A scoping review evaluating the current state of gut microbiota and its metabolites in valvular heart disease physiopathology.

Background: The human microbiome is crucial in regulating intestinal and systemic functions. While its role in cardiovascular disease is better understood, the link between intestinal microbiota and valvular heart diseases (VHD) remains largely unexplored.

Methods: Peer-reviewed studies on human, animal or cell models analysing gut microbiota profiles published up to April 2024 were included.

The Hunt for Kinder Practices: Minimising Harm to Wild Boar Welfare, Insights from a Qualitative Study in Wallonia (Belgium).

As in the rest of Europe, the Belgian boar population has been tending to increase, posing new challenges to management by hunting. Moreover, in autumn 2018, the African Swine Fever (ASF) virus penetrated Belgian territory. In response to this so-called overpopulation and to this health crisis, wild boars were massively culled by hunters and other nature managers.

Metabolomic profile of cerebral tissue after acoustically-mediated blood-brain barrier opening in a healthy rat model: a focus on the contralateral side.

Microbubble (MB)-assisted ultrasound (US) is an innovative modality for the non-invasive, targeted, and efficient delivery of therapeutic molecules into the brain. Previously, we reported the first metabolomic signature of blood-brain barrier opening (BBBO) induced by MB-assisted US. In the present study, the neurometabolic consequences of acoustically-mediated BBBO on cerebral tissue were investigated using multimodal metabolomics approaches.

Gut metabolomic and microbiota analyses in ALS mice reveal specific metabolites despite the absence of significant gut dysbiosis.

Objective: Over the past years, interest in the role of gut microbiota in neurodegenerative diseases has emerged. Despite numerous publications over the past decade, both in human and pre-clinical studies, there is no clear consensus on the microbiota's role or involvement in ALS. Few studies on mouse models of ALS highlighted a correlation between specific bacteria species and the prognostic or severity of the disease.

Metabolomics of basal tears in amyotrophic lateral sclerosis: A cross-sectional study.

Purpose: Amyotrophic lateral sclerosis (ALS) clinical variability, along with the lack of conclusive diagnostic instruments, result in average diagnosis delays of 9 months. This study aimed to assess whether metabolomic profiling of basal tears in ALS patients could act as a biological marker for diagnosing ALS, predicting prognosis, and discriminating between endophenotypes.

Methods: A single-center prospective case-control study was conducted in France from September 2021 to March 2023 including patients with ALS according to the revised EI Escorial criteria.
