BACKGROUND A novel computer simulator is now commercially available for robotic surgery using the da Vinci(®) System (Intuitive Surgical, Sunnyvale, CA). Initial investigations into its utility have been limited due to a lack of understanding of which of the many provided skills modules and metrics are useful for evaluation. In addition, construct validity(More)
Purified protein derivatives (PPD) prepared in the USA were compared with those prepared in Australia by a private company (CSL Veterinary) for use with a commercial gamma interferon (gamma-IFN) assay for diagnosis of bovine tuberculosis. The effect of skin testing on results of the gamma-IFN assay was determined, and results were compared when blood(More)
Bovine tuberculosis, caused by Mycobacterium bovis, is a pathogen of growing concern in free-ranging wildlife in Africa, but little is known about the disease in Tanzanian wildlife. Here, we report the infection status of Mycobacterium bovis in a range of wildlife species sampled from protected areas in northern Tanzania. M. bovis was isolated from 11.1%(More)
Depressed cell-mediated immunity in human visceral leishmaniasis (VL) (also known as kala-azar), revealed as the inability of peripheral blood mononuclear cells (PBMCs) to respond to Leishmania antigen, remains a hallmark of and is thought to underlie the progressive nature of this disease. We recently reported the ability of a whole-blood, gamma interferon(More)
BACKGROUND For the past two decades multiple series have documented that liver resection has become safer. The purpose of this study was to determine the current status of hepatic resection in the USA by analysing the multi-institutional experience within the National Surgical Quality Improvement Program (NSQIP) dataset. METHODS Of the 363,897 cases in(More)
BACKGROUND As national quality initiatives are increasing requirements for individual physician data, our department of surgery initiated a surgeon-specific reporting (SSR) program to assess the value of personal knowledge on individual performance quality. We sought to evaluate the use of SSR as a tool to enable surgeons to assess and improve their(More)
The objective was to evaluate cellular immune response of captive white-tailed deer (Odocoileus virginianus) to live Mycobacterium bovis bacille Calmette Guerin (BCG) vaccination and to determine diagnostic implications of these responses. In vitro proliferative and interferon-gamma (IFN-gamma) responses to M. bovis purified protein derivative (PPD) were(More)
OBJECTIVE To document the incidence, mortality rate, and risk factors for sepsis and septic shock compared with pulmonary embolism and myocardial infarction in the general-surgery population. DESIGN Retrospective review. SETTING American College of Surgeons National Surgical Quality Improvement Program institutions. PATIENTS General-surgery patients(More)
BACKGROUND Sepsis is the leading cause of mortality in noncoronary intensive care units. Recent evidence based guidelines outline strategies for the management of sepsis and studies have shown that early implementation of these guidelines improves survival. We developed an extensive logic-based sepsis management protocol; however, we found that early(More)
BACKGROUND Sepsis is a deadly and potentially preventable complication. A better understanding of sepsis in general surgery patients is needed to help direct resources to those patients at highest risk for death from sepsis. METHODS We identified risk factors for sepsis in general surgery patients by using the National Surgical Quality Improvement Project(More)
