Comparison of the analgesic dose of intravenous ketamine versus ketorolac in patients with chest trauma: A randomized double-blind clinical trial.

Background: Pain management is a critical part of treatment in patients with chest trauma. Opioids and nonsteroidal anti-inflammatory drugs have been the most commonly used medications. However, their side effects have drawn attention to other medications.

Central Taxa Are Keystone Microbes During Early Succession.

Microorganisms underpin numerous ecosystem processes and support biodiversity globally. Yet, we understand surprisingly little about what structures environmental microbiomes, including how to efficiently identify key players. Microbiome network theory predicts that highly connected hubs act as keystones, but this has never been empirically tested in nature.

Humidity-Sensing and Moisture-Steering Liquid Crystal Elastomer Actuator.

A liquid crystal elastomer (LCE) actuator capable of colorimetric humidity sensing is realized. The designed LCE features acid protonated amino azobenzene side groups in its structure, which endow the actuator with the hygroscopicity and act as the humidity reporter via color changes. Given that the protonated and deprotonated chromophore absorb visible light at different wavelengths, when the protonated LCE is under higher humidity, it absorbs more water that deprotonates azobenzene and leads to a change in color.

Assessing metal-induced glycation in French fries.

Non-enzymatic glycation is the chemical reaction between the amine group of an amino acid and the carbonyl group of a reducing sugar. The final products of this reaction, advanced glycation end-products (AGEs), are known to play a key role in aging and many chronic diseases. The kinetics of the AGE formation reaction depends on several factors, including pH, temperature, and the presence of prooxidant metals, such as iron and copper.

Professionals' Perspectives of Smart Stationary Bikes in Rehabilitation: Qualitative Study.

Background: Stationary bikes are used in numerous rehabilitation settings, with most offering limited functionalities and types of training. Smart technologies, such as artificial intelligence and robotics, bring new possibilities to achieve rehabilitation goals. However, it is important that these technologies meet the needs of users in order to improve their adoption in current practice.

Habitat Restorations in an Urban Landscape Rapidly Assemble Diverse Pollinator Communities That Persist.

Ecological restoration is a leading approach to mitigating biodiversity decline. While restoration often leads to an immediate increase in species abundance or diversity, it is rarely clear whether it supports longer-term biodiversity gains at the landscape scale. To examine the impacts of urban restoration on pollinator biodiversity, we conducted a 3-year natural experiment in 18 parks across a large metropolitan area.

Environmental Conditions Modulate Warming Effects on Plant Litter Decomposition Globally.

Empirical studies worldwide show that warming has variable effects on plant litter decomposition, leaving the overall impact of climate change on decomposition uncertain. We conducted a meta-analysis of 109 experimental warming studies across seven continents, using natural and standardised plant material, to assess the overarching effect of warming on litter decomposition and identify potential moderating factors. We determined that at least 5.

Clinical presentations and complications of lichen sclerosus: A systematic review.

Lichen sclerosus (LS) is a chronic, inflammatory dermatosis most commonly characterized by changes in skin pigmentation and pruritus, with associated dyspareunia and genital architectural changes. There are a variety of complications associated with LS, which further worsen a patient's health-related quality of life. A systematic review was conducted to summarize the literature regarding clinical features of LS, as well as LS-associated complications.

Facile Preparation of Carbon Nanotube-Based Skin-Like Pressure Sensors.

Flexible sensors have garnered significant interest for their potential to monitor human activities and provide valuable feedback for healthcare purposes. Single-walled carbon nanotubes (SWNTs) are promising materials for these applications but suffer from issues of poor purity and solubility. Dispersing SWNTs with conjugated polymers (CPs) enhances solution processability, yet the polymer sidechains can insulate the SWNTs, limiting the sensor's operating voltage.

A Socioecological Approach to Support the Transition to Adult Care for Youth With Medical Complexity: Family Perspectives and Recommendations.

Introduction: The transition from paediatric to adult health care (i.e., 'health care transition') poses many challenges for youth with medical complexity (YMC) and their families.

Nurses' Perceptions of Practice Supports Related to Medical Assistance in Dying.

Since the inception of medical assistance in dying (MAiD) in Canada in 2016, the health care system continues to refine MAiD delivery models. The frameworks informing nursing practice related to MAiD are subject to variability across the country, leading to nursing role ambiguity and barriers in relational practice. Using critical incident technique, this qualitative research study explores the experiences of 7 Canadian nurses engaging with patients seeking MAiD.

Transfection Potency of Lipid Nanoparticles Containing mRNA Depends on Relative Loading Levels.

When formulating mRNA into lipid nanoparticles (LNP), various copy numbers of mRNA are encapsulated, leading to a distribution of mRNA loading levels within the LNPs. It is unclear whether the mRNA loading level affects the functional delivery of the message. Here we show that depending on the mRNA loading level, LNPs exhibit distinct mass densities and can be fractionated via ultracentrifugation.

R3Design: deep tertiary structure-based RNA sequence design and beyond.

The rational design of Ribonucleic acid (RNA) molecules is crucial for advancing therapeutic applications, synthetic biology, and understanding the fundamental principles of life. Traditional RNA design methods have predominantly focused on secondary structure-based sequence design, often neglecting the intricate and essential tertiary interactions. We introduce R3Design, a tertiary structure-based RNA sequence design method that shifts the paradigm to prioritize tertiary structure in the RNA sequence design.

Tea Polyphenol-Derived Carbon Dots Alleviate Abdominal Aortic Aneurysm Progression by Mitigating Oxidative Stress and Ferroptosis.

Abdominal aortic aneurysm (AAA) is a cardiovascular disease with potentially fatal consequences, yet effective therapies to prevent its progression remain unavailable. Oxidative stress is associated with AAA development. Carbon dots have reactive oxygen species-scavenging activity, while green tea extract exhibits robust antioxidant properties.

Outcomes Using a Standardized Provincial Childhood Nephrotic Syndrome Clinical Pathway.

Background: In 2013, the British Columbia (BC) Childhood Nephrotic Syndrome Clinical Pathway (CNSCP) was developed to standardize the care of children with nephrotic syndrome (NS). In BC, children access nephrology care at BC Children's Hospital (BCCH) and multiple regional clinics.

Objective: The primary objective was to compare induction therapy and clinical outcomes between BCCH and regional clinics since implementation of the CNSCP.

Case Series of Infection-Related Glomerulonephritis in Quebec Indigenous Peoples.

Rationale: Infection-related glomerulonephritis (IRGN) is an immune-mediated glomerulonephritis caused by extra-renal infectious diseases. There has been an important shift in epidemiology in recent years, with a significant proportion of adults affected. The incidence of IRGN is higher amongst Indigenous populations and especially in those with multiple comorbidities.

Enhancing meniscal repair with tough adhesive puncture sealing (TAPS) suture: A proof-of-concept study on bovine cadaveric knees.

Purpose: The objective was to use cyclic tensile loading to compare the gap formation at suture site of three different suture materials to repair bovine radial meniscal tears: (1) polyglactin sutures, (2) tough adhesive puncture sealing (TAPS) sutures and (3) ultra-high molecular weight polyethylene (UHMWPE) sutures.

Methods: Twelve ex vivo bovine knees were dissected to retrieve the menisci. Complete radial tears were performed on 24 menisci, which were then separated into three groups and repaired using either pristine 2-0 polyglactin sutures, TAPS sutures (2-0 polyglactin sutures coated with adhesive chitosan/alginate hydrogels) or 2-0 UHMWPE sutures with a single stitch.

Durvalumab and tremelimumab in patients with advanced rare cancer: a multi-centre, non-blinded, open-label phase II basket trial.

Background: Dual inhibition of cytotoxic T-lymphocyte associated protein 4 (CTLA-4) and programmed death ligand 1 (PD-L1) has been shown to be an effective treatment strategy in many cancers. We sought to determine the objective response rate of combination durvalumab (D) plus tremelimumab (TM) in parallel cohorts of patients with carefully selected rare cancer types in which these agents had not previously been evaluated in phase II trials and for which there was clinical or biological rationale for dual immune checkpoint inhibitor therapy to be active.

Methods: We designed a multi-centre, non-blinded, open-label phase II basket trial with each of the following 8 rare cancers considered a separate phase II trial: salivary carcinoma, carcinoma of unknown primary (CUP) with tumour infiltrating lymphocytes and/or expressing PD-L1, mucosal melanoma, acral melanoma, osteosarcoma, undifferentiated pleomorphic sarcoma, clear cell carcinoma of the ovary (CCCO) or squamous cell carcinoma of the anal canal (SCCA).

Global, regional, and national burdens of heart failure in adolescents and young adults aged 10-24 years from 1990 to 2021: an analysis of data from the Global Burden of Disease Study 2021.

Background: Prior studies suggest prevalence of heart failure (HF) has remained steady or progressively decreased over past 30 years in the general population. Whether this favourable trend occurred in adolescents and young adults aged 10-24 years has yet to be elucidated. We aim to identify the trends in the burden of HF in this young population from 1990 to 2021 to inform areas for targeted intervention and prevention efforts.

Analysis of the International Index of Erectile Function: psychometric evidence and measurement invariance across relationship status and age generations in a Chilean sample.

Background: The International Index of Erectile Function (IIEF) stands out for its utility and widespread use to measure sexual function in men. However, it lacks consistency in its internal latent structure across studies, has not been evaluated for measurement invariance, and has not undergone psychometric validation for its 15-item form in Spanish among South American countries.

Aim: To examine the IIEF's psychometric evidence (ie, structural/criterion validity and reliability) in a sample of adult men and determine its measurement invariance across relationship status (single vs in a relationship) and age generations (generations Z, Y/millennials, and X).

Association between number of medications and indicators of potentially inappropriate polypharmacy: a population-based cohort of older adults in Quebec, Canada.

Background: As the number of medications increases, the appropriateness of polypharmacy may become questionable due to the heightened risk of medication-related harm.

Objectives: (1) To investigate the relationship between the number of current medications used by older adults and three indicators of potentially inappropriate polypharmacy: (a) the mean number of potentially inappropriate medications (PIMs), (b) the average count of drug-drug interactions, and (c) the anticholinergic burden; (2) To characterize the population-based burden of potentially inappropriate polypharmacy by calculating the proportion of individuals with these indicators.

Design: We conducted a population-based observational study using the Quebec Integrated Chronic Disease Surveillance System.

Ocular and perineal squamous cell carcinomas in a Holstein Friesian cow.

Background: Squamous cell carcinoma (SCC) in domestic cattle is an economically significant malignant neoplasm and has been documented primarily in ocular and periocular tissues, vulva, and perineum. SCCs are often slow-growing and locally invasive, but metastasis is uncommon. Increased risk of developing SCC has been predominantly associated with high levels of sunlight exposure and hypopigmentation (skin and conjunctiva).

Case report: Canadian consensus on chlormethine gel use in mycosis fungoides-CTCL: literature review and real-world experience.
