Aim and Objectives: The present study assessed the perceived barriers as well as the preferences of the students toward the mode of education in the current scenario. Material and Methods: The study investigators developed a self-administered questionnaire using Google Forms (R) (Google LLC, Mountain View, CA) and were E-mailed to their respective E-mail ids and were informed telephonically about the survey. This survey was done among the BDS students of public health-care sector dental colleges in Delhi and the final data included 440 BDS dental students. Chi-square test was used to assess the association of the various factors among BDS students. Results: Higher response was obtained for Classroom Teaching for the 1st year students (65.6%) and Online Teaching for final year students (37.3%). The preference for online teaching over classroom teaching and understanding for the subject with your online classes was significantly better among final-year students (61.3%). The most common barrier experienced by the students was Network issue/poor range (52.5%) followed by understanding (17.0%) and excessive number of classes/Too long classes (10.2%). Conclusion: The present study showed that the 1st year dental students who just passed from the school had difficulty adapting to the Education via communication media. While the final year students were in a better position for adapting to the new system of learning.

Background: An elevated incidence of invasive pulmonary aspergillosis (IPA) in patients with COVID-19 without traditional risk factors for IPA has been recently reported around the world. This co-infection has been described in patients requiring treatment in an intensive care unit. The risk factors for its development are still unclear. Methods: We conducted a nested case-control study using the COVID-19 registry of the ARMII study group, based in the Centro Médico ABC, a private hospital in Mexico City. We included all patients that required admission to the intensive care unit (ICU) from March 12 to June 15, 2020, and excluded patients without serum galactomannan measurements or bronchial secretion cultures. We used the modified definition of IPA proposed by Schauwvlieghe et al for IPA in influenza patients. The control group was formed by patients with ruled-out IPA (negative galactomannan and secretion cultures). We compared both groups to identify risk factors for IPA using the chi-squared test or the Mann-Whitney U test as applicable. Results: Out of a total 239 patients, 54 met the inclusion criteria. We identified 13 patients with IPA (24.07%) that met the definition of IPA (2 with positive cultures and 11 with positive galactomannan) and 41 without IPA. Only three patients with IPA had important comorbidities (COPD, chronic kidney disease, and HIV). Patients with IPA tended to have a higher median age (64.6 vs 53.59, p=0.075) and a higher serum glucose at their arrival (145 vs 119, p=0.028). All patients with IPA presented to the hospital with ARDS (100% vs 72.5%, p=0.034), but ultimately did not have a higher requirement for mechanical ventilation (100% vs 82.93%, p=0.110). There were no statistical significant differences in use of Tocilizumab, use of glucocorticoids, mortality (23.07% vs 17.50%, p=0.563) or length of stay. Conclusion: It has been previously described that patients with acute respiratory disease syndrome triggered by viral infection, like the influenza virus, are prone to invasive aspergillosis even in the absence of underlying immunodeficiency. The use of antifungals to prevent aspergillosis in COVID-19 patients should be assessed because of the gravity presented in the patients with this co-infection.
