Prescription drug use during pregnancy in France: a study from the national health insurance permanent sample.
2017
International audience; PurposeTo provide an up-to-date account of drug prescription during pregnancy in France from 2011 to 2014 using the permanent sample of the French national computerized healthcare database and with a focus on recommended supplementations, fetotoxic drugs and teratogenic drugs.MethodsAll pregnancies identified by the International Classification of Diseases, 10th Revision codes list in the hospitalization database, lasting more than 9 weeks of amenorrhea and whose delivery occurred between 01/01/2011 and 12/31/2014, were included. Drugs delivered between the trimester before and until the end of the pregnancy were included. Drug exposure prevalence was calculated for …
New antitrichomonal drug-like chemicals selected by bond (edge)-based TOMOCOMD-CARDD descriptors.
2008
Bond-based quadratic indices, new TOMOCOMD-CARDD molecular descriptors, and linear discriminant analysis (LDA) were used to discover novel lead trichomonacidals. The obtained LDA-based quantitative structure-activity relationships (QSAR) models, using nonstochastic and stochastic indices, were able to classify correctly 87.91% (87.50%) and 89.01% (84.38%) of the chemicals in training (test) sets, respectively. They showed large Matthews correlation coefficients of 0.75 (0.71) and 0.78 (0.65) for the training (test) sets, correspondingly. Later, both models were applied to the virtual screening of 21 chemicals to find new lead antitrichomonal agents. Predictions agreed with experimental resu…
Multifactorial nature of hepatocellular carcinoma drug resistance: Could plant polyphenols be helpful?
2007
Primary hepatocellular carcinoma (HCC) is a quite frequent tumor which results in high mortality and most often exhibits a poor response to present drug therapies. Clearly, a thorough understanding of the biological bases of this malignancy might suggest new strategies for its treatment. Here we examine the evidences that both "pharmacological" mechanisms (e.g. drug transporter or detoxification enzyme over-expression) and alterations in other critical factors, including the IAPs (Inhibitory of Apoptosis Proteins), involved in enhancement of cell survival and proliferation may determine the therapeutic resistance of HCC; we also underline the possible role in the process of the activation o…
The In Silico Fischer Lock-and-Key Model: The Combined Use of Molecular Descriptors and Docking Poses for the Repurposing of Old Drugs
2019
Not always lead compound and/or derivatives are suitable for the specific biological target for which they are designed but, in some cases, discarded compounds proved to be good binders for other biological targets; therefore, drug repurposing constitute a valid alternative to avoid waste of human and financial resources. Our virtual lock-and-key methods, VLKA and Conf-VLKA, furnish a strong support to predict the efficacy of a designed drug a priori its biological evaluation, or the correct biological target for a set of the selected compounds, allowing thus the repurposing of known and unknown, active and inactive compounds.
Protection of Azidothymidine-Induced Cardiopathology in Mice by Mildronate, a Mitochondria-Targeted Drug
2006
Azidothymidine, a nucleoside-analogue reverse transcriptase inhibitor (NRTI), is a commonly used antiretroviral drug in AIDS treatment, however its use is limited by severe toxic side effects due to its influence on mitochondria that result in myopathy, particularly affecting the cardiac muscle. We suggest that effective protection of azidothymidine- induced cardiopathology can be expected from drugs that are capable of targeting mitochondria. Therefore the present study in mice was carried out with mildronate, a cardioprotective drug of the aza-butyrobetaine class, which previously has been shown to act as a highly potent protector of mitochondrial processes. In our study, saline (control)…
Predicting the risk of drug–drug interactions in psychiatric hospitals: a retrospective longitudinal pharmacovigilance study
2021
ObjectivesThe aim was to use routine data available at a patient’s admission to the hospital to predict polypharmacy and drug–drug interactions (DDI) and to evaluate the prediction performance with regard to its usefulness to support the efficient management of benefits and risks of drug prescriptions.DesignRetrospective, longitudinal study.SettingWe used data from a large multicentred pharmacovigilance project carried out in eight psychiatric hospitals in Hesse, Germany.ParticipantsInpatient episodes consecutively discharged between 1 October 2017 and 30 September 2018 (year 1) or 1 January 2019 and 31 December 2019 (year 2).Outcome measuresThe proportion of rightly classified hospital epi…
The broad-spectrum antiinfective drug artesunate interferes with the canonical nuclear factor kappa B (NF-κB) pathway by targeting RelA/p65.
2015
Infection with human cytomegalovirus (HCMV) is a serious medical problem, particularly in immunocompromised individuals and neonates. The success of standard antiviral therapy is hampered by low drug compatibility and induction of viral resistance. A novel strategy is based on the exploitation of cell-directed signaling inhibitors. The broad antiinfective drug artesunate (ART) offers additional therapeutic options such as oral bioavailability and low levels of toxic side-effects. Here, novel ART-derived compounds including dimers and trimers were synthesized showing further improvements over the parental drug. Antiviral activity and mechanistic aspects were determined leading to the followi…
Drugs and Toxins Effects on the Liver
2011
Drug induced hepatotoxicity can be defined as a liver injury caused by drug or herbal medicines leading to liver test abnormalities or to a liver dysfunction with a reasonable exclusion of the other competing aetiologies. The liver has a central function in the metabolism of the xenobiotics, and as a result it may be susceptible to its toxic or idiosyncratic effects. While the overall incidence of drug induced liver injury (DILI) is infrequent (1 in 10.000 to 100.000 persons exposed), the impact is significant in the general population, with broad implications for patients, physicians, pharmaceutical industries and governmental regulatory agencies. DILI is the principle reason for the termi…
The impact of polypharmacy and drug interactions among the elderly population in Western Sicily, Italy.
2017
Aim: Primary endpoint was to report polypharmacy distribution in the general population vs ≥65 years old people and to examine the frequency of drug–drug interactions (DDIs) in the Health Local Unit of Palermo, Italy, in relationship with patients’ age. Methods: Drug prescription data for the year 2014 were extracted from the database of the Local Health Unit of Palermo Province, Italy. Patients were divided into five age groups (0–13, 14–64, 65–69, 70–74, and ≥75 year old). The detection of potential DDIs in polypharmacy profiles was performed with NavFarma software (Infologic srl, Padova, Italia), with DDI classification provided by tool Micromedex Drug Reax (Truven Health Analitics, Mich…
Gender difference in drug use in hospitalized elderly patients.
2015
Purpose The aims of this study were to evaluate whether or not there are gender differences in drug use at hospital admission and prescription at discharge and to evaluate the effect of hospitalization on medication patterns in the elderly. Method In-patients aged > 65 years included in the REPOSI registry during a recruitment period of 3 years (2008-2010-2012) were analyzed in order to evaluate drug use at hospital admission and prescription at discharge according to gender. Results A total of 3473 patients, 52% women and 48% men, were considered. Polypharmacy (> 5 drugs) is more frequent in men both at hospital admission and discharge. At hospital discharge, the number of prescripti…
