简介：AbstractCOVID-19 has been a global health concern since 2019 until date. Global concerted efforts to combat this pandemic has resulted in a number of vaccines distributed across the globe. Although the presence of these vaccines produced quick interventions, dynamic mutation in the causal virus and the continuous evolution of new stains that defy available vaccines has given rise to pertinent questions. The most recent emergence of a new COVID-19 virus variant (omicron), the rapid spread and overwhelming rate of morbidity and mortality has reopened these questions for debate. This commentary summarizes major view on these questions and concludes that multiple approach including social behavioural measures, vaccination and antiviral drug would speed up elimination process.

简介：AbstractSince its first description in 2013, robust evidence supporting the efficacy and safety of the endoscopic sleeve gastroplasty (ESG) has been on the rise. A large case series and meta-analysis report supported results up to 24 months, while some other studies already described 5-year data. If associated with pharmacotherapy, the ESG may help one to achieve weight loss similar to that of surgical sleeve gastrectomy. Though the results of the ongoing randomized trials on ESG are awaited, currently available data support the clinical use of the ESG, especially for patients who are refusing or unfit for bariatric surgery.

简介：AbstractA series of stringent non-pharmacological and pharmacological interventions were implemented to contain the pandemic but the pandemic continues. Moreover, vaccination breakthrough infection and reinfection in convalescent coronavirus disease 2019 (COVID-19) cases have been reported. Further, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants emerged with mutations in spike (S) gene, the target of most current vaccines. Importantly, the mutations exhibit a trend of immune escape from the vaccination. Herein the scientific question that if the vaccination drives genetic or antigenic drifts of SARS-CoV-2 remains elusive. We performed correlation analyses to uncover the impacts of wide vaccination on epidemiological characteristics of COVID-19. In addition, we investigated the evolutionary dynamics and genetic diversity of SARS-CoV-2 under immune pressure by utilizing the Bayesian phylodynamic inferences and the lineage entropy calculation respectively. We found that vaccination coverage was negatively related to the infections, severe cases, and deaths of COVID-19 respectively. With the increasing vaccination coverage, the lineage diversity of SARS-CoV-2 dampened, but the rapid mutation rates of the S gene were identified, and the vaccination could be one of the explanations for driving mutations in S gene. Moreover, new epidemics resurged in several countries with high vaccination coverage, questioning their current pandemic control strategies. Hence, integrated vaccination and non-pharmacological interventions are critical to control the pandemic. Furthermore, novel vaccine preparation should enhance its capabilities to curb both disease severity and infection possibility.
