Organização do trabalho, conflitos e agressões em uma emergência hospitalar na cidade de São Paulo, Brasil

As condições e processos de trabalho penosos dos pronto-socorros somados a elevada demanda frente à capacidade e gravidade dos casos, dificultam as decisões, impactam no atendimento e favorecem conflitos. Trata-se de um estudo de caso, exploratório e qualitativo, utilizou-se dados documentais, entrevistas semiestruturadas e observação do trabalho, especificamente dos porteiros. Objetivou-se verificar como características da organização do trabalho aumentam conflitos e agressões em um pronto-socorro comprometendo os atendimentos. Constatou-se que os porteiros estão na linha de frente e são expostos à pressão dos usuários por atendimento. Para solucionar conflitos, extrapolam regras e procedimentos, realizam tarefas além da sua competência, podendo alterar o fluxo e a qualidade do atendimento. Os arranjos organizacionais desconsideram os porteiros como parte da equipe de cuidados expondo-os a conflitos e agressões. Espera-se contribuir para mudanças, melhorar as relações, a segurança e o fluxo de atendimento.

Awareness and knowledge of HPV, cervical cancer, and vaccines in young women after first delivery in São Paulo, Brazil - a cross-sectional study

Abstract Background The success of HPV vaccination programs will require awareness regarding HPV associated diseases and the benefits of HPV vaccination for the general population. The aim of this study was to assess the level of awareness and knowledge of human papillomavirus (HPV) infection, cervical cancer prevention, vaccines, and factors associated with HPV awareness among young women after birth of the first child. Methods This analysis is part of a cross-sectional study carried out at Hospital Maternidade Leonor Mendes de Barros, a large public maternity hospital in Sao Paulo. Primiparous women (15-24 years) who gave birth in that maternity hospital were included. A questionnaire that included questions concerning knowledge of HPV, cervical cancer, and vaccines was applied. To estimate the association of HPV awareness with selected factors, prevalence ratios (PR) were estimated using a generalized linear model (GLM). Results Three hundred and one primiparous women were included; 37% of them reported that they "had ever heard about HPV", but only 19% and 7%, respectively, knew that HPV is a sexually transmitted infection (STI) and that it can cause cervical cancer. Seventy-four percent of interviewees mentioned the preventive character of vaccines and all participants affirmed that they would accept HPV vaccination after delivery. In the multivariate analysis, only increasing age (P for trend = 0.021) and previous STI (P < 0.001) were factors independently associated with HPV awareness ("had ever heard about HPV"). Conclusions This survey indicated that knowledge about the association between HPV and cervical cancer among primiparous young women is low. Therefore, these young low-income primiparous women could benefit greatly from educational interventions to encourage primary and secondary cervical cancer prevention programs.

Clinical, epidemiological and molecular features of the HIV-1 subtype C and recombinant forms that are circulating in the city of São Paulo, Brazil

Abstract Background The city of Sao Paulo has the highest AIDS case rate, with nearly 60% in Brazil. Despite, several studies involving molecular epidemiology, lack of data regarding a large cohort study has not been published from this city. Objectives This study aimed to describe the HIV-1 subtypes, recombinant forms and drug resistance mutations, according to subtype, with emphasis on subtype C and BC recombinants in the city of São Paulo, Brazil. Study design RNA was extracted from the plasma samples of 302 HIV-1-seropositive subjects, of which 211 were drug-naive and 82 were exposed to ART. HIV-1 partial pol region sequences were used in phylogenetic analyses for subtyping and identification of drug resistance mutations. The envelope gene of subtype C and BC samples was also sequenced. Results From partial pol gene analyses, 239 samples (79.1%) were assigned as subtype B, 23 (7.6%) were F1, 16 (5.3%) were subtype C and 24 (8%) were mosaics (3 CRF28/CRF29-like). The subtype C and BC recombinants were mainly identified in drug-naïve patients (72.7%) and the heterosexual risk exposure category (86.3%), whereas for subtype B, these values were 69.9% and 57.3%, respectively (p = 0.97 and p = 0.015, respectively). An increasing trend of subtype C and BC recombinants was observed (p < 0.01). Conclusion The HIV-1 subtype C and CRFs seem to have emerged over the last few years in the city of São Paulo, principally among the heterosexual population. These findings may have an impact on preventive measures and vaccine development in Brazil.

Custos hospitalares da meningite causada por Streptococcus pneumoniae na cidade de São José dos Campos, São Paulo, Brasil

O conhecimento dos custos hospitalares é de grande importância para os processos de tomada de decisão em saúde pública. O objetivo deste estudo foi estimar os custos hospitalares diretos relacionados à meningite pneumocócica em crianças com até 13 anos (inclusive), na cidade de São José dos Campos, São Paulo, Brasil, de janeiro de 1999 a dezembro de 2008. Foram obtidos dados de prontuários médicos. O cálculo foi realizado pelo método misto de mensuração das quantidades dos itens de custos e atribuição de valor aos itens consumidos (micro-costing e gross-costing). Os valores monetários referem-se a novembro de 2009, sendo expressos em reais. A análise das frequências e médias foi realizada pelo programa Epi Info versão 3.5.1. Foram notificados 41 casos. Os custos hospitalares diretos variaram de R$ 1.277,90 a R$ 19.887,56 (média = R$ 5.666,43), ou seja, 10 a 20 vezes maiores que o custo médio de internações pago pelo SUS. Os custos dos honorários profissionais foram os mais relevantes, seguidos pelos custos dos medicamentos, procedimentos, materiais e exames laboratoriais.

Fatores de risco associados ao desmame em crianças até seis meses de idade no município de São Paulo

OBJETIVO: Avaliar os fatores de risco associados à ausência de aleitamento materno exclusivo (AME) em crianças <6 meses de vida na cidade de São Paulo, em 2008. MÉTODOS: Aplicou-se o questionário do Projeto Amamentação e Municípios-1998 (AMAMUNIC) a pais/responsáveis de crianças <6 meses de idade durante a Campanha Nacional de Vacinação contra Poliomielite. Cálculo da amostra por conglomerados com sorteio em dois estágios. Os fatores analisados foram idade e educação materna, peso de nascimento, sexo, tipo de parto, nascer em Hospital Amigo da Criança, presença de aleitamento materno precoce, uso de chupeta nas últimas 24 horas e mãe trabalhando fora de casa. Análise estatística por regressão logística binária com SPSS, versão 15.0, sendo significante p<0,05. RESULTADOS: Foram realizadas 724 entrevistas, das quais 275 referiram (39,1%) aleitamento materno exclusivo (Grupo I - GI) e 429 (60,9%) sem aleitamento materno exclusivo (Grupo II - GII). Houve diferenças entre os grupos quanto ao uso da chupeta nas últimas 24 horas (GI 32,3 versus GII 59,8%; p<0.001), mães trabalhando fora (GI 12,4 versus GII 24,8%; p<0.001) e idade da criança (GI 74,1±45,3 versus GII 105,8±49,5 dias; p<0,0001).Na análise multivariada, houve associação entre ausência de aleitamento materno exclusivo e uso de chupeta (OR 3,02; IC95% 2,10-4,36), mãe trabalhando fora (OR 2,11; IC95% 1,24-3,57) e idade da criança (OR 1,01; IC95% 1,01-1,02). CONCLUSÕES: O uso da chupeta nas últimas 24 horas associou-se à ausência de AME em crianças menores do que seis meses, seguido pelo trabalho materno fora de casa e pela idade da criança, que são importantes fatores a serem controlados em programas de promoção do aleitamento materno.

Stigma and higher rates of psychiatric re-hospitalization: São Paulo public mental health system

OBJECTIVE: The aim of this study was to assess re-hospitalization rates of individuals with psychosis and bipolar disorder and to study determinants of readmission. METHODS: Prospective observational study, conducted in São Paulo, Brazil. One hundred-sixty-nine individuals with bipolar and psychotic disorder in need of hospitalization in the public mental health system were followed for 12 months after discharge. Their families were contacted by telephone and interviews were conducted at 1, 2, 6 and 12 months post-discharge to evaluate readmission rates and factors related. RESULTSOne-year re-hospitalization rate was of 42.6%. Physical restraint during hospital stay was a risk factor (OR = 5.4-10.5) for readmission in most models. Not attending consultations after discharge was related to the 12-month point readmission (OR = 8.5, 95%CI 2.3-31.2) and to the survival model (OR = 3.2, 95%CI 1.5-7.2). Number of previous admissions was a risk factor for the survival model (OR = 6.6-11.9). Family's agreement with permanent hospitalization of individuals with mental illness was the predictor associated to readmission in all models (OR = 3.5-10.9) and resulted in shorter survival time to readmission; those readmitted were stereotyped as dangerous and unhealthy. CONCLUSIONS: Family's stigma towards mental illness might contribute to the increase in readmission rates of their relatives with psychiatric disorders. More studies should be conducted to depict mechanisms by which stigma increases re-hospitalization rates.

Seroprevalence of toxoplasmosis, toxocariasis and cysticercosis in a rural settlement, São Paulo State, Brazil.

Background: The goal of this study was to estimate the seroprevalence of Toxocara spp., Toxoplasma gondii, and Taenia solium metacestode infection and determine some of the associated risk factors for people living in the Dona Carmen settlement, Pontal of Paranapanema, São Paulo, Brazil. Methods: Serum samples from 194 subjects were tested and participants answered a questionnaire. An enzyme-linked immunosorbent assay (ELISA) system based on Toxocara spp. excretory-secretory antigens obtained from the cultured second-stage larvae of Toxocara canis or vesicular fluid (VF) antigen from Taenia crassiceps metacestode was used to detect anti-Toxocara spp. IgG and IgE and anti-T. solium metacestode, respectively. For cysticercosis, the reactive ELISA samples were assayed by Western blotting using 18 kDa and 14 kDa proteins purified from VF. For T. gondii-specific IgG and IgM antibodies, anti-SAG-1, GRA-1, and GRA-7 epitope specificity was determined by ELISA. Results: Toxoplasma gondii IgG antibodies were found in 102/194 individuals (52.6%) with increased infections in females (P=0.02) and those with US$ ≤ 300monthly income (P=0.01). Positive IgM antibodies were detected in 21/194 individuals (10.8%). Antibodies specific to Toxocara spp. were found in 28/194 subjects (14.4%). All the individuals with Toxocara spp. also had T. gondii-specific IgG antibodies. Taenia solium metacestode antibodies were detected in 11 subjects (5.7%), but none were reactive based on Western blotting. Conclusion: In spite of environmental, educational, and socioeconomic factors favoring parasite infection, the seropositivity rates of T. gondii, Toxocara spp., and T. solium metacestode-specific IgG antibodies are similar to the rates found in studies conducted in different populations in Brazil.

Distribution of hepatitis B virus subgenotype F2a in São Paulo, Brazil

Abstract Background HBV genotype F is primarily found in indigenous populations from South America and is classified in four subgenotypes (F1 to F4). Subgenotype F2a is the most common in Brazil among genotype F cases. The aim of this study was to characterize HBV genotype F2a circulating in 16 patients from São Paulo, Brazil. Samples were collected between 2006 and 2012 and sent to Hospital Israelita Albert Einstein. A fragment of 1306 bp partially comprising HBsAg and DNA polymerase coding regions was amplified and sequenced. Viral sequences were genotyped by phylogenetic analysis using reference sequences from GenBank (n=198), including 80 classified as subgenotype F2a. Bayesian Markov chain Monte Carlo simulation implemented in BEAST v.1.5.4 was applied to obtain the best possible estimates using the model of nucleotide substitutions GTR+G+I. Findings It were identified three groups of sequences of subgenotype F2a: 1) 10 sequences from São Paulo state; 2) 3 sequences from Rio de Janeiro and one from São Paulo states; 3) 8 sequences from the West Amazon Basin. Conclusions These results showing for the first time the distribution of F2a subgenotype in Brazil. The spreading and the dynamic of subgenotype F2a in Brazil requires the study of a higher number of samples from different regions as it is unfold in almost all Brazilian populations studied so far. We cannot infer with certainty the origin of these different groups due to the lack of available sequences. Nevertheless, our data suggest that the common origin of these groups probably occurred a long time ago.

Validação do escore de meningite bacteriana em crianças com pleocitose em São Paulo, Brasil

Introdução. A maioria das crianças com pleocitose tem meningite viral, não bacteriana. O Escore de Meningite Bacteriana (EMB) é uma ferramenta clínica para identificar crianças com pleocitose de muito baixo risco para meningite bacteriana (MB). Crianças são consideradas de muito baixo risco para MB se, de acordo com o EMB, não tiverem nenhum dos cinco parâmetros - presença de convulsões à admissão, neutrófilos no liquor > 1000/mm3, neutrófilos no sangue >10000/mm3, coloração de Gram demonstrando bactérias e proteínas no LCR > 80 mg/dL. Objetivo. Avaliar a performance do EMB para distinguir meningite viral de bacteriana em crianças com pleocitose. Métodos. Foi realizado um estudo de coorte retrospectivo em um departamento de emergência de hospital secundário de ensino. Foram identificadas crianças entre 1 mês e 15 anos incompletos entre 2001 e 2011 com pleocitose (mais de 10 células/mm3 no liquor). Foram calculados sensibilidade, especificidade e valores preditivos positivo e negativo do EMB. Resultados. Foram identificados 497 crianças com meningite, sendo 43 (8,6%; intervalo de confiança [IC] 95% 7-13%) com MB e 454 (91,4%; IC 95% 87-93%) com meningite asséptica. Das 208 crianças de muito baixo risco para MB de acordo com o EMB, nenhuma tinha MB (sensibilidade 100%, IC 95% 92-100%; especificidade 62%, IC 95% 57- 67%; valor preditivo negativo 100%; IC 95% 98-100%). Conclusões. O EMB identificou com acurácia elevada crianças de muito baixo risco para MB. Este modelo pode ser utilizado para ajuda na diferenciação entre MB e meningite viral, principalmente em regiões com cobertura incompleta vacinal para meningococo e pneumococo.
