[Post-exposure prophylaxis against HIV, do we use our resources appropriately?] / Profilaxis post-exposición frente VIH, ¿utilizamos adecuadamente nuestros recursos?

OBJECTIVE: Post-exposure prophylaxis (PEP) against human immunodeficiency virus can be occupational, non-occupational or vertical transmission. The aim of our study was to analyse the indication and treatment carried out in a hospital. METHODS: Retrospective observational study that included all patients who received PEP between 2006 and 2014. The project was approved by the Committee for Ethics in Clinical Research. RESULTS: We evaluated 54 PEP, which were started at 11.8 hours' average. The antiretroviral drugs were adequately chosen, but the duration pattern did not adjusted to the recommendations published at that time. Tolerance was good, being gastrointestinal symptoms the most frequent adverse effects; only once was necessary to replace the pattern. There were usual losses during follow up, reaching in some subgroups 50%. CONCLUSIONS: Indication and choice of drugs were adequate in the three kinds of contact risks, but monitoring should improve.

Clinical features of pathological gambling in an addictions treatment cohort.

This study examined the prevalence and descriptive psychopathology of pathological gambling in a heterogeneous treatment sample of 372 substance users. About 14% of male participants and 10% of female participants were identified as presumptive pathological gamblers (PGs) on the South Oaks Gambling Screen (SOGS). The authors contrasted 49 PGs with 323 participants who were not pathological gamblers (NPGs) on a host of variables measuring premorbid risk, pathological patterns of substance use, consequences of use, and psychiatric comorbidity. PGs showed more disturbance than NPGs on some measures of premorbid risk, pathological substance use, social consequences of use, and psychiatric comorbidity. Gambling status may be an important comorbid condition in addictions treatment settings and a significant covariate in research.

Toward the DSM-V: the Withdrawal-Gate Model versus the DSM-IV in the diagnosis of alcohol abuse and dependence.

The Diagtnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994) classifies as dependent many cases of mild alcohol problems. DSM-IV diagnoses have modest relationships with predictive and some concurrent validators and often improperly sequence the onset of abuse versus dependence, perhaps due to insufficient emphasis on physiological features. Testing reliability, syndrome prevalence, syndrome sequencing, and concurrent and predictive validity, this study contrasted the DSM-IV with the Withdrawal-Gate Model (WGM), in which alcohol withdrawal is necessary and sufficient for the dependence diagnosis. Clinical samples of adults (baseline n = 318) and adolescents (baseline n = 214) meeting abuse or dependence were assessed for DSM-IV alcohol symptoms and external measures of problem severity and reinterviewed at 6 (adults) and 12 months (adults and adolescents). Among DSM-IV dependent cases, the WGM shifted 32% of adults and 80% of adolescents to the abuse category, making both categories more symptomatically severe, but had a negligible effect on the prevalence of total alcohol diagnoses. The WGM was more reliable than the DSM-IV and temporally sequenced abuse before dependence in a greater number of cases. The WGM was superior to the DSM-IV in concurrent and predictive validity on most measures. Future diagnostic systems may be more reliable and valid if they require evidence of withdrawal for substance dependence.
