Este estudo teve como objetivo identificar e analisar as consequências objetivas e subjetivas de uma gravidez em adolescentes, considerando-se as diferenças socioeconômicas entre elas. Foi realizado um estudo exploratório, qualitativo, com 20 adolescentes que deram à luz entre junho de 2009 a junho de 2010. O instrumento de coleta de dados foi elaborado na forma de uma entrevista semiestruturada e para a verificação dos dados utilizou-se a análise de conteúdo. Entre os resultados observou-se que, apesar de as famílias com renda mais baixa terem em um primeiro momento aceitado melhor a gravidez, o maior impacto também ocorreu entre estas famílias, principalmente quanto ao adiamento ou comprometimento dos projetos educacionais, menor chance de qualificação profissional e dependência financeira absoluta da família. Os métodos contraceptivos eram conhecidos, mas não utilizados, o que demonstra o desafio de alcançar estratégias de prevenção para este público-alvo, com o qual os programas desenvolvidos, além de informativos, devem abordar as vivências emocionais, sociais e culturais.

Introductions e objective: To compare portable ultrasound (US) and bioimpedance analysis (BIA) with skinfolds (SF) to estimate body fat percentage in adults. Methods: 195 military men were assessed and they had their weight, height, body fat by bioimpedance, skinfold in 9 points and ultrasound (US) collected. linear regression was used for the development of a new equation for body fat percentage estimation in young adults (males). results: The group had mean age of 23.07 ± 7.55 years and height and weight with mean and standard deviation of 72.65 ± 10.40 kg, 1.74 ± 0.06 meters, respectively. Comparing the results between the US and SF, there was significant correlation for all points evaluated, with the thigh skinfold presenting the highest correlation, followed by the chest one. When the three methods are compared, the US presented better correlation with the BIA than with SF. A new equation for estimation of fat percentage by US can hence be proposed. Conclusions: It was noticed that in the studied population, US and BIA can estimate the body fat percentage with good correlations with the SF method.

A tuberculose, definida por alguns como a 'calamidade negligenciada, é ainda um importante problema de saúde pública. Para tentar melhorar os resultados no seu enfrentamento, as ações foram descentralizadas para a Atenção Primária à Saúde (APS), o que vem demandando uma nova orientação na Estratégia de Saúde da Família (ESF). Esta pesquisa teve como objetivo analisar a evolução da Estratégia de Saúde da Família (ESF) no município de Curitiba entre os anos de 2000 a 2009 e seus reflexos sobre os casos de Tuberculose. Como metodologia utilizou-se o estudo Ecológico tipo agregado de base territorial longitudinal de séries temporais. A coleta de dados foi realizada no período de outubro de 2010 a julho de 2011. Como principais resultados verificou-se um aumento expressivo de 127,63% no número de Equipes de Saúde da Família, com um aumento da cobertura em 76,28%. Existiu também uma preocupação com relação à capacitação continuada destas equipes o que repercutiu de forma positiva no aumento de exames para diagnóstico realizado, redução do número de casos novos, redução da proporção de abandono do tratamento e da taxa de mortalidade relacionada a tuberculose. Pelo estudo realizado percebe-se uma correção no direcionamento das ações de controle da Tuberculose no município de Curitiba.

ObjectivesThe purpose of this study was to: a) determine the nutritional status of Brazilian adolescents, and; b) present a skinfold thickness model (ST) to estimate body fat developed with Brazilian samples, using dual energy x-ray absorptiometry (DXA) as reference method.MethodsThe main study group was composed of 374 adolescents, and further 42 adolescents for the validation group. Weight, height, waist circumference measurements, and body mass index (BMI) were collected, as well as nine ST–biceps (BI), triceps (TR), chest (CH), axillary (AX) subscapularis (SB), abdominal (AB), suprailiac (SI), medial thigh (TH), calf (CF), and fat percentage (%BF) obtained by DXA.ResultsThe prevalence of overweight in adolescents was 20.9%, and obesity 5.8%. Regression analysis through ordinary least square method (OLS) allowed obtainment of three equations with values of R2 = 0.935, 0.912 and 0.850, standard error estimated = 1.79, 1.78 and 1.87, and bias = 0.06, 0.20 and 0.05, respectively.Conclusionthe innovation of this study lies in presenting new regression equations for predicting body fat in Southern Brazilian adolescents based on a representative and heterogeneous sample from DXA.

ResumoOs profissionais de saúde estão expostos a uma série de riscos no ambiente hospitalar, dentre os quais merece destaque o risco biológico. Esta pesquisa teve como objetivo identificar os fatores de risco para acidentes com material perfurocortantes e analisar as principais causas referidas. Trata-se de estudo exploratório de caráter retrospectivo, com uma amostra composta por 100 acadêmicos de enfermagem, que já exerciam a profissão no nível técnico e tivessem sofrido algum tipo de acidente com materiais perfurocortantes. Constatou-se que 41% dos acidentes ocorreram em hospitais de grande porte, no turno matutino, sendo a UTI o ambiente com maior prevalência de acidentes, e os objetos que mais causaram acidentes foram as agulhas de seringas. As causas apontadas como possíveis fatores de risco para os acidentes indicam a importância da implementação da Política Nacional de Educação Permanente em Saúde (PNEPS), a utilização de EPIs e as precauções-padrão. Palavras AbstractHealth care professionals are exposed to a number of risks in hospital environment among which biological risk should be highlighted. This research aimed to identify risk factors of accidents with sharp instruments and analyze the main causes mentioned. This is a retrospective exploratory study with a sample of one hundred nursing students already working at a technical level and who had already suffered some sort of accident with sharp instruments. The analysis of the results showed that 41% of the accidents occurred in large hospitals and in the morning shift, the ICU environment was the one with greater prevalence of accidents and the objects that caused most accidents were syringe needles. The causes identified as possible risk factors of accidents indicate the importance of implementing the National Policy on Permanent Education in Health (PNEPS), of using PPE and of the standard precautions.

BackgroundThere are several ways to measure the respiratory system, among them inductance plethysmography and three-dimensional kinematic analysis, methods of high cost and difficult transportability. The objective of this study was to correlate respiratory volumes obtained by spirometry standard equipment with a biomechanical model photogrammetric analysis of adolescents.MethodsWe evaluated 50 subjects of both genders, aged between 14 and 17 years old, excluding those with respiratory obstruction or restriction. Stickers with markers, there was a five-point mapping for anatomical modeling and photogrammetry, with each evaluated in supine position, was sought to test the Forced Vital Capacity (FVC). The test was filmed and repeated three times. Images of the films were extracted for the moment of maximum exhalation and inhalation of proof with better breathing. With the use of a commercial software, defined the respiratory volumes to the thorax and abdomen.ResultsThe photogrammetric analysis has found values strongly correlated with the spirometric measurements of FVC (0.812), forced expiratory volume in one second (FEV1 – 0.708), Peak Expiratory Flow (PEF – 0.762) in addition to post test performed Inspiration (IP- 0.816). There was a higher ventilatory mobility for boys than girls for Lower Chest and Lower and Upper Abdomen. It was possible to reach a regression R2 = 0.866 for proof of FVC and R2 = 0.776 for IP with the use of photogrammetry, presenting a standard error of 0.353 and 0.451, respectively.ConclusionsPhotogrammetry can be used to study thoracoabdominal movements by applying analytical two-dimensional and three-dimensional images acquired using a video camera being, applicable and reproducible.
