The social behavior associated with the COVID-19 pandemic may have reduced the incidence of Kawasaki disease, according to results of a cohort study of nearly 4,000 children.

The incidence of Kawasaki disease in the United States declined by 28.2% between 2018 and 2020, possibly as a result of factors including school closures, mask mandates, and reduced ambient pollution that might reduce exposure to Kawasaki disease (KD) in the environment, but a potential association has not been explored, wrote Jennifer A. Burney, PhD, of the University of California, San Diego, and colleagues.

KD received greater attention in the public and medical communities because of the emergence of multisystem inflammatory syndrome in children (MIS-C), which is similar to, but distinct from, KD, and because of the noticeable drop in KD cases during the pandemic, the researchers said.

In a multicenter cohort study published in JAMA Network Open , the researchers reviewed data from 2,461 consecutive patients with KD who were diagnosed between Jan. 1, 2018, and Dec. 31, 2020. They conducted a detailed analysis of analysis of 1,461 children with KD who were diagnosed between Jan. 1, 2002, and Nov. 15, 2021, at Rady Children’s Hospital San Diego (RCHSD), using data from before, during, and after the height of the pandemic. The median age of the children in the RCHSD analysis was 2.8 years, 62% were male, and 35% were Hispanic.

Overall, the prevalence of KD declined from 894 in 2018 to 646 in 2020, across the United States, but the decline was uneven, the researchers noted.

In the RCHSD cohort in San Diego, KD cases in children aged 1-5 years decreased significantly from 2020 to 2021 compared to the mean number of cases in previous years (22 vs. 44.9, P = .02). KD cases also decreased significantly among males and Asian children.

Notably, the occurrence of the KD clinical features of strawberry tongue, enlarged cervical lymph node, and subacute periungual desquamation decreased during 2020 compared with the baseline period, although only strawberry tongue reached statistical significance (39% vs. 63%, P = .04). The prevalence of patients with an enlarged lymph node was 21% in 2020 vs. 32% prior to the pandemic (P = .09); the prevalence of periungual desquamation during these periods was 47% vs. 58%, P = .16).

The researchers also used data from Census Block Groups (CBGs) to assess the impact of mobility metrics and environmental exposures on KD during the pandemic for the San Diego patient cohort. They found that KD cases during the pandemic were more likely to occur in neighborhoods of higher socioeconomic status, and that neighborhoods with lower levels of nitrous oxides had fewer KD cases.

Overall, “The reduction in KD case numbers coincided with masking, school closures, reduced circulation of respiratory viruses, and reduced air pollution,” the researchers wrote in their discussion of the findings. “A rebound in KD case numbers to prepandemic levels coincided with the lifting of mask mandates and, subsequently, the return to in-person schooling,” they wrote.

The study findings were limited by several factors including the small sample sizes, which also limit the interpretation of mobility and pollution data, the researchers noted. Other limitations include the high interannual variability of KD and the inclusion of 2021 rebound data from the San Diego region only.

“Although our original hypothesis was that shelter-in-place measures would track with reduced KD cases, this was not borne out by the San Diego region data. Instead, the San Diego case occurrence data suggest that exposures that triggered KD were more likely to occur in the home, with a shift toward households with higher SES during the pandemic,” the researchers noted. However, “The results presented here are consistent with a respiratory portal of entry for the trigger(s) of KD,” they said.
 

Study fails to validate its conclusions

“This study attempts to test the hypothesis that various social restrictions were associated with a decrease in rate of diagnosed Kawasaki disease cases during portions of the SARS-CoV-2 pandemic,” Mark Gorelik, MD, assistant professor of pediatrics at Columbia University, New York, said in an interview.

“However, it appears that it fails to achieve this conclusion and I disagree with the findings,” said Dr. Gorelik, who was not involved in the study but served as first author on an updated Kawasaki disease treatment guideline published earlier this spring in Arthritis & Rheumatology.

“The study does not find statistically significant associations either with shelter in place orders or with cell phone mobility data, as stated in the conclusion, directly contradicting its own claim,” Dr. Gorelik said. “Secondly, the study makes an assumption that various methods, especially the wearing of masks by children and school closures, had a significant effect on the spread of respiratory viruses. There are no prospective, population based, controlled real world studies that validate this claim, and two prospective controlled real-world studies that dispute this,” he emphasized. “Cloth masks and surgical masks, which were the types of masks worn by school students, are also known to have a nonsignificant and paltry – in the latter, certainly less than 50%, and perhaps as little as 10% – effect on the reduction of respiratory viral spread,” he added.

“Mechanistic studies on mask wearing may suggest some mask efficacy, but these studies are as valid as mechanistic studies showing the effect of various antifungal pharmaceuticals on the replication of SARS-CoV-2 virus in culture, meaning only valid as hypothesis generating, and ultimately the latter hypothesis failed to bear out,” Dr. Gorelik explained. “We do not know the reason why other respiratory viruses and non-SARS-CoV-2 coronaviruses declined during the pandemic, but we do know that despite this, the SARS-CoV-2 coronavirus itself did not appear to suffer the same fate. Thus, it is very possible that another factor was at work, and we know that during other viral pandemics, typically circulating viruses decline, potentially due to induction of interferon responses in hosts, in a general effect known as ‘viral interference,’ ” he said.

“Overall, we must have robust evidence to support benefits of hypotheses that have demonstrated clear damage to children during this pandemic (such as school closures), and this study fails to live up to that requirement,” Dr. Gorelik said.  

The study was supported by the Gordon and Marilyn Macklin Foundation and the Patient-Centered Outcomes Research Institute. Dr. Burney and Dr. Gorelik had no financial conflicts to disclose.

During the coronavirus pandemic, several substance use behaviors decreased among youths, namely drinking, smoking, vaping, and cannabis use, according to a recent study published in the journal Current Psychiatry Reports.

That likely happened because they had to spend more time at home and less time with their friends, the study authors wrote, adding that youth substance use should be monitored in the post-pandemic years.

“One of the driving factors for youth substance use is access to substances,” Hannah Layman, one of the co-authors and a social and behavioral sciences doctoral student at West Virginia University, said in a statement.

“With stay-at-home orders, virtual schooling, and social distancing, children have been spending more time with family and are more socially isolated from peers than before,” she said. “Although social isolation from peers may have a negative impact on their mental health, it may just be one of the desirable outcomes of the pandemic when considering substance use in children.”

Ms. Layman and colleagues analyzed 49 studies that followed substance use of alcohol, cannabis, tobacco, e-cigarettes/vaping, and other drugs among children, teens, and youths under age 24. The studies spanned across several countries, including 22 in North America and 19 in Europe.

The research team found that most studies across all categories reported reductions in prevalence, except for the category of “other drugs and unspecific drugs,” which included three studies that showed an increase in use and three studies that showed a decrease in use.

Teens and preteens tend to have easier access to alcohol, tobacco, cannabis products, and vaping products and see them as less serious than “hard drugs,” the authors said.

Future research should analyze the long-term effects of the pandemic on youth substance use, the study authors wrote, paying attention to differences by gender and those who face the highest risks for substance use. Previous studies have shown an increase in substance use among youths, particularly among those in low-income neighborhoods or in difficult family circumstances.

“Substance use can affect a young person’s body in many ways, such as the development of mental health issues (depression, anxiety, conduct problems, personality disorders, and suicidal thoughts), injuries due to accidents, decreased bone mineral density, preventing proper brain growth and function, delayed puberty, liver damage, and so much more,” Ms. Layman said.

Increased parent or caregiver supervision can help prevent substance use problems, she noted. Early intervention, open support in conversations, and ongoing education about the dangers of substance use can help as well.

“Our findings also identified the importance of improving youth mental health and the value of telemedicine to address young people’s needs during the pandemic,” she said.

Symptoms of obstructive sleep apnea (OSA) were significantly more common in children with autism spectrum disorder (ASD), compared with controls, based on data from 166 individuals up to age 18 years.

Autism spectrum disorder affects approximately 1 in 54 children in the United States, and recent studies have shown an increased risk of obstructive sleep apnea in this population, compared with the general pediatric population, wrote Pooja Santapuram, MD, of Vanderbilt University, Nashville, Tenn., and colleagues.

In a study published in the International Journal of Pediatric Ototrhinolaryngology , the researchers reviewed data from 166 children and adolescents up to 18 years of age with OSA who underwent adenotonsillectomy at a single center between 2019 and 2021. The primary objective was to assess OSA symptoms in children with and without ASD. The study population included 75 children with ASD and 91 controls. The average age of both the ASD group and control group was approximately 73 months.
 

OSA meets ASD

Obstructive sleep apnea is common in autism spectrum disorder. Children with OSA can present with a range of symptoms, including loud snoring, excessive daytime sleepiness, and changes in cognitive function. Some of these symptoms can overlap with and exacerbate symptoms of ASD, potentially delaying OSA diagnosis in children with both conditions. The primary objective of this study was to assess between-group difference in OSA symptomatology and age at OSA diagnosis in children with and without ASD. To do so, a retrospective chart review was conducted on the 166 pediatric patients.

Overall, significantly more OSA symptoms were reported in children with ASD, compared with controls (P < .001).

Lower autism severity was associated with an increased number of reported OSA symptoms (P = .006). There was not a significant between-group difference in age at OSA diagnosis (P = .999); however, lower autism severity was also associated with an increased age at diagnosis (P = .002). These findings suggest that OSA may present with a higher symptom burden in children with ASD, and children with lower ASD severity often experience delays in OSA diagnosis.

Interestingly, despite the known associations between obesity and OSA, children with an increased body mass index were not diagnosed with OSA at an earlier age in this sample population, the researchers indicated.

Because the current study revealed that children with less severe ASD are more likely to report an increased number of OSA symptoms and be diagnosed at a later age than children without ASD, clinicians should have a heightened sense for OSA evaluation in children with ASD, particularly in children with a lower severity of ASD and an increased BMI, the researchers concluded.

The research study was not externally funded, and the researchers reported that they had no conflicts of interest.

Setmelanotide, a melanocortin-4 receptor (MC4R) agonist, is the first FDA-approved therapy for BBS, a rare genetic disorder that impairs a hunger signal along the melanocortin-4 receptor (MC4R) pathway.

BBS affects an estimated 1,500-2,500 people in the United States.

Individuals with BBS typically have obesity that starts at age 1 along with insatiable hunger (hyperphagia). Available weight management options are generally unsuccessful.

Other symptoms may include retinal degeneration, reduced kidney function, or extra digits of the hands or feet.

Setmelanotide received priority review, orphan drug designation, and breakthrough designation for this new indication.

As previously reported, in November 2020, the FDA approved setmelanotide for weight management in adults and children as young as 6 years with obesity due to proopiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1 (PCSK1), or leptin receptor (LEPR) deficiency confirmed by genetic testing – who also have impaired hunger signaling from the brain.

These individuals have a normal weight at birth but develop persistent, severe obesity within months due to hyperphagia.

The FDA approval of Imcivree for BBS “represents a significant milestone for Rhythm [Pharmaceuticals], validating our strategy of developing Imcivree for people with hyperphagia and severe obesity caused by rare MC4R-pathway diseases and allowing us to provide our precision therapy to an established community of patients living with BBS and their families who are eagerly awaiting a new treatment option,” said David Meeker, MD, chair, president and CEO of Rhythm, in a press release.
 

Safety, effectiveness in 66-week trial in 44 patients

The safety and effectiveness of setmelanotidewas evaluated in a 66-week phase 3 clinical trial that enrolled 44 patients age 6 and older who had a diagnosis of BBS and obesity – defined as a body mass index greater than or equal to 30 kg/m2 or greater than or equal to 97th percentile for pediatric patients.

After an initial 14-week, randomized, double-blind, placebo-controlled treatment period, patients entered a 52-week, open-label period.

The trial met its primary endpoint and all key secondary endpoints, with statistically significant reductions in weight and hunger at 52 weeks on therapy.

• After 52 weeks of treatment, patients taking setmelanotide lost, on average, 7.9% of their initial BMI.
• 61% of patients lost 5% or more of their initial BMI, and 39% lost 10% or more of their initial BMI.
• In the 14-week, placebo-controlled treatment, on average, BMI dropped by 4.6% in the 22 patients treated with the study drug and dropped 0.1% in the 22 patients treated with placebo.
• At 52 weeks, the 14 patients aged 12 and older who were able to self-report their hunger had a significant –2.1 mean change in hunger score.

Setmelanotide is associated with the following warnings and precautions:

• Spontaneous penile erections in males and sexual adverse reactions in females. Instruct males with erection lasting longer than 4 hours to seek emergency medical attention.
• Depression and suicidal ideation. Monitor patients for new onset or worsening depression or suicidal thoughts or behaviors. Consider discontinuing the drug if patients have suicidal thoughts or behaviors or clinically significant or persistent depression symptoms.
• Skin pigmentation and darkening of preexisting nevi (moles). Examine skin before and during treatment.
• Setmelanotide is not approved for use in neonates or infants. Serious and fatal adverse reactions including “gasping syndrome” can occur in neonates and low-birth-weight infants treated with benzyl alcohol-preserved drugs.

The most common adverse reactions (with an incidence greater than or equal to 20%) included skin hyperpigmentation, injection site reactions, nausea, headache, diarrhea, abdominal pain, vomiting, depression, and spontaneous penile erection.

The FDA did not approve the company’s supplemental new drug application for setmelanotide in Alström syndrome.

“My soul is in deep anguish. How long, Lord, how long?” – Psalm 6

Lament is making a comeback. A once-common word in the 1800s, it fell steeply in popularity in the 20th century. Lately, I see it everywhere. It’s a beautiful word, capturing not only sorrow, but also weariness. It is also audacious, facing injustice and acknowledging that it ought not be this way, and communal, bearing witness to the shared hardship of being human. The Hebrew scriptures captured the experience of lament in the form of psalms, from the Greek, psalmoi or “words to accompany the music.” A few thousand years later, the words still resonate, especially in times of grief. “I am weary with my groaning; all the night make I my bed to swim; I water my couch with my tears.”

“Hair loss” is not the chief complaint you want to see when running behind in clinic – it’s never a 15-minute visit. A woman in her late 30s with wavy, light-brown hair that grew to her waistline was seated on the exam chair. When I sat across from her, I couldn’t see her scalp. No erythema or scale. No frontal band of hair loss. Just a bit thin everywhere. Perhaps another post-COVID telogen? This might be easy. I blew right by her mother, who was sitting in the corner of the room. Her black and white horizontal striped shirt seemed to match her gray and white hair. She looked worried.

Having perused my patient’s labs and done an exam, I announced that the diagnosis was telogen effluvium. “There are many possible causes, stress is a common one. Have you been under a lot of stress lately?” (The answer is always yes, thus providing a good foothold to climb out of a hair-loss visit). “Yes. My 1-year-old daughter died last year. She had choked on a cashew from a granola bar given by her sister.” I gasped and turned from her green eyes to her mom’s. Without saying a word, mom pleaded with me to help. “I don’t know what to say,” I said, “I’m so sorry.” Neither replied.

On the commute home that day I listened to a live recording of the U2 song, “40.” I had recently read about it in a touching essay about lament by Enuma Okoro of the Financial Times. I thought about my patient’s suffering and the brutal injustice of fate. It feels like it’s everywhere lately. Reporting from the events in Ukraine, Buffalo, Uvalde, Tulsa has put agonized faces like hers in the public square for us all to gape at and quietly mourn.

Even from a secular lens, it can be seen that a beauty of psalms is how they move from despair to hope. Prayers will be answered. Things will get better. Turn up the volume and feel the urgency and pathos Bono injects into your soul as he sings the refrain; “How long, how long? How long to sing this song?” In the live version we the audience take over for him. The words accompanying the music swell over the crowd. How much longer? How much more suffering? My patient’s hair will grow back. It will take years. All we can do is lament with her.

Longer circadian periods and irregular sleep were significantly associated with mental health problems in adolescents including depression, anxiety, suicidality, social anxiety, and panic disorder, according to results from a European study.

A range of psychiatric symptoms and conditions has been linked to sleep pathologies, wrote Liisa Kuula, PhD, of the University of Helsinki, Finland, and colleagues. Some research suggests that late circadian rhythms and irregular sleep patterns increase the risk for psychiatric conditions, but the association has not been well studied, especially in adolescents, although the onset of psychiatric problems often occurs at this age, they said.

In a study published in the Journal of Psychiatric Research (2022 Apr 4. doi: 10.1016/j.jpsychires.2022.03.056.), the investigators reviewed data from 342 adolescents who were part of SleepHelsinki! a large cohort study of delayed sleep phase disorder (DSPD) in adolescents. The mean age of the participants was 17.4 years, and 70% were female.

The participants completed the Mini International Neuropsychiatric Interview (MINI) and wore temperature loggers for 3 days to assess circadian rhythms. The primary outcome was the impact of circadian dynamics on different psychiatric problems. Delayed Sleep Phase (DSP) behavior was defined as going to sleep later than 1 a.m. at least three times a week.

Circadian length was determined through the temperature loggers worn for 3 days. Most participants also completed 1-week GeneActiv Original actigraphy measurements (wearing the actigraph for 1 week) and responded to the Morningness-Eveningness Questionnaire, which divided participants into three circadian preference groups: morning, intermediate, and evening. Sleep duration was calculated as total sleep time, sleep quality was estimated by sleep efficiency, and sleep timing was assessed by the midpoint of the sleep period.

Overall, the MINI interview results suggested that approximately one-third (36%) of the teens had at least one psychiatric problem, and 21% had comorbid conditions.

Severe depression was significantly associated with a longer circadian period (P = .002), while suicidality was significantly associated with a later midpoint and more irregular sleep (P = .007 for both).

Participants with agoraphobia slept longer than did those without, the researchers noted (P = .013). However, sleep duration was not significantly associated with other psychiatric conditions.

Manic episodes and psychotic disorders were associated with irregular sleep timing (P < .018 and P < .017, respectively).

When the researchers examined DSP and circadian preferences, they found that 21.5% of individuals with suicidality had characteristics of DSP, as did 21.5% of those with panic disorder.

Individuals with a preference for eveningness were significantly more likely to meet criteria for severe depression, panic disorder, generalized anxiety disorder, and obsessive-compulsive disorder than were those without a preference for eveningness, the researchers noted.

“Our findings are the first to encompass diverse circadian measures alongside an array of psychiatric symptoms in such a focused age range,” the researchers wrote in their discussion. The data reflect results from other studies and extend the likely role of circadian patterns in mental wellbeing, they said.

The study findings were limited by several factors including the lack of actual diagnoses from medical records and use of self-reported symptoms, the researchers noted. Other limitations included the lack of polysomnography data and small size of subgroups of the study sample.

However, the results were strengthened by the heterogenous study population and use of multiple measures to examine sleep and circadian rhythms, as well as consideration of personal circadian preferences, the researchers said.

“The importance of overall synchronization with environment is perhaps best highlighted by response to treatment: most psychopathologic symptoms benefit from sleep-targeted therapeutic approaches,” they concluded.

The study received no outside funding. The researchers had no financial conflicts to disclose.

What would you do if you believed you had a serious health issue, but the best way to find out for sure might kill you?

That’s the reality for patients who wish to confirm or rule out a food allergy, says Sindy Tang, PhD, an associate professor of mechanical engineering at Stanford (Calif.) University.

And it’s the reason Dr. Tang and her colleagues are developing a food allergy test that’s not only safer, but also more reliable than today’s tests. In a paper in the journal Lab on a Chip, Dr. Tang and her colleagues outline the basis for this future test, which isolates a food allergy marker from the blood using a magnetic field.
 

How today’s food allergy tests fall short

The gold standard for food allergy diagnosis is something called the oral food challenge. That’s when the patient eats gradually increasing amounts of a problem food – say, peanuts – every 15 to 30 minutes to see if symptoms occur. This means highly allergic patients may risk anaphylaxis, an allergic reaction that causes inflammation so severe that breathing becomes restricted and blood pressure drops. Because of that, a clinical team must be at the ready with treatments like oxygen, epinephrine, or albuterol.

“The test is very accurate, but it’s also potentially unsafe and even fatal in rare cases,” Dr. Tang says. “That’s led to many sham tests advertised online that claim to use hair samples for food tests, but those are inaccurate and potentially dangerous, since they may give someone a false sense of confidence about a food they should avoid.”

Less risky tests are available, such as skin-prick tests – those involve scratching a small amount of the food into a patient’s arm – as well as blood tests that measure allergen-specific antibodies.

“Unfortunately, both of those are not that accurate and have high false-positive rates,” Dr. Tang says. “The best method is the oral food challenge, which many patients are afraid to do, not surprisingly.”
 

The future of food allergy testing: faster, safer, more reliable

In their study, the Stanford researchers focused on a type of white blood cell known as basophils, which release histamine when triggered by allergens. By using magnetic nanoparticles that bind to some blood cells but not basophils, they were able to separate basophils from the blood with a magnetic field in just 10 minutes.

Once isolated, the basophils are exposed to potential allergens. If they react, that’s a sign of an allergy.

Basophils have been isolated in labs before but not nearly this quickly and efficiently, Dr. Tang says.

“For true basophil activation, you need the blood to be fresh, which is challenging when you have to send it to a lab,” Dr. Tang says. “Being able to do this kind of test within a clinic or an in-house lab would be a big step forward.”
 

Next steps

While this represents a breakthrough in basophil activation testing, more research is needed to fully develop the system for clinical use. It must be standardized, automated, and miniaturized, the researchers say.

That said, the results give hope to those with food allergies that tomorrow’s gold-standard test will require only a blood sample without an emergency team standing by.

What would you do if you believed you had a serious health issue, but the best way to find out for sure might kill you?

That’s the reality for patients who wish to confirm or rule out a food allergy, says Sindy Tang, PhD, an associate professor of mechanical engineering at Stanford (Calif.) University.

And it’s the reason Dr. Tang and her colleagues are developing a food allergy test that’s not only safer, but also more reliable than today’s tests. In a paper in the journal Lab on a Chip, Dr. Tang and her colleagues outline the basis for this future test, which isolates a food allergy marker from the blood using a magnetic field.

Heat waves are getting hotter and becoming more frequent because of rising rates of air pollution, putting children’s health at risk, a wide-ranging new report finds.

An article in the New England Journal of Medicine reviews current research to take a sweeping inventory of how air pollution and climate change interact to adversely affect people’s health, especially that of kids. It examined the link between fossil fuel emissions and a variety of consequences of climate change – including extreme weather events; wildfires; vector-borne illnesses such as malaria, Zika, and Lyme disease; and heat waves, a topic at the forefront of many people’s minds.

This month, for example, record-high temperatures have been reported across the United States, affecting more than 100 million people and touching locations from the Gulf Coast to the Great Lakes, the Southwest, the mid-Atlantic, and the Midwest.

In Texas, Austin has already experienced an 8-day streak of temperatures above the 100° F mark in June, according to the Austin American-Statesman.

These patterns are an important reality to note, said Frederica Perera, DrPH, PhD, the article’s lead author. “My concern is that the threats are rising as temperature is rising,” Dr. Perera, a professor at Columbia University’s Mailman School of Public Health, New York, told KHN. “Temperatures are rising because greenhouse gas emissions are rising, and that’s a great concern for everyone’s health – but especially the most vulnerable.”

Children fit into this category, wrote Dr. Perera and her coauthor, Kari Nadeau, MD, PhD, Naddisy Foundation Endowed Professor of Medicine and Pediatrics at Stanford (Calif.) University, because their ability to regulate temperature, known as thermoregulation, is not fully developed.

They are also more susceptible to heat-related stress because they’re smaller and need to drink and eat more frequently to stay healthy, said Dr. Perera. But because “young children are dependent on parents to provide, sometimes their needs go ignored,” she said.

The authors noted that heat-related illness is “a leading and increasing cause of death and illness among student athletes” in the United States. In addition, they cited studies suggesting that “the heat associated with climate change” takes a toll on the mental health of children and adolescents, as well as their ability to learn.

The review article pointed to previous research. that associated in utero exposure to heat waves with “increased risks of preterm birth or low birth weight; hyperthermia and death among infants; and heat stress, kidney disease, and other illnesses” among kids.

“Being pregnant is very physiologically demanding in itself, and then heat places additional stress on a pregnant woman,” said Dr. Robert Dubrow, a professor of epidemiology at Yale’s School of Public Health, New Haven, Conn., who was not associated with either study. “And the fetus can experience heat stress as well, which could result in adverse birth outcomes.”

And these heat-related risks are across-the-board greater for “low-income communities and communities of color,” wrote the authors of the new article.

Carbon dioxide emissions from burning fossil fuels have risen sharply in the past 70 years, according to the article. “Modeling indicates that some heat waves would be extraordinarily unlikely to occur in the absence of climate change,” it says.

The authors briefly outline solutions that they describe as “climate and environmental strategies” that “should also be seen as essential public health policy.” Beyond big-picture efforts to mitigate fossil fuel and greenhouse gas emissions, they offered various ways to protect children – steps they term “adaptation measures” – which included providing clean water to children and families facing drought or water contamination and creating shaded areas where children play, live, and go to school.

Separately, Austin-based research highlighted why this step could be meaningful.

Researchers tracked the physical activity levels and location of students ages 8 to 10 during recess at three elementary schools in 2019. They compared children’s activity at recess during two weeks in September, the hottest full month during the school year, to a cooler week in November. “We wanted to understand the impact of outdoor temperatures on children’s play in schoolyard environments,” said Dr. Kevin Lanza, the study’s lead investigator, to inform the design of “future school-based interventions for physical activity in the face of climate change.”

During the hotter periods, he said, “children engaged in less physical activity and sought shade.”

As temperatures continue to rise, he said, schools must be flexible in making sure students are getting the daily exercise they need. “Schools should consider adding shade, either by planting trees or installing artificial structures that cover spaces intended for physical activity,” said Dr. Lanza, an assistant professor at UTHealth School of Public Health, Austin, Tex. He also noted that school policies could be updated so that recesses are scheduled during cooler times of the day and moved inside during periods of extreme heat.

But the overall need to protect kids from scorching weather patterns requires action beyond such steps, Dr. Perera said, and more climate and clean air policies must be enacted.

“Governments have the responsibility to protect the population and especially those most vulnerable, which especially includes children,” Dr. Perera said. “Action must be done immediately because we’re absolutely heading in the wrong direction.”

Erythema annulare centrifugum

A thorough body examination failed to reveal any other rashes or lesions suggestive of a fungal infection. A blood count and urinalysis were within normal limits. She had no lymphadenopathy or hepatosplenomegaly. A potassium hydroxide analysis of skin scrapings was negative for fungal elements. Punch biopsy of the skin on the left arm revealed focal intermittent parakeratosis, mildly acanthotic and spongiotic epidermis, and a tight superficial perivascular chronic dermatitis consisting of lymphocytes and histiocytes (Figures). Given these findings, a diagnosis of erythema annulare centrifugum (EAC) was rendered.

EAC is a rare, reactive skin rash characterized by redness (erythema) and ring-shaped lesions (annulare) that slowly spread from the center (centrifugum). The lesions present with a characteristic trailing scale on the inner border of the erythematous ring. Lesions may be asymptomatic or mildly pruritic and commonly involve the trunk, buttocks, hips, and upper legs. It is important to note that its duration is highly variable, ranging from weeks to decades, with most cases persisting for 9 months. EAC typically affects young or middle-aged adults but can occur at any age.

Erythema marginatum is a rare skin rash commonly seen with acute rheumatic fever secondary to streptococcal infection. It presents as annular erythematous lesions on the trunk and proximal extremities that are exacerbated by heat. It is often associated with active carditis related to rheumatic fever. This self-limited rash usually resolves in 2-3 days. Our patient was asymptomatic without involvement of other organs.

Like EAC, granuloma annulare is a benign chronic skin condition that presents with ring-shaped lesions. Its etiology is unknown, and lesions may be asymptomatic or mildly pruritic. Localized granuloma annulare typically presents as reddish-brown papules or plaques on the fingers, hands, elbows, dorsal feet, or ankles. The distinguishing feature of granuloma annulare from other annular lesions is its absence of scale.

Urticaria multiforme is an allergic hypersensitivity reaction commonly linked to viral infections, medications, and immunizations. Clinical features include blanchable annular/polycyclic lesions with a central purplish or dusky hue. Diagnostic pearls include the presence of pruritus, dermatographism, and individual lesions that resolve within 24 hours, all of which were not found in our patient’s case.

A recent series of columns on practice merger options generated a multitude of questions regarding merger, employment, and buyout agreements. The most common question was, “Do I really need to go to the trouble and expense of negotiating them?” If you have more than one physician in your group, you absolutely do need written contracts for a variety of reasons, but mostly to avoid conflicts later on. The proverbial “handshake agreement” is worthless in a major business dispute; everyone loses in such situations except the lawyers and accountants.

Mergers and buy-ins were covered at some length in my two previous columns. If the arrangement is to be one of employer and employees rather than a merger of equal partners, you will need an employment agreement to cover duties, requirements, expectations, and benefits. They define how each practitioner/employee will be paid, along with paid time off, health insurance, expense allowances, and malpractice coverage, among other basics. The more that is spelled out in the employment agreement, the fewer disagreements you are likely to have down the road.

Many employment contracts include a “termination without cause” clause, which benefits both the practice and the practitioners. It allows a practice to terminate a new associate if it feels a mistake has been made, even if he or she has done nothing wrong. On the other hand, the newcomer has the option to terminate if a better offer arises, their spouse hates the area, or for any other reason.

Buyouts should be addressed in advance as well. Several recent correspondents told me they didn’t see the necessity of writing a buyout agreement, because they plan to eventually sell their practice, rendering any buyout conditions moot. But what happens if an associate dies, becomes permanently disabled, or abruptly decides to leave the practice? If you haven’t prepared for such eventualities, you could find yourself receiving a demand from your ex-partner (or surviving spouse) for immediate payment of that partner’s portion of the practice’s value. And your valuation of the practice is likely to be severely at odds with the other party’s. Meanwhile, remaining partners must cover all the practice’s expenses and deal with an increased patient load.

A buyout agreement avoids these problems by planning for such eventualities in advance. You must agree on how a buyout amount will be valued. As I’ve said in previous columns, I strongly advise using a formula, not a fixed amount. If a buyout is based on 15- or 20-year-old reimbursements, the buyout will have no relationship to what the partners are currently being paid. Likewise, any buyout calculated at “appraised value” is a problem, because the buyout amount remains a mystery until an appraisal is performed. If the appraised value ends up being too high, the remaining owners may refuse to pay it. Have an actuary create a formula, so that a buyout figure can be calculated at any time. This area, especially, is where you need experienced, competent legal advice.

To avoid surprises, any buyout should require ample notice (6-12 months is common) to allow time to rearrange finances and recruit a new provider. Vesting schedules, similar to those used in retirement plans, are also popular. If a partner leaves before a prescribed time period has elapsed – say, 20 years – the buyout is proportionally reduced.

Buyouts can also be useful when dealing with noncompete agreements, which are notoriously difficult (and expensive) to enforce. One solution is a buyout penalty; a departing partner can compete with his or her former practice, but at the cost of a substantially reduced buyout. This permits competition, but discourages it, and compensates the targeted practice.

Buyouts are also a potential solution to some buy-in issues. A new associate entering an established practice may not be able to contribute assets equal to existing partners’ stakes and may lack the cash necessary to make up the difference. One alternative is to agree that any inequalities will be compensated at the other end in buyout value. Those partners contributing more assets will receive larger buyouts than those contributing less.

As I’ve said many times, these are not negotiations to undertake on your own. Enlist the aid of a consultant or attorney (or both) with ample medical practice experience.
