Obesity disrupts ILC2 metabolism through increased fatty acid uptake

A group of innate immune cells, known as group 2 lymphoid cells (ILC2), are essential for maintaining a stable metabolism in adipose tissue. Obesity significantly impairs the number and function of ILC2 cells, leading to the progression of metabolism-related inflammation.

What links smoking, body fat, mental health, genes, and heart risk? Inflammation may be part of the answer

In a large UK Biobank study, higher levels of the chronic inflammation marker GlycA were associated with smaller heart chambers, thicker heart walls, impaired diastolic function, reduced stroke volume, and a 43% higher risk of major adverse cardiovascular events in the highest versus lowest GlycA group. Genetic susceptibility also modified the associations between environmental exposures, inflammation, and cardiovascular risk, while inflammatory proteins in the IL-1, TNF, and IL-6 pathways statistically mediated several of these associations.

Cancer incidence rises faster among people with type 2 diabetes

A nationwide study being presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) has found that people with type 2 diabetes (T2D) have a higher risk of developing cancer, with cancer incidence rising more among people with T2D than those without diabetes over the past 25 years, largely driven by obesity-related cancers.

Higher BMI linked to brain differences in preschool children

Children as young as 4 with a higher body mass index (BMI) showed differences in several brain regions involved in reward, taste and hunger, according to a new study from Florida International University.

Childhood trauma linked to risky health behaviors in late adolescence

Experiencing childhood trauma appears to increase a young person's likelihood of smoking, substance use and developing unhealthy eating habits by contributing to behavioral problems during adolescence, such as impulsivity and poor self-control.

New roadmap integrates arts into global health and wellbeing

Researchers have developed a roadmap for integrating the arts across health and wellbeing systems globally, from population health and prevention to community pathways and clinical care.

Regular exercisers show distinct metabolic and immune signatures in blood

Researchers compared blood samples from 40 regular exercisers and 46 sedentary adults and found differences in metabolites, blood chemistry, and immune cell gene activity. The patterns suggested greater fatty acid use and altered immune signaling among exercisers, but the study could not establish that exercise caused these differences.

Sugary drinks stood out in this stomach cancer study, but diet drinks did not

In two large US prospective cohorts, consuming more than one sugar-sweetened beverage a day was associated with higher gastric cancer incidence compared with consuming less than one serving a month. Artificially sweetened beverages were not associated with gastric cancer incidence, and the authors called for further studies to confirm the findings and clarify possible biological mechanisms.

Type 1 diabetes runners can safely complete marathons with careful glucose management

New research to be presented at the Annual Meeting of the European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28th – Oct 2nd) shows, with the use of continuous glucose monitoring (CGM) devices people with type 1 diabetes can complete a marathon safely and achieve finishing times similar to runners without diabetes.

More physical activity linked to lower type 2 diabetes risk in adults

Better fitness was linked to healthier brain structure, but not better memory

Researchers studying 353 cognitively unimpaired adults aged 60 to 94 found that higher muscular capacity was associated with lower basal ganglia perivascular space volume, while greater aerobic fitness was associated with greater gray matter volume and medial temporal lobe thickness. Fitness was not directly associated with global cognition or episodic memory, and evidence for cognitive reserve was limited, although VO₂max explained additional variation in delayed verbal memory beyond tau burden.

Exercise-based cardiac rehabilitation offers lasting heart health benefits

Exercise-based cardiac rehabilitation reduces hospital admissions by a third and heart attack risk by more than a quarter, as well as remaining beneficial in the long term, a new Cochrane review finds.

Being active may not tell the whole story when it comes to weight gain

A five-year study of 2,606 young and early-midlife Finnish municipal employees examined how leisure-time physical activity and sedentary behavior were associated with gaining at least 10% of baseline body weight. About 24% of women and 12% of men experienced major weight gain, with the analysis pointing to the importance of considering activity and sedentary time together.

Fermented dairy was linked to lower mortality, but the pattern shifted at higher intakes

Analysis of 37,366 US adults found that fermented dairy consumption was associated with lower all-cause and cardiovascular mortality, with consumers showing adjusted hazards 18% and 20% lower, respectively, than non-consumers. Dose-response analyses indicated that the inverse association was concentrated at intakes below about 150 grams per day, while the observational study could not establish causality.

Finnish adults eat too little of some foods and too much of others, study finds

Analysis of dietary data from 1,655 Finnish adults found that usual food intake often differed substantially from the quantitative targets later set by the Nordic Nutrition Recommendations 2023. Plant-based foods were generally underconsumed, while red and processed meat and dairy intake frequently exceeded study targets, with adherence varying by sex, education, physical activity, age, and energy intake.

Exercise usually helps the brain. During a 15-day fast, the story was different

In a 28-day controlled study of 22 healthy adults, 15 days of complete fasting produced a glucose-to-ketone metabolic shift and selectively affected attention and implicit learning while time perception remained relatively stable. Moderate-intensity exercise during early fasting was associated with poorer performance on some learning measures, while fasting also increased sleepiness and reduced calmness at some time points.

Cardiovascular disease surpasses cancer as top killer of Hispanic populations in the U.S.

Cardiovascular disease has surpassed cancer as the leading cause of death among Hispanic adults in the U.S., driven by rising rates of obesity, diabetes, high blood pressure and other risk factors that often begin earlier in life for Hispanic people.

Study explains why Amazonian Indigenous populations show low dementia prevalence

In two Indigenous communities living pre-industrial lifestyles in the Bolivian Amazon, dementia is remarkably uncommon.

Finnish study finds working from home increases sedentary behavior

According to a Finnish study, people sleep slightly longer when they work from home. However, they also sit more and are less physically active than on days when they work in the office.

Coffee after colorectal cancer? Decaf and caffeine show different links with mortality

In a prospective analysis of 1,098 people with colorectal cancer, researchers found no significant association between total or caffeinated coffee intake and all-cause or colorectal cancer-specific mortality in the cohort overall. Decaffeinated coffee was associated with lower all-cause mortality, while the highest quartile of caffeine intake was associated with lower all-cause and colorectal cancer-specific mortality, although the observational study cannot establish causation.
