Early Neurovascular Adaptations in Aging Women

Our goal is to enhance our understanding of early vascular adaptations in aging women with an emphasis on the sympathetic nervous system.

Glucose Levels as a Biomarker for Stress in Firefighters

Stress is known to cause physical structures in the brain to dysregulate, resulting in health problems like cancer, cardiac disease, metabolic disorders (obesity), and depression. Firefighters experience many of these diseases at higher rates than other occupations while also experiencing highly unique stress loads. When the body's nervous system responds to stress, blood glucose levels increase. This study will equip firefighters with continuous glucometers to observe glucose levels during emergency response and other stressful events. The immediate goal of this study is to determine whether the physiological stress response of on-shift firefighters can be quantified with glucose monitoring. The long-term goal is to identify occupational firefighter stress as a health risk exposure.

Sympathetic Activity in Post-injury Outcomes: Impact on Sleep and caRdiovascular Health InvesTigation

The goal of this observational study is to learn about the long-term health of United States military service members who were injured during combat. The main questions it aims to examine are: * How does the severity of a combat injury impact 1) cardiovascular risk, 2) the sympathetic nervous system and arrhythmias, 3) blood pressure, and 4) sleep disorders? * Are self-reported mental health symptoms related to sympathetic nervous system hyperactivity, sleep disorders, and cardiovascular risk in combat-injured service members? This study will recruit from a sample of participants in another research study called the Wounded Warrior Recovery Project (WWRP) who 1) agreed to be contacted about future research studies and 2) have a record of a combat injury within the Injury Severity Score ranges required for this study. Participants will: * Provide demographic information and a medical history review * Visit a local laboratory for biometrics measurements and to provide blood and urine samples * Wear an ambulatory electrocardiogram monitor for 24 hours per day for seven consecutive days * Wear a home sleep test monitoring device for one night * Wear a blood pressure monitor for 24 consecutive hours on the day after the home sleep test At the end of the study, participants will be asked to mail back the home sleep test and blood pressure monitors. Prepaid package materials will be provided.

Comparison of Surgical Outcomes Between Pre Sympathetic Plexus and Post Sympathetic Plexus Approach

There would be no difference in the risk of sympathetic plexus damage between the pre sympathetic plexus approach and the post sympathetic plexus approach.
