Low vitamin D at ICU admission is associated with cancer, infections, acute respiratory insufficiency, and liver failure.

Nutrition (Burbank, Los Angeles County, Calif.)
OBJECTIVES: Vitamin D deficiency may be associated with comorbidities and poor prognosis. However, this association in patients in the intensive care unit (ICU) has not been fully elucidated. The aim of this study was to investigate whether the serum...

Effect of combined vitamin D administration plus dietary intervention on oxidative stress markers in patients with metabolic syndrome: A pilot randomized study.

Clinical nutrition ESPEN
BACKGROUND: Metabolic syndrome (MetS) patients can have low 25-hydroxyvitamin D 25(OH)VitD levels, which may be associated with increased oxidative stress. There is little data on the effect of 25(OH)VitD administration plus dietary intervention on o...

The role of vitamin D in the human body with a special emphasis on dental issues: Literature review.

Dental and medical problems
The aim of the study was to review the current literature on the role of vitamin D in dentistry. The term vitamin D is defined as a group of compounds which are cholesterol derivatives with a similar chemical structure. It is produced in the human bo...

Vitamin D deficiency and high serum IL-6 concentration as risk factors for tubal factor infertility in Chinese women.

Nutrition (Burbank, Los Angeles County, Calif.)
OBJECTIVES: The aim of this study was to investigate the relationship between 25-hydroxyvitamin-D [25(OH)D] and female infertility and to further explore the role of inflammatory cytokines.

Vitamin D and obstructive sleep apnea: a systematic review and meta-analysis.

Machine learning approaches infer vitamin D signaling: Critical impact of vitamin D receptor binding within topologically associated domains.

The Journal of steroid biochemistry and molecular biology
The vitamin D-modulated transcriptome of highly responsive human cells, such as THP-1 monocytes, comprises more than 500 genes, half of which are primary targets. Recently, we proposed a chromatin model of vitamin D signaling demonstrating that nearl...
