ABSTRACT
BACKGROUND: Clinical research nurses and midwives (CRN/Ms) are highly specialised registered nurses. They combine their clinical nursing expertise with research knowledge and skills to aid in the delivery of rigorous, high-quality clinical research to improve health outcomes, the research participant's experience and treatment pathways ( Beer et al 2022 ). However, there is evidence that the transition into a CRN/M role is challenging for registered nurses. AIM: To discuss the development of a competency framework for CRN/Ms. DISCUSSION: The authors identified a gap in their organisation for standards that would support the development of CRN/Ms new to the role. The standards needed to be clear and accessible to use while encompassing the breadth of scope of CRN/Ms' practice. The authors used a systematic and inclusive process drawing on Benner's ( 1984 ) theory of competence development to develop a suitable framework. Stakeholders engaged in its development included research participants, inclusion agents and CRN/Ms. CONCLUSION: The project identified 15 elements that are core to the CRN/M role and the knowledge, skills and behaviours associated with it. IMPLICATIONS FOR PRACTICE: A large NHS trust has implemented the framework. It is also being shown to national and regional networks. Evaluation is under way.

Biologic therapies have transformed the management of psoriasis, but clinical outcome is variable leaving an unmet clinical need for predictive biomarkers of response. Here we perform in-depth immunomonitoring of blood immune cells of 67 patients with psoriasis, before and during therapy with the anti-TNF drug adalimumab, to identify immune mediators of clinical response and evaluate their predictive value. Enhanced NF-κBp65 phosphorylation, induced by TNF and LPS in type-2 dendritic cells (DC) before therapy, significantly correlates with lack of clinical response after 12 weeks of treatment. The heightened NF-κB activation is linked to increased DC maturation in vitro and frequency of IL-17+ T cells in the blood of non-responders before therapy. Moreover, lesional skin of non-responders contains higher numbers of dermal DC expressing the maturation marker CD83 and producing IL-23, and increased numbers of IL-17+ T cells. Finally, we identify and clinically validate LPS-induced NF-κBp65 phosphorylation before therapy as a predictive biomarker of non-response to adalimumab, with 100% sensitivity and 90.1% specificity in an independent cohort. Our study uncovers important molecular and cellular mediators underpinning adalimumab mechanisms of action in psoriasis and we propose a blood biomarker for predicting clinical outcome.

Innate lymphoid cells (ILCs) are increasingly appreciated as key regulators of tissue immunity. However, their role in human tissue homeostasis and disease remains to be fully elucidated. Here we characterize the ILCs in human skin from healthy individuals and from the inflammatory skin disease psoriasis. We show that a substantial proportion of IL-17A and IL-22 producing cells in the skin and blood of normal individuals and psoriasis patients are CD3-negative innate lymphocytes. Deep immunophenotyping of human ILC subsets showed a statistically significant increase in the frequency of circulating NKp44+ ILC3 in the blood of psoriasis patients compared with healthy individuals or atopic dermatitis patients. More than 50% of circulating NKp44+ ILC3 expressed cutaneous lymphocyte-associated antigen, indicating their potential for skin homing. Analysis of skin tissue revealed a significantly increased frequency of total ILCs in the skin compared with blood. Moreover, the frequency of NKp44+ ILC3 was significantly increased in non-lesional psoriatic skin compared with normal skin. A detailed time course of a psoriasis patient treated with anti-tumor necrosis factor showed a close association between therapeutic response, decrease in inflammatory skin lesions, and decrease of circulating NKp44+ ILC3. Overall, data from this initial observational study suggest a potential role for NKp44+ ILC3 in psoriasis pathogenesis.
