157 Background: There is increasing appreciation for the insight provided by combining low-burden home-based remote digital measurements with patient and observer reported outcomes. In this study, we assessed perspectives of cancer patients and their caregivers on the utility of a mobile app combined with a smartwatch for collection of specific outcomes and to provide clinically actionable data. Methods: In a decentralized clinical trial we consented and enrolled (10/12/2020-4/30/2021) dyads that consisted of a cancer patient and their informal caregiver. All participants had to own an Apple iPhone 6 or higher. Patients were provided with an Apple watch 3 or 4 and downloaded a patient informed mobile app (DigiBioMarC). Caregivers only download a caregiver informed mobile app (TOGETHERCare). Participants were asked to use their respective app for 28 days during which time specific surveys and activity requests were delivered through the mobile app; digital measures of physical activity were collected via the smartwatch. At the end of the app usage period, questions were asked in a video interview about the patient and caregiver perspectives on use of their respective apps and what they believed could be impacted if their doctor were to receive the app information. Respondents could select Strongly Agree, Agree, Neutral, Disagree, or Strongly Disagree. Results: Fifty-four dyads were enrolled; four were unable to continue due to a decline in health. Questions were drafted and IRB approved in time to be asked of 45 dyads. The Table lists some results and the percent of respondents that selected Strongly Agree or Agree. Conclusions: Patients and caregivers reported that both apps would encourage them to take better care of themselves/be more physically active and would improve emotional wellbeing. A high proportion of respondents also felt the apps would improve communication with their doctor and provide early important information for the doctor to act upon compared to usual care. Additional work in a large randomized trial is planned to evaluate specific care outcomes. [Table: see text]

Electroconvulsive therapy (ECT) is effective in the treatment of treatment-resistant major depression. The fear of cognitive impairment after ECT often deters patients from choosing this treatment option. There is little reliable information regarding the effects of ECT on overall cognitive performance, while short-term memory deficits are well known but not easy to measure within clinical routines. In this pilot study, we examined ECT recipients’ pre- and posttreatment performances on a digital ascending number tapping test. We found that cognitive performance measures exhibited good reproducibility in individual patients and that ECT did not significantly alter cognitive performance up to 2 hours after this therapy was applied. Our results can help patients and physicians make decisions regarding the administration of ECT. Digital measurements are recommended, especially when screening for the most common side effects on cognitive performance and short-term memory.

This study aims to compare the impact of buccal and lingual brackets on the accuracy of dental arch data acquired by 4 different digital intraoral scanners. Two pairs of dental casts, one with buccal brackets and the other with lingual brackets, were used. Digital measurements of the 3D images were compared to the actual measurements of the dental models, which were considered standard values. The horizontal measurements included intercanine widths and intermolar widths. The Mann–WhitneyUtest was performed for comparisons. iTero® and Trios® both showed high accuracy with relatively small maximum deviation of measurements. iTero showed a significantly higher accuracy in most of the arch width measurements on the buccal bracket model than on the lingual model (P<0.05). Zfx IntraScan® and E4D Dentist® produced maximum deviations of more than 2 mm from both the buccal and the lingual bracket models. After comparing the degree of distortion of the arch on the digital scans with actual measurements of the same models, iTero and Trios proved to be excellent in terms of trueness and precision. Nevertheless, digital intraoral scanners should be used more cautiously in arches with lingual brackets than in those with buccal brackets.
