The fission yeast SUMO-targeted ubiquitin ligase Slx8 functionally associates with clustered centromeres and the silent mating-type region at the nuclear periphery.

The SUMO-targeted ubiquitin ligase (STUbL) family is involved in multiple cellular processes via a wide range of mechanisms to maintain genome stability. One of the evolutionarily conserved functions of STUbL is to promote changes in the nuclear positioning of DNA lesions, targeting them to the nuclear periphery. In Schizossacharomyces pombe, the STUbL Slx8 is a regulator of SUMOylated proteins and promotes replication stress tolerance by counteracting the toxicity of SUMO conjugates.

Development and usability testing of a multifaceted intervention to reduce low-value injury care.

Background: Multifaceted interventions that address barriers and facilitators have been shown to be most effective for increasing the adoption of high-value care, but there is a knowledge gap on this type of intervention for the de-implementation of low-value care. Trauma is a high-risk setting for low-value care, such as unnecessary diagnostic imaging and the use of specialized resources. The aim of our study was to develop and assess the usability of a multifaceted intervention to reduce low-value injury care.

The mobile seniors' clinic - an innovative transition of care for frail older adults.

Background: This study aims to evaluate the impact of Quebec's first hospital-at-home-inspired mobile Seniors' Clinic, the "Clinique des Ainés (CDA)", on frail older adults' returns to the Emergency Department (ED), mortality, and hospital Length Of Stay (LOS) and rehospitalizations.

Methods: Design: Quasi-experimental pre-post implementation cohort study.

Population: Patients aged ≥ 75 years admitted to the short-term geriatric unit after an ED consultation (control) or included by the CDA (intervention).

Effective method to mitigate impact of rain or snowmelt sewer flushing events on wastewater-based surveillance measurements.

Wastewater-based surveillance (WBS) is increasingly used for monitoring disease targets in wastewaters around the world. This study, performed in Ottawa, Canada, identifies a decrease in SARS-CoV-2 wastewater measurements during snowmelt-induced sewer flushing events. Observations first revealed a correlation between suppressed viral measurements and periods of increased sewage flowrates, air temperatures above 0 °C during winter months, and solids mass flux increases.

Urban wastewater contains a functional human antibody repertoire of mucosal origin.

Wastewater-based surveillance of human disease offers timely insights to public health, helping to mitigate infectious disease outbreaks and decrease downstream morbidity and mortality. These systems rely on nucleic acid amplification tests for monitoring disease trends, while antibody-based seroprevalence surveys gauge community immunity. However, serological surveys are resource-intensive and subject to potentially long lead times and sampling bias.

Combining Short- and Long-Read Sequencing Technologies to Identify SARS-CoV-2 Variants in Wastewater.

During the COVID-19 pandemic, the monitoring of SARS-CoV-2 RNA in wastewater was used to track the evolution and emergence of variant lineages and gauge infection levels in the community, informing appropriate public health responses without relying solely on clinical testing. As more sublineages were discovered, it increased the difficulty in identifying distinct variants in a mixed population sample, particularly those without a known lineage. Here, we compare the sequencing technology from Illumina and from Oxford Nanopore Technologies, in order to determine their efficacy at detecting variants of differing abundance, using 248 wastewater samples from various Quebec and Ontario cities.

Interprofessional interventions that impact collaboration and quality of care across inpatient trauma care continuum: A scoping review.

Introduction: Despite the recognized importance of interprofessional collaboration (IPC) in trauma care, healthcare professionals often work in silos. Interprofessional (IP) interventions are crucial for optimizing IPC and delivering high-quality care across clinical contexts, yet their effectiveness throughout the inpatient trauma care continuum is not well understood. Thus, this review aimed to examine the literature on the effectiveness of IP interventions on collaboration processes and related outcomes in inpatient trauma care.

Which adults aged 65 and older are at low-risk for cervical spine injuries after low-level falls?

Objectives: The population is aging and falls are a common reason for emergency department visits. Appropriate imaging in this population is important. The objectives of this study were to estimate the prevalence of cervical spine injury and identify factors associated with cervical spine injuries in adults ≥ 65 years after low-level falls.

Nonmedical problems among older adults visiting the emergency department for low acuity conditions: A prospective multicentre cohort study.

Background: Data on the predictors of nonmedical problems (NMP) in older adults attending the emergency department (ED) for low acuity conditions is lacking and could help rapid identification of patients with NMP and integration of these needs into care planning.

Objectives: To determine the prevalence and predictors of NMP among older adults attending EDs for low acuity conditions.

Methods: Prospective cohort study in eight EDs (May-August 2021).

Influence of continuous subcutaneous apomorphine infusion on cognition and behavior in Parkinson's disease: A systematic review.

Introduction: The efficacy of continuous subcutaneous apomorphine infusion (CSAI) for motor complications of Parkinson's disease (PD) is established. However, its effect on cognition and behavior remains controversial. The main objective of this systematic review was to describe the existing literature on the effects of CSAI on cognition and behavior and to determine the quality for each study.

Utility of serial troponin testing for emergency department patients with syncope.

Background: For emergency department (ED) patients with syncope, cardiac troponin can identify acute coronary syndrome (ACS) and prognosticate for 30-day serious adverse events. However, it is unclear if serial testing improves diagnostic yield and prognostication.

Methods: This was a secondary analysis of data from two prospective studies conducted to develop the Canadian Syncope Risk Score.

Wastewater-based surveillance of SARS-CoV-2: Short-term projection (forecasting), smoothing and outlier identification using Bayesian smoothing.

Background: Day-to-day variation in the measurement of SARS-CoV-2 in wastewater can challenge public health interpretation. We assessed a Bayesian smoothing and forecasting method previously used for surveillance and short-term projection of COVID-19 cases, hospitalizations, and deaths.

Methods: SARS-CoV-2 viral measurement from the sewershed in Ottawa, Canada, sampled at the municipal wastewater treatment plant from July 1, 2020, to February 15, 2022, was used to assess and internally validate measurement averaging and prediction.

Resilience after severe critical illness: a prospective, multicentre, observational study (RESIREA).

Background: Critical-illness survivors may experience post-traumatic stress disorder (PTSD) and quality-of-life impairments. Resilience may protect against psychological trauma but has not been adequately studied after critical illness. We assessed resilience and its associations with PTSD and quality of life, and also identified factors associated with greater resilience.

Derivation of the Quebec Brain Injury Categories for complicated mild traumatic brain injuries.

Objective: Approximately 10% of patients with mild traumatic brain injury (TBI) present with intracranial bleeding, and only 3.5% eventually require neurosurgical intervention, which often necessitates interhospital transfer. Better guidelines and recommendations are needed to manage complicated mild TBI in the emergency department (ED).

Identification and Management of Pelvic Fractures in Prehospital and Emergency Department Settings.

Introduction: This study aims to describe the characteristics of patients with a pelvic fracture treated at a level 1 trauma center, the proportion of prehospital undertriage and the use of pelvic circumferential compression device (PCCD).

Methods: This is a retrospective cohort study. Prehospital and inhospital medical records of adults (≥16 y old) with a pelvic fracture who were treated at Hopital de l'Enfant-Jesus-CHU de Québec (Quebec City, Canada), a university-affiliated level 1 trauma center, between September 01, 2017 and September 01, 2021 were reviewed.

An Emergency Medical Technician Administered Falls-Assessment Protocol to Safely Identify Elderly Adults with Non-Urgent Conditions that may Avoid Transport to Emergency Department.

Background: Approximately two-thirds of patients transported to emergency departments (ED) for a fall are discharged from the ED without urgent treatment. This pilot study tests the feasibility of implementing a pre-hospital falls-assessment protocol performed by emergency medical technicians (EMTs) to determine whether a patient who fell needs an ED assessment or could be referred safely to a community resource.

Methods: The protocol was administered by trained EMTs to adults aged ≥ 65 after a fall between October 2019 and March 2020 in Sherbrooke (QC).

Prolonged Physiotherapy after Anterior Cruciate Ligament Reconstruction Does Not Improve Muscular Strength and Function.

After the rupture of the anterior cruciate ligament (ACL), surgery is proposed in the case of knee instability or for athletes who want to return to a pivotal and/or contact sport. The current trend is to extend physiotherapy sessions until a patient's return to sport. We aimed to assess the interest in prolonging the physiotherapy sessions up to 4 postoperative months to restore muscle knee strength and function.
