Studying the Interrelationship between Telecommuting during COVID-19, residential local accessibility, and active travel: a panel study in Montréal, Canada.

The COVID-19 pandemic led to a substantial increase in the number of people working from home (, in turn leading to unprecedented changes in mobility patterns worldwide. Due to the changing context of the pandemic, there is still a significant gap in knowledge regarding the effects of working from home on workers' travel patterns. The main goal of this work is to unravel the interrelationship between telecommuting during the COVID-19 pandemic, the frequency of active travel for non-work utilitarian purposes, and local accessibility levels around workers' homes.

Antimicrobial Activity in Chitosan-Treated Prosthetic Materials: A Systematic Review.

Objective: The antimicrobial effect of prosthetic materials treated with chitosan was systematically reviewed.

Methods: The searches were carried out on PubMed/Medline, Scopus, ISI Web of Science, LILACS, Embase, and Open Grey with searches performed in March 2022. Selection of in vitro studies, data extraction and risk of bias analysis were performed following the PRISMA guidelines and registered at the Open Science Framework.

Nurses' patterns of knowing about HIV disclosure to children.

Objectives: to identify and analyze nurses' patterns of knowing and experiences with the preparation of families for disclosure to children living with HIV seropositivity.

Methods: thirteen pediatric nurses from Rio de Janeiro participated in the research using the sensitive creative method. Data were treated with Orlandi's discourse analysis and Carper's patterns of knowing.

Revisiting the Persisting Tension Between Expert and Lay Views About Brain Death and Death Determination: A Proposal Inspired by Pragmatism.

Brain death or determination of death based on the neurological criterion has been an enduring source of controversy in academic and clinical circles. The controversy chiefly concerns how death is defined, and it also bears on the justification of the proposed criteria for death determination and their interpretation. Part of the controversy on brain death and death determination stems from disputed crucial medical facts, but in this paper I formulate another hypothesis about the nature of ongoing controversies.

3-phase dual-energy CT scan as a feasible salvage imaging modality for the identification of non-localizing parathyroid adenomas: a prospective study.

Objectives: Accurate pre-operative imaging of parathyroid adenomas (PAs) is essential for successful minimally invasive surgery; however, rates of non-localizing PAs can be as high as 18 %. Multiphasic dual-energy CT (DECT) has the potential to increase accuracy of PA detection by enabling creation of paired material maps and spectral tissue characterization. This study prospectively evaluated the utility of 3-phase DECT for PA identification in patients with failed localizatio n via standard imaging.

PolyDOPA Mussel-Inspired Coating as a Means for Hydroxyapatite Entrapment on Polytetrafluoroethylene Surface for Application in Periodontal Diseases.

Inert polytetrafluoroethylene (PTFE) membranes for periodontal regeneration suffer from weak osteoconductive properties. In this work, a strategy for hydroxyapatite (HAp) coating on PTFE films through an adhesive layer of self-polymerized 3,4-dihydroxy-DL-phenylalanine (polyDOPA) was developed to improve surface properties. Physico-chemical and morphological analysis demonstrated the deposition of polyDOPA and HAp, with an increase in surface roughness and wettability.

Maternal dietary antigen avoidance during pregnancy or lactation, or both, for preventing or treating atopic disease in the child.

Background: Some breastfed infants with atopic eczema benefit from elimination of cow milk, egg, or other antigens from their mother's diet. Maternal dietary antigens are also known to cross the placenta.

Objectives: To assess the effects of prescribing an antigen avoidance diet during pregnancy or lactation, or both, on maternal and infant nutrition and on the prevention or treatment of atopic disease in the child.

Using simulation to train junior psychiatry residents to work with agitated patients: a pilot study.

Objective: This article examines the benefit and feasibility of introducing a new, simulation-based learning intervention for junior psychiatry residents.

Method: Junior psychiatry residents were invited to participate in a new simulation-based learning intervention focusing on agitated patients. Questionnaires were used to explore the success of the intervention.

Time-modified confounding.

According to the authors, time-modified confounding occurs when the causal relation between a time-fixed or time-varying confounder and the treatment or outcome changes over time. A key difference between previously described time-varying confounding and the proposed time-modified confounding is that, in the former, the values of the confounding variable change over time while, in the latter, the effects of the confounder change over time. Using marginal structural models, the authors propose an approach to account for time-modified confounding when the relation between the confounder and treatment is modified over time.

The prognostic significance of subsyndromal delirium in elderly medical inpatients.

Objectives: To determine the prognostic significance of subsyndromal delirium (SSD) presentations.

Design: Cohort study.

Setting: University-affiliated primary acute care hospital.

Clips versus suture technique: is there a difference?

Introduction: Coronary artery bypass grafting (CABG) is one of the most common procedures performed today, and wound complications are a major source of morbidity and cost.

Objective: To determine whether there is any difference in wound outcome (including cost in a Canadian context) between a subcuticular suture technique and skin stapling technique for closure of sternal and leg incisions in CABG patients.

Patients And Methods: One hundred and sixty-two patients undergoing CABG were prospectively, randomly placed to have their sternal and leg incisions closed with either a subcuticular suture technique or with a skin clip.
