Reading, Trauma and Literary Caregiving 1914-1918: Helen Mary Gaskell and the War Library

This article is about the relationship between reading, trauma and responsive literary caregiving in Britain during the First World War. Its analysis of two little-known documents describing the history of the War Library, begun by Helen Mary Gaskell in 1914, exposes a gap in the scholarship of war-time reading; generates a new narrative of "how," "when," and "why" books went to war; and foregrounds gender in its analysis of the historiography. The Library of Congress's T. W. Koch discovered Gaskell's ground-breaking work in 1917 and reported its successes to the American Library Association. The British Times also covered Gaskell's library, yet researchers working on reading during the war have routinely neglected her distinct model and method, skewing the research base on war-time reading and its association with trauma and caregiving. In the article's second half, a literary case study of a popular war novel demonstrates the extent of the "bitter cry for books." The success of Gaskell's intervention is examined alongside H. G. Wells's representation of textual healing. Reading is shown to offer sick, traumatized and recovering combatants emotional and psychological caregiving in ways that she could not always have predicted and that are not visible in the literary/historical record

The 'new majority' and the academization of journalism

The academization of journalism is reliant on the development of the field founded in scholarship demonstrated through the publication of research in peer-reviewed specialist journals. Given the profile of journalism faculty, this means inducting practitioners into a culture of critical research. In Australia at least, this cohort of neophytes is predominantly comprised of middle-aged women who were surveyed about their personal attitudes to research. They were mostly open to the idea of becoming researchers but were inclined to proceed cautiously without necessarily severing their ties with practice. There was evidence to suggest that a generally positive orientation to research was not capitalized on and that they remained uncertain about the role of research. On the other hand, they appeared not to have adopted the orthodoxy of implacable opposition to scholarly inquiry. The change in gender composition in the academy may provide, contrary to historical, but more in line with contemporary, evidence, a renewed impetus to the project of academizing the field

Porphyromonas gingivalis Participates in Pathogenesis of Human Abdominal Aortic Aneurysm by Neutrophil Activation. Proof of Concept in Rats

International audienceBACKGROUND: Abdominal Aortic Aneurysms (AAAs) represent a particular form of atherothrombosis where neutrophil proteolytic activity plays a major role. We postulated that neutrophil recruitment and activation participating in AAA growth may originate in part from repeated episodes of periodontal bacteremia. METHODS AND FINDINGS: Our results show that neutrophil activation in human AAA was associated with Neutrophil Extracellular Trap (NET) formation in the IntraLuminal Thrombus, leading to the release of cell-free DNA. Human AAA samples were shown to contain bacterial DNA with high frequency (11/16), and in particular that of Porphyromonas gingivalis (Pg), the most prevalent pathogen involved in chronic periodontitis, a common form of periodontal disease. Both DNA reflecting the presence of NETs and antibodies to Pg were found to be increased in plasma of patients with AAA. Using a rat model of AAA, we demonstrated that repeated injection of Pg fostered aneurysm development, associated with pathological characteristics similar to those observed in humans, such as the persistence of a neutrophil-rich luminal thrombus, not observed in saline-injected rats in which a healing process was observed. CONCLUSIONS: Thus, the control of periodontal disease may represent a therapeutic target to limit human AAA progression

Immunization with FimA protects against Streptococcus parasanguis endocarditis in rats

FimA, a surface-associated protein of Streptococcus parasanguis, is associated with initial colonization of damaged heart tissue in an endocarditis model (D. Burnette-Curley, V. Wells, H. Viscount, C. Munro, J. Fenno, P. Fives-Taylor, and F. Macrina, Infect. Immun. 63:4669-4674, 1995). We have evaluated the efficacy of recombinant FimA as a vaccine in the rat model of endocarditis and investigated in vitro the mechanism for the protective role of immunization. FimA-immunized and nonimmunized control animals were catheterized to induce heart valve damage and infected intravenously with 10(7) CFU of wild-type S. parasanguis FW213 bacteria. The presence of bacteria associated with platelet-fibrin vegetations 24 h postchallenge was evaluated. Immunized rats were significantly less susceptible to endocarditis (2 cases among 34 animals) than the control group (21 cases among 33 animals) (P < 0.001). Incubation of S. parasanguis FW213 with rabbit anti-FimA immune serum decreased the mean percent adherence (0.34% of added cells) to platelet-fibrin matrix in vitro compared with that of preimmune normal serum (5.04% of added cells; P < 0.001). Adsorption of immune serum with FimA-positive S. parasanguis FW213 yielded antiserum that failed to block adherence to the platelet-fibrin matrix. We assessed the vaccine potential of FimA as a common immunogen able to provide cross-protection in streptococcal endocarditis by determining the occurrence and expression of fimA in the viridans group streptococci and enterococci. We detected the presence of fimA homologs by Southern hybridization and PCR amplification analyses and determined by immunoblotting the expression of FimA-like proteins among a variety of streptococci and enterococci that frequently cause endocarditis. Eighty-one percent (26 of 32) of streptococcal and enterococcal strains isolated from bacteremic patients expressed proteins that comigrated with FimA and were reactive with polyclonal anti-FimA serum. Streptococcal DNA from strains that were positive by Western blot (immunoblot) analysis hybridized to the full-length fimA probe. Our studies suggest that FimA immunization results in antibody-mediated inhibition of bacterial adherence, a critical early event in the pathogenesis of endocarditis. Our data demonstrate that a majority of streptococcal strains associated with endocarditis have genes that encode FimA-like proteins. Taken together, these results suggest that FimA is a promising candidate for an endocarditis vaccine
