Gamma Power of Electroencephalogram Arousal is Modulated by Respiratory Event Type and Severity in Obstructive Sleep Apnea
This work investigated breathing obstruction-related arousal intensity via high-frequency spectral content in nocturnal electroencephalogram (EEG). Gamma band (30–40 Hz) power in EEG was studied during arousals caused by different respiratory events in 869 patients with suspected obstructive sleep apnea (OSA). Arousal gamma power was higher in deeper sleep and increased alongside the respiratory event severity. As elevated gamma activity could indicate a greater shift towards wakefulness, the results illustrate that the magnitude of sleep disruption might vary depending on the respiratory event characteristics. These findings can bring more insight into respiratory event-related sleep fragmentation in OSA severity assessment... Read more

Radial Pulse Spectrum Analysis as Risk Markers to Improve the Risk Stratification of Silent Myocardial Ischemia in Type 2 Diabetic Patients
      Diabetic patients with silent myocardial ischemia (SMI) have elevated rates of morbidity and mortality and need intensive care and monitoring. An early predictor of SMI may lead to early diagnosis and medical treatment to prevent progression and adverse clinical events.... Read more
