Article Abstract
This article describes a ureter-sparing procedure used to treat lymph node metastases with SBRT. We delivered 35 Gy in 5 fractions of 7 Gy to patients with lesions located less than 7 mm from the ureters using a urography CT scan for planification. Two dosimetry plans were created, one using a CT scan urography-based contour and the other using the native phase. PTV coverage were not statistically different but this technique was able to significantly reduce median delivered Dmax to the ureters. These preliminary results demonstrate the feasibility of locating the ureters in a planning CT scan to protect them.

Objective: To describe the use of transcorneal iris photocoagulation (TCIP) to improve intraocular visualization of intended incision lines, reduce hemorrhage, and facilitate excision of pigmented iridal tumors in four canine eyes and one feline eye.
Materials And Methods: A Rhodesian Ridgeback (treated bilaterally), a German Shepherd, a Labrador Retriever, and a Scottish Fold underwent sector iridectomy due to rapidly growing, pigmented, raised, iridal tumors affecting 1/4-1/3 of the iris circumference (3- to 4-clock hours). A diode laser was used to delineate the intended sector iridectomy incision lines, approximately 1-2 mm away from the grossly visible tumor margins, with the aim of improving visualization to achieve tumor-free margins and reduce tissue handling/trauma.
Digital Cueing With Laser Shoes Does Not Improve Walking in Parkinson's Disease: Evidence Across Disease Severity and Freezing Status.

Background: Gait impairment in Parkinson's disease (PD) occurs early and pharmaceutical interventions do not fully restore this function. Visual cueing has been shown to improve gait and alleviate freezing of gait (FOG) in PD. Technological development of digital laser shoe visual cues now allows for visual cues to be used continuously when walking.

Background: This study aimed to explore the barriers and facilitators of implementing rehabilitation interventions for visual field loss due to stroke.
Methods: The study was a qualitative exploration using one-to-one interviews coded using template analysis and the COM-B a-priori framework. Participants were five occupational therapists from hospital (n=4) and community (n=1) National Health Service (NHS) stroke care settings in England.
The Role of Deep Cerebral Tracts in Predicting Postoperative Aphasia: An nTMS-Based Investigation of the Corticothalamic Fibers.

Postoperative aphasia (POA) is a common complication in patients undergoing surgery for language-eloquent lesions. This study aimed to enhance the prediction of POA by leveraging preoperative navigated transcranial magnetic stimulation (nTMS) language mapping and diffusion tensor imaging (DTI)-based tractography, incorporating deep learning (DL) algorithms. One hundred patients with left-hemispheric lesions were retrospectively enrolled (43 developed postoperative aphasia, as the POA group; 57 did not, as the non-aphasia (NA) group).

Background: The teaching of occlusal splint therapy in dental education is evolving with the integration of digital workflows. Although digital tools offer operational advantages, conventional methods remain pedagogically relevant. Understanding students' perceptions of both approaches is essential for guiding curriculum innovation.
