New genomic techniques, old divides: stakeholder attitudes towards new biotechnology regulation in the EU and UK

The European Union and United Kingdom are in the process of establishing new regulation regarding the use of new genomic techniques in crop and animal breeding. As part of this process, consultations have been launched to understand the views of stakeholders and the wider public towards the use of new genomic techniques in plant and animal breeding. The responsible research and innovation framework emphasises the importance of dialogue between technology developers and stakeholders, including the public, but what are the opinions of stakeholders towards the regulation of NGTs in Europe and do they view these consultations as opportunities to engage with technology governance? We conducted semi-structured interviews with experts from a range of agri-food stakeholder groups in the European Union and United Kingdom to understand current attitudes towards new biotechnology regulation, how they viewed the process of consultation in both places and what influence they felt they had in shaping regulations. We found that the discussion is similar in both EU and UK, with predictable and fixed opinions determined by attitudes towards the perceived risks associated with direct mutagenesis. Both UK and EU consultations were considered to have the same weaknesses and stakeholders discussed a desire for more dialogic forms of engagement. We highlight several options for new forms of involvement in biotechnology regulation by exploring relevant responsible research and innovation literature.

A 30-minute nucleic acid amplification point-of-care test for genital Chlamydia trachomatis infection in women: a prospective, multi-centre study of diagnostic accuracy

BackgroundRapid Point-Of-Care Tests (POCTs) for Chlamydia trachomatis (CT) may reduce onward transmission and reproductive sexual health (RSH) sequelae by reducing turnaround times between diagnosis and treatment. The io(R) single module system (Atlas Genetics Ltd) runs clinical samples through a microfluidic CT cartridge, delivering results in 30 minutes. We evaluated its performance on female genital samples in four UK Genito-Urinary Medicine (GUM)/RSH clinics.\n\nMethodsProspective diagnostic accuracy study, using BD ProbeTec CT/GC assay as the routine clinic nucleic acid amplification test (NAAT) as the initial comparator test, and the QIAgen Artus CT assay to resolve discrepancies. In these instances, the reference standard was defined as the resolved result when two out of three assay results concurred. Female participants aged [≥]16 provided additional-to-routine self-collected vulvovaginal swabs. Samples were tested fresh with the io(R) CT assay within 7 days of collection, or were frozen at -80{degrees}C for later testing. Participant clinical, demographic and behavioural characteristics were collected to assess risk factors associated with CT infection.\n\nResultsOf 785 participants recruited, final analyses were conducted on 709 (90.3%). CT prevalence was 7.2% (51/709) overall. Sensitivity, specificity, positive and negative predictive values of the io(R) CT assay were, respectively, 96.1% (95% Confidence Interval (CI): 86.5-99.5), 97.7% (95%CI: 96.3-98.7), 76.6% (95%CI: 64.3-86.2) and 99.7% (95%CI: 98.9-100). There was no significant difference in performance measures between fresh and frozen samples, or between symptomatic and asymptomatic participants (p>0.05). The only risk factor associated with CT infection was being a sexual contact of an individual with CT.\n\nConclusionsThe io(R) CT-assay is the only 30-minute, fully automated, high-performing NAAT currently CE-marked for CT diagnosis in women, making it a highly promising diagnostic to enable specific treatment, initiation of partner notification and appropriately intensive health promotion at the point of care. Future research is required to evaluate acceptability by clinicians and patients in GUM/RSH clinics, impact on clinical pathways and patient management, and cost-effectiveness.
