Recent studies have shown the success of face recognition using low resolution prosthetic vision, but it requires a zoomed-in and stably-fixated view, which will be challenging for a user with the limited resolution of current prosthetic vision devices. We propose a real-time object detection and tracking system capable of fixating human faces. By integrating both static and temporal information, we are able to improve the robustness of face localization so that it can fixate on faces with large pose variations. Our qualitative and quantitative results demonstrate the viability of supplementing visual prosthetic devices with the ability to visually fixate objects automatically, and provide a stable zoomed-in image stream to facilitate face and expression recognition.

Background: Prosthesis users often rely on vision to monitor the activity of their prosthesis, which can be cognitively demanding. This compensatory visual behaviour may be attributed to an absence of feedback from the prosthesis or the unreliability of myoelectric control. Unreliability can arise from the unpredictable control due to variations in electromyography signals that can occur when the arm moves through different limb positions during functional use.

Background: Rapid deployment aortic valve replacement (RDAVR) has been widely adopted, but concerns about postoperative paravalvular leak (PVL) associated with its use remain. PVL is linked to an increased risk of long-term mortality; however, there is no consensus on its treatment.
Case Presentation: Case 1: A 76-year-old female with severe aortic stenosis underwent RDAVR via median sternotomy.

Remote sighted assistance (RSA) has emerged as a conversational technology aiding people with visual impairments (VI) through real-time video chat communication with sighted agents. We conducted a literature review and interviewed 12 RSA users to understand the technical and navigational challenges faced by both agents and users. The technical challenges were categorized into four groups: agents' difficulties in orienting and localizing users, acquiring and interpreting users' surroundings and obstacles, delivering information specific to user situations, and coping with poor network connections.

Importance: Public awareness of oral cancer is crucial for prevention, early detection, and improved survival rates. Knowledge gaps in Middle Eastern and North African countries and areas for public education need to be assessed.
Objective: To evaluate public knowledge and awareness of oral cancer, including risk factors, signs and symptoms, and protective measures, in Middle Eastern and North African countries.
