Alzheimer's disease (AD) is the most common cause of dementia. Despite major research efforts, effective treatments that slow or stop disease progression remain limited. Growing evidence suggests that inflammation in the brain and the body plays a key role in the onset and progression of AD. In particular, immune cells called regulatory T cells (Tregs), which normally help control inflammation, are impaired in AD individuals. This leads to increased activity of harmful immune pathways that worsen brain injury. Interleukin-2 (IL-2) is a drug that can restore the function of Tregs. Glucagon-like peptide-1 receptor agonists (GLP-1RAs), such as semaglutide, are a class of drugs currently used to treat diabetes and obesity. Beyond their metabolic effects, GLP-1RAs also reduce inflammation, protect brain cells, and improve cellular energy balance. Laboratory studies, including our own, show that combining IL-2 with semaglutide has stronger effects than either drug alone. Together, they enhance Treg function, dampen harmful inflammatory responses, and improve cell survival. These findings support testing IL-2 plus semaglutide as a novel combination therapy for AD. We now propose a clinical trial to evaluate the safety, feasibility, and biological effects of this strategy. The study will enroll 30 individuals with AD, ages 50 to 86, who have a confirmed diagnosis by amyloid PET brain imaging and a Mini-Mental State Exam score between 16 and 26. Participants will be randomly assigned to one of three groups: (1) placebo, (2) low-dose IL-2 alone, or (3) IL-2 combined with semaglutide. Throughout the trial, participants will undergo regular medical exams, blood tests, and safety monitoring. We will measure how the treatment affects Tregs and other immune cells, inflammatory markers in blood and CSF, and established Alzheimer's biomarkers such as amyloid beta, tau, and neurofilament light chain. Cognitive and functional assessments will also be conducted to explore potential benefits on memory and daily living skills. If successful, this study will provide the first evidence that a dual immunotherapeutic strategy can safely modify disease-related processes in AD. Such findings would lay the foundation for larger clinical trials and could open the door to a new, multimodal approach to slowing or preventing Alzheimer's progression.

This phase II trial compares standard of care surgical resection to fluorescence-guided surgical resection using indocyanine green and fluorescence imaging for reducing unexpected positive margin rates in patients with sarcoma. Surgical margins are one of the criteria used in assessing the effectiveness of a given surgical procedure. They are the edges or border of the tissue removed in cancer surgery. A negative margin means that the resected tumor is surrounded by normal tissue, which implies there is no disease left in the patient. By contrast, a positive margin means that sarcoma cells are visible at the edge of the tumor. Positive margins may be classified as planned when they are expected pre-operatively due to the preservation of a critical structure, or unexpected when the pathologist reports the presence of tumor at the margin despite the surgeon having intended to remove it in its entirety. Fluorescence-guided surgery is an established surgical method that involves the administration of fluorescent dye (in this case, indocyanine green) into the tumor, which can then be visualized with a special camera during surgery to help surgeons identify tumor versus healthy tissue. Fluorescence-guided surgery may reduce the rate of unexpected positive margins in patients undergoing surgery for sarcoma.

Systemic inflammation and intestinal hyperpermeability (disruption of the gut barrier which allows nutrient molecules and bacteria to enter the bloodstream) are triggered by consumption of high-sugar meals and are linked to future development of cardiovascular disease (CVD). Previous research indicates that fresh mangos have properties that have positive effects on the intestinal barrier and local gut inflammation. The investigators want to understand if replacing table sugar (sucrose) with sugar from fresh mango (which also contains fiber and plant bioactives) will lead to decreased inflammatory and permeability biomarkers after eating a high-sugar breakfast. The investigators will compare the postprandial (post meal) levels of inflammatory (IL-6) and permeability (LPS, lipid binding protein (LBP), and soluble CD14) biomarkers in blood from participants who have consumed a meal sweetened with either sucrose or fresh mango.

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 evaluate safety, effectiveness and durability of a gene therapy called Ixo-vec (Ixoberogene soroparvovec) when administered to the contralateral (second) eye of adult participants (≥ 50 years of age) who have been diagnosed with bilateral neovascular (wet) age related macular degeneration (nAMD). The study will enroll adults with nAMD in both eyes, including participants who previously received Ixo-vec treatment in one (initial) eye and/or participants who will receive Ixo-vec treatment for the first time. This study focuses on how the treatment works when both eyes are treated at different times and how effective and long-lasting Ixo-vec treatment is in the second (contralateral) eye. Participants will receive a single administration of Ixo-vec in the contralateral eye and will be followed for approximately 5 years to evaluate safety, efficacy and durability of contralateral treatment. Secondary objectives include assessments that will evaluate clinical activity, including visual and anatomic outcomes, as well as the need for supplemental anti-VEGF therapy. The study is intended to provide additional information on the safety, tolerability, and use of Ixo-vec in bilateral treatment.

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.
