Abstract Background The prevalence of extracorporeal cardiopulmonary resuscitation (ECPR) in patients with out-of-hospital cardiac arrest (OHCA) has been increasing rapidly worldwide. However, guidelines or clinical studies do not provide sufficient data on ECPR practice. aim this study was to real-world for OHCA, including details complications. Methods We did a retrospective database analysis observational multicenter cohort Japan. Adult OHCA presumed etiology who received between 2013 and...

IMPORTANCENeurologically intact survival after out-of-hospital cardiac arrest (OHCA) has been increasing in Japan.However, associations between increased prehospital care, including bystander interventions and increases survival, have not well estimated.OBJECTIVE To estimate the changes neurologically among patients with OHCA Japan.DESIGN, SETTING, AND PARTICIPANTS Retrospective descriptive study using data from Japan's nationwide registry, which started January 2005.The registry includes...

Growth hormone has been shown to contribute seawater adaptation of salmonid fishes. The growth influence is mediated largely by hepatic production insulin-like factor I (IGF-I). To study the hormone-IGF-I axis in osmoregulation, we measured IGF-I mRNA liver, gill, and body kidney from rainbow trout Northern analysis. levels all tissues increased significantly after injection hormone. Transfer fresh water 80% evoked an increase plasma 1 day. was not altered but it gill 8 days, respectively....

Abstract: Brain levels of NADH and NAD + were measured in three models cerebral ischemia to determine whether degradation the pyridine nucleotides is enhanced that generate high concentrations lactic acid. Complete (decapitation), which lactate increased 14 mmol/kg, caused a gradual decrease pool 50% control by 2 h. During focal (occlusion middle artery), was less pronounced (82% at h) despite accentuated accumulation 33 mmol/ kg. In third model (unilateral hypoxia‐ischemia), pretreatment...

We investigated whether patients with out-of-hospital cardiac arrest (OHCA) and sustained ventricular fibrillation/pulseless tachycardia (VF/pVT) or conversion to pulseless electrical activity/asystole (PEA/asystole) benefit more from extracorporeal cardiopulmonary resuscitation (ECPR).

Age is an important factor influencing outcome after severe traumatic brain injury (TBI). In general, the older victim, higher probability of a poor outcome. To investigate mechanism underlying link between age and outcome, data for 797 patients enrolled in Japan Neurotrauma Data Bank (JNTDB), aged 6 years or older, with Glasgow Coma Scale (GCS) scores 8 less on admission deterioration to that level within 48 h impact were analyzed. Thirty-eight percent ages 40 69 years, 24% than years....

<i>Background and Purpose:</i> Stroke risk factors differ depending on the subtype of stroke; moreover, distribution risks is different among countries races. <i>Methods:</i> Mass health screening data were collected from Akita Prefectural Federation Agricultural Cooperative for Health Welfare 1991 to 1998. Cerebrovascular events determined stroke registry 2001. Then, clinical stroke, such as hypertension, hyperlipidemia diabetes mellitus, assessed in subtypes stroke....

This study aimed to investigate whether early epinephrine administration in out-of-hospital cardiopulmonary arrest (OHCA) patients was associated with improved outcomes and address the selection bias inherent observational studies (more severe cases are more likely receive epinephrine).This a retrospective analysis of prospectively collected population-based data adult bystander-witnessed OHCA from nationwide Japanese registry between January 2007 December 2008. To bias, those who attained...

Abstract Objectives It is unclear how much the length of a cardiopulmonary resuscitation ( CPR ) training program can be reduced without ruining its effectiveness. The authors aimed to compare skills 6 months and 1 year after between shortened chest compression–only conventional training. Methods Participants were randomly assigned either compression‐only group, which underwent 45‐minute consisting compressions automated external defibrillator AED use with personal manikins, or 180‐minute...

Background: Selecting an appropriate cannula size is crucial for achieving adequate extracorporeal membrane oxygenation (ECMO) flow rate. However, the association between ECMO and prognosis of patients with out-of-hospital cardiac arrest (OHCA) has not been fully elucidated. We examined associations neurological outcomes survival at discharge in OHCA who received ECMO.

•Hypofibrinogenemia frequently occurs in extracorporeal cardiopulmonary resuscitation (ECPR) and may heighten bleeding risk. This subanalysis of a multicenter observational study (SAVE-J II) included 2,100 adult patients receiving ECPR after out-of-hospital cardiac arrest at 36 facilities Japan.•Overall, 7.5% experienced non-cannulation hemorrhagic complications, those with fibrinogen levels below 140 mg/dL initiation faced significantly higher These findings underscore the importance...
