Importance: Prior research found that pediatric direct-to-consumer (DTC) telemedicine visits are associated with more antibiotic prescribing than in-person primary care visits. It is unclear whether this difference is associated with modality of care (telemedicine vs in-person) or with the context of telemedicine care (primary care vs not primary care).
Objective: To compare antibiotic management during telemedicine visits with primary care practitioners (PCPs) vs commercial direct-to-consumer (DTC) telemedicine companies for pediatric acute respiratory tract infections (ARTIs).

Background: Telemedicine delivered from primary care practices became widely available for children during the COVID-19 pandemic.
Objective: Focusing on children with a usual source of care, we aimed to examine factors associated with use of primary care telemedicine.
Methods: In February 2022, we surveyed parents of children aged ≤17 years on the AmeriSpeak panel, a probability-based panel of representative US households, about their children's telemedicine use.
Pediatric acute respiratory tract infections (ARTIs) were a common reason for commercial direct-to-consumer (DTC) telemedicine use before the COVID-19 pandemic, but the factors associated with this use are unknown. To identify child and family factors associated with use of commercial DTC telemedicine for ARTIs in 2018-2019. We performed a retrospective cohort analysis of claims data from the Optum Clinformatics Data Mart Database.

We sought to characterize the relative contribution of practice-based telemedicine versus commercial DTC telemedicine models in provision of children's telemedicine from 2018 through 2021.
Methods: Using January 2018 to September 2021 data from Optum's de-identified Clinformatics® Data Mart Database, we identified telemedicine visits by children ≤17, excluding preventive visits and visits to specialists, emergency departments, and urgent care.

The vestibular system contributes to regulating sympathetic nerve activity and blood pressure. Initial studies in decerebrate animals showed that neurons in the rostral ventrolateral medulla (RVLM) respond to small-amplitude (<10°) rotations of the body, as in other brain areas that process vestibular signals, although such movements do not affect blood distribution in the body. However, a subsequent experiment in conscious animals showed that few RVLM neurons respond to small-amplitude movements.

In this study, we tested the hypothesis that feedforward cardiovascular responses occur when a passive (imposed) 60° head-up tilt is anticipated, such that changes in heart rate and carotid artery blood flow (CBF) commence prior to the onset of the rotation. A light cue preceded head-up tilts by 10 sec, and heart rate and CBF were determined for 5-sec time periods prior to and during tilts.

We recently demonstrated in both decerebrate and conscious cats that labyrinthine and hindlimb inputs converge onto vestibular nucleus neurons. The pontomedullary reticular formation (pmRF) also plays a key role in postural control, and additionally participates in regulating locomotion.
