BACKGROUND America's aging population has led to an increase in the number of elderly patients necessitating emergency general surgery. Previous studies have demonstrated that increased frailty is a predictor of outcomes in medicine and surgical patients. We hypothesized that use of a modification of the Canadian Study of Health and Aging Frailty Index(More)
BACKGROUND Open Roux-en-Y gastric bypass has become the gold standard for bariatric surgery. Safety has always been a concern with this elective surgery, especially among the general public. With increasing numbers of bariatric surgeries being performed, the public eye is once again focused on safety and outcomes for these patients. METHODS Nine hundred(More)
BACKGROUND Universal agreement on criteria for acute renal failure (ARF) is lacking. The purpose of the current study was to determine which of 6 definitions for ARF best predicted clinical outcomes in postoperative cardiothoracic surgery (CTS) patients. METHODS Criteria for ARF were retrospectively applied to 1,085 CTS patients. General linear models(More)
AIMS The study investigated the physiology of Amaricoccus kaplicensis to determine whether it could outcompete polyphosphate accumulating bacteria in activated sludge systems removing phosphorus, by preferentially assimilating substrates in the anaerobic stages of these processes. METHODS AND RESULTS The storage processes were investigated under(More)
INTRODUCTION Current literature tends not to adjust for biases in patient selection attributable to comorbidities that could provide alternate explanations for length of stay differences in laparoscopic versus open colectomy. We hypothesized that utilizing the National Surgical Quality Improvement Program (NSQIP) dataset and acuity adjustment methods would(More)
OBJECTIVE Technology currently exists for the application of remote guidance in the laparoscopic operating suite. However, these solutions are costly and require extensive preparation and reconfiguration of current hardware. We propose a solution from existing technology, to send video of laparoscopic cholecystectomy to the Blackberry Pearl device (RIM(More)
BACKGROUND We sought to pilot and initiate validation of a surgical drainage model. METHODS We designed a laboratory model to compare Jackson-Pratt surgical drains using 3 soups to emulate body fluids of serous, purulent, and necrotic debris. Each drain was trialed with each of the 3 fluids. Time and completeness of drainage were recorded. A survey of(More)
BACKGROUND Unplanned postoperative reintubation increases the risk of mortality, but associated factors are unclear. OBJECTIVE To elucidate factors associated with increased mortality risk in patients with unplanned postoperative reintubation. DESIGN Retrospective study. Patients older than 40 years who underwent unplanned reintubation from 2005 to 2010(More)
