Insulin Resistance and Hypertensive Disorders in Pregnancy

Hypertension in PregnancyDiabetes Mellitus in Pregnancy

The purpose of this study is to determine whether insulin resistance might affect the pathogenesis of hypertensive disorders in pregnancy since midtrimester. Furthermore, markers of vascular and placental injuries, of oxidative stress and inflammation will be evaluated.

Bedside Monitoring to Identify Impaired Cerebral Autoregulation in Women With Postpartum Hypertension...

PreeclampsiaHypertension in Pregnancy

The purpose of this research study is to develop a protocol for NIRS-based bedside monitoring to identify impaired cerebral autoregulation in women admitted to the high-risk obstetrics unit with postpartum hypertension. The investigators will then pilot this protocol in 10 patients with high-risk neurological features, such as headache.

Drinking Water PFAS, Pregnancy Outcome and Maternal Morbidity

Birth WeightSmall for Gestational Age at Delivery6 more

The aim of the project is to assess the association between exposure to per- and polyfluoroalkyl substances (PFAS) via drinking water in pregnancy and birth outcomes (i.e. growth retardation, premature birth, and congenital developmental defects) and maternal morbidity (gestational hypertension, diabetes and preeclampsia) in a prospective population-wide register study.

Free DNA and Nucleosome Concentrations in Pathological Pregnancies

PregnancyVenous Thrombosis8 more

The primary objective of this study is to demonstrate that plasma concentrations of nucleosomes and free DNA differ between three groups: pregnant patients with complications typical of placental insufficiency or venous thrombosis (group P), healthy women (Group T1) and healthy pregnant women (Group T2).

Kidney Injury Biomarkers in Preeclampsia

HypertensionPregnancy-Induced

we found different pattern of podocyte glycoproteins and kidney injury biomarkers in urine specimens between preeclampsia and pregnancy complicated with chronic hypertention compared with normotensive pregnant controls.abnormally elevayed urine biomarkers in severe preeclampsia were completely or prtially reduced 6-8 weaks after delivery to levels comparable with those of normal pregnant subjects.

Oxfordshire Women and Their Children's Health

PregnancyPre-eclampsia5 more

The aim of this feasibility study is to test recruitment of participants into Phase 1 of the study and then the re-recruitment and retention of participants in Phase 2 of the study. The investigators will also be assessing the acceptability of recruitment strategy and data collection to participants. The effect of pre-pregnancy factors (biophysical, genetic, socioeconomic, behavioural and psychological) on obstetric, cardiovascular, socioeconomic, behavioural and psychological outcomes will all be examined.

Learning to Evaluate Blood Pressure at Home (LEANBH)

Hypertension in Pregnancy

COVID-19 has highlighted important deficiencies in our health service where front line staff and pregnant women are being exposed to SARS-Cov-2 through assessments that could be conducted using Connected Health solutions, reducing risks of contracting or disseminating SARS-Cov-2. Currently, pregnant women are not attending GPs or hospitals for BP monitoring for fear of contracting SARS-Cov-2. Uncontrolled or unmonitored hypertension in pregnancy is associated with maternal and fetal morbidity and mortality. The aim of the study is to use home BP monitoring as an adjunct to standard care for women with borderline/suspected hypertension in pregnancy. To reduce the exposure risk for staff and pregnant women, we propose the immediate implementation of ambulatory automated self BP monitoring using the LEANBH platform- an existing integrated platform to monitor pregnant women.

The Impact of Pregnancy and Pregnancy-associated Hypertension on Human Uterine Myometrial Artery...

PregnancyPreeclampsia1 more

The investigators seek to describe the composition, architecture, and electrical conduction properties of the human uterine myometrial artery and their impact on vascular reactivity upon exposure to hypertensive stress. Non-pregnant women and pregnant women with and without hypertensive complications will be studied to evaluate the influence of these states on the myometrial arteries. Vascular over-reactivity and disruption of the normal pregnancy-associated physiologic changes of relaxed vascular tone possess the potential for non-compensated blood flow to the uterus and placenta that is insufficient to meet the metabolic demands of a growing placenta. With an understanding of these changes, the research team will be able to propose basic mechanistic changes of pathologic myogenic tone that may ultimately be investigated as potentially modifiable processes to reduce the development and/or severity of these pregnancy complications (gestational hypertension, preeclampsia, eclampsia, small for gestational age, intrauterine growth restriction and intrauterine fetal demise. ).

Catestatin and Hypertension in Pregnancy

Pre-EclampsiaEclampsia3 more

Catestatin is a kind of protein involved with cardiovascular disease. Accumulated evidence shows that Catestatin may be a predictor of primary hypertension, but whether it plays the same role in pregnant hypertensive disorders needs to be determined. By measuring the plasma level of Catestatin, main biochemical marks and UCG in healthy pregnancy and pregnancy with hypertension, the research may contribute to this problem.
