ABSTRACT
Since December 2019, severe acute respiratory syndrome coronavirus 2(SARS - CoV - 2) infections have raged globally for more than 2 years. China has always adopted scientific and effective prevention and control measures to achieved some success. However, with the continuous variation of SARS - CoV -2 cases and imported cases from abroad, the prevention and control work has become more difficult and complex. With the variation of the mutant strain, the number of cases in children changed, and some new special symptoms and complications were found, which proposed a new topic for the prevention and treatment of SARS - CoV - 2 infection in children in China. Based on the third edition, the present consensus according to the characteristics of the new strain, expounded the etiology, pathology, pathogenesis,and according to the clinical characteristics and experience of children's cases,and puts forward recommendaions on the diagnostic criteria,laboratory examination,treatment,prevention and control of children's cases for providing reference for further guidance of effective prevention and treatment of SARS - CoV - 2 infection in children in China.Copyright © 2022 Chinese Journal of Applied Clinical Pediatrics.

ABSTRACT
Introduction: We aimed to analyse the effect of coronavirus disease 2019 (COVID-19) vaccination on F-18-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) imaging findings in cancer patients. Methods: A total of 165 oncology patients who underwent FDG PET/CT between 1 May 2021 and 30 September 2021 after their first or second COVID-19 vaccination with were included in this retrospective study. The occurrence and pattern of FDG uptake at the injection site (usually deltoid), ipsilateral axillary and other regional lymph nodes, were measured. Results: Overall, the incidence of FDG-avid ipsilateral regional nodal uptake was 26.7% (44/165), with a median maximal standardised uptake value of 3.2 (range, 1.7-13.8). Vaccine-associated hypermetabolic lymphadenopathy (VAHL) was found in 11.4% (5/44) of the subjects beyond 6 weeks after vaccination. VAHL was more common in patients receiving BioNTech-Fosun mRNA vaccine (compared with patients receiving the Sinovac CoronaVac inactivated vaccine), and in women (p < 0.05). Conclusion: VAHL is common and can be observed beyond 6 weeks after vaccination. It was seen more frequently in women and in patients receiving the mRNA-based vaccine. Proper vaccination history documentation, locating the vaccination site contralateral to the primary cancer, and appropriate scheduling of FDG PET/CT are advisable for correct image interpretation.
ABSTRACT
Most countries have implemented lockdowns as the main non-pharmaceutical intervention in response to the global Covid-19 pandemic. Such actions have resulted in negative economic impacts on different sectors, which include manufacturing and processing industry. This concern has led to the need to develop post-lockdown “exit strategies” to mitigate the adverse socio-economic impacts. In this work, a systematic approach is developed to quantify the criticality of economic sectors based on a sector criticality index (SCI) and rank them based on their importance relative to the entire national economy. SCI is a weighted composite score based on five criteria which capture relevant dimensions in judging the importance of sectors: economic impact, connectivity, sector size, income multiplier, and employment. The input-output model is then used to evaluate the interaction amongst the economic sectors. The use of the proposed approach is illustrated with a case study focusing on evaluating the impact on oleo-chemical industries and associated agro-industrial sectors in Malaysia.
