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 greatest challenge in our ageing society are cardiovascular diseases such as stroke, heart attack, peripheral artery disease of the legs with non-healing wounds (ulcers), or diabetes. Specific diets with high polyphenol content are associated with lower incidence of cardiovascular disease and can improve macrovascular function when consumed acutely and chronically. Which role the smallest blood vessels (microcirculation) play in this and if the microcirculation responds to therapies is not well understood. One reason for this is that no generally available medical instrument has the resolution to study the microcirculation. The recently developed optical coherence tomography angiography (OCTA), currently mainly used by eye doctors, is able to visualise the microcirculation. The current randomised controlled cross-over proof-of-concept study will test the acute effect of a cocoa flavanol intervention on cutaneous microvascular structure and function of hands and feet together with macrovascular function of upper and lower extremities in healthy and type 2 diabetes participants. It is the hypothesis that cocoa flavanol intervention as compared to placebo can acutely increase microvascular vasodilation and macrovascular endothelial function in arms and legs together with arterial stiffness in both healthy and type 2 diabetes participants.
The goals of this clinical study are to assess the safety, tolerability, blood levels, and disease impact of UPB-101 when given to adults with mild asthma. Eligible participant will be consecutively assigned to 1 of 3 to 5 planned treatment groups. Each treatment group will consist of 8 individuals, six of whom will receive active drug (UPB-101) and 2 who will be given placebo. Neither the study doctors nor the participants will know which participants were assigned to active study drug and which were assigned to placebo. The study will be performed at 3-4 experienced research sites in the United Kingdom.
The APPLE Study aims to understand if specific diet and lifestyle patterns are present in individuals with psoriasis and if these factors are correlated with psoriasis severity.
Very controlled dietary intervention studies support that individual polyphenol rich foods and isolated polyphenols can increase endothelial function and HDL cholesterol and decrease blood pressure, arterial stiffness, and LDL cholesterol even in healthy subjects. The intake of (-)-epicatechin, the major polyphenol in cocoa, was previously mechanistically linked with acute improvements in endothelial function and nitric oxide availability. A profound understanding of inter- and intra-individual variability of responses in real life are an important area of research in a world that aims at personalized nutrition and medicine. N-of-1 trials are a powerful tool allowing to study small effects even in fewer subjects and help account for intra-individual variations in responses. The overall aim of the present pilot study is to evaluate intra-and inter-individual variability of responses to cocoa flavanols in everyday life using the N-of-1 paradigm. In this pilot study, young healthy humans will monitor blood pressure, pulse wave velocity, heart rate, diet, and physical activity on 8 days using a personal and wearable devices. Each subject will undergo the 8 study days; 4 days with cocoa flavanol capsules (CF; containing 750 mg (1500 mg per day)) and 4 days with calorically matched placebo capsules (P; 0 mg cocoa flavanols) taken at the same time in the morning with breakfast and at night before going to bed. The subjects will be randomized to different treatment allocation sequences to allow blinding of volunteers and investigator; either CF-P-CF-P-CF-P-CF-P or P-CF-P-CF-P-CF-P-CF.
The main purpose of this study is to find out if scanning the foot using a 3D scanner influences the effectiveness of custom made insoles, compared to the more traditional approach of taking a foam-box impression cast of the foot. Both of these methods are currently used as standard care in the NHS Greater Glasgow and Clyde (GGC) Orthotic Department. In this study, insoles will be manufactured either from a direct 3D scan of the foot, or from a foam-box impression cast, and a series of questionnaires will be used to measure any changes in foot pain and foot function. The results from this study will be used to develop an information resource for both patients and Orthotists which will fill gaps in our current knowledge and hopefully guide us further in providing the best possible care for future patients who require insoles.
The study was planned in 2 parts: Parts A and B. In Part A, we tested 2 single doses of the study medicine in healthy volunteers: 500 mg and 750 mg. Part B was an optional part to test once-daily doses of the study medicine in healthy volunteers. We aimed to assess the safety, tolerability find out the side effects and blood levels of the PXL770.
This experimental proof-of-concept study in healthy volunteers investigates whether a specific form of self-relating, namely, self-compassion, can be controlled through non-invasive stimulation of the vagus nerve. The vagus nerve is part of the parasympathetic nervous system (the 'rest and digest' system) and its fibers are spread throughout the upper body, face, and neck, including a branch that innervates parts of the external ear (e.g. the tragus), close to the surface of the skin. This allows the 'auricular branch' of the vagus nerve to be readily stimulated electrically. Importantly, this can be achieved non-invasively using a transcutaneous vagus nerve stimulation (tVNS) device. The investigators will test the effects of tVNS alone and in combination with a meditation-like technique that is intended to increase participants' feelings of self-compassion (self-compassion imagery). In particular, the investigators will assess participants' experience of self-compassion and self-criticism, as well as other outcome measures, before and during stimulation, and again after they perform the self-compassionate imagery exercise. These effects will be compared to three other groups: one that receives tVNS along with a control (sham) imagery procedure, another that receives sham tVNS and self-compassion imagery, and a final group that receives sham tVNS and sham imagery. It is expected that the group that receives active tVNS and the self-compassion imagery exercise will experience the largest average increases in self-compassion and decreases in self-criticism. The findings of this study will help us better understand the role of the vagus nerve in complex cognitive-emotional experiences - like compassion - and may also motivate the development of bioelectronic stimulation methods that can be used alongside psychological techniques for improving self-compassion and reducing self-criticism, particularly among people with certain psychological disorders.
The purpose of this study is to determine recommended phase 2 dose(s) (RP2Ds) of JNJ-80038114 in Part 1 (dose escalation) and to determine the safety at the RP2D(s) in Part 2 (dose expansion).

As we age, muscles can become progressively weaker to the point that tasks of daily living cannot be carried out safely. However, regular resistance exercise training has been shown to maintain and even increase muscle strength in older adults. Previous research has identified a homebased, non-loaded, lower limb only, 'exercise snacking' model that does not require exercise equipment or supervision as a viable alternative exercise strategy to traditional resistance exercise, with potential to improve leg muscle strength in healthy older adults. This approach has been shown to be feasible and acceptable to general healthy older adult population, however this approach to exercise focussed on improving strength has not been considered in a clinical population. This research seeks to investigate the acceptability of 28 days of homebased exercise snacking in outpatients with attending the memory clinic at the Research Institute for Care of the Elderly (RICE) Centre in Bath, UK, with diagnosis limited to mild cognitive impairment only. This study will improve understanding of how zero-cost exercise strategies to potentially improve muscle function and delay frailty could be incorporated in daily routines of older adults.
