South Australian Allied Health Rural Generalist Pathway Evaluation: Phase 1 Report
© 2020 Flinders UniversityIn 2019 Rural Health Workforce Strategy funding, provided by the Government of South Australia, supported the introduction of the Allied Health Rural Generalist Pathway (AHRGP) as a strategy for improving allied health workforce and quality outcomes for rural and remote South Australians. This pathway was originally developed through a collaboration between the Allied Health Professions Office of Queensland, Services for Rural and Remote Allied Health (SARRAH), Australian state and territory healthcare sectors, and other stakeholders including universities and the Australian Healthcare and Hospitals Association. The education component of the AHRGP is provided by James Cook University in two levels for newly qualified and more experienced Allied Health Professionals (AHPs). Rural generalist trainees enrolled in the program undertake course work and work-based projects throughout the program. They have protected time within their workload to study as well as dedicated profession specific supervision
Observed bodies generate object-based spatial codes
Contemporary studies of spatial and social cognition frequently use human figures as stimuli. The interpretation of such studies may be complicated by spatial compatibility effects that emerge when researchers employ spatial responses, and participants spontaneously code spatial relationships about an observed body. Yet, the nature of these spatial codes â whether they are location- or object-based, and coded from the perspective of the observer or the figure â has not been determined. Here, we investigated this issue by exploring spatial compatibility effects arising for objects held by a visually presented whole-bodied schematic human figure. In three experiments, participants responded to the colour of the object held in the figureâs left or right hand, using left or right key presses. Left-right compatibility effects were found relative to the participantâs egocentric perspective, rather than the figureâs. These effects occurred even when the figure was rotated by 90 degrees to the left or to the right, and the coloured objects were aligned with the participantâs midline. These findings are consistent with spontaneous spatial coding from the participantâs perspective and relative to the normal upright orientation of the body. This evidence for object-based spatial coding implies that the domain general cognitive mechanisms that result in spatial compatibility effects may contribute to certain spatial perspective-taking and social cognition phenomena
Publisher Correction: A PRDX1 mutant allele causes a MMACHC secondary epimutation in cblC patients

A PRDX1 mutant allele causes a MMACHC secondary epimutation in cblC patients
To date, epimutations reported in man have been somatic and erased in germlines. Here, we identify a cause of the autosomal recessive cblC class of inborn errors of vitamin B12 metabolism that we name âepi-cblCâ. The subjects are compound heterozygotes for a genetic mutation and for a promoter epimutation, detected in blood, fibroblasts, and sperm, at the MMACHC locus; 5-azacytidine restores the expression of MMACHC in fibroblasts. MMACHC is flanked by CCDC163P and PRDX1, which are in the opposite orientation. The epimutation is present in three generations and results from PRDX1 mutations that force antisense transcription of MMACHC thereby possibly generating a H3K36me3 mark. The silencing of PRDX1 transcription leads to partial hypomethylation of the epiallele and restores the expression of MMACHC. This example of epi-cblC demonstrates the need to search for compound epigenetic-genetic heterozygosity in patients with typical disease manifestation and genetic heterozygosity in disease-causing genes located in other gene trios
An X-linked cobalamin disorder caused by mutations in transcriptional coregulator HCFC1
Derivatives of vitamin B12 (cobalamin) are essential cofactors for enzymes required in intermediary metabolism. Defects in cobalamin metabolism lead to disorders characterized by the accumulation of methylmalonic acid and/or homocysteine in blood and urine. The most common inborn error of cobalamin metabolism, combined methylmalonic acidemia and hyperhomocysteinemia, cblC type, is caused by mutations in MMACHC. However, several individuals with presumed cblC based on cellular and biochemical analysis do not have mutations in MMACHC. We used exome sequencing to identify the genetic basis of an X-linked form of combined methylmalonic acidemia and hyperhomocysteinemia, designated cblX. A missense mutation in a global transcriptional coregulator, HCFC1, was identified in the index case. Additional male subjects were ascertained through two international diagnostic laboratories, and 13/17 had one of five distinct missense mutations affecting three highly conserved amino acids within the HCFC1 kelch domain. A common phenotype of severe neurological symptoms including intractable epilepsy and profound neurocognitive impairment, along with variable biochemical manifestations, was observed in all affected subjects compared to individuals with early-onset cblC. The severe reduction in MMACHC mRNA and protein within subject fibroblast lines suggested a role for HCFC1 in transcriptional regulation of MMACHC, which was further supported by the identification of consensus HCFC1 binding sites in MMACHC. Furthermore, siRNA-mediated knockdown of HCFC1 expression resulted in the coordinate downregulation of MMACHC mRNA. This X-linked disorder demonstrates a distinct disease mechanism by which transcriptional dysregulation leads to an inborn error of metabolism with a complex clinical phenotype
