Project description:Routine video recording of the colonoscopy examination has been proposed as a simple and easy to implement method that could improve the quality of colonoscopy. The purpose of this study is to investigate whether implementation of routine video recording of screening colonoscopy withdrawal is effective as a means of supporting quality performance of colonoscopy. The study will be performed in 8 screening centers within the framework of a national colonoscopy screening program in Poland (the Polish Colonoscopy Screening Platform; PCSP). Individuals aged 55-64 years are eligible to participate in the PCSP. In the run-in period colonoscopy quality measures will be monitored through a dedicated joint database. Then eligible screening centres will be randomly assigned in a 1:1 ratio to the video recording group or the control group. Screening centres assigned to the video recording group will receive videorecorders and DVDs and will be asked to video record all screening colonoscopies (only withdrawal). Control group will be allowed to record colonoscopies on demand only. Then , the colonoscopy quality measures will again be monitored through a dedicated joint database. All the recorded DVDs will be reviewed to verify ceacal intubation and withdrawal time by the PCSP team.

Project description:PurposeSurgeons' skill in the operating room is a major determinant of patient outcomes. Assessment of surgeons' skill is necessary to improve patient outcomes and quality of care through surgical training and coaching. Methods for video-based assessment of surgical skill can provide objective and efficient tools for surgeons. Our work introduces a new method based on attention mechanisms and provides a comprehensive comparative analysis of state-of-the-art methods for video-based assessment of surgical skill in the operating room.MethodsUsing a dataset of 99 videos of capsulorhexis, a critical step in cataract surgery, we evaluated image feature-based methods and two deep learning methods to assess skill using RGB videos. In the first method, we predict instrument tips as keypoints and predict surgical skill using temporal convolutional neural networks. In the second method, we propose a frame-wise encoder (2D convolutional neural network) followed by a temporal model (recurrent neural network), both of which are augmented by visual attention mechanisms. We computed the area under the receiver operating characteristic curve (AUC), sensitivity, specificity, and predictive values through fivefold cross-validation.ResultsTo classify a binary skill label (expert vs. novice), the range of AUC estimates was 0.49 (95% confidence interval; CI = 0.37 to 0.60) to 0.76 (95% CI = 0.66 to 0.85) for image feature-based methods. The sensitivity and specificity were consistently high for none of the methods. For the deep learning methods, the AUC was 0.79 (95% CI = 0.70 to 0.88) using keypoints alone, 0.78 (95% CI = 0.69 to 0.88) and 0.75 (95% CI = 0.65 to 0.85) with and without attention mechanisms, respectively.ConclusionDeep learning methods are necessary for video-based assessment of surgical skill in the operating room. Attention mechanisms improved discrimination ability of the network. Our findings should be evaluated for external validity in other datasets.

Project description:We found evidence from two experiments that a simple set of gestural techniques can improve the experience of online meetings. Video conferencing technology has practical benefits, but psychological costs. It has allowed industry, education and social interactions to continue in some form during the covid-19 lockdowns. But it has left many users feeling fatigued and socially isolated, perhaps because the limitations of video conferencing disrupt users’ ability to coordinate interactions and foster social affiliation. Video Meeting Signals (VMS™) is a simple technique that uses gestures to overcome some of these limitations. First, we carried out a randomised controlled trial with over 100 students, in which half underwent a short training session in VMS. All participants rated their subjective experience of two weekly seminars, and transcripts were objectively coded for the valence of language used. Compared to controls, students with VMS training rated their personal experience, their feelings toward their seminar group, and their perceived learning outcomes as significantly higher. Also, they were more likely to use positive language and less likely to use negative language. A second, larger experiment replicated the first, and added a condition where groups were given a version of the VMS training but taught to use emoji response buttons rather than gestures to signal the same information. The emoji-trained groups did not experience the same improvement as the VMS groups. By exploiting the specific benefits of gestural communication, VMS has great potential to overcome the psychological problems of group video meetings.

Project description:Induced pluripotent stem cells (iPSCs) are a promising source for cell-based therapy to treat Parkinson's disease (PD), in which midbrain dopaminegic (DA) neurons progressively degenerate. However, long-term analysis of human iPSC-derived DA neurons in primate PD models has never been performed. Here we show that DA progenitor cells derived from iPSCs of both healthy individuals and PD patients survived well in the brains of PD model primates and improved animal behavior. Magnetic resonance and positron emission tomography were useful to monitor the survival and function of the DA neurons. Score-based and video-recording analyses revealed an increase in spontaneous movement of the monkeys after transplantation. Histological studies showed that the mature DA neurons extended dense neurites into the host striatum. In addition, we never observed tumor formation for two years. Thus, this preclinical study using primate models indicates that human iPSC-derived DA progenitors are clinically applicable to treat PD patients.

Project description:Cancer patients about to begin chemotherapy receive large amounts of information regarding their prognosis, how chemotherapy improves their prognosis, and the usual side effects of the chemotherapy during their first visit to the oncologist. Prior studies have documented that less than half of this information is retained after the visit, making it difficult for patients to participate in their care and difficult for them to enlist the help of their social support. The MiVideo project allows the physician to create a custom 5-minute summary video summary of a pre-chemotherapy clinic visit and upload it to a secure web site. The video will emphasize the major points of the forty-five minute office discussion, allowing patients to review the physicians’ recommendations and share the information and recommendations with others. By providing the patient with this re-cap of their visit, the investigators hope to engage them more actively in their cancer treatment. Making the information available to friends and family can also help a patient receive both intellectual and emotional support during the course of treatment. The primary endpoint of this study is improvement of patient care, not research activity.
Primary Hypothesis: Creating a 5-minute video summarizing information about diagnosis, stage, chemotherapy treatment plan, and anticipated side effects for patients starting chemotherapy for colon cancer will not significantly lengthen the pre-chemotherapy clinic visit as compared to visits that do not include video production.

Project description:This clinical trial compares an educational video intervention versus usual care of no video intervention in decreasing patient fear of a colonoscopy procedure after receiving a positive fecal immunochemical test (FIT). The lack of a follow-up colonoscopy after an abnormal FIT result is associated with an increased risk of colorectal cancer mortality, advanced-stage colorectal cancer, among other complications, compared to the completion of a follow-up colonoscopy. An educational video may reduce patient fear and increase knowledge, self-efficacy, and intent to complete a colonoscopy compared to the usual care of no video intervention.

Project description:Background: Superior cerebellar artery (SCA) aneurysms are rare. Current treatments include: direct clipping, trapping ± bypass, and endovascular methods (coiling, stenting, or flow diversion). Due to specific characteristics (wide base, location, and shape), a major challenge while dealing with SCA aneurysms is to preserve the flow of the parent artery and perforators. This video demonstrates a revascularization procedure, and clip reconstruction of a large unruptured basilar artery (BA)/SCA aneurysm performed through the subtemporal approach. Case Description: A 60-year-old woman presented with dizziness and headaches. Computed tomography angiography (CTA) and digital subtraction angiography showed a right unruptured large BA/SCA aneurysm. After multidisciplinary discussion, and considering gender, age, risk factors of the patient. Endovascular treatment was considered with a high risk of ischemic complications. Therefore, the patient was consented for a superficial temporal artery (STA)-SCA bypass through subtemporal approach followed by direct clipping/ trapping of the aneurysm. Postoperative CTA showed occlusion of the aneurysm and patency of the parent vessels. Postoperatively, the patient experienced immediate transient left mild monoparesis and right IV nerve palsy, which recovered completely at 6-months follow-up. Results: Surgical treatment of SCA aneurysms is decreasing due to the existence of endovascular therapies such as stents and flow diverters. However, some cases may necessitate surgical treatment and revascularization procedures to maintain the blood flow of the parent artery and to treat the previous lesion. Conclusion: The STA-SCA bypass through the subtemporal approach is a feasible option to maintain the blood flow of the parent artery in cases of SCA requiring surgical treatment and trapping/direct clipping of the aneurysm.

Project description:Pancreaticobiliary maljunction (PBM) is associated with the development of neoplasms of bile ducts. Cholecystectomy with diversion of the biliary-pancreatic flow is considered the treatment of choice. To describe the surgical treatment employed for a patient with Komi's type 2 PBM and its long-term results. Laparoscopic common bile duct exploration, intraoperative cholangioscopy, and Roux-en-Y hepatico-jejunostomy were performed. Postoperative evolution was satisfactory. The patient was discharge 72 hours after the surgery. There was no associated morbidity. At 62-month follow-up, clinical examination, laboratory tests, and imaging studies confirmed an adequate patency of bilio-enteric anastomosis. The surgical approach employed was effective and safe, with satisfactory long-term results.
