Challenges hindering emergency physicians; involvement in multicenter collaborative studies in Japan: A nationwide survey analysis.

Aim: Multicenter collaborative research accelerates patient recruitment and strengthens evidence. Nevertheless, the factors influencing emergency and critical care physicians' involvement in such research in Japan remain unclear.

Methods: A nationwide web-based survey conducted in early 2023 targeted emergency physicians working a minimum of 3 days per week in Japan.

Japanese rapid/living recommendations on drug management for COVID-19: updated guidelines (July 2022).

Background: Coronavirus disease (COVID-19), an infectious disease caused by the novel coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has spread worldwide since early 2020, and there are still no signs of resolution. The Japanese Clinical Practice Guidelines for the Management of Sepsis and Septic Shock (J-SSCG) 2020 Special Committee created the Japanese Rapid/Living recommendations on drug management for COVID-19 using the experience of creating the J-SSCG.

Methods: The Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) approach was used to determine the certainty of the evidence and strength of recommendations.

Phenytoin versus other antiepileptic drugs as treatments for status epilepticus in adults: a systematic review and meta-analysis.

Aim: Status epilepticus (SE) is a life-threatening neurological emergency. There is insufficient evidence regarding which antiepileptic therapy is most effective in patients with benzodiazepine-refractory convulsive SE. Therefore, this study aimed to evaluate intravenous phenytoin (PHT) and other intravenous antiepileptic medications for SE.

Accidental hypothermia: characteristics, outcomes, and prognostic factors-A nationwide observational study in Japan (Hypothermia study 2018 and 2019).

Aim: This study describes the clinical characteristics and outcomes as well as the prognostic factors of patients with accidental hypothermia (AH) using Japan's nationwide registry data.

Methods: The Hypothermia study 2018 and 2019, which included patients aged 18 years or older with a body temperature of 35°C or less, was a multicenter registry conducted at 87 and 89 institutions throughout Japan, with data collected from December 2018 to February 2019 and December 2019 to February 2020, respectively.

Results: In total, 1363 patients were enrolled in the registry, of which 1194 were analyzed in this study.

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2020 (J-SSCG 2020).

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2020 (J-SSCG 2020), a Japanese-specific set of clinical practice guidelines for sepsis and septic shock created as revised from J-SSCG 2016 jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in September 2020 and published in February 2021. An English-language version of these guidelines was created based on the contents of the original Japanese-language version. The purpose of this guideline is to assist medical staff in making appropriate decisions to improve the prognosis of patients undergoing treatment for sepsis and septic shock.

Head positioning in suspected patients with acute stroke from prehospital to emergency department settings: a systematic review and meta-analysis.

Aim: This study aimed to clarify whether the lying-flat position from prehospital to emergency department settings more effectively improves neurological outcomes of patients suspected with acute stroke over the sitting-up position.

Methods: We searched PubMed, the Cochrane Central Register of Controlled Trials, and Igaku Chuo Zasshi for published randomized controlled trials until September 2019. The study population included patients suspected with acute stroke from prehospital to emergency department settings.

Late i.v. steroid treatment for severe COVID-19-induced acute respiratory distress syndrome: a case report.

Background: The efficacy of steroid treatment for coronavirus disease (COVID-19) is unknown.

Case Presentation: A 67-year-old man was transported to our hospital due to impaired consciousness and respiratory failure. After admission, tracheal aspirate of the patient was harvested, and it tested positive for severe acute respiratory syndrome coronavirus 2 nucleic acid.

Clinical characteristics, prognostic factors, and outcomes of heat-related illness (Heatstroke Study 2017-2018).

Aim: Heat-related illness is common, but its epidemiology and pathological mechanism remain unclear. The aim of this study was to report current clinical characteristics, prognostic factors, and outcomes of heat-related illness in Japan.

Methods: We undertook a prospective multicenter observational study in Japan.

Clinical characteristics of stonefish "Oni-daruma-okoze" envenomation in Japan.

Aim: Stonefish, known in Japan as "Oni-daruma-okoze" ( Block et Schneider), inhabit the waters surrounding the Okinawa/Amami districts. By far, habubites have been limited to these areas mainly due to climatic conditions. Due to changes promoted by global warming and increasing tourism, concerns regarding the potential for stonefish envenomation as well as jellyfish stings on the main island of Japan are increasing.

Clinical characteristics of jellyfish stings in Japan.

Aim: Jellyfish known as "habu-kurage" () inhabit the waters surrounding Okinawa and Amami, Japan, and jellyfish stings are limited to areas outside the Japanese main island. However, the shifts promoted by global warming and increasingly intensive interactions with people have led to concerns regarding the possibility of increased jellyfish stings on the main island of Japan. Similar concerns are being raised all over the world.
