Association between the severity of hypothermia and in-hospital mortality in patients with infectious diseases: The J-Point registry.

Aim: Hypothermia is associated with poor prognosis in patients with sepsis. However, no studies have explored the correlation between the severity of hypothermia and prognosis.

Methods: Using data from the Japanese accidental hypothermia network registry (J-Point registry), we examined adult patients aged ≥18 years with infectious diseases whose initial body temperature was ≤35°C from April 1, 2011 to March 31, 2016, in 12 centers.

Clinical relevance of impaired consciousness in accidental hypothermia: a Japanese multicenter retrospective study.

Aim: This study aimed to investigate the association between level of impaired consciousness and severe hypothermia (<28°C) and to evaluate the association between level of impaired consciousness and inhospital mortality among accidental hypothermia patients.

Methods: This was a multicenter retrospective study using the J-Point registry database, which includes data regarding patients whose core body temperature was 35.0°C or less and who were treated as accidental hypothermia in emergency departments between April 1, 2011 and March 31, 2016.

CT-Guided Femoral Approach for Psoas Muscle Abscess Drainage.

Purpose: To evaluate the feasibility and safety of the computed tomography (CT)-guided femoral approach for draining a psoas muscle abscess (PMA).

Materials And Methods: Between January 2014 and November 2018, the CT-guided femoral approach was employed for 9 abscesses in 8 patients who could not tolerate the prone position because of advanced age or other underlying conditions. A 17-gauge blunt metal needle was used to puncture the iliacus muscle below the groin under CT fluoroscopic guidance.

Machine learning-based prediction models for accidental hypothermia patients.

Background: Accidental hypothermia is a critical condition with high risks of fatal arrhythmia, multiple organ failure, and mortality; however, there is no established model to predict the mortality. The present study aimed to develop and validate machine learning-based models for predicting in-hospital mortality using easily available data at hospital admission among the patients with accidental hypothermia.

Method: This study was secondary analysis of multi-center retrospective cohort study (J-point registry) including patients with accidental hypothermia.

Care at critical care medical centers is associated with improved outcomes in patients with accidental hypothermia: a historical cohort study from the J-Point registry.

Aim: The recommendation that patients with accidental hypothermia should be transported to specialized centers that can provide extracorporeal life support has not been validated, and the efficacy remains unclear.

Methods: This was a multicenter retrospective cohort study of patients with a body temperature of ≤35°C presenting at the emergency department of 12 hospitals in Japan between April 2011 and March 2016. We divided the patients into two groups based on the point of care delivery: critical care medical center (CCMC) or non-CCMC.

Osborn Wave Is Related to Ventricular Fibrillation and Tachycardia in Hypothermic Patients.

Background: The Osborn wave (OW) is often observed in hypothermic patients; however, whether OW in hypothermic patients is related to the development of fatal ventricular arrhythmia, including ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT), remains undetermined. This study aimed to estimate the association between OW and the incidence of fatal ventricular arrhythmias.

Methods and results: This retrospective study used the Japanese Accidental Hypothermia Network registry database and included 572 hypothermic patients.

Impact of rewarming rate on the mortality of patients with accidental hypothermia: analysis of data from the J-Point registry.

Background: Accidental hypothermia (AH) is defined as an involuntary decrease in core body temperature to < 35 °C. The management of AH has been progressing over the last few decades, and numerous techniques for rewarming have been validated. However, little is known about the association between rewarming rate (RR) and mortality in patients with AH.

Prognostic ability of the sequential organ failure assessment score in accidental hypothermia: a multi-institutional retrospective cohort study.

Background: Severe accidental hypothermia (AH) is life threatening. Thus, prognostic prediction in AH is essential to rapidly initiate intensive care. Several studies on prognostic factors for AH are known, but none have been established.

Indoor Versus Outdoor Occurrence in Mortality of Accidental Hypothermia in Japan: The J-Point Registry.

The impact of the location where accidental hypothermia (AH) occurs has not been fully investigated thus far. This was a multicenter retrospective study of patients with a body temperature ≤35°C obtained at the emergency department of 12 hospitals in Japan between April 2011 and March 2016. We divided the patients into two groups according to the location where AH occurred (indoor group versus outdoor group).

Correction to: The development and validation of a "5A" severity scale for predicting in-hospital mortality after accidental hypothermia from J-point registry data.

The development and validation of a "5A" severity scale for predicting in-hospital mortality after accidental hypothermia from J-point registry data.

Background: Accidental hypothermia is a serious condition that requires immediate and accurate assessment to determine severity and treatment. Currently, accidental hypothermia is evaluated using the Swiss grading system which uses core body temperature and clinical findings; however, research has shown that core body temperature is not associated with in-hospital mortality in urban settings. Therefore, we developed and validated a severity scale for predicting in-hospital mortality among urban Japanese patients with accidental hypothermia.

Prognostic factors for patients with accidental hypothermia: A multi-institutional retrospective cohort study.

Introduction: In cases of severe accidental hypothermia (AH) in urban areas, the prognostic factors are unknown. We identified factors associated with in-hospital mortality in patients with moderate-to-severe AH in urban areas of Japan.

Method: The J-Point registry database is a multi-institutional retrospective cohort study for AH in 12 Japanese emergency departments.

Characteristics and outcomes of accidental hypothermia in Japan: the J-Point registry.

Background: Accidental hypothermia (AH) has higher incidence and mortality in geriatric populations. Japan has a rapidly ageing population, and little is known about the epidemiology of hypothermia in this country.

Methods: We created an AH registry based on retrospective review of patients visiting the ED of 12 institutions with temperature ≤35°C between April 2011 and March 2016.

The relationship between cerebral regional oxygen saturation during extracorporeal cardiopulmonary resuscitation and the neurological outcome in a retrospective analysis of 16 cases.

Background: In recent years, the measurement of cerebral regional oxygen saturation (rSO) during resuscitation has attracted attention. The objective of this study was to clarify the relationship between the serial changes in the cerebral rSO values during extracorporeal cardiopulmonary resuscitation (ECPR) and the neurological outcome.

Methods: We measured the serial changes in the cerebral rSO values of patients with out-of-hospital cardiac arrest before and after ECPR in Osaka National Hospital.

Pre-hospital portable monitoring of cerebral regional oxygen saturation (rSO2) in seven patients with out-of-hospital cardiac arrest.

Background: In recent years, measurement of cerebral regional oxygen saturation (rSO2) has attracted attention during resuscitation. However, serial changes of cerebral rSO2 in pre-hospital settings are unclear. The objective of this study was to clarify serial changes in cerebral rSO2 of patients with out-of-hospital cardiac arrest (OHCA) in the pre-hospital setting.

Temporal intrailiac balloon occlusion for the treatment of intractable pelvic fracture hemorrhage.

Case: A 48-year-old schizophrenic man sustained multiple injuries following a fall. Unstable pelvic fractures were diagnosed in the emergency department. The patient's hemodynamic status was stabilized following bilateral internal iliac artery embolization using a gelatin sponge.

Negative pressure wound therapy-assisted dermatotraction for the closure of large open wounds in a patient with non-clostridial gas gangrene.

Case: A 53-year-old woman developed septic shock associated with non-clostridial gas gangrene. She presented to the emergency department with two large open wounds on both thighs and in her sacral region. Non-enhanced computed tomography showed air density in contact with the right iliopsoas, which extended to the posterior compartment of the thigh.
