ABSTRACT
Aim: Digital device usage, especially during the pandemic, has catapulted into a new age problem, the computer vision syndrome. This study aimed to quantify the prevalence and determinants of digital eye strain (DES). Subject and Methods: A total of 345 university students in India were surveyed in June-July 2022, by a validated tool, the Computer Vision Syndrome Questionnaire (CVS-Q) © in this cross-sectional study. According to American Optometric Association, digital eye strain and computer vision syndrome are synonyms. Non-parametric tests of medians were used to compare the median DES scores, Chi square test to compare categorical variables, and binary logistic regression to find the determinants of DES. Results: The average age of the study participants was 21.0 ± 2.2 years, ranging between 18-26 years with 52.8% females and 47.2% males. The prevalence of DES was 45.5% (CI 95% = 40.2%-50.8%). Any existing eye disease (p-value = 0.000, OR = 0.41, 95% CI = 0.26-0.65), average daily screen time (p-value = 0.001, OR = 1.61, 95% CI = 1.22-2.13) and using gadgets in the dark (p-value = 0.000, OR = 0.37, 95% CI = 0.23-0.61) were significant determinants of the same. Conclusion: Framing guidelines limiting the hours allotted for online classes for university students are imperative, with promotion of ergonomic practices for digital device usage such as blue light filters and night mode on devices.
ABSTRACT
As the coronavirus disease 2019 (COVID-19) pandemic perseverates on, more insight into the multidisciplinary manifestations of COVID-19 is being brought to the forefront. Musculoskeletal presentations range from mild creatinine kinase elevation and myalgias to severe rhabdomyolysis. We present a case of a patient who presented with symmetric myositis of bilateral gastrocnemius muscles secondary group.
ABSTRACT
Coronavirus disease 2019 (COVID-19) has been shown to impact the cardiovascular system by causing congestive heart failure, arrhythmias, myocarditis, acute coronary syndrome (ACS), or nonischemic cardiomyopathy. The infection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) triggers the overproduction of proinflammatory cytokines, generating systemic inflammation and a procoagulant state that can lead to cardiovascular morbidity and mortality. Symptomatology may not be discrete with presentation of chest pain, dyspnea, and fatigue, so careful consideration should be applied to cardiovascular complications. Serial troponin dosage as well as EKG changes serve as viable prognosis markers. Prompt dissolution of the thrombi will minimize the extent of the myocardial injury.
