External Validation of SHAPE Score: A Score to Predict Low-Risk Lower Gastrointestinal Bleeding in the Emergency Department.

Lower gastrointestinal bleeding (LGIB) frequently leads to emergency department (ED) visits and hospitalizations, encompassing a spectrum of outcomes from spontaneous resolution to intrahospital mortality. The purpose of this study was to validate a scoring system designed to identify cases of low-risk LGIB, allowing for safe discharge from the ED. A retrospective analysis of all gastrointestinal bleeding cases presented at three EDs in 2020 was conducted, focusing specifically on patients with LGIB.

Respiratory hospitalizations and ICU admissions among children with and without medical complexity at the end of the COVID-19 pandemic.

Decreased severe respiratory illness was observed during the first 2 years of the COVID-19 pandemic, with a relatively smaller decrease among children with medical complexity (CMC) compared to non-CMC. We extended this analysis to the third pandemic year (April 1, 2022, to March 31, 2023) when pandemic public health measures were loosened. A population-based repeated cross-sectional study evaluated respiratory hospitalizations among CMC and non-CMC (<18 years) in Ontario, Canada.

Discovery of Potent Azetidine-Benzoxazole MerTK Inhibitors with Target Engagement.

Inhibition of the receptor tyrosine kinase MerTK by small molecules has the potential to augment the immune response to tumors. Potent, selective inhibitors with high levels of target engagement are needed to fully evaluate the potential use of MerTK inhibitors as cancer therapeutics. We report the discovery and optimization of a series of pyrazinamide-based type 1.

Discovery of A-910, a Highly Potent and Orally Bioavailable Dual MerTK/Axl-Selective Tyrosine Kinase Inhibitor.

TAM receptor tyrosine kinases have emerged as promising therapeutic targets for cancer treatment due to their roles in both tumor intrinsic survival mechanisms and suppression of antitumor immunity within the tumor microenvironment. Inhibiting MerTK and Axl selectively is believed to hinder cancer cell survival, reverse the protumor myeloid phenotype, and suppress efferocytosis, thereby eliciting an antitumor immune response. In this study, we present the discovery of , a highly potent and selective dual MerTK/Axl inhibitor, achieved through a structure-based medicinal chemistry campaign.

The evidence describing their experiences of inpatient care is distributed across disciplines. The aim of this scoping review was to map the evidence related to the inpatient experience of care for CMC and their families, particularly related to key aspects and methodological approaches, and identify gaps that warrant further study.

Parenteral versus enteral fluids for infants hospitalized with bronchiolitis: The PREFER shared decision-making prospective observational study protocol.

Introduction: Incorporating shared decision-making (SDM) with children and families in hospitals was a top priority identified by patients, caregivers, and clinicians. Bronchiolitis, a common and costly reason for hospitalization in children, is an exemplar condition to study SDM in hospitals. Internationally, clinical practice guidelines differ when recommending intravenous (IV or parenteral) or nasogastric (NG or enteral) fluids for hospitalized infants with bronchiolitis who are unsafe to be fed orally.

Learning to Trust Yourself: Decision-Making Skills Among Parents of Children With Medical Complexity.

Context: Children with medical complexity have substantial medical needs and their caregivers must make many challenging decisions about their care. Caregivers often become more involved in decisions over time, but it is unclear what skills they develop that facilitate this engagement.

Objectives: To describe the skills that caregivers developed as they gained experience making medical decisions.

Experiences of Financial Stress and Supports in Caregivers During Pediatric Hospital Admission.

Background And Objective: In Canada and the United States, ∼1 in 5 children live in poverty, contributing to poor health outcomes. Families with children with chronic illness may experience additional financial stress related to hospitalization. This study aimed to capture experiences of financial needs and supports among caregivers with a child admitted to a tertiary care pediatric hospital to inform hospital-based financial services to reduce financial stress in families.

When rules turn into tools: An activity theory-based perspective on implementation processes and unintended consequences.

The idea that actions of people, organizations or governments may lead to Unintended Consequences (UICs) is not new. In health, UICs have been reported as a result of various interventions including quality improvement initiatives, health information technology implementation, and knowledge translation, especially those involving translation of broad policies (evidence-based medicine and patient-centred care) or system level improvement into actionable items or tools. While some unintended consequences cannot be anticipated, others may be predictable.

Acceptability of the Long-Term In-Home Ventilator Engagement virtual intervention for home mechanical ventilation patients during the COVID-19 pandemic: A qualitative evaluation.

Background: Clinical management of ventilator-assisted individuals (VAIs) was challenged by social distancing rules during the COVID-19 pandemic. In May 2020, the Long-Term In-Home Ventilator Engagement (LIVE) Program was launched in Ontario, Canada to provide intensive digital care case management to VAIs. The purpose of this qualitative study was to explore the acceptability of the LIVE Program hosted via a digital platform during the COVID-19 pandemic from diverse perspectives.

#HowNotToDoPatientEngagement: the engaging with purpose patient engagement framework based on a twitter analysis of community perspectives on patient engagement.

Background: Evaluation of patient engagement practices are frequently researcher-driven, researcher-funded, and asymmetric in power dynamics. Little to no literature on patient experiences in patient engagement exist that is are not framed by institutionally-driven research inquiries (i.e.

Opening the digital front door for individuals using long-term in-home ventilation (LIVE) during a pandemic- implementation, feasibility and acceptability.

Background: The COVID-19 pandemic led to an unprecedented need for virtual healthcare that was safe, acceptable and feasible to deliver. In May 2020, we launched the Long-term In-Home Ventilator Engagement (LIVE) program for ventilator assisted individuals using ventilators hosted on an e-platform in Ontario, Canada.

Objectives: To assess the acceptability, appropriateness, feasibility and usability of the LIVE program reported by patients, family caregivers, and healthcare providers (HCP).

Severe Respiratory Disease Among Children With and Without Medical Complexity During the COVID-19 Pandemic.

Importance: Severe respiratory disease declined during the COVID-19 pandemic, partially due to decreased circulation of respiratory pathogens. However, the outcomes of children with higher risk have not been described using population-based data.

Objective: To compare respiratory-related hospitalizations, intensive care unit (ICU) admissions, and mortality during the pandemic vs prepandemic, among children with medical complexity (CMC) and without medical complexity (non-CMC).

The hepatitis E virus ORF1 hypervariable region confers partial cyclophilin dependency.

Hepatitis E virus (HEV) is an emerging pathogen responsible for more than 20 million cases of acute hepatitis globally per annum. Healthy individuals typically have a self-limiting infection, but mortality rates in some populations such as pregnant women can reach 30 %. A detailed understanding of the virus lifecycle is lacking, mainly due to limitations in experimental systems.

In Vitro Degradation of 3D-Printed Poly(L-lactide-Co-Glycolic Acid) Scaffolds for Tissue Engineering Applications.

The creation of scaffolds for cartilage tissue engineering has faced significant challenges in developing constructs that can provide sufficient biomechanical support and offer suitable degradation characteristics. Ideally, such tissue-engineering techniques necessitate the fabrication of scaffolds that mirror the mechanical characteristics of the articular cartilage while degrading safely without damaging the regenerating tissues. The aim of this study was to create porous, biomechanically comparable 3D-printed scaffolds made from Poly(L-lactide-co-glycolide) 85:15 and to assess their degradation at physiological conditions 37 °C in pH 7.

Thrombin cleavage of the hepatitis E virus polyprotein at multiple conserved locations is required for genome replication.

The genomes of positive-sense RNA viruses encode polyproteins that are essential for mediating viral replication. These viral polyproteins must undergo proteolysis (also termed polyprotein processing) to generate functional protein units. This proteolysis can be performed by virally-encoded proteases as well as host cellular proteases, and is generally believed to be a key step in regulating viral replication.

Patients and Families as Partners in Patient-Oriented Research: How Should They Be Compensated?

Patient and family engagement has become a widely accepted approach in health care research. We recognize that research conducted in partnership with people with relevant lived experience can substantially improve the quality of that research and lead to meaningful outcomes. Despite the benefits of patient-researcher collaboration, research teams sometimes face challenges in answering the questions of how patient and family research partners should be compensated, due to the limited guidance and lack of infrastructure for acknowledging partner contributions.

Incorporating Tantalum Oxide Nanoparticles into Implantable Polymeric Biomedical Devices for Radiological Monitoring.

Longitudinal radiological monitoring of biomedical devices is increasingly important, driven by the risk of device failure following implantation. Polymeric devices are poorly visualized with clinical imaging, hampering efforts to use diagnostic imaging to predict failure and enable intervention. Introducing nanoparticle contrast agents into polymers is a potential method for creating radiopaque materials that can be monitored via computed tomography.

Activity of eftozanermin alfa plus venetoclax in preclinical models and patients with acute myeloid leukemia.

Activation of apoptosis in malignant cells is an established strategy for controlling cancer and is potentially curative. To assess the impact of concurrently inducing the extrinsic and intrinsic apoptosis-signaling pathways in acute myeloid leukemia (AML), we evaluated activity of the TRAIL receptor agonistic fusion protein eftozanermin alfa (eftoza; ABBV-621) in combination with the B-cell lymphoma protein-2 selective inhibitor venetoclax in preclinical models and human patients. Simultaneously stimulating intrinsic and extrinsic apoptosis-signaling pathways with venetoclax and eftoza, respectively, enhanced their activities in AML cell lines and patient-derived ex vivo/in vivo models.
