The use of benzodiazepines and the mental health of women in prison: a cross-sectional study.

In this article we assessed the prevalence of benzodiazepine (BZD) use in women before and during imprisonment, as well as its related factors and association with symptoms of anxiety, depression, and posttraumatic stress disorder in a quantitative, cross-sectional, analytical study of regional scope. Two female prisons in the Brazilian Prison System were included. Seventy-four women participated by completing questionnaires about their sociodemographic data, BZD use and use of other substances. These questionnaires included the Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), and Posttraumatic Stress Disorder Checklist-Civilian Version (PCL-C). Of the 46 women who reported no BZDs use before arrest, 29 (63%) began using BZDs during imprisonment (p < 0.001). Positive scores for PTSD, anxiety, and depression, as well as associations between BZD use during imprisonment and anxiety (p = 0.028), depression (p = 0.001) and comorbid anxiety and depression (p = 0.003) were found when a bivariate Poisson regression was performed. When a multivariate Poisson regression was performed for tobacco use, the PHQ-9 and GAD-7 scales, BZD use was associated with depression (p = p = 0.008), with tobacco use (p = 0.012), but not with anxiety (p = 0.325). Imprisonment increases the psychological suffering of women, consequently increasing BZD use. Nonpharmacological measures need to be considered in the health care of incarcerated women.

Elevated GABA levels in the medial prefrontal cortex and lower estrogen levels abolish cocaine sensitization behavior in ovariectomized female rats.

Animal models show that cocaine sensitization, a behavioral marker of addiction, is more significant in intact gonadal female than male rats and ovariectomy suppress this behavior in female rats. However, few studies explore changes in neurotransmission related to this phenomenon. Here we investigated the in vivo changes on GABA, glutamate, and taurine levels in the medial prefrontal cortex (mPFC) of gonadal intact or ovariectomized female rats after a cocaine challenge administration. Adult female rats were bilaterally ovariectomized (OVX), or sham-operated (SHAM) and randomly assigned to control (CTR), acute (ACT), or repeated (RPT) cocaine administration groups. In the challenge day, after eight days of daily cocaine (15 mg/kg) or saline administration and ten days of washout and stereotaxic surgery, RPT and ACT groups received cocaine, and the CTR group received saline. Horizontal locomotion was monitored concomitantly with microdialysate collection to determine extracellular GABA, glutamate, and taurine levels. Hormonal determination in blood samples confirmed the lower hormonal status of the OVX. Cocaine sensitization occurred in SHAM-RPT female rats after the challenge administration. Non-sensitized OVX-RPT rats showed a peak of GABA at 30 min after cocaine administration, with no change on glutamate and taurine levels. Therefore, elevated GABA levels in the mPFC and lower serum estrogen levels abolish cocaine sensitization behavior in ovariectomized female rats. We discuss some possible implications of these finding for future models of cocaine sensitization research lighting in the female hormonal influence.
