Background and purpose: In-hospital stroke-onset assessment and management present numerous challenges, especially in community hospitals. Comprehensive analysis of key stroke care metrics in community-based primary stroke centers is under-studied. Methods: Medical records were reviewed for patients admitted to a community hospital for non-cerebrovascular indications and for whom a stroke alert was activated between 2013 and 2019. Demographic, clinical, radiologic and laboratory information were collected for each incident stroke. Descriptive statistical analysis was employed. When applicable, Kruskal-Wallis and Chi-Square tests were used to compare median values and categorical data between pre-specified groups. Statistical significance was set at alpha = 0.05. Results: There were 192 patients with in-hospital stroke-alert activation; mean age (SD) was 71.0 years (15.0), 49.5% female. 51.6% (99/192) had in-hospital ischemic and hemorrhagic stroke. The most frequent mechanism of stroke was cardioembolism. Upon stroke activation, 45.8% had ischemic stroke while 40.1% had stroke mimics. Stroke team response time from activation was 26 minutes for all in-hospital activations. Intravenous thrombolysis was utilized in 8% of those with ischemic stroke; 3.4% were transferred for consideration of endovascular thrombectomy. In-hospital mortality was 17.7%, and the proportion of patients discharged to home was 34.4% for all activations. Conclusion: The in-hospital stroke mortality was high, and the proportions of patients who either received or were considered for acute intervention were low. Quality improvement targeting increased use of acute stroke intervention in eligible patients and reducing hospital mortality in this patient cohort is needed.

Introduction: We examined the association between androgen deprivation therapy (ADT) use and the risk of mild cognitive impairment (MCI) among prostate cancer patients. Methods: We included 241 cognitively unimpaired men, aged 70 to 90, with a history of prostate cancer before enrollment in the population-based Mayo Clinic Study of Aging. Using the Rochester Epidemiology Project medical records-linkage system, ADT use and length of exposure were abstracted. Follow-up visits occurred every 15 months and MCI diagnoses were made based on clinical consensus. Cox proportional hazards models, with age as the timescale, were used to examine the association between ADT use (yes/no) and length of exposure with the risk of MCI adjusting for education, apolipoprotein E, depression, and the Charlson Index score. Results: There was no association between any ADT use (27.8% of participants) and the risk of MCI in the multivariable model [hazard ratio (HR), 1.25; 95% confidence interval (CI), 0.75-2.10]. Although not significant, there was an ADT dose-response relationship for risk of MCI: <5 years versus no use (HR, 1.08; 95% CI, 0.60-1.96) and ≥5 years versus not use (HR, 1.89; 95% CI, 0.83-4.27). Conclusion: ADT use among prostate cancer patients was not associated with an increased risk of developing MCI.

Introduction: The association of prostate cancer and androgen deprivation therapy (ADT) use with the odds of developing mild cognitive impairment (MCI) was determined in men from the population-based Mayo Clinic Study of Aging (MCSA). Methods: The study included 2513 men (mean age of 73.1 y) enrolled in the MCSA. A history of prostate cancer, ADT use, and length of ADT exposure before their first MCSA visit was abstracted using the Rochester Epidemiology Project medical records-linkage system. MCI was diagnosed at the baseline visit. Logistic regression was used to determine whether prostate cancer and ADT use was associated with odds of MCI. Results: Of the 2513 participants, 349 (13.9%) had a history of prostate cancer; among whom 99 (28.3%) were treated with ADT before MCSA enrollment. There were 382 (15.2%) with a diagnosis of MCI. In the univariate logistic regression models, prostate cancer (odds ratio, 1.50; 95% confidence interval, 1.12-2.00), and ADT exposure (odds ratio, 1.57; 95% confidence interval, 0.96-2.58) were associated with higher odds of MCI. These associations were greatly attenuated and not significant in multivariable models. Conclusions: Neither a diagnosis of prostate cancer nor ADT use was associated with odds of MCI in this cross-sectional population-based study.
