ABSTRACT
Prospective cohort study from Brazil to evaluate glaucoma treatment adherence using a medication event monitoring system (MEMS) device and correlate with glaucoma progression and loss to follow-up (LTF) after one year of follow up. We included primary open glaucoma (POAG) patients treated with at least one ocular hypotensive eye drop. MEMS devices was used to monitor adherence for 60 days and evaluate the percentage of doses prescribed taken within the 60-day period. We classified patients according to rates of adherence: low adherence (less than 75% from MEMS measurements) and high adherence (more than 75% from MEMS measurements). We applied a questionnaire to investigated self-reported behavior towards treatment behaviors (glaucoma treatment compliance assessment tool, GTCAT). We also correlated rates of treatment adherence with clinical, demographical variables and the occurrence of glaucoma progression or LTF after one year of observation. We included 110 POAG patients and found that 28.18% of them were considered low adherent. We identify several variables associated with poor adherence such as glaucoma progression, LTF, younger age, low educational and income levels, absence of health insurance, years of disease and peak intraocular pressure. Several constructs from the self-reported GTCAT were also correlated with the rates of treatment adherence. To date, this is the first study in Latin America to evaluate glaucoma treatment adherence with MEMS devices and correlate adherence rates with glaucoma progression and LTF. We found a low-adherence rate of 28.18% and several additional risk factors were statistically associated with poor adherence.

The complement system is a fundamental component of the host immune response. In addition to its effector activity against pathogens, it possesses functions such as opsonization and phagocytosis, removal of immune complexes and activation of the inflammatory process. The knowledge of the complement system is important in the investigation of numerous diseases that can be observed in cases of deficiencies in cascade proteins, their receptors, or regulatory proteins. Clinical and experimental evidence demonstrate the association between the complement system and several inflammatory conditions, as well as a greater susceptibility to infection among patients with complement system dysfunction. Thus, the purpose of this paper is to describe the three complement system pathways - the activation and effector mechanisms and their biochemical characteristics - and correlate them to certain clinical conditions.
ABSTRACT
A despeito dos avanços no tratamento e das campanhas de prevenção e de controle da malária nos distintos continentes nos quais a moléstia grassa, a entidade mórbida permanece com significativa relevância no mundo contemporâneo. O Plasmodium falciparum é o grande responsável pela malária grave, caracterizada por distúrbios em diferentes órgãos e sistemas, com possibilidade de evolução ao óbito. Embora incipientes, os estudos proteômicos na malária têm trazido boas perspectivas para melhor compreensão dos aspectos biológicos do Plasmodium, assim como dos mecanismos fisiopatológicos, diagnósticos, terapêuticos e profiláticos da enfermidade. Desse modo, o objetivo do presente artigo é apresentar uma breve revisão das aplicações da análise proteômica na malária por P. falciparum.
Despite advances in treatment and campaigns for prevention and control of malaria on the various continents where it is still rampant, this disease remains significantly relevant to the contemporary world. Plasmodium falciparum is the organism that is mainly responsible for severe malaria, which is characterized by disturbances in different organs and systems, with possibly fatal outcomes. Although incipient, proteomic studies of malaria have yielded favorable prospects for elucidating the biological aspects of Plasmodium as well as the pathophysiological, diagnostic, prophylactic, and therapeutic mechanisms of the disease. Thus, the aim of the present article is to present a brief review of the applications of proteomic analysis in P. falciparum malaria.
ABSTRACT
A resposta inflamatória sistêmica representa o evento patogênico central da sepse, subjazendo às manifestações clínicas e aos achados laboratoriais presentes nos enfermos. Inúmeras pesquisas têm demonstrado que os linfócitos T CD4+CD25+ - também conhecidos como células T reguladoras (Treg) - participam dos processos de desenvolvimento da sepse, em virtude de sua capacidade de suprimir a resposta imune. Com base nessas ideias, propôs-se, no presente artigo, a discussão do papel dos linfócitos Treg na sepse, com base na revisão da literatura com estratégia de busca definida (LILACS, PubMed e SciELO), tendo em vista duas abordagens principais: a participação dessas células nos processos de inflamação e imunidade, e as perspectivas de investigação fisiopatológica computacional da condição mórbida.
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.
