RESUMO
PURPOSE: To verify the role of lactate dehydrogenase to albumin (LDH/ALB) ratio as an independent prognostic factor for mortality due to the lower respiratory tract infection (LRTI) in the emergency department (ED). METHODS: We reviewed the electronic medical records of patients who were admitted to the ED for the management of LRTI between January 2018 and December 2020. Initial vital signs, laboratory data, and patient severity scores in the ED were collected. The LDH/ALB ratio was compared to other albumin-based ratios (blood urea nitrogen to albumin ratio, C-reactive protein to albumin ratio, and lactate to albumin ratio) and severity scales (pneumonia severity index, modified early warning score, CURB-65 scores), which are being used as prognostic factors for in-hospital mortality. Multivariable logistic regression was performed to identify independent risk factors. RESULTS: The LDH/ALB ratio was higher in the non-survivor group than in the survivor group (median [interquartile range]: 217.6 [160.3;312.0] vs. 126.4 [100.3;165.1], p < 0.001). In the comparison of the area under the receiver operating characteristic curve (AUC) for predicting in-hospital mortality, the AUC of the LDH/ALB ratio (0.808, 95% confidence interval: 0.757-0.842, p < 0.001) was wider than other albumin-based ratios and severity scales, except the blood urea nitrogen to albumin ratio. In the multivariable logistic regression analysis, the LDH/ALB ratio independently affected in-hospital mortality. CONCLUSION: The LDH/ALB ratio may serve as an independent prognostic factor for in-hospital mortality in patients with LRTI.

PURPOSE: This study aimed to determine whether the blood urea nitrogen to serum albumin (B/A) ratio is a useful prognostic factor of mortality in patients with aspiration pneumonia. METHODS: The study included patients with aspiration pneumonia who had been admitted to our hospital via the emergency department (ED) between January 1, 2014 and December 31, 2018. The 28-day mortality after the ED visits was the primary end point of this study. The data of the survivors and non-survivors were compared. RESULTS: A final diagnosis of aspiration pneumonia was made for 443 patients during the study period. Significant differences were observed in age, respiratory rate, albumin levels, total protein levels, blood urea nitrogen levels, C-reactive protein levels, glucose, and Charlson comorbidity index scores between the survivor and non-survivor groups. Moreover, the B/A ratio was significantly higher in the non-survivor group than that in the survivor group. The area under the curve for the B/A ratio was 0.70 [95% confidence interval (CI) 0.65-0.74], 0.71 for the PSI (95% CI 0.67-0.76), 0.64 for CURB-65 (95% CI 0.60-0.69), and 0.65 for albumin (95% CI 0.60-0.70) on the receiver operating characteristic curve for predicting mortality within 28 days of the ED visit. Multivariable logistic regression analysis revealed that the B/A ratio (>7, OR 3.40, 95% CI 1.87-6.21, P < 0.001) was associated with mortality within 28 days of the ED visit. CONCLUSION: The B/A ratio is a simple and potentially useful prognostic factor of mortality in aspiration pneumonia patients.

BACKGROUND: This study analyzed the characteristics of hydrogen fluoride-exposed patients (HFEPs) treated in the emergency department (ED) of a local university hospital, and reviewed the hospital's disaster response according to space, staff, supplies, and systems (4Ss). METHODS: This retrospective observational chart review and descriptive study included 199 HFEPs among 2588 total ED patients who visited a local university emergency medical center for treatment between September 27, 2012 and October 20, 2012, following a hydrofluoric acid leak at the Hube Globe factory in Gumi City, Republic of Korea. Descriptive results concerning the 4Ss were obtained by interviewing ED specialist staff physicians on duty during the study period. In accordance with American Burn Association criteria, patients requiring burn center referral were assigned to the major burn group (MBG) as severe condition. RESULTS: During the acute phase (within 8 h after leak initiation), there were 43 patients in the ED, which was staffed with 3 doctors and 3 nurses, without 4S resources. Of these 43 patients, there were 8 HFEPs (100%) in the MBG and 0 in the non-MBG (NMBG). During the subacute phase (24 h after the acute phase), there were 262 patients in the ED including 167 HFEPs, of whom 45 (26.95%) were in the MBG and 122 (73.05%) were in the NMBG. The ED was then staffed with 6 doctors (3 on day shift and 3 on night shift) and 10 nurses (3 on day shift, 4 on evening shift, and 3 on night shift), and no 4S resources were available. Throughout the study period, no 4Ss were available. First, there was no expansion of ED space or secured disaster reserve beds. Second, there was no increase in manpower with duty time adjustments or duty relocation for ED working personnel. Third, there was no logistics reinforcement (e.g., antidote or personal protective equipment). Fourth, there were no disaster-related measures for the administration department, decontamination zone setup, safety diagnostic testing, or designated disaster triage implementation. CONCLUSIONS: The hospital's disaster response was insufficient for all aspects of the 4Ss. Detailed guidance concerning a hospital disaster management plan is required.

PURPOSE: We evaluated whether combining the serum albumin level and the Prediction Rule for Admission policy in Complicated urinary Tract InfeCtion LEiden (PRACTICE) class could be a prognostic predictor in elderly patients with urinary tract infection (UTI). METHODS: We retrospectively included adult patients (age ≥ 65 years) with UTI who were hospitalized in the emergency department (ED) between January 1, 2014 and December 31, 2018. We graded the serum albumin level and classified the PRACTICE score; the modified PRACTICE was defined as the sum of the albumin level grade and the PRACTICE class. We comparatively assessed the predictive value for in-hospital mortality and admission to the intensive care unit (ICU) in survivor and non-survivor groups. RESULTS: In total, the study analysis included 1159 patients, and in-hospital mortality was 3.4% (n = 39). The modified PRACTICE score (4.0 [1.4] vs 6.1 [1.2], p < 0.001) was significantly increased in the non-survivor group. The area under the curve value of factors associated with in-hospital mortality were the Modified Early Warning Score (MEWS) 0.57 (95% CI 0.54-0.60), albumin 0.83 (95% CI 0.81-0.85), PRACTICE 0.71 (95% CI 0.69-0.74), and the modified PRACTICE 0.86 (95% CI 0.84-0.88). Factors associated with ICU admission were MEWS 0.65 (95% CI 0.62-0.68), albumin 0.66 (95% CI 0.64-0.69), PRACTICE 0.66 (95% CI 0.63-0.68), and the modified PRACTICE 0.72 (95% CI 0.69-0.74). CONCLUSION: The modified PRACTICE score can be a useful prognostic predictor in elderly patients with UTI.

BACKGROUND: Serum interleukin-6 (IL-6) is a cytokine released in response to an inflammatory stimulus or tissue injury. IL-6 levels are known to increase in patients with brain injury. OBJECTIVE: We investigated the neurologic outcomes associated with serum IL-6 levels in out-of-hospital cardiac arrest (OHCA) survivors who underwent target temperature management (TTM). METHODS: This was a prospective single-center observational study from October 2018 to November 2019 in a cohort of 45 patients. Serum inflammatory markers (IL-6, C-reactive protein, white blood cells) were determined in samples obtained immediately and at 24, 48, and 72 h after the return of spontaneous circulation (ROSC). Poor neurologic outcome, defined as Cerebral Performance Category 3-5 at 3 months after cardiac arrest, was the primary outcome. RESULTS: Among 45 patients enrolled in this study, 25 (55.6%) patients showed a poor neurologic outcome. IL-6 levels were significantly higher in the poor neurologic outcome group immediately (IL-60) after ROSC. The area under the curve (AUC) value of IL-60 was the highest among those of serum IL-6, CRP, and WBC at each time point. The IL-6 levels for predicting poor neurologic outcome had a sensitivity of 75.0%, with 80% specificity at IL-60. The AUC of IL-60 was 0.810 (95% confidence interval 0.664-0.913), with a cutoff value of 346.7 pg mL-1. CONCLUSIONS: Serum IL-6 level immediately after ROSC was a highly specific and sensitive marker for the 3-month poor neurologic outcome, and may be a useful early predictive marker of neurologic outcome in OHCA survivors treated with TTM.

AIM OF THE STUDY: No definitive experimental or clinical evidence exists whether brain hypothermia before, rather than during or after, resuscitation can reduce hypoxic-ischemic brain injury following cardiac arrest/cardiopulmonary resuscitation (CA/CPR) and improve outcomes. We examined the effects of moderate brain hypothermia before resuscitation on survival and histopathological and neurobehavioral outcomes in a mouse model. METHODS: Adult C57BL/6 male mice (age: 8-12â¯weeks) were subjected to 8-min CA followed by CPR. The animals were randomly divided into sham, normothermia (NT; brain temperature 37.5⯰C), and extracranial hypothermia (HT; brain temperature 28-32⯰C) groups. The hippocampal CA1 was assessed 7â¯day after resuscitation by histochemical staining. Neurobehavioral outcomes were evaluated by the Barnes maze (BMT), openfield (OFT), rotarod, and light/dark (LDT) tests. Cleaved caspase-3 and heat shock protein 60 (HSP70) levels were investigated by western blotting. RESULTS: The HT group exhibited higher survival and lower CA1 neuronal injury than did the NT group. HT mice showed improved spatial memory in the BMT compared with NT mice. NT mice travelled a shorter distance in the OFT and tended to spend more time in the light compartment in the LDT than did sham and HT mice. The levels of cleaved caspase-3 and HSP70 were non-significantly higher in the NT than in the sham and HT groups. CONCLUSIONS: Moderate brain hypothermia before resuscitation improved survival and reduced histological neuronal injury, spatial memory impairment, and anxiety-like behaviours after CA/CPR in mice.

PURPOSE: The technical factors which improve cosmetic outcomes and which need to be emphasized in education of junior residents have yet to be described. We compared cases in which suturing was performed by either junior emergency medicine residents or experts, in order to determine the focus of future education and training. METHODS: Wound registry data was reviewed and retrospectively analyzed from September 2015 to February 2016. Only patients who visited the emergency room with facial lacerations were enrolled, and their wound registry data sheets were reviewed. Practitioners were divided into junior resident and expert groups. We assessed the progress using the Stony Brook Scar Evaluation Scale (SBSES) 5-10â¯days following suturing. RESULTS: Sixty-six patients were enrolled; 43 (65.2%) were men. The median (interquartile range) cosmetic scores (SBSES scale) for suturing performed by junior residents or experts were 3 (2-4) and 5 (4-5), respectively (pâ¯=â¯0.001). The percentage of maximum scores for each SBSES category was significantly lower in the junior resident group than in the expert group for width (68% vs. 86%), hatch marks (68% vs. 93%), and overall appearance (41% vs. 80%) (all pâ¯<â¯0.001). CONCLUSIONS: There were significant differences in scar widths and hatch marks, which were attributable to the skill level of the practitioner who performed the suturing of facial lacerations. Junior residents should be educated about maintenance of proper tension, atraumatic technique, and performing appropriate trimming or debridement.

BACKGROUND: Metformin is commonly used for the treatment of type 2 diabetes mellitus. Renal insufficiency is one of the contraindications for its use. Inadvertent prescription in patients with renal insufficiency may lead to metformin-associated lactic acidosis (MALA), which is associated with a high risk of mortality. Consequently, the early recognition and management of MALA is essential. CASE REPORT: We present the case of a 68-year-old man who had reversible blindness resulting from severe lactic acidosis. On presentation, he was alert, oriented, and had no complaints except mild abdominal discomfort and blindness. He denied any history of trauma or drug abuse. The results of the laboratory studies showed severe metabolic acidosis with a high anion gap and increased levels of serum creatinine. There were no predisposing ocular or neurologic lesions that could have induced the blindness. Although the blood levels of methanol, ethanol, and metformin were not estimated, correction of acidosis and hemodialysis led to a complete recovery. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Rarely, transient blindness may occur in patients with fatal severe metabolic acidosis. Evaluation for the presence of metabolic acidosis and a detailed medical history are essential in the management of acute blindness in such patients.

BACKGROUND: The ability to correct unnatural-appearing, high, and deep double eyelid folds has been limited by the lack of redundant upper eyelid skin and the presence of prior incision line scars in patients. METHODS: From January 2000 to September 2011, 256 patients with high and deep double eyelid folds underwent our fold-lowering procedure. The first dissection was made at the superficial layer between the orbicularis oculi muscle and orbital septum/retroorbicularis oculi fat. The second dissection was at a deeper layer between the preaponeurotic fat and levator aponeurosis. The dissection proceeded 7 to 8 mm farther cephalad to the prior fold line to separate the upper flap and the floor from the prior fold line. The lower flap was undermined caudally to obtain normal skin tension, and the lower flap was secured to the septoaponeurosis junctional thickening or pretarsal tissue. Six months after surgery, the correction of the high fold scar and change in fold height (with eyes closed) was documented. RESULTS: Using the authors' technique, unnatural-appearing, high, and deep double eyelid folds were converted to lower nondepressed folds. Although prior high fold incision scars could be seen postoperatively on close examination, they were not easily visible. Complications included fold height asymmetry in 10 cases, persistence of the prior fold in 5 cases, and redundant upper flap skin that needed further excision in 25 cases. CONCLUSIONS: Using a wide double-layer dissection, high folds were lowered successfully even in situations where there was no redundant upper eyelid skin for excision.

Efforts are ongoing to enhance the functionality of human acellular dermal matrices (hADMs), which are extensively utilized in reconstructive surgeries. Among these efforts, plasma treatments, particularly vacuum plasma treatments, have recently emerged in the medical field. This study aims to investigate the efficacy of a vacuum plasma treatment in enhancing the biocompatibility and biointegration of hADMs. Utilizing a plasma activator (ACTILINK reborn, Plasmapp Co., Ltd., Daejeon, Republic of Korea), hADMs were treated and evaluated through in vitro and in vivo analyses. Hydrophilicity changes were gauged by the blood absorption times, while SEM imaging was used to analyze physical surface deformation. Protein adsorption was measured with fluorescently labeled bovine serum albumin and fibronectin. For the in vivo study, mice were implanted with plasma-treated and untreated hADMs, and the post-implantation effects were analyzed through histological and immunofluorescence microscopy. The plasma-treated hADMs demonstrated a significantly enhanced hydrophilicity compared to the untreated samples. SEM imaging confirmed the maintenance of the microroughness after the treatment. The treated hADMs showed a significant reduction in fibronectin adsorption, a critical factor for cellular adhesion. In vivo, the plasma-treated hADMs exhibited reduced capsule formation and enhanced fibroblast infiltration, indicating improved biocompatibility and integration. These findings highlight the potential of a plasma treatment to enhance the performance of hADMs in clinical settings, offering a promising avenue for improving reconstructive surgery outcomes.
RESUMO
Object: Effective triage of febrile patients in the emergency department is crucial during times of overcrowding to prioritize care and allocate resources, especially during pandemics. However, available triage tools often require laboratory data and lack accuracy. We aimed to develop a simple and accurate triage tool for febrile patients by modifying the qSOFA score. Methods: We retrospectively analyzed data from 7,303 febrile patients and created modified versions of qSOFA using factors identified through multivariable analysis. The performance of these modified qSOFAs in predicting in hospital mortality and intensive care unit (ICU) admission was compared using the area under the receiver operating characteristic curve (AUROC). Results: Through multivariable analysis, the identified factors were age (A), male sex (M), SpO2 (S), and lactate levels (L). The AUROCs of ASqSOFA (for in-hospital mortality: 0.812; 95% CI: 0.789-0.835, for ICU admission: 0.794; 95% CI: 0.771-0.817), which included age and SpO2 with qSOFA, were simple and not inferior to other more complex models (e.g., ASMqSOFA, ASLqSOFA, and ASMLqSOFA). ASqSOFA also displayed significantly higher AUROC than other triage scales, such as the modified early warning score and Korean triage and acuity scale. The optimal cut-off score of ASqSOFA for the outcome was 2 and the score for redistribution to a lower-level emergency department was 0. Conclusion: We demonstrated that ASqSOFA can be employed as a simple and efficient triage tool for emergency febrile patients to aid in resource distribution during overcrowding. It may also be applicable in pre-hospital settings for febrile patient triage.
RESUMO
BACKGROUND: No standard treatment guidelines have been established for postpartum hemorrhage (PPH). We aimed to assess the differences in outcomes and prognoses between patients with PPH who underwent surgical and non-surgical treatment. METHODS: This retrospective study included 230 patients diagnosed with PPH at two referral hospitals between August 2013 and October 2023. The patients were divided into non-surgical (group 1, n = 159) and surgical intervention groups (group 2, n = 71). A subgroup analysis was performed by dividing the surgical intervention group into immediate (n = 45) and delayed surgical intervention groups (n = 26). RESULTS: Initial lactic acid levels and shock index were significantly higher in group 2 (2.85 ± 1.37 vs. 4.54 ± 3.63 mmol/L, p = 0.001, and 0.83 ± 0.26 vs. 1.10 ± 0.51, p < 0.001, respectively). Conversely, initial heart rate and body temperature were significantly lower in group 2 (92.5 ± 21.0 vs. 109.0 ± 28.1 beat/min, p < 0.001, and 37.3 ± 0.8 °C vs. 37.0 ± 0.9 °C, p = 0.011, respectively). Logistic regression analysis identified low initial body temperature, high lactic acid level, and shock index as independent predictors of surgical intervention (p = 0.029, p = 0.027, and p = 0.049, respectively). Regarding the causes of PPH, tone was significantly more prevalent in group 1 (57.2% vs. 35.2%, p = 0.002), whereas trauma was significantly more prevalent in group 2 (24.5% vs. 39.4%, p = 0.030). Group 2 had worse overall outcomes and prognoses than group 1. The subgroup analysis showed significantly higher rates of uterine atony combined with other causes, hysterectomy, and disseminated intravascular coagulopathy in the delayed surgical intervention group than the immediate surgical intervention group (42.2% vs. 69.2%, p = 0.027; 51.1% vs. 73.1%, p = 0.049; and 17.8% vs. 46.2%, p = 0.018, respectively). CONCLUSIONS: Patients with PPH presenting with increased lactic acid levels and shock index and decreased body temperature may be surgical candidates. Additionally, immediate surgical intervention in patients with uterine atony combined with other causes of PPH could improve prognosis and reduce postoperative complications.

BACKGROUND: Point-of-Care Ultrasound (POCUS) is a quick, useful, noninvasive, and inexpensive diagnostic tool used for the diagnosis of trauma, abdominal pain, dyspnea, and chest pain in the emergency department (ED). However, the diagnostic accuracy of ultrasound in the ED may be different from those reported in previous studies owing to the setting and time constraints in ED. METHODS: We conducted our study in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. A literature search was conducted using databases on US National Library of Medicine's database of biomedical literature, Ovid MEDLINE, online database of biomedical articles, and the collection of databases of systematic reviews and other evidence. The inclusion criteria were the use of bedside ultrasound as a diagnostic tool for acute appendicitis in the ED and the available data on diagnostic parameters such as sensitivity, specificity, and positive and negative predictive values (NPV). We constructed forest plots and summary receiver operating characteristic curves to evaluate the diagnostic accuracy of bedside ultrasound for acute appendicitis in the ED. RESULTS: A total of 21 studies that met the inclusion criteria of this study were included for analysis. The overall pooled sensitivity was 0.81 (95% CI, 0.78-0.83), whereas the pooled specificity was 0.87 (95% CI, 0.85-0.88). However, the I2 test showed 91.7% and 90.9% heterogeneity in the sensitivity and specificity values, respectively. The summary receiver operating characteristic curves showed high levels of accuracy, as evidenced by an area under the curve of 0.9249 (standard error: 0.0180). CONCLUSIONS: The use of ultrasound for the diagnosis of acute appendicitis in the ED showed that ultrasound has high overall sensitivity and specificity for the diagnosis of acute appendicitis. however, high heterogeneity among the included studies was observed.

OBJECTIVE: We evaluated the utility of the Korean Modified Early Warning Score (KMEWS), which combines the Modified Early Warning Score (MEWS) and the Korean Triage and Acuity Scale (KTAS), as a triage tool to screen for infection in patients who visit the emergency department. METHODS: We retrospectively reviewed data extracted from electronic medical records. Patients aged ≥18 years with an infection who were admitted to the hospital via the emergency department between January 2018 and December 2019 were eligible for inclusion. The KMEWS score was calculated as the sum of the KTAS level and the MEWS score. We generated receiver operating characteristic curves and determined the area under the receiver operating characteristic curve (AUC) for the KMEWS, KTAS, MEWS, and Mortality in Emergency Department Sepsis (MEDS) scales. The primary outcome was septic shock, and secondary outcomes were intensive care unit admission and in-hospital mortality. RESULTS: The AUC values (95% confidence interval) for predicting septic shock were as follows: KMEWS, 0.910 (0.902-0.918); MEWS, 0.896 (0.887-0.904); KTAS score, 0.809 (0.798-0.819); and MEDS, 0.927 (0.919-0.934). The AUC values (95% confidence interval) for predicting in-hospital mortality were as follows: KMEWS, 0.752 (0.740-0.764); MEWS, 0.717 (0.704-0.729); KTAS score, 0.764 (0.752-0.776); and MEDS, 0.844 (0.834-0.854). The AUC values (95% confidence interval) for predicting intensive care unit admission were as follows: KMEWS, 0.826 (0.816-0.837); MEWS, 0.782 (0.770-0.793); KTAS score, 0.821 (0.810-0.831); and MEDS, 0.839 (0.829-0.849). CONCLUSION: The KMEWS, which is a combination of the MEWS and the KTAS scores, might be a useful triage tool in emergency department patients who present with infection, particularly for predicting septic shock.
RESUMO
PURPOSE: Urine output (UO) is an important intraoperative parameter that is not yet electronically monitored. We compared an automatic urinometer (AU) based on a smart scale with a manual urinometer (MU). PATIENTS AND METHODS: This prospective study investigated the hourly UO of 35 preoperative patients with an indwelling urinary catheter using AU, MU, and cylinder measurements. Data were analyzed using the Bland-Altman method. A questionnaire related to the use of the AU was completed by medical staff (n=25). RESULTS: Compared to the cylinder measurements, the differences in measurements by the AU and the MU were -6.31 â± â15.03 âmL/h (p=0.018) and 20.26 â± â26.81 âmL/h (p=0.001), respectively. The r values for the comparison of cylinder measurements with AU and MU values were 0.985 (p<0.001) and 0.968 (p<0.001), respectively. Bland-Altman analyses showed that cylinder measurements had better agreement with the AU measurements than with the MU measurements. Also, the medical staff reported that the use of the AU was easier to learn than the use of the MU (p<0.001). CONCLUSIONS: Compared to the MU values, AU values were noninferior; they had significantly less bias and temporal deviation. Additionally, the medical staff reported that the use of the AU was easier to learn than the use of the MU.

Surgical debridement is an essential step in treating complex facial lacerations (CFL). As the CFL severity increases, conventional surgical debridement (CSD) of wound edges becomes difficult and may be insufficient. Because the severity and shape of each CFL vary, it is necessary to tailor the customized pre-excisional design, that is, tailored surgical debridement (TSD), for each case before performing surgical debridement. The use of TSD can enable effective debridement of CFL with higher severity. This study aimed to compare the cosmetic outcomes and complication incidence of CSD versus TSD according to CFL severity. In this retrospective observational study, eligible patients with CFL who visited the emergency department between August 2020 and December 2021 were examined. CFL severity was graded as Grades I and II. The outcomes of CSD and TSD were compared using the scar cosmesis assessment and rating (SCAR) scale, wherein a good cosmetic outcome was defined as a SCAR score ofâ ≤â 2. The percentage of good cosmetic outcomes between the 2 groups was compared. The SCAR score and percentage of good cosmetic outcomes between the 2 groups were compared overall and by severity. For analyzing complication incidence, asymmetry, infection, and dehiscence incidence were compared. In total, 252 patients were enrolled [121 (48.0%) CSD and 131 (52.0%) TSD]. The median SCAR scores were 3 (1-5) and 1 (0-2) in all enrolled patients (Pâ <â .001), 2 (0-4), and 1 (0-1) in Grade I patients (Pâ <â .01), and 5 (4-6) and 1 (1-2) in Grade II patients (Pâ <â .001) in the CSD and TSD groups, respectively. The percentage of good cosmetic outcomes was 46.3% and 84.0% overall (Pâ <â .001), 59.6% and 85.0% in Grade I patients (Pâ <â .01), and 9.4% and 83.5% in Grade II patients (Pâ <â .001) in the CSD and TSD groups, respectively. The incidence of complications was significantly higher in the CSD group than in the TSD group, but this was limited to asymmetry. No significant difference was noted in infection or dehiscence. Compared with CSD, TSD can lead to an objectively good cosmetic prognosis at higher CFL severity and can reduce facial asymmetry occurrence.

This study conducted to analyze and compare the epidemiological and clinical characteristics of hydrogen fluoride-exposed patients based on major burn criteria for the appropriate emergency department (ED) response to a mass casualty chemical spill. This retrospective cross-sectional study included the records of patients (n = 199) who visited the ED of Gumi City University Hospital from September 27, 2012, to October 20, 2012. Subjects were included in the major burn group (MBG) if they presented with wounds that required referral to a burn center according to the American Burn Association guidelines or in the nonmajor burn group (NMBG) if not. Males were predominant in both the MBG (n = 55, 48 males) and NMBG (n = 144, 84 males; P < .05). The most prevalent timeline for visiting the ED was the phase which included 9-32 hours post-leak of hydrogen fluoride, including 45 patients (81.8%) in the MBG and 122 patients (84.7%) in the NMBG (P < .001). The respiratory tract was the site of greatest damage in patients in both the MBG and NMBG (n = 47, 85.5% vs n = 142, 98.6%, P < .001). Regarding dispositions, all patients in the NMBG were discharged (n = 144, 100%); however, eight patients (14.5%) in the MBG underwent other dispositions (discharge against medical advice, five patients; admission, one patient; death, two patients, P < .05). Patient outcomes after major chemical contamination events should be characterized in future studies to maximize the quality of patient care.

BACKGROUND: Rapid disease progression in neuroemergencies is associated with blood-brain barrier (BBB) disruption. We investigated a less invasive strategy for assessing BBB status by evaluating S100 calcium-binding protein B (S100B) and neuron-specific enolase (NSE) at early stages of the hypoxic-ischemic brain injury (HIBI) cascade. METHODS: This retrospective study used prospectively collected data from patients with out-of-hospital cardiac arrest (August 2019-July 2021). Albumin specimens obtained from serum and cerebrospinal fluid via arterial catheter and lumbar puncture were used to measure the albumin quotient (Qa), which is widely accepted as the gold standard method for detecting BBB disruption. Serum S100B and NSE levels were measured simultaneously following the return of spontaneous circulation. We conducted linear regression to evaluate the relationship between S100B and Qa and the predictive performance of S100B for abnormal Qa. The primary study outcome was abnormal Qa (>0.007). RESULTS: Forty-one patients were enrolled; 30 showed an abnormal Qa suggestive of BBB disruption. S100B levels were significantly higher than in those with a normal Qa (0.244 µg/L [interquartile range [IQR], 0.146-0.823 vs 0.754 µg/L [IQR, 0.317-2.228], P = .03). We report a positive correlation between serum S100B and Qa (R2 = 0.110; P = .04). The area under the receiver operating characteristics curve (AUROC) evaluating the predictive performance of S100B with respect to abnormal Qa was 0.718 (95% confidence interval, 0.556-0.847). The cutoff value for S100B (with respect to BBB disruption) in the total cohort was 0.283 µg/L (sensitivity, 80.0%; specificity, 72.7%). Subgroup analyses in patients with serum neuron-specific enolase (NSE) levels of <40.8 ng/mL (excluding those with established neuronal cell injury) showed an improved correlation coefficient (R2 = 0.382; P < .01) and predictive performance (AUROC, 0.836 [95% confidence interval, 0.629-0.954]) compared with the total cohort. CONCLUSIONS: Serum S100B obtained at an early stage of the HIBI cascade is associated with abnormal Qa, suggesting BBB disruption. The predictive performance of S100B and the correlation between serum S100B and Qa can be improved using a complementary strategy (i.e., evaluations of S100B and NSE levels) that combines considerations of cell damage in astrocytes and neurons.
