Sepsis is a lethal clinical condition with dysregulated cluster of differentiation (CD) 4+ T cells that leads to inflammation and multiorgan injury. Low vitamin D levels are commonly seen in patients with sepsis. Obesity is a state with oxidative stress and chronic inflammation. Both obesity and low vitamin D levels are associated with adverse outcomes in patients with sepsis. This study investigated the effects of calcitriol on CD4+ T-cell polarization and kidney injury during sepsis. ⋯ These findings suggest that intravenous calcitriol administration after sepsis modulates the homeostasis of CD4+ T-cell subpopulations associated with alleviating sepsis-induced kidney injury in obese mice.

The association between major dietary patterns and metabolic health status in adolescents has been understudied, especially in Middle Eastern populations. The aim of this study was to evaluate this association in overweight/obese adolescents. ⋯ We found an inverse association between the Mediterranean-like dietary pattern and odds of MUO in Iranian overweight/obese adolescents, whereas the Western dietary pattern was associated with an increased likelihood of being MUO. Further studies, with a prospective nature, are required to confirm these findings.

The regular consumption of whole grains is linked to a lower likelihood of developing metabolic disorders. We previously found that chronic supplementation with wheat alkylresorcinols (ARs) prevents obesity and its associated metabolic symptoms induced by a high-fat high-sucrose diet (HFHSD) in mice. The aim of this study was to examine the time-of-day-dependence of these effects in mice. ⋯ These findings suggested that ARs ameliorate feed efficiency by decreasing dietary lipid absorption more effectively at the time of activity onset than offset. Further studies are needed to elucidate the molecular mechanism of the time-of-day-dependent effects of ARs on diet-induced metabolic disorders.

The number of people aged ≥60 y is increasing worldwide, so establishing a relationship between lifestyle and health-associated factors, such as gut microbiota in an older population, is important. This study aimed to characterize the gut microbiota of a presenior population, and analyze the association between some bacteria and quality of life with the Short Form (SF) 36 questionnaire. ⋯ Quality of life may be associated with the relative abundance of certain bacteria, especially Actinobacteria and Peptostreptococcaceae, which may have a specific effect on certain markers and health care, which is important to improve quality of life in older populations.
