Background COVID-19 vaccines were authorised for emergency use to mitigate the impact of the pandemic. This study evaluated the effect of prior vaccination with either Oxford Astra Zeneca’s Covishield TM or Bharath Biotech’s Covaxin® on mortality among symptomatic COVID-19 patients during the second wave of the pandemic in India. Methodology In this cohort study comprising of RT-PCR confirmed symptomatic COVID-19 patients presenting during April and May 2021, the effect of prior vaccination on mortality (primary outcome), need for hospitalization, oxygen therapy, non-invasive ventilation (NIV) and intensive care unit (ICU) admission were assessed and expressed as risk ratio (RR) with 95% confidence intervals (CI). Results The mean (SD) age of the cohort (n=4183) was 46.3 (15.5) years; 17.9% (748/4183) had received at least one dose of Covishield TM and 4.8% (201/4183) had received Covaxin®. Mortality was 0.2% (95% CI: -0.2% - 0.7%), 3.5% (1.9% - 5.2%), 6.2% (0.3% - 12%) and 12.9% (11.8% - 14.1%) among fully vaccinated (>2 weeks after two doses), partially vaccinated (>2 weeks after one dose or <2 weeks after two doses), indeterminate (<2 weeks after one dose) and unvaccinated patients respectively. The difference in mortality among unvaccinated vs. fully vaccinated was 12.7% (95% CI: 11.4% - 13.9%), unvaccinated vs. partially vaccinated was 9.4% (7.4% - 11.4%) and unvaccinated vs. indeterminate vaccinated was 6.8% (0.8% - 12.7%). On adjusted analysis, as compared to unvaccinated patients, at least one dose of vaccine reduced the need for hospitalization (RR: 0.40; 95% CI: 0.35 - 0.47), oxygen (0.33; 0.27 - 0.40), NIV (0.23; 0.17 - 0.32), ICU admission (0.18; 0.12 - 0.27) and mortality (0.18; 0.11 - 0.29). Conclusion Among symptomatic COVID-19 patients, prior vaccination with Covishield TM or Covaxin® impacted the severity of illness and reduced mortality during a period of widespread delta variant circulation. Full vaccination conferred greater protection than partial vaccination.

Background The COVID-19 pandemic compelled the Indian government to enforce a complete nationwide lockdown on 24th March 2020. Methods This retrospective study was done to analyse the profile of trauma patients presenting to the emergency department (ED) from January to August 2020. Data from 69 days of lockdown and 83 days of pre-lockdown periods were used to calculate the 30-day incidence rates. Results During the 7-month study period, 5220 patients presented to our ED with trauma; 2296 in the prelockdown phase (83 days), 1205 during the lockdown phase (69 days), and 1719 during the postlockdown phase (92 days). There was a significant decrease (36.7%) in the 30-day incidence rate of trauma victims presenting to the ED during the lockdown phase (525) compared with the prelockdown phase (830). The 30-day incidence of road traffic accidents (RTA), fall from height, fall on level ground and other trauma decreased by 53.2%, 26%, 23.2% and 12.9%, respectively, while assault cases increased by 8.3% during the lockdown period as compared with the prelockdown period. During the lockdown period, the 30-day incidence of trauma victims with a positive blood alcohol content decreased by 39.6% with a significant drop in the strict lockdown month of April 2020. Conclusions A significant reduction in the incidence rate of trauma victims, especially RTA and geriatric trauma was seen during the gruelling lockdown period of the COVID 19 pandemic.

We report a case of an 18-year-old girl diagnosed to have Moyamoya disease (MMD), who underwent bilateral encephalo-duro-arterio-myo-synangiosis. Literature search has clearly inferred that in comparison to an adult patient, children with MMD can have a good prognosis if early diagnosis and active surgical intervention are achieved. Evidence has demonstrated that active surgical management, including indirect bypass surgery, may improve the cerebral circulation on a relatively larger scale than direct bypass surgeries, which can only improve the cerebral circulation in the area of the vascular reconstruction.
