The goal of this observational study is to evaluate the levels of urinary environmental toxins, heavy metals, PFAS and mycotoxins with gastrointestinal (GI) and overall health.
The objective of this study is to investigate the survival of Lacticaseibacillus paracasei strain Shirota (LcS) in the human gastrointestinal (GI) tract after consumption of probiotics fermented milk product containing 8x10\^9 LcS. This study is a single-arm, open-label study with a 14-d run-in (baseline), 14-d consumption period, and 14-d follow-up. Participants will maintain habitual dietary and lifestyle practices with the exception of avoiding fermented foods and beverages throughout the 42-d trial. The number of live LcS in fecal samples will be assessed after 14 d consumption of a fermented milk product.
The purpose of this study is to characterize the way the first commercially available integrase inhibitor, raltegravir, a new class of antiretrovirals that is used to treat HIV, is distributed into the rectal mucosal tissue. This information will generate important information regarding the drug's penetration into lymphoid tissues that are rapidly depleted in HIV infection. Subsequently strategies to prevent the sexual transmission of HIV and for treating HIV-infected individuals will be designed.
This is a single-center, randomized, double blind, placebo-controlled study evaluating the effects of placebo, codeine, methylnaltrexone and codeine with methylnaltrexone on gastrointestinal motility and colonic transit of solids in healthy human subjects. The hypotheses are: 1. Methylnaltrexone administered subcutaneously enhances gastrointestinal motility with acceleration of overall colonic transit, and ascending colon emptying of solids in healthy humans. 2. Methylnaltrexone significantly accelerates colonic transit that is delayed by codeine
This study is designed to evaluate the safety and immunogenicity of two monovalent Norovirus (NoV) oral tableted vaccine candidates, VXA-G1.1-NN and VXA-GII.4-NS co-administered (bivalent delivery) against a matching placebo arm. Bivalent GI.1 and GII.4 vaccines are being investigated for the prevention of noroviral gastroenteritis caused by norovirus GI.1 and GII.4.
The primary goal of this protocol is to conduct an open pilot to collect initial quantitative and qualitative feedback on the intervention that the investigators are developing. To do so, the investigators will deliver a newly-developed intervention to up to 2 consecutive groups of female colorectal and anal cancer survivors (n = up to 10 per group, total N = up to 20). Participants will provide feedback regarding intervention acceptability, feasibility, and perceived benefit. To inform plans for ongoing program refinement, the investigators will elicit specific feedback about study assessment tools, recruitment procedures, and group factors. Given the early-stage, open pilot nature of this protocol, the investigators will not set strict criteria to establish feasibility and acceptability but will rather interpret each of these outcomes holistically. Qualitative feedback collected in post-intervention exit interviews will also support understanding of feasibility and acceptability. As a secondary aim, the investigators will explore the preliminary effects of the intervention on psychosocial measures of satisfaction with sexuality and impact of functional limitations, coping abilities, acceptance of body image changes, loneliness, and anticipated stigma. As noted above, the investigators will not set specific criteria to establish preliminary efficacy, nor will they consider statistical significance as an indicator of the study's efficacy for these outcomes. Instead, the investigators will consider pre-post intervention effect sizes to consider the need for refinement of study procedures/measurement in a future larger trial. In future, larger-scale, work, the investigators intend to conduct a larger randomized pilot trial to assess intervention acceptability, feasibility, as well as preliminary efficacy on essential outcomes related to sexual well-being.
Gastroparesis Patients and Healthy Controls ages 20-49 will be asked to participate in an observational study measuring vagal activity following food ingestion in order to establish parameters of autonomic nerve/vagal function in healthy human subjects compared to those with gastroparesis. Information generated from this study may be used in the future to establish what is normal and abnormal enteric vagal tone and how much vagal nerve stimulation treatment may be required to help patients with gastroparesis.
A positive impact of a fermented dairy protein with prebiotic fiber supplement on self-reported GI complaints and wellbeing has been suggested (Wardenaar et al. 2024). The following project aims to further investigate the impact of this supplements in athletes with and without GI complaints in two separate data collections. Part I of the data collection aims to investigate the impact of this supplement vs. a placebo on carbohydrate malabsorption (as a potential cause for GI distress) in athletes that normally don't identify as having GI complaints (randomized double-blind cross over study design covering a total of 9 weeks, including a 3-week washout period). Part II of the data collection aims to confirm the earlier found results in the previous study (Wardenaar et al. 2024) in a group athletes self-reporting GI complaints that will be randomized into an intervention group or a placebo group (randomized double-blind parallel study design covering a total of 3 weeks).
This clinical trial evaluates a clinic-wide intervention called Primary Care-Gastrointestinal (GI) Connect for improving follow-up colonoscopy rates in patients at a Federally Qualified Health Center (FQHC) who have an abnormal fecal immunochemical test (FIT) result. Colorectal cancer screening reduces colorectal cancer incidence and mortality but is underutilized.The most accessible, feasible, and common colorectal cancer screening modality for average-risk individuals in low resource settings such as FQHCs is the stool-based FIT. However, the benefit of FIT screening on colorectal cancer risk is realized only if individuals with abnormal FIT results undergo timely follow-up colonoscopy. Follow-up colonoscopy rates are low and there are many barriers to follow-up colonoscopy in safety net settings such as FQHCs. Effective interventions that are multi-component and improve care coordination are needed to improve abnormal FIT follow-up rates in FQHCs. The Primary Care-GI Connect intervention includes components that enhance care coordination, standardize the referral process, and engage both primary care and specialist physicians. This clinic-wide intervention may improve rates of follow-up colonoscopy after abnormal FIT results in patients seen at FQHCs.
Soluble corn fiber (SCF) has been shown to enhance calcium utilization and bone properties in rats and in adolescent boys and girls.
