Suture Closure AFtEr VEIN Access for Cardiac Procedures (SAFE-VEIN) Trial
Atrial FibrillationAtrial Flutter6 morePrimary objective: To compare the safety and efficacy of closure strategies post venous access procedures. Hypothesis: We anticipate that the use of a venous closure device will decrease the time to hemostasis (TTH), time to ambulation (TTA) and time to discharge (TTD) compared to conventional methods of closure following venous access procedure.

Optimal Duration of Anticoagulation Therapy for Low-risk Pulmonary Embolism Patients With Cancer...
Venous ThrombosisNeoplasms1 moreThe primary purpose of this study is to determine the optimal duration of anticoagulation therapy (6 months versus 18 months) with direct oral anticoagulant (DOAC) for cancer-associated low-risk pulmonary embolism patients. The major secondary purpose of this study is to investigate whether home treatment of cancer-associated low-risk pulmonary embolism patients with rivaroxaban is feasible, effective, and safe through an observational management study.
TACE Combined With Iodine-125 Seeds Implantation for HCC
Hepatocellular CarcinomaPortal Vein Occlusion1 morePortal vein tumour thrombus (PVTT) is a common complication of hepatocellular carcinoma (HCC). PVTT has a profound adverse effect on prognosis, with a very short median survival time (2-4 months). The presence of PVTT also limits treatment options, such as liver transplantation and curative resection. Although the Barcelona Clinic Liver Cancer group recommended sorafenib as a standard therapy for advanced-stage HCC, the optimal treatment for HCC with PVTT remains largely controversial. Some studies have reported a survival benefit in patients with PVTT who underwent transarterial chemoembolization (TACE), even in patients with main portal vein (MPV) tumor thrombus. Iodine-125 brachytherapy had also showed promising efficacy as a new method for unresectable HCC with PVTT. Results of our previous study indicated that TACE combined with Iodine-125 seeds implantation might be a good choice for selected patients with PVTT. Thus, we conduct this study to farther evaluate the effect of TACE combined with Iodine-125 seeds implantation for HCC with PVTT. 270 patients with HCC and PVTT will be included and randomized to two group: group 1, patients received TACE combined with Iodine-125 seeds implantation; group 2, patients received TACE alone. TACE and Iodine-125 seeds implantation will be performed with a standardized procedure. Iodine-125 seeds implantation into PVTT (guided by CT) will be conducted 7 days after TACE. All patients revisit our institutions for follow-up examinations including contrast enhanced CT/MRI and laboratory tests every 4-6 weeks after the first treatment. Patients who have a tumor response rating of complete response will be required to revisit 3 months interval. At each visit, TACE or Iodine-125 seeds implantation is repeated if the following criteria are reached: 1) images indicating viable intrahepatic tumor tissue or PVTT; 2) Child-Pugh class A or B, and no contraindication to TACE and Iodine-125 seeds implantation. The primary end point of this study is overall survival. The secondary end points are time to tumor progression, disease control rate, duration of portal patency and adverse events. All adverse events are graded in accordance with Common Toxicity Criteria Adverse Events Version (CTCAE) 4.03.
Sinus Floor Augmentation and Graft Compared Sinus Membrane Elevation With Blood Coagulum. A Randomized...
Dental Implant FailedImplant placement in posterior maxilla is often compromised or impossible due to atrophy of the bone and pneumatisation of the maxillary sinus. Thus, alveolar ridge augmentation is frequently necessary. The most commonly used method to augment the maxillary region involves the maxillary sinus floor augmentation (MSFA) with autogenous bone graft or bone substitute. Harvesting of autogenous bone graft is associated with risk of donor site morbidity and unpredictable resorption of the graft. Thus, bone substitutes alone or in combination with autogenous bone are used increasingly. Symbios xenograft granules is a new porcine bone mineral. Long-term studies have demonstrated that xenograft contains osteoconductive properties and is a safe grafting material. MSFA with xenograft alone or in combination with autogenous bone have shown high implant survival with new bone formation. In contrast, the maxillary sinus cavities possess significant potential for bone regeneration without the use of additional bone grafts or bone substitutes due to the principle of periosteal guided bone regeneration and surrounding bony walls. Bone regeneration after maxillary sinus membrane elevation with the use of coagulum as grafting material has shown high implant survival with new bone formation, as documented in reviews and short-term studies. The objective is to test the H0-hypothesis of no difference in the long-term implant outcome after MSFA with 1:1 mixture of autogenous bone graft and Symbios xenograft (control) compared with the coagulum (test). Forty consecutively healthy patients with a missing posterior maxillary tooth will be allocated to test or control. Implants will be inserted simultaneously with the MSFA. Clinical and/or radiographical evaluation using periapical radiographs and Cone Beam Computer Tomography (CBCT) will be performed preoperatively, immediate postoperatively, before abutment connection, after prosthetic rehabilitation, and one year after loading to assess the implant treatment outcome and the volumetric changes of the augmented area. The primary outcome will include survival of suprastructures, survival of implants, volumetric stability of the augmented area, peri-implant marginal bone level, oral health related quality of life, and complications related to the two treatment modalities.
API-CAT STUDY for APIxaban Cancer Associated Thrombosis
Cancer-associated ThrombosisThe main objective is to determine whether a low-dose regimen of apixaban (2.5 mg bid) is non inferior to a full-dose regimen of apixaban (5 mg bid) for the prevention of recurrent venous thromboembolism (VTE) in patients with active cancer who have completed at least 6 months of anticoagulant therapy for treating a documented index event of proximal deep venous thrombosis (DVT) (symptomatic or incidental) or pulmonary embolism (symptomatic or incidental).
