Peripheral Nerve Stimulation Implantation Combining Ultrasound With Microendoscopy for Management of Chronic Neuropathic Pain: A Case Series Study.

Background: Peripheral nerve stimulation (PNS) has emerged as a minimally invasive percutaneous procedure addressing neuropathic pain. However, the percutaneous cylindrical lead ultrasound-guided implantation procedure requires expertise that limits widespread PNS utilization. To overcome these challenges, a microinvasive endoscopy device has very recently been developed, enhancing the precision of PNS implantation by providing accurate visualization of the targeted nerve.

Comparative analysis of the duodenojejunal microbiome with the oral and fecal microbiomes reveals its stronger association with obesity and nutrition.

The intestinal microbiota is increasingly recognized as a crucial player in the development and maintenance of various chronic conditions, including obesity and associated metabolic diseases. While most research focuses on the fecal microbiota due to its easier accessibility, the small intestine, as a major site for nutrient sensing and absorption, warrants further investigation to determine its microbiota composition and functions. Here, we conducted a clinical research project in 30 age- and sex-matched participants with ( = 15) and without ( = 15) obesity.

Plasminogen Activator Inhibitor-1 in the Pathophysiology of Late Life Depression.

Introduction: Late life depression (LLD) is characterized by specific clinical features including a high frequency of vascular form and frequent antidepressant treatment resistance. The expression and functions of the serine protease inhibitor, Plasminogen Activator Inhibitor-1 (PAI-1) is known to be altered by aging, vascular damage, insulin levels associated with a sedentary lifestyle, chronic stress leading to hypercortisolemia, and inflammatory changes linked to stress responses. These phenomena would be implicated in LLD like vascular depression.

GLS2 links glutamine metabolism and atherosclerosis by remodeling artery walls.

Metabolic dysregulation, including perturbed glutamine-glutamate homeostasis, is common among patients with cardiovascular diseases, but the underlying mechanisms remain largely unknown. Using the human MESA cohort, here we show that plasma glutamine-glutamate ratio is an independent risk factor for carotid plaque progression. Mice deficient in glutaminase-2 (Gls2), the enzyme that mediates hepatic glutaminolysis, developed accelerated atherosclerosis and susceptibility to catastrophic cardiac events, while Gls2 overexpression partially protected from disease progression.

Defective germinal center selection results in persistence of self-reactive B cells from the primary to the secondary repertoire in Primary Antiphospholipid Syndrome.

Primary antiphospholipid syndrome (PAPS) is a life-threatening clotting disorder mediated by pathogenic autoantibodies. Here we dissect the origin of self-reactive B cells in human PAPS using peripheral blood and bone marrow of patients with triple-positive PAPS via combined single-cell RNA sequencing, B cell receptors (BCR) repertoire profiling, CITEseq analysis and single cell immortalization. We find that antiphospholipid (aPL)-specific B cells are present in the naive compartment, polyreactive, and derived from the natural repertoire.

Relationships between cognition, functioning, and quality of life of euthymic patients with bipolar disorder: Structural equation modeling with the FACE-BD cohort.

Background: Quality of life is decreased in bipolar disorders (BD) and contributes to poor prognosis. However, little is known about the causal pathways that may affect it. This study aimed to explore health-related QoL (HRQoL) in BD and investigate its relationship with cognition and psychosocial functioning.

Machine learning for precision diagnostics of autoimmunity.

Early and accurate diagnosis is crucial to prevent disease development and define therapeutic strategies. Due to predominantly unspecific symptoms, diagnosis of autoimmune diseases (AID) is notoriously challenging. Clinical decision support systems (CDSS) are a promising method with the potential to enhance and expedite precise diagnostics by physicians.

Epidermal maintenance of Langerhans cells relies on autophagy-regulated lipid metabolism.

Macroautophagy (often-named autophagy), a catabolic process involving autophagy-related (Atg) genes, prevents the accumulation of harmful cytoplasmic components and mobilizes energy reserves in long-lived and self-renewing cells. Autophagy deficiency affects antigen presentation in conventional dendritic cells (DCs) without impacting their survival. However, previous studies did not address epidermal Langerhans cells (LCs).

Melatonin alleviates heat stress-induced spermatogenesis dysfunction in male dairy goats by regulating arachidonic acid metabolism mediated by remodeling the gut microbiota.

Background: Heat stress (HS) commonly occurring in summer has gradually become a factor threatening the reproductive performance of male dairy goats by reducing their fecundity. Despite the melatonin is applied to relieve HS, it is still unclear whether melatonin protects against reproductive damage induced by HS in dairy goats and how it works. The purpose of the present study is to evaluate the role of melatonin in alleviating HS-induced spermatogenesis dysfunction in male dairy goats and further explore its mechanism.

[Over-the-counter non-steroidal anti-inflammatory medications: Focus on the management of acute pain].

Non-steroidal anti-inflammatory drugs (NSAIDs) are the second most widely used class of analgesics in France, after paracetamol. Some NSAIDs are available over the counter (OTC), without a prescription, on the advice of a pharmacist. NSAIDs have recently been the subject of safety alerts from France's Agence nationale de sécurité du médicament et des produits de santé (ANSM), highlighting a risk of worsening certain bacterial infections.

Role of purinoreceptors in the release of extracellular vesicles and consequences on immune response and cancer progression.

Cell-to-cell communication is a major process for accommodating cell functioning to changes in the environments and to preserve tissue and organism homeostasis. It is achieved by different mechanisms characterized by the origin of the message, the molecular nature of the messenger, its speed of action and its reach. Purinergic signalling is a powerful mechanism initiated by extracellular nucleotides, such as ATP, acting on plasma membrane purinoreceptors.

The cGAS-STING pathway in HIV-1 and Mycobacterium tuberculosis coinfection.

Mycobacterium tuberculosis (M. tuberculosis) infection is the most common opportunistic infection in human immunodeficiency virus-1 (HIV-1)-infected individuals, and the mutual reinforcement of these two pathogens may accelerate disease progression and lead to rapid mortality. Therefore, HIV-1/M.

[Evaluate the host cellular immune response to better prevent and diagnose viral infections].

In medicine, virological diagnosis is mainly based on the detection of the viral genome and antigens, or on the identification of specific antibodies produced in response to infection. These strategies are suitable for characterizing an active infection or past contact with an already known virus. The recent development of tests for evaluating the host's cellular immune response opens new perspectives for personalized patient care based on immunomonitoring.

Cryo-EM reveals structural basis for human AIM/CD5L recognition of polymeric immunoglobulin M.

Cell surface scavenger receptors contribute to homoeostasis and the response to pathogens and products associated with damage by binding to common molecular features on a wide range of targets. Apoptosis inhibitor of macrophage (AIM/CD5L) is a soluble protein belonging to the scavenger receptor cysteine-rich (SRCR) superfamily that contributes to prevention of a wide range of diseases associated with infection, inflammation, and cancer. AIM forms complexes with IgM pentamers which helps maintain high-levels of circulating AIM in serum for subsequent activation on release from the complex.

Long term follow-up of the STOPAGO study.

An open prospective, multicenter study enrolled 48 selected patients with chronic immune thrombocytopenia who achieved complete response for 1 year on thrombopoietin receptor agonists, half of the patients maintained a sustained response off treatment 4 years after treatment discontinuation. NCT03119974.
