The most important guideline for drug prescription concerning pregnant women is 'drugs should be given only if the maternal benefits outweigh the potential risk to the fetus'. However, poor data is available on maternal drug disposition and transfer through the placenta, so the evidence available for decision making in clinical practice is weak. An ex-vivo placenta perfusion model will be used to explore the mechanisms governing differences between fetal and maternal drug exposure. The expression of placental transporters and cytochrome P450 (CYP) enzymes will be investigated in primary placenta cell culture and placental biopsies from different gestational stages to learn how the placental drug transfer and disposition is regulated. The investigators choose to examine the transfer of paracetamol, erythromycin and azithromycin because these drugs are commonly used in human pregnancies and have different metabolic pathways.
This study measures the plasma half-life of 25-hydroxyvitamin D3 (25(OH)D3) in non-pregnant-non-lactating women, pregnant women at 30 wk gestational age and at 3 months post-partum in women who are exclusively breast-feeding.
About 1 in 6 deliveries in KKH are induced with prostaglandins. Inpatient induction can be a lengthy process especially when cervical priming is required. Although mechanical method of induction of labour (IOL) is established, its use in Singapore is uncommon. Systematic reviews comparing mechanical method against pharmacological and surgical IOL showed that mechanical method has similar efficacy with lower risk profile. As IOL is a common obstetric procedure, a revisit on the techniques is warranted. A multi-centre randomised controlled trial concluded that both cervical ripening balloon and prostaglandin are effective and complementary methods for IOL in uncomplicated singleton pregnancies, but did not examined the effects of pain. The investigators propose to evaluate the adverse events in the 12 hours after CRB or 1st prostaglandin insertion, its efficiency in term singleton IOL in Singapore context and test the acceptability of women in Singapore in using the CRB as an alternative method of induction of labour while using a non-incremental balloon filling regime. Currently, there is no efficient method of induction that can be used safely in an outpatient setting. Through this study, the investigators hope to show that there are no major adverse events in the 12h after patients are induced with CRB, this potentially supports outpatient IOL with CRB which can reduce hospitalisation and medical costs. A non-incremental balloon filling regime will decrease time delays and may increase patient satisfaction during its use in induction of labour.
This study evaluate the rate of nausea and nutritional status in patients with hyperemesis gravidarum (severe nausea and vomiting in pregnancy) and healthy pregnant women using a questionnaire (PUQE-score), self-reported food/drink intake form and blood test. The Investigators aim for developing normal range of prealbumin measurements (reference values) during first trimester of pregnancy.
This study is designed to determine the frequency of Tuffier's line overestimation (2 lumbar levels or more) when the palpation method is used in obese parturients at term in the lateral position compared to the sitting position. Hypothesis: The L3-L4 intervertebral space identified by the palpation method will be two levels higher than the level determined by ultrasonography (US) more often in the lateral than in the sitting position.
The objective of this study was the evaluation of periodontal condition in pregnant women and the effect of the treatment of periodontal disease upon low birth weight.
This will be the first study to investigate the use of rTMS in the treatment of neuropathic pain in pregnancy. This study will enroll 60 pregnant subjects, age 18-45. All participants will receive treatment as usual. Subjects diagnosed with neuropathic pain will be offered rTMS as a treatment option.
Maternal smoking during pregnancy (MSDP) increases the risk of adverse pregnancy and birth outcomes and may have long-lasting effects in the offspring.Financial incentives may increase smoking abstinence rate in pregnancy and therefore reduce MSDP related negative health effects. This is a randomized open label study comparing financial incentives for smoking abstinence with no financial incentives for smoking abstinence.Research objectives 1. To test the efficacy of financial incentives on smoking abstinence rate among pregnant smokers; 2. To explore the heterogeneity of efficacy according to individual characteristics: socioeconomic status, social background, smoking characteristics, personality traits, time and risk preferences to determine profiles of women which could benefit best from this kind of intervention; 3. To provide a cost-benefit analysis based on the cost of newborn and children disease due to maternal smoking during pregnancy.
Digital vaginal examination is the most common method for assessing progress of labor and delivery. Considering it is the most common intervention women receive during course of labor, evidence for psychological effects of digital vaginal examination on women is surprisingly sparse. Reducing the number of vaginal examination during labor has been proposed by many authors as benefit of more vaginal examination is unclear. However this is unlikely to happen until more research on the topic demonstrates clear detrimental effects of vaginal examination. Our study is aimed at investigating association of vaginal examination with psychological distress of women during labor. Anxiety during labor is associated with longer labor duration, increased perception of pain, problems with newborn attachment, and increased rates of postpartum depression and post-traumatic stress disorder. In this study, women were assigned to either digital vaginal examination or transperineal ultrasound assessment groups were compared to each other in a randomised controlled setting.
