    Full Text Available Abstract Background There is some concern that coal seam gas mining may affect health and wellbeing through changes in social determinants such as living and working conditions, local economy and the environment. The onward impact of these conditions on health and wellbeing is often not monitored to the same degree as direct environmental health impacts in the mining context, but merits attention. This study reports on the findings from a recurrent theme that emerged from analysis of the qualitative component of a comprehensive Health Needs Assessment (HNA conducted in regional Queensland: that health and wellbeing of communities was reportedly affected by nearby coal seam gas (CSG development beyond direct environmental impacts. Methods Qualitative analysis was initially completed using the Framework Method to explore key themes from 11 focus group discussions, 19 in-depth interviews, and 45 key informant interviews with health and wellbeing service providers and community members. A key theme emerged from the analysis that forms the basis of this paper. This study is part of a larger comprehensive HNA involving qualitative and quantitative data collection to explore the health and wellbeing needs of three communities living in proximity to CSG development in regional Queensland, Australia. Results Communities faced social, economic and environmental impacts from the rapid growth of CSG development, which were perceived to have direct and indirect effects on individual lifestyle factors such as alcohol and drug abuse, family relationships, social capital and mental health; and community-level factors including social connectedness, civic engagement and trust. Conclusions Outer regional communities discussed the effects of mining activity on the fabric of their town and community, whereas the inner regional community that had a longer history of industrial activity discussed the impacts on families and individual health and wellbeing.

    Objective To determine trends in the incidence of foot-related hospitalisation and amputation amongst persons with diabetes in Queensland (Australia) between 2005 and 2010 that coincided with changes in state-wide ambulatory diabetic foot-related complication management. Methods All data from cases admitted for the principal reason of diabetes foot-related hospitalisation or amputation in Queensland from 2005–2010 were obtained from the Queensland Hospital Admitted Patient Data Collection dataset. Incidence rates for foot-related hospitalisation (admissions, bed days used) and amputation (total, minor, major) cases amongst persons with diabetes were calculated per 1,000 person-years with diabetes (diabetes population) and per 100,000 person-years (general population). Age-sex standardised incidence and age-sex adjusted Poisson regression models were also calculated for the general population. Results There were 4,443 amputations, 24,917 hospital admissions and 260,085 bed days used for diabetes foot-related complications in Queensland. Incidence per 1,000 person-years with diabetes decreased from 2005 to 2010: 43.0% for hospital admissions (36.6 to 20.9), 40.1% bed days (391 to 234), 40.0% total amputations (6.47 to 3.88), 45.0% major amputations (2.18 to 1.20), 37.5% minor amputations (4.29 to 2.68) (p amputations (18.57 to 14.99), 26.4% major amputations (6.26 to 4.61), 15.7% minor amputations (12.32 to 10.38) (p amputations 0.962 (0.946–0.979), major amputations 0.945 (0.917–0.974), minor amputations 0.970 (0.950–0.991) (p amputation amongst persons with diabetes in the population of Queensland over a recent six-year period.

    The practice of proximal formative assessment - the continual, responsive attention to students' developing understanding as it is expressed in real time - depends on students' sharing their ideas with instructors and on teachers' attending to them. Rogerian psychology presents an account of the conditions under which proximal formative assessment may be promoted or inhibited: (1) Normal classroom conditions, characterized by evaluation and attention to learning targets, may present threats to students' sense of their own competence and value, causing them to conceal their ideas and reducing the potential for proximal formative assessment. (2) In contrast, discourse patterns characterized by positive anticipation and attention to learner ideas increase the potential for proximal formative assessment and promote self-directed learning. We present an analysis methodology based on these principles and demonstrate its utility for understanding episodes of university physics instruction.

    Full Text Available Abstract Background Alcohol-related harm is a substantial burden on the community in Australia and internationally, particularly harm related to risky drinking practices of young people in the night-time economy. This protocol paper describes a study that will report on the changes in a wide range of health and justice outcome measures associated with major policy changes in the state of Queensland, Australia. A key element includes trading hours restrictions for licensed premises to 2 am for the state and 3 am in Safe Night Precincts (SNPs. Other measures introduced include drinks restrictions after midnight, increased patron banning measures for repeat offenders, mandatory ID scanning of patrons in late-night venues, and education campaigns. Methods The primary aim of the study is to evaluate change in the levels of harm due to these policy changes using administrative data (e.g., police, hospital, ambulance, and court data. Other study elements will investigate the impact of the Policy by measuring foot traffic volume in SNPs, using ID scanner data to quantify the volume of people entering venues and measure the effectiveness of banning notices, using patron interviews to quantify the levels of pre-drinking, intoxication and illicit drug use within night-time economy districts, and to explore the impacts of the Policy on business and live music, and costs to the community. Discussion The information gathered through this project aims to evaluate the effectiveness of the Policy and to draw on these findings to inform future prevention and enforcement approaches by policy makers, police, and venue staff.

    Several trends that affect the manufacturing of sophisticated goods - increasing international fragmentation of production, and lean and modular process technologies - have increased the importance of proximity in the supply chain. We use the case of the European automotive industry to simultaneously evaluate the relative importance of three dimensions: geographical, cultural, and relational proximity. Using a rich and novel data set, we find that carmakers value some aspects of each dimensio...

The importance of the identity of the interloper, however, has been neglected. We explored the influence of relational proximity (i.e., the degree of genetic relatedness on distress about infidelity. In Study 1, participants were most distressed when the imagined infidelity occurred between their current mate and close kin. In Study 2, relational proximity mattered more than the type of sexual behavior, the likelihood of contracting a sexually transmitted disease, and the likelihood of the infidelity leading to a damaged reputation. Together, the results indicate that identity matters, especially if the interloper is someone with whom we have familial bonds.

    We study the question of how reliably one can distinguish two quantum field theories (QFTs). Each QFT defines a probability distribution on the space of fields. The relative entropy provides a notion of proximity between these distributions and quantifies the number of measurements required to distinguish between them. In the case of nearby conformal field theories, this reduces to the Zamolodchikov metric on the space of couplings. Our formulation quantifies the information lost under renormalization group flow from the UV to the IR and leads us to a quantification of fine-tuning. This formalism also leads us to a criterion for distinguishability of low energy effective field theories generated by the string theory landscape.

    In 2011, Queensland dialysis services experienced two unprecedented natural disasters within weeks of each other. Floods in south-east Queensland and Tropical Cyclone Yasi in North Queensland caused widespread flooding, property damage and affected the provision of dialysis services, leading to Australia's largest evacuation of dialysis patients. This paper details the responses to the disasters and examines what worked and what lessons were learnt. Recommendations are made for dialysis units in relation to disaster preparedness, response and recovery. © 2012 The Authors. Nephrology © 2012 Asian Pacific Society of Nephrology.

    Full Text Available Let A, B be nonempty closed bounded convex subsets of a uniformly convex Banach space and T : A∪B → A∪B be a map such that T(A ⊆ B, T(B ⊆ A and ǁTx − Tyǁ ≤ ǁx − yǁ, for x in A and y in B. The fixed point equation Tx = x does not possess a solution when A ∩ B = Ø. In such a situation it is natural to explore to find an element x0 in A satisfying ǁx0 − Tx0ǁ = inf{ǁa − bǁ : a ∈ A, b ∈ B} = dist(A,B. Using Zorn’s lemma, Eldred et.al proved that such a point x0 exists in a uniformly convex Banach space settings under the conditions stated above. In this paper, by using a convergence theorem we attempt to prove the existence of such a point x0 (called best proximity point without invoking Zorn’s lemma.

    Throughout human history, social groups have invested immense amounts of wealth and time to keep threatening out-groups at a distance. In the current research, we explored the relationship between intergroup threat, physical distance, and discrimination. Specifically, we examined how intergroup threat alters estimates of physical distance to out-groups and how physical proximity affects intergroup relations. Previous research has found that people judge threatening out-groups as physically close. In Studies 1 and 2, we examined ways to attenuate this bias. In Study 1 a secure (vs. permeable) US-Mexico border reduced the estimated proximity to Mexico City among Americans who felt threatened by Mexican immigration. In Study 2, intergroup apologies reduced estimates of physical proximity to a threatening cross-town rival university, but only among participants with cross-group friendships. In Study 3, New York Yankees fans who received an experimental induction of physical proximity to a threatening out-group (Boston Red Sox) had a stronger relationship between their collective identification with the New York Yankees and support for discriminatory policies toward members of the out-group (Red Sox fans) as well as how far they chose to sit from out-group members (Red Sox fans). Together, these studies suggest that intergroup threat alters judgment of physical properties, which has important implications for intergroup relations. PMID:27467267

  17. Existential neuroscience: neurophysiological correlates of proximal defenses against death-related thoughts

    2013-01-01

    A great deal of evidence suggests that reminders of mortality increase ingroup support and worldview defense, presumably in order to deal with the potential for anxiety that roots in the knowledge that death is inevitable. Interestingly, these effects are obtained solely when thoughts of death are not in the focus of consciousness. When conscious, death-related thoughts are usually defended against using proximal defenses, which entail distraction or suppression. The present study aimed at demonstrating neurophysiological correlates of proximal defenses. We focused on the late positive potential (LPP), which is thought to reflect an increased allocation of attention toward, and processing of, motivationally relevant stimuli. Our prediction was that the LPP should be increased for death-related relative to death-unrelated, but equally unpleasant stimulus words. In Experiment 1, this prediction was confirmed. This finding was replicated in Experiment 2, which used a target word detection task. In Experiment 2, both death-related and pleasant words elicited an enhanced LPP, presumably because during the less demanding task, people might have distracted themselves from the mortality reminders by focusing on pleasant words. To summarize, we were able to identify a plausible neurophysiological marker of proximal defenses in the form of an increased LPP to death-related words. PMID:22267519

    The objective of this study was to determine whether maternal residential proximity to a nuclear reactor is associated with prevalence of certain birth defects. The New York State Vital Statistics and Congenital Malformations Registry data (1992-2001) were analyzed for five Hudson Valley counties in a 20-mile radius from the Indian Point nuclear reactor (Buchanan, NY, USA). Four zones of 5-mile increments were used to categorize proximity to the reactor. Data included congenital anomalies, low birth weight, and prematurity. Over the 10-year period, 702 malformations in 666 children were identified from a birth population of 328,124, yielding a regional rate of 2.1 major malformations per 1000 births. The prevalence of defects, low birth weight, and prematurity were not related to proximity to the nuclear power plant. These data did not substantiate an association between maternal proximity to the reactor and certain birth defects and provide baseline data for comparison in the event of a nuclear accident.

    Fractures of the proximal femur are the most devastating outcome of osteoporosis. It is generally understood that age-related changes in hip structure confer increased risk, but there have been few explicit comparisons of such changes in healthy subjects to those with hip fracture. In this study, we used quantitative computed tomography and tensor-based morphometry (TBM) to identify three-dimensional internal structural patterns of the proximal femur associated with age and with incident hip fracture. A population-based cohort of 349 women representing a broad age range (21–97 years) were included in this study, along with a cohort of 222 older women (mean age 79±7 years) with (n=74) and without (n=148) incident hip fracture. Images were spatially normalized to a standardized space, and age- and fracture-specific morphometric features were identified based on statistical maps of shape features described as local changes of bone volume. Morphometric features were visualized as maps of local contractions and expansions, and significance was displayed as Student’s t-test statistical maps. Significant age-related changes included local expansions of regions low in volumetric bone mineral density (vBMD) and local contractions of regions high in vBMD. Some significant fracture-related features resembled an accentuated aging process, including local expansion of the superior aspect of the trabecular bone compartment in the femoral neck, with contraction of the adjoining cortical bone. However, other features were observed only in the comparison of hip fracture subjects with age-matched controls including focal contractions of the cortical bone at the superior aspect of the femoral neck, the lateral cortical bone just inferior to the greater trochanter, and the anterior intertrochanteric region. Results of this study support the idea that the spatial distribution of morphometric features is relevant to age-related changes in bone and independently to fracture risk. In

This study aims to examine the spatial distribution of suicide at a Local Governmental Area (LGA level and identify the LGAs with a high relative risk of suicide in Queensland, Australia, using geographical information system (GIS techniques. Methods Data on suicide and demographic variables in each LGA between 1999 and 2003 were acquired from the Australian Bureau of Statistics. An age standardised mortality (ASM rate for suicide was calculated at the LGA level. GIS techniques were used to examine the geographical difference of suicide across different areas. Results Far north and north-eastern Queensland (i.e., Cook and Mornington Shires had the highest suicide incidence in both genders, while the south-western areas (i.e., Barcoo and Bauhinia Shires had the lowest incidence in both genders. In different age groups (≤24 years, 25 to 44 years, 45 to 64 years, and ≥65 years, ASM rates of suicide varied with gender at the LGA level. Mornington and six other LGAs with low socioeconomic status in the upper Southeast had significant spatial clusters of high suicide risk. Conclusions There was a notable difference in ASM rates of suicide at the LGA level in Queensland. Some LGAs had significant spatial clusters of high suicide risk. The determinants of the geographical difference of suicide should be addressed in future research.

    This detailed view of the Great Barrier Reef, Queensland, Australia (19.5S, 149.5E) shows several small patch reefs within the overall reef system. The Great Barrier Reef, largest in the world, comprises thousands of individual reefs of great variety and are closely monitored by marine ecologists. These reefs are about 6000 years old and sit on top of much older reefs. The most rapid coral growth occurs on the landward side of the reefs.

  2. Proximal and distal styles of pegmatite-related metasomatic emerald mineralization at Ianapera, southern Madagascar

    The Ianapera emerald deposit is located in the Neoproterozoic Vohibory Block of southern Madagascar. The local geology consists of intercalated migmatitic gneissic units and calcareous metasedimentary rocks, containing boudinaged metamorphosed mafic/ultramafic lenses, all intruded by pegmatite veins. These units occur near the hinge of the tightly folded Ianapera antiform, within a few kilometers of the Ampanihy shear zone. Emerald mineralization is hosted by metasomatic phlogopite veins, and bodies developed within the mafic/ultramafic rocks. Based on field and textural relationships, we distinguish proximal and distal styles of mineralization. Proximal mineralization occurs at the contact of pegmatite veins with mafic/ultramafic units; in the distal style, pegmatites are not observed. Three types of emeralds could be distinguished, mainly on the basis of color and mineral zoning. Some of these emeralds have the most Al-depleted and Cr-rich composition ever recorded. Another characteristic feature to the Ianapera deposit and, to our knowledge, yet unreported, is the association of some emeralds with scapolite in metasomatised mafic rocks. Mineral inclusions are common in most emeralds and include phlogopite, carbonates, barite, K-feldspar, quartz, pyrite, zircon, monazite, bastnaesite, phenakite, plus Fe and Cr oxides. However, feldspar and rare earth element-bearing minerals occur predominantly in proximal emeralds, which also have a more incompatible trace-element signature than distal emeralds. We propose a model related to syn- to post-tectonic magmatic-hydrothermal activity. Pegmatitic bodies intruded units of the Ianapera antiform probably during tectonic relaxation. Exsolution of fluids rich in halogens and incompatible elements from the cooling pegmatites caused hydrothermal metasomatism of Cr-bearing mafic/ultramafic rocks in direct contact with the pegmatites. Local fracturing favored fluid infiltration, permitting the formation of distal mineralization

    This paper details contemporary ethical dilemmas encountered by Queensland dentists. An age-stratified sample of 499 dentists resident in Queensland was surveyed. The questionnaire contained scenarios of five common ethical dilemmas. In addition, open-ended questions sought the respondent's most frequent, difficult and recent ethical dilemmas, and where they would seek guidance in dealing with ethical problems. Respondents acknowledged the patient's rights in treatment decisions and the dentist's right to refuse demands for inappropriate treatment. However, responses varied in the extent to which dentists may influence treatment decisions. Few respondents would ignore evidence of poor dental treatment but they are evenly divided in choosing to inform the patient, the dentist or both. Poor quality treatment is the most frequent and difficult dilemma, and half have experienced this problem recently. Requests by patients for fraudulent receipts occur in a third of responses. Dentists develop ethical values from multiple sources but for help with dental ethical problems, 90 per cent of respondents would consult another dentist. Of the ethical dilemmas discussed in this survey, those relating to poor quality treatment confronted most respondents. Also the actions of dentists in dealing with these dilemmas were most varied.

    Around the world, a substantial proportion of motor vehicle crash deaths are recognized as "hidden" suicides. This project sought to progress understandings of drivers who used a motor vehicle to die by suicide in Queensland, Australia, during the period 1990 to 2007. Data for this study were derived from the Queensland Suicide Register and forensic crash investigation case records. Analysis focused on life circumstances and events preceding the death, physical and mental illnesses, past suicidality, and indication of suicide intent (e.g., suicide notes or statements). Compared to cases using other methods, confirmed driver suicides were more likely to be males aged between 25 and 44 years who were employed at the time of death. A large proportion of driver suicides had consumed alcohol immediately prior to the crash and experienced a number of life events, including relationship conflict, legal or criminal issues, and financial problems. These exploratory results indicate the need to educate crash investigators about the characteristics of those who use a motor vehicle to die. Improving the information available on the mental and physical health and background life-related factors of crash victims can help coroners and researchers determine whether these deaths were intentional. Further investigation is needed in order to formulate intervention strategies for those who may be vulnerable to driver suicide.

    Full Text Available Geater Montreal is the third largest city in North America for the garment industry in terms of labour force, after Los Angeles and New York. The industry has however changed partly into a service industry, centered on fashion design, with a focus on international competitiveness but also the role of fashion in Montreal's economic and territorial development. Our article analyzes careers in the fashion design sector, sheds light on the evolution of creative sectors, and shows how these sectors could be better supported to favor local development, as neighborhoods and space design appear important in these creative sectors. We situate our analysis in the theoretical context of career theories, and analyze key moments in careers and the role of intermediate organizations and government programs in supporting these careers. Our paper makes a contribution to our knowledge of career paths in the fashion industry, but also to the role of relational proximity in supporting these careers, and thus local development. It highlights the importance of personal connections, the milieu in which the individual works and functions, the creativity of the individual, as well as the role of the local support organizations and professional associations, including agencies of the provincial government.

    Internationally, best practice for prison health care recommends transferring health service provision from corrections to health authorities. Although it is expected that this change will result in improved health care, there is little evidence of evaluation. This article used qualitative interviews with health service providers to gain insight into the health needs of women's prisons in Queensland, Australia, both prior to and after the transition in health care service provision. We found that service providers identified that problems persisted regardless of service provider and that improvement required increased resources and more fundamental structural changes within prison environments.

    To describe public opinion relating to the fluoridation of drinking water in a sample of the Queensland population. Data were collected by means of a computer-assisted telephone interview survey from a sample of the Queensland population. Descriptive statistics and logistical regression were used to examine associations between variables. Seventy per cent of the total sample supported water fluoridation of their local supply. More than 71% of the total sample agreed that water fluoridation was safe. People living in areas of higher socio-economic/relative socio-economic advantage were more likely to support the addition of fluoride to local drinking water and agree that it was safe. Opinions about fluoridation varied by respondent age and gender. General support was found in this sample of the Queensland population for fluoridation of drinking water. In Queensland, fluoridation of the water supply is now a political decision. Information about public opinion on fluoridation may assist decision makers in the final determination.

    Full Text Available A multiset is a collection of objects in which repetition of elements is essential. This paper is an attempt to explore the theoretical aspects of multiset by extending the notions of compact, proximity relation and proximal neighborhood to the multiset context. Examples of new multiset topologies, open multiset cover, compact multiset and many identities involving the concept of multiset have been introduced. Further, an integral examples of multiset proximity relations are obtained. A multiset topology induced by a multiset proximity relation on a multiset M has been presented. Also the concept of multiset δ- neighborhood in the multiset proximity space which furnishes an alternative approach to the study of multiset proximity spaces has been mentioned. Finally, some results on this new approach have been obtained and one of the most important results is: every T4- multiset space is semi-compatible with multiset proximity relation δ on M (Theorem 5.10.

    To identify the level of public support for a Human Rights Act for Queensland (HRAQ) and for inclusion of the right to health by participants in a public inquiry process. We reviewed the 492 written submissions to the Legal Affairs and Community Safety Committee's Inquiry into a potential HRAQ and the transcripts documenting the public hearings held by the Committee in 2016. A total of 465 written submissions were analysed; 419 (90%) were for a HRAQ. More than 80% of the 'for' submissions advocated the right to health's inclusion. At the seven public hearings, 72 persons made verbal submissions and most supported a HRAQ. Five major themes were identified in our synthesis of the public hearing transcripts. Three related specifically to health and human rights: 1) the need to consider the holistic health and human rights of Indigenous Queenslanders and Indigenous Queensland communities; 2) instilling a human rights culture in Queensland; and 3) access to health care and the underlying determinants of health. The other two themes related to the conduct of the Inquiry: 4) the importance of community participation in developing a HRAQ; and 5) concerns about the public consultation processes. This study found strong support in the majority of submissions for the Queensland Parliament to draft and enact a HRAQ, and for the inclusion of the right to health in such legislation. Implications for public health: The Queensland Parliament's enactment of a HRAQ that expressly included the right to health would increase the accountability and transparency of government health (and related) decision making and resource allocation, and would better identify and address health inequities across the state. This Act is imperative for improving the health and wellbeing of all Queenslanders, particularly rural and remote and Aboriginal and Torres Strait Islander Queenslanders. © 2017 The Authors.

    Full Text Available Abstract Background Evidence about a possible causal relationship between non-specific physical symptoms (NSPS and exposure to electromagnetic fields (EMF emitted by sources such as mobile phone base stations (BS and powerlines is insufficient. So far little epidemiological research has been published on the contribution of psychological components to the occurrence of EMF-related NSPS. The prior objective of the current study is to explore the relative importance of actual and perceived proximity to base stations and psychological components as determinants of NSPS, adjusting for demographic, residency and area characteristics. Methods Analysis was performed on data obtained in a cross-sectional study on environment and health in 2006 in the Netherlands. In the current study, 3611 adult respondents (response rate: 37% in twenty-two Dutch residential areas completed a questionnaire. Self-reported instruments included a symptom checklist and assessment of environmental and psychological characteristics. The computation of the distance between household addresses and location of base stations and powerlines was based on geo-coding. Multilevel regression models were used to test the hypotheses regarding the determinants related to the occurrence of NSPS. Results After adjustment for demographic and residential characteristics, analyses yielded a number of statistically significant associations: Increased report of NSPS was predominantly predicted by higher levels of self-reported environmental sensitivity; perceived proximity to base stations and powerlines, lower perceived control and increased avoidance (coping behavior were also associated with NSPS. A trend towards a moderator effect of perceived environmental sensitivity on the relation between perceived proximity to BS and NSPS was verified (p = 0.055. There was no significant association between symptom occurrence and actual distance to BS or powerlines. Conclusions Perceived proximity to BS

  14. Adaptive relative pose control for autonomous spacecraft rendezvous and proximity operations with thrust misalignment and model uncertainties

    Sun, Liang; Zheng, Zewei

    2017-04-01

    An adaptive relative pose control strategy is proposed for a pursue spacecraft in proximity operations on a tumbling target. Relative position vector between two spacecraft is required to direct towards the docking port of the target while the attitude of them must be synchronized. With considering the thrust misalignment of pursuer, an integrated controller for relative translational and relative rotational dynamics is developed by using norm-wise adaptive estimations. Parametric uncertainties, unknown coupled dynamics, and bounded external disturbances are compensated online by adaptive update laws. It is proved via Lyapunov stability theory that the tracking errors of relative pose converge to zero asymptotically. Numerical simulations including six degrees-of-freedom rigid body dynamics are performed to demonstrate the effectiveness of the proposed controller.

    Proximal femoral osteotomy has been used in cerebral palsy, Perthes disease, hip dysplasia, idiopathic femoral anteversion, and various hip diseases in children and adolescents. Conventionally, a blade plate (BP) has been used. However, the pediatric locking compression plate (LCP) has recently been applied widely. We compared the hardware-related complications of the BP and the LCP as well as the factors influencing these complications in patients who have undergone a proximal femoral osteotomy in children and adolescents. We enrolled consecutive patients aged less than or equal to 20 years who had undergone proximal femoral osteotomy with BP or LCP between May 2003 and December 2014, and who were followed up until 6 months after hardware removal. Following consensus building, hardware-related complications were identified from the patients' medical records and hip radiographs. Patient age, sex, type of plate, and Gross Motor Function Classification System (GMFCS) level in cerebral palsy patients were evaluated as possible risk factors, and a generalized estimating equation was used to assess the risk factors for hardware-related complications. A total of 417 hips from 251 patients were finally included in this study. Seven losses of fixation around the plate (five patients, 3.0%) occurred in the BP, three implant-related fractures (three patients, 3.6%) occurred in the LCP, and there was no significant difference (P=0.74). All hardware-related complications occurred in cerebral palsy patients, and the implant-related fractures occurred in patients with GMFCS IV/V. The risk of complications increased with age (P=0.002). The risk of loss of fixation around the BP is a well-known complication. However, LCP is not without hardware-related complications. The LCP provides strong stability of fixation. However, it is speculated that the LCP is related to implant-related fractures because of the stress shielding effect. Therefore, care should be exercised when using a

    We investigated the shape integrity of silver nanoparticle ink patterns formed by reverse offset printing, focusing particularly on the proximity effect of neighbouring patterns due to the local deformation of a polydimethylsiloxane (PDMS) blanket during contact with a hard cliché. We performed printing tests using a cliché having circular patterns with smaller neighbouring circles located at various distances (2-20 µm), and the results revealed that as we decrease the thickness of PDMS and the inter-pattern gap distance, and as we increase the printing indentations, the shape integrity of the printed pattern was worsened. A complementary numerical simulation of PDMS deformations suggested that the pattern distortion during the contact with clichés was caused by the horizontal deformation of PDMS during the printing, which becomes a significant burden when the uplifted region of PDMS is closer to the gap distance of each pattern. Our analysis further indicates that during printing, there is slipping of the ink at the PDMS interface. In addition, we examined the effects of a synchronization mismatch in a roll-to-sheet printing on the pattern size tolerance. The magnitude of the size distortions was severely influenced not only by the mismatch ratio but also by the nip width. This result verifies the scraping of the ink accompanied by the slipping of the PDMS during the printing process, and thereby determines the size tolerance of printed patterns in reverse offset printing. Finally, we discuss the optimization of process parameters to ensure the size integrity of reverse offset printing.

    Despite the wide application of open reduction and internal fixation with locking plates for the treatment of proximal humeral fractures, the surgical invasive approach remains controversial. This study aimed to evaluate the pros and cons of the minimally invasive lateral approach for the treatment of proximal humeral fracture (PHF) in comparison with the deltopectoral approach. All patients who sustained a PHF and received open reduction and internal fixation (ORIF) surgery with locking plate through either minimally invasive subacromial approach or conventional deltopectoral approach between January 2008 and February 2012 were retrospectively analyzed. Patients were divided into the conventional group and min-group according to the surgical incision. Surgery-related information, postoperative radiography, complications, and shoulder functional measurement scores in a 2-year follow-up were collected and evaluated. Ninety-one patients meeting the inclusion criteria were included in this study. We observed a significant difference in both surgery time (81.8±18.3 vs. 91.0±18.4) (p=0.021) and blood loss (172±54.2 vs. 205±73.6) (p=0.016) between the min-group and conventional group. Compared to the conventional group, the min-group had significantly better Constant-Murley score and DASH score at early follow-up (pfractures, was observed in the min-group, the conventional group obtained better movement in the 4-part fractures. The minimally invasive lateral approach is the optimal alternative for the treatment of Neer's type 2 and 3 proximal humerus fractures.

    Implant design may affect risk of fracture, especially in the proximal femur, which has been shown to have the highest risk of implant-related fracture (IRF). Blade plate (BPL) and screw-side plate (SSP) implants are used to stabilize proximal femoral osteotomies (PFOs). Our goal was to compare BPL and SSP constructs with regard to the rate, location, and timing of IRF in children undergoing PFOs. We retrospectively reviewed clinical and radiographic records from 1 pediatric orthopaedic practice from 1995 through 2010. We identified 734 children 18 years or younger who underwent PFO with a BPL (480 patients) or an SSP (254 patients). Manufacture and style of implants were consistent throughout this period. There were no significant differences between the 2 groups in terms of mean age, sex, race, or diagnosis. The 2 groups were compared with respect to the rate, location, and timing of IRF. The t, Z, χ, and Fisher exact tests were used to analyze the data (statistical significance, Ptimes to fracture were 3.8±2.9 and 2.4±2.3 years (P=0.39) in the BPL and SSP groups, respectively. The risk of IRF in children after PFO is substantial. Despite differences in design, there was no significant difference between BPL and SSP implants with respect to IRF risk. Level III.

  20. Assessing the effect of the Queensland "Summer of Disasters" on perceptions of collective efficacy.

    The collective efficacy literature suggests that neighborhoods with higher collective efficacy have fewer problems of disorder, increased volunteerism, and higher levels of life satisfaction and wellbeing, along with the increased potential for resilience in the face of a disaster. Although perceptions of collective efficacy typically remain stable over time, rapid or sudden social change, such as experiencing a natural disaster, has the potential to disrupt the neighborhood and the individuals within - including their perceptions of the regulatory mechanisms of collective efficacy. Still, the effect of a major disaster on perceptions of collective efficacy remains relatively unexamined. Longitudinal survey data collected before and after the Queensland flood and cyclone disasters permit a unique investigation of the impact of the disaster on perceptions of social control and social cohesion before and after the disaster. Results show that after this major natural disaster, respondents who were proximately affected reported decreased levels of collective efficacy. Also, persons who experienced the biggest decrease in perceived collective efficacy were those that had lower levels of collective efficacy prior to the disaster. We discuss the mechanisms surrounding disaster preparedness, response, and recovery that may contribute to changing perceptions of collective efficacy. Copyright © 2015 Elsevier Inc.

    Waste generated from construction and building demolition work constitutes about 68% of all solid waste generated each year in South East Queensland. Consequently, it has created a serious waste management problem. The State Governments of Victoria and New South Wales have been encouraging the use of recycled materials from construction and related waste; they have also promulgated specifications for their use. In Queensland, however, similar regulations are not anticipated in the near future, which explains the lack of funded research conducted in this important arena. This paper presents an evaluation of the prevailing waste recycling practices in Queensland. Nine sites were visited, including two construction sites, three demolition sites, three recycling plants and one landfill in South East Queensland. The difficulties encountered by the recycling programme operators and their associates at these sites are described and the benefits of recycling construction materials are presented. One of the major barriers is that the local councils disallow the use of recycled materials in new construction work. To help rectify these impediments to recycling, recommendations are given to increase the use of recycled construction waste in South East Queensland.

    Hypospadias results from abnormal development of the penis that leaves the urethral meatus proximal to its normal glanular position. Meatal position may be located anywhere along the penile shaft, but more severe forms of hypospadias may have a urethral meatus located at the scrotum or perineum. The spectrum of abnormalities may also include ventral curvature of the penis, a dorsally redundant prepuce, and atrophic corpus spongiosum. Due to the severity of these abnormalities, proximal hypospadias often requires more extensive reconstruction in order to achieve an anatomically and functionally successful result. We review the spectrum of proximal hypospadias etiology, presentation, correction, and possible associated complications. PMID:21516286

    Full Text Available Abstract Background It remains unclear whether it is possible to develop a spatiotemporal epidemic prediction model for cryptosporidiosis disease. This paper examined the impact of social economic and weather factors on cryptosporidiosis and explored the possibility of developing such a model using social economic and weather data in Queensland, Australia. Methods Data on weather variables, notified cryptosporidiosis cases and social economic factors in Queensland were supplied by the Australian Bureau of Meteorology, Queensland Department of Health, and Australian Bureau of Statistics, respectively. Three-stage spatiotemporal classification and regression tree (CART models were developed to examine the association between social economic and weather factors and monthly incidence of cryptosporidiosis in Queensland, Australia. The spatiotemporal CART model was used for predicting the outbreak of cryptosporidiosis in Queensland, Australia. Results The results of the classification tree model (with incidence rates defined as binary presence/absence showed that there was an 87% chance of an occurrence of cryptosporidiosis in a local government area (LGA if the socio-economic index for the area (SEIFA exceeded 1021, while the results of regression tree model (based on non-zero incidence rates show when SEIFA was between 892 and 945, and temperature exceeded 32°C, the relative risk (RR of cryptosporidiosis was 3.9 (mean morbidity: 390.6/100,000, standard deviation (SD: 310.5, compared to monthly average incidence of cryptosporidiosis. When SEIFA was less than 892 the RR of cryptosporidiosis was 4.3 (mean morbidity: 426.8/100,000, SD: 319.2. A prediction map for the cryptosporidiosis outbreak was made according to the outputs of spatiotemporal CART models. Conclusions The results of this study suggest that spatiotemporal CART models based on social economic and weather variables can be used for predicting the outbreak of cryptosporidiosis in

    2006-05-01

    This study examined the relationships among distal (paternal and maternal family history of alcohol problems and violence) and proximal (general alcohol use, acute use associated with conflict incidents, alcohol-aggression expectancies) factors and physical aggression severity among 125 men and 125 women recruited from substance abuse treatment. Paternal alcohol problem history (PA) was related to alcohol-aggression expectancies, but no family history factors were related to general or acute alcohol use. Separate analyses examining predictors of aggression were conducted, one with general alcohol use and one with acute alcohol use. In both analyses, alcohol use and the maternal violence (MV) by PA interaction were significant. Specifically, MV was associated with aggression severity for those with a history of PA. The general alcohol use model also revealed significant alcohol by expectancy and MV by gender interactions. The findings suggest that expectancies are not the primary mediator of the alcohol-aggression relationship, alcohol use measurement issues may impact whether expectancies are observed to moderate the alcohol-aggression relationship, and that both maternal and paternal family history factors appear to impact aggression severity.

    This study investigated sixty-six 5-needle pine growth chronologies from 1896 to their end years in order to identify potential patterns related to linear trends in ring width. Individual chronology responses to climate were also evaluated by comparing the chronologies with seasonal temperature and precipitation data from 1896 to the present date. Chronologies exhibiting similar patterns of climate response were grouped in order to examine the role of treeline proximity on climate-growth relationships. Ring width measurements for pine sites located in the western United States were obtained from the International Tree Ring Data Bank. Growth indices were compared among all sites in order to assess the relative strength of common signals with increasing distance. Pearson correlations were used to calculate linear trends for each chronology. A cluster analysis of climate response patterns indicated that most chronologies positively associated with temperatures were located near upper treeline and contained significant positive linear trends. The study suggested that 5-needle pine treeline chronologies may be used as predictors in temperature reconstructions. However, care must be taken to determine that collection sites have not been impacted by disturbances such as fire or insect outbreaks. 35 refs., 2 tabs., 5 figs.

    2016-01-01

    Proximal Hamstring Tendinopathy-related Sciatic Nerve Entrapment (PHTrSNE) is a neuropathy caused by fibrosis interposed between the semimembranosus tendon and the sciatic nerve, at the level of the ischial tuberosity. Ultrasound-guided Intratissue Percutaneous Electrolysis (US-guided EPI) involves galvanic current transfer within the treatment target tissue (fibrosis) via a needle 0.30 to 0.33 mm in diameter. The galvanic current in a saline solution instantly develops the chemical process of electrolysis, which in turn induces electrochemical ablation of fibrosis. In this article, the interventional procedure is presented in detail, and both the strengths and limits of the technique are discussed. US-guided EPI eliminates the fibrotic accumulation that causes PHTrSNE, without the semimembranosus tendon or the sciatic nerve being directly involved during the procedure. The technique is however of limited use in cases of compression neuropathy. US-guided EPI is a technique that is quick to perform, minimally invasive and does not force the patient to suspend their activities (work or sports) to make the treatment effective. This, coupled to the fact that the technique is generally well-tolerated by patients, supports use of US-guided EPI in the treatment of PHTrSNE.

    The aim of this study was to evaluate the effect of the amount of setback movement and intraoperative clockwise rotation of the proximal segments on postoperative stability after orthognathic surgery to correct mandibular prognathism. Thirty-six patients with mandibular prognathism who underwent orthognathic surgery with bilateral sagittal split ramus osteotomy were evaluated. The amount of postoperative relapse was analyzed using a cephalometric analysis. Six months after surgery, the mean backward movement of the mandible at point B was 11.2 mm, the mean intraoperative clockwise rotation of the proximal segment was 4.3° and the amount of postoperative relapse at point B was 2.3 mm (20.3%) on average. The tendency of relapse did not significantly increase with the amount of setback but did increase significantly with the intraoperative clockwise rotation of the proximal segment. This study suggested that postoperative relapse after mandibular setback surgery might be more related to the degree of the intraoperative clockwise movement of the proximal segment, rather than the amount of setback movement. When the amount of mandibular setback is considerable, postoperative relapse might be minimized with adequate control of the intraoperative positioning of the proximal segments.

    Full Text Available Background. There have been few reports of nucleotide analogue-related renal tubular dysfunction (RTD in CHB patients. We assessed the prevalence and presentation of nucleotide analogue-related proximal RTD. Methods. A cross-sectional study was performed in CHB patients taking nucleotide analogues. Inclusion criteria were patients who were on adefovir or tenofovir as mono- or add-on therapy with lamivudine (LAM >1 year. Serum and urine were collected. Fractional excretion of phosphate (FEPO4, uric acid (FEUA, and potassium was calculated. Renal losses were defined based on the criteria: protein (24-hour urine protein >150 mg, glucose (glycosuria with normoglycemia, phosphate (FEPO4 >18%, uric acid (FEUA >15%, potassium (renal potassium losses with hypokalemia, and bicarbonate (normal gap acidosis. Subclinical and overt proximal RTD were defined when 2 and ≥3 criteria presented. Results. Ninety-two patients were enrolled. The mean duration of nucleotide analogue taking was 55.1±29.6 months. Proximal RTD was found in 24 (26.1% patients (subclinical 15 (16.3% and overt 9 (9.8%. The severity of RTD was associated with the duration of nucleotide analogue (P=0.01. Conclusions. The prevalence of proximal RTD in CHB patients taking nucleotide analogues was 26%. The severity of RTD was associated with the treatment duration. Comprehensive testing is necessary for early detecting nucleotide analogue-related nephrotoxicity.

    The coronal subluxation of the proximal tibia relative to the distal femur is a common radiological finding in patients with knee osteoarthritis. The purpose was to evaluate whether the coronal subluxation was corrected after opening wedge high tibial osteotomy (OWHTO), and whether this subluxation was one cause of inconsistency between the actual and predicted alignments (correction loss). Fifty-one patients (55 knees) were treated with OWHTO. The change of location between the intersection points of the femoral and tibial axes on the tibial plateau (subluxation-C), the change of location between the lines through the most lateral points of the lateral femoral and tibial condyles (subluxation-L), and joint space angle (JSA) were compared in standing knee radiographs before and one year after OWHTO. The subluxation-C and subluxation-L were converted to a percentage of the tibial plateau width. The mean subluxation-C of 6.5% before OWHTO significantly increased to a mean subluxation-C of 7.3% one year after OWHTO. The mean subluxation-L of 6.3% and JSA of 4.5° before OWHTO significantly decreased to a subluxation-L of 1.8% and JSA of 3.3° one year after OWHTO. The change in subluxation-L correlated with the change in femorotibial angle and correction loss (r=0.634, Pfemur after OWHTO. This medial shift correlated with the correction loss. The coronal subluxation might be one cause of correction loss. Copyright © 2016 Elsevier B.V. All rights reserved.

    2010-05-01

    The seasonal weather of southeastern Queensland (SEQ) is commonly described by a wet and a dry season. Rainfall in this area has been declining for the past fifty years and climate projections indicate decreasing trends in annual rainfall and increases in temperature. These factors combined with population growth suggest a need for Queensland to re-evaluate its water management. In order to understand the rainfall variability of SEQ, it is useful to consider the impact of the different weather patterns or synoptic regimes on the regional rainfall. Previous studies have examined the synoptic patterns associated with extreme wind and rainfall events in SEQ and the correlation between rainfall in northern Queensland and atmospheric variables, but a comprehensive climatology for the SEQ region is missing. Analysis of routine soundings is found to reveal relationships between surface precipitation and atmospheric structure. Cluster analysis was performed on daily radiosonde data for Brisbane Airport spanning the period 01/01/1990-11/11/2009. The clustering was initially performed on seven atmospheric variables: total-totals, 850mb winds, wind shear between 850mb and 500mb, moisture flux and total water calculated from the sounding data. A sensitivity study reveals that the moisture flux parameters followed by total water and total-totals are the key variables in determining the regimes. The clusters were combined with daily rainfall records spanning the period 01/01/1995 - 01/06/2008 to determine the contribution of each regime to monthly rainfall. The seven-cluster case describes three separate southeasterly regimes, three westerly regimes and an easterly regime. The contribution of each regime to annual rainfall was also determined. The regimes for SEQ can be divided into ‘wet' and ‘dry' cases. It is apparent that the rainfall is largely limited to the coastal strip, with maxima near regions with steep terrain. The main rainfall period is from November through to

    Full Text Available Abstract Background Drinking coffee has been linked to reduced calcium conservation, but it is less clear whether it leads to sustained bone mineral loss and if individual predisposition for caffeine metabolism might be important in this context. Therefore, the relation between consumption of coffee and bone mineral density (BMD at the proximal femur in men and women was studied, taking into account, for the first time, genotypes for cytochrome P450 1A2 (CYP1A2 associated with metabolism of caffeine. Methods Dietary intakes of 359 men and 358 women (aged 72 years, participants of the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS, were assessed by a 7-day food diary. Two years later, BMD for total proximal femur, femoral neck and trochanteric regions of the proximal femur were measured by Dual-energy X-ray absorptiometry (DXA. Genotypes of CYP1A2 were determined. Adjusted means of BMD for each category of coffee consumption were calculated. Results Men consuming 4 cups of coffee or more per day had 4% lower BMD at the proximal femur (p = 0.04 compared with low or non-consumers of coffee. This difference was not observed in women. In high consumers of coffee, those with rapid metabolism of caffeine (C/C genotype had lower BMD at the femoral neck (p = 0.01 and at the trochanter (p = 0.03 than slow metabolizers (T/T and C/T genotypes. Calcium intake did not modify the relation between coffee and BMD. Conclusion High consumption of coffee seems to contribute to a reduction in BMD of the proximal femur in elderly men, but not in women. BMD was lower in high consumers of coffee with rapid metabolism of caffeine, suggesting that rapid metabolizers of caffeine may constitute a risk group for bone loss induced by coffee.

    Australia has seen a significant increase in people aged over 65 years accessing general practice services over the last decade. Although people aged 65 years and over comprise 14% of the total population, this age demographic accounts for the largest proportion of general practitioner (GP)-patient encounters. Access to general practice is important for older Australians as the burden of chronic disease increases with age. A geographic information system, ArcGIS, was used to assess geographic access to general practice for older people residing in the regional Queensland towns of Mackay, Townsville and Cairns. Geographic units with high proportions of over 65-year-old people were spatially analysed in relation to proximity to geomapped general practices with a 2-km buffer zone. Modelling of changes in access was performed with the strategic location of a new general practice where gaps existed. Geographic access to general practice for the older population was poorest in Cairns despite a high population density. Addition of a single, strategically placed general practice in Cairns markedly improved access. Socioeconomic analysis suggested that general practices were appropriately located in areas of greatest need. Geographic information systems provide a means to map population characteristics against service locations to assist in strategic development and location of future health services.

    Identification of adult fruit flies primarily involves microscopic examination of diagnostic morphological characters, while immature stages, such as larvae, can be more problematic. One of the Australia's most serious horticultural pests, the Queensland Fruit Fly (Bactrocera tryoni: Tephritidae), is of particular biosecurity/quarantine concern as the immature life stages occur within food produce and can be difficult to identify using morphological characteristics. DNA barcoding of the mitochondrial Cytochrome Oxidase I (COI) gene could be employed to increase the accuracy of fruit fly species identifications. In our study, we tested the utility of standard DNA barcoding techniques and found them to be problematic for Queensland Fruit Flies, which (i) possess a nuclear copy (a numt pseudogene) of the barcoding region of COI that can be co-amplified; and (ii) as in previous COI phylogenetic analyses closely related B. tryoni complex species appear polyphyletic. We found that the presence of a large deletion in the numt copy of COI allowed an alternative primer to be designed to only amplify the mitochondrial COI locus in tephritid fruit flies. Comparisons of alternative commonly utilized mitochondrial genes, Cytochrome Oxidase II and Cytochrome b, revealed a similar level of variation to COI; however, COI is the most informative for DNA barcoding, given the large number of sequences from other tephritid fruit fly species available for comparison. Adopting DNA barcoding for the identification of problematic fly specimens provides a powerful tool to distinguish serious quarantine fruit fly pests (Tephritidae) from endemic fly species of lesser concern. © 2012 Blackwell Publishing Ltd.

    2017-01-01

    Simple Summary An up-to-date and comprehensive understanding of the characteristics and outcomes of dogs entering shelters is required for implementing targeted strategies to reduce euthanasia of healthy and treatable dogs in Australia. Currently, there are few up-to-date Australian data published on dogs entering shelters, and their outcomes. Of dogs entering the Royal Society for Prevention of Cruelty to Animals, Queensland shelters in 2014, the majority (58%) were strays and 26% were puppies. Only 18% of dogs >6 months were desexed. Most dogs were reclaimed (32%) or adopted (43%). Strategies targeted to locations and breeds overrepresented by admissions are required to reduce shelter admissions, particularly of strays and unwanted litters. Abstract Over 200,000 stray and surrendered dogs are admitted to shelters and municipal facilities in Australia each year, and approximately 20% are euthanized. Contemporary, comprehensive data on the characteristics and outcomes of dogs entering shelters are required to reduce shelter admissions and euthanasia. However, there are currently limited up-to-date data published on dog admission into shelters. A retrospective single cohort study was conducted to describe the characteristics and outcomes of the dog population entering Royal Society for Prevention of Cruelty to Animals, Queensland (RSPCA-QLD) shelters in 2014 (n = 11,967). The majority of dog admissions were strays from the public (24%) or from municipal councils (34%). Just over a quarter of admissions were puppies, 18% of adults (>6 months) were desexed, and the majority of admissions were crossbred dogs (92%). The majority of owner surrenders (86%) were due to human-related reasons. Most dogs were reclaimed (32%) or adopted (43%) and aggression was the most common reason for euthanasia of adult dogs (45%). Low-cost or free desexing and identification programs targeted to areas and breeds contributing to high intake, and increased support services for owners at

    A computed tomography (CT) study. To evaluate the changed relative positions of esophagus in proximal thoracic (PT) curves of adolescent idiopathic scoliosis (AIS) patients and analyze the potential risks of esophageal injuries from thoracic pedicle screw (TPS) insertion. Translation and rotation of the vertebrae could lead to altered relative positions of surrounding vital structures in AIS patients. The changed positions of aorta and spinal cord in main thoracic (MT) curve have been comprehensively investigated; however, no studies have analyzed the relative position of esophagus in PT curve. Twenty patients with complete proximal thoracic (CPT group) curve, 22 patients with fractional proximal thoracic (FPT group) curve, and 14 normal patients with a straight spine (normal group) were included. Axial CT images from T2 to T5 at the midvertebral body level were obtained to evaluate esophagus-vertebral angle (EVA, defined as 0° when the esophagus was located directly lateral to the left, 90° when strictly anterior, and 180° when directly lateral to the right). The percentages of esophagus in the direction of screw passage were calculated to analyze potential risks of esophageal injuries during TPS insertion. EVA in the FPT group was significantly smaller than that in the normal group (P spine and result in different potential risks of esophageal injuries during TPS insertion. Spine surgeons should choose appropriate pedicle screw length to avoid anterior cortical perforation in the PT region of AIS patients.

    Full Text Available Rehabilitation of marine turtles in Queensland has multifaceted objectives. It treats individual animals, serves to educate the public, and contributes to conservation. We examined the outcome from rehabilitation, time in rehabilitation, and subsequent recapture and restranding rates of stranded marine turtles between 1996 and 2013 to determine if the benefits associated with this practice are cost-effective as a conservation tool. Of 13,854 marine turtles reported as stranded during this 18-year period, 5,022 of these turtles were stranded alive with the remainder verified as dead or of unknown condition. A total of 2,970 (59% of these live strandings were transported to a rehabilitation facility. Overall, 1,173/2,970 (39% turtles were released over 18 years, 101 of which were recaptured: 77 reported as restrandings (20 dead, 13 alive subsequently died, 11 alive subsequently euthanized, 33 alive and 24 recaptured during normal marine turtle population monitoring or fishing activities. Of the turtles admitted to rehabilitation exhibiting signs of disease, 88% of them died, either unassisted or by euthanasia and 66% of turtles admitted for unknown causes of stranding died either unassisted or by euthanasia. All turtles recorded as having a buoyancy disorder with no other presenting problem or disorder recorded, were released alive. In Queensland, rehabilitation costs approximately $1,000 per animal per year admitted to a center, $2,583 per animal per year released, and $123,750 per animal per year for marine turtles which are presumably successfully returned to the functional population. This practice may not be economically viable in its present configuration, but may be more cost effective as a mobile response unit. Further there is certainly benefit giving individual turtles a chance at survival and educating the public in the perils facing marine turtles.

    Much of southern and eastern Australia including Queensland have experienced rainfall declines over recent decades affecting agricultural production and accelerating water infrastructure development. Rainfall declines from southern Australia have now been directly related to changes in the Southern Annular Mode (SAM) and the subtropical ridge. In southern and coastal Queensland, the rainfall declines have occurred mostly in the austral summer and autumn. Observations from this region reveal the rainfall decline is correlated to an increase in the mean sea level pressure (MSLP) at many stations. The largest increases in MSLP are over southeast Queensland and coastal regions, where some of the largest rainfall declines occur. This study indicates the subtropical ridge as one of the main factors in the rainfall decline over this region. SAM is also likely to be important, although its seasonal influence, apart from winter, is harder to determine.

    A retrospective analysis of hospitalisation due to oral and dental conditions (ODC) was performed for patients in Queensland. The aim was to identify the rate and cost of hospitalisation and to examine the association between hospitalisation and age, geographical location and Indigenous status. There were 81528 admissions to Queensland's hospitals due to ODC during the 3-year study period (2011-2013). The annual cost of ODC-related hospitalisation was estimated to be AU$87million.

    2014-06-01

    Full Text Available The aim of the study was to examine the correlation between the chosen position of screws and the complications observed in patients who underwent locked plating of proximal humeral fractures. We evaluated radiographs of 367 patients treated by locked-plating for proximal humeral fractures. Radiographs were taken at one day, 6 weeks, 3 months and 6 months after surgery, and were analyzed for secondary fracture displacement, loss of fixation, cutting out of screws and necrosis of the humeral head. Secondary loss of fixation occurred in 58 cases (15.8% and among those cutting out of screws was observed in 25 cases (6.8%. In cases of secondary loss of fixation a mean of 6.7 screws were used to fix the fracture (vs 6.6, P=0.425. There was neither significant correlation between position of screws and the occurrence of postoperative loss of fixation in Spearman correlation nor relationship from backward logistic regression analysis. Loss of fixation following locked plating of proximal humeral fractures does not relate to the number of screws and their positions in the humeral head. In consequence, anatomic fracture reduction and restoration of the humeral head-shaft angle are still important factors and should not be disregarded.

  12. The Distribution and Density of Water Mice (Xeromys myoides in the Maroochy River of Southeast Queensland, Australia.

    Directory of Open Access Journals (Sweden)

    Janina Kaluza

    Full Text Available The water mouse is a small and vulnerable rodent present in coastal areas of south-west Papua New Guinea, and eastern Queensland and the Northern Territory of Australia. Current knowledge regarding the distribution of the water mouse is incomplete and the loss of one local population has been documented in southeast Queensland, a region where pressures from urban and industrial development are increasing. Water mouse populations have not been studied intensively enough to enable the primary factors responsible for the local decline to be identified. We surveyed the distribution and density of the water mouse along the Maroochy River of southeast Queensland, near the southern extent of the species' range, to gather baseline data that may prove valuable for detecting any future decline in this population's size or health. All areas of suitable habitat were surveyed on foot or by kayak or boat over a three-year period. We found 180 water mouse nests, of which ~94% were active. Permanent camera monitoring of one nest and limited supplementary live trapping suggested that up to three individual mice occupied active nests. Water mouse density was estimated to be 0.44 per hectare of suitable habitat along the Maroochy River. Should future monitoring reveal an adverse change in the water mouse population on the Maroochy River, a concerted effort should be made to identify contributing factors and address proximate reasons for the decline.

  13. Telepharmacy for remote hospital inpatients in north-west Queensland.

    2017-12-01

    Clinical pharmacy service delivery is currently a significant challenge in remote areas. Mount Isa Base Hospital provides clinical pharmacy support to ten remote sites across an area of over 300,000 square kilometres. These sites do not have on-site pharmacists available and, due to the vast distances and unpredictable travel conditions, the outreach pharmacist from Mount Isa Base Hospital only visits sporadically. Provision of direct patient care and advice on medication safety with this model was restricted and insufficient. Telepharmacy provides an opportunity for these services to be vastly expanded. In an attempt to increase pharmacist accessibility for remote hospital sites, the Mount Isa Base Hospital pharmacy department developed an inpatient telepharmacy service. Telehealth equipment is being used to communicate directly with patients and hospital staff, review inpatient medication charts, generate patient medication lists, identify and resolve clinical interventions and provide medication-related advice and counselling. As a result of this implementation, all patients and health professionals in remote north-west Queensland hospitals now have access to a pharmacist. The number of inpatient medication reviews, clinical interventions and patient-pharmacist/clinician-pharmacist interactions occurring at each remote hospital site has increased. Since service initiation, 106 medication-related reviews have been completed via telepharmacy, including 48 patient interactions, and 111 medication-related interventions have been made. This paper outlines the process for the development of an inpatient telepharmacy service for remote hospitals and discusses the benefits and limitations associated with implementation.

    Full Text Available Koala populations in southeast Queensland are under threat from many factors, particularly habitat loss, dog attack, vehicle trauma and disease. Animals not killed from these impacts are often rescued and taken into care for rehabilitation, and eventual release back to the wild if deemed to be healthy. This study investigated current rescue, rehabilitation and release data for koalas admitted to the four major wildlife hospitals in southeast Queensland (Australia Zoo Wildlife Hospital (AZWH, Currumbin Wildlife Sanctuary Hospital (CWH, Moggill Koala Hospital (MKH and the Royal Society for the Prevention Against Cruelty to Animals Wildlife Hospital at Wacol (RSPCA, and suggests aspects of the practice that may be changed to improve its contribution to the preservation of the species. It concluded that: (a the main threats to koalas across southeast Queensland were related to urbanization (vehicle collisions, domestic animal attacks and the disease chlamydiosis; (b case outcomes varied amongst hospitals, including time spent in care, euthanasia and release rates; and (c the majority (66.5% of rescued koalas were either euthanized or died in care with only 27% released back to the wild. The results from this study have important implications for further research into koala rescue and rehabilitation to gain a better understanding of its effectiveness as a conservation strategy.

    Patients with heart failure (HF) show abnormal arterial stiffening. We examined 60 patients (52.1 +/- 12, 8 years) with non-ischaemic dilated cardiomyopathy (NIDC), New York Heart Association II-III, in sinus rhythm, left ventricular ejection fraction 30.1 +/- 8.6%, and 44 normals. All subjects underwent an echocardiographic study and a cardiopulmonary exercise test. We evaluated the segmental proximal aorta (AO) pulse wave velocity (PWV) in the region of aortic arch with a new echo-method: from the suprasternal view, the distance between ascending and descending AO was measured with two-dimensional ultrasound, and the aortic flow wave transit time (TT) was measured with pulsed-wave Doppler. Pulse wave velocity was calculated as aortic distance/TT. Patients showed increased PWV (7.4 +/- 2.9 vs. 4.8 +/- 1.1 m/s, P age, sex, and body mass) VO(2) (both P exercise capacity. The echocardiographic assessment of the regional aorta PWV seems to be clinically important.

    2014-02-15

    With fatiguing exercise, firing of group III/IV muscle afferents reduces voluntary activation and force of the exercised muscles. These afferents can also act across agonist/antagonist pairs, reducing voluntary activation and force in nonfatigued muscles. We hypothesized that maintained firing of group III/IV muscle afferents after a fatiguing adductor pollicis (AP) contraction would decrease voluntary activation and force of AP and ipsilateral elbow flexors. In two experiments (n = 10) we examined voluntary activation of AP and elbow flexors by measuring changes in superimposed twitches evoked by ulnar nerve stimulation and transcranial magnetic stimulation of the motor cortex, respectively. Inflation of a sphygmomanometer cuff after a 2-min AP maximal voluntary contraction (MVC) blocked circulation of the hand for 2 min and maintained firing of group III/IV muscle afferents. After a 2-min AP MVC, maximal AP voluntary activation was lower with than without ischemia (56.2 ± 17.7% vs. 76.3 ± 14.6%; mean ± SD; P muscle afferents from the hand decreased voluntary drive and force of AP. Moreover, this effect decreased voluntary drive and torque of proximal unfatigued muscles, the elbow flexors. Fatigue-sensitive group III/IV muscle nociceptors act to limit voluntary drive not only to fatigued muscles but also to unfatigued muscles within the same limb.

    Mapping with Landsat images usually is done by selecting single types of features, such as soils, vegetation, or rocks, and creating visually interpreted or digitally classified maps of each feature. Individual maps can then be overlaid on or combined with other maps to characterize the terrain. Integrated terrain mapping combines several terrain features into each map unit which, in many cases, is more directly related to uses of the land and to methods of land management than the single features alone. Terrain brightness, as measured by the multispectral scanners in Landsat 1 and 2, represents an integration of reflectance from the terrain features within the scanner's instantaneous field of view and is therefore more correlatable with integrated terrain units than with differentiated ones, such as rocks, soils, and vegetation. A test of the feasibilty of the technique of mapping integrated terrain units was conducted in a part of southwestern Queensland, Australia, in cooperation with scientists of the Queensland Department of Primary Industries. The primary purpose was to test the use of digital classification techniques to create a 'land systems map' usable for grazing land management. A recently published map of 'land systems' in the area (made by aerial photograph interpretation and ground surveys), which are integrated terrain units composed of vegetation, soil, topography, and geomorphic features, was used as a basis for comparison with digitally classified Landsat multispectral images. The land systems, in turn, each have a specific grazing capacity for cattle (expressed in beasts per km 2 ) which is estimated following analysis of both research results and property carrying capacities. Landsat images, in computer-compatible tape form, were first contrast-stretched to increase their visual interpretability, and digitally classified by the parallelepiped method into distinct spectral classes to determine their correspondence to the land systems classes and

    Proximal palmar/plantar osteochondral fragmentation of the first phalanx is a frequent radiographic finding in Standardbred horses. These lesions are routinely removed prior to the onset of a racing career with no evidence to support the timing of this surgical intervention. To determine whether horses racing before surgery slowed as they approached surgery date and whether they speeded up after surgery. To investigate the factors affecting whether a horse raced after surgery and compare the performance of horses that did and did not race before surgery. A retrospective study using 193 Swedish Standardbred trotters. Medical records and radiographs of each horse were examined. Racing data were retrieved from official online records. Generalising estimating equations were used to examine presurgery racing performance and determine whether this differed between horses that raced before surgery and those that had not. Multivariable regression was used to examine career earnings and number of career races. Horses racing before surgery neither slowed as they approached surgery, nor speeded up after surgery. Race speed of horses raced before surgery was not different from those that only raced after surgery. Racing before surgery was not associated with whether horses raced following surgery. Only horses with 3 affected legs had slower race speeds than other horses. No other horse level variables affected race speed, number of career races, career earnings or top speed. There was no significant difference in race speed between horses that raced before surgery and those that did not. Horses did not slow down prior to surgery. Horses with 3 affected legs ran slower than those with only a single or 2 affected limbs. There was no association between timing of surgery and race speed or career longevity. The potential benefits of surgical intervention should be critically examined. © 2014 EVJ Ltd.

    Over 200,000 stray and surrendered dogs are admitted to shelters and municipal facilities in Australia each year, and approximately 20% are euthanized. Contemporary, comprehensive data on the characteristics and outcomes of dogs entering shelters are required to reduce shelter admissions and euthanasia. However, there are currently limited up-to-date data published on dog admission into shelters. A retrospective single cohort study was conducted to describe the characteristics and outcomes of the dog population entering Royal Society for Prevention of Cruelty to Animals, Queensland (RSPCA-QLD) shelters in 2014 (n = 11,967). The majority of dog admissions were strays from the public (24%) or from municipal councils (34%). Just over a quarter of admissions were puppies, 18% of adults (>6 months) were desexed, and the majority of admissions were crossbred dogs (92%). The majority of owner surrenders (86%) were due to human-related reasons. Most dogs were reclaimed (32%) or adopted (43%) and aggression was the most common reason for euthanasia of adult dogs (45%). Low-cost or free desexing and identification programs targeted to areas and breeds contributing to high intake, and increased support services for owners at risk of surrendering their dog, should be trialed to determine their cost effectiveness in reducing shelter admissions and euthanasia.

    2005-01-01

    The Queensland Environmental Protection Agency monitored water quality at 133 sites in North Queensland waterways between Cooktown and Bundaburg from 1992 to 2001. Condition of the waterways was rated by comparing recent data with the Queensland Water Quality Guidelines. Long-term trends were analysed using a censored regression technique that incorporates the effects of flow, temperature, seasonality and allows for long-term non-linear trends. Many sites were in good condition; those in poor condition were usually impacted by point source discharges; those in moderate condition were usually impacted by agricultural land use. There were no consistent long-term trends across the whole region. Recommendations for future programs include incorporating pressure indicators, ensuring high standards of quality assurance, including covariates such as rainfall in trend assessment and continuing programs over more than 10 years to allow detection of trends due to changes in land-use.

    Polycystic kidney disease and related syndromes involve dysregulation of cell proliferation in conjunction with ciliary defects. The relationship between cilia and cell cycle is enigmatic, but it may involve regulation by the NIMA-family of kinases (Neks). We previously showed that the Nek Fa2p is important for ciliary function and cell cycle in Chlamydomonas. We now show that Fa2p localizes to an important regulatory site at the proximal end of cilia in both Chlamydomonas and a mouse kidney cell line. Fa2p also is associated with the proximal end of centrioles. Its localization is dynamic during the cell cycle, following a similar pattern in both cell types. The cell cycle function of Fa2p is kinase independent, whereas its ciliary function is kinase dependent. Mice with mutations in Nek1 or Nek8 have cystic kidneys; therefore, our discovery that a member of this phylogenetic group of Nek proteins is localized to the same sites in Chlamydomonas and kidney epithelial cells suggests that Neks play conserved roles in the coordination of cilia and cell cycle progression.

    The purpose is to answer the following research question: are the time-series data published by the Australian Bureau of Statistics for Queensland statistically the same as those of the Queensland Suicide Register? This question was answered by first modelling statistically, for males and females, the time series suicide data from these two sources for the period of data availability, 1994 to 2007 (14 observations). Fitted values were then derived from the 'best fit' equations, after rigorous diagnostic testing. The outliers in these data sets were addressed with pulse dummy variables. Finally, by applying the Wald test to determine whether or not the fitted values are the same, we determined whether, for males and females, these two data sets are the same or different. The study showed that the Queensland suicide rate, based on Queensland Suicide Register data, was greater than that based on Australian Bureau of Statistics data. Further statistical testing showed that the differences between the two data sets are statistically significant for 24 of the 28 pair-wise comparisons. The quality of Australia's official suicide data is affected by various practices in data collection. This study provides a unique test of the accuracy of published suicide data by the Australian Bureau of Statistics. The Queensland Suicide Register's definition of suicide applies a more suicidological, or medical/health, conception of suicide, and applies different practices of coding suicide cases, timing of data collection processes, etc. The study shows that 'difference' between the two data sets predominates, and is statistically significant; thus the extent of the under-reporting of suicide is not trivial. Given that official suicide data are used for many purposes, including policy evaluation of suicide prevention programmes, it is suggested that the system used in Queensland should be adopted by the rest of Australia too.

    The purpose of the study was to provide reference data for computer-aided joint space analysis based on a semi-automated and computer-aided diagnostic system for the measurement of metacarpal-phalangeal and proximal-interphalangeal finger joint widths; additionally, the determination of sex differences and the investigation of changes in joint width with age were evaluated. Eighty hundred and sixty-nine patients (351 female and 518 male) received radiographs of the hand for trauma and were screened for a host of conditions known to affect the joint spaces. All participants underwent measurements of joint space distances at the metacarpal-phalangeal articulation (JSD-MCP) from the thumb to the small finger and at the proximal-interphalangeal articulation (JSD-PIP) from the index finger to the small finger using computer-aided diagnosis technology with semi-automated edge detection. The study revealed an annual narrowing of the JSD of 0.6% for the JSD-MCP and for the JSD-PIP. Furthermore, the data demonstrated a notable age-related decrease in JSD, including an accentuated age-related joint space narrowing in women for both articulations. Additionally, males showed a significantly wider JSD-MCP (+11.1%) and JSD-PIP (+15.4%) compared with the female cohort in all age groups. Our data presented gender-specific and age-related normative reference values for computer-aided joint space analysis of the JSD-MCP and JSD-PIP that could be used to identify disease-related joint space narrowing, particularly in patients with osteoarthritis and rheumatoid arthritis commonly involving the peripheral small hand joints.

    Exports of tertiary education services have become a growth industry for the Queensland economy. Since a policy change in 1987 from an aid to a trade approach to overseas students, fee paying overseas students have risen from a mere 5.9 per cent of all overseas students in 1987, to 89.6 per cent in 1995. Exports of tertiary education services from the Queensland economy now rival wool and wheat in importance. A number of marketing and policy issues arise in the context of further change in th...

    2017-10-01

    This study aimed to investigate the curvilinear relationship between extent of telecommuting and work-related well-being (ie, burnout, work engagement, and cognitive stress complaints), as well as to test whether job characteristics act as explanatory mechanisms underlying this relationship. A sample of 878 employees from an international telecommunication company with a long history of telecommuting participated in a survey on psychosocial risk factors and well-being at work. Mediation path analyses were conducted to test the hypotheses. Social support from colleagues, participation in decision-making, task autonomy, and work-to-family conflict, but not extent of telecommuting, were directly related to work-related well-being. Extent of telecommuting was indirectly related to well-being via social support. Employers should invest in creating good work environments in general, among both telecommuters and nontelecommuters.

    During the June, 2000 quarter saleable coal production, exports and productivity all increased when compared to the previous June, quarter. The 1999/00 financial year was a record year in Queensland for coal production, exports and productivity. During this financial year the Foxleigh mine commenced producing and exporting coal, mainly into the PCI market. Shell announced in May 2000 the sale of its subsidiary company, Shell Coal, to Anglo American plc. In Queensland, these assets included majority interests in the Moranbah North, German Creek and callide mines and the undeveloped Theodore and Taroom coal deposits. Also in May, 2000 Westfarmers announced that the group had purchased the Curragh mine from Arco.

    Full Text Available Background/Aim. Aging is one of the most complex biological processes which probably affect structure and function of the enteric nerve system. However, there is not much available information on this topic, particularly in humans. The aim of this study was to investigate the influence of aging on the structure of the myenteric ganglia in the anterior wall of the human proximal duodenum. Methods. We examined the myenteric ganglia in the proximal duodenal anterior wall specimens obtained from 30 cadaver persons aged from 20 to 84 years. Tissue samples were classified into three age groups: 20-44, 45-64 and 65-84 years. After standard histological preparation, specimens were stained with HE, Cresyl Violet and AgNO3. Morphometric analysis of all the specimens, using a multipurpose test system M42, was performed. The data were subjected to the ttest. Results. The myenteric ganglia of very old humans contains an empty space, i.e. the respective parts of ganglia show a decreased number of neuron as compared to younger population. The average number of neuron per cm2 of the duodenum in the youngest people (20-44 years was 69,370 ± 1,750.00, in the people aged 45-64 years 69,211 ± 1,573.33, and in the oldest persons (65-84 years 57,951 ± 1,291.52. The loss of neurons in the oldest persons was 16.46%. The applied statistic test demonstrated a significant difference between the observed groups (p < 0.0001. Conclusion. Aging does not induce changes in size and surface of neurons in the ganglia, but it decreases the number of neurons. The nerve structures in the elderly are partly emptied of bodies of nerve cells (“empty ganglions”, which indicates the existence of changed myenteric ganglia in the duodenum. These changes could be related to the duodenum motility disorder associated with aging.

    Two key recovery experiences mediating the relationship between work demands and well-being are psychological detachment and relaxation over leisure time. The process of recovery from work-related stress plays an important role in maintaining well-being, but is poorly understood in cancer workers. The aim of this exploratory study was to examine the relationships of burnout, psychological well-being and work engagement with the recovery experiences of psychological detachment and relaxation in oncology staff. A cross sectional survey of 573 cancer workers in Queensland was conducted (response rate 56%). Oncology nurses (n = 211) represented the largest professional group. Staff completed surveys containing demographics and psychosocial questionnaires measuring burnout, psychological distress, work engagement and recovery experience. Multiple regression analyses were performed to identify explanatory variables which were independently associated with Recovery Experience Score (RES). There was a negative association between the RES and burnout (p = 0.002) as well as psychological distress (p 25 years was negatively correlated with RES as was having a post graduate qualification, being married or divorced, having carer commitments. Participating in strenuous exercise was associated with high recovery (p = 0.015). The two recovery experiences of psychological detachment and relaxation had a strong negative association to burnout and psychological well-being, but not work engagement. Further research needs to be undertaken to better understand if improving recovery experience reduces burnout and improves the well-being of cancer workers. Crown Copyright © 2014.

    Knobbe, Chris A; Stojanoska, Marija

    2017-11-01

    Age-related macular degeneration (AMD) is the leading cause of irreversible vision loss and blindness in developed nations. AMD is anticipated to affect 196 million people worldwide, by 2020. However, the etiology of this disease remains unknown. Aging, genetic, and environmental influences have generally been implicated as major etiologic factors. We sought to examine the hypothesis that consumption of the 'displacing foods of modern commerce,' which equate to processed, nutrient-deficient and potentially toxic foods, may be the primary and proximate cause of AMD. To evaluate this hypothesis, we ran correlative AMD prevalence data against well-known proxy markers of processed food consumption, namely, sugar and vegetable oils, in 25 nations. In twenty-one nations, published studies provided AMD prevalence data and in four Pacific Island nations, practicing ophthalmologists in the regions completed retrospective chart analyses to estimate AMD prevalence in their respective regions. To estimate AMD prevalence historically, an extensive review of published papers and ophthalmic literature was completed. This review indicates that, between the years 1851 and 1930, AMD was a medical rarity worldwide, which then rose modestly in prevalence in the 1930s in the U.S. and U.K, finally elevating to epidemic proportions by 1975 in the U.S. Numerous developed nations have followed suit in recent decades. Simultaneously, between approximately 1880 and 2009, processed, nutrient-deficient foods gradually supplanted and displaced whole, unprocessed, nutrient-dense foods in developed nations, such that by 2009, 63 percent of the American diet was made up of nutrient-deficient foods in the form of refined white flour, added sugars, vegetable oils, and artificially created trans fats. The correlative data in 25 nations shows that increasing sugar and polyunsaturated vegetable oil consumption is invariably associated with new onset or rising prevalence of AMD, generally within about

    2016-01-01

    Summary Background Proximal Hamstring Tendinopathy-related Sciatic Nerve Entrapment (PHTrSNE) is a neuropathy caused by fibrosis interposed between the semimembranosus tendon and the sciatic nerve, at the level of the ischial tuberosity. Methods Ultrasound-guided Intratissue Percutaneous Electrolysis (US-guided EPI) involves galvanic current transfer within the treatment target tissue (fibrosis) via a needle 0.30 to 0.33 mm in diameter. The galvanic current in a saline solution instantly develops the chemical process of electrolysis, which in turn induces electrochemical ablation of fibrosis. In this article, the interventional procedure is presented in detail, and both the strengths and limits of the technique are discussed. Results US-guided EPI eliminates the fibrotic accumulation that causes PHTrSNE, without the semimembranosus tendon or the sciatic nerve being directly involved during the procedure. The technique is however of limited use in cases of compression neuropathy. Conclusion US-guided EPI is a technique that is quick to perform, minimally invasive and does not force the patient to suspend their activities (work or sports) to make the treatment effective. This, coupled to the fact that the technique is generally well-tolerated by patients, supports use of US-guided EPI in the treatment of PHTrSNE. PMID:27900300

    Reverse shoulder arthroplasty (RSA) in fractures is especially indicated in patients of advanced age, although the influence of age on functional outcomes, health-related quality of life (HRQoL) and complication rate is unknown. We hypothesized that complication rate would decrease in the geriatric population because of their reduced activity, improving the perceived HRQoL. Retrospective study of 42 patients with proximal humeral fractures treated with RSA, divided into two groups: Patients in the ≥80y group had a lower total CMS, 33 vs 64 (p = 0.027). Mean active range of motion at 24 months 80y group was the most affected. The "pain/discomfort" item was lower for the two age groups than for the reference population. There were 9.5 % complications: one prosthesis dislocation, one periprosthetic fracture and two surgical wound haematoma. Our results indicate that age is a critical factor for RSA success. Lower functional outcomes have been obtained in patients older than 80y, although the EQ-5D results in our sample were similar or even better than the referred population. Level III.

    2017-01-01

    A popular method to estimate proximal/distal temperature (TPROX and TDIST) consists in calculating a weighted average of nine wireless sensors placed on pre-defined skin locations. Specifically, TPROX is derived from five sensors placed on the infra-clavicular and mid-thigh area (left and right) and abdomen, and TDIST from four sensors located on the hands and feet. In clinical practice, the loss/removal of one or more sensors is a common occurrence, but limited information is available on how this affects the accuracy of temperature estimates. The aim of this study was to determine the accuracy of temperature estimates in relation to number/position of sensors removed. Thirteen healthy subjects wore all nine sensors for 24 hours and reference TPROX and TDIST time-courses were calculated using all sensors. Then, all possible combinations of reduced subsets of sensors were simulated and suitable weights for each sensor calculated. The accuracy of TPROX and TDIST estimates resulting from the reduced subsets of sensors, compared to reference values, was assessed by the mean squared error, the mean absolute error (MAE), the cross-validation error and the 25th and 75th percentiles of the reconstruction error. Tables of the accuracy and sensor weights for all possible combinations of sensors are provided. For instance, in relation to TPROX, a subset of three sensors placed in any combination of three non-homologous areas (abdominal, right or left infra-clavicular, right or left mid-thigh) produced an error of 0.13°C MAE, while the loss/removal of the abdominal sensor resulted in an error of 0.25°C MAE, with the greater impact on the quality of the reconstruction. This information may help researchers/clinicians: i) evaluate the expected goodness of their TPROX and TDIST estimates based on the number of available sensors; ii) select the most appropriate subset of sensors, depending on goals and operational constraints.

    To investigate opinions and concerns of Gold Coast residents regarding fluoridation of community water supplies. Anonymous data were collected in four major shopping centers from approximately 500 Gold Coast residents. Eighty-one percent of participants were aware of the addition of fluoride to the water supply. More than half obtained information on water fluoridation through the print and electronic media. Sixty percent of respondents supported water fluoridation. The majority preferred the public and/or health professionals to have made the decision on water fluoridation rather than the government. The percentage of residents supporting water fluoridation was lower than that found in other Queensland, Australian, and worldwide surveys. In this study, only age and the highest level of education attained were factors significantly related to levels of support for water fluoridation. The Queensland Government's decision to implement water fluoridation without a referendum caused disquiet amongst some Gold Coast residents. Future public health initiatives therefore may be assisted by more consultation with, and involvement from, health professionals in the relevant fields. Public health campaigns may benefit more from interaction with the community in order to address their specific concerns. © 2012 Wiley Publishing Asia Pty Ltd.

    To define characteristics of vehicle crashes occurring on rural private property in north Queensland with an exploration of associated risk factors. Descriptive analysis of private property crash data collected by the Rural and Remote Road Safety Study. Rural and remote north Queensland. A total of 305 vehicle controllers aged 16 years or over hospitalised at Atherton, Cairns, Mount Isa or Townsville for at least 24 hours as a result of a vehicle crash. A structured questionnaire completed by participants covering crash details, lifestyle and demographic characteristics, driving history, medical history, alcohol and drug use and attitudes to road use. Overall, 27.9% of interviewees crashed on private property, with the highest proportion of private road crashes occurring in the North West Statistical Division (45%). Risk factors shown to be associated with private property crashes included male sex, riding off-road motorcycle or all-terrain vehicle, first-time driving at that site, lack of licence for vehicle type, recreational use and not wearing a helmet or seatbelt. Considerable trauma results from vehicle crashes on rural private property. These crashes are not included in most crash data sets, which are limited to public road crashes. Legislation and regulations applicable to private property vehicle use are largely focused on workplace health and safety, yet work-related crashes represent a minority of private property crashes in north Queensland.

    The pronator syndrome is a rare compression neuropathy of the median nerve. Ulnar head of the pronator teres muscle may cause compression at proximal forearm. Detailed morphologic and morphometric studies on the anatomy of the ulnar head of pronator teres is scarce. We dissected 112 forearms of fresh cadavers. We evaluated the morphology and morphometry of the ulnar head of pronator teres muscle. The average ulnar head width was 16.3±8.2mm. The median nerve passed anterior to the ulnar head at a distance of 50.4±10.7mm from the interepicondylar line. We classified the morphology of the ulnar head into 5 types. In type 1, the ulnar head was fibromuscular in 60 forearms (53.6%). In type 2, it was muscular in 23 forearms (20.5%). In type 3, it was just a fibrotic band in 18 forearms (16.1%). In type 4, it was absent in 9 forearms (8%). In type 5, the ulnar head had two arches in 2 forearms (1.8%). In 80 forearms (71.5%: types 1, 3, and 5), the ulnar head was either fibromuscular or a fibrotic band. Although the pronator syndrome is a rare compression syndrome, the ulnar head of pronator teres is reported as the major cause of entrapment in the majority of the cases. The location of the compression of the median nerve in relation to the ulnar head of pronator teres muscle and the morphology of the ulnar head is important for open or minimally-invasive surgical treatment.

    Since 1990 several airway devices have become available to assist in difficult intubation. Multiple surveys have assessed difficult airway equipment availability in international anaesthetic departments and emergency departments. The practice of GP anaesthetists is unique in both its multidisciplinary nature and geographical isolation. General practitioners performing general anaesthesia in rural and remote Queensland, Australia were surveyed to assess their access to difficult airway equipment and whether this was related to the remoteness of their location or attendance at continuing professional development activities. survey. proceduralists performing general anaesthesia in hospitals categorised as Rural, Remote and Metropolitan Area (RRMA) classification 4 to 7 inclusive were surveyed. data collected included demographic information, availability of airway management equipment, and attendance at continuing professional development activities. The received data was entered into a Microsoft Excel spreadsheet and analysed in Statistical Package for Social Sciences (SPSS Inc; Chicago, IL, USA) using the frequencies and crosstabs functions. The Fisher's exact test was used. A p-value of less than 0.10 was considered noteworthy and a p-value of less than 0.05 was considered to be significant. A statistical comparison was made between the known demographics of the target population and the survey responders. The known demographics were derived from the Health Workforce Queensland database and included age, gender, practice location and practitioner type. Seventy-nine surveys were distributed and 35 returned (response rate 44%). This represented 21 hospitals. There was no statistical difference between the target population and the survey responders in terms of age and gender. There was no statistical difference in terms of practice location, although the small percentage responding from RRMA 6 was notable. There was a statistically significant difference between the

    A new species of diplodactylid gecko in the genus Strophurus Fitzinger, from north Queensland, Australia, is described herein as Strophurus congoo sp. nov. It is a small, pale grey to tan, unpatterned or faintly striped gecko, resembling the phasmid geckos in appearance, habitat and behaviour. However, within Strophurus it is not closely related to the phasmid geckos. It is distinguished from all other Strophurus by a combination of even scalation, dull colouration, small size and short tail length. It is only known to occur in a restricted area of the northern Great Dividing Range, within the Einasleigh Uplands bioregion, in a relatively infertile area of rolling, largely granitic hills, and is only known from spinifex (Triodia) hummock grasslands in open woodland.

    Nannofossils section sign here described are from the middle Proterozoic Paradise Creek Formation, along Paradise Creek in northwestern Queensland, Australia. These fossils, in chert blebs associated with branched stromatolites, comprise cubic colonies analogous to living Eucapsis, a member of the blue-green algal family Chroococcaceae. The age of the enclosing rocks, bracketed by the ages of older and younger granitic events, is about 1.6 x 10(9) years. We record, therefore, a new chronological and biological datum in the currently accumulating sequence of pre-Paleozoic microbiotas.

    Full Text Available Background Bull riding is an increasingly popular and growing professional sport in Australia. This is the first national study that investigates bull riding-related injuries. Method A six-year retrospective study of patients admitted to Rockhampton Base Hospital with acute injuries sustained whilst bull riding. Patients were identified from the Rockhampton Hospital international coding system and surgical audit excel databases. Supporting information was found from patient chart review. Results Thirty-eight patients were admitted during the study. Injuries increased from 2008. The most common injuries were to limbs (52%, chest (15% and brain (10%. Life-threatening injuries were all caused by a direct kick or trampling by the bull; 5% of patients needed air transfer to Brisbane, and 10% to Rockhampton for their acute care. The only complication was infection of open wounds. The average hospital stay was 2.2 (range= 1-5, SD= 1.1 days and 64% of patients required operative intervention. Conclusion Patients that had been kicked or trampled should be identified as having potentially life-threatening injuries, and transferred for review at an appropriate facility. Due to the high risk of infection all contaminated wounds should be washed out formally and receive antibiotics. Protective equipment should be encouraged among riders.

    2013-01-01

    We investigated the applicability of the Gestalt principle of perceptual grouping by proximity in the haptic modality. To do so, we investigated the influence of element proximity on haptic contour detection. In the course of four sessions ten participants performed a haptic contour detection task in which they freely explored a haptic random dot display that contained a contour in 50% of the trials. A contour was defined by a higher density of elements (raised dots), relative to the background surface. Proximity of the contour elements as well as the average proximity of background elements was systematically varied. We hypothesized that if proximity of contour elements influences haptic contour detection, detection will be more likely when contour elements are in closer proximity. This should be irrespective of the ratio with the proximity of the background elements. Results showed indeed that the closer the contour elements were, the higher the detection rates. Moreover, this was the case independent of the contour/background ratio. We conclude that the Gestalt law of proximity applies to haptic contour detection. PMID:23762364

    To inform the development of an initiative designed to support the mental well-being of farmers in Queensland. Interactive focus groups. Rural and remote Queensland. Health professionals, farmers and representatives of organisations and agencies working with farmers. Determination of factors contributing to the declining mental health of rural landholders. Content material for inclusion into mental health first aid programs held for field officers. Key areas identified to contribute to the decline in mental health of farmers were: increasing isolation in its varying forms, the ongoing drought, increased government regulations and widening of the schism between urban and rural Australians. The issues that affect farmers are recognised to have a 'knock-on' effect on the people who interact with them. In particular, rural support organisations are concerned for the well-being of their staff, prompting some to begin to put protocols in place to address their staff need for mental health support. Additional mental health training of field officers that involves awareness, recognition, communication skills, understanding and empathy was recognised by participants to be beneficial. Training of field officers was considered to be of benefit to the support of farmers. An understanding of the various and diverse issues that rural landholders face should be a fundamental component of that training.

  15. Short note on a Pteranodontoid pterosaur (Pterodactyloidea) from western Queensland, Australia.

    2011-03-01

    Flying reptiles from Australia are very rare, represented mostly by isolated bones coming from the Early Cretaceous (Albian) Toolebuc Formation, which crops out in western Queensland. Among the first pterosaur specimens discovered from this deposit is a mandibular symphysis that some authors thought to have a particular affinity to species found in the Cambridge Greensand (Cenomanian) of England. It was further referred as a member of or closely related to one of the genera Ornithocheirus, Lonchodectes or Anhanguera. Here we redescribe this specimen, showing that it cannot be referred to the aforementioned genera, but represents a new species of Pteranodontoid (sensu Kellner 2003), here named Aussiedraco molnari gen. et sp. nov. It is the second named pterosaur from Australia and confirms that the Toolebuc deposits are so far the most important for our understanding of the flying reptile fauna of this country.

    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.

    The 2010-2011 Queensland floods resulted in the most deaths from a single flood event in Australia since 1916. This article analyses the information on these deaths for comparison with those from previous floods in modern Australia in an attempt to identify factors that have contributed to those deaths. Haddon's Matrix, originally designed for prevention of road trauma, offers a framework for understanding the interplay between contributing factors and helps facilitate a clearer understanding of the varied strategies required to ensure people's safety for particular flood types. Public reports and flood relevant literature were searched using key words 'flood', 'fatality', 'mortality', 'death', 'injury' and 'victim' through Google Scholar, PubMed, ProQuest and EBSCO. Data relating to reported deaths during the 2010-2011 Queensland floods, and relevant data of previous Australian flood fatality (1997-2009) were collected from these available sources. These sources were also used to identify contributing factors. There were 33 deaths directly attributed to the event, of which 54.5% were swept away in a flash flood on 10 January 2011. A further 15.1% of fatalities were caused by inappropriate behaviours. This is different to floods in modern Australia where over 90% of deaths are related to the choices made by individuals. There is no single reason why people drown in floods, but rather a complex interplay of factors. The present study and its integration of research findings and conceptual frameworks might assist governments and communities to develop policies and strategies to prevent flood injury and fatalities. © 2013 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

  18. Capacitive proximity sensor

    Science.gov (United States)

    Kronberg, James W.

    1994-01-01

    A proximity sensor based on a closed field circuit. The circuit comprises a ring oscillator using a symmetrical array of plates that creates an oscillating displacement current. The displacement current varies as a function of the proximity of objects to the plate array. Preferably the plates are in the form of a group of three pair of symmetric plates having a common center, arranged in a hexagonal pattern with opposing plates linked as a pair. The sensor produces logic level pulses suitable for interfacing with a computer or process controller. The proximity sensor can be incorporated into a load cell, a differential pressure gauge, or a device for measuring the consistency of a characteristic of a material where a variation in the consistency causes the dielectric constant of the material to change.

    Full Text Available The theatricality of urban encounters is above all a theatricality of distances which allow for the encounter. The absolute “strangeness” of the crowd (Simmel 1997: 74 expressed, in its purest form, in the absolute proximity of a crowded subway train, does not generally allow for any movements of approach, but only for nervous hostile reactions and submissive hypnotic gestures. Neither forced intersections in the course of pedestrians or vehicles, nor the instantaneous crossing of distances by the technology of live broadcasting and remote control give birth to places of encounter. In the forced proximity of the metropolitan crowd which haunted the city of the 19th and 20th century, as well as in the forced proximity of the tele-presence which haunts the dystopic prospect of the future “omnipolis” (Virilio 1997: 74, the necessary distance, which is the stage of an encounter between different instances of otherness, is dissipated.

    2015-03-20

    Species of the extinct family Dysmorphoptilidae with distinctly punctate and emarginate tegmina are one of the most characteristic elements of the hemipteran fauna of the three Queensland Triassic fossil insect-bearing formations-the Middle Triassic (Anisian) Gayndah Formation at Gayndah, the Late Triassic (Norian) Mount Crosby Formation at Mount Crosby, and the Late Triassic (Norian) Blackstone Formation at Mount Crosby and Dinmore. Eight species in five genera have been identified: Mesocixius triassicus Tillyard, 1919 (Denmark Hill), Mesocixius parvus (Evans) comb. nov., 1956 (Mount Crosby), Triassocixius australicus Tillyard, 1919 (Denmark Hill), Carsburgia knezouri gen. et sp. nov. (Dinmore), Dysmorphoptiloides elongata Evans, 1956 (Mount Crosby), Dysmorphoptiloides ellisi sp. nov. (Gayndah), Tennentsia princeps sp. nov. (Mount Crosby), and Tennentsia evansi sp. nov. (Gayndah). Synapomorphies are proposed to suggest that Triassocixius, Carsburgia, Dysmorphoptiloides and Tennentsia are monophyletic. Mesocixius may be paraphyletic, its two species sharing only apparently plesiomorphic characters. The limits and relationships of the over 15 described world genera of the Dysmorphoptilidae remain poorly known, but examination of the Queensland species has identified several characters which may be of cladistic value: the presence or absence of a strigil, the degree of tegmen emarginations and form of the resultant apical lobe, the presence and form of swellings on the claval margin, the pattern of tegmen punctation, the relativities of the primary forks of R and RA, the branching pattern of RA1, the branching and orientation of RA2,and the presence or absence of a fusions between RA and RP distally and between M and CuA basally.

    2010-01-01

    To investigate whether microfractures and alterations in the trabecular bone area are associated with catastrophic bi-axial proximal sesamoid bone fractures (PSBF). Proximal sesamoid bones (PSB) from 10 racehorses with PSBF and from 10 control racehorses without musculoskeletal injury were examined using the bulk basic fuchsin method. Bone histomorphometric and microfracture analysis was performed, and cases and controls compared using two-sample t-test, paired t-test, and Mann-Whitney U test. There was no significant difference in the microfracture density and the trabecular bone area between bones from case and control horses, and between fractured and non-fractured bones in case horses. Microfracture density was low in the areas of the PSB examined. Microfracture density was not significantly different between groups, indicating that propagation of micro-cracks is an unlikely predisposing pathologic alteration in PSBF in British racehorses. There was no significant difference in the bone surface area between groups, which one would expect if modelling, adaptation and an increase in bone density were associated with PSBF fracture in the case horses. Therefore, PSBF in the British racehorse does not appear to be associated with microfractures of the trabecular bone of the PSB. The PSB fractures might represent an acute monotonic fracture; however, the aetiology of the fractures remains unknown with additional research required.

    The present study explored the impact of random breath testing (RBT) on the attitudes, perceptions, and self-reported behavior of motorists in the Australian state of Queensland. Particular attention was given to how exposure to RBT impacted motorists' perceived risk of apprehension and self-reported behavior, relative to other variables of interest such as alcohol consumption. The study involved a telephone survey of 780 motorists drawn from throughout the state of Queensland. Participants were volunteers recruited from a random sample of all listed telephone numbers in the state, adjusted according to district population figures. The survey questionnaire collected information relating to the participants' socio-demographic characteristics, drinking and drunk driving behaviors, attitudes toward drunk driving and RBT, and experiences and perceptions of RBT. The analysis indicated that a large proportion of the sample had both observed RBT and been breath tested within the last six months and believed the practice served an important role in improving road safety. However, a considerable percentage also reported drunk driving at least once in the last six months without being detected, with further analysis indicating that the threat of apprehension associated with RBT did not appear to greatly influence their offending behavior. Rather, a higher frequency of alcohol consumption, combined with more favorable attitudes to drunk driving and lower levels of support for RBT, appeared to be associated with offending behavior. While the results confirm the high levels of exposure to RBT achieved in Queensland, the direct impact of recent exposure on drunk driving behavior appears less important than other factors such as alcohol consumption and attitudes to drunk driving and RBT. Further research is required to better understand how recent and lifetime exposure to RBT impacts on motorists' perceived risk of apprehension and subsequent drunk driving behavior.

    Changes in modern healthcare's provision, complexity, and workforce demands provide a compelling rationale for an increasing emphasis on leadership development at all levels of training within the medical profession. Undergraduate medical education has traditionally focused on the development of clinical acumen with little emphasis on the development of leadership skills or on the operational and systemic issues surrounding healthcare delivery. Incorporating leadership education and competencies presents a number of challenges to medical schools, including defining the subject area, determining the specific skills and knowledge bases that should constitute the basis of the program, and optimizing training to be integrated into the existing clinical curriculum. We present a case study of the Medical Leadership Program at The University of Queensland School of Medicine that runs concurrent to the undergraduate medical degree. We outline the inception of the program, its aims, participant selection, and program components and reflect on the program to date.

    Clinical outcomes for patients treated in public and private hospitals may be different. The aim of the study was to compare the characteristics and outcomes of patients receiving dialysis at public and private hospitals in Queensland. Incident adult dialysis patients in Queensland registered with the Australia and New Zealand Dialysis and Transplant Registry between 1999 and 2009 were classified by dialysis modality at either a public or private hospital. Outcomes were dialysis patient characteristics and survival. Three thousand, three hundred and ten patients commenced dialysis in public hospitals, 1939 haemodialysis (HD) and 1371 peritoneal dialysis (PD). Seven hundred and ninety-three patients commenced dialysis in private hospitals, 757 HD and 36 PD. Compared with public HD, private HD patients were older, had more coronary artery disease and less diabetes, and were more likely to live in an urban area. Public HD patients were more likely to be obese and referred late to a nephrologist. Nearly all indigenous patients were managed in public hospitals. Private patients were more likely to have an arteriovenous fistula or graft at first HD (P < 0.001) but not after excluding late referrals (P = 0.09). Public hospitals provided longer HD sessions and more HD hours per week for all age groups except 75+ years. Compared with public hospital HD, patient survival adjusted for multiple variables was comparable for private hospital HD (hazard ratio 1.20 (95% confidence interval 0.98-1.46, P = 0.07)) but worse for public PD (hazard ratio 1.14 (95% confidence interval 1.05-1.24, P = 0.002)). Private HD patients are older and less likely to be diabetic than public patients. Patient survival is worse for public PD than public HD. © 2012 The Authors.

    1988-01-01

    A picornavirus was isolated from various life stages of the Queensland fruit fly, Dacus tryoni. This virus, Queensland fruit fly virus (QFFV) has virions with a diameter of 30 nm and a sedimentation coefficient of 178 S. One third of the particles in preparations were empty capsids or natural top component (NTC) with a sedimentation coefficient of 95 S. The buoyant density (rho) of virions and NTC in CsCl was 1.34 and 1.30 g/ml respectively; small amounts of a dense component (rho = 1.45 g/ml) were also detected. The capsid contained three major protein species of molecular weight (mol.wt.) 41,700, 36,500, and 31,300, in approximately equimolar proportions. NTC contained three major species of mol. wt. 44,700, 41,700, and 31,300. The nucleic acid present only in the bottom component virions was RNA and comprised about 30% of the particle weight and had a mol. wt of 2.88 kd, contained a poly(A) tract, and had a base ratio: G = 20; A = 32; C = 15; U = 33. The mol. wt. of the virion was estimated to be approximately equal to 9.5 kd. When virions were heated at 56 degrees C and above, they converted into artificial top component (ATC), which had the same protein composition as the virion when analysed by SDS-PAGE. In immunodiffusion tests the virions and NTC were indistinguishable, but a minor difference in antigenicity was detected between the virions and ATC. Virions were stable between pH 3 and 9 inclusive, and between 5 and 7 in the presence of 0.14 M NaCl. Immunodiffusion tests showed that QFFV was serologically unrelated to a range of picornaviruses as well as an unclassified virus isolated from the Mediterranean fruit fly, Ceratitis capitata. The data show that QFFV is probably a member of the Picornaviridae, genus Enterovirus.

    Full Text Available About 300 cod (Gadus morhua were sampled on three different sites of different proximity to grey seals (Halichoerus grypus, which are the most important final host for Pseudoterranova krabbei, off Drangar, Northwest Iceland, in the summer of 2004. Cod caught at each station were grouped into four sizes: (1 40–54 cm, (2 55–59 cm, (3 60–69 cm and, (4 >70 cm. Difference in prevalence between catch-sites were analyzed by a binary logistic regression model. Abundance, and density were investigated with multiple regressions. As expected prevalence, abundance and density of Pseudoterranova larvae were highest in the fish caught closest to shore, which was also in closest proximity to grey seal colonies and in the shallowest waters. In the closest proximity to grey seal colonies and in the shallowest water, the prevalence and abundance of sealworm larvae increased with increased length of fish. Finally, the density of Pseudoterranova larvae in cod declined exponentially with depth: 50% at 65 meters and almost zero at 210 meters. In the paper these observations were discussed in relation to sealworm eggs dispersal, depth gradient off the coast, temperature tolerance of the sealworm ovum, and behavioral types of Icelandic cod.

    What is the central question of this study? Although SGLT2 inhibitors represent a promising treatment for patients suffering from diabetic nephropathy, the influence of metabolic disruption on the expression and function of glucose transporters is largely unknown. What is the main finding and its importance? In vivo models of metabolic disruption (Goto-Kakizaki type II diabetic rat and junk-food diet) demonstrate increased expression of SGLT1, SGLT2 and GLUT2 in the proximal tubule brush border. In the type II diabetic model, this is accompanied by increased SGLT- and GLUT-mediated glucose uptake. A fasted model of metabolic disruption (high-fat diet) demonstrated increased GLUT2 expression only. The differential alterations of glucose transporters in response to varying metabolic stress offer insight into the therapeutic value of inhibitors. SGLT2 inhibitors are now in clinical use to reduce hyperglycaemia in type II diabetes. However, renal glucose reabsorption across the brush border membrane (BBM) is not completely understood in diabetes. Increased consumption of a Western diet is strongly linked to type II diabetes. This study aimed to investigate the adaptations that occur in renal glucose transporters in response to experimental models of diet-induced insulin resistance. The study used Goto-Kakizaki type II diabetic rats and normal rats rendered insulin resistant using junk-food or high-fat diets. Levels of protein kinase C-βI (PKC-βI), GLUT2, SGLT1 and SGLT2 were determined by Western blotting of purified renal BBM. GLUT- and SGLT-mediated d-[(3) H]glucose uptake by BBM vesicles was measured in the presence and absence of the SGLT inhibitor phlorizin. GLUT- and SGLT-mediated glucose transport was elevated in type II diabetic rats, accompanied by increased expression of GLUT2, its upstream regulator PKC-βI and SGLT1 protein. Junk-food and high-fat diet feeding also caused higher membrane expression of GLUT2 and its upstream regulator PKC

    The purpose of this study was to evaluate the relationship between the bone quality of the humeral head measured by CT multiplanar reconstruction images (MPR) and the stability of nail or plate fixation and to compare the clinical outcomes of these procedures in patients with proximal humeral fractures. Thirty-six consecutive patients (nail group: n = 18, plate group: n = 18) were investigated. In nail group, 14 cases were classified as two-part fractures, three cases were classified as three-part fractures and one case was classified as four-part fractures. In plate group, three cases were classified as two-part fractures, nine cases were classified as three-part fractures and six cases were classified as four-part fractures. Both clinical and radiological outcomes were assessed. In addition, the percentage of trabecular bone volume of the humeral head was calculated using preoperative CT-MPR images. Three patients in the nail group underwent reoperation. In contrast, no patients in the plate group underwent reoperation. In nail group, six of 18 (33%) patients demonstrated poor results (three underwent reoperation, and three had varus displacements >10º) and had bone volume percentages (axial image) that were significantly lower than those observed in the patients with good results. The cutoff point of trabecular bone volume required to obtain satisfactory results after surgical treatment using intramedullary nail was 78%. The results of this study suggest that the bone volume of the humeral head calculated using CT-MPR images provides useful information, in addition to the type of fracture, when selecting fixation devices for osteosynthesis of proximal humeral fracture.

  12. Ammonia transport in the proximal tubule.

    1990-01-01

    The transport of ammonia in the proximal tubule is a complex interaction of a number of processes. Ammonia transport in the proximal tubule is clearly bidirectional; ammonia is secreted into the early proximal tubule lumen, but later in the proximal tubule, efflux out of the lumen may result in net ammonia reabsorption. Two mechanisms of ammonia transport have clearly been established: NH3 diffusion and NH4+ transport on the Na(+)-H+ exchanger. The relative contribution of these pathways to ammonia transport is still unsettled. Other pathways for ammonia transport, particularly NH4+ efflux out of the lumen, may be important as well. A variety of factors may modulate ammonia transport: plasma, cell and luminal pH, luminal flow rate, luminal potassium, and angiotensin II. Each of these factors also alters ammonia production rates and in most circumstances, ammonia transport appears to follow ammonia production rates.

    2012-10-01

    Vocational Education and Training (VET) is an essential tool for providing waste management and recycling workers with the necessary skills and knowledge needed to beneficially influence their own employment and career development; and to also ensure productivity and safe working conditions within the organisations in which they are employed. Current training opportunities within Queensland for the sector are limited and not widely communicated or marketed; with other States, particularly Victoria and New South Wales, realising higher numbers of VET enrollments for waste management courses. This paper presents current VET opportunities and trends for the Queensland waste management sector. Results from a facilitated workshop to identify workforce requirements and future training needs organised by the Waste Contractors and Recyclers Association of Queensland (WCRAQ) are also presented and discussion follows on the future training needs of the industry within Queensland.

    2017-02-01

    This study aimed (i) to determine the change in the number of government-funded nutrition positions following structural and political reforms and (ii) to describe the remaining workforce available to do nutrition prevention work, including student placements, in Queensland. Positions funded by the Queensland government were counted using departmental human resource data and compared with data collected 4 years earlier. Positions not funded by the government were identified using formal professional networks and governance group lists. Both groups were sent an online survey that explored their position name, funding source, employer, qualifications, years of experience, work in prevention and ability to supervise students. There was a 90% reduction in the number of nutrition prevention positions funded by the government between 2009 (137 full time equivalents (FTE)) and 2013 (14 FTE). In 2013, 313 specialist (n = 92) and generalist (n = 221) practitioners were identified as potentially working in nutrition prevention throughout Queensland. A total of 30 permanent FTEs indicated over 75% of their work focused on prevention. This included the 14 FTE funded by the Queensland government and an additional 16 FTE from other sectors. Generalists did not consider themselves part of the nutrition workforce. Queensland experienced an extreme reduction in its nutrition prevention workforce as a result of political and structural reforms. This disinvestment by the Queensland government was not compensated for by other sectors, and has left marked deficits in public health nutrition capacity, including student placements. © 2015 Dietitians Association of Australia.

    The effects of weather variability on seasonal influenza among different age groups remain unclear. The comparative study aims to explore the differences in the associations between weather variability and seasonal influenza, and growth rates of seasonal influenza epidemics among different age groups in Queensland, Australia. Three Bayesian spatiotemporal conditional autoregressive models were fitted at the postal area level to quantify the relationships between seasonal influenza and monthly minimum temperature (MIT), monthly vapor pressure, school calendar pattern, and Index of Relative Socio-Economic Advantage and Disadvantage for 3 age groups (age, respectively, while the average increase in the monthly influenza cases was 14.6% (95% CI, 9.0%-21.0%), 12.1% (95% CI, 8.8%-16.1%), and 9.2% (95% CI, 1.4%-16.9%) for a 1-hPa increase in vapor pressure. Weather variability appears to be more influential on seasonal influenza transmission in younger (0-14) age groups. The growth rates of influenza at postal area level were relatively small for older (≥65) age groups in Queensland, Australia.

    2017-01-01

    Participation in extreme sports has been linked to personal transformations in everyday life. Descriptions of lived experience resulting from transformative experiences are limited. Proximity flying, a relatively new discipline involving BASE jumping with a wingsuit where participants fly close to solid structures, is arguably one of the most extreme of extreme sports. The aim of this paper, part of a larger phenomenological study on the lived experience of proximity flying, is to explicate the ways in which participating in proximity flying influences the everyday lives of participants. Interpretative phenomenological analysis was used to explicate the lived experience of six proximity pilots. An analysis of interview transcripts revealed three significant themes describing the lived experience of participants. First, experiences of change were described as positive and skills developed through proximity flying were transferable into everyday life. Second, transformative experiences were considered fundamental to participants’ perspectives on life. Third, experience of transformation influenced their sense of personal identity and facilitated flourishing in other aspects of everyday life. Participants were clear that their experiences in proximity flying facilitated a profound process of transformation which manifest as changes in everyday capabilities and behaviors, values and sense of identity.

    Research shows that stress in pregnancy has powerful and enduring effects on many facets of child development, including increases in behavior problems and neurodevelopmental disorders. Theory of mind is an important aspect of child development that is predictive of successful social functioning and is impaired in children with autism. A number of factors related to individual differences in theory of mind have been identified, but whether theory of mind development is shaped by prenatal events has not yet been examined. In this study we utilized a sudden onset flood that occurred in Queensland, Australia in 2011 to examine whether disaster-related prenatal maternal stress predicts child theory of mind and whether sex of the child or timing of the stressor in pregnancy moderates these effects. Higher levels of flood-related maternal subjective stress, but not objective hardship, predicted worse theory of mind at 30 months (n=130). Further, maternal cognitive appraisal of the flood moderated the effects of stress in pregnancy on girls' theory of mind performance but not boys'. These results illuminate how stress in pregnancy can shape child development and the findings are discussed in relation to biological mechanisms in pregnancy and stress theory.

    Sarsha Yap

    Full Text Available Animals that have a long pre-reproductive adult stage often employ mechanisms that minimize aging over this period in order to preserve reproductive lifespan. In a remarkable exception, one tephritid fruit fly exhibits substantial pre-reproductive aging but then mitigates this aging during a diet-dependent transition to the reproductive stage, after which life expectancy matches that of newly emerged flies. Here, we ascertain the role of nutrients, sexual maturation and mating in mitigation of previous aging in female Queensland fruit flies. Flies were provided one of three diets: 'sugar', 'essential', or 'yeast-sugar'. Essential diet contained sugar and micronutrients found in yeast but lacked maturation-enabling protein. At days 20 and 30, a subset of flies on the sugar diet were switched to essential or yeast-sugar diet, and some yeast-sugar fed flies were mated 10 days later. Complete mitigation of actuarial aging was only observed in flies that were switched to a yeast-sugar diet and mated, indicating that mating is key. Identifying the physiological processes associated with mating promise novel insights into repair mechanisms for aging.

    Mandatory bicycle helmet laws have been found to increase helmet wearing rates in Australia and internationally. However, much of the research on factors influencing compliance with the Australian helmet laws is dated or focuses on commuters and city areas only. To address this gap, video recordings of bicycle riders were undertaken at 17 sites across Queensland, Australia, representing a mixture of on- and off-road locations, speed limits and regions. Helmet status was able to be determined for 98% of riders observed. The level of compliance with the laws was very high, with 98.3% of the more than 27,000 riders observed wearing helmets. Riders riding on roads were less compliant than those riding on bicycle paths, but no significant differences were observed between the school-holiday and school-term periods. Among the on-road riders, boys were less compliant than girls and overall children were less compliant than adults. Higher compliance levels were found for group riders, road bike riders, lycra-clad riders, during morning hours, and on 50km/h or lower speed limit roads. While the overall level of compliance was very high, certain subgroups were identified as a possible focus for interventions to further improve the compliance level, for example children (particularly boys) riding mountain bikes away from groups during the afternoon hours on 60km/h roads.

    The purpose of this study is to explore the levels of interest among Indigenous people with cancer in identifying cancer risk in their family and seeking genetic counselling/testing. A cross-sectional survey of Indigenous cancer patients recruited from four major treating hospitals in Queensland. Participants' family history of cancer and interest in genetic counselling/testing was sought using a structured questionnaire. Overall, 73.0% of 252 participants reported having a family history of cancer; of those, 52.8% had at least one first-degree relative with cancer. A total of 68.3% of participants indicated concern about relatives being affected by cancer and 54.4% of participants indicated they would like to assess the cancer risk in their family with a specialist. Concern was associated with willingness to discuss the risk of cancer with a specialist (pIndigenous cancer patients do have a family history of cancer and appear willing to undergo genetic counselling/investigation. It is of great concern that this population could miss the benefits of the technological advances in health care, creating a much larger disparity in health outcomes. Health service providers should not assume that Indigenous cancer patients will not follow their recommendations when referred to genetic counselling/investigation services. © 2014 Public Health Association of Australia.

  5. Dwarfism and feeding behaviours in Oligo–Miocene crocodiles from Riversleigh, northwestern Queensland, Australia

    Directory of Open Access Journals (Sweden)

    Michael Stein

    2016-02-01

    Full Text Available Instances of dwarfism in the fossil record are of interest to palaeontologists because they often provide insight into aspects of palaeoecology. Fossil species of Australian-Pacific mekosuchine genus Mekosuchus have been described as dwarf, primarily terrestrial crocodiles, in contrast with the nearly ubiquitous semi-aquatic habitus of extant crocodilians (Willis 1997. This hypothesis has been difficult to test because of limited knowledge of the cranial and postcranial skeleton of extinct taxa and the continuous nature of crocodilian growth. New crocodilian vertebral material from Riversleigh, northwestern Queensland, tentatively referred to Mekosuchus whitehunterensis Willis, 1997, displays morphological maturity indicative of adult snout-vent length little over a half-meter, proportionally smaller than extant dwarf taxa. Further, this material displays morphology that indicates a relatively large epaxial neck musculature for its body-size. These attributes suggest this dwarf mekosuchine employed unusual feeding behaviours. The ability to perform normal death-roll, de-fleshing behaviours would be limited in a mekosuchine of such small size. Given the powerful neck muscles and other anatomical features, it is more likely that this mekosuchine killed and/or dismembered its prey using a relatively forceful lifting and shaking of the head.

    Full Text Available Flying reptiles from Australia are very rare, represented mostly by isolated bones coming from the Early Cretaceous (Albian Toolebuc Formation, which crops out in western Queensland. Among the first pterosaur specimens discovered from this deposit is a mandibular symphysis that some authors thought to have a particular affinity to species found in the Cambridge Greensand (Cenomanian of England. It was further referred as a member of or closely related to one of the genera Ornithocheirus, Lonchodectes or Anhanguera. Here we redescribe this specimen, showing that it cannot be referred to the aforementioned genera, but represents a new species of Pteranodontoid (sensu Kellner 2003, here named Aussiedraco molnari gen. et sp. nov. It is the second named pterosaur from Australia and confirms that the Toolebuc deposits are so far the most important for our understanding of the flying reptile fauna of this country.Répteis voadores da Austrália são muito raros e, na maioria dos casos, representados por ossos isolados procedentes da Formação Toolebuc (Cretáceo, Albiano, da região leste de Queensland.

    Instability of the hip is the most common mode of failure after reconstruction with a proximal femoral arthroplasty (PFA) using an endoprosthesis after excision of a tumour. Small studies report improved stability with capsular repair of the hip and other techniques, but these have not been investigated in a large series of patients. The aim of this study was to evaluate variables associated with the patient and the operation that affect post-operative stability. We hypothesised an association between capsular repair and stability. In a retrospective cohort study, we identified 527 adult patients who were treated with a PFA for tumours. Our data included demographics, the pathological diagnosis, the amount of resection of the abductor muscles, the techniques of reconstruction and the characteristics of the implant. We used regression analysis to compare patients with and without post-operative instability. A total of 20 patients out of 527 (4%) had instability which presented at a mean of 35 days (3 to 131) post-operatively. Capsular repair was not associated with a reduced rate of instability. Bivariate analysis showed that a posterolateral surgical approach (odds ratio (OR) 0.11, 95% confidence interval (CI) 0.02 to 0.86) and the type of implant (p = 0.046) had a significant association with reduced instability; age > 60 years predicted instability (OR 3.17, 95% CI 1.00 to 9.98). Multivariate analysis showed age > 60 years (OR 5.09, 95% CI 1.23 to 21.07), female gender (OR 1.73, 95% CI 1.04 to 2.89), a malignant primary bone tumour (OR 2.04, 95% CI 1.06 to 3.95), and benign condition (OR 5.56, 95% CI 1.35 to 22.90), but not metastatic disease or soft-tissue tumours, predicted instability, while a posterolateral approach (OR 0.09, 95% CI 0.01 to 0.53) was protective against instability. No instability occurred when a synthetic graft was used in 70 patients. Stability of the hip after PFA is influenced by variables associated with the patient, the pathology, the

    Mosquito-borne diseases are climate sensitive and there has been increasing concern over the impact of climate change on future disease risk. This paper projected the potential future risk of Barmah Forest virus (BFV) disease under climate change scenarios in Queensland, Australia. We obtained data on notified BFV cases, climate (maximum and minimum temperature and rainfall), socio-economic and tidal conditions for current period 2000-2008 for coastal regions in Queensland. Grid-data on future climate projections for 2025, 2050 and 2100 were also obtained. Logistic regression models were built to forecast the otential risk of BFV disease distribution under existing climatic, socio-economic and tidal conditions. The model was applied to estimate the potential geographic distribution of BFV outbreaks under climate change scenarios. The predictive model had good model accuracy, sensitivity and specificity. Maps on potential risk of future BFV disease indicated that disease would vary significantly across coastal regions in Queensland by 2100 due to marked differences in future rainfall and temperature projections. We conclude that the results of this study demonstrate that the future risk of BFV disease would vary across coastal regions in Queensland. These results may be helpful for public health decision making towards developing effective risk management strategies for BFV disease control and prevention programs in Queensland.

    We study the fuzzy soft proximity spaces in Katsaras's sense. First, we show how a fuzzy soft topology is derived from a fuzzy soft proximity. Also, we define the notion of fuzzy soft δ-neighborhood in the fuzzy soft proximity space which offers an alternative approach to the study of fuzzy soft proximity spaces. Later, we obtain the initial fuzzy soft proximity determined by a family of fuzzy soft proximities. Finally, we investigate relationship between fuzzy soft proximities and proximities. PMID:25793224

    2017-03-01

    To assess the relationship between vision and reading outcomes in Indigenous and non-Indigenous schoolchildren to determine whether vision problems are associated with lower reading outcomes in these populations. Vision testing and reading assessments were performed on 508 Indigenous and non-Indigenous schoolchildren in Queensland, Australia divided into two age groups: Grades 1 and 2 (6-7 years of age) and Grades 6 and 7 (12-13 years of age). Vision parameters measured included cycloplegic refraction, near point of convergence, heterophoria, fusional vergence range, rapid automatized naming, and visual motor integration. The following vision conditions were then classified based on the vision findings: uncorrected hyperopia, convergence insufficiency, reduced rapid automatized naming, and delayed visual motor integration. Reading accuracy and reading comprehension were measured with the Neale reading test. The effect of uncorrected hyperopia, convergence insufficiency, reduced rapid automatized naming, and delayed visual motor integration on reading accuracy and reading comprehension were investigated with ANCOVAs. The ANCOVAs explained a significant proportion of variance in both reading accuracy and reading comprehension scores in both age groups, with 40% of the variation in reading accuracy and 33% of the variation in reading comprehension explained in the younger age group, and 27% and 10% of the variation in reading accuracy and reading comprehension, respectively, in the older age group. The vision parameters of visual motor integration and rapid automatized naming were significant predictors in all ANCOVAs (P reading results were explained by reduced visual motor integration and rapid automatized naming results. Both reduced rapid automatized naming and visual motor integration were associated with poorer reading outcomes in Indigenous and non-Indigenous children. This is an important finding given the recent emphasis placed on Indigenous children

    Prescott, J.R. [Adelaide Univ., SA (Australia)

    1997-12-31

    In a previous paper (Tejan-Kella et al Aust J. Soil Res. 28, 465, 1990), thermoluminescence (TL) dates were presented for a soil horizon at five sites in a chronosequence of freely-drained podzols at Cooloola and North Stradbroke Island, Queensland. The TL ages followed the expected order based on geomorphological evidence; and the TL age of 120 {+-}11 ka for the Amity dune on North Stradbroke Island agreed with uranium series dates for underlying coral recovered during sand mining. Nevertheless, several features of the TL results gave rise to some concern and were noted in the above mentioned paper. Specifically, the apparent TL age of 11 {+-} 2 ka for the Kings Bore site was widely at variance with the inferred age of about 0.5 ka based on geomorphological and soil profile evidence. Further, an apparent TL age of about 8 ka was found for samples from the Carlo sand blow. The Carlo samples were taken at mean depths of 1.0 m and 1.5 m from within the advancing toe of the dune, which is obviously mobile since it is encroaching on living vegetation. The time since last exposure to sunlight could scarcely exceed a decade. New measurements are reported, designed to resolve the former discrepancies. All sites have been re-dated, together with a new one, CA5S/1 (Chalambar) and a reduced value have been obtained.

    Technology alone cannot address the challenges of how societies, communities, and individuals understand water accessibility, water management, and water consumption, particularly under extreme conditions like floods and droughts. At the community level, people are increasingly aware challenges related to responses to and impacts of extreme water events. This research begins with an assessment of social and political capacities of communities in two Commonwealth jurisdictions, Queensland, Australia and Saskatchewan, Canada, in response to major flooding events. The research further reviews how such capacities impact community engagement to address and mitigate risks associated with extreme water events and provides evidence of key gaps in skills, understanding, and agency for addressing impacts at the community level. Secondary data were collected using template analysis to elucidate challenges associated with education (formal and informal), social and political capacity, community ability to respond appropriately, and formal government responses to extreme water events in these two jurisdictions. The results indicate that enhanced community engagement alongside elements of an empowerment model can provide avenues for identifying and addressing community vulnerability to negative impacts of flood and drought.

    Australian snubfin and Indo-Pacific humpback dolphins co-occur throughout most of their range in coastal waters of tropical Australia. Little is known of their ecology or acoustic repertoires. Vocalizations from humpback and snubfin dolphins were recorded in two locations along the Queensland coast during 2008 and 2010 to describe their vocalizations and evaluate the acoustic differences between these two species. Broad vocalization types were categorized qualitatively. Both species produced click trains burst pulses and whistles. Principal component analysis of the nine acoustic variables extracted from the whistles produced nine principal components that were input into discriminant function analyses to classify 96% of humpback dolphin whistles and about 78% of snubfin dolphin calls correctly. Results indicate clear acoustic differences between the vocal whistle repertoires of these two species. A stepwise routine identified two principal components as significantly distinguishable between whistles of each species: frequency parameters and frequency trend ratio. The capacity to identify these species using acoustic monitoring techniques has the potential to provide information on presence/absence, habitat use and relative abundance for each species.

  16. Proximal tubular hypertrophy and enlarged glomerular and proximal tubular urinary space in obese subjects with proteinuria.

    Directory of Open Access Journals (Sweden)

    Ana Tobar

    Full Text Available BACKGROUND: Obesity is associated with glomerular hyperfiltration, increased proximal tubular sodium reabsorption, glomerular enlargement and renal hypertrophy. A single experimental study reported an increased glomerular urinary space in obese dogs. Whether proximal tubular volume is increased in obese subjects and whether their glomerular and tubular urinary spaces are enlarged is unknown. OBJECTIVE: To determine whether proximal tubules and glomerular and tubular urinary space are enlarged in obese subjects with proteinuria and glomerular hyperfiltration. METHODS: Kidney biopsies from 11 non-diabetic obese with proteinuria and 14 non-diabetic lean patients with a creatinine clearance above 50 ml/min and with mild or no interstitial fibrosis were retrospectively analyzed using morphometric methods. The cross-sectional area of the proximal tubular epithelium and lumen, the volume of the glomerular tuft and of Bowman's space and the nuclei number per tubular profile were estimated. RESULTS: Creatinine clearance was higher in the obese than in the lean group (P=0.03. Proteinuria was similarly increased in both groups. Compared to the lean group, the obese group displayed a 104% higher glomerular tuft volume (P=0.001, a 94% higher Bowman's space volume (P=0.003, a 33% higher cross-sectional area of the proximal tubular epithelium (P=0.02 and a 54% higher cross-sectional area of the proximal tubular lumen (P=0.01. The nuclei number per proximal tubular profile was similar in both groups, suggesting that the increase in tubular volume is due to hypertrophy and not to hyperplasia. CONCLUSIONS: Obesity-related glomerular hyperfiltration is associated with proximal tubular epithelial hypertrophy and increased glomerular and tubular urinary space volume in subjects with proteinuria. The expanded glomerular and urinary space is probably a direct consequence of glomerular hyperfiltration. These effects may be involved in the pathogenesis of obesity-related

The provision of CE and other vocational services in Queensland between 1996 and 2002 is the subject of this paper. Methods The Chiropractic & Osteopathic College of Australasia (COCA implemented a plan, which involved continuing education, with speakers from a broad variety of health provider areas; and the introduction of the concepts of evidence-based practice. The plan also involved building membership. Results Membership of COCA in Queensland grew from 3 in June 1996 to 167 in 2002. There were a total of 25 COCA symposia in the same period. Evidence-based health care was introduced and attendees were generally satisfied with the conferences. Discussion The development of a vocational body (COCA for chiropractors and osteopaths in Queensland was achieved. Registrants in the field have supported an organisation that concentrates on the vocational aspects of their practice.

    Caucasian renal transplant recipients living in Queensland, Australia, have the highest risk of nonmelanoma skin cancer in the world. To determine clinical and environmental factors associated with posttransplantation nonmelanoma skin cancer in Queensland. 361 Caucasian adult recipients completed a structured interview and full skin examination. Skin cancer details were obtained from hospital records. Squamous cell carcinoma was strongly associated with blue or hazel eyes, time resident in a hot climate, and pretransplantation squamous cell carcinoma; tumor numbers were associated with birth in a hot climate, childhood sunburn, pretransplantation actinic keratoses, and smoking. The risk of basal cell carcinoma was strongly associated with acute or intermittent sun exposure during childhood and pretransplantation basal cell carcinoma; numbers were associated with blue or hazel eyes, time spent living in a hot climate, and male gender. Clinical and environmental factors can be used to identify recipients at risk of nonmelanoma skin cancer in Queensland.

    2015-07-24

    A new species of blind snake is described from south-eastern Queensland, eastern Australia. Anilios insperatus sp. nov. differs from all of its congeners in having:16 scales around the body; 442 paravertebral scales; snout slightly trilobed from above and bluntly angular in profile; small, inconspicuous eyes, located within the ocular scale at its junction with the preocular and the supraocular scales; and uniform light colouration. The unique specimen was collected from pasture that was formally Queensland regional ecosystem 12.8.24, a eucalypt dominated ecosystem currently listed as endangered. The site is less than 100 km from Queensland's capital, Brisbane. Given the locality, habitat and absence of additional specimens, the species is probably of conservation concern.

    In 2002/03 the Queensland Government responded to high rates of alcohol-related harm in discrete Indigenous communities by implementing alcohol management plans (AMPs), designed to include supply and harm reduction and treatment measures. Tighter alcohol supply and carriage restrictions followed in 2008 following indications of reductions in violence and injury. Despite the plans being in place for over a decade, no comprehensive independent review has assessed to what level the designed aims were achieved and what effect the plans have had on Indigenous community residents and service providers. This study will describe the long-term impacts on important health, economic and social outcomes of Queensland's AMPs. The project has two main studies, 1) outcome evaluation using de-identified epidemiological data on injury, violence and other health and social indicators for across Queensland, including de-identified databases compiled from relevant routinely-available administrative data sets, and 2) a process evaluation to map the nature, timing and content of intervention components targeting alcohol. Process evaluation will also be used to assess the fidelity with which the designed intervention components have been implemented, their uptake and community responses to them and their perceived impacts on alcohol supply and consumption, injury, violence and community health. Interviews and focus groups with Indigenous residents and service providers will be used. The study will be conducted in all 24 of Queensland's Indigenous communities affected by alcohol management plans. This evaluation will report on the impacts of the original aims for AMPs, what impact they have had on Indigenous residents and service providers. A central outcome will be the establishment of relevant databases describing the parameters of the changes seen. This will permit comprehensive and rigorous surveillance systems to be put in place and provided to communities empowering them with the

    A new species of diplodactylid gecko in the genus Strophurus Fitzinger, from central Queensland, Australia, is described herein as Strophurus trux sp. nov. It is similar to the recently described Strophurus congoo Vanderduys from north Queensland and apparently shares a habitat preference for Triodia hummock open woodlands. It is notably different from the latter in possessing a vivid yellow to golden eye. It is only known from one small area of the Brigalow Belt Bioregion, although it is expected to occur more widely than the one area in which it has been found. It is likely that it is endemic to the Brigalow Belt Bioregion.

    Proximal radioulnar synostosis is a rare upper limb malformation. The elbow is first identifiable at 35 days (after conception), at which stage the cartilaginous anlagen of the humerus, radius and ulna are continuous. Subsequently, longitudinal segmentation produces separation of the distal radius and ulna. However, temporarily, the proximal ends are united and continue to share a common perichondrium. We investigated the hypothesis that posterior congenital dislocation of the radial head and proximal radioulnar fusion are different clinical manifestations of the same primary developmental abnormality. Records were searched for ''proximal radioulnar fusion/posterior radial head dislocation'' in patients followed at the local Children's Hospital and Rehabilitation Centre for Children. Relevant radiographic, demographic and clinical data were recorded. Ethics approval was obtained through the University Research Ethics Board. In total, 28 patients met the inclusion criteria. The majority of patients (16) had bilateral involvement; eight with posterior dislocation of the radial head only; five had posterior radial head dislocation with radioulnar fusion and two had radioulnar fusion without dislocation. One patient had bilateral proximal radioulnar fusion and posterior dislocation of the left radial head. Nine patients had only left-sided involvement, and three had only right-sided involvement.The degree of proximal fusion varied, with some patients showing 'complete' proximal fusion and others showing fusion that occurred slightly distal to the radial head: 'partially separated.' Associated disorders in our cohort included Poland syndrome (two patients), Cornelia de Lange syndrome, chromosome anomalies (including tetrasomy X) and Cenani Lenz syndactyly. The suggestion of a developmental relationship between posterior dislocation of the radial head and proximal radioulnar fusion is supported by the fact that both anomalies

    Ultraviolet radiation (UV) has the possibility to both harm and to benefit human beings when unprotected exposure occurs. After receiving small amounts of UV our bodies begin to synthesise vitamin D, which is essential for maintaining healthy bones, however excessive UV exposure can result in a variety of damaging outcomes ranging from sunburn to skin cancer and cataracts. For this reason it is very important to understand the different environments in which people encounter UV so as to better prepare the public to make smart and healthy sun exposure decisions. Each day more and more people are moving into large cities around the world and spending their time inside the urban canyon, however UV measurements are generally taken at scientific stations in open areas or on top of tall buildings, meaning that at times the environmental characteristics measured may not accurately represent those found at street-level in these highly urbanized areas. Urban canyons are home to both very tall buildings and tropospheric air pollution, each of which reduces the amount of UV reaching street-level. This study measured the varying difference between UV measurements taken at street-level and at a standard UV monitoring site on top of a building outside of the urban canyon. Investigation was conducted in the central business district (CBD) of Brisbane, Australia, which models the CBDs of large cities around the world in that it boasts a great number of tall buildings, including many skyscrapers. Data was collected under clear sky conditions at five different street-level sites in the CBD (on either side of two streets running perpendicular to one another (four sites) and in a public square) and then compared to that obtained on the same day at the Queensland University of Technology's Australian Sun and Health Research Laboratory (ASHRL), which is located 2.5 kilometres outside Brisbane's CBD. Minimum erythemal dose (MED) data was collected at each location and it was found that

    The Queensland University of Technology (QUT) Drop Tower Facility is a {raise.17exscriptstyle˜}2.1 second, 21.3 m fall, dual capsule drop tower system. The dual capsule comprises of an uncoupled exterior hollow drag shield that experiences drag by the ambient atmosphere with the experimental capsule falling within the drag shield. The dual capsule system is lifted to the top of the drop tower via a mechanical crane and the dropping process is initiated by the cutting of a wire coupling the experimental package and suspending the drag shield. The internal experimental capsule reaches the bottom of the drag shield floor just prior to the deceleration stage at the air bag and during this time experience gravity levels of {raise.17exscriptstyle˜}10textsuperscript{-6} g. The deceleration system utilizes an inflatable airbag where experimental packages can be designed to experience a maximum deceleration of {raise.17exscriptstyle˜}10textsuperscript{18} g for {raise.17exscriptstyle˜}0.1 seconds. The drag shield can house experimental packages with a maximum diameter of 0.8 m and height of 0.9 m. The drag shield can also be used in foam mode, where the walls are lined with foam and small experiments can be dropped completely untethered. This mode is generally used for the study of microsatellite manipulation. Payloads can be powered by on-board power systems with power delivered to the experiment until free fall occurs. Experimental data that can be collected includes but is not limited to video, temperature, pressure, voltage/current from the power supply, and triggering mechanisms outputs which are simultaneously collected via data logging systems and high speed video recording systems. Academic and commercial projects are currently under investigation at the QUT Drop Tower Facility and collaboration is openly welcome at this facility. Current research includes the study of heterogeneously burning metals in oxygen which is aimed at fire safety applications and

    Full Text Available A new species of the genus Tasmanitachoides Erwin from North Queensland is described: T. glabellus n. sp. The species belongs to the T. murrumbidgensis¿group of species that is characterized by its distinctly impressed clypeus, but it is distinguished from all related species by its glabrous body surface. It is the first Tasmanitachoides from northern Australia to be found in rainforest on high mountains and has thus probably preserved the original habits of the genus that are still characteristic for those species living in southern temperate regions of Australia. Tasmanitachoides lutus (Darlington so far known from the type locality in southern New South Wales and from the holotype only, is now recorded from eastern Victoria.

    Issue addressed Alcohol-related road crashes are a leading cause of the injury burden experienced by Indigenous Australians. Existing drink driving programs are primarily designed for the mainstream population. The 'Hero to Healing' program was specifically developed with Indigenous communities and is underpinned by the Community Reinforcement Approach (CRA). This paper reports on the formative evaluation of the program from delivery in two Far North Queensland communities. Methods Focus groups and semistructured interviews were conducted with drink driver participants (n=17) and other Elders and community members (n=8) after each program. Qualitative content analysis was used to categorise the transcripts. Results The CRA appealed to participants because of its flexible nature and encouragement of rearranging lifestyle factors, without specific focus on alcohol use. Participants readily identified with the social and peer-related risk and protective factors discussed. Cofacilitation of the program with Elders was identified as a key aspect of the program. More in-depth discussion about cannabis and driving, anger management skills and relationship issues are recommended. Conclusions Participants' recognition of content reinforced earlier project results, particularly the use of kinship pressure to motivate younger family members to drink drive. Study findings suggest that the principles of the CRA are useful; however, some amendments to the CRA components and program content were necessary. So what? Treating drink driving in regional and remote Indigenous Australian communities as a community and social issue, rather than an individual phenomenon, is likely to lead to a reduction in the number of road-related injuries Indigenous people experience.

    Little is reported about the nutrition-related needs and preferences of women seeking maternity services, particularly Maori and Pasifika (M&P) women who have higher chronic disease rates in Queensland. Nutrition-related knowledge, needs, behaviours and education preferences were compared between women of M&P ancestry and non-Maori and Pasifika women (NMP). Women (≥18 years) admitted to the postnatal ward were surveyed. Anthropometry, dietary quality, nutrition education preferences, country of birth and ancestry were collected. Analysis included chi-squared and t-tests. The survey was completed by 399 eligible women. Country of birth data suggested 4% of respondents were Pasifika and failed to separately identify New Zealand Maori, whereas 18% of respondents (n=73) reported M&P ancestry. Descriptors were similar between groups (28±5 years; 91% any breastfeeding; 18% gestational diabetes mellitus; p>0.05). However M&P women were less often university educated (M&P:6(9%); NMP:71(22%), p2 children (M&P: 30(54%); NMP:70(30%), pwomen reported heavier weight at conception (M&P:79.0±20.2kg, 29.2±7.5kg/m 2 ; NMP:71.3±18.9kg, 26.3±6.5kg/m 2 , p75%) women did not know their recommended weight gain. Many respondents reported inadequate intake of vegetables (95%), fruit (29%) and dairy (69%) during pregnancy. Two-fifths (38-41%) reported interest in perinatal nutrition education, with topics including healthy eating postpartum. Findings enable targeted service delivery according to women's preferences. Collecting ancestral and maternal data to facilitate the provision of appropriate nutrition education may be critical for achieving optimal maternal outcomes in Maori and Pasifika women.

    2012-10-01

    A deep crustal seismic reflection and magnetotelluric survey, conducted in 2007, established the architecture and geodynamic framework of north Queensland, Australia. Results based on the interpretation of the deep seismic data include the discovery of a major, west-dipping, Paleoproterozoic (or older) crustal boundary, considered to be an ancient suture zone, separating relatively nonreflective, thick crust of the Mount Isa Province from thinner, two layered crust to the east. Farther to the east, a second major crustal boundary also dips west or southwest, offsetting the Moho and extending below it, and is interpreted as a fossil subduction zone. Across the region, the lower crust is mostly highly reflective and is subdivided into three mappable seismic provinces, but they have not been tracked to the surface. In the east, the Greenvale and Charters Towers Provinces, part of the Thomson Orogen, have been mapped on the surface as two discrete provinces, but the seismic interpretation raises the possibility that these two provinces are continuous in the subsurface, and also extend northwards to beneath the Hodgkinson Province, originally forming part of an extensive Neoproterozoic-Cambrian passive margin. Continuation of the Thomson Orogen at depth beneath the Hodgkinson and Broken River Provinces suggests that these provinces (which formed in an oceanic environment, possibly as an accretionary wedge at a convergent margin) have been thrust westwards onto the older continental passive margin. The Tasman Line, originally defined to represent the eastern limit of Precambrian rocks in Australia, has a complicated geometry in three dimensions, which is related to regional deformational events during the Paleozoic. Overall, the seismic data show evidence for a continental margin with a long history (Paleoproterozoic to early Mesozoic) but showing only limited outward growth by crustal accretion, because of a repeated history of overthrust shortening during repeated

    2015-01-01

    Full Text Available In-water monitoring of marine vertebrates is usually expensive while the use of stranding data can be used to provide a cost-effective estimation of disease and mortality. Strandings for Queensland are recorded in a web based database (StrandNet managed by the Queensland Government’s Department of Environment and Heritage Protection (EHP. Data recorded in StrandNet from the east coast of Queensland between 1996 and 2013 were investigated for patterns of stranding. Significant trends in Queensland over this time were (i an increase in the number of animals reported stranded within this study site; (ii a species (loggerhead and green marine turtles prevalence; (iii a seasonal effect on different age classes stranding with most overall strandings occurring between August and November; and (iv stranding hotspots (Moreton Bay, Hervey Bay, Rockhampton region, and Cleveland Bays persisting throughout the study timeframe. This study suggested that intervention strategies, such as rehabilitation, should be able to be focussed on periods of heightened importance and specific localities to minimize health risks and contribute to sustainable use of resources.

    Conclusions: In this endemic region of north Queensland, exposure to wildlife and seasonal rainfall may be substantial exposure factors for the development of Q fever. The region studied is a popular tourist destination. An understanding of risk factors involved can help practitioners who see residents or returned travelers from the region, with an undifferentiated fever.

    Farmers constitute an occupation group at a heightened suicide risk compared to the general population. To date, research has tried to explain this peculiarity by identifying suicide risk factors that are common to the whole of the farming population. There are, however, indications that risk factors may be different for different sub-populations of farmers, such as younger/older farmers or farm managers/farm labourers. This study compared the characteristics of suicides by farm managers and farm labourers, while controlling for the effect of age. A review of two datasets, the Queensland Suicide Register and the National Coroners Information System, was conducted in which a total of 78 cases of farm managers and 69 cases of farm labourers were identified as a suicide during 2000-2009, Queensland, Australia. The main outcome measures included various demographic characteristics, circumstances related to death, health and mental health variables, and history of stressful life events. The two groups differed in marital status, living arrangements, ethnicity, physical and mental illness, alcohol and drug abuse, contact with a health professional prior to death, and specific life events such as relationship breakdown and recent/pending unemployment. The majority of these differences were not statistically significant once age was accounted for. However, differences in psychiatric variables and experience of a recent/pending unemployment remained significant. This study contributes towards better understanding of suicide among farmers in different job positions, and highlights the need for tailored suicide prevention initiatives that consider a combination of age- and job-specific suicide risk and protective factors among farmers.

    2006-02-01

    Reproductive success of male insects commonly hinges both on their ability to secure copulations with many mates and also on their ability to inseminate and inhibit subsequent sexual receptivity of their mates to rival males. We here present the first investigation of sperm storage in Queensland fruit flies (Tephritidae: Bactrocera tryoni; a.k.a. 'Q-flies') and address the question of whether remating inhibition in females is directly influenced by or correlated with number of sperm stored from their first mates. We used irradiation to disrupt spermatogenesis and thereby experimentally reduce the number of sperm stored by some male's mates while leaving other aspects of male sexual performance (mating probability, latency until copulating, copula duration) unaffected. Females that mated with irradiated rather than normal males were less likely to store any sperm at all (50% vs. 89%) and, if some sperm were stored, the number was greatly reduced (median 11 vs. 120). Despite the considerable differences in sperm storage, females mated by normal males and irradiated males were similarly likely to remate at the next opportunity, indicating (1) number of sperm stored does not directly drive female remating inhibition and (2) factors actually responsible for remating inhibition are similarly expressed in normal and irradiated males. While overall levels of remating were similar for mates of normal and irradiated males, factors responsible for female remating inhibition were positively associated with presence and number of sperm stored by mates of normal but not irradiated males. We suggest seminal fluids as the most likely factor responsible for remating inhibition in female Q-flies, as these are likely to be transported in proportion to number of sperm in normal males, be uninfluenced by irradiation, and be transported without systematic relation to sperm number in irradiated males.

    Parthenium weed is a highly invasive alien species in more than 40 countries around the world. Along with severe negative effects on human and animal health and crop production, it also causes harm to ecosystem functioning by reducing the native plant species biodiversity. However, its impacts on native plant species, especially in pasture communities, are less known. Given parthenium weed causes substantial losses to Australian pastures' productivity, it is crucial to estimate its impact on pasture communities. This study evaluates the impact of parthenium weed upon species diversity in a pasture community at Kilcoy, south east Queensland, Australia. Sub-sites containing three levels of parthenium weed density (i.e. high, low and zero) were chosen to quantify the above- and below-ground plant community structure. Species richness, diversity and evenness were all found to be significantly reduced as the density of parthenium weed increased; an effect was evident even when parthenium weed was present at relatively low densities (i.e. two plants m -2 ). This trend was observed in the summer season as well as in winter season when this annual weed was absent from the above-ground plant community. This demonstrates the strong impact that parthenium weed has upon the community composition and functioning throughout the year. It also shows the long-term impact of parthenium weed on the soil seed bank where it had displaced several native species. So, management options used for parthenium weed should also consider the reduction of parthenium weed seed bank along with controlling its above-ground populations.

  8. Proximal and distal muscle fatigue differentially affect movement coordination.

    Directory of Open Access Journals (Sweden)

    Jeffrey C Cowley

    Full Text Available Muscle fatigue can cause people to change their movement patterns and these changes could contribute to acute or overuse injuries. However, these effects depend on which muscles are fatigued. The purpose of this study was to determine the differential effects of proximal and distal upper extremity muscle fatigue on repetitive movements. Fourteen subjects completed a repetitive ratcheting task before and after a fatigue protocol on separate days. The fatigue protocol either fatigued the proximal (shoulder flexor or distal (finger flexor muscles. Pre/Post changes in trunk, shoulder, elbow, and wrist kinematics were compared to determine how proximal and distal fatigue affected multi-joint movement patterns and variability. Proximal fatigue caused a significant increase (7°, p < 0.005 in trunk lean and velocity, reduced humeral elevation (11°, p < 0.005, and increased elbow flexion (4°, p < 0.01. In contrast, distal fatigue caused small but significant changes in trunk angles (2°, p < 0.05, increased velocity of wrench movement relative to the hand (17°/s, p < 0.001, and earlier wrist extension (4%, p < 0.005. Movement variability increased at proximal joints but not distal joints after both fatigue protocols (p < 0.05. Varying movements at proximal joints may help people adapt to fatigue at either proximal or distal joints. The identified differences between proximal and distal muscle fatigue adaptations could facilitate risk assessment of occupational tasks.

    Ruizenaar, M. G. A.

    1989-04-01

    SINA, a signal generator that can be used for testing proximity fuses, is described. The circuitry of proximity fuses is presented; the output signal of the RF circuit results from a mixing of the emitted signal and received signal that is Doppler shifted in frequency by the relative motion of the fuse with respect to the reflecting target of surface. With SINA, digitized and stored target and clutter signals (previously measured) can be transformed to Doppler signals, for example during a real flight. SINA can be used for testing fuse circuitry, for example in the verification of results of computer simulations of the low frequency Doppler signal processing. The software of SINA and its use are explained.

    Full Text Available Notwithstanding the recent success in major limb replantation achieved through the advancements in microsurgical techniques, the viability of the extremity is still relatively low at the transhumeral level following a replantation. There are no exact guidelines for deciding whether to undertake a stump repair or a replantation in such amputations at the proximal level. However, a highly motivated patient with realistic expectations and protected shoulder function can be a candidate to undergo replantation. The replanted arm may help the uninjured arm in daily activities. In this report we present the case of a 47-year-old man whose arm was amputated at proximal third level by an asphalt machine and successfully replanted together with the encountered problems and their solutions. The roadmap followed in this rare case may be a guide for hand surgeons.

    The authors' objective was to determine whether residential proximity to an industrial park (IP) is associated with increased perinatal mortality (PM). This semiecological study included 63,850 delivered births with 840 cases of PM (1995-2000). The authors categorized the study populations by ethnicity (ie, Bedouin and Jewish) and type of locality. Residential distance from the IP served as a surrogate indicator of exposure. Among Bedouin newborns, proximity to the IP was associated with increased PM rates (relative risk = 1.45; 95% confidence interval = 1.22-1.72). The excess in PM was not related to maternal or newborn physical characteristics that the authors observed. The risk of PM and its components in the Jewish localities was not associated with IP proximity. The association between residential proximity to the IP and excess in PM among only Bedouin newborns may be related to vulnerability caused by the nomadic nature of the society.

    This paper demonstrates how macroeconomic indicators of sustainable development can be applied to the Queensland economy. We derive a Genuine Savings Rate (GSR) for Queensland for the period 1989 to 1999, which is then compared with the World Bank estimate of Australia's GSR for the same period. Specifically, we examine how well a single "headline" indicator based on the World Bank's GSR performs as a measure of overall sustainability. In doing so, we review criticisms of the GSR and compare ...

Significant complications were perforation of the articular surface through bolts or blades (n = 8), implant-related pain (n = 10), fragment dislocation (n = 2), nonunion (n = 2), humeral head necrosis (n = 3), and superficial infection (n = 1). 1 year after the operation, the Constant-Murley Score showed a median value of 75.3 in the injured shoulder and of 89.9 in the uninjured shoulder. The DASH (Disability of the Arm, Shoulder and Hand) Score was 5.9 preoperatively and 9.3 at 1 year postoperatively. The worst results regarding the Constant-Murley Score as well as the DASH Score were found in C-type fractures.

  15. An historical perspective on early progress of Queensland water fluoridation 1945-1954: sheep, climate and sugar.

    2004-06-01

    Queensland's virtual rejection of artificial water fluoridation sets it apart from other Australian states, yet the early fluoride environs has been scantily recorded. This paper used archives, literature review, personal interview and the traditional historic method. The connection between Queensland artesian bore water and caries resistance was postulated as early as 1912. Four decades later, two Queensland-specific factors influenced the planning to fluoridate community water supplies. The first (1945-1950) was confusion between the high levels of fluoride in artesian water supplying the pastoral industry and the scientific concept of artificial water fluoridation of communal supplies. The second (1952-1954) involved further scientific investigation involving water consumption patterns, occupational dehydration and fluid homeostasis within a sub-tropical climate. The role of the Australian Dental Association Queensland Branch (ADAQ) in early fluoride politics was minimal. Four early protagonists are identified--two dentists, an engineer and the sugar industry. Queensland had its advocates for artificial water fluoridation of communal supply as a means of caries prevention. Interest came from the dental, medical and engineering professions, and from the sugar industry. However, these efforts met with indifference based on confused extrapolation of the artesian experience (1945-1952) and hesitancy (1952-1954) due to contemporaneous concerns about human fluid homeostasis in Queensland's sub-tropical climate.

    Ross River virus (RRV) infection is a debilitating disease that has a significant impact on population health, economic productivity, and tourism in Australia. This study examined epidemiologic patterns of RRV disease in Queensland, Australia, during January 2001-December 2011 at a statistical local area level. Spatio-temporal analyses were used to identify the patterns of the disease distribution over time stratified by age, sex, and space. The results show that the mean annual incidence was 54 per 100,000 persons, with a male:female ratio of 1:1.1. Two space-time clusters were identified: the areas adjacent to Townsville, on the eastern coast of Queensland, and the southeast areas. Thus, although public health intervention should be considered across all areas in which RRV occurs, it should specifically focus on high-risk regions, particularly during summer and autumn to reduce the social and economic impacts of RRV infection. © The American Society of Tropical Medicine and Hygiene.

  18. 'Filthy vessels': milk safety and attempts to restrict the spread of bovine tuberculosis in Queensland.

    2010-01-01

    Bovine tuberculosis is a dangerous mycobacterium that can be conveyed to humans in the meat and milk of cattle. By the mid-1800s, when health scientists began arguing about its zoonotic potential and danger to humans, the disease was well established in Australian cattle herds. This article examines the Queensland response to bovine tuberculosis from the late 1800s to the 1940s, when the problem of tubercular cattle could no longer be ignored. It shows that despite widespread concern about milk safety and increasing knowledge of the disease's aetiology, the Queensland government directed its milk safety activities towards public health education rather than the inadequacies of the dairy industry's approach to bovine tuberculosis. As such, it was tardy in addressing bovine tuberculosis.

    It remains unclear over whether it is possible to develop an epidemic forecasting model for transmission of dengue fever in Queensland, Australia. To examine the potential impact of El Niño/Southern Oscillation on the transmission of dengue fever in Queensland, Australia and explore the possibility of developing a forecast model of dengue fever. Data on the Southern Oscillation Index (SOI), an indicator of El Niño/Southern Oscillation activity, were obtained from the Australian Bureau of Meteorology. Numbers of dengue fever cases notified and the numbers of postcode areas with dengue fever cases between January 1993 and December 2005 were obtained from the Queensland Health and relevant population data were obtained from the Australia Bureau of Statistics. A multivariate Seasonal Auto-regressive Integrated Moving Average model was developed and validated by dividing the data file into two datasets: the data from January 1993 to December 2003 were used to construct a model and those from January 2004 to December 2005 were used to validate it. A decrease in the average SOI (ie, warmer conditions) during the preceding 3-12 months was significantly associated with an increase in the monthly numbers of postcode areas with dengue fever cases (beta=-0.038; p = 0.019). Predicted values from the Seasonal Auto-regressive Integrated Moving Average model were consistent with the observed values in the validation dataset (root-mean-square percentage error: 1.93%). Climate variability is directly and/or indirectly associated with dengue transmission and the development of an SOI-based epidemic forecasting system is possible for dengue fever in Queensland, Australia.

    Queensland fruit fly (Bactrocera tryoni) is a major orchard pest in Australia. Adult flies lay their eggs into ripe fruit, resulting in larval infestation and the spread of bacterial and fungal rots. The role of these microbes in fruit fly ecology is only now being elucidated, with much of the emphasis to date focusing on bacterial communities. In our study, we explored the diversity of yeast species associated with B. tryoni adults and larvae. We found larvae were highly assoc...

    Full Text Available Frontier violence is now an accepted chapter of Australian history.  Indigenous resistance is central to this story, yet little examined as a military phenomenon (Connor 2004.  Indigenous military tactics and objectives are more often assumed than analysed. Building on Laurie’s and Cilento’s contentions (1959 that an alliance of Aboriginal groups staged a ‘Black War’ across southern Queensland between the 1840s and 1860s, the author seeks evidence for a historically definable conflict during this period, complete with a declaration, coordination, leadership, planning and a broader objective: usurping the pastoral industry.   As the Australian situation continues to present elements which have proved difficult to reconcile with existing paradigms for military history, this study applies definitions from guerilla and terrorist conflict (e.g. Eckley 2001, Kilcullen 2009 to explain key features of the southern Queensland “Black War.” The author concludes that Indigenous resistance, to judge from southern Queensland, followed its own distinctive pattern.  It achieved coordinated response through inter-tribal gatherings and sophisticated signaling.  It relied on economic sabotage, targeted payback killings and harassment.  It was guided by reticent “loner-leaders.” Contrary to the claims of military historians such as Dennis (1995, the author finds evidence for tactical innovation.  He notes a move away from pitched battles to ambush affrays; the development of full-time ‘guerilla bands’; and use of new materials.

    2013-08-01

    To identify the perceived barriers to Hendra virus (HeV) management by private equine veterinarians in Queensland. An exploratory qualitative study of private equine veterinarians registered and working in coastal Queensland. A questionnaire that included eight open-ended questions about the management of HeV was used in face-to-face in-depth interviews with 21 veterinary personnel working in equine or mixed private practice between Far North and South-East Queensland in 2009-10. The qualitative data was entered and analysed thematically using QSR's International's Nvivo 9 qualitative data analysis software. This study revealed key issues associated with HeV testing: (1) inadequate knowledge of testing procedures and laboratory diagnostic pathways; (2) difficulty in accessing laboratory services; (3) responsibility for cost of collection and transport of specimen; and (4) the role of government. Participants perceived these issues as reducing potential HeV case management efficiency. Although HeV management plans have been modified in part since 2009-10, this study highlights the importance of considering the perspectives of private veterinary practitioners in any biosecurity protocols. © 2013 Australian Veterinary Association.

    Full Text Available Tobacco smoking is a major health issue for Indigenous Australians, however there are few interventions with demonstrated efficacy in this population. The Transtheoretical Model may provide a useful framework for describing smoking behaviour and assessing readiness to quit, with the aim of developing better interventions. Interviews were conducted with 593 Indigenous Australians in eight rural and remote communities in north Queensland, to examine stages of change and smoking behaviour. Among current smokers, 39.6% and 43.4% were in Precontemplation and Contemplation stages respectively. A further 13.9% were making preparations to quit (Preparation whilst only 3.2% said they were actively trying to quit (Action. When analysed by stage of change, the pattern of smoking-related behaviours conformed to the results of past research using the model. Importantly however, distribution of individuals across the stages opposes those observed in investigations of smoking behaviour in non-Indigenous Australian populations. The Transtheoretical Model can be used to meaningfully classify Indigenous smokers in remote north Queensland according to stages along the behaviour change continuum. Importantly, in this large sample across eight communities, most Indigenous smokers were not making preparations to change their smoking behaviour. This suggests that interventions should focus on promoting movement toward the Preparation and Action stages of change.

    Quad bike safety represents the quintessential wicked problem. To address this wicked problem, this research explores the use of quad bikes in the northwestern region of outback Queensland, Australia, concentrating efforts on the pastoral industry. Focus groups and interviews were conducted with pastoralists, farmers, retailers, repairers, healthcare professionals, and regulators. The discussions revealed the diverse activities currently undertaken in the region's pastoral enterprises while riding a quad bike, and that attitudes toward the purchase and use of quad bikes vary and may be influenced by retailers. Perceptions of risk and safety in the use of quad bikes in occupational settings also varied. The findings from this study provide insight into the decisions of local pastoralists and agriculturalists to use quad bikes in their workplaces, and attitudes toward safety and injury prevention relating to quad bike use in these industries in northwestern outback Queensland. This study is the first step toward understanding quad bike use in this region, with the goal of reducing injury and death, and will be used in policy and legislation development regarding the use and safety of quad bikes in Australia.

    Leptospirosis is an emerging infectious disease, with increasing frequency and severity of outbreaks, changing epidemiology of populations at risk, and the emergence of new serovars. Environmental drivers of disease transmission include flooding, urbanisation, poor sanitation, changes in land use and agricultural practices, and socioeconomic factors. In Queensland, human infection with Leptosira borgpetersenii serovar Arborea was first reported in 2001. This study aims to report the emergence of serovar Arborea in Queensland from 2001 to 2013, and investigate potential risk factors for infection and drivers of emergence. Data on laboratory-confirmed cases of human leptospirosis in Queensland were obtained from the enhanced surveillance system at the WHO/FAO/OIE Collaborating Centre for Reference and Research on Leptospirosis in Brisbane, Australia. The changing epidemiology of serovar Arborea from 2001 to 2003 was described with respect to case numbers, proportion of leptospirosis cases attributed to the serovar, and geographic distribution. Differences in risk factors for the most common serovars were compared. During this period, 1289 cases of leptospirosis were reported, including 233 cases attributed to serovar Arborea. Risk factors for infection include male gender (91 % of cases), occupation, and recreational exposure. Most common occupations recorded were banana workers (28.4 %), meat workers (7.2 %), dairy farmers (5.8 %), graziers/stockmen (5.5 %), 'other agricultural/rural workers' (16.4 %), and tourists or tourism operators (4.6 %). Time trend analysis showed that while non-Arborea cases decreased over the study period, Arborea cases increased by 3.4 cases per year. The proportion of annual cases attributed to Arborea peaked at 49 % in 2011 after unprecedented flooding in Queensland. Mapping of cases by residential location showed expansion of the geographic range of serovar Arborea, concentrating mostly around Brisbane, Cairns and Innisfail. Serovars

    Features of the land management history over a 125,755 km(2) area of central Queensland, Australia were determined from a variety of sources. A random sample of 205 site locations provided the basis for determining trends in land use. Trends in vegetation clearing were determined using sequential aerial photography for the sample sites, revealing a steady rate averaging nearly 1% of the region per annum over 41 years. This measure of sustained clearing over a large region is higher than recently published clearing rates from South America. Land types have been selectively cleared with over 90% of the Acacia on clay land type having been cleared. A land-holder questionnaire pertaining to the random sites yielded a response rate of 71% and provided information on vegetation clearing, ploughing, tree killing (ring-barking or tree poisoning), and fire frequency, season and intensity. The land-holder responses were compared with independent data sources where possible and revealed no mis-information. However, land-holders may have been marginally less likely to respond if the sample area had been cleared, although this effect was not statistically significant. Ploughing and tree killing are variable depending on land type, but the former has affected about 40% of the Acacia on clay land type, effectively eliminating options for natural regrowth. The proportion of decade-site combinations that were reported as having no fires increased from 22% in the 1950s to an average of 42% for subsequent decades, although the reporting of more than one fire per decade has been relatively constant through the study period. The reporting of at least one fire per decade varies from 46% for the Acacia on sand land type to 77% for the Eucalypt on sand land type for decade-site combinations. Fires are more intense when associated with clearing than in uncleared vegetation, but the proportion of cool and hot fires is relatively constant between land types in uncleared vegetation. Nearly

    Full Text Available Worldwide, more than 40% of the population is at risk from dengue and recent estimates suggest that up to 390 million dengue infections are acquired every year. The Eliminate Dengue (ED Program is investigating the use of Wolbachia-infected, transmission-compromised, mosquitoes to reduce dengue transmission. Previous introductions of genetically-modified strategies for dengue vector control have generated controversy internationally by inadequately engaging host communities. Community Engagement (CE was a key component of the ED Program's initial open release trials in Queensland Australia. Their approach to CE was perceived as effective by the ED team's senior leadership, members of its CE team, and by its funders, but if and why this was the case was unclear. We conducted a qualitative case study of the ED Program's approach to CE to identify and critically examine its components, and to explain whether and how these efforts contributed to the support received by stakeholders.In-depth semi-structured interviews were conducted with 24 participants with a range of experiences and perspectives related to the ED Program's CE activities. Our analytic approach combined techniques of grounded theory and qualitative description. The ED Program's approach to CE reflected four foundational features: 1 enabling conditions; 2 leadership; 3 core commitments and guiding values; and 4 formative social science research. These foundations informed five key operational practices: 1 building the CE team; 2 integrating CE into management practices; 3 discerning the community of stakeholders; 4 establishing and maintaining a presence in the community; and 5 socializing the technology and research strategy. We also demonstrate how these practices contributed to stakeholders' willingness to support the trials.Our case study has identified, and explained the functional relationships among, the critical features of the ED Program's approach to CE.

    2016-01-01

    This book introduces computational proximity (CP) as an algorithmic approach to finding nonempty sets of points that are either close to each other or far apart. Typically in computational proximity, the book starts with some form of proximity space (topological space equipped with a proximity relation) that has an inherent geometry. In CP, two types of near sets are considered, namely, spatially near sets and descriptivelynear sets. It is shown that connectedness, boundedness, mesh nerves, convexity, shapes and shape theory are principal topics in the study of nearness and separation of physical aswell as abstract sets. CP has a hefty visual content. Applications of CP in computer vision, multimedia, brain activity, biology, social networks, and cosmology are included. The book has been derived from the lectures of the author in a graduate course on the topology of digital images taught over the past several years. Many of the students have provided important insights and valuable suggestions. The topics in ...

    Identification of molecular interactions is paramount to understanding how cells function. Most available technologies rely on co-purification of a protein of interest and its binding partners. Therefore, they are limited in their ability to detect low-affinity interactions and cannot be applied to proteins that localize to difficult-to-solubilize cellular compartments. In vivo proximity labeling (IPL) overcomes these obstacles by covalently tagging proteins and RNAs based on their proximity in vivo to a protein of interest. In IPL, a heterobifunctional probe comprising a photoactivatable moiety and biotin is recruited by a monomeric streptavidin tag fused to a protein of interest. Following UV irradiation, candidate interacting proteins and RNAs are covalently biotinylated with tight spatial and temporal control and subsequently recovered using biotin as an affinity handle. Here, we describe experimental protocols to discover novel protein-protein and protein-RNA interactions using IPL. © 2017 by John Wiley & Sons, Inc. Copyright © 2017 John Wiley & Sons, Inc.

    Despite over-representation of Indigenous Australians in sentinel studies of injecting drug use, little is known about relevant patterns of drug use and dependence. This study compares drug dependence and possible contributing factors in Indigenous and non-Indigenous Australians who inject drugs. Respondent-driven sampling was used in major cities and 'peer recruitment' in regional towns of Queensland to obtain a community sample of Indigenous (n = 282) and non-Indigenous (n = 267) injectors. Data are cross sectional. Multinomial models were developed for each group to examine types of dependence on injected drugs (no dependence, methamphetamine-dependent only, opioid-dependent only, dependent on methamphetamine and opioids). Around one-fifth of Indigenous and non-Indigenous injectors were dependent on both methamphetamine and opioids in the previous 12 months. Psychological distress was associated with dual dependence on these drugs for Indigenous [adjusted relative risk (ARR) 4.86, 95% confidence interval (CI) 2.08-11.34] and non-Indigenous (ARR 4.14, 95% CI 1.59-10.78) participants. Unemployment (ARR 8.98, 95% CI 2.25-35.82) and repeated (> once) incarceration as an adult (ARR 3.78, 95% CI 1.43-9.97) were associated with dual dependence for Indigenous participants only. Indigenous participants had high rates of alcohol dependence, except for those dependent on opioids only. The drug dependence patterns of Indigenous and non-Indigenous people who inject drugs were similar, including the proportions dependent on both methamphetamine and opioids. However, for Indigenous injectors, there was a stronger association between drug dependence and contextual factors such as unemployment and incarceration. Expansion of treatment options and community-level programs may be required. [Smirnov A, Kemp R, Ward J, Henderson S, Williams S, Dev A, Najman J M.

    Ediea homevalensis H. Nishida, Kudo, Pigg & Rigby gen. et sp. nov. is proposed for permineralized pollen-bearing structures from the Late Permian Homevale Station locality of the Bowen Basin, Queensland, Australia. The taxon represents unisexual fertile shoots bearing helically arranged leaves on a central axis. The more apical leaves are fertile microsporophylls bearing a pair of multi-branched stalks on their adaxial surfaces that each supports a cluster of terminally borne pollen sacs. Proximal to the fertile leaves there are several rows of sterile scale-like leaves. The pollen sacs (microsporangia) have thickened and dark, striate walls that are typical of the Arberiella type found in most pollen organs presumed to be of glossopterid affinity. An examination of pollen organs at several developmental stages, including those containing in situ pollen of the Protohaploxypinus type, provides the basis for a detailed analysis of these types of structures, which bear similarities to both compression/impression Eretmonia-type glossopterid microsporangiate organs and permineralized Eretmonia macloughlinii from Antarctica. These fossils demonstrate that at least some Late Permian pollen organs were simple microsporophyll-bearing shoot systems and not borne directly on Glossopteris leaves.

    Little is known about the travel health advice obtained by tourists travelling to Magnetic Island, which is a known risk area for the potentially fatal 'Irukandji' jellyfish on the Great Barrier Reef coast of north Queensland, Australia. Structured interviews were conducted with 208 ferry passengers (93% response) travelling between Townsville (Latitude 19 degrees S) and Magnetic Island. Less than half of the international tourists (21, 46%) had obtained travel health advice before coming to north Queensland, although they were significantly more likely to have done so than domestic tourists (pjellyfish was (pjellyfish. Most of the international tourists travelled to north Queensland by bus (30, 65%), while most domestic tourists arrived by private car (12, 40%) or plane (10, 33%). Only a small proportion of international tourists knew about Irukandji jellyfish and most tourists had not received travel health advice. The majority of tourists had not received further information about Irukandji jellyfish risk whilst on the island. All travellers to popular north Queensland tourist areas need travel health advice, which includes advice on avoiding contact with Irukandji and Chironex box jellyfish. Health promotion campaigns directed at providing this advice need to be aware that most tourists to north Queensland arrive by bus or car and the only 'shared' vehicle, at least to Magnetic Island, is the passenger ferry.

  3. Topology of digital images visual pattern discovery in proximity spaces

    Peters, James F

    2014-01-01

    This book carries forward recent work on visual patterns and structures in digital images and introduces a near set-based a topology of digital images. Visual patterns arise naturally in digital images viewed as sets of non-abstract points endowed with some form of proximity (nearness) relation. Proximity relations make it possible to construct uniform topolo- gies on the sets of points that constitute a digital image. In keeping with an interest in gaining an understanding of digital images themselves as a rich source of patterns, this book introduces the basics of digital images from a computer vision perspective. In parallel with a computer vision perspective on digital images, this book also introduces the basics of prox- imity spaces. Not only the traditional view of spatial proximity relations but also the more recent descriptive proximity relations are considered. The beauty of the descriptive proximity approach is that it is possible to discover visual set patterns among sets that are non-overlapping ...

    Despite evidence that outcomes are highly valued when they are expected sooner rather than further into the future (Ainslie, 1975), limited research effort has been devoted to understanding the role of exercise outcome proximity. The purpose of this study was to examine how temporal proximity to positive outcomes influences exercisers' intrinsic motivation. We expected that focusing people on temporally proximal exercise outcomes would increase intrinsic motivation, especially among low-frequency exercisers. This online experimental study was completed by 135 community exercisers (Mage  = 31.11, SD = 10.29; 62% female) who reported an average of 4.86 exercise bouts per week (SD = 2.12). Participants were randomly assigned to a condition that primed temporally proximal positive exercise outcomes (i.e. experienced during or directly following an exercise bout) or temporally distal outcomes (i.e. experienced after days, months, or years of regular exercise). Participants then reported perceptions of behavioral regulation in exercise. As expected, the proximal exercise outcome condition elicited increased intrinsic regulation among those participants who exercised less frequently (i.e. 1 SD below the mean). This study reveals the importance of considering proximity as an important dimension of exercise outcomes-particularly when promoting intrinsic motivation among relatively infrequent exercisers. © 2014 The International Association of Applied Psychology.

  5. Lactate oxidation by three segments of the rabbit proximal tubule

    Oxidation of (U/sup 14/C)lactate to /sup 14/CO/sub 2/ was measured in vitro, in nonperfused anatomically defined segments of rabbit proximal tubule (S1, proximal convoluted, and S2 and S3, proximal straight tubules). The rate of lactate oxidation was similar in S2 and S3 segments, and within the range of lactate oxidation rates measured in vivo. In contrast, the oxidation rate of S1 segments was significantly lower than that of S2 or S3. In proximal straight tubules, lactate oxidation was inhibited by incubation at 0/sup 0/C, or by application of 1 mM ouabain. To determine if the rate of transepithelial transport affected the rate of lactate oxidation, lactate oxidation was measured in proximal straight tubules after the lumen had been opened by perfusion with Ringer's containing 10 mM polyethylene glycol. No difference in lactate oxidation rate was observed between tubules with patent lumina and nonperfused tubules. These results suggest that the various segments of the renal proximal tubule have difference metabolic characteristics, and that the rate of substrate oxidation is related to the activity of the Na/sup +/, K/sup +/-ATPase.

  6. Alongshore variability in beach planform, grain-size distribution and foredune height of an embayed beach: Shoalwater Bay, Queensland, Australia

    Headland-bay beaches (HBB) are common beach-types found throughout the coastlines of the world. Morphodynamics of these structurally-controlled beaches are primarily governed by geological inheritance, wave climate, tidal range and grain-size distribution, which ultimately influence sediment transport across the beach-dune system. For embayed beaches, the degree of curvature (i.e., indentation ratio) has significant implications for littoral cell circulation, which mediates both cross-shore and alongshore sediment transport. This study investigated the morphodynamic controls on longshore and cross-shore sediment transport for a macro-tidal, embayed beach in central Queensland, Australia. Freshwater Beach is a 10 km long embayed beach located in the Shoalwater Bay Training Area, ~50 km north of Yeppoon. Freshwater Beach exhibits an asymmetrical planform which is characterized by a curved "shadow zone" (adjacent to the headland), transitioning to a straight tangential segment extending to the north. The beach is subjected to a mean tidal range of 6 m and prevailing onshore-directed winds and swell from the southeast. A total of 12 topographic profiles at ~1 km spacing were taken along the entire length of the beach to characterize variation in beach slope and foredune height. Sediment samples were collected across each transect for detailed grain-size and geochemical (XRD/XRF and SEM) analysis. Additionally, ground-based LiDAR surveys were conducted along the topographic profiles and for comparison with aerial-based LiDAR surveys. Preliminary results from topographic profiles show that the largest foredunes are located in the central portion of the beach, contrary to most embayed beaches where the largest dunes are typically located downdrift of the headland. Along the exposed section, the foredunes become large (~15 m high) and are hypothesized to be supplied by onshore welded bars that act as a sediment source for the foredunes to grow. Presently the alongshore and

    In the spring of 2014, mass mortalities among wild green sea turtles occurred off the coast of south-east Queensland, Australia. The suspected causative agent was Caryospora cheloniae, an eimeriid coccidian implicated in previous epizootics. Necropsies were undertaken on a subset of 11 dead turtles, with subsequent histopathology and molecular analyses. All turtles returned positive PCR results for coccidial infection in various tissues; these included the brain, gastrointestinal tract, lung, kidney and thyroid. Granulomatous encephalitis was consistently observed, as well as enteritis and, less frequently, thyroiditis and nephritis. Sequencing and phylogenetic analyses indicated the presence of two distinct coccidian genotypes, presumably separate species-one associated with the brain, gastrointestinal tract and lung, and the second with the thyroid and kidney. Maximum likelihood and Bayesian inference analyses placed the first genotype closest to the lankesterellid genus Schellackia, rather than in the Eimeriidae, while the second was paraphyletic to the eimeriids. Presence of coccidial stages in extra-intestinal tissues of the primary host raises questions about the potential presence of intermediate or paratenic hosts within the life cycles, as well as their current placement relative to the genus Caryospora. This study represents the first genetic characterization of this emerging disease agent in green sea turtles, an endangered species, and has relevance for life-cycle elucidation and future development of diagnostics.

    Members of the hAT transposable element family are mobile in non-host insect species and have been used as transformation vectors in some of these species. We report that the Queensland fruit fly, Bactrocera tryoni, contains at least two types of insect hAT elements called Homer and a Homer-like element (HLE). The Homer element is 3789 bp in size and contains 12-bp imperfect inverted terminal repeats. The Homer element contains a long open reading frame (ORF) that encodes a putative transposase. Three different copies of this long ORF were recovered from the B. tryoni genome and, upon transcription and translation in an in vitro system, all produced transposase. The HLE is an incomplete element since no 3' inverted terminal repeat (ITR) was found. Homer and the HLE are as related to one another as either is to the other insect hAT elements such as Hermes, hobo, hermit and hopper. The structure and distribution of these two Homer elements is described.

    To assess the population prevalence of property, income and emotional impacts of the 2010-2011 Queensland floods and cyclones. Cross-sectional telephone-based survey using a brief trauma exposure and impact screening instrument, conducted between 11 March and 6 June 2011, of 6104 adults who answered natural disaster and mental health questions. Natural disaster property damage exposure and emotional wellbeing impacts. Two-thirds of respondents (62%) reported being affected by the disasters, with property damage exposure ranging from 37.2% (suburb or local area) to 9.2% (own home, with 2.1% living elsewhere at least temporarily). Income was reduced for 17.0% of respondents and 11.7% of income-producing property owners reported damage to those properties. Trauma impacts ranged from 14.3% of respondents feeling "terrified, helpless or hopeless" to 3.9% thinking they might be "badly injured or die". Up to 5 months after the disasters, 7.1% of respondents were "still distressed" and 8.6% were "worried about how they would manage". Adults of working age and residents of regional and remote areas and of socioeconomically disadvantaged areas were disproportionately likely to report exposure to damage and emotional impacts. Weather-related disasters exact a large toll on the population through property damage and resultant emotional effects. Vulnerable subpopulations are more severely affected. There is a need for realistic, cost-effective and rapid-deployment mass interventions in the event of weather disasters.

    Efforts to increase postnatal support available to women and families are hampered by inadequate referral mechanisms. However, the discharge process in maternity services has received little research attention. To review current discharge practices in Queensland, in order to identify mechanisms to minimise fragmentation in the care of women and families as they transition from hospital-based postnatal care to community-based health and other services. A survey of discharge practices in Queensland hospitals that offer birthing services (N=55) and content analysis of discharge summary forms used by those hospitals. Fifty-two Queensland birthing hospitals participated in the study. Discharge summaries were most commonly sent to General Practitioners (83%), less commonly to Child and Family Health Nurses (CFHNs; 52%) and rarely to other care providers. Discharge summaries were usually disseminated within one week of discharge (87%), but did not capture any information about care provided by domiciliary services. Almost one-fifth (19%) of hospitals did not seek women's consent for the disclosure of their discharge summary and only 10% of hospitals had processes for women to check accuracy. Significant gaps in the content of discharge summaries were identified, particularly in psychosocial and cultural information, and post-discharge advice. The format of discharge summaries diminished their readability. Discharge summaries (format and content) should be consistent, comprehensive and specific to maternity services. Discharge summaries should be generated and disseminated electronically at the time of discharge from the maternity service. Women should review their discharge summaries and direct and consent to its dissemination. Copyright © 2013 Australian College of Midwives. Published by Elsevier Ltd. All rights reserved.

    This study aims to ascertain if differences exist in the perception of the professional practice environment and personal well-being of nurses across different geographical areas in Queensland. This paper was performed on a prospective, self-report cross-sectional on-line survey. The study was conducted among the nurses employed in public and private health care settings: acute hospitals, community health and aged care in Queensland, Australia. Participants of this study were 1608 registered and enrolled nurses and assistants in nursing, current members of the Queensland Nurses Union in 2013 and who provided a workplace postcode. One thousand eight of these participants worked in major cities, while 382 in rural locations and 238 in remote areas. None. Scores of well-being as determined by the following scales: the Depression, Anxiety and Stress Scale, the Professional Quality of Life Scale version 5, the Connor-Davidson Resilience Scale and of the Professional Practice Environment using the Practice Environment Scale - Nursing Work Index Revised. Nurses employed in major cities perceived 'nursing foundations for quality care' more favourably than those from other settings. Remote area nurses had lower levels of secondary traumatic stress than nurses in major cities and rural areas. There was no difference between nurses across their geographical locations for stress, anxiety, depression, compassion satisfaction, burnout, resilience and the four other measures of the Practice Environment Scale. The study findings provide new data suggesting that, with the exception of secondary traumatic stress, the personal well-being of nurses does not differ across geographical settings. Similarly, with the exception of the subscale of 'nursing foundations for quality care' there was no difference in perceptions of the professional practice environment. As secondary traumatic stress is associated with burnout, this finding needs to be investigated further. © 2015 National Rural

    2017-08-01

    Events with overlapping elements can be encoded as two separate representations or linked into an integrated representation, yet we know little about the conditions that promote one form of representation over the other. Here, we tested the hypothesis that the proximity of overlapping events would increase the probability of integration. Participants first established memories for house-object and face-object pairs; half of the pairs were learned 24 hr before an fMRI session, and the other half 30 min before the session. During scanning, participants encoded object-object pairs that overlapped with the initial pairs acquired on the same or prior day. Participants were also scanned as they made inference judgments about the relationships among overlapping pairs learned on the same or different day. Participants were more accurate and faster when inferring relationships among memories learned on the same day relative to those acquired across days, suggesting that temporal proximity promotes integration. Evidence for reactivation of existing memories-as measured by a visual content classifier-was equivalent during encoding of overlapping pairs from the two temporal conditions. In contrast, evidence for integration-as measured by a mnemonic strategy classifier from an independent study [Richter, F. R., Chanales, A. J. H., & Kuhl, B. A. Predicting the integration of overlapping memories by decoding mnemonic processing states during learning. Neuroimage, 124, 323-335, 2016]-was greater for same-day overlapping events, paralleling the behavioral results. During inference itself, activation patterns further differentiated when participants were making inferences about events acquired on the same day versus across days. These findings indicate that temporal proximity of events promotes integration and further influences the neural mechanisms engaged during inference.

    The case history and clinical signs of a fatal self-envenomation event by a brown tree snake, Boiga irregularis, in South-east Queensland, Australia, are presented. Clinical signs began 20 minutes post-envenomation with muscle twitching, ataxia, and heat seeking behavior which progressed to partial paralysis by 6 hours, generalised paralysis and respiratory arrest at 10 hours and cardiac arrest by 12 hours post-envenomation. Clinical signs are suggestive of potent neurotoxicity for B. irregularis to its own venom. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Community-acquired methicillin-resistant Staphylococcus aureus (MRSA) susceptible to gentamicin has been reported in a number of countries in the 1990s. To study the acquisition of gentamicin-sensitive MRSA (GS-MRSA) in southeast Queensland and the relatedness of GS-MRSA to other strains of MRSA, 35 cases of infection due to GS-MRSA from October 1997 through September 1998 were examined retrospectively to determine the mode of acquisition and risk factors for MRSA acquisition.

    1998-08-01

    The Queensland fruit fly, Bactrocera tryoni, like the Mediterranean fruit fly, Ceratitis capitata, has a diploid complement of 12 chromosomes, including five pairs of autosomes and a XX/XY sex chromosome pair. Characteristic features of each chromosome are described. Chromosomal homology between B. tryoni and C. capitata has been determined by comparing chromosome banding pattern and in situ hybridisation of cloned genes to polytene chromosomes. Although the evidence indicates that a number of chromosomal inversions have occurred since the separation of the two species, synteny of the chromosomes appears to have been maintained.

    Tiporus queenslandicus sp. n. is described from NE Queensland. The new species is similar to T. undecimmaculatus (Clark, 1862) and T. giuliani (Watts, 1978) from the Northern Territory and north-western Australia but well characterized by its larger size, more elongate habitus, and form of median lobe and parameres. Tiporus queenslandicus sp. n. is a lotic species being collected from rest pools of intermittent creeks and rivers with a sandy bottom. Important species-defining characters (habitus, median lobe, paramere, protibia of male) are illustrated. Together with T. queenslandicus sp. n. the genus comprises now 13 species.

    2015-01-01

    Finger dislocations are common injuries that are often managed by emergency nurse practitioners. A systematic physical examination following these injuries is imperative to avoid complications. Radiographic views, including the anteroposterior, lateral, and oblique views, are imperative to evaluate these finger dislocations. A dorsal dislocation of the proximal interphalangeal (PIP) joint is the most common finger dislocation type often easily reduced. A volar PIP dislocation can often be difficult to reduce and may result in finger deformity. Finger dislocations should be reduced promptly. Referral to an orthopedic hand specialist is required if the dislocation is unable to be reduced or if the finger joint is unstable following reduction attempts.

    The proximity effect in diffusive normal-superconducting (NS) nano-structures is described by the Usadel equations for the electron pair correlations. We show that these equations obey a variational principle with a potential which generalizes the Ginzburg-Landau energy functional. We discuss simple examples of NS circuits using this formalism. In order to test the theoretical predictions of the Usadel equations, we have measured the density of states as a function of energy on a long N wire in contact with a S wire at one end, at different distances from the NS interface.

    Background Dengue has been a major public health concern in Australia since it re-emerged in Queensland in 1992–1993. We explored spatio-temporal characteristics of locally-acquired dengue cases in northern tropical Queensland, Australia during the period 1993–2012. Methods Locally-acquired notified cases of dengue were collected for northern tropical Queensland from 1993 to 2012. Descriptive spatial and temporal analyses were conducted using geographic information system tools and geostatistical techniques. Results 2,398 locally-acquired dengue cases were recorded in northern tropical Queensland during the study period. The areas affected by the dengue cases exhibited spatial and temporal variation over the study period. Notified cases of dengue occurred more frequently in autumn. Mapping of dengue by statistical local areas (census units) reveals the presence of substantial spatio-temporal variation over time and place. Statistically significant differences in dengue incidence rates among males and females (with more cases in females) (χ2 = 15.17, d.f. = 1, p<0.01). Differences were observed among age groups, but these were not statistically significant. There was a significant positive spatial autocorrelation of dengue incidence for the four sub-periods, with the Moran's I statistic ranging from 0.011 to 0.463 (p<0.01). Semi-variogram analysis and smoothed maps created from interpolation techniques indicate that the pattern of spatial autocorrelation was not homogeneous across the northern Queensland. Conclusions Tropical areas are potential high-risk areas for mosquito-borne diseases such as dengue. This study demonstrated that the locally-acquired dengue cases have exhibited a spatial and temporal variation over the past twenty years in northern tropical Queensland, Australia. Therefore, this study provides an impetus for further investigation of clusters and risk factors in these high-risk areas. PMID:24691549

  4. Congenital anomalies and proximity to landfill sites.

    2004-01-01

    The occurrence of congenital anomalies in proximity to municipal landfill sites in the Eastern Region (counties Dublin, Kildare, Wicklow) was examined by small area (district electoral division), distance and clustering tendancies in relation to 83 landfills, five of which were major sites. The study included 2136 cases of congenital anomaly, 37,487 births and 1423 controls between 1986 and 1990. For the more populous areas of the region 50% of the population lived within 2-3 km of a landfill and within 4-5 km for more rural areas. In the area-level analysis, the standardised prevalence ratios, empirical and full Bayesian modelling, and Kulldorff\\'s spatial scan statistic found no association between the residential area of cases and location of landfills. In the case control analysis, the mean distance of cases and controls from the nearest landfill was similar. The odds ratios of cases compared to controls for increasing distances from all landfills and major landfills showed no significant difference from the baseline value of 1. The kernel and K methods showed no tendency of cases to cluster in relationship to landfills. In conclusion, congenital anomalies were not found to occur more commonly in proximity to municipal landfills.

    We examined whether physical proximity to supermarkets or supermarket price was more strongly associated with obesity risk. The Seattle Obesity Study (SOS) collected and geocoded data on home addresses and food shopping destinations for a representative sample of adult residents of King County, Washington. Supermarkets were stratified into 3 price levels based on average cost of the market basket. Sociodemographic and health data were obtained from a telephone survey. Modified Poisson regression was used to test the associations between obesity and supermarket variables. Only 1 in 7 respondents reported shopping at the nearest supermarket. The risk of obesity was not associated with street network distances between home and the nearest supermarket or the supermarket that SOS participants reported as their primary food source. The type of supermarket, by price, was found to be inversely and significantly associated with obesity rates, even after adjusting for individual-level sociodemographic and lifestyle variables, and proximity measures (adjusted relative risk=0.34; 95% confidence interval=0.19, 0.63) Improving physical access to supermarkets may be one strategy to deal with the obesity epidemic; improving economic access to healthy foods is another.

    Anthropogenic climate change is a major factor driving shifts in the distributions of pests and invasive species. The Queensland fruit fly, Bactrocera tryoni Froggatt (Qfly), is the most economically damaging insect pest of Australia's horticultural industry, and its management is a key priority for plant protection and biosecurity. Identifying the extent to which climate change may alter the distribution of suitable habitat for Qfly is important for the development and continuation of effective monitoring programs, phytosanitary measures, and management strategies. We used Maxent, a species distribution model, to map suitable habitat for Qfly under current climate, and six climate scenarios for 2030, 2050 and 2070. Our results highlight that south-western Australia, northern regions of the Northern Territory, eastern Queensland, and much of south-eastern Australia are currently suitable for Qfly. This includes southern Victoria and eastern Tasmania, which are currently free of breeding populations. There is substantial agreement across future climate scenarios that most areas currently suitable will remain so until at least 2070. Our projections provide an initial estimate of the potential exposure of Australia's horticultural industry to Qfly as climate changes, highlighting the need for long-term vigilance across southern Australia to prevent further range expansion of this species.

    To describe the use of telemedicine in cancer care (teleoncology model of care) for rural patients in North Queensland. This is a descriptive study. Data on demographical and clinical factors were retrieved from the teleoncology database of Townsville Hospital and review of medical records for the period between May 2007 and May 2011. The medical oncologists at the Townsville Cancer Centre, a regional cancer centre in North Queensland, have been providing their services to rural hospitals in Townsville and Mt Isa districts via videoconferencing since 2007.   Cancer care delivery to rural sites via Townsville teleoncology model. The ability of the teleoncology model to provide the following services to rural towns: (i) specialist consultations; (ii) urgent specialist medical care; (iii) care for Indigenous patients; and (iv) remote supervision of chemotherapy administration. Between May 2007 and May 2011, 158 patients from 18 rural towns received a total of 745 consultations. Ten of these patients were consulted urgently and treatment plans initiated locally, avoiding interhospital transfers. Eighteen Indigenous patients received consultative services, being accompanied by more than four to six family members. Eighty-three patients received a range of intravenous and oral chemotherapy regimens in Mt Isa and oral agents in other towns through remote supervision by medical oncologists from Townsville. Teleoncology model of care allows rural and Indigenous cancer patients to receive specialist consultations and chemotherapy treatments closer to home, thus minimising the access difficulties faced by the rural sector. © 2012 The Authors.

    2002-01-01

    Economic valuations of the environmental resources provided by the waterways of South East Queensland are required for the evaluation of proposed environmental management strategies. Due to time and funding constraints it is unlikely that the environmental resources for each tributary of the river system will be subject to individual and explicit valuation. This paper reviews the literature about the validity of environmental benefit transfer, identifying the protocol for undertaking such a study. It then describes a study designed to transfer the estimated value of water quality improvements for the Bremer River to other waterways in South East Queensland. The study addresses some of the shortcomings of stated preference techniques to value the environment, including improving the quality of the information provided to survey respondents and the reliability of their responses by adopting a citizens' jury approach to the valuation exercise. In addition, the study is expected to provide the results in a form that will facilitate the estimation of a demand function for water quality improvements that will be meaningful for environmental value transfer to other sites with similar water quality issues.

    Full Text Available Australia has a very high rate of dog ownership, which in some circumstances may lead to exposure to zoonotic parasitic diseases from those companion animals. Domestic dog faecal samples (n = 300 were collected from public spaces and private property in the greater Rockhampton (Central Queensland region and tested for intestinal helminths and protozoa by direct microscopy, two flotation methods and a modified acid-fast stain for cryptosporidia. Intestinal parasites detected included hookworms (25%, Cystoisospora ohioensis complex (9%, Blastocystis hominis (3%, Giardia duodenalis (3%, Spirometra erinacei (1% and Toxocara canis (1%, Sarcocystis spp. (2%, Cryptosporidium spp. (2% and Cystoisospora canis (1%. One infection each with Trichuris vulpis, Dipylidium caninum and a protozoa belonging to the Entamoeba histolytica complex were identified. Sheather’s sucrose centrifugal flotation was more sensitive than saturated salt passive flotation, but no single test detected all cases of parasitic infection identified. The test methodologies employed are poor at recovering larva of Strongyloides stercoralis, Aleurostrongylus abstrussis and eggs of cestodes such as Echinococcus granulosis, so the potential presence of these parasites in Central Queensland domestic dogs cannot be excluded by this survey alone.

    While Indigenous people in Queensland have lower colorectal cancer (CRC) incidence and mortality than the rest of the population, CRC remains the third most frequent cancer among Australian Indigenous people overall. This study aimed to investigate patterns of care and survival between Indigenous and non-Indigenous Australians with CRC. Through a matched-cohort design we compared 80 Indigenous and 85 non-Indigenous people all diagnosed with CRC and treated in Queensland public hospitals during 1998-2004 (frequency matched on age, sex, geographical remoteness). We compared clinical and treatment data (Pearson's chi-square) and all-cause and cancer survival (Cox regression analysis). Indigenous patients with CRC were not significantly more likely to have comorbidity, advanced disease at diagnosis or less treatment than non-Indigenous people. There was also no statistically significant difference in all-cause survival (HR 1.14, 95% CI 0.69, 1.89) or cancer survival (HR 1.01, 95% CI 0.60, 1.69) between the two groups. Similar CRC mortality among Indigenous and other Australians may reflect both the lower incidence and adequate management. Increasing life expectancy and exposures to risk factors suggests that Indigenous people are vulnerable to a growing burden of CRC. Primary prevention and early detection will be of paramount importance to future CRC control among Indigenous Australians. Current CRC management must be maintained and include prevention measures to ensure that predicted increases in CRC burden are minimized. © 2014 Wiley Publishing Asia Pty Ltd.

    2016-07-01

    To understand health service access and needs of people who use performance and image enhancing drugs (PIED) in regional Queensland. Semi-structured interviews were conducted with 21 people (n = 19 men) who reported the use of a range of PIEDs, including anabolic-androgenic steroids, human chorionic gonadotropin, growth hormone, clenbuterol, tamoxifen, insulin and peptides. Participants reported accessing a range of services, including needle and syringe programs and pharmacies, for sterile injecting equipment. While PIEDs users attributed some stigma to needle and syringe programs, they were seen as an important service for injecting equipment. Participants reported receiving either positive care from health-care providers, such as general practitioners (GP), or having negative experiences due to the stigma attached with PIED use. Few participants reported disclosing their PIED use to their GP not only because of the concerns that their GP would no longer see them but also because they felt their GP was not knowledgeable about these substances. Participants in the study reported no difficulty in accessing health services based on living in a regional area, with their concern focused more upon how they were viewed and treated by service staff.

    2002-06-01

    This project investigated the aetiology of dental and oral trauma in a population in south-east Queensland. The literature shows there is a lack of dental trauma studies which are representative of the general Australian population. Twelve suburbs in the south-east district of Queensland were randomly selected according to population density in these suburbs for each 25th percentile. All dental clinics in these suburbs were eligible to participate. Patients presenting with dental and oral trauma were eligible to participate. A total of 197 patients presented with dental/oral trauma over a 12 month period. The age of patients ranged from 1-64 years whilst the most frequently presenting age group was 6-10 years. There was a total of 363 injured teeth with an average of 1.8 injured teeth per patient. Males significantly outnumbered females in the incidence of trauma. The highest frequency of trauma occurred in the 6-10 year age group. Most injuries in this group occurred while playing or riding bicycles. In the next most prevalent trauma group, 16-20 years, trauma occurred as a result of fighting and playing sport. Overall, males significantly outnumbered females by approximately 1.8:1.0. The majority of injuries in the deciduous dentition were to periodontal tissues. In the secondary dentition most injuries were to hard dental tissue and pulp.

    2017-08-01

    The 1882 transit of Venus offered the final opportunity for astronomers to use these rare events to pin down the distance from the Earth to the Sun. A British party based itself in southern Queensland, but total cloud cover prevented any observations being made on the critical day. In this paper we trace the preparations of the British party, and then show how they laid the foundations for the development of astronomy in Queensland by selling their two 6-in Cooke refractors before returning to Britain. Both instruments were purchased by a Townsville amateur astronomer, Edwin Norris, and although he installed one in an observatory, he made little use of it. However, he subsequently sold the other telescope to J. Ewen Davidson of Mackay, who also erected an obser-vatory for it. Davidson then used his instrument for cometary astronomy, in the process discovering two new comets, one of which now bears his name. Unfortunately, recent attempts to track down the present whereabouts of the two telescopes have failed.

    Necrosis of the humeral head, infections and non-unions are among the most dangerous and difficult-to-treat complications of proximal humeral fractures. The aim of this work was to analyse in detail non-unions and post-traumatic bone defects and to suggest an algorithm of care. Treatment options are based not only on the radiological frame, but also according to a detailed analysis of the patient, who is classified using a risk factor analysis. This method enables the surgeon to choose the most suitable treatment for the patient, thereby facilitating return of function in the shortest possible time. The treatment of such serious complications requires the surgeon to be knowledgeable about the following possible solutions: increased mechanical stability; biological stimulation; and reconstructive techniques in two steps, with application of biotechnologies and prosthetic substitution.

    Full Text Available Whilst extensive clearance of forests in the eastern Australian Brigalow Belt Bioregion (BBB has occurred since European settlement, appropriate management of those that are regenerating can facilitate restoration of biomass (carbon and biodiversity to levels typical of relatively undisturbed or remnant formations. However, maps of forests are different stages of regeneration are needed to facilitate restoration planning, including prevention of further re-clearing. Focusing on the Tara Downs subregion of the BBB and on forests with brigalow (Acacia harpophylla as a component, this research establishes a method for differentiating and mapping early, intermediate and remnant growth stages from Japan Aerospace Exploration Agency (JAXA Advanced Land Observing Satellite (ALOS Phased-Array L-band Synthetic Aperture Radar (PALSAR Fine Beam Dual (FBD L-band HH- and HV-polarisation backscatter and Landsat-derived Foliage Projective Cover (FPC. Using inventory data collected from 74 plots, located in the Tara Downs subregion, forests were assigned to one of three regrowth stages based on their height and cover relative to that of undisturbed stands. The image data were then segmented into objects with each assigned to a growth stage by comparing the distributions of L-band HV and HH polarisation backscatter and FPC to that of reference distributions using a z-test. Comparison with independent assessments of growth stage, based on time-series analysis of aerial photography and SPOT images, established an overall accuracy of > 70%, with this increasing to 90% when intermediate regrowth was excluded and only early-stage regrowth and remnant classes were considered. The proposed method can be adapted to respond to amendments to user-definitions of growth stage and, as regional mosaics of ALOS PALSAR and Landsat FPC are available for Queensland, has application across the state.

    Simultaneous personal measurements of the occupational ultraviolet exposure weighted to the International Commission on Non-Ionising Radiation Protection hazard sensitivity spectrum (UVICNIRP) were made over a five week period (44 person-days) in the second half of the summer school term of 2012 in Queensland, Australia for individual high school teachers located at latitudes of 27.5°S and 23.5°S. These teachers were employed for the duration of the study in a predominately indoor classroom teaching role, excluding mandatory periods of lunch time yard duty and school sport supervisions. Data is presented from personal measurements made to the shirt collar using polyphenylene oxide (PPO) film UV dosimeters. UVICNIRP exposure data is presented for each week of the study period for the shirt collar measurement site and are further expressed relative to the measured ambient horizontal plane exposure. Personal exposures were correlated with time outdoors, showing a higher exposure trend on days when teachers were required to supervise outdoor areas for more than 2h per week (mean daily exposure: 168Jm(-2)UVICNIRP±5Jm(-2) (1σ)) compared to the study average (mean daily exposure: 115Jm(-2)UVICNIRP±91Jm(-2) (1σ)). Time spent in an open playground environment was found to be the most critical factor influencing the occupational UVICNIRP exposure. A linear model was developed showing a correlation (R(2)=0.77) between the time teachers spent on yard duty and UVICNIRP exposure, expressed relative to ambient. The research findings indicate a greater reduction in personal exposure can be achieved by timetabling for yard duty periods in playground areas which offer more shade from trees and surrounding buildings. All mean daily personal exposures measured at the shirt collar site were higher than the ICNIRP occupational daily exposure limit of 30Jm(-2) for outdoor workers. Copyright © 2014 Elsevier B.V.

    A peri-operative bay was created to treat all patients with proximal femoral fractures admitted to one trauma ward at the Queen's Medical Centre, Nottingham. All patients had urinary catheterisation and their fluid intake and output was recorded; patients had daily blood tests and were cared for on pressure-relieving mattresses. In addition, a study day was provided for all nursing staff on the management of patients with proximal femoral fractures. These measures resulted in a significant decrease in the incidence of acute kidney injury, reduced the length of hospital stay for patients on this ward and reduced the numbers of falls and pressure-related injuries for these patients.

    Optical proximity sensing techniques which could be used to help control the critical grasping phase of a remote manipulation are described. The proximity sensors described use a triangulation geometry to detect a surface located in a pre-determined region. The design of the proximity sensors themselves is discussed, as well as their application to manipulator control with a local control loop, and possibilities for future development are discussed.

  2. Children's Attentional Processing of Mother and Proximity Seeking.

    Guy Bosmans

    Full Text Available Attachment expectations regarding the availability of mother as a source for support are supposed to influence distressed children's support seeking behavior. Because research is needed to better understand the mechanisms related to support seeking behavior, this study tested the hypothesis that the cognitive processing of mother-related information is linked to proximity and support seeking behavior. Uncertainty in maternal support has been shown to be characterized by a biased attentional encoding of mother, reducing the breadth of children's attentional field around her. We investigated whether this attentional bias is related to how long distressed children wait before seeking their mother's proximity. Thirty-three children (9-11 years participated in this study that consisted of experimental tasks to measure attentional breadth and to observe proximity seeking behavior and of questionnaires to measure confidence in maternal support and experienced distress. Results suggested that distressed children with a more narrow attentional field around their mother wait longer to seek her proximity. Key Message: These findings provide a first support for the hypothesis that the attentional processing of mother is related to children's attachment behavior.

    Full Text Available Australian bat lyssavirus (ABLV belongs to the genus Lyssavirus which also includes classic rabies virus and the European lyssaviruses. To date, the only three known human ABLV cases, all fatal, have been reported from Queensland, Australia. ABLV is widely distributed in Australian bats, and any bite or scratch from an Australian bat is considered a potential exposure to ABLV.Potential exposure to ABLV has been a notifiable condition in Queensland since 2005. We analysed notification data for potential exposures occurring between 2009 and 2014. There were 1,515 potential exposures to ABLV notified in Queensland, with an average annual notification rate of 5.6 per 100,000 population per year. The majority of notified individuals (96% were potentially exposed to ABLV via bats, with a small number of cases potentially exposed via two ABLV infected horses and an ABLV infected human. The most common routes of potential exposure were through bat scratches (47% or bites (37%, with less common routes being mucous membrane/broken skin exposure to bat saliva/brain tissue (2.2%. Intentional handling of bats by the general public was the major cause of potential exposures (56% of notifications. Examples of these potential exposures included people attempting to rescue bats caught in barbed wire fences/fruit tree netting, or attempting to remove bats from a home. Following potential exposures, 1,399 cases (92% were recorded as having appropriate post-exposure prophylaxis (PEP as defined in national guidelines, with the remainder having documentation of refusal or incomplete PEP. Up to a quarter of notifications occurred after two days from the potential exposure, but with some delays being more than three weeks. Of 393 bats available for testing during the reporting period, 20 (5.1% had ABLV detected, including four species of megabats (all flying foxes and one species of microbats (yellow-bellied sheathtail bat.Public health strategies should address the

This longitudinal study investigates the association between prostate cancer diagnostic and treatment outcomes and key area-level characteristics and individual-level demographic, clinical and psychosocial factors. Methods/Design A total of 1064 men diagnosed with prostate cancer between February 2005 and July 2007 were recruited through hospital-based urology outpatient clinics and private practices in the centres of Brisbane, Townsville and Mackay (82% of those referred. Additional clinical and diagnostic information for all 6609 men diagnosed with prostate cancer in Queensland during the study period was obtained via the population-based Queensland Cancer Registry. Respondent data are collected using telephone and self-administered questionnaires at pre-treatment and at 2 months, 6 months, 12 months, 24 months, 36 months, 48 months and 60 months post-treatment. Assessments include demographics, medical history, patterns of care, disease and treatment characteristics together with outcomes associated with prostate cancer, as well as information about quality of life and psychological adjustment. Complementary detailed treatment information is abstracted from participants' medical records held in hospitals and private treatment facilities and collated with health service utilisation data obtained from Medicare Australia. Information about the characteristics of geographical areas is being obtained from data custodians such as the Australian Bureau of Statistics. Geo-coding and spatial technology will be used to calculate road travel distances from patients' residences to treatment centres.

    The survival inequality faced by Indigenous Australians after a cancer diagnosis is well documented; what is less understood is whether this inequality has changed over time and what this means in terms of the impact a cancer diagnosis has on Indigenous people. Survival information for all patients identified as either Indigenous (n=3168) or non-Indigenous (n=211,615) and diagnosed in Queensland between 1997 and 2012 were obtained from the Queensland Cancer Registry, with mortality followed up to 31st December, 2013. Flexible parametric survival models were used to quantify changes in the cause-specific survival inequalities and the number of lives that might be saved if these inequalities were removed. Among Indigenous cancer patients, the 5-year cause-specific survival (adjusted by age, sex and broad cancer type) increased from 52.9% in 1997-2006 to 58.6% in 2007-2012, while it improved from 61.0% to 64.9% among non-Indigenous patients. This meant that the adjusted 5-year comparative survival ratio (Indigenous: non-Indigenous) increased from 0.87 [0.83-0.88] to 0.89 [0.87-0.93], with similar improvements in the 1-year comparative survival. Using a simulated cohort corresponding to the number and age-distribution of Indigenous people diagnosed with cancer in Queensland each year (n=300), based on the 1997-2006 cohort mortality rates, 35 of the 170 deaths due to cancer (21%) expected within five years of diagnosis were due to the Indigenous: non-Indigenous survival inequality. This percentage was similar when applying 2007-2012 cohort mortality rates (19%; 27 out of 140 deaths). Indigenous people diagnosed with cancer still face a poorer survival outlook than their non-Indigenous counterparts, particularly in the first year after diagnosis. The improving survival outcomes among both Indigenous and non-Indigenous cancer patients, and the decreasing absolute impact of the Indigenous survival disadvantage, should provide increased motivation to continue and enhance

    The doctor shortage in Australia generally, and the rural shortage in particular, has led to an increase in medical schools, medical places and rural training. If effective, these strategies will first impact on the intern workforce. We studied the source of interns in Queensland. Analysis of number, source and location of interns by Rural, Remote and Metropolitan Area (RRMA) classification (an index of remoteness) from university and health department records (2003-2008). Odds ratios compared the likelihood of intern supply from Queensland universities and rural clinical schools. Most interns in Queensland graduated from Queensland universities in 2007 (287 [72%]) and 2008 (344 [84%]). Proportions increased across all three RRMA groups from: 82% to 93% in RRMA1; 56% to 68% in RRMA2 and 67% to 79% in RRMA3. The University of Queensland (UQ) provides most interns in all RRMA locations including RRMA3, and this increased from 2007 (n = 33 [35%]) to 2008 (n = 57 [58%]). Interns from interstate decreased from 61 (15%) in 2007 to 40 (10%) in 2008. Interns from overseas fell from 53 (13%) in 2007 to 27 (7%) in 2008. Rural clinical schools compared with traditional urban-based schools were more likely to supply interns to RRMA3 than RRMA1 hospitals in 2007 (OR, 8.8; 95% CI, 4.6-16.7; P self-sufficiency in intern supply and will achieve this in the next few years. Rural clinical schools are playing an important role in producing interns for RRMA3 hospitals. Due to its large cohort, UQ remains the major provider across all RRMA groups.

    In 2014, northern Queensland crayfish from farms affected by particularly transportation and translocation stress, started to die with mortality reaching 20-40% after about three weeks and then mortalities subsided. Crayfish from 1 farm had 65% mortalities within 11 weeks. With histological examination of broodstock and juveniles, the muscle fibres were fractured with haemocytic infiltration reminiscent of viral infection or vitamin E/selenium deficiencies. Sequence dependent and independent PCRs failed to identify a viral aetiology. However, the whole transcriptomes of a case crayfish and an unaffected crayfish from a different population were assembled producing over 500,000 contigs. The complete sequence of a positive sense, single stranded RNA virus (+ve ssRNA virus; 9933bp) and the large and medium segments of a bunya-like virus were detected. Transcript back-mapping and newly developed PCRs indicated that the viruses were in the case crayfish but not the control crayfish. The +ve ssRNA virus is clearly in the order Picornavirales, marginally in the genus Iflavirus in a clade of Chinese and Northern American terrestrial arthropod viruses. The internal Picornavirales motifs; RNA-dependent RNA polymerase, helicase (P-loop) and 2 viral capsids genes were easily identified. This is the first iflavirus identified from crustacea and is named Chequa iflavirus. Whether these viruses are responsible for the stress-related mortalities is unproven but the Chequa virus' role seems limited as it appears it has been present in crayfish from at least the early 1990s; unless low-grade, chronic mortalities have been largely unnoticed.

    To describe the processes undertaken to maximise cultural competence in a complex research project and illustrate how this enhanced the quality of the research and impact of the research outcomes. An epidemiological survey of the mental health of Indigenous people in custody in Queensland was conducted using culturally informed research processes. The research process that enhanced cultural competence is described. The research outcomes were positive in terms of participant and community experiences, participation rates, publications and other research outputs, capacity building and translation of research findings. This paper describes in practical terms how to conduct culturally informed research and how this approach enhanced the scientific rigour of a complex Indigenous health research project. Indigenous health research should be conducted using a culturally competent method. © The Royal Australian and New Zealand College of Psychiatrists 2015.

    Full Text Available This paper examines the rapid and ad hoc development and interactions of participative citizen communities during acute events, using the examples of the 2011 floods in Queensland, Australia, and the global controversy surrounding Wikileaks and its spokesman, Julian Assange. The self-organising community responses to such events which can be observed in these cases bypass or leapfrog, at least temporarily, most organisational or administrative hurdles which may otherwise frustrate the establishment of online communities; they fast-track the processes of community development and structuration. By understanding them as a form of rapid prototyping, e-democracy initiatives can draw important lessons from observing the community activities around such acute events.

    The purpose of this study was to investigate the epidemiology of tobacco smoking among dentists in Queensland, Australia. We utilized an anonymous, self-reporting questionnaire which was posted to 400 dentists during 2004. The overall response rate was 72.1%, among whom the prevalence of current smoking was estimated to be 3.9% (95%CI: 2.2-6.9), with a further 11.0% being ex-smokers (95%CI: 7.9-15.2). Smoking rates varied by age, with 6.1% of dentists aged younger than 30 years who were smokers. The lowest smoking prevalence was seen among dentists aged between 30 and 40 years (1.4%), and the highest among those aged over 60 years (7.1%). Regarding weekly work hours, the highest smoking prevalence was seen among dentists who worked between 25 and 35 hrs per week (6.8%). Ex-smokers were more likely to work less than 25 hrs per week (21.7%). Smoking rates also varied by career length, with the lowest prevalence among dentists who had worked 10 to 20 years (1.3%) and the highest rate among those who had worked over 40 years (6.7%). A similar trend was revealed for ex-smokers, with prevalence rates of 1.7% and 33.3%, respectively. Overall, our study suggests that the prevalence of smoking is rather low among Queensland dentists. As the distribution of smoking was not uniform however, future preventive measures will need to consider the individual situation of dentists who smoke, particularly those in the older age groups.

    To conduct a cost analysis of a telemedicine model for cancer care (teleoncology) in northern Queensland, Australia, compared with the usual model of care from the perspective of the Townsville and other participating hospital and health services. Retrospective cost-savings analysis; and a one-way sensitivity analysis performed to test the robustness of findings in net savings. Records of all patients managed by means of teleoncology at the Townsville Cancer Centre (TCC) and its six rural satellite centres in northern Queensland, Australia between 1 March 2007 and 30 November 2011. Costs for set-up and staffing to manage the service, and savings from avoidance of travel expenses for specialist oncologists, patients and their escorts, and for aeromedical retrievals. There were 605 teleoncology consultations with 147 patients over 56 months, at a total cost of $442 276. The cost for project establishment was $36 000, equipment/maintenance was $143 271, and staff was $261 520. The estimated travel expense avoided was $762 394; this figure included the costs of travel for patients and escorts of $658 760, aeromedical retrievals of $52 400 and travel for specialists of $47 634, as well as an estimate of accommodation costs for a proportion of patients of $3600. This resulted in a net saving of $320 118. Costs would have to increase by 72% to negate the savings. The teleoncology model of care at the TCC resulted in net savings, mainly due to avoidance of travel costs. Such savings could be redirected to enhancing rural resources and service capabilities. This teleoncology model is applicable to geographically distant areas requiring lengthy travel.

    This research gathered information in 2004 about psychological services provided to five rural communities located in South-west Queensland, Australia. Specifically, the aims of the project were to: (i) undertake an audit of existing psychological services; and (ii) determine the need for psychological services as perceived by providers of current services. Potential providers of psychological services were contacted to confirm the nature and extent of their provision of psychological support to target communities. Thirty organisations met the definition of service providers offering assessment or intervention by qualified and/or experienced persons. Data were collected by semi-structured telephone interviews with 44 employees of the service providers. The one main publicly-funded provider of services to the region offered limited services to the communities. Although some counselling was provided by social workers attached to the allied health program, for patients to be supported by the mental health sector of this service, they must have had moderate to severe mental illness. Regular, reliable and accessible psychological support for other conditions was limited largely to services provided by non-government organisations (NGOs) which are often constrained by continuity of funds. Counselling for alcohol and drug misuse, women's issues, sexual abuse, and crisis support were the most commonly identified unmet needs across the target communities. Difficulties in attracting experienced personnel to work in rural communities were reported. This was exacerbated by lack of job security brought about by short term funding to the NGOs. In general, unqualified counsellors were recognised as providing valuable services. There are limited psychological support services provided to these South-west Queensland communities. For available services, there are strict criteria for entry, limited accessibility and availability or lack of continuity owing to short-term funding

    Women born outside Australia make up more than a fifth of the Queensland birthing population and like migrants in other parts of the world face the challenges of cultural dislocation and possible language barriers. Recognising that labour and birth are major life events the aim was to investigate the experiences of these women in comparison to native-born English speaking women. Secondary analysis of data from a population based survey of women who had recently birthed in Queensland. Self-reported clinical outcomes and quality of interpersonal care of 481 women born outside Australia who spoke a language other than English at home were compared with those of 5569 Australian born women speaking only English. After adjustment for demographic factors and type of birthing facility, women born in another country were less likely to be induced, but more likely to have constant electronic fetal monitoring (EFM), to give birth lying on their back or side, and to have an episiotomy. Most women felt that they were treated as an individual and with kindness and respect. However, women born outside Australia were less likely to report being looked after 'very well' during labour and birth and to be more critical of some aspects of care. In comparing the labour and birth experiences of women born outside the country who spoke another language with native-born English speaking women, the present study presents a largely positive picture. However, there were some marked differences in both clinical and interpersonal aspects of care. Copyright © 2014 Australian College of Midwives. Published by Elsevier Ltd. All rights reserved.

    2016-03-15

    The extinct hemipteran family Dysmorphoptilidae was a major component of the Triassic insect fauna of Queensland preserved at the Denmark Hill, Dinmore, Mount Crosby and Gayndah fossil insect sites. A total of 13 species have now been identified, of which eight species in five genera were examined in the first part of this revision. This second part revises the remaining five species in three genera. Eoscartoides Evans, 1956 (= Mesonirvana Evans, 1956, syn. nov.), comprising Eoscartoides bryani Evans, 1956 (= Mesonirvana abrupta Evans, 1956, syn. nov.) (Mount Crosby), Eoscartoides orthocladus (Tillyard, 1922) comb. nov. (Denmark Hill), and Eoscartoides dmitryi sp. nov. (Dinmore), is distinguished by a strongly developed arc-like strigil in the basal costal space, a very short stem of RA, and a deeply forked M1+2. The monotypic Eoscarterella Evans, 1956, with type species Eoscarterella media Evans, 1956 (Mount Crosby), has a strongly lobate tegmen with peculiar surface sculpture and M1+2 simple. Eoscartoides and Eoscarterella differ from most dysmorphoptilids in having more or less lobate tegmina with even margins (without the antero-apical emargination so typical of the family), as well as the early entry of RA1 into the costal margin and the associated extensive and antero-apically positioned RA2. These characters are also shared with two other dysmorphoptilids, the Australian Permian Belmontocarta Evans and an unnamed Triassic species from Kyrgyzstan, and the four thus form a distinct subgroup within the family. On the other hand, the monotypic Trifidella Evans, 1956 (= Alotrifidus Evans, 1956, syn. nov.), with type species Trifidella perfecta Evans, 1956 (= Alotrifidus interruptus Evans, 1956, syn. nov.) (Mount Crosby), is a more typical dysmorphoptilid with a distinct emargination, RA entering the margin much more apically, and RA2 of limited extent. Trifidella is presumably the sister of the Queensland Triassic Dysmorphoptiloides Evans, sharing the basal

  19. Pliocene paleoenvironments of southeastern Queensland, Australia inferred from stable isotopes of marsupial tooth enamel.

    Shaena Montanari

    Full Text Available The Chinchilla Local Fauna is a diverse assemblage of both terrestrial and aquatic Pliocene vertebrates from the fluviatile Chinchilla Sand deposits of southeastern Queensland, Australia. It represents one of Australia's few but exceptionally rich Pliocene vertebrate localities, and as such is an important source of paleoecological data concerning Pliocene environmental changes and its effects on ecosystems. Prior inferences about the paleoenvironment of this locality made on the basis of qualitative observations have ranged from grassland to open woodland to wetland. Examination of the carbon and oxygen isotopes in the tooth enamel of marsupials from this site represents a quantitative method for inferring the paleoenvironments and paleoecology of the fossil fauna. Results from Chinchilla show that Protemnodon sp. indet. consumed both C3 and C4 photosynthesis plant types (mean δ(13C = -14.5±2.0‰, and therefore probably occupied a mixed vegetation environment. Macropus sp. indet. from Chinchilla also consumed a mixed diet of both C3 and C4 plants, with more of a tendency for C4 plant consumption (mean δ(13C = -10.3±2.3‰. Interestingly, their isotopic dietary signature is more consistent with tropical and temperate kangaroo communities than the sub-tropical communities found around Chinchilla today. Other genera sampled in this study include the extinct kangaroo Troposodon sp. indet. and the fossil diprotodontid Euryzygoma dunense each of which appear to have occupied distinct dietary niches. This study suggests that southeastern Queensland hosted a mosaic of tropical forests, wetlands and grasslands during the Pliocene and was much less arid than previously thought.

    Biological soil crusts (biocrusts) are a common element of the Queensland (Australia) dry savannah ecosystem and are composed of cyanobacteria, algae, lichens, bryophytes, fungi and heterotrophic bacteria. Here we report how the CO2 gas exchange of the cyanobacteria-dominated biocrust type from Boodjamulla National Park in the north Queensland Gulf Savannah responds to the pronounced climatic seasonality and on their quality as a carbon sink using a semi-automatic cuvette system. The dominant cyanobacteria are the filamentous species Symplocastrum purpurascens together with Scytonema sp. Metabolic activity was recorded between 1 July 2010 and 30 June 2011, during which CO2 exchange was only evident from November 2010 until mid-April 2011, representative of 23.6 % of the 1-year recording period. In November at the onset of the wet season, the first month (November) and the last month (April) of activity had pronounced respiratory loss of CO2. The metabolic active period accounted for 25 % of the wet season and of that period 48.6 % was net photosynthesis (NP) and 51.4 % dark respiration (DR). During the time of NP, net photosynthetic uptake of CO2 during daylight hours was reduced by 32.6 % due to water supersaturation. In total, the biocrust fixed 229.09 mmol CO2 m-2 yr-1, corresponding to an annual carbon gain of 2.75 g m-2 yr-1. Due to malfunction of the automatic cuvette system, data from September and October 2010 together with some days in November and December 2010 could not be analysed for NP and DR. Based on climatic and gas exchange data from November 2010, an estimated loss of 88 mmol CO2 m-2 was found for the 2 months, resulting in corrected annual rates of 143.1 mmol CO2 m-2 yr-1, equivalent to a carbon gain of 1.7 g m-2 yr-1. The bulk of the net photosynthetic activity occurred above a relative humidity of 42 %, indicating a suitable climatic combination of temperature, water availability and light intensity well above 200 µmol photons m-2 s-1

    A major area in cancer therapy is the search for protective strategies against cisplatin-induced nephrotoxicity. We investigated the protective effect of cilastatin on cisplatin-induced injury to renal proximal tubular cells. Cilastatin is a specific inhibitor of renal dehydrodipeptidase I (DHP-I), which prevents hydrolysis of imipenem and its accumulation in the proximal tubule. Primary cultures of proximal cells were treated with cisplatin (1-30 microM) in the presence or absence of cilastatin (200 microg/ml). Apoptosis and mitochondrial injury were assessed by different techniques. Cisplatin uptake and DNA binding were measured by inductively coupled plasma spectrometry. HeLa cells were used to control the effect of cilastatin on the tumoricidal activity of cisplatin. Cisplatin increased cell death, apoptotic-like morphology, caspase activation, and mitochondrial injury in proximal tubular cells in a dose- and time-dependent way. Concomitant treatment with cilastatin reduced cisplatin-induced changes. Cilastatin also reduced the DNA-bound platinum but did not modify cisplatin-dependent up-regulation of death receptors (Fas) or ligands (tumor necrosis factor alpha, Fas ligand). In contrast, cilastatin did not show any effects on cisplatin-treated HeLa cells. Renal DHP-I was virtually absent in HeLa cells. Cilastatin attenuates cisplatin-induced cell death in proximal tubular cells without reducing the cytotoxic activity of cisplatin in tumor cells. Our findings suggest that the affinity of cilastatin for renal dipeptidase makes this effect specific for proximal tubular cells and may be related to a reduction in intracellular drug accumulation. Therefore, cilastatin administration might represent a novel strategy in the prevention of cisplatin-induced acute renal injury.

    Proximal ulna fractures account for 20% of all proximal forearm fractures. Many treatment options are available for such fractures, such as cast immobilisation, plate and screw fixation, tension band wiring and intramedullary screw fixation, depending on the fracture pattern. Due to the subcutaneous nature of the proximal forearm, it is vulnerable to open injuries over the dorsal aspect of the proximal ulna. This may in turn prove challenging, as it is critical to obtain adequate soft tissue coverage to reduce the risk of implant exposure and bony infections. We herein describe a patient with a Gustillo III-B open fracture of the proximal ulna, treated with minimally invasive intramedullary screw fixation using a 6.0-mm cannulated headless titanium compression screw (FusiFIX, Péronnas, France).

    Psychologists have examined the many psychological barriers to both climate change belief and concern. One barrier is the belief that climate change is too uncertain, and likely to happen in distant places and times, to people unlike oneself. Related to this perceived psychological distance of climate change, studies have shown that direct experience of the effects of climate change increases climate change concern. The present study examined the relationship between physical proximity to the coastline and climate change belief, as proximity may be related to experiencing or anticipating the effects of climate change such as sea-level rise. We show, in a national probability sample of 5,815 New Zealanders, that people living in closer proximity to the shoreline expressed greater belief that climate change is real and greater support for government regulation of carbon emissions. This proximity effect held when adjusting for height above sea level and regional poverty. The model also included individual differences in respondents' sex, age, education, political orientation, and wealth. The results indicate that physical place plays a role in the psychological acceptance of climate change, perhaps because the effects of climate change become more concrete and local.

  11. Proximal Alternating Direction Method with Relaxed Proximal Parameters for the Least Squares Covariance Adjustment Problem

    2014-01-01

    Full Text Available We consider the problem of seeking a symmetric positive semidefinite matrix in a closed convex set to approximate a given matrix. This problem may arise in several areas of numerical linear algebra or come from finance industry or statistics and thus has many applications. For solving this class of matrix optimization problems, many methods have been proposed in the literature. The proximal alternating direction method is one of those methods which can be easily applied to solve these matrix optimization problems. Generally, the proximal parameters of the proximal alternating direction method are greater than zero. In this paper, we conclude that the restriction on the proximal parameters can be relaxed for solving this kind of matrix optimization problems. Numerical experiments also show that the proximal alternating direction method with the relaxed proximal parameters is convergent and generally has a better performance than the classical proximal alternating direction method.

    Interactions among neighboring cells underpin many physiological processes ranging from early development to immune responses. When these interactions do not function properly, numerous pathologies, including infection and cancer, can result. Molecular imaging technologies, especially optical imaging, are uniquely suited to illuminate complex cellular interactions within the context of living tissues in the body. However, no tools yet exist that allow the detection of microscopic events, such as two cells coming into close proximity, on a global, whole-animal scale. We report here a broadly applicable, longitudinal strategy for probing interactions among cells in living subjects. This approach relies on the generation of bioluminescent light when two distinct cell populations come into close proximity, with the intensity of the optical signal correlating with relative cellular location. We demonstrate the ability of this reporter strategy to gauge cell-cell proximity in culture models in vitro and then evaluate this approach for imaging tumor-immune cell interactions using a murine breast cancer model. In these studies, our imaging strategy enabled the facile visualization of features that are otherwise difficult to observe with conventional imaging techniques, including detection of micrometastatic lesions and potential sites of tumor immunosurveillance. This proximity reporter will facilitate probing of numerous types of cell-cell interactions and will stimulate the development of similar techniques to detect rare events and pathological processes in live animals.

    This paperexplores the patterns ofpatients'accessingsix Aboriginal and Islander CommunityControlled Health Services (AICCHSs) in Queensland. Between August 2011 and February 2014, 26199 patients made at least one visit over a 2-year period prior to at least one of six Queensland AICCHS - one urban service (RA 1) in south-east Queensland, and five services in regional towns (RA 3) in Far North Queensland. Geospatial mapping of addresses for these registered patients was undertaken. The outcomes analysed included travel times to, the proportion of catchment populations using each AICCHS and an assessment of alternative mainstream general practice availability to these patients was made. In brief, the use of AICCHS was higher than Australian Bureau of Statistics census data would suggest. Approximately 20% of clients travel more than 30min to seek Aboriginal Health services, but only 8% of patients travelled longer than 60min. In the major city site, many other general practitioner (GP) services were bypassed. The data suggest Aboriginal and Islander patients in Queensland appear to value community-controlled primary care services. The number of Indigenous clients in regional locations in the Far North Queensland registered with services is often higher than the estimated resident population numbers.

    The treatment of unstable displaced proximal humeral fractures, especially in the elderly, remains controversial. The objective of the present prospective, multicenter, observational study was to evaluate the functional outcome and the complication rate after open reduction and internal fixation of proximal humeral fractures with use of a locking proximal humeral plate. One hundred and eighty-seven patients (mean age, 62.9 +/- 15.7 years) with an acute proximal humeral fracture were managed with open reduction and internal fixation with a locking proximal humeral plate. At the three-month, six month,and one-year follow-up examinations, 165 (88%), 158 (84%), and 155 (83%) of the 187 patients were assessed with regard to pain, shoulder mobility, and strength. The Constant score was determined at each interval, and the Disabilities of the Arm, Shoulder and Hand (DASH) score was determined for the injured and contralateral extremities at the time of the one-year follow-up. Between three months and one year, the mean range of motion and the mean Constant score for the injured shoulders improved substantially. Twelve months after surgery, the mean Constant score for the injured side was 70.6 +/- 13.7 points, corresponding to 85.1% +/- 14.0% of the score for the contralateral side. The mean DASH score at the time of the one-year follow-up was 15.2 +/- 16.8 points. Sixty-two complications were encountered in fifty-two (34%) of 155 patients at the time of the one-year follow-up. Twenty-five complications (40%) were related to incorrect surgical technique and were present at the end of the operative procedure. The most common complication, noted in twenty-one (14%) of 155 patients, was intraoperative screw perforation of the humeral head. Twenty-nine patients (19%) had an unplanned second operation within twelve months after the fracture.

    2015-06-01

    Queensland Health established a Ministerial Taskforce to consult on and make recommendations for the expansion of the scope ofpractice of allied health roles. This paper describes the findings from the stakeholder consultation. The Ministerial Taskforce was chaired by the Assistant Minister for Health and included high-level representation from allied health, nursing, medicine, unions, consumers and universities. Widespread engagement was undertaken with stakeholders representing staff from a wide cross-section of health service provision, training and unions. Participants also tendered evidence of models incorporating full-scope and extended scope tasks undertaken by allied health professionals. The consultation incorporated 444 written submissions and verbal feedback from over 200 participants. The findings suggest that full scope of practice is often restricted within the Queensland public health system, resulting in underuse of allied health capacity and workforce inefficiencies. However, numerous opportunities exist to enhance patient care by extending current roles, including prescribing and administering medications, requesting investigations, conducting procedures and reporting results. The support needed to realise these opportunities includes: designing patient-centred models of service delivery (including better hours of operation and delegation to support staff); leadership and culture change; funding incentives; appropriate education and training; and clarifying responsibility, accountability and liability for outcomes. The taskforce developed a series of recommendations and an implementation strategy to operationalise the changes. The Ministerial Taskforce was an effective and efficient process for capturing broad-based engagement for workforce change while ensuring high-level support and involving potential adversaries in the decision-mking processes. What is known about the topic? Anecdotal evidence exists to suggest that allied health professionals

    Threatened species in rainforests may be vulnerable to climate change, because of their potentially narrow thermal tolerances, small population sizes and restricted distributions. This study modelled climate induced changes on the habitat distribution of the endangered rainforest plant Triunia robusta, endemic to southeast Queensland, Australia. Species distribution models were developed for eastern Australia at 250 m grids and southeast Queensland at 25 m grids using ground-truthed presence records and environmental predictor data. The species’ habitat distribution under the current climate was modelled, and the future potential habitat distributions were projected for the epochs 2030, 2050 and 2070. The eastern Australia model identified several spatially disjunct, broad habitat areas of coastal eastern Australia consistent with the current distribution of rainforests, and projected a southward and upslope contraction driven mainly by average temperatures exceeding current range limits. The southeast Queensland models suggest a dramatic upslope contraction toward locations where the majority of known populations are found. Populations located in the Sunshine Coast hinterland, consistent with past rainforest refugia, are likely to persist long-term. Upgrading the level of protection for less formal nature reserves containing viable populations is a high priority to better protect refugial T. robusta populations with respect to climate change.

  13. Proximity sensor system development. CRADA final report

    Lockheed Martin Energy Research Corporation (LMERC) and Merritt Systems, Inc. (MSI) entered into a Cooperative Research and Development Agreement (CRADA) for the development and demonstration of a compact, modular proximity sensing system suitable for application to a wide class of manipulator systems operated in support of environmental restoration and waste management activities. In teleoperated modes, proximity sensing provides the manipulator operator continuous information regarding the proximity of the manipulator to objects in the workspace. In teleoperated and robotic modes, proximity sensing provides added safety through the implementation of active whole arm collision avoidance capabilities. Oak Ridge National Laboratory (ORNL), managed by LMERC for the United States Department of Energy (DOE), has developed an application specific integrated circuit (ASIC) design for the electronics required to support a modular whole arm proximity sensing system based on the use of capacitive sensors developed at Sandia National Laboratories. The use of ASIC technology greatly reduces the size of the electronics required to support the selected sensor types allowing deployment of many small sensor nodes over a large area of the manipulator surface to provide maximum sensor coverage. The ASIC design also provides a communication interface to support sensor commands from and sensor data transmission to a distributed processing system which allows modular implementation and operation of the sensor system. MSI is a commercial small business specializing in proximity sensing systems based upon infrared and acoustic sensors.

    2018-02-16

    This review discusses the electronic properties and the prospective research directions of superconductor-graphene heterostructures. The basic electronic properties of graphene are introduced to highlight the unique possibility of combining two seemingly unrelated physics, superconductivity and relativity. We then focus on graphene-based Josephson junctions, one of the most versatile superconducting quantum devices. The various theoretical methods that have been developed to describe graphene Josephson junctions are examined, together with their advantages and limitations, followed by a discussion on the advances in device fabrication and the relevant length scales. The phase-sensitive properties and phase-particle dynamics of graphene Josephson junctions are examined to provide an understanding of the underlying mechanisms of Josephson coupling via graphene. Thereafter, microscopic transport of correlated quasiparticles produced by Andreev reflections at superconducting interfaces and their phase-coherent behaviors are discussed. Quantum phase transitions studied with graphene as an electrostatically tunable two-dimensional platform are reviewed. The interplay between proximity-induced superconductivity and the quantum-Hall phase is discussed as a possible route to study topological superconductivity and non-Abelian physics. Finally, a brief summary on the prospective future research directions is given. © 2018 IOP Publishing Ltd.

    This study evaluates the extent to which an individual's stated altruistic sentiments can be influenced by context-most importantly, by the age and social proximity of the other person and by the nature of what is being sacrificed. We measure willingness to sacrifice own health for another person's health and willingness to sacrifice own wealth for another person's wealth. To evaluate these sentiments, two surveys were administered to representative samples of Americans which contained hypothetical scenarios with context randomly assigned; the first survey posed a dictator game question and the second survey was designed to elicit marginal rates of substitution between own and other's health/wealth. As expected, we find less altruism towards those who are more socially distant (e.g., strangers relative to family). We find individuals are more health altruistic towards young children and more wealth altruistic towards adults, and health altruism tends to be lowest for survey respondents near retirement age. We find no relationship between levels of altruism and the distance between the respondent's state of birth and state of current residence. These findings improve society's understanding of situational altruism and kinship and reciprocity as motivations for altruism, and they have practical implications concerning the economic valuation of human lives used to guide public policy-making.

    The purpose of this study was to evaluate the effectiveness and complications of the locking proximal humerus plate to treat proximal humerus fractures. A retrospective clinical trial. Department of Orthopaedics, Tianjin Medical University General Hospital. Sixty-eight consecutive patients with three- or four-part fractures of the proximal humerus were treated with locking proximal humerus plates. The deltopectoral anterolateral acromial approach was used to the proximal humerus; open reduction and locking proximal humerus plate were applied. Constant Score was used to measure the shoulder functional recovery, and Visual Analog Scale (VAS) was used to measure subjective evaluation of pain. The radiology was observed. After average 26.7 months, the average Constant Score was 72.6 ± 13.2 points and the average VAS was 1.2 ± 0.8 points. All the complications such as screw perforation into the glenohumeral joint, screws loosening, soft tissue infections, avascular necrosis and delayed union occurred in eight cases (11.8 %). The effectiveness of the locking proximal humerus plate was similar to other published literatures on treating fractures of the proximal humerus; however, a lower complications rate in short follow-up time was observed in this study. It may potentially provide a favorable option for treating three- or four-part fractures of the proximal humerus. Dealing with each particular fracture pattern, surgeons should have a decision of appropriate way to internal fixation.

  2. Queensland general practitioners' applications of the "mature minor" principle: the role of patient age and gender.

    Teoludzka, Anna; Bartholomew, Terence P

    2010-12-01

    Most Australian jurisdictions do not have legislation that stipulates an age by which a minor can make their own medical treatment decisions. Instead, they rely on Gillick v West Norfolk and Wisbech Area Health Authority [1986] AC 112, an English common law decision that recommends individual assessments of "maturity". This study explores how medical practitioners in the State of Queensland understand and apply this legal authority when faced with a young person wishing to make a contentious medical treatment decision. Almost 200 doctors made decisions about a hypothetical patient's competence and confidentiality, and detailed their reasoning in an open-ended format. The data indicate that the vagaries of existing legal criteria allow for a range of philosophical perspectives and idiosyncratic heuristics to play a role in assessment practices, and that particular combinations of patient age and gender made these cognitive shortcuts more likely to occur. A notable proportion of such processes are not consistent with legal guidelines, and this has implications for general practitioners' vulnerability to litigation as well as young patients' treatment trajectories.

  3. Households Willingness to Pay for the Emissions Reduction Policy, Queensland, Australia

    2015-09-01

    Full Text Available This study examines households’ willingness to support the emissions reduction policy and their perceptions of climate change using an Internet survey of more than 1,000 households in Queensland, Australia. Respondents were asked for their willingness to pay (WTP to support the emissions reduction target proposed by the Australian Government by paying extra on their electricity bills. The results can be summarized in four key findings. First, respondents’ WTP to support the emissions reduction target is higher if they perceive that climate change will result in high loss of biodiversity. Second, respondents were willing to support a higher emissions target than proposed by the Australian Government. Third, there is a correlation between respondents WTP to support the emissions reduction and their beliefs about climate change, its effect on standards of living, the environment, and future generations. Fourth, as the data show a high rate of zero responses, common for the contingent valuation method (CVM used in the survey, the zero bids were further investigated using the non-parametric Turnbull model and the more recent spike model. The results showed that although there is some support for the emissions reduction policy, it is not sufficient for the policy to be successful.

    2013-07-01

    Studies linking resource acquisition and trait expression have traditionally treated nutritional resources as a single currency, but recent research has shown that trait expression can depend as much on diet quality (nutrient composition) as on diet quantity (calories). Here, we investigate the role of nutrient composition and diet concentration on activity levels of adult Queensland fruit flies (Bactrocera tryoni Froggatt: Tephritidae). Male and female flies were fed diets that varied in the proportion of protein and carbohydrate as well as total amounts of protein and carbohydrate. Daily activity levels were then quantified using locomotor activity monitors during both light and dark phases. During the light phase, both sexes increased the proportion of time spent active and their rate of activity as diets became more carbohydrate-rich and concentrated. In contrast, during the dark phase, nutrient composition and concentration had no effect on the proportion of time spent active for either sex, although when active during the dark phase, activity rates were higher for flies fed more carbohydrate-rich and concentrated diets. Overall, nutritional composition of the diet affected activity levels to a greater extent than the total energetic content of the diet. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Yeast hydrolysate supplements promote maturation of many tephritid flies targeted for control using the sterile insect technique (SIT), including Queensland fruit fly (Bactrocera tryoni; 'Q-fly'). Recently, application of the juvenile hormone analogue methoprene has been demonstrated to further promote maturation in some species. We here investigate the separate and combined effects of yeast hydrolysate and methoprene treatment on sexual maturation of sterile male and female Q-flies. Two methods of applying methoprene solution were used; topical application to adults and dipping of pupae. Consistent with previous studies, access to yeast hydrolysate greatly increased maturation of both male and female Q-flies. Maturation was further promoted by methoprene treatment, with similar effects evident for males and females and for both application methods. For flies provided access to yeast hydrolysate supplements, methoprene treatment advanced maturation by approximately 2days. No effects of diet or methoprene treatment were found on timing of copulation or copula duration. Countering the positive effects on sexual maturation, dipping of pupae in methoprene/acetone solution did diminish emergence rates and flight ability indices, and increased rates of wing deformity. Promising results of the present study encourage further investigation of treatment methods that maximise maturation while minimising detrimental effects on other aspects of fly quality.

    Copula duration and sperm storage patterns can directly or indirectly affect fitness of male and female insects. Although both sexes have an interest in the outcome, research has tended to focus on males. To investigate female influences, we compared copula duration and sperm storage of Queensland fruit fly females that were intact, or had been incapacitated through decapitation or abdomen isolation. We found that copulations were far longer when females had been incapacitated, indicating that constraints imposed on copula duration by intact females had been relaxed. Repeatability of copula duration for males was very low regardless of female treatment, and this is also consistent with strong female influence. Number of sperm in the spermathecae was not influenced by female treatment, suggesting that female abdominal ganglia control the transport of sperm to these long-term storage organs. However, more sperm were found in the ventral receptacles of incapacitated females compared to intact females. Overall, results implicate cephalic ganglia in regulation of copula duration and short-term sperm storage in the ventral receptacle and abdominal ganglia in regulation of long-term sperm storage in the spermathecae.

    The trade-off between lifespan and reproduction is commonly explained by differential allocation of limited resources. Recent research has shown that the ratio of protein to carbohydrate (P : C) of a fly's diet mediates the lifespan-reproduction trade-off, with higher P : C diets increasing egg production but decreasing lifespan. To test whether this P : C effect is because of changing allocation strategies (Y-model hypothesis) or detrimental effects of protein ingestion on lifespan (lethal protein hypothesis), we measured lifespan and egg production in Queensland fruit flies varying in reproductive status (mated, virgin and sterilized females, virgin males) that were fed one of 18 diets varying in protein and carbohydrate amounts. The Y-model predicts that for sterilized females and for males, which require little protein for reproduction, there will be no effect of P : C ratio on lifespan; the lethal protein hypothesis predicts that the effect of P : C ratio should be similar in all groups. In support of the lethal protein hypothesis, and counter to the Y-model, the P : C ratio of the ingested diets had similar effects for all groups. We conclude that the trade-off between lifespan and reproduction is mediated by the detrimental side-effects of protein ingestion on lifespan.

    Queensland fruit fly, Bactrocera tryoni (Q-fly), is a major pest of horticultural crops in eastern Australia. Lures that attract male Q-fly are important for detection of incursions and outbreaks, monitoring of populations, and control by mass trapping and male annihilation. Cuelure, an analog of naturally occurring raspberry ketone, is the standard Q-fly lure, but it has limited efficacy compared with lures that are available for some other fruit flies such as methyl eugenol for B. dorsalis. Melolure is a more recently developed raspberry ketone analog that has shown better attraction than cuelure in some field studies but not in others. A novel fluorinated analog of raspberry ketone, raspberry ketone trifluoroacetate (RKTA), has been developed as a potential improvement on cuelure and melolure. RKTA placed on laboratory cages containing 2-week-old Q-flies elicited strong behavioral responses from males. Quantification of Q-fly responses in these cages, using digital images to estimate numbers of flies aggregated near different lures, showed RKTA attracted and arrested significantly more flies than did cuelure or melolure. RKTA shows good potential as a new lure for improved surveillance and control of Q-fly.

    Full Text Available This review draws together available information on the biology, methods for study, and culturing of hymenopteran parasitoids of the Queensland fruit fly, Bactrocera tryoni, and assesses prospects for improving biological control of this serious pest. Augmentative release of the native and naturalised Australian parasitoids, especially the braconid Diachasmimorpha tryoni, may result in better management of B. tryoni in some parts of Australia. Mass releases are an especially attractive option for areas of inland eastern Australia around the Fruit Fly Exclusion Zone that produces B. tryoni-free fruits for export. Diachasmimorpha tryoni has been successful in other locations such as Hawaii for the biological control of other fruit fly species. Biological control could contribute to local eradication of isolated outbreaks and more general suppression and/or eradication of the B. tryoni population in endemic areas. Combining biological control with the use of sterile insect technique offers scope for synergy because the former is most effective at high pest densities and the latter most economical when the pest becomes scarce. Recommendations are made on methods for culturing and study of four B. tryoni parasitoids present in Australia along with research priorities for optimising augmentative biological control of B. tryoni.

    Raspberry ketone (RK) is highly attractive to sexually mature, but not immature, males of many Bactrocera species, including Queensland fruit fly ('Qfly', Bactrocera tryoni), and acts as a metabolic enhancer in a wide diversity of animals. We considered the possibility that, as a metabolic enhancer, RK in adult diet might accelerate sexual maturation of male Qflies. Recently emerged adult Qfly males (0-24 h old) were exposed to RK-treated food for 48 h and were then provided only sugar and water. Four doses of RK (1.25, 2.5, 3.75 and 5%) along with control (0%) were tested with two types of food: sugar alone and sugar mixed with yeast hydrolysate (3:1). For flies tested when 4-10 days old all RK doses increased mating probability of flies fed sugar mixed with yeast hydrolysate but did not show any effect on mating probability of flies fed only sugar. No effects of RK were found for flies tested when 10-30 days old for either diet group. There was no evidence that RK affected longevity at any of the doses tested. Feeding of RK together with yeast hydrolysate to immature Qfly increases mating propensity at young ages and accordingly shows significant potential as a pre-release supplement that might increase the proportion of released flies that attain sexual maturation in Sterile Insect Technique programmes. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Full Text Available In this case study, I examine the quality of decision-making under conditions of rapidly evolving urban water crises, and the adaptive policy challenges of building regional resilience in response to both drought and flood. Like other regions of Australia, Southeast Queensland has been subject to substantial cycles of drought and flood. I draw on resilience literature concerning sustainability, together with governance literature on policy change, to explain the changing awareness of urban water crises and the strategic options available for addressing these crises in this case study. The problem of resilience thinking opens up a number of important questions about the efficacy and adaptability of the policy system. The case provides insights into the interplay between the ways in which problems are framed, the knowledge bases required for planning and decision-making, the collaborative governance processes required for managing complex and rapidly evolving issues, and the overall capacity for policy learning over time. Regional resilience was proclaimed as a policy goal by government, but the practices remained largely anchored in traditional technical frameworks. Centralized investment decisions and governance restructures provoked conflict between levels of government, undermining the capacity of stakeholders to create more consensual approaches to problem-solving and limiting the collective learning that could have emerged.

A cross-sectional survey conducted during 1998-2000. Twenty-six rural communities in north Queensland, Australia. A total of 2524 Indigenous people aged 15 years and over was included in the study. Self-reported fruit and vegetable intake, tobacco smoking, alcohol intake and physical activity were recorded. RCF was measured using the Bayer Advia Centaur automated immunoassay system. The association between low RCF (RCFdiabetes and dyslipidaemia. The prevalence of RCF deficiency was higher in Aboriginal participants compared with Torres Strait Islanders (25.6 % v. 14.8 %, P Indigenous Australians, especially women of childbearing age, had high prevalence of low RCF. Smoking was associated with insufficient folate independent of fruit and vegetable intake and alcohol consumption in the Aboriginal population. This population with an already higher risk of obesity and higher rate of tobacco smoking should be targeted to improve nutrition status to prevent ill health such as diabetes and CVD.

    In the summer of 1999/2000, an epizootic occurred in cultured juvenile redclaw crayfish Cherax quadricarinatus on one commercial crayfish farm in northern Queensland, Australia. Mortalities occurred over 4 wk, with up to 96% cumulative mortalities in 2 earthen ponds stocked with juveniles. The crayfish were weak, anorexic and lethargic. A transmission trial was conducted, using filtered, cell-free extract prepared from infected crayfish as inoculum. The disease was reproduced, with on-going mortalities occurring in inoculated crayfish over 55 d. Experimentally inoculated crayfish showed gross signs of malaise, anorexia and disorientation before dying. Two types of intranuclear inclusion bodies (INIBs) were seen in tissues of endodermal, ectodermal and mesodermal origin by light microscopy with haematoxylin and eosin (H&E) stained sections. 'Early'-stage INIBs were eosinophilic, rounded and located centrally within slightly enlarged nuclei while 'late'-stage INIBs were well-rounded and deeply basophilic. The gills, cuticular epithelium and epithelial cells of the foregut, midgut and hindgut were the most heavily infected tissues. By transmission electron microscopy, virions with an average diameter of 19.5 nm were seen within electron-dense granular inclusion bodies within enlarged nuclei of both naturally and experimentally infected crayfish. The size of the virions and cytopathology are consistent with characteristics of viruses in the Family Parvoviridae. This is the first reported case of mass mortality caused by a parvo-like virus infection in C. quadricarinatus.

    Full Text Available A lack of published information documenting problems with the microchip data for the reclaiming of stray animals entering Australian shelters limits improvement of the current microchipping system. A retrospective study analysing admission data for stray, adult dogs (n = 7258 and cats (n = 6950 entering the Royal Society for the Prevention of Cruelty to Animals (RSPCA Queensland between January 2012 and December 2013 was undertaken to determine the character and frequency of microchip data problems and their impact on outcome for the animal. Only 28% of dogs and 9% of cats were microchipped, and a substantial proportion (37% had problems with their data, including being registered to a previous owner or organisation (47%, all phone numbers incorrect/disconnected (29%, and the microchip not registered (14%. A higher proportion of owners could be contacted when the microchip had no problems, compared to those with problems (dogs, 93% vs. 70%; cats, 75% vs. 41%. The proportion of animals reclaimed declined significantly between microchipped animals with no data problems, microchipped animals with data problems and non-microchipped animals—87%, 69%, and 37%, respectively, for dogs and 61%, 33%, and 5%, respectively, for cats. Strategies are needed to increase the accuracy of microchip data to facilitate the reclaiming of stray dogs and cats.

    2003-01-01

    Full Text Available Governments and other policy makers are concerned with the gap in home Internet usage between people from metropolitan and rural areas. A survey conducted in Central Queensland, Australia examined differences in home Internet usage patterns between young and old, male and female, people in urban and rural areas, married and unmarried, well-educated and less educated, rich and poor, and employed and unemployed and found significant differences. These results highlight areas for further research and provide a basis for government agencies and industries to consider these associations in future policy formulation for regional development using ICT. The research suggested that further research should be conducted to monitor consuming behaviors of the youngest age group in Internet use for entertainment and information search in order to detect possible Internet overuse or addiction. In addition, further research should be conducted to find out what people search for on the Internet, and if for employment opportunities, financial incentives are suggested for the unemployed people.

    The Central Queensland University (CQU) has championed a self-contained concrete lined evapotranspiration channel. Any non-transpired effluent returns to a holding tank and is recirculated through the evapotranspiration channel until it is used. This paper examines the results from the Rockhampton trial site. Nutrient ions in the effluent were quantified over time and found not to accumulate in solution. Microbial analysis of the treated effluent was performed and was found to be within the ranges required by the relevant legislative codes. Citrus fruit grown in the evapotranspiration channel were sampled and no elevated levels of faecal coliforms were recorded. Macronutrients and micronutrients of the soil in the channels were measured over a 5-year period. No toxic accumulations or nutrient deficiencies in the soil occurred. Levels of salinity and sodicity in the evapotranspiration channel soil were quantified. Salinity rose slightly, as did sodium. Concentrations of salts and sodium did not reach unsustainable levels. The aim of the trial was to develop an on-site treatment and reuse system that is sustainable and protects public and environmental health.

    The purpose of the study was to inform policy for reform in nursing. A survey mailed to members of the Queensland Nurses' Union four times between 2001 and 2010 elicited views on their employment and working conditions, professional development and career opportunities. Results across years and sectors of nursing consistently showed dissatisfaction in many aspects of employment, particularly by nurses working in aged care. However, views on staffing numbers, skill mix, workload, work stress, pay and staff morale all showed significant improvements over the decade. For example in 2001, 48.8% of nurses believed that their pay was poor, whereas in 2010, this had reduced to 35.2%. Furthermore, there was a significant rise throughout the decade in the opinion of the value of nursing as a good career. In light of the need to address nurse workforce shortages, the trends are encouraging; however, more improvements are required in order to support recruitment and retention. © 2013 Wiley Publishing Asia Pty Ltd.

    Full Text Available Abstract Background Suicide in mentally ill subjects, like schizophrenics, remains unbearably frequent in Australia and elsewhere. Since these patients are known to constitute a high-risk group, suicide in them should be amongst the most preventable ones. The objective of this study is to investigate the frequency of suicide communication in subjects with reported history of schizophrenia who completed suicide. Method The Queensland Suicide Register (QSR was utilised to identify suicide cases. Frequency of suicide communication was examined in subjects with schizophrenia, and compared with persons with other psychiatric conditions and with subjects with no reported diagnosis. Socio-demographic variables, history of suicidal behaviour, pharmacological treatment and mental health service utilisation were also compared among the three groups. Results and discussion Subjects with a reported diagnosis of schizophrenia comprised 7.2% (n = 135 of the 1,863 suicides included in this study. Subjects with schizophrenia and those with other psychiatric disorders communicated their suicide intent more frequently than those with no psychiatric diagnosis, and persons with schizophrenia communicated their intent more than those with other psychiatric diagnoses. Seventy one per cent of schizophrenia subjects had contact with a mental health professional within the three months prior to suicide. Conclusion The fact that subjects with schizophrenia had the highest prevalence of suicide intent communication could offer concrete opportunities for suicide prevention.

    Suicide rates among Indigenous Australian children are higher than for other Australian children. The current study aimed to identify factors associated with Indigenous child suicide when compared to other Australian children. Using the Queensland Suicide Register, suicides in Indigenous children (10-14 years) and other Australian children in the same age band were compared. Between 2000 and 2010, 45 child suicides were recorded: 21 of Indigenous children and 24 of other Australian children. This corresponded to a suicide rate of 10.15 suicides per 100,000 for Indigenous children - 12.63 times higher than the suicide rate for other Australian children (0.80 per 100,000). Hanging was the predominant method used by all children. Indigenous children were significantly more likely to suicide outside the home, to be living outside the parental home at time of death, and be living in remote or very remote areas. Indigenous children were found to consume alcohol more frequently before suicide, compared to other Australian children. Current and past treatments of psychiatric disorders were significantly less common among Indigenous children compared to other Australian children. Western conceptualisation of mental illness may not adequately embody Indigenous people's holistic perspective regarding mental health. Further development of culturally appropriate suicide prevention activities for Aboriginal and Torres Strait Islander children is required. © 2014 Public Health Association of Australia.

    A lack of published information documenting problems with the microchip data for the reclaiming of stray animals entering Australian shelters limits improvement of the current microchipping system. A retrospective study analysing admission data for stray, adult dogs (n = 7258) and cats (n = 6950) entering the Royal Society for the Prevention of Cruelty to Animals (RSPCA) Queensland between January 2012 and December 2013 was undertaken to determine the character and frequency of microchip data problems and their impact on outcome for the animal. Only 28% of dogs and 9% of cats were microchipped, and a substantial proportion (37%) had problems with their data, including being registered to a previous owner or organisation (47%), all phone numbers incorrect/disconnected (29%), and the microchip not registered (14%). A higher proportion of owners could be contacted when the microchip had no problems, compared to those with problems (dogs, 93% vs. 70%; cats, 75% vs. 41%). The proportion of animals reclaimed declined significantly between microchipped animals with no data problems, microchipped animals with data problems and non-microchipped animals-87%, 69%, and 37%, respectively, for dogs and 61%, 33%, and 5%, respectively, for cats. Strategies are needed to increase the accuracy of microchip data to facilitate the reclaiming of stray dogs and cats.

  2. New U/Th ages for Pleistocene megafauna deposits of southeastern Queensland, Australia

    Arguments over the extinction of Pleistocene megafauna have become particularly polarised in recent years. Causes for the extinctions are widely debated with climate change, human hunting and/or habitat modification, or a combination of those factors, being the dominant hypotheses. However, a lack of a spatially constrained chronology for many megafauna renders most hypotheses difficult to test. Here, we present several new U/Th dates for a series of previously undated, megafauna-bearing localities from southeastern Queensland, Australia. The sites were previously used to argue for or against various megafauna extinction hypotheses, and are the type localities for two now-extinct Pleistocene marsupials (including the giant koala, Phascolarctos stirtoni). The new dating allows the deposits to be placed in a spatially- and temporally constrained context relevant to the understanding of Australian megafaunal extinctions. The results indicate that The Joint (Texas Caves) megafaunal assemblage is middle Pleistocene or older (>292 ky); the Cement Mills (Gore) megafaunal assemblage is late Pleistocene or older (>53 ky); and the Russenden Cave Bone Chamber (Texas Caves) megafaunal assemblage is late Pleistocene (˜55 ky). Importantly, the new results broadly show that the sites date prior to the hypothesised megafaunal extinction 'window' (i.e., ˜30-50 ky), and therefore, cannot be used to argue exclusively for or against human/climate change extinction models, without first exploring their palaeoecological significance on wider temporal and spatial scales.

    Perkinsus sp. protists were found infecting Anadara trapezia mud ark cockles at 6 sites in Moreton Bay, Queensland, Australia, at prevalences of 4 to 100% during 2011 as determined by surveys using Ray's fluid thioglycollate medium. Perkinsus sp. lesions were found among gill and visceral connective tissues in histological samples from several cockles, where basophilic, eccentrically vacuolated Perkinsus sp. signet ring trophozoites and proliferating, Perkinsus sp. schizont cells were documented. Two Perkinsus sp. isolates were propagated in vitro during August 2013 from gill tissues of a single infected A. trapezia cockle from Wynnum in Moreton Bay. DNA from those isolate cells amplified universally by a Perkinsus genus-specific PCR assay, and rDNA-internal transcribed spacer sequences respectively grouped them with P. olseni and P. chesapeaki in phylogenetic analyses. This is the first report of P. chesapeaki in Australia, and the first report of a P. chesapeaki in vitro isolate from an Australian mollusc host. Although P. olseni was originally described in 1981 as a pathogen of abalone in South Australia, and has subsequently been identified as a prevalent pathogen of numerous other molluscs worldwide, this is also the first report of a P. olseni-like in vitro isolate from an Australian mollusc host.

    Full Text Available This study aimed to understand peri-urban areas consumers perception of organic food and the importance of organic certification in customers decisions for obtaining insights into their consumption of organic food. Data was collected through a questionnaire survey at two main supermarkets in Gatton town Queensland Australia. This research showed that 42.4 of consumers purchase organic food at least once per month. Health protection was found the most important reason for Australian peri-urban consumers to purchase organic food. Most of them 89.5 were interested in organic food but only around 59 of consumers were confident with the claimed benefits of the food and 42 trust in the organic certification. The more consumers are interested in trust and are confident with the claimed benefits the more likely will they purchase organic food. In addition organic labels and certification turned out to be important for the consumers when shopping organic food. This research was the first study to investigate the consumers perception of organic food in an Australian peri-urban area especially relationships between the frequency of purchase and consumers level of knowledge and their behaviors toward organic food. Both practical and theoretical contributions of this study are also discussed.

    Molecules in male seminal fluid transferred to female insects during mating can have potent effects on their subsequent sexual and reproductive behaviour. Like many other tephritids, female Queensland fruit flies (Bactrocera tryoni) typically have diminished sexual receptivity after their first mating. Also, copulations of females that do remate tend to be shorter than those of virgins. We here find that virgin females injected with small doses (0.1, 0.2 or 0.5 male equivalents) of extracts from the male reproductive tract accessory tissues, which consist of male accessory glands, ejaculatory apodeme and ejaculatory duct (AG/EA/ED), have diminished receptivity and short copula duration very similar to naturally mated females. In contrast, virgin females injected with saline or with high doses of AG/EA/ED (1 or 2 male equivalents) that likely exceed the range of natural variation retain the higher levels of sexual receptivity and longer copulations of un-injected virgins. We conclude that reduced sexual receptivity and shorter copulations of mated female Q-flies are mediated by products in the male seminal fluid derived from the male reproductive tract accessory tissues.

    Data on the erodibility of overburden spoils resulting from open-cut coal mining are limited. These data are required to derive parameters for erosion prediction models which can be used in the design of re-formed landscapes after mining. In this study, laboratory rainfall simulation data were used to derive CREAMS (Chemicals, Runoff and Erosion from Agricultural Management Systems) interfill erodibility parameters K and n{sub bov} for Central Queensland coal mine overburden spoils. For the spoils studied, K values ranged from 0.0111 to 0.1398 Mg ha h/(ha MJ mm) and n{sub bov} values ranged from 0.0004 to 0.0081. Sediment yield was transport controlled. Results for 1 spoil, South Blackwater Terang, showed that total soil loss increased linearly with slope, and both K and n{sub bov} varied non-linearly with slope. If a constant set of K and n{sub bov} values is used in modelling, CREAMS over-predicts spoil loss for slopes greater than that for which the parameter values were determined, and under-predicts spoil loss for slopes less than that for which the parameter values were determined.

    Cigarette smoking has been associated with increased risk of progressive multiple sclerosis (MS). The effect of smoking status on risk and timing of disease progression in patients with MS in Queensland, Australia has not been established. A clinical cohort of 646 cases (531 females, 115 males) were followed from first clinic attendance to onset of clinically determined progressive disease. Progression risk was analysed with gender, age, age of onset, exposure to disease modifying therapy, and smoking status as covariates in a Cox proportional hazards analysis. There were significantly higher risks of secondary progressive disease in males (Hazard Ratio, HR 1.83, 95% CI: 1.3-2.7) and in ever smokers (HR 1.4, 95% CI: 1.0-2.0). Progressive disease occurred approximately 4years earlier in ever smokers. Smoking did not affect age of onset of primary progressive disease. Cigarette smoking was associated with earlier onset of progressive disease in this large clinical cohort. For patients with relapsing-remitting disease, smoking cessation should be encouraged.

    A new extended pollen and charcoal record is presented from Lake Euramoo, Wet Tropics World Heritage rainforest of northeast Queensland, Australia. The 8.4-m sediment core taken from the center of Lake Euramoo incorporates a complete record of vegetation change and fire history spanning the period from 23,000 cal yr B.P. to present. The pollen record is divided into five significant zones; 23,000-16,800 cal yr B.P., dry sclerophyll woodland; 16,800-8600 cal yr B.P., wet sclerophyll woodland with marginal rainforest in protected pockets; 8600-5000 cal yr B.P., warm temperate rainforest; 5000-70 cal yr B.P., dry subtropical rainforest; 70 cal yr B.P.-AD 1999, degraded dry subtropical rainforest with increasing influence of invasive species and fire. The process of rainforest development appears to be at least partly controlled by orbital forcing (precession), though more local environmental variables and human activity are also significant factors. This new record provides the opportunity to explore the relationship between fire, drought and rainforest dynamics in a significant World Heritage rainforest region.

    The aim of this study is to examine cost-effectiveness of fluoridation of drinking water supplies for Brisbane and South East Queensland. The benefits conveyed are expressed in reduced costs of dental treatment and years of life with dental caries as a disability. The analysis utilises a developed life table modelling initial cohort of 36,322 newborns, which when applied to the target population equals to 181,925 persons in the age group 2-100 years, 338,617 persons in the age group 7-100 years and 390,524 persons in the age group 12-100 years respectively. The analysis was conducted using a real discount rate of 3%. Sensitivity analyses investigated the effects of varying the parameters such as: discount rate, costs of dental treatment and costs of fluoridation plant. Uncertainty analysis was also conducted on costs and the measure of ratio of decayed, missing, filled teeth surfaces in deciduous dentition between the cities of Brisbane (non-fluoridated) and Townsville (fluoridated). If fluoridation was implemented there would be a total saving of $10,437.43 (95% CI 6,406.50- 14,035.35) disability-adjusted life years (DALYs) and AU$ 665,686,529 (95% CI -$973,573,625- $381,322,176). This result is both desirable and dominant as more DALYs are saved along with significant cost savings. Fluoridation remains still a very cost-effective measure for reducing dental decay.

    Full Text Available Phytoliths are micrometric particles of amorphous silica that form inside or between the cells of higher plant tissues throughout the life of a plant. With plant decay, phytoliths are either incorporated into soils or exported to sediments via regional watersheds. Phytolith morphological assemblages are increasingly used as proxy of grassland diversity and tree cover density in inter-tropical areas. Here, we investigate whether, along altitudinal gradients in northeast Queensland (Australia, changes in the δ18O signature of soil top phytolith assemblages reflect changes in mean annual temperature (MAT and in the oxygen isotopic composition of precipitation (δ18Oprecipitation, as predicted by equilibrium temperature coefficients previously published for silica. Oxygen isotopic analyses were performed on 16 phytolith samples, after controlled isotopic exchange (CIE, using the IR Laser-Heating Fluorination Technique. Long-term mean annual precipitation (MAP and MAT values at the sampled sites were calculated by the ANUCLIM software. δ18Oprecipitation estimates were calculated using the Bowen and Wilkinson (2002 model, slightly modified. An empirical temperature-dependant relationship was obtained: δ18Owood phytolith-precipitation (‰ vs. VSMOW = −0.4 (±0.2 t (°C + 46 (±3 (R2 = 0.4, p < 0.05; n = 12. Despite the various unknowns introduced when estimating δ18Oprecipitation values and the large uncertainties on δ18Owood phytolith values, the temperature coefficient (−0.4 ± 0.2‰ °C−1 is in the range of values previously obtained for natural quartz, fresh and sedimentary diatoms and harvested grass phytoliths (from −0.2 to −0.5‰ °C−1. The consistency supports the reliability of δ18Owood phytolith signatures for recording

  11. Locking plate fixation for proximal humerus fractures.

    2012-02-01

    Locking plates are increasingly used to surgically treat proximal humerus fractures. Knowledge of the bone quality of the proximal humerus is important. Studies have shown the medial and dorsal aspects of the proximal humeral head to have the highest bone strength, and this should be exploited by fixation techniques, particularly in elderly patients with osteoporosis. The goals of surgery for proximal humeral fractures should involve minimal soft tissue dissection and achieve anatomic reduction of the head complex with sufficient stability to allow for early shoulder mobilization. This article reviews various treatment options, in particular locking plate fixation. Locking plate fixation is associated with a high complication rate, such as avascular necrosis (7.9%), screw cutout (11.6%), and revision surgery (13.7%). These complications are frequently due to the varus deformation of the humeral head. Strategic screw placement in the humeral head would minimize the possibility of loss of fracture reduction and potential hardware complications. Locking plate fixation is a good surgical option for the management of proximal humerus fractures. Complications can be avoided by using better bone stock and by careful screw placement in the humeral head.

    Nurses represent the largest occupational group of health care professionals in Australia. The ratio of nurses to population is relatively consistent, unlike other health care professional groups (including medical doctors and allied health staff) whose numbers decline as population density and distance from metropolitan areas increases. Nurses working in areas where other health care professionals are limited or absent have expanded scopes of practice with their work being more generalist than specialist. The role of nurses in remote and isolated areas of Queensland, Australia was the focus of a commissioned multi-case research project. Findings reported in this paper relate to the position of registered nurses as part of an interprofessional team. These findings indicated that, in some instances, local health care teams were limited to a single nurse and Indigenous health care worker/s, while in others the teams were more diverse. In all cases collegial support was available either locally or via telecommunication technology. Understanding the role of each team member, having useful strategies to enhance communication and work collaboratively were identified as essential criteria for "good practice".

    This study aimed to assess the screening performance of the quantitative light-induced fluorescence (QLF) technology to detect proximal caries using both fluorescence loss and red fluorescence in a clinical situation. Moreover, a new simplified QLF score for the proximal caries (QS-Proximal) is proposed and its validity for detecting proximal caries was evaluated as well. This clinical study included 280 proximal surfaces, which were assessed by visual-tactile and radiographic examinations and scored by each scoring system according to lesion severity. The occlusal QLF images were analysed in two different ways: (1) a quantitative analysis producing fluorescence loss (ΔF) and red fluorescence (ΔR) parameters; and (2) a new QLF scoring index. For both quantitative parameters and QS-Proximal, the sensitivity, specificity, and area under the receiver operating characteristic curve (AUROC) were calculated as a function of the radiographic scoring index at the enamel and dentine caries levels. Both ΔF and ΔR showed excellent AUROC values at the dentine caries level (ΔF=0.860, ΔR=0.902) whereas a relatively lower value was observed at the enamel caries level (ΔF=0.655, ΔR=0.686). The QS-Proximal also showed excellent AUROC ranged from 0.826 to 0.864 for detecting proximal caries at the dentine level. The QS-Proximal, which represents fluorescence changes, showed excellent performance in detecting proximal caries using the radiographic score as the gold standard. Copyright © 2017 Elsevier B.V.

    In this thesis, we present ProxiSART, a flexible proximal framework for robust 3D cone beam tomographic reconstruction based on the Simultaneous Algebraic Reconstruction Technique (SART). We derive the proximal operator for the SART algorithm and use it for minimizing the data term in a proximal algorithm. We show the flexibility of the framework by plugging in different powerful regularizers, and show its robustness in achieving better reconstruction results in the presence of noise and using fewer projections. We compare our framework to state-of-the-art methods and existing popular software tomography reconstruction packages, on both synthetic and real datasets, and show superior reconstruction quality, especially from noisy data and a small number of projections.

    Human behaviors exhibit ubiquitous correlations in many aspects, such as individual and collective levels, temporal and spatial dimensions, content, social and geographical layers. With rich Internet data of online behaviors becoming available, it attracts academic interests to explore human mobility similarity from the perspective of social network proximity. Existent analysis shows a strong correlation between online social proximity and offline mobility similarity, namely, mobile records between friends are significantly more similar than between strangers, and those between friends with common neighbors are even more similar. We argue the importance of the number and diversity of common friends, with a counter intuitive finding that the number of common friends has no positive impact on mobility similarity while the diversity plays a key role, disagreeing with previous studies. Our analysis provides a novel view for better understanding the coupling between human online and offline behaviors, and will help model and predict human behaviors based on social proximity.

    2016-01-01

    Children with ambiguous genitalia due to different chromosome or gonadal sex are a particular challenge concerning the diagnostic and therapeutic implications. Proximal hypospadias patients with normal gonadal development should be distinguished from children with DSD (disorders of sex development) to guarantee normal gender identity and the best possible surgical therapy. This paper focuses on the terminology, embryology, and pathophysiology of the different manifestations of DSD. The state of knowledge about this disease pattern with particular emphasis on proximal hypospadias based on national and international scientific discussions is presented. The different clinical pictures as well as therapeutic options of DSD with a special focus on recent literature and giving particular attention to patients with proximal hypospadias are presented. Because of the complexity of patients suffering from disorders of sex development an interdisciplinary DSD healthcare team including a paediatric endocrinologist as well as paediatric urologist should be provided. These specialists enable an accurate diagnosis in severe hypospadias patients without reference to DSD diseases patterns.

    Proximal sensing as the near field counterpart of remote sensing offers a broad variety of applications. Imaging spectroscopy in general and translational laboratory imaging spectroscopy in particular can be utilized for a variety of different research topics. Geoscientific applications require a precise pre-processing of hyperspectral data cubes to retrieve at-surface reflectance in order to conduct spectral feature-based comparison of unknown sample spectra to known library spectra. A new pre-processing chain called GeoMAP-Trans for at-surface reflectance retrieval is proposed here as an analogue to other algorithms published by the team of authors. It consists of a radiometric, a geometric and a spectral module. Each module consists of several processing steps that are described in detail. The processing chain was adapted to the broadly used HySPEX VNIR/SWIR imaging spectrometer system and tested using geological mineral samples. The performance was subjectively and objectively evaluated using standard artificial image quality metrics and comparative measurements of mineral and Lambertian diffuser standards with standard field and laboratory spectrometers. The proposed algorithm provides highly qualitative results, offers broad applicability through its generic design and might be the first one of its kind to be published. A high radiometric accuracy is achieved by the incorporation of the Reduction of Miscalibration Effects (ROME) framework. The geometric accuracy is higher than 1 μpixel. The critical spectral accuracy was relatively estimated by comparing spectra of standard field spectrometers to those from HySPEX for a Lambertian diffuser. The achieved spectral accuracy is better than 0.02% for the full spectrum and better than 98% for the absorption features. It was empirically shown that point and imaging spectrometers provide different results for non-Lambertian samples due to their different sensing principles, adjacency scattering impacts on the signal

    The oral health of rural Australians continues to lag behind that of those living in metropolitan areas. Research has shown that people living in rural areas are more likely to suffer from dental caries (decay), visit the dentist less often and have poorer access to oral health services. The purpose of the study was to examine hospitalisations for dental conditions and utilisation of public dental services in three rural communities in Queensland compared with the whole of Queensland. Aggregated hospitalisation data for dental conditions and counts of public outpatient service data were requested for residents of three rural communities in Queensland and for the whole of Queensland for the calendar year 2013. Hospitalisation rates per 1000 and risk ratios were calculated to examine the risk of hospitalisation for dental procedures for those living in the selected rural communities and the rest of Queensland. Data were grouped by gender, age and Indigenous status and comparisons made between Queensland and the rural communities. Outpatient service data were converted to percentage of all services delivered to allow comparisons between groups of different sizes. Population data were grouped into age cohorts and compared with the proportion of public oral health services delivered to each age cohort. Residents of the rural communities were twice as likely to be hospitalised and children aged 0-14 years living in the communities were three times more likely to be hospitalised for dental conditions compared to residents of the rest of Queensland. Outpatient oral service data showed that the proportion of services delivered to children aged up to 14 years living in the rural communities was less than the whole of Queensland. Interestingly, in one rural community where the public dental service was open to all, the distribution of public oral health services aligned with the age distribution of the population. The study showed that residents of these rural communities

    Instability of the proximal tibiofibular joint is a relatively uncommon condition when in isolation; however, instability of the proximal tibiofibular joint is far more frequent in those presenting with a severe multi-ligament injury of the knee. If this joint is left unstable, repair of a co-existent injury of the posterolateral corner may fail, regardless of the proficiency of the technique. We present two patients with disruption of the proximal tibiofibular joint, including the MRI appearance, who initially presented to our hospital for management of significant polytrauma, as well as multi-ligament injury of the ipsilateral knee.

    Although a great deal of research has tested the longitudinal effects of regularly practicing gratitude, much less attention has been paid to the emotional landscape directly following engagement in gratitude exercises. In three studies, we explored the array of discrete emotions people experience after being prompted to express or recall gratitude. In Studies 1 and 2, two different gratitude exercises produced not only greater feelings of gratitude relative to two positive emotion control conditions (i.e., recalling relief), but also higher levels of other socially relevant states like elevation, connectedness, and indebtedness. In a third study, conducted in both the U.S. and S. Korea, we compared a gratitude exercise to another positive emotion elicitation (i.e., recalling a kind act) and to a neutral task, and again found that the gratitude exercise prompted greater gratitude, elevation, indebtedness, and guilt, but no more embarrassment or shame, than the two comparison conditions. Additionally, in all three studies, emodiversity and cluster analyses revealed that gratitude exercises led to the simultaneous experience of both pleasant and unpleasant socially-relevant states. In sum, although it may seem obvious that gratitude exercises would evoke grateful, positive states, a meta-analysis of our three studies revealed that gratitude exercises actually elicit a mixed emotional experience-one that simultaneously leads individuals to feel uplifted and indebted.

    Sickel, Jamie L.

    This study sought to identify key experiences that impact the development of technological pedagogical content knowledge (TPACK) of preservice secondary sciences teachers at a medium-sized university in Queensland, Australia. TPACK is a conceptual framework of a body of knowledge that teachers draw upon to influence practice; it is a dynamic and emergent form of knowledge that informs the employment of technology for teaching specific subject matter. This study employed an embedded case study approach, including delivery of a TPACK survey instrument and analysis of participant interviews, to identify the context-specific experiences that promote the development of TPACK among twelve preservice secondary science teachers. The research addresses a specific need cited in the literature, identifying TPACK impact factors, and provides a novel way to visualize TPACK development through contextual experiences. A novel approach to visually representing context-specific experiences and their influence on teacher knowledge, self-efficacy, values and beliefs was employed. Three major findings are presented below: 1) the majority of preservice secondary science teachers were unable to define the constructs of learning and science; 2) a focus on motivation and interest paired with a disconnect between expressed and enacted pedagogical orientation lead to teacher-centered instruction augmented with superficial tactics aimed at generating interest; and 3) difficulty in integrating knowledge bases yielded lower TPACK self-efficacy, which has detrimental impacts on the instruction planned by pre-service teachers for their students. Findings are directly aligned with participants' prior experience, compared to the relevant literature, and utilized to identify implications for teacher preparation as well as recommendations for future research.

    Caloric restriction (CR) has been widely accepted as a mechanism explaining increased lifespan (LS) in organisms subjected to dietary restriction (DR), but recent studies investigating the role of nutrients have challenged the role of CR in extending longevity. Fuelling this debate is the difficulty in experimentally disentangling CR and nutrient effects due to compensatory feeding (CF) behaviour. We quantified CF by measuring the volume of solution imbibed and determined how calories and nutrients influenced LS and fecundity in unmated females of the Queensland fruit fly, Bactocera tryoni (Diptera: Tephritidae). We restricted flies to one of 28 diets varying in carbohydrate:protein (C:P) ratios and concentrations. On imbalanced diets, flies overcame dietary dilutions, consuming similar caloric intakes for most dilutions. The response surface for LS revealed that increasing C:P ratio while keeping calories constant extended LS, with the maximum LS along C:P ratio of 21:1. In general, LS was reduced as caloric intake decreased. Lifetime egg production was maximized at a C:P ratio of 3:1. When given a choice of separate sucrose and yeast solutions, each at one of five concentrations (yielding 25 choice treatments), flies regulated their nutrient intake to match C:P ratio of 3:1. Our results (i) demonstrate that CF can overcome dietary dilutions; (ii) reveal difficulties with methods presenting fixed amounts of liquid diet; (iii) illustrate the need to measure intake to account for CF in DR studies and (iv) highlight nutrients rather than CR as a dominant influence on LS.

    Full Text Available Tephritid fruit flies are amongst the most damaging insect pests of horticulture globally. Some of the key fruit fly species are managed using the sterile insect technique (SIT, whereby millions of sterile males are released to suppress reproduction of pest populations. Male annihilation technique (MAT, whereby sex specific lures are used to attract and kill males, is often used to reduce wild male numbers before SIT programs commence, providing released sterile males an increased numerical advantage. Overall program efficacy might be improved if MAT could be deployed simultaneously with SIT, continuously depleting fertile males from pest populations and replacing them with sterile males. However, such 'male replacement' requires a means of suppressing attraction of released sterile males to lures used in MAT. Previous studies have found that exposure of some fruit flies to lure compounds as mature adults can suppress subsequent response to those lures, raising the possibility of pre-release treatments. However, this approach requires holding flies until after maturation for treatment and then release. The present study takes a novel approach of exposing immature adult male Queensland fruit flies (Bactrocera tryoni, or 'Qfly' to raspberry ketone (RK mixed in food, forcing these flies to ingest RK at ages far younger than they would naturally. After feeding on RK-supplemented food for two days after emergence, male Qflies exhibited a reduction in attraction to cuelure traps that lasted more than 20 days. This approach to RK exposure is compatible with current practises, in which Qflies are released as immature adults, and also yields advantages of accelerated reproductive development and increased mating propensity at young ages.

    We report petrological and geochemical data on coeval trachybasalts, syenites with enclaves, trachytes, peralkaline rhyolites and peraluminous rhyolites from the Glass House Mountains-Maleny-Noosa area, southeast Queensland, Australia. This rock association and the unique characteristics of the peralkaline rhyolites offer convincing lines of evidence that the petrogenesis of the peralkaline rhyolites is a straightforward consequence of protracted fractional crystallization from basaltic melts of alkali-rich composition. Compared to the common peraluminous rhyolites elsewhere, the peralkaline rhyolites here are characterized by elevated abundances of most incompatible elements, especially the very high Nb (vs. Th) and Ta (vs. U), the very low Ba, Sr and Eu and the extremely high 87Sr/86Sr ratio. The high Nb and Ta are inherited from the parental alkali basaltic melts. The low Ba, Sr and Eu result from removal of plagioclase during the protracted fractional crystallization. These rocks altogether define a Rb-Sr isochron of ~ 28 Ma, which is similar to Ar-Ar age data on these rocks in the literature. The extremely high 87Sr/86Sr ratio of the peralkaline rhyolites (up to 1.88) is actually characteristic of peralkaline rhyolites because of extreme Sr (also Eu and Ba) depletion and thus the very high Rb/Sr ratio. That is, the Sr in these rocks is essentially radiogenic 87Sr accumulated from the 87Rb decay since the volcanism. We suggest that the petrogenesis of the peralkaline rhyolites from the Glass House Mountain area may be of general significance globally. The coeval peraluminous rhyolites apparently result from crustal anatexis in response to the basaltic magma underplating. The small "Daly Gap" exhibited in this rock association is anticipated during the protracted fractional crystallization from basaltic parent to the more evolved felsic varieties.

    Simple Summary Microchip identification has become an important tool to reunite stray dogs and cats with their owners, and is now compulsory in most states of Australia. Improvement of the microchipping system in Australia is limited by a lack of published Australian data documenting the problems experienced by shelter staff when using microchip data to contact the owner of a stray animal. In this study we determine the character and frequency of inaccurate microchip data to identify weaknesses in the current microchipping system. This information could be used to develop strategies that increase the accuracy of microchip data that will increase the reclaiming of stray animals. Abstract A lack of published information documenting problems with the microchip data for the reclaiming of stray animals entering Australian shelters limits improvement of the current microchipping system. A retrospective study analysing admission data for stray, adult dogs (n = 7258) and cats (n = 6950) entering the Royal Society for the Prevention of Cruelty to Animals (RSPCA) Queensland between January 2012 and December 2013 was undertaken to determine the character and frequency of microchip data problems and their impact on outcome for the animal. Only 28% of dogs and 9% of cats were microchipped, and a substantial proportion (37%) had problems with their data, including being registered to a previous owner or organisation (47%), all phone numbers incorrect/disconnected (29%), and the microchip not registered (14%). A higher proportion of owners could be contacted when the microchip had no problems, compared to those with problems (dogs, 93% vs. 70%; cats, 75% vs. 41%). The proportion of animals reclaimed declined significantly between microchipped animals with no data problems, microchipped animals with data problems and non-microchipped animals—87%, 69%, and 37%, respectively, for dogs and 61%, 33%, and 5%, respectively, for cats. Strategies are needed to increase the accuracy of

    young parenthood continues to be an issue of concern in terms of clinical and psychosocial outcomes for mothers and their babies, with higher rates of medical complications such as preterm labour and hypertensive disease and a higher risk of depression. The aim of this study was to investigate how young age impacts on women's experience of intrapartum care. secondary analysis of data collected in a population based survey of women who had recently given birth in Queensland, comparing clinical and interpersonal aspects of the intrapartum maternity care experience for 237 eligible women aged 15-20 years and 6534 aged more than 20 years. Descriptive and multivariate analyses were undertaken. in the univariate analysis a number of variables were significantly associated with clinical aspects of labour and birth and perceptions of care: young women were more likely to birth in a public facility, to travel for birth and to live in less economically advantaged areas, to have a normal vaginal birth and to have one carer through labour. They were also less likely to report being treated with respect and kindness and talked to in a way they could understand. In logistic regression models, after adjustment for parity, other socio-demographic factors and mode of birth, younger mothers were still more likely to birth in a public facility, to travel for birth, to be more critical about interpersonal and aspects of care and the hospital or birth centre environment. this study shows how experience of care during labour and birth is different for young women. Young women reported poorer quality interpersonal care which may well reflect an inferior care experience and stereotyping by health professionals, indicating a need for more effective staff engagement with young women at this time.

    The aim of this study was to explore the barriers to accessing medicines and pharmacy services among refugees in Queensland, Australia, from the perspectives of resettled African refugees. A generic qualitative approach was used in this study. Resettled African refugees were recruited via a purposive snowball sampling method. The researcher collected data from different African refugee communities, specifically those from Sudanese, Congolese and Somalian communities. Participants were invited by a community health leader to participate in the study; a community health leader is a trained member of the refugee community who acts as a 'health information conduit' between refugees and the health system. Invitations were done either face-to-face, telephonically or by email. The focus groups were digitally recorded in English and transcribed verbatim by the researcher. Transcripts were entered into NVIVO© 11 and the data were analysed using inductive thematic analysis. Four focus groups were conducted between October and November 2014 in the city of Brisbane with African refugees, one with five Somali refugees, one with five Congolese refugees, one with three refugee community health leaders from South Sudan, Liberia and Eritrea and one with three refugee community health leaders from Uganda, Burundi and South Sudan. Eleven sub-themes emerged through the coding process, which resulted in four overarching themes: health system differences, navigating the Australian health system, communication barriers and health care-seeking behaviour. With regard to accessing medicines and pharmacy services, this study has shown that there is a gap between resettled refugees' expectations of health services and the reality of the Australian health system. Access barriers identified included language barriers, issues with the Translating and Interpreter Service, a lack of professional communication and cultural beliefs affecting health care-seeking behaviour. This exploratory study has

    The cancer toll on Indigenous Australians is alarming with overall cancer incidence and mortality rates higher and the 5-year survival rate lower for Indigenous Australians compared with non-Indigenous Australians. Meanwhile, a range of approaches to health and illness-including both complementary and alternative medicine (CAM) and traditional Indigenous medicine (TM)-are used by cancer patients. Little work has focused on Indigenous cancer patients with regard to CAM/TM use. This article reports findings from the first examination of the prevalence and profile of TM/CAM use and users among Indigenous Australians with cancer. A structured questionnaire was administered via face-to-face interviews to 248 Indigenous Australian cancer patients diagnosed with a range of cancer types. All received treatment and were recruited from 1 of 4 large hospitals located in Queensland, Australia. A substantial percentage (18.7%) of Indigenous cancer patients use at least one TM/CAM for support with their care, including traditional Indigenous therapy use (2.8%), visiting a traditional Indigenous practitioner (2.8%), CAM use (10.7%), visiting a CAM practitioner (2.4%), and attending relaxation/meditation classes (4.0%). Having a higher level of educational attainment was positively associated with CAM practitioner consultations (P = .015). Women with breast cancer were more likely to attend relaxation/meditation classes (P = .019). Men with genital organ cancer were more likely to use traditional Indigenous therapies (P = .017) and/or CAM (P = .002). A substantial percentage of Indigenous Australians reported using TM/CAM for their cancer care, and there is a need to expand examination of this area of health care using large-scale studies focusing on in-depth specific cancer(s). © The Author(s) 2015.

    2016-06-02

    The extinct hemipteran family Scytinopteridae, the presumed ancestors of the Heteroptera, was a small but widely distributed element of the Triassic insect fauna of Queensland. A total of 28 tegmina have been collected at six sites (Gayndah, Esk, Mount Crosby, Riverview, Denmark Hill and Dinmore) in five Middle or Late Triassic Formations. The specimens are remarkably uniform in both wing shape and basic venation, and the generally weakly developed venation of the apical area of the tegmen is rarely clearly preserved. Some consistent variations in tegmen size and in minor venational characters, however, have enabled the identification of six and possibly seven species in three genera, acknowledging of course, the somewhat artificial nature of fossil insect species based solely on isolated wings. Mesoscytina Tillyard, 1919 (= Triassoscarta Tillyard, 1919, syn. nov.), comprising Mesoscytina australis Tillyard, 1919 (= Mesoscytina affinis Tillyard, 1919, syn. nov., = Triassoscarta subcostalis Tillyard, 1919, syn. nov.) (Denmark Hill, Esk), Mesoscytina fistulae sp. nov. (Mount Crosby, Gayndah), Mesoscytina woodsi sp. nov. (Gayndah), and Mesoscytina magna sp. nov. (Dinmore), is distinguished by the combination of the R more or less straight distally and M with three apical branches. The monotypic Eurymelidium Tillyard, 1919, with type species Eurymelidium australe Tillyard, 1919 (Denmark Hill, Dinmore), has R sinuous and M with two apical branches, and the monotypic Apheloscyta Tillyard, 1922, with type species Apheloscyta mesocampta Tillyard, 1922 (Denmark Hill, Riverview) has R more or less straight and M with two apical branches. Three poorly preserved and thus unidentifiable scytinopterid tegmina from Esk, similar in size to Mesoscytina fistulae, are designated as Esk species A.

    2013-01-01

    Background Research is a major driver of health care improvement and evidence-based practice is becoming the foundation of health care delivery. For health professions to develop within emerging models of health care delivery, it would seem imperative to develop and monitor the research capacity and evidence-based literacy of the health care workforce. This observational paper aims to report the research capacity levels of statewide populations of public-sector podiatrists at two different time points twelve-months apart. Methods The Research Capacity & Culture (RCC) survey was electronically distributed to all Queensland Health (Australia) employed podiatrists in January 2011 (n = 58) and January 2012 (n = 60). The RCC is a validated tool designed to measure indicators of research skill in health professionals. Participants rate skill levels against each individual, team and organisation statement on a 10-point scale (one = lowest, ten = highest). Chi-squared and Mann Whitney U tests were used to determine any differences between the results of the two survey samples. A minimum significance of p  6). Whereas, most reported their organisation’s skills to perform and support research at much higher levels (Median > 6). The 2012 survey respondents reported significantly higher skill ratings compared to the 2011 survey in individuals’ ability to secure research funding, submit ethics applications, and provide research advice, plus, in their organisation’s skills to support, fund, monitor, mentor and engage universities to partner their research (p < 0.05). Conclusions This study appears to report the research capacity levels of the largest populations of podiatrists published. The 2011 survey findings indicate podiatrists have similarly low research capacity skill levels to those reported in the allied health literature. The 2012 survey, compared to the 2011 survey, suggests podiatrists perceived higher skills and support to initiate

    Increases in the impervious area due to urbanisation have been shown to have negative impacts on the physical and ecological condition of streams, primarily through increased volume and frequency of runoff. The harvesting and detention of runoff has a potential to decrease this impact. This paper describes the effects of urbanisation on catchment flow and of stormwater harvesting on reducing those adverse impacts on a stream in South East Queensland (SEQ), Australia. A largely undeveloped catchment located southeast of Brisbane city was calibrated and validated using the Stormwater Management Model (SWMM). This model was used to investigate the effect of a range of future increases in urbanisation (represented by impervious area) on stream hydrology as well as the potential of stormwater harvesting to return the catchments to predevelopment flow conditions. Stormwater harvesting was modelled according to flow frequency measures specified in current SEQ development guidelines. These guidelines stipulate the capture of the first 10 mm of runoff from impervious areas of 0-40% and the first 15 mm from impervious areas of 40% or greater for urban developments. We found that increases in the impervious area resulted in increases in the mean, frequency and duration of high flows, and an increase in the mean rate of rise and fall for storm events in the catchment. However, the predevelopment (non-urbanised) flow distribution was very flashy in comparison with all urbanised scenarios; i.e. it had the quickest response to rainfall indicated by a high rate of rise to and fall from peak flow volume, followed by a return to zero flow conditions. Capturing the runoff according to the development guidelines resulted in a reduction in flow towards the flow distribution of a lower impervious area, however this was insufficient to meet predevelopment conditions. This suggests a stronger influence of impervious areas in this catchment on the volume of runoff than flow frequency

    A spatial analysis of hydrochemical data of groundwater and surface water was undertaken to identify groundwater-surface water connectivity in the headwaters of the Condamine River catchment, Southeast Queensland, Australia. An assessment of long-term hydrochemical and water level data supplemented by stable- and radioisotope measurements following a prolonged dry period dominated by baseflow, helped in determining patterns of interaction in different tributaries of the upper Condamine catchment. A conceptual hydrological model representing the major hydrochemical processes and their implications for stream-aquifer connectivity was developed and tested using multiple lines of evidence. The results of a multivariate statistical analysis highlight that there are two main regions with distinct hydrochemical facies (salinity, alkalinity, and predominant ions) in surface water. Geomorphology, geology, anthropogenic and climate influence were identified as the most relevant controlling factors of the spatial variability in water quality. Stable isotope data confirmed a clear evaporation trend in almost all surface water samples during baseflow conditions. Two water types can be identified and separated by the degree of evaporation and the proximity of one group to the local meteoric water line. The results confirm the discharge of groundwater from aquifers recharged by rainfall and located upstream of the surface water sampling sites. Overall, 222Rn data show a trend of increased activity in surface water towards the upstream portions of these tributaries, validating the use of this tracer to estimate groundwater input to the local creeks. The proportion of groundwater contribution to stream flow calculated by 222Rn and chloride mass balance is in agreement, and ranges between 20-70% in tributaries in the northern areas, and between 8-50% in the upper reaches of the main river channel. This study shows the efficacy of an integrated approach combining long

    Full Text Available Organic compounds in Australian coal seam gas produced water (CSG water are poorly understood despite their environmental contamination potential. In this study, the presence of some organic substances is identified from government-held CSG water-quality data from the Bowen and Surat Basins, Queensland. These records revealed the presence of polycyclic aromatic hydrocarbons (PAHs in 27% of samples of CSG water from the Walloon Coal Measures at concentrations <1 µg/L, and it is likely these compounds leached from in situ coals. PAHs identified from wells include naphthalene, phenanthrene, chrysene and dibenz[a,h]anthracene. In addition, the likelihood of coal-derived organic compounds leaching to groundwater is assessed by undertaking toxicity leaching experiments using coal rank and water chemistry as variables. These tests suggest higher molecular weight PAHs (including benzo[a]pyrene leach from higher rank coals, whereas lower molecular weight PAHs leach at greater concentrations from lower rank coal. Some of the identified organic compounds have carcinogenic or health risk potential, but they are unlikely to be acutely toxic at the observed concentrations which are almost negligible (largely due to the hydrophobicity of such compounds. Hence, this study will be useful to practitioners assessing CSG water related environmental and health risk.

This article examines the benefits, risks and limitations of curriculum development led by students. The Project aimed to trial student-led development of a Global Health curriculum module for the UQ medical programme, as part of an international collaboration with related Health Sciences activities of Universitas 21 (U21). The Head (Dean) of the UQ School of Medicine instigated the Project. A student Convenor was appointed to lead it and, in conjunction with faculty, to design curriculum Learning Objectives and supporting resources. The initial vision of the Project was greatly expanded, from an optional elective to a compulsory curriculum module with inbuilt prospective outcome measures. The module was established in less than 12 months and is now being delivered throughout the 4-year medical programme. A process for ongoing student leadership of the Project was established. Student-led learning can be effective if given adequate support by faculty. The UQ School of Medicine's new curriculum module and collaboration with U21 promote the teaching of Global Health.

    Understanding the relationship between incursions of insect pests and established populations is critical to implementing effective control. Studies of genetic variation can provide powerful tools to examine potential invasion pathways and longevity of individual pest outbreaks. The major fruit fly pest in eastern Australia, Queensland fruit fly Bactrocera tryoni (Froggatt), has been subject to significant long-term quarantine and population reduction control measures in the major horticulture production areas of southeastern Australia, at the species southern range limit. Previous studies have employed microsatellite markers to estimate gene flow between populations across this region. In this study, we used an independent genetic marker, mitochondrial DNA (mtDNA) sequences, to screen genetic variation in established and adjacent outbreak populations in southeastern Australia. During the study period, favorable environmental conditions resulted in multiple outbreaks, which appeared genetically distinctive and relatively geographically localized, implying minimal dispersal between simultaneous outbreaks. Populations in established regions were found to occur over much larger areas. Screening mtDNA (female) lineages proved to be an effective alternative genetic tool to assist in understanding fruit fly population dynamics and provide another possible molecular method that could now be employed for better understanding of the ecology and evolution of this and other pest species.

    After a disaster, the media typically focus on who is to blame. However, relatively little is known about how the narrative of blame plays out in media coverage of the release of official disaster reports. This paper examines coverage by two Australian newspapers (The Courier-Mail and The Australian) of the release of the Queensland Floods Commission of Inquiry's Interim Report and its Final Report to identify whether and how the news frame of blame was used. Given the absence of blame in the Final Report, the newspapers resorted to the frame of 'failure' in news and feature articles, while continuing to raise questions in editorials and opinion pieces about who was to blame. This study argues that situating coverage of the report within the news frame of failure and questioning who was to blame for the disaster limited the media's ability to facilitate a discussion about the prevention of similar disasters in the future. © 2014 The Author(s).

    We report a serendipitous discovery that extends the impressive catalog of reporter functions performed by green fluorescent protein (GFP) or its derivatives. When two GFP molecules are brought into proximity, changes in the relative intensities of green fluorescence emitted upon excitation at 395 vs. 475 nm result. These spectral changes provide a sensitive ratiometric index of the extent of self-association that can be exploited to quantitatively image homo-oligomerization or clustering processes of GFP-tagged proteins in vivo. The method, which we term proximity imaging (PRIM), complements fluorescence resonance energy transfer between a blue fluorescent protein donor and a GFP acceptor, a powerful method for imaging proximity relationships between different proteins. However, unlike fluorescence resonance energy transfer (which is a spectral interaction), PRIM depends on direct contact between two GFP modules, which can lead to structural perturbations and concomitant spectral changes within a module. Moreover, the precise spatial arrangement of the GFP molecules within a given dimer determines the magnitude and direction of the spectral change. We have used PRIM to detect FK1012-induced dimerization of GFP fused to FK506-binding protein and clustering of glycosylphosphatidylinositol-anchored GFP at cell surfaces. PMID:9770483

    To review the research progress of the biomechanics of proximal row carpal instability (IPRC). The related literature concerning IPRC was extensively reviewed. The biomechanical mechanism of the surrounding soft tissue in maintaining the stability of the proximal row carpal (PRC) was analyzed, and the methods to repair or reconstruct the stability and function of the PRC were summarized from two aspects including basic biomechanics and clinical biomechanics. The muscles and ligaments of the PRC are critical to its stability. Most scholars have reached a consensus about biomechanical mechanism of the PRC, but there are still controversial conclusions on the biomechanics mechanism of the surrounding soft tissue to stability of distal radioulnar joint when the triangular fibrocartilage complex are damaged and the biomechanics mechanism of the scapholunate ligament. At present, there is no unified standard about the methods to repair or reconstruct the stability and function of the PRC. So, it is difficult for clinical practice. Some strides have been made in the basic biomechanical study on muscle and ligament and clinical biomechanical study on the methods to repair or reconstruct the stability and function of PRC, but it will be needed to further study the morphology of carpal articular surface and the adjacent articular surface, the pressure of distal carpals to proximal carpal and so on.

    Reduced insulin receptor protein levels have been reported in the kidney cortex from diabetic humans and animals. We recently reported that, targeted deletion of insulin receptor (IR) from proximal tubules (PT) resulted in hyperglycemia in non-obese mice. To elucidate the mechanism, we examined human proximal tubule cells (hPTC) and C57BL/6 mice fed with high-fat diet (HFD, 60% fat for 20 weeks). Immunoblotting revealed a significantly lower protein level of IR in HFD compare to normal chow diet (NCD). Furthermore, a blunted rise in p-AKT 308 levels in the kidney cortex of HFD mice was observed in response to acute insulin (0.75 IU/kg body weight, i.p) relative to NCD n = 8/group, P gluconeogenesis. Transcript levels of the gluconeogenic enzyme PEPCK were significantly increased in cAMP/DEXA-stimulated hPTC cells (n = 3, P gluconeogenesis and PEPCK induction was significantly attenuated in IR (siRNA) silenced hPTC (n = 3, P gluconeogenesis. Thus reduced insulin signaling of the proximal tubule may contribute to hyperglycemia in the metabolic syndrome via elevated gluconeogenesis. J. Cell.

    To explore the knowledge of state abortion law of doctors providing abortion in New South Wales and Queensland, their attitudes towards this law, and their application of both knowledge and attitudes to their day-to-day practice of abortion. Qualitative study using interviews of twenty-two medical practitioners agreeing to participate and identified as providing surgical and/or medical abortions in NSW or Queensland. Specific questions about practice as well as responses to ten common clinical scenarios formed the basis of each interview. Familiarity of participants with abortion law of their state, documentation of views on legality and probable availability of abortion in each scenario provided. All participants were aware that abortion in their state is covered by criminal legislation, which they believe is out-of-date with current medical practice, in particular with regard to the diagnosis of serious fetal abnormality, and that there is limited case law to assist doctors in a defence to a charge of abortion. All were concerned about requirements to conform to state law when agreeing to provide abortion services to women, and about the possible constraints of these requirements on women's accessibility to abortion services. Review and reform of abortion laws in Queensland and NSW, as has occurred in other states and territories, has the potential to bring the law into conformity with current medical practice and to clarify the legal position of doctors providing abortion services, thereby providing an opportunity to improve women's accessibility to these services. © 2013 The Authors ANZJOG © 2013 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Tubulointerstitial fibrosis (TIF) is the hallmark of chronic kidney disease and best predictor of renal survival. Many different cell types contribute to TIF progression including tubular epithelial cells, myofibroblasts, endothelia, and inflammatory cells. Previously, most of the attention has centered on myofibroblasts given their central importance in extracellular matrix production. However, emerging data focuses on how the response of the proximal tubule, a specialized epithelial segment vulnerable to injury, plays a central role in TIF progression. Several proximal tubular responses such as de-differentiation, cell cycle changes, autophagy, and metabolic changes may be adaptive initially, but can lead to maladaptive responses that promote TIF both through autocrine and paracrine effects. This review discusses the current paradigm of TIF progression and the increasingly important role of the proximal tubule in promoting TIF both in tubulointerstitial and glomerular injuries. A better understanding and appreciation of the role of the proximal tubule in TIF has important implications for therapeutic strategies to halt chronic kidney disease progression.

    The ability to detect minute amounts of specific proteins or protein modifications in blood as biomarkers for a plethora of human pathological conditions holds great promise for future medicine. Despite a large number of plausible candidate protein biomarkers published annually, the translation to clinical use is impeded by factors such as the required size of the initial studies, and limitations of the technologies used. The proximity ligation assay (PLA) is a versatile molecular tool that has the potential to address some obstacles, both in validation of biomarkers previously discovered using other techniques, and for future routine clinical diagnostic needs. The enhanced specificity of PLA extends the opportunities for large-scale, high-performance analyses of proteins. Besides advantages in the form of minimal sample consumption and an extended dynamic range, the PLA technique allows flexible assay reconfiguration. The technology can be adapted for detecting protein complexes, proximity between proteins in extracellular vesicles or in circulating tumor cells, and to address multiple post-translational modifications in the same protein molecule. We discuss herein requirements for biomarker validation, and how PLA may play an increasing role in this regard. We describe some recent developments of the technology, including proximity extension assays, the use of recombinant affinity reagents suitable for use in proximity assays, and the potential for single cell proteomics.

    2015-09-01

    Full Text Available Size and shape of the mammalian proximal femur and taxon-specific distinctions in the relative proportions of the proximal articulation, the femoral neck and the proximal femoral diaphysis, are critical determinants in its adaptation to differential biomechanical stresses and observed locomotor habitus in different taxa. The morphometrics of the proximal femur are considered equally critical in the assessment of locomotor habitus of extinct fossil mammals, particularly extinct Miocene anthropoids and Plio-Pleistocene hominins. Analyses of size and shape of k=10 dimensions of the proximal femur were undertaken for a large sample series of two extant mammal families the Felidae and Hominidae using conventional multivariate statistical procedures, commonly used size-correction methods, and post-hoc tests of significance. While significant differences in form do exist, there are equally striking convergences in the functional morphology of extant hominid and felid taxa. Multivariate and bivariate allometric analyses confirm that the proximal femur of these two mammalian families share a common underlying structure manifest in a shared first common principal component. Nevertheless, while considerable convergences in general form of the proximal femur of African hominids and large-bodied felids are apparent, there exist equally discreet distinctions which are consistent with the differential structural demands imposed by their distinct locomotor and behavioural habitus.

    The build-up of intensity-as a function of the number, n(rcpl), of POST-C7 elements used for the excitation and reconversion of double-quantum (DQ) coherence (DQC)-is analysed for the fifteen distinct DQ correlation peaks that are observed experimentally for the eight separate (1)H resonances in a (1)H (500 MHz) DQ CRAMPS solid-state (12.5 kHz MAS) NMR spectrum of the dipeptide beta-AspAla (S. P. Brown, A. Lesage, B. Elena, and L. Emsley, J. Am. Chem. Soc., 2004, 126, 13230). The simulation in SPINEVOLUTION (M. Veshtort and R. G. Griffin, J. Magn. Reson., 2006, 178, 248) of t(1) ((1)H DQ evolution) FIDs for clusters of eight dipolar-coupled protons gives separate simulated (1)H DQ build-up curves for the CH(2)(a), CH(2)(b), CH(Asp), CH(Ala), NH and OH (1)H single-quantum (SQ) (1)H resonances. An analysis of both the simulated and experimental (1)H DQ build-up leads to the following general observations: (i) considering the build-up of (1)H DQ peaks at a particular SQ frequency, maximum intensity is observed for the DQC corresponding to the shortest H-H distance; (ii) for the maximum intensity (1)H DQ peak at a particular SQ frequency, the recoupling time for the observed maximum intensity depends on the corresponding H-H distance, e.g., maximum intensity for the CH(2)(a)-CH(2)(b) (H-H distance = 1.55 A) and OH-CH(Asp) (H-H distance = 2.49 A) DQ peaks is observed at n(rcpl) = 2 and 3, respectively; (iii) for DQ peaks involving a CH(2) proton at a non-CH(2) SQ frequency, there is much reduced intensity and a maximum intensity at a short recoupling time; (iv) for the other lower intensity (1)H DQ peaks at a particular SQ frequency, maximum intensity is observed for the same (or close to the same) recoupling time, but the relative intensity of the DQ peaks is a reliable indicator of the relative H-H distance-the ratio of the maximum intensities for the peaks at the CH(Ala) SQ frequency due to the two DQCs with the NH and OH protons are found to be approximately in the

    2014-11-01

    Following the emergence of Hendra virus (HeV), private veterinarians have had to adopt additional infection control strategies to manage this zoonosis. Between 1994 and 2010, seven people became infected with HeV, four fatally. All infected people were at a higher risk of exposure from contact with horses as they were either veterinary personnel, assisting veterinarians, or working in the horse industry. The management of emerging zoonoses is best approached from a One Health perspective as it benefits biosecurity as well as a public health, including the health of those most at risk, in this case private veterinarians. In 2011 we conducted a cross-sectional study of private veterinarians registered in Queensland and providing veterinary services to horses. The aim of this study was to gauge if participants had adopted recommendations for improved infection control, including the use of personal protective equipment (PPE), and the development of HeV specific management strategies during the winter of 2011. A majority of participants worked in practices that had a formal HeV management plan, mostly based on the perusal of official guidelines and an HeV field kit. The use of PPE increased as the health status of an equine patient decreased, demonstrating that many participants evaluated the risk of exposure to HeV appropriately; while others remained at risk of HeV infection by not using the appropriate PPE even when attending a sick horse. This study took place after Biosecurity Queensland had sent a comprehensive package about HeV management to all private veterinarians working in Queensland. However, those who had previous HeV experience through the management of suspected cases or had attended a HeV specific professional education programme in the previous 12 months were more likely to use PPE than those who had not. This may indicate that for private veterinarians in Queensland personal experience and face-to-face professional education sessions may be more

    A male Queensland koala (Phascolarctos cinereus adustus) at Kanazawa Zoological Gardens (Kanagawa, Japan) exhibited paralytic symptoms in the hind limbs. Computed tomography and magnetic resonance imaging revealed a mass on the left ventral side of the 11th to 13th thoracic vertebrae, and the presence of myelitis or edema in the spinal cord. The koala was under anesthesia during the examination and suddenly developed ventricular fibrillation and died. Necropsy revealed a firm flat ovoid hemorrhagic mass on the vertebrae. Following a microscopic examination including immunohistochemistry, the perivertebral mass was diagnosed as B cell lymphoma. Therefore, neoplastic cell infiltration into the spinal cord may cause paralytic symptoms in the hind limbs.

    Legionellae are frequent contaminants of potable water supplies, resulting in sporadic infections and occasional outbreaks. Isolates of Legionella were collected from urban test sites within South East Queensland and evaluated for their virulence potential in vitro. Two strains (from the species Legionella londiniensis and Legionella quinlivanii) were demonstrated to have the ability to infect human macrophages, while a strain from the species Legionella anisa did not maintain an infection over the same time course. This suggests that the spectrum of urban environmentally associated Legionella with potential to cause human disease might be greater than currently considered. Copyright © 2015 Institut Pasteur.

  17. Proximity to urban parks and mental health.

    2014-03-01

    Urban parks have received attention in recent years as a possible environmental factor that could encourage physical activity, prevent obesity, and reduce the incidence of chronic conditions. Despite long hypothesized benefits of parks for mental health, few park studies incorporate mental health measures. To test the association between proximity to urban parks and psychological distress. Cross-sectional analysis of individual health survey responses. Data were collected for a study of capital improvements of neighborhood parks in Los Angeles. A survey was fielded on a sample of residential addresses, stratified by distance from the park (within 400m, 800m, 1.6 km, and 3.2km; N=1070). We used multiple regression to estimate the relationship between the psychological distress as measured by the MHI-5 (outcome variable) and distance to parks (main explanatory variable), controlling for observed individual characteristics. Mental health is significantly related to residential distance from parks, with the highest MHI-5 scores among residents within short walking distance from the park (400m) and decreasing significantly over the next distances. The number of visits and physical activity minutes are significantly and independently related to distance, although controlling for them does not reduce the association between distance and mental health. This paper provides a new data point for an arguably very old question, but for which empirical data are sparse for the US. A nearby urban park is associated with the same mental health benefits as decreasing local unemployment rates by 2 percentage points, suggesting at least the potential of environmental interventions to improve mental health. The analysis is cross-sectional, making it impossible to control for important confounders, including residential selection. Mental health policy has traditionally focused on individual-centered interventions. Just as health policy for preventable chronic illnesses has shifted

    Laparoscopic proximal gastrectomy (LPG) with double tract reconstruction (DTR) is known to reduce reflux symptoms, which is a major concern after proximal gastrectomy. The aim of this study is to compare retrospectively the clinical outcomes of patients undergoing LPG with DTR with those treated by laparoscopic total gastrectomy (LTG). Ninety-two and 156 patients undergoing LPG with DTR and LTG for proximal stage I gastric cancer were retrospectively analyzed for short- and long-term clinical outcomes. There were no significant differences in the demographics, T-stage, N-stage, and complications between the groups. The LPG with DTR group had a shorter operative time and lower estimated blood loss than the LTG group (198.3 vs. 225.4 min, p DTR group compared to in the LTG group in the first and second postoperative years (5.03 vs. 9.18% p = 0.004; and 3.45 vs. 8.30%, p = 0.002, respectively), as was the mean amount of vitamin B12 supplements 2 years after operation (0.1 vs. 3.1 mg, p DTR maintained comparable oncological safety and anastomosis-related late complications compared to LTG and is preferred over LTG in terms of preventing postoperative anemia and vitamin B12 deficiency.

    Full Text Available Abstract Background Cross national drug utilization studies can provide information about different influences on physician prescribing. This is important for medicines with issues around safety and quality of use, like non selective non-steroidal anti-inflammatory drugs (ns-NSAIDs and cyclo-oxygenase-2 (COX-2 inhibitors. To enable comparison of prescription medicine use across different jurisdictions with a range of population sizes, data first need to be compared within Australia to understand whether use in a smaller sub-population may be considered as representative of the total use within Australia. The aim of this study was to compare the utilization of non selective NSAID, COX-2 inhibitors and paracetamol between Queensland and Australia. Method Dispensing data were obtained for concession beneficiaries for Australia for ns-NSAIDs, COX-2 inhibitors and paracetamol subsidized by the PBS over the period 1997–2003. The same data were purchased for Queensland. Data were converted to Defined Daily Dose (DDD/1000 beneficiaries/day (World Health Organization anatomical therapeutic chemical classification, 2005. Results Total NSAID and paracetamol consumption were similar in Australia and Queensland. Ns-NSAID use decreased sharply with the introduction of COX-2 inhibitors (from approximately 80 to 40 DDD/1000 beneficiaries/day. Paracetamol was constant (approximately 45 DDD/1000 beneficiaries/day. COX-2 inhibitors consumption was initially higher in Queensland than in the whole of Australia. Conclusion Despite initial divergence in celecoxib use between Queensland and Australia, the use of ns-NSAIDs, COX-2 inhibitors and paracetamol overall, in concession beneficiaries, was comparable in Australia and Queensland.

    Surgical management of proximal humerus fractures remains controversial and there is an increasing interest in intramedullary nailing. Created to improve previous designs, the T2-proximal humeral nail (PHN) (Stryker) has been recently released, and the English literature lacks a series evaluating its results. We present a clinical prospective study evaluating this implant for proximal humeral fractures. We evaluated the functional and radiological results and possible complications. Twenty-nine patients with displaced fractures of the proximal humerus were treated with this nail. One patient was lost right after surgery and excluded from the assessment. Eighteen patients were older than 70 years. There were 21 fractures of the proximal part of the humerus and 7 fractures that also involved the shaft; 15 of the fractures were two-part fractures (surgical neck), 5 were three-part fractures, and 1 was a four-part fracture. All fractures healed in a mean period of 2.7 months. There was one delayed union that healed in 4 months. One case of avascular necrosis of the humeral head was observed (a four-part fracture), but remained asymptomatic and did not require further treatment. In one case a back-out of one proximal screw was observed. A final evaluation with a minimum 1 year follow-up was performed by an independent observer; in 18 patients, the mean Constant score was 65.7 or 76.1% with the adjustment of age and gender; in 19 patients, the mean Oxford Shoulder Score was 21.7. The results obtained with the T2-PHN nail indicate that it represents a safe and reliable method in the treatment of two- and three-part fractures of the proximal humerus. The proximal fixation mechanism diminishes the rate of back-out of the screws, a frequent complication described in the literature. Better functional results were obtained from the patients younger than 70 years, but these were not statistically significant.

    The purpose of this study was to show a change in proximal femur surface strains following total hip arthroplasty and after the addition of BoneSource hydroxyapatite bone cement in the proximal region of an instrumented femur and to measure the surface strain on the proximal body. Seven third-generation composite femurs (Pacific Research Laboratories, Vashon, Wash) were instrumented with 12 uniaxial strain gages, 6 gages on the anterior face, and 6 gages on the posterior face of each femur. All femurs exhibited stress shielding since the strains in the proximal region were drastically reduced. There was a large decrease in strain in the mid-shaft region and small changes in strain in the distal region. The surface strains on the modular implant were relatively low.

    In current agricultural and industrial applications, soil moisture determination is limited to point-wise measurements and remote sensing technologies. The former has limitations on spatial resolution while the latter, although has greater coverage in three dimensions, but may not be representative of real-time hydrologic conditions of the substrate. This conference paper discusses the use of elongated soil moisture probes to describe the transient soil moisture profile of water-shedding soil cover trial plots in north Queensland, Australia. Three-metre long flat ribbon cables were installed at designed depths across a soil cover with substrate materials from mining activities comprising of waste rocks and blended tailings. The soil moisture measurement is analysed using spatial time domain reflectometry (STDR) (Scheuermann et al., 2009) Calibration of the flat ribbon cable's soil moisture measurement in waste rocks is undertaken in a glasshouse setting. Soil moisture retention and outflows are monitored at specific time interval by mass balance and water potential measurements. These data sets together with the soil hydrologic properties derived from laboratory and field measurements are used as input in the numerical code on unsaturated flow, Hydrus2D. The soil moisture calculations of the glasshouse calibration using this numerical method are compared with results from the STDR soil moisture data sets. In context, the purpose of the soil cover is to isolate sulphide-rich mine wastes from atmospheric interaction as oxidation and leaching of these materials may result to acid and metalliferous drainage. The long term performance of a soil cover will be described in terms of the quantities and physico-chemical characteristics of its outflows. With the soil moisture probes set at automated and pre-determined measurement time intervals, it is expected to distinguish between macropore and soil moisture flows during high intensity rainfall events and, also continuously

    Full Text Available Abstract Background Research is a major driver of health care improvement and evidence-based practice is becoming the foundation of health care delivery. For health professions to develop within emerging models of health care delivery, it would seem imperative to develop and monitor the research capacity and evidence-based literacy of the health care workforce. This observational paper aims to report the research capacity levels of statewide populations of public-sector podiatrists at two different time points twelve-months apart. Methods The Research Capacity & Culture (RCC survey was electronically distributed to all Queensland Health (Australia employed podiatrists in January 2011 (n = 58 and January 2012 (n = 60. The RCC is a validated tool designed to measure indicators of research skill in health professionals.

    Full Text Available Mount Isa, Queensland, is one of three Australian cities with significant lead emissions due to nonferrous mining and smelting. Unlike the two other cities with lead mines or smelters, Mount Isa currently has no system of annual, systematic, community-wide blood lead level testing; and testing rates among Indigenous children are low. In previous screenings, this group of children has been shown to have higher average blood lead levels than non-Indigenous children. The first aim of this study was to assess whether parents and children would participate in less invasive, rapid point-of-care capillary testing. The second aim was to measure blood lead levels among a range of children that roughly reflected the percentage of the Indigenous/non-Indigenous population. This pilot study is based on a convenience sample of children between the ages of 12 and 83 months who were recruited to participate by staff at a Children and Family Centre. Over three half-days, 30 children were tested using capillary blood samples and the LeadCare II Point-of-Care testing system. Rapid point-of-care capillary testing was well tolerated by the children. Of 30 children tested, 40% (n = 12 had blood lead levels ≥5 µg/dL and 10% had levels ≥10 µg/dL. The highest blood lead level measured was 17.3 µg/dL. The percentage of children with blood lead levels ≥5 µg/dL was higher among Indigenous children compared to non-Indigenous (64.2% compared to 18.8% as was the geometric mean level (6.5 (95% CI, 4.7, 9.2 versus 2.4 (95% CI, 1.8, 3.1, a statistically significant difference. Though based on a small convenience sample, this study identified 12 children (40% of the sample with blood lead levels ≥5 µg/dL. Due to historical and ongoing heavy metal emissions from mining and smelting in Mount Isa, we recommend a multi-component program of universal blood lead level testing, culturally appropriate follow-up and intervention for children who are identified with blood lead

    The Proximity Operations Nano-Satellite Flight Demonstration (PONSFD) program is to demonstrate rendezvous proximity operations (RPO), formation flying, and docking with a pair of 3U CubeSats. The program is sponsored by NASA Ames via the Office of the Chief Technologist (OCT) in support of its Small Spacecraft Technology Program (SSTP). The goal of the mission is to demonstrate complex RPO and docking operations with a pair of low-cost 3U CubeSat satellites using passive navigation sensors. The program encompasses the entire system evolution including system design, acquisition, satellite construction, launch, mission operations, and final disposal. The satellite is scheduled for launch in Fall 2015 with a 1-year mission lifetime. This paper provides a brief mission overview but will then focus on the current design and driving trade study results for the RPO mission specific processor and relevant ground software. The current design involves multiple on-board processors, each specifically tasked with providing mission critical capabilities. These capabilities range from attitude determination and control to image processing. The RPO system processor is responsible for absolute and relative navigation, maneuver planning, attitude commanding, and abort monitoring for mission safety. A low power processor running a Linux operating system has been selected for implementation. Navigation is one of the RPO processor's key tasks. This entails processing data obtained from the on-board GPS unit as well as the on-board imaging sensors. To do this, Kalman filters will be hosted on the processor to ingest and process measurements for maintenance of position and velocity estimates with associated uncertainties. While each satellite carries a GPS unit, it will be used sparsely to conserve power. As such, absolute navigation will mainly consist of propagating past known states, and relative navigation will be considered to be of greater importance. For relative observations

    The population structure of a tephritid pest species, the Queensland fruit fly Bactrocera tryoni (Froggatt), has been analysed over a five year period (1994-1998), using six microsatellites. Adult fly samples were collected to cover most regions of eastern and central Australia where the flies are regularly found. Tests for heterogeneity indicated that flies within geographically defined regions were homogeneous. The samples were allocated into five regions, including one very large region, Queensland, which encompasses that portion of the fly's range where breeding can occur year-round. With one exception, the collections from different regions were homogeneous between years, showing a fairly static distribution of the species. However, differences between regions were highly significant. The one case of a change in frequency between years indicated a gradual replacement of flies in a marginal region by flies from the main part of the range. The finding of stability in the distribution of a highly mobile insect is of interest, potentially also for other species which have expanded beyond their native range. It is argued that a contributing reason for this stability may be adaptation to different climatic regimes, and that strategies for control based on this hypothesis afford a reasonable chance of success.

    To describe the maternity care experiences of Aboriginal and/or Torres Strait Islander women in Queensland, Australia and to identify areas for policy and practice improvements. A culturally-tailored survey requesting both quantitative and qualitative information was completed by respondents either independently (online or in hard copy) or with the assistance of a trained peer-interviewer. Data were analysed using descriptive statistics and thematic analysis.Eligible women were over 16 years of age, identified as Aboriginal and/or Torres Strait Islander, resided in Queensland, and had a live, singleton birth between the first of July 2011 and the first of July 2012. 187 women of 207 respondents were included in analyses. Women reported high rates of stressful life events in pregnancy, low levels of choice in place of birth and model of care and limited options to carry out cultural practices. High levels of confidence in parenting were also reported. Women were less likely to report being treated with kindness, understanding and respect by maternity care staff than women answering a similar mainstream survey. Aboriginal and Torres Strait Islander women have additional needs to mainstream Australian women. This study identified a number of recommendations to improve services including the need to enhance the cultural competence of maternity services; increase access to continuity of midwifery care models, facilitate more choices in care, work with the strengths of Aboriginal and Torres Strait Islander women, families and communities, and engage women in the design and delivery of care.

    We describe the diversity of aquatic invertebrates colonising water-filled final voids produced by an open-cut coal mine near Moura, central Queensland. Ten disused pits that had been filled with water from < 1 year to 22 years prior to the survey and three nearby 'natural' water bodies were sampled in December 1998 and again in March 1999. All invertebrates collected were identified to family with the exception of oligochaetes, cladocerans, ostracods and copepods, which were identified to these coarser taxonomic levels. Sixty-two taxa were recorded from > 20 000 individuals. The greatest familial richness was displayed by the Insecta (33 families) followed by the mites (Acari) with 12 families. While natural water bodies held the greatest diversity, several mine pits were almost as rich in families. Classification analyses showed that natural sites tended to cluster together, but the groupings did not clearly exclude pit sites. Mining pits that supported higher diversity tended to be older and had lower salinity (< 2000 {mu}S/cm); however, salinity in all water bodies varied with rainfall conditions. We conclude that ponds formed in final voids at this mine have the potential to provide habitat for many invertebrate taxa typical of lentic inland water bodies in central Queensland.

    The recent industrial boom along the Australian coastline has increased concerns about the long term conservation of snubfin dolphins along the Queensland coast. National assessment of the conservation status and management of the Australian snubfin dolphin is currently hindered by the lack of adequate biological and ecological information throughout most of its range. In response to the issue of determining the conservation status of species with broad ranges, the IUCN has provided a framework for assessing the threatened status of regional populations. In this study we assessed the conservation status of a small geographically isolated population of snubfin dolphins living in the Fitzroy River region, Queensland, Australia, against the IUCN criteria for regional populations. A review of all available sightings data and stranding information indicates that this is the southernmost resident population of snubfin dolphins in Australian waters. The Fitzroy River snubfin dolphin population is composed of less than 100 individuals, with a representative range and core area of less than 400 and 300 km(2) respectively. The area most often used by snubfin dolphins within the representative range and core area was estimated to be about 292 and 191 km(2), respectively. A decrease in representative range, core area and preferred habitat between 14 and 25% is projected to occur if a planned industrial port development were to occur. These results are robust to uncertainty and considering the low level of formal protection and future threats, a classification of this subpopulation under the IUCN Red List as "Endangered" is appropriate.

    2015-01-01

    The shortage of a skilled mental health nursing workforce is persistent and worsening. Research consistently demonstrates the inability of the comprehensive model of nursing education to meet nursing workforce needs in mental health. Introducing specialisation in mental health at undergraduate level has been suggested as a strategy to address this problem. Exploration of barriers to this educational approach is essential. The aim of this research is to examine with Queensland Heads of Schools of Nursing, the perceived barriers to a specialist mental health nursing stream within an undergraduate nursing programme. Qualitative exploratory methods, involving in-depth telephone interviews with Heads of Schools of Nursing in Queensland, Australia. Data were analysed thematically. Participants encountered a number of barriers revealed in five main themes: academic staffing; staff attitudes; funding and resource implications; industry support; entry points and articulation pathways. Barriers to the implementation of mental health nursing specialisation in undergraduate programmes are evident. While these barriers pose real threats, potential solutions are also evident. Most notably is the need for Schools of Nursing to become more co-operative in mounting mental health nursing specialisations in a smaller number of universities, where specialist expertise is identified. Quality mental health services rely on a sufficiently skilled and knowledgeable nursing workforce. To achieve this it is important to identify and implement the educational approach best suited to prepare nurses for practice in this field.

    Only photographic prints and negative films of day-visible, day-IR and night-IR imagery were received. For northwest Queensland, only five day-visible and day-IR frames of acceptable quality were received. A master-grid was established over these frames within which selected grid sections are being enlarged photographically for the identification of stream courses and geological features permitting an interpretation of the imagery relative to ground truth information. The imagery is also being scanned and digitized using a Joyce-Loebl microdensitometer for classification purposes. For areas for which good quality HCMM imagery is available, valuable information is obtained on ephemeral and seasonal drainage systems. The day-IR cover is particularly helpful.

    2013-04-01

    Arthroscopy has become increasingly more established in the treatment of proximal humeral fractures. In addition to the known advantages of minimally invasive surgery fracture and implant positioning can be optimized and controlled arthroscopically and relevant intra-articular concomitant pathologies (e.g. biceps tendon complex and rotator cuff) can be diagnosed and treated. Arthroscopic techniques have proven to be advantageous in the treatment of various entities of greater tuberosity fractures, lesser tuberosity fractures (suture bridging technique) and subcapital humeral fractures (arthroscopic nailing). This article presents an overview on innovative arthroscopic modalities for treating proximal humeral fractures, describes the surgical techniques and the advantages compared to open procedures as well as initial clinical results.

    The characteristic length of the magnetic proximity effects exceed the thickness of a graphene layer leading to an important, but typically overlooked, modifications of equilibrium and transport properties, as well as the implications for graphene spintronics. Using the first-principles studies that integrate a real space density functional theory (GPAW) with the state-of-the art boundary elements electrostatic code based on the Robin Hood method, we explore tunable electronic structure and magnetic proximity effects in the ferromagnet/insulator/graphene junctions. We show that the inclusion of a finite-size gate electrodes and van der Walls interaction lead to nontrivial effects that could also be important in other two-dimensional materials beyond graphene.

    2016-01-01

    Full Text Available Dedifferentiated chondrosarcoma (DDCS comprises approximately 10% of all chondrosarcomas. The tumor generally occurs after the age of 50 years, with equal distribution among males and females. It is most often located in the bones of the pelvis, the proximal femur or humerus, the distal femur, and the ribs. Regardless of treatment, the prognosis is ominous with 90% of patients dying with distant metastases within 2 years. We report a case of DDCS of right proximal femur in a 73-year-old woman. The most important factors affecting survival are early recognition of the radiographic features, adequate histological sampling, and wide-margin resection of the lesion. So for the correct histopathological diagnosis the biopsy sample should be adequate to visualize both cartilaginous and noncartilaginous sarcomatous component which helps to increase the survival of patients before the distant metastasis occurs.

    Proximal humeral fractures, which typically occur in elderly persons, are among the most common fractures. A myriad of nonsurgical and surgical treatment options exist for these injuries, including short-term immobilization and early physical therapy, percutaneous fixation, plate osteosynthesis, intramedullary nailing, hemiarthroplasty, and reverse shoulder arthroplasty. The choice of treatment depends on the fracture type and severity, surgeon expertise, patient age, and patient health status.

    We investigate the superconducting proximity effect in clean ferromagnetic layers with rough boundaries. The subgap density of states is formed by Andreev bound states at energies which depend on trajectory length and the ferromagnetic exchange field. At energies above the gap, the spectrum is governed by resonant scattering states. The resulting density of states, measurable by tunneling spectroscopy, exhibits a rich structure, which allows us to connect the theoretical parameters from exper...

    Abstract Among stress fractures associated with sports activities, patellar stress fracture is rare. Regarding patella stress fractures, so far only distal transverse or lateral longitudinal fractures have been reported, but there are no reports of transverse fractures occurring in the proximal patella. We describe an extremely rare case of transverse stress fracture of proximal patella in a 9-year-old athlete. A 9-year old boy, who participated in sports (sprints and Kendo) presented with left knee pain without any external injury. In plain radiographs, a fracture line was observed in the proximal 1/3 of the left patella, and a patella stress fracture was diagnosed. For treatment, because 7 months of conservative therapy showed no improvement, internal fixation was carried out using Acutrak screws, and bone union was thus achieved. Three months after the operation, he was able to return to his previous level of athletic sports activity. Regarding the mechanism of onset, it is believed that the causes are longitudinal traction force and patellofemoral contact pressure. On the other hand, the contact region of the patella with the femur changes with the flexion angle of the knee. In the current case, the fracture occurred at a site where the patella was in contact with the femur at a flexion angle of >90°, so it is believed that it occurred as a clinical condition from being subjected to repeated longitudinal traction force and patellofemoral contact pressure at a flexion angle of >90°, during the sports activities of sprints and Kendo. The nonunion of the transverse stress fracture of his proximal patella was successfully treated with internal fixation using Acutrak screws. PMID:26871789

    Reducing the prevalence of obesity and chronic disease are important priorities. Maori and Pacific Islander communities living in Australia have higher rates of obesity and chronic disease than the wider Australian population. This study aims to assess the effectiveness of the Good Start program, which aims to improve knowledge, attitudes and practices related to healthy eating and physical activity amongst Maori and Pacific Islander communities living in Queensland. The intervention was delivered to children aged 6-19 years (N = 375) in schools by multicultural health workers. Class activities focused on one message each term related to healthy eating and physical activity using methods such as cooking sessions and cultural dance. The evaluation approach was a quantitative uncontrolled pre-post design. Data were collected each term pre- and post-intervention using a short questionnaire. There were significant increases in knowledge of correct servings of fruit and vegetables, knowledge of sugar and caffeine content of common sugar-sweetened drinks, recognition of the consequences of marketing and upsizing, and the importance of controlling portion size (all P foods regularly did not change significantly, suggesting that modifying the program with an increased emphasis on reducing intake of junk food may be beneficial. The study has shown that the Good Start Program was effective in engaging children from Maori and Pacific Island backgrounds and in improving knowledge, and some attitudes and practices, related to healthy eating and physical activity. The evaluation contributes valuable information about components and impacts of this type of intervention, and considerations relevant to this population in order to successfully change behaviours and reduce the burden of chronic disease.

  7. Proximal Gastrojejunal Reconstruction after Pancreaticoduodenal Resection

    2012-01-01

    Full Text Available Introduction. Reconstruction by proximal gastrojejunostomy, and distal biliary and pancreatic anastomoses is infrequently used after resection of the head of the pancreas because of fear of fistulas and cholangitis. Pancreaticoduodenectomy is being performed more frequently for cystic malignant and premalignant lesions. Because of this there is a need for endoscopic visualization and biopsy of the residual pancreatic duct, since multi-centricity is characteristic of some of these malignancies. Since endoscopic access of the bile duct and pancreatic duct is difficult and unsuccessful in 50–70% after B II or Roux Y reconstruction, we prospectively studied the merit and complications (early and late of proximal gastrojejunal (PGJ reconstruction after pancreaticoduodenal resection. Material and Methods. Thirty nine consecutive, non-radomized patients underwent pancreaticoduodenectomy and PGJ reconstruction over 14 mos. There were 21 males and 18 females. Results. 7 patients with IPMN have undergone repeat CT scanning for surveillance, with 3 requiring repeat EUS and ERCP. There were no technical difficulties accessing the pancreas or the pancreatic duct, supporting the PGJ reconstruction. Conclusion. Proximal gastrojejunal reconstruction following pancreaticoduodenal resection may be safely done with similar morbidity to traditional pancreaticojejunal reconstructions. PGJ reconstruction may be of greater value when direct visual access to the bile duct or pancreatic duct is necessary, and should be considered when doing resection for mucinous cysts or IPMN of the head of the pancreas.

    Dislocation of the tibiofibular joint is rare and usually results from a traumatic event. Only 1 case of atraumatic proximal tibiofibular joint instability in a 14-year-old girl has been reported in the literature, however this condition might occur more frequently than once thought. A wide range of treatment options exist for tibiofibular dislocations. Currently, the first choice is a conservative approach, and when this fails, surgical means such as resection of the fibula head, arthrodesis, and reconstruction are considered. However, no consensus exists on the most effective treatment. This article reports a unique case of bilateral, atraumatic, proximal tibia and fibular joint instability involving a 30-year-old man with a 20-year history of pain and laxity in the right knee. The patient had no trauma to his knees; he reported 2 immediate family members with similar complaints, which suggests that this case is likely congenital. After conservative approaches proved to be ineffective, the patient underwent capsular reconstruction using free autologous gracilis tendon. At 6-month postoperative follow-up, the patient was pain free with no locking and instability. He then underwent surgery on the left knee. At 1-year follow-up after the second surgery, the patient had no symptoms or restrictions in mobility. We provide an alternative surgical approach to arthrodesis and resection for the treatment of chronic proximal tibiofibular instability. In the treatment of chronic tibiofibular instability, we believe that reconstruction of the tibiofibular joint is a safe and effective choice. Copyright 2011, SLACK Incorporated.

    Variations in the oxygen isotopic composition of precipitation (δ18Oprecipitation) in inter-tropical areas mainly record variations in water sources, amounts of precipitation, and atmospheric temperature and provide information regarding local climate and regional atmospheric circulation changes. On continents, fossil biogenic minerals and speleothems formed in isotopic equilibrium with water can produce continuous δ18O records and are becoming increasingly valuable for reconstructing past climate changes. Here, we explore the efficiency and limitations of using the oxygen isotopic composition of wood phytoliths (δ18Owood phytolith) from tropical rainforest soils as a suitable proxy for atmospheric temperature and δ18Oprecipitation values, under conditions that are assumed to be non-evaporative. Soil phytolith assemblages, that should contain 100s of years of phytolith production, were collected along four altitude, temperature, and precipitation gradients in the Queensland rainforests (Australia). Oxygen isotopic analyses were performed on 1.6 mg phytolith samples, after controlled isotopic exchange (CIE), using the IR Laser-Heating Fluorination Technique. Long-term mean annual precipitation (MAP) and mean annual temperature (MAT) values at the sampled sites were obtained using a regional GIS database. The δ18Oprecipitation values were estimated. The δ18Owood phytolith values from the leeward slopes were scattered but recorded the modern combination of weighted mean annual δ18Oprecipitation values and MAT. The empirical relationship was &Delta18Owood phytolith-precipitation (‰ vs. VSMOW) = -0.4 (±0.2) t (°C) + 46 (±3) (R2 = 0.4, p<0.05; n=12). δ18Oprecipitation estimates were close to estimates for δ18Oforming water when using the temperature-dependant relationships previously described for sedimentary diatoms and natural quartz. However, they were 3 ‰ higher than estimates for δ18Oforming water when using the fractionation relationship obtained

    A predictive model for streamflow has practical implications for understanding the drought hydrology, environmental monitoring and agriculture, ecosystems and resource management. In this study, the state-or-art extreme learning machine (ELM) model was utilized to simulate the mean streamflow water level (Q WL) for three hydrological sites in eastern Queensland (Gowrie Creek, Albert, and Mary River). The performance of the ELM model was benchmarked with the artificial neural network (ANN) model. The ELM model was a fast computational method using single-layer feedforward neural networks and randomly determined hidden neurons that learns the historical patterns embedded in the input variables. A set of nine predictors with the month (to consider the seasonality of Q WL); rainfall; Southern Oscillation Index; Pacific Decadal Oscillation Index; ENSO Modoki Index; Indian Ocean Dipole Index; and Nino 3.0, Nino 3.4, and Nino 4.0 sea surface temperatures (SSTs) were utilized. A selection of variables was performed using cross correlation with Q WL, yielding the best inputs defined by (month; P; Nino 3.0 SST; Nino 4.0 SST; Southern Oscillation Index (SOI); ENSO Modoki Index (EMI)) for Gowrie Creek, (month; P; SOI; Pacific Decadal Oscillation (PDO); Indian Ocean Dipole (IOD); EMI) for Albert River, and by (month; P; Nino 3.4 SST; Nino 4.0 SST; SOI; EMI) for Mary River site. A three-layer neuronal structure trialed with activation equations defined by sigmoid, logarithmic, tangent sigmoid, sine, hardlim, triangular, and radial basis was utilized, resulting in optimum ELM model with hard-limit function and architecture 6-106-1 (Gowrie Creek), 6-74-1 (Albert River), and 6-146-1 (Mary River). The alternative ELM and ANN models with two inputs (month and rainfall) and the ELM model with all nine inputs were also developed. The performance was evaluated using the mean absolute error (MAE), coefficient of determination (r (2)), Willmott's Index (d), peak deviation (P dv), and Nash

    Growing interest in the structure and dynamics of animal social networks has stimulated efforts to develop automated tracking technologies that can reliably record encounters in free-ranging subjects. A particularly promising approach is the use of animal-attached 'proximity loggers', which collect data on the incidence, duration and proximity of spatial associations through inter-logger radio communication. While proximity logging is based on a straightforward physical principle - the attenuation of propagating radio waves with distance - calibrating systems for field deployment is challenging, since most study species roam across complex, heterogeneous environments.In this study, we calibrated a recently developed digital proximity-logging system ('Encounternet') for deployment on a wild population of New Caledonian crows Corvus moneduloides. Our principal objective was to establish a quantitative model that enables robust post hoc estimation of logger-to-logger (and, hence, crow-to-crow) distances from logger-recorded signal-strength values. To achieve an accurate description of the radio communication between crow-borne loggers, we conducted a calibration exercise that combines theoretical analyses, field experiments, statistical modelling, behavioural observations, and computer simulations.We show that, using signal-strength information only, it is possible to assign crow encounters reliably to predefined distance classes, enabling powerful analyses of social dynamics. For example, raw data sets from field-deployed loggers can be filtered at the analysis stage to include predominantly encounters where crows would have come to within a few metres of each other, and could therefore have socially learned new behaviours through direct observation. One of the main challenges for improving data classification further is the fact that crows - like most other study species - associate across a wide variety of habitats and behavioural contexts, with different signal

    The influence of mountain front recharge on the water balance of alluvial valley aquifers located in upland catchments of the Condamine River basin in Queensland, Australia, is investigated through the development of an integrated hydrogeological framework. A combination of three-dimensional (3D) geological modelling, hydraulic gradient maps, multivariate statistical analyses and hydrochemical mixing calculations is proposed for the identification of hydrochemical end-members and quantification of the relative contributions of each end-member to alluvial aquifer recharge. The recognised end-members correspond to diffuse recharge and lateral groundwater inflows from three hydrostratigraphic units directly connected to the alluvial aquifer. This approach allows mapping zones of potential inter-aquifer connectivity and areas of groundwater mixing between underlying units and the alluvium. Mixing calculations using samples collected under baseflow conditions reveal that lateral contribution from a regional volcanic aquifer system represents the majority (41%) of inflows to the alluvial aquifer. Diffuse recharge contribution (35%) and inflow from two sedimentary bedrock hydrostratigraphic units (collectively 24%) comprise the remainder of major recharge sources. A detailed geochemical assessment of alluvial groundwater evolution along a selected flowpath of a representative subcatchment of the Condamine River basin confirms mixing as a key process responsible for observed spatial variations in hydrochemistry. Dissolution of basalt-related minerals and dolomite, CO2 uptake, ion-exchange, precipitation of clay minerals, and evapotranspiration further contribute to the hydrochemical evolution of groundwater in the upland alluvial aquifer. This study highlights the benefits of undertaking an integrated approach that combines multiple independent lines of evidence. The proposed methods can be applied to investigate processes associated with inter-aquifer mixing, including

    Release from prison is a period of elevated risk for drug-related harms, particularly among people who inject drugs (PWID). Non-fatal overdose can cause serious morbidity and predicts future fatal overdose, however neither the incidence nor the risk factors for non-fatal overdose following release from prison are well understood. Structured health-related interviews were conducted with 1051 adult prisoners in Queensland, Australia prior to release and approximately 1, 3 and 6 months post-release. Incidence of self-reported overdose in the community was calculated for PWID and all prisoners for three discrete time periods. Negative binomial regression with robust error variance was used to identify pre-release predictors of overdose among PWID. The incidence of reported overdose was highest between 1 and 3 months post-release (37.8 per 100 person-years (PY) among PWID; 24.5/100 PY among all ex-prisoners). In adjusted analyses, the risk of post-release non-fatal overdose was higher for PWID who reported: being unemployed for >6 months before prison, having been removed from family as a child, at least weekly use of benzodiazepines and/or pharmaceutical opiates in the 3 months prior to prison, and ever receiving opioid substitution therapy (OST). Pre-release psychological distress and a lifetime history of mental disorder also predicted overdose, whereas risky alcohol use in the year before prison was protective. PWID have a high risk of overdose following release from prison. Imprisonment is an opportunity to initiate targeted preventive interventions such as OST, overdose prevention training and peer-delivered naloxone for those with a high risk profile.

    Full Text Available AIM: Technique for the fixation of two, three, and four part proximal humerus fractures has rapidly shifted towards the use of locking plates. The objective of this prospective study was to evaluate functional outcome and complications of proximal humeral fractures managed with proximal humerus internal locking system (PHILOS. METHODS: 16 men and 9 women aged 19 to 82 (mean, 49.24 with an acute proximal humerus fracture were treated with PHILOS plate by using deltopectoral approach. Outcome measurements included Constant score, complications, and radiographic assessment. RESULTS: 11 patients had 2-part fractures, 11 patients had 3-part fractures, and 3 patients had 4-part fractures. After 6 month follow up, a mean Constant score 57.4 was achieved. Outcomes were excellent in 16%, good in 44%, fair in 16% while poor in 24%. The Constant score was poorer for Neer type IV fractures as compared to other types. The most frequently occurring complications in our patients were malreduction 20%, screw perforation 16%, infection 12%, avascular necrosis 8%, frozen shoulder 8%, impingement 4% and plate pull out 4%. CONCLUSION: Fixation of proximal humerus fractures with proximal humerus locking plates is associated with satisfactory functional outcomes in 2-part and 3-part fracture. The incidence of complications and subsequent re-operation is relatively high. Advanced surgical skills and surgeon’s experience are considered to be more critical for successful operative treatment.

    Proximity logging is a new tool for understanding social behavior as it allows for accurate quantification of social networks. We report results from field calibration and deployment tests of miniaturized proximity tags (Encounternet), digital transceivers that log encounters between tagged individuals. We examined radio signal behavior in relation to tag attachment (tag, tag on bird, tag on saline-filled balloon) to understand how radio signal strength is affected by the tag mounting technique used for calibration tests. We investigated inter-tag and inter-receiver station variability, and in each calibration test we accounted for the effects of antennae orientation. Additionally, we used data from a live deployment on breeding barn swallows (Hirundo rustica erythrogaster) to analyze the quality of the logs, including reciprocal agreement in dyadic logs. We evaluated the impact (in terms of mass changes) of tag attachment on the birds. We were able to statistically distinguish between RSSI values associated with different close-proximity (social networks were constructed from proximity tag logs based on two different RSSI thresholds. There was no evidence of significant mass loss in the time birds were wearing tags. We conclude that proximity loggers are accurate and effective for quantifying social behavior. However, because RSSI and distance cannot be perfectly resolved, data from proximity loggers are most appropriate for comparing networks based on specific RSSI thresholds. The Encounternet system is flexible and customizable, and tags are now light enough for use on small animals (<50 g).

    The purpose of this study was to investigate how to detect proximal caries using line profile and validate linear measurements of proximal caries lesions by basic digital manipulation of radiographic images. The X-ray images of control group (15) and caries teeth (15) from patients were used. For each image, the line profile at the proximal caries-susceptible zone was calculated. To evaluate the contrast as a function of line profile to detect proximal caries, a difference coefficient (D) that indicates the relative difference between caries and sound dentin or intact enamel was measured. Mean values of D were 0.0354 {+-} 0.0155 in non-caries and 0.2632 {+-} 0.0982 in caries (p<0.001). The mean values of caries group were higher than non-caries group and there was correlation between proximal dental caries and D. It is demonstrated that the mean value of D from caries group was higher than that of control group. From the result, values of D possess great potentiality as a new detection parameter for proximal dental caries.

    To evaluate the effects of add-on distal upper limb robot-assisted treatment on the outcome of proximal regions. 64 chronic stroke patients divided into two groups participated in the study. Group A was assigned to the proximal robot-assisted rehabilitation, Group B to the proximal and distal. Shoulder/elbow subsection of Fugl-Meyer Assessment scale was collected for Group A, whereas for Group B wrist subsection was also collected. Motricity Index was used and a set of kinematic parameters was computed for both groups. A decrease in impairment after the treatment in both groups of patients (Group A: Shoulder/elbow FM p robot-assisted treatment in both groups; group B showed a greater improvement in velocity. Robotic treatment is effective to reduce motor impairment in chronic stroke patients even if distal training added to proximal segments in the Group B does not provide any incremental benefit to the proximal segments. It remains unclear if the effectiveness of robot-assisted treatment is directly related to the upper limb segment specifically treated and which order may lead to better outcome. Our study suggests that kinematic parameters should be computed in order to better clarify the role of distal training (wrist) on proximal segments (shoulder/elbow) as well.

  4. The role of integrative taxonomy in the conservation management of cryptic species: the taxonomic status of endangered earless dragons (Agamidae: Tympanocryptis in the grasslands of Queensland, Australia.

    Directory of Open Access Journals (Sweden)

    Jane Melville

    Full Text Available Molecular phylogenetics is increasingly highlighting the prevalence of cryptic species, where morphologically similar organisms have long independent evolutionary histories. When such cryptic species are known to be declining in numbers and are at risk of extinction due to a range of threatening processes, the disjunction between molecular systematics research and conservation policy becomes a significant problem. We investigate the taxonomic status of Tympanocryptis populations in Queensland, which have previously been assigned to T. tetraporophora, using three species delimitation approaches. The taxonomic uncertainties in this species-group are of particular importance in the Darling Downs Earless Dragon (T. cf. tetraporophora, which is ranked as an endangered 'species' of high priority for conservation by the Queensland Department of Environment and Heritage Protection. We undertook a morphological study, integrated with a comprehensive genetic study and species delimitation analyses, to investigate the species status of populations in the region. Phylogenetic analyses of two gene regions (mtDNA: ND2; nuclear: RAG1 revealed high levels of genetic divergence between populations, indicating isolation over long evolutionary time frames, and strongly supporting two independent evolutionary lineages in southeastern Queensland, from the Darling Downs, and a third in the Gulf Region of northern Queensland. Of the three species delimitation protocols used, we found integrative taxonomy the most applicable to this cryptic species complex. Our study demonstrates the utility of integrative taxonomy as a species delimitation approach in cryptic complexes of species with conservation significance, where limited numbers of specimens are available.

    Regulatory focus theory proposes 2 self-regulatory orientations: promotion focus - related to achieving aspirations and positive outcomes - and prevention focus - related to fulfilling responsibilities and preventing negative outcomes. The investigation examined whether regulatory focus and proximity to goal weight moderated the effectiveness of a weight-loss maintenance intervention. Participants who lost ≥10% of their weight were assigned to guided or self-directed treatments and completed regulatory focus and weight goal measures. Across treatment groups, people who were more promotion-focused had better 2-year maintenance rates (defined as regain focused, especially if far from their goal weight (.59 versus .44). In the guided group, people who were more prevention-focused had better maintenance rates than people who were less prevention-focused if closer to their goal weight (.69 versus .42), but poorer maintenance rates if farther from their goal (.36 versus .72). In the self-directed group, prevention focus was unrelated to maintenance. Regulatory focus and proximity to goal weight moderated intervention effectiveness. Maintenance may be enhanced by tailoring treatments to regulatory focus and goal weight (eg, prevention-focused people far from their goals may need extra weight-loss support before focusing on maintenance).

    Advanced proximal carpal row damage is common in rheumatoid arthritis (RA). Proximal row carpectomy (PRC) simplifies total wrist arthrodesis, obviating the need for an iliac bone graft. In theory, PRC also improves the chances of healing, as fusion of a single joint space is needed for the procedure to be successful. Potential effects of the loss of carpal height related to PRC are unknown. We hypothesised that PRC performed concomitantly with total wrist arthrodesis in patients with RA produces good clinical and radiological outcomes, without inducing loss of strength or digital deformities. In 38 total arthrodeses of rheumatoid wrists, a clinical evaluation was performed, including a visual analogue scale (VAS) pain score, the Patient-Rated Wrist Evaluation (PRWE), grip strength, digital deformities, and patient satisfaction. A standard radiographic workup was obtained to assess healing and carpal height indices. After a mean follow-up of 50 months, the mean VAS pain score was 0.4 (range: 0-7), the mean PRWE score was 21 (range: 0-80.5), and grip strength as a percentage of the contralateral limb was 76%. The healing rate was 92% (35/38 wrists), and 34 (90%) patients reported being satisfied or very satisfied. No effects of carpal height loss on clinical or radiographic parameters was detected. Total wrist arthrodesis combined with PRC provides reliable and reproducible benefits. This study found no evidence of adverse effects related to the loss of carpal height. IV, retrospective study.

    Decision makers in the water sector need to deal with existing hydroclimatic variability and uncertainty about future changes to climate and catchment conditions. Identifying solutions for hydroclimatic risk adaptation strategies that are both optimal and robust in the presence of variability and uncertainty presents a difficult challenge. A major reason for this challenge is the fact that the instrumental record in Australia is short ( 60-130 years) and fails to encompass enough climate variability to allow the calculation of robust statistics around the baseline risk of extreme events (e.g. multi-year droughts, decadal periods with clustering of major flood events). This climate variability is documented pre-1900 in palaeoclimate records from sources such as corals, tree-rings, freshwater and marine sediments. Despite being remote from Queensland, a high resolution and highly correlated palaeoclimate record from the Law Dome ice cores in Antarctica (Vance et al. 2015) is also now available and has identified eight mega-droughts (lasting from 5-39 years) during 1000-2009 AD. Most importantly, the palaeoclimate information confirms that the post-1900 instrumental period (i.e. the period on which all water resources infrastructure, policy, operation rules and strategies is based) does not capture the full range of variability that has occurred. Other work also clearly shows that, out to 2050 at least, impacts associated with natural variability significantly exceed even the worst-case climate change scenarios (i.e. obtained from Global Climate Models run under the highest emission scenarios). This presentation will demonstrate how the Law Dome ice cores from Antarctica have been used to produce a highly accurate, 1000 year, annual and seasonal resolution, hydroclimate reconstruction (i.e. precipitation and streamflow) for the southeast Queensland region of Australia. We will then show how the palaeoclimate data has been incorporated into the South East Queensland

    Objective The provision of healthcare services to inmates in correctional facilities is costly and resource-intensive. This study aimed to estimate the costs of transporting prisoners from 11 Queensland correctional facilities to the Princess Alexandra Hospital Secure Unit (PAHSU) in Brisbane for non-urgent specialist outpatient consultations and identify the cost consequences that would result from the substitution of face-to-face visits with telehealth consultations.Methods A 12-month retrospective review of patient activity at the PAHSU was conducted to obtain the number of transfers per correctional facility. The total cost of transfers was calculated with estimates for transport vehicle costs and correctional staff escort wages, per diem and accommodation costs. A cost model was developed to estimate the potential cost savings from substituting face-to-face consultations with telehealth consultations. A sensitivity analysis on the cost variables was conducted. Costs are reported from a government funding perspective and presented in 2016 Australian dollars (A$).Results There were 3539 inmate appointments from July 2015 to June 2016 at the PAHSU, primarily for imaging, general practice, and orthopaedics. Telehealth may result in cost savings from negligible to A$969731, depending on the proportion, and travel distance, of face-to-face consultations substituted by telehealth. Wages of correctional staff were found to be the most sensitive variable.Conclusions Under the modelled conditions, telehealth may reduce the cost of providing specialist outpatient consultations to prisoners in Queensland correctional facilities. Telehealth may improve the timeliness of services to a traditionally underserved population.What is known about the topic? Specialist medical services are located in only a few metropolitan centres across Australia, which requires some populations to travel long distances to attend appointments.

    1996-03-01

    Four epithermal vein deposits (i.e. Dawn, Central Extended, Rose’s Pride and Klondyke) in the Cracow gold field, central Queensland were investigated in terms of paragenesis, mineralogy, vein textures, fluid inclusions and stable isotopes. The Cracow epithermal field is confined to an area approximately 6 by 5 kilometers. All the deposits are hosted by the massive Camboon Andesite of Upper Carboniferous to Lower Permian age, occur as open-space vein fillings, and have similar paragenesis. However, significant variations in mineralogy, textures of quartz and adularia, and fluid geochemistry were found for a main mineralisation stage (Stage II) of each individual deposits. At Rose’s Pride and Klondyke, base-metal sulphides are virtually absent, but significant amounts of calcite and quartz with minor adularia are widely distributed. Replacement textures are distinct, and mineralisation temperature is less than 220 °C and salinity less than 0.2 wt%. The δ18O values of quartz and calcite range from -2.65 to -2.06‰ and from -6.66 to -6.34‰ respectively, and calculated δ18OH2O value is about -17‰ which represents a nearly unshifted palaeo-meteoric water. Gold mineralisation is best developed at Central Extended among the studied deposits, where patches rich in electrum are often observed in polished thin sections and where gold grades exceeding 10 g/t are frequently indicated by assays. Base-metal sulphides are only present locally and rarely exceed 5 volume percent of the vein samples. Quartz is the dominant gangue mineral, but significant amounts of rhombic adularia and chlorite are widely distributed. Various primary and recrystallisation textures possibly inherited from silica gel are well developed and widespread. At individual sites where crustiform bands developed from both walls of a fissure, temperatures could drop sharply from 275 °C to less than 220 °C.

  15. Delayed homicides and the proximate cause.

    Science.gov (United States)

    Lin, Peter; Gill, James R

    2009-12-01

    Delayed homicides result from complications of remote injuries inflicted by "the hands of another." The investigation of delayed homicides may be a challenge due to a number of factors including: failure to report the death to the proper authorities, lack of ready and adequate documentation of the original injury and circumstances, and jurisdictional differences between the places of injury and death. The certification of these deaths also requires the demonstration of a pathophysiologic link between the remote injury and death. In sorting through these issues, it is helpful to rely upon the definition of the proximate cause of death. Over a 2-year period in New York City, there were 1211 deaths certified as homicide of which 42 were due to injuries sustained greater than 1 year before death. The survival interval ranged from 1.3 to 43.2 years. The most common immediate causes of death were: infections (22), seizures (7), and intestinal obstructions/hernias (6). Common patterns of complications included infection following a gunshot wound of the spinal cord, seizure disorder due to blunt head trauma, and intestinal obstruction/hernia due to adhesions from an abdominal stab wound. Spinal cord injuries resulted in paraplegia in 14 instances and quadriplegia in 8. The mean survival interval for paraplegics was 20.3 years and 14.8 years for quadriplegics; infections were a frequent immediate cause of death in both groups, particularly infections due to chronic bladder catheterization. The definition of proximate cause originated with civil law cases and was later applied to death certification as the proximate cause of death. The gradual extinction of the "year and a day rule" for the limitation of bringing homicide charges in delayed deaths may result in more of these deaths going to trial. Medical examiners/coroners must be able to explain the reasoning behind these death certifications and maintain consistent standards for the certification of all delayed deaths due

    Proximal early gastric cancer is a good indication for totally laparoscopic proximal gastrectomy (TLPG) with double-tract reconstruction (DTR). However, when most of the dietary intake passes through the escape route of the jejunum, the functional benefits of proximal gastrectomy might be similar to those after total gastrectomy. Our DTR procedure was improved for easy passage through the remnant stomach. The purposes of this study were to present a novel technique for intracorporeal DTR using linear staplers after TLPG and to investigate surgical outcomes. DTR was performed using linear staplers only. A side-to-side jejunogastrostomy with twisting of both the remnant stomach and the anal jejunum was performed for the purpose of passing meals through the remnant stomach (an oblique jejunogastrostomy technique). The ten patients who underwent TLPG with DTR from January 2011 to August 2016 in Hokkaido University Hospital were retrospectively reviewed. Their clinicopathological characteristics and surgical and postoperative outcomes were collected and analyzed. The median duration of operation was 285 (range 146-440) min. No patients required blood transfusions. The number of dissected lymph nodes was 32 (range 22-56). There were no intraoperative complications, and no cases were converted to open surgery. All the patients were pT1N0M0 stage IA. No anastomotic leakage or complications were detected. Postoperative gastrography after reconstruction showed that contrast medium flowed mainly to the remnant stomach. The average percentage body weight loss was 14.0 ± 7.1% at 10 months. The average percentage decrease in serum hemoglobin was 5.4 ± 10.4% at 12 months. This novel technique for intracorporeal DTR provided a considerable advantage by the passage of dietary intake to the remnant stomach after LPG.

    Stripped segments of proximal colon (1-6 cm distal to the ampulla caecalis coli) were studied in vitro in Ussing chambers under short-circuit conditions using the pH-stat technique. With glucose and HCO3-CO2 present in the serosal bathing solution only, proximal colon alkalinizes the luminal bathing solution at a rate of 2.1 +/- 0.2 mu eq X h-1 X cm-2 (n = 36). With HCO3-CO2 present in the luminal bathing solution alone, proximal colon does not significantly acidify or alkalinize the serosal bathing solution. Addition of glucose (10 mM) to the luminal bathing solution abolished luminal alkalinization. Removal of HCO3 and CO2 from the serosal bathing solution or replacement of O2 with N2 also abolished luminal alkalinization. Acetazolamide (0.1 mM) added to both bathing solutions did not alter the rate of luminal alkalinization. Ion-replacement studies revealed that the alkalinization process was highly dependent on the presence of Na in the bathing solutions and much less dependent on the presence of Cl. Furthermore, ouabain (0.1 mM) significantly reduced luminal alkalinization. As in rabbit ileum, serosal epinephrine (0.1 mM) did not alter luminal alkalinization but increased serosal alkalinization by a Na-dependent mechanism. These results suggest that luminal alkalinization results from a Na-dependent, active transcellular HCO3 transport process and that a Na-dependent HCO3 absorptive process is activated by adrenergic stimuli.

    Full Text Available Impacted valgus fractures of the proximal humerus are considered to be a special type fracture, since impaction of the humeral head on the metaphysis with maintenance of the posteromedial periosteum improves the prognosis regarding occurrences of avascular necrosis. This characteristic can also facilitate the reduction maneuver and increase the consolidation rate of these fractures, even in more complex cases. The studies included were obtained by searching the Bireme, Medline, PubMed, Cochrane Library and Google Scholar databases for those published between 1991 and 2013. The objective of this study was to identify the most common definitions, classifications and treatment methods used for these fractures in the orthopedic medical literature.

    Chronic flexion contracture of the proximal interphalangeal (PIP) joint presents a common yet challenging problem to hand surgeons. Over the years, multiple treatment modalities have been described for this problem, producing limited results. Nonoperative treatment using serial casting and splints should be tried before attempting open surgical release, which should be done in selected patients. The use of external fixation for treating PIP contracture has been encouraging and can be a useful alterative. This review provides an update on the current management of PIP joint contractures and presents a flowchart of treatment to aid decision making.

    2014-01-01

    Urea transport in the proximal tubule is passive and is dependent on the epithelial permeability. The present study examined the maturation of urea permeability (Purea) in in vitro perfused proximal convoluted tubules (PCT) and basolateral membrane vesicles (BLMV) from rabbit renal cortex. Urea transport was lower in neonatal than adult PCT at both 37 and 25°C. The PCT Purea was also lower in the neonates than the adults (37°C: 45.4 ± 10.8 vs. 88.5 ± 15.2 × 10−6 cm/s, P 0.05). The activation energy for PCT Purea was not different between the neonatal and adult groups. BLMV Purea was determined by measuring vesicle shrinkage, due to efflux of urea, using a stop-flow instrument. Neonatal BLMV Purea was not different from adult BLMV Purea at 37°C [1.14 ± 0.05 × 10−6 vs. 1.25 ± 0.05 × 10−6 cm/s; P = not significant (NS)] or 25°C (0.94 ± 0.06 vs. 1.05 ± 0.10 × 10−6 cm/s; P = NS). There was no effect of 250 μM phloretin, an inhibitor of the urea transporter, on Purea in either adult or neonatal BLMV. The activation energy for urea diffusion was also identical in the neonatal and adult BLMV. These findings in the BLMV are in contrast to the brush-border membrane vesicles (BBMV) where we have previously demonstrated that urea transport is lower in the neonate than the adult. Urea transport is lower in the neonatal proximal tubule than the adult. This is due to a lower rate of apical membrane urea transport, whereas basolateral urea transport is the same in neonates and adults. The lower Purea in neonatal proximal tubules may play a role in overall urea excretion and in developing and maintaining a high medullary urea concentration and thus in the ability to concentrate the urine during renal maturation.

    Research indicates that higher levels of traffic-related pollution exposure increase the risk of diabetes, but the association between road proximity and diabetes risk remains unclear. To assess and quantify the association between residential proximity to major roadways and type 2 diabetes, a systematic review and meta-analysis was performed. Embase, Medline, and Web of Science were searched for eligible studies. Using a random-effects meta-analysis, the summary relative risks (RRs) were calculated. Bayesian meta-analysis was also performed. Eight studies (6 cohort and 2 cross-sectional) with 158,576 participants were finally included. The summary unadjusted RR for type 2 diabetes associated with residential proximity to major roadways was 1.24 (95% confidence interval [CI]: 1.07-1.44, p = 0.001, I² = 48.1%). The summary adjusted RR of type 2 diabetes associated with residential proximity to major roadways was 1.12 (95% CI: 1.03-1.22, p = 0.01, I² = 17.9%). After excluding two cross-sectional studies, the summary results suggested that residential proximity to major roadways could increase type 2 diabetes risk (Adjusted RR = 1.13; 95% CI: 1.02-1.27, p = 0.025, I² = 36.6%). Bayesian meta-analysis showed that the unadjusted RR and adjusted RR of type 2 diabetes associated with residential proximity to major roadways were 1.22 (95% credibility interval: 1.06-1.55) and 1.13 (95% credibility interval: 1.01-1.31), respectively. The meta-analysis suggested that residential proximity to major roadways could significantly increase risk of type 2 diabetes, and it is an independent risk factor of type 2 diabetes. More well-designed studies are needed to further strengthen the evidence.

    Green, C L; Frommer, M

    2001-08-01

    Representatives of five distinct types of transposable elements of the mariner family were detected in the genomes of the Queensland fruit fly Bactrocera tryoni and its sibling species Bactrocera neohumeralis by phylogenetic analysis of transposase gene fragments. Three mariner types were also found in an additional tephritid, Bactrocera jarvisi. Using genomic library screening and inverse PCR, full-length elements representing the mellifera subfamily (B. tryoni.mar1) and the irritans subfamily (B. tryoni.mar2) were isolated from the B. tryoni genome. Nucleotide consensus sequences for each type were derived from multiple defective copies. Predicted transposase sequences share approximately 23% amino acid identity. B. tryoni.mar1 elements have an estimated copy number of about 900 in the B. tryoni genome, whereas B. tryoni.mar2 element types appear to be present in low copy number.

    The electroantennogram method was used to investigate the number of distinct olfactory receptor neuron types responding to a range of behaviorally active volatile chemicals in gravid Queensland fruit flies, Bactrocera tryoni. Three receptor neuron types were identified. One type responds to methyl butyrate, 2-butanone, farnesene, and carbon dioxide; a second to ethanol; and a third to n-butyric acid and ammonia. The receptor neuron type responding to methyl butyrate, 2-butanone, farnesene, and carbon dioxide consists of three subtypes. The presence of a limited number of receptor neuron types responding to a diverse set of chemicals and the reception of carbon dioxide by a receptor neuron type that responds to other odorants are novel aspects of the peripheral olfactory discrimination process.

    Full Text Available A foundation for a DNA barcode reference library for the tropical plants of Australia is presented here. A total of 1572 DNA barcode sequences are compiled from 848 tropical Queensland species. The dataset represents 35% of the total flora of Queensland’s Wet Tropics Bioregion, 57% of its tree species and 28% of the shrub species. For approximately half of the sampled species, we investigated the occurrence of infraspecific molecular variation in DNA barcode loci rbcLa, matK, and the trnH-psbA intergenic spacer region across previously recognized biogeographic barriers. We found preliminary support for the notion that DNA barcode reference libraries can be used as a tool for inferring biogeographic patterns at regional scales. It is expected that this dataset will find applications in taxonomic, ecological, and applied conservation research.

  9. An empirical model of water quality for use in rapid management strategy evaluation in Southeast Queensland, Australia.

    2012-04-01

    Simulation models have been widely adopted in fisheries for management strategy evaluation (MSE). However, in catchment management of water quality, MSE is hampered by the complexity of both decision space and the hydrological process models. Empirical models based on monitoring data provide a feasible alternative to process models; they run much faster and, by conditioning on data, they can simulate realistic responses to management actions. Using 10 years of water quality indicators from Queensland, Australia, we built an empirical model suitable for rapid MSE that reproduces the water quality variables' mean and covariance structure, adjusts the expected indicators through local management effects, and propagates effects downstream by capturing inter-site regression relationships. Empirical models enable managers to search the space of possible strategies using rapid assessment. They provide not only realistic responses in water quality indicators but also variability in those indicators, allowing managers to assess strategies in an uncertain world.

    Four species of the genus Platynectes subgenus Gueorguievtes Vazirani, 1976 are described from Queensland, Australia: Platynectes brancuccii sp. n. (Atherton Tableland), P. larsoni sp. n. (Mulgrave Range and Windsor Tableland), P. ponderi sp. n. (Carnarvon Range) and Platynectes weiri sp. n. (White Mountains National Park and Hope Vale Mission). The latter two are the first species of the genus with striae on elytra and the informal P. weiri-species group is established for them. Platynectes brancuccii sp. n. and P. larsoni sp. n. belong to the P. decempunctatus-species group. All four species were collected from small rain forest streams or rest pools of intermittent creeks. Important species characters (median lobes, parameres and colour patterns) of all species are figured, and notes on their distribution and ecology are given. Altogether 17 species of the genus are now known from Australia.

    Full Text Available This paper analyses the general trends of online purchasing in Central Queensland (CQ communities during 1999-2002 and identifies the socio-economic factors affecting online purchasing activities. The Online Purchasing Indicator, defined as a combination of percentages of online purchasers and of regular purchasers (>one item/month within a group, is applied to compare these activities between these two groups. The study identifies that four factors, namely ‘personal attributes’, ‘knowledge’, ‘trust’ and ‘need’ may play important roles in online purchasing decisions. The research found that regional economic bleeding associated with low local adoption failing to provide justification for local business to adopt electronic purchasing support has not yet reached significant levels.

    The objective of this study was to apply a quality improvement collaborative to increase the number of physical health assessments conducted with consumers diagnosed with schizophrenia in adult community mental health services across Queensland. Sixteen adult mental health service organisations voluntarily took part in the statewide collaborative initiative to increase the number of physical health assessments completed on persons with a diagnosis of schizophrenia spectrum disorders managed through the community mental health service. Improvement in the physical health assessment clinical indicator was demonstrated across the state over a 3-year period with an increase in the number of physical health assessments recorded from 12% to 58%. Significant improvements were made over a 3-year period by all mental health services involved in the collaborative, supporting the application of a quality improvement methodology to drive change across mental health services. © The Royal Australian and New Zealand College of Psychiatrists 2015.

    Gai, Wei

    PETS (Proximity Effect Tunneling Spectroscopy) technique has been applied to Niobium/Yttrium and Niobium/Lutetium bilayers. We have determined electron - phonon interaction parameter lambda_{rm e -ph} is 0.55 for Yttrium and 0.67 for Lutetium. Spin fluctuations parameter lambda_{ rm S} is 0.20 for Yttrium and 0.33 for Lutetium. We found that the large spin fluctuations in Yttrium and Lutetium has responsibility to the absence of superconductivity in them. Our results have given a reasonable explanation of high superconducting transition temperature in them under high pressure. The large reflection coefficient and strong diffuse scattering at Nb/Y and Nb/Lu interface has been discovered and it should have strong influence on the transport properties of metallic superlattices. From the modeling study of elastic scattering in proximity effect tunnel junctions, we have explained why some conventional made high {rm T_{C}} superconducting tunnel junctions give ideal like characteristics in the gap region but variable strength phonon structures in the phonon region.

    While cilia are recognized as important signaling organelles, the extent of ciliary functions remains unknown because of difficulties in cataloguing proteins from mammalian primary cilia. We present a method that readily captures rapid snapshots of the ciliary proteome by selectively biotinylating ciliary proteins using a cilia-targeted proximity labeling enzyme (cilia-APEX). Besides identifying known ciliary proteins, cilia-APEX uncovered several ciliary signaling molecules. The kinases PKA, AMPK, and LKB1 were validated as bona fide ciliary proteins and PKA was found to regulate Hedgehog signaling in primary cilia. Furthermore, proteomics profiling of Ift27/Bbs19 mutant cilia correctly detected BBSome accumulation inside Ift27(-/-) cilia and revealed that β-arrestin 2 and the viral receptor CAR are candidate cargoes of the BBSome. This work demonstrates that proximity labeling can be applied to proteomics of non-membrane-enclosed organelles and suggests that proteomics profiling of cilia will enable a rapid and powerful characterization of ciliopathies.

  15. Empathy: Its ultimate and proximate bases.

    There is disagreement in the literature about the exact nature of the phenomenon of empathy. There are emotional, cognitive, and conditioning views, applying in varying degrees across species. An adequate description of the ultimate and proximate mechanism can integrate these views. Proximately, the perception of an object's state activates the subject's corresponding representations, which in turn activate somatic and autonomic responses. This mechanism supports basic behaviors (e.g., alarm, social facilitation, vicariousness of emotions, mother-infant responsiveness, and the modeling of competitors and predators) that are crucial for the reproductive success of animals living in groups. The Perception-Action Model (PAM), together with an understanding of how representations change with experience, can explain the major empirical effects in the literature (similarity, familiarity, past experience, explicit teaching, and salience). It can also predict a variety of empathy disorders. The interaction between the PAM and prefrontal functioning can also explain different levels of empathy across species and age groups. This view can advance our evolutionary understanding of empathy beyond inclusive fitness and reciprocal altruism and can explain different levels of empathy across individuals, species, stages of development, and situations.

    The purpose of this study was to examine the results of the proximal femoral osteotomy for the management of hip deformity in 32 children, aged 4 to 15 years. Twenty-two bilateral and ten unilateral procedures were performed. The indications for surgery were subluxation in 16, dislocation in two, and intoeing and femoral anteversion in 14. The average follow-up was two years and 11 months. CE angle of Wiberg, acetabular index and neck shaft angle were evaluated. The average time to regain preoperative ambulatory status was six months with intensive physical therapy. In osteotomies performed for subluxation, dislocation did not occur; roentgenographic indices showed variability in the degree of subluxation. Osteotomy performed in children older than 8 years of age produced no evidence of acetabular remodeling. THere was no recurrence with osteotomies for dislocation. In those patients with internal rotation gait, improvement resulted. Complications were few and minor. Hip dislocation in children with progressive subluxation, in spite of previous soft-tissue releases, is preventable by proximal femoral osteotomy. The inability of the roentgenographic indices to quantitate the increased stability indicates the procedure's major effect is to realign muscle forces about the hip. Treatment of the intoeing gait produced improvement of rotational deformity.

    Automated spacecraft docking operations are being performed using a full scale motion based simulator and an optical sensor. This presentation will discuss the work in progress at TRW and MSFC facilities to study the problem of automated proximity and docking operations. The docking sensor used in the MSFC Optical Sensor and simulation runs are performed using the MSFC Flat Floor Facility. The control algorithms and six degrees of freedom (6DOF) simulation software were developed at TRW and integrated into the MSFC facility. Key issues being studied are the quantification of docking sensor requirements and operational constraints necessary to perform automated docking maneuvers, control algorithms capable of performing automated docking in the presence of sensitive and noisy sensor data, and sensor technologies for automated proximity and docking operations. As part of this study the MSFC sensor characteristics were analyzed and modeled so that off line simulation runs can be performed for control algorithm testing. Our goal is to develop and demonstrate full 6DOF docking capabilities with actual sensors on the MSFC motion based simulator. We present findings from actual docking simulation runs which show sensor and control loop performance as well as problem areas which require close attention. The evolution of various control algorithms using both phase plane and Clohessy-Wiltshire techniques are discussed. In addition, 6DOF target acquisition and control strategies are described.

    To document albuminuria prevalence and its associated factors in Aboriginal and Torres Strait Islander (TSI) adults with high renal and metabolic risks from 19 rural and remote north Queensland communities. One thousand nine hundred seventy-one indigenous adults were enrolled in 1998 and 566 completed follow up in 2007 in this population-based study. Measurements included weight, waist circumference (WC), blood pressure (BP), fasting glucose, lipids, gamma-glutamyltransferase (GGT), urinary albumin creatinine ratio (UACR), smoking, alcohol intake and physical activity (PA). Albuminuria was defined as an UACR > =2.5 g/mol in males and > =3.5 g/mol in females. The association between albuminuria and biomedical factors was assessed with generalised linear modelling. Baseline albuminuria prevalence was 19.7 % (95 % CI: 18.0-21.6 %). Follow up prevalence was 42.4 % (95 % CI: 38.4-46.5 %) among the 566 adults having the 2(nd) UACR measurements. Follow-up albuminuria was associated with fasting glucose of 5.4 mmol/L (OR 2.5, 95 % CI 1.5-4.2), GGT tertiles in a dose-response manner (OR 2.0 for 2(nd) and 3.7 for 3(rd) tertile, p for trend albuminuria compared to TSI counterparts, while TSI smokers had twice the likelihood (95 % CI 1.2-3.2). At both baseline and follow up, albuminuria was more prevalent among older participants. Indigenous Australians in north Queensland are at high risk of albuminuria. Overweight and obesity, glycaemia, increased GGT, and smoking were associated with albuminuria at baseline and/or follow up.

    Hypertension and other chronic disease risks are common among Aboriginal and Torres Strait Islander adults but there is little evidence regarding the epidemiology of these risk factors during adolescence. This study examines the prevalence of pre-hypertension, hypertension and other cardiovascular risk factors in Aboriginal and Torres Strait Islander people aged 15-24 years living in remote Indigenous communities in north Queensland. In so doing, it aims to better inform the approach to cardiovascular disease in this population. This is a descriptive study that retrospectively examines health service data from a program of community screening, the Young Persons Check (YPC). Participants were 1,883 Aboriginal and Torres Strait Islander people aged 15-24 years who attended for a YPC in 11 remote communities in north Queensland between March 2009 and April 2011. Overall, the prevalence of pre-hypertension was 34.0%; stage I hypertension was 17.7% and stage II hypertension was 3.3%. The prevalence of elevated waist circumference was 47.6%, overweight or obesity 45.9%, elevated triglycerides 18.3%, decreased HDL 54.8% and proteinuria 24.3%. The prevalence of hypertension (stage I or II) among Torres Strait Islander males was 34.1%, Aboriginal males 26.9%, Torres Strait Islander females 12.6% and Aboriginal females 13.0%. Hypertension was associated with sex (males) (OR= 4.37, pobesity (OR=4.59, phypertension, hypertension and other cardiovascular risk in this population is highly prevalent. Hypertension was particularly prevalent among male participants. The results reiterate the importance of early life experience in cardiovascular disease prevention. © 2015 The Authors.

    Overweight and obesity are major risk factors for chronic disease. Physical activity plays an important role in increasing wellbeing and reducing weight. General practitioners' advice and intervention can help patients increase their physical activity. This pilot study is part of a larger study investigating physical activity opportunities in rural Queensland. A survey was sent to a random sample of 40 general practices in rural Queensland. The survey asked GPs about strategies they use when dealing with patients who would benefit from exercise, their use of Lifescripts, the main perceived barriers to exercise in their location, perceptions on change in exercise patterns over 5 years, and local resources and referral networks available in their location. The data was analysed using a five stage framework and coded into themes. A total of 67.5% of practices responded. The primary strategy GP respondents used to address overweight was discussion and advice. Fifteen of the 27 respondents referred patients to allied health professionals and local sport/recreation organisations. Lack of physical and human resources to encourage and support weight loss was the main perceived barrier to helping patients achieve physical activity and weight loss goals. Behavioural factors are globally acknowledged as the biggest barriers to exercise. The GPs surveyed recognise that, for most people, external support is essential for ongoing exercise compliance and motivation. This can be in the form of discussion with, and advice from, the GP, or referral to gyms or other services. Respondents identified limited facilities and support in rural areas as barriers. Formalisation of referral pathways and follow up is currently lacking and could assist rural GPs in helping their patients to exercise and lose weight.
