NCT05046353
Schizophrenia is a major public health problem associated with cognitive deficits, such as short and long term memory, executive functioning, attention and speed of processing that are amongst the strongest predictors of impaired functional outcome. In addition, schizophrenia patients show reduced "plasticity", defined as reduced learning. D-serine is a naturally occurring activator of the N-methyl-d-aspartate-type glutamate receptors (NMDAR) in the brain, and this project will assess the D-serine treatment over 16 weeks of a program designed to measure auditory plasticity.
NCT04170894
This study seeks to assess the effect of apnea (breath hold) during atrial fibrillation (AF) ablation by having all ablations performed under apnea. By prospectively studying the effects of apnea on AF ablation, the investigators wish to demonstrate its feasibility, safety and impact on patient outcomes. This is a prospective study that includes both an apnea arm and a control arm. The subjects who consent to the apnea arm will undergo an atrial fibrillation ablation with periods of apnea. The subjects who consent to the control arm will agree to have their data from their standard of care atrial fibrillation be collected for comparison.
