  • 简介:AbstractThe novel coronavirus disease 2019 (COVID-19) is the third coronavirus outbreak in the last two decades. Emerging and re-emerging infections like COVID-19 pose serious challenges of the paucity of information and lack of specific cure or vaccines. This leaves utilisation of existing scientific data on related viral infections and repurposing relevant aetiologic and supportive therapies as the best control approach while novel strategies are developed and trialled. Many promising antiviral agents including lopinavir, ritonavir, remdesivir, umifenovir, darunavir, and oseltamivir have been repurposed and are currently trialled for the care for COVID-19 patients. Adjunct therapies for the management of symptoms and to provide support especially in severe and critically ill patients have also been identified. This review provides an appraisal of the current evidence for the rational use of frontline therapeutics in the management of COVID-19. It also includes updates regarding COVID-19 immunotherapy and vaccine development.

  • 简介:AbstractBackground:The pandemic of the coronavirus disease 2019 (COVID-19) has caused substantial disruptions to health services in the low and middle-income countries with a high burden of other diseases, such as malaria in sub-Saharan Africa. The aim of this study is to assess the impact of COVID-19 pandemic on malaria transmission potential in malaria-endemic countries in Africa.Methods:We present a data-driven method to quantify the extent to which the COVID-19 pandemic, as well as various non-pharmaceutical interventions (NPIs), could lead to the change of malaria transmission potential in 2020. First, we adopt a particle Markov Chain Monte Carlo method to estimate epidemiological parameters in each country by fitting the time series of the cumulative number of reported COVID-19 cases. Then, we simulate the epidemic dynamics of COVID-19 under two groups of NPIs: (1) contact restriction and social distancing, and (2) early identification and isolation of cases. Based on the simulated epidemic curves, we quantify the impact of COVID-19 epidemic and NPIs on the distribution of insecticide-treated nets (ITNs). Finally, by treating the total number of ITNs available in each country in 2020, we evaluate the negative effects of COVID-19 pandemic on malaria transmission potential based on the notion of vectorial capacity.Results:We conduct case studies in four malaria-endemic countries, Ethiopia, Nigeria, Tanzania, and Zambia, in Africa. The epidemiological parameters (i.e., the basic reproduction number R0 and the duration of infection DI) of COVID-19 in each country are estimated as follows: Ethiopia (R0 = 1.57, DI = 5.32), Nigeria (R0 = 2.18, DI = 6.58), Tanzania (R0 = 2.47, DI = 6.01), and Zambia (R0 = 2.12, DI = 6.96). Based on the estimated epidemiological parameters, the epidemic curves simulated under various NPIs indicated that the earlier the interventions are implemented, the better the epidemic is controlled. Moreover, the effect of combined NPIs is better than contact restriction and social distancing only. By treating the total number of ITNs available in each country in 2020 as a baseline, our results show that even with stringent NPIs, malaria transmission potential will remain higher than expected in the second half of 2020.Conclusions:By quantifying the impact of various NPI response to the COVID-19 pandemic on malaria transmission potential, this study provides a way to jointly address the syndemic between COVID-19 and malaria in malariaendemic countries in Africa. The results suggest that the early intervention of COVID-19 can effectively reduce the scale of the epidemic and mitigate its impact on malaria transmission potential.

  • 简介:摘要:目的:本研究通过对ABCA3外显子10进行基因测序和分析,初步探讨ABCA3 exon10区域上是否有基因变异或多态性位点分布,探讨其与新生儿呼吸窘迫综合征(neonatal respiratory distress syndrome,NRDS)发病的相关性,从基因水平探讨NRDS的发病机制。方法:收集于2017年9月-2021年3月在海淀妇幼保健院新生儿重症监护病房住院的NRDS患儿26例作为病例组,同时间段、同群体中26例非NRDS新生儿作为对照组。分别提取两组基因组DNA,PCR扩增ABCA3 exon10,并将扩增产物进行直接测序,分析两组ABCA3 exon10 是否有变异或多态性位点存在。结果:在ABCA3 exon10 rs13332514(F353F)位点存在单个碱基点突变C>T,密码子由TTC变为TTT,第353编码位点氨基酸未发生改变。病例组和对照组均存在该位点点突变,其中NRDS组共有16例,变异率为30.2%,非NRDS组共有7例,变异率为13.2%,NRDS组显著高于非NRDS组(X2=4.498,P=0.034),差异具有统计学意义;结论: ABCA3外显子10区域上rs13332514 (F353F)位点存在单个碱基点突变C>T,该位点变异可能与新生儿发生NRDS有相关性,等位基因T可能是增加新生儿发生NRDS的易感因素之一。
