PANTHER Study: Puberty, Diabetes, and the Kidneys, When Eustress Becomes Distress
Early diabetic kidney disease (DKD) occurs in 50-70% of youth with type 2 diabetes (T2D) and confers high lifetime risk of dialysis and premature death. Youth-…
Structural Modification In Supraglottic Airway Device Enhances Exchange Between Supraglottic & Endotracheal Ventilation Modes
The proposed A/Z modification of a supraglottic airway (SGA) incorporates an opening in the SGA body that enables access to the endotracheal tube (ETT) through…
Fetal Cerebrovascular Autoregulation in Congenital Heart Disease and Association With Neonatal Neurobehavior
Determine 1) the impact of abnormal fetal cerebrovascular physiology with neurodevelopmental delay (ND) outcomes and 2) how this relationship is modified by pa…
Optimizing Care in Critically Ill at UCHealth by Liberalizing the Target O2 in Mechanically-ventilated ICU Patients
A multimodal educational intervention to target an oxygen saturation target range (SpO2 90-96%) will reduce ventilator length of stay and reduce occult hypoxem…
Hypoxia and Hemodilution Testing in Healthy Adult Volunteers
This study will collect physiological measurements in healthy adult volunteers under controlled hypoxia and hemodilution conditions.
