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.
This study is a RCT to examine whether DHEA is capable of improving results for poor responders to ovarian stimulation during IVF treatment
Stroke and silent cerebral infarction are a real risk with thoracic enodvascular aortic repair (TEVAR). The investigator propose to prospectively observational study with enrolment of all patients undergoing TEVAR for thoracic and thoracoabdominal conditions including aneurysmal degeneration, Type B dissection and acute aortic syndromes over a 24 month period, equating to a minimum of 20-30 patients per year. Patients undergoing juxtra-renal and infra-renal aortic stenting will form a control group.
This study evaluates the effect of slow and deep breathing on lowering blood pressure in women with pregnancy-induced hypertension. Slow and deep breathing will be practised daily for 10 minutes from enrolment until the woman gives birth. This feasibility study aims to investigate the practicality of conducting a proposed future randomised controlled trial.
It is commonly known that high eye pressure is associated with glaucoma. However, there is also a theory that poor circulation to the eye is a contributing factor. Therefore, if we can increase the flow of blood to the eye, we may be able to stop people losing vision from this disease. Phosphodiesterase inhibitors (for example sildenafil, tadalafil, Viagra®, Cialis®) are drugs used to improve blood flow to certain parts of the body. They are commonly used on an ad-hoc basis to treat erectile dysfunction, in addition to problems with blood circulation to the lungs, fingers and toes. The majority of previous work in this field has been completed using insensitive, poorly reproducible techniques such as colour doppler ultrasound. Since then, a new imaging modality able to image blood flow in blood vessels without the need for the injection of contrast has entered clinical use. This initial pilot study is designed as a proof-of-concept study to investigate whether we can measure detectable changes in the blood flow to the retina and choroid at the back of the eye following ingestion of a phosphodiesterase inhibitor medication by healthy and glaucomatous volunteers already taking this medication for erectile dysfunction.
Clinical investigation of a medical device (CAVA) for recording eye movements. Patients suffering from diagnosed dizziness conditions will wear the device for 23 hours a day, for 30 days. The device will capture normal eye movement data as well as data corresponding to any dizzy events experienced. At the end of the trial, the data will be downloaded and a scientist will perform a blinded analysis of the data. Specifically, they will attempt to identify the dates on which dizziness was reported.
The team is investigating whether N-terminal pro B-type natriuretic peptide (NT-proBNP) and other cardiac markers are useful for predicting outcomes for patients undergoing vascular surgery. By measuring NT-proBNP before and after surgery, the investigators may be able to determine which patients are at risk of an adverse outcome, such as a heart attack or death.
This study determines the effect of aerobic and resistance exercise training on whole-body and skeletal muscle insulin sensitivity in south Asians and evaluate the mechanisms which contribute to improvements in insulin sensitivity after exercise training.
The study will aim to determine whether 6-weeks of using a SaeboGlove independently (with or without help from a carer) improves upper limb function (measured using the Action Research Arm Test score) in comparison to usual care alone in people with reduced active finger extension, severe upper limb disability and severe hand impairment after recent stroke.
Long QT syndrome (LQTS) is an inherited heart defect where the heart takes longer to recover between beats. LQTS is a known condition predisposing young footballers to sudden cardiac death (SDC). The existence of LQTS can be established by measuring the QT interval in an electrocardiogram (ECG). Currently pre-participation cardiac screening is performed in young athletes but players may only be screened at 16 years old using only a resting ECG, and a medical check including a questionnaire on family and medical history. However, the sensitivity and specificity of the screening to investigate underlying causes of SCD could be improved with the addition of an exercise stress test or cardiopulmonary exercise test (CPET). Certain abnormalities in the heart may only become apparent when the heart has been stressed (e.g. via exercise). This is particularly important as in young athletes these abnormal rhythms manifest during rest and recovery rather than at peak exercise. The CPET measures changes in the ECG in response to exercise that increases in intensity in a continuous manner until the participant cannot exercise any long. However, football is characterised by high- intensity bouts of exercise interspersed with low-intensity bouts or pauses. Therefore, the continuous test does not reflect the movement patterns of football and may not stress the cardiovascular system in a similar manner. To address this, intermittent graded exercise tests have been developed to reflect the intermittent movement pattern. As yet there is limited evidence on whether there are any differences in ECG changes during intermittent exercise. Specifically, it is not clear how an intermittent movement pattern might affect the QT interval.
This study will evaluate the effect of one minute of resistance exercise per day on muscular strength in adults. Half of the participants will undergo a 12-week home-based resistance exercise programme, while the other half will continue their usual lifestyle behaviour.
