The objective was to assess the role of pathological changes in cerebral hemodynamics in obstructive sleep apnea comorbid obesity patients in premature aging. Concentric-eccentric remodeling of the common carotid artery wall, hyperconstrictor variant of cerebral angiopathy, depletion of compensatory mechanisms of cerebral blood flow autoregulation, restriction of hemodynamic reserve with narrowing of the «corridor» of admissible changes in cerebral perfusion in patients with respiratory disturbances comorbid obesity. The biological age of sleep apnea patients exceeded the passport age by 41,3%, and comorbid patients by 49,6%. The most significant predictors of premature aging in both groups are cerebral hemodynamic indicators, reflecting the structural and geometric characteristics of the vessels, in particular, the thickness of the intima-media complex of the common carotid artery, as well as microvasculature reactivity indicators. In comorbid individuals, an additional marker of early aging may be the cerebral blood flow index. Patients with sleep apnea and obesity are characterized by accelerated rates of aging. Indicators of cerebral hemodynamics can be considered as markers of premature aging.

Association between sleep problems during pregnancy and postpartum depressive symptoms as well as condition of newborn at delivery.
J Obstet Gynaecol Res

Background: Pregnancy-related anatomic, physiologic, and hormonal factors can occur at different stages of pregnancy and affect sleep disturbances. The relationship between sleep problems during pregnancy and postpartum depressive symptoms as well as neonatal condition at delivery have not been well described. This study hypothesized that sleep problems are associated with postpartum depressive symptoms and adverse neonatal outcomes at delivery.

Background: Obstructive sleep apnea (OSA) is linked to brain alterations, but the specific regions affected and the causal associations between these changes remain unclear.
Methods: We studied 20 pairs of age-, sex-, BMI-, and education- matched OSA patients and healthy controls using multimodal magnetic resonance imaging (MRI) from August 2019 to February 2020. Additionally, large-scale Mendelian randomization analyses were performed using genome-wide association study (GWAS) data on OSA and 3935 brain imaging-derived phenotypes (IDPs), assessed in up to 33,224 individuals between December 2023 and March 2024, to explore potential genetic causality between OSA and alterations in whole brain structure and function.

Shift work sleep disorder (SWSD) is a circadian rhythm sleep-wake disorders affecting individuals who work in nonstandard hours, particularly night shifts. It manifests as difficulty sleeping during the day and staying awake during work hours, leading to health issues. SWSD is not universally experienced by all shift workers, with about 30% affected.

Advanced sleep phase (ASP) is seldom brought to medical attention because many individuals easily adapt to their early chronotype, especially if it emerges before the age of 30 and is present in a first-degree relative. In this case, the disorder is considered familial (FASP) and is mostly discovered coincidentally in the presence of other sleep disorders, mainly obstructive sleep apnea syndrome (OSAS). The prevalence of FASP is currently estimated to be between 0.

Obstructive sleep apnea syndrome (OSAS) significantly affects the sleep-wake circadian rhythm through intermittent hypoxia and chronic sleep fragmentation. OSAS patients often experience excessive daytime sleepiness, frequent awakenings, and sleep fragmentation, leading to a disrupted circadian rhythm and altered sleep-wake cycle. These disruptions may exacerbate OSAS symptoms and contribute to neurodegenerative processes, particularly through the modulation of clock gene expression such as CLOCK, BMAL1, and PER.
