Family factors associated with handwashing behavior among children aged 3 to 12 years in Beijing

Objective To understand the proper handwashing behavior of preschool children and primary school students in Beijing and to analyze associated family factors to provide reference for further health intervention related to handwashing. Methods From November to December 2020 parents of 36 kindergartens and 18 primary schools in 9 districts of Beijing were investigated online by using a self-designed questionnaire with questionnaire star software. The contents of the survey included the basic situation of children and their families parents' correct knowledge of the prevention of novel coronavirus pneumonia their perception of the epidemic risk the provision of handwashing guidance for children and children's handwashing behavior. Results The proportion of proper handwashing of preschool children was 70.2% which was higher than that of primary school students 61.9% χ2 = 57.63 P<0.01. The proportion of parents of preschool children who correctly knew handwashing related knowledge 36.2% 33.4% had low perception of epidemic risk 28.9% 25.4% and provided handwashing guidance 99.1% 97.9% was higher than that of parents of primary school students and the differences were statistically significant χ2 = 6.72 22.84 18.68 P<0.05. But the proportion of parents of preschool children who had high self-efficacy 75.7% 78.2% was lower compared to parents of primary school students χ2 = 6.43 P = 0.04. Multivariate regression results showed that whether preschool children or primary school students urban areas and parents had high self-efficacy low risk perception and provided hand washing guidance for children children were more likely to wash their hands correctly. For preschool children non-only children were 0.79 95%CI= 0.69-0.92 times more likely to wash their hands correctly than only children. For primary school students girls were 1.21 95%CI = 1.06-1.39 times more likely to wash their hands correctly than boys and parents who know knowledge correctly were 1.20 95%CI = 1.04-1.40 times more likely to know it incorrectly P<0.05. Conclusion Proper hand washing behavior of preschool children is higher than that of primary school students. Parental awareness of COVID-19 epidemic handwashing behavior self-efficacy and guidance behavior have effects on the development of children's health behavior. Measures should be taken to enhance parents' awareness of infectious diseases and their ability and self-efficacy of guiding children in disease prevention. © 2022 The authors.

Increasing teleconsultation utilisation for pre-operative anaesthesia evaluation in the COVID-19 pandemic era: a qualityimprovement project

The COVID-19 pandemic has accelerated the growth of telemedicine. Advantages include patient convenience, reduced waiting time, minimising hospital commute and the risk of virus transmission and healthcare cost-savings [1]. Compared with other specialties, anaesthesiology is less engaged with telemedicine- based clinical work and challenges in implementation exist [2]. To align with the Ministry of Health, Singapore COVID-19-safe management measures, pre-anaesthetic assessment via video consultation (VC) workflow was implemented in Sengkang General Hospital, Singapore, in December 2020;however, the referral rate amongst our surgical colleagues remained low. Therefore the aim was to increase the number of VCs by 50% within 12 months (from June 2021) and evaluate patients' experiences. Methods Eligibility criteria included low-risk surgeries (duration < 4 h) with minimal expected blood loss, patients aged 21-65 years, ASA status 1 or 2, body mass index < 35 and the patient's ability to use the Zoom video-conferencing application. Post-consultation, patients were invited to complete an electronic patient satisfaction survey. The main reasons for the low VC referral rate were identified based on ground engagement and feedback. Two plan-do-study-act (PDSA) cycles were conducted to address these issues. PDSA cycle 1 (June 2021): to increase awareness amongst surgeons, surgical champions were engaged to promote VC within their departments;however, the VC referral rate remained low. Therefore, a second PDSA cycle was undertaken. PDSA cycle 2 (October 2021): to increase patient and staff awareness by placing posters publicising VC and enlisting the help of Patient Service Associates (PSAs) to screen for patient eligibility. This led to a significant increase in VC referrals. The current workflow will be evaluated for sustainability. Results Pre-intervention, the average number of monthly VCs was 3, and remained unchanged during PDSA cycle 1. This was increased to 14 during PDSA cycle 2. Discussion VC referrals have increased after the modified workflow, achieving high patient satisfaction and no surgical cancellations. Future work includes developing an automated VC workflow for low-risk surgeries. (Figure Presented).

Brewing, Analysis and Evaluation of Traditional Chinese Rice Wine: An At-Home Interdisciplinary Practical Project during COVID-19 Pandemic Lockdown

Under the threat of the COVID-19 pandemic, an interdisciplinary project about the brewing and analysis of traditional Chinese rice wine was performed at home by junior students of the chemistry major at Huanggang Normal University under the remote guidance of teachers during the spring lockdown semester of 2020. Students were exposed to the concepts of yeast metabolism, analytical testing, and sensory evaluation in terms of real project study and completed a series of hands-on activities at home using readily available materials, utensils, and self-made devices. In the spring semester of 2021, experiments were conducted in the general lab with other students in the same program to compare the results of the two groups of students. The results were that the "home" results were credible, the students were trained not only in laboratory skills but also in analytical and communication skills, and, significantly, the majority of students enjoyed the content and activities. This paper illustrates an effective experimental design procedure that can be conducted at home or in the laboratory in response to uncertain changes, such as a pandemic lockdown.

Dynamic characteristics and transmission mechanism of China's natural gas security situation

Building the index system of China's natural gas security and measuring the index have important meanings for on-line monitoring of natural gas safety, vigilance against potential risks of natural gas and guarantee of energy security. This paper innovatively applies the DMA-TVP-FAVAR model to build China's natural gas security comprehensive index (NGSI) from a dynamic perspective and systematically reviews its dynamic characteristics and transmission mechanism combined with the EEMD method and BP structure breaks test. The main conclusions are as follows: Since 2001, NGSI has shown a wavelike decrease. Specifically, short-term unbalanced factors mainly cause short-term fluctuation of NGSI, the effects of significant events are the main driving force for medium-term fluctuation of NGSI, and natural gas supply and demand fundamentals are the long-term inherent trend of NGSI. Besides, different monetary policy tools have different efficiency on NGSI, and price-based monetary policy instruments are more effective than quantitative monetary policy instruments. © 2022, Editorial Board of Journal of Systems Engineering Society of China.

Platform Incorporating Patient Navigation, Preparative Guidelines, and Hospital at Home May Improve COVID-19 Outcomes for Patients with Myeloid Malignancies

Background: Patients (pts) with malignancies are at increased risk of morbidity and mortality from COVID-19. Among these pts, some of the higher case fatality ratios (CFR) reported are among pts with myeloid malignancies, ranging from 37 to 50% (Mehta V, Cancer Discov 2020;Ferrara F, Leukemia 2020). Levine Cancer Institute (LCI) has a robust hematologic malignancy and cellular therapy program that serves many pts with myeloid malignancies, seeing nearly 100 new diagnoses of acute myeloid leukemia per year. A strategy to mitigate risks associated with COVID-19 was established at LCI in partnership with Atrium Health's (AH) Hospital at Home (HAH). HAH was a system wide platform using telemedicine and home health services to assess and monitor COVID-19 + pts at high risk of complications. To augment HAH for our medically complex cancer pts, a virtual health navigation process involving expertise from across LCI, including a specialized nurse navigation team, was developed to rapidly identify LCI pts + for SARS-CoV-2, monitor them under physician supervision, and escalate care as needed with AH HAH. Along with the navigation platform, data-driven guidelines for detecting, monitoring, and managing LCI pts + for SARS-CoV-2 were swiftly employed across the extensive LCI network. Herein we report on the outcomes for LCI pts with myeloid malignancies + for SARS-CoV-2 and outline the employed risk mitigation strategies and their potential impact on these outcomes. Methods: An automated daily list of LCI pts + for SARS-CoV-2 was provided by AH Information Services. Each pt's chart was reviewed by a nurse navigator for hematologic or oncologic diagnosis, outpatient or inpatient status, and COVID-19 symptoms. Pts without a cancer diagnosis were not assigned a navigator. If hospitalized, a pt was not assigned a navigator;following discharge, if enrolled in HAH, a navigator was assigned. In collaboration with HAH, an algorithm for directing care was utilized (Figure 1). A diagnosis-specific navigator contacted and screened the pt with an assessment tool, which scored pts for surveillance and treatment needs (Table 1). Documentation was forwarded to the primary hematologist/oncologist. Comprehensive guidelines for testing, scheduling, management of + pts, research, and process changes were created, disseminated, and actively updated through LCI's EAPathways. For outcome analysis for pts with myeloid malignancies, pt vital status was updated through data cutoff (7/3/21). Results: From inception on 3/20/20 to 12/2/20, 974 LCI patients were identified as SARS-CoV-2 + and reviewed for nurse navigation. Of the 974 pts, including pts with benign and malignant diagnoses, 488 were navigated. Among all SARS-CoV-2 + LCI pts, 145 (15%) had a hematologic malignancy, including 37 (4%) pts with myeloid malignancies. Characteristics are shown in Table 2. Of the 37 pts, 18 (49%) were navigated. 70% with myeloid malignancies were on active treatment at the time of + test. Nearly 50% of those on active treatment were navigated. 46% were hospitalized with COVID-19, with this being the main reason for no assigned navigator. 24% of hospitalized pts were eventually assigned a navigator. Only 3 pts had undergone allogeneic stem cell transplantation (allo-SCT) with a median time from transplant to detection of SARS-CoV-2 of 9 months (range, 7-23). 2 out of 3 cases post allo-SCT were asymptomatic. No pt died from COVID-19 following allo-SCT. Among the navigated pts with myeloid malignancies, there was no death related to COVID-19. 4 pts, all of whom were hospitalized, died from COVID-19 (N=2, myelodysplastic syndrome with 1 on azacitidine;N=2, myeloproliferative neoplasm, both on hydrea). A CFR of 11% was demonstrated for LCI pts with myeloid malignancies. Conclusions: A multidisciplinary response strategy liaising between AH HAH and LCI followed, assessed, and assisted cancer pts + for SARS-CoV-2. With our embedded nurse navigation team's specialized attention along with enhanced physician oversight and close collaboration with AH HAH, opportunities f r care escalation or adjustments in cancer-focused care were promptly identified. In this setting, among the high-risk population of pts with myeloid malignancies, a lower CFR than has been reported was observed. A virtual navigation platform with HAH capabilities is a feasible, safe, and effective way to monitor and care for this high-risk population.

Gamified mobile health interventions for mental well-being of older adults

Population ageing has raised major concerns about the prevalence of age-related mental health deterioration which is further intensified amid the COVID-19 pandemic. Mobile health (mHealth) interventions bear promising impacts on alleviating the mental health burden of this vulnerable group. However, mHealth solutions often report a high drop-out rate suggesting a lack of motivation and engagement among users. Also, the limited number of clinically validated mHealth applications indicates an urgent demand for empirical evidence on the subject. This paper proposes a design framework for gamified mHealth activities to enhance mental and cognitive well-being of the elderly. Further, the paper outlines a research protocol to investigate the impacts of the framework on a cohort of 250 older adults in a developing country under a single-subject experimental design. Our social experiment may reveal valuable insights into the potential of mHealth solutions and gamification in this domain. © Springer Nature Switzerland AG 2021.

Z-uncertain probabilistic linguistic variables and its application in emergency decision making for treatment of COVID-19 patients

Probabilistic linguistic term sets (PLTSs) have many applications in the field of group decision making (GDM) because it includes both linguistic evaluation and probabilistic distribution when expressing preference information. However, the difference of information credibility in PLTSs is ignored, resulting in an inaccurate representation of decision information and unreasonable probability calculation. In this paper, we first consider the credibility of the information and propose the concept of Z-uncertain probabilistic linguistic variables (Z-UPLVs). Subsequently, the operational rules, normalization, distance and similarity measures, and comparison method of Z-UPLVs are introduced. Then, a probability calculation method based on credibility, an extended TOPSIS method, and some operators are proposed, which can be applied to emergency decision making in the Z-uncertain probabilistic linguistic (Z-UPL) environment. Finally, an emergency decision-making case of COVID-19 patients and comparative analysis illustrate the necessity and effectiveness of this method. © 2020 Wiley Periodicals LLC
