BACKGROUND: Medical missions to low and middle-income countries are increasingly frequent, with an estimated 6,000 trips sponsored by U.S. organizations accounting for approximately 200,000 surgical cases and $250 million in costs annually. However, these missions have received little critical evaluation. This paper describes the research program Operation Walk (Op-Walk) Boston, and proposes an evaluation model for similar surgical missions. METHODS: We propose an evaluation model, borrowing from the work of Donabedian and enriched by evidence from our research program...

Schistosomiasis is still a public health problem in Brazil. The Kato-Katz test is the most frequently used diagnostic method for Schistosoma mansoni infection. However, it lacks sensitivity in areas of low prevalence. We have assessed the positivity rate of S. mansoni infection in Bananeiras, a village on Capistrano, Ceara, Brazil by performing a point-of-care test in urine to determine the circulating cathodic antigens (POC-CCA), and we compared the findings with those of the Kato-Katz technique for egg detection in stool and an enzyme-linked immunosorbent assay for specific antibodies against adult worms (SWAP-ELISA) in serum before treatment (baseline)...

BACKGROUND: Recent studies have reported successful arteriovenous (AV) fistula maturation rates between 40% and 80%, with older age, distal fistula location, and small vein diameter associated with greater failure rates. Our objective is to determine if these findings are consistent with the outcomes at our institution. METHODS: A retrospective chart review was performed on patients who underwent upper extremity AV fistula creation at a single institution. Patient demographics and risk factors were analyzed, as well as fistula location and vein diameter based on pre-operative ultrasound...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is an increasingly common treatment of symptomatic severe aortic valve stenosis (AS). Thus, it is reasonable to carefully investigate the impact of individual clinical factors on outcomes after TAVI. OBJECTIVES: We aimed to investigate the impact of the previous cerebro-vascular events (CVEs) on outcomes of patients with severe AS undergoing TAVI. METHODS: A total of 148 consecutive patients scheduled for TAVI were included and stratified as with and without a history of CVEs (stroke or transient ischemic attack)...

Society of Thoracic Surgeons (STS) score and frailty index are calculated routinely as part of transcatheter aortic valve implantation (TAVI) assessment to determine procedure risk. We aim to evaluate the incremental improvement of STS risk score using frailty status in predicting short- and long-term outcome after TAVI. Study population included 544 consecutive TAVI patients who completed full frailty assessment and STS score calculation before the procedure. Frailty is defined by the presence of any 3 of the following 5 criteria: algorithm-defined grip strength and 15-foot walking tests, body mass index < 20 kg/m2, Katz activity of daily living ≤ 4/6, serum albumin < 3...

Introduction: Among veterans of post-9/11 conflicts, estimates of post-traumatic stress disorder (PTSD) range from 9% shortly after returning from deployment to 31% a year after deployment. Clinical and pharmaceutically based treatments are underutilized. This could be due to concerns related to lost duty days, as well as PTSD patients' fears of stigma of having a mental health condition. Yoga has been shown to reduce PTSD symptoms in the civilian population, but few studies have tested the impact of yoga on veterans of post-9/11 conflicts...

BACKGROUND: Schistosomiasis in the People's Republic of China (PRC) can be traced back to antiquity. In the past 60 years, the Chinese government has made great efforts to control this persistent disease with elimination slated by 2020 through the implementation of a comprehensive control strategy. This strategy aims to reduce the role of bovines and humans as sources of infection as a pre-requisite for elimination through transmission interruption. The goal of elimination will be achievable only by the implementation of a sustainable surveillance and control system, with sensitive diagnosis a key feature so that the true disease burden is not underestimated...
