Association of Parental Support with Reduced Stereotypy in Children with Autism Spectrum Disorder: A Cross-Sectional Study.

Background and Objectives: To analyze the influence of parental presence and use of risperidone on social interaction and apathy among patients with Autism Spectrum Disorder (ASD). Materials and Methods: Cross-sectional study in a reference center for patients with ASD in a city in northeastern Brazil. The research was carried out using a sociodemographic questionnaire, the Dimensional Apathy Scale, and the Social Communication Questionnaire (SCQ) with the domains of social interaction, language, stereotypy, and communication. The referred questionnaire was answered by the parents or guardians of the children with ASD according to the DSM V criteria. Data were analyzed via independent t-test using the SPSS software version 20. Results: Interviews were conducted with 51 parents/guardians of autistic children with a mean age of 8.8 years (±2.95) and a predominance of males, 34 (66.7%). Of this total, 49 (96.1%) of the children attended school; 40 (78.4%) children were on medication, of which 38 (74.5%) were on risperidone. Those children on risperidone had a higher score on the SCQ scale (p = 0.049) and on the domain of stereotyped behaviors (p = 0.033), which indicated greater impairment. Another statistically relevant variable was the presence of married parents, whereby children who did not have the presence of married parents had a higher average of stereotyped behaviors compared to those who had married parents. Conclusions: The results showed differences in the means of social interactions for children on risperidone, especially regarding stereotyped behaviors. However, it is not possible to state whether this difference was due to the use of risperidone or whether they used risperidone precisely because of these behaviors. Also important was that children who had the presence of married parents showed fewer stereotyped behaviors. There was no difference in apathetic behavior between children.

Hypokinetic Activity of Menthofuran on the Gastrointestinal Tract in Rodents.

The acute toxicity and hypokinetic activity induced by menthofuran on the gastrointestinal tract of rodents were investigated in the present study. An absence of acute toxicity was observed. Menthofuran delayed gastric emptying at oral doses of 25, 50, and 100 mg/kg in the experimental model of phenol red, as well as it reduced the intestinal transit at oral doses of 50 and 100 mg/kg. Interestingly, a scopolamine-similar hypokinetic effect was observed for menthofuran. In the experimental model of castor oil-induced intestinal hypermotility, menthofuran (50 and 100 mg/kg) reduced the number of loose stools as observed for the normal group. Additionally, menthofuran induced a marked concentration-dependent relaxation in rat ileum segments precontracted with KCl (EC50 = 0.059 ± 0.008 µg/mL) or carbachol (EC50 = 0.068 ± 0.007 µg/mL). These results suggest the possible decrease of calcium influx underlying the effects of menthofuran on the gastrointestinal tract, which opens the door for further study regarding this potential application for the treatment of gastrointestinal disorders, noting possible limitations of its use due to adverse effects in children.

Cognitive Health and Differential Cortical Functioning in Dissociative Trance: An Explorative Study About Mediumship.

Aim: To evaluate the cognitive functioning of subjects practicing trance mediumship in Brazil. Method: The study was based on the measurement of cognitive functions of 19 spirits mediums through neuropsychological tests such as the Brief Cognitive Screening Battery (BCSB), the Verbal Fluency Test (FAS), the digit span test, the cube test, the five digit test (FDT) and an evaluation of mental health through scales such as the Beck Depression Inventory (BDI), the Self-Report Questionnaire (SRQ), and the Trauma History Questionnaire (THQ). The sample included the participation of spirit mediums divided into two groups. The more experienced group (MEG) with 11 subjects had more than 10 years of mediumistic practice, while the other less experienced group (LEG) with 8 subjects had 1-5 years of experience. The inclusion criteria were psychophonic mediums (who have the ability to communication when deceased beings communicate directly via speaking) with regular trance practices for at least one year. The data collected were analyzed using the SPSS statistical package. Results: Regarding performance on the BCSB and digit span test, all subjects reached scores at the median or higher in comparison to standardized scores of Brazilians. Scores of 90% on the cube test and 42% on the FAS were reached in comparison to median or higher values, versus the median of standardized scores among Brazilians. On the FDT, we found statistical significance (p = 0.038) in the choice stage, with higher performance of subjects whose initial age of trance recognition occurred before 21 years old. On the BDI scale, no participant met the criteria for major depression. The SRQ showed an incidence of common mental disorders in 21% of the sample, which was more prevalent in the LEG (p = 0.008). Conclusion: The cognitive functioning of subjects who practice trance mediumship in Brazil is associated with cognitive health. Executive dysfunction may be a tendency in LEG. However, an incidence of common mental disorders in the LEG was observed. Executive processing was higher in the subgroup with early practices of recognizing the phenomenon.

Avaliação da atividade antioxidante total de chás comercializados em sachês / Evaluation of the total antioxidant activity of tea commercialized in saches

Os Antioxidantes são substancias que retardam o aparecimento de alterações oxidativas tanto nos seres vivos como nos alimentos. Quimicamente, são compostos aromáticos que contém em sua estrutura, pelo menos, um grupamento hidroxila. Estes podem ser naturais ou sintéticos, sendo o último amplamente utilizado na indústria alimentícia como conservante. O consumo de alimentos ricos em antioxidantes, como chás, vinhos e frutos foi relacionado com a baixa incidência de doenças degenerativas. Assim, objetivou-se neste estudo investigar a atividade antioxidante de chás processados frente ao DPPH (1,1-Diphenyl-2-picryl- hydrazyl). Para tanto, selecionaram- se 05 tipos de chá processados, comercializados no comercio formal da cidade de Teresina, Piauí, Brasil. A determinação da Atividade Antioxidante Total (AAT) se deu a partir dos extratos etanólicos obtidos das amostras com leituras em espectrofotômetro a 517nm. Os resultados revelam uma distribuição da ATT nas amostras variando de 19 a 84%. Observou-se, ainda, que o Boldo do Chile registrou a maior média dentre os demais. De uma forma geral, os chás são uma boa fonte de antioxidantes.(AU)
