Abstract Background: Oxidative stress induced DNA damage has been assumed to contribute to the etiopathogenesis of schizophrenia (Sch). Smoking prevalence was more common in patients with Sch. The X-ray repair cross-complementation group 4 (XRCC4) gene plays an important role in the repair of DNA double-strand breaks. Objective: The purpose of this study was to investigate whether XRCC4 rs6869366 polymorphism has a relationship both in nicotine dependence (ND) and Sch+ND risk. Methods: One hundred and four patients with Sch+ND, 133 subjects with ND only and 70 healthy controls were enrolled in the study. XRCC4 rs6869366 polymorphism was analyzed using PCR-RFLP assay. Results: The frequency of XRCC4 rs6869366 GG genotype was more common in the ND and Sch+ND group than controls (p = 0.001 and p = 0.001, respectively). XRCC4 rs6869366 TT genotype was lower in both ND and Sch+ND group compared to controls (p = 0.001 and p = 0.001, respectively). Also, XRCC4 rs6869366 G allele was higher in Sch+ND group than controls (p = 0.001) while XRCC4 rs6869366 T allele was lower in ND group than healthy controls (p=0.001). XRCC4 rs6869366 GT genotype was lower in ND group than control group (p = 0.003). Discussion: These results suggested that the XRCC4 rs6869366 polymorphism G related genotype/allele was associated with susceptibility to both ND and Sch+ND in a Turkish population.

Abstract Background: Most of the clinical trials involving cognitive-behavioral therapy (CBT) for the treatment of anorexia nervosa (AN) used the individual therapy format, and few have been dedicated to adapting and assessing the effects of the group format. Objectives: To assess the applicability and effects of a group CBT program for Brazilian adolescents with AN. Methods: Open clinical trial with 22 patients with AN divided into an intervention group – IG (n = 11; CBT, psychiatry, nutrition and family psychoeducation-6 months) and a control group – CG (n = 11; psychiatry, nutrition and family psychoeducation-6 months). Data collected at baseline, at the end of groups and six months after the completion were: weight, height, body mass index and Eating Disorder Examination Questionnaire (EDE-Q) used to assess the severity of AN symptoms. Results: Baseline homogeneous groups, with 91% adherence in the IG vs. 54% in the CG (p = 0.05). Participants in both groups regained weight and decreased symptoms of eating disorders at the end of groups. Comparing the EDE-Q scores IG presented a statistically significant difference in the restraint subscale of the EDE-Q between the end-of-group and the follow-up (p = 0.01). Discussion: Group CBT program produced positive effects and was applicable in Brazilian adolescents with AN as an adjuvant to multidisciplinary treatment.

Abstract Background: There is a growing interest on the impact of comorbid obsessive-compulsive symptoms (OCS) on the course and severity of schizophrenia in recent years. Objective: This study determined the prevalence of OCS in schizophrenia patients and the clinical outcomes of the comorbidity. Methods: A total of 220 schizophrenia patients were recruited. All the participants completed Structure Clinical Interview version, Yale Brown Obsessive Compulsive Scale, Calgary Depression Scale for Schizophrenia, Columbia Suicide Severity Rating Scale and World Health Organization Quality of Life – Brief Version (WHOQOL-BREF). Results: Significantly higher number of schizophrenia patients with OCS were taking Clozapine (p = 0.023) and antidepressants (p = 0.013). Schizophrenia patients with OCS showed more severe positive (p < 0.001) and general symptoms (p < 0.001) of schizophrenia, higher depressive symptoms (p = 0.013), higher suicidality (p < 0.001), more hospitalization (p = 0.044), poorer physical (p = 0.034) and psychological (p = 0.032) domain in WHOQOL-BREF. Discussion: Schizophrenia patients with OCS are associated with more severe psychopathology and depressive symptoms which subsequently suffered poorer physical and psychological health. Hence, recognition of OCS in schizophrenia and early initiation of effective treatment may be able to reduce the burden for people with chronic mental illness.

Abstract Background: There is a vast literature investigating the possible associations between competitive anxiety, athlete variables and sports context. As far as we are concerned, there is no study which has compiled such findings to produce more robust evidence on this topic. Objectives: The aim of the study was to conduct an exploratory systematic review of the literature followed by a meta-analysis in order to investigate possible associations between competitive anxiety, social-demographic characteristics, profile of the athlete and sports context. Methods: Systematic searches of PubMed, PsycInfo, Web of Science, Lilacs and SciELO electronic databases were performed to identify studies published between January 2006 and January 2018, including a manual search in the references of the selected studies. Results: A total of 59 studies were included for qualitative synthesis and 27 for meta-analysis. More robust associations were observed between competitive anxiety and female gender, lower age, and less experience time. Discussion: Knowing the variables which exert influence on competitive anxiety can be relevant to plan specific treatment and intervention programs, enabling the athlete's development beyond technical and physical preparation.
