The discipline of anaesthesiology in China has undergone historical changes and development during the past century. However, nationwide comprehensive data on the current status of each hospital department providing anaesthesia care has been lacking since the discipline was first established in China. This information is essential for effective regulation of healthcare policies by both the professional associations and the government health ministry. Therefore, a nationwide survey was set up in 2018 to investigate the current status of Chinese anaesthesiology. This paper reports the findings of the survey. We performed a cross-sectional nationwide census survey of the current status of each hospital department providing anaesthesia care in 31 provinces across the Chinese mainland. The content of the survey included general information of the department, the hospital level and scale, the volume of the anaesthesiology department, the characteristics of anaesthesiologists, and the caseload of the anaesthesiology departments. Face-to-face interviews were performed by trained interviewers. The Chinese Anaesthesiology Department Tracking Database (CADTD) was established during the survey. Data quality control was undertaken by the investigation committee throughout the survey process. The nationwide census survey was completed by 11,432 hospital departments providing anaesthesia care throughout mainland China from June 1, 2018 to June 30, 2019. Among the 11,432 departments, 4591 (40•16%) belonged to specialised hospitals, while 6841 (59•84%) were affiliated to general hospitals. The proportion of independent anaesthesiology departments was 45•15% in mainland China. There was a total of 92,726 anaesthesiologists, or 6•7 per 100,000 of the population. Regions with better economic conditions had more anaesthesiologists per 100,000 of the population. From 2015 to 2017, the workload of anaesthesiologists has increased by 10%. The discipline of anaesthesiology in China has entered a rapid development phase. However, the current status of anaesthesiology is not well defined, which makes it difficult to meet the needs of the increasing Chinese healthcare demand. The evidence from this survey offers valuable information for policy makers and anaesthesiology associations to monitor the development of the discipline and regulate healthcare policies effectively.

Background: Coronavirus Disease 2019 (COVID-19) is currently a global public health threat. Outside of China, Italy is one of the most suffering countries with the COVID-19 epidemic. It is important to predict the epidemics trend of COVID-19 epidemic in Italy to help develop public health strategies. Methods: We used time-series data of COVID-19 from Jan 22,2020 to Mar 16,2020. An infectious disease dynamic extended susceptible-infected-removed (eSIR) model, which covers the effects of different intervention measures in dissimilar periods, was applied to estimate the epidemic trend in Italy. The basic reproductive number was estimated using Markov Chain Monte Carlo methods and presented using the resulting posterior mean and 95% credible interval (CI). Hunan, with similar total number of populations in Italy, was used as a comparative item. Results: In the eSIR model, we estimated that the basic reproductive number for COVID-19 was respectively 4.10 (95% CI: 2.15–6.77) in Italy and 3.15(95% CI: 1.71–5.21) in Hunan. There would be totally 30 086 infected cases (95%CI:7920-81 869) under the current country blockade and the endpoint would be Apr 25 (95%CI: Mar 30 to Aug 07) in Italy. If the country blockade is imposed 5 day later, the total number of infected cases would expand the infection scale 1.50 times. Conclusion: Italy’s current strict measures can efficaciously prevent the further spread of COVID-19 and should be maintained. Necessary strict public health measures be implemented as soon as possible in other European countries with a high number of COVID-19 cases. The most effective strategy needs to be confirmed in further studies.

Background: As the focal point of epidemic prevention and control, the mental health of COVID-19 patients cannot be ignored. Online Mindfulness-Based Stress Reduction (MBSR) allows for the provision of conveniently accessible, effective and low-cost interventions on a large scale. We aim to evaluate the effectiveness of an online MBSR intervention in alleviating anxiety and depression among asymptomatic/mild patients limited by COVID-19-related restrictions. Methods: Fifty-eight patients treated in Sanya Fangcang hospital were randomly allocated to either to the experimental group (n = 29) following daily, for 5 days, an online-based mindfulness intervention or to the control group (n = 29). Patients from both groups underwent online questionnaires including assessment of anxiety and depression status at pre- and post-tests using Self-rating Anxiety Scale and Self-Rating Depression Scale. Results: After the online-based MBSR program, the anxiety and depression scores of the patients in the MBSR group decreased significantly in comparison to the scores of those in the control group (respectively η² = 0.175, η² = 0.215, p < 0.001). And the proportion of severe anxiety and depression patients in the MBSR group decreased to 0% which lower than the control group, and the proportion of light anxiety and depression patients was significantly more than that in the control group after the MBSR intervention. Conclusion: The online-based MBSR intervention appears to be an effective way of alleviating anxiety and depression symptoms among COVID-19 patients with associated quarantine in Fangcang hospital. Given the seriousness of mental health threat that could be posed by this ongoing pandemic, our study provides a new idea and method for cost-effective and time-efficient interventions in the future of epidemic prevention and control.

Background: Although high blood pressure (BP) is a risk factor for carotid plaque, its long-term prognostic value might be underestimated due to its confounding interactions with BMI, age, and gender. Therefore, we conducted a 7-year prospective cohort study to evaluate the prognostic value of BP for the incidence of carotid plaque.Methods: The subjects enrolled in 2011 were free of carotid plaque at baseline and were followed up in 2018. Multivariate Cox proportional-hazards models were used to evaluate the association between BP and carotid plaque incidence.Results: During the follow-up study, the incidence of carotid plaque was 36.5%. The significant positive linear trend showed that subjects with higher BP levels at baseline were more likely to develop carotid plaques at the end. Especially in the female subpopulation, after confounders being adjusted, the carotid plaque was associated with higher BP (adjusted HR 1.52, 95% CI 1.02–2.26), pulse pressure (PP) (adjusted HR 1.15, 95% CI 0.76–1.75), and mean arterial pressure (MAP) (adjusted HR 1.44, 95% CI 1.00–2.08). The adjusted HRs of hypertension, PP, and MAP (HR 27.71, 95% CI 2.27–338.64; HR 14.47, 95% CI 1.53–137.18; HR 9.97, 95% CI 1.29–77.28) were significantly higher after the potential antagonistic interactions between BP categorical indicators and age being adjusted, respectively.Conclusion: High BP indicators might be associated with higher HRs of carotid plaque after adjusting interactions between BP indicators and BMI, age, and gender, which suggests that the incidence of carotid plaque in female adults with high BP indicators might increase significantly with the increase of age.

Objective: To explore the preferred test to screen for pulmonary arteriovenous malformations (PAVMs) and to predict the probability of interventional embolization.Methods: We performed a retrospective observational study evaluating patients with idiopathic PAVMs from 2009 to 2019. After clinical evaluation, a total of 105 patients were studied, including 71 patients with positive digital subtraction pulmonary angiography (DSPA) findings and 34 with negative DSPA findings. The following patient data were assessed: blood test, chest radiograph, transthoracic contrast echocardiography (TTCE), and DSPA findings.Results: The majority of patients with idiopathic PAVMs were female (66.2% with positive DSPA findings). We found a good κ-coefficient of 0.77 with strong consistency for inter observer agreement concerning the pulmonary right-to-left shunt (RLS) grade on TTCE, which was superior to conventional chest radiographs. The positive predictive value (PPV) of the radiographic features for PAVMs on DSPA was 0.83 (95% CI 0.64–1.0) and 0.44 for the possibility of embolization (95% CI 0.19–0.70). The PPV of the shunt grade of PAVMs on DSPA was 0.14 (95% CI 0.01–0.29) for grade 1, 0.74 (95% CI 0.60–0.88) for grade 2, and 0.97 (95% CI 0.92–1.0) for grade 3. The PPVs of pulmonary shunt grades 2 and 3 on TTCE for the possibility of embolization for PAVMs were 0.21 (95% CI, 0.05–0.36) and 0.87 (95% CI, 0.79–0.99), respectively.Conclusion: TTCE is the preferred screening test for PAVMs. The pulmonary RLS grade on TTCE not only identifies the likelihood of PAVMs but also predicts the probability for embolization.
