Barriers to early identification of autism in Brazil

Objective: Parents of children with autism spectrum disorders (ASD) seem to perceive that their child's development is not following the normal pattern as early as the first year of life. However, ASD children may not receive a diagnosis until they are of preschool age, especially in low- and middle-income countries. The objective of this study was to evaluate the pathway between initial parental concerns about atypical child development and ASD diagnosis in Brazil. Methods: Nineteen mothers whose children had been diagnosed with ASD participated and were interviewed. The ASD group consisted of two girls and 17 boys, with a mean age of 93.0 months (SD 48.4 monthsrange 39-197 months). Results: Mothers had their first concerns regarding ASD when children were 23.6 +/- 11.6 months old, but formal diagnosis occurred at a mean +/- SD age of 59.6 +/- 40.5 months, corresponding to a 3-year delay. Most mothers felt discouraged to address their concerns due to negative experiences with health professionals. Conclusion: In Brazil, mothers perceived the first signs of ASD in their children at an age similar to that reported in other countries, but the diagnosis of ASD seemed to be delayed. Consistent with the literature, mothers reported negative experiences with health professionals during the pathway to achieving ASD diagnosis.Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES)Univ Fed Sao Paulo UNIFESP, Dept Psiquiatria, Ambulatorio Cognicao Social Marcos Tomanik Mercad, Sao Paulo, SP, BrazilUniv Presbiteriana Mackenzie, Programa Posgrad Disturbios Desenvolvimento, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, Dept Psiquiatria, Ambulatorio Cognicao Social Marcos Tomanik Mercad, Sao Paulo, SP, BrazilWeb of Scienc

Fluid flow and structural numerical analysis of a cerebral aneurysm model

Intracranial aneurysms (IA) are dilations of the cerebral arteries and, in most cases, have no symptoms. However, it is a very serious pathology, with a high mortality rate after rupture. Several studies have been focused only on the hemodynamics of the flow within the IA. However, besides the effect of the flow, the development and rupture of the IA are also associated with a combination of other factors such as the wall mechanical behavior. Thus, the objective of this work was to analyze, in addition to the flow behavior, the biomechanical behavior of the aneurysm wall. For this, CFD simulations were performed for different Reynolds numbers (1, 100, 500 and 1000) and for two different rheological models (Newtonian and Carreau). Subsequently, the pressure values of the fluid simulations were exported to the structural simulations in order to qualitatively observe the deformations, strains, normal stresses and shear stress generated in the channel wall. For the structural simulations, a hyperelastic constitutive model (5-parameter Mooney–Rivlin) was used. The results show that with the increase in the Reynolds number (Re), the recirculation phenomenon is more pronounced, which is not seen for Re = 1. The higher the Re, the higher the strain, displacement, normal and shear stresses values.The authors acknowledge the financial support from the project EXPL/EME-EME/0732/2021, funded by the NORTE 2020 Portugal Regional Operational Programme, under the PORTUGAL 2020 Partnership Agreement, through the European Regional Development Fund (FEDER) and by Fundação para a Ciência e Tecnologia (FCT).

Tablet Use in Young Children is Associated with Advanced Fine Motor Skills

To evaluate whether frequent interactive tablet-use at preschool age is associated with improved fine motor skills and to describe tablet-use in young children. Cross-sectional study with 78 children, aged 24-42 months: group 1 with previous frequent tablet-use exposure (n = 26), group 2 without previous tablet-use exposure (n = 52). Fine motor skills were evaluated with the Bayley-III. Socioeconomic data and home environment quality were similar in both groups. Fine motor skills of group 1 were better than those of group 2 (p = 0.013). Most participating children carried out passive and active tablet activities, usually accompanied by parents, not exceeding time recommendations for young age. We observed a difference in fine motor skills in young children slightly favoring those with tablet-use experience

Nosso estudo investigou as respostas das comunidades de besouros de serapilheira ao processo de sucess?o florestal e varia??o temporal. O estudo foi conduzido na Esta??o Ecol?gica Tripu?, de julho (2001) a janeiro (2002). Avaliamos riqueza, abund?ncia, composi??o de esp?cies e flutua??o populacional dos grupos mais representativos no estudo. Foram coletados 3513 indiv?duos de 176 morfoesp?cies. Houve diferen?a de riqueza, abund?ncia e composi??o em rela??o ao est?gio sucessional e ?poca da coleta: floresta avan?ada nos meses de maior precipita??o apresentou riqueza e abund?ncia maiores, al?m de composi??o diferenciada. A flutua??o populacional nos grupos representativos pode ser explicada pela precipita??o. Conclu?mos que sucess?o e precipita??o afetam a comunidade de besouros e ? necess?rio conhecimento biol?gico do grupo estudado para coleta de dados confi?veis.Our study investigated the response of litter-dwelling beetle communities to forest successional stage and to temporal variation. The study was conducted in Esta??o Ecol?gica Tripu?, from July (2001) to January (2002). Here we evaluate richness, abundance, species composition and population fluctuation. We collected 3513 individuals of 176 morphospecies. We detected differences of richness, abundance and composition. Forests in the advanced stages of succession during the months with the highest rainfall, have higher richness and abundance. These forest also have own composition. Population fluctuation can be explained by rainfall. We conclude that both forest sucession and rainfall influence the beetle community. Biological knowledge of the group under study is necessary for confidence in data collection

Trends in legal and illegal trade of wild birds: a global assessment based on expert knowledge

Wildlife trade is a profitable economic activity. Birds are among the most heavily traded animals worldwide, with numerous species threatened by pet trade. Information on both legal and illegal aspects of trade and consumer demand is difficult to obtain across different countries, particularly given substantial socio-economic and cultural variation. Focusing on consumer demand in each country, we conducted a global survey among 105 international experts on bird conservation to identify expected trends, drivers and market characteristics of legal and illegal wild-caught pet bird trade. Our results suggest that future trends in legal bird trade will be mostly driven by socio-cultural motivations and intentional demand for wild-caught, rather than captive-bred birds. Bird popularity and rarity are the main factors expected to influence the choice of which bird species will be the most traded legally. Percentage of rural population was the main national-level socio-economic predictor for legal bird trade in the future. Demand for future illegal trade is expected to be driven by bird popularity and particular species identity. Experts consider illegal trade to be sustained mainly by consumers from higher socio-economic and educational backgrounds. Human population growth rate was the main national-level socio-economic predictor of illegal trade expected for the future. Legislation enforcement remains a critical issue in wildlife trade. Expanding trade networks and socio-economic changes continue to incorporate new regions into the wildlife trade. Investigating the multidimensional and synergistic determinants of wildlife trade will thus help address potential detrimental impacts bird trade might cause on biodiversity.This research was funded by FEDER Funds through the Operational Competitiveness Factors Program “COMPETE”, and by national funds through the Foundation for Science and Technology (FCT) within the framework of project “PTDC/AAG-GLO/0463/2014-POCI-01-0145-FEDER-016583”.

Attenuation of motor deficits by hydroethanolic extract of Poincianella pyramidalis in a Parkinson's disease model

The present study aimed to evaluate the possible neuroprotective effect of the hydroethanolic extract of Poincianella pyramidalis (EFIPp) (Tul.) L. P. Queiroz (Fabaceae), an endemic plant found in Northeastern Brazil, commonly used in folk medicine, on the motor deficits induced by repeated treatment with reserpine (RES) in rats. Adult male Wistar rats received 10 s.c. injections of 0.1 mg/kg RES or vehicle (VR), every 48 h, and daily i.p. injections daily of HEPp (25 mg/kg) or vehicle (VE). Throughout treatment, catalepsy behavior and oral movements were scored. After behavioral tests, superoxide dismutase (SOD) and catalase (CAT) activities were evaluated in the prefrontal cortex, hippocampus and striatum. RES treatment induced a progressive increase of catalepsy time in the treated group compared to control groups starting at day 15. RES also increased the number of vacuous chewing movements, tongue protrusions and duration of facial twitching. Treatment with HEPp attenuated the motor deficit in the catalepsy test and delayed the onset of oral movements induced by RES. No significant changes were observed in the antioxidant assay. Taken together, these results show a beneficial effect of HEPp on motor deficits induced by reserpine, suggesting a neuroprotective effect in a rat model of PD.Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq)Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES)Fundação de Apoio a Pesquisa e a Inovação Tecnologica do Estado de Sergipe (FAPITEC)Pro-reitoria de Pesquisa da Universidade Federal de Sergipe (POSGRAP/UFS)Univ Fed Sergipe, Dept Physiol, Sao Cristovao, SE, BrazilUniv Massachusetts, Neurosci & Behav Program, Amherst, MA 01003 USAMinist Educ, CAPES Fdn, BR-70040020 Brasilia, DF, BrazilUniv Fed Sao Paulo, Dept Biosci, Santos, SP, BrazilUniv Fed Sao Paulo, Dept Pharmacol, Sao Paulo, SP, BrazilUniv Fed Sergipe, Dept Biosci, Itabaiana, SE, BrazilUniv Fed Sao Paulo, Dept Biosci, Santos, SP, BrazilUniv Fed Sao Paulo, Dept Pharmacol, Sao Paulo, SP, BrazilWeb of Scienc
