ABSTRACT

Background: The current study was designed to evaluate cardio respiratory fitness in terms of VO2max in young healthy males and to correlate between body mass index and cardio respiratory fitness. Methods: One hundred twenty-five apparently healthy male subjects in the age group of 18 to 25 years were included in this study group. Body mass index was measured as weight in kilograms divided by height in meters square. Cardio respiratory fitness in terms of VO2max was predicted by following the protocol of Treadmill Jogging Test (TMJ). Results: There was a highly significant negative correlation between body mass index and VO2max, r = -0.75 p<0.0001. Conclusion: The result suggests that the reduced cardiac performance during progressive work rate exercise in obese individuals. Greater the BMI, more severe will be the functional impairment, suggesting excessive amount of body fat on cardio-respiratory functions and oxygen uptake by working muscles

ABSTRACT

Aim: (i) To assess and compare the cardiovascular response in two sub-maximal exercise tests. (ii) to see correlation between cardiovascular response and anthropometric variables. Method: 125 males 18-25 years underwent first three stages of the original Bruce protocol in one session and exercise according to Treadmill jogging test in another session in randomised order. Heart rate, blood pressure and ECG were recorded before, during and after taking the treadmill test. Results: During the exercise heart rate and systolic BP rose and diastolic BP fell in both the tests. Correlation analysis showed highly significant positive correlation between BMI and pre-exercise systolic BP, post-exercise heart rate and post-exercise systolic BPin both the tests. ECG showed no significant ST/Tor rhythm changes during or after the exercise. Conclusion: Heart rate and BPchanges were more in Bruce submaximal exercise test as compared to treadmill jogging test. Higher BMI was found to be correlated with higher resting systolic BP, higher post-exercise heart rate as well as higher post-exercise systolic BP.

ABSTRACT

Background: Epilepsy is widespread in developing countriescompared to that in developed countries. The reason ofepilepsy in most cases is unknown. Considering the factthat the nutritional status of children in developing countriesis generally poor, our objective was to determine possiblerelationship between nutritional status and epilepsy.Material and methods: Towards this, we gather a datasetof 34 Cases from the Department of Pediatric and as manyControls from the local populace. The age group (5-8.5 years),sex, and gender data is also augmented with educationaland socioeconomic history along with the results of clinicalexaminations, such as, weight, height and body mass index.Results: Our statistical results unveil insignificantdifference in socioeconomic status and educational levels inbetween the parents of Cases and Controls. Additionally, asignificantly higher value of anthropometric measurementsin Controls is observed compared to that of the Casesi.e.Height (117.38±6.05 vs. 112.21±6.82 cm; p value 0.002),Weight (21.29±2.83 vs. 18.14±2.94 kg; p value <0.001) andBody mass index(15.39±1.03 vs.14.33±1.26 kg/m2; p value<0.001).Conclusion: Our results show that generalized epilepsymay have effect on growth and development of children,reflecting that nutritional programs are required to improvethe nutritional status in children with generalized epilepsy soas to optimize their growth and development.

ABSTRACT

Background: Iron requirements are increased in adolescent girls with growth and the onset of menarche and remain high in women until menopause. Methods: We conducted a study on two study groups of girls in age group 18-25 years belonging to different socioeconomic classes as per the Modified Kuppuswamy’s Scale to study the effect of the phases of menstrual cycle & socioeconomic class on the iron status indicators (Hb, Serum Iron, TIBC, MCV & TS%).Menstrual phases were defined and blood samples were drawn from all the girls in all the 3 phases (menstrual, follicular & luteal) and Hb, Serum iron & Total iron binding capacity were assessed on a semi-auto-analyzer & MCV was estimated using a fully automated CBC machine. Transferrin Saturation was derived as Serum Iron / TIBC × 100. Results: We found significant (p< 0.01) difference in iron status indicators in both our groups, the values of iron status indicators varied significantly according to the menstrual cycle, with values highest during the luteal phase and lowest during the menstrual phase. From our observations we can conclude that the nutritional status (assessed by the height, weight & BMI) and the iron status indicators both differ significantly in the two age-matched comparable socio-economic groups. Conclusion: socioeconomic class has a major determining role on an individual’s health. The effect of hormonal fluctuations during the menstrual cycle also has a part to play in the variation of iron status measures, which has to be considered while measuring them in a female during her reproductive years

ABSTRACT

Objectives: Transthoracic electrical bio-impedance (TEB) has been proposed as a non-invasive and continuous method of cardiac output (CO) measurement, but it still has not found wide usages in clinics. The present study measured CO, using a new instrument NICOMON, and compared it with Echocardiography (ECHO) in acute myocardial infarction (AMI) patients. Methods: In the present study 100 patients of AMI were assessed by both ECHO and NICOMON for cardiac output and ECHO is considered as a reference method for comparison. TEB CO was measured by passing an alternating current and measuring the bio-impedance across the thorax. End diastolic volume (EDV), End systolic volume (ESV) & Left ventricular outflow tract (LVOT) diameter, measured by ECHO were used to calculate CO. Various statistical methods like “t”-test & correlation coefficient (r) were used where found suitable. Results: Mean TEB-CO (4.03±1.11 l/min) was significantly higher (p<0.001) than mean ECHO-CO (3.80±1.28 l/min) with a mean difference of 0.25±1.02 l/min. Conclusions: NICOMON measures CO non-invasively but, it needs more elaborative studies on a larger sample to establish it as an alternative method of ECHO for cardiac output measurement on regular basis.

ABSTRACT

Impedance Cardiography (ICG) is a non invasive method useful for continuous monitoring of cardiac output but, it still has not found wide usage for measuring cardiac output in clinics and research. Most studies focused on comparing the cardiac output measured at rest with reference methods. In the present study we evaluated the validity of ICG against Doppler Echocardiography (DE) in measuring cardiac output changes that occur during static exercise. Cardiac output of 30 healthy males between 18-26 yrs of age was measured during supine rest, during and 5 min after completion of 3 minute static exercise by ICG and DE. The increase in cardiac output during exercise measured with ICG and DE does not differ significantly (1.04±0.72 L/min and 1.05±1.24 L/min respectively) and has significantly high correlation (r=0.76, P<0.001). The bias and limits of agreement are (–0.01±0.83) in acceptable limits. The pooled means of cardiac output measured by ICG and DE do not differ significantly and bears a significant correlation (r=0.812, P<0.001). The bias (d±s) calculated is 0.15±0.64 L/min. ICG could provide valid information regarding the relative changes in cardiac output.
