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…
Adolescent but not adult ethanol binge drinking modulates cocaine withdrawal symptoms in mice.
2016
Background Ethanol (EtOH) binge drinking is an increasingly common behavior among teenagers that induces long-lasting neurobehavioral alterations in adulthood. An early history of EtOH abuse during adolescence is highly correlated with cocaine addiction in adulthood. Abstinence of cocaine abuse can cause psychiatric symptoms, such as anxiety, psychosis, depression, and cognitive impairments. This study assessed the consequences of adolescent exposure to EtOH on the behavioral alterations promoted by cocaine withdrawal in adulthood. Methods We pretreated juvenile (34-47 days old) or adult (68-81 days old) mice with EtOH (1.25 g/kg) following a binge-drinking pattern. Then, after a three-week…
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.
Physical and cognitive doping in university students using the unrelated question model (UQM): Assessing the influence of the probability of receivin…
2018
Study objectives: In order to increase the value of randomized response techniques (RRTs) as tools for studying sensitive issues, the present study investigated whether the prevalence estimate for a sensitive item π̂$_{s}$ assessed with the unrelated questionnaire method (UQM) is influenced by changing the probability of receiving the sensitive question p. Material and methods: A short paper-and-pencil questionnaire was distributed to 1.243 university students assessing the 12-month prevalence of physical and cognitive doping using two versions of the UQM with different probabilities for receiving the sensitive question (p ≈ 1/3 and p ≈ 2/3). Likelihood ratio tests were used to assess wheth…
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 …
Drug use, family support and related factors in university students. A cross-sectional study based on the uniHcos Project data
2019
Objective: To assess the prevalence of illegal drug use in college students on any previous occasion, during the previous year and the previous month, and to analyze the relationship between illegal drug use and family support and other factors. Methods: A cross-sectional study using data from students participating in the uniHcos project (n = 3767) was conducted. The prevalence and age of onset of consumption of cannabis, non-prescription sedatives, stimulants and depressants was evaluated. Polyconsumption was also assessed. The independent variables were: family support, age, residence, and employment status. To determine the factors related to drug use multivariate logistic regression mo…
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…
¿Se ha modificado el uso de antitérmicos tras la introducción de ibuprofeno a diferentes concentraciones?
2014
Resumen: Introducción: Se analiza la utilización de antitérmicos en pediatría extrahospitalaria en España después de la aparición de medicamentos con 40 mg/ml de ibuprofeno. Pacientes y métodos: Estudio transversal, observacional y descriptivo en pacientes menores de 14 años con síndrome febril ya tratado, atendidos en Urgencias del Servicio de Pediatría del Consorcio Hospital General Universitario de Valencia entre noviembre del 2012 y enero del 2013. Resultados: De 217 niños, 144 estaban tratados con paracetamol o ibuprofeno, 69 recibían ambos fármacos, y uno paracetamol y metamizol. Hubo un 58,7% de exposiciones a paracetamol y un 40,9% a ibuprofeno. En el 63,2% de los casos el uso de an…
Psychopharmakotherapie in Schwangerschaft und Stillzeit
1998
The primary purpose of this article is to review critically the literature on the use of psychotropic medications in pregnancy and during breast feeding in order to suggest strategies for the clinical management of these periods. Use of psychotropic medications during pregnancy may cause three complications: 1. teratogenicity, 2. perinatal syndromes (neonatal toxicity), and 3. postnatal behavioural sequelae (behavioural toxicity). The literature features few well-controlled studies concerning these points, so that the available information allows only few conclusions. Exposure to certain psychotropic drugs in utero may increase the risk for some specific congenital anomalies; there is mostl…
Extemporaneous formulations in Germany – relevance for everyday clinical practice
2017
Background Extemporaneous formulations broaden the spectrum of therapeutic options for topical treatment in particular and thus improve patient care. The latest amendment to the Regulation on the Operation of Pharmacies issued in 2012 brought about changes in prescribing and manufacturing practices. The aim of the present study was to assess the relevance of extemporaneous formulations in everyday clinical practice. Methods We used data from the German Institute for Drug Use Evaluation (DAPI) to analyze the prescribing practice for compounded preparations in Germany between the fourth quarter of 2011 and the third quarter of 2014. In doing so, we determined the total cost associated with ex…
