Current incidence of professional burnout among ukrainian oncologists in Kharkiv
(International Journal of Occupational Medicine and Environmental Health, 2023) Böckelmann, Irina; Zavgorodnii, Igor; Litovchenko, Olena; Kapustnyk, Valeriy; Krasnoselskyi, Mykola; Zub, Kseniia; Woitha, Ulrike; Gonschor, Cecile; Thielmann, Beatrice
Objectives: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic and the military conflicts in Ukraine suggest that workrelated stressors increased during these crises increases work-related stress reactions. Burnout as a long-term consequence of insufficiently compensated for workloads. The egional prevalence of burnout is particularly high among oncologists. The aim of this study was to assess the current risk of burnout within this group of physicians and to examine gender differences through gender-based analysis. Material and Methods: Thirtyseven oncologists (17 men and 20 women aged 46.5±13.6 years [range 26–74 years]) in Kharkiv, Ukraine, participated. The Maslach Burnout Inventory – General Survey (MBI-GS) questionnaire was used to determine the extent of occupational. Results: Gender, age, and work experience had no effect on the following results. Women demonstrated higher scores in emotional exhaustion and personal accomplishment of the MBI than men. In contrast, men offered higher cynicism scores. The MBI total score was also higher for the male oncologists. Only 1 person of the total sample had risk of burnout. Conclusions: The results showed a high prevalence of burnout symptoms among Ukrainian oncologists without gender differences. From occupational health perspective behavioral and behavior-preventive measures are needed for clinics and oncologists to counteract the Burnout symptoms, e.g. exhaustion or cyniscism. Further studies are needed here to examine the effectiveness of these measures.
Current standards for the ergonomics design of software for visual digital assistance systems in Germany
(International Journal of Occupational Medicine and Environmental Health, 2023) Böckelmann, Irina; van Schelve, Jonas; Zavgorodnii, Igor; Minow, Annemarie
The aim of the research – considering the industrial changes in times of Work 4.0, new digital solutions must be implemented. The systematic overview of the existing standards should contribute to the human-centred design of assistive systems and provide support for the development and evaluation of new digital assistance systems. Materials and methods of the research. Within the framework of the joint project «3D-Montageassistent» funded by BMBF), various databases were searched for standards and guidelines for the ergonomic design of digital assistance systems existing in the national and international area. Results. With regard to the objectives, the standards series DIN EN ISO 9241 «Ergonomics of human-system interaction» as well as DIN EN ISO 26800 «Ergonomics – General approach, principles and concepts» and DIN EN ISO 6385 «Ergonomics principles in the design of work systems» stand out in particular. Conclusions. A multi-professional cooperation forms the current path of occupational medicine. The individual is placed at the centre of attention for the design and is promoted preventively. Some standards already exist for the human-centred design of digital assistance systems, but the development of new legislation cannot keep pace with the speed of development of new technologies. For the harmless use of visual digital assistance systems, the deficits must be addressed.
Heart rate variability as a strain indicator for psychological stress in emergency medical services personnel during working days: a systematic review
(International Journal of Occupational Medicine and Environmental Health, 2023) Thielmann, Beatrice; Voß, Linda; Zavgorodnii, Igor; Schumann, Heiko; Böckelmann, Irina
Introduction. Emergency medical services personnel have highly variable workloads. The resulting stress can differ intra- or inter-individually. Consequences for health arise when there is insufficient compensation for prolonged stress. The analysis of heart rate variability (HRV) is a valid noninvasive method for the objective monitoring of workload in the occupational medicine. The aim of the research is to systematically evaluate the literature on HRV as an objective indicator of the mental stress faced by emergency medical services рersonnel. Materials and methods of the research. A systematic literature review examining the HRV of prehospital emergency medical services personnel in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement for reporting systematic reviews was performed. PubMed, Ovid, Cochrane Library, Scopus, and Web of Science electronic databases were used. Modified STARD for HRV was used to evaluate the methodological quality of HRV measurement. Two authors independently reviewed the papers and performed the evaluations. Results. The literature search identified 5,637 citations. Four studies were included that investigated HRV during working days compared to nonworking days, but no focus on alert operations. Two studies used Holter electrocardiographic, and two used chest belts. Two studies evaluated cardiac autonomic function in the time and frequency domains, and the other two studies used only the time domain. The results showed an adaptation of HRV under working conditions. The studies were not comparable, because the study protocols were different. Conclusions. There is a need for аccupational health studies that examine the strains and stress of emergency medical services personnel, especially under alert interventions. The well-established HRV parameters seem to be suitable for objectively measuring stress. HRV measurement is also suitable for active alert and operation around the patient. Future research should further additionally investigate nonlinear parameters or parameters without clear assignment. Guideline standards should be respected.
Influence of low-frequency electromagnetic radiation on the complement system (experimental study)
(Львівський національний медичний університет імені Данила галицького, 2023) Zavgorodnii, Igor; Litovchenko, Olena; Merkulova, Tetiana; Chekhovska, Iryna; Sushchenko, Elina; Shenher, Anastasia
t. The article presents the data of an experimental study on determining the state of the complement system under the conditions of exposure to low-frequency electromagnetic radiation (EMR) on the body of rats under the conditions of a subacute experiment. The relevance of the research is dictated by the fact that low-requency EMR can change the membrane potential and disrupt nerve cell conduction. This can primarily affect the functioning of the hypothalamic-pituitary adrenal system, which also influences the effectiveness of the immune system functioning. In the conditions of the natural experiment, male rats were exposed to radiation of 600 V/m with a frequency of 70 kHz for 4 hours every day for 30 days. The studies of immunological indices were carried out in the dynamics of the experiment on the 5th, 15th and 30th days. The study showed that under conditions of 30-day exposure to low-frequency EMR, the humoral link of immunity was characterized by suppression of the C4 component in the first half of the study, followed by a compensatory increase in the C4, C5 components. It has been proven that the general effector reactions of activation of the complement system are able to influence the functions of lymphocytes and macrophages. Thus, under the conditions of an anthropogenic factor, a flexible adaptation process takes place in the body of rats, which involves the redistribution of protein functions for the purpose of "economic" functioning of the body under the conditions of stressor action.
