PSMA PET/CT scans may predict prostate cancer recurrence, guide treatment

New research in the February 2026 issue of JNCCN-Journal of the National Comprehensive Cancer Network found that incorporating information from prostate-specific membrane antigen (PSMA) PET/CT scans may be able to predict progression-free survival (PFS) and guide treatment planning in patients with rising prostate-specific antigen (PSA) levels following removal of the prostate.

IRF7 reshapes the behavior of vascular smooth muscle cells during atherosclerosis

Atherosclerosis underlies most heart attacks and strokes and is now recognized as a chronic inflammatory disease rather than a simple disorder of cholesterol deposition.

Cannabis legalization may lead to a decline in daily opioid use

Legalizing cannabis for both medical and recreational use may lead to a decline in daily opioid use among people who inject drugs in the United States, according to a new study led by a Boston University School of Public Health researcher (BUSPH).

Cognitive speed training shows potential to delay dementia for two decades

Adults age 65 and older who completed five to six weeks of cognitive speed training - in this case, speed of processing training, which helps people quickly find visual information on a computer screen and handle increasingly complex tasks in a shorter time period - and who had follow-up sessions about one to three years later were less likely to be diagnosed with dementia, including Alzheimer's disease, up to two decades later, according to new findings published today in Alzheimer's & Dementia: Translational Research and Clinical Interventions.

Historical redlining's impact on breast cancer survival changes over time

Historical redlining, a 1930s–1960s residential segregation policy, has been linked to shorter survival time in people with breast cancer.

Research sheds light on the UK's growing synthetic opioid problem

Deaths due to synthetic opioids nitazenes have likely been underestimated by up to a third.

Chronic alcohol use profoundly alters gene expression in the brain's reward system

Chronic alcohol consumption profoundly alters gene expression in key brain regions involved in reward, impulse control, and decision-making, according to a study led by researchers at the Institute for Neurosciences, a joint center of Miguel Hernández University of Elche (UMH) and the Spanish National Research Council (CSIC).

Intense exercise proves more effective for panic disorder treatment

Panic attacks are sudden bouts of intense fear without an obvious cause. An estimated 10% of people experience at least one panic attack in their lifetime.

Most statin side effects are not backed by trials

Research indicates that many statin therapy side effects are not supported by evidence, suggesting a need for revised labeling to improve treatment decisions.

Late sleepers have higher heart risk, and it's mostly preventable

Researchers explore the association between an individual’s chronotype and cardiovascular risk.

UK air ambulance critical care expands but unequal access still limits lifesaving treatment

A national UK survey found physician-based helicopter emergency medical services have expanded substantially since 2009, with more teams and improved overnight coverage. However, geographic and time-of-day disparities persist, and variation in funding, staffing, and interventions continues to affect equitable access to advanced prehospital care.

Large Swedish study finds COVID-19 vaccination unrelated to fertility or childbirth rates

A Swedish registry-based cohort study evaluated whether COVID-19 vaccination affected childbirth rates among women aged 18 to 45 years during the pandemic period. No statistically significant association was found between vaccination, childbirth, or recorded miscarriage rates, suggesting demographic and socioeconomic factors likely explain observed fertility trends.

High-quality family dinners reduce teen substance use risk yet severe adversity blunts the benefit

Higher-quality family dinner interactions were associated with lower adolescent alcohol, vaping, and cannabis use in a U.S. survey of parent–adolescent dyads. This protective association was evident mainly among adolescents with low or moderate adverse childhood experiences, but not those with high adversity exposure.

AI stethoscope doubles detection of serious valve disease in primary care study

A prospective primary care study found that an AI-enabled digital stethoscope substantially improved sensitivity for detecting clinically significant valvular heart disease compared with standard auscultation. The technology identified more previously undiagnosed moderate-to-severe disease but showed reduced specificity, highlighting a trade-off between earlier detection and potential false positives.

Early tuberculosis treatment reduces sepsis deaths in HIV patients

Sepsis is a leading global cause of hospital deaths, occurring when the body's response to infection damages tissue and causes organs to fail. Africa bears the world's highest burden of sepsis, with an estimated 48 million cases each year leading to about 11 million deaths.
