Abstract

fetched live from OpenAlex

This chapter introduces drug abuse as a widespread public health problem with several medical complications that are infectious due to the transmission of blood-borne, environmental, and respiratory infectious agents. An ongoing opioid epidemic has changed the face of addiction in the United States and Canada and resulted in many publications about medical complications associated with substance abuse. Non-injection and injecting drug users (DUs/IDUs) are less likely to access care and maintain adherence for optimal benefit due to social and access factors related to criminalization and economic status. Endocarditis has emerged as the most serious infectious complication in the injection user. The chapter highlights complications due to intravenous drug use that include pneumonia, aspiration pneumonitis, lung abscess, and septic pulmonary emboli.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
