Magnetic Field‐Assisted Conductive Nerve Guidance Conduit Enabling Peripheral Nerve Regeneration with Wireless Electrical Stimulation

Advanced Functional Materials, EarlyView.
This study introduces a conductive nerve guidance conduit integrated with wireless electrical stimulation through alternating magnetic fields, which induces currents and creates a supportive microenvironment for nerve regeneration. In vivo studies show that this approach significantly enhanced myelin restoration, gastrocnemius muscle regeneration ...

Predicting Postoperative Intraocular Lens Dislocation in Cataract Surgery via Deep Learning [PDF]

arXiv, 2023
A critical yet unpredictable complication following cataract surgery is intraocular lens dislocation. Postoperative stability is imperative, as even a tiny decentration of multifocal lenses or inadequate alignment of the torus in toric lenses due to postoperative rotation can lead to a significant drop in visual acuity.

Joule‐Assisted Nanotherapeutic Urethral Stent (JANUS) for Spatiotemporal Theragenerative Treatment of Urethral Strictures

Advanced Functional Materials, EarlyView.
Joule‐assisted nanotherapeutic urethral stent harnesses a smart, biodegradable magnesium stent to orchestrate spatiotemporal theragenerative therapy for urethral strictures. Magnetically induced Joule heating enables on‐demand drug release and bacterial ablation, while simultaneously guiding urothelial regeneration.

Dynamic Predictions of Postoperative Complications from Explainable, Uncertainty-Aware, and Multi-Task Deep Neural Networks [PDF]

arXiv, 2020
Accurate prediction of postoperative complications can inform shared decisions regarding prognosis, preoperative risk-reduction, and postoperative resource use. We hypothesized that multi-task deep learning models would outperform random forest models in predicting postoperative complications, and that integrating high-resolution intraoperative ...

Self-explaining Hierarchical Model for Intraoperative Time Series [PDF]

arXiv, 2022
Major postoperative complications are devastating to surgical patients. Some of these complications are potentially preventable via early predictions based on intraoperative data. However, intraoperative data comprise long and fine-grained multivariate time series, prohibiting the effective learning of accurate models.

Complications of radical and partial nephrectomy for renal cell carcinoma up to 7 cm [PDF]

Vojnosanitetski Pregled, 2017
Background/Aim. Renal cell carcinoma (RCC) is the third most frequent urological carcinoma. Radical nephrectomy (RN) is considered as the gold standard in the treatment of localized RCC, but recently the use of minimally invasive techniques are more ...

Dexamethasone Delivery via Amphiphilic, Low‐swelling Hydrogels Treats Postoperative Inflammation in Cervical Spine Applications

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
DexaPatch, an implantable, low‐swelling amphiphilic hydrogel system containing dexamethasone‐PLGA microparticles, is developed and characterized for sustained local steroid release to reduce postoperative inflammation in tight surgical spaces. DexaPatch significantly reduces postoperative edema and fibrosis in a rabbit model of anterior spinal surgery,
