Randomized Controlled Trial Multicenter Study
Molecular Staging of Sentinel Lymph Nodes Identifies Melanoma Patients at Increased Risk of Nodal Recurrence.
Molecular staging of sentinel lymph nodes (SLNs) may identify patients who are node-negative by standard microscopic staging but are at increased risk for regional nodal recurrence; such patients may benefit from completion lymph node dissection (CLND). ⋯ Patients with microscopically negative/PCR+ SLN have an increased risk of nodal recurrence that was mitigated by CLND. Although CLND did not affect OS, these data suggest that molecular detection of melanoma-specific mRNA in the SLN predicts a greater risk of nodal recurrence and deserves further study.

Acute Fibrinolysis Shutdown after Injury Occurs Frequently and Increases Mortality: A Multicenter Evaluation of 2,540 Severely Injured Patients.
Fibrinolysis is a physiologic process that maintains microvascular patency by breaking down excessive fibrin clot. Hyperfibrinolysis is associated with a doubling of mortality. Fibrinolysis shutdown, an acute impairment of fibrinolysis, has been recognized as a risk factor for increased mortality. The purpose of this study was to assess the incidence and outcomes of fibrinolysis phenotypes in 2 urban trauma centers. ⋯ Fibrinolysis shutdown is the most common phenotype on admission and is associated with increased mortality. These data provide additional evidence of distinct phenotypes of coagulation impairment and that individualized hemostatic therapy may be required.

Stage-Specific Prognostic Effect of Race in Patients with Resectable Gastric Adenocarcinoma: An 8-Institution Study of the US Gastric Cancer Collaborative.
Gastric cancer constitutes a major public health problem. This study sought to evaluate the relevance of race in gastric cancer and its prognostic effect in the overall outcomes of patients with gastric adenocarcinoma. ⋯ Patients of Asian race undergoing curative gastrectomy for gastric adenocarcinoma appear to have a better prognosis stage for stage. Further studies are required to elucidate the underlying etiology of this phenomenon.

Delayed repair of congenital diaphragmatic hernia (CDH) for days or longer has become standard, allowing improved stabilization for many, but potentially complicating treatment in severely affected infants who require extracorporeal membrane oxygenation (ECMO) and arrive unrepaired. Survival in left liver-up CDH, the most severe anatomic subset, averages 45% in published studies, with deaths often occurring in patients who failed to improve on ECMO and are repaired late, or not at all. Reliable early prediction of ECMO risk in these patients could identify the best candidates for repair before ECMO. We sought to predict ECMO risk in left liver-up CDH, and to further evaluate survival stratified by surgical timing in these patients. ⋯ Early repair of left liver-up CDH before ECMO results in improved survival. Multivariate models can accurately assess risk for ECMO at 1 hour of life, permitting stratification of CDH surgical timing to maximize survival potential while minimizing risk.
