O objetivo deste estudo foi investigar a reemergência da coqueluche, notificação e casos confirmados da doença na mesorregião do campo das vertentes, microrregião de São João del-Rei e o estado de Minas Gerais, além de correlacionar o número de casos nessas regiões. Materiais e Métodos: Investigou-se a incidência no estado de Minas Gerais e no município de São João del-Rei, através da coleta de dados no TABNET, DATASUS, SINAN e boletins da Secretaria Municipal de Saúde de São João del-Rei (SMS-SJDR), durante o período compreendido entre 2008 a 2018, considerando os casos suspeitos e os confirmados da doença. Resultados: Os dados permitiram informar a comunidade dos municípios pesquisados fornecendo informações que poderão alertar e prevenir a reemergência dessa doença. Conclusão: O diagnóstico precoce permite sucesso no tratamento e diminuição das complicações da doença.

Introduction. The neurogenesis of the brain of young rats can be affected by several factors in their development, with the practice of physical exercises being an important factor in the neurogenesis of nervous tissue. Objective. To investigate the effects of different physical exercise protocols of medium and high intensity on neurogenesis in the brain of adolescent rats. Method. The experimental study, where three groups of animals were used: a control group (RC), a group that performed medium-intensity physical exercise (R1) and a group that performed high-intensity physical exercise (R2). Each group with 8 animals, totaling 24 animals. The progressive resisted physical exercise program on the vertical ladder was carried out for 4 weeks, 5 days a week with a duration varying between 30 and 45 minutes. After the end of the experiments, the animals were euthanized for removal of the brain and subsequent processing, staining using the Nissl method and histomorphometric analysis by counting neurons in the dentate gyrus of the hippocampus and subventricular zone. Results. The data demonstrated that there was no significant difference in the area and height of the apex of the hippocampal dentate gyrus between the groups (p=0.2474 and p=0.3337; respectively). The results of the length of the apex of the hippocampal dentate gyrus showed significant differences (p=0.0172). Conclusion. The practice of medium and high intensity progressive resisted physical exercises did not modify the morphology and neuronal density in the hippocampal dentate gyrus and subventricular zone of young rats.
