Filter by:The purpose of this study is to compare the sensitivity and the specificity of electrical cardiometry to the lung ultrasound in measuring thoracic lung water in pregnant females with pre-eclampsia. If electrical cardiometry is validated against ultrasound, it will be easy to use with numerical number that will not require advanced experience as with the ultrasound.
the investigators assume that magnesium sulphate for treating eclampsia can be safely reduced from 24 hours to shorter duration of therapeutic anticonvulsant effect for 12 hours. Short duration of drug exposure is suitable for low resource setting where there is little tools or busy staff for monitoring drug toxicity.
Normal pregnancy is associated with vasodilation and decreased peripheral resistance, which is detected as early as 5 weeks' gestation . Pre-eclampsia is a multi-system disorder of the second half of pregnancy , which is characterized by increased vascular reactivity and peripheral resistance with pathological changes that are consistent with impaired blood flow to the affected vascular beds. Investigators will evaluate fetal and maternal vascular changes in normotensive and pre-eclamptic patients by Ultrasound and Doppler and their impact on prediction of pregnancy outcome.
To determine if the use of impedance cardiography can identify appropriate medications for use in treating morbidly obese patients to decrease the risk of preeclampsia.
Vitamin D deficient pregnant ladies were selected and randomized into 2 groups for routine daily dose of multivitamin (400IU vitamin D3) versus maximum safest treatment daily dose (4000IU vitamin D3). Participants were assessed and compared for number of pre-eclampsia cases.
Background: The purpose of this study is to examine the relationship between maternal preeclampsia and periodontal parameters and the correlation of these two disorders with maternal gingival crevicular fluid levels (GCF) of interleukin (IL)-35, interleukin-37 and interleukin-6. The investigators also investigated their relation to the severity of preeclampsia. Methods: 82 preeclamptic women were recruited to the study (29 healthy pregnant women, 30 mild preeclamptic patient, 23 severe preeclamptic patient ). The clinical periodontal parameters and GCF samples were collected in the first day of puerperium.
Toxemia of pregnancy is a recognized entity for over 2000 years with its known complications and fatality. Nowadays, a most accepted terminology for the following defined syndrome is "hypertensive disorders in pregnancy" given by American College of Obstetrics and Gynecology. It is an important cause of maternal and fetal morbidity and mortality. Pregnancy induced hypertension (PIH) was classified as gestational hypertension, preeclampsia, severe preeclampsia and eclampsia. PIH is a hypertensive disorder in pregnancy that occurs after 20 weeks of pregnancy in the absence of other causes of elevated blood pressure (BP) (BP >140/90 mmHg measured two times with at least of 4 hour interval) in combination with generalized edema and/or proteinuria (>300 mg per 24 hrs). When there is significant proteinuria it is termed as preeclampsia; seizure or coma as a consequence of PIH is termed as eclampsia. Preeclampsia was classified into mild and severe preeclampsia. Mild eclampsia—BP >140/90 mmHg, proteinuria+, and/or mild edema of legs, Severe preeclampsia—BP >160/110 mmHg,proteinuria++ or ++++, headache, cerebral or visual disturbances, epigastric pain, impaired liver function tests and increase in serum creatinine. Proteinuria was tested using dipstick method as +=0.3 gm/L, ++=1 gm/L, and +++=3 gm/L. The pathological changes of this disease appear to be related to vascular endothelial dysfunction and its consequences (generalized vasospasm and capillary leak). Ocular involvement is common in PIH.Common symptoms are blurring of vision, photopsia, scotomas and diplopia. Visual symptoms may be the precursor of seizures.Progression of retinal changes correlates with progression of PIH and also with the fetal mortality due to similar vascular ischemic changes in placenta.Vasospastic manifestations are reversible and the retinal vessels rapidly return to normal after delivery. Ophthalmoscope should be rated next to the sphygmomanometer as an instrument of diagnostic importance in cases of PIH. Ophthalmoscopy does not only helps in diagnosing the disease but repeated observations assist in assessing the severity, progress of disease, response to treatment if any and ultimate outcome or prognosis.
Investigators will test a novel system of integrated care, to promote the use of the WORLD HEALTH ORGANIZATION Guidelines for the management of pre-eclampsia and initiate the use of a structured risk assessment strategy to reduce the incidence of preterm delivery from pre-eclampsia by providing obstetricians with the confidence to safely defer delivery of women with pre-eclampsia, identified to be of low risk.
Preterm birth (PTB), preeclampsia (PE), fetal growth restriction (FGR) and intra-uterine fetal death (IUFD) constitutes the main causes of perinatal morbidity and mortality and are called "Great Obstetrical Syndromes". Algorithms to predict those outcomes have been developed by combining maternal characteristics (history, age, BMI, blood pressure), biochemical (sFlt-1, β-hCG, PlGF, AFP) and sonographic (uterine artery Doppler, 3D of placenta, cervical length, nasal bone measurement, nuchal translucency) markers. Another prospective observational study ("PREDICTION study" NCT 02189148) is also ongoing, which aims to validate those algorithms at the first trimester of pregnancy. Recent data suggest that repeating the same measurements later in pregnancy could improve the detection rates, allowing closer monitoring of high-risk patients and potential therapeutics under investigation. The current study (PREDICTION2) is an ancillary study of PREDICTION and aims at validating the use of these markers in a combined iterative manner in the prediction of preeclampsia and other obstetrical outcomes.
Preeclampsia (PE) is one of a common type of hypertensive disorder complicating pregnancy (HDCP). It is a class of clinical syndromes which shows relevant symptoms, hypertension and proteinuria after 20 weeks pregnant as main characteristic, and may accompany with fetal anomaly and systemic multi-system organs damage. Several complications, such as eclamptic seizures, coma, intracranial hemorrhage (ICH), cardiac failure, pneumonedema, hepatic failure, kidney failure, placental abruption and disseminated intravascular coagulation (DIC), may be threat to the life of the mother as well as fetal. Thus, the disease is one of the core issues that cause the maternal and perinatal death. Morbidity of PE is approximately 3% to 5%. Morbidity has significant differences between different populations. According to the data, from 1995 to 2004, HDCP morbidity in four hospitals in Guangzhou was 5.78%, and in the HDCP, mild preeclampsia and severe preeclampsia were accounted for 72.22% and 27.78% respectively. Meanwhile, HDCP morbidity decreased from 9.4% (1984 to 1989) to 5.57% (1989 to 1998). In 1996, the American Congress of Obstetricians and Gynecologists (ACOG) gave new classification of HDCP based on the characteristic of disease symptoms, divide into five groups; gestational hypertension, preeclampsia, eclampsia, chronic hypertension complicated with preeclampsia and chronic hypertension. The pathogenesis of PE remains unclear so far. The frequent sight is that PE caused by multiple reactions by a number of factors affect. Physiologically, mainly altered of PE is increased blood viscosity and systemic vascular spasm which cause hypoxic-ischemic of multiple key organs, such as the placenta, kidney, liver and brain. The research theory includes abnormal trophoblast invasion, immune response abnormal or increase, genetic susceptibility, coagulation disorders or thrombophilia, abnormal angiogenesis, endothelial cell damage, abnormal levels of carbonic oxide, increase of oxygen radical, abnormal metabolism of calcium ion, heterotrophia and so on. However, there are numbers of epidemiologic study have analyzed high risk factor of PE which provides significant medical evidence of prevention, early diagnosis and early treatment for PE, there is only little study focus on susceptibility gene and pathogenic genetic variation. Nowadays, there are numerous clinical phenotype are considered to exist, different phenotype gives different inheritance and epigenetics. Thus, our group will examine the onset of type and characteristics of PE by a retrospective cohort study to discuss if susceptibility gene and pathogenic genetic variation were existing in PE patients, also to find the relativity between clinical phenotype and genotype. Moreover, this study is trying to reach the effect of PE on the patients' health as well as their children. Thus, can predict the health status of PE patients and their children, and so can prevent (avoid or delay) of the patients from late complications and disease in their children.
