Cerebrovascular endothelial cells (CECs), major component cells of the blood-brain barrier, can be injured by oxidative stress. Propofol can protect cells from oxidative injury. The aim of this study was to evaluate the effects of propofol on nitrosative stress-induced insults to CECs and its possible mechanisms.Primary CECs isolated from mouse cerebral capillaries were exposed to2 nitric oxide (NO)...
Vascular resection/reconstruction at the time of pancreatectomy is performed when limited vascular involvement is the only barrier to complete resection. Splenic vein (SV) ligation facilitates resection/reconstruction of the superior mesenteric vein (SMV)–portal vein (PV) confluence and widely exposes the superior mesenteric artery and celiac origin. If the inferior mesenteric vein does not provide...
We tested the hypotheses that an increase in systemic thrombin activity occurs in both disseminated intravascular coagulation (DIC) with the fibrinolytic phenotype and in acute coagulopathy of trauma shock (ACoTS), and that the patients diagnosed as having ACoTS overlap or are identical with those diagnosed as having DIC.We made a prospective study of 57 trauma patients, including 30 patients with...
Surveys are important research tools that permit the accumulation of information from large samples that would otherwise be impractical to collect. Resident surveys have been used frequently to monitor the quality of postgraduate training. Low response rates threaten the utility of this research tool. The purpose of this study was to determine the standard response rate of surveys administered to...
Previous studies have presented compelling data that a 1-month “boot-camp”–style course can be a highly effective mechanism for teaching and developing targeted technical skills. In the current study, we examine whether performance of these targeted skills is improved when residents are trained using directed, student-led (SL) learning methods compared with traditional instructor-led (IL) learning...
CC chemokine ligand 20 (CCL20) and CC chemokine receptor 6 are believed to stimulate the recruitment of neutrophils and activation of macrophages against bacterial pathogens through the activation of T helper cells. We analyzed the role of CCL20 in the acute phase of sepsis.The effect of a neutralizing, anti-mouse CCL20 monoclonal antibody (mAb) was examined in 2 murine models of sepsis: Cecal ligation...
It has been estimated that 750,000 to 1 million surgical-site infections (SSIs) occur in the United States each year, causing substantial morbidity and mortality. Triclosan-coated sutures were developed as an adjunctive strategy for SSI risk reduction, but a recently published systematic literature review and meta-analysis suggested that no clinical benefit is associated with this technology. However,...
The American College of Surgeons/Association of Program Directors in Surgery (ACS/APDS) National Skills Curriculum is a 3-phase program targeting technical and nontechnical skills development. Few data exist regarding the adoption of this curriculum by surgical residencies. This study attempted to determine the rate of uptake and identify implementation enablers/barriers.A web-based survey was developed...
The American College of Surgeons (ACS) and the Association of Program Directors in Surgery (APDS) jointly developed a standardized skills curriculum for surgical residents. This program was intended to be affordable, reproducible, reliable, and proficiency-based. Some experts have proposed mandating that all residency programs implement the curriculum. Although general surgery program directors have...
Esophageal cancer is an aggressive malignancy, and emerging data suggest that postoperative infections may promote cancer progression. Systemic exposure to lipopolysaccharide (LPS), a Gram-negative bacterial antigen involved in such infections, has been shown to increase cancer cell adhesion to the hepatic sinusoids in vivo. We investigated the direct impact of LPS on the migratory ability of esophageal...
Interprofessional education (IPE) in health care describes a process for training that places health care learners from different professional disciplines into an environment or situation in which shared or linked educational goals are pursued. IPE represents a new way of thinking about education as a value proposition directed at high-quality interprofessional patient care and as such is an innovative...
