A national cross-sectional survey of health literacy of caregivers attending Canadian pediatric emergency departments.

Background: Health literacy assessment is key to better meeting family needs and developing informed strategies to promote positive health outcomes for children. The objective of this study was to describe the health literacy of caregivers who use Canadian pediatric emergency departments and relate it to demographic and visit-specific variables.

Methods: This study utilized a descriptive, cross-sectional survey design with medical record review.

Structural insights into the enzymatic breakdown of azomycin-derived antibiotics by 2-nitroimdazole hydrolase (NnhA).

The antibiotic 2-nitroimidazole (2NI) or azomycin, used for treating drug-resistant tuberculosis and imaging tumor hypoxia, requires activation by bacterial nitroreductases for its antibiotic and cytotoxic effect. Mycobacterium sp. JS330 produces 2-nitroimidazole nitrohydrolase (NnhA) that circumvents 2NI activation, conferring 2NI resistance by hydrolysing it to nitrite and imidazol-2-one (IM2O) instead.

A research protocol to study the critical time window for rehabilitation after incomplete spinal cord injury: early vs. late locomotor training.

Spinal cord injury (SCI) often results in severe motor and sensory deficits, leading to significant disability. Preclinical studies and retrospective studies suggest that a critical window of enhanced neuroplasticity may exist immediately after SCI, during which therapeutic interventions could yield greater functional improvements. The impact of time interval since SCI on efficacy of rehabilitation has not been directly assessed and is the focus of this clinical trial.

Multiconfigurational Electronic Structure of Nickel Cross-Coupling Catalysts Revealed by X-ray Absorption Spectroscopy.

Ni 2,2'-bipyridine complexes are commonly invoked intermediates in metallaphotoredox cross-coupling reactions. Despite their ubiquity, design principles targeting improved catalytic performance remain underdetermined. A series of Ni(bpy)(Ar)Cl (R = MeOOC, -Bu, R' = CH, CF) complexes were proposed to have multiconfigurational electronic structures on the basis of multiconfigurational/multireference calculations, with significant mixing of Ni → bpy metal-to-ligand charge transfer (MLCT) configurations into the ground-state wave function.

Circulating cytokine associations with clinical outcomes in melanoma patients treated with combination nivolumab plus ipilimumab.

Nivolumab plus ipilimumab (aCTLA-4/aPD-1) combination therapy has significantly improved clinical outcomes in patients with metastatic melanoma, with 50%-60% of patients responding to treatment, but predictors of response are poorly characterized. We hypothesized that circulating cytokines and peripheral white blood cells may predict response to therapy and evaluated 15 cytokines and complete blood counts (CBC with differentials) from 89 patients with advanced melanoma treated with combination therapy from three points in time: pre-treatment, one month and approximately three months after starting therapy. Clinical endpoints evaluated included durable clinical benefit (DCB), progression-free survival (PFS), and overall survival (OS).

Impact of Intracellular Proteins on μ-Opioid Receptor Structure and Ligand Binding.

Chronic pain is a prevalent problem affecting approximately one out of every five adults in the U.S. The most effective way to treat chronic pain is with opioids, but they cause dangerous side effects such as tolerance, addiction, and respiratory depression, which makes them quite deadly.

Does Chronic Kidney Disease Influence Revascularization Strategy After Acute Coronary Syndrome? A Systematic Review and Meta-Analysis.

Background: Coronary artery bypass grafting (CABG) provides superior long-term outcomes to percutaneous coronary intervention (PCI) for complex multivessel coronary artery disease (CAD). People with chronic kidney disease (CKD) have increased prevalence of multivessel CAD, but also increased surgical risk. We investigated whether CKD predicted real-world use of CABG, versus PCI, in patients revascularized for acute coronary syndrome (ACS).

A prognostic model for predicting functional impairment in youth mental health services.

Background: Functional impairment is a major concern among those presenting to youth mental health services and can have a profound impact on long-term outcomes. Early recognition and prevention for those at risk of functional impairment is essential to guide effective youth mental health care. Yet, identifying those at risk is challenging and impacts the appropriate allocation of indicated prevention and early intervention strategies.

Engaging Red River Métis families in Manitoba in the development of child health resources - findings from a qualitative study.

Background: Most research that includes Red River Métis tends to be pan-Indigenous. Grouping Métis with First Nations and Inuit can diminish their unique and diverse experiences, as well as distinctions-based approaches. Taking a step toward addressing this problem, the Manitoba Métis Federation (MMF; the national government of the Red River Métis) invited researchers within the Canadian network Translating Emergency Knowledge for Kids to partner in this research, which focuses on understanding engagement strategies that can help expose Red River Métis parents to child health research opportunities and build trust and transparency amongst research partners and participants.

The limited clinical utility of a routine creatine kinase (CK) on admission to a psychiatric inpatient unit.

Background: Creatine kinase (CK) is an intracellular enzyme expressed most commonly in tissues such as skeletal muscle. CK can be used as an investigation to support the diagnosis of conditions such as neuroleptic malignant syndrome (NMS), a rare idiosyncratic drug reaction - classically to antipsychotic medications - which can be fatal. Routine screening of CK in psychiatric inpatients is a known practice, but its value is uncertain.

Dietitians as innovators: a deductive-inductive qualitative analysis.

Background: Frontline health professionals are well-placed to develop and implement beneficial innovations. Evidence supports the clinical and financial benefits of Registered Dietitian (RD)-led improvement initiatives, but we know little about how RDs perceive of innovation or of themselves as innovators. The objectives of the study were to gain an understanding of: 1) how RDs define innovation; 2) who RDs perceive as innovative; 3) whether RDs feel prepared to innovate, and; 4) to what extent work context impacts RDs' capacity to innovate at work.

Methodological report of a cross-sectional survey of abortion-related knowledge, attitudes and practices amongst health professionals in Britain, strategies adopted and lessons learned: evidence from the SACHA Study.

Background: Most surveys examining health professionals' knowledge, attitudes and practices around abortion have used convenience samples and have targeted doctors. Our goal in the SACHA Study, drawing on evidence-based strategies to maximise response rates, was to achieve a representative sample of a wider range of health professionals, working in general practice, maternity services, pharmacies, sexual and reproductive health (SRH) clinics and specialist abortion services in Britain, to explore the knowledge, attitudes and experience of abortion care and views on future models of delivery.

Methods: A cross-sectional questionnaire-based survey of midwives, doctors, nurses and pharmacists in England, Scotland and Wales was undertaken between November, 2021 and July, 2022.

Women's perspectives of molecular breast imaging: a qualitative study.

Background: Mammography has poor sensitivity in dense breast tissue. Retrospective studies suggest that Molecular Breast Imaging (MBI), has superior diagnostic accuracy to mammography in women with very dense breast tissue. Women's perspectives of MBI are unknown, but are crucial to understanding the feasibility of, and routes to, adoption into practice.

Association Between Delayed/Forgone Medical Care and Resource Utilization Among Women with Breast Cancer in the United States.

Background: Although high treatment costs of breast cancer care are well documented, the relationship between delayed/forgone (D/F) care and resource utilization among patients with breast cancer is unknown. This study sought to investigate the relationship between D/F care, resource use, and healthcare expenditures among patients with breast cancer.

Methods: Data on adult female patients with breast cancer were obtained from the Medical Expenditure Panel Survey to assess resource utilization and expenditures in the United States from 2007 to 2017.

Elective outpatient middle meningeal artery embolization for chronic subdural hematoma is safe.

Background: Middle meningeal artery embolization (MMAE) is a safe and effective treatment for chronic subdural hematoma (cSDH); however, the appropriate level of postoperative care is unknown.

Objective: To evaluate whether elective MMAE for cSDH could be safely performed in an outpatient setting.

Methods: This was a multicenter, retrospective study of patients with cSDH who underwent elective MMAE.

Supporting equitable cervical cancer elimination for Australia's culturally and linguistically diverse communities: A call for intersectoral action.

Cervical cancer is a preventable disease and is related to persistent health equities. Whilst several priority populations face health inequities related to cervical cancer prevention, my co-authors and I bring special attention to those who identify as culturally and linguistically diverse (CALD). By reflecting on some of our research and work experiences, we propose four ways that governments and policymakers can enact the community engagement goals of the published and proposed cervical cancer prevention and treatment strategies for CALD communities.

Five Year Outcomes in Low-Risk Patients Undergoing Surgery in the PARTNER 3 Trial.

Background: Surgery remains an important treatment for low-risk patients with severe symptomatic aortic stenosis (AS). We evaluated 5-year outcomes in low-risk patients undergoing isolated surgical aortic valve replacement (SAVR) or SAVR with concomitant procedures within the randomized PARTNER 3 trial.

Methods: In the PARTNER 3 trial, 454 patients underwent surgery for severe, symptomatic, tri-leaflet AS and were followed for 5 years.

Ancient genomes reveal a deep history of treponemal disease in the Americas.

Human treponemal infections are caused by a family of closely related Treponema pallidum that give rise to the diseases yaws, bejel, pinta and, most famously, syphilis. Debates on both a common origin for these pathogens and the history of syphilis itself has weighed evidence for the "Columbian hypothesis", which argues for an American origin, against that for the "pre-Columbian hypothesis", which argues for presence of the disease in Eurasia in the Medieval period and possibly earlier. While molecular data has provided a genetic basis for distinction of the typed subspecies, deep evolution of the complex has remained unresolved due to limitations in the conclusions that can be drawn from the sparse paleogenomic data currently available.

Consumption of antimicrobials for use in food-producing animals in New Zealand, a measure of progress in reduction from 2015 to 2022.

Aims: To describe progress in the reduction of the consumption of antimicrobial drugs by food-producing animals in New Zealand to 2022 and to identify the animal production sectors where progress has been greatest, and those where opportunities remain.

Methods: Data were sourced from official government and industry reports to update previous estimates of consumption (as sales) of antimicrobial products applied to food-producing animals in New Zealand, European countries and the USA. Antimicrobial consumption (AMC) was estimated based on the amount of active ingredient sold, per kg of animal biomass standardised to the probable weight at time of treatment or lifetime mean weight but not slaughter weight (population correction unit; PCU).

Prevalence of Diabetic Retinopathy and Dilated Fundus Examinations by Metropolitan Status from 2017-2021: An Assessment of the Behavioral Risk Factor Surveillance System.

Purpose: Diabetic eye disease, namely diabetic retinopathy (DR), remains a leading cause of preventable blindness worldwide. Research has shown that treatment for diabetes and eye care was disrupted during the pandemic - with disparities between urban and rural populations being unknown. Thus, we aimed to assess the prevalence of reported rates of DR and dilated fundus exams from 2017 to 2021.
