Aim The aim of this study was to seek an association between the control of type 2 diabetes mellitus (T2DM), as determined by hemoglobin A1c (HbA1c) levels, and the outcome of colorectal cancer (CRC). Methods We performed a retrospective review of patients with T2DM who had CRC diagnosed between 1997 and 2001. We defined well-controlled T2DM as HbA1c < 7.5%(More)
BACKGROUND The purpose of this study was to compare risk factors for the development of incisional versus organ/space infections in patients undergoing colorectal surgery. METHODS An institutional review board-approved retrospective review was performed examining a 4-year period (January 2002 to December 2005). Patients were included if they had undergone(More)
PURPOSE To determine preoperative risk factors predictive of adverse outcomes after gastric bypass surgery. SUMMARY BACKGROUND DATA Gastric bypass results in sustained weight loss for seriously obese patients, but perioperative complications can be formidable. Preoperative risk assessment is important to establish the risk-benefit ratio for patients(More)
BACKGROUND The implementation of new therapeutic options for the management of metastatic colon cancer mandates a revisit to apoptosis and its role in colon cancer tumorigenesis with an emphasis on the mechanisms leading to chemotherapeutic resistance and immune system evasion of colon cancer cells. DATA SOURCES Literature regarding molecular apoptosis(More)
CONTEXT Pancreatic schwannomas are rare neoplasms. These tumors vary in size and two thirds are partially cystic which grossly mimic pancreatic cystic lesions. Computed tomography and magnetic resonance imaging are the primary initial imaging modalities. Definitive diagnosis is typically made at the time of laparotomy following biopsy. Surgical resection is(More)
OBJECTIVE To determine if an evidence-based practice bundle would result in a significantly lower rate of surgical site infections (SSIs) when compared with standard practice. DESIGN Single-institution, randomized controlled trial with blinded assessment of main outcome. The trial opened in April 2007 and was closed in January 2010. SETTING Veterans(More)
BACKGROUND Colon cancer becomes resistant to apoptosis as it acquires metastatic potential. SW480 and SW620 colon cancer cells were established from the same patient at different stages of tumor progression. The stage III colorectal cancer cell line (SW620) is more resistant to apoptosis. In the present report, we investigated the apoptotic gene products(More)
The recent discovery of Smac and the elucidation of its structure and function have led to the rapid development of Smac mimetics, comprising Smac derivative and mimicking molecules, for use in cancer treatment. Smac is an endogenous proapoptotic protein that resides in the mitochondria and is released when a cell is triggered to undergo programmed cell(More)
Bariatric surgery is being performed in increasing numbers in an era when reimbursements are being reduced. Academic health centers bear the responsibility for training surgeons to perform these operations yet must keep costs to a minimum and retain high quality. The UCLA Bariatric Surgery Program developed a clinical pathway for the pre- and postoperative(More)
Lecanicillium fungicola was selected among 15 strains as chitinase producer and it was used to obtain the crude enzyme (UFL) in submerged fermentation (SF) with added chitin. The UFL displayed at pH 6 and 40 8C the highest endochitinase (Endo) and N-acetylhexosaminidase (NHase) activities, 747 and 410 U/mg, respectively. Four bands of proteins with(More)
