Background: Blood transfusion is an effective therapeutic practice. However, even adopting all procedures for transfusion safety, there are risks, one of which is immediate adverse reactions. The aim of this study was, by active search, to evaluate the occurrence of immediate adverse reactions estimating the occurrence rate within the first 24 h. Methods: An exploratory, descriptive, prospective study with quantitative analysis was carried out of patients undergoing surgery who received blood component transfusions during hospitalization from October 2018 to August 2019. Data on blood component request forms were collected from the transfusion agency by reviewing medical records and interviewing the patient or family members. Descriptive statistics and the chi-square test were used to analyze the association of demographic variables with the presence or absence of transfusion reactions. Results: A total of 1042 blood component units were transfused in 393 transfusions performed on 184 patients. The main transfused blood component was packed red blood cells. Seventeen reactions were identified in the medical records, using the active search method, none of which had been reported. The transfusion reaction rate was 16.3 occurrences per 1000 transfused units, while the notification rate for the 9389 blood component units transfused by the transfusion agency in the study period was 3.83/1000. There was no statistically significant association between the occurrences or not of transfusion reactions and demographic variables. Conclusion: Through the active search method, it was possible to observe the underreporting of adverse reactions, showing inadequate compliance with current legislation, which is essential to minimize errors and increase transfusion safety.

A doença de Chagas crônica afeta seis milhões de pessoas em regiões endêmicas, com 30 mil novos casos anuais – logo, espaços de divulgação científica são muito importantes para ofertar informações de qualidade à população. As iniciativas envolvendo o controle da doença de Chagas não podem se limitar às pesquisas com enfoque biológico. Este estudo objetiva apresentar um panorama sobre o processo de construção do canal Falamos de Chagas, no YouTube, sua importância para a comunicação, a informação, a educação em saúde e a mobilização social, bem como refletir sobre a qualidade de uma subamostra de vídeos do canal. Trata-se de um estudo qualitativo, dividido em duas fases: criação do canal e análise qualitativa dos vídeos sobre a doença disponíveis no YouTube. Observamos que existe potencial nas redes sociais, enquanto recurso de comunicação, contudo é preciso cautela, uma vez que se faz necessária a certificação da qualidade do material.

Abstract Background Sickle cell disease (SCD) is an autosomal recessive genetic disease in which a mutation occurs in the β-globin chain gene, resulting in abnormal hemoglobin levels. In an environment with reduced oxygen concentration, red blood cells change their conformation, resulting in chronic hemolysis and consequent anemia and vaso-occlusive crises with injuries to several organs, with a significant impairment of the osteoarticular system. This study aimed to verify the chronic osteoarticular alterations and their association with clinical and laboratory characteristics of patients with SCD with a more severe phenotype (SS and Sβ0), on a steady-state fasis. Methods Fifty-five patients were referred to a medical consultation with a specialized assessment of the locomotor system, followed by laboratory tests and radiographic examinations. Results In total, 74.5% patients had hemoglobinopathy SS; 67.3% were female; and 78.2% were non-whites. The mean patient age was 30.5 years. Most patients (61.8%) reported up to three crises per year, with a predominance of high-intensity pain (65.5%). Radiographic alterations were present in 80% patients. A total of 140 lesions were identified, most which were located in the spine, femur, and shoulders. Most lesions were osteonecrosis and osteoarthritis and were statistically associated with the non-use of hydroxyurea. Conclusions There was a high prevalence of chronic osteoarticular alterations, which was statistically associated only with the non-regular use of hydroxyurea.

Abstract Sickle cell intrahepatic cholestasis is a potentially fatal syndrome characterized by jaundice, painful hepatomegaly, and organ dysfunction. Two cases of sickle cell intrahepatic cholestasis associated with dengue fever were described. Endothelial damage/dysfunction is a mechanism involved in severe hepatobiliary complications related to sickle cell diseases. However, the reasons for the lack of increase in the admission of patients with sickle cell disease having severe acute hepatobiliary complications triggered by endothelial damage/dysfunction due to dengue fever remain unknown. This study describes the first association between sickle cell intrahepatic cholestasis and dengue fever.

Background: The selection of compatible human leukocyte antigen platelets has been associated with improved platelet increments. Therefore, an effective strategy would be the selection of donors who are genetically compatible according to the human leukocyte antigen system. Nonetheless, this is costly as it concerns a highly polymorphic system, which requires a large bank of genotyped donors. Methods: This study evaluated the feasibility of virtual crossmatching using EpVix software, which simplifies the identification of compatible donors or donors with acceptable incompatibilities. Results: Forty-three oncohematological patients were evaluated, in 96 platelet transfusion episodes with 16.3% of the patients being found to be refractory to platelet transfusions. Eight alloimmunized, multitransfused patients were selected to evaluate human leukocyte antigen compatibility against a bank of 336 platelet donors. At least partially compatible donors were found for all patients. The number of compatible donors was found to be inversely proportional to the human leukocyte antigen-panel reactive antibody score of each patient. It was noted that five patients with scores of 15% or less had at least 190 compatible donors; four fully compatible donors were found for two other patients with scores greater than 80% and only one patient (score of 93%) did not have a fully compatible donor. However, for this last patient, 40 donors were partially compatible according to the software. Conclusion: The results showed the effectiveness of the use of the EpVix tool to identify potential platelet donors for multitransfused and/or alloimmunized patients, even with a small number of human leukocyte antigen genotyped donors available. Keywords: Platelet transfusion, HLA antigens, Crossmatching, EpVix software

Tuberculose, dengue, zika, chikungunya e febre amarela são doenças que se apresentam como um grande desafio para a saúde pública e demandam participação popular para o seu controle, o que consiste em um ponto nevrálgico contemporâneo. A convergência dos campos da Ciência e da Arte (CienciArte) proporciona a ampliação dos horizontes de percepção da leitura do mundo e uma interpretação multifacetada na busca para a resolução criativa de questões sociais. Realizamos oficinas de CienciArtevisando a produção de animações do tipo stop motion para a formação de multiplicadores para o controle de agravos e promoção da saúde. A análise das imagens produzidas pelos participantes e do seu processo educativo evidenciou que a proposta estimulou o trabalho em grupo, sensibilizou os integrantes das oficinas para a participação social e a elaboração de estratégias que dialoguem com a população de forma mais próxima. O processo criativo proporcionado aguçou a escuta e o olhar ampliado para o tema de interesse. Mas as produções visuais desenvolvidas pelos participantes das oficinas ainda guardam fragmentos de processos educativos e comunicacionais de estratégias padronizadas e tradicionais que desafiam as estratégias mais inovadoras.

Level B and D practices were executed, such as oxytocin 236 (63.3%), amniotomy 171 (45.8%), episiotomy 51 (19.8%) and Kristeller’s 129 (34.6%). Conclusion: this study reveals the need to adapt the ambience and implement the best practices unrestrictedly in order to guarantee safe delivery and birth care and to contribute to the training of new professionals.

Irradiation of blood components with ionizing radiation generated by a specific device is recommended to prevent transfusion-associated graft-versus-host disease. However, a lin- ear accelerator can also be used in the absence of such a device, which is the case of the blood bank facility studied herein. In order to evaluate the quality of the irradiated packed red blood cells, this study aimed to determine whether the procedure currently employed in the facility is effective in inhibiting the proliferation of T lymphocytes without damaging blood components. The proliferation of T lymphocytes, plasma potassium levels, and the degree of hemolysis were evaluated and compared to blood bags that received no irradiation. Packed red blood cell bags were irradiated at a dose of 25 Gy in a linear accelerator. For this purpose, a container was designed to hold the bags and to ensure even distribution of irradiation as evaluated by computed tomography and dose-volume histogram. Irradiation was observed to inhibit the proliferation of lymphocytes. The percentage of hemolysis in irradiated bags was slightly higher than in non-irradiated bags (p-value >0.05), but it was always less than 0.4% of the red cell mass. Although potassium increased in both groups, it was more pronounced in irradiated red blood cells, especially after seven days of storage, with a linear increase over storage time. The findings showed that, at an appropriate dosage and under validated conditions, the irradiation of packed red blood cells in a linear accelerator is effective, inhibiting lymphocyte proliferation but without compromising the viability of the red cells.

A dengue constitui grave problema de saúde púbica no mundo. Objetivou-se analisar impressos sobre dengue circulantes numa área endêmica do Rio de Janeiro e as opiniões de profissionais de saúde e de educação sobre o uso dos mesmos. Analisou-se 17 materiais impressos com base nos critérios de estrutura e formatação, conteúdo, linguagem e ilustrações, a partir de perspectiva pedagógica construtivista. Além disso, entrevistou-se 16 profissionais de saúde e sete docentes de Ciências e Biologia. As falas foram submetidas à análise de conteúdo por unidades temáticas. Os impressos possuem boa qualidade gráfica e linguagem inteligível, porém há conceitos científicos simplificados e abordagem pedagógica tradicional. Há discurso prescritivo em relação às ações de controle e ausência de informações sobre etiologia, sintomatologia, tratamento da doença e seus determinantes sociais. Os entrevistados reportam a necessidade de inclusão de tópicos relacionados à epidemiologia e maior contextualização do conteúdo com a realidade local.

Background: Hemovigilance is an organized system of surveillance throughout the transfusion chain intended to evaluate information in order to prevent the appearance or recurrence of adverse reactions related to the use of blood products. Objective: The aims of this study were to assess the late reporting of incidents related to possible seroconversion in respect to age, marital status and ethnical background, annual variations in late reporting, the number of reports opened and closed, seroconversion of donors and transfusions of blood products within the window period. Methods: This retrospective, descriptive study used data on blood donations in the blood bank in Uberaba during the period from 2004 to 2011. Some socio-epidemiological characteristics of the donors and serology test results of donors and recipients were analyzed in respect to the late reporting of incidents related to possible seroconversion. The Chi-square test, odds ratio and a regression model were used for statistical analysis. Results: From 2004 to 2011, the blood bank in Uberaba collected 117,857 blood bags, 284 (0.24%) of which were investigated for late reported incidents. The profile of the donors was less than 29 years old, unmarried and non-Whites. Differences in age (p-value < 0.0001), marital status (p-value = 0.0002) and ethnical background (p-value < 0.0001) were found to be statistically significant. There was no statistical difference between men and women (0.24% and 0.23% respectively; p-value = 0.951). The number of late reported incidents increased until 2008 followed by a downward trend until 2011. There were twelve cases of seroconversion in subsequent donations (seven human immunodeficiency virus, four hepatitis B and one hepatitis C) with proven human immunodeficiency virus infection after screening of only one recipient. Conclusion: The twelve cases of seroconversion in donors with subsequent infection proven in one recipient underscores the importance of this tool to increase transfusion safety.

A dengue constitui um grave problema de saúde pública no Brasil. As Diretrizes Nacionais de Prevenção e Controle das Epidemias de Dengue preconizam que ações de educação em saúde associadas ao tema dengue sejam contempladas, no espaço escolar, na grade curricular das disciplinas. No ensino formal, o livro didático se caracteriza como um dos principais recursos para a prática docente e disseminação de conhecimentos científicos. Assim, analisou-se a temática da dengue nos livros didáticos de ciências e biologia, indicados pelos Programa Nacional do Livro Didático para o Ensino Médio (PNLEM/2009) e Programa Nacional do Livro Didático (PNLD/2008 e 2011), respectivamente. O tema esteve presente em quarenta livros didáticos dos 114 indicados pelo PNLD (2008 e 2011) e PNLEM (2009). Verificaram-se erros conceituais, emprego de ilustrações inadequadas e descontextualização sociocultural do conteúdo. Estes fatores limitam a utilização deste instrumento colaborativo para as ações desencadeadas no ambiente escolar com vistas ao controle da dengue.

Among the major health problems which have affected the Brazilian population is dengue, requiring integrated and participatory control actions. The study investigated the existence or no of intersectoral actions between health and education areas in an endemic region of Rio de Janeiro state. To such were conducted semi-structured interviews with seven teachers of science and biology of a public school and 16 health professionals from a health care unit close the school selected. The interviews were analyzed by thematic content. The results showed superficial knowledge about the disease, lacking dialogue between the protagonists of the sectors investigated and the informational materials available are scarce and sometimes inadequate.

BACKGROUND: Several irregular red blood cell alloantibodies, produced by alloimmunization of antigens in transfusions or pregnancies, have clinical importance because they cause hemolysis in the fetus and newborn and in transfused patients. OBJECTIVE: a prospective analysis of patients treated by the surgical and clinical emergency services of Hospital de Clínicas of the Universidade Federal do Triângulo Mineiro (HC/UFTM), Brazil was performed to correlate alloimmunization to clinical and epidemiological data. METHODS: Blood samples of 143 patients with initial negative antibody screening were collected at intervals for up to 15 months after the transfusion of packed red blood cells. Samples were submitted to irregular antibody testing and, when positive, to the identification and serial titration of alloantibodies. The Fisher Exact test and Odds Ratio were employed to compare proportions. RESULTS: Fifteen (10.49%) patients produced antibodies within six months of transfusion. However, for 60% of these individuals, the titers decreased and disappeared by 15 months after transfusion. Anti-K antibodies and alloantibodies against antigens of the Rh system were the most common; the highest titer was 1:32 (anti-K). There was an evident correlation with the number of transfusions. CONCLUSIONS: Given the high incidence of clinically important red blood cell alloantibodies in patients transfused in surgical and clinical emergency services, we suggest that phenotyping and pre-transfusion compatibilization for C, c, E, e (Rh system) and K (Kell system) antigens should be extended to all patients with programmed surgeries or acute clinical events that do not need emergency transfusions.OBJETIVO: Vários aloanticorpos irregulares antieritrocitários, produzidos por sensibilizações a antígenos estranhos durante gestações ou transfusões, possuem importância clínica por provocarem hemólise no feto ou recém-nascido e/ou no receptor de sangue. Diante disso, fizemos uma análise prospectiva exclusiva de pacientes atendidos nos serviços de emergência clínica e cirúrgica, correlacionando as aloimunizações aos dados clínicos e epidemiológicos. MÉTODOS: Amostras sanguíneas de 143 pacientes, com pesquisa inicial de anticorpos negativa, foram coletadas até 15 meses após transfusões de concentrados de hemácias (CH), submetidas a Pesquisas de Anticorpos Irregulares (PAI) e, quando o resultado fosse positivo, à identificação e titulação seriada do(s) aloanticorpo(s). Para comparar proporções, foi empregado Teste Exato de Fisher e Odds Ratio. RESULTADOS: Dos pacientes estudados, 15 (10,49%) produziram aloanticorpos em um período de seis meses, com o título decaindo e negativando até 15 meses em 60% dos aloimunizados. Os aloanticorpos anti-K e os dirigidos contra antígenos do sistema Rh foram os mais frequente, o maior título foi de 1:32 (anti-K) e houve evidente correlação com o número de transfusões. CONCLUSÃO: Diante da alta ocorrência de aloanticorpos antieritrocitários de importância clínica em indivíduos transfundidos em serviço de emergência clínica e cirúrgica, propomos estender a fenotipagem e compatibilização pré-transfusional para os antígenos C, c, E, e (sistema Rh) e K (sistema Kell) para todos os pacientes com cirurgias programadas e/ou com eventos clínicos agudos que não necessitem de transfusões emergenciais.

OBJECTIVE: Iron deficiency is the most common cause of anemia and one of the main factors in the clinical deferral of blood donors. This fact prompted the current study that aimed to determine the prevalence and etiology of anemia in blood donor candidates and to evaluate the hematological screening technique used for the exclusion of these donors. METHODS: This was a prospective study that compared two groups (Anemic and Non-anemic). Initially screening for anemia was performed by manually measuring hemoglobin (Bioclin® Kit); the results were subsequently compared with an automated screening method (Coulter T-890). The etiology was investigated by hemoglobin electrophoresis in alkaline and acid pH, Hb A2 dosage and measurement of the ferritin concentration by immunoagglutination. Differences and associations of interest were analyzed using the Yates and McNemar's Chi-square tests and the Fisher, Mann-Whitney, Wilcoxon and Kruskal-Wallis tests. RESULTS: The deferral rate due to anemia was 4.2%; iron deficiency was identified in 37.5% and beta thalassemia in 9.3% of the excluded candidates. There was a significant discrepancy between the two techniques used to measure hemoglobin with 38.1% of initially deferred donors presenting normal hemoglobin levels by the automated method. CONCLUSION: The results show a high rate of blood donors being deferred for anemia and confirm that iron deficiency is the most prevalent cause. The discrepancies found by comparing screening methods suggest that hemoglobin and hematocrit levels should be confirmed before deferring a donor due to anemia; this may increase supplies in blood banks.

OBJECTIVES: To identify the occurrence and the causes of platelet refractoriness in oncohematologic patients. INTRODUCTION: Platelet refractoriness (unsatisfactory post-transfusion platelet increment) is a severe problem that impairs the treatment of oncohematologic patients and is not routinely investigated in most Brazilian services. METHODS: Forty-four episodes of platelet concentrate transfusion were evaluated in 16 patients according to the following parameters: corrected count increment, clinical conditions and detection of anti-platelet antibodies by the platelet immunofluorescence test (PIFT) and panel reactive antibodies against human leukocyte antigen class I (PRA-HLA). RESULTS: Of the 16 patients evaluated (median age: 53 years), nine (56%) were women, seven of them with a history of pregnancy. An unsatisfactory increment was observed in 43% of the transfusion events, being more frequent in transfusions of random platelet concentrates (54%). Platelet refractoriness was confirmed in three patients (19%), who presented immunologic and non-immunologic causes. Alloantibodies were identified in eight patients (50%) by the PIFT and in three (19%) by the PRA-HLA. Among alloimmunized patients, nine (64%) had a history of transfusion, and three as a result of pregnancy (43%). Of the former, two were refractory (29%). No significant differences were observed, probably as a result of the small sample size. CONCLUSION: The high rate of unsatisfactory platelet increment, refractoriness and alloimmunization observed support the need to set up protocols for the investigation of this complication in all chronically transfused patients, a fundamental requirement for the guarantee of adequate management.

O objetivo deste trabalho foi caracterizar a qualidade de vida de pacientes hemofílicos em acompanhamento ambulatorial em serviço especializado. Foi feita abordagem quantitativa da qualidade de vida (QV) de pacientes hemofílicos acompanhados em ambulatório de hematologia de um hemocentro regional. A coleta de dados foi realizada por meio de entrevistas utilizando-se o Whoqol-bref e questionário adicional com variáveis sociodemográficas e clínico-epidemiológicas. Para análise dos dados utilizaram-se o Epi-info 6.04d e o SPSS, cujos resultados foram expressos através de distribuição simples, medidas de tendência central e dispersão, proporções e correlação de Pearson entre facetas e domínios. Foram entrevistados 23 pacientes, com média de idade de 21 anos; todos moravam com familiares, 47,8% eram residentes na cidade sede do hemocentro. Do total, 78,3% eram solteiros, 69,6% estudavam, sendo que 45,5% possuíam o 1º grau incompleto e 82,6% não trabalhavam. A maioria (91,3%) possuía hemofilia A. Quanto à avaliação da QV, 47,8% responderam ser boa e 55% possuíam um bom nível de satisfação com a saúde. O domínio psicológico apresentou o maior escore médio e o menor foi o do domínio meio ambiente. Com esse estudo conseguiu-se salientar a magnitude de alguns problemas dos hemofílicos.The objective of this work was to characterize the quality of life of hemophilic patients being followed up in a specialized service.

All reported that they live with their families, 47.8% were residents in Uberaba, 78.3% were single, 69.6% were students with 45.5% having a low level of education and 82.6% did not work. Of the 23 cases, 91.3% had hemophilia A. In respect to quality of life, 47.8% responded that their quality of life was good and 55% had a good level of satisfaction with their health. The psychological dominion presented the highest average score and the environment presented the lowest. This study highlights the magnitude of some problems of hemophilic patients.

A terapêutica transfusional é uma das mais importantes intervenções da medicina. Sendo a transfusão de sangue um procedimento complexo, não isento de riscos e frequente no Centro de Terapia Intensiva - CTI, torna-se essencial uma atuação profissional competente. O objetivo deste estudo é descrever a formação dos profissionais médicos e de enfermagem que atuam em CTI, relacionada à prática transfusional. A pesquisa foi realizada em um hospital universitário localizado no Triângulo Mineiro. Foi aplicado um instrumento estruturado e confeccionado para conhecer a participação dos profissionais na prática transfusional e qual a sua abordagem no processo de formação. Referem participar do processo transfusional 64% dos profissionais de saúde, os quais se sentem informados sobre o assunto. No entanto, 54% não participaram de atualização, 73% não participaram de programas de capacitação e 89% receberam informação sobre alguns aspectos da transfusão através de aulas teóricas. Considerando os resultados, torna-se necessário rever o processo de formação destes profissionais, bem como dos programas de capacitação sobre medicina transfusional oferecidos pelas instituições.Transfusion therapy is one of the most important interventions in medicine. However, blood transfusion is a complex proceeding, which is not devoid of risk but as it is common in the Intensive Care Unit (ICU), professional experience is essential. The objective of this study is to describe the level of instruction of medical and nursing professionals who work with transfusions in the Intensive Care Unit. This study was carried out in a University Hospital located in the Triângulo Mineiro region. A structured instrument was developed and applied to discover the professionals' participation in the transfusion practice and their approach to the process of instruction. About 64% of healthcare professionals participate in the transfusion process, all of whom felt they were informed about this subject. However, 54% did not participate in recycling training courses, 73% did not participate in training programs and 89% received information on some theoretical aspects of transfusion in classes. In light of the results, it is important to review the education of these professionals, as well as training programs on transfusion medicine offered by institutions.

Como o controle de qualidade dos concentrados de plaquetas (CP), feito na data de seu vencimento, não possibilita distinguir o momento e o procedimento que determina a eventual redução de sua qualidade, decidimos investigar, separadamente, a influência da coleta, da produção e da estocagem sobre a qualidade deste hemocomponente. Foram avaliados, em 33 CP randômicos, diariamente, durante cinco dias, os seguintes parâmetros: a agregação, o número de plaquetas e leucócitos, a pO2 e pCO2, o pH, sódio e potássio, a presença de swirling, grumos, hemácias e lipemia e cultura para bactérias. Observamos maior queda da agregação plaquetária com pares de agonistas durante a produção dos CP (de 99,4% para 59,8%, pAs quality control of platelet concentrates obtained at the expiration date does not distinguish between the different stages that may cause reductions in quality, such as collection and storage, we decided to separately investigate the influence of collection, processing and storage on the quality of these blood components. This study evaluated 33 random platelet concentrates daily for five days for the following parameters: aggregation, number of platelets and leukocytes, PO2 and PCO2, pH, sodium and potassium, the presence of swirling, platelet clots, red blood cells and lipemia, and bacteria culture. We observed a greater decrease in platelet aggregation with pairs of agonists during the production of platelet concentrates (from 99.4% to 59.8%, p

Adult T-cell leukemia/lymphoma is a lymphoproliferative disorder of mature T lymphocytes associated with infection with human T-cell lymphotrophic virus type I (HTLV-I). Adult T-cell leukemia/lymphoma is characterized by clinical and laboratory polymorphism that allows it to be classified into four distinct subgroups: smoldering, chronic, acute and lymphomatous types. We present here two cases of adult T-cell leukemia/lymphoma, respectively in the acute and lymphomatous forms of the disease. Case 1 was a 35-year-old woman who presented abdominal distension accompanied by hepatosplenomegaly, adenomegaly, skin lesions, positivity for anti-HTLV-I antibodies and leukocytosis with the presence of flower cells. Case 2 was a 38-year-old man who was admitted with generalized lymphadenomegaly, positivity for anti-HTLV-I antibodies, hypercalcemia and osteolytic lesions. In this paper, we correlate the clinical-laboratory findings of these two cases with data in the literature.A leucemia/linfoma de células T do adulto é um distúrbio linfoproliferativo de linfócitos T maduros associado à infecção pelo vírus linfotrópico de células T humanas tipo I (HTLV-I). A leucemia/linfoma de células T do adulto tem polimorfismo clínico e laboratorial, que a classifica em quatro subgrupos distintos entre si: smoldering, crônica, aguda e linfomatosa. Apresentamos neste artigo, dois casos de leucemia/linfoma de células T do adulto, respectivamente, nas formas aguda e linfomatosa da doença. O caso 1: uma paciente de 35 anos apresentava distensão abdominal com hepato-esplenomegalia, adenomegalia, lesões cutâneas, anticorpos anti-HTLV-I positivo e leucocitose com presença de flower cell. O caso 2: homem de 38 anos, internado com linfadenomegalia generalizada, anticorpos anti-HTLV-I positivo, hipercalcemia e lesões osteolíticas. Neste artigo correlacionamos os achados clínicos e laboratoriais destes dois casos com dados da literatura.

O objetivo deste estudo foi avaliar a ativação plaquetária através da P-selectina e o conteúdo de PDGF-AB e TGFbeta1, nos pacientes com esquistossomose que desenvolveram fibrose (F3), naqueles que não tiveram esta manifestação (F0) e nos controles (C). Os resultados mostraram que a percentagem de P-selectina nas plaquetas sem estímulo de agonistas foi de 10,6% nos F3; 11,1% nos FO, e 6,3% nos C e após a adição de ADP/adrenalina, foi de 44%; 25,3% e 42%, respectivamente. A dosagem do PDGF-AB e TGFbeta1 por plaquetas foi de 11,016ng/dL (F3); 3,172 ng/dL (F0) e 5,01ng/dL (C) e, (0,012ng/dL (F3); 5,27ng/dL (F0) e 4,66ng/dL (C), respectivamente. Em relação à P-selectina, concluímos que as plaquetas dos pacientes com esquistossomoses, apesar de estarem pré ativadas, mantiveram-se responsivas aos agonistas. O TFGbeta1 não apresentou diferença entre os três grupos, enquanto o PDGF-AB foi significantemente maior no grupo F3, sugerindo a participação deste no desenvolvimento da fibrose.The aim of this study was to evaluate platelet activation through P-selectin, and PDGF-AB and TGFbeta1 content, in schistosomiasis patients who developed fibrosis (F3) and who did not present this (F0), and in a control group (C). The results showed that the percentage of P-selectin in platelets without agonist stimulation was 10.6% in F3, 11.1% in F0 and 6.3% in C. After the addition of ADP/adrenaline, the percentages were 44%, 25.3% and 42%, respectively. The PDGF-AB and TGFbeta1 contents per platelet were 11,016ng/dl (F3), 3,172ng/dl (F0) and 5.01ng/dl (C) and 0,012ng/dl (F3), 5.27ng/dl (F0) and 4.66ng/dl (C), respectively. Concerning the P-selectin, we can conclude that platelets from patients with schistosomiasis continued to be responsive to agonists, despite being pre-activated. There were no differences in TGFbeta1 between the groups, but the PDGF-AB content was significantly higher in F3. This suggests that PDGF-AB may have some participation in the development of fibrosis.

Visando verificar a viabilidade do concentrado de plaquetas, após sua preservação com substâncias, que adicionadas ao sangue sejam capazes de destruir o Trypanosoma cruzi, testamos concentrado de plaquetas estocado com a violeta de genciana e a quinolina WR6026. A viabilidade foi avaliada através da contagem do número de plaquetas, da medida do pH e agregação plaquetária com par de agonistas durante seu período de estocagem. Alterações significativas foram observadas nos concentrados plaquetários tratados com violeta de genciana sugerindo comprometimento da viabilidade plaquetária. Com o WR6026 foram observados valores similares aos controles, abrindo perspectivas para o emprego deste sal na quimioprofilaxia da doença de Chagas transfusional, em regiões altamente endêmicas.In order to verify the viability of platelet concentrate during its preservation period when added with two trypanosomicidal chemical substances, gentian violet and quinoline WR6026, we tested these concentrates and verified the following parameters: number of platelets, pH and platelet aggregation test with a pair of agonists. Significant alterations were observed in the platelet concentrate treated with gentian violet suggesting important damage to the platelet viability. With WR6026 similar values to the controls were observed, opening new perspectives for the utilization of this salt for the chemoprophylaxis of transfusional Chagas' disease in highly endemic regions.

A dengue é um importante agravo nos contextos nacional e internacional. As ações de educação em saúde são indicadas para o seu controle. Os livros didáticos e materiais impressos são utilizados nas práticas educativas realizadas pelos setores da saúde e da educação. Objetivou-se, neste artigo, analisar, com base em um referencial teóricometodológico socioantropológico, as representações visuais sobre a dengue. Identificou-se um total de 262 imagens, sendo 204 provenientes dos materiais impressos coletados em Itaboraí (RJ) em 2010/2011 e 58 dos livros didáticos distribuídos nacionalmente, publicados entre 2008 e 2011. Verificou-se que o corpo é representado por meio de perspectiva biomédica para a abordagem da doença e sua sintomatologia. A carga da doença e seu impacto social são expressos de forma subliminar. Há valorização excessiva do papel do médico enquanto os agentes de endemias são caracterizados apenas como profissionais normatizadores. Já a população é estereotipada de acordo com sua faixa etária. Os impressos centram-se na difusão de imagens sobre a prevenção e o controle da doença, em especial o controle químico, e oslivros didáticos, no vetor. Na representação do vetor é valorizada a estética do grotesco por meio de monstros zoomorfos ou vampirescos. É dada ênfase, em ambos os materiais, à paisagem, onde criadouros artificiais do vetor são evidenciados de forma dogmática e o território é negligenciado.

Despite major advances in Brazilian blood transfusion therapy with a growing number of scientific publications, an increased number of repeat donors and a decline in serological ineligibility, a lack of conformity in the application of pre-transfusion tests that may compromise transfusion safety is still observed at transfusion agencies in the fringes of the blood transfusion therapy system. Additionally, although high rates of platelet transfusion refractoriness and significant rates of alloimmunization have been demonstrated in the international literature, few Brazilian centers have been concerned with the study of platelet alloimmunization and even fewer centers have evaluated the efficacy of platelet concentrate transfusion. As more than one million Brazilians, including many repeat blood donors, are listed in the National Bone Marrow Donor Registry (Redome), why not grant transfusion therapy services access to the HLA typing of these blood and marrow donors after obtaining their consent? And why not make use of the Redome data to evaluate the HLA compatibility of donors for alloimmunized patients who are candidates for bone marrow transfusion and who have already been typed? These measures, together with the identification of ABO and HPA antigens, will permit a complete assessment of platelet immunology, will guarantee the transfusion safety of this blood component, and will put Brazil at the same level as the so-called developed countries in terms of transfusion medicine.

Estudou-se a distribuição do sistema ABO em 222 controles e em 148 chagásicos crônicos, assintomáticos e sintomáticos, com diferentes formas anatomoclinicas (insuficiência cardíaca congestiva, visceromegalias e morte súbita). O foi calculado a partir de tabelas de contingência e pelo método de Woolf. OX², obtido por estes dois métodos, demonstra que a freqüência do grupo OX² foi significativamente menor nos chagásicos sintomáticos considerados como um todo e naqueles com "megas", em relação aos controles. Nos chagásicos falecidos subitamente observou-se maior freqüência de grupos B que nos controles, sendo o X² significativo apenas quando calculado por tabelas de contingência. A relativa proteção aparentemente conferida aos chagásicos do grupo O, no que se refere à evolução para formas sintomáticas da doença, se explicaria por antigenicidade cruzada entre populações do Trypanosoma cruzi e o sistema ABO ou por outros fatores que se deixam influenciar ou influenciam a distribuição dos grupos sangüíneos.

Dentre os agravos à saúde que têm acometido a população brasileira, destaca-se a dengue, a qual requer ações de controle integradas e participativas. O estudo investigou a existência ou não de ações intersetoriais entre os campos da saúde e da educação em uma área endêmica do Rio de Janeiro. Para tal, foram realizadas entrevistas semiestruturadas com sete professores de Ciências e Biologia de uma escola pública e dezesseis profissionais de saúde de uma unidade próxima à escola selecionada. As entrevistas foram submetidas à análise de conteúdo temática. Os resultados indicam que o conhecimento sobre a doença é superficial, falta diálogo entre os protagonistas dos setores investigados e os materiais informativos de que dispõem são escassos e por vezes inadequados.

Abstract Introduction: The clinical manifestations of sickle cell disease are related to the polymerization of hemoglobin S. The chronic hemolysis caused by this condition often causes the formation of gallstones that can migrate and block the common bile duct leading to acute abdomen. Objective: This study aimed to evaluate the profile of patients with sickle cell disease and cholelithiasis. Methods: Patients with sickle cell disease were separated into groups according to the presence or absence of cholelithiasis. Socioepidemiological and clinical characteristics, such as gender, age, use of hydroxyurea and the presence of other hemoglobinopathies were researched in the medical records of patients. Results: A hundred and seven patients with sickle cell anemia were treated at the institution. Of these, 27 (25.2%) had cholelithiasis. The presence of cholelithiasis was higher in the 11–29 age group than in younger than 11 years and over 29 years. No association was found for the presence of cholelithiasis with gender, use of hydroxyurea or type of hemoglobinopathy (hemoglobin SS, hemoglobin SC or sickle beta-thalassemia). Sixteen of the patients had to be submitted to cholecystectomy with 14 of the surgeries being performed by laparoscopy. Complications were observed in three patients and one patient died for reasons unrelated to the surgery. Conclusion: A quarter of patients with sickle cell disease had gallstones, more commonly in the 11- to 29-year age range. Patients should be monitored from childhood to prevent cholelithiasis with preoperative, intra-operative and postoperative care being crucial to reduce the risk of complications in these patients.

Resumo As doenças negligenciadas correspondem a um grupo de agravos de relevância nacional e internacional. O tema das doenças negligenciadas precisa transcender o setor da saúde e sua abordagem deve estar presente também no ensino. Além disso, o controle e a prevenção destes agravos, bem como a saúde, necessitam ser compreendidos como um fenômeno multifacetado. Analisamos o tema das doenças negligenciadas nas propostas curriculares dos estados brasileiros destinados à disciplina de Ciências do 6º ao 9º ano do ensino fundamental. Reunimos ao todo 24 propostas curriculares. Os resultados apontaram que somente nove destes currículos abordaram as doenças negligenciadas como conteúdos de relevância e que persiste ainda a ideia de que a saúde é um bem restritamente biológico ou produto de ações prescritivas e ganhos cognitivos.
