Utilization of Traditional Complementary and Alternative Medicine Across Ethnically Diverse Asian Americans.

We conducted an analysis to identify factors influencing the use of traditional complementary and alternative medicine (TCAM), with a particular emphasis on ethnic variations. Using the 2015 Asian American Quality of Life survey (N = 2,609), logistic regression analyses were performed, considering acculturation, health status, healthcare accessibility/utilization, and socio-demographic factors. Ethnicity, specifically being Chinese or Korean Americans, having chronic medical conditions, experiencing unmet healthcare needs, and having regular check-ups were significant predictors of TCAM use among Asian Americans as a whole. However, when we delved into sub-ethnic groups, different patterns were found. Among Vietnamese and Filipino Americans, having unmet healthcare needs emerged as the most prominent predictor of TCAM use. Furthermore, acculturation level and English proficiency were significant in predicting Vietnamese and Filipino Americans' TCAM use, with the direction varying by sub-ethnicity. Being old emerged as a predictor of TCAM use for Chinese, Indian, Korean, and 'other' Americans. Our findings underscore the importance of adopting an ethnically sensitive approach when addressing the healthcare needs of diverse Asian American populations.

Anti-neuroinflammatory effects of Ephedra sinica Stapf extract-capped gold nanoparticles in microglia.

Background: Combination therapy remains a promising strategy for treating neurodegenerative diseases, although green synthesis of gold nanoparticles for treating chronic neuroinflammation and studying their efficacy in treating neuroinflammation-mediated neurodegenerative diseases is not well assessed. Results: Here, Ephedra sinica Stapf (ES) extract was used as the reducing, capping, and stabilizing agent for gold nanoparticle synthesis. We developed ES extract-capped gold nanoparticles (ES-GNs) and investigated their anti-neuroinflammatory properties in microglia. ES-GNs displayed maximum absorption at 538 nm in ultraviolet-visible spectroscopy. Dynamic light scattering assessment revealed that ES-GN diameter was 57.6±3.07 nm, with zeta potential value of -24.6±0.84 mV. High resolution-transmission electron microscopy confirmed the spherical shape and average diameter (35.04±4.02 nm) of ES-GNs. Crystalline structure of ES-GNs in optimal conditions was determined by X-ray powder diffraction, and elemental gold presence was confirmed by energy-dispersive X-ray spectroscopy. Fourier transform-infrared spectroscopy confirmed gold nanoparticle synthesis using ES. Anti-neuroinflammatory properties of ES-GNs on production of pro-inflammatory mediators (nitric oxide, prostaglandin E2, and reactive oxygen species) and cytokines (tumor necrosis factor-α, IL-1ß, and IL-6) in lipopolysaccharide (LPS)-stimulated microglia were investigated by ELISA and flow cytometry. ES-GNs significantly attenuated LPS-induced production of pro-inflammatory mediators and cytokines, which was related to suppressed transcription and translation of inducible nitric oxide synthase and cyclooxygenase-2, determined by RT-PCR and western blotting. ES-GNs downregulated upstream signaling pathways (IκB kinase-α/ß, nuclear factor-κB, Janus-activated kinase /signal transducers and activators of transcription, mitogen-activated protein kinase , and phospholipase D) of pro-inflammatory mediators and cytokines in LPS-stimulated microglia. Anti-neuroinflammatory properties of ES-GNs were mediated by ES-GNs-induced AMP-activated protein kinase)-mediated nuclear erythroid 2-related factor 2 /antioxidant response element signaling. Conclusion: Collectively, these findings provide a new insight on the role of ES-GNs in treating chronic neuroinflammation-induced neurodegenerative diseases.

Facilitators and Barriers for Advance Care Planning Among Ethnic and Racial Minorities in the U.S.: A Systematic Review of the Current Literature.

Growing evidence suggests a low engagement in advance care planning (ACP) among ethnic minorities in the U.S. The purpose of this study was to synthesize findings from prior research about ACP among ethnic minorities. An extensive literature search was conducted using multiple electronic databases. After applying inclusion criteria, 26 studies were included. Four categories of facilitators and barriers to ACP were identified: (1) Socio-demographic factors, (2) health status, literacy and experiences, (3) cultural values, and (4) spirituality. Socio-demographic factors showed inconsistent findings regarding their association with ACP engagement. Worse health status and knowledge about ACP are common facilitators across ethnic minority groups, whereas mistrust toward the health care system was a barrier only for Blacks. Collectivistic cultural values influenced ACP engagement among Latinos and Asian Americans; however, spirituality/religion played an important role among Blacks. The implications for culturally competent approaches to promote ACP and future research directions are discussed.
