• To collect a database of all patients with ADHD in the adult mental health community team.
• Investigate current compliance with following NICE guidelines on physical health monitoring for patients with ADHD taking medication.
• Ensure all patients on medications were under the care of the Physical Health Monitoring Team (PHMT) who undertake the monitoring.
• Make recommendations for improvement in care where guidelines are not being adhered to.
Methods:
A database was compiled with patients suffering from ADHD and those on medications were noted.
The following criteria from the NICE guidelines on ADHD management were included:
• Baseline observations (heart rate (HR), blood pressure (BP), height, weight) – we reviewed this for those patients who had commenced ADHD medications less than one year ago.
• 6 monthly weight
• 6 monthly HR and BP
• 6 monthly psychiatry review
• Assessment for side effects at review – This includes cardiovascular issues, emerging tics / abnormal movements, sexual dysfunction, seizures, sleep, worsening behaviour
Results:
• 21/31 patients with confirmed ADHD were being medicated for same.
• 10/21 medicated patients were not under the care of the PHMT nor did they have a key worker.
• Medications included forms of methylphenidate or lisdexamfetamine and/or both:9/21 (43%) Concerta XL, 5/21 (24%) Equasym XL, Lisdexamfetamine 6/21 (29%), methylphenidate 3/21 (14%).
• 9/21 (43%) did not receive appropriate baseline observations.
• 14/21 (67%) did not have a 6 monthly weight documented.
• 15/21 (71%) did not have 6 monthly HR/BP checks
• 8/21 (38%) did not have a 6-month psychiatry review.
• Regarding assessment for side-effects, on reviewing clinical letters, 1/21 (5%) of letters did not document any discussion regarding side effects. Variation in side effects discussed was evident with 10/21 (48%) documenting general side effects such as sleep and 8/21 (38%) documenting more specific side effects such as tics or sexual dysfunction.
Conclusion:
This audit highlighted that ADHD monitoring was being neglected in a large percentage of patients on our ADHD database and variation in documentation regarding side effects.
• Review led to the following improvements being made:
• We developed an identifiable case load of patients with ADHD which is helpful for future audit and monitoring.
• Patients were referred to the PHMT for follow up of monitoring, helping to improve the likelihood that NICE guidelines will be adhered to.
• A reflection on the need for more specific documentation regarding monitoring of side effects in clinical letters.
This article reports a nine-month longitudinal study of fifteen children who, at the beginning of the study, ranged in age from 3;10 to 4;11. In the course of the study we traced the development of principles of control in their grammars and tested hypotheses about the linguistic analyses underlying the observed nonadult interpretations of constructions such as Grover tries pro to jump over the fence, Big Bird tells Ernie pro to jump over the fence, and Ernie kisses Cookie Monster before pro jumping over the fence. The study also investigated the children's judgments of pronominal reference in sentences such as Ernie kisses Cookie Monster before he jumps over the fence. The results confirm a developmental sequence that is driven by lexical learning and changing structural analyses. They also provide further information about a period experienced by some children in which pronominal reference is constrained in a manner that is clearly related to control phenomena.
Since the introduction of the academies policy and the growth of Multi-Academy Trusts (MATs) in England, there has been a shift away from public to private agendas as part of an increasing neoliberal, market-driven education system. Various studies have looked at this in terms of the large-scale implications for the culture of school governance (e.g. Wilkins, 2015), local democratic accountability (e.g. Gunter, 2011) and the impact of a centrally controlled system (e.g. Ball, 2017), but there has been limited exploration about what this means for governors and local governing boards at the local level. This chapter makes an empirical contribution to the existing literature by showing how national policy is being translated within one MAT at different levels of management and governance. It shows how fears about the blurring of boundaries between public/private bodies and practices are transpiring in two main ways. The first main finding from the ethnographic study of one MAT shows how the increased professionalisation of governance appears to be leading to a preference for a trust board which is weighted towards business skills, at the expense of educational expertise. Second, but related to the first, is the marginalisation of local figures, with their insider knowledge, and the implications for localised democratic oversight. The chapter concludes by arguing that there is an urgent need for university teacher educators/researchers with ‘insider’ expertise to work with schools to challenge the growing narrative of business-led education.
Ultra-high dose rate (UHDR) radiation, popularly known as FLASH, has been demonstrated to selectively kill tumor cells with minimal or negligible effects on normal cells but the biological effects induced by UHDR are not fully understood.
Methods
In this study, cytogenetic damage induced by UHDR radiation was compared with conventional dose rate (CDR) in human peripheral blood lymphocytes. Human blood samples were irradiated with 3 Gy and 8 Gy doses using 9 MeV electrons at 2 different dose rates: CDR 1 Gy/min and UHDR 600 Gy/Sec. Unstable and stable chromosomal aberrations were detected by fluorescence in situ hybridization (FISH).
Results
Reduced yields of chromosomal aberrations were observed after UHDR radiation at both radiation doses and the extent of reduction was more in colcemid arrested metaphase chromosomes than in G2-PCCs.
Conclusions
The reduced yields of chromosomal aberrations detected after UHDR of electrons may be due to rapid delivery of radiation dose within seconds, resulting in a non-uniform exposure of lymphocytes with varying levels of DNA damage induction. Future studies using well defined human equivalent in vivo and in vitro model systems are required to determine the underlying mechanisms for the FLASH effects.
Newborn bloodspot screening (NBS) is used to identify rare, serious health conditions. The choice of conditions to screen for can be contentious, with no internationally agreed panel. Multicriteria decision analysis (MCDA), involving a priori identification and weighting of criteria, has been proposed as an approach to assess and rank conditions for inclusion in newborn screening panels or for further assessment.
Methods
The aim of this review was to summarize existing MCDA-like processes used internationally in the context of NBS conditions. Publications were identified using a scoping methodology including electronic database and gray literature searches. Information on the methodology used to derive criteria and weightings, the criteria used, the scoring systems, and the weightings were extracted. The results were synthesized narratively.
Results
Five publications reporting on the use of MCDA or MCDA-like processes in the context of NBS were identified. In three publications, the aim of the MCDA processes was to select conditions for inclusion in an NBS panel. Two referred to the potential use of MCDA to inform prioritization of candidate conditions for future evaluation. While the criteria used were broadly consistent across studies, assigned weightings varied. Key challenges noted in the studies in relation to applying MCDA included the subjectivity associated with the choice and weighting of criteria, the absence of data to inform criteria, and its low discriminatory power.
Conclusions
Choosing criteria and weightings for MCDA processes regarding NBS can be a highly deliberative process that is intrinsically linked to the values and perspectives of those involved. Given the lack of international consensus on criteria and weightings, MCDA processes to aid decision-making would likely require a de novo tool or careful adaptation of an existing tool to reflect local contexts.
Herpes zoster and post-herpetic neuralgia (PHN) can cause significant pain and morbidity, impacting on the health-related quality of life of those affected. This research aimed to identify primary studies that elicited health state utility values (HSUVs) relating to both acute herpes zoster and PHN, and to assess their suitability for an economic model of herpes zoster vaccination.
Methods
Cost-effectiveness analyses of herpes zoster vaccination were identified from (i) a recently published systematic review of economic evaluations of herpes zoster vaccination and (ii) an independently conducted rapid review that sought to update the results of the identified systematic review. The evaluations were hand-searched to identify original studies that elicited HSUVs of interest. Narrative synthesis of the original study characteristics was conducted and possible sources of variation in the studies identified. Appraisal of the methodological quality of the studies was undertaken using a published open response tool that outlined key quality assessment criteria for HSUV studies.
Results
Twenty-one studies that elicited HSUVs were identified. Values related either to changes in utility resulting from increased pain severity, or to changes with time since disease onset. Heterogeneity was observed, potentially caused by differences in population size and characteristics, methods of elicitation, and preference weights used to value utility. Methodological quality varied across studies, with concerns around low sample sizes for populations with PHN, and poor reporting of both missing data and uncertainty around the HSUVs obtained. Differences in study population, time of participant recruitment, and methods of measuring utility could limit the applicability of HSUV study data.
Conclusions
This study highlights both the heterogeneity in HSUVs obtained for herpes zoster and the challenges associated with selecting HSUV data suitable for an economic model. An evidence base from which to select values for an economic evaluation has been created, though poor methodological quality and reporting of the primary studies may compromise the validity of point estimates obtained.
Sound general and sports nutrition knowledge in athletes is essential for making appropriate dietary choices. Assessment of nutrition knowledge enables evaluation and tailoring of nutrition education. However, few well-validated tools are available to assess nutrition knowledge in athletes. The objective of the present study was to establish the validity of the Platform to Evaluate Athlete Knowledge Sports – Nutrition Questionnaire (PEAKS-NQ) for use in the United Kingdom and Irish (UK-I) athletes. To confirm content validity, twenty-three sports nutritionists (SNs) from elite, UK-I sports institutes provided feedback on the PEAKS-NQ via a modified Delphi method. After minor changes, the UK-I version of the PEAKS-NQ was administered to UK-I SN from the British Dietetic Association Sport and Exercise Nutrition Register, and elite athletes (EA) training at elite sports institutes in the UK and Ireland. Independent samples t-test and independent samples median tests were used to compare PEAKS-NQ total and subsection scores between EA and SN (to assess construct validity). Cronbach's alpha (good ≥ 0⋅7) was used to establish internal consistency. The SN achieved greater overall [SN (n 23) 92⋅3 (9⋅3) v. EA (n 154): 71⋅4 (10⋅0)%; P < 0⋅001] and individual section scores (P < 0⋅001) except Section B, Identification of Food Groups (P = 0⋅07). Largest knowledge differences between SN and EA were in Section D, Applied Sports Nutrition [SN: 88⋅5 (8⋅9) v. EA: 56⋅7 (14⋅5)%; P < 0⋅00]. Overall ES was large (2⋅1), with subsections ranging from 0⋅6 to 2⋅3. Cronbach's alpha was good (0⋅83). The PEAKS-NQ had good content and construct validity, supporting its use to assess nutrition knowledge of UK-I athletes.
Growing evidence suggests that air pollution exposure may adversely affect the brain and increase risk for psychiatric disorders such as schizophrenia and depression. However, little is known about the potential role of air pollution in severity and relapse following illness onset.
Aims
To examine the longitudinal association between residential air pollution exposure and mental health service use (an indicator of illness severity and relapse) among individuals with first presentations of psychotic and mood disorders.
Method
We identified individuals aged ≥15 years who had first contact with the South London and Maudsley NHS Foundation Trust for psychotic and mood disorders in 2008–2012 (n = 13 887). High-resolution (20 × 20 m) estimates of nitrogen dioxide (NO2), nitrogen oxides (NOx) and particulate matter (PM2.5 and PM10) levels in ambient air were linked to residential addresses. In-patient days and community mental health service (CMHS) events were recorded over 1-year and 7-year follow-up periods.
Results
Following covariate adjustment, interquartile range increases in NO2, NOx and PM2.5 were associated with 18% (95% CI 5–34%), 18% (95% CI 5–34%) and 11% (95% CI 3–19%) increased risk for in-patient days after 1 year. Similarly, interquartile range increases in NO2, NOx, PM2.5 and PM10 were associated with 32% (95% CI 25–38%), 31% (95% CI 24–37%), 7% (95% CI 4–11%) and 9% (95% CI 5–14%) increased risk for CMHS events after 1 year. Associations persisted after 7 years.
Conclusions
Residential air pollution exposure is associated with increased mental health service use among people recently diagnosed with psychotic and mood disorders. Assuming causality, interventions to reduce air pollution exposure could improve mental health prognoses and reduce healthcare costs.
The Subglacial Antarctic Lakes Scientific Access (SALSA) Project accessed Mercer Subglacial Lake using environmentally clean hot-water drilling to examine interactions among ice, water, sediment, rock, microbes and carbon reservoirs within the lake water column and underlying sediments. A ~0.4 m diameter borehole was melted through 1087 m of ice and maintained over ~10 days, allowing observation of ice properties and collection of water and sediment with various tools. Over this period, SALSA collected: 60 L of lake water and 10 L of deep borehole water; microbes >0.2 μm in diameter from in situ filtration of ~100 L of lake water; 10 multicores 0.32–0.49 m long; 1.0 and 1.76 m long gravity cores; three conductivity–temperature–depth profiles of borehole and lake water; five discrete depth current meter measurements in the lake and images of ice, the lake water–ice interface and lake sediments. Temperature and conductivity data showed the hydrodynamic character of water mixing between the borehole and lake after entry. Models simulating melting of the ~6 m thick basal accreted ice layer imply that debris fall-out through the ~15 m water column to the lake sediments from borehole melting had little effect on the stratigraphy of surficial sediment cores.
Reliable and valid assessment of sports nutrition knowledge can inform athlete nutrition education to address knowledge gaps. This study aimed to test the reliability and validity of an electronically administered sports nutrition knowledge tool – Platform to Evaluate Athlete Knowledge of Sports Nutrition Questionnaire (PEAKS-NQ). A 94-item PEAKS-NQ was piloted to 149 developmental athletes (DA) in New Zealand, with a subset invited to complete the PEAKS-NQ again to assess reliability. Reliability was evaluated using sign test, intraclass correlation and Cronbach’s α. Accredited sports dietitians (ASD; n 255) completed the PEAKS-NQ to establish construct validity via known-groups methodology and provided relevance scores to determine the scale content validity index (S-CVI). Rasch analysis was conducted to identify potentially problematic items and test reliability. Score differences between DA and ASD were analysed using independent t or non-parametric tests. DA (n 88) were 17·8 (sd 1·4) years, 61·4 % female and mostly in high school (94·3 %). ASD (n 45) were 37·8 (sd 7·6) years, 82·2 % female, with >5 years of dietetic experience (59·1 %). ASD scored higher than DA in all sections and overall (91·5 (sd 3·4) v. 67·1 (sd 10·5) %) (P < 0·001). There were no differences between retests (n 18; P = 0·14). Cronbach’s α was 0·86. S-CVI indicated good content validity (0·88). Rasch analysis resulted in a fifty-item PEAKS-NQ with high item (0·91) and person (0·92) reliability. The PEAKS-NQ is reliable and valid for assessing sports nutrition knowledge which could assist practitioners effectively tailor and evaluate nutrition education.
Nutrition education programmes for athletes aim to enhance nutrition knowledge and more importantly support positive dietary change to enhance performance, health and well-being. This systematic review assessed changes in the dietary intakes of athletes in response to nutrition education programmes. A search was conducted which included studies providing quantitative dietary intake assessment of athletes of any calibre aged between 12 and 65 years in response to a nutrition education programme. Standardised differences (effect sizes) were calculated (when possible) for each dietary parameter. The search yielded 6285 papers with twenty-two studies (974 participants (71·9 % female)) eligible for inclusion. Studies described athletes competing at high school (n 3) through to college level or higher (n 19). Study designs were either single arm with an intervention-only group (twelve studies; n 241) or double arm including an intervention and control group (ten studies; n 689). No control groups received an alternative or ‘sham’ intervention. Face-to-face lectures (9/22) and individual nutrition counselling (6/22) were the most common education interventions. Non-weighed, 3-d diet records (10/22) were the most frequently utilised dietary assessment method. Although 14/22 studies (n 5 single and n 9 double) reported significant change in at least one nutrition parameter, dietary changes were inconsistent. Poor study quality and heterogeneity of methods prohibit firm conclusions regarding overall intervention success or superior types of educational modalities. Of note, carbohydrate intakes ‘post-intervention’ when assessed often failed to meet recommended guidelines (12/17 studies). Given the substantial investment made in nutrition education interventions with athletes, there is a need for well-designed and rigorous research to inform future best practice.
This study explored the concept of ‘giving up’ from the perspective of care staff working in care homes, and their everyday communication and hidden knowledge concerning what they think about this taboo topic and the context it reflects. Moving to a care home is a major transition where cumulative losses can pose risks to mental health in later life. If not recognised, this vulnerability can lead to depression which extends to suicide ideation and behaviours in the form of self-harm and self-neglect. Care homes are a significant place of care until death, yet a discourse of silence means that self-harm and suicide is under-reported or not attended to with specialist expertise. The layperson's concept of an older person ‘giving up’ on life is hardly discussed in the literature. This co-produced qualitative study used an inductive approach to explore this phenomenon through focus groups with 33 care staff across four care homes in South-East England. Findings paint a complex picture, highlighting tensions in providing the right support and creating spaces to respond to such challenging situations. ‘Giving up’ requires skilled detailed assessment to respond to risks alongside improved training and support for paid carers, to achieve a more holistic strategy which capitalises on significant relationships within a wider context.
Ten ice-sheet models are used to study sensitivity of the Greenland and Antarctic ice sheets to prescribed changes of surface mass balance, sub-ice-shelf melting and basal sliding. Results exhibit a large range in projected contributions to sea-level change. In most cases, the ice volume above flotation lost is linearly dependent on the strength of the forcing. Combinations of forcings can be closely approximated by linearly summing the contributions from single forcing experiments, suggesting that nonlinear feedbacks are modest. Our models indicate that Greenland is more sensitive than Antarctica to likely atmospheric changes in temperature and precipitation, while Antarctica is more sensitive to increased ice-shelf basal melting. An experiment approximating the Intergovernmental Panel on Climate Change’s RCP8.5 scenario produces additional first-century contributions to sea level of 22.3 and 8.1 cm from Greenland and Antarctica, respectively, with a range among models of 62 and 14 cm, respectively. By 200 years, projections increase to 53.2 and 26.7 cm, respectively, with ranges of 79 and 43 cm. Linear interpolation of the sensitivity results closely approximates these projections, revealing the relative contributions of the individual forcings on the combined volume change and suggesting that total ice-sheet response to complicated forcings over 200 years can be linearized.
To compare the nutrient profile of packaged supermarket food products available in Australia and New Zealand. Eligibility to carry health claims and relationship between nutrient profile score and nutritional content were also evaluated.
Design
Nutritional composition data were collected in six major Australian and New Zealand supermarkets in 2012. Mean Food Standards Australia New Zealand Nutrient Profiling Scoring Criterion (NPSC) scores were calculated and the proportion of products eligible to display health claims was estimated. Regression analyses quantified associations between NPSC scores and energy density, saturated fat, sugar and sodium contents.
Results
NPSC scores were derived for 23 596 packaged food products (mean score 7·0, range −17 to 53). Scores were lower (better nutrient profile) for foods in Australia compared with New Zealand (mean 6·6 v. 7·8). Overall, 45 % of foods were eligible to carry health claims based on NPSC thresholds: 47 % in Australia and 41 % in New Zealand. However, less than one-third of dairy (32 %), meat and meat products (28 %) and bread and bakery products (27·5 %) were eligible to carry health claims. Conversely, >75 % of convenience food products were eligible to carry health claims (82·5 %). Each two-unit higher NPSC score was associated with higher energy density (78 kJ/100 g), saturated fat (0·95 g/100 g), total sugar (1·5 g/100 g) and sodium (66 mg/100 g; all P values<0·001).
Conclusions
Fewer than half of all packaged foods available in Australia and New Zealand in 2012 met nutritional criteria to carry health claims. The few healthy choices available in key staple food categories is a concern. Improvements in nutritional quality of foods through product reformulation have significant potential to improve population diets.
Increasing atmospheric carbon dioxide, changing climates, nitrogen deposition and other aspects of anthropogenic global change are hypothesised to be changing forest productivity and biomass stocks in tropical forests and elsewhere (Clark 2004; Lewis, Malhi & Phillips 2004; Lewis et al. 2009a; Luo, 2007; Myeni et al. 1997). These hypotheses continue to be much debated, with contrary views on the plausibility of particular mechanisms and on the status of current evidence for or against them (Clark 2007; Friedlingstein et al. 2006; Holtum & Winter 2010; Körner 2009; Wright 2005, 2010). The influence of atmospheric and climate change on forest biomass is of particular interest because of the potential for positive or negative feedbacks. Increases in forest biomass and associated carbon pools would slow the rise in atmospheric carbon dioxide, producing a negative feedback, whereas decreases in forest biomass would have the opposite effect. Uncertainty surrounding these feedbacks is considerable at the global scale, with important implications for global carbon budgets (Luo 2007).
In view of this, it is essential to know whether forests are experiencing changes in productivity and biomass in excess of those typical for their age. Successional forests, those regrowing after disturbances, increase in biomass over time, with the trajectory and duration of this increase varying with forest type (Bormann & Likens 1979; Odum 1969). In the absence of global change, such forests are expected to eventually reach a dynamic equilibrium in which biomass gains from growth and recruitment are balanced by biomass losses from tree death and branchfall, and these old-growth forests thus experience no directional changes in biomass (Odum 1969; Yang, Luo & Finzi 2011). Accordingly, detection of directional changes in biomass in old-growth forests is generally considered evidence of global change influences. When and where such changes are detected, the next critical question concerns prediction of future net carbon fluxes and ultimate carbon stocks of such altered forests.
Risk factors for pre-eclampsia represent a bewildering array of causative antecedents that reflect the complexity of the maternal syndrome. The HELLP syndrome is most commonly regarded as related to severe pre-eclampsia. Assessment of cerebral function via continuous communication with the awake patient is essential and provides important hemodynamic information. Transcranial Doppler measurements have given interesting insight in cerebral hemodynamics in pre-eclampsia. The choice of anti-hypertensive agent should be guided by local experience and continuous monitoring of blood pressure and flow, both for the mother and the baby. Intravascular volume depletion has been considered the norm in women with pre-eclampsia. Prevention of pre-eclampsia-related cerebral complications is one of the major indications for observation and treatment in ICU. Prevention and management of eclamptic seizures is based upon giving magnesium sulfate. Patients with HELLP syndrome have an increased risk of venous thromboembolism and bleeding during pregnancy.
The role of metabolomics in the field of nutrition is continuing to grow and it has the potential to assist in the understanding of metabolic regulation and explain how minor perturbations can have a multitude of biochemical endpoints. It is this development, which creates the potential to provide the knowledge necessary to facilitate a more targeted approach to nutrition. In recent years, there has been interest in applying metabolomics to examine alterations in the metabolic profile according to weight gain/obesity. Emerging from these studies is the strong evidence that alterations in the amino acid (AA) profiles are associated with obesity. Several other studies have also shown a relationship between branched-chain amino acids (BCAA), obesity and insulin resistance. The present review focuses on the proposed link between AA and in particular BCAA, obesity and insulin resistance. In conclusion, a wealth of information is accumulating to support the role of AA, and in particular of the BCAA, in obesity.
