ABSTRACT
BACKGROUND: The ongoing pandemic of coronavirus disease 2019 (COVID-19) has negatively impacted respiratory health worldwide. The severity of the disease varies considerably, and patients may present with bronchitis, pneumonia, and acute respiratory distress syndrome. This study aims to quantify the parameters of the pulmonary function test (PFT) with regard to the severity of COVID-19 and understand the pattern of PFT in reference to the status of selected morbidities and body mass index. MATERIALS AND METHODS: This is a hospital-based, comparative, cross-sectional study. A total of 255 COVID-19 survivors underwent clinical assessment, a PFT, and a 6-minute walk test. Participants were divided into mild, moderate, and severe disease groups. The parameters were compared between these groups. The PFT and 6-minute walk tests were conducted using an NDD Digital computerized spirometer (NDD Meditechnik AG., Switzerland) and a fingertip pulse oximeter (Hasely Inc., India), respectively. RESULTS: All PFT parameters showed significant differential distribution among the severity groups (p<0.001) except for forced expiratory volume in 1 s/ forced vital capacity (FEV1/FVC) and forced expiratory flow (FEF) during 25%-75% expiration and peak expiratory flow (PEF). Among severe category participants forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and FEV1/FVC, were significantly reduced as compared to mild and moderate. Severity was significantly affected by age >50 years. Severe category participants were seen in 31% of normal, 58% of pre-obese, and 53% of obese participants; however, this difference was insignificant. A significant reduction in SPO2 on the 6-minute walk test was observed in severely sick participants. CONCLUSIONS: COVID-19 is associated with a mixed pattern of spirometry. Poor prognosis is associated with older age, obesity, and multimorbidity.

ABSTRACT
BACKGROUND: With the emergence of COVID, we are forced to use e-learning in form of arranging online classes for students. Medical educators all over the world are conducting online classes for students. This study aimed to evaluate the perception of online learning among MBBS students and teachers through a questionnaire-based survey. MATERIALS AND METHODS: A cross-sectional study was done in the AIIMS, Bhopal. The study was based on questionnaire (online Google form) response received from 43 number of faculty and 156 number of students. STATISTICAL ANALYSIS USED: Chi-square test and unpaired t-test were used for statistical analysis using statistical software Systac 13.2. RESULTS: Handling software, technical issues, and lack of face-to-face interaction were more significant problems in students compared to faculty. The desire for the social site which causes disturbances in learning was a significant problem in the students compared to faculty. Giving and taking assessment problem was reported by 60% and 63.8% of faculty and students, respectively (P = 0.67). Both groups preferred the Google Classroom platform (P = 0.16). Students (65.3%) preferred audiovisual recording, while faculty (72%) preferred PowerPoint with narration. PowerPoint presentation without narration was the least preferred (10.8%). Both groups stressed the importance of training (P = 0.17) and infrastructure development (P = 0.85). Students, as well as faculty, strongly discouraged e-learning for practical/clinical teaching. CONCLUSIONS: Students, as well as faculty, have mixed reactions toward e-learning. Most importantly affected in the present scenario is practical/clinical teaching and assessment. Every attempt needs to be done to strengthen infrastructure and impart training to students and faculty.
