Incorporating Lymph Node Size at CT as an N1 Descriptor in Clinical N Staging for Lung Cancer.

Background The ninth edition of the TNM classification for lung cancer revised the N2 categorization, improving patient stratification, but prognostic heterogeneity remains for the N1 category. Purpose To define the optimal size cutoff for a bulky lymph node (LN) on CT scans and to evaluate the prognostic value of bulky LN in the clinical N staging of lung cancer. Materials and Methods This retrospective study analyzed patients who underwent lobectomy or pneumonectomy for lung cancer between January 2013 and December 2021, divided into development (2016-2021) and validation (2013-2015) cohorts.

Recent advances in the regulatory and non-coding RNA biology of osteogenic differentiation: biological functions and significance for bone healing.

Injuries associated with contemporary life, such as automobile crashes and sports injuries, can lead to large numbers of traumatic neuromuscular injuries that are intimately associated with bone fractures. Regulatory and non-coding RNAs play essential roles in multiple cellular processes, including osteogenic differentiation and bone healing. In this review, we discuss the most recent advances in our understanding of the regulatory and non-coding RNA biology of osteogenic differentiation in stem, stromal and progenitor cells.

Evolving trends in the prevalence and treatment of ankylosing spondylitis in Korea from 2010 to 2023: a population-based study.

Ankylosing spondylitis (AS) is a chronic inflammatory disease affecting the axial skeleton, resulting in severe pain, decreased mobility, and irreversible structural damage. This study explores the evolving prevalence, patient demographics, and treatment trends for AS in the Korean population from 2010 to 2023, alongside advancements in targeted therapies. This population-based study utilized data from the National Health Insurance Database covering 2010 to 2023.

Long-term high fat diet aggravates the risk of lung fibrosis and lung cancer: transcriptomic analysis in the lung tissues of obese mice.

Background: Previous studies reported significant relationships between obesity and pulmonary dysfunction. Here, we investigated genetic alterations in the lung tissues of high fat diet (HFD) induced obese mouse through transcriptomic and molecular analyses.

Methods: Eight-week-old male C57BL/6J mice were fed either a normal chow diet (NCD) or HFD for 12 weeks.

Evaluating the association of genotype and cognitive resilience in SuperAgers.

Importance: "SuperAgers" are oldest-old adults (ages 80+) whose memory performance resembles that of adults in their 50s to mid-60s. Factors underlying their exemplary memory are underexplored in large, racially diverse cohorts.

Objective: To determine the frequency of genotypes in non-Hispanic Black and non-Hispanic White SuperAgers compared to middle-aged (ages 50-64), old (ages 65-79), and oldest-old (ages 80+) controls and Alzheimer's disease (AD) dementia cases.
