Cirrhosis is characterized by loss of muscle as well as fat mass, which increases morbidity and mortality before, during, and after liver transplantation. A common mechanism for the reduced muscle and fat mass in cirrhosis is an increased expression of the TGF (transforming growth factor)beta superfamily member, myostatin, in the muscle and adipose tissue. The present study will examine the expression of myostatin, its receptor and intracellular signaling pathways in the skeletal muscle and mesenteric adipose tissue in cirrhotic patients undergoing liver transplantation as compared to healthy controls undergoing planned abdominal surgery. 16 cirrhotic patients will be identified from the transplant list, and 16 healthy controls from outpatient surgery lists. Nutritional assessment will be performed, including anthropometry (triceps skinfold thickness, mid arm circumference), dual energy x-ray absorptiometry (DEXA), and bioelectrical impedance analysis (BIA). Rectus abdominis muscle tissue and omental fat tissue will be harvested in the operating room, and the expression of signaling proteins involved in skeletal muscle protein synthesis will be quantified. The investigator will also quantify the expression of genes involved in lipolysis and lipid synthesis. The investigator anticipates that the expression of myostatin will be higher in the skeletal muscle and adipose tissue of cirrhotics as compared to controls. There will be a reduction in the expression of the signaling proteins that regulate skeletal muscle protein synthesis, as well as the expression of genes regulating lipogenesis. The increased expression of myostatin will also correlate with reduced anthropometric and DEXA measurements of lean body mass and fat mass. Read Less

Photobiomodulation therapy (PBMT) involves applying non-ionizing forms of light from sources including lasers, LEDs, and broadband light, in the visible and near infrared spectrum, to the body to enhance performance, stimulate healing, modulate recovery, and improve health. The investigators will conduct a single-blinded randomized-control trial with sham control to investigate the effectiveness of providing PBMT in a military population, translating this cutting-edge research to application in the operational setting.

A heart attack occurs when blood flow is disrupted to the heart and is related to both the blockage and flow restoration (reperfusion injury). An occlusion during a heart attack can be cleared (mostly via stents), but there are no methods to decrease reperfusion injury even though animal studies have found that "preconditioning" has powerful protective effects. Through the observation of Jewish men wearing tefillin the investigators have discovered a method of bringing preconditioning to patients at risk for heart attacks. This study will focus on women as the majority of people who wear tefillin (and have been studied) are men. Read Less

Aphasia, or language impairment after a stroke, affects approximately 2 million people in the United States, with an estimated 180,000 new cases each year. The medical community cannot predict how well someone with aphasia will respond to treatment, as some people with aphasia are poor responders to intervention even when participating in empirically supported treatments. There is a strong likelihood that genetics play a role in language recovery after stroke, but very little research has been dedicated to investigating this link. This study will investigate whether two genes and cognitive abilities, such as memory, predict responsiveness to aphasia therapy for word-retrieval difficulties. Read Less

This Phase II open-label, uncontrolled, multicenter trial is designed to investigate the pharmacokinetic (PK) profile of gadopiclenol in plasma, in pediatric patients aged up to 23 months inclusive (term neonates or preterm infants after the neonatal period), using a population PK approach. Primary objective is to evaluate the PK profile of gadopiclenol in plasma following single intravenous injection of 0.05 mmol/kg body weight (BW) in pediatric population aged up to 23 months (inclusive) scheduled for a contrast-enhanced MRI examination of any body region including central nervous system (CNS).

Individuals with Down syndrome (DS) live with visual deficits due, in part, to elevated levels of higher-order optical aberrations (HOA). HOAs are distortions/abnormalities in the structure of the refractive components of the eye (i.e. the cornea and the lens) that, if present, can result in poor quality focus on the retina, thus negatively impacting vision. HOAs in the general population are overall low, and thus not ordinarily considered during the eye examination and determination of refractive correction. However, for some populations, such as individuals with DS, HOAs are elevated, and thus the commonly used clinical techniques to determine refractive corrections may fall short. The most common clinical technique for refractive correction determination is subjective refraction whereby a clinician asks the patient to compare different lens options and select the lens that provides the best visual outcome. Given the cognitive demands of the standard subjective refraction technique, clinicians rely on objective clinical techniques to prescribe optical corrections for individuals with DS. This is problematic, because it may result in errors for eyes with elevated HOA given that these techniques do not include measurement of the HOAs. The proposed research evaluates the use of objective wavefront measurements that quantify the HOAs of the eye as a basis for refractive correction determination for patients with DS. The specific aim is to determine whether dilation of the eyes is needed prior to objective wavefront measurements. Dilation of the eyes increases the ability to measure the optical quality of the eye and paralyzes accommodation (the natural focusing mechanism of the eye), which could be beneficial in determining refractions. However, the use of dilation lengthens the process for determining prescriptions and may be less desirable for patients. Read Less

Fractional oxygen during mechanical ventilation, is a life sustaining therapy in the intensive care unit , used for about a million patients annually. Oxygen therapy needs to be tightly balanced as both hypoxia and hyperoxia are harmful. Establishing precision in oxygenation has significant implications for improving patient outcomes, resource utilization and reducing iatrogenic harm to a vulnerable population. The investigators propose an approach using a oxygen titration protocol consisting of electronic health records based alerts to guide oxygen adjustment. Read Less

Children requiring inpatient rehabilitation treatment following acquired brain injury (ABI) are at risk for poor engagement in rehabilitative therapies. A within subject crossover design will be used to determine whether involving dogs in physical and occupational therapies while receiving inpatient rehabilitation improves patient engagement, how involving dogs improves engagement, and identify who is most likely to benefit. This project addresses the critical need to establish an evidence base for animal-assisted therapies in pediatric rehabilitation, incorporates innovative methods, and has the potential to lead to improved clinical care for children and adolescents receiving intensive rehabilitation following ABI.

This is a single-site, single-arm, single-dose, Phase 1 study of the safety of bryostatin in participants with multiple sclerosis (MS) receiving any disease modifying therapy (DMT). Read Less

Children with developmental language disorders (DLD, aka specific language impairment), a prevalent pediatric disorder, experience hallmark grammar deficits with life-long impacts on educational and occupational outcomes. While effective and early interventions can mitigate the impact of DLD, not enough is known about the neural basis of DLD in young children, yet is needed to inform the design of more individualized interventions. This project uses neuroimaging, along with behavioral methods, with the goal of better understanding the memory-language mechanisms that underlie grammar learning and impairment, while also considering their association to treatment-related changes in preschoolers with DLD.
