Canadian Association of Radiologists Cancer Diagnostic Imaging Referral Guideline.

The Canadian Association of Radiologists (CAR) Cancer Expert Panel is made up of physicians from the disciplines of radiology, medical oncology, surgical oncology, radiation oncology, family medicine/general practitioner oncology, a patient advisor, and an epidemiologist/guideline methodologist. The Expert Panel developed a list of 29 clinical/diagnostic scenarios, of which 16 pointed to other CAR guidelines. A rapid scoping review was undertaken to identify systematically produced referral guidelines that provide recommendations for one or more of the remaining 13 scenarios.

Exploration of the Evidence on Discharge From Hospital to Home for Children With Medical Complexity and Their Parents: A Review of the Literature.

Background: Children with medical complexity (CMC) require complex care that parents must independently provide and manage when discharged home from hospital. It is important that parents are adequately prepared to safely transition home from hospital with their child.

Method: A synthesis of findings from research articles was conducted to map and summarize available evidence on CMC and their parents' experiences of discharge from hospital to home.

Self-reports map the landscape of task states derived from brain imaging.

Psychological states influence our happiness and productivity; however, estimates of their impact have historically been assumed to be limited by the accuracy with which introspection can quantify them. Over the last two decades, studies have shown that introspective descriptions of psychological states correlate with objective indicators of cognition, including task performance and metrics of brain function, using techniques like functional magnetic resonance imaging (fMRI). Such evidence suggests it may be possible to quantify the mapping between self-reports of experience and objective representations of those states (e.

Moiré-driven topological electronic crystals in twisted graphene.

In a dilute two-dimensional electron gas, Coulomb interactions can stabilize the formation of a Wigner crystal. Although Wigner crystals are topologically trivial, it has been predicted that electrons in a partially filled band can break continuous translational symmetry and time-reversal symmetry spontaneously, resulting in a type of topological electron crystal known as an anomalous Hall crystal. Here we report signatures of a generalized version of the anomalous Hall crystal in twisted bilayer-trilayer graphene, whose formation is driven by the moiré potential.

Molar Incisor Hypomineralization and Periodontitis in Adolescents: A Population-Based Study.

Aim: To investigate the association between molar incisor hypomineralization (MIH) and periodontitis in adolescents.

Methods: A population-based study was undertaken of Brazilian adolescents aged 18 and 19 years (n = 2515). MIH was assessed according to Ghanim's criteria.

Cohort profile: the BangladEsh Longitudinal Investigation of Emerging Vascular and nonvascular Events (BELIEVE) cohort study.

Purpose: Bangladesh has experienced a rapid epidemiological transition from communicable to non-communicable diseases (NCDs) in recent decades. There is, however, limited evidence about multidimensional determinants of NCDs in this population. The BangladEsh Longitudinal Investigation of Emerging Vascular and nonvascular Events (BELIEVE) study is a household-based prospective cohort study established to investigate biological, behavioural, environmental and broader determinants of NCDs.

Improving sonographic visualisation of the appendix in a regional referral hospital.

Ultrasound is a first-line and often preferred imaging modality in the diagnosis of acute appendicitis. When the appendix is not visualised during a dedicated appendix ultrasound study, patients may require a CT study, which uses ionising radiation, or undergo conservative clinical observation with the inherent risk of clinical deterioration, perforation and sepsis. Median baseline data, at our hospital imaging department, revealed a rate of combined normal and abnormal appendix visualisation of 34.

Toll/interleukin-1 receptor-only genes contribute to immune responses in maize.

Proteins with Toll/interleukin-1 receptor (TIR) domains are widely distributed in both prokaryotes and eukaryotes, serving as essential components of immune signaling. Although monocots lack the major TIR-nucleotide-binding (NB)-leucine-rich repeat (LRR)-type (TNL) immune receptors, they possess a small number of TIR-only proteins, the function of which remains largely unknown. In the monocot maize (Zea mays), there are three conserved TIR-only genes in the reference genome, namely ZmTIR1 to ZmTIR3.

Enhanced analysis of cellulose nanofibril film structure.

Structural analysis of cellulose nanofibril (CNF) films remains challenging due to the stochastic assembly of fibres and presence of nanopores. This limits our ability to link the film structures to their properties, restricting their commercial use. While X-ray micro-computed tomography (μCT) is a powerful technique to map the structure of traditional and commercial paper, there has been limited success in its application for CNF films due to the poor contrast between pores and material, making the reconstructed images difficult to segment and analyse.

Physical exercise for a healthy pregnancy: the role of placentokines and exerkines.

Complications such as diabetes and preeclampsia can occur during pregnancy. Moderate-intensity exercise can prevent such complications by releasing placentokines and exerkines, such as apelin, adiponectin, leptin, irisin, and chemerin. Exercise and apelin increase thermogenesis and glucose uptake in pregnancy by activating AMPK, PI3K, PGC-1α, AKT1, UCP3, and sarcolipin.

Hepatobiliary Adverse Events Associated With the KRAS p.G12C Inhibitor Sotorasib.

Purpose: The p.G12C mutation in KRAS is commonly found in many cancers and was previously untreatable until drugs like sotorasib were developed. However, up to 15% of patients treated with sotorasib have experienced hepatobiliary adverse events.

Differences in Care and Outcomes in Cardiogenic Shock in Cardiac Intensive Care Units in the United States and Canada: CCCTN Registry Insights.

Background: Mortality in cardiogenic shock (CS) remains high. Significant inter-hospital heterogeneity in critical care therapies have been described, which reflects the lack of high-quality evidence to guide optimal treatment. We aimed to describe differences in practices and clinical outcomes among patients with CS in the United States (US) and Canada.

A meta-analysis of intravitreal ranibizumab versus laser photocoagulation for the treatment of retinopathy of prematurity.

Purpose: Laser photocoagulation (LPC) has been a traditional treatment for retinopathy of prematurity (ROP). However, intravitreal anti-VEGF agents such as bevacizumab and ranibizumab (IVR) have also been increasingly used. This meta-analysis aims to rigorously compare IVR to LPC in the treatment of ROP.

Subsidies, Standards, or Both? Trade-Offs among Policies for 100% Zero-Emissions Vehicle Sales.

Numerous regions are committed to reaching 100% light-duty zero-emissions vehicle (ZEV) sales by 2035 or earlier. For the case of Canada, we explore two policy pathways toward this goal: (i) a stringent ZEV sales standard (or mandate) and (ii) a purchase subsidy-based strategy (of three different durations). The AUtomaker-consumer Model (AUM) is used to compare policy impacts on ZEV sales, GHG mitigation, vehicle markups and prices, and automaker profits from 2023 to 2035.

Diagnostic properties of differing BP thresholds for adverse pregnancy outcomes in standard-risk nulliparous women: A secondary analysis of SCOPE cohort data.

Background: In 2017, the American College of Cardiology and American Heart Association (ACC/AHA) lowered blood pressure (BP) thresholds to define hypertension in adults outside pregnancy. If used in pregnancy, these lower thresholds may identify women at increased risk of adverse outcomes, which would be particularly useful to risk-stratify nulliparous women. In this secondary analysis of the SCOPE cohort, we asked whether, among standard-risk nulliparous women, the ACC/AHA BP categories could identify women at increased risk for adverse outcomes.

Prevalence and risk factors of the most common multimorbidity among Canadian adults.

Background: The number of persons living with multimorbidity-defined as the co-occurrence of at least two chronic conditions in the same individual-is growing globally, especially in developed countries. Traditionally, this increase has been attributed to a growing aging population, sedentary lifestyle, obesity, low socioeconomic status, and individual genetic susceptibility.

Objective: To investigate the prevalence and associated risk factors of the most common multimorbidity (MCM) among Canadian middle-aged and older adults.

A dihydrochalcone-specific O-methyltransferase from leaf buds of Populus trichocarpa implicated in bud resin formation.

Production of secreted leaf bud resin is a mechanism for temperate trees to protect dormant leaf buds against frost damage, dehydration, and insect herbivory. Bud resins contain a wide variety of special metabolites including terpenoids, benzenoids, and phenolics. The leaf bud resins of Populus trichocarpa and P.

Tracking Physical Activity and Nutrition Policies and Practices in Early Childhood Education and Care: Five Years Post-Implementation of a Provincial-Level Active Play Standard.

Early childhood education and care (ECEC) settings are key for improving health behaviors, including physical activity (PA) and nutrition. In 2017, the province of British Columbia (BC) implemented a provincial-level Active Play policy supported by a capacity-building intervention. Significant improvements in all PA policies and practices and the majority of nutrition policies were observed post-implementation.

Evaluation of antimicrobial susceptibility testing methods for complex isolates from people with and without cystic fibrosis.

The complex (BCC) is a group of Gram-negative bacteria that cause opportunistic infections, most notably in people with cystic fibrosis (CF), and have been associated with outbreaks caused by contaminated medical products. Antimicrobial susceptibility testing (AST) is often used to guide treatment for BCC infections, perhaps most importantly in people with CF who are being considered for lung transplant. However, recent studies have highlighted problems with AST methods.

Canadian Men's Intimate Partner Relationship Break-Ups During COVID-19: Implications for Mental Health Promotion.

COVID-19 impacted many men's intimate partner relationships, with distressed and disrupted partnerships consistently featured in commentaries with linkages to mental health challenges. The current study draws from interviews with 23 Canadian-based men, 19-50 years old, who experienced a break-up during COVID-19. Addressing the research question, "What are the connections between masculinities, men's mental health, and intimate partner relationship break-ups during COVID-19?", three thematic findings were derived: (1) Virtually Together and Growing Apart, (2) Mentally Trapped, and Failing Fast and Slow, and (3) Introspections and Moving On.

Distribution and role of peripheral arterial chemoreceptors in cardio-respiratory control of the south american rattlesnake (Crotalus durissus).

Peripheral arterial chemoreceptors monitor the levels of arterial blood gases and adjust ventilation and perfusion to meet metabolic demands. These chemoreceptors are present in all vertebrates studied to date but have not been described fully in reptiles other than turtles. The goals of this study were to 1) identify functional chemosensory areas in the South American rattlesnake (Crotalus durissus) 2) determine the neurochemical content of putative chemosensory cells in these areas and 3) determine the role each area plays in ventilatory and cardiovascular control.
