Étude coût-utilité de l’association de la metformine aux différentes classes d’antidiabétiques chez le sujet âgé de plus de 80 ans

2020

Resume Introduction La prevalence du diabete chez le sujet âge est superieure a 20 %. La prevention de l’hypoglycemie medicamenteuse est le point cle de la prise en charge therapeutique du diabete chez cette population de patients. A ce jour, il n’existe pas d’agent de choix a ajouter a la metformine en cas de diabete non controle chez le sujet âge de plus de 80 ans. Materiels et methodes Une revue de la litterature a ete menee afin d’etablir les types d’evenements hypoglycemiques et leur probabilite de survenue. Suite a une determination du cout des differents actes necessaires dans la prise en charge des evenements hypoglycemiques et des traitements associes, il a ete possible de calculer…

Conciliation des traitements médicamenteux à l’admission : expérimentation en établissement de santé mentale et éligibilité des patients pouvant en b…

2017

Resume Introduction La mise en place de la conciliation des traitements medicamenteux (CTM) a effectifs constants necessite d’etre efficiente en definissant notamment des criteres d’eligibilite des patients. Materiel et methodes Une etude monocentrique observationnelle a ete menee en etablissement de sante mentale a titre experimental. Elle a pour objectif d’identifier les criteres d’eligibilite a la conciliation pour la mener en priorite chez les patients les plus a risque d’iatrogenie medicamenteuse et de permettre l’implantation d’un processus de conciliation efficient. Des criteres generaux (6), somatiques (14) et psychiatriques (15) potentiellement pertinents ont ete identifies et etud…

Inteligencia artificial, big data y aplicaciones contra la COVID-19: privacidad y protección de datos

2020

espanolEl big data y la IA han fracasado en la prevencion, pero pueden ser muy utiles frente a la COVID-19 e incluso para evitar confinamientos y otras restricciones de derechos que provoca. La IA puede ser extremadamente eficaz para integrar, estructurar y extraer informacion y conocimiento de ingente cantidad y variedad de big data para la investigacion biomedica. Tambien es util para mejorar la atencion e informacion ciudadana y de salud, la telemedicina y la mejor asignacion de los recursos humanos y materiales. Mas amenazante para la privacidad puede ser el desarrollo de apps, pasaportes biologicos electronicos o sistemas de geolocalizacion, trazabilidad y monitoreo de personas impleme…

Évaluation des coûts médicamenteux évités grâce aux inclusions des patients atteints d’hémopathie maligne dans les essais cliniques

2020

Resume Introduction Les essais cliniques (EC) sont indispensables pour evaluer l’efficacite et l’innocuite de nouveaux traitements. Ils peuvent representer une mesure d’economie grâce a la fourniture des medicaments par le promoteur. Objectif L’objectif de cette etude est d’evaluer les couts evites en medicament hors-GHS ou sous Autorisation Temporaire d’Utilisation (ATU) par l’inclusion d’un patient dans un EC d’Hematologie. Materiels et methodes C’est une etude de cout, retrospective, monocentrique, observationnelle. La perspective de l’etude est elargie du point de vue de l’assurance maladie obligatoire. Nous avons inclus les EC d’Hematologie ayant eu au moins une dispensation entre 2007…

Betulinic Acid Exerts Cytotoxic Activity Against Multidrug-Resistant Tumor Cells via Targeting Autocrine Motility Factor Receptor (AMFR).

2018

Betulinic acid (BetA) is a naturally occurring pentacyclic triterpene isolated from the outer bark of white-barked birch trees and many other medicinal plants. Here, we studied betulinic acid's cytotoxic activity against drug-resistant tumor cell lines. P-glycoprotein (MDR1/ABCB1) and BCRP (ABCG2) are known ATP-binding cassette (ABC) drug transporters that mediating MDR. ABCB5 is a close relative to ABCB1, which also mediates MDR. Constitutive activation of the EGF receptor is tightly linked to the development of chemotherapeutic resistance. BetA inhibited P-gp, BCRP, ABCB5 and mutation activated EGFR overexpressing cells with similar efficacy as their drug-sensitive parental counterparts. …

Investigation of Isoindolo[2,1-a] quinoxaline-6-imines as Topoisomerase I Inhibitors with Molecular Modeling Methods

2017

Background: Isoindolo[2,1-alpha] quinoxalines constitute an important class of compounds which demonstrated potent antiproliferative activity against different human tumor cell lines and topoisomerase I inhibitors. In particular, their water soluble imine or iminium salts recently synthesized showed potent growth inhibitory effect on NCI-60 tumor cell line panel and biological studies performed on the most active compounds demonstrated that they cause DNA damage via topoisomerase I poisoning. Objective: Herein, we investigate with molecular modeling methods, the common features responsible for topoisomerase I inhibition of the water-soluble isoindolo[2,1-alpha] quinoxalin-6-imines, by compa…

Biofilm Inactivation using Photodynamic Therapy in Dentistry: a review of literature

2020

Introduction: Photodynamic therapy (PDT) is a therapy involving light and a photosensitising chemical substance, used in conjunction with molecular oxygen in order to elicit cell death (photo-toxicity) and thus ability to kill microbial cells, including bacteria, fungi and viruses. Photodynamic therapy is an alternative method of biofilm disruption and it is considered a new way of microorganism inactivation. It is also an additional procedure to reduce the infection rate in patients, caused by the increasing antimicrobials resistance of bacteria. The aim of this literature review was to evaluate the specific effects and the antibacterial effectiveness of photodynamic therapy using differen…

Biowaiver Monograph for Immediate-Release Solid Oral Dosage Forms: Amoxicillin Trihydrate

2018

Literature and experimental data relevant to waiver of in vivo bioequivalence (BE) testing for the approval of immediate-release solid oral dosage forms containing amoxicillin trihydrate are reviewed. Solubility and permeability characteristics according to the Biopharmaceutics Classification System (BCS), therapeutic uses, therapeutic index, excipient interactions, as well as dissolution and BE and bioavailability studies were taken into consideration. Solubility and permeability studies indicate that amoxicillin doses up to 875 mg belong to BCS class I, whereas 1000 mg belongs to BCS class II and doses of more than 1000 mg belong to BCS class IV. Considering all aspects, the biowaiver pro…

Anti-Acne Activity of Italian Medicinal Plants Used for Skin Infection

2016

Propionibacterium acnes is implicated in the pathogenesis of acne vulgaris, which impacts >85% of teenagers. Novel therapies are in high demand and an ethnopharmacological approach to discovering new plant sources of anti-acne therapeutics could contribute to filling this void in effective therapies. The aims of our study were two-fold: (1) To determine if species identified in ethnopharmacological field studies as having traditional uses for skin and soft tissue infection (SSTI) exhibit significantly more activity against P. acnes than species with no such reported use; and (2) Chemically characterize active extracts and assess their suitability for future investigation. Extracts of Ita…
