Background: Autonomic dysfunction is one of the major complications in noncommunicable diseases, and there are studies to prove yoga practice improves cardiac autonomic function. So, this present study was done to compare the autonomic functions among yoga practitioners and nonyoga practitioners. Methods: This cross-sectional comparative study was initiated among 68 healthy volunteers of both sexes, after recruiting them based on inclusion and exclusion criteria in the age group of 17–30 yrs. The autonomic reactivity tests like resting heart rate, response of heart rate to standing, Valsalva maneuver, and response of heart rate to deep breathing, response of BP to standing, and sustained hand-grip were done. Results: In the autonomic reactivity test, resting heart rate (80.92 ± 11.76 vs 69.24 ± 10.64) and sustained handgrip (16.30 ± 4.53 vs 10.20 ± 3.67) significantly decreased ( P < 0.05) in the participants of the yoga group compared to control group. Deep breathing test, Valsalva maneuver, 30:15 ratio in lying to standing, and BP response to standing test did not show any significant difference between the groups ( P > 0.05). Conclusion: The present study revealed diminished sympathetic activity and improved parasympathetic activity among the regular yoga practicing participants. It can be practiced regularly to reduce stress and prevent lifestyle-associated disorders in the future.

Background: Blood group plays a unique role in revealing the identity of an individual. Several studies have expressed variations in bleeding tendencies among individuals with various ABO blood groups. Hence a study was done to the find association of bleeding and clotting time with this blood group. Materials and Methods: This study had a cross-sectional study design and was done among 250 young adults. Slide agglutination method was used to assess ABO blood group; while Dukes and capillary tube method were used to determine bleeding and clotting time respectively. Chi-square analysis was done to analyze its association with blood group. Results: Blood group O (38.4%) was found to be the major blood group among both genders, followed by B (34%), A (19.2%), AB (0.08%). Bleeding time of more than 4 minutes was found in both O and B group but the result was statistically not significant (p=0.85). Clotting time of more than 6 minutes was found again in both O and B groups and the difference was not significant (p=0.96). Bleeding time was found to be higher in males while Clotting time was found to be more prolonged in females however the difference was statistically less significant (p>0.05). Conclusion: In this study, results have shown that blood group O was the predominant blood group among the study population and blood group O and B had prolonged bleeding and clotting time compared to other groups. Based on gender, females had higher clotting time compared to males.

Introduction: Vascular Calcification (VC) is considered as a cardiovascular risk marker in Chronic Kidney Disease (CKD) patients. VC is a process characterised by thickening and loss of elasticity of muscular arteries walls. The three pathological forms of cardiovascular disease in CKD are cardiac geometry, atherosclerosis and arteriosclerosis of the large vessels (carotid artery or aorta). Aim: To evaluate VC as a cardiovascular risk marker in CKD patients. Materials and Methods: This cross-sectional study was conducted in the Nephrology Department at Sri Ramachandra Medical College and Research Institute, Chennai, Tamil Nadu, India, from November 2019 to December 2020. The study included 27 CKD patients who were on maintenance haemodialysis. The participants were 20 to 70 years of age, and of both genders. The Intima Media Thickness (IMT) was assessed by ultrasonography. Peak Systolic Velocity (PSV) measurement was done using doppler ultrasonography. Both the measurements were done on common Carotid Artery (CCA), and Internal Carotid Artery (ICA) on both sides of the neck. Student’s t-test and Chi-square test was used in this study. Data were expressed as mean±SD. The p-value <0.05 was considered as statistically significant. Results: Out of 27 study participants, 20 (74%) were male and females were 7 (26%), with mean age of 48 years. There was significant increase in IMT of the ICA on the right side of the neck compared to left side (p-value=0.01). Also, there was significant increase in PSV of ICA on the right side compared to left side of the neck (p-value=0.04). There were no statistically significant differences in IMT and PSV when CCA on the right side was compared to that of the left side of the neck. Conclusion: The IMT was increased in ICA and CCA. But there was statistically significant difference only in ICA, where it was more prominent on the right side compared to left side. CKD patients on haemodialysis management could have the risk factors in the form of increased IMT predisposing them to early mortality from cardiovascular complications.
