Circumstances in a young German cohort with sudden cardiac arrest: systematic insights and implications.

Introduction: Data on circumstances of sudden cardiac arrest (SCA) in Germany are limited. The present study aimed to investigate systematically the current pre- and in-hospital circumstances of a SCA cohort at young age (65 years or younger) in Germany.

Methods: In the period from 2010 to 2021, we enrolled 191 consecutive patients with SCA at a university hospital in the Ruhr area, Germany.

The Diagnosis and Therapy of Osteoporosis in Gaucher Disease.

Gaucher disease is a rare lysosomal storage disorder characterized by the accumulation of glucocerebroside lipids within multiple organs due to a deficiency of the lysosomal enzyme (acid β-glucosidase). It is an inherited autosomal recessive disease. The onset of symptoms can vary depending on disease type and severity, with milder forms presenting in adulthood.

Diagnostic Accuracy of Breath Tests to Detect Pulmonary Tuberculosis: A Systematic Review.

Purpose: Tuberculosis (TB) is a highly contagious infection and one of the world's leading causes of death from a single infectious agent. Currently, TB diagnosis can be established via mycobacterial cultures, Acid Fast Bacilli smear and molecular studies. In the ever-evolving landscape of medical advancements, breath tests have shown considerable promise.

Timing of acute decompensated heart failure in patients with heart failure and mildly reduced ejection fraction.

This study investigates the prognosis of acute decompensated heart failure (ADHF) on admission (i.e., primary ADHF) as compared to ADHF onset during course of hospitalization (i.

Ravulizumab demonstrates long-term efficacy, safety and favorable patient survival in patients with paroxysmal nocturnal hemoglobinuria.

Ravulizumab is a second-generation complement component 5 (C5) inhibitor (C5i) approved for the treatment of paroxysmal nocturnal hemoglobinuria (PNH) following positive results from two pivotal trials in patients with PNH originally naive to C5i treatment and eculizumab-experienced patients with PNH. In both trials, after the 26week primary evaluation period, all patients received ravulizumab for up to 6 years. To report ravulizumab treatment outcomes in patients with PNH originally naive to C5i treatment and eculizumab-experienced patients with PNH treated for up to 6 years.

Clinical characteristics and BGA-optimized pretest probability of pulmonary embolism in the elderly.

Background: Pulmonary arterial embolism (PE) is not well characterized in elderly patients. In addition, unnecessary computed tomography pulmonary angiography (CTPA) examinations are often performed within this patient group, especially if the pretest probability is low.

Objective: To identify differences in clinical presentation in patients aged ≥80 years compared to patients <80 years and the effect of a BGA-optimized pretest probability to reduce unnecessary CTPAs according to age category.

Evolution of long scalp hair in humans.

The ability to grow long scalp hair is a distinct human characteristic. It probably originally evolved to aid in cooling the sun-exposed head, although the genetic determinants of long hair are largely unknown. Despite ancestral variations in hair growth, long scalp hair is common to all extant human populations, which suggests its emergence before or concurrently with the emergence of anatomically modern humans (AMHs), approximately 300 000 years ago.

Nonpharmacological Childhood Obesity Management in Denmark Reduces Steatotic Liver Disease and Obesity.

Steatotic liver disease (SLD) represents a multisystem disease and is a common complication of childhood obesity. We studied fat content at the abdominal level (liver, subcutaneous, and visceral) and the response to childhood obesity management. In this retrospective longitudinal study, 8-18-year-olds with a body mass index (BMI) z-score above 1.

Antiseizure medication use in acute symptomatic seizures: A narrative review.

Acute symptomatic seizures, occurring shortly after a central nervous system insult, constitute nearly half of all seizure cases. However, there is a conspicuous absence of clear, comprehensive, and cohesive guidelines for the management of these seizures with antiseizure medications, especially their duration of use. This lack of consensus on the optimal duration of therapy leads to prolonged treatments that may carry adverse consequences.

Mechanisms of increased pain discrimination by contingent reinforcement: a perceptual decision-making and instrumental learning account.

Recent evidence highlights that monetary rewards can increase the precision at which healthy human volunteers can detect small changes in the intensity of thermal noxious stimuli, contradicting the idea that rewards exert a broad inhibiting influence on pain perception. This effect was stronger with contingent rewards compared with noncontingent rewards, suggesting a successful learning process. In the present study, we implemented a model comparison approach that aimed to improve our understanding of the mechanisms that underlie thermal noxious discrimination in humans.

Aging platelets shift their hemostatic properties to inflammatory functions.

Platelets are crucial players in hemostasis and thrombosis, but also contribute to immune regulation and host defense, using different receptors, signaling pathways and effector functions, respectively. Whether distinct subsets of platelets specialize in these diverse tasks is insufficiently understood. Here, we employed an in vivo pulse-labelling method in Mus musculus models for tracking in vivo platelet ageing and its functional implications.

IL-1R1 and IL-18 Signals Regulate Mesenchymal Stromal Cells in an Aged Murine Model of Myelodysplastic Syndromes.

Myelodysplastic syndromes (MDS) are age-related diseases characterized by bone marrow (BM) dysfunction and an increased risk of developing acute leukemia. While there is growing evidence highlighting the crucial role of the BM microenvironment (BMME) in MDS, the specific influence of inflammation on BMME changes, as well as the potential benefits of targeting cytokines therapeutically, remain to be elucidated. We previously found interleukin-1 (IL-1) to be a driver of aging phenotypes of BMME and hematopoietic stem and progenitor cells (HSPCs).

CpG island methylator phenotype classification improves risk assessment in pediatric T-cell Acute Lymphoblastic Leukemia.

Current intensive treatment of pediatric T-cell acute lymphoblastic leukemia (T-ALL) has substantial side-effects, highlighting a need for novel biomarkers to improve risk stratification. Canonical biomarkers such as genetics and immunophenotype are largely not used in pediatric T-ALL stratification. This study aimed to validate the prognostic relevance of DNA methylation CpG island methylator phenotype (CIMP) risk stratification in two pediatric T-ALL patient cohorts: the Nordic NOPHO ALL2008 T-ALL study cohort (n=192) and the Dutch DCOG ALL-10/ALL-11 validation cohorts (n=156).

Two-layered immune escape in AML is overcome by Fcγ receptor activation and inhibition of PGE2 signaling in NK cells.

Loss of anticancer NK cell function in AML patients is associated with fatal disease progression and remains poorly understood. Here, we demonstrate that AML-blasts isolated from patients rapidly inhibit NK cell function and escape NK cell-mediated killing. Transcriptome analysis of NK cells exposed to AML-blasts revealed increased CREM expression and transcriptional activity, indicating enhanced cAMP signalling, confirmed by uniform production of the cAMP-inducing prostanoid PGE2 by all AML-blast isolates from patients.

Immunogenicity of the 9-valent human papillomavirus vaccine: Post hoc analysis from five phase 3 studies.

Post hoc analyses of 9-valent human papillomavirus (9vHPV) vaccine immunogenicity were conducted in five Phase 3 studies that enrolled males. Month 7 antibody geometric mean titers (GMTs) after three 9vHPV vaccine doses were analyzed in 10,024 males/females aged 16-26 years from studies 001 (NCT00543543), 002 (NCT00943722), 003 (NCT01651949), and 020 (NCT02114385). Covariates considered were age, gender, sexual orientation, region of residence, and race.

Randomised controlled feasibility trial of retroperitoneal vs transperitoneal robot-assisted partial nephrectomy: the ROPARN study.

Objectives: To assess the feasibility of trial recruitment and confirm that retroperitoneal robotic partial nephrectomy (RRPN) has the same oncological efficacy as transperitoneal robotic partial nephrectomy (TRPN), with time advantages and less peri-operative morbidity, in a randomised controlled trial (RCT).

Patients And Methods: The study was designed as a single-centre, open-label, feasibility RCT. Patients with suspected localised renal cell carcinoma referred for robotic partial nephrectomy were randomised in a 1:1 ratio to receive either TRPN or RRPN.
