BACKGROUND Vitamin D insufficiency is widespread in China. Various factors influence vitamin D level in the body. The present study investigated vitamin D status of residents in Jinzhong city, China, and analyzed the influence of gender on vitamin D status. MATERIAL AND METHODS In this cross-sectional study, 302 participants (176 men and 126 women) were recruited. Anthropometric data (body circumferences and height, weight) were collected, and serum vitamin D concentration was tested. RESULTS Inadequate levels of vitamin D were found in 69% of men and 75% of women. Women's 25(OH)D level (38.40±12.37 nmol/l) was substantially lower than that of the men (43.49±14.78 nmol/l) (p<0.01). The young women group had the lowest vitamin D level, which was even significantly below that of the elderly women group. Multiple linear regression analysis showed gender was significantly associated with vitamin D status (p<0.01). CONCLUSIONS Vitamin D deficiency is common in residents of Jinzhong during the winter. Compared to men, women are more prone to have inadequate vitamin D levels.

Introduction: Population risk for neural tube defects (NTDs) can be determined using red blood cell (RBC) folate. However, a paucity of biomarker and surveillance data among non-lactating, non-pregnant women of reproductive age (NPWRA) from Africa limits accurate assessment. Our study assessed folate and vitamin B12 status among non-lactating NPWRA and predicted population risk of NTDs in Tanzania.

Lessons Learned: Intravenous paricalcitol did not improve the efficacy of pembrolizumab, likely related to the short half-life.
Background: Immunotherapy has limited benefit in the treatment of advanced pancreatic cancer with the tumor microenvironment playing a key role in immune resistance. In preclinical studies, vitamin D receptor (VDR) agonists have been shown to sensitize pancreatic tumors to PD-1 blockade.

There is little research on anemia and vitamin D deficiency in HIV-exposed uninfected (HEU) children. This study was aimed to describe and compare the prevalence of anemia and vitamin D inadequacy in HEU children and HIV-unexposed uninfected (HUU) children, and to examine the associations of HIV exposure with anemia and vitamin D inadequacy. This was a hospital-based descriptive cross-sectional study nested within the Prevention of Mother-to-Child Transmission (PMTCT) of HIV program in Hunan Province during July and September 2022.
