Filter by:The purpose of this study is to predict the CT visual score of emphysema with EIT-based parameters, in order to provide a non-invasive and convenient method for the evaluation of lung structure and physiological and pathological progression of COPD.
REDICAE trial was designed to evaluate the safety and tolerability of diuretics withdrawal in stable, euvolemic chronic outpatients with heart failure with reduced ejection fraction. It is a single-center, randomized, open-label, phase II clinical trial.
Investigation of the correlation of CT-morphological changes of the lung compared to regional ventilation distribution on electrical impedance tomography in patients with post-acute-Covid-19 symptoms.
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 infants.
This is a prospective observational study which will recruit up to 1200 participants over a two-year period to investigate whether non-invasive methods such as bioelectrical impedance analysis parameters and urine metabolic profile are predictors for pediatric non-alcoholic liver disease.
The consensus therapeutic strategy implies that COVID patients with acute lung injury due to coronavirus are routinely placed in prone position in an attempt to improve oxygenation by increasing ventilation homogeneity. The purpose of the study is to quantify with the electrical impedance tomography (EIT) the changes in the ventilation and aeration in the dorsal regions of the lung when the patient is placed in prone position.
The assessment of muscular function, quality and ability is of high importance in a diverse range of clinical disciplines from anaesthetics to physiotherapy. This study will look at the range of measurement techniques currently in use and development and considers their effectiveness and objectivity. It will also investigate whether an objective measurement technique can be found or developed that can be used both in the clinical environment and the community setting. This will focus on upper limb function and ability; ability is used here instead of strength since ability better describes functions needed for daily living rather than the maximum output a muscle is capable of.
The fluid overload measured by the Body Composition Monitor (BCM Fresenius Medical Care) is a new independent risk factor of mortality. This risk has already been described in intermittent hemodialysis patients and peritoneal dialysis patients but never evaluated in Daily Home Dialysis with low dialysate flow. The investigator propose a first study measuring the state of hydration by impedancemetry (BCM) in this population. The aim of this work is to to analyze hydration status in a representative sample of prevalent Daily Home Dialysis with low-flow Dialysate patients. Secondary objectives are to identify associations between hydration status and patient characteristics and treatment practice in order to find out which conditions should alert the clinician to potential fluid overload, to compare these results with the peritoneal dialysis population and in center hemodialysis population, to evaluate the correlation between impedancemetry and blood pressure in this population, to assess the nutritional status and evaluation of a new method of measurement of kt / V based on impedancemetry, without recourse to a blood test.
Bioelectrical impedance analysis is studied as a bedside tool to estimate capillary leak in order to guide dosing of hydrophilic antimicrobials.
Reflux is common, especially after large meals. In general, this can do no harm. However, if reflux occurs often and causes troublesome symptoms and or complications, it is called gastroesophageal reflux disease (GERD). Long exposure to gastric acid causes the mucosa of the esophagus to loose its integrity, which is thought to lead to the symptom of heartburn. Several food products can also impair the esophageal mucosa integrity and thereby influence reflux symptoms. One of these products is capsaicin, the pungent ingredient of red peppers. Use of capsaicin often leads to worsening of complaints in patients with GERD and can cause symptoms in healthy volunteers, possibly due to its effect on the mucosal integrity. In this study the investigators want to investigate the effect of capsaicin infusion on mucosal integrity. The investigators will evaluate mucosal impedance and the histology of the esophageal mucosa. In addition, the investigators also aim to assess the involvement of the TRPV1 receptor by evaluating the possible release of neuropeptides in the esophageal mucosa.
