Item Clinical validation of aneroid sphygmomanometer.(2012-07) Saxena, Yogesh; Saxena, Vartika; Gupta, RaniRecent concerns about the mercury toxicity and its ill effects on the environment and health has led to widespread use of aneroid manometers. Present study was conducted to analyse whether this change would lead to any systematic shift in measured blood pressure or consistency of blood pressure measurement in clinical setting. The clinical accuracy of the Welch Allyn aneroid sphygmomanometer model 7670-04 was studied against the mercury sphygmomanometer on 83 volunteers from Dehradun. Two blood pressure reading of each study subject was recorded with pretested instruments (aneroid and mercury sphygmomanometer). Data analysis showed the difference of means between the reading of two devices against mean of the observer reading for both systolic (-3.62±4.88) and diastolic (-2.36±3.77) blood pressure were not statistically different. The corresponding values of the SBP and DBP from both the instruments showed significant correlation. Regression analysis of mercury versus aneroid showed regression line (Y = 9.52 + 0.95X for SBP, Y = 0.36 + 0.96X for DBP) significantly different from line of equality (P<0.001). The study has demonstrated that the aneroid device (model: 7670-04) achieved grade B performance according to the British Hypertensive Society criteria.Item Effect of gender on correlation of anaemia with body mass index in medical students.(2011-10) Saxena, Yogesh; Shrivastava, Abha; Saxena, Vartika: Nutritional anemia exists globally and cuts across all the sections of the population. Adolescent being formative years in life are more susceptible to nutritional anemia. Considerable changes in growth pattern, lifestyle, dietary habits & behavior are likely to influence the hemoglobin levels among male and females of high income group. Study was done to assess the level of anemia among medical students and it’s relation to Body mass index (BMI) among medical students. 200 healthy medical students at the Himalayan Institute of Medical Sciences belonging to both the sexes were taken in the study. Following consent anthropometry was conducted using standard protocol. Body Mass Index of >/= 18.5 kg/m2 is used to define undernutrition. Hemoglobin was estimated in gram %. Statistical analyses was done using mean .Standard deviation, Student’s t test, and was studied for effect of gender on correlation of anemia with BMI. 8% of the students of MBBS were found to be anemic (Hb <12 g%) with none of the boys having hemoglobin <12 g% .15.5% under nutrition was observed in the medical students with (25.75%) of girls having a BMI of <18.5 kg/m2. A negative association of hemoglobin was found with nutritional status (BMI) (r = –0.59; P = 0.24) in over weight and obese females students. Nutritional anemia and under nutrition exist among female medical students who are literate, and have free access to the nutritive diet in a good healthy environment.Item Evaluation of dynamic function tests in normal obese individuals.(2008-10) Saxena, Yogesh; Saxena, Vartika; Dvivedi, Jyoti; Sharma, R KThe study was undertaken to assess the dynamic pulmonary function tests in obese and non obese young adults of Gharwal (Uttrakhand, India) of 20–40 years age group, randomly selected form the employees of Himalayan institute of medical sciences, attendants of the patients at the hospital and also from the nearby community at Jolly grant, Dehradun. The volunteers representing mixed socioeconomic group were categorized into obese cases and non-obese controls as per the standard criteria for Body mass index (BMI). Dynamic pulmonary function tests were carried out with all the standard protocols. Statistical analysis comprised student’s “t” test and linear correlation analysis. The result indicated a significantly lower value of (FVC) forced vital capacity (2.89±0.29) and (FEV1) Forced expiratory volume in 1st sec (2.59±0.25) in obese females. The FVC and FEV1 in the females correlated negatively to the BMI (r = –0.376, P<0.05 and r = –0.359 and P<0.05) and were significant. Dynamic pulmonary function values in males showed a negative correlation but were not statistically significant. This concludes that obesity per se has less effect on the dynamic function tests in obese young adults except in females, but obese individuals presenting with greater morbidity may be more susceptible to altered dynamic pulmonary function test in this age group.Item Predictive Value of Frailty Index in Comparison to Traditional Markers of Sepsis in Predicting Mortality among Elderly Admitted in Tertiary Care Hospital(Association of Physicians of India, 2022-09) Murlidharan, A; Dhar, M; Pathania, M; Agarwal, Mayank; Sethi, Prativa P; Saxena, Vartika; Bhat, Nowneet KIntroduction: The frailty index’s potential as a prognostic marker of sepsis is so far been untapped. Here we studied the predictive value of frailty index in the elderly with sepsis. Methods: This prospective cohort study was conducted in a tertiary level hospital in North India. The duration of the study was 18 months starting from January 2020 to July 2021. The frailty index was calculated along with traditional markers of sepsis such as sequential organ failure assessment (SOFA), quick sequential organ failure assessment (qSOFA), and systemic inflammatory response syndrome (SIRS) within 24 hours of admission in elderly patients suspected to have sepsis. The area under the receiver operating characteristic (AUROC) of frailty index, SOFA, qSOFA, and SIRS was compared for in-hospital and 3-month mortality. Results: There was no significant difference between the performance of the frailty index and SOFA (DeLong’s test p = 0.242) in predicting in-hospital mortality, but there was a statistical difference between the AUROC of SOFA score (AUC = 0.548) and frailty in predicting 3-month mortality (DeLong’s test p ?0.001). Conclusion: The frailty index had greater sensitivity and negative predictive value among the other scores in predicting in-hospital mortality, whereas SOFA had higher specificity in predicting in-hospital mortality. The frailty index was superior to SOFA and the other prognostic markers of sepsis in predicting 3-month mortality.Item A study on substance abuse among school going male adolescents of Doiwala Block, District Dehradun.(2010-10) Saxena, Vartika; Saxena, Yogesh; Kishore, Gaurav; Kumar, PratapAdolescent boys are recognized as a vulnerable group to substance abuse. The present study has the objective to study the biosocial profile and habit pattern of substance abusers. The study was conducted on 511 male adolescents, students of 10 th to 12 th class from the four intermediate schools of the Doiwala block of Dehradun district. 46.9% students accepted substance abuse. In 75.5% cases, friends were providing the substances. 80.2% substance abusers expressed their desire to quit the habit. The study is indicative of need for developing a supportive environment involving both parents and teachers so that adolescent can decide and sustain with the right choices for healthy life.
