Breaking Free from Smoking: A Novel Digital Smoking Cessation Intervention for Offenders in UK Prisons
Introduction: The level of smoking cessation support across UK prisons is variable, with most offering pharmacological support, such as nicotine replacement therapy. However, with a complete smoking ban in prisons in England now imminent, additional standardised behavioural support is necessary to help offenders go smoke-free. Aims: This study used the Behaviour Change Wheel to aim to develop the content of an online smoking cessation intervention for offenders, with consideration of their capability, motivation and opportunity for behaviour change. Methods: This was an intervention development study. The Behaviour Change Wheel was used to map cognitive, behavioural, physiological and social targets for the intervention, onto appropriate intervention techniques for inclusion in the smoking cessation programme for offenders. Results: Psychological capability, social opportunity and reflective and automatic motivation were identified through deductive thematic analysis as areas of change required to achieve smoking cessation. A total of 27 behavioural change techniques were chosen for this smoking cessation intervention and were mapped onto the Lifestyle Balance Model which provided the theoretical basis on which the components of the programme are conceptualised. This included strategies around increasing motivation to quit, anticipating smoking triggers, modifying smoking-related thoughts, regulating emotions, managing cravings, replacing smoking and rewarding nicotine abstinence and adopting a healthier lifestyle. Conclusions: Through the utilisation of the Behaviour Change Wheel, the development process of this digital smoking cessation intervention was achieved. Further research is planned to evaluate the clinical effectiveness of this intervention and to explore how the programme is implemented in practice within prison settings
Oral supplementation of healthy adults with 2'-O-fucosyllactose and lacto-N-neotetraose is well tolerated and shifts the intestinal microbiota
The gut microbiota has been established as an important player influencing many aspects of human physiology. Breast milk, the first diet for an infant, contains human milk oligosaccharides (HMO) that shape the infant's gut microbiota by selectively stimulating the growth of specific bacteria, especially bifidobacteria. In addition to their bifidogenic activity, the ability of HMO to modulate immune function and the gut barrier makes them prime candidates to restore a beneficial microbiota in dysbiotic adults and provide health benefits. We conducted a parallel, double-blind, randomised, placebo-controlled, HMO-supplementation study in 100 healthy, adult volunteers, consuming chemically produced 2'-O-fucosyllactose (2'FL) and/or lacto-N-neotetraose (LNnT) at various daily doses and mixes or placebo for 2 weeks. All participants completed the study without premature discontinuation. Supplementation of 2'FL and LNnT at daily doses up to 20 g was shown to be safe and well tolerated, as assessed using the gastrointestinal symptoms rating scale. 16S rRNA sequencing analysis showed that HMO supplementation specifically modified the adult gut microbiota with the primary impact being substantial increases in relative abundance of Actinobacteria and Bifidobacterium in particular and a reduction in relative abundance of Firmicutes and Proteobacteria. This study provides the first set of data on safety, tolerance and impact of HMO on the adult gut microbiota. Collectively, the results from this study show that supplementing the diet with HMO is a valuable strategy to shape the human gut microbiota and specifically promote the growth of beneficial bifidobacteria
What can eye-tracking tell us?
Background: Early development of neurocognitive functions in infants can be compromised by poverty, malnutrition and lack of adequate stimulation. Optimal management of neurodevelopmental problems in infants requires assessment tools that can be used early in life, and are objective and applicable across economic, cultural and educational settings. Objective and design: The present study examined the feasibility of infrared eye tracking as a novel and highly automated technique for assessing visual-orienting and sequence-learning abilities as well as attention to facial expressions in young (9-month-old) infants. Techniques piloted in a high-resource laboratory setting in Finland (N=39) were subsequently field-tested in a community health centre in rural Malawi (N=40). Results: Parents' perception of the acceptability of the method (Finland 95%, Malawi 92%) and percentages of infants completing the whole eye-tracking test (Finland 95%, Malawi 90%) were high, and percentages of valid test trials (Finland 69-85%, Malawi 68-73%) satisfactory at both sites. Test completion rates were slightly higher for eye tracking (90%) than traditional observational tests (87%) in Malawi. The predicted response pattern indicative of specific cognitive function was replicated in Malawi, but Malawian infants exhibited lower response rates and slower processing speed across tasks. Conclusions: High test completion rates and the replication of the predicted test patterns in a novel environment in Malawi support the feasibility of eye tracking as a technique for assessing infant development in low-resource setting. Further research is needed to the test-retest stability and predictive validity of the eye-tracking scores in low-income settings
