There is need for a whole blood analog for use when banked blood is unavailable or undesirable. In civilian trauma, hemorrhage accounts for ~ 35% of pre-hospital deaths; moreover, ~ 20% of military casualties are in hemorrhagic shock on arrival to field hospitals and an additional 5% require urgent transfusion. A recent review concluded that hemorrhage accounted for ~ 90% of potentially survivable battlefield deaths - lives that could be saved with better hemorrhage control capabilities and improved, field-ready blood, blood components, or blood substitutes. While study of ideal composition for resuscitative fluids is ongoing, it is evident that for those in hemorrhagic shock, volume replenishment alone (without O2 carrying capacity) is insufficient. Alternatively, with massive blood loss or with ongoing bleeding from non-compressible injuries, resuscitation with an O2 carrier alone may be complicated by acquired coagulopathy (either dilutional or trauma-induced). Development of a balanced resuscitation fluid that treats both shock and coagulopathy (comprising a field-deployable O2 carrier with lyophilized humoral hemostatic components and platelets) is essential to allow on-scene treatment during the critical 'golden-hours' after injury. As such, the whole blood analog described herein could be this product, thus transforming care in both civilian and military settings.The scientific purpose of this study is to develop a combined whole blood substitute from individual artificial prototypes that have been separately developed for each blood component (i.e., combining an artificial oxygen carrier, with an artificial plasma analogue and an artificial platelet analogue). Together, these combined components will recapitulate the composition and performance of natural whole blood. Blending and combination experiments of the individual artificial prototypes will be performed to test compatibility and optimize efficacy. State of the art in vitro (bench top) assays will be performed to assess physicochemical and functional performance (hemodynamics, oxygen delivery, hemostasis), with data being compared to experiments performed on fresh and stored whole blood.

The investigators will perform follow-up on 250 of 500 cases recruited into the ROSE study of cases with deep and lobar intracerebral hemorrhage to perform advanced neuroimaging at 12-24 months post stroke, and evaluations of motor and cognitive function at baseline, 6 months after baseline, and 12 months after baseline to determine predictors of recovery, progressive cognitive or functional impairment. The investigators propose to leverage the recruitment, DNA, RNA-seq and baseline advanced neuroimaging cohort of ROSE to obtain long-term neuroimaging and identical assessments longitudinally to address critical questions regarding the progressive decline of patients 12 to 24 months post intracerebral hemorrhage (ICH) with long term cognitive follow-up to 36 months on average. This proposal would represent the largest, and longest advanced neuroimaging and RNA-sequencing evaluation after ICH to date.

More than three quarter of patients with breast cancer are treated by hormone pills called tamoxifen and aromatase inhibitors (AIs). AIs are drugs that stop female hormone production. This hormone production mostly happens in fat, muscle, and breast tissue in postmenopausal women. The female hormone estrogen is an important hormone for the growth of breast cancer cells. Anastrozole (Arimidex®) and Letrozole (Femara®) are AIs that are approved by the Food and Drug Administration (FDA). They have been used since 2005 to treat women with early stage breast cancer. When given before surgery (neoadjuvant), both anastrozole and letrozole have been shown to successfully shrink breast cancer tumors in most patients. In over 50% of patients, anastrozole and letrozole when given for about 4 months also helped to improve surgery outcomes. On top of that, whether or not a patient responds to anastrozole and letrozole before surgery can help the doctor decide whether that patient needs additional chemotherapy. One of the things may influence the level of hormone is body weight. It has been previously shown that postmenopausal women with higher body fat have higher level of female hormone as well as an increased risk of breast cancer. This is likely due to an increase in aromatase activity in the fatty tissue. However, at the current time AIs are used at the same doses in all women with breast cancer no matter whether they have different body weight. Currently, we do not know for certain whether the same doses of AIs work as well in patients with higher body fat compared to patients with less body fat. The purpose of this study is to see if women with higher body fat respond differently to AI treatment compared to women with lower body fat.

Biomarkers for Vascular Contributions to Cognitive Impairment and Dementia (MarkVCID) is an NIH-funded consortium dedicated to finding biomarkers involved in age-related thinking and memory problems. Alzheimer's disease and other dementias leave signatures on brain scans or in the blood called biomarkers. The MarkVCID study will measure a panel of candidate biomarkers in 1800 participants and watch them closely to see what they tell us about changes in brain function and risk of memory loss. Age-related problems in thinking and memory represent some of the greatest risks to public health in the US and globally. Diseases that affect small blood vessels in the brain have been shown to be major contributors to these changes. However, research and patient care can be held back by limited biomarkers that identify who should be treated. The MarkVCID Consortium includes 17 US medical centers, a Coordinating Center, an External Advisory Committee, and NIH leadership. Data and biospecimens collected as part of this research study will be stored in a research database and biorepositories, so that researchers can use this information to study brain function.

The goal of this pragmatic cluster-randomized crossover trial is to test if less unnecessary antibiotics are prescribed when the lab reports respiratory culture test results in a specific way for patients who have respiratory cultures obtained, but do not meet clinical criteria for ventilator associated pneumonia (VAP). The main question it aims to answer is: Does a modified culture reporting intervention reduce unnecessary antibiotics for ventilated patients in the intensive care unit (ICU)? Researchers will compare antibiotic use outcomes between eligible patients whose test results are communicated using the modified reporting and those with standard reporting of results.

Aerobic exercise and physical activity improve patient health in patients in a variety of aspects of life and disease. It also improves patients' mental well-being and quality of life. However, the safety of this physical activity and its potential benefits remain uncertain for patients after aortic dissection, a tear in the main blood vessel delivering blood to all of the body's organs. The goal of this study is to facilitate the translation of pre-clinical findings by the Principal Investigator and published literature that demonstrates light to moderate exercise is safe and beneficial in patients with thoracic aortic dissection. This will be accomplished by using both imaging-based analyses of aortic wall responses to a 3- month exercise program, patient surveys of quality of life metrics, functional fitness assessments, and clinical outcomes.
