Avaliação da eficácia dos psicoestimulantes na intervenção do TDAH em crianças e adolescentes

This article presents a literature review on Attention Deficit Hyperactivity Disorder (ADHD) in children and adolescents, focusing on the effectiveness of psychostimulants in treating this condition. ADHD is a neurobehavioral condition characterized by symptoms of inattention, hyperactivity, and impulsivity. Psychostimulants, such as methylphenidate and amphetamine, are often prescribed for symptom control. This review addresses epidemiological aspects, definition, pathophysiology of the disease and medications, and discusses the results of studies on the effectiveness and safety of psychostimulants. It is concluded that psychostimulants are effective in treating ADHD, but long-term safety issues need to be considered.Este artigo apresenta uma revisão de literatura sobre o Transtorno do Déficit de Atenção e Hiperatividade (TDAH) em crianças e adolescentes, com foco na eficácia dos psicoestimulantes no tratamento dessa condição. O TDAH é uma condição neurocomportamental caracterizada por sintomas de desatenção, hiperatividade e impulsividade. Os psicoestimulantes, como o metilfenidato e a anfetamina, são frequentemente prescritos para o controle dos sintomas do TDAH. Esta revisão aborda os aspectos epidemiológicos, definição, fisiopatologia da doença e dos medicamentos, além de discutir os resultados de estudos sobre a eficácia e segurança dos psicoestimulantes. Conclui-se que os psicoestimulantes são eficazes no tratamento do TDAH, mas questões sobre sua segurança a longo prazo precisam ser consideradas

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans data set. Please cite this data paper when using its data in publications. We also request that researchers and teachers inform us of how they are using these data
