    Abstract: Background The clinical phenotype and complications of sickle cell disease (SCD) are heterogeneous and disease outcomes are influenced by both genetic and non-genetic factors, including geography, socioeconomic and educational status and access to health care. These factors serve a role in the quality of life and overall survival in the SCD population. Prior studies have sought to characterize the genotype-phenotype relationship and geographic clustering of SCD with distinct clinical differences found between the African and Asian SCD subtypes. The Central Missouri SCD Cohort (MU-SCD Cohort) has a heterogeneous population of SCD patients who seek medical care from University of Missouri. The clinical characteristics and frequency of SCD-related complications in this group have not yet been defined. This is a retrospective cohort analysis of patients HbSS, HbSC, and HbS/b-thalassemia in central Missouri, ranging in age from the first through the sixth decade of life. We hypothesize that SCD patients from central Missouri, with its mix of African American, Congolese, Nigerian, Kenyan, Southeast Asian and other refugee populations, will have clinical complications distinct from the previously described North American Sickle Cell Disease series and needs further characterization. Objective To survey the SCD phenotype by evaluating complications of patients in the MU-Sickle Cell Disease Cohort. Methods We retrospectively reviewed clinical and laboratory data for pediatric and adult SCD patients who were treated at the University of Missouri between 2002 to 2018. Prevalence of major vaso-occlusive, hemolytic and renal complications by decade was estimated. Results A total of 81 patients were reviewed, with five excluded due to insufficient clinical data. The sample size for prevalence estimation was 76, 61, 30, 14 and 8 for first to fifth decade, respectively. In this cohort, 60.5% were male with average age of 21.2 years. Genotypes represented included 52.6% HbSS, 38.2% HbSC, and 7.9% HbS/b-thalassemia. A total of 94.7% of patients identified as African American. Clinical features of vaso-occlusive complications predominated in the first two decades of life. The frequency of acute chest syndrome for patients ages ≤10 years and 11-20 years of age were 23.7% and 21.3%, respectively (Table 1). Seven children (9.2%) developed overt stroke by age 10 years. Greater than one vaso-occlusive pain crisis occurred in 46% of patients in the first decade of life and thereafter declined with age (Figure 1). In contrast, the MU-SCD Cohort exhibited increasing frequency of hemolytic complications with advancing age. The peak prevalence of pulmonary hypertension occurred between the ages of 21-30 years (13.3%). In congruence, only 4% of patients aged ≤10 years were diagnosed with gallstones requiring cholecystectomy, which increased to 57.1% at age 31-40 years. Reticulocytopenia was noted in the fourth decade with further decline in the fifth decade of life (Figure 2). Renal evaluation revealed an average estimated glomerular filtration rate (eGFR) of 149.9 ± 43 in patients ≤10 years, with progressive decline to 117.3 ± 25 in SCD patients aged 41-50 years (Figure 3). The average serum creatinine demonstrated an increasing trend with advancing age. There was a prevalence of persistent proteinuria in patients older than 11 years. Disease modifying agents were assessed, in which only 21% of patients ≤10 years, 25% of patients aged 11-20 years, and 15.8% of patients aged 21-30 years received therapy with hydroxyurea (Table 1). The use of exchange transfusion or packed red blood cell (pRBC) transfusion for anemia was predominant in SCD patients aged ≤20 years. Conclusions This is the first report describing prevalence of SCD-related complications in the MU-SCD Cohort. We identified this population to have an increasing frequency of hemolytic complications and sickle cell nephropathy with advancing age. Onset of persistent proteinuria occurred in the second decade of life, followed by renal insufficiency or end stage renal disease in subsequent decades. As previously demonstrated in the Cooperative Study of Sickle Cell Disease and the Jamaican SCD Cohort study, renal insufficiency was a significant risk factor for early mortality. Further studies are required for identification of biomarkers and institution of early intervention strategies to prevent end-organ damage and decrease mortality in SCD.

    Abstract: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection produces more severe symptoms and a higher mortality in men than in women. The role of biological sex in the immune response to SARS-CoV-2 is believed to explain this sex disparity. However, the contribution of gender factors that influence health protective behaviors and therefore health outcomes, remains poorly explored. Methods We assessed the contributions of gender in attitudes towards the COVID-19 pandemic, using a hypothetical influenza pandemic data from the 2019 Taiwan Social Change Survey. Participants were selected through a stratified, three-stage probability proportional-to-size sampling from across the nation, to fill in questionnaires that asked about their perception of the hypothetical pandemic, and intention to adopt health protective behaviors. Results A total of 1,990 participants (median age = 45·92 years, 49% were women) were included. Significant gender disparities (p  〈  .001) were observed. The risk perception of pandemic (OR = 1·28, 95% CI [1·21 − 1·35], p  〈  .001), older age (OR = 1·06, 95% CI [1·05 − 1·07], p  〈  .001), female gender (OR = 1·18, 95% CI [1·09-1·27], p  〈  .001), higher education (OR = 1·10, 95% CI [1·06 − 1·13], p  〈  .001), and larger family size (OR = 1·09, 95% CI [1·06 − 1·15], p  〈  .001) were positively associated with health protective behaviors. The risk perception of pandemic (OR = 1·25, 95% CI [1·15 − 1·36]), higher education (OR = 1·07, 95% CI [1·02 − 1·13] , p  〈  .05), being married (OR = 1·17, 95% CI [1·01–1·36, p  〈  .05), and larger family size (OR = 1·33, 95% CI [1·25 − 1·42], p  〈  .001), were positively associated with intention to receive a vaccine. However, female gender was negatively associated with intention to receive a vaccine (OR = 0·85, 95% CI [0·75 − 0·90], p 〈 ·01) and to comply with contact-tracing (OR = 0·95, 95% CI [0·90 − 1·00], p  〈  .05) compared to men. Living with children was also negatively associated with intention to receive vaccines (OR = 0·77, 95% CI [0·66 − 0·90], p  〈  .001). Conclusion This study unveils gender differences in risk perception, health protective behaviors, vaccine hesitancy, and compliance with contact-tracing using a hypothetical viral pandemic. Gender-specific health education raising awareness of health protective behaviors may be beneficial to prevent future pandemics.

    Abstract: The impact of comorbidities and biomarkers on COVID-19 severity vary by sex but have not yet been verified in population-based studies. We examined the association of comorbidities, inflammatory biomarkers, and severe outcomes in men and women hospitalized for COVID-19. Design This is a retrospective cohort analysis based on the National COVID Cohort Collaborative (N3C). We included 574,391 adult patients admitted for COVID-19 at hospitals or emergency rooms between 01/01/2020 and 12/31/2021. Methods We defined comorbidities at or before the first admission for COVID-19 by Charlson Comorbidity Index (CCI) and CCI components. We used the averaged lab values taken within 15 days before or after the admission date to measure biomarkers including c-reactive protein (CRP), ferritin, procalcitonin, N-terminal pro b-type natriuretic peptide (NT proBNP), d-dimer, absolute lymphocyte counts, absolute neutrophil counts, and platelets. Our primary outcome was all-cause mortality; secondary outcomes were invasive mechanical ventilation (IMV) and hospital length of stay (LOS). We used logistic regression adjusted for age, race, ethnicity, visit type, and medications to assess the association of comorbidities, biomarkers, and mortality disaggregating by sex. Results Moderate to severe liver disease, renal disease, metastatic solid tumor, and myocardial infarction were the top four fatal comorbidities among patients who were hospitalized for COVID-19 (adjusted odds ratio [aOR]  〉  2). These four comorbid conditions remained the most lethal in both sexes, with a higher magnitude of risk in women than in men (p-interaction  〈  0.05). Abnormal elevations of CRP, ferritin, procalcitonin, NT proBNP, neutrophil, and platelet counts, and lymphocytopenia were significantly associated with the risk of death, with procalcitonin and NT proBNP as the strongest predictors (aOR  〉  2). The association between the abnormal biomarkers and death was stronger in women than in men (p-interaction  〈  0.05). Conclusion There are sex differences in inpatient mortality associated with comorbidities and biomarkers. The significant impact of these clinical determinants in women with COVID-19 may be underappreciated as previous studies stressed the increased death rate in male patients that is related to comorbidities or inflammation. Our study highlights the importance and the need for sex-disaggregated research to understand the risk factors of poor outcomes and health disparities in COVID-19.

    Abstract: Background: Diabetes (DM) diminishes female protection against cardiovascular disease (CVD). Women with DM face excess CVD risk than men partly due to women’s greater deterioration in risk factors before DM. In this study, we compared sex differences in biomarkers that reflect distinct pathophysiological pathways during the pre-diabetes (pre-DM) stage. Method: A cross-sectional analysis was performed based on pooled data from Atherosclerosis Risk in Communities Study and the Jackson Heart Study. We used multivariable linear regressions to examine the associations between sex and biomarkers (log-transformed) representative of inflammation, lipoprotein, adipokine, kidney function, cardiac injury/stress, and thrombosis, adjusted for age, race, and BMI, among CVD-free individuals with pre-DM. We validated the results in a sensitivity analysis, including those that eventually progressed into DM during the follow-up. We used the false discovery rate method to adjust multiple comparisons. Results: Among 5975 individuals with pre-DM, the mean age was 54.2 years, 2853 (48%) were women, and 2022 (34%) were non-Hispanic blacks. In the adjusted models, inflammatory biomarkers, including high-sensitivity c-reactive proteins (β coefficient 0.2, P=2.9 x 10 -9 ), fibrinogen (β 0.19, P=2.8E-12), and absolute lymphocyte (β 0.25, P=2.54 x 10 -7 ), and cardiac injury/stress biomarker, NT-proBNT (β 0.14, P=0.0002) were higher in women than men with pre-DM. Additionally, lipoprotein(a) (β 0.19, P=4.96 x 10 -13 ) and apolipoproteins A1 (β 0.61, P=2.81x 10 -120 ), and adipokines including leptin (β 1.1, P=2.62 x 10 -123 ) and adiponectin (β 0.56, P=1.94 x 10 -12 ) were all higher in women with pre-DM. In contrast, kidney function markers, albumin (β -0.24, P=2.79 x 10 -9 ) and creatinine (β -1.1, P=1x 10 -100 ), and thrombosis biomarker, homocysteine (β -0.5, P=9.09 x 10 -19 ) were higher in men with pre-DM than in their women counterparts. These sex differences remained generally unchanged among 2320 individuals that progressed into DM. Conclusion: Biomarkers differ significantly between sexes during the pre-DM state. The inflammatory, lipoprotein, adipokine, and cardiac stress biomarkers were higher in women with pre-DM, while kidney function and thrombosis biomarkers were higher in men with pre-DM. Future mechanistic studies are warranted to delineate pathophysiological pathways characterized by these biomarkers contributing to sex disparities of CVD risk in DM.

    Abstract: Objective: Women with type 2 diabetes (T2DM) have a 25-50% higher risk of cardiovascular disease (CVD) than their men counterparts. The reasons for this sex disparity are incompletely understood. We sought to examine if pre-diabetes (preDM) and undiagnosed T2DM are associated with a greater magnitude of CVD risk in women than in men. Methods: We pooled CVD-free individuals (N=18,745) from the Atherosclerosis Risk in Communities, the Multi-Ethnic Study of Atherosclerosis, and the Jackson Heart Study. CVD outcomes included incident coronary heart disease (CHD) (myocardial infarction, CHD death, or cardiac procedures including percutaneous coronary interventions, bypass surgery, or coronary revascularization), stroke (ischemic or hemorrhagic stroke), and a composite atherosclerotic CVD (ASCVD) (any CHD condition or stroke). Multivariable Cox models examined the outcomes associated with preDM (fasting glucose [FG] 100-125 mg/dL or HbA1c 5.7-6.4%) or undiagnosed T2DM (FG ≥126 mg/dL or HbA1c ≥6.5% and without a DM diagnosis or anti-diabetes medication use) adjusted for age, race/ethnicity, education, BMI, blood pressure, total cholesterols, smoking, anti-hypertensive and lipid-lowering medications, and cohort indicator. An interaction term sex x preDM or undiagnosed DM was added to models to test the sex modifying effect. We consider p-interaction 〈 0.2 as significant. Results: During a median follow-up of 17 years, the adjusted model showed that preDM was significantly associated with a higher risk of CHD (Hazard ratio 1.09, 95%CI 1.04-1.14), stroke (1.08, 1.04-1.13), and ASCVD (1.09, 1.04-1.14) in women, but not in men (1.04, 0.99-1.1 for CHD, 1.03, 0.98-1.08 for stroke, and 1.03, 0.98-1.09 for ASCVD, respectively). Undiagnosed T2DM was significantly associated with the risk of CHD (1.27, 1.16-1.4 in women and 1.17, 1.05-1.3 in men), stroke (1.32, 1.21-1.45 in women and 1.2, 1.09-1.32 in men), and ASCVD (1.27, 1.16-1.4 in women and 1.15, 1.03-1.29 in men) in both sexes but with more pronounced effect in women (P-interactions ≤0.11). In racial-stratified analysis, a higher magnitude of CVD risk associated with preDM or undiagnosed DM was also found in non-Hispanic (NH) white women and NH-black women than in their men counterparts. Conclusions: PreDM and undiagnosed DM predispose women to excess CVD risk, possibly due to women’s higher susceptibility to metabolic dysfunction at a lower glucose level and the prolonged unmanaged time for risk factors relative to men. T2DM screening and risk factor control should be enhanced in both sexes to reduce future CVD risk, particularly in women.

    Abstract: The differential effect of comorbidities on COVID-19 severe outcomes by sex has not been fully evaluated. Objective To examine the association of major comorbidities and COVID-19 mortality in men and women separately. Methods We performed a retrospective cohort analysis using a large electronic health record (EHR) database in the U.S. We included adult patients with a clinical diagnosis of COVID-19 who also had necessary information on demographics and comorbidities from January 1, 2016 to October 31, 2021. We defined comorbidities by the Charlson Comorbidity Index (CCI) using ICD-10 codes at or before the COVID-19 diagnosis. We conducted logistic regressions to compare the risk of death associated with comorbidities stratifying by sex. Results A total of 121,342 patients were included in the final analysis. We found significant sex differences in the association between comorbidities and COVID-19 death. Specifically, moderate/severe liver disease, dementia, metastatic solid tumor, and heart failure and the increased number of comorbidities appeared to confer a greater magnitude of mortality risk in women compared to men. Conclusions Our study suggests sex differences in the effect of comorbidities on COVID-19 mortality and highlights the importance of implementing sex-specific preventive or treatment approaches in patients with COVID-19.

    Abstract: Background: Early menopause may be associated with higher cardiovascular disease (CVD) risk due to the early cessation of estrogens protection. The presence of diabetes (DM) coupled with early menopause may result in even greater CVD risk in postmenopausal women. We compared CVD risk in women with early vs. normal age menopause with and without DM. Methods: We pooled data from the Atherosclerosis Risk in Communities Study, the Multi-Ethnic Study of Atherosclerosis, and the Jackson Heart Study. Women with data on menopausal status, age at menopause and DM (yes/no) were included. We excluded pre- or peri-menopausal women, those with hysterectomy/oophorectomy or prevalent CVD. Outcomes were incident coronary heart disease (CHD), ischemic or hemorrhagic stroke, heart failure (HF), and a composite CVD outcome (CHD, stroke or HF). Cox models examined the risk associated with early ( & lt;45 yrs) vs. normal age (≥45 yrs) menopause. Covariates included baseline age, race, education, BMI, blood pressure, cholesterol, smoking, alcohol consumption, and hormone therapy use. Results: During a median follow-up of 15 yrs for 5964 postmenopausal women, 684 CHD, 434 stroke, 962 HF and 1535 CVD events occurred. In adjusted models, women with early menopause had elevated risk of CHD (Hazard ratio 1.12, 95% CI 1.03-1.22), stroke (1.09, 1.01-1.18) and HF (1.09, 1.00-1.19) compared to those with normal age menopause. DM was a significant effect modifier to the relationship between early menopause and CHD, stroke or CVD (P for interaction ≤0.05). HRs for early menopause and the outcomes were greater in diabetic than nondiabetic women (CHD 1.34, 1.02-1.78 vs. 1.10, 1.00-1.20; stroke 1.26, 0.98-1.61 vs. 1.07, 0.98-1.16; CVD 1.41, 1.01-1.95 vs. 1.04, 0.94-1.14). Conclusion: Early menopause increases risk for CVD in postmenopausal women; DM places this group at even higher CVD risk. Attention to CVD risk monitoring and management in women with early menopause, with and without diabetes, should be considered. Disclosure Y. Yoshida: None. Z. Chen: None. R. L. Baudier: None. M.
