Hippocampal oscillations are dynamic, with unique oscillatory frequencies present during different behavioral states. To examine the extent to which these oscillations reflect neuron engagement in distinct local circuit processes that are important for memory, we recorded single cell and local field potential activity from the CA1 region of the hippocampus as rats performed a context-guided odor-reward association task. We found that theta (4–12 Hz), beta (15–35 Hz), low gamma (35–55 Hz), and high gamma (65–90 Hz) frequencies exhibited dynamic amplitude profiles as rats sampled odor cues. Interneurons and principal cells exhibited unique engagement in each of the four rhythmic circuits in a manner that related to successful performance of the task. Moreover, principal cells coherent to each rhythm differentially represented task dimensions. These results demonstrate that distinct processing states arise from the engagement of rhythmically identifiable circuits, which have unique roles in organizing task-relevant processing in the hippocampus.DOI: http://dx.doi.org/10.7554/eLife.09849.001
In a cohort of patients at a tertiary care "safety-net" center serving a low-income population, compliance to SCIT was found to be overall high but lower in the Medicaid population.
Objectives: Evidence shows that scribes can improve provider efficiency and satisfaction in several settings, but is mixed on whether scribes improve patient satisfaction. We studied whether scribes improved patient satisfaction in an academic otolaryngology clinic. Methods: The authors performed a retrospective review of patient responses to the Press Ganey survey between 12/2016 and 12/2017. Their responses about satisfaction with the provider and wait times were examined. Three providers worked with scribes during this year; each spent six months with a scribe and six without. The authors compared survey responses from periods with and without scribes using the Fischer exact test. Average overall provider ratings were compared using the Student’s t-test. Results: A total of 87 patients filled out Press Ganey surveys for the 3 providers over the year: 54 for visits without scribes, and 33 for visits with scribes. Fischer exact analysis demonstrated no significant difference in satisfaction with providers and wait times for both individual providers and all providers combined (all P > .05). There was also no difference in patients’ likelihood of recommending the provider’s office ( P = .91). Overall provider rating (0-10 scale) was high without scribes (9.48 ± 1.06) and was unchanged by the presence of scribes (9.53 ± 0.8) ( P = .97). Conclusion: Patient satisfaction with wait times and providers was high overall and was not affected by the presence of a medical scribe.
Objectives For more than a century, pediatric obstructive sleep apnea (OSA) was associated with failure to thrive. However, that association has faded over the last few decades. A 21st century child with OSA is much more likely to be overweight than underweight. This raises the question: Has pediatric OSA changed over time, or has the rise of childhood obesity in the United States created a new, separate disease? This literature review explores the historical shift in the relationship between weight and OSA, and the associated changes in treatment. Results We demonstrate a clear transition in the prevalence of failure to thrive and obesity in the OSA literature in the mid‐2000s. What is less clear is whether these two clinical phenotypes should be considered two distinct diseases, or whether subtle differences in one set of pathophysiologic pathways—adenotonsillar hypertrophy, altered inflammation, and increased energy expenditure—can lead to divergent metabolic outcomes. More research is needed to fully elucidate the pathophysiology of OSA in children with obesity. Conclusions We may need new and different treatments for obesity‐associated OSA as adenotonsillectomy—which is effective at reversing failure to thrive in OSA—is not as effective at treating OSA in children with obesity. One option is drug‐induced sleep endoscopy, which could personalize and improve surgical treatment of OSA. There is some evidence that therapies used for OSA in adults (e.g., weight loss and positive airway pressure) are also helpful for overweight/obese children with OSA.

At this time, stronger conclusions cannot be made about the therapies investigated because there are many methodology limitations of the studies analyzed. However, our results suggest merit for these treatments as adjuvant therapies that can enhance analgesia and decrease requirements of controversial medications. Honey and acupuncture have the greatest amount of evidence for postoperative pain and nausea; however, all interventions examined were cost-effective and safe. We recommend against hydrogen peroxide rinses and chewing gum. Laryngoscope, 2625-2634, 2018.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
