BackgroundThe presence of circulating cell-free DNA from tumours in blood (ctDNA) is of major importance to those interested in early cancer detection, as well as to those wishing to monitor tumour progression or diagnose the presence of activating mutations to guide treatment. In 2014, the UK Early Cancer Detection Consortium undertook a systematic mapping review of the literature to identify blood-based biomarkers with potential for the development of a non-invasive blood test for cancer screening, and which identified this as a major area of interest. This review builds on the mapping review to expand the ctDNA dataset to examine the best options for the detection of multiple cancer types.MethodsThe original mapping review was based on comprehensive searches of the electronic databases Medline, Embase, CINAHL, the Cochrane library, and Biosis to obtain relevant literature on blood-based biomarkers for cancer detection in humans (PROSPERO no. CRD42014010827). The abstracts for each paper were reviewed to determine whether validation data were reported, and then examined in full. Publications concentrating on monitoring of disease burden or mutations were excluded.ResultsThe search identified 94 ctDNA studies meeting the criteria for review. All but 5 studies examined one cancer type, with breast, colorectal and lung cancers representing 60% of studies. The size and design of the studies varied widely. Controls were included in 77% of publications. The largest study included 640 patients, but the median study size was 65 cases and 35 controls, and the bulk of studies (71%) included less than 100 patients. Studies either estimated cfDNA levels non-specifically or tested for cancer-specific mutations or methylation changes (the majority using PCR-based methods).ConclusionWe have systematically reviewed ctDNA blood biomarkers for the early detection of cancer. Pre-analytical, analytical, and post-analytical considerations were identified which need to be addressed before such biomarkers enter clinical practice. The value of small studies with no comparison between methods, or even the inclusion of controls is highly questionable, and larger validation studies will be required before such methods can be considered for early cancer detection.

BackgroundThe Early Cancer Detection Consortium is developing a blood-test to screen the general population for early identification of cancer, and has therefore conducted a systematic mapping review to identify blood-based biomarkers that could be used for early identification of cancer.MethodsA mapping review with a systematic approach was performed to identify biomarkers and establish their state of development. Comprehensive searches of electronic databases Medline, Embase, CINAHL, the Cochrane library and Biosis were conducted in May 2014 to obtain relevant literature on blood-based biomarkers for cancer detection in humans. Screening of retrieved titles and abstracts was performed using an iterative sifting process known as “data mining”. All blood based biomarkers, their relevant properties and characteristics, and their corresponding references were entered into an inclusive database for further scrutiny by the Consortium, and subsequent selection of biomarkers for rapid review. This systematic review is registered with PROSPERO (no. CRD42014010827).FindingsThe searches retrieved 19,724 records after duplicate removal. The data mining approach retrieved 3990 records (i.e. 20% of the original 19,724), which were considered for inclusion. A list of 814 potential blood-based biomarkers was generated from included studies. Clinical experts scrutinised the list to identify miss-classified and duplicate markers, also volunteering the names of biomarkers that may have been missed: no new markers were identified as a result. This resulted in a final list of 788 biomarkers.InterpretationThis study is the first to systematically and comprehensively map blood biomarkers for early detection of cancer. Use of this rapid systematic mapping approach found a broad range of relevant biomarkers allowing an evidence-based approach to identification of promising biomarkers for development of a blood-based cancer screening test in the general population.

Background People living with cancer face numerous psychosocial challenges, including cancer-related fatigue, fear of recurrence, and depression. There is a lack of digital interventions tailored to the needs of people living with all types of cancer. We developed a 6-week, digital, peer-delivered, self-management program: iHOPE (Help to Overcome Problems Effectively; where ‘i’ indicates the digital version of the program). The program is underpinned by positive psychology and cognitive behavioral therapy to meet these psychosocial challenges. Objective This study aimed to assess the feasibility of the iHOPE program among people living with cancer. Program adherence and satisfaction along with changes in psychological distress and positive well-being were measured. Methods A pre-post, acceptability, and feasibility design was used. People living with cancer (N=114) were recruited via a national cancer charity in the United Kingdom and were given access to the iHOPE program. Demographic and other participant characteristics were recorded. Participants completed digital measures at baseline and the end of the 6-week program for depression, anxiety, cancer-related fatigue, cancer worry or fear of cancer recurrence, positive mental well-being, hope, gratitude, and health status. The website’s system recorded data on the usage of the program. Satisfaction with the program was also measured. Results A total of 114 participants completed the baseline questionnaires. Of these, 70 people (61.4%) participated in all 6 sessions. The mean number of sessions undertaken was 5.0 (SD 1.5). Moreover, 44.7% (51/114) of participants completed at least three sessions and end-of-program outcome measures. A total of 59 participants completed the satisfaction questionnaire, where ≥90% (54/58) of participants reported that the program was easy to navigate and was well managed by the peer facilitators, and that they found the social networking tools useful. Preliminary efficacy testing among the 51 participants who completed baseline and postprogram outcome measures showed that postprogram scores decreased for depression, anxiety, cancer-related fatigue, and fear of recurrence (all P<.001) and increased for positive mental well-being (P<.001), hope (both P<.001), and gratitude (P=.02). Conclusions The feasibility evidence is promising, showing that the peer-delivered digital iHOPE program is acceptable and practical. Implementation of the iHOPE program on a wider scale will incorporate further research and development to maximize the completion rates of the measures. Initial effectiveness data suggest positive impacts on important cancer-related quality of life and mental well-being outcomes. A randomized controlled trial design with a longer follow-up is needed to confirm the potential of the iHOPE program for improving mental and physical health outcomes for cancer survivors.

The purpose of this article is to discuss the evolving workforce required to deliver quality healthcare in NHS acute care settings within the UK. The development and implementation of non-medical practitioner (NMP) roles, such as advanced clinical practitioners, surgical care practitioners, surgical first assistants, physician associates and physician assistants in anaesthesia are discussed in relation to training, regulation, governance and evaluation in clinical practice.

Background: traditional health workforce roles are changing, with existing roles being extended and advanced, while new roles are being created, often undertaking duties previously completed by doctors, sometimes referred to as non-medical practitioners (NMPs). Aim: to investigate which NMP roles exist within the UK, mapping distribution, and explore factors influencing their development and recruitment. Methods: two descriptive, exploratory, online self-completed semi-structured questionnaires were used. One was sent to all NHS acute healthcare providers (n=156) and private/independent healthcare providers in England (n=90). A separate questionnaire collected data, using convenience and snowballing approaches, from NMPs across the UK. Quantitative data were analysed using descriptive and frequency statistics. Qualitative data derived from open questions and comments were analysed using content and thematic analysis. Results: healthcare organisations in England returned 23/246 useable questionnaires; 115 NMPs returned responses, 19 did not meet the criteria, leaving 96 useable responses. Conclusion: seven NMP roles were identified, throughout the UK, with regional variation. Several factors influence the development and recruitment of NMP roles in England such as service delivery and national policies. Inconsistencies were noted in Agenda for Change pay banding. Many practitioners undertook NMP roles to progress their career clinically.

2018) Evaluation of an intervention to increase clinician knowledge and confidence to support breastfeeding, kangaroo care and positive touch within neonatal units. AbstractBreastfeeding and kangaroo care rates in neonatal units across the United Kingdom vary despite evidence for the clinical benefits. Clinicians have reported a need for evidence-based training to support parents with these practices. The aim of this study was to evaluate the Small Wonders Change Programme (SWCP), an intervention that aims to increase clinician knowledge and confidence to support parents in neonatal units to undertake breastfeeding and kangaroo care. Two neonatal intensive care units participated and 47 clinicians completed the Neonatal Unit Assessment Tool (NUCAT) pre and post-intervention. 18 of these clinicians also participated in a semi-structured interview to further explore the impact of the intervention on clinician's practice. Both clinician knowledge (t(46)=4.61, p<=0.000) and confidence (pre t(46)=4.82, p<.000) significantly increased following the intervention. Analysis of the interviews revealed that clinicians directly attributed subsequent individual and unit-wide change in practice to an increase in knowledge and confidence as a result of the intervention. This study suggests that a clinician focussed intervention can lead to positive changes in clinician confidence, knowledge and practice in supporting parents to undertake breastfeeding and kangaroo care in neonatal units.
