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 purpose of this study is to explore the effect of Etoricoxib compared to Diclofenac on physical activity in RA subjects with early morning pain and stiffness.
Lung cancer is the most common cancer in the western world. Only 10 to 15 % of patients diagnosed with lung cancer are suitable for potentially curative surgical treatment. Despite surgery, recurrence of lung cancer still occurs. Aspirin potentially may help increase survival by altering the biochemistry of any potential remaining lung cancer cells. Most lung cancer occurs in smokers. Smokers are at increased risk of heart attacks and strokes. Aspirin has beneficial effects on the heart and brain, potentially reducing the incidence of heart attacks and strokes.
Cholesterol and blood pressure lowering tablets have been shown to be of benefit in patients with established high blood pressure. High blood pressure is a very common medical condition that can lead to vascular complications i.e. problems with the blood vessels in the body. One way of detecting early changes in these blood vessels as a result of high blood pressure is to measure their compliance/flexibility with a noninvasive technique known as ultrasound and with a simple blood test. The investigators are trying to establish whether these early changes in blood vessels can be significantly improved by the use of both a cholesterol and blood pressure lowering tablet at an earlier stage than is currently advised. The investigators hope that the early combination of these tablets will prove more effective than the use of a blood pressure lowering tablet by itself and therefore possibly reduce the risk of long term complications developing.
The investigators aim to show that quantitative analysis of doppler flow velocity waveforms i.e. ultrasound which is a nonāinvasive and very safe means of assessing blood flow; recorded in the proximity of terminal microvascular beds of interest, (i.e. the forearm and ocular circulation) can sensitively detect and track local changes in microvascular haemodynamics i.e. the function of the small blood vessels that are found in the back of the eye and in the forearm. The investigators also aim to relate change in the doppler spectral flow velocity waveform i.e. the ultrasound signal, in the central retinal artery to changes in geometry and tone of the vasculature (or changes in the structure and function of small blood vessels) in response to inhaled oxygen and carbon dioxide. The geometry and tone of the vasculature (or Blood Vessels) can be measured by taking photographs of the back of the eye.
Healthy kidneys clean your blood by removing excess fluid, minerals, and wastes. When your kidneys fail, harmful wastes build up in your body and your body may retain excess fluid. When this happens, you need treatment to replace the work of your failed kidneys. This may be with a dialysis machine using haemodialysis or with fluid in the abdomen or peritoneal dialysis. In peritoneal dialysis, a tube called a catheter is put in the abdomen wall and used to fill your abdomen with a cleansing liquid called dialysis solution. The walls of your abdominal cavity are lined with a membrane called the peritoneum, which allows waste products and extra fluid to pass from your blood into the dialysis solution. These wastes and fluid are removed from the body when the dialysis fluid is drained and replaced with a fresh solution. The tubes or catheters used to exchange the fluid are currently positioned using a general anaesthetic (with the patient awake) and an operation with a cut under the belly button. Newer techniques using local anaesthetic (with the patient awake and the area numbed) and requiring only a small cut in the skin have been used. No one has ever directly compared the two techniques. The investigators aim is to perform a direct comparison between the two techniques to look at the complications and time required for surgery and length of hospital stay required. The investigators will also look at the patients satisfaction and pain scores with each technique to help gather evidence as to which is likely to be the best technique to use from now on.
The investigators are investigating if surgical treatment of injuries to the tendon which straightens the finger tip gives a better functional outcome than treatment with a splint while the tendon heals.
The benefits of laparoscopic ("minimally invasive" or "keyhole") surgery for gallbladder removal (cholecystectomy) over open surgical procedures in terms of significant reductions in pain, scarring and recovery time are well accepted. In a conventional laparoscopic cholecystectomy however, the excised gallbladder still has to be extracted through the abdominal wall skin via a laparoscopic port site using an incision of 10mm or greater. Despite being much smaller than that required for open surgery, this incision is painful, leaves a scar and can result in a port site hernia to follow requiring further surgery to repair it. Recent attempts to further reduce the invasiveness of the surgical procedure have suggested performing the operation via an endoscope passed through the mouth and through an incision in the stomach wall - so called Natural Orifice Translumenal Endoscopic Surgery (NOTES). Unlike a skin incision, an incision in the wall of the stomach (gastrotomy) should give no pain, visible scar or herniation risk yet still allow access to the peritoneal cavity for surgical procedures such as cholecystectomy. Against this, it has the potential risks of contamination and leakage of gastric contents into the peritoneal cavity. Whilst the limitations of present technology make it very difficult to perform an entire cholecystectomy through the stomach wall in patients, endoscopic methods for closing a gastrotomy are available that are approved for use in patients (CE marked) and it is hypothesised that removing the excised gallbladder through the stomach in this way would avoid the problems of extracting it through the abdominal wall described above. Data are required to determine whether the extraction of the gallbladder via a gastrotomy rather than through the skin is safe, producing smaller scars and a better cosmetic result. A secondary endpoint would be to assess possible reductions in pain and recovery from this less invasive approach.
The One Hospital ClinicalService Project is an integrated system composed by a network of International Hospital Departments, a clinical data repository and a shared environment for the collection, management, analysis and reporting of clinical and diagnostics data from patients treated by Medtronic therapies or patients wearing Medtronic implantable devices used within their intended use. The One Hospital ClinicalService is composed by a suite of systematic, data-guided activities designed to bring about immediate improvements in health delivery in particular settings. Data are prospectively collected. An independent committee of physicians prospectively identifies key clinical questions on a yearly basis for development of quality improvement activities, analyses and publications. A charter, approved by Hospital Istitutional Review Boards or other Hospital entities, assigns the ownership of data to the centers and governs the conduct of the project and the relationship of the scientific committee and Medtronic. Hospital is the data controller, while Medtronic is the data processor on behalf of the Hospital. Data collected for quality improvement purposes may be mined to perform clinical research.
Irritable Bowel Syndrome (IBS) is a common condition characterised by abdominal pain or discomfort and altered bowel habit affecting up to 10% of the population. There are several groups of patients that are based on differing bowel patterns including IBS with diarrhea (IBS-D) and those with post infective IBS (PI-IBS) whose symptoms begin after an acute infection. Saccharomyces cerevisiae, the yeast used in bread making has been shown to reduce the duration of infectious diarrhoea. Part of the benefit maybe that it can destroy bacterial toxins. Recent studies suggest an increase in proteases (chemicals which breakdown proteins) in the stool of patients with IBS-D. The investigators think that this yeast may benefit patients with IBS-D and PI-IBS by reducing the amount of protease in stool. This is important because proteases have been shown to be potentially important in generating some of the discomfort experienced by patients. The investigators will study patients with chronic IBS-D who will receive 2 weeks treatment with the yeast or placebo followed by a 4 week gap and then a further 2 week treatment with placebo or the yeast, with the treatments allocated randomly. The investigators will also study 30 subjects who still have persistent loose bowel function 6 weeks after an infection with Campylobacter jejuni, one of the commonest causes of gastroenteritis in the UK. Subjects will be randomised to take either the yeast or placebo for 4 weeks . In both studies, the investigators will examine the effect of treatment on stool proteases, stool frequency and consistency and abdominal discomfort; the investigators will also take blood samples to examine some aspects of immune system function. The results of the study may suggest how yeast provides a benefit in patients with IBS and diarrhea and will provide data for a larger clinical trial.
TITLE A randomised placebo controlled trial to explore the effectiveness of Botulinum Toxin injection at reducing oral secretions and frequency of tracheal suctioning in tracheotomised patients. DESIGN Randomised controlled single blinded experimental design AIMS The purpose of this study is to determine if ultra-sounded guided injections of Botulinum Toxin into the salivary glands (Parotid and sub-mandibular glands) of patients with a tracheostomy tube in-situ assists in the reduction of oral secretions. OUTCOME MEASURES Amount of saliva production / frequency of tracheal suctioning / questionnaires. POPULATION In-patients at the Wellington Hospital based in London will be invited to participate within the study. Participants will be recruited from a range of wards which will include the Intensive Treatment Unit (ITU), acute medical wards and rehabilitation wards. All participants will have a tracheostomy tube in-situ and be breathing on room air, without the need for any mechanical ventilation. Participants will be receiving tracheal suctioning to assist in the clearance of saliva to maintain a clear airway. A total of 40 participants will be recruited to the study across a two year period. Each participant will have no prior history of the following: - swallowing disorders - stroke - myocardial infarction - head or neck surgery - respiratory disease - acute or progressive neurological disease - structural abnormalities that could affect swallowing - other medical conditions requiring medication that could affect swallowing. ELIGIBILITY Male and female adults over the age of 18 years TREATMENT Injection of Botulinum Toxin into both pairs of the parotid salivary glands and submandibular glands, using ultrasound guidance DURATION Data collection over a two year period / six weeks for each participant
