The goal of this clinical trial is to compare the combination of Massed Prolonged Exposure (PE); a behavioral therapy for PTSD) and a stellate ganglion block (SGB; an injection of a local anesthetic into the front of the neck) with Massed Prolonged Exposure and a sham injection in a sample of military service members or retirees with PTSD. The main questions it aims to answer are: (1) Does the addition of an SGB improve treatment outcomes associated with Massed PE and (2) Do differences in psychophysiological arousal during the exposure portion of treatment help explain treatment outcomes for PTSD. Participants will receive ten 90-minute session of Massed PE. Between the first and second Massed PE sessions, half of the participants will receive a SGB, and half will receive a sham SGB.

This phase III trial compares the effect of adding levocarnitine to standard chemotherapy 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 phase III trial compares the addition of stereotactic radiosurgery before or after surgery in treating patients with cancer that has spread to the brain (brain metastases). Stereotactic radiosurgery is a type of radiation therapy that delivers a high dose of radiation only to the small areas of cancer in the brain and avoids the surrounding normal brain tissue. Surgery and radiation may stop the tumor from growing for a few months or longer and may reduce symptoms of brain metastases.

Rhabdomyosarcoma is a type of cancer that occurs in the soft tissues in the body. This phase III trial aims to maintain excellent outcomes in patients with very low risk rhabdomyosarcoma (VLR-RMS) while decreasing the burden of therapy using treatment with 24 weeks of vincristine and dactinomycin (VA) and examines the use of centralized molecular risk stratification in the treatment of rhabdomyosarcoma. Another aim of the study it to find out how well patients with low risk rhabdomyosarcoma (LR-RMS) respond to standard chemotherapy when patients with VLR-RMS and patients who have rhabdomyosarcoma with DNA mutations get separate treatment. Finally, this study examines the effect of therapy intensification in patients who have RMS cancer with DNA mutations to see if their outcomes can be improved.

This project is a 2-phase, randomized clinical trial that includes 7 days of unilateral leg disuse (Phase 1), immediately followed by 14 days 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.

Psychiatric distress caused by PTSD may increase attention toward tinnitus, as well as perceived loudness and discomfort. It is important to understand how tinnitus-related distress and PTSD negatively interact together, in order to develop more effective therapeutic approaches. Understanding symptoms and neurobiological mechanisms using functional magnetic resonance imaging (fMRI), can lead to the necessary knowledge to develop effective interventions for individuals who suffer from both conditions.

Purpose is to identify if misoprostol in addition to local vasopressin decreases blood loss when compared to vasopressin alone, which is our current practice at this time. The study will be double-blinded with neither the patient nor the researcher knowing whether the placebo or the misoprostol was given. We will monitor patients for decrease in hemoglobin and hematocrit, need for transfusion, and operative time among other measures of perioperative morbidity to see if the addition of misoprostol makes a significant difference. We will also observe patients to see if there are any side effects of misoprostol that make its use undesirable.

The goal of this study is to measure survival rates associated with patients presenting in cardiac arrest based on their electrocardiographic rhythm and their echocardiographic rhythm. Electrocardiographic rhythm is defined as the rhythm on the ECG and echocardiographic rhythm is the rhythm visualized on bedside ultrasound. Specifically, we will categorize patients based on identical rhythms and dichotomous rhythms with an interest in outcomes in the patient group where their echocardiographic and electrographic rhythms do not match. This is important as current ACLS protocols use electrocardiographic rhythms to determine therapy but limited research implies that therapeutic decisions based on echocardiographic rhythm may produce increased survival. This study will occur during emergency department resuscitation of patients presenting in cardiac arrest. Patients presenting to the emergency department after cardiac arrest will undergo standard resuscitation based on ACLS protocols. Ultrasound imaging will be performed as soon as possible after the patient arrives and digitally recorded, as is currently the standard of care at the institute. Simultaneous recording of the ECG rhythm strip will occur as well. This will be repeated for as many pauses in CPR as is warranted. Each site will record data based on the Utstein nomenclature including patient demographics, arrest details and survival outcomes. Ultrasound images and ECG recordings will be de-identified and submitted to a central database. Data will be uploaded into a centralized database. Statistical analysis will analyze outcomes based on echocardiographic and sonographic findings. Our aim is to measure the survival benefit of treating out of hospital cardiac arrest using echocardiographic rhythm instead of electrocardiographic rhythm.
