Influencing factors associated with quality of life and depression among COVID-19 survivors during convalescence.

This study aims to investigate influencing factors of quality of life (QoL) and depression among COVID-19 survivors during convalescence. A cross-sectional study was conducted in November 2020 in Wuhan, China. Information on social support, physical activity, QoL and depressive symptoms were assessed using self-administered questionnaires. Multivariate linear regression and multivariate logistic regression were used to assess the risk factors of subdomains of QoL (physical component score (PCS) and mental component score (MCS)) and depression, respectively. A total of 151 COVID-19 survivors (68 males) aged 53.21 (SD: 12.70) years participated in the study. Multivariate linear regression showed that age (ß=-0.241), history of chronic disease (ß=-0.4.774), physical activity (ß = 2.47) and social support (ß = 0.147) were significantly associated with PCS, while having a spouse (ß = 9.571), monthly income (ß = 0.043) and social support (ß = 0.337) were significantly associated with MCS. Logistic regression suggested that participants aged 40-60 years (OR = 10.20, 95%CI: 1.41-73.82) or above 60 years (OR = 15.63, 95%CI: 1.87-131.00), with high school or above education (OR = 5.81, 95%CI: 1.24-27.20), with low/moderate physical activity (low, OR = 2.97, 95%CI: 1.14-7.77; moderate, OR = 3.42, 95%CI: 1.07-10.91) and low/medium social support (low, OR = 4.81, 95% CI: 2.02-11.43; medium, OR = 9.70, 95%CI: 1.17-80.10) were more likely to be depressed, while higher monthly income (≥3000 Yuan RMB/month) was associated with lower risk for depression (OR = 0.27, 95%CI: 0.09-0.82). These findings indicate COVID-19 survivors with older age, having chronic conditions, without a spouse, low monthly income, low level of physical activity and social support had significantly increased risks for poor QoL and depression, and more attention should be given to this population.

OBJECTIVES: To study the features of unintentional injury in children under the impact of coronavirus disease 2019 (COVID-19). METHODS: A retrospective analysis was performed on the medical data of 2 526 children with unintentional injury in Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from July 2019 to June 2022. The study period was divided into 5 stages: before the epidemic (July to December, 2019), the Wuhan epidemic period (January to April, 2020), the epidemic remission period in China (May 2020 to February 2022), the Shanghai epidemic period (March to May, 2022), and the epidemic remission period in Shanghai (June 2022). The incidences of unintentional injury in children at different time stages and different ages were compared. A questionnaire survey was conducted on 107 children of the 2 526 children to explore the features of unintentional injury. RESULTS: There were significant differences in gender composition, age, age distribution and proportion of many types of unintentional injuries among the five time stages (P<0.05). There was a reduction in the number of children who attended the emergency department due to unintentional injury during the Wuhan epidemic and the Shanghai epidemic. The proportion of children with trauma-related unintentional injuries in each stage reached more than 50%, and the proportion of children with trauma-related unintentional injuries reached 63.9% and 82.0%, respectively during the Wuhan epidemic and the Shanghai epidemic. Most children suffering from unintentional injury were mainly school-aged and preschool children (1 823 children, 72.17%). Compared with the same period of Shanghai epidemic in 2021, the age of children with unintentional injury was younger (median 7 years vs 11 years), and the proportion of children with trauma-related unintentional injuries increased (97% vs 69%) during the Shanghai epidemic (P<0.05). CONCLUSIONS: Under the COVID-19 epidemic, there is a reduction in the number of children with unintentional injury, while there is an increase in the proportion of children with trauma-related unintentional injuries. Unintentional injury is more common among school-aged and preschool children.

Safety and immunogenicity of SARS-CoV-2 vaccines in Chinese patients with cirrhosis: a prospective multicenter study.

BACKGROUND: Data on safety and immunogenicity of coronavirus disease 2019 (COVID-19) vaccination in patients with compensated (C-cirrhosis) and decompensated cirrhosis (D-cirrhosis) are limited. METHODS: In this prospective multicenter study, adult participants with C-cirrhosis and D-cirrhosis were enrolled and received two doses of inactivated whole-virion COVID-19 vaccines. Adverse events were recorded within 14 days after any dose of vaccination, and serum samples of enrolled patients were collected and tested for SARS-CoV-2 neutralizing antibodies at least 14 days after the second dose. Risk factors for negative neutralizing antibody were analyzed. RESULTS: In total, 553 patients were enrolled from 15 centers in China, including 388 and 165 patients with C-cirrhosis and D-cirrhosis. The vaccines were well tolerated, most adverse reactions were mild and transient, and injection site pain (23/388 [5.9%] vs 9/165 [5.5%]) and fatigue (5/388 [1.3%] vs 3/165 [1.8%]) were the most frequently local and systemic adverse events in both the C-cirrhosis and D-cirrhosis groups. Overall, 4.4% (16/363) and 0.3% (1/363) of patients were reported Grades 2 and 3 alanine aminotransferase (ALT) elevations (defined as ALT > 2 upper limit of normal [ULN] but ≤ 5 ULN, and ALT > 5 ULN, respectively). The positive rates of COVID-19 neutralizing antibodies were 71.6% (278/388) and 66.1% (109/165) in C-cirrhosis and D-cirrhosis groups. Notably, Child-Pugh score of B and C levels was an independent risk factor of negative neutralizing antibody. CONCLUSIONS: Inactivated COVID-19 vaccinations are safe with acceptable immunogenicity in cirrhotic patients, and Child-Pugh score of B and C levels is associated with hyporesponsive to COVID-19 vaccination.

Key Risks and Development Strategies for China's High-End Medical Equipment Innovations.

OBJECTIVE: Sufficient amounts of basic medical materials and high-end medical equipment are required for epidemics. This study aims to investigate and determine the key risks and main factors influencing China's high-end medical equipment innovations using a SWOT (Strengths, Weaknesses, Opportunities, Threats) matrix. Then, on the basis of findings and relevant literature concerning the development of China's high-end medical equipment in recent years, especially during the COVID-19 period, we put forward strategies for the development of and innovations in high-end medical equipment for China, based on an analytic network process ANP-SWOT model. METHODS: In this study, a comprehensive ANP-SWOT analysis model was selected to examine the current state of development of the high-end medical equipment innovation industry in China. First, a SWOT model was used to comprehensively analyze the internal and external factors influencing the development of the industry. Then, an ANP network structure was designed to accurately reflect the relationships among the influencing factors. Subsequently, weights for the influencing factors were determined according to the importance of the factors, and alternative choices for China's strategy for high-end medical equipment innovation were presented. RESULTS: The results revealed that the essential features of the best strategy for the innovation and development of China's high-end medical equipment industry were as follows: first, speeding up the construction and improvement of a technological innovation system that is enterprise-dominated, market-oriented, and involves joint industry-university research; second, a greater focus on increasing the financial support for research and development and industrialization; and third, strong government support through taxes, medical insurance, promotion of talent, and appropriate land usage. CONCLUSION: Strong governmental support through taxes, medical insurance, promotion of talent, and land usage is required to ensure rapid development of the high-end medical equipment industry in China.
