Ambient air pollutants exposures may lead to aggravated Metabolic Dysfunction-Associated Fatty Liver Disease (MAFLD). However, there is still a scarcity of empirical studies that have rigorously estimated this association, especially in regions where pollution severe. To fill the literature gap, we conducted cross-sectional study involving 2711,207 adults living five southern Xinjiang Uyghur Autonomous Region 2021. Using Space-Time Extra-Trees model, assessed four-year (2017–2020) average...

<abstract> <p>The novel coronavirus disease 2019 (COVID-19) infection broke out in December Wuhan, and rapidly overspread 31 provinces mainland China on January 2020. In the face of increasing number daily confirmed infected cases, it has become a common concern worthy pondering when will appear turning points, what is final size would be ultimately controlled. Based current control measures, we proposed dynamical transmission model with contact trace quarantine predicted peak...

<abstract><p>This paper elucidates that the AIDS/HIV incidence rate differences exist among different population and regions, especially old college students. Due to effect of age, AIDS peak in males aged 20–35 years 50 both Chongqing Shenzhen, increasing spread was higher than females under period effect. In local over 40, below whole age groups are predicted increase sharply future six years, while females, rates 40-year-old were as well. The homosexually transmitted patients...
