Background: To investigate the value of automatic positioning technology in improving the protection of radiographers in the relocatable CT room of a Fang Cang hospital during the outbreak of coronavirus disease 2019 (COVID-19).Methods: The National Emergency Medical Team of our hospital assumed command of Wuchang Fang Cang Hospital and treated confirmed COVID-19 patients with mild symptoms. Relocatable CT was used to examine patients in this hospital. Automatic positioning technology was applied to avoid close contact between medical staff and patients and to protect medical staff more effectively.Results: Seven hundred lung CT scans acquired from 269 patients were completed from February 17 to 26, 2020 with automatic positioning technology for relocatable CT in a Fang Cang hospital. All scans were conducted successfully using automatic positioning technology. All patients entered the scanning room from a separate door. All the position lines were accurate, and all images met the requirement for diagnosis of COVID-19, with satisfied quality. None of our medical staff had any close contact with patients.Conclusion: Automatic positioning technology applied to relocatable CT can minimize the close contact between technologists and patients and effectively improve the protection of medical staff without sacrificing image quality.

AbstractA novel motion correction algorithm for X-ray lung CT imaging has been developed recently. It was designed to perform for routine chest or thorax CT scans without gating, namely axial or helical scans with pitch around 1.0. The algorithm makes use of two conjugate partial angle reconstruction images for motion estimation via non-rigid registration which is followed by a motion compensated reconstruction. Differently from other conventional approaches, no segmentation is adopted in motion estimation. This makes motion estimation of various fine lung structures possible. The aim of this study is to explore the performance of the proposed method in correcting the lung motion artifacts which arise even under routine CT scans with breath-hold. The artifacts are known to mimic various lung diseases, so it is of great interest to address the problem. For that purpose, a moving phantom experiment and clinical study (seven cases) were conducted. We selected the entropy and positivity as figure of merits to compare the reconstructed images before and after the motion correction. Results of both phantom and clinical studies showed a statistically significant improvement by the proposed method, namely up to 53.6% (p < 0.05) and up to 35.5% (p < 0.05) improvement by means of the positivity measure, respectively. Images of the proposed method show significantly reduced motion artifacts of various lung structures such as lung parenchyma, pulmonary vessels, and airways which are prominent in FBP images. Results of two exemplary cases also showed great potential of the proposed method in correcting motion artifacts of the aorta which is known to mimic aortic dissection. Compared to other approaches, the proposed method provides an excellent performance and a fully automatic workflow. In addition, it has a great potential to handle motions in wide range of organs such as lung structures and the aorta. We expect that this would pave a way toward innovations in chest and thorax CT imaging.

AbstractObjectiveThis study aims at establishing the self-leadership development model (SLM) of China Emergency Medical Team (CEMT) members as a supplement to current selection standards of CEMT members.MethodsRaw dataset was obtained through two ways: in-depth interviews and documentary materials (memoirs and articles). The in-depth interviews were conducted with a purposive sample of 12 CEMT members, all of whom have participated in multiple disaster relief activities and have been CEMT members for more than two years. This paper followed a grounded theory methodology dealing with all data.ResultsBased on tasks, the SLM-CEMT consists of three basic parts: (1) making plans; (2) action; and (3) outcomes. Different parts involve various self-leadership strategies, of which five are the original dimensions of previous research (goal-setting, visualizing successful performance, self-talk, self-reward, and self-correcting feedback) and three are new dimensions (role clarity, self-initiative, and self-vigilance).Conclusions:The SLM-CEMT, with the three new parts, provides a new look at screening CEMT members as well as pondering on future research. Based on the SLM-CEMT, administrators could screen more qualified CEMT members. For the limitations, future work will be on the generalization and confirmation of this model.HaoX,LiX,ZhengJ.Screening China Emergency Medical Team (CEMT) members: a self-leadership perspective.Prehosp Disaster Med.2018;33(6):596–601.

Abstract Background COVID-19 has been giving the devastating impact on the current medical care system. There are quite many guidelines on COVID-19, but only a few on the management of hepatocellular carcinoma (HCC) during COVID-19 pandemic. Aims We develop these recommendations to preserve adequate clinical practice for the management of HCC. Methods Experts of HCC in the Asia–Pacific region exchanged opinions via webinar, and these recommendations were formed. Results Close contact should be minimized to reduce possible exposure of both medical staff and patients to the novel coronavirus. To prevent transmission of the virus, meticulous hygiene measures are important. With the decrease in regular medical service, the medical staff may be mobilized to provide COVID-19-related patient care. However, diagnosis and treatment of HCC should not be delayed because of COVID-19 pandemic. The management of HCC should be the same as in non-pandemic circumstances. HCC is highly malignant, thus it is recommended not to delay curative treatment such as surgery and ablation. However, a kind of triage is necessary even among patients with HCC when resources are insufficient for all to be treated. Curative treatments should be periodized and cytoreductive or non-curative treatment such as vascular interventions and systemic therapy may be postponed until it can be performed safely with sufficient resources. For patients with confirmed or suspected to be infected with the novel coronavirus, diagnosis and treatment should be postponed until the virus is eliminated or they are confirmed as not being infected with it. Conclusions These are collection of measures implemented by front-line medical professionals. We would evolve these recommendations over time as more real-world data becomes available.

ABSTRACT Objectives: After the Nepal earthquake in 2015, for the first time, the Emergency Medical Team Coordination Cell (EMTCC) was activated. This study aims to evaluate the emergency medical team (EMT) coordination in the aftermath of the Nepal earthquake in 2015. Methods: This is a retrospective study that (a) describes the coordination process in Nepal, and (b) reviews and analyzes the EMT database in Nepal to classify the EMTs based on the World Health Organization (WHO) EMT classification, an online survey for EMT coordination, and the Geographic Information System-analyzed EMT distribution. Results: We recorded 150 EMTs, which included 29 Type 1-Mobile, 71 Type 1-Fixed, 22 Type 2, 1 Type 3, and 27 specialist cell recorded EMTs including the military team. The EMTs were allocated based on the number of casualties in that area. The Type 1 EMTs were deployed around Type 2 EMTs. Conclusions: The EMT Classification is useful for the effective posting of EMTs. However, the method of onsite multi registration has room for improvement. The WHO should provide an opportunity for EMTCC training for better coordination of disasters.
