However, determining the optimal tourniquet inflation pressure is a topic of debate. The current approach involves using a constant tourniquet pressure, although this is associated with the potential to augment the risk of tourniquet-associated complications. The Association of Surgical Technologists recommends a tourniquet pressure of systolic blood pressure plus 50 mm Hg for the upper limb and 100 mm Hg for the lower limb. Nevertheless, this method lacks robust support from high-quality medical literature. Therefore, the study aimed to compare the hemostatic efficacy and disparities in tourniquet pressure settings based on systolic blood pressure versus those using the constant-pressure method. The findings might outline the theoretical framework necessary for advocating for tourniquet pressure setups guided by systolic blood pressure.</div></div><div><h3>Methods/design</h3><div>This randomized controlled study classified the tourniquet pressure regimen into two groups: one based on the patient's systolic blood pressure (the study group) and the other using a constant pressure (the control group). The study included patients aged between 16 and 70 who presented with fresh fractures (less than 3 weeks) of the lower and upper limbs. All the included patients required surgical treatment involving the intraoperative use of a tourniquet and had no contraindications to this surgery. Our primary outcome was to assess the surgeon's satisfaction with the hemostasis achieved in the operative field. We also examined the changes in the circumference of the limb where the tourniquet was applied and tracked any postoperative complications and their incidence. The study ultimately encompassed 144 patients.</div></div><div><h3>Discussion</h3><div>Despite the prevalent use of tourniquets in surgical operations related to limb fractures, conflicting viewpoints persist concerning the adjustments in pressure and other elements. The study aimed to compare the hemostatic efficacy and disparities in tourniquet pressure settings based on systolic blood pressure versus those using the constant-pressure method.</div></div><div><h3>Study registration</h3><div>The study was duly recorded in the Chinese Clinical Trial Registry on May 13, 2022 (Registration number: ChiCTR2200059867).</div></div><div><h3>Registration website</h3><div><span><span>https://www.chictr.org.cn/showproj.aspx?proj=162504</span><svg><path></path></svg></span>.</div></div>","PeriodicalId":37937,"journal":{"name":"Contemporary Clinical Trials Communications","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142572638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the construction and interpretation of these function forms are quite different, this study aims to provide detailed discussions and comprehensive comparisons on the design and testing approach for RD and OR scales for the fixed and group sequential three-arm NI trials under various of situations. The sample size determinations and testing approaches for assessing NI of a new treatment in three-arm clinical trials for RD and OR scales were reviewed comprehensively. Simulation studies are conducted for hundreds of scenarios with parameter configurations of the response rates, randomized allocations, NI margins and interim analysis. The operating characteristic (OC) of RD and OR scales based on the MLE and RMLE methods were thoroughly investigated. A trial example was designed and analyzed to demonstrate the methodologies. It is found that sample size determination on OR scale gives smaller sample size and robust procedure compared to RD scale in the majority of situations. When evaluating the behaviors of the attained power, the RMLE methods based on OR scale outperforms the MLE method and tend to have more power to reject the null hypothesis especially under the small sample size situations. Compared to the fixed design, the group sequential design has better OC, which provides a comparable power while needing smaller total average sample sizes for all cases. In addition, we suggest a lower significance level with a higher power for the sample size determination in the superiority test stage in the group sequential design, which can significantly reduce the total sample sizes while the number of subjects in the placebo group does not increase much. It can offer some recommendations for the investigators to choose the optimal endpoints and parameter configurations to design a three-arm NI trial under certain situations.</div></div>","PeriodicalId":37937,"journal":{"name":"Contemporary Clinical Trials Communications","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142526903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A key limitation to these services is the job interview component, which relies on non-standardized, resource-intensive, staff-led role-plays to help autistic transition-age youth improve their interview skills. The autism community has called for better job interview preparation. To address this gap in services, our team, collaborated with the autism community to adapt the intervention, Virtual Reality Job Interview Training (<em>VR-JIT</em>; effective among adults with serious mental illness), into Virtual Interview Training for Transition Age Youth (<em>VIT-TAY</em>). This adapted intervention was tailored to meet the needs of autistic transition age youth while maintaining the core components of <em>VR-JIT</em> (i.e., an online job interview simulator with four levels of automated feedback and e-learning content). A pilot randomized controlled trial (RCT) demonstrated <em>VIT-TAY</em>'s feasibility and initial effectiveness at improving job interview skills, reducing anxiety, and increasing employment rates within six months when added to transition services or pre-employment transition services (Pre-ETS). Thus, the overarching goal of this Hybrid Type 1 effectiveness-implementation study protocol is to conduct a fully-powered RCT of VIT-TAY across 16 schools in various geographical locations. Our specific aims are to 1) Evaluate whether Pre-ETS (or transition services) with <em>VIT-TAY</em>, as compared to Pre-ETS (or transition services) with an active control intervention (i.e., job interview didactics/e-learning with a series of 3–5 min videos of employed autistic adults talking about their career pathways) enhances employment outcomes; 2) Evaluate mechanisms of employment by nine months post-randomization; and 3) Conduct a multilevel, mixed-method process evaluation of the initial implementation of <em>VIT-TAY</em> across settings (e.g., acceptability, feasibility, and barriers and facilitators of implementation).</div></div>","PeriodicalId":37937,"journal":{"name":"Contemporary Clinical Trials Communications","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142526904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
