New Normal Remote Communication for Collaboration

Remote communication is not new for the architecture, engineering and construction (AEC) industry and academia. Organisations started using what was common, called "conference rooms” with sophisticated technological equipment prepared for "conference calls” when face-to-face meetings were not possible, and the industries culture and work practices were rooted in face-to-face meetings. This was current practice until the beginning of 2020, with the emergence of the global COVID-19 pandemic. The pandemic forced people to have safe distances between them, to be isolated for long periods of time, and several restrictions to travel not being possible to meet face-to-face. This situation rapidly created a new need to find ways to communicate as alternatives to traditional face-to-face meetings, for "conference call rooms” anywhere and accessible at any time by everyone. The extended duration of the pandemic made organisations adapt to that new normal and remarkable new opportunities arose in a new way. This article explores recent situations in academia and industry that can highlight potential guidance towards the new normal in remote communication for learning–teaching and the AEC industry sectors. In conclusion, appropriate use of these electronic processes provides opportunities to significantly improve remote communication in future. It is expected that the number of opportunities to develop international relationships and partnerships can be boosted to another level of accessibility. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Challenges in Transport Logistics for Modular Construction: A Case Study

Construction logistics is one of the essential functions in the modular construction industry due to the high demand for on-time delivery of components. For modular component suppliers, there is minimal flexibility in delivery times as generally, the installation times of modular components are critical to the contractor’s construction programme. There are several studies conducted in recent years that articulate novel methodologies in construction logistics scheduling;however, the industry still faces challenges in streamlining the whole supply chain to better cater to potential uncertainties that impact construction logistics. This paper looks at a case study on a modular component supplier in Melbourne, with regarding to the challenges faced and how they have effectively overcome these challenges and provides a framework to mitigate construction logistics related discrepancies in the supply chain. The resilience of these methods in facing unforeseen events such as COVID-19 will also be discussed. The overarching objectives of this paper are to include: (1) bibliographic mapping of related publications;(2) identification of current methods, problems and technologies used in modular construction logistics;and (3) propose best practice guidelines that can be implemented to effectively cater to such uncertainties in construction logistics to minimise the impact on the supply chain. Further, incorporating lean principles for planning construction logistics and transport for the modular construction industry is also in discussion. Finally, the potential future research directions are highlighted to guide the researchers to pursue areas of much importance. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

A CASE SERIES OF ACUTE SYMPTOMATIC HYPONATREMIA DUE TO SIADH: AN UNUSUAL PRESENTATION OF COVID-19 INFECTION

Introduction The Syndrome of Inappropriate ADH Secretion (SIADH) is one of the most common causes of hyponatremia among medical inpatients. The evolution of SARS-CoV-2 infection over recent years has led to atypical presentations, one being in the form of acute symptomatic hyponatremia secondary to isolated SIADH not associated with pneumonia. CASES We report a series of three unusual cases of Category 2 COVID-19 infection presenting with acute symptomatic hyponatremia secondary to SIADH. All three patients presented with symptoms of acute severe hyponatremia and coincidentally tested positive for SARSCoV- 2 virus without respiratory tract symptoms and normal chest imaging. All patients were fully vaccinated and boosted at least 3 months before the presentation. Clinical and biochemical workup confirmed SIADH in all three patients. They were treated with hypertonic saline in the initial phase, followed by fluid restriction as per recommendations. It was postulated that the inappropriate ADH secretion was mediated by increased inflammatory cytokines, especially interleukin 6 may be a direct effect of the SARS-CoV-2 infection itself. Conclusion In the context of the ongoing COVID-19 pandemic, acute symptomatic hyponatremia without an obvious cause could be an atypical, isolated manifestation of SARS-CoV-2 infection. Awareness of these uncommon presentations is important so that specific treatment protocols or recommendations can be created and instituted to address this likely reversible but potentially fatal presentation of COVID-19.

Analysis of false negative results in throat swab nucleic acid test of severe acute resporatory syndrome coronavirus 2

Objective To investigate the false negative rate of throat swab nucleic acid test of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and to analyze the causes, so as to provide references for the prevention and control of coronavirus disease 2019 (COVID-19) in China. Methods A retrospective analysis was conducted on the throat swab nucleic acid test results of 1 452 COVID-19 patients admitted to Guanggu Branch of Maternity and Child Healthcare Hospital of Hubei Province from Feb. 19 to Mar. 20, 2020. The negative results before positive results at discharge were judged as false negative results, and the false negative rate was calculated. The discharged patients were followed up to screen for the patients who were positive for nucleic acid test again, and the relationship between the times of consecutive negative nucleic acid tests before discharge and the positive again results was analyzed. Results Among the 1 452 COVID-19 patients, 592 (40.77%) were males and 860 (59.23%) were females. A total of 212 cases (14.60%) had false negative results. Twenty-eight cases (1.93%) were discovered nucleic acid positive again after discharge. Among the 918 patients whose nucleic acid tests were negative for two consecutive times, 24 (2.61%) were positive again, which was significantly higher than that of the patients whose nucleic acid tests were negative for three consecutive times (0.75%, 4/534;χ2=6.21, P=0.012 7). Conclusion The throat swab nucleic acid test of SARS-CoV-2 has a certain proportion of false negative results, which is one of the reasons for COVID-19 patients are found nucleic acid positive again after discharge. Multiple and continuous tests by different testers are recommended before discharge, and negative nucleic acid test for three or more consecutive times can reduce the incidence of nucleic acid positive results again after discharge.
