ABSTRACT
Medical education is witnessing changes across the globe to produce more competent and responsive medical graduates to meet patients’ growing needs. Medical educators are aspiring for more objective and relevant assessment methods for the evaluation of medical graduates. Objective structured clinical examination (OSCE) introduced in the year 1975 for clinical evaluation has gone through many changes over the past 45 years and matured over time. The article describes the challenges of OSCE as a tool in medical assessment from students’ and organizers’ perspectives. We have also suggested a feasible solution to address the challenges while conducting OSCE to assess medical students.
ABSTRACT
BACKGROUND Dietary salt intake is an important modifiable risk factor for cardiovascular diseases. Estimation of 24-hour salt intake using morning urine samples needs to be validated in the Indian context. We examined the performance of INTERSALT, Tanaka and Kawasaki equations for the estimation of 24-hour urinary sodium from morning fasting urine (MFU) samples. METHODS We enrolled 486 adults aged 18–69 years from four regions of India with equal rural/urban and sex representation to provide 24-hour urine samples. The next day, a MFU sample was obtained. Based on the volume and sodium content of the 24-hour urine sample, 24-hour sodium excretion (reference method) was calculated. Sodium levels in the MFU samples were measured along with other parameters required, and the above equations were used to estimate 24-hour urinary sodium levels. Intraclass correlation coefficient (ICC) was used to assess the degree of agreement between the estimates from the reference method and the three equations. Bland–Altman (BA) plots were used to identify systematic bias and limits of agreement. A difference of 1 g of salt (0.39 g of sodium) between the mean salt intake by 24-hour urine and as estimated by equations was considered acceptable. RESULTS A total of 346 participants provided both the samples. The mean (SD) daily salt intake estimated by the 24-hour urine sample method was 9.9 (5.8) g. ICC was low for all the three equations: highest for Kawasaki (0.16; 95% CI 0.05–0.26) and least for Tanaka (0.12; 0.02–0.22). Only Tanaka equation provided estimates within 1 g of measured 24-hour salt intake (–0.36 g). BA plots showed that as the mean values increased, all the three equations provided lower estimates of salt intake. CONCLUSION Tanaka equation provided acceptable values of 24-hour salt intake at the population level. However, poor performance of all the equations highlights the need to understand the reasons and develop better methods for the measurement of sodium intake at the population level.
ABSTRACT
For centuries, the handling of childbirth and childcare was considered the domain of midwives and mothers. The second half of the 20th century witnessed a change in thinking. The role of the state in improving the health of people came to the forefront. In the opening years of the 21st century, the millennium development goals placed maternal and child health at the core of the struggle against poverty and inequality, as a human rights issue. With a booming economy and an improved standard of living, no mother should die in the course of the normal process of giving birth. However, more than 500,000 mothers are still dying each year, mostly of avoidable causes
ABSTRACT
BACKGROUND: Dental caries remains the most important dental health problem in developing countries. In India the prevalence of dental caries is reported to be about 50-60%. Most of the Indian studies have been carried out in school children and very few in adults. This study aimed to estimate the prevalence of dental caries in the adult population (aged 35-44 years) and in the elderly (60 years and above) in an urban resettlement colony in New Delhi. METHODOLOGY: A community-based cross-sectional study was carried out in Dakshinpuri, New Delhi, from January to February 2007. A local adaptation of the WHO questionnaire was used. Oral examination was done and dentition status was recorded by trained investigators and according to the standard procedures. RESULTS: A total of 452 participants were enrolled in the study. The prevalence of dental caries in the 35-44 years age-group was 82.4% and it was 91.9% in those > or =60 years. The DMF index was 5.7 +/- 4.7 in the 35-44 years age-group and 13.8 +/- 9.6 in the > or =60 years age-group. Of the participants, 27.9% were currently using tobacco. A statistically significant association was found between tobacco consumption and dental caries ( P = 0.026). The awareness about good and bad dental practices was found to be low among the study participants. One-fifth of the individuals with dental problems relied on home remedies. CONCLUSION: The prevalence of dental caries among adults is high in this population. There is a need to generate awareness about oral health and the prevention of dental caries and to institute measures for the provision of dental care services at the primary level.
