Despite increases in surgical capacity in Malawi, minimal data exist on postoperative complications. Identifying surgical management gaps and targeting quality improvement requires detailed, longitudinal complications, and outcome data that assess surgical safety and efficacy.

We conducted a 6-mo prospective, observational study of patients >12y after laparotomy at a tertiary hospital in Lilongwe, Malawi. Outcomes included postoperative complications and mortality. The seniormost rounding physician determined complication diagnoses. Bivariate and Poisson regression analyses identified predictors of mortality.

Only patients undergoing emergent laparotomy (77.8%) died before discharge, so analysis excluded elective cases. Of 189 patients included, the median age was 33.5 y (IQR 22-50.5), 22 (12.2%) had prior abdominal surgery, and 11 (12.1%) were human immunodeficiency virus-positive. Gastrointestinal perforation was the most common diagnosis (35.5%). The most common procedures were primary gastrointesStrategies to improve operative mortality in Malawi should prioritize postoperative surveillance and management and continued outcomes reporting.

Esophageal adenocarcinoma (EAC) is a lethal malignancy with poor prognosis. Pharmacologic inhibitors of inflammation, such as statins, have been shown to decrease the risk of development and progression of esophageal cancer, but the mechanism of this protection is unclear. The objective of this study was to elucidate the effect of statins on toll-like receptor 4-mediated-proliferation of human EAC cells and identify the mechanism responsible for these observed effects.

Human EAC cells (OE33 and FLO1) were treated with simvastatin or atorvastatin for increasing doses and time periods. Toll-like receptor 4 (TLR4) expression was assessed. Cells were pretreated with statin followed by lipopolysaccharide (LPS). Cell proliferation and expression of signaling proteins were evaluated. FLO1 cells were injected into the flank of nude mice. Mice received intraperitoneal injections of simvastatin, atorvastatin, or control solution and tumor volume was measured.

OE33 and FLO1 cells demonstrated decreased TLR4 expression after treatment with simvastatin or atorvastatin for 8h (P<0.05). LPS increased proliferation, whereas pretreatment with statin abolished this response (P<0.05). Statins decreased expression and activation of LPS-induced signaling proteins, including MyD88, TRAF6, Akt, and NF-κB (P<0.05). Mice receiving daily statin injections demonstrated smaller tumors than control mice (P<0.001 at day 33).

Treatment of EAC cells with simvastatin or atorvastatin decreases TLR4-mediated proliferation and invivo tumor growth. Decreased TLR4 expression and subsequent reduction in MyD88-dependent signaling could be a mechanism by which statins act to reduce tumor growth rates.

FABP3 is a member of the fatty acid-binding protein (FABP) family, whose role in various cancers has been reported in the past. However, little is known about the role that FABP3 plays in gastrointestinal stromal tumors (GISTs).

FABP3 expression was analyzed in 119 patients with GISTs using immunohistochemistry and tissue microarrays to interrogate the relationship between expression and prognosis. Kaplan-Meier analysis was used to calculate patient survival rates using complete follow-up data and to evaluate the potential prognostic value of FABP3 using Cox regression analysis.

FABP3-positive signals were detected as brown particles located in the cytoplasm using immunohistochemistry. Among the 119 tissue samples, we observed high FABP3 expression in 64 and low or negative expression in 55. Immunohistochemical analyses suggested that FABP3 expression was significantly correlated with tumor size (P=0.006), mitotic index (P=0.016), gross classification (P=0.048), and AFIP-Miettinen risk classification (P=0.007). Multiple logistic regression analysis showed that the expression of FABP3 was significantly associated with tumor size (P=0.021). Kaplan-Meier survival curves showed that patients with GISTs with low expression of FABP3 and classified with a very low to moderate AFIP-Miettinen risk had better prognosis. selleck chemicals llc Multivariate analysis further showed that high expression of FABP3 (P=0.017) was significantly associated with poor 5-year overall survival.

High FABP3 expression has a prognostic value for patients with GISTs.

Depression has been linked to increased morbidity and mortality in patients after surgery. The purpose of this study is to investigate the impact of documented depression diagnosis on in-hospital postoperative outcomes of patients undergoing colorectal surgery.

Patients from the National Inpatient Sample (2002-2017) who underwent proctectomies and colectomies were included. The outcomes measured included total hospital charge, length of stay, delirium, wound infection, urinary tract infection (UTI), pneumonia, deep vein thrombosis, pulmonary embolism, mortality, paralytic ileus, leak, and discharge trends. Multivariable logistic and Poisson regression analyses were performed.

Of the 4,212,125 patients, depression diagnosis was present in 6.72% of patients who underwent colectomy and 6.54% of patients who underwent proctectomy. Regardless of procedure type, patients with depression had higher total hospital charges and greater rates of delirium, wound infection, UTI, leak, and nonroutine discharge, with omes but experience lower risk of in-hospital mortality after undergoing colorectal surgery. Further studies are needed to validate and fully understand the driving factors behind this.Medulloblastoma (MB) is a highly malignant cerebellar tumor predominantly diagnosed during childhood. Driven by pathogenic activation of sonic hedgehog (SHH) signaling, SHH subgroup MB (SHH-MB) accounts for nearly one-third of diagnoses. Extensive molecular analyses have identified biologically and clinically relevant intertumoral heterogeneity among SHH-MB tumors, prompting the recognition of novel subtypes. Beyond germline and somatic mutations promoting constitutive SHH signaling, driver alterations affect a multitude of pathways and molecular processes, including TP53 signaling, chromatin modulation, and post-transcriptional gene regulation. Here, we review recent advances in the underpinnings of SHH-MB in the context of molecular subtypes, clarify novel somatic and germline drivers, highlight cellular origins and developmental hierarchies, and describe the composition of the tumor microenvironment and its putative role in tumorigenesis.
