“…Macro- and trace element deficiencies develop progressively over time, and subclinical manifestations occur long before the onset of clinical deficiency symptoms [ 20 ]. Elemental status depends on age, gender, nutritional status, physical activity level, health status, seasonal changes, and environmental pollution [ 21 , 22 , 23 ]. When assessing the elemental status of those who have recovered from COVID-19, we should remember that an active infection can lead to the loss of macro- and trace elements, such as calcium, zinc, and iron [ 19 ].…”

This study aimed to investigate the content of essential elements in the hair of unvaccinated residents of the Caspian region who recovered from COVID-19. This cross-sectional study involved 260 unvaccinated permanent residents of Mangistau oblast aged 18–60. The diagnosis and severity of COVID-19 were based on clinical signs and symptoms, laboratory data, R-graph results, and oxygen saturation by the Clinical Protocol of the Ministry of Health of the Republic of Kazakhstan. Inductively coupled plasma mass spectrometry determined the content of trace elements cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), iodine (I), manganese (Mn), selenium (Se), and zinc (Zn). The content of Cr (p < 0.05), Cu (p < 0.05), Fe (p < 0.001), I (p < 0.05), Mn (p < 0.001), and Zn (p < 0.05) in the hair of individuals who had a coronavirus infection was lower than those who did not have this infection. There were significantly higher levels of Cu (p < 0.05) in the hair of participants who had moderate or severe COVID-19 compared to those with mild forms. The results of multiple regression analysis showed that in the presence of a COVID-19 infection in a subject’s history, the content of Cr (0.871 (95% CI: 0.811; 0.936)), Cu (0.875 (95% CI: 0.803; 0.955)), Fe (0.745 (95% CI: 0.636; 0.873)), and Mn (0.642 (95%CI: 00.518; 0.795)) decreased in the hair. The data obtained indicate that past COVID-19 infections affect the trace element status of the inhabitants of the Caspian region of Kazakhstan.

“…Uniform reference intervals for children of different ages are incorrect for assessing the metals content in diagnostic biosubstrates. They can lead to the incorrect diagnosis and classification of diseases [ 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. Most studies of metal content in human biosubstrates have covered young children and adults, but the information on adolescents is extremely limited.…”

“…To achieve this, it is advisable to choose an ecologically unfavorable territory, and make a representative sample of children on such a territory according to the values of biological, social, and hygienic criteria [ 6 , 9 , 17 ]. In regional surveys of biosubstrates’ composition, it is necessary to undertake research following uniform experimental conditions [ 16 , 18 , 19 ].…”

Natural and manmade flows of matter form complex metal associations in the body of residents living in certain territories, which leads to functional disorders in their bodies and the depletion of adaptive reserves. It is possible to assess the distribution of metals in the body only taking into account its biogeochemical localization. The question arises about the methodological approach to the determination of regional reference values of the concentrations of metals in biosubstrates of residents of different territories, to which this study was devoted. A designed and trained neural network was used, reflecting the relationship between the concentrations of metals in consumed drinking water and biosubstrates of the body, taking into account the physiological characteristics of the tested group of children and adolescents, based on the regional reference values obtained. Neural network regression methods allowed the calculation of nonlinear dependences of indicators of the state of the internal environment of an organism with external factors, and localized reference values determined in such calculations the indicators of the base state, being guided by the intensity of external factors, which should be assessed. The results of this study are intended for patient-oriented diagnosis and the treatment of eco-conditioned microelementosis in individual locations.

The effects of fast food, instant food and semifinished products on trace element status, hematological and psychological parameters of students were studied. Students who consumed fast food, instant and convenience foods (the 1st group), as well as students who consumed nutrient-enriched health food (the 2 nd group) took part in research (30 participants). Significant decrease in Co, Zn and K content by 1.5, 1.4 and 2.8 times respectively was found in the 1 st group. Also in the 1 st group significant increase in Cu and Na content was determined. Se content in the hair of all participants was lower than normal. The content of toxic elements in all respondents was in the normal range. Lower hemoglobin values were found in students with unbalanced nutrition, but these values did not indicate anemia. For psychological test questionnaire "Well-being, activity, mood" was used. For 27% students with unbalanced diet current psychological state was determined as unfavorable and only for 33%-as favorable. At the same time, the integral indicator of questionnaire "Well-being, activity, mood" positively correlated (r = 0.807, p <0.05) with the hair Zn level.
