O exercício físico é conhecido por promover vários benefícios à saúde. Juntamente com a suplementação com óleo de uma fruta muito conhecida na região central da América do Sul, o pequi, argumenta-se que determinadas adaptações ao exercício físico podem ser potencializadas, como a melhora da composição corporal e a redução da pressão arterial. No entanto, poucos estudos estão disponíveis sobre esse assunto e não são conclusivos. Objetivo: investigar o efeito da suplementação com óleo de pequi associada à prática de exercícios físicos na composição corporal e na pressão arterial de indivíduos saudáveis. Métodos: Vinte e três sujeitos (30,2 ± 5,7 anos, 1,66 ± 0,09 m, 71,5 ± 15,4 Kg) foram alocados em dois grupos: exercício com suplementação (ExeS, n = 11) e exercício sem suplementação (Exe , n = 12). O ExeS e o Exe realizaram pelo menos duas sessões de exercícios por semana por um período de trinta dias. Além disso, o ExeS foi suplementado com 400mg / dia de cápsulas de óleo de pequi. A composição corporal e a pressão arterial foram analisadas antes e após a intervenção. As diferenças entre os grupos foram avaliadas por análise de variância de medidas repetidas adotando P <0,05. Resultados: O percentual de gordura corporal não diferiu (P> 0,05) entre ExeS e Exe, respectivamente, antes (31,5 ± 11,0% vs 31,9 ± 9,9%) e depois (30,9 ± 10,5% vs 31,5 ± 10,6%) da intervenção. A massa muscular e a pressão arterial também não apresentaram alterações significativas (P> 0,05) intra e intergrupos em ambos os momentos. Conclusão: a suplementação com óleo de pequi (400mg / dia) por trinta dias não influencia a composição corporal e a pressão arterial de indivíduos saudáveis ​​e fisicamente ativos.

Purpose Pragmatic language is important for social communication across all settings. Children adopted internationally (CAI) may be at risk of poorer pragmatic language because of adverse early care, delayed adopted language development, and less ability to inhibit. The purpose of this study was to compare pragmatic language performance of CAI from Asian and Eastern European countries with a nonadopted group of children who were of the same age and from similar socioeconomic backgrounds as well as explore the relationship among emotion identification, false belief understanding, and inhibition variables with pragmatic language performance. Method Using a quasi-experimental design, 35 four-year-old CAI (20 Asian, 15 Eastern European) and 33 children who were not adopted were included in this study. The children's pragmatic language, general language, and social communication (emotion identification of facial expressions, false belief understanding, inhibition) were measured. Comparisons by region of origin and adoption experience were completed. We conducted split-half correlation analyses and entered significant correlation variables into simple and backward regression models. Results Pragmatic language performance differed by adoption experience. The adopted and nonadopted groups demonstrated different correlation patterns. Language performance explained most of the pragmatic language variance. Discussion Because CAI perform less well than their nonadopted peers on pragmatic communication measures and different variables are related to their pragmatic performance, speech-language pathologists may need to adapt assessment and intervention practices for this population.

Abstract. Background: Studies have shown that postdischarge care for self-harm patients is effective in reducing repeated suicidal behaviors. Little is known about whether volunteer support can help reduce self-harm repetition and improve psychosocial well-being. Aim: This study investigated the efficacy of volunteer support in preventing repetition of self-harm. Method: This study used a quasi-experimental design by assigning self-harm patients admitted to the emergency departments to an intervention group with volunteer support and treatment as usual (TAU) for 9 months and to a control group of TAU. Outcome measures include repetition of self-harm, suicidal ideation, hopelessness, and level of depressive and anxiety symptoms. Results: A total of 74 cases were recruited (38 participants; 36 controls). There were no significant differences in age, gender, and clinical condition between the two groups at the baseline. The intervention group showed significant improvements in hopelessness and depressive symptoms. However, the number of cases of suicide ideation and of repetition of self-harm episodes was similar for both groups at the postintervention period. Conclusion: Postdischarge care provided by volunteers showed significant improvement in hopelessness and depression. Volunteers have been commonly involved in suicide prevention services. Further research using rigorous methods is recommended for improving service quality in the long term.

Abstract. This quasi-experimental study examined the effects of exposure to a computer game on arousal and subsequent task performance. After inducing a state of low arousal, participants were assigned to experimental or control conditions via self-selection. Members of the experimental group played a computer game for five minutes; subjects in the control group spent the same amount of time awaiting further instructions. Participants who were exposed to the computer game showed significantly higher levels of arousal and performed significantly better on a subsequent cognitive task. The pattern of results was not influenced by the participants' prior experience with the game. The findings indicate that mood-management processes associated with personal media use at the workplace go beyond the alteration of arousal and affect subsequent cognitive performance.
