Crowd-sourcing social computing systems represent a new material for HCI designers. However, these are difficult to work with and prototype, because they require critical mass of participants investigate behavior. Service design is an emerging research area that focuses on how customers co-produce the services use, thus it appears be great domain apply this material. To relationship, we developed Tiramisu, transit information system where commuters share GPS traces submit problem reports....

Objective Weight loss interventions to treat obesity include sleeve gastrectomy (SG), lifestyle intervention (LI), endoscopic gastroplasty (ESG) and semaglutide. We aimed identify which treatments are cost-effective requirements for semaglutide be cost-effective. Design developed a semi-Markov microsimulation model compare the effectiveness of SG, ESG, LI weight in 40 years old with class I/II/III obesity. Extensive one-way sensitivity threshold analysis were performed vary cost treatment...

Greater availability of less invasive biliary imaging to rule out choledocholithiasis should reduce the need for diagnostic endoscopic retrograde cholangiopancreatography (ERCP) in patients who have a remote history cholecystectomy. The primary aims were determine incidence, characteristics, and outcomes individuals undergo first-time ERCP >1 year after cholecystectomy (late-ERCP).

There is significant research interest in developing and validating novel pancreatic cyst-fluid biomarkers given the increasing recognition of prevalence cysts their associated malignant potential. Although current international consensus guidelines are helpful, they fail to diagnose with certainty cyst type level epithelial dysplasia. They also fall short predicting future likelihood transformation. A systematic review was performed objective summarizing cyst-fluid-based that have been...

The use of computer-aided detection (CADe) has increased the adenoma rates (ADRs) during colorectal cancer (CRC) screening/surveillance in randomized controlled trials (RCTs) but not shown benefit real-world implementation studies. We performed a single-center pragmatic RCT to evaluate impact real-time CADe on ADRs colonoscopy by community gastroenterologists.
