Heavy menstrual bleeding linked to iron deficiency in teenage girls

More than half of teenage girls experienced heavy bleeding and 40 per cent had an iron deficiency. The research, led from Lund University in Sweden, also shows that young teenage girls who experience heavy menstrual bleeding – and are therefore at greater risk of iron deficiency – can be identified using a simple questionnaire.

Research reveals how the gut microbiome supports successful pregnancy

Gut microbes may play a key role in training a mother's immune system to adapt to the developing fetus during pregnancy, according to a preclinical study by Weill Cornell Medicine investigators.

Intermittent fasting edges daily calorie cuts for blood pressure and long-term cardiovascular risk estimates

In a real-world registry study of adults with overweight or obesity, 5:2 intermittent fasting and daily calorie restriction both improved blood pressure over 12 weeks. Intermittent fasting produced modestly greater reductions in systolic and pulse pressure and a larger drop in BMI-based 30-year cardiovascular risk scores, without superior lipid or glycaemic effects.

Plant-based omega-3s work better than expected in a year-long diet study

A year-long, diet-controlled intervention shows that flaxseed oil–derived alpha-linolenic acid significantly increases erythrocyte EPA, DPA, and DHA across omnivorous, vegetarian, and vegan diets. The magnitude of improvement is driven mainly by baseline omega-3 status, while absolute EPA and DHA levels in vegans remain lower than in omnivores.

New ultrasound method accurately distinguishes fluid from solid breast masses

New ultrasound technology developed at Johns Hopkins can distinguish fluid from solid breast masses with near perfect accuracy, an advance that could save patients, especially those with dense breast tissue, from unnecessary follow-up exams, painful procedures and anxiety.

Study shows iCTG improves perinatal outcomes in resource-constrained settings

Ninety-nine percent of global newborn deaths occur in low- and middle-income countries (LMICs), where pregnant women often struggle to access adequate fetal monitoring. In Tanzania, with 24 neonatal deaths per 1000 live births, a new wireless fetal heart rate monitoring technology is showing promise in preventing newborn complications and deaths.

How Traditional Chinese Medicine may reshape the gut microbiome to ease insulin resistance in PCOS

This review synthesizes evidence that gut microbiota dysbiosis contributes to insulin resistance and symptom severity in polycystic ovary syndrome through impaired barrier function, inflammation, and altered microbial metabolites. It evaluates how Traditional Chinese Medicine may modulate these pathways while highlighting major gaps in clinical validation, safety, and standardization.

Indoor tanning loads normal skin with mutations linked to melanoma

Indoor tanning is associated with markedly higher mutation burdens and cancer-driving genetic changes in melanocytes taken from normal-appearing skin, including areas usually protected from sunlight. These molecular alterations provide a biological explanation for the higher odds of melanoma and multiple primary tumors seen in heavy tanning bed users.

A new trial investigates whether the MIND diet can be scaled for obesity management

This study protocol outlines a 12-week randomized trial testing whether a MIND diet intervention is feasible, acceptable, and sustainable for adults with obesity in Sweden. It will generate preliminary evidence on adherence, mental well-being, and gut microbiota changes to inform larger efficacy trials.

E-cigarette use is linked to higher heart attack risk, especially in former smokers

This systematic review and meta-analysis examined whether electronic cigarette use is associated with myocardial infarction and stroke, synthesizing evidence from 12 observational studies. The analysis found higher odds of myocardial infarction among e-cigarette users, particularly former smokers, while no significant associations were observed among exclusive never-smokers.

Metabolic syndrome affects nearly four in ten US adults as rates climb in older and Black populations

A large NHANES analysis found that nearly four in ten US adults met criteria for metabolic syndrome between 2013 and 2023, with no statistically significant change in overall prevalence. However, prevalence rose significantly among adults aged 60 years and older and among non-Hispanic Black individuals, alongside a significant non-linear increase in hypertriglyceridemia.
