Abstract

fetched live from OpenAlex

Introduction Radiotherapy is a challenge in autologous breast reconstruction because of its impact on cutaneous and vascular systems. Hyperbaric oxygen therapy (HBOT) is a recognized treatment of radiation-related complications. We aim at assessing the impact of peri-operative HBOT on irradiated breast microvascular reconstructive outcomes. Method We reviewed medical charts of patients who received radiotherapy and then underwent secondary free autologous breast reconstruction at our institution. Demographic, HBOT protocol, intervention characteristics and recipient-site complications were collected. Outcomes of irradiated patients were then compared between HBOT and non-HBOT groups. Results Fourteen patients were included (eleven unilateral and two bilateral deep inferior epigastric artery perforator flap (DIEP) and one free transverse rectus abdominis muscle flap (f-TRAM)). Seven patients received HBOT and seven did not. In the non-HBOT group, there were one Clavien-Dindo grade II, one Clavien-Dindo grade IIIa and two Clavien-Dindo grade IIIb post-operative complications. In the HBOT group, there were three Clavien-Dindo grade I, one Clavien-Dindo grade IIIa and two Clavien-Dindo grade IIIb post-operative complications. Mean operative time was 452.3 minutes (SD ± 62.4) for unilateral cases without HBOT and 457.8 minutes (SD 102.1) with HBOT ( p =0.913). Mean ischemia time per flap without HBOT was 109.4 minutes (SD 51.8), versus 80.1 minutes (SD 37.7) in the HBOT group ( p =0.249). Conclusion This study gives insights on the potential of HBOT treatment in preparing irradiated breast cancer patients for secondary autologous reconstruction. IRB CCER 2024-00007

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.
