Efficacy of blood urea nitrogen and the neutrophil-to-lymphocyte ratio as predictors of mortality among elderly patients with genitourinary tract infections: A retrospective multicentre study.

Objectives: To investigate whether initial blood urea nitrogen (BUN) and the neutrophil-to-lymphocyte ratio (NLR) in the emergency department (ED) are associated with mortality in elderly patients with genitourinary tract infections.

Methods: A total of 541 patients with genitourinary tract infections in 5 EDs between November 2016 and February 2017 were included and retrospectively reviewed. We assessed age, sex, comorbidities, vital signs, and initial laboratory results, including BUN, NLR and the SOFA criteria.

The qSOFA score combined with the initial red cell distribution width as a useful predictor of 30 day mortality among older adults with infection in an emergency department.

Purpose: This study aimed to investigate whether the qSOFA and initial red cell distribution width (RDW) in the emergency department (ED) are associated with mortality in older adults with infections who visited the ED.

Methods: This was a retrospective study conducted in 5 EDs between November 2016 and February 2017. We recorded age, sex, comorbidities, body temperature, clinical findings, and initial laboratory results, including the RDW.

The neutrophil-to-lymphocyte ratio is associated with bacteremia in older adults visiting the emergency department with urinary tract infections.

Purpose: We evaluated the clinical features of older adults visiting the emergency department (ED) with urinary tract infections (UTIs), and the diagnostic utility of the neutrophil-to-lymphocyte ratio (NLR) in terms of identifying bacteremia.

Methods: In total, 479 older adults admitted with UTIs via the ED between January 2010 and December 2015 were retrospectively reviewed. We recorded age, sex, comorbidities, body temperature, clinical findings, and initial laboratory results, including the NLR.

Factors associated with delayed emergency room visits in adult immigrant patients with mild abdominal pain in Korea.

Objective: To determine the factors associated with unmet needs in immigrant patients complaining of abdominal pain, by analyzing those associated with the time from symptom onset to emergency room visit.

Methods: We retrospectively reviewed the medical records of immigrants with abdominal pain who visited a tertiary hospital emergency department from January to December 2016. The dependent variable was the time from symptom onset to emergency room visit.

Elderly patients visiting the emergency department for deliberate self-poisoning: do they present a more severe poisoning severity score than the nonelderly patients in the initial 24 h?

Purpose: Many elderly patients arrive at the emergency department (ED) complaining of deliberate self-poisoning (DSP). This study determined the poisoning severity of elderly patients who committed DSP.

Methods: A study was performed with 1329 patients (> 15 years of age) who were treated for DSP at two EDs between January 2010 and December 2016.

Management of right main bronchial rupture with a double lumen endotracheal tube in a patient with blunt chest trauma.

Tracheobronchial disruption is one of the most severe injuries caused by blunt chest trauma. It may cause airway obstruction and resulting life-threatening respiratory deficiency. However, the clinical presentations are variable and frequently difficult to diagnose.

Targeted temperature management after cardiac arrest with anaphylaxis.

Fatal anaphylaxis is uncommon but not rare. Extrapolated mortality rates are 0.52% of total anaphylaxis patients Bock et al.

Use of a slit-lamp microscope for treating impacted facial foreign bodies in the emergency department.

Identifying, locating, diagnosing, and treating small foreign bodies (FBs) in soft tissues is a challenge for emergency physicians in the emergency department. Additionally, potential complications owing to the remnant FBs are medico-legally significant. The efficacy of conventional imaging methods such as radiography, computed tomography, and ultrasonography are largely limited in visualizing FBs<2-mm.

Neutrophil-to-lymphocyte count ratio is associated with perforated appendicitis in elderly patients of emergency department.

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.

Are prognostic scores and biomarkers such as procalcitonin the appropriate prognostic precursors for elderly patients with sepsis in the emergency department?

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.
