BACKGROUND The development of acute renal failure and myocardial infarction (MI) following colectomy prolongs recovery and is associated with worse outcomes. The purpose of this study is to identify perioperative factors that predispose patients to an adverse cardiac or renal complication. MATERIALS AND METHODS We conducted a retrospective review of(More)
BACKGROUND Clostridium difficile (CD), a gram-positive rod bacterium, resides normally within the human colon. Antibiotic treatment alters normal colonic flora, potentiating abnormal overgrowth of CD. METHODS This study examined the 2004 to 2006 Nationwide Inpatient Sample to determine outcomes of CD colitis after 695,010 elective colonic resections. (More)
BACKGROUND Hemoglobin levels must be obtained through blood draws, which are invasive, time-consuming, and provide only 1 data point at a time rather than continuous measurements. The Masimo Radical-7 SpHb Station (Masimo Corporation, Irvine, CA) has been shown by its manufacturers to provide accurate noninvasive hemoglobin measurements in physiologically(More)
BACKGROUND There remains strong opinion but very little data to support the way that the resultant mesenteric defect is handled following colectomy. Despite case reports of internal hernias and subsequent bowel obstruction requiring operative intervention, no larger series have evaluated this question. MATERIALS AND METHODS Retrospective review of(More)
BACKGROUND Whereas Crohn's disease is traditionally thought to represent a wasting disease, little is currently known about the incidence and impact of obesity in this patient cohort. OBJECTIVE This study aimed to evaluate the perioperative outcomes in patients with Crohn's disease who were obese vs those who were not obese undergoing major abdominal(More)
BACKGROUND Inferior outcomes in younger patients with colorectal cancer may be associated with multiple factors, including tumor biology, delayed diagnosis, disparities such as access to care, and/or treatment differences. OBJECTIVE This study aims to examine age-based colorectal cancer outcomes in an equal-access health care system. DESIGN This study(More)
BACKGROUND Humanitarian medical care is an essential task of the deployed military health care system. The purpose of this study was to analyze referral acceptance in treating injured local national patients during Operation Enduring Freedom. METHODS A prospective observation study of local nationals who were referred for humanitarian trauma care in(More)
INTRODUCTION Operating room time is highly resource intensive, and delays can be a source of lost revenue and surgeon frustration. Methods to decrease these delays are important not only for patient care, but to maximize operating room resource utilization. The purpose of this study was to determine the root cause of operating room delays in a standardized(More)
BACKGROUND Ultrasonographic (US) assessment of abdominal aortic aneurysms is typically performed by measuring maximal aneurysm diameter from two-dimensional images. These measurements are prone to inaccuracies owing to image planes and interobserver variability. The purpose of this study was to compare the variability in diameter, cross-sectional area(More)
BACKGROUND The expression of progesterone receptor membrane component 1 (PGRMC1) in breast cancer has generated interest in this recently discovered protein because of its role in tumorigenesis. However, correlations between patient age, PGRMC1 gene expression, breast cancer morphology, and breast cancer stage have not been adequately studied. Furthermore,(More)
