Background: Little is known about adherence to American Heart Association/American Stroke Association (AHA/ASA) stroke performance measures in developing countries like Peru., Aims: We assessed adherence and determined factors associated with adherence to the AHA/ASA stroke performance measures at a reference center for neurological diseases in Lima, Peru., Methods: We conducted a retrospective chart review of 150 stroke patients admitted to the Neurological Institute of Neurological Science from 2014 to 2016 to ascertain adherence to 15 different AHA/ASA stroke performance measures. Adherence was measured as a simple proportion, with both single and composite measures. Associations were analyzed with nonparametric statistics and multivariate logistic regression., Results: Mean adherence to AHA/ASA stroke performance measures was 47%. We observed a statistically significant relationship between adherence to ischemic stroke performance measures and being married (OR = 3.78, 95% CI: 1.05-13.55), as well as an inverse relationship with an onset of symptoms of greater than 4.5 h prior to arrival at the hospital compared to those with ≤ 4.5 h (OR = 0.14, 95% CI: 0.02-0.97). Compared to patients with a lower National Institutes of Health Stroke Scale (NIHSS) score (<13), those with a score of ≥13 were less likely to have good adherence (OR = 0.11, 95% CI: 0.04-0.31)., Conclusions: The mean composite measure of adherence to internationally recognized standards of stroke management in our Peruvian institution was below the level needed for an achievement award by AHA/ASA. An intervention targeted toward stroke prevention and training could lead to improved outcomes of stroke patients in Peru., Competing Interests: Declaration of Interest None., (Copyright © 2020 Elsevier Inc.

Background: The availability of intravenous tissue plasminogen activator (IV-tPA) remains limited worldwide, especially in low-income countries, where the burden of disability due to ischemic stroke is the highest., Aims: To evaluate outcomes and safety of IV-tPA at the only Peruvian reference institute for neurologic diseases., Methods: We conducted a prospective, observational study of stroke patients who received IV-tPA between 2009 and 2016. We assessed characteristics associated with good outcome (modified Rankine scale 0-2) at 3 months using a multivariate regression model; and factors correlated with clinical improvement (delta National Institute of Health Stroke Scale (NIHSS)) using linear regression., Results: Only 1.98% (39/1,1962) of patients presenting with ischemic stroke received IV-tPA. Nearly half (41%) were younger than 60 years, 56.4 % were men, and most strokes were cardioembolic (46.2%). The majority (64.1%) were treated within 3-4.5 hours. The median NIHSS on admission and discharge was 9 and 4, respectively; 42.1% of patients had an mRS of 0-1 at 3 months. Three patients (7.7%) developed hemorrhagic conversion, and 1 patient died (2.6%). Patients with good outcomes had lower pretreatment systolic blood pressure (138.9 versus 158.1 mm Hg, P < .007), fewer complications during hospitalization (5 versus 9 events, P < .001), shorter hospital stay (14 versus 21 days, P < .03) and, paradoxically, longer last known well -to-door times (148.3 versus 105 minutes, P < .0022). Clinical improvement was associated with shorter door-to-tPA times and obesity., Conclusions: Our findings indicate that IV-tPA has similar safety and outcomes compared to developed countries. All internal metrics (door-to-tPA, door-to-CT, and CT-to-tPA time) improved over time, highlighting areas for future implementation science studies to further expedite the administration of IV-tPA., (Copyright © 2020 Elsevier Inc.

Background: In Peru, there is an ongoing high-incidence HIV epidemic among men who have sex with men (MSM) and transgender women (TW). Sexual concurrency, or having sex with a partner in between two acts of sex with another partner, may be a key factor in onward HIV transmission. In this study, we quantify concurrency, evaluate factors associated with concurrency, and assess condom use with concurrent partners among MSM and TW in Peru., Methods: We conducted a secondary analysis of data from the 2011 Peruvian Biobehavioral Survey. Pearson's Chi-squared test was used to identify individual-level characteristics associated with concurrency. We estimated the association between participant characteristics, concurrent partnerships, partnership type (stable vs. non-stable), and CLAI within the context of concurrent partnerships using multivariate and repeated-measure Poisson regression., Results: 3-month cumulative prevalence of concurrency was higher among TW compared to MSM (30.7% vs 25.2%, p = 0.014). Among those with concurrent stable and non-stable partners, 45% used condoms with both partners (95% CI: 40%-50%) and 30% preferentially had CLAI with the stable partner only (95%CI: 26%-35%). Factors associated with CLAI within the context of concurrent partnerships varied between MSM and TW., Conclusions: Although concurrency is common among TW and MSM in Peru, patterns of concurrency and differential condom use may vary between TW and MSM. Future research may explore differential condom use with stable and non-stable partners to better understand behavioral factors that may alter vulnerability to HIV in TW compared to MSM., Competing Interests: The authors have declared that no competing interests exist.
