ABSTRACT
BACKGROUND: Given the high incidence of asymptomatic or subclinical SARS-CoV-2 infection, reported cases likely underestimate the overall prevalence and infectivity of COVID-19. Serological test for IgG can provide a better measure of disease activity by identifying asymptomatic or subclinical infection. This study was conducted to estimate the seroprevalence of SARS-CoV-2 infection and to the determinants of SARS-CoV-2 infection in the hotspot area of COVID-19. METHOD: It was a community-based, cross-sectional study using multistage sampling with a sample size of 360. After informed consent, the demographic information, past history of SARI/ILI, contact, COVID-19 status were collected. The blood samples were taken from one family member for anti-SARS-CoV-2 IgG antibody by ELISA testing kit. RESULTS: Majority of the study subjects had no history of SARI (86%) or any contact with COVID-19 case (98%). Overall seroprevalence of anti-SARS-CoV-2 of IgG antibody was 40% (95% CI 35-45%), infection fatality rate (IFR) was 0.7%. Seroprevalence varied significantly depending on religious background; with Muslims (53%) seroprevalence compared to other religious groups. Seroprevalence of homemaker/unemployed (49%) and laborer (55%) was significantly higher compared to business (30%) and service occupation (21%). Subjects with overcrowding conditions and poor ventilation was significantly associated with higher seroprevalence with odds ratio of 2.5 and 2.3, respectively. CONCLUSION: The antibody testing detects a large number of asymptomatic cases or previously infected cases which would have been missed by clinical history. Thus, the number of undiagnosed cases was found significantly higher even with rigorous implementation of lockdown.
ABSTRACT
INTRODUCTION: Mobile technology is one of the latest extensions of technological innovations that can be integrated into medical education. With the aid of these devices, students learn faster outside the classroom by having quick access to the internet and easy retrieval of required health related learning resources to keep alongside of recent trend and development. In medicine practice one has to continuously update his/her medical knowledge and mobile learning will serve as a tool for self-directed learning. AIM: To explore the attitudes and perceptions of undergraduate students towards M-learning. MATERIALS AND METHODS: This educational research included 90 third year MBBS students having clinical posting under the Department of Community Medicine from tertiary healthcare institute in Nashik. Students learning approach was studied with the help of pre-validated questionnaire to know whether they have deep or surface approach to learning. M-learning group was formed on mobile social app to supplement conventional teaching-learning. One subject topic (Tuberculosis, Dengue fever/DHF, Hypertension and Diabetes Mellitus etc.) per week was allotted and after conventional teaching on first day of week the learning materials for the topic chosen for that week were uploaded on the group and students could download as well as share their ideas, learning resources, ask doubts and answer questions at least twice weekly through this mobile platform anytime, anywhere. At the end of three months students attitudes and perceptions towards M-learning were studied by pre-validated structured questionnaires. A five point Likert scale was used (5= strongly agree to 1= strongly disagree) for answering each item of all three questionnaires. The score of 60% (90 out of 150) and the score of 75% (30 out of 40) for each item was considered as the measure that indicates whether or not the student had a positive attitude and perceived the importance of M-learning respectively. Utilisation of M-learning was also studied. RESULTS: It was found that 47 (52.2%) students had deep learning approach, 10 (11.1%) students had surface learning approach. An 80% of students had positive attitude towards M-learning and 76.7% students had perceived the importance of M-learning. A 52.2% of students were actively involved in M-learning group for learning purpose. But 57.8% students did not download (at least twice weekly) the shared reference material, 38.9% students never read and/or replied to the questions asked and 60.0% students never asked any doubts/questions related to the discussion. CONCLUSION: Students had positive attitude and perceived the importance of M-learning. But when they were provided with the opportunity, they did not show appreciable M-learning utilization. This could be because, M-learning was not implemented by all departments; also it was not the part of student's regular assessment and probably a lesser study duration.
ABSTRACT
BACKGROUND: India's National Family Welfare Programme is dominated by sterilization, particularly tubectomy. Sterilization, being a terminal method of contraception, decides the final number of children for that couple. Many studies have shown the declining trend in the average number of living children at the time of sterilization over a short period of time. So this study was planned to do time series analysis of the average children at the time of terminal contraception, to do forecasting till 2020 for the same and to compare the rates of change in various subgroups of the population. MATERIALS AND METHODS: Data was preprocessed in MS Access 2007 by creating and running SQL queries. After testing stationarity of every series with augmented Dickey-Fuller test, time series analysis and forecasting was done using best-fit Box-Jenkins ARIMA (p, d, q) nonseasonal model. To compare the rates of change of average children in various subgroups, at sterilization, analysis of covariance (ANCOVA) was applied. RESULTS: Forecasting showed that the replacement level of 2.1 total fertility rate (TFR) will be achieved in 2018 for couples opting for sterilization. The same will be achieved in 2020, 2016, 2018, and 2019 for rural area, urban area, Hindu couples, and Buddhist couples, respectively. It will not be achieved till 2020 in Muslim couples. CONCLUSION: Every stratum of population showed the declining trend. The decline for male children and in rural area was significantly faster than the decline for female children and in urban area, respectively. The decline was not significantly different in Hindu, Muslim, and Buddhist couples.
ABSTRACT
Injury is a major public health problem in India. As very few studies are available from rural areas, hence the present study was carried out to study the epidemiology of injuries in the rural areas of Maharashtra. A cross-sectional study was carried out in Primary Health Centres (PHC) of a district in Maharashtra. 4790 subjects were studied using a two stage sampling technique. During last one year, 19.0% (95% CI: 17.7%-19.9%) had at least one injury. Majority of injuries (94.0%) were unintentional while assault and suicide related injuries were 37 (4.1%) and 10 (1.1%) respectively. Age, sex, education, occupation and socio-economic status were significantly associated with injuries.
