Summary: This study aimed to evaluate the plasma concentration of electrolytes and their impact on the intensity of sleep bruxism (SB) and blood pressure variability. The results showed a lower plasma sodium concentration in patients with SB, which was associated with increased blood pressure variability.

Summary: The aim of this study was to examine sleep disturbances in children with ADHD compared to their typically developing peers after controlling for moderating variables. The results showed that children with ADHD had higher rates of sleep disturbances and disorders compared to the control group.

Summary: A 50-year-old patient with epilepsy, hypertension, loud snoring, recent 50-lb weight gain, and abrupt awakenings with a feeling of breathlessness but no headaches or excessive daytime sleepiness presented with concerns. What would you do next?

Summary: This study found significant differences in EEG spectral powers among non-OSA participants and those with different severities of OSA, particularly in the beta and sigma bands. After controlling for confounding factors, it was discovered that OSA patients had higher beta power and lower sigma power, with beta power decreasing as the severity of OSA increased.

Summary: Obstructive sleep apnea (OSA) is a highly prevalent condition worldwide and if left untreated, it can lead to multiple medical complications and a decreased quality of life. Using total bed time instead of total sleep time to quantify OSA severity may underestimate the severity of the disease. A study found that risk factors for underestimating OSA severity include age and body-mass index.

Summary: A task force evaluated the American Academy of Sleep Medicine's clinical practice guideline on the treatment of adult obstructive sleep apnea. The guideline was found to be relevant and applicable to the practice of sleep medicine in various regions of the world, with caveats for universal applicability.

Summary: Despite its importance to health and quality of life, pediatric sleep, along with sufficient clinical data, remains poorly understood. To address this issue, the Nationwide Children's Hospital (NCH) Sleep DataBank was created, providing a large-scale sleep dataset focused on pediatric patients, collected in a clinical setting. This valuable resource has the potential to advance research in automatic sleep scoring and real-time sleep disorder prediction.

Summary: This study found that Indigenous Australian children have issues with sleep quality, including a higher prevalence and severity of obstructive sleep apnoea, higher daytime sleepiness scores, later bedtimes, and reduced total sleep time compared to their non-Indigenous peers.

Summary: This study analyzed one-night sleep recordings from 852 subjects in Uppsala, Sweden, and found that there were differences in sleep patterns during different phases of the lunar cycle. Men showed shorter sleep duration and lower sleep efficiency during the waxing period compared to the waning period.

Summary: The study confirmed the validity of the French version of the SPAQ, which has a two-factor structure. Mood and social activity were significantly affected by seasons in the depressed/bipolar group, and a stronger seasonal score was associated with more severe phenotypes of depression and mania.

Summary: This paper first introduces the basic knowledge and significance of sleep monitoring. Then, it describes the research progress of bioelectrical, biomechanical, and biochemical signals used for sleep monitoring based on the types of physiological signals monitored. Since monitoring sleep quality based on only one signal is not ideal, this paper also reviews the research on multi-signal monitoring and introduces systematic sleep monitoring schemes. Finally, a conclusion and discussion of sleep monitoring are presented to propose potential future directions and prospects for sleep monitoring.

Summary: The aim of this study was to compare the sleep electroencephalogram of children with different intellectual profiles. Children were divided into groups based on their Wechsler Intelligence Scale for Children (WISC) scores. The results showed that children with high IQ had more REM sleep and higher power in slow-frequency bands during REM sleep compared to children with normal IQ. The relationship between spectral power and WISC scores varied between different frequency bands and the two groups. These findings suggest that there may be functional differences in brain activity related to cognitive efficiency between children with different intellectual profiles.

Summary: This study explored the association between sleep stage dissociation and REM sleep instability with neurocognitive functioning in medicated patients with schizophrenia. The research found an inverse correlation between RSWA and neurocognitive composite score, indicating that RSWA might be a potential treatment target for improving cognitive impairment in patients with schizophrenia.

Summary: Recent literature has shown an association between short sleep duration, shift work, and obstructive sleep apnea with hypertension risk and blood pressure levels, with shift work potentially exacerbating the effects of short sleep on blood pressure. Continuous positive airway pressure treatment may improve blood pressure control in patients with hypertension. Efforts in educating patients and healthcare providers on the importance of identifying and treating sleep disturbances for hypertension prevention and management are crucial for advancing this research area.

Summary: In chronic stroke patients, 57% had undiagnosed moderate-severe obstructive sleep apnea and exhibited reduced slow-wave sleep with potentially compensatory increases in NREM 1-2 sleep compared to controls. Formal sleep studies are necessary after stroke, even in the absence of self-reported history of sleep-wake pathology.
