Conditional Risk for PTSD Traumatically Injured Latinx Sample: Cultural X Biological Model

Posttraumatic stress disorder (PTSD) is a debilitating disorder that develops in some people following a traumatic event. Latinx communities in the U.S. are at greater risk of developing this disorder and experiencing more severe and chronic symptomology. This population has also been found to experience greater levels of dissociative experiences – possibly explaining the increased conditional risk for PTSD in this ethnic group. It remains unclear what may be connecting the experience of peritraumatic dissociation to heightened PTSD risk. The current study sought to address this gap in the literature by examining peritraumatic dissociation and the interplay between sociocultural and biological factors acutely following a traumatic injury. A sample of 52 Latinx, traumatically injured patients were recruited. In the acute aftermath of the trauma, participants provided blood samples, HRV measurements, and completed self-report measures assessing peritraumatic dissociation, PTSD symptoms, acculturative stress, fatalism, and familism. Moderated-mediational analyses were conducted to examine the ability of biological variables to mediate the relationship between peritraumatic dissociation and PTSD symptoms, while also considering the moderating influence of each cultural factor on the biological variable – PTSD symptoms pathway. After adjusting for psychiatric history and time of cortisol collection, results were non-significant. However, post-hoc analyses revealed notable findings regarding peritraumatic dissociation and acculturative stress. Results extend previous research by contributing to the understanding of unique cultural experiences and how this may be underlying greater risk for PTSD in Latinx populations. The current study is the first to examine risk for PTSD from an integrative perspective in a Latinx sample

Relations of Discriminatory Experiences and Marianismo Beleifs with PTSD Symptoms in Latinx Women

Research examining the discriminatory experiences of Latinx women in minimal. The present study examined if various forms of discrimination predicted mental health symptoms in a sample of Latinx women, with the conceptualization of chronic discrimination as a possible form of trauma. There is evidence showing that Latinx individuals are at risk to develop posttraumatic stress disorder at higher rates than their non-Hispanic White counterparts, with many studies pointing to the experiences of racial/ethnic discrimination as a significant contributor (Kaczkurkin, Asnaani, Hall-Clark, Peterson, Yarvis, & Foa, 2016). Given the multiple forms of discrimination that women of color experience, ethnic discrimination, sexism, and sexual objectification were assessed as forms of discrimination. These variables were examined for their relationship to psychological distress and PTSD symptoms. Marianismo, traditional Latinx cultural gender roles, was examined as a moderator for discrimination and mental health symptoms. A community sample of Latinx women (N = 132) were recruited to complete self-report surveys. Ethnic discrimination was found to be a robust predictor of both PTSD symptoms and psychological distress. Sexual objectification predicted PTSD symptoms above and beyond other variables, while sexism was found to predict psychological distress above and beyond other variables in a series of hierarchical regressions. Marianismo was not a significant moderator for discrimination and mental health symptoms. This study aimed to expand on the intersectional experiences of Latinx women and the relationship to mental health symptoms. Support was found for the relationship between discriminatory experiences and symptoms of PTSD as well as psychological distress

Intersectionality Research Within Latinx Mental Health: Conceptual and Methodological Considerations

Intersectionality considers the meaning and consequences associated with multiple identities along interlocking systems of disadvantage and inequality (Cole, 2009; Crenshaw, 1991). In recent years, there has been increasing attention on examining the mental health outcomes associated with membership in multiple marginalized groups. Unfortunately, intersectionality research examining the unique experiences of Latinx groups remains scarce. The current article reviews theoretical and methodological considerations regarding intersectionality research within Latinx mental health. From a theoretical perspective, intersectionality brings a series of questions regarding the epistemological approaches to studying psychological phenomena. This, in turn, influ- ences the methodological strategies used to examine these processes. The discussion advances the ongoing discourse regarding the benefits and limitations of integrating intersectionality within research that provides further insight into our Latinx communities

Voluntary Green Power Market Forecast Through 2015

Voluntary markets for renewable energy in which consumers purchase renewable energy from their electricity providers or from renewable energy certificate (REC) marketers have existed for more than a decade. Going forward, various factors will influence the development of these markets, including potential climate policies, state and federal renewable portfolio standards (RPS), renewable energy prices, the level of consumer interest in purchasing green power, and the interest on the part of utilities in offering new green options and in continuing to promote existing programs. This report presents estimates of voluntary market demand for renewable energy or green power through 2015. The forecast relies on historical data, including market sector sizes and growth rates, to inform our assumptions. Though we adjusted growth rates as discussed in the report, they remain the starting point for our analysis. Because of the different factors that affect utility programs, REC markets, and competitive electric markets, separate assumptions and methods are used to project demand for each submarket

Examination of the Regional Supply and Demand Balance for Renewable Electricity in the United States Through 2015

This report examines the balance between the demand and supply of new renewable electricity in the United States on a regional basis through 2015. It expands on a 2007 NREL study (Swezey et al. 2007) that assessed the supplynational basis. As with the earlier study, this analysis relies on estimates of renewable energy supplies compared to demand for renewable energy generation needed to meet existing state renewable portfolio standard (RPS) policies in 28 states, as well as demand by consumers who voluntarily purchase renewable energy. However, it does not address demand by utilities that may procure cost-effective renewables through an integrated resource planning process or otherwise. The analysis examines two supply scenarios: 1) a business as usual (BAU) scenario based on current growth rates in renewable energy supply in each region and 2) a market-based scenario that differs only in an assumed higher overall level of wind energy development nationally (based on estimates from BTM Consult and referred to as “high wind case”). Because the BTM Consult (2008) projections are only available nationally, and are not broken out regionally, this analysis uses results from a recent study by DOE (DOE 2008) that presents a scenario of 20% wind energy penetration by 2030 to apportion the wind energy capacity by region

Examination of the Regional Supply and Demand Balance for Renewable Electricity in the United States Through 2015: Projecting From 2009 Through 2015 (Revised)

Use of Nanopore Sequencing to Characterise the Genomic Architecture of Mobile Genetic Elements Encoding bla CTX-M-15 in Escherichia coli Causing Travellers' Diarrhoea

Increasing levels of antimicrobial resistance (AMR) have been documented in Escherichia coli causing travellers’ diarrhoea, particularly to the third-generation cephalosporins. Diarrhoeagenic E. coli (DEC) can act as a reservoir for the exchange of AMR genes between bacteria residing in the human gut, enabling them to survive and flourish through the selective pressures of antibiotic treatments. Using Oxford Nanopore Technology (ONT), we sequenced eight isolates of DEC from four patients’ specimens who had all recently returned to the United Kingdome from Pakistan. Sequencing yielded two DEC harbouring bla(CTX-M-15) per patient, all with different sequence types (ST) and belonging to five different pathotypes. The study aimed to determine whether bla(CTX-M-15) was located on the chromosome or plasmid and to characterise the drug-resistant regions to better understand the mechanisms of onward transmission of AMR determinants. Patients A and C both had one isolate where bla(CTX-M-15) was located on the plasmid (899037 & 623213, respectively) and one chromosomally encoded (899091 & 623214, respectively). In patient B, bla(CTX-M-15) was plasmid-encoded in both DEC isolates (786605 & 7883090), whereas in patient D, bla(CTX-M-15) was located on the chromosome in both DEC isolates (542093 & 542099). The two bla(CTX-M-15)-encoding plasmids associated with patient B were different although the bla(CTX-M-15)-encoding plasmid isolated from 788309 (IncFIB) exhibited high nucleotide similarity to the bla(CTX-M-15)-encoding plasmid isolated from 899037 (patient A). In the four isolates where bla(CTX-M-15) was chromosomally encoded, two isolates (899091 & 542099) shared the same insertion site. The bla(CTX-M-15) insertion site in isolate 623214 was described previously, whereas that of isolate 542093 was unique to this study. Analysis of Nanopore sequencing data enables us to characterise the genomic architecture of mobile genetic elements encoding AMR determinants. These data may contribute to a better understanding of persistence and onward transmission of AMR determinants in multidrug-resistant (MDR) E. coli causing gastrointestinal and extra-intestinal infections
