THE INTERNATIONAL CLASSIFICATION OF PUBLIC HEALTH NURSING PRACTICES - CIPESC (R): A PEDAGOGICAL TOOL FOR EPIDEMIOLOGICAL STUDIES

The CIPESC (R) is a tool that informs the work of nurses in Public Health and assists in prioritizing their care in practice, management and research. It is also a powerful pedagogical instrument for the qualification of nurses within the Brazilian healthcare system. In the teaching of infectious diseases, using the CIPESC (R) assists in analyzing the interventions by encouraging clinical and epidemiological thinking regarding the health-illness process. With the purpose in mind of developing resources for teaching undergraduate nursing students and encouraging reflection regarding the process of nursing work, this article presents an experimental application of CIPESC (R), using meningococcal meningitis as an example.

Mild Stunting is Associated with Higher Blood Pressure in Overweight Adolescents

Background: Studies have shown that pre/postnatal undernutrition leads to higher risk of non communicable diseases such as diabetes, hypertension and obesity in adulthood. Objetive: To determine whether overweight adolescents with mild stunting [height-for-age Z scores (HAZ) in the range <-1 to >=-2] have higher blood pressure than overweight individuals with normal stature (HAZ >=-1). Methods: Participants were classified as mildly stunted or of normal stature, and further stratified according to body mass index-for-age percentiles as overweight, normal or underweight. Systolic (SBP) and diastolic (DPB) blood pressures were determined according to guidelines, and abdominal fat was analyzed by dual energy X-ray absorptiometry. Results: Mild stunted overweight individuals showed higher DBP values (p=0.001) than their underweight counterparts (69.75 +/- 12.03 and 54.46 +/- 11.24 mmHg, respectively), but similar to those of normal BMI. No differences were found in DBP values of normal, overweight and underweight individuals among the normal stature groups. An increase in SBP (p=0.01) among mild stunted individuals was found when those with overweight were compared to their underweight and normal BMI counterparts (114.70 +/- 15.46, 97.38 +/- 10.87 and 104.72 +/- 12.24 mmHg, respectively). Although no differences were observed in the means of SBP between mild stunting and normal stature groups, a significant intercept was found (p=0.01), revealing higher SBP among stunted individuals. There was a correlation between SBP and abdominal fat (r=0.42, rho=0.02) in the stunted group. Conclusions: Stunted individuals with overweight showed higher SBP than those of normal stature and overweight. These findings confirm that mild stunting increase the risk of future hypertension and alterations are evident at early age. (Arq Bras Cardiol 2012;98(1):6-12)

Antioxidant intake among Brazilian adults - The Brazilian Osteoporosis Study (BRAZOS): a cross-sectional study

Abstract Background Antioxidant nutrient intake and the lesser formation of free radicals seem to contribute to chronic diseases. The aim of the present study was to evaluate the intake profile of the main dietary antioxidants in a representative sample of the adult Brazilian population and discuss the main consequences of a low intake of these micronutrients on overall health. Methods The sample comprised 2344 individuals aged 40 years or older from 150 cities and was based on a probabilistic sample from official data. The research was conducted through in-home interviews administered by a team trained for this purpose. Dietary intake information was obtained through 24-h recall. The Nutrition Data System for Research software program was used to analyze data on the intake of vitamins A, C and E, selenium and zinc, which was compared to Dietary Reference Intakes (DRIs). Differences in intake according to sex, anthropometrics, socioeconomic status and region were also evaluated. The SPSS statistical package (version 13) was used for the statistical analysis. P-values < 0.05 were considered significant. Results Higher proportions of low intake in relation to recommended values were found for vitamin E (99.7%), vitamin A (92.4%) and vitamin C (85.1%) in both genders. Intake variations were found between different regions, which may reflect cultural habits. Conclusion These results should lead to the development of public health policies that encourage educational strategies for improving the intake of micronutrients, which are essential to overall health and prevention of non-communicable diseases.

Doenças crônicas não transmissíveis no Brasil: prioridade para enfrentamento e investigação

As Doenças Crônicas Não Transmissíveis representam a maior carga de morbimortalidade no Brasil. Em 2011, o Ministério da Saúde lançou seu Plano de Ações Estratégicas para o Enfrentamento das Doenças Crônicas Não Transmissíveis, enfatizando ações populacionais para controlar as doenças cardiovasculares, diabetes, câncer e doença respiratória crônica, predominantemente pelo controle do fumo, inatividade física, alimentação inadequada e uso prejudicial de álcool. Apesar da produção científica significativa sobre essas doenças e seus fatores de risco no Brasil, poucos são os estudos de coorte nessa temática. Nesse contexto, o Estudo Longitudinal da Saúde do Adulto (ELSA-Brasil) acompanha 15.105 servidores públicos do País. Seus dados espelham a realidade brasileira de altas prevalências de diabetes e hipertensão e dos fatores de risco. A diversidade das informações produzidas permitirá aprofundar o entendimento causal dessas doenças e subsidiar políticas públicas para seu enfrentamento.

A baixa estatura leve está associada ao aumento da pressão arterial em adolescentes com sobrepeso

FUNDAMENTO: Estudos têm demonstrado que a desnutrição pré/pós-natal leva a um maior risco de doenças não transmissíveis, como diabetes, hipertensão e obesidade na idade adulta. OBJETIVO: Determinar se os adolescentes com sobrepeso e desnutrição leve [escores-Z altura/idade (HAZ) na faixa de <-1 a > -2] têm pressão arterial mais elevada do que os indivíduos com sobrepeso e com estatura normal (HAZ > -1). MÉTODOS: Os participantes foram classificados como de baixa estatura leve ou de estatura normal, e estratificados de acordo com os percentis de massa corporal para a idade, como sobrepeso, peso normal ou abaixo do peso. As pressões arteriais sistólica (PAS) e diastólica (PAD) foram determinadas de acordo com as diretrizes e a gordura abdominal foi analisada por absorciometria de dupla emissão de raios-X. RESULTADOS: Indivíduos com baixa estatura leve e sobrepeso apresentaram valores mais elevados da PAD (p = 0,001) do que suas contrapartes de baixo peso (69,75 ± 12,03 e 54,46 ± 11,24 mmHg, respectivamente), mas semelhantes àqueles com IMC normal. Não foram encontradas diferenças nos valores de PAD em indivíduos normais, indivíduos com sobrepeso e com baixo peso entre os grupos de estatura normal. Foi encontrado um aumento na PAS (p = 0,01) entre os indivíduos com baixa estatura leve quando comparados os indivíduos com sobrepreso com suas contrapartes de baixo peso e IMC normal (114,70 ± 15,46, 97,38 ± 10,87 e 104,72 ± 12,24 mmHg, respectivamente). Embora não tenham sido observadas diferenças nas médias de PAS entre os grupos de baixa estatura leve e estatura normal, foi encontrado um intercepto significativo (p = 0,01), revelando maior PAS entre os indivíduos com baixa estatura leve. Houve correlação entre PAS e gordura abdominal (r = 0,42, ρ = 0,02) no grupo com baixa estatura leve. CONCLUSÃO: Indivíduos de baixa estatura leve com sobrepeso apresentaram maior PAS do que os de estatura normal e sobrepeso. Esses achados confirmam que a baixa estatura leve aumenta o risco futuro de hipertensão e essas alterações são evidentes em indivíduos jovens.

Resultados do monitoramento dos Fatores de risco e Proteção para Doenças Crônicas Não Transmissíveis nas capitais brasileiras por inquérito telefônico, 2008

OBJETIVO: Analisar os fatores de risco e proteção para Doenças Crônicas Não Transmissíveis - DCNT nas capitais do Brasil. METODOLOGIA: Foram analisadas informações provenientes do sistema de vigilância de fatores de risco e proteção para DCNT por inquérito telefônico - VIGITEL, em 2008. A amostra foi composta por 54 mil entrevistas sendo as frequências apresentadas para o conjunto das capitais por sexo, faixa etária e escolaridade. RESULTADOS: O estudo mostrou diferenças na prevalência de fatores de risco e proteção de DCNT entre sexos, idade e escolaridade. Os homens apresentaram maiores frequências de fatores de risco como fumo, excesso de peso, consumo de refrigerantes, carnes com excesso de gordura e bebidas alcoólicas. Os homens praticam mais atividade física no lazer. As mulheres se alimentam melhor e referem mais diagnóstico médico de doenças, como hipertensão arterial, dislipidemia e osteoporose, além de estado de saúde ruim. Em geral, os fatores de risco são mais frequentes na população de menor escolaridade. DISCUSSÃO: Estas informações devem redirecionar a implementação das políticas públicas com foco em um modo de viver mais saudável e escolhas individuais mais adequadas por parte da população adulta brasileira.

NONSPECIFIC INFECTIOUS DISEASES IN PREHISTORIC SAN PEDRO DE ATACAMA, NORTHERN CHILE

The region of San Pedro de Atacama, Northern Chile, has undergone several cultural and social changes after humans settled in Atacama Desert around 500 BC. The Atacameno people experienced the highest degree of social and cultural changes between 400 and 900 AD when they were assimilated into the Tiwanaku trade and political web that influenced most of the Central-Southern Andes. Under the influence of Tiwanaku, San Pedro de Atacama experienced its greatest economic development. Prior analyses of local human skeletal remains have shown a significant increase in the stature of the local population during the same period. In this paper, we investigate the impact of the Tiwanaku influence on the local epidemiological profile using the incidence of periostitis and osteomyelitis as indicators of biological stress. Surprisingly, the best epidemiological condition occurred during the final phase of influence of Tiwanaku (910-960 AD), and not during the apex influence (480-920 AD), as expected by the archaeological context. We suggest that population growth and aggregation may have counteracted the benefits of improved nutrition during the peak Tiwanaku influence. A severe drought occurred between 1,100 and 1,400 AD in Northern Chile. This could also explain the marked increase of bone infections in the post-Tiwanaku period (920-1,240 AD).

Increased IgE serum levels are unrelated to allergic and parasitic diseases in patients with juvenile systemic lupus erythematosus

OBJECTIVE: The aim of this study was to assess the IgE serum levels in juvenile systemic lupus erythematosus patients and to evaluate possible associations with clinical and laboratory features, disease activity and tissue damage. METHODS: The IgE serum concentrations in 69 consecutive juvenile systemic lupus erythematosus patients were determined by nephelometry. IgG, IgM and IgA concentrations were measured by immunoturbidimetry. All patients were negative for intestinal parasites. Statistical analysis methods included the Mann-Whitney, chi-square and Fisher's exact tests, as well as the Spearman rank correlation coefficient. RESULTS: Increased IgE concentrations above 100 IU/mL were observed in 31/69 (45%) juvenile systemic lupus erythematosus patients. The mean IgE concentration was 442.0 +/- 163.4 IU/ml (range 3.5- 9936.0 IU/ml). Fifteen of the 69 patients had atopic disease, nine patients had severe sepsis and 56 patients presented with nephritis. The mean IgE level in 54 juvenile systemic lupus erythematosus patients without atopic manifestations was 271.6 +/- 699.5 IU/ml, and only nine of the 31 (29%) patients with high IgE levels had atopic disease. The IgE levels did not statistically differ with respect to the presence of atopic disease, severe sepsis, nephritis, disease activity, or tissue damage. Interestingly, IgE concentrations were inversely correlated with C4 levels ( r = -0.25, p = 0.03) and with the SLICC/ACR-DI score (r = -0.34, p = 0.005). The IgE concentration was also found to be directly correlated with IgA levels (r = 0.52, p = 0.03). CONCLUSIONS: The present study demonstrated for the first time that juvenile systemic lupus erythematosus patients have increased IgE serum levels. This increase in IgE levels was not related to allergic or parasitic diseases. Our results are in line with the hypothesis that high IgE levels can be considered a marker of immune dysregulation.

Phosphene Thresholds Elicited by Transcorneal Electrical Stimulation in Healthy Subjects and Patients with Retinal Diseases

PURPOSE. To evaluate electrically evoked phosphene thresholds (EPTs) in healthy subjects and in patients with retinal disease and to assess repeatability and possible correlations with common ophthalmologic tests. METHODS. In all, 117 individuals participated: healthy subjects (n = 20) and patients with retinitis pigmentosa (RP, n = 30), Stargardt's disease (STG, n = 14), retinal artery occlusion (RAO, n = 20), nonarteritic anterior ischemic optic neuropathy (NAION, n = 16), and primary open-angle glaucoma (POAG, n = 17). EPTs were determined at 3, 6, 9, 20, 40, 60, and 80 Hz with 5+5-ms biphasic current pulses using DTL electrodes. Subjects were examined twice (test-retest range: 1-6 weeks). An empirical model was developed to describe the current-frequency relationship of EPTs. Visual acuity, visual field (kinetic + static), electrophysiology (RP, RAO, STG: Ganzfeld-electroretinography [ERG]/multifocal-ERG; POAG: pattern-ERG; NAION: VEP), slit-lamp biomicroscopy, fundus examination, and tonometry were assessed. RESULTS. EPTs varied between disease groups (20 Hz: healthy subjects: 0.062 +/- 0.038 mA; STG: 0.102 +/- 0.097 mA; POAG: 0.127 +/- 0.09 mA; NAION: 0.244 +/- 0.126 mA; RP: 0.371 +/- 0.223 mA; RAO: 0.988 +/- 1.142 mA). In all groups EPTs were lowest at 20 Hz. In patients with retinal diseases and across all frequencies EPTs were significantly higher than those in healthy subjects, except in STG at 20 Hz (P = 0.09) and 40 Hz (P = 0.17). Test-retest difference at 20 Hz was 0.006 mA in the healthy group and 0.003-0.04 mA in disease groups. CONCLUSIONS. Considering the fast, safe, and reliable practicability of EPT testing, this test might be used more often under clinical circumstances. Determination of EPTs could be potentially useful in elucidation of the progress of ophthalmologic diseases, either in addition to standard clinical assessment or under conditions in which these standard tests cannot be used meaningfully.

Atmospheric pollution: influence on hospital admissions in paediatric rheumatic diseases

Objective: To investigate the lag structure effects from exposure to atmospheric pollution in acute outbursts in hospital admissions of paediatric rheumatic diseases (PRDs). Methods: Morbidity data were obtained from the Brazilian Hospital Information System in seven consecutive years, including admissions due to seven PRDs (juvenile idiopathic arthritis, systemic lupus erythematosus, dermatomyositis, Henoch-Schonlein purpura, polyarteritis nodosa, systemic sclerosis and ankylosing spondylitis). Cases with secondary diagnosis of respiratory diseases were excluded. Daily concentrations of inhaled particulate matter (PM10), sulphur dioxide (SO2) nitrogen dioxide (NO2), ozone (O-3) and carbon monoxide (CO) were evaluated. Generalized linear Poisson regression models controlling for short-term trend, seasonality, holidays, temperature and humidity were used. Lag structures and magnitude of air pollutants' effects were adopted to estimate restricted polynomial distributed lag models. Results: The total number of admissions due to acute outbursts PRD was 1,821. The SO2 interquartile range (7.79 mu g/m(3)) was associated with an increase of 1.98% (confidence interval 0.25-3.69) in the number of hospital admissions due to outcome studied after 14 days of exposure. This effect was maintained until day 17. Of note, the other pollutants, with the exception of O-3, showed an increase in the number of hospital admissions from the second week. Conclusion: This study is the first to demonstrate a delayed association between SO2 and PRD outburst, suggesting that oxidative stress reaction could trigger the inflammation of these diseases.

Prior history of sexually transmitted diseases in women living with AIDS in Sao Paulo, Brazil

Objectives: To describe the epidemiological profile, risk behaviors, and the prior history of sexually transmitted diseases (STDs) in women living with acquired immunodeficiency syndrome (AIDS). Methods: Cross-sectional study, performed at the Centro de Referencia e Treinamento em DST/AIDS of Sao Paulo. The social, demographic, behavioral, and clinical data such as age, schooling, marital status, age at first sexual intercourse, number of sexual partners, parity, use of drugs, time of HIV diagnosis, CD4 count, and viral load determination were abstracted from the medical records of women living with AIDS who had gynecological consultation scheduled in the period from June 2008 to May 2009. Results: Out of 710 women who were scheduled to a gynecological consultation during the period of the study, 598 were included. Previous STD was documented for 364 (60.9%; 95% CI: 56.9%-64.8%) women. The associated factors with previous STDs and their respective risks were: human development index (HDI) <0.50 (ORaj = 5.5; 95% CI: 2.8-11.0); non-white race (ORaj = 5.2; 95% CI: 2.5-11.0); first sexual intercourse at or before 15 years of age (ORaj = 4.4; 95% CI: 2.3-8.3); HIV infection follow-up time of nine years or more (ORaj = 4.2; 95% CI: 2.3-7.8)]; number of sexual partners during the entire life between three and five partners (ORaj = 2.2; 95% CI: 1.1-4.6), and six or more sexual partners (ORaj = 3.9; 95% CI: 1.9-8.0%); being a sex worker (ORaj = 1.9; 95% CI: 1.1-3.1). Conclusions: A high prevalence of a prior history of STDs in the studied population was found. It is essential to find better ways to access HIV infection prevention, so that effective interventions can be more widely implemented. (C) 2012 Elsevier Editora Ltda. All rights reserved.

JC virus-associated central nervous system diseases in HIV-infected patients in Brazil: clinical presentations, associated factors with mortality and outcome

Introduction: Several presentations of neurologic complications caused by JC virus (JCV) in human immunodeficiency virus (HIV)-infected patients have been described and need to be distinguished from the "classic" form of progressive multifocal leukoencephalopathy (PML). The objectives of this study were: 1) to describe the spectrum and frequency of presentations of JCV-associated central nervous system (CNS) diseases; 2) identify factors associated with in-hospital mortality of patients with JCV-associated CNS disease; and 3) to estimate the overall mortality of this population. Material and methods: This was a retrospective study of HIV-infected patients admitted consecutively for JCV-associated CNS diseases in a referral teaching center in Sao Paulo, Brazil, from 2002 to 2007. All patients with laboratory confirmed JCV-associated CNS diseases were included using the following criteria: compatible clinical and radiological features associated with the presence of JCV DNA in the cerebrospinal fluid. JCV-associated CNS diseases were classified as follows: 1) classic PML; 2) inflammatory PML; and 3) JC virus granule cell neuronopathy (GCN). Results: We included 47 cases. JCV-associated CNS diseases were classified as follows: 1) classic PML: 42 (89%); 2) inflammatory PML: three (6%); and 3) JC virus GCN: four (9%). Nosocomial pneumonia (p = 0.003), previous diagnosis of HIV infection (p = 0.03), and imaging showing cerebellar and/or brainstem involvement (p = 0.02) were associated with in-hospital mortality. Overall mortality during hospitalization was 34%. Conclusions: Novel presentations of JCV-associated CNS diseases were observed in our setting; nosocomial pneumonia, previous diagnosis of HIV infection, and cerebellar and/or brainstem involvement were associated with in-hospital mortality; and overall mortality was high.

Advancing the management of primary immunodeficiency diseases in Latin America: Latin American Society for Immunodeficiencies (LASID) Initiatives

Primary immunodeficiency diseases (PIDD) are associated with significant morbidity and mortality and result in a significant public health burden. This is in part due to the lack of appropriate diagnosis and treatment of these patients. It is critical that governments become aware of this problem and provide necessary resources to reduce this impact on health care systems. Leading physicians in their respective countries must be supported by their own governments in order to implement tools and provide education and thus improve the diagnosis and treatment of PIDD. The Latin American Society of Primary Immunodeficiencies (LASID) has initiated a large number of activities aimed at achieving these goals, including the establishment of a PIDD registry, development of educational programmes and guidelines, and the introduction of a PIDD fellowship programme. These initiatives are positively impacting the identification and appropriate treatment of patients with PIDD in Latin America. Nevertheless, much remains to be done to ensure that every person with PIDD receives proper therapy. (C) 2011 SEICAP. Published by Elsevier Espana, S.L. All rights reserved.

The therapeutic journey of families of children with respiratory diseases in the public health service

This study's purpose was to identify the therapeutic journey of families seeking health care for their children with respiratory diseases. This qualitative study had the participation of parents of children younger than five years old who were hospitalized with respiratory diseases. Path mapping was used as an instrument to collect data, which was analyzed through thematic analysis. The finding indicate that families sought the health services as soon as they perceived symptoms and had access to medical care, however such care was not decisive in resolving their health issues. Even though the families returned to the service at least another three times, the children had to be hospitalized. The attributes of primary health care were not observed in the public health services, while therapeutic encounters had no practical success.
