Abstract
BACKGROUND Men who have sex with men in Brazil are deferred from donation for 1 year since their last sexual contact. Legal proceedings in front of the Brazilian Supreme Court could compel blood collection agencies to discontinue use of sexual orientation questions. METHODS Data from male participants in a completed HIV risk factor case-control study were used to evaluate whether it is possible to differentiate donors at lower and higher risk for HIV using two analytical approaches: latent class and random forest analyses. RESULTS Male blood donors were divided into three distinct risk profile classes. Class 1 includes donors who are heterosexual (96.4%), are HIV negative (88.7%), have a main partner (99.4%), and practice unprotected sex (77.8%). Class 2 includes donors who are men who have sex with men /bisexuals' (100.0%), are HIV positive (97.4%), and were not aware of their sexual partners' HIV status (80.3%). Class 3 includes donors who are heterosexual (84.1%), practice unprotected vaginal/anal heterosexual sex (66.8% vs. 40.9%), and were both HIV positive and HIV negative (49.5% vs. 50.5%). We also found that asking donors about their partner(s)' HIV serostatus could replace asking about donors' sexual orientation and types of partners with relatively minor shifts in sensitivity (0.76 vs. 0.58), specificity (0.89 vs. 0.94), and positive predictive value (0.85 vs. 0.88). CONCLUSION Sexual orientation questions on the donor questionnaire could be replaced without great loss in the sensitivity, specificity, and positive predictive value. Social and sexual behaviors of donors and their partners are proxies for HIV risk and can help to develop modified questions that will need controlled trials to be validated.

Abstract
BACKGROUND Vestibular-evoked myogenic potential triggered by galvanic vestibular stimulation (galvanic-VEMP) evaluates the motor spinal cord and identifies subclinical myelopathies. We used galvanic-VEMP to compare spinal cord function in individuals infected with human T-cell lymphotropic virus type 1 (HTLV-1) from asymptomatic status to HTLV-1-associated myelopathy (HAM). METHODOLOGY/PRINCIPAL FINDINGS This cross-sectional study with 122 individuals included 26 HTLV-1-asymptomatic carriers, 26 individuals with possible HAM, 25 individuals with HAM, and 45 HTLV-1-seronegative individuals (controls). The groups were similar regarding gender, age, and height. Galvanic stimuli (duration: 400 ms; intensity: 2 mA) were applied bilaterally to the mastoid processes and VEMP was recorded from the gastrocnemius muscle. The electromyographic parameters investigated were the latency and amplitude of the short-latency (SL) and medium-latency (ML) responses. While SL and ML amplitudes were similar between groups, SL and ML latencies were delayed in the HTLV-1 groups compared to the control group (p<0.001). Using neurological examination as the gold standard, ROC curve showed an area under the curve of 0.83 (p<0.001) for SL and 0.86 (p<0.001) for ML to detect spinal cord injury. Sensibility and specificity were, respectively, 76% and 86% for SL and 79% and 85% for ML. Galvanic-VEMP disclosed alterations that were progressive in HTLV-1-neurological disease, ranging from SL delayed latency in HTLV-1-asymptomatic carriers, SL and ML delayed latency in possible HAM group, to absence of VEMP response in HAM group. CONCLUSIONS/SIGNIFICANCE The worse the galvanic-VEMP response, the more severe the myelopathy. Galvanic-VEMP alteration followed a pattern of alteration and may be a prognostic marker of progression from HTLV-1-asymptomatic carrier to HAM.

Abstract
A relevant issue in Chagas disease serological diagnosis regards the requirement of using several confirmatory methods to elucidate the status of non-negative results from blood bank screening. The development of a single reliable method may potentially contribute to distinguish true and false positive results. Our aim was to evaluate the performance of the multiplexed flow-cytometry anti-T. cruzi/Leishmania IgG1 serology/(FC-TRIPLEX Chagas/Leish IgG1) with three conventional confirmatory criteria (ELISA-EIA, Immunofluorescence assay-IIF and EIA/IIF consensus criterion) to define the final status of samples with actual/previous non-negative results during anti-T. cruzi ELISA-screening in blood banks. Apart from inconclusive results, the FC-TRIPLEX presented a weak agreement index with EIA, while a strong agreement was observed when either IIF or EIA/IIF consensus criteria were applied. Discriminant analysis and Spearman's correlation further corroborates the agreement scores. ROC curve analysis showed that FC-TRIPLEX performance indexes were higher when IIF and EIA/IIF consensus were used as a confirmatory criterion. Logistic regression analysis further demonstrated that the probability of FC-TRIPLEX to yield positive results was higher for inconclusive results from IIF and EIA/IIF consensus. Machine learning tools illustrated the high level of categorical agreement between FC-TRIPLEX versus IIF or EIA/IIF consensus. Together, these findings demonstrated the usefulness of FC-TRIPLEX as a tool to elucidate the status of non-negative results in blood bank screening of Chagas disease.

Abstract
Differential serological diagnosis of Chagas disease and leishmaniasis is difficult owing to cross-reactivity resulting from the fact that the parasites that cause these pathologies share antigenic epitopes. Even with optimized serological assays that use parasite-specific recombinant antigens, inconclusive test results continue to be a problem. Therefore, new serological tests with high sensitivity and specificity are needed. In the present work, we developed and evaluated the performance of a new flow cytometric serological method, referred to as FC-TRIPLEX Chagas/Leish IgG1, for the all-in-one classification of inconclusive tests. The method uses antigens for the detection of visceral leishmaniasis, localized cutaneous leishmaniasis, and Chagas disease and is based on an inverted detuned algorithm for analysis of anti-Trypanosomatidae IgG1 reactivity. First, parasites were label with fluorescein isothiocyanate or Alexa Fluor 647 at various concentrations. Then serum samples were serially diluted, the dilutions were incubated with suspensions of mixed labeled parasites, and flow cytometric measurements were performed to determine percentages of positive fluorescent parasites. Using the new method, we obtained correct results for 76 of 80 analyzed serum samples (95% overall performance), underscoring the outstanding performance of the method. Moreover, we found that the fluorescently labeled parasite suspensions were stable during storage at room temperature, 4 °C, and -20 °C for 1 year. In addition, two different lots of parasite suspensions showed equivalent antigen recognition; that is, the two lots showed equivalent categorical segregation of anti-Trypanosomatidae IgG1 reactivity at selected serum dilutions. In conclusion, we have developed a sensitive and selective method for differential diagnosis of Chagas disease, visceral leishmaniasis, and localized cutaneous leishmaniasis.

Abstract
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 services 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
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
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.

Abstract
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
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.

Abstract
Dermatologic manifestations are quite common in patients with adult T cell leukemia/lymphoma and myelopathy/tropical spastic paraparesis associated with infection with human T cell lymphotropic virus type-1 (HTLV-1). In this study, we evaluated the dermatologic lesions of eligible blood donors in the state of Minas Gerais in Brazil who were seropositive but asymptomatic for infection with HTLV-1. The study population was composed of 128 HTLV-1-seropositive individuals and 108 seronegative controls. All individuals underwent a dermatologic evaluation. Biopsy specimens were obtained from abnormal and normal skin samples of seropositive individuals in an attempt to detect HTLV-1 in tissue samples by a polymerase chain reaction. Dermatologic alterations were observed more frequently in the seropositive group (adjusted odds ratio [OR] = 8.77, 95% confidence interval [CI] = 4.11-18.71). The most common skin diseases were dermatophytoses (adjusted OR = 3.32, 95% CI = 1.50-7.35), seborrheic dermatitis (OR = 3.53, 95% CI = 0.67-24.66), and acquired ichthyosis (P = 0.001). Virus was detected more frequently in abnormal skin samples. Dermatologic lesions probably related to HTLV-1 infection were diagnosed in eligible blood donors who were infected with this virus, who were previously considered to be asymptomatic carriers of HTLV-1.

Abstract
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.
