Evidence on the association between long-term exposure to ambient air pollution and serum glycosylated hemoglobin A1c (HbA1c) is limited and inconclusive. In addition, whether vitamin D can modify the association between air pollution exposure and glucose metabolism has not been previously investigated. We aimed to evaluate the effects of various air pollutants on serum HbA1c levels in patients with hypertension and, further, to explore the modification effect of individual serum vitamin D levels. ⋯ Long-term exposures to ambient air pollutants were associated with higher levels of HbA1c in a dose-response fashion in a large UK cohort. Serum vitamin D status significantly modified these associations, and high serum vitamin D levels may attenuate the relationships between air pollution exposures and HbA1c levels.

Zinc and copper are trace elements, but their reference values during the neonatal and infant periods are not clear. We aimed to determine the trend of serum zinc levels in infants admitted to the neonatal intensive care unit and compare serum zinc and serum copper levels at admission between small-for-gestational-age (SGA) and non-SGA infants. ⋯ All of the infants admitted to the neonatal intensive care unit at ≤34 wk of gestation were zinc deficient by 2 mo of age, suggesting the need for enteral zinc administration. Serum copper was higher in SGA infants than in non-SGA infants on admission, but further studies are needed to determine whether excess copper affects development.

The prevention of children being overweight/obese is of utmost importance. Parental characteristics play a pivotal role in shaping offspring weight status. This study aimed to examine associations between parental obesity and children's overweight/obesity status, and whether other parental type 2 diabetes (T2D) risk factors can predict children's obesity status. ⋯ Among parental risk factors for T2D, maternal/parental overweight/obesity status, central obesity, and high FINDRISC score were the main predictors of childhood overweight/obesity status, with BMI the most accurate. Maternal or paternal BMI is simple to use, and might be useful for the early identification of children at risk of being overweight/obese rather than other T2D factors.

This study aimed to examine the association between improvement in sarcopenia and the recovery of urinary and defecatory independence in patients undergoing convalescent rehabilitation. ⋯ Of the patients recruited, 151 were diagnosed with sarcopenia at baseline, of whom patients dependent in urination (109 patients) and defecation (102 patients) were included in the analysis. The multivariate analysis showed that improvement in sarcopenia (odds ratio [OR]: 3.28; 95% confidence interval [CI],1.01-10.70; P = 0.048) and HGS (OR: 6.25; 95% CI, 1.45-26.90; P = 0.014) were independently associated with FIM-Bladder at the time of discharge. Improvement in HGS (OR: 4.33; 95% CI, 0.99-18.90; P = 0.048) was independently associated with FIM-Bowel at the time of discharge CONCLUSIONS: Improvement in sarcopenia and muscle strength during hospitalization may have a positive effect on urinary independence in stroke patients undergoing convalescent rehabilitation, and improvement in muscle strength may have a positive effect on defecation independence. Multidisciplinary sarcopenia treatment should be implemented in addition to conventional rehabilitation for these patients.

Endocrine disorders in women of childbearing age, including polycystic ovarian syndrome (PCOS), have been linked to skeletal muscle insulin resistance with multiple post-receptor intracellular defects, disrupting metabolic flexibility. Short-chain fatty acids, such as acetate have been suggested as a metabolic modulator. However, the effects of acetate on aberrant metabolic switch in skeletal muscle of individuals with PCOS are unknown. This study therefore hypothesized that acetate would circumvent impaired metabolic switch in the skeletal muscle of a letrozole-induced PCOS rat model, probably by suppression of PDK4/NLRP3. ⋯ The present results demonstrate aberrant metabolic switch in the skeletal muscle of PCOS animals, which is accompanied by excessive inflammation, oxidative stress and elevated levels of histone deacetylase and PDK4. The results suggested that histone deacetylase inhibitor, acetate circumvents impaired metabolic switch in the skeletal muscle of PCOS rats by suppression of PDK4/NLRP3 inflammasome.
