A study involving 64 Australian sex offenders and 33 non-sex offenders found childhood emotional abuse and family dysfunction, childhood behavior problems, and childhood sexual abuse were developmental risk factors for paraphilia. Emotional abuse and family dysfunction was found to be a risk factor for pedophilia, exhibitionism, rape, or multiple paraphilia. (Contains references.) (CR)

Transport infrastructure is pivotal for economic and social development. Over the past decade, Public-Private Partnerships (PPPs) have been widely adopted for its delivery in developing and developed economies due to increasingly limited public budgets. Therefore, deciding whether to use PPPs is a critical topic for governments and relies on an essential criterion that is referred to as value for money (VfM). However, the complexity of transport infrastructure projects renders the current VfM -oriented decision-making tool (i.e., public sector comparator) to be a less-than-comprehensive assessment. Thus, a total of five case studies of transport PPPs in Australia are undertaken in this paper to interpret existing practice. The empirical evidences indicate that the VfM -based assessment being widely used is ineffective in capturing: (1) key stakeholders' (e.g., client and asset end-users) expectations, and (2) the underlying dynamics of complexities of transport projects. Accordingly, a novel decision-making model that emphasizes asset service quality and usage is mathematically developed. Relevant implications for improving current practice have also been discussed. This research contributes to the existing body of knowledge in terms of ex-ante evaluation of infrastructure projects and can be useful for enhancing the effectiveness of government's decision-making about the employment of PPPs for transport assets.

Public–Private Partnerships (PPPs) have become a critical vehicle for delivering infrastructure worldwide. Yet, the use of such a procurement strategy has received considerable criticism, as they have been prone to experiencing time/cost overruns and during their operation poorly managed. A key issue contributing to the poor performance of PPPs is the paucity of an effective and comprehensive performance measurement system. There has been a tendency for the performance of PPPs to be measured based on theirex-postcriteria of time, cost and quality. Such criteria do not accommodate the complexities and lifecycle of an asset. In addressing this problem, the methodology of sequential triangulation is used to develop and examine the effectiveness of a ‘Process Management Life Cycle Performance Measurement System’. The research provides public authorities and private-sector entities embarking on PPPs with a robust mechanism to effectively measure, control and manage their projects’ life cycle performances, ensuring the assets are ‘future proofed’.

Objective: We aimed to describe the prevalence and age distribution of personality disorders and their comorbidity with other psychiatric disorders in an age-stratified sample of Australian women aged ⩾25 years. Methods: Individual personality disorders (paranoid, schizoid, schizotypal, histrionic, narcissistic, borderline, antisocial, avoidant, dependent, obsessive-compulsive), lifetime mood, anxiety, eating and substance misuse disorders were diagnosed utilising validated semi-structured clinical interviews (Structured Clinical Interview for DSM-IV-TR Axis I Disorders, Research Version, Non-patient Edition and Structured Clinical Interview for DSM-IV Axis II Personality Disorders). The prevalence of personality disorders and Clusters were determined from the study population (n = 768), and standardised to the Australian population using the 2011 Australian Bureau of Statistics census data. Prevalence by age and the association with mood, anxiety, eating and substance misuse disorders was also examined. Results: The overall prevalence of personality disorders in women was 21.8% (95% confidence interval [CI]: 18.7, 24.9). Cluster C personality disorders (17.5%, 95% CI: 16.0, 18.9) were more common than Cluster A (5.3%, 95% CI: 3.5, 7.0) and Cluster B personality disorders (3.2%, 95% CI: 1.8, 4.6). Of the individual personality disorders, obsessive-compulsive (10.3%, 95% CI: 8.0, 12.6), avoidant (9.3%, 95% CI: 7.1, 11.5), paranoid (3.9%, 95% CI: 3.1, 4.7) and borderline (2.7%, 95% CI: 1.4, 4.0) were among the most prevalent. The prevalence of other personality disorders was low (⩽1.7%). Being younger (25–34 years) was predictive of having any personality disorder (odds ratio: 2.36, 95% CI: 1.18, 4.74), as was being middle-aged (odds ratio: 2.41, 95% CI: 1.23, 4.72). Among the strongest predictors of having any personality disorder was having a lifetime history of psychiatric disorders (odds ratio: 4.29, 95% CI: 2.90, 6.33). Mood and anxiety disorders were the most common comorbid lifetime psychiatric disorders. Conclusions: Approximately one in five women was identified with a personality disorder, emphasising that personality disorders are relatively common in the population. A more thorough understanding of the distribution of personality disorders and psychiatric comorbidity in the general population is crucial to assist allocation of health care resources to individuals living with these disorders.

This study investigated social perspective coordination (SPC) in youth (15-24-year-olds) with first-presentation borderline personality disorder (BPD). SPC is defined as the capacity to differentiate and integrate the perspective of the self with the perspectives of others (Selman, Beardslee, Schultz, Krupa, & Podorefsky, 1986). Two groups: patients with full or sub-syndromal BPD ( n == 30) and patients with major depressive disorder (MDD; n == 30) completed measures of SPC derived from the interpersonal negotiation strategies (INS) model (Selman et al., 1986). Compared with the MDD group, the BPD group responded to all vignettes with significantly lower SPC scores and SPC was a significant predictor of BPD status over and above self-reported, personality factors (Neuroticism and Agreeableness), attachment disturbance and functional impairment. These findings suggest that disturbances in social cognition are an important characteristic of individuals with BPD pathology. These difficulties extended beyond attachment contexts and were not limited to situations involving BPD-related themes of abandonment, deprivations or mistrust/abuse. [ABSTRACT FROM AUTHOR]

Objective: To investigate the relationship between childhood trauma, post-traumatic stress symptoms due to the experience of childhood trauma, and post-traumatic stress symptoms due to the experience of psychosis.Method: The current study assessed childhood trauma and post-traumatic stress disorder (PTSD) symptoms as a result of both childhood trauma and psychosis using the Impact of Events Scale - Revised, in a group of 36 people with first-episode psychosis.Results: Reported rates of clinical level post-psychotic PTSD symptoms, childhood trauma and childhood trauma-related clinical level PTSD symptoms were 47% (95% CI 31–64%), 64% (95% CI 48–80%) and 39% (95% CI 23–55%), respectively. Reporting childhood trauma increased the risk of developing post-psychosis PTSD 27-fold (95% CI 2.96–253.80, p = 0.01). Having childhood trauma-related PTSD increased the risk of developing post-psychosis PTSD 20-fold (95% CI 3.38–123.25, p = 0.01). These risks were not explained by illness factors such as duration of untreated psychosis, age of onset or severity of psychotic symptoms. Those without post-psychotic PTSD symptoms at clinical levels were unlikely to report childhood trauma (6%; 95% CI 3–8%).Conclusions: These results suggest the cognitive, social and biological consequences of childhood trauma can prevent effective recovery from the trauma of acute first-episode psychosis resulting in post-psychotic PTSD. Treatment strategies for post-psychotic PTSD must address childhood trauma and related PTSD. [ABSTRACT FROM PUBLISHER]

The authors reflect on the assessment of the Better Access scheme, which was sponsored by the Commonwealth Department of Health and Aging. The authors remark that because of poor methodology, there are numerous questions which were not answered by Better Access's evaluation. Meanwhile, the authors mention the editorial of Tony Jorm which points out that the scheme has been more expensive compared to what was expected.

Background: The aim of the present study was to examine in a national survey sample the risks of having a specific personality disorder (PD) and associations with gender, of having one or more physical conditions, of having one or more Axis 1 conditions, and of the severity (or degree) of disability. We also examined the association of specific PDs with having sought a consultation for health or mental health problems with a general practitioner (GP), a psychologist, or psychiatrist over the past 12 months.Method: Data were derived from the Australian National Mental Health and Well-Being Survey, conducted between May and August 1997. A stratified random sample of households was generated, from which all persons aged 18 or over were considered potential interviewees. There were 10,641 survey respondents, this representing a response rate of 78%. Each interviewee was asked 59 questions indexing specific ICD-10 PD criteria.Results: Logistic regressions identified that some specific PDs, especially borderline PD, were more strongly associated with having one or more Axis I conditions, greater mental disability and lost days of total and partial role functioning than having No PD, and that others, notably anankastic PD, were less likely to be associated with the same variables. Some specific PDs, again most notably borderline PD, were more associated than others, again most notably anankastic PD, with having sought mental health consultations from GPs, psychiatrists, and psychologists. By contrast, PD associations with gender, physical conditions, physical disability and health consultations with the three professional groups were weaker as reflected in the comparatively smaller odds ratios and were also less consistent than the pattern with the previously mentioned variables.Conclusion: The study reports findings from a nationwide survey and, as such, the data are less influenced by the selection and setting bias found in most other studies investigating these variables. The findings of the study do point to some specific PDs, such as borderline PD, being associated with greater Axis 1 psychopathology, disability and mental health consultations than others, such as anankastic PD. It appears that although anankastic PD in itself is associated with more disability than having No PD, it becomes significantly more disabling when it is associated with other comorbid PDs.

Objective: High prevalence disorders (anxiety, depressive and substance use) are generally assumed to be more common in urban than rural dwellers. The aims of this paper are (i) to critically review studies measuring prevalence in rural as opposed to urban location, and (ii) to argue the need to look beyond the ‘quantity’ question to the quality question: how does urban or rural place influence mental health? Method: A literature review (Medline and PsychLIT) was carried out using the words ‘rural, urban, mental/psychiatric, illness/disorders and prevalence’, as well as a review of relevant papers and publications known to the authors. Results: Many studies examining urban/rural differences in the rate of high prevalence disorders have been reported. Most use a ‘one size fits all’ definition of urban and rural, which assumes location is the key issue. The majority fail to show the purported difference in prevalence between the two settings. In general, studies have not examined interaction effects, but have simply treated the independent variables as main effects. Available data suggest that a variety of socio-demographic factors are more powerful predictors of difference in prevalence than is the location of residence. Conclusion: Further studies are required to understand if and how rural or urban place contributes to the development of psychiatric morbidity. These studies should mirror the clinical situation by taking into account a variety of individual and community-based (including urban/rural place) risk factors which may be important determinants of mental health and mental illness, and examining the interaction between them. This may then identify the nature of any differences or what issues are specific to, or especially important, in the rural setting. [ABSTRACT FROM AUTHOR]

Due to the restricted nature of illicit drugs, it is difficult to conduct research surrounding the analysis of this drug material for any potential DNA in sufficient quantities acceptable for high numbers of replicates. Therefore, the current research available in peer reviewed journals thus far regarding analysing illicit drugs for DNA has been performed under varying experimental conditions, often using surrogate chemicals in place of illicit drugs. The data presented within this study originated from the analysis of genuine illicit drugs prepared both in controlled environments and those seized at the Australian border (and therefore from an uncontrolled environment) to determine if DNA can be obtained from this type of material. This study has been separated into three main parts (total n=114 samples): firstly, methamphetamine synthesised within a controlled environment was spiked with both saliva and trace DNA to determine the yield following DNA extraction; secondly, methamphetamine also synthesised in a controlled environment but on a larger scale was tested for the amount of DNA added incidentally throughout the synthesis, including the additional steps of recrystallising, homogenising and "cutting" the drug material to simulate preparation for distribution; and thirdly, the detection of human DNA within samples of cocaine and heroin seized at the Australian border. The DNA Fast Flow Microcon Device was utilised to concentrate all replicates from the same source into one combined extract to improve the DNA profiles for the samples where no DNA spiking occurred. Full STR profiles were successfully obtained from drug samples spiked with both saliva and trace DNA. Methamphetamine was present in the final DNA extracts and caused incompatibilities with the quantification of DNA using Qubit. The yields of DNA from drugs not spiked with DNA sources were much lower, resulting in 36 % of samples yielding alleles where all others did not. These results were not unexpected given these were realistic drug samples where the history of the drug material was unknown. This is the first study to obtain DNA profiles from genuine illicit drug material in both controlled and uncontrolled environments and indicates that the analysis of illicit drugs for DNA is an avenue worth pursuing to provide information which can in turn assist with disrupting the supply of these drugs. Given that DNA profiling is carried out worldwide using essentially the same systems as described within this study, the potential for impact is on a national and international scale., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Purpose: To examine the association between muscle fiber typology and match running performance in professional Australian football (AF) athletes., Methods: An observational time-motion analysis was performed on 23 professional AF athletes during 224 games throughout the 2020 competitive season. Athletes were categorized by position as hybrid, small, or tall. Athlete running performance was measured using Global Navigation Satellite System devices. Mean total match running performance and maximal mean intensity values were calculated for moving mean durations between 1 and 10 minutes for speed (in meters per minute), high-speed-running distance (HSR, >4.17 m·s-1), and acceleration (in meters per second squared), while intercept and slopes were calculated using power law. Carnosine content was quantified by proton magnetic resonance spectroscopy in the gastrocnemius and soleus and expressed as a carnosine aggregate z score (CAZ score) to estimate muscle fiber typology. Mixed linear models were used to determine the association between CAZ score and running performance., Results: The mean (range) CAZ score was -0.60 (-1.89 to 1.25), indicating that most athletes possessed a greater estimated proportion of type I muscle fibers. A greater estimated proportion of type I fibers (ie, lower CAZ score) was associated with a larger accumulation of HSR (>4.17 m·s-1) and an increased ability to maintain HSR as the peak period duration increased., Conclusion: AF athletes with a greater estimated proportion of type I muscle fibers were associated with a greater capacity to accumulate distance running at high speeds, as well as a greater capacity to maintain higher output of HSR running during peak periods as duration increases.

Recent years have seen escalating media, public and scientific interest in psychedelic medicine. Australia and New Zealand have been late to this research; however, in the past 2 years, rapid developments suggest that this is changing. Here, we argue for the need to critically review existing evidence in this field to guide future directions. We focus on (±)3,4-methylenedioxymethamphetamine-assisted psychotherapy for post-traumatic stress disorder, currently the most advanced area of clinical psychedelic research. Food and Drug Administration approval of this approach is likely in 2023, based on a series of promising findings. We provide a detailed overview of Phase 2 and 3 studies published to date. We identify several concerns related to this body of evidence, including methodological/design limitations and broader factors - such as robust involvement of advocacy groups in research and reliance on non-government financing leading to simplistic public messaging - that compound the methodological issues identified. We propose steps for future improvement, including the need for large, high-quality, independent efficacy trials with design enhancements, effectiveness trials and for researchers to consider their own engagement with media and public messaging around these modalities. We argue that, notwithstanding promising findings to date, rigorous and dispassionate science is needed to move the field forward and safeguard the welfare of participants.

Purpose: The aim of this systematic review was to (1) determine the muscle fiber-type composition (or muscle fiber typology [MFT]) of team-sport athletes and (2) examine associations between MFT and the physical characteristics and performance tasks in team-sport athletes., Methods: Searches were conducted across numerous databases-PubMed, SPORTDiscus, MEDLINE, and Google Scholar-using consistent search terms. Studies were included if they examined the MFT of team-sport athletes. Included studies underwent critical appraisal using the McMasters University critical appraisal tool for quantitative research., Results: A total of 10 studies were included in the present review, wherein the MFT of athletes was measured from 5 different team sports (soccer, rugby union, rugby league, handball, and volleyball). There was large variability in the MFT of team-sport athletes both within (up to 27.5%) and between sports (24.0% relative difference). Male football players with a higher proportion of type II fibers had faster 10- and 30-m sprint times, achieved a greater total distance sprinting (distance at >6.67 m·s-1), and a greater peak 1-minute sprint distance., Conclusions: MFT varies considerably between athletes both within and between different team sports. The results from some studies suggest that variation in MFT is associated with high-intensity running performance in a football match, as well as 10- and 30-m sprint times. Further experimental studies should focus on how determination of the MFT of team-sport athletes could be utilized to influence talent identification, team selection, and the individualization of training.

Due to technical limitations, there have been minimal studies performed on thermal preferences and thermotactic behaviors of aquatic ectotherm species commonly used in ecotoxicity testing. In this work, we demonstrate an innovative, purpose-built and miniaturized electrothermal array for rapid thermal preference behavioral tests. We applied the novel platform to define thermal preferences in multiple invertebrate and vertebrate species. Specifically, Dugesia notogaea (freshwater planarians), Chironomus tepperi (nonbiting midge larvae), Ostracoda (seed shrimp), Artemia franciscana (brine shrimp), Daphnia carinata (water flea), Austrochiltonia subtenuis (freshwater amphipod), Physa acuta (freshwater snail), Potamopyrgus antipodarum (New Zealand mud snail) and larval stage of Danio rerio (zebrafish) were tested. The Australian freshwater water fleas, amphipods, snail Physa acuta as well as zebrafish exhibited the most consistent preference to cool zones and clear avoidance of zones >27 °C out of nine species tested. Our results indicate the larval stage of zebrafish as the most responsive species highly suitable for prospective development of multidimensional behavioral test batteries. We also showcase preliminary data that environmentally relevant concentrations of pharmaceutical pollutants such as non-steroidal anti-inflammatory drug (NSAID) ibuprofen (9800 ng/L) and insecticide imidacloprid (4600 ng/L) but not anti-depressant venlafaxine (2200 ng/L) and (iv) anticonvulsant medications gabapentin (400 ng/L) can perturb thermal preference behavior of larval zebrafish. Collectively our results demonstrate the utility of simple and inexpensive thermoelectric technology in rapid exploration of thermal preference in diverse species of aquatic animals. We postulate that more broadly such technologies can also have added value in ecotoxicity testing of emerging contaminants., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd.

Capsules are now the main form of ecstasy rather than tablets in Australia and therefore their examination is of interest to forensic drug chemists in Australia and possibly elsewhere. Recently, we used controlled experimental conditions to show that capsules may be a source of DNA that can be used to identify those involved in production and distribution of illicit drugs. The question remains: in realistic scenarios where there are more unknowns, can we still detect DNA, and determine whose it is, on the exterior of capsules? The concept of comprehensive forensic intelligence and investigations - utilizing both biological and chemical signatures - relating to illicit drug preparations (i.e., the capsules and their contents) may be of great use to law enforcement. Experiments were conducted with both semi-realistic and realistic scenarios where two volunteers were asked to firstly use an encapsulator and mimic the loading of capsules, then Volunteer 1 would count out the capsules that Volunteer 2 prepared, and vice versa. This was to simulate the scenario where one person was involved in the assembly of the capsules which were then separated into smaller bags of 10 capsules by a second person for distribution. Gelatine and vegetable capsules were tested, with 10 replicates used per capsule type, scenario, and volunteer (total n = 80 capsules). Volunteer 2 was included as a contributor to the DNA profiles generated from 100% of samples handled by them within the semi-realistic scenario, whereas the other volunteer could be included as a contributor in 65% of samples. For the realistic scenario, profiles could be generated with the inclusion of both volunteers as profile contributors in 15% of samples and from just one of the volunteers in a further 50% of samples (therefore in total, either both or one of the volunteers were detected in 65% of realistic samples). Surprisingly, it was not necessarily the case that the last person to handle the capsule was the major or only contributor. The potential variability in the DNA quantities that could be deposited onto the capsules of genuine illicit drugs is high and would vary on a case-by-case basis. Nevertheless, this study has indicated that in realistic scenarios where two people are involved in the later stages of illicit drug capsule preparation, that either one or both individuals may be identified, potentially opening new investigative leads for law enforcement agencies as well as offering new information for intelligence-led policing., (Crown Copyright © 2022.

Lymphogranuloma venereum (LGV), the invasive infection of the sexually transmissible infection (STI) Chlamydia trachomatis , is caused by strains from the LGV biovar, most commonly represented by ompA -genotypes L2b and L2. We investigated the diversity in LGV samples across an international collection over seven years using typing and genome sequencing. LGV-positive samples ( n =321) from eight countries collected between 2011 and 2017 (Spain n =97, Netherlands n =67, Switzerland n =64, Australia n =53, Sweden n =37, Hungary n =31, Czechia n =30, Slovenia n =10) were genotyped for pmpH and ompA variants. All were found to contain the 9 bp insertion in the pmpH gene, previously associated with ompA -genotype L2b. However, analysis of the ompA gene shows ompA -genotype L2b ( n =83), ompA -genotype L2 ( n =180) and several variants of these ( n =52; 12 variant types), as well as other/mixed ompA -genotypes ( n =6). To elucidate the genomic diversity, whole genome sequencing (WGS) was performed from selected samples using SureSelect target enrichment, resulting in 42 genomes, covering a diversity of ompA -genotypes and representing most of the countries sampled. A phylogeny of these data clearly shows that these ompA -genotypes derive from an ompA -genotype L2b ancestor, carrying up to eight SNPs per isolate. SNPs within ompA are overrepresented among genomic changes in these samples, each of which results in an amino acid change in the variable domains of OmpA (major outer membrane protein, MOMP). A reversion to ompA -genotype L2 with the L2b genomic backbone is commonly seen. The wide diversity of ompA -genotypes found in these recent LGV samples indicates that this gene is under immunological selection. Our results suggest that the ompA -genotype L2b genomic backbone is the dominant strain circulating and evolving particularly in men who have sex with men (MSM) populations.

Background: The clinical onset of borderline personality disorder (BPD) usually occurs in young people (aged 12-25 years) and commonly leads to difficulty achieving and maintaining vocational (education and/or employment) engagement. While current psychosocial interventions lead to improvements in psychopathology, they have little effect upon functioning. Individual Placement and Support (IPS) is a client-driven model that assists individuals with severe mental illness to engage with education and/or employment appropriate to their personal goals, and that provides ongoing support to maintain this engagement. The objective of the INdividual Vocational and Educational Support Trial (INVEST) is to evaluate the effectiveness of adding IPS to an evidence-based early intervention programme for BPD, with the aim of improving vocational outcomes., Methods/design: INVEST is a single-blind, parallel-groups, randomised controlled trial (RCT). The randomisation is stratified by gender and age and uses random permuted blocks. The interventions are 39 weeks of either IPS, or 'usual vocational services' (UVS). Participants will comprise 108 help-seeking young people (aged 15-25 years) with three or more DSM-5 BPD features and a desire to study or work, recruited from the Helping Young People Early (HYPE) early intervention programme for BPD at Orygen, in Melbourne, Australia. All participants will receive the HYPE intervention. After baseline assessment, staff who are blind to the intervention group allocation will conduct assessments at 13, 26, 39 and 52 weeks. At the 52-week primary endpoint, the primary outcome is the number of days in mainstream education/employment since baseline. Secondary outcomes include the cost-effectiveness of the intervention, quality of life, and BPD severity., Discussion: Current treatments for BPD have little impact on vocational outcomes and enduring functional impairment is prevalent among this patient group. IPS is a targeted functional intervention, which has proven effective in improving vocational outcomes for adults and young people with psychotic disorders. This trial will investigate whether IPS is effective for improving vocational (employment and educational) outcomes among young people with subthreshold or full-syndrome BPD., Trial Registration: Australian New Zealand Clinical Trials Registry, ID: ACTRN12619001220156 . 13 September 2019.

We investigate the ability of the 31 SNP loci in the Global AIMs Nano set to distinguish self-declared Australian Aboriginal individuals from European, Oceanic, African, Native American and East Asian populations. Human evolution suggests that Australian Aboriginal individuals came to Australia approximately 50 000 years ago, during the time it made up part of Sahul. Since then the colonisation of Australia by Europeans has meant significant admixture within the Australian Aboriginal population. These two events present themselves in our study with the Aboriginal population creating a continuous genetic cline between the Oceanic and European groups. We also assigned the Aboriginal individuals into their traditional regional groups to determine whether there was any ability to distinguish these from each other. We found similar results to studies using other markers, namely that the more remote regions (that have been less affected by admixture) diverged from the rest. Overall, we found the ability of the GNano system to differentiate self-declared Australian Aboriginal individuals was reasonable but had limitations that need to be recognised if these assignments are applied to unknown individuals., (Copyright © 2019 Elsevier B.V.

Background: Most mental illness is managed in general practice rather than specialist psychiatric settings. Management of mental illness in general practice is advocated as being less stigmatizing than psychiatric settings. Thus, other patients' discomfort with sharing the waiting room with the mentally ill may be problematic., Objectives: To examine prevalence and associations of discomfort of general practice waiting room patients with fellow patients with mental illness and the implications for practices of these attitudes. We sought attitudes reflecting social distance, a core element of stigmatization., Methods: A cross-sectional waiting room questionnaire-based study in 15 Australian general practices. Outcome measures were discomfort sharing a waiting room with patients with mental illness, likelihood of changing GP practice if that practice provided specialized care for patients with mental illness, and the perception that general practice is a setting where patients with mental illness should be treated., Results: Of 1134 participants (response rate 78.5%), 29.7% and 12.2%, respectively, reported they would be uncomfortable sharing a waiting room with a patient with schizophrenia or severe depression/anxiety. Only 29.9% and 48.8%, respectively, felt that general practice was an appropriate location for treatment of schizophrenia or severe depression/anxiety. Ten per cent would change their current practice if it provided specialized care for mentally ill patients., Conclusions: This desire of general practice patients for social distance from fellow patients with mental illness may have implications for both the GPs with a particular interest in mental disorders and the care-seeking and access to care of patients with mental illness.

Y-chromosome specific STR profiling is increasingly used in forensic casework. However, the strong geographic clustering of Y haplogroups can lead to large differences in Y-STR haplotype frequencies between different ethnicities, which may have an impact on database composition in admixed populations. Aboriginal people have inhabited Australia for over 40,000 years and until ∼300 years ago they lived in almost complete isolation. Since the late 18th century Australia has experienced massive immigration, mainly from Europe, although in recent times from more widespread origins. This colonisation resulted in highly asymmetrical admixture between the immigrants and the indigenes. A State jurisdiction within Australia has created an Aboriginal Y-STR database in which assignment of ethnicity was by self-declaration. This criterion means that some males who identify culturally as members of a particular ethnic group may have a Y haplogroup characteristic of another ethnic group, as a result of admixture in their paternal line. As this may be frequent in Australia, an examination of the extent of genetic admixture within the database was performed. A Y haplogroup predictor program was first used to identify Y haplotypes that could be assigned to a European haplogroup. Of the 757 males (589 unique haplotypes), 445 (58.8%) were identified as European (354 haplotypes). The 312 non-assigned males (235 haplotypes) were then typed, in a hierarchical fashion, with a Y-SNP panel that detected the major Y haplogroups, C-S, as well as the Aboriginal subgroup of C, C4. Among these 96 males were found to have non-Aboriginal haplogroups. In total, ∼70% of Y chromosomes in the Aboriginal database could be classed as non-indigenous, with only 169 (129 unique haplotypes) or 22% of the total being associated with haplogroups denoting Aboriginal ancestry, C4 and K* or more correctly K(xL,M,N,O,P,Q,R,S). The relative frequencies of these indigenous haplogroups in South Australia (S.A.) were significantly different to those seen in samples from the Northern Territory and Western Australia. In S.A., K* (∼60%) has a much higher frequency than C4 (∼40%), and the subgroup of C4, C4(DYS390.1del), comprised only 17%. Clearly admixture in the paternal line is at high levels among males who identify themselves as Australian Aboriginals and this knowledge may have implications for the compilation and use of Y-STR databases in frequency estimates., (Copyright © 2012 Elsevier Ireland Ltd.

The mucosal cytokine response of healthy humans to parasitic helminths has never been reported. We investigated the systemic and mucosal cytokine responses to hookworm infection in experimentally infected, previously hookworm naive individuals from non-endemic areas. We collected both peripheral blood and duodenal biopsies to assess the systemic immune response, as well as the response at the site of adult worm establishment. Our results show that experimental hookworm infection leads to a strong systemic and mucosal Th2 (IL-4, IL-5, IL-9 and IL-13) and regulatory (IL-10 and TGF-β) response, with some evidence of a Th1 (IFN-γ and IL-2) response. Despite upregulation after patency of both IL-15 and ALDH1A2, a known Th17-inducing combination in inflammatory diseases, we saw no evidence of a Th17 (IL-17) response. Moreover, we observed strong suppression of mucosal IL-23 and upregulation of IL-22 during established hookworm infection, suggesting a potential mechanism by which Th17 responses are suppressed, and highlighting the potential that hookworms and their secreted proteins offer as therapeutics for human inflammatory diseases.

Objective: To describe the longer-term clinical and functional outcome of a large, epidemiologic representative cohort of individuals experiencing a first episode of psychosis., Method: A naturalistic, prospective follow-up of an epidemiologic sample of 723 consecutive first-episode psychosis patients, followed between January 1998 and April 2005, at a median of 7.4 years after initial presentation to the Early Psychosis Prevention and Intervention Centre (EPPIC) in Melbourne, Australia. EPPIC is a frontline public mental health early psychosis program, servicing a geographically defined catchment area with a population of about 800,000 people. The main outcome measures included the Brief Psychiatric Rating Scale, the Schedule for the Assessment of Negative Symptoms, the Beck Depression Inventory, the Global Assessment of Functioning Scale, the Social and Occupational Functioning Assessment Scale, the Quality of Life Scale, and the remission criteria developed by the Remission in Schizophrenia Working Group., Results: Follow-up information was collected on up to 90.0% (n = 651) of the baseline cohort of 723 participants, with 66.9% (n = 484) interviewed. In the last 2 years, 57% of individuals with schizophrenia/schizophreniform, 54% with schizoaffective disorder, 62% with affective psychosis, and 68% with other psychotic disorders reported some paid employment. Depending upon the criteria applied, symptomatic remission at follow-up was observed in 37%-59% of the cohort. Social/vocational recovery was observed in 31% of the cohort. Approximately a quarter achieved both symptomatic remission and social/vocational recovery., Conclusion: The relatively positive outcomes are consistent with a beneficial effect of specialized early intervention programs; however it is premature to draw firm conclusions. There was no control group and there are many differences between the relevant comparison studies and the present one. Although difficult to conduct, large scale controlled health services research trials are required to definitively determine the impact and optimal duration of specialized early psychosis programs., (2010 Physicians Postgraduate Press, Inc.)

Objective: We investigated illness beliefs of recently hospitalized patients with coronary artery disease (CAD) and the prospective association between these beliefs and adherence to secondary prevention behaviors. Causal attributions of CAD and their concordance with actual patient risk profiles were also examined., Method: A prospective study of 193 patients was conducted. Data were collected by self-report and from medical records at 3, 6, and 9 months after discharge. Baseline depression was assessed by structured clinical interview. The association between illness beliefs and adherence was tested with hierarchical linear regression controlling for clinical and demographic confounders., Results: Most participants perceived high personal and treatment control and believed CAD to be chronic in duration with severe consequences. A relatively low number of symptoms were endorsed as being part of CAD. Heredity was considered the single most important and most commonly perceived cause of CAD. Smoking, alcohol, emotional state, and heredity were significantly more likely to be endorsed as causal factors by respondents with these risk profiles. In multivariate analysis, illness beliefs contributed an additional 6% of the total variance explained by the model (p = .02). Perceptions of more serious consequences predicted better adherence (p = .03). Social desirability was the best single predictor of adherence., Conclusion: Patient perceptions of risk factors were largely consistent with actual risk factors. Despite modest effect sizes, illness beliefs do contribute to our understanding of adherence to secondary prevention behavior. Interventions aimed at modifying these beliefs, particularly those related to the consequences of CAD, may improve patient outcomes.

Unlabelled: Young people with borderline personality disorder (BPD) commonly seek help but often go unrecognized. Screening offers a means of identifying individuals for more detailed assessment for early intervention and for research., Aims: This study compared the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD), Borderline Personality Questionnaire (BPQ), the BPD items from the International Personality Disorder Examination Screening Questionnaire and the BPD items from the Structured Clinical Interview for DSM-IV Axis II disorders (SCID-II) Personality Questionnaire., Method: 101 outpatient youth (aged 15-25 years) completed the screening measures and were interviewed, blind to screening status, with the SCID-II BPD module. The screening measures were readministered two weeks later to assess test-retest reliability., Results: All four instruments performed similarly but the BPQ had the best mix of characteristics, with moderate sensitivity (0.68), the highest specificity (0.90), high negative predictive value (0.91) and moderate positive predictive value (0.65). Compared to the other three instruments, the BPQ had the highest overall diagnostic accuracy (0.85), a substantially higher kappa (0.57) with the criterion diagnosis, the highest test-retest reliability (ICC = 0.92) and the highest internal consistency (alpha = 0.92). The only clear difference to emerge in the Receiver Operator Curve (ROC) analysis was that the BPQ significantly outperformed the MSI (p = 0.05)., Conclusion: Screening for BPD in out-patient youth is feasible but is not a replacement for clinical diagnosis.

Studies have documented poor functioning and higher rates of negative life events in association with personality disorders (PDs), in particular with borderline personality disorder (BPD). The current study investigated the impact of recent life events, daily hassles and uplifts on psychosocial functioning in patients with PDs, while extending previous research by examining the role of perceived coping effectiveness and perceived stress of recent life events. Ninety-seven participants (Axis I group, N = 30; BPD group, N = 23; Other PD group, N = 44) completed measures of functioning, recent life events, daily hassles and uplifts. Results indicated that the BPD group reported the poorest levels of functioning, especially interpersonal functioning. The BPD group also reported more negative life events, particularly in the interpersonal relationships, personal health, crime, and financial domains. The BPD group experienced less uplifts, more hassles and found employment circumstances particularly stressful and difficult to cope with. Intensity of hassles was a predictor of functioning independent of a BPD diagnosis. A greater frequency of life events was closely associated with a non-BPD diagnosis in predicting a decrease in psychosocial functioning.

Background: The aims of this study were threefold. First, to ascertain whether personality disorder (PD) was a significant predictor of disability (as measured in a variety of ways) over and above that contributed by Axis I mental disorders and physical conditions. Second, whether the number of PD diagnoses given to an individual resulted in increasing severity of disability, and third, whether PD was a significant predictor of health and mental health consultations with GPs, psychiatrists, and psychologists, respectively, over the last 12 months., Method: Data were obtained from the National Survey of Mental Health and Wellbeing, conducted between May and August 1997. A stratified random sample of households was generated, from which all those aged 18 and over were considered potential interviewees. There were 10,641 respondents to the survey, and this represented a response rate of 78 %. Each interviewee was asked questions indexing specific ICD-10 PD criteria., Results: Five measures of disability were examined. It was found that PD was a significant predictor of disability once Axis I and physical conditions were taken into account for four of the five disability measures. For three of the dichotomously-scored disability measures, odds ratios ranged from 1.88 to 6.32 for PD, whilst for the dimensionally-scored Mental Summary Subscale of the SF-12, a beta weight of -0.17 was recorded for PD. As regards number of PDs having a quasi-linear relationship to disability, there was some indication of this on the SF-12 Mental Summary Subscale and the two role functioning measures, and less so on the other two measures. As regards mental consultations, PD was a predictor of visits to GPs, psychiatrists and psychologists, over and above Axis I disorders and physical conditions., Conclusion: The study reports findings from a nationwide survey conducted within Australia and as such the data are less influenced by the selection and setting bias inherent in other germane studies. However, it does support previous findings that PD is a significant predictor of disability and mental health consultations independent of Axis I disorders and physical conditions.

The aging of the U.S. population presents challenges in financing care and meeting the health and long-term care needs of older Americans. Women, who constitute a majority of the older adult population and a disproportionate share of those with low incomes, chronic conditions and long-term care needs, have much at stake in the future direction of health programs for aging Americans. This paper examines the status of older women in 12 industrialized nations to assess how the U.S. compares to other countries in terms of its aging female population. We find that women across the 12 industrialized countries have a longer life expectancy than men at ages 65 and 80, underscoring the universality of aging as a "women's issue". With respect to age composition, the U.S. lags behind many industrialized nations in the share of its elderly female population; by 2030, the proportion of women aged 65 and older, and 80 and older, will be lower in the U.S. than in any of the industrialized nations compared in this paper. Against this backdrop, the paper examines the characteristics of older adult women in the U.S., considers the role of Medicare in meeting the needs of aging women, and identifies gaps in coverage, primarily prescription drug and long-term care, that disproportionately affect older women. The paper concludes by considering how other nations provide and finance prescription drug and long-term care services for older adults, suggesting useful models for the U.S. to consider as it struggles to meet the demands of its aging population.

Based on a program developed for the Papago Indians of Arizona, five Australian Aborigines were trained as Behavioral Health workers, to deliver mental health services to their group. The problems of the Aborigines are very similar to those of the Indians. The training consisted of developing basic skills in interviewing, case indentification and several methods of intervention, including crisis intervention, family and alcoholism counselling. A mental health clinic was developed for the Aboriginal community for health services and training. Community projects and field trips were part of the training, as was report writing, record keeping and presentations to professional groups.
