Integrated care needed for lifelong Polyendocrine Ovarian Syndrome management

Polycystic Ovary Syndrome, which has just been renamed Polyendocrine Ovarian Syndrome (PMOS), is the most common hormonal and metabolic disorder affecting women of reproductive age, impacting up to 13% of this population and contributing to nearly 40% of infertility cases worldwide.

Surgical training program for community health officers slashes maternal mortality risk

Maternal mortality in Sierra Leone used to be among the highest in the world. A 15-year-old non-profit program that trains community health officers to do life-saving surgeries has helped slash that risk by two-thirds.

Chia seeds may boost fetal brain DHA during obesity-linked pregnancy

Chia seed supplementation during pregnancy increased maternal omega-3 long-chain fatty acids, including DHA, in a rat model of high-fat-high-sugar diet-induced obesity. The findings suggest plant-derived ALA from chia seeds may improve maternal, placental, and mid-gestation fetal brain lipid profiles, but human relevance and offspring outcomes still need testing.

Vaginal birth after cesarean more common at Black-serving hospitals

Low-risk patients at predominantly Black-serving hospitals (BSH) who previously gave birth through Cesareans are likelier to attempt and successfully deliver vaginally in a subsequent pregnancy than they are at hospitals treating few Black patients, new UCLA-led research finds.

Targeted radiotherapy may delay progression in metastatic breast cancer patients

Treating breast cancer that has begun to spread around the body with targeted radiotherapy could help patients to live longer without their cancer getting worse, according to the results of a small randomised controlled trial presented at the Congress of the European Society for Radiotherapy and Oncology (ESTRO 2026).

Prenatal chemical mixtures may influence fetal growth and placental health

Common environmental chemicals could affect birthweight and placental function, according to a new study published in Environmental Science & Technology and led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by "la Caixa" Foundation. Conducted within the Barcelona Life Study Cohort (BiSC), the research underscores the importance of considering real-life exposure to complex chemical mixtures and highlights the role of angiogenic biomarkers in linking these exposures to fetal development.

New research reassures mothers on NSAID safety during the first trimester

Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen, taken during the first trimester of pregnancy are not associated with an increased risk of major birth defects, according to a new study published May 14th in the open-access journal PLOS Medicine by Sharon Daniel of Ben-Gurion University of the Negev and Clalit Health Services, Beer-Sheva, Israel, and colleagues.

Maternal occupations linked to increased autism diagnosis odds

Findings indicate that certain maternal jobs are associated with increased autism odds in children, highlighting the importance of prenatal occupational health.

Perimenopause nearly doubles women’s odds of poor heart health

Perimenopause is linked to worsening cardiovascular health, with significant declines in lipid and glucose scores, emphasizing the need for early assessment.

Healthy plant-based foods may improve pregnancy cardiometabolic markers

Higher-quality plant-based diets were associated with more favorable cardiometabolic biomarkers in pregnant U.S. women, especially higher HDL-C and lower TG/HDL-C ratio. Indices that emphasized healthy plant foods, rather than simply penalizing animal foods, showed the strongest links with insulin resistance and lipid markers.

Can supplements slow Parkinson’s disease? Review reveals where the evidence stands

Dietary supplements are widely used by people with Parkinson’s disease, but this review finds that none have yet been proven to slow disease progression. Biotics, nicotinamide riboside, and omega-3 fatty acids combined with vitamin E show the most promise, but larger, longer, and better-designed trials are needed.

The Goldilocks sleep zone: study links too little and too much sleep to biological aging

The Nature study introduces “Sleep Chart,” a framework linking self-reported sleep duration with 23 biological aging clocks derived from MRI, plasma proteomics, and metabolomics. Across UK Biobank participants, the lowest biological age gaps generally appeared between 6.4 and 7.8 hours of sleep, while shorter and longer sleep were associated with higher disease and mortality risk.

Regular arts and physical activity linked to slower aging

Research shows that leisure activities, including arts engagement and physical exercise, are linked to slower epigenetic aging and improved health outcomes.

Gene panel predicts chemotherapy response in triple-negative breast cancer

Researchers at The University of Texas MD Anderson Cancer Center have characterized cancer cell-specific features in the tumor microenvironment (TME) of early-stage triple-negative breast cancer (TNBC) tissues, identifying specific macrophage subtypes associated with chemotherapy response.

Tranexamic acid modestly reduces bleeding after cesarean delivery in women

Giving tranexamic acid to women with placenta praevia (when the placenta covers the cervical opening) undergoing cesarean birth leads to a significant yet modest reduction in severe bleeding after delivery with no evidence of an increase in serious adverse events, finds a trial from China published by The BMJ today.

Brain-controlled hearing aid concept helps solve the cocktail party problem

Researchers developed a real-time brain-controlled hearing system that uses neural signals to identify and amplify the speaker a listener is focusing on in noisy, multi-talker environments. Using intracranial brain recordings, the system improved speech intelligibility, reduced listening effort, tracked attention shifts, and provided a benchmark for future brain-guided hearing aids.

Pregnancy not linked to increased myasthenia gravis flare-up risk

For female participants with myasthenia gravis, pregnancy is not associated with an increased risk of serious flare-ups of the disease, or new or worsening symptoms, according to a study published May 13, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Why experts say PCOS needs a new name

A Lancet Health Policy paper reports an international consensus process that selected polyendocrine metabolic ovarian syndrome (PMOS) as the new name for polycystic ovary syndrome (PCOS). The change aims to shift the focus away from ovarian cysts and better reflect the condition’s endocrine, metabolic, and ovarian features.
