RESUMEN
BACKGROUND: Black women bear a disproportionate burden of cardiovascular diseases, potentially due to altered central hemodynamics. Racism and sexism often lead to Black women taking on numerous caretaking roles and overall increases their use of the Strong Black Woman (ie, Superwoman) mindset, which may have negative health consequences. We hypothesized that endorsing the Superwoman role and its Obligation to Help Others dimension would be associated with a deleterious central hemodynamics profile in Black women. METHODS AND RESULTS: Using cross-sectional data, we examined central systolic blood pressure (mm Hg; n=408), augmentation index (percentage, adjusted for height and heart rate; n=408), and pulse wave velocity (m/s; n=368) in Black women aged 30 to 46 years. The Giscombe Superwoman Schema (SWS) questionnaire assessed endorsement of Overall SWS (range, 0-105) and SWS-Obligation to Help Others (range, 0-3). Multiple linear regression modeled associations between Overall SWS (10-unit increments) and SWS-Obligation to Help Others (1-unit increments) and central hemodynamics while adjusting for pertinent sociodemographic, clinical, and psychosocial factors. In fully adjusted models, central systolic blood pressure was significantly associated with Overall SWS (ß=0.83 [95% CI, 0.19-1.47]) and SWS-Obligation to Help Others (ß=2.03 [95% CI, 0.39-3.67]). Augmentation index was associated with Overall SWS (ß=0.66 [95% CI, 0.02-1.30]) and SWS-Obligation to Help Others (ß=2.21 [95% CI, 0.58-3.84]). Significant associations were not observed between pulse wave velocity and SWS. CONCLUSIONS: Greater endorsement of the Superwoman role and prioritizing caregiving over self-care were associated with higher central systolic blood pressure and augmentation index, which may contribute to adverse cardiovascular health among Black women.
RESUMEN
Limited data highlight the need to understand differences in SARS-CoV-2 omicron (B.1.1.529) variant viral load between the gold standard nasopharyngeal (NP) swab, mid-turbinate (MT)/anterior nasal swabs, oropharyngeal (OP) swabs, and saliva. MT, OP, and saliva samples from symptomatic individuals in Atlanta, GA, in January 2022 and longitudinal samples from a small familial cohort were tested by both RT-PCR and ultrasensitive antigen assays. Higher concentrations in the nares were observed in the familial cohort, but a dominant sample type was not found among 39 cases in the cross-sectional cohort. The composite of positive MT or OP assay for both RT-PCR and antigen assay trended toward higher diagnostic yield but did not achieve significant difference. Our data did not identify a singular preferred sample type for SARS-CoV-2 testing, but higher levels of saliva nucleocapsid, a trend toward higher yield of composite OP/MT result, and association of apparent MT or OP predominance with symptoms warrant further study.
RESUMEN
OBJECTIVES: Similar to women overall, Black women are socialized to be communal and "self-sacrificing," but unlike women from other racial/ethnic backgrounds, Black women are also socialized to be "strong" and "invulnerable." This phenomenon is labeled Superwoman schema. This study examined associations between Superwoman schema endorsement and subjective sleep quality. METHODS: Participants included 405 Black women (ages 30-46). Superwoman schema was measured using a 35-item scale capturing five dimensions: obligation to present strength, suppress emotions, resistance to vulnerability, motivation to succeed, and obligation to help others. Superwoman schema overall and the five dimensions/subscales were analyzed. The Pittsburgh Sleep Quality Index (PSQI) was used to investigate overall subjective sleep quality (range: 0-19), poor sleep quality (PSQI >5), and specific sleep domains (eg, sleep duration, sleep disturbances). We fit linear and binary logistic regression models, adjusting for health-related and sociodemographic factors. RESULTS: Superwoman schema dimension obligation to help others was associated with lower overall subjective sleep quality (ß: .81, 95%CI=0.29, 1.32) and poor sleep quality (OR: 1.55, 95%CI=1.10, 2.19), as well as bad subjective sleep quality (OR: 1.76, 95%CI=1.18, 2.66), sleep disturbances (ß: .73, 95%CI =0.07, 1.41), and daytime sleepiness (OR: 2.01, 95%CI=1.25, 3.26). Suppress emotions (OR: 1.41, 95%CI=1.01, 1.99) was associated with poor subjective sleep quality. Superwoman schema overall was associated with daytime sleepiness (OR: 2.01, 95%CI=1.06, 3.82). CONCLUSION: Superwoman schema endorsement, especially obligation to help others and suppress emotions, may be important psychosocial risk factors for Black women's sleep health.

BACKGROUND: Upper respiratory samples for SARS-CoV-2 detection include the gold standard nasopharyngeal (NP) swab, and mid-turbinate (MT) nasal swabs, oropharyngeal (OP) swabs, and saliva. Following the emergence of the omicron (B.1.1.529) variant, limited preliminary data suggest that OP swabs or saliva samples may be more sensitive than nasal swabs, highlighting the need to understand differences in viral load across different sites. METHODS: MT, OP, and saliva samples were collected from symptomatic individuals presenting for evaluation in Atlanta, GA, in January 2022. Longitudinal samples were collected from a family cohort following COVID-19 exposure to describe detection of viral targets over the course of infection. RESULTS: SARS-CoV-2 RNA and nucleocapsid antigen measurements demonstrated a nares-predominant phenotype in a familial cohort. A consistent dominant location for SARS-CoV-2 was not found among 54 individuals. Positive percent agreement for virus detection in MT, OP and saliva specimens were 66.7 [54.1-79.2], 82.2 [71.1-93.4], and 72.5 [60.3-84.8] by RT-PCR, respectively, and 46.2 [32.6-59.7], 51.2 [36.2-66.1], and 72.0 [59.6-84.4] by ultrasensitive antigen assay. The composite of positive MT or OP assay was not significantly different than either alone for both RT-PCR and antigen assay (PPA 86.7 [76.7-96.6] and 59.5 [44.7-74.4], respectively). CONCLUSIONS: Our data suggest that SARS-CoV-2 nucleocapsid and RNA exhibited similar kinetics and diagnostic yield in three upper respiratory sample types across the duration of symptomatic disease. Collection of OP or combined nasal and OP samples does not appear to increase sensitivity versus validated nasal sampling for rapid detection of viral antigen.
RESUMEN
BACKGROUND AND PURPOSE: Medical and endovascular treatment options for stroke prevention in patients with symptomatic intracranial stenosis have evolved over the past several decades, but the impact of 2 major multicenter randomized stroke prevention trials on physician practices has not been studied. We sought to determine changes in US physician treatment choices for patients with intracranial atherosclerotic stenosis (ICAS) following 2 NIH-funded clinical trials that studied medical therapies (antithrombotic agents and risk factor control) and percutaneous transluminal angioplasty and stenting (PTAS). METHODS: Anonymous surveys on treatment practices in patients with ICAS were sent to physicians at 3 time points: before publication of the NIH-funded Warfarin-Aspirin Symptomatic Intracranial Disease (WASID) trial (pre-WASID survey, 2004), 1 year after WASID publication (post-WASID survey, 2006) and 1 year after the publication of the NIH-funded Stenting and Aggressive Medical Management for Preventing Recurrent Stroke in Intracranial Stenosis (SAMMPRIS) trial (post-SAMMPRIS survey, 2012). Neurologists were invited to participate in the pre-WASID survey (n=525). Neurologists and neurointerventionists were invited to participate in the post-WASID (n=598) and post-SAMMPRIS (n=2,080) surveys. The 3 surveys were conducted using web-based survey tools delivered by E-mail, and a fax-based response form delivered by E-mail and conventional mail. Data were analyzed using the χ2 test. RESULTS: Before WASID, there was equipoise between warfarin and aspirin for stroke prevention in patients with ICAS. The number of respondents who recommended antiplatelet treatment for ICAS increased across all 3 surveys for both anterior circulation (pre-WASID=44%, post-WASID=85%, post-SAMMPRIS=94%) and posterior circulation (pre-WASID=36%, post-WASID=74%, post-SAMMPRIS=83%). The antiplatelet agent most commonly recommended after WASID was aspirin, but after SAMMPRIS it was the combination of aspirin and clopidogrel. The percentage of neurologists who recommended PTAS in >25% of ICAS patients increased slightly from pre-WASID (8%) to post-WASID surveys (12%), but then decreased again after SAMMPRIS (6%). The percentage of neurointerventionists who recommended PTAS in >25% of ICAS patients decreased from post-WASID (49%) to post-SAMMPRIS surveys (17%). CONCLUSIONS: The surveyed US physicians' recommended treatments for ICAS differed over the 3 survey periods, reflecting the results of the 2 NIH-funded clinical trials of ICAS and suggesting that these clinical trials changed practice in the USA.

BACKGROUND: Acute isolated optic neuritis is often the first manifestation of multiple sclerosis (MS), and its management remains controversial. Over the past decade, with the advent of new disease-modifying agents, management of isolated optic neuritis has become more complicated. OBJECTIVES: To evaluate the current practice patterns of Canadian ophthalmologists and neurologists in the management of acute optic neuritis, and to evaluate the impact of recently published randomized clinical trials. DESIGN: Mail survey. METHODS: All practicing ophthalmologists and neurologists in Canada were mailed a survey evaluating the management of isolated acute optic neuritis and familiarity with recent clinical trials. Surveys for 1158 were mailed, and completed surveys were collected anonymously through a datafax system. Second and third mailings were sent to non-respondents 6 and 12 weeks later. RESULTS: The final response rate was 34.5%. Although many acute optic neuritis patients initially present to ophthalmologists, neurologists are the physicians primarily managing these patients. Ordering magnetic resonance imaging, and treating with high dose intravenous steroids has become the standard of care. However, 15% of physicians (14% of ophthalmologists and 16% of neurologists) continue to prescribe low dose oral steroids, and steroids are being given for reasons other than to shorten the duration of visual symptoms by 73% of ophthalmologists and 50% of neurologists. More neurologists than ophthalmologists are familiar with recent clinical trials involving disease-modifying agents. CONCLUSION: Although the management of acute optic neuritis has been evaluated in large clinical trials that were published in major international journals, some ophthalmologists and neurologists are not following evidence-based recommendations.
