Should We Worry About Conspiracy Theorists Rejecting Experts?

Concerns have been raised by both researchers and authorities regarding conspiracy theorists rejecting experts. To address the validity of these concerns, we need to delve into two key inquiries regarding who qualifies as an expert on conspiracy theories, and what constitutes an epistemically rational response (from a conspiracy theorist) when faced with expert testimony. The first inquiry present

Evaluation and comparison of patch materials used for pulmonary arterioplasty in pediatric congenital heart surgery

Objective: To evaluate the long-term performance of the patch materials we have used to augment the pulmonary arterial tree across a wide spectrum of diagnoses and anatomical locations. Methods: Retrospective, single-center review of 217 consecutive pediatric patients at a tertiary referral center from 1993 to 2020 who underwent patch arterioplasty of the pulmonary arterial tree from the pulmonary

Atrioventricular Area Difference Aids Diastolic Filling in Patients with Repaired Tetralogy of Fallot

A hydraulic force aids diastolic filling of the left ventricle (LV) and is proportional to the difference in short-axis area between the left ventricle and atrium; the atrioventricular area difference (AVAD). Patients with repaired Tetralogy of Fallot (rToF) and pulmonary regurgitation (PR) have reduced LV filling which could lead to a negative AVAD and a hydraulic force impeding diastolic filling

Increasing plasma calprotectin (S100A8/A9) is associated with 12-month mortality and unfavourable functional outcome in critically ill COVID-19 patients

BACKGROUND: Calprotectin (S100A8/A9) is a pro-inflammatory mediator primarily released from neutrophils. Previous studies have revealed associations between plasma calprotectin, disease severity and in-hospital mortality in unselected COVID-19 patients.OBJECTIVE: We aimed to assess whether plasma calprotectin dynamics during the first week of intensive care are associated with mortality and functi

Atrial septal defect in children : The incidence and risk factors for diagnosis

Objective: Secundum atrial septal defect (ASD II) is a common congenital heart defect, and interatrial communications among preterm children is even more common. The objective of this study was to calculate the incidence of ASD II in children, with assessment to gestational age at birth. Further, to assess maternal, prenatal and postnatal risk factors associated with ASD II among children of diffe

Short-term clinical follow-up of the treatment of aortic coarctation with a new generation of device

Coarctation of the aorta is a congenital heart anomalyinvolving constriction of an aortic segment, associated with wall thickening of media and the formationof overlapping infolding of neointimal tissue. For thefirst time it was described by Morgagni in 1760. Thispathology represents 5% -7% of all congenital heartdiseases, with an incidence of approximately 3 casesto 10 000 neonates1. The typical

Adverse events within 1 year after surgical and percutaneous closure of atrial septal defects in preterm children

Introduction: Atrial septal defect is the third most common CHD. A hemodynamically significant atrial septal defect causes volume overload of the right side of the heart. Preterm children may suffer from both pulmonary and cardiac comorbidities, including altered myocardial function. The aim of this study was to compare the rate of adverse events following atrial septal defect closure in preterm-

Cardiovascular Simulation as a Decision Support Tool

The variable presentation of clinical disease in pediatric patients with congenital and acquired heart disease makes standardized care challenging. This is further enforced by the ongoing growth and remodeling of the heart and vasculature in the individual child and the multitude of available treatment options. The clinical challenge is rather to individualize treatment based on all available info

Ceramides : a potential cardiovascular biomarker in young adult childhood cancer survivors?

Aims The aim of this study was to investigate circulating ceramides involved in cardiovascular disease (CVD) in young adult childhood cancer survivors (CCS) and their correlations to previously reported adverse cardiovascular changes in this cohort. Methods Fifty-seven CCS and 53 healthy controls (age 20-30 years) were studied. Plasma long-chain ceramides, known to be cardi- and results otoxic (C1

Early appearance of thyroid autoimmunity in children followed from birth for type 1 diabetes risk

PURPOSE: Autoantibodies to thyroid peroxidase (TPOAb) and thyroglobulin (TgAb) define pre-clinical autoimmune thyroid disease (AITD) which can progress to either clinical hypo- or hyperthyroidism. We determined the age at seroconversion in children genetically at risk for type 1 diabetes.METHODS: TPOAb and TgAb seropositivity were determined in 5066 healthy children with HLA DR3 or DR4 containing

Complete solubilization of mammalian cells in lysates

In conventional cell lysate protocols, cell debris is typically discarded to obtain a cleaner lysate. However, this approach has limitations, as it may overlook vital cellular components. By discarding cell debris, researchers may inadvertently exclude crucial elements. Retaining all cellular components offers several advantages for studying molecular biology within various cellular compartments.

Can tests of physical fitness predict traumatic knee injury in youth female athletes? A prospective cohort study

Objectives To compile a battery of test including various aspects of physical fitness that could be used on the field and to assess whether any of these tests are associated with future traumatic knee injuries in youth female team sports athletes. Design Prospective cohort. Setting Sport setting. Participants Female athletes (n = 117, age 15–19 years), from Swedish sport high schools, active in so

Generating Executable Test Scenarios from Autonomous Vehicle Disengagements using Natural Language Processing

With the emergence of autonomous vehicles comes requirements on adequate and rigorous testing techniques, particularly as systems continuously adapt to changing environments. Scenario-based, simulated testing is one approach that has received attention, where deriving relevant scenarios from various sources is still a challenge. We therefore explore creating executable test scenarios from textual

Global, regional, and national burden of gout, 1990-2020, and projections to 2050 : a systematic analysis of the Global Burden of Disease Study 2021

BACKGROUND: Gout is an inflammatory arthritis manifesting as acute episodes of severe joint pain and swelling, which can progress to chronic tophaceous or chronic erosive gout, or both. Here, we present the most up-to-date global, regional, and national estimates for prevalence and years lived with disability (YLDs) due to gout by sex, age, and location from the Global Burden of Diseases, Injuries

Investigation of engine performance for alcohol/kerosene blends as in spark-ignition aviation piston engine

Spark-ignition (SI) aviation piston engines are widely used on light helicopters and unmanned aerial vehicles (UAVs) because of the high-power density and ultra-high cost performance. Kerosene with high flash point is expected to improve safety of aforementioned aircrafts by replacing gasoline. However, in spark-ignition mode, kerosene is difficult to mix and is easy to knock. Short-chain alcohols
