Impact of Clinical Trial Enrollment on Thrombolysis Workflow in a Mobile Stroke Unit: Results from the AcT Trial.

Background: The Edmonton-based mobile stroke unit (MSU), which transports patients to the University of Alberta Hospital (UAH), enrolled patients in the Intravenous Tenecteplase Compared with Alteplase for Acute Ischemic Stroke (AcT) trial. We examined the feasibility of trial enrollment in MSU, its impact on acute stroke workflow metrics and functional outcomes at 90-120 days.

Methods: In this post hoc analysis, patients were divided into three groups based on enrollment site: MSU ( = 43), UAH ( = 273) and non-UAH ( = 1261).

Intersection of Performance, Interpretability, and Fairness in Neural Prototype Tree for Chest X-Ray Pathology Detection: Algorithm Development and Validation Study.

Background: While deep learning classifiers have shown remarkable results in detecting chest X-ray (CXR) pathologies, their adoption in clinical settings is often hampered by the lack of transparency. To bridge this gap, this study introduces the neural prototype tree (NPT), an interpretable image classifier that combines the diagnostic capability of deep learning models and the interpretability of the decision tree for CXR pathology detection.

Objective: This study aimed to investigate the utility of the NPT classifier in 3 dimensions, including performance, interpretability, and fairness, and subsequently examined the complex interaction between these dimensions.

Prospective surveillance and early intervention to prevent chronic breast cancer-related arm lymphedema-what are the barriers?

Up to one in five early breast cancer patients develop chronic upper limb lymphedema after breast cancer treatments. This treatment complication is irreversible and can significantly impact the quality of life of breast cancer survivors. The model of prospective surveillance and early intervention has emerged as a potential strategy to prevent the development of this debilitating treatment-related complication.

Automatic Matching Algorithms to Identify Eligible Participants for Stroke Trials: A Proof-of-Concept Study.

Background: Clinical trials often struggle to recruit enough participants, with only 10% of eligible patients enrolling. This is concerning for conditions like stroke, where timely decision-making is crucial. Frontline clinicians typically screen patients manually, but this approach can be overwhelming and lead to many eligible patients being overlooked.

Exploring the Perspectives of Older Adults Living With HIV on Virtual Care: Qualitative Study.

Background: As the population of individuals with HIV ages rapidly due to advancements in antiretroviral therapy, virtual care has become an increasingly vital component in managing their complex health needs. However, little is known about perceptions of virtual care among older adults living with HIV.

Objective: This study aimed to understand the perceptions of older adults living with HIV regarding virtual care.

Effect of omalizumab on inflammatory markers in COVID-19: an exploratory analysis of the COVID-19 immunologic antiviral therapy with omalizumab (CIAO) trial.

Background: The CIAO trial recently demonstrated a probable clinical benefit of omalizumab in the treatment of severe COVID-19; however, the mechanism underlying this benefit remains unclear. Therefore, we sought to longitudinally assess the impact of omalizumab on serum cytokines in CIAO trial patients to determine its mechanism of action.

Methods: Blood samples were collected on days 0, 2, 7, and 14 from patients recruited into the CIAO trial and who consented to this substudy.

Relationship Between Social Deprivation and Access to Catheter Ablation for Atrial Fibrillation: A Population-Level Study.

Background: Access to catheter ablation for atrial fibrillation (AF) may vary due to social deprivation.

Objectives: This study sought to characterize the correlation between our outcomes of interest (rates of AF diagnoses, ablation referrals, and procedures) and the association between social deprivation and our outcomes.

Methods: Rates and correlations of AF diagnoses, ablation referrals, and procedures were reported across 49 census divisions in Ontario, Canada.

Feasibility of a Yoga Intervention in an Inpatient Limb Loss Rehabilitation Program.

Background: Limb loss is a life-changing event, which may be associated with limited mobility, pain, and low mood. Yoga interventions have been found to be beneficial for improving emotional wellness and pain in other patient populations. The benefits of including yoga in limb loss rehabilitation have not been well studied.

Comparison of a SARS-CoV-2 mRNA booster immunization containing additional antigens to a spike-based mRNA vaccine against Omicron BA.5 infection in hACE2 mice.

The emergence of SARS-CoV-2 variants presents challenges to vaccine effectiveness, underlining the necessity for next-generation vaccines with multiple antigens beyond the spike protein. Here, we investigated a multiantigenic booster containing spike and a chimeric construct composed of nucleoprotein (N) and membrane (M) proteins, comparing its efficacy to a spike-only booster against Omicron BA.5 in K18-hACE2 mice.

PNEUMATIC RETINOPEXY FOR GIANT RETINAL TEAR ASSOCIATED RETINAL DETACHMENT: A Retrospective Cohort Study.

Purpose: To report the technique and long-term outcomes of patients with giant retinal tear associated retinal detachment (GRT-RD) treated with pneumatic retinopexy (PnR).

Methods: Retrospective cohort study. All patients presenting with GRT-RD with tears in the superior ten-clock hours who underwent primary PnR were included in this study.

Family perspectives on physical restraint practices and minimization in an adult intensive care unit: A qualitative descriptive study.

Objective: To explore family perspectives on physical restraint practices and their minimization in an adult intensive care unit.

Design & Methods: A qualitative descriptive study with one-on-one semi-structured interviews. A deductive content analysis approach was undertaken using the Theoretical Domains Framework.

Validation of Prognostic Models for Renal Cell Carcinoma Recurrence, Cancer-Specific Mortality, and All-Cause Mortality.

Purpose: Postoperative prognostic tools allow for improved prediction of future recurrence risk, patient counseling, and assessment of eligibility for adjuvant treatments and ensure appropriate follow-up surveillance. The purpose of this analysis was to validate existing prognostic models for patients with kidney cancer.

Materials And Methods: The Canadian Kidney Cancer information system is a prospective cohort of patients managed at 14 institutions since January 1, 2011, to present.

Mindfulness in Surgical Training (MiST): A Modified Mindfulness Curriculum for Surgical Residents.

Objectives: Residents experience numerous work-related and personal stressors that make it difficult to focus in the operating room, negatively impacting learning and surgical performance. Mindfulness-based cognitive therapy decreases anxiety and improves memory and learning. This study aimed to create a feasible and desirable modified mindfulness curriculum for surgical residents.

Characteristics, progression, management, and outcomes of NEC: a retrospective cohort study.

Background: Necrotising enterocolitis (NEC) in preterm infants is associated with high morbidity and mortality. In most neonates, it is a progressive disease from medical NEC (mNEC) to surgical NEC (sNEC); however, in some, it presents as sNEC from onset.

Objective: To evaluate the rate, the timing of progression, different surgical approaches, and outcomes of mNEC and sNEC in preterm neonates.
