What users think about the differences between caffeine and illicit/prescription stimulants for cognitive enhancement
2012
Pharmacological cognitive enhancement (CE) is a topic of increasing public awareness. In the scientific literature on student use of CE as a study aid for academic performance enhancement, there are high prevalence rates regarding the use of caffeinated substances (coffee, caffeinated drinks, caffeine tablets) but remarkably lower prevalence rates regarding the use of illicit/prescription stimulants such as amphetamines or methylphenidate. While the literature considers the reasons and mechanisms for these different prevalence rates from a theoretical standpoint, it lacks empirical data to account for healthy students who use both, caffeine and illicit/prescription stimulants, exclusively f…
The pathogenetic role of adulterants in 5 cases of drug addicts with a fatal outcome
2013
The purpose of the present study is to determine the role of lidocaine, caffeine and dextromethorphan, used as adulterant substances, in five cases of drug overdose which have come to our attention. Taking into account the pharmacological mechanism, blood concentration and route of administration (intravenous) we evaluated the hypothesis that these substances could act with a synergistic effect - or at least additive - with the illicit drugs on the central nervous system and cardiovascular system.
Increased liver stiffness is associated with mortality in HIV/HCV coinfected subjects: The French nationwide ANRS CO13 HEPAVIH cohort study
2019
Background The association between liver stiffness measurements (LSM) and mortality has not been fully described. In particular the effect of LSM on all-cause mortality taking sustained virological response (SVR) into account needs further study. Methods HIV/HCV participants in the French nation-wide, prospective, multicenter ANRS CO13 HEPAVIH cohort, with ≥1 LSM by FibroScan (FS) and a detectable HCV RNA when the first valid FS was performed were included. Cox proportional hazards models with delayed entry were performed to determine factors associated with all-cause mortality. LSM and SVR were considered as time dependent covariates. Results 1,062 patients were included from 2005 to 2015 …
Cannabis use in male and female first episode of non-affective psychosis patients: long-term clinical, neuropsychological and functional differences
2017
BACKGROUND: Numerous studies show the existence of a high prevalence of cannabis use among patients with psychosis. However, the differences between men and women who debut with a first episode of psychosis (FEP) regarding cannabis use have not been largely explored. The aim of this study was to identify the specific sex factors and differences in clinical evolution associated with cannabis use. METHOD: Sociodemographic characteristics at baseline were considered in our sample of FEP patients to find differences depending on sex and the use of cannabis. Clinical, functional and neurocognitive variables at baseline, 1-year, and 3-years follow-up were also explored. RESULTS: A total of 549 pa…
Evolution of patients’ socio-behavioral characteristics in the context of DAA: Results from the French ANRS CO13 HEPAVIH cohort of HIV-HCV co-infecte…
2018
International audience; BACKGROUND:Direct-acting antivirals (DAA) have dramatically increased HCV cure rates with minimal toxicity in HIV-HCV co-infected patients. This study aimed to compare the socio-behavioral characteristics of patients initiating pegylated-interferon (PEG-IFN)-based HCV treatment with those of patients initiating DAA-based treatment.METHODS:ANRS CO13 HEPAVIH is a national multicenter prospective cohort started in 2005, which enrolled 1,859 HIV-HCV co-infected patients followed up in French hospital outpatient units. Both clinical/biological and socio-behavioral data were collected during follow-up. We selected patients with socio-behavioral data available before HCV tr…
Evolución de la resistencia transmitida y adquirida a fármacos antirretrovirales en pacientes infectados con VIH-1
2018
Introducción: La adquisición y transmisión de resistencia amenaza el éxito del tratamiento antirretroviral. En este estudio evaluamos el comportamiento epidemiológico de las mutaciones de resistencia (MR) a fármacos antirretrovirales del VIH-1 según factores de riesgo y clínicos específicos. Metodología: Este es un estudio retrospectivo observacional de series transversales acumuladas, realizado en la Unidad de Enfermedades Infecciosas de un hospital universitario en España (CHGUV) entre los años 2003 y 2014. Nuestro objetivo fue estimar la evolución de la frecuencia anual de MR a fármacos antirretrovirales en el genoma de la proteasa y transcriptasa inversa del VIH-1 durante el periodo de …
Características sociales y clínicas de un grupo de madres infectadas por VIH en Valencia: influencia de la drogadicción parenteral
2000
Resumen Objetivo Al principio de conocerse la infeccion por el virus de la inmunodeficiencia humana (VIH), la causa mas importante de su transmision en las mujeres occidentales fue el consumo de drogas por via parenteral. El objetivo de nuestro trabajo consistio en describir las principales caracteristicas sociales y clinicas de un grupo de madres seropositivas, y en analizar su relacion potencial con el uso intravenoso de drogas. Metodos Realizamos un estudio observacional prospectivo con 220 mujeres infectadas por VIH que presentaban la particularidad de haber dado a luz ninos con riesgo de infeccion. Se incluyeron todas las madres reclutadas en la Unidad VIH de un hospital de Valencia qu…
Funcionamiento neuropsicológico en drogodependientes VIH/SIDA inmunodeprimidos: Importancia de la fase de la infección y del consumo de drogas
2000
Todavía no disponemos de factores de riesgo definitivos que permitan predecir la naturaleza y magnitud de las complicaciones neuropsicológicas asociadas a la infección por VIH. Con este trabajo nos planteamos estudiar la naturaleza del deterioro neuropsicológico asociado al VIH en drogodependientes con historia de consumo de drogas por vía intravenosa inmunodeprimidos, así como determinar la influencia que tienen sobre el mismo la fase clínica de la infección (asintomáticolSIDA) y el consumo de drogas. Para ello hemos utilizado una muestra de 20 drogodependientes voluntarios en distintas fases de la infección (A3 y C3). En cada uno de estos grupos la mitad de los sujetos se encuentra en abs…
Burden of HIV and hepatitis C co-infection: the changing epidemiology of hepatitis C in HIV-infected patients in France.
2015
Équipe UB/CHU (EA) Pôle MERS CT3 Hors Enjeu; International audience; Background & AimsTo better evaluate the HIV-HCV co-infection burden in the context of new effective HCV treatment. MethodsWe reviewed all the epidemiological data available on HCV-related disease in HIV-infected patients in France. Sources of data have been selected using the following criteria: (i) prospective cohorts or cross-sectional surveys; (ii) conducted at a national level; (iii) in the HIV-infected population; (iv) able to identify HCV co-infection and chronic active hepatitis C (HCV RNA positive); and (v) conducted during the period 2003-2012. ResultsThe overall prevalence of HIV-HCV co-infection has decreased fr…
Demographic and behavioural profiles of patients with common oral mucosal lesions by a homogeneity analysis
2012
Oral Diseases (2012) 18, 396–401 Objective: The aim of this study is to assess the main oral mucosal lesions (OMLs) within a hospital base and to provide an anamnestic, diagnostic model based on homogeneity analysis of some variables. Methods: The demographic and behavioural data (i.e. gender, age, smoking status, alcohol consumption and therapeutic drug usage) of 1753 patients with at least one OML were considered. Multiple correspondence analysis (MCA) and multivariate tests of the simultaneous marginal homogeneity hypothesis (SMH) were used to analyse the evidence of any differences between the demographic and behavioural profiles relating to OMLs diagnoses. Statistical significance of…
