This study is testing whether a medicine called metformin can help treat aortic aneurisms in the abdomen. The study will use imaging tests to examine whether metformin can help prevent these aortic aneurisms from getting bigger. To participate in this study, you must be 55 to 90 years old and diagnosed with an abdominal aortic aneurism. This study takes place in Stanford, California.

The study is to investigate that the worsening orthostatic tachycardia and symptoms after glucose ingestion in POTS patients are due to a greater increase in splanchnic venous capacitance and excessive blood pooling during an orthostatic challenge.

Are you or a loved one on a ventilator in the hospital in Minnesota? This study is finding out whether people who are on a ventilator sleep better and have less anxiety if they can control their own sedation medicine. To participate in this study, you must be at least 18 years old and receiving mechanical ventilation while hospitalized. This study is located in Minneapolis and Rochester, Minnesota.

Do you or a loved one have pneumonia? This study will test whether combining two medicines to reduce inflammation of the airway and to keep it open may help prevent respiratory failure in people who have pneumonia. To participate in this study, you must be at least 18 years old and have severe pneumonia with low blood oxygen levels.

Is your child on a ventilator at Children’s Hospital Los Angeles? Ventilators can sometimes weaken the muscles around the lungs, especially in children. This study is testing whether a new computer method to control ventilators can help prevent muscle weakness in children. To participate in this study, your child must be between 1 month and 18 years old and have been on a ventilator for less than 48 hours (or 72 if they were transferred from another hospital) because of a serious lung disease. This study is located in Los Angeles, California.

Are you being treated in the ICU for acute respiratory failure? This study is looking at whether treating depression along with physical therapy helps people recover faster from respiratory failure. After leaving the ICU, you will be visited at your home by a physical therapist and occupational therapist who will talk to you about your goals for recovery and what activities you value the most. They will then design a plan for you that includes a type of talk therapy for depression called behavioral activation. To participate in this study, you must be at least 18 years old and undergoing treatment for acute respiratory failure for more than 24 hours in the ICU. This study is located in Baltimore, Maryland.

his trial will evaluate an oral drug discovered in a high throughput screen, which increases fetal globin protein (HbF and red blood cells expressing HbF)and messenger ribonucleic acid (mRNA) to high levels in anemic nonhuman primates and in transgenic mice.

Sickle Cell Disease (SCD) impairs oxygen transport to tissue and causes endothelial injury. Thus, therapeutic interventions aim to improve both, but there is an unmet need for biomarkers to determine when intervention is necessary and evaluate the effectiveness of the chosen intervention in individual patients. This study proposes to monitor SCD and its treatment through their impact on cerebral hemodynamics, as the brain is one of the most vulnerable and consequential targets of the disease. Specifically, this study will optimize quantitative magnetic resonance imaging (MRI) and advanced optical spectroscopy techniques such as frequency-domain near-infrared and diffuse correlation spectroscopies (FDNIRS-DCS) to monitor 1) cerebral oxygen transport with measures of cerebral blood flow (CBF), cerebral oxygen extraction fraction (OEF) and cerebral metabolic rate of oxygen consumption (CMRO2) and 2) endothelial function with cerebrovascular reactivity (CVR).
