Background In traditional Chinese medicine, acupuncture has been used to treat angina due to coronary artery disease (CAD). The aim of this systematic review of the literature and meta-analysis was to identify published randomized controlled trials (RCTs) that quantified the effectiveness of adjunctive acupuncture treatment in patients with angina due to CAD who were also treated with Western or Chinese medicine. Material/Methods A systematic review of the literature included a search of the PubMed, Embase, Cochrane library, and China National Knowledge Infrastructure (CNKI) databases, from their inception to September 2018. Published findings from RCTs were included that investigated the effectiveness of acupuncture as an adjunctive treatment for angina due to CAD in combination with Western or traditional Chinese medicine. The odds ratio (OR) and 95% confidence interval (CI) were calculated using the random-effects model to determine the outcomes of markedly and moderately effective rates for the use of acupuncture. Results Twenty-four published RCTs were identified that included 1,916 patients with CAD. Patients who received adjunctive acupuncture treatment had a significantly increased markedly effective rate. However, the moderately effective rate between adjunctive acupuncture combined with standard treatment for angina and standard treatment alone was not statistically significant. Sensitivity analysis showed that the pooled results for the markedly and moderately effective rates were robust. Subgroup analysis in most subsets supported the main findings. Conclusions Meta-analysis supported a positive treatment effect for the use of acupuncture when used as adjunctive therapy in patients with angina due to CAD.

Recent compelling results indicate possible links between neurotransmitters, intestinal mucosal IgA + B cell responses, and immunoglobulin A nephropathy (IgAN) pathogenesis. Here, we demonstrated that γ-amino butyric acid (GABA) transporter-2 (GAT-2) deficiency induces intestinal germinal center (GC) B cell differentiation and worsens the symptoms of IgAN in a mouse model. Mechanistically, GAT-2 deficiency enhances GC B cell differentiation through activation of GABA–mammalian target of rapamycin complex 1 (mTORC1) signaling. In addition, IgAN patients have lower GAT-2 expression but higher activation of mTORC1 in blood B cells, and both are correlated with kidney function in IgAN patients. Collectively, this study describes GABA signaling–mediated intestinal mucosal immunity as a previously unstudied pathogenesis mechanism of IgAN and challenges the current paradigms of IgAN.

Background Kangaroo mother care (KMC) is an evidence-based intervention that reduces morbidity and mortality in preterm infants. However, it has not yet been fully integrated into health systems around the world. The aim of this study is to provide a cogent summary of the evidence base of the key barriers and facilitators to implementing KMC. Methods An umbrella review of existing reviews on KMC was adopted to identify systematic and scoping reviews that analysed data from primary studies. Electronic English databases, including PubMed, Embase, CINAHL and Cochrane Library, and three Chinese databases were searched from inception to 1 July 2022. Studies were included if they performed a review of barriers and facilitators to KMC. Quality assessment of the retrieved reviews was performed by at least two reviewers independently using the Joanna Briggs Institute (JBI) critical appraisal checklist and risk of bias was assessed with the Risk of Bias Assessment Tool for Systematic Reviews (ROBIS) tool. This umbrella review protocol was documented in the PROSPERO registry (CRD42022327994). Results We generated 531 studies, and after the removal of duplicates and ineligible studies, six eligible reviews were included in the analysis. The five themes identified were environmental factors, professional factors, parent/family factors, access factors, and cultural factors, and the factors under each theme were divided into barriers or facilitators depending on the specific features of a given scenario. Conclusions Support from facility management and leadership and well-trained medical staff are of great significance to the successful integration of KMC into daily medical practice, while the parents of preterm infants and other family members should be educated and encouraged in KMC practice. Further research is needed to propose strategies and develop models for implementing KMC.

The advantages of urgent‐start peritoneal dialysis (PD) vis‐à‐vis urgent‐start hemodialysis (HD) are not clear. We performed a systematic review and meta‐analysis of studies comparing the two modalities. Databases of PubMed, Embase, Ovoid, and Google Scholar were searched up to November 1, 2020. The primary outcome was mortality, and secondary outcomes were dialysis‐related infectious complications and mechanical complications. Risk ratios (RRs) were calculated for all outcomes. Seven studies were included. The pooled analysis revealed a statistically significant reduced risk of all‐cause mortality in patients undergoing urgent‐start PD as compared to urgent‐start HD (RR: 0.61, 95% confidence interval [CI] [0.40, 0.94], I2 = 56.34%). A meta‐analysis of dialysis‐related infectious complications indicated no statistically significant difference between the two modalities (RR: 0.66, 95% CI [0.29, 1.50], I2 = 69.62%). Our analysis revealed a statistically significant reduced risk of mechanical complications in patients undergoing urgent‐start PD (RR: 0.54, 95% CI [0.40, 0.73], I2 = 0%). To conclude, unadjusted data from observational studies are indicative of lower mortality and lower risk of mechanical complications with urgent‐start PD versus urgent‐start HD. The risk of infectious complications was not different between the two groups. Further studies with a larger sample size using propensity‐matched cohorts are needed to strengthen current evidence.
