    Background. Evaluating and monitoring plasma levels of anti-SARS-CoV-2 antibodies in healthcare workers, together with the vaccination of this at-risk population is important for maintaining the viability of the healthcare system, especially during the emergence of new viral variants. The aim of this study is to investigate plasma levels of anti-SARS-CoV-2 antibodies in healthcare providers following full vaccination, in both naïve and previously infected individuals. Material and methods. Complete data was available for 89 healthcare workers from the larger group of 102 initial participants. Plasma was collected at least one month, and no later than two months after the full dose of an mRNA vaccine, and analyzed by determining the total antibody concentration against the spike protein using an ECLIA kit. Results. The degree of humoral-specific immune response was at least 5-fold higher in previously infected healthcare workers compared to naïve persons that received the vaccine only. The highest titer was found in office-based staff, relative to those found in doctors and nurses. However, this difference lacks statistical significance. Among previously infected participants, nurses had significantly higher antibody titers, when compared to doctors. Conclusions. The study revealed a sustained immune response after mRNA vaccine among healthcare workers, with enhanced response in previously infected subjects, highlighting a boosting effect of the vaccine.

    COVID-19 monitoring and tracking system using information technologies and artificial intelligence
    (Akademia Bialska Nauk Stosowanych im. Jana Pawła II, 2021-08-20) Vikhrov, Igor ; Ashirbaev, Sherzod
    The appearance of COVID-19 almost coincided with the beginning of an active phase of the digitalization process in all areas, including public health. Moreover, COVID-19 unwittingly became an impulse that accelerated the introduction of digital technologies, as well as initiated new innovative solutions to combat both the virus and its devastating social and economic consequences. At the time of writing this letter to the Editor, COVID-19 is still actively spreading, having a negative impact on the global economy and health, despite the start of global vaccination. In this regard, the governments of all countries are developing new innovative approaches to prevention, treatment and rehabilitation of the virus.

    The selection of stress coping strategies by university students based on prior COVID-19 exposure

    Background. The present study examined factors influencing the choice of coping strategies in response to stress caused by the pandemic. The aim of the study was the analysis of the selection of coping strategies chosen by university students stratified based on whether they had previously contracted coronavirus disease (COVID-19). Material and methods. A variant of the COPE questionnaire was used to examine the choice of coping strategies among 876 students of Krasnoyarsk (Russia) during the lockdown. Fifteen coping strategies were assessed in 27.9% students who had COVID-19 and 72.1% who did not have COVID-19, taking into account sex differences. Results. Problem-oriented and active coping strategies were common in both groups. The most common scenarios are active handling strategies (median 6.0). In both groups, respondents rarely singled out (median ≤4.0) the use of psychoactive substances, denial of the situation, and conversion to religion. Females more often than young males used concentration on emotions as a coping strategy. Females who experienced COVID-19 refuse to believe what happened, and choose to seek social support for emotional reasons. Conclusions. The risk of infection and the transmitted illness engendered coping strategies associated with active actions. Passive coping strategies were used less frequently. The tactics used to select appropriate coping strategies for those who have not been ill and who have recovered are similar, irrespective of sex.
