Obesity reshapes regulatory T cells in the visceral adipose tissue by disrupting cellular cholesterol homeostasis.

Regulatory T cells (T) accumulate in the visceral adipose tissue (VAT) to maintain systemic metabolic homeostasis but decline during obesity. Here, we explored the metabolic pathways controlling the homeostasis, composition, and function of VAT T under normal and high-fat diet feeding conditions. We found that cholesterol metabolism was specifically up-regulated in ST2 VAT T subsets.

Vulnerability: An Interpretive Descriptive Study of Personal Support Workers' Experiences of Working During the COVID-19 Pandemic in Ontario, Canada.

Background/objectives: Personal support workers (PSWs) are important healthcare workers providing essential services to thousands of Canadians. PSWs face many challenges that were exacerbated in the context of the COVID-19 pandemic. In this study we explore experiences of PSWs working through the pandemic in Ontario long-term care (LTC) homes by focusing on the vulnerability of such workers.

Livedoid vasculopathy in hemoglobinopathy-associated chronic leg ulcers.

Chronic leg ulceration is a debilitating manifestation of hemoglobinopathies, and best management is uncertain. Livedoid vasculopathy (LV) is a cutaneous non-inflammatory thrombotic vasculopathy treated with anticoagulation that has been identified in hemoglobinopathy-associated chronic leg ulceration. However, most patients with hemoglobinopathy-associated ulcers do not undergo workup for secondary causes, and the prevalence and relevance of LV is unclear.

PeerOnCall: Exploring how organizational culture shapes implementation of a peer support app for public safety personnel.

Background: Public safety personnel (PSP) such as firefighters, paramedics, and police are exposed to traumatic situations, which increase their risk for mental health issues. However, many PSP do not seek help in a timely manner. Peer support interventions have the potential to decrease stigma and increase treatment-seeking behaviours among PSP.

Eliminating rote postoperative radiographs for surgically managed pediatric supracondylar humerus fractures.

Background: Use of postoperative radiographs after surgical management of supracondylar humerus (SCH) fractures is often based on rote practice rather than evidence. The purpose of this study was to determine the frequency with which 3-week postoperative radiographs at the time of pin removal altered management plans in pediatric SCH fractures that were intraoperatively stable after closed reduction and percutaneous pinning (CRPP).

Methods: We prospectively recruited pediatric patients with SCH fractures managed by CRPP at our institution from June 2020 until June 2022, and reviewed retrospective data on pediatric SCH fractures managed surgically at our institution between April 2008 and March 2015.

Tande nou gwonde! (Hear us roar!)- Youth perspectives of maternal near-misses: Protocol for a photovoice study of young childbearing people's perspectives of maternal near-misses in northwest Haiti.

Introduction: Globally, a shift is occurring to recognize the importance of young peoples' health and well-being, their unique health challenges, and the potential they hold as key drivers of change in their communities. In Haiti, one of the four leading causes of death for those 20-24 years old is pregnancy, childbirth, and the weeks after birth or at the end of a pregnancy. Important gaps remain in existing knowledge about youth perspectives of maternal health and well-being within their communities.

Advancing a collective vision for equity-based cocreation through prototyping at an international forum.

Background: Cocreation has the potential to engage people with lived and living experiences in the design and evaluation of health and social services. However, guidance is needed to better include people from equity-deserving groups (EDGs), who are more likely to face barriers to participation, experience ongoing or historical harm, and benefit from accessible methods of engagement.

Objective: The aim of this international forum (CoPro2022) was to advance a collective vision for equity-based cocreation.

Adopting, implementing and assimilating coproduced health and social care innovations involving structurally vulnerable populations: findings from a longitudinal, multiple case study design in Canada, Scotland and Sweden.

Background: Innovations in coproduction are shaping public service reform in diverse contexts around the world. Although many innovations are local, others have expanded and evolved over time. We know very little, however, about the process of implementation and evolution of coproduction.

Co-creating a new Charter for equitable and inclusive co-creation: insights from an international forum of academic and lived experience experts.

Background: Co-creation approaches, such as co-design and co-production, aspire to power-sharing and collaboration between service providers and service users, recognising the specific insights each group can provide to improve health and other public services. However, an intentional focus on equity-based approaches grounded in lived experience and epistemic justice is required considering entrenched structural inequities between service-users and service-providers in public and institutional spaces where co-creation happens.

Objectives: This paper presents a Charter of tenets and principles to foster a new era of 'Equity-based Co-Creation' (EqCC).

A transfer learning framework to elucidate the clinical relevance of altered proximal tubule cell states in kidney disease.

The application of single-cell technologies in clinical nephrology remains elusive. We generated an atlas of transcriptionally defined cell types and cell states of human kidney disease by integrating single-cell signatures reported in the literature with newly generated signatures obtained from 5 patients with acute kidney injury. We used this information to develop kidney-specific cell-level information ExtractoR (K-CLIER), a transfer learning approach specifically tailored to evaluate the role of cell types/states on bulk RNAseq data.

How I treat the co-occurrence of venous and arterial thromboembolism: anticoagulation, antiplatelet therapy, or both?

Arterial and venous thromboses are classically considered distinct disease states, with arterial thrombosis mediated predominantly by platelets and therefore, treated with antiplatelet therapy, and venous thrombosis mediated by the plasmatic coagulation system and treated with anticoagulation. However, co-occurrence of arterial and venous events is common, and there is increasing evidence of shared risk factors and pathophysiologic overlap. This presents a management challenge: does the patient with venous and arterial thrombosis, require anticoagulation, antiplatelet therapy, or both? Herein, we present a structured approach to the evaluation and management of patients with venous thrombosis who are also at risk for or have a history of an arterial thromboembolic event.

Community level youth-led interventions to improve maternal-neonatal outcomes in low- and middle-income countries: A systematic review of randomised trials.

Background: Evidence on the effectiveness of youth-led interventions for improving maternal-neonatal health and well-being of women and gender diverse childbearing people in low-income and middle-income countries (LMICs) is incomplete. We aimed to summarise the evidence on whether community level youth-led interventions can improve maternal and neonatal outcomes in LMICs.

Methods: We included experimental studies of youth-led interventions versus no intervention, standard care, or another intervention.

Skin Barrier Function: The Interplay of Physical, Chemical, and Immunologic Properties.

An intact barrier function of the skin is important in maintaining skin health. The regulation of the skin barrier depends on a multitude of molecular and immunological signaling pathways. By examining the regulation of a healthy skin barrier, including maintenance of the acid mantle and appropriate levels of ceramides, dermatologists can better formulate solutions to address issues that are related to a disrupted skin barrier.

Accommodating Students with Disabilities: Fieldwork Educators' Experiences.

Fieldwork is an essential part of experiential learning in occupational therapy education. Fieldwork educators identify limits on reasonable accommodation and difficulty implementing disability-related accommodations. Student occupational therapists with disabilities report discrimination from within the profession, including inflexible fieldwork environments.

Advanced practice provider-led clinic for care transitions in newly diagnosed venous thromboembolism: establishment and utilization.

Background: Patients with suspected or newly diagnosed venous thromboembolism (VTE) are often referred to the emergency department (ED) for management, where anticoagulation is initiated. However, when the patient is judged to be suitable for outpatient management, counseling and follow-up specialty care are frequently suboptimal.

Objectives: To establish an advanced practice provider (APP)-led rapid follow-up clinic to improve transitions of care for patients with newly diagnosed deep vein thrombosis or low-risk pulmonary embolism and to provide continued specialty care and support, including management of complications and medication access issues.

A Double-Blind, Randomized, Placebo-Controlled Trial of Ursodeoxycholic Acid (UDCA) in Parkinson's Disease.

Background: Rescue of mitochondrial function is a promising neuroprotective strategy for Parkinson's disease (PD). Ursodeoxycholic acid (UDCA) has shown considerable promise as a mitochondrial rescue agent across a range of preclinical in vitro and in vivo models of PD.

Objectives: To investigate the safety and tolerability of high-dose UDCA in PD and determine midbrain target engagement.
