Objective Although musculoskeletal disorders (MSD) represent one of the most important occupational health issues in contemporary society, few studies have specifically investigated this problem among veterinarians. Design An anonymous questionnaire survey mailed to all veterinarians registered with the Veterinary Surgeons Board of Queensland during 2006. Results Almost two-thirds of respondents (63%) had experienced MSD of the lower back, 57% had experienced neck-related MSD, 52% had experienced shoulder-related MSD and 34% had experienced MSD of the upper back during the previous 12 months. MSD was statistically correlated with a range of psychosocial factors, including stress associated with career structure, time pressures, client's attitude, lack of recognition by the public, lack of recognition by colleagues, lack of understanding from family or partners and work stress because of insufficient holidays each year. Conclusion Overall, this study has demonstrated significant correlations between MSD and psychosocial risk factors among a large cohort of veterinarians, apparently for the first time in the published literature. The results also suggest that personal and workplace issues may contribute more to the development of MSD among veterinarians than many of the previously recognised ergonomic risk factors.

Background: Percutaneous exposure incidents (PEI) represent an important occupational health issue in dentistry, and one that can incur severe consequences from blood-borne infections. Given the importance of this topic, we considered it necessary to investigate the distribution and cause of PEI among Queensland dentists.Methods: In 2004, a self-reporting questionnaire was mailed to a random sample of 400 dentists on the register of the Queensland Branch of the Australian Dental Association.Results: A total of 285 questionnaires (73.1 per cent) were completed and returned. Of the respondents, 73.3 per cent were male and 26.7 per cent female, with a mean age of 45.2 years (SD = 11.9 years). Most were general dentists (89.1 per cent) with the remainder being specialists (10.9 per cent). More than three-quarters (78.5 per cent) reported damaging their gloves at least once during a clinical procedure in the previous 12-month period. Roughly one-quarter (27.7 per cent) had experienced at least one 'sharps' or needlestick injury in the previous 12 months, 16.1 per cent of which involved a contaminated instrument that had been previously used on a patient. The most common devices to cause 'sharps' injury in the previous 12 months were needles (14.4 per cent) and burs (10.2 per cent).Conclusions: Although PEI clearly remains a major occupational health problem for Queensland dentists, the prevalence of needlestick injuries appears to be lower than other studies from developed countries. The identification of needlestick injuries as a common cause of PEI again stresses the importance of preventive strategies with respect to potential blood-borne infections. Further research is now needed to more carefully identify effective measures for reducing PEI among dental personnel. [ABSTRACT FROM AUTHOR]- Published

SHRIMPS ,PROTEINS ,GLUTAMIC acid - Abstract
The distribution and fate ofC-proline were investigated in immature tiger prawns, Penaeus esculentus Haswell, collected in Moreton Bay, Cleveland, Australia, by trawling during 1986/1987. Initially the prawns were fedC-proline in food pellets to follow the pathway of proline absorption and distribution in the body.C-proline was also injected directly into the prawn to provide sufficient tracer to follow the incorporation ofC into other amino acids and into proteins. A comparison was made of the metabolism of injectedC-proline over 48 h in prawns that had been fed and those that had been starved for 10 d. Free amino acids (FAA) in the muscle and protein-bound amino acids were analysed separately. Labelled proline was completely absorbed and distributed within the body 3 h after ingestion, about 80% being in the tissues, mostly in muscle. There was no significant difference between the total CO output in fed and starved prawns, but the latter metabolised about twice the amount of labelled proline over 48 h. At this time, in abdominal muscle of fed prawns, about 95% of the total muscle label was in the FAA; of the label in the FAA, 78% was proline and 18% glutamic acid, with the remainder in hydroxyproline, aspartic acid, glutamine, alanine and Kreb's cycle intermediates. In the starved prawns, proline was 58%, glutamic acid 24%, with correspondingly higher amounts in the other compounds. In the muscle protein, the distribution of label was similar in fed and starved prawns, with 72 to 74% as proline. The experiments showed that proline is not very labile in the tiger prawn and its rate of synthesis is slow. It does not appear to be an important source of energy as in some insects and cephalopods, but during starvation is only slowly oxidised for energy. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Medical internship is a key transition point in medical training from student to independent (junior) doctor. The national Regional Training Hubs (RTH) policy began across Australia in late 2017, which aims to build medical training pathways for junior doctors within a rural region and guide students, interns and trainees towards these. This study aims to explore preferencing and acceptance trends for rural medical internship positions in Queensland. Moreover, it focuses on internship preference and acceptance outcomes prior to and following the establishment of RTHs, and their association with key covariates such as rural training immersions offered by medical schools., Methods: Data from all applicants to Queensland Health intern positions between 2014-2021 were available, notably their preference order and location of accepted internship position, classified as rural or metropolitan. Matched data from Queensland's medical schools were added for rural training time and other key demographics. Analyses explored the statistical associations between these factors and preferencing or accepting rural internships, comparing pre-RTH and post-RTH cohorts., Results: Domestic Queensland-trained graduates first preferencing rural intern positions increased significantly (pre-RTH 21.1% vs post-RTH 24.0%, p = 0.017), reinforced by a non-significant increase in rural acceptances (27.3% vs 29.7%, p = 0.070). Rural interns were more likely to have previously spent ≥ 11-weeks training in rural locations within medical school, be rurally based in the year applying for internship, or enrolled in the rural generalist pathway., Conclusions: The introduction of the RTH was associated with a moderate increase of graduates both preferencing and accepting a rural internship, though a richer understanding of the dominant reasons for and against this remain less clear. An expansion of graduates who undertook longer periods of undergraduate rural training in the same period did not diminish the proportion choosing a rural internship, suggesting there remains an appetite for these opportunities. Overall, domestic graduates are identified as a reliable source of intern recruitment and retention to rural hospitals across Queensland, with entry to the rural generalist pathway and extended rural placement experiences enhancing uptake of rural practice., (© 2024.

- Abstract
In Australia, disease registers for acute rheumatic fever (ARF) and rheumatic heart disease (RHD) were previously established to facilitate disease surveillance and control, yet little is known about the extent of case-ascertainment. We compared ARF/RHD case ascertainment based on Australian ARF/RHD register records with administrative hospital data from the Northern Territory (NT), South Australia (SA), Queensland (QLD) and Western Australia (WA) for cases 3-59 years of age. Agreement across data sources was compared for persons with an ARF episode or first-ever RHD diagnosis. ARF/RHD registers from the different jurisdictions were missing 26% of Indigenous hospitalised ARF/RHD cases overall (ranging 17-40% by jurisdiction) and 10% of non-Indigenous hospitalised ARF/RHD cases (3-28%). The proportion of hospitalised RHD cases (36%) was half the proportion of hospitalised ARF cases (70%) notified to the ARF/RHD registers. The registers were found to capture few RHD cases in metropolitan areas (SA Metro: 13%, QLD Metro: 35%, WA Metro: 14%). Indigenous status, older age, comorbidities, drug/alcohol abuse and disease severity were predictors of cases appearing in the hospital data only ( p < 0.05); sex was not a determinant. This analysis confirms that there are biases associated with the epidemiological analysis of single sources of case ascertainment for ARF/RHD using Australian data.

- Abstract
Background: Advanced physiotherapist-led services have been embedded in specialist orthopaedic and neurosurgical outpatient departments across Queensland, Australia, to ameliorate capacity constraints. Simulation modelling has been used to inform the optimal scale and professional mix of services required to match patient demand. The context and the value of simulation modelling in service planning remain unclear. We aimed to examine the adoption, context and costs of using simulation modelling recommendations to inform service planning., Methods: Using an implementation science approach, we undertook a prospective, qualitative evaluation to assess the use of discrete event simulation modelling recommendations for service re-design and to explore stakeholder perspectives about the role of simulation modelling in service planning. Five orthopaedic and neurosurgical services in Queensland, Australia, were selected to maximise variation in implementation effectiveness. We used the consolidated framework for implementation research (CFIR) to guide the facilitation and analysis of the stakeholder focus group discussions. We conducted a prospective costing analysis in each service to estimate the costs associated with using simulation modelling to inform service planning., Results: Four of the five services demonstrated adoption by inclusion of modelling recommendations into proposals for service re-design. Four CFIR constructs distinguished and two CFIR constructs did not distinguish between high versus mixed implementation effectiveness. We identified additional constructs that did not map onto CFIR. The mean cost of implementation was AU$34,553 per site (standard deviation = AU$737)., Conclusions: To our knowledge, this is the first time the context of implementing simulation modelling recommendations in a health care setting, using a validated framework, has been examined. Our findings may provide valuable insights to increase the uptake of healthcare modelling recommendations in service planning.

- Abstract
Neuroticism is a personality trait of fundamental importance for psychological well-being and public health. It is strongly associated with major depressive disorder (MDD) and several other psychiatric conditions. Although neuroticism is heritable, attempts to identify the alleles involved in previous studies have been limited by relatively small sample sizes. Here we report a combined meta-analysis of genome-wide association study (GWAS) of neuroticism that includes 91 370 participants from the UK Biobank cohort, 6659 participants from the Generation Scotland: Scottish Family Health Study (GS:SFHS) and 8687 participants from a QIMR (Queensland Institute of Medical Research) Berghofer Medical Research Institute (QIMR) cohort. All participants were assessed using the same neuroticism instrument, the Eysenck Personality Questionnaire-Revised (EPQ-R-S) Short Form's Neuroticism scale. We found a single-nucleotide polymorphism-based heritability estimate for neuroticism of ∼15% (s.e.=0.7%). Meta-analysis identified nine novel loci associated with neuroticism. The strongest evidence for association was at a locus on chromosome 8 (P=1.5 × 10(-15)) spanning 4 Mb and containing at least 36 genes. Other associated loci included interesting candidate genes on chromosome 1 (GRIK3 (glutamate receptor ionotropic kainate 3)), chromosome 4 (KLHL2 (Kelch-like protein 2)), chromosome 17 (CRHR1 (corticotropin-releasing hormone receptor 1) and MAPT (microtubule-associated protein Tau)) and on chromosome 18 (CELF4 (CUGBP elav-like family member 4)). We found no evidence for genetic differences in the common allelic architecture of neuroticism by sex. By comparing our findings with those of the Psychiatric Genetics Consortia, we identified a strong genetic correlation between neuroticism and MDD and a less strong but significant genetic correlation with schizophrenia, although not with bipolar disorder. Polygenic risk scores derived from the primary UK Biobank sample captured ∼1% of the variance in neuroticism in the GS:SFHS and QIMR samples, although most of the genome-wide significant alleles identified within a UK Biobank-only GWAS of neuroticism were not independently replicated within these cohorts. The identification of nine novel neuroticism-associated loci will drive forward future work on the neurobiology of neuroticism and related phenotypes.

- Abstract
Citrus crops are considered to be relatively poor hosts for Queensland fruit fly, Bactrocera tryoni (Froggatt), as for other tephritid species. Australian citrus growers and crop consultants have reported observable differences in susceptibility of different citrus cultivars under commercial growing conditions. In this study we conducted laboratory tests and field surveys to determine susceptibility to B. tryoni of six citrus cultivars [(Eureka lemon (Citrus limon (L.) Osbeck); Navel and Valencia oranges (C. sinensis (L.) Osbeck); and Imperial, Ellendale, and Murcott mandarins (C. reticulata Blanco). The host susceptibility of these citrus cultivars was quantified by a Host Susceptibility Index, which is defined as the number of adult flies produced per gram of fruit infested at a calculated rate of one egg per gram of fruit. The HSI was ranked as Murcott (0.083) > Imperial (0.052) > Navel (0.026) - Ellendale (0.020) > Valencia (0.008) > Eureka (yellow) (0.002) > Eureka (green) (0). Results of the laboratory study were in agreement with the level of field infestation in the four citrus cultivars (Eureka lemon, Imperial, Ellendale, and Murcott mandarins) that were surveyed from commercial orchards under baiting treatments against fruit flies in the Central Burnett district of Queensland. Field surveys of citrus hosts from the habitats not subject to fruit fly management showed that the numbers of fruit flies produced per gram of fruit were much lower, compared with the more susceptible noncitrus hosts, such as guava (Psidium guajava L.), cherry guava (P. littorale Raddi), mulberry (Morus nigra L.), loquat (Eriobotrya japonica (Thunb.) Lindl.), and pear (Pyrus communis L.). Therefore, the major citrus crops commercially cultivated in Australia have a relatively low susceptibility to B. tryoni, with Eureka lemons being a particularly poor host for this tephritid fruit fly.

- Abstract
The results of a tobacco smoking survey conducted among veterinarians in Queensland, Australia, during 2007 are presented. Of the 567 participants only 3% reported being current smokers, 24% were ex-smokers and 73% had never smoked. The prevalence of smoking was similar among males and females, and the highest smoking rate was reported among veterinarians aged 31-40 years. However, the rate of never-smokers was strongly and negatively correlated with age, and the proportion of ex-smokers increased with age. Encouragingly, the results from this study suggest that tobacco use has all but disappeared from the Australian veterinary profession in recent years.

- Abstract
Background: Musculoskeletal disorders (MSD) represent an important occupational health issue in dentistry. Given the significance of this topic, we considered it necessary to investigate the prevalence and impact of MSD among Australian dentists., Methods: In 2004, a self-reporting questionnaire was mailed to a random sample of 400 dentists registered with the Queensland Branch of the Australian Dental Association., Results: A total of 285 questionnaires (73.1 per cent) were completed and returned. Of the respondents, 73.3 per cent were male and 26.7 per cent female, with a mean age of 45.2 years (SD = 11.9 years). Most were general dentists (89.1 per cent), with the remainder being specialists (10.9 per cent). Most dentists (87.2 per cent) reported having experienced at least one MSD symptom in the past 12 months. The most prevalent MSD during the previous 12 months were reported at the neck (57.5 per cent), lower back (53.7 per cent) and shoulder (53.3 per cent). MSD which interfered with daily activities during the previous 12 months were reported at the neck (24.6 per cent), the lower back (22.1 per cent) and the shoulders (21.8 per cent). Over one-third (37.5 per cent) of dentists had sought medical advice or treatment for an MSD during the previous 12-month period. Almost 1 in 10 dentists (9.1 per cent) reported taking leave in the previous 12 months because of an MSD. Among those who took sick leave for an MSD, the mean time taken was 11.5 days (SD = 16.0 days)., Conclusions: Overall, this study suggests that MSD represents a major occupational health issue for Queensland dentists, the occurrence of which is similar to reports from other countries. MSD was shown to interfere with daily activities in some cases, while a considerable proportion of dentists had also sought medical attention for their symptoms. Further research is now needed to more carefully elucidate the impact of MSD in this particular occupational group, especially in relation to cessation or reduction of clinical practice, and also to help identify specific risk factors and effective measures for reducing MSD among dentists in Queensland and elsewhere.
