Exploring the Feasibility of Text Messaging Intervention in Intimate Partner Violence

Introduction: Intimate Partner Violence (IPV) is defined as controlling, abusive, and aggressive behavior in a romantic relationship. Women between the ages 16 and 24 experience the highest rate of IPV. IPV costs US society at least $13.6 billion annually and is expected to rise to$15.6 billion by 2021. The purpose of this study is to explore the feasibility of Text Messaging Intervention\ud (TMI) in recognizing, responding and preventing IPV among college students. The research questions are: Will TMI 1) improve participant knowledge of warning signs of IPV? (Knowledge) and 2) improve participant confidence to intervene in IPV? (Confidence). Methods: A mixed methods design in data collection and data analysis was used. One-way ANOVA and Chi-square test were used to analyze quantitative data from the pre and post TMI survey. Results of the qualitative data analysis are included verbatim. Results: Results showed that knowledge level pre to post test increased from 2.00 ± 1.00 to 2.7 ± 0.48 (p < 0.001) and confidence level pre to post test increased from 2.89 ± 0.60 to 3.30 ± 0.68 (p < 0.001). Conclusions: Further research is needed in evaluating\ud the feasibility and effectiveness of IPV prevention programs that uses mobile devices to create the best optimal health outcomes

‘Savage times come again’ : Morel, Wells, and the African Soldier, c.1885-1920

The African soldier trained in western combat was a figure of fear and revulsion in the late nineteenth and early twentieth centuries. My article examines representations of African soldiers in nonfictional writings by E.D. Morel about the Congo Free State (1885-1908), the same author’s reportage on African troops in post-First World War Germany, and H.G. Wells’s speculative fiction When the Sleeper Wakes (1899, 1910). In each text racist and anti-colonialist discourses converge in representing the African soldier as the henchman of corrupt imperialism. His alleged propensity for taboo crimes of cannibalism and rape are conceived as threats to white safety and indeed supremacy. By tracing Wells’s connections to the Congo reform campaign and situating his novel between two phases of Morel’s writing career, I interpret When the Sleeper Wakes as neither simply a reflection of past events in Africa or as a prediction of future ones in Europe. It is rather a transcultural text which reveals the impact of European culture upon the ‘Congo atrocities’, and the inscription of this controversy upon European popular cultural forms and social debates

An Uncertain Dominion: Irish Psychiatry, Methadone, and the Treatment of Opiate Abuse

This paper investigates some productive ambiguities around the medical administration of methadone in the Republic of Ireland. The tensions surrounding methadone maintenance therapy (MMT) are outlined, as well as the sociohistorical context in which a serious heroin addiction problem in Ireland developed. Irish psychiatry intervened in this situation, during a time of institutional change, debates concerning the nature of addiction, moral panics concerning heroin addiction in Irish society and the recent boom in the Irish economy, known popularly as the Celtic Tiger. A particular history of this sort illuminates how technologies like MMT become cosmopolitan, settling into, while changing, local contexts

Flea Diversity as an Element for Persistence of Plague Bacteria in an East African Plague Focus

Plague is a flea-borne rodent-associated zoonotic disease that is caused by Yersinia pestis and characterized by long quiescent periods punctuated by rapidly spreading epidemics and epizootics. How plague bacteria persist during inter-epizootic periods is poorly understood, yet is important for predicting when and where epizootics are likely to occur and for designing interventions aimed at local elimination of the pathogen. Existing hypotheses of how Y. pestis is maintained within plague foci typically center on host abundance or diversity, but little attention has been paid to the importance of flea diversity in enzootic maintenance. Our study compares host and flea abundance and diversity along an elevation gradient that spans from low elevation sites outside of a plague focus in the West Nile region of Uganda (∼725–1160 m) to higher elevation sites within the focus (∼1380–1630 m). Based on a year of sampling, we showed that host abundance and diversity, as well as total flea abundance on hosts was similar between sites inside compared with outside the plague focus. By contrast, flea diversity was significantly higher inside the focus than outside. Our study highlights the importance of considering flea diversity in models of Y. pestis persistence

A Novel Core Genome-Encoded Superantigen Contributes to Lethality of Community-Associated MRSA Necrotizing Pneumonia

Bacterial superantigens (SAg) stimulate T-cell hyper-activation resulting in immune modulation and severe systemic illnesses such as Staphylococcus aureus toxic shock syndrome. However, all known S. aureus SAgs are encoded by mobile genetic elements and are made by only a proportion of strains. Here, we report the discovery of a novel SAg staphylococcal enterotoxin-like toxin X (SElX) encoded in the core genome of 95% of phylogenetically diverse S. aureus strains from human and animal infections, including the epidemic community-associated methicillin-resistant S. aureus (CA-MRSA) USA300 clone. SElX has a unique predicted structure characterized by a truncated SAg B-domain, but exhibits the characteristic biological activities of a SAg including Vβ-specific T-cell mitogenicity, pyrogenicity and endotoxin enhancement. In addition, SElX is expressed by clinical isolates in vitro, and during human, bovine, and ovine infections, consistent with a broad role in S. aureus infections of multiple host species. Phylogenetic analysis suggests that the selx gene was acquired horizontally by a progenitor of the S. aureus species, followed by allelic diversification by point mutation and assortative recombination resulting in at least 17 different alleles among the major pathogenic clones. Of note, SElX variants made by human- or ruminant-specific S. aureus clones demonstrated overlapping but distinct Vβ activation profiles for human and bovine lymphocytes, indicating functional diversification of SElX in different host species. Importantly, SElX made by CA-MRSA USA300 contributed to lethality in a rabbit model of necrotizing pneumonia revealing a novel virulence determinant of CA-MRSA disease pathogenesis. Taken together, we report the discovery and characterization of a unique core genome-encoded superantigen, providing new insights into the evolution of pathogenic S. aureus and the molecular basis for severe infections caused by the CA-MRSA USA300 epidemic clone

Mathematical models for immunology:current state of the art and future research directions

The advances in genetics and biochemistry that have taken place over the last 10 years led to significant advances in experimental and clinical immunology. In turn, this has led to the development of new mathematical models to investigate qualitatively and quantitatively various open questions in immunology. In this study we present a review of some research areas in mathematical immunology that evolved over the last 10 years. To this end, we take a step-by-step approach in discussing a range of models derived to study the dynamics of both the innate and immune responses at the molecular, cellular and tissue scales. To emphasise the use of mathematics in modelling in this area, we also review some of the mathematical tools used to investigate these models. Finally, we discuss some future trends in both experimental immunology and mathematical immunology for the upcoming years
