Coastal living adds years to your life while inland waters may cut them short

Proximity to coastal waters is linked to longer life expectancy in the US, while living near large inland water bodies often reduces it, except in rural settings, where the effect is positive. Environmental quality, income, and context drive these differences.

Understanding cow’s milk allergy in breastfed infants

Cow’s milk allergy (CMA) affects up to 2.2% of infants, with a complex interplay of immunological mechanisms, allergen transfer via breast milk, and variable responses to maternal elimination diets. Current evidence challenges the routine use of maternal dietary restrictions, highlighting the need for precise diagnosis and further research.

New clinical practice guideline advances surgical care for chronic rhinosinusitis

The American Academy of Otolaryngology–Head and Neck Surgery Foundation (AAO-HNSF) published the new Clinical Practice Guideline (CPG): Surgical Management of Chronic Rhinosinusitis today in Otolaryngology–Head and Neck Surgery.

Air pollution’s chemical punch alters immune markers in pregnant women, study finds

Personal exposure to nitrogen dioxide and the oxidative potential of fine particulate matter (PM2.5), but not PM2.5 mass, influenced immune biomarker levels in pregnant women. These findings suggest that the chemical reactivity of air pollutants may play a key role in maternal and fetal immune health.

Mild winter temperatures offer surprising mental health benefits

Higher ambient temperatures during the cold season were linked to reduced stress, improved life satisfaction, better self-reported health, and less loneliness in a large Swiss population study. While effects were modest at the individual level, they highlight the broader mental health impacts of seasonal temperature changes.

Eating kombu daily enhances gut health and heart markers in men

A 12-week randomized trial found that daily intake of boiled kombu (Laminaria japonica) powder reduced body fat and raised adiponectin in Japanese men, while improving blood pressure and gut microbiota in both sexes. No significant effects were seen in women for body fat reduction or adiponectin.

Vegetarians may need to watch thyroid health, especially with low iodine intake

Vegetarians had a modestly higher risk of developing hypothyroidism compared to high meat-eaters, but only after adjusting for BMI. No increased risk was seen for vegans or pescatarians in incident cases, though pescatarians showed a slight increase in baseline prevalence.

Using gas stoves at home significantly increases cancer risk

A new study in the Journal of Hazardous Materials modeled benzene emissions from the top 5% of gas stoves in U.S. homes, finding elevated cancer risks, especially for children, in poorly ventilated spaces. Using validated simulations, the researchers estimated up to 69 additional leukemia cases annually under high-use, unventilated scenarios.

Study shows no connection between PM2.5 spikes and major cardiovascular events

A Danish cohort study investigated whether long-term exposure to repeated monthly peaks of fine particulate matter (PM2.5) raises the risk of major adverse cardiovascular events. Despite higher PM2.5 peak exposure among affected individuals, no significant association with cardiovascular risk was found.

Phthalates in plastics linked to over 350,000 heart deaths worldwide

A global modeling study in eBioMedicine links phthalate exposure from plastics, especially DEHP metabolites, to over 356,000 cardiovascular deaths in 2018. Exposure was highest in Asia, the Middle East, and Africa, disproportionately affecting lower-income countries.
