This study takes a retrospective look at the educational experiences of Indigenous health professionals who graduated from The University of Queensland's Indigenous Health Program between 1994 and 2005, to understand the enablers for growing an Indigenous health workforce capable of advancing the health of Indigenous peoples. Drawing on the qualitative accounts of 31 students and 9 staff members, this paper examines the enablers to educational success at this time, juxtaposed against current Indigenising agendas in higher education, of aspiration and capacity building alongside the task of embedding Indigenous knowledges within curricula. We look back not as a call to return to Indigenous-specific cohort courses but rather reconsider both the measures of and strategies for success in Indigenous higher education, within health and beyond, interrogating the ideological assumptions that inform them.

A central strategy in addressing health disparities experienced by Indigenous people has been based on a concern with workforce improvement. In this paper, the Indigenous Australian healthcare workforce literature since 1977 is reviewed and its scope of concern, as being often limited to questions of ‘supply’, is critiqued. The pipeline metaphor, whether used explicitly or implied, regularly focuses attention on closing the gap on Indigenous representation within the health workforce. The exception though is the discourse concerning Indigenous Health Workers (IHWs), where questions concerning the legitimacy of the role continue to abound within a workforce hierarchy where community knowledge, though shown to be crucial to culturally safe health service provision, is trumped by the other health professions whose knowledges and legitimacy are not in question. This contrast exemplifies the need to examine the working of power not just ‘supply’. The pipeline metaphor is disrupted with concerns about a range of other ‘gaps’ – gaps in the recognition of Indigenous knowledges, in organisational structures, in governance and in self-awareness by the health professions of their whiteness. As the health system continues to measure workforce development in terms of pipeline capacity, our study questions what happens beyond the pipeline.

Jeff Ross-Ibarra and colleagues report a population genomic analysis of maize evolution. They analyze genome-wide evidence for selection during the initial domestication of wild maize and during the improvement of landraces to modern inbred breeds. Their findings suggest stronger selection during domestication compared to improvement. Domestication and plant breeding are ongoing 10,000-year-old evolutionary experiments that have radically altered wild species to meet human needs. Maize has undergone a particularly striking transformation. Researchers have sought for decades to identify the genes underlying maize evolution 1 , 2 , but these efforts have been limited in scope. Here, we report a comprehensive assessment of the evolution of modern maize based on the genome-wide resequencing of 75 wild, landrace and improved maize lines 3 . We find evidence of recovery of diversity after domestication, likely introgression from wild relatives, and evidence for stronger selection during domestication than improvement. We identify a number of genes with stronger signals of selection than those previously shown to underlie major morphological changes 4 , 5 . Finally, through transcriptome-wide analysis of gene expression, we find evidence both consistent with removal of cis -acting variation during maize domestication and improvement and suggestive of modern breeding having increased dominance in expression while targeting highly expressed genes.

Rare circulating tumor cells (CTCs) present in the bloodstream of patients with cancer provide a potentially accessible source for detection, characterization, and monitoring of nonhematological cancers. We previously demonstrated the effectiveness of a microfluidic device, the CTC-Chip, in capturing these epithelial cell adhesion molecule (EpCAM)-expressing cells using antibody-coated microposts. Here, we describe a high-throughput microfluidic mixing device, the herringbone-chip, or “HB-Chip,” which provides an enhanced platform for CTC isolation. The HB-Chip design applies passive mixing of blood cells through the generation of microvortices to significantly increase the number of interactions between target CTCs and the antibody-coated chip surface. Efficient cell capture was validated using defined numbers of cancer cells spiked into control blood, and clinical utility was demonstrated in specimens from patients with prostate cancer. CTCs were detected in 14 of 15 (93%) patients with metastatic disease (median = 63 CTCs/mL, mean = 386 ± 238 CTCs/mL), and the tumor-specific TMPRSS2-ERG translocation was readily identified following RNA isolation and RT-PCR analysis. The use of transparent materials allowed for imaging of the captured CTCs using standard clinical histopathological stains, in addition to immunofluorescence-conjugated antibodies. In a subset of patient samples, the low shear design of the HB-Chip revealed microclusters of CTCs, previously unappreciated tumor cell aggregates that may contribute to the hematogenous dissemination of cancer.

In the wake of recent medical developments in small animal practice, curing animals of their illnesses and restoring their health can be realized better than ever before. However, the growing medical possibilities are also leading to an increase in demand for better care for patients suffering from terminal illnesses. Consequently, the field of animal hospice and palliative care has become increasingly available, enabling veterinarians to optimize the quality of life of patients, such as dogs and cats, who no longer have a prospect of full recovery. Using qualitative, semi-structured interviews with 20 small animal veterinarians involved in hospice and palliative care, we investigated the factors that motivate veterinarians to become involved in hospice and palliative care and explored the importance of relationships, communication, time and infrastructure in this area. Findings show that personal experiences with their own pets or during training or work life motivated veterinarians to provide this service. Although veterinarians highlighted the importance of empathetic-driven relationships, they were aware that keeping an emotional distance from the patient and caregiver is significant to provide successful care. Further, veterinarians emphasized their high investment of time that resulted primarily from the increased frequency and provided opportunities to communicate with caregivers. The overall conclusion is that having time for patients and the patients’ caregivers is one of the most important aspects of work in this field. However, as it will be also shown, veterinarians must consider aspects of self-care management by reflecting on their own time and energy resources while caring for animals and their caregivers.
