NCT03002688
The purpose is to gauge the patients' level of comfort and anxiety for sequential cataract surgeries to assess if the second experience of cataract surgery differs from the initial experience.
NCT02053012
The investigators feel that children who have OSA or sleep-disordered breathing may have a different reaction time than normal variants. Children who have OSA are known to have behavioral and sleep patterns that are different. It makes sense their reaction time may be different than normal as well. We plan to measure reaction times via a 10 minute psychomotor vigilance test device in children who snore who are coming in for a sleep study or for adenotonsillectomy.
NCT00921011
The study hypothesis (or theory) is that monthly loss of iron before menopause may reduce women's risk of hardening of the arteries, or atherosclerosis. This study uses noninvasive, noncontrast magnetic resonance imaging (MRI) of arteries in women entering menopause. This will help to determine if there is a correlation between iron accumulation and hardening of the arteries. In addition, blood levels of hormones will be measured to help show differences due to hormone levels vs. iron accumulation.
NCT00987714
The objective of this study is to determine whether protocol guided resuscitation of brain dead organ donors using Pulse Pressure Variation (PPV) will increase the number of organs transplanted per donor. Specifically the study aims to: 1. improve resuscitation of potential organ donors. 2. improve organ function in donors. 3. increase organ recovery per donor. The investigators will randomize 960 subjects to either protocolized resuscitation (n=480) using a consensus-based PPV-guided algorithm or usual care using a 1:1 randomization scheme. The primary outcome is the mean number of organs transplanted per donor. Secondary outcomes include 6mHFS (six-month hospital-free survival) in the recipients, and mean number of organs procured per donor that are suitable for transplantation (intention to transplant). The study is powered to detect a 0.5 organ increase for transplantation per donor.
