ABSTRACT

Visual reaction time is time required to response to visual stimuli. The present study was conducted to measure visual reaction time in 209 subjects, 50 table tennis (TT) players and 159 healthy controls. Methods: The visual reaction time was measured by the direct RT computerized software in healthy controls and table tennis players. Simple visual reaction time was measured. During the reaction time testing, visual stimuli were given for eighteen times and average reaction time was taken as the final reaction time. Results: The study shows that table tennis players had faster reaction time than healthy controls. On multivariate analysis, it was found that TT players had 74.121 sec (95% CI 98.8 and 49.4 sec) faster reaction time compared to non-TT players of same age and BMI. Also playing TT has a profound influence on visual reaction time than BMI. Conclusion: Our study concluded that persons involved in sports are having good reaction time as compared to controls. These results support the view that playing of table tennis is beneficial to eye-hand reaction time, improve the concentration and alertness

ABSTRACT

Background and objectives: The respiratory system changes with age and understanding these changes helps detect and prevent respiratory dysfunctions in the elderly. Pulmonary function, as measured by spirometry is an important predictor of morbidity and mortality of elderly persons. The aim of the present study was to see the effects of aging on pulmonary functions. Methods : The study included 150 subjects of different ages from 20 years and above. Subjects were divided in six groups depending on their age. (1) 20-29 yrs (2) 30-39 yrs (3) 40-49 yrs (4) 50-59 yrs (5) 60-69 yrs (6) 70 yrs and above. 25 subjects were included in each group. FVC , FEV1, FEV1 /FVC%, PEFR, FEF25%-75%, MVV were measured. Results: Comparing 20-29 yrs with 70 yrs and above show mean FVC (4.33 vs 1.68 litre, p<0.001) ,FEV1(3.91 vs 1.19 litre p<0.001), FEV1 /FVC%(90.30 vs 70.0 p<0.001), PEFR(9.81 vs 3.31 lit/sec p<0.001), FEF25%-75%(6.65 vs 1.89 lit/sec p<0.001), MVV(93.94 vs 55.96 lit/min p<0.001). Conclusion: Our study concluded that FVC, FEV1, FEV1/FVC, PEFR, FEF25- 75% and MVV decrease with age. It is probably a result of decreased strength of expiratory muscles, decreased chest wall compliance and increased tendency of airways to close during forced expiratory effort causing air trapping in the lungs.

ABSTRACT

Background: Hypertension is known to be risk factor for the development of proteinuria in patients with uncontrolled diabetes mellitus type2, leads to progression of end stage renal disease Aims & Objective: To study the effect of hypertension on diabetic nephropathy in type 2 diabetic patients. Material and Methods: We investigated, progression of diabetic nephropathy by measuring arterial blood pressure , serum creatinine and glomerular filtration rate(GFR) level in 60 (35 men and 25 women) type 2 uncontrolled diabetes mellitus patients on antihypertensive treatment. Results: The survey was done for 6 months during which 30 (group 1) -uncontrolled diabetes mellitus patients with normal blood pressure were compared with 30 (group 2) -Uncontrolled diabetes mellitus patients with hypertension who had mean systolic blood pressure (SBP) was 148.86 ± 5.12 mmHg. In group 2 the mean level of serum creatinine (1.71 ± 0.46 mg/dl) was significantly higher and mean GFR (54.57 ± 35.26 ml/min) was significantly lower than group 1 (P < 0.05). Conclusion: Uncontrolled hypertension leads to progression of diabetic nephropathy with decline in GFR earlier than normotensive uncontrolled diabetic patients.

ABSTRACT

Background: Diabetes is global endemic with rapidly increasing prevalence in both developing and developed countries. There is a high risk of cardiovascular diseases in people with type 2 diabetes, while Abnormal lipid profiles and lipoprotein oxidation (especially LDL-C) are more common in diabetics and are aggravated with poor glycaemic control. The aim of the present study is to assess the glycaemic control status by HbA1c estimation and to compare the lipid profile in type 2 diabetes patients with good glycaemic control (HbA1c≤8) & those with poor glycaemic control (HbA1c>8). Materials and methods: The present study was conducted on 100 type-2 diabetic males aged 40-60 years. Among them 48 patients having HbA1c level ≤8% were categorized as having good glycaemic control (group-1)and 52 patients with HbA1c >8% were categorized as having poor glycaemic control(group-2). Result: A significant increase in S.cholesterol(254.46±45.54), s.LDL(162.57±39.79), S.VLDL(45.98±14.69) and S.triglycerides (225. ±76.61) in group-2 pateints (P≤0.05) were noticed as compare to group-1 patients. Our findings suggest positive association between dyslipidemia and glycemic control on the basis of screening with the HbA1c level. Raised triglyceride and LDL levels are established risk factors for coronary artery diseases. Conclusion: The optimal care of diabetic patients should also include periodic screening for lipid abnormalities and periodic measurement of HbA1C for glycaemic control.

ABSTRACT

Stress is inevitable in today’s world however people are different in the way they cope with stress. This study investigated the variable response to stress by the 1ST M.B.B.S. students during their 1ST credit examination. Thirty three male students participated in the study. They were divided into 2 groups, Group I- having less than 6 hours sleep, Group II-having more than 6 hours sleep before exam. Pulse rate was significantly higher in both the groups pre- examination (88±8.4 vs.78±4.47/min and 83.26± 9.96 vs 75.26±9.21/ min) Pre examination Systolic (118±7.27 vs 110±7.37mmHg) as well as Diastolic Blood Pressure (77.89±5.47 vs 72.1±5.05 mmHg) was significantly higher in group II. However the same was not significantly different in group I. On comparing the two groups pre exam none of parameters were significantly different while post exam only systolic BP was significantly higher in group I. Marks obtained in 3 subjects by two groups were not significantly different. Students vary in their response to stress as reflected in the sleep hours, reading habits & cardiac responses. Students having an abnormal sympathetic nerve activity at rest & in response to stressor, may be more susceptible to hypertension in future. The students should be screened and those showing sustained BP response should be followed up periodically.
