Filter by:China patients in end stage renal disease receiving maintenance dialysis have a high risk of cardiovascular disease (CVD), with a prevalence of 45.5% approximately, and coronary artery disease (CAD) has been identified as the most common one. It remains unclear that what their treatment status is and whether this group of patients can benefit from revascularization in China. The investigators plan to recruit around 30 hospitals from 7 regions as study centers, which represent different levels of economic development in Mainland China. The detailed information includes demographics, medical history, coronary angiogram, in-hospital treatment and procedures, short-term and long-term outcomes. The aim of the study is to provide the real world knowledge about current status of coronary revascularization and prognosis in patients with CAD and dialysis.
The purpose of this research is to test a service the investigators of the study believe may increase quality of life after brain injury and reduce the level of disability that might be associated with that injury. This intervention is called "Resource Facilitation" and involves working one on one with a brain injury specialist. This specialist is called a "Resource Facilitator" and will work with participants to help set and achieve their own goals along with a team of professionals that specialize in this kind of injury. If randomly assigned to the Resource Facilitation group, participants will receive Resource Facilitation free of charge. If not, they will be assigned to a control group and will not receive the intervention. However, both groups will receive calls every three months. During these calls, a research assistant will collect data about each participant's recovery and progress. If assigned to the Resource Facilitation group, participants may also receive study information in the mail if research assistants are unable to reach participants via telephone.
Nowadays, endoscopic techniques have been applied for diagnosing and treating a variety of gastrointestinal diseases, such as endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR)technique for removing early gastrointestinal mucosal cancers. Endoscopic procedure associated gastrointestinal perforation is one of the the most severe complications, which is associated with high morality and needs timely detection and effective treatment in clinical practice.Over 90% procedure associated gastrointestinal perforation occurs immediately within 24 h after endoscopic procedure.Endoclips have been widely used in closing the immediate gastrointestinal perforations, but the location of the endoclips could influence the effective rate, limiting its application. In addition, multiple endoclips should be placed under endoscopy for a relatively large perforation, which could increase the medical cost and the procedure time. At recent, a new purse string suture device (LeoMed, China) has been developed by us and introduced to the clinicalmanagement of such patients with procedure associated gastrointestinal perforations. Clinical data validated that the usage of this new purse string suture in treating immediate procedure associated perforations was greatly convenient and effective with very low reoperation rate and postoperative complication rate. A specially designed loop was equipped in this device, which could be tightened under endoscopy. Thus, compared with the placement of endoclips, this device could be more convenient and effective in completely closing the gastrointestinal perforations.This study will test whether purse string suture device will increase the effectiveness of closingimmediate procedure associated gastrointestinal perforationsunder endoscopyin a randomized controlled trialby comparing the use of purse string suture deviceand endoclips.
The transradial approach for coronary angiography and angioplasty is now widely used in catheterization laboratories worldwide, which had been shown as advantages over the conventional femoral and brachial approaches due to the lower incidence of bleeding and other cardiovascular complications. However, the transradial approach does not seem suitable for 5-15% of patients undergoing coronary angiography and angioplasty. The ulnar artery which is one of the two terminal branches of the brachial artery is usually larger than radial artery and it may be as a potential approach for cardiac catheterization. Recently, some reports have demonstrated that the transulnar approach may be both feasible and safe for coronary angiography and angioplasty in selective patients.we performed this study to evaluate the safety and feasibility of transulnar approach coronary catheterization in real world non-selective patients.
This study is an investigator-initiated study. The study will be performed as a prospective, randomized, controlled multi-center trial to evaluate the safety and efficiency of Xpert stents compared to PTA in patients with chronic distal artery occlusions or stenosis undergoing catheter revascularization. Patients will be eligible for randomization if they are over 18 years old, if they undergo percutaneous catheter revascularization of an artery below the knee stenosis/occlusion that is less than 15 centimeters in length. Up to two vessels may be treated in this study. All lesions greater than 50% in the below the knee artery region have to be treated either with PTA or stenting according to the randomization.
