Online Homework Intelligent Platform Based on Self-Regulated Learning (SRL): Essential for Sustainable Development of Online Higher Education

Online higher education has become a steadily more popular way of learning for university students in the post-pandemic era. It has been emphasized that active learning and interactive communication are key factors in achieving effective performance in online learning. However, due to the lack of learning motivation of students and the lack of feedback data in online learning, there are numerous problems, such as the weak self-discipline of students, unsatisfactory learning experience, a high plagiarism rate of homework, and the low utilization of online teaching resources. In this study, an online homework intelligent platform implemented by information technology (IT) was proposed. It was based on the pedagogical self-regulated learning (SRL) strategy as a theoretical foundation, and information technology as a driver. Through setting online homework assignments, a sustainable means of promoting the four components of the SRL strategy, i.e., self-disciplinary control, independent thinking, reflective learning, and interest development, can be provided to university students. Therefore, this study explained the '4A';functions in the platform and analysed the details of their implementation and value, such as assistance in locating resources, assignment of differentiated homework, assessment of warning learning, and achievement of sharing. After three years of continuous improvements since COVID-19, this online platform has been successfully applied to students and teachers at our university and other pilot universities. A comparison of student teaching data, questionnaire responses and teacher interviews from the Computer Composition Principles course illustrated the sustainability as well as the effectiveness of the method.

Early Fever Is Associated With Clinical Outcomes in Patients With Coronavirus Disease.

Fever is one of the typical symptoms of coronavirus disease (COVID-19). We aimed to investigate the association between early fever (EF) and clinical outcomes in COVID-19 patients. A total of 1,014 COVID-19 patients at the Leishenshan Hospital were enrolled and classified into the EF and non-EF groups based on whether they had fever within 5 days of symptom onset. Risk factors for clinical outcomes in patients with different levels of disease severity were analyzed using multivariable analyses. Time from symptom onset to symptom alleviation, CT image improvement, and discharge were longer for patients with moderate and severe disease in the EF group than in the non-EF group. Multivariable analysis showed that sex, EF, eosinophil number, C-reactive protein, and IL-6 levels were positively correlated with the time from symptom onset to hospital discharge in moderate cases. The EF patients showed no significant differences in the development of acute respiratory distress syndrome, compared with the non-EF patients. The Kaplan-Meier curve showed no obvious differences in survival between the EF and non-EF patients. However, EF patients with increased temperature showed markedly lower survival than the non-EF patients with increased temperature. EF had no significant impact on the survival of critically ill patients, while an increase in temperature was identified as an independent risk factor. EF appears to be a predictor of longer recovery time in moderate/severe COVID-19 infections. However, its value in predicting mortality needs to be considered for critically ill patients with EF showing increasing temperature.

Impact of Public Health Emergency Response to COVID-19 on Management and Outcome for STEMI Patients in Beijing-A Single-Center Historic Control Study.

Coronavirus disease 2019 (COVID-19) pandemic poses great challenge on public health globally. To clarify the impact of COVID-19 pandemic on in-hospital management and outcomes for ST-segment elevation myocardial infarction (STEMI) patients in the nonepicenter. We enrolled consecutive STEMI patients who visited Fuwai Hospital from January to March, 2020 (N = 73) and also established a historical control including all consecutive STEMI patients in the same period of 2019 (N = 95). The primary outcome was defined as a composite endpoint of all-cause death, heart failure, cardiac shock, and cardiac arrest during hospitalization. Emergency response for COVID-19 resulted in a significant 77.6% reduction in the number of primary percutaneous coronary intervention, and a trend toward higher rate of primary composite endpoint (15.1% vs 11.6%, P = 0.51). COVID-19 pandemic results in a significant reduction in emergent reperfusion therapy, and a trend toward higher in-hospital adverse events risk.

Impact of public health emergency response to COVID-19 on management and outcome for NSTEMI patients in Beijing: A single-center historic control.

BACKGROUND: During coronavirus disease 2019 (COVID-19) epidemic, reducing the number of invasive procedure and choosing conservative medication strategy for patients with non-ST-segment elevation myocardial infarction (NSTEMI) is unavoidable. Whether this relatively conservative strategy will impact in-hospital outcome for NSTEMI patients remains unclear. METHODS AND RESULTS: The current study included all consecutive NSTEMI patients who visited the emergency department in Fuwai Hospital from February 1 to March 31, 2020 and all the NSTEMI patients in the same period of 2019 as a historical control. Very-high-risk patients were defined as clinical presentation of heart failure, cardiac shock, cardiac arrest, recurrent chest pain, and life-threatening arrhythmias. The primary outcome was in-hospital major adverse cardiac events (MACE), defined as a composite of all-cause death, recurrent myocardial infarction, or heart failure. A total of 115 NSTEMI patients were enrolled since the outbreak of COVID-19, and a total of 145 patients were included in the control group. There was a tendency toward higher MACE risk in 2020 compared with 2019 (18.3% vs. 11.7%, p = .14). Among very-high-risk patients, early percutaneous coronary intervention (PCI) strategy in 2019 was associated with reduced MACE risk compared with delayed PCI in 2020 (60.6% [20/33] in 2020 vs. 27.9% [12/43] in 2019, p = .01). CONCLUSIONS: COVID-19 pandemic results in a significant reduction in immediate/early PCI and a trend toward higher adverse event rate during hospitalization, particular in very-high-risk patients.

Expert recommendations for diabetes with or without COVID-19 management in communities / 中华内分泌代谢杂志

Since December 2019, the outbreak of coronavirus disease 2019 (COVID-19) has occurred in China. Higher risk of COVID-19 infection and worse prognosis were observed among patients with diabetes. There are rigorous challenges existing in terms of diabetes prevention and glycemic control in primary medical care during period of COVID-19. Here, expert recommendations were developed by Chinese diabetologists, healthcare providers, and public health administrators to improve the ability of primary health facilities and provide standardized basic public health and medical services throughout country. The main contents include basic requirements for management, workflow of health management, referral, treatment, and long-term follow-up.
