= 0, respectively). Meta-analysis, inclusive of all 10 cross-sectional studies with binary ORs, supported this finding. There was also some evidence that adults with current asthma and ever asthma (6 studies with categorical ORs) were less likely to exercise moderately and vigorously, but these meta-analyses were limited by high heterogeneity. No synthesis of the studies considering asthma control was possible.

Adults with current or ever asthma had lower levels of total, moderate and vigorous physical activity than those without asthma and may be missing out on the health benefits of being physically active. The association between asthma control and physical activity warrants further investigation.

In humans, cSVD such as cerebral amyloid angiopathy (CAA) often coexists with Alzheimer's disease imposing a significant impediment for characterizing their distinct effects on WM. Here we studied the burden of age-related CAA pathology on WM disease in a novel transgenic rat model of CAA type 1 (rTg-DI). A cohort of rTg-DI and wild-type rats was scanned longitudinally using MRI for characterization of morphometry, cerebral microbleeds (CMB) and WM integrity. In rTg-DI rats, a distinct pattern of WM loss was observed at 9 M and 11 M. MRI also revealed manifestation of small CMB in thalamus at 6 M, which preceded WM loss and progressively enlarged until the moribund disease stage. Histology revealed myelin loss in the corpus callosum and thalamic CMB in all rTg-DI rats, the latter of which manifested in close proximity to occluded and calcified microvessels. The quantitation of CAA load in rTg-DI rats revealed that the most extensive microvascular Aβ deposition occurred in the thalamus. For the first time using in vivo MRI, we show that CAA type 1 pathology alone is associated with a distinct pattern of WM loss.With the introduction of the anterior locking plate in the early part of this century, there was a large change in how distal radial fractures were treated. Early articles about the techniques reported tendon ruptures occurring in as many as 10%, although studies from our unit reported rates closer to 2%. Subsequent refinements in surgical technique and improvements in plate design have been made with the aim of reducing the number of ruptures. Despite this, the original articles and their rates continue to be quoted. In this retrospective study of 798 cases treated with anterior locking plates, tendon ruptures have been significantly reduced and are now as low as 0.5%. Contributing factors leading to this improvement are identified and discussed.Level of evidence III.To investigate the influence of vitamin D status on in vitro fertilisation (IVF) results, a meta-analysis of 15 cohort studies of 3711 women undergoing IVF was performed. Women were classified into three groups according their vitamin D levels (≥30 ng/mL considered replete/sufficient; 21-29 ng/mL insufficient and less then 20 ng/mL deficient). Three different meta-analyses were performed (i) sufficient vs deficient; (ii) sufficient vs 'insufficient + deficient'; (iii) 'sufficient + insufficient' vs deficient. Comparing IVF outcomes in sufficient versus deficient groups (considering autologous and donor oocyte cycles together), we found women with sufficient vitamin D had significantly higher biochemical pregnancy (OR = 1.43 [1.06-1.95]), ongoing pregnancy (OR = 1.29 [1.02-1.64]), and live birth (OR = 1.74 [1.31-2.31]) rates, with a non-significant trend to a higher clinical pregnancy rate (OR = 1.31 [0.94-1.82]), whereas implantation and miscarriage rates were similar. When the meta-analysis was restricted to autologous oocytes, the parameters which had been significant in the joint analysis remained significant, and differences in implantation (OR = 1.64, [1.17-2.29]) and clinical pregnancy (OR = 1.47 [1.2-1.69]) rates became significant. No significant differences were found when considering only cycles with donor oocytes. The sufficient + insufficient vs deficient and sufficient vs 'insufficient + deficient' comparisons identified significant differences in live birth rate. The meta-analysis shows that sufficient vitamin D status is associated with better outcomes in IVF. Nonetheless, there are many demographic, geographic and clinical parameters that may be related to vitamin D status that need to be ascertained before concluding that the better results are due to the higher levels of vitamin D.

Duchenne muscular dystrophy (DMD) is currently the most commonly diagnosed form of muscular dystrophy due to mutations in the dystrophin gene. However, its pathological process remains unknown and there is a lack of specific molecular biomarkers. The aim of our study is to explore key regulatory connections underlying the progression of DMD.

The gene expression profile dataset GSE38417 of DMD was obtained from the Gene Expression Omnibus (GEO) database. The differentially expressed genes (DEGs) between DMD patients and healthy controls were screened using geo2R, followed by Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO) pathway enrichment analyses. Then a protein-protein interaction (PPI) network and sub-network of modules were constructed. To investigate the regulatory network underlying DMD, a global triple network including miRNAs, mRNAs and transcription factors (TFs) was constructed.

A total of 1811 DEGs were found between the DMD and control groups, among which HERC5, SKP2 and FBXW5 were defined as hub genes with a degree of connectivity >35 in the PPI network. selleck chemical Furthermore, the five TFs ZNF362, ATAT1, SPI1, TCF12 and ABCF2, as well as the eight miRNAs miR-124a, miR-200b/200c/429, miR-19a/b, miR-23a/b, miR-182, miR-144, miR-498 and miR-18a/b were identified as playing crucial roles in the molecular pathogenesis of DMD.

This paper provides a comprehensive perspective on the miRNA-TF-mRNA co-regulatory network underlying DMD, although the bioinformatic findings need further validation in future studies.
