Exploring Medical Students' Perceptions of Organ Procurement: Need for a Formalized Medical Student Curriculum.

OBJECTIVE: We evaluated the medical student experience with a deceased-donor multiorgan procurement program at a single center. The program provided the opportunity to assist with organ procurement, but no formal curriculum was offered. DESIGN, SETTING, PARTICIPANTS: In 2018, medical students who registered for the program between 2014 and 2017 completed a voluntary survey about the experience and its impact on surgery interest and organ donation knowledge and advocacy. RESULTS: Of 139 respondents, 53.3% (N = 74) of students participated in at least one procurement. The experience was resoundingly positive: 81.7% (N = 58) believed it exceeded expectations, with less than one-third missing class and only 4.3% (N = 3) reporting a negative impact on academics. Although 60.6% (N = 43) students studied prior to procurement, 57.8% (N = 41) expressed the need for increased preparation. Preferred learning modalities included videos, discussion with the transplant fellows, and focused anatomy overview. Following participation, 53.5% (N = 38) of students had increased interest in pursuing an acting internship and career in surgery. However, participation was not associated with improved familiarity with organ donation concepts or advocacy. CONCLUSIONS: Adding a structured curriculum may turn medical students from passive observers into active learners, maximizing the educational value of procurement and better equipping future providers to promote organ donation.

Colorectal sarcoma: more than a gastrointestinal stromal tumor.

Primary colorectal sarcomas have been defined as a rare and diverse group of mesenchymal cancers distinct from gastrointestinal stromal tumors (GISTs). Primary colorectal sarcomas have been recognized as a distinct entity from GISTs due to the dramatically worse prognosis these sarcomas carry. Also, primary colorectal sarcomas when compared to the more common colorectal adenocarcinoma, demonstrate more aggressive biology, present at a younger age and carry worse outcomes. At this time, surgery remains the mainstay of treatment and adjuvant chemotherapy has an unclear role in treatment of primary colorectal sarcoma. This paper attempts to review the available data regarding primary colorectal sarcomas.

Risk factors and outcomes of carbapenem-resistant Klebsiella pneumoniae infections in liver transplant recipients.

Carbapenem-resistant Klebsiella pneumoniae (CRKP) infection is increasing in incidence and is associated with increased mortality in liver transplantation (LT) recipients. We performed a retrospective cohort study of all patients transplanted between January 2010 and January 2013 to identify the incidence and risk factors for post-LT CRKP infection and evaluate the impact of this infection on outcomes in a CRKP-endemic area. We studied 304 recipients, of whom 20 (6.6%) developed CRKP and 36 (11.8%) carbapenem-susceptible Klebsiella pneumoniae (CSKP) infections in the year following LT. Among the 20 recipients with post-LT CRKP infection, 8 (40%) were infected in ≥ 2 sites; 13 (65%) had surgical site-intra-abdominal infections; 12 (60%) had pneumonia; and 3 (15%) had a urinary tract infection. There were 6 patients with a CRKP infection before LT, 5 of whom developed a CRKP infection after LT. Significant risk factors for post-LT CRKP infection in multivariate analysis included laboratory Model for End-Stage Liver Disease at LT (odds ratio [OR], 1.07; P = 0.001), hepatocellular carcinoma (OR, 3.19; P = 0.02), Roux-en-Y biliary choledochojejunostomy (OR, 3.15; P = 0.04), and bile leak (OR, 5.89; P = 0.001). One-year estimated patient survival was 55% (95% confidence interval, 31%-73%), 72% (55%-84%), and 93% (89%-96%), for patients with CRKP, CSKP, and no Klebsiella pneumoniae infection, respectively. In multivariate analysis, CRKP (hazard ratio [HR], 6.92; P < 0.001) and CSKP infections (CSKP, HR, 3.84; P < 0.001), as well as bile leak (HR, 2.10; P = 0.03) were the strongest predictors of post-LT mortality. In an endemic area, post-LT CRKP infection is common, occurring in 6.6% of recipients, and is strongly associated with post-LT mortality. Improved strategies for screening and prevention of CRKP infection are urgently needed.
