Health survey on the Ilha da Conceição, state of Rio de Janeiro, II: selected health characteristics in children

As part of the health survey on the Ilha da Conceição, a 25 percent random sample of households was identified and a health guestionnaire completed at 236 households. These households contained 536 children, of whom 239 were under age six. Prenatal care had been obtained by 70 percent of the mothers during the pregnancies of the youngest children and 83 percent of these children had been born in hospital. The use of available health facilities was reported more frequently for the younger children in comparison to the older children. Over 90 percent of the children had been vaccinated against one or more diseases but only 50 to 60 percent of the children had complete vaccination against pertussis, diphtheria and tetanus. Almost two-thirds of the stool specimens from the children revealed evidence of parasites and were most commonly found in children two to three years of age. Low hemoglobin values were found commonly under age three and hemoglobin leveis ábove 12 grams were not commonly found until age six. Compared with a North American standard for height and weight, proportionately more children on the Ilha da Conceição were found below the 25th and 3rd percentiles. These findings suggest that an improved health status for the children on the Ilha da Conceição would result from a household health record maintained at the island clinic including current information on vaccination status of all children, and a health education program focused on expectant mothers and the well baby clinic program.

Tuberculose nos imigrantes : análise comparativa entre os biénios 2000-2001 e 2008-2009 das características sóciodemográficas e clínicas dos casos de tuberculose em Portugal Continental

RESUMO - Objectivos: Este estudo pretende caracterizar os casos de Tuberculose notificados em Portugal Continental, em função das suas características sociodemográficas e clínicas, aferir a sua evolução através da comparação dos biénios 2000/2001 e 2008/2009 e a possibilidade de existência de diferenças entre os casos de Tuberculose na população imigrante e não imigrante. Métodos: Foi desenvolvido um estudo descritivo de casos notificados nos biénios 2000/2001 (n= 9182) e 2008/2009 (n= 6087). A fonte de dados foi o Sistema De Vigilância Intrínseco ao Programa Nacional de Luta contra a Tuberculose (SVIG-TB). Para calcular as incidências foram utilizados os dados disponibilizados pelo Instituto Nacional de Estatística e pelo Serviço de Estrangeiros e Fronteiras referentes à população não imigrante e imigrante residente em Portugal. Foi utilizado o teste do Qui-quadrado e o teste exacto de Fisher para analisar possíveis relações entre variáveis qualitativas. O teste de Mann-Whitney foi utilizado para comparação da distribuição entre variáveis quantitativas nos dois grupos. A odds ratio foi determinada para aferir a força de associação entre as variáveis e a condição de imigrante. Resultados: No biénio 2000/2001, 10,2% dos casos notificados eram de imigrantes e no biénio 2008/2009 aumentou para 13,3%. Relativamente às características sociodemográficas dos pacientes, observaram-se diferenças estatisticamente significativas apenas na idade. Nas características clínicas observaram-se diferenças significativas em algumas patologias associadas, nomeadamente na infecção VIH (p <0,001: OR=1,696).Quanto aos factores de risco, observaram-se diferenças no consumo do tabaco (p <0,001: OR= 0,499) e drogas (p <0,001; OR= 0,582). Relativamente à situação final de tratamento existem diferenças significativas nas categorias em tratamento (p <0,001;OR=0,661), tratamento completo (p <0,001;OR =1,293) e morte (p <0,001; OR=1,806). Conclusões: O número de casos de Tuberculose em Portugal, bem como a taxa de incidência, diminuíram do biénio 2000/2001 para o biénio 2008/2009 em ambos os grupos. Os imigrantes são mais jovens, têm maior risco de infecção VIH e menor risco de patologias crónicas.

Human immune responses during schistosomiasis mansoni

Studies of immune responses as they occur in patients with schistosomiasis appear to progress relative to corrent technological advances, and to advance despite the understandable inability to pursue in vivo manipulations in this host/parasite system. Emphasis is most often placed on making immunological comparisons between such patient groups as reinfected/non-reinfected, intestinals/hepatosplenic, high/low intensities of infection, infected/uninfected within endemic areas, and those born of infected/uninfected mothers. Based on these types of comparisons, reasonable conjectures can be made regarding the immunological occurrences during this chronic exposure condition. Some consideration is now being given to the immune mechanisms of some of the observations made, and while some of these must then be carried back to experimental models for further manipulation-based analysis, new technological developments continue to assist in the field/bench ability to ask questions that might assist our understanding to a point where this knowledge can be applied to shaping developmental approaches to vaccine development and the goal of alleviating morbidity.

Biochemical behavior of Trypanosoma cruzi strains isolated from mice submitted to specific chemotherapy

To investigate the influence of chemotherapy on the biochemical beha vior of Trypanosoma cruzi strains, three groups of mice were infected with one of three strains of T. cruzi of different biological and isoenzymic patterns (Peruvian, 21 SF and Colombian strains). Each group was subdivided into subgroups: 1 - treated with nifurtimox; 2 - treated with benznidazole and 3 - untreated infected controls. At the end of treatment, that lasted for 90 days, xenodiagnosis, sub inoculation of blood into new born mice and haemoculture were performed as tests of cure. From the positive tests, 22 samples of T. cruzi were isolated from all subgroups. Electrophoretic analysis of the isoenzymes PGM, GP1, ALAT and AS AT failed to show any difference between parasite strains isolated from treated and untreated mice, which indicates that no detectable clonal selection or parasite genetic markers alterations concerning the isoenzymes analysed have been determined by treatment with drugs of recognized antiparasitic effect, suggesting stability of the phenotypic characteristics of the three biological types of T. cruzi strains.

Mother-child transmission of Chagas disease: could coinfection with human immunodeficiency virus increase the risk?

A study was conducted on all newborns from mothers with Chagas disease who were attended at Hospital Donación F. Santojanni between January 1, 2001, and August 31, 2007. Each child was investigated for the presence of Trypanosoma cruzi parasitemia through direct examination of blood under the microscope using the buffy coat method on three occasions during the first six months of life. Serological tests were then performed. Ninety-four children born to mothers infected with Trypanosoma cruzi were attended over the study period. Three of these children were born to mothers coinfected with the human immunodeficiency virus. Vertical transmission of Chagas disease was diagnosed in 13 children, in all cases by identifying parasitemia. The overall Chagas disease transmission rate was 13.8% (13/94). It was 100% (3/3) among the children born to mothers with HIV infection and 10.9% (10/91) among children born to mothers without HIV [Difference = 0.89; CI95 = 0.82-0.95; p = 0.0021]. We concluded that coinfection with HIV could increase the risk of vertical transmission of Chagas disease.

Determinants of mother-baby relationship evaluated during pregnancy

ABSTRACT Background Mental health promotion is supported by a strong body of knowledge and is a matter of public health with the potential of a large impact on society. Mental health promotion programs should be implemented as soon as possible in life, preferably starting during pregnancy. Programs should focus on malleable determinants, introducing strategies to reduce risk factors or their impact on mother and child, and also on strengthening protective factors to increase resilience. The ambition of early detecting risk situations requires the development and use of tools to assess risk, and the creation of a responsive network of services based in primary health care, especially maternal consultation during pregnancy and the first months of the born child. The number of risk factors and the way they interact and are buffered by protective factors are relevant for the final impact. Maternal-fetal attachment (MFA) is not yet a totally understood and well operationalized concept. Methodological problems limit the comparison of data as many studies used small size samples, had an exploratory character or used different selection criteria and different measures. There is still a lack of studies in high risk populations evaluating the consequences of a weak MFA. Instead, the available studies are not very conclusive, but suggest that social support, anxiety and depression, self-esteem and self-control and sense of coherence are correlated with MFA. MFA is also correlated with health practices during pregnancy, that influence pregnancy and baby outcomes. MFA seems a relevant concept for the future mother baby interaction, but more studies are needed to clarify the concept and its operationalization. Attachment is a strong scientific concept with multiple implications for future child development, personality and relationship with others. Secure attachment is considered an essential basis of good mental health, and promoting mother-baby interaction offers an excellent opportunity to intervention programmes targeted at enhancing mental health and well-being. Understanding the process of attachment and intervening to improve attachment requires a comprehension of more proximal factors, but also a broader approach that assesses the impact of more distal social conditions on attachment and how this social impact is mediated by family functioning and mother-baby interaction. Finally, it is essential to understand how this knowledge could be translated in effective mental health promoting interventions and measures that could reach large populations of pregnant mothers and families. Strengthening emotional availability (EA) seems to be a relevant approach to improve the mother-baby relationship. In this review we have offered evidence suggesting a range of determinants of mother-infant relationship, including age, marital relationship, social disadvantages, migration, parental psychiatric disorders and the situations of abuse or neglect. Based on this theoretical background we constructed a theoretical model that included proximal and distal factors, risk and protective factors, including variables related to the mother, the father, their social support and mother baby interaction from early pregnancy until six months after birth. We selected the Antenatal Psychosocial Health Assessment (ALPHA) for use as an instrument to detect psychosocial risk during pregnancy. Method Ninety two pregnant women were recruited from the Maternal Health Consultation in Primary Health Care (PHC) at Amadora. They had three moments of assessment: at T1 (until 12 weeks of pregnancy) they filed out a questionnaire that included socio-demographic data, ALPHA, Edinburgh post-natal Depression Scale (EDPS), General Health Questionnaire (GHQ) and Sense of Coherence (SOC); at T2 (after the 20th weeks of pregnancy) they answered EDPS, SOC and MFA Scale (MFAS), and finally at T3 (6 months after birth), they repeated EDPS and SOC, and their interaction with their babies was videotaped and later evaluated using EA Scales. A statistical analysis has been done using descriptive statistics, correlation analysis, univariate logistic regression and multiple linear regression. Results The study has increased our knowledge on this particular population living in a multicultural, suburb community. It allow us to identify specific groups with a higher level of psychosocial risk, such as single or divorced women, young couples, mothers with a low level of education and those who are depressed or have a low SOC. The hypothesis that psychosocial risk is directly correlated with MFAS and that MFA is directly correlated with EA was not confirmed, neither the correlation between prenatal psychosocial risk and mother-baby EA. The study identified depression as a relevant risk factor in pregnancy and its higher prevalence in single or divorced women, immigrants and in those who have a higher global psychosocial risk. Depressed women have a poor MFA, and a lower structuring capacity and a higher hostility to their babies. In average, depression seems to reduce among pregnant women in the second part of their pregnancy. The children of immigrant mothers show a lower level of responsiveness to their mothers what could be transmitted through depression, as immigrant mothers have a higher risk of depression in the beginning of pregnancy and six months after birth. Young mothers have a low MFA and are more intrusive. Women who have a higher level of education are more sensitive and their babies showed to be more responsive. Women who are or have been submitted to abuse were found to have a higher level of MFA but their babies are less responsive to them. The study highlights the relevance of SOC as a potential protective factor while it is strongly and negatively related with a wide range of risk factors and mental health outcomes especially depression before, during and after pregnancy. Conclusions ALPHA proved to be a valid, feasible and reliable instrument to Primary Health Care (PHC) that can be used as a total sum score. We could not prove the association between psychosocial risk factors and MFA, neither between MFA and EA, or between psychosocial risk and EA. Depression and SOC seems to have a clear and opposite relevance on this process. Pregnancy can be considered as a maturational process and an opportunity to change, where adaptation processes occur, buffering risk, decreasing depression and increasing SOC. Further research is necessary to better understand interactions between variables and also to clarify a better operationalization of MFA. We recommend the use of ALPHA, SOC and EDPS in early pregnancy as a way of identifying more vulnerable women that will require additional interventions and support in order to decrease risk. At political level we recommend the reinforcement of Immigrant integration and the increment of education in women. We recommend more focus in health care and public health in mental health condition and psychosocial risk of specific groups at high risk. In PHC special attention should be paid to pregnant women who are single or divorced, very young, low educated and to immigrant mothers. This study provides the basis for an intervention programme for this population, that aims to reduce broad spectrum risk factors and to promote Mental Health in women who become pregnant. Health and mental health policies should facilitate the implementation of the suggested measures.

Etiological treatment of young women infected with Trypanosoma cruzi, and prevention of congenital transmission

The objective was to detect Trypanosoma cruzi infection in 32 children in Salta, Argentina, born to 16 chronically infected young women who were treated with benznidazole. Tests were performed to assess the efficacy of treatment after 14 years. At the end of the follow up, 87.5% of the women were non-reactive to EIA tests, 62.5% to IHA and 43.8% to IFA. 62.5% of the women were non-reactive according to two or three serological tests. No infected children were detected among the newborns of mothers treated before their pregnancy.

Teleoperation of a service robot using a mobile device

Teleoperation is a concept born with the rapid evolution of technology, with an intuitive meaning "operate at a distance." The first teleoperation system was created in the mid 1950s, which were handled chemicals. Remote controlled systems are present nowadays in various types of applications. This dissertation presents the development of a mobile application to perform the teleoperation of a mobile service robot. The application integrates a distributed surveillance (the result of a research project QREN) and led to the development of a communication interface between the robot (the result of another QREN project) and the vigilance system. It was necessary to specify a communication protocol between the two systems, which was implemented over a communication framework 0MQ (Zero Message Queue). For the testing, three prototype applications were developed before to perform the test on the robot.

Estratégia de vacinação para eliminar o sarampo : um estudo sero-epidemiológico em diferentes populações vacinais

RESUMO - Introdução: As alterações epidemiológicas do sarampo em Portugal, assim como a existência de surtos de doença na Europa e noutras regiões do mundo, associadas ao facto de a informação sero epidemiológica atualizada ser escassa e pontual, e nem sempre estar relacionada com o estado vacinal, dificultam a tomada de decisões fundamentadas na área da vacinação, nomeadamente no que respeita às idades ótimas para a administração de VASPR I e VASPR II. Este estudo pretende avaliar a adequação da estratégia vacinal contra o sarampo vigente em Portugal, no que diz respeito às idades para realização da VASPR I e da VASPR II, no sentido de dar continuidade ao cumprimento do objetivo de eliminar a doença em território nacional. Material e métodos: Foi realizado um estudo com 206 recém-nascidos filhos de mães com diferentes estados vacinais contra o sarampo (0 doses, 1 dose e 2 doses). Também foram estudados 186 adolescentes/jovens que realizaram a VASPR II em diferentes idades. Os dados obtidos provêm de 3 fontes de informação: história vacinal documentada; questionários aplicados por entrevista e informação serológica. A informação serológica foi obtida através do doseamento do título de anticorpos específicos antissarampo (ATS IgG) em soros, recorrendo ao método imunoenzimático ELISA do kit Enzygnost® Anti-measles Virus/IgG, do fabricante Siemens. Resultados: A taxa de cobertura vacinal da vacina contra o sarampo aumentou de valores de pouco mais de 30% na geração nascida antes de 1977, com uma única dose de vacina, para valores superiores a 95 % na geração nascida depois de 1993, com duas doses de vacina. A concentração geométrica de ATS IgG no sangue do cordão umbilical aumentou com o aumento da idade da mãe (r2 = 0,092; p = 0,001). Os recém-nascidos filhos de mães vacinadas, apresentam menor quantidade de ATS IgG do que os filhos de mães não vacinadas (p < 0,0001), independentemente do número de doses que as suas mães tenham recebido (p = 0,222). A concentração geométrica média (CGM) de ATS IgG nos jovens e adolescentes diminui com o tempo decorrido desde a toma de VASPR II (r2 = 0,244; p = 0,001). Não foram encontradas diferenças estatisticamente significativas entre a média de ATS IgG dos indivíduos que se vacinaram com VASPR II aos 5-6 anos de idade e os que se vacinaram entre os 10-13 anos de idade (p = 0,301). Após 9 anos de VASPR II mais de 5 % dos indivíduos já não estão seropositivos contra o sarampo.Discussão: A CGM de ATS IgG aumentou com a idade da mãe, provavelmente porque as mães pertencentes às gerações mais novas contactaram menos com o vírus selvagem do sarampo, devido aos efeitos das elevadas taxas de cobertura vacinal. Os recém-nascidos filhos das mães mais novas, apesar de apresentarem menor CGM de ATS IgG, ao final de 12 meses de idade poderão ainda apresentar um teor de ATS IgG que pode interferir com a resposta vacinal à VASPR I. Vacinar com VASPR II aos 5-6 anos de idade ou vacinar entre os 10-13 anos parece ser indiferente o que parece relevante é o tempo que passa desde a última vacinação VASPR II. Nove anos depois de VASPR II a percentagem de seronegativos já ultrapassa os 5% recomendados pela OMS. Conclusão: As idades da toma de VASPR I e VASPR II poderão ter de ser alteradas por forma a adequarem-se às mudanças epidemiológicas ocorridas nos últimos anos em Portugal e contribuírem para a eliminação do sarampo no país.

Liberdade e tolerância religiosa: "portugueses não católicos" no ultramar do século XIX

The personal legal status of native non catholic people of Portuguese colonial Empire during the nineteenth century, their position in what concerns Portuguese citizenship, is the main subject of this article. While discussing constitutional articles on religion, Portuguese deputies of the nineteenth century were confronted with a set of problems about that status which they find difficult to solve: should non catholic peoples who were born in Portuguese colonial territory be treated as plain Portuguese citizens or where they just “savage people”, “colonial subjects” or, in a more optimistic approach, “civilizing subjects”. The results were not conclusive, giving rise to an “uncertainty principle” which enabled central and local government to decide in an almost casuistic way about native people status and rights.
