Background/aim: To evaluate the predictive factors in older patients with localized esophageal cancer treated with definitive radiotherapy.
Patients And Methods: We retrospectively analyzed patients aged ≥75 years who were treated with three-dimensional conformal radiotherapy between 2008 and 2017. The patients were classified into the oldest-old group (≥80 years) and the old group (75-79 years).
Results: Fifty patients were identified, 28 in the oldest-old group and 22 in the old group. Forty-six patients (92%) completed the planned radiotherapy. The median follow-up time was 21 months. Two-year overall survival (OS), disease-free survival, and locoregional control rates were 53%, 42%, and 51%, respectively. Univariate analyses for OS showed that neither the radiotherapy field nor total radiotherapy dose was a significant factor. Clinical T stage, clinical N stage, and age were independent predictors of OS.
Conclusion: Age ≥80 years is an independent prognostic factor for OS. Elective nodal irradiation and total radiotherapy dose above 50.4 Gy did not improve survival. Our findings may help in the treatment decisions for localized esophageal cancer in older patients.

Objectives: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide, particularly among the elderly, resulting in high rates of intensive care unit (ICU) admissions. Malnutrition is common in elderly patients and has been associated with poor prognosis in patients with COPD. However, its impact in the ICU setting remains incompletely defined.

Background: Invasive fungal infections have been reported as complications with significant mortality and morbidity in patients hospitalized with COVID-19. This study aimed to evaluate the clinical characteristics and outcomes of candidaemia patients with COVID-19 and to investigate the association between COVID-19 and mortality in candidaemia patients.
Methods: This retrospective study included candidaemia patients aged 18 years or older admitted to four university-affiliated tertiary hospitals in South Korea between January 1, 2020, and December 31, 2022.

Background And Aims: This study evaluated the predictive value of the APF risk score in East Asian patients undergoing open nephrectomy and its correlation with hypertension and NAFLD.
Methods And Results: A retrospective study used the clinical data of 82 patients who underwent ON between January 2010 and December 2022. Per their APF score, patients were categorized into groups A (0-2 points) and B (3-4 points).
Linking structural and functional changes during healthy aging and semantic dementia using multilayer brain network analysis.

Healthy aging is characterized by frontal and diffuse brain changes, while certain age-related pathologies such as semantic dementia will be associated with more focal brain lesions, particularly in the temporo-parietal regions. These changes in structural integrity could influence functional brain networks. Here we use multilayer brain network analysis on structural (DWI) and functional (fMRI) data in younger and older healthy individuals and patients with semantic dementia.

Introduction: The choroid plexus (CP) may play a crucial role in brain degeneration. We aim to assess whether CP cysts (CPCs), defined using ultra-high field magnetic resonance imaging (MRI), relate to aging and neurodegeneration.
Methods: We used multi-sequence 7T MRI to observe CPCs, characterizing their presence and characteristics in healthy younger controls, healthy older controls (OCs), patients with Alzheimer's disease (AD), patients with Parkinson's disease (PD), and patients with uremic encephalopathy.
