AI Article Synopsis
- The polymorphism rs10830963 C>G in the melatonin receptor 1B gene has been linked to a higher risk of gestational diabetes mellitus (GDM), as shown in a meta-analysis of 14 studies with over 5,000 GDM patients.
- Results revealed that carrying the G allele increases GDM risk significantly, with various odds ratios presented for different genetic comparisons.
- The findings were consistent across ethnic groups, and further studies are suggested to investigate the underlying mechanisms of this association.
Article Abstract
The melatonin receptor 1B (MTNR1B) polymorphism rs10830963 C>G has been reported to be associated with the risk of gestational diabetes mellitus (GDM) with inconsistent results. To clarify the effect of the polymorphism on the risk of GDM, a meta-analysis therefore was performed. Pooled OR with its corresponding 95%CI was used to estimate the strength of the association. Totally 14 eligible studies with a number of 5033 GDM patients and 5614 controls were included in this meta-analysis. Results indicated that the variant G allele was significantly associated with an increased GDM risk (CG vs. CC: OR = 1.25, 95% CI = 1.11-1.40, P < 0.001; GG vs. CC: OR = 1.78, 95% CI = 1.45-2.19, P < 0.001; G vs. C: OR = 1.33, 95% CI = 1.21-1.47, P < 0.001). In the stratified analysis by ethnicity, similar results were found in Asians (CG vs. CC: OR = 1.15, 95%CI = 1.02-1.28, P = 0.020; GG vs. CC: OR = 1.52, 95% CI = 1.23-1.89, P < 0.001; G vs. C: OR = 1.23, 95% CI = 1.10-1.37, P < 0.001) and in Caucasians (CG vs. CC: OR = 1.40, 95% CI = 1.16-1.70, P < 0.001; GG vs. CC: OR = 2.21, 95% CI = 1.54-3.17, P < 0.001; G vs. C: OR = 1.47, 95% CI = 1.24-1.73, P < 0.001). FPRP and TSA analyses confirmed findings support that the rs10830963 G allele increases the risk of GDM, and further functional experimental studies are warranted to explore and clarify the potential mechanism.

Article Synopsis
- * Findings reveal that individuals carrying the rs10830963-G and rs1387153-T alleles have a significantly higher risk of IS, with each additional allele increasing risk by 36% and 32% respectively.
- * Importantly, the study shows that adopting a healthier lifestyle can reduce the impact of these genetic risk factors, suggesting that a better lifestyle score leads to a decreased association between the gene variants and IS risk.

This study explores the relationship between the light features of the Arctic spring equinox and circadian rhythms, sleep and metabolic health. Residents (N = 62) provided week-long actigraphy measures, including light exposure, which were related to body mass index (BMI), leptin and cortisol. Lower wrist temperature (wT) and higher evening blue light exposure (BLE), expressed as a novel index, the nocturnal excess index (NEI), were the most sensitive actigraphy measures associated with BMI.
