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.
The objective of the study is to assess the incidence of safety outcomes in patients treated with Pipeline™ Flex embolization device with Shield Technology™.
Introduction- Hospital acquired infections (HAI) are a major cause of morbidity and mortality and increase health care costs. Critically ill patients are particularly susceptible to these infections and have an even higher mortality. One intervention that has gained much interest in the medical literature for reducing infection rates and deaths from HAIs is selective decontamination of the digestive tract (SDD). SDD involves the application of antibiotic paste to the mouth, throat, stomach and a short course of intravenous antibiotics. The evidence supporting the use of SDD for saving lives and preventing infections is actually quite strong. However, health care professionals in many parts of the world have refrained from using SDD due to fears of the effects of overuse of antibiotics on the frequency of infections with resistant bacteria such as multi-resistant Gram negative organisms, MRSA and Clostridium difficile. SuDDICU is a cross-over, cluster randomised trial comparing the effect of using selective decontamination of the digestive tract (SDD) plus standard care, to standard care alone on hospital mortality in patients receiving mechanical ventilation in the intensive care unit (ICU). Secondary outcomes include an ecological assessment and a long-term health economic analysis.
To evaluate the point accuracy of the Abbott Sensor Based Glucose Monitoring System when used at home by children with diabetes.
The purpose of this study is to evaluate the functional vision of 2 daily disposable silicone hydrogel contact lenses using Time Controlled Visual Acuity (TCVA) measurements at high luminance and high contrast after 10+/-3 days of wear post 3 hour exposure to a reduced humidity environment.
The aim of this study is to compare two licensed asthma inhalers and to then evaluate the safety of reducing treatment when patient's asthma is in control. The inhalers used in this study are the Seretide® 250 Evohaler®, which is widely used in UK, and a recently licensed inhaler called Flutiform®. National guidelines recommend that asthma medication should be increased when patients are experiencing worsening of their asthma, and reduced when asthma is in control. However, it is likely that in daily clinical practice some patients are over-treated. It is therefore necessary to conduct more studies which demonstrate that reducing treatment dosage can be done safely. This study has two phases. In the first phase the investigators aim to recruit 224 patients through approximately 40 clinics in the UK and Ireland. One third of these patients will be selected in random to use the high dosage Seretide® 250 Evohaler® and two thirds will use high dose Flutiform® 250 inhaler for 12 weeks. At the end of phase 1 the investigators will compare how well asthma was controlled between the two groups. After phase 1 those patients who used Flutiform and did not have any problems with their asthma can participate in phase 2. In phase 2 half of the patients will stay on high dosage Flutiform 250 and half will be switched to the medium dosage Flutiform 125 inhaler. At the end of phase 2 the investigators will compare asthma control between the two groups. This study will be conducted by Research in Real Life Ltd (Cambridge, UK) with partial funding from Napp Pharmaceuticals Ltd. The estimated total duration of the study is 18 months and each patient will spend a maximum of 6 months in the study.

Radiotherapy (RT) is an important treatment for prostate cancer with over 10,000 men receiving RT per year in the UK. Prostate RT aims to deliver radiation dose to the prostate to kill cancer cells whilst minimizing the dose given to surrounding normal tissues, such as the bladder or the rectum. Radiation is delivered in a number of daily treatments which are called 'fractions'. The position of the prostate varies each day and during the radiation delivery. To accurately aim the radiation the prostate needs to be located before daily treatment. Clarity is an ultrasound image guidance system that locates the prostate and monitors its position during treatment. Ultrasound does not give a radiation dose, is non-invasive, provides fast imaging and can easily visualise soft tissues. Before Clarity is implemented the investigators wish to ensure that it can accurately locate and monitor the prostate by comparing Clarity with marker-based techniques in 24 patients. Patients receive markers as part of other trials which are currently recruiting at The Royal Marsden (for example, patients in the DELINEATE trial and the PACE trials receive implanted gold markers and patients in the PROSPARE trial have received electromagnetic markers). Patients who have received or will be receiving markers as part of other studies will be asked to also to take part in this study. This means that there will be no additional intervention for patients as a result of this study. Clarity will be considered a safe and effective imaging system if the mean and standard deviation of the differences between Clarity measurements and marker measurements, of prostate position, are less than 1mm. It is possible that markers will influence the Clarity measurements. To find out if this happens, the mean and standard deviation of Clarity measurements in a group of 24 patients without markers to the group with markers will be compared. Primary Aim: To evaluate the accuracy of Clarity ultrasound image guidance system for prostate motion estimation during treatment (intra-fraction), by comparison with implanted marker-based image guidance techniques. Primary Hypothesis: Clarity can be safely used to deliver radiotherapy using similar (within 1mm) treatment margins to those that would be employed if fiducial markers based image guidance techniques were used.

A randomized, sham-controlled, single-centre pilot investigation designed to compare two parallel groups, gammaCore®-G (active treatment) and a sham, (inactive) treatment in subjects with FGIDs.
Around 20% of women who receive breast radiotherapy (RT) experience moderate to severe breast hardening and shrinkage. These side-effects have been shown to be important factors influencing quality of life after breast radiotherapy. It is thought that the likelihood of developing these side-effects is related to the presence of underlying genetic differences in patients. In order to identify these genetic differences, the severity of side-effects needs to be accurately measured. Currently, clinical assessments are conducted by a clinician but this is not specific enough to be able to relate development of breast shrinkage and hardening to genetic differences. For example, clinical assessment often fails to distinguish between hardness due to swelling (known as oedema) and hardness due to generalised radiation-induced scarring (known as fibrosis). Ultrasound techniques, however, may be able to help quantify and characterise radiotherapy-associated changes in breast tissue allowing for better correlation with genetic abnormalities. Once genetic changes can be identified, adjustment of breast RT treatments (or add drugs) to help reduce side-effects in women at higher genetic risk of side-effects may be possible. This study tests the ability of two forms of ultrasound, shear-wave elastography (USE) and ultrasound backscatter spectroscopy (UBS), to quantify and characterise breast shrinkage and firmness with a view to using these techniques to measure the late side-effects of breast RT to study the underlying causes of radiotherapy toxicity. Principle research question: Can a new ultrasound technique (shear wave elastography) measure radiation-induced side-effects in women who have received breast radiotherapy?
