Association of blood pressure and BMI to corrected QT interval in young adults

Hypertension is often associated with obesity. Uncontrolled hypertension can lead to uncorrected cardiac dysautonomia that makes cardiac repolarization abnormally prolonged. Modern dietary habits, stress, and bad lifestyle habits make young adults vulnerable to hazards of health. We planned to study the association of body mass index (BMI) and blood pressure (BP) with corrected QT (QTc) intervals in young adults. After obtaining the written informed consent, 171 subjects were randomly selected in the age group of 18–35 years. A general history and physical examination were done before recording the BMI and BP. A 12-lead electrocardiogram was recorded and QTc calculated using Bazett’s formula. The values obtained were compared and statistical analysis done. Of the 171 subjects 14.03% were hypertensive. The QTc interval was found to be prolonged in females and it is prolonged with age, BMI, and BP. QTc was significantly increased among the prehypertensive and hypertensive group and with the overweight and (or) obese BMI group compared with the normotensives and normal BMI group suggesting an altered autonomic homeostasis. This warrants lifestyle modification at a younger age to reduce the cardiovascular risk. </jats:p

ASSOCIATION OF BLOOD PRESSURE AND BMI WITH QTc INTERVAL IN YOUNG ADULTS

Background: Hypertension is often associated with obesity. Uncontrolled hypertension can lead to uncorrected cardiac dysautonomia that makes cardiac repolarization abnormally prolonged. Modern dietary habits, stress and bad life style habits makes young adults vulnerable to hazards of health. Purpose: So we planned to study the association of BMI (Body Mass Index) and BP ( Blood pressure) with QTc (corrected QT interval) in young adults. Materials and methods: After obtaining the written informed consent, 171 subjects were randomly selected in the age group of 18-35 years. A general history and physical examination was done before recording the BMI and BP. A 12 lead ECG was recorded and QTc calculated using Bazett’s formula. The values obtained were compared and statistical analysis done. Results: Of the 171 subjects 14.03% were hypertensive. The QTc interval is found to be prolonged in females and it is prolonged with age, BMI and BP. Conclusion: QTc was significantly increased among the prehypertensive and hypertensive group and with overweight / obese BMI group compared to the normotensives and normal BMI group suggesting an altered autonomic homeostasis. This warrants lifestyle modification at a younger age to reduce the cardiovascular risk.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Enhancement approach for liver lesion diagnosis using unenhanced CT images

Hepatocellular carcinoma, the primary liver cancer and other liver‐related pathologies are diagnosed with the help of contrast enhanced computed tomography (CECT) images. The CECT imaging technology is claimed to be an invasive technique, as the intravenous contrast agent injected prior to computed tomography (CT) acquisition is harmful and is not advised for patients with pre‐existing diabetes and kidney disorders. This study presents a novel enhancement technique for the diagnosis of liver lesions from unenhanced CT images by means of fuzzy histogram equalisation in the non‐sub‐sampled contourlet transform domain followed by decorrelation stretching. The enhanced images obtained in this study substantiate that the proposed method improves the diagnostic value from the unenhanced CT images thereby providing an alternate painless solution for CT acquisition for the subset of patients mentioned above. Another major highlight of this work is the characterisation of lesions from the enhanced output for five different classes of pathology. The obtained results presented in this study demonstrate the potency of the proposed enhancement technique in achieving an appreciable performance in lesion characterisation. The images used for this research study have been obtained from Jawaharlal Institute of Medical Education and Research Puducherry, India

Experimental Investigation on Mechanical Behaviour of Kevlar and Ramie Fibre Reinforced Epoxy Composites

Natural fibre composites have been replacing synthetic fibre composites in practical applications for the last several years because of the features such as low densities, low weight, relatively inexpensive, recyclability, and excellent mechanical qualities unique to the substance. Thus, the current study examines how Kevlar/Ramie/Nano SiC hybrid fibre reinforced composites are made and their mechanical properties, and it compares them to those made using a single natural fibre reinforced composite. It was found that natural fibre composite densities and hardness were all within acceptable ranges by performing composites’ tensile and flexural strength tests. The hand-lay-up technique used ASTM standards samples to construct the composite specimens with various fibre weight percentages. Increase in mechanical characteristics was achieved by adding the glass and the epoxy fibres into the epoxy matrix. The hybrid composite’s performance is promising, especially those of individual fibre-reinforced composites.</jats:p
