Bacterial contamination of mobile handwashing stations in hospital settings in the Democratic Republic of the Congo.

Background: As part of the containment of the COVID-19 pandemic, mobile handwashing stations (mHWS) were deployed in healthcare facilities in low-resource settings. We assessed mHWS in hospitals in the Democratic Republic of the Congo for contamination with Gram-negative bacteria.

Methods: Water and soap samples of in-use mHWS in hospitals in Kinshasa and Lubumbashi were quantitatively cultured for Gram-negative bacteria which were tested for antibiotic susceptibility.

Effect of Organic Anion Transporting Polypeptide 1B1 on Plasma Concentration Dynamics of Clozapine in Patients with Treatment-Resistant Schizophrenia.

The involvement of drug-metabolizing enzymes and transporters in plasma clozapine (CLZ) dynamics has not been well examined in Japanese patients with treatment-resistant schizophrenia (TRS). Therefore, this clinical study investigated the relationship between single nucleotide polymorphisms (SNPs) of various pharmacokinetic factors (drug-metabolizing enzymes and transporters) and dynamic changes in CLZ. Additionally, we aimed to determine whether CLZ acts as a substrate for pharmacokinetic factors using in vitro assays and molecular docking calculations.

Isomaltodextrin inhibits kidney enlargement induced by a high-protein diet through its metabolism by gut microbiota.

To evaluate the effects of the soluble fiber isomaltodextrin in a protein-biased diet, a 21-day protein diet trial was conducted in rats, with 60% of the calories derived from protein. The results revealed that the high-protein diet alone led to a significant increase in kidney weight. In contrast, the consumption of water with 5% isomaltodextrin dissolved in it, along with a high-protein diet, suppressed this weight gain.

Prescription Practices and Usage of Antimicrobials in a Tertiary Teaching Hospital in Rwanda: A Call for Antimicrobial Stewardship.

Antimicrobial resistance (AMR) is a global problem that results in high morbidity and mortality, particularly in low- and middle-income countries. Inappropriate use of antimicrobials is a major driver of AMR. This study aimed to evaluate the rate and quality of antimicrobial prescription and use at the University Teaching Hospital of Kigali (CHUK), a tertiary-referral teaching hospital.

Multiomics approaches disclose very-early molecular and cellular switches during insect-venom allergen-specific immunotherapy: an observational study.

Allergen-specific immunotherapy (AIT) induces immune tolerance, showing the highest success rate (>95%) for insect venom while a much lower chance for pollen allergy. However, the molecular switches leading to successful durable tolerance restoration remain elusive. The primary outcome of this observational study is the comprehensive immunological cellular characterization during the AIT initiation phase, whereas the secondary outcomes are the serological and Th2-cell-type-specific transcriptomic analyses.

Fungal infections (FIs) are spreading globally, raising a significant public health concern. However, its documentation remains sparse in Africa, particularly in Rwanda. This report provides a comprehensive review of FIs in Rwanda based on a systematic review of reports published between 1972 and 2022.

Marine fungal community composition and diversity across a polluted site in the south Mediterranean coast: the Monastir Bay, Tunisia.

Marine fungi communities play a crucial role in the recycling of nutrients, restoration of biological systems, and the overall functioning of ecosystems. While aquatic fungal communities do react to pollution, there is a significant lack of information regarding the changes in the fungal community's structure, caused by marine pollution. In this study, we aim to address this gap in knowledge by investigating the range and makeup of fungal species present in marine environments in a polluted bay in Tunisia, spanning a biodiversity hotspot (Monastir Bay).

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.

Regenerative anemia identification in cats: Red blood cell indices or morphology, what to use?

Background And Aim: Anemia, a clinical condition characterized by reduced erythrocytes, is often observed in cats. Regeneration indicates that the bone marrow can respond appropriately to anemia. The absolute reticulocyte count is the reference for differentiating regenerative and non-regenerative anemia, while red blood cell (RBC) indices and morphology provide supplementary information.

Flow cytometry assay modifications: Recommendations for method validation based on CLSI H62 guidelines.

The Clinical and Laboratory Standards Institute (CLSI) H62-Validation of Assays Performed by Flow Cytometry guideline, released in 2021, provides recommendations for platform workflow and quality system essentials, instrument setup and standardization, assay development and optimization and fit-for-purpose analytical method validation. In addition, CLSI H62 includes some recommendations for the validation strategies after a validated flow cytometric method has been modified. This manuscript builds on those recommendations and discusses the impact of different types of assay modifications on assay performance.

A first case of bacteremia and meningitis in a 5-week old child.

, previously known as , was initially isolated from powdered infant milk in 2010. It falls within the family (class: Enterobacterales). While was traditionally regarded as non-pathogenic, we now present a case of bacteraemia and meningitis in a 5-week-old child, successfully treated with cefotaxime.

Plasma myo-inositol elevation in heart failure: clinical implications and prognostic significance. Results from the BElgian and CAnadian MEtabolomics in HFpEF (BECAME-HF) research project.

Background: The metabolic environment plays a crucial role in the development of heart failure (HF). Our prior research demonstrated that myo-inositol, a metabolite transported by the sodium-myo-inositol co-transporter 1 (SMIT-1), can induce oxidative stress and may be detrimental to heart function. However, plasmatic myo-inositol concentration has not been comprehensively assessed in large cohorts of patients with heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF).

Prolonged Responses in Central Nervous System Relapsed Diffuse Large B-Cell Lymphoma After Chimeric Antigen Receptor T-Cell Therapy Using Targeted Treatments.

The introduction of chimeric antigen receptor T-cell (CAR-T cell) therapy has changed the treatment landscape of diffuse large B-cell lymphoma (DLBCL). However, the optimal treatment strategy after relapse after this therapy still needs to be elucidated. In this report, we describe the case of a 67-year-old male who relapsed after treatment with tisagenlecleucel as a third-line therapy.

Multi-omic profiling of pathogen-stimulated primary immune cells.

We performed long-read transcriptome and proteome profiling of pathogen-stimulated peripheral blood mononuclear cells (PBMCs) from healthy donors to discover new transcript and protein isoforms expressed during immune responses to diverse pathogens. Long-read transcriptome profiling reveals novel sequences and isoform switching induced upon pathogen stimulation, including transcripts that are difficult to detect using traditional short-read sequencing. Widespread loss of intron retention occurs as a common result of all pathogen stimulations.

Sporadic inclusion body myositis-derived myotube culture revealed muscle cell-autonomous expression profiles.

Sporadic inclusion body myositis (sIBM) is a muscle disease in older people and is characterized by inflammatory cell invasion into intact muscle fibers and rimmed vacuoles. The pathomechanism of sIBM is not fully elucidated yet, and controversy exists as to whether sIBM is a primary autoimmune disease or a degenerative muscle disease with secondary inflammation. Previously, we established a method of collecting CD56-positive myoblasts from human skeletal muscle biopsy samples.

Visualization of intracellular ATP dynamics in different nephron segments under pathophysiological conditions using the kidney slice culture system.

ATP depletion plays a central role in the pathogenesis of kidney diseases. Recently, we reported spatiotemporal intracellular ATP dynamics during ischemia reperfusion (IR) using GO-ATeam2 mice systemically expressing an ATP biosensor. However, observation from the kidney surface did not allow visualization of deeper nephrons or accurate evaluation of ATP synthesis pathways.
