Sialidase activity in aerobic vaginitis is equal to levels during bacterial vaginosis

Objective: To evaluate levels of proinflammatory cytokines and sialidase activity in aerobic vaginitis (AV) in relation to normal vaginal flora and bacterial vaginosis (BV). Study design: In this cross-sectional study, a total of 682 consecutive non-pregnant women attending the gynecology service were assessed and 408 women were included. Vaginal rinsing samples were collected from 223 women with microscopic finding of BV (n = 98), aerobic vaginitis (n = 25) and normal flora (n = 100). Samples were tested for interleukin (IL)-1β, IL-6, IL-8, tumor necrosis factor (TNF)-α, and sialidase activity. Results: Compared to women with normal flora, vaginal levels of IL-1β were highly increased in both BV and AV (p < 0.0001). Significantly higher vaginal IL-6 was detected in AV (p < 0.0001) but not in BV, in relation to normal flora. Women with AV also presented increased IL-8 levels (p < 0.001), while those with BV presented levels similar to normal flora. Sialidase was increased in BV and AV compared with the normal group (p < 0.0001) but no difference in sialidase activity was observed between BV and AV. Conclusion: A more intense inflammatory host response occurs for AV than for BV when compared with normal flora. Furthermore, the increased sialidase activity in AV and BV indicates that both abnormal vaginal flora types can be harmful to the maintenance of a healthy vaginal environment. © 2012 Elsevier B.V.

Gestantes vivendo com HIV/AIDS: Características antropométricas e peso ao nascer dos seus recém-nascidos

PURPOSE: To describe the anthropometric and pregnancy characteristics of women with HIV/AIDS, assisted by the Brazilian National Health System and the birth weight of their newborns. METHODS: The participants were women assisted at public STD/AIDS clinics of the Municipal Health system of São Paulo. The anthropometric characteristics were evaluated by trained nutritionists and other information was obtained from the medical records. For comparison of the survey data to those of the general population, secondary maternal and pregnancy data were obtained from live birth certificates through the Live Birth Information System. Continuous variables were summarized as mean and standard deviation or as the 25th, 50th and 75th percentiles and minimum and maximum values. The other variables are presented as percentages. Means were compared by the Student's t-test or Kruskal-Wallis test depending on the fulfillment of assumptions, with the decision based on the p value. RESULTS: We found the presence of inadequate maternal nutrition according to triceps skinfold (60.9%). The BMI/gestational age showed the presence of underweight (18.5%) and overweight or obesity (40%). There was no association between disease status (HIV or AIDS) and weight, height, and lean or fat mass. Mean newborn birth weight was lower than the value for the general population without infection or disease. The results of this study indicate the need to develop adapted curves to allow a more accurate nutritional assessment of this population group.

Polymorphisms of the adiponectin gene in gestational hypertension and pre-eclampsia

Adiponectin is a hormone involved in energy homeostasis by regulating glucose and lipid metabolism. In addition, the adiponectin gene (ADIPOQ) has polymorphisms that can modulate the circulating concentration of adiponectin. Abnormal adiponectin levels have been associated with pre-eclampsia (PE); however, the influence of genetic polymorphisms on the development of hypertensive disorders of pregnancy is unclear. The aim of this study was to examine whether ADIPOQ polymorphisms are associated with gestational hypertension (GH) and/or PE. We studied 401 pregnant women: 161 healthy pregnant (HP), 113 pregnant with GH and 127 pregnant with PE. ADIPOQ polymorphisms -11391G>A (rs17300539), -11377C>G (rs266729), 45T>G (rs2241766) and 276G>T (rs1501299) were genotyped by allelic discrimination assays using real-time PCR. Haplotypes were inferred using the PHASE 2.1 program. We observed that the genotypic frequencies of the -11377C>G polymorphism were different in PE compared with HP (P<0.0125), with the CT genotype being more commonly found in PE patients than in HP women (P<0.0125). However, allelic frequencies of this single-nucleotide polymorphism were similar between PE and HP (P>0.0125). No difference was observed when GH and HP groups were compared (both P>0.0125). In addition, we found no difference in genotype or allele distributions for the -11391G>A, 45T>G and 276G>T polymorphisms when we compared GH or PE with HP (all P>0.0125). In conclusion, we found a modest association between the CG genotype of the -11377C>G polymorphism and PE.Journal of Human Hypertension advance online publication, 27 June 2013; doi:10.1038/jhh.2013.53.

Diabetic rats exercised prior to and during pregnancy: Maternal reproductive outcome, biochemical profile, and frequency of fetal anomalies

The aim of this study was to evaluate the effects of exercise prior to or during pregnancy on maternal reproductive outcome, biochemical profile, and on fetal anomaly frequency in a rat pregnancy model utilizing chemically induced diabetes. Wistar rats (minimum n = 11 animals/group) were randomly assigned the following groups: group 1 (G1), sedentary, nondiabetic; G2, nondiabetic, exercised during pregnancy; G3, nondiabetic, exercised prior to and during pregnancy; G4, sedentary, diabetic; G5, diabetic, exercised during pregnancy; and G6, diabetic, exercised prior to and during pregnancy. A swimming program was utilized for moderate exercise. On day 21 of pregnancy, all rats were anesthetized to obtain blood for biochemical measurements. The gravid uterus was weighed with its contents, and the fetuses were analyzed. The nondiabetic rats exercised prior to pregnancy presented a reduced maternal weight gain. Besides, G2 and G3 groups showed decreased fetal weights at term pregnancy, indicating slight intrauterine growth restriction (IUGR). In the diabetic dams, the swimming program did not have antihyperglycemic effects. The exercise applied only during pregnancy caused severe IUGR, as confirmed by reduced fetal weight mean, fetal weight classification, and ossification sites. Nevertheless, exercise was not a teratogenic factor and improved the rats' lipid profiles, demonstrating that the exercise presented possible benefits, but there are also risks prior and during pregnancy, especially in diabetic pregnant women. © The Author(s) 2012.

Qualidade de vida em gestantes com cardiopatia

The objective of this cross-sectional, descriptive and exploratory study was to describe the perceptions of pregnant women with heart disease concerning their quality of life. Ferrans and Powers Quality of Life Index was applied to 42 patients from the second trimester of pregnancy on, between January 2008 and March 2009. Descriptive statistics, analysis of variance and Student's t test were used. The Quality of Life Index median total score was relatively high (23.9), while the socioeconomic domain was the most compromised (22.9). An association between unplanned pregnancies and the socioeconomic domain was observed (p=0.065). These patients' quality of life can be regarded as good, but unplanned pregnancies contributed to worsening scores in the socioeconomic domain. High-risk pregnancies did not affect quality of life because a pregnancy is linked to meanings such as happiness, satisfaction and personal fulfillment.

Desmame precoce: Falta de conhecimento ou de acompanhamento?

Objective: To assess the knowledge of women and the instructions received on breastfeeding during pregnancy and after childbirth, and their influence on breastfeeding practice. Method: This study was a longitudinal investigation following 84 pairs of mothers and babies from pregnancy through the sixth month of baby's life. In the first phase of the research, interviews were made with the pregnant women at home and at Basic Health Units to collect information about their intentions and knowledge of breastfeeding. In the second phase of the research, mothers and babies were followed up from the first to sixth month of baby's life to record the difficulties of breastfeeding and reasons for weaning. Results: In the first month, 94.3% (82) of the babies were breastfed, but only 49.4% (43) were breastfed exclusively. At the end of the sixth month of life, 43.7% (38) of the babies had already been weaned. No mother breastfed exclusively her baby within the sixth month. During pregnancy, 60.7% (51) of the mothers had no instructions about breastfeeding and 83.4% (70) of the mothers received instructions on breastfeeding after childbirth. Most mothers (76.2%) knew about the ideal breastfeeding period. Seventy-three (86.9%) mothers believed that breastfeeding was beneficial for the baby, but only 41 (48.8%) of them really breastfed. Only 11 (13.1%) mothers were followed up by the public health system team during lactation. Conclusion: Although most women had been instructed during pregnancy or after childbirth and had knowledge of breastfeeding, early weaning occurred. Advising is important, but the support and follow up of the mothers are of utmost importance for a successful breastfeeding practice.

Maternal flow-mediated dilation and nitrite concentration during third trimester of pregnancy and postpartum period

Objectives. To compare maternal flow-mediated dilation (FMD) of the brachial artery and nitrite concentration between third trimester of pregnancy (3rdT) and postpartum (PP) period. Additionally, we will evaluate whether FMD correlates with nitrite concentration in both periods. Methods. Eligibility criteria was healthy women with singleton pregnancy, gestational age >28 weeks, nonsmokers, and no personal or family history of vascular disease. Each women was examined during 3rdT and between 8 and 12 weeks PP to evaluate FMD and nitrite concentration in whole blood. Women not examined in both periods were excluded. Values between both periods were compared using paired t tests. Correlation between FMD and nitrite was examined by Pearson correlation coefficient. Significance level set as p<0.05. Results. We invited 42 pregnant women. Among them, 35 were eligible and 7 of them were excluded for not attending the PP evaluation resulting in 28 participants analyzed. We found no significant change in FMD (10.39±5.57% vs. 8.42±4.21%; p=0.11; 3rdT vs. PP, respectively) and no significant change in nitrite concentration (257.41±122.95nmol/L vs. 237.16±90.01nmol/L; p=0.28). Baseline brachial artery diameter had a significant reduction (3.11±0.30 to 2.75±0.34mm; p<0.01). No significant correlation between FMD and nitrite during 3rdT (r=-0.13; p=0.50) or PP (r=0.14; p=0.48) was found. Conclusions. We did not observe significant changes in both FMD and nitrite concentration between third trimester and the PP period. FMD did not correlate with nitrite in both periods. More studies are needed to confirm our findings. © Informa Healthcare USA, Inc.
