Acceptability, Adherence, and Impact on the Bioavailability of Iron and Zinc of the Dietary Supplements Goodphyte IB Defense and Goodphyte Immunity in Adults With Chronic Diseases.

The primary objective of the present postdoctoral research is to evaluate the acceptability and adherence of two dietary supplements containing microbial phytase, Goodphyte IB Defense and Goodphyte Immunity, in adult individuals with chronic diseases, namely Idiopathic Inflammatory Bowel Diseases (IIBD)-that is, Crohn's disease (CD) or Ulcerative Colitis (UC)-Arterial Hypertension (AH), Anemia (AN), or Multiple Sclerosis (MS). Secondarily, this study will investigate potential changes in iron and zinc absorption following phytase supplementation in these individuals and, consequently, possible changes in their quality of life.

Dose-finding Study of SAR443122 in Adult Participants With Ulcerative Colitis

This is a randomized, double-blind, placebo controlled, dose-ranging Phase 2 study. The primary objective is to evaluate the efficacy and safety of SAR443122 compared to placebo in participants with moderate to severe UC. Dose selection for further clinical development will be based on the multiple efficacy, safety and PK parameters. The study consists of 4 parallel arms (3 dose groups of SAR443122 vs placebo) to assess the efficacy and safety of SAR443122 in participants with moderate to severe UC. All participants will receive a total of 52 weeks (a 12-week induction treatment phase and a 40-week maintenance phase) of study treatment, except if treatment should be discontinued per investigator's assessment. At the end of the first 12 weeks of induction treatment, all participants in clinical response or remission will be offered study treatment up to 40 weeks and will continue with the same blinded treatment that was assigned. Participants who do not achieve clinical response or remission at the end of the initial 12 weeks induction treatment will roll over in an open-label treatment arm and will be treated with SAR443122 at the highest tested dose. In addition, participants from the maintenance treatment that lose clinical efficacy at any time up to V10/Week 40 (Week 28 of maintenance) will be offered to roll over in the open-label treatment arm with SAR443122 at the highest dose.

Effectiveness of Health Education as a Nursing Intervention in Improving Quality of Life and Reducing Symptoms of Anxiety and Depression in Ostomy Patients Following Digestive Surgery: A Quasi-Experimental Study.

The proposed project is a prospective quasi-experimental study to be conducted at the Ostomy Clinic of the University Hospital Complex of Santiago de Compostela. The primary objective is to evaluate the effectiveness of health education as a nursing intervention in reducing anxiety and depression and improving the quality of life of ostomy patients following digestive surgery. The study will focus on adult patients who have undergone an elimination ostomy, excluding terminal patients and those with cognitive impairments. The study involves clinical follow-up of patients from hospital admission to several months after completing the health education program. Validated scales will be used to measure quality of life, anxiety, and depression. The intervention will consist of health education workshops and continuous follow-up by specialized nursing staff.

Magnesium in Gastrointestinal Disease

Individuals with gastrointestinal diseases - such as Crohn's disease, ulcerative colitis, ileostomy, or bile acid diarrhoea - are at increased risk of magnesium deficiency. Magnesium is a vital mineral that supports many essential functions in the body, including muscle contraction, nerve signalling, heart rhythm, and bone health. Deficiency may contribute to fatigue, muscle cramps, abnormal heart rhythms, and reduce the quality of life. The purpose of this study is to investigate the prevalence of magnesium deficiency in individuals with these conditions and to identify the most accurate and practical methods for assessing magnesium status in clinical care. Although plasma magnesium is commonly used in routine blood tests, it represents only about 1% of the body's total magnesium and may not reflect true magnesium levels within cells or tissues. Hence, this study compares several different ways of measuring magnesium, including: * Plasma magnesium * Magnesium levels in red and white blood cells (PBMC, RBC, and buffy coat) * Magnesium levels in muscle tissue (via biopsy) * A magnesium retention test, based on how much magnesium is excreted after an infusion The study includes four groups: 1. Patients with inflammatory bowel disease. 2. Patients with an ileostomy. 3. Patients with bile acid diarrhoea. 4. Healthy individuals (control group). All participants will provide blood and urine samples, and some may undergo optional biopsies of muscle or intestinal tissue. Participants will also complete questionnaires and undergo tests of muscle strength and body composition. The findings are expected to enhance the understanding and detection of magnesium deficiency in patients with gastrointestinal diseases and to aid in the development of more effective tools for identifying and treating this common yet often overlooked condition.

LTS19689 is a multinational, multicenter extension study to evaluate the long-term safety, tolerability and efficacy of balinatunfib in participants with Crohn's disease (CD) or ulcerative colitis (UC) who completed the 52-week treatment period (on balinatunfib or placebo) in the parent studies, SPECIFI-CD (DRI18212) or SPECIFI-UC (DRI17822), respectively. * The primary objective of this study is to assess the long-term safety and tolerability of different doses of balinatunfib in participants with CD or UC, as measured by the number and percentage of participants with CD or UC with treatment emergent adverse events (TEAEs), serious adverse events (SAEs) and adverse events of special interest (AESIs) during the study period. * The study will consist of 2 independent cohorts through the study given the distinct nature of each disease: * CD Cohort: comprised of CD participants enrolled from SPECIFI-CD (DRI18212). * UC Cohort: comprised of UC participants enrolled from SPECIFI-UC (DRI17822). * The study will consist of the following study periods for each cohort: * A Double-Blind (DB) treatment period of up to 104 weeks for eligible participants from the DB maintenance phases of the respective parent studies. * An Open-Label (OL) treatment period of up to 104 weeks for: * Eligible participants from either the DB or OL periods of the parent studies, * Eligible participants who meet escape criteria at any time during the DB period of the LTS19689. * A 2-week follow-up period following the End of Treatment (EOT). The study duration will be up to 107 weeks, with the treatment duration up to 104 weeks.

OPTImization of Inflammatory Bowel Disease Treatment Through Understanding of Gut VIRome Heterogeneity

Title: The Role of Good Viruses in Inflammatory Bowel Disease Background An imbalance in the bacteria in the gut - called gut dysbiosis - is linked to chronic bowel diseases such as Crohn's disease and ulcerative colitis (IBD). A special and more severe form of IBD, called primary sclerosing cholangitis-associated IBD (PSC-IBD), affects both the gut and the bile ducts, and in serious cases can lead to liver failure. There is currently no cure for IBD. Research suggests that microorganisms in the gut, especially bacteria and viruses called bacteriophages, play an important role in how the disease develops. Treatment with stool from healthy donors, known as fecal microbiota transplantation (FMT), has proven effective against certain infections and has shown promising results in IBD. A newer and possibly safer method is fecal virome transplantation (FVT), where only the virus part (the gut virome) of the stool is used. Bacteriophages can kill harmful bacteria and help restore balance in the gut, but their use is still experimental. Therefore, we aim to develop a new treatment by growing bacteriophages from healthy individuals in the lab and using them to restore a healthy balance of bacteria and viruses in the gut of patients with IBD. Purpose of the study The long-term goal of the study is to improve treatment for IBD by gaining a better understanding of differences in the gut virome between IBD patients and healthy people. We also want to explore whether "fermented" bacteriophages from donor stool can be developed into a future bacteriophage-based therapy. This will be studied using experimental lab setups and animal models. The study will include 10 healthy stool donors and 30 IBD patients (10 with ulcerative colitis, 10 with Crohn's disease, and 10 with PSC-IBD). The study does not involve any treatments - only the collection of biological samples and access to information about your health from your medical record.
