Five days after Utah Gov. Spencer Cox signed a law meant to provide stronger oversight of the more than 100 residential youth treatment programs operating in the state, a 12-year-old boy arrived at one of them, Provo Canyon School.

A clinical trial funded by the National Institutes of Health has found that giving peanut oral immunotherapy to highly peanut-allergic children ages 1 to 3 years safely desensitized most of them to peanut and induced remission of peanut allergy in one-fifth. The immunotherapy consisted of a daily oral dose of peanut flour for 2.5 years.

Melanoma cells release small extracellular packages containing the protein nerve growth factor receptor, which primes nearby lymph nodes for tumor metastases, according to a new study by Weill Cornell Medicine investigators. The study results, published on Nov. 25 in Nature Cancer, may one day help doctors determine which patients need more aggressive treatment and could

Young children, toddlers, and infants infer that individuals who share saliva through activities like kissing, sharing food or wiping drool are in so-called “thick” relationships – intimate bonds that people often share with family members. The findings, based on experimental techniques from developmental science, reveal social clues youngsters use to inform their earliest understanding of

A new study published in Science Advances described the first two patients known to have mutations in both copies of BUB1, a critical gene for cell division. Contrary to previous thoughts, these mutations are compatible with life albeit associated with developmental problems. The identification and clinical/molecular characterization of such mutations could improve the diagnosis of

There is no evidence of recently infected mothers transmitting infectious SARS-CoV-2 through breastmilk to their baby, reports a study published in the journal Pediatric Research. The authors found that, whilst a low proportion of breastmilk contained COVID-19 genetic material, this did not translate into the presence of infectious replicating viral particles or lead to evidence

Many recreational cannabis companies market their products in a way that appeals to children and teens, despite state-based regulations prohibiting it, according to a new study in the Journal of Studies on Alcohol and Drugs.

A recent retrospective cohort study published on the medRxiv* preprint server found that the clinical severity of coronavirus disease 2019 (COVID-19) was lower in children younger than five years of age after the emergence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) Omicron variant in comparison to COVID-19 cases in this patient population when the SARS-CoV-2

Seeking to better understand the key role the female hormone estrogen plays in maintaining energy balance and weight control, a group led by researchers at Baylor College of Medicine looked into estrogen interactions with specific brain regions that provide these anti-obesity benefits. The team reveals in the journal Science Advances an estrogen-activated neurocircuit that stimulates

An investigational cancer drug that starves tumors of their energy supply also shows evidence of improving whole body metabolism, according to a new study in mice from Washington University School of Medicine in St. Louis. Shown are sections of liver from mice on a high-fat, high-sugar diet. On the left, more white space indicates greater

Heart function recovery returned within three months in children who developed COVID-19-related multisystem inflammatory syndrome (MIS-C), according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association. MIS-C is a new illness identified during the COVID-19 pandemic that affects children about four
