Coffee drinkers had fewer repeat blood clots in a Norwegian study

A Norwegian study involving 2,071 patients found that those who reported drinking 1 to 2 cups of coffee daily before their first venous thromboembolism had a 51% lower estimated risk of recurrence than non-drinkers. The association was strongest among patients whose initial blood clot was provoked, although the observational study could not establish that coffee consumption prevents recurrence.

A study of 2.3 million California children raises questions about lithium in water

Researchers analyzed healthcare records from more than 2.3 million children in California and found that those living in counties with higher lithium concentrations in water sources had 60% higher adjusted odds of a Wolff-Parkinson-White (WPW) diagnosis. A separate New York analysis supported an association at a lower lithium threshol

Sex hormones dictate how skin stem cells renew themselves

For a long time, differences between females and males were mainly associated with the reproductive organs. Yet organs that have nothing to do with reproduction, such as the skin, can also be shaped by sex.

Novel bioprinting technique successfully replicates mature human fat tissue

A research team has developed a support-bath bioprinting method that enables fragile, mature human adipocytes to be incorporated into geometrically defined three-dimensional (3D) constructs while retaining their viability, characteristic lipid-filled morphology, and metabolic activity.

Investigational knee injection targets cartilage loss in osteoarthritis patients

Keck Medicine of USC has launched a clinical trial testing the safety and tolerability of a new investigational treatment and its potential effects on preventing cartilage deterioration in people with knee osteoarthritis, the most common form of the disease.

Doctors avoided two common words when talking about weight with patients

Researchers analyzed 123 recorded primary care consultations involving adults with type 2 diabetes and elevated BMI, finding that weight was discussed in just 39% of visits. Clinicians avoided potentially stigmatizing terms such as "overweight" and "obesity," while weight-related conversations occurred more frequently among patients taking GLP-1 receptor agonists.

Pancreatic cancer cells continuously reshape DNA to evade treatment

A new analysis of nearly half a million cells from dozens of pancreatic tumors, led by researchers at UC San Diego Moores Cancer Center and New York University (NYU), reveals how pancreatic cancer cells continuously reshape their genetic makeup over time, enabling them to evade treatment.

Consumer smartwatch helps identify adults with severe sleep apnea

New research suggests that a consumer smartwatch can help identify adults with moderate-to-severe obstructive sleep apnea, offering a way to screen for a common sleep disorder that often goes undiagnosed.

Targeting the RUNX1 gene helps reduce severe skin fibrosis

Skin fibrosis includes hypertrophic scar (HTS), keloid scar (KS), and systemic sclerosis (SSc). These conditions share persistent fibroblast activation, excessive extracellular matrix (ECM) deposition, and progressive skin remodeling.

Three months of yoga before surgery revealed a surprising difference in stress hormones

In a non-randomized study of 40 adults with severe obesity awaiting bariatric surgery, researchers found significantly lower plasma noradrenaline levels in yoga participants than in controls after adjusting for baseline measurements. The researchers detected no significant DNA methylation changes in three inflammatory genes and found no clear psychological or metabolic benefits.

Updated tinnitus guideline outlines research-based strategies for patient care

The American Academy of Otolaryngology–Head and Neck Surgery Foundation (AAO-HNSF) today published the Clinical Practice Guideline (CPG): Tinnitus Update in Otolaryngology–Head and Neck Surgery.

Study reveals continued care delays among patients with young-onset breast cancer

In an analysis of data on adolescents and young adults with breast cancer, lower income and younger age were linked with delays in care.

Diet drinks showed no clear weight-loss edge over water after two years

In a two-year randomized trial combining assisted weight management with an unassisted follow-up year, completers maintained average weight losses of 4.8 kg with diet drinks and 3.7 kg with water. Researchers found no significant difference between groups, but fewer than half of the 493 participants completed follow-up.

16-year study links worsening vision to higher dementia risk

Researchers followed 15,576 older adults in Hong Kong for up to 16 years and linked moderate to severe visual impairment to higher dementia risk, with rapid visual decline strengthening the association at poorer levels of vision. They estimated that severe impairment corresponded to 2.1 fewer dementia-free years over the study period, but could not establish that correcting vision prevents dementia.
