RESUMO
Introduction Since the emergence of the coronavirus disease 2019 (COVID-19) virus at the beginning of 2020, the world has gone through various waves of pandemics. The health care workers (HCWs) or the COVID warriors as they were termed were the first line of defense against the virus. They were armed with personal protective equipment and prophylactic doses of the COVID-19 vaccine. Despite these precautions, some of the HCWs still contracted the disease and a few others succumbed to it. The objective of this study was to estimate the prevalence of COVID-19 infections and vaccine breakthrough infections (BTIs) in HCWs after receiving the COVID-19 vaccine during the second wave of the pandemic. Methods This was a cross-sectional, hospital-based study conducted over a period of four months from September 2021 to December 2021 on HCWs aged 18 years and above working at the COVID-19-designated tertiary care government hospital in Sikkim. A structured coded questionnaire with no patient identifiers was used to gather details on demographics, vaccination history, breakthrough infection, and other social details. HCWs who had received at least one dose of the COVID-19 vaccine at the time of initiation of the study and were >18 years of age were included in this study. Results A total of 678 HCWs were screened, out of which 229 (33%) participants tested positive for COVID-19 and the rest of the participants (455; 67%) tested negative. COVID-19 infections and vaccine BTIs (COVID-19 infection >14 days after the second vaccination) were recorded and 137 (20%) respondents had a post-vaccination COVID-19 infection out of which 115 (18.5%) were BTI. The majority of the participants were females and of the age group of 26-35 years. The correlation of COVID-19 infections with the dose gap between vaccination, gender, age, profession, department, area posted during COVID duty, cycles of duty performed, hospitalization due to infection, influenza vaccination, and comorbidity was analyzed. Conclusion COVID-19 vaccines are disease-modifying and they decrease the severity of BTIs in HCWs. Pandemics and outbreaks cannot be predicted; therefore, it becomes very important to have healthy frontline workers who are constantly exposed to infectious agents. Monitoring of health and surveillance of infectious diseases among the HCWs should be encouraged.
RESUMO
This retrospective study was conducted to describe clinical and investigational findings and to determine the effect of thiamine treatment on mortality in patients admitted with acute non-infectious encephalopathy to a hospital in Sikkim between October 2019 and March 2021. Amongst 37 included patients the median age was 4 mo (IQR 3-5), 62.2% were males, 75% were exclusively breastfed infants, 67.6% and 89.2% patients had ophthalmologic and respiratory abnormalities respectively. Multisystem involvement was common. Bilateral basal ganglia involvement was noted in 75% of neuroimaging. Biochemical thiamine deficiency was confirmed in one infant. None of the 11 patients who received thiamine died whereas 20 among 26 patients who did not receive thiamine died [case fatality rate (CFR) 76.9%]. Thiamine treatment was significantly associated with reduced odds of mortality (aOR 0.046, 95% CI 0.0024-0.86, p 0.039). In patients with acute non-infectious encephalopathy and bilateral basal ganglia involvement thiamine use was associated with decreased mortality.
RESUMO
Rabies, a zoonotic viral encephalitis, continues to be a serious public health problem in India and several other countries in Asia and Africa. Survival is rarely reported in rabies, which is considered to be almost universally fatal. We report the clinical and radiological findings of eight patients with laboratory-confirmed rabies who survived the illness. With the exception of one patient who recovered with mild sequelae, all survivors had poor functional outcomes. The reported survival from rabies in recent years may reflect an increased awareness of the disease and greater access to better critical care facilities in rabies-endemic countries. Nonetheless, there is an urgent need to focus on preventive strategies to reduce the burden of this dreadful disease in rabies-endemic countries.
