ABSTRACT
AIM: Myocardial infarction remains the leading cause of heart failure. The adult human heart lacks the capacity to undergo endogenous regeneration. New blood vessel growth is integral to regenerative medicine necessitating a comprehensive understanding of the pathways that regulate vascular regeneration. We sought to define the transcriptomic dynamics of coronary endothelial cells following ischaemic injuries in the developing and adult mouse and human heart and to identify new mechanistic insights and targets for cardiovascular regeneration. METHODS AND RESULTS: We carried out a comprehensive meta-analysis of integrated single-cell RNA-sequencing data of coronary vascular endothelial cells from the developing and adult mouse and human heart spanning healthy and acute and chronic ischaemic cardiac disease. We identified species-conserved gene regulatory pathways aligned to endogenous neovascularization. We annotated injury-associated temporal shifts of the endothelial transcriptome and validated four genes: VEGF-C, KLF4, EGR1, and ZFP36. Moreover, we showed that ZFP36 regulates human coronary endothelial cell proliferation and defined that VEGF-C administration in vivo enhances clonal expansion of the cardiac vasculature post-myocardial infarction. Finally, we constructed a coronary endothelial cell meta-atlas, CrescENDO, to empower future in-depth research to target pathways associated with coronary neovascularization. CONCLUSION: We present a high-resolution single-cell meta-atlas of healthy and injured coronary endothelial cells in the mouse and human heart, revealing a suite of novel targets with great potential to promote vascular regeneration, and providing a rich resource for therapeutic development.

Between 1935 and 1950 the neurology was presented and developed in Mexico. It happened by two ways: the arrival of Spanish neuroscience researchers in Mexico exiled due the Civil War; and the presence of Mexican doctors that had specialized in neurosurgery in the United States. The article discusses historiographic points of view that stress the importance of the Spanish exiled doctors, but neglect the important role of native doctors in the emergence of Mexican neurology. It states that there was an integration process by both parts, where Mexicans tried to satisfy care needs while the Spanish had to find or create working spaces to belong to.

Se discuten algunas posiciones historiográficas que hablan de la importancia de los españoles exiliados en este acontecer, pero que no han expuesto el relevante papel de los nativos en el surgimiento de la neurología mexicana. Se afirma la existencia de un proceso de integración de ambas partes, donde los nativos buscaron satisfacer necesidades asistenciales mientras que los exiliados tuvieron que encontrar y crear espacios dónde insertarse.

BACKGROUND: As health care reform continues within the United States, navigators may play increasingly diverse and vital roles across the health care continuum. The growing interest in patient navigation programs for underserved populations calls for detailed descriptions of intervention components to facilitate implementation and dissemination efforts. METHODS: In Chicago's Chinatown, Chinese immigrant women face language, cultural, and access barriers in obtaining breast and cervical cancer screening and follow-up. These barriers spurred the research partnership between Northwestern University, the Chinese American Service League, Mercy Hospital & Medical Center, and Rush University Medical Center to formalize the Chinatown Patient Navigation Collaborative for adapting and implementing previously developed patient navigation models. RESULTS: In this report, we describe the adaptation of patient navigation to build the Chinatown Patient Navigation Collaborative's community-based patient navigation program for breast and cervical cancer. We offer insights into the roles of community patient navigators in safety net hospital and underserved Chinese immigrant communities, and describe implications for patient navigation initiatives to maximize community benefits by improving access to health care for vulnerable populations. CONCLUSIONS: Our adaptation and implementation of a patient navigation intervention in Chicago's Chinatown illustrates promising approaches for future navigator research.
ABSTRACT
INTRODUCTION: Low rates of adherence to self-management behaviors are common among patients with COPD. Health literacy and cognitive abilities may influence engagement in self-management behaviors. We sought to assess the association between health literacy and cognitive abilities with self-management behaviors in patients with COPD. METHODS: We conducted an observational cohort study among American adults with COPD in New York, New York, and Chicago, Illinois. Outcomes included adherence to COPD medication, metered dose inhaler (MDI) and dry powder inhaler (DPI) technique, receipt of vaccination, and routine healthcare appointments. Health literacy was measured with the Short Test of Functional Health Literacy in Adults. Cognitive function was assessed in terms of global, fluid (working memory, processing speed, executive function) and crystallized (verbal) ability. RESULTS: Adequate health literacy was associated with adequate adherence to COPD medications (OR 1.46; 95% CI, 1.02-2.08), correct MDI (OR 1.66; 95% CI, 1.13-2.44) and DPI (OR 2.17; 95% CI, 1.30-3.64) technique. Fluid abilities were also associated with medication behaviors and visiting a regular healthcare provider, while crystalized abilities were not. Global cognitive abilities were associated with correct inhaler technique. No other associations were found with non-medication self-management behaviors. CONCLUSIONS: COPD patients with limited health literacy and deficits in fluid cognitive abilities have lower rates of adherence and poorer inhaler technique than individuals with adequate health literacy and greater fluid cognitive abilities. These findings highlight the importance of considering the health literacy level and cognitive ability when caring for and educating patients with COPD.

OBJECTIVE: To determine the prevalence of mild visual impairment (MVI) among urban older adults in primary care settings, and ascertain whether MVI was a risk factor for inadequate performance on self-care health tasks. METHOD: We used data from a cohort of 900 older adults recruited from primary care clinics. Self-management skills were assessed using the Comprehensive Health Activities Scale, and vision with corrective lenses was assessed with the Snellen. We modeled visual acuity predicting health task performance with linear regression. RESULTS: Normal vision was associated with better overall health task performance ( p = .004). Individuals with normal vision were more likely to recall health information conveyed via multimedia ( p = .02) and during a spoken encounter ( p = .04), and were more accurate in dosing multi-drug regimens ( p = .05). DISCUSSION: MVI may challenge the performance of self-care behaviors. Health care systems and clinicians should consider even subtle detriments in visual acuity when designing health information, materials, and devices.

BACKGROUND: We sought to investigate the degree to which cognitive skills explain associations between health literacy and asthma-related medication use among older adults with asthma. METHODS: Patients aged ≥ 60 years receiving care at eight outpatient clinics (primary care, geriatrics, pulmonology, allergy, and immunology) in New York, New York, and Chicago, Illinois, were recruited to participate in structured, in-person interviews as part of the Asthma Beliefs and Literacy in the Elderly (ABLE) study (n = 425). Behaviors related to medication use were investigated, including adherence to prescribed regimens, metered-dose inhaler (MDI) technique, and dry powder inhaler (DPI) technique. Health literacy was measured using the Short Test of Functional Health Literacy in Adults. Cognitive function was assessed in terms of fluid (working memory, processing speed, executive function) and crystallized (verbal) ability. RESULTS: The mean age of participants was 68 years; 40% were Hispanic and 30% non-Hispanic black. More than one-third (38%) were adherent to their controller medication, 53% demonstrated proper DPI technique, and 38% demonstrated correct MDI technique. In multivariable analyses, limited literacy was associated with poorer adherence to controller medication (OR, 2.3; 95% CI, 1.29-4.08) and incorrect DPI (OR, 3.51; 95% CI, 1.81-6.83) and MDI (OR, 1.64; 95% CI, 1.01-2.65) techniques. Fluid and crystallized abilities were independently associated with medication behaviors. However, when fluid abilities were added to the model, literacy associations were reduced. CONCLUSIONS: Among older patients with asthma, interventions to promote proper medication use should simplify tasks and patient roles to overcome cognitive load and suboptimal performance in self-care.

BACKGROUND: Age and race-related disparities in technology use have been well documented, but less is known about how health literacy influences technology access and use. OBJECTIVE: To assess the association between patients' literacy skills and mobile phone ownership, use of text messaging, Internet access, and use of the Internet for health-related purposes. METHODS: A secondary analysis utilizing data from 1077 primary care patients enrolled in two, multisite studies from 2011-2013. Patients were administered an in-person, structured interview. RESULTS: Patients with adequate health literacy were more likely to own a mobile phone or smartphone in comparison with patients having marginal or low literacy (mobile phone ownership: 96.8 vs. 95.2 vs. 90.1%, respectively, P < 0.001; smartphone ownership: 70.6 vs. 62.5 vs. 40.1%, P < 0.001) and to report text messaging (78.6 vs. 75.2 vs. 53.1%, P < 0.001). They were also more likely to have access to the Internet from their home (92.1 vs. 74.7 vs. 44.9%, P < 0.001) and to report using the Internet for email (93.0 vs. 75.7 vs. 38.5%, P < 0.001), browsing the web (93.9 vs. 80.2 vs. 44.5%, P < 0.001), accessing health information (86.3 vs. 75.5 vs. 40.8%, P < 0.001), and communicating with providers (54.2 vs. 29.8 vs. 13.0%, P < 0.001). Relationships remained significant in multivariable analyses controlling for relevant covariates. CONCLUSIONS: Results reveal that literacy-related disparities in technology access and use are widespread, with lower literate patients being less likely to own smartphones or to access and use the Internet, particularly for health reasons. Future interventions should consider these disparities and ensure that health promotion activities do not further exacerbate disparities.
