The aim of this study is to determine whether three-dimensional tranesophageal echocardiography (3D TEE) assessment of ostium secundum atrial septal defect (ASD II) may be as efficient as two-dimensional (2D) TEE assessment complemented by the balloon-sizing during transcatheter closure of the defect.

Dialysis patients typically undergo 3 treatments a week every other day with an almost 3 day gap during the weekend. After this gap and before the first dialysis of the week the serum Potassium level is expected to be maximal. Participants will be recruited from the dialysis clinic at Hadassah Ein Kerem Hospital. The research team would personally meet the patients who answer inclusion criteria f and ask whether they wish to participate. Each willing participant will undergo Sialometry and blood will be drawn from the dialysis connections for CBC and Biochemistry to establish a baseline. The study measurements namely Sialometry and collection of Saliva as well as blood test will be taken before the initiation of the dialysis. Blood testing will be done via the laboratories of the Hadassah hospital. Saliva analysis will be done in the research lab of Prof. Doron Aframian.

The primary objective of this prospective, post-market study is to collect data to assess the long term outcome of a broad contact modular interbody device in the form of the InterFuse S™ or InterFuse T™ device in patients undergoing long construct fusion for degenerative disc disease and/or scoliosis. Comparisons will be made with published historical data..

The aim of this study is to determine the prevalence of psychological affection in infertile egyptian women

This study has two segments the first is a chart and outcome assessment of patients treated at Clear Passage (CP) with a history of small bowel obstruction (SBO). These patients have completed multiple questionnaires as a standard of care for outcome monitoring in the clinic setting, no new data will be collected. The second segment is a prospective observational, online questionnaire based study of subjects with a history of SBO not treated at CP. Data on the impact of quality of life (QOL) over time of subjects not treated at CP will be assessed using the same questionnaire used as standard of care in the clinic twice, 90 days apart. This will be accomplished using the NIH Assessment Center, with subjects able to complete the questionnaires with ease via the internet. As this segment is observational, there is minimal risk to these subjects. The data obtained from the untreated subjects will allow for reporting of overall impact on QOL in this population, data that is not available, as well as provide a control group for assessment of improvement for interventions for SBO.

Identifying patients who are at risk for a future myocardial infarction, is still one of the biggest challenges in cardiology. In this study the investigators will investigate culprit lesion in patients with NSTEMI and the ability of cardiac CT with dual energy computed tomography (DECT) scanning to describe and identify plaques that may be vulnerable. The investigators will also describe changes in characteristic in both stable and unstable plaques during 1 year follow up of NSTEMI and a matching group of stable angina pectoris (SAP) patients.

Primary Endpoint: The main objective of this National Registry is to identify the incidence and to analyse the risk factors for anastomotic leakage in rectal cancer surgery From the operational point of view, the aim of this Registry is to systematize the collection of information on the different surgical services. This Registry claims to have National audit functions, allowing thus the knowledge of the procedures performed at each center that could enable the establishment of the best standard of care. Secondary Endpoints: To determine the real incidence of anastomotic leakage according to the different locations and techniques: uniform definition of anastomotic leakage. To analyze the preoperative risk factors of anastomotic leakage: PATIENT FACTOR. To analyse the variability in the practice of rectal anastomosis: SURGEON FACTOR. To analyse the influence of different stapling devices in rectal anastomosis: INSTRUMENTAL FACTOR To know the current treatment of anastomotic leakage and the associated morbidity and mortality. To create and validate an anastomotic leakage predictive Score.

This study aimed to assess the correlation between the interleukin-10 (IL-10)-1082A/G polymorphism and idiopathic recurrent miscarriage (IRM) of Chinese Han. A total of 100 women with IRM and 100 control women with a successful pregnancy will be included in this study. Then genotyping will be performed.

Background and study aim The relative risks of duodenal adenocarcinoma and ampullary carcinoma in Familial Adenomatous Polyposis (FAP) have been estimated 100 to 330 times higher than in general population. However risk factors, including a genotype-phenotype association for duodenal cancer in FAP has not been fully understood. The aim of this study is to determine risk factors associated with the development of advanced duodenal polyposis and ampullary adenomas in colectomized patients with FAP.
