oncologists – has put patients at risk without access to adequate and timely care. To alleviate this crisis, individual doctors and national organizations are taking action and making more resources available to CHs and their patients.
 

`Vicious cycle’

The root cause of the CH shortage can be traced to a dramatic reduction in the number of physicians trained in this field, as Leonard Valentino, MD, President of the National Bleeding Disorders Foundation in New York, explained in an interview.

“There is a vicious cycle where there’s not enough classical hematologists to be program directors, and therefore trainees are often steered to fellowships in oncology,” said Dr. Valentino.

According to data published in JAMA, in 1995 there were 74 classical hematology programs in the United States; by 2018, there were only 2, During this same time period, the number of combined hematology/oncology training programs (HOPs) nearly doubled, from 75 to 146. However, it is estimated that less than 5% of graduates of adult HOPs pursued a career in classical hematology, as reported in Blood Advances. This low percentage can be attributed, at least in part, to the emphasis that most HOPs place on oncology.

Dr. Valentino noted that financial pressures are also diverting medical students from becoming CHs, adding that a hematologist-oncologist can make three times the annual salary of a CH.

Furthermore, when CHs treat bleeding and clotting disorders, they often need to meet with a patient for a 60- to 90-minute initial consultation, then they go on to provide a lifetime of labor-intensive care.

“This work is neither verticalized [that is, supported by radiologists, surgeons, and a cadre of nurses], nor is it billable per hour on a scale comparable to what oncologists can charge,” Dr. Valentino explained.

The survey published in Blood Advances illustrates the consequences of such a disparity in income potential: 34% of hematology/oncology fellows surveyed were likely to enter solid tumor oncology, while 20% and 4.6% would proceed to malignant hematology and CH, respectively.
 

Toll on patients

Primary care doctors treat some common blood disorders, but they almost always refer more difficult or complicated cases to a shrinking population of CHs.

Dr. Mukul Singal

“For many Americans, it is getting more difficult to find providers who subspecialize in hemostasis and thrombosis disorders. Patients can expect prolonged waiting times to get evaluated after a referral” said Mukul Singal, MD, of the Indiana Hemophilia and Thrombosis Center in Indianapolis.

Dr. Singal said the shortage is so acute that “at many institutions, malignant hematologists or oncologists are having to staff in-patient hematology consult services and see outpatient classical hematology patients. General hematologist/oncologists or medical oncologists are often not as comfortable or experienced with dealing with some of the complex CH conditions.”
 

A working care model, without enough doctors

In 1975, responding to patient advocacy groups, the federal government began funding hemophilia treatment centers (HTCs). Such centers offer a comprehensive care model that gives patients access to practitioners and administrative staff with the expertise to help them stay as healthy as possible. According to the Centers for Disease Control and Prevention, people with hemophilia who used an HTC were 40% less likely to die of a hemophilia-related complication and 40% less likely to be hospitalized for bleeding complications, compared to those who did not receive such specialized care.

“HTCs are effective at keeping patients out of the hospital and engaged in their lives. Between 80% and 95% of hemophilia patients get their care from an HTC and more patients want more services from them,” said Joe Pugliese, president of the Hemophilia Alliance in Lansdale, Pa.

Expanding care to meet patient demand is challenged by the restrictions on doctors’ salaries. All 140 U.S.-based HTCs share a $4.9 million federal grant but, by law, they can’t pay any provider more than $211,000 a year. “These restrictions push many people to industry, leaving too few doctors to meet patient demand,” Mr. Pugliese explained.

The fact that most HTCs are located in or near major cities also presents patients with the challenge of commuting, sometimes across state lines, to see a specialist. However, an uptick in telemedicine has provided one bright spot for many patients, allowing care to be brought to them.

The Hemophilia Alliance is also working on a multifaceted approach to change the rules, so that CHs are offered better compensation. “We have lobbyists in Washington, as well as an advocacy committee and a payer committee working to better support the HTC model,” Mr. Pugliese said.
 

Beyond the paycheck: Supporting CHs and patients

As market and regulatory restrictions make it difficult to boost the pay of CHs, doctors and nonprofit organizations are collaborating to support young CHs and bring more into the field. The American Society of Hematology has started and fully funded the Hematology Focused Fellowship Training Program (HFFTP). This program pairs comprehensive classical hematology training with education in transfusion medicine, sickle cell disease, hemostasis/thrombosis, systems-based hematology, health equity research, and global health. According to the program’s website, HFFTP’s goal is to add 50 new academic hematologists nationwide by 2030, in an effort to “improve the lives of patients with blood and bone marrow disorders.”

Additionally, classic hematologists are aiming to attract younger physicians and trainees to their field by introducing them to the various rewarding aspects of dealing with patients with inherited, chronic blood diseases. Programs like the Partners Physicians Academy (PPA), a 5-day training course that is specifically designed to encourage and retain young hematology students as classical hematologists, are essential to this effort.

“Along with preparing physicians to work in an HTC, programs like the Hematology Focused Fellowship Training Program and the Partners Physicians Academy are so important because they might convince young doctors to stick with non–oncology-based hematology careers, through the right mix of knowing about exciting research like gene therapy, financial and mentorship support, and a desire to meet unmet medical need,” explained Dr. Valentino.

The next PPA is taking place Sept. 18-22 in Indianapolis.

Dr. Singal, Dr. Valentino, and Mr. Pugliese had no financial disclosures to report.

The 2022-2023 Term of the Supreme Court illustrates how important the Court has become to health-related matters, including decisions regarding the selection and training of new professionals, the daily practice of medicine, and the future availability of new drugs. The importance of several cases is reinforced by the fact that major medical organizations filed amicus curiae (“friend of the court”) briefs in those cases.

Amicus briefs are filed by individuals or organizations with something significant to say about a case to the court—most often to present a point of view, make an argument, or provide information that the parties to the case may not have communicated. Amicus briefs are burdensome in terms of the time, energy, and cost of preparing and filing. Thus, they are not undertaken lightly. Medical organizations submitted amicus briefs in the first 3 cases we consider.

Admissions, race, and diversity

The case: Students for Fair Admissions v President and Fellows of Harvard College

The American College of Obstetricians and Gynecologists (ACOG) joined an amici curiae brief in Students for Fair Admissions v President and Fellows of Harvard College (and the University of North Carolina [UNC]).¹ This case challenged the use of racial preferences in college admissions. The Association of American Medical Colleges (AAMC) was the lead organization; nearly 40 other health-related organizations joined the brief.

The legal claim. Those filing the suits asserted that racial preferences by public colleges violate the 14th Amendment’s Equal Protection Clause (“no state shall deny to any person … the equal protection of the law”). That is, if a state university gives racial preferences in selective admissions, it denies some other applicant the equal protection of the law. As for private schools (in this case, Harvard), Title VI of the Civil Rights Act of 1964 has the same standards as the Equal Protection Clause. Thus, the Court consolidated the cases and used the same legal standard in considering public and private colleges (with “colleges” including professional and graduate programs as well as undergraduate institutions).

Background. For nearly 50 years, the Supreme Court has allowed limited racial preferences in college admissions. Those preferences could only operate as a plus, however, and not a negative for applicants and be narrowly tailored. The measure was instituted temporarily; in a 2003 case, the Court said, “We expect that 25 years from now, the use of racial preferences will no longer be necessary.”²

Decision. In a 6-3 decision, the Court held (in the UNC case) that racial preferences generally violate the Constitution, and by a 6-2 decision (in the Harvard case) these preferences violate the Civil Rights Act of 1964. (Justice Jackson was recused in the Harvard case because of a conflict.) The opinion covered 237 pages in the US Reports, so any summary is incomplete.

The majority concluded, “The Harvard and UNC admissions programs cannot be reconciled with the guarantees of the Equal Protection Clause. Both programs lack sufficiently focused and measurable objectives warranting the use of race, unavoidably employ race in a negative manner, involve racial stereotyping, and lack meaningful end points. We have never permitted admissions programs to work in that way, and we will not do so today.”³

There were 3 concurring opinions and 2 dissents in the case. The concurrences reviewed the history of the Equal Protection Clause and the Civil Rights Act, the damage racial preferences can do, and the explicit limits the Court said there must be on racial preferences in higher education. The dissents had a different view of the legal history of the 14th Amendment. They said the majority was turning a blind eye to segregation in society and the race-based gap in America.

As a practical matter, this case means that colleges, including professional schools, cannot use racial preferences. The Court said that universities may consider essays and the like in which applicants describe how their own experiences as an individual (including race) have affected their own lives. However, the Court cautioned that “universities may not simply establish through application essays or other means the regime we hold unlawful today.”³

The amici brief

ACOG joined 40 other health-related organizations in filing an amici brief (multiple “friends”) in Students for Fair Admission. The AAMC led the brief, with the others signing as amici.⁴ The brief made 3 essential points: diversity in medical education “markedly improves health outcomes,” and a loss of diversity “threaten[s] patients’ health; medical schools engage in an intense “holistic” review of applicants for admission; and medical schools must consider applicants’ “full background” (including race) to achieve their educational and professional goals.⁴

A powerful part of the brief described the medical school admissions process, particularly the very “holistic” review that is not entirely dependent on admissions scores. The brief effectively weaves the consideration of race into this process, mentioning race (on page 22) only after discussing many other admissions factors.

Child custody decisions related to the Indian Child Welfare Act

The case: Haaland v Brackeen

The American Medical Association (AMA) and the American Academy of Pediatrics filed a brief in Haaland v Brackeen⁵ involving the constitutionality of the 1978 Indian Child Welfare Act (ICWA). The statute followed a terrible history of Indian children being removed from their families inappropriately, as detailed in a concurring opinion by Justice Gorsuch.⁵ The two purposes of the act were to promote raising Native American children in their culture and stem the downward trend in tribal membership.

The legal claim. The Court consolidated several cases. Essentially, a 10-month-old child (A.L.M.) was placed in foster care with the Brackeens in Texas. After more than 1 year, the Brackeens sought adoption; the biological father, mother, and grandparents all supported it. The Navajo and Cherokee Nations objected and informed the Texas court that they had found alternative placement with (nonrelative) tribal members in New Mexico. The “court-appointed guardian and a psychological expert … described the strong emotional bond between A.L.M. and his foster parents.” The court denied the adoption petition based on ICWA’s preference for tribe custody, and the Brackeens filed a lawsuit. The Court noted that the act “requires a state court to place an Indian child with an Indian caretaker, if one is available, even if the child is already living with a non-Indian family and the state court thinks it in the child’s best interest to stay there.” That is, the ICWA may require a placement that the court believes is not in the child’s best interest.⁵

Decision. The constitutional claim in the case was that Congress lacked the authority to impose these substantial rules on states in making child custody decisions. The Supreme Court, in a 7-2 decision, upheld the constitutionality of the ICWA. The Court found the authority primarily in Article 1, Section 8, giving Congress the power to “regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes.” In addition, the Court suggested that the treaty power and “principles inherent in the Constitution’s structure may empower Congress to act in the field of Indian affairs.”

The amici brief

The joint amici brief of the American Academy of Pediatrics (AAP) and the AMA argued that tribes are “extended families” of Native American children.⁶ It noted the destructive history of removing Native American children from their families and suggested that kinship care improves children’s health. To its credit, the brief also honestly noted the serious mental health and suicide rates in some tribes, which suggest issues that might arise in child custody and adoption cases.

The Court did not, in this case, take up another constitutional issue that the parties raised—whether the strong preference for Native American over non ̶ Native American custody violates the Equal Protection Clause of the 14th Amendment. The Court said the parties to this case did not have standing to raise the issue. Justice Kavanaugh, concurring, said it was a “serious” issue and invited it to be raised in another case.⁵

False Claims Act cases

The case: Costs for SuperValu prescriptions

For physicians and health care organizations, False Claims Act (FCA) cases are an ongoing burden and, some would say, threat. (There are also state FCAs, but here we are discussing the federal act.) The federal government has recovered more than $70 billion since 1986, most from health care entities.⁷ The Justice Department identifies “health care fraud” as the largest area of FCA recovery and provides annual details on frauds resulting in liability.⁸

The legal claim. One FCA case this Term involved billings SuperValu made for outpatient prescriptions in Medicare-Medicaid programs. As its “usual and customary” costs, it essentially reported a list price that did not include the substantial discounts it commonly gave.⁹ The charge was that it “knowingly” made a false claim regarding the price of prescriptions. The question was what state of mind, or “scienter,” is required for “knowingly.” Should it be objective (what a reasonable person would know) or subjective (the defendant’s “knowledge and subjective beliefs”)?

Background. Subjective knowledge (what the defendant actually knows) may seem impossible to prove—the defendant could just say, “I did not know I was doing wrong.” Over time the law has developed several ways of demonstrating “knowing.” Justice Thomas, writing for a unanimous Court, held that whistleblowers or the government might prove “knowing” in 3 ways:

1. defendants “actually knew that their reported prices were not their ‘usual and customary’ prices when they reported them”

2. were aware of a substantial risk that their higher, retail prices were not their “usual and customary” prices and intentionally avoided learning whether their reports were accurate

3. were aware of such a substantial and unjustifiable risk but submitted the claims anyway.⁹

Of course, records of the company, information from the whistleblower, and circumstantial evidence may be used to prove any of these; it does not require the company’s admission.

The Court said that if the government or whistleblowers make a showing of any of these 3 things, it is enough.

Decision. The case was returned to the lower court to apply these rules.

The amici brief

The American Hospital Association and America’s Health Insurance Plans filed an amici brief.¹⁰ It reminded the Court that many reimbursement regulations are unclear. Therefore, it is inappropriate to impose FCA liability for guessing incorrectly what the regulations mean. Having to check on every possible ambiguity was unworkable. The Court declined, however, the suggestion that defendants should be able to use any one of many “objectively” reasonable interpretations of regulations.

Continue to: The case: Polansky v Executive Health Resources...

The case: Polansky v Executive Health Resources

Health care providers who dislike the FCA may find solace this Term in this second FCA case.¹¹

The legal claim. Polansky, a physician employed by a medical billing company, became an “intervenor” in a suit claiming the company assisted hospitals in false billing (inpatient claims for outpatient services). The government sought to dismiss the case, but Polansky refused.

Decision. The case eventually reached the Supreme Court, which held that the government may enter an FCA case at any time and move to dismiss the case even over the objection of a whistleblower. The government does not seek to enter a case in order to file dismissal motions often. When it does so, whistleblowers are protected by the fact that the dismissal motion requires a hearing before the federal court.

An important part of this case has escaped much attention. Justices Thomas, Kavanaugh, and Barrett invited litigation to determine if allowing private whistleblowers to represent the government’s interest is consistent with Article II of the Constitution.¹¹ The invitation will likely be accepted. We expect to see cases challenging the place of “intervenors” pursuing claims when the government has declined to take up the case. The private intervenor is a crucial provision of the current FCA, and if such a challenge were successful, it could substantially reduce FCA cases.

Criminal false claims

Another case this Term is cautionary about the consequences of health care misbilling. It resulted in a criminal charge. More importantly, in addition to a basic fraud charge, the government added a charge of aggravated identity theft,¹² which carries a mandatory 2-year prison sentence.

Dubin overbilled Medicaid for psychological testing by saying the testing was done by a licensed psychologist rather than an assistant. The government claimed the “identity theft” was using the patient’s (actual) Medicaid number in submitting the bill.¹² The Court unanimously held the overbilling was not aggravated identity theft as defined in federal law. Dubin could be convicted of fraudulent billing but not aggravated identity theft, thereby avoiding the mandatory prison term.

Patents of “genus” targets

The case: Amgen v Sanofi

This case, which corrected an error of the patent office, received little attention but was likely a turning point in the next generation of pharmaceuticals.¹³

Background. “Genus” patents allow a single pharmaceutical company to patent every antibody that binds to a specific amino acid on a naturally occurring protein. In this case, the patent office had granted a “genus” patent on “all antibodies” that bind to the naturally occurring protein PCSK9 and block it from hindering the body’s mechanism for removing low-density lipoprotein (LDL) cholesterol from the bloodstream,¹³ helping to reduce LDL cholesterol levels. These patents could involve millions of antibodies—and Amgen was claiming a patent on all of them. Amgen and Sanofi marketed their products, each with their own unique amino acid sequence.¹³ Amgen sued Sanofi for violating its patent rights.

Decision. The Court unanimously held that Amgen did not have a valid patent on all antibodies targeting PCSK9, only those that it had explicitly described in its patent application—a ruling based on a 150-year-old technical requirement for receiving a patent. An applicant for a patent must include “a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art…to make and use the same.”¹³ Amgen’s patent provided the description for only a few of the antibodies, but from the description in its application others could not “make and use” all of the antibodies targeting PCSK9.

While the decision was vital for future pharmaceuticals, the patent principle on which it was based has an interesting history. The Court noted that it affected the telegraph (Morse lost part of his patent), electric lights (Edison won his case against other inventors), and the glue for wood veneering (Perkins Glue Company lost).¹³

Other notable decisions

Student loans

The Court struck down the Biden Administration’s student loan forgiveness program, which would have cost approximately $430 billion.¹⁴ The central issue was whether the administration had the authority for such massive loan forgiveness; that is, whether Congress had authorized the broad loan forgiveness. The administration claimed authority from the post ̶ 9/11 HEROES Act, which allows the Secretary of Education to “waive or modify” loan provisions during national emergencies. The temporary hold on loan payments during COVID was based on this provision. However, in a 6-3 decision, the Court held that the act did not allow the secretary to cancel $430 billion in loans. “The Act allows the Secretary to ‘waive or modify’ existing statutory or regulatory provisions applicable to financial assistance programs under the Education Act, not to rewrite that statute from the ground up.”¹⁴

Free speech and the wedding web designer

303 Creative v Elenis involved a creative website designer who did not want to be required to create a website for a gay wedding.¹⁵ The designer had strong beliefs against same-sex marriages, but Colorado sought to force her to do so under the state “public accommodations” law. In a 6-3 decision, the Court held that the designer had a “free speech” right. That is, the state could not compel her to undertake speech expressing things she did not believe. This was because the website design was an expressive, creative activity and therefore was “speech” under the First Amendment.

Wetlands and the Clean Water Act

The essential issue in Sackett v Environmental Protection Agency (EPA) was the definitions of waters of the United States and related wetlands. The broad definition the EPA used meant it had jurisdiction to regulate an extraordinary amount of territory. It had, for example, prevented the Sacketts from building a modest house claiming it was part of the “waters of the United States because they were near a ditch that fed into a creek, which fed into Priest Lake, a navigable, intrastate lake.” The Court held that the EPA exceeded its statutory authority to define “wetlands.”¹⁶

The Court held that under the Clean Water Act, for the EPA to establish jurisdiction over adjacent wetlands, it must demonstrate that¹⁶:

1. “the adjacent body of water constitutes waters of the United States (ie, a relatively permanent body of water connected to traditional interstate navigable waters)…”

2. “…the wetland has a continuous surface connection with that water, making it difficult to determine where the water ends, and the wetland begins.”

Under this definition, the Sacketts could build their house. This was a statutory interpretation case. Therefore, Congress can expand or otherwise change the EPA’s authority under the Clean Water Act and other legislation.

Conclusions: A new justice, “shadow docket,” and ethics rules

SCOTUS’ newest member. When the Marshall called the Court into session on October 3, 2022, it had a new member, Justice Ketanji Brown Jackson. She was sworn in on June 30, 2022, when her predecessor (Justice Breyer) officially retired. She had been a law clerk for Justice Breyer in 1999, as well as a district court judge and court of appeals judge. Those who count such things described her as the “chattiest justice.”¹⁷ She spoke more than any other justice—by one count, a total of 75,632 words (an average of 1,300 words in each of the 58 arguments).

A more balanced Court? Most commentators view the Court as more balanced or less conservative than the previous Term. For example, Justice Sotomayor was in the majority 40% last Term but 65% this Term. Justice Thomas was in the majority 75% last Term but 55% this Term. Put another way, this Term in the divided cases, the liberal justices were in the majority 64% of the time, compared with the conservative justices 73%.¹⁸ Of course, these differences may reflect a different set of cases rather than a change in the direction of the Court. There were 11 (or 12, depending on how 1 case is counted) 6-3 cases, but only 5 were considered ideological. That suggests that, in many cases, the coalitions were somewhat fluid.

“Shadow docket” controversy continues.¹⁹ Shadow docket refers to orders the Court makes that do not follow oral arguments and often do not have written opinions. The orders are all publicly available. This Term a close examination of the approximately 30 shadow docket opinions shows that the overwhelming majority were dissents or explanations about denials of certiorari. The Court ordered only a few stays or injunctions via the shadow docket. One shadow docket stay (that prevented a lower court order from going into effect) is particularly noteworthy. A federal judge had ordered the suspension of the distribution of mifepristone while courts considered claims that the US Food and Drug Administration (FDA) had improperly approved the drug. In a shadow docket order, the Court issued the stay to allow mifepristone to be sold while the case challenging its approval was heard.²⁰ The only opinion was a dissent from Justice Alito. But it also demonstrates the importance of the shadow docket. Without this intervention, in at least part of the country, the distribution of mifepristone would have been interrupted pending the outcome of the FDA cases.

In August, the Court delayed a settlement in the Purdue Pharma liability bankruptcy case.²¹ It also stayed an injunction of a lower court, thereby permitting federal “ghost guns” regulations to go into effect at least temporarily.²²

More ethics rules to come? Another area in which the Court faced criticism was formal ethics rules. The justices make financial disclosures, but these are somewhat ambiguous. There is likely to be increasing pressure for a more complete disclosure of non-financial relationships and more formal ethics rules. ●

The 2022-2023 Term of the Supreme Court illustrates how important the Court has become to health-related matters, including decisions regarding the selection and training of new professionals, the daily practice of medicine, and the future availability of new drugs. The importance of several cases is reinforced by the fact that major medical organizations filed amicus curiae (“friend of the court”) briefs in those cases.

Amicus briefs are filed by individuals or organizations with something significant to say about a case to the court—most often to present a point of view, make an argument, or provide information that the parties to the case may not have communicated. Amicus briefs are burdensome in terms of the time, energy, and cost of preparing and filing. Thus, they are not undertaken lightly. Medical organizations submitted amicus briefs in the first 3 cases we consider.

Admissions, race, and diversity

The case: Students for Fair Admissions v President and Fellows of Harvard College

The American College of Obstetricians and Gynecologists (ACOG) joined an amici curiae brief in Students for Fair Admissions v President and Fellows of Harvard College (and the University of North Carolina [UNC]).¹ This case challenged the use of racial preferences in college admissions. The Association of American Medical Colleges (AAMC) was the lead organization; nearly 40 other health-related organizations joined the brief.

The legal claim. Those filing the suits asserted that racial preferences by public colleges violate the 14th Amendment’s Equal Protection Clause (“no state shall deny to any person … the equal protection of the law”). That is, if a state university gives racial preferences in selective admissions, it denies some other applicant the equal protection of the law. As for private schools (in this case, Harvard), Title VI of the Civil Rights Act of 1964 has the same standards as the Equal Protection Clause. Thus, the Court consolidated the cases and used the same legal standard in considering public and private colleges (with “colleges” including professional and graduate programs as well as undergraduate institutions).

Background. For nearly 50 years, the Supreme Court has allowed limited racial preferences in college admissions. Those preferences could only operate as a plus, however, and not a negative for applicants and be narrowly tailored. The measure was instituted temporarily; in a 2003 case, the Court said, “We expect that 25 years from now, the use of racial preferences will no longer be necessary.”²

Decision. In a 6-3 decision, the Court held (in the UNC case) that racial preferences generally violate the Constitution, and by a 6-2 decision (in the Harvard case) these preferences violate the Civil Rights Act of 1964. (Justice Jackson was recused in the Harvard case because of a conflict.) The opinion covered 237 pages in the US Reports, so any summary is incomplete.

The majority concluded, “The Harvard and UNC admissions programs cannot be reconciled with the guarantees of the Equal Protection Clause. Both programs lack sufficiently focused and measurable objectives warranting the use of race, unavoidably employ race in a negative manner, involve racial stereotyping, and lack meaningful end points. We have never permitted admissions programs to work in that way, and we will not do so today.”³

There were 3 concurring opinions and 2 dissents in the case. The concurrences reviewed the history of the Equal Protection Clause and the Civil Rights Act, the damage racial preferences can do, and the explicit limits the Court said there must be on racial preferences in higher education. The dissents had a different view of the legal history of the 14th Amendment. They said the majority was turning a blind eye to segregation in society and the race-based gap in America.

As a practical matter, this case means that colleges, including professional schools, cannot use racial preferences. The Court said that universities may consider essays and the like in which applicants describe how their own experiences as an individual (including race) have affected their own lives. However, the Court cautioned that “universities may not simply establish through application essays or other means the regime we hold unlawful today.”³

The amici brief

ACOG joined 40 other health-related organizations in filing an amici brief (multiple “friends”) in Students for Fair Admission. The AAMC led the brief, with the others signing as amici.⁴ The brief made 3 essential points: diversity in medical education “markedly improves health outcomes,” and a loss of diversity “threaten[s] patients’ health; medical schools engage in an intense “holistic” review of applicants for admission; and medical schools must consider applicants’ “full background” (including race) to achieve their educational and professional goals.⁴

A powerful part of the brief described the medical school admissions process, particularly the very “holistic” review that is not entirely dependent on admissions scores. The brief effectively weaves the consideration of race into this process, mentioning race (on page 22) only after discussing many other admissions factors.

Child custody decisions related to the Indian Child Welfare Act

The case: Haaland v Brackeen

The American Medical Association (AMA) and the American Academy of Pediatrics filed a brief in Haaland v Brackeen⁵ involving the constitutionality of the 1978 Indian Child Welfare Act (ICWA). The statute followed a terrible history of Indian children being removed from their families inappropriately, as detailed in a concurring opinion by Justice Gorsuch.⁵ The two purposes of the act were to promote raising Native American children in their culture and stem the downward trend in tribal membership.

The legal claim. The Court consolidated several cases. Essentially, a 10-month-old child (A.L.M.) was placed in foster care with the Brackeens in Texas. After more than 1 year, the Brackeens sought adoption; the biological father, mother, and grandparents all supported it. The Navajo and Cherokee Nations objected and informed the Texas court that they had found alternative placement with (nonrelative) tribal members in New Mexico. The “court-appointed guardian and a psychological expert … described the strong emotional bond between A.L.M. and his foster parents.” The court denied the adoption petition based on ICWA’s preference for tribe custody, and the Brackeens filed a lawsuit. The Court noted that the act “requires a state court to place an Indian child with an Indian caretaker, if one is available, even if the child is already living with a non-Indian family and the state court thinks it in the child’s best interest to stay there.” That is, the ICWA may require a placement that the court believes is not in the child’s best interest.⁵

Decision. The constitutional claim in the case was that Congress lacked the authority to impose these substantial rules on states in making child custody decisions. The Supreme Court, in a 7-2 decision, upheld the constitutionality of the ICWA. The Court found the authority primarily in Article 1, Section 8, giving Congress the power to “regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes.” In addition, the Court suggested that the treaty power and “principles inherent in the Constitution’s structure may empower Congress to act in the field of Indian affairs.”

The amici brief

The joint amici brief of the American Academy of Pediatrics (AAP) and the AMA argued that tribes are “extended families” of Native American children.⁶ It noted the destructive history of removing Native American children from their families and suggested that kinship care improves children’s health. To its credit, the brief also honestly noted the serious mental health and suicide rates in some tribes, which suggest issues that might arise in child custody and adoption cases.

The Court did not, in this case, take up another constitutional issue that the parties raised—whether the strong preference for Native American over non ̶ Native American custody violates the Equal Protection Clause of the 14th Amendment. The Court said the parties to this case did not have standing to raise the issue. Justice Kavanaugh, concurring, said it was a “serious” issue and invited it to be raised in another case.⁵

False Claims Act cases

The case: Costs for SuperValu prescriptions

For physicians and health care organizations, False Claims Act (FCA) cases are an ongoing burden and, some would say, threat. (There are also state FCAs, but here we are discussing the federal act.) The federal government has recovered more than $70 billion since 1986, most from health care entities.⁷ The Justice Department identifies “health care fraud” as the largest area of FCA recovery and provides annual details on frauds resulting in liability.⁸

The legal claim. One FCA case this Term involved billings SuperValu made for outpatient prescriptions in Medicare-Medicaid programs. As its “usual and customary” costs, it essentially reported a list price that did not include the substantial discounts it commonly gave.⁹ The charge was that it “knowingly” made a false claim regarding the price of prescriptions. The question was what state of mind, or “scienter,” is required for “knowingly.” Should it be objective (what a reasonable person would know) or subjective (the defendant’s “knowledge and subjective beliefs”)?

Background. Subjective knowledge (what the defendant actually knows) may seem impossible to prove—the defendant could just say, “I did not know I was doing wrong.” Over time the law has developed several ways of demonstrating “knowing.” Justice Thomas, writing for a unanimous Court, held that whistleblowers or the government might prove “knowing” in 3 ways:

2. were aware of a substantial risk that their higher, retail prices were not their “usual and customary” prices and intentionally avoided learning whether their reports were accurate

3. were aware of such a substantial and unjustifiable risk but submitted the claims anyway.⁹

Of course, records of the company, information from the whistleblower, and circumstantial evidence may be used to prove any of these; it does not require the company’s admission.

The Court said that if the government or whistleblowers make a showing of any of these 3 things, it is enough.

Decision. The case was returned to the lower court to apply these rules.

The amici brief

The American Hospital Association and America’s Health Insurance Plans filed an amici brief.¹⁰ It reminded the Court that many reimbursement regulations are unclear.

The Court declined, however, the suggestion that defendants should be able to use any one of many “objectively” reasonable interpretations of regulations.

The case: Polansky v Executive Health Resources

Health care providers who dislike the FCA may find solace this Term in this second FCA case.¹¹

The legal claim. Polansky, a physician employed by a medical billing company, became an “intervenor” in a suit claiming the company assisted hospitals in false billing (inpatient claims for outpatient services). The government sought to dismiss the case, but Polansky refused.

Decision. The case eventually reached the Supreme Court, which held that the government may enter an FCA case at any time and move to dismiss the case even over the objection of a whistleblower. The government does not seek to enter a case in order to file dismissal motions often. When it does so, whistleblowers are protected by the fact that the dismissal motion requires a hearing before the federal court.

An important part of this case has escaped much attention. Justices Thomas, Kavanaugh, and Barrett invited litigation to determine if allowing private whistleblowers to represent the government’s interest is consistent with Article II of the Constitution.¹¹ The invitation will likely be accepted. We expect to see cases challenging the place of “intervenors” pursuing claims when the government has declined to take up the case. The private intervenor is a crucial provision of the current FCA, and if such a challenge were successful, it could substantially reduce FCA cases.

Criminal false claims

Another case this Term is cautionary about the consequences of health care misbilling. It resulted in a criminal charge. More importantly, in addition to a basic fraud charge, the government added a charge of aggravated identity theft,¹² which carries a mandatory 2-year prison sentence.

Dubin overbilled Medicaid for psychological testing by saying the testing was done by a licensed psychologist rather than an assistant. The government claimed the “identity theft” was using the patient’s (actual) Medicaid number in submitting the bill.¹² The Court unanimously held the overbilling was not aggravated identity theft as defined in federal law. Dubin could be convicted of fraudulent billing but not aggravated identity theft, thereby avoiding the mandatory prison term.

Patents of “genus” targets

This case, which corrected an error of the patent office, received little attention but was likely a turning point in the next generation of pharmaceuticals.¹³

In this case, the patent office had granted a “genus” patent on “all antibodies” that bind to the naturally occurring protein PCSK9 and block it from hindering the body’s mechanism for removing low-density lipoprotein (LDL) cholesterol from the bloodstream,¹³ helping to reduce LDL cholesterol levels.

While the decision was vital for future pharmaceuticals, the patent principle on which it was based has an interesting history. The Court noted that it affected the telegraph (Morse lost part of his patent), electric lights (Edison won his case against other inventors), and the glue for wood veneering (Perkins Glue Company lost).¹³

Free speech and the wedding web designer

303 Creative v Elenis involved a creative website designer who did not want to be required to create a website for a gay wedding.¹⁵ The designer had strong beliefs against same-sex marriages, but Colorado sought to force her to do so under the state “public accommodations” law. In a 6-3 decision, the Court held that the designer had a “free speech” right. That is, the state could not compel her to undertake speech expressing things she did not believe. This was because the website design was an expressive, creative activity and therefore was “speech” under the First Amendment.

Wetlands and the Clean Water Act

The essential issue in Sackett v Environmental Protection Agency (EPA) was the definitions of waters of the United States and related wetlands. The broad definition the EPA used meant it had jurisdiction to regulate an extraordinary amount of territory. It had, for example, prevented the Sacketts from building a modest house claiming it was part of the “waters of the United States because they were near a ditch that fed into a creek, which fed into Priest Lake, a navigable, intrastate lake.” The Court held that the EPA exceeded its statutory authority to define “wetlands.”¹⁶

The Court held that under the Clean Water Act, for the EPA to establish jurisdiction over adjacent wetlands, it must demonstrate that¹⁶:

1. “the adjacent body of water constitutes waters of the United States (ie, a relatively permanent body of water connected to traditional interstate navigable waters)…”

2. “…the wetland has a continuous surface connection with that water, making it difficult to determine where the water ends, and the wetland begins.”

Under this definition, the Sacketts could build their house. This was a statutory interpretation case. Therefore, Congress can expand or otherwise change the EPA’s authority under the Clean Water Act and other legislation.

Conclusions: A new justice, “shadow docket,” and ethics rules

SCOTUS’ newest member. When the Marshall called the Court into session on October 3, 2022, it had a new member, Justice Ketanji Brown Jackson.

Admissions, race, and diversity

The case: Students for Fair Admissions v President and Fellows of Harvard College

The American College of Obstetricians and Gynecologists (ACOG) joined an amici curiae brief in Students for Fair Admissions v President and Fellows of Harvard College (and the University of North Carolina [UNC]).¹ This case challenged the use of racial preferences in college admissions. The Association of American Medical Colleges (AAMC) was the lead organization; nearly 40 other health-related organizations joined the brief.

The legal claim. Those filing the suits asserted that racial preferences by public colleges violate the 14th Amendment’s Equal Protection Clause (“no state shall deny to any person … the equal protection of the law”). That is, if a state university gives racial preferences in selective admissions, it denies some other applicant the equal protection of the law. As for private schools (in this case, Harvard), Title VI of the Civil Rights Act of 1964 has the same standards as the Equal Protection Clause. Thus, the Court consolidated the cases and used the same legal standard in considering public and private colleges (with “colleges” including professional and graduate programs as well as undergraduate institutions).

Background. For nearly 50 years, the Supreme Court has allowed limited racial preferences in college admissions. Those preferences could only operate as a plus, however, and not a negative for applicants and be narrowly tailored. The measure was instituted temporarily; in a 2003 case, the Court said, “We expect that 25 years from now, the use of racial preferences will no longer be necessary.”²

Decision. In a 6-3 decision, the Court held (in the UNC case) that racial preferences generally violate the Constitution, and by a 6-2 decision (in the Harvard case) these preferences violate the Civil Rights Act of 1964. (Justice Jackson was recused in the Harvard case because of a conflict.) The opinion covered 237 pages in the US Reports, so any summary is incomplete.

The majority concluded, “The Harvard and UNC admissions programs cannot be reconciled with the guarantees of the Equal Protection Clause. Both programs lack sufficiently focused and measurable objectives warranting the use of race, unavoidably employ race in a negative manner, involve racial stereotyping, and lack meaningful end points. We have never permitted admissions programs to work in that way, and we will not do so today.”³

There were 3 concurring opinions and 2 dissents in the case. The concurrences reviewed the history of the Equal Protection Clause and the Civil Rights Act, the damage racial preferences can do, and the explicit limits the Court said there must be on racial preferences in higher education. The dissents had a different view of the legal history of the 14th Amendment. They said the majority was turning a blind eye to segregation in society and the race-based gap in America.

As a practical matter, this case means that colleges, including professional schools, cannot use racial preferences. The Court said that universities may consider essays and the like in which applicants describe how their own experiences as an individual (including race) have affected their own lives. However, the Court cautioned that “universities may not simply establish through application essays or other means the regime we hold unlawful today.”³

The amici brief

ACOG joined 40 other health-related organizations in filing an amici brief (multiple “friends”) in Students for Fair Admission. The AAMC led the brief, with the others signing as amici.⁴ The brief made 3 essential points: diversity in medical education “markedly improves health outcomes,” and a loss of diversity “threaten[s] patients’ health; medical schools engage in an intense “holistic” review of applicants for admission; and medical schools must consider applicants’ “full background” (including race) to achieve their educational and professional goals.⁴

A powerful part of the brief described the medical school admissions process, particularly the very “holistic” review that is not entirely dependent on admissions scores. The brief effectively weaves the consideration of race into this process, mentioning race (on page 22) only after discussing many other admissions factors.

Child custody decisions related to the Indian Child Welfare Act

The case: Haaland v Brackeen

The American Medical Association (AMA) and the American Academy of Pediatrics filed a brief in Haaland v Brackeen⁵ involving the constitutionality of the 1978 Indian Child Welfare Act (ICWA). The statute followed a terrible history of Indian children being removed from their families inappropriately, as detailed in a concurring opinion by Justice Gorsuch.⁵ The two purposes of the act were to promote raising Native American children in their culture and stem the downward trend in tribal membership.

The legal claim. The Court consolidated several cases. Essentially, a 10-month-old child (A.L.M.) was placed in foster care with the Brackeens in Texas. After more than 1 year, the Brackeens sought adoption; the biological father, mother, and grandparents all supported it. The Navajo and Cherokee Nations objected and informed the Texas court that they had found alternative placement with (nonrelative) tribal members in New Mexico. The “court-appointed guardian and a psychological expert … described the strong emotional bond between A.L.M. and his foster parents.” The court denied the adoption petition based on ICWA’s preference for tribe custody, and the Brackeens filed a lawsuit. The Court noted that the act “requires a state court to place an Indian child with an Indian caretaker, if one is available, even if the child is already living with a non-Indian family and the state court thinks it in the child’s best interest to stay there.” That is, the ICWA may require a placement that the court believes is not in the child’s best interest.⁵

Decision. The constitutional claim in the case was that Congress lacked the authority to impose these substantial rules on states in making child custody decisions. The Supreme Court, in a 7-2 decision, upheld the constitutionality of the ICWA. The Court found the authority primarily in Article 1, Section 8, giving Congress the power to “regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes.” In addition, the Court suggested that the treaty power and “principles inherent in the Constitution’s structure may empower Congress to act in the field of Indian affairs.”

The amici brief

The joint amici brief of the American Academy of Pediatrics (AAP) and the AMA argued that tribes are “extended families” of Native American children.⁶ It noted the destructive history of removing Native American children from their families and suggested that kinship care improves children’s health. To its credit, the brief also honestly noted the serious mental health and suicide rates in some tribes, which suggest issues that might arise in child custody and adoption cases.

The Court did not, in this case, take up another constitutional issue that the parties raised—whether the strong preference for Native American over non ̶ Native American custody violates the Equal Protection Clause of the 14th Amendment. The Court said the parties to this case did not have standing to raise the issue. Justice Kavanaugh, concurring, said it was a “serious” issue and invited it to be raised in another case.⁵

False Claims Act cases

The case: Costs for SuperValu prescriptions

For physicians and health care organizations, False Claims Act (FCA) cases are an ongoing burden and, some would say, threat. (There are also state FCAs, but here we are discussing the federal act.) The federal government has recovered more than $70 billion since 1986, most from health care entities.⁷ The Justice Department identifies “health care fraud” as the largest area of FCA recovery and provides annual details on frauds resulting in liability.⁸

The legal claim. One FCA case this Term involved billings SuperValu made for outpatient prescriptions in Medicare-Medicaid programs. As its “usual and customary” costs, it essentially reported a list price that did not include the substantial discounts it commonly gave.⁹ The charge was that it “knowingly” made a false claim regarding the price of prescriptions. The question was what state of mind, or “scienter,” is required for “knowingly.” Should it be objective (what a reasonable person would know) or subjective (the defendant’s “knowledge and subjective beliefs”)?

Background. Subjective knowledge (what the defendant actually knows) may seem impossible to prove—the defendant could just say, “I did not know I was doing wrong.” Over time the law has developed several ways of demonstrating “knowing.” Justice Thomas, writing for a unanimous Court, held that whistleblowers or the government might prove “knowing” in 3 ways:

1. defendants “actually knew that their reported prices were not their ‘usual and customary’ prices when they reported them”

2. were aware of a substantial risk that their higher, retail prices were not their “usual and customary” prices and intentionally avoided learning whether their reports were accurate

3. were aware of such a substantial and unjustifiable risk but submitted the claims anyway.⁹

Of course, records of the company, information from the whistleblower, and circumstantial evidence may be used to prove any of these; it does not require the company’s admission.

The Court said that if the government or whistleblowers make a showing of any of these 3 things, it is enough.

Decision. The case was returned to the lower court to apply these rules.

The amici brief

The American Hospital Association and America’s Health Insurance Plans filed an amici brief.¹⁰ It reminded the Court that many reimbursement regulations are unclear. Therefore, it is inappropriate to impose FCA liability for guessing incorrectly what the regulations mean. Having to check on every possible ambiguity was unworkable. The Court declined, however, the suggestion that defendants should be able to use any one of many “objectively” reasonable interpretations of regulations.

Continue to: The case: Polansky v Executive Health Resources...

The case: Polansky v Executive Health Resources

Health care providers who dislike the FCA may find solace this Term in this second FCA case.¹¹

The legal claim. Polansky, a physician employed by a medical billing company, became an “intervenor” in a suit claiming the company assisted hospitals in false billing (inpatient claims for outpatient services). The government sought to dismiss the case, but Polansky refused.

Decision. The case eventually reached the Supreme Court, which held that the government may enter an FCA case at any time and move to dismiss the case even over the objection of a whistleblower. The government does not seek to enter a case in order to file dismissal motions often. When it does so, whistleblowers are protected by the fact that the dismissal motion requires a hearing before the federal court.

An important part of this case has escaped much attention. Justices Thomas, Kavanaugh, and Barrett invited litigation to determine if allowing private whistleblowers to represent the government’s interest is consistent with Article II of the Constitution.¹¹ The invitation will likely be accepted. We expect to see cases challenging the place of “intervenors” pursuing claims when the government has declined to take up the case. The private intervenor is a crucial provision of the current FCA, and if such a challenge were successful, it could substantially reduce FCA cases.

Criminal false claims

Another case this Term is cautionary about the consequences of health care misbilling. It resulted in a criminal charge. More importantly, in addition to a basic fraud charge, the government added a charge of aggravated identity theft,¹² which carries a mandatory 2-year prison sentence.

Dubin overbilled Medicaid for psychological testing by saying the testing was done by a licensed psychologist rather than an assistant. The government claimed the “identity theft” was using the patient’s (actual) Medicaid number in submitting the bill.¹² The Court unanimously held the overbilling was not aggravated identity theft as defined in federal law. Dubin could be convicted of fraudulent billing but not aggravated identity theft, thereby avoiding the mandatory prison term.

Patents of “genus” targets

The case: Amgen v Sanofi

This case, which corrected an error of the patent office, received little attention but was likely a turning point in the next generation of pharmaceuticals.¹³

Background. “Genus” patents allow a single pharmaceutical company to patent every antibody that binds to a specific amino acid on a naturally occurring protein. In this case, the patent office had granted a “genus” patent on “all antibodies” that bind to the naturally occurring protein PCSK9 and block it from hindering the body’s mechanism for removing low-density lipoprotein (LDL) cholesterol from the bloodstream,¹³ helping to reduce LDL cholesterol levels. These patents could involve millions of antibodies—and Amgen was claiming a patent on all of them. Amgen and Sanofi marketed their products, each with their own unique amino acid sequence.¹³ Amgen sued Sanofi for violating its patent rights.

Decision. The Court unanimously held that Amgen did not have a valid patent on all antibodies targeting PCSK9, only those that it had explicitly described in its patent application—a ruling based on a 150-year-old technical requirement for receiving a patent. An applicant for a patent must include “a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art…to make and use the same.”¹³ Amgen’s patent provided the description for only a few of the antibodies, but from the description in its application others could not “make and use” all of the antibodies targeting PCSK9.

While the decision was vital for future pharmaceuticals, the patent principle on which it was based has an interesting history. The Court noted that it affected the telegraph (Morse lost part of his patent), electric lights (Edison won his case against other inventors), and the glue for wood veneering (Perkins Glue Company lost).¹³

Other notable decisions

Student loans

The Court struck down the Biden Administration’s student loan forgiveness program, which would have cost approximately $430 billion.¹⁴ The central issue was whether the administration had the authority for such massive loan forgiveness; that is, whether Congress had authorized the broad loan forgiveness. The administration claimed authority from the post ̶ 9/11 HEROES Act, which allows the Secretary of Education to “waive or modify” loan provisions during national emergencies. The temporary hold on loan payments during COVID was based on this provision. However, in a 6-3 decision, the Court held that the act did not allow the secretary to cancel $430 billion in loans. “The Act allows the Secretary to ‘waive or modify’ existing statutory or regulatory provisions applicable to financial assistance programs under the Education Act, not to rewrite that statute from the ground up.”¹⁴

Free speech and the wedding web designer

303 Creative v Elenis involved a creative website designer who did not want to be required to create a website for a gay wedding.¹⁵ The designer had strong beliefs against same-sex marriages, but Colorado sought to force her to do so under the state “public accommodations” law. In a 6-3 decision, the Court held that the designer had a “free speech” right. That is, the state could not compel her to undertake speech expressing things she did not believe. This was because the website design was an expressive, creative activity and therefore was “speech” under the First Amendment.

Wetlands and the Clean Water Act

The essential issue in Sackett v Environmental Protection Agency (EPA) was the definitions of waters of the United States and related wetlands. The broad definition the EPA used meant it had jurisdiction to regulate an extraordinary amount of territory. It had, for example, prevented the Sacketts from building a modest house claiming it was part of the “waters of the United States because they were near a ditch that fed into a creek, which fed into Priest Lake, a navigable, intrastate lake.” The Court held that the EPA exceeded its statutory authority to define “wetlands.”¹⁶

The Court held that under the Clean Water Act, for the EPA to establish jurisdiction over adjacent wetlands, it must demonstrate that¹⁶:

1. “the adjacent body of water constitutes waters of the United States (ie, a relatively permanent body of water connected to traditional interstate navigable waters)…”

2. “…the wetland has a continuous surface connection with that water, making it difficult to determine where the water ends, and the wetland begins.”

Under this definition, the Sacketts could build their house. This was a statutory interpretation case. Therefore, Congress can expand or otherwise change the EPA’s authority under the Clean Water Act and other legislation.

Conclusions: A new justice, “shadow docket,” and ethics rules

SCOTUS’ newest member. When the Marshall called the Court into session on October 3, 2022, it had a new member, Justice Ketanji Brown Jackson. She was sworn in on June 30, 2022, when her predecessor (Justice Breyer) officially retired. She had been a law clerk for Justice Breyer in 1999, as well as a district court judge and court of appeals judge. Those who count such things described her as the “chattiest justice.”¹⁷ She spoke more than any other justice—by one count, a total of 75,632 words (an average of 1,300 words in each of the 58 arguments).

A more balanced Court? Most commentators view the Court as more balanced or less conservative than the previous Term. For example, Justice Sotomayor was in the majority 40% last Term but 65% this Term. Justice Thomas was in the majority 75% last Term but 55% this Term. Put another way, this Term in the divided cases, the liberal justices were in the majority 64% of the time, compared with the conservative justices 73%.¹⁸ Of course, these differences may reflect a different set of cases rather than a change in the direction of the Court. There were 11 (or 12, depending on how 1 case is counted) 6-3 cases, but only 5 were considered ideological. That suggests that, in many cases, the coalitions were somewhat fluid.

“Shadow docket” controversy continues.¹⁹ Shadow docket refers to orders the Court makes that do not follow oral arguments and often do not have written opinions. The orders are all publicly available. This Term a close examination of the approximately 30 shadow docket opinions shows that the overwhelming majority were dissents or explanations about denials of certiorari. The Court ordered only a few stays or injunctions via the shadow docket. One shadow docket stay (that prevented a lower court order from going into effect) is particularly noteworthy. A federal judge had ordered the suspension of the distribution of mifepristone while courts considered claims that the US Food and Drug Administration (FDA) had improperly approved the drug. In a shadow docket order, the Court issued the stay to allow mifepristone to be sold while the case challenging its approval was heard.²⁰ The only opinion was a dissent from Justice Alito. But it also demonstrates the importance of the shadow docket. Without this intervention, in at least part of the country, the distribution of mifepristone would have been interrupted pending the outcome of the FDA cases.

In August, the Court delayed a settlement in the Purdue Pharma liability bankruptcy case.²¹ It also stayed an injunction of a lower court, thereby permitting federal “ghost guns” regulations to go into effect at least temporarily.²²

More ethics rules to come? Another area in which the Court faced criticism was formal ethics rules. The justices make financial disclosures, but these are somewhat ambiguous. There is likely to be increasing pressure for a more complete disclosure of non-financial relationships and more formal ethics rules. ●

Before the pandemic, most of the public probably had a fleeting and limited familiarity with lateral flow tests (LFTs), also known as rapid antigen tests. Perhaps they used, or awaited the results of, a lateral flow home pregnancy test, which detects human chorionic gonadotropin in urine.

Then came COVID-19, and the need for large-scale testing. By late 2022, more than 3 billion tests for SARS-CoV-2 had been done worldwide. Although testing with reverse-transcription polymerase chain reaction (PCR) is the gold standard for diagnosing COVID, LFTs made possible large-scale testing at low cost with rapid results.

As of Sept. 12, the Food and Drug Administration lists 32 rapid antigen tests with emergency use authorizations (EUAs) for home use.

Now, many experts conclude, it’s time to expand the role of LFTs so the technology can help detect a host of other diseases. In a Nature Reviews bioengineering report, global experts from the United States, the United Kingdom, and other countries pointed out that commercial LFTs are currently not available for four of the eight known priority diseases of epidemic potential: Crimean-Congo hemorrhagic fever, Middle East respiratory syndrome coronavirus, Nipah and other henipaviruses, and Rift Valley fever.

It is prime time, these experts and others contend, to build a global network of LFT research and development hubs to strengthen diagnostic capability.

Expansion should not only include more tests for more diseases, some experts say, but also make use of existing technology to provide “full-circle” care. After a rapid test, for instance, users could download a mobile phone app, transmit the results to their health care provider, and then set up an appointment if needed or get a prescribed medication at the pharmacy.
 

Medical community on board

Clinicians support increased availability of LFTs, said Eric J. Topol, MD, professor and executive vice president of Scripps Research, La Jolla, Calif.“Rapid antigen tests are critical, made a big difference in the pandemic, and will be used increasingly for many other applications in the years ahead,” Dr. Topol said in an email.

Physicians welcome their potential, agreed William Schaffner, MD, professor of preventive medicine and infectious disease specialist at Vanderbilt University Medical Center, Nashville, Tenn. At the start of the pandemic, when he was briefed about a lateral flow device in development, he said, “I was blown away by the technology, ease of use, rapidity of getting a result, its reasonable accuracy and its anticipated relatively low price.”

Clinicians would probably see many advantages to having more LFTs for more diseases, Dr. Schaffner said, because they are of use not only at home but also in doctors’ offices and in emergency departments. Their increased use “would help [people] make quick decisions about treatment, especially for flu and COVID.”
 

How LFTs work

LFTs are capable of targeting antigens, such as for the COVID tests, and antibodies such as IgG or IgM. The tests are also capable of detecting nucleic acids, although the availability of these tests is currently rare.

First, a sample from blood, urine, saliva or other bodily sources is placed onto a sample pad. It travels to a conjugate pad containing antibodies. If the target being looked for is present, the target and antibodies bind and, as the sample moves along to the test line, produces a positive result line along with the control line (to show that the test worked).
 

Global market outlook

By 2030, the lateral flow assays market is predicted to rise to $14.1 billion, according to a report issued in September by the firm Research and Markets. In 2022, the market was estimated at $9.4 billion, with $3.6 billion of that in the United States.

The report details the performances of 55 major competitors, such as Abbott Laboratories, Siemens, and QuidelOrtho, but smaller companies and start-ups are also involved in LFT development.
 

LFTs: Pros and cons

Although LFTs give rapid results, their accuracy is lower than that of PCR, especially the sensitivity. For COVID antigen LFTs, the sensitivity ranges from 34.1% to 88.1%, with an overall specificity of 99.6%, according to a Cochrane Review report. The analytical sensitivity performance of PCR testing for COVID is near 100%.

Everyone acknowledges the accuracy challenge of LFTs. The technologies “are generally thought to have limitations of detection that for some applications may present a challenge,” said Douglas C. Bryant, president and CEO of QuidelOrtho, San Diego, which counts the QuickVue rapid test for COVID detection among its products.

However, Mr. Bryant added, “as we saw during the pandemic, there was a place for more sensitive PCR-based technologies that are often run in a lab and there was a place for the use of rapid tests: The key is knowing the strengths and best use cases when applying the different technologies.”

One strength, he said, was that the tests “were shown to be highly effective at detecting active, infectious cases of SARS-CoV-2 and the rapid turnaround time allowed patients to isolate themselves from others quickly to help curb the spread of infection to others.” Another advantage was the ability to screen high-risk populations such as nursing homes to detect positive cases and help prevent outbreaks.

The pandemic familiarized people with the tests, said Jeremy Stackawitz, CEO of Senzo, a start-up in vitro diagnostics company developing an amplified LFT platform for rapid tests for flu, tuberculosis, COVID, and Clostridioides difficile. People liked using them. Physicians generally accepted them. It works great with tele-doc. It works great with personalized medicine.

Now, he said, people used to the COVID self-tests are asking: “Where is my strep test? Where is my sexual health test?”
 

FDA’s perspective on LFTs

The FDA has no one-size-fits-all standard for evaluating LFTs.

“LFTs are evaluated with respect to their individual indications and the pathway under which they are being reviewed,” said James McKinney, an FDA spokesperson. “A performance recommendation for one type of lateral flow test may not be appropriate for another.”

EUAs, such as those given for the COVID at-home tests, require different levels of evidence than traditional premarket review, he said, whether de novo marketing authorization, 510(k) premarket notification, or premarket approval. The EUAs are evaluated with a risk-benefit analysis to speed up the time it takes to make the devices available.

And, Mr. McKinney said, for some devices, the FDA provides recommendations on the expected performance through guidance documents. For instance, for rapid devices developed to detect influenza A virus antigen, the FDA recommends including enough sample to generate sensitivity of greater than 60% and testing at least 50 samples.
 

LFTs: The potential, the challenges

Mr. Stackawitz predicted that, as more LFT self-tests become available, more people will seek care, just as they did with the COVID rapid tests. A 22-year-old who thinks he has chlamydia may balk at going to a doctor right away. However, “if he can go buy a soda and a test at CVS, it’s different, it really is. With a little anonymity, people will seek care.”

He has a vision shared by other experts: That testing technology will evolve so that after getting the results at home, people would follow through by sending those results to their health care provider and obtaining needed care or medication. In his opinion, this is superior to the traditional way, which often involves visiting a doctor with symptoms, going for tests, waiting for results, and then beginning treatment.

“It would make more sense if you came in knowing your results,” Mr. Stackawitz said. “It’s a much smarter pathway, gives better outcomes for the patient, is much quicker and at much less cost. And it frees up time for doctors. I think most physicians would embrace that.”

Although rapid testing is gaining well-deserved recognition, funding is an issue, according to the Nature Reviews report. Those experts warned that “a reduction in funding for LFT research post COVID-19 may hamper efforts to capitalize on gains in decentralized testing, especially self-testing, which may be critical to address future pandemic threats.”

Expansion should not only include more tests for more diseases, some experts say, but also make use of existing technology to provide “full-circle” care. After a rapid test, for instance, users could download a mobile phone app, transmit the results to their health care provider, and then set up an appointment if needed or get a prescribed medication at the pharmacy.
 

Medical community on board

Clinicians support increased availability of LFTs, said Eric J. Topol, MD, professor and executive vice president of Scripps Research, La Jolla, Calif.“Rapid antigen tests are critical, made a big difference in the pandemic, and will be used increasingly for many other applications in the years ahead,” Dr. Topol said in an email.

Physicians welcome their potential, agreed William Schaffner, MD, professor of preventive medicine and infectious disease specialist at Vanderbilt University Medical Center, Nashville, Tenn. At the start of the pandemic, when he was briefed about a lateral flow device in development, he said, “I was blown away by the technology, ease of use, rapidity of getting a result, its reasonable accuracy and its anticipated relatively low price.”

Clinicians would probably see many advantages to having more LFTs for more diseases, Dr. Schaffner said, because they are of use not only at home but also in doctors’ offices and in emergency departments. Their increased use “would help [people] make quick decisions about treatment, especially for flu and COVID.”
 

How LFTs work

LFTs are capable of targeting antigens, such as for the COVID tests, and antibodies such as IgG or IgM. The tests are also capable of detecting nucleic acids, although the availability of these tests is currently rare.

First, a sample from blood, urine, saliva or other bodily sources is placed onto a sample pad. It travels to a conjugate pad containing antibodies. If the target being looked for is present, the target and antibodies bind and, as the sample moves along to the test line, produces a positive result line along with the control line (to show that the test worked).
 

Global market outlook

By 2030, the lateral flow assays market is predicted to rise to $14.1 billion, according to a report issued in September by the firm Research and Markets. In 2022, the market was estimated at $9.4 billion, with $3.6 billion of that in the United States.

The report details the performances of 55 major competitors, such as Abbott Laboratories, Siemens, and QuidelOrtho, but smaller companies and start-ups are also involved in LFT development.
 

LFTs: Pros and cons

Although LFTs give rapid results, their accuracy is lower than that of PCR, especially the sensitivity. For COVID antigen LFTs, the sensitivity ranges from 34.1% to 88.1%, with an overall specificity of 99.6%, according to a Cochrane Review report. The analytical sensitivity performance of PCR testing for COVID is near 100%.

Everyone acknowledges the accuracy challenge of LFTs. The technologies “are generally thought to have limitations of detection that for some applications may present a challenge,” said Douglas C. Bryant, president and CEO of QuidelOrtho, San Diego, which counts the QuickVue rapid test for COVID detection among its products.

However, Mr. Bryant added, “as we saw during the pandemic, there was a place for more sensitive PCR-based technologies that are often run in a lab and there was a place for the use of rapid tests: The key is knowing the strengths and best use cases when applying the different technologies.”

One strength, he said, was that the tests “were shown to be highly effective at detecting active, infectious cases of SARS-CoV-2 and the rapid turnaround time allowed patients to isolate themselves from others quickly to help curb the spread of infection to others.” Another advantage was the ability to screen high-risk populations such as nursing homes to detect positive cases and help prevent outbreaks.

The pandemic familiarized people with the tests, said Jeremy Stackawitz, CEO of Senzo, a start-up in vitro diagnostics company developing an amplified LFT platform for rapid tests for flu, tuberculosis, COVID, and Clostridioides difficile. People liked using them. Physicians generally accepted them. It works great with tele-doc. It works great with personalized medicine.

Now, he said, people used to the COVID self-tests are asking: “Where is my strep test? Where is my sexual health test?”
 

FDA’s perspective on LFTs

The FDA has no one-size-fits-all standard for evaluating LFTs.

“LFTs are evaluated with respect to their individual indications and the pathway under which they are being reviewed,” said James McKinney, an FDA spokesperson. “A performance recommendation for one type of lateral flow test may not be appropriate for another.”

EUAs, such as those given for the COVID at-home tests, require different levels of evidence than traditional premarket review, he said, whether de novo marketing authorization, 510(k) premarket notification, or premarket approval. The EUAs are evaluated with a risk-benefit analysis to speed up the time it takes to make the devices available.

And, Mr. McKinney said, for some devices, the FDA provides recommendations on the expected performance through guidance documents. For instance, for rapid devices developed to detect influenza A virus antigen, the FDA recommends including enough sample to generate sensitivity of greater than 60% and testing at least 50 samples.
 

LFTs: The potential, the challenges

Mr. Stackawitz predicted that, as more LFT self-tests become available, more people will seek care, just as they did with the COVID rapid tests. A 22-year-old who thinks he has chlamydia may balk at going to a doctor right away. However, “if he can go buy a soda and a test at CVS, it’s different, it really is. With a little anonymity, people will seek care.”

He has a vision shared by other experts: That testing technology will evolve so that after getting the results at home, people would follow through by sending those results to their health care provider and obtaining needed care or medication. In his opinion, this is superior to the traditional way, which often involves visiting a doctor with symptoms, going for tests, waiting for results, and then beginning treatment.

“It would make more sense if you came in knowing your results,” Mr. Stackawitz said. “It’s a much smarter pathway, gives better outcomes for the patient, is much quicker and at much less cost. And it frees up time for doctors. I think most physicians would embrace that.”

Although rapid testing is gaining well-deserved recognition, funding is an issue, according to the Nature Reviews report. Those experts warned that “a reduction in funding for LFT research post COVID-19 may hamper efforts to capitalize on gains in decentralized testing, especially self-testing, which may be critical to address future pandemic threats.”
