Background: Little attention has been given to efficacious treatment and adherence to treatment of compulsive sexual behavior (CSB). Aims: Randomized controlled trial investigated short-term psychodynamic group therapy followed by relapse prevention group (STPGP-RPGT) and pharmacological treatment (PT) for CSB men on sexual compulsivity and adherence. Method: 135 men, 38 (SD = 9) years old on average, were randomly assigned to 1) STPGP-RPGT; 2) PT; 3) Both. Participants completed measures at baseline, 25th, and 34th week. 57 (42.2%) participants dropped out between baseline and 25th week, and 68 (50.4%) between baseline and 34th week. 94 (69.6%) did not adhere (80% pills taken or attended 75% therapy sessions). Results: A significant interaction effect was found between time and group (F (4, 128) = 2.62, P = 0.038, ES = 0.08), showing who received PT improved less in sexual compulsivity than those who received STPGP-RPGT (t = 2.41; P = 0.038; ES = 0.60) and PT þ STPGP-RPGT (t = 3.15; P = 0.007, ES = 0.74). Adherent participants improved more in sexual compulsivity than non-adherent at the 25th week (t = 2.82; P = 0.006, ES = 0.65) and 34th week (t = 2.26; P = 0.027, ES = 0.55), but there was no interaction effect, F (2, 130) = 2.88; P = 0.06; ES = 0.04). The most reported behavior (masturbation) showed greater risk of non-adherence (72.6%). Discussion and conclusions: Adherent participants improved better than non-adherent. Participants who received psychotherapy improved better than those who received PT. Methodological limitations preclude conclusions on efficacy. [ABSTRACT FROM AUTHOR]

Asexual, lesbian, gay, bisexual, and trans (ALGBT) individuals face worse life conditions and violence rates than their heterosexual cisgender counterparts. Brazil is often highlighted for having one of the highest rates of hate-related homicides against ALGBTs in the world. However, to date, Brazil's ALGBT population has not been investigated with a representative sample, and basic information such as population size or sociodemographic characteristics are mostly based in non-systematic data. We aimed to assess the proportion of asexual, lesbian, gay, bisexual, trans and non-binary adults in Brazil, their sociodemographic characteristics, and self-reported violence rates. In 2018, a sample (n = 6000) of the Brazilian adult population answered a face-to-face survey assessing sociodemographic characteristics, gender identity, sexual orientation, and self-reported psychological, physical, verbal, and sexual violence. Among Brazilian adults, 12.04% are ALGBT: 5.76% asexual, 0.93% lesbian, 1.37% gay, 2.12% bisexual, 0.68 trans, and 1.18% non-binary. Compared to heterosexual cisgender men, most ALGBT individuals have worse socioeconomic indicators and higher rates of self-reported psychological and verbal violence. All ALGBT groups and heterosexual cisgender women reported sexual violence more often than heterosexual cisgender men. It was reported between 4 up to 25 times more often by heterosexual cisgender women and trans individuals, respectively. The rates of the other ALGBT groups sit among the two. Our findings provide evidence of the important size of the ALGBT Brazilian population, as well as their socioeconomic vulnerability, and concerning violence levels experienced by the group. Policy makers may refer to the present article in order to mitigate this population's vulnerability and to better understand its sociodemographic characteristics. [ABSTRACT FROM AUTHOR]

TRANSGENDER people ,GENDER identity ,PSYCHOLOGICAL distress ,HEALTH policy ,SOCIODEMOGRAPHIC factors - Abstract
Studies estimate that gender-diverse persons represent 0.1 to 2% of populations investigated, but no such assessment was performed in Latin America. In a representative sample of Brazil's adult population (n = 6000), we investigated participants' sociodemographic characteristics and possible associations between these and current gender identity, categorized as cisgender, transgender or non-binary gender. We also investigated transgender individuals' distress associated with gender-related body characteristics. As main results, we found that transgender individuals represented 0.69% (CI95% = 0.48–0.90) of the sample, whereas non-binary persons were 1.19% (CI95% = 0.92–1.47). These percentages were not different among Brazil's 5 geographic regions. Preliminary analyses showed that transgender individuals were on average younger (32.8 ± 14.2 years, CI95% = 28.5–37.1), compared to cisgender (42.2 ± 15.9, CI95% = 42.5–42.8) and non-binary (42.1 ± 16.5 years, CI95% = 38.3–46.5) groups. Non-binary persons are less likely to be in a relationship compared to cisgender individuals (OR = 0.57, CI95% = 0.35–0.93). In the transgender group, 85% of transgender men and 50% of transgender women reported distress due to gender-related body characteristics. Our main findings draw attention that gender-diverse Brazilian individuals represent around 2% of the country's adult population (almost 3 million people), and are homogeneously located throughout the country, reiterating the urgency of public health policies for these individuals in the five Brazilian sub-regions.

Introduction: As COVID-19 develops around the world, numerous publications have described the psychiatric consequences of this pandemic. Although clinicians and healthcare systems are mainly focused on managing critically ill patients in an attempt to limit the number of casualties, psychiatric disease burden is increasing significantly. In this scenario, increased domestic violence and substance abuse have been recently reported. Objective: The objective of this study is to perform a systematic review of the literature regarding the consequences of severe acute respiratory syndrome-CoV-2 infection in terms of domestic violence and substance abuse, and compare incidences found. Materials and Methods: We conducted a literature search using the preferred reporting items for systematic reviews and meta-analyses guidelines. The keywords included "domestic violence," "substance abuse" AND "COVID-19," including multiple variants from December 2019 through June 2020. An extensive bibliographic search was carried out in different medical databases: Pubmed, EMBASE, LILACS, medRxiv, and bioRxiv. Titles and abstracts were reviewed according to the eligibility criteria. The risk of bias in the retrieved articles was assessed by the Joanna Briggs Institute's critical assessment instrument. Results: A total of 1505 papers were initially retrieved after consulting the selected databases. After browsing through titles and abstracts, 94 articles were initially included considering the predefined eligibility criteria. After a more detailed analysis, only six scientific articles remained in our selection. Of these, three were evaluating domestic violence against children, while the other three were about substance abuse. Conclusion: There is not enough evidence to support the concept that COVID-19 has led to an increase in the rates of domestic violence and substance abuse. The initial decrease in violence reports might not translate into a real reduction in incidence but in accessibility. Apparently, there has been a slight increase in alcohol and tobacco abuse, especially by regular users, which also requires confirmatory studies. The inconsistency between expert opinon articles and the actual published data could be a result of the limited time since the beginnging of the crisis, the fact that psychitaric patients have been chronically exposed to stressful situatons, and a possible stimulated increase in demand for psychatric consultations.

Epidemiological, behavioral, and clinical data on sexual compulsivity in Brazil are very limited. This study sought to adapt and validate the Sexual Compulsivity Scale (SCS), the 22-item version of the Compulsive Sexual Behavior Inventory (CSBI-22), and the Hypersexual Disorder Screening Inventory (HDSI) for use in Brazil. A total of 153 participants underwent psychiatric assessment and completed self-reported measures. The adaptation process of the instruments from English to Portuguese followed the guidelines of the International Society for Pharmacoeconomics and Outcomes Research. The reliability and validity of the HDSI criteria were evaluated and the construct validity of all measures was examined. For the SCS and HDSI, factor analysis revealed one factor for each measure. For the CSBI-22, four factors were retained although we only calculated the scores of two factors (control and violence). All scores had good internal consistency (alpha >.75), presented high temporal stability (>.76), discriminated between patients and controls, and presented strong (ρ > .81) correlations with the Sexual Addiction Screening Test (except for the violence domain = .40) and moderate correlations with the Impulsive Sensation Seeking domain of the Zuckerman Kuhlman Personality Questionnaire (ρ between .43 and .55). The sensitivity of the HDSI was 71.93 % and the specificity was 100 %. All measures showed very good psychometric properties. The SCS, the HDSI, and the control domain of the CSBI-22 seemed to measure theoretically similar constructs, as they were highly correlated (ρ > .85). The findings support the conceptualization of hypersexuality as a cluster of problematic symptoms that are highly consistent across a variety of measures. [ABSTRACT FROM AUTHOR]

This study aims to perform global gonadal and sexual function assessments in systemic lupus erythematosus-related antiphospholipid syndrome (SLE-APS) patients. A cross-sectional study was conducted in ten SLE-APS male patients and 20 healthy controls. They were assessed by demographic data, clinical features, urological examination, sexual function, testicular ultrasound, seminal parameters, sperm antibodies, and hormone profile. The median of current age was similar in SLE-APS patients and controls with a higher frequency of erectile dysfunction in the former group (30 vs. 0 %, p = 0.029). The median penis circumference was significantly reduced in SLE-APS patients with erectile dysfunction compared to patients without this complication (8.17 vs. 9.14 cm, p = 0.0397). SLE-APS patients with previous arterial thrombosis had a significantly reduced median penis circumference compared to those without this complication (7.5 vs. 9.18 cm, p = 0.039). Comparing SLE-APS patients and controls, the former had a significant lower median of sperm concentration (41.1 vs. 120.06 × 10/mL, p = 0.003), percentages of sperm motility (47.25 vs. 65.42 %, p = 0.047), normal sperm forms by WHO guidelines (11 vs. 23.95 %, p = 0.002), and Kruger criteria (2.65 vs. 7.65 %, p = 0.02). Regarding seminal analysis, the medians of sperm concentration and total sperm count were significantly lower in SLE-APS patients treated with intravenous cyclophosphamide vs. those untreated with this drug ( p < 0.05). Therefore, we have observed a novel association of reduced penile size with erectile dysfunction and previous arterial thrombosis in SLE-APS patients. Penis assessment should be routinely done in SLE-APS patients with fertility problems. We also identified that intravenous cyclophosphamide underlies severe sperm alterations in these patients.

The objective of this study is to evaluate the entries associated to the sexual function of patients undergoing physical disability rehabilitation, as well as the course of changes and medical approach through a retrospective review of medical charts. Methods: Medical records referring to the period between July and September, 1998 were evaluated. The data was divided into two groups, records containing physician’s entries on sexual function and/or entries of other health care professionals. The following aspects were investigated: whether complaints were spontaneously voiced by the patient, and whether diagnosis had been reached, with corresponding management. Results: Out of 245 medical records investigated, 17 (6.9%) contained clinical observations on the sexual function; out of those, 14 reached diagnosis. Twelve records (4.9%) had information by non-medical healthcare professionals. Out of 17 entries by doctors, 16 referred to male patients, which was found to be significant ( p = 0.0202). Conclusions: Records for the sexual function of patients undergoing physical rehabilitation are scarce. In this population, the sexual function of male patients had more extensive investigation on the part of physicians when compared to other health care professionals. [ABSTRACT FROM AUTHOR]

We admistered the International Index of Erectile Function (IIEF; Rosen et al., 1997) questionnaire to 30 patients with psychogenic erectile dysfunction (ED) at baseline, immediately after treatment, and 3 months after treatment. We randomized patients into three groups: group I, who had weekly sessions of time-limited theme-based group psychotherapy for 6 months and 50 mg sildenafil citrate orally on demand; group II, who had an intake of 50 mg sildenafl citrate orally on demand for 6 months only; and group III, who had weekly sessions of time-limited theme-based group psychotherapy for 6 months. We analyzed data (15-item IIEF) for each group at three times during the study and compared by the data using analysis of variance (ANOVA), followed by the Bonferroni multiple comparison test. We used Cochran's Q-test for analysis between baseline and posttreatment stages of patients with remission of symptoms (EF equal to or higher than 26 points). Group III had a mean score higher than group II, with the difference being statistically significant (immediately after treatment, p = 0.033; at 3 months after treatment, p = 0.049; p [ABSTRACT FROM AUTHOR]

Objective: There have been reports of obsessive-compulsive disorder (OCD) patients with comorbid paraphilias. In this paper, two cases of comorbidity between OCD and transvestism are reported with the aim of discussing possible explanations for this association. Method: Longitudinal case studies of two patients with OCD and tranvestism according to the DSM-IV were assessed using semi-structured interviews. Results: Both patients presented with OCD and comorbid transvestism with different clinical features and treatment response. The case whose cross-dressing was more egodystonic responded better to treatment. Conclusion: It is possible that some cases of transvestism are OCD-related while others are more related to a gender identity disorder. A dimensional approach focusing on common phenomenological and neurobiological substrates is suggested as particularly useful for clinical management and future research of both disorders.
