Active clinical trials for "Digestive System Diseases"

To select among different dietary and clinical conditions the most appropriate to assess the impact of a fermented milk product on gas-related symptoms

To assess the frequency and nature of adverse events in infants fed a free amino acid based infant formula.

The waiting lists for surgery and diagnostic tests registered in the health management area of Campo de Gibraltar West are very high, and this is compounded by the lack of resources that prevent them from being managed efficiently. The aim of the study is to know, quantify and communicate the measurement of the social impact, also known as social return on investment, which is presented as a tool for decision making on the intervention of the management of health concerts in comparison with the current system in Andalucia. In addition, other objectives will be studied, such as the health and non-health benefits derived from applying the intervention of the concerts compared to the current system of waiting list management from the economic, social and environmental points of view, the economic cost of the interventions by the health concerts and the Andalusian public health system, the cost of the increase in extraordinary health resources, determining the most prevalent surgeries from highest to lowest and specifying the highest number of surgeries that are established in the concerts and in the SSPA. The method used will be an economic evaluation of the different healthcare technologies in which the investigators compare the healthcare agreements of the most prevalent procedures and those that collect data in both groups through the SROI tool. A cross-sectional and prospective design will be carried out with a time horizon of 2021 and 2022, and for the statistical analysis the investigators will use the SSPS V25 and JASP programmes. The investigators consider it necessary to carry out this research study as there is no specific bibliography on the healthcare technology used in healthcare agreements as a new healthcare technology compared with the current system for managing surgical waiting lists in the Andalusian public healthcare system in terms of return on investment.

Several studies have been done on the efficacy of the herbal medicine Iberogast. In this study researcher want to learn more about the time needed for Iberogast to start to work after the patient took the drug. This study plans to enroll 300 adult male and female patients suffering from disturbance of stomach and intestine normal function and treated by their doctor with Iberogast drops. Patients will be asked to document on a diary card the changes of symptom severity of the stomach and intestine complaints and the time needed for the symptoms to improve after drug intake. At the end of the study the treating doctor and the patients will be asked about the overall changes of symptoms. In addition information on the safety of the drug and how well the drug is tolerated by the patients will be collected

This study aims at collecting the information related to the safety and effectiveness in the pancreatic exocrine insufficiency patients due to cystic fibrosis receiving the treatment with LipaCreon in order to evaluate the effective and safe use of LipaCreon.

Under daily routine conditions and without any intervention by the sponsor regarding the selection of subjects, diagnostic procedures, therapeutic decisions (medicinal and non- medicinal therapy, dose, duration, etc.), routine assessments, the participating physicians (i.e. general practitioners and internists) are asked to document relevant data related to esomeprazole therapy in patients with gastrointestinal disorders. Patients with acid associated gastrointestinal symptoms can be included.

To analyze the prevalence of overlap syndromes among NERD or RH, FD, and IBS patients, and to identify and to compare the differences in their characteristics and symptoms, and to determine their risk factors. To identify the differences in clinical features according to sex and gender. To analyze the effect of genetic polymorphisms on overlap FGIDs over long-term follow-up period.

Background. Dyspeptic patients tolerate smaller meal loads than healthy subjects, but it is not known whether and to what extent symptoms relate to abnormal homeostatic or hedonic components of perception. Methods. Parallel studies in patients with symptoms induced by meals (fulfilling Rome IV criteria of postprandial dyspepsia) and sex- and age-matched healthy subjects. Participants will be instructed to eat a standard dinner the day before, to consume a standard breakfast at home after overnight fast, and to report to the laboratory, where the test meal will be administered 4 h after breakfast. Studies will be conducted in a quiet, isolated room with participants sitting on a chair. Participants will ingest a probe meal up to the level of maximal satiation. The probe meal will be served stepwise (112 Kcal every 5 min). Perception of homeostatic (hunger/satiation, fullness) and hedonic (digestive well-being, mood) sensations will be measured at 5 min intervals 10 min before, during and 20 min after ingestion at 10 min intervals.

Functional gastrointestinal disorders (FGID) are amongst the most common causes of abdominal pain and dysfunction seen in clinical practice, affecting between 10 to 15% of most populations (1). FGID are defined by symptoms without demonstrable underlying organic pathology (2). Within the currently used Rome definitions of FGID, there is a broad range of gastrointestinal and multi-organ symptoms, indicating heterogeneous underlying pathophysiological mechanisms (3). There is evidence of central nervous system and motility dysfunction, dysbiosis, as well as immune activation in various subgroups of patients with FGID (2). Most mechanistic studies have been performed in small and heavily selected groups of patients. Consequently, the link between different symptomatic subgroups of patients and underlying mechanisms is unclear and unconfirmed in larger and representative patient cohorts. FGID patients with different underlying pathologies are likely to benefit from divergent specific treatments, even if they fall within the same Rome classification of FGID. Discrete clusters of clinical characteristics in a large cohort of patients with FGID will be sought using hypothesis-free cluster analysis and latent-class analysis models. Associations to underlying mechanisms will be examined using data from fermentable sugar breath, blood and stool tests. This will allow recommendations regarding improved mechanistic-based classifications of patients with FGID, with potential for more effective mechanistic-based treatments. The investigators will use coded clinical and medical history characteristics obtained by standardized questionnaires and laboratory and breath test results from all successive patients above the age of 18 years referred to the Gastroenterology Group Practice in the last 10 years for diagnosis and treatment of FGID for statistical analysis The data is stored in a database, without any personal identifiers. Explorative statistical analysis will be performed in approximately 5000 patients.

Gastrointestinal (GI) motility disorders in intensive care patients remain relatively unexplored. Nowadays, the frequency, risk factors and complications of GI dysfunction during enteral nutrition (EN) become more questionable. Our aim is to evaluate the frequency, risk factors and complications of GI dysfunction during EN in the first 2 weeks of the intensive care unit (ICU) stay and to identify precautions to prevent the development of GI dysfunction and avoid complications.
