Endogenous cortical fluctuations captured by electroencephalograms (EEGs) reflect activity in large-scale brain networks that exhibit dynamic patterns over multiple time scales. Developmental changes in the coordination and integration of brain function leads to greater complexity in population level neural dynamics. In this study we examined multiscale entropy, a measure of signal complexity, in resting-state EEGs in a large (N = 405) cross-sectional sample of children and adolescents (9-16 years). Our findings showed consistent age-dependent increases in EEG complexity that are distributed across multiple temporal scales and spatial regions. Developmental changes were most robust as the age gap between groups increased, particularly between late childhood and adolescence, and were most prominent over fronto-central scalp regions. These results suggest that the transition from late childhood to adolescence is characterized by age-dependent changes in the underlying complexity of endogenous brain networks.
Upper airway resistance syndrome (UARS) is a sleep related breathing disorder that was first described in 1993. This goal of this study is to determine the efficacy of surgical intervention for UARS.

Systematic review of the literature and a case series of UARS patients at a large integrated healthcare system. Meta-analysis was performed.

For the systematic review, 971 abstracts were reviewed and 3 articles were included, yielding 49 subjects. All of the included studies were of level 3 or 4 evidence. Significant improvement in Epworth Sleepiness Scale (ESS) score was noted after surgery in two level 4 studies. No significant change in ESS was noted in one level 3 study. ASN-002 research buy Our retrospective chart review of eleven UARS patients compared preoperative and postoperative ESS scores, as well as sleep study data. Patients underwent a variety of surgical procedures. Our findings show a significant improvement in mean ESS scores after surgery, from 11.0 (±3.5) to 7.0 (±4.8) with p=0.01, though no difference in apnea hypopnea index (AHI) and respiratory disturbance index (RDI) were identified. Meta-analysis was performed on 2 studies from the systematic review and our cases series data. UARS surgery showed a mean change in ESS of -5.89 (95% CI, -8.29 to -3.50).

This systematic review, meta-analysis and retrospective case series indicate that surgery may improve ESS scores in patients with UARS. AHI and RDI are unlikely to be impacted by surgery.

Sudden sensorineural hearing loss (SSNHL) is commonly encountered in otolaryngologic practice. SARS-CoV-2 infection is typically marked by respiratory symptoms although neurologic manifestations of the disease have also been described.

We want to measure the incidence and clinical aspects of persons exhibiting in otolaryngology clinic (OC) with SSNHL during the COVID-19 widespread and in the constant interval of previous year.

We retrospectively inspected the medical information for admissions to OC in Eskisehir, Turkey, during the COVID-19 widespread to describe the patients SSNHL. Clinical knowledge was saved for each subject and corresponded with that of SSNHL subjects demonstrating in 2019.

Between 1 April and 30 September 2020, 68 patients admitted to OC for SSNHL; in 2019, there were 41 subjects, for an incidence rate ratio of 8.5 per 100.000 (95% CI 1.02-2.92) for the 2020 cohort. Of the 2020 group, forty-one patients (60.3%) presented with active or recent symptoms consistent with COVID-19 infection, compared with four (9.8%) in 2019 (p<0.001). Furthermore, subjects in 2020 group were younger (-15.5years, p=0.0141) than 2019 group and demonstrated prolonged interim (+1.7days, p<0.001) between SSNHL initiation and OC petition.

We detected increased incidence of SSNHL during the COVID-19 widespread compared to the same interval of the prior year; 60.3% of subjects confronting with SSNHL had signs that were harmonious with COVID-19.

Accurate threat appraisal is central to survival. In the case of the coronavirus pandemic, accurate threat appraisal is difficult due to incomplete medical knowledge as well as complex social factors (e.g., mixed public health messages). The purpose of this study was to evaluate the degree to which individuals accurately perceive COVID-19 infection rates and to explore the role of COVID-19 threat perception on emotional and behavioral responses both cross sectionally and prospectively.

A community sample (N=249) was assessed using online crowdsourcing and followed for one month. COVID-19 threat appraisal was compared with actual COVID-19 infection rates and deaths at the time of data collection in each participant's county and state. It was predicted that actual versus perceived COVID-19 infection rates would only be modestly associated. Relative to actual infection rates, perceived infection rates were hypothesized to be a better predictor of COVID-related behaviors, distress, and impairment.

Findings indicated that relative to actual infection, perceived infection was a better predictor of COVID-related outcomes cross sectionally and longitudinally. Interestingly, actual infection rates were negatively related to behaviors cross sectionally (e.g., less stockpiling). Prospectively, these variables interacted to predict avoidance behaviors over time such that the relationship between perceived infection and avoidance was stronger as actual infection increased.

These data suggest that perceived COVID-19 infection is significantly associated with COVID-related behaviors, distress and impairment whereas actual infection rates have a less important and perhaps even paradoxical influence on behavioral responses to the pandemic.
