Children and Restraints Study in Emergency Ambulance Transport-Cardiopulmonary Resuscitation (CARSEAT-CPR): An Observational Cohort Study of a Simulated Pediatric Cardiac Arrest.

Objectives: To compare the ability to perform basic life support (BLS) skills on children and infants in a moving ambulance whether or not they are properly secured to the stretcher.

Methods: Emergency Medicine Services provider ability to perform BLS skills was measured in moving ambulances on a closed course using an analog for child and infant cardiac arrest. Data were compared for child and infant manikins secured to the stretcher via different methods in simulated patient resuscitations performed by 24 participants.

Pathogenic proteotoxicity of cryptic splicing is alleviated by ubiquitination and ER-phagy.

RNA splicing enables the functional adaptation of cells to changing contexts. Impaired splicing has been associated with diseases, including retinitis pigmentosa, but the underlying molecular mechanisms and cellular responses remain poorly understood. In this work, we report that deficiency of ubiquitin-specific protease 39 (USP39) in human cell lines, zebrafish larvae, and mice led to impaired spliceosome assembly and a cytotoxic splicing profile characterized by the use of cryptic 5' splice sites.

Variations in antenatal management and outcomes in haemolytic disease of the fetus and newborn: an international, retrospective, observational cohort study.

Background: Advances in haemolytic disease of the fetus and newborn have led to numerous treatment options. We report practice variations in the management and outcomes of haemolytic disease of the fetus and newborn in at-risk pregnancies.

Methods: In this international, retrospective, observational cohort study, data from cases with moderate or severe haemolytic disease of the fetus and newborn were retrieved from 31 centres in 22 countries.

Ebeiedinone and peimisine inhibit cigarette smoke extract-induced oxidative stress injury and apoptosis in BEAS-2B cells.

Ebeiedinone and peimisine are the major active ingredients of Fritillariae Cirrhosae Bulbus. In this study, we looked at how these two forms of isosteroidal alkaloids protect human bronchial epithelial BEAS-2B cells from oxidative stress and apoptosis caused by cigarette smoke extract (CSE). First, the cytotoxicity was determined using the CCK8 assay, and an oxidative stress model was established.

Imaging of dorsal wrist pain.

Pain on the dorsal side of the wrist is a common clinical presentation, comparable to pain experienced on the ulnar and radial aspects of the wrist. The dorsal wrist region has distinct anatomical features and is associated with a wide spectrum of pathologies, including conditions affecting the bones, cartilage, ligaments, and tendons. Accurate diagnosis often depends on imaging techniques such as radiographs and ultrasound, with a growing trend towards the use of magnetic resonance imaging (MRI) for more detailed assessment of complex cases.

Search for a Sub-eV Sterile Neutrino Using Daya Bay's Full Dataset.

This Letter presents results of a search for the mixing of a sub-eV sterile neutrino with three active neutrinos based on the full data sample of the Daya Bay Reactor Neutrino Experiment, collected during 3158 days of detector operation, which contains 5.55×10^{6} reactor ν[over ¯]_{e} candidates identified as inverse beta-decay interactions followed by neutron capture on gadolinium. The analysis benefits from a doubling of the statistics of our previous result and from improvements of several important systematic uncertainties.

Interaction of the intestinal cytokines-JAKs-STAT3 and 5 axes with RNA N6-methyladenosine to promote chronic inflammation-induced colorectal cancer.

Colorectal cancer (CRC) is one of the most common cancers, with a high mortality rate worldwide. Mounting evidence indicates that mRNA modifications are crucial in RNA metabolism, transcription, processing, splicing, degradation, and translation. Studies show that N6-methyladenosine (m6A) is mammalians' most common epi-transcriptomic modification.

Avoid the Peel: Citrus Fruit Bezoar Causing Intestinal Perforation.

We report a highly unusual case of small bowel obstruction in an 86-year-old man from ingestion of a citrus fruit, known as kumquats, which led to intestinal perforation and peritonitis. He initially presented with a one-day history of diffuse abdominal pain associated with nausea and feculent emesis after eating whole pieces of unpeeled kumquats. When symptoms of peritonitis evolved with a blood lactate of 5.

Roles and occurrences of microbiota in the osmoregulatory organs, gills and gut, in marine medaka upon hypotonic stress.

Gills and gut are the two primary osmoregulatory organs in fish. Recently, studies have expanded beyond the osmoregulatory mechanisms of these organs to explore the microbiota communities inhabiting them. It is now known that microbial communities in both organs shift in response to osmotic stress.

Screening for oncogenic AF1q expression predicts disease recurrence in gastric cancer patients.

AF1q associates with tumor progression and metastases upon WNT signaling. The downstream WNT target CD44 has demonstrated prognostic significance in gastric cancer (GC). This study evaluates the impact of AF1q on tumor stage and survival in GC patients.

Protective effect of the total alkaloid extract from Bulbus on cigarette smoke-induced Beas-2B cell injury model and transcriptomic analysis.

Background: Bulbus (BFP) is a traditional Chinese medicine that has long been used to treat lung diseases, but the active components and mechanism are still unclear.

Objective: This study aimed to investigate the effect and mechanism of the total alkaloid extract from BFP (BFP-TA) on cigarette smoke extract (CSE)-induced Beas-2B cells injury.

Design: The Beas-2B cells injury model was induced by 2% CSE, then the effect of BFP-TA on the levels of total antioxidant capacity (T-AOC), superoxide dismutase (SOD) and malondialdehyde (MDA) was detected according to the instructions of the T-AOC assay kit, the SOD detection kit and the MDA detection kit, and the production of ROS was detected by fluorescence microscopy.

Microplastic exposure disturbs sleep structure, reduces lifespan, and decreases ovary size in .

The organ-specific toxicity resulting from microplastic (MP) exposure has been extensively explored, particularly concerning the gut, liver, testis, and lung. However, under natural conditions, these effects are not restricted to specific organs or tissues. Investigating whether MP exposure presents a systemic threat to an entire organism, impacting factors such as lifespan, sleep, and fecundity, is essential.

Protective Effect of the Total Alkaloid Extract from Bulbus in a Mouse Model of Cigarette Smoke-Induced Chronic Obstructive Pulmonary Disease.

Purpose: In recent years, the incidence of chronic obstructive pulmonary disease (COPD) has been increasing year by year, but therapeutic drugs has no breakthrough. The total alkaloid extract from Bulbus (BFP-TA) is widely used in treating lung diseases. Therefore, this study aimed to investigate the protective effect and mechanism of BFP-TA in COPD mice.

Experimental congenital diaphragmatic hernia features an alteration of DNA sensing targets cGAS and STING.

Background: The pathogenesis of congenital diaphragmatic hernia (CDH) depends on multiple factors. Activation of the DNA-sensing cyclic-GMP-AMP-synthase (cGAS) and Stimulator-of-Interferon-Genes (STING) pathway by double-stranded DNA (dsDNA) links environmental stimuli and inflammation. We hypothesized that nitrofen exposure alters cGAS and STING in human bronchial epithelial cells and fetal rat lungs.

Assessing the generalisability of the psychosis metabolic risk calculator (PsyMetRiC) for young people with first-episode psychosis with validation in a Hong Kong Chinese Han population: a 4-year follow-up study.

Background: Metabolic syndrome (MetS) is common following first-episode psychosis (FEP), contributing to substantial morbidity and mortality. The Psychosis Metabolic Risk Calculator (PsyMetRiC), a risk prediction algorithm for MetS following a FEP diagnosis, was developed in the United Kingdom and has been validated in other European populations. However, the predictive accuracy of PsyMetRiC in Chinese populations is unknown.

Size-dependent deleterious effects of nano- and microplastics on sperm motility.

Introduction: Growing concerns regarding the reproductive toxicity associated with daily life exposure to micro-/nano-plastics (abbreviated as MNPs) have become increasingly prevalent. In reality, MNPs exposure involves a heterogeneous mixture of MNPs of different sizes rather than a single size.

Methods: In this study, an oral exposure mouse model was used to evaluate the effects of MNPs of four size ranges: 25-30 nm, 1-5 µm, 20-27 µm, and 125-150 µm.

Microplastics from face mask impairs sperm motility.

The COVID-19 pandemic has resulted in unprecedented plastic pollution from single-used personal protective equipment (PPE), especially face masks, in coastal and marine environments. The secondary pollutants, microplastics from face masks (mask MP), rise concern about their detrimental effects on marine organisms, terrestrial organisms and even human. Using a mouse model, oral exposure to mask MP at two doses, 0.

Are factor scores measurement invariant?

There has been increased interest in practical methods for integrative analysis of data from multiple studies or samples, and using factor scores to represent constructs has become a popular and practical alternative to latent variable models with all individual items. Although researchers are aware that scores representing the same construct should be on a similar metric across samples-namely they should be measurement invariant-for integrative data analysis, the methodological literature is unclear whether factor scores would satisfy such a requirement. In this note, we show that even when researchers successfully calibrate the latent factors to the same metric across samples, factor scores-which are estimates of the latent factors but not the factors themselves-may not be measurement invariant.
