Active clinical trials for "Gastrointestinal Diseases"

The goal of this clinical trial is to study the effect of peppermint oil in in children with bladder and bowel dysfunction. The main question it aims to answer is: Does peppermint oil improve symptoms of bladder and bowel dysfunction among children? Participants will: Be provided peppermint oil capsules to be taken 3 times daily for 8 weeks. At baseline and at a follow-up visit (8 weeks later), participants will be asked to complete the Vancouver Nonneurogenic Lower Urinary Tract Dysfunction/Dysfunctional Elimination Syndrome Questionnaire. Researchers will compare baseline and follow-up questionnaire data for each participant to determine if there is improvement in symptoms of bladder and bowel dysfunction.

The aim of this multicenter, prospective, randomized, double-blind and large sample study is to explore the preventive effect of low-dose droperidol on POD in elderly patients after non-cardiac surgery, providing new approach for reducing the incidence of POD and improving the prognosis and quality of life.

IMPROVE-IT2 is a randomized multicenter trial comparing the outcomes of ctDNA guided post-operative surveillance and standard-of-care CT-scan surveillance. The hypothesis of this study is that ctDNA guided post-operative surveillance combining ctDNA and radiological assessments could result in earlier detection of recurrent disease and identify more patients eligible for curative treatment.

To compare the frequency of regurgitation and other digestive outcomes between infants who receive an infant formula based on whole goat milk and an infant formula based on cow milk proteins during the transition period from breastfeeding to formula feeding, using predominantly breastfed infants as a reference group.

In this study, methylene blue (MB) was used as vital nerve staining agent. During gastroenteroscopy, mucosal nerve staining was achieved by endoscopic submucosal injection of MB solution. To observe the staining of nerve fibers, neurons and glial cells in mucosa and submucosa, as well as the morphological changes, density differences and function of mucosal nerve tissues in different gastrointestinal lesions, in order to explore the role of endoscopic vital nerve staining in the diagnosis of gastrointestinal lesions.

Open label interventional randomized pilot study utilizing two dosing regimens of AEMCOLO. The goal of this study is to evaluate effectiveness of a novel antibiotic, AEMCOLO (Rifamycin SV MMX) in the treatment of Small intestinal bacterial overgrowth (SIBO).

This is a multi-site comparative effectiveness randomized controlled trial (RCT) comparing annual fecal immunochemical testing (FIT) and colonoscopy for post-polypectomy surveillance among adults aged 70-82 with a history of colorectal polyps who are due for surveillance colonoscopy.

The increase in the tension of the soft tissues around a nerve restricts the movement, affects the function of the nerve, and makes the nerve vulnerable to entrapment. Even a mild nerve compression can cause entrapment and lead to neuroinflammation. It is known that inflammatory mediators amplify axonal sensitivity. Although the spontaneous discharge potential of visceral afferents is quite low under normal conditions, neuroinflammation increases the excitability of these fibers. With this mechanism, hyperalgesia may develop in sensory fibers in neuroinflammation. This may cause pathologies in the organs innervated by the relevant nerve. The fascia and muscles of the cervical region surround the vagus nerve. There are two main fascial compartments in the cervical region. The SCM and trapezius muscle fascias join to the most superficial fascia of the deep cervical fascia and they together form these compartments. These fasciae superiorly attach to the cranium and inferiorly to the pectoral region. The vagus nerve emerges from the jugular foramen together with the 9th and 11th cranial nerves. It then continues through the carotid sheath in the cervical region. The carotid sheath is in contact with the SCM muscle. For this reason, it can be thought that SCM muscle tension or thickness may affect the carotid sheath and thus the function of the vagus nerve passing through it. In summary, deterioration in vagus nerve activity plays a role in pathologies of the organs innervated by the vagus. Although the relationship between vagal dysfunction and gastrointestinal system symptoms is clear, the mechanisms affecting vagus nerve function have not yet been clarified. It has been reported in the literature that some maneuvers from the cervical region are also effective on the vagus nerve. Also, according to investigators' clinical experience, gastrointestinal symptoms are frequently observed in patients with increased cervical soft tissue tension. However, there are not enough studies investigating whether the cervical region soft tissue tension can affect the gastrointestinal system via the vagus nerve. Therefore, this study was planned to examine the relationship of cervical soft tissue tension with vagus nerve function and gastrointestinal symptoms in asymptomatic individuals and individuals with neck pain.

Background: Chronic granulomatous disease (CGD) is a disease of the immune system, which is how the body fights germs. People with CGD get infections easily and have other health problems. Some medicines to treat CGD have a lot of side effects and do not always work. Researchers want to see if a new drug can help. Objective: To see if tofacitinib is safe to use for treating chronic CGD. Eligibility: Adults aged 18 and older with CGD who have not had success with other treatments and who are enrolled on NIH study # 93-I-0119. Design: Participants will be screened with the following: Physical exam Medical history Blood, urine, and stool tests Pregnancy test, if needed An upper gastrointestinal endoscopy and/or colonoscopy, if needed for their symptoms. Tissue samples will be collected. Skin assessment, if needed Participants will repeat some screening tests at visits. Participants will complete questionnaires about their general health and how CGD affects their daily life. Photographs will be taken of their skin, if needed. They will have lung function tests, if needed. They will have a computed tomography (CT) scan of the chest, abdomen, and pelvis, if needed. A CT scan uses X-rays to create pictures of the inside of the body. Participants will gradually reduce the amount of some CGD medicines they take. Then they will take tofacitinib as a pill twice a day for 3 months. They will keep a drug diary. They will have monthly study visits. They will have a follow-up visit about 1 month after their last study drug visit. Participation will last for about 6 months.

This is a combined retro- and prospective, monocentric study. All patients who underwent or are planned for laparoscopic partial fundoplication (180° anterior or 270° posterior) between 2020-2023 are assessed for preoperative ineffective esophageal motility (IEM). The main hypothesis is, that preoperative oesophageal motility disorders, especially hypo-contractility or failed peristalsis, are caused by gastro-oesophageal reflux. Therefore, postoperative manometry after partial wrap fundoplication (270° posterior, 180° anterior) shows a decrease in comparison to preoperative motility disorders. The primary objective of this study is to examine the postoperative esophageal motility in patients with known preoperative motility disorders. Secondary endpoints are the presence of other oesophageal motility disorders pre- vs. postoperatively (including new onset disorders), the assessment of the Gastrointestinal Symptom Rating Scale (GSRS) pre- vs. postoperatively, and more. If IEM is present preoperatively, patients are contacted at least 1 year after surgery and will be informed about the study and asked to participate. In case of agreement, they are invited to the study site. They undergo high-resolution manometry 18-24 months postoperatively (study intervention).
