RESUMO
OBJECTIVE: The objective of the study was to describe a clinically useful factors index predicting long-term efficacy of uterine artery embolization (UAE). STUDY DESIGN: Newly diagnosed patients with uterine leiomyoma wishing to retain their uterus underwent UAE at our institution. Clinical demographics and 4 prognostic factors were recovered from the medical record. A regrowth-free interval (RFI) was calculated for all patients based on leiomyoma regrowth or recurrence of any previously reported symptoms. RFI by prognostic factor was analyzed by the Kaplan-Meier method. RESULTS: Forty-three patients were identified. Two prognostic factors were identified by multivariate analysis: vascularity (dichotomized as hypervascular vs hypovascular; RFI at 2 years, 80% vs 20%, P = .001) and number of nodules (solitary vs multiple; RFI at 2 years, 72% vs 25% at 2 years, P = .001) CONCLUSION: UAE success may be predicted by 2 preoperative parameters. Further investigation is warranted.

We report an ultrafast cross phase modulation (XPM) effect in intersubband transition (ISBT) of InGaAs/AlAs/AlAsSb coupled quantum wells, where the ISBT absorption of a transverse-magnetic mode pump signal induces phase modulation of a transverse-electric mode probe signal. Using waveguide-type ISBT devices, we have achieved XPM-based 10 Gbit/s wavelength conversion with a power penalty of 2.53 dB. Also, we propose XPM-based signal processing circuits for gate switching and modulation format conversion.
