Review of the Canadian Nontuberculous Mycobacterial Disease Landscape—Challenges and Opportunities
Bibliographic record
Abstract
The incidence and prevalence of nontuberculous mycobacterial (NTM) disease are rising. This narrative review examines the evolution of NTM disease trends over the past four decades, in Canada and globally, encompassing changing epidemiology, shifting treatment paradigms, and emerging antimicrobial resistance patterns. Challenges to NTM treatment are explored, and novel and investigational therapies are summarized. Key themes include a significant increase in NTM disease incidence, temporal shifts in the dominant species causing human infections, evolution from single-drug to multi-drug treatment approaches, and growing concerns regarding macrolide resistance. The substantial challenges with treatment tolerability, effectiveness, and access are outlined. This review synthesizes data from multiple sources, including peer-reviewed literature, clinical trials, and public health databases, to provide a comprehensive understanding of the changing NTM disease landscape in Canada and more broadly. There is a need for expanded surveillance, continued innovation, and a multidisciplinary approach to NTM management.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
