Introduction: Airway management is a critical component of out-of-hospital cardiac arrest (OHCA) resuscitation. The primary aim of this study was to describe pre-hospital airway management in adult patients post-OHCA. Secondary aims were to investigate whether tracheal intubation (TI) versus use of supraglottic airway device (SGA) was associated with patients’ outcomes, including ventilator-free d

Background: Up-to-date estimates of stroke burden and attributable risks and their trends at global, regional, and national levels are essential for evidence-based health care, prevention, and resource allocation planning. We aimed to provide such estimates for the period 1990–2021. Methods: We estimated incidence, prevalence, death, and disability-adjusted life-year (DALY) counts and age-standard

Amplification of the MDM2 and CDK4 genes on chromosome 12 is commonly associated with low-grade osteosarcomas. In this study, we conducted high-resolution genomic and transcriptomic analyses on 33 samples from 25 osteosarcomas, encompassing both high- and low-grade cases with MDM2 and/or CDK4 amplification. We discerned four major subgroups, ranging from nearly intact genomes to heavily rearranged

Introduction: Exposure to environmental chemicals during fetal development may increase the risk of testicular germ cell cancer (TGCC), but few studies have tested the hypothesis. We focused on organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs), previously investigated in relation to other male reproductive health outcomes. Methods: We conducted a nested case-control study of 33

BACKGROUND: Risk stratification tools for paediatric community-acquired pneumonia (CAP) in well-resourced settings are scarce. We prospectively developed models to predict CAP severity within a multinational cohort of paediatric emergency departments (EDs). Our primary objective was to develop a risk prediction model to discriminate between mild CAP and moderate or severe CAP to assist clinicians

Nitric oxide (NO) can modulate both tumor growth and antitumor immune responses. In order to elucidate the mechanism of curative therapeutic immunization with IFNgamma-producing glioma cells, we examined the expression of inducible nitric oxide synthase (iNOS) in tissue sections from immunized animals. There was a significantly enhanced iNOS expression both intratumorally and at the immunization s

Previous studies have demonstrated that in admixed populations, West African ancestry is associated with an increased prevalence of systemic lupus erythematosus (SLE). In the current study, the effect of Amerindian ancestry in SLE was examined in an admixed population in Argentina. The Argentine population is predominantly European with approximately 20% Amerindian admixture, and a very small (<2%

OBJECTIVES: The present study tested the hypothesis that treatment with human recombinant immunoglobulin G1 (IgG1) antibodies against a specific oxidized low-density lipoprotein (oxLDL) epitope will induce regression of existing atherosclerotic lesions in LDL receptor-deficient mice expressing apolipoprotein B-100 (apoB-100) (Apobec-1(-/-)/LDLR(-/-)). BACKGROUND: Oxidized LDL plays an essential ro

The dysregulated immune response and inflammation resulting in severe COVID-19 are still incompletely understood. Having recently determined that aberrant death-ligand-induced cell death can cause lethal inflammation, we hypothesized that this process might also cause or contribute to inflammatory disease and lung failure following SARS-CoV-2 infection. To test this hypothesis, we developed a nove

IMPORTANCE: In patients with clinically node-negative (cN0) breast cancer and 1 or 2 sentinel lymph node (SLN) macrometastases, omitting completion axillary lymph node dissection (CALND) is standard. High nodal burden (≥4 axillary nodal metastases) is an indication for intensified treatment in luminal breast cancer; hence, abstaining from CALND may result in undertreatment.OBJECTIVE: To develop a

Background: Combined CDK4/6 inhibitor (CDK4/6i) and endocrine therapy significantly improve the outcome of patients with advanced estrogen receptor-positive (ER+) breast cancer. However, resistance to this treatment and disease progression remains a major clinical challenge. High expression of the receptor tyrosine kinase REarranged during Transfection (RET) has been associated with resistance to

BackgroundThe lack of effective screening methods for the detection of ovarian cancer leads to late diagnosis and poor outcomes. High-grade serous ovarian carcinoma (HGSC) is strongly dominated by copy number alterations (CNAs), resulting from underlying mutational processes. Several studies have reported the detection of ovarian carcinoma-derived somatic mutations in cervical samples, uterine lav

We aim to characterize high-velocity (HiVel) stars in the solar vicinity both chemically and kinematically using the fourth data release of the RAdial Velocity Experiment (RAVE). We used a sample of 57 HiVel stars with Galactic rest-frame velocities larger than 275 km s(-1). With 6D position and velocity information, we integrated the orbits of the HiVel stars and found that, on average, they reac

BACKGROUND: HYPO-RT-PC is a phase 3 trial comparing ultra-hypofractionated and conventionally fractionated radiotherapy in intermediate-to-high-risk localised prostate cancer. This 10-year update reports long-term efficacy and toxicity outcomes.METHODS: In this open-label, randomised, phase 3, non-inferiority trial done in ten centres in Sweden and two in Denmark, we recruited men aged 75 years or

Background: Ambulatory oxygen therapy can be used to treat exertional hypoxaemia during daily life activities in people with fibrotic interstitial lung disease (ILD). However, evidence for its efficacy is scarce. This trial aimed to compare the effects of ambulatory oxygen with ambulatory air on physical activity in daily life over 6 months in people with fibrotic ILD and isolated exertional hypox

Background: Postoperative lymph node irradiation can affect shoulder morbidity in breast cancer patients, yet widely accepted dose-volume constraints for the shoulder joint are lacking. The SENOMAC trial randomized patients with breast cancer and 1–2 sentinel lymph node (SLN) macrometastases to axillary lymph node dissection (ALND) or SLN biopsy only. We aimed to analyze the association between th

Introduction: Synovial fibroblasts (S-Fib) are recognized as key drivers of joint inflammation in adult arthritis. Moreover, data are limited on the processes driving monocyte activation in oligoarticular juvenile idiopathic arthritis (oJIA). Therefore, we aimed to explore if S-Fib from patients with oJIA induce monocyte activation. Methods: S-Fib were isolated from the synovial fluid (SF) of n =

Nature provides us with a vast source of inspiration. However, given industrial designers' open-mindedness and inquisitiveness, a surprisingly limited set of nature-derived symbols continues to be popular in this creative discipline. Rather than designing products mimicking nature, it is probably more rewarding designing them based on the natural principles leading to its growth and form. However,

Context: Polymorphisms in genes involved in regulation, biosynthesis, metabolism, and actions of testicular sex hormones may influence hormone balance and phenotype of aging men. Objective: We investigated the relationships between polymorphisms in genes related to pituitary-testicular endocrine function and health status. Design and Setting: Using cross-sectional baseline data, we conducted a mul
