Words and Silences : The journal of the International Oral History Association

Words and Silences is the official on-line journal of the International Oral History Association. It is an internationally peer reviewed, high quality forum for oral historians from a wide range of disciplines and a means for the professional community to share projects and current trends of oral history from around the world. We are extremely pleased to release the first online issue of Word &Silences. This e-journal is the result of long standing discussion and debate about the best way to publish a quality bilingual oral history journal (including a blind peer reviewed section) as a viable solution to mounting difficulties associated with publishing in print. We have discovered that an online version is also not without its challenges and requires tremendous labor intensive dedication. We strongly encourage members to assist us with small review process tasks in the future, so that we can ensure the sustainability of an annual W&S publication for our members and beyond.

Disaster strikes, then what? Using evaluation in narrative driven (oral history & digital storytelling) community-based projects

In 2011 Queensland suffered both floods and cyclones, leaving residents without homes and their communities in ruins (2011). This paper presents how researchers from QUT, who are also members of the Oral History Association of Australia (OHAA) Queensland’s chapter, are using oral history, photographs, videography and digital storytelling to help heal and empower rural communities around the state and how evaluation has become a key element of our research. QUT researchers ran storytelling workshops in the capital city of Brisbane i early 2011, after the city suffered sever flooding. Cyclone Yasi then struck the town of Cardwell (in February 2011) destroying their historical museum and recording equipment. We delivered an 'emergency workshop', offering participants hands on use of the equipment, ethical and interviewing theory, so that the community could start to build a new collection. We included oral history workshops as well as sessions on how best to use a video camera, digital camera and creative writing sessions, so the community would also know how to make 'products' or exhibition pieces out of the interviews they were recording. We returned six months later to conduct follow-up workshops and the material produced by and with the community had been amazing. More funding has now been secured to replicate audio/visual/writing workshops in other remote rural Queensland communities including Townsville, Mackay and Cunnamulla and Toowoomba in 2012, highlighting the need for a multi media approach, to leverage the most out of OH interviews as a mechanism to restore and promote community resilience and pride.

In the Wake of Cyclone Yasi : Facilitation and Evaluation in Community Narrative-Driven Projects

On 3 February 2011, Cyclone Yasi struck the coast of North Queensland, causing widespread damage. The cyclone destroyed the small coastal town of Cardwell, about 165 kilometres north of Townsville, Queensland. This chapter serves as a case study of a collaborative outreach project mobilised in response to this disaster in North Queensland. A public history research team, consisting of practitioners from the Queensland University of Technology’s Creative Industries Faculty, with the support of the Oral History Association of Australia, Queensland branch, partnered with the Cardwell and District Historical Society to support the society to collect community narratives in the wake of Cyclone Yasi.

Yasi : Digital stories and oral histories collection

"The second of the Oral History Workshops conducted by Associate Professor Helen Klaebe and the Oral History team from the Queensland University of Technology in Brisbane, was conducted in El Arish on the last weekend in September 2011. The first workshop was held in Cardwell in March 2011. Historical Society members and other researchers from both the Cardwell and El Arish areas combined to organise and fund the workshops, which have produced a growing collection of recordings of personal stories from people with a wide variety of experiences during and after cyclone Yasi. Aside from being productive in documenting history, the workshops have offered a greatly appreciated educational opportunity for many people, most of whom have never before had access to such benefits. Not only were they able to learn history gathering methodologies and the relevant technical skills, but they also gained new experience in the use of computers to apply these skills. These far northern oral history workshops took the form of a shortened version of the 5 series workshops being presented at QUT in Brisbane this year. The agenda was aligned to the wishes and requirements of the participants who attended from the Cassowary Coast and Tableland regions."

Human milk xanthine oxidase and neonatal salivary nucleotide precursors generate hydrogen peroxide; a novel pathway with potential role in regulating oral microflora

Background: Xanthine oxidase (XO) is a complex molybdeno-flavoprotein occurring with high activity in the milk fat globule membrane (MFGM) in all mammalian milk and is involved in the final stage of degradation of purine nucleotides. It catalyzes the sequential oxidation of hypoxanthine to xanthine and uric acid, accompanied by production of hydrogen peroxide and superoxide anion. Human saliva has been extensively described for its composition of proteins, electrolytes, cortisol, melatonin and some metabolites such as amino acids, but little is known about nucleotide metabolites. Method: Saliva was collected with swabs from babies; at full-term 1-4 days, 6-weeks, 6-months and 12-months. Unstimulated fasting (morning) saliva samples were collected directly from 77 adults. Breast milk was collected from 24 new mothers. Saliva was extracted from swabs and ultra-filtered. Nucleotide metabolites were analyzed by RP-HPLC with UV-photodiode array and ESI-MS/MS. XO activity was measured as peroxide production from hypoxanthine. Bacterial inhibition over time was assessed using CFU/mL or OD. Results: Median concentrations (μmol/L) of salivary nucleobases and nucleosides for neonates/6-weeks/6-months/12-months/adult respectively were: uracil 5.3/0.8/1.4/0.7/0.8, hypoxanthine 27/7.0/1.1/0.8/2.0, xanthine 19/7.0/2.0/2.0/2.0, adenosine 12/7.0/0.9/0.8/0.1, inosine 11/5.0/0.3/0.4/0.2, guanosine 7.0/6.0/0.5/0.4/0.1, uridine 12/0.8/0.3/0.9/0.4. Deoxynucleosides and dihydropyrimidines concentrations were essentially negligible. XO activity (Vmax:mean ± SD) in breast milk was 8.9 ± 6.2 μmol/min/L and endogenous peroxide was 27 ± 12 μmol/L; mixing breast milk with neonate saliva generated ~40 μmol/L peroxide,which inhibited Staphylococcus aureus. Conclusions: Salivary metabolites, particularly xanthine/hypoxanthine, are high in neonates, transitioning to low adult levels between 6-weeks to 6-months (p < 0.001). Peroxide occurs in breast milk and is boosted during suckling as an antibacterial system.

When Can Oral Health Education Begin? Relative effectiveness of three oral health education strategies starting pre-partum

Objective: To test the impact of oral health education provided to pregnant mothers on subsequent practices within the infant’s family. Research design: A quasi-experimental intervention trial comparing the effectiveness of ‘usual care’ to one, or both, of two oral health education resources: a ‘sample bag’ of information and oral health care products; and/or a nine-minute “Healthy Teeth for Life” video on postnatal oral health issues. Participants: Women attending the midwife clinic at approximately 30 weeks gestation were recruited (n=611) in a public hospital providing free maternity services. Results and Conclusions: Four months after the birth of their infant, relative to the usual care condition, each of the oral health education interventions had independent or combined positive impacts on mother’s knowledge of oral health practices. However young, single, health care card-holder or unemployed mothers were less likely to apply healthy behaviours or to improve knowledge of healthy choices, as a result of these interventions. The video intervention provided the strongest and most consistent positive impact on mothers’ general and infant oral health knowledge. While mothers indicated that the later stage of pregnancy was a good time to receive oral health education, many suggested that this should also be provided after birth at a time when teeth were a priority issue, such as when “baby teeth” start to erupt.

The artful life story : the oral history interview as fiction

This practice-led PhD project consists of two parts. The first is an exegesis documenting how a fiction writer can enter a dialogue with the oral history project in Australia. I identify two philosophical mandates of the oral history project in Australia that have shaped my creative practice: an emphasis on the analysis of the interviewee’s subjective experience as a means of understanding the past, and the desire to engage a wide audience in order to promote empathy towards the subject. The discussion around fiction in the oral history project is in its infancy. In order to deepen the debate, I draw on the more mature discussion in ethnographic fiction. I rely on literary theorists Steven Greenblatt, Dorrit Cohn and Gerard Genette to develop a clear understanding of the distinct narrative qualities of fiction, in order to explore how fiction can re-present and explore an interviewee’s subjective experience, and engage a wide readership. I document my own methodology for producing a work of fiction that is enriched by oral history methodology and theory, and responds to the mandates of the project. I demonstrate the means by which fiction and the oral history project can enter a dialogue in the truest sense of the word: a two-way conversation that enriches and augments practice in both fields. The second part of the PhD is a novel, set in Brisbane and based on oral history interviews and archival material I gathered over the course of the project. The novel centres on Brisbane artist Evelyn, who has been given an impossible task: a derelict old house is about to be demolished, and she must capture its history in a sculpture that will be built on the site. Evelyn struggles to come up with ideas and create the sculpture, realising that she has no way to discover who inhabited the house. What follows is a series of stories, each set in a different era in Brisbane’s history, which take the reader backwards through the house’s history. Hidden Objects is a novel about the impossibility of grasping the past and the powerful pull of storytelling. The novel is an experiment in a hybrid form and is accompanied by an appendix that identifies the historically accurate sources informing the fiction. The decisions about the aesthetics of the novel were a direct result of my engagement with the mandates of the oral history project in Australia. The novel was shortlisted in the 2012 Queensland Literary Awards, unpublished manuscript category.

Does preoperative oral carbohydrate reduce hospital stay?

Background Carbohydrate-rich fluids are used to improve postoperative recovery but the effectiveness of the product for reducing length of hospital stay is uncertain. Objective To assess the effectiveness of preoperative loading with carbohydrates on postoperative outcomes. Participants Forty six patients booked for elective colorectal surgery. Methods Participants were allocated to a Carbohydrate-rich fluid group or Usual Care group during their pre-admission clinic visit. The primary outcome was ‘Time to readiness for discharge’. Results Patients in the control group spent on average 4.3 days (95% confidence interval 3.2 to 5.7) and the Carbohydrate-rich fluid group spent 4.1 days (95% confidence interval 3.2 to 5.4) until the primary outcome was met (p=0.824). Conclusion The safety of preoperative high carbohydrate fluids is supported but we were unable to confirm or refute the benefit of CHO for shorter hospital stay following elective colorectal surgery.

Simultaneous determination by UPLC-ESI-MS of scoparone, capillarisin, rhein, and emodin in rat urine after oral administration of Yin Chen Hao Tang preparation

A simple, sensitive, and validated method was developed for simultaneous determination of scoparone, capillarisin, rhein, and emodin in rat urine by ultra-performance liquid chromatography/electrospray ionization quadruple time-of-flight mass spectrometry (UPLC-MS). The urinary samples were analyzed on an Acquity UPLC BEH C18 1.7 microm 2.1x50 mm column. Scoparone, capillarisin, rhein, and emodin in rat urine were simultaneously analyzed with good separation. The lower limits of detection were 6.0, 9.0, 7.0, and 3.0 ng/mL, and the lower limits of quantification were 20.0, 33.0, 24.0, and 12.0 ng/mL for scoparone, capillarisin, rhein, and emodin, respectively. The intra- and inter-day precisions (RSD) were less than 9%. The intra- and inter-accuracies were found to be in the range of 94.14-104.54% for scoparone, 101.72-107.34% for capillarisin, 95.24-103.59% for rhein, and 101.32-107.82% for emodin at three concentration levels. The absolute recoveries for scoparone, capillarisin, rhein, and emodin were not less than 77.0%. The developed method has been applied to determine scoparone, capillarisin, rhein, and emodin in rat urine after oral administration of Yin Chen Hao Tang preparation, a traditional Chinese medicine formulation widely used in China for treatment of jaundice and liver disorders.

Pharmacokinetics of isofraxidin in rat plasma after oral administration of the extract of acanthopanax senticosus using HPLC with solid phase extraction method

High-performance liquid chromatography coupled with solid phase extraction method was developed for determination of isofraxidin in rat plasma after oral administration of Acanthopanax senticosus extract (ASE), and pharmacokinetic parameters of isofraxidin either in ASE or pure compound were measured. The HPLC analysis was performed on a Dikma Diamonsil RP(18) column (4.6 mm x 150 mm, 5 microm) with the isocratic elution of solvent A (acetonitrile) and solvent B (0.1% aqueous phosphoric acid, v/v) (A : B = 22 : 78) and the detection wavelength was set at 343 nm. The calibration curve was linear over the range of 0.156-15.625 microg/ml. The limit of detection was 60 ng/ml. The intra-day precision was 5.8%, and the inter-day precision was 6.0%. The recovery was 87.30+/-1.73%. When the dosage of ASE is equal to pure compound caculated by the amount of isofraxidin, it has been found to have two maximum concentrations in plasma while the pure compound only showed one peak in the plasma concentration-time curve. The determined content of isofraxidin in plasma after oral administration of ASE is the total contents of free isofraxidin and its precursors in ASE in vitro. The pharmacokinetic characteristics of ASE showed the priority of the extract and the properities of traditional Chinese medicine.

Analysis of the constituents in the rat plasma after oral administration of Yin Chen Hao Tang by UPLC/Q-TOF-MS/MS

A UPLC/Q-TOF-MS/MS method for analyzing the constituents in rat plasma after oral administration of Yin Chen Hao Tang (YCHT), a traditional Chinese medical formula, has been established. The UPLC/MS fingerprints of the samples were established first in vitro and in vivo, with 45 compounds in YCHT and 21 compounds in rat plasma after oral administration of YCHT were detected. Of the 45 detected compounds in vitro, 30 were identified, and all of the 21 compounds detected in rat plasma were identified either by comparing the retention time and mass spectrometry data with that of reference compounds or by mass spectrometry analysis and retrieving the reference literatures. Of the identified 21 compounds in rat plasma, 19 were the original form of compounds absorbed from the 45 detected compounds in vitro, 2 were the metabolites of the compounds existed in YCHT. It is concluded that a rapid and validated method has been developed based on UPLC-MS/MS, which shows high sensitivity and resolution that is more suitable for identifying the bioactive constituents in plasma after oral administration of Chinese herbal medicines, and provides helpful chemical information for further pharmacology and active mechanism research on the Chinese medical formula.

Pharmacokinetics of cimifugin in rat plasma after oral administration of the extract of Saposhnikovia divaricatae root : Determination of cimifugin by high performance liquid chromatography coupled with solid phase extraction

High performance liquid chromatography (HPLC) coupled with the solid phase extraction method was developed for determining cimifugin (a coumarin derivative; one of Saposhnikovia divaricatae's constituents) in rat plasma after oral administration of Saposhnikovia divaricatae extract (SDE), and the pharmacokinetics of cimifugin either in SDE or as a single compound was investigated. The HPLC analysis was performed on a commercially available column (4.6 mm x 200 mm, 5 pm) with the isocratic elution of solvent A (Methanol) and solvent B (Water) (A:B=60:40) and the detection wavelength was set at 250 nm. The calibration curve was linear over the range of 0.100-10.040 microg/mL. The limit of detection was 30 ng/mL. At the rat plasma concentrations of 0.402, 4.016, 10.040 microg/mL, the intra-day precision was 6.21%, 3.98%, and 2.23%; the inter-day precision was 7.59%, 4.26%, and 2.09%, respectively. The absolute recovery was 76.58%, 76.61%, and 77.67%, respectively. When the dosage of SDE was equal to the pure compound calculated by the amount of cimifugin, it was found to have two maximum peaks while the pure compound only showed one peak in the plasma concentration-time curve. The pharmacokinetic characteristics of SDE showed the superiority of the extract and the properties of traditional Chinese medicine.

Women from refugee backgrounds and their experiences of attending a specialist antenatal clinic : narratives from an Australian setting

Problem: In response to an identified need, a specialist antenatal clinic for women from refugee backgrounds was introduced in 2008, with an evaluation planned and completed in 2010. Question: Can maternity care experiences for women from refugee backgrounds, attending a specialist antenatal clinic in a tertiary Australian public hospital, be improved? Methods: The evaluation employed mixed methods, generating qualitative and quantitative data from two hospital databases, a chart audit, surveys and interviews with service users, providers and stakeholders. Contributions were received from 202 participants. Findings: The clinic was highly regarded by all participants. Continuity of care throughout the antenatal period was particularly valued by newly arrived women as it afforded them security and support to negotiate an unfamiliar Western maternity system. Positive experiences decreased however; as women transitioned from the clinic to labour and postnatal wards where they reported that their traditional birthing and recuperative practices were often interrupted by the imposition of Western biomedical notions of appropriate care. The centrally located clinic was problematic, frequently requiring complex travel arrangements. Appointment schedules often impacted negatively on traditional spousal and family obligations. Conclusions: Providing comprehensive and culturally responsive maternity care for women from refugee backgrounds is achievable, however it is also resource intensive. The production of translated information which is high quality in terms of production and content, whilst also taking account of languages which are only rarely encountered, is problematic. Cultural competency programmes for staff, ideally online, require regular updating in light of new knowledge and changing political sensitivities.

HPLC method for preliminary analysis of constituents in rat blood after oral administration of the extract of Acanthopanax senticosus

An HPLC with SPE method has been developed for analysis of constituents in rat blood after oral administration of the extract of Acanthopanax senticosus (ASE). The plasma sample was prepared by SPE method equipped with Oasis HLB cartridge (3cc, 60 mg). The analysis was performed on a Dikma Diamonsil RP(18) column (4.6 mmx150 mm, 5 microm) with the gradient elution of solvent A (ACN) and solvent B (0.1% aqueous phosphoric acid, v/v) and the detection wavelength was set at 270 nm. The calibration curve was linear over the range of 0.156-15.625 microg/mL. The LOD was 60 ng/mL. The intraday precision was less than 5.80%, and the interday precision was less than 6.0%. The recovery was (87.30 +/- 1.73)%. As a result, 19 constituents were detected in rat plasma after oral administration of the ASE, including 11 original compounds in ASE and eight metabolites, and three of the metabolites originated from syringin in ASE. Six constituents were identified by comparing with the corresponding reference compounds.

A phase II study of mitomycin C and oral etoposide for advanced adenocarcinoma of the upper gastrointestinal tract

Background: Mitomycin C and etoposide have both demonstrated activity against gastric carcinoma. Etoposide is a topoisomerase II inhibitor with evidence for phase-specific and schedule-dependent activity. Patients and method. Twenty-eight consecutive patients with advanced upper gastrointestinal adenocarcinoma were treated with intravenous (i.v.) bolus mitomycin C 6 mg/m2 on day 1 every 21 days to a maximum of four courses. Oral etoposide capsules 50 mg b.i.d. (or 35 mg b.i.d. liquid) were administered days 1 to 10 extending to 14 days in subsequent courses if absolute neutrophil count >1.5 x 109/l on day 14 of first course, for up to six courses. Results: Twenty-six patients were assessed for response of whom 12 had measurable disease and 14 evaluable disease. Four patients had a documented response (one complete remission, three partial remissions) with an objective response rate of 15% (95% confidence interval (95% CI) 4%-35%). Eight patients had stable disease and 14 progressive disease. The median survival was six months. The schedule was well tolerated with no treatment-related deaths. Nine patients experienced leucopenia (seven grade II and two grade III). Nausea and vomiting (eight grade II, one grade III), fatigue (eight grade II, two grade III) and anaemia (seven grade II, two grade III) were the predominant toxicities. Conclusion: This out-patient schedule is well tolerated and shows modest activity in the treatment of advanced upper gastrointestinal adenocarcinoma. Further studies using protracted schedules of etoposide both orally and as infusional treatment should be developed.
