The labeling schema was coordinated with other international consensus panels and COVID-19 data annotation efforts, the European Society of Medical Imaging Informatics, the American College of Radiology, and the American Association of Physicists in Medicine. Study-level COVID-19 classification labels for chest radiographs were annotated by three radiologists, with majority vote adjudication by board-certified radiologists. RICORD consists of 240 thoracic CT scans and 1000 chest radiographs contributed from four international sites. It is anticipated that RICORD will ideally lead to prediction models that can demonstrate sustained performance across populations and health care systems.

To determine the difference in bleeding when extracapsular tonsillectomy with electrocautery is performed on the dominant and nondominant side of the surgeon’s hands.

Retrospective cohort study.

Academic university hospital.

Medical record data of patients who were admitted with posttonsillectomy bleeding from January 1, 2000, to July 31, 2017, were reviewed. Included were age, sex, surgical indication, side of posttonsillectomy bleeding, and time of bleeding. Information on the surgeon’s dominant hand was also collected. All patients underwent total extracapsular resection with electrocautery.

Of 280 patients, 186 met the inclusion criteria, 116 (62.3%) males and 70 (37.7%) females. Ages ranged from 2 to 74 years (mean ± SD, 17 ± 13 years; median, 13 years). In 136 cases (73.1%), bleeding was on the side of the surgeon’s nondominant hand (

< .0001). In 50 (26.9%) cases, bleeding was on the side of the surgeon’s dominant hand. The odds ratio of bleeding on the side of the surgeon’s nondominant hand compared to the dominant hand was 8.99.

The risk of bleeding following extracapsular tonsillectomy with electrocautery on the side of the surgeon’s nondominant hand is significantly higher than on the side of the dominant hand. Thus, additional caution is required when operating on the nondominant side of the oral cavity in extracapsular tonsillectomy using electrocautery. These findings raise questions regarding dexterity as a risk factor for posttonsillectomy bleeding.

From March 23 to June 20, 2020, in an online cross-sectional survey among 1380 US adults, we assessed physical symptoms, psychological symptoms, rumination, and perceived social support in order to describe differences between sexual and gender minority (n = 290) and cisgender heterosexual (n = 1090) respondents. Sexual and gender minority respondents had more frequent COVID-19-associated physical symptoms and depression and anxiety symptoms. Sexual and gender minorities had a significantly higher proportion of depression and anxiety scores exceeding the clinical concern threshold. Longitudinal studies on the physical and psychological impacts of COVID-19 among sexual and gender minority communities are needed to inform interventions to eliminate these disparities.

Outcome measures need to be valid and have good test-retest reliability and responsiveness. We compared the responsiveness of the RAND-12 and the Health Utilities Index-mark III (HUI3) in persons with multiple sclerosis (MS).

In Spring 2018 and 2019, North American Research Committee on Multiple Sclerosis (NARCOMS) registry participants completed the HUI3, the RAND-12, and reported disability (Patient Determined Disease Steps (PDDS)) and employment status (full-time, part-time, and no). We used changes in PDDS and employment status as anchors. We assessed responsiveness using effect size, standardized response mean, and the responsiveness index. We used relative efficiency (RE) to compare the responsiveness of the health-related quality of life (HRQOL) scores, adjusting for sociodemographic factors.

We included 4769 participants in the analysis. They had a mean (standard deviation (SD)) age of 60.9 (10.1) years, and 3826 participants (80.2%) were women. TWS119 molecular weight RE was highest for the HUI3 for changes in in disability status (HUI3 1.0, Physical Component Score-12 (PCS-12) 0.80, and Mental Component Score-12 (MCS-12) 0.41) and for changes in employment status (HUI3 1.0, PCS-12 0.70, and MCS-12 0.17).

The HUI3 was more responsive to changes in disability and employment status than the PCS-12 or MCS-12. Given the HUI3’s other strong psychometric properties, it may be the preferred generic measure of HRQOL in MS.

Insomnia and sleep apnea frequently co-occur, with additive effects of both disorders presenting clinicians with unique treatment challenges compared to one disorder alone. The hypoglossal nerve stimulator (HNS) is a promising treatment for patients with comorbid insomnia and sleep apnea (COMISA), many of whom have positive airway pressure (PAP) intolerance. Our aim was to determine adherence to and efficacy of HNS in veterans with COMISA refractory to PAP therapy compared to those with obstructive sleep apnea alone (OSA only).

Retrospective case series.

A single, academic Veterans Affairs medical center.

Review of clinical records, pre- and postoperative polysomnography, and clinical measures of obstructive sleep apnea (OSA), sleepiness, and insomnia was conducted in 53 consecutive cases of veterans with OSA undergoing HNS implantation. HNS adherence was obtained at postoperative visits. HNS adherence and efficacy were compared between individuals with COMISA and OSA only.

COMISA was noted in 30 of 53 (56.
