ABSTRACT Purpose: To make a further evaluation of perioperative outcomes between the robot-assisted radical prostatectomy (RARP) and open radical prostatectomy (ORP), we conducted a comparison and trend analysis by using the Nationwide Inpatient Sample (NIS) from 2009 to 2014. Materials and Methods: Adult prostate cancer patients with radical prostatectomy were abstracted from the NIS. RARP and ORP were identified according to the International Classification of Diseases, 9th Revision, Clinical Modification procedure codes. The perioperative outcomes included blood transfusion, intraoperative and postoperative complications, prolonged length of stay (pLOS), and in-hospital mortality. Propensity score matching method and multivariable logistic regression model were performed to adjust for the pre-defined covariates. The annual percent change (APC) was used to detect the change trend of rates for outcomes. Results: A total of 77.054 patients were included in our study. According to the results of propensity score matching analyses, RARP outperformed ORP in blood transfusion (1.96% vs. 9.40%), intraoperative complication (0.73% vs. 1.25%), overall postoperative complications (8.87% vs. 11.97%), and pLOS (13.39% vs. 36.70%). We also found that there was a significant decreasing tendency of incidence in blood transfusion (APC=-9.81), intraoperative complication (APC=-12.84), and miscellaneous surgical complications (APC=-14.09) for the RARP group. The results of multivariable analyses were almost consistent with those of propensity score matching analyses. Conclusions: The RARP approach has lower incidence rates of perioperative complications than the ORP approach, and there is a potential decreasing tendency of complication incidence rates for the RARP.

The recently emerged coronavirus disease (COVID-19), which has been characterised as a pandemic by the World Health Organization (WHO), is impacting all parts of human society including agriculture, manufacturing, and tertiary sectors involving all service provision industries. This paper aims to give an overview of potential host reservoirs that could cause pandemic outbreak caused by zoonotic transmission. Amongst all, continues surveillance in slaughterhouse for possible pathogens transmission is needed to prevent next pandemic outbreak. This paper also summary the potential threats of pandemic to agriculture and aquaculture sector that control almost the total food supply chain and market. The history lesson from the past, emerging and reemerging infectious disease including the Severe Acute Respiratory Syndrome (SARS) in 2002, Influenza A H1N1 (swine flu) in 2009, Middle East Respiratory Syndrome (MERS) in 2012 and the recent COVID-19 should give us some clue to improve especially the governance to be more ready for next coming pandemic. Highlights • Urbanization promotes the occurrence of zoonotic diseases transmission. • The outbreak of COVID19 affected the global food supply chain. • In preparedness to prevent pandemic outbreak, the continues surveillance of food safety is obligated.

The covid-19 emergency presented daunting challenges for all in higher education, in particular teachers and students who were forced to quickly pivot from the familiar setting of the campus to purely online education in a matter of days. Despite the enormity of this challenge the transition was negotiated successfully in terms of online teaching though issues such as social interaction, student isolation and digital divides remained largely unaddressed. In Sweden, the pandemic response has been a wake-up call to address the lack of national coordination of online and blended education as well as the need for more coordinated approaches to professional pedagogical development. This paper outlines the response of several national networks and stakeholder organisations, notably the Network for IT in Higher Education (ITHU), though the forming of a mutual support group on Facebook to coordinating workshops and sharing resources. A survey of ITHU members revealed a number of key focus areas for national coordination as well as the development of a culture of sharing between teaching staff and educational technicians that did not exist before the pandemic.

The COVID-19 pandemic has shone a light on handwashing as an inexpensive, widely applicable response measure. In consequence, most governments have taken action to promote access to water and sanitation services for all. This paper documents an overview of initiatives and interventions that countries have implemented during the first months of the COVID-19 response. Initiatives have been identified across 84 countries worldwide, and categorized into those that aimed at securing water, sanitation, and hygiene (WASH) for all, and those that sought to provide technical and financial support to service providers. The pandemic has not hit countries in the same way. Accordingly, results show disparities in the response between and within regions, with the level of activity found in the countries varying largely in terms of ambition and scope. Hygiene promotion and infection prevention and control (IPC) has been widely adopted – at least one response measure found in 94% of mapped countries -, although not always matched in ambition with the assured availability of soap, water, and handwashing facilities. Support to vulnerable households to promote basic access to WASH services at scale was weak (38% of countries) or implemented locally (25%), and requiring additional focus, particularly in rural areas and small towns. In addition, parallel support needs to be extended to service providers or to households themselves in the form of cash transfers, in order to ensure the financial viability and the continuity of services. All lessons learned distilled from the pandemic should help strengthen the enabling environment for more resilient services in future emergencies. Areas for focus could include developing specific pandemic response strategies and plans; strengthening coordination; and establishing emergency financial support mechanisms for water operators, for example. Overall, findings presented herein contribute to enhance current and future pandemics prevention, mitigation, and recovery. Graphical abstract Unlabelled Image

Safe water and sanitation, which give rise to appropriate hygiene, are fundamental determinants of individual and social health and well-being. Thereby, assessing and widening access to sustainable, durable water and sanitation infrastructure remains a global health issue. Rural areas are already at a disadvantage. Poor access to water, sanitation, and hygiene (WASH) can have a major negative effect on students in rural schools. Thus, the paper aims to assess the current condition and the challenge to access WASH in rural Kazakh schools. The study was conducted in three rural schools in Central Kazakhstan. Data were gathered through a survey among pupils, observations of the WASH infrastructure and maintenance, and a face-to-face interview with school administrators. The mean survey response rate was 65% across schools. Results indicated there was no alternative drinking-water source in schools, and 15% of students said they had access to water only occasionally. Half of the students reported that the water was unsafe to drink because of a poor odor, taste, or color. The toilet in school 3 was locked with a key, and a quarter of the students reported there was no access to a key. Moreover, not having gender-separated toilet facilities was a challenge because of the traditional gender norms. Despite the effective regulations and measures of handwashing taken during COVID-19, 27.7% of the students answered that soap was not offered daily in classrooms. Additionally, warm water was only provided in school 2. About 75% of students did not have access to drying materials continuously. The study shows that having the schools’ infrastructure is not enough when characteristics, such as availability, accessibility, maintenance, operation, quality of services, education, and practices, are ignored. Cooperation between local education authorities, school administration, and parents should be encouraged to the achievement of the sustainable development goals (SDGs) by 2030.

The COVID-19 pandemic has wreaked havoc in every country in the world, with serious health-related, economic, and social consequences. Since its outbreak in March 2020, many researchers from different fields have joined forces to provide a wide range of solutions, and the support for this work from artificial intelligence (AI) and other emerging concepts linked to intelligent data analysis has been decisive. The enormous amount of research and the high number of publications during this period makes it difficult to obtain an overall view of the different applications of AI to the management of COVID-19 and an understanding of how research in this field has been evolving. Therefore, in this paper, we carry out a scientometric analysis of this area supported by text mining, including a review of 18,955 publications related to AI and COVID-19 from the Scopus database from March 2020 to June 2021 inclusive. For this purpose, we used VOSviewer software, which was developed by researchers at Leiden University in the Netherlands. This allowed us to examine the exponential growth in research on this issue and its distribution by country, and to highlight the clear hegemony of the United States (USA) and China in this respect. We used an automatic process to extract topics of research interest and observed that the most important current lines of research focused on patient-based solutions. We also identified the most relevant journals in terms of the COVID-19 pandemic, demonstrated the growing value of open-access publication, and highlighted the most influential authors by means of an analysis of citations and co-citations. This study provides an overview of the current status of research on the application of AI to the pandemic.

AbstractThis article analyses organizational change and new ways of working in one of our most institutionalized and professionalized contexts—the courts. Here, digital technologies and the implementation of digital work practices carry great promise as they enable more accessible and qualitative services to be produced more efficiently and effectively. While prior studies have shown that institutionalized and professionalized actors are reluctant to respond to change, attempts to change work practices through digital technologies remain understudied. In particular, we do not know how COVID-19 has influenced the motivation and implementation of digitalized work. This article draws on a large Swedish administrative court and its attempts to digitalize its work starting in 2018. We find that several barriers first inhibited a successful transformation of work practices. These barriers were connected to the institution of the court and the institutionalized profession of judges, which worked together in preventing organizational change. However, COVID-19 radically accelerated the digital implementation of work practices and gave rise to two separate re-assessment processes. The first established new motivations for digitalized work, and the second allowed for a new perception of value in digital work. These processes effectively broke down perceived barriers and substantially facilitated a more successful digital transformation of working practices.

Simple Summary The COVID-19 pandemic has exerted a substantial impact on small-scale broiler production systems in developing countries and put their supply chains at risk of disruption. Drawing on a survey of 205 small-scale commercial broiler farms (SCBFs) in Egypt, this study identifies the primary pathways through which the pandemic has affected these farms and investigates the determinants of their perception of COVID-19 effects. The empirical results revealed that the pandemic affected SCBFs heterogeneously based on their management and production systems and resource endowment. In particular, individually owned farms and those with membership of poultry producer organizations and larger total asset values perceived significantly fewer effects. In addition, SCBFs operating in both local and provincial markets were less likely to perceive negative effects from the pandemic. Despite that the adoption of strict containment measures was essential for protecting public health, our results indicate that policy responses to COVID-19 must consider the likely effects on small businesses such as SCBFs since disruptions to such socioeconomically important supply chains will intensify human suffering from the pandemic. These findings of our study provide important implications for enhancing the preparedness and resilience of small-scale broiler production systems in developing countries to future pandemics and natural hazards. Abstract As in many other countries, the outbreak of the COVID-19 pandemic, together with subsequent government containment measures, posed significant challenges to small-scale broiler production systems in Egypt. Based on a survey of 205 specialist small-scale commercial broiler farms (SCBFs) consisting of both farm-based and household-based production systems, this study identifies the primary pathways through which COVID-19 has affected SCBFs and investigates the determinants of farm perception of these effects. A polychoric principal component analysis sorted the effects of the pandemic on the SCBFs surveyed into five categories, namely, input availability, production and operational costs, labor and human resources, consumer demand and sales, and farm finances. Next, five ordered logit models were constructed to examine the determinants of the SCBFs’ perception of each category of these effects. Generally, the empirical results revealed that COVID-19 affected SCBFs heterogeneously based on their management and production systems and resource endowment. Female-led and household-based SCBFs perceived significantly greater COVID-19 effects. In contrast, individually owned farms and those with membership of poultry producer organizations and larger total asset values perceived fewer effects. In addition, SCBFs operating in both local and provincial markets were less likely to perceive negative effects from the pandemic on their broiler farming activities. Although the adoption of strict and immediate containment measures was essential for controlling the virus and protecting public health, our results indicate that policy responses to COVID-19 must consider the likely effects on small businesses such as SCBFs since disruptions to such socioeconomically important supply chains will intensify human suffering from the pandemic. Overall, our findings provide important implications for the formulation of effective strategies for mitigating the impact of COVID-19 on small-scale broiler production systems in Egypt and enhancing their preparedness and resilience to future pandemics, natural hazard risks, and market shocks.

4D printing technology, as a new generation of Additive Manufacturing methods, enables printed objects to further change their shapes or other properties upon external stimuli. One main category of 4D printing research is 4D printed thermal Shape Memory Polymer (SMP). Its morphing process has large time delay, is nonlinear time variant, and susceptible to unpredictable disturbances. Reaching an arbitrary position with high precision is an active research question. This paper applies the Reinforcement Learning (RL) method to develop an optimal control method to perform closed loop control of the SMP actuation. Precise and prompt shape morphing is achieved compared with previous control methods using a PI controller. The training efforts of RL are further reduced by simplifying the optimal control policy using the structural property of the prior trained results. Customized protective visors against COVID-19 are fabricated using the proposed control method. © 2021 The Author(s)
