This project will be a multi-center, prospective longitudinal cohort for all patients undergoing primary shoulder instability surgery, excluding isolated SLAP repairs. We will be looking for risk factors for recurrent instability, revision surgery, and poor outcomes. Patients will be asked to complete the RAND-36, ASES, Shoulder Activity, EQ-5D and WOSI outcome measures, as well as demographic and socioeconomic information. Surgeons will complete a form after surgery with information on radiographic findings, physical exam, surgical findings, and the repair. Patients will wear a sling post-operatively, and follow standardized rehabilitation protocols, including physical therapy. Patients will be sent outcome questionnaires at 2, 6, 10, and 20 years after surgery. Read Less

The purpose of this study is to determine the maximum dose that is safely tolerated of the experimental drug Rhenium Re 188 P2045. This will be done by first treating patients at relatively low doses of Rhenium Re 188 P2045, observing them closely to assure that there are no bad side effects, then increasing the dose when we are confident that it is safe to do so.

The goal of this study is to determine the effects of stimulant medication on disruptive behavior, function, preference and choice; however, it is primarily methodological and will add to current research by establishing an effective evaluation of the impact of stimulant medication on these behaviors. Three behavior assessments for children and adolescents diagnosed with AD/HD who exhibit disruptive behavior will be conducted: Preference assessments will be conducted to determine whether preference for social and nonsocial items and activities differs under medication and non-medication conditions. Functional analyses will be conducted to determine whether stimulant medication has an effect on the frequency and function or purpose of disruptive behavior. Choice assessments will be conducted to evaluate the impact of stimulant medication on impulse control/delay discounting. This study will be conducted in three phases. For each of the 5 to 10 participants there will be 8 total visits. The first 4 visits will entail a preference assessment, followed by a functional analysis. On visits 1 and 3, the participant will be asked to take his/her stimulant medication as is typically done; however, on visits 2 and 4, the participant will be asked to refrain from taking the medication. For visits 5-8, participants will continue to participate in preference assessments, but will also be presented with a choice arrangement with work and play. In the choice arrangement, participants will be given four work cards and four play cards that they can organize in any order. Work cards will be associated with a brief academic task and play cards will be associated with a brief play period using high-preferred toys/activities. On visits 5 and 7 the participant will be asked to take his or her stimulant medication as usual, while on visits 6 and 8 the participant will be asked to refrain from taking his or her medication.

Following treatment for a primary extremity sarcoma, patients remain at risk for the development of local and systemic disease recurrence. Metastasis (distant recurrence) to the lung is the most frequent single location of disease recurrence in sarcoma patients, occurring in almost half of all patients. Therefore, careful post-operative surveillance is an integral element of patient care. However, the detection of metastases does not necessarily affect long-term survival and may negatively impact quality of life. Surveillance strategies have not been well researched and have been identified as the top research priority in the extremity sarcoma field. Using a 2X2 factorial design to maximize efficiency and reduce overall trial costs, the SAFETY trial will randomize 830 extremity soft-tissue sarcoma (STS) patients to determine the effect of surveillance strategy on overall patient survival after surgery for a STS of the extremity by comparing the effectiveness of both surveillance frequency (every 3 vs. every 6 months) and imaging modality (CT scans vs. chest radiographs).

The U.S. Committee for Refugees and Immigrants (USCRI) has developed the Relationships, Education, Advancement, and Development for Youth for Life (READY4Life) Program. This is a 16-hour program for immigrants/refugees, ages 14 to 24. The program is designed to help young immigrants and refugees prepare for a successful life in the United States. The program is taught by USCRI program staff and is being implemented at eight sites across the U.S.: Cleveland, Ohio; Colchester, Vermont; Des Moines, Iowa; Miami, Florida; Philadelphia, Pennsylvania; Raleigh, North Carolina; Saint Paul, Minnesota; and Twin Falls, Idaho. The project also includes a rigorous evaluation component, featuring a Randomized Control Trial (RCT) design. Read Less

Background: Over the past few decades, fructose is increasingly being used as a sweetener/ additive in a variety of foods. Incomplete absorption of fructose has been implicated as a cause of gastrointestinal symptoms. In tertiary care centers, the prevalence of fructose malabsorption in subjects with unexplained GI symptoms is thought to be between 11-50%, when assessed with breath tests following administration of 25 grams of fructose in a 10% solution. Restriction of dietary fructose has been shown to improve symptoms in these patients to an extent. Currently, there are no therapeutic agents that improve intestinal fructose absorption and thereby decrease symptoms. Studies in the pediatric population have shown that fructose absorption in the small intestine is increased in the presence of glucose or amino acids, especially alanine. Objective: The investigators' objective is to assess whether co-administration of an oral solution of L-alanine facilitates fructose absorption and decreases gastrointestinal (GI) symptoms associated with fructose malabsorption in subjects undergoing standard fructose breath test when compared to placebo. Methods and analysis: The investigators propose a randomized, double-blind study in 40 subjects with known fructose intolerance. After an overnight fast, each subject will receive an oral solution of 12.5 grams of alanine in 125cc of water or placebo. Next, the subject will receive an oral solution of 25 grams of fructose in a 10% solution. Serum, urine and breath samples will be collected at baseline and at 30-minute intervals for 4 hours. GI symptoms will also be assessed and recorded at 30 minute intervals using a standard questionnaire. Repeated measures ANOVA will be used to compare the data obtained during the study protocol with the baseline (pre-study) data. Expected outcomes: Co-administration of alanine with fructose may improve fructose absorption and decrease symptoms in subjects with fructose intolerance. Hypothesis: Ingestion of alanine along with fructose, will facilitate intestinal absorption of fructose in subjects with fructose malabsorption. Aim: To investigate the effects of co-administration of equi-molar doses of alanine on a) the absorption of fructose and b) the occurrence of GI symptoms in subjects with fructose malabsorption.

Women who develop preeclampsia during pregnancy are more likely to develop cardiovascular disease later in life, even if they are otherwise healthy. The reason why this occurs is unclear but may be related to blood vessel damage and increased inflammation that occurs during the preeclamptic pregnancy and persists postpartum. The purpose of this investigation is to 1) determine the mechanisms contributing to this lasting blood vessel damage and chronic inflammation, and to 2) identify factors (both physiological and pharmacological) that mitigate these negative effects in order to inform better clinical management of cardiovascular disease risk in women who have had preeclampsia.

Subjects will participate in a 2-visit study protocol in which they will be administered cannabis of pre-determined concentrations and asked to complete a simulated drive in a driving simulator. Subjects will be scanned on two SpotLight-THC (Alpha and Beta iterations) devices and peripheral venous whole blood will be collected from subjects for analysis on up to four occasions on each visit. The purpose of the investigation will be to determine whether the SpotLight-THC device is a reliable measure of THC impairment at the roadside, with an objective to identify a unique blood analyte architecture for THC impairment using near infrared light and machine learning.
