Abstract
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.

Abstract
OBJECTIVE Some countries have implemented systems to monitor suicides in real-time. These systems differ because of the various ways in which suicides are identified and recorded. The main objective of this study was to conduct an international comparison of major real-time suicide mortality surveillance systems to identify joint strengths, challenges, and differences, and thereby inform best-practice criteria at local, national, and international levels. METHODS Five major real-time suicide mortality surveillance systems of various coverage levels were identified and selected for review via an internet-based scoping exercise and prior knowledge of existing systems. Key information including the system components and practices was collated from those organizations that developed and operate each system using a structured template. The information was narratively and critically synthesized to determine similarities and differences between the systems. RESULTS The comparative review of the five established real-time suicide surveillance systems revealed more commonalities than differences overall. Commonalities included rapid, routine surveillance based on minimal, provisional data to facilitate timely intervention and postvention efforts. Identified differences include the timeliness of case submission and system infrastructure. CONCLUSION The recommended criteria could promote replicable components and practices in real-time suicide surveillance while offering flexibility in adapting to regional/local circumstances and resource availability.HIGHLIGHTSEvidence-informed recommendations for current best practice in real-time suicide surveillance.Proposed comprehensive framework can be adapted based on available resources and capacity.Real-time suicide mortality data facilitates rapid data-driven decision-making in suicide prevention.

Abstract
Introduction Many Aboriginal and Torres Strait Islander people living on Kaurna Country in northern Adelaide experience adverse health and social circumstances. The Taingiwilta Pirku Kawantila study sought to understand challenges facing Aboriginal and Torres Strait Islander communities and identify solutions for the health and social service system to promote social and emotional wellbeing. Methods This qualitative study applied Indigenous methodologies undertaken with Aboriginal and Torres Strait Islander governance and leadership. A respected local Aboriginal person engaged with Aboriginal and Torres Strait Islander community members and service providers through semi-structured interviews and yarning circles that explored community needs and challenges, service gaps, access barriers, success stories, proposed strategies to address service and system challenges, and principles and values for service design. A content analysis identified the breadth of challenges in addition to describing key targets to empower and connect communities and optimize health and social services to strengthen individual and collective social and emotional wellbeing. Results Eighty-three participants contributed to interviews and yarning circles including 17 Aboriginal community members, 38 Aboriginal and Torres Strait Islander service providers, and 28 non-Indigenous service providers. They expressed the need for codesigned, strengths-based, accessible and flexible services delivered by Aboriginal and Torres Strait Islander workers with lived experience employed in organisations with Aboriginal and Torres Strait Islander leadership and governance. Community hubs and cultural events in addition to one-stop-shop service centres and pre-crisis mental health, drug and alcohol and homelessness services were among many strategies identified. Conclusion Holistic approaches to the promotion of social and emotional wellbeing are critical. Aboriginal and Torres Strait Islander people are calling for places in the community to connect and practice culture. They seek culturally safe systems that enable equitable access to and navigation of health and social services. Aboriginal and Torres Strait Islander workforce leading engagement with clients is seen to safeguard against judgement and discrimination, rebuild community trust in the service system and promote streamlined access to crucial services.

Abstract
AIMS There is clear evidence that installing safety barriers is effective in preventing jumping suicides from high-risk bridges with only moderate displacement to other nearby bridges. However, the impact of barriers on jumping suicides across broader geographical areas is not well understood. We examined patterns in jumping suicides across the state of Victoria, Australia, after a safety barrier was installed at the West Gate Bridge which, before the installation of the barrier, was the site of approximately 40% of Victoria's jumping suicides. METHODS We used negative binomial regression analyses on Victorian data from 2000 to 2019 to compare rates of jumping suicides at the West Gate Bridge, other bridges and non-bridge jumping locations before, during and after the West Gate Bridge barrier installation. We conducted linear regression analyses to examine whether the distance travelled from the deceased's usual residence to the location of their jumping suicide changed between the before, during and after barrier installation periods. RESULTS After installation of the barrier, there were no jumping suicides at the West Gate Bridge (rate ratio [RR] = 0.00, 95% credible intervals [95% Cr] = 0.00-0.0001) and there was strong evidence that the rate of jumping suicides at all locations declined by 65% (RR = 0.35, 95% Cr = 0.22-0.54). At other bridges, there was also evidence of a reduction (RR = 0.31, 95% Cr = 0.11-0.70), but there was no evidence of a change at non-bridge locations (RR = 0.74, 95% Cr = 0.39-1.30). CONCLUSION After installation of the safety barrier at the West Gate Bridge, jumping suicide in Victoria decreased overall and at other bridges, and did not appear to change at non-bridge locations. Our findings show that when barriers are installed at a site responsible for a disproportionately high number of jumping suicides, they are not only highly effective at the site where the barriers are installed but can also have a prevention impact beyond the immediate locale at similar sites.

Abstract
We have used the LOw-Frequency ARray (LOFAR) to search for the growing tip of an intra-cloud (IC) positive leader. Even with our most sensitive beamforming method, where we coherently add the signals of about 170 antenna pairs, we were not able to detect any emission from the tip. Instead, we put constraints on the emissivity of very-high frequency (VHF) radiation from the tip at 0.5 pJ/MHz at 60 MHz, integrated over 100 ns. The limit is independent on whether this emission is in the form of short pulses or continuously radiating. The non-observation of VHF radiation from intra-cloud positive leaders implies that they proceed in an extremely gradual process, which is in sharp contrast with the observations of other parts of a lightning discharge.

Abstract
Abstract
Background
The sodium glucose co-transporter 2 (SGLT2) inhibitor dapagliflozin reduced the risk of hospitalization for heart failure (HHF) or cardiovascular death (CVD) and the risk of kidney events in patients type 2 diabetes mellitus (T2DM) and high cardiovascular risk or chronic kidney disease in the DECLARE-TIMI 58 and DAPA-CKD trials. These events are more common at lower levels of kidney function. Combining data from the two trials creates an opportunity to examine the effect of dapagliflozin across the spectrum of baseline kidney function.
Purpose
To determine the effects of dapagliflozin on HHF/CVD and kidney endpoints across a broad range of kidney function in the combined dataset.
Methods
We conducted a post hoc analysis of pooled patient-level data from DECLARE and DAPA-CKD. The effects of dapagliflozin compared with placebo on HHF/CVD and kidney endpoints (defined as sustained eGFR decrease ≥40%, end-stage kidney disease, or renal death) were assessed in the combined cohorts and in subgroups of baseline eGFR (<45, 45-<60, 60-<90, ≥90 mL/min/1.73 m2) and urinary albumin:creatinine ratio (UACR) (<30, 30-<300, 300-<1000, ≥1000 mg/g).
Results
A total of 19,748 patients with T2DM were included. Median (IQR) follow up time was 4.1 (3.7–4.4) years. Median eGFR was 85 (65–95) mL/min/1.73 m2 and UACR 18.2 (7–135) mg/g. Overall, dapagliflozin reduced the risk of HHF/CVD by 18% (HR 0.82, 95% CI 0.73–0.92, p<0.001) and kidney endpoints by 40% (HR 0.60, 95% CI 0.52–0.69, p<0.001). Overall rates of HHF/CVD and kidney endpoints were higher with lower eGFR (p<0.001) and with higher UACR (p<0.001). There were consistent relative risk reductions in HHF/CVD and kidney events with dapagliflozin across eGFR (p-interaction 0.25 and 0.32, respectively, Figure 1) and UACR (p-interaction 0.29 and 0.83, respectively, Figure 2) subgroups. The absolute rate difference (ARD) with dapagliflozin for CVD/HHF ranged from 0.1 events per 1000 patient years in patients in normal categories of eGFR and UACR to 1.0–1.7 events in patients in the most abnormal categories. Likewise, the ARD for kidney events ranged from 0.2 events per 1000 patient years in the normal eGFR and UACR groups to 2.5–4.3 events in patients in the most abnormal categories.
Conclusion
In this pooled analysis of pts with T2DM, there was higher risk of HHF/CVD and kidney events with lower eGFR and higher UACR. Dapagliflozin consistently reduced these events regardless of baseline eGFR and UACR, with large absolute risk reductions in patients with lower eGFR and higher UACR.

Abstract
BACKGROUND The Learning Assistant (LA) model with its subsequent support and training has evidenced significant gains for undergraduate STEM learning and persistence, especially in high-stakes courses like Calculus. Yet, when a swift and unexpected transition occurs from face-to-face to online, remote learning of the LA environment, it is unknown how LAs are able to maintain their motivation (competence, autonomy, and relatedness), adapt to these new challenges, and sustain their student-centered efforts. This study used Self-Determination Theory (SDT) to model theoretical aspects of LAs' motivations (persistence and performance) both before and after changes were made in delivery of a Calculus II course at Texas Tech University due to COVID-19 interruptions. RESULTS Analysis of weekly written reflections, a focus group session, and a post-course questionnaire of 13 Calculus II LAs throughout Spring semester of 2020 showed that LAs' reports of competence proportionally decreased when they transitioned online, which was followed by a moderate proportional increase in reports of autonomy (actions they took to adapt to distance instruction) and a dramatic proportional increase in reports of relatedness (to build structures for maintaining communication and building community with undergraduate students). CONCLUSIONS Relatedness emerged as the most salient factor from SDT to maintain LA self-determination due to the COVID-19 facilitated interruption to course delivery in a high-stakes undergraduate STEM course. Given that online learning continues during the pandemic and is likely to continue after, this research provides an understanding to how LAs responded to this event and the mounting importance of relatedness when LAs are working with undergraduate STEM learners. Programmatic recommendations are given for enhancing LA preparation including selecting LAs for autonomy and relatedness factors (in addition to competence), modeling mentoring for remote learners, and coaching in best practices for online instruction.

Abstract
BACKGROUND AND PURPOSE Cellular uptake of the manganese ion, when administered as a contrast agent for MR imaging, can noninvasively highlight cellular activity and disease processes in both animals and humans. The purpose of this study was to explore the enhancement profile of manganese in patients with multiple sclerosis. MATERIALS AND METHODS Mangafodipir is a manganese chelate that was clinically approved for MR imaging of liver lesions. We present a case series of 6 adults with multiple sclerosis who were scanned at baseline with gadolinium, then injected with mangafodipir, and followed at variable time points thereafter. RESULTS Fourteen new lesions formed during or shortly before the study, of which 10 demonstrated manganese enhancement of varying intensity, timing, and spatial pattern. One gadolinium-enhancing extra-axial mass, presumably a meningioma, also demonstrated enhancement with manganese. Most interesting, manganese enhancement was detected in lesions that formed in the days after mangafodipir injection, and this enhancement persisted for several weeks, consistent with contrast coming from intracellular uptake of manganese. Some lesions demonstrated a diffuse pattern of manganese enhancement in an area larger than that of both gadolinium enhancement and T2-FLAIR signal abnormality. CONCLUSIONS This work demonstrates the first use of a manganese-based contrast agent to enhance MS lesions on MR imaging. Multiple sclerosis lesions were enhanced with a temporal and spatial profile distinct from that of gadolinium. Further experiments are necessary to uncover the mechanism of manganese contrast enhancement as well as cell-specific uptake.

Abstract
OBJECTIVE To measure public opinion about access to abortion in South Australia. METHODS An online survey conducted in 2019. SPSS statistical package version 22 was used for data analysis, with data weighted by age, gender, and region. RESULTS The majority (65%) of the 1,012 respondents supported the ready availability of abortion care and an additional 25% supported availability in certain circumstances. Most (70%) were unaware that abortion remains in criminal law and 80% supported decriminalisation. Support for safe access zones (88%) and the application of existing protections (69%) and obligations (94%) for conscientious objectors was high. A majority (63%) considered that later abortion should be available 'when the woman and her healthcare team decide it is necessary'. CONCLUSIONS These results confirm the trend of increasing support for access to abortion and add two new insights. There was majority support for using existing general protections for the rights and obligations of those with a conscientious objection to abortion. Second, there was strong support for decisions about later abortion to be decided through normal clinical consultation. These results indicate general community approval of abortion being normalised as healthcare, with the safeguards and accountabilities that status entails. Implications for public health: These results invite repeal of special laws about abortion care, to enable better access.

Abstract
Objective The aim of this study was to identify the contribution of Aboriginal Health Workers and Liaison Officers (AHWLOs) to quality of care in the acute health care setting in Australia. Methods A systematic review of peer-reviewed literature focused on the role of AHWLOs and quality processed and quality outcomes. Authors undertook study selection based on inclusion criteria and performed quality assessment using critical appraisal tools from the Joanna Briggs Institute. Results The search revealed limited literature that met the inclusion criteria, namely four quantitative studies and one mixed-methods study. The settings of the included studies were mental health and cardiac care units within various hospitals. The studies indicated that AHWLOs may have a positive effect on communication between healthcare professionals and patients, rates of discharge against medical advice and continuity of care. Methodological constraints among the included studies made it difficult to establish specific contributions of AHWLOs to quality care markers across acute care units. Conclusions The role of AHWLOs in providing quality care in the acute care setting has received minimal research. The limited existing research highlights the importance of the AHWLO role. For example, AHWLOs may influence patient communication, discharge against medical advice and continuity of care within mental health and cardiac care units. Further, because of methodological constraints among the limited studies, research into the role of AHWLOs in these and other acute care settings is needed to assess effects on a range of specific clinical quality markers. What is known about the topic? Aboriginal and Torres Strait Islander people experience unacceptable health inequities. AHWLOs are a unique workforce introduced to increase access to culturally safe care and, ultimately, help to address these inequities. What does this paper add? This review explores the current evidence for the contribution of AHWLOs to quality care in the acute care setting. The findings suggest that these professionals may improve communication between patients and medical staff, improve continuity of care and reduce patient discharge against medical advice. However, these findings highlight that the use of quality care markers across acute care settings is needed to generate tangible evidence to help establish the legitimacy of these health professionals. What are the implications for practitioners? AHWLOs have a place in the acute care team. Although further research is required to expand the preliminary evidence base of their effect on quality acute care, this workforce should be supported at the individual, organisational and policy levels to enhance the health and well-being of one the most vulnerable communities in Australia.

Abstract
We use the Low Frequency Array (LOFAR) to probe the dynamics of the stepping process of negatively charged plasma channels (negative leaders) in a lightning discharge. We observe that at each step of a leader, multiple pulses of vhf (30-80 MHz) radiation are emitted in short-duration bursts (<10 μs). This is evidence for streamer formation during corona flashes that occur with each leader step, which has not been observed before in natural lightning and it could help explain x-ray emission from lightning leaders, as x rays from laboratory leaders tend to be associated with corona flashes. Surprisingly, we find that the stepping length is very similar to what was observed near the ground, however with a stepping time that is considerably larger, which as yet is not understood. These results will help to improve lightning propagation models, and eventually lightning protection models.

Abstract
This paper describes the rationale and process for developing a set of Aboriginal patient journey mapping tools with Aboriginal patients, health professionals, support workers, educators and researchers in the Managing Two Worlds Together project between 2008 and 2015. Aboriginal patients and their families from rural and remote areas, and healthcare providers in urban, rural and remote settings, shared their perceptions of the barriers and enablers to quality care in interviews and focus groups, and individual patient journey case studies were documented. Data were thematically analysed. In the absence of suitable existing tools, a new analytical framework and mapping approach was developed. The utility of the tools in other settings was then tested with health professionals, and the tools were further modified for use in quality improvement in health and education settings in South Australia and the Northern Territory. A central set of patient journey mapping tools with flexible adaptations, a workbook, and five sets of case studies describing how staff adapted and used the tools at different sites are available for wider use.

Abstract
Lightning is a dangerous yet poorly understood natural phenomenon. Lightning forms a network of plasma channels propagating away from the initiation point with both positively and negatively charged ends-called positive and negative leaders1. Negative leaders propagate in discrete steps, emitting copious radio pulses in the 30-300-megahertz frequency band2-8 that can be remotely sensed and imaged with high spatial and temporal resolution9-11. Positive leaders propagate more continuously and thus emit very little high-frequency radiation12. Radio emission from positive leaders has nevertheless been mapped13-15, and exhibits a pattern that is different from that of negative leaders11-13,16,17. Furthermore, it has been inferred that positive leaders can become transiently disconnected from negative leaders9,12,16,18-20, which may lead to current pulses that both reconnect positive leaders to negative leaders11,16,17,20-22 and cause multiple cloud-to-ground lightning events1. The disconnection process is thought to be due to negative differential resistance18, but this does not explain why the disconnections form primarily on positive leaders22, or why the current in cloud-to-ground lightning never goes to zero23. Indeed, it is still not understood how positive leaders emit radio-frequency radiation or why they behave differently from negative leaders. Here we report three-dimensional radio interferometric observations of lightning over the Netherlands with unprecedented spatiotemporal resolution. We find small plasma structures-which we call 'needles'-that are the dominant source of radio emission from the positive leaders. These structures appear to drain charge from the leader, and are probably the reason why positive leaders disconnect from negative ones, and why cloud-to-ground lightning connects to the ground multiple times.

Abstract
Objective Over past decades, Australian and Canadian Indigenous primary healthcare policies have focused on supporting community controlled Indigenous health organisations. After more than 20 years of sustained effort, over 89% of eligible communities in Canada are currently engaged in the planning, management and provision of community controlled health services. In Australia, policy commitment to community control has also been in place for more than 25 years, but implementation has been complicated by unrealistic timelines, underdeveloped change management processes, inflexible funding agreements and distrust. This paper discusses the lessons from the Canadian experience to inform the continuing efforts to achieve the implementation of community control in Australia. Methods We reviewed Canadian policy and evaluation grey literature documents, and assessed lessons and recommendations for relevance to the Australian context. Results Our analysis yielded three broad lessons. First, implementing community control takes time. It took Canada 20 years to achieve 89% implementation. To succeed, Australia will need to make a firm long term commitment to this objective. Second, implementing community control is complex. Communities require adequate resources to support change management. And third, accountability frameworks must be tailored to the Indigenous primary health care context to be meaningful. Conclusions We conclude that although the Canadian experience is based on a different context, the processes and tools created to implement community control in Canada can help inform the Australian context. What is known about the topic? Although Australia has promoted Indigenous control over primary healthcare (PHC) services, implementation remains incomplete. Enduring barriers to the transfer of PHC services to community control have not been addressed in the largely sporadic attention to this challenge to date, despite significant recent efforts in some jurisdictions. What does this paper add? The Canadian experience indicates that transferring PHC from government to community ownership requires sustained commitment, adequate resourcing of the change process and the development of a meaningful accountability framework tailored to the sector. What are the implications for practitioners? Policy makers in Australia will need to attend to reform in contractual arrangements (towards pooled or bundled funding), adopt a long-term vision for transfer and find ways to harmonise the roles of federal and state governments. The arrangements achieved in some communities in the Australian Coordinated Care Trials (and still in place) provide a model.

Abstract
Antiviral therapy for hepatitis B is effective and reduces the risk of progression to cirrhosis and liver cancer but is often required for an indefinite duration. Treatment adherence is important to prevent the development of resistance and optimize outcomes. Pharmacy adherence measures can be used to assess treatment adherence, with the medication possession ratio being less susceptible to bias than physician- or self-reported adherence. The aim of this study was to measure adherence in public hospital outpatients over a 3-year period and to examine factors associated with nonadherence. A retrospective study of pharmacy records of patients dispensed antiviral therapy for hepatitis B from four major hospitals in Melbourne between 2010 and 2013. Hospital record numbers were linked with and de-identified demographic information including age, sex, Indigenous status, country of birth, interpreter requirement, spoken language and postcode of residence. The medication possession ratio was the outcome measure with poor adherence defined <.90. Univariate logistic regression and multivariate logistic regression were performed to examine associations with nonadherence. Records of 1026 patients were included in the analysis. Twenty per cent of all participants met the definition of poor adherence. Significant factors affecting adherence included age <35 years (P=.002), hospital site and treatment by multiple doctors within shorter time periods. This is the largest study examining detailed factors associated with adherence to hepatitis B treatment. Understanding poor adherence in clinical settings, and the factors associated with lower adherence, is important to inform efforts towards promoting treatment adherence for hepatitis B.

Abstract
Problem and its context: Indigenous peoples in many countries suffer poorer health and poorer access to good healthcare than their non-Indigenous counterparts. In Australia, enduring barriers to good health and good healthcare remain, in spite of long-standing policy priorities. These barriers include the ongoing reality of colonisation, and silence about its implications. People working in and using the health system need to relate across cultures, but they approach this endeavour witha complex mixture of goodwill, defensiveness, guilt and anxiety.
Methods: We analysed what is known in Australia about differentials in access to good care, and the underlying factors that entrench them, as well as strategies for developing mainstream competence in care for Aboriginal and Torres Strait Islander patients and communities.
Analysis and Conclusions: The available evidence of differentials in access and quality that are not explained by clinical or demographic variables is unequivocal. Official policy needs to be implemented at the system and organisation level through operational policies, programs and protocols, and through relationships with Aboriginal healthcare providers and community organisations. The concept of racism anxiety provides a way of making one important barrier visible, and moving beyond it can enable people of goodwill to ‘see’ where change is needed, and to see themselves as part of the solution. It is time to get beyond the barriers and attend to practical improvements in care, focused on the care system, not simply on the skills and knowledge of individuals within it.

Abstract
Over the past decades, Indigenous communities around the world have become more vocal and mobilized to address the health inequities they experience. Many Indigenous communities we work with in Canada, Australia, Latin America, the USA, New Zealand and to a lesser extent Scandinavia have developed their own culturally-informed services, focusing on the needs of their own community members. This paper discusses Indigenous healthcare innovations from an international perspective, and showcases Indigenous health system innovations that emerged in Canada (the First Nation Health Authority) and Colombia (Anas Wayúu). These case studies serve as examples of Indigenous-led innovations that might serve as models to other communities. The analysis we present suggests that when opportunities arise, Indigenous communities can and will mobilize to develop Indigenous-led primary healthcare services that are well managed and effective at addressing health inequities. Sustainable funding and supportive policy frameworks that are harmonized across international, national and local levels are required for these organizations to achieve their full potential. In conclusion, this paper demonstrates the value of supporting Indigenous health system innovations.

Abstract
OBJECTIVE This study described the challenges for rural and remote Aboriginal people requiring transport to city hospitals for tertiary care. DESIGN Semi-structured qualitative interviews. SETTING South Australian rural and remote health services and tertiary hospitals. PARTICIPANTS Twenty-eight urban health professionals from six hospitals and 32 health professionals from four rural and remote regions were interviewed. Twelve patients, three carers, four people responding as patient and carers, and one patient and carer couple were also interviewed, with eight elder women meeting as a focus group. MAIN OUTCOME MEASURES The study identified specific structural barriers in urban health services or policy that prevented rural and remote Indigenous patients from receiving optimum care. RESULTS Problems accessing transport were identified as the most significant factor affecting access to care by the majority of patients and staff. They reported that travel to an urban hospital was costly, and coordination of travel with care was poor. A further problem was travelling while unwell. CONCLUSIONS Travelling to a city hospital is a significant barrier for rural and remote Indigenous patients. Arranging and supporting travel is a time-consuming work that is not recognised by the health care system.

Abstract
Alzheimer's disease (AD) drug development is costly, time-consuming, and inefficient. Trial site functions, trial design, and patient recruitment for trials all require improvement. The Global Alzheimer Platform (GAP) was initiated in response to these challenges. Four GAP work streams evolved in the US to address different trial challenges: 1) registry-to-cohort web-based recruitment; 2) clinical trial site activation and site network construction (GAP-NET); 3) adaptive proof-of-concept clinical trial design; and 4) finance and fund raising. GAP-NET proposes to establish a standardized network of continuously funded trial sites that are highly qualified to perform trials (with established clinical, biomarker, imaging capability; certified raters; sophisticated management system. GAP-NET will conduct trials for academic and biopharma industry partners using standardized instrument versions and administration. Collaboration with the Innovative Medicines Initiative (IMI) European Prevention of Alzheimer's Disease (EPAD) program, the Canadian Consortium on Neurodegeneration in Aging (CCNA) and other similar international initiatives will allow conduct of global trials. GAP-NET aims to increase trial efficiency and quality, decrease trial redundancy, accelerate cohort development and trial recruitment, and decrease trial costs. The value proposition for sites includes stable funding and uniform training and trial execution; the value to trial sponsors is decreased trial costs, reduced time to execute trials, and enhanced data quality. The value for patients and society is the more rapid availability of new treatments for AD.

Abstract
OBJECTIVES The need to improve access to good health care for Aboriginal and Torres Strait Islander people has been the subject of policy debate for decades, but progress is hampered by complex policy and administrative arrangements and lack of clarity about the responsibilities of governments. This study aimed to identify the current legal basis of those responsibilities and define options available to Australian governments to enact enduring responsibility for Aboriginal health care. METHODS This study used a framework for public health law research and conducted a mapping study to examine the current legal underpinnings for stewardship and governance for Aboriginal health and health care. More than 200 pieces of health legislation were analysed in the context of the common and statutory law and health policy goals. RESULTS Very little specific recognition of the needs of Aboriginal people was found, and nothing that creates responsibility for stewardship and governance. The continuing absence of a legislative framework to address and protect Aboriginal health can be traced back to the founding doctrine of terra nullius (unoccupied land). CONCLUSIONS We considered the results applying both a human rights perspective and the perspective of therapeutic jurisprudence. We suggest that national law for health stewardship would provide a strong foundation for progress, and should itself be based on recognition of Australia's First Peoples in the Australian Constitution, as is currently proposed.

Abstract
This paper reports on an evaluation of a national action learning set for health policy managers from three Australian state/territory health authorities, conducted during 2010–2011. We collected and analysed qualitative data about the major problems the participants encountered in their work, their experiences of the learning set and their perceptions of the outcomes. The predominant concerns of participants were ‘wicked problems’ in four areas: managing the environment, managing the policy process, managing the self and managing the policy team. Participants reported that the learning set had assisted them to gain greater awareness of and ability to navigate their environment, developed their judgement, strategic and problem-solving skills, contributed to empowerment and self-efficacy, and assisted them in providing support for their staff and building capacity in their organisation. Aspects of the method that contributed to learning included engaging with problems experienced by other members and discussing one’s own problems and strategies; and gaining new insight into ways of framing, analysing and responding to problems. The findings suggest that learning sets can be a powerful method for building policy capacity amongst middle-senior policy managers.

Abstract
AIMS To develop and validate a model to simulate progression of diabetic kidney disease (DKD) from early onset until end-stage renal disease (ESRD), and to assess the effect of renin-angiotensin system (RAS) intervention in early, intermediate and advanced stages of DKD. METHODS We used data from the BENEDICT, IRMA-2, RENAAL and IDNT trials that assessed effects of RAS intervention in patients with type 2 diabetes. We built a model with discrete disease stages based on albuminuria and estimated glomerular filtration rate (eGFR). Using survival analyses, we assessed the effect of RAS intervention on delaying ESRD in early [eGFR>60 ml/min/1.73 m(2) and albumin:creatinine ratio (ACR) <30 mg/g], intermediate (eGFR 30-60 ml/min/1.73 m(2) or ACR 30-300 mg/g) and advanced (eGFR <30 ml/min/1.73 m(2) or ACR >300 mg/g) stages of DKD for patients in different age groups. RESULTS For patients at early, intermediate and advanced stage of disease, whose mean age was 60 years and who received placebo, the median time to ESRD was 21.4, 10.8 and 4.7 years, respectively. RAS intervention delayed the predicted time to ESRD by 4.2, 3.6 and 1.4 years, respectively. The benefit of early RAS intervention was more pronounced in younger patients; for example, for patients with a mean age of 45 years, RAS intervention at early, intermediate or advanced stage delayed ESRD by 5.9, 4.0 and 1.1 years versus placebo. CONCLUSIONS RAS intervention early in the course of proteinuric DKD is more beneficial than late intervention in delaying ESRD.

Abstract
Objective To investigate how policy requiring cultural respect and attention to health equity is implemented in the care of rural and remote Aboriginal people in city hospitals. Methods Interviews with 26 staff in public hospitals in Adelaide, South Australia, were analysed (using a framework based on cultural competence) to identify their perceptions of the enabling strategies and systemic barriers against the implementation of official policy in the care of rural Aboriginal patients. Results The major underlying barriers were lack of knowledge and skills among staff generally, and the persistent use of ‘business as usual’ approaches in their hospitals, despite the clear need for proactive responses to the complex care journeys these patients undertake. Staff reported a sense that while they are required to provide responsive care, care systems often fail to authorise or guide necessary action to enable equitable care. Conclusions Staff caring for rural Aboriginal patients are required to respond to complex particular needs in the absence of effective authorisation. We suggest that systemic misinterpretation of the principle of equal treatment is an important barrier against the development of culturally competent organisations. What is known about this topic? The care received by Aboriginal patients is less effective than it is for the population generally, and access to care is poorer. Those in rural and remote settings experience both severe access barriers and predictable complexity in their patient care journeys. This situation persists despite high-level policies that require tailored responses to the particular needs of Aboriginal people. What does this paper add? Staff who care for these patients develop skills and modify care delivery to respond to their particular needs, but they do so in the absence of systematic policies, procedures and programs that would ‘build in’ or authorise the required responsiveness. What are the implications for practitioners? Systematic attention, at hospital and clinical unit level, to operationalising high policy goals is needed. The framework of cultural competence offers relevant guidance for efforts (at system, organisation and care delivery levels) to improve care, but requires organisations to address misinterpretation of the principle of equal treatment.

Abstract
Kaposi sarcoma (KS) and primary effusion lymphoma (PEL) are two pathologies associated with KS herpes virus (KSHV/HHV-8) infection. KSHV genome contains several oncogenes, among which, the viral G-protein-coupled receptor (vGPCR open reading frame 74) has emerged as a major factor in KS pathogenicity. Indeed, vGPCR is a constitutively active receptor, whose expression is sufficient to drive cell transformation in vitro and tumour development in mice. However, neither the role of vGPCR in KSHV-infected B-lymphocytes nor the molecular basis for its constitutive activation is well understood. Here, we show that vGPCR expression contributes to nuclear factor-κB (NF-κB)-dependent cellular survival in both PEL cells and primary B cells from HIV-negative KS patients. We further identified within vGPCR an AP2 consensus binding motif, Y326GLF, that directs its localization between the plasma membrane and clathrin-coated vesicles. The introduction of a mutation in this site (Y326A) increased NF-κB activity and proinflammatory cytokines production. This correlated with exacerbated morphological rearrangement, migration and proliferation of non-infected monocytes. Collectively, our work raises the possibility that KSHV-infected B-lymphocytes use vGPCR to impact ultimately the immune response and communication within the tumour microenvironment in KSHV-associated pathologies.

Abstract
Gynaecological cancers are the fourth most common form of cancer and the fifth most common cause of cancer mortality for women in Australia. Definitive treatment is available in tertiary hospitals in major capital cities. This study aimed to understand how care is received by women in order to improve both their experience and outcomes. We interviewed 25 women treated for ovarian, cervical and uterine cancers in public or private hospitals in four states, including urban, rural and Indigenous women. Referral pathways were efficient and effective; the women were diagnosed and referred for definitive management through well-established systems. They appreciated the quality of treatment and the care they received during the inpatient and acute phases of their care. Three main problems were identified - serious post-operative morbidity that caused additional pain and suffering, lack of coordination between the surgical team and general practitioners, and poor pain management. The lack of continuity between the acute and primary care settings and inadequate management of pain are acknowledged problems in health care. The extent of post-operative morbidity was not anticipated. Establishing links between the surgical team and primary care in the immediate post-operative period is crucial for the improvement of care for women with gynaecological cancer in Australia.

Abstract
OBJECTIVES To report on differences in Indigenous women's expectations of clinical care during treatment for a gynaecological cancer in rural and remote regions. DESIGN Qualitative interviews were conducted in New South Wales, Victoria, South Australia and the Northern Territory in 2008 with 37 clinicians working in gynaecological cancer and 24 women with a gynaecological cancer. Three of the participants were Indigenous women living in large rural towns (others were non-Indigenous), whereas six of the 37 clinicians interviewed worked closely with Indigenous women in remote settings. Indigenous women were contacted through an Indigenous researcher. Interviews were analysed for emerging themes, then compared with each other and with the research literature for similarities and differences. RESULTS There is considerable variation between clinician observations of the expectations of Indigenous women in remote regions, and the views of Aboriginal women in rural settings. CONCLUSION Indigenous women in rural settings have specific views about quality medical care. These include expectations of timely and culturally appropriate care, and strong ties to family and kin, but do not accord with other research findings that suggest Aboriginal women must receive care from same sex clinicians or that care is often delayed. The paper alerts practitioners to the fact that culturally appropriate care will vary from group to group, particularly between remote, rural and urban populations.

Abstract
Contracting in health care is a mechanism used by the governments of Canada, Australia and New Zealand to improve the participation of marginalized populations in primary health care and improve responsiveness to local needs. As a result, complex contractual environments have emerged. The literature on contracting in health has tended to focus on the pros and cons of classical versus relational contracts from the funder's perspective. This article proposes an analytical framework to explore the strengths and weaknesses of contractual environments that depend on a number of classical contracts, a single relational contract or a mix of the two. Examples from indigenous contracting environments are used to inform the elaboration of the framework. Results show that contractual environments that rely on a multiplicity of specific contracts are administratively onerous, while constraining opportunities for local responsiveness. Contractual environments dominated by a single relational contract produce a more flexible and administratively streamlined system.

Abstract
We report on an all-sky search with the LIGO detectors for periodic gravitational waves in the frequency range 50-1100 Hz and with the frequency's time derivative in the range -5 x 10{-9}-0 Hz s{-1}. Data from the first eight months of the fifth LIGO science run (S5) have been used in this search, which is based on a semicoherent method (PowerFlux) of summing strain power. Observing no evidence of periodic gravitational radiation, we report 95% confidence-level upper limits on radiation emitted by any unknown isolated rotating neutron stars within the search range. Strain limits below 10{-24} are obtained over a 200-Hz band, and the sensitivity improvement over previous searches increases the spatial volume sampled by an average factor of about 100 over the entire search band. For a neutron star with nominal equatorial ellipticity of 10{-6}, the search is sensitive to distances as great as 500 pc.

Abstract
We report on an all-sky search with the LIGO detectors for periodic gravitational waves in the frequency range 50-1100 Hz and with the frequency's time derivative in the range -5 x 10{-9}-0 Hz s{-1}. Data from the first eight months of the fifth LIGO science run (S5) have been used in this search, which is based on a semicoherent method (PowerFlux) of summing strain power. Observing no evidence of periodic gravitational radiation, we report 95% confidence-level upper limits on radiation emitted by any unknown isolated rotating neutron stars within the search range. Strain limits below 10{-24} are obtained over a 200-Hz band, and the sensitivity improvement over previous searches increases the spatial volume sampled by an average factor of about 100 over the entire search band. For a neutron star with nominal equatorial ellipticity of 10{-6}, the search is sensitive to distances as great as 500 pc.

Abstract
We report on an all-sky search with the LIGO detectors for periodic gravitational waves in the frequency range 50-1100 Hz and with the frequency's time derivative in the range -5 x 10{-9}-0 Hz s{-1}. Data from the first eight months of the fifth LIGO science run (S5) have been used in this search, which is based on a semicoherent method (PowerFlux) of summing strain power. Observing no evidence of periodic gravitational radiation, we report 95% confidence-level upper limits on radiation emitted by any unknown isolated rotating neutron stars within the search range. Strain limits below 10{-24} are obtained over a 200-Hz band, and the sensitivity improvement over previous searches increases the spatial volume sampled by an average factor of about 100 over the entire search band. For a neutron star with nominal equatorial ellipticity of 10{-6}, the search is sensitive to distances as great as 500 pc.
