The global burden of chronic kidney disease in women and its metabolic–cardiovascular links

The global burden of chronic kidney disease in women has grown, with 359 million cases in 2021, driving increasing mortality rates and disability-adjusted life years. Postmenopausal women and women of reproductive age are particularly vulnerable to metabolic and behavioral drivers that can be modified to reduce risk.

Aging reprograms skin genetic activity and promotes inflammation

Aging reprograms skin genetic activity by increasing inflammatory gene expression in the epidermis, leading to a loss of skin function. This mechanism is mediated by the collaboration of two proteins, BMAL1 and YAP, which normally maintain skin homeostasis.

Do alumni relationships between judges and lawyers affect court rulings?

Research in Economic Inquiry reveals evidence of in-group bias in the judiciary, with sharing a law school with the presiding judge increasing a plaintiff's attorney's chance of winning damages by 2 percentage points. The effect is strongest when the judge is at least 10 years older than the lawyer, suggesting an age-dependent factor.

How do body mass index and waist circumference affect mortality in older adults?

A study of 6,905 US adults aged 65 or older found that higher body mass index (BMI) was associated with lower mortality risk, while higher waist circumference was linked to higher mortality risk. Considering both BMI and waist circumference together may improve mortality risk assessment and support informed clinical decision-making.
