This paper aims to provide an update on the main aspects of sepsis, a very relevant health care issue. A number of hypotheses have been proposed to explain its origin, involving interactions between microorganisms and the innate immune system, inflammation/immune mediation and the coagulation system. The clinical features of sepsis are variable and depend on the primary site of infection. The identification of early signs and symptoms is crucial for starting therapeutic measures fundamentally based on volume resuscitation, antibiotic therapy, use of steroids, anticoagulant therapy, biologic viability maintenance interventions and nutritional support.

Malaria is one of the world's leading parasitic diseases and affects a considerably large number of people. Considering the epidemiological reach of Plasmodium falciparum, which is almost always responsible for the most severe cases of malaria, a discussion of the clinical features and therapeutic interventions is important. In the cases of patients with severe malaria, admission to an intensive care unit is mandatory to reduce complications. To have an impact on survival rates, treatment with antimalarial drugs and supportive measures should be initiated as quickly as possible. The aim of this article is to discuss the components of severe malaria, with an emphasis on its clinical features and treatment.

RESUMO Diante das atuais demandas sociais, tornou-se imprescindível para a educação médica a transição-Learning.-Medical Students.-Medical Education. ABSTRACT Given current social demands, it has become essential for medical education to break from the traditional model of biological reductionist and training based only at hospitals and redefine itself towards a holistic care (integrality). The construction of new training practices in health with the use of new outdoor scenarios, in partnership with (Unified National Health System -SUS), assumed a key role. In 2005 the Centro Universitário Serra dos Órgãos (Unifeso) incorporated into its curriculum the Problem-Based Learning and the insertion of medical undergraduates into Basic Health Units

The systemic inflammatory response represents the core pathogenic event of sepsis, underlying clinical manifestations and laboratory findings in patients. Numerous studies have shown that CD4+CD25+ T lymphocytes, also known as regulatory T lymphocytes (Treg), participate in the development of sepsis due to their ability to suppress the immune response. The present article discusses the role of Treg lymphocytes in sepsis based on a specific search strategy (Latin American and Caribbean Health Sciences / Literatura Latino-americana e do Caribe em Ciências da Saúde-LILACS, PubMed, and Scientific Electronic Library Online-SciELO) focusing on two main topics: the participation of Treg cells in inflammation and immunity as well as perspectives in the computational physiological investigation of sepsis.
