The Use of a Comfort Tote to Improve Recovery in Pediatric and Adolescent Patients After Surgery

The goal of this clinical trial is to learn if the use of Comfort Tote can treat pain and anxiety in adolescents with idiopathic scoliosis undergoing posterior spinal fusion. The study aims to answer two questions: 1. To characterize the effectiveness and determine the impact of integrative therapy interventions of the Comfort Tote use in reducing self-reported pain, anxiety, and stress among pediatric patients with AIS undergoing PSF. By comparing self-reported pain, anxiety, and stress scores, as well as documented Morphine Milligram Equivalents (MMEs) and Numeric Rating Scale (NRS) pain scores, between patients using non-therapeutic and therapeutic Comfort Totes. 2. To evaluate the impact of an educational video on the use of the Comfort Tote. This will assess whether the inclusion of instructional content enhances understanding and application of the Comfort Tote, thereby improving patient outcomes in pain management, anxiety reduction, and overall satisfaction with care. It is hypothesized that the therapeutic Comfort Tote intervention with the educational video will provide the highest patient satisfaction and greater tote usage, with decreased patient pain, stress, and anxiety levels. The findings from this pilot study will provide crucial insights into establishing a new standard of care for pediatric patients undergoing PSF and potentially provide baseline data for use in larger, multicenter randomized controlled trials.

Effects of Ultra Processed Food on Intestinal Energy Harvest

Ultra processed food is everywhere in modern society and may contain multiple ingredients that affect the way participants' bodies store energy. Some studies have shown that eating a diet high in ultra processed foods leads to weight gain, but these foods have not been studied enough to understand why. Recently, the gut microbiome has become a potential way to measure energy balance in the human body; this is done by measuring how many calories are in the stool. The investigators propose to test a very high ultra-processed food diet where 80% of calories are coming from ultra processed food and a low ultra processed food diet where 20% of the calories are coming from ultra processed food. This study will compare stool sample energy content of the two diets.

Migraine Headaches Elimination With Patent Foramen Ovale-Directed Therapy

Migraine is a common and often disabling condition, but its exact causes are not fully understood. Some people with migraines have a small opening in the heart wall called a patent foramen ovale (PFO). In some of these patients, closing this opening or taking a medication that inhibits blood platelets (prasugrel) has been shown to reduce migraines. However, not everyone benefits, and it is unclear why. This study is being done to better understand whether closing a PFO can provide lasting migraine relief - especially in patients whose migraines improve with prasugrel. The goal of this study is to find out whether, in patients whose migraines improve while taking prasugrel, closing the PFO along with 24 weeks of prasugrel leads to better long-term migraine relief after stopping the medication, than by taking prasugrel for 24 weeks alone. Participants will track their migraines daily using an electronic diary, then take prasugrel and compare their migraines while on the medication. Only patients whose migraines improve on this medication will continue in the study. Eligible participants will be randomly assigned (like flipping a coin) to one of two groups: 1) Medication-only group: Continue prasugrel for 24 weeks. 2) Procedure group: Undergo a minimally invasive procedure to close the PFO and continue prasugrel for 24 weeks. After treatment, the medication will be stopped in both groups, and participants will again track their migraines for about 8 weeks. The main question is: Do patients who have PFO closure continue to have fewer migraines after stopping prasugrel compared with those who did not have the procedure?

Determinants of SARS (Severe Acute Respiratory Syndrome)-COV2 (COVID-19) Persistence After Convalescence

The 2019-2020 COVID-19 pandemic is the largest outbreak in recent history. It is not known how long after someone gets sick with COVID-19 and recovers that they can still infect other people. It is also not known how quickly people make antibodies against the virus, which help clear infection from the body. The investigators will enroll 300 people who had COVID-19 based on lab testing or confirmed exposure to participate. An additional 25 participants who have never tested positive for COVID and have not had the vaccine will be enrolled as negative controls. Participants will complete a survey at enrollment. The investigators will also collect blood, nose swab, saliva, stool, semen, and breast milk to test for the virus. The investigators will ask participants to complete a survey and give specimens up to 12 times over 24 months. This information will be used to study how long the virus can live in different parts of the body, antibody development, and post-infectious complications. The investigators hope that this information will allow medical and public health providers to make recommendations to better care for patients in the convalescent phase of COVID-19 infection.

Diaphragmatic Hernia Research & Exploration, Advancing Molecular Science

The goal of this study is to identify genes that convey susceptibility to congenital diaphragmatic hernia in humans. The identification of such genes, and examination of their structure and function, will enable a delineation of molecular pathogenesis and, ultimately, prevention or treatment of congenital diaphragmatic hernia. There are many different possible modes of inheritance for congenital anomalies, including autosomal dominant, autosomal recessive, and multifactorial. Multi-factorial inheritance is responsible for many common medical disorders, including hypertension, myocardial infarction, diabetes and cancer. This type of inheritance pattern appears to involve environmental factors as well as a combination of genetic variations that together can predispose to or produce congenital anomalies, such as congenital diaphragmatic hernia. Our study is designed to establish a small, well-defined genetic resource consisting of 1) Nuclear families suitable for linkage analysis by parametric,non-parametric (e.g. sib pairs, TDT) and association techniques, 2) Individuals with congenital diaphragmatic hernia who can be directly screened for allelic variation in candidate genes, and 3) Individuals who can serve as controls (are unaffected by congenital diaphragmatic hernia). Neonates and their families will be collected from homogenous and heterogeneous populations. By characterizing diverse populations, it should be possible to increase the likelihood of demonstration of genetic variation in selected candidate genes that can then be used in association and linkage studies in individual subjects with congenital diaphragmatic hernia.

Preoperative Music Intervention for Anxiety in Hip and Knee Arthroplasty

Many patients feel anxious before joint replacement surgery. This anxiety is common - affecting roughly 1 in 3 patients - and research has shown that patients who are more anxious before surgery tend to have more pain afterward and may need more pain medication during recovery. Listening to music before medical procedures has been shown to reduce anxiety in many types of surgery. In fact, a recent analysis of 20 studies found that music works about as well as anti-anxiety medication for calming patients before surgery, with about 1 in 4 patients experiencing a meaningful benefit. However, almost all of this research has been done in other types of surgery. No study has specifically tested whether letting patients listen to their own preferred music before hip or knee replacement surgery reduces their anxiety. This study will randomly assign 52 patients scheduled for hip or knee replacement surgery to one of two groups: one group will listen to music of their choice through noise-cancelling headphones while waiting for surgery (for at least 20 minutes), and the other group will receive the usual preoperative care without music. Patients will fill out a brief 6-question anxiety survey when they arrive in the preoperative area and again just before being taken to the operating room. The study will also ask patients about their pain, anxiety, and overall experience after surgery, and will review their medical charts to see how much sedation and pain medication was used during the procedure. If music is shown to reduce anxiety in this setting, it could be easily adopted by any hospital at very low cost, offering patients a simple, drug-free way to feel calmer before their surgery.

A Multi-Level Strategy for De-implementing Mammography Overuse Among Older Women

This project aims to advance methodological and theoretical approaches for developing, selecting, refining, and piloting a multilevel de-implementation strategy to reduce the overuse of screening mammography in women aged ≥75 years. Informed by an innovative participatory, stakeholder-driven innovation tournament and a discrete choice experiment, the research team identified, prioritized, and tailored a multilevel de-implementation strategy. The research team will conduct a cluster randomized controlled trial (at the provider level) to test the impact of the provider- and patient-level components of the multilevel strategy on screening mammography use, and secondarily, on provider referrals/orders for screening mammography. The organizational level components of the multilevel strategy will be implemented among all participants, not via random assignment.

The AgRP and GH/IGF-1 Axis in Children

Recent data support the existence of a GH-Agouti-related peptide (AgRP) axis. The neuropeptide AgRP promotes food intake and has important effects on energy homeostasis. Recent evidence suggest that GH stimulates AgRP and AgRP may mediate some of GH's important nutritional and metabolic effects. main goals of this project are to characterize, for the first time, plasma levels of AgRP in children and to determine how these relate to GH and IGF-1 levels, age, body composition, clinical and other endocrine parameters. To accomplish this, we will conduct two studies, one being a cross-sectional study that will measure AgRP levels in 140 healthy children ages 5-17 and the second being a prospective study that will measure the change in plasma AgRP levels in response to GH treatment in 16 children who receive this as part of their clinical care for GH deficiency or short stature.

Brain Function and Cognitive Control Training in Children With Obsessive-Compulsive Symptoms

The goal of this clinical trial is to learn about brain function and cognition in children ages 8-12 who have subclinical obsessive-compulsive symptoms (OCS), such as unwanted thoughts or repetitive behaviors. The study will also examine whether patterns of brain activity are related to how children respond to cognitive training. The main questions this study aims to answer are: * Are there different patterns of brain activity related to cognitive control among children with OCS? * Are these patterns related to differences in OCS or cognition? * Can brain activity before training help predict changes in cognitive control or OCS severity after cognitive training? Participants will: * Complete clinical interviews, questionnaires, and tests of cognition. * Have a magnetic resonance imaging scan while completing a cognitive control task. * Complete video-game-based cognitive training on an iPad for about 25 minutes a day, 5 days a week, for 4 weeks. * Complete another set of clinical interviews and questionnaires after the training.

Genomic Uniformed-Screening Against Rare Disease In All Newborns

The goal of this study is to learn how genomic sequencing technology can be used to effectively expand the conditions screened on newborn screening. Newborn screening ensures equity and allows all babies to have the same chance at the healthiest life. Families will be invited to have their newborn baby screened for additional conditions beyond what all babies are screened for as part of the newborn screening public health program. Families can choose to be part of the study or choose not to be part of the study and just have the routine newborn screening test. Families will also be able to choose to learn about their baby's risk for conditions that have effective treatments available but are not on the routine newborn screening panel or also learn about conditions for which there is not currently FDA approved medications but for which medications are under development or for which early intervention services or treatment of seizures may improve the child's outcome. Families will be invited to the study shortly after the baby is born and will learn the decision not to participate, and we will interview a subset of parents who agree to be interviewed. Newborns who screen positive will be referred to appropriate providers for care and will be followed through review of electronic medical records and parental follow up via phone, text, postal mail or email.

Spinal Cord Associative Plasticity in Cerebral Palsy

Associative plasticity has been used to promote functional recovery from conditions affecting movement. The long term goal of this project is to use electrical stimulation techniques to improve arm and hand function. The goal of this prospective experimental study in adults with hemiplegic cerebral palsy (hCP) is to test the effects of pairing hand motor cortical and median nerve stimulation targeted to induce plasticity in the cervical spinal cord. Based on preliminary data in neurotypical adults, the investigators are testing the effects of this approach in adults with hCP. This study will first verify the present stimulation parameters as sufficient to promote induction of associative plasticity of sensorimotor connections for manual dexterity in adults with hCP. This will be assessed through neurophysiological, biomechanical, and clinical functional outcome measures. Successful pairing showing meaningful improvements in dexterity could then be used as an impetus for a larger study examining the efficacy of SCAP in people with hCP.

Decellularized Human Placental Extracellular Matrix Tissue for Rotator Cuff Repair Augmentation

The rotator cuff is a set of muscles and tendons that help move the shoulder. Tears in the rotator cuff are common, particularly as people age. Consequently, rotator cuff repair surgeries are common, as well. Despite the frequency with which rotator cuff repairs are performed, there remains a high rate of postoperative failure to heal. In such situations, there is a lack of connective tissue establishment between the rotator cuff tendon and the bone. One strategy to attempt to improve healing of the rotator cuff tendon back to the bone is via the use of extracellular matrix allograft. This treatment is composed of tissue from other humans, which is stripped of its cells so that just the scaffolding around the cells remains. This decellularized scaffolding can be placed at the rotator cuff healing site in an attempt to augment healing. Both animal studies and human studies have shown promise with this approach. Of those patients enrolling in the study, 50% will be assigned at random to receive a standard rotator cuff repair AND allograft treatment, while 50% will be assigned at random to receive standard rotator cuff repair WITHOUT allograft treatment. All patients enrolled in the study will also obtain an MRI at one year following surgery in order to assess tendon healing. Of note, one-year postoperative MRIs are not standard following rotator cuff repair - only those enrolled in the study will receive this MRI. There will be no financial consequence of receiving this MRI.

Alpelisib Challenge Test (ACT)

The goal of this study is to test a potentially easier method for measuring how much insulin a person is capable of producing than the current gold-standard method, the "hyperglycemic clamp." Participants will come in for a two-day (overnight) visit in which they will first undergo a "hyperglycemic clamp," in which they receive an intravenous (into the vein) infusion of glucose (sugar) in order to measure the maximum amount of insulin their body produces in response. They will then consume a series of three standardized meals throughout the rest of the day. At 23:00, they will take a single dose of alpelisib, a drug that interferes within insulin's actions in the body. Then, the following morning, they will undergo a "Mixed Meal Tolerance Test" in which they consume a standardized liquid nutritional beverage and have blood drawn periodically before and during the test.

Graded Insulin Suppression Test P&F

The goal of this study is to learn about how the hormone insulin controls blood sugar in a variety of people. The main question it aims to answer is about how much insulin the body actually needs to maintain a normal blood sugar level. Participants will be asked to come in for a one-day study visit in which they will undergo a "graded insulin suppression test" ("GIST"). The GIST involves intravenous (into the vein) infusions of octreotide, a medication that turns off the body's own production of insulin, as well as replacement of insulin at two different levels (low and high), with or without replacement of glucagon, and glucose (sugar). The study investigators will check blood sugar levels every few minutes during the procedure to determine the effect of the two different insulin levels. This study will evaluate the GIST in both healthy volunteers and those at higher risk for type 2 diabetes.
