Abstract Introduction: Leucocyte telomerase length (LTL) are inked to accelerate aging and premature mortality. In this research, we aimed to explore the relations between biochemical and anthropometry markers and LTL in Asian Indian women with prediabetes.Methods: In this study, 797 prediabetic women (aged 20-60 years, obese, 492; non obese, 305) were recruited. Demographic and clinical profiles, medical history, skin exposure and duration of sunlight exposure were determined. Anthropometry, fasting blood glucose and serum 25-hydroxyvitamin D [25(OH) D] were evaluated. LTL was quantified by a quantitative polymerase chain reaction (qPCR). The study subjects were separated into quartiles groups according to the LTL.Results: The average telomerase length (T/S) ratio was significantly decreased with increasing age. The average telomerase length (T/S) ratio was significantly shorter in obese women with prediabetes (p<0.05). Univariate and multivariable linear regression analysis after adjustment for age, family income, education and hypertension showed that LTL was inversely correlated with body mass index (BMI), waist and hip circumference, waist-hip and waist-to-height ratio, and truncal skinfolds (subscapular, lateral thoracic, and subscapular/triceps ratio, central and total). Multivariable linear regression analysis identified BMI (93%, p<0.0001), central (92%, p<0.0001) and total skinfolds (90%, p<0.0001) as independent predictors of LTL. Conclusions: Besides age, obesity, and subcutaneous adiposity (predominantly truncal) are major contributors to telomerase shortening in Asian Indian women with prediabetes.

Abstract Left atrial (LA) remodeling is closely related to cerebral stroke, but the relationship between impaired deformability of LA in early stages and stroke/TIA is not clear. The aim of this study was to evaluate the changes of LA deformability and its relationship with stroke/TIA events by using Speckle Tracking echocardiography. In 365 patients with paroxysmal atrial fibrillation (AF) (318, Non stroke/TIA; 47, stroke/TIA), comprehensive echocardiography was performed by using speckle tracking imaging to calculate mean LA longitudinal strain and strain rate values from apical four chamber view, apical two chamber view and apical three cavity view. The patients in stroke/TIA group had greater ages, a greater proportion of men and lower LA strain rate during left ventricular (LV) early diastole (SRE), and the difference was statistically significant(p<0.05). In the univariate linear regression analysis, the following clinical and conventional echocardiographic parameters each had a significant linear correlation with SRE(p<0.001), they were E/A ratio, LA volume index, body mass index, mean E/e′, LV ejection fraction, age, proportion of hypertension. Through a multiple linear regression analysis, the results show that there is a linear dependence between SRE and E/A ratio, LA volume index and Body mass index. The regression equation is y=-1.430-0.394X1+0.012X2+0.019X3(p<0.001) (y,SRE; X1,E/A ratio; X2,LA volume index; X3,Body mass index).In the multivariate logistic regression analyses, SRE and Sex ratio were independently risk factors stroke/TIA. (SRE, OR 2.945, 95% CI 1.092-7.943, p= 0.033; Sex, OR 0.462, 95% CI 0.230-0.930, p = 0.031)In patients with paroxysmal AF, SRE could reflect the impaired deformability of LA in early stages, and it was associated with the risk of stroke/TIA.

Objective Myonectin, a newly discovered myokine, enhances fatty acid uptake in cultured adipocytes and hepatocytes and suppresses circulating levels of free fatty acids in mice. Recent studies showed that serum myonectin concentration is negatively correlated with obesity. This study was undertaken to evaluate the change of serum myonectin in obese patients after laparoscopic sleeve gastrectomy. Methods This study was performed in a population of 42 obese and 58 control subjects from April of 2018 to December of 2019. All obese subjects underwent laparoscopic sleeve gastrectomy. Anthropometric measurements, lipid profiles, HbA1c and serum myonectin were assessed at baseline and six months after laparoscopic sleeve gastrectomy. Results Serum myonectin concentrations were significantly lower in the obese patients than in the controls. Serum myonectin concentrations were increased at six months after laparoscopic sleeve gastrectomy. Simple linear regression analysis indicated that serum myonectin was negatively correlated with weight, waist circumference, hip circumference, body mass index, fasting plasma glucose, homeostasis model assessment of insulin resistance and HbA1c. Only body mass index was still inversely correlated with serum myonectin after multiple linear regression analysis. Conclusion Serum myonectin is correlated with obesity and increased after laparoscopic sleeve gastrectomy.

AbstractObjectivesPrevious cross-sectional studies have demonstrated obesity rates in children with CHD and the general paediatric population. We reviewed longitudinal data to identify factors predisposing to the development of obesity in children, hypothesising that age may be an important risk factor for body mass index growth.Study designRetrospective electronic health records were reviewed in all 5–20-year-old CHD patients seen between 2011 and 2015, and in age-, sex-, and race/ethnicity-matched controls. Subjects were stratified into aged cohorts of 5–10, 11–15, and 15–20. Annualised change in body mass index percentile (BMI%) over this period was compared using paired Student’s t-test. Linear regression analysis was performed with the CHD population.ResultsA total of 223 CHD and 223 matched controls met the inclusion criteria for analysis. Prevalence of combined overweight/obesity did not differ significantly between the CHD cohort (24.6–25.8%) and matched controls (23.3–29.1%). Univariate analysis demonstrated a significant difference of BMI% change in the age cohort of 5–10 (CHD +4.1%/year, control +1.7%/year, p=0.04), in male sex (CHD +1.8%/year, control −0.3%/year, p=0.01), and status-post surgery (CHD 2.03%/year versus control 0.37%, p=0.02). Linear regression analysis within the CHD subgroup demonstrated that age 5–10 years (+4.80%/year, p<0.001) and status-post surgery (+3.11%/year, p=0.013) were associated with increased BMI% growth.ConclusionsPrevalence rates of overweight/obesity did not differ between children with CHD and general paediatric population over a 5-year period. Longitudinal data suggest that CHD patients in the age cohort 5–10 and status-post surgery may be at increased risk of BMI% growth relative to peers with structurally normal hearts.

Aim. To determine the predictors of hypertension among nonpregnant females attending a health promotion clinic. Design and Setting. A cross-sectional study was conducted during March to June 2016, at the National Institute of Cancer Prevention and Research, India. Methods. The study included 319 nonpregnant females of age 20–70 years. Demographics such as age, literacy, and income were noted. History regarding use, frequency, and quantity of smokeless tobacco was taken. Height, weight, and blood pressure were measured and body mass index was calculated. Statistical Analysis. Pearson’s product-moment correlation coefficient was calculated between each of the variables of age, smokeless tobacco consumption, and body mass index versus systolic and diastolic blood pressure, respectively. The linear as well as multiple linear regression analysis was employed to identify the risk factors for hypertension. Results. A univariate linear regression analysis showed that age, smokeless tobacco consumption, and body mass index were associated with systolic blood pressure (P value < 0.001 for each). For diastolic blood pressure, high body mass index was a predictor. Multiple linear regression analysis showed that both systolic and diastolic hypertension were associated with high body mass index and low level of education. Moreover, the systolic hypertension was associated with higher age and smokeless tobacco use. Conclusion. Health promotion requires control of body mass index and smokeless tobacco cessation for preventing hypertension and its complications.

Objectives Mechanisms of walking limitation in arterial claudication are incompletely elucidated. We aimed to identify new variables associated to walking limitation in patients with claudication. Methods We retrospectively analyzed data of 1120 patients referred for transcutaneous exercise oxygen pressure recordings (TcpO2). The outcome measurement was the absolute walking time on treadmill (3.2 km/h, 10% slope). We used both: linear regression analysis and a non-linear analysis, combining support vector machines and genetic explanatory in 800 patients with the following resting variables: age, gender, body mass index, the presence of diabetes, minimal ankle to brachial index at rest, usual walking speed over 10 m (usual-pace), number of comorbid conditions, active smoking, resting heart rate, pre-test glycaemia and hemoglobin, beta-blocker use, and exercise-derived variables: minimal value of pulse oximetry, resting chest-TcpO2, decrease in chest TcpO2 during exercise, presence of buttock ischemia defined as a decrease from rest of oxygen pressure index ≤15 mmHg. We tested the models over 320 other patients. Results Independent variables associated to walking time, by decreasing importance in the models, were: age, ankle to brachial index, usual-pace; resting TcpO2, body mass index, smoking, buttock ischemia, heart rate and beta-blockers for the linear regression analysis, and were ankle to brachial index, age, body mass index, usual-pace, decrease in chest TcpO2, smoking, buttock ischemia, glycaemia, heart rate for the non-linear analysis. Testing of models over 320 new patients gave r = 0.509 for linear and 0.575 for non-linear analysis (both p < 0.05). Conclusion Buttock ischemia, heart rate and usual-pace are new variables associated to walking time.

SummaryThe aim of this study was to investigate the socioeconomic and demographic factors influencing the body mass index (BMI) of non-pregnant married Bangladeshi women of reproductive age. Secondary (Hierarchy) data from the 2011 Bangladesh Demographic and Health Survey, collected using two-stage stratified cluster sampling, were used. Two-level linear regression analysis was performed to remove the cluster effect of the variables. The mean BMI of married non-pregnant Bangladeshi women was 21.60±3.86 kg/m2, and the prevalence of underweight, overweight and obesity was 22.8%, 14.9% and 3.2%, respectively. After removing the cluster effect, age and age at first marriage were found to be positively (p<0.01) related with BMI. Number of children was negatively related with women’s BMI. Lower BMI was especially found among women from rural areas and poor families, with an uneducated husband, with no television at home and who were currently breast-feeding. Age, total children ever born, age at first marriage, type of residence, education level, level of husband’s education, wealth index, having a television at home and practising breast-feeding were found to be important predictors for the BMI of married Bangladeshi non-pregnant women of reproductive age. This information could be used to identify sections of the Bangladeshi population that require special attention, and to develop more effective strategies to resolve the problem of malnutrition.

Atherosclerotic Risk Factors

Correlations between aerobic capacity, obesity, and atherosclerotic risk factors were evaluated in adolescents with low-to-moderate levels of physical fitness. Subjects with higher levels of fitness had a more favorable risk profile with decreased body mass index, lower systolic and diastolic blood pressure and plasma triglyceride levels, and higher plasma high-density lipoprotein-cholesterol levels. Simple linear regression analysis revealed an association between body mass index and blood pressure, plasma triglyceride and plasma highdensity lipoprotein-cholesterol. The level of aerobic fitness as determined by exercise duration was also associated with the same atherosclerotic risk factors. However, multiple linear regression analysis demonstrated that body mass index provided the largest explanation, by those variables examined, of the interindividual variance in blood pressure, plasma triglyceride, and high-density lipoprotein-cholesterol. Aerobic fitness contributed only minimally to the variation in these risk factors. These findings suggest that if aerobic conditioning is used to modify atherosclerotic risk factors, it should be accompanied by a reduction in weight in adolescents with low-to-moderate levels of physical fitness.
