Experimental studies on the structural dependence of stimulated Raman-like scattering in solid-core photonic crystal fibers.

The tight confinement of both optical and acoustic fields in their µm-sized fiber cores of photonic crystal fibers (PCFs) can lead to enhanced Brillouin light scattering in the forward direction, which is well-known as the stimulated Raman-like scattering (SRLS). In general, the gain spectra of SRLS in PCFs are dominated by the PCF core sizes. Meanwhile, their exact dependences upon the surrounding hollow channels have not been systematically studied in experiments.

International external validation of the SORG machine learning algorithm for predicting sustained postoperative opioid prescription after anterior cervical discectomy and fusion using a Taiwanese cohort of 1,037 patients.

Background Context: Anterior cervical discectomy and fusion (ACDF) is widely performed for cervical spine disorders, with opioids commonly prescribed postoperatively for pain management. However, prolonged opioid use carries significant risks such as dependency and adverse health effects. Predictive models like the SORG machine learning algorithm (SORG-MLA) have been developed to forecast prolonged opioid use post-ACDF.

Systematic review of 99 extremity bone malignancy survival prediction models.

Background: Various prediction models have been developed for extremity metastasis and sarcoma. This systematic review aims to evaluate extremity metastasis and sarcoma models using the utility prediction model (UPM) evaluation framework.

Methods: We followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and systematically searched PubMed, Embase, and Cochrane to identify articles presenting original prediction models with 1-year survival outcome for extremity metastasis and 5-year survival outcome for sarcoma.

Molecular mechanisms of vacuum therapy in penile rehabilitation: a novel animal study.

Background: Penile rehabilitation (PR) is widely applied after radical prostatectomy. Vacuum erectile device (VED) therapy is the one of three PR methods used in the clinical setting that improve erectile function (EF) and is the only PR method which may preserve penile length. However, its unknown mechanism hampered doctors' recommendations and patients' compliance.
