Group climate in residential youth care is considered to be essential for treatment of youth and young adults. Various instruments exist to measure quality of living group climate, but some are lengthy, use complicated wording, which make them difficult to fill out by youth and individuals with a mild intellectual disability. The present study describes the development and rationale for the Group Climate Instrument-Revised (GCI-R).

Background: Achieving meaningful consent can be challenging, particularly in contexts of diminished literacy, yet is a vital part of participant protection in global health research.

Method: We explored the challenges and potential solutions of achieving meaningful consent through a qualitative study in a predominantly hill tribe ethnic minority population in northern Thailand, a culturally distinctive population with low literacy. Semi-structured interviews were conducted with 37 respondents who had participated in scrub typhus clinical research, their family members, researchers and other key informants.

Background: In secure residential facilities, group climate perceptions of clients with mild intellectual disability or borderline intellectual functioning are systematically assessed for quality improvement. A valid and reliable measure may ensure that this process is consistent. The Group Climate Inventory-Revised (GCI-R) is a new measure to assess group climate perceptions.

Background: The Group Climate Inventory (GCI) was tested for measurement invariance across 332 adults with and 225 adults without mild intellectual disabilities in Dutch forensic treatment, and for latent mean differences on its Support, Growth, Repression, and Atmosphere subscales.

Method: Multigroup confirmatory factor analysis was used to evaluate the configural, threshold, and loading and threshold invariance of the GCI across both groups, and to compare group latent means on each subscale.

Results: Measurement invariance was found across groups.

TANK-binding kinase 1 (TBK1) is a key signalling component in the production of type-I interferons, which have essential antiviral activities, including against SARS-CoV-2. TBK1, and its homologue IκB kinase-ε (IKKε), can also induce pro-inflammatory responses that contribute to pathogen clearance. While initially protective, sustained engagement of type-I interferons is associated with damaging hyper-inflammation found in severe COVID-19 patients.

Most human killer cell immunoglobulin-like receptors (KIR) are expressed by natural killer (NK) cells and recognize HLA class I molecules as ligands. KIR3DL3 is a conserved but polymorphic inhibitory KIR recognizing a B7 family ligand, HHLA2, and is implicated for immune checkpoint targeting. The expression profile and biological function of KIR3DL3 have been somewhat elusive, so we searched extensively for KIR3DL3 transcripts, revealing highly enriched expression in γδ and CD8 T cells rather than NK cells.

Epitope-specific immunotherapies have enabled the targeted treatment of a variety of diseases, ranging from cancer, infection, and autoimmune disorders. For CD8 T cell-based therapies, the precise identification of immunogenic peptides presented by human leukocyte antigen (HLA) class I is essential which can be achieved by immunopeptidomics. Here, using lentivirus-mediated transduction and cell sorting approaches, we present a method to engineer a cell line that does not express its native HLA but instead expresses an HLA of interest (in this instance HLA-A*02:01).

Despite advances, international research ethics guidelines still tend to consist of high-level ethical principles reflecting residual influence from North American and European traditions of ethics. Local ethics committees and community advisory boards can offer more culturally-sensitive approaches to training but most institutions lack substantive practical ethics guidance to engage rich moral understandings in day-to-day research practice in diverse cultural contexts. To address this gap, we conducted an international series of qualitative research ethics case studies, linked prospectively to active research programs in diverse settings.

Background: Relationships between dynamic risk factors for externalising problem behaviour and group climate were investigated in 151 adult in-patients with mild intellectual disability or borderline intellectual functioning in a Dutch secure residential facility.

Method: Regression analysis was used to predict total group climate score and Support, Growth, Repression, and Atmosphere subscales of the 'Group Climate Inventory'. Predictor variables were Coping Skills, Attitude towards current treatment, Hostility, and Criminogenic attitudes subscales of the 'Dynamic Risk Outcome Scales'.

Despite advances in theory, often driven by feminist ethicists, research ethics struggles in practice to adequately account for and respond to the agency and autonomy of people considered vulnerable in the research context. We argue that shifts within feminist research ethics scholarship to better characterise and respond to autonomy and agency can be bolstered by further grounding in discourses from the social sciences, in work that confirms the complex nature of human agency in contexts of structural and other sources of vulnerability. We discuss some of the core concepts and critiques emerging from the literature on women and children's agency in under-resourced settings, highlighting calls to move from individualistic to relational models of agency, and to recognise the ambiguous, value-laden, and heterogeneous nature of the concept.

Background: Researchers have a responsibility to protect all participants, especially vulnerable participants, from harm. Vulnerability is increasingly understood to be context specific, yet limited guidance is available regarding the vulnerability and agency of research participants in different cultural settings. This study aims to explore research participants' daily vulnerability and agency, and how these interact with participants' research experiences in their own words.

Objective: The alliance in child and adolescent psychotherapy is widely recognized as an important factor in therapy. Studies on the alliance have increasingly focused on assessment of the alliance as a dyadic construct, measuring both client and therapist alliance ratings. However, cross-informant reports of the alliance in child psychotherapy have not yet been subjected to meta-analysis.

The aim of the present study was to examine construct validity and reliability of the German reactive proactive aggression questionnaire (RPQ) in a sample of delinquent boys ( = 156). A confirmatory factor analysis with a two-factor model of reactive and proactive aggression showed a good fit to the data. The factor structure of the original RPQ could be fully replicated in the German translation, and Cronbach's alphas were good for both subscales.

Alliance has been shown to predict treatment outcome in family-involved treatment for youth problems in several studies. However, meta-analytic research on alliance in family-involved treatment is scarce, and to date, no meta-analytic study on the alliance-outcome association in this field has paid attention to moderating variables. We included 28 studies reporting on the alliance-outcome association in 21 independent study samples of families receiving family-involved treatment for youth problems (N = 2126 families, M age youth ranging from 10.

Organic products were analysed for the presence of contaminants, microorganisms and antibiotic resistance and compared with those from conventional products. No differences were observed in the Fusarium toxins deoxynivalenol and zearalenone in organic and conventional wheat, during both a dry period and a very wet period which promoted the production of these toxins. Nitrate levels in head lettuce produced organically in the open field were much lower than those in conventional products.
