Detecção da hanseniase e a humanização do cuidado: ações do enfermeiro do programa de saúde da familia

The Municipality of São Gonçalo in the Metropolitan Region of Rio de Janeiro - Brazil is considered an endemic area for leprosy according to the Ministry of Health. From this observation, we sought to identify with this work which  actions are performed by nurses from Family Health Program (PSF) to detect leprosy and what care they  provide to people affected by the disease, with the focus on humanization. Thus, we performed descriptive, qualitative and field units in the health of the family of that city, with thirty-one nurses through interviews with open questions. Two categories emerged: the detection actions made by the  nurse, the care given to people affected and the humanization of care needed. It was concluded that the actions taken by the nurses do not follow a single standard and that some lack the necessary training to function with  users of PSF affected by leprosy.El municipio de São Gonçalo, en la Región Metropolitana de Río de Janeiro - Brasil es considerado una zona endémica de la lepra de acuerdo con el Ministerio de Salud. De esta observación, hemos tratado de identificar con este trabajo cuáles son las acciones realizadas por las enfermeras en El Programa de Salud Familiar (PSF) para detectar la lepra y qué tipo de atención prestan a las personas afectadas por la enfermedad, centrándose en la humanización. Así, se realizó investigación descriptiva, cualitativa y de campo en las unidades de salud de la familia de esa ciudad, con treinta y un enfermeros a través de entrevistas con preguntas abiertas. Emergiendo dos categorías: las acciones de detección de la enfermera del PSF, la atención prestada a las personas afectadas y la necesaria humanización de esos cuidados. Se concluyó que las medidas adoptadas por las enfermeras no siguen un estándar único y que algunas no tienen la capacitación necesaria para desenvolverse con los usuarios del PSF afectadas por la lepra.O Município de São Gonçalo na Região Metropolitana do Rio de Janeiro - Brasil é considerado zona endêmica para a Hanseníase segundo dados do Ministério da Saúde. A partir dessa constatação, buscou-se com o presente trabalho identificar quais as ações realizadas pelo enfermeiro do Programa de Saúde da Família (PSF) para detectar a hanseníase e qual o cuidado por ele oferecido às pessoas atingidas pela doença, tendo como foco a humanização. Assim, foi realizada pesquisa descritiva, qualitativa e de campo nas unidades de saúde da família do referido município, com trinta e um enfermeiros através de entrevista com perguntas abertas. Emergindo duas categorias: as ações do enfermeiro do PSF na detecção; os cuidados ministrados às pessoas atingidas e a necessária humanização desses cuidados. Concluiu-se, que as ações realizadas pelos enfermeiros não obedecem a um padrão único e que alguns não possuem a necessária capacitação para atuar com os usuários do PSF atingidos pela hanseníase

Lymphocyte subsets in human immunodeficiency virus-unexposed Brazilian individuals from birth to adulthood

Ethnic origin, genetics, gender and environmental factors have been shown to influence some immunologic indices, so that development of reference values for populations of different backgrounds may be necessary. We have determined the distribution of lymphocyte subsets in healthy Brazilian individuals from birth to adulthood. Lymphocyte subsets were determined using four-colour cytometry in a cross-sectional study of 463 human immunodeficiency virus-unexposed children and adults from birth through 49 years of age. Lymphocyte subsets varied according to age, as previously observed in other studies. However, total CD4+ T cell numbers were lower than what was described in the Pediatric AIDS Clinical Trials Group P1009 (PACTG P1009), which assessed an American population of predominantly African and Hispanic backgrounds until the 12-18 year age range, when values were comparable. Naïve percentages and absolute values of CD8+ T cells, as assessed by CD45RA expression, were also lower than the PACTG P1009 data for all analysed age ranges. CD38 expression on both CD4+ and CD8+ T cells was lower than the PACTG P1009 values, with a widening gap between the two studies at older age ranges. Different patterns of cell differentiation seem to occur in different settings and may have characteristic expression within each population.Universidade Federal de São Paulo (UNIFESP) Departamento de MedicinaCentro Assistencial Cruz de MaltaUniversidade Federal de São Paulo (UNIFESP) Departamento de PediatriaUNIFESP, Depto. de MedicinaUNIFESP, Depto. de PediatriaSciEL

Duffy blood group gene polymorphisms among malaria vivax patients in four areas of the Brazilian Amazon region

<p>Abstract</p> <p>Background</p> <p>Duffy blood group polymorphisms are important in areas where <it>Plasmodium vivax </it>predominates, because this molecule acts as a receptor for this protozoan. In the present study, Duffy blood group genotyping in <it>P. vivax </it>malaria patients from four different Brazilian endemic areas is reported, exploring significant associations between blood group variants and susceptibility or resistance to malaria.</p> <p>Methods</p> <p>The <it>P. vivax </it>identification was determined by non-genotypic and genotypic screening tests. The Duffy blood group was genotyped by PCR/RFLP in 330 blood donors and 312 malaria patients from four Brazilian Amazon areas. In order to assess the variables significance and to obtain independence among the proportions, the Fisher's exact test was used.</p> <p>Results</p> <p>The data show a high frequency of the <it>FYA/FYB </it>genotype, followed by <it>FYB/FYB, FYA/FYA</it>, <it>FYA/FYB-33 </it>and <it>FYB/FYB-33</it>. Low frequencies were detected for the <it>FYA/FY</it>^<it>X</it>, <it>FYB/FY</it>^<it>X</it>, <it>FYX/FY</it>^{<it>X </it>}and <it>FYB-33/FYB-33 </it>genotypes. Negative Duffy genotype (<it>FYB-33/FYB-33</it>) was found in both groups: individuals infected and non-infected (blood donors). No individual carried the <it>FY</it>^<it>X</it><it>/FYB-33 </it>genotype. Some of the Duffy genotypes frequencies showed significant differences between donors and malaria patients.</p> <p>Conclusion</p> <p>The obtained data suggest that individuals with the <it>FYA/FYB </it>genotype have higher susceptibility to malaria. The presence of the <it>FYB-33 </it>allele may be a selective advantage in the population, reducing the rate of infection by <it>P. vivax </it>in this region. Additional efforts may contribute to better elucidate the physiopathologic differences in this parasite/host relationship in regions endemic for <it>P. vivax </it>malaria, in particular the Brazilian Amazon region.</p
