Non-medical prescribing policy in the United Kingdom National Health Service: systematic review and narrative synthesis

Abstract

Non-medical prescribing was introduced into the United Kingdom (UK) to improve patient care, through extending healthcare professionals roles. More recent government health service policy focuses on the increased demand and the need for efficiency. This systematic review aimed to describe any changes in government policy position and the role that non-medical prescribing plays in healthcare provision.\n\nThe systematic review and narrative analysis included policy and consultation documents that describe independent non-medical prescribing. A pre-defined protocol was registered with PROSPERO (CRD42015019786). Professional body websites, other relevant websites and the following databases were searched to identify relevant papers: HMIC, Lexis Nexis, UK Government Web Archive, UKOP, UK Parliamentary Papers and Web of Science. Papers published between 2006 and February 2018 were included.\n\nFollowing exclusions, 45 papers were selected for review; 23 relating to policy or strategy and 22 to consultations. Of the former, 13/23 were published 2006-2010 and the remainder since 2013. Two main themes are identified: chronological aspects and healthcare provision. The impact of government change and associated major healthcare service reorganisation resulted in the publication gap for policy documents. The role of non-medical prescribing has evolved to support efficient service delivery, and cost reduction. For many professions, prescribing appears embedded into practice; however, pharmacy continues to produce policy documents, suggesting that prescribing is not yet perceived as normal practice.\n\nPrescribing appears to be more easily adopted into practice where it can form part of the overall care of the patient. Where new roles are required to be established, then prescribing takes longer to be universally adopted. While this research concerns policy and practice in the UK, this aspect of role adoption has wider potential implications.

Lipid-ASO therapeutics exhibit differential tissue targeted delivery upon systemic or local CNS administration

Antisense oligonucleotides (ASOs) are a powerful therapeutic modality, but their full potential is hindered by pharmacokinetic properties that affect tissue and cellular delivery. Lipid conjugation is increasingly used to modulate ASO's biodistribution and promote extrahepatic activity, yet lipid dependent effects on in vivo functional delivery, particularly in the central nervous system (CNS), remain less explored. Here, we performed a side by side in vivo comparison of cholesterol, palmitic acid (C16:0), docosanoic acid (C22:0), and eicosapentaenoic acid (C20:5) conjugated to a fully phosphorothioated 3 10 3 LNA gapmer ASO targeting the Malat1 long non coding RNA. Lipid-ASO conjugates were administered systemically or locally in the brain of mice and evaluated for tissue level and cellular level distribution by imaging, qPCR and single-cell RNA sequencing, simultaneously annotating cell origin and global transcriptional changes within the cell. Following systemic administration in mice, lipid conjugation improved overall multi organ efficacy compared to unconjugated ASO, but with pronounced tissue specific differences. Single cell sequencing of liver and heart transcriptomes revealed lipid dependent cellular uptake patterns and transcriptional responses distinct from administration of unconjugated ASO. After intracerebroventricular administration, selected fatty acid conjugates enhanced silencing in deep brain regions such as the striatum, whereas cholesterol conjugation impaired functional delivery despite increased CNS retention. Light-sheet microscopy showed restricted parenchymal penetration of cholesterol ASOs compared with broader but heterogeneous distribution of palmitic acid conjugate. Together, these findings demonstrate that lipid identity critically determines ASO efficacy, productive cellular uptake, and regional CNS engagement, emphasizing the need for context specific lipid design in ASO therapeutic development.

Novel Dissymmetric Ionizable Lipid-Assembled Lipid Nanoparticles for Delivery of Ferroptosis-Related siRNA in Diabetic Treatment

Small interfering RNA (siRNA) enables precise post-transcriptional gene silencing for refractory diseases, yet its clinical translation remains limited by the lack of safe and efficient delivery vectors. Inspired by the dissymmetric alkyl chain architecture of natural membrane phospholipids, we designed and synthesized 34 novel ionizable lipids with dissymmetric hydrophobic tails and formulated them into lipid nanoparticles (LNPs). Through systematic physicochemical and biological assessments, we established clear structure-activity relationships and identified two lead LNPs (O14-LNP, H18a-LNP) with superior endosomal escape capacity, enhanced in vivo gene silencing potency, and favorable biosafety relative to the clinical benchmark MC3-LNP. In both streptozotocin-induced and spontaneous db/db type 2 diabetes (T2D) mouse models, lead LNPs delivering ferroptosis-related siRNAs effectively ameliorated glucose and lipid metabolic disorders, restored islet function, and alleviated hepatic steatosis. This study not only lays a theoretical foundation for the rational design of novel ionizable lipids, but also validates the therapeutic potential of siRNA therapy targeting ferroptosis, providing a versatile delivery platform and targeted therapeutic strategy for the treatment of T2D.

Accelerating Inflammation Resolution to Counteract Chemical Cutaneous Injury

Chemical exposure to vesicants such as sulfur mustard (SM), and electrophilic riot control agents such as 2-chlorobenzalmalononitrile (CS) tear gas agent, cause strong cutaneous inflammation. Classical anti-inflammatory treatments have focused on interference with target initiation and maintenance of inflammation, with mixed outcomes. Inflammation is broadly classified into three temporal phases, initiation, amplification and maintenance, and resolution. Resolution of inflammation was thought to be a passive process but the recent body of literature shows that resolution is an active process and is mediated by fatty acid-derived mediators (specialized pro-resolving mediators, SPMs). We hypothesized that accelerating resolution phase of inflammation may attenuate the exaggerated inflammatory response following chemical threat exposure, leading to decreased morbidity and improved recovery. In this study, SPMs, such as Resolvin D1 (RvD1) and Resolvin D2 (RvD2), were administered to mice at nanogram doses post-exposure to an SM analog, 2-chloroethyl-ethyl-sulfide (CEES) or CS tear gas agent. SPMs decreased edema (ear thickness and punch biopsy weights), pro-inflammatory cytokines (IL-1{beta}, CXCL1/KC, MIP2) and protease marker (MMP-9), and vascular leakage (determined by IRDye 800 CW PEG) while improving histopathology in cutaneous chemical injury mouse models. These results support our hypothesis and pave the way for SPMs for further development as potential medical countermeasures for chemical threat agents-induced skin injuries.
