Gastroesophageal reflux disease (GERD) is a chronic disorder marked by heartburn and regurgitation, resulting from the reflux of gastric acid or bile into the esophagus. Chronic acid exposure leads to mucosal inflammation, erosive esophagitis, and Barrett's esophagus, conditions that increase the risk of esophageal adenocarcinoma (Badreddine RJ et al., 2010; Fass R, 2022). Obesity, defined by the World Health Organization as a body mass index (BMI) ≥30 kg/m², is recognized as a major global public health issue due to its rapidly rising prevalence and strong association with chronic disease. It is not only a cause of metabolic disorders but also a driver of systemic health complications (WHO, 2024). Obesity is linked with type 2 diabetes, cardiovascular disease, hypertension, non-alcoholic fatty liver disease, certain cancers, and sleep apnea. Additionally, it negatively impacts psychological well-being, contributing to depression, low self-esteem, and social stigma (CDC, 2024). Evidence suggests a strong link between obesity and GERD. Studies demonstrate that obese individuals exhibit higher intra-gastric pressure, delayed esophageal transit, increased esophageal acid exposure, and a greater prevalence of defective lower esophageal sphincter function. These pathophysiological mechanisms contribute significantly to GERD development and its complications (de Vries DR et al., 2008; Cote-Daigneault J et al., 2014; Anggiansah R et al., 2013; Ayazi S et al., 2009). The rationale for this study is to explore the relationship between obesity and GERD, given the rising prevalence of obesity and its implications for gastrointestinal health. Diagnosis of GERD is primarily clinical, based on symptoms such as heartburn and regurgitation. A trial of proton pump inhibitors for 4-8 weeks is recommended in patients without alarm features. Endoscopy is indicated for those with alarm signs or refractory disease, while pH monitoring is the gold standard in uncertain cases. Manometry is reserved for pre-surgical evaluation (Katz PO et al., 2022).To study the relationship between Obesity and GERD, given the rising prevalence of obesity and its potential impact on gastrointestinal health.

Gastroesophageal reflux disease (GERD) occurs when stomach acid repeatedly flows back into the tube connecting your mouth and stomach (esophagus). This backwash (acid reflux) can irritate the inner lining of the esophagus. This is a particular problem after surgery to reduce obesity called gastric sleeve resection. The goal of this small clinical trial is to examine the effect of endoscopic treatment of GERD by mucosal band ligation. The main questions it aims to answer are: * Does the treatment affect gastroesophageal reflux assessed by measuring gastroesophageal reflux * Does the treatment affect gastroesophageal reflux symptoms and ability to stop treatment with medication commonly used (proton pump inhibitors) Participants (n=12) will be asked to undergo 24 h reflux examination and report symptoms of GERD. Suitable patients will be offered endoscopic treatment with band ligation of the inner lining of the lower esophagus and upper part of the stomach. The effects will be assessed three and six months after the procedure.
NCT05989698
The goal of this clinical study is to validate C-mo System's ability to automatically detect and characterise cough, in patients over 2 years old with cough as a key or refractory symptom. The main questions it aims to answer are: 1. Can C-mo System detect cough events? (automatic cough detection) 2. Can C-mo System characterise cough events? (calculation of cough intensity, identification of cough type and presence of wheeze in detected coughs) Participants will be asked to: * Wear the C-mo Wearable device for 24 hours (1 day); * Complete a diary with relevant activities throughout the monitoring period; * Fill-out questionnaires related to coughing frequency and intensity, usability of the device, and impact of cough on quality of life.

The measurements included: A. By measuring the Maximum Inspiratory Pressure (MIP) (Micro RPM) B. By measuring the Maximum Dynamic Inspiratory Pressure s-index (Powerbrethe K5) The following instruments were included in the secondary outcome measures: * Recurrent Gastroesophageal Reflux Disease Questionnaire (measurement of symptom frequency-RDQ Questionaire). * Gastroesophageal Reflux Disease-Related Quality of Life Questionnaire (Quality of Life Measure-Reflux Qual short form questionnaire).
NCT05180253
The evaluation of the foregut, the esophagus and stomach, has come a long way over the past two decades, and continues to experience exciting discoveries in the clinical evaluation of foregut physiology. Assessing esophageal peristalsis has relied for the past several decades on High Resolution Manometry (HRM), however it has recently become known that even though HRM is an extremely effective tool, that there are certain subsets of patients in which additional information is required. Additionally, the assessment of esophageal reflux disease has relied on pH impedance for the last two decades. However, this procedure requires a catheter to be passed through a nostril and remain in place for at least 24 hours. Novel techniques, already FDA approved, including EndoFLIP for esophageal peristalsis and mucosal integrity (MI) for reflux disease, have emerged as time-of-endoscopy assessments. Both involve the placement of a balloon through the scope at time of upper endoscopy (standard first line assessment for both dysphagia and reflux symptoms) and are quick and pose little-to-no additional risk or discomfort for patients. However, data regarding normal esophageal parameters are poorly defined for both EndoFLIP and MI. Additionally, EndoFLIP has increasingly been used to assess the pylorus, and scarce data exists there regarding how a tool originally envisioned for esophageal assessment can be used more distally in the GI tract. We will recruit healthy, asymptomatic volunteers to undergo testing with MI and FLIP (esophageal and pyloric). The data obtained will help establish the benchmark from which assessments can be made in patients.
NCT03202537
The prevalence of GERD is estimated to be as high as 20% in the US, and up to 50% remain symptomatic on proton pump inhibitor (PPI) therapy. The clinical approach to understand the mechanism of nonresponse is not standardized, and patients will often undergo various tests: 1) pH-impedance, 2) wireless pH monitoring over 96 hours, 3) high-resolution impedance manometry (HRIM), and 4) mucosal impedance (MI). Controversy exists regarding the best technique, optimal study protocol and treatment approach for the PPI non-responder (PPINR) group, resulting in inappropriate resource utilization and a failure to provide effective personalized care. The first aim is to identify the relevant physiologic parameters of diagnostic tools in their ability to predict PPI requirement. In Aim Two, these results will be applied to guide the formal development of a clinical algorithm for the management of PPINRs with personalized clinical pathways based on mechanism of treatment failure. We will first perform a prospective comparison trial of 240 PPINR subjects at 2 sites over 4 years. Subjects will complete symptom questionnaires and undergo diagnostic testing (pH-impedance on PPI therapy, HRIM, 96-hr wireless pH monitoring off PPI therapy and MI). Those who have a positive pH study and/or resume PPI therapy will receive escalation of therapy with dexlansoprazole. We will compare the ability of 96-hr wireless pH monitoring vs pH impedance to predict PPI requirement and response to dexlansoprazole, respectively. We will explore whether MI is equivalent to 96-hr wireless pH monitoring in predicting PPI requirement. Lastly, we will determine whether HRIM metrics can be utilized to determine reflux burden, mechanism and response to treatment. Next, the investigators will develop quality measures for reflux testing in order to develop a simplified management strategy for the PPINR group. The RAND/UCLA Appropriateness Methodology will be utilized with an expert working group to develop formal validated quality measures for reflux testing.
NCT05296655
Reflux symptoms index (RSI) were developed to identify a clinical index of suspicion for laryngopharyngeal reflux (LPR) in patients with ear, nose, and throat symptoms. RSI is an efficient diagnostic tool for LPR/ It is easy to use, even for those who know little about LPR. It does not require special equipment or examinations and is inexpensive. Thus, it can be considered highly efficient and cost-effective. The study will focus on translating and testing the RSI into Kazakh language and comparing its results in healthy people and people with laryngopharyngeal reflux.
NCT04846010
Post-acute sequelae of SARS-CoV-2 infection can cause multiple system function disorders, and complicated symptoms last for an extended period. The virus can cause this continued infection, or the virus causes immune system function disorder and post-infectious autoimmune disease. The clinical symptoms can be smell loss, taste loss to liver function disorder, kidney function failure, different. No matter how complicated the systems showed in the clinic, all of the symptoms are due to the specific cells being damaged. Our clinical study is focused on recovering the damaged structure and function of the cells that could restore the organ function back to normal or close to normal

NCT03282084
Gastroesophageal reflux disease (GERD) is a common chronic condition, affecting approximately 20% of the American adult population. Proton pump inhibitors (PPIs) are now the mainstay of medical therapy for symptoms of GERD. Despite their efficacy, several studies have shown that a significant proportion of GERD patients are either partial or non-responders to PPI therapy, defined as symptoms of heartburn and/or regurgitation not relieved by either a standard or double dose of a PPI during a minimum trial of 8 weeks. If GERD symptoms persist, further testing is required. This study will mirror the real world setting to assess the value of published guidelines which recommend specific testing and treatment.
