Intradialytic Exercise

Introduction: Although intradialytic exercise is considered a form of “nonpharmacological medicine” for patients receiving maintenance hemodialysis (MHD), this practice has not been widely implemented in most dialysis centers because of clinical limitations. We, therefore, aimed to design an intradialytic exercise training program to improve the implementation of this practice and determine its impact on physical performance and cardiovascular risk factors in patients receiving MHD. Methods: A total of 132 MHD patients at 4 outpatient dialysis units were enrolled and assigned randomly into exercise (n = 67) and control groups (n = 65). During a 2-year period, patients in the exercise group participated in 20-min exercise training sessions within dialysis sessions on 3 days per week. All patients underwent assessments of physical function (6-min walk test) and cardiovascular risk factors (blood pressure [BP], total cholesterol [TC], low-density lipoprotein [LDL], high-sensitivity C-reactive protein [hsCRP], albumin [Alb], hemoglobin [Hb], and erythropoietin [EPO] dose) at the baseline and annually thereafter. Results: Of the participants, 50.8% had completed the study after 2 years. No statistically significant intragroup or intergroup differences were observed in the measures of 6MD, BP, TC, hsCRP, Alb, Hb, and EPO dose. Conclusion: The results suggest that although this low-intensity, nonprogressive intradialytic exercise program may be practical, it was not sufficient to improve physiological function and reduce cardiovascular disease risk factors in patients receiving MHD.

Abstract The present review is designed to provide insight into population-based investigations of cardiovascular risk factors in Latvia. Most of them represent urban, rural and mixed populations. The results are age-standardised using the European Standard Population. All of the studies confirm a high prevalence of cardiovascular risk factors with wide differences across the studies. The differences are not consistent or regular and some of the underlying reasons are discussed. Analysis of the previous studies justifies the need for a nationwide cross-sectional epidemiological study, which in a small country can be carried out in compliance with all the requirements for a population-based epidemiological study.

Mendelian Randomisation

Abstract Mendelian randomisation studies from Asia suggest detrimental influences of alcohol on cardiovascular risk factors, but such associations are observed mainly in men. The absence of associations of genetic variants (e.g. rs671 in ALDH2) with such risk factors in women – who drank little in these populations – provides evidence that the observations are not due to genetic pleiotropy. Here, we present a Mendelian randomisation study in a South Korean population (3,365 men and 3,787 women) that 1) provides robust evidence that alcohol consumption adversely affects several cardiovascular disease risk factors, including blood pressure, waist to hip ratio, fasting blood glucose and triglyceride levels. Alcohol also increases HDL cholesterol and lowers LDL cholesterol. Our study also 2) replicates sex differences in associations which suggests pleiotropy does not underlie the associations, 3) provides further evidence that association is not due to pleiotropy by showing null effects in male non-drinkers and 4) illustrates a way to measure population-level association where alcohol intake is stratified by sex. In conclusion, population-level instrumental variable estimation (utilizing interaction of rs671 in ALDH2 and sex as an instrument) strengthens causal inference regarding the largely adverse influence of alcohol intake on cardiovascular health in an Asian population.

Exercise is advocated in the management of type 1 diabetes (T1D), but the effects of different forms of exercise training on cardiovascular risk factors in T1D still remain unclear. The aim of this study was to conduct a systematic review and meta-analysis on exercise training for cardiovascular risk factors in T1D. Six electronic databases were systematically searched for randomized or non-randomized controlled studies reporting associations between exercise training and cardiovascular risk factors in T1D. Weighted mean differences (WMD) of each cardiovascular risk factor between exercise groups and control groups were calculated using a random effects model. A total of 24 studies reported the effects of exercise training on cardiovascular risk factors. Exercise training increased maximal aerobic power (3.01 mL·kg−1·min−1, 95% confidence interval, CI, 0.94 to 6.38) and reduced glycated hemoglobin (HbA1c; −0.45%, 95% CI −0.73 to −0.17), daily insulin dosage (−0.88 U·kg−1, 95% CI −1.27 to −0.48), and total cholesterol (−0.38 mmol·L−1, 95% CI −0.71 to −0.04). Exercise training did not lead to consistent changes in body mass index (BMI), blood pressure, triglycerides, high-density lipoprotein cholesterol (HDL-C), or low-density lipoprotein cholesterol (LDL-C). In persons living with T1D, exercise training is associated with a beneficial cardiovascular profile, including improvements in lipid profile, glycemic control (decreased daily insulin dosage and HbA1c), and aerobic fitness.

AbstractBackground:Excessive body fat, mainly abdominal fat, is associated with higher cardiovascular risk. However, a fat localisation measurement that would be more indicative of risk in adolescents has not yet been established.Objective:This study was conducted in order to evaluate the correlation between body fat location measurements and cardiovascular disease risk factors in female adolescents.Materials and methods:A total of 113 girls – 38 eutrophic according to their body mass index but with a high percentage of body fat, 40 eutrophic with adequate body fat, and 35 with excessive weight – were evaluated using 15 anthropometrical measurements and 10 cardiovascular risk factors.Results:The central skinfold was the best measurement for predicting variables such as glycaemia and high-density lipoprotein; waist circumference for insulin and homeostasis model assessment; coronal diameter for total cholesterol and low-density lipoprotein; sagittal abdominal diameter for triglycerides and leptin; hip circumference for blood pressure; and the central/peripheral skinfold ratio for homocysteine. The correlation between the measurements and the number of risk factors showed that waist circumference and the waist/stature ratio produced the best results.Conclusions:The results suggest that the body fat distribution in adolescents is relevant in the development of cardiovascular risk factors. Simple measurements such as waist circumference and the waist/stature ratio were the best predictors of a risk of disease and they should therefore be associated with the body mass index in clinical practice in order to identify those adolescents at higher risk.

Abstract Background It is not clear whether resistin, adiponectin and leptin are as closely associated with cardiovascular disease risk in childhood as in adulthood. Methods A survey was performed on elementary school 4 th graders aged 9 to 10 years in Ina-machi, Saitama, Japan to investigate whether resistin, adiponectin and leptin in these children might be associated with cardiovascular risk factors (atherosclerosis index: AI, waist-to-height ratio: W/H ratio, body mass index: BMI), and how the presence of obesity might affect their association. Results A total of 204 boys and 176 girls participated in the survey. Leptin and the leptin-to-adiponectin ratio (L/A ratio) were significantly correlated with the cardiovascular risk factors except AI, and adiponectin was shown to be negatively correlated with all the cardiovascular risk factors examined in the entire study population. While the serum resistin concentration was not found to be significantly different among the boys and girls with or without obesity, the resistin-to-adiponectin ratio (R/A ratio) was found to be significantly different between the obese and non-obese boys but not between the obese and non-obese girls. Among the obese boys, there was a significant correlation between resistin and AI and between the R/A ratio and the cardiovascular risk factors, neither of which was noted among the entire boy population or the non-obese boys. Whereas the R/A ratio was significantly correlated with all the cardiovascular risk factors only in the obese boys. (AI: 0.426, p<0.05, Waist Circumference: 0.545, p<0.01, W/Hr: 0.562, p<0.01, BMI: 0.401, p<0.05) Conclusions Our study findings suggest that school children with high leptin and/or low adiponectin levels are placed at higher cardiovascular risk, regardless of gender. It was also suggested that among boys with obesity as a cardiovascular risk factor, cardiovascular risk was higher in those with high leptin and/or low adiponectin levels, regardless of gender. Furthermore, the findings suggest that resistin is elevated and adiponectin is decreased in obese boys who are placed at higher cardiovascular risk.

The aim of this study was to examine the independent and combined associations of physical activity and different types of screen time in cardiovascular disease risk factors in adolescents. e sample was comprised for 1,045 adolescents (51.7% female) aged 11-17 years old randomly selected. Screen time was considered by the self-related electronic devices such as time watching TV, using computer (PC) and playing videogame (VG). Physical activity was estimated by the number of steps per day (steps/ day) measured by pedometers. Cardiovascular risk factors were sum of triceps and subscapular skin- folds (∑SF), total cholesterol (TC) and blood pressure (BP). Predictors and outcome variables were dichotomized using standardized cut o points. Categories of steps/day and different types of screen time were cross tabulated to the combined analyses. A set of sociodemographic variables was used as confounders. To test the independent and combined associations Chi-square tests (unadjusted) and binary logistic regression (adjusted) were used. TV time was directly and independently associated to ∑SF in females and to TC in males. Steps/day was inversely and independently associated to TC and to BP (not in female). Overall, combined analyses showed that adolescents who did not meet recommendations of steps/day and exposure an excessive screen time are more likely to present cardiovascular risk factor. Public health programs to increase physical activity and reduce screen time, especially TV time, should be developed to improve and prevent cardiovascular health in adolescents.
