Early to mid-prenatal PM2.5 exposure, child lung function linked

Elevated fine particulate matter and nitrogen dioxide exposure in the early to middle weeks of pregnancy had links to lower lung function measures in offspring aged 8 to 14 years, according to results published in CHEST.
“We found that exposure to air pollution during mid-gestation is associated with lower lung function outcomes in childhood,” Maria José Rosa, DrPH, environmental epidemiologist and associate professor in the department of environmental medicine at the Icahn School of Medicine at Mount Sinai, told Healio.
In this study, Rosa and colleagues evaluated 429 mother-child pairs

Q&A: RADIOS consortium aims to understand cancer therapy irAEs

Three years after enrolling its first patients, a consortium of researchers examining the growing issue of immune-related adverse events due to immune checkpoint inhibitor cancer therapy released a bounty of data at ACR Convergence 2025.
The Rheumatology Adverse Events Due to Immunotherapy Observational Studies (RADIOS) consortium, created by researchers at Johns Hopkins University, enrolled its first patients in late 2022 and early 2023, according to Laura Cappelli, MD, MHS, of the division of rheumatology at Johns Hopkins University School of Medicine.
As of late 2025, the cohort has enrolled

Laws to keep guns away from distressed individuals reduce suicides, suggests study

In 2023, more than half of all suicide deaths in the United States involved firearms. "Red flag" laws—also called Extreme Risk Protection Orders or ERPOs—are designed to reduce these deaths by authorizing temporary firearm removal from individuals deemed at high risk of harming themselves or others. ERPO laws had been implemented in 21 states and the District of Columbia as of February 2025.

Gut bacteria may tip the balance between feeding tumors and fueling immunity

A new study reveals how bacteria in the gut can help determine whether the amino acid asparagine from the diet will feed tumor growth or activate immune cells against the cancer, according to researchers at Weill Cornell Medicine. This casts the gut microbiome, comprising the trillions of microorganisms that live in the intestine, as a central player in the body's response to cancer and to modern cancer treatments like immunotherapies.

Night owl or early bird: Chronotype can influence your health and muscle strength

Being more active in the morning or afternoon is not just a matter of personal preference. Chronotype, which is each person's biological tendency to function better at certain times of the day, can play a significant role in preserving muscle mass, as well as its quality and strength, and also in metabolic health. Understanding this relationship can help explain why not everyone responds the same way to the same health routines.
