Abstract ContextFeral pigs (Sus scrofa) are an increasing threat to agriculture and ecological communities globally. Although ground rooting is their most readily observable sign, feral pigs typically remain highly cryptic and their abundance and impacts are difficult to quantify. AimsThe aim of the present study was to evaluate the effect of current feral pig population management practices (trapping, baiting, no feral pig management) on feral pig abundance and digging impacts, using a BACI (before–after control–impact) experimental design at a landscape scale. MethodsA monitoring program was established to quantify both the abundance and digging impacts of feral pig populations within a temperate sclerophyll forest landscape using distance sampling. Transects were established across eight drinking water catchments where the whole catchment was the unit of replication for feral pig population management. Monitoring was carried out at 6-monthly intervals for 3 years, with no feral pig population management undertaken in the first year. In total, 367 feral pigs were trapped out of three catchments subject to trapping, and 26 were baited across two catchments subject to baiting with a commercial product (PIGOUT, Animal Control Technologies Australia, Melbourne, Vic., Australia). Three catchments were exempt from feral pig population management for the duration of this study. Key resultsFeral pig density within the overall study site was estimated as 1.127pigskm–2, resulting in 4580diggingskm–2year–1. There was no significant difference in feral pig density estimates observed among population management treatments or the treatment×year interaction term. An overall decrease in feral pig density across all catchments was attributed to extreme temperature and drought conditions experienced during the study. ConclusionsFeral pig populations demonstrate high resilience to current feral pig population management practices in the present study. The annual volume of soil disturbed by the numbers of feral pigs estimated across this study area is comparable to a commercial-scale resource extraction industry. We did not find significant differences in feral pig digging density among dominant vegetation types, but larger digs were associated with swamp vegetation. ImplicationsCurrent levels of feral pig population management did not reduce pig densities across eight catchments in the northern jarrah forest; therefore, more intensive population management is needed.

TO THE EDITOR: Goddard et al, authors of ?People with an intellectual disability in the discourse of chronic and complex conditions: an invisible group??1 are to be congratulated for raising discussion about one of the most vulnerable groups in Australia with respect to their receipt of optimal health care. The authors conclude that ?developing interventions and strategies to increase the knowledge of health care workers . . . caring for people with intellectual disabilities will likely improve the health care needs of this population and their families?. In relation to this identified need for health professional education and training in the care of people with intellectual disabilities, we would like to draw the attention of your readers to some work undertaken by the Centre for Developmental Disability Health Victoria (CDDHV) to address this issue. The CDDHV works to improve the health and health care of people with developmental disabilities through a range of educational, research and clinical activities. In recent years there has been an increasing awareness of the need for health professional education in this area. Moreover, as people with disabilities often have chronic and complex health and social issues, focusing on their health care provides a platform for interprofessional education and a springboard for understanding the essential importance and value of interprofessional practice. Recently, the CDDHV has taken a lead role in developing a teaching and learning resource that focuses both on the health care of people with disabilities and on the importance and value of interprofessional practice. This resource promotes and facilitates interprofessional learning, and develops understanding of the health and health care issues experienced by people with disabilities and those who support them. ?Health and disability: partnerships in action? is a new video-based teaching and learning package, produced through an interprofessional collaboration between health professionals from medicine, nursing, occupational therapy, physiotherapy, paramedic practice, health science, social work, speech pathology, dietetics and dentistry. Those living with a disability are the experts on their own experience and so their direct involvement in and contribution to the education of health care professionals is essential. The collaboration between those featured in the video stories and health professionals has led to the development of a powerful resource that facilitates students and practitioners developing insights into the health and health care issues encountered by people with developmental disabilities. We also believe that through improving their understanding of, and health provision to, people with disabilities and those who support them, health professionals will acquire valuable attitudes, knowledge and skills applicable to many other patients in their practice population.

Objective Most major Victorian hospitals include religious identity in routine admission demographic questions. However, approximately 20% of admissions do not have their religious identity recorded. At the Royal Melbourne Hospital this missing 20% was surveyed throughout 2014–15 for two reasons: (1) to enable patient care; and (2) to provide an insight into the significance of religious identity for patients. There is scarce literature on this subject, so the present mixed-methods study, including a qualitative component, will start to bridge the gap. Methods Mixed methods, cross-sectional survey. Results The quantitative component of the study found that religious identity was important for a significant proportion of our diverse population and that, in general, demographics were congruent with Australian Bureau of Statistics (ABS) census figures. The qualitative component also revealed significant complexity behind religious identity labels, which the census is unable to capture, providing an insight into the requirements of our growing multicultural population. Conclusions This study illustrates that religious identity is important for a majority of Royal Melbourne’s culturally diverse inpatients. This data would seem to give the practice of collecting religious identity data on admission new credence, especially as our culturally and linguistically diverse populations increase. In order to understand these nuances and provide appropriate care, skilled spiritual screening and assessment would appear to be not optional, but rather necessary in our increasingly complex healthcare future. What is known about the topic? A search of the literature using related terms (religious, religion, spiritual identity, care) revealed that there is scarce literature on the subject of religious identity and its importance and meaning to patients. What does this paper add? This mixed methods study approaches the issue of the importance of religious identity from the patient perspective via a spiritual screening survey that included a qualitative component, so will begin to bridge a gap in knowledge. What are the implications for practitioners? Improved understanding of the complexity of the spiritual needs of our Victorian multicultural population and commensurate emphasis on the need for individual spiritual screening and assessment.

Background Individuals who have both opposite- and same-sex partners have the potential to pass sexually transmitted infections (STIs) between high- and low-risk populations. Our aim was to examine assortative sexual mixing in terms of same-sex activity among male–female partnerships. Methods This was a retrospective repeated cross-sectional study of male–female partnerships attending the Melbourne Sexual Health Centre (MSHC) from 2015 to 2019. Sex of sexual partners was collected via computer-assisted self-interview. We calculated the proportion of partnerships where at least one individual reported same-sex partners in the previous 12 months and the degree of assortativity by bisexuality. Results A total of 2112 male–female partnerships (i.e. 4224 individuals) were included, with a median age of 27 years (IQR 23–31). Overall, 89.3% (1885/2112) of male–female partnerships did not report any other same-sex partners; however, in 9.5% (201/2112) of partnerships, same-sex partners were reported by one individual and in 1.2% (26/2112) of partnerships, both individuals reported same-sex partners. Bisexuality appeared to be slightly assortative in male–female partnerships (r = 0.163, 95% CI: 0.150–0.176; P < 0.001). Conclusion One in 10 individuals in male–female partnerships had at least one same-sex partner within the previous 12 months. Individuals were minorly selective by bisexuality, suggesting the patterns of bisexual mixing in male–female partners are more variable and this may have a significant impact on STI transmission in heterosexual populations.

We isolated 24 novel polymorphic microsatellite markers from the tawny frogmouth, a nocturnal bird endemic to Australia, which has successfully adapted to urban environments. Initially, 454 shotgun sequencing was used to identify 733 loci with primers designed. Of these, we trialled 30 in the target species of which all amplified a product of expected size. Subsequently, all 30 of these loci were screened for variation in 25 individuals, from a single population in Melbourne, Victoria, Australia. Twenty-eight loci were polymorphic with observed heterozygosity ranging from 0.03 to 0.96 (mean 0.58) and the number of alleles per locus ranged from 2 to 18 (average of 6.5); we confirmed that 24 loci conformed to Hardy–Weinberg expectations. The 24 loci identified here will be sufficient to unequivocally identify individuals and will be useful in understanding the reproductive ecology, population genetics and the gene flow amongst localities in urban environments where this bird thrives.

Background The most severe thunderstorm asthma (TA) event occurred in Melbourne on the 21st November 2016 and during this period, daily pollen information was available and accessible on smart devices via an App. An integrated survey within the App allows users to self-report symptoms. Objective To explore patterns of symptom survey results during the period when the TA event occurred. Methods Symptom data from the Melbourne Pollen Count and Forecast App related to asthma history, hay fever symptoms, and medication use was explored. A one-week control period before and after the event was considered. Chi-square tests and logistic regression were used to assess associations between sex, age, symptoms, and medication use. Results Of the 28,655 responses, during the 2016 pollen season, younger (18 to 40 years) males, with no hay fever and no asthma were the most single and regular responders. During the TA event for new users, sex was only significantly associated with hay fever ( p = 0.008) of which 60.2% of females’ responses reported having hay fever, while 43% of males’ responses did not. Those with mild symptoms peaked during the TA event. Conclusions Many individuals completed the survey on the app for the first time during the TA event indicating the potential of digital technologies to be used as indicators of health risk among populations at risk of TA events.

IntroductionNeonatal endotracheal intubation is an essential but potentially destabilising procedure. With an increased focus on avoiding mechanical ventilation, particularly in preterm infants, there are fewer opportunities for clinicians to gain proficiency in this important emergency skill. Rates of successful intubation at the first attempt are relatively low, and adverse event rates are high, when compared with intubations in paediatric and adult populations. Interventions to improve operator success and patient stability during neonatal endotracheal intubations are needed. Using nasal high flow therapy extends the safe apnoea time of adults undergoing upper airway surgery and during endotracheal intubation. This technique is untested in neonates.Methods and analysisThe Stabilisation with nasal High flow during Intubation of NEonates (SHINE) trial is a multicentre, randomised controlled trial comparing the use of nasal high flow during neonatal intubation with standard care (no nasal high flow). Intubations are randomised individually, and stratified by site, use of premedications, and postmenstrual age (<28 weeks’ gestation; ≥28 weeks’ gestation). The primary outcome is the incidence of successful intubation on the first attempt without physiological instability of the infant. Physiological instability is defined as an absolute decrease in peripheral oxygen saturation >20% from preintubation baseline and/or bradycardia (<100 beats per minute).Ethics and disseminationThe SHINE trial received ethical approval from the Human Research Ethics Committees of The Royal Women’s Hospital, Melbourne, Australia and Monash Health, Melbourne, Australia. The trial is currently recruiting in these two sites. The findings of this study will be disseminated via peer-reviewed journals and presented at national and international conferences.Trial registration numberACTRN12618001498280.

Abstract Aim Pregnancy outcomes in women with Sickle Cell Disease (SCD) have traditionally been poor with rates of both maternal and fetal complications greater than that seen in non-SCD populations (Oteng-Ntim et al, 2015). This association has been demonstrated across both low- and high-income countries with no significant correlation to discrepancies in health care (Boafor et al, 2015). Complications associated with pregnancy in SCD include preterm delivery, intrauterine growth restriction (IUGR), low birth weight, fetal distress in labour, Cesarean section, eclampsia, sickle cell vaso-occlusive crisis, infection, postpartum hemorrhage, and perinatal and maternal death. The introduction of prophylactic Red Cell Exchange (RCE) for high-risk SCD patients has seen a significant reduction in SCD-associated morbidity and mortality (Josephson et al, 2007). Limited studies have examined whether prophylactic RCE also translates to improved pregnancy outcomes in the SCD population with mixed conclusions (Asma et al, 2015). Whilst the association between SCD and adverse pregnancy outcomes has been well characterised in large multi-centre retrospective studies internationally, local data of pregnancy outcomes in SCD, particularly in patients receiving regular RCE, is lacking. Method We conducted a retrospective review of pregnancies within the SCD population managed at the Royal Melbourne Hospital between 2001 (date of commencement of regular RCE program) and 2018 to identify pregnancy complications and outcomes. Medical records across two sites (the Royal Melbourne Hospital and the Royal Women's Hospital) were reviewed to identify patient demographics, RCE received, mode and date of delivery, birth weight, fetal and maternal complications, and outcome of pregnancy. Results We identified 10 pregnancies amongst 5 patients with SCD managed during this time. Three patients had HbSS and two HbSC disease. Mean maternal age at time of pregnancy was 27 years. Two patients were receiving regular RCE prior to pregnancy and continued throughout at 3 to 4 week intervals, with a further patient commenced on RCE at 27/40 as per local hospital practice. Of the 3 women receiving regular RCE during pregnancy, all had live births (n=7); 1 via normal vaginal delivery (NVD) and 6 elective Cesarean-section due to cephalopelvic disproportion. Six of these pregnancies were at term, with one induced at 32/40 due to line sepsis as a complication of RCE. Two pregnancies were also complicated by gestational diabetes. Two patients were not managed with regular RCE. The first declined treatment throughout both pregnancies, with pregnancy 1 complicated by intrauterine growth restriction (IUGR) with delivery via NVD at 37/40, and pregnancy 2 complicated by placental abruption and fetal death in utero (FDIU) at 22/40. Both pregnancies were also complicated by gestational thrombocytopenia. The second patient was on hydroxyurea (HU) at time of conception, initially continued during pregnancy in the setting of normal morphology scans and a rare blood phenotype prohibitive of RCE. HU was subsequently ceased at 27/40 due to the development of IUGR. She was commenced on RCE at 30/40 but suffered placental abruption and FDIU at 34/40. No offspring had a haemoglobinopathy of clinical significance. Conclusion RCE was well-tolerated and associated with good and possibly improved maternal and fetal outcomes in this small cohort of sickle cell patients. Larger studies are required to further characterise the benefit of prophylactic RCE during pregnancy in the SCD population.

IntroductionThe advent of direct acting antiviral therapy for hepatitis C virus (HCV) means the elimination of HCV is possible but requires sustained effort to achieve. Between 2016 and 2019, 44% of those living with HCV were treated in Australia. However, treatment uptake has declined significantly. In Australia, people who inject drugs (PWID) are the population most at risk of HCV acquisition. Eliminating HCV in Australia will require nuanced understanding of the barriers to HCV treatment experienced by PWID and tailored interventions to address these barriers. The EC-Experience Cohort study aims to explore the barriers and enablers reported by PWID to engagement in HCV care.Methods and analysisThe EC-Experience Cohort study is a prospective cohort of PWID, established in Melbourne, Australia in 2018. Participants are assigned into three study groups: (1) those not currently engaged in HCV testing; (2) those diagnosed with HCV but not currently engaged in treatment and (3) those completed treatment. Participants complete a total of four interviews every 6 months across an 18-month study period. Predictors of experience of key outcome events along the HCV care cascade will be explored over time.Ethics and disseminationEthical approval for the EC-Experience Cohort study was obtained by the Alfred Hospital Ethics Committee in Melbourne, Australia (Project Number: HREC/16/Alfred/164). All eligible participants are assessed for capacity to consent and partake in a thorough informed consent process. Results from the EC-Experience Cohort study will be disseminated via national and international scientific and public health conferences and peer-reviewed journal publications. Data from the EC-Experience Cohort study will improve the current understanding of the barriers to HCV care for PWID and guide the tailoring of service provision for specific subgroups. Understanding the barriers and how to increase engagement in care of PWID is critical to achieve HCV elimination goals.

Chlamydia is the most common notifiable infectious disease in Australia with the number of notifications increasing 92% over the past 5 years. The "Sex and Sport" Project is piloting a community based chlamydia testing and treatment program reaching young people in a specific community setting, sporting clubs. This multifaceted approach utilises health education, population screening and collection of data on risk taking behaviour as the first steps in enhancing health and shaping future service provisions. The project's primary aim is to assess the feasibility of an outreach testing and treatment program. Secondary aims are to measure the prevalence of chlamydia and assess sexual risk behaviour in this population. Strong community collaborations and integration into local health services through the Primary Care Partnerships is important in the project's sustainability; in particular key community members respected by sporting clubs needed to be identified, capacity developed to deliver effective health promotion messages and improve young people's access to sexual health services. Additionally, local knowledge has guided overall program implementation and provides opportunities for capacity building to regionally based services. For example, poor access to sexual health services is being addressed by the participants being able to access services via telephone consultation with Melbourne Sexual Health Centre. Approximately 1000 Victorians aged 16-25 years from the Loddon Mallee region of Victoria will be tested between June and September 2007. This paper will report on the feasibility, challenges and possible solutions in establishing a community based outreach testing and treatment program.
