Brain MRI Longitudinal Volumetric Characteristics Associated With Outcomes of CASPR2-Limbic Encephalitis
Anti-CASPR2 limbic encephalitis (CASPR2-LE) is a rare neurological disorder primarily affecting males over the age of 50. It is mediated by an autoimmune antibody response in the central nervous system (CNS) against the cellular adhesion molecule contactin-associated protein-like 2 (CASPR2). This protein plays an important role in the trafficking of …
Usability and Clinical Effectiveness of an Interpretable Deep Learning Framework for Post-Hepatectomy Liver Failure Prediction
The goal of this in-silico clinical trial is to learn about the usability and clinical effectiveness of an interpretable deep learning framework (VAE-MLP) using counterfactual explanations and layerwise relevance propagation for prediction of post-hepatectomy liver failure (PHLF) in patients with hepatocellular carcinoma (HCC). The main questions it aims to answer …
Cardiovascular Risk Assessment For Kidney Transplantation - Utility of Computed Tomography Coronary Angiography in the Assessment of Patients Awaiting Kidney Transplantation
Cardiovascular disease (for example, heart attack, stroke, heart failure) is the commonest complication of kidney failure. Kidney transplantation reduces cardiovascular risk but cardiovascular disease remains the commonest cause of death in patients following transplantation. Current strategies to assess patient's cardiovascular risk prior to kidney transplantation do not identify those at …
Gut Microbiota in Patients With Limb Lymphedema and Recurrent Lymphangitis
Lymphedema is a chronic and progressive disease of the lymphatic vessels which affects about 300 million people worldwide. Patients may experience recurrent soft tissue infection of the limb affected by lymphedema, in terms of erysipelas, lymphangitis or cellulitis. No previous study has ever investigated the possible role of the gut …
Perfusion Index in Assessment of Postoperative Pain in Children.
The aim of this study will be to examine the validity of perfusion index in predicting pain and evaluation of its severity in the postoperative period.
Benzodiazepine Impact on Cognitive Function: fNIRs and PET/MRI Study
This study explores the impact of long-term benzodiazepine (BZDs) use on cognitive function and associated neuroimaging markers. While BZDs are established treatments for conditions like anxiety and insomnia, recent warnings highlight risks, including neurocognitive effects. Neuroimaging studies indicate potential neuroprotective effects of BZDs. Functional near-infrared spectroscopy (fNIRS) measures cerebral cortex …
SYSTEMS-LEVEL ANALYSES OF IMMUNE DYSREGULATION
The aim of the SAID study is to create a national resource in Sweden to enable comprehensive immunological analyses of an extremely complex and clinically challenging group of individuals with variable forms of immune system dysregulation. We hope to establish a biobank of primarily blood and fecal samples from children …
Difference Between Pressing and Vacuum Techniques in Fabrication of Orthodontic Aligners in Cases With Crowding: A Cross-sectional Study
This cross sectional study is aiming to compare 2 methods of clear aligner fabrication.
Diet-Induced Changes in GEnetic Material
This is a pilot study in 10 men to test the hypothesis that perturbations in substrate flux and the circulating metabolic and pro-inflammatory milieus during a high-fat diet paradigm will modulate DNA methylation of genes in sperm associated with obesity and cardiometabolic dysfunction.
Relationship Between Coronary Microvascular Dysfunction and Improvement of Left Ventricular Systolic Function in Patients With Heart Failure With Reduced Ejection Fraction Caused by Non-ischemic Etiology
This study aims to evaluate the incidence of coronary microvascular dysfunction (CMD) and its prognostic implication for the improvement of left ventricular function in patients who have been diagnosed with heart failure with reduced ejection fraction (HFrEF) caused by non-ischemic etiology.
