- Compulsive sexual behavior and psychopathology among treatment-seeking men in Sao Paulo, Brazil(2013) SCANAVINO, Marco de Tubino; VENTUNEAC, Ana; ABDO, Carmita Helena Najjar; TAVARES, Hermano; AMARAL, Maria Luiza Sant'Ana do; MESSINA, Bruna; REIS, Sirlene Caramello dos; MATTINS, Joao Paulo Lian Branco; PARSONS, Jeffrey T.This study examined compulsive sexual behavior (CSB) and psychopathology in a treatment-seeking sample of men in Sao Paulo, Brazil. Eighty-six men (26% gay, 17% bisexual, 57% heterosexual) who met diagnostic criteria for excessive sexual drive and sexual addiction completed assessments consisting of the Mini International Neuropsychiatric Interview, a structured clinical interview for DSM-IV Axis I Disorders Clinical Version (segment for Impulse Control Disorder), Sexual Compulsivity Scale (SCS), and questions about problematic CSB. The average SCS score for our sample was above the cut-off score reported in other studies, and 72% of the sample presented at least one Axis I psychiatric diagnosis. There were no differences among gay, bisexual, and heterosexual men on SCS scores and psychiatric conditions, but gay and bisexual men were more likely than heterosexual men to report casual sex and sex with multiple casual partners as problematic behaviors. SCS scores were associated with psychiatric co-morbidities, mood disorder, and suicide risk, but diagnosis of a mood disorder predicted higher SCS scores in a regression analysis. The study provides important data on the mental health needs of men with CSB in Sao Paulo, Brazil.
- Family-Based Association Analysis of Serotonin Genes in Pathological Gambling Disorder: Evidence of Vulnerability Risk in the 5HT-2A Receptor Gene(2013) WILSON, David; LOBO, Daniela Sabbatini da Silva; TAVARES, Hermano; GENTIL, Valentim; VALLADA, HomeroPathological gambling (PG) has become a growing public health problem in many countries around the world. PG is an impulse control disorder and its behavior and psychopathology present similarities with substance abuse disorders. Evidence from twin studies supports a significant genetic predisposition to PG, but the precise genetic loci still remain unclear. The present study investigates the allele and genotype distribution of polymorphisms of the serotonin transporter, serotonin receptor 1B and 2A genes in 140 sib-pairs discordant for the diagnosis of PG. A significant association of the C/C genotype of the serotonin receptor 2A T102C (rs 6313) polymorphism and the PG phenotype was observed [OR = 1.7 (1.1-3.4)]. This preliminary result is consistent with the hypothesis that the serotonin system is associated with addiction behavior and similar results have been reported for nicotine and alcohol dependence.

A.; NOGUEIRA, M.; TAVARES, H.- Evaluation of a Physical Activity Program for Pathological Gamblers in Treatment(2013) ANGELO, Daniela Lopes; TAVARES, Hermano; ZILBERMAN, Monica LevitIt has been demonstrated that craving for gambling is associated with anxiety and depression in pathological gamblers. Exercise has been shown to reduce anxiety and depression, as well as positively influence abstinence rates in individuals with substance use disorders. In this study, we examined the impact of a physical activity program in 33 pathological gamblers. We also analyzed the association between craving and plasmatic levels of stress hormones (adrenocorticotropic hormone, cortisol, and prolactin). The program involved eight 50-min sessions. Craving was assessed 24 h before, immediately before, and immediately after each session, as well as on a weekly basis. Before and after the program, we evaluated gambling behavior, depressive symptoms, anxiety, and plasma levels of stress hormones. We identified a significant reduction in craving following each session and at the end of the program. There was improvement in anxiety, depressive symptoms, and gambling behavior. The post-session reduction in craving was accompanied by post-program reductions in craving and anxiety but not by a post-program reduction in depressive symptoms. The craving reduction was associated with a variation in prolactin levels but not with variations in levels of cortisol or adrenocorticotropic hormone.
