The extent to which physical activity and psychological factors may affect the risk of diabetes mellitus among lean individuals remains unclear. This study aimed to investigate the associations of total physical activity (TPA) and psychological factors with lean type 2 diabetes mellitus (T2DM) risk. A prospective cohort study. The study population included 1,945 Korean adults who maintained a body mass index <23 kg/m. Baseline data on TPA and psychological factors were collected and T2DM incidence was assessed for 10 years. For analysis, a multivariable Cox proportional hazards regression model was used. TPA was inversely associated with T2DM risk and this association was more pronounced in participants who were depressed or distressed; the top TPA quartile exhibited significant reductions in T2DM risk of 66% (95% confidence interval [CI]: 0.15, 0.78) and 65% (95% CI: 0.14, 0.88) among participants who reported depressed mood and those who perceived high distress, respectively, compared with the bottom TPA quartile. The current study demonstrated the preventive effects of physical activity on T2DM in lean adults through its interaction with psychological factors.

Obesity is a chronic condition that causes significant morbidity and mortality in people in the United States and around the world. Traditional means of weight loss include diet, exercise, behavioral modifications, and surgery. New weight loss medications, glucagon-like peptide-1 receptor agonists, are revolutionizing the management of weight loss but have implications for fertility and pregnancy.

Purpose: Previous studies have described barriers to and facilitators of healthy eating and being physically active among patients with cancer, but few have done so in a safety-net community oncology setting.

Materials And Methods: To understand multiple perspectives on the factors that influence diet and exercise in patients with cancer treated in safety-net settings, we conducted semistructured interviews between June and November 2021 with patients and oncology clinic medical professionals at a safety-net hospital in Houston, TX.

Results: Thirty-one patients with cancer were interviewed, including 11 patients on active treatment and 20 survivors, as well as 21 care health care professionals.

Lysosomal dysfunction and inflammatory sterol metabolism in pulmonary arterial hypertension.

Vascular inflammation regulates endothelial pathophenotypes, particularly in pulmonary arterial hypertension (PAH). Dysregulated lysosomal activity and cholesterol metabolism activate pathogenic inflammation, but their relevance to PAH is unclear. Nuclear receptor coactivator 7 () deficiency in endothelium produced an oxysterol and bile acid signature through lysosomal dysregulation, promoting endothelial pathophenotypes.

Chirality, a pervasive form of symmetry, is intimately connected to the physical properties of solids, as well as the chemical and biological activity of molecular systems. However, inducing chirality in a nonchiral material is challenging because this requires that all mirrors and all roto-inversions be simultaneously broken. Here, we show that chirality of either handedness can be induced in the nonchiral piezoelectric material boron phosphate (BPO) by irradiation with terahertz pulses.
