We found that 48 hours of therapeutic hypothermia was more effective in attenuating brain apoptosis than 24 hours of therapeutic hypothermia. We also found that the antiapoptotic effects of therapeutic hypothermia were associated with the suppressions of the cleavage of protein kinase C-δ, the cytosolic release of cytochrome c, and the cleavage of caspase 3.

BACKGROUND AND AIMS: Emerging evidence supports artificial intelligence-enhanced electrocardiogram (AI-ECG) for detecting acute myocardial infarction (AMI), but real-world validation is needed. The aim of this study was to evaluate the performance of AI-ECG in detecting AMI in the emergency department (ED). METHODS: The Rule-Out acute Myocardial Infarction using Artificial intelligence Electrocardiogram analysis (ROMIAE) study is a prospective cohort study conducted in the Republic of Korea from

Single dose of selenium post-treatment activates GPx and attenuates lipid peroxidation and lung injury early after paraquat intoxication, but does not improve 72 hours of survival.

A high dose of niacin attenuated lung inflammation, suppressed proinflammatory cytokine release, reduced histologic lung damage, and improved survival after HS in rats. Its therapeutic benefits were associated with the down-regulation of the reactive oxygen species-dependent NF-κB pathway.

Single high dose and repeated low dose of niacin attenuated brain injury and improved neurological outcome after cardiac arrest in rats. Their therapeutic benefits were associated with suppressions of the phosphorylations of p38 and c-Jun N-terminal kinase/stress-activated protein kinase and the cleavage of caspase 3.

Background: Social changes related to the elderly in regard to factors such as population, region, cohabitant status and depression incidence, have recently been observed. The aim of our study was to investigate the characteristics of elderly suicide attempters according to these changes. Methods: We retrospectively reviewed the medical records of suicide attempters who visited an Emergency Department between January 2013 and March 2016. Patients were classified into an elderly or non-elderly gr

A higher incidence of femoral intertrochanteric fractures from minor falls was found among middle-old to oldest-old patients compared to that in young-old patients. Therefore, physicians should perform more thorough physical examinations and radiograph reading in middle-old to oldest-old patients even if the patients do not complain of pain.

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. We ca

Toxic shock syndrome (TSS) is a rare but life-threatening illness that is mainly caused by toxigenic strains of Staphylococcus aureus. Although TSS is classically known to be associated with tampon use, the number of TSS cases with non-menstrual causes such as skin and soft tissue infection has been increasing. Tattooing can result in several complications such as localized and systemic infections, inflammatory skin eruptions and neoplasms. We recently experienced a 26-year-old man diagnosed wit

Sex differences in the in-hospital management of sepsis exist. Previous studies either included patients with sepsis that was defined using previous definitions of sepsis or evaluated the 3-h bundle therapy. Therefore, this study sought to assess sex differences in 1-h bundle therapy and in-hospital management among patients with sepsis and septic shock, defined according to the Sepsis-3 definitions. This observational study used data from Korean Shock Society (KoSS) registry, a prospective mult

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. The paraspina
