Quality of Information Available on YouTube Videos Pertaining to Bariatric Surgery

YouTube is one of the most frequently used online sources providing easy access to health information with a large, diverse, and searchable video library. However, an unregulated policy and lack of peer-review process are important disadvantages. Accordingly, while based on thousands of surgical, animated, oral presentation and patient-experience videos, the information provided by YouTube videos is considered questionable in terms of quality, accuracy and credibility.

Assessment of solid tumor oncology perception and knowledge gain in internal medicine (IM) residents through oncology video library: Educational intervention in progress.

e23000 Background: ACGME and internal surveys performed at the University of North Carolina (UNC) demonstrate that IM residents have historically been dissatisfied with their inpatient oncology experience. Other institutions have demonstrated that a resident oncology video library is feasible and effective in improving clinical knowledge, but formal protected time for module use limited engagement. We created an oncology video library targeted to the resident learner. To enhance impact, we incorporated dedicated time during elective rotations to access the modules. Methods: We performed a pre-survey using a Likert scale to assess resident knowledge perception of solid tumor cancers. We designed a curriculum based on the ABIM blueprint and those cancers frequently encountered on service. We filmed 21 videos of UNC oncologists discussing content they selected for the resident learner. To improve engagement, we provided a half-day of independent study during their outpatient oncology elective. As this study is ongoing, we plan to conduct a post-survey and post-test to evaluate long-term knowledge acquisition. Results: Twenty-seven of the 85 IM residents completed the pre-survey. Eleven (40.8%) reported feeling extremely or somewhat satisfied with inpatient oncology teaching; the remainder felt neutral (29.6%), somewhat (25.9%) or extremely dissatisfied (3.7%). Among oncologic emergencies, most residents felt comfortable managing hypercalcemia (88.9%) and cord compression (55.6%), but not SVC syndrome (29.6%). Prior to implementation of the videos, most reported little/no knowledge gain from their clinical rotations alone across nearly all 20 domains assessed. The only domain in which a majority (65.39%) reported some or significant knowledge gain was chemotherapy toxicities. These domains were selected as video lecture topics. In the five months since their release, each video has been viewed an average 21.5 times. The most viewed video (39 views) was on traditional chemotherapy pharmacology; the least viewed video (9 views) was on pancreas cancer. 28% of residents surveyed reported utilizing the videos, and for those who did access them, half (56.2%) felt that the time for the videos was sufficient, while the other half (43.8%) wished for more dedicated time. Conclusions: IM residents may benefit from an online video library to improve knowledge acquisition and perception of oncology rotations. However, to maximize impact, residents must be given adequate time separate from their service requirements to access the modules. This is a study in progress, and while initial data regarding video utilization appears promising, we await additional information to ascertain knowledge improvement.

Eyelid Malposition after Blepharoplasty: An Ounce of Prevention

Upper and lower eyelid blepharoplasty are common procedures performed to provide a more youthful and rejuvenated appearance. However, this seemingly straightforward procedure may result in lid malpositions, frustrating the patient and surgeon alike, which ultimately require further treatment. We review preoperative assessment pearls to avoid these lid malpositions, as well as options for treating any postoperative complications related to lid position. Many of the techniques discussed in this article, in addition to many other oculoplastic procedures, are available to view in Dr. Richard C. Allen's operative video library at: http://webeye.ophth.uiowa.edu/eyeforum/video/plastics/.

Micro-Dosing of Indocyanine Green for Intraoperative Fluorescence Cholangiography

Background: Surgery involving the biliary tree is common but has the potential for serious complications. Adjuncts such as intraoperative cholangiogram and, more recently, indocyanine green (ICG) fluorescence cholangiography, have been used to more accurately define the relevant anatomy and decrease the risk of common bile duct injury. The optimal ICG dose is unknown, but the most commonly cited dose in the literature is 2.5 mg. We describe our experience using micro-dosing of ICG as proof-of-concept for its successful use in the identification of biliary structures. Methods: A video library from a variety of hepatobiliary surgeries which included micro-dosing of ICG was compiled between 2018 and 2020. These videos were retrospectively reviewed and graded for the degree of visualization of biliary structures (complete, partial, none) and the degree of background liver fluorescence (significant, moderate, minimal). Results: Overall, 40 videos were reviewed; 70% were minimally invasive cholecystectomies. Micro-dosing was used in all patients; complete visualization was achieved in 52.5% of the patients, partial visualization in 40%, and no visualization in 7.6%. Eighty percent of patients had minimal to moderate background fluorescence. Despite ICG micro-dosing, 20% of the patients still had significant liver dye uptake. Conclusion: ICG cholangiography is an alternative to more invasive means of intraoperative imaging during biliary surgery, but the optimal dose of ICG is unknown. We have used a 0.05 mg micro-dose of ICG to successfully visualize biliary structures and reduce background liver fluorescence. This preliminary report can be used to develop further studies into whether micro-dosing of ICG is associated with improved clinical outcomes.

Initial Translation of a Dementia Caregiver Intervention Into a Mobile Health Application

Caring for a person with dementia is associated with negative outcomes. Few caregiver interventions have been implemented in community settings. Mobile technology is one method for reaching many caregivers. This project translated two empirically-supported interventions for dementia caregivers into a mobile health application. A team of clinical researchers and computer engineers developed an App called CARE-Well (Caregiver Assessment, Resources, and Education) over 6 months. The group worked closely to do the following: 1). translate interventional content to be compatible with a mobile platform; 2). create new materials; 3). determine App components that captured key intervention areas; 4). troubleshoot formatting, technology, and data security; and 5). educate each other about respective areas of expertise. We developed a beta version of the App that included: 1). assessment of caregiver stress and care recipient behavioral problems; 2). psychoeducation; 3). goal diary; 4). managing behavior problems; 5). online message forum; and 6). video library. Several challenges arose during the App development process, such as how to create navigation paths and goal lists based off users’ assessment responses, data storage and usage tracking, enlarging text, and how to ensure privacy and confidentiality in the online message forum. Our experience developing the CARE-Well App showed that translating behavioral interventions into mobile health applications is feasible and dependent upon regular communication among multidisciplinary team members. Next steps for the App include beta testing with dementia caregivers and conducting a pilot randomized trial to determine feasibility for a future trial and its effects on caregiver stress.

Research on sports action recognition system based on cluster regression and improved ISA deep network

The movements of sports athletes are complex and difficult to identify with current smart technologies. Therefore, in order to improve the sports athlete recognition rate, this paper analyze the sports action recognition system based on cluster regression and improved ISA deep network. Through literature investigation, this paper chooses ISA neural network as the basis of the algorithm. At the same time, this paper analyzes the shortcomings of traditional ISA neural network, combines the sports player’s motion recognition requirements to improve the traditional ISA neural network, and builds a sports player motion recognition system based on the improved ISA neural network algorithm. In addition, this paper uses the network data collection method to construct the sports player action video library and takes the basketball project as an example for analysis and identifies it through feature judgment. Finally, this paper builds experiments to perform model performance analysis. The research shows that the recognition rate of basketball action is greatly improved compared with the traditional algorithm model, the results verify that the improved ISA deep network proposed in this paper has significant effectiveness in the field of human behavior recognition research.
