This paper describes the design and implementation of SAPPHIRE--a novel middleware and software development kit for stream programing on a heterogeneous system of multi-core multi-CPUs with optional hardware accelerators such as graphics processing unit (GPU). A stream program consists of a set of tasks where the same tasks are repeated over multiple iterations of data (e.g., video frames). Examples of such programs are video analysis applications for computer-aided diagnosis and computer-assisted surgeries. Our design goal is to reduce the implementation efforts and ease collaborative software development of stream programs while supporting efficient execution of the programs on the target hardware. To validate the toolkit, we implemented EM-Automated-RT software with the toolkit and reported our experience. EM-Automated-RT performs real-time video analysis for quality of a colonoscopy procedure and provides visual feedback to assist the endoscopist to achieve optimal inspection of the colon during the procedure. The software has been deployed in a hospital setting to conduct a clinical trial.

Background: Mental health remains among the top 10 leading causes of disease burden globally, and there is a significant treatment gap due to limited resources, stigma, limited accessibility, and low perceived need for treatment. Problem Management Plus, a World Health Organization-endorsed brief psychological intervention for mental health disorders, has been shown to be effective and cost-effective in various countries globally but faces implementation challenges, such as quality control in training, supervision, and delivery. While digital technologies to foster mental health care have the potential to close treatment gaps and address the issues of quality control, their development requires context-specific, interdisciplinary, and participatory approaches to enhance impact and acceptance.

Objectives: We previously did a randomized clinical trial of lobectomy by VATS or thoracotomy for early-stage lung cancer and found that patients who underwent VATS had less postoperative pain and better quality of life compared with thoracotomy. VATS has since been regarded the preferred surgical method for early-stage lung cancer. It is assumed that long-term survival is not influenced by surgical approach, but this assumption primarily rests on non-randomized comparative studies.

Department of Thoracic Surgery, Shanghai Fourth People's Hospital, School of Medicine, Tongji University, Shanghai, China.
Background: Accurate preoperative positioning is the key to the success of thoracoscopic surgery for small pulmonary nodules. There are many methods for locating pulmonary nodules in clinical practice, but there are currently few research reports on the value of medical adhesive localization.
Objective: To compare the clinical value of two positioning methods, medical adhesive and metal spring coil, in the preoperative application of VATS through retrospective analysis.
Background: Although varieties in chewing patterns are essential for the transformation of food in mouth and thereby its sensorial perception, there are few reports that show the effect of chewing frequency on food oral processing and its properties.
Objective: The current study tested whether consciously controlled chewing frequency influences the oral processing of habitually consumed foods and their sensory analysis.
Method: Chewing behaviour was analysed during the mastication of mushed potato samples by 20 participants in two separate test sessions, in which they were instructed to chew the sample in their habitual manner (free chewing test) or follow a preprogrammed video animation displayed on a screen, wich guided them to maintain a constant chewing frequency (F-const chewing test).
Improved Visualization of Oropharyngeal Tumors Using Simple Maneuvers During Flexible Endoscopy.
Ann Otol Rhinol Laryngol
January 2025
Department of Otolaryngology-Head and Neck Surgery, Stanford University School of Medicine, Stanford, CA, USA.
Objectives: To describe patient positioning maneuvers that optimize visualization of the oropharynx during flexible endoscopy.
Methods: An institutional database of videos obtained from 2021 to 2023 during flexible endoscopy of patients with oropharyngeal carcinoma (OPC) was reviewed. Patients seen outside the specialty head and neck clinic, those with tonsillar primary tumors, and those only with videos of fiberoptic swallowing evaluations were excluded.
