Whereas a large number of features are mentioned to connote the quality of medical research, no tool is available to comprehensively measure it objectively across different types of studies. Also, all the available tools are for reporting, and none includes quality of the inputs and the process of research. The present paper is aimed to initiate a discussion on the need to develop such a comprehensive scoring system (in the first place), to show that it is feasible, and to describe the process of developing a credible system.

An expert group comprising researchers, reviewers, and editors of medical journals extensively reviewed the literature on the quality of medical research and held detailed discussions to parse quality at all stages of medical research into specific domains and items that can be assigned scores on the pattern of quality-of-life score.

Besides identifying the domains of the quality of medical research, a comprehensive tool for scoring emerged that can be possibly used to objectively eviewed by the researchers and needs to be validated.
The association between hyperglycaemia at admission, diabetes mellitus (DM) status and mortality in hospitalized SARS-CoV-2 infected patients is not clear. The purpose of this study was to determine the relationship between DM, at-admission hyperglycaemia and 28 day mortality in patients admitted with moderate-severe SARS-CoV-2 infection requiring intensive care.

All consecutive moderate-to-severe patients with SARS-CoV-2 infection admitted to the intensive care units (ICUs) over six months were enrolled in this single-centre, retrospective study. The predicators for 28 day mortality were analysed from the independent variables including DM status and hyperglycaemia at-admission.

Four hundred and fifty two patients with SARS-CoV-2 were admitted to the ICU, with a mean age of 58.5±13.4 yr, 78.5 per cent being male, HbA
of 7.2 per cent (6.3-8.8) and 63.7 per cent having DM. Overall, 28 day mortality was 48.9 per cent. In univariate analysis, mortality in diabetes patients was comparable with non-diabetes (47.9 vs. 50.6%, P=0.58), while it was significantly higher in hyperglycaemic group (60.4 vs. 35.8%, P<0.001). In multivariate Cox regression analysis, after adjusting for age, sex and comorbidities, hyperglycaemia at-admission was an independent risk factor of mortality [hazard ratio (HR) 1.45, 95% confidence interval (CI) (1.06-1.99), P<0.05].

This study showed that the presence of hyperglycaemia at-admission in critically ill SARS-CoV-2 patients was an independent predictor of 28 day mortality. However, the findings may be susceptible to unmeasured confounding, and more research from prospective studies is required.

High mortality has been observed in the cancer population affected with COVID-19 during this pandemic. We undertook this study to determine the characteristics and outcomes of cancer patients with COVID-19 and assessed the factors predicting outcome.

Patients of all age groups with a proven history of malignancy and a recent diagnosis of SARS-CoV-2 infection based on nasal/nasopharyngeal reverse transcriptase (RT)-PCR tests were included. Demographic, clinical and laboratory variables were compared between survivors and non-survivors groups, with respect to observed mortality.

Between May 11 and August 10, 2020, 134 patients were included from the three centres and observed mortality was 17.1 per cent. The median age was 53 yr (interquartile range 39-61 yr) and thirty four patients (25%) were asymptomatic. Solid tumours accounted for 69.1 per cent and breast cancer was the most common tumour type (20%). One hundred and five patients (70.5%) had received chemotherapy within the past four weeks and 25 patients (19.3%) had neutropenia at presentation. On multivariate analysis, age [odds ratio (OR) 7.99 (95% confidence interval [CI] 1.18-54.00); P=0.033], haemoglobin [OR 6.28 (95% CI 1.07-37.04); P=0.042] neutrophil-lymphocyte ratio [OR 12.02 (95% CI 2.08-69.51); P=0.005] and baseline serum albumin [OR 18.52 (95% CI 2.80-122.27); P=0.002], were associated with higher mortality. Recent chemotherapy, haematological tumours type and baseline neutropenia did not affect the outcome.

Higher mortality in moderate and severe infections was associated with baseline organ dysfunction and elderly age. Significant proportion of patients were asymptomatic and might remain undetected.

The COVID-19 pandemic has caused significant global morbidity and mortality. As the vaccination was rolled out with prioritization on healthcare workers (HCWs), it was desirable to generate evidence on effectiveness of vaccine in prevailing real-life situation for policy planning. The objective of the study was to evaluate the safety, effectiveness and immunogenicity of COVID-19 vaccination among HCWs in a tertiary care hospital.

This prospective observational study was undertaken on the safety, immunogenicity and effectiveness of the ChAdOx1 nCoV- 19 coronavirus vaccine (Recombinant) during the national vaccine roll out in January-March 2021, in a tertiary care hospital, New Delhi, India.

The vaccine was found to be safe, with local pain, fever and headache as the most common adverse events of milder nature which generally lasted for two days. The adverse events following vaccination were lower in the second dose as compared to the first dose. The vaccine was immunogenic, with seropositivity, which wasgainst the COVID-19 disease (CTRI/2021/01/030582).
ChAdOx1 nCoV-19 coronavirus vaccine (Recombinant) was safe, immunogenic as well as showed effectiveness against the COVID-19 disease (CTRI/2021/01/030582).
Vaccination against COVID-19 induces spike protein-binding IgG antibodies, a robust correlate of protection against COVID-19. This study was undertaken to assess the humoral response after completion of both the doses of ChAdOx1 nCoV vaccine in healthcare workers (HCWs) at a tertiary care health centre in India.

A cross-sectional COVID-19 vaccine-induced antibody study was conducted among HCWs. IgG antibodies against spike protein were measured at least 28 days after the first dose and the second dose of vaccination in both SARS CoV-2 naïve and recovered HCWs. Mean and median antibody titre following each dose of vaccine and its association with age, gender, co-morbidities and factors such as exercise, stress and sleep deprivation were also explored.

Among the 200 vaccine recipients, 91.5 per cent showed seroconversion after the first dose and 99.5 per cent after the second dose. The mean titre after the second dose was significantly higher when compared to the first dose (12.68±4.17 vs. 9.83±6.3, P=0.0dOx1 nCov-19 vaccine after two doses elicited an excellent immune response. However, greater immunogenicity after the first dose was seen among those with previous COVID-19 infection, even surpassing the titre achieved by the second dose of vaccine in SARS CoV-2 naïve recipients. A fall in antibody titre after the second dose is a matter of concern and requires further studies.This retrospective analysis was done to ascertain the SARS-CoV-2-positivity rate in children (0-12 yr) with severe acute respiratory infection (SARI) and compare it to those without SARI to determine the need for running a dedicated SARI isolation facility for paediatric COVID-19 care. The case records of 8780 children (0-12 yr) admitted and/or tested for SARS-CoV-2 between June 2020 and May 2021 at a tertiary care centre in north India were analyzed. The overall SARS-CoV-2 reverse transcription (RT)-PCR positivity rate was 3.0 per cent (262/8780). There were 1155 (13.15%) children with SARI. Fifty of these 1155 (4.3%) children with SARI, as against 212 of the 7625 (2.8%) children without SARI, tested positive for COVID-19. The absolute difference in the positivity rate among SARI and non-SARI groups was only 1.54 per cent which translates to cohorting and isolating 65 children with SARI to pick up one extra SARS-CoV-2-positive child (compared to those without SARI). The positive predictive value of SARI as a screening test was 4.3 per cent. Our findings suggest that isolation of children with SARI as a transmission-prevention strategy for COVID-19 may not be required. This is particularly relevant in resource-limited settings.
Studying vaccine hesitancy is important for helping improve vaccine coverage against COVID-19. The objective of this study was to assess the prevalence and correlates of COVID-19 vaccine hesitancy in a rural community in India.

A cross-sectional study of all adults aged over 18 yr was undertaken during July-August 2021, in a village outside Bengaluru city in southern India.

In our study, 68.7 per cent of the eligible 297 adult population accepted vaccination immediately, another 9.4 per cent hesitated but accepted vaccination without delay, a further 10.4 per cent delayed their vaccination and the remaining 11.5 per cent refused vaccination. The prevalence (95% confidence interval) of vaccine hesitancy was 21.9±4.8 per cent. Full vaccination was higher among males (76%) compared to females (58%, P <0.001). Those who hesitated and delayed vaccination (converts) were more likely to be from a nuclear family, whereas those who refused the vaccine were from a joint/three-generation family. Those who refusividual- and population-level protection.
The COVID-19 pandemic had a distinct impact on scientific research and Ethics Committees (ECs). We conducted a mixed-methods investigation to understand the issues faced and solutions identified by ECs during this pandemic in India.

A quantitative online survey form (30 members) and qualitative in-depth interviews (10 members) from various ECs were conducted. Thematic content analysis for qualitative and proportion analysis for quantitative data was carried out.

During the online survey, an average difficulty score, which was measured using the Visual Analogue Scale, was 5.3 (SD 2.1). Pressure for expedited approvals was felt by EC members with a drastic increase in the number of submission of research projects. The scarcity of information on investigational products (IPs) and requisite consent process posed major hurdles. Ongoing non-COVID studies and post-graduate dissertations were badly hit due to the shift in attention towards COVID-related research. ZK53 Non-familiarity with virtual technology and lack of face-to-face interactions were highlighted as demerits. However, a few of the EC members welcomed newer methods, being time-saving, convenient and reducing travel hassles. Site monitoring and severe adverse event-related analyses were also negatively impacted upon. Solutions included the alternate methods of consenting (virtual, abbreviated), a detailed explanation of the protocol and IPs and benefits versus risk assessment.

Despite various challenges posed by the COVID-19 pandemic, the ECs in India steered well through the hurdles. Moreover, adapting a hybrid mode, technical training and updating guidelines were perceived as urgent by EC members.
