Racial and ethnic minorities suffer disproportionately from diabetes-related morbidity and mortality. With the creation of Accountable Care Organizations (ACOs) under the Affordable Care Act, healthcare organizations may have an increased motivation to implement interventions that collaborate with community resources and organizations. As a result, there will be an increasing need for evidence-based strategies that integrate healthcare and community components to reduce diabetes disparities. This paper summarizes the types of community/health system partnerships that have been implemented over the past several years to improve minority health and reduce disparities among racial/ethnic minorities and describes the components that are most commonly integrated. In addition, we provide our recommendations for creating stronger healthcare and community partnerships through enhanced community support.
The availability of safe drug-disposal kiosks, naloxone dispensing at pharmacies, and patient education are key prevention initiatives to address the opioid epidemic and reduce the increasing national burden of opioid overdose. Early results are quantitatively and qualitatively promising.
We identified several factors that motivated collaboration across diverse sectors with health care systems to promote health in a high-poverty, urban setting. Understanding these motivations will be foundational to optimizing meaningful cross-sector collaboration and improving diabetes outcomes in the nation's most vulnerable communities.
alpha2,6-Sialyltransferase (ST6Gal I) functions in the Golgi to terminally sialylate the N-linked oligosaccharides of glycoproteins. Interestingly, rat ST6Gal I is expressed as two isoforms, STtyr and STcys, that differ by a single amino acid in their catalytic domains. In this article, our goal was to evaluate more carefully possible differences in the catalytic activity and intra-Golgi localization of the two isoforms that had been suggested by earlier work. Using soluble recombinant STtyr and STcys enzymes and three asialoglycoprotein substrates for in vitro analysis, we found that the STcys isoform was somewhat more active than the STtyr isoform. However, we found no differences in isoform substrate choice when these proteins were expressed in Chinese hamster ovary cells, and sialylated substrates were detected by lectin blotting. Immuno-fluorescence and immunoelectron microscopy revealed differences in the relative levels of the isoforms found in the endoplasmic reticulum (ER) and Golgi of transiently expressing cells but similar intra-Golgi localization. STtyr was restricted to the Golgi in most cells, and STcys was found in both the ER and Golgi. The ER localization of STcys was especially pronounced with a C-terminal V5 epitope tag. Ultrastructural and deconvolution studies of immunostained HeLa cells expressing STtyr or STcys showed that within the Golgi both isoforms are found in medial-trans regions. The similar catalytic activities and intra-Golgi localization of the two ST6Gal I isoforms suggest that the particular isoform expressed in specific cells and tissues is not likely to have significant functional consequences.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
