Educational sessions in pharmacovigilance: What do the doctors think?

Background: The aim of this study was to determine physicians"opinion regarding pharmacovigilance feedback sessions. A survey was conducted in a teaching hospital, and the physicians who attended the sessions were invited to participate by filling out a structured questionnaire. All sessions included a review of adverse drug reactions identified at the hospital and information on pharmacovigilance issues (news on warnings released by regulatory agencies or drug toxicity problems identified by recently published studies in medical journals). The survey questions were related to the interest, satisfaction, and belief in the utility of the sessions. A Likert scale (0-10 points) was used to assess physicians" opinions. Findings: A total of 159 physicians attended the sessions and 115 (72.3%) participated in the survey. The mean (SD) age was 38.9 (12.1) years, and 72 (62.6%) were men. The mean (SD) scores of interest, satisfaction with the information provided, and belief in the utility of these sessions were 7.52 (1.61), 7.58 (1.46), and 8.05 (1.38) respectively. Significant differences were observed among physicians according to medical category and speciality in terms of interest, satisfaction, and belief in the utility of those sessions. Conclusions: Educational activities for physicians, such as feedback sessions, can be integrated into the pharmacovigilance activities. Doctors who attend the sessions are interested in and satisfied with the information provided and consider the sessions to be useful. Additional studies on the development and effectiveness of educational activities in pharmacovigilance are necessary.

«Me quedaré con lo positivo»: Análisis de blogs de mujeres con cáncer de mama

En este artículo se analizan siete blogs escritos por mujeres con cáncer de mama. En primer lugar, se indaga sobre su forma de concebir el cuerpo en relación, por un lado, al impacto del cáncer en los órganos y procesos corporales ligados a la feminidad y, por el otro, a su carácter mortal. En segundo lugar, se analiza su atribución de agencia en relación a la enfermedad y su curación. Se observa que la responsabilidad en la curación se atribuye principalmente a los médicos, pero aparece con fuerza la idea que la mujer se puede sanar mediante cambios en su estilo de vida y a través del pensamiento positivo. Este establece un marco en el que las afectadas de cáncer encuentran dificultades para reconocer y expresar aspectos considerados negativos del proceso como la rabia, la desesperación o el miedo a la muerte, al mismo tiempo que marca una distinción entre pacientes con trayectorias de éxito en su curación y los que no lo consiguen, que son culpabilizados.

Green tea catechin inhibits fatty acid synthase without stimulating carnitine Palmitoyltransferase-1 or inducing weight loss in experimental animals

Background: The enzyme fatty acid synthase (FASN) is highly expressed in many human carcinomas and its inhibition is cytotoxic to human cancer cells. The use of FASN inhibitors has been limited until now by anorexia and weight loss, which is associated with the stimulation of fatty acid oxidation. Materials and Methods: The in vitro effect of (-)-epigallocatechin-3-gallate (EGCG) on fatty acid metabolism enzymes, on apoptosis and on cell signalling was evaluated. In vivo, the effect of EGCG on animal body weight was addressed. Results: EGCG inhibited FASN activity, induced apoptosis and caused a marked decrease of human epidermal growth factor receptor 2 (HER2), phosphatidylinositol 3-kinase (PI3K)/AKT and extracellular (signal)-regulated kinase (ERK) 1/2 proteins, in breast cancer cells. EGCG did not induce a stimulatory effect on CPT-1 activity in vitro (84% of control), or on animal body weight in vivo (99% of control). Conclusion: EGCG is a FASN inhibitor with anticancer activity which does not exhibit cross-activation of fatty acid oxidation and does not induce weight loss, suggesting its potential use as an anticancer drug.

Doctors més enllà de la Universitat i els centres de recerca

Les causes d'aquest desajust no només estan a la Universitat i l'empresa, també l'administració hi té la seva part de responsabilitat. La Universitat i l'empresa s'han de conèixer, saber que fa cadascuna i col·laborar, però l'administració ha de propiciar i fomentar-ne la relació i això només es pot fer coneixent quins són els dèficits estructurals que ho dificulten i crear un marc i condicions per eliminar-los o, si més no, reduir-los. Una altra variable explicativa de la mala situació de la competitivitat és la nostra relativa poca producció de doctors respecte a d'altres països del nostre entorn que són més competitius

Anàlisi d'un spot televisiu segons el model proposat per Frederic Chaume : Estudi d'un cas: Beauty is nothing without brains

L’estudi de les situacions comunicatives sempre m’ha atret de manera significativa. El món de la publicitat, també. L’assignatura de Semiòtica audiovisual ha estat el vincle que ha inspirat el tema d’aquest treball. L’idea inicial era la d’analitzar des d’una perspectiva semiòtica un document audiovisual, concretament, Beauty is nothing without brains, un espot televisiu de Mercedes-Benz emès als Estats Units l’any 2007. Es pretenia identificar i analitzar cadascun dels elements que configuren la comunicació audiovisual i presentar possibles versions traductològiques del mateix. La dificultat de crear un esquema d’anàlisi que em permetés estructurar-ne l’estudi va conduir-me a Frederic Chaume. És llavors quan aconsegueixo concretar el tema del treball: es pretén analitzar aquest document audiovisual seguint el model proposat per Chaume, responent a un hipotètic encàrrec de traducció el qual demana la seva adaptació al mercat català.

¿Qué entienden los jóvenes universitarios por monogamia y sexo sin penetración, como estrategias preventivas de la transmisión sexual del virus del SIDA? = What university students understand by monogamy and sex without penetration as preventive strategies of sexual transmission of AIDS virus?

Monogamy and sex without penetration are behaviors recommended by the WHO to avoid AIDS virus sexual transmission. Seven hundred and fifty university students from 18 to 25 years (67.7% women) were surveyed and they were asked to give a maximum of three free definitions of the words monogamy and sex without penetration to prevent AIDS virus sexual transmission. Their participation was voluntary and anonymous. Although the majority of the answers was correct, there was a considerable percentage of wrong answers, either for monogamy (3.7% masturbation; 2.1% to have many partners; 0.9% homosexual relations), or for sex without penetration (20.5% oral sex; 1.1% anal coitus; 0.8% coitus without orgasm; 0.4% coitus interruptus). Some definitions or examples differ by gender. The amount of wrongs or incomplete answers put researchers on the alert about insufficient preventive knowledge in a population with a high educational level

Hospital doctors' views and concerns about pharmacovigilance

Purpose: The aim of the study was to evaluate the opinions and concerns of hospital doctors about adverse drug reactions (ADRs) and pharmacovigilance. Methods: A qualitative study was undertaken using focus groups in sessions on pharmacovigilance activities conducted in thirteen clinical services of a tertiary university hospital. A total of 296 physicians participated in these sessions by giving their opinions or expressing their doubts about ADR and pharmacovigilance activities which were recorded by different observers and subsequently analysed. Results: Doctors remarked on: a) the importance, concern, frequency and specific types of ADRs that were observed in clinical practice; b) problems of clinical decision making related to the suspected ADRs; c) methods for improving detection and reporting ADRs; d) monitoring of specific ADRs or ADRs caused by specific drugs; e) and measures to prevent and minimize the risk of ADRs. Physicians expressed doubts related to: a) the basic concepts of ADRs; b) the methods of ADR identification and evaluation; c) the objectives and procedures of pharmacovigilance programmes; d) and the impact of pharmacovigilance activities. Conclusions: Hospital doctors believe that ADRs are a matter for concern in their daily clinical practice, and monitoring ADRs as well as measures for preventing the risk of ADRs are needed. Nevertheless, doctors have doubts about what an ADR is, the accuracy of diagnostic methods, the development of pharmacovigilance activities and their impact on clinical practice. Pharmacovigilance should be better explained through a continuous feedback and close relationship with hospital doctors.
