An Environmental Scan of Canadian Kidney Transplant Programs for the Management of Patients With Graft Failure: A Research Letter.

Background: Kidney transplant recipients with graft failure (KTR-GF) and those with a failing graft are an increasingly prevalent group of patients. Their clinical management is complex, and outcomes are worse than transplant naïve patients on dialysis. In 2023, the Kidney Disease: Improving Global Outcomes (KDIGO) organization reported findings from a controversies conference and identified several clinical practice priorities for KTR-GF.

MultiNet 2.0: A lightweight attention-based deep learning network for stenosis measurement in carotid ultrasound scans and cardiovascular risk assessment.

Background: Cardiovascular diseases (CVD) cause 19 million fatalities each year and cost nations billions of dollars. Surrogate biomarkers are established methods for CVD risk stratification; however, manual inspection is costly, cumbersome, and error-prone. The contemporary artificial intelligence (AI) tools for segmentation and risk prediction, including older deep learning (DL) networks employ simple merge connections which may result in semantic loss of information and hence low in accuracy.

Aerobic Physical Activity and Depression Among Patients With Cancer: A Systematic Review and Meta-Analysis.

Importance: Depression is prevalent among patients with cancer, affecting their quality of life and survival. Aerobic physical activity (APA) is an effective strategy for managing depression in the general population, but its effectiveness for reducing depressive symptoms among patients with cancer requires further study.

Objective: To evaluate whether APA decreases depression severity in patients with cancer by synthesizing data from published randomized clinical trials (RCTs).

Pathways to cancer care after a suspected cancer diagnosis in the emergency department: a survey of emergency physicians across Ontario.

Introduction: Little is known about how patients are managed after a suspected cancer diagnosis through the emergency department. The objective of this study was to examine the ED management, specifically referral practices, for ten suspected cancer diagnoses by emergency physicians across Ontario and to explore variability in management by cancer-type and centre.

Methods: An electronic survey was distributed to emergency physicians across Ontario, asking about referral practices for patients who could be discharged from the ED with one of ten suspected cancer diagnoses.

The Australian Frailty Network: Development of a consumer-focussed national response to frailty.

Frailty is an important concept in the care of older adults. Over the past two decades, significant advances have been made in measuring frailty. While it is now well-recognised that frailty status is an important determinant of outcomes from medical illnesses or surgical interventions, frailty measurement is not currently routinely integrated into clinical practice.

Characterizing usual-care physical rehabilitation in Canadian intensive care unit patients: a secondary analysis of the Canadian multicentre Critical Care Cycling to Improve Lower Extremity Strength pilot randomized controlled trial.

Purpose: Physical rehabilitation (PR) in the intensive care unit (ICU) may improve outcomes for survivors but clinical trial results have been discordant. We hypothesized that discordant results may reflect treatment heterogeneity received by "usual care" comparator groups in PR studies. Usual-care PR is typically underspecified, which is a barrier to comparing results across treatment studies.

Identifying serious underlying diagnoses among patients with brief resolved unexplained events (BRUEs): a Canadian cohort study.

Objective: To describe the demographics and clinical outcomes of infants with brief resolved unexplained events (BRUE).

Design: A retrospective cohort study.

Setting: 11 centres within the Canadian Paediatric Inpatient Research Network.

Diabetes mellitus is associated with low exercise capacity and impaired peripheral vasodilation in patients with heart failure - a propensity score-matched study.

Aims: Diabetes mellitus (DM) and heart failure (HF) share vascular, skeletal and metabolic abnormalities that can reduce exercise capacity. We investigated whether exercise capacity differ in patients with type 2 DM compared to those without DM with HF of similar severity.

Methods And Results: The Studies Investigating Co-morbidities Aggravating HF (SICA-HF) prospectively enrolled 615 patients with chronic HF, 259 (42.

Intra- and post-procedural patient-reported experience measures and their correlation with post-ERCP adverse events and unplanned healthcare utilization.

Background:  Post-endoscopic retrograde cholangiopancreatography (ERCP) adverse events (AEs) are common, as is unplanned healthcare utilization (UHU). We aimed to assess potential etiologic associations between intra-/post-procedural patient-reported experience measures (PREMs) and post-ERCP AEs and UHU. METHODS : Prospective data from a multicenter collaborative were used.

Testing of rapid evaporative mass spectrometry for histological tissue classification and molecular diagnostics in a multi-site study.

Background: While REIMS technology has successfully been demonstrated for the histological identification of ex-vivo breast tumor tissues, questions regarding the robustness of the approach and the possibility of tumor molecular diagnostics still remain unanswered. In the current study, we set out to determine whether it is possible to acquire cross-comparable REIMS datasets at multiple sites for the identification of breast tumors and subtypes.

Methods: A consortium of four sites with three of them having access to fresh surgical tissue samples performed tissue analysis using identical REIMS setups and protocols.

Impact of Tourniquet Use in Major Lower Limb Amputation: A Systematic Review and Meta-analysis.

Objective: Intra-operative blood loss is a significant complication of major lower limb amputation (MLLA). This systematic review and meta-analysis assessed the effect of tourniquet use on patients undergoing amputation.

Data Sources: Embase, MEDLINE, and Cochrane databases were searched from inception to April 2024.

Emergency admission predictive risk stratification models: assessment of implementation consequences (PRISMATIC 2): protocol for a mixed methods study.

Background: Emergency admissions are costly, increasingly numerous, and associated with adverse patient outcomes. Policy responses have included the widespread introduction of emergency admission risk stratification (EARS) tools in primary care. These tools generate scores that predict patients' risk of emergency hospital admission and can be used to support targeted approaches to improve care and reduce admissions.

Increased Mortality in a Nationwide Study of Gastrointestinal Hospitalizations in the United States During the 2020 Coronavirus Pandemic.

Background The impact of the coronavirus disease-2019 (COVID-19) pandemic on patients with acute gastrointestinal (GI) presentations including acute pancreatitis, diverticulitis, and GI bleeding, requiring hospitalization, has not been fully characterized at the population level in the United States. Aims We used the National Inpatient Sample to describe inpatient gastroenterology outcomes in the United States during the first year of the pandemic (2020), using 2018 and 2019 as comparator years. Methods Using the National Inpatient Sample, we explored year-to-year and month-to-month trends in hospitalizations, length of stay, and inpatient mortality for GI presentations, including luminal, biliary, infectious, inflammatory, and pancreatic diseases, with regression modeling.

A randomized trial of ibrutinib and R-GDP prior to stem cell transplant in relapsed diffuse large B-cell lymphoma.

In the LY.17 randomized phase II clinical trial, adults with relapsed and refractory diffuse large B-cell lymphoma treated with ibrutinib-R-GDP (IR-GDP) for up to three cycles had more documented bacterial and fungal infections, without improvement in overall response, compared with R-GDP. CR, complete response; DLBCL, diffuse large B-cell lymphoma; PD, progressive disease; PR, partial response; R/R, relapsed/refractory; SD, stable disease.

Clinical and genetic delineation of autosomal recessive and dominant ACTL6B-related developmental brain disorders.

Purpose: This study aims to comprehensively delineate the phenotypic spectrum of ACTL6B-related disorders, previously associated with both autosomal recessive and autosomal dominant neurodevelopmental disorders. Molecularly, the role of the nucleolar protein ACTL6B in contributing to the disease has remained unclear.

Methods: We identified 105 affected individuals, including 39 previously reported cases, and systematically analysed detailed clinical and genetic data for all individuals.
