Objective. To assess age and sex differences in sleep disorders as risk factors and markers of hypertension (HTN) in 18–39-year old people with normal body weight. Design and methods. We performed a cross-sectional study based on the internet survey of 18–39-year-old people with body mass index of 18–25 kg/m2  (n = 2094). The unvalidated questionnaire included 42 questions about various types of sleep disorders and sleep-associated symptoms (0 — never, 1 — rarely, 2 — from time to time, 3 — quite often, 4 — almost all the time). Results. The probability of detecting HTN in young men with normal body weight is higher than in women with similar characteristics (p < 0,001). In women, the probability of detecting HTN decreases, starting with the youngest category (18–24 years old), reaching a minimum in the age group 30–34 years old and then starts to increase. By the age of 40, the indicators for men and women become similar. Based on a multivariate analysis, the risk of HTN in young people with normal body weight is associated with both gender and age (p = 0,022). The contribution of gender to age-related changes in sleep complaints was found for snoring (p < 0,001), sleep apnea (p < 0,001), early awakenings (p = 0,002). The contribution of gender was also noted for various symptoms — daytime sleepiness, some symptoms of restless legs syndrome (RLS), anxiety, depression, leg cramps (p < 0,001) and nocturnal heartburn (p < 0,001). The contribution of age was noted for snoring (p < 0,001), sleep apnea (p < 0,001), early awakenings (p < 0,001) and for a variety of symptoms — daytime sleepiness, some symptoms of RLS, anxiety, nocturnal cough, and nocturnal choking. Conclusions. Our data can be considered when developing measures for HTN prevention, can be recommended for clinical use, as well as in subsequent clinical studies using validated questionnaires.

Background. Vitamin D affects the function of many organs and systems. Lipid metabolism disorder is established to be one of the risk factors for vitamin D deficiency, and the amount of adipose tissue is crucial. Objective. The aim of the study was to determine the prevalence and risk factors for vitamin D deficiency in overweight and obese adolescents. Methods. 146 children with excessive weight and obesity as well as 63 healthy children with normal body weight were examined. In the study groups, there were no children taking vitamin D. Vitamin D status was evaluated by the level of 25(OH)D in blood serum. Vitamin D deficiency was diagnosed at the level of 25(OH)D between 20 and 29 ng/ml, and significant deficiency – below 20 ng/ml, normal calcidiol content was 30-100 ng/ml. Results. The average level of 25(OH)D in the adolescents with normal body weight was 19.76±4.28 ng/ml, in the adolescents with excessive body weight – 15.24±3.47 ng/ml, and in the obese children – 13.87±2.71 ng/ml. The prevalence of vitamin D deficiency in the overweight adolescents was 70.62%, and in the adolescents with obesity – 77.19%. Conclusions. Vitamin D deficiency is prevalent in the adolescents with overweight and obesity. To prevent the development of hypovitaminosis and vitamin D deficiency, it is necessary to carry out educational activities with adolescents for promotion of healthy lifestyle and healthy food, as well as to develop an optimal program for improving vitamin D status in the obese children.

Aim. To study features of heart rate of men with arterial hypertension and obesity, to identify factors associated with arrhythmia evolution.Materials and methods. The study included 3 groups of men (with obesity – 98 men, with excessive body weight – 46 men, with normal body weight – 40 men). The comparative analysis of heart rhythm was performed with Resting ECG and Holter ECG monitoring, blood pressure from daily monitoring, echocardiography, blood lipid spectrum, glycaemia. The adiponectin level was analyzed only for group with obesity.Results. Obesity in men with arterial hypertension increases the frequency of arrhythmias of atrial fibrillation (AF) type (15.3% vs. 0% in group with normal body weight, p=0.004) and increases the frequency of ventricular premature beats (VPB) (26.5% in group with obesity vs. 10% in group with normal body weight). We were also able to show the relation between arrhythmia and the severity of obesity. Obesity with arterial hypertension significantly increases the risk of various arrhythmias (more than 6 times for AF risk – p=0.004 and more than 5.31 times for frequent VPB – p=0.026. Risk factors for AF are statistically significant with the presence of obesity: left ventricular (LV) and left atrium (LA) dilation, II–III stage of hypertension and low level of high-density lipoprotein (p0.05). AF risk factors are significant without relation to obesity: left ventricular hypertrophy, dilatation LA, IHD (p0.05). But there is no relation between ischemic heart disease (IHD) and an increased risk of AF evolution. Also no relation was found between sleep apnea syndrome and arrhythmias.Conclusion. Men with excessive body weight or obesity in contrast to men with normal body weight have an increased risk of AF and VPB. Factors directly associated with arrhythmias: heart remodeling (hypertrophy and dilatation of the left ventricular, dilatation of the left atrium), advanced stages of arterial hypertension, dyslipidemia; IHD with obesity associated with risk of VPB and doesn’t affect the AF frequency.

Background:Currently, a large number of molecular biological and genetic markers are known to be involved in the development of osteoarthritis (OA). The mammalian target of rapamycin (mTOR) signaling pathway is responsible for chondrocyte proliferation, cartilage matrix production, and cell growth. OA is characterized by increased mTOR synthesis, which is accompanied by an increase in proliferative activity and destruction of chondrocytes. Obesity is an important factor in the progression of knee OA. The study of mTOR expression in patients with OA and obesity is an urgent task in the development of personalized OA therapy.Objectives:To determine the expression of mTOR in patients with knee OA in combination with obesity and normal body weight. To evaluate the effect of mTOR on the clinical manifestations of OA in patients with different body mass index (BMI).Methods:The study included 73 female patients aged 45-65 y.o. with Kellgren-Lawrence stage II-III knee OA. The patients were divided into 2 groups: group 1 (n=50) with obesity (BMI > 30 kg / cm2) and group 2 (n=23) with normal or increased body weight (BMI < 30 kg/cm2). The average age of patients with obesity is 56.5 ± 5.87 years, without obesity - 58.7 ± 5.43 years. Clinical manifestations were evaluated by a WOMAС. RNA was isolated from the patients ‘ blood samples, which was used to determine the expression of mTOR.Results:Patients with knee OA with and without obesity did not differ in age. OA develops at an earlier age in obese patients, than in non-obese patients (p < 0.001). Patients from 1 group had a high BMI > 30 kg/m2 at the onset of OA. Obese patients had more severe knee OA is significantly more often detected: Kellgren-Lawrence stage III was determined in 10% of obese patients and in 4.35% - without obesity (p < 0.001). Significantly higher values of the WOMAC index pain, stiffness, joint functional failure, and total WOMAC were observed in obese patients (p = 0.006, p = 0.039, p = 0.037, and p = 0.014, respectively). Obese patients had higher VAS pain scores (p < 0.05) compared to patients with a lower BMI. Obese patients had a higher mTOR expression (p < 0.05) of 8.02±8.62, compared to non-obese patients. High mTOR expression was associated with VAS knee pain (r=0.78; p < 0.05) and WOMAC pain (r=0.89; p<0.05) in obese patients (Table 1).Table 1.Correlation of m-TORParametersmTOR (1 group, n=50)mTOR (2 group, n=23)Body weightр > 0,05р > 0,05Pain (VAS)r=0,78; р<0,05p = 0,07; r = 0,45Pain (WOMAC)r=0,89; р<0,05р > 0,05Total WOMACр > 0,05р > 0,05Conclusion:Our study showed that patients with obesity and knee OA have higher rates of mTOR expression, compared to patients with normal body weight. High mTOR expression correlates with the severity of knee pain in obese patients. Thus, the evaluation of mTOR expression in obese patients and knee OA plays an important role in predicting the severity of clinical manifestations of OA, and may influence the choice of personalized therapy tactics for such patients.Disclosure of Interests:None declared
