How bone marrow fat drives immune suppression and bone loss in obesity

Editorial Office of West China School of Stomatology, Sichuan University
Peer-Reviewed Publication

Obesity alters bone health not only through increased body weight but also by reshaping the bone marrow environment. Researchers show that expansion of bone marrow fat promotes immunosuppressive PD-L1 signaling, which enhances osteoclast formation and accelerates bone loss. By reducing bone marrow fat in mice, they reduced immune suppression and improved bone structure. These findings uncover a new mechanism linking metabolism, immunity, and skeletal health, offering potential therapeutic targets for obesity-related bone disorders.

Heatwaves and coldwaves are increasing cardiovascular events

European Society of Cardiology
Reports and Proceedings

Heatwaves and coldwaves are associated with increases in major cardiovascular events that are exacerbated by air pollution.¹ Concerning results on the adverse impact of climate change and pollution on cardiovascular risk were presented today^1,2 at ESC Preventive Cardiology 2026, the annual congress of the European Association of Preventive Cardiology (EAPC), a branch of the European Society of Cardiology (ESC).

Tire and rubber chemicals leave decades-long contamination record in Lake sediments

KeAi Communications Co., Ltd.
Peer-Reviewed Publication

Researchers analyzed 17 tire- and rubber-related chemicals in Lake Sihwa sediments and found the highest concentrations in creeks that discharge into the lake. Sediment cores showed that contamination pattern shifted over decades alongside rubber industry growth and later pollution-control measures. The study is the first to provide a historical baseline for tracking tire- and rubber-related contamination in a heavily industrialized coastal ecosystem.

Not everyone benefits: diabetes risk persists despite long-term weight loss

Deutsches Zentrum fuer Diabetesforschung DZD
Peer-Reviewed Publication

A healthy diet, weight loss, and increased physical activity can effectively prevent type 2 diabetes. However, not all individuals at elevated diabetes risk benefit equally from lifestyle interventions. People classified in Tübingen’s type 2 diabetes risk cluster 5 show rising blood glucose levels, the strongest decline in insulin secretion, and a persistently high risk of diabetes — even after years of stable and substantial weight loss. This is reported by researchers from the German Center for Diabetes Research (DZD), the University Hospital Tübingen and Helmholtz Munich in the scientific journal ‘Diabetes’.

Building everyday behavioral skills in early childhood could shield young brains from prenatal stress

The Graduate Center, CUNY
Peer-Reviewed Publication

Researchers from the City University of New York (CUNY) Graduate Center and Queens College suggest that building strong adaptive skills in early childhood may serve as a buffer against the detrimental effects of prenatal stress on a child’s developing brain.

Autism diagnosis by primary care providers: geographic variation among Medicaid-enrolled children in 29 states

Pediatric Academic Societies
Reports and Proceedings

A new study examined geographic patterns in autism diagnosis by primary care providers among Medicaid-enrolled children in 29 states. The study found that Nevada, South Carolina and Connecticut had the highest rates of autism diagnosis by primary care providers. Findings from the study will be presented at the Pediatric Academic Societies (PAS) 2026 Meeting, taking place April 24-27 in Boston. This study is part of a larger research project, Addressing Structural Disparities in Autism Spectrum Disorder through Analysis of Secondary Data (ASD3), which is funded by the National Institutes of Health.

New study examines measles vaccination coverage after a postelimination outbreak

Pediatric Academic Societies
Reports and Proceedings

A new study examined measles vaccination coverage following a large postelimination outbreak, primarily affecting unvaccinated children. Findings from the study will be presented during the Pediatric Academic Societies (PAS) 2026 Meeting, taking place April 24-27 in Boston.

New study examines impact of pediatric influenza vaccination rates on U.S. healthcare resource utilization

Pediatric Academic Societies
Reports and Proceedings

Achieving the Healthy People 2030 target of 70% immunization could substantially reduce the burden of influenza-related outpatient visits, hospitalizations, and deaths, while easing pressure on pediatric healthcare infrastructure and improving system resilience, according to a new study. The study aimed to quantify the impact of low influenza vaccination rates among children (ages 6 months to 17 years) on U.S. healthcare resources. Findings from the research will be presented at the Pediatric Academic Societies (PAS) 2026 Meeting, taking place April 24-27 in Boston.
