Despite recent advances in the diagnosis, treatment, and prevention of pediatric tuberculosis in children living with HIV (CLHIV) and HIV-exposed uninfected children (HEU), several unmet needs remain, including studies evaluating the feasibility of shortened TB treatment regimens.

“Children living with HIV contribute disproportionately to pediatric TB mortality rates, accounting for 16% of child TB deaths, and many cases are underdiagnosed and underreported,” said Nicole Salazar-Austin, MD, of Johns Hopkins University in Baltimore. She provided an update on pediatric TB prevention and treatment during an educational symposium at this year’s virtual Conference on Retroviruses & Opportunistic Infections.

Dr. Salazar-Austin summarized current diagnostics for pediatric TB and reviewed options for the prevention and treatment of TB in CLHIV and HEU.
 

TB and CLHIV

Presently, TB is the most common opportunistic infection among CLHIV, and those with severe immune suppression have a fivefold greater risk of TB disease. While antiretroviral therapy (ART) is highly protective against TB disease in CLHIV, only about 50% of eligible children receive ART.

Dr. Salazar-Austin explained that many individuals with TB/HIV coinfection are unaware of their coinfection and not receiving treatment. Despite recommendations, TB preventive therapy is poorly implemented in CLHIV, especially in high-burden settings.
 

Pediatric TB diagnosis

Smear microscopy, culture, and Xpert MTB/RIF Ultra are the main diagnostic modalities for pediatric TB. The Xpert MTB/RIF test is an automated PCR-based assay that simultaneously and rapidly detects Mycobacterium tuberculosis complex and resistance to rifampin. The test is currently recommended by the World Health Organization as the initial diagnostic method for presumptive TB cases in both adults and children.

However, under optimal conditions, only 40% of TB cases will be detected. This is in part due to limited implementation of sputum collection procedures, but recent evidence has shown that collection of multiple specimens improves sensitivity for both culture and Xpert MTB/RIF Ultra across all specimen types, Dr. Salazar-Austin explained.

In 2020, the WHO endorsed the use of stool samples for the diagnosis of pediatric pulmonary TB. Stool Xpert is an emerging alternative, noninvasive method for ruling in pediatric TB disease, and has shown sensitivity and specificity similar to that of Xpert MTB/RIF Ultra.

“TB diagnostics have limited sensitivity in children, and efforts are ongoing to maximize current diagnostics, but new diagnostics are needed,” said Dr. Salazar-Austin.
 

Pediatric TB treatment

Despite the high frequency of TB as an opportunistic infection in CLHIV, current data on co-treatment strategies are limited.

Dolutegravir-based regimens are the preferred first-line regimen for CLHIV. In June 2020, the Food and Drug Administration approved the dispersible dolutegravir tablet, and it is expected to become widely available in 2021.

In children with TB/HIV coinfection who receive dolutegravir and rifampicin, dolutegravir is typically dosed twice daily because of a known drug interaction, based on data from the ODYSSEY study. The WHO recommendations for treatment of pediatric TB/HIV coinfection were recently updated to reflect twice-daily dosing of dolutegravir.

Despite these new recommendations, data are currently limited, and observational pharmacokinetic studies evaluating twice daily dolutegravir with TB treatment in young children are needed.

“More work is needed to evaluate the drug-drug interactions and proper dosing of rifamycins with dolutegravir for the treatment and prevention of TB in CLHIV,” Dr. Salazar-Austin said.

Based on data from TBTC Study 31/ACTG A5349, high-dose rifapentine (a rifamycin) with moxifloxacin (a fluoroquinolone) was noninferior to rifapentine alone in newly diagnosed, culture positive, drug-susceptible TB in children 12 years and older.

Whether rifapentine and moxifloxacin (RPT-Mox) can be used in children under 12 years remains unknown, but future studies may help answer this question, Dr. Salazar-Austin noted. The FDA has restricted the use of fluoroquinolones in children because of a possible effect on cartilage development, she explained.

Furthermore, recent data from the SHINE trial suggested that shortened treatment regimens may hold promise for children with TB.

“While shortened TB treatment regimens hold promise, much work needs to be done in children to implement RPT-Mox, but the results from SHINE can be implemented rapidly,” Dr. Salazar-Austin said.

Dr. Salazar-Austin disclosed no conflicts of interest. The presentation was funded by NICHD, UNITAID, Fogarty Institute, and the IMPAACT network.

Another coronavirus surge may be on the way in the United States as daily COVID-19 cases continue to plateau around 60,000, states begin to lift restrictions, and people embark on spring break trips this week, according to CNN.

Outbreaks will likely stem from the B.1.1.7 variant, which was first identified in the United Kingdom, and gain momentum during the next 6-14 weeks.

“Four weeks ago, the B.1.1.7 variant made up about 1%-4% of the virus that we were seeing in communities across the country. Today it’s up to 30%-40%,” Michael Osterholm, PhD, director of the Center for Infectious Disease Research and Policy at the University of Minnesota, Minneapolis, told NBC’s Meet the Press on March 7.

Dr. Osterholm compared the current situation with the “eye of the hurricane,” where the skies appear clear but more storms are on the way. Across Europe, 27 countries are seeing significant B.1.1.7 case increases, and 10 are getting hit hard, he said.

“What we’ve seen in Europe, when we hit that 50% mark, you see cases surge,” he said. “So right now, we do have to keep America as safe as we can from this virus by not letting up on any of the public health measures we’ve taken.”

In January, the CDC warned that B.1.1.7 variant cases would increase in 2021 and become the dominant variant in the country by this month. The United States has now reported more than 3,000 cases across 46 states, according to the latest CDC tally updated on March 7. More than 600 cases have been found in Florida, followed by more than 400 in Michigan.

The CDC has said the tally doesn’t represent the total number of B.1.1.7 cases in the United States, only the ones that have been identified by analyzing samples through genomic sequencing.

“Where it has hit in the U.K. and now elsewhere in Europe, it has been catastrophic,” Celine Gounder, MD, an infectious disease specialist with New York University Langone Health, told CNN on March 7.

The variant is more transmissible than the original novel coronavirus, and the cases in the United States are “increasing exponentially,” she said.

“It has driven up rates of hospitalizations and deaths and it’s very difficult to control,” Dr. Gounder said.

Vaccination numbers aren’t yet high enough to stop the predicted surge, she added. The United States has shipped more than 116 million vaccine doses, according to the latest CDC update on March 7. Nearly 59 million people have received at least one dose, and 30.6 million people have received two vaccine doses. About 9% of the U.S. population has been fully vaccinated.

States shouldn’t ease restrictions until the vaccination numbers are much higher and daily COVID-19 cases fall below 10,000 – and maybe “considerably less than that,” Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, told CNN on March 4.

Several states have already begun to lift COVID-19 safety protocols, with Texas and Mississippi removing mask mandates last week. Businesses in Texas will be able to reopen at full capacity on March 10. For now, public health officials are urging Americans to continue to wear masks, avoid crowds, and follow social distancing guidelines as vaccines roll out across the country.

“This is sort of like we’ve been running this really long marathon, and we’re 100 yards from the finish line and we sit down and we give up,” Dr. Gounder told CNN on Sunday. ‘We’re almost there, we just need to give ourselves a bit more time to get a larger proportion of the population covered with vaccines.”

A single pill of the investigational drug molnupiravir taken twice a day for 5 days eliminated SARS-CoV-2 from the nasopharynx of 49 participants.

That led Carlos del Rio, MD, distinguished professor of medicine at Emory University, Atlanta, to suggest a future in which a drug like molnupiravir could be taken in the first few days of symptoms to prevent severe disease, similar to Tamiflu for influenza.

“I think it’s critically important,” he said of the data. Emory University was involved in the trial of molnupiravir but Dr. del Rio was not part of that team. “This drug offers the first antiviral oral drug that then could be used in an outpatient setting.”

Still, Dr. del Rio said it’s too soon to call this particular drug the breakthrough clinicians need to keep people out of the ICU. “It has the potential to be practice changing; it’s not practice changing at the moment.”

Wendy Painter, MD, of Ridgeback Biotherapeutics, who presented the data at the Conference on Retroviruses and Opportunistic Infections, agreed. While the data are promising, “We will need to see if people get better from actual illness” to assess the real value of the drug in clinical care.

“That’s a phase 3 objective we’ll need to prove,” she said in an interview.

Phase 2/3 efficacy and safety studies of the drug are now underway in hospitalized and nonhospitalized patients.

In a brief prerecorded presentation of the data, Dr. Painter laid out what researchers know so far: Preclinical studies suggest that molnupiravir is effective against a number of viruses, including coronaviruses and specifically SARS-CoV-2. It prevents a virus from replicating by inducing viral error catastrophe (Proc Natl Acad Sci U S A. 2002 Oct 15;99[21]:13374-6) – essentially overloading the virus with replication and mutation until the virus burns itself out and can’t produce replicable copies.

In this phase 2a, randomized, double-blind, controlled trial, researchers recruited 202 adults who were treated at an outpatient clinic with fever or other symptoms of a respiratory virus and confirmed SARS-CoV-2 infection by day 4. Participants were randomly assigned to three different groups: 200 mg of molnupiravir, 400 mg, or 800 mg. The 200-mg arm was matched 1:1 with a placebo-controlled group, and the other two groups had three participants in the active group for every one control.

Participants took the pills twice daily for 5 days, and then were followed for a total of 28 days to monitor for complications or adverse events. At days 3, 5, 7, 14, and 28, researchers also took nasopharyngeal swabs for polymerase chain reaction tests, to sequence the virus, and to grow cultures of SARS-CoV-2 to see if the virus that’s present is actually capable of infecting others.

Notably, the pills do not have to be refrigerated at any point in the process, alleviating the cold-chain challenges that have plagued vaccines.

“There’s an urgent need for an easily produced, transported, stored, and administered antiviral drug against SARS-CoV-2,” Dr. Painter said.

Of the 202 people recruited, 182 had swabs that could be evaluated, of which 78 showed infection at baseline. The results are based on labs of those 78 participants.

By day 3, 28% of patients in the placebo arm had SARS-CoV-2 in their nasopharynx, compared with 20.4% of patients receiving any dose of molnupiravir. But by day 5, none of the participants receiving the active drug had evidence of SARS-CoV-2 in their nasopharynx. In comparison, 24% of people in the placebo arm still had detectable virus.

Halfway through the treatment course, differences in the presence of infectious virus were already evident. By day 3 of the 5-day course, 36.4% of participants in the 200-mg group had detectable virus in the nasopharynx, compared with 21% in the 400-mg group and just 12.5% in the 800-mg group. And although the reduction in SARS-CoV-2 was noticeable in the 200-mg and the 400-mg arms, it was only statistically significant in the 800-mg arm.

In contrast, by the end of the 5 days in the placebo groups, infectious virus varied from 18.2% in the 200-mg placebo group to 30% in the 800-mg group. This points out the variability of the disease course of SARS-CoV-2.

“You just don’t know” which infections will lead to serious disease, Dr. Painter said in an interview. “And don’t you wish we did?”

Seven participants discontinued treatment, though only four experienced adverse events. Three of those discontinued the trial because of adverse events. The study is still blinded, so it’s unclear what those events were, but Dr. Painter said that they were not thought to be related to the study drug.

The bottom line, said Dr. Painter, was that people treated with molnupiravir had starkly different outcomes in lab measures during the study.

“An average of 10 days after symptom onset, 24% of placebo patients remained culture positive” for SARS-CoV-2 – meaning there wasn’t just virus in the nasopharynx, but it was capable of replicating, Dr. Painter said. “In contrast, no infectious virus could be recovered at study day 5 in any molnupiravir-treated patients.”

In contrast, by the end of the 5 days in the placebo groups, infectious virus varied from 18.2% in the 200-mg placebo group to 30% in the 800-mg group. This points out the variability of the disease course of SARS-CoV-2.

“You just don’t know” which infections will lead to serious disease, Dr. Painter said in an interview. “And don’t you wish we did?”

Seven participants discontinued treatment, though only four experienced adverse events. Three of those discontinued the trial because of adverse events. The study is still blinded, so it’s unclear what those events were, but Dr. Painter said that they were not thought to be related to the study drug.

The bottom line, said Dr. Painter, was that people treated with molnupiravir had starkly different outcomes in lab measures during the study.

“An average of 10 days after symptom onset, 24% of placebo patients remained culture positive” for SARS-CoV-2 – meaning there wasn’t just virus in the nasopharynx, but it was capable of replicating, Dr. Painter said. “In contrast, no infectious virus could be recovered at study day 5 in any molnupiravir-treated patients.”

A single pill of the investigational drug molnupiravir taken twice a day for 5 days eliminated SARS-CoV-2 from the nasopharynx of 49 participants.

That led Carlos del Rio, MD, distinguished professor of medicine at Emory University, Atlanta, to suggest a future in which a drug like molnupiravir could be taken in the first few days of symptoms to prevent severe disease, similar to Tamiflu for influenza.

“I think it’s critically important,” he said of the data. Emory University was involved in the trial of molnupiravir but Dr. del Rio was not part of that team. “This drug offers the first antiviral oral drug that then could be used in an outpatient setting.”

Still, Dr. del Rio said it’s too soon to call this particular drug the breakthrough clinicians need to keep people out of the ICU. “It has the potential to be practice changing; it’s not practice changing at the moment.”

Wendy Painter, MD, of Ridgeback Biotherapeutics, who presented the data at the Conference on Retroviruses and Opportunistic Infections, agreed. While the data are promising, “We will need to see if people get better from actual illness” to assess the real value of the drug in clinical care.

“That’s a phase 3 objective we’ll need to prove,” she said in an interview.

Phase 2/3 efficacy and safety studies of the drug are now underway in hospitalized and nonhospitalized patients.

In a brief prerecorded presentation of the data, Dr. Painter laid out what researchers know so far: Preclinical studies suggest that molnupiravir is effective against a number of viruses, including coronaviruses and specifically SARS-CoV-2. It prevents a virus from replicating by inducing viral error catastrophe (Proc Natl Acad Sci U S A. 2002 Oct 15;99[21]:13374-6) – essentially overloading the virus with replication and mutation until the virus burns itself out and can’t produce replicable copies.

In this phase 2a, randomized, double-blind, controlled trial, researchers recruited 202 adults who were treated at an outpatient clinic with fever or other symptoms of a respiratory virus and confirmed SARS-CoV-2 infection by day 4. Participants were randomly assigned to three different groups: 200 mg of molnupiravir, 400 mg, or 800 mg. The 200-mg arm was matched 1:1 with a placebo-controlled group, and the other two groups had three participants in the active group for every one control.

Participants took the pills twice daily for 5 days, and then were followed for a total of 28 days to monitor for complications or adverse events. At days 3, 5, 7, 14, and 28, researchers also took nasopharyngeal swabs for polymerase chain reaction tests, to sequence the virus, and to grow cultures of SARS-CoV-2 to see if the virus that’s present is actually capable of infecting others.

Notably, the pills do not have to be refrigerated at any point in the process, alleviating the cold-chain challenges that have plagued vaccines.

“There’s an urgent need for an easily produced, transported, stored, and administered antiviral drug against SARS-CoV-2,” Dr. Painter said.

Of the 202 people recruited, 182 had swabs that could be evaluated, of which 78 showed infection at baseline. The results are based on labs of those 78 participants.

By day 3, 28% of patients in the placebo arm had SARS-CoV-2 in their nasopharynx, compared with 20.4% of patients receiving any dose of molnupiravir. But by day 5, none of the participants receiving the active drug had evidence of SARS-CoV-2 in their nasopharynx. In comparison, 24% of people in the placebo arm still had detectable virus.

Halfway through the treatment course, differences in the presence of infectious virus were already evident. By day 3 of the 5-day course, 36.4% of participants in the 200-mg group had detectable virus in the nasopharynx, compared with 21% in the 400-mg group and just 12.5% in the 800-mg group. And although the reduction in SARS-CoV-2 was noticeable in the 200-mg and the 400-mg arms, it was only statistically significant in the 800-mg arm.

In contrast, by the end of the 5 days in the placebo groups, infectious virus varied from 18.2% in the 200-mg placebo group to 30% in the 800-mg group. This points out the variability of the disease course of SARS-CoV-2.

Diagnosis of bleeding disorders in girls and women can lag behind diagnosis in boys and men by more than a decade, meaning needless delays in treatment and poor quality of life for many with hemophilia or related conditions.

“There is increasing awareness about issues faced by women and girls with inherited bleeding disorders, but disparities still exist both in both access to diagnosis and treatment,” said Roseline D’Oiron, MD, from Hôpital Bicêtre in Paris.

“Diagnosis, when it is made, is often made late, particularly in women. Indeed, a recent study from the European Hemophilia Consortium including more than 700 women with bleeding disorders showed that the median age at diagnosis was 16 years old,” she said during the annual congress of the European Association for Haemophilia and Allied Disorders.

She said that delayed diagnosis of bleeding disorders in women and girls may be caused by a lack of knowledge by patients, families, and general practitioners about family history of bleeding disorders, abnormal bleeding events, and heavy menstrual bleeding. In addition, despite the frequency and severity of heavy bleeding events, patients, their families, and caregivers may underestimate the effect on the patient’s quality of life.
 

Disparities documented

Dr. D’Oiron pointed to several studies showing clear sex-based disparities in time to diagnosis. For example, a study published in Haemophilia showed that in 22 girls with hemophilia A or hemophilia B, the diagnosis of severe hemophilia was delayed by a median of 6.5 months compared with the diagnosis in boys, and a diagnosis of moderate hemophilia in girls was delayed by a median of 39 months.

In a second, single-center study comparing 44 women and girls with mild hemophilia (factor VIII or factor XI levels from 5 to 50 IU/dL) with 77 men and boys with mild hemophilia, the mean age at diagnosis was 31.63 years versus 19.18 years, respectively – a delay of 12.45 years.

A third study comparing 442 girls/women and 442 boys/men with mild hemophilia in France showed a difference of 6.07 years in diagnosis: the median age for girls/women at diagnosis was 16.91 years versus10.84 years for boys/men.
 

Why it matters

Dr. D’Oiron described the case of a patient named Clare, who first experienced, at age 8, 12 hours of bleeding following a dental procedure. At age 12.5, she began having heavy menstrual bleeding, causing her to miss school for a few days each month, to be feel tired, and have poor-quality sleep.

Despite repeated bleeding episodes, severe anemia, and iron deficiency, her hemophilia was not suspected until after her 16th birthday, and a definitive diagnosis of hemophilia in both Clare and her mother was finally made when Clare was past 17, when a nonsense variant factor in F8, the gene encoding for factor VIII, was detected.

“For Clare, it took more the 8 years after the first bleeding symptoms, and nearly 4 years after presenting with heavy menstrual bleeding to recognize that she had a bleeding problem,” she said.

In total, Clare had about 450 days of heavy menstrual bleeding, causing her to miss an estimated 140 days of school because of the delayed diagnosis and treatment.

“In my view, this is the main argument why it is urgent for these patients to achieve diagnosis early: this is to reduce the duration [of] a very poor quality of life,” Dr. D’Oiron said.
 

Barriers to diagnosis

Patients and families have reported difficulty distinguishing normal bleeding from abnormal symptoms, and girls may be reluctant to discuss their symptoms with their family or peers. In addition, primary care practitioners may not recognize the severity of the symptoms and therefore may not refer patients to hematologists for further workup.

These findings emphasize the need for improved tools to help patients differentiate between normal and abnormal bleeding, using symptom recognition–based language tools that can lead to early testing and application of accurate diagnostic tools, she said.

Standardization of definitions can help to improve screening and diagnosis, Dr. D’Oiron said, pointing to a recent study in Blood Advances proposing definitions for future research in von Willebrand disease.

For example, the authors of that study proposed a definition of heavy menstrual bleeding to include any of the following:

• Bleeding lasting 8 or more days
• Bleeding that consistently soaks through one or more sanitary protections every 2 hours on multiple days
• Requires use of more than one sanitary protection item at a time
• Requires changing sanitary protection during the night
• Is associated with repeat passing of blood clots
• Has a Pictorial Blood Assessment Chart score greater than 100.
•  

Problem and solutions

Answering the question posed in the title of her talk, Dr. D’Oiron said: “Yes, we do have a problem with the diagnosis of bleeding disorders in women and girls, but we also have solutions.”

The solutions include family and patient outreach efforts; communication to improve awareness; inclusion of general practitioners in the circle of care; and early screening, diagnosis, and treatment.

A bleeding disorders specialist who was not involved in the study said that Dr. D’Oiron’s report closely reflects what she sees in the clinic.

“I do pediatrics, and usually what happens is that I see a teenager with heavy menstrual bleeding and we take her history, and we find out that Mom and multiple female family members have had horrible menstrual bleeding, possibly many of whom have had hysterectomies for it, and then diagnosing the parents and other family members after diagnosing the girl that we’re seeing” said Veronica H. Flood, MD, from the Medical College of Wisconsin, Milwaukee.

“It is unfortunately a very real thing,” she added.

Reasons for the delay likely include lack of awareness of bleeding disorders.

“If you present to a hematologist, we think about bleeding disorders, but if you present to a primary care physician, they don’t always have that on their radar,” she said.

Additionally, a girl from a family with a history of heavy menstrual bleeding may just assume that what she is experiencing is “normal,” despite the serious affect it has on her quality of life, Dr. Flood said.

Dr. D’Oiron’s research is supported by her institution, the French Hemophilia Association, FranceCoag and Mhemon, the European Hemophilia Consortium, and the World Federation of Hemophilia. She reported advisory board or invited speaker activities for multiple companies. Dr. Flood reported having no conflicts of interest to disclose.

People who are fully vaccinated against COVID-19 can safely gather unmasked and inside with nonvulnerable people who are not yet immunized, according to long-awaited guidance released by the CDC.

“Today’s action represents an important first step. It is not our final destination,” CDC Director Rochelle Walensky, MD, said March 8 at a White House briefing. “As more people get vaccinated, levels of COVID-19 infection decline in communities, and as our understanding of COVID immunity improves, we look forward to updating these recommendations to the public.”

According to the new guidance, people who are at least 2 weeks out from their last dose can:

• Visit with other fully vaccinated people indoors without wearing masks or physical distancing.
• Visit with unvaccinated people from a single household who are at low risk for severe COVID-19 disease indoors without wearing masks or physical distancing
• Avoid quarantine and testing following exposure to someone if they remain asymptomatic.

However, there are still restrictions that will remain until further data are collected. Those who are fully vaccinated must still:

• Wear masks and physically distance in public settings and around people at high risk for severe disease.
• Wear masks and physically distance when visiting unvaccinated people from more than one household.
• Avoid medium- and large-sized gatherings.
• Avoid travel.

People considered at high risk for severe disease include older adults and those with cancer, chronic kidney disease, COPD, Down syndrome, heart disease, heart failure, a weakened immune system, obesity, sickle cell disease, and type 2 diabetes. The category also includes pregnant women and smokers.

“In public spaces, fully vaccinated people should continue to follow guidance to protect themselves and others, including wearing a well-fitted mask, physical distancing (at least 6 feet), avoiding crowds, avoiding poorly ventilated spaces, covering coughs and sneezes, washing hands often, and following any applicable workplace or school guidance,” the guidance says. “Fully vaccinated people should still watch for symptoms of COVID-19, especially following an exposure to someone with suspected or confirmed COVID-19.”

Respecting travel restrictions is still crucial, Dr. Walensky said, given past surges and variants that have emerged after periods of increased travel.

"We would like to give the opportunity for vaccinated grandparents to visit children and grandchildren who are healthy and local,” Dr. Walensky said.

But, she said, “It’s important to realize as we’re working through this that over 90% of the population is not yet vaccinated.”

For now, there are not enough data on transmission rates from those who are vaccinated to the rest of the public. However, Anthony Fauci, MD, said at a briefing last month that preliminary data are “pointing in a very favorable direction.”

Studies from Spain and Israel published last month showed the amount of viral load – or the amount of the COVID-19 virus in someone’s body – is significantly lower if someone gets infected after they’ve been vaccinated, compared with people who get infected and didn’t have the vaccine. Lower viral load means much lower chances of passing the virus to someone else, Dr. Fauci said.

“The science of COVID-19 is complex,” Dr. Walensky said, “and our understanding of it continues to evolve.”

For now, there are not enough data on transmission rates from those who are vaccinated to the rest of the public. However, Anthony Fauci, MD, said at a briefing last month that preliminary data are “pointing in a very favorable direction.”

Studies from Spain and Israel published last month showed the amount of viral load – or the amount of the COVID-19 virus in someone’s body – is significantly lower if someone gets infected after they’ve been vaccinated, compared with people who get infected and didn’t have the vaccine. Lower viral load means much lower chances of passing the virus to someone else, Dr. Fauci said.

“The science of COVID-19 is complex,” Dr. Walensky said, “and our understanding of it continues to evolve.”

Children with atopic dermatitis (AD) face a significantly greater risk of chronic school absenteeism compared with their peers with psoriasis and without AD or psoriasis.

In addition, parents of children with AD have significantly increased absenteeism from work compared with parents of children without AD.

Those are among key findings from a cross-sectional analysis of data from the Medical Expenditure Panel Surveys (MEPS), reported by Brian T. Cheng and Jonathan I. Silverberg, MD, PhD, MPH. The results were published online March 1 in the Journal of the American Academy of Dermatology.

“Atopic dermatitis is a debilitating disease that profoundly impacts children and their ability to attend school,” the study’s senior author, Dr. Silverberg, director of clinical research in the department of dermatology at George Washington University, Washington, said in an interview. “This is clinically relevant because school absenteeism is a sign of poorly controlled disease and should prompt clinicians to step up their game and aim for tighter control of the child’s atopic dermatitis.”

In an effort to determine the burden and predictors of chronic school absenteeism in children with AD, Mr. Cheng, a medical student at Northwestern University, Chicago, and Dr. Silverberg conducted a cross-sectional retrospective analysis of 124,267 children, adolescents, and young adults between the ages of 3 and 22 years from the 2000-2015 MEPS, which are representative surveys of the U.S. noninstitutionalized population conducted by the Agency for Healthcare Research and Quality. They used ICD-9 codes to determine a diagnosis of AD, psoriasis, and comorbidities; the primary outcome was chronic school absenteeism, defined as missing 15 or more days per year in the United States. MEPS also recorded the number of workdays that parents missed to care for their children or a relative.

The 124,267 individuals evaluated ranged in age between 3 and 22 years. Of these, 3,132 had AD and 200 had psoriasis. In the full cohort, chronic school absenteeism was higher among females, younger children, and those with lower household incomes, and public insurance.

Among children with AD, and those with psoriasis, 68% and 63% missed one or more day of school due to illness, respectively, while 4% in each group missed 15 days or more. Logistic regression analysis revealed that AD was associated with chronic absenteeism overall (adjusted odds ratio, 1.42), and with more severe disease (aOR, 1.33 for mild to moderate disease; aOR, 2.00 for severe disease).

On the other hand, the researchers did not observe any statistical difference in chronic absenteeism among children with versus those without psoriasis (aOR, 1.26).

The researchers also found that parents of children with versus parents of children without AD had a higher prevalence of absenteeism from work (an aOR of 1.28 among fathers, P = .009; and an aOR of 1.24 among mothers, P = .003).

In other findings, chronic absenteeism among children with AD was associated with poor/near poor/low income (aOR, 4.61) and comorbid disease (aOR, 3.35 for depression and aOR, 3.83 for asthma).

The investigators recommend that clinicians screen for and aim to reduce school absenteeism and parental work absenteeism in children with AD.

“I typically ask ‘Has (child’s name) missed any school because of their eczema?’ and follow-up with ‘What about from asthma or allergies?’ ” Dr. Silverberg said. “If the parent’s answer is yes to the first question, then I follow-up with more open-ended probing questions to understand why. Is it from all the doctor visits? Not sleeping well? Severe itch or pain? Poor sleep? Feeling sad or depressed? An answer of yes to each of these would prompt a potentially different treatment decision.”

The discovery of any novel disease or condition means a steep learning curve as physicians must develop protocols for diagnosis, management, and follow-up on the fly in the midst of admitting and treating patients. Medical society task forces and committees often release interim guidance during the learning process, but each institution ultimately has to determine what works for them based on their resources, clinical experience, and patient population.

But when the novel condition demands the involvement of multiple different specialties, the challenge of management grows even more complex – as does follow-up after patients are discharged. Such has been the story with multisystem inflammatory syndrome in children (MIS-C), a complication of COVID-19 that shares some features with Kawasaki disease.

The similarities to Kawasaki provided physicians a place to start in developing appropriate treatment regimens and involved a similar interdisciplinary team from, at the least, cardiology and rheumatology, plus infectious disease since MIS-C results from COVID-19.

“It literally has it in the name – multisystem essentially hints that there are multiple specialties involved, multiple hands in the pot trying to manage the kids, and so each specialty has their own kind of unique role in the patient’s care even on the outpatient side,” said Samina S. Bhumbra, MD, an infectious disease pediatrician at Riley Hospital for Children and assistant professor of clinical pediatrics at Indiana University in Indianapolis. “This isn’t a disease that falls under one specialty.”

Determining a follow-up regimen

Even before determining how to coordinate appointments, hospitals had to decide what follow-up itself should be.

“How long do we follow these patients and how often do we follow them?” said Melissa S. Oliver, MD, a rheumatologist at Riley and assistant professor of clinical pediatrics at Indiana University.

“We’re seeing that a lot of our patients rapidly respond when they get appropriate therapy, but we don’t know about long-term outcomes yet. We’re all still learning.”

At Children’s Hospital of Philadelphia, infectious disease follows up 4-6 weeks post discharge. The cardiology division came up with a follow-up plan that has evolved over time, said Matthew Elias, MD, an attending cardiologist at CHOP’s Cardiac Center and clinical assistant professor of pediatrics at the University of Pennsylvania, Philadelphia.

The dedicated clinic model

The two challenges Riley needed to address were the lack of a clear consensus on what MIS-C follow-up should look like and the need for continuity of care, Dr. Serrano said.

Regular discussion in departmental meetings at Riley “progressed from how do we take care of them and what treatments do we give them to how do we follow them and manage them in outpatient,” Dr. Oliver said. In the inpatient setting, they had an interdisciplinary team, but how could they maintain that for outpatients without overwhelming the families?

“I think the main challenge is for the families to identify who is leading the care for them,” said Martha M. Rodriguez, MD, a rheumatologist at Riley and assistant professor of clinical pediatrics at Indiana University. That sometimes led to families picking which follow-up appointments they would attend and which they would skip if they could not make them all – and sometimes they skipped the more important ones. “They would go to the appointment with me and then miss the cardiology appointments and the echocardiogram, which was more important to follow any abnormalities in the heart,” Dr. Rodriguez said.

After trying to coordinate separate follow-up appointments for months, Riley ultimately decided to form a dedicated clinic for MIS-C follow-up – a “one-stop shop” single appointment at each follow-up, Dr. Bhumbra said, that covers labs, EKG, echocardiogram, and any other necessary tests.

“Our goal with the clinic is to make life easier for the families and to be able to coordinate the appointments,” Dr. Rodriguez said. “They will be able to see the three of us, and it would be easier for us to communicate with each other about their plan.”

The clinic began Feb. 11 and occurs twice a month. Though it’s just begun, Dr. Oliver said the first clinic went well, and it’s helping them figure out the role each specialty needs to play in follow-up care.

“For us with rheumatology, after lab values have returned to normal and they’re off steroids, sometimes we think there isn’t much more we can contribute to,” she said. And then there are the patients who didn’t see any rheumatologists while inpatients.

“That’s what we’re trying to figure out as well,” Dr. Oliver said. “Should we be seeing every single kid regardless of whether we were involved in their inpatient [stay] or only seeing the ones we’ve seen?” She expects the coming months will help them work that out.

Texas Children’s Hospital in Houston also uses a dedicated clinic, but they set it up before the first MIS-C patient came through the doors, said Sara Kristen Sexson Tejtel, MD, a pediatric cardiologist at Texas Children’s. The hospital already has other types of multidisciplinary clinics, and they anticipated the challenge of getting families to come to too many appointments in a short period of time.

Separate but coordinated appointments

A dedicated clinic isn’t the answer for all institutions, however. At Children’s Hospital of Philadelphia, the size of the networks and all its satellites made a one-stop shop impractical.

“We talked about a consolidated clinic early on, when MIS-C was first emerging and all our groups were collaborating and coming up with our inpatient and outpatient care pathways,” said Sanjeev K. Swami, MD, an infectious disease pediatrician at CHOP and associate professor of clinical pediatrics at the University of Pennsylvania. But timing varies on when each specialist wants to see the families return, and existing clinic schedules and locations varied too much.

Looking ahead

The biggest question that still looms is what happens to these children, if anything, down the line.

“What was unique about this was this was a new disease we were all learning about together with no baseline,” Dr. Swami said. “None of us had ever seen this condition before.”

So far, the prognosis for the vast majority of children is good. “Most of these kids survive, most of them are doing well, and they almost all recover,” Dr. Serrano said. Labs tend to normalize by 6 weeks post discharge, if not much earlier, and not much cardiac involvement is showing up at later follow-ups. But not even a year has passed, so there’s plenty to learn. “We don’t know if there’s long-term risk. I would not be surprised if 20 years down the road we’re finding out things about this that we had no idea” about, Dr. Serrano said. “Everybody wants answers, and nobody has any, and the answers we have may end up being wrong. That’s how it goes when you’re dealing with something you’ve never seen.”

Research underway will ideally begin providing those answers soon. CHOP is a participating site in an NIH-NHLBI–sponsored study, called COVID MUSIC, that is tracking long-term outcomes for MIS-C at 30 centers across the United States and Canada for 5 years.

“That will really definitely be helpful in answering some of the questions about long-term outcomes,” Dr. Elias said. “We hope this is going to be a transient issue and that patients won’t have any long-term manifestations, but we don’t know that yet.”

Meanwhile, one benefit that has come out of the pandemic is strong collaboration, Dr. Bhumbra said.

“The biggest thing we’re all eagerly waiting and hoping for is standard guidelines on how best to follow-up on these kids, but I know that’s a ways away,” Dr. Bhumbra said. So for now, each institution is doing what it can to develop protocols that they feel best serve the patients’ needs, such as Riley’s new dedicated MIS-C clinic. “It takes a village to take care of these kids, and MIS-C has proven that having a clinic with all three specialties at one clinic is going to be great for the families.”

Dr. Fox serves on a committee for Pfizer unrelated to MIS-C. No other doctors interviewed for this story had relevant conflicts of interest to disclose.

“That will really definitely be helpful in answering some of the questions about long-term outcomes,” Dr. Elias said. “We hope this is going to be a transient issue and that patients won’t have any long-term manifestations, but we don’t know that yet.”

Meanwhile, one benefit that has come out of the pandemic is strong collaboration, Dr. Bhumbra said.

“The biggest thing we’re all eagerly waiting and hoping for is standard guidelines on how best to follow-up on these kids, but I know that’s a ways away,” Dr. Bhumbra said. So for now, each institution is doing what it can to develop protocols that they feel best serve the patients’ needs, such as Riley’s new dedicated MIS-C clinic. “It takes a village to take care of these kids, and MIS-C has proven that having a clinic with all three specialties at one clinic is going to be great for the families.”

Dr. Fox serves on a committee for Pfizer unrelated to MIS-C. No other doctors interviewed for this story had relevant conflicts of interest to disclose.

Vaping cannabis significantly increased the risk of respiratory symptoms in adolescents, according to findings of a study based on a national sample of teens.

Most studies of electronic nicotine delivery systems (ENDS) use in teens have not addressed cannabis vaping, although e-cigarette– or vaping product use–associated lung injury (EVALI) has been predominately associated with cannabis products, wrote Carol J. Boyd, PhD, of the University of Michigan School of Nursing, Ann Arbor, and colleagues.

“At this time, relatively little is known about the population-level health consequences of adolescents’ use of ENDS, including use with cannabis and controlling for a history of asthma,” they said.

In a study published in the Journal of Adolescent Health, the researchers identified 14,798 adolescents aged 12-17 years using Wave 4 data from the Population Assessment of Tobacco and Health Study. Of these, 17.6% had a baseline asthma diagnosis, 8.9% reported ever using cannabis in ENDS, and 4.7% reported any cannabis use. In addition, 4.2% reported current e-cigarette use, 3.1% reported current cigarette use, 51% were male, and 69.2% were white.
 

Any cannabis vaping makes impact

In a fully-adjusted model, teens who had ever vaped cannabis had higher odds of five respiratory symptoms in the past year, compared with those with no history of cannabis vaping: wheezing or whistling in the chest (adjusted odds ratio, 1.81); sleep disturbed by wheezing or whistling (AOR, 1.71); speech limited because of wheezing (AOR, 1.96); wheezy during and after exercise (AOR, 1.33), and a dry cough at night independent of a cold or chest infection (AOR, 1.26).

Neither e-cigarettes nor cigarettes were significantly associated with any of these five respiratory symptoms in the fully adjusted models. In addition, “past 30-day use of cigarettes, e-cigarettes and cannabis use were associated with some respiratory symptoms in bivariate analyses but not in the adjusted models,” the researchers noted. In addition, the associations of an asthma diagnosis and respiratory symptoms had greater magnitudes than either cigarette, e-cigarette, and cannabis use or vaping cannabis with ENDS.

The study findings were limited by several factors including the inherent limitations of secondary database analysis, the researchers noted. “Another limitation is that co-use of cannabis and tobacco/nicotine was not assessed and, in the future, should be examined: Researchers have found that co-use is related to EVALI symptoms among young adults,” they said.

However, the study is the first known to include ENDS product use and respiratory symptoms while accounting for baseline asthma, and an asthma diagnosis was even more strongly associated with all five respiratory symptoms, the researchers said.

The results suggest that “the inhalation of cannabis via vaping is associated with some pulmonary irritation and symptoms of lung diseases (both known and unknown),” that may be predictive of later EVALI, they concluded.
 

Product details aid in diagnosis

“As we continue to see patients presenting with EVALI in pediatric hospitals, it is important for us to identify if there are specific products (or categories) that are more likely to cause it,” said Brandon Seay, MD, FCCP, a pediatric pulmonologist and sleep specialist at Children’s Healthcare of Atlanta, in an interview. “When we are trying to diagnose EVALI, we should be asking appropriate questions about exposures to specific products to get the best answers. If we simply ask ‘Are you smoking e-cigarettes?’ the patient may not [equate] e-cigarette smoking to vaping cannabis products,” he said. 

Dr. Seay said he was not surprised by the study findings. “A lot of the patients I see with EVALI have reported vaping THC products, and most of them also report that the products were mixed by a friend or an individual instead of being a commercially produced product,” he noted. “This is not surprising, as THC is still illegal in most states and there would not be any commercially available products,” he said. “The mixing of these products by individuals increases the risk of ingredients being more toxic or irritating to the lungs,” Dr. Seay added. “This does highlight the need for more regulation of vaping products. As more states legalize marijuana, more of these products will become available, which will provide an opportunity for increased regulation, he said. 

The take-home message for clinicians is to seek specific details from their young patients, Dr. Seay emphasized. “When we are educating our patients on the dangers of vaping/e-cigarettes, we need to make sure we are asking specifically which products they are using and know the terminology,” he said. “The use of THC-containing products will be increasing across the country with more legalization, so we need to keep ourselves apprised of the different risks between THC- and nicotine-containing devices,” he added.  

As for additional research, it would be interesting to know whether patients were asked where they had gotten their products (commercially available products vs. those mixed by individuals) and explore any difference between the two, said Dr. Seay. “Also, as these products are relatively new to the market, compared to cigarettes, data on the longitudinal effects of vaping (nicotine and THC) over a long period of time, compared to traditional combustible cigarettes, will be needed,” he said.

The study was funded by grants from the National Institutes of Health, National Institute on Drug Abuse, and National Cancer Institute. The researchers had no financial conflicts to disclose.

Dr. Seay had no financial disclosures, but serves as a member of the CHEST Physician editorial board.

The numbers are in to back up two policies designed to restrict the spread of the COVID-19 pandemic.

Researchers at the Centers for Disease Control and Prevention) found that when states lifted restrictions on dining on premises at restaurants, rates of daily COVID-19 cases jumped 41-100 days later. COVID-19-related deaths also increased significantly after 60 days.

On the other hand, the same report demonstrates that state mask mandates slowed the spread of SARS-CoV-2 within a few weeks.

The study was published online March 5 in the CDC Morbidity and Mortality Weekly Report.

The investigators did not distinguish between outdoor and indoor restaurant dining. But they did compare COVID-19 case and death rates before and after most states banned restaurants from serving patrons on-premises in March and April 2020.

They found, for example, that COVID-19 daily cases increased by 0.9% at 41-60 days after on-premise dining was permitted. Similarly, rates jumped by 1.2% at 61-80 days, and 1.1% at 81-100 days after the restaurant restrictions were lifted. 

The differences were statistically significant, with P values of .02, <.01, and .04, respectively.

COVID-19–related death rates did not increase significantly at first – but did jump 2.2% between 61 and 80 days after the return of on-premises dining, for example. Deaths also increased by 3% at 81-100 days.

Both these differences were statistically significant (P < .01).

This is not the first report where the CDC announced reservations about in-person dining. In September 2020, CDC investigators implicated the inability to wear a mask while eating and drinking as likely contributing to the heightened risk.
 

Masks make a difference

The CDC report also provided more evidence to back mask-wearing policies for public spaces. Between March 1 and Dec. 31, 2020, 74% of U.S. counties issued mask mandates.

Investigators found that these policies had a more immediate effect, reducing daily COVID-19 cases by 0.5% in the first 20 days. Mask mandates likewise were linked to daily cases dropping 1.1% between 21 and 40 days, 1.5% between 41 and 60 days, 1.7% between 61 and 80 days, and 1.8% between 81 and 100 days.

These decreases in daily COVID-19 cases were statistically significant (P < .01) compared with a reference period before March 1, 2020.

The CDC also linked mask mandates to lower mortality. For example, these state policies were associated with 0.7% fewer deaths at 1-20 days post implementation. The effect increased thereafter – 1.0% drop at 21-40 days, 1.4% decrease at 41-60 days, 1.6% drop between 61 and 80 days, and 1.9% fewer deaths between 81 and 100 days.

The decrease in deaths was statistically significant at 1-20 days after the mask mandate (P = .03), as well as during the other periods (each P < .01) compared with the reference period.

CDC Director Rochelle Walensky, MD, reacted to the new findings at a White House press briefing. She cited how increases in COVID-19 cases and death rates “slowed significantly within 20 days of putting mask mandates into place. This is why I’m asking you to double down on prevention measures.

“We have seen this movie before,” Dr. Walensky added. “When prevention measures like mask-wearing mandates are lifted, cases go up.”

Recently, multiple states have announced plans to roll back restrictions related to the pandemic, including mask mandates, which prompted warnings from some public health officials.

These are not the first CDC data to show that mask mandates make a difference.

In February 2021, for example, the agency pointed out that state-wide mask mandates reduced COVID-19 hospitalizations by 5.5% among adults 18-64 years old within 3 weeks of implementation.

Restrictions regarding on-premises restaurant dining and implementation of state-wide mask mandates are two tactics within a more comprehensive CDC strategy to reduce the spread of SARS-CoV-2. The researchers note that “such efforts are increasingly important given the emergence of highly transmissible SARS-CoV-2 variants in the United States.”

The researchers have disclosed no relevant financial relationships.

A bidirectional relationship between sleep and immunity helps explain why patients with atopic dermatitis (AD) often complain of difficulty sleeping.

According to Phyllis C. Zee, MD, PhD, proinflammatory cytokines influence neural processes that affect sleep and circadian rhythm. “It’s almost like when you’re most vulnerable, when you’re sleeping, the immune system is kind of poised for attack,” Dr. Zee, chief of the division of sleep medicine at Northwestern University, Chicago, said at the Revolutionizing Atopic Dermatitis symposium. “This is normal, and perhaps in some of these inflammatory disorders, it’s gone a little haywire.”

Circulation of interleukins and cytokines are high in the morning, become lower in the afternoon, and then get higher again in the evening hours and into the night during sleep, she continued. “Whereas if you look at something like blood flow, it increases on a diurnal basis,” she said. “It’s higher during the day and a little bit lower during the mid-day, and a little bit higher during the evening. That parallels changes in the sebum production of the skin and the transepidermal water loss, which has been implicated in some of the symptoms of AD. What’s curious about this is that the transdermal/epidermal water loss is really highest during the sleep period. Some of this is sleep gated, but some of this is circadian gated as well. There’s a bidirectional relationship between sleep and immunity.”

Disturbance of sleep can have multiple consequences. It can activate the hypothalamic-pituitary-adrenal axis through autonomic activation, increase brain metabolic activity, trigger mood disturbances and cognitive impairment, and cause daytime sleepiness and health consequences that affect cardiometabolic and immunologic health.

One study conducted by Anna B. Fishbein, MD, Dr. Zee, and colleagues at Northwestern examined the effects of sleep duration and sleep disruption and movements in 38 children with and without moderate to severe AD. It found that children with AD get about 1 hour less of sleep per night overall, compared with age-matched healthy controls. “It’s not so much difficulty falling asleep, but more difficulty staying asleep as determined by wake after sleep onset,” said Dr. Zee, who is also a professor of neurology at Northwestern.

A study of 34,613 adults who participated in the 2012 National Health and Nutrition Examination Survey found that eczema increased the odds of fatigue (odds ratio, 2.97), daytime sleepiness (OR, 2.66), and regular insomnia (OR, 2.36).

“Very importantly, it predicted poor health,” said Dr. Zee, who was one of the study’s coauthors. “This gives us an opportunity to think about how we can improve sleep to improve outcomes.”

Dr. Zee advises dermatologists and primary care clinicians to ask patients with AD about their sleep health by using a screening tool such as the self-reported STOP questionnaire, which consists of the following questions: “Do you snore loudly?” “Do you often feel tired, fatigued, or sleepy during daytime?” “Has anyone observed you stop breathing during your sleep?” “Do you have or are you being treated for high blood pressure?”

Other clinical indicators of a sleep disorder, such as obstructive sleep apnea (OSA), include having a neck circumference of 17 inches or greater in men and 16 inches or greater in women. “You want to also do a brief upper-airway examination, the Mallampati classification where you say to the patient, ‘open your mouth, don’t stick your mouth out too much,’ and you look at how crowded the upper airway is,” Dr. Zee said . “Someone with a Mallampati score of 3 has a very high risk of having sleep apnea.”

She also recommends asking patients with AD if they have difficulty falling asleep or staying asleep 3 or more nights per week, and about the frequency and duration of awakenings. “Maybe they have insomnia as a disorder,” she said. “If they have trouble falling asleep, maybe they have a circadian rhythm disorder. You want to ask about snoring, choking, and stop breathing episodes, because those are symptoms of sleep apnea. You want to ask about itch, uncomfortable sensations in the limbs during sleep or while trying to get to sleep, because that may be something like restless legs syndrome. Sleep disorder assessment is important because it impair daytime function, cognition, attention, and disruptive behavior, especially in children.”

For the management of insomnia, try behavioral approaches first. “You don’t want to try medications from the get-go,” Dr. Zee advised. Techniques include sleep hygiene and stimulus control therapy, “to make the bedroom a safe place to sleep. Lower the temperature a little bit and get rid of the allergens as much as possible. Relaxation and cognitive-behavioral therapy can also help. If you get a lot of light during the day, structure your physical activity, and watch what and when you eat.”

An OSA diagnosis requires evaluation of objective information from a sleep study. Common treatments of mild to moderate OSA include nasal continuous positive airway pressure and oral appliances.

According to Phyllis C. Zee, MD, PhD, proinflammatory cytokines influence neural processes that affect sleep and circadian rhythm. “It’s almost like when you’re most vulnerable, when you’re sleeping, the immune system is kind of poised for attack,” Dr. Zee, chief of the division of sleep medicine at Northwestern University, Chicago, said at the Revolutionizing Atopic Dermatitis symposium. “This is normal, and perhaps in some of these inflammatory disorders, it’s gone a little haywire.”

Circulation of interleukins and cytokines are high in the morning, become lower in the afternoon, and then get higher again in the evening hours and into the night during sleep, she continued. “Whereas if you look at something like blood flow, it increases on a diurnal basis,” she said. “It’s higher during the day and a little bit lower during the mid-day, and a little bit higher during the evening. That parallels changes in the sebum production of the skin and the transepidermal water loss, which has been implicated in some of the symptoms of AD. What’s curious about this is that the transdermal/epidermal water loss is really highest during the sleep period. Some of this is sleep gated, but some of this is circadian gated as well. There’s a bidirectional relationship between sleep and immunity.”

Disturbance of sleep can have multiple consequences. It can activate the hypothalamic-pituitary-adrenal axis through autonomic activation, increase brain metabolic activity, trigger mood disturbances and cognitive impairment, and cause daytime sleepiness and health consequences that affect cardiometabolic and immunologic health.

One study conducted by Anna B. Fishbein, MD, Dr. Zee, and colleagues at Northwestern examined the effects of sleep duration and sleep disruption and movements in 38 children with and without moderate to severe AD. It found that children with AD get about 1 hour less of sleep per night overall, compared with age-matched healthy controls. “It’s not so much difficulty falling asleep, but more difficulty staying asleep as determined by wake after sleep onset,” said Dr. Zee, who is also a professor of neurology at Northwestern.

A study of 34,613 adults who participated in the 2012 National Health and Nutrition Examination Survey found that eczema increased the odds of fatigue (odds ratio, 2.97), daytime sleepiness (OR, 2.66), and regular insomnia (OR, 2.36).

“Very importantly, it predicted poor health,” said Dr. Zee, who was one of the study’s coauthors. “This gives us an opportunity to think about how we can improve sleep to improve outcomes.”
