WASHINGTON – A nonpharmacologic, interdisciplinary program significantly improved chronic pain in children and the quality of life for their families, based on data from 115 individuals.

Up to 40% of children experience chronic pain that affects their physical, psychosocial, and educational functioning, said Jessica Campanile, BA, a medical student at the University of Pennsylvania, Philadelphia, in a presentation at the Pediatric Academic Societies annual meeting.

Although interdisciplinary pediatric pain rehabilitation programs have shown positive outcomes, very few use only nonpharmacologic treatments, said Ms. Campanile. In addition, few studies have explored the effects of a hospital-based program on the patients and their families.

Ms. Campanile and colleagues conducted a retrospective cohort study of participants in an outpatient pain rehabilitation program at the Children’s Hospital of Philadelphia between April 2016 and December 2019. Patients were evaluated by a pediatric rheumatologist, psychologist, and physical and occupational therapists.

Patients engaged in 2-3 hours of physical therapy (PT) and 2-3 hours of occupational therapy (OT) in a 1:1 ratio at least 5 days a week. Physical activities included stepping into and out of a tub, carrying laundry, and desensitizing to allodynia as needed. Participants also received individual and group cognitive-behavior therapy interventions from psychologists, and psychological support during PT and OT sessions if needed. Parents/caregivers were invited to separate individual and group therapy sessions as part of the program. The median age at admission to the program was 15 years, and 79% of the participants were female. Patients participated the program for a median of 17 days, and 87% were outpatients who came to the hospital for the program.

Pain was assessed based on the 0-10 verbal pain intensity scale, energy was assessed on a scale of 0-100, and functional disability was assessed on a scale of 0-60, with higher scores indicating more pain, more energy, and more self-perceived disability, respectively.

Overall, scores on measures of pain, disability, allodynia, and energy improved significantly from baseline to discharge from the program. Verbal pain intensity scores decreased on average from 7 to 5, disability scores decreased from 26 to 9, the proportion of patients reporting allodynia decreased from 86% to 61%, and the energy level score increased from 70 to 77. The trend continued at the first follow-up visit, conducted 2-3 months after discharge from the program. Notably, pain intensity further decreased from a median of 5 at program completion to a median of 2 at the first follow-up, Ms. Campanile said. Improvements in allodynia also were sustained at the first follow-up.

Quality of life measures related to physical, emotional, social, and cognitive function also improved significantly from baseline to completion of the program.

In addition, scores on a quality of life family impact survey improved significantly; in particular, parent health-related quality of life scores (Parent HRQoL) improved from 60 at baseline to 71 at the end of the program on a scale of 0 to 100. The study findings were limited by several factors including the relatively short duration and use of a convenience sample from a retrospective cohort, with data limited to electronic health records, Ms. Campanile said. The study also was not powered to examine differential treatments based on psychiatric conditions, and any psychiatric conditions were based on self-reports.

However, the results support the value of a nonpharmacologic interdisciplinary program as “a robust treatment for youth with chronic idiopathic pain, for both patients and the family unit,” she said.

“This study also supports the need for and benefit of additional counseling for patients and their caregivers prior to and during enrollment in a pain rehabilitation program,” she concluded.
 

Study supports effectiveness of drug-free pain management

“The management of pain in any age group can be challenging, especially with current concerns for opioid dependence and abuse,” Cathy Haut, DNP, CPNP-AC, CPNP-PC, a pediatric nurse practitioner in Rehoboth Beach, Del., said in an interview.

“Chronic pain affects daily life for all populations, but for children, adolescents, and their families, it can have a long-lasting impact on growth and development, psychosocial and physical well-being,” Dr. Haut said. “Determining and testing nonpharmacologic alternative methods of pain control are extremely important.”

Given the debilitating effects of chronic pain, and the potential side effects and dependence that have been associated with use of pharmacologic modes of pain control, unique and creative solutions have begun to emerge and need further attention and study, she said.

However, “despite published research supporting the use of alternative and complementary approaches to pain control in children and adolescents, nonpharmacologic, collaborative, interprofessional approaches to pain control have not been widely shared in the literature,” she said.

“Barriers to this type of program include first and foremost a potential lack of financial and workforce-related resources,” Dr. Haut said. “Patient and family attendance at frequent health visits, daily or even every other day, may also hinder success, but opportunities for telehealth and family training to learn physical and occupational skills within this type of program may be beginning solutions.”

Additional research should be conducted at multiple children’s hospitals, with a larger number of children and adolescents at varying ages, with pain related to different diagnoses, and with the inclusion of collaborative methodology, said Dr. Haut. “The current study had some limitations, including the small sample size, predominantly female sex, and a short participation time frame utilizing retrospective review. Completing prospective research over a longer time frame can also yield generalizable results applicable to varied populations.”

The study received no outside funding. Ms. Campanile had no financial conflicts to disclose. Dr. Haut had no financial conflicts to disclose, and serves on the editorial advisory board of Pediatric News.

Dysphagia treatment may be a way to reduce risk for chronic obstructive pulmonary disease (COPD) exacerbations, according to Yoshitaka Oku, MD, of Hyogo Medical University, Nishinomiya, Japan.

Gastroesophageal regurgitation disease (GERD) is known to be associated with exacerbations in COPD, but previous studies have shown little impact of standard GERD therapy on COPD exacerbations. However, additional research indicates that delayed swallowing contributes to COPD exacerbations, as reported in a research review.

In an article published recently in Respiratory Physiology & Neurobiology, Dr. Oku hypothesized that swallowing abnormalities are a confounding factor in the association between GERD and COPD exacerbation, and that counteracting swallowing disorders may reduce COPD exacerbations.

Swallowing disorder (dysphagia) is a common comorbidity in patients with COPD and has been reported at a 17%-20% greater prevalence in those with COPD, compared with controls, the researchers said.

Patients with COPD have altered swallowing behavior because of several factors, including decreased maximal laryngeal elevation, Dr. Oku said. Individuals with COPD “are also prone to laryngeal penetration and aspiration when swallowing large volumes of liquid and tend to follow an inspiratory-swallow-expiratory (I-SW-E) pattern when swallowing large volumes,” he explained.

Dr. Oku conducted prospective studies to investigate the impact of breathing-swallowing discoordination on COPD exacerbation. He found that discoordination in swallowing patterns and the inability to produce airway protective mechanism (such as the I-SW-E pattern) may contribute to more frequent aspirations and more frequent exacerbations.

Dr. Oku also examined whether CPAP and bilevel positive airway pressure (BiPAP) might affect breathing-swallowing coordination in healthy controls and patients with COPD. They found a decrease in breathing-swallowing coordination with CPAP, but not BiPAP, in both controls and stable COPD patients. “During BiPAP, a brief negative flow associated with relaxation of the pharyngeal constrictor muscle triggers inspiratory support, which results in the SW-I pattern,” Dr. Oku noted.

Dr. Oku also wrote that interferential current stimulation (IFC) has been used to stimulate muscles. Studies of transcutaneous electrical sensory stimulation using IFC (IFC-TESS) as an intervention to improve swallowing have shown some success, and also may improve airway protection.

“However, its safety and efficacy in patients with COPD remains unknown,” he wrote. Dr. Oku conducted a study of stable COPD patients and found that repeated salivary swallow test (RSST) scores improved significantly after an IFC-TESS intervention.

Breathing-swallowing discoordination may be an early indicator of swallowing disorder in COPD, and interventions can improve these disorders, Dr. Oku added. However, more research is needed to explore whether interventions to improve dysphagia reduce the frequency of exacerbations in COPD patients, he concluded.

The study was supported by a grant from JSPS KAKENHI. Dr. Oku serves as a senior managing director at EuSense Medical Co.

WASHINGTON – Congenital diaphragmatic hernia affects many areas of pediatrics. In a trio of posters presented at the Pediatric Academic Societies annual meeting, researchers at Children’s Hospital of Philadelphia addressed initial ventilation and infant outcomes in the neonatal intensive care unit, prenatal brain immaturity and later cognitive development, and antibiotic use.

Initial ventilation mode shows little impact on NICU outcomes

In one study, K. Taylor Wild, MD, and colleagues investigated whether high-frequency oscillatory ventilation (HFOV) as an initial mode of ventilation in the delivery room improved gas exchange and neonatal ICU (NICU) outcomes in infants with congenital diaphragmatic hernia (CDH), compared with conventional mechanical ventilation (CMV). In 2019, HFOV became standard practice at CHOP.

The researchers reviewed data on infants with severe CDH who were born at CHOP between 2014 and 2022. Of these, 75 were placed on HFOV and 114 on CMV. The mean gestational age at birth in both groups was approximately 38 weeks, and the mean birth weight was approximately 3 kg.

Compared with CMV, use of HFOV in the delivery room was associated with significantly higher pH (7.05 vs. 7.16, P = .03) and significantly lower CO₂ (85.2 vs. 64.5, P = .005). However, after adjusting for CDH severity, no significant differences appeared in length of stay and overall survival to discharge. The higher rates of extracorporeal membrane oxygenation (ECMO) use in the HFOV group, compared with the CMV group (48% vs. 29.9%), may reflect more severe disease, the researchers noted.
 

Prenatal brain immaturity associates with developmental delay

In a second study, Sandy Johng, MD, and colleagues found a significant association between prenatal brain immaturity in babies with CDH and developmental scores at age 12 months and older. The researchers reviewed data from a single-center patient registry for 48 infants for whom prenatal neuroimaging results were available. Based on the imaging, a fetal Total Maturation Score (fTMS) was generated and used as a measure of prenatal brain immaturity.

Results from the Bayley Scales of Infant Development-III (BSID-III) – a composite of cognitive, motor, and language scores – were available for 26 neonates at ages 12 months and under as well as at 12 months and older.

In a linear regression model, the researchers found a significant association between difference in fTMS and BSID-III composite language scores in infants 12 months and older. After adjusting for ECMO treatment, an increase in fTMS of one unit was associated with a 6.5-point increase in language scores at age 12 months and older (P < .01). No significant differences were observed between fTMS difference and language scores in infants under 12 months, or in cognitive or motor scores at any age, the researchers noted. The findings were limited by the small sample size, but the study is the first to show an association between prenatal imaging and neurodevelopmental outcomes for infants with CDH. Results suggest that the risk for neurodevelopmental impairment in this population may start in utero, the researchers concluded.
 

Antibiotic use stays stable

In a third study, Sabrina Flohr, MPH, and colleagues reviewed antibiotic use among infants with CDH who are at increased risk for infection. In many cases, distinguishing between infection and inherent clinical illness is challenging and may lead to unnecessarily high rates of antibiotic use, the researchers noted.

They reviewed data from 381 infants with CDH born at CHOP between January 2013 and November 2022 who were treated and survived in the NICU. Overall, 97.1% of the newborns received antibiotics for a median of 13 days. Nearly two-thirds (63.5%) received antibiotics in the first 72 hours, and 98.1% received them after 72 hours. Ampicillin and gentamicin were the antibiotics used most often in the first 72 hours (approximately 50% for both). After 72 hours, the most commonly used antibiotics were cefazolin (91.6%), vancomycin (67.7%), and cefepime (65.7%).

The results show that antibiotic use among newborns with CDH did not change significantly over time, and the choices of later antibiotics likely reflect perioperative prophylaxis and broad-spectrum treatment, the researchers noted.
 

Studies show larger trends

“These are three interesting studies regarding congenital diaphragmatic hernia from a center that does a high volume of repairs,” said Tim Joos, MD, a Seattle-based clinician with a combination internal medicine/pediatrics practice, in an interview.

“Each individual case can be consuming, but it is important to look for an aggregate of cases to see the larger trends in practices and outcomes,” said Dr. Joos, who was not involved in any of the studies.

The findings of the ventilation study surprised Dr. Joos. “Although high-frequency oscillatory ventilation improves initial gas exchange in the delivery room, compared with conventional mechanical ventilation, it was not associated with any larger NICU outcome,” he said. “This surprised me because my intuition would be that the HFOV would lead to less barotrauma and therefore better outcomes with the underformed lungs associated with this disorder.”

The imaging study demonstrates the need for more research on the association between CDH and neurologic outcomes, said Dr. Joos.

“Prenatal neuroimaging that shows delayed maturation with congenital diaphragmatic hernia correlates with lower language scores in early childhood, and suggests that this may be a predictor of neurologic outcome independent of the postnatal course,” he said.

Data from the antibiotics study reflect current trends, said Dr. Joos. “Antibiotics use is extremely common during the postnatal course of CDH and surgical repair,” he said. “The choice of antibiotics mirrors what we see in other neonatal conditions with regard to treatment for possible early neonatal sepsis, postsurgical prophylaxis, and later broad-spectrum empiric coverage,” he noted.

“I look forward to more studies to come out of large-volume centers like CHOP or aggregated results from many centers to help figure out best practices for this rare but very complicated and often devastating malformation,” he said.

The three posters received no outside funding. The researchers had no financial conflicts to disclose. Dr. Joos had no financial conflicts to disclose, but he serves on the Editorial Advisory Board of Pediatric News.

Overall, 97.1% of the newborns received antibiotics for a median of 13 days. Nearly two-thirds (63.5%) received antibiotics in the first 72 hours, and 98.1% received them after 72 hours. Ampicillin and gentamicin were the antibiotics used most often in the first 72 hours (approximately 50% for both). After 72 hours, the most commonly used antibiotics were cefazolin (91.6%), vancomycin (67.7%), and cefepime (65.7%).

The results show that antibiotic use among newborns with CDH did not change significantly over time, and the choices of later antibiotics likely reflect perioperative prophylaxis and broad-spectrum treatment, the researchers noted.
 

Studies show larger trends

“These are three interesting studies regarding congenital diaphragmatic hernia from a center that does a high volume of repairs,” said Tim Joos, MD, a Seattle-based clinician with a combination internal medicine/pediatrics practice, in an interview.

“Each individual case can be consuming, but it is important to look for an aggregate of cases to see the larger trends in practices and outcomes,” said Dr. Joos, who was not involved in any of the studies.

The findings of the ventilation study surprised Dr. Joos. “Although high-frequency oscillatory ventilation improves initial gas exchange in the delivery room, compared with conventional mechanical ventilation, it was not associated with any larger NICU outcome,” he said. “This surprised me because my intuition would be that the HFOV would lead to less barotrauma and therefore better outcomes with the underformed lungs associated with this disorder.”

The imaging study demonstrates the need for more research on the association between CDH and neurologic outcomes, said Dr. Joos.

“Prenatal neuroimaging that shows delayed maturation with congenital diaphragmatic hernia correlates with lower language scores in early childhood, and suggests that this may be a predictor of neurologic outcome independent of the postnatal course,” he said.

Data from the antibiotics study reflect current trends, said Dr. Joos. “Antibiotics use is extremely common during the postnatal course of CDH and surgical repair,” he said. “The choice of antibiotics mirrors what we see in other neonatal conditions with regard to treatment for possible early neonatal sepsis, postsurgical prophylaxis, and later broad-spectrum empiric coverage,” he noted.

“I look forward to more studies to come out of large-volume centers like CHOP or aggregated results from many centers to help figure out best practices for this rare but very complicated and often devastating malformation,” he said.

The three posters received no outside funding. The researchers had no financial conflicts to disclose. Dr. Joos had no financial conflicts to disclose, but he serves on the Editorial Advisory Board of Pediatric News.

WASHINGTON – Congenital diaphragmatic hernia affects many areas of pediatrics. In a trio of posters presented at the Pediatric Academic Societies annual meeting, researchers at Children’s Hospital of Philadelphia addressed initial ventilation and infant outcomes in the neonatal intensive care unit, prenatal brain immaturity and later cognitive development, and antibiotic use.

Initial ventilation mode shows little impact on NICU outcomes

In one study, K. Taylor Wild, MD, and colleagues investigated whether high-frequency oscillatory ventilation (HFOV) as an initial mode of ventilation in the delivery room improved gas exchange and neonatal ICU (NICU) outcomes in infants with congenital diaphragmatic hernia (CDH), compared with conventional mechanical ventilation (CMV). In 2019, HFOV became standard practice at CHOP.

The researchers reviewed data on infants with severe CDH who were born at CHOP between 2014 and 2022. Of these, 75 were placed on HFOV and 114 on CMV. The mean gestational age at birth in both groups was approximately 38 weeks, and the mean birth weight was approximately 3 kg.

Compared with CMV, use of HFOV in the delivery room was associated with significantly higher pH (7.05 vs. 7.16, P = .03) and significantly lower CO₂ (85.2 vs. 64.5, P = .005). However, after adjusting for CDH severity, no significant differences appeared in length of stay and overall survival to discharge. The higher rates of extracorporeal membrane oxygenation (ECMO) use in the HFOV group, compared with the CMV group (48% vs. 29.9%), may reflect more severe disease, the researchers noted.
 

Prenatal brain immaturity associates with developmental delay

In a second study, Sandy Johng, MD, and colleagues found a significant association between prenatal brain immaturity in babies with CDH and developmental scores at age 12 months and older. The researchers reviewed data from a single-center patient registry for 48 infants for whom prenatal neuroimaging results were available. Based on the imaging, a fetal Total Maturation Score (fTMS) was generated and used as a measure of prenatal brain immaturity.

Results from the Bayley Scales of Infant Development-III (BSID-III) – a composite of cognitive, motor, and language scores – were available for 26 neonates at ages 12 months and under as well as at 12 months and older.

In a linear regression model, the researchers found a significant association between difference in fTMS and BSID-III composite language scores in infants 12 months and older. After adjusting for ECMO treatment, an increase in fTMS of one unit was associated with a 6.5-point increase in language scores at age 12 months and older (P < .01). No significant differences were observed between fTMS difference and language scores in infants under 12 months, or in cognitive or motor scores at any age, the researchers noted. The findings were limited by the small sample size, but the study is the first to show an association between prenatal imaging and neurodevelopmental outcomes for infants with CDH. Results suggest that the risk for neurodevelopmental impairment in this population may start in utero, the researchers concluded.
 

Antibiotic use stays stable

In a third study, Sabrina Flohr, MPH, and colleagues reviewed antibiotic use among infants with CDH who are at increased risk for infection. In many cases, distinguishing between infection and inherent clinical illness is challenging and may lead to unnecessarily high rates of antibiotic use, the researchers noted.

They reviewed data from 381 infants with CDH born at CHOP between January 2013 and November 2022 who were treated and survived in the NICU. Overall, 97.1% of the newborns received antibiotics for a median of 13 days. Nearly two-thirds (63.5%) received antibiotics in the first 72 hours, and 98.1% received them after 72 hours. Ampicillin and gentamicin were the antibiotics used most often in the first 72 hours (approximately 50% for both). After 72 hours, the most commonly used antibiotics were cefazolin (91.6%), vancomycin (67.7%), and cefepime (65.7%).

Diabetes devices represent a major advancement in the management of diabetes, but they can cause skin reactions that affect patient adherence and quality of life, Jennifer K. Chen, MD, said in a presentation at the annual meeting of the American Contact Dermatitis Society.

Advanced technologies used for the management of diabetes fall into three main categories, said Dr. Chen, of the department of dermatology, Stanford University, Redwood City, Calif. Continuous glucose monitoring (CGM) devices, which are worn on the body, collect glucose measurements. Continuous subcutaneous insulin infusion (CSII) devices are attached to the body via an infusion set and are now available as tubing-free patch pumps that are attached directly to the skin via a catheter. Glucose-responsive insulin delivery systems combine the sensing and delivery features of the other two types of devices.

Dr. Chen

Once thought to be rare, reports of skin complications related to diabetes devices have been increasing in recent years, she said. Some reports suggest that at any given time, skin complications may affect as many as one quarter to one half of patients who use these devices, “so this is an important issue,” she emphasized. “Skin reactions are a major factor in device discontinuation, so we as clinicians need to be really proactive about treating these reactions.”

Risk factors for skin complications related to diabetes devices include sensitization to the adhesive used with the devices, as well as prolonged exposure to the device, Dr. Chen said. Younger age also appears to be a risk factor, as is a compromised skin barrier in the area where the device is used.

Unfortunately, obtaining details on the specific adhesives and the raw materials used in these devices, so as to customize patch testing, remains a challenge, she said. “Patch testing initially was often negative to commercially available allergens, even while patients were testing positive to pieces of device adhesive,” she noted.
 

Consider isobornyl acrylate

An article published in 2017 in Contact Dermatitis was “a major breakthrough” in that it identified isobornyl acrylate (IBOA) as an allergen in connection with the Freestyle Libre, a CGM device that was relatively new at the time. The finding was serendipitous, Dr. Chen said. A patient being treated for suspected allergic contact dermatitis in connection with use of a Freestyle Libre device was tested for IBOA accidentally, after the nurse administering the patch test thought that this was part of the standard acrylate series, she explained.

Subsequently, researchers identified 15 patients who had experienced reactions to the Freestyle Libre; 12 of 13 patients who were patch tested for IBOA tested positive. IBOA was found throughout the device, particularly where the top and bottom plastic components were connected, Dr. Chen said. This suggested that the IBOA was in the device housing and had diffused into the adhesive that attached the device to the skin.

An article published in 2018 in the Journal of Diabetes Science described three patients who developed severe allergic contact dermatitis from IBOA while using a CGM device, Dr. Chen said. The investigators confirmed that there were no reactions to the adhesive itself, again suggesting that IBOA had diffused into the adhesive from other parts of the device.

Although the authors were bound by a confidentiality agreement regarding the individual adhesive components, “the authors noted most of the acrylates in the adhesive were not present in commercially available acrylate series for patch testing,” she said.

IBOA, the ACDS’ Allergen of the Year in 2020, is common in sealants, glues, and adhesives, Dr. Chen said. Although IBOA had been reported infrequently as an allergen, it has now been identified as a “potential culprit” behind skin reactions in many diabetes devices, including CSII and CGM devices, she added.

In addition, N,N-dimethylacrylamide (DMAA) is an allergen that has been identified in several diabetes devices and often occurs with IBOA in medical-grade UV-cured adhesives, Dr. Chen noted. Other allergens identified in diabetes devices include colophony, which is present in many adhesives, as well as other acrylates and epoxy resin.

Diabetes devices are constantly evolving. IBOA is no longer found in Freestyle Libre devices. It is important that clinicians stay up to date with the medical literature and advocate for partnership with device manufacturers, she emphasized.
 

Patch testing

When diabetes devices are suspected as the source of allergic contact dermatitis, a minimum of a baseline series that contains colophony at a concentration of 20% in petrolatum should be carried out, Dr. Chen said. Commercialized patch test trays, which include plastics, glues, acrylates, epoxy resins/isocyanates, and colophony derivatives, should be ideal. “Personal-care products should be included if they are potentially relevant,” she added.

Dr. Chen shared tables published in Contact Dermatitis in 2021 with examples of screening test series. She said to consider including screening for other allergens more recently discovered in diabetes devices, including 2,2’-methylenebis(6-tert-butyl-4-methylphenol) monoacrylate (MBPA) 1.5% pet; dipropylene glycol diacrylate (DPGDA) 0.1% pet; and butylated hydroxytoluene (BHT) 2% pet.

Testing for monomethyl ether of hydroquinone should also be considered; this may be included in the test preparations for IBOA and DMAA.
 

Management strategies

For patients who experience skin reactions to their diabetes devices, consideration may given to relocating the device to another area of skin or changing sensors more frequently, according to Dr. Chen.

For some patients, the reaction can be managed with corticosteroid cream, ointment, solution, or nasal spray. Topical antibiotics or topical antihistamines can be helpful, as can barrier dressings, solutions, or sprays, she said. The best solution is to change to a device that does not have the culprit allergen, “but that is difficult, since we don’t know what is in these devices,” she added. Good alternatives include the Eversense CGM device or devices that have been demonstrated not to contain IBOA, such as the Freestyle Libre 2 or the newer version of the Omnipod, an insulin delivery system

Looking ahead, Dr. Chen said that “mandatory labeling is needed, as devices with the same name may have different compositions, depending on the date of manufacture.” Allergens relevant to people with diabetes are constantly evolving, and many are still unidentified, so clinicians and manufacturers need to work together to identify the culprit allergens and their sources, she said.

Dr. Chen has served as principal investigator or subinvestigator for Amgen, AbbVie, and Sanofi Regeneron and as a consultant for Purity Brands.

Consider popular nutritional supplements as a potential source of allergic reactions if the cause of the reaction is otherwise unknown, Alison Ehrlich, MD, said at the annual meeting of the American Contact Dermatitis Society.

Sherri Holdridge

Allergens may be hidden in a range of supplement products, from colorings in vitamin C powders to some vitamins used in hair products and other products.

“In general, our patients do not tell us what supplements they are taking,” said Dr. Ehrlich, a dermatologist who practices in Washington, D.C. Antiaging, sleep, and weight loss/weight control supplements are among the most popular, she said.

Surveys have shown that many patients do not discuss supplement use with their health care providers, in part because they believe their providers would disapprove of supplement use, and patients are not educated about supplements, she said. “This is definitely an area that we should try to learn more about,” she added.

Current regulations regarding dietary supplements stem from the Dietary Supplement Health and Education Act of 1994, which defined dietary supplements as distinct from meals but regulated them as a category of food, not as medications. Dietary supplements can be vitamins, minerals, herbs, and extracts, Dr. Ehrlich said.

“There is not a lot of safety wrapped around how supplements come onto the market,” she explained. “It is not the manufacturer’s responsibility to test these products and make sure they are safe. When they get pulled off the market, it is because safety reports are getting back to the FDA.”

Consequently, a detailed history of supplement use is important, as it may reveal possible allergens as the cause of previously unidentified reactions, she said.

Dr. Ehrlich shared a case involving a patient who claimed to have had a reaction to a “Prevage-like” product that was labeled as a crepe repair cream. Listed among the product’s ingredients was idebenone, a synthetic version of the popular antioxidant known as Coenzyme Q.
 

Be wary of vitamins

Another potential source of allergy is vitamin C supplements, which became especially popular during the pandemic as people sought additional immune system support, Dr. Ehrlich noted. “What kind of vitamin C product our patients are taking is important,” she said. For example, some vitamin C powders contain coloring agents, such as carmine. Some also contain gelatin, which may cause an allergic reaction in individuals with alpha-gal syndrome, she added.

Sally Koch Kubetin/MDedge News

In general, water-soluble vitamins such as vitamins B1 to B9, B12, and C are more likely to cause an immediate reaction, Dr. Ehrlich said. Fat-soluble vitamins, such as vitamins A, D, E, and K, are more likely to cause a delayed reaction of allergic contact dermatitis.

Dr. Ehrlich described some unusual reactions to vitamins that have been reported, including a systemic allergy associated with vitamin B1 (thiamine), burning mouth syndrome associated with vitamin B3 (nicotinate), contact urticaria associated with vitamin B5 (panthenol), systemic allergy and generalized ACD associated with vitamin E (tocopherol), and erythema multiforme–like ACD associated with vitamin K1.

Notably, vitamin B5 has been associated with ACD as an ingredient in hair products, moisturizers, and wound care products, as well as B-complex vitamins and fortified foods, Dr. Ehrlich said.

Herbs and spices can act as allergens as well. Turmeric is a spice that has become a popular supplement ingredient, she said. Turmeric and curcumin (found in turmeric) can be used as a dye for its yellow color as well as a flavoring but has been associated with allergic reactions. Another popular herbal supplement, ginkgo biloba, has been marketed as a product that improves memory and cognition. It is available in pill form and in herbal teas.

“It’s really important to think about what herbal products our patients are taking, and not just in pill form,” Dr. Ehrlich said. “We need to expand our thoughts on what the herbs are in.”
 

Consider food additives as allergens

Food additives, in the form of colorants, preservatives, or flavoring agents, can cause allergic reactions, Dr. Ehrlich noted.

The question of whether food-additive contact sensitivity has a role in the occurrence of atopic dermatitis (AD) in children remains unclear, she said. However, a study published in 2020 found that 62% of children with AD had positive patch test reactions to at least one food-additive allergen, compared with 20% of children without AD. The additives responsible for the most reactions were azorubine (24.4%); formic acid (15.6%); and carmine, cochineal red, and amaranth (13.3% for each).

Common colorant culprits in allergic reactions include carmine, annatto, tartrazine, and spices (such as paprika and saffron), Dr. Ehrlich said. Carmine is used in meat to prevent photo-oxidation and to preserve a red color, and it has other uses as well, she said. Carmine has been associated with ACD, AD flares, and immediate hypersensitivity. Annatto is used in foods, including processed foods, butter, and cheese, to provide a yellow color. It is also found in some lipsticks and has been associated with urticaria and angioedema, she noted.

Food preservatives that have been associated with allergic reactions include butylated hydroxyanisole and sulfites, Dr. Ehrlich said. Sulfites are used to prevent food from turning brown, and it may be present in dried fruit, fruit juice, molasses, pickled foods, vinegar, and wine.

Reports of ACD in response to sodium metabisulfite have been increasing, she noted. Other sulfite reactions may occur with exposure to other products, such as cosmetics, body washes, and swimming pool water, she said.

Awareness of allergens in supplements is important “because the number of our patients taking supplements for different reasons is increasing” and allergens in supplements could account for flares, Dr. Ehrlich said. Clinicians should encourage patients to tell them what supplements they use. Clinicians should review the ingredients in these supplements with their patients to identify potential allergens that may be causing reactions, she advised.

Dr. Ehrlich has disclosed no relevant financial relationships.

Dietary supplements can be vitamins, minerals, herbs, and extracts, Dr. Ehrlich said.

“There is not a lot of safety wrapped around how supplements come onto the market,” she explained. “It is not the manufacturer’s responsibility to test these products and make sure they are safe. When they get pulled off the market, it is because safety reports are getting back to the FDA.”

Consequently, a detailed history of supplement use is important, as it may reveal possible allergens as the cause of previously unidentified reactions, she said.

Dr. Ehrlich shared a case involving a patient who claimed to have had a reaction to a “Prevage-like” product that was labeled as a crepe repair cream. Listed among the product’s ingredients was idebenone, a synthetic version of the popular antioxidant known as Coenzyme Q.
 

Be wary of vitamins

Another potential source of allergy is vitamin C supplements, which became especially popular during the pandemic as people sought additional immune system support, Dr. Ehrlich noted. “What kind of vitamin C product our patients are taking is important,” she said. For example, some vitamin C powders contain coloring agents, such as carmine. Some also contain gelatin, which may cause an allergic reaction in individuals with alpha-gal syndrome, she added.

In general, water-soluble vitamins such as vitamins B1 to B9, B12, and C are more likely to cause an immediate reaction, Dr. Ehrlich said. Fat-soluble vitamins, such as vitamins A, D, E, and K, are more likely to cause a delayed reaction of allergic contact dermatitis.

Dr. Ehrlich described some unusual reactions to vitamins that have been reported, including a systemic allergy associated with vitamin B1 (thiamine), burning mouth syndrome associated with vitamin B3 (nicotinate), contact urticaria associated with vitamin B5 (panthenol), systemic allergy and generalized ACD associated with vitamin E (tocopherol), and erythema multiforme–like ACD associated with vitamin K1.

Notably, vitamin B5 has been associated with ACD as an ingredient in hair products, moisturizers, and wound care products, as well as B-complex vitamins and fortified foods, Dr. Ehrlich said.

Herbs and spices can act as allergens as well. Turmeric is a spice that has become a popular supplement ingredient, she said. Turmeric and curcumin (found in turmeric) can be used as a dye for its yellow color as well as a flavoring but has been associated with allergic reactions. Another popular herbal supplement, ginkgo biloba, has been marketed as a product that improves memory and cognition. It is available in pill form and in herbal teas.

“It’s really important to think about what herbal products our patients are taking, and not just in pill form,” Dr. Ehrlich said. “We need to expand our thoughts on what the herbs are in.”
 

Consider food additives as allergens

Food additives, in the form of colorants, preservatives, or flavoring agents, can cause allergic reactions, Dr. Ehrlich noted.

The question of whether food-additive contact sensitivity has a role in the occurrence of atopic dermatitis (AD) in children remains unclear, she said. However, a study published in 2020 found that 62% of children with AD had positive patch test reactions to at least one food-additive allergen, compared with 20% of children without AD. The additives responsible for the most reactions were azorubine (24.4%); formic acid (15.6%); and carmine, cochineal red, and amaranth (13.3% for each).

Common colorant culprits in allergic reactions include carmine, annatto, tartrazine, and spices (such as paprika and saffron), Dr. Ehrlich said. Carmine is used in meat to prevent photo-oxidation and to preserve a red color, and it has other uses as well, she said. Carmine has been associated with ACD, AD flares, and immediate hypersensitivity. Annatto is used in foods, including processed foods, butter, and cheese, to provide a yellow color. It is also found in some lipsticks and has been associated with urticaria and angioedema, she noted.

Food preservatives that have been associated with allergic reactions include butylated hydroxyanisole and sulfites, Dr. Ehrlich said. Sulfites are used to prevent food from turning brown, and it may be present in dried fruit, fruit juice, molasses, pickled foods, vinegar, and wine.

Reports of ACD in response to sodium metabisulfite have been increasing, she noted. Other sulfite reactions may occur with exposure to other products, such as cosmetics, body washes, and swimming pool water, she said.

Awareness of allergens in supplements is important “because the number of our patients taking supplements for different reasons is increasing” and allergens in supplements could account for flares, Dr. Ehrlich said. Clinicians should encourage patients to tell them what supplements they use. Clinicians should review the ingredients in these supplements with their patients to identify potential allergens that may be causing reactions, she advised.

Dr. Ehrlich has disclosed no relevant financial relationships.

Allergens may be hidden in a range of supplement products, from colorings in vitamin C powders to some vitamins used in hair products and other products.

“In general, our patients do not tell us what supplements they are taking,” said Dr. Ehrlich, a dermatologist who practices in Washington, D.C. Antiaging, sleep, and weight loss/weight control supplements are among the most popular, she said.

Communities with easy access to fast food were 77% more likely to have high levels of obesity-related cancer mortality, based on data from a new cross-sectional study of more than 3,000 communities.

Although increased healthy eating has been associated with reduced risk of obesity and with reduced cancer incidence and mortality, access to healthier eating remains a challenge in communities with less access to grocery stores and healthy food options (food deserts) and/or easy access to convenience stores and fast food (food swamps), Malcolm Seth Bevel, PhD, of the Medical College of Georgia, Augusta, and colleagues, wrote in their paper, published in JAMA Oncology.

In addition, data on the association between food deserts and swamps and obesity-related cancer mortality are limited, they said.

“We felt that the study was important given the fact that obesity is an epidemic in the United States, and multiple factors contribute to obesity, especially adverse food environments,” Dr. Bevel said in an interview. “Also, I lived in these areas my whole life, and saw how it affected underserved populations. There was a story that needed to be told, so we’re telling it,” he said in an interview.

In a study, the researchers analyzed food access and cancer mortality data from 3,038 counties across the United States. The food access data came from the U.S. Department of Agriculture Food Environment Atlas (FEA) for the years 2012, 2014, 2015, 2017, and 2020. Data on obesity-related cancer mortality came from the Centers for Disease Control and Prevention for the years from 2010 to 2020.

Food desert scores were calculated through data from the FEA, and food swamp scores were based on the ratio of fast-food restaurants and convenience stores to grocery stores and farmers markets in a modification of the Retail Food Environment Index score.

The researchers used an age-adjusted, multiple regression model to determine the association between food desert and food swamp scores and obesity-related cancer mortality rates. Higher food swamp and food desert scores (defined as 20.0 to 58.0 or higher) were used to classify counties as having fewer healthy food resources. The primary outcome was obesity-related cancer mortality, defined as high or low (71.8 or higher per 100,000 individuals and less than 71.8 per 100,000 individuals, respectively).

Overall, high rates of obesity-related cancer mortality were 77% more likely in the counties that met the criteria for high food swamp scores (adjusted odds ratio 1.77). In addition, researchers found a positive dose-response relationship among three levels of both food desert scores and food swamp scores and obesity-related cancer mortality.

A total of 758 counties had obesity-related cancer mortality rates in the highest quartile. Compared to counties with low rates of obesity-related cancer mortality, counties with high rates of obesity-related cancer mortality also had a higher percentage of non-Hispanic Black residents (3.26% vs. 1.77%), higher percentage of adults older than 65 years (15.71% vs. 15.40%), higher rates of adult obesity (33.0% vs. 32.10%), and higher rates of adult diabetes (12.50% vs. 10.70%).

Possible explanations for the results include the lack of interest in grocery stores in neighborhoods with a population with a lower socioeconomic status, which can create a food desert, the researchers wrote in their discussion. “Coupled with the increasing growth rate of fast-food restaurants in recent years and the intentional advertisement of unhealthy foods in urban neighborhoods with [people of lower income], the food desert may transform into a food swamp,” they said.

The findings were limited by several factors including the study design, which did not allow for showing a causal association of food deserts and food swamps with obesity-related cancer mortality, the researchers noted. Other limitations included the use of groups rather than individuals, the potential misclassification of food stores, and the use of county-level data on race, ethnicity, and income, they wrote.

The results indicate that “food swamps appear to be a growing epidemic across the U.S., likely because of systemic issues, and should draw concern and conversation from local and state officials,” the researchers concluded.
 

Community-level investments can benefit individual health

Dr. Bevel said he was not surprised by the findings, as he has seen firsthand the lack of healthy food options and growth of unhealthy food options, especially for certain populations in certain communities. “Typically, these are people who have lower socioeconomic status, primarily non-Hispanic Black or African American or Hispanic American,” he said “I have watched people have to choose between getting fruits/vegetables versus their medications or running to fast food places to feed their families. What is truly surprising is that we’re not talking about people’s lived environment enough for my taste,” he said.  

“I hope that our data and results can inform local and state policymakers to truly invest in all communities, such as funding for community gardens, and realize that adverse food environments, including the barriers in navigating these environments, have significant consequences on real people,” said Dr. Bevel. “Also, I hope that the results can help clinicians realize that a patient’s lived environment can truly affect their obesity and/or obesity-related cancer status; being cognizant of that is the first step in holistic, comprehensive care,” he said. 

“One role that oncologists might be able to play in improving patients’ access to healthier food is to create and/or implement healthy lifestyle programs with gardening components to combat the poorest food environments that their patients likely reside in,” said Dr. Bevel. Clinicians also could consider the innovative approach of “food prescriptions” to help reduce the effects of deprived, built environments, he noted.

Looking ahead, next steps for research include determining the severity of association between food swamps and obesity-related cancer by varying factors such as cancer type, and examining any potential racial disparities between people living in these environments and obesity-related cancer, Dr. Bevel added.
 

Data provide foundation for multilevel interventions

The current study findings “raise a clarion call to elevate the discussion on food availability and access to ensure an equitable emphasis on both the importance of lifestyle factors and the upstream structural, economic, and environmental contexts that shape these behaviors at the individual level,” Karriem S. Watson, DHSc, MS, MPH, of the National Institutes of Health, Bethesda, Md., and Angela Odoms-Young, PhD, of Cornell University, Ithaca, N.Y., wrote in an accompanying editorial.

The findings provide a foundation for studies of obesity-related cancer outcomes that take the community environment into consideration, they added.

The causes of both obesity and cancer are complex, and the study findings suggest that the links between unhealthy food environments and obesity-related cancer may go beyond dietary consumption alone and extend to social and psychological factors, the editorialists noted.

“Whether dealing with the lack of access to healthy foods or an overabundance of unhealthy food, there is a critical need to develop additional research that explores the associations between obesity-related cancer mortality and food inequities,” they concluded.

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

Timing of a switch to treatment from gefitinib to osimertinib based on molecular progression led to an earlier switch than timing based on conventional measures in a new study of 100 adults with epidermal growth factor (EGFR)–mutant non–small cell lung cancer (NSCLC).

Previous studies have suggested that molecular progression of disease in patients with EGFR-mutant NSCLC, as measured by sequential plasma EGFR T790M, may precede radiological progression, as measured by Response Evaluation Criteria in Solid Tumors (RECIST).

However, the impact of these measures on timing of treatment changes and patient outcomes has not been examined, wrote Jordi Remon, MD, of Paris (France)–Saclay University and colleagues, in Annals of Oncology.

The European Organization for Research Treatment and Cancer Lung Cancer Group designed a phase 2 clinical trial known as APPLE to evaluate the use of sequential plasma EGFR T790M and determine the optimal sequencing for gefitinib and osimertinib in patients with EGFR-mutant NSCLC.

The researchers reported results from two randomized arms of the APPLE trial. In arm B, 52 patients received gefitinib until emergence of circulating tumor DNA (ctDNA) EGFR T790M mutation, based on the cobas EGFR test v2 (a real-time PCR test), or progression of disease based on Response Evaluation Criteria in Solid Tumors (RECIST). In arm C, 51 patients received gefitinib until disease progression based on RECIST. Both arms then switched to osimertinib. Patients randomized to a third arm (arm A) received osimertinib upfront until progression of disease based on RECIST, and they were not included in the current study.

The primary endpoint was progression-free survival (PFS) while receiving osimertinib at 18 months in patients who were originally randomized to gefitinib, then switched to osimertinib at the emergence of circulating tumor DNA. Secondary endpoints included PFS, overall response rate, overall survival, and brain PFS.

Patients entered the study between November 2017 and February 2020. A total of 75% and 65% of those in arms B and C, respectively, were female, approximately 65% had the mutation EGFR Del19, and approximately one-third had baseline brain metastases. In arm B, 17% of patients switched to osimertinib based on the emergence of ctDNA T790M mutation before progressive disease based on RECIST. The median time to molecular disease progression was 266 days.

More patients in arm B met the primary endpoint of PFS while receiving osimertinib at 18 months (67.2%) than in arm C (53.5%), after a median follow-up of 30 months.

As for secondary endpoints, the median PFS in the two arms was 22.0 months and 20.2 months, respectively. Median overall survival was 42.8 months in arm C and was not reached in arm B. The median brain PFS was 24.4 months for arm B and 21.4 months for arm C.

The benefits seen in the osimertinib patients may be due in part to the timing of the switch to correspond with molecular or radiological disease progression, the researchers wrote in their discussion.

In the future, more research is needed to determine whether molecular monitoring may impact patients’ outcomes, compared with monitoring based on radiological progression, they said.

The findings were limited by several factors, mainly the rapid evolution in the treatment landscape of EGFR-mutant NSCLC, the researchers noted.

Osimertinib is currently considered the preferred first-line treatment by most physicians, they said. “The APPLE trial is the first prospective study supporting the role of dynamic adaptive strategies based on ctDNA monitoring in patients with EGFR-mutant advanced NSCLC.”

Timing of a switch to treatment from gefitinib to osimertinib based on molecular progression led to an earlier switch than timing based on conventional measures in a new study of 100 adults with epidermal growth factor (EGFR)–mutant non–small cell lung cancer (NSCLC).

Previous studies have suggested that molecular progression of disease in patients with EGFR-mutant NSCLC, as measured by sequential plasma EGFR T790M, may precede radiological progression, as measured by Response Evaluation Criteria in Solid Tumors (RECIST).

However, the impact of these measures on timing of treatment changes and patient outcomes has not been examined, wrote Jordi Remon, MD, of Paris (France)–Saclay University and colleagues, in Annals of Oncology.

The European Organization for Research Treatment and Cancer Lung Cancer Group designed a phase 2 clinical trial known as APPLE to evaluate the use of sequential plasma EGFR T790M and determine the optimal sequencing for gefitinib and osimertinib in patients with EGFR-mutant NSCLC.

The researchers reported results from two randomized arms of the APPLE trial. In arm B, 52 patients received gefitinib until emergence of circulating tumor DNA (ctDNA) EGFR T790M mutation, based on the cobas EGFR test v2 (a real-time PCR test), or progression of disease based on Response Evaluation Criteria in Solid Tumors (RECIST). In arm C, 51 patients received gefitinib until disease progression based on RECIST. Both arms then switched to osimertinib. Patients randomized to a third arm (arm A) received osimertinib upfront until progression of disease based on RECIST, and they were not included in the current study.

The primary endpoint was progression-free survival (PFS) while receiving osimertinib at 18 months in patients who were originally randomized to gefitinib, then switched to osimertinib at the emergence of circulating tumor DNA. Secondary endpoints included PFS, overall response rate, overall survival, and brain PFS.

Patients entered the study between November 2017 and February 2020. A total of 75% and 65% of those in arms B and C, respectively, were female, approximately 65% had the mutation EGFR Del19, and approximately one-third had baseline brain metastases. In arm B, 17% of patients switched to osimertinib based on the emergence of ctDNA T790M mutation before progressive disease based on RECIST. The median time to molecular disease progression was 266 days.

More patients in arm B met the primary endpoint of PFS while receiving osimertinib at 18 months (67.2%) than in arm C (53.5%), after a median follow-up of 30 months.

As for secondary endpoints, the median PFS in the two arms was 22.0 months and 20.2 months, respectively. Median overall survival was 42.8 months in arm C and was not reached in arm B. The median brain PFS was 24.4 months for arm B and 21.4 months for arm C.

WASHINGTON – Six in 10 primary care pediatricians reported always screening adolescents for substance use, but less than half reported using a standardized instrument, Deepa Camenga, MD, said in a presentation at the 2023 Pediatric Academic Societies annual meeting.

Yale University

The American Academy of Pediatrics recommends universal screening for substance use in adolescents during annual health visits, but current screening rates and practices among primary care pediatricians in the United States are unknown, said Dr. Camenga, an associate professor at Yale University, New Haven, Conn.
 

Uniformity in screening is lacking

Dr. Camenga presented data from the 2021 AAP Periodic Survey, which included 1,683 nonretired AAP members in the United States. Residents were excluded. The current analysis included 471 pediatricians who reported providing health supervision to adolescents. Overall, 284 of the 471 included respondents (60%) reported always screening adolescent patients for substance use during a health supervision visit. Of these, 42% reported using a standardized screening instrument, Dr. Camenga said.

The majority (70%) of pediatricians who used a standardized screening tool opted for the CRAFFT tool (Car, Relax, Alone, Forget, Friends, Trouble) designed for ages 12-21 years. Another 21% reported using an unspecified screening tool, 4% used RAAPS (Rapid Assessment for Adolescent Preventive Services), 3% used S2BI (Screening to Brief Intervention), and 1% used BSTAD (Brief Screener for Tobacco, Alcohol, and other Drugs).

A total of 77% of respondents reported screening their adolescent patients for substance use without a parent or guardian present. Approximately half (52%) used paper-based screening, 22% used electronic screening, 21% used verbal screening, and 6% reported other methods.

A total of 68% and 70% of respondents, respectively, agreed or strongly agreed that top barriers to screening were the lack of an onsite provider for counseling and the lack of readily available treatment options. Other reported barriers included lack of knowledge or information, patient reluctance to discuss substance use, too many other priorities during the visit, and inadequate payment. Only 6% of respondents strongly agreed that lack of time was a barrier, said Dr. Camenga.

Screening frequency and screening practices varied by geographic region, Dr. Camenga said. Pediatricians in the South and Midwest were only half as likely as those in the Northeast to report always screening adolescents for substance use (adjusted odds ratio, 0.43 and 0.53, respectively; P < .05). Similarly, compared with pediatricians in the Northeast, those in the South, Midwest, and West were significantly less likely to report using a standardized instrument for substance use screening (aOR, 0.53, 0.24, and 0.52, respectively; P < 0.001 for all).

The disparities in screening by geographic region show that there is room for improvement in this area, said Dr. Camenga. Systems-level interventions such as treatment financing and access to telehealth services could improve primary care access to substance use treatment professionals, she said.

At the practice level, embedding screening and referral tools into electronic health records could potentially improve screening rates. Many primary care pediatricians do not receive training in identifying and assessing substance use in their patients, or in first-line treatment, Dr. Camenga said.

“We have to invest in a ‘train the trainer’ type of model,” she emphasized.
 

Data highlight regional resource gaps

The current study is important because it highlights potential missed opportunities to screen adolescents for substance use, said Sarah Yale, MD, assistant professor of pediatrics at the Medical College of Wisconsin, Milwaukee, in an interview. Dr. Yale said that the disparities in screening by region are interesting and should serve as a focus for resource investment because the lack of specialists for referral and treatment options in these areas is likely a contributing factor.

However, lack of training also plays a role, said Dr. Yale, who was not involved in the study but served as a moderator of the presentation session at the meeting. Many pediatricians in practice have not been trained in substance use screening, and the fact that many of those who did try to screen were not using a standardized screening tool indicates a need for provider education, she said. The take-home message for clinicians is to find ways to include substance use screening in the care of their adolescent patients. Additionally, more research is needed to assess how best to integrate screening tools into visits, whether on paper, electronically, or verbally, and to include training on substance use screening during pediatric medical training.

The survey was conducted by the American Academy of Pediatrics Research Division. This year’s survey was supported by the Conrad N. Hilton Foundation. Dr. Camenga had no financial conflicts to disclose. Dr. Yale had no financial conflicts to disclose.

Older women with high levels of physical activity showed twice the risk of atrial fibrillation (AFib) over 10 years as they did for cardiac disease or stroke, based on data from 46 cross-country skiers.

Although previous research suggests that women derive greater health benefits from endurance sports, compared with men, women are generally underrepresented in sports cardiology research, and most previous studies have focused on younger women, Marius Myrstad, MD, of Baerum Hospital, Gjettum, Norway, said in a presentation at the annual congress of the European Association of Preventive Cardiology.

Previous research also has shown an increased risk of AFib in male endurance athletes, but similar data on women are lacking, Dr. Myrstad said.

The researchers reviewed data from the Birkebeiner Ageing Study, a study of Norwegian cross-country skiers aged 65 years and older who were followed for 10 years. The participants were competitors in the 2009/2010 Birkebeiner race, a 54-km cross country ski race in Norway.

Participants responded to a questionnaire addressing cardiovascular disease risk factors, exercise habits, and other health issues. The mean age at baseline was 67.5 year. A total of 34 participants (76%) were available for follow-up visits in 2014, and 36 attended a follow-up visit in 2020. Cumulative exposure to exercise was 26 years.

A total of 86% of the women reported moderate to vigorous exercise in the past year at baseline; 61% did so at the 2020 follow-up visit. One of the participants died during the study period.

“The baseline prevalence of cardiovascular conditions was very low,” Dr. Myrstad noted.

However, despite a low prevalence of cardiovascular risk factors, the risk of AFib in the study population was twice as high as for other cardiac diseases and stroke (15.6%, 7.1%, and 7.1%, respectively).

The mechanism of action for the increased AFib remains unclear, but the current study highlights the need for large, prospective studies of female athletes to address not only AFib, but also exercise-induced cardiac remodeling and cardiovascular health in general, said Dr. Myrstad.

The findings were limited by the small sample size and use of self-reports, Dr. Myrstad said, and more research is needed to clarify the association between increased AFib and high-level athletic activity in women.

“We should strive to close the gap between female and male athletes in sports cardiology research,” he added.

Consider the big picture of AFib risk

This study is important because of the growing recognition that atrial fibrillation may be a preventable disease, said Gregory Marcus, MD, a cardiologist at the University of California, San Francisco, said in an interview.

American Heart Association

“Various behaviors or exposures that are under the control of the individual patient may reveal especially powerful means to help reduce risk,” he added.

Dr. Marcus said he was not surprised by the current study findings, as they reflect those of other studies suggesting a heightened risk for atrial fibrillation associated with very excessive exercise. However, the study was limited by the relatively small size and lack of a comparison group, he said. In addition, “The study was observational, and therefore the possibility that factors other than the predictor of interest, in this case intensive endurance exercise, were truly causal of atrial fibrillation could not be excluded,” he noted.

“It is very important to place this specialized analysis in the greater context of the full weight of evidence related to physical activity and atrial fibrillation,” said Dr. Marcus. “Specifically, when it comes to the general public and the great majority of patients we see in clinical practice, encouraging more physical activity is generally the best approach to reduce risks of atrial fibrillation,” he said. “It appears to be only in extraordinarily rigorous and prolonged endurance exercise that higher risks of atrial fibrillation may result,” he noted.

However, “Exercise also has many other benefits, related to overall cardiovascular health, brain health, bone health, and even cancer risk reduction, such that, even among the highly trained endurance athletes, the net benefit versus risk remains unknown,” he said. 

“While the risk of atrial fibrillation in these highly trained endurance athletes was higher than expected, it still occurred in the minority,” Dr. Marcus said. “Therefore, there are certainly other factors yet to be identified that influence this heightened atrial fibrillation risk, and future research aimed at elucidating these other factors may help identify individuals more or less prone to atrial fibrillation or other behaviors that can help mitigate that risk.”

Dr. Myrstad disclosed lecture fees from Bayer, Boehringer-Ingelheim, Bristol Myers Squibb, MSD, and Pfizer unrelated to the current study. Dr. Marcus disclosed serving as a consultant for Johnson and Johnson and InCarda, and holding equity as a cofounder of InCarda.

However, the study was limited by the relatively small size and lack of a comparison group, he said. In addition, “The study was observational, and therefore the possibility that factors other than the predictor of interest, in this case intensive endurance exercise, were truly causal of atrial fibrillation could not be excluded,” he noted.

“It is very important to place this specialized analysis in the greater context of the full weight of evidence related to physical activity and atrial fibrillation,” said Dr. Marcus. “Specifically, when it comes to the general public and the great majority of patients we see in clinical practice, encouraging more physical activity is generally the best approach to reduce risks of atrial fibrillation,” he said. “It appears to be only in extraordinarily rigorous and prolonged endurance exercise that higher risks of atrial fibrillation may result,” he noted.

However, “Exercise also has many other benefits, related to overall cardiovascular health, brain health, bone health, and even cancer risk reduction, such that, even among the highly trained endurance athletes, the net benefit versus risk remains unknown,” he said. 

“While the risk of atrial fibrillation in these highly trained endurance athletes was higher than expected, it still occurred in the minority,” Dr. Marcus said. “Therefore, there are certainly other factors yet to be identified that influence this heightened atrial fibrillation risk, and future research aimed at elucidating these other factors may help identify individuals more or less prone to atrial fibrillation or other behaviors that can help mitigate that risk.”

Dr. Myrstad disclosed lecture fees from Bayer, Boehringer-Ingelheim, Bristol Myers Squibb, MSD, and Pfizer unrelated to the current study. Dr. Marcus disclosed serving as a consultant for Johnson and Johnson and InCarda, and holding equity as a cofounder of InCarda.

Adults with cancer experienced significant reductions in pain after taking medicinal cannabis, in a study.

Physician-prescribed cannabis, particularly cannabinoids, has been shown to ease cancer-related pain in adult cancer patients, who often find inadequate pain relief from medications including opioids, Saro Aprikian, MSc, a medical student at the Royal College of Surgeons, Dublin, and colleagues, wrote in their paper.

However, real-world data on the safety and effectiveness of cannabis in the cancer population and the impact on use of other medications are lacking, the researchers said.

In the study, published in BMJ Supportive & Palliative Care, the researchers reviewed data from 358 adults with cancer who were part of a multicenter cannabis registry in Canada between May 2015 and October 2018.

The average age of the patients was 57.6 years, and 48% were men. The top three cancer diagnoses in the study population were genitorurinary, breast, and colorectal.

Pain was the most common reason for obtaining a medical cannabis prescription, cited by 72.4% of patients.

Data were collected at follow-up visits conducted every 3 months over 1 year. Pain was assessed via the Brief Pain Inventory (BPI) and revised Edmonton Symptom Assessment System (ESAS-r) questionnaires and compared to baseline values. Patients rated their pain intensity on a sliding scale of 0 (none) to 10 (worst possible). Pain relief was rated on a scale of 0% (none) to 100% (complete).

Compared to baseline scores, patients showed significant decreases at 3, 6 and 9 months for BPI worst pain (5.5 at baseline, 3.6 for 3, 6, and 9 months) average pain (4.1 at baseline, 2.4, 2.3, and 2.7 for 3, 6, and 9 months, respectively), overall pain severity (2.7 at baseline, 2.3, 2.3, and 2.4 at 3, 6, and 9 months, respectively), and pain interference with daily life (4.3 at baseline, 2.4, 2.2, and 2.4 at 3, 6, and 9 months, respectively; P less than .01 for all four pain measures).

“Pain severity as reported in the ESAS-r decreased significantly at 3-month, 6-month and 9-month follow-ups,” the researchers noted.

In addition, total medication burden based on the medication quantification scale (MQS) and morphine equivalent daily dose (MEDD) were recorded at 3, 6, 9, and 12 months. MQS scores decreased compared to baseline at 3, 6, 9, and 12 months in 10%, 23.5%, 26.2%, and 31.6% of patients, respectively. Also compared with baseline, 11.1%, 31.3%, and 14.3% of patients reported decreases in MEDD scores at 3, 6, and 9 months, respectively.

Overall, products with equal amounts of active ingredients tetrahydrocannabinol (THC) and cannabidiol (CBD) were more effective than were those with a predominance of either THC or CBD, the researchers wrote.

Medical cannabis was well-tolerated; a total of 15 moderate to severe side effects were reported by 11 patients, 13 of which were minor. The most common side effects were sleepiness and fatigue, and five patients discontinued their medical cannabis because of side effects. The two serious side effects reported during the study period – pneumonia and a cardiovascular event – were deemed unlikely related to the patients’ medicinal cannabis use.

The findings were limited by several factors, including the observational design, which prevented conclusions about causality, the researchers noted. Other limitations included the loss of many patients to follow-up and incomplete data on other prescription medications in many cases.

The results support the use of medical cannabis by cancer patients as an adjunct pain relief strategy and a way to potentially reduce the use of other medications such as opioids, the authors concluded.

The study was supported by the Canadian Consortium for the Investigation of Cannabinoids, Collège des Médecins du Québec, and the Canopy Growth Corporation. The researchers had no financial conflicts to disclose.
