Physician databases constitute an essential component of health workforce planning. However, while some countries have established functioning national physician databases, others have failed to do so. We compared the healthcare systems of two technologically and economically developed countries, Canada and Israel, which represent cases of respective success and failure in establishing physician databases.

Prions are assemblies of misfolded prion protein that cause several fatal and transmissible neurodegenerative diseases, with the most common phenotype in humans being sporadic Creutzfeldt-Jakob disease (sCJD). Aside from variation of the prion protein itself, molecular risk factors are not well understood. Prion and prion-like mechanisms are thought to underpin common neurodegenerative disorders meaning that the elucidation of mechanisms could have broad relevance.

High resolution infrared spectra of water-CO dimers are further studied using tunable infrared sources to probe a pulsed slit jet supersonic expansion. The relatively weak transition of DO-CO in the DO ν fundamental region (≈2760 cm) is observed for the first time, as are various spectra of DO-CO. Combination bands involving the intermolecular in plane geared bend (disrotatory) mode are observed for HO-CO (≈1642, 2397 cm) in the HO ν and CO ν regions, for HDO-CO (≈2761 cm) in the HDO ν region, and for DO-CO (≈2386, 2705 and 2821 cm) in the CO ν, DO ν, and DO ν regions.

Fungi are well known for their ability to both produce and catabolize complex carbohydrates to acquire carbon, often in the most extreme of environments. Glucuronoxylomannan (GXM)-based gel matrices are widely produced by fungi in nature and though they are of key interest in medicine and pharmaceuticals, their biodegradation is poorly understood. Though some organisms, including other fungi, are adapted to life in and on GXM-like matrices in nature, they are almost entirely unstudied, and it is unknown if they are involved in matrix degradation.

The high social value placed on motherhood often means that childless women experience family and social stigmatization. Faced with this situation, some childless women join Internet discussion groups to share their experiences. Based on the testimonies of Quebec women who were involuntarily infertile, this article examines how online discussion groups enabled childless women to come together, support each other, denounce the forms of devaluation they suffered in the social and intimate spheres, and claim their specific role and place in their family and society.

Aim: Accurate and appropriate cognitive screening can significantly enhance early psychosis care, yet no screening tools have been validated for the early psychosis population and little is known about current screening practices, experiences, or factors that may influence implementation. CogScreen is a hybrid type 1 study aiming to validate two promising screening tools with young people with first episode psychosis (primary aim) and to understand the context for implementing cognitive screening in early psychosis settings (secondary aim). This protocol outlines the implementation study, which aims to explore the current practices, acceptability, feasibility and determinants of cognitive screening in early psychosis settings from the perspective of key stakeholders.

Background: Many people with kidney failure start and remain on in-centre haemodialysis treatment despite evidence of improved outcomes with home dialysis. To make an informed modality decision patients must receive frequent, high-quality modality education. This education is inconsistent in the in-centre haemodialysis setting, where patients spend the most time with nurses while receiving haemodialysis treatments.

Polymyxins are last-resort antimicrobial peptides administered clinically against multi-drug resistant bacteria, specifically in the case of Gram-negative species. However, an increasing number of these pathogens employ a defense strategy that involves a relay of enzymes encoded by the pmrE (ugd) loci and the arnBCDTEF operon. The pathway modifies the lipid-A component of the outer membrane (OM) lipopolysaccharide (LPS) by adding a 4-amino-4-deoxy-l-arabinose (L-Ara4N) headgroup, which renders polymyxins ineffective.

Background: The treatment of glioblastomas (GBM) with radiation therapy is extremely challenging due to their invasive nature and high recurrence rate within normal brain tissue.
Purpose: In this work, we present a new metric called the tumour spread (TS) map, which utilizes diffusion tensor imaging (DTI) to predict the probable direction of tumour cells spread along fiber tracts. We hypothesized that the TS map could serve as a predictive tool for identifying patterns of likely recurrence in patients with GBM and, therefore, be used to modify the delivery of radiation treatment to pre-emptively target regions at high risk of tumour spread.

Background: Since national essential medicine lists guide the procurement of medicines for populations in many countries, and cardiovascular diseases are the leading cause of death globally, including cardiovascular medicines on these lists can significantly impact healthcare outcomes.
Methods: In this cross-sectional study, national essential medicines' lists from 158 countries were analysed on whether or not they included medicines to treat ischemic heart disease, cerebrovascular disease, and hypertensive heart disease. A linear regression model was used to evaluate the association between countries' coverage scores and amenable mortality.

Symptomatic carotid disease, characterized by atherosclerotic or non-atherosclerotic internal carotid artery disease with ipsilateral stroke symptoms, represents a critical condition in stroke neurology. This "hot carotid" state carries a high risk of stroke recurrence, with almost one-fourth of the patients experiencing recurrent ischemic events within 2 weeks of initial presentation. The global prevalence of significant carotid stenosis (conventionally defined as ≥50% narrowing) is estimated at around 1.

This study investigated the relationship between the frailty index and all-cause and cause-specific mortality in patients with depression. We recruited 2,669 participants with depression from the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2018 and quantified their frailty status using a 53-item frailty index. Cox proportional hazards models were used to estimate hazard ratios (HR) and their 95% confidence intervals (CI).

Purpose: Pediatric health outcomes are often assessed using proxy reports, which may not fully capture children's experiences. Children with surgical conditions face unique, changing healthcare journeys, making accurate representation challenging. This review compares child-reported health status and treatment experiences from Patient-Reported Outcome Measures (PROMs) and Patient-Reported Experience Measures (PREMs) with parent reports.

Introduction: Group B Streptococcus (GBS) is an opportunistic pathogen that can induce chorioamnionitis (CA), increasing the risk of neurodevelopmental disorders (NDDs) in the offspring. The placenta facilitates maternal-fetal communication through the release of extracellular vesicles (EVs), which may carry inflammatory molecules such as interleukin (IL)-1. Although the role of EVs in immune modulation is well established, their specific characterization in the context of GBS-induced CA has not yet been investigated.
