Increased perivascular fibrosis and pro-fibrotic cellular transition in intramyocardial blood vessels in myocardial infarction patients.

Background And Objectives: Structural and functional changes in the intramyocardial microcirculation increase the risk of myocardial infarction (MI). This study investigated intramyocardial perivascular fibrosis and pro-fibrotic cellular transitions in deceased acute and subacute MI patients to explore their involvement in the pathogenesis of MI.

Methods: Left ventricular tissue (LV) was obtained from the infarction area of autopsied patients with acute-phase MI (3-6 h;  = 24), subacute-phase MI (5-14 days;  = 12), and noninfarcted controls ( = 14).

How well does the academic performance of Ethiopian anaesthetists predict their National Licensing Examination scores: a cross-sectional study.

Objectives: This study assessed the relationship between academic performance and National Licensing Examination (NLE) scores of Ethiopian anaesthetists and proposed academic performance thresholds that predict failing the NLE.

Design: A retrospective cross-sectional study.

Setting: Academic performance measures were collected from eight universities and matched to total and subdomain NLE scores for anaesthetists.

A balancing act: integrating the expertise of youth peer workers in child and adolescent mental health services.

The socio-relational focus of youth peer support workers (YPSWs) poses a challenge when YPSWs are embedded in medical oriented contexts common to child and adolescent mental health services (CAMHS); as it requires YPSWs to find a balance between being a peer on one hand, and adhering to professional boundaries and medical standards set out by CAMHS on the other. To create a suitable position for YPSWs in CAMHS, this study investigated the unique socio-relational contributions YPSWs can make to CAMHS in addition to clinicians, and identified how these contributions can be embedded within CAMHS. This study reports on 37 semi-structured interviews conducted in the Netherlands with youth (n = 10), YPSWs (n = 10), and clinicians (n = 17).

How far should I manage acute optic neuritis as an ophthalmologist? A United Kingdom perspective.

Optic neuritis (ON) is an inflammation of or around the optic nerve, frequently caused by infectious or immune-mediated inflammatory disorders. In the UK, its strongest association is with Multiple Sclerosis (MS), though the combined prevalence of other associated infectious and immune-mediated inflammatory diseases (I-IMID) is similar to that of MS-ON. Prompt identification and understanding of ON's underlying cause informs tailored management and prognosis.

Pro-inflammatory T cells-derived cytokines enhance the maturation of the human fetal intestinal epithelial barrier.

Small intestine (SI) maturation during early life is pivotal in preventing the onset of gut diseases. In this study we interrogated the milestones of SI development by gene expression profiling and ingenuity pathway analyses. We identified a set of cytokines as main regulators of changes observed across different developmental stages.

Does higher performance in a national licensing examination predict better quality of care? A longitudinal observational study of Ethiopian anesthetists.

Background: Ethiopia made a national licensing examination (NLE) for associate clinician anesthetists a requirement for entry into the practice workforce. However, there is limited empirical evidence on whether the NLE scores of associate clinicians predict the quality of health care they provide in low-income countries. This study aimed to assess the association between anesthetists' NLE scores and three selected quality of patient care indicators.

The short- and longer-term effects of brief behavioral parent training versus care as usual in children with behavioral difficulties: study protocol for a randomized controlled trial.

Background: The access to and uptake of evidence-based behavioral parent training for children with behavioral difficulties (i.e., oppositional, defiant, aggressive, hyperactive, impulsive, and inattentive behavior) are currently limited because of a scarcity of certified therapists and long waiting lists.

Association between early postoperative hypoalbuminaemia and outcome after orthotopic heart transplantation.

Objectives: In patients undergoing heart transplantation (HTX), preoperative liver impairment and consecutive hypoalbuminaemia are associated with increased mortality. The role of early postoperative hypoalbuminaemia after HTX is unclear. This study investigated the association between early postoperative hypoalbuminaemia and 1-year mortality as well as 'days alive and out of hospital' (DAOH) after HTX.

Willingness for Medical Screening in a Dental Setting-A Pilot Questionnaire Study.

An important way to manage noncommunicable diseases (NCDs) is to focus on prevention, early detection, and reducing associated risk factors. Risk factors can be detected with simple general health checks, which can also be performed in dental clinics. The purpose of this study was to investigate participants' willingness to participate in general health checks at the dentist, in particular the difference in opinion between medical patients and random healthy dental attendees.

Ethiopian Anesthetist Licensing Examination: A Qualitative Study of Concerns and Unintended Consequences.

Background: Ethiopia increased its anesthesia workforce drastically by expanding the training of associate clinician anesthetists. Following this expansion, the Ministry of Health established an entry-level anesthesia licensing examination to ensure patient safety. However, there is limited empirical evidence on the impacts of licensing exams in low- and middle-income countries.

Diagnosis of childhood febrile illness using a multi-class blood RNA molecular signature.

Background: Appropriate treatment and management of children presenting with fever depend on accurate and timely diagnosis, but current diagnostic tests lack sensitivity and specificity and are frequently too slow to inform initial treatment. As an alternative to pathogen detection, host gene expression signatures in blood have shown promise in discriminating several infectious and inflammatory diseases in a dichotomous manner. However, differential diagnosis requires simultaneous consideration of multiple diseases.

Relationship between molecular pathogen detection and clinical disease in febrile children across Europe: a multicentre, prospective observational study.

Background: The PERFORM study aimed to understand causes of febrile childhood illness by comparing molecular pathogen detection with current clinical practice.

Methods: Febrile children and controls were recruited on presentation to hospital in 9 European countries 2016-2020. Each child was assigned a standardized diagnostic category based on retrospective review of local clinical and microbiological data.

The Ethiopian Anesthetist Licensing Examination and Associated Improvement in in-School Student Performance: A Retrospective Study.

Background: Ethiopia introduced a national licensing examination (NLE) in response to growing concerns about the competence of graduates and the quality of education. This study aimed to assess the associated in-school student performance changes in anesthetist training programs following NLE implementation.

Methods: Academic records of 1493 graduate anesthetists were retrospectively obtained from eight universities before (n=932) and after (n=561) NLE implementation.

Treating children's aggressive behavior problems using cognitive behavior therapy with virtual reality: A multicenter randomized controlled trial.

Does Mind-Wandering Explain ADHD-Related Impairment in Adolescents?

Currently, diagnostic criteria for ADHD mainly reflect behavioral symptoms, neglecting internal phenomena like mind-wandering. Recent studies found that mind-wandering explains impairment beyond ADHD symptoms in adults. To better capture ADHD-related impairment in adolescents, we aimed to elucidate whether mind-wandering is associated with impairments that are prevalent in adolescents (i.

IFT74 variants cause skeletal ciliopathy and motile cilia defects in mice and humans.

Motile and non-motile cilia play critical roles in mammalian development and health. These organelles are composed of a 1000 or more unique proteins, but their assembly depends entirely on proteins synthesized in the cell body and transported into the cilium by intraflagellar transport (IFT). In mammals, malfunction of non-motile cilia due to IFT dysfunction results in complex developmental phenotypes that affect most organs.

Efficient complement-mediated clearance of immunosuppressed T cells by macrophages.

Cancer is one of the leading causes of death worldwide. Treatment outcome is largely dictated by the tumor type, disease stage, and treatment success rates, but also by the variation among patients in endogenous anti-tumor responses. Studies indicate that the presence of neutrophils in the tumor microenvironment is associated with a worse patient outcome due to their ability to suppress local anti-tumor T cell activity.

Analysis of movements in tooth removal procedures using robot technology.

Being one of the oldest en most frequently performed invasive procedures; the lack of scientific progress of tooth removal procedures is impressive. This has most likely to do with technical limitations in measuring different aspects of these keyhole procedures. The goal of this study is to accurately capture the full range of motions during tooth removal as well as angular velocities in clinically relevant directions.
