Patients having knee replacement surgery regularly experience joint pain and compromised bone quality leading to implant loosening and periprosthetic fractures. The role of the gut microbiome, which is the collection of bacteria and other microbes within the human gastrointestinal tract, is just beginning to be recognized, including its potential effects on pain, infection, and loosening after total joint replacement. Antibiotics are regularly used in orthopaedic surgery to reduce the risk of infection, but they also harm gut microbiota and reduce their potentially beneficial effects. Probiotics may have a role to play in enhancing bone quality and decreasing synovial inflammation after joint replacement surgery, and this study will explore the potential relationship of probiotic use with implant migration, bone density, and patient outcomes. This study is a randomized, controlled, double-blinded trial comparing probiotic use with placebo in post-menopausal women undergoing primary total knee replacement. The main questions it aims to answer are: * to compare implant migration between groups from baseline to six weeks post-surgery * to compare bone density and joint inflammation between groups from baseline to six weeks post-surgery * to compare gut microbiome composition and patient-reported outcome measures between groups from baseline to six weeks post-surgery

This study aims to show how digestive enzyme supplements help the body break down fats, proteins, and carbohydrates, especially after eating a high-fat, high-protein meal. Digestive enzymes are essential for nutrient absorption, but some people-such as those with certain medical conditions or high-protein diets-may not produce enough on their own. Poor digestion can lead to bloating, discomfort, and gut imbalances. This clinical trial tests a delayed-release, porcine-derived enzyme blend to see if it improves digestion and reduces symptoms like bloating and gas after eating a high-fat and high protein meal.

The carbohydrate inulin (from chicory root) is a healthy prebiotic ingredient found in dietary supplements and fortified foods (Nagy et al). Inulin is representative of a broader class of typically health-associated, yet fermentable carbohydrates called fructans that occur naturally in many vegetables, fruits, and wheat. Fructans, or long chains of fructose units, are resistant to human digestive enzyme hydrolysis and transit intact to the small intestine and colon where they undergo rapid fermentation by intestinal microbes. This microbial metabolism of fructans produces gas and other fermentation byproducts that can lead to excess gastrointestinal (GI) symptoms like abdominal bloating, cramping, stomach rumbling, and flatulence (Bonnema et al; Briet et al; Bruhwyler et al), especially in individuals with irritable bowel syndrome (Van den Houte et al). A new digestive enzyme called fructanase was developed to help with GI symptoms associated with fructan consumption. Positive findings from in vitro digestion simulations (Guice et al) and a first-in-human safety trial (Garvey et al) helped define the fructanase dose for this clinical trial-the primary objective of which is to investigate the effect of oral fructanase administration on GI symptoms in healthy adults after consuming oatmeal with added inulin (25 grams). Secondary outcomes include breath hydrogen and methane levels, which serve as biomarkers of intestinal microbial fermentation. The investigators hypothesize that fructanase administration will lower the severity of GI symptoms after inulin consumption, as well as lower breath biomarkers of intestinal microbial fermentation, compared to placebo.

5-fluorouracil and capecitabine, sometimes called 5-FU, fluoropyrimidines, or Xeloda are a type of chemotherapy. Many people have side effects from these drugs like nausea, diarrhea, or blood problems. This research study is being conducted to learn how to help increase the number of patients offered DPYD testing before taking this type of chemotherapy drugs. DPYD testing can help predict risk of side effects. Different people's bodies break down and use drugs faster or slower. Genes are the instructions that tell our bodies how to do this. The DPYD gene is one of the genes that tell your body how to use chemotherapy drugs. Some people have changes in their DPYD gene that can make their side effects from chemotherapy worse, sometimes so bad that they die. DPYD testing can tell doctors which people have these gene changes and need extra monitoring during chemotherapy. Some of the people in this study will join a focus group and read sample messages for future patients. They will discuss with the other participants how well the message does its job and anything that might make the message better. When there are no more messages, the host may ask about other information for future patients like a website or brochure. Other people in the study will read sample messages that may be sent to future patients about DPYD testing. They will select the message that they like the best and might make them ask their oncologist about testing options.

Sub-optimal transfer of clinical information during inter-hospital transfer (IHT, the transfer of patients between acute care hospitals) is common and can lead to patient harm. To address this problem, the investigators will use key stakeholder input to refine and implement an interoperable health information exchange platform that integrates with the electronic health record and improves the reliability of and access to necessary clinical information in three use cases involving transfer of patients between sending and receiving hospitals with varying levels of affiliation and health record integration. The investigators will assess the effect of this intervention on frequency of medical errors, evaluate the use and usability of this platform from the perspective of those that interact with it, and use these results to develop a dissemination plan to spread implementation and use of this platform across other similar institutions.

Oat Fiber for Digestive Health

Los Angeles, California
The goal of this interventional study is to evaluate the tolerability and potential health benefits of oat fiber oligosaccharide (BG-OS) in healthy adults aged 18-70 years. The main questions it aims to answer are: * Does oat fiber dose impact gastrointestinal tolerability, as assessed by changes in symptoms using the Gastrointestinal Symptom Rating Scale (GSRS)? * Does oat fiber reduce postprandial glucose levels after a white rice challenge? Researchers will compare three groups receiving different doses of oat fiber (5 g, 10 g, and 20 g) to assess dose-related effects. Participants will: * Complete daily surveys on gastrointestinal symptoms, diet, energy, and sleep quality. * Use a continuous glucose monitoring device (CGM) to track glucose levels throughout the study. * Participate in standardized white rice challenge tests to measure glucose uptake during baseline and at one time point during study. * Provide stool samples during baseline and at the end of the study for gut microbiota analysis. * Undergo blood tests for biomarkers like CBC, CMP, and A1C at the beginning and end of the study.

The goal of this pilot study is to examine the feasibility and effects of an 18-month intervention diet compared to an active control diet (standard diet) in those living with Parkinson's Disease (PD), without dementia. Research has shown that eating components of Mediterranean diets are associated with a 30% lower risk to develop PD and a 40% lower mortality rate in those living with PD. Diet may influence the gut and microbiomes, thus may affect PD risk and progression. This study will examine how easy it will be to adhere to a certain type of diet for 18 months and what changes may occur in the gut microbiome and in PD symptoms on a specific diet during that time. The study will involve in-person study visits at UBC as well as online diet coaching sessions and online group cooking classes over Zoom. This is a randomized study, meaning that participants will be assigned by chance to either the Mediterranean-style diet group or the standard diet group for the duration of the 18 months. This pilot study will also examine recruitment rates and retention, in order to prepare for a larger future study.

The purpose of this study is to determine if adding dietary fiber, such as inulin, to a diet that does not have enough fiber would raise the levels of potentially beneficial bacteria, such as Bifidobacterium, in the gut. There is evidence to suggest that these microbes can affect gut health and immune response, including to vaccines. The investigators will examine how inulin in the diet (compared to the maltodextrin control) (1) causes changes in the composition and function of the gut microbes, (2) reduces gut inflammation and gut leakiness caused by the vaccine, (3) increases immune response to vaccination, and (4) changes the expression of important adhesion molecules on the surface of white blood cells. Intestinal and whole-body responses will be measured in all participants.

"I was diagnosed with stage 4 pancreatic cancer three months ago, metastatic to my liver, and I have been receiving and responding well to chemotherapy. My blood work revealed that my tumor markers have gone from 2600 in the beginning to 173 as of now, even with the delay in treatment, they are not going up. CT Scans reveal they have been shrinking as well. However, chemo is seriously deteriorating my body. I have 4 more treatments to go in this 12 treatment cycle. I am just interested in learning about my other options, if any are available to me."

Frequently Asked Questions

How much do Gastrointestinal Health clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Gastrointestinal Health clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Gastrointestinal Health trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Gastrointestinal Health is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Gastrointestinal Health medical study?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Gastrointestinal Health clinical trials?

Most recently, we added Resistant Potato Starch for Gut Bacteria, Health and Wellness Products for Gut Health and Digestive Enzymes for Indigestion to the Power online platform.
