Adequação do processo de assistência pré-natal entre as usuárias do Sistema Único de Saúde em Juiz de Fora-MG

PURPOSE: to evaluate the adequacy of the prenatal care process offered to users of the Unified Health Care System (SUS) in Juiz de Fora-MG and to compare the municipal services. METHODS: a transversal study with auditing was carried out on the records of 370 pregnant women, selected by systematic sampling among women who carried their pregnancies to term and gave birth using SUS services in the first semester of 2002, with prenatal care given in Juiz de Fora. For statistical analysis the c2 test was used to compare the municipal services (level of significance: 5%). The evaluation followed a three-tiered complementary sequence, using: the utilization of prenatal care (Kessner index: beginning and frequency of care) at level 1; the utilization of prenatal care and basic laboratory tests, according to the Humanization Program of Prenatal Care and Birth (ABO-Rh, hemoglobin/hematocrit, VDRL, glycemia and urinalysis), at level 2; and the utilization of prenatal care, the basic laboratory tests and the obligatory clinical-obstetric procedures during a prenatal visit (assessment of blood pressure, weight, edema, uterine fundal height, gestational age, fetal heart rate and fetal presentation), at level 3. RESULTS: the observed adequacy of the process was only 26.7% (level 1), 1.9% (level 2) and 1.1% (level 3). We also observed a prenatal coverage of 99.04%, an average of 6.4 visits per pregnant woman, and an average gestational age of 17.4 weeks at the time of the first prenatal visit. There were no significant differences between the municipal services. CONCLUSIONS: prenatal care offered to SUS users in Juiz de Fora should be reviewed from a qualitative standpoint, and periodic evaluations as necessary instruments of improvement are recommendable. Managers and professionals should undertake actions aimed at increasing compliance with norms/routines of the program - principally the request/recording of basic complementary tests - and which guarantee increased utilization of prenatal care.

Prevalência de quedas e fatores associados em idosos

OBJECTIVE To estimate the prevalence of falls in elderly individuals and to analyze associated factors. METHODS Cross-sectional study with 420 elderly subjects (aged 60 years or older) living in the city of Juiz de Fora (Southeastern Brazil) in 2010. A household survey was conducted and the occurrence of falls in the 12 previous months was described. For the analysis of factors associated with the outcome, a theoretical determination model with three hierarchical blocks was built. The variables were adjusted among each other within each block; those with level of significance < 0.20 were included in the Poisson regression model and adjusted to the immediately higher level, with 5% significance level. RESULTS The prevalence of falls among the elderly was 32.1% (95%CI: 27.7; 36.9). Among those who experienced falls, 53% had a single fall and 19% had fractures as a consequence. Most of the falls (59%) occurred at the elderly persons home. The occurrence of falls was associated with old age, female sex, need of help for locomotion and self-reported diagnosis of osteoporosis. CONCLUSIONS Falls are frequent among the elderly. Knowledge of the factors associated with the occurrence of this event can aid the development of prevention strategies and adequate health services.OBJETIVO: Estimar la prevalencia de caidas en ancianos y analizar factores asociados. METODOS: Estudio transversal con 420 ancianos (60 anos o mas) residentes en Juiz de Fora, Sureste de Brasil, en 2010. Se realizo pesquisa domiciliaria y se describio la ocurrencia de caida en los ultimos 12 meses. Para analisis de los factores asociados al resultado, se construyo un modelo teorico de determinacion con tres bloques jerarquizados. Las variables fueron ajustadas entre si dentro de cada bloque; las que presentaron nivel de significancia < 0,20 fueron incluidas en el modelo de regresion de Poisson y ajustadas al nivel superior al de cada una, con el nivel de 5% de significancia. RESULTADOS: La prevalencia de caidas entre los ancianos fue de 32,1% (IC95% 27,7;36,9). Entre aquellos que sufrieron caida, 53% tuvieron una unica caida y 19% tuvieron fractura como consecuencia. La mayor parte de las caidas (59%) ocurrio en el domicilio del anciano. La ocurrencia de caidas se asocio con edad avanzada, sexo femenino, necesidad de auxilio para locomocion y diagnostico auto-referido de osteoporosis. CONCLUSIONES: Las caidas son frecuentes entre ancianos. El conocimiento de los factores asociados a la ocurrencia de este evento puede auxiliar en la elaboracion de estrategias de prevencion y servicios de salud adecuados.

Prevalência da doença renal crônica nos estágios 3, 4 e 5 em adultos

INTRODUCTION: Strategies that optimize early diagnosis of chronic kidney disease (CKD) are paramount to decrease progression of the disease and the burden of patients needing renal replacement therapy. OBJECTIVE: The aim of this study was to determine the prevalence of CKD stage 3, 4 and 5 in people submitted to dosage of serum creatinine due to different causes, employing a dataset from a private laboratory of the city of Juiz de Fora comprising the years 2004 and 2005. METHODS: Diagnosis and staging of CKD were based upon glomerular filtration rate (GFR) estimated from serum creatinine as recommended by the KDOQI of the National Kidney Foundation and the Brazilian Society of Nephrology. RESULTS: Prevalence of CKD stage 3, 4 and 5 was of 9.6%, with 12.2%, 5.8%, 25.2% and 3.7% among women, men, people >60 and < 60 years of age, respectively. CONCLUSION: Prevalence of CKD found in our study may not only be interpreted as an epidemiologic indicator, but also discloses an alternative operational strategy to identify the disease. Furthermore it supports a proposal to include the estimation of GFR from serum creatinine in the laboratory report as an important and simple tool for early diagnosis of CKD.

Oportunidades do ambiente domiciliar para o desenvolvimento motor

OBJETIVO: Avaliar as oportunidades presentes no ambiente domiciliar para o desenvolvimento motor de lactentes. METODOS: Estudo epidemiologico de base populacional, transversal, realizado com 239 lactentes com idade entre tres e 18 meses, residentes no municipio de Juiz de Fora, MG, em 2010. Os participantes foram selecionados por amostragem aleatoria estratificada, conglomerada, em multiplos estagios. Para avaliar a qualidade e quantidade de estimulo motor no ambiente domiciliar foi utilizado o instrumento Affordance in the Home Environment for Motor Development - Infant Scale. Procedeu-se a analise bivariada com aplicacao do teste qui-quadrado, seguida de regressao logistica multinomial para verificar a associacao entre as oportunidades presentes no domicilio e fatores biologicos, comportamentais, demograficos e socioeconomicos. RESULTADOS: As oportunidades de estimulacao ambiental foram relativamente baixas. Na analise bivariada, para a faixa etaria de tres a nove meses, foi encontrada associacao com os fatores: ordem de nascimento (p = 0,06), classificacao socioeconomica (p = 0,08), renda mensal (p = 0,06) e renda per capita (p = 0,03). No modelo de regressao, prevaleceu a classificacao socioeconomica (RC = 7,46; p = 0,03). Para a faixa etaria de dez a 18 meses, os fatores associados, na analise bivariada, foram: estado civil materno (p < 0,01), convivio da crianca com o pai (p = 0,08), chefe da familia (p = 0,04), numero de pessoas no domicilio (p = 0,05), escolaridade materna (p < 0,01) e paterna (p < 0,01), classificacao socioeconomica (p < 0,01) e renda per capita (p = 0,03). No modelo de regressao, o estado civil materno (RC = 4,83; p = 0,02), escolaridade materna (RC = 0,29; p = 0,03) e paterna (RC = 0,33; p = 0,04) permaneceram associados as oportunidades de estimulacao ambiental. CONCLUSOES: A uniao estavel dos pais, maior escolaridade materna e paterna e maior nivel economico foram os fatores associados as melhores oportunidades de estimulacao motora no lar.

Perfil imuno-histoquímico e variáveis clinicopatológicas no câncer de mama

OBJECTIVE: To describe the main characteristics of women with breast cancer, according to the immunohistochemical profile. METHODS: The population comprised a hospital cohort, consisting of women diagnosed with breast cancer between 2003 and 2005 (n = 601) and treated at a referral center for cancer care in Juiz de Fora, MG, Brazil. Only 397 women who had complete immunohistochemistry analysis were selected. To define the groups according to the immunohistochemical profile, the assessment of estrogen and progesterone receptors, Ki-67 cell proliferation index, and overexpression of human epidermal growth factor receptor 2 (HER2) was chosen. According to the different phenotypes, five subtypes were defined: luminal A, luminal B HER2 negative, luminal B HER2 positive, triple negative, and HER2 overexpression. RESULTS: Most patients were white (80.7%) and post-menopausal (64.9%), with a mean age of 57.4 years (± 13.5). At diagnosis, 57.5% had tumor size > 2.0 cm, and 41.7% had lymph node involvement. The most common subtypes were luminal B - HER2 negative (41.8%) and triple negative (24.2%). In the luminal A subtype, 72.1% of patients were post-menopausal, while the highest percentage of premenopausal women were observed in the luminal B - HER2 positive and triple negative subtypes (45.2% and 44.2%, respectively). A higher frequency of tumors > 2.0 cm and lymph node involvement was observed in triple negative and HER2 positive subtypes. CONCLUSION: This study allowed the distribution assessment of the main clinical and pathological characteristics and those related to health services in a cohort of Brazilian women with breast cancer, according to the immunohistochemical tumor subtypes.

Avaliação da efetividade dos cursos preparatórios para residência médica

In Brazil there are not enough vacancies for Medical Residency (MR) and a very high competition for vacancies in certain specialties and regions. This favors the establishment of Preparatory Courses (PCs) for MR tests. Medical students have been increasingly neglecting their curricular activities for en rolling in these Preparatory Courses. For evaluating the effectiveness of these courses, a questionnaire was applied to the candidates for MR at the University Hospital of Federal University of Juiz de Fora. 74.7% from the 368 applicants agreed to participate in the study, most of which (72%) were frequenting PCs. There was no significant difference in the rate of approval among the candidates who had prepared themselves in PCs and those who did not. On the other hand, the average grade of the candidates that took PCs was 4.07 points higher (66.89 versus 62.82, p < 0.05). It is concluded that in the traditional evaluation model, whose theoretical test corresponds to 90% of the final grade, the preparation of the students who took PCs is more effective, valuing memorization above medical abilities. Thus, the 50/50 model, in which the practical test corresponds to 50% of the final grade, can be considered an adequate proposal.

Ações voltadas para o tabagismo: análise de sua implementação na Atenção Primária à Saúde

This survey examined the status of the implementation of policies for tobacco control in a medium-sized municipality through an assessment of actions recommended by the National Tobacco Control Program (NTCP) promoted by Primary Health Care (PHC) units. The coordinator of the local NTCP and professionals from 44 PHC units of Juiz de Fora in the state of Minas Gerais were interviewed, between May and July 2011. It was observed that the actions of treatment and health promotion were being duly executed, the highlight being the training of professionals to implement treatment in PHC. In 40.9%, there is the provision of treatment for smokers, and in 88.6% the actions are concentrated in activities in waiting rooms, groups and individual consultations. Limitations identified are probably not restricted to the municipality, such as inadequate structuring of units, high turnover, the varying degree of involvement of professionals in implementing the service and also the lack of mechanisms to enable them to implement and give continuity to care among their other responsibilities. The major challenge for tobacco control is to conduct intersectoral actions and in primary health care. The results can serve for the formulation of strategic health actions in other parts of the country.
