Mindful Walking Neural Correlates of Executive Function in SC Older Adults at Risk of Dementias
University of South Carolina Older Adults With Elevated Dementia Risk

Mindful walking is a promising and practical strategy because it combines two activities known to support healthy aging: walking and mindfulness. Unlike many structured exercise programs, mindful walking is low intensity, accessible, and easier to sustain in daily life. It may be especially useful for older adults at elevated risk for ADRD. However, most existing mindful walking studies have focused on mental health outcomes, such as stress reduction, rather than cognitive health. Little is known about whether mindful walking can support cognition or how it may influence brain function. To address this gap and strengthen a future R01 resubmission, the investigators propose a two-arm randomized controlled pilot trial using functional near-infrared spectroscopy (fNIRS), a safe, non-invasive brain imaging method. fNIRS measures brain activity through sensors placed on the scalp and is well-suited for repeated assessments in older adults because it is quiet, portable, painless, and cost-effective. The investigators will recruit racially and ethnically diverse middle-aged and older adults from the Midlands of South Carolina who are at elevated risk for ADRD. Participants will be randomly assigned to one of two groups: mindful walking or walking-only control. Both groups will complete 8 staff-supervised individual sessions over 4 weeks. The mindful walking group will learn and practice simple mindfulness skills while walking in multiple settings, including lab-based, indoor, and outdoor environments, to support real-world use. Findings from this pilot study will provide important evidence on whether mindful walking can support brain and cognitive health in adults at elevated risk for ADRD. The results will also help establish a practical, scalable, and sustainable prevention strategy for underserved aging populations in South Carolina.

The main reason for this research study is to understand whether the sleep habits of 11-12 years-olds impact their response to a vaccine. The vaccine is called MCV4. It protects against meningococcal illness, which is rare but can be severe. The American Academy of Pediatrics recommends that the vaccine be given at age 11 or 12. The vaccine has been approved for youth in this age range for over 20 years and is one of the vaccines that primary care doctors typically give around this age. However, nobody has studied how sleep affects children's response to it. This could be important because research on adults suggests that sleep affects the immune system. We want to look at that issue in a younger age range. Participating families will be asked to have their child keep their regular sleep schedule during the 5-week study, without much variation. During that time, they will wear a special wristwatch at night to track their sleep. Each day they will fill out a short online form. They and a parent/guardian will come to Cincinnati Children's twice. Each visit will last 1 - 1 ½ hours. The first visit will happen at the end of the 1st week. The second is at the end of the 5th week. During visits, they will fill out forms and we will get data from the wristwatch. During the first visit, the participating child would get the vaccine. During the second, they will have a blood test.

Narcolepsy is a sleep disorder that disrupts a person's regular sleep-wake cycle. It causes extreme sleepiness during the day (called excessive daytime sleepiness [EDS]), where a person may fall asleep without warning. Narcolepsy Type 1 (NT1) is a form of the condition in which people also have sudden, unexpected muscle weakness while staying conscious (called cataplexy). The main aim of this study is to learn how safe TAK-360 is and how well adults with NT1 tolerate it. Adults who can participate in the study will have to stop taking their existing medicines for NT1 before study treatment starts. Participants may be randomly (by chance, like drawing names from a hat) assigned to get either TAK-360 or placebo during the treatment period. The placebo looks just like TAK-360 but does not have any medicine in it. After the treatment period, participants can be monitored for another 2 weeks. Participants can restart their usual NT1 treatment after study treatment ends. The participants will have to visit the clinic multiple times during this study.

The purpose of this study is to learn about the safety of a new pneumococcal vaccine and how the new pneumococcal vaccine helps to fight against germs that can cause pneumonia (lung infections), meningitis (brain infections), and otitis media (ear infections) in infants when compared to the pneumococcal vaccine that is currently in use, 20vPnC (Prevnar 20®). This study will test if the new pneumococcal vaccine is as safe as the one that is currently in use. It will also assess how the new vaccine works in comparison to the one that is currently in use when given with other childhood vaccines. To measure how the new pneumococcal vaccine compares to the current one, blood samples will be used to measure the body's ability to create proteins to fight those germs. This new vaccine can possibly provide additional protection against germs that cause pneumococcal disease that are not included in the vaccines that are currently given to infants. Pneumococcal disease includes a variety of infections caused by a specific germ, Streptococcus pneumoniae. There are three groups in this study. All participants will be assigned to one of the three groups. This study is seeking participants who are: - infants who are 2 months of age in Group 1; - infants who are 2 to 6 months of age in Groups 2 and 3; and - said to be healthy by the study doctor About 3000 infants will be assigned to Group 1. The infants in this group will have a 1 in 2 chance (50%) of receiving either PG4 (new vaccine) or 20vPnC (currently in use) into the left thigh muscle at 2, 4, 6, and 12 to 15 months of age. About 140 infants from outside the United States will be assigned to Group 2. The infants in this group will have a 1 in 2 chance (50%) of receiving either PG4 or 20vPnC into the left thigh muscle at 2 to 6, 3 to 8, 4 to 10, and 12 to 15 months of age. About 90 infants from outside the United States will be assigned to Group 3. The infants in Group 3 will have a 1 in 3 chance (33%) of receiving either PG4 into the left thigh muscle, PG4 under the skin of the left thigh, or 20vPnC into the left thigh muscle at 2 to 6, 3 to 8, 4 to 10, and 12 to 15 months of age. Infants in Group 1 will take part in this study for about 16 to 19 months (about 1 and a half years). Infants in Groups 2 and 3 will take part in this study for 12 to 21 months (about 1 to 1 and a half years). During this time, infants will have 6 study clinic visits and 1 phone call. At these study clinic visits, parent(s)/legal guardian(s) will be asked if the infant experienced any side effects. A side effect is an unintentional or unexpected reaction to a vaccine. Infants will have 3 blood samples collected.

The purpose of this study is to learn about the potential benefits of two different training programs in helping improve emotional health and well-being in people who have had a traumatic brain injury. Participants will be assigned to one of two programs based on the time since their injury. One of the programs will teach participants how to recognize and label emotions; the other will teach healthy ways of living. Participants may improve their emotional well-being and contribute to the knowledge needed to achieve better emotional health outcomes for people with TBI. For eligible participants, the study includes 4 assessments. Assessments may take 30-60 minutes and will be done using secure videoconferencing, phone calls, and/or electronic surveys. The first assessment will ask questions about demographics, the participant's brain injury, and some medical history. All assessments will include questions about emotions, emotional awareness, resilience, loneliness, and how participants manage emotions, in addition to broader wellness questions and questions about how participants interact with others. Regardless of the program, the training includes 8 one-on-one sessions with a trained staff member over the course of about 1 month. Each session will last approximately 60-90 minutes. These sessions will start shortly after completing the first assessment. Preferably, participants will complete 1-2 training sessions a week, depending on availability and preference. These sessions will include education, discussion, and practice exercises. After the program is finished, participants will be asked to complete the same surveys completed at baseline for three follow-up time points (immediately following the program, 3 months after the program, and 6 months after). Total participation in the study will last approximately 8 months.

The goal of this behavioral interventional trial is to determine how best to communicate personalized cardiovascular risk information and support behavior change among participants enrolled in the Dallas Heart Study (DHS) cohort. The main questions it aims to answer are: - What are the effects of presenting health information in a coarse vs. granular manner? (This question will be measured by randomizing participants to two groups: one group will get a cover letter with their health information communicated in a more detailed manner, while another group will receive a cover letter which presents their health information in a coarse manner. Two letters will be sent containing the same information regarding their results. 4 months after the second letter, participants will be asked about changes made for their health after receiving the letter) - How curious are people about bettering their health after being presented their health information? (This question will be measured by placing QR codes linking educational health videos on each cover letter. Each letter will be sent twice with exactly the same health information but with new QR (Quick Response) codes. QR code use will be tracked by the study staff) Researchers will assess whether participants who received different style letters had different responses to their health behaviors and medication afterward and will measure this with a follow-up phone call. Researchers will also assess the use of QR codes showing health-related videos (about physical activity, heart-healthy diet, diabetes medication, statin medication) by sending out two different letters with the same health information and format, but with different QR code-linked videos. Participants will: - Receive two letters in the mail, 4 weeks apart, containing their results from the Dallas Heart Study's 4th visit. The cover letter for this report will be randomized and will contain coarse vs. granular presentations of the participant's heart health risk. - Receive a follow up call after 4 months to assess: whether they received the letter, whether they understood the information provided, whether they made any health changes after receiving the letter, whether they saw a healthcare provider after receiving the letter, whether the letter prompted a new diagnosis by a doctor, and whether the participant made any medication changes after the letter.
