Researchers at the University of British Columbia have identified a new form of hereditary prostate cancer that, while rare, can cause aggressive disease at a young age.

Gut-friendly diet linked to lower mortality risk in coronary heart disease

Using NHANES 2005-2018 data, researchers found that adults with coronary heart disease who had higher Dietary Index for Gut Microbiota scores had lower all-cause mortality risk. The association was nonlinear, strongest when scores reached 5 or higher, and remained observational rather than causal.

New Italian data show extreme longevity is spreading beyond the blue zones

A nationwide ecological analysis of Italian regions found that aging and extreme longevity indicators rose steadily from 1982 to 2025, with northern and central regions generally leading. Regional patterns linked higher longevity indices to lower diabetes and cerebrovascular mortality and healthier contemporary nutrition profiles, while Cilento emerged as a notable southern hotspot.

Paternal postpartum depression affects more fathers than widely recognized

Postpartum depression in mothers is a widely recognized condition that affects 1 in 7 women. But less known is that 1 in 10 new fathers also experience depression.

Smoking shows no major impact on the eye microbiome in small study

A small study found no evidence that smoking causes large or consistent shifts in the ocular surface microbiome or tear proteome. The authors caution that subtle smoking-related effects cannot be ruled out, given the small cohort and the ocular surface's low-biomass, contamination-sensitive microbial niche.

Sleep apnea and erectile dysfunction share a stronger link than expected

A systematic review and meta-analysis of 8 observational studies found that greater obstructive sleep apnea severity was associated with poorer erectile function, with higher AHI linked to lower IIEF scores and higher minimum oxygen saturation linked to higher IIEF scores. The authors caution that the evidence remains observational, heterogeneous, and low certainty, so the findings support targeted screening rather than proving causality.

Yogurt, prebiotics, and probiotics link to lower colorectal cancer odds in U.S. adults

A national NHANES analysis of 9,405 U.S. adults aged 50 and older found that any yogurt, prebiotic, or probiotic consumption was associated with about 50% lower odds of self-reported colorectal cancer. Because the study was cross-sectional, it cannot prove causation but supports further research into microbiota-targeted dietary strategies.

New review shows why antidepressants often fail in Alzheimer’s and Parkinson’s depression

A Molecular Psychiatry review shows that depression in Alzheimer’s and Parkinson’s disease may reflect disease-specific molecular, neurotransmitter, inflammatory, and circuit-level disruptions rather than standard depression biology alone. It argues that broad antidepressants often show limited efficacy in these patients and that future trials should use biomarkers, neuroimaging, and symptom profiling to guide targeted treatments.

Updated ABCs framework gives clinicians a clearer path to prevent heart disease

A 2026 State-of-the-Art review updates the ABCs of cardiovascular disease prevention to help clinicians apply contemporary risk assessment, lifestyle, pharmacologic, and cardiometabolic strategies in routine care. The framework emphasizes PREVENT™ risk equations, Life’s Essential 8, CKM syndrome, obesity care, lipid lowering, blood pressure control, healthy aging, heart failure prevention, and atrial fibrillation management.

Breaking up long periods of sitting is linked to lower cancer risk

The study highlights that how sedentary time is accumulated affects cancer risk, with prolonged sitting linked to higher risk and activity offering protection.

Short sleep and poor sleep quality track with Parkinson’s risk

Using CHARLS data from 2011 to 2020, researchers found that sleep duration and self-reported sleep quality were associated with Parkinson’s disease risk in middle-aged and older Chinese adults. Short sleep was linked to higher PD risk, while age-specific patterns suggested a linear association in adults aged ≤60 years and a U-shaped relationship in those aged >60 years.

Study links geography to significant differences in sperm quality

A new nationwide study has found substantial regional differences in sperm quality, with men in the highest-performing region recording almost double the total motile sperm count of those in the lowest-performing region.

Air pollution may impact genes involved in sperm development

New research presented today at the 42nd Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) suggests that exposure to air pollution may impact genes associated with sperm development, raising new questions about male fertility, pregnancy outcomes and offspring health.

Meat and dairy cuts may improve health without raising food costs

A Scottish microsimulation study found that reducing meat and dairy intake, especially red meat among high consumers, could improve modeled health and environmental outcomes without increasing diet costs. However, some nutrient intakes, particularly calcium and iodine, declined, highlighting the need for carefully planned substitutions and fortified alternatives.

Men face higher risk of late-stage cancer diagnoses than women

Between 2015 and 2022, men were more likely than women to be diagnosed with regional and/or distant stages of 20 nonreproductive solid cancer types in the United States, according to a study published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research (AACR).

Some statins may increase erectile dysfunction risk

Research indicates that certain statins, particularly atorvastatin and simvastatin, may elevate the risk of erectile dysfunction, impacting men's health.

Allergies show a small but significant link to later cancer risk

A systematic review and meta-analysis of 28 cohort-based studies found a weak but statistically significant association between allergic diseases and later cancer incidence. The signal was strongest in the Western Pacific region and among people with asthma, but high heterogeneity and limited subgroup evidence mean the findings require caution.

AI model identifies where snoring starts in the airway

A new study developed a snore-source classification model that uses STFT spectrograms, pretrained CNN features, and an L2-regularized SVM to identify where snoring originates in the upper airway. Tested on the MPSSC dataset, the approach achieved a 67.1% test-set unweighted average recall, the highest value among the compared methods, but still needs external clinical validation.

Swiping-based dating apps show strongest ties to compulsive use and body dissatisfaction

A meta-analysis of 27 studies involving 21,263 adults linked swiping-based dating app use to small-to-moderate adverse mental health correlates, especially compulsive use, body image concerns, and appearance-related anxiety. General well-being was not significantly associated with app use in the primary analysis, and the authors stressed that mostly cross-sectional evidence cannot prove causality.

Dutch study shows why plant-based eating can miss key nutrients

A Dutch dietary modeling study found that replacing major animal-based protein sources with plant-based substitutes reduced protein, EAA, vitamin, and mineral intake across age groups. Older adults, adolescents, children, and women were especially vulnerable to shortfalls, highlighting the need for planned substitutions, fortified foods, and age-specific dietary guidance.
