There are about 25435 clinical studies being (or have been) conducted in United Kingdom. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Swallowing function is controlled by two swallowing centres (one on each half of the brain). There is a dominant and non-dominant swallowing centre. Damage to any part of the brain can lead to swallowing problems, for example in strokes. Recovery of the ability to swallow is associated with increased activity (compensation) over the undamaged centre. The cerebellum is an area of the brain involved in the control and modulation of muscle movements. It is found at the back of the skull. Over the past few years studies have tried to improve swallowing function using techniques to stimulate regions of the brain and encourage compensation. Repetitive transcranial magnetic stimulation (rTMS) is a technique which can temporarily increase or suppress activity over regions of the brain. This study will use cerebellar rTMS to attempt to increase activity over the cortical swallowing centres. It will also temporarily suppress activity over the dominant swallowing centre (a virtual lesion) before using cerebellar targeted rTMS to attempt to reverse this suppressive electrical and behavioural effect. The investigators aim to compare the effectiveness of rTMS over the two halves of the cerebellum to rTMS over one half of the cerebellum in increasing activity over the swallowing centres and reversing the suppressive effects of low frequency rTMS 'virtual lesion' over the dominant swallowing centre.
Following successful CTO PCI, a multitude of physiological and anatomical changes take place. Contemporary techniques such as dissection/re-entry or lumen-lumen wiring may influence the immediate and longer term follow up of these features. It is not known whether changes in this level of physiology and anatomy in the context of CTO vessels correlate with each other, or with quality of life and exercise capacity. This study aims to take physiological measurements of absolute coronary flow, resistance and pressure and intra-coronary imaging immediately after successful CTO PCI. The investigators will relate these to each other and to the method of revascularisation, comparing changes in these groups at three months follow up. QoL measurements, and exercise testing will be carried out to see if there is a relationship between physiological and anatomical changes with exercise capacity and quality of life. Results from this study could shed light on optimisation of CTO PCI procedural and clinical outcomes.
Intraoral Neuromuscular Training for Treatment of Snoring Objective Studies show that improving pharyngeal muscle tone can ameliorate obstructive sleep apnoea (OSA) and snoring. The study uses an intra-oral stimulation device (SnooZeal) aimed at a population of snorers. The aim of this study is to assess the efficacy of intra-oral neuromuscular stimulation training during wakefulness on snoring. Methods This is a prospective study, recruiting up to 200 patients from the sleep clinics. In this study, subjects will use the intra-oral stimulation device once a day for 20 minutes each time for a period of 6 weeks. During these 6 weeks, subjects will complete a daily diary of the device use and any side effects or adverse events. Partners also complete a daily snoring score. Subjects will be followed-up for a further 2 weeks after treatment. They will complete Pittsburgh Sleep Quality Index (PSQI) and subjective sleep quality questionnaires for a further 2 weeks. Partners will also complete the post treatment snoring scores. Sleep study will be repeated. Outcome measures The objective evaluation will be based on pre- and post-treatment sleep studies, visual analogue scale (VAS) snoring scores, PSQI and subjective sleep quality questionnaire. All side effects and adverse events will be reported and acted upon according to the risk management structure.
Patients undergoing major head and neck surgery often develop breathing difficulties as a result of build up of sputum and difficulty taking deep breaths. Often as part of the surgery patients may also require a tracheotomy tube (a temporary tube placed into their airway) which is removed around 5-7 days after the operation. The presence of this tracheostomy tube increases the patient's risk of developing breathing problems, especially difficulty clearing sputum and reduced lung volumes. To reduce the risk of developing these problems, different forms of oxygen therapy and humidification are used. This normally involves using oxygen masks, nebulisers and other medications to help loosen the sputum and maintain blood oxygen levels. Another method of giving oxygen and humidification is through the use of AIRVO, which delivers the air / oxygen to the patient at higher rates as well as warming and humidifying the air. The aim of this study is to compare the AIRVO system to standard care in a small sample of patients (20 patients) undergoing major head and neck surgery involving insertion of a tracheostomy tube. The study will compare rates of breathing complications (e.g. pneumonia, reduced lung volume) as well as comparing the time to remove the tracheostomy tube and the time the patient is required to stay in hospital. These results will then be used to develop a larger funded study.
The aims and objectives of the clinical feasibility trial are: - to investigate the potential for VR to reduced perceived pain and anxiety during painful dressings changes in a small sample of burns patients; - to measure the impact of the interventions on objective indicators of pain and distress during dressing changes within the small sample - to assess pain medication use during virtual reality interventions - to compare the above effects and experiences across two conditions within each participant: an active version of a virtual reality intervention, and a 'control' condition of no intervention; - to assess the perceived usability, acceptability, engagement with and enjoyment of the virtual reality intervention to the patients - to consider the apparent feasibility of the virtual reality intervention within a Burns Unit inpatient setting during painful dressing changes 4. Design This is an exploratory feasibility study with a small clinical sample of burns patients and staff caring for them, in a single burns unit setting, employing mixed methods and a repeated measures design to achieve the aims set out above.
The primary objective of the study is to evaluate the efficacy of mavrilimumab (KPL-301) versus placebo, co-administered with a 26-week corticosteroid taper, for maintaining sustained remission for 26 weeks in subjects with new onset or relapsing/refractory giant cell arteritis (GCA).
The aim of the research project is to develop, deliver and assess the feasibility of a nurse-led allergy clinic in primary care, taking into account population, geographical area and needs of healthcare in the area chosen. It is widely acknowledged that the majority of cases of mild to moderate allergy could be adequately dealt with in primary care, by a healthcare professional with the appropriate expertise and knowledge of allergy. The provision of allergy care in the community could potentially have a beneficial impact on health care and patient outcomes. The project will comprise the set up and delivery of a nurse led allergy clinic in primary care and use a mix of qualitative and quantitative methods to evaluate the feasibility of the clinic. This will include the use of a series of validated questionnaires e.g. satisfaction, condition specific quality of life and economic cost questionnaires, as well as face to face interviews. The research will collect data to see if this clinical intervention is feasible and allow audit of the clinical intervention. This will also enable the researchers to understand patients lived experiences of accessing allergy care and the effect of allergy on quality of life and impact of allergy care.
The treatment of lymphoedema and its associated complications represent a considerable drain on increasingly limited NHS resources. Intermittent pneumatic compression, specifically the LymphAssist (Huntleigh Healthcare), represents an innovative treatment for this condition but the efficacy of this device needs to be investigated via robust clinical research.
This study is a prospective feasibility study with the addition of a retrospective cohort study on the the expression of microRNA in urine in endometrial cancer patients.
The conventional hypoxic challenge test might not predict 'fitness-to-fly' equally well in all patients. Patients at risk of hypercapnia with supplemental oxygen are not well studied. Th investigators will study children who have either neuromuscular weakness or central hypoventilation and who require nocturnal or intermittent daytime ventilator support. The study also aims to assess feasibility of a randomised controlled trial (RCT) comparing the standard hypoxic standard test to a modified test designed to better suit children with type two respiratory failure.
