    Objectives: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) provides a temporary support system for patients with cardiogenic shock refractory to conventional medical therapies. It has been reported that levosimendan may facilitate VA-ECMO weaning and improve survival. The primary objective of this review was to examine the effect of levosimendan use on VA-ECMO weaning and mortality in critically ill patients on VA-ECMO. Design: MEDLINE, EMBASE, and CENTRAL were searched. A pair of reviewers identified eligible clinical trials. Two reviewers extracted data and independently assessed the risk of bias. A random-effect model was used to combine data. The primary outcome was the success of weaning from VA-ECMO. Measurements and Main Results: Seven studies of observational design, including a total of 630 patients, were selected in the final analysis. The sample size ranged from ten-to-240 patients, with a mean age between 53 and 65 years, and more than half of them underwent cardiac surgeries. The VA-ECMO durations varied between four and 11.6 days. Overall, levosimendan use was significantly associated with successful weaning compared with control (odds ratio [OR] 2.89, 95% CI, 1.53-5.46; poverall effect = 0.001); I2 = 49%). For survival, six studies (n = 617) were included in the meta-analysis involving 326 patients in the levosimendan group and 291 in the comparator group. Pooled results showed a significantly higher survival rate in the levosimendan group (OR 0.46, 95% CI, 0.30-0.71; poverall effect = 0.0004; I2 = 20%). Conclusions: Levosimendan therapy was significantly associated with successful weaning and survival benefit in patients with cardiogenic or postcardiotomy shock needing VA-ECMO support for severe cardiocirculatory compromise. To date, there is limited literature and absence of evidence from randomized trials addressing the use of levosimendan in VA-ECMO weaning. This study may be considered a hypothesis-generating research for randomized controlled trials to confirm its findings

    PURPOSE: As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19-free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS: This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19-free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS: Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19-free surgical pathways. Patients who underwent surgery within COVID-19-free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19-free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score-matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19-free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION: Within available resources, dedicated COVID-19-free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks

    Abstract Introduction Laparoscopic cystectomy provides more favourable outcomes as regards the recurrence and subsequent clinical pregnancy rates. It is associated with significant reduction in the ovarian reserve due to the inevitable removal of unaffected ovarian tissue. The aim of our study was to evaluate the efficiency of Surgicel in preventing recurrence of endometriomas after their laparoscopic conservative management (cystectomy or drainage). Material and methods A randomized controlled trial included two hundred women (candidate for conservative laparoscopic management of ovarian endometriomas). They were randomized into four groups; group D in which patients underwent laparoscopic drainage of the endometrioma, group C in which patients underwent laparoscopic cystectomy of the endometrioma, group DS in which patients underwent laparoscopic drainage followed by insertion of Surgicel inside the cyst cavity & group CS in which patients underwent laparoscopic cystectomy of the endometrioma followed by insertion of Surgicel inside the remaining ovarian tissues. All patients were followed up for 2 years & the primary outcome was the recurrence of endometriomas in the ipsilateral ovary & the postoperative ovarian reserve was reassessed as a secondary outcome. Results The Surgicel-treated groups had significantly lower hazard of recurrence compared to untreated groups (p = 0.004). Group CS had significantly lower hazard of recurrence compared to Group D & C (p = 0.014, 0.046 respectively). Group DS had significantly lower hazard of recurrence compared to Group D (p = 0.039) but it not significantly different from Group C (p = 0.112). Group DS had the lowest drop of AMH and was significantly lower than the other three groups. Conclusion Surgicel reduces effectively the recurrence risk of endometriomas and its use during laparoscopic drainage is an effective alternative for traditional laparoscopic cystectomy with minimal affection of the patient ovarian reserve.
