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.

Introduction: Recent evidence has shown that vitamin C has analgesic and opioid sparing properties in immediate postoperative context. However, this has never been studied for acute musculoskeletal (MSK) emergency department (ED) injuries. The aim of this pilot study is to evaluate the feasibility of conducting a randomized placebo-controlled study to determine the opioid sparing and analgesic effect of vitamin C compared to placebo, in acute MSK injured ED patients.

Article Synopsis
  • The study investigates differences in thrombo-inflammatory responses and outcomes between non-COVID-19 community-acquired pneumonia (CAP) and COVID-19 CAP in hospitalized adults in Canada.
  • Non-COVID-19 CAP patients displayed lower 28-day mortality rates and fewer complications compared to those with COVID-19, indicating a more effective immune response developed over time against bacterial infections.
  • The findings suggest that the complexities of the immune response to COVID-19 resulted in higher mortality rates, highlighting the challenges posed by emerging viruses compared to known pathogens.

Objective: The objective is to externally validate and assess the opportunity to update the Canadian COVID-19 Mortality Score (CCMS) to predict in-hospital mortality among consecutive non-palliative COVID-19 patients infected with Omicron subvariants at a time when vaccinations were widespread.

Design: This observational study validated the CCMS in an external cohort at a time when Omicron variants were dominant. We assessed the potential to update the rule and improve its performance by recalibrating and adding vaccination status in a subset of patients from provinces with access to vaccination data and created the adjusted CCMS (CCMS).

Unlabelled: We aimed to measure the sustainability of health professionals' intention to have serious illness conversations with patients using the Serious Illness Conversation Guide (SICG) after individual-focused training versus team-based training. In a cluster randomised trial, we trained healthcare professionals in 40 primary care clinics and measured their intention to hold serious illness conversations immediately (T1), after 1 year (T2) and after 2 years (T3). Primary care clinics ( = 40) were randomly assigned to individual-focused training (comparator) or team-based training (intervention).

Article Synopsis
  • Symptoms of Post-COVID-19 Condition are often vague, making it hard to identify them compared to other medical issues.
  • In the study, over one-third of emergency department patients with confirmed COVID-19 infections showed symptoms fitting the World Health Organization's criteria for Post-COVID-19 Condition three months later.
  • Notably, one in five patients who tested negative reported similar symptoms, indicating the current clinical criteria's lack of specificity and the need for continued testing during acute infections.

Article Synopsis
  • This study followed 672 emergency department patients with noncardiac chest pain (NCCP) over two years to track changes in pain intensity, frequency, and overall quality of life.
  • Results showed that while many patients improved, 58.1% were NCCP-free after two years, with four distinct pain progression groups identified: worsening, persistent, limited improvement, and remission trajectories.
  • Notably, those in the remission group had better physical and mental quality of life compared to others, highlighting the need for healthcare focus on the persistent symptoms affecting over 40% of the patients.

Background And Objectives: People aged 65 and older, deemed most "vulnerable" by public health, were targeted by the coronavirus disease 2019 protection measures, which sought to minimize physical contact and social activities. Older adults living alone were particularly affected by these measures. However, such measures meant to protect the older population may not have necessarily reflected older adults' individual prioritization choices.

Deep-space missions require preventative care methods based on predictive models for identifying in-space pathologies. Deploying such models requires flexible edge computing, which Open Neural Network Exchange (ONNX) formats enable by optimizing inference directly on wearable edge devices. This work demonstrates an innovative approach to point-of-care machine learning model pipelines by combining this capacity with an advanced self-optimizing training scheme to classify periods of Normal Sinus Rhythm (NSR), Atrial Fibrillation (AFIB), and Atrial Flutter (AFL).

Article Synopsis
  • Critical illness requiring invasive mechanical ventilation can lead to significant physical disability, and early in-bed cycle ergometry may help reduce this impairment when added to standard physiotherapy in ICU patients.
  • A study with 360 adult patients randomly assigned to either early in-bed cycling plus usual physiotherapy or just usual physiotherapy found no significant difference in physical function scores three days after ICU discharge.
  • The addition of cycling did not result in any serious adverse events, indicating it is safe, but did not enhance recovery outcomes compared to standard therapy alone.

The skeletons of long-lived bamboo coral (Family Keratoisididae) are promising archives for deep-water palaeoceanographic reconstructions as they can record environmental variation at sub-decadal resolution in locations where in-situ measurements lack temporal coverage. Yet, detailed three dimensional (3D) characterisations of bamboo coral skeletal architecture are not routinely available and non-destructive investigations into microscale variations in calcification are rare. Here, we provide high-resolution micro-focus computed tomography (µCT) data of skeletal density for two species of bamboo coral (Acanella arbuscula: 5 specimens, voxel size, 15 µm (central branch scans) and 50 µm (complete structure scan); Keratoisis sp.

With increasing interest in RNA as a therapeutic and a potential target, the role of RNA structures has become more important. Even slight changes in nucleobases, such as modifications or protomeric and tautomeric states, can have a large impact on RNA structure and function, while local environments in turn affect protonation and tautomerization. In this work, the application of empirical tools for p and tautomer prediction for RNA modifications was elucidated and compared with ab initio quantum mechanics (QM) methods and expanded toward macromolecular RNA structures, where QM is no longer feasible.
