Filter by:Febrile neutropenia (FN) is a major life-threatening treatment complication in cancer patients undergoing intensive chemotherapy. Endogenous flora is considered to be one of the main sources of infections during neutropenia. Competitive inhibition of gut mucosal colonization by pathogenic microorganisms using synbiotics could represent one of the potential options for its prevention. Synbiotics represent combination of two components: probiotics and prebiotics. Probiotics are live microorganisms, which in form of drugs or food supplements administered at a sufficient dose help to maintain health beneficial microbial balance in the digestive tract of a human or other host. Prebiotics are food ingredients nondigestible for our digestive enzymes, but can be fermented by bacteria in our bowel and this way selectively stimulate growth or activity of specific saccharolytic bacterial strains. These changes in composition of our microflora may bring benefits on host well-being and health. Based on the results of human and animal studies, probiotics probably can not only decrease the level of gut colonisation with pathogenic bacteria, but may also lead to reduction in the duration of neutropenia, accelerate the restitution of the intestinal mucosa and boost immunity. Despite a significant number of studies on probiotics still only little evidence of their safety especially in immunocompromised patients is available. To help find new options for increasing quality of healthcare for children cancer patients and also to evaluate safety of this new approach investigators designed double-blinded placebo controled multicenter study aimed to decrease the number of febrile episodes using prevention with synbiotic.
Health care systems are increasingly using outpatient care for patients with advanced cancer disease with complex needs, limited life expectancy, and need for palliative care. Family caregivers are centrally important, but are often insufficiently prepared for the caregiving role, and experience psychological distress and physical symptoms. We hypothesize that a psycho-educational intervention during ongoing palliative care will support family caregivers' wellbeing and decrease negative consequences of caregiving. The intervention, which has been developed in steps through a series of studies based on theoretical, methodological, and empirical work, was delivered in a group format 2013-2014. Family caregivers were invited to meet in a group for 2 hours once a week for 3 weeks. Each meeting had a specific topic presented by a member of the palliative care team (physician, nurse, and social worker). The meetings addressed multi-dimensional issues in dialogue with the participants. The overall aim of this ongoing project is to investigate short and long-term effects of the intervention delivered by health professionals at ten specialized palliative home care units. Multiple methods are now being used, including a randomized controlled trial (RCT). In total, 270 family caregivers have been requested to answer a questionnaire at four time points: at baseline, upon completion and again 2 months after completion of the intervention, and 6 months after the patient's death. The primary outcome variable is preparedness for caregiving, and the secondary outcome variables cover aspects of wellbeing including competence and reward, caregiver burden, health, anxiety and depressive symptoms, and grief. These data will be complemented with interviews. The project has the potential to contribute knowledge about the development of support for family caregivers, not only in specialized palliative care but also in other contexts such as elderly care and general home care services.
The purpose of this research study is to determine the feasibility of using positron emission tomography (PET) imaging technology to image cancer with [18F]FluorThanatrace ([18F]FTT), a new radioactive tracer compound that has been developed that images poly(ADP-ribose) polymerase 1 (PARP-1) activity.
The purpose of this study is to determine whether taking daily, dietary supplements of cocoa extract (containing cocoa flavanols and theobromine from the cocoa bean) and/or a standard multivitamin reduces the risk of developing cardiovascular disease (including heart attack, stroke, coronary revascularization, unstable angina or acute coronary syndrome (ACS) requiring hospitalization, carotid artery surgery, and peripheral artery surgery or angioplasty, and cardiovascular mortality) and cancer.
The Fernald Community Cohort consists of the 9782 persons who were enrolled in the Fernald Medical Monitoring Program (FMMP) (1990-2008). The initial comprehensive examination conducted as part of the Fernald Medical Monitoring Program (FMMP) began in the autumn of 1990. The FMMP provided 9,782 initial examinations and 42,775 re-examinations. An extensive computerized database and biospecimen repository was created to provide research resources for future studies. All questionnaire, examination and diagnostic procedure data collected from the FMMP were [coded by certified medical record coders,] double entered with verification into a SAS database on site of the examinations. Cryo-preserved blood and urine samples were collected at enrollment and at various intervals throughout follow-up. At the first examination three 1-ml aliquots of whole blood, plasma, serum, urine and urine with buffer were obtained from each participant (15 aliquots per person) for future analyses. Additional whole blood and serum was obtained in 1996-1997 and 2006-2008. Specimens have been stored in -80 degree freezers; over 160,000 biospecimens are in the archive. Since 1994, the FCC has had an established procedure for sharing data and biospecimens with qualified researchers. Both the policy and application forms can be found at www.eh.uc.edu/fmmp/research.
This is a Phase III multicentre randomized controlled trial (RCT) to evaluate the impact of tranexamic acid (TXA) on perioperative blood transfusion in patients undergoing liver resection. The rationale for this study includes: (1) experimental evidence supporting the use of TXA in other surgical populations; (2) lack of evidence in patients undergoing liver resection; (3) clinical uncertainty and extensive support amongst hepatobiliary surgeons, anaesthesiologists, and hematologists for this proposed trial; (4) a feasible and efficient study design; and (5) the importance of the question: incidence of blood transfusion in patients undergoing liver resection is high, and the consequences serious. The sample size for this study is 1230 participants.Participants enrolled in the prior Vanguard study will proceed directly into the RCT.
The objectives are to assess the safety and tolerability of 6 vaccine doses of MVX-ONCO-1, administered sub-cutaneously (injections and capsules implantations), in patients with advanced metastatic solid tumor in progression who are not or not any longer amenable to any standard therapy of their tumour disease.
The goal of this study is to develop a new, local system that will use special tests based on patients' genetic makeup to better tailor cancer care at the University of New Mexico Cancer Center. The Food and Drug Administration has already approved over forty (40) drugs to treat cancer patients based on specific genetic makeup, and more agents are in development that will support this new approach to treatment, often referred to as "personalized medicine." The goal of performing specific tests on patients' genetic material is to discover tumor-specific, single nucleotide variations (SNVs) and other forms of genetic changes (called epigenetic changes) that can be detected when comparing normal tissue and tumor tissue. This can help guide cancer care decisions that may be more effective for patients. These will be called clinically actionable findings, or CAF. Additional health related findings may be made, not related to cancer but to other conditions, diseases or syndromes. These are called secondary findings (SF). In this study the investigators will also measure how often they find SF and will discuss their possible impact on other aspects of patients' health. If patients want to know about these findings, they will be discussed with a panel of experts including genetic counselors. Finally, the investigators will compare how often CAF and SF differ from those identified in nationwide samples.
The goal of this study is to determine the feasibility, reliability, and validity of administering the Geriatric Assessment Tool using these two different computer based survey platforms, REDCap and Support Screen. The development of a computer based Geriatric Assessment Tool has the potential to improve research and clinical practice by providing an efficient user friendly means to collect and analyze data for geriatric oncology patients.
The ASPREE Cancer Endpoint Study (ACES), an ancillary study of the ASPirin in the Prevention of Events in the Elderly (ASPREE) Study, will allow for the examination of the effect of daily low-dose aspirin (100 mg) compared to placebo, on specific DNA biomarkers and selected specific incident and recurrent cancer and metastases. The establishment of this ACES biobank will allow for the exploration of DNA-related molecular mechanisms of aspirin's protective effect against cancer, cancer associated mortality and metastases, using blood or saliva DNA specimens, urine, and tumor tissue.
