Does a Periaqueductal Gray-vagus Nerve Interface Malfunction Explain the Nat hx With Its Numerous Co-morbidities?
Postural tachycardia syndrome (POTS) is a common and disabling disorder among adolescents. No epidemiologic data exist to support the often cited 0.5 to 2% prevalence. Case series suggest 3 to 5 times greater incidence in girls than boys. POTS is defined in children as daily chronic symptoms of orthostatic intolerance …
Construction and Validation of a Predictive Model for the Efficacy of Different Biologics in Inflammatory Bowel Disease
Inflammatory bowel disease (IBD) is a group of chronic progressive gastrointestinal diseases that can recur throughout life and for which there is no cure. Biologics, the first line of treatment, are not only expensive, but also 30-50% of patients lack response to this type of drug therapy. However, there is …
A Clinical Study of Evaluating Myocardial Viability in Ischemic Heart Disease with Integrated 18F-FDG PET/MR
The main purpose is to evaluate the accuracy of myocardial imaging obtained through integrated 18F-FDG PET/MR in detecting viable myocardium. The secondary objective is to evaluate whether myocardial imaging obtained through integrated 18F-FDG PET/MR can replace 18F-FDG PET combined with 99mTc MIBI SPECT/CT gated myocardial perfusion imaging.
Hyperpolarized 13C Pyruvate-MRI and FDG-PET in a Single Exam for the Prognosis of Ischemic Cardiomyopathy
The goal of this clinical trial is to evaluate a novel imaging approach that combines hyperpolarized 13C pyruvate magnetic resonance imaging (HP-13C-MRI) and [¹⁸F]Fluorodeoxyglucose positron emission tomography (FDG-PET) in a single exam to improve the prognostic assessment of ischemic cardiomyopathy. The main questions this study aims to answer are: Primary …
Diagnostic Performance of Controlling Nutritional Status as a Nutritional Screening Tool in Patients With Inflammatory Bowel Disease
The objective of this observational study is to determine the diagnostic performance of CONUT as a nutritional screening tool in patients with Inflammatory Bowel Disease. The main questions to be answered are: What is the sensitivity and specificity of CONUT as a nutritional screening tool in patients with Inflammatory Bowel …
Inhaler Adherence and Inhalation Technique Assessed by a Smart Spacer in Patients with Severe Asthma on Biologics
Severe refractory asthma affects about 3.5% of asthma patients, often necessitating biologic therapy in addition to standard treatment. However, little is understood about maintenance and reliever inhalation medication adherence in these cases which might impact overall biologic response. Objectively monitoring inhalation medication adherence remains a significant challenge. The Smart AeroChamber® …
A Comparative Study Between Neutrophil/Lymphocyte Ratio and Lactate/Albumin Ratio as Predictive Inflammatory Markers for Sepsis
Aim of this study is to predict the prognostic values of Neutrophil/ Lymphocyte ratio and Lactate/Albumin ratio in the outcome of patients with sepsis and septic shock with lower respiratory tract infection, also to compare between them regarding sensitivity and specificity.
Exploratory Research on Constructing a Computational Biological Model Based on NGS for MRD After Breast Cancer Surgery
This study will include 80 subjects after radical breast cancer resection, collect blood samples of the above subjects, observe and quantify the characteristic changes of cfDNA in the blood of breast cancer subjects after surgery, and establish a computational biological model based on next generation sequencing to monitor breast cancer …
Development of a Clinical Screening, Diagnostic and Evaluation Tool for Patients With Lower Limb Lymphedema: Aim 4
Research investigating measurement properties for evaluating the decongestive treatment effect on different edema characteristics (e.g. water volume, hardness of the skin, water content,..) at the level of the lower limbs is missing. Information about the clinical relevant change criteria after treatment for nearly all these edema characteristics, is not present …
Changes in the Lipidomic, Immunological and miRNA Profile in Patients Undergoing a Dietary Program or Bariatric Surgery
Obesity is a chronic disease characterized phenotypically by an increase in body weight (BMI>30 kg/m2) and by a series of associated pathologies, such as hypertension, diabetes, hepatic steatosis. The association of these pathologies compromises the patient's survival and quality of life. The multifactorial origin of obesity makes its etiopathology difficult …
