Advanced fibrosis determines the prognosis of nonalcoholic fatty liver disease(NAFLD);therefore,accurate risk-prediction for advanced fibrosis is fundamental in the management of NAFLD(1).Targeted screening for advanced fibrosis in high-risk populations,such as those with type 2 diabetes,obesity with metabolic complications,a family history of cirrhosis,or significant alcohol use is recommended for implementing early intervention to prevent future adverse hepatic outcomes of NAFLD(2,3).Non-invasive tests including fibrosis-4 index(FIB-4)and liver stiffness measurement(LSM)are recommended to identify individuals at a higher risk of liver-related events(1,2).In addition to clinical classifications,such as FIB-4;genetic information provides further stratification for liver-related outcomes(4).

Dear editor,Severe acute respiratory syndrome coronavirus2(SARS-CoV-2)infection can lead to severe outcomes in patients with cancer[1].It has been reported that patients with lung cancers disproportionately manifest severe COVID-19 with a high rate of hospitalization and death[2].Notably,the SARS-CoV-2 Spike(S)protein can induce hyper-inflammation in both epithelial cells and macrophages through toll-like receptor(TLR)1/TLR2 or TLR2/6-dependent nuclear factor-kappaB(NF-κB)path-way[3].However,molecular and cellular evidence on whether the SARS-CoV-2 virus affects the severity of lung cancer patients through TLR1/2 or TLR2/6 signaling remains unclear.
