Medico-administrative data like SNDS (Système National de Données de Santé) are not collected initially for epidemiological purposes. Moreover, the data model and the tools proposed to SNDS users make their in-depth exploitation difficult. We propose a data model, called the ePEPS model, based on health care trajectories to provide a medical view of raw data. A data abstraction process enables the clinician to have an intuitive medical view of raw data and to design a study-specific view. This view is based on a generic model of care trajectory, i...

Secondary use of medical and administrative databases has become a powerful tool for epidemiological studies. In that respect, the recent access opening of French nationwide health record database or SNDS (Système National des Données de Santé) is a great opportunity to carry out comprehensive health studies at the country level. However, using this database is far from being straightforward for non-expert data scientists; so, dedicated tools needed to be developed. Our contribution is focused on data management and visualization tools able to query and cope with the complexity of care pathways of patients...

Antipsychotic drugs possess side atropinic (anticholinergic) properties that may induce several adverse drug reactions (ADRs), such as memory loss or cognitive impairment. The aim of the present study was investigating anticholinergic burden in patients treated with antipsychotic drugs. All ADR reports including at least one antipsychotic and registered between 2000 and 2015 in the Midi-Pyrénées PharmacoVigilance Database were extracted and analyzed using the Anticholinergic Duran's list. The primary objective of this cross-sectional study was to calculate anticholinergic burden in antipsychotic-treated patients; the secondary one was to investigate associated factors...

Benign prostate hypertrophy (BPH) could be associated with low urinary symptoms requiring medical treatment: 5 alpha-reductase inhibitors (5-ARI) or ɑ-blockers. Two clinical trials investigating 5-ARI use in prostate cancer (PCa) primary prevention highlighted a potential safety signal with an increased risk of high grade PCa. Later observational studies failed to show similar results but have some limits. The present paper focuses on describing the protocol of the CANARI study and its feasibility, as regards the matching process of two pseudo-anonymous databases...

The use of ketamine (Ket) as a pharmacological model of schizophrenia is an important tool for understanding the main mechanisms of glutamatergic regulated neural oscillations. Thus, the aim of the current study was to evaluate Ket induced changes in the average spectral power using the hippocampal quantitative electroencephalography (QEEG). To this end, male Wistar rats were submitted to a stereotactic surgery for the implantation of an electrode in the right hippocampus. After three days, the animals were divided into 4 groups that were treated for 10 consecutive days with Ket (10, 50 or 100 mg/kg)...

Cardiac remodeling (cardiac hypertrophy and fibrosis) is a hall mark of heart failure (HF). It can be induced by the abnormal elevation of several endogenous factors including angiotensin II (Ang II), which is generated from its precursor angiotensin I (Ang I) by the action of angiotensin converting enzyme (ACE). The inhibition of this enzyme or the blockade of the Ang II receptors demonstrated a high clinical value against the progression of HF. Ang I and Ang II may also be converted into angiotensin 1-7 (Ang 1-7) and angiotensin 1-9 (Ang 1-9) respectively by the action of angiotensin converting enzyme-2 (ACE2)...

Chloroquine (CQ) induces histamine-independent itch in human and mice. We recently reported the role of intradermal nitric oxide (NO)/ cyclic guanosine monophosphate (cGMP) pathway in CQ-evoked scratching in mice. Chloroquine stimulates neuronal nitric oxide synthase (nNOS) activity to over-producing NO in the skin. Sumatriptan, a 5-hydroxytryptamine 1b/1d receptors (5-HTR1b/1d) agonist, is involved in pain and used to treat migraine and cluster headaches. According to previous studies, sumatriptan inhibits NOS activity...

REVIEW
Gisèle Pickering, Véronique Morel
Neuropathic pain (NP) is difficult to treat and is associated with a decline in quality of life. NP aetiologies are numerous and a number of pathologies display neuropathic characteristics. Of the various N-Methyl-D-Aspartate antagonists that are alternatives to recommended in first-line NP treatment, memantine has the safest side-effect profile and has long been approved in Alzheimer's disease. The review covers memantine studies in post-herpetic neuralgia, diabetic pain, postoperative pain, complex regional pain syndrome, chronic phantom limb pain, opioid refractory pain, and fibromyalgia...

The ability of quercetin to reverse an established cirrhosis has not yet been investigated. Therefore, the aim of the present study was to examine the efficacy of this flavonoid in reversing experimental cirrhosis. Cirrhosis was induced by intraperitoneal administration of TAA (200 mg/kg of body weight) three times per week for 8 weeks or by intraperitoneal petrolatum-CCl4 (400 mg/kg of body weight) administration three times per week for 8 weeks. To determine the capacity of quercetin to prevent liver fibrosis, the flavonoid (50 mg/kg of body weight, p...

Developing drugs for rare disease can be challenging due to specific rare disease characteristics. The French Medical Pharmacology is structured and positioned to play a major role in Orphan Drug Research and Development due to the required expertise concentrated into pharmacology departments, exclusively implemented within the French University Hospitals, public hospitals that are linked to a medical school (and often a pharmacy school) with numerous INSERM or CNRS labelled research units. In addition, these structures allow a close collaboration between researchers, academic institutions and biotech start-up (most of them being spin-off of the academic structures)...

The purpose of this study was to assess the impact of age and sex on the reporting of cough and angioedema related to renin angiotensin system (RAS) inhibitors. A case/non-case study was performed in VigiBase. Two case groups were identified, reports of cough and reports of angioedema and non-cases were all reports of all other adverse events. Logistic regression analysis was used to assess the association between reporting of cough and angioedema with each class of RAS inhibitors stratified by age/sex and to control for confounding...

In this study, we investigated the effect of bufalin on the human ether-à-go-go-related gene (hERG) K(+) channels using the perforated patch recording technique. We measured a half-maximal inhibitory concentration (IC50 ) of 24.83 μM and maximal inhibitory effect of 39.45 ± 1.14% with bufalin. These findings suggest that bufalin is a potent hERG K(+) channel blocker and may provide a new way for understanding Chan Su-induced arrhythmia. This article is protected by copyright.

We aimed to investigate the local anesthetic properties of naloxone alone or as an adjunct for the local anesthetic lidocaine. After the block of the cutaneous trunci muscle reflex (CTMR) with drugs delivery by subcutaneous infiltration, cutaneous nociceptive block was tested on the ratsꞌ backs. We demonstrated that naloxone, as well as lidocaine elicited cutaneous analgesia dose-dependently. The relative potency in inducing cutaneous analgesia was lidocaine [22.6 (20.1 - 25.4) μmol/kg] > naloxone [43...

Bisphenol A (BPA) is an endocrine disruptor with an oestrogenic activity that is widely produced for the manufacture of polycarbonate plastic, epoxy resin, and thermal paper. Its ubiquitous presence in the environment contributes to broad and continuous human exposure, which has been associated with deleterious health effects. Despite numerous controversial discussions and a lack of consensus about BPA's safety, growing evidence indicates that BPA exposure positively correlates with an increased risk of developing obesity...
