ABSTRACT
BACKGROUND: Data on rate, risk factors, and consequences of early reoperation after liver transplantation are still limited. STUDY DESIGN: Single-center retrospective analysis of data of 428 patients, who underwent liver transplantation in period between January 2009 and December 2014. Univariate and multivariate analysis were used to study the risk factors of early reoperation and its impact on graft survival. RESULTS: Of 428 patients, 74 (17.3%) underwent early reoperation. Of them, 46 (62.2%) underwent reoperation within the first week and 28 (37.8%) underwent reoperation later than 1 week after transplantation. With multivariate analysis, significant risk factors of early reoperation included pretransplant ICU admission, previous abdominal surgery and diabetes. Early reoperation itself was not found to be an independent predictor of graft loss. However, early reoperation later than 7 days from transplant was found to be independent predictor of graft loss (odds ratio [OR] = 5.125; 95% CI, 1.358-19.552; P = .016). In our series, other independent predictors of graft loss were MELD score (P = .010) and operative time (P = .048). CONCLUSIONS: This analysis demonstrates that early reoperations later than a week appear to negatively impact the graft survival. The timing of early reoperation should be a focus of additional studies.

BACKGROUND: Split liver transplantation allows for expansion of the pool of organs available for pediatric liver transplantation. The impact of sharing segments of the same liver between centers has not been studied. STUDY DESIGN: Retrospective analysis of 24 pediatric split liver transplant cases in a recent cohort. We evaluated the outcomes of pediatric recipients who shared organs with adult patients in our own center (group A) compared to recipients who shared organs with adult patients in other centers. (group B). RESULTS: One-, 3-, and 5-year graft survival for group A was 100%, 100%, and 100% vs 83%, 71%, and 57% for group B (P = .039). Postoperative complications included biliary complications (41.7% in group A vs 50% in group B, P = .682), vascular complications (8.3% in group A vs 41.7% in group B, P = .059), and postoperative bleeding (16.7% in group A vs 25% in group B, P = .615). High-grade Clavien-Dindo complications were 0% in group A vs 33.3% in group B, P = .028. CONCLUSIONS: Organ sharing between centers appears to be associated with significantly poorer graft survival. Possible explanations include greater procurement-related injury or suboptimal vessel distribution. Future larger studies focused on this area may be helpful to formulate policy considerations.

BACKGROUND: Maternal, perinatal and neonatal mortality remains high in low-income countries. We evaluated community and facility-based interventions to reduce deaths in three districts of Malawi. METHODS: We evaluated a rural participatory women's group community intervention (CI) and a quality improvement intervention at health centres (FI) via a two-by-two factorial cluster randomized controlled trial. Consenting pregnant women were followed-up to 2 months after birth using key informants. Primary outcomes were maternal, perinatal and neonatal mortality. Clusters were health centre catchment areas assigned using stratified computer-generated randomization. Following exclusions, including non-birthing facilities, 61 clusters were analysed: control (17 clusters, 4912 births), FI (15, 5335), CI (15, 5080) and FI + CI (14, 5249). This trial was registered as International Standard Randomised Controlled Trial [ISRCTN18073903]. Outcomes for 14,576 and 20,576 births were recorded during baseline (June 2007-September 2008) and intervention (October 2008-December 2010) periods. RESULTS: For control, FI, CI and FI + CI clusters neonatal mortality rates were 34.0, 28.3, 29.9 and 27.0 neonatal deaths per 1000 live births and perinatal mortality rates were 56.2, 55.1, 48.0 and 48.4 per 1000 births, during the intervention period. Adjusting for clustering and stratification, the neonatal mortality rate was 22% lower in FI + CI than control clusters (OR = 0.78, 95% CI 0.60-1.01), and the perinatal mortality rate was 16% lower in CI clusters (OR = 0.84, 95% CI 0.72-0.97). We did not observe any intervention effects on maternal mortality. CONCLUSIONS: Despite implementation problems, a combined community and facility approach using participatory women's groups and quality improvement at health centres reduced newborn mortality in rural Malawi.
