Background: Conditions of excess androgen in women, such as polycystic ovary syndrome (PCOS), often exhibit intergenerational transmission. One way in which the risk for PCOS may be increased in daughters of affected women is through exposure to elevated androgens in utero. Hyperandrogenemic conditions have serious health consequences, including increased risk for hypertension and cardiovascular disease. Recently, gut dysbiosis has been found to induce hypertension in rats, such that blood pressure can be normalized through fecal microbial transplant. Therefore, we hypothesized that the hypertension seen in PCOS has early origins in gut dysbiosis caused by in utero exposure to excess androgen. We investigated this hypothesis with a model of prenatal androgen (PNA) exposure and maternal hyperandrogenemia by single-injection of testosterone cypionate or sesame oil vehicle (VEH) to pregnant dams in late gestation. We then completed a gut microbiota and cardiometabolic profile of the adult female offspring. Results: The metabolic assessment revealed that adult PNA rats had increased body weight and increased mRNA expression of adipokines: adipocyte binding protein 2, adiponectin, and leptin in inguinal white adipose tissue. Radiotelemetry analysis revealed hypertension with decreased heart rate in PNA animals. The fecal microbiota profile of PNA animals contained higher relative abundance of bacteria associated with steroid hormone synthesis, Nocardiaceae and Clostridiaceae, and lower abundance of Akkermansia, Bacteroides, Lactobacillus, Clostridium. The PNA animals also had an increased relative abundance of bacteria associated with biosynthesis and elongation of unsaturated short chain fatty acids (SCFAs). Conclusions: We found that prenatal exposure to excess androgen negatively impacted cardiovascular function by increasing systolic and diastolic blood pressure and decreasing heart rate. Prenatal androgen was also associated with gut microbial dysbiosis and altered abundance of bacteria involved in metabolite production of short chain fatty acids. These results suggest that early-life exposure to hyperandrogenemia in daughters of women with PCOS may lead to long-term alterations in gut microbiota and cardiometabolic function.
Background The coronavirus disease 2019 (COVID-19) pandemic has demonstrated significantly worse outcomes for minority (black and Hispanic) individuals. Understanding the reasons for COVID-19–related disparities among patients with asthma has important public health implications. Objective To determine factors contributing to health disparities in those with asthma during the COVID-19 pandemic. Methods An anonymous survey was sent through social media to adult patients with asthma, and a separate survey was sent to physicians who provide asthma care. The patient survey addressed demographic information including socioeconomic status, asthma control, and attitudes/health behaviors during COVID-19. Results A total of 1171 patients (10.1% minority individuals) and 225 physicians completed the survey. Minority patients were more likely to have been affected by COVID-19 (eg, became unemployed, lived in a community with high COVID-19 cases). They had worse asthma control (increased emergency visits for asthma, lower Asthma Control Test score), were more likely to live in urban areas, and had a lower household income. Initial differences in attitudes and health behaviors disappeared after controlling for baseline demographic features. Institutional racism was demonstrated by findings that minority individuals were less likely to have a primary care physician, had more trouble affording asthma medications due to COVID-19, and were more likely to have lost health insurance because of COVID-19, and that 25% of physicians found it more challenging to care for black individuals with asthma during COVID-19. Conclusions Differences in socioeconomic status and the effects of institutional racism, but not health behaviors, sources of information, or attitudes, are playing a role in disparities seen for patients with asthma during COVID-19.
OBJECTIVE: The aim of this study was to explore differences in attitudes, behaviors and expectations related to COVID-19 between physicians and patients with asthma. METHODS: An anonymous survey was distributed through email and social media to adult patients with asthma during a three-week period in April-May 2020. A separate survey was sent to physicians. The surveys asked about demographic information, specific challenges and concerns due to COVID-19, and attitudes/behaviors during this time. RESULTS: A total of 1171 patients and 225 physicians completed the surveys. Overall, patients with asthma and physicians had large differences in expectations related to COVID-19. Patients were more likely than physicians to believe that individuals with asthma are at a higher risk to get COVID-19 (37.5% vs. 12.0%, p < 0.001), have increased anxiety due to COVID-19 (79.6% vs 70.0%, p = 0.002), and should not go to work (62.7% vs 11.9%, p < 0.001). Neither patients nor physicians felt confident they could distinguish COVID-19 symptoms from asthma (61.2% and 74.5% did not feel confident, respectively). Patients with severe asthma were significantly more impacted by the pandemic (e.g. became unemployed [OR 2.15], had difficulty getting asthma meds [OR 2.37]) compared to those with nonsevere asthma. CONCLUSION: Patients with asthma and their physicians have markedly different attitudes and opinions regarding care during the COVID-19 pandemic. Such differences have important implications when providing patient-centered care.
