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 evaluate the prevalence of 4 or more DNA-repair gene defects in a population of men with metastatic Prostate Cancer (PC) and to use the reported DNA-repair gene defects to assess biomarker eligibility for niraparib interventional studies.
Vegetarian diets are commonly associated with lower blood pressure levels. This has been related to greater consumption of inorganic nitrate, since vegetables are the main source of this anion. Dietary nitrate is reduced to nitrite by commensal bacteria in the mouth, which in turn leads to increased circulatory nitrite availability. Nitrite can form nitric oxide by several pathways promoting a reduction in the vascular tone and lower blood pressure.
This is a 2-Part, 8-Visit, single-center, open-label, bilateral and dispensing clinical study. In Part 1 (Visits 1-4) all subjects will be Test Lens 1, in Part 2 (Visits 1-4) eligible subjects will be dispensed Test Lens 2 based on their responses to the CLDEQ-8 questionnaire. Subjects scoring between 11 and 19 on the CLDEQ will not continue into Part 2
There is a need to know more about the safety of mobilizing intensive care unit (ICU) patients who are receiving vasoactive drugs that support the heart and blood pressure. But before this research can be done, several uncertainties need to be addressed. To answer these uncertainties, the investigators will ask ICU patients receiving vasoactive drugs to take part in a study in three main stages. Firstly ICU patients will be asked whether they would be happy to take part in a future research trial on the safety of mobilizing patients who are receiving vasoactive drugs. Secondly, data will be collected about the current mobilization on vasoactive drugs that occurs. Finally, the investigators will try to follow up these patients 60 days after they start the study, to carry out some questionnaires and a walking test with the patients. These tests may be used in future research to measure the effect of mobilizing patients on vasoactive drugs.
The purpose of the study is to investigate the degree of improvement in appearance after treatment with different hyaluronic acid (HA) fillers. Product selection is based on Investigator assessment of participant tissue coverage and main treatment goal (volumizing, lifting or contouring).
Heart attacks are usually caused by clots in a coronary artery, depriving the heart muscle of blood. Platelets are the main type of blood cell causing clots to form and physicians typically give a combination of two anti-platelet drugs, aspirin and ticagrelor, to treat this. However, aspirin and ticagrelor have effects not just on the platelets but also on the immune system. The investigator has been investigating the effects of different doses of aspirin in heart attack participants when taken alongside ticagrelor, and have found that a new, lower dose of aspirin given twice daily, rather than the usual standard dose once daily, reduces the tendency to bleed whilst on treatment. The investigators are hoping to study the wider effects of different aspirin doses, with and without ticagrelor, and have therefore developed this study. During the two periods of the study, the investigator will give healthy volunteers a combinations of these medications and then stimulate their immune system, in order to see if the medications affect the immune response. The study will involve a period of medication for 10-14 days followed by a day in hospital stimulating the immune system with an injection into the bloodstream of a substance known as endotoxin, which causes temporary flu-like symptoms, followed by blood and urine tests. The investigator will then repeat the process, after a minimum of five weeks, taking a different medication combination and having a further endotoxin injection. The investigator will also keep in contact by telephone until 2 weeks after the end of the medication to ensure participant remain well.
To evaluate long-term BOS-free survival outcomes of the OCS™ Lung INSPIRE Trial patients.
This is a limited two centre randomized controlled feasibility trial towards a larger definitive trial designed to assess whether bed side ultrasound can reduce the rate of surgical fixation following emergency department manipulation of Colles' type wrist fractures. UDiReCT will mirror the proposed design of the definitive trial but will report feasibility data such as recruitment rate, data completeness and reliability of potential definitive trial outcome measures.
Following the establishment of causal links between breakfast consumption, the individual components of energy balance, and health it is now important to examine and target the underlying biological mechanisms involved to maximise potential health benefits. To begin investigating the outlined mechanisms healthy, non-obese participants will be recruited to take part in phase I (acute crossover design) of a wider project.
The present study will investigate the impact of altered substrate availability on muscle atrophy, insulin sensitivity and muscle protein synthesis following short-term forearm immobilization
