Long-span cable-supported bridge is one of crucial transportation infrastructures. Structural health monitoring (SHM) system that is used to assess structural service conditions and detect early damage has drawn a growing attention in engineering structural society. It provides a real-time monitoring of various structural changes under operational and extreme conditions. Yangluo Bridge over Yangtze River in Wuhan city of China is a 1280 m central span suspension bridge with an orthotropic steel box girder. Taking the SHM system of Yangluo Yangtze River Bridge as an example, this paper presents an implementation of SHM system on the bridge in terms of sensor layout, data acquisition strategy, data transmission, data processing, and abnormal alarm framework. With such an SHM system, the typical monitoring results are demonstrated such as operational environments, loadings, structural deformation, strains, dynamic properties, and structural responses. The SHM system of Yangluo Yangtze River Bridge is continuously gathering data and monitoring structural behavior. It is anticipated that it will provide either scientific or technological supports to the service comfort and safety of the bridge. [ABSTRACT FROM AUTHOR]

Objective: This study aims to investigate perinatal depression in women who gave birth during the COVID-19 pandemic in Wuhan, and to evaluate the effect of the pandemic on perinatal depression prevalence. Methods: A cross-sectional investigation was conducted into women hospitalized for delivery in Hubei Maternity and Child Healthcare Hospital from December 31, 2019 to March 22, 2020, a period which encompasses the entire time frame of the COVID-19 pandemic in Wuhan. The Edinburgh Postnatal Depression Scale (EPDS) was adopted to evaluate perinatal depression status. A Chi-square test and logistic regression model were utilized for data analysis. Results: A total of 2,883 participants were included, 33.71% of whom were found to suffer from depressive symptoms. In detail, 27.02%, 5.24%, and 1.46% were designated as having mild, moderate, and severe depressive symptoms, respectively. The perinatal depression prevalence increased as the COVID-19 pandemic worsened. Compared to the period from December 31, 2019 to January 12, 2020, perinatal depression risk significantly decreased within the 3 weeks of March 2–22, 2020 (1st week: OR = 0.39, 95% CI: 0.20, 0.78; 2nd week: OR = 0.35, 95% CI: 0.17, 0.73; and 3rd week: OR = 0.48, 95% CI: 0.25, 0.94); and the postnatal depression risk significantly rose within the four weeks of January 27-February 23, 2020 (1st week: OR = 1.78, 95% CI: 1.18, 2.68; 2nd week: OR = 2.03, 95% CI: 1.35, 3.04; 3rd week: OR = 1.48, 95% CI: 1.02, 2.14; and 4th week: OR = 1.73, 95% CI: 1.20, 2.48). Conclusion: The dynamic change of perinatal depression was associated with the progression of the COVID-19 pandemic among new mothers who were exposed to the pandemic. An elevated risk of postnatal depression was also observed during the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

• The analyze and measure the change trend of land use and ecosystem service value in Wuhan during the past 31 years. • Simulation of land use change in Wuhan in 2040 under 4 scenarios. • The ecological protection scenario is the optimal ideal scenario. • The future development trend of Wuhan City will be progressive from the central to the southeast. Simulation of changes in ecosystem service value (ESV) caused by land use change in Wuhan under multiple scenarios is of great significance for ensuring urban ecological security and enhancing regional ecosystem service values. The city of Wuhan was selected as the study area, and the changes in land use and ESV in Wuhan over the past 31 years were analyzed and calculated based on five-phase remote sensing images and statistical yearbooks for 1990, 1998, 2006, 2014 and 2021. On this basis, the CA-Markov model and the multi objective planning (MOP) model were used to simulate the land use change in the study area in 2040 under four scenarios (natural development scenario, cultivated land protection scenario, ecological protection scenario and urban development scenario), and the total ESV was estimated under each scenario. The total value of ecosystem services was estimated under each scenario, and grid tools were applied to visualize the spatial distribution and degree of aggregation of ecosystem services. The results show that: (1) The most obvious feature of land use change in Wuhan from 1990 to 2021 is the sharp reduction in arable land area and the rapid expansion of build-up land area. Over the past 31 years, the arable land area decreased by 78322.4 hm2, and the build-up land area increased by 52559.28 hm2. (2) From 1990 to 2021, Wuhan's total ESV at the five timepoints (1990, 1998, 2006, 2014, 2021) was 74.554 billion yuan, 71.512 billion yuan, 69.632 billion yuan, 73.433 billion yuan and 68.548 billion yuan, respectively. Overall, there has been a downward trend in volatility. (3) Under the four scenarios, the ESV in 2040 is projected to be 72.777 billion yuan, 70.969 billion yuan, 74.097 billion yuan or 70.620 billion yuan, respectively. Among them, the ecological protection scenario is the optimal simulation choice. (4) The cold and hot spots of ESV show an aggregated distribution over a large area, with the hot spots mainly concentrated in the central and southeastern parts of Wuhan and the cold spots mainly located in the northeastern and northwestern portions of Wuhan. Simulating the future land use change trends in Wuhan and exploring the responses of ecosystem service values under various scenarios are conducive to the construction of a new pattern of urban land space development and protection and can provide a scientific basis and a reference for decision-making for comprehensively promoting the sustainable development of Wuhan and other metropolitan areas in China in the future.

The epidemiologic and clinical characteristics of heart transplant (HTx) recipients during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) epidemic remains unclear. We studied the characteristics of HTx recipients from December 20, 2019, to February 25, 2020, in an effort to understand their risk and outcomes. All accessible HTx recipients were included in this single-center retrospective study. We collected information on the recipients using a web-based questionnaire as well as the hospital database. We followed 87 HTx recipients (72.4% were men, and the average age was 51 years). A total of 79 recipients resided in Hubei, and 57 recipients had a Wuhan-related history of travel or contact. Most took precautionary measures while in contact with suspicious crowds, and 96.6% of the families and communities undertook prevention and quarantine procedures. Four upper airway infections were reported, and 3 of them tested negative for SARS-CoV-2 (the fourth recovered and was not tested). All cases were mild and successfully recovered after proper treatment. Laboratory results of 47 HTx cases within the last 2 months were extracted. Of these, 21.3% of recipients had pre-existing lymphopenia, and 87.2% of recipients had a therapeutic concentration of tacrolimus (5–12 ng/ml). Liver and kidney insufficiency was seen in 5 and 6 recipients, respectively. HTx recipients who practiced appropriate prevention measures had a low rate of infection with SARS-CoV-2 and transition to the associated disease COVID-19. These early data will require confirmation as the pandemic establishes around the world. [ABSTRACT FROM AUTHOR]
