Accessible summary Borderline personality disorder (BPD) is a complex and challenging mental health condition for the person and service providers who support them., This paper reports on the results of a survey of 153 people with a diagnosis of BPD about their experiences of attempting to receive support in managing this mental health condition. It provides their perceptions of a range of experiences not reported in the existing literature, including general practitioner roles, urban and rural differences, public and private hospital differences, and comparison of usefulness of support across multiple support types., People with a diagnosis of BPD continue to experience significant discrimination when attempting to get their needs met within both public and private health services. Further education for nurses and other health professionals is indicated to address pervasive negative attitudes towards people with a diagnosis of BPD., Abstract There is limited understanding of the experience of seeking and receiving treatment and care by people with a diagnosis of borderline personality disorder ( BPD), their perceptions of barriers to care and the quality of services they receive. This study aimed to explore these experiences from the perspective of Australians with this diagnosis. An invitation to participate in an online survey was distributed across multiple consumer and carer organizations and mental health services, by the Private Mental Health Consumer Carer Network ( Australia) in 2011. Responses from 153 people with a diagnosis of BPD showed that they experience significant challenges and discrimination when attempting to get their needs met within both public and private health services, including general practice. Seeking help from hospital emergency departments during crises was particularly challenging. Metropolitan and rural differences, and gender differences, were also apparent. Community supports were perceived as inadequate to meet their needs. This study provides data on a range of experiences not reported in existing literature, including general practitioner roles, urban and rural differences, public and private hospital differences, and comparison of usefulness of support across multiple support types. Its findings can help inform better training for health professionals and better care for this population. [ABSTRACT FROM AUTHOR]

Accessible summary Borderline personality disorder (BPD) is a complex and challenging mental health condition for the person and family carers who support them., This paper reports on the results of a survey of 121 family carers of people diagnosed with BPD about their experiences of being carers, their attempts to seek help for the person diagnosed with BPD and their own carer needs. It provides the first detailed account across these domains., Family carers of people diagnosed with BPD experience significant exclusion and discrimination when attempting to interact with generalist health and mental health services. Further education for all health professionals is indicated, particularly general practitioners who likely come into contact with BPD carers. All health professionals need to improve their skills and attitudes in working with people diagnosed with BPD, and also their skills and attitudes in working with BPD carers. Carers of people diagnosed with BPD may need specialist carer support that addresses their distinct information, education and support needs., Abstract There is limited understanding of the experience of family carers of people diagnosed with borderline personality disorder ( BPD). This study aimed to explore their experiences of being carers, their attempts to seek help for the person diagnosed with BPD and their own carer needs. An invitation to participate in an online survey was distributed to carers across multiple consumer and carer organizations and mental health services, by the Private Mental Health Consumer Carer Network ( Australia) in 2011. Responses from 121 carers showed that they experience significant challenges and discrimination when attempting to engage with and seek support from health services. Comparison with consumers' experiences (reported elsewhere) showed that these carers have a clear understanding of the discrimination faced by people with this diagnosis, largely because they also experience exclusion and discrimination. Community carer support services were perceived as inadequate. General practitioners were an important source of support; however, they and other service providers need more education and training to support attitudinal change to address discrimination, recognize carers' needs and provide more effective support. This study provides the first detailed account of BPD carers' experiences across a broad range of support needs and interactions with community support and health services. [ABSTRACT FROM AUTHOR]

An obituary for Roderick Pitt Meagher, former Justice of the Supreme Court of New South Wales and Appeals Court, is presented.

Environmental offsetting has been developed as a mechanism to facilitate the benefits from economic development while avoiding or minimizing environmental harm. This is achieved by compensating for environmental impacts at one location by generating equivalent environmental improvements elsewhere. However, experience with biodiversity and carbon offsetting indicates it can be difficult to ensure the integrity of offsets. Under recent legislation in the catchments of the Great Barrier Reef (GBR), Australia, it is mandatory for water quality emissions from new or expanded point source development to be offset by reducing pollution elsewhere, frequently through reducing non-point source pollution (NPSP). Therefore, informed by experience with biodiversity and carbon offsetting, we summarised sources of uncertainty in NPSP reduction that would influence water quality offset integrity; estimated the maximum potential demand for water quality offsets from sewage treatment plants, the largest point source emitter of total nitrogen (TN) in the GBR catchments, between 2018 and 2050; and discussed the implications of both on the ability of offsetting to counterbalance the impact of economic development in catchments where nitrogen loads have a large influence on the health of important GBR ecosystems. The catchments surrounding the population centres of Cairns and Mackay had both a potentially high future demand for nitrogen water quality offsets and nitrogen loads with a strong influence on the health of the GBR. Consequently, any low integrity water quality offsets in these catchments could jeopardise progress toward the water quality improvements needed to ensure the continued health of the GBR. Water quality offsetting has numerous strengths as a policy instrument however substantial uncertainties remain related to environmental outcomes. Until further research can reduce these uncertainties, water quality offsets that are implemented near increased point source emissions and have a high certainty of effectiveness may provide a balance between scientific rigour and policy workability., 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 Elsevier B.V.

The traditional model of centralisation of care, whilst having many advantages, also requires adaptation and upscaling to meet the requirements of both regional areas and the increasing urban sprawl. However, to ensure comparable outcomes with current major centres, this transition, when required, must be delivered in a safe and effective manner. Our project, which utilised the British Association of Oral and Maxillofacial Surgeons (BAOMS) recently published outcome data from the Quality and Outcomes in Oral and Maxillofacial Surgery (QOMS) project to benchmark data prospectively collected from a small-volume, emerging centre in Northern Queensland, was the first of its kind in terms of validation studies. As expected, the small volume of our centre impacted the ability to derive powerful statistical models and comparators, an intrinsic limitation for small-volume centres whilst they are developing services. However, during this evolution project, the use of comparison metrics allowed for the detection of alert and alarm levels, which are invaluable to ensure patient safety and quality of outcome.Our paper demonstrated that, irrespective of size or volume, the utilisation of quality assurance metrics (national or international) provides for the safe and transparent upscaling of head and neck services in emerging, regional, and small-volume centres., (Copyright © 2024.

The Australian Partnership for Preparedness Research on InfectiouS disease Emergencies (APPRISE) has developed a virtual biobank to support infectious disease research in Australia. The virtual biobank (https://apprise.biogrid.org.au) integrates access to existing distributed infectious disease biospecimen collections comprising multiple specimen types, including plasma, serum, and peripheral blood mononuclear cells. Through the development of a common data model, multiple collections can be searched simultaneously via a secure web portal. The portal enhances the visibility and searchability of existing collections within their current governance and custodianship arrangements. The portal is easily scalable for integration of additional collections.

Background: Many Australians experience mental health challenges, but only a third access face-to-face psychological services, due to multiple barriers including long waitlists. Additional strategies to prevent or help people de-escalate distress at an early stage are needed. Web-based mental health interventions are becoming increasingly acceptable to consumers and referring General Practitioners (GPs), but most are designed for specific disorders/populations. This study explores consumers' and health professionals' preferences and recommendations for the design of a transdiagnostic, Acceptance and Commitment Therapy (ACT)-based, online intervention for Australian adults., Methods: Thirty-five people (consumers, carers, GPs, mental health professionals) participated in one or more co-design stages. Stage 1: semi-structured interviews to establish what is wanted from such websites (n = 22). Stage 2: feedback emailed on branding options (n = 20). Stage 3: feedback provided via Zoom or an online survey after testing a website prototype (n = 19). Data were analysed using Thematic Framework Analysis and descriptive statistics., Results: Stage 1 highlighted nine key design principles (plus 25 subthemes) that participants emphasised as important to ensure the website would have broad appeal and meet their needs: (1) user choice is valued highly; (2) ACT-based content is acceptable as it is focused on helping people be proactive and 'get unstuck'; (3) non-pathologising, direct, empowering, lay language is endorsed; (4) a positive look and feel is appreciated; (5) images and videos are important to break up text and maintain engagement; (6) short text messages to aid engagement are valued; (7) provision of tailored psychoeducation for highly distressed and suicidal users is endorsed; (8) personal and proactive brand name is preferred (icanactnow); (9) diverse marketing and training activities are recommended. In Stage 2, icanactnow branding preferences were elicited (simplicity, colours to represent growth and a call to action). Stage 3 resulted in the inclusion of a safety plan template and a tailored entry portal for people referred to icanactnow by health professionals. High levels of satisfaction with the prototype were reported., Conclusions: These findings informed icanactnow and provide insights for the development of other online mental health interventions, in ways that appeal to both consumers and professionals recommending them., (© 2023.

In 2014, UNAIDS outlined the 90-90-90 treatment targets. The "fourth 90" reflects the need to focus on optimising quality of life (HRQoL) in people living with HIV. Using a sample of non-heterosexual males in Melbourne, Australia, we aimed to assess HRQoL differences between HIV-positive and HIV-negative individuals, and identify factors that predict HRQoL both at baseline and after three years of follow up. Clinical information and patient-reported outcomes incorporating the Assessing Quality of Life-6D scale were collected at baseline and at three years. Sixty-two HIV-positive cases (antiretroviral therapy naïve at baseline) and 48 controls were enrolled. Results were compared between cases and controls at baseline, three-year follow-up, and between timepoints. HRQoL was significantly lower in cases compared to controls (83.5 (IQR 77.2-88.6) vs 87.3 (IQR 82.1-91.8), p  = 0.022) at baseline, with increased depression and anxiety associated with reduced HRQoL in multivariate analysis. Mental health in cases improved between timepoints (75.0 (IQR 56.3-81.3) to 81.3 (IQR 62.5-81.3), p  = 0.0428). No differences between the HRQoL of cases and controls were observed at three years. Increased mental health support may be required at commencement of antiretroviral therapy to enable similar levels of HRQoL between HIV-positive and HIV-negative individuals to be achieved.

Lymphocytic choriomeningitis virus (LCMV) is a zoonotic virus that can cause clinically significant illnesses in humans. Although cases of LCMV infection are well described globally, and there is evidence that the virus is present in Australian rodent populations, there has been only one case of domestically acquired LCMV infection published previously. Here, we describe a cluster of LCMV infections in South-East Queensland identified in early 2021, and the diagnostic testing processes implemented. This identifies LCMV as an under-recognised human pathogen in Australia., (© 2022 Royal Australasian College of Physicians.)

On the 26th of November 2021, the World Health Organization (WHO) designated the newly detected B.1.1.529 lineage of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) the Omicron Variant of Concern (VOC). The genome of the Omicron VOC contains more than 50 mutations, many of which have been associated with increased transmissibility, differing disease severity, and potential to evade immune responses developed for previous VOCs such as Alpha and Delta. In the days since the designation of B.1.1.529 as a VOC, infections with the lineage have been reported in countries around the globe and many countries have implemented travel restrictions and increased border controls in response. We putatively detected the Omicron variant in an aircraft wastewater sample from a flight arriving to Darwin, Australia from Johannesburg, South Africa on the 25th of November 2021 via positive results on the CDC N1, CDC N2, and del(69-70) RT-qPCR assays per guidance from the WHO. The Australian Northern Territory Health Department detected one passenger onboard the flight who was infected with SARS-CoV-2, which was determined to be the Omicron VOC by sequencing of a nasopharyngeal swab sample. Subsequent sequencing of the aircraft wastewater sample using the ARTIC V3 protocol with Nanopore and ATOPlex confirmed the presence of the Omicron variant with a consensus genome that clustered with the B.1.1.529 BA.1 sub-lineage. Our detection and confirmation of a single onboard Omicron infection via aircraft wastewater further bolsters the important role that aircraft wastewater can play as an independent and unintrusive surveillance point for infectious diseases, particularly coronavirus disease 2019., 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 The Authors.

There is a large burden of norovirus disease in child-care centers in Australia and around the world. Despite the ubiquity of norovirus outbreaks in child-care centers, little is known about the extent of this burden within the child-care center and the surrounding household clusters. Therefore, we performed an in-depth analysis of a gastroenteritis outbreak to examine the patterns of transmissions, household attack rates and the basic reproduction number (R0) for Norovirus in a child-care facility. We used data from parental interviews of suspected cases sent home with gastroenteritis at a child-care center between 24th of August and 18th of September 2020. A total of 52 persons in 19 household clusters were symptomatic in this outbreak investigation. Of all transmissions, 23 (46.9%) occurred in the child-care center, the rest occurring in households. We found a household attack rate of 36.5% (95% CI 27.3, 47.1%). Serial intervals were estimated as mean 2.5 ± SD1.45 days. The R0, using time-dependent methods during the growth phase of the outbreak (days 2 to 8) was 2.4 (95% CI 1.50, 3.50). The count of affected persons of a child-care center norovirus outbreak is approximately double the count of the total symptomatic staff and attending children. In the study setting, each symptomatic child-care attendee likely infected one other child-care attendee or staff and just over one household contact on average., Competing Interests: The authors have declared that no competing interests exist.

Mental health issues are a severe global concern with significant personal, social, and economic consequences and costs. This paper reports results of an online survey disseminated across the Australian community investigating why people with mental health issues choose particular mental health services over others, what causes them to disengage from services, and what factors and qualities of services are important to consumers to support their continued engagement or re-engagement with mental health services. The importance of GPs was evident, given their key role in providing mental healthcare, especially to those referred to as "the missing middle"-consumers with mental health issues who fall through the gaps in care in other parts of the healthcare system. The study found that many respondents chose to engage with mental healthcare providers primarily due to accessibility and affordability, but also because of the relational qualities that they displayed as part of delivering care. These qualities fostered consumers' sense of trust, feeling listened to, and not being stigmatized as part of help seeking and having their mental health needs met. Implications for education and practice are offered.

WHAT IS KNOWN ON THE SUBJECT?: Internationally, stigma towards people with mental illness has reduced due to greater understanding, education and advocacy in the community, and more focus on recovery-oriented care within practice guidelines. However, many people with a diagnosis of BPD continue to experience stigma and difficulty accessing health services. Contributing factors include lack of understanding of BPD and effective management by health professionals, stigma from the general population and within healthcare services, and financial and geographical barriers. Mental health nurses comprise a large part of the healthcare workforce responsible for the day-to-day care of people diagnosed with BPD. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE: This paper investigates how Australian consumer perspectives on BPD management have changed over time. Comments from a large survey, delivered to consumers in 2011 (N = 153) and 2017 (N = 424), were analysed for common themes. Themes were broadly related to NHMRC BPD Guidelines sections released in 2013. These data sets therefore present an opportunity to evaluate changes in consumer perspectives pre- and post-Guideline release. Although no direct causal relationship can be drawn, analysing these changes can potentially assist with understanding the impact of the Guidelines in practice. No such analysis of the Australian Guidelines has been conducted to date in the existing literature. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Many people diagnosed with BPD continue to experience stigma, barriers to treatment and difficulty accessing appropriate services. Widespread practical implementation of the Guidelines was not apparent; however, improved general awareness and understanding of BPD from consumers and health professionals were evident. Improved education and practice across each and all aspects of the Guidelines are indicated. The Guidelines need review to ensure they are in-line with current evidence-based practice, as well as effective health professional education, support and funding to embed the revised Guidelines into practice. ABSTRACT: Introduction Internationally, many individuals diagnosed with BPD continue to experience stigma within health care and are more likely to be viewed as manipulative and evoke negative responses from clinicians, compared with other mental health consumers. Aim/Question To understand Australian consumer perspectives regarding BPD management, and how these have changed between 2011 and 2017. To comment on how NHMRC BPD Guidelines, released 2013, are faring in practice. Method Individuals who identified a BPD diagnosis completed a 75-question survey, delivered online Australia-wide, in 2011 (N = 153) and 2017 (N = 424), providing comparative data sets to evaluate changes in consumer perspective on BPD management. Results Many people diagnosed with BPD experience difficulties when seeking help, stigma within health services and barriers to treatment. Improved general awareness, communication and understanding of BPD from consumers and health professionals were evident. Discussion Consumers demonstrated increased BPD-literacy and help-seeking behaviours in 2017, providing opportunity for health professionals to build stronger therapeutic relationships. Widespread practical implementation of the Guidelines does not appear to have been achieved. More health professional education, updated Guidelines, funding and strategies to embed these Guidelines into practice are needed. Implications for Practice Mental health nurses regularly provide care to people diagnosed with BPD; with practical education and support, they and other health professionals can improve their confidence in practice and provide better quality care to consumers., (© 2020 The Authors.

Ambitious World Health Organization targets for disease elimination require monitoring of epidemics using routine health data in settings of decreasing and low incidence. We evaluated 2 methods commonly applied to routine testing results to estimate incidence rates that assume a uniform probability of infection between consecutive negative and positive tests based on 1) the midpoint of this interval and 2) a randomly selected point in this interval. We compared these with an approximation of the Poisson binomial distribution, which assigns partial incidence to time periods based on the uniform probability of occurrence in these intervals. We assessed bias, variance, and convergence of estimates using simulations of Weibull-distributed failure times with systematically varied baseline incidence and varying trend. We considered results for quarterly, half-yearly, and yearly incidence estimation frequencies. We applied the methods to assess human immunodeficiency virus (HIV) incidence in HIV-negative patients from the Treatment With Antiretrovirals and Their Impact on Positive and Negative Men (TAIPAN) Study, an Australian study of HIV incidence in men who have sex with men, between 2012 and 2018. The Poisson binomial method had reduced bias and variance at low levels of incidence and for increased estimation frequency, with increased consistency of estimation. Application of methods to real-world assessment of HIV incidence found decreased variance in Poisson binomial model estimates, with observed incidence declining to levels where simulation results had indicated bias in midpoint and random-point methods., (© The Author(s) 2021.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiological agent of COVID-19, is a readily transmissible and potentially deadly pathogen which is currently re-defining human susceptibility to pandemic viruses in the modern world. The recent emergence of several genetically distinct descendants known as variants of concern (VOCs) is further challenging public health disease management, due to increased rates of virus transmission and potential constraints on vaccine effectiveness. We report the isolation of SARS-CoV-2 VOCs imported into Australia belonging to the B.1.351 lineage, first described in the Republic of South Africa (RSA), and the B.1.1.7 lineage originally reported in the United Kingdom, and directly compare the replication kinetics of these two VOCs in Vero E6 cells. In this analysis, we also investigated a B.1.1.7 VOC (QLD1516/2021) carrying a 7-nucleotide deletion in the open reading frame 7a (ORF7a) gene, likely truncating and rendering the ORF7a protein of this virus defective. We demonstrate that the replication of the B.1.351 VOC (QLD1520/2020) in Vero E6 cells can be detected earlier than the B.1.1.7 VOCs (QLD1516/2021 and QLD1517/2021), before peaking at 48 h post infection (p.i.), with significantly higher levels of virus progeny. Whilst replication of the ORF7a defective isolate QLD1516/2021 was delayed longer than the other viruses, slightly more viral progeny was produced by the mutant compared to the unmutated isolate QLD1517/2021 at 72 h p.i. Collectively, these findings contribute to our understanding of SARS-CoV-2 replication and evolutionary dynamics, which have important implications in the development of future vaccination, antiviral therapies, and epidemiological control strategies for COVID-19.

Background: On 31 December 2019, the World Health Organization recognised clusters of pneumonia-like cases due to a novel coronavirus disease (COVID-19). COVID-19 became a pandemic 71 days later., Aim: To report the clinical and epidemiological features, laboratory data and outcomes of the first group of 11 returned travellers with COVID-19 in Australia., Methods: This is a retrospective, multi-centre case series. All patients with confirmed COVID-19 infection were admitted to tertiary referral hospitals in New South Wales, Queensland, Victoria and South Australia., Results: The median age of the patient cohort was 42 years (interquartile range (IQR), 24-53 years) with six men and five women. Eight (72.7%) patients had returned from Wuhan, one from Shenzhen, one from Japan and one from Europe. Possible human-to-human transmission from close family contacts in gatherings overseas occurred in two cases. Symptoms on admission were fever, cough and sore throat (n = 9, 81.8%). Co-morbidities included hypertension (n = 3, 27.3%) and hypercholesterolaemia (n = 2, 18.2%). No patients developed severe acute respiratory distress nor required intensive care unit admission or mechanical ventilation. After a median hospital stay of 14.5 days (IQR, 6.75-21), all patients were discharged., Conclusions: This is a historical record of the first COVID-19 cases in Australia during the early biocontainment phase of the national response. These findings were invaluable for establishing early inpatient and outpatient COVID-19 models of care and informing the management of COVID-19 over time as the outbreak evolved. Future research should extend this Australian case series to examine global epidemiological variation of this novel infection., (© 2021 Royal Australasian College of Physicians.)

West Nile virus, Kunjin strain (WNV KUN ) is endemic in Northern Australia, but rarely causes clinical disease in humans and horses. Recently, WNV KUN genomic material was detected in cutaneous lesions of farmed saltwater crocodiles ( Crocodylus porosus ), but live virus could not be isolated, begging the question of the pathogenesis of these lesions. Crocodile hatchlings were experimentally infected with either 10 5 ( n = 10) or 10 4 ( n = 11) TCID 50 -doses of WNV KUN and each group co-housed with six uninfected hatchlings in a mosquito-free facility. Seven hatchlings were mock-infected and housed separately. Each crocodile was rotationally examined and blood-sampled every third day over a 3-week period. Eleven animals, including three crocodiles developing typical skin lesions, were culled and sampled 21 days post-infection (dpi). The remaining hatchlings were blood-sampled fortnightly until experimental endpoint 87 dpi. All hatchlings remained free of overt clinical disease, apart from skin lesions, throughout the experiment. Viremia was detected by qRT-PCR in infected animals during 2-17 dpi and in-contact animals 11-21 dpi, indicating horizontal mosquito-independent transmission. Detection of viral genome in tank-water as well as oral and cloacal swabs, collected on multiple days, suggests that shedding into pen-water and subsequent mucosal infection is the most likely route. All inoculated animals and some in-contact animals developed virus-neutralizing antibodies detectable from 17 dpi. Virus-neutralizing antibody titers continued to increase in exposed animals until the experimental endpoint, suggestive of persisting viral antigen. However, no viral antigen was detected by immunohistochemistry in any tissue sample, including from skin and intestine. While this study confirmed that infection of saltwater crocodiles with WNV KUN was associated with the formation of skin lesions, we were unable to elucidate the pathogenesis of these lesions or the nidus of viral persistence. Our results nevertheless suggest that prevention of WNV KUN infection and induction of skin lesions in farmed crocodiles may require management of both mosquito-borne and water-borne viral transmission in addition to vaccination strategies., Competing Interests: The authors declare no conflict of interest.

Background Recruitment of people to randomised trials of online interventions presents particular challenges and opportunities. The aim of this study was to evaluate factors associated with the recruitment of people with HIV (PWHIV) and their doctors to the HealthMap trial, a cluster randomised trial of an online self-management program., Methods: Recruitment involved a three-step process. Study sites were recruited, followed by doctors caring for PWHIV at study sites and finally PWHIV. Data were collected from study sites, doctors and patient participants. Factors associated with site enrolment and patient participant recruitment were investigated using regression models., Results: Thirteen study sites, 63 doctor participants and 728 patient participants were recruited to the study. Doctors having a prior relationship with the study investigators (odds ratio (OR) 13.3; 95% confidence interval (CI) 3.0, 58.7; P = 0.001) was positively associated with becoming a HealthMap site. Most patient participants successfully recruited to HealthMap (80%) had heard about the study from their HIV doctor. Patient enrolment was associated with the number of people with HIV receiving care at the site (β coefficient 0.10; 95% CI 0.04, 0.16; P = 0.004), but not with employing a clinic or research nurse to help recruit patients (β coefficient 55.9; 95% CI -2.55, 114.25; P = 0.06)., Conclusion: Despite substantial investment in online promotion, a previous relationship with doctors was important for doctor recruitment, and doctors themselves were the most important source of patient recruitment to the HealthMap trial. Clinic-based recruitment strategies remain a critical component of trial recruitment, despite expanding opportunities to engage with online communities.

Measles vaccines have been in use since the 1960s with excellent safety and effectiveness profiles. Limited data are available on detection of measles vaccine virus (MeVV) RNA in human subjects following vaccination. Available evidence suggests MeVV RNA can be identified up to 14 days after vaccination, with detection beyond this rare. In routine diagnostic testing, we used two real-time reverse transcription-polymerase chain reaction (RT-rPCR) assays targeting M and F genes to identify measles virus (MeV) and MeVV RNA. Confirmatory testing was performed with an N gene RT-rPCR, followed by sequence confirmation of RT-rPCR positives by semi-nested conventional RT-PCR assays targeting portions of the N, H, and L genes. We report detection and confirmation of MeVV RNA from the respiratory tract of 11 children between 100 and 800 days after most recent receipt of measles-containing vaccine. These novel findings emphasize the importance of genotyping all MeV detections and highlight the need for further work to assess whether persistent MeVV RNA represents viable virus and if transmission to close contacts can occur., Competing Interests: Jamie McMahon—no conflict; Ian M Mackay—no conflict; Stephen B Lambert—SBL is the current Chair of the National Measles and Rubella Elimination Working Party.

The prevalence of people seeking care for Borderline Personality Disorder (BPD) in primary care is four to five times higher than in the general population. Therefore, general practitioners (GPs) are important sources of assessment, diagnosis, treatment, and care for these patients, as well as important providers of early intervention and long-term management for mental health and associated comorbidities. A thematic analysis of two focus groups with 12 GPs in South Australia (in discussion with 10 academic, clinical, and lived experience stakeholders) highlighted many challenges faced by GPs providing care to patients with BPD. Major themes were: (1) Challenges Surrounding Diagnosis of BPD; (2) Comorbidities and Clinical Complexity; (3) Difficulties with Patient Behaviour and the GP⁻Patient Relationship; and (4) Finding and Navigating Systems for Support. Health service pathways for this high-risk/high-need patient group are dependent on the quality of care that GPs provide, which is dependent on GPs' capacity to identify and understand BPD. GPs also need to be supported sufficiently in order to develop the skills that are necessary to provide effective care for BPD patients. Systemic barriers and healthcare policy, to the extent that they dictate the organisation of primary care, are prominent structural factors obstructing GPs' attempts to address multiple comorbidities for patients with BPD. Several strategies are suggested to support GPs supporting patients with BPD.

Background: The continuing uncertainty about the silica-systemic sclerosis relationship led to the investigation of its role as a disease determinant in a large population-based study of systemic sclerosis., Aims: To compare the frequency, socioeconomic and educational status, age-specific prevalence and duration of occupational silica exposure in males with and without systemic sclerosis. To assess the temporal relationship between exposure and disease onset. To estimate disease latency. To compare disease characteristics between silica-exposed and non-silica-exposed male cases., Methods: The study was case-control in design. The exposure variable was occupational silica exposure as assessed by an occupational health officer blinded to case/control status and the outcome variable was systemic sclerosis. The employed instrument comprised either a standardised telephone questionnaire (interviewed cases and controls) or medical records (deceased or living-status-unknown cases)., Results: Sixty of 160 cases (37.5%) and 11 of 83 (13.3%) controls had occupational silica exposure (OR=3.93; 1.84-8.54). Comparison of data between 64 interviewed cases and all controls demonstrated initial occupational silica exposure occurring before age 40, comparable educational status but significantly different cumulative socioeconomic status with cases being over-represented in semi-skilled and unskilled occupations. Cross-sectional 'current' occupational data underestimated cumulative silica exposure by more than 50%. Silica exposure uniformly preceded onset of second disease symptoms and disease diagnosis. In most, it also preceded onset of first disease symptoms. Disease latency approximated two decades. No disease features distinguished silica-associated systemic sclerosis from idiopathic systemic sclerosis. The duration of silica exposure in the interviewed silica-exposed cases did not significantly exceed that of silica-exposed controls., Conclusions: Male systemic sclerosis displays socioeconomic dependence. Silica is a disease determinant in male systemic sclerosis, with disease features including a long latency and clinical characteristics indistinguishable from idiopathic disease. Cross-sectional 'current' occupational data underestimate cumulative occupational silica exposure.

Revised procedures for the post-mortem inspection of cattle and pigs at Australian abattoirs were developed as minimum national requirements. Comparative trials of current and revised procedures were conducted at 3 and 4 Australian abattoirs for pigs and cattle respectively. Residual pathological changes after inspection and removal of lesions from heads, carcases or viscera were recorded by an evaluation team with the data used to determine relative effectiveness. For cattle, there was no significant difference between current and revised procedures. Although it had been proposed to eliminate routine incision of cervical lymph nodes for pigs, it was found necessary to retain this procedure. The data also revealed a significant variation in detection of pathology between abattoirs for both species. Parasitic conditions accounted for the greatest proportion of undetected lesions in both species for both current and revised procedures. These comprised mainly fascioliasis in cattle and ascariasis in pigs. The former was associated with the study being conducted in eastern Australia. Chronic interstitial nephritis was also a common undetected lesion, reinforcing the need for intensified inspection of kidneys. However, such residual pathology was considered to be of only limited significance to human health. The revised procedures and findings are discussed in the context of animal and human health and of the importance of the meat industry to Australian exports. Some attention has been given to specific conditions likely to be affected by the proposals including tuberculosis, bovine cysticercosis, fascioliasis, porcine arthritis and salmonellosis. The role of meat inspection in monitoring for specific diseases is discussed.(ABSTRACT TRUNCATED AT 250 WORDS)
