NCT ID: NCT05665621 Recruiting - Obesity, Childhood Clinical Trials

The Effects of Strength and Balance Training on Physical Function in Overweight Children

Start date: March 13, 2023
Phase: N/A
Study type: Interventional

This intervention study aims to examine the efficacy of a school-based exercise programme to improve strength and balance in overweight and obese 7-11-year-olds in the United Kingdom. The main question[s] it aims to answer are: - Is the school-based exercise programme effective in improving lower limb muscular strength and balance control? - How do increases in strength and balance skills impact physical function, the risk to musculoskeletal health, and physical activity? Participants will attend baseline, post-intervention, and follow-up testing that includes assessment of strength, balance, 3D gait, plantar pressure, physical function and physical activity. The intervention group will take part in physical activity sessions in their school for 1 hour twice a week for a total of 8 weeks. Researchers will compare the intervention group to a control group that will take part in no-activity sessions and carry out their normal school and seasonal activities.

NCT ID: NCT05665595 Active, not recruiting - Melanoma Clinical Trials

A Study of Adjuvant Pembrolizumab/Vibostolimab (MK-7684A) Versus Pembrolizumab for Resected High-Risk Melanoma in Participants With High-Risk Stage II-IV Melanoma (MK-7684A-010/KEYVIBE-010)

NCT ID: NCT05665166 Recruiting - Clinical trials for Mucopolysaccharidosis II

Autologous Ex-vivo Gene Modified HSCT in MPSII

Start date: June 1, 2023
Phase: Phase 1/Phase 2
Study type: Interventional

Patients with MPS II have a clinical disorder marked by progressive brain disease, neurological and somatic symptoms due to the accumulation of undigested glycosaminoglycans in all cells of the body. This study will be the first in human clinical trial to explore the safety, tolerability and clinical efficacy of ex vivo gene therapy (autologous CD34+ cells transduced with a lentiviral vector containing the human IDS gene) in MPSII patients. Following treatment with the gene therapy patients will be followed up for a minimum of 2 years.

NCT ID: NCT05665127 Recruiting - Clinical trials for Acute Coronary Syndrome

Point of Care Evaluation of High-sensitivity Cardiac Troponin

POC-ET
Start date: November 16, 2022
Phase:
Study type: Observational

In this observational research project the investigators wish to test new technologies that could allow them to either detect or rule out heart attacks earlier. Currently, when a patient attends the Emergency Department with symptoms that could be due to a heart attack, the patient has a blood test taken from a vein in the arm. This is sent to a laboratory to measure the level of a protein called troponin that is released from the heart when it is damaged. Doctors and nurses use the level of troponin measured in that blood sample, along with a tracing of the heart and an assessment of symptoms, to decide whether the patient is having a heart attack. On average, it takes about 2 hours from the patient arriving at hospital to the doctor or nurse receiving the blood test result so they can make this diagnosis. A device has been designed that can measure troponin by using a drop of blood from a finger prick with the result available in around 10 minutes. This means that if a patient is having a heart attack we can diagnose it earlier and give them treatment. Previous studies have also showed that the majority of patients who attend hospital with chest pain ultimately do not have a heart attack. With this new device the investigators hope to be able to reassure these patients that their symptoms are not due to a heart attack, so the clinical team can concentrate on finding out what else could be causing their chest pain, and ultimately discharge them earlier. The investigators aim to find the best way to use this new device and look at the impact this device has on the length of time from sample to diagnosis and time spent in hospital.

NCT ID: NCT05665036 Withdrawn - MPS I Clinical Trials

NCT ID: NCT05664438 Recruiting - Clinical trials for Spinal Cord Tumor of Cervical Spine

3T MRI of Intramedullary Spinal Cord Tumours

Start date: October 17, 2022
Phase:
Study type: Observational

Intramedullary spinal cord tumours (IMSCTs) are a type of tumour that arises from cells within the spinal cord. They are rare, accounting for around 4-10% of central nervous system tumours. They commonly present as back/neck pain and have poor outcomes if not treated. IMSCTs fall into various subtypes. Around 90% are either ependymomas or astrocytomas. Ependymomas are usually quite distinct from the surrounding tissue and therefore can often be treated successfully with surgery. In contrast, astrocytomas tend to invade the surrounding tissue and, as a result, generally cannot be entirely surgically removed. Radiotherapy is recommended instead of surgery for tumours that cannot be operated. Unfortunately, ependymomas and astrocytomas can appear very similar on diagnostic scans and are therefore difficult to tell apart before surgery. Biopsy therefore remains the current gold standard for tumour subtype differentiation. Any spinal cord surgery, whether it be biopsy or resection, poses major challenges due to the small size of the spinal cord. A small corridor via the back of the spinal cord, known as the posterior midline, usually offers the safest approach to a tumour. However, finding this access corridor can be very difficult because tumours tend to deform the anatomy of the spinal cord, leading to a high risk of injury to the normal spinal cord tissue or nerves. The primary objective of this pilot study is to test if cutting-edge spinal cord magnetic resonance imaging (MRI) techniques could help to better differentiate between tumour subtypes. The investigators will do this by comparing various imaging metrics between the tumour subtypes, confirmed by biopsy. The investigators' second objective is to see if these MRI techniques could help to identify, pre-surgery, the location of the posterior midline of the spinal cord. The investigators will do this by comparing the prediction of the midline location from imaging with blinded observations by the surgeon during planned surgery. Additionally, the investigators want to investigate the relationship between imaging metrics and patient pain and sensorimotor symptoms, to explore if imaging offers insight into the variety of clinical symptoms associated with these tumours. The investigators' hope is that the results of this study could inform a future larger trial that would be designed to fully assess the utility of cutting-edge MRI techniques for reducing both the need for spinal cord surgery and the risks associated with surgery in IMSCT patients.

NCT ID: NCT05663944 Active, not recruiting - Clinical trials for Advanced Chronic Liver Disease

REpurposing SirolimUS in Compensated Advanced Chronic Liver Disease. The RESUS Proof of Concept Study

RESUS
Start date: July 25, 2022
Phase: Phase 2
Study type: Interventional

Background: Advanced liver scarring leads to liver failure, liver cancer and premature death. It mainly affects people in the working age group (18-65 years) and is the only major cause of death that is still increasing every year in the UK. It costs the NHS £2.1 billion a year. This will continue to rise due to increasing alcohol misuse and the obesity crisis. Advanced liver scarring remains incurable as there is no treatment to slow progression of scarring. Sirolimus is a medication that has been used to prevent rejection after organ transplantation for over 20 years. It reduces liver scarring, improves liver functioning and prolongs life in animals. It has also been shown to reduce liver scarring in patients after liver transplantation. Sirolimus, therefore offers a potential treatment option for liver scarring. Question and Objectives: If used in patients with advanced liver scarring, can sirolimus slow the progression of scarring? The main objective is to undertake a small-scale study (proof of concept) to investigate if sirolimus could slow the progression of scarring in patients with advanced liver scarring using clinically relevant biomarkers, which will see if the liver responds to treatment. How it will be done: The study will be conducted in Nottingham University Hospitals NHS Trust. 45 patients with advanced liver scarring will be randomly given either sirolimus or placebo tablets daily for 6 months. Participants will have a liver biopsy and a MRI scan at the start and end of the study to measure the change in the biomarkers of liver scarring. A reduction in these markers will indicate successful treatment. Participants will be monitored for safety of the drug. Potential Impact: If found efficacious, sirolimus would provide an acceptable treatment for patients with advanced liver scarring and would also save a substantial sum of money for the NHS.

NCT ID: NCT05663788 Recruiting - Colorectal Cancer Clinical Trials

Web-based Learning Module on Optical Diagnosis of Early Colorectal Cancer

LODIP
Start date: July 1, 2022
Phase: N/A
Study type: Interventional

International guidelines recommend deciding the treatment of colorectal lesions based on the estimated histology by endoscopic optical diagnosis. However, the theoretical and practical knowledge on optical diagnosis is not widely expanded The mail goal of this randomised controlled trial is to compare the pooled sensitivity of optical diagnosis for predicting deep submucosal invasion in large non-pedunculated polyps > 20 mm assessed in routine colonoscopies of gastroenterologists attending a e-learning module (intervention group) vs gastroenterologists who do not (control group) The main questions the study aims to answer are: - Is the pooled sensitivity of optical diagnosis for predicting deep submucosal invasion in large non-pedunculated polyps assessed in routine colonoscopies increased in those gastroenterologists participating in the e-learning module? - Is the pooled diagnostic accuracy of optical diagnosis for predicting deep sm invasion in large non-pedunculated polyps ≥ 20 mm assessed in routine colonoscopies increased in those gastroenterologists participating in the e-learning module? - In lesions with submucosal invasion, is the en bloc and complete resection rate (R0) increased in those gastroenterologists participating in the e-learning module? - In lesions referred to surgery, is the pooled benign polyps rate decreased in those gastroenterologists participating in the e-learning module? - In lesions treated with advanced en bloc procedures (ESD, TAMIS, fullthickness resection), is the pooled rate of histology with high-grade dysplasia, intramucosal cancer or submucosal invasion increased in those gastroenterologists participating in the e-learning module? - In lesions treated with piecemeal endoscopic resection, is the pooled rate of histology with high-grade dysplasia, intramucosal cancer or submucosal invasion decreased in those gastroenterologists participating in the e-learning module? - Is the diagnostic accuracy for predicting deep submucosal invasion in a test with pictures increased after participating in the e-learning module? The participants (or subjects of study) are gastroenterologists. They will be randomised to do the e-learning course (intervention group) or not (control group). Researchers will compare clinical outcomes of gastroenterologists participating in the e-learning module vs gastroenterologists not participating in the e-learning module to see if: - the pooled sensitivity of optical diagnosis for predicting deep submucosal invasion in large non-pedunculated polyps > 20 mm assessed in routine colonoscopies is increased. - the pooled diagnostic accuracy of optical diagnosis for predicting deep sm invasion in large non-pedunculated polyps > 20 mm is increased. - the en bloc and complete resection rate (R0) is increased in lesions with submucosal invasion. - the pooled benign polyps rate decreased in lesions referred to surgery. - the pooled rate of histology with high-grade dysplasia, intramucosal cancer or submucosal invasion increased in lesions treated with advanced en bloc procedures (ESD, TAMIS, fullthickness resection). - the pooled rate of histology with high-grade dysplasia, intramucosal cancer or submucosal invasion decreased in lesions treated with piecemeal endoscopic resection. - the diagnostic accuracy for predicting deep submucosal invasion in a test with pictures after participating is increased.
