Description of intervention(s) / exposure
This observational study does not include any intervention to routine medical care of the participant.
Participation will involve completion of a questionnaire and collection of 3 blood samples.
The questionnaire will have questions regarding basic demographic information, past medical history, details of previous pregnancy/pregnancies (gestational age at delivery, complications during pregnancy, any antenatal interventions, mode of delivery and birth weight), as well as details of current pregnancy (pregnancy complications, antenatal interventions). This will take 10-15min to complete.
Blood samples will be collected once at time of recruitment, once at development of complications or at 36 weeks gestations, and finally at 6 months post birth.
For this study we will also be collecting de-identified data from participant's medical records. This include demographic details, past medical history, antenatal complications, antenatal interventions, mode of delivery and any peri-partum complications.
The total observational period will be from time of recruitment (at any gestation of pregnancy) until 6 months post delivery.
Intervention code [1] 324546 0
Diagnosis / Prognosis
Comparator / control treatment
The comparator will be participants who are recruited after meeting eligibility criteria (blood pressure >130/80) who have not developed and does not go on to develop any pregnancy complications (hypertension in pregnancy, gestational diabetes, fetal growth restriction, spontaneous preterm birth).
For this group, blood samples will be collected at time of recruitment and at 36 weeks gestation.
Control group
Active

Outcomes
Primary outcome [1] 332678 0
Women with demographic or examination (e.g. elevated BP >=130/80) risk factors who go on to develop pre-eclampsia by current diagnostic criteria of pre-eclampsia (blood pressure >140/90 with evidence of end organ dysfunction).
This will be determined by review of medical records and pathology results. As well as by patient self reporting.
Timepoint [1] 332678 0
This outcome will be determined through weekly review of participant's medical record from time of recruitment until birth to identify the development of pre-eclampsia. Or at any time during this period by patient self report.
Primary outcome [2] 332893 0
Women with pregnancy complications (Gestational diabetes, hypertensive disorder of pregnancy, fetal growth restriction and spontaneous preterm birth) who have persistent derangement in cardio-metabolic markers (HbA1c, Insulin levels, BNP, Lipid profile) 6-12 months post-partum. This will be assessed using blood samples.
Timepoint [2] 332893 0
This outcome will be assessed through blood samples which will be collected once at time of recruitment, once at development of complications or at 36 weeks gestations, and once at 6-12 months post-partum at the convenience of the participant.
Primary outcome [3] 333079 0
Women with elevated blood pressures (>130/80) and/or pregnancy complications (Gestational diabetes, hypertensive disorder of pregnancy, fetal growth restriction and spontaneous preterm birth) who have derangement in placental markers (sFlt, PLGF, sFlt/PLGF ratio), assessed using blood samples.
Timepoint [3] 333079 0
his outcome will be assessed through blood samples which will be collected once at time of recruitment, once at development of complications or at 36 weeks gestations, and once at 6-12 months post-partum at the convenience of the participant.
Secondary outcome [1] 414340 0
Adverse maternal outcomes: This will include a composite of hepatic dysfunction, acute renal insufficiency, placental abruption, acute pulmonary oedema, development of HELLP (Haemolysis, elevated liver enzymes, low platelets) syndrome, need for parenteral antihypertensive medication, need for insulin therapy, admission to intensive care unit, mode of delivery and postpartum haemorrhage.
These outcomes will be assessed by review of participant medical records.
Timepoint [1] 414340 0
This outcome will be determined through review of participant's medical record from the time of enrolment to the time of delivery.
Secondary outcome [2] 415001 0
Adverse perinatal outcomes: This will include a composite of gestation at delivery, birth weight, stillbirth, neonatal death and neonatal morbidity. Neonatal morbidity will be defined as admission to a neonatal special care nursery or intensive care unit for more than 48 hours, respiratory distress syndrome, need for mechanical ventilation, intraventricular haemorrhage, confirmed infection, necrotising enterocolitis, seizures, encephalopathy and retinopathy of prematurity.
Incidence of these perinatal outcomes will be assessed through review of the of participant's newborn's medical records.
Timepoint [2] 415001 0
This outcome will be determined through review of participant's baby's medical record from time of delivery to 28 days after birth.
Secondary outcome [3] 415721 0
Women with elevated blood pressures (>130/80) and/or pregnancy complications (Gestational diabetes, hypertensive disorder of pregnancy, fetal growth restriction and spontaneous preterm birth) who have derangement in endothelial dysfunction markers (ICAM 1, VCAM 1, tumor necrosis factor-alpha) assessed using blood samples
Timepoint [3] 415721 0
This outcome will be assessed through blood samples which will be collected once at time of recruitment, once at development of complications or at 36 weeks gestations, and once at 6-12 months post-partum at the convenience of the participant.

Statistical methods / analysis
For comparison between groups, t-test and/or Mann-Whitney test and binary logistic regression will be used, as appropriate. To test and adjust for potential confounders, logistic regression analysis will be performed. Screening performance will be assessed using sensitivity, specificity, positive and negative predictive values and Receiver Operating Curve (ROC) areas. The analysis will be carried out using SPSS 16.0 (SPSS Inc., Chicago, IL) and Stata (version 12 or later; StataCorp, College Station, Texas, USA). The study will be reported in accordance with STAndards for the Reporting of Diagnostic accuracy studies (STARD) guidelines.
