Pets and related allergens modify the association between early life DEHP exposure and respiratory outcomes in children.

Introduction: Throughout the perinatal period children are exposed to complex mixtures, including indoor chemicals such as phthalates, and biological agents. However, few studies focus on interactions between early-life co-exposures to shed light on how co-exposures modify their individual effects. Therefore, our study aims to assess whether early-life exposure to pets and related biological agents, namely pet allergens and endotoxin, modifies the association between di-(2-ethylhexyl) phthalate (DEHP) and asthma and wheeze in preschoolers to gain insight into interactions.

A Prediction Model to Identify Clinically Relevant Medication Discrepancies at the Emergency Department (MED-REC Predictor): Development and Validation Study.

Background: Many patients do not receive a comprehensive medication reconciliation, mostly owing to limited resources. We hence need an approach to identify those patients at the emergency department (ED) who are at increased risk for clinically relevant discrepancies.

Objective: The aim of our study was to develop and externally validate a prediction model to identify patients at risk for at least 1 clinically relevant medication discrepancy upon ED presentation.

Confocal Microscopy Analysis of Protein Sorting to Plasmodesmata in Nicotiana benthamiana.

Plasmodesmata are membranous nanopores that connect the cytoplasm of adjacent plant cells and enable the cell-to-cell trafficking of nutrients, macromolecules, as well as invading viruses. Plasmodesmata play fundamental roles in the regulation of intercellular communication, contributing to plant development, environmental responses, and interactions with viral pathogens. Discovering plasmodesmal localization of plant or viral proteins could provide useful functional information about the protein and is important for understanding the mechanisms of plant-virus interactions.

Symptomatology and Management of Adult Anaphylaxis according to Trigger: A Cross-Sectional Study.

Introduction: Anaphylaxis is an acute life-threatening allergy, most commonly provoked by food, venom, or drugs. There is limited data regarding differences in symptomatology between anaphylaxis provoked by different triggers. This study aimed to assess sociodemographic characteristics, clinical symptoms, and management of anaphylaxis, according to triggers in adults.

Impact of postpartum hospital length of stay on infant gut microbiota: a comprehensive analysis of vaginal and caesarean birth.

Background: The primary concern with prolonged hospitalization following birth is the risk of acquiring hospital-acquired infections (HAIs) caused by opportunistic bacteria, which can alter the early establishment of gut microbiota.

Objective: To assess the association between postpartum hospital length of stay (LOS) and the composition of gut microbiota at 3 and 12 months of age according to birth mode.

Methods: In total, 1313 Canadian infants from the CHILD Cohort Study were involved in this study.

Management of anaphylaxis after pre-hospital epinephrine use in children with food-induced anaphylaxis.

Background: Previous guidelines recommend prompt epinephrine administration, followed by observation in the emergency department (ED). The need for transfer in all cases of anaphylaxis has recently been challenged.

Objective: To evaluate the need for additional ED treatment among children with anaphylaxis who received prehospital epinephrine.

The Impact of the COVID-19 Pandemic on the Cost of the Urology Application Process.

Objective: To review the self-reported costs of urology residency applications from 2019 to 2023 and examine the impact of Society of Academic Urologists (SAU) policy changes made during the COVID-19 pandemic on these costs.

Methods: Data from the Texas Seeking Transparency in Applications to Residency (STAR) survey were used to evaluate costs incurred by fourth-year urology residency applicants from U.S.

The actin-spectrin submembrane scaffold restricts endocytosis along proximal axons.

Clathrin-mediated endocytosis has characteristic features in neuronal dendrites and presynapses, but how membrane proteins are internalized along the axon shaft remains unclear. We focused on clathrin-coated structures and endocytosis along the axon initial segment (AIS) and their relationship to the periodic actin-spectrin scaffold that lines the axonal plasma membrane. A combination of super-resolution microscopy and platinum-replica electron microscopy on cultured neurons revealed that AIS clathrin-coated pits form within "clearings", circular areas devoid of actin-spectrin mesh.

Enhancing HIV treatment and support: a qualitative inquiry into client and healthcare provider perspectives on differential service delivery models in Uganda.

Background: HIV/AIDS continues to be a significant contributor to illness and death, particularly in sub-Saharan Africa. In this study, we conducted a qualitative assessment to understand Client and Healthcare Provider Perspectives on Differential Service Delivery Models in Uganda. The purpose was to establish strengths and weaknesses within the services delivery models, inform policy and decision-making, and to facilitate context specific solutions.

Consistent cord blood DNA methylation signatures of gestational age between South Asian and white European cohorts.

Background: Epigenetic modifications, particularly DNA methylation (DNAm) in cord blood, are an important biological marker of how external exposures during gestation can influence the in-utero environment and subsequent offspring development. Despite the recognized importance of DNAm during gestation, comparative studies to determine the consistency of these epigenetic signals across different ethnic groups are largely absent. To address this gap, we first performed epigenome-wide association studies (EWAS) of gestational age (GA) using newborn cord blood DNAm comparatively in a white European (n = 342) and a South Asian (n = 490) birth cohort living in Canada.
