BACKGROUND: The prevalence and prognostic value of overt disseminated intravascular coagulation (DIC) in patients with septic shock presenting to emergency departments (EDs) is poorly understood, particularly following the release of a new definition of septic shock. The purpose of this study was to investigate the prevalence and prognostic value of DIC in septic shock. METHODS: We performed retrospective review of 391 consecutive patients with septic shock admitting to the ED of tertiary care, university-affiliated hospital during a 16-month. Septic shock was defined as fluid-unresponsive hypotension requiring vasopressor to maintain a mean arterial pressure of 65 mmHg or greater, and serum lactate level ≥ 2 mmol/L. Overt DIC was defined as an International Society on Thrombosis and Hemostasis (ISTH) score ≥ 5 points. The primary endpoint was 28-day mortality. RESULTS: Of 391 patients with septic shock, 290 were included in the present study. The mean age was 65.6 years, the 28-day mortality rate was 26.9%, and the prevalence of overt DIC was 17.6% (n = 51) according to the ISTH score. The median DIC score was higher in non-survivors than in survivors (5.0 vs. 2.0, p = 0.001). Significant higher risk of mortality was observed in overt DIC patients compared to those without (28.2% vs. 13.7%, p = 0.005). Multivariable logistic regression analysis identified DIC to be independently associated with 28-day mortality (odds ratio, 2.689 [95% confidence interval, 1.390-5.201]). CONCLUSIONS: Using the ISTH criteria of DIC, overt DIC in septic shock was found to be common among patients admitting to the ED and to be associated with higher mortality when it is accompanied with septic shock. Efforts are required to identify presence of overt DIC during the initial treatment of septic shock in patients presenting the the ED.

We performed this study to examine lifestyle patterns and dietary behavior based on the level of Internet addiction of Korean adolescents. Data were collected from 853 Korean junior high school students. The level of Internet addiction was determined based on the Korean Internet addiction self-scale short form for youth, and students were classified as high-risk Internet users, potential-risk Internet users, and no risk Internet users. The associations between the students' levels of Internet addiction and lifestyle patterns and dietary behavior were analyzed using a chi-square test. Irregular bedtimes and the use of alcohol and tobacco were higher in high-risk Internet users than no risk Internet users. Moreover, in high-risk Internet users, irregular dietary behavior due to the loss of appetite, a high frequency of skipping meals, and snacking might cause imbalances in nutritional intake. Diet quality in high-risk Internet users was also worse than in potential-risk Internet users and no risk Internet users. We demonstrated in this study that high-risk Internet users have inappropriate dietary behavior and poor diet quality, which could result in stunted growth and development. Therefore, nutrition education targeting high-risk Internet users should be conducted to ensure proper growth and development.

BACKGROUND: Somatostatin has been shown to offer a distinct advantage over antisecretory drugs in the management of peptic ulcer bleeding (PUB). However, rebleeding rates are still high in spite of endoscopic and medical treatment. In this study, we intended to determine whether combined therapy of a proton pump inhibitor (PPI) plus somatostatin is more beneficial than a PPI alone in patients with PUB. METHODS: We enrolled 90 consecutive patients who presented with PUB between January 2006 and October 2007. All the patients were managed with endoscopic hemostasis and divided into two treatment groups: 1) PPI alone (group A) and 2) PPI plus somatostatin (group B). The primary outcome was rebleeding within 72 hours. The secondary outcomes were rebleeding in 30 days, packed red blood cells (pRBC) transfused, length of hospital stay, need for surgery, and in-hospital mortality. RESULTS: Forty-five patients in the PPI group (A) and 45 patients in the PPI plus somatostatin group (B) were studied. There was no difference between the two groups with respect to clinical and endoscopic features at admission. After medical treatment, there was no difference between groups A and B in rebleeding at 72 hours (11% vs. 13%, p = NS), rebleeding in 30 days (13% vs. 16%, p = NS), pRBC transfused (mean, 3.2 vs. 4.5 units, p = NS), length of hospital stay (mean, 7.4 vs. 8.4 days, p = NS), and in-hospital mortality (2% vs. 7%, p = NS). CONCLUSIONS: Combined therapy with PPI and somatostatin did not result in better outcomes than PPI alone.

Objective:
The chest compression depth recommended in the current guidelines for average adult cardiopulmonary resuscitation is approximately 1/4-1/5 depth of the external chest anteroposterior (AP) diameter and at least 50 mm but less than 60 mm. The purpose of this study was to determine the proper compression depth in patients with amyotrophic lateral sclerosis (ALS).
Methods:
A retrospective analysis of the chest computed tomography scans obtained between January 2014 and December 2018 was performed, and the chest anatomical parameters, such as external, internal chest, and heart AP diameters, were measured. The primary outcomes were a 1/4 and 1/5 depth of an external chest AP diameter. Based on the values of these parameters, the heart compression fractures (HCF) and over compression depth (OCD) from 40 to 60 mm depths with every 5 mm interval were calculated. All outcomes in the two groups were compared.
Results:
Ninety three of 108 ALS and 93 of 17,150 healthy individuals were selected randomly from a database and analyzed. The mean±standard deviations of 1/4 and 1/5 depth of the external chest AP diameter in ALS were significantly lower than in healthy individuals (48.57±4.60 mm vs. 53.43±4.93 mm, 38.86±3.68 mm vs. 42.75±3.94 mm, respectively, all P<0.001). The HCF values were similar in the two groups. The number of OCD with 55 and 60 mm in the ALS group were increased (all P<0.05, univariate analysis)
Conclusion
An approximately 50 mm depth of chest compression could be appropriate, but an excessive depth greater than 55 mm is more likely to cause complications for ALS patients.

PURPOSE: The aim of this study was to describe clinical, biochemical, and radiologic features in patients with pyogenic liver abscess and to investigate predictors of septic shock. METHODS: We consecutively included subjects who were diagnosed as pyogenic liver abscess in the emergency department (ED) from January 1st, 2010 to June 30th, 2013. Through review of medical records, clinical, biochemical, and radiologic data were collected. The primary endpoint was septic shock during hospitalization. RESULTS: A total of 228 patients were included, with a mean age of 60.8+/-12.8 years, and 63.2% were men. Among them, 198 patients presented with fever and GCS <15 was observed in 15. Klebsiella spp. was most commonly identified in 33.8%, followed by E. coli and Streptococci spp. in 7% for each. Septic shock occurred in 55 (22.4%) and mortality rate was 1.3%. In univariable logistic regression, GCS <15, systolic BP <90 mmHg, pulse rate > or =120/min, respiratory rate > or = 22/min, body temperature (BT) > or =38degrees C, WBC, platelet, BUN, creatinine, albumin, AST, alkaline phosphatase (ALP), Creactive protein (CRP), abscess size > or =5 cm, and bilobal involvement were significantly associated with septic shock (p<0.05). In multivariate analysis, systolic BP <90 mmHg (OR 95.79, 95% CI: 11.16-822.02), BT > or =38degrees C (OR 1.95, 1.36-2.78), BUN (OR 1.03, 1.01-1.06), ALP (OR 1.003, 1.000-1.005), and abscess size > or =5 cm (OR 2.31, 1.08-4.94) were independent predictors of septic shock. CONCLUSION: Low Systolic Bp, High Bt, Elevated Bun And Alp, And Abscess Size > or =5 Cm Were Independently Associated With Septic Shock In Patients With Pyogenic Liver Abscess.

Journal of the Korean Society of Emergency Medicine 2010;21(1):44-47
PURPOSE: The aim of this study was to investigate the optimal length of a central venous catheter (CVC) inserted through the right internal jugular vein METHODS: During a 4-month period, we prospectively studied 374 patients who required a CVC. We enrolled 39 patients who underwent chest computed tomography (CT). The skin was punctured at the anterior border of the sternocleidomastoid muscle and at mid-distance between the angle of the mandible and the sternoclavicular junction. We measured the distance from catheter insertion to the superior vena cava/right atrium (SVC/RA) junction and calculated the recommended depth. RESULTS: The optimal length of a CVC inserted via the right internal jugular vein was 15 cm, this was based on the mean distance from the CVC insertion point to the distal SVC. By using these guidelines, the initial placement of a CVC in the distal SVC was more accurate than using other formulas (92.3% vs. 76.9%). CONCLUSION: To increase the likelihood of optimal tip location within the SVC on the first attempt and elimination of reposition, we suggest using the recommended depth instead of a formula to guide catheter placement.

Journal of Korean Medical Science 2023;38(50):e418-
Background:
There is a need to update the cardiovascular (CV) Sequential Organ Failure Assessment (SOFA) score to reflect the current practice in sepsis. We previously proposed the modified CV SOFA score from data on blood pressure, norepinephrine equivalent dose, and lactate as gathered from emergency departments. In this study, we externally validated the modified CV SOFA score in multicenter intensive care unit (ICU) patients.
Methods:
A multicenter retrospective observational study was conducted on ICU patients at six hospitals in Korea. We included adult patients with sepsis who were admitted to ICUs. We compared the prognostic performance of the modified CV/total SOFA score and the original CV/total SOFA score in predicting 28-day mortality. Discrimination and calibration were evaluated using the area under the receiver operating characteristic curve (AUROC) and the calibration curve, respectively.
Results:
We analyzed 1,015 ICU patients with sepsis. In overall patients, the 28-day mortality rate was 31.2%. The predictive validity of the modified CV SOFA (AUROC, 0.712; 95% confidence interval [CI], 0.677–0.746; P < 0.001) was significantly higher than that of the original CV SOFA (AUROC, 0.644; 95% CI, 0.611–0.677). The predictive validity of modified total SOFA score for 28-day mortality was significantly higher than that of the original total SOFA (AUROC, 0.747 vs. 0.730; 95% CI, 0.715–0.779; P = 0.002). The calibration curve of the original CV SOFA for 28-day mortality showed poor calibration. In contrast, the calibration curve of the modified CV SOFA for 28-day mortality showed good calibration.
Conclusion
In patients with sepsis in the ICU, the modified SOFA score performed better than the original SOFA score in predicting 28-day mortality.

BACKGROUND/AIMS: The aim of this study was to identify the ability of Glasgow-Blatchford score (GBS) and pre-endoscopic Rockall score (pre-E RS) to predict the occurrence of hypotension in patients with non-variceal upper gastrointestinal bleeding who are initially normotensive at emergency department. METHODS: Retrospective observational study was conducted at Asan Medical Center emergency department (ED) in patients who presented with non-variceal upper gastrointestinal bleeding from January 1, 2011 to December 31, 2013. Study population was divided according to the development of hypotension, and demographics, comorbidities, and laboratory findings were compared. GBS and pre-E RS were estimated to predict the occurrence of hypotension. RESULTS: A total of 747 patients with non-variceal upper gastrointestinal bleeding were included during the study period, and 120 (16.1%) patients developed hypotesion within 24 hours after ED admission. The median values GBS and pre-E RS were statistically different according to the occurrence of hypotension (8.0 vs. 10.0, 2.0 vs. 3.0, respectively; p<0.001). In the receiver operating characteristic curve analysis of hypotension development, the area under the curve of GBS and pre-E RS were 66% and 64%, respectively. The sensitivity and the specificity of GBS using optimal cut-off value were 81% and 46%, respectively, while those based on the pre-E RS were 74% and 46%, respectively. CONCLUSIONS: GBS and pre-E RS were both not sufficient for predicting the occurrence of hypotension in non-variceal upper gastrointestinal bleeding. Development of other scoring systems are needed.

PURPOSE: The Surviving Sepsis Campaign recommend initiating broad spectrum antibiotics within the first hour of recognition of septic shock. An unknown proportion of the effectiveness of earlier antibiotics administration will remain in septic shock patients treated with an early quantitative resuscitation in emergency department (ED). We were to compare the 28-day mortality between earlier antibiotic administration (< or =1 hour) and early antibiotic administration (1 hour to 6 hour) in septic shock patients in ED. METHODS: A total of 536 consecutive septic shock patients were prospectively collected from January 2010 to June 2012. We identified 357 patients who were developed shock at initial assessment, and measured the time of initial antibiotics administration. The primary outcome was 28-day mortality. RESULTS: Mean age was 62.8+/-13.7 years old and 222 patients were male (62.2%). The median time from shock recognition-to-antibiotics administration was 94.0 min (IQR 47.0-150.0) and 28-day mortality rate was 20.2%. When the relationship of 28-day mortality between earlier antibiotic administration (< or =1 hour) and early antibiotic administration (1 hour to 6 hour) was compared, no significant difference was shown (19.5% vs. 20.5%, p=0.82). CONCLUSION: Earlier antibiotics administration may have no additional outcome value in septic shock patients treated with an early quantitative resuscitation in ED.
