Prognostic utility of paraspinal muscle index in elderly patients with community-acquired pneumonia.

Objective: This study investigated the associations between paraspinal muscle measurements on chest computed tomography and clinical outcomes of elderly patients with community-acquired pneumonia (CAP).

Methods: This single-center, retrospective, observational study analyzed elderly patients (≥65 years) with CAP hospitalized through an emergency department between March 2020 and December 2022. We collected their baseline characteristics and laboratory data at the time of admission.

Survival benefit of direct transport to trauma centers among patients with unintentional injuries in Korea: a propensity score-matched analysis.

Objective: This study investigated the characteristics and survival rates of patients with unintentional severe trauma who visited a regional trauma center (TC) or a non-TC.

Methods: This retrospective, national, population-based, observational, case-control study included patients with abnormal Revised Trauma Score from January 2018 to December 2018. We divided hospitals into two types, TC and non-TC, and compared several variables, including in-hospital mortality.

Gender effect in survival after out-of-hospital cardiac arrest: A nationwide, population-based, case-control propensity score matched study based Korean national cardiac arrest registry.

Objective: This study aimed to describe the relationship between sex and survival of patients with out-of-hospital cardiac arrest (OHCA) and further investigate the potential impact of female reproductive hormones on survival outcomes, by stratifying the patients into two age groups.

Methods: This retrospective, national population-based observational, case-control study, included Korean OHCA data from January 1, 2009, to December 31, 2016. We used multiple logistic regression with propensity score-matched data.

Parosmia in Right-lateralized Semantic Variant Primary Progressive Aphasia: A Case Report.

Parosmia, defined as the distorted perception of an odor stimulus, has been reported to be associated with head trauma, upper respiratory tract infections, sinonasal diseases, and toxin/drug consumption. To date, little is known about parosmia in right-lateralized semantic variant primary progressive aphasia. A 60-year-old right-handed man presented with a 2-year history of parosmia and prosopagnosia.

The relationship between body mass index and N-terminal pro-B-type natriuretic peptide in community-acquired pneumonia.

Background: The relationship between body mass index (BMI) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) has not been fully investigated in patients with community-acquired pneumonia (CAP).

Methods: This prospective observational study examined 510 consecutive patients hospitalized for CAP. NT-proBNP, BMI, and the pneumonia severity index (PSI) were determined for all participants.

Acute Phlegmonous Gastritis Complicated by Subphrenic Abscess.

Background: Phlegmonous gastritis (PG) is a rare and potentially fatal disease characterized by bacterial infection of the gastric wall. However, its clinical features are nonspecific, which may delay its diagnosis and treatment.

Case Report: We report a case of a previously healthy 53-year-old woman with localized PG complicated by subphrenic abscess formation who was treated successfully with antibiotics and percutaneous catheter drainage.

Serum cholesterol as a predictor of mortality among the elderly patients with pneumonia in the emergency department.

Background: Reduced cholesterol levels are associated with poor outcomes in critically ill patients. However, the effect of reduced cholesterol levels on the prognosis of patients with community-acquired pneumonia (CAP) is unclear. This study aimed to investigate the association between serum total cholesterol levels and the clinical outcomes of elderly patients with CAP.

A 70-Gene Signature for Predicting Treatment Outcome in Advanced-Stage Cervical Cancer.

Cervical cancer is the fourth most common cancer in women worldwide. The current approaches still have limitations in predicting the therapy outcome of each individual because of cancer heterogeneity. The goal of this study was to establish a gene expression signature that could help when choosing the right therapeutic method for the treatment of advanced-stage cervical cancer.

Evaluation of usefulness of smart device-based testing: a survey study of Korean medical students.

Purpose: This study aims to understand the characteristics of smart device-based testing (SBT) by comparing the typical characteristics of students' satisfaction with SBT, its usefulness, advantages, and disadvantages when compared with existing testing methods.

Methods: A total of 250 students from the first to third year were selected as the final targets of the study and the questionnaire was developed by faculty members who participated in the survey from the start of the SBT. The total number of questions is 12, and the questionnaire used a 4-point scale.

Femoral Intertrochanteric Fractures of the Patients in the Emergency Department due to Minor Falls: Special Consideration in the Middle-old to Oldest-old Patients.

Background: The older population (≥65 years) has rapidly increased in size in recent years. Among them, the middle-to-oldest-old (≥75 years) tend to have a poor health status. Therefore, subdivision and evaluation of older patients with traumatic injury are required.

Usefulness of the Geriatric Nutritional Risk Index to predict the severity of cholecystitis among older patients in the emergency department.

Aim: We sought to investigate whether the Geriatric Nutritional Risk Index is associated with systemic organ dysfunction among older patients who present with cholecystitis to the emergency department.

Methods: This was an observational retrospective study among consecutive older patients with cholecystitis in the emergency department from 2012 to 2018. We collected baseline characteristics and laboratory data, and re-categorized the Geriatric Nutritional Risk Index into three risk groups.

PAC-5 Gene Expression Signature for Predicting Prognosis of Patients with Pancreatic Adenocarcinoma.

Pancreatic adenocarcinoma (PAC) is one of the most aggressive malignancies. Intratumoural molecular heterogeneity impedes improvement of the overall survival rate. Current pathological staging system is not sufficient to accurately predict prognostic outcomes.
