The Measurement of Chemicals in Exhaled Breath Can Identify If a Person is Infected with COVID-19
The type and number of chemicals in exhaled breath are different in people with infection as compared to those without infection. In this study, the breath of people with and without COVID infection will be measured. Changes in the amount and type of chemicals in breath will be used to …
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 …
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.
Urine Incontinence Occurrence and Sexual Hormones in Women With Chronic Spinal Cord Injury/Disease - a Pilot Study
There is a knowledge gap about the influence of the menstrual cycle on bladder function in women with spinal cord injury. So far, studies regarding urinary incontinence have primarily focused on women after menopause. It has become clear that a lack of the sex hormone estrogen, which occurs after menopause, …
Evaluation of the Effect of Adenoid Hypertrophy on the Masseter Muscle in Children: A Comparative Ultrasonographic Study
The goal of this observational study is to evaluate the effect of adenoid hypertrophy on the masseter muscle in children aged 3 to 8 years. The primary objectives are: To assess whether adenoid hypertrophy affects the thickness or structure of the masseter muscle. To determine whether there is a measurable …
Development of a Biomarker Panel for the Earlier Prediction of Acute Kidney Injury in Patients With Diabetes
Patients living with diabetes mellitus have double the risk of kidney failure compared to patients without diabetes following use of dye in many x-rays and procedures to diagnose and treat narrowing of the arteries (blood vessels) in the heart that can lead to angina or a heart attack. Heart disease …
