The impact of endometrial injury on reproductive outcomes: results of an updated meta-analysis.

ABSTRACT: Background:It is still unclear whether endometrial injury (EI) has a beneficial effect on reproductive outcomes, and if so, the optimal procedure characteristics are not clear. All previous papers concluded that more research is needed, and as additional studies were recently published, the insights on EI have changed significantly. Methods:Searches were conducted in MEDLINE, Embase, Web of Science, and Cochrane Library, to identify randomized controlled trials examining the EI effect on IVF outcomes in women at least one previous failed cycle. Results:2015 references were identified through database searching. Ultimately, 17 studies were included, involving 3016 patients. Clinical pregnancy rate (CPR) (RR = 1.19, [95% CI 1.06-1.32], P = .003) and live birth rate (LBR) (RR = 1.18, [95%CI 1.04-1.34], P = .009) were significantly improved after EI. Number of previous failed cycles, maternal age, and hysteroscopy were found to be relevant confounders. Higher CPR and LBR were found when EI was performed twice, while performing EI once did not significantly improve reproductive rates. Conclusion:According to the present meta-analysis, EI may be offered to younger patients with few previous failed cycles and should be additionally studied in an RCT comparing different timing and more than one EI before treatment.

Project description:BackgroundPerioperative goal-directed therapy (GDT) reduces the risk of renal injury. However, several questions remain unanswered, such as target, kind of patients and surgery, and role of fluids and inotropes. We therefore update a previous analysis, including all studies published in the meanwhile, to clarify the clinical impact of this strategy on acute kidney injury.Main bodyRandomized controlled trials enrolling adult patients undergoing major surgery were considered. GDT was defined as perioperative monitoring and manipulation of hemodynamic parameters to reach normal or supranormal values by fluids alone or with inotropes. Trials comparing the effects of GDT and standard hemodynamic therapy were considered. Primary outcome was acute kidney injury, whichever definition was used. Meta-analytic techniques (analysis software RevMan, version 5.3) were used to combine studies, using random-effect odds ratios (OR) and 95% confidence intervals (CI). Trial sequential analyses were performed including all trials and considering only low risk of bias trials. Sixty-five trials with an overall sample of 9308 patients were included. OR for the development of renal injury was 0.64 (95% CI, 0.62-0.87; p = 0.0003), with no statistical heterogeneity. Trial sequential analyses and sensitivity analysis including studies with low risk of bias confirmed the main results. A significant decrease in renal injury rate was observed in studies that adopted cardiac output and oxygen delivery as hemodynamic target and that used both fluids and inotropes. The postoperative kidney injury rate was significantly lower in trials enrolling "high-risk" patients and major abdominal and orthopedic surgery.Short conclusionThe present meta-analysis suggests that targeting GDT to perioperative systemic oxygen delivery, by means of fluids and inotropes, can be the best way to improve renal perfusion and oxygenation in high-risk patients undergoing major abdominal and orthopedic surgery.

Project description:Background/Aims:An updated systematic review and meta-analysis was conducted to assess the effect of prophylactic dexamethasone for tracheal intubation of general anesthesia on postoperative sore throat (POST). Methods:Comprehensive literature search of databases for randomized controlled trials (RCTs), including Embase, PubMed, and Cochrane Library, which evaluate the effect of prophylactic dexamethasone on POST was conducted. RevMan 5.0 and STATA 12.0 software were used to perform meta-analyses. Results:Fourteen RCTs totaling 1,837 patients were included for analysis. Compared with placebo, a significant reduction in the incidence of POST (OR 0.44, 95% CI 0.33-0.58, P<0.00001), hoarseness (OR 0.42, 95% CI 0.31-0.58, P<0.00001), and postoperative nausea and vomiting (PONV) (OR 0.06, 95% CI 0.03-0.14, P<0.00001) and a comparable incidence of cough (OR 0.59, 95% CI 0.19-1.89, P=0.38) was described in patients receiving dexamethasone, with or without concomitant drugs. Dexamethasone ?0.2 mg/kg had a statistically greater impact on reducing the incidence of POST than dexamethasone 0.1-0.2 mg/kg, while dexamethasone ?0.1 mg/kg did not. Dexamethasone was as effective as other drugs such as ondansetron, magnesium sulfate, ketamine gargle, betamethasone gel, and ketorolac for reducing POST (OR 0.70, 95% CI 0.46-1.07, P=0.10). Dexamethasone plus a different drug was more effective than dexamethasone alone for reducing the incidence of POST at 24 hours (OR 0.40, 95% CI 0.21-0.77, P=0.006). Compared with controls, a statistically higher blood glucose level was the only adverse event during the immediate postoperative period in patients receiving dexamethasone. Conclusions:Intravenous dexamethasone ?0.2 mg/kg within 30 minutes before or after induction of general anesthesia should be recommended as grade 1A evidence with safety and efficacy in reducing the incidence of POST, hoarseness, and PONV in patients without pregnancy, diabetes mellitus, or contraindications for corticosteroids.
