[Balancing drug regulation and health democracy: The role of patient and healthcare professional advisors at the ANSM].

The French National Agency for Health Products (ANSM) is a regulatory and public health agency. Its regulatory, health policing and public health protection activities require a perfect fit with the field and the various people involved in the use of health products. Since 2019, the ANSM has adapted its organisation, procedures and processes to encourage and improve interaction with its stakeholders, as part of its policy of openness towards civil society.

An investigation of composition, morphology, mechanical properties, and microdamage accumulation of human type 2 diabetic bone.

This study investigates the biomechanics of type 2 diabetic bone fragility through a multiscale experimental strategy that considers structural, mechanical, and compositional components of ex vivo human trabecular and cortical bone. Human tissue samples were obtained from the femoral heads of patients undergoing total hip replacement. Mechanical testing was carried out on isolated trabecular cores using monotonic and cyclic compression loading and nanoindentation experiments, with bone microdamage analysed using micro-computed tomography (CT) imaging.

Effect of Phlebotomus papatasi on the fitness, infectivity and antimony-resistance phenotype of antimony-resistant Leishmania major Mon-25.

Leishmania major is responsible for zoonotic cutaneous leishmaniasis. Therapy is mainly based on the use of antimony-based drugs; however, treatment failures and illness relapses were reported. Although studies were developed to understand mechanisms of drug resistance, the interactions of resistant parasites with their reservoir hosts and vectors remain poorly understood.

Larval feeding activity and use of embryonic resources determine juvenile performance of the common prawn Palaemonserratus.

Phenotypic links are the potential for "carryover" of effects of experience during one life history stage into performance and selection at subsequent stages. They reflect plastic responses to the environment experienced during an early phase on the phenotype of subsequent phases. We are studying these effects by following individuals of the shrimp Palaemon serratus from the embryonic (eggs carried by females) through the larval phase (pelagic) to the juvenile phase (benthic).

Dysregulation of intercellular communication in vitro and in vivo via extracellular vesicles secreted by pancreatic duct adenocarcinoma cells and generated under the influence of the AG9 elastin peptide-conditioned microenvironment.

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy with poor prognosis due to its highly metastatic profile. Intercellular communication between cancer and stromal cells via extracellular vesicles (EVs) is crucial for the premetastatic microenvironment preparation leading to tumour metastasis. This study shows that under the influence of bioactive peptides derived from the extracellular matrix microenvironment, illustrated here by the AG-9 elastin-derived peptide (EDP), PDAC cells secrete more tumour-derived EVs.

Protein-based layer-by-layer films for biomedical applications.

The surface engineering of biomaterials is crucial for their successful (bio)integration by the body, the colonization by the tissue-specific cell, and the prevention of fibrosis and/or bacterial colonization. Performed at room temperature in an aqueous medium, the layer-by-layer (LbL) coating method is based on the alternating deposition of macromolecules. Versatile and simple, this method allows the functionalization of surfaces with proteins, which play a crucial role in several biological mechanisms.

Cytotoxic Effects of Doxorubicin on Cancer Cells and Macrophages Depend Differently on the Microcarrier Structure.

Microparticles are versatile carriers for controlled drug delivery in personalized, targeted therapy of various diseases, including cancer. The tumor microenvironment contains different infiltrating cells, including immune cells, which can affect the efficacy of antitumor drugs. Here, prototype microparticle-based systems for the delivery of the antitumor drug doxorubicin (DOX) were developed, and their cytotoxic effects on human epidermoid carcinoma cells and macrophages derived from human leukemia monocytic cells were compared in vitro.

Study protocol on the efficacy of exergames-acceptance and commitment therapy program for the treatment of major depressive disorder: comparison with acceptance and commitment therapy alone and treatment-as-usual in a multicentre randomised controlled trial.

Background: The prevalence of major depressive disorder (MDD) is on the rise globally, and the use of antidepressant medications for its treatment does not usually result in full remission. However, the combination of physical exercise and psychotherapy for the treatment of MDD increase the rate of full remission among patients. This three-armed, parallel-group, double-blinded randomised controlled trial (RCT) aims to assess and compare the effects between the combination of exergame and acceptance and commitment therapy (e-ACT) programme, ACT only and treatment-as-usual (TAU) control groups on the severity of depression and anxiety symptoms, the degree of experiential avoidance and quality of life (QoL) and the serum levels of depression biomarkers (such as brain-derived neurotrophic factor, C-reactive protein and vascular endothelial growth factor) among patients with MDD across three time points.

PIT-EASY survey: validation of the European Pituitary Pathology Group proposal for reporting pituitary neuroendocrine tumors.

The aim of this multicenter prospective survey called PIT-EASY was to assess the relevance of the European Pituitary Pathology Group (EPPG) diagnostic tools for pituitary neuroendocrine tumors (PitNETs) to improve the quality of their histological diagnosis. Each center performed at least 30 histological cases of PitNETs using the EPPG tools and assessed their value using a scorecard with 10 questions. For each center, the histological cases were carried out by pathologists with varying levels of expertise in pituitary pathology defined as junior, intermediate, and expert.

Cost-effectiveness of endovascular thrombectomy for acute ischemic stroke with established large infarct in Germany: a decision tree and Markov model.

Background: Recent studies, including the TENSION trial, support the use of endovascular thrombectomy (EVT) in acute ischemic stroke with large infarct (Alberta Stroke Program Early Computed Tomography Score (ASPECTS) 3-5).

Objective: To evaluate the cost-effectiveness of EVT compared with best medical care (BMC) alone in this population from a German healthcare payer perspective.

Methods: A short-term decision tree and a long-term Markov model (lifetime horizon) were used to compare healthcare costs and quality-adjusted life years (QALYs) between EVT and BMC.

SAnDReS 2.0: Development of machine-learning models to explore the scoring function space.

Classical scoring functions may exhibit low accuracy in determining ligand binding affinity for proteins. The availability of both protein-ligand structures and affinity data make it possible to develop machine-learning models focused on specific protein systems with superior predictive performance. Here, we report a new methodology named SAnDReS that combines AutoDock Vina 1.

We report the case of a 61-year-old male who had complications with a mitral valve (MV) bioprosthesis replacement by post-cardiotomy shock leading to VA ECMO implantation. The patient suffered early bioprosthetic valve failure owing to early thrombosis. The complication was successfully treated with a MV bioprosthesis transapical balloon valvuloplasty that restored normal leaflet mobility.

Post-operative osteopathic manipulative treatment of Morel-Lavallee syndrome assessed using infrared thermal imaging: A case report.

Introduction: The Morel-Lavallee lesion (MLL) is a closed, degloving soft-tissue injury, wherein the skin and subcutaneous tissue are separated from the underlying fascia. This syndrome causes disruption of wound healing. Infrared thermography is a noninvasive and pain-free tool that can be used to evaluate scar and the influence of osteopathic manipulative treatment.

Motor disorders related to oxaliplatin-induced peripheral neuropathy: long-term severity and impact on quality of life.

Purpose: Sensory chemotherapy-induced peripheral neuropathy (CIPN) is well-recognized, but motor CIPN remains understudied. This secondary analysis focused on the long-term severity and impact of motor disorders, their relation to sensory CIPN, neuropathic pain, psychological distress, and health-related quality of life (HRQoL) after oxaliplatin-based chemotherapy in colorectal cancer (CRC) survivors.

Methods: Data from a multicenter, cross-sectional study were re-analyzed to explore motor CIPN among CRC survivors up to 5 years post-chemotherapy, with no longitudinal follow-up.

Phytochemical study, antioxidant and tyrosinase inhibitory activities of Maire.

Chemical investigation of the aerial parts of Maire led to the isolation and identification of one sesquiterpene lactone glucoside of the guaianolide type (dihydropseudoivalin-4---d-glucopyranoside), along with nine known compounds including one diterpenoid, two sesquiterpenoids, three lignanes and three flavonoids. Their structures were established on the basis of spectroscopic analysis. All these compounds were evaluated for their DPPH radical scavenging and tyrosinase inhibitory activities.

Functionalized Calcium Carbonate-Based Microparticles as a Versatile Tool for Targeted Drug Delivery and Cancer Treatment.

Nano- and microparticles are increasingly widely used in biomedical research and applications, particularly as specific labels and targeted delivery vehicles. Silica has long been considered the best material for such vehicles, but it has some disadvantages limiting its potential, such as the proneness of silica-based carriers to spontaneous drug release. Calcium carbonate (CaCO) is an emerging alternative, being an easily available, cost-effective, and biocompatible material with high porosity and surface reactivity, which makes it an attractive choice for targeted drug delivery.
