Personalized mobile health coaching reduces gestational diabetes among pregnant women

A continuous, personalized mobile health (mHealth) coaching programme can significantly reduce gestational diabetes incidence among high-risk pregnant women, independent of changes to maternal weight - according to an international study published today in the Lancet Digital Health.

Your plant-based dairy swaps could leave you short on iodine

A UK dietary model links dairy reduction to greater iodine inadequacy, highlighting iodized bread and fortified plant-based alternatives as policy options.

Single-cell spatial atlas profiles 850,000 cells across breast cancer progression

Researchers at The University of Texas MD Anderson Cancer Center have created one of the most detailed maps to date of the cell environment surrounding ductal carcinoma in situ (DCIS), the most common form of preinvasive, or stage 0, breast cancer.

Multicenter trial validates continuous pregnancy-to-postpartum mobile health coaching program

A continuous, personalized mobile health (mHealth) coaching program can significantly reduce gestational diabetes incidence among high-risk pregnant women, independent of changes to maternal weight – according to an international study published today in the Lancet Digital Health.

Your fitness may say less about cellular aging than you think

In a study of 84 middle-aged adults, researchers found that higher perceived stress and older age were associated with shorter telomeres, while physical fitness, body composition, and lifestyle habits showed no consistent independent associations. The findings suggest that telomere length may reflect psychosocial and health-related burden more closely than current physical performance, although the reported chronic disease association requires clarification because of an inconsistency in the paper's statistical coding.

Your BMI might not tell the full story about obesity, new research suggests

A study of 6,978 middle-aged UK adults found that nearly 69% of those classified as having obesity by BMI met the criteria for preclinical rather than clinical obesity under a new diagnostic framework. Clinical obesity was associated with higher five-year mortality odds, while conventional BMI categories showed no statistically significant associations, although the small number of deaths limits the strength of these findings.

A 43-gram sugar gap separates adults who check food labels from those who rarely do

A nationally representative US study of 9,416 children and adults found that frequent nutrition label users consumed an average of 42.8 g less added sugar daily among adults and 14.5 g less among children compared with infrequent users. The findings suggest an association between checking nutrition labels and lower added sugar intake, although the observational study could not establish causation.

A 12-year study links longer TV viewing to faster kidney function decline

A 12-year study of 6,220 Australian adults found that longer daily television viewing was associated with faster kidney function decline, with a stronger association among people with type 2 diabetes. Exploratory analyses suggested that women and physically inactive individuals may also be more affected, although some findings were inconsistent and the observational study could not establish causation.

A study of 844,000 adults reveals what BMI misses about obesity

A multinational study of 844,108 adults found that combining BMI with waist measurements improved obesity classification and identified mortality risks that BMI alone could miss. Clinical obesity was associated with a 69% higher all-cause mortality hazard, compared with 19% for preclinical obesity, while most participants with preclinical obesity were not estimated to progress to clinical obesity during long-term follow-up.

Researchers uncover how surrounding cells fuel triple-negative breast cancer growth

Triple-negative breast cancer, which accounts for approximately 10–15% of all breast cancer cases, is considered particularly difficult to treat because it grows rapidly and carries a high risk of recurrence.

Researchers identify promising new immune target for treating endometriosis

Affecting 200 million women of reproductive age, endometriosis is a chronic inflammatory disease that causes pain, infertility, and increased ovarian cancer risk.

Yale Cancer Center offers team-based care for breast cancer patients

Hilary Axtmayer can pinpoint the moment her life changed. In 2023, Axtmayer-then a 40-year-old mother of two from Madison, Conn.-was receiving her regularly scheduled breast exam when her gynecologist paused mid-palpation. She'd found a lump.

Proton therapy radiation patterns may increase breast implant complications

Radiation therapy is sometimes needed after mastectomy and breast reconstruction for breast cancer.

Yogurt and cheese are rich in protein, but do they help aging muscles?

In a cross-sectional analysis of 6,790 adults aged 50 and older across two Irish cohorts, researchers found no consistent association between fermented dairy consumption and muscle strength, physical function, or frailty after accounting for lifestyle and socioeconomic factors. Although one analysis linked higher fermented dairy intake to greater odds of low grip strength, other findings did not support this association, and the researchers emphasized the need for further studies to establish whether fermented dairy influences healthy muscle aging.

‘Forever chemicals’ linked to slightly lower muscle mass in middle-aged women

A study of 551 middle-aged women found that higher blood concentrations of certain PFAS chemicals were associated with slightly lower muscle mass, particularly when researchers examined multiple chemicals together. However, these associations did not correspond to poorer muscle function, and the largely cross-sectional findings could not establish whether PFAS exposure contributes to muscle loss.

Exercise benefits mental health, so why is the genetic evidence so mixed?

A systematic review of 61 Mendelian randomization studies found limited and inconsistent genetic evidence that general physical activity causally improves mental health or cognitive outcomes; 30 studies reported only null or directionally opposite findings. More consistent evidence emerged for aerobic exercise and reduced depression risk, and for physical fitness traits, particularly muscle strength and muscle mass, in relation to better mental and cognitive health, although methodological limitations prevent definitive causal conclusions.

The way food feels in your mouth could change how much you eat

A scientific review examines how food texture and mouthfeel interact with oral sensory receptors, saliva, and brain pathways to influence food preferences, eating speed, appetite, and fullness. The authors suggest that understanding these mechanisms could help develop healthier, more satisfying foods, although their long-term effects on metabolic health require further investigation.

Exercise benefits people with chronic disease, but does the type matter?

A meta-analysis of 48 studies found that physical activity improved several chronic disease-related health indicators, particularly blood pressure, heart rate, and cardiorespiratory fitness, with significant benefits among people with hypertension and diabetes. Aerobic exercise had the strongest statistical evidence in the primary analysis, but no exercise type proved superior, and substantial variation between studies limited the certainty of the findings.

Ice massage, massage guns or rest? Runners tried three ways to recover

In a randomized trial of 80 recreational runners, repeated ice massage, percussive massage, and combined treatment improved reactive strength, reduced muscle soreness, and produced greater reductions in calf and Achilles tendon stiffness over 72 hours than passive rest. Combined treatment produced the largest improvement in reactive strength, although its advantage over individual treatments was based on exploratory comparisons, and none of the interventions showed a sustained benefit for the biochemical marker LDH.

Prenatal cannabis use disorder linked to higher postpartum psychiatric emergency visits

Women diagnosed with cannabis use disorder during pregnancy were more likely to end up in an emergency room for a psychiatric problem in the year after giving birth, according to a study of more than 2 million California deliveries.
