The aim: To evaluate the awareness of folic acid, its use and effects, general knowledge about neural tube defects among medical students in Ukraine. Materials and methods: This cross-sectional survey was conducted by questioning 114 fourth and fifth years’ students of the Faculty of Medicine. The questionnaire contained questions about folic acid, its dietary sources, effects and periconceptional uses; spina bifida and its main symptoms. Results: Overall, 96.5% of students knew that folic acid was a vitamin and 95.6% were aware of the one natural product which had a high folate level. However, awareness of its amount in different products was insufficient. Overall, 86.8% of surveyed knew that folic acid deficiency during pregnancy caused the congenital malformations. The knowledge of the synthetic folic acid supplementation before and during pregnancy was low (67.5% and 53.5% respectively). Only 10 % of women among medical students consumed folic acid regularly. Conclusions: Despite the high level of general knowledge about folic acid and its effects among medical students in Ukraine, there is a poor awareness of the pre-conception administration of folic acid, and the number of people who regularly take folic acid among the respondents was very low.

Introduction: Arterial hypertension (HTN) among children is progressively increasing. These concerns have led to an update of the guidelines about childhood hypertension by the European Society of Hypertension (ESH) in 2016 and the American Academy of Pediatrics (AAP) in 2017, and their thresholds for HTN differ. The current research aims to compare the prevalence of hypertension in Ukrainian teenagers using 2 different guidelines and to check the impact of gender, age, and excess weight on hypertension. Material and methods:The sample includes 540 Ukrainian students of 2 secondary urban schools, aged 10-17 years. Blood pressure and anthropometrical measurements were taken and compared with percentile tables. Results: The prevalence of abnormal BP (11.3% and 15.2%) and HTN (1.9% and 4.1%) was determined with ESH and AAP guidelines, respectively, and they strongly depended on which definitions and criteria were used. Boys were much more predisposed to abnormal BP. Comparing both guidelines, there was no significant difference in HTN prevalence in children aged 10-12 years; nevertheless, AAP recognized HTN almost twice as often in teenagers aged ≥ 13 years. Excess body weight was identified in 17.2% of the school-age children, twice as frequently as in males. Conclusions:The results have shown a higher prevalence of HTN in teenagers and children with excessive weight more significant in boys and between children with positive markers of abdominal obesity due to both guidelines, without a significant difference in prevalence after re-classification; however, AAP recommendations might be preferable.

The problem of thyroid dysfunction related to SARS-CoV-2 infection remains unclear in children. Therefore, the study aimed to reveal the interrelationship between thyroid dysfunction and COVID-19 severity­ as well as to determine optimal cut-off values for screening for thyroid disorders in children. A total number of 90 children aged from 1 month to 17 years were involved in the study. Patients with known thyroid disease were not recruited for the research. A thyroid panel was assessed for all participants that included: free triiodothyronine (FT3), free thyroxine (FT4), thyroid-stimulating hormone (TSH) and anti-thyroid peroxidase (ATPO) antibodies. Statistical analysis was done using the computer software Statistica 13.0. Research has revealed euthyroid sick syndrome (ESS) in 14.10% of SARS-CoV-2 infected children more often among patients with severe COVID-19 and multisystem inflammatory syndrome (33.33%) compared to mild COVID-19 course (6.67%) and moderate disease severity (8.89%) (P < 0.05). Significant correlation relationships were revealed for next values – FT3 and erythrocyte sedimentation rate (ESR) (rs = -0.22; P < 0.05); FT3 and C-reactive protein (CRP) (rs = -0.33; P < 0.05); FT3 and procalcitonin (rs = -0.43; P < 0.05). The next cut-off values for ESS determination were revealed: ESR 18.5 mm/h (AUC 0.803); CRP 11.5 mg/l (AUC 0.763); ferritin 84.8 ng/ml (AUC 0.733). Results suggest that pediatricians should pay attention to the endocrine disruptions by COVID-19 in children. Keywords: COVID-19, euthyroid sick syndrome in children, inflammatory markers

Eating disorders are considered to be the cause of obesity, particularly its abdominal type and metabolic syndrome (MS). Until recently, night eating syndrome (NES) and MS were documented only in the adult population, but nowadays they are also seen among children. Therefore, the aim of our study was to determine the association between NES and MS. A total of 120 overweight (18.33%) and obese ( 81.67%) children 10-17 years of age were examined (27 girls (22.5%) and 93 boys (77.5%)). Anthropometric and blood pressure measurements were performed for all children. Serum triglycerides, high-density lipoproteins and glucose levels were assessed. Abdominal obesity was found in 70% of cases. NES was diagnosed in 20.83% of children . MS was found in 34.17% of participants. MS was more prevalent in the NES group (56.00% (95% CI 30.62; 93.96)), compared with the non-NES group (28.42% (95% CI 18.73; 41.35)) (P < 0.05). NES increases the risk of MS development by 3 times ; P = 0.012). Based on these results, careful screening for eating behavior and especially NES should be an integral part of the examination of overweight and obese children with the aim of timely diagnosis of MS. K e y w o r d s: night eating syndrome (NES), metabolic syndrome (MS), children.
