Infecção congênita pelo citomegalovírus: estudo realizado na Fundação Santa Casa de Misericórdia do Pará

O citomegalovírus é um vírus de DNA, pertencente à família Herpesviridae, subfamília Beta-herpesvirinae. Sua distribuição é universal e pode causar infecções congênitas e perinatais, assim como durante a infância e na idade adulta. É um dos principais patógenos responsáveis pela morbidade e mortalidade em pacientes imunocomprometidos. Foi estudada a incidência da infecção congênita pelo citomegalovírus, na maternidade da Fundação Santa Casa Misericórdia do Pará, no período de novembro de 1994 a maio de 1995. A amostra trabalhada constou de 663 recém-nascidos e suas respectivas mães. O peso dos recém-nascidos variou de 900 a 5450 g, com uma média de 3046g. Em 11,4% das crianças foi observado baixo peso ao nascer. A avaliação pelo isolamento do vírus da saliva dos 663 recém-nascidos, através da inoculação em células primárias de fibroblasto de prepúcio humano, mostrou 3,2% (21) de positividade. A pesquisa de anticorpos IgM específicos para o CMV, através do método ELISA, utilizando-se sangue do cordão umbilical do mesmo grupo de recém-nascidos foi positiva em 2,1% (14). Para o diagnóstico da infecção congênita pelo CMV, a análise estatística pelo Teste de McNemar dos Pares Discordantes (p)=0,0233 e Teste do Qui-Quadrado da Homogeneidade (p)<0,01 demonstrou que o isolamento do citomegalovírus da saliva foi mais sensível que a detecção de anticorpos IgM no sangue do cordão umbilical. Dos 21 recém-nascidos infectados, 28,5% (6) apresentaram nas primeiras 24 horas de vida, sintomatologia sugestiva de infecção congênita. Os sinais e sintomas encontrados foram microcefalia (4), prematuridade (3), hepatoesplenomegalia (2), pequeno para a idade gestacional (2) e icterícia precoce (1). A pesquisa de anticorpos IgG específicos para o CMV, pelo método ELISA, foi positiva em 90,2% das puérperas. Das 21 mulheres que transmitiram o vírus para o concepto, foram detectados anticorpos IgM em 4. A entrevista pessoal com as mães dos recém-nascidos revelou nível socioeconômico baixo e assistência pré-natal deficiente, com 26,4% das puérperas sem nenhuma consulta durante o período gestacional. Em nossa amostra, a idade materna variou de 12 a 42 anos, com idade média de 22,2 anos, sendo que a idade das mães dos recém-nascidos infectados foi inferior a 25 anos.

Preditores da desnutrição infantil em populações ribeirinhas do Pará

Objetivo: Identificar os determinantes da desnutrição infantil em crianças menores de dois anos de idade em populações ribeirinhas do Pará. Métodos: Estudo transversal foi desenvolvido com 203 crianças residentes em quatro comunidades ribeirinhas: Aveiro (região Sudoeste), Barcarena (região Metropolitana), Cametá (região Nordeste) e Santarém (região do Baixo Amazonas) por meio de entrevista junto ao responsável pela criança. A variável dependente foi desnutrição, considerada presente para índice estatura para idade < -1 escores z de acordo com a referência atual da Organização Mundial da Saúde. As variáveis independentes foram características: de moradia, do chefe da família, da mãe da criança, do pré-natal, do padrão alimentar da família, do nascimento da criança, dos cuidados maternos e demográficos da criança. A prevalência da desnutrição foi calculada conforme indicadores básicos, subjacentes e imediatas, considerando-se a distância entre as variáveis que compõem os indicadores e o desfecho. Análise multinível foi realizada por regressão logística tendo em conta a hierarquia das relações entre os indicadores e a desnutrição, considerando-se p<0,005. Resultados: A prevalência de desnutrição atingiu 35,0 % das crianças estudadas, variando de 28,6% em Aveiro a 43,1% em Barcarena. As variáveis que se associaram com desnutrição foram baixo peso ao nascer e maior idade da criança. A idade da criança foi o preditor da desnutrição: a chance de uma criança entre 12 e 17 meses de idade apresentar desnutrição foi 3,4 vezes maior do que a de uma criança com menos de seis meses, aumentando em cinco vezes para as crianças entre 18 e 23 meses. Conclusão: Em populações ribeirinhas, a desnutrição em menores de dois anos mostra-se ainda como um grave problema de saúde pública, possivelmente pelo maior tempo de exposição aos fatores de risco ambientais.

Sobrepeso pré-gestacional associa-se a ganho ponderal excessivo na gestação

PURPOSE: To evaluate the adequacy of gestational weight gain and to determine its association with maternal socioeconomic, demographic and nutritional factors and health care, to estimate the prevalence of low birth weight, macrosomia, preterm birth and cesarean delivery and to identify the association of these outcomes with the adequacy of weight gain. METHODS: A cross-sectional study was performed in 2009/2010 to obtain socioeconomic, demographic, nutritional, dietary and physical activity data of pregnant women assisted by primary health care in a municipality of the state of São Paulo. Subsequently, data were collected from the medical records to evaluate gestational weight gain. Type of delivery, birth weight and gestational age at delivery were obtained from the Livebirths Information System. Gestational weight gain was evaluated according to the recommendations of the Institute of Medicine (2009). Associations were investigated by comparing the frequencies and by logistic regression, with excessive weight gain (yes, no) and insufficient gain (yes, no) being the dependent variables. RESULTS: A total of 212 pregnant women were studied: 50.5% had excessive gain and 19.8% insufficient weight gain. Only prepregnancy nutritional status was associated with adequacy of weight gain: compared with normal weight, prepregnancy overweight women had a four-fold higher chance to gain excessive weight (OR 4.66, 95%CI 2.19-9.4). Nearly a third of babies were born by caesarian section, 5.7% were premature, 7.1% were underweight and 4.7% were macrosomic. There was no association between adequacy of gestational weight gain and these outcomes. CONCLUSION: The proportion of inadequate gestational weight gain was high. Overweight pregnant women have a four-fold higher chance to gain excessive weight, and priority should be given to actions promoting adequate prenatal weight gain.

Análise histomorfométrica do músculo cardíaco de ratos recém natos gerados por matrizes submetidas ao tabagismo passivo associado ao exercício

Maternal smoking during pregnancy causes heart changes, impaired fetal growth, spontaneous abortion and low birth weight. Even in pregnant women exposed to cigarette smoke these changes can be observed. But the exercise is to answer the increased fetal weight, besides the improvement of cardiorespiratory fitness of the pregnant and the fetus. The objective of this study was to analyze the ventricular muscle of young rats subjected to passive smoking associated with aquatic exercise. For the experiments used 24 female rats were divided into: GC (control), GE (exercise protocol in the water), GF(exposed to cigarette smoke) and GEF (exercise protocol on water and exposed to cigarette smoke). On the same day was held the 1st session of the experimental phase of the protocol of exposure to cigarette smoke, which consisted of 30 minutes twice a day, six days a week for three weeks, followed by the first session of the swimming program...

Gravidez na adolescência: determinante para prematuridade e baixo peso

Prematurity and low birth weight are public health problems. This paper aims to relate the occurrence of premature labors and low birth weight with adolescent pregnancy. We performed a literature review about the socioeconomic and cultural conditions of adolescent pregnancy and perinatal results. Through bibliographical data, we identified observational and systematic review articles that deal with the subject. The literature analysis permits us to conclude that adolescent pregnancies as well as the socioeconomic and cultural environment in which the young mother is inserted are associated with the increased frequency of prematures and low birth weight babies. The development and the implementation of effective public policies directed to that population are necessary to a better approach of the problem.

Practices of use of nasal intermittent positive pressure ventilation (NIPPV) in neonatology in northeastern Brazil

Objective: To investigate the use of nasal intermittent positive pressure ventilation (NIPPV) in level three neonatal intensive care units (NICU) in northeastern Brazil. Methods: This observational cross-sectional survey was conducted from March 2009 to January 2010 in all level three NICUs in northeastern Brazil that are registered in the Brazilian Registry of Health Establishments (Cadastro Nacional de Estabelecimentos de Saude, CNES) of the Ministry of Health. Questionnaires about the use of NIPPV were sent to the NICU directors in each institution. Statistical analysis was conducted using the software Epi-Info 6.04 and double data entry. A chi-square test was used to compare variables, and the level of statistical significance was set at p <= 0.05. Results: This study identified 93 level three NICUs in northeastern Brazil registered in CNES, and 87% answered the study questionnaire. Most classified themselves as private institutions (30.7%); 98.7% used NIPPV; 92.8 % adapted mechanical ventilators for NIPPV and used short binasal prongs as the interface (94.2%). Only 17.3% of the units had a protocol for the use of NIPPV. Mean positive inspiratory pressure and positive end-expiratory pressure were 20.0 cmH(2)O (standard deviation [SD]: 4.47) and 5.0 cmH(2)O (SD: 0.84). Conclusion: NICUs in northeastern Brazil use nasal intermittent positive pressure ventilation, but indications and ventilation settings are not the same in the different institutions.

Equity and women's health services for contraception, abortion and childbirth in Brazil

This paper addresses equity in health and health care in Brazil, examining unjust disparities between women and men, and between women from different social strata, with a focus on services for contraception, abortion and pregnancy. In 2010 women's life expectancy was 77.6 years, men's was 69.7 years. Women are two-thirds of public hospital services users and assess their health status less positively than men. The total fertility rate was 1.8 in 2011, and contraceptive prevalence has been high among women at all income levels. The proportion of sterilizations has decreased; lower-income women are more frequently sterilized. Abortions are mostly illegal; women with more money have better access to safe abortions in private clinics. Poorer women generally self-induce abortion with misoprostol, seeking treatment of complications from public clinics. Institutional violence on the part of health professionals is reported by half of women receiving abortion care and a quarter of women during childbirth. Maternity care is virtually universal. The public sector has fewer caesarean sections, fewer low birth weight babies, and more rooming-in, but excessive episiotomies and inductions. Privacy, continuity of care and companionship during birth are more common in the private sector. To achieve equity, the health system must go beyond universal, unregulated access to technology, and move towards safe, effective and transparent care. (C) 2012 Reproductive Health Matters

Perinatal and early life factors associated with symptoms of depression in Brazilian children

Background: Few studies have been conducted on the association between perinatal and early life factors with childhood depression and results are conflicting. Our aim was to estimate the prevalence and perinatal and early life factors associated with symptoms of depression in children aged 7 to 11 years from two Brazilian birth cohorts. Methods: The study was conducted on 1444 children whose data were collected at birth and at school age, in 1994 and 2004/2005 in Ribeirao Preto, where they were aged 10-11 years and in 1997/98 and 2005/06 in Sao Luis, where children were aged 7-9 years. Depressive symptoms were investigated with the Child Depression Inventory (CDI), categorized as yes (score >= 20) and no (score < 20). Adjusted and non-adjusted prevalence ratios (PR) were estimated by Poisson regression with robust estimation of the standard errors. Results: The prevalence of depressive symptoms was 3.9% (95% CI = 2.5-5.4) in Ribeirao Preto and 13.7% (95% CI = 11.0-16.4) in Sao Luis. In the adjusted analysis, in Ribeirao Preto, low birth weight (PR = 3.98; 95% CI = 1.72-9.23), skilled and semi-skilled manual occupation (PR = 5.30; 95% CI = 1.14-24.76) and unskilled manual occupation and unemployment (PR = 6.65; 95% CI = 1.16-38.03) of the household head were risk factors for depressive symptoms. In Sao Luis, maternal schooling of 0-4 years (PR = 2.39; 95% CI = 1.31-4.34) and of 5 to 8 years (PR = 1.80; 95% CI = 1.08-3.01), and paternal age < 20 years (PR = 1.92; 95% CI = 1.02-3.61), were independent risk factors for depressive symptoms. Conclusions: The prevalence of depressive symptoms was much higher in the less developed city, Sao Luis, than in the more developed city, Ribeirao Preto, and than those reported in several international studies. Low socioeconomic level was associated with depressive symptoms in both cohorts. Low paternal age was a risk factor for depressive symptoms in the less developed city, Sao Luis, whereas low birth weight was a risk factor for depressive symptoms in the more developed city, Ribeirao Preto.

Porphyromonas gingivalis infection at different gestation periods on fetus development and cytokines profile

Oral Diseases (2012) 18, 648654 Aim: Infective agents may affect pregnancy outcomes by deregulating homeostasis. Objectives: The effects of Porphyromonas gingivalis infection before and at different gestation periods were evaluated. Materials and Methods: Wistar rats infected via subcutaneous with P. gingivalis W83, one week before mating (BM), days 1 (PR1) and 11 of gestation (PR11), and controls were evaluated, and samples were obtained at the end of gestation. P. gingivalis was detected by PCR. Cytokine was determined by ELISA. Results: Infected rats had lower maternal gain of weight. Implantation was not observed in 2/12 BM rats. PR11 presented more fetal-placental resorptions and lower placenta/fetus weight than controls. P. gingivalis was detected in placenta and fetus. IL-6 and TNF-a levels were higher in placenta and serum of infected groups, except for TNF-a in placenta of PR1. IL-1 beta levels were higher in placenta of PR11, but lower in serum and placenta of PR1. There were no differences in IL-10 and PGE2 concentrations among the groups (P < 0.05). Conclusions: The experimental infection by P. gingivalis resulted in alterations in the gestational pattern and in fetal development. The consequences of infection at mid-gestation were more severe than at the beginning, possibly due to the induction of pro-inflammatory cytokines in the fetal compartment.
