Finding better ways to screen for tuberculosis in Brazilian prisons

Identifying effective and efficient approaches to tuberculosis screening in Brazilianprisons

['FUNDING_CAREER'] · BOSTON UNIVERSITY MEDICAL CAMPUS · NIH-11001464

This study is looking to find better ways to detect tuberculosis in prisoners in Brazil who can't provide the usual samples for testing, using a new method that captures bacteria from their breath, to help ensure that everyone gets the care they need.

What this research studies

This research aims to improve tuberculosis detection among prisoners in Brazil, a high-risk group with a significant disease burden. The project will assess the prevalence of undiagnosed tuberculosis in inmates who cannot provide sputum samples, which are typically required for diagnosis. It will also evaluate a new diagnostic tool called the Mask Aerosol Sampling system (MASS) that captures exhaled bacteria, and develop cost-effective screening algorithms to enhance case detection. By focusing on non-sputum-based methods, the research seeks to address the limitations of current diagnostic practices in this vulnerable population.

Who could benefit from this research

Good fit: Ideal candidates for this research are incarcerated individuals in Brazilian prisons who are at high risk for tuberculosis and unable to provide sputum samples.

Not a fit: Patients outside of the prison system or those who can provide sputum samples may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to earlier detection and treatment of tuberculosis in Brazilian prisons, ultimately reducing transmission and improving health outcomes for inmates.

How similar studies have performed: Previous studies have shown success in tuberculosis screening in high-risk populations, but the specific approach using the MASS tool is novel.
