The quality and the extent of intra-abdominal visualization are critical to a laparoscopic procedure. Currently, a single laparoscope is inserted into one of the laparoscopic ports to provide intra-abdominal visualization. The extent of this field of view (FoV) is rather restricted and may limit efficiency and the range of operations. Here we report a trocar-camera assembly (TCA) that promises a large FoV, and improved efficiency and range of operations. A video stitching program processes video data from multiple miniature cameras and combines these videos in real-time. This stitched video is then displayed on an operating monitor with a much larger FoV than that of a single camera. In addition, we successfully performed a standard and a modified bean drop task, without any distortion, in a simulator box by using the TCA and taking advantage of its FoV which is larger than that of the current laparoscopic cameras. We successfully demonstrated its improved efficiency and range of operations. The TCA frees up a surgical port and potentially eliminates the need of physical maneuvering of the laparoscopic camera, operated by an assistant.

Background: Identifying strategies to engage with potential participants is critical for efficient enrollment in Alzheimer's Disease (AD) trials. Previous studies link faster speed of first contact with successful phone interview completion for Major Depressive Disorder (MDD) participants. This has not been examined in AD participants.

Background: In 2020, we developed LABPSI, a cognitive stimulation web lab. Usability analysis in MCI and healthy participants have already been studied, and currently, we performed it with acquired brain injuries (ABI) participants, as they can rehabilitate their cognitive symptoms and prevent the progression to dementia. Usability can be considered the ease of use of a certain product for a specific aim by a particular population.

Background: The evaluation of mHealth interventions often lacks detailed process evaluation data. This study presents the design and results of a process evaluation for the Wellness Enhancement for Caregivers (WECARE) program, an mHealth intervention designed to improve caregiving skills and psychosocial wellbeing of Chinese American dementia caregivers. This evaluation focused on understanding the acceptance, engagement, and the barriers and facilitators influencing behavioral changes among participants, offering valuable feedback for program refinement and dissemination.

Background: It has been validated that dementia can be alleviated by talk therapy. While general large language models (LLMs) have the potential for talk therapy and dementia treatment, customized LLMs resembling a mental-health therapist can be more professional and powerful. We introduced an LLM solution designed for tailored mental health support for future dementia care.
