Phytoestrogens show potential as a treatment for menopausal women with late-onset asthma that may relieve symptoms of both conditions, according to a new review.

Fluctuations in female sex steroid hormones during menstrual periods have been linked to asthma exacerbations, and the absence of these hormones during childhood and menopause has been associated with fewer and less severe asthma episodes, wrote Bettina Sommer, PhD, of the Instituto Nacional de Enfermedades Respiratorias, Mexico City, and colleagues.

Late-onset asthma (LOA) has been categorized as a specific asthmatic phenotype that includes menopausal women, and research is needed to explore therapeutic alternatives that might provide relief to older women suffering from LOA, they said.

In a review published in the International Journal of Molecular Sciences, the researchers outlined the potential of phytoestrogens to manage LOA as well as symptoms of menopause.

LOA is often nonatopic and distinguished by a lack of eosinophilic inflammation; it is also associated with obesity and pollutants such as cigarette smoke. LOA is more common in women versus men, and develops between ages 27 and 65 years, the researchers wrote. Very late-onset asthma, which develops in women aged 65 years and older, is related to low levels of total lack of circulating estrogens.

Previous studies have shown that hormone therapy reduces the risk of LOA in menopausal women, but concerns about side effects persist. Phytochemicals offer a low-risk alternative, but phytoestrogen-based hormone therapy and its role in LOA have not been well studied, the researchers wrote.

Estrogen receptors (ERs) have two intracellular isoforms, alpha and beta. “Notably, the literature sustains that ERs expression differs between asthmatics and nonasthmatics,” and mainly the beta ERs are up-regulated in asthma or during inflammations, the researchers said. Phytoestrogens activate ER and benefit postmenopausal women, especially those with asthma, in addition to their anti-inflammatory and antioxidant properties.

Studies using mouse models have shown that E2 phytoestrogen supplementation in mice both increases the expression of antioxidant enzymes and reduces inflammation, according to the researchers. Age-related changes in hormonal statues, immunology, and systemic inflammation may predispose older adults to more infections and asthma exacerbations, but also might drive the development of LOA.

As another example of potential connections between phytoestrogen and asthma, phytoestrogen’s action on an estrogen receptor, notably the beta-ER, was associated with lowered airway hyperresponsiveness in a mouse model, and beta-ER knockout mice showed reduced lung function, compared with wild-type and alpha-ER knockout mice.

More research is needed, but novel therapies using phytoestrogens offer an added advantage to older women with LOA by potentially easing some menopause symptoms with fewer side effects than other options, the researchers wrote. “They may also contribute to more efficient responses to infection and inflammation leading menopausal women to a much better quality of life.”

The study was funded by the Instituto Nacional de Enfermedades Respiratorias, Consejo Nacional de Ciencia y Tecnología, Programa de Apoyo a Proyectos de Investigación e Innovación Tecnológica, and the Universidad Nacional Autonoma de Mexico. The researchers had no financial conflicts to disclose.

Children with obstructive sleep apnea syndrome showed significantly reduced nasal ventilation function, compared with healthy controls, based on data from more than 200 individuals.

Previous research has shown an increased risk of obstructive sleep apnea syndrome (OSAS) in patients with compromised nasal respiration, but the association between increased nasal resistance (NR) and OSAS in children is controversial and remains unclear, wrote Ying Pang, MD, of Children’s Hospital of Chongqing Medical University, China, and colleagues.

In a study published in the Ear, Nose & Throat Journal, the researchers enrolled 109 children aged 6-12 years with OSAS and 116 healthy control children, with the goal of examining the role of nasal ventilation function on OSAS. Participants underwent acoustic rhinometry (AR) following polysomnography, and measurements of the nasal minimal cross-sectional area (NMCA) were taken in 3 segments, as were nasal cavity volume (NCV) from 0 cm to 5 cm, nasopharyngeal volume (NPV) from 6 cm to 8 cm, and distance of the minimal cross-sectional area to the nostril (DCAN). The children also underwent NR testing in both nostrils while awake and lying in a supine position.

Overall, the NR of children with OSAS were significantly higher than that of controls (P < .05). For AR, children with OSAS had significantly lower measures of NMCA, NCV, and NPV, but DCAN values were between the groups. Both AR and NR measures were similar among children with mild, moderate, or severe OSAS.

A subset of 90 children with mild or moderate OSAS were treated with intranasal corticosteroids (ICS) and oral montelukast for 12 weeks. Of these, 69 completed the study and were divided into three groups: effectively cured (group A), successfully treated (group B), and treatment failure (group C). The researchers compared the size of the tonsil adenoids, the polysomnography, NR, and AR before and after treatment and found significant differences in NR, NMCA, and NCV for the A and B groups but no significant changes in DCAN following treatment.

For group A, treatment was associated with a significant reduction in adenoid size and increase in NPV, but these changes did not occur in group B.

The findings were limited by several factors, including the small sample size and measurement of NR when patients were awake and sitting upright, and larger studies are needed to confirm the results, the researchers noted.

However, the results suggest that NVF plays a role in the pathogenesis of OSAS in children and suggest a need to improve NVF in treating these patients they concluded.

TOPLINE:

Strength training at any point in life is associated with a lower risk of knee pain and osteoarthritis, contrary to persistent assumptions of adverse effects.

METHODOLOGY:

• Researchers reviewed data on strength training and knee pain from 2,607 adults. They used the Historical Physical Activity Survey Instrument to assess the impact of strength training during four periods (ages 12-18 years, 19-34 years, 35-49 years, and 50 years and older).
• The participants were enrolled in the Osteoarthritis Initiative, a multicenter, prospective, longitudinal study; 44% were male, the average age was 64.3 years, and the mean body mass index was 28.5 kg/m².
• Strength training was defined as those exposed and not exposed, as well as divided into low, medium, and high tertiles for those exposed. A total of 818 individuals were exposed to strength training, and 1,789 were not exposed to strength training.
• The primary outcomes were frequent knee pain, radiographic OA (ROA), and symptomatic radiographic OA (SOA).

TAKEAWAY:

• The study is the first to examine the effect of strength training on knee health in a community population sample not selected for a history of elite weight lifting.
• Overall, strength training at any point in life was associated with lower incidence of frequent knee pain, ROA, and SOA, compared with no strength training (odds ratios, 0.82, 0.83, and 0.77, respectively).
• When separated by tertiles, only the high-exposure group had significantly reduced odds of frequent knee pain, ROA, and SOA, with odds ratios of 0.74, 0.70, and 0.69, respectively. A dose-response relationship appeared for all three conditions, with the lowest odds ratios in the highest strength training exposure groups.
• Findings were similar for different age ranges, but the association between strength training and less frequent knee pain, less ROA, and less SOA was strongest in the older age groups.

IN PRACTICE:

“Our findings support the idea that the medical community should proactively encourage more people to participate in strength training to help reduce their risk of osteoarthritis and other chronic conditions,” the researchers write.

SOURCE:

The study, with first author Grace H. Lo, MD, of Baylor College of Medicine, Houston, and colleagues, was published in Arthritis and Rheumatology.

LIMITATIONS:

The observational design and self-selected study population of strength training participants might bias the results, including participants’ recall of their activity level levels and changes in exercise trends over time. More research is needed to explore associations between strength training and knee OA among those who started strength training at a younger age.

DISCLOSURES:

The study was funded in part by the VA Health Services Research and Development Center for Innovations in Quality, Effectiveness, and Safety at the Michael E. DeBakey VA Medical Center, Houston, and by donations to the Tupper Research Fund at Tufts Medical Center. The Osteoarthritis Initiative is supported by the National Institutes of Health; private funding partners include Merck Research Laboratories, Novartis, GlaxoSmithKline, and Pfizer. Three authors report having financial relationships with multiple pharmaceutical companies.

WASHINGTON – Online vendors of nicotine toothpicks rarely verify the age of purchasers, whereas brick-and-mortar stores are more likely to ask for ID, according to a study of 77 stores and 16 online sites.

Online nicotine toothpick sales are “the Wild West” in terms of regulation, said Abhijeet Grewal, a research assistant at Cohen Children’s Medical Center, in New Hyde Park, N.Y., who presented the findings at the annual meeting of the American Academy of Pediatrics.

Nicotine toothpicks have become popular among teenagers as a relatively inconspicuous way to access the drug, Mr. Grewal said. The nicotine content of the toothpicks varies, but many contain as much as 2-3 mg per pick compared with the 1.1-1.8–mg amount inhaled per the average cigarette, he said. The cheap price and teen-friendly flavors like cherry and mocha add to the appeal of the picks. However, data on the marketplace and accessibility of these products are lacking, Mr. Grewal said.

To find out how easily youth can buy nicotine toothpicks through in-person and online channels, Mr. Grewal and colleagues identified and called 404 brick-and-mortar retailers across the United States by phone and asked whether they required ID for purchase of nicotine toothpicks; of the 77 locations that responded, only 1 said that they would sell nicotine toothpicks without asking for proof of age.

The researchers also collected data on 16 vendor websites that sold nicotine toothpicks with shipment to the United States (identified from pixotine.com).

Overall, 11 sites (69%) prompted users to confirm that they were aged 21 years or older to either view the site or place orders, but 12 sites (75%) required no formal method of verification.

Warnings or disclaimers, such as “nicotine is an addictive chemical,” appeared on 69% of sites. Marketing statements including terms such as “discreet” and “cost-effective” to describe the toothpicks, Mr. Grewal said, and online reviews endorsed the products as “convenient” and “rich in flavor.”

The sites in the study offered a total of 32 different flavors, Mr. Grewal said, and 44% of the sites offered some type of discount on prices, which land in the range of approximately $5 for a tube of 20 toothpicks.

Nicotine toothpicks and flavored toothpicks without nicotine were originally marketed as smoking cessation aids, said Mr. Grewal, but their low price point and ability to be consumed discreetly makes them appealing to teens for nicotine use in many environments.

More research is needed to characterize youth use of nicotine toothpick products, as well as purchasing patterns, he said. However, the results highlight the need for regulation of nicotine toothpick vendors to protect youth from accessing nicotine in this form, he said.
 

Ask adolescents about toothpicks

“While nicotine replacement therapy [NRT] products may be an effective way for people to quit smoking, these products have the potential to introduce minors to nicotine in a seemingly innocent way resulting in dependence,” senior author Ruth Milanaik, DO, also of Cohen Children’s Medical Center, said in an interview. “Many children are intrigued by these fun flavored products, and our team was interested in examining the availability of these products to minors.”

Overall, “our team was quite pleased with brick-and-mortar stores’ spoken requirements of age verification for purchase, and quite worried about the availability of nic picks through online vendors,” she continued.

Clinicians, educators, and parents should be aware of the existence of nicotine toothpicks and the ease with which minors can attain them through online vendors, Dr. Milanaik said. “While NRT is a part of smoking cessation programs, nicotine toothpicks should not be used by minors without clinical reasons,” she said. “The innocuous and innocent nature of these toothpicks may entice minors to try and regularly use these without regard to future dependence.”

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

To find out how easily youth can buy nicotine toothpicks through in-person and online channels, Mr. Grewal and colleagues identified and called 404 brick-and-mortar retailers across the United States by phone and asked whether they required ID for purchase of nicotine toothpicks; of the 77 locations that responded, only 1 said that they would sell nicotine toothpicks without asking for proof of age.

The researchers also collected data on 16 vendor websites that sold nicotine toothpicks with shipment to the United States (identified from pixotine.com).

Overall, 11 sites (69%) prompted users to confirm that they were aged 21 years or older to either view the site or place orders, but 12 sites (75%) required no formal method of verification.

Warnings or disclaimers, such as “nicotine is an addictive chemical,” appeared on 69% of sites. Marketing statements including terms such as “discreet” and “cost-effective” to describe the toothpicks, Mr. Grewal said, and online reviews endorsed the products as “convenient” and “rich in flavor.”

The sites in the study offered a total of 32 different flavors, Mr. Grewal said, and 44% of the sites offered some type of discount on prices, which land in the range of approximately $5 for a tube of 20 toothpicks.

Nicotine toothpicks and flavored toothpicks without nicotine were originally marketed as smoking cessation aids, said Mr. Grewal, but their low price point and ability to be consumed discreetly makes them appealing to teens for nicotine use in many environments.

More research is needed to characterize youth use of nicotine toothpick products, as well as purchasing patterns, he said. However, the results highlight the need for regulation of nicotine toothpick vendors to protect youth from accessing nicotine in this form, he said.
 

Ask adolescents about toothpicks

“While nicotine replacement therapy [NRT] products may be an effective way for people to quit smoking, these products have the potential to introduce minors to nicotine in a seemingly innocent way resulting in dependence,” senior author Ruth Milanaik, DO, also of Cohen Children’s Medical Center, said in an interview. “Many children are intrigued by these fun flavored products, and our team was interested in examining the availability of these products to minors.”

Overall, “our team was quite pleased with brick-and-mortar stores’ spoken requirements of age verification for purchase, and quite worried about the availability of nic picks through online vendors,” she continued.

Clinicians, educators, and parents should be aware of the existence of nicotine toothpicks and the ease with which minors can attain them through online vendors, Dr. Milanaik said. “While NRT is a part of smoking cessation programs, nicotine toothpicks should not be used by minors without clinical reasons,” she said. “The innocuous and innocent nature of these toothpicks may entice minors to try and regularly use these without regard to future dependence.”

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

Endoscopic sinus surgery (ESS) has no significant impact on asthma symptoms for patients with chronic rhinosinusitis up to a year after the procedure, a study of 64 patients shows.

Although ESS is effective in relieving chronic rhinosinusitis, whether it leads to improvement of asthma severity for patients with both conditions remains unclear, Anyull Dayanna Bohórquez Caballero said in a presentation at the American Academy of Otolaryngology–Head and Neck Surgery (AAO-HNS) 2023 annual meeting.

The study “offers a unique approach to explore the effects of endoscopic sinus surgery in a real-world context, with valuable insights that differ from previous research,” Dr. Bohórquez Caballero, an international medical graduate and research fellow of the Mayo Clinic, Jacksonville, Fla., said in an interview.

Under the leadership of senior author Angela Donaldson, MD, Dr. Bohórquez Caballero and colleagues at the Mayo Clinic in Jacksonville analyzed data from 185 adults with both asthma and chronic rhinosinusitis who underwent ESS at the clinic between 2013 and 2023. Asthma severity was evaluated up to 3 months before and 1 year after surgery. Patients’ asthma severity was classified as mild, moderate, or severe on the basis of current Global Initiative for Asthma guidelines using medication requirements.

The final study population included 64 patients; 42 of these (66.7%) had chronic rhinosinusitis with nasal polyps. Outcomes included differences in asthma severity, asthma medication doses, and the number of medications.

Overall, there was no significant difference in measures of mild, moderate, or severe asthma before and after ESS in a McNemar paired test (P values: .130, .999, and .288, respectively). Similarly, no difference was found before and after ESS in terms of total inhaled corticosteroid dose (P = .999), number of medications prescribed (P = .157), or control of the disease (P = .078).

The findings were limited by the relatively small number of patients. The study is the first known to assess the real-world impact of ESS on asthma severity, said Bohórquez Caballero.
 

Expected reduction in asthma severity not seen

Past studies have suggested that ESS improves parameters such as pulmonary function test results or sinonasal outcomes, Dr. Bohórquez Caballero told this news organization. “Our findings indicate that ESS does not significantly impact asthma severity or trends in treatment, including the number and/or dose of medications, in everyday practice.

Our study also identified crucial opportunities to reinforce interdisciplinary follow-up after ESS,” she noted, and it provides a comprehensive depiction of the outcomes experienced by patients with chronic rhinosinusitis and asthma who undergo ESS.

“We were expecting a reduction in severity or a decrease in the dose of inhaled corticosteroid therapies, and we expected to see a translation from previous evidence into clinical practice; however, we did not,” said Dr. Bohórquez Caballero.

“The take-home message is that while there is a strong correlation between CRS and asthma, it does not appear that ESS alone improves real-world treatment based on asthma severity,” she said. “However, our findings have shown that patients may experience a longer period without the need for a reliever medication in the early postoperative period.”

Looking ahead, “We want to explore what happens 5 or 6 months after sinus surgery that would explain the sudden need for a reliever medication,” she added. “Future studies are warranted to investigate the long-term effects of ESS on asthma severity as it relates to modifications of asthma regimens.”
 

Data important for patient discussions

The current study is important because of the frequency of comorbid asthma among patients with chronic rhinosinusitis, Megan Durr, MD, of the University of California, San Francisco, said in an interview.

“When we are considering functional endoscopy sinus surgery with patients, we are often asked if the surgery will impact the severity of their asthma symptoms,” said Dr. Durr, who served as a moderator for the session in which the study was presented.

“I am surprised the study did not see any difference in asthma severity after sinus surgery, as we often talk to patients about the unified airway that refers to the shared epidemiologic and pathophysiologic relationship between the upper and lower airways,” she told this news organization.

“This study will allow us to have a more informed evidenced-based discussion with patients and their primary care providers and/or pulmonologists” about what to expect for asthma outcomes following surgery, she said.

The study received no outside funding. Dr. Durr has disclosed no relevant financial relationships.

WASHINGTON – Get the back story before rushing to diagnose a seizure disorder in a child, Michael Strunc, MD, said in a presentation at the annual meeting of the American Academy of Pediatrics.

Clinicians should ask parents or caregivers about the child’s behavior before the suspected seizure, whether there were any triggers, and if so, what might they have been, according to Dr. Strunc, a child neurologist and sleep medicine specialist at Children’s Hospital of the King’s Daughters, Norfolk, Va.

“Most seizures don’t have triggers,” he said. Rather, patients often become stiff, experience a motor event that builds in intensity then slows and stops, and finally, the patient is sleepy and tired. Clinicians should also find out whether the event had a beginning, middle, and end.

Approximately 0.6% of children younger than 17 years in the United States have active epilepsy, according to the Centers for Disease Control and Prevention.

Dr. Strunc offered a few more tips for diagnosing a child:

• Ask whether the patient’s eyes were open during the event. If the eyes were closed or squished closed, “it is almost never a seizure,” he said.
• Find out whether the patient was awake or asleep, and how, if at all, caregivers attempted to stop the event.
• Ask if the child’s experiences were repeating and predictable, and inquire about a family history of seizures or other events.
• Inquire about any developmental changes and other changes in the child, such as irritability, regression, or ataxia.

The differential diagnosis for a seizure includes nonepileptic events that occur with and without changes in consciousness or sleep. These events range from breath-holding and hyperventilation to night terrors, narcolepsy, migraine, and attention-deficit/hyperactivity disorder, he said.
 

Is it epilepsy?

Dr. Strunc shared several cases of neurologic “events” ranging from simple to severe.

In one case, a 10-month-old infant girl with a potential tonic/staring seizure presented with a history of events that involved getting stuck in a stiff position, usually while sitting in a car seat or highchair, with adducting of legs, redness of face, and “zoned-out” expression. The infant was healthy, smart, and precocious, with no illness, fever, or trauma, but the mother was very concerned, Dr. Strunc said.

The diagnosis: Self-gratification, which is benign and usually outgrown, although it can become extreme, he said.

By contrast, “absence,” also known as idiopathic generalized epilepsy, presents as brief events of 4-10 seconds that may occur up to hundreds of times a day. This type of epilepsy is associated with the sudden onset of impaired consciousness and unresponsiveness. These events end abruptly, and the child may be unaware. Absence is more common in girls. It usually occurs after age 4 and usually remits by about age 12, Dr. Strunc said.

However, the onset of absence in patients younger than age 3 is associated with increased odds of neurodevelopmental abnormalities “and probably represents another epilepsy syndrome,” he said.

Absence symptoms may mirror those of children who are simply daydreamers, Dr. Strunc noted. One way to confirm absence is by provoking hyperventilation, which will bring on an episode of absence if present, he said. EEGs provide evidence as well.

Acute ataxia in children has a wide differential that sends kids and families to the pediatrician or emergency department, Dr. Strunc said. Acute cerebellar ataxia is characterized by abrupt and symmetric symptoms, with no mental status changes, no fever, no meningitis, and no headache. A wide, unstable gait is a distinguishing feature, Dr. Strunc said.

However, other causes of acute ataxia should be ruled out, including toxic ingestion, tick paralysis, central nervous system infections, vascular conditions, and genetic conditions.
 

Don’t miss those ticks

Especially during periods when kids are outdoors, clinicians should consider a tick bite as a source of ataxia and neurologic symptoms in children, Dr. Strunc emphasized. Tick paralysis notably resembles many symptoms of Guillain-Barré syndrome (acute inflammatory demyelinating polyneuropathy).

Dr. Strunc described a case involving a 5-year-old girl who developed sudden problems with gait. The problems worsened quickly and prompted an emergency department visit.

The girl had an unremarkable history, she had not experienced mental status changes, her strength was normal, and she had just returned from a Girl Scouts trip. The patient was presumed to have Guillain-Barré. IVIG was initiated when an emergency nurse found a tick on her scalp. The tick was removed, and the patient left the hospital within 24 hours.

Children with tick paralysis are usually symptomatic after 5-7 days with the tick attached, Dr. Strunc said. They recover within a day after tick removal.

Overall, actual seizures are less common than other neurologic events in children, according to Dr. Strunc. Details on history, lack or presence of neurologic feature, and normal child development can help guide evaluation.

Take advantage of videos, he emphasized, as many parents and caregivers record a child’s neurologic events.

“Ataxia is scary, but exam and associated findings will help you with etiology,” he said.

Dr. Strunc has received research support from Jazz and Harmony and has served on the speakers’ bureau for Jazz Pharmaceuticals, Harmony Biosciences, and Avadel, unrelated to his presentation.

The Food and Drug Administration has approved a topical combination of 1.2% clindamycin phosphate, 0.15% adapalene, and 3.1% benzoyl peroxide for the treatment of acne vulgaris in patients aged 12 years and older, according to a press release from the manufacturer.

The combination of an antibiotic, a retinoid, and an antibacterial in a gel formulation will be marketed as Cabtreo, and is expected to be available in the first quarter of 2024, according to Ortho Dermatologics.

The treatment was evaluated in a pair of phase 3 multicenter, randomized, controlled trials of 363 patients with moderate to severe acne, according to the company. Approximately 50% of patients across both studies met the primary endpoint of treatment success after 12 weeks of daily use, compared with 24.9% and 20.4% of placebo patients on vehicle in studies 1 and 2, respectively. Treatment success in both studies was defined as a reduction of at least two grades from baseline on the Evaluator’s Global Severity Score (EGSS) with scores of clear (0) or almost clear (1), and absolute change from baseline in both inflammatory and noninflammatory lesions. Patients were evaluated at 2, 4, 8, and 12 weeks.

Patients in the treatment groups for both studies had significantly greater absolute mean reductions in both inflammatory and noninflammatory lesions from baseline to week 12, compared with those in the vehicle group. The mean reductions with the treatment vs. vehicle were 75.7% vs. 59.6% and 72.7% vs. 47.6% for inflammatory and noninflammatory lesions, respectively, in study 1, and 80.1% vs. 56.2% and 73.3% vs. 49.0% for inflammatory and noninflammatory lesions, respectively, in study 2.

The most common adverse events were erythema, application-site reactions, pain, irritation, exfoliation, and dermatitis, all of which were more common in the treatment groups vs. the placebo groups.

Approximately 50% of patients across both studies met the primary endpoint of treatment success after 12 weeks of daily use, compared with 24.9% and 20.4% of placebo patients on vehicle in studies 1 and 2, respectively. Treatment success in both studies was defined as a reduction of at least two grades from baseline on the Evaluator’s Global Severity Score (EGSS) with scores of clear (0) or almost clear (1), and absolute change from baseline in both inflammatory and noninflammatory lesions. Patients were evaluated at 2, 4, 8, and 12 weeks.

Patients in the treatment groups for both studies had significantly greater absolute mean reductions in both inflammatory and noninflammatory lesions from baseline to week 12, compared with those in the vehicle group. The mean reductions with the treatment vs. vehicle were 75.7% vs. 59.6% and 72.7% vs. 47.6% for inflammatory and noninflammatory lesions, respectively, in study 1, and 80.1% vs. 56.2% and 73.3% vs. 49.0% for inflammatory and noninflammatory lesions, respectively, in study 2.

The most common adverse events were erythema, application-site reactions, pain, irritation, exfoliation, and dermatitis, all of which were more common in the treatment groups vs. the placebo groups.

The Food and Drug Administration has approved a topical combination of 1.2% clindamycin phosphate, 0.15% adapalene, and 3.1% benzoyl peroxide for the treatment of acne vulgaris in patients aged 12 years and older, according to a press release from the manufacturer.

Just over half of endoscopists use cold snare polypectomy to remove small polyps of less than 1 cm, despite recommendations from the U.S. Multisociety Task Force for its use in small lesions, shows new research presented this week in Vancouver at the annual meeting of the American College of Gastroenterology.

Polypectomy is a key part of colorectal cancer prevention, but endoscopists’ choice of polypectomy is a major factor in quality, and the characteristics of polypectomies in clinical practice are highly variable, said Seth D. Crockett, MD, of Oregon Health & Science University, Portland, in a presentation at the meeting.

Cold snare polypectomy is preferred for the removal of polyps less than 1 cm because of a high complete resection rate and a strong safety profile, compared to forceps and hot snares, which tend to be associated with high incomplete resection rates, inadequate histopathologic specimens, and/or complication rates. The adherence of endoscopists to the recommendations was not known until now, Dr. Crockett said.

This was a cross-sectional study of 1,589,499 colonoscopies that were conducted between 2019 and 2022 in patients (aged 40-80 years) who underwent a screening or surveillance colonoscopy in which at least one small polyp of less than 1 cm was removed. The final analysis included 3,082 endoscopists. Colonoscopies in which larger polyps were detected, or there was a confirmed case of cancer, were not included.

The mean endoscopist cold snare polypectomy rate (CSPR) was 51.2%, which was “lower than expected based on current guideline recommendations,” Dr. Crockett said.

Higher cold snare polypectomy rates were more common among specialists with training in gastroenterology, and more common among those who practiced in the Midwest (69%), as compared with practitioners in the Northeast who, at 40%, had the lowest rate. Colonoscopy volume, adenoma detection rate (ADR), serrated polyp detection rate (SDR), and cecal intubation rate (CIR), were all associated with a higher CSPR.

CSPR was more than 30% higher for endoscopists with an adenoma detection rate (ADR) of greater than 35%, compared with those with an ADR of less than 25% (58% vs. 27%, respectively; P < .0001). Lower usage rates among endoscopists with low ADRs could compound the problem of interval cancer if polyps are missed, Dr. Crockett said. Endoscopist serrated polyp detection rates of 7% of higher, cecal intubation rates of 95% or higher, and mean withdrawal times greater than 9 minutes were significantly associated with higher CSPR (P < .0001 for all).

The findings suggest a correlation between higher cold snare usage and improved quality metrics, such as adenoma detection rate and cecal intubation rate, said Jonathan A. Leighton, MD, of the Mayo Clinic, Scottsdale, Ariz., in an interview.

“I would agree with the authors that much of the focus on colonoscopy quality has been directed toward polyp detection, and little on the quality of polyp resection, which can be difficult to measure,” he said. “Their results suggest that cold snare polypectomy for removal of small polyps is currently underutilized, but as with any polypectomy, it is important that all of the dysplastic tissue is removed using good technique.”

The results were strengthened by the large sample size and high fidelity of measurements of polyp size, polypectomy tools, and quality measures. But more research is needed to determine the impact of polypectomy technique on outcomes of colonoscopy efficacy and safety. In terms of limitations, small polyps carry a relatively low risk of recurrence, and the associations between an endoscopist’s polypectomy practice and polyp recurrence, interval cancer, and adverse events were not examined, Dr. Crockett said.

The study was supported by a grant from the ACG. Dr. Crockett disclosed relationships with Carelon, Exact Sciences, Freenome, and Guardant.

Approximately 1 in 40 women are carriers of single gene disorders that could manifest as pregnancy complications, based on data from more than 90,000 individuals.

Single gene disorders remain a leading cause of morbidity and mortality in newborns and children, but carrier screening for such disorders was limited until recent advances in DNA sequencing, wrote Vivienne Souter, MD, of Natera in Austin, Tex., and colleagues.

Identifying single gene disorders in carrier screening also includes the discovery of genetic variants that could affect the carrier parent during pregnancy, they said.

In a study published in Obstetrics and Gynecology, the researchers reviewed data from 91,637 female patients who underwent testing via a 274-gene carrier screening panel. The median age of the participants was 32.8 years, and approximately half were pregnant at the time of the testing.

Based on previously published reports, the researchers identified 12 genes with potential for carrier manifestations during pregnancy; of these, 9 had manifestations whether or not the fetus was affected by the genetic condition (ABCB11, COL4A3, COL4A4, COL4A5, DMD, F9, F11, GLA, and OTC) and 3 had manifestations only if the fetus was affected by the condition (CPT1A, CYP19A1, and HADHA).

Overall, 66% of the tests were positive for at least one of the 274 genes; the frequency of potentially pathogenic variants for the 12 genes that could manifest as complications during pregnancy ranged from 1 in 117 individuals for the F11 gene to 1 in 8,331 for the OTC gene.

A total of 2.3% of the participant tests were associated a pathogenic or likely pathogenic variant in at least 1 of the 12 genes, which accounted for 3.5% of all positive samples, and 2.0% were identified as carriers for 1 of the 9 genes that could affect women during pregnancy regardless of fetal genetic status.

“People of Ashkenazi Jewish heritage were over-represented in the carrier group, representing 6.0% of carriers but only 1.9% of the entire study cohort,” the researchers noted.

Manifestations related to the 12 genes included cardiomyopathy, hemorrhage, gestational hypertensive disorders, cholestasis of pregnancy, acute fatty liver, hyperammonemic crisis, and maternal virilization.

“The reported incidence of pregnancy complications in carriers ranged from 10% to 62% depending on the gene involved, but information was limited for most of the conditions,” and published literature identified management recommendations for 11 of the 12 genes, the researchers wrote.

The findings were limited by several factors including the use of cases received by the laboratory, which might have yielded more women with above-average risk because of family history, the researchers noted. Other limitations included a lack of data on further evaluation or counseling after the screening, and the lack of separation of the results according to the specific variant, they said. Also, the study population was limited to those who had access to carrier screening, and may not be generalizable to the population at large.

However, the results support the value of carrier screening, and pretest counseling should inform individuals of the potential identification of genes that might increase their risk of complications during pregnancy, the researchers said.

“Obstetric care professionals should also be aware that carrier status for certain conditions can be important for risk assessment and management in pregnancy,” and post-test genetic counseling, follow-up testing, and clinical management can help reduce risks, which could potentially be identified prior to pregnancy, they concluded.

WASHINGTON – The nation’s largest group of pediatricians is advising parents to recognize the limits of “toddler milk,” formula products purporting to be beneficial for young children. These products are not nutritionally complete and are not to be confused with formulas for infants younger than 12 months.

“Toddler drinks do not offer anything nutritionally exceptional,” said George J. Fuchs III, MD, a pediatric gastroenterologist at the University of Kentucky, Lexington, who presented a clinical report on toddler formulas from the American Academy of Pediatrics at the group’s annual meeting. The products are not regulated by the U.S. Food and Drug Administration and should not be given to infants younger than 12 months in place of infant formulas, but murky marketing can leave parents and caregivers confused as to whether these products are essential for good health, Dr. Fuchs said.

Despite the rise in marketing of formulas pitched as toddler milks, growth milks, or transition formulas, among other names, the AAP says these formulas are both unregulated and unnecessary for the vast majority of toddlers because they have adequate diets and do not require supplementation.

Clinicians should understand and explain the distinction between products formulated for infants younger than 12 months and those designed for children aged 12 months or older, Dr. Fuchs added.

Formulas for infants younger than 12 months represent a distinct product category for the FDA and are required to be nutritionally complete for this age, Dr. Fuchs said. Infant formulas sold in the United States must meet nutrition requirements as defined by the Infant Formula Act of 1980 (updated in 1986), and the facilities that manufacture them are regularly inspected by the agency.

In contrast, toddler formulas are not regulated or categorized by the FDA and therefore may vary widely in composition and are not nutritionally complete for any age, he said.

One area of concern is that parents or caregivers misunderstand and give these products to infants younger than 12 months instead of infant formulas, he said.

Also, mass-market toddler formulas are inadequate for children with disease-specific requirements, such as malnutrition, gastrointestinal disorders, metabolic disorders, or food allergies.
 

Questionable composition, misleading marketing

Toddler formulas are not only unnecessary but could be detrimental to children’s health, Dr. Fuchs said. Some formulas have high sodium content relative to cow’s milk or may be high or low in protein. Other products have added sweeteners, which could contribute to an increased preference for sweetened foods as the children get older, he noted.

However, manufacturers of regulated infant products often market them alongside their infant formula, which can be confusing for parents and caregivers. The products often have similar names, images, slogans, and logos, and may suggest benefits such as immune system support, brain development, and digestive health, he added.

A 2020 survey published in Maternal and Child Nutrition found that 60% of approximately 1,000 caregivers of children aged 12-36 months agreed with the marketing claim that toddler formulas or powdered milks provide nutrition that is not available from other food and drinks, Dr. Fuchs said.
 

Balanced diet is best for healthy children

For infants younger than 12 months, the AAP recommends that the liquid portion of the diet should come from human milk or a standard infant formula that has been reviewed by the FDA based on the Infant Formula Act, Dr. Fuchs said.

Children aged 12 months or older should receive a varied diet with fortified foods. Formula can safely be used as part of a varied diet; however, it offers no nutritional advantage for most children over a well-balanced diet that includes human milk and/or cow milk, “and should not be promoted as such,” Dr. Fuchs noted.

“The category of these toddler drinks has grown and the landscape has changed quite a bit; we thought it was appropriate that we review this category,” Dr. Fuchs said in an interview.

Dr. Fuchs advised pediatricians in practice to follow the AAP’s guidance for breastfeeding infants if possible and progression to formula as needed for infants up to age 1 year, followed by transition to cow milk (or alternatives for those with cow milk allergies) and the addition of a healthy mixed diet.
 

Formula choices pose practice challenges

In an interview, Cathy Haut, DNP, CPNP-AC, CPNP-PC, a pediatric nurse practitioner in Rehoboth Beach, Del., pointed out that not only are parents often baffled by formula choices, but many are also hesitant to make a switch to regular milk as children get older because they worry that cow’s milk is inadequate for nutrition or is not as “clean” or “sterile” as formula.

In some cases, parents may have had difficulty in acquiring genuine infant formulas, which were relocated to locked cabinets in stores during recent shortages and began using toddler formulas as an alternative for infants younger than 1 year, she added.

“If breastfeeding is not possible, using approved infant formula is preferred, switching to whole cow milk at 1 year of age,” she said. “Nutritional assessment is an important part of well-child visits, with caregiver counseling regarding importance of intake of variety of fortified foods [that] offer vitamins, calcium, iron and zinc,” Ms. Haut added. Although toddler formulas are safe additions to the diets of most young children older than 1 year, supplementation of specific nutrients such as vitamin D if needed is a more effective option, she said.

“National health studies indicate that U.S. toddlers have nutritional gaps in their diet often related to picky eating,” an Abbott spokesperson said in an interview. “When [toddlers] don’t do well transitioning to table foods or won’t drink milk, our toddler drinks contain many of the complementary nutrients, such as vitamins and minerals, that they may be missing in their diet. Toddler drinks may be an option to help fill nutrient gaps for these children 12-36 months of age. Abbott does not recommend or indicate its toddler drinks for infants under 12 months of age,” according to the company.

Dr. Fuchs had no financial conflicts to disclose. Dr. Haut had no financial conflicts to disclose.

“The category of these toddler drinks has grown and the landscape has changed quite a bit; we thought it was appropriate that we review this category,” Dr. Fuchs said in an interview.

Dr. Fuchs advised pediatricians in practice to follow the AAP’s guidance for breastfeeding infants if possible and progression to formula as needed for infants up to age 1 year, followed by transition to cow milk (or alternatives for those with cow milk allergies) and the addition of a healthy mixed diet.
 

Formula choices pose practice challenges

In an interview, Cathy Haut, DNP, CPNP-AC, CPNP-PC, a pediatric nurse practitioner in Rehoboth Beach, Del., pointed out that not only are parents often baffled by formula choices, but many are also hesitant to make a switch to regular milk as children get older because they worry that cow’s milk is inadequate for nutrition or is not as “clean” or “sterile” as formula.

In some cases, parents may have had difficulty in acquiring genuine infant formulas, which were relocated to locked cabinets in stores during recent shortages and began using toddler formulas as an alternative for infants younger than 1 year, she added.

“If breastfeeding is not possible, using approved infant formula is preferred, switching to whole cow milk at 1 year of age,” she said. “Nutritional assessment is an important part of well-child visits, with caregiver counseling regarding importance of intake of variety of fortified foods [that] offer vitamins, calcium, iron and zinc,” Ms. Haut added. Although toddler formulas are safe additions to the diets of most young children older than 1 year, supplementation of specific nutrients such as vitamin D if needed is a more effective option, she said.

“National health studies indicate that U.S. toddlers have nutritional gaps in their diet often related to picky eating,” an Abbott spokesperson said in an interview. “When [toddlers] don’t do well transitioning to table foods or won’t drink milk, our toddler drinks contain many of the complementary nutrients, such as vitamins and minerals, that they may be missing in their diet. Toddler drinks may be an option to help fill nutrient gaps for these children 12-36 months of age. Abbott does not recommend or indicate its toddler drinks for infants under 12 months of age,” according to the company.

WASHINGTON – The nation’s largest group of pediatricians is advising parents to recognize the limits of “toddler milk,” formula products purporting to be beneficial for young children. These products are not nutritionally complete and are not to be confused with formulas for infants younger than 12 months.

“Toddler drinks do not offer anything nutritionally exceptional,” said George J. Fuchs III, MD, a pediatric gastroenterologist at the University of Kentucky, Lexington, who presented a clinical report on toddler formulas from the American Academy of Pediatrics at the group’s annual meeting. The products are not regulated by the U.S. Food and Drug Administration and should not be given to infants younger than 12 months in place of infant formulas, but murky marketing can leave parents and caregivers confused as to whether these products are essential for good health, Dr. Fuchs said.

Despite the rise in marketing of formulas pitched as toddler milks, growth milks, or transition formulas, among other names, the AAP says these formulas are both unregulated and unnecessary for the vast majority of toddlers because they have adequate diets and do not require supplementation.

Clinicians should understand and explain the distinction between products formulated for infants younger than 12 months and those designed for children aged 12 months or older, Dr. Fuchs added.

Formulas for infants younger than 12 months represent a distinct product category for the FDA and are required to be nutritionally complete for this age, Dr. Fuchs said. Infant formulas sold in the United States must meet nutrition requirements as defined by the Infant Formula Act of 1980 (updated in 1986), and the facilities that manufacture them are regularly inspected by the agency.

In contrast, toddler formulas are not regulated or categorized by the FDA and therefore may vary widely in composition and are not nutritionally complete for any age, he said.

One area of concern is that parents or caregivers misunderstand and give these products to infants younger than 12 months instead of infant formulas, he said.

Also, mass-market toddler formulas are inadequate for children with disease-specific requirements, such as malnutrition, gastrointestinal disorders, metabolic disorders, or food allergies.
 

Questionable composition, misleading marketing

Toddler formulas are not only unnecessary but could be detrimental to children’s health, Dr. Fuchs said. Some formulas have high sodium content relative to cow’s milk or may be high or low in protein. Other products have added sweeteners, which could contribute to an increased preference for sweetened foods as the children get older, he noted.

However, manufacturers of regulated infant products often market them alongside their infant formula, which can be confusing for parents and caregivers. The products often have similar names, images, slogans, and logos, and may suggest benefits such as immune system support, brain development, and digestive health, he added.

A 2020 survey published in Maternal and Child Nutrition found that 60% of approximately 1,000 caregivers of children aged 12-36 months agreed with the marketing claim that toddler formulas or powdered milks provide nutrition that is not available from other food and drinks, Dr. Fuchs said.
 

Balanced diet is best for healthy children

For infants younger than 12 months, the AAP recommends that the liquid portion of the diet should come from human milk or a standard infant formula that has been reviewed by the FDA based on the Infant Formula Act, Dr. Fuchs said.

Children aged 12 months or older should receive a varied diet with fortified foods. Formula can safely be used as part of a varied diet; however, it offers no nutritional advantage for most children over a well-balanced diet that includes human milk and/or cow milk, “and should not be promoted as such,” Dr. Fuchs noted.
