NCT ID: NCT02257931 Completed - Clinical trials for Allogeneic or Autologous HSCT

Gram-negative Bacteremia in HSCT Recipients

GNB
Start date: February 2014
Phase: N/A
Study type: Observational [Patient Registry]

A significant increase in resistant bacteria emerging in HSCT recipients. For example, 25% - 42% of all enterobacteriaceae produce extended spectrum beta-lactamases; 8 - 72% of Pseudomonas aeruginosa are resistant to at least one and 25 - 62% to three or more antibiotic classes, 13% of Gram-negative bacteria are caused by a multidrug-resistant (MDR) strain (Trecarichi JI 09, Mikulska BBMT 09, Oliveira BMT 07, Caselli Haemat 10, Gudiol, JAC 11). These resistant bacteria may be associated with increased mortality and have limited treatment options (Caselli Haemat 10, Poutsiaka BMT 07, DiazGranadoz JID 05). To provide the currently best empirical coverage and to control the growing resistance, knowledge of trends in antibiotic susceptibility, as well as risk factors is essential. For this reason we propose to perform non-interventional prospective multicentre study in EBMT centres.

NCT ID: NCT02256241 Recruiting - Clinical trials for Group 2: Primary Tumors of Mesenchymal Origin

The Role of RING Ubiquitin Ligases in Biologic and Oncologic Processes in Tissues of Mesenchymal Origin

RING UB LIGASE
Start date: October 2014
Phase: N/A
Study type: Observational

Stage 1: Bone marrow will be collected from otherwise healthy patients undergoing orthopedic surgery - arthroplasty for the treatment of degenerative joint disease or traumatised patients. The bone marrow will be collected from disposable tissue that is removed during the normal sequence of the surgery. These cells will be used for: Establishment of the role of RING ubiquitin ligases in osteogenic progenitors proliferation and differentiation in culture. I. To determine the levels of RING ubiquitin ligases mRNA and protein in differentiating human mesenchymal precursor cells: To test the correlation between levels of RING ubiquitin ligases and degree of osteogenic differentiation, we will extract mesenchymal precursor cells from the collected tissue and test the mRNA protein level of RING ubiquitin ligases upon induction of differentiation. Specifically, we will compare the levels of RING ubiquitin ligases before and after the initiation of differentiational stimulus in time dependent manner by western blot and real time PCR analysis. II. To test the impact of specific RING ubiquitin ligases on differentiation of human mesenchymal precursor cells: to test the impact of RING ubiquitin ligases on the differentiation of mesenchymal precursor cell from the collected tissue by testing the expression of classical differentiational bone markers by flow cytometry (fibronectin, CD105) and by Alkaline phosphatase (ALP) activity assay. For this aim we developed both a constitutive and Dox-regulated conditional overexpression and shRNA lenti-viral systems that enables efficient modulation of these RING ubiquitin ligases level. III. Determine the role of RING ubiquitin ligases in proliferation and survival of human mesenchymal precursor cells: Via inhibition or overexpression of ligases in mesenchymal progenitor cells we will test the role of these ligases in proliferation and survival of mesenchymal precursors by using MTT assay, Propidion-Iodid (PI) and tunnel assays in flow cytometry analysis. Stage 2: Collection of connective tissue from patients with malignancies of musculoskeletal origin. The tissue that will be used is part of the resected tumor specimens. The tissue will be used for: The establishment of the role/s of RING ligases in musculoskeletal cancers using cell culture and in vivo activation. Test if the expression of selected positive candidates from stage 1 correlates with cancer development and progression in human-derived samples Independently of our mechanistic experiment we aim to determine the relevance of these ligases to human musculoskeletal cancers. As the first step we will screen primary tumor biopsies at the protein level correlates with cancer grade and prognosis. Toward this aim we recently generated a highly specific several anti-monoclonal antibodies in our laboratory as well use comercial available antibodies .

NCT ID: NCT02255578 Not yet recruiting - Clinical trials for Polycystic Ovary Syndrome

Endobarrier Treatment in Women With PCOS

EPCOS
Start date: September 2014
Phase: Phase 3
Study type: Interventional

Women with Polycystic ovary syndrome (PCOS) experience multiple fertility treatments, a long treatment duration and a low pregnancy prevalence. This syndrome is frequently accompanied by overweight and insulin resistance which can mediate the limited response to fertility treatment. The Endobarrier device was shown to be efficient in weight and glucose lowering. The aim of this study is to investigate the ability of the Endobarrier device to improve the outcome of fertility treatments in women with PCOS.

NCT ID: NCT02253758 Not yet recruiting - Anesthesia Clinical Trials

Arousal Pathways and Emergence From Sedation

Start date: October 2014
Phase: N/A
Study type: Interventional

Emergence from sedation involves an increase in both the level of consciousness and arousal. Some insight to the neural core of consciousness was gained in the recent past. Our research objective is to characterize for the first time the spatiotemporal mobilization of the ascending reticular activating system during emergence from sedation; stated otherwise - to capture the neural core of arousal. To achieve this objective we plan to utilize the advanced imaging modality of EEG-fMRI. In short, volunteers will be placed in the MRI. Following baseline recordings they will be sedated with a continuous drip of propofol, titrated to deep sedation. Once in that sedation level, propofol administration will cease until emerging to an awake-calm/light sedation. Continuous EEG recordings and fMRI scans will be taken, both task specific (auditory oddball) and resting-fMRI. Analyses will focus (but will not be restricted to) on constituents of the ascending reticular activating system. The expected advances of this proposal are: 1. Emergence from sedation (and anesthesia) is one of the critical stages and least elucidated area in the practice of anesthesia. Delayed awakening of varying degree is not uncommon after anesthesia and may have a number of different causes, individual or combined, which may be both drug or non-drug related, thus causing a diagnostic dilemma. Eventually - better insight into this subject will lead to better clinical practice and better understanding why patients emerge in such a diverse and sometimes unexpected manner. 2. Knowledge of the internal structure underlying arousal from anesthesia will help develop / upgrade brain monitors that could tell the anesthesiologist the patient's level of consciousness and prediction of arousal. 3. A detailed reproducible mapping of the arousal process may serve as the core of a drug screening platform for drugs that may expedite patient arousal. 4. Elucidation of the arousal paradigm from sedation will enhance our knowledge of physiological sleep. Research hypothesis Return of consciousness is a complex phenomenon comprising of interplay between the cortex and deeper brain structures. We hypothesize that the activation signature is conserved and similar between subjects. Furthermore, we hypothesize that inter-subject variability will arise mainly in the time domain, as evident from the clinical observation of variable time to emergence in different patients.

NCT ID: NCT02253706 Not yet recruiting - Hypoxia Clinical Trials

Oxygen Supplementation During Bronchoscopy: High Flow Versus Low Flow Oxygen

Start date: October 2014
Phase: N/A
Study type: Interventional

In general bronchoscopy is a safe procedure with low rate of complications. Indeed, contraindications to flexible bronchoscopy are mostly relative rather than absolute. This is the case of preexisting decreased blood oxygen levels which may be present in patients requiring further bronchopulmonary investigation. To avoid the deleterious effects of oxygen drops oxygen supplementation is recommended. The purpose of this study is to evaluate the efficiency and safety of oxygen supplementation obtained with the use of a high flow nasal cannula compared with a low flow nasal cannula during flexible bronchoscopy. Consecutive patients referred by their treating physician for bronchoscopy will be offered to take part in the study. Those who wish to participate and give their consent will be randomly assigned into one of two treatment groups (supplemental oxygen given via low flow nasal cannula or via high flow nasal cannula). Assignment to either treatment arm will not affect in any way the intended purpose of the bronchoscopy. All patients will be closely monitored during the procedure and 2 hours following its completion. Monitoring will be conducted, using strictly non-invasive measures.
