RESUMEN
Objective@#It is difficult to predict medical outcomes for acute pyelonephritis (APN) in women. A delay in diagnosis and treatment results in rapid progression to circulatory collapse, multiple organ failure, and death. We investigated the value of procalcitonin (PCT) and neutrophil-to-lymphocyte ratio (NLR) in APN patients hospitalized through the emergency room. @*Methods@#We retrospectively evaluated women with APN presenting in the emergency room from January 2014 to May 2018. Inflammatory biomarkers, including PCT and NLR, were measured, and the severity of pyelonephritis was assessed using the Surviving Sepsis Campaign definitions (Sepsis-3). Multivariable logistic regression analysis was used to evaluate the risk factors associated with septic shock and the prediction for septic shock was compared using a receiver operating characteristic (ROC) curve. @*Results@#A total of 357 female patients with APN were included. The median level of PCT and NLR was higher in the septic shock group compared with other groups. Multivariate logistic regression analysis showed that age and PCT were risk factors for septic shock. When the ROC curve of septic shock was compared, PCT showed a higher area under the curve than NLR (NLR 0.65 vs. PCT 0.80). @*Conclusion@#The initial NLR in the emergency room showed significant differences depending on the severity as classified by Sepsis-3 definitions. However, NLR was not found to be associated with septic shock in female patients with APN.

RESUMEN
Objective@#Community-acquired pneumonia (CAP) in older patients is a potentially life-threatening infection with a poorprognosis. Therefore, is important to predict the mortality rate of CAP for older patients. This study examined the effectsof predictive increases on CAP mortality by adding a biomarker to known CAP severity prediction tools. @*Methods@#A retrospective analysis of information was conducted on patients older than 65 years, who were treated withCAP in five emergency departments from October 2016 to February 2017. The primary outcome was the 28-day mortality.The following were calculated for each patient: qSOFA (quick Sequential Organ Failure Assessment), A-DROP (Age,Dehydration, Respiratory failure, Orientation, blood Pressure), CURB-65 (Confusion, Urea level, Respiratory rate, Bloodpressure, age≥65 years), SMART-COP (Systolic blood pressure, Multilobar infiltrates, Albumin, Respiratory rate,Tachycardia, Confusion, Oxygen and pH), NLR (neutrophil:lymphocyte ratio), PLR (platelet:lymphocyte ratio), and CAR(high-sensitivity C-reactive protein:albumin ratio). The prognostic value for the 28-day mortality was determined by multivariatelogistic regression analysis. @*Results@#The 28-day mortality was 12.0% of 693 CAP patients. Multivariate logistic regression analysis showed that lactate(odds ratio [OR], 1.589; P<0.001) and CAR (OR, 1.208; P=0.006) were correlated with the 28-day mortality. NLR(OR, 1.00; P=0.983) and PLR (OR, 1.00; P=0.784) were not correlated. The area under curve (AUC) was significant asCAR 0.649, lactate 0.737, and SMART-COP 0.735 (P<0.001), and the AUC of lactate+SMART-COP increased significantlyto 0.784 compared to SMART-COP (P=0.014). @*Conclusion@#A combination of lactate and SMART-COP can be used as a tool to assess the severity of older hospitalizedCAP patients who visited emergency departments.
RESUMEN
OBJECTIVE: Despite increased survival in patients with cardiac arrest, it remains difficult to determine patient prognosis at the early stage. This study evaluated the prognosis of cardiac arrest patients using brain injury, inflammation, cardiovascular ischemic events, and coagulation/fibrinolysis markers collected 24, 48, and 72 hours after return of spontaneous circulation (ROSC).METHODS: From January 2011 to December 2016, we retrospectively observed patients who underwent therapeutic hypothermia. Blood samples were collected immediately and 24, 48, and 72 hours after ROSC. Neuron-specific enolase (NSE), S100-B protein, procalcitonin, troponin I, creatine kinase-MB, pro-brain natriuretic protein, D-dimer, fibrin degradation product, antithrombin-III, fibrinogen, and lactate levels were measured. Prognosis was evaluated using Glasgow-Pittsburgh cerebral performance categories and the predictive accuracy of each marker was evaluated. The secondary outcome was whether the presence of multiple markers improved prediction accuracy.RESULTS: A total of 102 patients were included in the study: 39 with good neurologic outcomes and 63 with poor neurologic outcomes. The mean NSE level of good outcomes measured 72 hours after ROSC was 18.50 ng/mL. The area under the curve calculated on receiver operating characteristic analysis was 0.92, which showed the best predictive power among all markers included in the study analysis. The relative integrated discrimination improvement and category-free net reclassification improvement models showed no improvement in prognostic value when combined with all other markers and NSE (72 hours).CONCLUSION: Although biomarker combinations did not improve prognostic accuracy, NSE (72 hours) showed the best predictive power for neurological prognosis in patients who received therapeutic hypothermia.

OBJECTIVE@#The purpose of this study was to test the hypothesis that an increase in the neutrophil-to-lymphocyte ratio (NLR) increases the risk of in-hospital density in patients aged 65 and older, who are hospitalized in intensive care through the emergency rooms.@*METHODS@#A retrospective medical record study was conducted on elderly patients who were admitted to intensive care units via the emergency room. The exclusion criteria were data loss, intensive care unit reentry, cerebrovascular accidents, hematologic disease, and trauma cases.@*RESULTS@#The study included 526 patients; the mean age was 79, and 261 (49.6%) were male. The in-hospital mortality was 18.4% (97 patients). The initial NLR was higher in the non-survivor group than the survivor group, but the difference was not statistically significant (9.82±11.02 vs. 11.48±6.11, P=0.080). In multivariate logistic analysis, the initial NLR had no statistical significance, and the odd ratio was increased from one day later. Comparing the receiver operating characteristic curve of the NLR and Acute Physiology and Chronic Health Evaluation II (APACHE II) and Simplified Acute Physiology Score II (SAPS II) scores, the NLR showed an increase in the area of under curve (AUC) value over time as well as the highest AUC with the SAPS II scores.@*CONCLUSION@#In elderly adults, early NLR was found to have weak power to predict in-hospital mortality. Over time, the NLR values more than two days after intensive care unit admission may be useful in predicting the in-hospital mortality for older patients. This may be due to the delay in the immune response and the complex medical history.
RESUMEN
OBJECTIVE: As aging progresses, clinical characteristics of elderly patients in the emergency department (ED) vary by age. We aimed to study differences among elderly patients in the ED by age group. METHODS: For 2 years, patients aged 65 and older were enrolled in the study and classified into three groups: youngest-old, ages 65 to 74 years; middle-old, 75 to 84 years; and oldest-old, ≥85 years. Participants’ sex, reason for ED visit, transfer from another hospital, results of treatment, type of admission, admission department and length of stay were recorded. RESULTS: During the study period, a total 64,287 patients visited the ED; 11,236 (17.5%) were aged 65 and older, of whom 14.4% were 85 and older. With increased age, the female ratio (51.5% vs. 54.9% vs. 69.1%, P < 0.001), medical causes (79.5% vs. 81.3% vs. 81.7%, P=0.045), and admission rate (35.3% vs. 42.8% vs. 48.5%, P < 0.001) increased. Admissions to internal medicine (57.5% vs. 59.3% vs. 64.7%, P < 0.001) and orthopedic surgery (8.5% vs. 11.6% vs. 13.8%, P < 0.001) also increased. The ratio of admission to intensive care unit showed no statistical significance (P=0.545). Patients over age 85 years had longer stays in the ED (330.9 vs. 378.9 vs. 407.2 minutes, P < 0.001), were discharged home less (84.4% vs. 78.9% vs. 71.5%, P < 0.001), and died more frequently (6.3% vs. 10.4% vs. 13.0%, P < 0.001). CONCLUSION: With increased age, the proportion of female patients and medical causes increased. Rates of admission and death increased with age and older patients had longer ED and hospital stays.

PURPOSE: To determine adequacy of brightness and proper brightness of the direct laryngoscope in emergency departments. METHODS: We investigated blade and handle in 26 hospitals in Seoul and made 110 combination. We excluded malfunction and non-fixed combination, and measured the lux of each combination. We divided results into two groups (bulb type and fiber type) in two ways (adult type and pediatric type). RESULTS: In the 110 combinations, the median lux value was 836.25. The number of laryngoscopes in which brightness exceeded International Organization for Standardization (ISO) recommended value of the 700 was 67. There was no statistically significant difference in median lux between fiber type and bulb type (847.5 vs 802.0; p=0.870), while the brightness of the pediatric type was brighter than the adult type. A questionnaire of laryngoscope management revealed no regular basis of use, and complete absence of awareness of brightness criteria. CONCLUSION: An improved laryngoscope managing system is essential including regular criteria for laryngoscope management.
