Acute Nonsustained Mitral Isthmus Block Obtained With Sphere-9 Lattice-Tip Catheter Completed With Vein of Marshall Ethanol Infusion.

J Cardiovasc Electrophysiol

January 2025

Hôpital Cardiologique du Haut Léveque, CHU de Bordeaux, L'Institut de RYthmologie et modelisation Cardiaque (LIRYC), Université de Bordeaux, Bordeaux, France.

Background: Achieving a durable mitral line block using radiofrequency as a part of an anatomical approach for ablation in patients with persistent atrial fibrillation or for treating peri-mitral flutter has always been challenging due to the complex anatomy of the mitral isthmus. Epicardial ablation via the coronary sinus and the vein of Marshall has been proposed to help create durable lesions. Recently, a novel lattice-tip catheter using pulsed field ablation has shown promising results for creating mitral lines, despite limited data.

Background And Aims: Alcohol Use Disorder (AUD) is a psychiatric disorder characterized notably by gut microbial dysbiosis and insufficient dietary fiber intake. This study aims to investigate the effect of dietary fiber placebo-controlled intervention in patients suffering from AUD during a three-week period of alcohol withdrawal, in order to discover microbial-derived metabolites that could be involved in metabolic and behavioral status.

Methods: A randomized, double-blind, placebo-controlled study was performed with 50 AUD patients supplemented with inulin (prebiotic dietary fiber) or maltodextrin (placebo) during 17 days.

A Manufacturing Technique for Binary Clathrate Hydrates for Cold and Very Cold Neutron Production.

Materials (Basel)

January 2025

Institut Laue-Langevin (ILL), 71 Avenue des Martyrs, 38042 Grenoble Cedex 9, France.

Intense sources of very cold neutrons (VCNs) would be beneficial for various neutron scattering techniques and low-energy particle physics experiments. Binary clathrate hydrates hosting deuterated tetrahydrofuran (THF-d) and dioxygen show promise as potential moderators for such sources due to a rich spectrum of localized low-energy excitations of the encaged guest molecules. In this article, we present a reliable manufacturing technique for such hydrates.

Purpose: Establishing an accurate prognosis remains challenging in older patients with cancer because of the population's heterogeneity and the current predictive models' reduced ability to capture the complex interactions between oncologic and geriatric predictors. We aim to develop and externally validate a new predictive score (the Geriatric Cancer Scoring System [GCSS]) to refine individualized prognosis for older patients with cancer during the first year after a geriatric assessment (GA).

Materials And Methods: Data were collected from two French prospective multicenter cohorts of patients with cancer 70 years and older, referred for GA: ELCAPA (training set January 2007-March 2016) and ONCODAGE (validation set August 2008-March 2010).

SCAPs (Stem Cells from Apical Papilla), derived from the apex of forming wisdom teeth, extracted from teenagers for orthodontic reasons, belong to the MSCs (Mesenchymal Stromal Cells) family. They have multipotent differentiation capabilities and are a potentially powerful model for investigating strategies of clinical cell therapies. Since autophagy-a regulated self-eating process-was proposed to be essential in osteogenesis, we investigated its involvement in the SCAP model.

Background And Aim: Human dental pulp stem cells (hDPSCs) constitute a promising alternative for central nervous system (CNS) cell therapy. Unlike other human stem cells, hDPSCs can be differentiated, without genetic modification, to neural cells that secrete neuroprotective factors. However, a better understanding of their real capacity to give rise to functional neurons and integrate into synaptic networks is still needed.

Introduction: Myeloid cells trafficking from the periphery to the central nervous system are key players in multiple sclerosis (MS) through antigen presentation, cytokine secretion and repair processes.

Methods: Combination of mass cytometry on blood cells from 60 MS patients at diagnosis and 29 healthy controls, along with single cell RNA sequencing on paired blood and cerebrospinal fluid (CSF) samples from 5 MS patients were used for myeloid cells detailing.

Results: Myeloid compartment study demonstrated an enrichment of a peculiar classical monocyte population in 22% of MS patients at the time of diagnosis.

Background: Chronic obstructive pulmonary disease (COPD) is a common treatable disease often diagnosed in patients with risk factors after a prolonged period with suggestive symptoms. Our qualitative study aimed to identify barriers to establishing diagnosis in the natural history of this condition.

Methods: An inductive thematic analysis was performed on structured interviews with patients, general practitioners (GPs) and pulmonologists in France.

Ergothioneine (ET), a dietary thione/thiol, is receiving growing attention for its possible benefits in healthy aging and metabolic resilience. Our study investigates ET's effects on healthspan in aged animals, revealing lifespan extension and enhanced mobility in Caenorhabditis elegans, accompanied by improved stress resistance and reduced age-associated biomarkers. In aged rats, ET administration enhances exercise endurance, muscle mass, and vascularization, concomitant with higher NAD levels in muscle.

Producing oral soft tissues using tissue engineering could compensate for the disadvantages of autologous grafts (limited availability and increased patient morbidity) and currently available substitutes (shrinkage). However, there is a lack of in vitro-engineered oral tissues due to the difficulty of obtaining stable pre-vessels that connect to the host and enable graft success. The main objective was to assess the connection of pre-vascularised 3D-bioprinted gingival substitutes to the host vasculature when subcutaneously implanted in immunodeficient mice.

Penetration of antimicrobial treatments into the cerebrospinal fluid is essential to successfully treat infections of the central nervous system. This penetration is hindered by different barriers, including the blood-brain barrier, which is the most impermeable. However, inflammation may lead to structural alterations of these barriers, modifying their permeability.

The pathophysiology of residual sleepiness in treated obstructive sleep apnoea (OSA) remains poorly understood. Animal models suggest that it may involve neuronal damage due to intermittent hypoxia and sleep fragmentation. In a cohort of 122 continuous positive airway pressure (CPAP) treated OSA patients referred for maintenance of wakefulness test, we explored the determinants of (objective) alertness and those of (subjective) sleepiness assessed by Epworth Sleepiness Scale.

All-solid-state lithium batteries (ASSBs) are among the most promising energy storage technologies, particularly for electric vehicles, due to their enhanced safety. However, performances of these systems are still hindered by interfacial side reactions at electrode/electrolyte interfaces, especially when sulfide electrolytes are used, and additional issues of mechanical nature. In this work, an ASSB system composed of an argyrodite (LiPSCl) electrolyte, a lithium-rich sulfide cathode (LiTiS) operating at moderate voltage, and a lithium metal anode is investigated.

Background: Chronic Limb-Threatening Ischemia (CLTI) represents the most advanced stage of Peripheral Artery Disease (PAD) and is associated with dire prognosis, characterized by a substantial risk of limb amputation and diminished life expectancy. Despite significant advancements in therapeutic interventions, the underlying mechanisms precipitating the progression of PAD to CLTI remain elusive.

Methods: Considering diabetes is one of the main risk factors contributing to PAD exacerbation into CLTI, we compared hind limb ischemia recovery in HFD STZ vs.

The tumor microenvironment (TME) plays a critical role in cancer progression and therapeutic responsiveness, with the tumor immune microenvironment (TIME) being a key modulator. In head and neck squamous cell carcinomas (HNSCC), immune cell infiltration significantly influences the response to radiotherapy (RT). A better understanding of the TIME in HNSCC could help identify patients most likely to benefit from combining RT with immunotherapy.
