Chapter 23: Climate change and Great Barrier Reef: industries and communities

Climate change is driving shifts in environmental conditions that, together with other human pressures, are impacting the Great Barrier Reef (GBR). Individuals, communities, and industries in the GBR catchment depend directly or indirectly on the GBR for ecosystem goods and services. These take the form of direct economic benefits (including commercial activities such as tourism and fishing), social services (including recreational activities and cultural linkages) and environmental services (including shoreline protection from barrier reefs and mangrove stands).This is Chapter 23 of Climate change and the Great Barrier Reef: a vulnerability assessment.

Findings from a national study to investigate how British universities are challenging sexual violence and harassment on campus and Sexual Violence Self-Assessment Checklist for Universities

The Universities UK Taskforce published its report on tackling violence against women, hate crime and harassment in UK universities in 2016 (UUK, 2016). The UUK report identified seven key components for change (UUK, 2016: p59): 1. A commitment from senior leadership; 2. Ensuring an institution-wide approach; 3. Prevention of incidents; 4. Enabling an effective response; 5. Managing situations where students have committed an offence; 6. Sharing of good practice; 7. Assessment of support needed with regards to online harassment. Many universities in England and Wales received HEFCE funding to tackle the violence against women (VAWG) work stream forward. Our study investigates the future sustainability of such initiatives

Early evaluation of the Children and Young People's Mental Health Trailblazer programme:a rapid mixed-methods study

BACKGROUND: The Children and Young People’s Mental Health Trailblazer programme is funding the creation of new mental health support teams to work in schools and further education colleges. Mental health support teams directly support children and young people with ‘mild to moderate’ mental health problems and work with school and college staff to promote well-being for all. A new workforce of education mental health practitioners is being trained for the teams. OBJECTIVE(S): The National Institute for Health and Care Research Birmingham, RAND and Cambridge Evaluation Rapid Evaluation Centre and Policy Innovation and Evaluation Research Unit undertook an early evaluation of the Trailblazer programme to examine the development, implementation and early progress of mental health support teams in the programme’s first 25 ‘Trailblazer’ sites. DESIGN: A mixed-methods evaluation, comprising three work packages: 1. Establishing the baseline and understanding the development and early impacts of the Trailblazer sites, including two rounds of surveys with key informants and participating education settings in all 25 sites. 2. More detailed research in five purposively selected Trailblazer sites, including interviews with a range of stakeholders and focus groups with children and young people. 3. Scoping and developing options for a longer-term assessment of the programme’s outcomes and impacts. Fieldwork was undertaken between November 2020 and February 2022. The University of Birmingham Institute for Mental Health Youth Advisory Group was involved throughout the study, including co-producing the focus groups with children and young people. RESULTS: Substantial progress had been made implementing the programme, in challenging circumstances, and there was optimism about what it had the potential to achieve. The education mental health practitioner role had proven popular, but sites reported challenges in retaining education mental health practitioners, and turnover left mental health support teams short-staffed and needing to re-recruit. Education settings welcomed additional mental health support and reported positive early outcomes, including staff feeling more confident and having faster access to advice about mental health issues. At the same time, there were concerns about children who had mental health problems that were more serious than ‘mild to moderate’ but not serious enough to be accepted for specialist help, and that the interventions offered were not working well for some young people. Mental health support teams were generally spending more time supporting children with mental health problems than working with education settings to develop ‘whole school’ approaches to mental health and well-being, and service models in some sites appeared to be more clinically oriented, with a strong focus on mental health support teams’ therapeutic functions. LIMITATIONS: Despite efforts to maximise participation, survey response rates were relatively low and some groups were less well represented than others. We were not able to gather sufficiently detailed data to develop a typology of Trailblazer sites, as was planned. CONCLUSIONS: Key lessons for future programme implementation include: - Whether mental health support teams should expand support to children and young people with more complex and serious mental health problems. - How to keep the twin aims of prevention and early intervention in balance. - How to retain education mental health practitioners once trained. FUTURE WORK: The findings have important implications for the design of a longer-term impact evaluation of the programme, which is due to commence in summer 2023

Ecological and evolutionary drivers of hemoplasma infection and bacterial genotype sharing in a Neotropical bat community

Most emerging pathogens can infect multiple species, underlining the importance of understanding the ecological and evolutionary factors that allow some hosts to harbour greater infection prevalence and share pathogens with other species. However, our understanding of pathogen jumps is based primarily around viruses, despite bacteria accounting for the greatest proportion of zoonoses. Because bacterial pathogens in bats (order Chiroptera) can have conservation and human health consequences, studies that examine the ecological and evolutionary drivers of bacterial prevalence and barriers to pathogen sharing are crucially needed. Here were studied haemotropic Mycoplasma spp. (i.e., haemoplasmas) across a speciesâ€rich bat community in Belize over two years. Across 469 bats spanning 33 species, half of individuals and twoâ€thirds of species were haemoplasma positive. Infection prevalence was higher for males and for species with larger body mass and colony sizes. Haemoplasmas displayed high genetic diversity (21 novel genotypes) and strong host specificity. Evolutionary patterns supported codivergence of bats and bacterial genotypes alongside phylogenetically constrained host shifts. Bat species centrality to the network of shared haemoplasma genotypes was phylogenetically clustered and unrelated to prevalence, further suggesting rare—but detectable—bacterial sharing between species. Our study highlights the importance of using fine phylogenetic scales when assessing host specificity and suggests phylogenetic similarity may play a key role in host shifts not only for viruses but also for bacteria. Such work more broadly contributes to increasing efforts to understand crossâ€species transmission and the epidemiological consequences of bacterial pathogens

One Health – an Ecological and Evolutionary Framework for tackling Neglected Zoonotic Diseases

Understanding the complex population biology and transmission ecology of multihost parasites has been declared as one of the major challenges of biomedical sciences for the 21st century and the Neglected Zoonotic Diseases (NZDs) are perhaps the most neglected of all the Neglected Tropical Diseases (NTDs). Here we consider how multihost parasite transmission and evolutionary dynamics may affect the success of human and animal disease control programmes, particularly neglected diseases of the developing world. We review the different types of zoonotic interactions that occur, both ecological and evolutionary, their potential relevance for current human control activities, and make suggestions for the development of an empirical evidence base and theoretical framework to better understand and predict the outcome of such interactions. In particular, we consider whether preventive chemotherapy, the current mainstay of NTD control, can be successful without a One Health approach. Transmission within and between animal reservoirs and humans can have important ecological and evolutionary consequences, driving the evolution and establishment of drug resistance, as well as providing selective pressures for spill‐over, host switching, hybridizations and introgressions between animal and human parasites. Our aim here is to highlight the importance of both elucidating disease ecology, including identifying key hosts and tailoring control effort accordingly, and understanding parasite evolution, such as precisely how infectious agents may respond and adapt to anthropogenic change. Both elements are essential if we are to alleviate disease risks from NZDs in humans, domestic animals and wildlife

HIV Testing and Sexual Health Among Black African Men and Women in London, United Kingdom

Importance: Black African adults are disproportionately affected by HIV in the United Kingdom. Many within this population acquire HIV after migration or are diagnosed late. Data are needed to inform targeted interventions to increase HIV testing and prevention in this population. Objective: To inform future HIV prevention strategies by estimating diagnosed and undiagnosed HIV infection and measuring changes in HIV testing rates in black African adults in London, United Kingdom. Design, Setting, and Participants: This cross-sectional study used a self-completed survey conducted from September 20 to December 3, 2016. Questionnaires were linked to an optional, anonymous oral fluid HIV test and compared with data from a previous survey (2004). Respondents were recruited from social and commercial venues frequented by black African adults in London. Of 2531 individuals approached in 63 venues, 752 agreed to participate. Data were analyzed initially in March 2017 (as part of internal reporting) and again in August 2018. Main Outcomes and Measures: Self-reported HIV testing within the past 5 years; diagnosed and undiagnosed HIV prevalence. Logistic regression examined factors associated with HIV testing by sex. Results: In total, 292 women (median [interquartile range] age, 31 [25.0-41.5] years) and 312 men (median [interquartile range] age, 35 [25.0-41.5] years) were included in the analysis. More than half of men (159 [51.0%]) and women (154 [52.7%]) had been tested for HIV in the past 5 years. In multivariable analysis, HIV testing was associated with a range of factors in both sexes, including health service attendance, time in the United Kingdom, and sexually transmitted infection diagnosis. Increases in HIV testing in the past 5 years were observed between 2004 and 2016 for both sexes. In the 2016 sample, 219 of 235 women (93.2%) and 206 of 228 men (90.4%) tested HIV negative. Among those testing positive, 56.3% of women (9 of 16) and 40.9% of men (9 of 22) self-reported as HIV negative or untested, indicating they were living with undiagnosed HIV. A fifth of women (20.7%) and 25.0% of men reported condomless last sex with a partner of different or unknown HIV status in the past year. Conclusions and Relevance: Despite efforts to increase HIV testing, uptake in black African communities in London remains modest. This study identified a large fraction of undiagnosed infection-greater than other at-risk populations-suggesting that the prevention and care needs of this group are not adequately met

The experiential impact of hospitalisation:parents' accounts of caring for young people with early psychosis

This research examines the experiential impact of hospitalisation on the parents of young people with early psychosis. In-depth interviews were conducted with a small sample of parents, and the resulting transcripts were analysed using Interpretative Phenomenological Analysis. Five themes emerged from the data: Accepting and blaming, Feeling out of control, Hospitalisation as temporary containment, Feeling let down by services and Stigma. Aspects of the hospitalisation process were characterised by parents as generally negative, but a number of positive affirmations were also offered regarding the containing, supportive and crucial role of services. Parents' perceptions of hospitalisation as a difficult, and sometimes distressing, experience are exacerbated by the complexity of being the carer of a young person. Negotiating services and boundaries within the context of this relationship contributes to feelings of exclusion and disregard by professionals and services. The implications of this study resonate with the current government mental health strategy with regard to how services can engage and include carers in the mental health system, and equip and enable them to support their relatives with early psychosis

Targeted inactivation of the EGF and amphiregulin genes reveals distinct roles for EGF receptor ligands in mouse mammary gland development

Targeted mice lacking functional EGF or amphiregulin (AR) were derived and bred to the TGFalpha-knockout to generate mice lacking various combinations of the three ligands. In contrast to EGF receptor (EGFR) knockout mice, triple null mice lacking half of the EGFR ligand family were healthy and fertile, indicative of overlapping or compensatory functions among EGF family members. Nevertheless, pups born to triple null dams frequently died or were runted, suggesting a mammary gland defect. Comparison of individual and combinatorial knockouts established that specific loss of AR severely stunted ductal outgrowth during puberty, consistent with dramatic expression of AR transcripts in normal developing ducts. Surprisingly, loss of all three ligands did not significantly affect cellular proliferation, apoptosis, or ERK activation within terminal end buds. Following pregnancy, most AR single null females, but few triple null females could nurse their young, revealing collaborative roles for EGF and TGFalpha in mammopoiesis and lactogenesis. In triple null glands, alveoli were poorly organized and differentiated, and milk protein gene expression was decreased. Additionally, Stat5a activation was frequently reduced in AR single and combinatorial nulls in association with impaired lactation. Collectively, our results provide genetic confirmation of a requirement for EGFR signaling throughout the development of the mouse mammary gland, and reveal stage-dependent activities for different EGFR ligands. Finally, the additional loss of growth factors from pups nursed by triple null dams further worsened their survival and growth, establishing functions for both maternal- and neonatal-derived growth factors
