[Diet therapy program for weight loss and assessment of its effectiveness in overweight and obese persons].

The basic method of obesity treatment is diet therapy aimed at long-term maintenance of negative energy balance by restricting the caloric intake of the diet. The aim - to evaluate the effectiveness of the diet therapy program for weight loss with the use of a complex of amino acids and glucomannan. Material and methods. To conduct the study, in accordance with the inclusion and exclusion criteria, a sample of 33 overweight or obese people was formed, of which 30 people (16 men and 14 women) took part in the study. The age of the persons included in the study ranged from 20 to 59 years (average 41.0±1.73 years), body mass index- from 26.4 to 45.5 kg/m2 (average 35.5±0.8 kg/m2), waist circumference as a criterion for abdominal obesity - 110.4±2.4 cm. Participants three times a day (7.00-9.00, 12.00-14.00 and 16.00-18.00) received within 14 days 15 g of powder dissolved in 200 ml of water containing whey protein concentrate, potassium (618 mg in the form of citrate), glucomannan, taurine (290 mg), zinc (2.5 mg in the form of sulfate), vitamins B6 (1.4 mg) and B12 (3 mcg), and 2 capsules containing L-isoleucine (340 mg), L-ornithine-alpha-ketoglutarate (290 mg), L-citrulline-DL-malate (290 mg) and L-tryptophan (80 mg). In the evening, the main meal was dinner, which included a protein dish with vegetables and herbs. The energy value of the evening meal was 400 kcal (1675 kJ), the proportion of protein, fat and carbohydrates was 40, 30 and 30%, respectively, of the calorie content of the evening meal. Results. It was shown that the use of a 14-day course of the diet therapy program to reduce body weight was accompanied by a statistically significant decrease in body weight on average 6.3% of the initial level, an improvement in body composition indicators (a rather pronounced decrease in body fat mass by 9.2%, p<0.001, with a smaller decrease in lean body mass and skeletal muscle mass, respectively by 3.9 and 4.1%, p<0.001) and metabolic blood parameters (a decrease in serum glucose concentration, total cholesterol, triglycerides, total bilirubin and gamma-glutamyltransferase by 12.5, 15.0, 35.0, 22.8 and 34.6% respectively). Conclusion. Application of the diet therapy program for weight loss «Non-invasive liposuction¼ allows us to recommend its use in obese patients in order to increase the effectiveness of therapeutic and prophylactic measures in correcting excess body weight, improving the parameters of carbohydrate and lipid metabolism, and the functional state of the biliary system.

[Selenium metabolism in patients with severe multiple trauma].

GOAL OF THE STUDY: To define a relation between the selenium level and the risk of the development of nosocomial pneumonia in patients with severe multiple trauma depending on the trauma severity and the volume of blood loss. MATERIALS AND METHODS: We measured serum selenium concentration in 40 patients with severe multiple trauma. The ISS score was used to estimate the trauma severity. Patients were divided into 2 groups: group I--25 patients without pneumonia, group II--15 patients with pneumonia. The volume of blood loss was estimated in each group. The oxidative stress was estimated by means of the antioxidant index. RESULTS: For selected groups the significant difference (P < 0.05) in the volume of blood loss was detected. It was shown the significant decrease of selenium concentration (P < 0.05) in both groups in comparison with control for all testing time points (the 6-12 hrs, 24 hrs, 3 and 5-7 days). The mean of selenium concentration in group II was significantly lower in comparison to the group I. A significant difference of selenium concentrations (P < 0.05) between groups were detected on the 6-12 hrs and day 3 from the trauma onset. The antioxidant index was significantly lower in the group II within the 6-12 hrs, 12-24 hrs and 5-7 days (P < 0.05) in comparison to group I. CONCLUSIONS: The severe multiple trauma and severe blood loss lead to a selenium deficiency in the blood serum starting with the first hours from the trauma onset, which leads to the critical level of selenium concentration by the Ist day's end after trauma. It also leads to a pronounced oxidative stress that is reflected in the antioxidant index dynamics. Thus serum selenium concentration may be included in the set of the early prognostic detectors to detect infectious pulmonary complications development at severe multiple trauma, and it could be the basis for the decision to take early prophylaxis using selenium medications.

[Body composition in patients with different degree of obesity before and after dietetic correction].

The study included 400 patients with I-III obesity degree. All patients were tested before and after hypocaloric diet with energy value of 1600 kcal/day within 2 weeks. The bioimpedance analysis was spent on device "Inbody 720". The application of the hypocaloric diet is accompanied by clinically significant decrease in body weight in patients with obesity mainly due to the fatty component and visceral fat area and positive dynamics of clinical and biochemical parameters.

[Food status peculiarities, anthropometric, clinica and biochemical indices at professional sportsmen].

Under steady state conditions in 66 athletes involved in weightlifting, bodybuilding, judo and taekwondo have studied features of the metabolic status. Data on matter-of-fact nutrition, body weight content within the inter-competition period, energy exchange, clinical and biochemical indices and physical acceptability indices were analyzed. As a result, the decrease indexes of metabolism at all the sportsmen and high-level caloric value at sportsmen who are engaged in weightlifting, which corresponds their energy expenditures, was revealed.
