Youth suicide risk and mental health post-COVID: An Australian perspective

Aims: Suicide is a leading cause of death for young people, and rates in Australia are increasing. The Australian city of Melbourne faced the toughest COVID-19 pandemic lockdown restrictions worldwide, which had a major impact on youth mental health. This study aimed to provide a snapshot into the mental health and suicide-related thoughts and behaviours of Australian Adolescents from Melbourne post the lockdowns. Method(s): Participants were 932 young people (Age M = 15.5, 53% female) recruited from high schools in Melbourne, Australia as part of a larger RCT. Participants completed measures of suicidal ideation (SIDAS) and behaviour (recent attempts and current plans), and depressive symptoms (PHQ-9). Result(s): Preliminary results indicate that 28% of participants experienced some level of suicidal ideation with 7% reporting severe suicidal ideation. Suicide attempts in the sample in the last 12 months (13%) and current plans (3%) were less common but still prevalent. In terms of depressive symptoms, the breakdown in the sample was 5% severe, 8% moderately severe, 18% moderate, 25% mild and 43% none to minimal with 1% not reporting. Data related to particular risk factors (e.g., years since the pandemic, gender, school etc.) along with implications for practice and policy will be presented at the conference. Conclusion(s): This study sheds light on the mental health and suiciderelated thoughts and behaviours of school-attending young people following COVID-19-related lockdowns in Australia. The high levels of suicidality and poor mental health in the cohort point to a need for targeted interventions and support for this group.

Pandemic preparedness of diagnostic radiographers during COVID-19: A scoping review.

INTRODUCTION: As chest imaging is a tool for detecting coronavirus disease 2019 (COVID-19), diagnostic radiographers are a key component of the frontline workforce. Due to its unforeseen nature, COVID-19 has challenged radiographers' preparedness in combating its effects. Despite its importance, literature specifically investigating radiographers' readiness is limited. However, the documented experiences are prognostic of pandemic preparedness. Hence, this study aimed to map this literature by addressing the question: 'what does the existing literature reveal about the pandemic preparedness of diagnostic radiographers during COVID-19?'. METHODS: Using Arksey and O'Malley's framework, this scoping review searched for empirical studies in MEDLINE, Embase, Scopus, and CINAHL. Consequently, 970 studies were yielded and underwent processes of deduplication, title and abstract screening, full-text screening, and backward citation searching. Forty-three articles were deemed eligible for data extraction and analysis. RESULTS: Four themes that reflected pandemic preparedness were extrapolated: infection control and prevention, knowledge and education, clinical workflow, and mental health. Notably, the findings highlighted pronounced trends in adaptation of infection protocols, adequate infection knowledge, and pandemic-related fears. However, inconsistencies in the provision of personal protective equipment, training, and psychological support were revealed. CONCLUSION: Literature suggests that radiographers are equipped with infection knowledge, but the changing work arrangements and varied availability of training and protective equipment weakens their preparedness. The disparate access to resources facilitated uncertainty, affecting radiographers' mental health. IMPLICATIONS FOR PRACTICE: By reiterating the current strengths and weaknesses in pandemic preparedness, the findings can guide clinical practice and future research to correct inadequacies in infrastructure, education, and mental health support for radiographers in the current and future disease outbreaks.

Measuring effective teaching components of school-based agricultural education teaching aspirants during the COVID-19 pandemic

Defining, identifying, and evaluating teaching effectiveness is a difficult proposition;however, measuring the effectiveness of school-based agricultural education (SBAE) teachers is even more difficult considering the diversity of programs nationwide. Faculty in the agricultural education teacher preparation program at Oklahoma State University sought to measure the effective characteristics developed during the Spring 2020 semester, using the effective teaching model as a frame for this study in conjunction with the Effective Teaching Instrument for SBAE Teachers (ETI-SBAE). This approach allowed the research team an opportunity to further investigate the preparedness of SBAE teacher aspirants during the ongoing COVID-19 pandemic. A descriptive research design was implemented with SBAE teacher aspirants at Oklahoma State University with a junior- or senior-level classification (N = 72). The SBAE pre-service teachers at Oklahoma State University identified a high sense of effectiveness based on the ETI-SBAE instrument. In this group of pre-service teachers, all participants scored an overall teaching effectiveness score of strong to very strong, with the overwhelming majority (79.2%) planning to enter the teaching profession. Additionally, there was a relationship between intention to teach and teaching effectiveness scores, with those who intend to teach reporting higher teaching effectiveness scores. The ETI-SBAE holds utility for SBAE teacher preparation programs.

Soybean science challenge: growing soybean education beyond our borders

The Soybean Science Challenge (SSC) continues to support Arkansas STEM (science, technology, engineering, and mathematics) educational goals. It aligns with the Next Generation Science Standards (NGSS). Junior high and high-school students are engaged in active learning and the co-creation of knowledge through the support of classroom-based lessons and applied student research. The SSC educates and engages junior high and high school science students and teachers in 'real-world' Arkansas-specific soybean science education through an original NGSS-aligned curriculum in 7E and GRC-3D format and a continuum of educational methods, which include: teacher workshops, online and virtual live stream education, virtual NGSS aligned mini-lessons for the science classroom, community gardens, personal mentoring, student-led research and corresponding award recognition, and partnerships with state and national educators, agencies and the popular media. The COVID19 global pandemic continued to alter the educational landscape in 2021, despite increased in-person instruction. The Soybean Science Challenge (SSC), by nature of its existing design and methodology, launched online Next Generation Science Standards (NGSS) aligned Gathering Reasoning and Communicating (GRC)-3D and 7E lesson plans for teachers. An online course was added, including NGSS-aligned mini-lesson videos for the science classroom, and additional virtual field trips were added to the list on the Soybean Science Challenge website. The Challenge also sponsored the Arkansas Science Teacher Association Conference in October 2021, and the SSC Coordinator Diedre Young conducted a workshop on bringing agriculturally based lessons into the science classroom. The Soybean Science Challenge was also active in science fairs across the state, judging participants at both the regional and state levels. The SSC is in its second year of the junior level award at regional science fairs. Through the SSC, teachers now have access to a plethora of educational instructions that bring real-world agricultural critical thinking into the classroom and students' homes. The SSC has learned that not only do Arkansas teachers and students benefit from these additional resources but teachers and students from other states benefit as well. In 2021, the SSC program reached over 3,000 students and teachers through in-person, digital, virtual, and print methods.

Transfusing convalescent plasma as post-exposure prophylaxis against SARS-CoV-2 infection: a double-blinded, phase 2 randomized, controlled trial.

BACKGROUND: The efficacy of SARS-CoV-2 convalescent plasma (CCP) for preventing infection in exposed, uninfected individuals is unknown. CCP might prevent infection when administered before symptoms or laboratory evidence of infection. METHODS: This double-blinded, phase 2 randomized, controlled trial (RCT) compared the efficacy and safety of prophylactic high titer (≥1:320 by Euroimmun ELISA) CCP with standard plasma. Asymptomatic participants aged ≥18 years with close contact exposure to a person with confirmed COVID-19 in the previous 120 hours and negative SARS-CoV-2 test within 24 hours before transfusion were eligible. The primary outcome was new SARS-CoV-2 infection. RESULTS: 180 participants were enrolled; 87 were assigned to CCP and 93 to control plasma, and 170 transfused at 19 sites across the United States from June 2020 to March 2021. Two were excluded for screening SARS-CoV-2 RT-PCR positivity. Of the remaining 168 participants, 12/81 (14·8%) CCP and 13/87 (14·9%) control recipients developed SARS-CoV-2 infection; 6 (7·4%) CCP and 7 (8%) control recipients developed COVID-19 (infection with symptoms). There were no COVID-19-related hospitalizations in CCP and 2 in control recipients. Efficacy by restricted mean infection free time (RMIFT) by 28 days for all SARS-CoV-2 infections (25·3 vs. 25·2 days; p = 0·49) and COVID-19 (26·3 vs. 25·9 days; p = 0·35) was similar for both groups. CONCLUSIONS: Administration of high-titer CCP as post-exposure prophylaxis, while appearing safe, did not prevent SARS-CoV-2 infection.

Digital Pathology Training Effectiveness for the Evaluation of Pd-L1 Expression in Multiple Tumor Indications

Background In-person pathologist trainings during the COVID- 19 pandemic became impossible, necessitating a shift to remote-digital whole slide image (WSI) training. High concordance between WSI and glass slide scores from the same specimens stained with PD-L1 IHC 22C3 pharmDx (SK006) across multiple tumor indications supported the validity of digital training.1 However, in-person microscope (glass-slide) training versus remote-digital (WSI) training effectiveness must be assessed. Collated testing data on specimens (SK006 stained) spanning multiple indications scored by external pathologists during Agilent led training and testing (T&T) sessions via glass slides were compared to sessions utilizing WSIs. Methods Stained slides (30 unique specimens per tumor indication) were scanned on an Aperio AT2 scanner to generate WSIs for digital T&T. Remote T&T sessions used WebEx and PathcoreScholar's online platform to discuss scoring guidelines and WSI training cases. Subsequently, external pathologists evaluated WSIs in PathcoreScholar for PD-L1 expression using either Tumor Proportion Score (TPS) or Combined Positive Score (CPS) scoring algorithms and interpreted these scores at predefined cutoffs (figure 1). In both glass and WSI scoring test modalities, passing is defined as inter and intra-observer overall agreement (OA) >=85%. Training effectiveness pass rates from glass slide data (2018-2020) and WSI data (2021- 2022) spanning multiple indications and scoring algorithms were calculated and then compared using the Fisher-Freeman- Halton test, with a significance threshold of 0.05. Only data from initial pathologist tests were included in the pass rate calculation;data from re-tests executed after initial test failure were excluded. Results The differences between pass rates for microscope (glass slide) and digital (WSI) testing were not statistically significant (p-value > 0.05) (tables 1 and 2). Testing pass rates for indications scored with TPS or CPS using microscope glass slide vs digital WSI T&T was not statistically significant (pvalue > 0.05) (table 3). Conclusions No statistically significant differences in pathologist training effectiveness for PD-L1 were observed between remote and in-person trainings across multiple tumor indications, scoring algorithms, and cutoffs. These results demonstrate the effectiveness and equivalency of remote-digital pathologist trainings for evaluation of PD-L1 expression as detected by PD-L1 IHC 22C3 pharmDx in multiple tumor indications when compared to in-person-microscope glass slide T&T. Use of digital training and scoring proficiency testing can provide pathologists around the world with access to high-quality, interactive training from leading experts in PD-L1 expression evaluation.

JOBS, JUSTICE, AND THE GREEN NEW DEAL

An effective Green New Deal (GND) must be bold, transformative and implemented at an unprecedented scale. While iterations of the GND have existed for years and have been gaining traction in the public policy arena, governments and policy makers have generally been slow to link job growth to climate change, particularly when it concerns economic justice. Yet a justice-oriented GND offers a clear pathway forward that includes retraining for energy sector workers, jobs for underrepresented populations, investments in other sectors beyond renewable energy, such as care work, health care, education and housing. This chapter examines the possibilities of a combined GND/COVID-19 recovery plan that prioritizes economic and climate justice by focusing on creating decent, well-paying jobs in low- or zero-carbon sectors of the economy. I offer a five-point plan for a just and inclusive GND that uses the COVID-19 pandemic recovery as a catalyst to unite the concerns of climate activists with social and economic justice activists. The plan includes investing in renewable energy and retraining workers, expanding the care economy and sustainable housing, supporting the rights of Indigenous Peoples and their jurisdiction over traditional lands and working in partnership with social movements around the world to ensure a radically better, more sustainable and more equitable world. © 2023 selection and editorial matter, Kyla Tienhaara and Joanna Robinson;individual chapters, the contributors.

Construction of a passive sulfate treatment system

The paper reports on the third phase of constructing a passive sulfate reduction system with sulfur sequestering. The tiered approach included bench- and pilot-scale systems to prove the feasibility of using a passive treatment solution. This included the use of a biochemical reactor (BCR) with different proportions of wood chips, straw, manure, limestone, and biochar to culture sulfate-reducing bacteria. In addition, the concept of using a fixed-bed anaerobic bioreactor (FBAR), where alcohol was added to enhance the sulfate reducer activity, was also tested. In total, three BCRs and two FBARs were set up for this stage of the assessment. The resulting treated leachate was then passed through different media types to remove sulfur species generated by the bacteria, with an aerobic wetland used to polish the effluent. The success of the bench-scale (Tier 1) project led to a pilot-scale system (Tier 2) being constructed and monitored in spring 2020, the results of which confirmed the success of the bench-scale testing and provided useful insights into management of the system, particularly in winter months. The COVID crisis has had its impact, but the system has operated continuously and ran through 2021. This led to planning permission being awarded for the project, which enabled Tier 3 construction in late 2022/early 2023. © 2022 Australian Centre for Geomechanics, Perth.
