Filter by:Gastroesophageal reflux disease (GERD) patients without obvious mucosal break by endoscopy were examined by FICE, followed by confocal. Validity scores for MERD diagnosis were analyzed.
Purpose: 1. Determine if oral quercetin increases the expression of claudin-4 in the lining of the esophagus of patients with a diagnosis of gastroesophageal reflux disease (GERD); and 2. Determine whether the increase in claudin-4 by oral quercetin is accompanied by improvement in the barrier function and acid resistance of the lining of the esophagus of patients with a diagnosis of gastroesophageal reflux disease (GERD) If interested, participants will be consented and provided a questionnaire to complete as part of the study. Participants will undergo endoscopy for routine care and will have up to 8 esophageal biopsies (small tissue samples) taken for the research study. After endoscopy, participants will be contacted to begin a 6 week treatment period with study drug (Quercetin, taken twice daily). At the end of the 6 week period, participants will be scheduled to have blood drawn and to have a follow-up endoscopy with biopsies performed for the research study.
Being able to accurately monitor patient bodily fluid levels during and after surgery is very important, as there are a number of complications that can arise if a patient's fluid levels become unbalanced, such as swelling within or pressure on various bodily organ systems. There are several different ways that physicians can monitor a patient's fluid balance during and after surgery, such as measuring the amount of urine output or the use of central venous catheters which measure the pressure in the veins entering the heart. Most of these techniques are invasive since they require tubes to be inserted into the body. A potential alternative would be to use a noninvasive technique such as electrical bioimpedance (BIA). Bioimpedance assessments work by using small electrical currents that can accurately predict both the water surrounding the outside of cells in the body, as well as the total amount of water in the entire body. Electrical bioimpedance assessments have been used to estimate patient swelling following surgery (edema), to measure the volume of blood the heart is pumping out, as well as to calculate body fat percentages. The goal of this study is to relate this technology to fluid shifts within the body that occur as a result of surgery, in particular, major intra-abdominal surgeries. By using bioimpedance during and after surgery, the investigators will compare the data collected with that calculated by using traditional measures of body fluid status, such as urine output and intraoperative blood loss. During the study, the bioimpedance monitors will not replace the standard bodily fluid monitors and will not interfere with their readings. Additionally, the electrical current produced by the bioimpedance monitors is too small for patients to feel and will not interfere with medical devices such as pacemakers.
Multicenter, comparative single-dose pharmacokinetic (PK) study
Gastroesophageal reflux disease is increasing worldwide. The causes of reflux symptoms are not found exactly. especially, the postprandial reflux symptoms are more common than the all day reflux symptoms. One of the causes of reflux symptoms is the relaxation of the lower sphincter of the esophagus. But, the sphincter relaxation also occur in normal people. But, there is a difference in postprandial reflux pattens between the patients and the normal people. So, in this study, we want to compare the difference of reflux pattern between the patients who have postprandial reflux symptoms and normal people though the 24hr pH monitoring.
The purpose of this study is to assess the efficacy and safety of rabeprazole 10mg once and twice daily in maintenance therapy for PPI resistant gastroesophageal reflux disease patients.
This clinical trial studies whether esophageal cytology plus fluorescence in situ hybridization (FISH) is equal to or better than esophago-gastro-duodenoscopy (EGD) or upper endoscopy for the early detection of esophageal cancer. Genes are the units of deoxyribonucleic acid (DNA) the chemical structure carrying genetic information that determine many human characteristics. Certain genes in cancer cells may determine how the tumor grows or spreads and how it may respond to different drugs. Part of this study is to test those genes in esophageal cells using FISH.
The purpose of this study is to measure the in-vivo disintegration time of a single dexlansoprazole delayed-release orally disintegrating (OD) tablet.
This study aims to determine the absolute bioavailability of YH4808 using simultaneous oral therapeutic- and [14C]-labeled intravenous microdoses.
Gastro-Esophageal Reflux is a commonly encountered problem in infants. After failure of medical therapy, many children are referred for surgical intervention. Techniques have evolved over the last 50 years; however, benefits in children remain the center of debate in many surgical forums. This is primarily owing to the high incidence of recurrence of reflux and need for revisions later in life. Some clinicians theorize that the pathophysiology of reflux in infants is different from that of the population at large, and that the traditional operation may not be the best suited for this patient population. We propose a study to test an alternative plication technique for modifying the gastro-esophageal junction at the Angle of Hiss. By plicating the cardia of the stomach, we hypothesize that we will create a valve which will limit reflux without disrupting the diaphragmatic crura, thus reducing the incidence of recurrent hiatal hernia and limiting the incidence of fundoplications which are too tight.
