Abstract Introduction Drug-related crimes, especially drug trafficking, account for a large part of incarcerations not only in Brazil, but also worldwide. It is not clear whether the change in the drug law has contributed to the increase in the number of drug trafficking prisoners. Few studies have investigated gender differences and the growth of drug trafficking offenses in the Brazilian southern state of Rio Grande do Sul. Objective To investigate the growth of the prison population in the state of Rio Grande do Sul, emphasizing incarcerations for drug trafficking and gender differences. Method This was an ecological study using secondary data collected from official databases of the Brazilian National Penitentiary Department (Departamento Penitenciário [DEPEN]), affiliated with the Brazilian Ministry of Justice. Results Between 2006 and 2015, incarcerations increased by 27% (25% men, 83% women). Incarcerations for drug trafficking accounted for 11% of total arrests in 2006 (11% men, 20% women) and 45% in 2015 (47% men, 91% women), corresponding to an increase of 427% (415% among men, 723% among women). Conclusions Imprisonment for drug trafficking has increased considerably, especially among women. This may be due to factors such as: increase of drug trafficking, increase in the numbers of gangs in the state, and changes in the Brazilian drug law. These results highlight an emerging challenge in public health from the perspective of human rights and gender.

Objectives: Depressive symptoms are associated with worse outcomes in patients with bipolar disorder (BD). However, scarce data are available regarding neurocognitive profiles across different areas of functioning among BD patients with moderate and severe depression. Our objective was to assess cognition and global functioning in a group of patients with bipolar depression. Methods: Data were available for 100 patients with bipolar depression (78% female) and 70 controls (64% female) paired by age and education level. Cognitive function was assessed with a neuropsychological test battery. Functioning was assessed with the Functioning Assessment Short Test. Results: In patients, severe depression was associated with poorer cognitive performance on measures of executive function. Patients with severe depression showed worse global functioning than those with moderate depression (z = 2.54, p = 0.011). In patients with severe depression, lower global functioning was associated with lower scores in working memory (r = -0.200, p = 0.010), and executive function (r = -0.210, p = 0.007; and r = 0.293, p < 0.001). Conclusion: Our findings suggest cognitive impairment and global functioning impairment are associated with the severity of depressive symptoms in bipolar depression. Intensive treatment of depressive symptoms in patients with BD is crucial to improve cognitive functioning and, consequently, functional outcomes.

Objective: To assess differences in executive functioning between children and adolescents with attention-deficit/hyperactivity disorder (ADHD) comorbid or not with bipolar disorder (BD), and to study the neuropsychological profile of subjects with the comorbidity in a clinical sample from a developing country. Method: Case-control study comparing 23 participants with BD + ADHD and 85 ADHD-only subjects aged 6 to 17 years old. Both groups were drug-free. Executive function domains were assessed with the Stroop Test, the Wisconsin Card Sorting Test, and the Continuous Performance Test II. Results: The group with juvenile BD + ADHD showed a significantly worse performance on the Stroop task, including time in color (p = 0.002), time in color-word (p < 0.001), interference, number or errors in color and color-word (p = 0.001), and number of errors in word cards (p = 0.028). No between-group differences were found in other tests. Conclusions: Our findings suggest that ADHD-only and ADHD + BD do not show differences in inhibitory control and set-shifting domains. However, children and adolescents with BD and comorbid ADHD show greater impairment in processing speed and interference control. This suggests a potentially higher impairment in the dorsolateral prefrontal cortex and may be a potential neuropsychological signature of juvenile BD comorbid with ADHD.
