Doctors at the Mayo Clinic reported that CAR-T cell therapy produced dramatic improvements in patients with stiff person syndrome, a rare autoimmune condition that affects the central nervous system. Patients who previously needed help with basic daily tasks have regained the ability to return to work and resume hobbies, with some reporting no episodes since treatment.

The results, published in Jama Neurology, suggest the therapy could offer a new treatment option for a disease that currently has no cure.

The FDA warned that GLP-1 drugs, including Ozempic, Wegovy, Mounjaro, and Zepbound, carry a potential risk for non-arteritic anterior ischemic optic neuropathy, a rare condition sometimes called an eye stroke. The agency required pharmaceutical companies to inform patients and doctors of this risk, which can cause sudden vision loss and potentially lead to blindness.

The warning follows the widespread use of these drugs for weight loss, where side effects may emerge in real-world use that were not observed in clinical trials.

Senior emergency doctors at the Queen Elizabeth University Hospital in Glasgow warned Healthcare Improvement Scotland that care delays are harming patients. They said the emergency department had deteriorated since their last review, undertaken in 2024, with staff moving patients from resuscitation areas into corridors because of sustained overcapacity.

Kent and Medway Mental Health NHS Trust is opening a 10-bed psychiatric intensive care unit for women at Littlestone Lodge in Dartford. The £4.63m facility will provide short-term, intensive care for women with serious mental health difficulties, with two beds also available to referrals from other NHS trusts.

The trust said the unit is expected to provide about 2,500 bed days a year and will welcome its first patient towards the end of November.

In the first randomized trial of double antiplatelet therapy for heart attacks with cardiogenic shock, 605 stent patients received cangrelor or crushed ticagrelor. Cangrelor was linked to a 73% lower chance of microvascular obstruction in an imaging substudy. At one year, it produced larger left ventricular ejection fraction gains: 37.9% versus 21.7% on ultrasound and 15.8% versus 2.1% on MRI.

Researchers including University of Cambridge scientists developed an mRNA treatment that temporarily activates Myc and Cyclin T1, helping heart muscle cells divide and repair damaged tissue. In mice after a heart attack, it increased blood pumped per heartbeat by around 10% versus mock treatment, with gains lasting at least 12 weeks. The team said it could help treat heart failure, diagnosed in about 200,000 people in the UK each year.

Researchers at the University of Eastern Finland found that among 2,546 men aged 42 to 60, a higher animal-to-plant protein ratio was associated with lower total testosterone levels. Men who reported the most plant protein from non-grain sources had higher free testosterone levels. The predominantly Caucasian cohort reported diets over four days, and the authors said the differences were small and did not establish health implications.

A KAIST-led team found that ZF2-4, a segment of a zinc finger protein, binds to amyloid-beta and suppresses its harmful aggregation in a mouse model of Alzheimer's disease. The treatment also reduced the toxicity of protein aggregates that had already formed. In experiments, the protein lowered amyloid-beta accumulation in the brain and improved recognition memory, suggesting a possible route toward new therapeutics.

Combat Medical reported real-world data showing 68% high-grade recurrence-free survival at 12 months in patients with BCG-unresponsive non-muscle invasive bladder cancer after hyperthermic intravesical chemotherapy with mitomycin C. The retrospective study of 150 patients was presented at the 18th European Multidisciplinary Congress on Urological Cancers. The data support HIVEC as a bladder-preserving alternative to radical cystectomy.

International liver experts have agreed on a unified definition for acute-on-chronic liver failure, aiming to reduce diagnostic confusion and treatment delay. Diagnosis requires a bilirubin level of at least 1.5 and an international normalized ratio of at least 5, followed by assessment of brain, kidney, circulatory or respiratory dysfunction. The group included five liver societies, pharmaceutical companies and regulators.

Researchers at KRIBB and Dong A University compared polyethylene and polypropylene nanoplastics with diesel exhaust particles in mice. Both plastic types caused acute lung inflammation, with relative potency depending on dose measurement. By surface area, both showed greater inflammatory potential than diesel exhaust particles. The particles increased reactive oxygen species in lung immune cells, suggesting they can disrupt immune responses.

Kyushu University researchers found that histone subvariant H3mm15 helps regulate gene expression during sperm development in mice. Mice lacking H3mm15 had disorganized seminiferous tubules, reduced sperm motility and altered expression of genes involved in the transition into meiosis. The protein differs from conventional H3.3 at three amino acids but forms less stable nucleosomes and shows more dynamic chromatin association.

A study co-led by UT Southwestern Medical Center found that antihypertensive medications combined into a single pill lowered blood pressure more effectively than multiple pills for patients in Jamaica and Colombia. The trial established the long-term effectiveness and safety of this approach for treating uncontrolled high blood pressure in low- and middle-income countries.

The results support the use of single-pill combinations to improve medication adherence and patient satisfaction.

Researchers analyzing data from 894 dogs in the Dog Aging Project examined DNA methylation patterns to understand why smaller dog breeds tend to live longer than larger ones. The study, with senior author Noah Snyder-Mackler of Arizona State University, looked at epigenetic changes that adjust gene expression without altering DNA sequences. The findings may offer clues about aging in dogs and humans.

A study by Mass General Brigham found that a single intravenous iron infusion improved exercise capacity in patients with heart failure with preserved ejection fraction and iron deficiency. Participants in the intervention group showed a 10% improvement in peak oxygen uptake at 12 weeks, while the placebo group saw no change. The findings suggest that replenishing iron could help address physical limitations associated with this condition.

A study by NYU Langone Health found that using HEPA air filters in the bedroom reduced exposure to air pollution and stabilized blood sugar levels in people with prediabetes. Participants who slept with real filters experienced a nearly 8% drop in daily blood sugar swings and smaller morning sugar surges. The findings suggest that cleaner air at home may be a low-cost tool to help protect heart and metabolic health.

A pooled analysis of 31 studies involving 243 people with lupus found that CAR T-cell therapy, originally developed for cancer, can lead to near-complete resolution of symptoms in patients with high disease activity. The study, presented at the American College of Rheumatology annual meeting, also noted an encouraging safety profile with mild side effects.

Researchers suggest the therapy could shift treatment goals from disease control toward sustained remission.

A follow-up study of the ISCHEMIA trial found that patients with stable heart disease who underwent early invasive procedures did not live longer than those treated with medications and lifestyle changes alone. The research, led by NYU Langone Health, showed that while procedures eased symptoms, death rates were nearly identical after nearly a decade.

The findings suggest that early intervention may not be necessary for all patients with stable coronary artery disease.

An Iranian hospital case control study compared 99 recently diagnosed cardiovascular disease patients with 396 controls without the condition. The researchers examined lifestyle areas including exercise, diet, stress management and social connections, and one lifestyle habit stood out as having the most pronounced differences. The study aimed to inform lifestyle changes that can lower rates of coronary heart disease and stroke.

Researchers in India tested whether visually appealing 'foodporn' images of healthy meals on Instagram could increase adolescents' interest in healthier eating. The BMC Public Health study involved 203 teenagers aged 13 to 19 and compared fast food images, plain healthy food images and stylized healthy food images. The work examines whether social media techniques that promote fast food can be redirected to support better diets.

The ZEUS clinical trial, led by Mass General Brigham researcher Paul Ridker, found that a drug targeting interleukin-6 (IL-6) did not reduce cardiovascular event rates compared to placebo. The findings, presented at the American Heart Association Scientific Session, challenge the assumption that targeting downstream inflammation is as effective as targeting other molecules.

Researchers suggest that the trial may have enrolled a different patient population than previous successful studies.

UT MD Anderson Cancer Center and P-Cure Ltd. have formed a strategic alliance to develop a next-generation particle therapy platform that delivers both proton and helium ion therapy. The collaboration aims to evaluate the clinical and operational potential of a dual-modality approach that allows physicians to select treatment based on patient disease characteristics.

If successful, the partnership would introduce the first helium particle system in North America.

A study of 9,000 organic Google results across 30 European countries found legitimate pharmacies predominated, but more than one in three retail links led to illegal vendors. For controlled substances, illicit sellers exceeded 76%, and illegal vendors were generally more visible among highly ranked results in countries prohibiting online medicine sales. The findings could inform policies to reduce exposure to illegal vendors.

A pilot study suggests that semaglutide or tirzepatide treatment may change eating behaviors, including food preferences and cravings, in adults with obesity. Participants lost an average of 7.2 kg over three months and reported changes in meal frequency and satiety. The findings provide preliminary evidence of behavioral changes during incretin-based treatment, though they do not establish that the medications directly caused them.

A report by the Sentinel Stroke National Audit Programme found that only 6.4% of stroke survivors in England, Wales, and Northern Ireland receive the three hours of daily rehabilitation therapy recommended by guidelines. The Stroke Association called the finding damning, noting that the average therapy time was just 40 minutes.

The report highlights a significant gap in care that hinders patients' chances of regaining physical and mental function.
