Differential effects of gestational Cannabis smoke and phytocannabinoid injections on male and female rat offspring behavior.

Our understanding of the implications of gestational Cannabis exposure (GCE) remains unclear as Cannabis use increases worldwide. Much of the existing knowledge of the effects of GCE has been gained from preclinical experiments using injections of isolated Δ-tetrahydrocannabinol (THC) at relatively high doses. Few investigations of the effects of GCE to smoke from the whole Cannabis flower have been conducted, despite this being the most common mode of human consumption.

Safety and feasibility of 3D-electroanatomical mapping-guided zero or near-zero fluoroscopy catheter ablation for pediatric arrhythmias: Meta-analysis.

Background: Catheter ablation in the pediatric population using fluoroscopy has been known to cause adverse events. This study aims to assess the effectiveness and safety of zero fluoroscopy (ZF) and near-ZF-guided catheter ablation for the treatment of arrhythmias in the pediatric population.

Methods: The PubMed, Embase, and Cochrane library databases were searched and reviewed for relevant studies.

Long-term outcomes of ventricular tachycardia ablation in repaired tetralogy of Fallot: Systematic review and meta-analysis.

Background: Ventricular tachycardia (VT) remains a risk in repaired Tetralogy of Fallot (rTOF); however, long-term benefits of VT ablation have not been established. This study compares the outcomes of rTOF patients with and without VT ablation.

Methods: We searched multiple databases examining the outcomes of rTOF patients who had undergone VT ablation compared to those without ablation.

The Global Impact of Multisystemic Vulnerabilities on Criminal Variety: A Cross-Continental Study in Young Adults.

Previous research has shown a robust association between different childhood and adolescent vulnerabilities and youth offending. However, these investigations have primarily focused on youths from high-income Western countries. Consequently, the generalizability of these findings to better inform global justice policies remains uncertain.

Prognostic Value of Baseline Echocardiographic Parameters in Heart Failure With Improved vs Nonrecovered Ejection Fraction.

Background: Ejection fraction (EF) is often used as a prognostic indicator and for classifying heart failure (HF) patients. This study evaluates the association of echocardiographic parameters with HF with improved EF (HFimpEF).

Methods: This single-centre study retrospectively included patients with HF with reduced EF (HFrEF) from a cohort of admitted patients over 2018-2020, who were then followed up prospectively until 2023.

Future direction of substrate-based catheter ablation in Brugada syndrome and other inherited primary arrhythmia syndromes: Systematic review and meta-analysis.

Background: Inherited Primary Arrhythmias Syndromes (IPAS), especially Brugada syndrome (BrS), have been associated with arrhythmogenic substrates that can be targeted through ablation. This meta-analysis evaluated the outcomes of catheter ablation (CA) in different types of IPAS based on procedural guidance and location.

Methods: A systematic search was conducted across multiple databases to identify studies reporting on ventricular arrhythmia (VA) events before and after CA in IPAS, including BrS, Long-QT syndrome (LQTS), Early repolarization syndrome (ERS), and Idiopathic ventricular fibrillation (IVF).

High-THC Smoke Impairs Incidental Memory Capacity in Spontaneous Tests of Novelty Preference for Objects and Odors in Male Rats.

Working memory is an executive function that orchestrates the use of limited amounts of information, referred to as working memory capacity, in cognitive functions. exposure impairs working memory in humans; however, it is unclear whether facilitates or impairs rodent working memory and working memory capacity. The conflicting literature in rodent models may be at least partly because of the use of drug exposure paradigms that do not closely mirror patterns of human use.

The NeuroBel: A Screening Test for Verbal Language Impairment in Spanish-Speaking Elderly People With Cognitive Decline.

Purpose: The NeuroBel is a short test that can detect cognitive decline using language tasks. This study replicated previous research using larger clinical samples from three Spanish-speaking countries.

Method: Eight tasks were used to analyze verbal language functioning using a psycholinguistic approach.

A genome-wide genetic screen identifies CYRI-B as a negative regulator of CEACAM3-mediated phagocytosis.

Opsonin-independent phagocytosis mediated by human carcinoembryonic antigen-related cell adhesion molecule 3 (CEACAM3) has evolved to control a subset of human-restricted bacterial pathogens. CEACAM3 engagement triggers rapid GTP-loading of the small GTPase Rac as a master regulator of cytoskeletal rearrangements and lamellipodia-driven internalization. To identify components of the CEACAM3-initiated signaling cascade, we performed a genome-wide CRISPR/Cas9-based screen in human myeloid cells.

Longitudinal Structural and Diffusion-Weighted Neuroimaging of Young Children Born Preterm.

Background: Children born preterm are at risk for diffuse injury to subcortical gray and white matter.

Methods: We used a longitudinal cohort study to examine the development of subcortical gray matter and white matter volumes, and diffusivity measures of white matter tracts following preterm birth. Our participants were 47 children born preterm (24 to 32 weeks gestational age) and 28 children born at term.

Scalable detection of technically challenging variants through modified next-generation sequencing.

Background: Some clinically important genetic variants are not easily evaluated with next-generation sequencing (NGS) methods due to technical challenges arising from high- similarity copies (e.g., PMS2, SMN1/SMN2, GBA1, HBA1/HBA2, CYP21A2), repetitive short sequences (e.

Phagocytosis mediated by the human granulocyte receptor CEACAM3 is limited by the receptor-type protein tyrosine phosphatase PTPRJ.

Carcinoembryonic antigen-related cell adhesion molecule 3 (CEACAM3) is a human granulocyte receptor mediating the efficient phagocytosis of a subset of human-restricted bacterial pathogens. Its function depends on phosphorylation of a tyrosine-based sequence motif, but the enzyme(s) responsible for reversing this modification are unclear. Here, we identify the receptor-type protein tyrosine phosphatase PTPRJ as a negative regulator of CEACAM3-mediated phagocytosis.

Driving behaviour and visual compensation in glaucoma patients: Evaluation on a driving simulator.

Background: To assess the driving performance and both the visual scanning and driving compensations of glaucoma patients.

Methods: In this case-control pilot study, the driving behaviour and performance of 14 patients with glaucoma and nine healthy age- and sex-similar control subjects were compared in a fixed-base driving simulator. All subjects performed in four scenarios with one to two hazardous situations on urban streets, for a total of five hazards.

The global impact of adverse childhood experiences on criminal behavior: A cross-continental study.

Background: Adverse Childhood Experiences (ACEs) have been associated with a greater risk of later criminal offending. However, existing research in this area has been primarily conducted in Western developed countries and cross-cultural studies are rare.

Objectives: This study examined the relationship between ACEs and criminal behaviors in young adults living in 10 countries located across five continents, after accounting for sex, age, and cross-national differences.

A Practical Approach to Monitoring Biomarkers of Inflammation and Muscle Damage in Youth Soccer Players During a 6-Month Training Cycle.

The aim of the study was to determine the effects of a 6-month training cycle on muscle damage and inflammatory markers in youth male soccer players. Twenty-one soccer players were tested four times: at the beginning (T1) and immediately after the pre-season period (T2), in the middle (T3) and at the end of the competitive period (T4). Muscle damage and inflammatory markers were determined in blood taken 36 hours after the match.

Self-regulation task in young school age children born preterm: Correlation with early academic achievement.

Background: Children born preterm are at risk for difficulties in executive function (EF), however there are limited tools to assess EF in young children and it is not fully understood how these early deficits are related to emerging academic skills.

Aims: To examine (a) early EF differences in young children born preterm, (b) how a measure of behavioral self-regulation correlates with other measures of EF in children born preterm, and (c) how this measure relates to academic outcomes in children born preterm.

Study Design: Longitudinal cohort study.

A Hybrid Tracking System of Full-Body Motion Inside Crowds.

For our understanding of the dynamics inside crowds, reliable empirical data are needed, which could enable increases in safety and comfort for pedestrians and the design of models reflecting the real dynamics. A well-calibrated camera system can extract absolute head position with high accuracy. The inclusion of inertial sensors or even self-contained full-body motion capturing systems allows the relative tracking of invisible people or body parts or capturing the locomotion of the whole body even in dense crowds.

Effects of home confinement on mental health and lifestyle behaviours during the COVID-19 outbreak: insights from the ECLB-COVID19 multicentre study.

Although recognised as effective measures to curb the spread of the COVID-19 outbreak, social distancing and self-isolation have been suggested to generate a burden throughout the population. To provide scientific data to help identify risk factors for the psychosocial strain during the COVID-19 outbreak, an international cross-disciplinary online survey was circulated in April 2020. This report outlines the mental, emotional and behavioural consequences of COVID-19 home confinement.

Very Low Prevalence and Incidence of Atrial Fibrillation among Bolivian Forager-Farmers.

Background: Atrial fibrillation is the most common arrhythmia in post-industrialized populations. Older age, hypertension, obesity, chronic inflammation, and diabetes are significant atrial fibrillation risk factors, suggesting that modern urban environments may promote atrial fibrillation.

Objective: Here we assess atrial fibrillation prevalence and incidence among tropical horticulturalists of the Bolivian Amazon with high levels of physical activity, a lean diet, and minimal coronary atherosclerosis, but also high infectious disease burden and associated inflammation.

Rapidly declining body temperature in a tropical human population.

Normal human body temperature (BT) has long been considered to be 37.0°C. Yet, BTs have declined over the past two centuries in the United States, coinciding with reductions in infection and increasing life expectancy.

Expanded encyclopaedias of DNA elements in the human and mouse genomes.

The human and mouse genomes contain instructions that specify RNAs and proteins and govern the timing, magnitude, and cellular context of their production. To better delineate these elements, phase III of the Encyclopedia of DNA Elements (ENCODE) Project has expanded analysis of the cell and tissue repertoires of RNA transcription, chromatin structure and modification, DNA methylation, chromatin looping, and occupancy by transcription factors and RNA-binding proteins. Here we summarize these efforts, which have produced 5,992 new experimental datasets, including systematic determinations across mouse fetal development.
