Chronic thoracic (mid-back) pain can be difficult to treat, and there is limited evidence to guide the use of injection therapies for pain arising from muscles and surrounding soft tissues. Two commonly used treatments are trigger point injections (TPI) and erector spinae plane (ESP) blocks, but no studies have directly compared their effectiveness for chronic thoracic myofascial pain. The purpose of this study is to compare pain relief, physical function, emotional well-being, patient satisfaction, and safety following treatment with either an ESP block or TPI. Participants will be randomly assigned to receive one of the two treatments. Researchers will follow participants for up to 12 weeks after the procedure and collect information through questionnaires and pain assessments.

Adults with Down syndrome (Ds) are often thought to have a lower risk of heart and blood vessel disease because they tend to have lower blood pressure and fewer heart attacks than people without Ds. However, recent research suggests that heart and blood vessel diseases, including stroke, are becoming a more common cause of death in adults with Ds as life expectancy increases. Despite these findings, studies examining heart and blood vessel health in adults with Ds have produced mixed results, making it difficult to determine their true risk and whether preventive strategies are needed. This study will investigate the health of blood vessels in adults with Ds and compare the results with those of adults without Ds. Healthy blood vessels are important because they help deliver blood and oxygen throughout the body. Changes in blood vessel function and stiffness can occur with aging and may increase the risk of heart disease, stroke, kidney disease, and memory problems. The study aims to determine whether adults with Ds experience changes in blood vessel health that may place them at increased cardiovascular risk. Specifically, the study will: (1) Examine how well blood vessels function in adults with Ds; (2) Measure the stiffness of arteries in adults with Ds; (3) Compare two methods used to assess blood vessel function to determine whether a simpler exercise-based test provides results similar to a commonly used standard test. The findings may improve understanding of cardiovascular risk in adults with Ds and help guide future strategies to promote healthy aging in this population.

The goal of this clinical trial is to learn if the Flo Digital Contraceptive (FDC) app can effectively prevent unintended pregnancy in women aged 18 years and older residing in the United States. The main questions it aims to answer are: What is the rate of unintended pregnancy in women aged 18-35 years using FDC as their sole method of contraception under typical-use conditions, measured using the Pearl Index? What is the cumulative probability of unintended pregnancy over 13 menstrual cycles for all participants, including those with regular and irregular cycles? Participants will: Use the Flo Digital Contraceptive app in 'prevent pregnancy' mode as their primary method of contraception for up to 13 menstrual cycles or 18 months, whichever comes first Wear an Apple Watch (Series 8 or later, or Ultra) while sleeping to collect nightly wrist temperature data, which the app uses to detect ovulation Log menstrual cycles, sexual activity, and any use of emergency contraception directly in the Flo app Complete monthly electronic surveys (ePROs) administered by the study team covering pregnancy status, adherence, safety, and experience Complete a baseline demographic survey at enrollment and an exit survey at the end of participation

Systemic lupus erythematosus (SLE) is a chronic, systemic autoimmune disease characterized by B cell hyperactivity. Rheumatoid Arthritis (RA) is a chronic inflammatory disease causing pain, stiffness, swelling and loss of joint function. The purpose of this study is to assess the pharmacokinetics, pharmacodynamics and safety of ABBV-519 in adult participants with SLE or RA. This is a single ascending dose study in an estimated 30 adult participants with moderate SLE or RA. The total duration of the study will be approximately 425 days (60-day Screening Period, 1-day Treatment Period, and a 52 week Follow-up Period) at approximately 15 to 20 sites globally. There may be higher treatment burden for participants in this trial compared to their standard of care (due to study procedures). Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

This study aims to provide mechanistic insights into how group drumming as a music-based intervention (MBI) affects pain responses and nociceptive function in individuals with Alzheimer's Disease (AD), mild dementia or mild cognitive impairment (MCI). Heart rate (HR), heart rate variability (HRV), and brain activity will be measured during communal drumming with their dyadic partners and others. Brain activity, blood pressure, cognitive abilities, blood hormone levels, and static and dynamic pain will also be measured during sessions pre and post the 8-week community drum circle. Investigators will leverage various measurement techniques including, but not limited to, electroencephalography (EEG), quantitative sensory testing (QST), behavioral, surveys, and physiological monitoring to study the impact of group drumming on pain and brain activity in AD and inter-dyad synchrony.

This phase II trial tests how well giving botensilimab and balstilimab prior or to surgery (neoadjuvent) works for the treatment of colorectal cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and that can be removed by surgery (resectable) colorectal cancer. Immunotherapy with monoclonal antibodies, such as botensilimab and balstilimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving botensilimab and balstilimab before surgery may make the tumor smaller. Giving neoadjuvant botensilimab and balstilimab may be effective for the treatment of advanced resectable colorectal cancer.

The goal of this clinical study is to evaluate the safety and preliminary efficacy of an investigational umbilical cord blood-derived stem cell and exosome infusion in adults with chronic lower back pain associated with degenerative spine disease. The primary questions this study aims to answer are whether the investigational infusion is safe and well tolerated and whether treatment may reduce pain and improve physical function and quality of life. Researchers will compare the investigational infusion to a placebo (saline solution) to evaluate potential treatment effects in participants with chronic mechanical lower back pain. Participants will receive either the investigational infusion or placebo intravenously during a study visit, complete pain, disability, and quality-of-life assessments, undergo magnetic resonance imaging (MRI) and laboratory testing, and attend follow-up evaluations over a 6-month period. Participants initially assigned to placebo may later receive the investigational treatment during an open-label crossover phase of the study.

This is a prospective, cross-sectional observational study designed to evaluate the Pediatric Sleep Questionnaire (PSQ) as a screening tool for sleep-disordered breathing (SDB) risk in a pediatric dental setting. Children aged 8-13 years will be classified as low- or high-risk for SDB based on PSQ scores and compared using physiologic sleep parameters obtained from a wearable, FDA-cleared home sleep monitoring device, alongside psychosocial assessments and craniofacial measurements derived from lateral cephalometric radiographs. Findings will inform the feasibility and accuracy of incorporating validated SDB screening into routine pediatric dental care.
