If the Krystal et al (2003) trial had used the WASO >30 minute criteria, which is standard for insomnia research, then approximately 40% of participants would have been excluded from the original study.
Specifically, the typical primary insomnia patient reports decreases in sleep onset latency and wake time after sleep onset below or near the 30-minute criteria commonly used to diagnose insomnia (Morin et al 1999).
During the study period, SBT was conducted on a T-piece for 60 minutes, and criteria for SBT were as follows: reliable respiratory drive, stable hemodynamics, improvement of the cause of respiratory failure, positive end-expiratory pressure 8 or less cmH2O, fraction of inspired oxygen 40% or less, and rapid shallow breathing index <200/min/L.
Likewise, patients undergoing weaning from mechanical ventilation can be tachypneic; the authors used a respiratory rate as high as 35 respirations per minute as a criterion for a failed spontaneous breathing trial (SBT), and such respiratory rates are obviously outside the range (0.15 to 0.4 Hz) chosen to compute HF HRV.
AIC=akaike information criteria; min= minute; [18F]FMISO=[18F]fluoromisonidazole; PET=positron emission tomography; CRT=chemoradiotherapy; ROI=region of interest; TAC=time activity curve; h=hour; CT=computed tomography.
Throughout the recording sessions, RAs assign sleep state codes (quiet sleep, active sleep, indeterminate, awake, cry) once each minute, based on behavioral criteria previously shown appropriate for prematurely born infants [ 71].
The validity of the estimated MVPA MET-minutes and vigorous MET-minutes was examined against a criterion of hand grip strength measured in kg using a hydraulic hand dynamometer (Fabrication Enterprises Inc., Irvington NY 10533, USA).
France is one of the few countries that provide permanent research positions following a 30-minute interview (other criteria such as publication record are, of course, also considered).
After three cycles of treatment, the patient developed stabbing pain localized behind her left eye with autonomic signs, spreading to the left side of the head, recurring 3-4 times per day and lasting 60-120 minutes, fulfilling diagnostic criteria for CH.
In accordance with the Active Australia Survey scoring criteria, minutes spent in 'vigorous' activity are doubled.
