OBJECTIVE: This research investigated treatment patterns for out-of-hospital cardiac arrest patients with Do Not Attempt Resuscitation orders in Japanese emergency departments and the associated clinician stress. METHODS: A cross-sectional survey was conducted at 9 hospitals in Okayama, Japan, targeting emergency department nurses and physicians. The questionnaire inquired about the last treated out-of-hospital cardiac arrest patient with a Do Not Attempt Resuscitation. We assessed emotional stress on a 0-10 scale and moral distress on a 1-5 scale among clinicians. RESULTS: Of 208 participants, 107 (51%) had treated an out-of-hospital cardiac arrest patient with a Do Not Attempt Resuscitation order in the past 6 months. Of these, 65 (61%) clinicians used a "slow code" due to perceived futility in resuscitation (42/65 [65%]), unwillingness to terminate resuscitation upon arrival (38/65 [59%]), and absence of family at the time of patient's arrival (35/65 [54%]). Female clinicians had higher emotional stress (5 vs. 3; P = 0.007) and moral distress (3 vs. 2; P = 0.002) than males. Nurses faced more moral distress than physicians (3 vs. 2; P < 0.001). Adjusted logistic regression revealed that having performed a "slow code" (adjusted odds ratio, 5.09 [95% CI, 1.68-17.87]) and having greater ethical concerns about "slow code" (adjusted odds ratio, 0.35 [95% CI, 0.19-0.58]) were associated with high stress levels. CONCLUSIONS: The prevalent use of "slow code" for out-of-hospital cardiac arrest patients with Do Not Attempt Resuscitation orders underscores the challenges in managing these patients in clinical practice.

OBJECTIVES: To determine optional therapeutic strategies by comparing monotherapies and combination therapies to reduce RBC transfusion requirement for patients in the ICU. DATA SOURCES: MEDLINE, CENTRAL, and Embase were searched for studies published from database inception until July 2023. DATA EXTRACTION: We included randomized controlled trials comparing erythropoiesis-stimulating agents (Epo), iron, combination therapy with iron and Epo, hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI), vitamin D3 (VD3), and placebo/no treatment. A frequentist network meta-analysis (NMA) was performed using a random effects model, and the confidence in NMA was rated. DATA SYNTHESIS: Of 117 eligible studies, 75 studies (15,091 patients) were included in the quantitative analysis. Compared with placebo/no treatment, the combination therapy reduces the requirement for RBC transfusion (risk ratio [RR]: 0.60; 95% CI, 0.49-0.74; confidence rating: moderate). The Epo or iron monotherapy may reduce the requirement for RBC transfusion (RR: 0.81; 95% CI, 0.63-1.04; confidence rating: low; RR: 0.83; 95% CI, 0.70-0.98; confidence rating: low, respectively). Combination therapy may not increase the prevalence of both venous thromboembolism (VTE) (RR: 0.73; 95% CI, 0.25-2.08; confidence rating: low) and infection. Epo monotherapy may not increase the prevalence of VTE but may increase that of infections (RR: 1.27; 95% CI, 0.94-1.73; confidence rating: low). Iron monotherapy may not increase the prevalence of both VTE and infection. Evidence for VD3 and HIF-PHI remains uncertain. CONCLUSIONS: Combination therapy with iron and Epo likely reduces the requirement for RBC transfusion and may be less harmful than other therapies.

BACKGROUND: Delirium is a common, yet underdiagnosed neuropsychiatric complication of intensive care unit (ICU) admission, associated with significant mortality and morbidity. Delirium can be difficult to diagnose, with gold standard assessments by a trained specialist being impractical and rarely performed. To address this, various tools have been developed, enabling bedside clinicians to assess for delirium efficiently and accurately. However, the performance of these tools varies depending on factors including the assessor's training. To address the shortcomings of current tools, electronic tools have been developed. AIMS AND OBJECTIVES: The aims of this validation study are to assess the feasibility, acceptability, and generalisability of a recently developed and pilot-tested electronic delirium screening tool (eDIS-ICU) and compare diagnostic concordance, sensitivity, and specificity between eDIS-ICU, Confusion Assessment Method for the ICU (CAM-ICU), and the Diagnostic and Statistical Manual of Mental Disorders - 5th edition (DSM-V) gold standard in diverse ICU settings. METHODS: Seven hundred participants will be recruited across five sites in three countries. Participants will complete three assessments (eDIS-ICU, CAM-ICU, and DSM-V) twice within one 24-h period. At each time point, assessments will be completed within one hour. Assessments will be administered by three different people at any given time point, with the assessment order and assessor for eDIS-ICU and CAM-ICU randomly allocated. Assessors will be blinded to previous and concurrent assessment results. RESULTS: The primary outcome is comparing diagnostic sensitivity of eDIS-ICU and CAM-ICU against the DSM-V. RELEVANCE TO CLINICAL PRACTICE: This protocol describes a definitive validation study of an electronic diagnostic tool to assess for delirium in the ICU. Delirium remains a common and difficult challenge in the ICU and is linked with multiple neurocognitive sequelae. Various challenges to routine assessment mean many cases are still unrecognised or misdiagnosed. An improved ability for bedside clinicians to screen for delirium accurately and efficiently will support earlier diagnosis, identification of underlying cause(s) and timely treatments, and ultimately improved patient outcomes. CLINICAL TRIAL REGISTRATION NUMBER: This study was prospectively registered on the Australian New Zealand Clinical Trials Registry (ANZCTR) on 8th February 2022 (ACTRN12622000220763).

BACKGROUND: Gastric inflation caused by excessive ventilation is a common complication of cardiopulmonary resuscitation. Gastric inflation may further compromise ventilation via increases in intrathoracic pressure, leading to decreased venous return and cardiac output, which may impair out-of-hospital cardiac arrest (OHCA) outcomes. The purpose of this study was to measure the gastric volume of OHCA patients using computed tomography (CT) scan images and evaluate the effect of gastric inflation on return of spontaneous circulation (ROSC). METHODS: In this single-center, retrospective, observational study, CT scan was conducted after ROSC or immediately after death. Total gastric volume was measured. Primary outcome was ROSC. Achievement of ROSC was compared in the gastric distention group and the no gastric distention group; gastric distension was defined as total gastric volume in the ≥75th percentile. Additionally, factors associated with gastric distention were examined. RESULTS: A total of 446 cases were enrolled in the study; 120 cases (27%) achieved ROSC. The median gastric volume was 400 ml for all OHCA subjects; 1068 ml in gastric distention group vs. 287 ml in no gastric distention group. There was no difference in ROSC between the groups (27/112 [24.1%] vs. 93/334 [27.8%], p=0.440). Gastric distention did not have a significant impact, even after adjustments (adjusted odds ratio 0.73, 95% confidence interval [0.42 - 1.29]). Increased gastric volume was associated with longer emergency medical service activity time. CONCLUSIONS: We observed a median gastric volume of 400 ml in patients after OHCA resuscitation. In our setting, gastric distention did not prevent ROSC.

BACKGROUND: Each individual's unique health-related beliefs can greatly impact the patient-clinician relationship. When there is a conflict between the patient's preferences and recommended medical care, it can create a serious ethical dilemma, especially in an emergency setting, and dramatically alter this important relationship. CASE PRESENTATION: A 56-year-old man, who remained comatose after out-of-hospital cardiac arrest, was rushed to our hospital. The patient was scheduled for emergency coronary angiography when his adolescent daughter reported that she and her father held sincere beliefs against radiation exposure. We were concerned that she did not fully understand the potential consequences if her father did not receive the recommended treatment. A physician provided her with in depth information regarding the risks and benefits of the treatment. While we did not want to disregard her statement, we opted to save the patient's life due to concerns about the validity of her report. CONCLUSIONS: Variations in beliefs regarding medical care force clinicians to incorporate patient beliefs into medical practice. However, an emergency may require a completely different approach. When faced with a patient in a life-threatening condition and unconscious, we should take action to prioritize saving their life, unless we are highly certain about the validity of their advance directives.

BACKGROUND: Sudden loss of consciousness as a result of cardiac arrest can cause severe traumatic head injury. Collapse-related traumatic intracranial hemorrhage (CRTIH) following out-of-hospital cardiac arrest (OHCA) may be linked to poor neurological outcomes; however, there is a paucity of data on this entity. This study aimed to investigate the frequency, characteristics, and outcomes of CRTIH following OHCA. METHODS: Adult patients treated post-OHCA at 5 intensive care units who had head computed tomography (CT) scans were included in the study. CRTIH following OHCA was defined as a traumatic intracranial injury from collapse due to sudden loss of consciousness associated with OHCA. Patients with and without CRTIH were compared. The primary outcome assessed was the frequency of CRTIH following OHCA. Additionally, the clinical features, management, and consequences of CRTIH were analyzed descriptively. RESULTS: CRTIH following OHCA was observed in 8 of 345 enrolled patients (2.3%). CRTIH was more frequent after collapse outside the home, from a standing position, or due to cardiac arrest with a cardiac etiology. Intracranial hematoma expansion on follow up CT was seen in 2 patients; both received anticoagulant therapy, and one required surgical evacuation. Three patients (37.5%) with CRTIH had favorable neurological outcomes 28 days after collapse. CONCLUSIONS: Despite its rare occurrence, physicians should pay special attention to CRTIH following OHCA during the post-resuscitation care period. Larger prospective studies are warranted to provide a more explicit picture of this clinical condition.

BACKGROUND: Until recently, calls to the emergency medical service (EMS) from landline phones, which display the caller's exact location at the dispatch center, had been common. Since the use of mobile phones has become widespread, many emergency calls are now made from mobile phones. Differences in outcomes of out-of-hospital cardiac arrest (OHCA) patients for whom EMS was called from mobile versus landline phones has not yet been fully elucidated. METHODS: We performed a retrospective, population-based analysis in Kobe, Japan to examine whether EMS calls from mobiles improved the prognosis of OHCA patients over EMS calls placed from landlines. The primary outcome was favorable neurological outcome, defined as Cerebral Performance Category (CPC) scores of 1 or 2 at discharge. Secondary outcomes were survival at one-month, survival at discharge, and time durations between call and EMS activities. RESULTS: Of 4,231 OHCA cases, 2,194 cases (706 landline cases vs. 1,488 mobile cases) were included in this study. The percentages of favorable neurological outcomes were 0.7% (5/706) in the landline group and 3.8% (56/1,488) in the mobile group. Adjusted multivariable logistic regression revealed that favorable neurological outcomes (odds ratio [OR] 3.03, 95% confidence interval [CI] 1.12-8.17, p = 0.03) were better in the mobile group, while one-month survival (OR 1.30, 95% CI 0.80-2.14, p = 0.29) was not significantly different. Bystander CPR was more frequently administered in the mobile group (landlines 61.3% vs. mobiles 68.4%, p < 0.01). Time durations between call to EMS dispatch (184.5 [IQR 157-220 s] vs. 205 [IQR 174-248 s], p < 0.01) and EMS arrival (476.5 [IQR 377-599 s] vs. 491 [IQR 407.5-611.5 s], p < 0.01) were shorter in the landline group. CONCLUSIONS: Although the landline caller location display system seems effective for shorter times between EMS call and EMS arrival, mobile phone use was associated with better neurological outcomes.

STUDY OBJECTIVE: Early deployment of extracorporeal cardiopulmonary resuscitation (ECPR) is critical in treating refractory out-of-hospital cardiac arrest (OHCA) patients who are potential candidates for ECPR. The effect of prehospital advanced life support (ALS), including epinephrine administration or advanced airway, compared with no ALS in this setting remains unclear. This study's objective was to determine the association between any prehospital ALS care and outcomes of patients who received ECPR with emergency medical services-treated OHCA. METHODS: This was a secondary analysis of data from the Study of Advanced Cardiac Life Support for Ventricular Fibrillation with Extracorporeal Circulation in Japan (SAVE-J) II study. Patients were separated into 2 groups-those who received prehospital ALS (ALS group) and those did not receive prehospital ALS (no ALS group). Multiple logistic regression analysis was used to investigate the association between prehospital ALS and favorable neurological outcomes (defined as Cerebral Performance Category scores 1-2) at hospital discharge. RESULTS: A total of 1289 patients were included, with 644 patients in the ALS group and 645 patients in the no ALS group. There were fewer favorable neurological outcomes at hospital discharge in the ALS group compared with the no ALS group (10.4 vs 19.8%, p <0.001). A multiple logistic regression analysis revealed that any prehospital ALS care (adjusted odds ratios 0.47; 95% confidence interval 0.34-0.66; p <0.001) was associated with unfavorable neurological outcomes at hospital discharge. CONCLUSION: Prehospital ALS was associated with worse neurological outcomes at hospital discharge in patients treated with ECPR for OHCA. Further prospective studies are required to determine the clinical implications of these findings.

OBJECTIVES: To examine the association of prehospital physician presence with neurologic outcomes of pediatric patients with out-of-hospital cardiac arrest (OHCA). DESIGN: Retrospective cohort study. SETTING: Data from the Japanese Association for Acute Medicine-OHCA Registry. INTERVENTIONS: None. PATIENTS: Pediatric patients (age 17 yr old or younger) registered in the database between June 2014 and December 2019. MEASUREMENT AND MAIN RESULTS: We used logistic regression models with stabilized inverse probability of treatment weighting (IPTW) to estimate the associated treatment effect of a prehospital physician with 1-month neurologically intact survival. Secondary outcomes included in-hospital return of spontaneous circulation (ROSC) and 1-month survival after OHCA. A total of 1,187 patients (276 in the physician presence group and 911 in the physician absence group) were included (median age 3 yr [interquartile range 0-14 yr]; 723 [61%] male). Comparison of the physician presence group, versus the physician absence, showed 1-month favorable neurologic outcomes of 8.3% (23/276) versus 3.6% (33/911). Physician presence was associated with greater odds of 1-month neurologically intact survival after stabilized IPTW adjustment (adjusted odds ratio [aOR] 1.98, 95% CI 1.08-3.66). We also found an association in the secondary outcome between physician presence, opposed to absence, and in-hospital ROSC (aOR 1.48, 95% CI 1.08-2.04). However, we failed to identify an association with 1-month survival (aOR 1.49, 95% CI 0.97-2.88). CONCLUSIONS: Among pediatric patients with OHCA, prehospital physician presence, compared with absence, was associated almost two-fold greater odds of 1-month favorable neurologic outcomes.

Both coronavirus disease 2019 (COVID-19) and heat stroke have symptoms of fever or hyperthermia and the difficulty in distinguishing them could lead to a strain on emergency medical care. To mitigate the potential confusion that could arise from actions for preventing both COVID-19 spread and heat stroke, particularly in the context of record-breaking summer season temperatures, this work offers new knowledge and evidence that address concerns regarding indoor ventilation and indoor temperatures, mask wearing and heat stroke risk, and the isolation of older adults. Specifically, the current work is the second edition to the previously published guidance for handling heat stroke during the COVID-19 pandemic, prepared by the "Working group on heat stroke medical care during the COVID-19 epidemic," composed of members from four organizations in different medical and related fields. The group was established by the Japanese Association for Acute Medicine Heatstroke and Hypothermia Surveillance Committee. This second edition includes new knowledge, and conventional evidence gleaned from a primary selection of 60 articles from MEDLINE, one article from Cochrane, 13 articles from Ichushi, and a secondary/final selection of 56 articles. This work summarizes the contents that have been clarified in the prevention and treatment of infectious diseases and heat stroke to provide guidance for the prevention, diagnosis, and treatment of heat stroke during the COVID-19 pandemic.

BACKGROUND: Myxedema coma is an extremely rare but fatal endocrine emergency that requires urgent recognition and treatment. We describe a case of severe hypothermia that rapidly deteriorated to cardiac arrest that was attributed to myxedema coma. CASE PRESENTATION: A 52-year-old man without a history of hypothyroidism was transferred to our emergency department due to coma and profound hypothermia. The patient developed cardiac arrest immediately after hospital arrival but return of spontaneous circulation was achieved shortly after resuscitation. The patient was noted to have generalized, nonpitting edema, dry skin, severe respiratory acidosis, hyponatremia, and elevated creatinine kinase, which was indicative of hypothyroidism. Myxedema coma was confirmed by a thyroid profile. The patient was successfully treated with intravenous levothyroxine and glucocorticoid. CONCLUSION: Although myxedema coma is a rare cause of severe hypothermia, emergency physicians should be familiar with its clinical features and management.

A 67-year-old man was admitted to our hospital with a high fever. Laboratory tests revealed leukopenia, thrombocytopenia, liver dysfunction, rhabdomyolysis, and hyperferritinemia. He was diagnosed with severe fever with thrombocytopenia syndrome (SFTS) complicated by hemophagocytic lymphohistiocytosis and treated with steroid therapy, intravenous calcium channel blocker (CCB), and supportive care, without favipiravir. Serum levels of ferritin and soluble interleukin 2 receptor (sIL2R) were markedly elevated on Day 3 after admission and decreased thereafter, while an SFTS viral load of 6.8×104 copies/μL was detected on Day 2, increasing to 2.9×105 copies/μL on Day 6. Serum ferritin and sIL2R levels may be better indicators of mortality than the SFTS viral load, and CCBs may have a therapeutic effect.

BACKGROUND: Identifying dysphagia as a potential complication of sepsis may improve swallowing function and survival while decreasing hospital length of stay. OBJECTIVES: Our goal was to determine the frequency of dysphagia in sepsis survivors on the 7th day after admission, as well as their associated factors and outcomes. METHODS: This single-centre, retrospective, observational study analysed data from sepsis survivors admitted to Okayama Saiseikai General Hospital from 2018 to 2019. Participants with sepsis were assigned to one of two study groups based on the presence or absence of dysphagia using the criterion of Functional Oral Intake Scale score <5 on the 7th day after admission. We used multivariate logistic regression to determine factors independently associated with dysphagia on the 7th day after admission. Multivariate logistic regression was also used to determine associations between groups and outcomes, including dysphagia on hospital discharge, direct discharge home (discharge of patients directly to their home), and total dependency (Barthel Index score ≤20) on hospital discharge. RESULTS: One hundred one patients met the study inclusion criteria, 55 with dysphagia and 46 without dysphagia. Fasting period (adjusted odds ratio [AOR]: 1.31, 95% confidence interval [CI]: 1.07-1.59) and enteral tube feeding (AOR: 8.56, 95% CI: 1.95-37.5) were independently associated with the presence of dysphagia on the 7th day after admission. Dysphagia on the 7th day after admission was associated with dysphagia on hospital discharge (AOR: 46.0, 95%, CI: 7.90-268.3), a lower chance of direct discharge home (AOR: 0.03, 95% CI: 0.01-0.15), and a higher incidence of total dependency (AOR: 9.30, 95% CI: 2.68-32.2). CONCLUSIONS: We found that dysphagia was commonly encountered post sepsis. Fasting period and enteral tube feeding were independently associated with dysphagia on the 7th day after admission. Dysphagia on the 7th day after admission was also associated with dysphagia on hospital discharge, nondirect discharge home, and dependency in activities of daily living at the time of hospital discharge.

BACKGROUND Refeeding syndrome (RFS) is a life-threatening syndrome, which can cause sudden death. RFS has been reported frequently in young patients with anorexia without organic disease; however, there are few reports in elderly patients with organic disease. Herein, we report a case of cardiac arrest after refeeding syndrome associated with hiatal hernia. CASE REPORT We report the case of a 59-year-old woman who had a diagnosis of RFS during treatment for anorexia secondary to hiatal hernia. She was hospitalized with hypothermia, anemia, and hypovolemic shock and treated with electrolytes, hydration, and transfusion at the Emergency Department. Upper gastrointestinal endoscopy revealed hiatal hernia with severe reflux esophagitis. We initiated parenteral nutrition (8.7 kcal/kg/day). However, QTc prolongation caused pulseless ventricular tachycardia. Temporary cardiac pacing was performed to prevent recurrence. Her nutritional status steadily improved, and she was transferred to another hospital without complications. CONCLUSIONS Patients with gastrointestinal comorbidities are more likely to have inadequate food intake and to be undernourished on admission and therefore should be carefully started on nutritional therapy, considering their risk of RFS.

BACKGROUND: Post-extubation dysphagia (PED) is recognized as a common complication in the intensive care unit (ICU). Speech and language therapy (SLT) can potentially help improve PED; however, the impact of the timing of SLT initiation on persistent PED has not been well investigated. This study aimed to examine the timing of SLT initiation and its effect on patient outcomes after extubation in the ICU. METHODS: We conducted this multicenter, retrospective, cohort study, collecting data from eight ICUs in Japan. Patients aged ≥ 20 years with orotracheal intubation and mechanical ventilation for longer than 48 h, and those who received SLT due to PED, defined as patients with modified water swallowing test scores of 3 or lower, were included. The primary outcome was dysphagia at hospital discharge, defined as functional oral intake scale score < 5 or death after extubation. Secondary outcomes included dysphagia or death at the seventh, 14th, or 28th day after extubation, aspiration pneumonia, and in-hospital mortality. Associations between the timing of SLT initiation and outcomes were determined using multivariable logistic regression. RESULTS: A total of 272 patients were included. Of them, 82 (30.1%) patients exhibited dysphagia or death at hospital discharge, and their time spans from extubation to SLT initiation were 1.0 days. The primary outcome revealed that every day of delay in SLT initiation post-extubation was associated with dysphagia or death at hospital discharge (adjusted odds ratio (AOR), 1.09; 95% CI, 1.02-1.18). Similarly, secondary outcomes showed associations between this per day delay in SLT initiation and dysphagia or death at the seventh day (AOR, 1.28; 95% CI, 1.05-1.55), 14th day (AOR, 1.34; 95% CI, 1.13-1.58), or 28th day (AOR, 1.21; 95% CI, 1.07-1.36) after extubation and occurrence of aspiration pneumonia (AOR, 1.09; 95% CI, 1.02-1.17), while per day delay in post-extubation SLT initiation did not affect in-hospital mortality (AOR, 1.04; 95% CI, 0.97-1.12). CONCLUSIONS: Delayed initiation of SLT in PED patients was associated with persistent dysphagia or death. Early initiation of SLT may prevent this complication post-extubation. A randomized controlled study is needed to validate these results.

BACKGROUND: Emergency medical technicians (EMTs) may be subjected to emotional stress during patient treatment/transport. In Japan, dispatched EMTs must attempt resuscitation in all cases of out-of-hospital cardiac arrest (OHCA), including patients with "do not attempt resuscitation" (DNAR) orders and patients whose families do not support resuscitation. We described the characteristics, prevalence, and outcomes of OHCA/DNAR patients, and aimed to identify factors associated with EMT stress when treating them. METHODS: We included OHCA patients transported by EMTs in the city of Okayama from 2015 to 2019. We identified patients with DNAR orders based on emergency medical service (EMS) records, then EMTs completed questionnaires regarding the management of those patients and EMTs' emotions. RESULTS: Among 3079 eligible OHCA patients, 122 patients (4%) had DNAR orders (DNAR group), and 2957 (96%) patients had no DNAR orders (no DNAR group). Based on responses from 243 EMT participants involved in OHCA/DNAR transports, we divided EMTs into high stress (73/243, 30%) and low stress (170/243, 70%) groups. EMTs experienced emotional stress from treating patients with family physician orders to transport (AOR: 4.74, 95% CI: 2.35-9.56) and those for whom prehospital defibrillation was performed (AOR: 20.7, 95% CI: 3.10-137.9). CONCLUSIONS: Approximately 30% of EMTs providing resuscitation to OHCA/DNAR patients experienced high levels of stress. Establishment of a prehospital emergency system incorporating physician medical direction and updated guidelines for treating patients with DNAR orders may reduce the psychosocial stress of EMTs.

INTRODUCTION: Sepsis is not only the leading cause of death in the intensive care unit (ICU) but also a major risk factor for physical and cognitive impairment and mental disorders, known as postintensive care syndrome (PICS), reduced health-related quality of life (HRQoL) and even mental health disorders in patient families (PICS-family; PICS-F). The ABCDEF bundle is strongly recommended to overcome them, while the association between implementing the bundle and the long-term outcomes is also unknown. METHODS AND ANALYSIS: This is a multicentre prospective observational study at 26 ICUs. All consecutive patients between 1 November 2020 and 30 April 2022, who are 18 years old or older and expected to stay in an ICU for more than 48 hours due to sepsis or septic shock, are enrolled. Follow-up to evaluate survival and PICS/ PICS-F will be performed at 3, 6 and 12 months and additionally every 6 months up to 5 years after hospital discharge. Primary outcomes include survival at 12 months, which is the primary outcome, and the incidence of PICS defined as the presence of any physical impairment, cognitive impairment or mental disorders. PICS assessment scores, HRQoL and employment status are evaluated. The association between the implementation rate for the ABCDEF bundle and for each of the individual elements and long-term outcomes will be evaluated. The PICS-F, defined as the presence of mental disorders, and HRQoL of the family is also assessed. Additional analyses with data up to 5 years follow-up are planned.

BACKGROUND: Although optimal prehospital airway management after out-of-hospital cardiac arrest (OHCA) remains undetermined, no studies have compared different advanced airway management (AAM) policies adopted by two hospitals in charge of online medical direction by emergency physicians. We examined the impact of two different AAM policies on OHCA patient survival. METHODS: This observational cohort study included adult OHCA patients treated in Okayama City from 2013 to 2016. Patients were divided into two groups: the O group - those treated on odd days when a hospital with a policy favoring laryngeal tube ventilation (LT) supervised, and the E group - those treated on even days when the other hospital with a policy favoring endotracheal intubation (ETI) supervised. Multiple logistic regression analysis was performed to assess airway device effects. The primary outcome measure was seven-day survival. RESULTS: Of 2,406 eligible patients, 50.1% were in the O group and 49.9% were in the E group. O group patients received less ETI (1.0% vs. 12.0%) and more LT (53.3% vs. 43.0%) compared with E group patients. In univariate analysis, no differences were observed in seven-day survival (9.4% vs 10.1%). Multiple regression analysis revealed neither LT nor ETI had a significant independent effect on seven-day survival, considering bag-valve mask ventilation as a reference (OR, 0.78; 95% CI, 0.54 to 1.13, OR, 0.79; 95% CI, 0.36 to 1.72, respectively). CONCLUSION: Despite different advanced airway medical direction policies in a single city, there were no substantial impact on outcomes for OHCA patients.

PURPOSE: Although the most recent systematic review and meta-analyses on acute respiratory distress syndrome (ARDS) have shown that the use of steroids decreases mortality in adult patients, its benefits and risks may differ depending on the type and dosage of the steroid. Therefore, we conducted a network meta-analysis (NMA) to compare the differences in the efficacy among different doses and types of steroids. METHODS: We searched MEDLINE, CENTRAL, ICHUSHI, ClinicalTrials.gov, and WHO ICTRP databases from the earliest records to March 2021 for randomized control trials, which compared steroids with placebo or conventional therapy for ARDS. Using the random-effects model, we compared various categories of steroids (high-dose methylprednisolone, low-dose methylprednisolone, hydrocortisone, dexamethasone, and no steroid) concerning hospital mortality, incidence of infection, and ventilator-free days (VFD). RESULTS: We analyzed nine studies involving adult patients (n = 1212). Although there were no significant differences between the groups in terms of the mortality and incidence of infection, the number of VFD were greater when using low-dose methylprednisolone than when not using any steroids (Mean difference: 6.06; 95% confidence intervals: [2.5, 10.5]). Moreover, the rank probability showed that low-dose methylprednisolone might be the optimal treatment, whereas using no steroid or high-dose methylprednisolone may be inferior to other treatments in terms of mortality, infection, and VFD. CONCLUSION: This NMA suggested that the effect of steroids on the outcome in patients with ARDS might depend on the type of the steroid drug administered. Moreover, further studies are needed to identify the optimal type and dosage.

Hamman's syndrome is an uncommon clinical entity characterized by an idiopathic spontaneous pneumomediastinum as a result of a sudden increase in intra-alveolar pressure. It can be triggered by repeated vomiting or Kussmaul breathing associated with diabetic ketoacidosis (DKA). Careful attention to this particular condition is needed to avoid under-diagnosis and to provide optimal management. Herein, we report a case of an 18-year-old man complaining of chest discomfort and progressive weight loss, ultimately diagnosed with Hamman's syndrome secondary to DKA. The patient's symptoms disappeared after intravenous fluid and insulin administration, while his pneumomediastinum resolved following conservative treatment. Our report highlights the importance of recognition of the links between pneumomediastinum as a cause of chest pain in patients with DKA.

Oral benzine intake with suicidal tendencies is an uncommon life-threatening respiratory emergency without a treatment regimen.  A 50-year-old man attempted suicide with 100 ml of oral benzine intake and developed severe acute respiratory distress syndrome (ARDS) with hydrocarbon aspiration. He received mechanical ventilation with placement in the prone position and low tidal volume, neuromuscular blocking agents, bronchoalveolar lavage, steroid pulse therapy, antibiotics, and sivelestat sodium hydrate. He was transferred to the psychiatric hospital five days after admission without any adverse events. ARDS associated with oral benzine intake could be treated with general treatments for ARDS.

Spontaneous bladder rupture is an uncommon and life-threatening urological emergency, and early diagnosis is often challenging. Herein, we report a case of intraperitoneal bladder rupture in an 81-year-old male with neurogenic bladder-the case of intraperitoneal bladder rupture required late laparotomy for pelvic abscess following initial conservative treatment. An eighty-one-year-old male presented to our emergency department with deterioration of consciousness, fever, and hematuria. He denied previous trauma history and had been treated for neurogenic bladder. Physical examination revealed signs of tenderness in the abdomen. A diagnosis of bladder rupture was made based on laboratory examination indicating renal failure and radiological imaging showing urinary ascites. Conservative management with a Foley catheter and antibiotics (meropenem administered 1 g/day) was initiated. On day seven after admission, the patient complained of abdominal pain and fever, and a diagnosis of pelvic abscess based on contrast-enhanced computed tomography and septic peritonitis was made. An emergency exploratory laparotomy for peritoneal drainage was performed. The postoperative course was uneventful, and the patient was discharged on day 29 after admission. Urinary bladder rupture should always be considered as a differential diagnosis in patients presenting with free fluid in the abdomen, peritonitis, reduced urine output, and hematuria. Clinicians should be aware that secondary bacterial peritonitis can occur as a major complication of a ruptured urinary bladder.

Recombinant human thrombomodulin (rhTM) is an anti-coagulant used to treat disseminated intravascular coagulation (DIC). The efficacy of rhTM in patients with sepsis-induced DIC has been proved in some clinical trials, but the determining factors are not known. The aim of this study was to identify patients for whom rhTM will be effective and the factors that determine rhTM efficacy in alleviating DIC. A single-center, retrospective, observational study was conducted in patients with sepsis-induced DIC who were treated with rhTM in Okayama Saiseikai General Hospital (Okayama, Japan) between January 2010 and December 2019. Among 67 patients who were treated with rhTM, DIC was resolved in 24 patients. The multivariate logistic regression analysis revealed that age (odds ratio (OR) 1.05; 95% confidence interval (CI) 1.00-1.10; p < 0.05) and acute physiology and chronic health evaluation II scores (OR 0.88; 95% CI 0.78-0.98; p < 0.05) were factors that determined rhTM efficacy in alleviating DIC. Overall, our study provides valuable information on factors that should be considered before rhTM administration to patients with sepsis-induced DIC for a better management of healthcare costs.

A 52-year-old man with consciousness disorder following a 2-day history of general fatigue, diarrhea, vomiting and excessive thirst was admitted to our hospital. Severe hyperglycemia (1,739 mg/dL) with a slightly elevated HbA1c level (6.9%), ketonuria and low C-peptide level (0.07 ng/mL) confirmed the diagnosis of fulminant type 1 diabetes mellitus (FT1DM). Following sudden unexplained cardiogenic shock shortly after the initiation of insulin therapy with no evidence of myocardial ischemia assessed by coronary angiography, the patient was supported with percutaneous venoarterial extracorporeal membrane oxygenation. Electron microscopic analysis of the myocardium revealed massive lipid droplets without the infiltration of inflammatory cells. His left ventricular function began to recover during the following days and returned to a normal level on day 14. Currently, the impact of FT1DM on intramyocardial lipid deposition is poorly understood. However, this case suggests that even short-term exposure to high concentrations of glucose can be responsible for lipotoxicity followed by severe cardiac dysfunction.

AIM: The rapid response system (RRS) is an in-hospital medical safety system. To date, not much is known about patient disposition after RRS activation, especially discharge home. This study aimed to investigate the prevalence, characteristics, and outcomes of patients with adverse events who required RRS activation. METHODS: Retrospective data from the In-Hospital Emergency Registry in Japan collected from April 2016 to November 2020 were eligible for our analysis. We divided patients into Home Discharge, Transfer, and Death groups. The primary outcome was the prevalence of direct discharge home, and independently associated factors were determined using multivariable logistic regression. RESULTS: We enrolled 2,043 patients who met the inclusion criteria. The prevalence of discharge home was 45.7%; 934 patients were included in the Home Discharge group. Age (adjusted odds ratio [AOR] 0.96; 95% confidence interval [CI], 0.95-0.97), malignancy (AOR 0.69; 95% CI, 0.48-0.99), oxygen administration before RRS (AOR 0.49; 95% CI, 0.36-0.66), cerebral performance category score on admission (AOR 0.38; 95% CI, 0.26-0.56), do not attempt resuscitation order before RRS (AOR 0.17; 95% CI, 0.10-0.29), RRS call for respiratory failure (AOR 0.50; 95% CI, 0.34-0.72), RRS call for stroke (AOR 0.12; 95% CI, 0.03-0.37), and intubation (AOR 0.20; 95% CI, 0.12-0.34) were independently negative, and RRS call for anaphylaxis (AOR 15.3; 95% CI, 2.72-86.3) was positively associated with discharge home. CONCLUSION: Less than half of the in-hospital patients under RRS activation could discharge home. Patients' conditions before RRS activation, disorders requiring RRS activation, and intubation were factors that affected direct discharge home.

A 65-year-old Japanese woman developed vesicular eruptions on her right ear due to varicella zoster virus (VZV) reactivation, followed by cranial polyneuritis and meningitis affecting her right cranial nerves V, VII, VIII, IX, and X. After acyclovir administration, her facial paralysis worsened. Intravenous methylprednisolone and vitamin C were administered on Day 4 post-admission. Her symptoms steadily improved, and by Day 45 she had fully recovered. Cranial polyneuritis is a rare complication of VZV reactivation, and there is no established method of treatment. This is the first report of full recovery from cranial polyneuritis using intravenous vitamin C as ancillary treatment.

BACKGROUND: Reye's syndrome (RS) is a rare but severe acute life-threating disease characterized by encephalopathy and fatty liver damage. Reye's syndrome is most common in children and rarely occurs in adults. CASE PRESENTATION: A 56-year-old woman was admitted to the emergency department with disturbance of consciousness and respiratory failure. She had taken ibuprofen for headache. Her Glasgow Coma Scale score was E3V3M5 on admission. The laboratory findings revealed acute liver failure with prothrombin time - international normalized ratio of 3.16, aspartate aminotransferase 12,548 IU/L, alanine aminotransferase 5,725 IU/L, and blood ammonia 102 μg/dL. Head magnetic resonance imaging showed hyperintense signals on diffusion-weighed images of globus pallidus.We diagnosed the patient with RS induced by influenza A and use of ibuprofen. The patient received supportive care in the intensive care unit and her clinical outcome was favorable. CONCLUSION: Ibuprofen might be a risk factor for RS.

AIM: Femoral neck fractures in elderly patients needing oxygen therapy are often encountered in the emergency department. This single-center, retrospective, observational study aimed to examine the frequency, cause, and factors related to hypoxia in elderly patients with femoral neck fractures. METHODS: We analyzed data from 241 patients admitted to Okayama Saiseikai General Hospital (Okayama, Japan) from April 2016 to March 2019. Hypoxia was defined as PaO2 / FiO2 ratio under 300. The independent factors for hypoxia were determined by multiple logistic regression analysis. RESULTS: There were 194 patients who met the study inclusion criteria, 148 in the non-hypoxia group and 46 in the hypoxia group. The hypoxia group included patients with pneumonia (n = 3), chronic obstructive pulmonary disease (n = 2), pulmonary edema (n = 1), and pulmonary embolization (n = 1). The cause of hypoxia was undetermined in 39 cases. However, occult fat embolism syndrome was suspected in 29 of these 39 cases based on Gurd and Wilson criteria after considering clinical examination results. Barthel indexes were significantly lower in the hypoxia group on discharge. Age (adjusted odds ratio [OR] 1.07; 95% confidence interval [CI], 1.00-1.14; P = 0.038), D-dimer (adjusted OR 1.02; 95% CI, 1.00-1.03; P = 0.005), and transtricuspid pressure gradient (adjusted OR 1.03; 95% CI, 1.00-1.07; P = 0.015) were independently associated with the hypoxia. CONCLUSION: We found that hypoxia, including undetermined hypoxia, was commonly encountered in the emergency department. Hypoxia in elderly patients with femoral neck fractures was associated with age, D-dimer, and transtricuspid pressure gradient and needs further investigation.

AIM: To examine the change in vertebral bone mineral density (BMD) using abdominal computed tomography in patients treated for sepsis. METHODS: A single-center, retrospective, observational study was undertaken to evaluate BMD after critical care at Okayama Saiseikai General Hospital (Okayama, Japan) from January 2016 to April 2018. Sepsis was defined as an absolute increase of ≥2 in Sequential Organ Failure Assessment score in the intensive care unit or high care unit. Bone mineral density was evaluated in Hounsfield units (HU) by computed tomography. Patients were divided into groups based on the presence or absence of osteoporosis, which was defined as average vertebral body HU <110. Paired t-tests were used to compare the mean BMD of each vertebra between before and after critical care. We also analyzed accidental bone fracture events after discharge. The survival rate was analyzed as an outcome using the Kaplan-Meier method. RESULTS: Fifty-two of 188 patients met the inclusion criteria. We found significant differences between admission and follow-up vertebral BMD values in the spine at the thoracic 12, lumbar 1-5, and sacrum 1 levels (P < 0.05), especially in the non-osteoporosis groups. No difference in mortality was observed between patients with osteoporosis and those without. Two of 19 patients with osteoporosis developed a bone fracture. CONCLUSION: We found that sepsis was associated with loss in BMD following critical care.

AIM: We aimed to examine the relationship between kidney size and contrast-induced nephropathy (CIN) in patients who underwent contrast-enhanced computed tomography (CT) in the emergency department. METHODS: This single-center retrospective observational study was undertaken to evaluate risk factors for CIN at Okayama Saiseikai General Hospital (Okayama, Japan) from January 2014 through to December 2016. Contrast-induced nephropathy was defined as an absolute increase in serum creatinine level of ≥0.5 mg/dL or ≥25% over the baseline value within 72 h after contrast-enhanced CT. Independent risk factors for CIN were determined by multiple logistic regression analysis. The thickness of the kidney was evaluated as a predictor of CIN using the area under the receiver operating characteristic curve. We also analyzed CIN as an outcome using the Kaplan-Meier method. RESULTS: The incidence of CIN was 26/262 (9.9%). In the multivariate analysis, CIN was associated with renal thickness (odds ratio = 0.65; 95% confidence interval, 0.53-0.81). No patient underwent renal replacement therapy. CONCLUSION: Renal thickness could be used as a reliable, simple, and easily obtainable marker for identifying CIN in patients undergoing contrast-enhanced CT in the emergency department.

Cases: Spontaneous spinal epidural hematoma (SSEH) is an uncommon disease. Most SSEH cases involve back and/or neck pain. We report the cases of two men who experienced SSEH with dysstasia but without back or neck pain. Outcomes: This study presents two cases involving elderly Japanese men who visited an emergency department because of sudden dysstasia without back or neck pain. The results of the neurological examinations revealed ataxic gait. Cervical spinal epidural hematomas were observed by computed tomography and magnetic resonance imaging. One patient underwent hematoma removal and decompression by corpectomy, whereas the other patient received conservative treatment and observation. The patients were discharged without sequelae. Conclusion: Spinal epidural hematomas are difficult to diagnose, and a delayed diagnosis can adversely affect the patient's quality of life. These hematomas should be considered in the differential diagnosis of cerebrovascular diseases.

Case: Contrast medium-induced transient leukopenia is very rare. Here, we report a case of a 73-year-old man diagnosed with contrast media-induced transient leukopenia. The patient underwent abdominal contrast-enhanced computed tomography, where he was given non-ionic iodinated contrast medium i.v. His medical history included an allergic reaction to a different contrast medium. One hour later, the patient was admitted to the emergency department complaining of chest discomfort. He had leukopenia and a fever (temperature of 38.9°C). Complete blood count showed a white blood cell count of 930/μL and an absolute neutrophilic count of 232/μL. Outcome: The patient was given i.v. antibiotics and 5 mg chlorpheniramine maleic acid, 20 mg famotidine, and 125 mg methylprednisolone. The patient's white blood cell count recovered the next day, and he was discharged after 2 days of hospitalization. Conclusion: We diagnosed the patient with contrast media-induced transient leukopenia, which is a rare phenomenon.
