NCT02404623
This trial objective is to assess whether doubling the daily intake of vitamin D improves serum vitamin D levels and serves as primary prevention of respiratory infections and asthma in premature infants. This is a prospective randomized (1:1) double-blinded trial. The study population will be randomized into two groups (1:1): * Intervention Group - 800 IU of Vitamin D once daily * Control Group - 400 IU of Vitamin D once daily Patients will be followed up for one year after randomization for serum Vitamin D levels and respiratory morbidity.
NCT01280942
The goal is to develop a two-tiered monitoring system to improve the care of patients at risk for clinical deterioration on general hospital wards (GHWs) at Barnes-Jewish Hospital (BJH). The investigators hypothesize that the use of an automated early warning system (EWS) that identifies patients at risk of clinical deterioration, with notification of nurses on the GHWs when patients are identified, will reduce the risk of ICU transfer or death within 24 hrs of an alert. As a substudy, the investigators will pilot the use of a wireless pulse oximeter to establish feasibility and to develop algorithms for a real-time event detection system (RDS) in these high-risk patients.
