Background: Vitamin D may protect against respiratory virus infections, but any association with herpesviruses is unclear. Methods: We undertook a systematic review of vitamin D deficiency or supplementation and the risk of 8 human herpesviruses. Six databases and 4 gray literature databases w...

Objective: To compare the effects of food and antacids on the bioavailability of first-line anti-tuberculosis drugs. Method: Systematic search of electronic databases PubMed (January 1950-May 2009), and the Cochrane Library database (January 1974-May 2009), including the Cochrane Centre regist...

Chronic kidney disease (CKD) is cumulative worldwide and an increasing public health issue. Aside from the widely known protein restriction and medical therapy, less evident is the renal protection of nutrition supplements in CKD patients. This systematic review (SR), using a Grading of Recommend...

Background: Omega-3 (or n-3) polyunsaturated fatty acids (PUFAs) are promising antidepressant treatments for perinatal depression (PND) because of supporting evidence from clinical trials, the advantage in safety, and their anti-inflammatory and neuroplastic effects. Although several observationa...

Background and aims: We evaluated the efficacy and safety of probiotics for prevention of chemoradiotherapy-induced diarrhea in patients with abdominal or pelvic cancer. Methods: We searched the Cochrane Library, PubMed, EMBASE, Web of Science, Chinese National Knowledge Infrastructure (CNKI),...

BACKGROUND: Nutrients related to serum vitamin D level were previously shown to be significantly associated with the risk of many chronic diseases. This study aimed to assess potential relationships between serum vitamin D level and otitis media (OM) risk. METHODS: PubMed, EMBASE, and Cochrane Li...

BACKGROUND: Cardiac arrhythmias are associated with poorer outcomes in patients with heart failure (HF), diabetes mellitus (DM), and chronic kidney disease (CKD). Previous studies have shown inconsistent conclusions regarding the association between sodium-glucose cotransporter 2 inhibitors (SGLT...

OBJECTIVE: To investigate the association of vitamin D receptor (VDR) gene polymorphisms with OA susceptibility. METHODS: Meta-analyses were performed using allelic contrast, contrast of homozygotes, and recessive and dominant models to clarify the association between OA and VDR ApaI, BsmI, TaqI ...

Objective: Genetic variants of vitamin D receptor (VDR) were implicated in urolithiasis susceptibility in several case-control studies. However, these studies so far have provided conflicting results. In order to investigate the potential relationship, a meta-analysis was conducted. Methods: E...
