Background: When a sudden outbreak of an infectious disease occurs, emergency medical services (EMS) response could be negatively affected. The poor prognosis of acute stroke may be largely attributed to delays in treatment. This study aimed to identify the impact of the sudden outbreak of coronavirus disease 2019 (COVID-19) on EMS response for patients with acute stroke. Methods: This comparative cross-sectional study was conducted in 25 safety centers in Seoul, Korea. We enrolled patients with acute stroke who were transferred to the emergency department by EMS. The study period was from February–April 2020 and the same period in 2019. Patients were divided into two groups, pre-COVID-19 period and early-COVID-19 period, and previously collected patient data were analyzed. We performed comparative analyses of EMS response and clinical outcomes between the groups. Results: Of 465 patients, 231 (49.7%) had an acute stroke during the study period. There was no significant difference between clinical characteristics of patients with acute stroke before and after the COVID-19 outbreak. EMS response times increased significantly during the early COVID-19 outbreak. The intensive care unit admission rate and mortality rate increased during the early COVID-19 outbreak. Conclusion: In the initial phase after the sudden COVID-19 outbreak, EMS response times for acute stroke were delayed and the clinical outcomes of patients with acute stroke deteriorated.

These compounds include [Fe(Xqpa)(CN)3][Mn(5-Ysalen)]·<I>p</I>MeOH·<I>q</I>H2O [qpaH2 = <I>N</I>-(quinolin-8-yl)picolinamide; salen = <I>N</I>,<I>N</I>′-ethylenebis(salicylideneiminato) dianion; X = Cl, Y = H (3); X = Cl, Y = Br (4); X = Br, Y = H (5); X = Br, Y = F (6); X = Br, Y = Cl (7); X = Br, Y = Br (8)]. When precursor 1 was used, compounds 3 and 4 were isolated to give a dinuclear entity and a linear chain structure, respectively. The reaction of precursor 2 with the Schiff bases afforded four linear Fe(iii)–Mn(iii) chain complexes. Chain chirality with <I>P</I>- and <I>M</I>-helicity emerges in 4, 7, and 8, while 5 exhibits chain helicity opposite to the previous chain complexes and 6 presents no chain helicity. Such a structural feature is heavily dependent on the interchain π–π contacts and the Fe precursor bridging unit. Chiral induction from a local ethylenediamine link of Y-salen is propagated over the chain <I>via</I> noncovalent π–π interactions. All the bimetallic compounds show antiferromagnetic interactions transmitted by the cyanide linkage. A field-induced metamagnetic transition is involved in 4, 7, and 8, while a field-induced two-step transition is evident in 6. From a magnetostructural viewpoint, the coupling constant is primarily governed by the Mn–Nax–Cax angle (ax = axial) in the bimetallic chain complexes composed of <I>mer</I>-Fe(iii) tricyanides, although the torsion angle plays a role.</P></▼2>

Objective: The purpose of this study was to compare the satisfaction of the Domestic and Imported power wheelchair. Background: Power wheelchair can have a positive impact on user to carry out important activities and to participate in social life. It is growing imported. But, the satisfaction of wheelchair users was not investigated between domestic and imported power wheelchair for usability. Method: 25 domestic power wheelchair and 25 imported power wheelchairs users completed the QUEST2.0 and satisfaction survey for the power wheelchair related usability. Results: The average score of device area of QUEST 2.0 showed more high satisfaction in imported power wheelchair than domestic power wheelchair. The satisfaction survey showed that domestic power wheelchair users were satisfied with physical suitability and efficiency compared to the imported power wheelchair users. Conclusion: we need to develop the power wheelchair with durability and fitness for promoting the satisfaction of users. Application: The results will be reflected in the development of domestic power wheelchair.
