Resumo As pandemias, como a da COVID-19, afetam uma quantidade relativamente grande de pessoas e impõem novas regras e hábitos sociais para a população mundial. As informações sobre a pandemia são constantes na mídia. Além disso, o distanciamento social foi adotado no Brasil como medida de prevenção da disseminação da COVID-19, o que pode ter consequências econômicas e psicossociais. Nesse contexto, o objetivo deste estudo foi verificar os fatores associados a indicadores de sintomas de transtornos mentais em residentes do Rio Grande do Sul, durante o período inicial da política de distanciamento social decorrente da pandemia da COVID-19. O estudo foi aprovado pelo CONEP. Participaram 799 pessoas, com idades entre 18 e 75 anos (M = 36,56; DP = 12,88), 82,7% mulheres, que responderam um questionário sociodemográfico, de distanciamento social e ao Self-Report Questionnaire (SRQ-20). Os resultados indicaram que ter renda diminuída no período, fazer parte do grupo de risco e estar mais exposto a informações sobre mortos e infectados, são fatores que podem provocar maior prejuízo na saúde mental nesse período pandemia. Investigar determinantes sociais que contribuem para maior vulnerabilidade ao adoecimento mental da população é importante no campo da saúde coletiva para o planejamento de ações e políticas públicas.
As pandemias, como a de COVID-19, afetam uma quantidade relativamente grande de pessoas e impõem, pelo tempo que duram, novas regras e hábitos sociais para a população mundial. As informações sobre a pandemia são constantes na mídia. Além disso, o distanciamento social foi adotado também no Brasil como medida de prevenção da disseminação do novo coronavírus, o que pode ter consequências econômicas e psicossociais. Nesse contexto, o objetivo deste estudo foi verificar a associação entre o distanciamento social, impacto na renda familiar e exposição a informações com os indicadores de sintomas de transtornos mentais em residentes do estado do Rio Grande do Sul durante a pandemia de COVID-19. O estudo foi aprovado pelo CONEP. Participaram 799 pessoas, com idades entre 18 e 75 anos (M = 36,56; DP = 12,88), 82,7% mulheres, que responderam um questionário sociodemográfico e sobre o distanciamento social, além do Self-Report Questionnaire (SRQ-20). Os resultados indicaram que não ser trabalhador da saúde, ter renda diminuída no período, fazer parte do grupo de risco e estar mais exposto a informações sobre mortos e infectados, são fatores que podem provocar maior prejuízo na saúde mental nesse período pandemia. Discute-se esses fatores e sua associação ao distanciamento social.
The WHOQOL-BREF instrument shows suitable psychometric performance in a sample of Brazilian older adults, becoming a useful alternative in the measurement of quality of life in this population.
In this study, minor depression has been significantly associated with lower life satisfaction and worse indexes of life quality. The results supported the current concept that minor depression is prevalent in later life, especially among the oldest-old. Subjects with minor depression had worse self-reported opinions about memory and sleep patterns, but when these variables were objectively measured, no meaningful differences could be determined by the research team. Female gender and the concurring presence of generalized anxiety disorder were both significantly associated with the presence of minor depression diagnosis.
Polyunsaturated fatty acids (PUFAs), especially the n-3 series, are known for their protective effects. Considering that cardiovascular diseases are risk factors for dementia, which is common at aging, the aim of this study was to evaluate whether fatty acid status in the elderly was associated with cognitive function and cardiovascular risk. Forty-five elderly persons (age ≥60 years) were included and divided into two groups based on their Mini-Mental Status Examination score adjusted for educational level: the case group (n = 12) and the control group (n = 33). Serum fatty acid composition, homocysteine (Hcy), hs-CRP, lipid profile and different cognitive domains were evaluated. The case group, characterized by reduced cognitive performance, showed higher levels of 14:0, 16:0, 16:1n-7 fatty acids and lower levels of 22:0, 24:1n-9, 22:6n-3 (DHA) and total PUFAs compared to the control group (p < 0.05). The n-6/n-3 ratio was elevated in both study groups, whereas alterations in Hcy, hs-CRP and lipid profile were observed in the case group. Cognitive function was positively associated with the 24:1n-9, DHA and total n-3 PUFAs, while 14:0, 16:0 and 16:1n-7 fatty acids, the n-6/n-3 ratio and Hcy were inversely associated. In addition, n-3 PUFAs, particularly DHA, were inversely associated with cardiovascular risk, assessed by Hcy levels in the elderly.
OBJECTIVE: In the present study, we investigate the association between the val66met polymorphism of the brain-derived neurotrophic factor (BNDF) and the performance on the Wisconsin Card Sorting Test in a sample of Caucasian Brazilian patients with bipolar disorder. METHOD: Sixty-four patients with bipolar disorder were assessed and their performance on the Wisconsin Card Sorting Test was compared with the allele frequency and genotype of the val66met polymorphism of the brain-derived neurotrophic factor. RESULTS: The percentage of non-perseverative errors was significantly higher among patients with the val/val genotype. There was no association between (BNDF) genotype frequency and other Wisconsin Card Sorting Test domains. CONCLUSION: Our results did not replicate previous descriptions of an association between a worse cognitive performance and the presence of the met allele of the val66met brain-derived neurotrophic factor gene polymorphism.
Estimation abilities are a group of processes that involve functions such as planning, attention, abstract reasoning, and also mnemonic processes, like semantic and working memory. They are allocated in order to solve problems for which the answers are not readily available. Estimation abilities can be measured using the Cognitive Estimation Test (CET). The aim of this article was to review the use of the CET and other tests of cognitive estimation in healthy and pathological populations. We discussed studies examining correlations between the CET and other measures of executive functions and the importance of the standardization of measures that assess estimation abilities.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
