Research published in JAMA Pediatrics found that neonatal mortality in Flint, Michigan, fell by 50 percent following the launch of the Rx Kids program, which provides financial support during pregnancy and infancy. Early neonatal mortality, defined as death within the first seven days of life, decreased by 74 percent.

The decline narrowed a longstanding disparity, making the difference in newborn survival between Flint and the rest of Michigan no longer statistically significant.

A Harvard study published in JAMA Psychiatry found that nearly half of drinkers taking GLP-1 medications reported declines in alcohol consumption. The effect was higher among individuals at risk of unhealthy alcohol use. The research, which surveyed a national panel of adults, explores an unexpected side effect of drugs used to treat diabetes and obesity, potentially offering a new avenue for addressing alcohol use disorder.

A study of 783,634 adult CT scans across 254 facilities found that nearly one in three scans exceeded the radiation threshold for their exam type. Facility scores for excessive dose ranged from less than 1 percent to more than 90 percent, with a typical gap of 74 percentage points between a facility's best and worst exam category.

The findings suggest that lower radiation doses are achievable with current equipment, as some facilities achieved near-zero out-of-range rates in categories where others struggled.

A University of California San Francisco team has begun a Phase 1 trial of repeated low intensity focused ultrasound aimed at the caudate, a deep brain region linked to auditory hallucinations. Up to 12 people with schizophrenia will receive five daily active sessions and five sham sessions, using a noninvasive wearable device from Attune Neurosciences. The study follows preliminary findings that one session produced temporary reductions.

Researchers at the University of Chicago and Fred Hutchinson Cancer Center found that a transfer RNA called tRNAArg (UCU)-1 helps advanced prostate cancer cells escape targeted therapies and become more aggressive. Published in Nature, the study says low levels of this small RNA act as a molecular switch during lineage plasticity, a process in which tumors lose dependence on androgen signaling. It may help resensitize resistant tumors to therapy.

UC San Diego and UC Riverside researchers identified new antiviral targets in coronaviruses by mapping SARS-CoV-2 RNA protein interactions. The team found binding sites for three viral proteins, NSP8, NSP12 and N, and showed that disrupting them significantly reduced viral replication. Published in Nature Communications, the work offers an early proof of concept for treatments less vulnerable to viral evolution.

A doctoral thesis from the University of Gothenburg reports that patients with diabetes-related foot ulcers often experience severe and unpredictable pain, a symptom that receives insufficient attention in the healthcare system. The study found that pain intensity varies significantly and can strike suddenly, disrupting sleep and daily planning.

Patients noted that healthcare staff do not always ask about pain, leaving many to manage their symptoms on their own.

A review in Trends in Endocrinology & Metabolism suggests that pregnancy temporarily speeds up the body's biological clock, and conceiving again before full recovery may contribute to cumulative aging. The authors propose a recovery period hypothesis, indicating that insufficient time between pregnancies could leave residual aging-related changes that affect long-term maternal health.

An international team led by Northumbria University developed and validated a five-factor dementia risk score for older people in low and middle-income countries, where about 60 percent of the world's dementia cases occur. The study, published in the American Journal of Epidemiology, used data from more than 11,000 older adults across seven countries and three continents. It uses a simple conversation, without blood tests, scans or equipment.

Scientists at St. Jude Children's Research Hospital identified how the METTL13 enzyme modifies a factor involved in mRNA decoding to promote tumor growth. Published in Nature Cell Biology, the study found that this modification promotes the efficient translation of codons enriched in oncogenes like KRAS, offering new targets for treating therapy resistance.

The American Academy of Dermatology highlighted the importance of the skin barrier during National Healthy Skin Month, noting that a damaged barrier allows germs to enter and causes moisture loss. The organization warned that factors like over-cleansing and harsh products can weaken this protective layer, worsening conditions such as eczema, psoriasis, and acne.

A child in Lewis County, New York, died after contracting measles, the state's first measles-related death in 30 years. Governor Kathy Hochul linked the death to federal immunisation policy. The CDC reported 4,588 US measles cases in 2026 as of late October, more than double 2025, and confirmed three US deaths this year; Pennsylvania reported six.

Scientists at the University of North Carolina Lineberger Comprehensive Cancer Center found that the innate immune protein cGAS also works in the nucleus to help control cholesterol and tumor behavior. Published in the Journal of Clinical Investigation, the study says cGAS increases LGALS3, reducing acetyl-CoA and cholesterol. Without cGAS, excess cholesterol can activate a growth pathway. It points to new therapy strategies.

Spain will allow women who live and work in Spain with incapacitating health problems linked to menopause to take specific medical leave from 1 December 2026, with benefits from the second day. A doctor must diagnose a condition associated with a secondary menopausal disorder that temporarily prevents work.

The government approved the reform on 20 October, extending protections that began with paid sick leave for incapacitating menstruation in 2023.

Eighty-five organizations, including Greenpeace International and the World Organization of Family Doctors, called on the World Health Organization to revise its nitrate drinking water guidelines. The groups argue the current limit, set in 1958 to prevent blue-baby syndrome, is outdated and does not account for recent evidence linking low-level nitrate exposure to colorectal cancer and adverse birth outcomes.

Researchers from City St George's, University of London, and University College London found that AI measurements of ejection fraction from heart MRI scans are more strongly linked to patient survival than clinician measurements.

The study, published in The Lancet Digital Health, analyzed scans from 27,382 patients and found the AI tool was both more accurate in predicting death risk and significantly faster, processing scans in seconds rather than minutes.

A study from Stony Brook University found that large language models can generate hospital discharge summaries that are more accurate and complete than those written by humans. In a comparison of 60 complex hospitalizations, physician reviewers preferred the AI-generated summaries in 95 percent of cases, citing higher quality, readability, and fewer missing clinical details.

A Yakima County, Washington, resident with previous health conditions died Sunday after being infected with H5N1 bird flu, the first US bird flu death in a year. County health officials said the person was exposed at a dairy with infected cattle and had been hospitalized. CDC said more than 70 US human infections have been reported since early 2024, with no known person-to-person spread and low general public risk.

Oregon Health & Science University researchers found that supplemental vitamin C during pregnancy may reduce emotional and mental health risks in infants whose mothers had higher prenatal stress. The study, published in Developmental Psychology, found stressed pregnant women tend to have lower vitamin C intake, and about 25 percent of US pregnant women consume less than required. The team called it a low-cost, accessible intervention.

St. Jude and Seattle Children's researchers, with the Children's Oncology Group, found that mutations in the original B-cell acute lymphoblastic leukemia tumor can be associated with relapse risk. Published in Blood, the study compared DNA from diagnosis and relapsed samples in 183 pediatric cases, the largest study of its kind. The findings could help estimate relapse risk before treatment, with mutation risk varying by subtype.

A survey of 50,000 people across 92 countries found that global mental health scores are declining, particularly among young people who report lower vitality, emotional stability, and resilience. The study, published in Social Indicators Research, noted that while older adults and people of all ages reported positive views on relationships and meaning, younger respondents lacked fundamental aspects of well-being.

Lead author Kai Ruggeri called the findings a flashing red light for policymakers to address specific factors like AI-driven job losses and burnout.

Researchers at UC Santa Barbara and UC San Francisco identified a set of proteins that change during the menopause transition and are linked to brain aging and dementia risk. Published in Nature Medicine, the study found that higher levels of these molecules in blood were associated with poorer cognitive outcomes and a modestly greater risk of Alzheimer's dementia over 16 years.

The team aims to develop a blood test that can serve as an early-warning sign of dementia risk, similar to cholesterol tests for heart disease.

Researchers at the University of Illinois Chicago have received a $1.2 million grant to study dentin phosphophoryn, a protein that helps build teeth. The team aims to understand how this protein protects dental pulp stem cells from calcium-induced stress, potentially allowing damaged teeth to repair themselves rather than requiring synthetic replacements.

Researchers at Johns Hopkins found that triptolide, a natural compound from thunder god vine, can help overcome resistance to DNA methyltransferase inhibitors in cancer cells. The compound blocks an enzyme that breaks down these drugs, allowing them to reactivate tumor suppressor genes and kill cancer cells in laboratory models.

Published in Nature Communications, the findings suggest a potential strategy for expanding the use of these therapies to more types of cancer, including solid tumors.

A global analysis using Global Burden of Disease data found that while pediatric stroke mortality has declined, the absolute burden remains high, particularly in low- and middle-income countries. In 2021, an estimated 2.7 million children and adolescents were living with pediatric stroke, with hemorrhagic stroke accounting for the majority of disability-adjusted life years and deaths.

Researchers reported the first published case of a patient with alpha-1 antitrypsin deficiency successfully treated with in vivo gene therapy. A liver biopsy confirmed high correction efficiency and no detectable off-target edits, converting the patient's genotype to a mosaic state that reduces disease risk.

The findings, published in the Journal of Hepatology, suggest a path toward permanent, minimally invasive treatments for hereditary liver diseases.

Preliminary research to be presented at the American Heart Association Scientific Sessions 2026 suggests that AI analysis of data from portable blood pressure monitors and wrist-worn devices can predict hypertensive crises up to three days in advance. The study found that continuous tracking of blood pressure patterns and cardiovascular signals helps identify adults with stage 2 high blood pressure at increased risk of dangerously high episodes.

This approach aims to provide early warning signs for a medical emergency that is a leading cause of heart-related emergency department visits.

A study of more than 71,000 Korean women found that eating sugary foods more than twice a week was linked to a 28% higher risk of breast cancer. Researchers at Seoul National University used data from the Health Examinees study and published the findings in the European Journal of Nutrition. The result adds to questions about diet as a modifiable breast cancer risk factor, especially as sugar intake remains high in many countries.

A long-term Israeli study of more than 52,000 women found contemporary hormone replacement therapy was not associated with higher risk of heart attack, stroke, blood clots or death among women aged 45 to 59. The findings will be presented at the American Heart Association Scientific Sessions 2026. Researchers said the results may help women and healthcare teams weigh menopause treatment.

A cross-sectional study of 615 adults in the Loma Linda Blue Zone area and surrounding Southern California communities found vegetarianism was more common among older adults and Seventh-day Adventist members. Vegetarians had significantly lower body mass index than non-vegetarians. The age-related differences raise questions about whether the region's traditional plant-based diet will persist.

A study in npj Clean Air modeled the 2018 and 2019 heatwaves in climates 2 degrees C and 2.75 degrees C above pre-industrial levels. Under the 2.75 degrees C scenario, ozone could fall in many regions and fine particles in some areas, while heatwaves may become longer and more severe. Researchers said heat-related deaths could rise more than pollution-related deaths fall.

A new analysis of eight Inca children sacrificed in capacocha rites found they had been given a variety of psychoactive drugs in the months to weeks before death. Traces of substances such as cocaine and alcohol have been found on multiple mummies. Researchers said the drugs may have helped the children endure the journey or served religious purposes.
