BackgroundTraditional Helicobacter pylori (H. pylori) eradication therapies have shown efficacies below 80% in several studies, and their use has been accompanied by antibiotic-related side effects. Some recent studies have reported that supplementing standard therapies with probiotics can improve the efficacy and tolerability of Helicobacter pylori eradication therapy.ObjectiveTo assess the effects of probiotic supplementation on the eradication rates and therapy-related adverse event rates of anti-Helicobacter pylori regimens.MethodsWe searched PubMed, Medline, the Cochrane Central Registry of Controlled Trials and the Chinese Biomedical Database for eligible randomized controlled trials published through July, 2015. Review Manager 5.3 was used for all statistical analyses.ResultsThirteen randomized controlled trials involving a total of 2306 patients were included in our analysis. Intent-to-treat (ITT) analysis performed using a fixed-effects model (test for heterogeneity I2 = 45%) showed that the pooled relative risk (RR) of eradication was significantly higher in the probiotic supplementation group than in the control group [RR 1.15, 95% confidence interval (CI): 1.10–1.20, P<0.00001]. The incidence of total antibiotic-related side effects was lower in the probiotic supplementation group than in the control group, and the pooled RR (studies n = 9) was 0.71 (95% CI: 0.54–0.94, P = 0.02), as determined using a random-effects model (heterogeneity test I2 = 59%). Certain adverse events, such as nausea and vomiting (RR = 0.58, 95% CI 0.35–0.95, P = 0.03), diarrhea (RR = 0.51, 95% CI: 0.31–0.84, P = 0.008) and constipation (RR = 0.47, 95% CI: 0.28–0.80, P = 0.005), were reported at lower rates in the probiotic supplementation group than in the control group. Subgroup analysis showed that eradication rates were significantly improved in both adults (RR = 1.14, 95% CI: 1.09–1.19, P<0.00001) and children (RR = 1.24, 95% CI: 1.05–1.47, P = 0.01) in the probiotic supplementation group and that no regional differences between Europe (RR = 1.17, 95% CI: 1.09–1.24, P<0.00001) and Asia were present (RR = 1.14, 95% CI: 1.06–1.22, P = 0.0002). However, the total adverse event rate was not decreased in the adult group (RR = 0.80, 95% CI: 0.61–1.04, P = 0.1) or the Asian group (RR = 0.68, 95% CI: 0.39–1.18, P = 0.17). Subgroup analyses examining therapy regimens and treatment durations showed that probiotic supplementation increased eradication rates in the triple-therapy (RR = 1.18, 95% CI: 1.12–1.25, P<0.00001), seven-day treatment (RR = 1.21, 95% CI: 1.12–1.31, P<0.00001) and fourteen-day treatment (RR = 1.13, 95% CI: 1.06–1.20, P = 0.0002) groups. The incidence of antibiotic-related side effects was significantly reduced in all groups, with the exception of the quadruple-therapy subgroup (RR = 1.13, 95% CI: 0.60–2.13, P = 0.07) and the fourteen-day therapy subgroup (RR = 0.96, 95% CI 0.61–1.51, P = 0.86). Supplementation with Lactobacillus alone (RR = 1.24, 95% CI: 1.12–1.38, P<0.0001) or multi-strain probiotics (RR = 1.12...

Purpose: To evaluate emergence agitation and delirium signs in general anesthesia (GA) and postanesthesia care units (PACUs), and associated risk factors. Methods: Adult patients (n = 380) exposed to GA were recruited over a period of 1 year and five months for this study, and were assessed for emergence delirium (ED) using Richmond Agitation-Sedation Scale (RASS). Confusion Assessment Method for Intensive Care Unit (CAM-ICU) was used to assess delirium signs on admission to, and during stay in PACU at 30 min, 1 h, and at discharge. Signs consistent with delirium were classified as hyperactive or hypoactive based on a positive CAM-ICU assessment and RASS score. Multivariable logistic regression was used to assess potential risk factors for delirium such as age, American Society of Anesthesiologists (ASA) classification, and opioid and benzodiazepine (BZD) exposure during stay in PACU.
