  • Social Determinants of Latina/o Sleep Health: Insights and Implications for Behavioral Interventions

    Alcántara, Carmela; Columbia University (University of Arizona (Tucson, AZ), 2019-01-25)
    Sleep is increasingly recognized as an important behavioral and public health issue for all in the United States (US). Yet, Latina/o sleep health is understudied despite the fact that Latina/os compose 16.3% of the US population, and that sleep problems are prevalent among Latina/os. Additionally, racial/ethnic and language-based disparities in access to safe and effective behavioral health interventions for prevalent sleep-wake disorders persist. In this talk, I will draw from frameworks in psychology, public health, social work, and medicine to discuss recent evidence from my program of research on the relative association of sociocultural stressors and general psychosocial stress with various dimensions of subjectively- and objectively-measured sleep among Latina/os, and discuss implications for behavioral sleep intervention science. Second, I will describe formative work behind an ongoing mixed-methods Hybrid effectiveness-implementation randomized controlled trial that tests a culturally adapted self-guided digital version of cognitive behavioral therapy for insomnia versus usual care in Spanish-speaking Latina/o primary care patients. Finally, I will conclude by discussing future mechanistic and ecological research on the bi-directional relationships between sleep, stress, and self-regulatory processes among Latina/os.

    This paper will identify best-practice recommendations to help nurses better cope with demands of the field, an implementation plan, and an evaluation of the implementation process. This paper explores whether or not nurses working in the intensive care unit (ICU) experience reduced psychological well-being due to aspects of their job such as high mortality rates, ethical dilemmas, and stress. In the world of healthcare, the demand for nurses is at an all time high. However, retention rates of bedside nurses are a direct threat to this demand. The low retention rate of newly licensed registered nurses remains an ongoing challenge not only for the institution but for the quality of care provided to the patients. In 2017, the turnover rate for bedside registered nurses ranged from 6.6% to 28.7%, with a turnover rate for critical care nurses in 2017 of 16.4% (Colosi, 2018). The articles presented in this paper examine the psychological well being of ICU nurses regarding levels of compassion fatigue and burnout and further discuss the effect that high incidences of stress, high mortality rates, ethical dilemmas, and pressure on the nurses to provide their best care have on the nurse’s well-being.

    The Seri indigenous people of Mexico have been living in the desert along the Sea of Cortés for thousands of years. Their territory includes the northern most mixed mangrove estuary in Mexico. After reviewing previous literature about the Seri and the estuary, I developed a set of questions and visited their villages for interviews and a field trip. The interview topics included how their family groups are defined, what the name was of the group that used to live near the estuary, the status of who is allowed to perform songs and explain traditions, and what environmental changes they have seen at the estuary. Theories about the connection between oral history, oral tradition, and historical events, provided a framework to examine what they told me. To provide another view of this estuary, I created a Normalized Data Vegetation Index using satellite imagery from the years 2000 to 2018 that provides information about the mangrove vegetation. Instead of only being research subjects, the communities in which anthropologists engage can be considered partners. Since some of the Seri are trained paraecologists, this vegetation index will be presented to them to help in their environmental observations.

    In this study we assessed microglia morphology in male, pre-menopausal female, and post menopausal female mice (Male n = 5-6; Pre M n = 6; PM n = 8) following 8 hours of reperfusion, as a measurable response to injury. We hypothesized that because the size of infarct is decreased in pre-menopause female versus post-menopause female and male mice, that changes in microglia morphology post stroke will vary according to sex group. Using skeletal and fractal analysis, we found that ramified morphology is decreased in proximity to injury (endpoints/cell region main effect: F (3,68) = 20.71, p < 0.0001; process length/cell region main effect: F (3,68) = 11.63, p < 0.0001); however there are no differences among sex groups for the endpoints/cell variable (F (2,68) = 0.6, p < 0.55). In addition, fractal dimension decreased in proximity to the ischemic region with significant differences according to sex group (two-way ANOVA: region: F (3,57) = 36.80, p < 0.0001; sex group: F (2,19) = 7.5, p < 0.01). The focus of this study is on the basic discovery of microglia morphological response that can be used to develop treatments that have minimal variability among sex groups.
