Objective: To characterize the burden of RSV disease in Canada by joint analysis of the published literature and hospitalization data from a healthcare administrative database.

Methods: Electronic databases of published literature were searched to identify studies and systematic reviews reporting data on outpatient visits, hospitalizations, intensive care unit (ICU) admissions and deaths associated with RSV infection in adults.

In Situ M2 Bypass for Treatment of Fusiform Middle Cerebral Artery Bifurcation Aneurysm: Technical Case Instruction and Operative Video.

Background And Importance: Fusiform middle cerebral artery (MCA) bifurcation aneurysms can be challenging to treat with standard endovascular or microsurgical techniques. The in situ side-to-side bypass technique represents an elegant revascularization option for these aneurysms when trapping becomes necessary.

Clinical Presentation: A man in his 50s presented for evaluation of an incidentally found fusiform, 10 mm, right MCA bifurcation aneurysm with involvement of both the inferior and superior M2 trunks.

With big data comes big responsibility: Strategies for utilizing aggregated, standardized, de-identified electronic health record data for research.

Electronic health records (EHRs), though they are maintained and utilized for clinical and billing purposes, may provide a wealth of information for research. Currently, sources are available that offer insight into the health histories of well over a quarter of a billion people. Their use, however, is fraught with hazards, including introduction or reinforcement of biases, clarity of disease definitions, protection of patient privacy, definitions of covariates or confounders, accuracy of medication usage compared with prescriptions, the need to introduce other data sources such as vaccination or death records and the ensuing potential for inaccuracy, duplicative records, and understanding and interpreting the outcomes of data queries.

An Integrated Rapid Response Model for Pediatric Patients Requiring In-Patient Medical Stabilization: Lessons Learned to Enable Regional Capacity Building.

There was an unprecedented surge in admissions for medical stabilization of pediatric patients with eating disorders during the COVID-19 pandemic in Ontario. Eleven hospitals established an integrated rapid response model to ensure timely in-patient access for these patients. This population was cared for in re-allocated community hospital beds as a result of engaging hospital leadership, strengthening partnerships, consulting experts, leveraging existing resources and developing regional bed access strategies.

Transition from neonatal to paediatric intensive care of very preterm-born children: a cohort study of children born between 2013 and 2018 in England and Wales.

Background And Objectives: Home dialysis (peritoneal dialysis and home hemodialysis) is an important renal replacement therapy modality option for patients with end-stage kidney disease. As the Internet has become a primary source for healthcare information, this study aimed to analyze the global and regional interests in home dialysis using Google Trends™ data from January 2004 to March 2024.

Design Setting Participants And Measurements: A comprehensive analysis was conducted using Google Trends™ with the search terms "Peritoneal Dialysis" and "Home Hemodialysis.

Cost-effectiveness of high flow nasal cannula therapy versus continuous positive airway pressure for non-invasive respiratory support in paediatric critical care.

Background: High flow nasal cannula therapy (HFNC) and continuous positive airway pressure (CPAP) are two widely used modes of non-invasive respiratory support in paediatric critical care units. The FIRST-ABC randomised controlled trials (RCTs) evaluated the clinical and cost-effectiveness of HFNC compared with CPAP in two distinct critical care populations: acutely ill children ('step-up' RCT) and extubated children ('step-down' RCT). Clinical effectiveness findings (time to liberation from all forms of respiratory support) showed that HFNC was non-inferior to CPAP in the step-up RCT, but failed to meet non-inferiority criteria in the step-down RCT.

Normal-organ distribution of PSMA-targeting PET radiopharmaceutical F-flotufolastat: a post hoc analysis of the LIGHTHOUSE and SPOTLIGHT studies.

Background: High-affinity radiohybrid PSMA-targeting radiopharmaceutical F-flotufolastat (F-rhPSMA-7.3) is newly approved for diagnostic imaging of prostate cancer. Here, we conduct a post hoc analysis of two phase 3 studies to quantify F-flotufolastat uptake in a range of normal organs.

Rapid oxygen titration following cardiopulmonary resuscitation mitigates cerebral overperfusion and striatal mitochondrial dysfunction in asphyxiated newborn lambs.

Asphyxiated neonates must have oxygenation rapidly restored to limit ongoing hypoxic-ischemic injury. However, the effects of transient hyperoxia after return of spontaneous circulation (ROSC) are poorly understood. We randomly allocated acutely asphyxiated, near-term lambs to cardiopulmonary resuscitation in 100% oxygen ("standard oxygen", n = 8) or air (n = 7) until 5 minutes after ROSC, or to resuscitation in 100% oxygen immediately weaned to air upon ROSC ("rapid-wean", n = 7).

Timing of Neonatal Discharge and Unplanned Readmission to PICUs Among Infants Born Preterm.

Importance: Children born very preterm (<32 weeks) are at risk of ongoing morbidity and admission to pediatric intensive care units (PICUs) in childhood. However, the influence of the timing of neonatal discharge on unplanned PICU admission has not been established.

Objective: To examine whether the timing of neonatal discharge (postmenstrual age and season) is associated with subsequent unplanned PICU admission.

Associations of semaglutide with first-time diagnosis of Alzheimer's disease in patients with type 2 diabetes: Target trial emulation using nationwide real-world data in the US.

Introduction: Emerging preclinical evidence suggests that semaglutide, a glucagon-like peptide receptor agonist (GLP-1RA) for type 2 diabetes mellitus (T2DM) and obesity, protects against neurodegeneration and neuroinflammation. However, real-world evidence for its ability to protect against Alzheimer's disease (AD) is lacking.

Methods: We conducted emulation target trials based on a nationwide database of electronic health records (EHRs) of 116 million US patients.

Single-Dose Drug Development Candidate for Schistosomiasis.

Aryl hydantoins were identified in the early 1980s as a promising antischistosomal chemotype. However, as exemplified by Ro 13-3978, this compound series produced antiandrogenic side effects on the host, a not unexpected outcome given their structural similarity to the antiandrogenic drug nilutamide. The two key advances in our optimization of Ro 13-3978 were swapping the aryl trifluoromethyl substituent with a difluoroethyl to abolish antiandrogenic effects and replacing the hydrogen atoms of the -dimethyl substructure with deuterium atoms to increase metabolic stability.
