Frequency of consumption of specialty food products by sports university students and violation of the principles of their introduction to the diets

Purpose: estimate actual diet of college basketball players, including frequency of consumption of specialty foods.Materials and methods: 25 male students sports university basketball were examined (average age 20.9 ± 1.8 years). Actual nutrition was studied by the frequency method using the computer program “Analysis of Human Nutritional Status”. Data on the frequency and quantity of consumed specialized food products for the nutrition of athletes (SFP) and biologically active food additives were studied using a questionnaire.Results: the daily energy value of the diet averaged 3205 ± 520 kcal/day, 135 ± 36 g of protein per day, 155 ± 25 g/day of fats and 317 ± 72 g/day of carbohydrates; unoptimal diet structure was revealed — fats predominate from the daily energy value, carbohydrate and protein intake was low. There is a discrepancy between daily food intake (low consumption of fruits, vegetables, bread, fish) and the Order of the Ministry of Sports of the Russian Federation dated October 30, 2015 No. 999 “On requirements approval for ensuring the sports reserves training for sports teams of the Russian Federation” requirements. Basic diet revealed a high average daily content of iron (19 ± 6 mg/day), vitamins A (1057 ± 729 µg ret. equiv) and C (153 ± 101 mg/day). Data on the frequency of taking SPPs and dietary supplements are provided. At the same time, content of some nutrients in them exceeded the upper permissible consumption levels.Conclusion: it is advisable to regularly increase the awareness of coaches and athletes about the rational nutrition principles through the introduction of educational programs into sports practice

Forecasting of Brucellosis Morbidity Rates in the Russian Federation Using Wald Method

Objective of the study is to conduct epidemiological analysis of official statistical data on brucellosis morbidity rates over the period of 2005–2014 in different constituent entities of the Russian Federation, using Wald method. Materials and methods. Utilized were recording and reporting documents of the Federal Service for Surveillance in the Sphere of Consumers Rights Protection and Human Welfare, FBHI “Federal Center of Hygiene and Epidemiology” of the Rospotrebnadzor, and WHO information resources.Results and conclusions. Studies of peculiarities of epidemic process development over the long-term period have allowed for identification of entities that are the most affected by the diseases. The results obtained on the morbidity rates in the Russian Federation over the period of 2005–2014 testify to the fact that first comes North Caucasian Federal District (NCFD) (62 %), next go Siberian (SbFD) (16 %) and Southern (SFD) (13 %) Federal Districts, second and third lines of the list respectively. Other regions account for 9 % of the load. The largest share of morbidity in NCFD entities belongs to the Republic of Dagestan – 62 %. Thereat, annual increment rate is 5.54 cases, which points to stabilization and some downward trend. Application of this morbidity rate prediction tool provides for in-time planning of clinical-diagnostic, prophylactic, and anti-epidemic measures in brucellosis foci. Wald method for forecasting of morbidity can be used for other infectious diseases too

How to Search for Doubly Charmed Baryons and Tetraquarks

Possible experimental searches of doubly charmed baryons and tetraquarks at fixed target experiments with high energy hadron beams and a high intensity spectrometer are considered here. The baryons considered are: $\Xi_{cc}^{+}$ (ccd), $\Xi_{cc}^{++}$ (ccu), and $\Omega_{cc}^{+}$ (ccs); and the tetraquark is T ($cc\bar{u}\bar{d}$). Estimates are given of masses, lifetimes, internal structure, production cross sections, decay modes, branching ratios, and yields. Experimental requirements are given for optimizing the signal and minimizing the backgrounds. The discussion is in the spirit of an experimental and theoretical review, as part of the planning for a CHarm Experiment with Omni-Purpose Setup (CHEOPS) at CERN. The CHEOPS objective is to achieve a state-of-the-art very charming experiment, in the spirit of the aims of the recent CHARM2000 workshop.Comment: 18 pages text (latex), 16 March 1995, presented at "Physics with Hadron Beams with a High Intensity Spectrometer", revised 10 May for more complete bibliography and appropriate references to S.

Genetic landscape in Russian patients with familial left ventricular noncompaction

BackgroundLeft ventricular noncompaction (LVNC) cardiomyopathy is a disorder that can be complicated by heart failure, arrhythmias, thromboembolism, and sudden cardiac death. The aim of this study is to clarify the genetic landscape of LVNC in a large cohort of well-phenotyped Russian patients with LVNC, including 48 families (n=214).MethodsAll index patients underwent clinical examination and genetic analysis, as well as family members who agreed to participate in the clinical study and/or in the genetic testing. The genetic testing included next generation sequencing and genetic classification according to ACMG guidelines.ResultsA total of 55 alleles of 54 pathogenic and likely pathogenic variants in 24 genes were identified, with the largest number in the MYH7 and TTN genes. A significant proportion of variants −8 of 54 (14.8%) −have not been described earlier in other populations and may be specific to LVNC patients in Russia. In LVNC patients, the presence of each subsequent variant is associated with increased odds of having more severe LVNC subtypes than isolated LVNC with preserved ejection fraction. The corresponding odds ratio is 2.77 (1.37 −7.37; p <0.001) per variant after adjustment for sex, age, and family.ConclusionOverall, the genetic analysis of LVNC patients, accompanied by cardiomyopathy-related family history analysis, resulted in a high diagnostic yield of 89.6%. These results suggest that genetic screening should be applied to the diagnosis and prognosis of LVNC patients
