The current curricula in medical schools and hospital residence worldwide lack exposure to blood transfusion medicine, and require the reformulation of academic programs. In many countries, training in blood transfusion is not currently offered to medical students or during residency. Clinical evidence indicates that blood transfusions occur more frequently than recommended, contributing to increased risk due to this procedure. Therefore, the rational use of blood and its components is essential, due to the frequent undesirable reactions, to the increasing demand of blood products and the cost of the process. Signiﬁcant improvements in knowledge of and skills in transfusion medicine are needed by both students and residents. Improvements are needed in both background knowledge and the practical application of this knowledge to improve safety. Studies prove that hemovigilance has an impact on transfusion safety and helps to prevent the occurrence of transfusion-related adverse effects. To ensure that all these aspects of blood transfusion are being properly addressed, many countries have instituted hospital transfusion committees. From this perspective, the interventions performed during the formation of medical students and residents, even the simplest, have proven effective in the acquisition of knowledge and medical training, thereby leading to a reduction in inappropriate use of blood. Therefore, we would like to emphasize the importance of the exposure of medical students and residents to blood ser- vices and transfusion medicine in order for them to acquire adequate medical training, as well as to discuss some changes in the current medical curricula regarding transfusion medicine that we judge critical.

Abstract: En | Text: En | PDF: En

OBJECTIVE Sickle cell disease comprises chronic, genetically determined disorders, presenting significant morbidity and high prevalence in Brazil. The goal of this study was to evaluate the quality of life of sickle cell disease patients (hemoglobin SS and SC) and their sociodemographic and clinical characteristics. METHODS Data was collected from clinical records and semi-structured interviews consisting of clinical questionnaires and the World Health Organization Quality of Life-brief questionnaire. RESULTS Interviews were conducted with 400 patients, aged between 18 and 72, treated in the Fundação HEMOMINAS in Belo Horizonte. The participants predominantly had sickle cell disease hemoglobin SS variant (65.5%), were female (61.8%), single (55.3), with up to 8 years of schooling (49.6%), and self-defined as mulattos (50%). Pain crises, hospitalizations, blood transfusions, and other morbidities of sickle cell disease had a significant impact on the quality of life of these patients. CONCLUSION Within this group, the social profile was that of low income and unemployed with sickle cell disease considered to be a significant impediment to finding a job. Evaluating quality of life as a determining factor of health is essential for the creation of specific policies and measures, appropriate for the specific characteristics and social context of sickle cell disease.

Abstract: En | Text: En | PDF: En

BACKGROUND: Seasonal distribution of blood donation hinders efforts to provide a safe and adequate blood supply leading to chronic and persistent shortages. This study examined whether holidays, geographical area and donation type (community versus replacement) has any impact on the fluctuation of donations. METHODS: The numbers of blood donations from 2007 through 2010 in three Brazilian Retrovirus Epidemiological Donor Study II (REDS-II) participating centers were analyzed according to the week of donation. The weeks were classified as holiday or non-holiday. To compare donations performed during holiday versus non-holiday weeks, tabulations and descriptive statistics for weekly donations by blood center were examined and time series analysis was conducted. RESULTS: The average weekly number of donations varied according to the blood center and type of week. The average number of donations decreased significantly during Carnival and Christmas and increased during the Brazilian National Donor Week. The fluctuation was more pronounced in Recife and Belo Horizonte when compared to São Paulo and higher among community donors. CONCLUSION: National bank holidays affect the blood supply by reducing available blood donations. Blood banks should take into account these oscillations in order to plan local campaigns, aiming at maintaining the blood supply at acceptable levels.

Este estudo teve como objetivo descrever a distribuição espacial e temporal dos candidatos à doação de sangue, do Município de Belo Horizonte, Minas Gerais, Brasil, que se apresentaram no hemocentro da Fundação Hemominas, nos anos de 1994 e 2004. Comparou no espaço e no espaço-tempo as características idade, sexo e aptidão clínica destes candidatos. As informações de 1994, obtidas de estudo transversal, e as de 2004, amostrados entre os candidatos à doação durante o ano. As amostras foram georreferenciadas através dos endereços de residência. As técnicas espaciais utilizadas foram: mapas Kernel, mapas temáticos de taxas Bayesianas empíricas e de taxas brutas e o índice de Moran global. Os resultados indicaram que a distribuição espacial de candidatos não foi aleatória. Os mapas Kernel auxiliaram na detecção de locais com maior ou menor concentração de candidatos. Os mapas temáticos descreveram a concentração de candidatos relativos à população para as diferentes categorias analisadas. Estes resultados ajudam na detecção de locais para ações direcionadas à captação de candidatos à doação bem como locais com necessidades de campanhas a públicos específicos.

The main goal of this study was to describe the spatial and temporal distribution of candidates for blood donation in Belo Horizonte, Minas Gerais State, Brazil, who appeared at the Hemominas Foundation in 1994 and 2004. The study also compared the candidates for age, gender, and clinical approval for blood donation in space and space-time. Data were obtained from a cross-sectional study for 1994 and were randomly selected from all donor candidates for 2004. The samples were georeferenced using the residential address. The spatial analysis techniques employed were: Kernel maps, thematic maps of Bayesian empirical rates and crude rates, and Moran Global. According to the findings, spatial distribution of candidates was non-random. The Kernel maps helped detect points with higher or lower concentration of candidates. Thematic maps described the concentration of candidates in relation to the population for the various categories. The results could help detect areas for actions targeting donor recruitment and areas with specific blood donation public campaign needs.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

A infecção pelo vírus linfotrópico de células T humanas (HTLV) ocorre há milhares de anos. No entanto, o conhecimento sobre a sua patogênese é recente. Esse vírus é endêmico em várias regiões do mundo. No Brasil encontra-se presente em todos os estados, com prevalências variadas, sendo estimado cerca de 2,5 milhões de infectados. Fatores genéticos e imunológicos do hospedeiro são os principais responsáveis pelas manifestações clínicas associadas, que podem ser divididas em três categorias: neoplásicas, inflamatórias e infecciosas. Destacam-se a mielopatia associada ao HTLV (HAM/TSP) e a leucemia/linfoma de células T do adulto (ATLL) como as primeiras doenças associadas a esse retrovírus. Posteriormente, inúmeras outras doenças têm sido correlacionadas a esse vírus. Esta revisão atualiza conhecimentos epidemiológicos, fisiopatológicos, terapêuticos e principalmente diagnósticos do HTLV. O objetivo é permitir a suspeita etiológica do HTLV em suas diversas manifestações clínicas, hoje pouco correlacionadas com este agente.

Human T Lymphotropic Virus (HTLV) infection has occurred for thousands of years. However, knowledge about this pathogenesis is recent. This virus is endemic worldwide. In Brazil it is present throughout the country , with different prevalence and about 2 5 million infected. Genetic and immunologic characteristics of the host are chiefly responsible for clinically associated manifestations which may be: neoplasic, inflammatory and infectious diseases. HTLV associated myelopathy (TSP/ HAM) and adult T cell leukemia/lymphoma (ATL) stand out as the first diseases associated to this retrovirus. Further, several diseases have been correlated to this virus. This review updates epidemiologic, physiopathologic, therapeutic and diagnostic knowledge of HTLV. The purose is to orient suspicion of HTLV etiology and several clinically associated manifestations, which currenty are seldom correlated with this virus.

OBJETIVO: A associação entre depressão e viroses é estudada há quase dois séculos, com resultados conflitantes. O objetivo deste trabalho é fazer uma análise crítica dos estudos existentes na literatura sobre essa relação. MÉTODOS: A pesquisa bibliográfica utilizou as fontes eletrônicas de busca MEDLINE e LILACS (1966 a agosto 2005). As referências dos artigos foram utilizadas como fonte adicional de consulta. RESULTADOS: Foram abordados os trabalhos que trataram da associação entre depressão e os vírus HIV, HCV, EBV, influenza, HSV, HBV, HAV, BDV e HTLV. A relação entre HIV e depressão mostrou-se bem documentada na literatura. Existem indícios de que a prevalência desse transtorno nos indivíduos infectados pelo HIV seja maior que a encontrada nos soronegativos. Além disso, estudos constataram que a depressão está associada a pior prognóstico da infecção. Quanto à associação entre HCV e depressão, os trabalhos sugeriram maior prevalência desse transtorno psiquiátrico nos portadores do HCV comparados à população geral. Não existem evidências científicas suficientes para dar suporte à relação entre os demais vírus e depressão. CONCLUSÃO: As associações mais bem fundamentadas foram aquelas entre depressão e os vírus HIV e HCV. A relação entre as demais viroses e depressão precisa ser mais bem estudada, e trabalhos com delineamento adequado se fazem necessários.

OBJECTIVE: The association between depression and viruses has been evaluated for almost two centuries now, with conflicting results. The objective of the present study is to perform a critical review of published studies in the literature about this relationship. METHODS: Databases MEDLINE and LILACS were searched between 1966 and 2005 (until August). The references of the articles were used as additional source of data. RESULTS: Studies about the link between depression and infection with viruses HIV, HCV, EBV, influenza, HSV, HBV, HAV, BDV and HTLV were analyzed. The association between HIV and depression was well documented in literature. There are evidences that the prevalence of this disorder in HIV-infected individuals is greater than that found in seronegatives. Moreover, studies concluded that depression is associated with a worse course of infection. Regarding the link between HCV and depression, studies suggested a greater prevalence of this psychiatric disorder in HCV-infected people compared with general population. There is not enough scientific evidence to support the association between other viruses and depression. CONCLUSION: The best-studied relationships were those between depression and viruses HIV and HCV. Regarding the association of other viruses with depression, more research is needed.

Relatamos resultados do estudo de seqüência de nucleotídeos e análise filogenética do gene env 11 isolados HIV-1 em Belo Horizonte, Brasil. Dez isolados pertenciam ao subtipo B e um era provavelmente um mosaico B/F. Este possível recombinante B/F é similar, mas não idêntico, em sua seqüência de nucleotídeos, aos demais mosaicos B/F descritos no Brasil.

We report results of nucleotide sequencing and phylogenetic analysis of the env gene of 11 HIV-1 isolates, in Belo Horizonte, Brazil. Ten isolates belonged to HIV-1 subtype B and one was a probable B/F mosaic. This putative B/F recombinant is similar but not identical in its nucleotide sequence to other B/F mosaics described in Brazil.
