Presença de formas amastigotas de Leishmania chagasi e perfil leucocitário no aparelho reprodutivo de cães

A leishmaniose visceral (LV) é uma zoonose causada pelo protozoário Leishmania (Leishmania) chagasi. A leishmaniose visceral canina (LVC) é a doença de maior relevância zoonótica. Usualmente, a infecção ocorre entre um hospedeiro invertebrado para um hospedeiro vertebrado, entretanto, a transmissão na ausência do vetor já é conhecida. O objetivo principal deste estudo foi identificar a presença de formas amastigotas, quantificar as células leucocitárias, estimar o risco relativo da presença de formas amastigotas no aparelho reprodutivo de cães sorologicamente positivos com e sem sinais clínicos. Para isso, foram utilizados cães sem raça definida, sexualmente maduros e testados sorologicamente para LVC (com sinais clínicos, n=25; sem sinais clínicos, n=25), que após eutanásia, tiveram fragmentos de testículo, epidídimo (cabeça, corpo e cauda) e glândula prostática (selecionados ao acaso) impressos em lâminas. Um grupo de 20 cãs sorologicamente negativos e sem sinais clínicos foi usado como controle. Amostras do baço foram incluídas como controle parasitológico positivo. O percentual de linfócitos foi superior (P<0,05) no corpo e cauda do epidídimo, assim como no testículo. Macrófagos foram superiores (P<0,05) apenas nas regiões do corpo e cauda epididimais. A presença de amastigotas correlacionou-se entre as distintas regiões do aparelho reprodutivo. Nos sintomáticos variaram entre 0,50 a 0,80 e entre 0,79 a 0,95 nos assintomáticos. A presença de amastigotas no testículo dos cães sintomáticos foi 6,5 vezes superior aos cães assintomáticos. Os resultados obtidos demonstram o potencial epidemiológico da transmissão venérea da doença, principalmente em áreas onde os programas de controle da LVC não consideram esta forma de transmissão, que pode ser importante em populações caninas não esterilizadas.

Perfil das doenças glomerulares em um hospital público do Distrito Federal

INTRODUÇÃO: As doenças glomerulares são uma causa frequente de doença renal crônica, sobretudo nos países em desenvolvimento. OBJETIVO: O objetivo deste estudo foi determinar o perfil destas glomerulopatias em um hospital público da cidade de Brasília, Distrito Federal. MÉTODOS: Foram realizadas 121 biopsias renais pela equipe de nefrologia do Hospital Regional da Asa Norte (HRAN) entre agosto de 2005 e maio de 2009. Foram excluídas oito biopsias realizadas em pacientes transplantados renais e analisados os prontuários dos 113 pacientes restantes. Dados analisados: sexo, idade, exames laboratoriais, síndrome glomerular, diagnóstico clínico, grau de fibrose intersticial, uso de imunossupressores, necessidade de diálise e desfecho clínico. RESULTADOS: A média de idade foi 34,9 ± 16,2 anos, com predomínio masculino (51,3%). As principais síndromes glomerulares foram: síndrome nefrótica (41,6%) e glomerulonefrite rapidamente progressiva (35,4%). Entre as glomerulopatias primárias, houve predomínio da glomeruloesclerose segmentar e focal (26,9%) e da nefropatia por IgA (25%) e entre as secundárias a nefrite lúpica (50%) e a glomerulonefrite proliferativa exsudativa difusa (34,2%). A maioria dos pacientes fez uso de imunossupressores (68,1%) e quase um terço deles (29,2%) necessitou de diálise durante a internação. Evoluíram para terapia dialítica crônica 13,3% dos pacientes e 10,6% evoluíram a óbito. CONCLUSÃO: Este estudo poderá contribuir para melhor entendimento epidemiológico das doenças glomerulares no Distrito Federal, orientando na adoção de políticas públicas visando permitir rápido diagnóstico e manejo clínico das mesmas.

Prevalência da infecção por HPV e perfil das mulheres frente ao exame de papanicolau no município de São José de Mipibú/RN.

The Human Papillomavirus (HPV) infection is the major sexually transmitted disease all over the world. There are many factors associated to infection and the virus persistency in the organism. This study aims to evaluate the women's knowledge, attitudes and practice about the Papanicolaou test (Pap), as well as analyze the HPV and Chlamydia trachomatis infections prevalences in sexually active women from the city of São José do Mipibu/RN/Brazil. This research was divided in two steps (step I and step II), using different methodologies and samples each. The samples collected in each step, even socio-demographic or from uterus cervix, are from different patients e were analyzed separated. In step I was evaluated 267 rural and urban zone women s knowledge, attitudes and practices about the Pap by home interview. In the step II were included 605 women with age ranged from 15 to 71 years old, with mean of 33,5 years old and from each one were collected two cervical samples, one for Pap and other for molecular biology, beside the epidemiological interview to investigate the correlation between prevalence of HPV infection and risk factors. To molecular analyses, the samples were processed using a mammal rapid DNA extraction technique protocol. For C. trachomatis DNA detection were used the CP24/27 primers, and GP5+/GP6+ to HPV. PCR products were analyzed by electrophoresis on 8% polyacrylamide gels, followed by silver staining. The results of the step I showed that, in spite of only 46,1% of the interviewed women they have demonstrated to possess appropriate knowledge on the Pap test, the attitude and practice proportions were significantly larger, 63,3% and 64,4% respectively. The largest education degree presented association with adaptation of the knowledge, attitudes and practice, while neglect, lack of solicitation of the exam for the doctor and shame, came as main barriers for the accomplishment of the exam. In the stage II the HPV general prevalence was 28,9%, being 26,7% in the women with normal cytology or benign alterations, 26,7% in the ones that had atypical squamous cells of undetermined significance (ASC-US) and 80% in those with Low grade squamous intraepithelial lesion (LSIL). the HPV infection prevalence was larger in the patients with up to 30 years of age and in the unmarried women, and those that had more than one sexual partner presented larger infection risk. The results show that the sexual relationship with multiple partners increased the infection risk for HPV and consequently the possibility of the occurrence of lesions uterine cervix

Estudo da frequência e perfil epidêmico-sorológico da toxoplasmose ocular em pacientes atendidos no ambulatório de oftalmologia do hospital universitário onofre lopes no município de Natal, Rio Grande do Norte

Toxoplasmosis, provoked by the intracellular parasite Toxoplasma gondii, is one of the most prevalent parasitoses in the world. In humans, transmission occurs by three evolutionary forms of the parasite: oocysts, tissue cysts and tachyzoites. Wild and domestic felines are definitive hosts. The ocular form of toxoplasmosis can be of congenital origin with early or late clinical manifestations, or acquired after birth. T. gondii is considered the main culprit for most cases of infectious uveitis. This study aimed at assessing ocular toxoplasmosis, relating it to factors associated to the patient s lifestyle and describing the epidemic-serological and clinical profile of affected individuals. A cross-sectional study was conducted with a population of 159 patients. Univariate analysis (odds ratio) was used to evaluate the data, with a confidence interval of 95% and p-value < 0.05. A prevalence of 4% of ocular toxoplasmosis was observed in the population of patients treated at an ophthalmological clinic. Of patients directly examined by immunoenzymatic assay (MEIA-AxSYM®- Microparticle Enzyme Immune Assay), considering only uveitis, a frequency of anti-T. gondii of 73%, most of whom exhibited titulation between 40-99 UI IgG/mL. With respect to location of ocular lesions, bilaterality was observed in 57% of patients assessed by the ophthalmoscopy technique. When compared with the results of an active search of medical records, a similarity in ocular toxoplasmosis (74%) and bilateral lesion location (55%) was observed. Type I lesion was the most frequent type observed, with intraocular disposition in the macula. An epidemiological survey revealed that direct contact with cats; consuming raw or poorly cooked meat and direct contact with the soil were significantly associated with greater likelihood of acquiring ocular toxoplasmosis. Sample characterization in relation to age range was significant for patients between 31 and 40 years [χ², chi-square test (p = 0.04)], but population traits such as schooling, sanitary district, and monthly income were not significant. Results confirm that ocular toxoplasmosis is widely distributed in the metropolitan area of Natal, Brazil, with significant prevalence of ocular lesions provoked by T.gondii. It is suggested that sanitary authorities exert greater control in order to minimize the risk of toxoplasmic infection, mainly in pregnant women.

Perfil de mortalidade de idosos no Rio Grande do Norte: estudo comparativo entre duas faixas etárias e fatores relacionados

Measures of mortality represent one of the most important indicators of health conditions. For comprising the larger rate of deaths, the study of mortality in the elderly population is regarded as essential to understand the health situation. In this sense, the present study aims to analyze the mortality profile of the population from 60 to 69 (young elders) and older than 80 years old (oldest old) in the Rio Grande do Norte state (Brazil) in the period 2001 to 2011, and to identify the association with contextual factors and variables about the quality of the Mortality Information System (SIM). For this purpose, Mortality Proportional (MP) was calculated for the state and Specific Mortality Rate by Age (CMId) , according to chapters of ICD- 10, to the municipalities of Rio Grande do Norte , through data from the Mortality Information System (SIM) and the Brazilian Institute of Geography and Statistics (IGBE). In order to identify groups of municipalities with similar mortality profiles, Nonhierarchical Clustering K-means method was applied and the Factor Analysis by the Principal Components Analysis was resort to reduce contextual variables. The spatial distribution of these groups and the factors were visualized using the Spatial Analysis Areas technique. During the period investigated, 21,813 younger elders deaths were recorded , with a predominance of deaths from circulatory diseases (32.75%) and neoplasms (22.9 %) . Among the oldest old, 50,637 deaths were observed, which 35.26% occurred because of cardiovascular diseases and 17.27% of ill-defined causes. Clustering Analysis produced three clusters to the two age groups and Factor Analysis reduced the contextual variables into three factors, also the sum of the factor scores was considered. Among the younger elders, the groups are called misinformation profile, development profile and development paradox, which showed a statistically significant association with education and poverty and extreme poverty factors, factorial sum and the variable related to underreporting of deaths. Misinformation profile remained in the oldest old group, accompanied by the epidemiological transition profile and the epidemiological paradox, that were statistically associated with the development and health factor, as well as with the variables that indicate the SIM quality: proportion of blank fields about the schooling and underreporting. It proposed that the mortality profiles of the younger elders and oldest old differ on the importance of the basic causes and that are influenced by different contextual aspects , observing that 60 to 69 years group is more affected by such aspects. Health inequalities can be reduced by measures aimed to improve levels of education and poverty, especially in younger elders, and by optimizing the use of health services, which is more associated to the oldest old health situation. Furthermore, it is important to improve the quality of information for the two age groups

Perfil materno e dos recém-nascidos nascidos vivos na primeira década do século XXI em município do interior paulista com ênfase na prematuridade

The concern with infant mortality has been a priority in public policies, especially for Brazil to achieve the Millennium Development Goal number four: reducing child mortality by 75% by the year 2015. It is known that prematurity has an intimate relationship with mortality of children under one year and therefore it is necessary an effective intervention in risk factors linked to premature births. To evaluate the profile of mothers and newborn babies living in Botucatu-SP, in the period 2001 to 2009, focusing on prematurity. A quantitative study, retrospective, descriptive, epidemiological, from the Information System Newborn Alive. The prevalence of preterm births was 15.1%, and low birth weight 14.7%. Among infants, the Apgar score below 7 at 1 and at 5 minutes was 13.1% and 2.4% respectively. Considering the total of pregnant women studied, 20.3% were adolescents and 10.3% were aged 35 years or more and most (63.2%) had eight or more years of school approval. The profile of mothers of premature infants shows that 23.6% were teenagers, 14.1% had at least 35 years and 60.4% had at least primary education. With regard to premature deliveries, caesarean sections and 58.4% were between the total newborns, this type of delivery was achieved in 46.6% of cases. Prematurity was associated with an Apgar score below seven in the first and fifth minutes of life, presence of malformation and multiple pregnancy. Among maternal variables, prematurity was associated with extremes of maternal age, maternal education, history of stillbirth, primiparas, white and presence of the mother's partner. With regard to delivery was associated with cesarean section and outside the hospital. This study assessed maternal characteristics associated with prematurity and point out how relevant the pregnancies at the extremes of age and those that occur in women with low education level, indicating the interference...

Perfil das gestantes acompanhadas em uma equipe de saúde da família do interior paulista

O cuidado a gestante apresenta-se como prioridade na Estratégia Saúde da Família (ESF), haja vista que durante a gestação a assistência pré-natal é garantia para prevenção de complicações e manutenção da saúde da mulher e de seu filho. Com intuito de fortalecer a assistência, o presente estudo objetivou analisar o perfil das gestantes acompanhadas por uma equipe de saúde da família do interior paulista - ESF Jardim Itapema, Guará/SP, em 2010. Essa equipe apresentou número de gestantes cadastradas (n=24) mais elevado do que número esperado de gestantes (n=18), conforme parâmetros para programação local. Foi realizado estudo quantitativo, epidemiológico, transversal referente às características clínicas, sociodemográfica e familiares dessas gestantes, através de registros secundários do Sistema de Informação sobre Pré-Natal (SISPRENATAL) e Sistema de Informação da Atenção Básica (SIAB). Os resultados mostram que as gestantes estão na faixa etária entre 15 e 29 anos (79,15%), de cor da pele branca (50%) e parda (33,34%), ensino fundamental incompleto (50%), casado ou em união estável (79,16%), com ocupação do lar (83,33%). Metade delas deu início ao pré-natal no 1º trimestre, apenas 4,54% eram Primíparas. O tipo de parto predominante em gestações anteriores foi cesariana (62,50%), e a maior parte não possui agravos associados à gestação atual (95,83%). Suas famílias são chefiadas por homens (91,66%), adultos jovens, entre 20 a 29 anos (58,29%), com ensino médio incompleto ou menos (75%). Os demais habitantes de seus domicílios apresentam menos de 14 anos e são homens, em sua maioria. Os domicílios são de tijolo, casas próprias (62,5%) ou alugadas (29,16%), com 3 a 5 cômodos (62,5%), energia elétrica, água tratada e coleta regular do lixo. Os meios de comunicação que as gestantes mais utilizam são televisão, rádio e telefone (91,65%). Participam de grupos comunitários apenas religiosos (45,83%). Maioria das gestantes e seus familiares (83,33%) não possuem plano de saúde, em caso de doença procuram em primeiro lugar a Unidade de Saúde (58,33%). As intervenções propostas pela equipe da ESF na abordagem dessas gestantes devem considerar seus aspectos clínicos e subjetivos, portanto devem ser ampliadas, no sentido de incorporarem o trabalho interdisciplinar e a ação intersetorial. Com isso, é importante que a atuação da ESF - para garantia da assistência à saúde resolutiva e de qualidade - abrace dimensões acolhedoras, no apoio às gestantes e suas famílias, para o enfrentamento positivo de suas necessidades de saúde, considerando seus contextos de vida.

Determinação do perfil de compostos voláteis e avaliação do sabor e aroma de bebidas produzidas a partir da erva-mate (Ilex paraguariensis)

Volatile compounds from green and roasted yerba mate were analyzed by gas chromatography/mass spectrometry and the flavor profile from yerba mate beverages was determined by descriptive quantitative analyses. The main compounds tentatively identified in green mate were linalool, alpha-terpineol and trans-linalool oxide and in roasted mate were (E,Z)-2,4-heptadienal isomers and 5-methylfurfural. Green mate infusion was qualified as having bitter taste and aroma as well as green grass aroma while roasted mate was defined as having a smooth, slightly burnt aroma. The relationship between the tentatively identified compounds and flavor must be determined by olfatometric analysis.
