Consulta ginecológica sob a ótica de estudantes do ensino médio do Rio de Janeiro, RJ

OBJETIVO: Analisar diferenças socioculturais e percepções sobre a consulta ginecológica por adolescentes. MÉTODOS: Estudo transversal com 418 alunas do ensino médio de três escolas de diferentes perfis, localizadas na cidade do Rio de Janeiro, RJ, em 2010. Aplicou-se questionário estruturado, abordando características sociodemográficas, comportamento sexual e avaliação da consulta ginecológica. Utilizou-se o teste de Qui-quadrado (Yates) e o t de Student, adotando-se p < 0,05. RESULTADOS: Alunas dos colégios privado e público apresentaram perfis semelhantes e diferiram daquelas da rede pública estadual que tiveram nível socioeconômico mais baixo, menor escolaridade dos responsáveis, predominância da raça negra, maior número de parceiros, gestações e histórico de violência sexual. As médias de idades da menarca e sexarca foram semelhantes entre as estudantes e a primeira consulta ginecológica foi significativamente mais tardia nas alunas da rede estadual. A maioria referiu conhecimento sobre anticoncepção e doenças sexualmente transmissíveis, porém pequena parte obteve essas orientações na consulta. As estudantes manifestaram desejo de que o profissional investisse mais tempo, paciência e disponibilidade no atendimento. CONCLUSÕES: O atendimento ginecológico na adolescência é insatisfatório segundo a avaliação das adolescentes estudadas. As usuárias dos serviços privados submetem-se à consulta ginecológica em idade mais precoce do que aquelas que têm acesso apenas à rede pública. É necessário criar mecanismos que facilitem o acesso e a adesão desse grupo etário à rotina preventiva ginecológica.

Inquerito por telefone: pesos de pos-estratificacao para corrigir vicios de baixa cobertura em Rio Branco, AC

OBJETIVO: Analisar efeitos do uso de pesos de pós-estratificação para corrigir vícios decorrentes da baixa cobertura de domicílios com telefone. MÉTODOS: Comparação dos resultados levantados pelo Inquérito Domiciliar com o Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (Vigitel), em Rio Branco, AC, 2007, cuja cobertura era de 40% de telefonia fixa. O vício potencial do Vigitel foi expresso pela diferença entre as prevalências do Vigitel e do Inquérito Domiciliar, calculada a raiz quadrática do erro quadrático médio como medida de acurácia da estimativa. RESULTADOS: O procedimento de ponderação do Vigitel corrigiu o vício potencial nas prevalências de consumo de frutas, legumes e verduras, de carnes com gordura visível, o ser fumante, a autoavaliação do estado de saúde ruim e da morbidade referida de colesterol ou triglicéride. O procedimento adotado pelo Vigitel não reduziu o vício nas prevalências da prática de atividade física no tempo livre e de morbidade referida de asma, bronquite asmática, bronquite crônica ou enfisema. CONCLUSÕES: É necessário o uso de métodos alternativos de ponderação e a estratégia de seleção de variáveis externas para construção de pesos de pós-estratificação que minimizem o vício potencial das estimativas das variáveis decorrentes da baixa cobertura de domicílios com telefone fixo.

Homicídios e disputas territoriais nas favelas do Rio de Janeiro

OBJETIVO : Avaliar o risco de homicídios em favelas do Rio de Janeiro, considerando as disputas territoriais em curso na cidade. MÉTODOS : O estudo baseou-se em dados de mortalidade por homicídios na cidade do Rio de Janeiro, de 2006 a 2009. Foram avaliados os riscos em favelas e seus entornos, em função da sua localização e do domínio por grupos armados e tráfico de drogas. Foram empregados métodos e conceitos da geografia e etnografia, com as abordagens de observação participante, entrevistas e análise de dados secundários de saúde. RESULTADOS : As taxas de mortalidade por homicídios no interior das favelas foram equivalentes ou mesmo menores que o restante da cidade, mas consideravelmente maiores nos arredores das favelas, sobretudo em zonas de conflito entre domínios armados rivais. CONCLUSÕES : A presença do tráfico armado em zonas estratégicas da cidade aumenta as taxas de mortalidade por violência e promove a “ecologia do perigo” no entorno de favelas.

Trypanosoma cruzi strains from triatomine collected in Bahia and Rio Grande do Sul, Brazil

OBJECTIVE Collection of triatomines in domestic, peridomestic and sylvatic environments in states of Bahia and Rio Grande do Sul, Northeastern and Southern Brazil respectively, and isolation of Trypanosoma cruzi strains. METHODS First, the captured triatomines were identified using insect identification keys, then their intestinal content was examined by abdominal compression, and the samples containing trypanosomatid forms were inoculated in LIT medium and Swiss mice. RESULTS Six triatomine species were collected in cities in Bahia, namely Panstrongylus geniculatus (01), Triatoma melanocephala (11), T. lenti (94), T. pseudomaculata (02), T. sherlocki (26) and T. sordida (460), and two in cities in Rio Grande do Sul, namely T. circummaculata (11) and T. rubrovaria (115). Out of the specimens examined, T. cruzi was isolated from 28 triatomine divided into four different species: T. melanocephala (one), T. lenti (one), T. rubrovaria (16) and T. sordida (10). Their index of natural infection by T. cruzi was 6.4%. CONCLUSIONS The isolation of T. cruzi strains from triatomines found in domestic and peridomestic areas shows the potential risk of transmission of Chagas disease in the studied cities. The maintenance of those T. cruzi strains in laboratory is intended to promote studies that facilitate the understanding of the parasite-vector-host relationship.

Senses of body image in adolescents in elementary school

OBJECTIVE To comprehend the perception of body image in adolescence. METHODS A qualitative study was conducted with eight focus groups with 96 students of both sexes attending four public elementary school institutions in the city of Rio de Janeiro, Southeastern Brazil, in 2013. An interview guide with questions about the adolescents’ feelings in relation to: their bodies, standards of idealized beauty, practice of physical exercise and sociocultural influences on self-image. In the data analysis we sought to understand and interpret the meanings and contradictions of narratives, understanding the subjects’ context and reasons and the internal logic of the group. RESULTS Three thematic categories were identified. The influence of media on body image showed the difficulty of achieving the perfect body and is viewed with suspicion in face of standards of beauty broadcast; the importance of a healthy body was observed as standards of beauty and good looks were closely linked to good physical condition and result from having a healthy body; the relationship between the standard of beauty and prejudice, as people who are not considered attractive, having small physical imperfections, are discriminated against and can be rejected or even excluded from society. CONCLUSIONS The standard of perfect body propagated by media influences adolescents’ self-image and, consequently, self-esteem and is considered an unattainable goal, corresponding to a standard of beauty described as artificial and unreal. However, it causes great suffering and discrimination against those who do not feel they are attractive, which can lead to health problems resulting from low self-esteem.

Profile and follow-up of patients with tuberculosis in a priority city in Brazil

OBJECTIVE To analyze the cases of tuberculosis and the impact of direct follow-up on the assessment of treatment outcomes.METHODS This open prospective cohort study evaluated 504 cases of tuberculosis reported in the Sistema de Informação de Agravos de Notificação (SINAN – Notifiable Diseases Information System) in Juiz de Fora, MG, Southeastern Brazil, between 2008 and 2009. The incidence of treatment outcomes was compared between a group of patients diagnosed with tuberculosis and directly followed up by monthly consultations during return visits (287) and a patient group for which the information was indirectly collected (217) through the city’s surveillance system. The Chi-square test was used to compare the percentages, with a significance level of 0.05. The relative risk (RR) was used to evaluate the differences in the incidence rate of each type of treatment outcome between the two groups.RESULTS Of the outcomes directly and indirectly evaluated, 18.5% and 3.2% corresponded to treatment default and 3.8% and 0.5% corresponded to treatment failure, respectively. The incidence of treatment default and failure was higher in the group with direct follow-up (p < 0.05) (RR = 5.72, 95%CI 2.65;12.34, and RR = 8.31, 95%CI 1.08;63.92, respectively).CONCLUSIONS A higher incidence of treatment default and failure was observed in the directly followed up group, and most of these cases were neglected by the disease reporting system. Therefore, effective measures are needed to improve the control of tuberculosis and data quality.

Prevalence of hepatitis C virus in Brazil’s inmate population: a systematic review

OBJECTIVE To estimate the prevalence of hepatitis C virus infection in Brazil’s inmate population.METHODS Systematic review on hepatitis C virus infection in the inmate population. Brazilian studies published from January 1, 1989 to February 20, 2014 were evaluated. The methodological quality of the studies was assessed using a scale of 0 to 8 points.RESULTS Eleven eligible studies were analyzed and provided data on hepatitis C virus infection among 4,375 inmates from seven states of Brazil, with a mean quality classification of 7.4. The overall hepatitis C virus prevalence among Brazilian inmates was 13.6% (ranging from 1.0% to 41.0%, depending on the study). The chances of inmates being seropositive for hepatitis C virus in the states of Minas Gerais (MG), Sergipe (SE), Mato Grosso do Sul (MS), Rio Grande do Sul (RS), Goiás (GO) and Espirito Santo (ES) were 84.0% (95%CI 0.06;0.45), 92.0% (95%CI 0.04;0.13), 88.0% (95%CI 0.09;0.18), 74.0% (95%CI 0.16;0.42), 84.0% (95%CI 0.08;0.31) and 89.0% (95%CI 0.01;0.05) respectively, lower than that observed in the Sao Paulo state (seroprevalence of 29.3%). The four studies conducted in the city of Sao Paulo revealed a lower prevalence in more recent studies compared to older ones.CONCLUSIONS The highest prevalence of hepatitis C virus infection in Brazil’s inmate population was found in Sao Paulo, which may reflect the urban diversity of the country. Despite Brazilian studies having good methodological quality to evaluate the prevalence of the hepatitis C virus, they are scarce and lack data on risk factors associated with this infection, which could support decisions on prevention and implementation of public health policies for Brazilian prisons.

Maternal mental health and nutritional status of six-month-old infants

ABSTRACT OBJECTIVE To analyze if maternal mental health is associated with infant nutritional status at six month of age. METHODS A cross-sectional study with 228 six-month-old infants who used primary health care units of the city of Rio de Janeiro, Southeastern Brazil. Mean weight-for-length and mean weight-for-age were expressed in z-scores considering the 2006 World Health Organization reference curves. Maternal mental health was measured by the 12-item General Health Questionnaire. The following cutoff points were used: ≥ 3 for common mental disorders, ≥ 5 for more severe mental disorders, and ≥ 9 for depression. The statistical analysis employed adjusted linear regression models. RESULTS The prevalence of common mental disorders, more severe mental disorders and depression was 39.9%, 23.7%, and 8.3%, respectively. Children of women with more severe mental disorders had, on average, a weight-for-length 0.37 z-scores lower than children of women without this health harm (p = 0.026). We also observed that the weight-for-length indicator of children of depressed mothers was, on average, 0.67 z-scores lower than that of children of nondepressed women (p = 0.010). Maternal depression was associated with lower mean values of weight-for-age z-scores (p = 0.041). CONCLUSIONS Maternal mental health is positively related to the inadequacy of the nutritional status of infants at six months.

Readmission of older patients after hospital discharge for hip fracture: a multilevel approach

ABSTRACT OBJECTIVE To identify individual and hospital characteristics associated with the risk of readmission in older inpatients for proximal femoral fracture in the period of 90 days after discharge. METHODS Deaths and readmissions were obtained by a linkage of databases of the Hospital Information System of the Unified Health System and the System of Information on Mortality of the city of Rio de Janeiro from 2008 to 2011. The population of 3,405 individuals aged 60 or older, with non-elective hospitalization for proximal femoral fracture was followed for 90 days after discharge. Cox multilevel model was used for discharge time until readmission, and the characteristics of the patients were used on the first level and the characteristics of the hospitals on the second level. RESULTS The risk of readmission was higher for men (hazard ratio [HR] = 1.37; 95%CI 1.08–1.73), individuals more than 79 years old (HR = 1.45; 95%CI 1.06–1.98), patients who were hospitalized for more than two weeks (HR = 1.33; 95%CI 1.06-1.67), and for those who underwent arthroplasty when compared with the ones who underwent osteosynthesis (HR = 0.57; 95%CI 0.41–0.79). Besides, patients admitted to state hospitals had lower risk for readmission when compared with inpatients in municipal (HR = 1.71; 95%CI 1.09–2.68) and federal hospitals (HR = 1.81; 95%CI 1.00–3.27). The random effect of the hospitals in the adjusted model remained statistically significant (p < 0.05). CONCLUSIONS Hospitals have complex structures that reflect in the quality of care. Thus, we propose that future studies may include these complexities and the severity of the patients in the analysis of the data, also considering the correlation between readmission and mortality to reduce biases.

Difficulties in access and estimates of public beds in intensive care units in the state of Rio de Janeiro

ABSTRACT OBJECTIVE To estimate the required number of public beds for adults in intensive care units in the state of Rio de Janeiro to meet the existing demand and compare results with recommendations by the Brazilian Ministry of Health. METHODS The study uses a hybrid model combining time series and queuing theory to predict the demand and estimate the number of required beds. Four patient flow scenarios were considered according to bed requests, percentage of abandonments and average length of stay in intensive care unit beds. The results were plotted against Ministry of Health parameters. Data were obtained from the State Regulation Center from 2010 to 2011. RESULTS There were 33,101 medical requests for 268 regulated intensive care unit beds in Rio de Janeiro. With an average length of stay in regulated ICUs of 11.3 days, there would be a need for 595 active beds to ensure system stability and 628 beds to ensure a maximum waiting time of six hours. Deducting current abandonment rates due to clinical improvement (25.8%), these figures fall to 441 and 417. With an average length of stay of 6.5 days, the number of required beds would be 342 and 366, respectively; deducting abandonment rates, 254 and 275. The Brazilian Ministry of Health establishes a parameter of 118 to 353 beds. Although the number of regulated beds is within the recommended range, an increase in beds of 122.0% is required to guarantee system stability and of 134.0% for a maximum waiting time of six hours. CONCLUSIONS Adequate bed estimation must consider reasons for limited timely access and patient flow management in a scenario that associates prioritization of requests with the lowest average length of stay.

Occurrence of Campylobacter jejuni in dog faeces from the streets of a Southern Chilean city

Dog faeces collected from the streets of a southern Chilean city were cultured on selective media for thermophilic Campylobacters. Campylobacter jejuni (biotype 1) was isolated from 53 (35.3%) of 150 samples. The use of an enrichment medium enhanced in 20.8% the isolation rate of this bacteria.

Seroepidemiology of hepatitis a and b in two urban communities of Rio de Janeiro, Brazil

Hepatitis B markers were determined in 397 individuals from Niterói and 680 from Nova Iguaçu and prevalences of 9.1% (1.0% of HBsAg and 8.1% of anti HBs) and 11.1% (1.8% of HBsAg and 9.3% of antiHBs) were found, respectively. The comparative prevalence of both markers in relation to age showed a higher prevalence of HBsAg in the group 21-50 years old. Considering the antiHBs antibody, it was demostrated a gradual increase with age, reaching 14.9% in Niterói and 29.1% in Nova Iguaçu in individuals over 51 years old. For hepatitis A, in 259 samples from Niterói, equally distributed by age groups, an overall prevalence of 74.5% of anti-HAV antibodies was found. This prevalence increases gradually reaching 90.0% at age over thirty. In 254 samples from Nova Iguaçu analysed, a prevalence of 90.5% of antibodies was encountered when the same criteria of distribution of samples were used. This level of prevalence reached 90.0% already in the age over ten years old. The tests were performed by enzyme immunoassay with reagents prepared in our laboratory.
