Abstract Objective This study was undertaken to describe patterns of benzodiazepine use as first‐line treatment status epilepticus (SE) and test the association doses with response second‐line agents in patients enrolled Established Status Epilepticus Treatment Trial (ESETT). Methods Patients refractory an adequate dose benzodiazepines for SE were ESETT. Choice benzodiazepine, given prior administration agent, route administration, setting, patient weight characterized. These compared...

Importance Low-dose computed tomography (LDCT) lung screening has been shown to reduce cancer mortality. Significant incidental findings (SIFs) have widely reported in patients undergoing LDCT screening. However, the exact nature of these SIF not described. Objective To describe SIFs arm National Lung Screening Trial and classify as reportable or referring clinician (RC) using American College Radiology’s white papers on findings. Design, Setting, Participants This was a retrospective case...

Abstract Introduction While telemedicine usage has increased due to the COVID-19 pandemic, there remains little consensus about how spine surgeons perceive virtual care. The purpose of this study was explore international perspectives providers on challenges and benefits telemedicine. Methods Responses from 485 members AO Spine were analyzed, covering provider perceptions All questions optional, blank responses excluded analysis. Results leading reported by decreased ability perform physical...

It is unknown how often and early EEG obtained in patients presenting with status epilepticus. The Established Status Epilepticus Treatment Trial enrolled benzodiazepine-refractory seizures randomized participants to fosphenytoin, levetiracetam, or valproate. use of EEG, including frequency electrographic seizures, was determined participants.Secondary analysis 475 enrollments at 58 hospitals determine the performed within 24 hours presentation. type, prevalence characteristics associated...

Previous studies have raised concerns regarding neurodevelopmental impacts of early exposures to general anesthesia and surgery. Electroencephalography (EEG) can be used study ontogeny brain networks during infancy. As a substudy an ongoing study, we examined measures functional connectivity in awake infants with prior prolonged anesthetic control infants. EEG was assessed using debiased weighted phase lag index at source sensor levels graph theoretical for resting state activity the (n = 26...

Objective: To evaluate recovery from neuromuscular blockade in infants using Train-of-Four nerve stimulation. Study Design: Ulnar stimulation was used to evoke thumb twitch and reported as a ratio. Thumb also recorded visually real-time. The primary outcome time near of muscle function (Train-of-Four ratio >70%). Secondary analyses were greater degrees recovery, >80%, 90%), the sensitivity accelerometry versus visual thumb-twitch clinical variates assess safety. Results: Patients enrolled...

Background Atrial fibrillation/flutter (AF) after transient ischemic attack (TIA) has not been well studied. We compared the likelihood of new AF diagnosis stroke versus TIA. Methods and Results The POINT (Platelet-Oriented Inhibition in New TIA Minor Ischemic Stroke) trial enrolled adults within 12 hours minor or high-risk Our exposure was index event type (ischemic TIA). primary analysis used original definition (resolution symptoms/signs). In secondary analyses, cases with infarction on...

6597 Background: We prospectively assessed financial burden (FB) due to treatment costs among patients with colorectal cancer (CRC) recruited by NCI Community Oncology Research Program (NCORP) sites. Methods: Patients newly diagnosed CRC treated curative intent enrolled through NCORP sites and completed the FACIT Comprehensive Score for Financial Toxicity (COST) instrument at 0-, 3, 6, 12 months. Higher COST score (range 0-44) indicates greater well-being. Effects of demographic, clinical,...

1518 Background: Cancer therapy costs continue to rise, resulting in FB. FB CRC treated with curative intent remains unexplored, particularly the community oncology setting. We assess baseline and 3-month change, including predictors. Methods: Patients newly diagnosed were enrolled through NCI Community Oncology Research Program (NCORP) Sites a longitudinal study completed validated FACIT Comprehensive Score for Financial Toxicity (COST) instrument at 3 months. Higher COST score (range 0-44)...
