Compatibility of irinotecan-loaded DC Bead with different volumes and types of non-ionic contrast media.
2015
Objectives Irinotecan-loaded microspheres are used for simultaneous embolisation and chemotherapy of liver metastases of colorectal carcinoma. The aim of the study was to evaluate the compatibility of recently introduced DC Bead M1 (bead size 70–150 µm) loaded with irinotecan after admixture with different types and volumes of non-ionic contrast media over a maximum period of 24 h and storage at room temperature. Methods Test suspensions were prepared by loading 2 mL DC Bead M1 with 100 mg irinotecan within 2 h. The loading efficiency was determined by measuring the concentrations of irinotecan in the excess solutions via a reversed phase high pressure liquid chromatography (RP-HPLC) assay …
The Effects of Oregano Oil on Fungal Infections Associated with Metabolic Syndrome
2020
International audience; This study aims to compare the evolution of mycosis associated with metabolic syndrome under allopathic treatment compared to phytotherapy using oregano essential oil. The study was conducted over a period of 6 months, on a total of 72 patients diagnosed with fungal infections associated with metabolic syndrome. The patients were divided into 3 groups, depending on the administered treatment: group 1: 24 patients who received allopathic treatment; group 2: 24 patients who received oregano oil treatment; group 3: control, which did not undergo any antifungal treatment. All three groups were subjected to specific diet therapy for mycosis. The patients were initially ev…
Diagnosis and novel clinical treatment strategies for pyoderma gangrenosum
2019
Introduction: Pyoderma gangrenosum (PG) is a noninfectious, reactive inflammatory neutrophilic dermatosis that is commonly associated with autoimmune and neoplastic disorders. There are emerging diagnostic tools and treatment options for PG.Area covered: The diagnosis of PG should be seriously considered when managing ulcers to avoid unnecessary medical and surgical complications with prompt and suitable treatment. There are no standardized treatment guidelines for PG, and current therapy largely depends on the severity and progression of the disease. Systemic corticosteroids, immunosuppressant therapy, and biologic agents remain mainstay therapies. In this article, we present a literature …
Genotype-driven pharmacokinetic simulations of warfarin levels in Puerto Ricans.
2020
Abstract Objectives The inter-individual variability of warfarin dosing has been linked to genetic polymorphisms. This study was aimed at performing genotype-driven pharmacokinetic (PK) simulations to predict warfarin levels in Puerto Ricans. Methods Analysis of each individual dataset was performed by one-compartmental modeling using WinNonlin®v6.4. The k e of warfarin given a cytochrome P450 2C9 (CYP2C9) genotype ranged from 0.0189 to 0.0075 h−1. K a and V d parameters were taken from literature. Data from 128 subjects were divided into two groups (i.e., wild-types and carriers) and statistical analyses of PK parameters were performed by unpaired t-tests. Results In the carrier group (n=6…
Influence of spurious dilution and hyperglycemia on erythrocytes and platelets evaluated with two different hematological analyzers
2015
The integrity of whole blood samples may be compromised by suboptimal collection practices. Therefore, we investigated the influence of spurious hyperglycemia on erythrocytes and platelets, assessed with two hematological analyzers using optical or impedance technique. Three K2EDTA blood specimens were collected from 12 healthy subjects, pooled and divided into four aliquots. The first aliquot was left untreated (glucose concentration 4.4 mmol/L), whereas scalar amounts of standard 5% glucose solution were added to the remaining, generating glucose contamination of 5% (19.2 mmol/L), 10% (33 mmol/L) and 20% (62 mmol/L). Hematological testing was then performed using Siemens Advia 2120 and Sy…
Therapeutical approach to plasma homocysteine and cardiovascular risk reduction
2008
Marcello Ciaccio, Giulia Bivona, Chiara BelliaDepartment of Medical Biotechnologies and Forensic Medicine, Faculty of Medicine, University of Palermo, ItalyAbstract: Homocysteine is a sulfur-containing aminoacid produced during metabolism of methionine. Since 1969 the relationship between altered homocysteine metabolism and both coronary and peripheral atherotrombosis is known; in recent years experimental evidences have shown that elevated plasma levels of homocysteine are associated with an increased risk of atherosclerosis and cardiovascular ischemic events. Several mechanisms by which elevated homocysteine impairs vascular function have been proposed, including impairment of endothelial…
Impaired border zone formation and adverse remodeling after reperfused myocardial infarction in cannabinoid CB2 receptor deficient mice.
2014
Abstract Aims Reperfusion of myocardial infarction is associated with inflammatory reaction and subsequent myocardial remodeling with a rapid scar formation in mice. The cannabinoid receptor CB2 has been associated with cardioprotection and regulation of macrophage function. We investigated its role in remodeling of reperfused infarction. Main methods One hour LAD-occlusion was followed by reperfusion over 6 h and 1, 3 and 7 days in wild-type C57/BL6J (WT) and CB2 receptor-deficient (Cnr2 −/− ) mice (n = 8/group). Hearts were processed for functional, morphological and mRNA/protein analysis, and tissue concentration of endocannabinoids was determined using liquid chromatography-multiple rea…
PS-039 DokuPIK – Pharmaceutical interventions: Do ward pharmacists know how to document?
2014
Background The internet-based categorical, hierarchical documentation system for routine pharmaceutical interventions (PIs) DokuPIK is widely used especially among German ward-based pharmacists. Purpose To conduct a survey-based study on its clinical usability. Materials and methods Out of 498 registered DokuPIK users, 37 volunteered to independently evaluate 24 standardised case reports 1 between 01–03 2012. Case evaluation was restricted to the reason for PI and was performed based on 26 given survey items with no limit on the number of items chosen. Ratings were conducted electronically and anonymously. In order to define meaningful reference item selections, majority decisions made by 5…
Cigarette smoke extract activates human bronchial epithelial cells affecting non-neuronal cholinergic system signalling in vitro.
2010
Abstract Aims Acetylcholine (ACh) is synthesized by Choline Acetyl-Transferase (ChAT) that exerts its physiological effects in airway epithelial cells via muscarinic receptor (MR) activation. We evaluate the effect of ACh stimulation on human bronchial epithelial cells (16-HBE) and test whether cigarette smoke extract (CSE) can modify the basal cellular response to ACh affecting the non-neuronal cholinergic system signalling. Main methods ACh stimulated 16-HBE were tested for ACh-binding, Leukotriene B 4 (LTB 4 ) release and ERK1/2 and NFkB pathway activation. Additionally, we investigated all the aforementioned parameters as well as ChAT and MR proteins and mRNA expression and endogenous A…
Applicability of the STOPP/START criteria to older polypathological patients in a long-term care hospital
2017
Objectives To analyse the applicability of the STOPP/START criteria as a tool to identify patients with potentially inappropriate medications (PIM) during pharmaceutical validation of prescriptions in a long-term care hospital, to identify risk factors for PIM and to characterise the physiological systems and drugs more frequently associated with these PIM. Methods An interventional, prospective and longitudinal study was conducted in polypathological patients aged >65 years. Usual pharmaceutical care and the STOPP/START criteria were used to identify PIM and to plan pharmaceutical interventions at admission. At discharge, the discharge summaries were reviewed using the STOPP/START criteria…
