Artificial intelligence is steadily permeating various sectors, including healthcare. This research specifically addresses lung cancer, the world's deadliest disease with the highest mortality rate. Two primary factors contribute to its onset: genetic predisposition and environmental factors, such as smoking and exposure to pollutants.

The present study was carried out to demonstrate this variation in the prevalence of mAA dilation and to identify the optimal definition by creating the largest DONS.
Methods: Echocardiographic studies of patients ≥ 15 years of age performed at a large tertiary care center over 4 years ( = 49,330) were retrospectively evaluated.
Background: We aimed to test the hypothesis that there is an association between hypertrophic cardiomyopathy and dilated aorta in a case-control, matched-design fashion.
Methods: Of 65,843 studies done from November 2011 to December 2015, we found, after detailed evaluation by a single author, 153 cases of hypertrophic cardiomyopathy and 3,213 controls who were classified as normal clinically and echocardiographically. Controls were defined as normal patients referred to the echocardiography laboratory with no diagnoses and no known risk factors for dilated aorta (e.
Objectives: The cutoff for dilated mid-ascending aorta (mAA) is controversial and has several definitions. The present study was carried out to determine the prevalence of mAA dilation based on published definitions and to identify the optimal cutoff.
Methods: Echocardiographic studies of patients >15 years of age performed at a large tertiary care center over 4 years, = 49,330, were retrospectively evaluated.
Article Synopsis
- Multiple studies suggest that pulse pressure (PP) is a strong indicator of aortic calcification, but this study is the first to examine PP's correlation with aortic calcification at specific segments.
- The research involved 37 patients whose aortic PP was measured and compared across different aortic segments (ascending, arch, descending) for calcification.
- Results showed that calcification was most prevalent in the descending aorta, with a significant correlation between higher PP and lower compliance, especially in this segment, indicating its key role in influencing PP compared to other aortic sections.
