Kawano, Takahisa; Nishiyama, Kei; Morita, Hiroshi; Yamamura, Osamu; Hiraide, Atsuchi; Hasegawa, Kohei (BMJ Publishing Group, 2016)Objectives: We determined whether crowding at emergency shelters is associated with a higher incidence of sleep disturbance among disaster evacuees and identified the minimum required personal space at shelters. Design: ... -
A comparison of emergency airway management between neuromuscular blockades alone and rapid sequence intubation: an analysis of multicenter prospective study
Sato, Nobuhiro; Hagiwara, Yusuke; Watase, Hiroko; Hasegawa, Kohei (BioMed Central, 2017)Background: Although airway management with neuromuscular blockade (NMB) alone is discouraged in the emergency department (ED), our previous study demonstrated that many patients were intubated using NMBs alone without ... -
A comparison of the force applied on oral structures during intubation attempts between the Pentax-AWS airwayscope and the Macintosh laryngoscope: a high-fidelity simulator-based study
Goto, Tadahiro; Koyama, Yasuaki; Kondo, Takashiro; Tsugawa, Yusuke; Hasegawa, Kohei (BMJ Publishing Group, 2014)Objective: We sought to determine whether the use of Pentax-AWS Airwayscope (AWS) applied less force on oral structures during intubation attempts than a conventional direct laryngoscope (DL). Design: Prospective cross-over ... -
Detection of respiratory syncytial virus and rhinovirus in healthy infants
Hasegawa, Kohei; Linnemann, Rachel W.; Avadhanula, Vasanthi; Mansbach, Jonathan M.; Piedra, Pedro A.; Gern, James E.; Camargo, Carlos A. (BioMed Central, 2015)Background: Despite the research importance of rhinovirus detection in asymptomatic healthy infants, the literature remains sparse. Objective: To investigate the prevalence of respiratory syncytial virus (RSV) and rhinovirus ... -
Differential Time Trends of Outcomes and Costs of Care for Acute Myocardial Infarction Hospitalizations by ST Elevation and Type of Intervention in the United States, 2001–2011
Sugiyama, Takehiro; Hasegawa, Kohei; Kobayashi, Yasuki; Takahashi, Osamu; Fukui, Tsuguya; Tsugawa, Yusuke (Blackwell Publishing Ltd, 2015)Background: Little is known whether time trends of in‐hospital mortality and costs of care for acute myocardial infarction (AMI) differ by type of AMI (ST‐elevation myocardial infarction [STEMI] vs. non‐ST‐elevation [NSTEMI]) ... -
Emergency department visits for acute asthma by adults who ran out of their inhaled medications
Hasegawa, Kohei; Brenner, Barry E.; Clark, Sunday; Camargo, Carlos A. (OceanSide Publications, Inc., 2014)This study was designed to determine the percentage of asthma-related emergency department (ED) visits made by patients who recently ran out of their inhaled short-acting beta-agonists or inhaled corticosteroids and to ... -
Fractional exhaled nitric oxide levels in asthma–COPD overlap syndrome: analysis of the National Health and Nutrition Examination Survey, 2007–2012
Goto, Tadahiro; Camargo, Carlos A; Hasegawa, Kohei (Dove Medical Press, 2016)Purpose Recent studies propose TH2-mediated inflammation in patients with asthma–chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS). However, little is known about whether fractional exhaled nitric oxide ... -
Frequent utilization of the emergency department for acute exacerbation of chronic obstructive pulmonary disease
Hasegawa, Kohei; Tsugawa, Yusuke; Tsai, Chu-Lin; Brown, David FM; Camargo, Carlos A (BioMed Central, 2014)Background: Little is known about patients who frequently visit the emergency department (ED) for acute exacerbation of chronic obstructive pulmonary disease (AECOPD). We aimed to quantify the proportion and characteristics ... -
Mortality trends in U.S. adults with septic shock, 2005-2011: a serial cross-sectional analysis of nationally-representative data
Goto, Tadahiro; Yoshida, Kazuki; Tsugawa, Yusuke; Filbin, Michael R.; Camargo, Carlos A.; Hasegawa, Kohei (BioMed Central, 2016)Background: We aimed to investigate mortality trends in hospitalized patients with septic shock in the US. To achieve this objective, we tested hypothesis that mortality decreased in patients identified by the code of ... -
Multicentre observational study of adults with asthma exacerbations: who are the frequent users of the emergency department in Japan?
Watase, Hiroko; Hagiwara, Yusuke; Chiba, Takuyo; Camargo, Carlos A; Hasegawa, Kohei (BMJ Publishing Group, 2015)Objectives: Emergency department (ED) visits for asthma exacerbation reflect a failure of longitudinal asthma management. However, little is known about the characteristics of patients with frequent ED visits (≥2 visits ... -
Multiple failed intubation attempts are associated with decreased success rates on the first rescue intubation in the emergency department: a retrospective analysis of multicentre observational data
Goto, Tadahiro; Gibo, Koichiro; Hagiwara, Yusuke; Morita, Hiroshi; Brown, David FM; Brown, Calvin A; Hasegawa, Kohei (BioMed Central, 2015)Background: Although the international guidelines emphasize early and systematic use of rescue intubation techniques, there is little evidence to support this notion. We aimed to test the hypothesis that preceding multiple ... -
