This project is a 2-phase, randomized clinical trial that includes 7 days of unilateral leg disuse (Phase 1), immediately followed by 1 week of bilateral leg rehabilitation (Phase 2). The investigators will recruit cohorts of healthy middle-aged men and women to address their aims: - Demonstrate the sex-specific effects of skeletal muscle disuse (Phase 1) - Identify key molecular determinates of susceptibility of skeletal muscle atrophy (Phase 1) - Map the early, sex-specific molecular time-course of rehabilitation (Phase 2) - Determine if disused and healthy muscle respond similarly to exercise (Phase 2) Healthy, middle-age men and post-menopausal women (50-65 years) will be recruited from the greater Houston/Galveston area. This under-represented research demographic demonstrate few negative metabolic or phenotypic signs of advanced age, but are at increased risk of being hospitalized and experiencing accelerated loss of lean mass and muscle function that parallels a much older population. The goal of this study is to characterize phenotypic and molecular skeletal muscle changes in middle-aged men and women during critical periods of disuse and rehabilitation and ultimately direct the development of targeted and effective prevention and treatment strategies.

This phase III trial compares the effect of adding levocarnitine to standard chemotherapy versus (vs.) standard chemotherapy alone in protecting the liver in patients with leukemia or lymphoma. Asparaginase is part of the standard of care chemotherapy for the treatment of acute lymphoblastic leukemia (ALL), lymphoblastic lymphoma (LL), and mixed phenotype acute leukemia (MPAL). However, in adolescent and young adults (AYA) ages 15-39 years, liver toxicity from asparaginase is common and often prevents delivery of planned chemotherapy, thereby potentially compromising outcomes. Some groups of people may also be at higher risk for liver damage due to the presence of fat in the liver even before starting chemotherapy. Patients who are of Japanese descent, Native Hawaiian, Hispanic or Latinx may be at greater risk for liver damage from chemotherapy for this reason. Carnitine is a naturally occurring nutrient that is part of a typical diet and is also made by the body. Carnitine is necessary for metabolism and its deficiency or absence is associated with liver and other organ damage. Levocarnitine is a drug used to provide extra carnitine. Laboratory and real-world usage of the dietary supplement levocarnitine suggests its potential to prevent or reduce liver toxicity from asparaginase. The overall goal of this study is to determine whether adding levocarnitine to standard of care chemotherapy will reduce the chance of developing severe liver damage from asparaginase chemotherapy in ALL, LL and/or MPAL patients.

This study is testing a new treatment called IR-TMS (image-guided, robot navigated transcranial magnetic stimulation) to see if it can help people who drink too much alcohol to reduce the amount they drink. Participants will be placed into one of three groups, each receiving a slightly different version of this treatment. The study involves going through a few sessions of IR-TMS, having brain scans (MRI), providing blood and urine samples, and answering questions about their drinking and mental health. These activities are part of the study and aren't usually part of regular treatment for alcohol use. IR-TMS is different from regular treatments like therapy or medication because it uses magnetic fields to target specific parts of the brain. The goal is to see if this treatment can help reduce the urge to drink. There are other options, like sticking with therapy or medication, which are less intense but have been used for a longer time.

This phase III trial compares the effectiveness of fractionated stereotactic radiosurgery (FSRS) to usual care stereotactic radiosurgery (SRS) in treating patients with cancer that has spread from where it first started to the brain. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. FSRS delivers a high dose of radiation to the tumor over 3 treatments. SRS is a type of external radiation therapy that uses special equipment to position the patient and precisely give a single large dose of radiation to a tumor. FSRS may be more effective compared to SRS in treating patients with cancer that has spread to the brain.

This phase III trial compares the effect of adding immunotherapy (brentuximab vedotin and nivolumab) to standard treatment (chemotherapy with or without radiation) to the standard treatment alone in improving survival in patients with stage I and II classical Hodgkin lymphoma. Brentuximab vedotin is in a class of medications called antibody-drug conjugates. It is made of a monoclonal antibody called brentuximab that is linked to a cytotoxic agent called vedotin. Brentuximab attaches to CD30 positive lymphoma cells in a targeted way and delivers vedotin to kill them. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs such as doxorubicin hydrochloride, bleomycin sulfate, vinblastine sulfate, dacarbazine, and procarbazine hydrochloride 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. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid (DNA) and may kill cancer cells. It may also lower the body's immune response. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill cancer cells. Vincristine is in a class of medications called vinca alkaloids. It works by stopping cancer cells from growing and dividing and may kill them. Prednisone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Adding immunotherapy to the standard treatment of chemotherapy with or without radiation may increase survival and/or fewer short-term or long-term side effects in patients with classical Hodgkin lymphoma compared to the standard treatment alone.

RYGB (roux-en-y gastric bypass) has been reported to reverse type 2 diabetes (T2DM) immediately after surgery before any significant weight loss. In addition, a growing number of patients have been recognized with life-threatening hyperinsulinemic hypoglycemia several years following their surgery. While the mechanisms by which RYGB improves glucose metabolism or alters islet cell function in patients after RYGB are not understood, recent studies suggest that increased secretion of GI hormones, primarily glucagon-like peptide 1 (GLP-1), as well as alteration in neural activity may contribute to enhanced insulin secretion in general, and to a greater extent in patients with hypoglycemia. The proposed research is designed to address the role of RYGB on insulin secretion by evaluating the contribution of stimulatory factors (neural and GI hormone) on islet cell function and the islet cell responsiveness to the physiologic stimulatory factors, in RYGB patients with and without hypoglycemia and non-operated controls.

After the removal of a tooth, a bone graft is often placed in the socket to try to keep the volume of bone that was there when the tooth was present so that the bone does not "shrink". The bone graft is sometimes kept in place with a small piece of material over the top of the tooth socket and with stitches. This procedure is called "Ridge Preservation". Many different materials are used for ridge preservation including bone allografts (bone grafts derived from a human tissue donor), bone xenografts (bone grafts derived from species other than humans, such as cows and pigs), and synthetic materials that are similar in structure to bone (such as calcium apatite). The bone allograft and the calcium apatite product used in this study are Food and Drug Administration (FDA) approved. This study will compare the two methods used to see how much new bone formation there is inside the tooth socket at about 16 weeks of healing after ridge preservation with a calcium apatite/collagen sponge versus an allograft.
