Brain Stimulation for Stress

Pittsburgh, Pennsylvania
Investigators are conducting this study to test if temporarily and non-invasively stimulating the brain will affect the emotional response to stress in healthy participants. Participants will perform a series of tasks while completing an MRI scan. After this, participants will be randomized to undergo transcranial magnetic stimulation (TMS) at two visits, undergoing active stimulation at one visit and undergoing 'sham' stimulation at another visit. Immediately following both stimulation sessions, participants will repeat the tasks during MRI scanning.

The purpose of this study is to find out if investigators can stimulate the vagus nerve (a nerve in the body that runs from your brain to the large intestine), and influence insulin, C-peptide, and glucose levels. C-peptide is a substance that is created when insulin is produced and released into the body. The vagus nerve is a largely internal nerve that controls many bodily functions, including stomach function. Investigators hope that by stimulating the vagal nerve using the TeNS behind the ear, this stimulation can affect insulin levels, and this will help innovate treatment of patients with nausea, vomiting, and disordered stomach function, and patients with diabetes. Researchers hope to be able to measure the activity of the vagus nerve when it is stimulated in other ways. This could help investigators learn more about studying this nerve in the future.

Neuromodulation is a fast growing field that offers a wide range of applications for both understanding and treating the brain. Future research for non-invasive neuromodulation will need to elucidate the optimal frequency, duration, and intensity of stimulation for a variety of technologies and diseases. Closed loop stimulation is thus a promising research area that allows for responsive stimulation and real time symptom management. Our project is proposed to develop and test a novel noninvasive neuromodulation integrating transcranial focused ultrasound stimulation (tFUS) with electrophysiological source imaging (ESI-tFUS) to allow evidence-based neuromodulation for brain research and the management of brain conditions. Despite the recent developments and attention surrounding tFUS, relatively little is known about the mechanisms and optimal parameters of this stimulation technology. The addition of ESI neuroimaging, aimed at providing biomarkers to assess the effects of tFUS neuromodulation, could provide crucial necessary information regarding the neural response to the applied stimulation in real-time. In order for tFUS to be further developed and transformed into a robust neuromodulation technology, an integrated electrophysiological source-imaging-guided tFUS system to allow for individualized and responsive stimulation is needed. The purpose of this study is to develop and evaluate the proposed ESI-tFUS in human subjects using motor and somatosensory paradigms.

The goal of this study is to evaluate the effectiveness of a mind-body medicine training program on parole services staff. The main questions it aims to answer are: * Will participation in the training increase resilience; empathy; the belief that one can cope with difficult situations; and decrease symptoms of depression, stress, anxiety, and burnout? * What is the personal and professional impact of the training program? Sixty staff members of the Indiana Department of Correction Parole Services Division will do the following: * Attend an initial 4-day mind-body medicine training. Mind-body techniques taught in the training include: meditation; a breathing exercise; biofeedback; guided imagery; expressing oneself through drawings and writing; movement to reduce stress; and family trees to explore family dynamics. * Attend a 2-day practicum. The 2-day practicum will teach staff the ways in which they can share the skills they have learned one-on-one with parolees and families of parolees. * Attend 4 biweekly sessions of 2-hour group consultation sessions. The consultations will support the use of the mind-body skills with the parolees. Participants will also do the following: * Fill out standardized questionnaires online before and after the training program in order to measure changes in resilience; empathy; the belief that one can cope with difficult situations; and symptoms of depression, stress, anxiety, and burnout. * Fill out an additional online questionnaire three months after the consultation sessions to determine how trainees are using the mind-body skills in their work. * Participate in an online group interview to determine how trainees are using the skills and how the training has affected them personally and professionally.

Lorazepam for Psychosis

Ann Arbor, Michigan
The purpose of this study is to better understand mental illness and will test the hypotheses that while viewing affective stimuli, patient groups will show increased blood oxygenation level dependent (BOLD) signal by fMRI after lorazepam. This study will enroll participants between the ages of 16 and 60, who have a psychotic illness (such as psychosis which includes conditions like schizophrenia, schizoaffective disorder, and mood disorders). The study will also enroll eligible participants without any psychiatric illness, to compare their brains. The study will require participants to have 3-4 sessions over a few weeks. The initial assessments (may be over two visits) will include a diagnostic interview and several questionnaires (qols) to assess eligibility. Subsequently, there will will be two separate functional magnetic resonance imaging (fMRI) sessions in which lorazepam or placebo will be given prior to the MRI. During the fMRI the participants will also be asked to answer questions. Additionally, the participants will have their blood drawn, women of child bearing potential will have a urine pregnancy test, vital signs taken, and asked to complete more qols.

The vagus nerve is a largely-internal nerve that controls many bodily functions, including stomach function. Investigators hope that electrically stimulating the nerve around the external ear will also stimulate the internal vagus nerve. If it does, then investigators hope that this will help the treatment of patients with nausea and vomiting and disordered stomach function. Investigators also hope to be able to measure the activity of the vagus nerve when it is stimulated in other ways. This could help investigators learn more about studying this nerve in the future.

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 importance of the gut microbiota for general health has been recently elucidated, but little is known about the impact of different types of nutrients on the gut microbiota. The soluble fiber in cereal by-products, arabinoxylan (AX), is known to be beneficial for generally promoting gut health. However, it is unclear whether consuming rice bran (RB), the source of AX, is equally helpful or better than consuming the extracted form of AX. This study aims to reveal the potential benefit of insoluble cereal bran fiber ingredients by comparing the effect of soluble arabinoxylan fiber alone and the mostly insoluble rice bran fiber, containing arabinoxylan, on intestinal health and gut microbiota. A placebo (maltodextrin) will be used as a control, with no significant changes expected in this group for the evaluated outcomes. Participants will: * Consume two different fiber supplements (soluble arabinoxylan or stabilized rice bran) as well as a placebo (maltodextrin) for 3 weeks each, separated by a 2-week washout period. * Provide blood and stool samples at six different time points. * Complete a food and gastrointestinal symptom diary during the intervention periods.

Inulin for Healthy Subjects

West Lafayette, Indiana
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.

Frequently Asked Questions

How much do Healthy Subjects 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 Healthy Subjects 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 Healthy Subjects 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 Healthy Subjects 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 Healthy Subjects 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 Healthy Subjects clinical trials?

Most recently, we added Barley Lysine Availability for Healthy Subjects, Citrate for Kidney Stones and TEA Device Usability and Safety Study to the Power online platform.
