Introduction. The novel coronavirus pandemic makes the issue of iron deficiency in pregnancy even more urgent and forces multidisciplinary clinicians to search for modern ways to correct disorders caused by this infection.Objective. To assess the features of the course of post-covid anemia associated with combination therapy, as well as the effect of therapy on the dental health status in pregnant women.Materials and methods. 30 pregnant women (treatment group 1) in the third trimester who had coronavirus infection with mild IDA during gestation were enrolled in the prospective study. Comparison group 2: included 15 patients with mild IDA who did not have coronavirus infection during gestation. Control group 3: included 15 conditionally healthy pregnant women without IDA who did not have a novel coronavirus infection during gestation.Results. Pregnant women who had COVID-19 during gestation were significantly more likely to suffer from gum bleeding, angular cheilitis, oral erosive and ulcerative lesions. Gum bleeding was significantly more common in pregnant women with IDA against the background of coronavirus infection, than in the women in the comparison and control groups (SBI index, p < 0.05). The decrease in the normal microflora suggests the presence of dysbiotic changes in all pregnant women against the background of IDA, however, the patients after the COVID-19 infection had the most significant changes in it.Conclusions. The novel coronavirus infection, which the women had during gestation, aggravates the course of IDA, reduces the quality of life of patients with characteristic complaints (gum bleeding, angular cheilitis, oral erosive and ulcerative lesions), leads to dysbiotic oral microbiome changes. The management of this group of patients requires a systemic correction of the microflora balance, the introduction of individual oral hygiene regimens and adequate treatment of IDA using high-technology medicinal products

Aim. To assess the influence of sex, age and length of service on scientific productivity (h-index in the RSCI, Scopus and Web of Science) of researchers of the National Medical Research Center for Therapy and Preventive Medicine.Material and methods. The study sample was formed from the staff of the National Medical Research Center for Therapy and Preventive Medicine and consisted of scientists of various ranks. The study included 147 people (women, 103; men, 44); Information was collected on their age, education, length of service, academic degree, the position held and author-level metrics  — the h-index, obtained from three abstract and citation databases  — RSCI, Scopus and Web of Science. All study participants were divided into groups by sex and age categories — young (≤39 years), middle-aged (men, 40-60 years; women, 40-55 years) and older (men >60 years old; women >55 years).Results. Analysis showed that 70,1% of the research team consists of women; 60%  — young and middle-aged scientists, and 40%  — older people. Among male researchers, compared with women, there are more doctors of science and high h-index values in the RSCI, Scopus and Web of Science. H-index value in the RSCI among male researchers is 47,3% due to the age and work duration at the National Medical Research Center for Therapy and Preventive Medicine, and among female researchers, 42,8% due to academic degree and length of service. The h-index in Scopus in men is influenced by age, in women  — by the presence of an academic degree, which explain, respectively, 19,7 and 18,1% of its variability. H-index value in the Web of Science in men is associated with the work duration, while in women, with an academic degree and length of service, which explain, respectively, 24,4 and 21,1% of its variance.Conclusion. Women and young and middle-aged scientists prevail in research team pattern of the National Medical Research Center for Therapy and Preventive Medicine. However, male researchers make a more significant contribution to scientific productivity, assessed by the h-index in the RSCI, Scopus and Web of Science. Age and length of service have the greatest influence on scientific productivity for male researchers, while for women — presence of academic degree and length of service. It is necessary to continue research on the study of individual, motivational and institutional factors affecting the scientific productivity.
