A range of abnormal electrical activity patterns termed epileptiform discharges can occur in the brains of persons with epilepsy. These epileptiform discharges can be monitored and recorded with implanted devices that deliver therapeutic neurostimulation. These continuous recordings provide an opportunity to study the behavioral correlates of epileptiform discharges as the patients go about their daily lives. Here, we captured the smartphone touchscreen interactions in eight patients in conjunction with electrographic recordings (accumulating 35,714 h) and by using an artificial neural network model addressed if the behavior reflected the epileptiform discharges. The personalized model outputs based on smartphone behavioral inputs corresponded well with the observed electrographic data (R: 0.2-0.6, median 0.4). The realistic reconstructions of epileptiform activity based on smartphone use demonstrate how day-to-day digital behavior may be converted to personalized markers of disease activity in epilepsy

Key Points Question What is the association between cardiac surgeons’ years in practice and operative outcomes on coronary artery bypass grafting (CABG) and valve surgery? Findings In this cross-sectional study of data from early-career (<10 years) and late-career (>10 years) cardiac surgeons practicing between 2014 and 2016 in New York, a lower number of years in practice for cardiac surgeons was significantly associated with a higher risk-adjusted mortality rate in valve procedures. The risk-adjusted mortality rate was similar across different numbers of years in practice for CABG procedures. Meaning In this study, early-career status in cardiac surgeons was associated with worse surgical outcomes for valve operations, which suggests that additional complex valve surgery training in residency and mentorship guidance in early practice may be warranted.

U.S. cardiac surgeons encounter complex decision-making when treating patients with injection drug use-associated infective endocarditis (IDU-IE). We evaluated surgeons' treatment approaches for IDU-IE compared to non-IDU-IE. This is an anonymous survey of U.S. cardiac surgeons who answered hypothetical infective endocarditis (IE) clinical scenarios that varied based on patient substance use history, addiction treatment, and history of IE. Treatment approaches were classified as operative vs nonoperative.Responses were descriptively analyzed. The survey response rate was 8.7% (n = 208). Survey respondents were mostly male (85.6%) and non-Hispanic white (67.8%), but were from all regions of the United States. Surgeons reported they would operate at similar proportions for patients with native valve non-IDU-IE (63%) and IDU-IE engaged in methadone treatment (64.5%). Most surgeons reported they would operate on patients with recurrent non-IDU-IE (93.1%) compared to only 26.4% for patients with recurrent IDU-IE (P < 0.001). Most surgeons reported they would place no limits on the number of operations for patients with recurrent non-IDU-IE (73.1%), whereas 83.5% of surgeons would limit the number of surgeries for patients with recurrent IDU-IE (P < 0.001). Most respondents reported having declined to operate on patients with IDU-IE (63.5%). Cardiac surgeons are less likely to report favoring operative management for primary and recurrent infection in patients with IDU-IE, though patient engagement in methadone treatment increased the likelihood of them taking an operative approach. There is opportunity to standardize the care, including addiction treatment, of patients with IDU-IE to optimize positive short and long-term outcomes.
