ABSTRACT
Objective. To assess the impact of obesity and overweight on the course of COVID-19. Patients and methods. This prospective study included 218 patients with SARS-CoV-2 infection aged 18 to 94 years hospitalized between June 2020 and March 2021. We evaluated their clinical and laboratory parameters and their association with body weight. All patients were divided into 3 groups depending on their body mass index (BMI). Group 1 included 81 patients with grade 1-3 obesity (BMI >=30);group 2 comprised 71 overweight patients (BMI >=25 and <30);group 3 included 66 patients with normal body weight (BMI >=18.5 and <25). We analyzed clinical symptoms (including shortness of breath, fever, myalgia, headache, fatigue, changes in the oropharynx, cough, rhinorrhea, sore throat, anosmia, and diarrhea), prevalence of concomitant disorders and complications, findings of computed tomography and pulse oximetry, and findings of instrumental and laboratory examinations (complete blood count, urine test, electrocardiography, echo cardiography, biochemical assays, including C-reactive protein, procalcitonin, alanine aminotransferase, aspartate aminotransferase, lactate, lactate dehydrogenase, activated partial thromboplastin time, prothrombin index, D-dimer, ferritin). Data analysis was performed using the Statistica 6.0 software. Results. We found that overweight and obese patients were more likely to have the main COVID-19 symptoms and comorbidities than those with normal weight. Overweight and obese patients also required respiratory support more frequently than patients with normal weight. Obese and overweight patients had more severe systemic inflammation (CRP, procalcitonin), cytolysis (ALT, AST), and thrombosis (D-dimer). Conclusion. Our findings suggest that obesity and overweight are the factors associated with a more severe SARS-CoV-2 infection, which should be considered when planning their treatment and developing resource strategies.Copyright © 2022, Dynasty Publishing House.

ABSTRACT
There is practically no information on the state of oxidative stress reactions in newborns with coronavirus infections. At the same time, such studies are extremely important and can contribute to better understanding of the process of reactivity in patients of different ages. The content of pro- and antioxidant status indicators was assessed in 44 newborns with confirmed COVID-19. It was found that the content of compounds with unsaturated double bonds, primary, secondary, and final LPO products were elevated in newborns with COVID-19. These changes were accompanied by higher SOD activity and retinol level and reduced activity of glutathione peroxidase. Contrary to popular opinion, newborns can be a COVID-19-susceptible age group and require more close monitoring of metabolic reactions during the period of neonatal adaptation that is an aggravating background during infection.

The aim. To assess the general condition, laboratory parameters, quality of life of women of post-reproductive age after asymptomatic COVID-19 and 12 months after moderate COVID-19. Material and methods. We examined 47 women (45-69 years old), divided into 3 groups: those who did not have COVID-19, not vaccinated (group 1- control;n = 15);women 12months after moderate COVID-19, accompanied by pneumonia (group2;n = 19);women with IgG in theirblood who deny anysymptoms of COVID-19 (group 3;n = 13). Results and discussion. An assessment of the general condition of women in postreproductive age was carried out. In women 12 months after COVID-19 we found a lower level of total bilirubin compared to the group with asymptomatic COVID-19 (p = 0.004). An increase in thrombin time was determined in the groups of patients with symptomatic (p = 0.014) and asymptomatic (p = 0.025) COVID-19 course compared with the control group. Patients with asymptomatic COVID-19 course had a higherlevelofhigh-density lipoprotein cholesterolcompared with thecontrolgroup (p = 0.016) and thegroup 2 (p = 0.006). Compared with the controlgroup, the group 2 had lower scores for general health (p = 0.006), vital activity (p = 0.013), general physical well-being (p = 0.039), physical functioning (p = 0.046);and the group 3 had higher scores in role functioning due to physical condition (p = 0.049). When comparing groups 2 and 3, lower scores in the group of women who recovered from the moderate COVID-19 were found in physical functioning (p = 0.002), pain intensity (p = 0.034), role functioning due to physical condition (p = 0.049), general health (p = 0.003), vital activity (p = 0.018), general physical well-being (p = 0.001). Conclusion. 12months after moderate COVID-19, there is a pronounced deterioration inphysicalandemotionalhealth;and in asymptomaticpatients, betterprotective functions of an organism can be assumed. © 2022 Acta Biomedica Scientifica.

ABSTRACT
Background: during the COVID-19 pandemic, many mental health problems among the population have been exacerbated, which raised fears regarding possible increase in suicides. In response to that, studies of suicidal behavior all around the world have grown substantially. In many countries, given the constantly changing situation, research is based not only on national statistical data, which are usually 1–1.5 years late, but efforts are made to collect real-time information. The aim: to integrate the results of observations regarding possible associations between suicidal behavior and pandemic waves and restrictive measures and offer explanations for the observed trends. Materials: relevant papers were identified during the monitoring of domestic and foreign scientific databases. Results: observations show that after the announcement of severe restrictive measures, despite the fact that the level of stress, anxiety, depression, addictions and other mental health disorders increased in the population, there was no increase in suicide mortality. On the contrary, in many countries, cities and regions, more frequently decrease in completed suicides, as well as in non-fatal suicidal behavior, was observed. The explanation of this phenomenon is related to the concept of crisis and lies in the field of sociological theories to a greater extent than in the field of the medical and psychiatric model of suicide. A pandemic is a typical example of a global crisis, which is characterized by an acute, chronic and recovery phase. After the crisis will be over and in the longer perspective, due to the anticipated serious changes in the lives of large contingents of people, it is necessary to be prepared for possible negative tendencies in suicidal behavior. Conclusion: despite the fact that the current pandemic did not result in an increase of suicides, it is necessary to intensify research in the field of suicidology. Efforts aimed at developing, organizing and implementing more effective suicide prevention measures are needed. It is essential that they should be culturally and organizationally acceptable and adapted to the current level of intensity of information flows. © 2022, Psychiatry (Moscow).All Rights Reserved.
ABSTRACT
The aim of our research was to assess the intensity of oxidative stress (OS) in children and adolescents with COVID-19 using the oxidative stress index (OSI). Methods and Results: The study was conducted between May 2020 and March 2021. The main group included 17 children and adolescents [8(47.1%) boys and 9(52.9%) girls;mean age of 12.35-14.01 years] with diagnosed COVID-19 infection (mild to moderate course) selected as a result of the primary diagnostic examination from among those admitted to hospitalization at the Irkutsk Regional Infectious Diseases Clinical Hospital. The control group included 17 healthy children and adolescents (average age of 12.35-14.01 years) matched by copy-pair type. The obtained data indicated statistically significant differences in a number of parameters between children and adolescents with COVID-19 and the contiol groups. We found statistically significant higher levels of lipid peroxidation (LPO) products (CDs, P<0.0001;KD and CT, P=0.006;and TBARs, (P=.013) in the study group than in the control group. Among antioxidant defense (AOD) system parameters, the levels of retinol (P=0.015) and reduced glutathione (P=0.048) and SOD activity (P<0.0001) were statistically lower in the study group than in the control group. The OSI level was significantly greater (by 8.5 times, P=0.028) in the study group than in the control group, which confirms the development of antioxidant deficiency in COVID-19. Conclusion: The results of the assessment of OSI in children and adolescents with COVID-19 indicate insufficient activity of some critical components of AOD and a shift of the redox balance toward pro-oxidant factors, which can have extremely negative consequences in the development of the disease. In this regard, we recommend carrying out corrective measures to stabilize LPO/AOD parameters by including drugs with antioxidant properties in the treatment complex.
ABSTRACT
The study involved 271 patients (132 men and 139 women) with moderate COVID-19. Superoxide dismutase (SOD) activity in erythrocytes was measured spectrophotometrically. In total group of patients (divided into age groups of 18-35, 36-45, 46-60, and 61-90 years), higher SOD activity was found in the 18-35 age group in comparison with the groups 46-60 years (p<0.01) and 61-90 years (p<0.05). Then, the groups were additionally divided by sex. In men, no differences in enzyme activity were found between the age groups. In women of early reproductive age, SOD activity was higher than in groups 36-45, 46-60, and 61-90 years. The sex differences consisted in higher SOD activity in women aged 18-35 years in comparison with men of this age. These data should be taken into account when choosing the tactics of therapy for patients with moderate COVID-19 course.

Background. The COVID-19 pandemic has raised the importance of this problem to the first stage and has affected healthcare system around the world. Despite the more favorable COVID-19 course, the child population should be at focus of special attention, due to the active participation in its distribution. The course of COVI D-19 includes a cascade of pathological processes accompanied by the generation of reactive oxygen species, which can have extremely negative consequences for the developing organism. The research of these processes in children is vital and will improve the effectiveness of preventive and therapeutic measures. The aim: to analyze changes in enzymatic and non-enzymatic links in the antioxidant defense in children and adolescents with diagnosed COVID-19 infection. Materials and methods. 17 children and adolescents (average age - 12.35 ± 4.01 years) were examined, including 8 boys (47 %) and 9 girls (53 %) with COVID-19 infection. The control group of children and adolescents (practically healthy) according to the «copy-pair» principle was selected. We used spectrophotometric methods. Results. In the group of children and adolescents with diagnosed COVID-19 infection, there were lower levels of total antioxidant activity (p < 0.0001), superoxide dismutase activity (p < 0.0001), content of reduced glutathione (p = 0.048) and retinol (p = 0.015), increase in glutathione reductase activity (p = 0.015) relative to the control. Conclusion. The obtained data indicate the insufficiency of antioxidant system components number in children and adolescents with diagnosed COVID-19 infection and indicate the advisability of antioxidant therapy using to stabilize these indicators. © Acta Biomedica Scientifica 2021.
ABSTRACT
There are observations that right after total quarantine measures were introduced, there was no growth in number of suicides, but a situation remains unclear when it comes down to new waves in the pandemic development. Our research goal was to estimate risks of suicide in heterogeneous population groups in 2020, that is, from the pandemic start and up to the second wave rise. We analyzed data on completed suicides in Saint Petersburg, Udmurtia Republic (Russia), and Odessa region (Ukraine), 6375 cases overall among population groups with total number of people being equal to 9,216 thousand starting from January 01, 2016 to December 31, 2020. Confidence intervals for frequencies as per months (per 100,000 people) in 2020 were calculated as per Wilson and compared with average ones calculated for 2016–2019. There was a decrease in frequency of completed suicides in all three population groups during a period when the strictest quarantine measures were valid;by the mid-summer the trend normalized or there was even a slight increase. When the second pandemic wave came, changes were multidirectional;in particular, in Saint Petersburg there was another decrease by the end of the year, the most apparent and statistically significant among men whereas there were short-term rises in Udmurtia and Odessa. Our comparison performed for population groups with initially different levels of suicides confirms that right after a crisis starts, suicidal behavior becomes less frequent among people;however, as a response to the second pandemic wave, we can expect both falls and rises in number of suicides and it requires more intense preventive activities. © Rozanov V.A., Semenova N.V., Kamenshchikov Yu.G., Vuks A.Ya., Freize V.V., Malyshko L.V., Zakharov S.E., Kamenshchikov A.Yu., Isakov V.D., Krivda G.F., Yagmurov O.D., Neznanov N.G., 2021
