A randomised control crossover trial of a theory based intervention to improve sun-safe and healthy behaviours in construction workers:Study protocol

Abstract Background Exposure to sunlight can have both positive and negative health impacts. Excessive exposure to ultra-violet (UV) radiation from the sun can cause skin cancer, however insufficient exposure to sunlight has a detrimental effect on production of Vitamin D. In the construction industry there are onsite proactive behaviours for safety, but sun-safety remains a low priority. There is limited research on understanding the barriers to adopting sun-safe behaviours and the association this may have with Vitamin D production. This paper reports a protocol for an intervention study, using text messaging in combination with a supportive smartphone App. The intervention aims to both reduce UV exposure during months with higher UV levels and promote appropriate dietary changes to boost Vitamin D levels during months with low UV levels. Method/design Approximately 60 construction workers will be recruited across the United Kingdom. A randomised control crossover trial (RCCT) will be used to test the intervention, with randomisation at site level – i.e. participants will receive both the control (no text messages or supportive App support) and intervention (daily text messages and supportive App). Using the Theory of Planned Behaviour (TPB) the intervention focuses on supporting sun-safety and healthy dietary decisions in relation to Vitamin D intake. The intervention emphasises cultivating the perception of normative support in the workplace, increasing awareness of control and self-efficacy in taking sun-protective behaviours, making healthier eating choices to boost Vitamin D, and tackling stigmas attached to image and group norms. Each study epoch will last 21 days with intervention text messages delivered on workdays only. The supportive App will provide supplementary information about sun protective behaviours and healthy dietary choices. The primary outcome measure is 25-hydroxy-Vitamin D [25(OH)D] level (obtained using blood spot sampling), which will be taken pre and post control and intervention periods. Secondary outcome measures are two-fold, (1) using the TPB to detect changes in behaviour, and (2) quantifying UV exposure during the UK peak radiation season (April–September) using body-mounted UV sensors. Discussion This study will provide important information about the effectiveness of a technology-based intervention to promote sun-safety and healthy behaviours in outdoor construction workers.

Multiple novel prostate cancer susceptibility signals identified by fine-mapping of known risk loci among Europeans

Genome-wide association studies (GWAS) have identified numerous common prostate cancer (PrCa) susceptibility loci. We have fine-mapped 64 GWAS regions known at the conclusion of the iCOGS study using large-scale genotyping and imputation in 25 723 PrCa cases and 26 274 controls of European ancestry. We detected evidence for multiple independent signals at 16 regions, 12 of which contained additional newly identified significant associations. A single signal comprising a spectrum of correlated variation was observed at 39 regions; 35 of which are now described by a novel more significantly associated lead SNP, while the originally reported variant remained as the lead SNP only in 4 regions. We also confirmed two association signals in Europeans that had been previously reported only in East-Asian GWAS. Based on statistical evidence and linkage disequilibrium (LD) structure, we have curated and narrowed down the list of the most likely candidate causal variants for each region. Functional annotation using data from ENCODE filtered for PrCa cell lines and eQTL analysis demonstrated significant enrichment for overlap with bio-features within this set. By incorporating the novel risk variants identified here alongside the refined data for existing association signals, we estimate that these loci now explain ∼38.9% of the familial relative risk of PrCa, an 8.9% improvement over the previously reported GWAS tag SNPs. This suggests that a significant fraction of the heritability of PrCa may have been hidden during the discovery phase of GWAS, in particular due to the presence of multiple independent signals within the same regio

The Essential Elements of a Risk Governance Framework for Current and Future Nanotechnologies

Societies worldwide are investing considerable resources into the safe development and use of nanomaterials. Although each of these protective efforts is crucial for governing the risks of nanomaterials, they are insufficient in isolation. What is missing is a more integrative governance approach that goes beyond legislation. Development of this approach must b

Teaching reluctant students: using the principles and techniques of motivational interviewing to foster better student-teacher interactions

In formal learning settings there will always be instances of resistance to learning from students, resulting in either open conflict or withdrawal and consequent disillusionment on the part of both students and teachers. This paper presents a set of principles and associated practices for responding to disengagment from learning in constructive ways. This framework, motivational interviewing, is borrowed from healthcare but has been adapted for use in higher education. The model focuses on building confidence and independence and fostering engagement, thus enabling students to take responsibility for their learning. The model is student-centred and collaborative and thus fosters constructive relationships between student and teacher. This paper presents the theoretical underpinnings of the model and the ways in which it can be used in teacher-student interactions

Children and young people's uses of the internet for homework

This article extends current research by more closely examining children and young people’s uses of the Internet for homework support within the familial context. In particular, it examines how young people find and deploy resources, how levels and quality of access influence use and the participation of other family members in homework support. It argues that whilst families view the Internet as a useful resource for homework, there are pitfalls which centre on the relatively high cost of home access in the UK. In some families, these costs may impact negatively on the affordances of the Internet for supporting homework and learning the functional skills and competencies needed to use the Internet autonomously

General practice training and virtual communities of practice - a review of the literature

<p>Abstract</p> <p>Background</p> <p>Good General Practice is essential for an effective health system. Good General Practice training is essential to sustain the workforce, however training for General Practice can be hampered by a number of pressures, including professional, structural and social isolation. General Practice trainees may be under more pressure than fully registered General Practitioners, and yet isolation can lead doctors to reduce hours and move away from rural practice. Virtual communities of practice (VCoPs) in business have been shown to be effective in improving knowledge sharing, thus reducing professional and structural isolation. This literature review will critically examine the current evidence relevant to virtual communities of practice in General Practice training, identify evidence-based principles that might guide their construction and suggest further avenues for research.</p> <p>Methods</p> <p>Major online databases <it>Scopus</it>, <it>Psychlit</it> and <it>Pubmed</it> were searched for the terms “Community of Practice” (CoP) AND (Online OR Virtual OR Electronic) AND (health OR healthcare OR medicine OR “Allied Health”). Only peer-reviewed journal articles in English were selected. A total of 76 articles were identified, with 23 meeting the inclusion criteria. There were no studies on CoP or VCoP in General Practice training. The review was structured using a framework of six themes for establishing communities of practice, derived from a key study from the business literature. This framework has been used to analyse the literature to determine whether similar themes are present in the health literature and to identify evidence in support of virtual communities of practice for General Practice training.</p> <p>Results</p> <p>The framework developed by Probst is mirrored in the health literature, albeit with some variations. In particular the roles of facilitator or moderator and leader whilst overlapping, are different. VCoPs are usually collaborations between stakeholders rather than single company VCoPs. Specific goals are important, but in specialised health fields sometimes less important than in business. Boundary spanning can involve the interactions of different professional groups, as well as using external experts seen in business VCoPs. There was less use of measurement in health VCoPs. Environments must be supportive as well as risk free. Additional findings were that ease of use of technology is paramount and it is desirable for VCoPs to blend online and face-to-face involvement.</p> <p>Conclusions</p> <p>The business themes of leadership, sponsorship, objectives and goals, boundary spanning, risk-free environment and measurements become, in the health literature, facilitation, champion and support, objectives and goals, a broad church, supportive environment, measurement benchmarking and feedback, and technology and community.</p> <p>General Practice training is under pressure from isolation and virtual communities of practice may be a way of overcoming isolation. The health literature supports, with some variation, the business CoP framework developed by Probst. Further research is needed to clarify whether this framework is an effective method of health VCoP development and if these VCoPs overcome isolation and thus improve rural retention of General Practice registrars.</p
