Accurate classification of growths in the large bowel (polyps) identified during colonoscopy is imperative to inform the risk of colorectal cancer. Reliable identification of the cancer risk of individual polyps helps determine the best treatment option for the detected polyp and determine the appropriate interval requirements for future colonoscopy to check the site of removal and for further polyps elsewhere in the bowel. Current advanced endoscopic imaging techniques require specialist skills and expertise with an associated long learning curve and increased procedure time. It is for these reasons that despite being introduced in clinical practice, uptake of such techniques is limited and current methods of polyp risk stratification during colonoscopy without Artificial intelligence (AI) is suboptimal. Approximately 25% of bowel polyps that are removed by major surgery are analysed and later proved to be non-cancerous polyps that could have been removed via endoscopy thus avoiding anatomy altering surgery and the associated risks. With accurate polyp diagnosis and risk stratification in real time with AI, such polyps could have been removed non-surgically (endoscopically). Current Computer Assisted Diagnosis (CADx, a form of AI) platforms only differentiate between cancerous and non cancerous polyps which is of limited value in providing a personalised patient risk for colorectal cancer. The development of a multi-class algorithm is of greater complexity than a binary classification and requires larger training and validation datasets. A robust CADx algorithm should also involve global trainable data to minimise the introduction of bias. It is for these reasons that this is a planned international multicentre study. The Investigators aim to develop a novel AI five class pathology prediction risk prediction tool that provides reliable information to identify cancer risk independent of the endoscopists skill. These 5 categories are chosen because treatment options differ according to the polyp type and future check colonoscopy guidelines require these categories Read Less

In the proposed study, the investigators aim to test an AI-prototype which adaptively collects information about a patient's mental health symptoms at the time of referral in order to support and facilitate the clinical assessment. Read Less

Tacrolimus is a medicine given to try and stop rejection of a new kidney after transplant surgery. If too much taken the kidney may be damaged. If not enough taken, the risk of rejection is increased. Creatinine is a waste product made by the muscles and is normally removed from the body by the kidneys. If kidney function gets worse, the creatinine level in the blood goes up and means the new new kidney is not working properly. It is important to monitor levels of tacrolimus and creatinine regularly, to keep the kidney as healthy as possible. Regular monitoring also aids with balancing the amount of tacrolimus that patients need to take. The COVID-19 pandemic led to changes in the delivery of transplant services. One such changes was a move to the use of point-of-care, and at home devices. The study involves the set-up a new method in an NHS laboratory to test tacrolimus and creatinine levels in blood collected in the normal blood tubes and to compare the results with this new collection device, to see if the results are the same. If the results match, patients will continue to collect a blood sample using the new devices and send it to the laboratory. This will save both patients and the NHS time and money as they will not have to travel to a hospital to have their bloods taken. Read Less

The research question is: Can the research recommend better ways for social care and health services to work work together to help adoptive and foster families? Can a therapy called DDP improve the mental health of 5-12 year old fostered or adopted children? Is DDP worth the commitment families need to give to it - and the extra cost to the services that deliver it? More than half of adopted or fostered children in the UK have mental health problems including ADHD (i.e. hyperactivity, impulsive behaviour and poor concentration), antisocial behaviour and problems with relationships. Abused and neglected children are more likely than others to have problems in school, become homeless, get involved in crime and even die young (e.g. from suicide), yet there are no fully tested treatments for such complex mental health problems. This is a huge problem because early treatment could greatly improve children's life chances - and reduce strain on health and social care budgets. There is a Dyadic Developmental Psychotherapy (DDP) a parent-child therapy that takes around 20 sessions and focusses on "Playfulness, Acceptance, Curiosity and Empathy". There is not yet available really good evidence for or against it: many UK therapists like DDP, but it is a big commitment for families: once a week for about six months children will need time off school, the parents will need time off work - and this can be hard to explain to school friends, colleagues and bosses. Research team doesn't just need to know if DDP improves children's mental health - they also need to know if the commitment needed is worth it for families and whether the costs to services outweigh the benefits. In PHASE 1 the research team will find out whether DDP can work smoothly in the three different settings where it is usually delivered: the NHS, Social Care and Private Practice. Many abused children need other medical and psychiatric support so, the research will assess whether children can get any additional assessments or referrals they may need . In PHASE 2, the research team plans to find out if it is practically possible to run a high quality trial of DDP. This phase will involve 60 families to find out if they are happy to take part (whether offered DDP or usual services). If all goes to plan, these 60 families will contribute to the final results, along with the 180 families involved in the next PHASE 3 when the research team will test whether DDP is better than usual services and, if it is, whether the improvements in child mental health outweigh the costs. What impact will the research have? This study will make recommendations about how services should work together to help abused and neglected children and their families. If the researcher team finds that DDP is worth the time and money, it could improve the mental health of abused and neglected children across the world. Read Less

This is a multi-centre, non-randomised, open label Phase I clinical trial of an Advanced Therapy Investigational Medicinal Product (ATIMP) in adults (age ≥16) with (1) high risk, relapsed/refractory (r/r) CD19+ B-ALL; (2) r/r DLBCL; (3) r/r CLL/SLL and (4) r/r FL and (5) r/r MCL. The ATIMP for this study is cryopreserved autologous patient-derived T-cells transduced with the lentiviral pCCL.PGK.alpha.CD19CAT-41BBzeta vector, CD19CAT-41BBζ CAR T-cells (referred to subsequently as CD19CAR T-cells) which is classified as a gene therapy medicinal product. Patients will undergo an unstimulated leucapheresis for the generation of the ATIMP. The ATIMP will take approximately 15 days to generate. During this period, patients may receive "holding" chemotherapy as per institutional practice to maintain disease control. The study will evaluate ATIMP safety and efficacy and the duration of disease response in adults with high risk / relapsed CD19+ B-ALL, DLBCL, B-CLL/SLL, FL and MCL. Recruitment into the ALL cohort has been completed and no further patients with ALL are being treated on the study. Patients receive pre-conditioning lymphodepleting chemotherapy with cyclophosphamide 60mg/kg on Day -6 and fludarabine 30mg/m2 administered over 3 days (Day -5 to Day -3). Patients with DLBCL only will also receive a single dose of pembrolizumab 200 mg at day -1. Patients recruited to ALLCAR19 are treated with different dosing schedules, depending on their underlying disease. Patients with B-ALL and B-CLL/SLL are considered at high risk of CLL/CRES so receive split dosing, with the second dose only given in the absence of severe toxicity 9 days later. CAR T-cell dosing in ALLCAR19 is flat i.e. not dependent on patient body weight or surface area. * Regimen A1: Patients with B-ALL with a baseline marrow blast% of ≤20% receive a split dose with a first dose of 100 x 10\^6 CD19 CAR T-cells and a possible second dose of 310 x 106 CAR T-cells * Regimen A2: Patients with B-ALL with a baseline marrow blast% of \>20% receive a split dose with a first dose of 10 x 10\^6 CD19CAR T-cells and a possible second dose of 400 x 10\^6 CAR T-cells * Regimen B: Patients with DLBCL receive a single dose of 200 x 10\^6 CAR T-cells * Regimen C: Patients with CLL/SLL will receive a split dose with a first dose of 30 x 106 CD19 CAR T-cells and a possible second dose of 200 x 10\^6 CD19 CAR T-cells. * Regimen D: Patients with FL and MCL receive a single dose of 200 x 10\^6 CAR T-cells The study evaluates ATIMP feasibility and safety of generating CD19CAR T-cells and for B-ALL patients only, efficacy and the duration of disease response to CD19CAR T-cells. After completing the interventional phase of the study all patients, irrespective of whether they progressed or responded to treatment, enter long term follow up until 10 years post-CD19CAR T-cell infusion.

White adipose tissue (WAT) and brown adipose tissue (BAT) form the main adipose tissue subtypes in humans and several animals. BAT, owing to its unique metabolic function, has been of increased focus and interest in metabolic research (1). BAT forms the major organ of non-shivering thermogenesis in the body, and is dependent on the large concentration of mitochondria and increased uncoupling protein-1 (UCP-1) activity present in this type of tissue (2). There are numerous triggers for the metabolic activation of BAT including cold temperature, low body mass index (BMI), adrenergic agonists, and elevated concentration of thyroid hormones (3). BAT is found more abundantly in fetuses and infants, with significant regression into adulthood. The main areas where BAT can be found are the neck, mediastinum, axilla, retroperitoneum, and abdominal wall (4). Clinical research suggests that activation and thermogenesis in BAT are mediated by noradrenaline release from the sympathetic nervous system (5). With the increasing use of fluorodeoxyglucose positron emission tomography (18FDG-PET) imaging, there has been an increased detection rate of activated brown adipose tissue (aBAT); this may affect diagnoses and lead to false-positive reporting (6). Phaeochromocytomas/paragangliomas (PPGLs) are chromaffin-cell-derived endocrine tumors that emerge from the adrenal medulla or extra-adrenal ganglia. High FDG accumulation has been commonly noted in aBAT in patients with catecholamine-producing tumours, with subsequent resolution of these findings after resection of the tumour (7). This finding is likely related to the increased glucose transport related to noradrenaline excess (4). BAT has traditionally been considered to mainly express β3-adrenoreceptors; however, in vitro studies have indicated that activated β2-adrenoreceptors may be the main driving force behind thermogenesis (8). Studies reviewing PPGLs have shown an aBAT detection rate of 7.8% to 42.8% on FDG-PET imaging, correlating with elevated catecholamine levels but without clear correlation to germline mutations (9-12). In one study, this imaging finding was associated with a statistically significant reduction in overall survival (12). Standardisation for the 'standardised uptake value' (SUV) cut-offs for aBAT on FDG-PET are lacking, but these are often reported between 1.0 and 2.0 (13); in previous studies of PPGL, a cut-off value of \>1.5 has been employed (10, 12). Research on the clinical implications of aBAT in patients with PPGL remains scarce. The main objectives of this study were to gain further insights into BAT activation rates in patients with PPGLs and how this may relate to patient demographics, biochemistry, radiological features, mutational status, and outcomes. The main hypotheses were that aBAT rates would be significantly linked to the severity of catecholamine excess and could be considered a poor prognostic feature. Read Less

This purpose of this database is to collect, store and use appropriately derived data from routine patient care in a specialist dental practice. Comprehensive observational data will be gathered, systematically organised and be continuously updated. This data will be used to evaluate treatment outcomes and identify areas for improvement. This will contribute to the existing evidence base to validate new and current clinical concepts in dentistry. Patient consent will be sought for this, and all data extracted from patient notes will be stored and used anonymously. Use of the Oral Health Impact Profile (OHIP) -14 questionnaire pre and post treatment will be used to assess patient satisfaction with outcomes. Read Less

Multiple sclerosis (MS) is a chronic, inflammatory disease of the central nervous system. Lack of physical activity is common in people with MS (pwMS). This can lead to several comorbid conditions such as obesity, metabolic syndrome, osteoporosis, hypertension, diabetes and worse prognosis. An increasing number of studies suggest that physical exercise can play an important role in managing symptoms, preventing complications and comorbidities in pwMS, and may possibly be neuroprotective. However, doing exercise can be very challenging for pwMS who have moderate/severe mobility disability and who have problems with walking. In this project, the investigators will explore the use of a powered Exoskeleton as an exercise tool for people with moderate to severe difficulty walking due to MS. Powered Exoskeletons are wearable robots that offer opportunity to persons with lower limb weakness to stand and walk. The Exoskeleton-assisted training provides active training with potentially much less intervention needed from therapists. However, it is not clear whether pwMS can walk with a powered Exoskeleton at speeds and intensities sufficient to positively affect health and fitness outcomes. Thus, in this study, the investigators aim to explore whether using an Exoskeleton will enable people with MS to exercise at a moderate intensity and whether people with MS find this acceptable and safe to do on a regular basis. The investigators will also explore whether training with an Exoskeleton can improve walking. The investigators will train 12 patients with MS to walk with an Exoskeleton twice a week for 8 weeks. The investigators will compare the effects with another group of 12 patients who will do exercises with a fitness instructor twice a week for 8 weeks. The investigators will study whether walking with Exoskeleton is better than fitness training in terms of fitness outcomes, walking and cognitive, psychological factors. Read Less
