The Benefits of Cooperative Inquiry in Health Services Research: Lessons from an Australian Aboriginal and Torres Strait Islander Health Study

Health services research is underpinned by partnerships between researchers and health services. Partnership-based research is increasingly needed to deal with the uncertainty of global pandemics, climate change induced severe weather events, and other disruptions. To date there is very little data on what has happened to health services research during the COVID-19 pandemic. This paper describes the establishment of an Australian multistate Decolonising Practice research project and charts its adaptation in the face of disruptions. The project used cooperative inquiry method, where partner health services contribute as coresearchers. When the COVID-19 pandemic hit, data collection needed to be immediately paused, and when restrictions started to lift, all research plans had to be renegotiated with services. Adapting the research surfaced health service, university, and staffing considerations. Our experience suggests that cooperative inquiry was invaluable in successfully navigating this uncertainty and negotiating the continuance of the research. Flexible, participatory methods such as cooperative inquiry will continue to be vital for successful health services research predicated on partnerships between researchers and health services into the future. They are also crucial for understanding local context and health services priorities and ways of working, and for decolonising Indigenous health research.

Effects of the Connections program on return-to-custody, mortality and treatment uptake among people with a history of opioid use: Retrospective cohort study in an Australian prison system

BACKGROUND AND AIMS

Connections is a voluntary health program that facilitates access to opioid agonist treatment (OAT) and social services for people with opioid use exiting prison. This study aimed to measure the effectiveness of Connections in reducing recidivism and improving health outcomes for people with a history of opioid use on leaving prison.

DESIGN

Retrospective cohort study with quasi-random allocation to the program.

SETTING

Public adult prisons in New South Wales, Australia, 2008-2015.

PARTICIPANTS

Adults released from custody with a history of opioid use. Of 5549 eligible releasees, 3973 were allocated to Connections and 1576 to treatment-as-usual.

MEASUREMENTS

Outcomes were return-to-custody, all-cause mortality, and OAT participation.

FINDINGS

Regression analyses on an intention-to-treat basis, and adjusting for baseline propensity scores, comparing patients allocated to Connections versus treatment-as-usual showed no difference in rates of return-to-custody within 2 years (hazard ratio [HR]: 1.01; 95% confidence interval [CI]: 0.92 -1.12). Patients allocated to the Connections program were more likely to access OAT (odds ratio [OR]: 1.21; 95% CI: 1.06-1.39) and had lower mortality within 28 days of release (0.25% vs. 0.66%; HR: 0.38; 95% CI: 0.14-1.03). Differences in mortality did not persist beyond 28 days. Subgroup analyses showed that allocation to Connections was associated with higher risk of return-to-custody within 28 days for Aboriginal and/or Torres Strait Islander (Indigenous) and female releasees.

CONCLUSIONS

The Connections program for people with opioid use exiting prison did not reduce the likelihood of return-to-custody but did facilitate opioid agonist treatment participation on release from prison.

Prevalence and trends for Aboriginal and Torres Strait Islander children living with cerebral palsy: A birds-eye view

AIM

To provide a birds-eye view of the trends of cerebral palsy (CP) for Australian Aboriginal and Torres Strait Islander children and young adults.

METHOD

Data were obtained for this population-based observational study from the Australian Cerebral Palsy Register (ACPR), birth years 1995 to 2014. The Indigenous status of children was classified by maternal Aboriginal and Torres Strait Islander or non-Indigenous status. Descriptive statistics were calculated for socio-demographic and clinical characteristics. Prenatal/perinatal and post-neonatal birth prevalence was calculated per 1000 live births and per 10 000 live births respectively, and Poisson regression used to assess trends.

RESULTS

Data from the ACPR were available for 514 Aboriginal and Torres Strait Islander individuals with CP. Most children could walk independently (56%) and lived in urban or regional areas (72%). One in five children lived in socioeconomically disadvantaged remote/very remote areas. The birth prevalence of prenatal/perinatal CP declined after the mid-2000s from a high of 4.8 (95% confidence interval 3.2-7.0) to 1.9 per 1000 live births (95% confidence interval 1.1-3.2) (2013-2014), with marked declines observed for term births and teenage mothers.

INTERPRETATION

The birth prevalence of CP in Aboriginal and Torres Strait Islander children in Australia declined between the mid-2000s and 2013 to 2014. This birds-eye view provides key stakeholders with new knowledge to advocate for sustainable funding for accessible, culturally safe, antenatal and CP services.

WHAT THIS PAPER ADDS

Birth prevalence of cerebral palsy (CP) is beginning to decline for Aboriginal and Torres Strait Islanders. Recent CP birth prevalence for Aboriginal and Torres Strait Islanders is 1.9 per 1000 live births. Most children with CP live in more populated areas rather than remote or very remote areas. One in five Aboriginal and Torres Strait Islander children with CP live in socioeconomically disadvantaged remote areas.

Ear health and hearing in urban Aboriginal children

OBJECTIVE

Evaluate ear health and hearing among urban Aboriginal children and quantify relationships with child, family and social factors.

METHODS

Baseline questionnaire and ear health examinations from 1430 children with diagnoses (0.5-18 years) attending Aboriginal Health Services enrolled in SEARCH. Ear health outcomes were Otitis Media (OM), and hearing loss (three-frequency average hearing loss >20dB) diagnosed using pneumatic otoscopy, tympanometry, and audiometry.

RESULTS

Half the children 0.5-3 years had OM (51.5%, 136/264). One third 0.5-18 years (30.4%; 435/1430) had OM, including 1.8% (26/1430) with perforation (0.8% chronic suppurative OM, 0.6% dry perforation and 0.4% acute OM with perforation). One quarter 0.5-18 years (25.7%; 279/1087) had hearing loss; 12.4% unilateral, 13.2% bilateral (70.6% with bilateral loss had concurrent OM). OM was associated with: younger age (0.5-<3 years versus 6-18 years) age-sex-site; adjusted prevalence ratio (aPR)=2.64, 95%, 2.18-3.19); attending childcare/preschool (aPR=1.24, 95%CI, 1.04-1.49); foster care (aPR=1.40, 95%CI, 1.10-1.79); previous ear infection/s (aPR=1.68, 95%CI, 1.42-1.98); and ≥2 people/bedroom (aPR=1.66, 95%CI, 1.24-2.21). Hearing impairment was associated with younger age (0.5-<6 years vs. ≥6 years aPR=1.89, 95%CI, 1.40-2.55) and previous ear infection (aPR=1.87, 95%CI, 1.31-2.68).

CONCLUSIONS

Half the urban Aboriginal children in this cohort had OM and two-thirds with hearing impairment had OM.

IMPLICATIONS FOR PUBLIC HEALTH

Findings highlight importance of early detection and support for ear health, particularly in pre-school-aged children with risk factors.

Developing best practice principles for the provision of programs and services to people transitioning from custody to the community: study protocol for a modified Delphi consensus exercise

INTRODUCTION

There is a lack of standard nomenclature and a limited understanding of programmes and services delivered to people in prisons as they transition into the community to support their integration and reduce reoffending related risk factors. The aim of this paper is to outline the protocol for a modified Delphi study designed to develop expert consensus on the nomenclature and best-practice principles of programmes and services for people transitioning from prison into the community.

METHODS AND ANALYSIS

An online, two-phase modified Delphi process will be conducted to develop an expert consensus on nomenclature and the best-practice principles for these programmes. In the preparatory phase, a questionnaire was developed comprising a list of potential best-practice statements identified from a systematic literature search. Subsequently, a heterogeneous sample of experts including service providers, Community and Justice Services, Not for Profits, First Nations stakeholders, those with lived experience, researchers and healthcare providers will participate in the consensus building phase (online survey rounds and online meeting) to achieve consensus on nomenclature and best-practice principles. Participants will indicate, via Likert scale, to what extent they agree with nomenclature and best-practice statements. If at least 80% of the experts agree to a term or statement (indicated via Likert scale), it will be included in a final list of nomenclature and best-practice statements. Statements will be excluded if 80% experts disagree. Nomenclature and statements not meeting positive or negative consensus will be explored in a facilitated online meeting. Approval from experts will be sought on the final list of nomenclature and best-practice statements.

ETHICS AND DISSEMINATION

Ethical approval has been received from the Justice Health and Forensic Mental Health Network Human Research Ethics Committee, the Aboriginal Health and Medical Research Council Human Research Ethics Committee, the Corrective Services New South Wales Ethics Committee and the University of Newcastle Human Research Ethics Committee. The results will be disseminated via peer-reviewed publication.

Developing and evaluating Birthing on Country services for First Nations Australians: the Building On Our Strengths (BOOSt) prospective mixed methods birth cohort study protocol

BACKGROUND

With the impact of over two centuries of colonisation in Australia, First Nations families experience a disproportionate burden of adverse pregnancy and birthing outcomes. First Nations mothers are 3-5 times more likely than other mothers to experience maternal mortality; babies are 2-3 times more likely to be born preterm, low birth weight or not to survive their first year. 'Birthing on Country' incorporates a multiplicity of interpretations but conveys a resumption of maternity services in First Nations Communities with Community governance for the best start to life. Redesigned services offer women and families integrated, holistic care, including carer continuity from primary through tertiary services; services coordination and quality care including safe and supportive spaces. The overall aim of Building On Our Strengths (BOOSt) is to facilitate and assess Birthing on Country expansion into two settings - urban and rural; with scale-up to include First Nations-operated birth centres. This study will build on our team's earlier work - a Birthing on Country service established and evaluated in an urban setting, that reported significant perinatal (and organisational) benefits, including a 37% reduction in preterm births, among other improvements.

METHODS

Using community-based, participatory action research, we will collaborate to develop, implement and evaluate new Birthing on Country care models. We will conduct a mixed-methods, prospective birth cohort study in two settings, comparing outcomes for women having First Nations babies with historical controls. Our analysis of feasibility, acceptability, clinical and cultural safety, effectiveness and cost, will use data including (i) women's experiences collected through longitudinal surveys (three timepoints) and yarning interviews; (ii) clinical records; (iii) staff and stakeholder views and experiences; (iv) field notes and meeting minutes; and (v) costs data. The study includes a process, impact and outcome evaluation of this complex health services innovation.

DISCUSSION

Birthing on Country applies First Nations governance and cultural safety strategies to support optimum maternal, infant, and family health and wellbeing. Women's experiences, perinatal outcomes, costs and other operational implications will be reported for Communities, service providers, policy advisors, and for future scale-up.

Aroha and Manaakitanga-That's What It Is About: Indigenous Women, "Love," and Interpersonal Violence

Māori women (Aotearoa New Zealand's Indigenous women) experience a high burden of harm and homicide associated with intergenerational family violence, complicated by the ongoing effects of colonialism. Also, the historical, social, and cultural complexities, such as poverty and structural racism, challenge further Māori women seeking help. In this project, we sought to answer two questions: What are Māori women's sociocultural constructions of "love" within relationships with violent partners? What roles do traditional cultural values play in their relationships? Using Kaupapa Māori (by Māori, for Māori) methodology, we conducted in-depth semi-structured interviews with 27 Māori women and analyzed them using thematic analysis. We identified three core themes that explain how Māori women enter into, stay in, and leave a relationship with a violent partner: (a) it begins with a connection, (b) downplaying the signs, and (c) needing to leave. We found that Māori women's compassion and caring for their partner was underpinned by their recognition that partners had the potential to be nonviolent and resembled Māori cultural concepts of aroha (compassion, empathy, and respect) and manaakitanga (hospitality, sharing, and caring for others). Through sharing their stories, these women revealed the strength of cultural imperatives that include the importance of whakapapa (genealogy) and whanaungatanga (connections) of which aroha and manaakitanga are integral parts. Our findings highlight the complexity and competing tensions underpinning Māori women's decision-making when entering and exiting violent relationships. These cultural imperatives are essential for understanding how these influence the decision-making of Māori women, which can position them at odds with those who would tell them they must walk away and not look back.

A call for action that cannot go to voicemail: Research activism to urgently improve Indigenous perinatal health and wellbeing

In this call to action, a coalition of Indigenous and non-Indigenous researchers from Australia, Aotearoa New Zealand, United States and Canada argue for the urgent need for adequately funded Indigenous-led solutions to perinatal health inequities for Indigenous families in well-resourced settler-colonial countries. Authors describe examples of successful community-driven programs making a difference and call on all peoples to support and resource Indigenous-led perinatal health services by providing practical actions for individuals and different groups.

Incarcerated aboriginal women's experiences of accessing healthcare and the limitations of the 'equal treatment' principle

Background

Colonization continues in Australia, sustained through institutional and systemic racism. Targeted discrimination and intergenerational trauma have undermined the health and wellbeing of Australia’s Aboriginal and Torres Strait Islander population, leading to significantly poorer health status, social impoverishment and inequity resulting in the over-representation of Aboriginal people in Australian prisons. Despite adoption of the ‘equal treatment’ principle, on entering prison in Australia entitlements to the national universal healthcare system are revoked and Aboriginal people lose access to health services modelled on Aboriginal concepts of culturally safe healthcare available in the community. Incarcerated Aboriginal women experience poorer health outcomes than incarcerated non-Indigenous women and Aboriginal men, yet little is known about their experiences of accessing healthcare. We report the findings of the largest qualitative study with incarcerated Aboriginal women in New South Wales (NSW) Australia in over 15 years.

Methods

We employed a decolonizing research methodology, ‘community collaborative participatory action research’, involving consultation with Aboriginal communities prior to the study and establishment of a Project Advisory Group (PAG) of community expert Aboriginal women to guide the project. Forty-three semi-structured interviews were conducted in 2013 with Aboriginal women in urban and regional prisons in NSW. We applied a grounded theory approach for the data analysis with guidance from the PAG.

Results

Whilst Aboriginal women reported positive and negative experiences of prison healthcare, the custodial system created numerous barriers to accessing healthcare. Aboriginal women experienced institutional racism and discrimination in the form of not being listened to, stereotyping, and inequitable healthcare compared with non-Indigenous women in prison and the community.

Conclusions

‘Equal treatment’ is an inappropriate strategy for providing equitable healthcare, which is required because incarcerated Aboriginal women experience significantly poorer health. Taking a decolonizing approach, we unpack and demonstrate the systems level changes needed to make health and justice agencies culturally relevant and safe. This requires further acknowledgment of the oppressive transgenerational effects of ongoing colonial policy, a true embracing of diversity of worldviews, and critically the integration of Aboriginal concepts of health at all organizational levels to uphold Aboriginal women’s rights to culturally safe healthcare in prison and the community.

Case study of a decolonising Aboriginal community controlled comprehensive primary health care response to alcohol-related harm

OBJECTIVE

This paper provides a case study of the responses to alcohol of an Aboriginal Community Controlled Health Service (The Service), and investigates the implementation of comprehensive primary health care and how it challenges the logic of colonial approaches.

METHODS

Data were drawn from a larger comprehensive primary health care study. Data on actions on alcohol were collected from: a) six-monthly service reports of activities; b) 29 interviews with staff and board members; c) six interviews with advocacy partners; and d) community assessment workshops with 13 service users.

RESULTS

The Service engaged in rehabilitative, curative, preventive and promotive work targeting alcohol, including advocacy and collaborative action on social determinants of health. It challenged other government approaches by increasing Aboriginal people's control, providing culturally safe services, addressing racism, and advocating to government and industry.

CONCLUSIONS

This case study provides an example of implementation of the full continuum of comprehensive primary health care activities. It shows how community control can challenge colonialism and ongoing power imbalances to promote evidence-based policy and practice that support self-determination as a positive determinant for health. Implications for public health: Aboriginal Community Controlled Health Services are a good model for comprehensive primary health care approaches to alcohol control.

Holistic Conceptualizations of Health by Incarcerated Aboriginal Women in New South Wales, Australia

While there has been extensive research on the health and social and emotional well-being (SEWB) of Aboriginal women in prison, there are few qualitative studies where incarcerated Aboriginal women have been directly asked about their health, SEWB, and health care experiences. Using an Indigenous research methodology and SEWB framework, this article presents the findings of 43 interviews with incarcerated Aboriginal women in New South Wales, Australia. Drawing on the interviews, we found that Aboriginal women have holistic conceptualizations of their health and SEWB that intersect with the SEWB of family and community. Women experience clusters of health problems that intersect with intergenerational trauma, perpetuated and compounded by ongoing colonial trauma including removal of children. Women are pro-active about their health but encounter numerous challenges in accessing appropriate health care. These rarely explored perspectives can inform a reframing of health and social support needs of incarcerated Aboriginal women establishing pathways for healing.

Recidivism, health and social functioning following release to the community of NSW prisoners with problematic drug use: study protocol of the population-based retrospective cohort study on the evaluation of the Connections Program

INTRODUCTION

The rising rate of incarceration in Australia, driven by high reoffending, is a major public health problem. Problematic drug use is associated with increasing rates of reoffending and return to custody of individuals. Throughcare provides support to individuals during imprisonment through to post-release, improving both the transition to community and health outcomes post-incarceration. The aim of this study is to evaluate the Connections Programme (CP) that utilises a throughcare approach for release planning of people in prison with a history of problematic drug use. The study protocol is described.

METHODS AND ANALYSIS

Population-based retrospective cohort study. The study will use record linkage of the Connections dataset with 10 other New South Wales (NSW) population datasets on offending, health service utilisation, opioid substitution therapy, pregnancy, birth and mortality. The study includes all patients who were eligible to participate in the CP between January 2008 and December 2015 stratified by patients who were offered CP and eligible patients who were not offered the programme (non-CP (NCP)). Propensity-score matching will be used to appropriately adjust for the observable differences between CP and NCP. The differences between two groups will be examined using appropriate univariate and multivariate analyses. A generalised estimating equation approach, which can deal with repeat outcomes for individuals will be used to examine recidivism, mortality and other health outcomes, including perinatal and infant outcomes. Survival analysis techniques will be used to examine the effect of the CP by sex and Indigenous status on the 'time-to' health-related outcomes after adjusting for potential confounders.

ETHICS AND DISSEMINATION

Ethical approval was received from the NSW Population and Health Services Research Ethics Committee, the Justice Health and Forensic Mental Health Network Human Research Ethics Committee, the Aboriginal Health and Medical Research Council Ethics Committee, the Corrective Services NSW Ethics Committee and the University of Technology Sydney Human Research Ethics Committee.

Reflecting and learning: A grounded theory on reframing deficit views of young indigenous women and safety

Often young indigenous women are framed in ways that problematize and pathologize them, which overlooks their strengths. We interviewed 16 young Indigenous Māori women aged 14 to 18 years about their understandings of safety, being safe, and how they kept themselves and their friends safe. Reflecting and Learning, aided by progressing age and maturity, is the process that mediated their feeling unsafe and keeping safe and resulted in being safe. Young Māori women's reflecting and learning facilitates relatively mature levels of resourcefulness for navigating being safe, including situations they encountered appear unsafe.

Aboriginal mothers in prison in Australia: a study of social, emotional and physical wellbeing

OBJECTIVE

To describe the social, emotional and physical wellbeing of Aboriginal mothers in prison.

METHODS

Cross-sectional survey, including a Short Form Health Survey (SF-12) and Kessler Psychological Distress Scale (5-item version) administered to Aboriginal women who self-identified as mothers.

RESULTS

Seventy-seven Aboriginal mothers in New South Wales (NSW) and 84 in Western Australia (WA) participated in the study. Eighty-three per cent (n=59) of mothers in NSW were in prison for drug-related offences, 64.8% (n=46) of mothers in WA were in prison for offences committed under the influence of alcohol. Sixty-eight per cent (n=52) of mothers in NSW and 35% (n=28) of mothers in WA reported mental health problems. Physical (PCS) and Mental (MCS) component scores of SF-12 varied for mothers in NSW and WA. Mothers in NSW experienced poorer health and functioning than mothers in WA (NSW: PCS 49.5, MCS 40.6; WA: PCS 54.4, MCS 48.3) and high levels of psychological distress (NSW: 13.1; WA 10.1).

CONCLUSIONS

Aboriginal mothers in prison have significant health needs associated with physical and mental health, and psychological distress. Implications for public health: Adoption of social and emotional wellbeing as an explanatory framework for culturally secure healthcare in prison is essential to improving health outcomes of Aboriginal mothers in prison in Australia.

Racial and cultural minority experiences and perceptions of health care provision in a mid-western region

Background

Disparities across a number of health indicators between the general population and particular racial and cultural minority groups including African Americans, Native Americans and Latino/a Americans have been well documented. Some evidence suggests that particular groups may receive poorer standards of care due to biased beliefs or attitudes held by health professionals. Less research has been conducted in specifically non-urban areas with smaller minority populations.

Methods

This study explored the self-reported health care experiences for 117 racial and cultural minority Americans residing in a Mid-Western jurisdiction. Prior health care experiences (including perceived discrimination), attitudes towards cultural competence and satisfaction with health care interactions were ascertained and compared across for four sub-groups (African-American, Native American, Latino/a American, Asian American). A series of multiple regression models then explored relationships between a concert of independent variables (cultural strength, prior experiences of discrimination, education level) and health care service preferences and outcomes.

Results

Overall, racial/cultural minority groups (African Americans, Native Americans, Latino/a Americans, and Asian Americans) reported general satisfaction with current healthcare providers, low levels of both health care provider racism and poor treatment, high levels of cultural strength and good access to health care services. Native American participants however, reported more frequent episodes of poor treatment compared to other groups. Incidentally, poor treatment predicted lower levels of treatment satisfaction and racist experiences predicted being afraid of attending conventional health care services. Cultural strength predicted a preference for consulting a health care professional from the same cultural background.

Conclusions

This study provided a rare insight into minority health care expectations and experiences in a region with comparatively lower proportions of racial and cultural minorities. Additionally, the study explored the impact of cultural strength on health care interactions and outcomes. While the bulk of the sample reported satisfaction with treatment, the notable minority of participants reporting poor treatment is still of some concern. Cultural strength did not appear to impact health care behaviours although it predicted a desire for cultural matching. Implications for culturally competent health care provision are discussed within.

T1-Enhanced MRI-visible nanoclusters for imaging-guided drug delivery

Iron oxide nanoparticles with extremely low dimensions have recently been explored as positive (T₁) contrast agent for magnetic resonance imaging (MRI). However, their small sizes lead to fast renal clearance and limit their use in elongated in vivo tracking or therapy monitoring. In this paper, we present a state of art approach to forming nanoclusters by crosslinking ultrasmall iron oxide nanoparticles with bovine serum albumin. This novel design not only maintains the T₁ performance of the ultrasmall nanoparticles, but also significantly increases their blood circulation times from 15 minutes to over two hours. Our breast tumor model study also exhibited enhanced contrast at tumor sites for more than 24 hours. The ability of maintaining the T₁ performance of the ultrasmall nanoparticles is significant, because previous studies have shown complete T₁ loss or signal decrease upon polymer encapsulation. This design also shows great potential in encapsulating model drug molecules, which will greatly benefit the field of imaging-guided drug delivery.

The impact of indigenous cultural identity and cultural engagement on violent offending

BACKGROUND

Possessing a strong cultural identity has been shown to protect against mental health symptoms and buffer distress prompted by discrimination. However, no research to date has explored the protective influences of cultural identity and cultural engagement on violent offending. This paper investigates the relationships between cultural identity/engagement and violent recidivism for a cohort of Australian Indigenous people in custody.

METHODS

A total of 122 adults from 11 prisons in the state of Victoria completed a semi-structured interview comprising cultural identification and cultural engagement material in custody. All official police charges for violent offences were obtained for participants who were released from custody into the community over a period of 2 years.

RESULTS

No meaningful relationship between cultural identity and violent recidivism was identified. However a significant association between cultural engagement and violent recidivism was obtained. Further analyses demonstrated that this relationship was significant only for participants with a strong Indigenous cultural identity. Participants with higher levels of cultural engagement took longer to violently re-offend although this association did not reach significance.

CONCLUSIONS

For Australian Indigenous people in custody, 'cultural engagement' was significantly associated with non-recidivism. The observed protective impact of cultural engagement is a novel finding in a correctional context. Whereas identity alone did not buffer recidivism directly, it may have had an indirect influence given its relationship with cultural engagement. The findings of the study emphasize the importance of culture for Indigenous people in custody and a greater need for correctional institutions to accommodate Indigenous cultural considerations.

Genetic and environmental factors influence Listeria monocytogenes nisin resistance

AIMS

Listeria monocytogenes nisin resistance increases when first exposed to NaCl and other stresses, such as low pH. In addition to environmental stressors, specific genomic elements can confer nisin resistance, such as the stress survival islet (SSI-1). As SSI-1 is variably present among L. monocytogenes strains, we wanted to determine if SSI-1 was associated with salt-induced nisin resistance.

METHODS AND RESULTS

The presence of SSI-1 was determined using PCR for 48 strains of L. monocytogenes. When combined with multilocus sequence typing data, we found that the distribution of SSI-1 is clonal, where strains from clonal complexes (CC) 2, 6 and 11 do not have SSI-1, while strains from CCs 3, 5, 7 and 9 contain SSI-1. The impact of SSI-1 on salt-induced nisin resistance was dependent on CC. The average log decrease after 24 h of exposure to nisin at 7°C under salt-inducing conditions was 2·6 ± 1·1 for CC 9 strains and 2·3 ± 0·7 for CC 11 strains, which had significantly lower survival compared to the other CCs, such as 1·3 ± 0·3 for CC 6. Deletion of SSI-1 from a CC 7 strain demonstrated the role SSI-1 plays in salt-induced nisin resistance, as the deletion mutant had lower resistance compared to the parent strain.

CONCLUSIONS

These data suggest that inducible nisin resistance in L. monocytogenes can be influenced by environmental conditions as well as the genetic composition of the strain, which should be considered when selecting control measures for ready-to-eat foods.

SIGNIFICANCE AND IMPACT OF THE STUDY

The foodborne pathogen L. monocytogenes can grow in suboptimal conditions, including low temperature and high osmolarity, which makes it a safety concern for ready-to-eat foods. When using antimicrobial peptide inhibitors such as nisin, it is important to understand how food components can impact antimicrobial resistance across the genetic diversity of L. monocytogenes.

Shape-dependent cellular behaviors and relaxivity of iron oxide-based T1 MRI contrast agents

Recent research efforts about iron oxide nanoparticles has focused on the development of iron oxide-based T₁ contrast agents for magnetic resonance imaging (MRI), such as ultrasmall iron oxide nanospheres (USNPs <4 nm) and ultrathin nanowires (NW, diameter <4 nm). In this paper, we report the cellular uptake behaviors of these two types of ultrasmall scale nanostructures on HepG2 cells. Both these two nanostructures were functionalized with tannic acid and their physical and chemical properties were carefully analyzed before cellular tests. Both USNPs and NWs exhibited strong paramagnetic signals, a property suitable for T₁ MRI contrast agents. The distinct shapes also caused much difference in their cellular uptake behaviors. Specifically, the uptake of USNPs was five times higher than that of NWs after 72 hours incubation. The shape-dependent cellular uptake can potentially lead to different blood circulation times, and subsequently different applications of these two types of ultrasmall nanostructures.

REM

The well-documented health disparities between the Australian Indigenous and non-Indigenous population mandates a comprehensive response from health professionals. This article outlines the approach taken by one faculty of health in a large urban Australian university to enhance cultural competence in students from a variety of fields. Here we outline a collaborative and deeply respectful process of Indigenous and non-Indigenous university staff collectively developing a model that has framed the embedding of a common faculty Indigenous graduate attribute across the curriculum. Through collaborative committee processes, the development of the principles of “Respect; Engagement and sharing; Moving forward” (REM) has provided both a framework and way of “being and doing” our work. By drawing together the recurring principles and qualities that characterize Indigenous cultural competence the result will be students and staff learning and bringing into their lives and practice, important Indigenous cultural understanding.

An assessment of the doses received by members of the public in Japan following the nuclear accident at Fukushima Daiichi nuclear power plant

The earthquake and tsunami on 11 March 2011, centred off the east coast of Japan, caused considerable destruction and substantial loss of life along large swathes of the Japanese coastline. The tsunami damaged the Fukushima Daiichi nuclear power plant (NPP), resulting in prolonged releases of radioactive material into the environment. This paper assesses the doses received by members of the public in Japan. The assessment is based on an estimated source term and atmospheric dispersion modelling rather than monitoring data. It is evident from this assessment that across the majority of Japan the estimates of dose are very low, for example they are estimated to be less than the annual average dose from natural background radiation in Japan. Even in the regions local to Fukushima Daiichi NPP (and not affected by any form of evacuation) the maximum lifetime effective dose is estimated to be well below the cumulative natural background dose over the same period. The impact of the urgent countermeasures on the estimates of dose was considered. And the relative contribution to dose from the range of exposure pathways and radionuclides were evaluated. Analysis of estimated doses focused on the geographic irregularity and the impact of the meteorological conditions. For example the dose to an infant's thyroid received over the first year was estimated to be greater in Hirono than in the non-evacuated region of Naraha, despite Hirono being further from the release location. A number of factors were identified and thought to contribute towards this outcome, including the local wind pattern which resulted in the recirculation of part of the release. The non-uniform nature of dose estimates strengthens the case for evaluations based on dispersion modelling.

The role of primary health care services to better meet the needs of Aboriginal Australians transitioning from prison to the community

Background

Aboriginal Australians are more likely than other Australians to cycle in and out of prison on remand or by serving multiple short sentences—a form of serial incarceration and institutionalisation. This cycle contributes to the over-representation of Aboriginal Australians in prison and higher rates of recidivism. Our research examined how primary health care can better meet the health care and social support needs of Aboriginal Australians transitioning from prison to the community.

Methods

Purposive sampling was used to identify 30 interviewees. Twelve interviews were with Aboriginal people who had been in prison; ten were with family members and eight with community service providers who worked with former inmates. Thematic analysis was conducted on the interviewees’ description of their experience of services provided to prisoners both during incarceration and on transition to the community.

Results

Interviewees believed that effective access to primary health care on release and during transition was positively influenced by providing appropriate healthcare to inmates in custody and by properly planning for their release. Further, interviewees felt that poor communication between health care providers in custody and in the community prior to an inmate’s release, contributed to a lack of comprehensive management of chronic conditions. System level barriers to timely communication between in-custody and community providers included inmates being placed on remand which contributed to uncertainty regarding release dates and therefore difficulties planning for release, cycling in and out of prison on short sentences and being released to freedom without access to support services.

Conclusions

For Aboriginal former inmates and family members, release from prison was a period of significant emotional stress and commonly involved managing complex needs. To support their transition into the community, Aboriginal former inmates would benefit from immediate access to culturally- responsive community -primary health care services. At present, however, pre-release planning is not always available, especially for Aboriginal inmates who are more likely to be on remand or in custody for less than six months.

Decolonisation: A critical step for improving Aboriginal health

Aboriginal health continues to be in crisis in Australia although expenditure has increased in service provision, strategic planning, research and policy development over the last thirty years. This paper recommends that a shift must occur to make Aboriginal health improvement a reality. This shift requires the decolonising of Aboriginal health so that the experts in Aboriginal health, namely Aboriginal people, can voice and action initiatives that address their health issues. This shift is from the current western dominant approach that continues to manage Aboriginal health in its linear spectrum of illness and disease. Aboriginal people view health differently; their contexts for health issues are also diverse requiring a more holistic and informed response.

Reframing spaces by building relationships: community collaborative participatory action research with Aboriginal mothers in prison

Aboriginal women are vastly over-represented in the Australian prison system. Their recidivism rates are high. Aboriginal women in contact with the criminal justice system also have higher rates of mental health disorders and are likely to have been a victim of violence. The majority of these women are mothers. Their increasing incarceration therefore has serious implications for the health and social and emotional wellbeing of their Aboriginal children, families and communities. Illustrating and exploring this situation requires an Indigenous informed conceptual framework utilising a decolonising research methodology inclusive of enduring community and stakeholder dialogue and consultation. Respectful and ethical praxis are central to this approach. We will describe how this methodology has been applied within a current National Health and Medical Research Council (NHMRC) research project in NSW, Australia. The NHMRC guidelines for research with Aboriginal and Torres Strait Islanders peoples have supported our process and will be highlighted in illustrating our research experience.

Working together to make Indigenous health care curricula everybody's business: a graduate attribute teaching innovation report

Previously there has been commitment to the idea that Indigenous curricula should be taught by Indigenous academic staff, whereas now there is increasing recognition of the need for all academic staff to have confidence in enabling Indigenous cultural competency for nursing and other health professional students. In this way, Indigenous content can be threaded throughout a curriculum and raised in many teaching and learning situations, rather than being siloed into particular subjects and with particular staff. There are many sensitivities around this change, with potential implications for Indigenous and non-Indigenous students and staff, and for the quality of teaching and learning experiences. This paper reports on a collaborative process that was used to reconceptualise how Indigenous health care curricula would be positioned throughout a programme and who would or could work with students in this area. Effective leadership, establishing a truly collaborative environment, acknowledging fears and perceived inadequacies, and creating safe spaces for sharing and learning were crucial in effecting this change.

Who is not coping with colonization? Laying out the map for decolonization

OBJECTIVE

This paper explores reasons for using decolonization as a method for improving Indigenous health status. Decolonization is a method required to shift the current paradigm of Western dominance and colonial amnesia that constructs and maintains Indigenous poor health status.

CONCLUSION

Decolonization requires every Australian to examine the impact colonization has upon their past and present in order to formulate a future that does not reinstate the past. To take these steps requires a balance of histories, informing our current political and social context, critical reflexive practice and open communication with Aboriginal and Torres Strait Islander peoples.
