Purpose: This study aimed to analyze the content and effectiveness of psychosocial support interventions for women with gestational diabetes mellitus (GDM). Methods: The following databases were searched with no limitation of the time period: Ovid-MEDLINE, Cochrane Library, Ovid-Embase, CINAHL, PsycINFO, NDSL, KoreaMed, RISS, and KISS. Two investigators independently reviewed and selected articles according to the predefined inclusion/exclusion criteria. ROB 2.0 and the RoBANS 2.0 checklist were used to evaluate study quality. Results: Based on the 14 selected studies, psychosocial support interventions were provided for the purpose of (1) informational support (including GDM and diabetes mellitus information; how to manage diet, exercise, stress, blood glucose, and weight; postpartum management; and prevention of type 2 diabetes mellitus); (2) self-management motivation (setting goals for diet and exercise management, glucose monitoring, and enhancing positive health behaviors); (3) relaxation (practicing breathing and/or meditation); and (4) emotional support (sharing opinions and support). Psychosocial supportive interventions to women with GDM lead to behavioral change, mostly in the form of self-care behavior; they also reduce depression, anxiety and stress, and have an impact on improving self-efficacy. These interventions contribute to lowering physiological parameters such as fasting plasma glucose, glycated hemoglobin, and 2-hour postprandial glucose levels. Conclusion: Psychosocial supportive interventions can indeed positively affect self-care behaviors, lifestyle changes, and physiological parameters in women with GDM. Nurses can play a pivotal role in integrative management and can streamline the care for women with GDM during pregnancy and following birth, especially through psychosocial support interventions.

Background and Aims: Recent meta-analysis of genome-wide association studies have identified over 241 inflammatory bowel disease susceptibility loci. However, the known variants only account for a fraction of inflammatory bowel disease heritability. To identify additional susceptibility loci, we performed a trans-ethnic meta-analysis as well as an Asian-specific meta-analysis, using all published Immunochip association results of inflammatory bowel disease. Methods: An inverse-variance fixed-effects meta-analysis was carried out across Korean and East Asian Immunochip datasets of 4156 cases and 4904 controls [Asian ancestry]. A trans-ethnic metaanalysis of inflammatory bowel disease was performed together with the European datasets of 38 155 cases and 48 485 controls genotyped on the immunochip using a Bayesian approach, Meta- Analysis of Trans-ethnic Association studies [MANTRA]. Results: We identified seven novel associations, including three novel susceptibility loci at MYO10- BASP1, PPP2R3C/KIAA0391/PSMA6/NFKB1A and LRRK1 as well as four novel secondary associations within previously known loci at NCF4, TSPAN32, CIITA and VANGL2. The new loci further implicate alterations in B cell biology in Crohn's disease pathogenesis. The effects of five loci were universal across European and Asian ancestries, whereas the NCF4 and CIITA loci showed significant heterogeneity between European and East Asian populations. In addition, 103 previously known IBD loci showed supporting evidence of association with nominal significance [p < 0.05] in Asians. Conclusions: Our findings of new loci not previously associated with IBD support the importance of studying inflammatory bowel disease genetics in diverse populations. [ABSTRACT FROM AUTHOR]

Background and Aims: Genome-wide association studies of inflammatory bowel disease identified > 200 susceptibility loci only in autosomes. This study aimed to identify inflammatory bowel disease susceptibility loci on the X chromosome. Methods: We performed an X chromosome-wide association study in Korean patients with inflammatory bowel disease. We analysed X chromosome data from our recent genome-wide association studies, including 1505 cases [922 Crohn's disease and 583 ulcerative colitis] and 4041 controls during the discovery phase, followed by replication in additional 1989 cases [993 Crohn's disease, 996 ulcerative colitis] and 3491 controls. Sex-related differential effects of single nucleotide polymorphisms on disease were also evaluated. Results: We confirmed a significant association of a previously reported inflammatory bowel disease susceptibility locus at chromosome Xq26.3 [CD40LG-ARHGEF6; odds ratio, 1.22; 95% confidence interval, 1.16-1.28; combined p = 3.79 × 10-15]. This locus accounted for 0.18% and 0.12% of genetic variance in Crohn's disease and ulcerative colitis, respectively, and increased the total autosomal chromosome genetic variance from 6.65% to 6.83% and from 5.47% to 5.59% for Crohn's disease and ulcerative colitis risk, respectively, in the Korean population. Sex-stratified analyses did not reveal sex-related differences in effect sizes. Conclusions: We confirmed the association of rs2427870 at the CD40LG-ARHGEF6 locus with an inflammatory bowel disease through an X chromosome-wide association study in a Korean population. Our data suggest that the CD40LG-ARHGEF6 locus on the X chromosome might play a role in inflammatory bowel disease pathogenesis in the Korean population. [ABSTRACT FROM AUTHOR]
