Objectives: Sleep apnea syndrome affects approximately 4% of adult males and 2% of adult females. It is associated with significant cardio-, cerebrovascular, metabolic and hormonal comorbidities and ranks among the more expensive medical specialties due to the requirement of high-quality technical diagnostic and therapeutic equipment as well as well-educated and experienced personnel. The aim of this study is to detect the relationship between C-reactive protein (CRP), pentraxin-3 (PTX-3), interleukin 6 (IL6), high-sensitivity troponin I (hsTnI), brain natriuretic protein (BNP) and galectin-3 serum levels and obstru-ctive sleep apnea syndrome.
Design: Prospective cohort study.
Material And Methods: A group of 146 patients with middle to severe obstructive sleep apnea syndrome (OSAS) were monitored, and the results were compared with the results from a control group of healthy individuals.
Results: We assessed serum levels of the following biomarkers: CRP, PTX-3, IL6, hsTnI, BNP, and galectin-3. PTX-3 serum levels were statistically significantly higher (p<0.0001) in patients with OSAS, compared to controls. Statistical results related to the other biomarkers did not suggest any clinical value. ROC analysis showed that PTX-3 might be able to distinguish patients with OSAS from healthy individuals (AUC=7438).
Conclusion: The elevation of PTX-3 serum levels is significantly associated with middle to severe obstructive sleep apnea syndrome. The PTX-3 biomarker appears to be a promising alternative method for sleep apnea syndrome investigations.

Background: Sleep apnea syndrome (SAS) is associated with hypertension and vascular remodeling. Hypoxia-inducible factor-1α (HIF-1α) and the Hippo-YAP pathway are implicated in these processes, but their specific roles remain unclear. This study investigated the HIF-1α/Hippo-YAP pathway in SAS-related hypertension.

Objective: To analyze the results of nocturnal breathing parameters during sleep based on nocturnal pulse oximetry and to study of characteristics of external respiration in genetically confirmed patients with dystrophic myotonia (DM).
Material And Methods: The subjects of the study were patients with genetically confirmed DM types 1 and 2 who were hospitalized in the neurological departments of the Republican Scientific and Practical Center for Neurology and Neurosurgery. The clinical picture of the disease, comorbidities, sleep questionnaires, laboratory tests, overnight pulse oximetry and spirometry were performed and analyzed.

Background: Dizziness and unstable gait with resultant falls are common symptoms among the older adults. Most of studies have focused on statistical analysis regarding single factor related to dizziness and unstable gait. On the other hand, there are very few comprehensive studies using a large number of patients except several review papers.

Background: Obstructive sleep apnea (OSA) is an often overlooked, widespread disease and a public health concern. Evidence-based practice guidelines do not exist to guide primary care clinicians' OSA screening practices. Clinicians must be competent in OSA; however, clinicians lack competency about this disease.

Introduction: Moderate-to-severe obstructive sleep apnea (OSA) affects a large segment of the US population and is characterized by repetitive and reversible obstruction of the upper airway during sleep. Untreated OSA is associated with increased incidence of heart attack, stroke, and motor vehicle accidents due to sleepiness. Continuous positive airway pressure is often prescribed, but most patients with OSA are nonadherent.
