Abstract 96: Temporal Trends in Vascular Risk Factor Burden Among Young Adults With Ischemic Stroke: The Florida Stroke Registry
Abstract only Introduction: While ischemic stroke (IS) in the young (18-55) is thought to have different etiologies than in older patients, a rise in vascular risk factors (VRFs) among young adults may translate to an IS risk profile similar to the older population. We aimed to examine the prevalence of VRFs and temporal trends in VRF burden among young patients presenting with IS. Methods: Data was prospectively collected by Get With the Guidelines-Stroke® hospitals participating in the Florida Stroke Registry between January 2010 and December 2022. Patients aged 18-55 with a diagnosis of IS were included and separated into two age groups: 18-35 and 36-55. VRFs included hypertension, dyslipidemia, obesity, smoking, atrial fibrillation, coronary artery disease, heart failure, diabetes, and sleep apnea. Multimorbidity was defined as having ≥4 VRFs. Results: 47,792 patients with IS were included (43% female, median age 49, 51% white), comprising 4,275 patients aged 18-35 (8.9%) and 43,517 aged 36-55 (91.1%). The prevalence of each VRF was higher among patients aged 36-55 vs 18-35 (all p values <0.001), and only 15.3% of patients aged 36-55 and 40.0% of patients aged 18-35 had 0 VRFs. African American patients with IS had a significantly higher prevalence of multimorbidity than white or non-white Hispanic patients; specifically in those aged 18-35 (6.1% vs 3.5% vs 3.5%, p <0.001), while those aged 36-55 demonstrated a smaller difference (17.6% vs 17.2% vs 15.4% p <0.001).VRF burden worsened across the study period, with an increase in multimorbidity from 11.2% to 21.7% in patients 36-55 (p<0.0001) and from 1.3% to 6.6% in patients 18-35 (p= 0.0006). Conclusions: Increasingly, young stroke patients have traditional VRFs. The prevalence of multimorbidity disproportionately affects African American patients and has significantly increased over the past 12 years. Efforts targeting VRFs reduction must start as early as possible in light of the rise in VRF burden amongst young IS patients

Biofilms on Indwelling Artificial Urinary Sphincter Devices Harbor Complex Microbe–Metabolite Interaction Networks and Reconstitute Differentially In Vitro by Material Type
The artificial urinary sphincter (AUS) is an effective treatment option for incontinence due to intrinsic sphincteric deficiency in the context of neurogenic lower urinary tract dysfunction, or stress urinary incontinence following radical prostatectomy. A subset of AUS devices develops infection and requires explant. We sought to characterize biofilm composition of the AUS device to inform prevention and treatment strategies. Indwelling AUS devices were swabbed for biofilm at surgical removal or revision. Samples and controls were subjected to next-generation sequencing and metabolomics. Biofilm formation of microbial strains isolated from AUS devices was reconstituted in a bioreactor mimicking subcutaneous tissue with a medical device present. Mean patient age was 73 (SD 10.2). All eighteen artificial urinary sphincter devices harbored microbial biofilms. Central genera in the overall microbe–metabolite interaction network were Staphylococcus (2620 metabolites), Escherichia/Shigella (2101), and Methylobacterium-Methylorubrum (674). An rpoB mutation associated with rifampin resistance was detected in 8 of 15 (53%) biofilms. Staphylococcus warneri formed greater biofilm on polyurethane than on any other material type (p < 0.01). The results of this investigation, wherein we comprehensively characterized the composition of AUS device biofilms, provide the framework for future identification and rational development of inhibitors and preventive strategies against device-associated infection
