Notes

Ideal triage pertaining to COVID-19 patients below limited medical assets: Continuing development of a new parsimonious device understanding forecast model as well as limit optimization making use of discrete-event sim.
Strong protections from governments (e.g., implementing best practices in suicide prevention) are urgently needed to reduce suicide behaviors during the COVID-19 pandemic.
The objective of the study was to analyze the auditory brainstem response (ABR) test results of adolescents with normal hearing threshold who have subjective tinnitus in an effort to determine the probable site of origin of tinnitus.

Among the patients who visited the outpatient clinic of the Department of Otolaryngology at our tertiary hospital from January 2016 to December 2019, adolescents aged 13-18 years with the chief complaint of unilateral subjective tinnitus and pure tone audiometry (PTA) within 25dB HL were enrolled and retrospectively reviewed. The ABR test parameters (amplitudes and latencies of waves I, III, and V and interpeak latencies [IPLs] of waves I-III, III-V, and I-V) were analyzed and compared between tinnitus ears and contralateral ears without tinnitus. Study participants were divided into the chronic tinnitus (tinnitus duration ≥6 months) and non-chronic tinnitus (tinnitus duration <6 months) groups, and the difference between the two groups was analyzed.

Ten adolescents were included in the study, and their ABR test results were reviewed. IPL III-V was significantly prolonged in tinnitus ears compared to non-tinnitus ears (p=0.035). Although other parameters were found to be statistically non-significant, there was preponderance in ABR wave I amplitude; it was smaller in tinnitus ears of chronic tinnitus adolescents than in those of non-chronic tinnitus adolescents (p=0.114).

The probable site of origin of tinnitus in adolescents with normal hearing might be in the upper brainstem of the auditory pathway. Further analysis of ABR test results in adolescents with tinnitus and normal hearing can help clarify the pathophysiology of tinnitus in adolescents.

To establish an optimized airway management process to improve preoperative lung dysfunction in obstructive sleep apnea (OSA).

The study included 483 children (319 males and 164 females; 6y to14yyears) with OSA who underwent an adenotonsillectomy from November 2017 to December 2018. Children with OSA and who had abnormal airway function were identified by lung function test, and the risk factors for abnormal lung function were assessed. Next, the children received individualized atomization intervention based on the severity of their abnormal lung function, and the improvement in lung function was evaluated.

Lung function tests revealed that 45 patients had obstructive ventilation dysfunction, and histories of chronic cough or asthma were identified as risk factors for perioperative abnormal lung function. The FEV1% pre exceeded 80% after 2 days of atomization intervention in 27 of 28 mild cases, 4 of 13 moderate cases, but in none of the 4 moderate-severe cases. After 4 days of atomization intervention, the FEV1%pre of the remaining 14 patients in the three groups all increased up to 80%. Other indicators of lung function (e.g., FEV1/FVC% pre, MEF50% pre, MEF25% pre, and MMEF% pre) were also greatly improved following the improvement of FEV1% pre. No perioperative airway complications occurred.

Prior to performing surgery on children with OSA and who have risk factors associated with abnormal lung function, it is potentially beneficial to establish an optimized airway management process to improve lung function before adenotonsillectomy.

Multiple studies have shown improved outcomes and higher utilization of care with the increase of insurance coverage. This study aims to assess whether Medicaid expansion (ME) has changed the utilization and outcomes of abdominal aortic aneurysm (AAA) repair in the United States.

Retrospective observational study.

Data of patients undergoing AAA repair in the Vascular Quality Initiative (2010-2017).

Interrupted time-series (ITS) analysis was utilized to evaluate changes in annual trends of postoperative outcomes after elective AAA repair before and after 2014. We also assessed if these trend changes were significant by comparing the changes in states which adopted ME in 2014 versus nonexpansion states (NME), and conducting a difference-in-difference analysis. Primary outcomes included in-hospital mortality and adverse events (bowel and leg ischemia, cardiac, renal, respiratory, stroke and return to the OR).

A total of 19,143 procedures were included (Endovascular 85.8% and open 14.2%), of which 40.9s a significant increase of elective AAA cases and EVAR utilization and a decrease in in-hospital complications in ME States.The US National Park Service (NPS) Night Skies Program measured changes in sky brightness resulting from a countywide lighting retrofit project. The retrofit took place in Chelan County, a gateway community to North Cascades National Park and Lake Chelan National Recreation Area in Washington State. BI-3812 supplier The county retrofitted all 3693 county-owned high pressure sodium (HPS) street lamps to full cutoff LEDs. This number is about 60% of the County's total outdoor street and area lights. About 80% of the newly installed lights were 3000 K in color temperature and 20% were 4000 K. The 4000 K LEDs were used to meet Washington State Department of Transportation guidelines. To measure sky brightness, we used the NPS night sky camera system before the retrofit started in 2018 and after its completion in 2019. These images were photometrically calibrated and mosaicked together to provide hemispherical images in V band. For comparison with our ground-based measurement, we obtained the satellite imagery taken by Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Suomi National Polar-orbiting Partnership satellite.
