Project description:ObjectivesThere has been very little description of the health and social outcomes at pregnancy and early motherhood of girls who were previously looked after by local authorities. The objectives of this study were to compare the sociodemographic and health profiles of mothers who had spent time in a children's home or with foster parents as a child to mothers who had not. In particular, to examine associations between being looked after and the likelihood of smoking during pregnancy, birth weight, the presence of symptoms of maternal depression and the initiation of breastfeeding.DesignA retrospective cross-sectional study using the baseline questionnaire of the Millennium Cohort Study.SettingThe UK.ParticipantsA nationally representative study of 18,492 mothers of babies born in the UK during 2000-2002.ExposureA history of spending time in a children's home or with foster parents.Outcome measures(1) Smoking during pregnancy; (2) low birth weight; (3) symptoms of maternal depression and (4) initiation of breastfeeding.ResultsIn univariable analyses, women who had been looked after by local authorities were significantly less likely to be of a higher social class, live in a high-income household or have achieved a high level of education. They were more likely to have a low-birthweight baby and be a single parent. In multivariable analyses, women who had been looked after by local authorities were more likely to smoke during pregnancy (adjusted OR 3.0 95% CI 2.14 to 4.3) and were more likely to have symptoms of depression (adjusted OR 1.98 95% CI 1.4 to 2.7) compared with women who had not been looked after.ConclusionsOur results suggest that these women carry social disadvantage into motherhood, with the potential of continuing the cycle of deprivation. There is a case for increasing our attention on this group, which can be readily accessed by maternity and early years' services.

Project description:Low-grade, chronic inflammation during ageing (“inflammageing”) is suggested to be involved in the development of frailty in older age. However, studies on the association between frailty, using the frailty index definition, and inflammatory markers are limited. The aim of this study was to investigate the relationship between inflammatory markers and frailty index (FI) in older, home-dwelling adults. Home-dwelling men and women aged ≥ 70 years old, living in South-East Norway were recruited and included in a cross-sectional study. The FI used in the current study was developed according to Rockwood’s frailty index and included 38 variables, resulting in an FI score between 0 and 1 for each participant. Circulating inflammatory markers (IL-6, CRP, IGF-1, cystatin C, cathepsin S, and glycoprotein Acetyls) were analyzed from non-fasting blood samples using ELISA. Whole-genome PBMC transcriptomics was used to study the association between FI score and inflammation. The present study was a cross-sectional study that included home-dwelling men and women aged ≥ 70 years old, living in the Skedsmo area, South-East Norway. The study was conducted in 2014/2015 and has been described previously [Ottestad I, Ulven SM, Øyri LKL, Sandvei KS, Gjevestad GO, Bye A, et al. Reduced plasma concentration of branched-chain amino acids in sarcopenic older subjects: a cross-sectional study. Br J Nutr. 2018;120(4):445-53]. The participants were recruited by the National Register and received an invitation letter by mail. Briefly, a total of 2820 subjects were invited, and 437 subjects participated in the study. The participants met for a single study visit, and data was collected on dietary intake, body weight and composition, physical performance, medical history, cognitive function, risk of malnutrition, anthropometric measurements, blood pressure, heart rate, and quality of life. Non-fasting blood samples were also collected.

Project description:BackgroundChildhood immunisation is a critically important public health initiative. However, since most vaccines are administered by injection, it is associated with considerable pain and distress. Despite evidence demonstrating the efficacy of various pain management strategies, the frequency with which these are used during routine infant vaccinations in UK practice is unknown.AimThis study aimed to explore primary care practice nurses' (PNs) use of evidence-based pain management strategies during infant immunisation, as well as barriers to evidence-based practice.MethodsA questionnaire was developed and distributed to nurses throughout the UK via convenience sampling in paper and online formats. Questions assessed the frequency of pain management intervention use during infant immunisation and barriers to their use.FindingsA total of 255 questionnaire responses were received. Over 90% (n = 226) of respondents never used topical anaesthetics or sweet solutions during immunisations, while 41.9% advised breastfeeding occasionally (n = 103). Parent-/caregiver-led distraction was the most frequently used intervention, with most nurses using it occasionally (47.9%, n = 116) or often (30.6%, n = 74). Most practices had no immunisation pain management policy (81.1%, n = 184), and most PNs' previous training had not included pain management (86.9%, n = 186). Barriers to intervention use included lack of time, knowledge and resources. Excluding distraction, pain management strategies were infrequently or never used during infant immunisation. Key barriers to using evidence-based strategies were lack of time, knowledge and resources.

Project description:Carriage of Neisseria meningitidis, the meningococcus, is a prerequisite for invasive meningococcal disease (IMD), a potentially devastating infection that disproportionately afflicts infants and children. Humans are the sole known reservoir for the meningococcus, and it is carried asymptomatically in the nasopharynx of ~10% of the population. Rates of carriage are dependent on age of the host and social and behavioural factors. In the UK, meningococcal carriage has been studied through large, multi-centre carriage surveys of adolescents in 1999, 2000, and 2001, demonstrating carriage can be affected by immunisation with the capsular group C meningococcal conjugate vaccine, inducing population immunity against carriage. Fifteen years after these surveys were carried out, invasive meningococcal disease incidence had declined from a peak in 1999. The UKMenCar4 study was conducted in 2014/15 to investigate rates of carriage amongst the adolescent population during a period of low disease incidence. The protocols and methodology used to perform UKMenCar4, a large carriage survey, are described here.

Project description:BackgroundThe incidence of invasive meningococcal disease in the UK decreased by approximately four times from 1999 to 2014, with reductions in serogroup C and serogroup B disease. Lower serogroup C invasive meningococcal disease incidence was attributable to implementation of the meningococcal serogroup C conjugate vaccine in 1999, through direct and indirect protection, but no vaccine was implemented against serogroup B disease. UK Meningococcal Carriage surveys 1-3 (UKMenCar1-3), conducted in 1999, 2000, and 2001, were essential for understanding the impact of vaccination. To investigate the decline in invasive meningococcal disease incidence, we did a large oropharyngeal carriage survey in 2014-15, immediately before the changes to meningococcal vaccines in the UK national immunisation schedule.MethodsUKMenCar4 was a cross-sectional survey in adolescents aged 15-19 years who were enrolled from schools and colleges geographically local to one of 11 UK sampling centres between Sept 1, 2014, and March 30, 2015. Participants provided an oropharyngeal swab sample and completed a questionnaire on risk factors for carriage, including social behaviours. Samples were cultured for putative Neisseria spp, which were characterised with serogrouping and whole-genome sequencing. Data from this study were compared with the results from the UKMenCar1-3 surveys (1999-2001).FindingsFrom the 19 641 participants (11 332 female, 8242 male, 67 not stated) in UKMenCar4 with culturable swabs and completed risk-factor questionnaires, 1420 meningococci were isolated, with a carriage prevalence of 7·23% (95% CI 6·88-7·60). Carriage prevalence was substantially lower in UKMenCar4 than in the previous surveys: carriage prevalence was 16·6% (95% CI 15·89-17·22; 2306/13 901) in UKMenCar1 (1999), 17·6% (17·05-18·22; 2873/16 295) in UKMenCar2 (2000), and 18·7% (18·12-19·27; 3283/17 569) in UKMenCar3 (2001). Carriage prevalence was lower for all serogroups in UKMenCar4 than in UKMenCar1-3, except for serogroup Y, which was unchanged. The prevalence of carriage-promoting social behaviours decreased from 1999 to 2014-15, with individuals reporting regular cigarette smoking decreasing from 2932 (21·5%) of 13 650 to 2202 (11·2%) of 19 641, kissing in the past week from 6127 (44·8%) of 13 679 to 7320 (37·3%) of 19 641, and attendance at pubs and nightclubs in the past week from 8436 (62·1%) of 13 594 to 7662 (39·0%) of 19 641 (all p<0·0001).InterpretationWe show that meningococcal carriage prevalence in adolescents sampled nationally during a low incidence period (2014-15) was less than half of that in an equivalent population during a high incidence period (1999-2001). Disease and carriage caused by serogroup C was well controlled by ongoing vaccination. The prevalence of behaviours associated with carriage declined, suggesting that public health policies aimed at influencing behaviour might have further reduced disease.FundingWellcome Trust, UK Department of Health, and National Institute for Health Research.

Project description:BackgroundLocal authorities (LAs) are increasingly aiming to become more research active. Research ethics review is an important prerequisite of high-quality research. It is not clear what a LA ethics review process can (or should) look like, or whether it is needed in addition to external review processes. We aim to describe the scope and purpose of research ethics processes in LAs across England, and factors that are salient to their design.Study designQualitative interview study.MethodsStaff from 15 LAs in England were recruited to describe their research ethics process using purposeful and snowball sampling. One-hour interviews were conducted using a topic guide with five scenarios, drawn from LA projects. Interview transcripts were thematically analysed using a consensus building process among the research team.ResultsFactors salient to the design of research ethics processes in LAs included: definitions of research, research ownership, and the distinct relationship LAs have with research participants. A typology with four models is used to describe existing processes. These models are: No Process; The Assurance Model (where LAs assure an external ethics committee has reviewed projects); The Advice Model (where there is no formal review, but ethical considerations are made through formal and informal advice); and The Review Model (where LAs establish their own formal internal ethics committees). These typologies emerged from divergent understandings of the role of research in LAs and can reflect varied views of research as an activity "done to a local authority", "done with a local authority" or "owned by a local authority".DiscussionResearch ethics processes in LAs need to reflect various LA approaches to what constitutes research, who owns the research process, and how a LAs relationship with research participants may vary from other settings. As LAs continue articulating what research means in their setting, they need support and guidance to establish research ethics processes that enable research activity, while simultaneously being sensitive to the level of research readiness and distinct LA need.

Project description:Serogroup B is the only major disease-associated capsular group of Neisseria meningitidis for which no protein-polysaccharide conjugate vaccine is available. This has led to the development of multi-component protein-based vaccines that target serogroup B invasive meningococcal disease (IMD), including Bexsero®, which was implemented for UK infants in 2015, and Trumenba®. Given the diversity of meningococcal protein antigens, post-implementation surveillance of IMD isolates, including characterisation of vaccine antigens, is essential for assessing the effectiveness of such vaccines. Whole genome sequencing (WGS), as realised in the Meningitis Research Foundation Meningococcus Genome Library (MRF-MGL), provides a rapid, comprehensive, and cost-effective approach to this. To facilitate the surveillance of the antigen targets included in Bexsero® (fHbp, PorA, NHBA and NadA) for protective immunity, a Bexsero® Antigen Sequence Type (BAST) scheme, based on deduced peptide sequence variants, was implemented in the PubMLST.org/neisseria database, which includes the MRF-MGL and other isolate collections. This scheme enabled the characterisation of vaccine antigen variants and here the invasive meningococci isolated in Great Britain and Ireland in the epidemiological years 2010/11 to 2013/14 are analysed. Many unique BASTs (647) were present, but nine of these accounted for 39% (775/1966) of isolates, with some temporal and geographic differences in BAST distribution. BASTs were strongly associated with other characteristics, such as serogroup and clonal complex (cc), and a significant increase in BAST-2 was associated with increased prevalence of serogroup W clonal complex 11 meningococci. Potential coverage was assessed by the examination of the antigen peptide sequences present in the vaccine and epidemiological dataset. There were 22.8-30.8% exact peptide matches to Bexsero® components and predicted coverage of 66.1%, based on genotype-phenotype modelling for 63.7% of serogroup B isolates from 2010/14 in UK and Ireland. While there are many caveats to this estimate, it lies within the range of other published estimates.

Project description:The COVID-19 pandemic suggests that there are opportunities to improve preparedness for infectious disease outbreaks. While much attention has been given to understanding national-level preparedness, relatively little attention has been given to understanding preparedness at the local-level. We, therefore, aim to describe (1) how local governments in urban environments were engaged in epidemic preparedness efforts before the COVID-19 pandemic and (2) how they were coordinating with authorities at higher levels of governance before COVID-19. We developed a survey and distributed it to 50 cities around the world involved in the Partnership for Healthy Cities. The survey included several question formats including free-response, matrices, and multiple-choice questions. RACI matrices, a project management tool that helps explain coordination structures, were used to understand the level of government responsible, accountable, consulted, and informed regarding select preparedness activities. We used descriptive statistics to summarize local-level engagement in preparedness. Local authorities from 33 cities completed the survey. Prior to the COVID-19 pandemic, 20 of the cities had completed infectious disease risk assessments, 10 completed all-hazards risk assessments, 11 completed simulation exercises, 10 completed after-action reviews, 19 developed preparedness and response plans, three reported involvement in their country's Joint External Evaluation of the International Health Regulations, and eight cities reported involvement in the development of their countries' National Action Plan for Health Security. RACI matrices revealed various models of epidemic preparedness, with responsibility often shared across levels, and national governments accountable for the most activities, compared to other governance levels. In conclusion, national governments maintain the largest role in epidemic and pandemic preparedness but the role of subnational and local governments is not negligible. Local-level actors engage in a variety of preparedness activities and future efforts should strive to better include these actors in preparedness as a means of bolstering local, national, and global health security.
