2 Thrombophilic Risk Factors in Preterm and Infants Treated at Ha'Emek Medical Center Between the Years 1990 to 2010

There are several factor that can be related to Neonatal Thrombotic events. Among them hypercoagulability can be the cause of those events. Factor V Leiden (FVL) and Prothrombin mutation are the most common causes of hereditary thrombophilia. The incidence of in the arab population is known to be higher than the incidence in another western populations. The purpose of this study is to review retrospectively the thrombophilic risk factors that were found in a cohort of premature babies and term newborns treated and investigated at the Neonatal Intensive Care Unit and at the Pediatric Hematology Unit.

5 Risk Factors for Variceal Bleeding in Egyptian Patients With Non-Cirrhotic Portal Hypertension

Background & Aims: Non-cirrhotic portal hypertension (NCPH) represents a relatively infrequent group of conditions. This work aimed at determining causes of NCPH and evaluating the role of some clinical, laboratory, imaging and endoscopic parameters in prediction of variceal bleeding in an Egyptian cohort with NCPH. Methods: Sixty patients with non-cirrhotic portal hypertension and oesophageal varices were included. All underwent complete clinical evaluation, laboratory investigations, Color Doppler ultrasonography, platelet count/spleen diameter (mm) ratio and upper gastrointestinal endoscopy. Patients were classified into two groups according to variceal bleeding: (1) Group I: twenty six patients with history of bleeding or had an attack of bleeding during one year follow-up; and (2) Group II: thirty four patients without bleeding.

NCT02635815 Portal Hypertension Procedure: Upper gastrointestinal endoscopy

Primary Outcomes

Measure: The presence or absence of variceal bleeding within one year of follow up.

The investigators excluded from the enrollment patients with severe thrombophilia: protein C, protein S, AT deficiency or homozygous FV Leiden and FIIG20210A mutations or double heterozygosity for FV Leiden and FIIG20120 mutations because in this patients the international guide lines suggest and recommend the use of antithrombotic prophylaxis

7 Downstream Molecular Signals of P2Y12 Receptors in Hyporeactive Patients Under Clopidogrel Treatment (A Possible Mechanism of HOTPR:High On- Treatment Platelet Reactivity)

The investigators designed the following experiment to observe the pattern of administration in vitro, which can be completely excluded liver enzyme cytochrome P450 metabolism under the influence and observe the relevant P2Y12 receptor downstream signal changes, hope in the above experiments, that the human body directly for the difference between the existence of drug reactions exist.

NCT03190005 Stable Angina Drug: clopidogrel Drug: Placebos
MeSH: Angina, Stable

The investigators ran a previous related plan within 2014 under the medical study project budget of the Taipei City hospital, which named "platelet reactivity as a post-percutaneous coronary stent implantation antiplatelet adjust the reference", it has been figured that responsibility under the P2Y12 receptor inhibitors were significantly different between the taiwanese and Caucasians (taiwanese revealed clopidogrel lower responsive, but stronger reaction to ticagrelor), although "low" response to clopidogrel between taiwanese (In fact, according to our experiments, 30 days after medication, the rate of HOTPR-High On- Treatment Platelet Reactivity; namely PRU≥208, the taiwanese and Caucasians are very close to each), but it has relative lower subacute stent thrombosis rate than the Caucasian at 30 days(This reaction is also known as the "Asian paradox" ), according to literature known abroad because of the high prevalence of CYP2C19 point gene deletion rate among the Asians (compare with Caucasians: ~ 65% vs ~ 30%); there also suggested other possible explanations: Caucasian factor V Leiden (G1691A) and prothrombin (G20210A) a higher proportion of mutations, on hemostatic factors (fibrinogen, d-dimer, and factor VIII) and plasma endothelial activation markers (such as von Willebrand factor, intercellular adhesion molecule 1, and E-selectin) existed differences between the races; in addition, a number of different indicators of inflammation, such as CRP. --- G1691A ---

8 The Role of Prothrombin Gene and Methylenetetrahydrofolate Reductase(MTHFR) Gene Polymorphisms as Risk Factors for Recurrent Miscarriage

Recurrent miscarriage is a pregnancy loss before 20 weeks of gestation. The recurrent pregnancy loss(RPL) usually occurring in the first trimester of gestation and its rate is quite high (15-20% even in full reproductive period) . In 2012, the American Society for Reproductive Medicine Practice Committee issued a statement that defined recurrent pregnancy loss as a disease distinct from infertility defined by two or more failed consecutive pregnancies.approximately 40% of couples will have an etiology identified that could be associated with their loss.

NCT03209063 Recurrent Miscarriage Diagnostic Test: polymerase chain reaction
MeSH: Abortion, Spontaneous Abortion, Habitual
HPO: Spontaneous abortion

40% of couples will have an etiology identified that could be associated with their loss.Thrombophilia is the tendency to develop thromboses due to inherited defects in the coagulation system.Thrombophilia was identified as a major cause of RPL,Because pregnancy is a hypercoagulable state, thromboembolism is the leading cause of antepartum and postpartum maternal mortality .The four most common genetic markers for thrombophilia are; prothrombin gene mutation(FII, G20210A), methylene tetra hydrofolate reductase mutations (MTHFR ,C677T and A1298C), factor V Leiden (FVL, G1691A) , and plasminogen activator inhibitor 1 (PAI-1) . --- G20210A --- --- C677T --- --- A1298C --- --- G1691A ---

Primary Outcomes

Description: using polymerase chain reaction Polymerase chain reaction

Measure: The study will compare the percentage of prothrombin gene and MTHFR gene polymorphisms in cases with recurrent miscarriage and healthy control group.
