ABSTRACT
BACKGROUND: People with kidney failure treated with dialysis are at increased risk of SARS-CoV-2 infection, and severe COVID-19 outcomes such as hospitalization and death. Though there are well-defined sex differences in outcomes for the general population with COVID-19, we do not know whether this translates into kidney failure populations. We aimed to estimate the differences in COVID-19 symptoms and clinical outcomes between males and females treated with maintenance dialysis. METHODS: In this prospective observational cohort study, we included adults treated with maintenance dialysis in Southern Alberta, Canada that tested positive for COVID-19 between March 2020 and February 2022. We examined the association between sex (dichotomized as male and female) with COVID-19 symptoms including fever, cough, malaise, shortness of breath, muscle joints/aches, nausea and/or vomiting, loss of appetite, diarrhea, headache, sore throat, and loss of smell/taste using chi-square or Fisher's exact tests. Secondary outcomes included 30-day hospitalization, ICU admission, and death. RESULTS: Of 1,329 cohort participants, 246 (18.5%) tested positive for SARS-CoV-2 and were included in our study, including 95 females (39%). Of 207 participants with symptoms assessed, females had less frequent fever (p = 0.003), and more nausea or vomiting (p = 0.003) compared to males, after correction for multiple testing. Males exhibited no symptoms 25% of the time, compared with 10% of females (p = 0.01, not significant when corrected for multiple testing). We did not identify statistically significant differences in clinical outcomes between the sexes, though vaccinated patients had lower odds of hospitalization. CONCLUSIONS: Sex differences in COVID-19 symptoms were identified in a cohort of patients treated with maintenance dialysis, which may inform sex-specific screening strategies in dialysis units. Further work is necessary to examine mechanisms for identified sex differences.
ABSTRACT
BACKGROUND: Pre-existing gender-based disparities in academia may have worsened during the COVID-19 pandemic. Being cited as an expert source in newspaper articles about COVID-19 may increase an individual's research or leadership profile. In addition, visibility in a newspaper article is an important component of representation in academia. OBJECTIVE: To determine whether women were underrepresented as COVID-19 expert sources in print newspapers in the USA. DESIGN: We undertook a cross-sectional study of English-language newspaper articles that addressed the COVID-19 pandemic and that were published in the top 10 most widely read newspapers in the USA between April 1 and April 15, 2020. MAIN MEASURES: We extracted the names of all people cited as expert sources and categorized the gender of each expert source based on pronoun usage within the article or on a business, university, or organization website. The professional role of each expert was assigned based on their description in the article. KEY RESULTS: Of 2297 expert sources identified, 35.9% (95% confidence interval [CI] 33.9-37.8%; n = 824) were women and 63.7% were men (95% CI 61.8-65.7%; n = 1464). This result was similar when considering unique experts in each newspaper and for all included newspapers; of the 1738 unique experts per newspaper, 34.6% were women (95% CI 32.3-36.8%; n = 601), and of the 1593 unique experts in all newspapers, 36.5% were women (95% CI 34.1-38.9%; n = 581). Of articles with multiple experts referenced (n = 374), 102 cited only men experts (27.3%) and 44 cited only women experts (11.8%). Women were underrepresented as experts as Healthcare Workers and Professionals, Non-STEM Experts, Public Health Leaders, and STEM Scientists. There were no differences in the proportion of women experts between newspapers or between different regions of the USA. CONCLUSIONS: Altogether, our findings support that men academics outnumber women as COVID-19 experts in newspaper articles.
