NCT ID: NCT03305250 Not yet recruiting - Fabry Disease Clinical Trials

Arrhythmia Burden, Risk of Sudden Cardiac Death and Stroke in Patients With Fabry Disease

Start date: January 2018
Phase: N/A
Study type: Interventional

Fabry disease (FD) is a genetic disorder that leads to progressive accumulation of fat or 'sphingolipid' within the tissues, including the heart muscle and conductive tissue. Improvements in the detection of FD, together with more organised clinical services for rare diseases, has led to a rapid growth in the disease prevalence. Earlier and more frequent diagnosis of asymptomatic individuals before development of the disease itself has focused attention on early detection of organ involvement and closer monitoring of disease progression. Moreover, the introduction of enzyme replacement therapy within the last two decades has changed the natural history of FD as follows: a) increased life expectancy; b) improved morbidity; c) modification of the main cause of morbidity and mortality from renal (kidney) to cardiovascular (heart) events, including heart failure, abnormal heart rhythms, stroke and sudden death. Although symptoms such as palpitations and blackouts are extremely common, information on the frequency of proven abnormal heart rhythms is limited. In addition, the rate and appropriateness of implantation of life-saving devices is very variable, including pacemakers to boost the heart when too slow and cardio-defibrillators that stop the heart when too fast. The main markers of risk in similar diseases such as hypertrophic cardiomyopathy cannot be used in FD. While patients are routinely followed up in clinic with heart tracings and echocardiography (ultrasound of the heart), a recent small study has emphasised that these tests under-estimate the burden of abnormal heart rhythms in patients with advanced FD. The use of continuous heart monitoring with an implantable loop recorder (ILR) has led to a significant change in treatment in 13 out of 15 of FD patients. The investigators believe that more frequent use of ILRs will identify a greater need for change in therapy in many more patients than currently treated, with the aim of reducing morbidity and mortality in this patient cohort. In addition this will provide valuable data to inform an estimate of future risk for these patients.

NCT ID: NCT03305237 Not yet recruiting - Obesity Clinical Trials

The Meal Time Study

Start date: October 2017
Phase: N/A
Study type: Interventional

This weight loss study will investigate the impact of calorie distribution across a day (large breakfast meals and smaller evening meals versus small breakfast meals and large evening meals) on body weight, and physiological and behavioral mechanisms regulating energy balance. Participants will undergo 2 x 4 week energy restriction protocols in a randomized cross over design; big breakfast (45% of calories in the morning meal, 20% at dinner) and big dinner (45% of calories in the evening meal, 20% at breakfast). We predict that timing of eating will influence energy balance, because morning energy expenditure is amplified in comparison to the evening. This study will allow us to assess whether the increased energy expenditure in the morning is linked to natural biological circadian rhythm or behavioral adaptions.

NCT ID: NCT03304197 Recruiting - Healthy Clinical Trials

Hydration and Exercise Performance in Cycling

Start date: September 11, 2017
Phase: N/A
Study type: Interventional

This study will evaluate the effects manipulating ingested fluids can have on cycling performance. There will be 4 different conditions.

NCT ID: NCT03303625 Not yet recruiting - Clinical trials for Respiratory Tract Infections

A Study to Evaluate the Safety, Tolerability and Immunogenicity of an Investigational RSV Vaccine Candidate (Ad26.RSV.preF) in Adults 18 to 50 Years of Age, and RSV-seropositive Toddlers 12 to 24 Months of Age

Start date: October 16, 2017
Phase: Phase 2
Study type: Interventional

The purpose of this study is to assess the safety and tolerability of an intramuscular regimen of two doses (1*10^11 viral particles [vp]) of an investigational respiratory syncytial virus (RSV) vaccine candidate (adenovirus serotype 26 respiratory syncytial virus pre-fusion conformation stabilized F protein [pre-F] [Ad26.RSV.preF]) in adults aged 18 to 50 years and RSV-seropositive toddlers aged 12 to 24 months.

NCT ID: NCT03303547 Not yet recruiting - Clinical trials for Adenocarcinoma of the Rectum

Concordance in MRI and Pathology Diagnosis of Extranodal Tumour Deposits

Start date: November 2017
Phase: N/A
Study type: Interventional

Predicting prognosis in rectal cancer and determining indications for neoadjuvant treatment is an ongoing challenge for colorectal multidisciplinary teams (MDTs). Staging is almost universally based on the TNM system which, despite multiple changes and increasing levels of sub-classification and complexity, is still flawed in its ability to stratify patients and predict prognosis(1-3). Determining which patients will benefit most from neoadjuvant and adjuvant therapy is still controversial; NICE guidelines are open to interpretation(4) and there is significant geographic variation in the way patients are managed. The Aim of this study is to prove the accuracy of MRI diagnosis of ENTD and its adverse effect on prognosis.

NCT ID: NCT03303417 Active, not recruiting - Constipation Clinical Trials

Effect of Kiwifruit on Gastrointestinal Fluid Distribution and Transit in Healthy Volunteers

Start date: June 27, 2017
Phase: N/A
Study type: Interventional

Constipation is a widespread and common problem in which a person finds it difficult and/or painful to open their bowels. The current treatment is the use of medications called laxatives. Kiwifruit is a widely available food that has been shown to possess some laxative properties. The cause of this is unknown. Non-invasive medical imaging techniques such as Magnetic Resonance Imaging now allow taking pictures of the gut and its contents. Our research group specialises in these techniques and in this study we want to use such images to assess the changes induced in the gut contents by kiwifruit to improve our understanding of how it helps patients with constipation. The volunteers will be asked to undergo 2 studies in which they take either kiwifruit or placebo (sugary drink) two times a day for 2 days and then spend a study day with us where we will feed them some more kiwifruit/placebo and some normal food and image their gut at intervals. We will also ask participants to complete a stool diary to determine if they experience a laxative effect.

NCT ID: NCT03302663 Recruiting - Fetal Conditions Clinical Trials

The Value of Advanced Imaging Sequences for Fetal MRI in Clinical Practice

Start date: August 1, 2013
Phase: N/A
Study type: Interventional

This project is split into 4 sections: 1. Can improvements be made in the Magnetic resonance imaging sequences used to image the fetus in order to improve diagnostic accuracy? 2. Does 3T improve the quality and diagnostic value of fetal MRI when compared to 1.5T 3. Can fetal MRI be used to image the fetal heart? 4. Can fetal MRI be used to image the fetal Bones?

NCT ID: NCT03302013 Recruiting - Clinical trials for Primary Osteoarthritis of Knee Nos

All Ligaments Left In Knee Arthroplasty Trial

Start date: September 5, 2016

Compare the clinical and patient reported outcomes of the Vanguard XP Knee System to the Vanguard CR Knee System in patients with antero-medial osteoarthritis of the knee with an intact anterior cruciate ligament.

NCT ID: NCT03301948 Recruiting - Metabolic Disease Clinical Trials

Effects of a Single Day of Mixed Macronutrient Overfeeding on Energy Balance and Metabolic Responses

Start date: May 1, 2017
Phase: N/A
Study type: Interventional

Healthy male participants are recruited to observe potentially deleterious changes in appetite regulation and metabolic control. Participants will be provided with an energy intake representative of their daily requirements on the first day of one trial and will be provided with an additional 50% energy intake on the first day of another trial. Outcome variables will be assessed during the second day of each trial in response to a fixed mixed macronutrient meal tolerance test.
