This paper analyses the perceptions of Portuguese preschool teachers regarding the use of Digital Platforms and Technologies (DPTs) in preschool education, focusing on which DPTs are mostly used and with what aims, and on constraints felt in its use. The paper draws on data collected in a larger research project regarding the use of DPTs ) in schools, using a survey questionnaire applied in schools from the Portuguese mainland during 2020, answered by 75 preschool teachers. Results show that preschool teachers mostly use Microsoft Office applications and communication platforms to communicate with peers and families, and for administrative and pedagogical tasks. The constraints felt are associated with the need for training which would allow these professionals to use DPTs more effectively, and the need to upgrade and ensure technical maintenance of the existing equipment.

Trypanosomiasis is caused by a pathogenic protozoan of the genus Trypanosoma, being Trypanosoma vivax the most important agent for cattle. The aim of the present study was to demonstrate the expansion of T. vivax infection in different mesoregions of Minas Gerais, Brazil, and describe the clinicopathological findings of trypanosomiasis in cattle. The diagnosis was based on visualization of the parasite in blood smears and DNA detection of T. vivax in the blood of live cows and tissues of necropsied animals by the polymerase chain reaction (PCR). Thirty suspected herds were tested, of which 11 were positive for T. vivax. The most frequent clinical signs were anemia, apathy, drop in milk production, weight loss, reproductive disorders, and nervous signs. Concomitant diseases, such as malignant edema, pneumonia and increased cases of mastitis were associated with T. vivax infection. Three cows were necropsied and the most significant findings were low body condition score, pale mucous and spleen with white pulp hyperplasia. The results demonstrated the expansion of T. vivax infection in Minas Gerais, that PCR-associated blood smears are promising for diagnosis, and that other diseases often occur concomitantly to T. vivax infection in regions with trypanosomiasis in cattle.
