Hospital Level of Service, Rural-Urban Location, and Neonatal Resuscitation Interventions: A Population Study in Alberta Canada from 2000-2020.

Background And Objectives: Advanced neonatal resuscitation interventions (ANRIs) are rarely performed for late preterm and term infants. However, healthcare providers in community hospitals may need to perform ANRIs, while having limited experience and resources. Understanding practice differences between hospitals of different levels of service (LoS) and rural/urban location may inform quality improvement.

Molybdate uptake interplay with ROS tolerance modulates bacterial pathogenesis.

The rare metal element molybdenum functions as a cofactor in molybdoenzymes that are essential to life in almost all living things. Molybdate can be captured by the periplasmic substrate-binding protein ModA of ModABC transport system in bacteria. We demonstrate that ModA plays crucial roles in growth, multiple metabolic pathways, and ROS tolerance in .

The co-occurrence of multimorbidity and polypharmacy among middle-aged and older adults in Canada: A cross-sectional study using the Canadian Longitudinal Study on Aging (CLSA) and the Canadian Primary Care Sentinel Surveillance Network (CPCSSN).

Background: There is an increasing prevalence of multiple conditions (multimorbidity) and multiple medications (polypharmacy) across many populations. Previous literature has focused on the prevalence and impact of these health states separately, but there is a need to better understand their co-occurrence.

Methods And Findings: This study reported on multimorbidity and polypharmacy among middle-aged and older adults in two national datasets: the Canadian Longitudinal Study on Aging (CLSA) and the Canadian Primary Care Sentinel Surveillance Network (CPCSSN).

Outcomes of mechanical thrombectomy for medium vessel occlusion in acute ischemic stroke patients with ASPECTS 4-5 vs. 6-7: a retrospective, multicenter, and multinational study.

Introduction: Mechanical thrombectomy (MT) efficacy in medium vessel occlusion (MeVO) stroke, particularly in patients with low Alberta Stroke Program Early Computed Tomography Score (ASPECTS), remains less explored.

Methods: This retrospective study analyzed data from 443 AIS patients treated with MT for MeVO and low ASPECTS (4-7) at 37 centers across North America, Asia, and Europe, from September 2017 to July 2021. Patients were categorized into ASPECTS of 4-5 and 6-7.

Lateralizing value of interictal epileptiform discharges and other parameters in hypothalamic hamartoma.

Objective: Hypothalamic hamartomas (HHs) are associated with pharmacoresistant epilepsy. Stereotactic radiofrequency thermocoagulation (SRT) shows promise as a disconnecting intervention. Although magnetic resonance imaging (MRI) is typically used to determine the attachment and intervention side, it presents challenges in cases of bilaterally attached HH, where the epileptogenic side is unclear.

Monkeys Swimming Across Rivers Refine Questions About the Riverine Barrier Hypothesis.

The Riverine Barrier Hypothesis posits that species distributions are limited by large rivers acting as geographical barriers. Accordingly, large rivers have long been thought to be a major driver of the extensive speciation and high levels of biodiversity among platyrrhine primates in South and Central America. Direct observations of river crossings provide evidence that complements studies of genetic diversity that can together shed new light on this hypothesis.

Ultrahigh-Selectivity Photocatalytic Upgrading of Bio-Aldehydes/Diols to Monoalcohols Via In Situ Circumventing Coupling Co-Products Over Janus Single-Atom Pd/TiO.

Photocatalytic transfer hydrogenation of biomass-derived aldehydes to alcohols often results in unwanted coupling co-products. Herein, an ultraselective hydrogen transfer system enabled by in situ oxidative C─C bond cleavage over a Janus single-atom palladium on titanium dioxide (0.5Pd/TiO) photocatalyst is presented.

Direct, non-medical out-of-pocket expenditures for mothers of moderate or late preterm infants in a level II NICU: Comparison of Alberta Family Integrated Care versus standard care.

Objective: To compare direct, non-medical out-of-pocket expenditures (OOPE) between mothers receiving Alberta Family Integrated Care (FICare™) versus standard care (SC) during their infant's neonatal intensive care unit (NICU) admission and explore factors influencing spending extremes.

Methods: In this exploratory, concurrent mixed-methods sub-study, we compared mother-reported OOPE from Alberta FICare™ and SC parent journals. We thematically analyzed hand-written notes from 30 journals with the highest and lowest 5 % of OOPE.

Roles for the long non-coding RNA / in pancreatic beta cell function.

Long non-coding RNAs (lncRNAs) are emerging as crucial regulators of beta cell function. Here, we show that an lncRNA-transcribed antisense to Pax6, annotated as Pax6os1/PAX6-AS1, was upregulated by high glucose concentrations in human as well as murine beta cell lines and islets. Elevated expression was also observed in islets from mice on a high-fat diet and patients with type 2 diabetes.

Cumulative blood pressure load and cognitive decline in older adults: An observational analysis of two large cohorts.

Introduction: Cumulative blood pressure metrics may provide greater precision for measuring temporal risk exposure, especially in later life where data are mixed regarding associations of high blood pressure (BP) on cognitive function. We examined the relationship between greater cumulative exposure to high BP in later life and several domains of cognitive function.

Methods: Individual cognitive assessment scores and BP measurements in older adults (age ≥70 years) at baseline and over approximately 8 years of follow-up were available in the population-based Canadian Victoria Longitudinal Study (VLS) and Swedish Gothenburg H70 Birth Cohort Studies (H70).

Examining the association between public health unit spending and adolescent substance use.

Background: Based on the socio-ecological model of health, socioeconomic policy is an important determinant of population health. Spending decisions by public health units (PHU) have been shown to be associated with population health outcomes. Some studies have found greater PHU spending to be associated with improved population health, while others report mixed findings, warranting further research.

Bayesian modeling framework for optimizing pre-hospital stroke triage decisions.

Ischemic stroke is responsible for significant morbidity and mortality in the United States and worldwide. Stroke treatment optimization requires emergency medical personnel to make rapid triage decisions concerning destination hospitals that may differ in their ability to provide highly time-sensitive pharmaceutical and surgical interventions. These decisions are particularly crucial in rural areas, where transport decisions can have a large impact on treatment times - often involving a trade-off between delay in pharmaceutical therapy or a delay in endovascular thrombectomy.

Pediatric cervical Intravascular Papillary Endothelial hyperplasia (IPEH): A case report of an unusual presentation.

Intravascular Papillary Endothelial hyperplasia (IPEH) are benign vascular lesions rarely described in the pediatric population. We present here the case and the management of a 11-year-old child with a lateral neck mass. The diagnosis of IPEH can be challenging for the clinician and the radiologist as it may mimic other pathologic entities.

Intermediate-dose immune tolerance induction outperforms with faster success, less bleeding, and no added cost in comparison with low dose: a multicenter randomized clinical trial.

Background: Low-dose (LD) or intermediate-dose (MD) immune tolerance induction (ITI) is effective in children with severe hemophilia A (SHA) with high-titer inhibitors (HTIs) and is attractive in countries with economic constraints. However, high-quality evidence of their use is lacking.

Objectives: This was a multicenter randomized clinical trial comparing the efficacy, safety, and medication cost between LD-ITI and MD-ITI for SHA-HTI children.

Neonatal Encephalopathy: Novel Phenotypes and Genotypes Identified by Genome Sequencing.

Background And Objectives: Neonatal encephalopathy (NE) is characterized by an abnormal level of consciousness with or without seizures in the neonatal period. It affects 1-6/1,000 live term newborns. We applied genome sequencing (GS) in term newborns with NE to investigate the underlying genetic causes.

Neuromuscular Ultrasound Training in Neuromuscular Fellowship Programs in Canada: Minding the Gap.

Introduction/aims: Neuromuscular ultrasound (NMUS) is gaining prominence as a valuable tool for diagnosing neuromuscular disorders at the point of care. Neuromuscular disorder diagnostic criteria guidelines have begun incorporating NMUS findings. As interest grows, fellowship programs must consider incorporating training into their curricula.

Integrating the ADS Score with 24-Hour ASPECTS and red cell distribution width for enhanced prediction of stroke-associated pneumonia following intravenous thrombolysis: model development and internal validation.

Introduction: Stroke-associated pneumonia (SAP) is a major cause of mortality during the acute phase of stroke. The ADS score is widely used to predict SAP risk but does not include 24-h non-contrast computed tomography-Alberta Stroke Program Early CT Score (NCCT-ASPECTS) or red cell distribution width (RDW). We aim to evaluate the added prognostic value of incorporating 24-h NCCT-ASPECTS and RDW into the ADS score and to develop a novel prediction model for SAP following thrombolysis.

Notification of blood donors who test positive for transfusion-transmissible infections.

Background And Objectives: Despite screening procedures, a few blood donors confirm positive for transfusion-transmissible infections and are deferred. Effective notification of laboratory results is essential to ensure that donors are advised of confirmed results and to seek medical care. Here we report results from post-notification interviews of Canadian Blood Services donors.

Hummingbirds use compensatory eye movements to stabilize both rotational and translational visual motion.

To maintain stable vision, behaving animals make compensatory eye movements in response to image slip, a reflex known as the optokinetic response (OKR). Although OKR has been studied in several avian species, eye movements during flight are expected to be minimal. This is because vertebrates with laterally placed eyes typically show weak OKR to nasal-to-temporal motion (NT), which simulates typical forward locomotion, compared with temporal-to-nasal motion (TN), which simulates atypical backward locomotion.

Evaluating the prognostic impact of hypoperfusion intensity ratio in acute ischemic stroke patients undergoing early-phase endovascular thrombectomy.

This research aimed to assess the prognostic relevance of the hypoperfusion intensity ratio (HIR) concerning 90-day outcomes in patients with acute ischemic stroke (AIS) managed within the early intervention window. A retrospective review was conducted on AIS patients who received pretreatment computed tomography perfusion imaging and endovascular thrombectomy due to large vessel occlusions in the anterior circulation between January 2020 and September 2022. Clinical data, including the Alberta Stroke Program Early Computed Tomography Score (ASPECTS) from non-contrast CT, along with perfusion metrics such as ischemic core, hypoperfusion extent, core-penumbra mismatch, and HIR, were analyzed.

AI-derived automated quantification of cardiac chambers and myocardium from non-contrast CT: Prediction of major adverse cardiovascular events in asymptomatic subjects.

Our objective was to evaluate the role of artificial intelligence-enabled multi-chamber cardiac volumetry from non-contrast CT for long-term risk stratification in asymptomatic subjects without known coronary artery disease.

Methods: Our study included 2022 asymptomatic individuals (55.

Antiseizure Medications in Poststroke Seizures: A Systematic Review and Network Meta-Analysis.

Background And Objectives: The most effective antiseizure medications (ASMs) for poststroke seizures (PSSs) remain unclear. We aimed to determine outcomes associated with ASMs in people with PSS.

Methods: We systematically searched electronic databases for studies on patients with PSS on ASMs.

Anti-inflammatory effects of moxifloxacin and levofloxacin on cadmium-activated human astrocytes: Inhibition of proinflammatory cytokine release, TLR4/STAT3, and ERK/NF-κB signaling pathway.

Cadmium is a non-essential element and neurotoxin that causes neuroinflammation, which leads to neurodegenerative diseases and brain cancer. To date, there are no specific or effective therapeutic agents to control inflammation and alleviate cadmium-induced progressive destruction of brain cells. Fluoroquinolones (FQs), widely used antimicrobials with effective blood-brain barrier penetration, show promise in being repurposed as anti-inflammatory drugs.
