No medication prescription and residential distance from the hospital are important factors associated with nonsurgical weight-loss treatment discontinuance in Japanese patients with high-degree obesity: a retrospective study.

Background: Although the percentage of the population with a high degree of obesity (body mass index [BMI] ≥ 35 kg/m) is low in Japan, the prevalence of obesity-related diseases in patients with high-degree obesity is greater than that in patients with a BMI < 35 kg/m. Therefore, treatment for high-degree obesity is important. However, clinical studies have reported that 20-50% of patients with obesity discontinue weight-loss treatment in other countries.

Prognostic Factors in Japanese EGFR Mutation-Positive Non-Small-Cell Lung Cancer: A Real-World Single-Center Retrospective Cohort Study.

Background: The prognosis of patients with epidermal growth factor receptor (EGFR) mutation-positive lung cancer has improved significantly since the advent of EGFR tyrosine kinase inhibitors (EGFR-TKIs). We aimed to investigate the relationship between patient characteristics, EGFR genotype, therapeutic agents, and the prognosis of the patients with EGFR mutation-positive lung cancer.

Methods: This retrospective cohort study analyzed 198 Japanese patients with unresectable EGFR mutation-positive lung cancer who were treated with EGFR-TKIs at Toho University Sakura Medical Center from April 2006 to December 2021.

Significance of Systemic Scleroderma-Specific Autoantibodies in Idiopathic Interstitial Pneumonia.

Objective Patients with idiopathic interstitial pneumonia (IIP) often test positive for systemic scleroderma-specific autoantibodies (SSc-Ab), even if they do not meet the diagnostic criteria for systemic scleroderma (SSc). However, the significance of SSc-Ab in IIP is unknown. Methods We retrospectively studied the medical records of all patients suspected of interstitial lung disease (ILD) who visited our center between January 2016 and December 2021.
