Antiphospholipid syndrome

A Síndrome do Anticorpo Antifosfolípide (SAF) foi descrita recentemente e está associada a episódios de trombose venosa e arterial recorrentes, abortamento de repetição e trombocitopenia e, menos freqüentemente, à anemia hemolítica auto-imune e a manifestações cutâneas, cardíacas e neurológicas. Nesta revisão, discutem-se a fisiopatologia, o quadro clínico, a classificação e o tratamento da SAF e se analisam sessenta e nove (69) casos atendidos em nosso serviço.The antiphosfolipide syndrome (APS) was recently described and is associated with arterial and venous thrombosis, repeated abortions, thrombocypoenia and, less frequently, with autoimmune hemolitic anemia and cutaneous, cardiac or neurologic manifestations. This review discusses pathophysiology, clinical presentation and treatment of APS and includes an analysis of 69 cases seen in our clinic

Efeitos de estimulantes vegetais na germinação do arroz (Oryza sativa L: cv. IAC - 165)

The objective of the present work was to study the effect of Triacontanol and Agrostemmin on rice seeds by evalluating germination, coleoptile and seedling root growing, under laboratory conditions. The Petri dishes received 10 ml of solution (ether and benzene) for Triacontanol treatments and distilled water for the Agrostemmin treatments. Results showed that the treatments does not present significant effects in relation to germination percent but a statistically significant effect with respect to seedling root growing was observed.O presente trabalho teve como objetivo estudar o efeito de Triacontanol e Agrostemin em sementes de arroz, através da avaliação da germinação, do crescimento de coleóptiles e raízes das plântulas, em condições de laboratório. As placas de Petri receberam 10 ml de solução (éter e benzeno) correspondente aos tratamentos com Triacontanol, enquanto as dosagens de Agrostemin foram aplicadas em solução de água destilada. Verificou-se que nenhum dos tratamentos mostraram efeitos significativos sobre a porcentagem de germinação, mas provocaram um crescimento diferencial estatisticamente significativo em relação as radículas

Cross-cultural adaptation of the City Birth Trauma Scale for the Brazilian context

Background: Posttraumatic stress disorder consists of a set of symptoms that occurs in response to one or more traumatic events and can occur in postpartum, from traumatic situations related to the birth or to the baby’s health in the first days of life. It is important tracking the presence of birth trauma, but there is not available instruments in the Brazilian context for this purpose. Objectives: To present the cross-cultural adaptation of City Birth Trauma Scale (BiTS) into Brazilian portuguese. Methods: Cross-cultural adaptation involved independent translations, synthesis,back-translation, and submission to the original author’s appreciation. After the scale was subjected to face validity, followed by a pilot study with postpartum mothers. Results: All steps were performed for the cross-cultural adaptation. Regarding face validity, items evaluated concerning different types of equivalence, presented satisfactory agreement values (≥4.20). Most of the expert’s suggestions were followed, being the main ones related to adjustments in prepositions, pronouns and verbal subjects. Pilot study showed that the mothers had been able to understand and respond to the instrument without adjustments. Discussion: BiTS’s Brazilian version proved to be cross-culturally adapted, ensuring the possibility of intercultural data comparison from the semantic, idiomatic, cultural, and conceptual perspectives. New studies are being conducted to attest its psychometric adequac

Prevalência e tendências temporais de transtornos mentais necessitando de tratamento de internação na cidade de Porto Alegre: Um estudo de toda a cidade incluindo todas as internações por motivo de saúde mental no sistema público de 2013-2017

Objectives: To investigate the 5-year prevalence of patients admitted to public inpatient care units due to a mental disorder, stratifying them by age group and diagnosis, and to assess trends of admissions over this time period in Porto Alegre. Methods: All admissions to the public mental health care system regulated by the city-owned electronic system Administração Geral dos Hospitais (AGHOS) were included in the analysis. The total population size was obtained by estimations of Fundação de Economia e Estatística (FEE). General information about 5-year prevalence of inpatient admissions, time-series trends e prevalence by age groups and diagnosis were presented. Results: There were 32,608 admissions over the 5-year period analyzed. The overall prevalence of patients was 1.62% among the total population, 0.01% among children, 1.12% among adolescents, 2.28% among adults and 0.93% among the elderly. The most common diagnosis was drug-related, followed by mood, alcohol-related and psychotic disorders. There was a linear trend showing an increase in the number of admissions from 2013 to the midst of 2014, which dropped in 2015. Conclusions: Admissions due to mental disorders are relatively common, mainly among adults and related to drug use and mood disorders. Time trends varied slightly over the 5 years. Prevalence rates in real-world settings might be useful for policymakers interested in planning the public mental health system in large Brazilian cities

A Recombinant Protein Based on Trypanosoma cruzi P21 Enhances Phagocytosis

Background: P21 is a secreted protein expressed in all developmental stages of Trypanosoma cruzi. The aim of this study was to determine the effect of the recombinant protein based on P21 (P21-His(6)) on inflammatory macrophages during phagocytosis. Findings: Our results showed that P21-His(6) acts as a phagocytosis inducer by binding to CXCR4 chemokine receptor and activating actin polymerization in a way dependent on the PI3-kinase signaling pathway. Conclusions: Thus, our results shed light on the notion that native P21 is a component related to T. cruzi evasion from the immune response and that CXCR4 may be involved in phagocytosis. P21-His(6) represents an important experimental control tool to study phagocytosis signaling pathways of different intracellular parasites and particles.Fundacao de Amparo a Pesquisa do Estado de Minas Gerais [APQ-00621-11]Fundacao de Amparo a Pesquisa do Estado de Minas GeraisFundacao de Amparo a Pesquisa do Estado de Sao PauloFundacao de Amparo a Pesquisa do Estado de Sao PauloCoordenacao de Aperfeicoamento de Pessoal de Nivel Superior [23038005295/2011-40]Coordenacao de Aperfeicoamento de Pessoal de Nivel SuperiorConselho Nacional de Desenvolvimento Cientifico e TecnologicoConselho Nacional de Desenvolvimento Cientifico e Tecnologic
