Fear of Deportation and Associations with Mental Health Among Michigan Residents of Middle Eastern & North African Descent.

Anti-immigrant rhetoric and immigration policy enforcement in the United States over the last 2 decades has increased attention to fear of deportation as a determinant of poor health. We describe its association with mental health outcomes among Middle East and North African (MENA) residents of Michigan. Using a convenience sample of MENA residents in Michigan (n = 397), we conducted bivariate and multiple variable regression to describe the prevalence of deportation worry and examine the relationship between deportation worry and depressive symptoms (PHQ-4 scores).

The Association of Unfairness with Mental and Physical Health in a Multiethnic Sample of Adults: Cross-sectional Study.

Background: Two psychosocial constructs that have shown consistent associations with negative health outcomes are discrimination and perceived unfairness.

Objective: The current analyses report the effects of discrimination and unfairness on medical, psychological, and behavioral outcomes from a recent cross-sectional survey conducted in a multiethnic sample of adults in Michigan.

Methods: A cross-section survey was collected using multiple approaches: community settings, telephone-listed sample, and online panel.

Development of an Ethnic Identity Measure for Americans of Middle Eastern and North African Descent: Initial Psychometric Properties, Sociodemographic, and Health Correlates.

Background: Southeast Michigan is home to the second largest Middle Eastern and North African (MENA) US population. There is increasing interest in understanding correlates of psychosocial outcomes and health behaviors in this growing population. One potentially important health correlate is ethnic identity (EI).

Study protocol: A Randomized Controlled Trial of a Comprehensive Breast Cancer Treatment Patient Decision Tool (iCanDecide).

Background: Patients newly diagnosed with breast cancer face a series of complex decisions regarding locoregional and systemic treatment. There is a need to improve the quality of locoregional and systemic decisions for breast cancer patients, and to help patients understand the role of evaluative tests in this decision process. We are now conducting a randomized controlled trial (RCT) of an online decision tool-called iCanDecide, which we expect will help patients with these difficult decisions.

Programmed death-1 controls T cell survival by regulating oxidative metabolism.

The coinhibitory receptor programmed death-1 (PD-1) maintains immune homeostasis by negatively regulating T cell function and survival. Blockade of PD-1 increases the severity of graft-versus-host disease (GVHD), but the interplay between PD-1 inhibition and T cell metabolism is not well studied. We found that both murine and human alloreactive T cells concomitantly upregulated PD-1 expression and increased levels of reactive oxygen species (ROS) following allogeneic bone marrow transplantation.

Effector T cells require fatty acid metabolism during murine graft-versus-host disease.

Activated T cells require increased energy to proliferate and mediate effector functions, but the metabolic changes that occur in T cells following stimulation in vivo are poorly understood, particularly in the context of inflammation. We have previously shown that T cells activated during graft-versus-host disease (GVHD) primarily rely on oxidative phosphorylation to synthesize adenosine 5'-triphosphate. Here, we demonstrate that alloreactive effector T cells (Teff) use fatty acids (FAs) as a fuel source to support their in vivo activation.

Mutants of listeriolysin O for enhanced liposomal delivery of macromolecules.

Delivery of macromolecules into the cytosolic space of eukaryotic cells is a pressing challenge in biopharmaceutics. Macromolecules are often encapsulated into liposomes for protection and improved distribution, but the their size often induces endocytosis of the vehicle at the target site, leading to degradation of the cargo. Listeriolysin O is a key virulence factor of Listeria monocytogenes that forms pores in the endosomal membrane, ultimately allowing the bacterium to escape into the cytosol.
