Imaging Biomarkers to Stratify the Risk of Barotrauma in ARDS
The high incidence of barotrauma in patients with COVID-19-related acute respiratory distress syndrome (ARDS) (16.1%, with a mortality rate >60%) provides rationale for considering COVID-19 ARDS a paradigm for lung frailty. The investigators recently discovered that the Macklin effect is an impressive radiological predictor of barotrauma in COVID-19 ARDS. Since …
Risk Prediction Model for Exacerbating Phenotype in Patients With Chronic Obstructive Pulmonary Disease
This study is planned to be conducted based on the cohort of patients with severe chronic obstructive pulmonary disease in our hospital. Based on gut microbiota, random forest was used to search for potential diagnostic biomarkers in patients with frequent acute exacerbation and controls with non frequent acute exacerbation; Construct …
Liquid Biopsy for Early DiagNosis of Squamous Cell Carcinoma of the HeAd and NeCk rEgion
The 5-year survival for Head and Neck squamous cell carcinoma (HNSCC) across all TNM stage groups is approximately 50%. Patients who are present with stage I & II disease have significantly better survival. When a patient presents to their general practitioner (GP) with symptoms suggestive of HNSCC, they may be …
Bespoke ctDNA Assay for Recurrence and Treatment Response Monitoring in Advanced Epithelial Ovarian Cancer
This prospective observational study is to assess the dynamics of circulating tumor DNA (ctDNA) in patients with advanced epithelial ovarian cancer (EOC) undergoing surgery, adjuvant chemotherapy, followed by poly adenosine diphosphate-ribose polymerase (PARP) inhibitors until disease progression or the end of the study. All patients will be closely monitored throughout …
Defining the Brain Phenotype of Children With Williams Syndrome
Background Little is known about how the brain changes during childhood and adolescence, how genes affect this process, or how the brains of people with 7q11.23 genetic variation change during this period. Researchers are interested in using magnetic resonance imaging to study how the brain changes in healthy children and …
Comparison of Computertomography Scan, Electrical Impedance Tomography, and Ultrasound of the Lung in Infants
The study focuses on regional lung examination, in particular on the differentiation between collapsed and hyperinflated lung areas. The purpose of the study is to elaborate common and discriminative elements between different lung imaging modalities in infants and to generate hypotheses for the bedside use of EIT and LUS in …
Ultra-hypofractionated Radiotherapy in Breast Cancer Patients
The present multicenter, retrospective and prospective observational study, aims to evaluate an ultra-hypofractionated whole breast irradiation schedule (WBI, 26 Gy in 5 fractions), in order to confirm literature data (FAST-F study) in the clinical practice. Patient population included women affected by early stage breast cancer (BC), both invasive and ductal …
REgistry of Pulmonary Arterial Hypertension Associated With CONNECTIVE Tissue Diseases (RECONNECTIVE)
The RECONNECTIVE Registry is an observational single center study, focused on the subgroup of precapillary pulmonary hypertension related to connective tissue diseases. All patients will have hemodynamic confirmation by right heart catheterization and will be follow-up for at least 5 years from admission. All patients diagnosed with Group I Pulmonary …
ACCESS Registry: A Post Market Follow-up Study to Monitor the Safety, Performance and Usability of Occlutech Accessory Medical Devices
The registry is an international, multicenter, non-randomized, non-invasive study to assess the safety, performance and usability of the Occlutech Accessories "Occlutech Delivery Set (ODS), Occlutech Pistol Pusher (OPP), Occlutech Occlusions-Pusher (OOP) and Occlutech Sizing Balloon (OSB)" used for implantation procedures (catheter-based interventions) of cardiac implants via completing surveys (questionnaires) for …
Developing Advanced Neuroimaging for Clinical Evaluation of Autoimmune Encephalitis
Autoimmune encephalitis is brain inflammation caused by the immune system mistakenly reacting against proteins in the brain. The commonest form is called NMDAR-antibody encephalitis (N-methyl-D-aspartate receptor antibody encephalitis), a rare condition which mainly affects children and young people and causes difficulties in memory, thinking and mental health which can have …
