Article Abstract
Background: This study aimed to validate the Geriatric Trauma Outcome Score (GTOS) for predicting mortality associated with trauma in older Korean adults and compare the GTOS with the Trauma and Injury Severity Score (TRISS).
Methods: This study included patients aged ≥65 years who visited the Chungbuk National University Hospital Regional Trauma Center between January 2016 and December 2022. We used receiver operating characteristic curves and calibration plots to assess the discrimination and calibration of the scoring systems.
Results: Among 3,053 patients, the median age was 77 years, and the mortality rate was 5.2%. The overall GTOS-predicted mortality and 1-TRISS were 5.4% (interquartile range [IQR], 3.7-9.5) and 4.7% (IQR, 4.7-4.7), respectively. The areas under the curves (AUCs) of 1-TRISS and GTOS for the total population were 0.763 (95% confidence interval [CI], 0.719-0.806) and 0.794 (95% CI, 0.755-0.833), respectively. In the Glasgow Coma Scale (GCS) ≤12 group, the in-hospital mortality rate was 27.5% (79 deaths). The GTOS-predicted mortality and 1-TRISS in this group were 18.6% (IQR, 7.5-34.7) and 26.9% (IQR, 11.9-73.1), respectively. The AUCs of 1-TRISS and GTOS for the total population were 0.800 (95% CI, 0.776-0.854) and 0.744 (95% CI, 0.685-0.804), respectively.
Conclusion: The GTOS and TRISS demonstrated comparable accuracy in predicting mortality, while the GTOS offered the advantage of simpler calculations. However, the GTOS tended to underestimate mortality in patients with GCS ≤12; thus, its application requires care in such cases.

Pulmonary Function Test Reference Equations May Affect Classification of Restrictive Lung Disease Severity in Systemic Sclerosis.

Background: Interstitial lung disease (ILD) is a significant cause of morbidity and mortality in systemic sclerosis (SSc), particularly among Black patients. Pulmonary function tests (PFTs) are critical to screen for and monitor SSc-ILD. We examined whether race-specific and race-neutral PFT reference equations impact classification of restrictive lung disease (RLD) severity in Black and White patients with SSc.

Preclinical stroke research faces a critical translational gap, with animal studies failing to reliably predict clinical efficacy. To address this, the field is moving toward rigorous, multicenter preclinical randomized controlled trials (mpRCTs) that mimic phase 3 clinical trials in several key components. This collective statement, derived from experts involved in mpRCTs, outlines considerations for designing and executing such trials.

Objectives: This study aimed to evaluate the predictive accuracy of Paediatric Risk of Mortality-III, Paediatric Index of Mortality-II, and Paediatric Logistic Organ Dysfunction scoring systems for major adverse events following congenital heart surgery.
Methods: This prospective observational study included patients under 18 years of age who were admitted to the ICU for at least 24 hours postoperatively following congenital heart surgery. Major adverse events were defined as a composite of 30-day mortality, ICU readmission, reintubation, acute neurologic events, requirement for extracorporeal membrane oxygenation, cardiac arrest requiring cardiopulmonary resuscitation, need for a permanent pacemaker, acute kidney injury, or unplanned reoperation.
Predictive role of loneliness on mortality before the age 85 years among mid- to later-life adults in the United States: a 10-year retrospective cohort study.

Aims: Loneliness is a common public health concern, particularly among mid- to later-life adults. However, its impact on early mortality (deaths occurring before reaching the oldest old age of 85 years) remains underexplored. This study examined the predictive role of loneliness on early mortality across different age groups using data from the Health and Retirement Study (HRS).

Radical esophagectomy remains the cornerstone of curative treatment for esophageal cancer, but is frequently complicated by postoperative events, most notably anastomotic leakage. Anastomotic leakage, occurring in up to 30% of cases, is multifactorial in origin and significantly increases morbidity and mortality. This review aims to summarize current management strategies, highlight emerging therapies, and identify persistent clinical challenges related to this complication.
