Abstract
BACKGROUND Numerous studies have examined whether vitamin D is associated with gestational diabetes mellitus (GDM). Nevertheless, it is still challenging to determine the causality, due to a number of shortcomings in observational research and randomized controlled trials. OBJECTIVE Mendelian randomization (MR) with two samples was conducted to investigate the potential causative association between 25-hydroxyvitamin D (25(OH)D), vitamin D binding protein (VDBP) and GDM risk. METHODS Publicly accessible summary data from independent cohorts were used for two-sample MR. For 25(OH)D, we obtained data from UK Biobank, IEU and EBI, then performed a meta-analysis to enhance the statistical power (via METAL); for VDBP, data were obtained from the INTERVAL study; for GDM, data were obtained from FinnGen. The inverse variance weighted (IVW) approach was performed as the main analysis, together with several sensitivity analyses, such as MR-Egger, maximum likelihood, weighted median, and weighted mode. RESULTS The IVW results revealed a weak negative causal connection between 25(OH)D and GDM risk [OR (95% CI) = 0.71 (0.50, 0.99), p = 0.046]. However, the causal association was unstable according to sensitivity analyses, and Cochran's Q test revealed significant heterogeneity. After removing BMI-related IVs, the causal association between 25(OH)D and GDM disappeared [OR (95% CI) = 0.76 (0.55, 1.06), p = 0.101]. In addition, our study found no proof to support the assumption that VDBP level was related to GDM risk causally [OR (95% CI) = 0.98 (0.93, 1.03), p = 0.408]. CONCLUSIONS According to this study, a weak negative causal association between 25(OH)D and GDM risk was found, while we had little proof to support the link between VDBP and GDM. To further explore whether total or free 25(OH)D levels and GDM are causally related, GWAS data with an emphasis on women of reproductive age and other ethnic groups are required.

Abstract
Findings from observational studies have suggested a possible association between dietary inflammatory index (DII) and risk of gestational diabetes mellitus (GDM) and preeclampsia (PE). However, the results of these studies were inconclusive. A systematic review and meta-analysis was carried out to illuminate this association. Systematic literature search was conducted in PubMed, Web of Science, Cochrane Library, EMBASE, Scopus and other databases from inception until January 2023. The qualities of included studies were assessed using the Newcastle-Ottawa scale. Nine studies (seven cohort, two case-control) were included in the meta-analysis, including 11 423 participants from five different countries. The meta-analysis indicated that a 1-unit increase in the DII score, representing pro-inflammatory diet, was associated with 13 % higher risk of GDM (OR = 1·13; 95 % CI 1·02, 1·25, I2 = 68·4 %, P = 0·004) and 24 % higher risk of PE (OR = 1·24; 95 % CI 1·14, 1·35, I2 = 52·0 %, P = 0·125). Subgroup analysis found that this association was evident among studies with Chinese populations (OR = 1·16; 95 % CI 1·06, 1·28) and studies with mid pregnancy (OR = 1·20; 95 % CI 1·07, 1·34). The findings indicate that pro-inflammatory diet can increase the risk of GDM and PE. Considering some limitations in this study, more studies are needed to verify this association.

The effect of probiotic and synbiotic use on glycemic control in women with gestational diabetes: A systematic review and meta-analysis. Diabetes Res Clin Pract 2022; 194:110162. [PMID: 36403680 DOI: 10.1016/j.diabres.2022.110162] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 10/26/2022] [Accepted: 11/14/2022] [Indexed: 11/19/2022]
Abstract
AIMS To investigate the impact of probiotic/synbiotic use on glycemic control in women with gestational diabetes. METHODS We searched the PubMed, Medline, Scopus, ScienceDirect, Web of Science, Cochrane Central Register of Controlled Trials, Dergipark, and Council of Higher Education Thesis Center databases through March 2022. Screening was performed according to the population, intervention, comparison, outcome and study type. This systematic review and meta-analysis were performed in accordance with the Preferred Reporting Items for Systematic Review and meta-analyses (PRISMA-2020) statement. RESULTS Eight RCTs involving 551 patients were included in the meta-analysis. Probiotic use in women with gestational diabetes significantly decreased fasting blood glucose (mean difference: -1.43; 95 % CI: -2.78 to -0.09, p: 0.04) and serum insulin (mean difference: -3.66; 95 % CI: -5.04 to -2.27, p < 0.001). Moreover, the use of probiotics and synbiotics significantly reduced the HOMA-IR level compared to the control group (probiotic group: mean difference: -0.74; 95 % CI: -1.05 to -0.44, p < 0.001; synbiotic group: mean difference: -0.68; 95 % CI: -1.26 to -0.09, p: 0.02). CONCLUSIONS The use of probiotics in women with GDM reduced fasting plasma glucose, fasting serum insulin, and HOMA-IR levels. In addition, the use of synbiotics decreased HOMA-IR. Probiotic/synbiotic use is promising as a potential therapy to assist in glycemic control in gestational diabetes. Further high-quality studies are required to determine their safety.
