Health care for immigrants--implications of Obama's executive action

Undocumented Patients in the Emergency Department: Challenges and Opportunities

In the United States, undocumented residents face unique barriers to healthcare access that render them disproportionately dependent on the emergency department (ED) for care. Consequently, ED providers are integral to the health of this vulnerable population. Yet special considerations, both clinical and social, generally fall outside the purview of the emergency medicine curriculum. This paper serves as a primer on caring for undocumented patients in the ED, includes a conceptual framework for immigration as a social determinant of health, reviews unique clinical considerations, and finally suggests a blueprint for immigration-informed emergency care.

Effects of PARP-1 Deficiency and Histamine H4 Receptor Inhibition in an Inflammatory Model of Lung Fibrosis in Mice

Pulmonary fibrosis is the most frequent form of interstitial lung disease. Effective therapies are not yet available; novel therapeutic approaches are needed for counteracting fibrosis. Poly(ADP-ribose) polymerases are enzymes, involved in DNA repair and cell apoptosis. PARP-1 deficient mice exhibited reduced lung fibrosis in response to bleomycin treatment compared to wild-type controls. Histamine H₄ receptors (H₄Rs) have been recognized as a new target for inflammatory and immune diseases, and H₄R ligands reduced inflammation and oxidative stress in lung tissue. The aim of the study was to evaluate the cross-talk between PARP-1 and H₄R in a model of bleomycin-induced lung fibrosis in PARP-1^−/− and WT mice. Animals were treated with bleomycin or saline by intra-tracheal injection. JNJ7777120, an H₄R antagonist, or VUF8430, an H₄R agonist, were administered i.p for 21 days. Airway resistance to inflation was evaluated, and lung tissues were processed for PARylated protein content, oxidative stress evaluation, and histology of small bronchi. The levels of pro-inflammatory (IL-1β and TNF-α), regulatory (IL-10), and pro-fibrotic (TGF-β) cytokines were evaluated. The deposition of αSMA was determined by immunofluorescence analysis. The results indicate that JNJ7777120 reduces PARylated protein production, decreases oxidative stress damage, and MPO, a marker for leukocyte tissue infiltration, in PARP-1^−/− mice. A significant decrease in the production of both IL-1β and TNF-α and a significant increase in IL-10 levels are observed in mice treated with H₄R antagonist, suggesting a crucial anti-inflammatory activity of JNJ7777120. The smooth muscle layer thickness, the goblet cell relative number, and collagen deposition decreased following JNJ7777120 administration. The H₄R antagonist treatment also reduces TGF-β production and αSMA deposition, suggesting an important role of JNJ7777120 in airway remodeling. Our results show that PARylation is essential for the pathogenesis of pulmonary fibrosis and propose that PARP-1 and H₄Rs are both involved in inflammatory and fibrotic responses. JNJ7777120 treatment, in a condition of PARP-1 inhibition, exerts anti-inflammatory and anti-fibrotic effects, reducing airway remodeling and bronchoconstriction. Therefore, selective inhibition of H₄Rs together with non-toxic doses of selective PARP-1 inhibitors could have clinical relevance for the treatment of idiopathic pulmonary fibrosis.

A Critical Review and Commentary on the Challenges in Engaging HIV-Infected Latinos in the Continuum of HIV Care

Antiretroviral therapy for treatment of HIV infection has become increasingly effective. Persistent poor HIV outcomes in racial and ethnic minority populations in the US call for a closer examination into why Latinos are at significant risk for acquiring and dying from HIV. To improve clinical outcomes and achieve an AIDS-free generation, HIV research must address disparities in HIV outcomes in Latinos, the largest ethnic/racial minority population in the US. Immigrant status as well as cultural factors influence HIV care utilization and are essential to highlight for effective intervention development in Latinos. A better understanding of these individual and contextual factors is critical to developing tailored approaches to engaging Latinos in HIV care. Based on a comprehensive literature review, we offer a framework for understanding what is needed from clinical practice and research to improve engagement in HIV care for US-based Latinos. These findings may have implications for other minority populations.

Access and utilization of healthcare services in Massachusetts, United States: a qualitative study of the perspectives and experiences of Brazilian-born immigrant women

Background

Understanding immigrants’ interactions with the United States (US) healthcare system will likely make it possible to meet their healthcare needs and improve their quality of life in the US. Although challenges to accessing and utilizing healthcare in the US have been identified, there is little information specific to Brazilian-born immigrants’ experiences. Brazilians comprise a fast-growing immigrant population group in the US. The purpose of this study was to explore Brazilian immigrant women’s perspectives and experiences with healthcare services in the US to gain insights into factors amenable to interventions that may contribute to disparities in access to and utilization of services.

Methods

Five focus groups were conducted from April to May in 2015 using a purposeful sampling of Brazilian-born immigrant women living in Massachusetts, US.

Results

Thirty-five women participated in this study. Although participants expressed their overall satisfaction with the US healthcare system, they noted several barriers to care, including sociocultural differences in delivery of care and communication barriers, including inconsistent quality of interpreting services.

Conclusions

This study provides new information on the experiences and challenges faced by Brazilian immigrant women in accessing and utilizing healthcare services in the US and points out opportunities for improving services and the overall health of this immigrant population. Addressing noted sociocultural differences and communication barriers including inconsistent quality of hospital’s interpreting services might enhance Brazilian-born immigrants’ experiences with the healthcare system.

Trends in Disparities in Low-Income Children's Health Insurance Coverage and Access to Care by Family Immigration Status

OBJECTIVE

To examine time trends in disparities in low-income children's health insurance coverage and access to care by family immigration status.

METHODS

We used data from the National Survey of Children's Health in 2003 to 2011-2012, including 83,612 children aged 0 to 17 years with family incomes <200% of the federal poverty level. We examined 3 immigration status categories: citizen children with nonimmigrant parents; citizen children with immigrant parents; and immigrant children. We used multivariable regression analyses to obtain adjusted trends in health insurance coverage and access to care.

RESULTS

All low-income children experienced gains in health insurance coverage and access to care from 2003 to 2011-2012, regardless of family immigration status. Relative to citizen children with nonimmigrant parents, citizen children with immigrant parents had a 5 percentage point greater increase in health insurance coverage (P = .06), a 9 percentage point greater increase in having a personal doctor or nurse (P < .01), and an 11 percentage point greater increase in having no unmet medical need (P < .01). Immigrant children had significantly lower health insurance coverage than other groups. However, the group had a 14 percentage point greater increase in having a personal doctor or nurse (P < .01) and a 26 percentage point greater increase in having no unmet medical need (P < .01) relative to citizen children with nonimmigrant parents.

CONCLUSIONS

Some disparities in access to care related to family immigration status have lessened over time among children in low-income families, although large disparities still exist. Policy efforts are needed to ensure that children of immigrant parents and immigrant children are able to access health insurance and health care.
