Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), affects over 2 million people worldwide . Although biological therapies have significantly improved the treatment outcomes for UC, nearly two-thirds of patients experience diminishing drug responses over time, making it crucial to explore novel therapeutic approaches targeting the underlying pathophysiology of UC. UC is associated with alterations in gut microbiota, reduced microbial diversity, and changes in the relative abundance of dominant bacterial populations. Specifically, UC patients exhibit a marked decrease in gut microbiota diversity at the species level, with a reduction in Firmicutes (e.g., Clostridium butyricum) and an increase in Actinobacteria, Proteobacteria (e.g., Escherichia coli), Enterobacteriaceae, Streptococcus, and Bacteroides . Given the association between gut microbiota alterations and IBD activity, several studies have proposed microbiota-based therapies, particularly fecal microbiota transplantation (FMT), as a treatment for UC.

Background: Autoimmune diseases can be caused by genes people inherit from their parents. The gene changes that cause these diseases have been well studied in people with European and Asian ancestors. But some diseases behave differently in people who are native to North and South America. Researchers want to know more about the gene changes and other factors that may cause autoimmune diseases among these people. This project will be based in Peru. Objective: To study how gene changes can lead to autoimmune diseases in people native to Peru. Eligibility: People aged 18 years and older with an autoimmune disease. These may include systemic lupus erythematosus; Sjogren disease; scleroderma; rheumatoid arthritis; seronegative spondylo-arthropathies; and systemic vasculitis. Family members and healthy volunteers are also needed. Design: Participants will have 2 clinic visits; these will be 2 weeks apart. The clinics will be in Lima, Iquitos, and other sites in Peru. Visit 1: Participants will have a physical exam. They will answer questions about their health risks and habits. They will provide blood and urine samples. Visit 2: Participants will provide a second blood sample and a stool sample. They will talk about the results of their first clinical exam with researchers. The cost of travel to and from the clinics will be provided. Participants will get $30 per visit and a snack.

This study aims to evaluate the efficacy of fecal microbiota transplantation on the gastrointestinal symptoms, autistic symptoms and emotional behavior symptoms of patients with autism spectrum disorder, and investigate the relations between the brain-gut axis, cytokines and autism spectrum disorder. Fecal microbiota transplantation have the potentials to improve intestinal microbiota composition, regulate immunity, and then improve gastrointestinal symptoms, autistic symptoms, emotional behavior symptoms and sleep of children with autism spectrum disorder. Early intervention at school-age may even benefit development, improve cognition and prognosis.
NCT06595940
Background: Genetics research over the past 20 years has helped researchers find the causes of many diseases. More powerful tools for genetic testing now exist. Researchers want to use these new tools to learn more about genetic diseases. They want to look for possible genetic causes of unusual diseases. They will focus on people who live outside of the United States and whose access to genetic testing has been limited. Objective: To look for potential genetic sources of diseases among children and their families. Eligibility: Children aged 2 to 18 years and their related family members who have or may have a genetic disease. They will reside primarily outside of the US. Design: Participants will be recruited at sites outside of the US. Participants will be screened. Their existing medical records will be reviewed. They will have a physical exam. They will answer questions about their family history and symptoms. Participants will provide samples for genetic testing. They may have blood drawn. They may spit saliva into a small container. They may have a cotton swab rubbed on the inside of the mouth. The samples will be shipped to the NIH for genetic testing. Participants will be notified if testing reveals a known disease. Participants may be asked to provide new samples to confirm the diagnosis. Local study teams will contact the participants about the results. Participants will also be notified if analysis yields gene variants that may cause disease.

More than 7.4 million people in the UK are currently waiting for surgery. Behind that number are real people-patients preparing mentally and physically for procedures ranging from joint replacements to major heart and abdominal operations. This research forms part of a broader strategy known as prehabilitation - preparing the body before surgery to improve outcomes afterward. For patients waiting for surgery, it represents a shift from passive waiting to active preparation. Heart surgery for bypass or valve replacements results in inevitable yet controlled trauma. It increases inflammation, stress hormones and immune system demand. The body then has to repair itself - quickly and efficiently. And here's the surprising part. Inside your gut live trillions of bacteria - called your gut microbiome. These bacteria help regulate inflammation, strengthen your immune system and protect against infection. This randomised clinical trial is investigating a fascinating question: Can improving your gut microbiome through consumption of fibre before surgery help you recover faster, reduce time in ICU, shorten hospital stays, and lower complication rates? The placebo controlled trial will randomise 80 patients following eligibiilty checks to either 5g of prebiotic fibre/300mg of magnesium (WellBiome) OR 5g of maltodextrin for a period of 6-8 weeks prior to surgery. Patient will provide blood, urine and faecal samples at baseline and upon admission for surgery, and two further blood samples at day 3 and 6 post operatively. Following surgery, patient outcomes will be assessed and compared between the experimental group (prebiotic fibre/magnesium) and placebo group (maltodextrin). The investigators are focussing on the time spent in the intensive care unit, complications and overall hospital stay. By documenting and quantifying these the investigators can calculate the costs and any savings between the groups.

* Hypoparathyroidism is the most common complication after a total thyroidectomy surgery. It becomes permanent after 6 months. * Untreated permanent hypoparathyroidism is a source of numerous complications in general and therefore requires lifelong replacement therapy resulting in a significant deterioration in quality of life. * The intraoperative use of indocyanine green (ICG) angiography has recently been described as a reliable means of detecting parathyroidism and predicting the risk of postoperative hypoparathyroidism. * This use could prove to be a way to preserve parathyroid in vivo and thus reduce post-operative hypoparathyroidism rates.
NCT06315556
This is an observational study in which only data from babies with retinopathy of prematurity (ROP) who are being treated with aflibercept (Eylea) in prefilled syringe (PFS) using a paediatric dosing device (PDD) are collected and studied. ROP is a condition that affects the eyes of preterm babies. It occurs when the baby's retina, the part of the eye that senses light, does not develop normally. This may result in vision problems, including blindness, if left untreated. Preterm babies are born before 37 weeks of pregnancy. ROP is more likely to develop in babies who are born before 32 weeks of pregnancy or weigh less than 1.5 kilograms at birth. Aflibercept is a drug that is injected into the eye. It works by blocking a protein called vascular endothelial growth factor (VEGF) which causes abnormal growth of blood vessels in the retina. Aflibercept in PFS given using a PDD is approved for the treatment of babies with ROP. The prefilled syringe will be fitted with an injection needle to give aflibercept. And a PDD is a tool used to give the right amount of aflibercept to children in a safe manner. Since there are other treatments which are commonly used for babies with ROP, the extent of use of aflibercept given using a PDD is unknown. The main purpose of this study is to: * find the number of preterm babies who are treated with aflibercept using a PDD in the UK * inform whether this number is enough to perform a study to learn about the long-term safety of aflibercept given using a PDD in babies with ROP An additional purpose of this study is to describe characteristics including age, sex, and race, and signs and symptoms of ROP observed in babies being treated with aflibercept using a PDD. The data will come from a database called the National Neonatal Research Database. The study will cover the period from March 2024 to March 2025, if the number of babies found is enough to perform the safety study. If not, data will be collected till April 2027. In this study only available data from preterm babies born during the study period are collected. No visits or tests are required as part of this study.

The goal of the Precision Diagnosis in Inflammatory Bowel Disease, Cellular Therapies, and Transplantation (PREDICT) trial is to apply a systems-biology approach to enable precision diagnostics for the key immunologic outcomes for patients with Inflammatory Bowel Disease, Cellular Therapeutics and Transplantation. This approach will deepen the understanding of the molecular mechanisms driving auto- and allo-immune diseases and serve as a critical platform upon which to design evidence-based treatment paradigms for these patients. This research study will examine the immunology of auto- and allo-immune gastrointestinal disturbances such as Inflammatory Bowel Disease (IBD), Graft-versus-Host Disease (GVHD), and Functional Gastrointestinal Disorder (FGID), as well as the immune manifestations after CAR-T and other cellular therapeutics. The Investigators seek to use blood and tissue samples in order to better understand the mechanisms driving these diseases and their therapies. The Investigators further hypothesize that longitudinal systems-based immunologic analysis will enable the patient-specific determination of the molecular evolution of IBD, GVHD and the response to cellular therapeutics, as well post-transplant defects in protective immunity, and determine which pathways, when perturbed, can cause clinical disease. The discovery of these pathways will lead to improved diagnostic, prognostic and treatment approaches, and to personalized therapeutic decision-making for these patients.

In just a few years, intravitreal injections have become a standard method of administration for certain retinal deseases (age-related macular degeneration \[AMD\], diabetic edematous maculopathy or retinal vein occlusion \[RVO\]). Thus, vascular endothelial growth factor (anti-VEGF) inhibitors are injected repetitively, every 4 to 6 weeks, in some patients in order to treat such pathologies. It is established that each of these IVTs has repercussions on the intraocular pressure (IOP) of patients. They immediately present with an intraocular pressure spike (IOP reaching nearly 50mmHg) for a duration of a few minutes (between 15 and 30 minutes) when the injected volume is 0.05mL, which is currently used. In order to reduce the frequency of injections in patients, higher concentrations of active ingredients with anti-VEGF properties will arrive on the market with higher injection volumes of up to 0.07mL (marketing of Aflibercept 8mg/0.07ml in France since 01/06/2025. As IOP spikes are linked to the volume injected, the repercussions of such volumes could probably be greater and require additional actions. Indeed, currently the volumes used (0.05mL) rarely lead to complications such as transient blindness secondary to ocular hypertonia. In this case, an anterior chamber puncture may be necessary. To date, the impact on IOP of the 0.07mL injection has not yet been evaluated in the short and long term. Indeed, the repetition of IVT leads to a repetition of IOP peaks of around 50mmHg in the same patient. Some studies have analyzed the anatomical repercussions on the optic nerve of these peaks and have noted a reduction in the thickness of the peripapillary nerve fibers (RNFL for Retinal Nerve Fiber Layer) in Optical Coherence Tomography (OCT for Optical Coherence Tomography) after the 3 monthly IVTs recommended for the induction phase of treatment. But other studies have not found a significant drop in RNFL after several years of regular treatment with IVT. The studies were all carried out with volumes of 0.05mL and the repercussions with a volume of 0.07mL are therefore not reported in the literature. The AFLIPIO study aims to study the short-term pressure profile after performing an IVT of Aflibercept, at a volume of 0.07mL, and to evaluate the longer-term anatomical repercussions (12 months) on the head of the optic nerve when repeating IVT of Aflibercept, at a volume of 0.07mL.
NCT07025291
The aim of this study is to compare the salivary levels of HIF-2 alpha, MMP-9, and TRAP-5b among healthy individuals, patients with gingivitis, and patients with periodontitis; to examine the relationship between these levels and clinical parameters; and to determine their effectiveness in distinguishing periodontal disease from a healthy condition. It will be evaluated whether these biochemical mediators can be used as diagnostic biomarkers in the diagnosis of periodontal disease. Periodontal health is defined as the absence of signs of inflammation. Gingivitis is an inflammation of the gums and, if left untreated, can progress to periodontitis, a more severe condition characterized by the destruction of the supporting structures of the teeth. In this destruction, the host immune response to bacterial products and various inflammatory mediators (cytokines, MMPs) play a role. MMP-9 plays a significant role in the progression of inflammation and tissue damage. HIF-2 alpha is a factor that regulates bone formation and resorption and is activated in hypoxic or inflammatory environments. TRAP-5b is a specific marker of osteoclast activity and bone resorption. In the literature, there is no study that evaluates these three biomarkers together in saliva samples in the context of periodontal disease. This study aims to investigate the changes in these salivary biomarkers in the presence of periodontal disease, their diagnostic potential, and their relationship with clinical parameters. The findings may also provide insights for future treatments targeting these cytokine pathways.
NCT03730051
In this randomized clinical trial, the investigators expect to demonstrate that the MRI contrast agent Dotarem is not less effective in contrast enhancement of breast lesions then Gadavist. Participants will be randomized to receive either Dotarem or Gadavist. In all cases, inclusion criteria will require patients having undergone or scheduled or most likely to be scheduled to undergo tissue sampling with histology results available. The patients will be prospectively and consecutively identified such that the majority of patients included will have been diagnosed with breast cancer, while including benign disease in the minority of patients in each arm. Following randomized enrollment, quantitative, semi-quantitative and qualitative image analysis will be performed to objectively assess for differences in image quality and diagnostic value.

NCT04784351
This is a retrospective observational study drawing on data from the Brigham and Women's Home Hospital database. Sociodemographic and clinic data from a training cohort were used to train a machine learning algorithm to predict length of stay throughout a patient's admission. This algorithm was then validated in a validation cohort.
NCT06833957
Infections are one of the key causes of newborn deaths. Among them, Group B Streptococcus (GBS) is the leading cause of sepsis and bacterial meningitis in the first 90 days of life. Fortunately, GBS vaccines for pregnant women, a powerful tool for fighting infections, are currently in development. Once vaccine trials are completed, these vaccines can stop preventable newborn deaths. The PReparing for Optimal Phase III/IV maTErnal Group B StreptococCal vaccine Trials in Africa (PROTECT) project, funded by the European \& Developing Countries Clinical Trials Partnership (EDCTP) and European Commission, is supporting medical sites in Kenya, Malawi, Mozambique, and Uganda to establish uniform pregnancy and infant health data collection processes. It is also establishing surveillance of GBS in newborns to determine incidence rates and measure the burden of disease. With better reporting systems, medical sites can participate in vaccine trials and monitor vaccine safety. At the same time, the consortium is working to understand the drivers of vaccine hesitancy and to develop culturally appropriate communication tools to facilitate engagement with vaccines. The end goal is to set up a network of sites that can monitor vaccine safety for current and future vaccines.
