Impact of overweight and obesity on ventilatory function among male medical students

To correlate the respiratory function among normal weight [BMI > 18.5 - 24.9 Kg/m[2]], overweight [BMI > 25 - 29.9 Kg/m[2]] and obese [BMI > 30 Kg/m[2]] male medical students who did not have evidence of obstructive or restrictive airway disease or other underlying diseases affecting their respiratory system. The other objective was to assess the correlation of respiratory function St body mass index [BMI]. Cross sectional controlled study was conducted among 113 eligible male medical students at college of medicine, King Saud University Riyadh, Kingdom of Saudi Arabia during August 2009 - July 2010. Body mass index was used to assess the obesity and forced expiratory volume in one second [FEV1] and forced vital capacity [FVC] were used to assess respiratory function. One way ANOVA was used to find the difference between BMI groups and bivariate correlation analysis was done to find out the strength of the relationship among BMI and respiratory function parameters. FEV1, FVC and FEV1/FVC ratio were linearly and mildly inversely related with BMI in overweight [r = -0.338, -0.291, -0.311 respectively] and obese [r = -0.375, -0.349, -0.040 respectively]. In normal weight subjects, FEV1 and FVC were mildly positively correlated [r = 0.136 and 0.219 respectively] and FEV1/FVC ratio was negatively correlated [r = -0.166] with BMI. Overweight and obesity are associated with pulmonary dysfunction among young male population

Validation of datascope accutorr plus [trade mark sign] using British hypertension society [BHS] and association for the advancement of medical instrumentation [AAMI] protocol guidelines

To assure the accuracy and reliability of blood pressure measurement by non-invasive blood pressure monitor using Datascope Accutorr Plus[trade mark sign] [Paramus, NJ,USA] against mercury manometer, among adult male participants. Eighty participants from a family physician's office at a teaching hospital were recruited. One hundred and sixty measurements of blood pressure were performed according to BHS technique protocol. Descriptive analysis was done according to the AAMI and BHS protocol guidelines. The limits of agreement between the device and the standard were plotted using the method of Bland and Altman plot. The mean difference +/- SD between the Datascope Acutorr Plus[trade mark sign] and observer was 2.7 +/- 5.2 mm Hg and 1.5 +/- 3.26 mm Hg for systolic and diastolic blood pressure, respectively. Datascope Acutorr Plus [trade mark sign] obtained A/A grading for both systolic and diastolic blood pressure. Datascope Accutorr Plus [trade mark sign] [Paramus, NJ, USA] satisfies BHS and AAMI validation protocols for both systolic and diastolic BP and may be recommended for everyday use for BP monitoring at home and in clinical use for adult population

Comparison between electronic BP apparatus [dynamap/datascope] versus standard mercury sphygmometer

To assess the accuracy of blood pressure measurement in adult population by Datascope/Dynamap versus Standard Mercury Sphygmometer, in a family physician's office. A cross sectional study was conducted in June 2008 at a university based teaching hospital in the Kingdom of Saudi Arabia, Eighty adult male subjects were recruited from a family physician's office. Blood pressure was taken from each participant by primary investigator by two different monitors i.e. sphygmometer and Datascope/dynamap. Highly significant different observed in systolic as well as diastolic blood pressure measurement by Datascope vs. mercury sphygmometer [P value less than 0.0001]. Highly significant different was seen in systolic blood pressure measurement by Datascope. Mercury Sphygmometer and Palpatory methods [P value less than 0.0001]. Significant different also was seen in pulse rate, checked by manually versus Datascope [P value 0.0008]. There was highly significant different between time taken to check blood pressure by Datascope versus Mercury Sphygmometer [P value less than 0.0001]. This study concluded that the electronic blood pressure monitor [Datascope/Dynamap] is not as good and accurate as universally accepted Mercury Sphygmometer for measurement of blood pressure in adult male population
