Across the dividing range - bridging the divides: Pharmacy opportunities across the hospital/community and inter-professional divides in rural and remote Australia

Rural and remote areas of Australia offer many opportunities for innovation in healthcare services. Some true healthcare 'network' models based around rural pharmacy can be established and evaluated. The lines between community and hospital pharmacy are often blurred and communication between health professionals enhanced. The blurring divide between hospital and community pharmacy in rural and remote areas has provided significant advances in practice. Projects have been set up to investigate the feasibility of community pharmacists integrating care for patients. These projects take advantage of the dual roles and the enhanced interaction between pharmacists and other health professionals in the bush. Opportunities for provision of clinical services beyond the traditional supply role have been taken in a number of remote communities

Hypertension, dyslipidemia, body mass index, Diabetes and smoking status in aboriginal australians in a remote community

Objectives: Study objectives were: 1) to describe the differences in the prevalence of CHID risk factors between Aboriginal people in a remote community and the general Australian population; and 2) to compare the predicted risks of CHD events between Aboriginal and non-Aboriginal Australians. Design: A cross-sectional study. Participants: 681 Aboriginal adults aged 25 to 74 years. Results: Aboriginal young adults had substantially higher prevalence of diabetes compared to non-Aboriginal Australians. The prevalence ratios for diabetes were 12.5, 5.6, 3.2, 1.3, and 0.73 for 25-, 35-, 45-, 55-, and 65- to 74-year-old females, respectively, The corresponding values for males were 12.1, 2.7, 2.9, 0.69, and 0.42. Young females had a higher prevalence of obesity, overweight, and abnormal waist circumference, while males and females 45 years and older tended to have a lower prevalence of overweight and ab. normal waist circumference. Compared to the general population, Aboriginal adults had a lower prevalence of abnormal total cholesterol but a higher prevalence of abnormal HDL, triglycerides, hypertension, and smoking. The risk ratios of abnormal total cholesterol for females ages 2534, 35-44, 45-54, 55-64, and 65-75 years were 0.38, 0.53, 0.48, 0.48, and 0.41, respectively. Conclusions: Aboriginal people in the remote community experienced different levels of CHD risk predictors from the general Australian population. They had a lower prevalence of abnormal total cholesterol and a higher prevalence of abnormal HDL, smoking, diabetes, and hypertension.

Validation of self-reported cigarette smoking in a remote Australian Aboriginal community

Objective: To examine the relationship between self-reported tobacco smoking and urinary cotinine concentrations in the setting of a remote Aboriginal community. Methods: In a remote Northern Territory (NT) Aboriginal community the relationship between self-reported tobacco smoking and urinary cotinine concentrations was examined as part of a cross-sectional survey of cardiovascular risk factors. Current tobacco smoking was assessed as part of a questionnaire. The concentration of cotinine and cotinine/creatinine ratio (CCR) in a spot urine sample were used as a biochemical marker of nicotine exposure. Results: A total of 237 people took part in the survey, although completed questionnaires and urine results were available for 184 people. Current tobacco smoking was reported by 161 (69 [95% Cl 63 to 75]%) people, with higher rates among males (84/104, 81 [95% Cl 72 to 88]%) than females (77/129, 60 [95% Cl 51 to 68]%, p

Renal function and cardiovascular risk markers in a remote Australian Aboriginal community

Background. Australian Aborigines living in remote areas have exceedingly high rates of renal failure together with increased cardiovascular morbidity and mortality. To examine the basis of this association, we studied markers of renal function and cardiovascular (CV) risk in a coastal Aboriginal community in a remote area of the Northern Territory of Australia. End-stage renal disease (ESRD) incidence rates in that community are 15 times the national non-Aboriginal rate and CV mortality rates in the region are increased 5-fold. Methods. A cross-sectional community survey was conducted. Markers of early renal disease examined included urine albumin/creatinine ratio (ACR), serum creatinine concentration and calculated glomerular filtration rate (GFR). CV risk markers included blood pressure as well as measures of glycaemia, diabetes and serum lipids. Results. The study group included 237 people, 58% of the adult population of the community. The crude prevalence of microalbuminuria (urine ACR: 3.4-33.9 g/mol, 30-299 mg/g) was 31% and of overt albuminuria (urine ACR: greater than or equal to34 g/mol, greater than or equal to300 mg/g), 13%. The prevalence of overt albuminuria increased with age, but the prevalence of microalbuminuria was greatest in the 45-54 year age group. Microalbuminuria was associated with increasing body mass index, whereas overt albuminuria was associated with increasing glycated haemoglobin (HbA1c) and systolic blood pressure and a history of diabetes. The prevalence of elevated serum creatinine concentration (greater than or equal to120 mumol/l) was 10%. GFR (calculated using the MDRD equation) was <60 ml/min/1.73m(2) in 12% and 60-79 ml/min/1.73 m(2) in a further 36% of the study population. Although many people with albuminuria had well preserved GFRs, mean GFR was lower in people with higher levels of albuminuria. Conclusions. The high prevalence of markers of renal disease in this community was consistent with their high rates of ESRD. The distribution of microalbuminuria suggested a 'cohort effect', representing a group who will progress to overt albuminuria. The powerful association of renal disease markers with CV risk factors confirms a strong link between renal and CV disease in the early, asymptomatic stages of each. Thus, pathologic albuminuria, in part, might be a manifestation of the metabolic/haemodynamic syndrome and both conditions might arise out of a common menu of risk factors. Hence, a single agenda of primary and secondary intervention may benefit both.

Developing New Tourism Services: Dinosaurs a New Drive Tourism Resource for Remote Areas

This paper examines issues encountered when developing new tourism services generally, and specific aspects relating to the development of remote area dinosaur fossil fields for tourism. It studies two sites, one in the USA and one in Australia. Access to both sites is by minor roads, and both sites are characterised by long drives separating the sites from small communities that offer limited infrastructure and few other attractions for visitors. In both areas, however, tourism is seen as one of the few possible ways to sustain existing communities in the face of declining primary-industry-based employment. In general, tourists visiting these areas are on touring holidays of two weeks’ duration or more where the attraction is the general attributes of the region as well as to a lesser extent their interest in dinosaur fossils. These provide a potential resource for remote-region economic development through commodification as a new tourism attraction. Development of dinosaur fossil finds as a tourism resource is conceptualised here as new service development. Developing new tourism services, especially in remote regions, is challenging and has not been well examined in the tourism literature. The new service development process used in this case study first examines the characteristics of the existing tourists travelling through the region. The characteristics of a number of potential market segments currently interested in dinosaur fossils were then examined and contrasted with the existing market. This is conceptualised on a specialist-generalist spectrum of interest in fossils. A study of the tourist service features associated with dinosaur fossil tourism in remote regions of the USA was conducted, leading to the identification of a number of possible incremental development opportunities. The paper then takes a strategic approach to examining potential new tourism service development related to dinosaur fossils in remote regions of Queensland, Australia. In particular, it describes use of information about existing services in similar regions as the basis for ideas about development as well as comparison between existing and potential markets.

C-reactive protein, cardiovascular risk, and renal disease in a remote Australian Aboriginal community

Rates of cardiovascular and renal disease in Australian Aboriginal communities are high, but we do not know the contribution of inflammation to these diseases in this setting. In the present study, we sought to examine the distribution of C-reactive protein (CRP) and other markers of inflammation and their relationships with cardiovascular risk markers and renal disease in a remote Australian Aboriginal community. The study included 237 adults (58% of the adult population) in a remote Aboriginal community in the Northern Territory of Australia. Main outcome measures were CRP, fibrinogen and lgG concentrations, blood pressure (BP), presence of diabetes, lipids, albuminuria, seropositivity to three common micro-organisms, as well as carotid intima-media thickness (IMT). Serum concentrations of CRP [7 (5-13) mg/l; median (inter-quartile range)] were markedly increased and were significantly correlated with fibrinogen and lgG concentrations and inversely correlated with serum albumin concentration. Higher CRP concentrations were associated with lgG seropositivity to Helicobacter pylori and Chlamydia pneumoniae and higher lgG titre for cytomegalovirus. Higher CRP concentrations were associated with the following: the 45-54-year age group, female subjects, the presence of skin sores, higher body mass index, waist circumference, BP, glycated haemoglobin and greater albuminuria. CRP concentrations increased with the number of cardiovascular risk factors, carotid IMT and albuminuria independently of other risk factors. These CRP concentrations were markedly higher than described in other community settings and are probably related, in a large part, to chronic and repeated infections. Their association with markers of cardiovascular risk and renal disease are compatible with the high rates of cardiovascular and renal disease in this community, and provide more evidence of strong links between these conditions, through a shared background of infection/inflammation. This suggests that a strong focus on prevention and management of infections will be important in reducing these conditions, in addition to interventions directed at more traditional risk factors.

Carotid intima-media thickness, cardiovascular risk factors and albuminuria in a remote Australian Aboriginal community

Background: Rates of cardiovascular disease and renal disease in Australian Aboriginal communities are high, as is the prevalence of some 'traditional' cardiovascular (CV) risk factors, such as diabetes and cigarette smoking. Recent work has highlighted the importance of markers of inflammation, such as C-reactive protein (CRP), homocysteine and albuminuria as predictors of cardiovascular risk in urban westernised settings. It is not clear how these factors relate to outcome in the setting of these remote communities, but very high CRP concentrations have been shown in this and other Aboriginal communities. Methods and results: In a cross-sectional survey including 237 adults in a remote Aboriginal community in the Northern Territory of Australia, we measured carotid intima-media thickness (IMT), together with blood pressure, diabetes, lipid levels, smoking and albuminuria, CRP and fibrinogen, serum homocysteine concentration, and IgG titres for Chlamydia pneumoniae, Helicobacter pylori and cytomegalovirus. Median carotid IMT was 0.63 [interquartile range 0.54-0.71] mm. As a categorical outcome, the prevalence of the highest IMT quartile ('increased IMT', greater than or equal to0.72 mm) was compared with the lower three quartiles. Increased IMT was associated in univariate analyses with greater waist circumference, systolic BP, fibrinogen and serum albumin concentrations, urine albumin/creatinine ratio and older age as continuous variables. Associations of increased IMT with some continuous variables were not linear; univariate associations were seen with the highest quartile (versus all other quartiles) of CRP and homocysteine concentration and CMV IgG titre. In a multivariate model age, smoking, waist circumference and the highest quartile of CRP concentrations (greater than or equal to14 mg/l) remained significant predictors of IMT greater than or equal to0.72 mm. Conclusions: Measurement of carotid IMT was possible in this remote setting. Increased IMT (greater than or equal to0.72 mm) was associated with increased CRP concentrations over a range that suggests infection/inflammation may be important determinants of cardiovascular risk in this setting. The associations of IMT with markers of renal disease seen in univariate analyses were explained in this analysis by confounding due to the associations of urine ACR with other risk factors.

Resources required for exact remote state preparation

It has been shown [M.-Y. Ye, Y.-S. Zhang, and G.-C. Guo, Phys. Rev. A. 69, 022310 (2004)] that it is possible to perform exactly faithful remote state preparation using finite classical communication and any entangled state with maximal Schmidt number. Here we give an explicit procedure for performing this remote state preparation. We show that the classical communication required for this scheme is close to optimal for remote state preparation schemes of this type. In addition we prove that it is necessary that the resource state have maximal Schmidt number.

Maintaining and updating semantic context in schizophrenia: an investigation of the effects of multiple remote primes

Conflicting findings regarding the ability of people with schizophrenia to maintain and update semantic contexts have been due, arguably, to vagaries within the experimental design employed (e.g. whether strongly or remotely associated prime-target pairs have been used, what delay between the prime and the target was employed, and what proportion of related prime-target pairs appeared) or to characteristics of the participant cohort (e.g. medication status, chronicity of illness). The aim of the present study was to examine how people with schizophrenia maintain and update contextual information over an extended temporal window by using multiple primes that were either remotely associated or unrelated to the target. Fourteen participants with schizophrenia and 12 healthy matched controls were compared across two stimulus onset asynchronies (SOAs) (short and long) and two relatedness proportions (RP) (high and low) in a crossed design. Analysis of variance statistics revealed significant two- and three-way interactions between Group and SOA, Group and Condition, SOA and RP, and Group, SOA and RP. The participants with schizophrenia showed evidence of enhanced remote priming at the short SOA and low RP, combined with a reduction in the time course over which context could be maintained. There was some sensitivity to biasing contextual information at the short SOA, although the mechanism over which context served to update information appeared to be different from that in the controls. The participants with schizophrenia showed marked performance decrements at the long SOA (both low and high RP). Indices of remote priming at the short (but not the long) SOA correlated with both clinical ratings of thought disorder and with increasing length of illness. The results support and extend the hypothesis that schizophrenia is associated with concurrent increases in tonic dopamine activity and decreases in phasic dopamine activity.

Application of remote sensing and GIS in mineral resource mapping - An overview

Remote sensing, as a direct adjunct to field, lithologic and structural mapping, and more recently, GIS have played an important role in the study of mineralized areas. A review on the application of remote sensing in mineral resource mapping is attempted here. It involves understanding the application of remote sensing in lithologic, structural and alteration mapping. Remote sensing becomes an important tool for locating mineral deposits, in its own right, when the primary and secondary processes of mineralization result in the formation of spectral anomalies. Reconnaissance lithologic mapping is usually the first step of mineral resource mapping. This is complimented with structural mapping, as mineral deposits usually occur along or adjacent to geologic structures, and alteration mapping, as mineral deposits are commonly associated with hydrothermal alteration of the surrounding rocks. In addition to these, understanding the use of hyperspectral remote sensing is crucial as hyperspectral data can help identify and thematically map regions of exploration interest by using the distinct absorption features of most minerals. Finally coming to the exploration stage, GIS forms the perfect tool in integrating and analyzing various georeferenced geoscience data in selecting the best sites of mineral deposits or rather good candidates for further exploration.
