The purpose of this study is to investigate the safety and effectiveness of bone marrow aspirate concentrate (BMAC) in patients with moderate to severe osteoarthritis of the knee. BMAC provides a rich source of mesenchymal stem cells (MSCs) and is a stem cell-based therapy that has been reported to preserve or improve the structure of joints. The Angel System is the device used in this study to concentrate bone marrow from the patient and is intended to separate a mixture of blood and bone marrow and collect plasma rich platelets preoperative to a surgical procedure. The goal of this study is to identify whether BMAC can be an effective and safe treatment for patients with osteoarthritis of the knee. Read Less

ADHOC-LA is an observational study of people living with HIV who either are taking, or have taken, a long-acting injectable therapy to manage their HIV. Data from this study will be used to research the ways in which HIV impacts the lives of these patients. Read Less

The purpose of this study is to determine whether a program to optimize patient physical fitness and nutrition ("prehabilitation") prior to and after plastic surgery involving the abdomen improves surgical outcomes. The investigators hope to determine how a multimodal peri-operative prehabilitation program can be most effective in engaging and motivating patients to physically and mentally get ready for an abdominally-based plastic surgery operation. The overall goal is to determine if this program will improve post-operative recovery after abdominally-based plastic surgery. The importance of this new knowledge is better understanding of ways that plastic surgeons can improve outcomes, engagement, and experience of patients undergoing abdominally-based plastic surgery operations. This would translate to increased healthcare value and better long-term outcomes. Read Less

The primary objective of the study is to characterize the concentrations of casirivimab+imdevimab in serum over time after a single subcutaneous (SC) administration The secondary objectives of the study are: To assess the safety and tolerability of SC or single administration of casirivimab+imdevimab To assess the occurrence of grade ≥3 injection site reactions and grade ≥3 hypersensitivity reactions, in participants treated with SC doses of casirivimab+imdevimab To assess the immunogenicity of casirivimab+imdevimab Read Less

Approximately one fourth of cases of endometrial cancer (EC) are diagnosed in premenopausal women, of whom approximately 40% wish to preserve their fertility. When arising in young women, EC usually presents with favorable prognostic features, as a focal, well differentiated endometrioid tumor, with minimal or absent myometrial invasion. This profile corresponds to the Type 1 EC, which correlates with the estrogen/progesterone receptor positive (ER+/PR+) pattern. On the other hand, these patients frequently present with clinical signs of a hyperestrogenism (chronic anovulation, infertility, obesity). Primary progestin therapy has been demonstrated to be effective in early well differentiated tumors and in poor operative candidates with response rates ranging from 58-100%.Currently, the therapeutic approach to an early stage EC consists of a staging laparotomy/laparoscopy, including a total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH-BSO), peritoneal washings, and lymphadenectomy (pelvic and aortic), depending on the pathological risk profile pre- and intraoperatively determined. Therefore, the current standard of surgical approach is preclusive of fertility. The worldwide experience and data on conservative management of EC are, however, still limited. Most of reports based on cases retrospectively collected, harboring potential methodological bias, using different treatments and drugs, and with insufficient follow-up. Some systematic reviews have been published in the last decade, trying to summarize the literature data. Therapeutic results seem to be promising with a regression rate of approximately 75% and relapse occurring in 25-40% of cases, with anecdotical reports of deaths of disease (DOD). The fertility outcome was, however, not satisfying with about 30% pregnancy rate in patients attempting to conceive, and an overall low rate of assisted reproductive techniques (ART) despite the subfertile clinical profile.Therefore, there is a need for a prospective, multicentre cooperative project able to systematically collect data from consecutive patients treated according to defined (not necessarily identical) protocols, concerning the oncological, as well as, the obstetrical outcomes. Moreover, this project could represent the "template" in which a pretreatment fertility counseling, psychological support, and definitive surgery are routinely included according to shared criteria.

This is an adaptive, Phase II/III study in 2 parts (i.e. Part 1 (dose ranging) and Part 2 (Hypothesis testing)). NaBen® is granted Breakthrough Therapy Designation by US FDA as treatment for refractory schizophrenia. Part 1 Objectives: There are two primary objectives for Part 1 of this study: 1. To evaluate, in terms of dose-response, the effectiveness of NaBen® (1000 and 2000 mg/day) compared to Placebo (0 mg/day), when combined with clozapine, in improving the residual symptoms associated with refractory schizophrenia in adults, and; to determine the optimal dose to be used in Part 2 of this study. 2. Sample size re-assessment to evaluate the final sample size needed to proceed with Part 2 of the study The secondary objective of the Part 1 of this study is to evaluate the safety and tolerability of NaBen® (1000 and 2000 mg/day) compared to Placebo (0 mg/day), in combination with clozapine. Part 2 Objectives: The primary objective of the Part 2 of this study is to evaluate the effectiveness of NaBen® (at the optimal dose determined in the Part 1 of this study) compared to Placebo (0 mg/day), when combined with clozapine, in improving the residual symptoms associated with refractory schizophrenia in adults. The secondary objective of the Part 2 of this study is to evaluate the safety and tolerability of NaBen® (at the optimal dose determined in the Part 1 of this study) compared to Placebo (0 mg/day), in combination with clozapine.

The Congenital Muscle Disease Patient and Proxy Reported Outcome Study (CMDPROS) is a longitudinal 10 year study to identify and trend care parameters, adverse events in the congenital muscle diseases using the Congenital Muscle Disease International Registry (CMDIR) to acquire necessary data for adverse event calculations (intake survey and medical records curation). To support this study and become a participant, we ask that you register in the CMDIR. You can do this by visiting www.cmdir.org. There is no travel required. The registry includes affected individuals with congenital muscular dystrophy, congenital myopathy, and congenital myasthenic syndrome and registers through the late onset spectrum for these disease groups. The CMDIR was created to identify the global congenital muscle disease population for the purpose of raising awareness, standards of care, clinical trials and in the future a treatment or cure. Simply put, we will not be successful in finding a treatment or cure unless we know who the affected individuals are, what the diagnosis is and how the disease is affecting the individual. Registering in the CMDIR means that you will enter demographic information and complete an intake survey. We would then ask that you provide records regarding the diagnosis and treatment of CMD, including genetic testing, muscle biopsy, pulmonary function testing, sleep studies, clinic visit notes, and hospital discharge summaries. Study hypothesis: 1. To use patient and proxy reported survey answers and medical reports to build a longitudinal care and outcomes database across the congenital muscle diseases. 2. To generate congenital muscle disease subtype specific adverse event rates and correlate with key care parameters. Read Less

The standard of care imaging of prostate cancer metastases recommended by the National Comprehensive Cancer Network (NCCN), CT of the chest/abdomen/pelvis and bone scan, may be suboptimal. PyL is a novel PET tracer designed to detect prostate specific membrane antigen (PSMA) expressed on prostate cancer cells. PyL PET/CT may provide improved evaluation of clinically significant metastases in patients with prostate cancer. Read Less
