Background:
Although Asia shoulders a considerable burden of tracheal, bronchial, and lung (TBL) cancers, the associated macroeconomic impact has yet to be adequately investigated.
Methods:
Using 2023 data from the Global Burden of Disease Study and the World Bank, we applied the value of a statistical life year (VSLY) method to estimate the economic welfare losses attributable to TBL cancers in Asian countries. We further analyzed the temporal trends, sex and age-specific disparities, and the drivers of economic inequality and projected the burden trends to 2050.
Results:
In Asia, the value of lost welfare (VLW) due to these cancers reached USD 3.28 (95% UI, 2.6301-4.0572) trillion, equivalent to 4.18% (95% UI, 3.35-5.17) of the regional GDP. Temporal trend analyses revealed a consistent upward trajectory in both absolute VLW and its GDP share. Sex-stratified analyses showed that the burden was significantly higher in male populations, and age-specific peaks occurred at 70-74 years for both sexes. Health inequality metrics indicated a pronounced widening of relative disparities over time. Projection models forecast a continued increase in absolute VLW, whereas its proportional contribution to GDP is expected to plateau.
Conclusion:
These findings establish that TBL cancers impose a substantial and inequitably distributed macroeconomic burden across Asia. The pronounced sex and region-specific disparities underscore the urgent need for evidence-based, geographically targeted intervention strategies. Prioritizing the targeted deployment of resources in high-burden zones is critical to mitigating economic losses and improving survival outcomes in the region.

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
