Risk perception and gratitude mediate the negative relationship between COVID-19 management satisfaction and public anxiety.

In this study, we explored whether satisfaction with government management, perception of risk, and gratitude influenced public anxiety during the COVID-19 pandemic in China. Using a cross-sectional, anonymous and confidential online survey, a nationwide sample of Chinese adults (N = 876) was targeted between March 25-March 30, 2020, a period in which newly confirmed cases significantly declined in China. The anxiety level was decreased as compared to that assessed during the peak period. Multiple parallel mediation modeling demonstrated that risk perception and gratitude partially mediated the relationship between satisfaction with government management and public anxiety. Increasing satisfaction and gratitude, as well as reducing risk perception contribute to the public's mental health. The results may shed light on the positive factors for psychological well-being during the COVID-19 pandemic and may aid potential strategies for the policy maker, the public, and the clinic to regulate negative emotions or future emerging infectious diseases.

Modified lung ultrasound scoring system to evaluate the feasibility of pregnant women with COVID-19 pneumonia.

OBJECTIVE: To investigate whether physicians with short-term training can use a modified lung ultrasound scoring system for coronavirus disease 2019 (COVID-19) pneumonia to assess lung damage in pregnant women. METHODS: Sixteen consecutively hospitalized third-trimester pregnant women with pregnancy-induced hypertension, preeclampsia, rheumatoid arthritis or connective tissue disease were selected as the study subjects for the simulation of COVID-19 pneumonia. Two physicians (imaging and internal medicine) without ultrasonic experience performed lung examinations on pregnant women after six days of lung ultrasound training, and their consistency with examinations by the expert was assessed. In addition, 54 healthy third-trimester pregnant women and 54 healthy nonpregnant women of the same age who were continuously treated in the outpatient clinic of this hospital were selected for comparisons of abnormalities on lung ultrasound. RESULTS: (1) Third trimester pregnant women with pregnancy-induced hypertension, preeclampsia, rheumatoid arthritis or connective tissue disease had the same lung ultrasound patterns as those associated with COVID-19 pneumonia. (2) There was no statistically significant difference between the scores of the two trained doctors and the expert when the modified ultrasound scoring system was used (p > .05). (3) The evaluations of the two trained doctors and the expert showed good consistency (kappa value = 0.833-0.957). (4) The incidence of abnormal ultrasound manifestations of the pleura and lung parenchyma was higher among healthy third-trimester pregnant women than among healthy women of the same age (p < .001). CONCLUSIONS: After receiving short-term training, imaging and internal medicine physicians can use the modified lung ultrasound scoring system to evaluate pregnant women's pulmonary damage, but caution is needed to avoid false-positive results among pregnant women with suspected COVID-19 pneumonia.
