Background: The International Committee of Medical Journal Editors (ICMJE) recommends that trial authors must specify data sharing plans when trials are registered and published, yet this uptake remains unclear. We aimed to assess the practice of data sharing plans in trial registration platforms and the concordance between registered and published data sharing plans.

Methods: We included clinical trials published between 2021 and 2023 in six high-profile journals (The Lancet, The New England Journal of Medicine, JAMA, BMJ, JAMA Internal Medicine, and Annals of Internal Medicine) that enrolled participants no earlier than 2019 and registered on clinical trial platforms.

Prognostication of neurodevelopmental outcomes for neonates with hypoxic-ischemic encephalopathy (HIE) is primarily reliant on structural assessment using conventional brain magnetic resonance imaging in the clinical setting. Diffuse optical tomography (DOT) can provide complementary information on brain function at the bedside, further enhancing prognostic accuracy. The predictive accuracy and generalizability of DOT-based neuroimaging markers are unknown.

The purpose of this study was to determine the feasibility (recruitment, retention, and adherence rates) and effectiveness of institution-based exercise and self-management (SM) on physical activity (PA) level, exercise knowledge and intention, health status, functional capacity, patient engagement, and lower extremity strength for individuals with breast cancer receiving treatment. We conducted a hybrid implementation-effectiveness trial (type 1), including female participants with a current diagnosis of breast cancer undergoing treatment. Participants were randomized to (1) exercise and SM (EXSM; 8 in person exercise sessions and SM education), (2) SM only (8 sessions of SM), or (3) usual care (UC; no intervention).

Many cardiovascular disease (CVD) journals request data sharing statements upon trial report submission, but their compliance in publishing these statements remains unclear. We therefore performed a quantitative analysis to evaluate the current practice of the publications of data sharing statements in clinical trials by CVD journals, which included 78 CVD journals that published clinical trials from Jan 2019 to Dec 2022 and had data sharing statement request. Multivariable logistic regression analysis was used to examine the association between journal characteristics and journals' publications of statements.

Background: Skin antisepsis remains a vital component in prophylaxis against surgical site infection (SSI); however, for open fractures, it is unclear whether alcohol-based or aqueous solutions should be preferred. The purpose of this study was to compare the use of alcohol-based and aqueous skin antisepsis solutions, using data from the 2 PREP-IT trials, with respect to the risks of SSI and unplanned reoperation following surgery for an open fracture.

Methods: Individual patient data from the 2 cluster-randomized, crossover clinical trials were combined to create a single data set of patients undergoing surgery for an open fracture.

Background: Multimorbidity, the presence of two or more (2+) chronic conditions, presents significant challenges for healthcare delivery, particularly among populations with opioid use disorder (OUD). Multimorbidity patterns among individuals with OUD are not well established, and minimal research exists examining the impact of clustering methods on identifying these patterns.

Objective: Our study aimed to assess multimorbidity prevalence, explore associated sociodemographic and clinical characteristics, and determine multimorbidity patterns using hierarchical cluster analysis (HCA) and K-means clustering among people receiving treatment for OUD in Ontario, Canada between 2011 and 2021.

Background: Coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) continues to have a significant impact worldwide, in part due to a reduction in neutralising antibody protection provided by vaccines targeting monovalent spike antigens related to immune escape. Development of vaccines amenable for respiratory mucosal delivery that provide broad and durable immunity are needed. This study aims to determine the safety and immunogenicity of a single inhaled dose of a replication-deficient chimpanzee adenovirus type 68 vector expressing a trivalent transgene cassette of SARS-CoV-2 S1 domain of spike, nucleocapsid and RNA polymerase genes (ChAd-triCoV/Mac).
