Preterm infants face an uncertain future because premature birth often leads to problems with brain development and can cause cerebral palsy. A trial needs to be done to see if Magnetic Resonance Imaging (MRI) helps families and professionals by predicting long term problems more accurately, allowing better targeting of care to children with problems and reassuring the parents of normal babies. This programme will provide the evidence-base for the National Health System (NHS) policy on the use of magnetic resonance imaging of the brain for preterm infants.
The aim of the study is to evaluate the safety and effectiveness of the IOPtiMate (OT-135P) in Laser Assisted Non-Penetrating Glaucoma surgery in Open-Angle and Pseudoexfoliative Glaucoma patients.
There are two types of external radiation treatments (proton beam and photon beam). As part of the participant's treatment, they will receive radiation to the entire central nervous system (CNS); this is known as craniospinal irradiation (CSI). In the past, photon radiation therapy has been used for CSI. In this study we will be examining the effects of proton beam radiation therapy. Studies have suggested that this kind of radiation can cause less damage to normal tissue than photon radiation therapy. The physical characteristics of proton beam radiation let the doctor safely deliver the amount of radiation delivered to the tumor that is normally delivered through standard therapy but spare more normal tissue in the process.
Ageing dramatically affects immune function; this phenomenon is known as immunosenescence and partly explains the increased susceptibility for infection in older individuals. Vaccination is recommended to protect older people against influenza, but immunosenescence also reduces the efficacy of vaccination. Probiotics are beneficial bacteria, which can be consumed and which have a long and safe record of use in humans. Often they are taken together with prebiotics, which are carbohydrates that provide a food source for the beneficial bacteria when they reach the lower gut. There is particular interest in the positive influences of pre- and probiotics in older people, who are subject to alteration in gut microflora composition as well as immunosenescence. The PRIMAGE (Probiotics, immunity and ageing) study will examine the effect of a prebiotic and probiotic mix on the immune response to influenza vaccination in young and older subjects, and is funded by BBSRC DRINC. It will involve 60 young (18-35y) and 60 older (65-85y) subjects recruited from the local Reading community. Participants will take a pre- and probiotic mixture or a placebo for a total of 8 weeks. The probiotic is not currently commercially produced, but has been demonstrated to have particular ecological fitness and anti-pathogenic effects in the gastrointestinal tract in old age. A suitable prebiotic will be selected on the basis of ability to promote optimal growth and survival of this probiotic. After 4 weeks on the treatment, the subjects will receive an influenza vaccination. Blood, saliva and stool samples will be taken before treatment, and at 4, 6 and 8 weeks after commencement. The samples taken at 6 and 8 weeks will be used to assess the immune response to the vaccination. A wide range of immune parameters will be assessed, taking into account the age-related shifts in immune cell populations.
This study will investigate the efficacy of inhaled TOBI treatment for early infections of P. aeruginosa in paediatric patients with cystic fibrosis.
The purpose of this study is to examine the effects of glucocorticoid administration following traumatic memory reactivation on psychiatric symptoms in veterans with combat-related PTSD, in addition to examining the effects of glucocorticoid administration following traumatic memory reactivation on physiological responses to veteran's personal combat memories. The following hypotheses will be tested: 1. Subjects who receive an exogenous glucocorticoid after traumatic memory reactivation will demonstrate fewer PTSD and depression symptoms one week later, compared to those who receive a placebo after traumatic memory reactivation. 2. The glucocorticoid reduction effects will be cumulative; that is, reduction will persist, and further post-reactivation glucocorticoid administration will further reduce symptoms 3. Decreases in PTSD and depression symptoms will persist at 1, 3, and 6 months for subjects receiving an exogenous glucocorticoid compared to those subjects receiving placebo 4. Subjects who receive an exogenous glucocorticoid after traumatic memory reactivation will demonstrate decreased physiological responses one week later, compared to those who receive a placebo after traumatic memory reactivation. 5. As with the psychological measures, suppression of the physiological measures will demonstrate both persistence over time and accumulation with subsequent post-reactivation glucocorticoid administration.
Postcancer fatigue is a severe and invalidating problem, impairing quality of life. About 20 to 40% of the patients remain fatigued, at least one year after successful cancer treatment. Fortunately, there is an effective treatment for postcancer fatigue; cognitive behavior therapy. However, no cause for postcancer fatigue has been identified yet. The aim of the study is to identify factors that (partly) cause postcancer fatigue to improve the theoretical understanding of fatigue and to improve the diagnostics of fatigue, predict therapy outcome, and facilitate other treatment options. In this study, disease-free fatigued cancer patients, who finished treatment for cancer at least one year and maximally ten years ago, will be approached for this study. They will be compared to non-fatigued patients. First, a baseline assessment will take place. Magnetic resonance imaging of the brains will be performed to assess brain volume and magnetic resonance spectroscopy will be performed to measure the concentrations of specific substances in the brains. Changes in the volume of parts of the brains have been observed in (non-cancer) patients with the chronic fatigue syndrome (CFS), in comparison with healthy controls. In addition, abnormal concentrations of specific substances have been observed in patients with CFS compared to healthy controls. To assess muscle fatigue, a two-minute endurance test of the upper arm will be administered at maximal voluntary contraction. Next to differences in the brains, CFS patients showed (central) muscle fatigue. A maximal exercise test on a bicycle will be performed to assess physical fitness. Physical activity in fatigued cancer survivors is decreased, compared to healthy controls. It is not known whether physical deconditioning originated during the cancer treatment is the reason why these patients are still less active. In addition, patients and controls will wear an actometer for two weeks to register baseline daily physical activity and for an additional 5 days after the maximal exercise test, to assess the effect of exercise on the daily physical activity. Finally, patients and controls will complete standardized questionnaires and will perform neurological/psychological tests, like a reaction time test and a short time memory task, at baseline. The results of the non-fatigued and the fatigued patients will be compared at baseline. For the non-fatigued participants, the study will be finished after the baseline measurements. The fatigued participants will start with cognitive behavior therapy immediately after the baseline measurements or after 6 months, depending on the randomization. At the end of the therapy, after six months, or after 6 months of waiting for cognitive behavior therapy, a second assessment will take place, comparable to the baseline measurements. These results will be compared with the baseline situation to analyze the effect of cognitive behavior therapy on the (possible) causes of postcancer fatigue.
RATIONALE: Sunitinib malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Giving sunitinib malate before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving sunitinib malate after surgery may kill any tumor cells that remain after surgery. It is not yet known whether undergoing immediate surgery or surgery after sunitinib malate is more effective in treating patients with metastatic kidney cancer. PURPOSE: This randomized phase III trial is studying immediate surgery to see how well it works compared with surgery after sunitinib malate in treating patients with metastatic kidney cancer.
This study will look at the treatment effect of DiaPep277 on preservation of beta-cell function, as defined by meal-stimulated secretion of insulin. DiaPep277 is a peptide that changes the way the immune system behaves, stopping its attack on the beta-cells. Adults (>20 years) with newly diagnosed (<6 months) type 1 diabetes will be treated with 10 injections of DiaPep277 or Placebo over a 2-year treatment and follow-up period.
The purpose of this study is to learn more about how the body stores fat in and around organs (for example in the liver) and why this affects some people's health more than others. Understanding this may lead to better treatments for diseases such as diabetes and cardiovascular disease.
