The Movement between: Dance improvisation, witnessing and participatory performance.
This was a practice-based project which extended the possibilities for dance improvisation in performance. The project engaged questions about how live performance is constituted, about what the roles of the dancer and audience might entail, and about how a community of common experience can develop through a responsive exchange between its participants
Identifying which septic patients have increased mortality risk using severity scores:a cohort study
Background: Early aggressive therapy can reduce the mortality associated with severe sepsis but this relies on prompt recognition, which is hindered by variation among published severity criteria. Our aim was to test the performance of different severity scores in predicting mortality among a cohort of hospital inpatients with sepsis. Methods: We anonymously linked routine outcome data to a cohort of prospectively identified adult hospital inpatients with sepsis, and used logistic regression to identify associations between mortality and demographic variables, clinical factors including blood culture results, and six sets of severity criteria. We calculated performance characteristics, including area under receiver operating characteristic curves (AUROC), of each set of severity criteria in predicting mortality. Results: Overall mortality was 19.4% (124/640) at 30 days after sepsis onset. In adjusted analysis, older age (odds ratio 5.79 (95% CI 2.87-11.70) for ≥80y versus <60y), having been admitted as an emergency (OR 3.91 (1.31-11.70) versus electively), and longer inpatient stay prior to sepsis onset (OR 2.90 (1.41-5.94) for >21d versus <4d), were associated with increased 30 day mortality. Being in a surgical or orthopaedic, versus medical, ward was associated with lower mortality (OR 0.47 (0.27-0.81) and 0.26 (0.11-0.63), respectively). Blood culture results (positive vs. negative) were not significantly association with mortality. All severity scores predicted mortality but performance varied. The CURB65 community-acquired pneumonia severity score had the best performance characteristics (sensitivity 81%, specificity 52%, positive predictive value 29%, negative predictive value 92%, for 30 day mortality), including having the largest AUROC curve (0.72, 95% CI 0.67-0.77). Conclusions: The CURB65 pneumonia severity score outperformed five other severity scores in predicting risk of death among a cohort of hospital inpatients with sepsis. The utility of the CURB65 score for risk-stratifying patients with sepsis in clinical practice will depend on replicating these findings in a validation cohort including patients with sepsis on admission to hospital
The Dancing Between Two Worlds Project: Background, Methodology and Learning to Approach Community in Place
This article recounts the history to date of the Dancing Between Two Worlds (DBTW) project, which was initiated by a team of artist-scholars at Deakin University in 2018. DBTWâs brief was to engage the Indian community living in the western fringes of Melbourne in a project on civic belonging, cross-cultural artistic identity, and the performance of outer-suburban Indian diaspora. Working with the creative and community energies that are activated at the intersection of the creative arts and demographically inflected place, the Deakin researchers collaborated with local artists with an Indian background on a major performance in late 2019: Dancing Between 2 Worlds. This performance came out of a series of creative exchanges in community venues and public spaces in the City of Wyndham Local Government Area (LGA), whereby the Deakin team offered contemporary âWesternâ creative approaches and the Indian artists shared their traditional artistic practicesâamidst discussions about place, belonging and identity. This process was supplemented by interviews with some of the participants. Our article contextualizes the DBTW project through a summary of two previous, similar Deakin enterprises; looks at the significant methodological issues linked to the project; describes the performance of late 2019; and uses project images and other figures to relate its story. We also take this opportunity to consider the nexus of a practice-led research project with community: that is, the relationships and liaison between institution (Deakin University), local government, participants, and placeâover time. The article concludes by digging in to the discursive tension between the terms âprojectâ and âgroupâ and (provisionally) resolves this tension in favour of the ongoing use of the word âprojectâ for DBTW. In this way, we add to the ideas on the ârhetoric of projectsâ originally expressed by Paul Carter in Material Thinking. The latter section of the article draws on interview material to give voice to the local Indian community members and artists around the developing thematic preoccupations of DBTW, comprising civic belonging, cross-cultural artistic identity, and the performance of Indian diaspora in outer suburban Melbourne. The focus of this article, however, concerns the learning curve at Deakin University that indexes the development of its approach to community in place
Evaluation of the activity of CYP2C19 in Gujrati and Marwadi subjects living in Mumbai (Bombay)
BACKGROUND: Inherited differences in the metabolism and disposition of drugs, and genetic polymorphisms in the targets of drug therapy (e.g., receptors), can greatly influence efficacy and toxicity of medications. Marked interethnic differences in CYP2C19 (a member of the cytochrome P-450 enzyme superfamily catalyzing phase I drug metabolism) which affects the metabolism of a number of clinically important drugs have been documented. The present study evaluated the activity of CYP2C19 in normal, healthy Gujrati and Marwadi subjects by phenotyping (a western Indian population). METHODS: All subjects received 20 mg of omeprazole, which was followed by blood collection at 3 hrs to estimate the metabolic ratio of omeprazole to 5-hydroxyomeprazole. The analysis was done by HPLC. RESULTS: It was seen that 10.36% of this population were poor metabolizers(PM) whereas 89.63% were extensive metabolizers(EM). CONCLUSION: A genotyping evaluation would better help in identifying population specific genotypes and thus help individualize drug therapy
First-in-Human Study of AT13148, a Dual ROCK-AKT Inhibitor in Patients with Solid Tumors
Purpose: AT13148 is an oral AGC kinase inhibitor, which potently inhibits ROCK and AKT kinases. In preclinical models, AT13148 has been shown to have antimetastatic and antiproliferative activity. Patients and Methods: The trial followed a rolling six design during dose escalation. An intrapatient dose escalation arm to evaluate tolerability and a biopsy cohort to study pharmacodynamic effects were later added. AT13148 was administered orally three days a week (MonâWedâFri) in 28-day cycles. Pharmacokinetic profiles were assessed using mass spectrometry and pharmacodynamic studies included quantifying p-GSK3β levels in platelet-rich plasma (PRP) and p-cofilin and p-MLC2 levels in tumor biopsies. Results: Fifty-one patients were treated on study. The safety of 5â300 mg of AT13148 was studied. Further, the doses of 120â180â240 mg were studied in an intrapatient dose escalation cohort. The dose-limiting toxicities included hypotension (300 mg), pneumonitis, and elevated liver enzymes (240 mg), and skin rash (180 mg). The most common side effects were fatigue, nausea, headaches, and hypotension. On the basis of tolerability, 180 mg was considered the maximally tolerated dose. At 180 mg, mean Cmax and AUC were 400 nmol/L and 13,000 nmol/L/hour, respectively. At 180 mg, âĽ50% reduction of p-cofilin was observed in 3 of 8 posttreatment biopsies.
Conclusions: AT13148 was the first dual potent ROCK-AKT inhibitor to be investigated for the treatment of solid tumors. The narrow therapeutic index and the pharmacokinetic profile led to recommend not developing this compound further. There are significant lessons learned in designing and testing agents that simultaneously inhibit multiple kinases including AGC kinases in cancer
How 'dynasty' became a modern global concept : intellectual histories of sovereignty and property
The modern concept of âdynastyâ is a politically-motivated modern intellectual invention. For many advocates of a strong sovereign nation-state across the nineteenth and early twentieth century, in France, Germany, and Japan, the concept helped in visualizing the nation-state as a primordial entity sealed by the continuity of birth and blood, indeed by the perpetuity of sovereignty. Hegelâs references to âdynastyâ, read with Marxâs critique, further show how âdynastyâ encoded the intersection of sovereignty and big property, indeed the coming into self-consciousness of their mutual identification-in-difference in the age of capitalism. Imaginaries about âdynastyâ also connected national sovereignty with patriarchal authority. European colonialism helped globalize the concept in the non-European world; British India offers an exemplar of ensuing debates. The globalization of the abstraction of âdynastyâ was ultimately bound to the globalization of capitalist-colonial infrastructures of production, circulation, violence, and exploitation. Simultaneously, colonized actors, like Indian peasant/âtribalâ populations, brought to play alternate precolonial Indian-origin concepts of collective regality, expressed through terms like ârajavamshiâ and âKshatriyaâ. These concepts nourished new forms of democracy in modern India. Global intellectual histories can thus expand political thought today by provincializing and deconstructing Eurocentric political vocabularies and by recuperating subaltern models of collective and polyarchic power.PostprintPeer reviewe
Protocol for investigating genetic determinants of posttraumatic stress disorder in women from the Nurses' Health Study II
<p>Abstract</p> <p>Background</p> <p>One in nine American women will meet criteria for the diagnosis of posttraumatic stress disorder (PTSD) in their lifetime. Although twin studies suggest genetic influences account for substantial variance in PTSD risk, little progress has been made in identifying variants in specific genes that influence liability to this common, debilitating disorder.</p> <p>Methods and design</p> <p>We are using the unique resource of the Nurses Health Study II, a prospective epidemiologic cohort of 68,518 women, to conduct what promises to be the largest candidate gene association study of PTSD to date. The entire cohort will be screened for trauma exposure and PTSD; 3,000 women will be selected for PTSD diagnostic interviews based on the screening data. Our nested case-control study will genotype1000 women who developed PTSD following a history of trauma exposure; 1000 controls will be selected from women who experienced similar traumas but did not develop PTSD.</p> <p>The primary aim of this study is to detect genetic variants that predict the development of PTSD following trauma. We posit inherited vulnerability to PTSD is mediated by genetic variation in three specific neurobiological systems whose alterations are implicated in PTSD etiology: the hypothalamic-pituitary-adrenal axis, the locus coeruleus/noradrenergic system, and the limbic-frontal neuro-circuitry of fear. The secondary, exploratory aim of this study is to dissect genetic influences on PTSD in the broader genetic and environmental context for the candidate genes that show significant association with PTSD in detection analyses. This will involve: conducting conditional tests to identify the causal genetic variant among multiple correlated signals; testing whether the effect of PTSD genetic risk variants is moderated by age of first trauma, trauma type, and trauma severity; and exploring gene-gene interactions using a novel gene-based statistical approach.</p> <p>Discussion</p> <p>Identification of liability genes for PTSD would represent a major advance in understanding the pathophysiology of the disorder. Such understanding could advance the development of new pharmacological agents for PTSD treatment and prevention. Moreover, the addition of PTSD assessment data will make the NHSII cohort an unparalleled resource for future genetic studies of PTSD as well as provide the unique opportunity for the prospective examination of PTSD-disease associations.</p
