ABSTRACT

Introduction: Coronavirus Disease-2019 (COVID-19) has affected healthcare access to population around the world. India also had its own set of problems for patients with disruption of healthcare services during the pandemic. This also brought in unique challenges for ophthalmologists who adapted to new challenges to provide quality care to the patients including those reporting for cataract surgery. Aim: To find out cataract surgery trends and demographic variables during lockdown and unlocking periods of COVID-19 pandemic. Materials and Methods: This cross-sectional hospital-based study was conducted at Ophthalmology department of a tertiary care centre in eastern India, from January 2020 to March 2022. Trends of cataract surgery including numbers, demographic factors, visual acuity at presentation, difference during first and second lock and unlock periods etc were compared during various lock and unlock period over more than two years. Results: A total of 3,843 patients were planned for surgery and 3,594 patients underwent cataract surgery. A total of 218 patients reported being positive for COVID-19 preoperatively and voluntarily dropped out from surgery. A total of 24 patients were found to be positive during preoperative Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) workup and were excluded from surgery. Seven patients didn't report for the surgery. A total of 59 patients reported febrile illness during one month postoperative period. There was dip in cataract surgery during lockdown periods (from 178.33 every month in pre COVID-19 period to near zero during first lockdown period) but recovery was much faster during second unlock period compared to first unlock period. Conclusion: The study concludes that there was drastic decrease in number of patients undergoing cataract surgery during COVID-19 pandemic. Predominantly young, male patients who had advanced morphology of cataracts with poor visual acuity accessed healthcare set-up for cataract surgery during initial lock and unlock period. Similar trend was seen during second lock and unlock period with rapid recovery of numbers and demography of cataract surgery patients to pre-COVID-19 levels.

ABSTRACT

This is the second part of a two-part series article. Recently, we have been in the middle of a difficult time due to the Covid-19 pandemic. Pandemics or global epidemics are not new to humankind;they have occurred many times in history. The discourse of epidemiology describes mainly the causal factors which need to be mitigated to prevent or combat the effects of epidemics. In epidemiology, we are not concerned for a person, but rather every individual globally, to make life healthier for all. In this article, we will discuss the basics of epidemiological practice that scientists have used for centuries to prevent epidemics with great results. Overall, we plan for better global health aided by epidemiology. © 2023, Indian Academy of Sciences.

ABSTRACT

In this paper, there are four distinct models utilized for the retrieval of CSPM from the Sentinel 2A/2B satellite imageries by using cloud computing techniques. In this study, a comparative analysis of different CSPM models was carried out at three different sites (Haridwar, Varanasi, and Hooghly). The study reveals that there are significant changes in CSPM in the Ganges in three different periods such as pre, during, and post-COVID. Noteworthy, fewer anthropogenic activities have generated important transformations in aquatic environments during the COVID. © 2023 IEEE.

ABSTRACT

Background: Lockdown during COVID-19 led to teachers and children shifting to online classes, using visual display terminals (VDTs) for education, resulting in increased screen time. The present study was done to assess and understand the nature and magnitude of the problem and to suggest preventive or remedial measures. Methods: A questionnaire-based cross-sectional study was conducted. The questionnaire was prepared for an online survey (using Google Forms) and circulated among school children belonging to different schools across India using multiple groups on social media. Results: A total of 3327 participants from 46 schools across India participated in the survey. We found a marked rise in cumulative screen time for both teachers and students before and during the lockdown. There was a threefold increase in the number of participants with a cumulative screen time 6 h or more compared to the pre-COVID era. Teachers (older participants) had worse symptom scores than students. Larger screens, like televisions, were better VDTs compared to smartphones, tablets, or laptops. Conclusions: School administrators and policymakers should pay due attention to institutionalizing the guidelines about class duration, appropriate screens, and stipulating break duration during online classes, which will continue to remain the predominant mode of education for teachers and students alike, at least in the near future.

ABSTRACT

In contrast to existing research that used ground-based observations, in this research we used space-borne observations to study global air quality change during COVID-19 pandemic in 20 countries. It is observed that during lockdown, PM2.5 has reduced in the most of the countries by 56% in 2020 compared to the previous year, whereas, Ghana and Russia show an increasing pattern. It is observed that NO2 has dropped in most of the countries by 3% to 31%, whereas UK and South Africa exhibit an increasing trend. Although spatial variability, low spatial resolution, and mixed pixel impurity may obscure the observation, but the study suggests a space-borne approach can be useful for investigating change in air quality to provide a general insight during COVID-19 pandemic. Our space-borne observations show an improvement in air quality by considerable drop in contaminants in the air in most of the countries except Russia and Ghana during COVID lockdown. © 2020 IEEE.

ABSTRACT

Since the end of January, 2020 when the first case of coronavirus disease 2019 (Covid-19) was detected in Thrissur, Kerala and rapidly spread throughout India over a short span of time, there has been an ardent need of data on the clinical presentations of the affected patients.This study has been done by extracting data from 95 patients with laboratory-confirmed Covid-19 admitted in different hospitals of Assam, Chhattisgarh & West Bengal from 1st May to 15th May,2020.The median age of the patients was 44 years;62.1% of the patients were male.The most common symptoms were fever (69.47%) followed by cough(50.52%). Diarrhoea was less common (7.36%). Among the other atypical manifestations, anosmia was found in 3 patients & 2 patients developed cerebrovascular accident (CVA) during hospital stay. 24 patients had associated comorbidities (like hypertension, diabetes, hypothyroidism etc.). Our findings suggest that patients with Covid 19 may often present without fever and some patients may present with atypical features as well.

ABSTRACT

The coronavirus disease 2019 (COVID-19) has created a substantial burden on healthcare services worldwide. Since its first detection in 30th January, it has rapidly spread throughout India. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection results in clusters of severe acute respiratory illness leading to intensive care unit (ICU) admission and considerable mortality. So, there has been an ardent need of data on the frequency of comorbidities in COVID-19 & to assess whether their presence is associated with increased ICU admission. We analysed data from 496 patients with laboratory-confirmed Covid-19 admitted in tertiary care centers of three states of India from 15th to 30th May, 2020. The mean age was 49.7 years & 41.13% of the patients were female. Hypertension (21.97%) was the most frequent comorbidity followed by diabetes (12.90%) & cardiovascular disease (8.87%). 39.92% of the study population had at least one comorbidity. Patients with comorbidities had higher ICU admission than those without comorbidity (35.35% vs. 20.47%). Associated comorbidity was more frequent among ICU patients in comparison to non-ICU patients (53.43% vs. 35.07%). Our study findings suggest that presence of comorbidity is associated with higher ICU admission thereby indicating more severe disease.
