Filter by:This is a multi-center, observational cohort study including patients with prior coronary artery bypass grafting (CABG) and ≥1 saphenous vein grafts (SVG) presenting with recurrent ischemic symptoms. Objective: to investigate the clinical outcomes in patients with prior CABG evaluated for bypass graft failure and progression of native coronary artery disease (CAD). Follow-up will be collected through national registry databases, electronic medical patient records and standardized telephonic assessment at 3 and 5 years follow-up.
Removal of meniscal tissue is described to result in poor knee function and a significant risk for future development of osteoarthritis. Different implants have been suggested to substitute a removed meniscus. Meniscal allograft transplantation is not widely available due to costs and availability. The semitendinosus tendon is a known graft with biological properties with potential to remodel and revascularize in an intraarticular environment such as anterior cruciate ligament reconstruction. The objective for this study was to investigate whether the semitendinosus tendon graft could function as a meniscal transplant.
This study is designed as an open-label, single arm, proof of concept study in order to determine the appropriate emapalumab dosing regimen neutralizing IFNγ in patients at risk of GF. Patients presenting CXCL9 levels above a defined threshold and other clinical criteria will be eligible to receive emapalumab. Both children and adults, with malignant and non-malignant underlying diseases, receiving allo-HSCT who are at high risk of GF as defined in the inclusion criteria will be included in the study. The main objective of the study is to determine the appropriate emapalumab dose regimen neutralizing interferon gamma (IFNγ) activity to pre-empt graft failure post allo-HSCT in a population with various underlying diseases and at high risk of graft failure (GF). Maximum 3 cohorts are foreseen to determine the appropriate dose regimen to pre-emptively treat patients at risk of primary GF. Emapalumab will be administered by IV infusion and treatment will last up to 56 days (15 infusions) or until evidence of engraftment. The study is expected to last approximately 3 years from screening to the last follow-up phone call for each patient.
This is a prospective, observational cohort study, designed to explore the use of NIRS in kidney transplants. This study will investigate an association between measurements of intra- operative NIRS and post - operative graft dysfunction as manifested in initiation of renal replacement therapy.
Methods: Out of 2000 kidney transplant recipients in our center in Kuwait, collecting data was started for all COVID-19-positive kidney transplant recipients till August 2020. Clinical features, management details and both patient and graft outcomes were reported.
Clinical study designed to collect blood for research purposes in patients after hematopoietic stem cell transplantation (HSCT) or in patients with a medical condition where the blood cells production is impaired. The blood samples will be used to study the role of Interferon gamma (IFNɣ) in graft failure or impairment of hematopoietic stem cell proliferation. The IFNɣ signature will be assessed by measuring primarily IFNɣ and C-X-C Motif Chemokine Ligand 9 (CXCL9).
Poor graft function (PGF) after allogeneic hematopoietic cell transplantation (allo-HCT) is a misunderstood complication associated with poor outcome and limited therapeutic options. Despite the lack of standardized diagnostic criteria, PGF is commonly defined as follows: one or several significant cytopenias after allo-HCT persisting or developing after allo-HCT despite full donor chimerism and in the absence of relapse or other causes. Not only PGF can alter patients' quality of life by leading to recurrent transfusions, bleeding events and infections, but it is also associated with poor survival after allo-HCT. Although PGF is relatively frequent, there is no well-codified behavior in the literature or in the recommendations issued by the various learned societies of transplantation. The aim objective of the investigator's study is to demonstrate that eltrombopag improve PGF after allo-HCT
This study aims to investigate the clinical effect of the new saphenous vein harvesting technique "No-touch" in off-pump coronary artery bypass grafting(OPCABG), comparing to the conventional technique. Adopting CTA to evaluate the 3 months patency of the graft, we will compare veins harvested using No-touch technique to saphenous veins using conventional open technique.
Graft failure is a lethal complication after allogeneic stem cell transplantation, which often need a salvage transplantation. However, the current outcome of second transplantation for graft failure is far from satisfactory. We performed a prospective single-arm study to investigate the safety and efficacy of a novel regimen.
An irreparable rotator cuff tear (IRCT) is a challenge, with a controversial definition and different treatment options. None of the latter are exempt of limitations and their survivorship is one of the concerns. In 2013, Mihata et al. proposed a novel treatment option: arthroscopic superior capsular reconstruction using a fascia lata autograft (FL-ASCR) harvested through an open approach. Although no harvest site dysfunction was reported, concerns about donor site morbidity discouraged the use of this type of graft. In 2015, the investigators modified the original FL-ASCR introducing a minimally invasive fascia lata harvesting technique, aiming to reproduce FL-ASCR's promising clinical results in IRCT, while reducing donor site morbidity. The investigators aim to: 1) Evaluate the mid-term outcomes and donor site morbidity impact of FL-ASCR with minimally invasive harvesting; 2) Analyze the mid-term graft integrity to determine its survivorship 3) Establish clinical and imaging graft integrity correlations to guide the future treatment algorithm.
