Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Different screening modalities evaluation to develop algorithms to predict pregnancy complications in twin pregnancies, and evaluation of serologic response to BNT162b2 Pfeizer/BioNTech vaccination.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multi-center study to identify biomarkers or marker combinations for early prediction of pregnancy complications in twin pregnancies in the first, second or third trimester.

In the future, the identified patients' risk will enable patients' referrals for proper prevention when such will become available

Specifically the investigators aim for

* Predicting the risk to develop preeclampsia, IUGR, preterm delivery, gestational Diabetes Melitus
* Assessment of major and minor markers for chromosomal and structural anomalies
* Identification of placenta accrete spectrum disorders and vasa previa
* Diagnosis of specific MC twin complications such as TTTS

The investigators will stratify and assess all the above according to chorionicity and delivery with complications at \<32 weeks, \<34 weeks, \<37 weeks, and at any gestation.

Screening methods will be conducted in the first, second or third trimester or at any gestation

Also the investigators aim to Identify the risk to lose one or both twins at \<32 weeks, \<34 weeks, \<37 weeks and at any gestation, the ability to predict fetal birth weight at \<32 weeks, \<34 weeks, \<37 weeks and at any gestation

The investigators also aim for monitoring any of the following maternal complications including placental abruption (clinically or on placental examination), postpartum hemorrhage (defined as blood loss ≥1 L within the first 24 hours after birth) at \<32 weeks, \<34 weeks, \<37 weeks and at any gestation.

The investigators will monitor

1. Neonatal morbidity due to intraventricular hemorrhage (IVH) grade II or above - Defined as bleeding into the ventricles, Grade II (moderate) - IVH occupies \<50% of the lateral ventricle volume, Grade III (severe) - IVH occupies ≥50% of the lateral ventricle volume or Grade IV (severe) - Hemorrhagic infarction in periventricular white matter ipsilateral to a large IVH
2. Neonatal sepsis confirmed bacteremia in cultures, anemia defined as low Hemoglobin and / or hematocrit requiring blood transfusion, respiratory distress syndrome defined as need for treatment by surfactant and ventilation, necrotizing enterocolitis requiring surgical intervention, and composite of any of the above
3. Newborn admission to neonatal intensive care units (NICU), length of stay and therapies during the admission.
4. Ventilation defined as a need for a positive pressure (continuous positive airway pressure (CPAP), nasal continuous positive airway pressure (NCPAP)) or intubation and a composite of any of the above
5. Any maternal complications within the first 6-10 weeks post delivery. The investigators will recruit patients in the different sites aiming for 1200 twin pregnancy and will collect the patients' entire pregnancy data for developing an algorithm to calculate the risk to develop the complications
6. Evaluation of serologic response to BNT162b2 Pfeizer/BioNTech vaccination.
