The purpose of this feasibility study is to obtain pilot data in preparation for an upcoming R01 submission. The goals of that submission will be to conduct a clinical trial of n-3 LCPUFAs for smoking cessation in pregnant women. For this proposal, the investigators will develop, test, and refine the recruitment strategy and collect data demonstrating the investigators ability to successfully recruit pregnant women who are actively smoking. The investigators will collect side effect, tolerability, and adherence data regarding the intervention. Finally, the investigators hope to gather preliminary effect size data to allow more formal estimates of sample size. The investigators hypothesize that pregnant smokers randomized to n-3 LCPUFA supplementation will have higher smoking cessation rates and less nicotine cravings compared to women allocated to placebo. The investigators intend to use this preliminary data to inform a future randomized, double-blind, placebo-controlled trial of n-3 LCPUFA supplementation for tobacco cessation.
In a region with 15-20% HIV prevalence, an estimated 20% of HIV-uninfected women could have HIV exposures in pregnancy. In a theoretical scenario of perfect PrEP coverage, all women at risk receive PrEP while no women not at HIV risk receive PrEP (Figure 4). With mandatory PrEP given to all women (similar to the approaches used for malaria prophylaxis), all women at risk would be covered but many women not at risk receive unnecessary PrEP. Our premise is that a targeted PrEP model may be closer to perfect coverage than a universal offer/self-select model. Implementing targeted PrEP through strategies that include facilitation of partner testing with self-tests could add HIV prevention benefit by increasing partner HIV diagnosis and treatment similar to the initiation of PrEP among pregnant women. By implementing these strategies and measuring uptake, use, and HIV incidence, we can inform the best health systems model for PrEP delivery in pregnancy.
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.
