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.
Multi-centre Retrospective Observational Cohort study of patients who underwent pancreaticoduodenectomy from 01/01/2005 to 01/02/2022 with histologically confirmed pancreatic head malignancy
Skeletal muscle accounts for approximately 45-55% of total body mass in healthy adults and plays a pivotal role in whole-body metabolic health, locomotion and physical independence. Undesirable loss of skeletal muscle mass (atrophy) is, however, a common feature of many diseases and scenarios including ageing, bed rest/immobilisation, cancer and physical inactivity. Despite the exact mechanisms causing muscle atrophy being not yet fully understood, "anabolic resistance" (reduced muscle building in response to protein feeding and exercise) is thought to be key, especially for age-related skeletal muscle losses (known as sarcopenia). As such, the search for optimal strategies (e.g., exercise and/ or nutritional interventions) to combat this anabolic blunting remains a hot-topic in scientific research. Leucine, an essential and branched chain amino acid (EAA/BCAA), is thought to be the most potent AA for stimulating muscle protein synthesis (MPS; the muscle building process). Although, as a stand-alone supplement, leucine is unlikely to provoke a robust and prolonged state of MPS, low doses of leucine-enriched mixed-EAAs can elicit similar increases in MPS as compared to a large dose of whey protein. As reduced appetite and increased satiety (feeling fuller) are common with advancing age, supplementation of a low-dose protein (i.e., leucine-enriched) that can adequately stimulate MPS may contribute to muscle health maintenance in older adults and reduce satiation following a meal. This study aims to examine which of three doses of a novel leucine-enriched whey protein ("super-whey") best stimulates muscle building in older adults
Long-term pain affects one-third of the United Kingdom population and can be very disabling. People experiencing long-term pain often suffer from disturbed sleep because of their pain symptoms, and disturbed sleep can then make their pain symptoms worse. Managing long-term pain is also very costly to the National Health Service. The most common treatment is prescribed medicines, but these do not always work and can have serious side-effects for some patients. The investigators have been developing an alternative approach for treating long-term pain. This approach uses simple non-invasive tools to promote some kinds of brain activity over others. It involves patients using headphones to listen to some specific sounds, or a headset with lights flashing at particular frequencies. The studies undertaken so far seem to show that doing this can change how the brain responds to pain. It potentially offers an inexpensive yet effective way of reducing pain and improving sleep for patients with long-term pain. There are a few small studies that support this approach and more work is needed. In a recent study the investigators found that these tools can be reliably used in home settings and there were some indications that they improved symptoms. However, sleep was only measured with sleep diary and movement detection, there was no direct measurement of whether the stimulation frequencies were resulting in the desired brainwave changes. Finally, the benefit to symptoms may have been the result of other factors, such as the passage of time or placebo effect. Therefore this study extends the experiment, adding more accurate sleep monitoring which includes monitoring electrical activity in the brain (EEG), as well as providing rhythmic and non-rhythmic stimulation in a randomised order. The aim is to further test the effect of these home-based tools with individuals with long-term pain, in a more rigorous way. Up to 30 participants with long-term pain and pain-related sleep disturbance will use the tools for 30 minutes at bed time every day for 4 weeks (2 weeks with one type of stimulation, 2 weeks with another type). The changes in participants' pain, sleep, brainwave frequencies, fatigue and mood will be measured. These findings will inform the planning and design of a future much larger study to test this technology, if this is justified by the results.
Gut microbiota produce different metabolites within the human body, which include neurotransmitters. Animal studies have demonstrated a critical role for the gut microbiota in various aspects of brain and behavioural function, and a smaller number of studies in humans have shown differences of gut microbiota composition in psychiatric conditions. However, almost nothing is known about the impact of neurotransmitters produced by the gut microbiota on human brain and behaviour. The way in which differences in brain, behaviour and personality traits are associated with the gut microbiota, and how they are influenced by a probiotic will be explored, with a special focus on GABA (Gamma Amino Butyric Acid). Abnormalities of microbiota composition have been identified in metabolic disorders, such as inflammatory bowel disease and obesity, and psychiatric conditions, such as depression and anxiety. The aim of this intervention trial will be to answer the following fundamental questions: 1. Does the population of gut bacteria capable of producing GABA modulate brain-based measures of GABA? 2. Does the population of gut bacteria capable of producing GABA influence performance in behavioural tasks known to depend on GABA-ergic function? The impact of a GABA producing probiotic on the measures of GABA in the brain and serum, relevant metabolites in blood, faecal and urine samples and performance in GABA dependent behavioural tasks will be investigated in this trial.
This is a follow-up study of subjects who received NTLA-2001 in a previous clinical trial as an observational evaluation of the long-term effects of the investigational therapy.
This is an experimental medicine, single-centre, observational test-retest study to evaluate Filgotinib's mechanism of analgesic action in RA patients. The investigators hypothesize that Filgotinib's mechanism of analgesic action is determined by at least two factors. The first is related to those CNS sensitization pathways seen in fibromyalgia, specifically DMN-insula brain functional connectivity and insular glutamate. The second is related to peripheral inflammation, specifically joint synovitis, blood cytokines/chemokines and DAN-LIPL functional brain connectivity. The CNS sensitization pain pathways related to fibromyalgia are more quickly modified compared to those related to peripheral inflammation and help explain Filgotinib's rapid onset of effect.
This is a Phase 3, multi-center, randomized withdrawal study to evaluate the efficacy and durability of ampreloxetine in participants with MSA and symptomatic nOH after 20 weeks of treatment. This study includes 4 periods: Screening, open label, randomized withdrawal, and long-term treatment extension (LTE).
The goal of this clinical trial is to assess the efficacy, safety and tolerability of the combination of lasofoxifene and abemaciclib compared to fulvestrant and abemaciclib for the treatment of pre- and postmenopausal women and men who have previously received ribociclib or palbociclib-based treatment and have locally advanced or metastatic estrogen receptor positive (ER+)/human epidermal growth factor 2 negative (HER2-) breast cancer with an estrogen receptor 1 (ESR1) mutation. The main question the study aims to answer is: • To compare the efficacy of the combination of lasofoxifene and abemaciclib with that of fulvestrant and abemaciclib Participants will receive either receive 5 mg/d of oral lasofoxifene plus oral abemaciclib 150 mg twice a day or the combination of fulvestrant 500 mg intramuscular (IM) on Days 1, 15, and 29 and then once monthly thereafter plus oral abemaciclib 150 mg twice a day.
Ventricular tachycardia (VT) is an abnormal rhythm arising from the bottom chambers (ventricles) of the heart. The hearts of most patients who develop VT have been previously damaged by a myocardial infarction (heart attack) or other heart muscle diseases (cardiomyopathies). The damage produces scar or fatty deposits that conduct electrical impulses slowly allowing VT to occur. Recurrent episodes of VT can compromise heart function and increase mortality. VT is prevented by special drugs but these are not always effective and can have many side effects. Most patients with VT will also have a specialised device called an implantable defibrillator (ICD) implanted. The ICD treats VT by either stimulating the heart rapidly or delivering a shock to it. ICDs are very effective but the shocks are painful and have a big impact on quality of life. If VT occurs despite optimal drug treatment, patients undergo an invasive procedure called catheter ablation. Here, wires are passed into the heart from the blood vessels in the leg and the damaged heart muscle causing the VT is identified whilst the heart is in VT. An electrical current is passed down the wire making its tip heat up allowing discrete burns (ablation) to be placed inside the heart. The ablated heart muscle doesn't conduct electricity which stops the VT and prevents it recurring. Some patients are so frail that ablation cannot be performed safely. A recent clinical trial has shown that VT can be treated in such patients using radiotherapy, which is usually used to treat tumours with high energy radiation. This approach is non-invasive, painless and requires no sedation or anaesthesia. This study will test whether VT can be successfully treated using stereotactic ablative radiotherapy. This can deliver high dose radiotherapy very precisely, whilst minimising the risk of damage to healthy tissues.
