Need for Aeromedical Evacuation High-Level Containment Transport Guidelines
Circumstances exist that call for the aeromedical evacuation high-level containment transport (AE-HLCT) of patients with highly hazardous communicable diseases. A small number of organizations maintain AE-HLCT capabilities, and little is publicly available regarding the practices. The time is ripe for the development of standards and consensus guidelines involving AE-HLCT
The effects of poetry-writing SANTEL on erotic body image in remission of cancer in women: a pilot study
International audienceAbstract Aim: Our pilot study aims to describe the effects ofa new specific and structured protocol focused on poetic/erotic writing (named SANTEL) on the (re)sexualization ofbody image in women, who have experienced cancer.Procedure: The protocol consists of four steps: to choose alist of erotic verses focused on the body parts, to fill a semistructuredpoetic text, to write sentences after target phraseson the body; and in the end, to write a free poem. Mrs V.suffered from breast cancer, and one breast was removed.She and her husband participated in this poetic writing protocol,separately. We analyzed the linguistic metaphors ofthe body by QSR Nvivo10 software.Results: Using this protocol, we showed discourse variationsof metaphors before and after the experience of writing.Patient V used âI feel like an alienâ as a starting metaphorto describe her cancer experience and after poetic writingsessions, she used other bodily metaphors like âMy body isa flowerâ and âMy sensual and white fleshâ.Conclusion: This poetic perspective promises a type ofâperceptive-literary surgeryâ, characterized by a sensualinvestment process after remission: a poetic reconstructionof erotic body image.Les effets d'un protocole d'Ă©criture poĂ©tique SANTEL sur l'image Ă©rotique du corps dans le traitement du cancer fĂ©minin : Ă©tude pilote The effects of poetry-writing SANTEL on erotic body image in remission of cancer in women: a pilot study A. Santarpia · J. TellĂšne · M. Carrier RĂ©sumĂ© Objectif : Cette Ă©tude pilote de type qualitative et exploratoire vise Ă dĂ©crire les effets d'un nouveau protocole d'Ă©criture poĂ©tico-Ă©rotique (nommĂ©e SANTEL) sur la rĂ©Ă©ro-tisation de l'image du corps chez une femme, ayant vĂ©cu un cancer. MatĂ©riel et mĂ©thodes : Il s'agit d'un protocole composĂ© de quatre Ă©tapes : une liste des phrases Ă caractĂšres poĂ©tiques et Ă©rotiques Ă choisir, un texte Ă trous Ă remplir, des amorces de phrases ciblĂ©es sur le corps et en fin un poĂšme libre. Madame V. a subi un cancer du sein nĂ©cessitant une ablation complĂšte. Madame V. et son conjoint exĂ©cutent le protocole d'Ă©criture sĂ©parĂ©ment. Nous montrons les variations discursives des mĂ©taphores utilisĂ©es avant et aprĂšs l'expĂ©rience de l'Ă©criture, Ă travers le logiciel d'analyse qualitative QSR NVivo10. RĂ©sultats : Madame V. passera de la mĂ©taphore initiale « je me sens une extraterrestre » vers la plus attĂ©nuĂ©e « Non. Je me dis qu'extraterrestre c'Ă©tait peut-ĂȘtre un peu Ă©norme ». En plus, elle utilisera de nouvelles mĂ©taphores linguistiques du corps pour raconter son image du corps telles que « ce corps de chair blanche » et « une fleur qui s'ouvre dĂ©licatement ». Conclusion : Cet exercice spĂ©cifique d'Ă©criture promet un type de « chirurgie perceptive-littĂ©raire » dans le processus d'investissement sensuel et affectif aprĂšs la rĂ©mission, une reconstruction perceptive et poĂ©tique de l'image Ă©rotique du corps.

miR-34a Silences c-SRC to Attenuate Tumor Growth in Triple-Negative Breast Cancer
Triple-negative breast cancer (TNBC) is an aggressive subtype with no clinically proven biologically targeted treatment options. The molecular heterogeneity of TNBC and lack of high frequency driver mutations other than TP53 have hindered the development of new and effective therapies that significantly improve patient outcomes. miRNAs, global regulators of survival and proliferation pathways important in tumor development and maintenance, are becoming promising therapeutic agents. We performed miRNA-profiling studies in different TNBC subtypes to identify miRNAs that significantly contribute to disease progression. We found that miR-34a was lost in TNBC, specifically within mesenchymal and mesenchymal stem cell-like subtypes, whereas expression of miR-34a targets was significantly enriched. Furthermore, restoration of miR-34a in cell lines representing these subtypes inhibited proliferation and invasion, activated senescence, and promoted sensitivity to dasatinib by targeting the proto-oncogene c-SRC. Notably, SRC depletion in TNBC cell lines phenocopied the effects of miR-34a reintroduction, whereas SRC overexpression rescued the antitumorigenic properties mediated by miR-34a. miR-34a levels also increased when cells were treated with c-SRC inhibitors, suggesting a negative feedback exists between miR-34a and c-SRC. Moreover, miR-34a administration significantly delayed tumor growth of subcutaneously and orthotopically implanted tumors in nude mice, and was accompanied by c-SRC downregulation. Finally, we found that miR-34a and SRC levels were inversely correlated in human tumor specimens. Together, our results demonstrate that miR-34a exerts potent antitumorigenic effects in vitro and in vivo and suggests that miR-34a replacement therapy, which is currently being tested in human clinical trials, represents a promising therapeutic strategy for TNBC.

Longitudinal Metagenomic Analysis of the Water and Soil from Gulf of Mexico Beaches Affected by the Deep Water Horizon Oil Spill
Estimates of 7x105 cubic meters of crude oil were released into the Gulf of Mexico as a consequence of the April 20th, 2010 Deep Water Horizon drilling rig explosion, leaving thousands of square miles of earth's surface covered in crude oil. Dispersants were used on large slicks and injected at the well head, resulting in oil being suspended throughout the water column. Starting in June 2010, oil reached hundreds of miles of Louisiana, Alabama, Mississippi, and Florida shoreline disturbing the ecological balance and economic stability of the region. While visible damages are evident in the wildlife populations and marine estuaries, the most significant affect may be on the most basic level of the ecosystems: the bacterial and plankton populations.We present results from high throughput DNA sequencing of close-to-shore water and beach soil samples before and during the appearance of oil in Louisiana and Mississippi. Sixteen samples were taken over a two month period at approximately two week intervals from Grand Isle, LA and Gulfport, MS and were sequenced using the Illumina GAIIx platform. Significant genomic-based population fluctuations were observed in the soil and water samples. These included large spikes in the human pathogen Vibrio cholera, a sharp increase in Rickettsiales sp., and decrease of Synechococus sp. in water samples. Analysis of the contiguous de-novo assembled DNAs (contigs) from the samples also suggested the loss of biodiversity in water samples by the time oil appeared at the shores in both locations. Our observations lead us to the conclusion that oil strongly influenced microbial population dynamics, had a striking impact on the phytoplankton and other flora present prior to the appearance of oil, and that the microbial community had not recovered to pre-spill conditions by the end of our observational period
MicroRNA-21 links epithelial-to-mesenchymal transition and inflammatory signals to confer resistance to neoadjuvant trastuzumab and chemotherapy in HER2-positive breast cancer patients
Patients with primary HER2-positive breast cancer benefit from HER2-targeted therapies. Nevertheless, a significant proportion of these patients die of disease progression due to mechanisms of drug resistance. MicroRNAs (miRNAs) are emerging as critical core regulators of drug resistance that act by modulating the epithelial- to-mesenchymal transition (EMT) and cancer-related immune responses. In this study, we investigated the association between the expression of a specific subset of 14 miRNAs involved in EMT processes and immune functions and the response to neoadjuvant trastuzumab and chemotherapy in 52 patients with HER2-overexpressing breast tumors. The expression of only a single miRNA, miR-21, was significantly associated with residual disease (p = 0.030) and increased after trastuzumab-chemotherapy (p = 0.012). A target prediction analysis coupled with in vitro and in vivo validations revealed that miR-21 levels inversely correlated with the expression of PTEN (rs = -0.502; p = 0.005) and PDCD4 (rs = -0.426; p = 0.019), which differentially influenced the drug sensitivity of HER2-positive breast cancer cells. However, PTEN expression was only marginally associated with residual disease. We further demonstrated that miR-21 was able to affect the response to both trastuzumab and chemotherapy, triggering an IL-6/STAT3/NF-\u3baB-mediated signaling loop and activating the PI3K pathway. Our findings support the ability of miR-21 signaling to sustain EMT and shape the tumor immune microenvironment in HER2-positive breast cancer. Collectively, these data provide a rationale for using miR-21 expression as a biomarker to select trastuzumab-chemotherapy-resistant HER2-positive breast cancer patients who may benefit from treatments containing PI3K inhibitors or immunomodulatory drugs
miRpower: a web-tool to validate survival-associated miRNAs utilizing expression data from 2178 breast cancer patients
PURPOSE: The proper validation of prognostic biomarkers is an important clinical issue in breast cancer research. MicroRNAs (miRNAs) have emerged as a new class of promising breast cancer biomarkers. In the present work, we developed an integrated online bioinformatic tool to validate the prognostic relevance of miRNAs in breast cancer. METHODS: A database was set up by searching the GEO, EGA, TCGA, and PubMed repositories to identify datasets with published miRNA expression and clinical data. Kaplan-Meier survival analysis was performed to validate the prognostic value of a set of 41 previously published survival-associated miRNAs. RESULTS: All together 2178 samples from four independent datasets were integrated into the system including the expression of 1052 distinct human miRNAs. In addition, the web-tool allows for the selection of patients, which can be filtered by receptors status, lymph node involvement, histological grade, and treatments. The complete analysis tool can be accessed online at: www.kmplot.com/mirpower . We used this tool to analyze a large number of deregulated miRNAs associated with breast cancer features and outcome, and confirmed the prognostic value of 26 miRNAs. A significant correlation in three out of four datasets was validated only for miR-29c and miR-101. CONCLUSIONS: In summary, we established an integrated platform capable to mine all available miRNA data to perform a survival analysis for the identification and validation of prognostic miRNA markers in breast cancer
