Further evaluation of this relationship is warranted.Background Chronic aortic regurgitation (AR) can be associated with myocardial scarring. It is unknown if scarring in AR is linked to poor outcomes and whether aortic valve replacement impacts this association. We investigated the relationship of myocardial scarring to mortality in chronic AR using cardiac magnetic resonance. Methods and Results We enrolled patients with moderate or greater AR between 2009 and 2019 and performed a blinded assessment of left ventricle remodeling, AR severity, and presence and extent of myocardial scarring by late gadolinium enhancement. The primary outcome was all-cause mortality. We followed 392 patients (median age 62 [interquartile range, 51-71] years), and 78.1% were men, and 25.8% had bicuspid valves. Median aortic valve regurgitant volume was 39 mL (interquartile range, 30-60). Myocardial scar was present in 131 (33.4%) patients. Aortic valve replacement was performed in 165 (49.1%) patients. During follow-up, up to 10.8 years (median 32.3 months [interquartile range, 9.8-69.5]), 51 patients (13%) died. Presence of myocardial scar (hazard ratio [HR], 3.62; 95% CI, 2.06-6.36; P less then 0.001), infarction scar (HR, 4.94; 95% CI, 2.58-9.48; P less then 0.001), and noninfarction scar (HR, 2.75; 95% CI, 1.39-5.44; P less then 0.004) were associated with mortality. In multivariable analysis, the presence of scar remained independently associated with death (HR, 2.53; 95% CI, 1.15-5.57; P=0.02). Among patients with myocardial scar, aortic valve replacement was independently associated with a lower risk of mortality (HR, 0.34; 95% CI, 0.12-0.97; P=0.03), even after adjustment for confounders. Conclusions In aortic regurgitation, myocardial scar is independently associated with a 2.5-fold increase risk in mortality. Aortic valve replacement was associated with a reduction in risk of mortality in patients with scarring.US-Mexico border communities are uniquely vulnerable to human immunodeficiency virus (HIV) transmission given the economic and social challenges these communities face. We surveyed low-income, predominantly Latinx residents receiving sexually transmitted infection testing and/or HIV/acquired immune deficiency syndrome (AIDS) care in the lower Rio Grande Valley of southernmost Texas about their experiences of food insecurity. Participants aged 18 years and over took a self-administered survey available in English or Spanish in a clinic waiting room (N = 251). Ordinary least squares regression results suggested that those with a prior HIV/AIDS diagnosis reported a response for food insecurity that was approximately 0.67 points higher than peers without a prior HIV/AIDS diagnosis (coefficient = 0.67; p  less then  0.05), even when adjusting for sociodemographic characteristics, social support, perceived discrimination, and neighborhood environment. Interaction results between age and HIV status indicated that younger individuals living with HIV/AIDS experienced uniquely higher food insecurity; those who reported a prior HIV/AIDS diagnosis experienced an additional reduction in food insecurity by approximately 0.06 points for each additional year of age (age × HIV/AIDS interaction coefficient = -0.06; p less then 0.05). Community programs serving low-income populations should consider screening for and intervening on food insecurity, especially among young adults living with HIV/AIDS.Background Upstroke time is the transit time from the nadir to peak of the waveform of pulse volume recording. The purpose of this study was to determine whether upstroke time at the ankle is a useful vascular marker for detecting patients with advanced atherosclerosis in combination with ankle-brachial index (ABI). Methods and Results We measured upstroke time and ABI in 2313 subjects (mean age, 61.2±15.3 years). The prevalence of coronary artery disease (CAD) was significantly higher in patients with prolonged upstroke time (≥180 ms) than in subjects with normal upstroke time ( less then 180 ms) (29.6% versus 11.8%; P less then 0.001), with a significant association between prolonged upstroke time and an increased risk of CAD (odds ratio [OR], 1.61; 95% CI, 1.07-2.44; P=0.02). In 1954 subjects with normal ABI (1.00 ≤ ABI ≤ 1.40), the prevalence of CAD was significantly higher in patients with prolonged upstroke time than in subjects with normal upstroke time (29.5% versus 10.6%; P less then 0.001), with a significant association between prolonged upstroke time and CAD (OR, 2.33; 95% CI, 1.41-3.87; P=0.001), whereas there was no significant association between upstroke time and CAD in subjects with low ABI ( less then 1.00) (OR, 1.24; 95% CI, 0.72-2.16; P=0.44). Conclusions Upstroke time may be a useful vascular marker for detecting patients with CAD, especially in subjects with normal ABI who are usually considered not to have advanced atherosclerosis by ABI measurement alone. More attention should be paid to upstroke time for detecting patients with advanced atherosclerosis.

Methods and Results We conducted a cross-sectional study of hospitalized patients with atrial fibrillation using the Get With The Guidelines-Atrial Fibrillation registry from 2013 to 2019. We identified patients ≥65 years and eligible for OAC therapy. Using 16 available comorbidity categories, patients were stratified by morbidity burden. A multivariable logistic regression model was used to determine the odds of receiving OAC prescription at discharge by morbidity burden. Selleck L-α-Phosphatidylcholine We included 34 174 patients with a median (interquartile range) age of 76 (71-83) years, 56.6% women, and 41.9% were not anticoagulated at admission. Of these patients, 38.6% had 0 to 2 comorbidities, 50.7% had 3 to 5 comorbidities, and 10.7% had ≥6 comorbidities. The overall discharge OAC prescription was high (85.6%). The prevalence of patients with multimorbidity increased from 59.
