Adaptations in orthodontics for current and future coronavirus disease 2019 best practices.

INTRODUCTION: This study aimed to determine adaptations orthodontists made during the coronavirus disease 2019 pandemic to maintain safety and determine which adaptations will remain after the pandemic. METHODS: An original 34-question survey was sent by mail to a randomized selection of practicing orthodontic specialists (n = 1000). Questions included the changes made during the pandemic in 4 categories (infection control, social distancing, appliance type, and teleorthodontics) and whether those changes will remain postpandemic. RESULTS: The use of personal protective equipment increased during the pandemic, with a significant decrease anticipated after the pandemic. The most common aerosol modification during the pandemic and predicted after the pandemic was using an assistant with high-volume suction (61% and 49%, respectively; P = 0.0013). Ninety-six percent of orthodontists changed their waiting room protocol during the pandemic, but only 23% plan to continue that practice (P <0.0001). Forty-two percent of orthodontists increased clear aligners during the pandemic in response to patient demand (91%). The use of teleorthodontics increased from 8% to 68% during the pandemic and is expected to decrease significantly postpandemic. Virtual appointments are anticipated to be used for screening and consultations of new patients and monitoring active patients in clear aligners but not fixed appliances. CONCLUSIONS: The specialty recommended patient safety modifications during the coronavirus disease 2019 pandemic. Postpandemic, enhanced personal protective equipment is expected to decrease, and high-volume suction will likely be continued for aerosol-producing procedures. Teleorthodontics will likely remain in limited use.

Assessment of Racial Disparities in Aspirin Prophylaxis for Preeclampsia Prevention.

OBJECTIVE: Low-dose aspirin is recommended for preeclampsia prevention among women with high-risk conditions, including chronic hypertension. Black women have higher rates of hypertensive disorders of pregnancy, and whether this is related to disparities in aspirin prophylaxis is unknown. We investigated the relationship between race and counseling/prescription and uptake of aspirin among a cohort of women with chronic hypertension. STUDY DESIGN: This is a single-institution, retrospective cohort study of women with chronic hypertension who delivered between 2016 and 2018. Medical record review was performed to assess counseling/prescription of aspirin prophylaxis and self-reported uptake. Self-reported uptake was determined by mention in the provider's notes or by inclusion in the medication reconciliation system. Demographic and obstetric outcome data were compared by self-reported race (Black vs. all other races) in univariate analysis. Multivariable logistic regression analysis was performed to evaluate the association between race and aspirin adherence. RESULTS: We included 872 women: 361 (41.4%) Black women and 511 (58.6%) white or other race women. Overall, 567 (65.0%) women were counseled and/or given a prescription for aspirin, and 411 (72.4%) of those women reported uptake. Black women were equally likely to be counseled and/or prescribed aspirin compared with all other races (67.3 vs. 63.4%; p = 0.7). However, Black women were less likely to report uptake of aspirin (63.8 vs. 79.0%; p < 0.001). After adjustment for total prenatal visits and tobacco use, Black race was associated with an adjusted odds ratio of 0.53 (95% confidence interval: 0.36-0.78) for uptake of aspirin. CONCLUSION: In our cohort, recommendation for aspirin prophylaxis was suboptimal in all groups, reaching only 65% of eligible women. Black women were equally likely as women of other races to receive counseling about aspirin, but rates of uptake were lower. Our findings suggest that counseling and prescription of aspirin alone in high-risk Black women are not sufficient for utilization of this intervention. KEY POINTS: · Rates of counseling about aspirin prophylaxis for preeclampsia did not vary by race.. · Black women had lower rates of uptake of aspirin compared with women of other races.. · Counseling about aspirin was inadequate in general, reaching only 65% of eligible women..

Visual Learning Equity: A Course Auditing System of Skin Color in Preclinical Medical Education.

BACKGROUND AND OBJECTIVES: Visual learning equity is a health justice effort in response to the lack of representation of brown and black skin images in medical education. This paucity creates a knowledge gap and decreases providers' competence in managing skin disease in minoritized populations. Herein, we aimed to create a standardized course auditing system to assess the use of brown and black skin images in medical education. METHODS: We performed a cross-sectional analysis of the 2020-2021 preclinical curriculum at one US medical school. All human images in the learning material were analyzed. Skin color was categorized as light/white, medium/brown, and dark/black using the Massey-Martin New Immigrant Survey Skin Color Scale. RESULTS: We included 1,660 unique images in our analysis; 71.3%, (n=1,183) were light/white, 16.1% (n=267) were medium/brown and 12.7% (n=210) were dark/black. Dermatologic images of skin, hair, nails, or mucosal disease made up 62.1% (n=1,031) of the images and 68.1% (n=702) were light/white. The pulmonary course presented the highest proportion of light/white skin (88.0%, n=44/50) and the dermatology course presented the lowest proportion of light/white skin (59.0%, n=301/510). Images of infectious diseases were more frequently presented in darker skin colors (χ2 [2]=15.46, P<.001). CONCLUSIONS: Light/white skin was the standard used for visual learning images in the medical school curriculum at this institution. The authors outline steps to perform a curriculum audit and diversify medical curricula to ensure the next generation of physicians are educated to care for all patients.

Patient Factors Associated With Teledermatology Visit Type and Submission of Photographs During the COVID-19 Pandemic: Cross-sectional Analysis.

BACKGROUND: The COVID-19 pandemic necessitated the widespread adoption of teledermatology, and this continues to account for a significant proportion of dermatology visits after clinics have reopened for in-person care. Delivery of high-quality teledermatology care requires adequate visualization of the patient's skin, with photographs being preferred over live video for remote skin examination. It remains unknown which patients face the greatest barriers to participating in a teledermatology visit with photographs. OBJECTIVE: The aim of this study was to identify patient characteristics associated with type of telemedicine visit and the factors associated with participating in teledermatology visits with digital photographs versus those without photographs. METHODS: We performed a cross-sectional analysis of the University of Pennsylvania Health System electronic health record data for adult patients who participated in at least 1 teledermatology appointment between March 1, 2020, and June 30, 2020. The primary outcomes were participation in a live-interactive video visit versus a telephone visit and participation in any teledermatology visit with photographs versus one without photographs. Multivariable logistic regression was performed to evaluate the associations between patient characteristics and the primary outcomes. RESULTS: In total, 5717 unique patients completed at least 1 teledermatology visit during the study period; 68.25% (n=3902) of patients participated in a video visit, and 31.75% (n=1815) participated in a telephone visit. A minority of patients (n=1815, 31.75%) submitted photographs for their video or telephone appointment. Patients who submitted photographs for their teledermatology visit were more likely to be White, have commercial insurance, and live in areas with higher income, better education, and greater access to a computer and high-speed internet (P<.001 for all). In adjusted analysis, older age (age group >75 years: odds ratio [OR] 0.60, 95% CI 0.44-0.82), male sex (OR 0.85, 95% CI 0.75-0.97), Black race (OR 0.79, 95% CI 0.65-0.96), and Medicaid insurance (OR 0.81, 95% CI 0.66-0.99) were each associated with lower odds of a patient submitting photographs for their video or telephone visit. Older age (age group >75 years: OR 0.37, 95% CI 0.27-0.50) and Black race (OR 0.82, 95% CI 0.68-0.98) were also associated with lower odds of a patient participating in a video visit versus telephone visit. CONCLUSIONS: Patients who were older, male, or Black, or who had Medicaid insurance were less likely to participate in teledermatology visits with photographs and may be particularly vulnerable to disparities in teledermatology care. Further research is necessary to identify the barriers to patients providing photographs for remote dermatology visits and to develop targeted interventions to facilitate equitable participation in teledermatology care.

Interleukin 1ß inhibition contributes to the antinociceptive effects of voluntary exercise on ischemia/reperfusion-induced hypersensitivity.

Issues of peripheral circulation have been increasingly suggested as an underlying cause of musculoskeletal pain in many conditions, including sickle cell anemia and peripheral vascular disease. We have previously shown in our model of transient ischemia and reperfusion (I/R) injury of the forelimb that individual group III and IV muscle afferents display altered chemosensitivity and mechanical thresholds 1 day after injury. Functional alterations corresponded to increased evoked and spontaneous pain-related behaviors and decreased muscle strength and voluntary activity-all actions that echo clinical symptoms of ischemic myalgia. These behavioral and physiological changes appeared to originate in part from the action of increased interleukin 1ß (IL1ß) in the injured muscles at its upregulated IL1 receptor 1 within the dorsal root ganglion. Here, we describe that two days of voluntary wheel running prior to I/R blocks both injury-induced IL1ß enhancement and the subsequent development of ischemic myalgia-like behaviors. Furthermore, the protective effects of 2 days prior exercise on the I/R-evoked increases in pain-related behaviors were also paralleled with systemic injection of the IL1 receptor antagonist during I/R. Interleukin 1 receptor antagonist treatment additionally prevented the I/R-induced changes in mechanical and chemical sensitivity of individual primary muscle afferents. Altogether, these data strengthen the evidence that transient I/R injury sensitizes group III and IV muscle afferents via increased IL1ß in the muscles to stimulate ischemic myalgia development. Targeting IL1ß may, therefore, be an effective treatment strategy for this insidious type of muscle pain.

Sex differences in primary muscle afferent sensitization following ischemia and reperfusion injury.

BACKGROUND: Chronic pain conditions are more prevalent in women, but most preclinical studies into mechanisms of pain generation are performed using male animals. Furthermore, whereas group III and IV nociceptive muscle afferents provoke central sensitization more effectively than their cutaneous counterparts, less is known about this critical population of muscle nociceptors. Here, we compare the physiology of individual muscle afferents in uninjured males and females. We then characterize the molecular, physiological, and behavioral effects of transient ischemia and reperfusion injury (I/R), a model we have extensively studied in males and in females. METHODS: Response properties and phenotypes to mechanical, thermal, and chemical stimulation were compared using an ex vivo muscle/nerve/dorsal root ganglia (DRG)/spinal cord recording preparation. Analyses of injury-related changes were also performed by assaying evoked and spontaneous pain-related behaviors, as well as mRNA expression of the affected muscle and DRGs. The appropriate analyses of variance and post hoc tests (with false discovery rate corrections when needed) were performed for each measure. RESULTS: Females have more mechanically sensitive muscle afferents and show greater mechanical and thermal responsiveness than what is found in males. With I/R, both sexes show fewer cells responsive to an innocuous metabolite solution (ATP, lactic acid, and protons), and lower mechanical thresholds in individual afferents; however, females also possess altered thermal responsiveness, which may be related to sex-dependent changes in gene expression within the affected DRGs. Regardless, both sexes show similar increases in I/R-induced pain-like behaviors. CONCLUSIONS: Here, we illustrate a unique phenomenon wherein discrete, sex-dependent mechanisms of primary muscle afferent sensitization after ischemic injury to the periphery may underlie similar behavioral changes between the sexes. Furthermore, although the group III and IV muscle afferents are fully developed functionally, the differential mechanisms of sensitization manifest prior to sexual maturity. Hence, this study illustrates the pressing need for further exploration of sex differences in afferent function throughout the lifespan for use in developing appropriately targeted pain therapies.
