- Abstract
Background: The COVID-19 pandemic heightened risks for individuals with hematological malignancies due to compromised immune systems, leading to more severe outcomes and increased mortality. While interventions like vaccines, targeted antivirals, and monoclonal antibodies have been effective for the general population, their benefits for these patients may not be as pronounced. Methods: The EPICOVIDEHA registry (National Clinical Trials Identifier, NCT04733729) gathers COVID-19 data from hematological malignancy patients since the pandemic's start worldwide. It spans various global locations, allowing comprehensive analysis over the first three years (2020–2022). Findings: The EPICOVIDEHA registry collected data from January 2020 to December 2022, involving 8767 COVID-19 cases in hematological malignancy patients from 152 centers across 41 countries, with 42% being female. Over this period, there was a significant reduction in critical infections and an overall decrease in mortality from 29% to 4%. However, hospitalization, particularly in the ICU, remained associated with higher mortality rates. Factors contributing to increased mortality included age, multiple comorbidities, active malignancy at COVID-19 onset, pulmonary symptoms, and hospitalization. On the positive side, vaccination with one to two doses or three or more doses, as well as encountering COVID-19 in 2022, were associated with improved survival. Interpretation: Patients with hematological malignancies still face elevated risks, despite reductions in critical infections and overall mortality rates over time. Hospitalization, especially in ICUs, remains a significant concern. The study underscores the importance of vaccination and the timing of COVID-19 exposure in 2022 for enhanced survival in this patient group. Ongoing monitoring and targeted interventions are essential to support this vulnerable population, emphasizing the critical role of timely diagnosis and prompt treatment in preventing severe

- Abstract
Background: The outcome of COVID-19 in allogeneic hematopoietic stem cell transplantation (HSCT) recipients is almost uniformely considered poor. The aim of present study was to retrospectively analyse the outcome and risk factors for mortality in a large series of patients who developed COVID-19 infection after an allogeneic HSCT. Methods: This multicenter retrospective study promoted by the European Hematology Association – Infections in Hematology Study Working Group, included 326 adult HSCT patients who had COVID-19 between January 2020 and March 2022. Results: The median time from HSCT to the diagnosis of COVID-19 was 268 days (IQR 86-713; range 0-185 days). COVID-19 severity was mild in 21% of the patients, severe in 39% and critical in 16% of the patients. In multivariable analysis factors associated with a higher risk of mortality were, age above 50 years, presence of 3 or more comorbidities, active hematologic disease at time of COVID-19 infection, development of COVID-19 within 12 months of HSCT, and severe/critical infections. Overall mortality rate was 21% (n=68): COVID-19 was the main or secondary cause of death in 16% of the patients (n=53). Conclusions: Mortality in HSCT recipients who develop COVID-19 is high and largely dependent on age, comorbidities, active hematologic disease, timing from transplant and severity of the infection.

- Abstract
Objectives: Elderly patients with hematologic malignancies face the highest risk of severe COVID-19 outcomes. The infection's impact on different age groups remains unstudied in detail. Methods: We analyzed elderly patients (age groups: 65-70, 71-75, 76-80, and >80 years old) with hematologic malignancies included in the EPICOVIDEHA registry between January 2020 and July 2022. Univariable and multivariable Cox regression models were conducted to identify factors influencing death in COVID-19 patients with hematological malignancy. Results: The study included data from 3,603 elderly patients (aged 65 or older) with hematological malignancy, with a majority being male (58.1%) and a significant proportion having comorbidities. The patients were divided into four age groups, and the analysis assessed COVID-19 outcomes, vaccination status, and other variables in relation to age and pandemic waves. The 90-day survival rate for patients with COVID-19 was 71.2%, with significant differences between groups. The pandemic waves had varying impacts, with the first wave affecting patients over 80 years old, the second being more severe in 65-70, and the third being the least severe in all age groups. Factors contributing to 90-day mortality included age, comorbidities, lymphopenia, active malignancy, acute leukemia, less than three vaccine doses, severe COVID-19, and using only corticosteroids as treatment. Conclusion: These data underscore the heterogeneity of elderly hematological patients, highlight the different impacts of COVID-19 waves and the pivotal importance of vaccination, and may help in planning future healthcare efforts.

Effective host directed therapies (HDTs) are critical to improve survival and clinical outcomes. Currently only one HDT, dexamethasone, is proven to improve mortality. However, there is no evidence dexamethasone reduces morbidity, how it reduces mortality is uncertain, and it has no proven benefit in HIV co-infected individuals. Further research on these aspects of its use, as well as alternative HDTs such as aspirin, thalidomide and other immunomodulatory drugs is needed. Based on new knowledge from pathogenesis studies, repurposed therapeutics which act upon small molecule drug targets may also have a role in TBM. Here we review existing literature investigating HDTs in TBM, and propose new rationale for the use of novel and repurposed drugs. We also discuss host variable responses and evidence to support a personalised approach to HDTs in TBM.

Tuberculous Meningitis International Research Consortium ,urologic and male genital diseases - Abstract
The pathogenesis of Tuberculous meningitis (TBM) is poorly understood, but contemporary molecular biology technologies have allowed for recent improvements in our understanding of TBM. For instance, neutrophils appear to play a significant role in the immunopathogenesis of TBM, and either a paucity or an excess of inflammation can be detrimental in TBM. Further, severity of HIV-associated immunosuppression is an important determinant of inflammatory response; patients with the advanced immunosuppression (CD4+ T-cell count of 150 cells/μL. Host genetics may also influence outcomes with LT4AH genotype predicting inflammatory phenotype, steroid responsiveness and survival in Vietnamese adults with TBM. Whist in Indonesia, CSF tryptophan level was a predictor of survival, suggesting tryptophan metabolism may be important in TBM pathogenesis. These varying responses mean that we must consider whether a “one-size-fits-all” approach to anti-bacillary or immunomodulatory treatment in TBM is truly the best way forward. Of course, to allow for proper treatment, early and rapid diagnosis of TBM must occur. Diagnosis has always been a challenge but the field of TB diagnosis is evolving, with sensitivities of at least 70% now possible in less than two hours with GeneXpert MTB/Rif Ultra. In addition, advanced molecular techniques such as CRISPR-MTB and metagenomic next generation sequencing may hold promise for TBM diagnosis. Host-based biomarkers and signatures are being further evaluated in childhood and adult TBM as adjunctive biomarkers as even with improved molecular assays, cases are still missed. A better grasp of host and pathogen behaviour may lead to improved diagnostics, targeted immunotherapy, and possibly biomarker-based, patient-specific treatment regimens.

Astronautics (General) - Abstract
The implementation of the HST system safety program is detailed. Numerous safety analyses are conducted through various phases of design, test, and fabrication, and results are presented to NASA management for discussion during dedicated safety reviews. Attention is given to the system safety assessment and risk analysis methodologies used, i.e., hazard analysis, fault tree analysis, and failure modes and effects analysis, and to how they are coupled with engineering and test analysis for a 'synergistic picture' of the system. Some preliminary safety analysis results, showing the relationship between hazard identification, control or abatement, and finally control verification, are presented as examples of this safety process.

Sim, C, Bahr, N, Curtis, Elizabeth, Sim, C, Bahr, N, and Curtis, Elizabeth
- Abstract
There is little conjecture that quality teaching is essential to student achievement and well-being. Whilst much has been written about the importance of quality teaching, including the link to pre-service teacher education, to date there has been little investigation into specific pedagogical practices that can enhance quality teaching dimensions within a pre-service teacher education programme. This paper reports on a small-scale qualitative research study, undertaken in an Australian university, which linked the fields of quality teaching, pre-service teacher education and values education. The study followed the journey of five pre-service teacher education students as they undertook their second field experience unit where the focus was centred on the values-based pedagogy of Philosophy in the Classroom. The research findings, collected via interviews, demonstrated that an explicit values-based pedagogy can have a positive impact on the development of quality teaching dimensions. This new knowledge has potential for further research into examining the ways quality teaching dimensions are gained and practised by pre-service teacher education students and these findings and recommendations are discussed in this paper.

- Abstract
Robotics has created opportunities for educators to teach concepts across Science, Technology, Engineering, and Mathematics (STEM). This is one of the reasons robotics is becoming increasingly common in primary and secondary classrooms in Australia. To enable pre-service teachers to design engaging STEM activities that incorporate these technologies, robotics is part of the teaching program in the primary education degree at Queensland University of Technology (QUT). A number of pre-service teachers also choose to extend their abilities by implementing robotics activities on field studies, in schools on a voluntary basis, and in outreach activities such as the Robotics@QUT project. The Robotics@QUT project is a support network developed to build professional knowledge and capacity of classroom teachers in schools from a low SES area, engaging in robotics-based STEM activities. Professional Development (PD) workshops are provided to teachers in order to build their knowledge and confidence in implementing robotics activities in their classrooms, loan kits are provided, and pre-service teacher visits arranged to provide the teachers with on-going support. A key feature of the project is the partnerships developed between the teachers and the pre-service teachers involved in the project. The purpose of this study was to ascertain how the teachers in the project perceived the value of the PD workshops and the pre-service teachers’ involvement and what the benefits of the involvement in the project were for the pre-service teachers. Seventeen teachers completed a five-point (1-5) likert scale questionnaire regarding their involvement in the Robotics@QUT project. Teachers’ responses on the value of the project and the pre-service teacher support highlighted the benefits of the partnerships formed and provided insights into the value of the support provided by the pre-service teachers. This paper also describes one pre-service teacher’s experience with the project and the

- Abstract
Contemporary course designers in schools and faculties of Education are finding themselves dancing to many tunes, arguably too many tunes, in order to have their initial teacher education courses accredited by external agencies whilst satisfying internal approval processes and, critically, maintaining the philosophical integrity of their programs and their institutional watermarks. The “tunes” here are the agendas driven by and the demands made by distinct independent agencies. The external agencies influencing Education include: TEQSA (Tertiary Education Quality and Standards Agency) which will assure alignment to the AQF (Australian Qualifications Framework); professional bodies such as AITSL (Australian Institute for Teaching and School Leadership) which now accredits all pre-service teacher Education courses across Australia and assures alignment with the Australian Professional Standards for Teachers; and the state and territory regulatory authorities that have an impact within a specific jurisdiction, for example, the Queensland College of Teachers (QCT) and the Teacher Registration Board of Western Australia (TRBWA). This paper – whose findings have been arrived at through a year-long OLT National Teaching Fellowship - will outline the complex and competing agendas currently at play and focus on the disjuncture evident in the fundamental defining of who is a “graduate.” It will also attempt to identify where there are synergies between the complex demands being made. It will argue that there are too many “tunes” and the task of finding a balance between compliance and delivering effective initial teacher education may not be possible because of the cacophony of their conflicting demands.

- Abstract
Mentoring relationships during pre-service education are a significant relationship through which emerging teachers negotiate their teacher identity (Iancu-Haddad & Oplatka, 2009; Hudson, 2010). It is therefore important to understand how mentor teachers frame their expectations. This paper explores mentoring relationships established within a Queensland partnership program funded through the Federal Government’s Improving Teacher Quality National Partnership Agreement (DEEWR, 2011). Within the broader policy context, these mentoring relationships were seen as an important space for pre-service teachers to experience cultural induction into Education Queensland schooling, and be advocates for quality teaching (Willis, Bahr, Bannah, & Welch, 2012). Interview and survey data from 14 teacher mentors were analysed using a dialectic constant comparison approach (Dick 2007). Three significant themes were identified. Mentor teachers’ understanding of their roles positioned pre-service teachers as either novices or alternatively as colleagues, and these had implications for the opportunities for learning that were then made available to the pre-service teachers. The mentor teacher’s beliefs about teaching as a practical craft, and how the mentor teachers judged a pre-service teacher’s “enthusiasm” were also analysed. Understanding the factors that guide teacher mentor approaches may inform future designs of mentoring and preservice teacher preparation programs.

- Abstract
National Australian reviews advocate exploring new models for preservice teacher education. This study investigates the outcomes of the School-Community Integrated Learning (SCIL) pathway as a model for advancing preservice teachers’ understandings of teaching. Thirty-two final-year preservice teachers were surveyed with extended written responses on how the SCIL pathway advanced their understandings of teaching. Results indicated 100% agreement on 6 of the 27 survey items. Indeed, 78% or more preservice teachers agreed that they had a range of experiences across the five categories (i.e., personal-professional skill development, understandings of system requirements, teaching practices, student behaviour and reflective practices). Extended responses suggested they had developed understandings around setting up classrooms, whole school planning processes with professional development, the allocation of teacher responsibilities (e.g., playground duties), parent-teacher interviews, diagnostic testing for literacy and numeracy, commencing running records of students’ assessment results, and the development of relationships (students, teachers and parents). Although a longitudinal study is required to determine long-term effects, the SCIL pathway may be viewed as a positive step towards preparing final-year preservice teachers for their first year as fully-fledged teachers.

Sim, C, Bahr, N, Adie, Lenore, Sim, C, Bahr, N, and Adie, Lenore
- Abstract
Moderation of student assessment is a critical component of teaching and learning in contemporary universities. In Australia, moderation is mandated through university policies and through the new national university accreditation authority, Tertiary Education Quality and Standards Agency which began operations in late January 2012 (TEQSA, 2012). The TEQSA requirement to declare details of moderation and any other arrangements used to support consistency and reliability of assessment and grading across each subject in the course of study is a radical step intended to move toward heightened accountability and greater transparency in the tertiary sector as well as entrenching evidence-based practice in the management of Australian academic programs. In light of this reform, the purpose of this project was to investigate and analyse current moderation practices operating within a faculty of education at a large urban university in Queensland, Australia. This qualitative study involved interviews with the unit coordinators (n=21) and tutors (n=8) of core undergraduate education units and graduate diploma units within the faculty. Four distinct discourses of moderation that academics drew on to discuss their practices were identified in the study. These were: equity, justification, community building, and accountability. These discourses, together with recommendations for changes to moderation practices are discussed in this paper.

- Abstract
Theories provide us with a frame of reference or model of how something works. Theoreticians who focus on the human state try to make a best-fit model. They try to imagine a typical case and generate a set of frameworks that might assist us to predict behaviour or some outcome, or simply explain how things work. They aim to understand how elements of interest might impact upon each other, and give rise to or predict behavioural, emotional, moral, physical, cognitive or social change for individuals and groups. Theories help give us insight. However, theories do not provide the templates for growth and change. They are simply someone’s informed and researched view regarding what might happen as people grow and interact with the physical and social world.

- Abstract
Through adolescence, young people are at an exciting point of their maturation. On the whole they are thoughtful, caring and responsible people. In many ways they are just beginning to make valuable contributions to the society they will soon be steering. They are critical and reflective, and they are passionate and energetic. We have discovered in earlier chapters the types of physical and cognitive changes and developments that confront adolescents. In this chapter we will explore emotional and moral development and allied issues of resilience and vulnerability. The emotional dimension of adolescence can tie in with several other issues that extend from aloneness, loneliness and alienation. We will introduce key theory and theorists in the field of emotional and moral development (such as Kohlberg). Some adolescents have a traumatic time (as do people of all ages and phases of life) and this book wouldn’t be whole without a brief discussion of the types of issues that emerge as young people in the throes of developing their moral and emotional perspective of the world are dealt life challenges.

- Abstract
As teachers, we must know about the physical developmental processes our students are experiencing. These are reflected in behaviour, emotions and relationships. And for adolescents, who are trying hard to figure out how the world operates, the physical changes they experience have a potent impact on their world view. While the sequencing of much of our physical development is pretty well according to a grand template and rolls out in much the same way from one person to the next, not everything occurs in a set way (Richter, 2006). Some aspects of our physical development cause other things to occur and are tied together. For example, hormonal changes during puberty are tied to the development of secondary sexual characteristics. However, there is individual variation at multiple levels, and we will discuss these. To complicate things, adolescents’ feelings and ideas about themselves and the ways in which they interact with the world as they grow and change are coloured by our societies’ multifaceted sets of ideals, standards and expectations for physical development. Many other things also impact on our conceptions of self and these will be discussed when we turn our attention to the development of identity through adolescence. In this chapter we will present some basic information about the types of physical changes to expect during adolescence, and consider some challenges that confront adolescents during this time of development.

- Abstract
'The Millennial Adolescent' offers contemporary, stimulating insights for those currently teaching as well as those preparing to teach. This book investigates the characteristics of Generation Y, using students own voices, generational theory and case studies. The text is structured around the principle that effective teachers need to know who they are teaching as well as what to teach, how to teach it, and how to assess the outcome. Using generational theory, 'The Millennial Adolescent' investigates the characteristics of Generation Y, or the Millennial Generation, and points out what all teachers need to know about working with this current generation of students who are described in a number of ways digital natives, team oriented, confident, multi-taskers, high achievers, and a generation unlike any other. The book contains well-known frameworks for developing understandings about adolescents, blended and contrasted with a contemporary socio-cultural construction of adolescence, set in our particular time, era and society. This book reflects the uniqueness of Australian contexts, while connecting with international trends and global patterns. Engaging and full of insights, this book is essential reading for all professionals dealing with adolescents.

- Abstract
Teacher education programs focussing on the development of specialist teachers for ‘the middle years’ have proliferated in Australian universities in recent years. This paper provides some insights into middle years’ teacher education programs at the University of Queensland, Edith Cowan and Flinders Universities with regard to their: philosophical underpinnings; specific educational context; scope and nature of the program. In addition, some of the research directions and efficacy strategies utilised in conjunction with the programs will be shared, along with some early findings from a longitudinal study in one of the programs. We propose that the pattern of programmatic growth heralds a new time for teacher education, and we speculate about the production of new kinds of teacher identities as graduates take their place in the profession.

- Abstract
Interdisciplinary studies are fundamental to the signature practices for the middle years of schooling. Middle years researchers claim that interdisciplinarity in teaching appropriately meets the needs of early adolescents by tying concepts together, providing frameworks for the relevance of knowledge, and demonstrating the linking of disparate information for solution of novel problems. Cognitive research is not wholeheartedly supportive of this position. Learning theorists assert that application of knowledge in novel situations for the solution of problems is actually dependent on deep discipline based understandings. The present research contrasts the capabilities of early adolescent students from discipline based and interdisciplinary based curriculum schooling contexts to successfully solve multifaceted real world problems. This will inform the development of effective management of middle years of schooling curriculum.

- Abstract
The young people who populate our classrooms live in a changed and rapidly changing society: a society where information is the most valued commodity and where traditional ‘truth’s such as nation and family are increasingly destabilized and fragmented. Educators at primary, secondary and tertiary level must, with some urgency, address issues relating the emergence of new citizenships and identities, the impact of new technologies and new economies. Our pedagogy and curriculums must be relevant to the need of students now and in the future. The School of Education, The University of Queensland is addressing issues of change, new technologies, new work places, critical citizenry and the need for pedagogical and curriculum innovation through the development of a new Middle Years of Schooling Dual Degree program. This program is designed to equip pre-service teachers to approach pedagogy and curriculum in innovative ways and to challenge them to embrace diversity and change. This paper outlines the key features of the Middle Years of Schooling Dual Degree, identifying a number of innovative approaches to pre-service teacher education.

Bahr, N. I., Palme, R., Mo¨hle, U., Hodges, J. K., and Heistermann, M.
- Abstract
A radiometabolism study is described to provide the first comparative data on the time course, route, and characteristics of excreted [3H]cortisol metabolites in three nonhuman primates: the common marmoset (Callithrix jacchus), the long-tailed macaque (Macaca fascicularis), and the chimpanzee (Pan troglodytes). A low dose (40–100 μCi) of 3H-labeled cortisol was administered intravenously to one adult male of each species and the excreta collected over a 5-day period postinjection. The major proportion of radioactivity was excreted in the urine (>80%). Peak radioactivity in urine was recovered within 5.5 h following injection in all three species, while in the feces peak levels of radioactivity were recovered within 26 h postinjection. In all three species, urinary metabolites were primarily excreted as conjugates (61–87%), whereas the percentage of conjugated metabolites in feces was 50% or less. The number and relative abundance of urinary and fecal [3H]cortisol metabolites were determined by reverse-phase high-performance liquid chromatography (HPLC) and immunoreactivity of the radioactivity peaks was assessed by screening HPLC fractions with established cortisol, corticosterone, and 11-oxoetiocholanolone enzyme immunoassays (EIA), the latter being a group-specific assay for measuring 11,17-dioxoandrostanes. HPLC separation of urinary and fecal extracts revealed multiple peaks of radioactivity, several of which were common to all three species. The relative proportion of these peaks, however, differed considerably among species and between urine and feces. HPLC indicated that native cortisol was a major urinary excretory product in the marmoset, while comparatively small amounts were present in the urine of the macaque and chimpanzee. In contrast, in feces, cortisol was only detected in low amounts in the marmoset and was virtually absent in the macaque and chimpanzee. In all three species, one of the major radioactivity peaks showed a retention time comparable to 11-oxoetiocholanolone and high immunoreactivity in the 11-oxoetiocholanolone EIA. The measurement of urinary- and/or fecal-immunoreactive 11,17-dioxoandrostanes is therefore implicated for noninvasive assessment of adrenal function in Old World monkeys, New World monkeys, and great apes.

This paper discusses the development of a new Bachelor of Education (Middle Years of Schooling) at The University of Queensland. The middle years of schooling have increasingly been the focus of education reform initiatives in Australia, but this has not been accompanied by significant increases in the number of teacher education institutions offering specialised middle schooling-level teacher preparation programmes. Considering the rapidly changing social and economic context and the emergent state of middle schooling in Australia, the programme represented a conceptual and practical opportunity and challenge for The University of Queensland team. Working collaboratively, the team sought to design a teacher education preservice programme that was both responsive and generative: that is, responsive to local school contexts and to current educational research and reform at national and international levels; and generative of cutting-edge theories and practices associated with middle schooling, teachers' work, and teacher education. This paper focuses on one component of the Middle Years of Schooling Teacher Education programme at The University of Queensland; namely, the practicum. We first present the underlying principles of the practicum programme and then examine "dilemmas" that emerged early in the practicum. These issues and tensions were associated with the ideals of "middle years" philosophy and the pragmatics of school reform associated with that new approach. In this paper, and within this context, we explore what it means to be both responsive and generative, and describe how we as teacher educators negotiated between the extremes these terms implied.
