    Abstract Objective This study aims to improve foundation doctors' knowledge of guidelines for confirming nasogastric (NG) tube position and to enhance their confidence and competency in NG tube placement. Methods A three-part educational approach was designed, which included an educational leaflet and allowed the assessment of a participant's knowledge of guidelines pertaining to NG tube positioning before and after education. This educational leaflet and accompanying pre- and post-learning assessments were distributed among NHS Foundation Trusts in the UK between January 2022 and June 2022. All participants were foundation doctors in the UK. Those who had entered further training after the completion of their foundation training, at the time of assessment distribution, were excluded. Results A total of 173 participants completed this assessment. We found a significant increase in confidence among participants following the education (p<0.05). There was also a significant improvement in objective knowledge of guidelines on NG tube position confirmation following education (p<0.05). Conclusions Current knowledge on NG tube positioning is lacking among foundation doctors, but this can be significantly improved with simple educational leaflets. Furthermore, many participants felt that more training is needed, and this topic should be included in an essential teaching program.

    Abstract Delta-like non-canonical Notch ligand 1 (DLK1) is a cleavable single-pass transmembrane protein and a member of the Notch/Delta/Serrate family. It is paternally expressed and belongs to a group of imprinted genes located on chromosome band 14q32 in humans and 12qF1 in mice. DLK1 is expressed in many human tissues during embryonic development but in adults expression is low and is mostly restricted to (neuro)endocrine tissues and other immature stem/progenitor cells (notably hepatoblasts). However, DLK1 is expressed at a high frequency in many common malignancies (liver, breast, brain, pancreas, colon and lung). More recently, high levels of expression have been identified in endocrine-related cancers such as ovarian and adrenocortical carcinoma. There is growing evidence that DLK1 expression in cancer is associated with worse prognosis and that DLK1 may be a marker of cancer stem cells. Although the exact mechanism through which DLK1 functions is not fully understood, it is known to maintain cells in an undifferentiated phenotype and has oncogenic properties. These effects are partly exacted through interaction with the Notch signalling pathway. In this review, we have detailed the functional role of DLK1 within physiology and malignancy and posited a mechanism for how it exacts its oncogenic effects. In describing the expression of DLK1 in cancer and in healthy tissue, we have highlighted the potential for its use both as a biomarker and as a potential therapeutic target.
