Osteoporosis is an age related disease in which a person's bone slowly becomes weaker with time. The bones may become so weak that they break easily such as a fall from standing height. The most commonly broke bones in osteoporosis are those of the hip, the spine or the wrist. Osteoporosis runs in families meaning that genetic differences explain why some people break bones in old age and other do not. Genetic studies have been done that show the the genes associated with spine (vertebral) fractures (broken bones) and hip fractures are different, suggesting that osteoporosis of the spine is not the exact same disease as osteoporosis of the hip. Genetic studies tell us what part of the genome (i.e. genes) are associated with a disease, but do not tell us how these genes act biologically to cause that disease. In this study, we seek to determine how the genes uniquely associated with spine osteoporosis behave in normal and aged bone, to determine how they interact with each other as a team to impact spine bone. In this study, we will measure gene activity (so called gene expression) in bone samples taken from people undergoing major spine deformity surgery. We will using genetic data from these patients to determine how gene activity is controlled in bone and how that relates to measures of bone health such as bone mineral density data. The results of this study will provide critical data regarding how osteoporosis of the spine happens, and these data will be used to find better and safer treatments to prevent bone fractures of the spine that happen with age.

This standardized prospective long-term outcome analysis will help reaffirm these findings via a multicenter patient cohort and describe the best practices/techniques for stabilization of the autograft and right ventricular outflow tract reconstruction. Read Less

This study will examine a potential relationship between family history of obesity, that is whether people with at least one parent who had obesity in adulthood compared to people with two parents who did not have obesity in adulthood, and the ability of protein intake to curb further intake of food.

The risk of developing a blood clot occurs in up to 60% of all critical care patients. Many times enoxaparin (or Lovenox) is given to patients who are at a higher risk of developing clots in their legs or lungs. There are two standard doses of enoxaparin that are recommended by the drug companies. These two doses have never been directly compared in trauma, general, and vascular surgery patients. The purposes of this study are: 1. to compare the development of blood clots in patients receiving 30mg twice daily of enoxaparin compared to patients receiving 40mg once daily of enoxaparin. 2. to determine if there is higher risk of bleeding complications in patients receiving 30mg twice daily of enoxaparin compared to patients receiving 40mg once daily. Patients enrolled into the study will be randomized to receive enoxaparin, 30mg twice daily or enoxaparin, 40mg once daily. Patients will then be monitored for signs and symptoms of blood clots. At the time of discharge (or before, if medically indicated), an ultrasound test will be performed to look for blood clots in the patient's legs. The investigators will compare incidence of blood clots formed between the 2 groups of patients to determine if one dose of enoxaparin relates to a lower rate of blood clots in critically ill patients. The investigators will also compare the incidence of bleeding complications between the 2 groups. Read Less

The Human Trisome Project will significantly increase the speed of Down syndrome research and the understanding of associated medical conditions. Its biobank will provide de-identified samples to research. Read Less

FOXP1, also known as Forkhead-box Protein P1, is a transcription factor protein belonging to the FOX gene family. Disruptions in the FOXP1 gene cause a phenotype characterized by global developmental delay, speech deficits, mild dysmorphic features, and traits of autism spectrum disorder. This study seeks to characterize FOXP1-related neurodevelopmental disorders using a number of genetic, medical and neuropsychological measures. Read Less

The overarching goal of the proposed project is to evaluate a randomized clinical trial of the Pregnant Moms' Empowerment Program aimed at detecting its effects on maternal mental health, re-victimization, parenting sensitivity, and infant development. The project also seeks to examine theoretically-grounded mechanisms of change, including social support and empowerment. Women participating in the study will receive either the PMEP or participate in a contact-equivalent active control group during pregnancy, and will be interviewed at baseline, post-intervention and with their infants at 3 months and 1 year old. The study will occur at two sites - the University of Notre Dame and the University of Memphis. Participants will be recruited from the local community at both locations, with an equal number of women drawn from each site - Memphis, Tennessee (n=115) and South Bend, Indiana (n=115). Enrollment will continue for approximately 2.5 years, with an expected rate of 8 eligible women per month, based on a pilot study of the Pregnant Moms' Empowerment Program. The expected duration of the study for each participant will be approximately 1.5 years, with some variation due to women enrolling at different points in their pregnancy. The primary objective of the proposed project is to determine if the Pregnant Moms' Empowerment Program has positive effects on maternal mental health, re-victimization rates, parenting sensitivity, and infant development compared to women's participation in a contact-equivalent active control group. This objective will be evaluated using a multi-site randomized clinical trial design. Participants (N = 230) will be equally randomized into study arms. Eligible women will include those who are: 1) currently pregnant (primi or multiparous) and between 10 and 30 weeks gestation, 2) experienced IPV within the past year, 3) English speaking and 4) age 16 or older. The study will include 9 total visits: 4 assessments and 5 sessions for both study arms. In-person assessment visits will be completed by a trained research assistant; each visit will take approximately 2-3 hours, with post-partum assessments somewhat longer than prenatal assessments given the addition of the infant developmental assessment and parent-child observation task. Women will be compensated $30 for the first two assessments and $50 for the second two assessments. Following the final assessment, women will be invited to complete a daily diary (virtually) each day for 30 days. Each survey will take approximately 5-10 minutes to complete, and women will be compensated $2 for each completed survey. Women will also receive a $10 bonus for each set of 10 consecutive surveys. Treatment sessions will be 2 hours in duration. Women in the PMEP will complete a structured set of sessions: (1) supporting each other, support in the community, (2) identifying and understanding sources of distress, (3) cognitive and behavioral strategies to build resilience and resolve conflict, (4) perinatal health and infant care, and (5) positive parenting. Women in the active control condition will participate in facilitated discussions on a topic identified by the group. All sessions will be audio recorded so that treatment fidelity can be evaluated (for the Pregnant Moms' Empowerment Program) and so that content overlap can be assessed (for the active control condition).

The goals of this study are to uncover the influence of diet on the human circadian timing system. The protocol is a 46-day (28 outpatient days, 18 inpatient days over two 9 day visits) randomized cross-over study designed to elucidate the speed of entrainment in response to a high-fat diet.

The purpose of this research study is to evaluate the usefulness of a wearable robotic exoskeleton device (Ekso-GT), to improve learning and memory, and gait therapy in persons with walking disability due to Multiple Sclerosis. The study will evaluate the mobility, learning and memory, and walking abilities of individuals with multiple sclerosis who went through the traditional as compared to others who used the robotic exoskeleton as part of their therapy.
