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 C-MORE study is prospective observational holistic longitudinal study which will characterise the prevalence of multi-organ injury among COVID-19 survivors post hospital discharge and assess its effects on quality of life, exercise tolerance and mental health.
Dogs are some of nature's greatest detectives, owing to their incredible sense of smell and ability to be trained. Most of us will be familiar with seeing trained sniffer dogs at airports looking for drugs and other prohibited items, but their skills don't stop there. The use of medical detection dogs is becoming increasingly common, as they are able to identify cancers, changes in blood sugar levels and even predict seizures. These are just a few examples of dogs playing a key role in public health. Many diseases can alter the way humans smell. A study undertaken by the London School of Hygiene & Tropical Medicine (LSHTM) and Durham University has shown that dogs are able to accurately diagnose malaria. The investigators know that respiratory illnesses can alter your body odours, and thus the investigators plan to determine whether dogs are able to identify the novel coronavirus known as COVID-19 (or SARS-CoV-2). COVID-19 can present itself asymptomatically (i.e. causing no apparent symptoms), which could lead to the spread of infection in the population. The investigators believe that dogs may be able to identify asymptomatic patients, as well as those who have mild symptoms (symptoms not requiring treatment, hospital stay or limiting normal activities). It is thought that a single medical detection dog stationed within an airport would be able to screen up to 750 people for COVID-19 infection in just 1 hour, informing those who are infected to isolate, preventing further spread of the disease. In order to determine whether it is possible for dogs to accurately diagnose COVID-19, the investigators must first collect samples. NHS staff and members of their households that are eligible for SARS-CoV-2 screening, have been selected to participate in this study due to their potential exposure to this disease agent. In addition, participants from the general population who are displaying mild COVID-19 symptoms or have been exposed to COVID-19 will be recruited via hospitals, testing centers, outbreak testing programs and home testing programs. Initially, participants will attend their screening test as planned or confirm that they have had a swab test within the previous 24 hours. Immediately following this, the investigators will ask participants to collect samples of breath odour and body odour, which will be collected passively through the wearing of face masks, shirts, and nylon socks. The investigators will ask to be provided with the results of the SARS-CoV-2 screening swab, which will allow for us to determine whether participants are positive or negative for SARS-CoV-2. These odour samples will be grouped by positive or negative test results, and transported to LSHTM where these will be processed in order to prevent contact with the virus, negating the risk for dogs and their handlers. A pilot study will be undertaken to confirm whether dogs are able to distinguish between positive and negative samples using traditional sniffer dog training methods. If this is possible, the investigators will proceed to the main study to determine the accuracy (known as sensitivity and specificity) of the dogs' ability to identify the virus. Both the handler and the dogs themselves will be 'blinded' to the samples, and thus unaware of which sample is which. When the data generated by these tests is entered, it will be confirmed whether or not the samples have been correctly identified. The dogs will be trained to detect and report the detection of the volatile odours characteristic of COVID-19 infection. For quality control purposes the investigators also aim to characterise the COVID-19 odour profile by analysing samples with a special process called GC (gas chromatography) and/or GC-MS (gas chromatography coupled mass spectrometry). This will help to inform the identification of compounds showing differences between infected and non-infected samples. The investigators believe that this work could be useful in the fight against COVID-19.
This is a Phase 2, multicenter, open-label study to provide continued supply of parsaclisib as monotherapy or in combination therapy with itacitinib, ruxolitinib, or ibrutinib to participants from Incyte-sponsored studies of parsaclisib.
Preeclampsia is a multi-system vascular disease which affects 2-5% of pregnancies. It is also a risk factor for the development of cardiovascular disease later in life and a number of functional and structural cardiac changes have been found in this population of patients. In mouse models disruption of a group of immune cells, neutrophils, has led to alteration of the placenta and offspring consistent with those seen in preeclampsia. These mice also have an abnormal cardiac function and structure (Nadkarni et al 2016). The investigators hypothesis that this may also occur in humans. This study aims to intimately link the maternal immunological and vascular components of cardiac dysfunction in women preeclampsia. The investigators hypothesise that in preeclampsia activated neutrophils may affect maternal immune system thus leading to myocardial injury and altered cardiac function. The study intends to identify the mechanisms by which the maternal immune system (focusing on neutrophil and T-cell subsets) affects cardiac function in women with preeclampsia. Specific aims to be addressed are: Aim 1: To correlate specific neutrophil phenotype(s) and function to cardiac function in women with preeclampsia during pregnancy Aim 2: To test whether specific activated neutrophil phenotype persists postpartum and whether this neutrophil phenotype correlates with cardiac function in women with preeclampsia postpartum The study population will comprise of 3 groups: 1. Normotensive pregnant (~33 patients) 2. Pregnancy-induced hypertension (PIH; New-onset hypertension after 20 weeks without proteinuria; ~33 patients) 3. Preeclampsia (~34 patients) Cardiac function will be evaluated using cardiovascular magnetic resonance, echocardiography and cardiac markers in the blood. The participants immune system will be assessed from blood samples looking at the immune cells, hormone levels and inflammatory and non-inflammatory mediators. The secondary research objective is to investigate whether changes in the immune system and cardiac function in participants is persistent after delivery. Therefore participants will have scans and blood tests both antenatally and at 3 months postnatally. By identifying key changes in immune cell type and function with cardiac abnormalities in women with preeclampsia, data obtained from this study could provide novel insight into how the maternal immune system influences cardiac changes in normal and preeclamptic pregnancies. Identifying such links could pave the way for future therapeutic targets.
Exercise has been established to be safe and result in improved physical function and quality of life for most individuals with cancer. However, little information exists regarding whether exercise can increase overall survival and reduce disease progression, events related to cancer spreading to the bones (e.g. bone fracture, spinal cord compression, extra radiation or surgery), and pain in patients with metastatic prostate cancer that is no longer responding to hormone therapy. The primary objective of this study is to determine if high intensity aerobic and resistance training plus psychosocial support increases overall survival compared to psychosocial support alone in prostate cancer patients. The Movember foundation is providing support for the conduct of this study
This study aims to elucidate the pathophysiological mechanisms underlying the adverse effects associated with the use of long-acting beta-agonists (LABAs) in asthma. Participants with mild asthma will be enrolled into a single-arm, unblinded trial in which they receive 2 weeks of salmeterol xinafoate monotherapy, followed by a 2-week washout period, followed by 2 weeks of salmeterol xinafoate / fluticasone propionate combination therapy. The induction of asthma disease-relevant pro-inflammatory mediators in the airways will be measured at each stage and correlated with relevant clinical parameters.

This is database designed to explore clinical outcomes related to vascular assess in the population of Northern Ireland with CKD Stage 5 and End-stage Renal Failure.
Posterior fossa tumours (PFT) account for 2/3 of childhood brain cancers. They can be highly malignant requiring combined chemotherapy and radiotherapy post-surgery for a >50% chance of cure. PFT frequently involve the cerebellum which is responsible for coordinating movement, balance, emotional control, and links closely to control of affect and executive function. PFT survivors show highly variable profiles for cognitive and sensorimotor functioning which are influenced strongly by the severity of the pre-diagnostic or post-surgical brain injury State-of-the-art magnetic resonance imaging (MRI) scans can allow to measure a variety of different biological processes in the brain, and the investigators believe that some of these MRI measures (called MRI biomarkers) have the potential to improve our ability to understand and monitor consequences of the ablative brain surgery and complex mechanisms of motor skills recovery. Biomarkers are very important for the development of intervention because 1) they help understand the recuperation process and 2) they allow to effectively assess whether or not a treatment or intervention works. Transcranial magnetic stimulation (TMS) is a powerful non-invasive neuro-modulatory intervention that has the potential to evaluate the integrity of the nervous tracts from the brain to the hand. It is a procedure that applies magnetic pulses on the surface of the scalp to reach underlying brain tissue. TMS has built a reputable status among neuro-rehabilitative research, and there is currently a major effort to translate the positive research findings into clinically useful therapeutic strategies. This study is therefore an important first step towards understanding how potential MRI biomarkers and responses to TMS relate to motor symptoms in PFT young survivors. Once completed, this study will allow the investigators to select the most promising MRI biomarkers and TMS protocols to take forward into future treatment trials. The investigators aim to stimulate the recovery of coordination skills, help the development of targeted therapies, and consequently improve long-term quality of life in children and young people with history of brain tumour. The proposed research intends to prove the feasibility of such brain stimulation and imaging and collect some preliminary measures
End-stage renal disease typically requires haemodialysis to help replace kidney function. However, changes in oxygen uptake during haemodialysis have been linked to increased all-cause mortality. This complication of haemodialysis is linked to decreasing fluid volume, compromising blood flow to tissue and leukostasis within pulmonary tissue. However, an alternative cause of reduced oxygen availability (hypoxia) during haemodialysis is acute alkalosis. Alkalosis during haemodialysis can cause hypoxia via dysregulated ventilation and impaired ability for tissue to extract oxygen. Despite strong rationale for these mechanisms, few studies have fully explored causes of hypoxia during haemodialysis. Greater understanding may help to mitigate the risk associated with this vital treatment option. The study will comprise of end-stage renal disease patients who regularly undergo haemodialysis. Three blood samples will be attained before, during and after haemodialysis to assess arterial blood gases. In a small subset of patients, white blood cell (WBC) count and cardiac output will be assessed via a non-invasive cardiac output monitor during treatment. Regression analysis will be performed to help identify predictors of hypoxia during haemodialysis. Patient burden is negligible, with blood samples attained from the dialyser as part of routine treatment. In the patients who agree for cardiac output assessment, the patient will be required to have four small noninvasive sensor pads placed on the chest. Patients will be assessed over 3 consecutive treatments during a single week.
