Today's health news covers a survey on breast cancer risk actions, a study on political vaccine perceptions, a call to invest in nursing for extreme heat, a model on C. diff transmission, altered heartbeat responses in iRBD, a thesis on tumor spatial organization, a Sardinian longevity hotspot, and an AI tool for skin lesions.

A new survey found that most U.S. women understood breast cancer risk factors, but only a minority were taking action to help lower their risk, according to Medical Xpress. The survey results highlight a gap between awareness and preventive behavior.

A study by Dr. Dror Walter and colleagues at Georgia State University examined political differences in perceptions of vaccine safety and effectiveness. Using data from a national probability sample of 1,763 U.S. adults surveyed in November 2024, the study was published online in the American Journal of Public Health on Sept. 10, 2026, Medical Xpress reports.

Penn Nursing's Center for Health Outcomes and Policy Research (CHOPR) published an editorial calling for hospitals to make nurse staffing and supportive work environments a core part of extreme heat emergency preparedness. The editorial appears in Public Health Nursing, as record-breaking temperatures and heat-related emergency department visits rise across the United States, according to Medical Xpress.

A new study modeled Clostridioides difficile (C. diff) transmission in hospital cancer units and found that most new infections were introduced by patients who were infected but not symptomatic at admission, rather than by symptomatic patients. The model provides a clearer picture of C. diff transmission events, Medical Xpress reports.

Research on isolated REM sleep behavior disorder (iRBD) found that brain responses to heartbeat are altered in patients. iRBD is characterized by strong physical reactions to vivid, often violent dreams and is one of the earliest warning signs of brain changes seen in Parkinson's disease or dementia with Lewy bodies, sometimes appearing years before diagnosis, according to Medical Xpress.

A doctoral thesis by Linglong Huang at the Karolinska Institutet's Department of Oncology-Pathology suggests that the spatial organization of cells in solid tumors may provide clinically relevant information about patient outcomes. The work links cells' spatial organization to cancer outcomes, Medical Xpress reports.

A terracotta-tiled village in the mountains of Sardinia may be a new longevity hotspot, offering researchers a rare opportunity to uncover the secrets of exceptional longevity, according to Medical Xpress.

An AI tool called MEL-IA (MobilE skin Lesion dIAgnosis) has been designed and integrated into hospital workflows to classify skin lesions. The University of Alicante and the Sant Joan d'Alacant University Hospital collaborated on the system. Skin cancer is a global health challenge, with nearly 1.5 million new cases diagnosed in 2024, according to World Health Organization (WHO) data, Medical Xpress reports.
