To explore the factors influencing parents' choice of communication mode during early education of their child with hearing loss. Qualitative descriptive analysis of semi-structured interviews with parents of children with hearing loss. Fourteen parents of children who participated in the Longitudinal Outcomes of Children with Hearing Impairment study. Four themes emerged from thematic analysis of the interview data: (1) parents draw on a variety of experiences and information to make decisions; (2) parents' preferred outcomes for their children drive their choices; (3) child's preference and proficiency drive parental choice; and (4) parents' fears and worries influence decisions. The results reinforced the importance of parents receiving unbiased, descriptive information as well as evaluative information from professionals, so that they could consider all options in making a decision that met their needs. Parents also require continual support for implementation of their choices as they adjust to their children's changing communication needs. Parent decisions around communication mode are rarely made in isolation, but occur within a larger decision-making matrix that include device choices, early intervention agency choices, and 'future-proofing' the child's ongoing communication needs.

Background: Elective surgery cancellations and delays are associated with negative financial and staffing ramifications, adverse clinical outcomes, and poor patient outcomes. The Princess Alexandra Hospital in Brisbane, Australia, performs approximately 15 000 elective surgeries per year and medication optimisation is pivotal in preparing a patient for surgery to avoid same day of surgery theatre cancellations. Ideally, patients are seen in a multidisciplinary pre‐admission clinic for optimisation of their health and medicines, and to provide education regarding their surgery. Aim: To calculate the incidence of elective surgery cancellations due to medication misadventure over a 12‐month period. Method: A retrospective audit at a tertiary Queensland Hospital was conducted over a 12‐month period (April 2021–March 2022), including patients who had their elective surgeries cancelled. The medical records from the hospital's digital databases for patients who were identified by the hospital coding service as 'unfit for surgery' were screened to see if the reason for the surgery cancellation was due to medication misadventure. The project was reviewed by the Metro South Human Research Ethics Committee and deemed exempt from further review (Ref No: CM20221651). Results: The surgery cancellation rate was 50% (n = 6626 cancelled surgeries from 13 255 total surgeries booked). The same day of surgery cancellation rate was 5.5% (n = 734). Medication misadventure resulting from suboptimal medicine management was responsible for 1% (n = 66 out of 6626 surgery cancellations). A total of 41% (n = 27) of patients had their surgery cancelled ahead of time by the pharmacist due to a medication not being withheld for long enough, which prevented a same‐day cancellation. Conclusion: Having a pre‐admission clinic pharmacist improves preoperative medication optimisation and has been proven to avoid same‐day cancellations. [ABSTRACT FROM AUTHOR]

Hearing loss is an etiologically heterogeneous trait with differences in the age of onset, severity and site of lesion. It is caused by a combination of genetic and/or environmental factors. A longitudinal study to examine the efficacy of early intervention for improving child outcomes is ongoing in Australia. To determine the cause of hearing loss in these children we undertook molecular testing of perinatal “Guthrie” blood spots of children whose hearing loss was either detected via newborn hearing screening or detected later in infancy. We analyzed the GJB2 and SLC26A4 genes for the presence of mutations, screened for the mitochondrial DNA (mtDNA) A1555G mutation, and screened for congenital CMV infection in DNA isolated from dried newborn blood spots. Results were obtained from 364 children. We established etiology for 60% of children. One or two known GJB2 mutations were present in 82 children. Twenty-four children had one or two known SLC26A4 mutations. GJB2 or SLC26A4 changes with unknown consequences on hearing were found in 32 children. The A1555G mutation was found in one child, and CMV infection was detected in 28 children. Auditory neuropathy spectrum disorder was confirmed in 26 children whose DNA evaluations were negative. A secondary objective was to investigate the relationship between etiology and audiological outcomes over the first 3 years of life. Regression analysis was used to investigate the relationship between hearing levels and etiology. Data analysis does not support the existence of differential effects of etiology on degree of hearing loss or on progressiveness of hearing loss. [ABSTRACT FROM AUTHOR]

Abstract: Canines are definitive hosts of Neospora caninum (Apicomplexa). For horizontal transmission from canines to occur, viable oocysts of N. caninum must occur in the environment of susceptible intermediate hosts. Canids in Australia include wild dogs and Aboriginal community dogs. Wild dogs are those dogs that are not dependent on humans for survival and consist of the dingo, feral domestic dog and their hybrid genotypes. Aboriginal community dogs are dependent on humans, domesticated and owned by a family, but are free-roaming and have free access throughout the community. In this study the extent of N. caninum infection was determined in a total of 374 dogs (75 wild dogs and 299 Aboriginal community dogs) using a combination of microscopic, molecular and serological techniques. Oocysts of N. caninum were observed in the faeces of two juvenile Aboriginal community dogs (2/132; 1.5%). To estimate N. caninum prevalence, a new optimised cut-off of 18.5% inhibition for a commercial competitive ELISA was calculated using a two-graph receiver-operating characteristic (TG-ROC) analysis and IFAT as the gold standard resulting in equal sensitivity and specificity of 67.8%. Of the 263 dog sera tested the true prevalence of N. caninum antibodies was 27.0% (95% confidence limit: 10.3–44.1%). The association between the competitive ELISA results in dogs less than 12 month old and older dogs was significant (P =0.042). To our knowledge this is the first large scale parasitological survey of the Aboriginal community dogs and wild dogs from Australia. The high prevalence of N. caninum infection in Aboriginal community dogs illustrates that horizontal transmission of N. caninum is occurring in Australia. These results demonstrated that N. caninum in dogs is widespread, including the semi-arid to arid regions of north-western New South Wales and the Northern Territory. The populations of free-ranging dogs are likely to be important contributors to the sylvatic life cycle of N. caninum. [Copyright &y& Elsevier]

Abstract: This study was undertaken to determine the flea diversity on urban dogs and cats in Australia in 2009-2010. A total of 2530 fleas were recovered from 291 animals (151 dogs, 69 cats and 71 uncategorised dogs or cats) from veterinary clinics across five states of Australia. The majority of specimens were from coastal areas. The cat flea (Ctenocephalides felis felis) was the most frequent flea species identified (98.8%, 2500/2530). The only other flea species identified was the stickfast flea (Echidnophaga gallinacea) from Western Australia. Sequencing of the cytochrome oxidase subunit II mtDNA revealed a single haplotype across Australia within a subset of C. f. felis (n =19). Our study demonstrated dominance and haplotype homogeneity of C. f. felis on dogs and cats. Although Ctenocephalides canis was recovered from a feral fox, it was not identified from the sample of fleas analysed. This suggests that, under current conditions, it is unlikely that foxes are reservoirs of C. canis for domestic dogs or cats residing in coastal Australia, as previously speculated.

Neospora caninum is transmitted either transplacentally or horizontally by ingestion of tissue cysts present in tissues or oocysts shed by dogs. Neosporosis is a significant disease, causing cattle abortion at 5-7 months of pregnancy. Infected cows may remain infective for life transmitting the infection in several consecutive or non-consecutive pregnancies. A great deal is known about the epidemiology of neosporosis, although only limited information is available on the main routes of horizontal transmission. In Australia, the presence of the dingo as the top-order predator suggests a potential sylvatic route of transmission between dingoes and as yet unknown native wildlife in addition to the domestic route via dogs with access to infected tissue on farms. This review article critically evaluates the overlap between the domestic and sylvatic mutes, taking into account canine ecology, and summarises current understanding of the transmission of N. caninum to provide a foundation for epidemiologists, farmers and conservation biologists dealing with neosporosis and wild dog control programs.

Abstract: To provide objective data on the potential role of dingoes (Canis lupus dingo) in the life cycle of Neospora caninum in Australia, the production of N. caninum oocysts by experimentally infected canids was investigated. Three dingo pups raised in captivity and three domestic dogs were fed tissue from calves infected with an Australian isolate of N. caninum, Nc-Nowra. Oocysts of N. caninum, confirmed by species-specific PCR, were shed in low numbers by one dingo pup at 12–14days p.i. The remaining animals did not shed oocysts. Furthermore, the blood from two out of three dingoes tested positive for DNA of N. caninum using PCR tests at 14 and 28days p.i. Oocyst shedding from the intestinal tract of a dingo demonstrates that dingoes are definitive hosts of N. caninum and horizontal transmission of N. caninum from dingoes to farm animals and wildlife may occur in Australia.
