The paucity of large-scale data exploring the effect of prior bariatric surgery on recurrent stroke outcomes in older individuals with obesity who survived a stroke led us to address the gap, with an emphasis on the risk of recurrent stroke and its trends. Retrospective analysis of the National Inpatient Sample data from 2016 to 2019. Older individuals with obesity who survived a stroke (>65 years) and had a recurrent acute ischemic stroke (AIS) hospitalization, with or without prior bariatric surgery (PBS), were identified using ICD-10 codes. Recurrent stroke trends, demographic characteristics, and comorbidities between the cohorts were compared. Analyzing 643,505 older individuals with obesity who survived a stroke, we identified that 11,820 had undergone PBS. Both groups (no PBS vs. PBS) were predominantly female (59.7 % vs. 73.7 %), identified as white (76.5 % vs. 83.8 %), and covered by Medicare (91.7 % vs. 90.7 %). Diabetes, hyperlipidemia, prior myocardial infarction, and peripheral vascular diseases were more common in those without PBS. In contrast, tobacco use disorder, drug abuse, and valvular diseases were more common in those with PBS. There was no significant difference in the prevalence of hypertension between groups.Between 2016 and 2019, recurrent AIS hospitalizations were less frequent in the PBS group (4 %-2.9 %, p = 0.035) while remaining stable in the other group (4.4 %-4.2 %, p = 0.064). The risk of recurrent AIS hospitalization was less frequent in the PBS cohort (aOR: 0.77, 95 % CI: 0.60-0.98). PBS in older individuals with obesity who survived a stroke was associated with a 23 % lower risk of recurrent AIS hospitalization with a decreasing trend of prevalence since 2016. These findings could influence clinical practice and contribute to developing secondary prevention strategies for recurrent stroke among these patients.

Background: Sickle cell disease (SCD) significantly impacts diverse racial groups, particularly African American and Hispanic persons, who experience notable disparities in healthcare outcomes. Despite the extensive literature on SCD, studies focusing on in-hospital racial inequities remain limited. Methods: We conducted a retrospective analysis using the National Inpatient Sample (NIS) from 2016 to 2020, identifying adult hospitalizations for SCD. Hospitalizations were categorized by race—White, African-American, Hispanic, and Other, and analyzed for demographic variables, admission types, disposition outcomes, and complications. Statistical analyses included chi-square tests and multivariate logistic regression, adjusting for confounders. Results: Of the 1,089,270 identified hospitalizations, 90.31% were African-American. African-American and Hispanic patients exhibited significantly higher non-elective admissions compared to Whites (77.81%). In-hospital mortality was highest among Hispanics (0.82%). Multivariate regression analysis revealed that African-Americans and Others had higher odds of prolonged hospital stays (Adjusted Odds Ratio (AOR): 1.30 and 1.20, respectively). African-Americans and Hispanics also had increased risks of in-hospital complications of SCD. Conclusion: This study highlights substantial racial disparities in SCD hospitalizations, with African Americans and Hispanics facing poorer outcomes compared to Whites. Hispanics also demonstrated increased mortality. These findings underscore the need for targeted healthcare interventions to address racial inequities in SCD management and improve outcomes for all affected populations.
