The importance of microbiology reference laboratories and adequate funding for infectious disease surveillance.

Microbiology reference laboratories perform a crucial role within public health systems. This role was especially evident during the COVID-19 pandemic. In this Viewpoint, we emphasise the importance of microbiology reference laboratories and highlight the types of digital data and expertise they provide, which benefit national and international public health.

Regulatory preparedness for multicomponent nanomaterials: Current state, gaps and challenges of REACH.

In 2018 the European Commission adopted revisions to the Annexes of Regulation (EC) No 1907/2006 concerning registration, evaluation, authorisation and restriction of chemicals (REACH) to introduce nanomaterial-specific clarifications and provisions. Multicomponent nanomaterial (MCNM) is a non-regulatory term that has been used in recent EU-funded projects to describe nanomaterials with a complex structure and/or composition and which are expected to be increasingly used in products in the near future. This paper examines the regulatory preparedness of REACH, and its revised Annexes, for MCNMs.

Immune responses to SARS-CoV-2 in sub-Saharan Africa and western Europe: a retrospective, population-based, cross-sectional study.

Background: SARS-CoV-2 has been associated with a higher proportion of asymptomatic infections and lower mortality in sub-Saharan Africa than high-income countries. However, there is currently a lack of data on cellular immune responses to SARS-CoV-2 in people living in Africa compared with people in high-income regions of the world. We aimed to assess geographical variation in peripheral and mucosal immune responses.

Unmasking the chameleons: A benchmark for out-of-distribution detection in medical tabular data.

Background: Machine Learning (ML) models often struggle to generalize effectively to data that deviates from the training distribution. This raises significant concerns about the reliability of real-world healthcare systems encountering such inputs known as out-of-distribution (OOD) data. These concerns can be addressed by real-time detection of OOD inputs.

Supporting the continuous development and use of a patient partnership framework in European rare disease networks (ERNs): a scoping review of frameworks in the scientific literature.

The European Reference Networks (ERNs) for rare and complex diseases offer significant potential for building, maintaining and evaluating patient partnership, for which the recently developed ERN Patient Partnership Framework may serve as guidance. This scoping review aims to identify and describe relevant frameworks published in scientific literature, capturing key learning points to inform future updates of the ERN Patient Partnership Framework and promote its use in practice. MEDLINE, Embase, and the Web of Science Core Collection were searched to identify recently published frameworks (2013-2023) focused on patient partnership and aligned with at least one core ERN activity.

International Multicenter Cohort Study on Beta-Blocker-Free Treatment Strategies for Catecholaminergic Polymorphic Ventricular Tachycardia Patients.

Background: Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare, potentially life-threatening genetic heart disease. Nonselective beta-blockers (BBs) are highly effective in reducing CPVT-triggered arrhythmic events. However, some patients suffer from unacceptable BB side effects and might require strategies without a BB.

The challenge and promise of disentangling neurodevelopmental conditions a commentary on Davis et al. (2024).

This commentary evaluates the study by Davis et al. on the early behavioural manifestations of autism spectrum condition (ASC) and attention deficit hyperactivity disorder (ADHD) in preschool children. Davis et al.

B Cell Receptor Repertoire Analysis of the CD21 B Cell Compartment in Healthy Individuals, Patients With Sjögren's Disease, and Patients With Radiographic Axial Spondyloarthritis.

B cells with low or absent expression of CD21 (CD21 B cells) gained attention due to their expansion in the peripheral blood of patients with immune-mediated, rheumatic diseases. This is not only observed in typical autoimmune diseases like systemic lupus erythematosus and Sjögren's disease (SjD) but also in radiographic axial spondyloarthritis (r-axSpA), which is considered an autoinflammatory disease. To gain more insight into the origins of the heterogeneous CD21 B-cell population, and its relation to the plasmablast (PB) compartment, we profiled the B-cell-receptor (BCR) repertoire in CD27 and CD27 fractions of CD21 B cells and early PBs using next-generation sequencing.

Liver abscesses secondary to a non-O1/non-O139 Vibrio cholerae bacteremia acquired in a non-coastal area: a case report.

Non-O1/non-O139 Vibrio cholerae (NOVC) strains are a distinct group of Vibrio cholerae that do not cause epidemic cholera. NOVC infections usually cause mild forms of gastroenteritis, and rarely severe (extra)intestinal infections, mostly affecting immunocompromised patients. Here, we describe the clinical course of a patient with NOVC bacteremia causing multiple liver abscesses, after drinking from a freshwater well in a non-coastal area.

Clinical importance of patient-reported outcome measures in severe asthma: results from U-BIOPRED.

Rationale: Knowledge about the clinical importance of patient-reported outcome measures (PROMs) in severe asthma is limited.

Objectives: To assess whether and to what extent asthma exacerbations affect changes in PROMS over time and asthma-specific PROMs can predict exacerbations in adult patients with severe asthma in usual care.

Methods: Data of 421 patients with severe asthma (62% female; mean age 51.

The simple morphology of the sunfish heart.

The evolutionary conservation of the building plan of the heart suggests this organ is under substantial form-function constraints. Its form varies to such a degree, however, that it questions whether we understand the form-function relations of the heart. A previously published image of the heart of the sunfish (Mola mola, Tetraodontiformes) indicates the presence of an exceptionally simple topology of the chambers.

Short-term postoperative complications in preterm neonates with surgical necrotizing enterocolitis: a multicenter retrospective cohort study.

Background: Over half of preterm neonates with necrotizing enterocolitis (NEC) require surgery, making it essential to understand short-term postoperative outcomes and complication rates. Therefore, this study aimed to provide an overview of 30-day postoperative complications for NEC. Secondary, risk factors for minor and major short-term postoperative complications were identified.

Influence of the COVID-19 Pandemic on Influenza and SARS-CoV-2 Vaccination Willingness Among Dutch Nursing Home Health Care Workers.

Objectives: To explore the influenza and COVID-19 vaccination status among Dutch nursing home (NH) health care workers (HCWs), factors associated with vaccination including the influence of the pandemic, and the facilitators and barriers to vaccination willingness.

Design: An explanatory sequential mixed methods study.

Setting And Participants: HCWs providing direct care to residents in Dutch NHs.

Serotype distribution of remaining invasive pneumococcal disease after extensive use of ten-valent and 13-valent pneumococcal conjugate vaccines (the PSERENADE project): a global surveillance analysis.

Background: Widespread use of pneumococcal conjugate vaccines (PCVs) has reduced vaccine-type invasive pneumococcal disease (IPD). We describe the serotype distribution of IPD after extensive use of ten-valent PCV (PCV10; Synflorix, GSK) and 13-valent PCV (PCV13; Prevenar 13, Pfizer) globally.

Methods: IPD data were obtained from surveillance sites participating in the WHO-commissioned Pneumococcal Serotype Replacement and Distribution Estimation (PSERENADE) project that exclusively used PCV10 or PCV13 (hereafter PCV10 and PCV13 sites, respectively) in their national immunisation programmes and had primary series uptake of at least 70%.

Does providing atrial fibrillation patients, after pulmonary vein isolation, with a 1-lead ECG device relieve the emergency department?-A historically controlled prospective trial.

Unlabelled: Atrial fibrillation (AF) is a prevalent and clinically significant cardiac arrhythmia, with a growing incidence. The primary objectives in AF management are symptom relief, stroke risk reduction, and prevention of tachycardia-induced cardiomyopathy. Two key strategies for rhythm control include antiarrhythmic drug therapy and pulmonary vein isolation (PVI), with PVI being recommended for selected patients.

Progression of amplification during amoxicillin resistance development in .

Beta-lactam antibiotics are the most applied antimicrobials in human and veterinarian health care. Hence, beta-lactam resistance is a major health problem. Gene amplification of AmpC beta-lactamase is a main contributor to β-lactam resistance in .

Altered lipid profile and reduced neuronal support in human induced pluripotent stem cell-derived astrocytes from adrenoleukodystrophy patients.

X-linked adrenoleukodystrophy (ALD) is a peroxisomal disorder resulting from pathogenic variants in the ABCD1 gene that primarily affects the nervous system and is characterized by progressive axonal degeneration in the spinal cord and peripheral nerves and leukodystrophy. Dysfunction of peroxisomal very long-chain fatty acid (VLCFA) degradation has been implicated in ALD pathology, but the impact on astrocytes, which critically support neuronal function, remains poorly understood. Fibroblasts from four ALD patients were reprogrammed to generate human-induced pluripotent stem cells (hiPSC).

Clinical and laboratory risk factors for sickle cell retinopathy and maculopathy: a scoping review of the current evidence.

Sickle cell retinopathy (SCR) is a complication of sickle cell disease (SCD) and can drastically impair visual acuity. Screening for SCR is therefore recommended, but evidence for optimal screening frequency on an individual level is lacking. This scoping review mapped the current evidence on risk factors for SCR and sickle cell maculopathy (SCM).

High-Risk Embolic Sources on Cardiac Computed Tomography in Patients With Acute Ischemic Stroke: A Case-Control Study.

Background: Cardiac computed tomography (CT) is increasingly used to search for cardioembolic sources of acute ischemic stroke (AIS). We assessed the association between high-risk cardioembolic sources on cardiac CT and AIS.

Methods: We performed a case-control study using data from a prospective cohort including consecutive adult patients with suspected stroke who underwent cardiac CT acquired during the initial stroke imaging protocol between 2018 and 2020.

Noninvasive Mechanical Ventilation Is a Promising Way to Improve Lung Cancer Radiation Therapy.

Purpose: Accurate radiation therapy (RT) for lung cancer is challenging because of the respiratory motion of the tumor and surrounding organs at risk. Recently, non-invasive mechanical ventilation (NIMV) has been investigated as a novel respiratory motion management strategy. Using NIMV, respiratory motion can be minimized, while a larger lung volume yields less overall lung dose.

Efficient Multiplex Genome Editing of the Cyanobacterium Synechocystis sp. PCC6803 via CRISPR-Cas12a.

Cyanobacteria have been genetically modified to convert CO into biochemical products, but efficient genetic engineering tools, including CRISPR-Cas systems, remain limited. This is primarily due to the polyploid nature of cyanobacteria, which hinders their effectiveness. Here, we address the latter by specifically (i) modifying the RSF1010-based replicative plasmid to simplify cloning efforts while maintaining high conjugation efficiency; (ii) improving the design of the guide RNA (gRNA) to facilitate chromosomal cleavage; (iii) introducing template DNA fragments as pure plasmids via natural transformation; and (iv) using sacB to facilitate replicative plasmid curing.

Machine learning analysis of sex and menopausal differences in the gut microbiome in the HELIUS study.

Sex differences in the gut microbiome have been examined previously, but results are inconsistent, often due to small sample sizes. We investigated sex and menopausal differences in the gut microbiome in a large multi-ethnic population cohort study, including 5166 participants. Using machine learning models, we revealed modest associations between sex and menopausal status, and gut microbiota composition (AUC 0.
