Filter by:The purpose of this study is to assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and preliminary antitumor activity of AZD4573 in subjects with relapsed or refractory haematological malignancies.
The aim is to evaluate the peak secretory flow rates and bicarbonate concentrations as determined by a 30 minute intraductal secretin stimulation test in patients with a low likelihood of pancreatic pathology and to compare these data to those obtained from our historical patients with suspected chronic pancreatitis. These will be patients in which inadvertent pancreatic cannulation occurs during therapeutic endoscopic retrograde cholangiopancreatography (ERCP) for biliary indications . All study subjects will receive a 5 day follow-up phone call. Enrollment goal is 36 subjects.
Purpose: To conduct a randomized controlled pilot study investigating the use of high dose intravenous (IV) thiamine to prevent delirium and mitigate the long-term effects of delirium, including health-related quality of life (HRQOL), functional status, and neuropsychiatric outcomes, in patients admitted to University of North Carolina (UNC) Hospital for allogeneic hematopoietic stem cell transplant (HSCT). Participants: 60 adult inpatients admitted to the UNC Bone Marrow Transplant Unit for allogeneic stem cell transplant. Procedures (methods): Participants will be admitted for allogeneic HSCT and on the day after transplant randomized to seven days of high dose IV thiamine or placebo. Thiamine levels will be measured weekly and participants will be assessed for evidence of delirium using validated measures. Validated measures will also be used to assess cognitive function, depression, post-traumatic stress symptoms, functional status, and HRQOL prior to hospitalization and at one, three, and six months after transplant.
Europe is undergoing a demographic change with a rapidly growing population of 65 years+. This challenges municipalities and hospitals as the ageing citizens need care and treatment due to an age-related decline in physical and mental capacity. Therefore municipalities are experiencing a growing need for sufficient and customized housing, which can support the elderly citizens in sustaining well-being and health along with preventing functional decline. Well-fare technologies, such as Circadian adjusted LED-based lighting (CALED), are suggested as a remedy for this. To obtain proper visual sharpness and better contrast, people of older age require heightened light levels due to age-related failing vision. Furthermore, inappropriate light at night disrupts not only sleep but also the timing of the circadian rhythm, with negative consequences on cognition and emotions. Therefore CALED is being increasingly considered for use in hospitals and elderly housing because of its wide spectrum of wavelengths, good contrast and fast switching, and possibility to support a normalised circadian rhythm. Lighting based on LED has been shown to improve the quality of sleep and to improve well-being in the elderly. However, it is not known whether CALED mimicking a normal circadian rhythm has the same benefits for elderly persons with frailty or dementia. The investigators therefore want to test the effects of CALED in elderly people with frailty and mobility disabilities and/or dementia living in elderly housing. The investigators hypothesise that CALED can improve sleep and well-being in both elderly with frailty and dementia.
This study will investigate whether converting patients from FDA approved immediate-release tacrolimus to FDA approved extended release tacrolimus (Envarsus) reduces neurological side-effects, improves quality of life, and enhances adherence. A select group of elderly (> 60 years of age) patients, who are especially sensitive to tacrolimus-related adverse (AEs) effects, will be provided the opportunity to convert to Envarsus with this study.
In patients with chronic renal failure, a well-functioning vascular access is essential for hemodialysis treatment. Native arteriovenous fistula (AVF) is the first-choice of vascular access, due to a lower incidence of complications and better long-term patency as compared to prosthetic arteriovenous fistula. With the incidence ranging between 6-60%, AVF aneurysm (AAVF) is a common complication of native AVF. According to Kidney Disease Outcomes Quality Initiative (K/DOQI) guidelines, asymptomatic aneurysms are indicated for conservative treatment, but precise recommendations when and how to intervene in available guidelines are missing. Several surgical (remodeling, resection and substitution, ligation) and endovascular techniques have been described in the AAVF treatment, but there is currently no prospective randomized study comparing these techniques. In 2008, our team published the first experience with a new surgical method of AAVF treatment - aneurysmorrhaphy with external porous prosthesis (Provena©, BBraun). This therapy was validated in several studies and has shown a good long-term patency and a minimal incidence of complications. AAVF aneurysmorrhaphy can be performed with or without an external porous prosthesis (Provena©, BBraun). The use of external prostheses reduces venous wall shear stress, turbulent flow, endothelial damage, and thrombus formation, which should improve vascular patency and reduce the risk of AVF re-aneurysm. So far, there is no prospective randomized study comparing the effect of external porous prosthesis on AVF patency and the incidence of postoperative complications.
This is an open label, randomized Phase II study to determine whether Mycophenolate mofetil (MMF) given over 22 months meaningfully decreases the size of participants' HIV reservoir. In addition to primary safety endpoints, the following hypotheses regarding drug efficacy will be tested: 1. MMF will be well tolerated and will not decrease adherence to or antiviral efficacy of ART. 2. Peripheral CD4+ T-cell counts and percentages will not meaningfully decrease during treatment with MMF and ART. 3. There will be no excess risk of opportunistic infections in MMF-treated study participants. 4. MMF therapy will lead to a progressive decrease in reservoir size over 22 months of treatment. 5. MMF therapy will lead to a continual shift in HIV reservoir composition from primarily effector memory CD4+ T cells (TEM) and central memory CD4+ T cells (TCM), to primarily stem cell like memory (TSCM) and naïve (TN) CD4+ T cells. 6. MMF will eliminate detectable measures of the HIV reservoir, including by cell-associated DNA/mRNA and quantitative viral outgrowth. 7. MMF will not decrease the humoral immune response to routine annual influenza vaccination.
New mobile Health (mHealth) technology creates an opportunity to approach travel medicine research in a different way, revolutionising our understanding of risks to travellers. Using mHealth technology, the Epidemiology, Biostatistics and Prevention Institute (EBPI), University of Zurich (UZH), developed a TRAVEL app in collaboration with the Eidgnössische Technische Hochschule (ETH) Zurich. By using this new technology, an extensive collection of data (prospective collection of individual travel behaviour and experienced health events, mapping the travel itinerary via global positioning system (GPS), linking to publicly available local weather data and data on disease endemicity) can be combined and an unprecedented abundance of information on travel behaviour and experienced risks can be obtained. These data will allow a much better understanding of travel risk profiles using cluster analysis. By simultaneously recording health outcomes, the relationship between travel risk profiles and health events can be assessed. In this study, the investigators will address several major shortcomings in travel health in tropical and subtropical destinations by improving the understanding of poorly assessed and potentially underestimated health threats (e.g. risk of accidents and injury, mental health disorders), and travel risks specific to elderly travellers and travellers with chronic conditions. These findings will directly feed back into individual travel advice given by practitioners in Switzerland and finally world-wide.
Study of immunosuppression biomarkers in patients with ARDS or cardiogenic shock with ECMO / ECLS, compared to patients with ARDS or cardiogenic shock without ECMO / ECLS
Bloating, gas, pain and diarrhea are common complaints. Routine investigations are negative; these patients are labeled as IBS. In these patients, whether testing for carbohydrate malabsorption or small intestinal bacterial overgrowth (SIBO) is useful is unclear. Investigators aim to assess the prevalence of SIBO, fructose and lactose intolerance, the usefulness of breath tests, and predictive value of pre-test symptoms.
