BreathinG-induced Myocardial and Cerebral Perfusion in Anxiety Disorders
This study aims to view variations in MRI measurements of the heart and the brain in people with anxiety versus healthy volunteers. The MRI measurements used will be Oxygenation-Sensitive Cardiac MRI (OS-CMR), a recent type of MRI which is safe, fast, and non-invasive.
Multi-parametric Imaging in Personalized Radiotherapy
The study consists in the retrospective and prospective collection of imaging data (along with clinical information related to treatment) of skull-base chordoma patients treated with particle therapy, to derive imaging biomarkers which, integrated with advanced mathematical models, will allow predicting treatment outcome on a multi-scale basis.
Immune Signature Analysis of Disease Progression in Post Immunotherapy Lung Cancer Patients
The purpose of this study is to examine the association between ctDNA/immune biomarkers and disease progression in patients who, at immunotherapy discontinuation, have completed at least 20 of an anticipated 24 months of pembrolizumab monotherapy or pembrolizumab-combination chemotherapy for mNSCLC.
Electrophysiology of Fetal Arrhythmia
Fetal research and clinical practice has been hampered by a lack of suitable investigational techniques. Currently, ultrasound is the only widely used method of studying fetal anatomy and physiology, but it has significant limitations for assessment of cardiac rhythm. The proposed study will allow the investigators to evaluate fetal magnetocardiography …
Neuroimaging and Neuropsychological Outcomes in Urea Cycle Disorders
In proximal urea cycle disorders (UCD), particularly ornithine transcarbamylase deficiency (OTCD), hyperammonemia (HA) causes increased brain glutamine (Gln) which perturbation is thought to be at the core of the neurological injury. In contrast, in distal UCD such as citrullinemia (argininosuccinate synthetase deficiency; (ASSD) and argininosuccinic aciduria (argininosuccinate lyase deficiency); (ASLD) …
Screening of Malignant Hyperthermia Susceptible Individuals
This study intends to target patients who underwent surgery under general anesthesia during the study period and developed malignant hyperthermia during or after surgery. Therefore, the total sample size was estimated to be about 50 people based on the past incidence of this rare disease. Every year, about 20 patients …
Endoscopic Treatment for Zenker's Diverticulum
Zenker's diverticulum (ZD) is a rare benign condition, due to an acquired sac-like outpouching of the mucosa and submucosa layers originating from the pharyngoesophageal junction. Endoscopic techniques like flexible endoscopic septum division (FESD) or per-oral endoscopic septotomy (POES), represent a minimally invasive alternative to surgery or to rigid endoscopic procedure …
Observational Study of Exposure to Environmental Toxicants Among Firefighters
Observational, within subject study design with 1 pre and 2 post-fire exposure biomarker samples collected to assess exposure to toxicants from combustion emissions related to fighting a structural fire.
Self Reported Pain in Women While Undergoing Treatment for Non-metastatic Breast Cancer
The overall purpose of this study is to investigate whether younger subjects report pain with pegfilgrastim (or biosimilar substitution) more often and/or at higher levels (greater intensity) than older subjects.This study will be carried out throughout the course of your chemotherapy treatment, which will be prescribed by your study doctor. …
Understanding immunE-related toXicities by multifACeT Profiling
A prospective observational cohort study of patients undergoing CPI therapy in which translational research is the fundamental aspect of the study.
