GSK2578215A As a result, female individuals with OSA were often under-diagnosed and under-treated compared with male individuals. However, recent data suggest that several OSA-associated adverse cardiovascular outcomes are more pronounced in women. This review provides a summary of the most relevant recent evidence with regard to sex-specific OSA characteristics, including atypical symptoms, greater quality of life impairment and several more pronounced adverse outcomes in female individuals compared with male individuals. It also provides updated evidence on the influence of female gender on under-treatment of OSA with limited evidence supporting gender differences in the effects of OSA treatment. There is evidence suggesting gender-based differences in the frequency, severity, clinical presentation, and outcomes of OSA. The recognition of these gender differences could improve screening with development of female-specific screening instruments, early diagnosis, and individualized therapeutic plans towards better disease management and its outcomes.There is evidence suggesting gender-based differences in the frequency, severity, clinical presentation, and outcomes of OSA. The recognition of these gender differences could improve screening with development of female-specific screening instruments, early diagnosis, and individualized therapeutic plans towards better disease management and its outcomes. The purpose of this review is to describe the variability of obstructive sleep apnea (OSA), both from a standpoint of underlying mechanisms and in terms of clinical manifestations. Recent data suggest that not all patients with sleep apnea get their disease for the same reason. As such, no one variable is effective at defining which patients do or do not have sleep apnea. Identifying the mechanism(s) underlying OSA for an individual is helpful as it can help to determine whether personalized therapy could be developed based on an individual's characteristics. In addition, these underlying mechanisms may be helpful in predicting response to therapy and prognosticating regarding future complications. OSA is a heterogeneous disease with highly varying underlying mechanisms. OSA has variable clinical manifestations with definable subsets having risk of particular complications. Future studies will be helpful to identify mechanisms underlying OSA using clinically accessible tools and then using these data to focus individualized treatment approaches.OSA is a heterogeneous disease with highly varying underlying mechanisms.

Future studies will be helpful to identify mechanisms underlying OSA using clinically accessible tools and then using these data to focus individualized treatment approaches. The purpose of this article is to highlight recent advances in the burgeoning field of drug-induced sleep endoscopy (DISE). One of the first studies to investigate the correlation of DISE findings and natural sleep endoscopy found good agreement in clinically significant obstruction. Previous studies have shown good agreement of DISE findings with the use of different sedative agents implying that the choice of sedative may not be crucial. However, recent studies show variable patterns of collapse, especially at the tongue base, with the use of different sedative agents. A universally accepted classification scheme for drug-induced sleep endoscopy is lacking. A new DISE classification system, termed Palate, Tonsils, Lateral pharyngeal wall, Tongue base, Epiglottis, was introduced this year with the noted advantage of being able to better differentiate between clinically relevant tonsillar and lateral pharyngeal wall collapse. Despite recent advances in the field, there remains no general consensus that DISE findings predict surgical success but may aid in the identification of patients who will respond well to oral appliance therapy. Drug-induced sleep endoscopy is a structure-based evaluation of the upper airway that more closely resembles the natural sleep state compared with awake evaluation.Drug-induced sleep endoscopy is a structure-based evaluation of the upper airway that more closely resembles the natural sleep state compared with awake evaluation. Insomnia and hypersomnia are conditions with multifactorial causes that can be difficult to treat. There have been recent developments and changes in the treatment of both conditions, including the addition of some agents that have a novel mechanism of action. This review summarizes recent changes and highlights pertinent updates. Benzodiazepine receptor agonists received a warning in 2019 regarding the possibility of complex sleep behaviors, such as sleepwalking. Zolpidem has been marketed in new dosage forms that include sublingual tablets and oral spray formulations. Orexin receptor antagonists appear to be well tolerated with a good safety profile. Suvorexant received an approval for the treatment of patients with comorbid insomnia and dementia. Lemborexant was demonstrated to be effective for maintenance insomnia. Trazodone was shown to affect the oligomerization of tau proteins thus suggesting potential implications in attenuating dementia pathology. Pitolisant, a novel histamine-3 receptor antagonits. Novel agents also are available for hypersomnia and there are options beyond traditional stimulants that may have great utility.
