Background: Virtual reality (VR) has been established as a valuable tool outside of medicine but there has been limited uptake in orthopaedics despite being a specialty heavily dependent on psychomotor skills. The purpose of this study was to assess the feasibility of setting up an on-site virtual reality surgical training hub for an orthopaedic surgery unit. A secondary objective was to document encountered hurdles to assist other institutions with a similar process. Methods: The study explored the logistical and organizational considerations in the process of creating a virtual reality training area. This included: review of location, set up management, funding arrangements, set up time, research opportunities and training time. Set up and completion times were recorded during a separate trial of 24 participants ranging from medical students to senior consultant orthopaedic surgeons. Results: A VR training area was successfully established over a period of 3 months. A dedicated area for training where the equipment remains permanently was designated to facilitate ease of use. Average set up took 7.5 min to turn the computer on and 25 min for the participants to start the module. Issues identified during set up were recorded. Conclusions:The study demonstrated that it is possible to set up a dedicated area for virtual reality surgical training within a hospital unit. A dedicated lockable area is the most feasible method of establishing such a space and reduces the requirement to recalibrate and transfer equipment around the hospital.
Background Vedolizumab blocks inflammatory activity within the gastrointestinal tract. Systematic reviews have demonstrated the efficacy of vedolizumab in ulcerative colitis and inflammatory bowel disease in general. This systematic review and meta‐analysis summarises the current evidence of vedolizumab in the induction and maintenance of remission in Crohn's disease. Objectives To evaluate the benefits and harms of vedolizumab versus placebo for the induction and maintenance of remission in people with Crohn's disease. Search methods We used standard, extensive Cochrane search methods. The latest search date was 30 November 2022. Selection criteria We included randomised controlled trials (RCTs) and quasi‐RCTs comparing vedolizumab to placebo for the induction or maintenance of remission in people with Crohn's disease. Data collection and analysis We used standard Cochrane methods. For induction studies, the primary outcome was 1. clinical remission, and secondary outcomes were rates of 2. clinical response, 3. adverse events, 4. serious adverse events, 5. surgery, 6. endoscopic remission and 7. endoscopic response. For maintenance studies, the primary outcome was 1. maintenance of clinical remission, and secondary outcomes were rates of 2. adverse events, 3. serious adverse events, 4. surgery, 5. endoscopic remission and 6. endoscopic response. We used GRADE to assess certainty of evidence. Main results We analysed induction (4 trials, 1126 participants) and maintenance (3 trials, 894 participants) studies representing people across North America, Europe, Asia and Australasia separately. One maintenance trial administered subcutaneous vedolizumab whilst the other studies used the intravenous form. The mean age ranged between 32.6 and 38.6 years. Vedolizumab was superior to placebo for the induction of clinical remission (71 more per 1000 with clinical remission with vedolizumab; risk ratio (RR) 1.61, 95% confidence interval (CI) 1.20 to 2.17; number needed to treat for an additional beneficial outcome (NNTB) 13; 4 studies; high‐certainty evidence) and superior to placebo for inducing clinical response (105 more per 1000 with clinical response with vedolizumab; RR 1.43, 95% CI 1.19 to 1.71; NNTB 8; 4 studies; high‐certainty evidence). For the induction phase, vedolizumab may be equivalent to placebo for the development of serious adverse events (9 fewer serious adverse events per 1000 with vedolizumab; RR 0.91, 95% CI 0.62 to 1.33; 4 studies; low‐certainty evidence) and probably equivalent to placebo for overall adverse events (6 fewer adverse events per 1000 with vedolizumab; RR 1.01, 95% CI 0.93 to 1.11; 4 studies; moderate‐certainty evidence). Vedolizumab was superior to placebo for the maintenance of clinical remission (141 more per 1000 with maintenance of clinical remission with vedolizumab; RR 1.52, 95...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
