Purpose: We hypothesized that diurnal intermittent fasting would not increase slow frequency EEG waves, which reflect increased sleepiness. Therefore, this study aimed at performing a quantitative EEG analysis of young healthy volunteers with and without diurnal intermittent fasting while controlling for potential confounders.

Methods: Eight young healthy volunteers (mean age: 24.4 ± 3.7 years) reported to the laboratory during the following five occasions: (1) adaptation, (2) 4 weeks before Ramadan while performing diurnal intermittent fasting (fasting from dawn to sunset) for 1 week (fasting outside Ramadan), (3) 1 week before Ramadan (nonfasting baseline), (4) during the second week of Ramadan while fasting (Ramadan), and (5) 2 weeks after Ramadan (recovery). Frontal, central, and occipital EEG signals were monitored four times (09:15, 11:15, 13:15, and 15:15 for 15 minutes each time) while the participants were awake to assess EEG spectral power of the delta, theta, alpha, and beta frequency bands.

Results: During wakefulness, no difference in EEG slowing was observed between nonfasting baseline and fasting during and outside Ramadan. There were no differences in the mean absolute power of each band in any studied brain region in any of the four study periods. Moreover, there was no difference in EEG absolute powers in the delta, theta, alpha, and beta frequency bands for any individual brain region during the four study periods.

Conclusions: Spectral analysis of EEG power indicates that diurnal intermittent fasting does not increase sleepiness. Future larger studies are needed to confirm the current findings.

Objectives: Evaluate diabetic patients' knowledge, practices, and the prevalence of complications during Ramadan fasting (RF) before and after an education program.

Methods: We conducted a prospective study including 140 consecutive diabetic patients (DP) who intended to observe RF in 2023. Patients underwent a questionnaire and received pre-Ramadan education (PRE) according to the IDF-DAR 2021 recommendations.

The Effects of Nocturnal Hypoxemia on Cognitive Performance in Andean Highlanders.

High Alt Med Biol

December 2024

Division of Pulmonary, Critical Care, Sleep Medicine, and Physiology, Department of Medicine, University of California, San Diego, California, USA.

Many Andean highlanders exposed to chronic hypoxemia are susceptible to excessive erythrocytosis (EE) and chronic mountain sickness (CMS). Nocturnal hypoxemia is more marked than diurnal hypoxemia and includes sustained and intermittent components. The potential for cognitive impairments related to nocturnal hypoxemia in this population has not been extensively studied, but improved understanding may provide opportunities for the prevention of long-term effects of EE and CMS.

Retinal rods and cones underlie scotopic and photopic vision, respectively. Their pigments exhibit spontaneous isomerizations (quantal noise) in darkness due to intrinsic thermal energy. This quantal noise, albeit exceedingly low in rods, dictates the light threshold for scotopic vision.

Introduction: Over half of patients who spend >48 hours in the intensive care unit (ICU) are fed via a nasogastric (NG) tube. Current guidance recommends continuous delivery of feed throughout the day and night. Emerging evidence from healthy human studies shows that NG feeding in an intermittent pattern (rather than continuous) promotes phasic hormonal, digestive and metabolic responses that are important for effective nutrition.

Article Synopsis
  • The study analyzed data from 93 participants with type 1 diabetes to explore how the frequency of scanning with intermittent-scanning continuous glucose monitoring (isCGM) affects time in range (TIR), time above range (TAR), and time below range (TBR) throughout the day.
  • Increased scanning frequency was linked to higher TIR, particularly in the afternoon, evening, and night, and was associated with lower TAR and TBR during these times.
  • Psychological factors, such as concerns about blood glucose levels affecting social interactions and feelings of loneliness, were found to influence how often participants scanned their glucose levels.
