Filter by:Despite public campaigns to prevent cigarette smoking, it's about 20% of women who keep on smoking during pregnancy, exposing their fetus to prenatal tobacco adverse effects. Although environnemental tobacco smoke exposure effects are well known, consequences of prenatal tobacco smoke exposure (PTSE) need better caracterization. Previous animal study from our group have shown, in prenatal nicotine exposed mouse pups, alterations in tracheal epithelial structure similar to those observed in KO α7-nAChR mouse pups. These findings support the hypothesis that α7-nAChR are involved in the process of deleterious effects of tobacco smoking on respiratory epithelium development. The purpose of the present clinical study is to compare PTSE neonates with controls according to lung function and respiratory epithelial functionality. At the age of 3 days, small respiratory epithelium fragments will be obtained from gentle nasal brushing performed under antalgic premedication according to the method we previously published. Epithelium samples will be used for in vitro studies of α7-nAChR and CFTR functionality. Between the ages of 2 and 6 weeks, lung function testing will be performed, by means of baby-body plethysmography.
This prospective and observational trial over 55 pregnant women (third trimester) compares non invasive haemodynamic monitoring using Nexfin technology and ultrasonography technic
Background: Maternal obesity is associated with higher risks of adverse maternal and fetal complications, but the effects of dietary and lifestyle interventions on gestational weight gain(GWG) and pregnancy outcomes in obese pregnant women are unclear. Objective: This study examined whether intensive dietary and lifestyle interventions initiated in the early pregnancy could decrease GWG, and prevent relevant adverse pregnancy outcomes in Chinese obese pregnant women. Design:A randomized controlled trial in obese pregnant women was performed at 6-12 weeks of gestation.The sample size was estimated using GWG reduction as the primary outcome variable. The investigators pilot study (data not published) showed the gestational weight gain was 12.73±5.97 for obese women. Assuming intervention may result in 25% (3.1825g) reduction in GWG, the estimated sample size with 90% power and type I error of 0.05 was 114 women in intervention group and 57 in control group. Adjusting for 15% refusal or loss to follow up during pregnancy, the total sample size required was 136 women in intervention group and 68 in control group(standard care group). Participants were randomly assigned to the control or the intervention group. The intervention focused on restricting energy intake combined with behavioral lifestyle modification through participation in group sessions and individual counseling. The primary outcomes were gestational weight gain (GWG) and secondary outcomes were the incidence of gestational diabetes mellitus (GDM), hypertensive disorders during pregnancy, large-for-gestational-age (LGA) infants, macrosomia and the rate of caesarian section. Hypothesis:The intensive dietary and lifestyle intervention performed from the first trimester in obese women could decrease total GWG,and perhaps improve relevant pregnancy outcomes.
It is well known that being overweight or obese increases the risk of health problems, and that many people find it difficult to maintain a healthy weight. Worryingly the rise in obesity is greater in women than in the male population. One possible reason for this is that some women gain too much weight during their pregnancy and find it difficult to lose this weight after the birth of their baby. For example, women who gain more weight than recommended during pregnancy have been shown to be more likely to carry excess that weight at 1 and 15 years after pregnancy, compared to women who gained the recommended amount of weight. There are currently no evidence-based guidelines in the UK for how weight should be managed during pregnancy. For these reasons, it is really important that we understand the factors affecting weight management before, during and after pregnancy. The aim of this research is therefore to find successful approaches to help women manage their weight before, during and after pregnancy. This will be completed by understanding the knowledge, attitudes, experiences and expectations of women during and after pregnancy and to identify the factors (e.g. diet, physical activity, poor social network etc.) which influence body weight. This will enable us to suggest better strategies for promoting healthy weight changes during and after pregnancy.
A double-blinded randomised control trial conducted in the Department of Obstetrics and Gynaecology of a tertiary hospital, Universiti Kebangsaan Malaysia Medical Centre (UKMMC) for two years duration from January 1st, 2012 till December 31st, 2013. The aim of the study is to compare the haemodynamic and cardiovascular effects between intravenous carbetocin 100 μg and intravenous oxytocin 5 IU in women undergoing elective Lower Segment Caesarean Section (EL LSCS). Study hypothesis: A single injection of carbetocin is haemodynamically and cardiovascularly safe and has similar efficacy in comparison to a single injection of oxytocin.
This is a prospective, double-blind placebo-controlled randomized pilot trial of the preliminary safety and efficacy of bupropion SR in combination with behavioral counseling for smoking cessation during pregnancy.
Objective: To assess the relationship between maternal cardiovascular capacity and aerobic water exercise during the gestational periods of hemodynamic overload. Study design: randomized clinical trial, with 41 healthy pregnant women assigned to one of two groups: Control and Water exercise. Maternal cardiovascular capacity (maximum oxygen consumption, cardiac output, stroke volume, heart rate and mean arterial pressure), physical performance (relative HR, treadmill speed and self-perceived exertion) and neonatal outcome (gestational age, weight, Apgar index and length of infant's hospitalization) were assessed. Means were evaluated by dependent and independent t-tests, and proportions by the chi-square method (p<0.05). Results: The control variables showed that the groups were homogeneous. Water exercise was associated with maintenance of VO2max, increase in stroke volume and cardiac output, and better performance on stress tests in the third trimester of gestation. No significant difference in neonatal variables was observed. Conclusion: Water exercise maintained cardiovascular capacity and performance under submaximal stress, and did not affect hemodynamic adaptation to gestation or neonatal outcome.
The purpose of this study is to determine if the presence of fetal fibronectin in the cervicovaginal secretions of pregnant patients with minor maternal trauma predicts impending preterm delivery due to abruptio placenta.
The purpose of this study is to evaluate the immediate effects of carbetocin and oxytocin on maternal hemodynamic parameters (heart rate and blood pressure) in a non-invasive setup (TaskeForce®-Monitor) during primary Caesarean section.
The Prevention Agent Pregnancy Exposure Registry, also known as EMBRACE (Evaluation of Maternal and Baby Outcome Registry After Chemoprophylactic Exposure) is a prospective observational cohort investigation of exposures to study agents under investigation for HIV prevention. The study population will consist of female participants who are identified as becoming pregnant during their participation in a microbicide or PrEP trial, or who have had planned exposures in pregnancy safety studies as well as their babies resulting from these pregnancies. This study will only enroll babies who have not yet reached their 1 year birth date.
