Cardiovascular health in adults conceived with assisted reproductive technology
The purpose of this study is to better understand heart and blood vessel health in adults conceived through assisted reproductive technology (such as IVF) compared to adults conceived naturally. Participants will complete one study visit lasting approximately 3–4 hours. During the visit, participants will complete questionnaires, have basic health measurements taken, and complete non-invasive tests that assess blood pressure, blood vessel function, and circulation. Researchers hope the findings will improve understanding of long-term cardiovascular health in adults conceived through assisted reproductive technology.

Assessment of usability and satisfaction with a take-home device presenting sound and body stimulation for back pain
The purpose of this study is to measure the compliance, usability, and satisfaction of an at-home, multi-modal stimulation device in a diverse population of people with chronic lower back pain (cLBP) compared to a group of participants who are engaging in integrative health practices. The multi-modal device will include a combination of electrical stimulation, auditory stimulation, and integrative-health techniques, including mindfulness breathing, health coaching, and reflective journaling. The multi-modal device creation is based on prior knowledge in lower back pain treatment, which includes electrical stimulation of the back (Transcutaneous Electrical Nerve Stimulator or TENS) and integrative health modalities.

A Randomized Double Blind Phase II Trial of Restorative Microbiota Therapy (RMT) or Placebo in Combination with Durvalumab (MEDI4736) and Tremelimumab With Chemotherapy in Treatment Naïve Advanced or Metastatic Adenocarcinoma Non-Small Cell Lung Cancer
The investigational therapy in this study is referred to as Restorative Microbiota Therapy (RMT). It is prepared by extracting healthy bacteria from the stool of healthy human donors and making it into capsules taken by mouth. The donor stool samples are rigorously tested for harmful bacteria and viruses before processing. There is scientific evidence to suggest that RMT might make immunotherapy more effective.

STOP PEDS RCT (Streamlined Treatment of Pulmonary Exacerbations in Pediatrics Randomized Controlled Trial) (STOP PEDS RCT)
In this study, we are going to compare two ways of treating mild respiratory illnesses in children with Cystic Fibrosis (CF). One is immediate antibiotics (increase airway clearance and start oral antibiotics right away) and the other is tailored therapy (increase airway clearance right away but only start oral antibiotics if symptoms worsen or do not improve). We are looking at how safe each option is and how well each one works. To do this, we will randomize participants (like flipping a coin) to one of these two approaches if a mild respiratory illness happens over the next 12 months.

NEPTUNE: The Nephrotic Syndrome Study Network - RDCRN Protocol 6801 (NEPTUNE)
Nephrotic syndrome is a condition which affects the kidneys causing them to leak protein from the blood into the urine. Nephrotic syndrome is a disease that can improve (remission) and worsen (relapse) at different times throughout childhood. By collecting health information and laboratory samples, our goal is to learn more about these kidney diseases and find better ways to prevent and treat people with nephrotic syndrome. New knowledge will be shared with researchers and the public.

Development and Validation of an MRI-Compatible Jaw Metabolic Stressor Task_Study1
The goal of this study is to develop and test a new way of measuring how much effort and strain the jaw muscles can handle before a person begins to feel specific levels of pain or fatigue. This involves a controlled jaw exercise task designed to better understand the relationship between jaw muscle effort, physical stress in the muscles, and how each person experiences discomfort. It is hoped that the information learned in this study will help researchers refine this new jaw testing method and confirm whether it accurately measures jaw muscle effort and discomfort. This may support future research that improves how jaw pain conditions are understood and eventually lead to better, more individualized treatments for people with jaw muscle and jaw joint disorders.

A Randomized Phase III, Two-Arm Trial of Paclitaxel/Carboplatin/Maintenance Letrozole Versus Letrozole Monotherapy in Patients with Stage II-IV, Primary Low-Grade Serous Carcinoma of the Ovary or Peritoneum
We are looking at how well letrozole with or without paclitaxel and carboplatin works in treating patients with stage II-IV low-grade serous carcinoma of the ovary, fallopian tube, or peritoneum. Letrozole is an enzyme inhibitor that lowers the amount of estrogen made by the body and may stop the growth of tumor cells that need estrogen to grow. We will compare the effectiveness of the two different treatments.

AHOD2131, A Randomized Phase 3 Interim Response Adapted Trial Comparing Standard Therapy with Immuno-oncology Therapy for Children and Adults with Newly Diagnosed Stage I and II Classic Hodgkin Lymphoma
This phase III trial studies brentuximab vedotin and combination chemotherapy to see how well they work compared to combination chemotherapy alone in treating children and young adults with stage IIB with bulk, stage IIIB, IVA, or IVB Hodgkin lymphoma. Combinations of biological substances in brentuximab vedotin may be able to carry cancer-killing substances directly to Hodgkin lymphoma cells. Chemotherapy drugs, such as doxorubicin hydrochloride, bleomycin sulfate, vincristine sulfate, etoposide, prednisone, and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known if combination chemotherapy is more effective with or without brentuximab vedotin in treating children with high-risk Hodgkin lymphoma.

The effects of vagus nerve stimulation on intrinsic lower leg spinal motoneuron excitability in Parkinson's disease
This study is designed to better understand the mechanisms contributing to impaired activation of leg muscles in people with Parkinson’s disease (PD) and test if stimulation of a nerve at the neck (vagus nerve) can improve muscle activation, walking and balance. People can participate in one of two experiments, or both. Both experiments will test the muscle activation patterns in the lower leg when producing low levels of force. We will also assess walking and balance. Experiment 2 will test muscle activation patterns, walking and balance before and after vagus nerve stimulation. We are also asking people who don’t have PD and are 21 to 76 years old and match in age and sex to participants to undergo the same study procedures.
