A Study Evaluating the Safety and Efficacy of Transplantation of a single cord blood unit (CBU) of NiCord®, umbilical cord blood-derived Ex Vivo Expanded Stem and Progenitor Cells in Patients with Hematological Malignancies.
This randomized, double-blind, regimen-controlled, phase II, multicenter study will assess the efficacy and safety of two different vismodegib regimens in participants with multiple basal cell carcinoma. Participants will receive vismodegib 150 mg orally once daily either in an intermittent schedule of 12 weeks vismodegib followed by 8 weeks placebo (Arm A) or as 24 weeks induction followed by an intermittent schedule of 8 weeks placebo followed by 8 weeks vismodegib (Arm B). Anticipated time on study treatment is 72 weeks.
The primary objective of this study is to evaluate the non-inferiority of switching to a tenofovir alafenamide (TAF)-containing fixed dose combination (FDC) relative to maintaining tenofovir disoproxil fumarate (TDF)-containing combination regimens in virologically suppressed HIV-infected participants as determined by having HIV-1 RNA < 50 copies/mL at Week 48.
Acute allograft dysfunction is often observed in the first weeks after kidney transplantation. Renal biopsy is universally considered the gold standard procedure for differential diagnosis of acute allograft dysfunction secondary to intraparenchymal causes. Kidney biopsy, however, is an invasive procedure that is time and cost consuming. Moreover, it may but not contribute to clinical diagnosis in about 10% of cases because of the impossibility to perform the analysis or of inadequacy of the biopsy sample. Availability or readily applicable non-invasive procedures might therefore allow increasing the performance of differential diagnosis of allograft dysfunction. In the recent years, a novel US imaging technique, namely contrast-enhanced ultrasound (CE-US),has been developed. The agent used in this study, Sonovue microbubbles consist of a central sulphur hexafluoride core with a surrounding phospholipid monolayer and last for several minutes in the systemic circulation before spontaneous degradation with absorption of the gaseous component by the lungs and the phospholipid shell by the liver. With the use of gasfilled microbubbles that act as scatterers within the blood stream and the development of low-MI ultrasound techniques that allow the visualization of the bubbles without destroying them, it is possible to improve the depiction of vessels and have access to structural and functional information on the microcirculation. Moreover SonoVue microbubbles are not nephrotoxic and can be safely used to evaluate kidney disfunction. Thus, whether a. different patterns of parenchymal perfusion detected by CE-US can be associated with different patterns of renal graft involvement during acute renal function deterioration and b. whether, conversely, different patterns of parenchymal perfusion detected by CE-US may help predicting different patterns of renal involvement will be investigated in 20 deceased or living donor kidney graft recipients.
Arthroscopic transosseous fixation of rotator cuff tears has become an alternative to arthroscopic suture anchor. This novel technique that allows surgeons to perform a standardized arthroscopic transosseous (anchor free) repair of rotator cuff tears can improve postoperative pain and reduce the incidence of shoulder stiffness. The aim of the this study is to compare clinical outcomes of two groups of patients: patients that received an arthroscopic transosseous fixation using the ArthroTunneler tunneling device (Tornier Inc, Edina, Minnesota) versus patients that received an arthroscopic rotator cuff repair using suture anchors.
The experimental treatment consists in the application of a therapeutic strategy of allogeneic transplantation as a potential curative procedure in a population of patients with chemoresistant acute leukemias. Therapeutic intervention, namely the conditioning regimen as well as GVHD prophylaxis, are based on regimens currently in standard use in the context of allogeneic transplantation.
This study will be performed as a prospective multicenter phase II trial for compare busulfan-fludarabine reduced-intensity conditioning (RIC) with thiotepa-fludarabine RIC regimen prior to allogeneic transplantation of hematopoietic cells for the treatment of myelofibrosis. The primary endpoint for this study is to compare Progression Free Survival of two different RIC regimens for allogeneic stem cell transplantation in myelofibrosis. Progression Free Survival is defined as the time from the date of randomization to the date of the first documented disease progression or relapse (according to the International Working Group Consensus Criteria) or death due to any cause. Patients who have neither progressed nor died at the time of study completion or who are lost to follow-up are censored at the data of the last follow up for progression of disease for this study.
Cardioinhibitory neurocardiogenic syncope (CNS) or vasovagal syncope, is the most frequent aetiology of syncope in young people without apparent cardiac or neurological pathology. It is usually caused by inappropriately trigger-activated cardiac reflex which finally precipitates asystole, sinus bradycardia, or atrioventricular (AV) block [1]. Despite young patients affected by CNS have an excellent prognosis when electro-structural heart diseases are excluded [2], their quality of life may be seriously affected by recurrent episodes [2, 3]. Cardiac pacing might help to control symptoms and therefore is considered in patients aged more than 40 years old with recurrent episodes and documented cardioinhibitory response [1, 4]. In young individuals, the role of cardiac pacing is dubious due to predicted frequent device substitutions and adverse ventricular remodeling over time. Recently, radiofrequency (RF) biatrial ablation of ganglionated plexi (GP) has showed promising results in the short and long-term treatment of reflex syncope, functional atrioventricular block, or sinus node dysfunction [5, 6]. Nonetheless, strong evidences are emerging about efficacy of transcatheter ablation limited to ganglionated plexi in the right atrium with the possibility to avoid side-effects related to left-sided procedures [6] Aim of study To evaluate in a large cohort of patients effectiveness and safety of gangliar transcatheter ablation in the right atrium to obtain atrial denervation and prevent CNS. Study population and methods Twenty consecutive patients affected by cardioinhibitory neurocardiogenic syncope will be enrolled in the study. Inclusion criteria: - age between 18 and 60 years - 3 syncopal episodes at least of likely CNS in the previous 2 years - marked cardioinhibitory response to HUT or documented asystolic pauses at internal loop recorder registration [7]. Cardioinhibition will be considered as elicitation of asystolic pause (sinus arrest or AV block) ≥ 3 seconds associated to syncope or ≥ 6 seconds and related presyncope. Exclusion criteria: - documented myocardial and/or valvular abnormalities on 2D echocardiogram (ejection fraction lower than 50%) - documented tachyarrhythmias as possible causes of symptoms - channelopathies (Brugada syndrome, LQT or SQT syndrome) - ventricular preexcitation - symptomatic orthostatic hypotension diagnosed by standing blood pressure measurement - pregnancy in women - previous cardiac pacemaker implantation. After obtaining informed consent patients will undergo to basal electrophysiological study (EPS) to record AH interval, HV interval, Wenckebach cycle length, sinus node recovery time (SNRT) and correct sinus node recovery time (cSNRT); the same parameters will be recorded immediately after ablation. Following basal EPS an accurate (200 valid points at least) electroanatomic right atrium mapping (CARTO 3™ Biosense Webster, Inc) will be performed and subsequently radiofrequency delivered at right atrial anatomic sites where the underlying presence of ganglionated plexi (GPs) clusters was regarded as highly probable, on the basis of anatomical studies [8-11]: the supero-posterior area (superior right atrial GP, adjacent to the junction of the superior vena cava and the posterior surface of RA), the middleposterior area (posterior right atrial GP, posterior surface of the RA adjacent the interatrial groove), the infero-posterior area (inferior right GP placed between the inferior vena cava, coronary sinus ostium, and near the atrioventricular groove). Transcatheter ablation will be performed using an 8mm-tip catheter (Biosence-Webster Navistar DS 8mm) or an irrigated 4 mm-tip catheter with force control system (Biosence Webster Smarttouch). Ablation will be performed until complete elimination of local atrial electrical activity. Response to radiofrequencies delivery will be considered successful in case of asystolic pause or cardiac cycle lengthening of 30% (compared to basal cycle) at least. To prolong RF delivery despite asystolic response, a quadripolar catheter will be positioned in right ventricle to backup stimulation. To avoid phrenic nerve injury, high amplitude stimulation will be performed just before radiofrequency delivery to the superior right atrial GP. HRV analysis will be performed on admission, at 2 hour after ablation and patients discharge. The HRV analysis will include the following parameters: mean, maximal and minimal heart rate, SDNN (standard deviation of Normal-Normal), RMSSD (root mean square successive difference), pNN50 (percentage of differences between adjacent N-N intervals that are >50 msec), LF (low frequency), HF (high frequency). Moreover, an HUT and an HRV analysis will be performed at 1, 3, 6 and 12 months after ablation procedure during the follow up.
This is a prospective observational study investigating how physicians assess the risk of febrile neutropenia (FN) developing in patients who will receive chemotherapy. Approximately 150-200 investigators will take part in about 100 sites in Europe, Canada and Australia. Approximately 1000 subjects will be studied, all of whom will have non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC), non-Hodgkin's lymphoma (NHL) or breast cancer and will be due to receive one of the specific chemotherapy regimens of interest. Investigators' approach to FN risk assessment will be studied using lists of possible risk factors they may consider during their assessment. Investigators will be asked to select and rank the factors they consider the most important when assessing the overall FN risk of a subject and when making the decision whether to treat with granulocyte-colony stimulating factor (G-CSF) primary prophylaxis (PP). They will be asked to make these selections based initially on their own routine clinical practise and subsequently relating specifically to each subject recruited. This is a non-interventional study that involves no procedures outside normal care for the subjects; all data collection will be completed prior to chemotherapy administration.
After a stent procedure, it is common practice to prescribe anti-platelet medication to prevent the blood from clotting. The main objective of this study is to determine if there is a better medication strategy to prevent blood from clotting and at the same time minimising the number of complications. There are two medication strategies: - Study group: Dual anti-platelet therapy (ticagrelor combined with aspirin) for 1 month, and then ticagrelor alone for another 23 months OR - Control group: Standard treatment, being dual anti-platelet therapy (ticagrelor or clopidogrel combined with aspirin) for 12 months, and then aspirin alone indefinitely
