    2002-01-01

    Raging brush fires are threatening the suburbs of Sydney, Australia, in the waning days of 2001. Lightning strikes started some of the fires in mid-December, but arsonists may have started more. So far the flames have damaged Blue Mountain and Royal National Parks, threatening the wildlife there. More than 100 homes in suburban Sydney have also been destroyed. The image above shows the fires on December 25, 2001, when smoke and haze covered the city of Sydney. The scene was acquired by the Moderate-resolution Imaging Spectroradiometer (MODIS) aboard NASA's Terra satellite.

    Sydney is Australia's oldest city being founded in 1788. The city was fortunate to be established on an extensive and a relatively undeformed layer of lithified quartz sandstone of Triassic age that has proved to be an ideal building stone. The stone has been long identified by geologists as the Hawkesbury Sandstone. On the other hand the term "Sydney sandstone" has also been widely used over a long period, even to the extent of being utilised as the title of published books, so its formal designation as a heritage stone will immediately formalise this term. The oldest international usage is believed to be its use in the construction of the Stone Store at Kerikeri, New Zealand (1832-1836). In the late 19th century, public buildings such as hospitals, court houses as well as the prominent Sydney Town Hall, Sydney General Post Office, Art Gallery of New South Wales, State Library of New South Wales as well as numerous schools, churches, office building buildings, University, hotels, houses, retaining walls were all constructed using Sydney sandstone. Innumerable sculptures utilising the gold-coloured stone also embellished the city ranging from decorative friezes and capitals on building to significant monuments. Also in the late 19th and early 20th century, Sydney sandstone was used for major construction in most other major Australian cities especially Melbourne, Adelaide and Brisbane to the extent that complaints were expressed that suitable local stone materials were being neglected. Quarrying of Sydney sandstone continues today. In 2000 it was recorded noted that there were 33 significant operating Sydney sandstone quarries including aggregate and dimension stone operations. In addition sandstone continues to be sourced today from construction sites across the city area. Today major dimension stone producers (eg Gosford Quarries) sell Sydney sandstone not only into the Sydney market but also on national and international markets as cladding and paving products as well as block. Recent international projects by Gosford Quarries include Mishima Golf Club in Japan, Al Awadi Tower in Kuwait, New World Resort in China and a Hard Rock Café in Florida, USA. Arguably Sydney sandstone is Australia's most prominent potential Global Heritage Stone Resource and details are readily available in existing publications to make the nomination.

    This spaceborne radar image is dominated by the metropolitan area of Australia's largest city, Sydney. Sydney Harbour, with numerous coves and inlets, is seen in the upper center of the image, and the roughly circular Botany Bay is shown in the lower right. The downtown business district of Sydney appears as a bright white area just above the center of the image. The Sydney Harbour Bridge is a white line adjacent to the downtown district. The well-known Sydney Opera House is the small, white dot to the right of the bridge. Urban areas appear yellow, blue and brown. The purple areas are undeveloped areas and park lands. Manly, the famous surfing beach, is shown in yellow at the top center of the image. Runways from the Sydney Airport are the dark features that extend into Botany Bay in the lower right. Botany Bay is the site where Captain James Cook first landed his ship, Endeavour, in 1770. The image was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR) on April 20, 1994, onboard the space shuttle Endeavour. The area shown is 33 kilometers by 38kilometers (20 miles by 23 miles) and is centered at 33.9 degrees south latitude, 151.2 degrees east longitude. North is toward the upper left. The colors are assigned to different radar frequenciesand polarizations as follows: red is L-band, vertically transmittedand horizontally received; green is C-band, vertically transmitted and horizontally received; and blue is C-band, vertically transmittedand received. SIR-C/X-SAR, a joint mission of the German, Italianand United States space agencies, is part of NASA's Mission to Planet Earth. #####

    Among industrialised countries, fine particle (PM2.5) and ozone levels in the Sydney metropolitan area of Australia are relatively low. Annual mean PM2.5 levels have historically remained below 8?g/m(3) while warm season (November-March) ozone levels occasionally exceed the Australian guideline value of 0.10ppm (daily 1h max). Yet, these levels are still below those seen in the United States and Europe. This analysis focuses on two related questions: (1) what is the public health burden associated with air pollution in Sydney; and (2) to what extent would reducing air pollution reduce the number of hospital admissions, premature deaths and number of years of life lost (YLL)? We addressed these questions by applying a damage function approach to Sydney population, health, PM2.5 and ozone data for 2007 within the BenMAP-CE software tool to estimate health impacts and economic benefits. We found that 430 premature deaths (90% CI: 310-540) and 5800 YLL (95% CI: 3900-7600) are attributable to 2007 levels of PM2.5 (about 2% of total deaths and 1.8% of YLL in 2007). We also estimate about 630 (95% CI: 410-840) respiratory and cardiovascular hospital admissions attributable to 2007 PM2.5 and ozone exposures. Reducing air pollution levels by even a small amount will yield a range of health benefits. Reducing 2007 PM2.5 exposure in Sydney by 10% would, over 10 years, result in about 650 (95% CI: 430-850) fewer premature deaths, a gain of 3500 (95% CI: 2300-4600) life-years and about 700 (95% CI: 450-930) fewer respiratory and cardiovascular hospital visits. These results suggest that substantial health benefits are attainable in Sydney with even modest reductions in air pollution. PMID:26414085

    The toxicological responses of three species to 103 surficial saltwater sediment samples from Sydney Harbour, and coastal lakes and estuaries on the south-east coast of New South Wales, Australia, were tested in a battery of four to six laboratory toxicity tests. This is the first large-scale toxicological study of sediments in Australia, the objective of which is to assess the protective and predictive abilities of North American biological effects-based sediment quality guidelines, recently adopted in Australia. Amphipods were exposed to whole sediments in survival and reburial tests, sea urchin fertilisation and larval development tests were conducted on porewaters, and bacterial bio-luminescence (Microtox) tests were conducted on organic solvent extracts and porewaters. Local indigenous species were used for the amphipod and sea urchin tests (Corophium sp. and Heliocidaris tuberculata, respectively). A wide range of responses, from <25 to 100% of negative controls were observed in all tests. Mean control-adjusted responses ranged from 46 to 96% for all tests. The percentages of highly toxic samples ranged from 11 to 83% in the various tests. The order of test sensitivity was: amphipod survival < Microtox test of porewaters < amphipod reburial < sea urchin larval development < sea urchin fertilisation < Microtox test of solvent extracts. Concordance between toxicity tests in classifying samples as highly toxic or not, ranged from 47 to 79%, indicating some similarities between test results, but not complete equivalence. Combined toxicity test results showed that the incidence of highly toxic responses occurring in the majority of tests (75-100% of tests) was low (5% of samples), but a large percentage of samples had highly toxic results in at least one test (76% of samples). Toxicity was more pervasive in the Sydney region than in coastal lakes and estuaries south of Sydney. The current study demonstrated the utility of indigenous invertebrate species and the Microtox bacterium in a sediment toxicity test battery for Australian saltwater sediments. PMID:15327149

    This image from MISR's nadir-looking camera was acquired on July 11, 2000 (Terra orbit 3009) and shows a 200-kilometer section of the eastern Australian coast, centered around the Sydney metropolitan area. This city is host to the 2000 Olympics Games, which open Friday, September 15. Sydney Harbour is the rugged-shaped inlet toward the northern side of the grey-colored central city area. Olympic Park, the main venue for the Games, is on a southern arm of the harbor, about 20 kilometers from the coast.

    The areas to the north, west, and south of Sydney are characterized by rugged terrain and extensive forests. Just north of the city the Ku-ring-gai Chase and Brisbane Waters National Parks surround the Hawkesbury River estuary. Further north and separated from the ocean by narrow dunes are a series of lakes, the two largest in this image being Lake Macquarie (at the top) and Tuggerah Lake.

    West of the metropolitan area, some 65 kilometers inland, are the Blue Mountains. The primary transport corridor for road and rail across the mountains is clearly visible, and just north of it is the steep-sided Grose River valley. In the southern part of the mountains is a series of long valleys filled by Lake Burragorang, a major source of Sydney's water supply.

    South of Sydney's central area are Botany Bay, Bate Bay and Port Hacking, and the Royal National Park. Further south, the forested coastline gives way to the city of Wollongong, the adjacent steel-making complex at Port Kembla, and Lake Illawarra.

    MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.

    There is limited information on the causes of paediatric diarrhoea in Sydney. This cross-sectional study used clinical and microbiological data to describe the clinical features and pathogens associated with gastrointestinal illnesses for children presenting to two major public hospitals in Sydney with diarrhoea, for the period January 2007-December 2010. Of 825 children who tested positive for an enteric pathogen, 430 medical records were reviewed. Adenovirus, norovirus and rotavirus were identified in 20.8%, 20.3% and 21.6% of reviewed cases, respectively. Younger children were more likely to have adenovirus and norovirus compared with rotavirus (P=0.001). More viruses were detected in winter than in the other three seasons (P=0.001). Rotavirus presented a distinct seasonal pattern with the lowest rates occurring in the warm months and peaking in the cooler months. Adenovirus showed a less consistent monthly trend, and norovirus detection increased in the cooler months (P=0.008). A decline in the number of rotavirus cases was observed after mid-2008. The majority of childhood diarrhoeal illnesses leading to hospital presentations in Sydney are caused by enteric viruses with most infections following clear seasonal patterns. However, a sustained decrease in the incidence of rotavirus infections has been observed over the study period. PMID:23856534

    2002-01-01

    Smoke obscures much of the landscape near Sydney, Australia, in the true-color image above (top). However, the areas with active fires are revealed by the false-color image (bottom), which was made using shortwave infrared data that are sensitive to heat and provide the ability to 'see' through smoke. In the bottom scene, the black areas show fresh burn scars, while greens show landscape untouched by fire. Apparently, the fire burned up to the edge of a road (the thin black line snaking from the lefthand side of the image and disappearing off the bottom) and was unable to jump across. The thick dark line along the bottom of the scene is a river. Both images were made using data acquired on December 28, 2001, by the Advanced Land Imager (ALI), flying aboard NASA's Earth Observing-1 (EO-1) satellite.

    Interior and exterior dust, soil and paint were analysed at five brick urban Sydney homes over 15 months to evaluate temporal variations and discriminate sources of lead (Pb) exposure. Exterior dust gauge Pb loading rates (?g/m(2)/28 days), interior vacuum dust Pb concentrations (mg/kg) and interior petri-dish Pb loading rates (?g/m(2)/28 days), were correlated positively with soil Pb concentrations. Exterior dust gauge Pb loading rates and interior vacuum dust Pb concentrations peaked in the summer. Lead isotope and Pb speciation (XAS) were analysed in soil and vacuum dust samples from three of the five houses that had elevated Pb concentrations. Results show that the source of interior dust lead was primarily from soil in two of the three houses and from soil and Pb paint in the third home. IEUBK child blood Pb modelling predicts that children's blood Pb levels could exceed 5 ?g/dL in two of the five houses. PMID:24071634

    To investigate potential high organisational level impacts of persistent organic pollution in the wetlands in the Sydney Olympic Park (SOP) remediated site, the benthic macroinvertebrate assemblages of seven wetlands within SOP and two off-site reference wetlands were examined. Sediment cores were collected, stained and preserved from each study site and the macroinvertebrates identified to the appropriate taxonomic level (Class, Order, Family, Subfamily). Data were analysed for taxon richness and macroinvertebrate abundance and multivariate techniques were used to identify chemical/physical characteristics of the sediment, which were important influences on the differences in the assemblage between study sites. Macroinvertebrate abundance was highly variable between study sites and taxon richness was low across all sites. Oligochaetes, nematodes, ostracods and chironomids were the most common taxa found and were the most important in influencing differences between the macroinvertebrate assemblages among the study sites. Sediment grain size and chemical characteristics of the sediments (?PAH, ?PCB, TCDDeq and heavy metal concentrations) were important in separating the study sites based on taxon richness and abundance. Canonical correspondence analysis separated the macroinvertebrate assemblages at newly two created wetlands from those at other study sites including the urban reference sites. Increased sediment POP contamination (particularly as measured TCDDeq and ?DDT concentrations) is a likely contributor in excluding pollution sensitive taxa and, therefore, alterations to benthic macroinvertebrate assemblages. Further, the influence of TOC suggests the significance of catchment inputs in contributing to changes in macroinvertebrate assemblage. The SOP remediation led to the establishment of wetlands with benthic communities representative of those expected in urban wetlands. PMID:20857194

    This paper presents the first historical data on the occurrence of polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCDs) in estuarine sediment from Australia. Sediment cores and surficial sediment samples were collected from four locations within Sydney estuary, Australia. Large increases in concentrations were observed for all compounds between 1980 and 2014, especially for BDE-209 (representative usage of Deca-BDE commercial mixture), which was found in surficial sediment at an average concentration of 42 ng/g dry wt (21-65 ng/g dry wt). PBDE congeners representative of both the Penta- and Octa-BDE commercial mixtures (?6PBDEs) were also found in their highest concentrations in surficial sediments (average: 1.3 ng/g dry wt; range: 0.65-2.5 ng/g dry wt). PBDE concentrations in surficial sediments were relatively high when compared with those presented in the available literature. This suggests that their input into the Sydney estuary has not decreased since their bans almost a decade earlier. After a sharp increase in the 1990s, HBCD concentrations peaked at an average of 3.5 ng/g dry wt (1.8-5.3 ng/g dry wt) in surficial samples. With global legislation on HBCDs allowing its usage for the next 10 years, it is expected that its input into the estuary is likely to continue. PMID:25617997

    Azithromycin has shown high efficacy in randomized trials when used for treating infectious syphilis in Africa. However, its use in clinical practice has been limited by the development of antimicrobial drug resistance. Resistance has not previously been reported from Australasia. The aim of this study was to determine the prevalence of and risk factors for azithromycin-resistant syphilis-causing strains in Sydney, Australia. We evaluated 409 samples that were PCR positive for Treponema pallidum DNA collected between 2004 and 2011 for the presence of the A2058G mutation, which confers resistance to macrolide antibiotics such as azithromycin. Overall, 84% of samples harbored the mutation. The prevalence of the mutation increased during the study period (P trend, 0.003). We also collected clinical and demographic data on 220 patients from whom these samples had been collected to determine factors associated with the A2058G mutation; 97% were from men who have sex with men. Reporting sex in countries other than Australia was associated with less macrolide resistance (adjusted odds ratio, 0.25; 95% confidence interval, 0.09 to 0.66; P = 0.005), with other study factors showing no association (age, HIV status, recent macrolide use, stage of syphilis, or history of prior syphilis). Azithromycin cannot be recommended as an alternative treatment for syphilis in Sydney. PMID:24850356

    2015-06-01

    Sydney estuary (Australia), like many urbanised waterways, is degraded due to an extended history of anthropogenic activity. Two major sources of contamination to this estuary are discharge by former shoreline industries and historic and contemporary catchment stormwater. The objectives of the present study were to document changes in shoreline land use from European settlement to the present day and determine the influence of this trend on the metal content of adjacent estuarine sediments. Temporal analysis of land use for seven time horizons between 1788 and 2010 showed rapid expansion of industry along much of the Sydney estuary foreshore soon after European settlement due to the benefits of easy and inexpensive access and readily available water for cooling and power. Shoreline industry attained maximum development in 1978 (32-km length) and declined rapidly to the present-day (9-km length) through redevelopment of industrial sites into medium- to high-density, high-value residential housing. Cores taken adjacent to 11 long-term industrial sites showed that past industrial practices contributed significantly to contamination of estuarine sediment. Subsurface metal concentrations were up to 35 times that of present-day surface sediment and over 100 times greater than natural background concentrations. Sedimentation rates for areas adjacent to shoreline industry were between 0.6 and 2.5 cm/year, and relaxation times were estimated at 50 to 100 years. Natural relaxation and non-disturbance of sediments may be the best management practice in most locations. PMID:25937494

    OBJECTIVES: This study examined the effects of outdoor air pollutants on daily hospital admissions in Sydney, Australia. METHODS: A time-series analysis of counts of daily hospital admissions and outdoor air pollutants (1990 to 1994) was performed, by means of Poisson regression that allowed for overdispersion and autocorrelation. RESULTS: An increase in daily maximum 1-hour concentration of nitrogen dioxide from the 10th to the 90th percentile was associated with an increase of 5.29% (95% confidence interval = 1.07, 9.68) in childhood asthma admissions and 4.60%(-0.17,9.61) in chronic obstructive pulmonary disease (COPD) admissions. A similar increase in daily maximum 1-hour particulate concentration was associated with an increase of 3.01% (-0.38, 6.52) in COPD admissions. An increase from the 10th to the 90th percentile in daily maximum 1-hour nitrogen dioxide, daily maximum 1-hour ozone, and daily mean particulate was associated with an increase in heart disease admissions among those 65 years and older of 6.71% (4.25, 9.23), 2.45% (-0.37, 5.35), and 2.82% (0.90, 4.77), respectively. Heart disease and childhood asthma were primarily associated with nitrogen dioxide; COPD was associated with both nitrogen dioxide and particulates. CONCLUSIONS: Current levels of air pollution in Sydney are associated with increased hospitalization for respiratory and heart disease. PMID:9842371

    Metal concentrations of the inshore greentail prawn, Metapenaeus bennettae, and surface sediments from locations within Sydney estuary and Port Hacking (Australia) were assessed for bioaccumulation and contamination. The current study aimed to assess metal concentrations in prawn tissue (tail muscle, exoskeleton, hepatopancreas and gills), relate whole body prawn tissue metal concentrations to sediment metal concentrations and animal size, as well as assess prawn consumption as a risk to human health. Metal concentrations were highest in sediment and prawns from contaminated locations (Iron Cove, Hen and Chicken Bay and Lane Cove) in Sydney estuary compared with the reference estuary (Port Hacking). Concentrations in sediments varied considerably between sites and between metals (As, Cd, Cr, Cu, Ni, Pb and Zn), and although concentrations exceeded Interim Sediment Quality Guideline-Low values, metals (As, Cd, Cr, Cu, Ni, Pb and Zn) were below Australian National Health and Medical Research Council human consumption guidelines in prawn tail muscle tissue. Metal concentrations in prawn tail muscle tissue were significantly different (p???0.05) amongst locations for Pb, Zn and Cd, and metal concentrations were generally highest in gills tissue, followed by the hepatopancreas, exoskeleton and tail muscle. The exoskeleton contained the highest Sr concentration; the hepatopancreas contained the highest As, Cu and Mo concentrations; and the gills contained the highest Al, Cr, Fe and Pb concentrations. Concentrations of Pb, As and Sr were significantly different (p???0.05) between size groups amongst locations. PMID:23852467

  5. Representations of cycling in metropolitan newspapers - changes over time and differences between Sydney and Melbourne, Australia

    PubMed Central

    2010-01-01

    Background Cycling is important for health, transport, environmental and economic reasons. Newspaper reporting of cycling reflects and can influence public and policy maker attitudes towards resource allocation for cycling and cycling infrastructure, yet such coverage has not been systematically examined. Methods The Factiva electronic news archive was searched for articles referring to cycling published in four major metropolitan newspapers - two in Sydney and two in Melbourne, Australia, in the years from 1998 until 2008. After excluding articles not about cycling, there were 61 articles published in 1998, 45 in 1999, 51 in 2003, 82 in 2007 and 87 in 2008. Each article was coded for positive or negative orientation, and for framing of cyclists and cycling. Inter-rater reliability was calculated on a sample of 30 articles. Results Over the past decade there has been an increase in the reporting of cycling in the major newspapers in Sydney and Melbourne (from 106 in 1998/99 to 169 stories in 2007/08), with a significant increase in reporting of cycling in Melbourne, from 49 to 103 stories (p = 0.04). Recent reporting of cycling was generally positive (47% of articles, compared with 30% of articles which were negative) and focused on benefits such as health and the environment. Three quarters of negative stories involved injury or death of a cyclist. The Sydney based The Daily Telegraph reported the most negative stories (n = 60). We found positive framing of 'cycling' was more widespread than negative, whereas framing of 'cyclists' was more negative than positive. Conclusions Quantity of reporting of cycling varies over time and by newspaper, and even between newspapers in different cities owned by the same media company. News coverage appears to reflect developments in the different cities, with increases in positive reporting of cycling in Melbourne following increases in cycling in that city. Negative cycling newspaper stories may deter people from considering cycling as a transport option, but real physical or political improvements to the cycling environment may be necessary before coverage becomes more positive.

    Correlation analyses between measures of toxicity and concentrations of chemical contaminants were conducted for 103 surficial sediments from Sydney Harbour, Australia, and vicinity. Toxicity tests consisted of amphipod survival and reburial tests of whole sediments (Corophium colo), sea urchin fertilisation and larval development tests of pore waters (Heliocidaris tuberculata) and microbial bioluminescence (Microtox) tests of solvent extracts and pore waters. Toxicity in most tests correlated with concentrations of metallic contaminants, in particular, zinc, lead and copper. Organic contaminants did not correlate as significantly with toxicity. However, Heliocidaris tuberculata showed relationships with organochlorine compounds in samples with low to moderate metals contamination. Toxicity in the Microtox solvent extract test appeared to be primarily influenced by the presence of sulfur. This study has no precedent in Australia and the results support the validity of using local indigenous species in toxicity tests of field-collected sediments. This toxicity/chemistry dataset may be used in evaluations of sediment quality guidelines recently introduced to Australia. PMID:16773229

    Industrial activities and urbanization have had a major consequence for estuarine ecosystem health and water quality globally. Likewise, Sydney estuary has been significantly impacted by widespread, poor industrial practices in the past, and remediation of legacy contaminants have been undertaken in limited parts of this waterway. The objective of the present investigation was to determine the effectiveness of remediation of a former Pb-contaminated industrial site in Homebush Bay on Sydney estuary (Australia) through sampling of inter-tidal sediments and mangrove (Avicennia marina) tissue (fine nutritive roots, pneumatophores, and leaves). Results indicate that since remediation 6 years previously, Pb and other metals (Cu, Ni and Zn) in surficial sediment have increased to concentrations that approach pre-remediation levels and that they were considerably higher than pre-settlement levels (3-30 times), as well as at the reference site. Most metals were compartmentalized in fine nutritive roots with bio-concentration factors greater than unity, while tissues of pneumatophores and leaves contained low metal concentrations. Lead concentrations in fine nutritive root, pneumatophore, and leaf tissue of mangroves from the remediated site were similar to trees in un-remediated sites of the estuary and were substantially higher than plants at the reference site. The situation for Zn in fine nutritive root tissue was similar. The source of the metals was either surface/subsurface water from the catchment or more likely remobilized contaminated sediment from un-remediated parts of Homebush Bay. Results of this study demonstrate the problems facing management in attempting to reduce contamination in small parts of a large impacted area to concentrations below local base level. PMID:25404497

  8. Use of groundwater temperature data in geothermal exploration: the example of Sydney Basin, Australia

    Multidimensional simulations in geothermal exploration require vast quantities of measurements, including temperature, to produce realistic estimates. In Australia, the database of temperature measurements is small, limited by sparse distribution and tainted by non-equilibrium conditions. Groundwater temperature data from the groundwater-monitoring/water-supply bore network provide a creative cost effective way to bridge the information gap. Down-hole temperature profiles are valuable when thermal equilibrium conditions are present. Equilibrium conditions are common in groundwater bores as they are installed to be long term. Effective use of groundwater temperature data for geothermal exploration requires an understanding of (1) the thermal conditions being measured, (2) the factors that affect the measurement, and (3) how the measurements can be used. Highly constrained models, rather than extrapolation maps, are the cost effective, risk-reducing solution for geothermal exploration in Australia. The Sydney Basin provides a case study of how an undervalued, `cold' coal-bearing sedimentary basin became `hot' through high-resolution modelling using groundwater temperature measurements. Groundwater temperature data are the new information source capable of filling the gaps left by the limited deep temperature measurements. Hydrogeological data play a critical role in geothermal exploration, as models representing a highly complex world approach reality.

    Background Enteric protozoa are associated with diarrhoeal illnesses in humans; however there are no recent studies on their epidemiology and geographical distribution in Australia. This study describes the epidemiology of enteric protozoa in the state of New South Wales and incorporates spatial analysis to describe their distribution. Design and methods Laboratory and clinical records from four public hospitals in Sydney for 910 patients, who tested positive for enteric protozoa over the period January 2007 - December 2010, were identified, examined and analysed. We selected 580 cases which had residence post code data available, enabling us to examine the geographic distribution of patients, and reviewed the clinical data of 252 patients to examine possible links between protozoa, demographic and clinical features. Results Frequently detected protozoa were Blastocystis spp. (57%), Giardia intestinalis (27%) and Dientamoeba fragilis (12%). The age distribution showed that the prevalence of protozoa decreased with age up to 24 years but increasing with age from 25 years onwards. The geographic provenance of the patients indicates that the majority of cases of Blastocystis (53.1%) are clustered in and around the Sydney City Business District, while pockets of giardiasis were identified in regional/rural areas. The distribution of cases suggests higher risk of protozoan infection may exist for some communities. Conclusions These findings provide useful information for policy makers to design and tailor interventions to target high risk communities. Follow-up investigation into the risk factors for giardiasis in regional/rural areas is needed. Significance for public health This research is significant since it provides the most recent epidemiological update on the common enteric protozoa affecting Australians. It reveals that enteric protozoa cause considerable disease burden in high risk city dwellers, and provides the evidence base for development of targeted interventions for their prevention and control in high risk populations. The prevalence of enteric protozoa in this metropolitan setting underscores that microorganisms do not respect borders and that a collaborative approach is needed to contain the global spread of infectious diseases. Incorporating spatial analysis is valuable in providing a compelling picture of the geographical distribution of these often neglected diseases. Local and State Public Health departments can use this information to support further inves- PMID:25343139

    This study investigates the mortality effect of primary and secondary PM2.5 related to ship exhaust in the Sydney greater metropolitan region of Australia. A detailed inventory of ship exhaust emissions was used to model a) the 2010/11 concentration of ship-related PM2.5 across the region, and b) the reduction in PM2.5 concentration that would occur if ships used distillate fuel with a 0.1% sulfur content at berth or within 300km of Sydney. The annual loss of life attributable to 2010/11 levels of ship-related PM2.5 and the improvement in survival associated with use of low-sulfur fuel were estimated from the modelled concentrations. In 2010/11, approximately 1.9% of the region-wide annual average population weighted-mean concentration of all natural and human-made PM2.5 was attributable to ship exhaust, and up to 9.4% at suburbs close to ports. An estimated 220years of life were lost by people who died in 2010/11 as a result of ship exhaust-related exposure (95% CI?: 140-290, where CI? is the uncertainty in the concentration-response coefficient only). Use of 0.1% sulfur fuel at berth would reduce the population weighted-mean concentration of PM2.5 related to ship exhaust by 25% and result in a gain of 390life-years over a twenty year period (95% CI?: 260-520). Use of 0.1% sulfur fuel within 300km of Sydney would reduce the concentration by 56% and result in a gain of 920life-years over twenty years (95% CI?: 600-1200). Ship exhaust is an important source of human exposure to PM2.5 in the Sydney greater metropolitan region. This assessment supports intervention to reduce ship emissions in the GMR. Local strategies to limit the sulfur content of fuel would reduce exposure and will become increasingly beneficial as the shipping industry expands. A requirement for use of 0.1% sulfur fuel by ships within 300km of Sydney would provide more than twice the mortality benefit of a requirement for ships to use 0.1% sulfur fuel at berth.

  13. Paleothermometry of the Sydney Basin

    Evidence from overprinting of magnetizations of Late Permian and Mesozoic rocks and from the rank of Permian coals and Mesozoic phytoclasts (coal particles) suggests that surface rocks in the Sydney Basin, eastern Australia, have been raised to temperatures of the order of 200 /sup 0/C or higher. As vitrinite reflectance, an index of coal rank or coalification, is postulated to vary predictably with temperature and time, estimates of the paleotemperatures in the Sydney Basin based on observed vitrinite reflectance measurements can be made in conjunction with reasonable assumptions about the tectonic and thermal histories of the basin. These estimates give maximum paleotemperatures of present day surface rocks in the range 60--249 /sup 0/C, depending on factors such as location in the basin, the thickness of the sediment eroded, and the maximum paleogeothermal gradient. Higher coal rank and, consequently, larger eroded thicknesses and paleogeothermal gradients occur along the eastern edge of the basin and may be related to seafloor spreading in the Tasman Sea on the basin's eastern margin. A theory of thermal activation of magnetization entailing the dependence of magnetic viscosity on the size distribution of the magnetic grains is used to obtain an independent estimate of the maximum paleotemperatures in the Sydney Basin. This estimate places the maximum paleotemperature in the range 250--300 /sup 0/C along the coastal region. Both coalification and thermal activation of magnetization models provide strong evidence of elevated paleotemperatures, which in places exceed 200 /sup 0/C, and the loss of sediment thicknesses in excess of 1 km due to erosion.

    At GR17 in Dublin in 2004, it was decided to hold GR18 in Sydney in 2007. Every six years, the GR conference (held every three years) and Amaldi meeting (held every two years) occur in the same year around July. This was to be the case in 2007. By mutual agreement of the International Society on General Relativity and Gravitation (ISGRG), which oversees the GR conferences and The Gravitational Wave International Committee (GWIC), which oversees the Amaldi meetings, it was decided to hold these two important conferences concurrently, for the first time, at the same venue, namely Sydney. At a time when the gravitational wave community was beginning to explore the possibility of searches to probe various aspects of the theory, the vision was to bring that community together with the community of gravitational theorists in order to better appreciate the work being done by both parties and to explore possibilities for future research using the mutual expertise. The logistics of running two such large meetings concurrently were considerable. The format agreed upon by the ISGRG and GWIC was the following: common plenary sessions in the mornings from Monday to Friday; six parallel GR workshop sessions and an Amaldi session each afternoon from Monday to Friday (except Wednesday); a combined poster session on Wednesday; a full day of Amaldi sessions on the final day (Saturday). The scientific programme for GR18 was overseen by a Scientific Organising Committee established by the ISGRG and chaired by Professor Sathyaprakash. The scientific programme for Amaldi7 was overseen by GWIC chaired by Professor Cerdonio. One of the highlights of the conferences was the breadth and quality of the plenary programme put together by the scientific committees. Not only did these talks give an excellent snapshot of the entire field at this time, but they also explored the interfaces with other related fields, which proved of special interest to participants. We were given superb overviews of the state of the art of: observational handles on dark energy; collider physics experiments designed to probe cosmology; gravitational dynamics of large stellar systems; and the use of analogue condensed-matter systems in the laboratory to investigate black hole event horizons. In the more mainstream areas we were given timely reviews of: the Gravity Probe B and STEP missions; quasi-local black hole horizons and their applications; cosmic censorship; the spin foam model approach to quantum gravity; the causal dynamical triangulations approach to quantum gravity; superstring theory applied to questions in particle physics; the current status and prospects for gravitational wave astronomy; ground-based gravitational wave detection; and technology developments for the future LISA mission. A special issue of Classical and Quantum Gravity (Volume 25, Number 11, 7 June 2008) is published as the proceedings of GR18 and Amaldi7. It contains the overview articles by the plenary speakers, the summaries of each GR18 workshop parallel session as provided by the workshop chairs, and the highlights of the Amaldi7 meeting as selected by the Amaldi7 chairs. Other Amaldi7 talks and posters appear in this refereed issue of the electronic Journal of Physics: Conference Series. This issue of JPCS and the CQG Special Issue are electronically linked.

    Mental health can be influenced by a number of neighbourhood physical and social environmental characteristics. We aimed to determine whether urban sprawl (based on population density) in Sydney, Australia, is associated with self-rated health and psychological distress. We used a cross-sectional multilevel study design. Individual level data on self-rated health and psychological distress were obtained from the 2006 and 2007 NSW Population Health Survey. We did not find significant associations between urban sprawl and self-rated health and psychological distress after controlling for individual and area level covariates. However, positive neighbourhood factors were generally associated with better self-rated health and lower psychological distress but few of these associations were statistically significant.

    On 5 August 1968, publication of the Harvard Committee's report on the subject of “irreversible coma” established a standard for diagnosing death on neurological grounds. On the same day, the 22nd World Medical Assembly met in Sydney, Australia, and announced the Declaration of Sydney, a pronouncement on death, which is less often quoted because it was overshadowed by the impact of the Harvard Report. To put those events into present-day perspective, the authors reviewed all papers published on this subject and the World Medical Association web page and documents, and corresponded with Dr A G Romualdez, the son of Dr A Z Romualdez. There was vast neurological expertise among some of the Harvard Committee members, leading to a comprehensible and practical clinical description of the brain death syndrome and the way to diagnose it. This landmark account had a global medical and social impact on the issue of human death, which simultaneously lessened reception of the Declaration of Sydney. Nonetheless, the Declaration of Sydney faced the main conceptual and philosophical issues on human death in a bold and forthright manner. This statement differentiated the meaning of death at the cellular and tissue levels from the death of the person. This was a pioneering view on the discussion of human death, published as early as in 1968, that should be recognised by current and future generations. PMID:18055899

    Soil and sediment samples from the Sydney basin were measured to ascertain fallout radionuclide activity concentrations and atom ratios. Caesium-137 ((137)Cs) was measured using gamma spectroscopy, and plutonium isotopes ((239)Pu and (240)Pu) were quantified using accelerator mass spectrometry (AMS). Fallout radionuclide activity concentrations were variable ranging from 0.6 to 26.1 Bq/kg for (137)Cs and 0.02-0.52 Bq/kg for (239+240)Pu. Radionuclides in creek sediment samples were an order of magnitude lower than in soils. (137)Cs and (239+240)Pu activity concentration in soils were well correlated (r(2) = 0.80) although some deviation was observed in samples collected at higher elevations. Soil ratios of (137)Cs/(239+240)Pu (decay corrected to 1/1/2014) ranged from 11.5 to 52.1 (average = 37.0 ± 12.4) and showed more variability than previous studies. (240)Pu/(239)Pu atom ratios ranged from 0.117 to 0.165 with an average of 0.146 (±0.013) and an error weighted mean of 0.138 (±0.001). These ratios are lower than a previously reported ratio for Sydney, and lower than the global average. However, these ratios are similar to those reported for other sites within Australia that are located away from former weapons testing sites and indicate that atom ratio measurements from other parts of the world are unlikely to be applicable to the Australian context.

    The interpretation of vehicle paint traces in forensic casework hinges on a number of factors including the type of paint, colour, number of layers, and background information. Vehicle colour surveys are an important source of information for the forensic paint examiner when interpreting the level of significance of a paint transfer between vehicles involved in a collision, or smears of vehicle paint left at a scene. The two surveys that are presented here investigated (i) the frequency of the colour of vehicles observed on both a motorway and suburban roads in Western Sydney and (ii) the frequency of different vehicle paint colours transferred to car park pillars and walls from five different car parks within North West Sydney, Australia. In the first survey, the highest frequency of vehicle colours recorded was white, grey, black and blue. The second survey resulted in very similar findings with the four most commonly seen colours across the five car parks being blue, white, red, and silver. The results in the second survey take into account the potential for anomalies within the data due to the use of painted service vehicles used within the car parks, such as trolleys and trailers. The results from both surveys were very similar to previous vehicle colour surveys that have been conducted and also corresponded to the vehicle colour registration data obtained from the NSW Roads and Maritime Service website. The results from these two surveys provide up to date statistics that can assist the forensic paint examiner with valuable background data when assessing the significance of vehicle paint evidence in casework.

    In order to quantify the risks from fire at the Wildland Urban Interface (WUI), it is important to understand where fires occur and their likelihood of spreading to the WUI. For each of 999 fires in the Sydney region we calculated the distance between the ignition and the WUI, the fire weather and wind direction and whether it spread to the WUI. The likelihood of burning the WUI was analysed using binomial regression. Weather and distance interacted such that under mild weather conditions, the model predicted only a 5% chance that a fire starting more than 2.5 km from the interface would reach it, whereas when the conditions are extreme the predicted chance remained above 30% even at distances further than 10 km. Fires were more likely to spread to the WUI if the wind was from the west and in the western side of the region. We examined whether the management responses to wildfires are commensurate with risk by comparing the distribution of distance to the WUI of wildfires with roads and prescribed fires. Prescribed fires and roads were concentrated nearer to the WUI than wildfires as a whole, but further away than wildfires that burnt the WUI under extreme weather conditions (high risk fires). 79% of these high risk fires started within 2 km of the WUI, so there is some argument for concentrating more management effort near the WUI. By substituting climate change scenario weather into the statistical model, we predicted a small increase in the risk of fires spreading to the WUI, but the increase will be greater under extreme weather. This approach has a variety of uses, including mapping fire risk and improving the ability to match fire management responses to the threat from each fire. They also provide a baseline from which a cost-benefit analysis of complementary fire management strategies can be conducted.

    Background Rates of use of amphetamine type stimulants among gay men have raised questions about the role of these drugs in increases in HIV infections and risk behaviour, but the role risk behaviours play with regard to illicit drug use within this population has not been investigated. Method Health in Men (HIM) is a cohort of 1427 HIV-negative men in Sydney, Australia. All participants undergo annual face-to-face interviews. We examined onset of use of methamphetamine and of ecstasy (MDMA) after their baseline interview. Results Among baseline non-frequent users who completed an annual follow-up interview, 67 commenced at least weekly use of ecstasy, while 71 commenced at least weekly use of methamphetamine. Factors independently associated with commencing more frequent use of these drugs included being younger, greater involvement in gay social life, and having engaged in unprotected anal intercourse with casual partners. Conclusons The transition from non- or less frequent drug use to more frequent drug use may be associated with changes in sexual behaviour. While it may be true that illicit drug use leads to unsafe sexual behaviour, it is equally true that illicit drugs are used to enhance sexual performance and pleasure. The relationship is bidirectional and complex and must be understood within the contexts of particular sexual sub-cultural practices: Engaging in sexual risk behaviour may be an indicator of future drug use as much as the reverse.

    The current investigation of marine water from 30 sites adjacent to stormwater outlets across the entire Sydney estuary is the first such research in Australia. The number of analytes detected were: 8/59 pharmaceutical compounds (codeine, paracetamol, tramadol, venlafaxine, propranolol, fluoxetine, iopromide and carbamazepine), 7/38 of the pesticides (2,4-dichlorophenoxyacetic acid (2,4-D), 3,4-dichloroaniline, carbaryl, diuron, 2-methyl-4-chlorophenoxyacetic acid (MCPA), mecoprop and simazine) and 0/3 of the personal care products (PCPs) analysed. An artificial sweetener (acesulfame) was detected, however none of the nine antibiotics analysed were identified. Sewage water is not discharged to this estuary, except infrequently as overflow during high-precipitation events. The presence of acesulfame (a recognised marker of domestic wastewater) and pharmaceuticals in water from all parts of the estuary after a dry period, suggests sewage water is leaking into the stormwater system in this catchment. The pesticides are applied to the environment and were discharged via stormwater to the estuary. PMID:26130525

  7. Evaluating the transport, health and economic impacts of new urban cycling infrastructure in Sydney, Australia – protocol paper

    2013-01-01

    Background There are repeated calls to build better cycling paths in Australian cities if the proportion of people cycling is to increase. Yet the full range of transport, health, environmental and economic impacts of new cycling infrastructure and the extent to which observed changes are sustained is not well understood. The City of Sydney is currently building a new bicycle network, which includes a new bicycle path separated from road traffic in the south Sydney area. This protocol paper describes a comprehensive method to evaluate this new cycling infrastructure. Method A cohort of residents within two kilometres of the new bicycle path will be surveyed at baseline before a new section of bicycle path is built, and again 12 and 24 months later to assess changes in travel behaviour, sense of community, quality of life and health behaviours. Residents in a comparable area of Sydney that will not get a new separated bike path will act as a comparison group. At baseline a sub-set of residents who volunteer will also take a small GPS device with them for one week to assess travel behaviour. Discussion This research should contribute to the advancement in evaluation and appraisal methods for cycling projects. PMID:24131667

    2009-10-01

    Sediment mantling the floor of Sydney estuary contains a wide range of chemicals at highly elevated concentrations over extensive areas. Appropriate sediment management decisions are urgently required to prevent further degradation of sediment quality and to minimize resulting adverse ecological effects. The objective of the present work was to provide a systematic, estuary-wide assessment of sediment risk and ecological/conservation value throughout the harbor to guide sediment management decisions. Sediment risk is the likelihood of sediment chemistry causing adverse biological effects to bottom-dwelling animals and was conducted using national sediment quality guidelines (SQGs) for single contaminants and the mean SQG quotient approach to assess chemical mixtures. Sediment risk was negligible at the mouth of the estuary, but increased strongly landwards. The ecological/conservation value assessment was conducted to identify sites that warrant different levels of protection and was conducted using the value of ecological communities and priority waterway use. Consideration of these two parameters combined enabled the estuary to be prioritized for management attention. The prioritization and identification of appropriate management strategies were determined through the use of management matrices also based on sediment risk and ecological/conservation value. A computer package is being developed to provide managers with information on sediment risk, ecological/conservation value, the urgency and the type of management intervention required for any location in Sydney estuary, in real-time. This approach to estuarine management is unique and will greatly improve effective management of Sydney estuary, and other harbors in urgent need of management action and protection.

    In 2009-2010 Sydney Water, the primary water utility in Sydney, conducted a comprehensive Smart Metering trial in residential homes in the suburb of Westleigh, in Sydney's north. The trial involved 1923 participants residing in 630 households. A whole-of-community method of engagement was applied to capture the views of residents from 12 to 70+ years of age. The trial examined the effects of the technology on the water consumption of an intervention group compared with that of a matched control group. After removing properties that had been sold since the beginning of the trial, properties in the study group were matched with a control group property on the basis of the household size, property size and the presence (or otherwise) of a swimming pool. The effects of the technology on consumption were measured and analyzed for the period July 2009 to June 2010, coupled with qualitative information that was collected throughout the duration of the study. A key finding was that households with the in-home display (IHD) installed, reduced their consumption by an average of over 6.8% over the study period when compared to the control group. Since completion of the study the community has not had any further interventions. The trial created an opportunity to examine the longer-term effects of the technology (June 2008 to September 2013). Consumption data collected over the 3 year posttrial period revealed that the participant group consumed 6.4% per month less water when compared to the pretrial period, whilst the matched control group consumed 1.3% per month more water when compared to the pretrial period. The reduced consumption of the participant group was maintained over time, demonstrating the long-term value of this technology.

    Approximately 85% of Australia's population live along the coastal fringe, an area with high exposure to extreme inundations such as tsunamis. However, to date, no Probabilistic Tsunami Hazard Assessments (PTHA) that include inundation have been published for Australia. This limits the development of appropriate risk reduction measures by decision and policy makers. We describe our PTHA undertaken for the Sydney metropolitan area. Using the NOAA NCTR model MOST (Method for Splitting Tsunamis), we simulate 36 earthquake-generated tsunamis with annual probabilities of 1:100, 1:1,000 and 1:10,000, occurring under present and future predicted sea level conditions. For each tsunami scenario we generate a high-resolution inundation map of the maximum water level and flow velocity, and we calculate the exposure of buildings and critical infrastructure. Results indicate that exposure to earthquake-generated tsunamis is relatively low for present events, but increases significantly with higher sea level conditions. The probabilistic approach allowed us to undertake a comparison with an existing storm surge hazard assessment. Interestingly, the exposure to all the simulated tsunamis is significantly lower than that for the 1:100 storm surge scenarios, under the same initial sea level conditions. The results have significant implications for multi-risk and emergency management in Sydney. PMID:25492514

    Objectives To determine the body mass, cardiovascular and metabolic characteristics of young people presenting for mental healthcare. Design Cross-sectional assessments of body mass, cardiovascular and metabolic risk factors. Setting Two primary-care based sites in Sydney, Australia for young people in the early stages of mental disorders. Participants A clinical sample of young people (12–30?years) with mental health problems. Outcome measures Daily smoking rates, body mass index (BMI), blood glucose and lipids, blood pressure (BP) and pulse rate. Results Of 1005 young people who had their BMI determined (62% female; 19.0±3.5?years), three quarters (739/1005) also had BP recordings and one-third (298/1005) had blood sampling. Clinically, 775 were assigned to one of three diagnostic categories (anxious-depression: n=541; mania-fatigue, n=104; developmental-psychotic n=130). The profile of BMI categories approximated that of the comparable segments of the Australian population. Older age, lower levels of social functioning and higher systolic BP were all associated with high BMI. In a subset (n=129), current use of any psychotropic medication was associated (p<0.05) with increased BMI. Almost one-third of cases were current daily smokers (compared to population rate of 11%). Males had a higher proportion of raised glucose and high-density lipoprotein (HDL) compared to females (9.3% and 34.1% vs 2.1% and 5.9%, respectively). Overall, there was no relationship between BMI and fasting glucose but significant relationships with triglycerides and HDL were noted. Furthermore, there were no significant relationships between diagnostic subgroup and metabolic profiles. Conclusions Daily smoking rates are increased among young people presenting for mental healthcare. However, these young people do not demonstrate adverse cardiometabolic profiles. The high levels of smoking, and association of BMI with adverse social circumstances, suggest that risk factors for chronic disease are already present and likely to be compounded by medication and social disadvantage.

    The response of vegetation after a wildfire is dependent on factors such as fire intensity and vegetation type. Australian woody vegetation species have evolved two mechanisms of disturbance survival i) seed germination (obligate seeders) and ii) resprouting from dormant vegetative buds and/or lignotubers (obligate resprouters). The majority of post wildfire vegetation response studies conducted in Victoria, Australia have been in obligate seeder dominant communities. These studies have found that there is a significant delay in species germination as they rely on the seed bank. Those studies do not represent the response of vegetation in the Sydney Basin, which is dominated by obligate resprouter species. This study examines the vegetation recovery of four burnt subcatchments affected by the summer 2001/02 wildfire event and compared to three unburnt subcatchments. The study uses a 20 year time series of Landsat and SPOT satellite data assessing vegetation 10 years pre-wildfire and 10 years post-wildfire on an annual basis. Several vegetation indices were compared to assess the health and integrity of eucalypt forests and woodlands (NDVI, NDVIc, NBR). This study provides land managers with crucial information about the response of vegetation communities to wildfire within the Sydney Basin.

  18. Field Evaluation of Melolure, a Formate Analogue of Cuelure, and Reassessment of Fruit Fly Species Trapped in Sydney, New South Wales, Australia.

    In Australia, tephritids are usually attracted to either cuelure or methyl eugenol. Methyl eugenol is a very effective lure, but cuelure is less effective likely due to low volatility. A new formate analogue of cuelure, melolure, has increased volatility, resulting in improved efficacy with the melon fruit fly, Bactrocera cucurbitae Coquillett. We tested the efficacy of melolure with fruit fly species in Sydney as part of the National Exotic Fruit Fly Monitoring programme. This monitoring programme has 71 trap sites across Sydney, with each trap site comprising separate Lynfield traps containing either cuelure, methyl eugenol, or capilure lure. In 2008, an additional Lynfield trap with melolure plugs was added to seven sites. In 2009 and 2010, an additional Lynfield trap with melolure wicks was added to 11 trap sites and traps were monitored fortnightly for 2?yr. Capture rates for melolure traps were similar to cuelure traps for Dacus absonifacies (May) and Dacus aequalis (Coquillet), but melolure traps consistently caught fewer Bactrocera tryoni (Froggatt) than cuelure traps. However, trap sites with both a cuelure and melolure traps had increased capture rates for D. absonifacies and D. aequalis, and a marginally significant increase for B. tryoni. Melolure plugs were less effective than melolure wicks, but this effect may be related to lure concentration. The broader Bactrocera group species were attracted more to cuelure than melolure while the Dacus group species were attracted more to melolure than cuelure. There is no benefit in switching from cuelure to melolure to monitor B. tryoni, the most important fruit fly pest in Australia. PMID:26470243

    The purpose is to explore the multilevel spatial distribution of depressive symptoms among migrant mothers in South Western Sydney and to identify any group level associations that could inform subsequent theory building and local public health interventions. Migrant mothers (n=7256) delivering in 2002 and 2003 were assessed at 2-3 weeks after delivery for risk factors for depressive symptoms. The binary outcome variables were Edinburgh Postnatal Depression Scale scores (EPDS) of >9 and >12. Individual level variables included were: financial income, self-reported maternal health, social support network, emotional support, practical support, baby trouble sleeping, baby demanding and baby not content. The group level variable reported here is aggregated social support networks. We used Bayesian hierarchical multilevel spatial modelling with conditional autoregression. Migrant mothers were at higher risk of having depressive symptoms if they lived in a community with predominantly Australian-born mothers and strong social capital as measured by aggregated social networks. These findings suggest that migrant mothers are socially isolated and current home visiting services should be strengthened for migrant mothers living in communities where they may have poor social networks.

    A petrographic, isotopic and fluid inclusion investigation of Permo-Triassic sandstones in the Sydney Basin has enabled reconstruction of the history of fluid flow. Diagenetic cements in Triassic sandstones comprise, in order, grain coating clays and carbonates, pore filling carbonates, kaolin, quartz, late interstitial carbonate and illite. Diagenesis in the Permian sandstones began with pore filling siderite prior to saddle ankerite, followed by quartz and then illite and late carbonates. Fluid rock interaction during burial resulted in increases in pore water 8180 from depositional values of -17[per thousand] to about -12[per thousand] to -7[per thousand] at the time of quartz overgrowth crystallization and to between -7[per thousand] to -1[per thousand] at the time of illite crystallisation. Interpretation of fluid inclusion data and maturity measurements indicates that heat flow increased during the Triassic and Jurassic, reaching a maximum of about 2.1 HFU in the Cretaceous. Late Cretaceous uplift, cooling and erosion was initiated at the same time as, and probably related to, the initiation of Tasman Sea rifting. The rocks had previously been more deeply buried by 1500-2100m. The uplift resulted in cessation of illite diagenesis timed at 90Ma and meteoric water invasion of the sandstones in turn causing partial resetting of [delta]D compositions of the diagenetic clays to less D-depleted values.

    Background Viewed through the micro focus of an interpretive lens, medical anthropology remains mystified because interpretivist explanations seriously downplay the given context in which individual health seeking-behaviours occur. This paper draws upon both the interpretivist and political economy perspectives to reflect on the ethno medical practices within the Korean-Australian community in Sydney. Methods We draw on research data collected between 1995 and 1997 for an earlier study of the use of biomedical and traditional medicine by Korean-Australians in Sydney. A total of 120 interviews were conducted with a range of participants, including biomedical doctors, traditional health professionals, Korean community leaders and Korean migrants representing a range of socio-economic backgrounds and migration patterns. Results and Discussion First, the paper highlights the extent to which the social location of migrants in a host society alters or restructures their initial cultural practices they bring with them. Second, taking hanbang medicine in the Korean-Australian community as an illustrative case, the paper explores the transformation of the dominant biomedicine in Australia as a result of the influx of ethnomedicine in the era of global capitalism and global movement. Conclusion In seeking to explain the popularity and supply of alternative health care, it is important to go beyond the culture of each kind of health care itself and to take into consideration the changes occurring at societal, national and global levels as well as consequential individual response to the changes. New social conditions influence the choice of health care methods, including herbal/alternative medicine, health foods and what are often called New Age therapies. PMID:17201916

    Australia is vulnerable to the impacts of tsunamis and exposure along the SE coast of New South Wales is especially high. Significantly, this is the same area reported to have been affected by repeated large magnitude tsunamis during the Holocene. Efforts are under way to complete probabilistic risk assessments for the region but local government planners and emergency risk managers need information now about building vulnerability in order to develop appropriate risk management strategies. We use the newly revised PTVA-3 Model (Dall'Osso et al., 2009a, b) to assess the relative vulnerability of buildings to damage from a "worst case tsunami" defined by our latest understanding of regional risk - something never before undertaken in Australia. We present selected results from an investigation of building vulnerability within the local government area of Manly - an iconic coastal area of Sydney. We show that a significant proportion of buildings (in particular, residential structures) are classified as having "High" and "Very High" Relative Vulnerability Index scores. Furthermore, other important buildings (e.g., schools, nursing homes and transport structures) are also vulnerable to damage. Our results have serious implications for immediate emergency risk management, longer-term land-use zoning and development, and building design and construction standards. Based on the work undertaken here, we recommend further detailed assessment of the vulnerability of coastal buildings in at risk areas, development of appropriate risk management strategies and a detailed program of community engagement to increase overall resilience. Last, we propose the wider application of the PTVA-3 Model as a tool for building vulnerability assessment. Dall'Osso, D., Gonella, M., Gabbianelli, G., Withycombe, G. and Dominey-Howes, D. (2009a).

    Laboratory survival tests were conducted with an indigenous infaunal amphipod, Corophium colo, on 103 sediment samples from Sydney Harbor (NSW, Australia) and vicinity, containing a wide range of chemicals and concentrations. The present study describes the sensitivity of C. colo to the sediments and compares the results to data for North American amphipods (Rhepoxynius abronius and Ampelisca abdita) previously used to establish and validate sediment-quality guidelines (SQGs). The incidence of toxicity increased with increasing contamination, as indicated by increasing numbers of SQGs exceeded and increasing mean SQG quotients. The incidence of highly toxic results (p < 0.05 and mean amphipod survival of < 80% that of controls) for highly contaminated samples was approximately half (28-40%) that of a large U.S. database (74%). The incidence of highly toxic responses for samples with intermediate levels of contamination also was lower in the present study (5-13%) compared to the results in large U.S. studies (approximately 30-50%). Corophium colo reburial tests showed greater sensitivity compared to survival tests, with a maximum incidence of statistically significant responses in moderately contaminated sediments of 70%. The present study showed that adult Corophium organisms are suitable for testing lethal responses in highly contaminated sediments (i.e., with mean effects range-median quotients of >1.5). Reburial results provide additional sensitivity. PMID:16268156

    Background This paper describes the experiences of Australian general practitioners (GPs) in managing problematic crystal methamphetamine (crystal meth) use among two groups of male patients: gay men and HIV positive men. Methods Semi-structured qualitative interviews with GPs with HIV medication prescribing rights were conducted in Sydney, Adelaide and a rural-coastal town in New South Wales between August and October 2006. Participants were recruited from practices with high caseloads of gay and HIV positive men. Results Sixteen GPs were recruited from seven practices to take part in interviews. Participants included 14 male GPs and two female GPs, and the number of years each had been working in HIV medicine ranged from two to 24. Eleven of the GPs who were based in Sydney raised the issue of problematic crystal meth use in these two patient populations. Five key themes were identified: an increasing problem; associations with depression; treatment challenges; health services and health care; workforce issues. Conclusion Despite study limitations, key implications can be identified. Health practitioners may benefit from broadening their understandings of how to anticipate and respond to problematic levels of crystal meth use in their patients. Early intervention can mitigate the impact of crystal meth use on co-morbid mental illness and other health issues. Management of the complex relationships between drug use, depression, sexuality and HIV can be addressed following a 'stepped care' approach. General practice guidelines for the management of crystal meth use problems should address specific issues associated with gay men and HIV positive men. GPs and other health practitioners must appreciate drug use as a social practice in order to build trust with gay men to encourage full disclosure of drug use. Education programs should train health practitioners in these issues, and increased resourcing provided to support the often difficult task of caring for people who use crystal meth. Greater resourcing of acute care and referral services can shift the burden away from primary care and community services. Further investigation should consider whether these findings are reproducible in other general practice settings, the relationship between depression, drug use and HIV medication, and challenges facing the HIV general practice workforce in Australia.

    2014-01-01

    Background The aim of the qualitative study reported here was to: 1) explain the observed clustering of postnatal depressive symptoms in South Western Sydney; and 2) identify group-level mechanisms that would add to our understanding of the social determinants of maternal depression. Methods Critical realism provided the methodological underpinning for the study. The setting was four local government areas in South Western Sydney, Australia. Child and Family practitioners and mothers in naturally occurring mothers groups were interviewed. Results Using an open coding approach to maximise emergence of patterns and relationships we have identified seven theoretical concepts that might explain the observed spatial clustering of maternal depression. The theoretical concepts identified were: Community-level social networks; Social Capital and Social Cohesion; "Depressed community"; Access to services at the group level; Ethnic segregation and diversity; Supportive social policy; and Big business. Conclusions We postulate that these regional structural, economic, social and cultural mechanisms partially explain the pattern of maternal depression observed in families and communities within South Western Sydney. We further observe that powerful global economic and political forces are having an impact on the local situation. The challenge for policy and practice is to support mothers and their families within this adverse regional and global-economic context. PMID:24460690

    Using a physiologically relevant thermal comfort index (OUT_SET*), an analysis of the week-by-week human thermal climate of Sydney was carried out for three levels of metabolic activity. The OUT_SET* index is an outdoor version of the widely used indoor comfort index called the standard effective temperature (SET*) incorporating air and mean radiant temperatures, relative humidity, air velocity, clothing insulation and activity level. The outdoor comfort zone for Sydney in terms of OUT_SET* was found from earlier subjective field studies to be in the range 23.8-28.5°C. The analysis indicated that the mid-summer period (weeks 43 through to 12 in the Southern Hemisphere) was most suitable for sedentary outdoor activities (e.g. watching spectator sport), whereas the mid-winter period was more suitable for light activities such as walking. Sydney's winter was found to be a very suitable season for tourism in many respects because of (a) low rainfall months, like August, and (b) the ability to undertake light activities while remaining within the outdoor comfort zone. For high metabolic activities during the day, for example the mass participation Sydney City-to-Surf fun run, it was found that the threshold limit value for increased risk of heat stress (as defined by ISO 7243, 1989) is exceeded up to 50% of the time during the summer (weeks 50 through to 9 at 3 p.m.) at the 90th percentile probability level. The methods and results of this study should be relevant to end-users such as architects, engineers, outdoor-event planners and the tourism industry in general.

    Sixteen polycyclic aromatic hydrocarbons (PAHs) considered as priority environmental pollutants were analysed in surface natural soils (NS), road-deposited sediments (RDS), and water sediments (WS) at Kogarah in Sydney, Australia. Comparisons were made of their concentration distributions, likely sources and potential toxicities. The concentrations (mg/kg) in NS, RDS, and WS ranged from 0.40 to 7.49 (mean 2.80), 1.65 to 4.00 (mean 2.91), and 0.49 to 5.19 (mean 1.76), respectively. PAHs were dominated by relatively high molecular weight compounds with more than three fused benzene rings, indicating that high temperature combustion processes were their predominant sources. The proportions of high molecular weight PAHs with five or six fused benzene rings were higher in NS than in RDS, whereas the low molecular weight PAHs were higher in RDS. Concentrations of all PAHs compounds were observed to be the lowest in WS. The concentrations of most of the high molecular weight PAHs significantly correlated with each other in RDS and WS. All PAHs (except naphthalene) were significantly correlated in NS suggesting a common PAH source. Ratios for individual diagnostic PAHs demonstrated that the primary source of PAHs in WS and NS was of pyrogenic origin (combustion of petroleum (vehicle exhaust), grass, and wood) while in RDS it was petrogenic (i.e. unburned or leaked fuel and oil, road asphalt, and tyre particles) as well as pyrogenic. The potential toxicities of PAHs calculated using a toxicity equivalent quotient (TEQ) were all low but higher for NS compared to WS and RDS. PMID:24732030

    This study addresses the recent climatology of hail occurrence in the Greater Metropolitan Severe Thunderstorm Warning Area (GMSTWA) of New South Wales, Australia, which is a sprawling suburban area, with a population of nearly 4.7 million and one of Australia's largest metropolis. The main objective is to highlight the recent temporal-spatial fluctuations of hailstone frequencies and magnitudes for each of recognized and vastly inhabited Local Government Areas (LGAs). The relevant hail event data from 1989 to 2013 were initially derived from the severe storm archive of Australian Bureau of Meteorology. A climatologically oriented GIS technique was applied in the examining and mapping procedure of all hail events and hail days reported throughout the study area. By applying a specific criterion, all severe hails (defined as 2 cm or more in diameter) were cautiously selected and then imported into the ArcGIS software for relevant analysis. Appropriate data layers were stored in a unique database to allow logical integration of the data directly into some geoprocessing functions, mainly for querying, analyzing and mapping purposes in a model-builder setting. The database includes 357 hailstones with sizes 2-11 cm and occurred in 169 hail days across the region during the past 25 years. The models have established that hailstones are neither temporally nor spatially uniform in magnitude throughout the study area. Temporal analysis indicated that most of hail events occurred predominately in the afternoons with peak time of 1-5 p.m. EST. They were particularly common in spring and summer, and reached maximum frequency in November and December. There was an average of 14.3 events each year, but a significant decreasing trend in terms of hail frequency and associated magnitude in the recent years has been identified. In turn, spatial models also established three main distribution patterns over the study area, which include the Sydney Metropolitan, coastal and pronounced topographic effects. Based on the understanding of the favorable factors for thunderstorm development in the GMSTWA, the potential impacts from climate variability and future climate change have been briefly discussed.

  15. Tackling the Issues of Landscape Characterisation for Natural Resource Management in Urban and Peri-urban Western Sydney, Australia: Application of the Hydro-Geologic Landscapes Approach

    Dryland salinity is a natural resource management issue and a planning hazard in urban/peri-urban Western Sydney, where there is enormous development pressure. The level of detail available on local geological, hydrogeologic and soils maps commonly does not provide sufficient detail for sub-catchment scale urban development planning and natural resource management (NRM) decision-making. The dominant lithologies for the area are relatively thick (up to 300m), flat-lying, Triassic fluvial and shallow marine siliciclastic sediments of the Sydney Basin. Localised areas of Cainozoic gravels cover the palaeo-landscapes developed on older rocks, and modern fluvial processes along the Hawkesbury River and tributaries continue to modify the landscape. Salt is concentrated in this landscape through aeolian accession and deposition from oceanic aerosols, but almost never as fossil (connate) salts. The redistribution of salts by the process of aeolian accession typically takes place when the salts are coupled with windblown dust known as parna. For south-eastern NSW, this dust originates from areas which are more arid, such as the western regions of the NSW and Victorian states. Aerosols from the ocean can be responsible for the deposition of salts up to a few hundred kilometres from their source. This process is responsible for a significant contribution of salt in the Sydney area. Field observations have shown that salt outbreaks are more dominant on some Sydney Basin units, specifically the Wianamatta Group sediments, some Cainozoic units, and along many active drainage systems. The Wianamatta Group sediments comprise three sub-groups; the Bringelly Shale, Minchinbury Sandstone and Ashfield Shale. The Cainozoic sediments comprise at least three units; the Saint Mary's Formation, Rickaby's Creek Gravels and Londonderry Clay. In Western Sydney these successions form an east-west oriented, tear-drop-shaped sub-basin, the Cumberland Basin, that narrows and thins to the east. In the field, it has proven difficult to consistently discriminate between the Wianamatta Group sequence and the Cainozoic sediments without precise geomorphological characterisation of the landscape coupled with stratigraphic profiling. Further, terraces in the Recent fluvial deposits contribute to the development of a complex "stepped" landscape structure. Detailed biophysical typing of landscapes in this area using Hydro-Geologic Landscape characterisation, a scaled and modified Groundwater Flow System approach, allows constraint of salt storage and distribution, and development of conceptual models for saline fluid flow, and hence informs urban planning and NRM decision-making and provides evidence for implementation of preferred land use practices. Strategic planning for dryland salinity, with respect to urban development, must address two principal concerns: the manifestation of land salinisation, and salinisation of waterways in this landscape; and, the impact of a high runoff, high recharge, low perenniality, low groundwater-consumption land use model (e.g. high density suburban housing). Land salinisation impacts on engineering structures, roads, and built infrastructure, and stresses vegetation. Water quality is an issue, especially if development occurs in a drinking water catchment. In order to minimise these impacts on future urban developments, a well-structured decision support system that underpins planning is required. Biophysical characterisation of the landscapes, using the Hydro-Geologic Landscapes (HGL) technique, is complimented by careful studies of the stratigraphy of the Wianamatta Group sediments, the overlying Cainozoic sediments and the Quaternary-Recent deposits in this area. In addition a preliminary groundwater study has been undertaken. Understanding of the detailed regolith geology, hydrology, geomorphology and geological structures allows for appropriate management in a delicate landscape and underpins development planning in outer urban Sydney.

    Background Circumcision status was examined as an independent risk factor for STIs in the HIM cohort of homosexual men in Sydney. Methods From 2001–2004, 1,427 initially HIV-negative men were enrolled and followed to mid-2007. All participants were offered annual STI testing. Past history of STIs was collected at baseline and information on sexual risk behaviors, every 6 months. At annual face-to-face visits, participants reported STI diagnoses made in the previous year. Results Circumcision was not associated with prevalent or incident HSV-1, HSV-2, or self-reported genital warts. There was also no independent association of circumcision with incident urethral gonorrhea or chlamydia. Being circumcised was associated with a significantly reduced risk of incident (HR 0.35, 95% CI 0.15–0.84), but not prevalent (OR 0.71, 95% CI 0.35–1.44) syphilis. The association was somewhat stronger among men who reported predominantly insertive unprotected anal intercourse (HR 0.10, 95% CI 0.01–0.82). Conclusions These are the first prospective data in homosexual men to assess circumcision status as a risk factor for STIs. Circumcised men were at reduced risk of incident syphilis but no other prevalent or incident STIs. Circumcision is unlikely to have a substantial public health impact in reducing acquisition of most STIs in homosexual men. PMID:19911990

    Australia is vulnerable to the impacts of tsunamis and exposure along the SE coast of New South Wales is especially high. Significantly, this is the same area reported to have been affected by repeated large magnitude tsunamis during the Holocene. Efforts are under way to complete probabilistic risk assessments for the region but local government planners and emergency risk managers need information now about building vulnerability in order to develop appropriate risk management strategies. We use the newly revised PTVA-3 Model (Dall'Osso et al., 2009) to assess the relative vulnerability of buildings to damage from a "worst case tsunami" defined by our latest understanding of regional risk - something never before undertaken in Australia. We present selected results from an investigation of building vulnerability within the local government area of Manly - an iconic coastal area of Sydney. We show that a significant proportion of buildings (in particular, residential structures) are classified as having "High" and "Very High" Relative Vulnerability Index scores. Furthermore, other important buildings (e.g., schools, nursing homes and transport structures) are also vulnerable to damage. Our results have serious implications for immediate emergency risk management, longer-term land-use zoning and development, and building design and construction standards. Based on the work undertaken here, we recommend further detailed assessment of the vulnerability of coastal buildings in at risk areas, development of appropriate risk management strategies and a detailed program of community engagement to increase overall resilience.

    The first World Weather Research Programme (WWRP) Forecast Demonstration Project (FDP), with a focus on nowcasting, was conducted in Sydney, Australia, from 4 September to 21 November 2000 during a period associated with the Sydney 2000 Olympic Games. Through international collaboration, nine nowcasting systems from the United States, United Kingdom, Canada, and Australia were deployed at the Sydney Office of the Bureau of Meteorology (BOM) to demonstrate the capability of modern forecast systems and to quantify the associated benefits in the delivery of a real-time nowcast service. On-going verification and impact studies supported by international committees assisted by the WWRP formed an integral part of this project. A description is given of the project, including component systems, the weather, and initial outcomes. Initial results show that the nowcasting systems tested were transferable and able to provide valuable information enhancing BOM nowcasts. The project provided for unprecedented interchange of concepts and ideas between forecasters, researchers, and end users in an operational framework where they all faced common issues relevant to real time nowcast decision making. A training workshop sponsored by the World Meteorological Organization (WMO) was also held in conjunction with the project so that other member nations could benefit from the FDP.

    How staff and students travel to university can impact their physical activity level. An online survey of physical activity and travel behaviour was conducted in early November 2012 to inform planning of physical activity and active travel promotion programs at the University of Sydney, Australia as part of the "Sit Less, Move More" sub-committee of the Healthy University Initiative, and as baseline data for evaluation. There were 3,737 useable responses, 60% of which were from students. Four out of five respondents travelled to the University on the day of interest (Tuesday, November 30, 2012). The most frequently used travel modes were train (32%), car as driver (22%), bus (17%), walking (17%) and cycling (6%). Staff were twice as likely to drive as students, and also slightly more likely to use active transport, defined as walking and cycling (26% versus 22%). Overall, 41% of respondents were sufficiently active (defined by meeting physical activity recommendations of 150 min per week). Participants were more likely to meet physical activity recommendations if they travelled actively to the University. With a high proportion of respondents using active travel modes or public transport already, increasing the physical activity levels and increasing the use of sustainable travel modes would mean a mode shift from public transport to walking and cycling for students is needed and a mode shift from driving to public transport or active travel for University staff. Strategies to achieve this are discussed. PMID:23939390

    PubMed

    Sipponen, Pentti; Price, Ashley B

    2011-01-01

    The roots of research into gastritis go back into the early decades of the 20th century. Modern aspects of its classification and knowledge of its biological course and consequences were relatively well known even at the time that Helicobcter pylori was discovered by Robin Warren and Barry Marshall in 1982. This discovery, however, significantly changed the field, establishing that the commonest form of gastritis is simply an infectious disease, a finding that raised enormous interest in the subject amongst gastroenterologists, microbiologists, pathologists and basic researchers. However, many of these "new" players in the field often had a limited knowledge of the morphological aspects of gastric inflammations and chronic gastritis. As a consequence in the late 1980's a Working Party was set up to review the biology and natural course of chronic gastritis, to propose a new classification for gastritis, and to provide simple guidelines for reporting the pathology of gastritis in endoscopic biopsies in an attempt to bring uniformity to the subject and facilitate comparative studies in what was to be an era of high research activity. These guidelines, The Sydney System: A New Classification of Gastritis was presented to the World Congress of Gastroenterology in Sydney in 1990, and was later published as six papers in the Journal of Gastroenterology and Hepatology. Now, twenty years on, this review looks back on the birth of Sydney System and why it is still important and successful. PMID:21199511

    Concentrations of PAHs, PCBs, metals and lipids in hepatopancreas of rock crabs (Cancer irroratus) were measured in Sydney Harbour (SH) for one year prior to remediation and three years of remediation of the Sydney Tar Ponds (STP), Nova Scotia. Low level concentrations of PCBs and metals were measured, although PAHs were mostly undetected. Metal concentrations showed little spatio-temporal variability, although highest concentrations of As, Cd and Cu were measured at reference stations furthest from the STP remediation site. Mercury concentrations were at least an order of magnitude lower than Canadian guidelines. Moderately elevated PCB concentrations were detected in crabs near Muggah Creek, but these were generally not higher than those measured during baseline. Despite remediation activities, current contaminant burdens measured in crabs were much lower than previously reported in other studies of crabs and lobster in industrial harbours in eastern Canada, due in part to natural recovery of SH sediments.

    2008-06-01

    At GRG17 in Dublin in 2004, it was decided to hold GRG18 in Sydney in 2007. Every six years, the GRG conference (held every three years) and Amaldi meeting (held every two years) occur in the same year around July. This was to be the case in 2007. By mutual agreement of the International Society on General Relativity and Gravitation (ISGRG), which oversees the GR conferences and The Gravitational Wave International Committee (GWIC), which oversees the Amaldi meetings, it was decided to hold these two important conferences concurrently, for the first time, at the same venue, namely Sydney. At a time when the gravitational wave community was beginning to explore the possibility of searches to probe various aspects of the theory, the vision was to bring that community together with the community of gravitational theorists in order to better appreciate the work being done by both parties and to explore possibilities for future research using the mutual expertise. The logistics of running two such large meetings concurrently were considerable. The format agreed upon by the ISGRG and GWIC was the following: common plenary sessions in the mornings from Monday to Friday; six parallel GR workshop sessions and an Amaldi session each afternoon from Monday to Friday (except Wednesday); a combined poster session on Wednesday; a full day of Amaldi sessions on the final day (Saturday). The scientific programme for GRG18 was overseen by a Scientific Organising Committee established by the ISGRG and chaired by Professor Sathyaprakash. The scientific programme for Amaldi7 was overseen by GWIC chaired by Professor Cerdonio. One of the highlights of the conferences was the breadth and quality of the plenary programme put together by the scientific committees. Not only did these talks give an excellent snapshot of the entire field at this time, but they also explored the interfaces with other related fields, which proved of special interest to participants. We were given superb overviews of the state of the art of: observational handles on dark energy; collider physics experiments designed to probe cosmology; gravitational dynamics of large stellar systems; and the use of analogue condensed-matter systems in the laboratory to investigate black hole event horizons. In the more mainstream areas we were given timely reviews of: the Gravity Probe B and STEP missions; quasi-local black hole horizons and their applications; cosmic censorship; the spin foam model approach to quantum gravity; the causal dynamical triangulations approach to quantum gravity; superstring theory applied to questions in particle physics; the current status and prospects for gravitational wave astronomy; ground-based gravitational wave detection; and technological developments for the future LISA mission. This issue is published as the proceedings of GRG18 and Amaldi7. It contains the overview articles by the plenary speakers, the summaries of each GRG18 workshop parallel session as provided by the workshop chairs, and the highlights of the Amaldi7 meeting as selected by the Amaldi7 chairs. Other Amaldi7 talks and posters will appear as articles in a refereed issue of the electronic Journal of Physics Conference Series.

    Phenoloxidase (PO) activity was studied in Sydney rock oysters (Saccostrea glomerata). As in other molluscs, PO was found to exist as a pro-enzyme (proPO) in hemocytes. ProPO could be activated to PO by exogenous proteases (trypsin and chymotrypsin), exposure of hemocytes to pathogen-associated molecular patterns (PAMPs) and by the detergents, Triton X-100 and sodium dodecyl sulphate (SDS). Inhibition studies confirmed the proPO activating system of Sydney rock oysters is a proteinase cascade in which Ca2+ dependent serine proteinases proteolytically convert proPO into active PO. Activated PO was found to be a tyrosinase-like enzyme that is responsible for both monophenolase and diphenolase activity. The bifunctional PO had higher affinity for the monophenol, hydroquinine monomethyl ether (4HA) (Km=4.45+/-1.46 mM) than for the diphenol, l-DOPA (Km=10.27+/-1.33 mM). Maximum enzyme activity was evident at 37 degrees C, pH 8 and at salinities of between 30 and 37 ppt. Melanogenesis catalysed by the active enzyme is a composite of eumelanin and the product of a sclerotin pathway combining DOPA decarboxylase with PO activity. PMID:17950018

    Angiostrongylus cantonensis and Angiostrongylus mackerrasae are metastrongyloid nematodes that infect various rat species. Terrestrial and aquatic molluscs are intermediate hosts of these worms while humans and dogs are accidental hosts. Angiostrongylus cantonensis is the major cause of angiostrongyliasis, a disease characterised by eosinophilic meningitis. Although both A. cantonensis and A. mackerrasae are found in Australia, A. cantonensis appears to account for most infections in humans and animals. Due to the occurrence of several severe clinical cases in Sydney and Brisbane, the need for epidemiological studies on angiostrongyliasis in this region has become apparent. In the present study, a conventional PCR and a TaqMan assay were compared for their ability to amplify Angiostrongylus DNA from DNA extracted from molluscs. The TaqMan assay was more sensitive, capable of detecting the DNA equivalent to one hundredth of a nematode larva. Therefore, the TaqMan assay was used to screen molluscs (n=500) of 14 species collected from the Sydney region. Angiostrongylus DNA was detected in 2 of the 14 mollusc species; Cornu aspersum [14/312 (4.5%)], and Bradybaenia similaris [1/10 (10%)], which are non-native terrestrial snails commonly found in urban habitats. The prevalence of Angiostrongylus spp. was 3.0% ± 0.8% (CI 95%). Additionally, experimentally infected Austropeplea lessoni snails shed A. cantonensis larvae in their mucus, implicating mucus as a source of infection. This is the first Australian study to survey molluscs using real-time PCR and confirms that the garden snail, C. aspersum, is a common intermediate host for Angiostrongylus spp. in Sydney.

    Angiostrongylus cantonensis and Angiostrongylus mackerrasae are metastrongyloid nematodes that infect various rat species. Terrestrial and aquatic molluscs are intermediate hosts of these worms while humans and dogs are accidental hosts. Angiostrongylus cantonensis is the major cause of angiostrongyliasis, a disease characterised by eosinophilic meningitis. Although both A. cantonensis and A. mackerrasae are found in Australia, A. cantonensis appears to account for most infections in humans and animals.

    Norovirus is the primary cause of acute gastroenteritis in individuals of all ages. In Australia, a new strain of norovirus (GII.4) was identified in March 2012, and this strain has spread rapidly around the world. In August 2012, this new GII.4 strain was identified in patients in South Korea. Therefore, to examine the characteristics of the epidemic norovirus GII.4 2012 variant in South Korea, we conducted KM272334 full-length genomic analysis. The genome of the gg-12-08-04 strain consisted of 7,558?bp and contained three open reading frame (ORF) composites throughout the whole genome: ORF1 (5,100?bp), ORF2 (1,623?bp), and ORF3 (807?bp). Phylogenetic analyses showed that gg-12-08-04 belonged to the GII.4 Sydney 2012 variant, sharing 98.92% nucleotide similarity with this variant strain. According to SimPlot analysis, the gg-12-08-04 strain was a recombinant strain with breakpoint at the ORF1/2 junction between Osaka 2007 and Apeldoorn 2008 strains. This study is the first report of the complete sequence of the GII.4 Sydney 2012 strain in South Korea. Therefore, this may represent the standard sequence of the norovirus GII.4 2012 variant in South Korea and could therefore be useful for the development of norovirus vaccines. PMID:25688356

    TTU measurements included semi-continuous monitoring of acid gases, gaseous ammonia and total soluble anionic constituents and ammonium in atmospheric particulate matter (with the 50 percent cut off in the collection/measurement system lying above 10 micron mass median aerodynamic diameter) with a 15 min time resolution and formaldehyde, hydrogen peroxide and methyl hydroperoxide measured with 10 min time resolution. Continuous measurements with response times of ~90 s were also made of Hydrogen Peroxide and Formaldehyde on the NOAA Twin Otter Aircraft. Measurements at the Sydney site were made from April 26 through May 31st. Data and findings related to the atmospheric composition of the Tampa Bay Airshed will be presented. The pattern of HCl, particulate nitrate and nitric acid concentrations strongly suggest that at least in part, HCl formation is related to nitrate formation. This postulated reaction of nitric acid on coarse sea salt particles constitutes a dominant pathway for nitrogen deposition. The appearance of gaseous HCl is inversely related to relative humidity; this may be expected as well. The sulfate/ammonium equivalent ratio in equivalents is almost always greater than unity during weekdays suggesting that sulfate is only partially neutralized by ammonium. However, on weekends the same ratio approaches unity. The acidic nature of the fine particles in addition to the abundance of coarse sea salt NaCl also explains the almost exclusive presence of nitrate in the coarse PM fraction. Finally representative patterns of gases and particles will also be presented along with occasional observation of plumes from coal power plants, which passed directly over the Sydney site.

    The Albion Street Centre was established in 1985 as an HIV testing and early management center. More than 22,000 people have been screened for HIV and other blood-borne infections at the Centre, and approximately 3,600 people with HIV/AIDS have been managed there. Approximately 1,600 patients with various stages of HIV disease are currently managed at the Centre by a staff of 60 health care professionals and about 1,000 volunteers. The Albion Street Centre's computer database began recording selected demographic, epidemiologic, clinical, and laboratory characteristics when the first patient presented in 1985. Since then, the complexity and utilization of the database has increased in parallel with improvement in the understanding of the natural history and pathogenesis of HIV infection. Over 100 peer-reviewed publications and presentations have been produced from the database and 45 clinical trials have used the database to identify potential subjects. All data are de-identified and are protected by multiple password codes. Approximately 700 variables are collected from each HIV-positive patient at the initial visit to the Centre and up to 200 variables are added at each subsequent routine clinic visit. The variables collected include the following: standard epidemiologic characteristics; transmission and behavioral parameters, clinical signs and symptoms; laboratory test results; treatments; nutritional history; body composition parameters; psychological assessment results; and management history, including neuropsychological testing. The overall number and characteristics of patients recorded in the database are reported monthly, and are used to plan services, for prevention and educational programs, and as an indicator of the effectiveness of campaigns to encourage HIV-positive people to attend clinics for early management. When these patients have been identified they are invited to participate in the study. Individual patient records are identified and accessed if they meet certain criteria for flagging. For example, patients who have lost more than 5% of their maximal weight are flagged and referred to the dietician for assessment. Further uses for the database are to identify cohorts of patients who are seroconverters and to follow their natural history-the Centre has over 250 patients for whom a documented HIV-positive test has been obtained within 12 months of a documented HIV-negative test; to investigate clinical observations that have been associated with particular drug therapy, e.g., investigation of the reported association between the use of valacyclovir and the thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS)-like complex showed patients with terminal-stage AIDS demonstrated this syndrome independently of their therapy and probably as a consequence of multiorgan failure; and to document the relationship between nutritional intervention and survival, for which use of the database enabled an historical cohort that matched the cases under investigation to be selected. In conclusion, the database is a dynamic and integral part of the assessment, management, and research program of the Albion Street Centre, where it is used by all professional staff. PMID:9586650

    The aim of this study was to review the incidence, indication, management and complications of peripartum hysterectomy (PH) in a tertiary level hospital over a decade. A retrospective review of all cases of PH performed at Westmead Hospital, Western Sydney, 2003-2012, was undertaken. PH was defined as hysterectomy performed after 20 weeks' gestation or any time after delivery but within 6 weeks' postpartum ( Awan et al. 2011 ). There were 56 cases of peripartum hysterectomy of 46,177 births, a rate of 1.22 per 1,000 births. The most common indication for PH was morbid adherence of the placenta (58.2%) followed by uterine atony. Having a history of both caesarean section and placenta praevia is highly associated with a morbidly adherent placenta in the index pregnancy (p = 0.002). The most common complication was coagulopathy followed by febrile illness and urinary tract injury. Our data showed previous caesarean section and placenta praevia to be associated with abnormal placentation, the leading indication for PH. Since there is an association between a planned caesarean hysterectomy and reduced amount of estimated blood loss and blood transfused, the knowledge of placentation and adequate preoperative planning and consideration for elective hysterectomy could be beneficial. The morbidity associated with PH is considerable. PMID:25264917

    Norovirus is the commonest cause of acute gastrointestinal disease and is the main aetiological agent of outbreaks of gastroenteritis, particularly in semi-closed environments. Norovirus infections in England typically peak between December and March each year. The most commonly detected norovirus strains belong to the genetically diverse genogroup-II genotype-4 (GII-4) genocluster and in the previous two norovirus winter seasons the majority of GII-4 strains in circulation worldwide have been genetically similar to the GII-4 strain New Orleans 1805/2009/USA. At the beginning of the 2012/13 season a genetically distinct GII-4 strain (Sydney 2012/NSW0514/2012/AU) was described which emerged worldwide during the winter of 2012/13. Here we describe the emergence of norovirus strains genetically related to Sydney2012 in England during the 2012/13 season to replace NewOrleans2009 strains as the most commonly detected variant of GII-4 norovirus in England. Furthermore, we demonstrate that whilst the emergence of Sydney2012 coincided with an early peak in the number of norovirus outbreaks, there was not an overall increase in norovirus activity compared to the previous season. Finally, we show that the Sydney2012 strain is associated with distinct genetic changes compared to the NewOrleans2009 strain, and these changes may have contributed to the emergence of the Sydney2012 strain.

    Coupled global, regional and chemical transport models are now being used with relative-risk functions to determine the impact of climate change on human health. Studies have been carried out for global and regional scales, and in our paper we examine the impact of climate change on ozone-related mortality at the local scale across an urban metropolis (Sydney, Australia). Using three coupled models, with a grid spacing of 3 km for the chemical transport model (CTM), and a mortality relative risk function of 1.0006 per 1 ppb increase in daily maximum 1-hour ozone concentration, we evaluated the change in ozone concentrations and mortality between decades 1996–2005 and 2051–2060. The global model was run with the A2 emissions scenario. As there is currently uncertainty regarding a threshold concentration below which ozone does not impact on mortality, we calculated mortality estimates for the three daily maximum 1-hr ozone concentration thresholds of 0, 25 and 40 ppb. The mortality increase for 2051–2060 ranges from 2.3% for a 0 ppb threshold to 27.3% for a 40 ppb threshold, although the numerical increases differ little. Our modeling approach is able to identify the variation in ozone-related mortality changes at a suburban scale, estimating that climate change could lead to an additional 55 to 65 deaths across Sydney in the decade 2051–2060. Interestingly, the largest increases do not correspond spatially to the largest ozone increases or the densest population centres. The distribution pattern of changes does not seem to vary with threshold value, while the magnitude only varies slightly. PMID:24419047

    This research provided background for surveys and interviews in later stages of a 3 part project. It aimed to identify, from secondary research, sociodemographic characteristics which tend to support registered clubs and their machine gaming activities in the Sydney Statistical Division. Using multiple methods including Pearson's Product Moment correlation, Principal Components factor analysis, and stepwise regression, the study profiled Sydney populations which spend highly on gaming machines. The most important sociodemographic predictors of Sydney statistical local areas where per capita gaming machine expenditure is high are large proportions of the adult resident population who were born in Malta, Greece, Lebanon, China, Italy, Vietnam, Yugoslavia, India or the Philippines; have no vocational or tertiary qualifications; or are unemployed.

  14. Taking Charge: Walter Sydney Adams and the Mount Wilson Observatory

    The growing preeminence of American observational astronomy in the first half of the 20th century is a well-known story and much credit is given to George Ellery Hale and his skill as an observatory-building entrepreneur. But a key figure who has yet to be discussed in great detail is Walter Sydney Adams (1876-1956), Hale's Assistant Director at Mount Wilson Observatory. Due to Hale's illnesses, Adams was Acting Director for much of Hale's tenure, and he became the second Director of Mount Wilson from 1923 to 1946. Behind his New England reserve Adams was instrumental in the growth of Mount Wilson and thus American astronomy in general. Adams was hand-picked by Hale to take charge of stellar spectroscopy work at Yerkes and Mount Wilson and the younger astronomer showed tremendous loyalty to Hale and Hale's vision throughout his career. As Adams assumed the leadership role at Mount Wilson he concentrated on making the observatory a place where researchers worked with great freedom but maintain a high level of cooperation. This paper will concentrate on Adams's early years and look at his growing relationship with Hale and how he came to be the central figure in the early history of Mount Wilson as both a solar and stellar observatory. His education, his years at Dartmouth and Yerkes (including his unfortunate encounter with epsilon Leonis), and his formative years on Mount Wilson are all important in learning how he shaped the direction of Mount Wilson and the development of American astronomy in the first half of the 20th century. This latter history cannot be complete until we bring Adams into better focus.

    Norovirus is the major cause of acute gastroenteritis worldwide. Between November 2012 and June 2013, 1718 stool samples were requested for norovirus antigen testing in the metropolitan areas of South Korea, and 91 samples were genotyped. The norovirus antigen-positive rate peaked at 52.8% in December 2012. [corrected]. A novel norovirus GII.4 variant, GII.4 Sydney 2012, was the most frequently found genotype (60.4%) during this period. This study demonstrates that norovirus activity increased during the winter of 2012-2013 in South Korea and that norovirus GII.4 Sydney 2012 was the cause of the norovirus epidemic during this period.

    The accurate prediction of sudden large changes in the maximum temperature from one day to the next remains one of the major challenges for operational forecasters. It is probably the meteorological parameter most commonly verified and used as a measure of the skill of a meteorological service and one that is immediately evident to the general public. Marked temperature changes over a short period of time have widespread social, economic, health and safety effects on the community. The first part of this paper describes a 40-year climatology for Sydney, Australia, of sudden temperature rises and falls, defined as maximum temperature changes of 5°C or more from one day to the next, for the months of September and October. The nature of the forecasting challenge during the period of the Olympic and Paralympic Games to be held in Sydney in the year 2000 will be described as a special application. The international importance of the accurate prediction of all types of significant weather phenomena during this period has been recognized by the World Meteorological Organisation's Commission for Atmospheric Science. The first World Weather Research Program forecast demonstration project is to be established in the Sydney Office of the Bureau of Meteorology over this period in order to test the ability of existing systems to predict such phenomena. The second part of this study investigates two case studies from the Olympic months in which there were both abrupt temperature rises and falls over a 4-day interval. Currently available high resolution numerical weather prediction systems are found to have significant skill several days ahead in predicting a large amount of the detail of these events, provided they are run at an appropriate resolution. The limitations of these systems are also discussed, with areas requiring further development being identified if the desired levels of accuracy of predictions are to be reliably delivered. Differences between the predictability of sudden temperature rises and sudden temperature falls are also explored.

    A set of seven principles (the 'Sydney Principles') was developed by an International Obesity Taskforce (IOTF) Working Group to guide action on changing food and beverage marketing practices that target children. The aim of the present communication is to present the Sydney Principles and report on feedback received from a global consultation (November 2006 to April 2007) on the Principles. The Principles state that actions to reduce marketing to children should: (i) support the rights of children; (ii) afford substantial protection to children; (iii) be statutory in nature; (iv) take a wide definition of commercial promotions; (v) guarantee commercial-free childhood settings; (vi) include cross-border media; and (vii) be evaluated, monitored and enforced. The draft principles were widely disseminated and 220 responses were received from professional and scientific associations, consumer bodies, industry bodies, health professionals and others. There was virtually universal agreement on the need to have a set of principles to guide action in this contentious area of marketing to children. Apart from industry opposition to the third principle calling for a statutory approach and several comments about the implementation challenges, there was strong support for each of the Sydney Principles. Feedback on two specific issues of contention related to the age range to which restrictions should apply (most nominating age 16 or 18 years) and the types of products to be included (31% nominating all products, 24% all food and beverages, and 45% energy-dense, nutrient-poor foods and beverages). The Sydney Principles, which took a children's rights-based approach, should be used to benchmark action to reduce marketing to children. The age definition for a child and the types of products which should have marketing restrictions may better suit a risk-based approach at this stage. The Sydney Principles should guide the formation of an International Code on Food and Beverage Marketing to Children. PMID:18510788

    The 2010 7th International Melanoma Congress sponsored by the Society for Melanoma Research and held in Sydney, Australia, was held together with the International Melanoma and Skin Cancer Centers group and the International Melanoma Pathology Study Group. As a consequence, there were over 900 registrants that included a wide range of clinicians (surgeons, medical oncologists, dermatologists) specialising in the management of melanoma as well as scientists and students carrying out laboratory-based research in melanoma. There was a general consensus that this grouping of clinicians, pathologists and scientists was mutually advantageous and plans are afoot to continue this grouping in future meetings. The meeting was dominated by the advances being made in treatment of melanoma with selective BRAF inhibitors but interest in epithelial mesenchymal transition and phenotypic changes in melanoma was apparent in many of the talks. The authors have attempted to capture many of the new developments in melanoma research but apologize to those speakers and poster presenters who had equally important findings not captured in these summaries.

  2. Fire effects on reservoir water quality: lessons from the 2013 Sydney wildfires

    Unseasonally, early and severe forest fires burnt ca 10,000 ha of dry sclerophyl eucalypt forest in Oct. 2013 near Sydney (NSW, Australia). The fire affected parts of the Nepean catchment, which contributes to the greater Sydney water supply system. The spatial extent and severe nature of the burn raised concerns about the risk of water contamination from post-fire erosion. An investigation was launched with the aim to determine (i) the total loads of ash and loose charred topsoil that are particular susceptible to erosion, (ii) their chemical composition regarding constituents relevant to water quality, and (iii) the potential impacts of post-fire erosion events transferring some of this material into the reservoir. Sampling was carried out at a ridge in the Nepean catchment with a relatively homogeneous vegetation species composition, fuel load and soil characteristics, but with a range of burn severities, resulting from wind-driven differences in fire behaviour. This allowed sampling of three replicate sites each, with 30 sampling points each, for extreme, moderate-severe, and low burn severities, including also soil and litter sampling at a long-unburned control site. Burn severity was determined using the differenced normalised burn ratio (dNBR) obtained from satellite images immediately before (1 day) and after (1 week) the fire, validated by on site determination of fuel consumption completeness. Between the fire and the sampling campaign, rainfall was very limited so that there had been no significant redistribution of ash and loose charred topsoil by water erosion. The ash and loose charred topsoil were consistently wettable and the underlying uncharred soil highly water repellent at all sites and sampling points irrespective of burn severity. The total loads of ash and loose charred topsoil increased substantially with burn severity and changed in composition from comprising mainly charred litter and charcoal at low severity sites to charred litter, charcoal, mineral ash and charred mineral soil at extreme severity sites. Field sampling had just been completed at the time of producing this abstract. At the time of presentation, we expect to present (i) the total loads (t/ha) of ash and loose charred topsoil for each burn severity class; (ii) data on detailed chemical characterisation of the sampled materials including background values for litter and long-unburned soil; (iii) a spatially distributed estimation of ash and loose charred topsoil for the study catchment; and (iv) potential implications for water quality impacts based on a series of post-fire rainfall and erosion scenarios. Wider implications for water quality impacts in eucalypt forest catchments in relation to fuel loads and fire behaviour will also be discussed.

    Wildfire is a recurring event which has been acknowledged by the literature to impact the hydrological cycle of a catchment. Hence, wildfire may have a significant impact on water yield levels within a catchment. In Australia, studies of the effect of fire on water yield have been limited to obligate seeder vegetation communities. These communities regenerate from seed banks in the ground or within woody fruits and are generally activated by fire. In contrast, the Sydney Basin is dominated by obligate resprouter communities. These communities regenerate from fire resistant buds found on the plant and are generally found in regions where wildfire is a regular occurrence. The 2001/2002 wildfires in the Sydney Basin provided an opportunity to investigate the impacts of wildfire on water yield in a number of catchments dominated by obligate resprouting communities. The overall aim of this study was to investigate whether there was a difference in water yield post-wildfire. Four burnt subcatchments and 3 control subcatchments were assessed. A general additive model was calibrated using pre-wildfire data and then used to predict post-wildfire water yield using post-wildfire data. The model errors were analysed and it was found that the errors for all subcatchments showed similar trends for the post-wildfire period. This finding demonstrates that wildfires within the Sydney Basin have no significant medium-term impact on water yield.

    The newly emerged Norovirus (NoV) Sydney 2012 strain has been sweeping all over the world, causing acute non-bacterial gastroenteritis in adults and children. Due to a lack of cell culture system, virus like particles (VLPs) has been assembled and used as vaccine candidates in preclinical and clinical studies. Expression of the major capsid protein of NoVs using recombinant baculovirus expression system in Sf9 cells leads to formation of VLPs that are morphologically and antigenically similar to true virions. In this study, VLPs were successfully produced using the VP1 of Sydney-2012-like strain and its immunogenicity was evaluated by different routes and its capability in inducing mucosal immune responses in the presence and absence of adjuvants in BALB/c mice. Administration of NoV VLPs in the presence of Al(OH)3 or monophosphoryl lipid A (MPL-A) led to high titers of VLP-specific IgG antibodies. Administration of VLPs orally in the presence of cholera toxin subunit B (CTB) didn't enhance mucosal immune response as less fecal IgA positive mice were observed when compared with those given VLPs only. Our study represents the first immunogenicity study of VLPs derived from current pandemic Sydney 2012 strain and which might have implications in the development of NoVs vaccine in china.

    This study analyzes data on all female sex workers who attended the Sydney Sexual Health Center for a first visit for a sexually transmitted disease (STD) screening during June 1, 1991, and May 31, 1993. International sex workers were identified as women who do not speak English at home and were born outside Australia. Diseases were confirmed clinically, by specimen or culture or by antibody or serological tests. Results apply to 91 local and 123 international prostitutes. 47% of international prostitutes and 34% of local prostitutes were aged 21-25 years. Most international sex workers spoke Thai or a Chinese dialect. 10% of local prostitutes were born in Asia. 90% of international prostitutes were born in Thailand, Malaysia, or China. Local prostitutes were better educated. 7% of the local prostitutes and none of the international sex workers had a history of injectable drug use. Local prostitutes tended to use condoms for birth control, and international prostitutes tended to use oral contraceptives. One international prostitute tested HIV positive. 1 in 7 international prostitutes had gonorrhea and the same proportion had chlamydia. Viral STDs (chronic hepatitis B, HIV infection, and genital warts) were more prevalent, but uncommon among international prostitutes. More international prostitutes had multiple STDs. 79 international sex workers and only 9 local sex workers had an STD. 47% of international sex workers and only 10% of local sex workers had worked overseas as a prostitute in the preceding 12 months. Over half of local sex workers and only 8% of international sex workers consistently used condoms. Failure to use condoms was associated with being an international sex worker. Inconsistent use of condoms among local prostitutes was related to increased age. PMID:8655167

    A major dust storm transgressed over southeastern Australia in September 2009 and continued as far as northern Queensland [to the north], New Zealand and New Caledonia [to the east] . We analysed samples of the dust for organic compounds, its microbiological composition, pollen, trace and rare earth elements as well as Sr and Nd isotopes. Grain size analysis was also performed on some of the samples. We also obtained information on the meteorological conditions that led to the large dust plume and its pathway. Our geochemical fingerprinting allowed us to determine the origin of the dust, and this was confirmed by meteorological observations and satellite imagery. As the pathway of the dust plume went over the city of Canberra, located to the southwest of Sydney, we were able to collect samples of dust that fell with rain, and the surprise was that the geochemical composition of the dust varied with time [and dust fall], identifying that as the dust plume transgressed over the landscape, it picked up additional material that was compositionally different from its point of origin. We also compared our data with those obtained from another major dust event that affected Canberra in October 2002, and a number of important differences are noted, particularly with respect of the microbiological composition of the dust, and its chemical composition.

    2010-08-01

    Concentrations of ultrafine (<0.1 ?m) particles (UFPs) and PM 2.5 (<2.5 ?m) were measured whilst commuting along a similar route by train, bus, ferry and automobile in Sydney, Australia. One trip on each transport mode was undertaken during both morning and evening peak hours throughout a working week, for a total of 40 trips. Analyses comprised one-way ANOVA to compare overall (i.e. all trips combined) geometric mean concentrations of both particle fractions measured across transport modes, and assessment of both the correlation between wind speed and individual trip means of UFPs and PM 2.5, and the correlation between the two particle fractions. Overall geometric mean concentrations of UFPs and PM 2.5 ranged from 2.8 (train) to 8.4 (bus) × 10 4 particles cm -3 and 22.6 (automobile) to 29.6 (bus) ?g m -3, respectively, and a statistically significant difference ( p < 0.001) between modes was found for both particle fractions. Individual trip geometric mean concentrations were between 9.7 × 10 3 (train) and 2.2 × 10 5 (bus) particles cm -3 and 9.5 (train) to 78.7 (train) ?g m -3. Estimated commuter exposures were variable, and the highest return trip mean PM 2.5 exposure occurred in the ferry mode, whilst the highest UFP exposure occurred during bus trips. The correlation between fractions was generally poor, and in keeping with the duality of particle mass and number emissions in vehicle-dominated urban areas. Wind speed was negatively correlated with, and a generally poor determinant of, UFP and PM 2.5 concentrations, suggesting a more significant role for other factors in determining commuter exposure.

    Biological introductions can alter the ecology of local assemblages and are an important driver of global environmental change. The first step towards understanding the impact of a non-indigenous species is to study its distribution and associations in the invaded area. In Sydney Harbour, the non-indigenous isopod Cirolana harfordi has been reported in densities up to 0.5 individuals per cm2 in mussel-beds. Abundances of this species have, however, been largely overlooked in other key habitats. The first aim of this study was to evaluate the abundances and distribution of C. harfordi across different habitats representative of Sydney Harbour. Results showed that C. harfordi occurred in oyster and mussel-beds, being particularly abundant in oyster-beds. We also aimed to determine the role of C. harfordi as a predator, scavenger and detritus feeder by investigating the relationships between densities of C. harfordi and (i) the structure of the resident assemblages, and (ii) deposited organic matter in oyster-beds. Densities of C. harfordi were not related to the structure of the assemblages, nor amounts of deposited organic matter. These findings suggested little or no ecological impacts of C. harfordi in oyster-beds. These relationships may, however, affect other variables such as growth of individuals, or be disguised by high variability of assemblages among different locations. Future studies should, therefore, test the impacts of C. harfordi on the size of organisms in the assemblage and use manipulative experiments to control for spatial variation. This study is the first published work on the ecology of the invasion of C. harfordi and provides the starting-point for the study of the impacts of this species in Sydney Harbour. PMID:24466227

    A mesoscale petrophysics and lithological logging study has been carried out on 413 core samples of the 623m thick Narrabeen Group succession penetrated by the Eveleigh No. 1 diamond drillhole. Mass properties, magnetic susceptibilities, and electrical estimates of mobile salt (EC 1:5 tests) were measured. A physical properties analysis posits a 3-fold subdivision of the succession: basal fluvio-deltaic and alluvial, upper lacustrine, and topmost fluvio-deltaic. Each division has cyclic sedimentation but from different provenances. The analysis has proved useful in the correlation of the Narrabeen Group present in a series of drillholes in the eastern part of the exposed Sydney Basin.

    2003-04-01

    The undoubted success of the SMU as a specialist multidisciplinary melanoma treatment center has clearly been the result of many factors. Perhaps chief among these was the vision and commitment that led Dr. Milton to establish it in the first place, and the sharing of that vision and commitment by those who were associated with him and by those who joined the SMU later. Another vitally important element, however, has been the continuing sense of unity and purpose fostered by the weekly SMU clinical meetings, which are truly multidisciplinary, in which all staff are encouraged to participate, and at which the desirability of adherence to agreed, evidence-based treatment guidelines is emphasized. A further influential factor has been the SMU's strong commitment to clinical and basic research as a concomitant of high quality clinical care, with stimulation, encouragement, and advice provided at its monthly multidisciplinary research meetings, where all current and proposed clinical and laboratory studies are discussed. As a result of these activities, despite an ever-increasing number of people working within it, the SMU has been able to present to referring doctors, to patients, and to the community a unified commitment to the best possible patient care and to high quality clinical and laboratory research. These groups have responded by recognizing the SMU as the major referral center for melanoma in Australia, as evidenced by the steadily increasing number of patients referred to it for treatment each year. Melanoma is a more pressing health problem in Australia than elsewhere, because it is the third most common cancer in women (after breast cancer and colorectal cancer), and the fourth most common cancer in men (after prostate cancer, colorectal cancer, and lung cancer). Nevertheless the experiences of the SMU as a large multidisciplinary melanoma treatment center are likely to have relevance and application in other countries, where the incidence of melanoma is lower but continues to rise, and may within a few years approach rates currently recorded in Australia.

    This study reviews firearm-related deaths (homicidal, suicidal and accidental) from 1994 to 2003 in the Western Sidney area, Australia, serviced by the Westmead Department of Forensic Medicine, in order to document the features of the cases and to assess the effect of the introduction of the NSW Firearms Act in 1996. There were 211 fatalities involving firearms (1.8% of all of the Coroner's cases for the period); firearm deaths were classified as homicide (75), suicide (134) or accidental (2). There was a clear peak of homicide deaths by firearm in the 20-29 age group, whereas the suicide peak was broad, spanning the ages 20-69 years. More suicides occurred at home than homicides and a higher proportion of suicides were by rifle than homicides, which favoured hand guns. Entry wounds in suicides mostly involved the head, with the chest being the commonest entry site in homicides. The only statistically significant trend was for an increase in the number of firearm-related suicides in males, comparing the number of deaths pre- and post-firearm law introduction. The study includes reports of two suicides by unusual weapons: a home-made pipe gun and a spear gun. PMID:25869264

    Introduction There are large Pacific island communities in western and south-western Sydney, New South Wales, Australia. In 2011 and 2012, measles outbreaks disproportionally affected children and youth within these communities. The objectives of this study were to explore barriers to immunization in a Pacific island community from the perspectives of community members and health professionals and to conduct a pilot programme whereby immunization catch-up clinics were held in a Samoan church in western Sydney. Methods Interviews were conducted with Pacific island community members (n = 12) and health professionals connected with the Pacific island community (n = 7) in 2013. A partnership with a local Samoan church was established to provide an accessible venue for immunization catch-up clinics. Results Among the community members there were high levels of belief in the importance of immunization and a positive view regarding the protection offered by immunization. A key barrier reported by community members was being busy and therefore having limited time to get children immunized. The important role of the church within the community was emphasized in the interviews, and as a result, two immunization catch-up clinics were held in a Samoan church in western Sydney. The age range of attendees was 7–33 years. A total of 31 measles, mumps and rubella doses and 19 meningococcal C doses were given during the two clinics. Discussion The outcomes of the interviews and the subsequent clinics highlighted the potential of churches as a venue for providing public health interventions such as catch-up immunization.

    Aquaculture has long been seen as a sustainable solution to some of the world's growing food shortages. However, experience over the past 50 years indicates that infectious diseases caused by viruses, bacteria, and eukaryotes limit the productivity of aquaculture. In extreme cases, these types of infectious agents threaten the viability of entire aquaculture industries. This article describes the threats from infectious diseases in aquaculture and then focuses on one example (QX disease in Sydney rock oysters) as a case study. QX appears to be typical of many emerging diseases in aquaculture, particularly because environmental factors seem to play a crucial role in disease outbreaks. Evidence is presented that modulation of a generic subcellular stress response pathway in oysters is responsible for both resistance and susceptibility to infectious microbes. Understanding and being able to manipulate this pathway may be the key to sustainable aquaculture. PMID:24795701

    To describe the epidemiological characteristics of norovirus (NOV) associated acute gastroenteritis in Shanghai and characterize the evolution pattern of circulating strains. From March 2012 to February 2013, 502 stool specimens were collected from adult (> or = 16 years) outpatients who visited either of the two sentinel hospitals in Shanghai for acute gastroenteritis. Molecular detection and genotyping of NoV were performed and the phylogenetic relationship of the circulating strains has also been comprehensively analyzed. The epidemics level of GI NoV was low throughout the surveillance period, with the positive rate of 3.78% (19 cases), and no seasonality of GI NoV infection could be distinguished. For GII genogroup, higher epidemics in adults in Shanghai, with the detection rate of 17.13% (86 cases), were observed. And relatively high epidemics of GII NoV infection were spotted between October and December in 2012. The frequency of NoV associated acute gastroenteritis in older people is significantly higher than that in young individuals (P < 0.05). Sequencing and genotyping analysis revealed that the high epidemics of GII NoV infection between October and December in 2012 is associated with the emergence of a novel GII.4 norovirus strain, termed Sydney_2012. Sequence analysis also demonstrated that this was a recombinant virus between a GII.e polymerase and GII.4 capsid, which has also been the dominant circulating strain in Shanghai. In 2012, a new GII.4 variant, termed Sydney_2012, emerged in Shanghai and caused high epidemics of acute gastroenteritis during late autumn and winter. PMID:24520766

    Two hundred long-term cannabis users (58% male) were interviewed on their characteristics and experience of use. Respondents had been regularly using cannabis for an average of 11 years and more than half used daily (56%). The most common route of administration was in a waterpipe, and nearly all (93%) smoked the flowering heads ot the plant. One in 5 (21%) had a cannabis-related conviction. The benefits of use were perceived to be its relaxing, mood-enhancing effects, and its ability to alter consciousness. The most commonly cited negative aspects of use were cost, negative psychological effects and legal status. Polydrug use was common, with alcohol and tobacco almost universally used on a regular basis. More than half the drinkers in the sample were consuming alcohol at hazardous or harmful levels.

    2015-05-01

    Marteilia sydneyi (Phylum Paramyxea, Class Marteiliidea, Order Marteiliida) (the causative agent of QX disease) is recognised as the most severe parasite to infect Saccostrea glomerata, the Sydney rock oyster, on the east coast of Australia. Despite its potential impact on industry (>95% mortality), research towards lessening these effects has been hindered by the lack of an experimental laboratory model of infection as a consequence of our incomplete understanding of the life cycle of this parasite. Here, we explored the presence of this parasite in hosts other than a bivalve mollusc from two study sites on the Hawkesbury River, New South Wales, Australia. We employed PCR-based in situ hybridisation and sequence analysis of a portion of the first internal transcribed spacer of rDNA in an attempt to detect M. sydneyi DNA in 21 species of polychaete worm. Marteilia DNA was detected in 6% of 1247 samples examined by PCR; the analysis of all amplicons defined one distinct sequence type for first internal transcribed spacer, representing M. sydneyi. Of the polychaete operational taxonomic units test-positive in PCR, we examined 116 samples via in situ hybridisation DNA probe staining and identified M. sydneyi DNA in the epithelium of the intestine of two specimens of Nephtys australiensis. Two differing morphological forms were identified: a 'primordial' cell that contained a well-defined nucleus but had little differentiation in the cytoplasm, and a 'plasmodial' cell that showed an apparent syncytial structure. This finding represents the first known record of the identification of M. sydneyi being parasitic in an organism other than an oyster, and only the third record of any species of Marteilia identified from non-molluscan hosts. Future work aims at determining if N. australiensis and S. glomerata are the only hosts in the life cycle of this paramyxean, and the development of experimental models to aid the production of QX disease-resistant oysters.

  8. Changing Water Depths in the Eastern Part of Sydney Harbour due to Human Impacts

    2014-12-01

    Sydney Harbour has been significantly modified by human impacts from the start of the European settlement in 1788. Land clearing has accelerated soil erosion, resulting in increased sedimentation. Dredging has deepened many areas to accommodate ever-larger ships. In this paper a GIS method is used to map bathymetric changes in the eastern part of the harbour from 1903 to more recently. Dredged areas are apparent in the entrance and in wharfage areas, while sedimentation is most marked around the deepest section, which is well inside the harbour itself. In this latter region sediment has built up considerably, to over 3 m in some locations, and ship-induced motions appear to have had an impact. Despite these changes the overall depth of the eastern part of the harbour has changed little. This work is of interest to maritime archaeologists because it brings out the types of processes by which sediments can accumulate and be removed thus altering a harbour's seabed and potentially burying, exposing or erasing archaeological sites and artefacts.

  9. Evaluation of AirXpanders for Breast Reconstruction: Early Experience from Sydney

    PubMed Central

    Hsieh, Frank

    2015-01-01

    Aim: Two-staged prosthetic breast reconstruction has become a popular option involving a series of saline injections to expanders to create a pocket large enough for a permanent implant. This, however, requires frequent visits to the surgeon and numerous needle pricks with potential infection risk. A new form of tissue expander, the AirXpanders, has recently been trialed in Perth and the United States. It uses a remote-controlled release of compressed CO2 where needle punctures are avoided. Methodology: Prospective data were collected on the first 10 patients to have the AirXpanders implant inserted for breast reconstruction at Western Sydney. The implants were inserted subpectorally as the saline expanders, and patients were instructed how to use the remote 4 weeks postoperation. Results: Ten patients (4 immediate and 6 delayed) aged between 30 and 65 (mean, 48.3 years) underwent 14 AirXpanders insertions. One patient passed away due to metastatic malignancy. With the remaining patients, the average period of active expansion was 15.8 days (r, 6–21). The average size of final implant used was 451?g (r, 195–685). The only complications were 2 seromas. Conclusion: Our early results are consistent with the Perth trial. The new AirXpanders is safe to use and able to achieve satisfactory tissue expansion faster than saline expander. It also has the advantage of patient self-controlled without the need for multiple medical reviews and needle punctures. PMID:26495208

  10. Quantitative proteomics of heavy metal stress responses in Sydney rock oysters.

    2012-03-01

    Currently, there are few predictive biomarkers in key biomonitoring species, such as oysters, that can detect heavy metal pollution in coastal waterways. Several attributes make oysters superior to other organisms for positive biomonitoring of heavy metal pollution. In particular, they are filter feeders with a high capacity for bioaccumulation. In this study, we used two proteomics approaches, namely label-free shotgun proteomics based on SDS-PAGE gel separation and gas phase fractionation, to investigate the heavy metal stress responses of Sydney rock oysters. Protein samples were prepared from haemolymph of oysters exposed to 100 ?g/L of PbCl(2), CuCl(2), or ZnCl(2) for 4 days in closed aquaria. Peptides were identified using a Bivalvia protein sequence database, due to the unavailability of a complete oyster genome sequence. Statistical analysis revealed 56 potential biomarker proteins, as well as several protein biosynthetic pathways to be greatly impacted by metal stress. These have the potential to be incorporated into bioassays for prevention and monitoring of heavy metal pollution in Australian oyster beds. The study confirms that proteomic analysis of biomonitoring species is a promising approach for assessing the effects of environmental pollution, and our experiments have provided insights into the molecular mechanisms underlying oyster stress responses.

    Observations of the southern Cepheid l Car to yield the mean angular diameter and angular pulsation amplitude have been made with the Sydney University Stellar Interferometer (SUSI) at a wavelength of 696 nm. The resulting mean limb-darkened angular diameter is 2.990+-0.017 mas (i.e. +-0.6 per cent) with a maximum-to-minimum amplitude of 0.560+-0.018 mas corresponding to 18.7+-0.6 per cent in the mean stellar diameter. Careful attention has been paid to uncertainties, including those in measurements, in the adopted calibrator angular diameters, in the projected values of visibility squared at zero baseline, and to systematic effects. No evidence was found for a circumstellar envelope at 696 nm. The interferometric results have been combined with radial displacements of the stellar atmosphere derived from selected radial velocity data taken from the literature to determine the distance and mean diameter of l Car. The distance is determined to be 525+-26 pc and the mean radius 169+-8R{solar). Comparison with published values for the distance and mean radius show excellent agreement, particularly when a common scaling factor from observed radial velocity to pulsation velocity of the stellar atmosphere (the p-factor) is used.

    OBJECTIVE: To document the injuries sustained by participants in a 1005 km ultramarathon. METHODS: Clinical notes were reviewed on entrants in the 1005 km Sydney to Melbourne ultramarathon. An injury was recorded following self referral by a participant or if the history obtained from the runner or his support crew indicated the likelihood of a significant injury which could have an impact upon performance. RESULTS: 64 injuries were found in 32 runners. The knee (31.3%) and ankle (28.1%) regions were most commonly injured. The most common single diagnosis was retropatellar pain syndrome, and Achilles tendinitis and medial tibial stress syndrome were the next most common injuries. Peritendinitis/tendinitis of the tendons passing under the extensor retinaculum at the ankle, an injury infrequently reported in other sports, was common (19% of all injuries). CONCLUSIONS: The injuries were typically associated with running but 12 (19% of the total) involved the tendons of the muscles of the anterior compartment of the lower leg, and in almost every case the major site of inflammation was at the extensor retinaculum at the anterior aspect of the ankle. This injury appears to be relatively specific to the ultramarathon-"ultramarathoner's ankle". Images p321-a PMID:9015594

    In the current study, we tested the effects of common environmental contaminants (the metals zinc and lead) on gene expression in Sydney rock oysters (Saccrostrea glomerata). Oysters were exposed to a range of metal concentrations under controlled laboratory conditions. The expression of 14 putative stress response genes was then measured using quantitative, real-time (q) PCR. The expression of all 14 genes was significantly affected (p?

    Past studies disagree on the extent to which dissolved or dietary uptake contribute to metal bioaccumulation in the filter-feeding Sydney rock oyster (Saccostrea glomerata) in urbanized estuaries. Although most data support the assumption that fine sediments are a major route of metal uptake in these bivalves, some studies based in the Sydney estuary, Australia, have indicated a poor correlation. In the present study, seawater, sediment and microalgae were radiolabelled with (65)Zn tracer and exposed to S. glomerata to assess the influence of dissolved and dietary sources to Zn bioaccumulation. Oysters in the dissolved-phase uptake experiment (5, 25 and 50 ?g L(-1) (65)Zn for 4 d followed by 21 days of depuration) readily accumulated (65)Zn for all three concentrations with an uptake rate constant of 0.160±0.006 L dry weight g(-1) d(-1). Oysters in the dietary assimilation experiment (1h pulse-feed of either (65)Zn-radiolabelled suspended fine-fraction (<63 ?m) sediment or the microalgae Tetraselmis sp.) accumulated (65)Zn, with assimilation efficiencies of 59 and 67% for fine sediment and microalgae, respectively. The efflux rates were low for the three experiments (0.1-0.5% d(-1)). A bioaccumulation kinetic model predicts that uptake of Zn will occur predominantly through the dietary ingestion of contaminated fine sediment particles and microalgae within the water column, with considerably greater metal bioaccumulation predicted if oysters ingested microalgae preferentially to sediments. However, the model predicts that for dissolved Zn concentrations greater than 40 ?g L(-1), as observed during precipitation events, the uptake of the dissolved phase may contribute ?50% to accumulation. Overall, the results of the present study suggest that all three sources may be important exposure routes to S. glomerata under different environmental conditions, but contributions from dietary exposure will often dominate.

    Global surveillance for norovirus identified in 2012 the emergence of a novel pandemic GII.4 variant, termed Sydney 2012. In Italy, the novel pandemic variant was identified as early as November 2011 but became predominant only in the winter season 2012-2013. Upon sequencing and comparison with strains of global origin, the early Sydney 2012 strains were found to differ from those spreading in 2012-2013 in the capsid (ORF2) putative epitopes B, C and D, segregating into a distinct phylogenetic clade. At least three residues (333, 340 and 393, in epitopes B, C and D, respectively) of the VP1 varied among Sydney 2012 strains of different clades. These findings suggest that the spread of the pandemic variant in Italy during the winter season 2012-2013 was due to the introduction of strains distinct from those circulating at low frequency in the former winter season and that similar strains were also circulating elsewhere worldwide.

    In Sydney, Nova Scotia, from 1901 through 1988 a coke and steel factory operated with no pollution controls, depositing over a million tons of particulate matter and releasing several thousands of tons of coal tar into the estuary. Previously we documented the presence of lead, arsenic and PAHs, in soil above Canadian guidelines, and in house dust in the communities surrounding the site [Lambert, TW, Lane, S. Lead, arsenic, and polycyclic aromatic hydrocarbons in soil and house dust in the communities surrounding the Sydney, Nova Scotia, tar ponds. Environ Health Perspect 2004; 112:35-41.]. In this paper we further the research by documenting and developing community knowledge with a study of resident's observations and experiences of the industrial contamination. We conducted two surveys, a quantitative door-to-door survey and qualitative dust interview, designed to complement each other and bring together the observations and experiences in the different communities to develop the local knowledge. The combined methodology uses techniques from both social and physical science, and was developed with the cooperation of community members. The research supports the proposition that local knowledge adds contextual meaning that complements the physical measurement of environmental contaminants, in order to understand the complex environment in which people live, and the multiple exposure pathways through which they can be affected. Residents in all three communities provided vivid observations and detailed experiences of the industrial pollution in their community and homes. The local knowledge is consistent with our physical data and review of the historical scientific research in Sydney, and supports the inference that the community was adversely impacted by the coke and steel facility. From a justice perspective, the three communities should be equally considered for remediation as part of the 'tar pond remediation policy' rather than the current policy of including only a few streets and houses.

    308 female students from six State high schools in inner metropolitan Sydney responded to self-administered questionnaires on their sex behavior and contraceptive use. Respondents were in their tenth year of school and of mean age 15.6 years. The survey was conducted with no refusals over the period March-June 1991 upon the sample from four coed and two single-sex schools. 18% of the sample reported ever having sexual intercourse, although substantial interschool variation was observed; less than 5% of girls in one school with a predominantly non-English speaking population were sexually experienced, while almost 45% were experienced in another school with a predominantly Anglo-Saxon population. The mean age at first intercourse for the sexually active group was 14.5 years. 72% used condoms at first intercourse, while 17% used no form of contraception. There were no significant differences in the mean ages of sexually active and nonactive girls, nor between the percentage of sexually active girls in coed schools and in single-sex schools. 25 girls had ever had a total of one sex partner, 27 had 2-5, and two had more than five. The condom is the most commonly used form of contraception, with 38% of sexually active girls using condoms every time. The rest of the girls used them either occasionally or not at all. Oral contraceptive pills (OCP) were used by less than 15% of the sexually active group, with effective contraception overall used by only 43% of the group. Effective contraception is defined as either condom use during every act of sexual intercourse during the preceding six months or daily compliance with the OCP. Eight subjects used no contraception at all during the preceding six months. These findings indicate the need for more education targeted to adolescents and health professionals, especially general practitioners. PMID:12318952

    Previous work suggests that larvae from Sydney rock oysters that have been selectively bred for fast growth and disease resistance are more resilient to the impacts of ocean acidification than nonselected, wild-type oysters. In this study, we used proteomics to investigate the molecular differences between oyster populations in adult Sydney rock oysters and to identify whether these form the basis for observations seen in larvae. Adult oysters from a selective breeding line (B2) and nonselected wild types (WT) were exposed for 4 weeks to elevated pCO2 (856 ?atm) before their proteomes were compared to those of oysters held under ambient conditions (375 ?atm pCO2 ). Exposure to elevated pCO2 resulted in substantial changes in the proteomes of oysters from both the selectively bred and wild-type populations. When biological functions were assigned, these differential proteins fell into five broad, potentially interrelated categories of subcellular functions, in both oyster populations. These functional categories were energy production, cellular stress responses, the cytoskeleton, protein synthesis and cell signalling. In the wild-type population, proteins were predominantly upregulated. However, unexpectedly, these cellular systems were downregulated in the selectively bred oyster population, indicating cellular dysfunction. We argue that this reflects a trade-off, whereby an adaptive capacity for enhanced mitochondrial energy production in the selectively bred population may help to protect larvae from the effects of elevated CO2 , whilst being deleterious to adult oysters.

    Industrial waste, sewage outfall and storm water run-off are potential anthropogenic sources of mercury to Sydney beaches. Children playing on these beaches are possibly at risk of exposure to mercury in beach sand through the ingestion pathway. As part of an investigation into this risk samples were collected from various locations along 7 of Sydney's beaches where children typically would be exposed. Samples were dried and the sand fraction (i.e. >63 µm and <2 mm) analysed for total mercury using a Direct Mercury Analyser (DMA-80) methodology. Risk of Exposure to mercury was assessed based on published estimates of daily ingestion of soil by children and Health Canada's guideline of 105 ng Hg kg-1 BW d-1 exposure threshold. For the beaches sampled concentrations of total mercury in beach sand ranged from 0.6 to 58 ppb. The maximum concentrations of total mercury in beach sand were observed on Beach 6, in the vicinity of five storm water runoff sources. Daily mercury intake values were determined for two commonly used published values for daily ingestion of soil by children of 0.2 g soil d-1 and 1.75 g soil d-1. Results to date show the maximum daily intake calculated using an average child weight of 13 kg to be 7.8 ng Hg kg-1 BW d-1, well below the currently accepted daily intake threshold of 105 ng Hg kg-1 BW d-1.

  20. A proposed origin for fossilized Pennsylvanian plant cuticles by pyrite oxidation (Sydney Coalfield, Nova Scotia, Canada)

    Fossilized cuticles, though rare in the roof rocks of coal seam in the younger part of the Pennsylvanian Sydney Coalfield, Nova Scotia, represent nearly all of the major plant groups. Selected for investigation, by methods of Fourier transform infrared spectroscopy (FTIR) and elemental analysis, are fossilized cuticles (FCs) and cuticles extracted from compressions by Schulze's process (CCs) of Alethopteris ambigua. These investigations are supplemented by FTIR analysis of FCs and CCs of Cordaites principalis, and a cuticle-fossilized medullosalean(?) axis. The purpose of this study is threefold: (1) to try to determine biochemical discriminators between FCs and CCs of the same species using semi-quantitative FTIR techniques; (2) to assess the effects chemical treatments have, particularly Schulze's process, on functional groups; and most importantly (3) to study the primary origin of FCs. Results are equivocal in respect to (1); (2) after Schulze's treatment aliphatic moieties tend to be reduced relative to oxygenated groups, and some aliphatic chains may be shortened; and (3) a primary chemical model is proposed. The model is based on a variety of geological observations, including stratal distribution, clay and pyrite mineralogies associated with FCs and compressions, and regional geological structure. The model presupposes compression-cuticle fossilization under anoxic conditions for late authigenic deposition of sub-micron-sized pyrite on the compressions. Rock joints subsequently provided conduits for oxygen-enriched ground-water circulation to initiate in situ pyritic oxidation that produced sulfuric acid for macerating compressions, with resultant loss of vitrinite, but with preservation of cuticles as FCs. The timing of the process remains undetermined, though it is assumed to be late to post-diagenetic. Although FCs represent a pathway of organic matter transformation (pomd) distinct from other plant-fossilization processes, global applicability of the chemical models remains to be tested. CCs and FCs are inferred endpoints on a spectrum of pomd which complicates assessing origin of in-between transformations (partially macerated cuticles). FCs index highly acidic levels that existed locally in the roof rocks.

    Injecting drug use is commonly reported among gay and bisexual men in Australia. We examined the prevalence and covariates of injecting drug use among men participating in the Sydney Gay Community Periodic Survey between 2004-06 and 2011. In 2004-06, data was collected about which drugs were injected, while in 2011, data was collected about hepatitis C (HCV) and esoteric sexual practices. In 2004-06, 5.6 % of men reported injecting drugs in the previous 6 months; 3.4 % reported methamphetamine injection and 0.4 % heroin injection. In 2011, men who injected drugs were less likely to be employed full-time, and more likely to be HCV-positive, HIV-positive, to have used party drugs for sex, and to have engaged in esoteric sexual practices. The strong associations between injecting drug use, sexual risk practices and blood-borne virus infection suggests the need for combined sexual health and harm reduction services for gay and bisexual men who inject drugs.

  9. A cross-sectional study of pre-travel health-seeking practices among travelers departing Sydney and Bangkok airports

    PubMed Central

    2012-01-01

    Background Pre-travel health assessments aim to promote risk reduction through preventive measures and safe behavior, including ensuring travelers are up-to-date with their immunizations. However, studies assessing pre-travel health-seeking practices from a variety of medical and non-medical sources and vaccine uptake prior to travel to both developing and developed countries within the Asia-Pacific region are scarce. Methods Cross-sectional surveys were conducted between July and December 2007 to assess pre-travel health seeking practices, including advice from health professionals, health information from other sources and vaccine uptake, in a sample of travelers departing Sydney and Bangkok airports. A two-stage cluster sampling technique was used to ensure representativeness of travelers and travel destinations. Pre-travel health seeking practices were assessed using a self-administered questionnaire distributed at the check-in queues of departing flights. Logistic regression models were used to identify significant factors associated with seeking pre-travel health advice from a health professional, reported separately for Australian residents, residents of other Western countries and residents of countries in Asia. Results A total of 843 surveys were included in the final sample (Sydney 729, response rate 56%; Bangkok 114, response rate 60%). Overall, pre-travel health information from any source was sought by 415 (49%) respondents with 298 (35%) seeking pre-travel advice from a health professional, the majority through general practice. Receipt of a pre-travel vaccine was reported by 100 (12%) respondents. Significant factors associated with seeking pre-travel health advice from a health professional differed by region of residence. Asian travelers were less likely to report seeking pre-travel health advice and uptake of pre-travel vaccines than Australian or other Western travelers. Migrant Australians were less likely to report seeking pre-travel health advice than Australian-born travelers. Conclusions This study highlights differences in health-seeking practices including the uptake of pre-travel health advice by region of residence and country of birth. There is a public health need to identify strategies targeting these travel groups. This includes the promotion of affordable and accessible travel clinics in low resource countries as traveler numbers increase and travel health promotion targeting migrant groups in high resource countries. General practitioners should play a central role. Determining the most appropriate strategies for increasing pre-travel health preparation, particularly for vaccine preventable diseases in travelers is the next stage in advancing travel medicine research.

    Background Rapid HIV testing (RHT) is well established in many countries, but it is new in Australia. We assessed the acceptability of RHT and its associations among gay, bisexual and other men who have sex with men (GBM) after implementation of RHT in Sydney sexual health clinics. Methods GBM were invited to complete an acceptability questionnaire before and after provision of the result of finger-prick blood RHT, comparing their experience of RHT with conventional HIV testing (CHT) involving venipuncture. Logistic regression was used to assess associations between patient characteristics and the preference for RHT over CHT next time they tested for HIV. Results Of 1061 GBM who received non-reactive RHT results, 59% found RHT less stressful than CHT and 34% reported no difference, and 61% found RHT more comfortable than CHT and 26% reported no difference. Nearly all men were satisfied with RHT result delivery (99%) and the RHT process overall (99%). Most men (79%) preferred RHT for their next HIV test and this preference was stronger in men who were aged 35-44 years (adjusted odds ratio [AOR] 2.49, p<0.01), reported they would test more often if RHT was available (AOR 1.66, p=0.01), found returning for results annoying (AOR 1.67, p=0.01), and found RHT less stressful (AOR 2.37, p<0.01) and more comfortable (AOR 1.62, p=0.02) than CHT. Men concerned about the reliability of RHT were less than half as likely to prefer RHT for their next HIV test (AOR 0.44, p<0.01). Conclusions Most GBM preferred RHT to CHT next time and this preference was associated with finding RHT more convenient, more comfortable and less stressful than CHT. These findings suggest that in a clinic setting RHT should be considered to improve the patient experience and may potentially increase uptake and frequency of HIV testing. PMID:25898140

    Until now, Carboniferous-altered volcanic ash in North America was known only from the Middle Pennsylvanian (upper Westphalian A to lower Westphalian D) of the Appalachian basin. Now, however, mineralogical analysis of thin claystones (8-24 mm thick) in mineable bituminous coal (Hub and Harbour seams) form the P-boreholes in the Donkin submarine areas of the Sydney coalfield, Nova Scotia, indicates the presence of trace amounts of minerals probably derived from a volcanic ash fall of late Westphalian D age. Water-clear to cloudy quartz splinters and euhedral zircon with sharp crystal faces and edges, and length-to-width ratios up to 6:1 - which are typical of Appalachian altered acidic volcanic ash deposits (tonsteins) - were with a dominantly detrital (fluvial ) mineral suite. Fifty to 90% water-laid silt- to sand-size detrital grains of quartz, tourmaline( ), zircon, white mica, and other minerals are found in the HF residum after the removal of the dominant components: clay minerals, pyrite, and coal particles (spores, secretinite, etc.). The fine size of the volcanic minerals and their low concentration indicate a very distant volcanic ash source, perhaps western Europe, where volcanic activity extended into the Stephanian.

    Introduction HIV diagnoses among gay and bisexual men have increased over the past decade in Australia. HIV point-of-care testing (POCT) was introduced in Australia in 2011 as a strategy to increase HIV testing by making the testing process more convenient. We surveyed gay and bisexual men undergoing POCT to assess barriers to HIV testing and characteristics associated with not having previously tested for HIV (never testing). Methods During 2011 and 2012, gay and bisexual men who were undergoing POCT at four Sydney sexual health clinics self-completed questionnaires assessing testing history and psychological and structural barriers to HIV testing. Bivariate and multivariate logistic regression was used to assess associations between patient characteristics and never testing. Results Of 1093 participants, 981 (89.9%) reported ever testing for HIV and 110 (10.1%) never testing. At least one barrier to testing was reported by 1046 men (95.7%), with only 47 men (4.3%) not reporting any barrier to testing. The most commonly reported barriers to testing were annoyance at having to return for results (30.2%), not having done anything risky (29.6%), stress in waiting for results (28.4%), being afraid of testing positive (27.5%) and having tested recently (23.2%). Never testing was independently associated with being non-gay-identified (adjusted odds ratio [AOR]: 1.9; 95% confidence interval [CI]: 1.1–3.2), being aged less than 25 years (AOR: 2.4; 95% CI: 1.6–3.8), living in a suburb with few gay couples (AOR: 1.9; 95% CI: 1.2–3.0), being afraid of testing HIV-positive (AOR: 1.6; 95% CI: 1.0–2.4), not knowing where to test (AOR: 3.8; 95% CI: 1.3–11.2) and reporting one or no sexual partners in the last six months (AOR: 2.7; 95% CI: 1.2–6.2). Conclusions Barriers to HIV testing were commonly reported among the clinic-based gay and bisexual men in this study. Our findings suggest further health promotion and prevention strategies are needed to address the knowledge, attitudes and behavioural factors associated with never testing. PMID:26318960

    The Sydney rock oyster, Saccostrea glomerata, has been demonstrated as a useful biomonitor of estrogenic compounds following laboratory exposures, yet its utility in the assessment of estrogenic exposure and effects under field conditions requires investigation. To achieve this aim, S. glomerata were deployed in Newcastle, Australia in the effluent receiving marine waters of Burwood Beach WWTP (Burwood Beach "near", <50 m from outfall and Burwood Beach "far", 100-150 m from outfall) and reference locations (Redhead, Fingal Island 1 and Fingal Island 2) at depths of 4, 8 and 12 m for six weeks. Effluent receiving waters of Burwood Beach WWTP were found to be a suitable impact location, demonstrated via measurement of estrogenic compounds and activity throughout the deployment. Estrogenic compounds were detected (average of combined solids and liquid fractions) at average concentrations of: 1.42 ng/L for estrone, 0.69 ng/L for 17? estradiol, 3.83 ng/L for estriol (E3), 0.56 ng/L for 17?-ethynylestradiol, 64.2 ng/L for bisphenol A, 7.51 ng/L for 4-nonylphenol and 5.93 ng/L for 4-tert-octylphenol. Total estrogenic activity was estimated at 4.48 ng/L EEQ via the Yeast Estrogen Screen (YES(®)) assay (average of combined solid and liquid fractions). Female vitellogenin gene expression was highest at Burwood Beach locations, yet no significant differences were detected among locations for either sex. Vitellogenin protein was significantly higher (p<0.05) in S. glomerata at Burwood Beach Near compared to reference locations for the 4 and 12 m depths. Increased proportions of females were found at Burwood Beach Near, at 4m depth (p<0.05). Both Burwood Beach locations had higher proportions of mature female gonadal development stages compared to reference locations (p<0.05). Oocyte area was highest at both Burwood Beach locations, but no significant differences were detected among locations. Findings provided further evidence that female S. glomerata may be a suitable candidate species for assessment of effects of estrogenic compounds in Australian waters. PMID:22673404

Blood samples were taken from 367 women at their first antenatal visit between 7 and 11 weeks gestation for measurement of thyroid stimulating hormone (TSH) and free thyroxine (FT4) levels and spot urine samples for urinary iodine excretion were taken at the same time as blood collection. Results. The median urinary iodine concentration (UIC) for all women was 81??g/l (interquartile range 41–169??g/l). 71.9% of the women exhibited a UIC of <150??g/l. 26% of the women had a UIC <50??g/l, and 12% had a UIC <20??g/l. The only detectable influences on UIC were daily milk intake and pregnancy supplements. There was no statistically significant association between UIC and thyroid function and no evidence for an effect of iodine intake on thyroid function. Conclusions. There is a high prevalence of mild to moderate iodine deficiency in women in Western Sydney but no evidence for a significant adverse effect on thyroid function. The 6.5% prevalence of subclinical hypothyroidism is unlikely to be due to iodine deficiency. PMID:23209946

    Agglutinated foraminifera and arcellaceans (the camoebians) were examined from Carboniferous (Late Westphalian-Stephanian) cyclothems in the Sydney Basin of Nova Scotia. Their presence confirms that the laterally extensive coal seams, limestones, mudstones and carbonaceous shales were deposited in a paralic setting. Four distinctive assemblages are documented from the coal-bearing strata, and these may be used as accurate paleo sea-level indicators on the basis of the modern distribution of similar assemblages. Mixed assemblages dominated by Ammobaculites characterize siltstones overlying the coal seams, an association typical of mineralic substrates within modern estuarine environments. Assemblages dominated by small, finely agglutinated specimens of Ammotium and Ammobaculites occur in organic rich strata between coal seam splits. Similar assemblages are found in modern salt marshes and upper estuarine settings. Trochammina dominated assemblages occur in mudstones underlying the coal seams. Such assemblages are typical of higher elevations in modern brackish and saline marshes. Monotypic assemblages of the arcellacean Difflugia are also found in the seat earths below coal seams. Similar associations occur today in mineralic substrates below modern freshwater floating marshes. The presence of a Trochammina assemblage has aided recognition of a maximum flooding (transgression) surface below the base of an incised paleovalley, interpreted as a type 1 sequence boundary, in the Bonar cyclothem of the Sydney Basin. The valley incision is attributed to glacioeustatic sea-level lowering. The upper 10m of the 25m thick valley fill contains assemblages of Difflugia, which are succeeded by Trochammina assemblages within the seat earth beneath the coal at the top of the cyclothem.

    The aim in this paper is to assess the hydrological and economic impacts of deploying water in the political jurisdictions of the peri-urban South Creek catchment of Western Sydney. This catchment has been identified as the region in which the city of Sydney will grow into in the future, with a plan to move an extra one million people into the catchment in the next 25-30 years. In conjunction with this expansion, a plan exists to augment the existing water supply by treating waste water effluent, harvesting stormwater and improving irrigation efficiency, along with a strategy for saving water on farms. Water in this catchment is operated by and in the interests of society, where decisions on its allocation have a political perspective to them. However, the growth within this catchment and the water augmentation strategies are not split evenly amongst the political entities within this catchment, namely the Local Government Authorities. An integrated hydro-economic model segregated according to the political entities in the catchment is used in this study to address a range of water saving scenarios raised by stakeholders. The trade-offs inherent in all water allocation decisions on a regional basis are made transparent in this model and its political ramifications, defined as the impacts on different political regions, are identified. In analysing the measures designed to save water across the catchment, none resulted in a positive Net Present Value. Even just expanding the system to accommodate one million extra people resulted in significant economic losses. In addition, the impact of each measure in each political region was markedly different. The purpose of this study is to provide stakeholders in individual local government regions with evidence of the costs and impacts of rational decisions to change the management of water resources in South Creek catchment.

    An understanding of ecological processes hinges upon an understanding of the spatial structuring of their key biotic components. Interstitial invertebrates are a ubiquitous and ecologically important component of sandy beach ecosystems. As many sandy beach taxa have limited dispersal, it may be expected that their populations exhibit a high degree of spatial structuring, yet the spatial scales across which they display baseline variability remain largely unknown. To assess (1) whether interstitial invertebrates display patchiness on embayed sandy beaches, (2) whether the size of patches they form is consistent across three geographically proximal beaches, (3) the key environmental correlates of this variation and (4) its taxonomic dependence, samples were collected at regular (0.5 m) intervals along 15 m long geomorphically similar stretches of three proximal intermediate beaches and analyses of spatial autocorrelation were conducted. On each of the three beaches, interstitial invertebrate communities formed patches of 2-4.5 m in diameter. Spatial structuring of invertebrate communities was driven by harpacticoid copepods and gastrotrichs, and corresponded to spatial structuring of sediments. Sediments, however, explained only 33% of spatial variation in faunal communities, indicating the importance of other abiotic and/or biotic factors. Our study highlights that even on seemingly homogeneous sandy beaches, faunal communities may display considerable small-scale spatial structuring. Examination of spatial structure may lead to a greater understanding of the ecological processes in this system.

    Objectives To determine whether humour therapy reduces depression (primary outcome), agitation and behavioural disturbances and improves social engagement and quality-of-life in nursing home residents. Design The Sydney Multisite Intervention of LaughterBosses and ElderClowns study was a single-blind cluster randomised controlled trial of humour therapy. Setting 35 Sydney nursing homes. Participants All eligible residents within geographically defined areas within each nursing home were invited to participate. Intervention Professional ‘ElderClowns’ provided 9–12?weekly humour therapy sessions, augmented by resident engagement by trained staff ‘LaughterBosses’. Controls received usual care. Measurements Depression scores on the Cornell Scale for Depression in Dementia, agitation scores on the Cohen-Mansfield Agitation Inventory, behavioural disturbance scores on the Neuropsychiatric Inventory, social engagement scores on the withdrawal subscale of Multidimensional Observation Scale for Elderly Subjects, and self-rated and proxy-rated quality-of-life scores on a health-related quality-of-life tool for dementia, the DEMQOL. All outcomes were measured at the participant level by researchers blind to group assignment. Randomisation Sites were stratified by size and level of care then assigned to group using a random number generator. Results Seventeen nursing homes (189 residents) received the intervention and 18 homes (209 residents) received usual care. Groups did not differ significantly over time on the primary outcome of depression, or on behavioural disturbances other than agitation, social engagement and quality of life. The secondary outcome of agitation was significantly reduced in the intervention group compared with controls over 26?weeks (time by group interaction adjusted for covariates: p=0.011). The mean difference in change from baseline to 26?weeks in Blom-transformed agitation scores after adjustment for covariates was 0.17 (95% CI 0.004 to 0.34, p=0.045). Conclusions Humour therapy did not significantly reduce depression but significantly reduced agitation. Trial registration Australian New Zealand Clinical Trials Registry -ACTRN12611000462987.

    Sphenopterid specimens from the Late Pennsylvanian of Sydney Coalfield, Canada, are investigated by FTIR and py-GC-MS techniques as part of an on-going research project into the biochemistry and chemotaxonomy of Pennsylvanian-age pteridophylls. Included in the investigation are samples of the true-fern species Oligocarpia brongniartii and Zeilleria delicatula that are preserved as naturally macerated cuticles (NMC), and the seed-fern Eusphenopteris neuropteroides that is also preserved as a compression/impression. FTIR spectra of NMC seed-fern E. neuropteroides, and fern sphenopterid O. brongniartii are very similar, except that the latter does not have aromatic bands in the 700-900 cm-1 out-of-plane region, py-GC-MS show more aromatic compounds for the seed fern than for the two true-fern sphenopterids. Another difference between seed-fern and true-fern sphenopterids is a lower ratio of CH2 to CH3 in chemically treated specimens (CTC) for the seed fern. These observations suggest slightly higher aromaticity for the seed ferns, perhaps related to some chemotaxonomic differences. Comparison of FTIR and py-GC-MS characteristics of sphenopterids and other plant groups shows that these two techniques have potential to identifying chemotaxonomic signals from Carboniferous pteridophylls in general, although more data are needed to confirm this. ?? 2002 Elsevier Science B.V.

    This study evaluated lead, arsenic, and polycyclic aromatic hydrocarbon (PAH) contamination in the residential communities adjacent to the Sydney, Nova Scotia, tar ponds, the area considered Canada's worst contaminated site. The tar pond remediation policy has been limited to the site and some residential properties. We compared background concentrations in 91 soil samples taken 5-20 km from the coke oven site with those in soil samples from the three communities surrounding the tar ponds: Whitney Pier, Ashby, and North End. These surrounding communities were statistically different from background regarding arsenic, lead, and PAHs. Twenty percent of the background soil samples and 95% of the tar pond soil samples were above the Canadian health-risk-based soil guidelines for arsenic (12 ppm), and 5% of the background samples and 80% of the tar pond soil samples were above the Canadian guidelines for lead (140 ppm). Regarding dust lead and arsenic loading, the results provide no evidence that Whitney Pier is significantly different than Ashby and North End. Children in these communities are predicted to have a 1-15% chance of blood lead > 10 microg/dL. The results suggest that lead and arsenic found in the homes originate outside. The lead content of paint in the homes was not evaluated, but consideration of painted wood at the doorway did not confound the results of the study. The results indicate that the residential environment has been adversely affected by PAHs, lead, and arsenic and should be considered for remediation. PMID:14698928

  15. Incorporation of Radon-222 as a parameter in ME-2 to improve apportionment of PM2.5 sources in the Sydney region

    In recent years source apportionment of observed PM2.5 has been improved by incorporating meteorological information as additional factors in receptor modelling studies using ME-2. In this study we replace one of these meteorological factors, namely, parameterisation by wind speed, with a parameterisation based on hourly observations of the naturally occurring terrestrial gas Radon-222 (radon), and compare results of the two parameterisations over five years at an inland site in the Greater Sydney Region. The efficacy of the wind speed and radon parameterisation techniques is assessed by comparing regressions between the daily contributions from identified elemental fingerprints estimated from the wind speed and radon multi-linear models against those obtained from the corresponding bi-linear model (while the two models are solved simultaneously). The radon parameterisation yielded improved regressions for all source fingerprints, most notably Smoke and Autos (r2 = 0.67 and 0.65, respectively, compared to 0.57 and 0.47 when the wind speed parameterisation was used). Both parameterisation schemes were equally effective in attributing PM2.5 to wind sectors known to contain sources characterised by the observed fingerprints. Our findings demonstrate that incorporating radon as a parameter in ME-2 can lead to an improved PM2.5 source apportionment than that obtained using meteorological parameters alone, particularly for inland sites with distributed sources.

  17. The Westphalian D fossil lepidodendrid forest at Table Head, Sydney Basin, Nova Scotia: Sedimentology, paleoecology and floral response to changing edaphic conditions

    Strata of Westphalian D age on the western coast of the Sydney Basin expose a fossil forest of approximately 30 lepidodendrid trees within one of several clastic splits of the Harbour Seam. A mutidisciplinary approach was employed to interpret the origins of the coal bed, the depositional history of the site and the response of the fossil forest to changing edaphic conditions. The megaspore and miospore records indicate that the mire vegetation was dominated by arboreous lycopsids, especially Paralycopodites, with subdominant tree ferns. Petrographic, palynological and geochemical evidence suggest that the Harbour coal bed at Table Head originated as a rheotrophic (cf. planar) mire (eutric histosol). The mire forest is interpreted to have been engulfed by prograding distributary-channel sediments; sparse protist assemblages are suggestive of a freshwater delta-plain lake environment occasionally in contact with brackish waters. Lepidodendrids persisted as site colonizers of clastic substrates even after burial of the rheotrophic peatland and influenced the morphology of deposited sediment, but apparently were unable to colonize distributary channels. Equivocal taxonomic data (compression fossils) show the fossil forest to have been composed of both monocarpic (Lepidodendron) and polycarpic (Diaphorodendron, Paralycopodites, ?Sigillaria) lycopsids, genera recorded in the palynology of the uppermost ply of the underlying coal bed. Comparatively rare within the clastic beds of the fossil forest, however, is the stem compression of Paralycopodites, whose dispersed megapores and miospores dominate the underlying coal bed. Tree diameter data recorded equivalent to breast height indicate a forest of mixed age. These data would appear to suggest that some lepidodendrids employing a polycarpic reproductive strategy were better able to cross the ecological barrier imposed between peat and clastic substrates. Foliar compressions indicate that an understory or stand of Psaronius type tree ferns co-existed with the lepidodendrids on clastic substrates, which developed as incipient gleysol soils. The entombment of the forest can be ascribed to its distributary coastal setting, local subsidence and a seasonal climate that fostered wildfire and increased sedimentation.

    Introduction An aging population brings increasing burdens and costs to individuals and society arising from late-life cognitive decline, the causes of which are unclear. We aimed to identify factors predicting late-life cognitive decline. Methods Participants were 889 community-dwelling 70–90-year-olds from the Sydney Memory and Ageing Study with comprehensive neuropsychological assessments at baseline and a 2-year follow-up and initially without dementia. Cognitive decline was considered as incident mild cognitive impairment (MCI) or dementia, as well as decreases in attention/processing speed, executive function, memory, and global cognition. Associations with baseline demographic, lifestyle, health and medical factors were determined. Results All cognitive measures showed decline and 14% of participants developed incident MCI or dementia. Across all participants, risk factors for decline included older age and poorer smelling ability most prominently, but also more education, history of depression, being male, higher homocysteine, coronary artery disease, arthritis, low health status, and stroke. Protective factors included marriage, kidney disease, and antidepressant use. For some of these factors the association varied with age or differed between men and women. Additional risk and protective factors that were strictly age- and/or sex-dependent were also identified. We found salient population attributable risks (8.7–49.5%) for older age, being male or unmarried, poor smelling ability, coronary artery disease, arthritis, stroke, and high homocysteine. Discussion Preventing or treating conditions typically associated with aging might reduce population-wide late-life cognitive decline. Interventions tailored to particular age and sex groups may offer further benefits. PMID:23799051

A district heating system at Portland, in the Otway Basin of western Victoria, has provided uninterrupted service for 12 Sears without significant problems, is servicing a building area of 18 990 m{sup 2}, and has prospects of expansion to manufacturing uses. A geothermal well has provided hot water for paper manufacture at Traralgon, in the Gippsland Basin of eastern Victoria. Power production from hot water aquifers was tested at Mulka in South Australia, and is undergoing a four-year production trial at Birdsville in Queensland. An important Hot Dry Rock resource has been confirmed in the Cooper Basin. It has been proposed to build an HDR experimental facility to test power production from deep conductive resources in the Sydney Basin near Muswellbrook.

    This article presents evidence demonstrating that the historical use of leaded gasoline and lead (Pb) in exterior paints in Australia has contaminated urban soils in the older inner suburbs of large cities such as Sydney and Melbourne. While significant attention has been focused on Pb poisoning in mining and smelting towns in Australia, relatively little research has focused on exposure to Pb originating from inner-city soil dust and its potential for childhood Pb exposures. Due to a lack of systematic blood lead (PbB) screening and geochemical soil Pb mapping in the inner cities of Australia, the risks from environmental Pb exposure remain unconstrained within urban population centres.

    Australia's largest city of Sydney was clouded with smoke when more than 70 wildfires raged across the state of New South Wales. These images were captured on the morning of December 30, 2001, by the Multi-angle Imaging SpectroRadiometer (MISR) instrument aboard NASA's Terra spacecraft. The left-hand image is from the instrument's 26-degree forward-viewing camera, and the right-hand image is from the 60-degree forward-viewing camera. The vast extent of smoke from numerous fires is visible, particularly in the more oblique view. Sydney is located just above image center.

    Dubbed the 'black Christmas' fires, the blazes destroyed more than 150 homes and blackened over 5000 square kilometers (about 1.24 million acres) of farmland and wilderness between December 23, 2001 and January 3, 2002. Many of the fires are believed to have been caused by arsonists, with only one fire linked to natural causes. The fires were aggravated by gusty winds and hot dry weather conditions.

  11. Medicine in colonial Australia, 1788-1900.

    PubMed

    Lewis, Milton J

    2014-07-01

    For the first five decades of European settlement in Australia, medical care for convicts and free settlers was provided by the Colonial Medical Service. After about 1850, as population and wealth grew markedly, there was significant professional development based on private practice. Except in Victoria, medical societies and journals did not become solidly established until late in the 19th century. The advent of local British Medical Association branches was an important factor in this consolidation. In the first few years of the colony, mortality was very high, but the common childhood infections were absent until the 1830s. From the 1880s, there was a sustained decline in mortality from communicable diseases, and therefore in aggregate mortality, while maternal mortality remained high. Australian practitioners quickly took up advances in practice from overseas, such as antisepsis and diphtheria antitoxin. They shared in the international growth in the status of medicine, which was conferred by the achievements of bacteriology in particular. From 1813, students were apprenticed in Sydney and Hobart and then travelled to Britain to obtain corporate qualifications. Medical schools were ultimately opened in the new universities in Melbourne (in 1862), Sydney (1883) and Adelaide (1885). The first female student was admitted to medicine in Sydney in 1885. Medical politics were intense. The outlawing of practice by unorthodox practitioners proved to be an unattainable goal. In the latter half of the 19th century, doctors saw chemists as unfair competitors for patients. The main medicopolitical struggle was with the mutual-aid friendly societies, which funded basic medical care for a significant proportion of the population until well into the 20th century. The organised profession set out to overcome the power of the lay-controlled societies in imposing an unacceptable contract system on doctors, even if, historically, the guaranteed income was a sine qua non of practice in poorer areas.

    Background This paper examines the differences in demographics, drug use patterns and self reported risk behaviours between regular injecting drug users (IDU) who report engaging in sex work for money or drugs and regular injecting drug users who do not. Methods Cross sectional data collected from regular IDU interviewed as part of the New South Wales (NSW) Illicit Drug Reporting System (IDRS) in 2003 were analysed. Results IDU who reported engaging in sex work were more likely to be female, and identify as being of Aboriginal and/or Torres Strait Islander descent. They initiated injecting drug use at a significantly younger age and were more likely to report injection related problems than IDU who had not engaged in sex work. There were no differences in the drug classes used, but findings suggested that the sex workers tended to be more frequent users of crystalline methamphetamine (ice) and benzodiazepines. Conclusion The similarities between these groups were more striking than the differences. Further research, examining a larger sample is needed to clarify whether injecting drug users who are sex workers have heavier use patterns. PMID:15935103

  18. Emergency department visits, ambulance calls, and mortality associated with an exceptional heat wave in Sydney, Australia, 2011: a time-series analysis

    PubMed Central

    2012-01-01

    Background From January 30-February 6, 2011, New South Wales was affected by an exceptional heat wave, which broke numerous records. Near real-time Emergency Department (ED) and ambulance surveillance allowed rapid detection of an increase in the number of heat-related ED visits and ambulance calls during this period. The purpose of this study was to quantify the excess heat-related and all-cause ED visits and ambulance calls, and excess all-cause mortality, associated with the heat wave. Methods ED and ambulance data were obtained from surveillance and administrative databases, while mortality data were obtained from the state death registry. The observed counts were compared with the average counts from the same period from 2006/07 through 2009/10, and a Poisson regression model was constructed to calculate the number of excess ED visits, ambulance and deaths after adjusting for calendar and lag effects. Results During the heat wave there were 104 and 236 ED visits for heat effects and dehydration respectively, and 116 ambulance calls for heat exposure. From the regression model, all-cause ED visits increased by 2% (95% CI 1.01-1.03), all-cause ambulance calls increased by 14% (95% CI 1.11-1.16), and all-cause mortality increased by 13% (95% CI 1.06-1.22). Those aged 75 years and older had the highest excess rates of all outcomes. Conclusions The 2011 heat wave resulted in an increase in the number of ED visits and ambulance calls, especially in older persons, as well as an increase in all-cause mortality. Rapid surveillance systems provide markers of heat wave impacts that have fatal outcomes. PMID:22273155

    Abstract Hoplatessara luxuriosa (Silvestri, 1895) is partly redescribed and illustrated. Its native range is shown to be in the cool-climate uplands of New South Wales, Australia. H. luxuriosa was originally labelled as collected by L.M. D’Albertis at Sorong in New Guinea. D’Albertis collected on Sorong Island in 1872 and spent the following year in Sydney, New South Wales, before returning to Europe with his New Guinea specimens. It is possible that D’Albertis himself collected H. luxuriosa in 1873, and that the mislabelling occurred later. PMID:24146549

    In August 2007 Australia experienced its first outbreak of equine influenza. The disease occurred first in a quarantine station for imported horses near Sydney and subsequently escaped into the general horse population. After an extensive campaign the disease was eradicated and Australia is again recognised as free of this disease. Equine influenza was then, and is now, recognised to be the major disease risk associated with live horse imports into Australia and measures designed to mitigate this risk formed the basis of the quarantine protocols then in place. Subsequent investigations into the cause of the outbreak identified failures in compliance with these quarantine requirements as a contributing factor. It is also likely that the immunity of horses vaccinated as part of the import protocol was less than optimal, and that this had a significant role to play in the escape of the disease from quarantine.

    The smallest continent and one of the largest countries, Australia is a country of diverse geographical conditions and differing cultures of people unified by one predominant language and political system. Mountains, desert and rivers are some of the varying landscape features of Australia, although the climate and condition for most of the country is tropical. Original Australians, a hunting-gathering people called Aborigines, came to Australia over 38,000 years ago. Today the Aborigines compose about 1% of the population and live in traditional tribal areas as well as cities. The 1st European settlement came in 1788 from Great Britain. After World War II, the population doubled. Although the population is primarily composed of British and Irish immigrants, immigrants from other European countries such as Italy and Greece as well as refugees from Indochina, Vietnam, Cambodia and Laos are a significant factor to the growing Australian population. Australian and Aboriginal culture has took hold and took notice in the areas of opera, art, literature and film. The Australian Commonwealth is based on a constitution similar to that of the United States government. The National Parliament is bicameral with both the Senate and the House of Representatives having a select number of elected officials from each state and territory. The Australian economy is predominantly reliant on the sale of mineral and agricultural exports. History, economic changes, defense, international relations and notes to the traveler are also discussed in this overview of Australia. PMID:12177993

    Despite the wide acceptance of Failure-to-Rescue (FTR) as a patient safety indicator (defined as the deaths among surgical patients with treatable complications), no study has explored the geographic variation of FTR in a large health jurisdiction. Our study aimed to explore the spatiotemporal variations of FTR rates across New South Wales (NSW), Australia. We conducted a population-based study using all admitted surgical patients in public acute hospitals during 2002–2009 in NSW, Australia. We developed a spatiotemporal Poisson model using Integrated Nested Laplace Approximation (INLA) methods in a Bayesian framework to obtain area-specific adjusted relative risk. Local Government Area (LGA) was chosen as the areal unit. LGA-aggregated covariates included age, gender, socio-economic and remoteness index scores, distance between patient residential postcode and the treating hospital, and a quadratic time trend. We studied 4,285,494 elective surgical admissions in 82 acute public hospitals over eight years in NSW. Around 14% of patients who developed at least one of the six FTR-related complications (58,590) died during hospitalization. Of 153 LGAs, patients who lived in 31 LGAs, accommodating 48% of NSW patients at risk, were exposed to an excessive adjusted FTR risk (10% to 50%) compared to the state-average. They were mostly located in state's centre and western Sydney. Thirty LGAs with a lower adjusted FTR risk (10% to 30%), accommodating 8% of patients at risk, were mostly found in the southern parts of NSW and Sydney east and south. There were significant spatiotemporal variations of FTR rates across NSW over an eight-year span. Areas identified with significantly high and low FTR risks provide potential opportunities for policy-makers, clinicians and researchers to learn from the success or failure of adopting the best care for surgical patients and build a self-learning organisation and health system.

    Objective On 7 April 2012, a recently returned traveller from Thailand to Australia was confirmed to have measles. An outbreak of measles subsequently occurred in the state of New South Wales, prompting a sustained and coordinated response by public health authorities. The last confirmed case presented on 29 November 2012. This report describes the outbreak and its characteristics. Methods Cases were investigated following Australian protocols, including case interviews and assessment of contacts for post-exposure prophylaxis. Results Of the 168 cases identified, most occurred in south-western and western Sydney (92.9%, n = 156). Notable features of this outbreak were the disproportionately high number of cases in the 10–19-year-old age group (29.2%, n = 49), the overrepresentation among people of Pacific Islander descent (21.4%, n = 36) and acquisition in health-care facilities (21.4%, n = 36). There were no reported cases of encephalitis and no deaths. Discussion: This was the largest outbreak of measles in Australia since 1997. Its occurrence highlights the need to maintain vigilant surveillance systems for early detection and containment of measles cases and to maintain high population immunity to measles through routine childhood immunization. Vaccination campaigns targeting susceptible groups may also be necessary to sustain Australia’s measles elimination status. PMID:25635228

Minibrachium, n. subg. is characterised by such paedomorphic features as lack of peristomial cirri and branchiae, possession of only two pairs of modified parapodia with spiny recurved hooks and very early onset of subacicular hooks. Three new species are described, of which at least R. (Minibrachium) nutrix n. sp., the type species (from Lizard Island, Great Barrier Reef), is a fully grown adult, brooding several 16- to 20-chaetiger juveniles in the parental tubes. Rhamphobrachium (M.) talboti n. sp. (from off Sydney) and R. (M.) fractum n. sp. (from Bass Strait), although twice as large as the type species, have only partially developed frontal lips, indicating either incomplete growth or presenting an additional paedomorphic character. We discuss the position of the new subgenus in the Rhamphobrachium complex and present a key to the subgenera of Rhamphobrachium and species of R. (Minibrachium). PMID:26624081

    The disposal of untreated urban and industrial wastewater has a deleterious effect on both the water and sediment quality of Oyster Bay located in south Sydney, Australia. The present investigation was undertaken to evaluate the potential pollution of marine sediments in Oyster Bay. The results of metals were compared with adverse biological effect values effect range low (ERL) and effect range median (ERM). Spatial distribution of trace metals was estimated by applying geographic information system. The results indicated that the sediments were polluted with Cu, Zn, As and Pb, which exceeded ERL levels. However, these metals were still below ERM values, and other metals Cr and Ni were below ERL. Moreover, the highest concentrations of metals were around discharge points and in the inner bay. Further, trace metals could be attributed to human activities within the bay as they declined in concentrations with increasing sediment depth. PMID:25432296

    In our survey of 500 mothers with children 0-5 years involving telephone interviews (n = 450) and focus groups (n = 50), we showed that 87% of mothers telephone surveyed used a pram for incidental activities, whilst 47% used the pram specifically for exercise. Factors preventing mothers exercising more included poor weather, lack of time, and poor quality paths. Ninety-two percent of mothers believed that pram walking would increase mental well-being, and 87% felt that it would help to reduce postnatal depression (PND). However, feedback from focus groups expressed less confidence in the program's ability to potentially benefit mothers with PND. Programs will have to be marketed carefully to avoid the stigma associated with PND and successfully target mothers at risk. PMID:12487703

    Leishmaniasis is a vector borne disease caused by protozoa of the genus Leishmania. Human leishmaniasis is not endemic in Australia though imported cases are regularly encountered. This study aimed to provide an update on the molecular epidemiology of imported leishmaniasis in Australia. Of a total of 206 biopsies and bone marrow specimens submitted to St Vincent’s Hospital Sydney for leishmaniasis diagnosis by PCR, 55 were found to be positive for Leishmania DNA. All PCR products were subjected to restriction fragment length polymorphism analysis for identification of the causative species. Five Leishmania species/species complexes were identified with Leishmania tropica being the most common (30/55). Travel or prior residence in a Leishmania endemic region was the most common route of acquisition with ~47% of patients having lived in or travelled to Afghanistan. Cutaneous leishmaniasis was the most common manifestation (94%) with only 3 cases of visceral leishmaniasis and no cases of mucocutaneous leishmaniasis encountered. This report indicates that imported leishmaniasis is becoming increasingly common in Australia due to an increase in global travel and immigration. As such, Australian clinicians must be made aware of this trend and consider leishmaniasis in patients with suspicious symptoms and a history of travel in endemic areas. This study also discusses the recent identification of a unique Leishmania species found in native kangaroos and a potential vector host which could create the opportunity for the establishment of a local transmission cycle within humans.

    Study of the Oweniidae specimens (Annelida; Polychaeta) from Lizard Island (Great Barrier Reef, Australia) stored at the Australian Museum, Sydney and newly collected in August 2013 revealed the presence of three species, namely Galathowenia quelis Capa et al., 2012 and two new species belonging to the genus Owenia Delle Chiaje, 1844. Owenia dichotoma n. sp. is characterised by a very short branchial crown of about 1/3 of thoracic length which bears short, dichotomously-branched tentacles provided with the major division close to the base of the crown. Owenia picta n. sp. is characterised by a long branchial crown of about 4/5 of thoracic length provided with no major divisions, ventral pigmentation on thorax and the presence of deep ventro-lateral groove on the first thoracic chaetiger. A key of Owenia species hitherto described or reported in South East Asia and Australasia regions is provided based on characters of the branchial crown. PMID:26624080

  1. The decay of wood in landfills in contrasting climates in Australia.

    Wood products in landfill are commonly assumed to decay within several decades, returning the carbon contained therein to the atmosphere, with about half the carbon released as methane. However, the rate and extent of decay is not well known, as very few studies have examined the decay of wood products in landfills. This study reports on the findings from landfill excavations conducted in the Australian cities of Sydney and Cairns located in temperate and tropical environments, respectively. The objective of this study was to determine whether burial of the wood in warmer, more tropical conditions in Cairns would result in greater levels of decay than occurs in the temperate environment of Sydney. Wood samples recovered after 16-44years in landfill were examined through physical, chemical and microscopic analyses, and compared with control samples to determine the carbon loss. There was typically little or no decay in the wood samples analysed from the landfill in Sydney. Although there was significant decay in rainforest wood species excavated from Cairns, decay levels for wood types that were common to both Cairns and Sydney landfills were similar. The current Intergovernmental Panel on Climate Change (IPCC, 2006) default decay factor for organic materials in landfills is 50%. In contrast, the carbon loss determined for Pinus radiata recovered from Sydney and Cairns landfills was 7.9% and 4.4%, respectively, and 0% for Agathis sp. This suggests that climate did not influence decay, and that the more extensive levels of decay observed for some wood samples from Cairns indicates that those wood types were more susceptible to biodegradation. Microscopic analyses revealed that most decay patterns observed in samples analysed from Sydney were consistent with aerobic fungal decay. Only a minor portion of the microbial decay was due to erosion bacteria active in anaerobic/near anaerobic environments. The findings of this study strongly suggest that models that adopt current accepted default factors for the decay of wood in landfills greatly overestimate methane emissions. PMID:25863766

    Viruses of the genus Megalocytivirus have not been detected in wild populations of fish in Australia but circulate in imported ornamental fish. In 2012, detection of a megalocytivirus in healthy platys Xiphophorus maculatus was reported from a farm in Australia during surveillance testing as part of a research project undertaken at the University of Sydney. Confirmatory testing of the original samples at the AAHL Fish Diseases Laboratory verified the presence of an infectious spleen and kidney necrosis virus (ISKNV)-like virus. Additional sampling at the positive farm confirmed the persistence of the virus in the platys, with 39 of 265 (14.7%) samples testing positive. Comparison of 3 separate gene regions of the virus with those of ISKNV confirmed the detection of a virus indistinguishable from ISKNV. Subsequently, ISKNV was also detected in a range of imported ornamental fish from several countries between 2013 and 2014, by screening with real-time PCR and confirmation by conventional PCR and sequence analysis. Accordingly, the current importation of live ornamental fish acts as a potential perpetual source for the establishment of ISKNV viruses within Australia. The testing of the farmed and imported ornamental fish verified the utility of the probe-based real-time PCR assay for screening of ornamental fish for Megalocytivirus. PMID:26480913

  3. Australia's role in HIV prevention in the developing world.

    A scientist with the National Centre in HIV Epidemiology and Clinical Research at the University of New South Wales in Sydney, Australia, addresses the fact that Australians working in the area of HIV infection have been very successful in prevention, treatment, and care. In the early 1980s, a bipartisan political decision was made to foster an effective partnership between HIV-infected communities, health care providers, and governments. HIV-infected communities included sex workers, prisoners, Aboriginal people, and high profile gay community activists. These three different groups succeeded in forming such a partnership, as reflected in the fact that the annual number of new HIV cases is down to 500 from a peak of 3000 in 1984. A key method used to contain HIV infection was needle-and-syringe exchange programs and continuing access to needles to prevent HIV transmission in the injecting drug community. Even though Australia has all this experience and success, it had a backseat role in ushering in the UNAIDS program because Australia did not contribute a significant share of the agency's relatively small budget (US$100 million/year). If Australia were to give just 10%, it would acquire a front row seat along with the Netherlands, Sweden, Belgium, France, and the UK. These nations have the greatest say as to where UNAIDS funds go. The Australian international aid organization has recently received an increase in funds, $110 million for 4 years to spend on four areas, one of which is HIV/AIDS. Australia has just allocated $25 million for a 5-year program for HIV/STD (sexually transmitted disease) prevention in Indonesia. This money would have been able to buy Australia a leading role in UNAIDS. Australians need to reassess their priorities. Australians can help their neighbors in the Asia-Pacific region move away from their denial of HIV to HIV prevention and care. They can conduct clinical trials of shorter and more user-friendly regimens of antiviral drugs that may lead to reduced perinatal transmission and research on microbicides. They can prevent tuberculosis and introduce manageable methods of securing safe blood supplies and mass screening. PMID:8616207

    Between November 2010 and January 2011, triploid Crassostrea gigas (Pacific oysters) cultivated in the Georges River, New South Wales, experienced >95% mortality. Mortalities also occurred in wild diploid C. gigas in the Georges River and shortly thereafter in the adjacent Parramatta River estuary upstream from Sydney Harbour. Neighbouring Saccostrea glomerata (Sydney rock oysters) did not experience mortalities in either estuary. Surviving oysters were collected to investigate the cause of mortalities. Histologically all oysters displayed significant pathology, and molecular testing revealed a high prevalence of ostreid herpesvirus-1 (OsHV-1). Quantitative PCR indicated that many C. gigas were carrying a high viral load at the time of sampling, while the load in S. glomerata was significantly lower (p < 0.001). Subsequent in situ hybridisation experiments confirmed the presence of a herpesvirus in C. gigas but not S. glomerata tissues, suggesting that S. glomerata is not susceptible to infection with OsHV-1. Naïve sentinel triploid C. gigas placed in the Georges River estuary in January 2011 quickly became infected and experienced nearly 100% mortality within 2 wk of exposure, indicating the persistence of the virus in the environment. Phylogenetic analysis of sequences derived from the C2/C6 region of the virus revealed that the Australian strain of OsHV-1 belongs to the microvariant (µ-var) cluster, which has been associated with severe mortalities in C. gigas in other countries since 2008. Environmental data revealed that the Woolooware Bay outbreaks occurred during a time of considerable environmental disturbance, with increased water temperatures, heavy rainfall, a toxic phytoplankton bloom and the presence of a pathogenic Vibrio sp. all potentially contributing to oyster stress. This is the first confirmed report of OsHV-1 µ-var related C. gigas mortalities in Australia. PMID:23872855

    Puccinia psidii sensu lato (s.l.) is an invasive rust fungus threatening a wide range of plant species in the family Myrtaceae. Originating from Central and South America, it has invaded mainland USA and Hawai'i, parts of Asia and Australia. We used CLIMEX to develop a semi-mechanistic global climatic niche model based on new data on the distribution and biology of P. psidii s.l. The model was validated using independent distribution data from recently invaded areas in Australia, China and Japan. We combined this model with distribution data of its potential Myrtaceae host plant species present in Australia to identify areas and ecosystems most at risk. Myrtaceaeous species richness, threatened Myrtaceae and eucalypt plantations within the climatically suitable envelope for P. psidii s.l in Australia were mapped. Globally the model identifies climatically suitable areas for P. psidii s.l. throughout the wet tropics and sub-tropics where moist conditions with moderate temperatures prevail, and also into some cool regions with a mild Mediterranean climate. In Australia, the map of species richness of Myrtaceae within the P. psidii s.l. climatic envelope shows areas where epidemics are hypothetically more likely to be frequent and severe. These hotspots for epidemics are along the eastern coast of New South Wales, including the Sydney Basin, in the Brisbane and Cairns areas in Queensland, and in the coastal region from the south of Bunbury to Esperance in Western Australia. This new climatic niche model for P. psidii s.l. indicates a higher degree of cold tolerance; and hence a potential range that extends into higher altitudes and latitudes than has been indicated previously. The methods demonstrated here provide some insight into the impacts an invasive species might have within its climatically suited range, and can help inform biosecurity policies regarding the management of its spread and protection of valued threatened assets.

    In this manuscript we describe the major components of the Platypus time-of-flight neutron reflectometer at the 20 MW OPAL reactor in Sydney, Australia. Platypus is a multipurpose spectrometer for the characterisation of solid thin films, materials adsorbed at the solid-liquid interface and free-liquid surfaces. It also has the capacity to study magnetic thin films using spin-polarised neutrons. Platypus utilises a white neutron beam ( ?=2-20 Å) that is pulsed using boron-coated disc chopper pairs; thus providing the capacity to tailor the wavelength resolution of the pulses to suit the system under investigation. Supermirror optical components are used to focus, deflect or spin-polarise the broad bandwidth neutron beams, and typical incident spectra are presented for each configuration. A series of neutron reflectivity datasets are presented, indicating the quality and flexibility of this spectrometer. Minimum reflectivity values of <10 -7 are observed; while maximum thickness values of 325 nm have been measured for single-component films and 483 nm for a multilayer system. Off-specular measurements have also been made to investigate in-plane features as opposed to those normal to the sample surface. Finally, the first published studies conducted using the Platypus time-of-flight neutron reflectometer are presented.

    Single tablet regimens (STRs) for HIV infection improve patient satisfaction, quality of life, medication adherence, and virological suppression compared to multitablet regimens (MTRs). This is the first study assessing STR uptake and durability in Australia. This retrospective audit of all patients receiving an STR (n = 299) at a large Sydney HIV clinic (January 2012–December 2013) assessed patient demographics, treatment prior to STR, HIV RNA load and CD4 during MTR and STR dosing, and reasons for STR switch. 206 patients switched from previous antiretroviral treatment to an STR, of which 88% switched from an MTR. Reasons for switching included desire to simplify treatment (57%), reduced side effects or toxicity (18%), and cost-saving for the patient. There was no switching for virological failure. Compared to when on an MTR, patients switching to an STR had significantly lower HIV RNA counts (p < 0.001) and significantly higher CD4 counts (p < 0.001). The discontinuation rate from STR was very low and all patients who switched to an STR maintained virological suppression throughout the study duration, although the study is limited by the absence of a control group.

    The verification of the Comprehensive Nuclear-Test Ban Treaty (CTBT) relies amongst other things on the continuous and worldwide monitoring of radioxenon. The characterization of the existing and legitimate background, which is produced mainly by nuclear power plants and isotope production facilities, is of high interest to improve the capabilities of the monitoring network. However, the emissions from legitimate sources can usually only be estimated. For this paper historic source terms of (133)Xe emissions from the isotope production facility at ANSTO, Sydney, Australia, have been made available in a daily resolution. Based on these high resolution data, different source term sets with weekly, monthly and yearly time resolution have been compiled. These different sets are then applied together with atmospheric transport modelling (ATM) to predict the concentration time series at two radioxenon monitoring stations. The results are compared with each other in order to examine the improvement of the prediction capability depending on the used time resolution of the most dominant source term in the region.

    Background Australia has a hot climate with maximum summer temperatures in its major cities frequently exceeding 35°C. Although ‘heat waves’ are an annual occurrence, the associated heat-related deaths among vulnerable groups, such as older people, suggest that Australians could be better prepared to deal with extreme heat. Objective To understand ways in which a vulnerable sub-population adapt their personal behaviour to cope with heat within the context of Australians’ relationship with heat. Design We draw upon scientific, historical and literary sources and on a set of repeat interviews in the suburbs of Western Sydney with eight older participants and two focus group discussions. We discuss ways in which this group of older people modifies their behaviour to adapt to heat, and reflect on manifestations of Australians’ ambivalence towards heat. Results Participants reported a number of methods for coping with extreme heat, including a number of methods of personal cooling, changing patterns of daily activity and altering dietary habits. The use of air-conditioning was near universal, but with recognition that increasing energy costs may become more prohibitive over time. Conclusions While a number of methods are employed by older people to stay cool, these may become limited in the future. Australians’ attitudes may contribute to the ill-health and mortality associated with excessive heat. PMID:23078748

    Iron oxide minerals typically compose only a few weight percent of bulk atmospheric dust but are important for potential roles in forcing climate, affecting cloud properties, influencing rates of snow and ice melt, and fertilizing marine phytoplankton. Dust samples collected from locations across eastern Australia (Lake Cowal, Orange, Hornsby, and Sydney) following the spectacular "Red Dawn" dust storm on 23 September 2009 enabled study of the dust iron oxide assemblage using a combination of magnetic measurements, Mössbauer spectroscopy, reflectance spectroscopy, and scanning electron microscopy. Red Dawn was the worst dust storm to have hit the city of Sydney in more than 60 years, and it also deposited dust into the Tasman Sea and onto snow cover in New Zealand. Magnetization measurements from 20 to 400 K reveal that hematite, goethite, and trace amounts of magnetite are present in all samples. Magnetite concentrations (as much as 0.29 wt%) were much higher in eastern, urban sites than in western, agricultural sites in central New South Wales (0.01 wt%), strongly suggesting addition of magnetite from local urban sources. Variable temperature Mössbauer spectroscopy (300 and 4.2 K) indicates that goethite and hematite compose approximately 25-45% of the Fe-bearing phases in samples from the inland sites of Orange and Lake Cowal. Hematite was observed at both temperatures but goethite only at 4.2 K, thereby revealing the presence of nanogoethite (less than about 20 nm). Similarly, hematite particulate matter is very small (some of it d < 100 nm) on the basis of magnetic results and Mössbauer spectra. The degree to which ferric oxide in these samples might absorb solar radiation is estimated by comparing reflectance values with a magnetic parameter (hard isothermal remanent magnetization, HIRM) for ferric oxide abundance. Average visible reflectance and HIRM are correlated as a group (r2 = 0.24), indicating that Red Dawn ferric oxides have capacity to absorb solar radiation. Much of this ferric oxide occurs as nanohematite and nanogoethite particles on surfaces of other particulate matter, thereby providing high surface area to enhance absorption of solar radiation. Leaching of the sample from Orange in simulated human-lung fluid revealed low bioaccessibility for most metals.

    We report the first confirmed case of toxoplasmosis in an Australian pinniped. Presence of Toxoplasma gondii DNA was detected in the brain of a free-ranging subadult New Zealand fur seal (Arctocephalus forsteri) with nonsuppurative meningoencephalitis, hypophysitis, posterior uveitis, retrobulbar cellulitis, and myocarditis associated with protozoan cysts and tachyzoites. The emaciated seal stranded moribund on a beach in northern Sydney in New South Wales. Histopathology coupled with specific immunohistochemistry and PCR assays confirmed the presence of T. gondii. The T. gondii sample (NZfs8825) identified in this study has an identical genotype as the type II (ToxoDB PCR-RFLP genotype #1) based on the direct sequencing and virtual RFLP of multilocus DNA markers including SAG1, 5'- and 3'-SAG2, alt.SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1, and Apico. Direct sequencing of T. gondii B1 DNA marker from the T. gondii sample (NZfs8825) identified a type II-like strain, based on presence of non-archetypal B1 gene polymorphisms previously reported as unique to Australia. This study suggests that T. gondii oocysts originating from mainland Australia, which has a large population of feral cats, may act as a disease threat to native marine fauna. Therefore, emerging toxoplasmosis in the Arctic has a relevant parallel in the Southern Ocean within Australian waters with yet unknown relevance to Antarctica. PMID:25123611

  18. The background pattern of drug usage in Australia.

    The pattern of drug usage by urban populations has been studied in two typical Australian cities: Traralgon, Victoria, and Sydney, New South Wales. The study, lasting 1 year, involved questioning of 10% of the residents in households selected by random sampling and records of pharmacists. The questions related to state of health, recurrent or chronic disability, and drug exposures during 2 wk preceding the interview. Figures obtained from the Pharmaceutical Benefit Scheme (a system of partial federal subsidy) and the Morbidity Survey of the Royal Australasian College of General Practitioners showed Australians to be near the top of the world's drug takers, in comparison for example with Americans: between 6 and 7 prescriptions per capita in Australia and between 4 and 5 prescriptions in the United States in 1973. The consumption of over-the-counter drugs (OTC) was estimated from the Commonwealth Statistician's figures by subtracting the expenditure for prescription drugs from the total annual chemist sales--$A450,000,000. This represents a cost of $A33.85 for every man, woman, and child. Of this amount $A19.07 was spent for OTC drugs, analgesics and cough suppressants being the two largest items. Roughly 60% of Australians average two or more doses of analgesics per day, with some patients consuming 12 or more doses a day. An association between this high consumption of analgesics and an alarming incidence of iatrogenic disease--analgesic nephropathy and gastrointestinal hemorrhage--is postulated. It is concluded that this level of drug usage must be symptomatic of underlying stresses and pressures of urban society in that country, along with a cultural factor of ready acceptance of the social use of drugs.

  19. Diagnosing coastal ocean CO2 interannual variability from a 40 year hydrographic time series station off the east coast of Australia

    NASA Astrophysics Data System (ADS)

    McNeil, Ben I.

    2010-12-01

    Advancing our understanding of the ocean's role in modulating atmospheric carbon dioxide interannual variability is important but limited by the lack of temporal ocean CO2 observations throughout most of the world's oceans. In particular, the role of the coastal ocean for interannual variability of CO2 is unknown, but expected to be large given the dynamics of land to ocean CO2 exchanges. Two coastal hydrographic time series stations at Port Hacking off Sydney, Australia, have collected and measured hydrographic properties (temperature, salinity, nitrate, phosphate, and silicate) since 1942. Here I examine the potential to use empirical relationships derived from nearby discrete CO2 measurements to diagnose CO2 interannual variability at the Port Hacking time series station. I test the approach by predicting interannual variability of CO2 at the Bermuda Time Series Station (BATS) in the North Atlantic between 1988 and 2008 and show the method captures 78% of the observed interannual variability found at BATS. I further use oxygen as a tracer to diagnose the length scales of variability in the southwest Pacific to provide insight into the applicability of the method. After applying the approach at Port Hacking, significant CO2 interannual variability was found (up to ± 30 ppm) that was largely driven by local regional variability in nutrients (nitrate) and temperature with little link to larger modes of variability (SAM or ENSO). Oceanic CO2 was diagnosed to be almost always lower than atmospheric CO2 levels (?pCO2 ˜ 10-55 ?atm), indicating a quasi-permanent coastal ocean CO2 sink during winter off Sydney. Direct pCO2 measurements taken along the NSW coastline in April and August 2008 confirm the empirical predictions and a wider CO2 sink along Australia's east coast. If extrapolating the Port Hacking CO2 results to the New South Wales coastline, the annual coastal CO2 sink would be about -0.05 Tg C/yr. Both the empirical predictions and direct measurements of CO2 presented here along the Australian east coast support recent reviews suggesting continental shelves act as a significant CO2 sink, at least during autumn and winter.

  20. Differing approaches to falls and fracture prevention between Australia and Colombia.

    Falls and fractures are major causes of morbidity and mortality in older people. More importantly, previous falls and/or fractures are the most important predictors of further events. Therefore, secondary prevention programs for falls and fractures are highly needed. However, the question is whether a secondary prevention model should focus on falls prevention alone or should be implemented in combination with fracture prevention. By comparing a falls prevention clinic in Manizales (Colombia) versus a falls and fracture prevention clinic in Sydney (Australia), the objective was to identify similarities and differences between these two programs and to propose an integrated model of care for secondary prevention of fall and fractures. A comparative study of services was performed using an internationally agreed taxonomy. Service provision was compared against benchmarks set by the National Institute for Health and Clinical Excellence (NICE) and previous reports in the literature. Comparison included organization, administration, client characteristics, and interventions. Several similarities and a number of differences that could be easily unified into a single model are reported here. Similarities included population, a multidisciplinary team, and a multifactorial assessment and intervention. Differences were eligibility criteria, a bone health assessment component, and the therapeutic interventions most commonly used at each site. In Australia, bone health assessment is reinforced whereas in Colombia dizziness assessment and management is pivotal. The authors propose that falls clinic services should be operationally linked to osteoporosis services such as a "falls and fracture prevention clinic," which would facilitate a comprehensive intervention to prevent falls and fractures in older persons.

  1. Beyond the Biomedical Paradigm: The Formation and Development of Indigenous Community-Controlled Health Organizations in Australia.

    Khoury, Peter

    2015-01-01

    This article describes the formation and development of Aboriginal Community-Controlled Health Services in Australia, with emphasis on the Redfern Aboriginal Medical Service in Sydney. These organizations were established in the 1970s by Indigenous Australians who were excluded from and denied access to mainstream health services. The aim of this research was to explore notions of Indigenous agency against a historical backdrop of dispossession, colonialism, and racism. Aboriginal Community-Controlled Health Services act as a primary source of healthcare for many Indigenous communities in rural and urban areas. This study examined their philosophy of healthcare, the range of services provided, their problems with state bureaucracies and government funding bodies, and the imposition of managerialist techniques and strategies on their governance. Essentially, these organizations transcend individualistic, biomedical, and bureaucratic paradigms of health services by conceptualizing and responding to Indigenous health needs at a grassroots level and in a broad social and political context. They are based on a social model of health. PMID:26077856

    Fishing and resource use continues to be an essential aspect of life for many Aboriginal communities throughout Australia. It is important for dietary sustenance, and also retains deep social, cultural and economic significance, playing a fundamental role in maintaining group cohesion, transferring cultural knowledge and affirming Indigenous identities. We surveyed approximately 20% of the Gumbaynggirr Aboriginal community of Nambucca Heads, New South Wales, Australia. This paper explores Gumbaynggirr Connection to Country and engagement in cultural practice. It quantifies fishing efforts and consumption of seafood within the community. We found 95% of the sample group fish, with the highest rate of fishing being 2-3 times a week (27%). Furthermore, 98% of participants eat seafood weekly or more frequently, up to more than once a day (24%). Survey results revealed that Myxus elongatus (Sand mullet) and naturally recruited Saccostrea glomerata (Sydney rock oysters) continue to be important wild resources to the Gumbaynggirr community. Trace metals were measured in M. elongatus and S. glomerata samples collected by community participants in this study. Maximum levels prescribed in the Australia New Zealand Food Standards Code were not exceeded in the edible tissue for either species, however both species exceeded the generally expected levels for zinc and copper and S. glomerata samples exceeded the generally expected level for selenium. Furthermore the average dietary exposure to trace metals from consuming seafood was calculated for the surveyed population. Trace metal intake was then compared to the provisional tolerable weekly intake prescribed by the Joint Expert Committee on Food Additives. This process revealed that copper and selenium intake were both within the provisional tolerable weekly intake, while there is no guideline for zinc. Furthermore, participants relying heavily on wild resources from the Nambucca River estuary may exceed the provisional tolerable weekly intake for cadmium. This suggests the need for further investigation of this issue to minimize any possible health risk. PMID:26098897

    This cross-sectional study aimed to compare dietary intake in people living with HIV (PLHIV) experiencing symptoms of depression with those not reporting depression. The Centre for Epidemiologic Studies Depression Scale (CES-D10) was used to classify the risk of depression. Dietary nutrient intake was determined using the diet history and food frequency questionnaire. Depressed (n = 21) compared with non-depressed (n = 37) subjects had significantly lower mean intake of fibre (16.1 versus 25.4 g/day), vitamin A (801.5 versus 1524.8 mg/day), magnesium (299.8 versus 380.0 mg/day) and folate (264.8 versus 402.9 ?g/day). The proportion of subjects achieving the recommended intake of these nutrients, with the exception of folate was also found to be lower in the depressed group compared with non-depressed group. The study found that depressive symptomatology in PLHIV was associated with poorer dietary nutrient intake. A multidisciplinary model of care that includes a nutrition assessment is recommended for the management of PLHIV with depression to reduce the risk of associated nutritional problems. PMID:23258829

    Current in situ methods used to geotechnically characterize the ground are predominantly based on invasive mechanical techniques (e.g. CPT, SPT, DMT). These techniques are localized to the tested area thus making it quite time consuming and costly to extensively cover large areas. Hence, a study has been initiated to investigate the use of the non-invasive Multichannel Analysis of Surface Waves (MASW) and Multichannel Simulation with One Receiver (MSOR) techniques to provide both an evaluation of compacted ground and a general geotechnical site characterization. The MASW technique relies on the measurement of active ambient vibrations generated by sledgehammer hits to the ground. Generated vibrations are gathered by interconnected electromagnetic geophones set up in the vertical direction and in a linear array at the ground surface with a constant spacing. The MSOR technique relies on one sensor, one single geophone used as the trigger, and multiple impacts are delivered on a steel plate at several distances in a linear array. The main attributes of these non-invasive techniques are the cost effectiveness and time efficiency when compared to current in situ mechanical invasive methods. They were applied to infer the stiffness of the ground layers by inversion of the phase velocity dispersion curves to derive the shear wave velocity (Vs) profile. The results produced by the MASW and the MSOR techniques were verified against independent mechanical Cone Penetration Test (CPT) and Standard Penetration Test (SPT) data. This paper identifies that the MASW and the MSOR techniques could be potentially useful and powerful tools in the evaluation of the ground compaction and general geotechnical site characterization.

    Persistent organic pollutants (i.e. PCBs, DDTs, and HCHs) were analyzed along Australia and New Zealand North Island coastlines. PCB concentrations were high in urban areas (107-294ng/g-pellet), with Sydney Harbour the most polluted. Hepta-chlorinated PCB was abundant, with ~30% in urban areas suggesting legacy pollution. DDT concentrations showed similar pattern except in rural agricultural sites, Taupo Bay and Ahipara, New Zealand (23 and 47ng/g-pellet). p,p'-DDE predominance at these 2 sites suggested historical input; they also had high HCH concentrations (17 and 29ng/g-pellet). The role of International Pellet Watch (IPW) in science communication was studied through feedbacks from IPW volunteers, case studies and examples. IPW data were categorized into understandable terms and tailored reports based on volunteers' backgrounds complemented with pollution maps. The effectiveness of IPW science communication has led to its use in awareness and education activities focusing on both POPs and plastic debris issues. PMID:26586511

    Despite tremendous growth in the consumption of gluten-free (GF) foods, there is a lack of evaluation of their nutritional profile and how they compare with non-GF foods. The present study evaluated the nutritional quality of GF and non-GF foods in core food groups, and a wide range of discretionary products in Australian supermarkets. Nutritional information on the Nutrition Information Panel was systematically obtained from all packaged foods at four large supermarkets in Sydney, Australia in 2013. Food products were classified as GF if a GF declaration appeared anywhere on the product packaging, or non-GF if they contained gluten, wheat, rye, triticale, barley, oats or spelt. The primary outcome was the 'Health Star Rating' (HSR: lowest score 0.5; optimal score 5), a nutrient profiling scheme endorsed by the Australian Government. Differences in the content of individual nutrients were explored in secondary analyses. A total of 3213 food products across ten food categories were included. On average, GF plain dry pasta scored nearly 0.5 stars less (P< 0.001) compared with non-GF products; however, there were no significant differences in the mean HSR for breads or ready-to-eat breakfast cereals (P? 0.42 for both). Relative to non-GF foods, GF products had consistently lower average protein content across all the three core food groups, in particular for pasta and breads (52 and 32% less, P< 0.001 for both). A substantial proportion of foods in discretionary categories carried GF labels (e.g., 87% of processed meats), and the average HSR of GF discretionary foods were not systematically superior to those of non-GF products. The consumption of GF products is unlikely to confer health benefits, unless there is clear evidence of gluten intolerance. PMID:26119206

  4. Structural evolution of the early Permian Nambucca Block (New England Orogen, eastern Australia) and implications for oroclinal bending

    The Paleozoic to early Mesozoic southern New England Orogen of eastern Australia exhibits a remarkable ear-shaped curvature (orocline), but the geodynamic processes responsible for its formation are unclear. Oroclinal bending took place during the early Permian, simultaneously with the deposition of the rift-related Sydney, Gunnedah, and Bowen basins, which bound the oroclines to the west. The Nambucca Block is another early Permian rift basin, but it is situated in the core of the oroclinal structure. Here we present new stratigraphic, structural, and geochronological data from the Nambucca Block in an attempt to better understand its tectonic history and relationships to the formation of the oroclines. We recognized four phases of folding and associated structural fabrics (S1-4), with the second phase (S2) dated at 275-265 Ma by 40Ar/39Ar geochronology of muscovite. This age overlaps with independent constraints on the timing of oroclinal bending, suggesting that the earlier two phases of deformation in the Nambucca Block (F1 and F2) were associated with orocline formation. We propose that oroclinal bending involved three major stages. The first stage (<300 Ma) was associated with variations in rates of trench rollback and formation of rift basins in a hot extensional back-arc setting. This was followed by a second stage of oroclinal bending, possibly linked to dextral wrench faulting, which involved ~ N-S contraction (F1). Subsequent deformation at 275-265 Ma involved formation of nappe-style structures (F2). This phase of contractional deformation may have resulted from an increased plate coupling that was possibly linked to flat-slab subduction.

  5. Minority stress in lesbian, gay, and bisexual young adults in Australia: associations with psychological distress, suicidality, and substance use.

    Lesbian, gay, bisexual, and other same-sex attracted young people have been shown to be at a higher risk of mental health problems, including depression, anxiety, suicidality, and substance abuse, compared to their heterosexual peers. Homophobic prejudice and stigma are often thought to underlie these disparities. In this study, the relationship between such experiences of social derogation and mental health and substance use in same-sex attracted young people was examined using Meyer's minority stress theory. An online survey recruited 254 young women and 318 young men who identified as same-sex attracted, were aged 18-25 years, and lived in Sydney, Australia. Multivariate logistic regression analyses showed that internalized homophobia, perceived stigma, and experienced homophobic physical abuse were associated with higher levels of psychological distress and self-reported suicidal thoughts in the previous month. Furthermore, perceived stigma and homophobic physical abuse were associated with reporting a lifetime suicide attempt. The association between minority stress and substance use was inconsistent. While, as expected, higher levels of perceived stigma were associated with club drug dependence, there was an inverse association between internalized homophobia and club drug use, and between perceived stigma and hazardous alcohol use. The findings of this study provide support for the minority stress theory proposition that chronic social stress due to sexual orientation is associated with poorer mental health. The high rates of mental health and substance use problems in the current study suggest that same-sex attracted young people should continue to be a priority population for mental health and substance use intervention and prevention.

  8. The Acid Test: pH Tolerance of the Eggs and Larvae of the Invasive Cane Toad (Rhinella marina) in Southeastern Australia.

    Invasive cane toads are colonizing southeastern Australia via a narrow coastal strip sandwiched between unsuitable areas (Pacific Ocean to the east, mountains to the west). Many of the available spawning sites exhibit abiotic conditions (e.g., temperature, salinity, and pH) more extreme than those encountered elsewhere in the toad's native or already invaded range. Will that challenge impede toad expansion? To answer that question, we measured pH in 35 ponds in northeastern New South Wales and 8 ponds in the Sydney region, in both areas where toads occur (and breed) and adjacent areas where toads are likely to invade, and conducted laboratory experiments to quantify effects of pH on the survival and development of toad eggs and larvae. Our field surveys revealed wide variation in pH (3.9-9.8) among natural water bodies. In the laboratory, the hatching success of eggs was increased at low pH (down to pH 4), whereas the survival, growth, and developmental rates of tadpoles were enhanced by higher pH levels. We found that pH influenced metamorph size and shape (relative head width, relative leg length) but not locomotor performance. The broad tolerance range of these early life-history stages suggests that pH conditions in ponds will not significantly slow the toad's expansion southward. Indeed, toads may benefit from transiently low pH conditions, and habitat where pH in wetlands is consistently low (such as coastal heath) may enhance rather than reduce toad reproductive success. A broad physiological tolerance during embryonic and larval life has contributed significantly to the cane toad's success as a widespread colonizer. PMID:26052640

    Objectives This prospective cohort study aimed to investigate whether there are differences in health outcomes among persons with mild or moderate injuries who were hospitalised compared with those not hospitalised following a road traffic crash. Setting Sydney Metropolitan, New South Wales, Australia. Participants Persons aged ?18?years involved in a motor vehicle crash were surveyed at baseline (n=364), and at 12 (n=284) and 24?months (n=252). A telephone-administered questionnaire obtained information on a range of socioeconomic, and preinjury and postinjury psychological and heath characteristics of all participants. Primary outcome measure Participants who reported admission to hospital for 24?h or more (but less than 7?days) after the crash were classified as being hospitalised; those admitted for less than 24?h were classified as non-hospitalised. Results Around 1 in 5 participants (19.0%) were hospitalised for ?24?h after the crash. After adjusting for age and sex, hospitalised participants compared with those not hospitalised had approximately 2.6?units (p=0.01) lower Short Form-12 Physical Component Summary (SF-12 PCS) scores (poorer physical well-being) and approximately 4.9?units lower European Quality of Life visual analogue scale (EQ-VAS) scores (p=0.05), 12?months later. After further adjusting for education level, whiplash, fracture and injury severity score, participants who were hospitalised had approximately 3.3?units lower SF-12 PCS (p=0.04), 12?months later. The association with EQ-VAS did not persist after multivariable adjustment. No significant differences were observed between the 2 groups in health outcomes at 24-month follow-up. Conclusions These findings indicate that long-term health status is unlikely to be influenced by hospitalisation status after sustaining a mild/moderate injury in a vehicle-related crash.

    In recent years the role of extreme events such as tsunamis and storms in shaping coastal evolution and change has been increasingly appreciated. Around the world, tsunami geologists are increasingly recognising the signatures of palaeotsunamis almost everywhere they look and in many cases, base their interpretations on similar evidence for Quaternary tsunamis first identified in Australia. Geological research suggests that the coast of south east Australia and others worldwide may have been impacted by palaeotsunamis many times larger than the catastrophic 2004 Indian Ocean and 2011 T?hoku events. In Australia, the debate centres on the hypothesis that the coast of south east Australia preserves evidence for repeated, large magnitude Quaternary tsunamis. If independently validated, this hypothesis has profound implications for risk. Despite the potential importance of this hypothesis, no synthesis or comprehensive review of the proposed geological evidence and chronology exists. As a result it is difficult to assess the evidence and to draw conclusions about the nature of the hazard and risk along the coast. This synthesis details the spatial distribution of reported palaeotsunami deposits along the coast of New South Wales, south east Australia and summarises the distribution of different types of sedimentary and erosional evidence. The age range of reported palaeotsunami deposits is identified and mapped before discussing 'same age' (chronologically correlated) deposits. These data are then used to draw broad conclusions about the evidence and identify future research questions to aid in the testing of the hypothesis for repeated tsunami inundation. We show that 60 sites are purported to contain evidence of tsunami inundation over 650 km of the south east Australian coast with a spatial concentration south of Sydney. Geomorphic evidence, distinctly different to that used elsewhere in global palaeotsunami studies, is reported at 54 sites, with erosional features described as the most frequent indication of inundation. Proposed tsunami deposits are evident at 44 sites, with the dominant deposit type being imbricated boulder stacks. Radiocarbon dating at 39 of the sites led to a proposition of nine events during the Quaternary, eight of which occurred during the Holocene. Interestingly, 18 sites have no chronological data associated with them. Alternative interpretations are offered at six type field sites purported to contain palaeotsunami evidence. Attention is drawn to the disjunct between historical and geological scales of tsunami inundation in the region in addition to the contrast between the scale of reported palaeotsunamis and the robust evidence of smaller events. A synthesis of research into the nature of the evidence is offered, including critiques of evidence type and mechanisms. A critical review of the chronological data is also presented, in addition to the recalibration and analysis of published radiocarbon data. The paper concludes with an outline of research questions for further work on proposed palaeotsunami sites in Australia as well as a statement about likely risk in south east Australia. It also advocates the need for caution when interpreting evidence for palaeotsunamis elsewhere around the world when those interpretations are based on signatures originally reported in south east Australia.

    South-central Australia is home to several deserts, including the Simpson Desert, whose reddish-orange sands are seen in the upper left quadrant of this Moderate Resolution Imaging Spectroradiometer (MODIS) image from July 1, 2002. Several impermanent, salty, lakes stand whitely out against the arid terrain. The largest is North Lake Eyre, southwest of center. At bottom center, Spencer Gulf separates the triangular Eyre Peninsula from the Yorke Peninsula. The Gulf of St. Vincent separates Yorke Peninsula from the mainland. In Spencer Gulf, colorful blue-green swirls indicate the presence of a bloom of marine plants called phytoplankton, whose brightly colored photosynthetic pigments stain the water. Water quality in the Gulf is an ongoing problem for Australia, as irrigation projects have diverted the already small flow of freshwater that empties into the Gulf. Other problems include contamination with pesticides and agricultural and residential fertilizer. On both the Eyre Peninsula and in the Victoria Territory to the east of Spencer Gulf, dark-colored rectangles show the boundaries of parks and nature preserves where the natural, drought-tolerant vegetation thrives.

    Higher levels of macrophage inhibitory cytokine-1, also known as growth differentiation factor 15 (MIC-1/GDF15), are associated with adverse health outcomes and all-cause mortality. The aim of this study was to examine the relationships between MIC-1/GDF15 serum levels and global cognition, five cognitive domains, and mild cognitive impairment (MCI), at baseline (Wave 1) and prospectively at 2 years (Wave 2), in nondemented participants aged 70-90 years. Analyses were controlled for age, sex, education, Framingham risk score, history of cerebrovascular accident, acute myocardial infarction, angina, cancer, depression, C-reactive protein, tumor necrosis factor-?, interleukins 6 and 12, and apolipoprotein ?4 genotype. Higher MIC-1/GDF15 levels were significantly associated with lower global cognition at both waves. Cross-sectional associations were found between MIC-1/GDF15 and all cognitive domains in Wave 1 (all P < 0.001) and between processing speed, memory, and executive function in Wave 2 (all P < 0.001). Only a trend was found for the prospective analyses, individuals with high MIC-1/GDF15 at baseline declined in global cognition, executive function, memory, and processing speed. However, when categorizing MIC-1/GDF15 by tertiles, prospective analyses revealed statistically significant lower memory and executive function in Wave 2 in those in the upper tertile compared with the lower tertile. Receiver operating characteristics (ROC) analysis was used to determine MIC-1/GDF15 cutoff values associated with cognitive decline and showed that a MIC-1/GDF15 level exceeding 2764 pg/ml was associated with a 20% chance of decline from normal to MCI or dementia. In summary, MIC-1/GDF15 levels are associated with cognitive performance and cognitive decline. Further research is required to determine the pathophysiology of this relationship. PMID:23758647

    AIM: To report a single Australian oncology unit’s experience with the management of patients with hepatocellular carcinoma (HCC), in the context of a literature review of the current management issues. METHODS: Retrospective case record review of 76 patients with diagnosis of HCC referred to the unit between 1984 and 1995. RESULTS: Sixty-three patients had adequate records for analysis. Thirty-six (56%) were migrants with half from Southeast Asia. Twenty-four p atients had a documented viral aetiology. Nine (14%) of 51 patients with pathological confirmation of HCC had normal alpha-fetoprotein levels. Median survival of the 20 patients managed palliatively was 5 weeks compared to 16 weeks for the cohort overall. Surgery in 16 patients rendered all initially disease free with a median survival of 88 weeks. Chemoembolisation induced tumor responses in 5 of the 11 patients so treated. Systemic chemotherapy and tamoxifen treatment caused tumor response in two of 12 and one of 25 respectively. CONCLUSION: Prolonged survival of patients with HCC depends on early detection of small tumors suitable for surgical resection. Other active t reatments are palliative in intent and have limited success. In addition to tumor response and survival duration, the toxicities of therapies and the overall quality of life of patients need to be considered as important outcomes. Viral hepatitis prevention and screening of individuals at risk are strategies that are important for HCC management in communities where the disease is endemic. PMID:11819496

  14. Deciphering the crustal structure of the Tasmanides in southeastern Australia with anisotropic short-period Rayleigh wave tomography

    NASA Astrophysics Data System (ADS)

    The Tasmanides of Australia were formed by a series of tectonic supercycles that determined the crustal - and probably the lithospheric - structure of the eastern third of the Australian continent during the Phanerozoic. In southeast Australia, the Tasmanides essentially consist of the Delamerian, Lachlan and New England orogens whose mutual boundaries are obscured by the presence of large Mesozoic to Cenozoic sedimentary basins: the Sydney Basin at the boundary separating the Lachlan and the New England orogens, and the Murray Basin at the boundary between the Delamerian and the Lachlan orogens. In this work, we exploit the ambient noise wavefield recorded by the largest transportable seismic array experiment in the southern hemisphere, which has operated in eastern Australia from 1998 to present and involves the deployment of over 700 temporary stations with an average interstation distance of about 50 km. We analyze Rayleigh wave phase dispersion curves obtained in a previous study on more than 8,200 cross-correlograms using data from 450 sites, and we perform an anisotropic tomography inversion for periods ranging from 1 to 20 s in order to account for the apparent dependence of Rayleigh wavespeeds on azimuthal propagation direction. The resulting maps allow us to identify several crustal elements in terms of lateral extent, wavespeed and anisotropy. The Archean Gawler Craton and Proterozoic Curnamona Province, as well as the Eastern and Central Subprovinces of the Lachlan Orogen, are characterized by high velocities, while the Western Subprovince of the Lachlan Orogen and the Adelaide Fold Belt exhibit lower velocities. The transition from Delamerian to Lachlan orogens is marked by a clear change from high to low velocity and a change in anisotropy pattern, especially in the northern sector of the model. In the western Lachlan subprovince, the fast direction changes from SE-NW in the South to SW-NE in the North, and follows the orientation of its boundary with the Delamerian Orogen. This suggests that the proto-Pacific margin of east Gondwana was significantly curved, in contrast with the consistently NS fast axis orientation of the eastern Lachlan Orogen that suggests a more linear margin. It also appears that crustal anisotropy in the Lachlan Orogen was not significantly affected by events that have followed its formation such as Cenozoic volcanism or the separation between Australia and Antarctica. Largely on the basis of high resolution aeromagnetic maps, several recent studies have identified the possible presence of a remnant fragment of Precambrian lithosphere - possibly originating from the break-up of Rodinia - embedded within the Lachlan Orogen. Intriguingly, our anisotropic tomography results show the fast axis of anisotropy almost mimicking the magnetic lineations which appear to wrap around a region that is now referred to as the Hay-Booligal Zone. The close correlation between the patterns of azimuthal anisotropy and lineations identified in potential field data is one of the most remarkable outcomes of this high resolution study.

  15. Twenty two cases of canine neural angiostronglyosis in eastern Australia (2002-2005) and a review of the literature

    PubMed Central

    2012-01-01

    Cases of canine neural angiostrongylosis (NA) with cerebrospinal fluid (CSF) evaluations in the peer-reviewed literature were tabulated. All cases were from Australia. A retrospective cohort of 59 dogs was contrasted with a series of 22 new cases where NA was diagnosed by the presence of both eosinophilic pleocytosis and anti-Angiostrongylus cantonensis immunloglobulins (IgG) in CSF, determined by ELISA or Western blot. Both cohorts were drawn from south east Queensland and Sydney. The retrospective cohort comprised mostly pups presented for hind limb weakness with hyperaesthesia, a mixture of upper motor neurone (UMN) and lower motor neurone (LMN) signs in the hind limbs and urinary incontinence. Signs were attributed to larval migration through peripheral nerves, nerve roots, spinal cord and brain associated with an ascending eosinophilic meningo-encephomyelitis. The contemporary cohort consisted of a mixture of pups, young adult and mature dogs, with a wider range of signs including (i) paraparesis/proprioceptive ataxia (ii) lumbar and tail base hyperaesthesia, (iii) multi-focal central nervous system dysfunction, or (iv) focal disease with neck pain, cranial neuropathy and altered mentation. Cases were seen throughout the year, most between April and July (inclusive). There was a preponderance of large breeds. Often littermates, or multiple animals from the same kennel, were affected simultaneously or sequentially. A presumptive diagnosis was based on consistent signs, proximity to rats, ingestion/chewing of slugs or snails and eosinophilic pleocytosis. NA was diagnosed by demonstrating anti-A. cantonensis IgG in CSF. Detecting anti-A. cantonensis IgG in serum was unhelpful because many normal dogs (20/21 lb dogs; 8/22 of a hospital population) had such antibodies, often at substantial titres. Most NA cases in the contemporary series (19/22) and many pups (16/38) in the retrospective cohort were managed successfully using high doses of prednisolone and opioids. Treatment often included antibiotics administered in case protozoan encephalomyelitis or translocated bacterial meningitis was present. Supportive measures included bladder care and physiotherapy. Several dogs were left with permanent neural deficits. Dogs are an important sentinel species for NA. Human cases and numerous cases in tawny frogmouths were reported from the same regions as affected dogs over the study period. PMID:22480148

  12. An outbreak of cholera in Australia due to food served in flight on an international aircraft

    1974-01-01

    An outbreak of cholera occurred in November 1972 among passengers on an aircraft that had flown from London to Sydney. The infection was confined to economy-class passengers and the available evidence indicates that it was due to a dish of hors d'œuvres served on the aircraft between Bahrain and Singapore. Although one person died, the infection was generally mild, and almost half of those infected were symptomless. There was a significant difference between the immunization status of persons with clinical illness and the immunization status of other passengers. Current cholera immunization appeared to play a significant role in preventing symptoms of the disease, but it did not prevent a person becoming a carrier of the organism. PMID:4526408

    Simple Summary Records from road transport of horses from Perth to Sydney over a two year period were analysed to explore the incidence of transport related issues and identify risk factors. Transportation resulted in health problems in 2.8% of the transported horses, and in fatalities in 0.24%. Journey duration and season were risk factors for the development of transport related health problems, while breed, sex and age did not predict disease or injury risk. Overall, this study provides statistics to inform policy development for the equine transport industry and enhance management of the transported horse. Abstract Equine transportation is associated with a variety of serious health disorders causing economic losses. However; statistics on horse transport are limited and epidemiological data on transport related diseases are available only for horses transported to abattoirs for slaughter. This study analysed reports of transport related health problems identified by drivers and horse owners for 180 journeys of an Australian horse transport company transporting horses between Perth and Sydney (~4000 km) in 2013–2015. Records showed that 97.2% (1604/1650) of the horses arrived at their destination with no clinical signs of disease or injury. Based on the veterinary reports of the affected horses; the most common issues were respiratory problems (27%); gastrointestinal problems (27%); pyrexia (19%); traumatic injuries (15%); and death (12%). Journey duration and season had a significant effect on the distribution of transport related issues (p < 0.05); with a marked increase of the proportion of the most severe problems (i.e., gastrointestinal; respiratory problems and death) in spring and after 20 h in transit. Although not statistically significant; elevated disease rate predictions were seen for stallions/colts; horses aged over 10 years; and Thoroughbreds. Overall; the data demonstrate that long haul transportation is a risk for horse health and welfare and requires appropriate management to minimize transport stress. PMID:26690482

  14. Provenance and structural constraints of the early Permian Nambucca Block (eastern Australia), and implications for the origin of the New England oroclines

    NASA Astrophysics Data System (ADS)

    2014-05-01

    The late Paleozoic to early Mesozoic southern New England Orogen of eastern Australia exhibits a remarkable omega-shaped orogenic curvature (orocline), but the geodynamic processes responsible for the formation of the orogenic curvatures (oroclines) are still unclear. Oroclinal bending took place during the early Permian, simultaneously with the development of rift-related sedimentary basins (Sydney, Gunnedah and Bowen basins), which bound the oroclines to the west. The Nambucca Block is part of another early Permian rift basin that is situated farther east, in the core of the oroclinal structure. We present new stratigraphic, structural and geochronological data from the Nambucca Block in an attempt to better understand its provenance, tectonic history and its role in the formation of the oroclines. Four phases of folding and associated structural fabrics are recognised in the Nambucca Block. 40Ar/39Ar age of metamorphic micas from the second deformational phase provides a minimum depositional age constraint at 275-265 Ma. This age overlaps with the timing of oroclinal bending, suggesting that the first two phases of deformation resulted from the same mechanism that formed the oroclines. Detrital zircon geochronology (U/Pb ICP-MS ages) of six samples from the Nambucca Block constrains the maximum depositional age of the sequence to 280 Ma. The sedimentary succession, though extremely polymictic, is unimodal in its sources, and is therefore interpreted to consist mainly of recycled detritus from a Devonian-Carboniferous accretionary complex. We propose a model for oroclinal bending involving three stages. The first stage, starting at about 293 Ma and including the deposition of the sequence of Nambucca (i.e. overlaps with the 280-265 Ma time constraint), was associated with formation of rift basins in an extensional backarc setting. This was followed by N-S contraction, which gave rise to second-order oroclinal structures. The third and final stage involved contractional deformation that gave rise to recumbent folds and penetrative sub-horizontal structural fabrics at 275-265 Ma and further tightened the oroclinal structure.

  18. Fugitive methane emissions from natural, urban, agricultural, and energy-production landscapes of eastern Australia

    Modern cavity ringdown spectroscopy systems (CRDS) enable the continuous measurement of methane concentration. This allows for improved quantification of greenhouse gas emissions associated with various natural and human landscapes. We present a subset of over 4000 km of continuous methane surveying along the east coast of Australia, made using a Picarro G2301 CRDS, deployed in a utility vehicle with an air inlet above the roof at 2.2 mAGL. Measurements were made every 5 seconds to a precision of <0.5 ppb for CH4. These surveys were undertaken during dry daytime hours and all measurements were moisture corrected. We compare the concentration of methane in the near surface atmosphere adjacent to open-cut coal mines, unconventional gas developments (coal seam gas; CSG), and leaks detected in cities and country towns. In areas of dryland crops the median methane concentration was 1.78 ppm, while in the irrigation districts located on vertisol soils the concentration was as low as 1.76 ppm, which may indicate that these soils are a sink for methane. In the Hunter Valley, New South Wales, open-cut coal mining district we mapped a continuous 50 km interval where the concentration of methane exceeded 1.80 ppm. The median concentration in this interval was 2.02 ppm. Peak readings were beyond the range of the reliable measurement (in excess of 3.00 ppm). This extended plume is an amalgamation of plumes from 17 major pits 1 to 10 km in length. Adjacent to CSG developments in the Surat Basin, southeast Queensland, only small anomalies were detected near the well-heads. Throughout the vast majority of the gas fields the concentration of methane was below 1.80 ppm. The largest source of fugitive methane associated with CSG was off-gassing methane from the co-produced water holding ponds. At one location the down wind plume had a cross section of approximately 1 km where the concentration of methane was above 1.80 ppm. The median concentration within this section was 1.82 ppm, with a peak reading of 2.11 ppm. The ambient air methane concentration was always higher in urban environments compared to the surrounding countryside. Along one major road in Sydney we mapped an interval that extended for 6 km where the concentration was greater than 1.80 ppm. The median concentration in this interval was 1.90 ppm, with a peak reading of 1.97 ppm. This high reading in an urban setting is most likely due to leaks from the domestic gas distribution system. Methane leaks were detected in all country towns. Our measurements show that at the point of resource extraction the methane emission footprint of CSG is smaller than that of open-cut coal mining. However, leaking gas from urban centers must be added to the fugitive emissions of CSG to calculate the total fugitive emission footprint of CSG, which may therefore not be as low as claimed in the national greenhouse gas accounts. Our results highlight the need for additional continuous monitoring of methane emissions from all sectors, and for the full life-cycle of energy resources to be considered.

  19. Relative importance of natural and anthropogenic influences on the fresh surface water chemistry of the Hawkesbury-Nepean River, south-eastern Australia.

    1998-07-01

    Fresh surface waters from the Hawkesbury-Nepean River, the major river supplying water to the Sydney region in south-eastern Australia, were sampled monthly during 1991 and analysed for major ions (Na, K, Ca, Mg, Cl, SO4 and HCO3), nutrients (NO3 and PO4), organic carbon and trace metals (Al, Fe, Cu, Zn, Pb, Cd, Ni, Co and Mn). The chemical composition of the river during 1991 was consistent with other studies of the river from 1977 to 1996. The major ion composition in the river is predominantly influenced by sea-salt aerosols in rainwater (headwaters) and connate sea-salt in groundwater (mid-lower reaches), with a cationic dominance order of Na > Mg > Ca > K (equivalents) and an anionic order of Cl > HCO3 > SO4. This is typical of the headwaters of other permanent coastal rivers (freshwater) in south-eastern Australia with a similar catchment lithology. These results differ markedly from the most common natural major ion assemblages established for world rivers (i.e. Ca > Mg > Na > K and HCO3 > SO4 > Cl), which tend to be predominantly influenced by chemical weathering of rocks and minerals. The mean concentrations of major ions, nutrients, organic carbon and trace metals in the freshwater reaches of the Hawkesbury-Nepean River increased by factors of 2.5-4.4, 14-18, 2.2 and 1.6-11, respectively, with increasing distance from the headwaters. Increases in major ion concentrations are attributed mainly to the increasing influence of saline groundwater inflows from regions of Wianamatta shale. Conversely, concentrations of nutrients, organic carbon and trace metals (except Fe and Al) increased as a consequence of anthropogenic inputs, particularly point discharges from sewage treatment plants (i.e. showing distinct, but variable, concentration peaks), as well as diffuse urban and/or agricultural runoff during storm events. The temporal variability of the mean concentrations of all measured parameters in this study was related to variability in water discharge. The mean concentrations of the major ions decreased by a factor of 1.5-3.0 with increasing water discharge, whereas the concentrations of nutrients, organic carbon and trace metals increased by a factor of 2.0-3.0, 1.6 and 1.3-2.0, respectively. This study provides the first survey of trace metal concentrations in the freshwater reaches of a permanent coastal river in Australia using 'clean' sampling and handling techniques. The concentrations of Cu, Zn, Pb, Cd and Ni measured in the headwaters of the Hawkesbury-Nepean River were amongst the lowest reported in the literature for riverine (freshwater) systems, and will form a benchmark for assessing the effects of increasing urbanisation in the catchment.

  1. Analysis of long-term water quality for effective river health monitoring in peri-urban landscapes--a case study of the Hawkesbury-Nepean river system in NSW, Australia.

    PubMed

    2013-06-01

    The Hawkesbury-Nepean River (HNR) system in South-Eastern Australia is the main source of water supply for the Sydney Metropolitan area and is one of the more complex river systems due to the influence of urbanisation and other activities in the peri-urban landscape through which it flows. The long-term monitoring of river water quality is likely to suffer from data gaps due to funding cuts, changes in priority and related reasons. Nevertheless, we need to assess river health based on the available information. In this study, we demonstrated how the Factor Analysis (FA), Hierarchical Agglomerative Cluster Analysis (HACA) and Trend Analysis (TA) can be applied to evaluate long-term historic data sets. Six water quality parameters, viz., temperature, chlorophyll-a, dissolved oxygen, oxides of nitrogen, suspended solids and reactive silicates, measured at weekly intervals between 1985 and 2008 at 12 monitoring stations located along the 300 km length of the HNR system were evaluated to understand the human and natural influences on the river system in a peri-urban landscape. The application of FA extracted three latent factors which explained more than 70 % of the total variance of the data and related to the 'bio-geographical', 'natural' and 'nutrient pollutant' dimensions of the HNR system. The bio-geographical and nutrient pollution factors more likely related to the direct influence of changes and activities of peri-urban natures and accounted for approximately 50 % of variability in water quality. The application of HACA indicated two major clusters representing clean and polluted zones of the river. On the spatial scale, one cluster was represented by the upper and lower sections of the river (clean zone) and accounted for approximately 158 km of the river. The other cluster was represented by the middle section (polluted zone) with a length of approximately 98 km. Trend Analysis indicated how the point sources influence river water quality on spatio-temporal scales, taking into account the various effects of nutrient and other pollutant loads from sewerage effluents, agriculture and other point and non-point sources along the river and major tributaries of the HNR. Over the past 26 years, water temperature has significantly increased while suspended solids have significantly decreased (p?
