RESUMO
BackgroundThe initial outbreak of COVID-19 caused by SARS-CoV-2 in China in 2019 has been severely tested in other countries worldwide. We aimed to describe the spatial distribution of the COVID-19 pandemic worldwide and assess the effects of various socio-ecological factors on COVID-19 risk. MethodsWe collected COVID-19 pandemic infection data and social-ecological data of 178 countries/regions worldwide from three database. We used spatial econometrics method to assess the global and local correlation of COVID-19 risk indicators for COVID-19. To estimate the adjusted incidence rate ratio (IRR), we modelled negative binomial regression analysis with spatial information and socio-ecological factors. FindingsThe study indicated that 37, 29 and 39 countries/regions were strongly opposite from the IR, CMR and DCI index "spatial autocorrelation hypothesis", respectively. The IRs were significantly positively associated with GDP per capita, the use of at least basic sanitation services and social insurance program coverage, and were significantly negatively associated with the proportion of the population spending more than 25% of household consumption or income on out-of-pocket health care expenses and the poverty headcount ratio at the national poverty lines. The CMR was significantly positively associated with urban populations, GDP per capita and current health expenditure, and was significantly negatively associated with the number of hospital beds, number of nurses and midwives, and poverty headcount ratio at the national poverty lines. The DCI was significantly positively associated with urban populations, population density and researchers in R&D, and was significantly negatively associated with the number of hospital beds, number of nurses and midwives and poverty headcount ratio at the national poverty lines. We also found that climatic factors were not significantly associated with COVID-19 risk. ConclusionCountries/regions should pay more attention to controlling population flow, improving diagnosis and treatment capacity, and improving public welfare policies.
RESUMO
With the continuous development of bioinformatics technology and precision medicine, genetic mechanism investigations of genetic diseases including cleft lip and palate (CLP) have been getting more and more attention. Researchers have focused on the coding sequence of the genome and successfully found many CLP causative mutations, but there still remain some unsolved questions. In recent years, researchers′ vision has gradually shifted to non-protein coding region of the genome. This article reviews several coding sequence mutations, non-protein coding variants and their genetic mechanisms discovered in CLP researches.
