New CA19-9 threshold improves pancreatic cancer risk prediction accuracy

Rss Feed - Thu, 05/21/2026 - 03:07
A dual-threshold model for measuring the pancreatic tumor marker serum carbohydrate antigen 19-9 (CA19-9) identified patients with pancreatic cancer who had high-risk disease despite having low CA19-9 levels because of a genetic variation that impairs their ability to produce this biomarker.

A study published in Economic Inquiry provides new evidence that universal free school meals can meaningfully reduce out‐of‐school suspensions in both elementary and secondary schools.

Study defines realistic performance goals for pediatric emergency departments

Rss Feed - Thu, 05/21/2026 - 01:22
A large, multi-center study led by Ann & Robert H. Lurie Children's Hospital of Chicago derived "achievable benchmarks of care" (ABCs) using electronic health record data, which allows pediatric emergency departments across the country to set high yet realistic performance goals.

Oral AD109 improves sleep apnea severity but tolerability remains a challenge

Rss Feed - Thu, 05/21/2026 - 01:05
AD109, an investigational once-daily oral combination of aroxybutynin and atomoxetine, significantly improved airway obstruction and oxygenation in adults with mild-to-severe obstructive sleep apnea who could not use PAP therapy. However, symptom improvements did not clearly differ from placebo, and about one in five AD109 recipients discontinued treatment due to adverse events.

Polymer-based immunotherapies enhance tumor targeting and immune activation

Rss Feed - Thu, 05/21/2026 - 00:57
Conventional immune checkpoint inhibitors, such as anti-PD-1/PD-L1 and anti-CTLA-4 antibodies, can reinvigorate T cells but typically benefit less than 30% of patients.

GLP-1 drugs may help curb addiction by targeting reward pathways

Rss Feed - Thu, 05/21/2026 - 00:31
GLP-1 receptor agonists, already used for Type 2 diabetes and obesity, show promise in reducing alcohol and drug-seeking behaviors through central reward and dopamine-related pathways. Most evidence remains preclinical, with limited early human data, so larger clinical trials are needed before these drugs can be recommended for addiction treatment.

Calcium and vitamin D supplements show limited fracture prevention benefits

Rss Feed - Wed, 05/20/2026 - 23:25
Calcium, vitamin D, or combined supplements offer little to no clinically meaningful benefit on fracture and fall prevention in most older people, finds an in-depth review of the latest evidence published by The BMJ today.

How an AI system learned to write expert-level scientific code

Rss Feed - Wed, 05/20/2026 - 23:17
ERA is an AI system that uses large language models and tree search to automatically write, test, and refine scientific software for measurable research tasks. Across bioinformatics, COVID-19 forecasting, time-series analysis, geospatial modeling, neuroscience, and numerical computation, ERA produced expert-level solutions that often surpassed established human-developed methods.

Vigorous physical activity promotes lung growth in children, but these benefits are reduced by ozone pollution, according to new research presented at the ATS 2026 International Conference.

Minimal exposure to modern medicine rapidly alters the human microbiome

Rss Feed - Wed, 05/20/2026 - 23:00
Even minimal exposure to modern medicine can rapidly change the human microbiome. In a new study publishing May 20 in the Cell Press journal Cell Reports, researchers reveal that the gut microbes of remote Amazonian Indigenous communities began shifting toward patterns more commonly seen in urban, industrialized populations after only a few medical visits.

Poor sleep may flag early Alzheimer’s risk in genetically vulnerable older women

Rss Feed - Wed, 05/20/2026 - 22:05
Poorer subjective sleep quality was linked to worse visual memory and greater limbic tau burden in older women with higher genetic risk for Alzheimer’s disease. The findings suggest sleep complaints may help identify women at elevated risk for early AD-related brain and cognitive changes, but larger longitudinal studies are needed.
