Four distinct subgroups of polycystic ovary syndrome (PCOS) have been identified in an international study published in Nature Medicine by researchers from Karolinska Institutet, among others.

With populations aging rapidly worldwide, heart failure has become one of the most pressing medical and social challenges.

During heatwaves, there is an increase in the number of people suffering with obstructive sleep apnoea (OSA), according to a major study published today (Wednesday) in the European Respiratory Journal.

​Treating patients at home with IV antibiotics, rather than in a clinical setting, could halve costs to the NHS and relieve pressure on hospital beds - according to a University of East Anglia study.

This review highlights hydroxytyrosol's role as a neuroprotective agent, activating key pathways for mental and vascular health through olive-derived compounds.

Findings on human visual resolution reveal that eyes reach detail limits before 8K displays, impacting future display and video coding technologies.

Using targeted radiation during surgery - referred to as intraoperative radiation - to eliminate pancreatic cancer cells that have spread to areas around the pancreas, investigators at Johns Hopkins have been able to reduce the recurrence rate around the pancreas to 5%.

Children and adolescents in North East England still find energy drinks easy to access despite a voluntary UK ban, drawn by taste, price, and powerful marketing. Hydration drinks like PRIME are viewed as “healthier,” even though young consumers often misunderstand their ingredients and health impacts.

A new review in Open Forum Infectious Diseases links animal agriculture to climate change, antimicrobial resistance, and infectious disease spread. The authors urge healthcare providers to promote plant-based diets as a practical step to protect planetary and public health.

Researchers analyzing over 85,000 UK Biobank participants found that women gain greater cardiovascular benefits from physical activity than men, needing only half the exercise to achieve similar reductions in coronary heart disease and mortality risk. The study underscores the importance of sex-specific guidelines for CHD prevention.

Researchers have developed LifeClock, an AI-driven biological clock trained on over 24 million electronic health records to estimate biological age across the human lifespan. The model accurately predicts disease risk years in advance, revealing distinct developmental and aging processes.

A new trial shows that a wireless subretinal implant, the PRIMA system, restored central vision in patients with geographic atrophy caused by age-related macular degeneration. After one year, 81% achieved clinically meaningful vision gains and most could read at home using prosthetic vision.

Neurodegenerative diseases (NDs), such as Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and multiple sclerosis (MS), represent a growing global health burden, particularly in aging populations.

Researchers have discovered how newly created neurons depend on blood flow in the adult brain to travel from their site of origin to their final location.

Frailty is closely linked to adverse outcomes in older adults, particularly those with heart failure. Numerous epidemiologic studies show that frailty has important prognostic value in this population, underscoring the need for routine assessment.

New study findings show that utilizing super-high-pressure non-compliant balloons (NCB) is non-inferior to intravascular lithotripsy (IVL) balloon catheters for lesion preparation and stent expansion in severely calcified lesions during percutaneous coronary intervention (PCI).

Results from the first randomized clinical trial in the United States to compare a sirolimus-eluting balloon (DEB) to control group consisting of drug-eluting stent (DES) and balloon angioplasty (BA) for the treatment of bare-metal and DES in-stent restenosis (ISR) deemed DEB to be noninferior to conventional therapies.

Results from the first randomized controlled trial to directly compare the safety and efficacy of cutting balloon (CB) angioplasty to intravascular lithotripsy (IVL) prior to drug-eluting stent (DES) implantation for the treatment of calcified coronary artery disease found CB to be noninferior to IVL.

The COVID-19 pandemic has provided researchers with a wealth of information on contemporary successes and failures in combating an emerging pathogen.

The Icahn School of Medicine at Mount Sinai is pleased to announce it has received a three-year, $4.5 million grant from BD2: Breakthrough Discoveries for thriving with Bipolar Disorder to investigate the neural mechanisms underlying bipolar disorder and pioneer novel neuromodulation-based treatment strategies.
