Progresses on genetic susceptibility of COVID-19.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection causes a broad clinical spectrum of coronavirus disease 2019 (COVID-19). Genetic factors might influence susceptibility to the SARS-CoV-2 infection or disease severity. Genome-wide association studies (GWASs) have identified multiple susceptible genes related to COVID-19 phenotypes, providing the scientific basis for the COVID-19 prevention and treatment.

Development and evaluation of short-form version of the Constitution in Chinese Medicine Questionnaire: study a new and best brief instrument of Chinese medicine for health management.

Background: More efficient instruments for body constitution identification are needed for clinical practice. We aimed to develop the short-form version of the Constitution in Chinese Medicine Questionnaire (CCMQ) and evaluate for health management.

Methods: First, the short forms were developed through expert survey, classical test theory (CTT), and modern item response (IRT) based on the CCMQ.
