Kenya is one of the countries in sub-Saharan Africa that still experience high maternal mortality. For instance, in 2008/09 maternal mortality ratio was estimated to be 488/100,000 live births. Direct obstetric complications such as puerperal sepsis, postpartum hemorrhage, pre-eclampsia and eclampsia, obstructed labor and indirect causes including HIV, malaria and anemia in pregnancy are responsible for the majority of these cases. Just under 44% of births in Kenya are delivered under the supervision of a skilled birth attendant. The overall objective of this study is to determine the effect of provider type in the occurrence and management of serious childbirth related complications among postpartum women at the community level in Bungoma and Lugari Districts of Western Province, Kenya. The proposed study will employ a case control study design in which women with obstetric complication(s)will be cases and women without obstetric complications will be controls. Controls will be sampled concurrently with the cases. Each time a new case is diagnosed, a control is selected from the population at risk in the neighborhood at that point in time. The study population will consist of women aged 15-49 years with a delivery in the past 12 months. A woman who reports having experienced a birth-related complication will be recruited as a case while woman who reports having experienced no complication during child-birth will be recruited as a control.
The investigators plan to identify 80 pregnant women at low risk for obstetrical complications and replace 4-5 routine third trimester visits with a structured program of home weight, blood pressure and urine protein monitoring along with regular structured phone interviews and a 28 week ultrasound. The investigators hypothesis is that this protocol is both safe and acceptable.
The purpose of this study is to assess the potential prognostic value of seric concentrations of EG-VEGF for Pre-eclampsia and/or intrauterine growth restriction and will allow checking whether plasma levels of EG-VEGF at 14-18 weeks of gestation could be proposed as prognostic marker for preeclampsia.
Introduction: Hypertensive disorders during pregnancy are an important issue in global public health. It is current the leading cause of maternal mortality in Brazil. Objective: To assess the effect of physical exercise using stationary bicycle through blood pressure and heart rate measurements, incidence of pre-eclampsia and quality of life survey in pregnant women with chronic high blood pressure, previous preeclampsia pregnancies or both factors associated comparing to a group with no intervention. Verify the type of births, maternal and perinatal outcomes in both groups. Methodology: This randomized clinical trial enrolled pregnant women presenting chronic hih blood pressure, previous pre-eclampsia experience or both. Women from 12 to 20 gestational weeks were selected from the prenatal outpatient clinic and randomly allocated to the study or non-interventional group. Women at the study group performed physical exercise using stationary bicycle (horizontal bench model) during 20 minutes, once a week. The heart rate was maintained at 20% above resting heart rate and up to 140 bpm. Blood pressure and heart rate measurements were evaluated before and after exercise. The non-intervention group followed regular prenatal routine with weekly returns for heart rate and blood pressure measurements. Both groups fulfilled the quality of life survey (SF-36 questionnaire) at three times: between 12 and 20 weeks; 28 and 32 weeks and 36 and 41 weeks of gestation. After that data of parturition will be analyzed to compare the incidence of pre-eclampsia, types of birth, maternal and perinatal outcomes.
Placental insufficiency is the source of preeclampsia (PE) and intrauterine growth retardation (IUGR). Current data demonstrate a significant beneficial effect of prophylactic use of aspirin on the recurrence of placental insufficiency and its complications, mainly preeclampsia, when started early in pregnancy. However, there is a significant heterogeneity in medical practice in Canada and around the world in terms of the dose of aspirin used. The objectives of this study are: 1) Evaluate whether a dose of 160 mg of aspirin is associated with greater improvement in placental function assessed by biochemistry (sFlt-1 and endoglin) and ultrasound (uterine artery Doppler) than a dose of 80 mg in women with a history of PE, 2) Assess whether the change is dependent on platelet aggregation measured by a test used in several Canadian centers (PFA-100).
Preeclampsia is associated with significant maternal and fetal morbidity and mortality. Early identification and subsequent management of patients at risk of developing preeclampsia presents an ongoing challenge in prenatal care. Some at risk pregnancies may be identified from: - serum screening abnormalities in the first or second trimester - placental shape and texture at the 18-20 anatomical ultrasound - uterine artery blood flow. Early identification and effective treatment of patients would permit the safe completion of the pregnancy for the mother and infant. Recent advances in non-invasive cardiovascular monitoring have enabled the study of maternal hemodynamics in normal and at-risk pregnancies. This study hopes to identify the earliest significant changes in maternal hemodynamics which may allow targeted therapeutic interventions in patients at high risk of developing preeclampsia. The hypothesis of this study is that systemic vascular resistance rises during the pre-clinical phase of preeclampsia and this can be captured using non invasive bioreactance technology. Treatment of the abnormally high vascular tone may decrease the severity and postpone the onset of clinical disease.
The primary purpose of the trial is to evaluate coagulation activator markers in patients with pre eclampsia compared to control (normal pregnancy) and to correlate these markers with the severity of the pathology.
The utilization of external cardiohemodynamic patient assessment, applying non-invasive stick-on contact patches to the mother's neck on either side and chest wall on either side, enables the practitioner to have information about the patient's cardiac function and vascular status beyond simply blood pressure and pulse. This information, once collected, should open the practitioner's eyes to better assess the patient's disease status and her response to therapy. We will use this information to compare the effectiveness of the two standard medications used for treatment of maternal high blood pressure.
Pre-eclampsia and intra uterine growth restriction (IUGR) represent major complications for pregnant women, with a high related maternal and fetal morbidity and mortality. It is now widely admitted that these pathologies, which can concern up to 7% of pregnancies, are in relation with hypo-perfusion of the placenta because of an early deficient trophoblast invasion and uterine vascular remodelling.Advances in ultrasound imaging now permit non invasive 3D volume and Doppler signal quantification using automatic acquisitions.Quantitative comparison of volumes and Doppler parameters between control pregnancies and IUGR ought to confirm the theory of UTERO-placental hypo-perfusion. This technique might allow an earlier prediction for IUGR. The aim of this study is to evaluate the interest of 3D Doppler quantification as a new screening tool for pre eclampsia and IUGR.
