Exploring Skin Barrier Function, Recurrence of Diabetes Device-Related Contact Dermatitis, and Evaluation of Hydrocolloid and Silicone-Based Patches for Its Prevention in Children and Adolescents With Type 1 Diabetes

The goal of this clinical trial is to ensure that contact dermatitis does not prevent any person with diabetes from accessing optimal diabetes treatment. The main questions this study aims to answer are: How many pediatric patients with diabetes device-related contact dermatitis experience recurrence of contact dermatitis depending on the type of patch used underneath their device? Is one type of patch (silicone-based or hydrocolloid) more effective than the other at preventing contact dermatitis? The study population consists of children and adolescents aged 2-18 years with contact dermatitis (CD) caused by either an insulin pump or a continuous glucose monitor (CGM). Participants will be asked to complete questionnaires about their well-being and attend three in-person study visits. During these visits, the following assessments will be performed: Clinical skin examination Skin photographs of the most recently used insulin pump site, CGM site, and any reported skin reactions Measurement of height and weight Blood sample for measurement of long-term blood glucose (HbA1c) and filaggrin gene mutations Interview about skin reactions and related symptoms Skin ultrasound Tape stripping of the skin Electrical impedance spectroscopy (EIS), a non-invasive technique that transmits a harmless electrical signal through the skin

Sarcoma and Intra-infusion Exercise for Better Outcomes

The main goal of this clinical trial is to determine: 1) the safety and 2) feasibility of moderate-intensity, intra-infusion aerobic exercise in people receiving chemotherapy for non-resected sarcoma and 3) assess whether intra-infusion exercise acutely increases tumor perfusion. The trial aims to answer the following research questions: * Is intra-infusion aerobic exercise safe in people receiving chemotherapy for sarcoma? * Is intra-infusion aerobic exercise feasible in people receiving chemotherapy for sarcoma? * Does aerobic exercise induce acute increases in tumor perfusion? * In future work, which patient reported outcomes are relevant to explore in people receiving chemotherapy for sarcoma? Adverse event data and patient-reported quality-of-life outcomes will be compared to those of a historical control comprising patients who received chemotherapy for sarcoma within three years prior to study initiation. Participants will: * Participate in light- to moderate-intensity aerobic exercise during chemotherapy infusion (intra-infusion exercise) for the duration of their treatment protocol. * Exercise will follow a 15-minute exercise / 15-minute rest interval, totaling 30 minutes of exercise per hour of infusion. * Prior to initiating chemotherapy, undergo a single 15-minute exercise session. During peak exercise, a radioactive tracer will be injected intravenously followed by a single-photon emission computed tomography and computed tomography (SPECT /CT) scan to obtain images of tumor perfusion. A resting SPECT/CT scan will also be performed.

Colorectal Omics and ofCS Proteoglycans (COCO) in Screening and a Diagnostic Pathway

Colorectal Cancer (CRC), or bowel cancer, is a serious disease that affects many people globally. The earlier CRC is diagnosed, the better the patient outcomes. The problem with the current diagnostic methods is that they lead to many unnecessary endoscopies (colonoscopies). In Denmark alone, over 30,000 patients every year undergo a colonoscopy without having a serious disease. This puts a major strain on both patients and the healthcare system. This research project aims to solve that problem. COCO-S is investigating oncofoetal chondroitin sulphate-modified proteoglycans (ofCS) to see if ofCS can be used as a novel, unique cancer marker found in the blood. ofCS are special molecules that reappear in most tumour tissues. A method has been developed to detect ofCSs in a simple blood sample. Initial findings from an ongoing study are highly promising. A test using five different ofCS markers has shown very high accuracy in detecting CRC: it correctly identifies 86% of cancer cases (sensitivity) and correctly gives a "negative" result in 97% of cases without cancer (specificity). The results also suggest that high ofCS levels might help clinicians detect adenomas (polyps), which are early precursors to cancer. Combining the analysis of ofCS in the blood with the existing stool test (FIT) and other promising blood markers can significantly improve patient selection for a colonoscopy. This project will collect blood samples from patients scheduled for a colonoscopy. The blood will be analysed for ofCS and other substances to determine the combined predictive value for patients who truly require the procedure. The findings from this project could revolutionize CRC diagnosis. By more accurately identifying patients who need a colonoscopy, the number of unnecessary, invasive procedures can be reduced while maintaining patient safety and ensuring cancer is found in time.

REdo Transcatheter Aortic VALVE Implantation for the Management of Transcatheter Aortic Valve Failure

Transcatheter aortic valve implantation (TAVI) is a key-hole technique to replace an aortic heart valve that is narrowed and/or leaking. Although TAVI is a safe and effective treatment for a faulty aortic heart valve, the new TAVI valve will not last forever. Because it is a 'tissue' valve (made from the lining of a cow or pig heart), the valve will fail after a period of time as the tissue degenerates. When the TAVI valve fails, a viable treatment option is to perform a 'Redo TAVI' procedure, implanting a second TAVI valve inside the first failing valve. The main purpose of this study is to carefully evaluate patients being treated by Redo TAVI in order to document the short-term and long-term outcomes of the procedure. The study will also obtain information about which factors predict those outcomes. The study will also assess outcomes in patients who present with TAVI valve failure but are not suitable for Redo TAVI, and instead are treated either by open-heart surgery and surgical aortic valve replacement, or by medical therapy (medication). The study will provide doctors the information they need to understand the best way to treat patients who present with TAVI valve failure, and in particular how to perform Redo TAVI procedures with the best possible outcomes for patients.

MagnetisMM-32: A Study to Learn About the Study Medicine Called Elranatamab in People With Multiple Myeloma (MM) That Has Come Back After Taking Other Treatments (Including Prior Treatment With an Anti-CD38 Antibody and Lenalidomide)

The purpose of this study is to learn about the study medicine called elranatamab.This study aims to compare elranatamab to other medicines for the treatment of MM (a type of cancer). This study is seeking participants who: * Are 18 years of age or older and have MM. * Have received treatments before for MM. * Have MM that has returned or not responded to their most recent treatment. Half of the participants will receive elranatamab. The other half of participants will receive a combination therapy selected by the study doctor. The selected combination therapy will include 2 to 3 different medicines commonly used to treat MM. Elranatamab will be given as a shot under the skin at the study clinic about once a week. This may change to a smaller number of shots later in the study. The medicines in the combination therapy will be taken by mouth (at home or at the study clinic) AND will be given either as: * a shot under the skin at the study clinic * through a needle in the vein at the study clinic The number of times these medicines will be taken depends on what combination therapy the study doctor selects. Participants may continue to receive elranatamab or a combination therapy until their MM is no longer responding. The study team will see how each participant is doing with the study treatment during regular visits at the study clinic. The study team will continue to follow-up with participants after study treatment with telephone contacts (or visits). The study will compare the experiences of people receiving elranatamab to those people receiving a combination therapy. This will help learn about the safety and how effective elranatamab is.
