Objective: To develop an effective diagnostic algorithm for detection of a mental component in the state of patients diagnosed with autonomic nervous system disorder.
Material And Methods: In the frames of START1 epidemiological study, we examined 6633 patients with autonomic nervous system disorders (ICD-10 G.90.8 and G90.9) and somatoform disorders (F45) including 18,8% patients who got a referral to a psychiatrist. A linguistically validated Russian version of The Dutch Four-Dimensional Symptoms Questionnaire (4DSQ) was tested in domain subpopulations.
Results: In subpopulations of anxiety and depression, more than 26% of the patients got a referral to a psychiatrist that indirectly supported the assumption on the conformity of 4DSQ to the purposes of primary screening of four-dimensional disorders in the general population of patients with autonomic nervous system disorders.
Conclusion: The linguistically validated Russian version of 4DSQ enabled to formalize the description of clinical profile of these patients. Cluster analysis of the results allowed to single out two superdomains by the pairwise combination somatization with distress (SDis) and anxiety with depression (ADep). The detection of superdomain SDis appears to be a population specific characteristic of autonomic nervous system disorders in the Russian Federation.

Purpose Pre-clinical studies have demonstrated direct influences of the autonomic nervous system (ANS) on the immune system. However, it remains unknown if connections between the peripheral ANS and immune system exist in humans and contribute to the development of chronic inflammatory disease. This study had three aims: 1.

Background: Microwave ablation is a new, minimally invasive technique for the treatment of thyroid nodules. Hyperthyroidism due to destructive thyroiditis is a known risk of microwave ablation, though it occurs in only a minority of cases. We report a rare case of a patient diagnosed with Graves' disease nearly six months after undergoing microwave ablation of a thyroid nodule.

Purpose: This study explores the use of heart rate variability (HRV) analysis, a noninvasive technique for assessing the autonomic nervous system, by applying nonlinear dynamics and chaos theory to detect chaotic behavior in RR intervals and assess cardiovascular health.
Methods: Employing the "System Analysis of Heart Rate Dynamics" (SADR) program, this research combines chaos analysis with the short-time Fourier transform to assess nonlinear dynamic parameters in HRV. It includes constructing phase portraits in Takens space and calculating measures of chaos to identify deterministic chaos indicators.

Temporomandibular joint osteoarthritis (TMJ-OA) is a common disease often accompanied by pain, seriously affecting physical and mental health of patients. Abnormal innervation at the osteochondral junction has been considered as a predominant origin of arthralgia, while the specific mechanism mediating pain remains unclear. To investigate the underlying mechanism of TMJ-OA pain, an abnormal joint loading model was used to induce TMJ-OA pain.

Although often overlooked sleep apnea has emerged as a significant public health concern. Obstructive sleep apnea (OSA) and diabetes commonly co-exist with a vicious cycle worsening the incidence and severity of both conditions. OSA has many implications including cardiometabolic disorders and impaired cardiovascular (CV) prognosis.
