RESUMO
Background: During the initial phase of the COVID-19 pandemic, facilities transformed some medical care to virtual appointments. There was a subsequent decline in chronic disease screening and management, as well as cancer screening rates. Observations: COVID-19 vaccine events offered an opportunity to provide face-to-face preventive care to veterans, and mobile vaccine events enabled us to reach rural veterans. In this quality improvement project, we partnered with state and community organizations to reach veterans at large vaccine events, as well as in rural sites and homeless housing. The program resulted in the successful provision of preventive care to 115 veterans at these events, with high follow-up for recommended medical care. In all, 404 clinical reminders were completed and 10 new veterans were enrolled for health care. Important clinical findings included an invasive colorectal cancer, positive HIV point-of-care test, diabetic retinal disease, uncontrolled hypertension, and depression. Conclusions: Vaccine events offer a venue for chronic disease screening, referral, and cancer screening.
RESUMO
Growing evidence suggests that renin angiotensin system (RAS) modulators support cognitive function in various animal models. However, little is known about their long-term effects on the brain structure in aged hypertensive animals with chronic cerebral hypoperfusion as well as which specific domains of cognition are most affected. Therefore, in the current study we examined the effects of Candesartan and Compound 21 (C21) (RAS modulators) on aspects of cognition known to diminish with advanced age and accelerate with hypertension and vascular disease. Outcome measures for sensorimotor and cognitive function were performed using a sequence of tests, all blindly conducted and assessed at baseline and after 4 and 8 weeks of chronic hypoxic hypoperfusion and treatment. Magnetic resonance imaging (MRI) was performed at the end of the 8 week study period followed by animal sacrifice and tissue collection. Both Candesartan and C21 effectively preserved cognitive function and prevented progression of vascular cognitive impairment (VCI) but only candesartan prevented loss of brain volume in aged hypertensive animals. Collectively, our findings demonstrate that delayed administration of RAS modulators effectively preserve cognitive function and prevent the development / progression of VCI in aged hypertensive animals with chronic cerebral hypoperfusion.
