n helpful in the evaluation of these disorders but do not necessarily correlate well with objective testing, such as polysomnography and multiple sleep latency test and maintenance of wakefulness test.

Conclusions/Relevance: Subjective testing with tools, such as sleep logs and sleepiness scales, are often helpful in the evaluation of these disorders but do not necessarily correlate well with objective testing, such as polysomnography and multiple sleep latency test and maintenance of wakefulness test.

CYP3A4 catalyzes the rearrangement of the dual orexin receptor antagonist daridorexant to 4-hydroxy piperidinol metabolites - PubMed

CYP3A4 catalyzes the rearrangement of the dual orexin receptor antagonist daridorexant to 4-hydroxy piperidinol metabolites - PubMed

Source : https://pubmed.ncbi.nlm.nih.gov/36892179/

The dual orexin receptor antagonist daridorexant was approved in 2022 in the USA and EU for the treatment of insomnia. The purpose of this study was the identification of its...

Conclusions/Relevance: The proposed mechanism was substantiated using an N-methylated analogue, which might hydrolyze to the open-chain aldehyde but cannot undergo the final cyclization step. CYP3A4 was the major P450 enzyme responsible for daridorexant metabolism, accounting for 89 % of metabolic turnover.

What respiratory physicians should know about narcolepsy and other hypersomnias - PubMed

What respiratory physicians should know about narcolepsy and other hypersomnias - PubMed

Source : https://pubmed.ncbi.nlm.nih.gov/36865656/

Narcolepsy and related central disorders of hypersomnolence may present to the sleep clinic with excessive daytime sleepiness. A strong clinical suspicion and awareness of the diagnostic clues, such as cataplexy,...



Conclusions: Narcolepsy is a chronic, disabling neurological disorder characterised by daytime sleepiness and recurrent episodes of muscle weakness (cataplexy). It is an under-recognised and under-diagnosed condition with a mean interval of up to 15 years between first presentation to medical care and diagnosis. As narcolepsy is eminently...

Nocturnal sodium oxybate increases the anterior cingulate cortex magnetic resonance glutamate signal upon awakening - PubMed

Nocturnal sodium oxybate increases the anterior cingulate cortex magnetic resonance glutamate signal upon awakening - PubMed

Source : https://pubmed.ncbi.nlm.nih.gov/36869598/

Clinical guidelines recommend sodium oxybate (SXB; the sodium salt of γ-hydroxybutyrate) for the treatment of disturbed sleep and excessive daytime sleepiness in narcolepsy, yet the underlying mode of action is...

Conclusions: The data indicate that elevated glutamate in the ACC could provide a neurochemical mechanism underlying SXB's pro-vigilant efficacy in disorders of hypersomnolence.

Insomnia and impacts on facial expression recognition accuracy, intensity and speed: A meta-analysis - PubMed

Insomnia and impacts on facial expression recognition accuracy, intensity and speed: A meta-analysis - PubMed

Source : https://pubmed.ncbi.nlm.nih.gov/36870234/

Facial expressions provide nonverbal cues that are important for delivering and interpreting human emotions. Previous studies have shown that the ability to interpret facial emotions correctly could be partially impaired...


Conclusions: Impaired recognition accuracy and longer reaction times were identified in FER tasks among people with insomnia compared to the healthy controls.
