Abstract

fetched live from OpenAlex

Point Of Care Ultrasound (POCUS) guided peripheral intravenous (PIV) access offers a safer and more efficient alternative for patients with difficult venous access. A systematic review of 15 studies with 1485 patients, sourced from five databases, including PubMed, Cochrane Library, MEDLINE, Web of Science, and Google Scholar, showed POCUS significantly improved success rates (OR: 4.25), first-attempt success (OR: 5.31), reduced attempts (MD: -0.83), and decreased procedure time (MD: -9.75 min). Fewer complications (OR: 0.49) observed with POCUS compared to standard techniques. Statistical analyses were conducted using Review Manager, and quality was assessed with Cochrane Risk of Bias and Newcastle Ottawa tools. Findings support POCUS as a safe, time-saving procedure for improving patient outcomes.

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.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
