GLP-1 weight-loss drugs may change what you crave, not just how much you eat

A prospective observational pilot study of 38 adults without diabetes found that three months of semaglutide or tirzepatide treatment was associated with an average weight loss of 7.2 kg, reduced food cravings, increased satiety, and improved self-reported hunger control. Most participants reported smaller meal portions, while some experienced changes in food preferences, although the study could not establish whether the medications directly caused these behavioral changes.

Red meat and ultra-processed foods show no clear link to postpartum depression in new study

A prospective cohort study of 264 pregnant Iranian women found no statistically significant association between maternal consumption of ultra-processed foods or red meat and probable postpartum depression assessed four to six weeks after childbirth. However, the relatively small sample size and imprecise estimates mean that potentially meaningful associations cannot be excluded, highlighting the need for larger studies.

Frequent anxiety may reflect worsening cognitive function in Alzheimer's disease

Ask the family of someone with Alzheimer's disease what the hardest part is, and the answer is not always the forgetting. Sometimes it is the pacing.

Advanced tumor profiling uncovers hidden hereditary cancer-predisposition syndrome

Using next-generation sequencing (NGS) to profile tumor cells from patients with solid tumors, researchers at Fondazione Policlinico Universitario A. Gemelli IRCCS identified genetic alterations associated with cancer predisposition in 10% of the subjects examined.

Occasional male cannabis users experience stronger effects than women

Men who use cannabis occasionally reacted more strongly to smoked cannabis than women with similar use habits, even though the amount of THC in their blood was about the same, according to a new study from UCLA Health.

Routine pediatric lung therapies do not improve ventilator-free days

Results from the largest international clinical trial of its kind show that early, routine use of prone positioning and/or high-frequency oscillatory ventilation (HFOV) do not increase ventilator-free days for children with pediatric acute respiratory distress syndrome (PARDS).

Struggling with constipation? Two green kiwifruits a day may help

A narrative review of 33 publications found that consuming two fresh green kiwifruits daily for approximately four weeks can improve bowel movement frequency and gastrointestinal comfort in adults with functional constipation or constipation-predominant irritable bowel syndrome (IBS-C). Clinical studies reported broadly similar improvements with kiwifruit, psyllium, and prunes, although more research is needed to establish long-term benefits and differences between kiwifruit varieties.

Implantable AI signal processing optimizes adaptive deep brain stimulation therapy

A research team led by Professor Ji-Woong Choi of the Department of Electrical Engineering and Computer Science at DGIST (President Kunwoo Lee), in collaboration with research teams led by Professor Han-Joon Kim of Kumoh National Institute of Technology, Professor Kyong Hwan Jin of Korea University, and Dr. Jong-Cheol Rah of the Korea Brain Research Institute, has developed "NONOS," a deep-learning-based analysis technology that precisely separates "rhythms" from the underlying "background signals" in brain signals with high temporal resolution.

Graded physical activity prescriptions improve functional outcomes in psychiatry

Most of us have heard the advice so often that it has worn smooth, like a stone in a river: get some exercise. A new peer-reviewed Viewpoint in Brain Health, drawing on randomized trials, meta-analyses, and cohort studies, argues that this familiar sentence has been doing the wrong job.

Modern lifestyles may be changing our gut bacteria in unexpected ways

A global study of 1,015 adults across 12 countries found that industrialized lifestyles were associated with lower gut bacterial diversity, reduced microbial community stability, and increased markers of intestinal stress and immune activity. The researchers also found that a microbiome-based health index developed using industrialized populations performed poorly in less-industrialized communities, raising concerns about its applicability across diverse populations.

A study of 27,000 adults links bean products and soy compounds to lower kidney disease odds

A cross-sectional study of 27,003 adults in Northeast China found that higher consumption of processed bean products and soy isoflavones was associated with lower odds of chronic kidney disease, while plain bean intake showed no significant association. The relationship with soy isoflavones was stronger in women, although the observational findings cannot establish whether these foods protect against kidney disease.

Exercise may improve mood and memory, and researchers say doctors should prescribe it

In a Viewpoint, researchers examined evidence that exercise can reduce symptoms of depression and anxiety, support cognition, and may help lower the risk of cognitive decline, although evidence for dementia prevention remains largely observational. The authors argue that exercise should be prescribed as a structured component of brain-health care, with individualized recommendations that account for medical conditions, safety, and barriers to participation.

Online communication patterns impact adolescent mental health differently

In a study in Child and Adolescent Mental Health, researchers found that online communication with friends was associated with adolescents' mental well-being, but patterns varied by both frequency of communication and the type of friendship.

Researchers develop method to generate billions of cDC1 immune cells

Conventional type 1 dendritic cells, known as cDC1 cells, are immune cells that help initiate responses against intracellular pathogens and tumors.

Sporadic illness drives rising US campylobacteriosis incidence over two decades

Announcing a new article publication for Zoonoses journal. Campylobacteriosis is monitored by several U.S. surveillance systems, including the Foodborne Diseases Active Surveillance Network (FoodNet), the National Notifiable Diseases Surveillance System (NNDSS), and the National Outbreak Reporting System (NORS).

Eating sugary foods more than twice a week was linked to 28% higher breast cancer risk

In a prospective study of 71,264 Korean women followed for an average of 9.2 years, researchers identified 713 breast cancer cases and examined how different dietary sugar sources related to cancer risk. Women consuming high-sugar foods more than twice weekly had a 28% higher breast cancer risk than those consuming them no more than once a month, while total sugar intake and fruit consumption showed no significant association.

Two healthy diets stood out in a study of more than 7,000 adults

In a cross-sectional analysis of 7,256 adults from the Maastricht Study, researchers found that greater adherence to the DASH and Dutch Healthy Diet patterns was associated with higher very-low-frequency (VLF) heart rate variability power, particularly among participants not taking beta-blockers. No significant associations were observed across time-domain HRV measures after full adjustment, and the findings do not establish that these diets improve cardiovascular function.

New study links cannabis use to increased cardiovascular risk

Cannabis use, including marijuana, appears to be linked with increased cardiovascular risk, especially for stroke, making it an important consideration for heart disease and stroke prevention and counseling, according to independent, new preliminary research to be presented at the American Heart Association's Scientific Sessions 2026.

Could GLP-1 drugs help women with PCOS beyond weight loss?

A scoping review of 28 studies suggests that GLP-1 receptor agonists may improve androgen levels and menstrual function in women with polycystic ovary syndrome (PCOS), alongside their established metabolic benefits. Evidence for improved ovulation, fertility, and pregnancy outcomes remains limited, and the researchers could not determine whether reproductive benefits result directly from the drugs or from weight loss and improved metabolic health.
