Metabolic syndrome doubles worldwide over two decades

A global study reveals a sharp rise in metabolic syndrome prevalence from 2000 to 2023, highlighting urgent public health challenges and regional disparities.

Ultrasensitive assay uncovers hidden burden of tuberculosis disease

Researchers at Boston University have discovered an unexpectedly high prevalence of Mycobacterium tuberculosis DNA (TB DNA) in patients hospitalized in Boston, suggesting that tuberculosis disease may be significantly underdiagnosed in the United States.

Study finds top AI models still struggle with clinical reasoning

Researchers tested 21 frontier large language models on 29 stepwise MSD Manual clinical vignettes and found that, although many models performed well on final diagnosis, they remained much weaker at differential diagnosis and diagnostic testing. They also introduced the PrIME-LLM score, a multidimensional benchmark designed to better capture balanced clinical reasoning across the full workflow rather than raw accuracy alone.

Generative AI falls short in diagnostic reasoning despite accuracy

Despite increasing use of artificial intelligence (AI) in health care, a new study led by Mass General Brigham researchers from the MESH Incubator shows that generative AI models continue to fall short at their clinical reasoning capabilities.

Vaping may raise cognitive impairment risk in young adults, study finds

A cross-sectional study of 232 young adults in Bangkok found that e-cigarette users were more likely than non-smokers to screen as at risk for cognitive impairment on the MoCA, while no significant differences were seen for ADHD symptom tendency or emotional intelligence. The authors say the findings raise neurocognitive concerns but do not prove causation, and they call for longitudinal research to clarify whether vaping contributes to later cognitive decline.

Beckman Coulter Diagnostics earns CE mark for new assay delivering bacterial vs viral infection results in approximately 20 minutes

Beckman Coulter Diagnostics, a Danaher company and global leader in clinical diagnostics, today announced it has received CE 2797 mark under IVDR for the Access MeMed BV assay, enabling broad availability of a high-throughput host‑response test that helps clinicians differentiate between bacterial and viral infections in approximately 20 minutes.

Pseudogene lncRNAs regulate cancer stem cell behavior and signaling

Cancer stem cells (CSCs), a critical subpopulation within tumors, drive cancer initiation, progression, metastasis, relapse, and resistance to therapy due to their innate capacity for self-renewal and differentiation.

Study reveals immune aging differs significantly between men and women

Statistics show clear differences in the population's immune system according to sex: men are more susceptible to infections and cancers, while women have stronger immune responses, which translate, for example, into better responses to vaccines.

EV-RNAs show promise for IBD diagnosis and treatment

A research team led by Sir Run-Run Shaw Hospital, Zhejiang University School of Medicine, has published a comprehensive review in ExRNA that sorts out the diverse roles of extracellular vesicle-associated RNAs (EV-RNAs) in the development and progression of inflammatory bowel disease (IBD).

Lung tumors shift identity making treatment more difficult

A new study co-led by the Institute for Systems Biology (ISB) shows that some lung cancers can change identity as they evolve, shifting from one cancer type to another in ways that may make them more aggressive and harder to treat.

For many patients leaving the ICU, the struggle has only just begun

The accident happened in Pittsburgh on Nov. 16. Joseph Masterson, a lawyer who was just days from retiring at age 63, suffered cardiac arrest while driving, plowed into a guardrail, and lost consciousness.

IBS diagnosis gaps persist across racial and gender groups in the U.S.

A national survey study led by UCLA Health and Cedars-Sinai Medical Center found significant disparities in how irritable bowel syndrome, or IBS, is diagnosed across sex and racial groups in the U.S., with men and Black patients considerably less likely than women and white patients to receive a formal diagnosis.

Precision medicine tools offer hope for patients with rare blood cancers

Personalized approaches have dramatically improved outcomes for many patients with non-Hodgkin B-cell lymphomas—blood cancers that arise in immune cells called B cells—yet the same is not true for patients with more rare lymphoma types that originate in immune cells called T cells.

Self-employment linked to lower heart disease risks in Hispanic women

Self-employed Hispanic women report less high blood pressure, obesity, diabetes, poor health and binge drinking compared to Hispanic women working for salary or wages, new research suggests.

Sponge and sea slug partnership yields a new anticancer molecule with drug design promise

Researchers identified jorumycidine, a new hexacyclic marine alkaloid from the nudibranch Jorunna funebris and its dietary sponge, Haliclona sp., and demonstrated that it exhibits potent nanomolar cytotoxicity against multiple myeloma cells. They also proposed a new biosynthetic route involving cross-species metabolic interplay and an unusual oxazolidine ring that may help stabilize a pharmacologically important scaffold.

Why early-onset cancers are rising and how researchers plan to stop them

Early-onset cancers are rising worldwide, and this Cell Perspective argues that cancer prevention must move beyond static risk-factor snapshots toward life-course exposure mapping, tissue-level biology, and dynamic estimates of preventability. The authors propose three linked frameworks to speed discovery of cancer causes and translate those findings into more precise prevention and interception strategies.

New blood test spots four cancers and other diseases by stripping away healthy DNA noise

MethylScan is a new low-cost cell-free DNA methylome test that removes much of the healthy blood DNA background, helping rare disease signals stand out more clearly. In more than 1,000 people, it showed strong performance for detecting four cancers, classifying liver diseases, and identifying organ-specific damage.

New obesity definition could delay treatment and widen health gaps

The Lancet obesity framework aims to improve risk assessment but risks delaying treatment and deepening health inequities, according to recent evaluations.
