Self-monitoring of blood glucose in insulin-treated diabetes: a multicase study

Objective To explore how and why self-monitoring of blood glucose (SMBG) is carried out in a real-world context. Research design and methods We conducted a multicase study among ten people with type 1 and insulin-treated type 2 diabetes mellitus in Scotland, alongside seven nominated support people and four healthcare professionals. All participants were interviewed in depth and six participants provided SMBG diaries. Stones' version of structuration theory informed the analysis. Results People with diabetes were able to provide immediate motives for SMBG at particular times, often having different motives on different occasions. We identified six such motives, including routine, in response to symptoms, associated with a diabetes review, to facilitate lifestyle, when a 'good' result was expected, and higher level motives for longer term glycemic control. These motives were influenced by underlying attitudes toward diabetes that included level of engagement and responsibility for diabetes, a desire not to be controlled by diabetes, resistance to diabetes, diabetes education and relationship with the health service, fear of hypoglycemia, and prevention of diabetes complications. Five responses to test results were identified, depending on the immediate motive and underlying attitudes. Conclusions People with insulin-treated diabetes do not necessarily self-monitor with an explicit goal of improving long-term glycemic control, but may have other motives that are important to them. An individualized understanding is therefore needed to advise people with diabetes how SMBG can be optimized for them

Health and health behaviours among a cohort of first year nursing students in Scotland: A self-report survey

The study aim was to collect data on the health and health-related behaviours of undergraduate nursing students at a Higher Education Institution in Scotland, to identify the need for potential health behaviour change interventions as part of their undergraduate course. An anonymous self-report questionnaire (with questions about physical activity, diet, sleep, alcohol, smoking, mental health) was administered to first year nursing students at a Scottish university. The response rate was 88%, with 207 respondents (26 male, 178 female, 3 other). Age ranged from 16 to 45 years (mean 24.5 years). Overall, 48 (23.1%) students rated their physical health as excellent/very good, and 100 (48.3%) their mental health as such. 157 (76.2%) students were achieving 150 min of physical activity per week. There were 48 (29%) and 30 (18.2%) overweight and obese students respectively. 129 (62.6%) students viewed a mobile device for > 30 min before sleep. 176 (86.3%) students consumed alcohol, with 32 (15.4%) reporting binge drinking. The prevalence of current smoking was 24.8%. The students’ health behaviour profile was therefore broadly similar to that of the general population in Scotland, but smoking, diet, sleep practices and binge-drinking were identified as priority areas for health education and intervention

The development of an intervention for diabetes prevention among people with impaired glucose regulation:feasibility and acceptability of an intervention component

Background As part of the design process of a low-cost minimal-contact diabetes prevention intervention, we issued a blood glucose meter to people with impaired glucose regulation (who are at high risk of type 2 diabetes). We conducted a feasibility study to assess the acceptability of this intervention component and whether and how recipients engaged with it. Methods A blood glucose meter was given to 19 people identified through primary care, who were asked to use the meter in an exploratory way during a 4-week trial period, to try to understand the effect of different foods on the body. They were advised that they could test as often or as little as they liked and were also asked to keep a food/exercise diary for at least 1 week. They were interviewed about their experiences afterwards. Results There was a high level of engagement with testing, with the total number of tests recorded ranging from 11 to 114 (median 74) among 18 participants. Fifteen participants tested almost every day during the 4-week period. The cognitive engagement was more limited. All participants commented on their own results, and most were able to relate high or low results to foods eaten and exercise taken, usually in response to prompting. However, there was limited thought or understanding beyond this in terms of longer-term patterns of diet and exercise, and testing was routine rather than experimental. Some participants were confused by conflicting or unexpected results. A few minor problems were reported by participants, such as soreness, inconvenience, and difficulty in getting blood, but never enough to discontinue testing. Several participants stated that the meter was a useful aid as a reminder that they were at high risk of diabetes and served as a prompt that needed to make and/or maintain behaviour changes. Conclusions The study suggests that blood glucose monitoring is acceptable to people with impaired glucose regulation and that they would engage with it as part of an intervention to improve their diet. The study has also uncovered potential mechanisms of action for behaviour change

The Sun as a planet-host star : proxies from SDO images for HARPS radial-velocity variations

JL acknowledges support from NASA Origins of the Solar System grant No. NNX13AH79G and from STFC grant ST/M001296/1.The Sun is the only star whose surface can be directly resolved at high resolution, and therefore constitutes an excellent test case to explore the physical origin of stellar radial-velocity (RV) variability. We present HARPS observations of sunlight scattered off the bright asteroid 4/Vesta, from which we deduced the Sun's activity-driven RV variations. In parallel, the Helioseismic and Magnetic Imager instrument on board the Solar Dynamics Observatory provided us with simultaneous high spatial resolution magnetograms, Dopplergrams and continuum images of the Sun in the Fe i 6173 Å line. We determine the RV modulation arising from the suppression of granular blueshift in magnetized regions and the flux imbalance induced by dark spots and bright faculae. The rms velocity amplitudes of these contributions are 2.40 and 0.41 m s−1, respectively, which confirms that the inhibition of convection is the dominant source of activity-induced RV variations at play, in accordance with previous studies. We find the Doppler imbalances of spot and plage regions to be only weakly anticorrelated. Light curves can thus only give incomplete predictions of convective blueshift suppression. We must instead seek proxies that track the plage coverage on the visible stellar hemisphere directly. The chromospheric flux index R′HK derived from the HARPS spectra performs poorly in this respect, possibly because of the differences in limb brightening/darkening in the chromosphere and photosphere. We also find that the activity-driven RV variations of the Sun are strongly correlated with its full-disc magnetic flux density, which may become a useful proxy for activity-related RV noise.PostprintPeer reviewe

How does the self-reported health of undergraduate nursing students change during their degree programme? Survey results from a Scottish University

Background The lifestyle behaviours, and the physical and mental health of nurses, are poorer than those of other allied health professionals, and of the general population. However, these were no less favourable among first year undergraduate nursing students at a Scottish Higher Education Institution (HEI) than among similar people of the same age. We compared health and health behaviours among the same cohort of undergraduate nursing students over the course of their degree. Methods An anonymous self-complete repeat cross-sectional survey was administered during a timetabled teaching session at three time-points to undergraduate nursing students at the start of Years 1, 2 and 3 of their programme. They had received written information about the study previously. Results Self-reported health did not change significantly over time, but there was a clear decline over the 3 years in the proportions of students rating their mental health as excellent/very good/good and a concomitant increase in those rating their mental health as fair/poor. Correspondingly, the mean WEMWBS wellbeing score declined over the 3 years, with the proportion of students with a score of less than 46 (indicating either high risk of major depression, or in high risk of psychological distress and increased risk of depression) increasing from one quarter to one half. This effect was captured and described using a Bayesian regression analysis. The most noticeable change in health behaviours was a decline in physical activity levels over the study period. The proportion of students managing 150 min of weekly physical activity decreased from three quarters to two thirds. This was reflected in higher self-reported sedentary time, although there were no observable trends over time in mean BMI, or proportions of students categorised as overweight or obese. Conclusions: This paper suggests that there may be a decline in mental health and in participation in physical activity among nursing students over the course of their degree. We recommend the incorporation of an intervention into the undergraduate nursing curriculum that promotes and encourages regular physical activity, offering students the opportunity to learn about health promotion and lifestyle change in practice, to improve their own physical health, and to address mental wellbeing

Analysis of spontaneous, user-generated data about gestational diabetes on online forums: implications for diabetes prevention

Aims To explore the experiences and perceptions of gestational diabetes mellitus reported by women within online parental‐support forums and, specifically, to analyse what women say about a diagnosis of gestational diabetes, their future risk of type 2 diabetes, and lifestyle behaviour for management of gestational diabetes and prevention of type 2 diabetes. Methods The discussion boards of two parenting websites (Mumsnet and Netmums) were searched using the search term 'gestational diabetes or GD' in February 2019. Relevant posts made by users with gestational diabetes on or after 1 January 2017 were retained for analysis. Framework analysis using pre‐existing framework from a previous study was used to organize and analyse the data. Results A total of 646 posts generated by 282 unique users were included in the analysis. Analysis of the online content identified three important implicit messages that may be being conveyed to readers. The first is that gestational diabetes is not a serious diagnosis that warrants undue concern. Secondly, few users recognized the importance of their own behaviours or lifestyle, with others minimizing personal responsibility or attributing gestational diabetes to non‐modifiable factors. Finally, there was a lack of acknowledgment of heightened risk of type 2 diabetes. These three messages will all directly mitigate against the efforts of clinicians (and others) to encourage women with gestational diabetes to improve their lifestyle behaviours in the longer term. Conclusions These findings highlight messages that are being widely disseminated and that are unlikely to support prevention of type 2 diabetes

Postpartum opportunistic advice in primary care for women who have had gestational diabetes: a qualitative study of health care professionals' views

Background Women who have had gestational diabetes during pregnancy are at very high risk of developing type 2 diabetes later in life, but their understanding of the risks is often limited. In this study we explored the views of health care professionals regarding offering brief opportunistic advice to women after their pregnancy, during unrelated consultations in primary care, relating to reducing diabetes risk. Methods The study took place in three Health Boards in Scotland. We conducted semi-structured one-to-one interviews (either face-to-face or telephone) with two health visitors, three practice nurses, two GPs, two diabetes consultants and two obstetricians. A focus group with five health visitors was also held. A topic guide was followed, covering the feasibility and acceptability of delivering brief opportunistic advice during a routine consultation, the optimal way to identify and recall women with previous gestational diabetes, and the possible content and timing of any such intervention. A thematic approach was used to analyse the qualitative data generated. Results The interviews/discussion lasted from 15 to 51 min. There was widespread support from all participants for offering opportunistic advice, and general consensus that health visitors would be best placed to do this as part of the Universal Health Visiting Pathway in Scotland. Thematic analysis generated three significant points of discussion: implications for training of health visitors, the need for a systematic approach to identifying women with gestational diabetes, and the optimal timing of delivery. Despite an already demanding schedule of providing advice and education to women, health visitors were confident that they could offer educational advice, provided that they received appropriate training to do so. However, there would need to be a watertight system for identifying women in their care who had had gestational diabetes. In terms of timing, later visits around 6–8 months after delivery were considered most suitable. Conclusions There is support from health care professionals, and most pertinently from health visitors, that the frequency of routine visits with women during the Universal Health Visiting Pathway programme in Scotland provides potential opportunities for education around future diabetes risk to women who have had gestational diabetes

Feasibility of trial procedures for a randomised controlled trial of a community based group exercise intervention for falls prevention for visually impaired older people: the VIOLET study

Background Visually impaired older people (VIOP) have a higher risk of falling than their sighted peers, and are likely to avoid physical activity. The aim was to adapt the existing Falls Management Exercise (FaME) programme for VIOP, delivered in the community, and to investigate the feasibility of conducting a definitive randomised controlled trial (RCT) of this adapted intervention. Methods Two-centre randomised mixed methods pilot trial and economic evaluation of the adapted group-based FaME programme for VIOP versus usual care. A one hour exercise programme ran weekly over 12 weeks at the study sites (Newcastle and Glasgow), delivered by third sector (voluntary and community) organisations. Participants were advised to exercise at home for an additional two hours over the week. Those randomised to the usual activities group received no intervention. Outcome measures were completed at baseline, 12 and 24 weeks. The potential primary outcome was the Short Form Falls Efficacy Scale – International (SFES-I). Participants’ adherence was assessed by reviewing attendance records and self-reported compliance to the home exercises. Adherence with the course content (fidelity) by instructors was assessed by a researcher. Adverse events were collected in a weekly phone call. Results Eighteen participants, drawn from community-living VIOP were screened; 68 met the inclusion criteria; 64 participants were randomised with 33 allocated to the intervention and 31 to the usual activities arm. 94% of participants provided data at the 12 week visit and 92% at 24 weeks. Adherence was high. The intervention was found to be safe with 76% attending nine or more classes. Median time for home exercise was 50 min per week. There was little or no evidence that fear of falling, balance and falls risk, physical activity, emotional, attitudinal or quality of life outcomes differed between trial arms at follow-up. Conclusions The intervention, FaME, was implemented successfully for VIOP and all progression criteria for a main trial were met. The lack of difference between groups on fear of falling was unsurprising given it was a pilot study but there may have been other contributory factors including suboptimal exercise dose and apparent low risk of falls in participants. These issues need addressing for a future trial

The Winter Camp of the Viking Great Army, AD 872–3, Torksey, Lincolnshire

This paper presents the results of a multidisciplinary project that has revealed the location, extent and character of the winter camp of the Viking Great Army at Torksey, Lincolnshire, of AD 872–3. The camp lay within a naturally defended area of higher ground, partially surrounded by marshes and bordered by the River Trent on its western side. It is considerably larger than the Viking camp of 873–4 previously excavated at Repton, Derbyshire, and lacks the earthwork defences identified there. Several thousand individuals overwintered in the camp, including warriors, craftworkers and merchants. An exceptionally large and rich metalwork assemblage was deposited during the Great Army’s overwintering, and metal processing and trading was undertaken. There is no evidence for a pre-existing Anglo-Saxon trading site here; the site appears to have been chosen for its strategic location and its access to resources. In the wake of the overwintering, Torksey developed as an important Anglo-Saxon borough with a major wheel-thrown pottery industry and multiple churches and cemeteries. The Torksey evidence allows for a radical reappraisal of the character of Viking winter camps, and the legacy of the Viking Great Army for Anglo-Saxon England
