Análise de vacinas contra o sorotipo 3 do vírus da doença de marek por PCR em tempo real e cultivo celular.

A doença de Marek (MD), causada por um alfaherpesvírus, é uma enfermidade linfoproliferativa que acomete principalmente galinhas. Como não existe tratamento, a melhor forma de prevenção e controle da MD é através do uso de vacinas atenuadas, que vêm sendo usadas desde 1970. Este trabalho descreve a análise de vacinas vivas congeladas contra o sorotipo 3 do vírus da doença de Marek (herpesvírus de peru – HVT) por PCR em tempo real (qPCR) e por cultivo em células de embrião de galinha. Foram avaliadas três vacinas (cepa FC126) provenientes de distintos fabricantes. As análises da homogeneidade inter e intra-lote apresentaram, respectivamente, média ± desvio padrão de 2,6 ± 1,7%, 2,1 ± 1,1% e 1,2 ± 0,1% e média ± desvio padrão de 1,5 ± 0,1%, 1,2 ± 0,8% e 1,0 ± 0,3% para A, B e C, respectivamente. A qPCR subestimou os títulos das vacinas concentradas 4x e superestimou os títulos das vacinas diluídas 8x, enquanto o cultivo celular superestimou os títulos das vacinas concentradas. As vacinas apresentaram quantidades diferentes de células/dose e unidade formadoras de placa/dose. Conseqüentemente, a relação PFU/célula também foi diferente, o que demonstra a necessidade de construção de curvas diferentes, para cada fabricante, para a titulação por qPCR.

Associação entre a ingestão de macronutrientes e a obesidade abdominal com a doença arterial coronária

Introdução: A incidência da doença arterial coronária é uma das principais causas de morbidade e motalidade em diversos países e o estudo dos fatores de risco têm grande importância na prevenção e no tratamento dessa enfermidade. Entre outros fatores, a obesidade e a obesidade abdominal têm sido associadas com a maior incidência de DAC. A ingestão diária de nutrientes também pode estar relacionada com essa doença, porém, uma vez que a alimentação é complexa e contém diversos nutrientes, ainda não foi possível elucidar o impacto da alimentação no risco de desenvolver a doença arterial coronária. Objetivo: Avaliar a relação entre o consumo alimentar diário, a presença de obesidade abdominal e achados angiográficos de obstrução arterial em pacientes portadores de cardiopatia isquêmica, submetidos a cateterismo cardíaco. Métodos: Foi realizado um estudo transversal, com 284 pacientes submetidos a cateterismo cardíaco, da unidade de hemodinâmica de um hospital universitário. Foi avaliada a RCQ, o IMC, a ingestão alimentar diária através de um inquérito nutricional, a análise bioquímica do sangue e a avaliação do laudo do cateterismo cardíaco. Resultados: Dos pacientes avaliados, 172 indivíduos (60,6%) apresentavam alterações em uma ou mais artérias coronárias. A ingestão média diária de calorias foi de 2450,56 Kcal/dia. O consumo de proteínas foi em média 1,66 g/Kg/dia, de carboidratos foi de 3,83 g/Kg/dia e de lipídeos foi de 1,21 g/Kg/dia. A idade, o sexo masculino, os níveis séricos de triglicerídeos, o consumo de álcool e a glicemia em jejum foram estatisticamente significativos na análise multivariada. Conclusão: Nos pacientes avaliados, o consumo diário de calorias encontra-se adequado, porém a ingestão de proteínas, carboidratos e lipídeos estão inadequados. Em relação aos fatores de risco para DAC, as mulheres apresentaram maior associação para desenvolver a síndrome metabólica do que os homens.

Prevalência de excesso de peso em pré-escolares na cidade do Natal

Obesity is currently considered a public health problem and there has been growing interest in the study of various aspects related to this infirmity such as: epidemiology, diagnosis, treatment, prevention and others. Thus, the purpose of this study was to determine the prevalence of weight excess and overweight in preschoolers in Natal, Brazil and relate them to variables such as gender, age, type of school (public or private) and zones of the city (east/south and north/west). This is a transversal study, carried out in Natal, Brazil between August and September 2004, in 20 public and 20 private schools/day care centers selected by the systematic sampling method. We measured the weight and height of 3721 students between the ages of 2 and 6 years. The children were stratified, according to age, into age group 1 (2 to 4 years) and age group 2 (5 and 6 years) and according to the region of the school, into north/west and east/south zones, the regions with the smallest and highest quality of life indices in the city, respectively. Children were considered to have weight excess when BMI ≥ 85th percentile, including those with BMI ≥ 95th percentile and overweight when BMI ≥ 95th percentile. The prevalence of weight excess was 26.5%, and of overweight 12.4%. There was greater prevalence of weight excess in the private schools and in the east/south zones. Overweight displayed the same epidemiologic profile, with a greater prevalence in private schools and in the east/south zones. The prevalence of weight excess in preschoolers in Natal, Brazil is high and is related, above all, to private schools and to those located in the highest quality of life areas. Therefore, prevention programs should be implanted in elementary schools in order to decrease weight excess and possible associated co-morbidities. This research project met the norms established by PPGCSa/UFRN and aimed at promoting the interrelation between different researchers and between different fields of knowledge, using multi and interdisciplinary concepts. This study was enriched by the interaction between the following professionals: pediatrician, pediatric gastroenterologist and physician nutrition specialist, pediatric endocrinologist, epidemiologist and biostatistician

Ações dos agentes comunitários de saúde diante do usuário da estratégia saúde da família com estados depressivos no Município de Abaiara-CE-BR

Brazilian health public assistance is going through two Reforms, Sanitary and Psychiatric, and through these the assistance is guaranteed in the three levels: primary, secondary and tertiary. Thus, mental health assistance should be offered since preventive cares until the ones that demand larger technological apparatus. Programs like Health Community Agent's Program (HCAP) and Family Health Strategy (FHS), besides increasing the services coverage, have been making possible the system reorientation in the meaning of integrality, universalization and equity. Thus, united intervention of mental health team and FHS can offer several benefits to the population, providing assistance and follow-up to patients with mental disorder. It was aimed to assess health community agents facing the user of Family Health Strategy in depressive state. This quanti-qualitative study took place in the municipal district of Abaiara-CE. Semi-structured interview was applied with health community agents and Beck Depression Inventory with the users registered in Family Health Strategy. It was verified that among the 64 users interviewed, 12.5% didn't present symptoms of depression, 10.9% presented symptoms of light depression, 14.1% symptoms of moderate depression and 62.5% symptoms of serious depression. For the 22 health community agents interviewed, they all reported the existence of people with symptoms of depression in their personal micro-areas, being difficult to work with them, once the FHS team is not qualified to work with mental health problems. It was verified that the Municipal district doesn't have specialized professionals, making difficult the routing and treatment. Based on these results, it was concluded that in spite of the articulation of mental health with FHS is necessary and benefactor to the population, it still doesn't exist, worsening the situation, mainly in small Municipal districts, once they don't have mental health services. Thus, the population is exposed and without follow-up, which allows the identification of installed diseases and with gravity, like depression, because there are no prevention and control activities. It is recommended, due the extreme need, the elaboration and implantation of a mental health program in these municipal districts, articulated with FHS

Biossegurança e a saúde do trabalhador na assistência a pacientes em tratamento onco-hematológico

In recent years, the biosafety has been made possible a new look which are based the conceptions of health and illness process, as well as human needs. This new vision is focused on health vigilance that is referenced specifically in this study to the worker s health. The health of workers is essential for the prevention and control of epidemics and outbreaks of diseases as well as emerging and reemerging diseases. The present study wants to show the importance of biosafety measures for health workers, showing them through the concepts in their daily work. It is also to direct the use of biosafety measures in the care of oncology and hematology patients care, because of its infection susceptibility. OBJECTIVES: To analyze the conceptions of health workers in the biosafety pratice to the patients in oncological and hematological treatment in an oncological institution in Natal / RN, as well as make a socio-demographic profile of these workers and to know their difficulties to adequate biosafety measures. METODOLOGIA: The research is exploratory descriptive with qualitative approach, using the technique of oral history. The use of this technique is justified for the possibility of analyze the conceptions of health workers in the face of biosafety measures. From the definition of analysis categories that have emerged in the study. The categories were: daily work, education, occupational risk and onco-hematological care. The research population was the health workers who provide care to patients in oncological and hematological treatment. The study was conducted in the League against Cancer, in Natal / RN, specifically in the unit Luiz Antonio Hospital. Data collections were conducted from June to August of 2011 and were interviewed sixteen employees who assist in oncology and hematology. Structured interviews were conducted in three shifts, given the prospects of expanding the possibilities of analysis of the biosafety concepts. After data collection, the interviews were analyzed qualitatively by the technique of oral history. This genre, thematic oral history is a modern resource used for preparation of documents, files and studies concerning the social experience of people and groups with the construction of a script prior to the interview moment (MEIHY, 2002). ANALYSIS OF INFORMATION: It was made a reflection about the concepts and practices of professionals who take care of patients in oncology and hematology as well as its relation to biosafety measures. The speech of employees revealed that the adoption has been very supportive of these standards, although some have been highlighted gaps in the understanding of employees in relation to biosafety and the proposed categories. CONCLUSION: The analysis of information showed that biosafety has been cited by employees as an immeasurable benefit to safety and occupational health. And the strengths marks in their understanding were: the excellence of care and safety in occupational diseases risk reduction and infections resulting from their work activities, despite some difficulties in adopting appropriate biosafety standards

Atenção à saúde da pessoa idosa na estratégia saúde da família no município de Santo Antônio/RN: um estudo de caso

According to demographic estimates, by the year 2025 Brazil will be the sixth country in the world in number of elderly. For this reason, it is a purpose of public policies to help people to reach that age being healthier. The current health care model of health surveillance through the Family Health Strategy (EFS, in portuguese) is configured as a gateway into the care of the elderly in the Unified Health System (SUS, in portuguese). It is also an area of development of practices to promote health, prevention and control of chronic nondegenerative diseases. The aim of this study was to analyze the health care of the elderly provided by ESF professionals for the achievement of a full care. The study is descriptive case study with a quantitative approach, performed in the city of Santo Antônio/RN. The population included all health professionals, who are FHS members of the city that agreed to participate of the survey, a total of 80 professionals. Data were collected using a structured questionnaire, having mostly closed questions and divided into two parts: one containing sociodemographic information of health professionals and vocational training and the other, the activities carried on by the professionals in senior care, being analyzed from a database tabulated in a spreadsheet and discussed according to the descriptive statistics in tables, graphs and charts using frequencies, medians and values of central tendency. It was verified a predominance of professionals who finished highschool, mostly female, aged from 30 to 34 years old, with training completed in the last 10 years, without being graduated in the field of geriatrics or gerontology and mostly without training in gerontology. Family members and caregivers were the components of the social support network most identified by the professionals (66.3%).The elderly access to the Family Health Basic Unit was considered by83.8% of professionals as the most important factor that interferes in the activities of health care of the elderly. Considering the inclusion of the family in care: 98.8% of professionals consider the family as one of the goals of care, but 82.5% assist the family to know their role and participate in the care of the elderly, emphasizing that no professional makes use of tools for evaluating the functionality of the family. Regarding the actions taken to assist the elderly, 91.25% have home visits program to the elderly, 88.75% use the host program; 77.5% know the habits of life, cultural, ethical and religious values of the elderly, their families and their community ;51.25% complement the activities through intersectoral actions, 50%participate in groups of living with the elderly; 33.75% keeps track and maintain updated the health information of the elderly; 11.25% of the professionals perform the Single Therapy Planning (PTS, in portuguese) and few implement the actions to promote health according to PTS; there is a deficit in the number of professional categories in the identification and monitoring of the frail older people in their households. It is concluded that the health care of the elderly developed by ESF professionals differs among the professional categories. It was identified weaknesses in the promotion of an active and healthy aging and also in the establishment of an integrated and full care of the elderly. It is recommended the adoption of permanent educational activities by the City Management, initially for ESF professionals in the the perspective of the guidelines of the National Policy of Health Care for the Elderly and later to the other professionals that are part of the health care network of the elderly, at all levels of care in the city for the development of strategies and practices that promote the improvement of the quality of healthcare for the elderly, expecting concrete and effective results in terms of promoting health within Brazilian reality

Para uma crítica da razão socioeducativa em entidades assistenciais

Buscou-se cartografar as instituições de assistência social que atendem à infância e à adolescência consideradas em situação de risco pessoal e social, em um município do interior do estado de São Paulo, utilizando o instrumental da análise institucional. O papel de membro do Conselho Municipal dos Direitos da Criança e do Adolescente e do Conselho Municipal de Assistência Social facultou a realização de uma análise documental nos arquivos desses Conselhos, relativa às entidades assistenciais cadastradas, tais como organizações governamentais, organizações não-governamentais e outros estabelecimentos filantrópicos. Os resultados indicam que, no universo da Assistência Social, a constelação criança/adolescente orbita em torno do astro-rei socioeducativo. Todas as atividades desenvolvidas nas entidades parecem recobertas por esse significantemestre, que conota dimensões pedagógicas e terapêuticas, educativas e corretivas, de vigilância e de prevenção, promovendo controle e normalização.

Diabetes mellitus: razão de prevalências nas diferentes regiões geográficas no Brasil, 2002 2007

Considerando o Diabetes mellitus (DM) como um relevante problema de saúde no Brasil e a importância das estimativas de prevalência para planejamento e estratégias em saúde pública, propôs-se este trabalho com o objetivo de estimar a razão de prevalências do DM nos diferentes estados brasileiros nos períodos de 2002 a 2004 e 2005 a 2007. Trata-se de estudo descritivo, baseado em dados da população brasileira com diagnóstico de DM cadastrada no Sistema de Informação da Atenção Básica (SIAB) junto ao Ministério da Saúde. As taxas de prevalência foram calculadas para o período de 2002 a 2004 e para 2005 a 2007, e posteriormente estimou-se a Razão de Prevalências (R) por ponto e por intervalo de 95% de confiança (IC95%). Observou-se alta prevalência de DM nos estados brasileiros com aumento significativo (R>1; IC95%>1) entre os períodos em todos os estados brasileiros, com destaque para o Distrito Federal (R=1,9800; IC95%=1,97241,9876) e o estado do Maranhão (R=1,5217; IC95%=1,51981,5235). Pode-se concluir que houve aumento significativo na prevalência de DM no Brasil de 2002 a 2007, sinalizando para a necessidade de formulação de estratégias de prevenção e controle da doença.

Análise fenotípica e molecular da produção de biofilmes por estirpes de staphylococcus aureus isoladas de casos de mastite subclínica bovina

Biofilm formation is considered an advantage for Staphylococcus aureus mastitis isolates, facilitating bacterial persistence in the udder. It requires attachment to mammary epithelium, proliferation and accumulation of cells in multilayers and enclosing in a polymeric matrix known as exopolysaccharide. The objective of this study was to evaluate the ability of Staphylococcus aureus isolated from bovine subclinical mastitis for formation of biofilms. A total of 94 Staphylococcus aureus strains obtained from milk samples of cows suffering from subclinical mastitis in dairy herds on two properties in the state of São Paulo were evaluated. These strains were characterized by in vitro biofilm formation, and by the presence of icaA and icaD genes which are responsible for intercellular adhesion. The results revealed that 98.9% of the isolates produced biofilm in vitro by adherence in sterile 96-well "U" bottom polystyrene tissue culture plates; 95.7% of the isolates possessed the icaA and icaD genes. These bacterial isolates biofilm producers may impair eradication of chronic mastitis, rendering antibiotherapy less effective. The detection of biofilm forming ability in mastitis isolates may provide useful information for more adequate therapeutic regimen and for preventive actions in the control of those bacterial isolates in bovine herds.
