RESUMEN
PURPOSE: To assess the performance of the post-cardiac arrest (CA) prognostication strategy algorithm recommended by the European Resuscitation Council (ERC) and the European Society of Intensive Care Medicine (ESICM) in 2020. METHODS: This was a retrospective analysis of the Korean Hypothermia Network Prospective Registry 1.0. Unconscious patients without confounders at day 4 (72-96 h) after return of spontaneous circulation (ROSC) were included. The association between the prognostic factors included in the prognostication strategy algorithm, except status myoclonus and the neurological outcome, was investigated, and finally, the prognostic performance of the prognostication strategy algorithm was evaluated. Poor outcome was defined as cerebral performance categories 3-5 at 6 months after ROSC. RESULTS: A total of 660 patients were included in the final analysis. Of those, 108 (16.4%) patients had a good neurological outcome at 6 months after CA. The 2020 ERC/ESICM prognostication strategy algorithm identified patients with poor neurological outcome with 60.2% sensitivity (95% CI 55.9-64.4) and 100% specificity (95% CI 93.9-100) among patients who were unconscious or had a GCS_M score ≤ 3 and with 58.2% sensitivity (95% CI 53.9-62.3) and 100% specificity (95% CI 96.6-100) among unconscious patients. When two prognostic factors were combined, any combination of prognostic factors had a false positive rate (FPR) of 0 (95% CI 0-5.6 for combination of no PR/CR and poor CT, 0-30.8 for combination of No SSEP N20 and NSE 60). CONCLUSION: The 2020 ERC/ESICM prognostication strategy algorithm predicted poor outcome without an FPR and with sensitivities of 58.2-60.2%. Any combinations of two predictors recommended by ERC/ESICM showed 0% of FPR.

INTRODUCTION: We investigated the clinical characteristics, outcomes and factors related to the serious adverse events (AEs) of patients visiting the emergency department (ED) with various AEs after ChAdOx1 and mRNA COVID-19 vaccination. METHODS: Patients with AEs who visited the ED between March 2021 and September 2021 were selected from three EDs. The clinical data of these patients were collected by retrospectively reviewing medical records. Serious adverse events (AEs) were defined as any adverse medical events that led to hospital admission. RESULTS: A total of 3572 patients visited the ED with AEs; 69.6% were administered mRNA vaccines, and the median (IQR) age was 48 (31-63) years. Regarding chief complaints, chest pain/discomfort (43.7%) was most common in the mRNA vaccines group, while fever (15.8%) was more commonly presented in the ChAdOx1 group. Most patients (93.9%) were discharged from the ED. In multivariate analysis, age ≥70 years, days from vaccination to ED visit ≥8 days, fever and dyspnea as chief complaints were higher independent risk factors for serious AEs (OR 27.94, OR 2.55, OR 1.95 and OR 2.18: p < 0.001, p < 0.001, p = 0.003 and p = 0.003, respectively). CONCLUSION: Most patients who visited the ED with AEs after vaccination were discharged from the ED regardless of the type of vaccine. Emergency physicians need to differentiate serious AEs and consider factors that may require admission to the ED.

BACKGROUND: Sepsis is a series of organ failures caused by dysregulated responses to infection. Risk factors for sepsis are multiple comorbidities, a poor nutrition status, and limited mobility. The primary purpose of the study was to determine whether ambulation ability with albumin and C-reactive protein are predictive of 28-day mortality of elderly patients with sepsis. METHODS: This was a retrospective observational study using a multicentre-based registry of elderly patients between November 2016 and February 2017. The inclusion criteria were a patient ≥65 years and a diagnosis of sepsis and exclusion criteria were a patient with covariates of ambulation ability such as central nervous system diseases, or malignancy. The area under the receiver operating characteristic curve of prediction models were calculated and compared. The survival rates according to the ambulation ability were estimated and compared by the log-rank test. RESULTS: 2291 patients ≥65 years visited with infectious diseases. 496 subjects with central nervous system diseases, 710 subjects with malignancy and 817 subjects with a Sequential Organ Failure Assessment score ≤ 1 were excluded. Ultimately, 278 subjects were included in the primary analysis. 133 (47.8%) subjects were male and the median age was 78 years. 228 (82%) subjects could ambulate independently before morbidity and 28 (10.1%) subjects expired in 28 days. In the inability to ambulate and C-reactive protein to albumin ratio model, the area under the curve predicting 28-day mortality was 0.761 with no significant difference from the Sequential Organ Failure Assessment score (0.859, p = 0.097) and the estimated survival rate on 28th day according to the ability to ambulate showed a significant difference (hazard ratio = 1.212, p < 0.001). CONCLUSION: The premorbid ambulation ability with albumin and C-reactive protein can be combined to predict 28-day mortality in elderly patients with sepsis.

OBJECTIVES: The aim of this study was to evaluate the prognostic performance of the peak amplitude of P25/30 cortical somatosensory evoked potentials in predicting nonawakening in targeted temperature management-treated cardiac arrest patients. DESIGN: Prospective analysis. SETTING: Four academic tertiary care hospitals. PATIENTS: Eighty-seven cardiac arrest survivors after targeted temperature management. INTERVENTIONS: Analysis of the amplitude of P25/30. MEASUREMENTS AND MAIN RESULTS: In all participants, somatosensory evoked potentials were recorded after rewarming, and bilaterally absent pupillary and corneal reflexes were evaluated at 72 hours after the return of spontaneous circulation. We analyzed the amplitudes of the N20 and P25/30 peaks and the N20-P25/30 complex in cortical somatosensory evoked potentials. Upon hospital discharge, 87 patients were dichotomized into the awakening and nonawakening groups. The lowest amplitudes of N20, P25/30, and N20-P25/30 in the awakening patients were 0.17, 0.45, and 0.73 µV, respectively, and these thresholds showed a sensitivity of 70.5% (95% CI, 54.8-83.2%), 86.4% (95% CI, 72.7-94.8%), and 75.0% (95% CI, 59.7-86.8%), respectively, for nonawakening. The area under the curve of the P25/30 amplitude was significantly higher than that of the N20 amplitude (0.955 [95% CI, 0.912-0.998] vs 0.894 [95% CI, 0.819-0.969]; p = 0.036) and was comparable with that of the N20-P25/30 amplitude (0.931 [95% CI, 0.873-0.989]). Additionally, adding resuscitation variables or an absent brainstem reflex to the P25/30 amplitude showed a trend toward improving prognostic performance compared with the use of other somatosensory evoked potential amplitudes (area under the curve, 0.958; 95% CI, 0.917-0.999 and area under the curve, 0.974; 95% CI, 0.914-0.996, respectively). CONCLUSIONS: Our results provide evidence that the absence of the P25/30 peak and a reduction in the P25/30 amplitude may be considered prognostic indicators in these patients.

BACKGROUND: The effect of renal replacement therapy (RRT) on the outcomes of severe acute kidney injury (AKI) after out-of-hospital cardiac arrest (OHCA) is uncertain. This study aimed to evaluate the association of RRT with 6-month mortality in patients with severe AKI treated with targeted temperature management (TTM) after OHCA. METHODS: This was a retrospective analysis of a prospectively collected multicentre observational cohort study that included adult OHCA patients treated with TTM across 22 hospitals in South Korea between October 2015 and December 2018. AKI was diagnosed using the Kidney Disease: Improving Global Outcomes criteria. The primary outcome was 6-month mortality and the secondary outcome was cerebral performance category (CPC) at 6 months. Multivariate Cox regression analysis was performed to define the role of RRT in stage 3 AKI. RESULTS: Among 10,426 patients with OHCA, 1373 were treated with TTM. After excluding those who died within 48 h of return of spontaneous circulation (ROSC) and those with pre-arrest chronic kidney disease, our study cohort comprised 1063 patients. AKI developed in 590 (55.5%) patients and 223 (21.0%) had stage 3 AKI. Among them, 115 (51.6%) were treated with RRT. The most common treatment modality among RRT patients was continuous renal replacement therapy (111 [96.5%]), followed by intermittent haemodialysis (4 [3.5%]). The distributions of CPC (1-5) at 6 months for the non-RRT vs. the RRT group were 3/108 (2.8%) vs. 12/115 (10.4%) for CPC 1, 0/108 (0.0%) vs. 1/115 (0.9%) for CPC 2, 1/108 (0.9%) vs. 3/115 (2.6%) for CPC 3, 6/108 (5.6%) vs. 6/115 (5.2%) for CPC 4, and 98/108 (90.7%) vs. 93/115 (80.9%) for CPC 5, respectively (P = 0.01). The RRT group had significantly lower 6-month mortality than the non-RRT group (93/115 [81%] vs. 98/108 [91%], P = 0.04). Multivariate Cox regression analyses showed that RRT was independently associated with a lower risk of death in patients with stage 3 AKI (hazard ratio, 0.569 [95% confidence interval, 0.377-0.857, P = 0.01]). CONCLUSION: Dialysis interventions were independently associated with a lower risk of death in patients with stage 3 AKI treated with TTM after OHCA.

BACKGROUND: Community-based active contact and follow-up are known to be effective in reducing the risk of repeat suicide attempts among patients admitted to emergency departments after attempting suicide. However, the characteristics that define successful collaborations between emergency departments and community-based mental healthcare centers in this context are not well known. METHODS: This study investigated patients visiting the emergency department after suicide attempts from May 2017 to April 2019. Patients were classified in either the successful collaboration group or the failed collaboration group depending on whether or not they were linked to a community-based follow-up intervention. Clinical features and socioeconomic status were considered as independent variables. Logistic regression analysis was performed to identify factors influencing the collaboration. RESULTS: Of 674 patients, 153 (22.7%) were managed successfully via the targeted collaboration. Completion of hospital-based psychological counseling (adjusted odds ratio [aOR], 233.55; 95% confidence interval [CI], 14.99-3,637.67), supported out-of-pocket expenses (aOR, 11.17; 95% CI, 3.03-41.03), Korean Triage and Acuity Scale 1-3 (aOR, 4.31; 95% CI, 1.18-15.73), suicide attempt associated with mental disorder (aOR, 0.15; 95% CI, 0.04-0.52), and self-discharge against medical advice (aOR, 0.12; 95% CI, 0.02-0.70) were independent factors influencing the collaboration. CONCLUSION: Completion of hospital-based psychological counseling was the most highly influential factor determining the outcome of the collaboration between the emergency department and community-based mental healthcare center in the management of individuals who had attempted suicide. Completion of hospital-based psychological counseling is expected to help reduce the risk of repeat suicide attempts.

BACKGROUND: We hypothesized that the absence of P25 and the N20-P25 amplitude in somatosensory evoked potentials (SSEPs) have higher sensitivity than the absence of N20 for poor neurological outcomes, and we evaluated the ability of SSEPs to predict long-term outcomes using pattern and amplitude analyses. METHODS: Using prospectively collected therapeutic hypothermia registry data, we evaluated whether cortical SSEPs contained a negative or positive short-latency wave (N20 or P25). The N20-P25 amplitude was defined as the largest difference in amplitude between the N20 and P25 peaks. A good or poor outcome was defined as a Glasgow-Pittsburgh Cerebral Performance Category (CPC) score of 1-2 or 3-5, respectively, 6 months after cardiac arrest. RESULTS: A total of 192 SSEP recordings were included. In all patients with a good outcome (n = 51), both N20 and P25 were present. Compared to the absence of N20, the absence of N20-P25 component improved the sensitivity for predicting a poor outcome from 30.5% (95% confidence interval [CI], 23.0-38.8%) to 71.6% (95% CI, 63.4-78.9%), while maintaining a specificity of 100% (93.0-100.0%). Using an amplitude < 0.64 µV, i.e., the lowest N20-P25 amplitude in the good outcome group, as the threshold, the sensitivity for predicting a poor neurological outcome was 74.5% (95% CI, 66.5-81.4%). Using the highest N20-P25 amplitude in the CPC 4 group (2.31 µV) as the threshold for predicting a good outcome, the sensitivity and specificity were 52.9% (95% CI, 38.5-67.1%) and 96.5% (95% CI, 91.9-98.8%), respectively. The predictive performance of the N20-P25 amplitude was good, with an area under the receiver operating characteristic curve (AUC) of 0.94 (95% CI, 0.90-0.97). The absence of N20 was statistically inferior regarding outcome prediction (p < 0.05), and amplitude analysis yielded significantly higher AUC values than did the pattern analysis (p < 0.05). CONCLUSIONS: The simple pattern analysis of whether the N20-P25 component was present had a sensitivity comparable to that of the N20-P25 amplitude for predicting a poor outcome. Amplitude analysis was also capable of predicting a good outcome.

PURPOSE: The density ratio of gray matter (GM) to white matter (WM) on brain computed tomography (CT) (gray-to-white matter ratio, GWR) helps predict the prognosis of comatose patients after cardiac arrest. However, Hounsfield units (HU) are not an absolute value and can change based on imaging parameters and CT scanners. We compared the density of brain GM and WM and the GWR by using images scanned with different types of CT machines. METHOD: 102 patients with normal readings who were scanned using three types of CT scanners were included in the study. HU were measured at the basal ganglia level by two observers with circular regions of interest. RESULT: The difference in GM was 0.98-10.30 HU and WM was 1.05-7.55 HU. The mean value of measured HU and GWR were different for each CT group. The ANOVA test showed significant difference all variables. The post hoc test for GWR, which was used to compare the differences between each scanner, was statistically significant. Interclass correlation coefficients of measured GM and WM between the two observers were very high (Cronbach's α=0.995 and 0.990, respectively) and GWR was showed good confidence level (0.798). CONCLUSION: In this study, the HU values of GM and WM in the normal adult brain differed up to 23% among scanners. Unfortunately, the GWR may not compensate for the HU difference between GM and WM occurring between scanners. Therefore, rather than applying consistent GWR cut-offs, the protocol or manufacturer differences between imaging scanners should be considered.

PURPOSE: Drowning is one of the major causes of traumatic death. The impact of drowning in the elderly and patients who were not elderly will be different because of physiological differences. We wanted to analyze the clinical differences such as mortality, incidence rate of complications, degree of hypothermia and rate of cardiac arrest between elderly and adult drowning patients. METHODS: This study included drowning patients over 18â¯years old who came to an emergency department (ED) located on a riverside from September 1997 to July 2016. Patients over the age of 65â¯years were classified as elderly, while those under the age of 65â¯years were classified as adults. Demographic data and clinical outcomes were surveyed. RESULTS: A total of 611 patients were included in this study. Sixty-one patients (9.9%) were elderly, and 550 patients (90.1%) were adults. There were 17 elderly patients (15.8%) and 87 adult patients (27.9%) who had cardiac arrest at the time of ED arrival (pâ¯=â¯0.017). The rate of body temperaturesâ¯<â¯34⯰C was higher in elderly patients than that in adult patients (27.9% vs 17.5%, respectively, pâ¯=â¯0.025). The rates of hospitalization in the intensive care unit (ICU) and mortality were higher in elderly group (23% vs. 15.1%, respectively, pâ¯=â¯0.01; 37.7% vs 21.8%, respectively, pâ¯=â¯0.01). There was no significant difference in suicidal intent between the elderly and adult patient groups (82.0% vs 78.9%, respectively, pâ¯=â¯0.421). CONCLUSIONS: Elderly drowning patients accounted for approximately 1/10 of all drowning cases and were more likely to experience a cardiac arrest, hypothermia, mortality, and ICU admission.

OBJECTIVE: Hyperoxia could lead to a worse outcome after cardiac arrest. The aim of this study was to investigate the relationship between the cumulative partial pressure of arterial oxygen (PaO2) and neurological outcomes after cardiac arrest treated with targeted temperature management. DESIGN: Retrospective analysis of a prospective cohort. SETTING: An academic tertiary care hospital. PATIENTS: A total of 187 consecutive patients treated with targeted temperature management after cardiac arrest. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The area under the curve of PaO2 for different cutoff values of hyperoxia (≥ 100, ≥ 150, ≥ 200, ≥ 250, and ≥ 300 mm Hg) with different time intervals (0-24, 0-6, and 6-24 hr after return of spontaneous circulation) was calculated for each patient using the trapezoidal method. The primary outcome was the neurologic outcome, as defined by the cerebral performance category, at 6 months after cardiac arrest. Of 187 subjects, 77 (41%) had a good neurologic outcome at 6 months after cardiac arrest. The median age was 54 (43-69) years, and 128 (68%) were male. The area under the curve of PaO2 with cutoff values of greater than or equal to 200, greater than or equal to 250, and greater than or equal to 300 was higher in the poor outcome group at 0-6 and 0-24 hours. The adjusted odds ratios of area under the curve of PaO2 greater than or equal to 200 mm Hg were 1.659 (95% CI, 1.194-2.305) for 0-24 hours after return of spontaneous circulation and 1.548 (95% CI, 1.086-2.208) for 0-6 hours after return of spontaneous circulation. With a higher cumulative exposure to oxygen tension, we found significant increasing trends in the adjusted odds ratio for poor neurologic outcomes. CONCLUSION: In a new method for PaO2 analysis, cumulative exposure to hyperoxia was associated with neurologic outcomes in a dose-dependent manner. Greater attention to oxygen supply during the first 6 hours appears to be important for outcome after cardiac arrest.

OBJECTIVES: The absence of N20 somatosensory evoked potential after cardiac arrest is related to poor outcome. However, discrimination between the low-amplitude and the absence of N20 is challenging. P25 and P30 are short-latency positive peaks with latencies between 25 and 30 ms following N20 (P25/30). P25/30 is evident even with an ambiguous N20 in patients with good outcome. Therefore, we evaluated the predictive value of P25/30 after cardiac arrest. DESIGN: A retrospective observational study. SETTING: University-affiliated hospital. SUBJECTS: Comatose survivors after out-of-hospital cardiac arrest treated by hypothermic targeted temperature management. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: The specificity and the positive predictive value of P25/30 and N20 in predicting poor outcome were the same, showing a rate of 100%. The sensitivity of P25/30 in predicting poor outcome (90.12% [95% CI, 81.5-95.6%]) was higher than that of N20 (70.37% [95% CI, 59.2-80%]). Also, the negative predictive value of P25/30 in predicting poor outcome (81.4% [95% CI, 69.4-89.4%]) was higher than that of N20 (59.3% [95% CI, 51-67.1%]). The P25/30-based adjusted model showed a larger area under the curve (0.98 [95% CI, 0.95-1]) compared with the N20-based adjusted model (0.95 [95% CI, 0.91-0.98]) (p = 0.02). CONCLUSIONS: The absence of P25/30 is related to poor outcome with a higher sensitivity, negative predictive value than the absence of N20.

BACKGROUND: Vancomycin-resistant enterococci (VRE) infections have become a major healthcare-associated pathogen problem worldwide. Nosocomial VRE infections could be effectively controlled by screening patients at high risk of harboring VRE and thereby lowering the influx of VRE into healthcare centers. In this study, we evaluated factors associated with VRE colonization in patients transferred to emergency departments, to detect patients at risk for VRE carriage. METHODS: This study was conducted in the emergency department of a medical college-affiliated hospital in Korea. Every patient transferred to the emergency department and admitted to the hospital from January to December 2016 was screened for VRE using rectal cultures. In this cross-sectional study, the dependent variable was VRE colonization and the independent variables were demographic and clinical factors of the patients and factors related to the transferring hospital. Patients were divided into two groups, VRE and non-VRE, and previously collected patient data were analyzed. Then we performed logistic regression analyses of characteristics that differed significantly between groups. RESULTS: Out of 650 patients, 106 (16.3%) had positive VRE culture results. Significant variables in the logistic analysis were transfer from geriatric long-term care hospital (adjusted odds ration [aOR]: 8.017; 95% confidence interval [CI]: 1.378-46.651), hospital days (4-7 days; aOR: 7.246; 95% CI: 3.229-16.261), duration of antimicrobial exposure (1-3 days; aOR: 1.976; 95% CI: 1.137-3.436), and age (aOR: 1.025; 95% CI: 1.007-1.043). CONCLUSION: VRE colonization in patients transferred to the emergency department is associated primarily with factors related to the transferred hospitals rather than demographic and clinical characteristics.

BACKGROUND: There are conflicting data regarding sex-based differences in the outcomes of out-of-hospital cardiac arrest (OHCA) patients, and whether the specific sex advantage is age-specific remains unclear. We assessed the impact of the interactions between sex and age on the neurological outcomes of OHCA patients receiving targeted temperature management (TTM). METHODS: Data collected from 2007 to 2012 for a multicenter, registry-based study of the Korean Hypothermia Network were analyzed. We used a multivariate logistic regression model with an interaction term (age × sex) as the final model for the outcomes. To evaluate the association between sex and outcome in specific age groups, all patients were divided into specific age subgroups, and the adjusted ORs and 95% CIs of good neurological outcomes for males were calculated for each age group. Finally, the ORs of a good neurological outcome for the specific age groups compared with the 50- to 59-year-old group were calculated for both sexes. RESULTS: In the interaction analysis, age was a negative prognostic factor (OR, 0.95 [95% CI, 0.93-0.98]), whereas sex was not associated with neurological outcomes (OR, 3.74 [95% CI, 0.85-16.35]), and reproductive age in females (age, < 50 years) was also not associated with good neurological outcomes. After the patients were divided into five age groups, sex was not an independent predictor of neurological outcomes across all age groups. Patients of both sexes aged < 40 years had significantly better outcomes than patients in the 50- to 59-year-old group (males, OR, 4.03 [95% CI, 1.86-8.73]; females, OR, 10.34 [95% CI, 1.99-53.85]). Males aged ≥ 70 years had significantly poorer neurological outcomes than those in the 50- to 59-year-old group (OR, 0.15 [95% CI, 0.07-0.32]), but this outcome was not observed for females (OR, 0.78 [95% CI, 0.20-3.14]). CONCLUSIONS: Sex did not influence the neurological outcomes of TTM-treated OHCA patients. In contrast to the outcomes in males, the neurological outcomes of females worsened from 18 to 59 years of age and then remained constant.

Fatal anaphylaxis is uncommon but not rare. Extrapolated mortality rates are 0.52% of total anaphylaxis patients Bock et al. (Jan. 2001) [1]. Nevertheless, compared with the incidence of the other cardiac arrest events, the incidence of cardiac arrest due to anaphylaxis is relatively small. As a result, the effect using targeted temperature management after anaphylaxis is not clearly understood. We report the case of a 63-year-old man who developed cardiac arrest after ingestion of two pieces of peach. He was resuscitated and his circulation returned spontaneously after approximately 11min of cardiopulmonary resuscitation, but he was unresponsive and had fixed dilated pupils. We initiated therapeutic hypothermia on the basis of protocol for 24h. The patient was gradually and successfully cooled and rewarmed. The patient opened his eyes spontaneously on day 5, obeyed commands on day 6, and was discharged on day 18. At the time of discharge, he had no neurologic deficiencies or other complications.

PURPOSE: The diagnostic value of the neutrophil-to-lymphocyte count ratio (NLR) and the Appendicitis Inflammatory Response (AIR) score for identifying acute appendicitis (AA) perforation in elderly patients in the emergency department (ED) were evaluated. METHODS: A total of 103 patients who were admitted for appendectomy for AA via the ED between January 2012 and December 2014 were reviewed retrospectively. Patients aged 65 and over were included. Patient age, sex, comorbidities, body temperature, clinical findings and initial laboratory results including white blood cell (WBC) count, NLR, serum levels of CRP and total bilirubin (TB) in the ED were assessed, and the AIR score was calculated. RESULTS: Perforation due to AA was identified in 58 (56.3 %) elderly patients. Median WBC count, neutrophil count, CRP and TB were significantly higher in the perforated group compared to the non-perforated group (p = 0.005, p = 0.001, p = 0.004 and p = 0.012) in the ED. The NLR was significantly different in the two groups (perforated vs non-perforated group, 9.5 vs 5.1, p < 0.001). The area under the curve value of NLR was 0.755 (95 % CI 0.660-0.834), and the cutoff value was 5.6 (sensitivity 78.0 % and specificity 65.9 %). In multivariate logistic analysis, NLR > 5.6 [odds ratio (OR) 6.794, p = 0.001] was significant independent factor for AA perforation in elderly patients. The AIR score risk probability did not differ between the two groups of elderly patients (p = 0.094). Twenty-five (42.4 %) patients in the perforated group and five (11.4 %) patients in the non-perforated group were classified as high probability by the modified AIR score including the NLR value (p = 0.001). CONCLUSION: We suggest that the initial NLR in the elderly patient is the most powerful predictive factor for the diagnosis of AA perforation in the ED.

BACKGROUND: Modern treatments have improved the survival rate following cardiac arrest, but prognostication remains a challenge. We examined the prognostic value of continuous electroencephalography according to time by performing amplitude-integrated electroencephalography on patients with cardiac arrest receiving therapeutic hypothermia. METHODS AND RESULTS: We prospectively studied 130 comatose patients treated with hypothermia from September 2010 to April 2013. We evaluated the time to normal trace (TTNT) as a neurological outcome predictor and determined the prognostic value of burst suppression and status epilepticus, with a particular focus on their time of occurrence. Fifty-five patients exhibited a cerebral performance category score of 1 to 2. The area under the curve for TTNT was 0.97 (95% confidence interval, 0.92-0.99), and the sensitivity and specificity of TTNT<24 hours after resuscitation as a threshold for predicting good neurological outcome were 94.6% (95% confidence interval, 84.9%-98.9%) and 90.7% (95% confidence interval, 81.7%-96.2%), respectively. The threshold displaying 100% specificity for predicting poor neurological outcome was TTNT>36 hours. Burst suppression and status epilepticus predicted poor neurological outcome (positive predictive value of 98.3% and 96.4%, respectively). The combination of these factors predicted a negative outcome at a median of 6.2 hours after resuscitation (sensitivity and specificity of 92.0% and 96.4%, respectively). CONCLUSIONS: A TTNT<24 hours was associated with good neurological outcome. The lack of normal trace development within 36 hours, status epilepticus, and burst suppression were predictors of poor outcome. The combination of these negative predictors may improve their prognostic performance at an earlier stage.

BACKGROUND: The mortality of patients with severe sepsis and septic shock is still high, and the prognosis of elderly patients tends to be particularly poor. Therefore, this study sought to conduct a comparative analysis of the abbreviated mortality in emergency department sepsis (abbMEDS) score, sequential organ failure assessment (SOFA) score, infection probability score (IPS), initial procalcitonin (PCT), and cytokine levels to investigate the effectiveness of each index in predicting the prognosis of elderly patients with sepsis in the emergency department (ED). METHODS: This was a single-center prospective study, and classified 55 patients (≥65 years of age) with systemic inflammatory response syndrome (SIRS) from January 2013 to December 2013 in the ED. A total of 36 elderly patients were diagnosed with sepsis. The prediction of prognosis using the prognostic scores (abbMEDS, SOFA, IPS) was analyzed. An early blood examination (WBC count, C-reactive protein, PCT, and cytokines) was conducted within the first 2 h of the patient's arrival at the ED. RESULTS: The median (IQR) age of subjects was 76.5 (70.5-81.5). After 28 days, 27 subjects (75 %) had survived, and 9 (25 %) had died. Fifteen (41.7 %) were sent to intensive care units (ICUs). The SOFA score and abbMEDS showed higher median (IQR) values of 9.5 (7.0-11.0) and 13.5 (12.0-15.0), respectively, in the ICU group than in the general ward group (p < 0.001). Analysis of the levels of PCT, IL-10, IL-6, and IL-5 had a significantly better ability to predict ICU admission (p = 0.001, p = 0.023, p = 0.030, p = 0.001). The prediction of mortality in the first 28 days via SOFA and the abbMEDS resulted in scores of 11.0 (8.0-11.0) and 14.0 (12.5-15.5) (p = 0.004, p = 0.003), respectively. However, levels of IPS, PCT, and cytokines did not show significant differences. CONCLUSIONS: In predicting ICU admission and the death of elderly sepsis patients in ED, SOFA and abbMEDS scores were effective. Of the various biomarkers, PCT, IL-10, IL-6, and IL-5 were effective in predicting ICU admission, but were not effective in predicting the death of elderly sepsis patients.

INTRODUCTION: Various methods and devices have been described for cooling after cardiac arrest, but the ideal cooling method remains unclear. The aim of this study was to compare the neurological outcomes, efficacies and adverse events of surface and endovascular cooling techniques in cardiac arrest patients. METHODS: We performed a multicenter, retrospective, registry-based study of adult cardiac arrest patients treated with therapeutic hypothermia presenting to 24 hospitals across South Korea from 2007 to 2012. We included patients who received therapeutic hypothermia using overall surface or endovascular cooling devices and compared the neurological outcomes, efficacies and adverse events of both cooling techniques. To adjust for differences in the baseline characteristics of each cooling method, we performed one-to-one matching by the propensity score. RESULTS: In total, 803 patients were included in the analysis. Of these patients, 559 underwent surface cooling, and the remaining 244 patients underwent endovascular cooling. In the unmatched cohort, a greater number of adverse events occurred in the surface cooling group. Surface cooling was significantly associated with a poor neurological outcome (cerebral performance category 3-5) at hospital discharge (p = 0.01). After propensity score matching, surface cooling was not associated with poor neurological outcome and hospital mortality [odds ratio (OR): 1.26, 95% confidence interval (CI): 0.81-1.96, p = 0.31 and OR: 0.85, 95% CI: 0.55-1.30, p = 0.44, respectively]. Although surface cooling was associated with an increased incidence of adverse events (such as overcooling, rebound hyperthermia, rewarming related hypoglycemia and hypotension) compared with endovascular cooling, these complications were not associated with surface cooling using hydrogel pads. CONCLUSIONS: In the overall matched cohort, no significant difference in neurological outcomes and hospital morality was observed between the surface and endovascular cooling methods.

INTRODUCTION: The aim of this study was to investigate the association of adverse events (AEs) during targeted temperature management (TTM) and other AEs and concomitant treatments during the advanced critical care period with poor neurological outcome at hospital discharge in adult out-of-hospital cardiac arrest (OHCA) patients. METHODS: This was a retrospective study using Korean Hypothermia Network registry data of adult OHCA patients treated with TTM in 24 teaching hospitals throughout South Korea from 2007 to 2012. Demographic characteristics, resuscitation and post-resuscitation variables, AEs, and concomitant treatments during TTM and the advanced critical care were collected. The primary outcome was poor neurological outcome, defined as a cerebral performance category (CPC) score of 3-5 at hospital discharge. The AEs and concomitant treatments were individually entered into the best multivariable predictive model of poor neurological outcome to evaluate the associations between each variable and outcome. RESULTS: A total of 930 patients, including 704 for whom a complete dataset of AEs and covariates was available for multivariable modeling, were included in the analysis; 476 of these patients exhibited poor neurological outcome [CPC 3 = 50 (7.1%), CPC 4 = 214 (30.4%), and CPC 5 = 212 (30.1%)]. Common AEs included hyperglycemia (45.6%), hypokalemia (31.3%), arrhythmia (21.3%) and hypotension (29%) during cooling, and hypotension (21.6%) during rewarming. Bleeding (5%) during TTM was a rare AE. Common AEs during the advanced critical care included pneumonia (39.6%), myoclonus (21.9%), seizures (21.7%) and hypoglycemia within 72 hours (23%). After adjusting for independent predictors of outcome, cooling- and rewarming-related AEs were not significantly associated with poor neurological outcome. However, sepsis, myoclonus, seizure, hypoglycemia within 72 hours and anticonvulsant use during the advanced critical care were associated with poor neurological outcome [adjusted odds ratios (95% confidence intervals) of 3.12 (1.40-6.97), 3.72 (1.93-7.16), 4.02 (2.04-7.91), 2.03 (1.09-3.78), and 1.69 (1.03-2.77), respectively]. Alternatively, neuromuscular blocker use was inversely associated with poor neurological outcome (0.48 [0.28-0.84]). CONCLUSIONS: Cooling- and rewarming-related AEs were not associated with poor neurological outcome at hospital discharge. Sepsis, myoclonus, seizure, hypoglycemia within 72 hours and anticonvulsant use during the advanced critical care period were associated with poor neurological outcome at hospital discharge in our study.
