Coping Strategies During the COVID-19 Pandemic and Self-Determination: A Review of Russian Studies.

Background: The COVID-19 pandemic is a multifaceted stressor. Its impact suggests long-term psychological effects. Self-determination promotes flexibility of goals and actions and helps to overcome the difficulties caused by stress. Objective: To analyze coping strategies during the COVID-19 pandemic presented in Russian scientific studies (RQ1), and their relationship with self-determination (RQ2). Design: Relevant studies (2020-2022) were selected from the Russian citation index (RSCI) database. Strict selection criteria were used. Twenty-four articles were selected for the final review. For dynamic analysis, four stages of the pandemic were identified. Results: Prevailing coping strategies have changed over time. At the beginning of the pandemic, respondents used familiar coping mechanisms. Six months later, active coping strategies were more often used, but deprivation and avoidance strategies increased. A year later, there was an increase in denial and avoidance strategies. Using non-constructive coping strategies may indicate that, due to the long course of the pandemic, meeting basic psychological needs became increasingly frustrated, leading to helplessness, alienation, and lack of control. Later dynamics reflect the growth of effective coping strategies and confirm that when basic needs are blocked for a long time, people seek alternative ways to satisfy them. Conclusion: The dynamics of coping strategies during the pandemic reflected their close relationship with basic psychological needs, as described in the theory of self-determination. The results confirmed the importance of self-determination as a dispositional variable in predicting coping mechanisms.

[The confidence limits of self-education of medical workers in matters of competences to provide quality and safety].

The article considers possible risks according analysis of comprehension by workers of necessary competencies ensuring quality and safety of medical activities at performing their duties as well as assessment of factors affecting completeness of choice. It is proposed to apply corporate training as component targeted to improving quality and safety of medical activities by addressed training of necessary competencies within the framework of continuous medical education, supplementing existing self-education.

[Predictive value of QRS complex duration in patients with chronic heart failure and atrial fibrillation: retrospective study].

AIM: To study of the features of the clinical course and prognosis in patients with chronic heart failure with low ejection fraction (HFrEF) and atrial fibrillation (AF) depending on the width of the QRS complex. MATERIALS AND METHODS: We studied the case histories of 514 patients (aged 60.213.84 years, 78% men) with HFrEF, hospitalized at the Chazov National Medical Research Center of Cardiology (Moscow) for the period from Jan 1, 2017 to Dec 31, 2018. Patients were divided into 2 groups depending on the duration of the QRS complex. RESULTS: Clinical and statistical retrospective analysis of the medical histories of patients with HFrEF, depending on the QRS duration, showed the predominance of patients with a QRS complex size of less than 130 ms (60.7%). In HFrEF, the expansion of the QRS complex is accompanied by an increase in the rate of readmission in patients with sinus rhythm (p=0.004). In patients with AF, the rehospitalization rate is significantly higher than in sinus rhythm and does not depend on the QRS duration (p=0.001). The incidence of unfavorable outcomes increases in connection with the addition of AF, which is most likely a more significant risk factor than QRS width. CONCLUSION: These results highlight that patients with AF and a narrow QRS complex have the same poor prognosis as those with a wide QRS complex and require the close attention of cardiologists.
