NCT ID: NCT05014763 Not yet recruiting - Clinical trials for Alveolar Ridge Augmentation

Peri-implant Tissue Stability Following Tissue Augmentation Harvested From Deep Palate or Tuberosity

Start date: September 20, 2021
Phase: N/A
Study type: Interventional

This study will compare peri implant tissue stability following connective tissue graft harvested fromLateral Palate or the Tuberosity Area. As far as we know, it remains controversial whether peri-implant soft tissue stability could be achieved after soft tissue augmentation with the connective tissue graft from the tuberosity or the lateral palate. Soft tissue stability evaluated by intra oral scanner will be described as primary outcome.

NCT ID: NCT03386435 Completed - Clinical trials for Liver Transplantation

The Effect of Remote Ischemic Preconditioning in Living Donor Hepatectomy

Start date: August 22, 2016
Phase: N/A
Study type: Interventional

Liver transplantation is the gold standard treatment for patients with end-stage liver disease. Despite its outstanding success, liver transplantation still entails certain complications including ischemia-reperfusion injury. Remote ischemic preconditioning is a novel and simple therapeutic method to lessen the harmful effects of ischemia-reperfusion injury, however, the majority of remote ischemic preconditioning studies on hepatic ischemia-reperfusion injury have been animal studies. Therefore, our aim was to assess the effects of remote ischemic preconditioning on postoperative liver function in living donor hepatectomy.

NCT ID: NCT03000244 Recruiting - Clinical trials for Hematopoietic Stem Cell Transplantation

Long-Term Follow-up of People Undergoing Hematopoietic Stem Cell Transplantation

Start date: April 26, 2017
Phase:
Study type: Observational

Background: People who have had an allogeneic hematopoietic stem cell transplant (HCT) have bone marrow or an immune system that is damaged. They get stem cells from a donor who is a relative. Researchers want to study stem cell donors and recipients to learn about the long-term effects of HCT. They want to learn how the stem cells change and how to improve their ability to fight cancer. Objective: To provide long-term follow-up care for people who underwent or will undergo HCT. To collect data, blood, and tissue samples to learn about late complications after HCT. Eligibility: Adults age 18 and older who will undergo HCT or underwent HCT and are surviving one year or more from the date of HCT. The stem cell donors for these recipients are also needed. Design: Recipients will have 1 visit each year. They will have a physical exam. They will answer questions about their medical history and health. They will receive screening and surveillance testing. They will complete brief questionnaires. Recipients will have blood tests. They may have tissue biopsies or specimens (such as tissue in their cheek or skin or bone marrow biopsy). Recipients will give their current address and phone number, and the same data for one or two other people, who can get in contact with them. After the first visit at the clinic, some recipients may see a doctor close to home to get the necessary information and send it to NIH. Donors will come to the clinic for 1 visit. They will answer questions about their medical history. Blood samples will be taken....

NCT ID: NCT01742234 Completed - Living Donors Clinical Trials

RELIVE Informed Consent Study

Start date: August 2008
Phase: N/A
Study type: Observational

An organ transplant is frequently the best option and, in some cases, the only option to save the lives of transplant recipients. Receiving an organ from a living donor eliminates the need to wait for a deceased donor, an option that many transplant recipients do not survive. However, donating an organ presents health concerns to the donor as well. This study will use surveys to evaluate the understanding of risk and psychological pressure that living organ donors felt when making the decision to donate. It will also compare participants' answers across geographic, racial and socio-economic backgrounds.

NCT ID: NCT01214018 Terminated - Clinical trials for Stress Disorders, Post-Traumatic

Evaluation of Post-traumatic Stress Among the Nearest Relatives of Brain-dead Organ Donors

Start date: May 15, 2011
Phase: N/A
Study type: Observational

The goal is to compare post tramautic stress between the nearest relatives of brain-dead patients who are organ donor to those of brain-dead patients who are not organ donors for medical, legal or opposition reasons.
