Risk Factors for Coronavirus Disease 2019 Hospitalization and Vaccination Impact Among Pediatric Solid Organ Transplant Recipients in the United States
ABSTRACT Background While vaccination is a key strategy to mitigate the severity of coronavirus disease 2019 (COVID‐19) in children, the risk factors for symptomatic, medically attended (hereon referred to as “symptomatic”) COVID‐19 and the impact of vaccination are not well defined among pediatric solid organ transplant recipients (PSOTR). Methods PSOTR aged six months through 21 years at 11 centers in the Pediatric Infectious Diseases Transplant Network (PIDTRAN) were analyzed retrospectively for symptomatic COVID‐19 between July 2021 and May 2023. Using a Cox proportional hazards model, risk factors associated with COVID‐19‐associated hospitalization, in‐hospital oxygen use, mechanical ventilation, and the impact of COVID‐19 vaccination were analyzed. Results Of 1370 PSOTR, 410 (29%) had symptomatic COVID‐19 infection. Among those with symptomatic infection, 115 (28%) were hospitalized, 35 required in‐hospital oxygen, and three required mechanical ventilation. In the study, 45% were unvaccinated against COVID‐19. Compared to unvaccinated PSOTR, incompletely vaccinated PSOTR had 56% lower hazard (95% CI 0.26, 0.72, p = 0.001) of COVID‐19‐associated hospitalization whereas completely vaccinated did not have a statistically significant difference in hazard of hospitalization. Receipt of at least one dose of the bivalent vaccine was also associated with 92.5% lower hazard (95% CI 0.010, 0.55, p = 0.011) of hospitalization. Risk factors for hospitalization included chronic kidney disease, underlying heart disease, neurodevelopmental delay, and lymphocytopenia. Conclusions Most PSOTR with symptomatic COVID‐19 did not require hospitalization or respiratory support. Several comorbidities and lymphocytopenia are associated with severe COVID‐19 in PSOTR. COVID‐19 vaccination, mostly, protected PSOTR against COVID‐19‐associated hospitalization, but vaccine uptake among PSOTR was low. image
Association of Socioeconomic Status With Life's Essential 8 in the National Health and Nutrition Examination Survey: Effect Modification by Sex
Background Higher scores for the American Heart Association Life's Essential 8 (LE8) metrics, blood pressure, cholesterol, glucose, body mass index, physical activity, smoking, sleep, and diet, are associated with lower risk of chronic disease. Socioeconomic status (SES; employment, insurance, education, and income) is associated with LE8 scores, but there is limited understanding of potential differences by sex. This analysis quantifies the association of SES with LE8 for each sex, within Hispanic Americans, non‐Hispanic Asian Americans, non‐Hispanic Black Americans, and non‐Hispanic White Americans. Methods and Results Using cross‐sectional data from the National Health and Nutrition Examination Survey, years 2011 to 2018, LE8 scores were calculated (range, 0–100). Age‐adjusted linear regression quantified the association of SES with LE8 score. The interaction of sex with SES in the association with LE8 score was assessed in each racial and ethnic group. The US population representatively weighted sample (13 529 observations) was aged ≥20 years (median, 48 years). The association of education and income with LE8 scores was higher in women compared with men for non‐Hispanic Black Americans and non‐Hispanic White Americans ( P for all interactions <0.05). Among non‐Hispanic Asian Americans and Hispanic Americans, the association of SES with LE8 was not different between men and women, and women had greater LE8 scores than men at all SES levels (eg, high school or less, some college, and college degree or more). Conclusions The factors that explain the sex differences among non‐Hispanic Black Americans and non‐Hispanic White Americans, but not non‐Hispanic Asian Americans and Hispanic Americans, are critical areas for further research to advance cardiovascular health equity.
Role of Sex in the Association of Socioeconomic Status With Cardiovascular Health in Black Americans: The Jackson Heart Study
Background Socioeconomic status (SES) is associated with cardiovascular health (CVH). Potential differences by sex in this association remain incompletely understood in Black Americans, where SES disparities are posited to be partially responsible for cardiovascular inequities. The association of SES measures (income, education, occupation, and insurance) with CVH scores was examined in the Jackson Heart Study. Methods and Results American Heart Association CVH components (non–high‐density‐lipoprotein cholesterol, blood pressure, diet, tobacco use, physical activity, sleep, glycemia, and body mass index) were scored cross‐sectionally at baseline (scale: 0–100). Differences in CVH and 95% CIs (Estimate, 95% CI) were calculated using linear regression, adjusting for age, sex, and discrimination. Heterogeneity by sex was assessed. Participants had a mean age of 54.8 years (SD 12.6 years), and 65% were women. Lower income, education, occupation (non‐management/professional versus management/professional occupations), and insurance status (uninsured, Medicaid, Veterans Affairs, or Medicare versus private insurance) were associated with lower CVH scores (all P <0.01). There was heterogeneity by sex, with greater magnitude of associations of SES measures with CVH in women versus men. The lowest education level (<high school) versus highest (>high school) was associated with 8.8‐point lower (95% CI: −10.2 to −7.3) and 5.4‐point lower (95% CI: −7.2 to −3.6) CVH scores in women and men, respectively (interaction P =0.003). The lowest (<25 000) versus highest level of income (≥$75 000) was associated with a greater reduction in CVH scores in women than men (interaction P =0.1142). Conclusions Among Black Americans, measures of SES were associated with CVH, with a greater magnitude in women compared with men for education and income. Interventions aimed to address CVH through SES should consider the role of sex.
Association of Socioeconomic Status With Life's Essential 8 Varies by Race and Ethnicity
Background The American Heart Association's Life's Essential 8 (LE8) are 8 risk factors for cardiovascular disease, with poor attainment across all racial, ethnic, and socioeconomic groups. Attainment is lowest among Americans of low socioeconomic status (SES). Evidence suggests the association of SES with LE8 may vary by race and ethnicity. Methods and Results The association of 4 SES categories (education, income‐to‐poverty line ratio, employment, insurance) with LE8 was computed in age‐adjusted linear regression models, with an interaction term for race and ethnicity, using National Health and Nutrition Examination Survey data, years 2011 to 2018. The sample (n=13 529) had a median age of 48 years (51% female) with weighting to be representative of the US population. The magnitude of positive association of college education (relative to ≤high school) with LE8 was greater among non‐Hispanic White Americans (NHWA) compared with non‐Hispanic Black Americans, Hispanic Americans, and non‐Hispanic Asian Americans (all interactions P <0.001). NHWA had a greater magnitude of positive association of income‐to‐poverty line ratio with LE8, compared with non‐Hispanic Black Americans, Hispanic Americans, and non‐Hispanic Asian Americans (all interactions P <0.001). NHWA with Medicaid compared with private insurance had a greater magnitude of negative association with LE8 compared with non‐Hispanic Black Americans, non‐Hispanic Asian Americans, or Hispanic Americans (all interactions P <0.01). NHWA unemployed due to disability or health condition (compared with employed) had a greater magnitude of negative association with LE8 than non‐Hispanic Black Americans, non‐Hispanic Asian Americans, or Hispanic Americans (all interactions P <0.05). Conclusions The magnitude of association of SES with LE8 is greatest among NHWA. More research is needed on SES's role in LE8 attainment in minority group populations.
Replication and validation of genetic polymorphisms associated with survival after allogeneic blood or marrow transplant
Key PointsCandidate SNP associations with survival outcomes after URD transplant are most likely false-positive findings. Over 85% of candidate SNPs are not linked to a biochemical function; of those that are, about half are not linked to the candidate gene.
