Development and implementation of a shared governance model in a mainstream health unit: a case study of embedding Aboriginal voices in organisational decision making.

This case study focuses on the development and implementation of a governance structure and processes by a mainstream health unit that valued the principles of Aboriginal self-determination, empowerment and leadership by Aboriginal staff in organisational and service delivery decisions and elevated Aboriginal voices by embedding cultural inclusion in such decision making. Various models of embedding Aboriginal voices in the governance of the unit were developed and implemented over time. Ongoing review and reflection identified limitations and opportunities for improving the embedding of Aboriginal voices in organisational decision making. In 2017, Aboriginal staff and senior management implemented a joint governance model for providing strategic leadership of the unit with the objective of enhancing the delivery of culturally appropriate population health services for the benefit of Aboriginal communities. In its 3 years of operation to date, the model has provided strategic oversight of the organisation, implemented several strategic initiatives, including a cultural assessment process, maintaining and strengthening Aboriginal recruitment, monitoring employment vacancies, establishing a wellbeing leadership group, monitoring budget allocation and developing an Aboriginal data management protocol, and has provided additional professional development opportunities for Aboriginal staff. This case study demonstrates the feasibility, importance and benefits of engaging and embedding Aboriginal voices in the governance of a mainstream health service delivery unit, as well as the need for ongoing reflection and improvement. Further translation of the model to the operational levels of the unit is required. The governance model has the potential to be replicated in a tailored manner in other mainstream health units and organisations delivering services to Aboriginal peoples and communities. What is known about the topic? Aboriginal people continue to experience the poorest health outcomes of any population group in Australia. Closing the gap in Aboriginal health requires Aboriginal people to be active and equal participants in all levels of decision making. Governance of mainstream health organisations is predominantly positioned in the Western medical positivist paradigm, which fails to embed Aboriginal voices in organisational and service delivery decision making. What does this paper add? This case study describes the processes taken and the outcomes achieved thus far by a mainstream health service delivery unit developing and implementing a governance model that embedded Aboriginal perspectives in its decision making. It highlights that through commitment and persistence, as well as acknowledging the challenges of working between two worlds, it is possible to reconstruct existing governance models, allowing respectful and meaningful space for Aboriginal people to co-design and co-share the governance of health service delivery. This case study demonstrates the potential of the cultural governance model to be replicated and applied to other mainstream health service delivery units. What are the implications for practitioners? This case study highlights the need for health services to invest in employing and empowering Aboriginal people to co-develop and co-lead a shared approach to organisational governance through processes that are culturally safe, inclusive and appropriate.

Constructing an ethical framework for priority allocation of pandemic vaccines.

BACKGROUND: Allocation of scarce resources during a pandemic extends to the allocation of vaccines when they eventually become available. We describe a framework for priority vaccine allocation that employed a cross-disciplinary approach, guided by ethical considerations and informed by local risk assessment. METHODS: Published and grey literature was reviewed, and augmented by consultation with key informants, to collate past experience, existing guidelines and emerging strategies for pandemic vaccine deployment. Identified ethical issues and decision-making processes were also included. Concurrently, simulation modelling studies estimated the likely impacts of alternative vaccine allocation approaches. Assembled evidence was presented to a workshop of national experts in pandemic preparedness, vaccine strategy, implementation and ethics. All of this evidence was then used to generate a proposed ethical framework for vaccine priorities best suited to the Australian context. FINDINGS: Published and emerging guidance for priority pandemic vaccine distribution differed widely with respect to strategic objectives, specification of target groups, and explicit discussion of ethical considerations and decision-making processes. Flexibility in response was universally emphasised, informed by real-time assessment of the pandemic impact level, and identification of disproportionately affected groups. Model outputs aided identification of vaccine approaches most likely to achieve overarching goals in pandemics of varying transmissibility and severity. Pandemic response aims deemed most relevant for an Australian framework were: creating and maintaining trust, promoting equity, and reducing harmful outcomes. INTERPRETATION: Defining clear and ethically-defendable objectives for pandemic response in context aids development of flexible and adaptive decision support frameworks and facilitates clear communication and engagement activities.

Priority allocation of pandemic influenza vaccines in Australia - Recommendations of 3 community juries.

BACKGROUND: Pandemic planning has historically been oriented to respond to an influenza virus, with vaccination strategy being a key focus. As the current COVID-19 pandemic plays out, the Australian government is closely monitoring progress towards development of SARS-CoV2 vaccines as a definitive intervention. However, as in any pandemic, initial supply will likely be exceeded by demand due to limited manufacturing output. METHODS: We convened community juries in three Australian locations in 2019 to assess public acceptability and perceived legitimacy of influenza pandemic vaccination distribution strategies. Preparatory work included literature reviews on pandemic vaccine allocation strategies and on vaccine allocation ethics, and simulation modelling studies. We assumed vaccine would be provided to predefined priority groups. Jurors were then asked to recommend one of two strategies for distributing remaining early doses of vaccine: directly vaccinate people at higher risk of adverse outcomes from influenza; or indirectly protect the general population by vaccinating primary school students, who are most likely to spread infection. RESULTS: Thirty-four participants of diverse backgrounds and ages were recruited through random digit dialling and topic-blinded social media advertising. Juries heard evidence and arguments supporting different vaccine distribution strategies, and questioned expert presenters. All three community juries supported prioritising school children for influenza vaccination (aiming for indirect protection), one by 10-2 majority and two by consensus. Justifications included that indirect protection benefits more people and is likely to be more publicly acceptable. CONCLUSIONS: In the context of an influenza pandemic, informed citizens were not opposed to prioritising groups at higher risks of adverse outcomes, but if resources and epidemiological conditions allow, achieving population benefits should be a strategic priority. These insights may inform future SARS-CoV-2 vaccination strategies.

Anticoagulant rodenticides in urban bobcats: exposure, risk factors and potential effects based on a 16-year study.

Anticoagulant rodenticides (ARs) are increasingly recognized as a threat to nontarget wildlife. High exposure to ARs has been documented globally in nontarget predatory species and linked to the high prevalence of an ectoparasitic disease, notoedric mange. In southern California, mange associated with AR exposure has been the proximate cause of a bobcat (Lynx rufus) population decline. We measured AR exposure in bobcats from two areas in southern California, examining seasonal, demographic and spatial risk factors across landscapes including natural and urbanized areas. The long-term study included bobcats sampled over a 16-year period (1997-2012) and a wide geographic area. We sampled blood (N = 206) and liver (N = 172) to examine exposure ante- and post-mortem. We detected high exposure prevalence (89 %, liver; 39 %, blood) and for individuals with paired liver and blood data (N = 64), 92 % were exposed. Moreover, the animals with the most complete sampling were exposed most frequently to three or more compounds. Toxicant exposure was associated with commercial, residential, and agricultural development. Bobcats of both sexes and age classes were found to be at high risk of exposure, and we documented fetal transfer of multiple ARs. We found a strong association between certain levels of exposure (ppm), and between multiple AR exposure events, and notoedric mange. AR exposure was prevalent throughout both regions sampled and throughout the 16-year time period in the long-term study. ARs pose a substantial threat to bobcats, and likely other mammalian and avian predators, living at the urban-wildland interface.

Frequent transmission of immunodeficiency viruses among bobcats and pumas.

With the exception of human immunodeficiency virus (HIV), which emerged in humans after cross-species transmissions of simian immunodeficiency viruses from nonhuman primates, immunodeficiency viruses of the family Lentiviridae represent species-specific viruses that rarely cross species barriers to infect new hosts. Among the Felidae, numerous immunodeficiency-like lentiviruses have been documented, but only a few cross-species transmissions have been recorded, and these have not been perpetuated in the recipient species. Lentivirus seroprevalence was determined for 79 bobcats (Lynx rufus) and 31 pumas (Puma concolor) from well-defined populations in Southern California. Partial genomic sequences were subsequently obtained from 18 and 12 seropositive bobcats and pumas, respectively. Genotypes were analyzed for phylogenic relatedness and genotypic composition among the study set and archived feline lentivirus sequences. This investigation of feline immunodeficiency virus infection in bobcats and pumas of Southern California provides evidence that cross-species infection has occurred frequently among these animals. The data suggest that transmission has occurred in multiple locations and are most consistent with the spread of the virus from bobcats to pumas. Although the ultimate causes remain unknown, these transmission events may occur as a result of puma predation on bobcats, a situation similar to that which fostered transmission of HIV to humans, and likely represent the emergence of a lentivirus with relaxed barriers to cross-species transmission. This unusual observation provides a valuable opportunity to evaluate the ecological, behavioral, and molecular conditions that favor repeated transmissions and persistence of lentivirus between species.

Ectoparasites of the island fox on Santa Cruz Island.

The ectoparasite fauna for island foxes (Urocyon littoralis) on Santa Cruz Island (California, USA) in April (wet season) and September (dry season) 1998 was evaluated. Three taxa of ectoparasites were identified. These were fleas (Pulex irritans), lice (Neotrichodectes mephitidis), and ticks (Ixodes pacificus). Ectoparasite abundances varied seasonally. Typical of insular endemic species, island foxes may be especially vulnerable to the introduction of novel disease organisms and their vectors.

Hematology and serum chemistry of the island fox on Santa Cruz Island.

Serum and hematologic biochemistry values for island foxes (Urocyon littoralis) on Santa Cruz Island (California, USA) in April (wet season) and September (dry season) 1998 were evaluated. Serum chemistry of island foxes generally varied seasonally; 10 (40%) of the 25 serum characteristics were higher in the wet season, and three (12%) of the 25 serum characteristics were higher in the dry season. No hematologic parameters varied between seasons, although some measures varied between sexes. Blood analytes also varied with age; fox pups had higher values than adults for one hematologic and four serum parameters, whereas adult foxes had higher values for five hematologic characteristics. The information on blood chemistry provides baseline data useful in the monitoring of this threatened insular endemic carnivore.

Biosynthesis and immunolocalization of Lewis a-containing N-glycans in the plant cell.

We recently demonstrated the presence of a new asparagine-linked complex glycan on plant glycoproteins that harbors the Lewis a (Lea), or Galbeta(1-3)[Fucalpha(1-4)]GlcNAc, epitope, which in mammalian cells plays an important role in cell-to-cell recognition. Here we show that the monoclonal antibody JIM 84, which is widely used as a Golgi marker in light and electron microscopy of plant cells, is specific for the Lea antigen. This antigen is present on glycoproteins of a number of flowering and non-flowering plants, but is less apparent in the Cruciferae, the family that includes Arabidopsis. Lea-containing oligosaccharides are found in the Golgi apparatus, and our immunocytochemical experiments suggest that it is synthesized in the trans-most part of the Golgi apparatus. Lea epitopes are abundantly present on extracellular glycoproteins, either soluble or membrane bound, but are never observed on vacuolar glycoproteins. Double-labeling experiments suggest that vacuolar glycoproteins do not bypass the late Golgi compartments where Lea is built, and that the absence of the Lea epitope from vacuolar glycoproteins is probably the result of its degradation by glycosidases en route to or after arrival in the vacuole.

Implementing a rural nursing course.

Southern Alberta is essentially a rural Canadian province and therefore an ideal setting for offering a rural-focused nursing course. Considering the need for professional nurse preparation with a rural focus, three schools of nursing in the Province collaborated to launch their first rural nursing course. The authors elaborate on the process of developing the course, then establishing partnerships with rural communities to provide opportunities for a nursing practicum.

Complete ureteral triplication with ectopia.

A case of complete ureteral triplication is reported and a brief review of the literature is presented.

Comparison of the ileal conduit and clean intermittent catheterization for myelomeningocele.

Clean intermittent catheterization has been shown to be a safe and effective means of regular vesical emptying in children with neurogenic bladders secondary to myelomeningocele. The major benefits appear to be the protection of the upper urinary tract, and in many children, improved urinary control. In contrast, the ileal conduit has been shown to produce significant long-term complications; the major one is deterioration of the upper urinary tract. Most children with myelomeningocele begin life with normal kidneys. Our goal of therapy, therefore, is a continent independent child with normal renal function. With proper patient selection, clean intermittent catheterization offers an excellent means of achieving this result in many children; the ileal conduit for permanent urinary diversion in children is outmoded.

Urethral reconstruction in the young female using a perineal pedicle flap.

Five young female patients with a functionally short or absent urethra are described. Two patients had an abnormal urethra related to a congenital malformation (1 female hypospadias, 1 urogenital sinus) and three patients had an absent urethra related to previous surgery. Four of the five patients were totally incontinent of urine. Urethral reconstruction was achieved by tubularizing the mucosa of the vaginal vault and swinging a full thickness pedicle skin flap from the posterior perineum and buttock to cover the urethral repair. In two patients previously diverted, undiversion was made possible. Urinary continence has been achieved in all five patients.

Urethral strictures following transurethral resection of posterior urethral valves.

Dense urethral strictures developed in 3 of 36 patients (8 per cent) following transurethral fulguration of posterior urethral valves. Common potential etiologies include the use of a loop resectoscope, large size of the valves and immediate supravesical diversion. The latter results in a "dry" urethra and the strictures that resulted may be analogous to the stenosis seen following a "dry" ureteral reimplant. Techniques to maintain flow through the urethra after resection and the avoidance of an extensive resection may be helpful in preventing urethral strictures.
