The goal of this clinical trial is to study fecal microbiota transplantation(FMT) by oral capsule in people already diagnosed with auto-brewery syndrome (ABS, also known as gut fermentation syndrome). The main question it aims to answer: Is FMT safe and feasible in this syndrome? Participants will 1. have a "gut cleanout" with oral antibiotics and a colon cleanse, similar to that administered before colonoscopy 2. receive five oral doses of fecal transplant capsules over a week 3. be followed for six months for safety and research samples

The purpose of this study is to learn whether PYLARIFY PET imaging (study scan) can safely and accurately detect the presence or absence of prostate cancer growing beyond the prostate gland in men with favorable intermediate risk prostate cancer. Participants will receive a single dose of PYLARIFY injection followed by a single whole-body PET/CT or PET/MRI scan acquired at 1 to 2 hours after PYLARIFY injection. Participants with positive study scan results that are suspicious for prostate cancer outside of the prostate gland may be asked to undergo additional diagnostic test(s) and/or recommend certain treatment(s) for prostate cancer within 2 to 90 days after the study scan. Participants will be monitored for up to 12 months to collecting information about treatment they receive for prostate cancer and results of regular PSA blood draws if ordered by doctors for up to 12 months after the study scan.

The goal of this study is to test the effects of just-in-time intervention strategies aimed to promote implementation of the safety plan and its components at different levels of suicidal urges and intent. The main questions the investigators aim to answer are: 1. What is the acceptability and feasibility of the just-in-time intervention strategies? 2. What are the proximal effects of just-in-time intervention strategies aimed to promote use of the safety plan and its components? 3. What internal and external contextual factors moderate the just-in-time intervention effects? Participants (adults hospitalized for suicidal thoughts or behaviors) will: - Answer questions about current suicidal thoughts on their smartphone up to 4 times each day during both hospitalization and the 4 weeks after they leave the hospital - Each time they submit a survey, be immediately randomized to receive (or not receive) a just-in-time intervention tailored to their level of current suicidal thoughts - Answer brief follow-up questions on their smartphone within a couple hours of each randomization - Provide feedback on their experience with the just-in-time interventions

This is an open-label, FIH study designed to evaluate the maximum tolerated dose, recommended Phase 2 dose, safety, tolerability, PK, pharmacodynamics, and preliminary antineoplastic activity of RLY-2608, in advanced solid tumor patients with a Phosphatidylinositol-4,5-bisphosphate-3 kinase, catalytic subunit alpha (PIK3CA) mutation in blood and/or tumor per local assessment. The study will evaluate RLY-2608 as a single agent for patients with unresectable or metastatic solid tumors. It will also evaluate RLY-2608 in combination RLY-2608 + fulvestrant and in triple combination RLY-2608 + fulvestrant + CDK4/6 inhibitor (palbociclib or ribociclib) or CDK4 inhibitor (PF-07220060) for patients with HR+ HER2- locally advanced or metastatic breast cancer or endometrial cancer (palbociclib or ribociclib Part 1). The RLY-2608 single agent arm, RLY-2608 + fulvestrant combination arm, and triple combination arms will have 2 parts: a dose escalation (Part 1) and a dose expansion (Part 2).

This trial studies how well proton beam radiation therapy compared with intensity modulated photon radiotherapy works in treating patients with stage I-IVA esophageal cancer. Proton beam radiation therapy uses a beam of protons (rather than x-rays) to send radiation inside the body to the tumor without damaging much of the healthy tissue around it. Intensity modulated photon radiotherapy uses high-energy x-rays to deliver radiation directly to the tumor without damaging much of the healthy tissue around it. It is not yet known whether proton beam therapy or intensity modulated photon radiotherapy will work better in treating patients with esophageal cancer.

The main purpose of this study is to: - Learn about the safety of REGN4018 and to find out what dose of REGN4018 can be given alone or with cemiplimab to patients with ovarian cancer or cancer of the uterus - The study will also look at the levels of REGN4018 and/or cemiplimab in your body and measure how well your body can remove the study drug(s). This is called pharmacokinetics - The study will also look at any signs that REGN4018 alone or with cemiplimab can treat recurrent advanced ovarian cancer or cancer of the uterus - To find out how safe and tolerable the sarilumab pretreatment is, in combination with REGN4018 and cemiplimab

This is a Phase 1/2 open-label, multi-center, multi-national study with an initial dose escalation part to determine the recommended Phase II dose (RP2D) of MCLA-158 single agent in patients with mCRC. The dose escalation part has been completed and the RP2D will be further evaluated in an expansion part of the study. Cohorts of selected solid tumor indications for which there is evidence of EGFR dependency and potential sensitivity to EGFR inhibition will be evaluated including head and neck cancer and metastatic colorectal cancer (mCRC). The study will further assess the safety, tolerability, PK, PD, immunogenicity, and anti-tumor activity of MCLA-158 in monotherapy or in combination with other therapies.

Chronic intestinal hypoxia and accompanying mucosal inflammation is a hallmark of ulcerative colitis (UC). Hyperbaric oxygen therapy (HBOT) involves breathing 100% oxygen under increased atmospheric pressure to increase tissue oxygenation. Two small prospective randomized controlled trials have demonstrated that the delivery of HBOT to UC patients hospitalized for acute moderate to severe flares results in improved remission rates and avoidance of in-hospital progression to biologics, small molecules, or colectomy. In this larger trial the study aims to confirm the treatment benefits of HBOT for hospitalized UC patients and study the immune-microbe mechanisms underpinning treatment response.

The goal of this investigational study is to develop algorithms that predict human response to foods. The main question it aims to answer are: - How does varying foods and eating patterns impact one's biological and physiological responses? - In what ways can novel dietary assessment measures be used to improve dietary assessments and to prescribe assessments to people in future research with increased precision? - Can artificial intelligence and machine learning techniques be combined to prescribe foods and eating patterns to individuals for optimization of their health? There are 3 Modules participants may take part in: - Module 1- A participant's dietary intake and accompanying nutritional status, biological and other measures will be observed over 10 days, as well as physiological responses to a liquid mixed meal tolerance test will be measured. - Module 2- Participants will undergo three controlled dietary interventions provided for 14-days each and separated by washout periods of at least 14 days. Physiological responses following a diet-specific meal test will be measured. - Module 3- Participants will undergo the same three dietary interventions during the same 14 day periods as Module 2 while being studied in-residence. Physiological responses following a liquid mixed meal tolerance test and a diet-specific meal test will be measured.
