- Reproductive timing in many taxa plays a key role in determining breeding productivity(1), and is often sensitive to climatic conditions(2). Current climate change may alter the timing of breeding at different rates across trophic levels, potentially resulting in temporal mismatch between the resource requirements of predators and their prey(3). This is of particular concern for higher-trophic-level organisms, whose longer generation times confer a lower rate of evolutionary rescue than primary producers or consumers(4). However, the disconnection between studies of ecological change in marine systems makes it difficult to detect general changes in the timing of reproduction(5). Here, we use a comprehensive meta-analysis of 209 phenological time series from 145 breeding populations to show that, on average, seabird populations worldwide have not adjusted their breeding seasons over time (-0.020 days yr(-1)) or in response to sea surface temperature (SST) (-0.272 days degrees C-1) between 1952 and 2015. However, marked between-year variation in timing observed in resident species and some Pelecaniformes and Suliformes (cormorants, gannets and boobies) may imply that timing, in some cases, is affected by unmeasured environmental conditions. This limited temperature-mediated plasticity of reproductive timing in seabirds potentially makes these top predators highly vulnerable to future mismatch with lower-trophic-level resources(2).

- Introduction: Post-traumatic stress disorder (PTSD) and substance use disorder frequently co-occur and tend to have their onset during adolescence. Although research has highlighted the importance of treating these disorders in an integrated fashion, there is a dearth of empirically validated integrated treatment options for adolescents with this comorbidity. This paper describes the study protocol for a randomised controlled trial (RCT) examining the efficacy of an integrated trauma-focused cognitive–behavioural treatment for traumatic stress and substance use among adolescents (Concurrent Treatment of PTSD and Substance Use Using Prolonged Exposure - Adolescent (COPE-A)), relative to a supportive counselling control condition (Person-Centred Therapy (PCT)). Methods and analysis: A two-arm, parallel, single-blind RCT with blinded follow-up at 4 and 12 months poststudy entry will be conducted in Sydney, Australia. Participants (n~100 adolescents aged 12–18 years) and their caregivers (caregiver participation is optional) will be allocated to undergo either COPE-A or PCT (allocation ratio 1:1) using minimisation. Both therapies will be delivered individually by project psychologists over a maximum of 16 sessions of 60–90 min duration and will include provision of up to four 30 min optional caregiver sessions. The primary outcome will be between-group differences in change in the severity of PTSD symptoms from baseline to 4-month follow-up, as measured by the Clinician-Administered PTSD Scale for Children and Adolescents for DSM-5. Ethics and dissemination: Ethical approval has been obtained from the human research ethics committees of the Sydney Children’s Hospital Network (HREC/17/SCHN/306) and the University of Sydney (HREC 2018/863). Findings will be published in peer-reviewed journals and presented at scientific conferences. Trial registration number: ACTRN12618000785202; Pre-reults.

- Background: For up to 50% of adolescents experiencing PTSD, the course of their illness is further complicated by co-occurring substance use. Despite this, evidence-based integrated treatment options for adolescents with this comorbidity remain sparse. To address this gap, we are conducting an RCT examining the efficacy of exposure-based therapy for co-occurring PTSD and substance use among adolescents. In this paper, we discuss some of the challenges associated with conducting an RCT in the population group and early observations from the trial. Method: A total of 100 adolescents aged 12–18 years will be recruited. Participants are randomized to receive up to 16 sessions of (i) the integrated exposure-based treatment (COPE-A) or (ii) supportive counselling (control). Blind interviews are conducted at baseline, 4- and 12-months. Substance use and PTSD are measured each therapy session. Results: To date, 20 people have been referred to the study with 17 screened for eligibility. A total of 13 were eligible to participate with nine consented and allocated to a condition. Challenges to trial execution include issues relating to the population group itself, involvement of parents/guardians and other health care providers, logistics, ethical and governance approvals, and resources. Discussion: Although there are significant challenges involved in conducting a trial such as this, they are by no means insurmountable. The study findings will improve our understanding of how to best treat PTSD and substance use during this critical develop-mental period. By intervening early in the trajectory ofthese disorders, it may be possible to prevent thesevere and long-lasting burden associated withcomorbidity across the lifespan.

Tidskriftsartikel (refereegranskat)abstract
- Adolescence and emerging adulthood are key developmental stages with high risk for trauma exposure and the development of mental and substance use disorders (SUDs). The aim of this study was to compare the clinical profiles of adolescents (aged 12-17 years) and emerging adults (aged 18-25 years) presenting for treatment of posttraumatic stress disorder (PTSD) and SUD. Design/methodology/approach: Data was collected from the baseline assessment of individuals (n = 55) taking part in a randomized controlled trial (RCT) examining the efficacy of an integrated psychological therapy for co-occurring PTSD and SUDs (PTSD+SUD) in young people.Both age groups demonstrated complex and severe clinical profiles, including high frequency trauma exposure, and very poor mental health reflected on measures of PTSD, SUD, suicidality, and domains of social, emotional, behavioral and family functioning. There were few differences in clinical characteristics between the two groups. Similarity between the two groups suggests that the complex problems seen in emerging adults with PTSD+SUD are likely to have had their onset in adolescence or earlier, and to have been present for several years by the time individuals present for treatment. This is the first study to compare the demographic and clinical profiles of adolescents and emerging adults with PTSD+SUD. These findings yield important implications for practice and policy for this vulnerable group. Evidence-based prevention and early intervention approaches and access to care are critical. Alongside trauma-focused treatment, there is a critical need for integrated, trauma-informed approaches specifically tailored to young people with PTSD+SUD.

- Introduction and Aims: Up to 80% of adolescents have experienced trauma and one-in-seven suffer from post traumatic stress disorder (PTSD). For 50% of these adolescents, the course of their illness is further complicated by a co-occurring substance use disorder (SUD). Despite high rates of comorbidity, treatment options remain sparse and there is limited understanding of the clinical profile associated with this comorbidity. We aimed to examine the clinical profile of adolescents seeking treatment for their substance use and traumatic stress.Method: Data were collected as part of a randomised controlled trial examining the efficacy of an integrated psychological treatment for SUD and PTSD among young people aged 12-25 years were assessed for history of trauma, PTSD, substance use and a variety of other domains relating to mental health, social and family functioning and service utilisation.Results: Almost all participants met Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, criteria for a severe SUD. The most common substances of concern were cannabis and alcohol. All participants experienced multiple traumatic events and >85% met Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, criteria for PTSD. High levels of clinically elevated depression and anxiety were present in the sample and almost half had a history of attempted suicide.Discussions and Conclusions: Comorbid PTSD and SUD in young people are associated with a complex and severe clinical profile. It is imperative to intervene early in the trajectory in order to prevent the severe and long lasting burden associated with this common comorbidity.

Tidskriftsartikel (refereegranskat)abstract
- Post-traumatic stress disorder (PTSD) and substance use disorder (SUD) occur frequently as comorbid diagnoses among adolescents. Historically, these conditions have been treated using a sequential model; however, emerging evidence suggests that an integrated treatment model may be most effective. This article presents two de-identified clinical case studies from an ongoing randomised controlled trial examining the efficacy of an integrated, exposure-based, cognitive-behavioral psychotherapy (CBT) for PTSD and SUD among adolescents (COPE-A), relative to a supportive counselling control condition (person-centred therapy). In both case studies, participants were randomised to receive the COPE-A integrated treatment, which incorporates prolonged exposure (PE) including imaginal and in vivo exposure as a core treatment component alongside CBT for PTSD and SUD. The clinical profile and treatment response of each participant is discussed. Promising results were found in both cases, with substantially reduced traumatic stress symptoms and decreased or stable levels of substance use by the end of treatment. Clinical implications of these early findings are discussed.

Konferensbidrag (refereegranskat)abstract
- Up to 80% of adolescents have experienced trauma and one‐in‐seven suffer from post‐traumatic stress disorder (PTSD), a chronic, debilitating psychiatric disorder. For 50% of these adolescents, the course of their illness is further complicated by a co‐occurring substance use disorder, which often develops from repeated self‐medication of PTSD symptoms. Once established, both disorders serve to maintain and exacerbate the other leading to extensive social, educational, physical and psychological impairments and a chronic course of illness. It is imperative to intervene early in the trajectory in order to prevent the severe and long lasting burden associated with this common comorbidity. In this presentation we provide an overview of the evidence regarding treatment options available for co‐occurring PTSD and substance use, and promising new early interventions for adolescents. A review of the peer‐reviewed literature regarding treatment of PTSD and substance use was undertaken, and best practice approaches for the treatment of adolescents identified. There is growing evidence for the integrated treatment of PTSD and substance use disorders among adults, but the research pertaining to adolescents is in its infancy. Our current trial examining the efficacy of COPE‐A will provide much needed evidence as to how these conditions may best be treated in adolescence before they become chronic disabling conditions.

- Our symposium will explore the unique dynamics that give rise to and intensify ethical concerns with regards to AI technologies. The research presented will discuss topics such as how the design stage of an AI system cannot be isolated as an independent stage from the rest of the AI lifecycle. We will engage with the audience in meaningful discussion about the ethics of AI that is grounded both in the development stages as well as the use, implementation, and ongoing maintenance stages. The nascent field of AI ethics will greatly benefit from adopting a more processual and situated understanding of ethics with regards to AI tools and from empirically exploring the use of AI and its enacted ethical implications (Barley & Bailey, 2020). This symposium will provide a forum to explore current research in this area and foster discussions to enhance impact on both research and practice.
