Four-Year Follow-Up of Polyalkylimide Gel Use for the Treatment of HIV-Associated Lipoatrophy
Bibliographic record
Abstract
PURPOSE: To evaluate polyalkylamide gel (PAIG) use in treating HIV-associated facial lipoatrophy (FLA) 4 years after its injection in an open-label, randomized controlled trial (RCT). METHODS: Five patients were treated with PAIG in a pilot study, and 31 patients were subsequently enrolled in the RCT of immediate or delayed (12 weeks later) PAIG injections. Endpoints included proportion of participants with complications; changes in FLA severity score (FLSS); and quality of life (QoL), depression, anxiety, and satisfaction scores. Infections were classified as "confirmed" if purulent material was extracted and/or an organism cultured. Infections were classified as "possible" if only clinical signs were present without purulent discharge or microbiologic confirmation. RESULTS: Year 4 results were available for 5 pilot and 27 full-scale study participants. Delayed complications included 5 confirmed infections (15.6%), 3 possible infections (9.4%), nodules (25%), and bleeding (3%). No significant changes were observed between years 2 to 4 in patient-graded FLSS, QoL, depression, and anxiety scores. Whereas 94% of participants were satisfied with their overall treatment, only 69% were satisfied with PAIG treatment specifically. CONCLUSION: Even though PAIG treatment was associated with delayed complications including high rates of infection and nodules, most patients were satisfied with the treatment.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

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, unvalidatedLabeled directly by 2 models reading the full record.
