'Far right just means anyone who wants to support British values': Mobilizing 'British values' talk in discussions of the August 2024 UK race riots.

Sambaraju R et al. · Jul 1, 2026

Social psychological research has shown how far-right leaders mobilize people by claiming that majority populations are threatened or silenced. This paper builds on this work to examine a related process in naturalistic interactions: how riotous actions are explained and justified through appeals to 'British values' in online forums. Using discursive psychology, we analyse talk surrounding the riots that followed the stabbing of three young girls in Southport, England-the UK race riots of August 2024. We show that invoking British or English values serves two key functions: it renders rioters' actions self-explanatory and offers a competing account of rioters as the more authentic representation of Britishness and the British people than the government. This reframing of 'British values' offers up a challenge to those attributing riots to 'far right' motivations and instead portrays the riots as effortful and even ideal expressions of British citizenship. Thus, British values operate not merely as symbols but as rhetorical tools that can sanitize the 'far-right' label linking the riots, immigration, state policy and national identity.

pr2-Wormifier: A Bioinformatics Pipeline to Create Custom Reference Databases for Improved Metabarcoding of Marine Protists.

Knell S et al. · Jul 1, 2026

Metabarcoding of environmental and ancient environmental DNA (eDNA and sedaDNA) is a powerful approach for studying and monitoring marine communities. However, its effectiveness is limited by the availability of comprehensive and well-curated reference databases, particularly for protists. Here, we introduce pr2-wormifier, a bioinformatics pipeline designed to create customized and improved reference databases for 18S rRNA-based metabarcoding. This pipeline integrates sequences from PR 2 and NCBI with taxonomic information from the World Register of Marine Species (WoRMS) and AlgaeBase, allowing for refined taxonomic assignments at the genus and species levels. pr2-wormifier enables users to tailor reference databases to specific taxonomic groups or geographic regions, enhancing the resolution and accuracy of biodiversity assessments. We benchmarked the pipeline using a sedimentary ancient DNA dataset from the Baltic Sea, focusing on marine protists, especially ciliates and dinoflagellates. The customized database generated by pr2-wormifier identified more sequences at the genus and species levels than PR 2 alone, while maintaining taxonomic consistency and quality. Our results demonstrate that pr2-wormifier addresses common limitations of existing databases, such as low taxonomic resolution and missing taxa and facilitates more reliable classification in metabarcoding studies. By enabling the creation of locally relevant, taxonomically curated databases, pr2-wormifier offers a flexible and scalable solution for improving the identification of protists in environmental and paleoenvironmental research.

Hearing Loss in Adults With Diabetes and Prediabetes: A Systematic Review and Meta-Analysis.

Nisar M et al. · Jul 1, 2026

Diabetes impairs hearing through microvascular damage and neuropathy, yet the prevalence of moderate-to-severe hearing loss (≥ 40 dB HL) remains inadequately explored. Variations by age, diabetes duration, and socioeconomic factors are inadequately characterised. This systematic review quantified the prevalence and comparative risk of moderate-to-severe hearing loss in diabetes and prediabetes, exploring variations across age, national income level, and disease duration. We searched PubMed, Scopus, Web of Science, SPORTDiscus, and CINAHL (2000-2025) for observational studies reporting audiometric thresholds in diabetic or prediabetic subjects (PROSPERO: CRD42018100742). Quality was assessed using the Newcastle-Ottawa Scale. Random-effects meta-analyses generated pooled prevalence and odds ratios (ORs) with 95% confidence intervals (CIs). Publication bias was evaluated via funnel plots and Egger's regression. Of 3490 records, 29 studies qualified. Most examined type 2 diabetes; one included prediabetes. Twenty-three studies (n = 5221) yielded a pooled prevalence of 24% (95% CI: 19%-30%; I 2 = 94%). Eleven studies showed diabetes doubled hearing loss odds versus controls (OR = 2.41, 95% CI: 1.62-3.60; I 2 = 86.6%). Risk was significantly elevated in younger adults (< 60 years: OR = 3.03, 95% CI: 2.17-4.22) but not in older adults (≥ 60 years: OR = 1.52, 95% CI: 0.72-3.22). Low- and middle-income countries showed the highest risk (OR = 4.51, 95% CI: 2.43-8.40) versus high-income countries (OR = 1.78, 95% CI: 1.05-3.02). Diabetes duration < 10 years conferred elevated risk (OR = 2.68). Small-study effects were detected (Egger's p = 0.019) but sensitivity analyses confirmed robustness. One in four diabetic adults has clinically significant hearing loss, particularly in younger individuals and resource-limited populations. These findings support the integration of routine audiometric screening into diabetes care.

Oestrogen receptor phosphorylation profiles and in silico PAM50 subtyping reflect sexual dimorphism in breast cancer.

Chatterji S et al. · Jul 1, 2026

Breast cancer (BC) is most prevalent in females but also accounts for <1% of male cancer cases and 0.2% of male cancer-related deaths. Distribution of histological subtypes, receptor status, and age of diagnosis varies based on sex, and a growing body of evidence supports sex-specific molecular differences in BC. However, this is limited by the smaller number of male cases available for study compared to the thousands of cases of female BC. We combined publicly available male BC gene expression datasets for 195 patients from 4 studies and split randomly into discovery and validation sets. Clustering and gene expression analysis were performed. Two stable clusters were identified initially, confirmed in the validation set. Cluster C1 was enriched for genes associated with MAPK signalling and arylesterase activity. Cluster C2 showed enrichment of genes associated with proliferation, invasion, and metastasis, along with enrichment of gene ontology and pathway terms related to ECM regulation, particularly collagen-containing ECM. Of note, when stratified by ERα and PR status, no enrichment was observed with the predicted PAM50 classification. ERα and MAPK signalling were enriched in both clusters, albeit through different gene sets. Since these pathways were enriched, we investigated the signalling regulation of ERα based on immunohistochemical expression of phosphorylated ERα (S104, S118, S167, S294) and their prognostic roles. This analysis also revealed distinctions from female BC, showing a lack of prognostic outcome for any of these biomarkers. We show that male BC does not align with female BC in the same way that intrinsic subtypes of female BC are not identical. As BC heterogeneity is well recognised, we propose that male BC should be considered as a potentially unique clinical subtype of BC.

Maintaining Health in Later Life: Perspectives of Older Indian Migrants in Melbourne, Australia.

Sandhu S et al. · Jul 1, 2026

Issues addressed Little is known about how older migrants maintain their health, despite health promotion's emphasis on strengthening everyday capacities for well-being. Older Indian migrants are one of Australia's fastest-growing ageing populations, yet existing research has focused predominantly on barriers, disease management and service access. As a result, the health-promoting strategies older migrants already use remain largely invisible in policy and practice. This study addresses this gap by exploring the practices that older Indian migrants in Melbourne employ to maintain their health. Methods A qualitative study was conducted using semi-structured individual and focus group interviews with 55 India-born adults aged 50+ (32 temporary and 23 permanent migrants) living in Melbourne, Australia. Interviews were undertaken in English, Hindi and Punjabi. Results Participants identified interconnected practices underpinning everyday health maintenance, including reliance on home remedies; culturally familiar yet adaptive dietary and physical activity routines, including walking; domestic labour and group activities. Community and family networks facilitated motivation and support, while gendered household roles constrained women's capacity for rest and engagement in structured physical activity. Conclusion This study found that older Indian migrants sustain health through home remedies, culturally embedded dietary routines, physical activity and a strong social network. These practices reflect a strengths-based orientation to well-being, drawing on intergenerational knowledge and community support to maintain health in later life. So what Health-promotion strategies should work with, rather than replace, the culturally grounded practices older Indian migrants already use. Culturally considerate, family-centred health advice; intergenerational activities and digital media partnerships may enhance healthy ageing.

An Aging Clock Based on Immune Repertoire Features: COVID-19 Accelerates Aging.

Gao X et al. · Jul 1, 2026

Aging induces immunosenescence, a progressive decline in immune function underpinning age-related pathogen vulnerability, yet T/B cell receptor (TCR/BCR) repertoire remodeling during aging remains incompletely characterized, especially in non-European populations. Additionally, SARS-CoV-2 may perturb immune homeostasis and accelerate aging, but its impact on immune repertoire aging is unclear. Here, we analyzed leukocyte DNA from 195 healthy Chinese individuals (25-93 years) and 94 post-COVID-19 cases via CDR3 high-throughput sequencing. Aging correlated with shorter CDR3 sequences, reduced VDJ gene/V-J combination diversity, declining TCR/BCR clonotype counts (179.7/507 per 3 years), expanded hyperexpanded TCR/large BCR clones, and reduced diversity (critical turning point ~60 years). These changes were intensified post-COVID-19, with altered amino acid usage, diminished diversity, and expanded SARS-CoV-2/Mycobacterium tuberculosis-related clones. We developed a LightGBM-based immune repertoire aging clock, validating accelerated biological aging (increased cAgeDiff) and reduced intrinsic capacity in post-COVID-19 individuals. Our findings reveal age-dependent immune repertoire remodeling exacerbated by COVID-19, deepening understanding of immunosenescence and post-viral dysfunction, with potential clinical applications for age-related immune decline and post-COVID-19 syndromes.

Parental Perspectives and Experiences of Working With Speech and Language Therapists to Support Home Practice for Their Child With a Speech Sound Disorder: A Qualitative Study.

Pritchard K et al. · Jul 1, 2026

Background Speech sound disorder (SSD) is broadly defined as difficulty producing speech sounds in childhood. It can have a lasting impact on academic outcomes and well-being, making effective early intervention vital. Speech and language therapists (SLTs) consider parental involvement-particularly supporting their child with home practice-as essential to a child's progress. Relationships between SLTs and parents are known to facilitate this engagement. However, there is a significant gap in the literature regarding parents' perspectives, and little is known about what parents perceive to be most effective in supporting home practice. Understanding these perspectives is crucial for designing interventions that are both feasible and meaningful for families. Aim To explore the perspectives of parents of children with SSD aged ≤5;11, about their experiences with speech and language therapy intervention sessions and home practice. Methods and procedures This study used qualitative methodology. Nine parents, recruited via social media, professional networks and a university clinic, participated in focus groups or 1:1 interviews. A group of children, aged 4-6, who had lived experience of SSD, speech and language therapy and home practice were consulted to design the topic guide and inform data analysis. Discussions were recorded, transcribed verbatim and analysed using Reflexive Thematic Analysis. Outcomes and results Four main themes were constructed as follows: (1) Building positive therapeutic relationships is fundamental to families' experiences and creates the foundation for successful home practice. (2) SLTs need to employ a wide range of skills and knowledge, including a multi-modal approach to empower parents and develop their capability. (3) Clear communication is key for shared power, understanding of roles, active involvement and effective home practice. (4) Factors outside an individual's control can impact parents' attitudes towards, and engagement with, home practice. Conclusions and implications We conclude that relationships between SLTs and parents, and the skills required to build these, underpin parental motivation to engage in home practice. To maximise parental capability, SLTs ensure that parents understand not only what to do but why they are doing it, utilising a variety of methods. Whilst some barriers for home practice are out of the SLT's control, using all opportunities to develop the motivation and capability of the parents is required. To achieve this, service delivery models may need to be reconsidered. What this paper adds What is already known on this subject SSD that persists into school years can have lasting implications for a child's academic outcomes and well-being. Effective and efficient early intervention is essential. SLTs and parents agree that working together, including parental delivery of home practice, is important for a child's progress. Little is known about how parents experience and perceive what SLTs do within intervention sessions to ensure parents feel confident and capable of delivering effective home practice. What this paper adds to existing knowledge This is the first study to explore parents' perceptions and experiences of what SLTs do within direct intervention sessions for young children with SSD and how this supports parents to become implementors of intervention for their child at home. Findings suggest that parents benefit from SLTs using a range of teaching and coaching approaches, including clear instructions and active involvement, to ensure parents feel confident and capable at home. Relationships between the parent, SLT and the child are highly valued by parents, and are fundamental for parental engagement with home practice. What are the potential or actual clinical implications of this work? SLTs prioritising building effective relationships with parents and children can support parental motivation for home practice. SLTs can work with parents to increase opportunities for home practice by building it into their daily lives, including working with other family members. To maximise parental capability, it is important to ensure that parents understand not only what to do but why they are doing it, utilising a variety of methods. To achieve this, service delivery models may need to be reconsidered.

Traditional Fermented Dairy Products as Reservoirs of Bifidobacterium With Probiotic Potential: From Microbial Diversity to Functional Characterization.

Habiba MU et al. · Jul 1, 2026

Traditional fermented dairy products (TFDPs) are complex microbial ecosystems that may serve as reservoirs of many microorganisms, including those with probiotic potential such as Bifidobacterium species and lactobacilli. Although bifidobacteria are widely used as probiotic microorganisms in defined formulations, their occurrence, persistence, and functional relevance within TFDPs remain incompletely understood. This review critically synthesizes current evidence on the diversity, ecological roles, and traits associated with probiotic potential of Bifidobacterium spp. detected in TFDPs, including raw-milk fermentations, artisanal dairy products, and selected controlled dairy systems. Species such as Bifidobacterium animalis, Bifidobacterium longum, Bifidobacterium bifidum, and Bifidobacterium breve have been reported across yogurt, kefir, airag (traditional Mongolian fermented dairy beverage from mare milk), and raw milk cheeses, often at low abundance or as transient microbial community members. Many isolates from fermented dairy products exhibit traits commonly associated with probiotic functionality, including acid/bile tolerance, adhesion capacity, exopolysaccharide production, and antimicrobial activity. However, most reports remain limited to presence/absence or in vitro assays, with limited in vivo or clinical validation. Advances in molecular and omics-based approaches have improved detection, characterization, and safety evaluation; however, translation into validated applications remains constrained by challenges in isolation, viability, and strain-level confirmation. Importantly, detection of bifidobacteria in TFDPs does not confer probiotic status, which requires strain-level identification, demonstrated safety, adequate viable counts at consumption, and clinical evidence of health benefit. Collectively, TFDPs, as culturally embedded microbial reservoirs, may support the discovery of novel bifidobacterial strains for future development of functional foods or probiotic products following rigorous validation.

Serotype Characterization and Transmission Modelling of Foot-and-Mouth Disease in Dairy Farms, Bishoftu, Ethiopia.

Fetene E et al. · Jul 1, 2026

Background Foot-and-mouth disease (FMD) is among the most important transboundary animal diseases, causing widespread economic losses due to decreased productivity, trade restrictions, and costly disease management efforts. Objectives This study aimed to characterize circulating FMDV serotypes and quantify within-farm transmission dynamics during active outbreaks in Bishoftu, Ethiopia. Methods Five epithelial tissue and 39 oral swab samples were collected from 11 dairy farms experiencing active FMD outbreaks. Samples were tested using quantitative reverse transcriptase polymerase chain reaction (RT-qPCR) and antigen-capturing enzyme-linked immunosorbent assay (ELISA) for FMDV detection and serotyping. A susceptible-infected-recovered (SIR) model was fitted to outbreak data to quantify transmission dynamics. Results Out of 44 samples, 37 (84.1%) were positive for FMDV using RT-qPCR, and 23 (52.3%) were positive by ELISA. Serotypes O, SAT-1, and SAT-2 were identified, with SAT-2 being predominant. Transmission modelling indicated an average transmission rate (λ) of 0.82 and a recovery rate (γ) of 0.32 per day, corresponding to a mean basic reproductive number (R 0 ) of 3.7. The trivalent vaccine demonstrated low effectiveness (31% against single serotypes; 26% when adjusted for mixed infections), which was insufficient to achieve herd immunity given the high transmission intensity. Conclusions These findings demonstrate that vaccination alone cannot control FMD in these systems. Control requires improved vaccine matching and the combination of vaccination with enhanced biosecurity measures, such as animal isolation and movement control.

Knowing How to Ask About Digital Culture in Youth Mental Health Care: A Co-Designed Tool.

Paquin V et al. · Jul 1, 2026

Background With the digital cultures that youth are exposed to and participating in come potential risks and protective factors for their mental health. However, despite clear need there is a lack of guidance to help mental health professionals evaluate the role of social media, artificial intelligence, and other technologies in young people's mental health. Aims To co-design with young people the Digital Culture Interview, an interview tool to support the clinical assessment of digital cultural factors in mental health care. Method We recruited a diverse group of 12 participants aged 16-35 years (mean age 22 years) from outpatient mental health clinics in Montreal, Canada. Using the nominal group technique, they identified topics they found most relevant for exploring in a clinical assessment the experiences and practices involving digital technologies. Based on the topics that received the most votes from participants, we co-developed a list of interview questions and written guidance for their administration. Results Participants identified and ranked 48 themes. Drawing from these, 14 questions were developed for inclusion in the Digital Culture Interview, covering four topics: identity and worldview, negative experiences online, coping, and understanding of mental health. Participants emphasised that exploring digital culture in mental health care requires patients' trust and a baseline of knowledge. If done sensitively, this may enhance the patient-clinician alliance and improve mutual understanding. Conclusions The Digital Culture Interview has the potential to enhance rapport and reveal risk and protective factors that are salient to and actionable in mental health care.
