Long-term risk of death in patients with hidradenitis suppurativa.

Background: Hidradenitis suppurativa (HS) is associated with substantial morbidity. Few studies have addressed the natural history and mortality rates associated with HS. A higher risk of cardiovascular death in patients with HS has been reported.

Aspirin, Statins, Non-aspirin NSAIDs, Metformin, and the Risk of Biliary Cancer: A Swedish Population-Based Cohort Study.

Background: Chemoprevention for biliary tract cancers (BTC), which comprise intrahepatic cholangiocarcinoma (iCCA), extrahepatic cholangiocarcinoma (eCCA), and gallbladder cancer, is controversial. We examined associations between low-dose aspirin, statins, NSAIDs, and metformin with BTC risk.

Methods: We used a population-based cohort of 5.

The Natural History of Chronic Unexplained Gastrointestinal Disorders and Gastroesophageal Reflux During 20 Years: A US Population-Based Study.

Objective: To explore the natural history of chronic unexplained gastrointestinal (GI) symptoms and to determine the longitudinal trends of prevalence during a 20-year period in a single US community.

Methods: Between January 1, 1990, and December 31, 2009, valid self-report questionnaires of GI symptoms were mailed to randomly selected cohorts of a community. The study used respondents who answered questions on 1 or more of 3 surveys (initial, 1990-1992; second, 2003-2004; and third, 2008-2009).

The relationship between learner engagement and teaching effectiveness: a novel assessment of student engagement in continuing medical education.

Background: Continuing medical education (CME) often uses passive educational models including lectures. However, numerous studies have questioned the effectiveness of these less engaging educational strategies. Studies outside of CME suggest that engaged learning is associated with improved educational outcomes.

Cost analysis and complication profile of primary shoulder arthroplasty at a high-volume institution.

Background: Paralleling the increased utilization of shoulder arthroplasty, bundled-payment reimbursement is becoming increasingly common. An understanding of the costs of each element of care and detailed information on the frequency of and reasons for readmission and reoperation are keys to developing bundled-payment initiatives. The purpose of this study was to perform a comprehensive analysis of complications, readmission rates, and costs of primary shoulder arthroplasty at a high-volume institution.
