This meta-analysis of prospective cohort studies suggests that ED significantly increases the risk of CVD, coronary heart disease, stroke, and all-cause mortality, and the increase is probably independent of conventional cardiovascular risk factors.

Objectives Determine the impact of an 8-week mindfulness meditation program on disability, psychological function, and pain severity in community-dwelling older adults with chronic low back pain, and to test the education control program for feasibility. Design Randomized controlled trial. Participants Forty community-dwelling older adults with moderate low back pain or greater for at least the previous 3 months. Intervention Participants were randomized to an 8-week meditation program or an 8-week education control program. Outcome Measures Disability, psychological function, and pain severity were assessed. The same measures were obtained for both groups at baseline, at the end of the program, and 4 months after program completion. Results Sixteen participants (80%) completed the meditation program and 19 (95%) completed the education program. Both the meditation and control group improved on measures of disability, pain, and psychological function, both at program completion and 4-month follow-up. The differences between the two groups did not reach statistical significance. The meditation group practiced mindfulness meditation a mean of 5 days/week (range 1–7) and mean of 31 minutes/session (range 22–48). At 4 months follow-up 14/16 (88%) participants continued to meditate. Conclusion Both the intervention group and the education control group improved on outcome measures suggesting both programs had a beneficial effect. Participants continued to meditate on 4-month follow-up. The control program was feasible but not inert. Piloting the control program in mind–body research can inform the design of larger clinical trials.

Primary Sjögren's syndrome is one of the most common autoimmune diseases. So far, genetic studies of Sjögren's syndrome have relied mostly on candidate gene approaches. To identify new genetic susceptibility loci for primary Sjögren's syndrome, we performed a three-stage genome-wide association study in Han Chinese. In the discovery stage, we analyzed 556,134 autosomal SNPs in 542 cases and 1,050 controls. We then validated promising associations in 2 replication stages comprising 1,303 cases and 2,727 controls. The combined analysis identified GTF2I at 7q11.23 (rs117026326: Pcombined = 1.31 × 10(-53), combined odds ratio (ORcombined) = 2.20) as a new susceptibility locus for primary Sjögren's syndrome. Our analysis also confirmed previously reported associations in Europeans in the regions of STAT4, TNFAIP3 and the major histocompatibility complex (MHC). Fine mapping of the region around GTF2I showed that rs117026326 in GTF2I had the most significant association, with associated SNPs extending from GTF2I to GTF2IRD1-GTF2I.

BackgroundA number of case-control studies were conducted to investigate the association of common type 2 diabetes (T2D) risk gene polymorphisms with gestational diabetes mellitus (GDM). However, these studies have yielded contradictory results. We therefore performed a meta-analysis to derive a more precise estimation of the association between these polymorphisms and GDM, hence achieve a better understanding to the relationship between T2D and GDM.MethodsPubMed, EMBASE, ISI web of science and the Chinese National Knowledge Infrastructure databases were systematically searched to identify relevant studies. Data were abstracted independently by two reviewers. A meta-analysis was performed to examine the association between 9 polymorphisms from 8 genes and susceptibility to GDM. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated. Heterogeneity among articles and their publication bias were also tested.ResultsWe identified 22 eligible studies including a total of 10,336 GDM cases and 17,445 controls. We found 8 genetic polymorphisms were significantly associated with GDM in a random-effects meta-analysis. These polymorphisms were in or near the following genes: TCF7L2 (rs7903146), MTNR1B (rs10830963), IGF2BP2 (rs4402960), KCNJ11 (rs5219), CDKAL1 (rs7754840), KCNQ1 (rs2237892 and rs2237895) and GCK (rs4607517); while no association was found for PPARG with GDM risk. Similar results were also observed under dominant genetic model for these polymorphisms.ConclusionsThis meta-analysis found 8 genetic variants associated with GDM. The relative contribution and relevance of the identified genes in the pathogenesis of GDM should be the focus of future studies.

BackgroundAlthough it is known that Anderson-Fabry Disease (AFD) can mimic the morphologic manifestations of hypertrophic cardiomyopathy (HCM) on echocardiography, there is a lack of cardiovascular magnetic resonance (CMR) literature on this. There is limited information in the published literature on the distribution of myocardial fibrosis in patients with AFD, with scar reported principally in the basal inferolateral midwall.MethodsAll patients with confirmed AFD undergoing CMR at our center were included. Left ventricular (LV) volumes, wall thicknesses and scar were analyzed offline. Patients were categorized into 4 groups: 1) no wall thickening; 2) concentric hypertrophy; 3) asymmetric septal hypertrophy (ASH); and 4) apical hypertrophy. Charts were reviewed for clinical information.ResultsThirty-nine patients were included (20 males [51 %], median age 45.2 years [range 22.3–64.4]). Almost half (17/39) had concentric wall thickening. Almost half (17/39) had pathologic LV scar; three quarters of these (13/17) had typical inferolateral midwall scar. A quarter (9/39) had both concentric wall thickening and typical inferolateral scar. A subgroup with ASH and apical hypertrophy (n = 5) had greater maximum wall thickness, total LV scar, apical scar and mid-ventricular scar than those with concentric hypertrophy (n = 17, p < 0.05). Patients with elevated LVMI had more overall arrhythmia (p = 0.007) more ventricular arrhythmia (p = 0.007) and sustained ventricular tachycardia (p = 0.008).ConclusionsConcentric thickening and inferolateral mid-myocardial scar are the most common manifestations of AFD, but the spectrum includes cases morphologically identical to apical and ASH subtypes of HCM and these have more apical and mid-ventricular LV scar. Significant LVH is associated with ventricular arrhythmia.Electronic supplementary materialThe online version of this article (doi:10.1186/s12968-016-0233-6) contains supplementary material, which is available to authorized users.
