We sought to characterize sex-based differences in access to deceased donor liver transplantation. Scientific Registry of Transplant Recipients data were used to analyze n = 78 998 adult candidates listed before (8/1997-2/2002) or after (2/2002-2/2007) implementation of Model for End-Stage Liver Disease (MELD)-based liver allocation. The primary outcome was(More)
The effect of demand for kidney transplantation, measured by end-stage renal disease (ESRD) incidence, on access to transplantation is unknown. Using data from the U.S. Census Bureau, Centers for Medicare & Medicaid Services (CMS) and the Organ Procurement and Transplantation Network/Scientific Registry of Transplant Recipients (OPTN/SRTR) from 2000 to(More)
OBJECTIVE To determine whether controlling for differences in the use of invasive therapy affects racial/ethnic differences in survival of early-stage hepatocellular carcinoma (HCC). DESIGN A retrospective cohort study using Surveillance, Epidemiology, and End Results (SEER) HCC data. Invasive therapy was defined as tumor ablation, hepatectomy, or liver(More)
Access to liver transplantation is reportedly inequitable for racial/ethnic minorities, but inadequate adjustments for geography and disease progression preclude any meaningful conclusions. We aimed to evaluate the association between candidate race/ethnicity and liver transplant rates after thorough adjustments for these factors and to determine how(More)
The effect of obesity on perioperative outcomes following hepatic resection is not clearly defined. We sought to understand the implications of obesity on post-hepatectomy outcomes in a nationally represented cohort of patients. Using a retrospective cohort design, we studied the effect of obesity on complications and 30-day mortality using multivariable(More)
Clinical Presentation A previously healthy 37-year-old woman complained of episodic right upper abdominal pain. An extensive clinical workup had been negative, including physical examination, upper endoscopy, complete blood count, comprehensive metabolic panel, and coagulation studies. Contrast-enhanced computed tomography (CT) of the abdomen and pelvis(More)
BACKGROUND Pregnancy after solid organ transplant is a significant priority for transplant recipients but how patients report being counseled is unknown. METHODS We performed a single-center retrospective cohort study and telephone survey of female patients ages 18-49 at the time of kidney, pancreas, or liver transplant from 2000 to 2012 (n = 532). Data(More)
We aimed to identify recipient, donor and transplant risk factors associated with graft failure and patient mortality following donation after cardiac death (DCD) liver transplantation. These estimates were derived from Scientific Registry of Transplant Recipients data from all US liver-only DCD recipients between September 1, 2001 and April 30, 2009 (n =(More)
OBJECTIVE We sought to use a multi-institutional, prospective, clinical database to better understand adverse outcomes in chronic liver disease (CLD) patients undergoing colorectal surgery. BACKGROUND CLD confers significant perioperative risk. However, there are little population-based data available for prognostication and risk stratification in these(More)
BACKGROUND Post-lung transplant reperfusion edema (PLTRE) and its more severe form, primary graft failure (PGF), occur in 10% to 60% of lung transplant recipients. We hypothesized that PLTRE and PGF would be associated with an elevated proinflammatory cascade and that the allograft would be the source of cytokine appearance in the circulation. METHODS(More)
