Co-creating and implementing a novel pre-conference event to promote equity and inclusivity among academic researchers and people who use drugs.

This commentary draws on our experience organising a targeted networking event at the 10th International Conference on Health and Hepatitis in Substance Users, in Glasgow, Scotland in October 2022. The event, held the day before the conference, brought together people with lived and living experiences of drug use and early- and mid-career researchers on an equitable basis. We offer reflections, focussing on how the event promoted community-academic engagement from members of the respective groups. We provide recommendations for how conferences can organise to engage with people who use drugs-both those with lived and living experience and foster greater inclusion for all attendees.

2020-2021 field seasons of Maize GxE project within the Genomes to Fields Initiative.

OBJECTIVES: This release note describes the Maize GxE project datasets within the Genomes to Fields (G2F) Initiative. The Maize GxE project aims to understand genotype by environment (GxE) interactions and use the information collected to improve resource allocation efficiency and increase genotype predictability and stability, particularly in scenarios of variable environmental patterns. Hybrids and inbreds are evaluated across multiple environments and phenotypic, genotypic, environmental, and metadata information are made publicly available. DATA DESCRIPTION: The datasets include phenotypic data of the hybrids and inbreds evaluated in 30 locations across the US and one location in Germany in 2020 and 2021, soil and climatic measurements and metadata information for all environments (combination of year and location), ReadMe, and description files for each data type. A set of common hybrids is present in each environment to connect with previous evaluations. Each environment had a collaborator responsible for collecting and submitting the data, the GxE coordination team combined all the collected information and removed obvious erroneous data. Collaborators received the combined data to use, verify and declare that the data generated in their own environments was accurate. Combined data is released to the public with minimal filtering to maintain fidelity to the original data.

A peer-delivered intervention to reduce harm and improve the well-being of homeless people with problem substance use: the SHARPS feasibility mixed-methods study.

BACKGROUND: For people experiencing homelessness and problem substance use, access to appropriate services can be challenging. There is evidence that development of trusting relationships with non-judgemental staff can facilitate service engagement. Peer-delivered approaches show particular promise, but the evidence base is still developing. This study tested the feasibility and acceptability of a peer-delivered intervention, through 'Peer Navigators', to support people who are homeless with problem substance use to address a range of health and social issues. OBJECTIVES: The study objectives were to design and implement a peer-delivered, relational intervention to reduce harms and improve health/well-being, quality of life and social functioning for people experiencing homelessness and problem substance use, and to conduct a concurrent process evaluation to inform a future randomised controlled trial. DESIGN: A mixed-methods feasibility study with concurrent process evaluation was conducted, involving qualitative interviews [staff interviews (one time point), n = 12; Peer Navigator interviews (three or four time points), n = 15; intervention participant interviews: first time point, n = 24, and second time point, n = 10], observations and quantitative outcome measures. SETTING: The intervention was delivered in three outreach services for people who are homeless in Scotland, and three Salvation Army hostels in England; there were two standard care settings: an outreach service in Scotland and a hostel in England. PARTICIPANTS: Participants were people experiencing homelessness and problem substance use (n = 68) (intervention). INTERVENTION: This was a peer-delivered, relational intervention drawing on principles of psychologically informed environments, with Peer Navigators providing practical and emotional support. MAIN OUTCOME MEASURES: Outcomes relating to participants' substance use, participants' physical and mental health needs, and the quality of Peer Navigator relationships were measured via a 'holistic health check', with six questionnaires completed at two time points: a specially created sociodemographic, health and housing status questionnaire; the Patient Health Questionnaire-9 items plus the Generalised Anxiety Disorder-7; the Maudsley Addiction Profile; the Substance Use Recovery Evaluator; the RAND Corporation Short Form survey-36 items; and the Consultation and Relational Empathy Measure. RESULTS: The Supporting Harm Reduction through Peer Support (SHARPS) study was found to be acceptable to, and feasible for, intervention participants, staff and Peer Navigators. Among participants, there was reduced drug use and an increase in the number of prescriptions for opioid substitution therapy. There were reductions in risky injecting practice and risky sexual behaviour. Participants reported improvements to service engagement and felt more equipped to access services on their own. The lived experience of the Peer Navigators was highlighted as particularly helpful, enabling the development of trusting, authentic and meaningful relationships. The relationship with the Peer Navigator was measured as excellent at baseline and follow-up. Some challenges were experienced in relation to the 'fit' of the intervention within some settings and will inform future studies. LIMITATIONS: Some participants did not complete the outcome measures, or did not complete both sets, meaning that we do not have baseline and/or follow-up data for all. The standard care data sample sizes make comparison between settings limited. CONCLUSIONS: A randomised controlled trial is recommended to assess the effectiveness of the Peer Navigator intervention. FUTURE WORK: A definitive cluster randomised controlled trial should particularly consider setting selection, outcomes and quantitative data collection instruments. TRIAL REGISTRATION: This trial is registered as ISRCTN15900054. FUNDING: This project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 26, No. 14.

People who are homeless have worse physical and mental health, and higher rates of drug/alcohol (substance) use, than the general population. For people experiencing these challenges, completely stopping the use of substances can be difficult. Harm reduction services can be useful in reducing risks. Approaches delivered by people who have had similar experiences (peers) are also promising. Some research has highlighted the importance of trusting relationships with service staff. More research is needed on how all of these should work with people who are homeless and who use substances. This study consisted of four 'Peer Navigators' providing practical and emotional support to a group of people who are homeless and use substances to help improve their quality of life and health. The Peer Navigators had similar past experiences. The Peer Navigators were hired, and worked with around 15 'participants' each, for 2­12 months. They were based in third-sector homelessness residential and outreach services in Scotland and England. The Peer Navigators developed relationships with participants. They worked with (and often accompanied) them to access services, such as substance use treatment, health care, housing and welfare/benefits. The Peer Navigators had access to a small budget to pay for essentials, including food and bus fares. The relationship between the Peer Navigators and participants was most important, so the Peer Navigators spent time getting to know and listening to them. The aim was to understand if this intervention could be delivered to individuals experiencing these challenges. This study was not designed to know if the intervention worked; a larger study is needed for that. Despite some challenges, the participants were able to make positive changes to their lives, and they valued working with their Peer Navigator. The Peer Navigators enjoyed their roles and staff generally supported the intervention. The next step is to conduct more research to assess if this intervention can make a difference.

Genetic diversity assessment of Georgia peanut cultivars developed during ninety years of breeding.

The cultivated peanut(Arachis hypogaea L.) has experienced severe genetic bottlenecks over the course of its evolution and domestication. Most genetic diversity studies in peanut have focused on global genetic stocks, wild accessions, and related species, but few have focused on elite cultivars. The objective of this project was to assess the genetic diversity of 32 peanut cultivars developed by the University of Georgia breeding program since its inception in 1931. Quantifying genetic similarity (GSIM) among these cultivars will provide a better understanding of their relationships and aid in breeding for cultivar development. Genotyping-by-sequencing (GBS), in concert with the recently published A. hypogaea genome sequence, was used to identify a total of 27,142 single nucleotide polymorphisms (SNPs) among these cultivars. Coefficients of parentage (CoP) were calculated based on publicly available pedigree information and compared with SNP-based GSIM estimates; the resulting correlations were low, ranging from R2 = 0.212-0.279. Although genetic diversity is generally low in cultivated peanut, our data indicate that the genetic diversity of Georgia cultivars has actually increased since the early days of the breeding program, likely a result of the incorporation of diverse germplasm and breeding lines into the program. The results reported here provide a valuable understanding of genetic variation among elite Georgia peanut cultivars that have had a significant impact on the peanut industry within the United States.
