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

Genomic surveillance of 4CMenB vaccine antigenic variants among disease-causing Neisseria meningitidis isolates, United Kingdom, 2010–2016

In September 2015, 4CMenB meningococcal vaccine was introduced into the United Kingdom infant immunization program without phase 3 trial information. Understanding the effect of this program requires enhanced surveillance of invasive meningococcal disease (IMD) Neisseria meningitidis isolates and comparison with prevaccination isolates. Bexsero Antigen Sequence Types (BASTs) were used to analyze whole-genome sequences of 3,073 prevaccine IMD N. meningitidis isolates obtained during 2010−2016. Isolates exhibited 803 BASTs among 31 clonal complexes. Frequencies of antigen peptide variants were factor H binding protein 1, 13.4%; Neisserial heparin-binding antigen 2, 13.8%; Neisseria adhesin A 8, 0.8%; and Porin A-VR2:P1.4,10.9%. In 2015−16, serogroup B isolates showed the highest proportion (35.7%) of exact matches to >1 Bexsero components. Serogroup W isolates showed the highest proportion (93.9%) of putatively cross-reactive variants of Bexsero antigens. Results highlighted the likely role of cross-reactive antigens. BAST surveillance of meningococcal whole-genome sequence data is rapid, scalable, and portable and enables international comparisons of isolates

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

The Changing Face of Water: A Dynamic Reflection of Antibiotic Resistance Across Landscapes

Little is known about the role of surface water in the propagation of antibiotic resistance (AR), or the relationship between AR and water quality declines. While healthcare and agricultural sectors are considered the main contributors to AR dissemination, few studies have been conducted in their absence. Using linear models and Bayesian kriging, we evaluate AR among Escherichia coli water isolates collected bimonthly from the Chobe River in Northern Botswana (n = 1997, n = 414 water samples; July 2011–May 2012) in relation to water quality dynamics (E. coli, fecal coliform, and total suspended solids), land use, season, and AR in wildlife and humans within this system. No commercial agricultural or large medical facilities exist within this region. Here, we identify widespread AR in surface water, with land use and season significant predicators of AR levels. Mean AR was significantly higher in the wet season than the dry season (p = 0.003), and highest in the urban landscape (2.15, SD = 0.098) than the protected landscape (1.39, SD = 0.051). In-water E. coli concentrations were significantly positively associated with mean AR in the wet season (p < 0.001) but not in the dry season (p = 0.110), with TSS negatively associated with mean AR across seasons (p = 0.016 and p = 0.029), identifying temporal and spatial relationships between water quality variables and AR. Importantly, when human, water, and wildlife isolates were examined, similar AR profiles were identified (p < 0.001). Our results suggest that direct human inputs are sufficient for extensive dispersal of AR into the environment, with landscape features, season, and water quality variables influencing AR dynamics. Focused and expensive efforts to minimize pollution from agricultural sources, while important, may only provide incremental benefits to the management of AR across complex landscapes. Controlling direct human AR inputs into the environment remains a critical and pressing challenge

P., De Corte, I., Misra, S., Bijma, J., de Beer, D., Reymond, C. E., Westphal, H., Ries, J. B., & Eagle, R. A. Thermal stress reduces pocilloporid coral resilience to ocean acidification by impairing control over calcifying fluid chemistry. Science Advances, 7(2), (2021): eaba9958, https://doi.org/10.1126/sciadv.aba9958.The combination of thermal stress and ocean acidification (OA) can more negatively affect coral calcification than an individual stressors, but the mechanism behind this interaction is unknown. We used two independent methods (microelectrode and boron geochemistry) to measure calcifying fluid pH (pHcf) and carbonate chemistry of the corals Pocillopora damicornis and Stylophora pistillata grown under various temperature and pCO2 conditions. Although these approaches demonstrate that they record pHcf over different time scales, they reveal that both species can cope with OA under optimal temperatures (28°C) by elevating pHcf and aragonite saturation state (Ωcf) in support of calcification. At 31°C, neither species elevated these parameters as they did at 28°C and, likewise, could not maintain substantially positive calcification rates under any pH treatment. These results reveal a previously uncharacterized influence of temperature on coral pHcf regulation—the apparent mechanism behind the negative interaction between thermal stress and OA on coral calcification.R.A.E. and J.B.R. acknowledge support from National Science Foundation grants OCE-1437166 and OCE-1437371.

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

The effects of an aerobic training intervention on cognition, grey matter volumes and white matter microstructure

While there is strong evidence from observational studies that physical activity is associated with reduced risk of cognitive decline and dementia, the extent to which aerobic training interventions impact on cognitive health and brain structure remains subject to debate. In a pilot study of 46 healthy older adults (66.6 years ± 5.2 years, 63% female), we compared the effects of a twelve-week aerobic training programme to a waitlist control condition on cardiorespiratory fitness, cognition and magnetic resonance imaging (MRI) outcomes. Cardiorespiratory fitness was assessed by VO2 max testing. Cognitive assessments spanned executive function, memory and processing speed. Structural MRI analysis included examination of hippocampal volume, and voxel-wise assessment of grey matter volumes using voxel-based morphometry. Diffusion tensor imaging analysis of fractional anisotropy, axial diffusivity and radial diffusivity was performed using tract-based spatial statistics. While the intervention successfully increased cardiorespiratory fitness, there was no evidence that the aerobic training programme led to changes in cognitive functioning or measures of brain structure in older adults. Interventions that are longer lasting, multi-factorial, or targeted at specific high-risk populations, may yield more encouraging results

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

Breast-cancer adjuvant therapy with zoledronic acid

Background: Data suggest that the adjuvant use of bisphosphonates reduces rates of recurrence and death in patients with early-stage breast cancer. We conducted a study to determine whether treatment with zoledronic acid, in addition to standard adjuvant therapy, would improve disease outcomes in such patients. Methods: In this open-label phase 3 study, we randomly assigned 3360 patients to receive standard adjuvant systemic therapy either with or without zoledronic acid. The zoledronic acid was administered every 3 to 4 weeks for 6 doses and then every 3 to 6 months to complete 5 years of treatment. The primary end point of the study was disease-free survival. A second interim analysis revealed that a prespecified boundary for lack of benefit had been crossed. Results: At a median follow-up of 59 months, there was no significant between-group difference in the primary end point, with a rate of disease-free survival of 77% in each group (adjusted hazard ratio in the zoledronic acid group, 0.98; 95% confidence interval [CI], 0.85 to 1.13; P=0.79). Disease recurrence or death occurred in 377 patients in the zoledronic acid group and 375 of those in the control group. The numbers of deaths — 243 in the zoledronic acid group and 276 in the control group — were also similar, resulting in rates of overall survival of 85.4% in the zoledronic acid group and 83.1% in the control group (adjusted hazard ratio, 0.85; 95% CI, 0.72 to 1.01; P=0.07). In the zoledronic acid group, there were 17 confirmed cases of osteonecrosis of the jaw (cumulative incidence, 1.1%; 95% CI, 0.6 to 1.7; P<0.001) and 9 suspected cases; there were no cases in the control group. Rates of other adverse effects were similar in the two study groups. Conclusions: These findings do not support the routine use of zoledronic acid in the adjuvant management of breast cancer.
