Narrowing socioeconomic inequality in child stunting: the Brazilian experience, 1974–2007

Objective To assess trends in the prevalence and social distribution of child stunting in Brazil to evaluate the effect of income and basic service redistribution policies implemented in that country in the recent past. Methods The prevalence of stunting (height-for-age z score below \22122 using the Child Growth Standards of the World Health Organization) among children aged less than 5 years was estimated from data collected during national household surveys carried out in Brazil in 1974\201375 (n = 34 409), 1989 (n = 7374), 1996 (n = 4149) and 2006\201307 (n = 4414). Absolute and relative socioeconomic inequality in stunting was measured by means of the slope index and the concentration index of inequality, respectively. Findings Over a 33-year period, we documented a steady decline in the national prevalence of stunting from 37.1 per cent to 7.1 per cent. Prevalence dropped from 59.0 per cent to 11.2 per cent in the poorest quintile and from 12.1 per cent to 3.3 per cent among the wealthiest quintile. The decline was particularly steep in the last 10 years of the period (1996 to 2007), when the gaps between poor and wealthy families with children under 5 were also reduced in terms of purchasing power; access to education, health care and water and sanitation services; and reproductive health indicators.Conclusion In Brazil, socioeconomic development coupled with equity-oriented public policies have been accompanied by marked improvements in living conditions and a substantial decline in child undernutrition, as well as a reduction of the gap in nutritional status between children in the highest and lowest socioeconomic quintiles. Future studies will show whether these gains will be maintained under the current global economic crisis

Mudanças no âmbito da testagem anti-HIV no Brasil entre 1998 e 2005

OBJETIVO: Analisar mudanças na realização de teste anti-HIV, as razões alegadas entre as pessoas que foram ou não testadas e o recebimento de aconselhamento. MÉTODOS: Estudos transversais conduzidos com homens e mulheres de 16 a 65 anos, com amostras representativas do Brasil urbano em 1998 (n=3.600) e 2005 (n=5.040). Características sociodemográficas, sexuais, reprodutivas e de experiências de vida e saúde foram consideradas na análise. A avaliação das possíveis diferenças nas distribuições das variáveis baseou-se nos testes qui-quadrado de Pearson e F design-based (±<5%). RESULTADOS: Em 1998, 20,2% dos entrevistados haviam realizado o teste e 33,6% em 2005. Foram testadas 60% das mulheres na faixa 25-34 anos, mas as que iniciaram a vida sexual antes dos 16 anos e reportaram quatro ou mais parceiros sexuais nos cinco anos anteriores à entrevista foram menos testadas. Não se observou aumento significativo da testagem entre homens, exceto para os de 55-65 anos, renda per capita entre 1-3 e 5-10 salários mínimos, aposentados, protestantes históricos e adeptos de cultos afro-brasileiros, moradores da região Norte/Nordeste e os que declararam parceria homo/bissexual ou não tiveram relações sexuais nos cinco anos anteriores à entrevista. Não aumentou a freqüência de testagem entre pessoas auto-avaliadas como sob alto risco para o HIV. Entre as mulheres, a freqüência de testagem pré-natal aumentou e a testagem por trabalho diminuiu entre os homens. Em 2005, metade dos testados não recebeu orientação antes ou após o teste. CONCLUSÕES: Houve expansão desigual na testagem, atingindo principalmente mulheres em idade reprodutiva, adultas e pessoas com melhores condições sociais. A testagem parece estar aumentando no País sem a devida atenção à decisão autônoma das pessoas e sem o provimento de maior e melhor oferta de aconselhamento

Gênero, saúde materna e o paradoxo perinatal

Nos últimos 20 anos, houve uma melhoria de praticamente todos os indicadores da saúde materna no Brasil, assim como grande ampliação do acesso aos serviços de saúde. Paradoxalmente, não há qualquer evidência de melhoria na mortalidade materna. Este texto tem como objetivo trazer elementos para a compreensão deste paradoxo, através do exame dos modelos típicos de assistência ao parto, no SUS e no setor privado. Analisaremos as propostas de mudança para uma assistência mais baseada em evidências sobre a segurança destes modelos, sua relação com os direitos das mulheres, e com os conflitos de interesse e resistências à mudança dos modelos. Examinamos os pressupostos de gênero que modulam a assistência e os vieses de gênero na pesquisa neste campo, expressos na superestimação dos benefícios da tecnologia, e na subestimação ou na negação dos desconfortos e efeitos adversos das intervenções. Crenças da cultura sexual não raro são tidas como explicações 'científicas' sobre o corpo, a parturição e a sexualidade, e se refletem na imposição de sofrimentos e riscos desnecessários, nas intervenções danosas à integridade genital, e na negação do direito a acompanhantes. Esta 'pessimização do parto' é instrumental para favorecer, por comparação, o modelo da cesárea de rotina. Por fim, discutimos como o uso da categoria gênero pode contribuir para promover direitos e mudanças institucionais, como no caso dos acompanhantes no parto

A construção do direito à saúde no Brasil

O direito à saúde recebeu - pela primeira vez - tratamento constitucional no brasil em 1988, fruto de grande participação popular. Neste estudo, se busca compreender a extensão dessa afirmação e verificar sua implementação normativa e jurisprudencial. A partir do estudo da evolução dos conceitos de saúde e de direito, concluiu-se que o direito à saúde deve implicar a constante participação popular para que possa ser delimitado. Verificou-se, também, que o arcabouço normativo vem sendo construído em conformidade com as exigências constitucionais. Quanto à construção jurisprudencial, se percebeu que ela vem acontecendo de forma errática e que os tribunais superiores raramente enfrentam a discussão da política de saúde desenhada na Constituição da República Federativa do Brasil de 1988. Concluiu-se que a afirmação constitucional tem demonstrado vigor, haja vista o grande desenvolvimento normativo conforme `compreensão contemporânea; e que o controle judicial da realização da política sanitária é ainda incipiente

Vigilância em saúde no Brasil: os desafios dos riscos sanitários do século XXI e a necessidade de criação de um sistema nacional de vigilância em saúde

The technological development experienced in the contemporary world are transforming society and relations between State and people. The mobility of human being has reached levels never before imagined and a person can move from one side of the world to the other side in less than 24 hours. This mobility also includes goods and services, giving the keynote of the globalized world of the XXI Century. In this context, the risks of diseases and others health problems are intensely amplified. Nowadays, an epidemic that begins in China can arrive in Brazil the following day. Brazil recognizes health as a universal right and also consider it a State's obligation. Therefore, the State of Brazil is obligated to organize itself to eliminate or control health risks. Today, the organization of the Brazilian State regarding the surveillance of risks of diseases and other health problems is fragmented and includes sanitary surveillance (focused on goods, products and services), epidemiological surveillance (diseases and investigations of other risks) and environmental surveillance in health (the environment in general, including the workplace). This fragmentation causes problems for the management and consolidation of strategic information for health protection. Brazil has the need to think about an other model of organization that put together all "kinds" of surveillances within a single coordinated system, called the National System of Health Surveillance, which would be able to coordinate the various specialties of health surveillance that exists in the country in order to provide a effective system of information and health surveillance, able to face emergency situations of public health

Transforming Youth Identities: Interactions Across ""Races/Colors/Ethnicities,"" Gender, Class, and Sexualities in Johannesburg, South Africa

In South Africa, and especially in Johannesburg, apartheid's ""racial"" paradigms are being transformed. Fifteen years after the end of apartheid and the elimination of all forms of inequity based on notion of ""race,"" including the abolition of the Immorality Act of 1949 that prohibited mixed marriages, the discourses of youth challenge preestablished boundaries. Today, the South African Constitution gives people the right to proclaim their sexual orientation and to shape their own identities. Through ethnographic observations carried out in Johannesburg and in-depth interviews with young people, this paper explores transforming notions of identity based on ""race/color/ethnicity,"" gender, class, and sexuality. The dynamics and challenges faced by young people with regards to mixed interactions in post-apartheid Johannesburg are analyzed and the paper looks at how "" race,"" gender, and sexuality interact in the various spaces in Johannesburg and how they affect young people's lives, particularly their perceptions of risk, violence, and HIV/AIDS vulnerability.

An insight into the sialotranscriptome of the brown dog tick, Rhipicephalus sanguineus

Background: Rhipicephalus sanguineus, known as the brown dog tick, is a common ectoparasite of domestic dogs and can be found worldwide. R. sanguineus is recognized as the primary vector of the etiological agent of canine monocytic ehrlichiosis and canine babesiosis. Here we present the first description of a R. sanguineus salivary gland transcriptome by the production and analysis of 2,034 expressed sequence tags (EST) from two cDNA libraries, one consctructed using mRNA from dissected salivary glands from female ticks fed for 3-5 days (early to mid library, RsSGL1) and the another from ticks fed for 5 days (mid library, RsSGL2), identifying 1,024 clusters of related sequences. Results: Based on sequence similarities to nine different databases, we identified transcripts of genes that were further categorized according to function. The category of putative housekeeping genes contained similar to 56% of the sequences and had on average 2.49 ESTs per cluster, the secreted protein category contained 26.6% of the ESTs and had 2.47 EST's/clusters, while 15.3% of the ESTs, mostly singletons, were not classifiable, and were annotated as ""unknown function"". The secreted category included genes that coded for lipocalins, proteases inhibitors, disintegrins, metalloproteases, immunomodulatory and antiinflammatory proteins, as Evasins and Da-p36, as well as basic-tail and 18.3 kDa proteins, cement proteins, mucins, defensins and antimicrobial peptides. Comparison of the abundance of ESTs from similar contigs of the two salivary gland cDNA libraries allowed the identification of differentially expressed genes, such as genes coding for Evasins and a thrombin inhibitor, which were over expressed in the RsSGL1 (early to mid library) versus RsSGL2 (mid library), indicating their role in inhibition of inflammation at the tick feeding site from the very beginning of the blood meal. Conversely, sequences related to cement (64P), which function has been correlated with tick attachment, was largely expressed in the mid library. Conclusions: Our survey provided an insight into the R. sanguineus sialotranscriptome, which can assist the discovery of new targets for anti-tick vaccines, as well as help to identify pharmacologically active proteins.

Democracy on the Edge: Limits and Possibilities in the Implementation of an Urban Reform Agenda in Brazil

The 1990s in Brazil were a time of institutional advances in the areas of housing and urban rights following the signing of the new constitution in 1988 that incorporated the principles of the social function of cities and property, recognition of the right to ownership of informal urban squatters and the direct participation of citizens in urban policy decision processes. These propositions are the pillars of the urban reform agenda which, since the creation of the Ministry of Cities by the Lula government, has come under the federal executive branch. This article evaluates the limitations and opportunities involved in implementing this agenda on the basis of two policies proposed by the ministry - the National Cities Council and the campaign for Participatory Master Plans - focusing the analysis on government organization in the area of urban development in its relationship with the political system and the characteristics of Brazilian democracy. Resume Au Bresil, les annees 1990 ont ete marquees par des progres institutionnels en matiere de logement et de droits urbains, dans le sillage de la Constitution de 1988 qui integre les principes d`une fonction sociale de la ville et de la propriete urbaine, ainsi que la reconnaissance du droit a la propriete pour les squatters urbains et la participation directe des citoyens aux processus d`elaboration des politiques urbaines. Ce sont egalement les piliers du programme de reforme urbaine qui releve de l`executif federal depuis la creation d`un ministere des Villes par le gouvernement Lula. Pour evaluer les limites et potentiels lies a la mise en place de ce programme, cet article s`appuie sur deux politiques publiques proposees par le ministere, le Conseil national des villes et la campagne en faveur des Plans directeurs participatifs, en analysant plus particulierement l`organisation gouvernementale en matiere d`urbanisme par rapport au systeme politique et aux caracteristiques de la democratie bresilienne.

Towards a History didactics definition

This paper aims to define history didactics along the lines of the current German literature, which conceives it to be closer to history than to education. Associated to the word Geschichtsdidaktik, this definition is opposed to the concepts of history didactics as the art of teaching - Lehrkunst - history or as a collection of methods used both in the teaching of history and in the teaching of other school subjects - Unterrichtsmethoden. In opposition to these two definitions, this paper discusses German, French and Brazilian literatures to propose a conception of history didactics as a subarea of history, once it does not encompass only history teaching, but all history elaborations without a scientific form - nicht- wissenschaftsformigen Geschichtsverarbeitungen.

Periurethral Suspension Stitch During Robot-Assisted Laparoscopic Radical Prostatectomy: Description of the Technique and Continence Outcomes

Background: Several studies have shown that robot-assisted laparoscopic radical prostatectomy (RALP) is feasible, with favorable complication rates and short hospital times. However, the early recovery of urinary continence remains a challenge to be overcome. Objective: We describe our technique of periurethral retropubic suspension stitch during RALP and report its impact on early recovery of urinary continence. Design, setting, and participants: We analyze prospectively 331 consecutive patients who underwent RALP, 94 without the placement of suspension stitch (group 1) and 237 with the application of the suspension stitch (group 2). Surgical procedure: The only difference between the groups was the placement of the puboperiurethral stitch after the ligation of the dorsal venous complex (DVC). The periurethral retropubic stitch was placed using a 12-in monofilament polyglytone suture on a CTI needle. The stitch was passed from right to left between the urethra and DVC, and then through the periostium on the pubic bone. The stitch was passed again through the DVC, and then through the pubic bone in a figure eight, and then tied. Measurements: Continence rates were assessed with a self-administered validated questionnaire (Expanded Prostate Cancer Index Composite [EPIC] at 1, 3, 6, and 12 mo after the procedure. Continence was defined as the use of no absorbent pads or no leakage of urine. Results and limitations: In group 1, the continence rate at 1, 3, 6, and 12 mo postoperatively was 33%, 83%, 94.7%, and 95.7%, respectively; in group 2, the continence rate was 40%, 92.8%, 97.9%, and 97.9%, respectively. The suspension technique resulted in significantly greater continence rates at 3 mo after RALP (p = 0.013). The median/mean interval to recovery of continence was also statistically significantly shorter in the suspension group (median: 6 wk; mean: 7.338 wk: 95% confidence interval [CI]: 6.387-8.288) compared to the non-suspension group (median: 7 wk; mean: 9.585 wk: 95% CI: 7.558-11.612; log rank test, p = 0.02). Conclusions: The suspension stitch during RALP resulted in a statistically significantly shorter interval to recovery of continence and higher continence rates at 3 mo after the procedure.

Influence of visual feedback on pelvic floor muscle strength

Objective: The objective of this study is to evaluate the visual feedback influence on pelvic floor muscle contraction. Study design: Seventeen nulliparous, urinary-continent women participated in this study. Pelvic floor muscle strength with and without the use of visual feedback was measured with a dynamometric speculum in two directions (anteroposterior and left-right). To compare the mean strength values with and without the use of visual feedback, the t test was applied. Results: There was no significant difference between the pelvic floor muscle anteroposterior strength values with and without the use of visual feedback (p = 0.30), and no significant difference for the left-right strength (p = 0.37). Conclusion: There was no difference between the pelvic floor muscle strength values with and without the use of visual feedback. (C) 2010 Elsevier Ireland Ltd. All rights reserved.

Communication between organ donor families and recipients: A definitely controversial subject

In transplant centers, few topics are more controversial than communication between organ donor families (ODF) and recipients (RE). The Organ Procurement Organizations and transplant centers have felt obliged to protect the confidentiality and interests of ODF and RE. However, some authors have reported favorable effects of contact between ODF and RE. This study sought to investigate the current situation of the communication between ODF and RE from the viewpoint of transplanted patients (n = 50) and waiting transplant patients (n 50) at a Brazilian University Hospital, ODF (n = 10), physicians from transplant centers (n 50), as well as the opinion of the general population of a Brazilian city (n = 100). This work was developed as a survey whose questions related to the issue of communication between ODF and RE. The results showed that the majority of transplanted patients (82%) and patients awaiting transplant (60%) wanted to meet ODF to express their gratitude for receiving the organ. Likewise, ODF (67%) wanted to have a meeting with recipients, which allowed them to confirm the benefit of their donation. The general population was also favorable (66%) to ODF and RE communication. In contrast, the physicians (74%) were opposed to the ODF and RE contact. They affirmed that direct contact could lead to serious emotional conflicts or attempts of material involvement. One believes that decisions concerning the contact between ODF and RE would have to be determined by the involved parties. The transplant team could analyze the requests case by case, but ODF and RE must have the right to make the final decision.

THE EFFECT OF DIFFERENT VOLUMES OF ACUTE RESISTANCE EXERCISE ON ELDERLY INDIVIDUALS WITH TREATED HYPERTENSION

Scher, LML, Ferriolli, E, Moriguti, JC, Scher, R, and Lima, NKC. The effect of different volumes of acute resistance exercise on elderly individuals with treated hypertension. J Strength Cond Res 25(4): 1016-1023, 2011-Acute resistance exercise can reduce the blood pressure (BP) of hypertensive subjects. The aim of this study was to evaluate the effect of different volumes of acute low-intensity resistance exercise over the magnitude and the extent of BP changes in treated hypertensive elderly individuals. Sixteen participants (7 men, 9 women), with mean age of 68 6 5 years, performed 3 independent randomized sessions: Control (C: 40 minutes of rest), Exercise 1 (E1: 20 minutes, 1 lap in the circuit), and Exercise 2 (E2: 40 minutes, 2 laps in the circuit) with the intensity of 40% of 1 repetition maximum. Blood pressure was measured before (during 20 minutes) and after each session (every 5 minutes during 60 minutes) using both a mercury sphygmomanometer and a semiautomatic device (Omrom-HEM-431). After that, 24-hour ambulatory blood pressure monitoring was performed (Dyna-MAPA). Blood pressure decreased during the first 60 minutes (systolic: p < 0.01, diastolic: p < 0.05) after all exercise sessions. Only the highest volume session promoted a reduction of mean systolic 24-hour BP and awake BP (p, 0.05) after exercise, with higher diastolic BP during sleep (p, 0.05). Diastolic 24-hour BP and both systolic and diastolic BP during sleep were higher after E1 (p, 0.05). Concluding, acute resistive exercise sessions in a circuit with different volumes reduced BP during the first 60 minutes after exercise in elderly individuals with treated hypertension. However, only the highest volume promoted a reduction of mean 24-hour and awake systolic BP.
