SAN DIEGO — Treatment with topical roflumilast, 0.05%, approved at a higher concentration for treating psoriasis, showed high levels of improvement in about a quarter of children aged 2-5 years with mild to moderate atopic dermatitis (AD), according to the results of a phase 3 study reported at the annual meeting of the American Academy of Dermatology.

Among patients treated with roflumilast cream, 0.05%, 25.4% reached the primary endpoint of “clear” or “almost clear” plus a two-grade improvement from baseline at week 4 vs 10.7% among those in the vehicle group (P < .0001) in a phase 3 randomized controlled trial of children. The findings were released in a late-breaker session at the meeting.

Roflumilast cream, 0.3% (Zoryve), is approved by the Food and Drug Administration (FDA) for treating psoriasis in patients 6 years and older, and lower doses are being evaluated for AD: 0.15% for adults and children ages 6 and older, and 0.05% for ages 2-5. Roflumilast is a phosphodiesterase-4 inhibitor. In 2023, the FDA accepted a supplemental drug application from the manufacturer, Arcutis, for roflumilast, 0.15%, for treating AD in patients ages 6 and older, based on the results from two recently published phase 3 trials, INTEGUMENT-1 and INTEGUMENT-2.

The study of younger children, INTEGUMENT-PED, recruited 652 patients aged 2-5 with mild to moderate AD, with a Validated Investigator Global Assessment scale for AD (vlGA-AD) score of 2 or 3, a mean body surface area of 22% overall (range, 3%-82%), and an Eczema Area and Severity Index (EASI) score of at least 5. Of the patients enrolled, 437 were assigned to 0.05% roflumilast cream, applied once a day for 4 weeks (mean age, 3.3 years; 51.6% male; 67.4% White; 15.6% Black; 8.5% Asian; 8.5% other or more than one race; 80.5% not Latino/Hispanic). The remaining 215 children were assigned to vehicle cream and had similar characteristics.

About 52% of the patients in both groups had an inadequate response, intolerance, or contraindications to topical corticosteroids (and about 17% for topical calcineurin inhibitors and about 9% for crisaborole).

The proportions of patients who reached “clear” (0) or “almost clear” (1) on the vlGA-AD scale were 35.4% and 14.6%, respectively, at week 4 (P < .0001) for roflumilast and vehicle, respectively, according to the lead author of the study, Lawrence M. Eichenfield, MD, professor of dermatology and pediatrics at the University of California, San Diego, who presented the results at the meeting. In addition, 39.4% and 20.6% achieved an EASI-75 (a secondary endpoint), respectively (P < .0001), and itch also improved within 24 hours of starting treatment.

With regard to safety, 29.7% of patients taking roflumilast had treatment-emergent adverse effects (including upper respiratory tract infections in 4.1%) vs 21.9% of those in the vehicle arm (including upper respiratory tract infections in 1.4%). Reports of pain at the administration site were low (1.6% for roflumilast vs 1.9% for vehicle). Only one patient, a 2-year-old girl, had a treatment-emergent serious adverse event. The child, who was in the roflumilast group, had cellulitis involving noneczematous skin and was treated with antibiotics in the hospital for 3 days. The event was not attributed to roflumilast, which was stopped for 5 days, according to Dr. Eichenfield.

In an interview, Fairfield, Connecticut–based dermatologist Brittany Craiglow, MD, who was not involved in the study, said topical roflumilast would be an “important” new treatment because there are still few nonsteroidal options for the treatment of AD in children under 12. “The excellent local tolerability combined with early improvements in itch and skin clearance will make this a particularly attractive option, if approved,” she said.

Dr. Eichenfield disclosed multiple relationships with various drugmakers. He and several other study authors are investigators and/or consultants for Arcutis and received grants/research funding and/or honoraria. Two authors are Arcutis employees. Other disclosure information for the authors was not immediately available. Dr. Craiglow had no disclosures.

FAIRFAX, VIRGINIA — Nearly 30 years ago, in a 1995 paper, the British physician-epidemiologist David Barker, MD, PhD, wrote about his fetal origins hypothesis — the idea that programs to address fetal undernutrition and low birth weight produced later coronary heart disease (BMJ 1995;311:171-4).

His hypothesis and subsequent research led to the concept of adult diseases of fetal origins, which today extends beyond low birth weight and implicates the in utero environment as a significant determinant of risk for adverse childhood and adult metabolic outcomes and for major chronic diseases, including diabetes and obesity. Studies have shown that the offspring of pregnant mothers with diabetes have a higher risk of developing obesity and diabetes themselves.

“It’s a whole discipline [of research],” E. Albert Reece, MD, PhD, MBA, of the University of Maryland School of Medicine (UMSOM), said in an interview. “But what we’ve never quite understood is the ‘how’ and ‘why’? What are the mechanisms driving the fetal origins of such adverse outcomes in offspring?

At the biennial meeting of the Diabetes in Pregnancy Study Group of North America (DPSG), investigators described studies underway that are digging deeper into the associations between the intrauterine milieu and longer-term offspring health — and that are searching for biological and molecular processes that may be involved.

The studies are like “branches of the Barker hypothesis,” said Dr. Reece, former dean of UMSOM and current director of the UMSOM Center for Advanced Research Training and Innovation, who co-organized the DPSG meeting. “They’re taking the hypothesis and dissecting it by asking, for instance, it is possible that transgenerational obesity may align with the Barker hypothesis? Is it possible that it involves epigenetics regulation? Could we find biomarkers?”

The need for a better understanding of the fetal origins framework — and its subsequent transgenerational impact — is urgent. From 2000 to 2018, the prevalence of childhood obesity increased from 14.7% to 19.2% (a 31% increase) and the prevalence of severe childhood obesity rose from 3.9% to 6.1% (a 56% increase), according to data from the U.S. National Health and Nutrition Examination Survey (Obes Facts. 2022;15[4]:560-9).

Children aged 2-5 years have had an especially sharp increase in obesity (Pediatrics 2018;141[3]:e20173459), Christine Wey Hockett, PhD, of the University of South Dakota School of Medicine, said at the DPSG meeting (Figure 1).

Deeper Dives Into Associations, Potential Mechanisms

The EPOCH prospective cohort study with which Dr. Hockett was involved gave her a front-seat view of the transgenerational adverse effects of in utero exposure to hyperglycemia. The study recruited ethnically diverse maternal/child dyads from the Kaiser Permanente of Colorado perinatal database from 1992 to 2002 and assessed 418 offspring at two points — a mean age of 10.5 years and 16.5 years — for fasting blood glucose, adiposity, and diet and physical activity. The second visit also involved an oral glucose tolerance test.

The 77 offspring who had been exposed in utero to GDM had a homeostatic model assessment of insulin resistance (HOMA-IR) that was 18% higher, a 19% lower Matsuda index, and a 9% greater HOMA of β-cell function (HOMA-β) than the 341 offspring whose mothers did not have diabetes. Each 5-kg/m² increase in prepregnancy body mass index predicted increased insulin resistance, but there was no combined effect of both maternal obesity and diabetes in utero.

Exposed offspring had a higher BMI and increased adiposity, but when BMI was controlled for in the analysis of metabolic outcomes, maternal diabetes was still associated with 12% higher HOMA-IR and a 17% lower Matsuda index. “So [the metabolic outcomes] are a direct effect of maternal diabetes,” Dr. Hockett said at the DPSG meeting, noting the fetal overnutrition hypothesis in which maternal glucose, but not maternal insulin, freely passes through the placenta, promoting growth and adiposity in the fetus.

[The EPOCH results on metabolic outcomes and offspring adiposity were published in 2017 and 2019, respectively (Diabet Med. 2017;34:1392-9; Diabetologia. 2019;62:2017-24). In 2020, EPOCH researchers reported sex-specific effects on cardiovascular outcomes, with GDM exposure associated with higher total and LDL cholesterol in girls and higher systolic blood pressure in boys (Pediatr Obes. 2020;15[5]:e12611).]

Now, a new longitudinal cohort study underway in Phoenix, is taking a deeper dive, trying to pinpoint what exactly influences childhood obesity and metabolic risk by following Hispanic and American Indian maternal/child dyads from pregnancy until 18 years postpartum. Researchers are looking not only at associations between maternal risk factors (pregnancy BMI, gestational weight gain, and diabetes in pregnancy) and offspring BMI, adiposity, and growth patterns, but also how various factors during pregnancy — clinical, genetic, lifestyle, biochemical — ”may mediate the associations,” said lead investigator Madhumita Sinha, MD.

“We need a better understanding at the molecular level of the biological processes that lead to obesity in children and that cause metabolic dysfunction,” said Dr. Sinha, who heads the Diabetes Epidemiology and Clinical Research Section of the of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) branch in Phoenix.

The populations being enrolled in the ETCHED study (for Early Tracking of Childhood Health Determinants) are at especially high risk of childhood obesity and metabolic dysfunction. Research conducted decades ago by the NIDDK in Phoenix showed that approximately 50% of Pima Indian children from diabetic pregnancies develop type 2 diabetes by age 25 (N Engl J Med. 1983;308:242-5). Years later, to tease out possible genetic factors, researchers compared siblings born before and after their mother was found to have type 2 diabetes, and found significantly higher rates of diabetes in those born after the mother’s diagnosis, affirming the role of in utero toxicity (Diabetes 2000;49:2208-11).

In the new study, the researchers will look at adipokines and inflammatory biomarkers in the mothers and offspring in addition to traditional anthropometric and glycemic measures. They’ll analyze placental tissue, breast milk, and the gut microbiome longitudinally, and they’ll lean heavily on genomics/epigenomics, proteomics, and metabolomics. “There’s potential,” Dr. Sinha said, “to develop a more accurate predictive and prognostic model of childhood obesity.”

The researchers also will study the role of family, socioeconomics, and environmental factors in influencing child growth patterns and they’ll look at neurodevelopment in infancy and childhood. As of October 2023, almost 80 pregnant women, most with obesity and almost one-third with type 2 diabetes, had enrolled in the study. Over the next several years, the study aims to enroll 750 dyads.
 

The Timing of In Utero Exposure

Shelley Ehrlich, MD, ScD, MPH, of the University of Cincinnati and Cincinnati Children’s Hospital Medical Center, is aiming, meanwhile, to learn how the timing of in utero exposure to hyperglycemia predicts specific metabolic and cardiovascular morbidities in the adult offspring of diabetic mothers.

“While we know that exposure to maternal diabetes, regardless of type, increases the risk of obesity, insulin resistance, diabetes, renal compromise, and cardiovascular disease in the offspring, there is little known about the level and timing of hyperglycemic exposure during fetal development that triggers these adverse outcomes,” said Dr. Ehrlich. A goal, she said, is to identify gestational profiles that predict phenotypes of offspring at risk for morbidity in later life.

She and other investigators with the TEAM (Transgenerational Effect on Adult Morbidity) study have recruited over 170 offspring of mothers who participated in the Diabetes in Pregnancy Program Project Grant (PPG) at the University of Cincinnati Medical Center from 1978 to 1995 — a landmark study that demonstrated the effect of strict glucose control in reducing major congenital malformations.

The women in the PPG study had frequent glucose monitoring (up to 6-8 times a day) throughout their pregnancies, and now, their recruited offspring, who are up to 43 years of age, are being assessed for obesity, diabetes/metabolic health, cardiovascular disease/cardiac and peripheral vascular structure and function, and other outcomes including those that may be amenable to secondary prevention (J Diabetes Res. Nov 1;2021:6590431).

Preliminary findings from over 170 offspring recruited between 2017 and 2022 suggest that in utero exposure to dysglycemia (as measured by standard deviations of glycohemoglobin) in the third trimester appears to increase the risk of morbid obesity in adulthood, while exposure to dysglycemia in the first trimester increases the risk of impaired glucose tolerance. The risk of B-cell dysfunction, meanwhile, appears to be linked to dysglycemia in the first and third trimesters — particularly the first — Dr. Ehrlich reported.

Cognitive outcomes in offspring have also been assessed and here it appears that dysglycemia in the third trimester is linked to worse scores on the Wechsler Abbreviated Scale of Intelligence (WASI-II), said Katherine Bowers, PhD, MPH, a TEAM study coinvestigator, also of Cincinnati Children’s Hospital Medical Center.

“We’ve already observed [an association between] diabetes in pregnancy and cognition in early childhood and through adolescence, but [the question has been] does this association persist into adulthood?” she said.

Preliminary analyses of 104 offspring show no statistically significant associations between maternal dysglycemia in the first or second trimesters and offspring cognition, but “consistent inverse associations between maternal glycohemoglobin in the third trimester across two [WASI-II] subscales and composite measures of cognition,” Dr. Bowers said.

Their analysis adjusted for a variety of factors, including maternal age, prepregnancy and first trimester BMI, race, family history of diabetes, and diabetes severity/macrovascular complications.
 

Back In The Laboratory

At the other end of the research spectrum, basic research scientists are also investigating the mechanisms and sequelae of in utero hyperglycemia and other injuries, including congenital malformations, placental adaptive responses and fetal programming. Researchers are asking, for instance, what does placental metabolic reprogramming entail? What role do placental extracellular vesicles play in GDM? Can we alter the in utero environment and thus improve the short and long-term fetal/infant outcomes?

Animal research done at the UMSOM Center for Birth Defects Research, led by Dr. Reece and Peixin Yang, PhD, suggests that “a good portion of in utero injury is due to epigenetics,” Dr. Reece said in the interview. “We’ve shown that under conditions of hyperglycemia, for example, genetic regulation and genetic function can be altered.”

Through in vivo research, they have also shown that antioxidants or membrane stabilizers such as arachidonic acid or myo-inositol, or experimental inhibitors to certain pro-apoptotic intermediates, can individually or collectively result in reduced malformations. “It is highly likely that understanding the biological impact of various altered in utero environments, and then modifying or reversing those environments, will result in short and long-term outcome improvements similar to those shown with congenital malformations,” Dr. Reece said.

FAIRFAX, VIRGINIA — Nearly 30 years ago, in a 1995 paper, the British physician-epidemiologist David Barker, MD, PhD, wrote about his fetal origins hypothesis — the idea that programs to address fetal undernutrition and low birth weight produced later coronary heart disease (BMJ 1995;311:171-4).

Cognitive outcomes in offspring have also been assessed and here it appears that dysglycemia in the third trimester is linked to worse scores on the Wechsler Abbreviated Scale of Intelligence (WASI-II), said Katherine Bowers, PhD, MPH, a TEAM study coinvestigator, also of Cincinnati Children’s Hospital Medical Center.

“We’ve already observed [an association between] diabetes in pregnancy and cognition in early childhood and through adolescence, but [the question has been] does this association persist into adulthood?” she said.

Preliminary analyses of 104 offspring show no statistically significant associations between maternal dysglycemia in the first or second trimesters and offspring cognition, but “consistent inverse associations between maternal glycohemoglobin in the third trimester across two [WASI-II] subscales and composite measures of cognition,” Dr. Bowers said.

Their analysis adjusted for a variety of factors, including maternal age, prepregnancy and first trimester BMI, race, family history of diabetes, and diabetes severity/macrovascular complications.
 

Back In The Laboratory

At the other end of the research spectrum, basic research scientists are also investigating the mechanisms and sequelae of in utero hyperglycemia and other injuries, including congenital malformations, placental adaptive responses and fetal programming. Researchers are asking, for instance, what does placental metabolic reprogramming entail? What role do placental extracellular vesicles play in GDM? Can we alter the in utero environment and thus improve the short and long-term fetal/infant outcomes?

Animal research done at the UMSOM Center for Birth Defects Research, led by Dr. Reece and Peixin Yang, PhD, suggests that “a good portion of in utero injury is due to epigenetics,” Dr. Reece said in the interview. “We’ve shown that under conditions of hyperglycemia, for example, genetic regulation and genetic function can be altered.”

Through in vivo research, they have also shown that antioxidants or membrane stabilizers such as arachidonic acid or myo-inositol, or experimental inhibitors to certain pro-apoptotic intermediates, can individually or collectively result in reduced malformations. “It is highly likely that understanding the biological impact of various altered in utero environments, and then modifying or reversing those environments, will result in short and long-term outcome improvements similar to those shown with congenital malformations,” Dr. Reece said.

FAIRFAX, VIRGINIA — Nearly 30 years ago, in a 1995 paper, the British physician-epidemiologist David Barker, MD, PhD, wrote about his fetal origins hypothesis — the idea that programs to address fetal undernutrition and low birth weight produced later coronary heart disease (BMJ 1995;311:171-4).

His hypothesis and subsequent research led to the concept of adult diseases of fetal origins, which today extends beyond low birth weight and implicates the in utero environment as a significant determinant of risk for adverse childhood and adult metabolic outcomes and for major chronic diseases, including diabetes and obesity. Studies have shown that the offspring of pregnant mothers with diabetes have a higher risk of developing obesity and diabetes themselves.

“It’s a whole discipline [of research],” E. Albert Reece, MD, PhD, MBA, of the University of Maryland School of Medicine (UMSOM), said in an interview. “But what we’ve never quite understood is the ‘how’ and ‘why’? What are the mechanisms driving the fetal origins of such adverse outcomes in offspring?

At the biennial meeting of the Diabetes in Pregnancy Study Group of North America (DPSG), investigators described studies underway that are digging deeper into the associations between the intrauterine milieu and longer-term offspring health — and that are searching for biological and molecular processes that may be involved.

The studies are like “branches of the Barker hypothesis,” said Dr. Reece, former dean of UMSOM and current director of the UMSOM Center for Advanced Research Training and Innovation, who co-organized the DPSG meeting. “They’re taking the hypothesis and dissecting it by asking, for instance, it is possible that transgenerational obesity may align with the Barker hypothesis? Is it possible that it involves epigenetics regulation? Could we find biomarkers?”

The need for a better understanding of the fetal origins framework — and its subsequent transgenerational impact — is urgent. From 2000 to 2018, the prevalence of childhood obesity increased from 14.7% to 19.2% (a 31% increase) and the prevalence of severe childhood obesity rose from 3.9% to 6.1% (a 56% increase), according to data from the U.S. National Health and Nutrition Examination Survey (Obes Facts. 2022;15[4]:560-9).

Children aged 2-5 years have had an especially sharp increase in obesity (Pediatrics 2018;141[3]:e20173459), Christine Wey Hockett, PhD, of the University of South Dakota School of Medicine, said at the DPSG meeting (Figure 1).

Deeper Dives Into Associations, Potential Mechanisms

The EPOCH prospective cohort study with which Dr. Hockett was involved gave her a front-seat view of the transgenerational adverse effects of in utero exposure to hyperglycemia. The study recruited ethnically diverse maternal/child dyads from the Kaiser Permanente of Colorado perinatal database from 1992 to 2002 and assessed 418 offspring at two points — a mean age of 10.5 years and 16.5 years — for fasting blood glucose, adiposity, and diet and physical activity. The second visit also involved an oral glucose tolerance test.

The 77 offspring who had been exposed in utero to GDM had a homeostatic model assessment of insulin resistance (HOMA-IR) that was 18% higher, a 19% lower Matsuda index, and a 9% greater HOMA of β-cell function (HOMA-β) than the 341 offspring whose mothers did not have diabetes. Each 5-kg/m² increase in prepregnancy body mass index predicted increased insulin resistance, but there was no combined effect of both maternal obesity and diabetes in utero.

Exposed offspring had a higher BMI and increased adiposity, but when BMI was controlled for in the analysis of metabolic outcomes, maternal diabetes was still associated with 12% higher HOMA-IR and a 17% lower Matsuda index. “So [the metabolic outcomes] are a direct effect of maternal diabetes,” Dr. Hockett said at the DPSG meeting, noting the fetal overnutrition hypothesis in which maternal glucose, but not maternal insulin, freely passes through the placenta, promoting growth and adiposity in the fetus.

[The EPOCH results on metabolic outcomes and offspring adiposity were published in 2017 and 2019, respectively (Diabet Med. 2017;34:1392-9; Diabetologia. 2019;62:2017-24). In 2020, EPOCH researchers reported sex-specific effects on cardiovascular outcomes, with GDM exposure associated with higher total and LDL cholesterol in girls and higher systolic blood pressure in boys (Pediatr Obes. 2020;15[5]:e12611).]

Now, a new longitudinal cohort study underway in Phoenix, is taking a deeper dive, trying to pinpoint what exactly influences childhood obesity and metabolic risk by following Hispanic and American Indian maternal/child dyads from pregnancy until 18 years postpartum. Researchers are looking not only at associations between maternal risk factors (pregnancy BMI, gestational weight gain, and diabetes in pregnancy) and offspring BMI, adiposity, and growth patterns, but also how various factors during pregnancy — clinical, genetic, lifestyle, biochemical — ”may mediate the associations,” said lead investigator Madhumita Sinha, MD.

“We need a better understanding at the molecular level of the biological processes that lead to obesity in children and that cause metabolic dysfunction,” said Dr. Sinha, who heads the Diabetes Epidemiology and Clinical Research Section of the of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) branch in Phoenix.

The populations being enrolled in the ETCHED study (for Early Tracking of Childhood Health Determinants) are at especially high risk of childhood obesity and metabolic dysfunction. Research conducted decades ago by the NIDDK in Phoenix showed that approximately 50% of Pima Indian children from diabetic pregnancies develop type 2 diabetes by age 25 (N Engl J Med. 1983;308:242-5). Years later, to tease out possible genetic factors, researchers compared siblings born before and after their mother was found to have type 2 diabetes, and found significantly higher rates of diabetes in those born after the mother’s diagnosis, affirming the role of in utero toxicity (Diabetes 2000;49:2208-11).

In the new study, the researchers will look at adipokines and inflammatory biomarkers in the mothers and offspring in addition to traditional anthropometric and glycemic measures. They’ll analyze placental tissue, breast milk, and the gut microbiome longitudinally, and they’ll lean heavily on genomics/epigenomics, proteomics, and metabolomics. “There’s potential,” Dr. Sinha said, “to develop a more accurate predictive and prognostic model of childhood obesity.”

The researchers also will study the role of family, socioeconomics, and environmental factors in influencing child growth patterns and they’ll look at neurodevelopment in infancy and childhood. As of October 2023, almost 80 pregnant women, most with obesity and almost one-third with type 2 diabetes, had enrolled in the study. Over the next several years, the study aims to enroll 750 dyads.
 

The Timing of In Utero Exposure

Shelley Ehrlich, MD, ScD, MPH, of the University of Cincinnati and Cincinnati Children’s Hospital Medical Center, is aiming, meanwhile, to learn how the timing of in utero exposure to hyperglycemia predicts specific metabolic and cardiovascular morbidities in the adult offspring of diabetic mothers.

“While we know that exposure to maternal diabetes, regardless of type, increases the risk of obesity, insulin resistance, diabetes, renal compromise, and cardiovascular disease in the offspring, there is little known about the level and timing of hyperglycemic exposure during fetal development that triggers these adverse outcomes,” said Dr. Ehrlich. A goal, she said, is to identify gestational profiles that predict phenotypes of offspring at risk for morbidity in later life.

She and other investigators with the TEAM (Transgenerational Effect on Adult Morbidity) study have recruited over 170 offspring of mothers who participated in the Diabetes in Pregnancy Program Project Grant (PPG) at the University of Cincinnati Medical Center from 1978 to 1995 — a landmark study that demonstrated the effect of strict glucose control in reducing major congenital malformations.

The women in the PPG study had frequent glucose monitoring (up to 6-8 times a day) throughout their pregnancies, and now, their recruited offspring, who are up to 43 years of age, are being assessed for obesity, diabetes/metabolic health, cardiovascular disease/cardiac and peripheral vascular structure and function, and other outcomes including those that may be amenable to secondary prevention (J Diabetes Res. Nov 1;2021:6590431).

Preliminary findings from over 170 offspring recruited between 2017 and 2022 suggest that in utero exposure to dysglycemia (as measured by standard deviations of glycohemoglobin) in the third trimester appears to increase the risk of morbid obesity in adulthood, while exposure to dysglycemia in the first trimester increases the risk of impaired glucose tolerance. The risk of B-cell dysfunction, meanwhile, appears to be linked to dysglycemia in the first and third trimesters — particularly the first — Dr. Ehrlich reported.

In 2019, we interviewed Andrea Prince, MD, who was completing her internship in the Inuit village of Puvirnituq, a town of 2000 inhabitants located in Nunavik, in the Canadian Far North. Five years later, still in her position, what perspective does she have on her practice? Have the challenges of practicing medicine in a remote region within the Inuit community affected her vocation? Would she recommend this experience to young doctors?

Question: What position do you currently hold?

Dr. Prince: I am a full-time general practitioner at Puvirnituq Hospital. My responsibilities range from following up on hospitalized patients to those seen in outpatient clinics for chronic illnesses. Within our medical team, I receive patients in the emergency department (day and night shifts), and I travel to smaller dispensaries nearby, especially to the village of Akulivik. So, it’s quite a varied practice.

More recently, I have been involved in remote continuing medical education projects in collaboration with specialists based in Montreal. In this context, we are increasingly trying to collaborate with doctors from other indigenous communities, such as the Grand Council of the Cree, because our practices are quite similar.



Q: What is the patient volume you see?

Dr. Prince: We see approximately 20-30 patients per day in the clinic, plus about 10 by appointment, and dozens of calls from dispensaries, in addition to patients transferred from other villages. There are four daytime doctors (one at night) and about 15 nurses stationed full-time at Puvirnituq Hospital.

Our practice relies heavily on collaboration with the nursing team, which has an expanded role — they can manage certain patients according to the treatment plan established by the doctor and prescribe treatments (eg, antibiotics for uncomplicated otitis).



Q: Access to care in these isolated regions is considered difficult. Have you observed any improvement in the situation over the past 5 years? What about new material and human resources?

Dr. Prince: For the past year, we have had a Starlink internet connection at the hospital, which facilitates telemedicine exchanges with specialists; we can now send data and medical images to Montreal to obtain expertise much more easily. Previously, everything was done by phone or with significant delays. We do not yet have a cellular network, and all records are currently in paper format.

But the challenges remain numerous. Progress is very slow. Like everywhere in the country, we are experiencing a shortage of staff, particularly an insufficient number of nurses. But the impact is even more dramatic in these isolated territories. We have had to close dispensaries on the coast due to a lack of personnel and only offer emergency services. However, patients have no other options; they cannot drive to another hospital. In Nunavik, the road network is practically nonexistent, and travel to other regions is by plane (about a 2.5-hour medical evacuation trip).

So, sometimes, patients do not seek care in time, and when we finally see them, unfortunately, the issue can be quite advanced.



Q: What are the most pressing logistical needs?

Dr. Prince: We still do not have a scanner in the Far North. This has a significant impact on mortality, especially in the case of accidents and trauma, which are very common in these regions. “Residents of Nunavik are four times more likely to suffer trauma than the rest of Quebec’s population and 40 times more likely to die from it,” as recently reported in La Presse.

There has also been much discussion about cancer mortality, with a risk for death about 70% higher following a lung cancer diagnosis (reported by Medscape Medical News). We do not have a mammogram machine to diagnose breast cancer. Before the COVID-19 pandemic, equipped diagnostic teams sometimes traveled to the region, but this is no longer the case. Today, a patient needing a mammogram will have to travel to Montreal. The same goes for colonoscopies, but visits are becoming less frequent. Therefore, campaigns to screen for certain common types of cancer are practically nonexistent.

As for urgent surgeries (appendicitis, cesarean sections, trauma, etc.), patients must be transferred to Montreal by medical evacuation. We have a visiting surgeon twice a year.



Q: What improvement strategies do you foresee despite the lack of resources?

Dr. Prince: The saying “prevention is better than cure” makes perfect sense in such remote regions under extreme conditions (it is impossible to fly a medevac when it is too windy or during a snowstorm!). That’s why my colleagues and I believe that prevention should be the top priority in terms of healthcare intervention. It may seem obvious, but nothing is simple in the Far North.



Q: In which areas should prevention campaigns be prioritized in your opinion?

Dr. Prince: An example is wearing helmets. Practically no one wears this type of protection in the Far North. They use all-terrain vehicles that are dangerous and for which helmet use is crucial. But they are simply not available in stores. So, communication is difficult: We tell people, “you need a helmet for the ATV, another for the bike, for the snowmobile, for playing hockey, etc.” when it is difficult to obtain one. With traumatologists in Montreal, we had a project to create multifunctional helmets for children — to protect them but also to develop a culture of helmet use, which is not common practice in the community — but these are projects that take a lot of time and are more complex than they seem.

Villages still do not have running water. Therefore, it is difficult to give recommendations to patients as they live in sanitary conditions that are unseen elsewhere in Canada. Without clean water, we cannot ensure that wound care is done properly. Not to mention the occurrence of hepatitis A epidemics, like the one we had to face.

Residents also grapple with significant alcohol and smoking problems, but there is no detox center or dedicated psychological help on site. To follow a detox program, patients would have to leave, move away from their families, and that can be psychologically very destabilizing. I try, in my practice, to talk to my patients about this, especially pregnant women — because many continue to smoke or drink during their pregnancy — but we need more resources.



Q: What about women’s health in this region?

Dr. Prince: We are fortunate to have a team of midwives, several of whom are Inuit, who are of great help in accessing contraception, performing cervical cancer screening tests, etc. But some patients with high-risk pregnancies who should be transferred to Montreal refuse to give birth away from their families. Again, if we had the means to allow high-risk women — or those for whom continuous monitoring or a cesarean section may be necessary — to give birth here safely, it would be a big step. As for abortion, it is feasible but remains a very taboo subject in the community.

Regarding violence against women, I have not observed any particularly encouraging developments in the past 5 years, but recently, we met with the mayor about this, hoping that concrete actions will be taken to help victims of violence.
 

Q: What is the predominant feeling in your daily life in a situation that is slow to evolve?

Dr. Prince: I remain hopeful for my patients. We must continue to fight! Initiatives must also come from the communities themselves; they must be involved in developing solutions. Because patients, too, need to have hope. They have the right to be cared for like other inhabitants of Canada.

On my part, I try to find a balance between feeling good about my caregiving profession and not burning out professionally. But burnout is a subject that concerns many doctors around the world and is increasingly being discussed. We should all have psychological support when entering medicine!



Q: Would you recommend colleagues to come and work in the Far North? What would you tell them?

Dr. Prince: I would tell them they will have no regrets! Yes, it’s difficult, but it’s a unique type of practice and very rewarding on a human level.

Professionally, it is a general practice that is no longer seen in the city today. The spectrum is very broad, ranging from neonatology to geriatrics, from the simplest to the most complex. It’s very stimulating. Diagnostically, practice is also very different from what is done in the metropolis. Without a scanner, you really have to question and investigate to evaluate whether a patient should be evacuated by plane to Montreal or not. It’s not trivial. Decisions must be made judiciously and quickly.

The human experience is also unique. Inuit communities are little known, and the aspects relayed in the media are often negative due to their increased risk for addiction. However, they are cheerful and very warm people, with an extraordinary culture. I have learned a lot from them, including reconsidering the notion of time, reviewing my priorities, and approaching life one day at a time.

I am very grateful to them for accepting me. I am sometimes even greeted with a “Welcome home!” when I return from vacation...Being told that in Nunavik, I am also “at home,” touches me immensely. I have seen children grow up, adolescents become adults. A bond of trust has developed.

Of course, all of this comes with sacrifices like being away from family and loved ones. We miss birthdays, weddings, etc. But without hesitation, it’s worth it!



Q: What are the next steps in your career in Nunavik? Will you stay for a long time?

Dr. Prince: I take it one day at a time, especially since I am about to take maternity leave very soon. But if a full-time return to Nunavik is difficult with a newborn, I know that the Nunavummiuts [inhabitants of Nunavik] will always be part of my life and my practice.

I want to remain involved with these communities, whether on-site (by practicing there a few months a year) or in Montreal where many patients are transferred. Coming to be treated in a big city (Montreal, 1.7M inhabitants), in very large hospitals, can be very stressful for them. They express themselves much less verbally than Westerners, so we must know how to listen to them, dedicate the necessary time to them, consider their culture and beliefs. I would like to be the familiar face they will encounter when they are cared for away from home. It’s a bond I want to preserve.

There are four daytime doctors (one at night) and about 15 nurses stationed full-time at Puvirnituq Hospital.

Our practice relies heavily on collaboration with the nursing team, which has an expanded role — they can manage certain patients according to the treatment plan established by the doctor and prescribe treatments (eg, antibiotics for uncomplicated otitis).



Q: Access to care in these isolated regions is considered difficult. Have you observed any improvement in the situation over the past 5 years? What about new material and human resources?

Dr. Prince: For the past year, we have had a Starlink internet connection at the hospital, which facilitates telemedicine exchanges with specialists; we can now send data and medical images to Montreal to obtain expertise much more easily. Previously, everything was done by phone or with significant delays. We do not yet have a cellular network, and all records are currently in paper format.

But the challenges remain numerous. Progress is very slow. Like everywhere in the country, we are experiencing a shortage of staff, particularly an insufficient number of nurses. But the impact is even more dramatic in these isolated territories. We have had to close dispensaries on the coast due to a lack of personnel and only offer emergency services. However, patients have no other options; they cannot drive to another hospital. In Nunavik, the road network is practically nonexistent, and travel to other regions is by plane (about a 2.5-hour medical evacuation trip).

So, sometimes, patients do not seek care in time, and when we finally see them, unfortunately, the issue can be quite advanced.



Q: What are the most pressing logistical needs?

Dr. Prince: We still do not have a scanner in the Far North. This has a significant impact on mortality, especially in the case of accidents and trauma, which are very common in these regions. “Residents of Nunavik are four times more likely to suffer trauma than the rest of Quebec’s population and 40 times more likely to die from it,” as recently reported in La Presse.

There has also been much discussion about cancer mortality, with a risk for death about 70% higher following a lung cancer diagnosis (reported by Medscape Medical News). We do not have a mammogram machine to diagnose breast cancer. Before the COVID-19 pandemic, equipped diagnostic teams sometimes traveled to the region, but this is no longer the case. Today, a patient needing a mammogram will have to travel to Montreal. The same goes for colonoscopies, but visits are becoming less frequent. Therefore, campaigns to screen for certain common types of cancer are practically nonexistent.

As for urgent surgeries (appendicitis, cesarean sections, trauma, etc.), patients must be transferred to Montreal by medical evacuation. We have a visiting surgeon twice a year.



Q: What improvement strategies do you foresee despite the lack of resources?

Dr. Prince: The saying “prevention is better than cure” makes perfect sense in such remote regions under extreme conditions (it is impossible to fly a medevac when it is too windy or during a snowstorm!). That’s why my colleagues and I believe that prevention should be the top priority in terms of healthcare intervention. It may seem obvious, but nothing is simple in the Far North.



Q: In which areas should prevention campaigns be prioritized in your opinion?

Dr. Prince: An example is wearing helmets. Practically no one wears this type of protection in the Far North. They use all-terrain vehicles that are dangerous and for which helmet use is crucial. But they are simply not available in stores. So, communication is difficult: We tell people, “you need a helmet for the ATV, another for the bike, for the snowmobile, for playing hockey, etc.” when it is difficult to obtain one. With traumatologists in Montreal, we had a project to create multifunctional helmets for children — to protect them but also to develop a culture of helmet use, which is not common practice in the community — but these are projects that take a lot of time and are more complex than they seem.

Villages still do not have running water. Therefore, it is difficult to give recommendations to patients as they live in sanitary conditions that are unseen elsewhere in Canada. Without clean water, we cannot ensure that wound care is done properly. Not to mention the occurrence of hepatitis A epidemics, like the one we had to face.

Residents also grapple with significant alcohol and smoking problems, but there is no detox center or dedicated psychological help on site. To follow a detox program, patients would have to leave, move away from their families, and that can be psychologically very destabilizing. I try, in my practice, to talk to my patients about this, especially pregnant women — because many continue to smoke or drink during their pregnancy — but we need more resources.



Q: What about women’s health in this region?

Dr. Prince: We are fortunate to have a team of midwives, several of whom are Inuit, who are of great help in accessing contraception, performing cervical cancer screening tests, etc. But some patients with high-risk pregnancies who should be transferred to Montreal refuse to give birth away from their families. Again, if we had the means to allow high-risk women — or those for whom continuous monitoring or a cesarean section may be necessary — to give birth here safely, it would be a big step. As for abortion, it is feasible but remains a very taboo subject in the community.

Regarding violence against women, I have not observed any particularly encouraging developments in the past 5 years, but recently, we met with the mayor about this, hoping that concrete actions will be taken to help victims of violence.
 

Q: What is the predominant feeling in your daily life in a situation that is slow to evolve?

Dr. Prince: I remain hopeful for my patients. We must continue to fight! Initiatives must also come from the communities themselves; they must be involved in developing solutions. Because patients, too, need to have hope. They have the right to be cared for like other inhabitants of Canada.

On my part, I try to find a balance between feeling good about my caregiving profession and not burning out professionally. But burnout is a subject that concerns many doctors around the world and is increasingly being discussed. We should all have psychological support when entering medicine!



Q: Would you recommend colleagues to come and work in the Far North? What would you tell them?

Dr. Prince: I would tell them they will have no regrets! Yes, it’s difficult, but it’s a unique type of practice and very rewarding on a human level.

Professionally, it is a general practice that is no longer seen in the city today. The spectrum is very broad, ranging from neonatology to geriatrics, from the simplest to the most complex. It’s very stimulating. Diagnostically, practice is also very different from what is done in the metropolis. Without a scanner, you really have to question and investigate to evaluate whether a patient should be evacuated by plane to Montreal or not. It’s not trivial. Decisions must be made judiciously and quickly.

The human experience is also unique. Inuit communities are little known, and the aspects relayed in the media are often negative due to their increased risk for addiction. However, they are cheerful and very warm people, with an extraordinary culture. I have learned a lot from them, including reconsidering the notion of time, reviewing my priorities, and approaching life one day at a time.

I am very grateful to them for accepting me. I am sometimes even greeted with a “Welcome home!” when I return from vacation...Being told that in Nunavik, I am also “at home,” touches me immensely. I have seen children grow up, adolescents become adults. A bond of trust has developed.

Of course, all of this comes with sacrifices like being away from family and loved ones. We miss birthdays, weddings, etc. But without hesitation, it’s worth it!



Q: What are the next steps in your career in Nunavik? Will you stay for a long time?

Dr. Prince: I take it one day at a time, especially since I am about to take maternity leave very soon. But if a full-time return to Nunavik is difficult with a newborn, I know that the Nunavummiuts [inhabitants of Nunavik] will always be part of my life and my practice.

I want to remain involved with these communities, whether on-site (by practicing there a few months a year) or in Montreal where many patients are transferred. Coming to be treated in a big city (Montreal, 1.7M inhabitants), in very large hospitals, can be very stressful for them. They express themselves much less verbally than Westerners, so we must know how to listen to them, dedicate the necessary time to them, consider their culture and beliefs. I would like to be the familiar face they will encounter when they are cared for away from home. It’s a bond I want to preserve.

TOPLINE:

New research shows increased screen time in children aged 12-36 months is associated with reduced verbal interactions between toddlers and their parents, which in turn could affect language development. 

METHODOLOGY:

• The study included data from 220 families in Australia.
• Researchers used advanced speech recognition technology to capture children’s screen time and language environment at home during a 16-hour window every 6 months.
• They adjusted for variables such as the sex of the child, the education level of the mother, and psychological distress in the primary caregiver.

TAKEAWAY: 

• Increases in screen time were associated with decreases in words spoken near children by adults, vocalizations by children, and back-and-forth interactions between adults and children. This correlation was especially notable at age 36 months.
• At age 36 months, each additional minute of screen time was linked to children hearing 6.6 fewer adult words, making 4.9 fewer vocalizations, and participating in 1.1 fewer conversational interactions.
• Based on the average daily screen time at that age seen in the study — 172 minutes (2.87 hours) — “children could be missing out on 1139 adult words, 843 vocalizations, and 194 conversational turns per day,” the researchers estimated.

IN PRACTICE:

“Identifying different ways that screen time could facilitate parent-child interactions, such as through interactive co-viewing, may be important strategies to support families given the current ubiquitous nature of screen time in families’ lives,” the authors of the study wrote.

What children watch and listen to may be an important consideration, according to a developmental scientist who was not involved with the study.

“It could be that less communicative contact with the caregiver is not as detrimental if the screen time is of high quality and developmentally appropriate, educational content,” Marina Bazhydai, PhD, with Lancaster University in Lancaster, United Kingdom, said in her comments on the research. 

SOURCE:

Mary E. Brushe, PhD, with Telethon Kids Institute and the University of Western Australia in Adelaide, was the corresponding author of the study. The research was published online in JAMA Pediatrics.

LIMITATIONS:

The study’s reliance on speech recognition technology did not capture all nuances of screen exposure.

DISCLOSURES:

There are over 3700 types of mosquitoes worldwide and over 200 types in the continental United States, of which only 12 are associated with transmitting diseases to humans. The majority are just a nuisance. Since they cannot readily be distinguished, strategies to prevent any bites are recommended.

West Nile Virus

In the US, West Nile virus (WNV) is the leading cause of neuroinvasive arboviral disease. Just hearing the name took me back to New York in 1999 when sightings of dead birds around the city and boroughs were reported daily. The virus was isolated that same year. The enzootic circle occurs between mosquitoes and birds, which are the primary vertebrate host via the bite of Culex mosquitoes. After a bite from an infected mosquito, humans are usually a dead-end host since the level and duration of viremia needed to infect another mosquito is insufficient.

Human-to-human transmission is documented through blood transfusion and solid organ transplantation. Vertical transmission is rarely described. Initially isolated in New York, WNV quickly spread across North America and has been isolated in every continent except Antarctica. Most cases occur in the summer and autumn.

Most infected individuals are asymptomatic. Those who do develop symptoms have fever, headache, myalgia, arthralgia, nausea, vomiting, and a transient rash. Less than 1% develop meningitis/encephalitis symptoms similar to other causes of aseptic meningitis. Those with encephalitis in addition to fever and headache may have altered mental status and focal neurologic deficits including flaccid paralysis or movement disorders.

Detection of anti-WNV IgM antibodies (AB) in serum or CSF is the most common way to make the diagnosis. IgM AB usually is present within 3-8 days after onset of symptoms and persists up to 90 days. Data from ArboNET, the national arboviral surveillance system managed by Centers for Disease Control and Prevention and state health departments, reveal that from 1999 to 2022 there were 56,575 cases of WNV including 28,684 cases of neuroinvasive disease. In 2023 there were 2,406 and 1,599 cases, respectively. Those historic totals for WNV are 10 times greater than the totals for all the other etiologies of neuroinvasive arboviral diseases in the US combined (Jamestown Canyon, LaCrosse, St. Louis, and Eastern Equine encephalitis n = 1813).

Remember to include WNV in your differential of a febrile patient with neurologic symptoms, mosquito bites, blood transfusions, and organ transplantation. Treatment is supportive care.

The US began screening all blood donations for WNV in 2003. Organ donor screening is not universal.

Dengue

Dengue, another arbovirus, is transmitted by bites of infected Aedes aegypti and Aedes albopictus mosquitoes, which prefer to feed during the daytime. There are four dengue virus serotypes: DENV-1 DENV-2, DENV-3 and DENV-4. In endemic areas, all four serotypes are usually co-circulating and people can be infected by each one.

Long-term immunity is type specific. Heterologous protection lasts only a few months. Dengue is endemic throughout the tropics and subtropics of Asia, Africa, and the Americas. Approximately 53% of the world’s population live in an area where dengue transmission can occur. In the US, most cases are reported from Puerto Rico. Dengue is endemic in the following US territories: Puerto Rico, US Virgin Islands, American Samoa, and free associated states. Most cases reported on the mainland are travel related. However, locally acquired dengue has been reported. From 2010 to 2023 Hawaii reported 250 cases, Florida 438, and Texas 40 locally acquired cases. During that same period, Puerto Rico reported more than 32,000 cases. It is the leading cause of febrile illness for travelers returning from the Caribbean, Latin America, and South Asia.Peru is currently experiencing an outbreak with more than 25,000 cases reported since January 2024. Most cases of dengue occur in adolescents and young adults. Severe disease occurs most often in infants, those with underlying chronic disease, pregnant women, and persons infected with dengue for the second time.

Symptoms range from a mild febrile illness to severe disease associated with hemorrhage and shock. Onset is usually 7-10 days after infection and symptoms include high fever, severe headache, retro-orbital pain, arthralgia and myalgias, nausea, and vomiting; some may develop a generalized rash.

The World Health Organization (WHO) classifies dengue as 1) dengue with or without warning signs for progression of disease and 2) severe dengue. Warning signs for disease progression include abdominal pain or tenderness, persistent vomiting, fluid accumulation (e.g., ascites, pericardial or pleural effusion), mucosal bleeding, restlessness, postural hypotension, liver enlargement greater than 2 cm. Severe dengue is defined as any sign of severe plasma leakage leading to shock, severe bleeding or organ failure, or fluid accumulation with respiratory distress. Management is supportive care.

Prevention: In the US, Dengvaxia, a live attenuated tetravalent vaccine, is approved for use in children aged 9–16 years with laboratory-confirmed previous dengue virus infection and living in areas where dengue is endemic. It is administered at 0, 6, and 12 months. It is not available for purchase on the mainland. Continued control of the vector and personal protection is necessary to prevent recurrent infections.
 

CHIKV

Chikungunya (CHIKV), which means “that which bends up” in the Mkonde language of Tanzania, refers to the appearance of the person with severe usually symmetric arthralgias characteristic for this infection that otherwise is often clinically confused with dengue and Zika. It too is transmitted by A. aegypti and A. albopictus and is prevalent in tropical Africa, Asia, Central and South America, and the Caribbean. Like dengue it is predominantly an urban disease. The WHO reported the first case in the Western Hemisphere in Saint Martin in December 2013. By August 2014, 31 additional territories and Caribbean or South American countries reported 576,535 suspected cases.Florida first reported locally acquired CHIKV in June 2014. By December an additional 11 cases had been identified. Texas reported one case in 2015. Diagnosis is with IgM ab or PCR. Treatment is supportive with most recovering from acute illness within 2 weeks. Data in adults indicate 40-52% may develop chronic or recurrent joint pain.

Prevention: IXCHIQ, a live attenuated vaccine, was licensed in November 2023 and recommended by the CDC in February 2024 for use in persons at least 18 years of age with travel to destinations where there is a CHIKV outbreak. It may be considered for persons traveling to a country or territory without an outbreak but with evidence of CHIKV transmission among humans within the last 5 years and those staying in endemic areas for a cumulative period of at least 6 months over a 2-year period. Specific recommendations for lab workers and persons older than 65 years were also made. This is good news for your older patients who may be participating in mission trips, volunteering, studying abroad, or just vacationing in an endemic area. Adolescent vaccine trials are ongoing and pediatric trials will soon be initiated. In addition, vector control and use of personal protective measures cannot be emphasized enough.

There are several other mosquito borne diseases, however our discussion here is limited to three. Why these three? WNV as a reminder that it is the most common neuroinvasive agent in the US. Dengue and CHIKV because they are not endemic in the US so they might not routinely be considered in febrile patients; both diseases have been reported and acquired on the mainland and your patients may travel to an endemic area and return home with an unwanted souvenir. You will be ready for them.

Just hearing the name took me back to New York in 1999 when sightings of dead birds around the city and boroughs were reported daily. The virus was isolated that same year. The enzootic circle occurs between mosquitoes and birds, which are the primary vertebrate host via the bite of Culex mosquitoes. After a bite from an infected mosquito, humans are usually a dead-end host since the level and duration of viremia needed to infect another mosquito is insufficient.

Human-to-human transmission is documented through blood transfusion and solid organ transplantation. Vertical transmission is rarely described. Initially isolated in New York, WNV quickly spread across North America and has been isolated in every continent except Antarctica. Most cases occur in the summer and autumn.

Most infected individuals are asymptomatic. Those who do develop symptoms have fever, headache, myalgia, arthralgia, nausea, vomiting, and a transient rash. Less than 1% develop meningitis/encephalitis symptoms similar to other causes of aseptic meningitis. Those with encephalitis in addition to fever and headache may have altered mental status and focal neurologic deficits including flaccid paralysis or movement disorders.

Detection of anti-WNV IgM antibodies (AB) in serum or CSF is the most common way to make the diagnosis. IgM AB usually is present within 3-8 days after onset of symptoms and persists up to 90 days. Data from ArboNET, the national arboviral surveillance system managed by Centers for Disease Control and Prevention and state health departments, reveal that from 1999 to 2022 there were 56,575 cases of WNV including 28,684 cases of neuroinvasive disease. In 2023 there were 2,406 and 1,599 cases, respectively. Those historic totals for WNV are 10 times greater than the totals for all the other etiologies of neuroinvasive arboviral diseases in the US combined (Jamestown Canyon, LaCrosse, St. Louis, and Eastern Equine encephalitis n = 1813).

Remember to include WNV in your differential of a febrile patient with neurologic symptoms, mosquito bites, blood transfusions, and organ transplantation. Treatment is supportive care.

The US began screening all blood donations for WNV in 2003. Organ donor screening is not universal.

Dengue

Dengue, another arbovirus, is transmitted by bites of infected Aedes aegypti and Aedes albopictus mosquitoes, which prefer to feed during the daytime. There are four dengue virus serotypes: DENV-1 DENV-2, DENV-3 and DENV-4. In endemic areas, all four serotypes are usually co-circulating and people can be infected by each one.

Long-term immunity is type specific. Heterologous protection lasts only a few months. Dengue is endemic throughout the tropics and subtropics of Asia, Africa, and the Americas. Approximately 53% of the world’s population live in an area where dengue transmission can occur. In the US, most cases are reported from Puerto Rico. Dengue is endemic in the following US territories: Puerto Rico, US Virgin Islands, American Samoa, and free associated states. Most cases reported on the mainland are travel related. However, locally acquired dengue has been reported. From 2010 to 2023 Hawaii reported 250 cases, Florida 438, and Texas 40 locally acquired cases. During that same period, Puerto Rico reported more than 32,000 cases. It is the leading cause of febrile illness for travelers returning from the Caribbean, Latin America, and South Asia.Peru is currently experiencing an outbreak with more than 25,000 cases reported since January 2024. Most cases of dengue occur in adolescents and young adults. Severe disease occurs most often in infants, those with underlying chronic disease, pregnant women, and persons infected with dengue for the second time.

Symptoms range from a mild febrile illness to severe disease associated with hemorrhage and shock. Onset is usually 7-10 days after infection and symptoms include high fever, severe headache, retro-orbital pain, arthralgia and myalgias, nausea, and vomiting; some may develop a generalized rash.

The World Health Organization (WHO) classifies dengue as 1) dengue with or without warning signs for progression of disease and 2) severe dengue. Warning signs for disease progression include abdominal pain or tenderness, persistent vomiting, fluid accumulation (e.g., ascites, pericardial or pleural effusion), mucosal bleeding, restlessness, postural hypotension, liver enlargement greater than 2 cm. Severe dengue is defined as any sign of severe plasma leakage leading to shock, severe bleeding or organ failure, or fluid accumulation with respiratory distress. Management is supportive care.

Prevention: In the US, Dengvaxia, a live attenuated tetravalent vaccine, is approved for use in children aged 9–16 years with laboratory-confirmed previous dengue virus infection and living in areas where dengue is endemic. It is administered at 0, 6, and 12 months. It is not available for purchase on the mainland. Continued control of the vector and personal protection is necessary to prevent recurrent infections.
 

CHIKV

Chikungunya (CHIKV), which means “that which bends up” in the Mkonde language of Tanzania, refers to the appearance of the person with severe usually symmetric arthralgias characteristic for this infection that otherwise is often clinically confused with dengue and Zika. It too is transmitted by A. aegypti and A. albopictus and is prevalent in tropical Africa, Asia, Central and South America, and the Caribbean. Like dengue it is predominantly an urban disease. The WHO reported the first case in the Western Hemisphere in Saint Martin in December 2013. By August 2014, 31 additional territories and Caribbean or South American countries reported 576,535 suspected cases.Florida first reported locally acquired CHIKV in June 2014. By December an additional 11 cases had been identified. Texas reported one case in 2015. Diagnosis is with IgM ab or PCR. Treatment is supportive with most recovering from acute illness within 2 weeks. Data in adults indicate 40-52% may develop chronic or recurrent joint pain.

Prevention: IXCHIQ, a live attenuated vaccine, was licensed in November 2023 and recommended by the CDC in February 2024 for use in persons at least 18 years of age with travel to destinations where there is a CHIKV outbreak. It may be considered for persons traveling to a country or territory without an outbreak but with evidence of CHIKV transmission among humans within the last 5 years and those staying in endemic areas for a cumulative period of at least 6 months over a 2-year period. Specific recommendations for lab workers and persons older than 65 years were also made. This is good news for your older patients who may be participating in mission trips, volunteering, studying abroad, or just vacationing in an endemic area. Adolescent vaccine trials are ongoing and pediatric trials will soon be initiated. In addition, vector control and use of personal protective measures cannot be emphasized enough.

There are several other mosquito borne diseases, however our discussion here is limited to three. Why these three? WNV as a reminder that it is the most common neuroinvasive agent in the US. Dengue and CHIKV because they are not endemic in the US so they might not routinely be considered in febrile patients; both diseases have been reported and acquired on the mainland and your patients may travel to an endemic area and return home with an unwanted souvenir. You will be ready for them.

With rates of syphilis rising quickly in the United States and elsewhere, clinicians are having to up their game when it comes to diagnosing and treating an infection that they may not be paying enough attention to.

More than 200,000 cases of syphilis were reported in the United States in 2022, which is the highest number since 1950 and is a 17.3% increase over 2021, according to the latest figures from the Centers for Disease Control and Prevention (CDC). The rate of infection has increased almost every year since a historic low in 2001.

And the trend is not limited to the United States. Last year, the infection rate in the United Kingdom hit a 50-year high, said David Mabey, BCh, DM, from the London School of Hygiene and Tropical Medicine. Syphilis and other sexually transmitted infections are also a major problem in low- and middle-income countries, he added, although good data are not always available.

Many of today’s healthcare professionals have little experience with the disease, shared Ina Park, MD, a sexually transmitted infections specialist at the University of California at San Francisco. “An entire generation of physicians — including myself — did not see any cases until we were well out of our training,” Dr. Park reported. “We’re really playing catch-up.”
 

A Centuries-Old Ailment

Dr. Park offered some advice on the challenges of diagnosing what can be an elusive infection at the Conference on Retroviruses and Opportunistic Infections (CROI) 2024 Annual Meeting in Denver. That advice boiled down to one simple rule: “Test, test, test.”

Because syphilis can mimic so many other conditions and can have long periods of latency, it can be easily missed or even misdiagnosed by experienced physicians, said Dr. Park. Clinicians need to keep it front of mind and have a lower threshold for testing, even if there are no obvious symptoms.

Following the CDC’s new recommendations for syphilis screening will help, she noted; every sexually active patient aged between 15 and 44 years who lives in a county with a syphilis infection rate of 4.6 per 100,000 people or higher should get the test. And clinicians should remain vigilant, even in areas with a lower prevalence. “If you can’t account for new symptoms in a sexually active patient, order a test,” said Dr. Park.
 

Complicated Cases

The lack of experience with syphilis affects not just diagnosis but also treatment, particularly for complex cases, said Khalil Ghanem, MD, PhD, from the Johns Hopkins University School of Medicine in Baltimore. “When you don’t have to deal with something for a while, you forget how to deal with it,” he added.

At CROI, Dr. Ghanem offered suggestions for how to navigate complicated cases of ocular syphilis, otic syphilis, and neurosyphilis, and how to interpret test results when a patient’s antigen titers are being “unruly.”

With potential ocular or otic syphilis, you shouldn’t wait for a specialist like an ophthalmologist to weigh in but instead refer the patient directly to the emergency department because of the risk that the symptoms may become irreversible and result in permanent blindness or deafness. “You don’t want to dilly-dally with those conditions,” Dr. Ghanem said.

Closely monitoring a patient’s rapid plasma regain and venereal disease research laboratory antigen levels is the only way to manage syphilis and to determine whether the infection is responding to treatment, he noted, but sometimes those titers “don’t do what you think they should be doing” and fail to decline or even go up after treatment.

“You don’t know if they went up because the patient was re-infected, or they developed neurosyphilis, or there was a problem at the lab,” he said. “It can be challenging to interpret.”

To decipher confusing test results, Dr. Ghanem recommended getting a detailed history to understand whether a patient is at risk for reinfection, whether there are signs of neurosyphilis or other complications, whether pregnancy is possible, and so on. “Based on the answers, you can determine what the most rational approach to treatment would be,” he shared.
 

Drug Shortages

Efforts to get the infection under control have become more complicated. Last summer, Pfizer announced that it had run out of penicillin G benzathine (Bicillin), an injectable, long-acting drug that is one of the main treatments for syphilis and the only one that can be given to pregnant people. Supplies for children ran out at the end of June 2023, and supplies for adults were gone by the end of September.

Because Pfizer is the only company that manufactures penicillin G benzathine, there is no one to pick up the slack in the short-term, so the shortage is expected to continue until at least the middle of 2024.

In response, the US Food and Drug Administration has temporarily allowed the use of benzylpenicillin benzathine (Extencilline), a French formulation that has not been approved in the United States, until supplies of penicillin G benzathine are stabilized.

The shortage has shone a spotlight on the important issue of a lack of alternatives for the treatment of syphilis during pregnancy, which increases the risk for congenital syphilis. “Hopefully, this pushes the National Institutes of Health and others to step up their game on studies for alternative drugs for use in pregnancy,” Dr. Ghanem said.

The new RSV antibody treatment for babies has been highly effective in its first season, according to a first look at data from four children’s hospitals.

Babies who received the new preventive treatment for RSV shortly after birth were 90% less likely to be severely sickened with the potentially deadly respiratory illness, according to the new estimate published by the Centers for Disease Control and Prevention. It is the first real-world evaluation of Beyfortus (the generic name is nirsevimab), which was approved by the Food and Drug Administration last July.

RSV is a seasonal illness that affects more people — particularly infants and the elderly — in the fall and winter. Symptoms are usually mild in healthy adults, but infants are particularly at risk of getting bronchiolitis, which results in exhausting wheezing and coughing in babies due to swelling in their airways and lungs. Babies who are hospitalized may need fluids and medical devices to help them breathe.

RSV peaked this season from November to January, with more than 10,000 monthly diagnoses reported to the CDC. 

The new CDC analysis was conducted among about 700 babies hospitalized for severe respiratory problems from October to the end of February. Among the babies in the study, 407 were diagnosed with RSV and 292 tested negative. The researchers found that 1% of babies in the study who were diagnosed with RSV had received Beyfortus, while the remaining babies who were positive for the virus had not. 

Among the babies hospitalized for other severe respiratory problems, 18% had received Beyfortus. Overall, just 59 babies among the nearly 700 in the study received Beyfortus, perhaps reflecting the short supply of the medicine the first season it was available. The report authors noted that babies in the study who did receive Beyfortus also tended to have high-risk medical conditions.

The number of babies nationwide who received Beyfortus during this first season of availability is unclear, but a January CDC survey showed that 4 in 10 parents said their babies under 8 months old had received the treatment. The Wall Street Journal reported recently that a shortage last fall resulted from underestimated demand and from production plans that were set before the CDC decided to recommend that all infants under 8 months old receive Beyfortus if their mothers did not get a maternal vaccine that can protect infants from RSV.

Both the antibody treatment for infants and the maternal vaccine were shown in clinical trials to be about 80% effective at preventing severe illness stemming from RSV.

The authors of the latest CDC report concluded that “this early estimate supports the current nirsevimab recommendation for the prevention of severe RSV disease in infants. Infants should be protected by maternal RSV vaccination or infant receipt of nirsevimab.”

Bullying, heavy social media use, experimentation with drugs and alcohol: These are the well-described hazards of adolescence. We have growing knowledge of the risks associated with these experiences and which youth are more vulnerable to these risks. Developmentally, adolescence is a time of critical brain development marked by heightened sensitivity to social approval and limited impulse control. Adolescents also have growing autonomy from parents alongside a stronger need for time with friends (the new peer home away from the parental home). These factors alone make adolescence a period of heightened sensitivity to these experiences, but some youth have greater vulnerability to develop psychopathology such as anxiety, depression, eating disorders, or addiction after exposure to these common experiences. Pediatricians can assess these broader vulnerabilities during well child visits of pre- and early teens and offer patients and their parents strategies for minimizing risk and cultivating resilience.

Bullying

Bullying, both verbal and physical, has long been an unwelcome part of youth. Cellphones and social media have brought bullying into the 21st century. Cyberbullying has meant that targeted youth are no longer safe after school and it carries higher risk of self-harm and suicidality than the analog version. No child benefits from bullying, but some children are more vulnerable to develop an anxiety or mood disorder, self-injury, or suicidality, whereas others experience stress and distress, but are able to adaptively seek support from friends and adults and stay on track developmentally, even to flourish. There is evidence that girls and LGBTQ youth are more commonly bullied and at higher risk for depression, self-harm, and suicidality as a consequence of cyberbullying. Youth already suffering from a psychiatric illness or substance abuse who are bullied are at higher risk for self-harm and suicidality than that of their bullied peers. Youth whose parents score high on measures of distress and family dysfunction also face higher risk of self-harm and suicidality after bullying.¹

Social Media

Unlike bullying, social media has been a force only in 21st century life, with Facebook starting in 2004 and cellphones in common use by adolescents in the past 2 decades. While there are potential benefits of social media use, such as stronger connections to supportive peers for isolated LGBTQ youth or youth who live in rural areas, there are also risks. Of course, social media carries the risk of cyberbullying. It also carries the risk for very heavy patterns of use that can interfere with physical activity, adequate sleep, academic performance, and healthy in-person social activities. There is robust emerging evidence that heavy users have higher rates of mood disorders and anxiety symptoms, although it is unclear whether social media exacerbates, or more social media use is the result of depression and/or anxiety. Adolescents’ desire for social acceptance makes them especially sensitive to the social rewards of “likes” and they are thus vulnerable to becoming heavy users. Adolescent girls who are heavy users are vulnerable to developing a disordered body image and eating disorders. Those youth with especially low levels of impulse control, such as those with ADHD, have greater risk of developing problematic use.^2-4

Substance Use and Abuse

Exploration of alcohol and drug use has been a common experience, and hazard, of adolescence for many generations. As a result, we have richer knowledge of those factors that are associated with risk of and protection against that use progressing to a use disorder. Earlier age at first experimentation appears to be independently correlated with increased risk of developing a substance use disorder. Every pediatrician should be aware of a family history of substance use disorders, especially alcohol, as they are strongly associated with higher risk. Youth with temperaments that are sensation seeking, externalizing and impulsive are at higher risk. Youth with anxiety and mood disorders and untreated attention deficit disorders are at higher risk. Youth whose parents have high levels of conflict or “permissive” parenting styles are at higher risk as are those who as children experienced abuse or neglect.^5-7

Minimizing Risk and Cultivating Resilience

Protective factors balance these risks: adequate sleep; positive relationships with friends and parents; and confidence in their academic, athletic, or social abilities all are correlated with good outcomes after bullying, drug and alcohol use, and social media use. These teenagers are meaningfully connected to caring adults and peers, have a future orientation, and typically have higher self-esteem. Youth whose parents balance attunement with rules and expectations (“authoritative” parenting) appear to be at lower risk of poor mental health outcomes associated with heavy social media use as well as other risk behaviors. These parents have clear rules and expectations, including about drugs and alcohol, and enforce rules reasonably calmly and consistently. Youth whose families eat dinner together at least three times weekly, who attend schools that offer a wide range of after-school activities, and who learn to use problem-focused coping skills rather than emotion-focused coping skills are protected against poor mental health outcomes in the face of these challenges.

While bullying is a stressor, social media and substances may seem like ways of managing stress and connecting with peers. There are youth with clear vulnerabilities to the risks associated with each of them. Shared factors include vulnerable temperaments, high conflict or permissive parenting, family history of substance use disorders or preexisting psychiatric illness. Pediatricians are in a unique position to raise teenagers’ awareness of their specific vulnerabilities. Talk about the heightened risk of experimentation with alcohol or drugs in your patients who are in treatment for an anxiety or mood disorder. Help them cultivate critical thinking — an adolescent specialty — around marketing and peer pressure. Remind them that social media companies make money from keeping them online longer. Then help them identify what strategies are in their control, such as limiting their time online. What else could they be doing with their time that they actually enjoy? Remind them about the value of protecting time for adequate sleep, regular exercise, and sitting down for dinner with their family. Ask about their nourishing relationships with peers and adults and talk about the value of protecting time for them. Ask your patients and their parents about how they face stress, emphasizing their ability to locate what is within their control. While awareness of feelings is important, learning to manage intense emotions is more connected to healthy habits of sleep and exercise and strategies to get support or pivot to engaging activities. Discussing this openly models for parents how to bear difficulty alongside their children without becoming distressed or punitive themselves. Talk with worried parents about the value of regular meals together, shared physical activities, and supporting time for their children’s emerging interests and hobbies. Equipping your patients and their parents with knowledge about their particular vulnerabilities, reminders about what is known about these risks, and all that is in their power to build resilience, may be as meaningful a public health intervention as asking them about biking with helmets and using seat belts.

Bullying, heavy social media use, experimentation with drugs and alcohol: These are the well-described hazards of adolescence. We have growing knowledge of the risks associated with these experiences and which youth are more vulnerable to these risks. Developmentally, adolescence is a time of critical brain development marked by heightened sensitivity to social approval and limited impulse control. Adolescents also have growing autonomy from parents alongside a stronger need for time with friends (the new peer home away from the parental home). These factors alone make adolescence a period of heightened sensitivity to these experiences, but some youth have greater vulnerability to develop psychopathology such as anxiety, depression, eating disorders, or addiction after exposure to these common experiences. Pediatricians can assess these broader vulnerabilities during well child visits of pre- and early teens and offer patients and their parents strategies for minimizing risk and cultivating resilience.

Bullying

Bullying, both verbal and physical, has long been an unwelcome part of youth. Cellphones and social media have brought bullying into the 21st century. Cyberbullying has meant that targeted youth are no longer safe after school and it carries higher risk of self-harm and suicidality than the analog version. No child benefits from bullying, but some children are more vulnerable to develop an anxiety or mood disorder, self-injury, or suicidality, whereas others experience stress and distress, but are able to adaptively seek support from friends and adults and stay on track developmentally, even to flourish. There is evidence that girls and LGBTQ youth are more commonly bullied and at higher risk for depression, self-harm, and suicidality as a consequence of cyberbullying. Youth already suffering from a psychiatric illness or substance abuse who are bullied are at higher risk for self-harm and suicidality than that of their bullied peers. Youth whose parents score high on measures of distress and family dysfunction also face higher risk of self-harm and suicidality after bullying.¹

Social Media

Unlike bullying, social media has been a force only in 21st century life, with Facebook starting in 2004 and cellphones in common use by adolescents in the past 2 decades. While there are potential benefits of social media use, such as stronger connections to supportive peers for isolated LGBTQ youth or youth who live in rural areas, there are also risks. Of course, social media carries the risk of cyberbullying. It also carries the risk for very heavy patterns of use that can interfere with physical activity, adequate sleep, academic performance, and healthy in-person social activities. There is robust emerging evidence that heavy users have higher rates of mood disorders and anxiety symptoms, although it is unclear whether social media exacerbates, or more social media use is the result of depression and/or anxiety.

A phase 3 trial of a maternal vaccine candidate for respiratory syncytial virus (RSV) has been stopped early because the risk for preterm births is higher in the candidate vaccine group than in the placebo group.

By the time enrollment was stopped on February 25, 2022 because of the safety signal of preterm birth, 5328 pregnant women had been vaccinated, about half of the intended 10,000 enrollees. Of these, 3557 received the candidate vaccine RSV prefusion F protein–based maternal vaccine, and another 1771 received a placebo.

Data from the trial, sponsored by GSK, were immediately made available when recruitment and vaccination were stopped, and investigation of the preterm birth risk followed. Results of that analysis, led by Ilse Dieussaert, IR, vice president for vaccine development at GSK in Wavre, Belgium, are published online on March 13 in The New England Journal of Medicine. 

“We have discontinued our work on this RSV maternal candidate vaccine, and we are closing out all ongoing trials with the exception of the MAT-015 follow-on study to monitor subsequent pregnancies,” a GSK spokesperson said in an interview.

The trial was conducted in pregnant women aged 18-49 years to assess the efficacy and safety of the vaccine. The women were randomly assigned 2:1 to receive the candidate vaccine or placebo between 24 and 34 weeks’ gestation.
 

Preterm Births

The primary outcomes were any or severe medically assessed RSV-associated lower respiratory tract infection in infants from birth to 6 months and safety in infants from birth to 12 months.

According to the data, preterm birth occurred in 6.8% of the infants in the vaccine group and in 4.9% of those in the placebo group (relative risk [RR], 1.37; 95% CI, 1.08-1.74; P = .01). Neonatal death occurred in 0.4% in the vaccine group and 0.2% in the placebo group (RR, 2.16; 95% CI, 0.62-7.56; P = .23).

To date, only one RSV vaccine (Abrysvo, Pfizer) has been approved for use during pregnancy to protect infants from RSV-associated lower respiratory tract infection.

“It was a very big deal that this trial was stopped, and the new candidate won’t get approval.” said Aaron E. Glatt, MD, chair of the Department of Medicine and chief of Infectious Diseases and Hospital Epidemiologist at Mount Sinai South Nassau in Oceanside, New York.
 

Only One RSV Vaccine Approved in Pregnancy

Dr. Glatt pointed out the GSK vaccine is like the maternal vaccine that did get approved. “The data clearly show that there was a slight but increased risk in preterm labor,” Dr. Glatt said, “and while not as clearly shown, there was an increase in neonatal death in the group of very small numbers, but any neonatal death is of concern.”

The implications were disturbing, he added, “You’re giving this vaccine to prevent neonatal death.” Though the Pfizer vaccine that was granted approval had a very slight increase in premature birth, the risk wasn’t statistically significant, he pointed out, “and it showed similar benefits in preventing neonatal illness, which can be fatal.”

Dr. Glatt said that there is still a lingering concern with the approved vaccine, and he explained that most clinicians will give it closer to the end of the recommended time window of 34 weeks. “This way, even if there is a slight increase in premature term labor, you’re probably not going to have a serious outcome because the baby will be far enough along.”

A difference in the incidence of preterm birth between the experimental vaccine and placebo groups was predominantly found in low- and middle-income countries, according to Dieussaert’s team, “where approximately 50% of the trial population was enrolled and where the medical need for maternal RSV vaccines is the greatest.”

The RR was 1.56 (95% CI, 1.17-2.10) for low- and middle-income countries and 1.04 (95% CI, 0.68-1.58) for high-income countries. 

“If a smaller percentage of participants from low- and middle-income countries had been enrolled in our trial, the RR for preterm birth in the vaccine group as compared with the placebo group might have been reduced in the overall trial population,” they reported.

The authors explained that the data do not reveal the cause of the higher risk for preterm birth in the vaccine group.

“We do not know what caused the signal,” the company’s spokesperson added. “GSK completed all the necessary steps of product development including preclinical toxicology studies and clinical studies in nonpregnant women prior to starting the studies in pregnant women. There were no safety signals identified in any of the earlier parts of the clinical testing. There have been no safety signals identified in the other phase 3 trials for this vaccine candidate.”

Researchers did not find a correlation between preterm births in the treatment vs control groups with gestational age at the time of vaccination or with particular vaccine clinical trial material lots, race, ethnicity, maternal smoking, alcohol consumption, body mass index, or time between study vaccination and delivery, the GSK spokesperson said.

The spokesperson noted that the halted vaccine is different from GSK’s currently approved adjuvanted RSV vaccine (Arexvy) for adults aged 60 years or older.

What’s Next for Other Vaccines

Maternal vaccines have been effective in preventing other diseases in infants, such as tetanus, influenza, and pertussis, but RSV is a very hard virus to make a vaccine for, Dr. Glatt shared.

The need is great to have more than one option for a maternal RSV vaccine, he added, to address any potential supply concerns.

“People have to realize how serious RSV can be in infants,” he said. “It can be a fatal disease. This can be a serious illness even in healthy children.”

Researchers did not find a correlation between preterm births in the treatment vs control groups with gestational age at the time of vaccination or with particular vaccine clinical trial material lots, race, ethnicity, maternal smoking, alcohol consumption, body mass index, or time between study vaccination and delivery, the GSK spokesperson said.

The spokesperson noted that the halted vaccine is different from GSK’s currently approved adjuvanted RSV vaccine (Arexvy) for adults aged 60 years or older.

What’s Next for Other Vaccines

Maternal vaccines have been effective in preventing other diseases in infants, such as tetanus, influenza, and pertussis, but RSV is a very hard virus to make a vaccine for, Dr. Glatt shared.

The need is great to have more than one option for a maternal RSV vaccine, he added, to address any potential supply concerns.

“People have to realize how serious RSV can be in infants,” he said. “It can be a fatal disease. This can be a serious illness even in healthy children.”

A phase 3 trial of a maternal vaccine candidate for respiratory syncytial virus (RSV) has been stopped early because the risk for preterm births is higher in the candidate vaccine group than in the placebo group.

By the time enrollment was stopped on February 25, 2022 because of the safety signal of preterm birth, 5328 pregnant women had been vaccinated, about half of the intended 10,000 enrollees. Of these, 3557 received the candidate vaccine RSV prefusion F protein–based maternal vaccine, and another 1771 received a placebo.

Data from the trial, sponsored by GSK, were immediately made available when recruitment and vaccination were stopped, and investigation of the preterm birth risk followed. Results of that analysis, led by Ilse Dieussaert, IR, vice president for vaccine development at GSK in Wavre, Belgium, are published online on March 13 in The New England Journal of Medicine. 

“We have discontinued our work on this RSV maternal candidate vaccine, and we are closing out all ongoing trials with the exception of the MAT-015 follow-on study to monitor subsequent pregnancies,” a GSK spokesperson said in an interview.

The trial was conducted in pregnant women aged 18-49 years to assess the efficacy and safety of the vaccine. The women were randomly assigned 2:1 to receive the candidate vaccine or placebo between 24 and 34 weeks’ gestation.
 

Preterm Births

The primary outcomes were any or severe medically assessed RSV-associated lower respiratory tract infection in infants from birth to 6 months and safety in infants from birth to 12 months.

According to the data, preterm birth occurred in 6.8% of the infants in the vaccine group and in 4.9% of those in the placebo group (relative risk [RR], 1.37; 95% CI, 1.08-1.74; P = .01). Neonatal death occurred in 0.4% in the vaccine group and 0.2% in the placebo group (RR, 2.16; 95% CI, 0.62-7.56; P = .23).

To date, only one RSV vaccine (Abrysvo, Pfizer) has been approved for use during pregnancy to protect infants from RSV-associated lower respiratory tract infection.

“It was a very big deal that this trial was stopped, and the new candidate won’t get approval.” said Aaron E. Glatt, MD, chair of the Department of Medicine and chief of Infectious Diseases and Hospital Epidemiologist at Mount Sinai South Nassau in Oceanside, New York.
 

Only One RSV Vaccine Approved in Pregnancy

Dr. Glatt pointed out the GSK vaccine is like the maternal vaccine that did get approved. “The data clearly show that there was a slight but increased risk in preterm labor,” Dr. Glatt said, “and while not as clearly shown, there was an increase in neonatal death in the group of very small numbers, but any neonatal death is of concern.”

The implications were disturbing, he added, “You’re giving this vaccine to prevent neonatal death.” Though the Pfizer vaccine that was granted approval had a very slight increase in premature birth, the risk wasn’t statistically significant, he pointed out, “and it showed similar benefits in preventing neonatal illness, which can be fatal.”

Dr. Glatt said that there is still a lingering concern with the approved vaccine, and he explained that most clinicians will give it closer to the end of the recommended time window of 34 weeks. “This way, even if there is a slight increase in premature term labor, you’re probably not going to have a serious outcome because the baby will be far enough along.”

A difference in the incidence of preterm birth between the experimental vaccine and placebo groups was predominantly found in low- and middle-income countries, according to Dieussaert’s team, “where approximately 50% of the trial population was enrolled and where the medical need for maternal RSV vaccines is the greatest.”

The RR was 1.56 (95% CI, 1.17-2.10) for low- and middle-income countries and 1.04 (95% CI, 0.68-1.58) for high-income countries. 

“If a smaller percentage of participants from low- and middle-income countries had been enrolled in our trial, the RR for preterm birth in the vaccine group as compared with the placebo group might have been reduced in the overall trial population,” they reported.

The authors explained that the data do not reveal the cause of the higher risk for preterm birth in the vaccine group.

“We do not know what caused the signal,” the company’s spokesperson added. “GSK completed all the necessary steps of product development including preclinical toxicology studies and clinical studies in nonpregnant women prior to starting the studies in pregnant women. There were no safety signals identified in any of the earlier parts of the clinical testing. There have been no safety signals identified in the other phase 3 trials for this vaccine candidate.”

Skipping meals, mood and anxiety disorders, as well as vaping and substance use, all raise the risk for frequent recurrent headaches in children and adolescents, new data from a population-based study showed.

Children and teens with anxiety or mood disorders had twice the risk for frequent headaches, defined as occurring once or more per week, and those who regularly ate breakfast and dinners with their family had an 8% lower risk for frequent headaches than those who did not eat regular meals.

“It is not uncommon for children and teens to have headaches, and while medications are used to stop and sometimes prevent headaches, lifestyle changes also may offer an effective route to relief by preventing headaches from happening and improving quality of life,” study investigator Serena L. Orr, MD, MSc, University of Calgary in Alberta, Canada, said in a press release.

The findings were published online in Neurology.
 

Negative Consequences

Previous research shows frequent recurrent headaches occur in up to 30% of children and adolescents and can lead to lower academic achievement and lower quality of life.

Treatment recommendations often focus on adjusting lifestyle behaviors, such as sleep and meal timing or smoking.

To further investigate these links, researchers used data from the 2019 Canadian Health Survey on Children and Youth and included about 5 million children and teens aged 5-17 years. In most cases, a parent or guardian answered the survey questions.

In addition to assessing participants for headache frequency in the past week, the survey included questions about how often they had breakfast, were physically active, or spent playing video games or with a mobile device, for instance. Parents/guardians were also asked whether the youth had ever been diagnosed with a mood or anxiety disorder.

For participants aged between 12 and 17 years, there were also questions about smoking, alcohol consumption, and substance use.

The mean age of participants was 11 years, and 48% were female. About 6% of the participants had frequent recurrent headaches.

Investigators found that meal regularity was inversely associated with frequent headaches (P < .001). In an adjusted model, youth who often ate breakfast and dinner with their families had an 8% lower risk for frequent headaches than those who didn’t dine with their families regularly.

“It is possible regular family meals may lead to greater connectedness and communication within the family and better mental health outcomes, which in turn may impact headache frequency,” Dr. Orr noted.

Youth who spent more than 21 hours per week in front of computer screens or with video games had higher odds for frequent headaches (P < .001), but this association did not survive statistical adjustment for demographics or lifestyle factors.

Both mood and anxiety disorders were associated with twice the risk for frequent headaches, and this risk survived adjustment for age, sex, household income, and other lifestyle factors.

In adolescents aged 12-17 years, there was an association between drinking alcohol and frequent headache, with higher alcohol consumption increasing the likelihood of frequent headache. For instance, those who drank once or more per week had three times the risk for frequent headache (P < .001), and those who indulged in binge drinking at least five times per month had five times the risk for frequent headache (P < .001).

Smoking cannabis was also associated with frequent headache in a dose-dependent manner. Daily users had a threefold increased risk for frequent headache vs those who didn’t use cannabis (P < .001).

Similarly, those who smoked or used e-cigarettes daily also had a threefold increased risk for frequent headaches versus nonusers.

One of the study’s limitations was that it didn’t include participants living in foster homes, institutions or on First Nation reserves. Investigators also were not able to determine headache type and did not assess hydration, which can be an important lifestyle factor in headache etiology.
 

Prioritize Questions About Lifestyle?

In an accompanying editorial, Irene Patniyot, MD, of Baylor College of Medicine in Houston, Texas, noted that lifestyle advice is an important part of managing headache disorders in children and youth and questioned whether neurologists should prioritize discussions about lifestyle habits in this patient population. However, she noted, given the heavy demands on neurologists’ time, this may be “idealistic.”

One potential solution may lie in automating electronic questionnaires for inclusion in patients’ medical records. “Data extraction from electronic questionnaires has already led to new data on symptoms associated with headache in youth and can potentially lead to earlier identification and treatment of mental health disorders and lifestyle habits that negatively affect headache burden and overall well-being,” Dr. Patniyot wrote.

The study was funded by the Social Sciences and Humanities Research Council of Canada, the Canadian Institutes of Health Research, the Canada Foundation for Innovation, and Statistics Canada. Dr. Orr reported receiving royalties from Cambridge University Press; serving on the editorial boards of Headache, Neurology, and the American Migraine Foundation; and receiving research funding from the Canadian Institutes of Health Research and the Alberta Children’s Hospital Research Institute. Other disclosures were noted in the original article.
