Healthy Paid Clinical Trials in Indiana

Acute urethritis (inflammation of the male urethra) affects millions of men in the United States each year. Effective management of STIs is complicated by asymptomatic infections, as men often delay seeking care until symptoms become severe. Yet, even men without symptoms can show measurable evidence of urethritis. Therefore, a cheap, simple, and non-invasive point-of-care (POC) test, providing results within 30 minutes, could significantly enhance STI management by facilitating early diagnosis and treatment. A new diagnostic method, urine flow cytometry, has shown potential in hospital settings for accurately detecting inflammation by counting white blood cells (infection-fighting cells) in urine samples. The Sysmex UF-5000 flow cytometer, a state-of-the-art device, may offer a non-invasive, cost-effective, and accurate method to diagnose urethritis compared to traditional Gram stains and urinalysis, potentially extending its use beyond specialized clinics. This study aims to determine the efficacy and precision of the Sysmex UF-5000 analyzer in diagnosing urethritis using first-catch urine samples. Additionally, the study seeks to evaluate whether urine collected using the 10 mL Colli-Pee device provides greater accuracy and precision compared to the standard urine cup (30-60 mL) when used with urine flow cytometry and LE urinalysis.

The goal of this randomized controlled trial is to learn about the effect of a 12-week school-based intervention combining mindfulness with high-intensity interval training (MF-HIIT), MF-only intervention, and HIIT-only intervention in relative to sedentary activities on executive function (EF) in 8-12 years old children. The main question it aims to answer is whether a 12-week school-based MF-HIIT intervention has larger beneficial effect on EF performance than that following a 12-week school-based MF-only and HIIT-only in relative to the sedentary activities. Multiple cohorts of participants will be recruited to participate this one-semester study, including the pretest, intervention, and posttest phases. During the pretest phase, participants an their parents will complete the following 1. Kaufman Brief Intelligence Test (KBIT) to assess intelligence quotient 2. Fitnessgram test to assess aerobic capacity, muscle endurance, flexibility, and body mass index 3. Child and Adolescent Mindfulness Measure (CAMM) questionnaire to assess dispositional mindfulness 4. Computerized tasks to assess EF 5. Parent-reported demographic and health information Following the pretest phase, participants will receive the 12-week classroom-based intervention, with the classroom as the intervention unit. Following the intervention and during the posttest phase, participants will complete the fitness, measures, EF measures, and dispositional mindfulness measure again. Researcher will compare the EFn outcome measures following the MF-HIIT, MF-only, and HIIT-only interventions with the sedentary activity intervention to see if MF and HIIT has beneficial effects on children's EF. Further, researcher will compare the EF measures following the MF-HIIT compared with MF-only and HIIT-only interventions to see if combining MF with HIIT has greater beneficial effects on children's EF than MF and HIIT alone.

The goal of this randomized cross-over trial is to learn about the effect of a single bout of 20-min mindfulness-based high-intensity interval training (MF-HIIT), MF-only, and HIIT-only in relative to sitting rest on executive function (EF) in 10-12 years old children. The main question it aims to answer are: Question 1: Whether a single bout of 20-min MF-HIIT has larger beneficial effect on EF performance than that following a 20-min session of MF-only and HIIT-only in relative to the sitting rest Question 2: Whether a single bout of 20-min MF-HIIT has a larger beneficial effect on brain functioning, as measured by the N2 and P3 components of event-related potential (ER) during EF performance than that following a 20-min session of MF-only and HIIT-only in relative to the sitting rest Participants will visit the laboratory on 5 separate days (\> 2-day washout between days) in which they have not previously participated in structured physical activities. Participants will complete the testing and/or receive treatments below: Day 1: * Kaufman Brief Intelligence Test (KBIT) to assess intelligence quotient * Treadmill-based exercise test to measure cardiorespiratory fitness (maximum oxygen consumption) Days 2-5 * Each day, participants will complete each of the four intervention conditions (MF-HIIT, MF-only, HIIT-only, sitting) * Participants' heart rate and self-reported affect and rating of physical exertion will be measured * Participants will complete a modified flanker task and a task-switching task to assess inhibitory control and cognitive flexibility * Participants will wear an EEG cap to measure the N2 and P3 components of the event-related potential during the inhibitory control and cognitive flexibility performance Researcher will compare the cognitive outcome measures following the MF-HIIT, MF-only, and HIIT-only conditions with the sitting condition to see if MF and HIIT has beneficial effects on children's EF. Further, researcher will compare the cognitive outcome measures following the MF-HIIT compared with MF-only and HIIT-only conditions to see if combining MF with HIIT has greater beneficial effects on children's EF than MF and HIIT alone.

The iCaRe2 is a multi-institutional resource created and maintained by the Fred \& Pamela Buffett Cancer Center to collect and manage standardized, multi-dimensional, longitudinal data and biospecimens on consented adult cancer patients, high-risk individuals, and normal controls. The distinct characteristic of the iCaRe2 is its geographical coverage, with a significant percentage of small and rural hospitals and cancer centers. The iCaRe2 advances comprehensive studies of risk factors of cancer development and progression and enables the design of novel strategies for prevention, screening, early detection and personalized treatment of cancer. Centers with expertise in cancer epidemiology, genetics, biology, early detection, and patient care can collaborate by using the iCaRe2 as a platform for cohort and population studies. Read Less

The main aim of this study is to investigate differences in rate, extent of change and persistence of the gut microbiota in healthy adult volunteers in response to native chicory inulin. Along with investigating the impact of native chicory on bowl habits, mood and appetite. The two main questions this study aims to answer: * To what extent do differences exist in rate of change over time between individuals in gut microbiota response (Bifidobacterium growth) to native chicory inulin supplementation. * To what extent do differences exist between individuals in persistence of the gut microbiota upon stopping supplementation. The effects of native chicory inulin on gut microbiota response will be compared to a maltodextrin placebo to sure changes in gut microbiota result directly from chicory inulin supplementation. Participants will firstly complete a one-week run-in phase to establish baseline data and will then be allocated to either native chicory inulin or maltodextrin supplementation for 6 weeks. Inulin will be delivered at 12 g/day split into 2 x 6g portions. Maltodextrin will be calorie matched at 6 g/day split into 2 x 3g portions. This will then be followed by a 6 week post-supplementation phase. Fecal and blood samples will be collected regularly throughout all phases for analysis of gut microbiota and compounds of interest. Participants will also record any changes in gastrointestinal sensation, bowel habits and mood in a diary. Changes in appetite sensation will also measured. Read Less

Food insecurity and low diet quality are persistent problems linked with chronic disease and poor health among limited-resource children and adults using Supplemental Nutrition Assistance Program (SNAP). We have shown nutrition education via adult-focused, direct SNAP-Education (SNAP-Ed) improved household food security by 25% but not adult dietary quality among SNAP-eligible households using a randomized, controlled, longitudinal SNAP-Ed intervention in Indiana. Households experiencing food insecurity often reserve food considered "healthful" for children, so child dietary quality improvement may precede that observed among adults when household food security improves. This study will determine the effect of adult-focused direct SNAP-Ed on child dietary quality and household food security using a longitudinal randomized, controlled SNAP-Ed intervention. Assessment will include repeated 24-hour dietary recalls to determine usual intake, the U.S. Household Food Security Survey Module, and behavior data from before and after the 10-week "intervention period," and 1 year later, after which the control group will receive the intervention. Low-income participants (n=275) from Indiana will be recruited following SNAP-Ed protocol. Results of the study will inform the creation of supplementary on-demand SNAP-Ed educational material focused on improving healthful dietary intake for children and adults in situations of food insecurity in households with children. Education on modeling healthy attitudes and behaviors, planning and preparing family meals, and dietary shortfalls as informed by the results and previous evidence will be included and evaluated. The study aligns with the goals of USDA to increase food security and this RFP to improve healthful behaviors, food quality and nutrition. Read Less
