Menopause greatly increases cardiovascular disease risk (CVD). Current exercise guidelines are inadequate to ameliorate this risk and higher intensity exercise may be necessary for cardiovascular benefits in postmenopausal females. Oral nitrate supplementation enhances exercise performance and CVD risk profile in several clinical conditions. The investigators recently reported that 3-days of nitrate supplementation in postmenopausal females enhances acute post-exercise vascular function, in an intensity dependent manner. The effects of nitrate supplementation and exercise training over a longer training program remains unexplored. This investigation will examine the impact of exercise training intensity with and without inorganic nitrate supplementation, on CVD and fitness outcomes. Postmenopausal females will be tested for maximal oxygen uptake and lactate threshold before randomization to one of four groups: that inorganic nitrate-rich beetroot juice, or beetroot juice with nitrate extracted; and assigned to one-month of calorie matched high-intensity or moderate-intensity exercise training. Vascular function and fitness will be evaluated before and after training. Read Less

End-stage heart failure (HF) is a progressive illness with a mortality rate similar to most advanced cancers.Roughly 5% of patients with HF have end-stage disease that is refractory to medical therapy (stage D heart failure). When patients reach this point in their disease, the only treatments known to prolong life are cardiac transplantation or left ventricular assist devices. In patients who do not qualify for these options, or elect a palliative approach, inotropes are frequently used to improve hemodynamics through an increase in cardiac output and reduction in filling pressures. While inotropes provide profound symptomatic relief, these benefits are accompanied by significant risks of progressive adverse cardiac remodeling, arrhythmias, and sudden death. There is, therefore, an urgent need to develop strategies to reduce the dose or duration of inotrope use in the management of patients with stage D of HF. Read Less

This is a feasibility study to determine whether pulsed ultrasound stimulation targeting the splenic nerve or the cervical vagus nerve can elicit an anti-inflammatory immune response in healthy volunteers. Read Less

The purpose of this study is to estimate and compare the incidence of overall malignancy, serious infection, and opportunistic infections between new users of ustekinumab and new users of other biologic therapies among adult participants with Crohn's disease (CD) or ulcerative colitis (UC).

Metformin is the most prescribed blood sugar (glucose)-lowering medication for patients diagnosed with type 2 diabetes mellitus (T2DM). Metformin stimulates glucose uptake in skeletal muscle similar to the effects of exercise, though, some studies report that metformin may decrease exercise capacity. The main question this study looks to answer is: • Does metformin alter exercise capacity? Participants will: * Complete 5 exercise tests on a stationary bike. * Undergo a body composition test. * Take metformin and placebo. * Complete food and symptom logs. The researchers hypothesize that: • Metformin will reduce aerobic capacity. Read Less

Intermittent exotropia is difficult to treat. The mainstay of treatment involves surgery, and in one long-term study authors found that as many as 60% of IXT required at least one re-operation.Patching of the non-dominant eye has also been tested in a large, multi-center randomized control trial and was not found to have a large benefit. More non-surgical treatment modalities are critical to improve the care in this condition. Read Less

Lung transplantation (LT) is the only definitive therapy for many patients with end-stage lung diseases. The supply of donors' lungs is the biggest bottleneck to performing a lung transplant, and many patients die while waiting. Acute Cellular Rejection (ACR) is a significant risk factor for developing chronic allograft failure, a primary reason for death in this patient population. These observations highlight the importance of early diagnosis and management of ACR to prevent chronic graft failure. The preliminary results support the idea that Hyperpolarized Gas Magnetic Resonance Imaging has excellent potential to address this clinical gap. This study hypothesizes that optimized hyperpolarized gas magnetic resonance imaging (HGMRI) signatures can detect early pathophysiologic derangements in lung allografts consistent with ACR. This study also hypothesizes that the optimized HGMRI signatures will correlate with single-cell transcriptomic signatures that reflect dysregulated immune responses associated with ACR. Read Less

The purpose of this research is to see if combining gemcitabine, cisplatin and Durvalumab chemotherapy treatments with a direct tumor therapy called Yittrium-90, will work better together to shrink the tumor and control cancer. Read Less

Many combat veterans (c-Vs), service members (SMs) and civilians with mild traumatic brain injury (mTBI, also termed concussion) suffer from persistent post-concussion symptoms (PPCS) that degrade physical and cognitive well-being and have been linked with early neurodegeneration. PPCS include somatosensory (e.g., headache, disturbed vision), vestibular (e.g., dizzy, clumsy), cognitive (e.g., executive function, memory) and affective symptoms (e.g., sleep disturbance, irritability, depression). A key pathological process that provokes and perpetuates PPCS is autonomic nervous system (ANS) dysfunction such as unremitting sympathetic nervous system activation that also exacerbates other pathology such as inflammation. ANS activity can be readily quantified by measuring heart rate variability (HRV), or the variation in heart rate over time, which serves as a valid index of both physiological and psychological health Read Less

This study examines the bioavailability and bioequivalence of single dose of a Fixed Dose Combination (FDC) tablet (12 mg Extended-Release Torsemide and 15mg Spironolactone). The goal of this study is to determine PK/PD effects of the FDC, 10 mg Torsemide alone, 25mg Aldactone® (Spironolactone) alone, and 10 mg Torsemide and 25 mg Aldactone® (Spironolactone) taken together in healthy subjects.

Idiopathic pulmonary fibrosis has a poor prognosis with limited treatment options. The Investigator hypothesize hyperpolarized Xe129-MRI can be performed in patients with IPF and repeated over time which will detect deficiencies related to perfusion in the lung. Read Less
