Introduction: This study explored the relationship between first-time or repeat participation at a sports education camp and demographic variables of gender, age, race or ethnicity, measures of self-perception, body mass index (BMI), and physical activity in participants’ communities. Methods: The study was a secondary data analysis of interview and BMI data for youths with visual impairments (i.e., those who are blind or have low vision) who attended a sports education camp in one of 12 states in the years 1989, 1996, and 2000–2010. Results: The short-term intervention model of a sports education camp had a positive effect on participants’ perceptions of themselves. This result was more pronounced for boys and for youths with some usable vision. Involvement in a sports education camp did not tend to translate to increased involvement in sports in a student’s community. The mean BMI of first-time participants was consistent across gender, race or ethnicity, and vision category, and the BMI of first-time participants tended to be higher according to the age of the participant. Discussion: The findings revealed that the short-term intervention model of a sports education camp is highly effective in increasing self-perception for youngsters with vision impairments. Implications for practitioners: For youths with visual impairments who might be experiencing reduced social interaction, decreased self-perception or increased BMI involvement in a sports education camp is a short-term intervention that can positively impact these effects.

Introduction: A crucial component of the effort to meet the growing demand for blood is the recruitment and retention of young novice blood donors. Reducing postdonation syncopal reactions could have a beneficial impact on donor convenience, safety, and desire to donate again. Aim: To evaluate the effectiveness of predonation hydration over standard blood donation in the prevention or decrease in severity of postdonation Vasovagal Reactions (VVR) in hydrated blood donors in comparison with the non hydrated group. Materials and Methods: The randomised controlled trial was conducted on 953 first time voluntary blood donors. Donors in the intervention arm drank 250 mL water 30 minutes before blood donation, while those in the control group did not receive any intervention. Blood was collected by standard protocol. Outcome, VVR, if present was graded as mild, moderate, and severe. Analysis of results were done using Statistical Package for the Social Sciences (SPSS) version 16.0. A sensitivity analysis was also done to consider the dropouts from the study. Results: A total of 900 participants were included in the study, of which 443 were controls and 457 were cases. An effect size of 6.1%, a Relative Risk (RR) of 0.54 {95% Confidence Interval (CI)=0.36-0.81} and a risk reduction of 45% was arrived at, pointing to a protective role for predonation hydration in preventing VVR. There was a significant reduction in the severity of VVR in the predonation hydration group compared to the standard blood donation group (p-value=0.002). The protective effect of hydration on decreasing the occurrence and severity of VVR had statistical support in males in the moderate and severe grades (p-value=0.017). A similar statistical significance was not established in females (p-value=0.173). Sensitivity analysis did not reveal a difference in the statistical significance of variables between compared groups. Conclusion: Predonation hydration was found to be effective in preventing and decreasing the severity of VVR in novice blood donors.

Ожирение является важнейшим фактором риска развития сахарного диабета 2 типа (СД2). Гепатоцитарный ядерный фактор 1 β (HNF1B) контролирует глюкостатическую функцию островков Лангерганса поджелудочной железы и ассоциирован с развитием СД2 в европейской и азиатской популяциях. Однако исследований, оценивающих роль генетических вариантов HNF1B в формировании предрасположенности к СД2 в русской популяции, на сегодняшний день не проводилось. Целью настоящей работы стало изучение ассоциации полиморфного варианта rs4430796 (A>G) в интроне гена HNF1B с показателями гликемического профиля и редокс-гомеостаза, а также риском развития СД2 у жителей Центральной России, с учетом их пола и индекса массы тела. В исследование включено 3206 человек, из них 1579 больных СД2 и 1627 условно здоровых добровольцев. Генотипирование проводили с использованиеми технологии iPLEX на геномном времяпролетном масс-спектрометре MassArray 4 (Agena Bioscience). Впервые в русской популяции установлена взаимосвязь полиморфизма rs4430796 гена HNF1B с повышенным риском развития СД2 (OR 1,24, 95CI 1,05-1,47, р=0,011). Стратифицированный анализ по полу обнаружил, что выявленная ассоциация характерна только для женщин с избыточной массой тела (OR 1,54, 95CI 1,06-2,22, р=0,02) и ожирением (OR 2,07, 95CI 1,14-3,77, р=0,047) и отсутствует у лиц с нормальной массой тела вне зависимости от пола. Изучаемый SNP ассоциирован с повышенным содержанием перекиси водорода (р=0,012) и более низким уровнем общего глутатиона плазмы (р=0,041) у женщин, тогда как у мужчин с СД2 генотип G/G связан со снижением концентрации С-пептида (р=0,004) и повышением концентрации глюкозы крови (р=0,015). Биоинформатический анализ подтвердил отрицательный эффект аллеля G на экспрессию HNF1B, а также выявил его связь с гиперметилированием гена в различные периоды жизни, что обусловливает низкую экспрессию гена HNF1B у носителей минорного аллеля rs4430796-G. Таким образом, нами впервые установлено, что полиморфный вариант гена HNF1B rs4430796 ассоциирован с предрасположенностью к СД2 в русской популяции, при этом его связь с заболеванием имеет пол-специфический характер и зависит от индекса массы тела. Obesity is a critical risk factor for type 2 diabetes mellitus (T2D). Hepatic nuclear factor 1 β (HNF1B) controls the glucostatic function of pancreatic islets of Langerhans and is associated with the development of T2D in the European and Asian populations. However, studies evaluating the contribution of genetic variants at HNF1B to the pathogenesis of the disease in Russian population have not been conducted to date. The aim of this work was to study the association of the polymorphic variant rs4430796 (A>G) in the intron of the HNF1B gene with parameters of glycemic profile and redox homeostasis, as well as the risk of developing T2D in citizens of Central Russia, taking into account their gender and body mass index. The study included 3206 participants, 1579 patients with T2D and 1627 healthy volunteers. Genotyping was performed using iPLEX technology on a genomic time-of-flight mass spectrometer MassArray 4 (Agena Bioscience). For the first time in the Russian population, the relationship of the rs4430796 polymorphism at the HNF1B gene with an increased risk of developing T2D (OR 1,24, 95CI 1,05-1,47, p=0,011) was established. A gender-stratified analysis found that the association is characteristic only for females with overweight (OR 1,54, 95CI 1,06-2,22, p=0,02) and obesity (OR 2.07, 95CI 1,14-3,77, p=0.047) and is absent in individuals with normal body weight, regardless from the gender. The studied SNP is associated with an increased content of hydrogen peroxide (p=0,012) and a lower level of total plasma glutathione (p=0,041) in females, whereas in diabetic males the G/G genotype is associated with a decrease in the concentration of C-peptide (p=0,004) and an increase in blood glucose concentration (p=0,015). Bioinformatic analysis confirmed the negative effect of the alternative G allele on the expression of the HNF1B gene, as well as its relationship with hypermethylation of the gene at different periods of life, which leads to low expression of HNF1B in carriers of variant rs4430796. Conclusions: It was found for the first time that the polymorphic variant rs4430796 of the HNF1B gene is associated with a predisposition to T2D, whereas its relationship with the disease is sex-specific and depends on body mass index.
