Este relato de experiência teve como objetivo apresentar algumas singularidades, travessias e potencialidades advindas da construção e do desenvolvimento do Programa de Terapia Ocupacional, Saúde e Trabalho (ProTost) em um hospital universitário durante os meses iniciais da pandemia. Esse programa foi orientado pelos princípios da Ergonomia da Atividade e da Psicodinâmica do Trabalho e pautou-se na necessidade de construção de ações participativas. Foram realizados grupos de reflexão sobre o trabalho envolvendo 15 setores do hospital e 140 trabalhadores. Os grupos proporcionaram aos trabalhadores espaços de escuta coletiva sobre o trabalho e ampliaram a visibilidade dos esforços empreendidos e os processos de reconhecimento horizontal e vertical. Além disso, contribuíram para o estudo de situações de trabalho, as discussões sobre transformações nos processos de trabalho e a construção de estratégias para enfrentamento dos desafios vivenciados no hospital que foram agravados pelo advento da pandemia.
The submucous plexus of the normal small and large intestine of Calomys callosus was studied by NADH and AChE histochemical techniques and by transmission and scanning electron microscopy.The plexus contains ( x _ ± SD) 7,488 ± 293 neurons/cm 2 in the duodenum, 5,611 ± 836 in the jejunum, 2,741 ± 360 in the ileum, 3,067 ± 179 in the cecum, and 3,817 ± 256 in the proximal colon. No ganglia or nerve cell bodies were seen in the esophagus, stomach, distal colon or rectum. The neurons are pear-shaped with a round or oval nucleus and the neuronal cell profile areas were larger in the large intestine than in the small intestine. Most of the neurons display intense AChE activity in the cytoplasm. AChE-positive nerve fibers are present in a primary meshwork of large nerve bundles and in a secondary meshwork of finer nerve bundles. At the ultrastructural level, the ganglia are irregular in shape and covered with fibroblastlike cells. The nucleoplasm of the neurons is finely granular with a few condensations of chromatin attached to the nuclear envelope. In the neuropil numerous varicosities filled with vesicles of different size and electron densities are seen. The pre-and post-synaptic membrane thickenings are asymmetric. Characteristic glial cells with oval nuclei and few organelles are numerous. These data provide a detailed description of this submucosal meshwork.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
