Arterial Health Markers in Relation to Behavior and Cognitive Outcomes at School Age

BACKGROUND:Impaired arterial health is associated with a decline in cognitive function and psychopathology in adults. We hypothesized that these associations originate in early life. We examined the associations of blood pressure, common carotid artery intima media thickness, and carotid distensibility with behavior and cognitive outcomes during adolescence. METHODS AND RESULTS: This study was embedded in the Dutch Generation R Study, a population-based prospective cohort study from early fetal life onwards. Blood pressure, carotid intima media thickness, and carotid distensibility were measured at the age of 10 years. At the age of 13 years, total, internalizing and externalizing problems and attention-deficit hyperactivity disorder symptoms were measured using the parent-reported Child Behavior Checklist (CBCL/6-18), autistic traits were assessed by the Social Responsiveness Scale, and IQ was assessed using the Wechsler Intelligence Scale for Children-Fifth Edition. A 1-SD score higher mean arterial pressure was associated with lower odds of internalizing problems (odds ratio [OR], 0.92 [95% CI, 0.85-0.99]). However, this association was nonsignificant after correction for multiple testing. Carotid intima media thickness and carotid distensibility were not associated with behavior and cognitive outcomes at 13 years old. CONCLUSIONS: From our results, we cannot conclude that the associations of blood pressure, carotid intima media thickness, and carotid distensibility at age 10 years with behavior and cognitive outcomes are present in early adolescence. Further follow-up studies are needed to identify the critical ages for arterial health in relation to behavior and cognitive outcomes at older ages.</p

Anticorpos anti-célula-endothelial e envolvimento do sistema nervoso central na moléstia de Behçet

INTRODUCTION: Previous studies have detected the presence of anti-endothelial cell antibodies (AECA) in patients with Behçet's disease (BD). However, no real evidence exists whether these antibodies exert any influence on clinical presentation and/or activity of this disease. OBJECTIVES: To determine the frequency of AECA in patients with BD and analyze possible clinical associations. METHODS: 50 patients with BD who fulfilled diagnostic criteria were selected. Thirty-seven patients were females, and 13 were males; the mean age was 44 &plusmn; 9 years with a mean follow-up time of 10 &plusmn; 7.5 years. AECA were assayed by ELISA using ECV-304 cells as the antigenic substrate. The prevalence of AECA was determined, and their possible relationships with present and past clinical features were investigated. RESULTS: AECA were detected in the sera of 38% of the patients (IgG in 13, IgM in four, and IgG plus IgM in two). An association was observed between AECA and a previous history of central nervous system involvement (OR= 5.4, p= 0.03). This association was more evident for IgG-AECA (OR= 6.0, p= 0.02). A trend of an increased risk of aneurysms was also observed in patients with IgG-AECA (OR= 2.58, p= 0.77). None of the other clinical characteristics showed a relevant association with these antibodies. CONCLUSION: Our data suggest that IgG-AECA may be a marker of more severe lesions in patients with BD based on the higher frequency of previous central nervous system manifestations in patients who presently display circulating AECA.INTRODUÇÃO: Estudos anteriores detectaram a presence de anticorpos anti-célula endotelial (AACE) em pacientes com doença de Behçet, porém não há nenhuma evidência se a presença destes anticorpos exerce alguma influência na apresentação clínica ou atividade da doença. OBJETIVOS: Determinar a freqüência de AACE em pacientes com doença de Behçet e analisar possíveis associações clínicas. MÉTODOS: Foram selecionados 50 pacientes que preencheram corretamente os critérios diagnósticos para a doença de Behçet. Trinta e sete pacientes eram do sexo feminino e 13 do sexo masculino, média de idade de 44 &plusmn; 9 anos e tempo médio de seguimento de 10 &plusmn; 7,5 anos. O AACE foram analisados por ELISA utilizando células ECV-304 como substrato antigênico. A prevalência de AACE foi determinada e foram investigadas possíveis relações com características clínicas atuais e pregressas. RESULTADOS: Os AACE foram detectados no soro de 38% dos pacientes (13 na forma IgG, 4 IgM e 2 nas formas IgG e IgM). Observamos uma associação entre o AACE e história pregressa de envolvimento de sistema nervoso central (OR=5,4; p=0,03). Esta associação era mais evidente para o AACE na forma IgG (OR=6,0; p=0,02). Observamos também uma tendência de risco aumentado de aneurismas em pacientes com AACE na forma IgG (OR=2,58; p=0,77). Nenhuma outra característica clínica mostrou-se relevante com o anticorpo estudado. CONCLUSÃO: Nossos dados sugerem que o AACE na forma IgG pode ser uma marcador de lesão mais grave em pacientes com doença de Behçet baseado no fato de encontrarmos uma maior freqüência de história pregressa de manifestação de sistema nervoso central em pacientes com AACE circulante

Maternal cardiovascular adaptation to twin pregnancy: A population-based prospective cohort study

Background: In women with singleton pregnancies, maternal adaptation is considered a stress test for later life cardiovascular disease. The aim of this study was to assess maternal adaptation in women with twin pregnancies compared to women carrying singletons during and after pregnancy. Methods: This was a population based prospective cohort study of 91 women with twin pregnancies and 8107 women carrying singletons. The association of twin pregnancy and maternal adaptation was examined using regression analyses. In pregnancy, we measured soluble fms-like tyrosine kinase-1 (sFLT-1), placental growth (PGF) factor, systolic (SBP) and diastolic blood pressure (DBP), and the occurrence of pre-eclampsia (PE). After pregnancy, measurements were obtained on SBP and DBP, cardiac function, retinal calibres, intima media thickness and distensibility of the common carotid artery. Results: sFLT-1 and PGF concentrations were higher in early (13.4 weeks) and mid-pregnancy (20.4 weeks) in women with twin pregnancies compared to women with singleton pregnancies. Women with twin pregnancies had a different DBP pattern in pregnancy. Women with twin pregnancies were more likely to have PE (odds ratio 3.63; 95% CI [1.76 to 7.48]). Six and ten years after pregnancy, no differences in maternal adaptation were observed. Conclusions: Women with twin pregnancies show an altered adaptation during pregnancy compared to women with singleton pregnancies. This is associated with a substantially increased incidence of PE, but does not lead to persistent altered maternal adaptation years after pregnancy

Fetal sex and maternal pregnancy outcomes: a systematic review and meta-analysis.

BACKGROUND Since the placenta also has a sex, fetal sex-specific differences in the occurrence of placenta-mediated complications could exist. OBJECTIVE To determine the association of fetal sex with multiple maternal pregnancy complications. SEARCH STRATEGY Six electronic databases Ovid MEDLINE, EMBASE, Cochrane Central, Web-of-Science, PubMed, and Google Scholar were systematically searched to identify eligible studies. Reference lists of the included studies and contact with experts were also used for identification of studies. SELECTION CRITERIA Observational studies that assessed fetal sex and the presence of maternal pregnancy complications within singleton pregnancies. DATA COLLECTION AND ANALYSES Data were extracted by 2 independent reviewers using a predesigned data collection form. MAIN RESULTS From 6522 original references, 74 studies were selected, including over 12,5 million women. Male fetal sex was associated with term pre-eclampsia (pooled OR 1.07 [95%CI 1.06 to 1.09]) and gestational diabetes (pooled OR 1.04 [1.02 to 1.07]). All other pregnancy complications (i.e., gestational hypertension, total pre-eclampsia, eclampsia, placental abruption, and post-partum hemorrhage) tended to be associated with male fetal sex, except for preterm pre-eclampsia, which was more associated with female fetal sex. Overall quality of the included studies was good. Between-study heterogeneity was high due to differences in study population and outcome definition. CONCLUSION This meta-analysis suggests that the occurrence of pregnancy complications differ according to fetal sex with a higher cardiovascular and metabolic load for the mother in the presence of a male fetus. FUNDING None

ANÁLISE DA PRESENÇA DE OBESIDADE, COMPORTAMENTOS E FATORES DE RISCO CARDIOVASCULAR EM INDIVÍDUOS HIPERTENSOS

A hipertensão arterial (HA) é o principal fator de risco (FR) para a morbidade e mortalidade precoces causadas por doenças cardiovasculares. O objetivo desse estudo é avaliar a presença de obesidade, comportamentos e FR cardiovascular em indivíduos hipertensos na FCT UNESP de Presidente Prudente. Foram avaliados três comportamentos de risco à saúde: tabagismo, etilismo e sedentarismo, e os fatores de risco avaliados foram obesidade, hipertensão arterial, dislipidemias e diabetes mellitus. O principal achado desse estudo é que há uma alta prevalência da obesidade, comportamentos e FR cardiovascular nesses indivíduos, aumentando a chance de desenvolver doenças cardiovasculares (DCV). Conclui-se que a presença de obesidade, comportamentos e FR cardiovascular em indivíduos hipertensos é elevada, sendo o histórico familiar de DCV e o sedentarismo, o comportamento e o fator de risco mais encontrados respectivamente

Exposure to natural environments during pregnancy and birth outcomes in 11 European birth cohorts

Research suggests that maternal exposure to natural environments (i.e., green and blue spaces) promotes healthy fetal growth. However, the available evidence is heterogeneous across regions, with very few studies on the effects of blue spaces. This study evaluated associations between maternal exposure to natural environments and birth outcomes in 11 birth cohorts across nine European countries. This study, part of the LifeCycle project, was based on a total sample size of 69,683 newborns with harmonised data. For each participant, we calculated seven indicators of residential exposure to natural environments: surrounding greenspace in 100m, 300m, and 500m using Normalised Difference Vegetation Index (NDVI) buffers, distance to the nearest green space, accessibility to green space, distance to the nearest blue space, and accessibility to blue space. Measures of birth weight and small for gestational age (SGA) were extracted from hospital records. We used pooled linear and logistic regression models to estimate associations between exposure to the natural environment and birth outcomes, controlling for the relevant covariates. We evaluated the potential effect modification by socioeconomic status (SES) and region of Europe and the influence of ambient air pollution on the associations. In the pooled analyses, residential surrounding greenspace in 100m, 300m, and 500m buffer was associated with increased birth weight and lower odds for SGA. Higher residential distance to green space was associated with lower birth weight and higher odds for SGA. We observed close to null associations for accessibility to green space and exposure to blue space. We found stronger estimated magnitudes for those participants with lower educational levels, from more deprived areas, and living in the northern European region. Our associations did not change notably after adjustment for air pollution. These findings may support implementing policies to promote natural environments in our cities, starting in more deprived areas

Integrating multiple lines of evidence to assess the effects of maternal BMI on pregnancy and perinatal outcomes

Background: Higher maternal pre-pregnancy body mass index (BMI) is associated with adverse pregnancy and perinatal outcomes. However, whether these associations are causal remains unclear. Methods: We explored the relation of maternal pre-/early-pregnancy BMI with 20 pregnancy and perinatal outcomes by integrating evidence from three different approaches (i.e. multivariable regression, Mendelian randomisation, and paternal negative control analyses), including data from over 400,000 women. Results: All three analytical approaches supported associations of higher maternal BMI with lower odds of maternal anaemia, delivering a small-for-gestational-age baby and initiating breastfeeding, but higher odds of hypertensive disorders of pregnancy, gestational hypertension, preeclampsia, gestational diabetes, pre-labour membrane rupture, induction of labour, caesarean section, large-for-gestational age, high birthweight, low Apgar score at 1 min, and neonatal intensive care unit admission. For example, higher maternal BMI was associated with higher risk of gestational hypertension in multivariable regression (OR = 1.67; 95% CI = 1.63, 1.70 per standard unit in BMI) and Mendelian randomisation (OR = 1.59; 95% CI = 1.38, 1.83), which was not seen for paternal BMI (OR = 1.01; 95% CI = 0.98, 1.04). Findings did not support a relation between maternal BMI and perinatal depression. For other outcomes, evidence was inconclusive due to inconsistencies across the applied approaches or substantial imprecision in effect estimates from Mendelian randomisation. Conclusions: Our findings support a causal role for maternal pre-/early-pregnancy BMI on 14 out of 20 adverse pregnancy and perinatal outcomes. Pre-conception interventions to support women maintaining a healthy BMI may reduce the burden of obstetric and neonatal complications. Funding: Medical Research Council, British Heart Foundation, European Research Council, National Institutes of Health, National Institute for Health Research, Research Council of Norway, Wellcome Trust.</p
