Understanding brain oxygen metabolism is crucial for evaluating overall health, par-ticularly in high-stress medical situations such as cardiac arrest and cardiopulmonary resuscitation (CPR). This study focuses on two key indicators of metabo-lism: the cerebral metabolic rate (CMRO2) oxidation state redox cytochrome c oxidase (rCCO). Using advanced techniques like hyperspectral near-infrared spectroscopy (hNIRS) laser doppler flowmetry (LDF), we have con-ducted a comprehensive analysis their...
Understanding the pathophysiology of coronavirus disease 2019 (COVID-19) infection remains a significant challenge our times. The gingival crevicular fluid being representative systemic status and having proven track record detecting viruses biomarkers forms logical basis for evaluating presence severe acute respiratory syndrome 2 (SARS-CoV-2). study aimed to assess (GCF) evidence SARS-CoV-2 in 33 patients who were deemed be COVID-19 positive upon nasopharyngeal sampling. An attempt was also...
<h3>Background:</h3> Emergency physicians lack high-quality evidence for many diagnostic and treatment decisions made patients with suspected or confirmed coronavirus disease 2019 (COVID-19). Our objective is to describe the methods used collect ensure data quality of a multicentre registry presenting emergency department COVID-19. <h3>Methods:</h3> This methodology study describes population-based that has been enrolling consecutive COVID-19 since Mar. 1, 2020. Most are collected from...
The Coherent Hemodynamic Spectroscopy (CHS) model provides a quantitative framework for modeling cerebral hemodynamics and metabolism, particularly in response to small physiological perturbations. However, its original approximate formulation it was limited conditions where parameter changes were constrained 10–20%, making unsuitable extreme disruptions such as cardiac arrest. In this study, we present detailed discussion of the algorithm using complete CHS model, which extends by solving...
Evaluating brain oxygen metabolism during cardiac arrest and cardiopulmonary resuscitation (CPR) is essential for improving neurological outcomes guiding clinical interventions in high-stress medical emergencies. This study focused on two key indicators of metabolism: the cerebral metabolic rate (CMRO2) oxidation state redox cytochrome c oxidase (rCCO). Using advanced techniques such as hyperspectral near-infrared spectroscopy (hNIRS) laser Doppler flowmetry (LDF), we conducted a...

Abstract Many health authorities differentiate hospitalizations in patients infected with SARS-CoV-2 as being “for COVID-19” (due to direct manifestations of infection) versus an “incidental” finding someone admitted for unrelated condition. We conducted a retrospective cohort study all hospitalized via 47 Canadian emergency departments, March 2020-July 2022 determine whether infection are less burden and the healthcare system. Using priori standardized definitions applied hospital discharge...
Objectives: Epinephrine is routinely administered to sudden cardiac arrest patients during resuscitation, but the neurologic effects on treated with epinephrine are not well understood. This study aims assess cerebral oxygenation and metabolism ventricular fibrillation arrest, cardiopulmonary administration. Design: To investigate of equal dosages IV administrated following as a continuous infusion or successive boluses we monitored using hyperspectral near-infrared spectroscopy. Settings: A...
Cardiac tissue engineering is an emerging approach for cardiac regeneration utilizing the inherent healing responses elicited by surviving heart using biomaterial templates. In this study, we aimed to develop hydrogel scaffolds following myocardial infarction (MI). Two superabsorbent hydrogels, CAHA2A and CAHA2AP, were developed employing interpenetration chemistry. was constituted with alginate, carboxymethyl cellulose, (hydroxyethyl) methacrylate, acrylic acid, where CAHA2AP prepared...
Importance Early and accurate diagnostic testing for SARS-CoV-2 is essential to initiate appropriate treatment infection control prevention measures among patients presenting the hospital. Objective To evaluate sensitivity of nucleic acid amplification test (NAAT) performed within 24 hours arrival emergency department a nationally representative sample patients. Design, Setting, Participants This study was conducted at 47 hospitals across 7 provinces in Canada participating Canadian COVID-19...
Abstract Background Social isolation and loneliness (SIL) worsens mortality other outcomes among older adults as much smoking. We previously tested the impact of HOW R U? intervention using peer support from similar-aged volunteers demonstrated reduced SIL discharged emergency department (ED). Generativity, defined “the interest in establishing guiding next generation,” can provide an alternative theoretical basis for reducing via intergenerational programs between members younger...
<h3>Background</h3> Although suspicions of cancer may be raised in patients who visit the emergency department, little is known about department use before a diagnosis. We sought to describe among Ontario within 90 days confirmed diagnosis and evaluate factors associated with this use. <h3>Methods</h3> conducted retrospective, population-based study aged 18 years or older had from 2014 2021 using linked administrative databases. The primary outcome was any date. used multivariable logistic...

Outpatient care for patients with heart valve disease (HVD) is best provided by clinics delivered specialists. Modern day practice in the United Kingdom (UK) currently poorly understood and has not been evaluated nearly a decade. Furthermore, COVID 19 pandemic changed management of many chronic diseases, how this impacted unclear.
