Material and Methods — This research was an observational cross-sectional study based on data extracted from 47,113 electronic medical records (EMRs) of patients 20-99 years of age residing in Tambov. The study included 29,282 (62.2%) women and 17831 (37.8%) men. Results — Essential hypertension is habitually associated with osteochondrosis (41.5% of patients with hypertension), cerebrovascular diseases (35.1%), arthrosis (28.3%), ischemic heart disease (IHD) (28.7%), menopausal disorders (17.5%), pancreatic diseases (15.4%), diabetes mellitus (14.7%), benign mammary dysplasia (14.2%), retinal diseases (12.9%), disorders of lipoprotein metabolism (12.4%), senile cataract (10.6%), gastritis and duodenitis (10.7%), varicose veins (10.1%), and thyroid diseases (10.0%). IHD is more common among men with hypertension, while other comorbidities are more characteristic for women. The most striking gender-related difference was associated with the finding that women with hypertension had varicose veins as a comorbidity (RR=1.398; 95% CI 1.376-1.422), while the smallest difference between genders related to retinal diseases (RR=1.065; 95% CI 1.038-1.092). IHD was strongly associated with the male gender (RR=1.101; 95% CI 1.056-1.148). Three diseases were more often associated with hypertension in the age range of 80-89 years (cerebrovascular disease, IHD, osteochondrosis); some of the diseases had the highest incidence in the age range of 60-69 years, and other disorders occurred in the age range of 40-59 years. Conclusion — The gender- and age-related features of comorbid pathology associated with essential hypertension among urban residents revealed in this study are extremely important in the clinical practice of a local general practitioner for developing optimal patient-oriented treatment plans.","PeriodicalId":21426,"journal":{"name":"Russian Open Medical Journal","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43569557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, only 88 of these publications complied with the objective of the review. We included 75 full-text publications in this review. Results — Physicians and nurses during COVID-19 pandemic do not have the opportunity to take therapy aimed at combating the symptoms of sleep disorders, due to the need to maintain sufficient attention and the risk of developing excessive drowsiness while on duty in a COVID -19 hospital. The latter can have a negative impact on their professional activities. Thus, this problem certainly requires professional psychotherapeutic correction. Unfortunately, not all medical institutions have such specialists. Conclusion — Based on the literature review, we found out that health care workers have a high risk of developing sleep disorders. This can include violations of the circadian rhythm, a decrease in the quality and duration of night sleep, daytime hypersomnia caused by shift work in a hospital. An additional factor affecting the frequency and severity of sleep disorders in healthcare workers (physicians and nurses) is chronic stress, the importance of which has increased during the COVID-19 pandemic. Currently, the above problem has not been completely solved and requires research in this area and the development of new programs to help medical personnel.","PeriodicalId":21426,"journal":{"name":"Russian Open Medical Journal","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44845393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Material and Methods — The study involved 10 healthy men 27 to 35 years of age. Reciprocal and presynaptic inhibition was evaluated by suppressing the amplitude of testing H-reflex of m. soleus under conditions of conditioning stimulation of n. peroneus profundus and testing stimulation of n. tibialis with interstimulus intervals of 3 ms and 100 ms, respectively. Reciprocal inhibition and presynaptic inhibition were recorded during a 20-minute tESCS in the area of T11-T12 thoracic vertebrae at rest, in combination with voluntary muscular effort (5% of the maximum voluntary contraction), and after the stimulation. Results — During 20-minute electrical stimulation of the spinal cord at rest, the severity of reciprocal inhibition decreased, inverting to reciprocal facilitation, while presynaptic inhibition weakened only at the twentieth minute of stimulation; and in the postactivation period, the activity of spinal inhibition processes in the antagonist muscle system corresponded to background values. The most pronounced effect of prolonged tESCS was observed when performing a weak isometric contraction, which was accompanied by an increase in reciprocal inhibition activity during 10 minutes of exposure and 10 minutes after the end of stimulation. The severity of presynaptic inhibition during and after the spinal cord stimulation remained unchanged and complied with background values. The presynaptic inhibition activity was expressed to a greater extent during prolonged stimulation of the spinal cord at rest, and when performing a weak voluntary effort, as well as during the postactivation period. Conclusion — Changes in the spinal inhibitory interactions in the system of antagonist muscles on the basis of tESCS effects during arbitrary muscle tension could probably be explained by the fact that in this case, the inhibitory interneuron circuits of spinal cord were exposed to a wider range supraspinally descending and ascending peripheral effects, compared with spinal cord stimulation in a state of a relative muscle rest.","PeriodicalId":21426,"journal":{"name":"Russian Open Medical Journal","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44254144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The activity of retroelements in the brain is impaired under the influence of SARS-CoV-2, penetrating the blood-brain barrier. We propose a new concept, according to which the neurological complications of COVID-19 and their long-term effects are caused by modified expression of retroelements in neurons due to viral effect. This effect is implemented in several ways: a direct effect of the virus on the promoter regions of retroelement-encoding genes, virus interaction with miRNAs causing silencing of transposons, and an effect of the viral RNA on the products of retroelement transcription. Aging-related physiological activation of retroelements in the elderly is responsible for more severe course of COVID-19. The associations of multiple sclerosis, Parkinson’s disease, Guillain-Barré syndrome, acute disseminated encephalomyelitis with coronavirus lesions also indicate the role of retroelements in such complications, because retroelements are involved in the mechanisms of the development of these diseases. According to meta-analyses, COVID-19-caused neurological complications ranged 36.4-73%. The neuropsychiatric consequences of COVID-19 are observed in patients over a long period after recovery, and their prevalence may exceed those during the acute phase of the disease. Even 12 months after recovery, unmotivated fatigue, headache, mental disorders, and neurocognitive impairment were observed in 82%, 60%, 26.2-45%, and 16.2-46.8% of patients, correspondingly. These manifestations are explained by the role of retroelements in the integration of SARS-CoV-2 into the human genome using their reverse transcriptase and endonuclease, which results in a long-term viral persistence. The research on the role of specific retroelements in these changes can become the basis for developing targeted therapy for neurological consequences of COVID-19 using miRNAs, since epigenetic changes in the functioning of the genome in neurons, affected by transposons, are reversible.","PeriodicalId":21426,"journal":{"name":"Russian Open Medical Journal","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47714819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All patients were evaluated by a lipidogram, adipokine, glycemic profiles, and ultrasound examination of the heart and carotid arteries. Results — Criteria for metabolically neutral abdominal obesity in men were determined: weight gain >30 kg/m2 in the presence of no more than two criteria for metabolic syndrome and leptin level <3.5 ng/ml. The metabolically neutral type was characterized by a better lipid profile, which was confirmed by a lower frequency of dyslipidemia (1.7 times); the frequency of prediabetes was 7% and was half as low as in metabolically healthy obesity; atherosclerosis of the carotid arteries was 1.5 times less common in the neutral type of obesity. Conclusion — The selection of a \"metabolically neutral\" type of obesity is justified since it allows us to determine the stage of the disease at which the frequency of metabolic and cardiovascular disorders is still minimal and non-drug prevention is necessary.","PeriodicalId":21426,"journal":{"name":"Russian Open Medical Journal","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42787353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
