Descriptive analysis of the incidence rate of postacute COVID-19 syndrome in the Republic of Korea Army.

Background: This study aimed to identify the incidence rate of post-coronavirus disease-2019 (COVID-19) conditions in the Republic of Korea (ROK) Army and to investigate the trend of the incidence rate according to changes in dominant variants. Method(s): We used the results of a 19-item, self-completed survey of those who had recovered from COVID-19 in the ROK Army between March 24, 2020, and April 30, 2022. We used both descriptive and multiple logistic regression analyses to identify factors associated with the incidence rate of post-COVID-19 conditions. Result(s): Among the total of 48,623 COVID-19 episodes in the ROK Army, the overall incidence rate of post-COVID-19 conditions was 32.9%. Based on the survey, the incidence of cough was the highest at 15.4%, followed by fatigue (15.1%) and sputum (13.8%). The delta variant had the highest incidence rate of post-COVID-19 conditions at 50.7%, whereas the omicron variant had the lowest at 19.7%. Concerning the type of post-COVID-19 condition, the neuropsychiatric symptoms had the highest incidence at 27.4% when the delta variant was dominant, and the respiratory symptoms were highest at 37.3% when the omicron variant was dominant. In the case of smell and taste symptoms, the incidence rate was high at 21.1% only when the delta variant was predominant. Conclusion(s): The overall incidence rate of post-COVID-19 conditions in the ROK Army was 32.9%. When the delta variant was dominant, the overall incidence as well as the proportion of neuropsychiatric symptoms were high. However, as the omicron variant became dominant, the overall incidence decreased, but the proportion of respiratory symptoms increased.Copyright © Korean Medical Association.

FINE-GRAINED PARALLELISM FOR POST-PANDEMIC CITIES: 12 DESIGN STRATEGIES FOR RESILIENT URBAN PLANNING

The COVID-19 pandemic has changed the way we live in the city. Social distancing will remain as a provisional code of conduct for unforeseeable outbreaks of pandemic diseases in the future. Social distancing is predicated upon reduced density of people in any given space and time. Since urban sprawl has been proved to be unsustainable, spreading out the urban density to suburbs cannot be the right direction to achieve this. Fine-grained parallelism is proposed as a single theoretical framework for an alternative post-pandemic urbanism. It is a way of maintaining simultaneous movement and co-presence, two essential properties of urban living, without the risk of crowding, by reconceptualising the existing spatial setting in a finer resolution. Existing urban spaces that have been underused, ill-used or unused can be reconfigured to achieve fine-grained urbanism for the resilient post-pandemic city. © 2022 Malaysian Institute Of Planners.

Undiagnosed Obstructive Sleep Apnea and Acute COVID-19 Infection-A Case Series

A recently published study on coronavirus disease 2019 (COVID-19) and obstructive sleep apnea (OSA) suggested that there might be an association between certain risk factors and comorbidities associated with OSA, which are also associated with poor COVID-19 outcomes. However, it is unclear whether undiagnosed OSA correlates with COVID-19 severity in a South Korean population. We identified 7 patients who presented with nocturnal hypoxemia during hospitalization due to COVID-19. All patients underwent polysomnography 5-9 weeks after the infection. We retrospectively collected the patients' baseline characteristics, hospital admission data, and polysomnography findings. Of the 7 patients, all were diagnosed with OSA after COVID-19 infection. Their mean (±SD) age was 45.4±16.3 years, 57.1% were men, and their mean (±SD) body mass index was 33.4±6.0 kg/m2. Six patients presented with COVID-19-related pneumonia on chest X-rays, 3 of whom were admitted to the intensive care unit during the acute phase. The overnight polysomnography showed a mean AHI of 59.0±38.5/h and an oxygen desaturation index of 57.6±39.7/h. Undiagnosed OSA is a prevalent condition associated with moderate to severe COVID-19 infection. The study patients with sleep apnea and COVID-19 had obesity and severe oxygen desaturation but did not complain of daytime sleepiness. © This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (https://creativecommons.org/licenses/bync/4.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.

The effectiveness of the combined use of remdesivir and regdanvimab (CT-P59) in patients with severe COVID-19: A single center retrospective study

Background: Although the use of remdesivir and systemic corticosteroids have reduced deaths from COVID-19, COVID-19 still has a high mortality rate. Aims: To know the effectiveness of the combined use of remdesivir and regdanvimab (CT-P59) in patients with severe COVID-19. Methods: From March to early May 2021, 124 severe COVID-19 patients were admitted to Ulsan University Hospital (Ulsan, Korea), and received oxygen therapy and remdesivir. Among them, 25 were administered regdanvimab before oxygen/remdesivir. We retrospectively compared the outcomes of the two groups: remdesivir alone group (n = 99 [79.8%]) vs. regdanvimab/remdesivir group (n = 25 [20.2%]). Results: The oxygen-free days at day 28 (primary outcome), defined as the number of days a patient was alive and oxygen-free for 28 days from oxygen/remdesivir start, were significantly higher in regdanvimab/remdesivir group (mean ± SD [standard deviation]: 19.36 ± 7.87 vs. 22.72 ± 3.66, P = 0.003). The association between the regdanvimab/ remdesivir group and the oxygen-free days was also significant in multivariate analysis (logistic regression), where the initial SpO2/FiO2 ratio (severity index) was adjusted. Further, in the regdanvimab/remdesivir group, the lowest SpO2/FiO2 ratio during treatment was significantly higher (mean ± SD: 237.05 ± 89.68 vs. 295.63 ± 72.74, P = 0.003), and the Kaplan-Meier Estimate of oxygen supplement days in surviving patients (at day 28) were significantly shorter (mean ± SD: 8.24 ± 7.43 vs. 5.28 ± 3.66, P (log-rank test) = 0.024). Conclusions: In severe COVID-19 patients, clinical outcomes could be improved by using regdanvimab in addition to remdesivir.

Propositions for a Resilient, Post-COVID-19 Future for the AEC Industry

The coronavirus outbreak has challenged and continues to challenge every aspect of the supply chain within the AEC industry, forcing stakeholders to cope with increasing uncertainties and continuous change. The notion of resilience is especially salient now. While the need for the AEC industry to focus on resilience has been highlighted in recent articles, there is a need for a comprehensive discussion on what resilience means for the AEC industry and how companies can create built-in resilience. This paper takes the form of a high-level overview of where the industry is headed and aims to establish eleven propositions for a resilient, post-COVID-19 future, for practitioners working in the design and construction industry. Moreover, this paper proposes a 'decentralization of workforce and integration of data' model in which the established propositions are manifested to support a resilient AEC industry.

Effects of the non-face-to-face learning on health-related physical fitness and balance in adolescents according to covid-19

PURPOSE: This study aimed to examine the effects of non-face-to-face learning on health-related physical fitness and balance in adolescents according to the coronavirus disease 2019 (COVID-19). METHODS: Twenty-nine middle-school students (14 girls and 15 boys) were enrolled. We measured the students’ health-related physical fitness (body composition, muscle strength, muscle endurance, flexibility, and cardiac endurance) and balance (static and dynamic) before and after 12 weeks of non-face-to-face learning without any exercise intervention. Cardiac endurance was measured using the Harvard step test. RESULTS: Body fat, muscle strength (hip flexion, hip extension, knee flexion, knee extension), and Y-balance test exhibited significant differences before and after non-face-to-face learning (p<.05). Body fat, muscle strength (hip flexion, hip extension), and Y-Balance test exhibited significant differences in the female group (p<.05). Hip extension muscle strength exhibited a significant difference in the male group (p<.05). Analysis of covariance showed that muscle strength (hip extension and knee extension) and Harvard step of the female group were significantly decreased compared to the male group (p<.05). CONCLUSIONS: Non-face-to-face classes according to COVID-19 had a negative effect on health-related physical fitness and balance in adolescents. Particularly, the muscle strength and cardiac endurance of female adolescents were lower than those of male adoles-cents. © 2021 Korean Society of Exercise Physiology.
