The reliability of functional tests used in remote assessment is limited in patients with chronic stroke. The aim of the study was to assess the inter-reliability of the Berg balance scale, the timed-up and go test, and the box and block test via remote assessment, in patients with chronic stroke.\u0000Methods: Fifteen patients (8 men and 7 women) underwent a home-based teleassessment using a software platform and a center-based face-to-face assessment, on two consecutive days. The assessment order was randomized and conducted by an independent examiner. All participants were instructed regarding the use of the software platform, home equipment preparation, and safety issues\u0000Results: Participants aged 50-70 years (mean 59.6±7.34) with an average of 4.8±2.5 years after stroke and a moderate degree of motor dependence (Barthel scale: mean 83±8.61 units) completed all tests in both assessment procedures without experiencing adverse events. The inter-reliability was moderate for the total BBS score: ICC=0.869 (95% CI: 0.616 to 0.955), excellent for the total time of the TUG: ICC=0.968 (95% CI: 0.907 to 0.989) as well as for the upper right and left arm scores of the BBT: ICC=0.974 (95% CI: 0.922 to 0.991) and ICC=0.966 (95% CI: 0.897 to 0.988), respectively.\u0000Conclusions: Tele-assessment for BBS, TUG, and BBT appears moderate to excellent inter-reliability in functionally independent patients with chronic stroke.","PeriodicalId":13787,"journal":{"name":"International Journal of Clinical Trials","volume":"41 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140662934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Point-of-Care Ultrasound (POCUS) offers a radiation-free alternative and, specifically the pocket-size variant, enhances convenience at the patient's bedside. While evidence supports ultrasound's accuracy in detecting community-acquired pneumonia (CAP) in children comparable to CXR, few studies have explored its ability to distinguish pneumonia etiology, especially utilizing pocket-size POCUS devices.\u0000Methods: In this prospective diagnostic cohort study conducted over a year in a tertiary pediatric referral center, we aim to assess the diagnostic accuracy of a pocket-size POCUS device compared to CXR for determining the etiology of CAP in pediatric patients (aged >6 months and <18 years). At least 76 participants diagnosed with CAP will undergo independent POCUS examinations at various intervals, complemented by CXRs when necessary, independently classified by a third investigator. The General Electrics Vscan AirTM®, featuring Bluetooth connectivity to smartphone/tablet, will be employed for POCUS. Data collection will include systematized POCUS and CXR descriptions, alongside sociodemographic, clinical, and therapeutic variables. Statistical analysis using SPSS® version 28 will evaluate the diagnostic accuracy of the POCUS device.\u0000Conclusions: This trial's outcomes hold significant promise in unveiling unknown data about the diagnostic accuracy of pocket-size POCUS for pediatric CAP etiological diagnosis. Utilizing a device meeting technical recommendations, featuring a dual-headed probe and Bluetooth connectivity, this study has the potential to bring innovation to clinical practice, improving patient care and creating scientific value.\u0000Trial Registration Number: NCT06296693.","PeriodicalId":13787,"journal":{"name":"International Journal of Clinical Trials","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140664994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A typical example of the challenges in conducting clinical trial studies was where Ghana was selected to conduct the ebola vaccine trials, which was not successful. This study explored the social and political perspectives on the unsuccessful implementation of the ebola vaccine trial in Ghana.\u0000Methods: This was a cross-sectional exploratory study using qualitative research approach where 31 in-depth individual interviews and Key informant interviews were conducted with participants. The interviews were recorded, transcribed and coded into themes using Nvivo 12 software to aid thematic content analysis.\u0000Results: The views expressed by participants suggested that lack of stakeholder engagement to create awareness on the Ebola vaccine trial led to doubts on the purpose for the trial. Also, media propaganda, negative influence and the perception that conducting the vaccine trial in Ghana could introduce the Ebola virus into the country created panic and fear, which affected public trust and support for the Ebola vaccine trial conduct in Ghana. Furthermore, political influence linked with site selection and timing for the study in particular, led to mistrust and the subsequent suspension of the trial in Ghana.\u0000Conclusions: Based on the interpretation of our data, we conclude that the indefinite suspension of the Ebola vaccine trial in Ghana could largely be attributed to both fear and political influence as well as misinformation resulting from media propaganda leading to mistrust.","PeriodicalId":13787,"journal":{"name":"International Journal of Clinical Trials","volume":"19 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140660455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The impact on endurance-trained young cross-country skiers (XCS) with elevated bone turnover remains unclear. Purpose of study was to estimate the optimal daily efficacy dose of Jarlsberg cheese to increase serum Osteocalcin level in young female and male XCS and estimate the Jarlsberg effect on bone turnover markers (BTMs) and bone mineral density (BMD).\u0000Methods: In a parallel group study consisting of three design levels, 10 female and 10 male XCS were included, using Response Surface Pathway design. Blood samples were taken at each level for measurements of Osteocalcin, vitamin K2, BTMs and other biochemical parameters. Resting metabolic rate (RMR), BMD, VO2max and muscle strength were measured at start and at the end of the study.\u0000Results: The Osteocalcin development with increasing dose of Jarlsberg cheese was almost parallel in both sexes. These variables were reduced significantly from baseline during the first two design levels but increased above baseline by the end of the study. BTMs decreased significantly during the first and second level but increased during the third level. Total and L1-L4 BMD, s-phosphate, s-urea, RMR, muscle strength and Peak VO2 increased significantly while s-calcium and s-magnesium decreased.\u0000Conclusions: Estimated OED of Jarlsberg cheese was 73 and 84 g/day for females and male athletes, respectively. The development in OC, BTMs and BMD suggest an antiresorptive and perhaps anabolic effect of Jarlsberg Cheese on bone tissue. VO2 max, RMR and muscular strength development indicated an anabolic situation.","PeriodicalId":13787,"journal":{"name":"International Journal of Clinical Trials","volume":"65 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140665267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The introduction of new, combustion-free nicotine and tobacco products extended the tool kit for people who smoke to switch away from their risky habit. We performed a systematic review including 120 studies resulting in several recommendations for a robust study design to determine the cessation efficacy of a new nicotine or tobacco product. Consequently, we prepared this study protocol to assess the cessation efficacy of heated tobacco products (HTPs) and nicotine pouches (NPs).\u0000Methods: 250 subjects (125 exclusive smokers and 125 exclusive smokeless tobacco (SLT) users) will be recruited and offered a choice of HTPs in case of smokers and a choice of NPs in case of SLT users in order to switch. Subjects will undergo four visits (baseline, 1, 3, and 6 months) to collect biospecimens and for physical examinations. Use behaviour and questionnaires will be monitored on a regular basis by means of a smartphone-app. We describe a sensitive and specific compliance monitoring using suitable biomarkers of exposure. The sample size of 250 subjects and duration of 6 months will allow the quit rates to be assessed with sufficient statistical power.
