Solid-phase red cell adherence versus gel column agglutination: Is there any difference for the detection of alloantibodies associated with the JK system?

Background: Detection of alloantibodies associated with the JK system may be tricky. They are nevertheless associated with transfusion reactions and their detection is crucial.

Study Design And Methods: Retrospectively and over a period of 7 years, we compared the results obtained using two different assays for antibody detection.

Key Competencies in Emergency Medicine Training in Belgium: A New Criteria-Based Evaluation Strategy.

Background In French-speaking Belgium, Emergency Medicine (EM) has been a recognized professional qualification for the last two decades. Currently, there is no consensus on the core competencies required for EM postgraduates. During the six-year training period, the acquisition of technical skills (scientific knowledge and technical procedures) is emphasized, but little account is taken regarding the development of non-technical skills such as communication, collaboration, leadership, and professionalism.

Cluster analysis identifies long COVID subtypes in Belgian patients.

Severe acute respiratory syndrome coronavirus infection presents complications known as long COVID, a multisystemic organ disease which allows multidimensional analysis. This study aims to uncover clusters of long COVID cases and establish their correlation with the clinical classification developed at the Clinical Research Unit of Brugmann University Hospital, Brussels. Such an endeavour is instrumental in customizing patient management strategies tailored to the unique needs of each distinct group.

Blood-based circulating biomarkers for prediction of immune-checkpoint inhibitors efficacy in renal cell carcinoma.

Immune checkpoint inhibitors (ICI)-based combinations have become the standard first-line treatment for advanced clear cell renal cell carcinoma (ccRCC). Despite significant improvements in survival and the achievement of sustained long-term responses, a subset of patients remains refractory to ICI, and most will eventually develop resistance. Thus, identifying predictive biomarkers for ICI efficacy and resistance is essential for optimizing therapeutic strategies.

Chronotype Differences and Symptom Network Dynamics of Post-Pandemic Sleep in Adolescents and Young Adults.

Social restrictions during the COVID-19 pandemic resulted in altered sleep patterns and mental health challenges, particularly among adolescents and young adults. Our objective was to examine the potential difference in insomnia prevalence and sleep patterns in this population between the first COVID-19 lockdown and the post-lockdown period, with a focus on chronotype. Additionally, we explored the network of sleep-related differences between these two periods.

Bismuth-based quadruple therapy versus standard triple therapy for the eradication of Helicobacter pylori in Belgium: a multicentre, non-blinded randomized, prospective study.

Background: Helicobacter pylori (Hp) infection predisposes to malignant and non-malignant diseases warranting eradication. In Belgium, resistance rates for clarithromycin demonstrate regional variations making the use of standard triple therapy (STT) borderline acceptable. According to a recent Belgian survey, STT and bismuth-based quadruple therapy (BQT), are equally frequent prescribed as first line treatment for treatment naïve Hp positive patients.

Transfer Learning Video Classification of Preserved, Mid-Range, and Reduced Left Ventricular Ejection Fraction in Echocardiography.

Identifying patients with left ventricular ejection fraction (EF), either reduced [EF < 40% (rEF)], mid-range [EF 40-50% (mEF)], or preserved [EF > 50% (pEF)], is considered of primary clinical importance. An end-to-end video classification using AutoML in Google Vertex AI was applied to echocardiographic recordings. Datasets balanced by majority undersampling, each corresponding to one out of three possible classifications, were obtained from the Standford EchoNet-Dynamic repository.

Humoral immunity to SARS-CoV-2 in kidney transplant recipients and dialysis patients: IgA and IgG patterns unraveled after SARS-CoV-2 infection and vaccination.

Background: Infection with SARS-CoV-2 in high-risk groups such as kidney transplant and dialysis patients is shown to be associated with a more serious course of the disease. Four years after the start of the COVID-19 pandemic, crucial knowledge on the immune responses in these patient groups is still lacking. Therefore, this study aimed at investigating the humoral immune response after a SARS-CoV-2 infection compared to vaccination as well as the evolution of immunoglobulins over time.

Phenotyping chronic respiratory diseases with airways obstruction.

Given the high prevalence of asthma-chronic obstructive pulmonary disease overlap (ACO) in Vietnam, there is an urgent need to establish a simplified strategy for categorising patients as either having asthma or chronic obstructive pulmonary disease (COPD). This classification would streamline the application of treatment recommendations outlined by the Global Initiative for Asthma (GINA) and the Global Initiative for Chronic Obstructive Lung Disease (GOLD).Patients with obstructive lung function were classified as having COPD, asthma, or ACO based on GINA/GOLD guidelines.

Central Vein Sign, Cortical Lesions, and Paramagnetic Rim Lesions for the Diagnostic and Prognostic Workup of Multiple Sclerosis.

Background And Objectives: The diagnosis of multiple sclerosis (MS) can be challenging in clinical practice because MS presentation can be atypical and mimicked by other diseases. We evaluated the diagnostic performance, alone or in combination, of the central vein sign (CVS), paramagnetic rim lesion (PRL), and cortical lesion (CL), as well as their association with clinical outcomes.

Methods: In this multicenter observational study, we first conducted a cross-sectional analysis of the CVS (proportion of CVS-positive lesions or simplified determination of CVS in 3/6 lesions-Select3*/Select6*), PRL, and CL in MS and non-MS cases on 3T-MRI brain images, including 3D T2-FLAIR, T2*-echo-planar imaging magnitude and phase, double inversion recovery, and magnetization prepared rapid gradient echo image sequences.

Emotional Distress, Cognitive Complaints, and Care Needs among Advanced Cancer Survivors Treated with Immune Checkpoint Blockade: A Mixed-Method Study.

Background: There is a need for a better understanding of survivorship-related issues in advanced cancer survivors treated with immune checkpoint blockade (ICB). The purpose of this study was to identify survivorship-related issues, with a focus on psychological distress, cognitive complaints, physical sequelae, impact on family dynamics, and care needs in unresectable, advanced cancer survivors treated with ICB.

Methods: Semi-structured interviews and patient-reported outcome measures (PROMs) were conducted in survivors followed up at the University Hospital Brussels.

Malignancy in Abdominal Wall Endometriosis: Is There a Way to Avoid It? A Systematic Review.

Malignant-associated abdominal wall endometriosis (AWE) is a rare pathology, likely to occur in 1% of scar endometriosis. The objectives of this study were to update the evidence on tumor degeneration arising from AWE to notify about the clinical characteristics, the different treatments offered to patients and their outcomes. A comprehensive systematic review of the literature was conducted.

A retrospective comparison of mechanical cardio-pulmonary ventilation and manual bag valve ventilation in non-traumatic out-of-hospital cardiac arrests: A study from the Belgian cardiac arrest registry.

Background: The optimal ventilation modalities to manage out-of-hospital cardiac arrest (OHCA) remain debated. A specific pressure mode called cardio-pulmonary ventilation (CPV) may be used instead of manual bag ventilation (MBV). We sought to analyse the association between mechanical CPV and return of spontaneous circulation (ROSC) in non-traumatic OHCA.

Linking mitochondria metabolism, developmental timing, and human brain evolution.

Changes in developmental timing are an important factor of evolution in organ shape and function. This is particularly striking for human brain development, which, compared with other mammals, is considerably prolonged at the level of the cerebral cortex, resulting in brain neoteny. Here, we review recent findings that indicate that mitochondria and metabolism contribute to species differences in the tempo of cortical neuron development.

Use of the "Sepsis Risk Calculator" in Belgian Newborns: A Retrospective Cohort Study.

Background: Prevention of early-onset neonatal sepsis (EONS) is a frequent reason why many newborns receive unnecessary antibiotics. The Sepsis Risk Calculator (SRC) was developed by the Kaiser Permanente Institute as a multivariate risk assessment of EONS, aiming to reduce laboratory testing and empiric neonatal antibiotic therapy. Our objective was to assess the potential of the SRC in reducing antibiotic use in our setting.

Postresuscitation oxygen reserve index-guided oxygen titration in out-of-hospital cardiac arrest survivors: A randomised controlled trial.

Background And Purpose: Hyperoxia after return of spontaneous circulation is potentially harmful, and oxygen titration in a prehospital setting is challenging. This study aimed to compare outcomes of oxygen reserve index-supported prehospital oxygen titration during prehospital transport with those of standard oxygen titration.

Methods And Trial Design: We enrolled patients who experienced return of spontaneous circulation after cardiac arrest in a prospective randomized study.
