Abstract
To identify the most effective strategies for implementing and sustaining Tier 2 and 3 behavior support systems, a measure of general and tier-specific factors hypothesized to predict sustained implementation is needed. To address this need, we conducted two studies examining the construct validity of the Advanced Level Tier Interventions Treatment Utilization and Durability Evaluation (ALTITUDE) measure: one assessing the content aspects of construct validity (Study 1) and one assessing the structural and external aspects of construct validity (Study 2). In Study 1, participants included an expert panel of 26 members who provided iterative feedback during measure development. The results showed strong content representativeness (content validity index = .93) for assessing elements indicating sustainability. In Study 2, participants were school personnel from 646 schools who completed the measure. The results showed model fit was good for both a three-factor correlated model (CFI = .98, RMSEA = .06, SRMR = .05) and Bifactor S-1 model with correlated Tier 2 and Tier 3 specific residual factors (CFI = .98, RMSEA = .06, SRMR = .05). In addition, ALTITUDE latent factors were found to have both convergent and discriminant evidence in relation to concurrent fidelity of school-wide positive behavioral interventions and supports (SWPBIS) implementation at Tiers 1, 2, and 3. This construct validity evidence will support the use of the ALTITUDE in identifying the strongest tier-general and tier-specific predictors of sustained implementation of Tier 2 and 3 behavior support systems.

Abstract
Background Despite the recognised advantages of bariatric and metabolic surgery, only a small proportion of patients receive this intervention. In the UK, weight management systems are divided into four tiers. Tier 3 is a clinician-lead weight loss service while tier 4 considers surgery. While there is little evidence that tier 3 has any long-term benefits for weight loss, this study aims to determine whether tier 3 improves the uptake of surgery. Method A retrospective cohort study of all referrals to our unit between 2013 and 2016 was categorised according to source—tier 3, directly from the general practitioner (GP) or from another speciality. The likelihood of surgery was calculated using a regression model after considering patient demographics, comorbidities and distance from our hospital. Results Of the 399 patients, 69.2% were referred directly from the GP, 21.3% from tier 3, and 9.5% from another speciality of which 69.4%, 56.2%, and 36.8% progressed to surgery (p = 0.01). On regression analysis, patients from another speciality or GP were more likely to decide against surgery (OR 2.44 CI 1.13–6.80 p = 0.03 and OR 1.65 CI 1.10–3.12 p = 0.04 respectively) and more likely to be deemed not suitable for surgery by the MDT (OR 6.42 CI 1.25–33.1 p = 0.02 and OR 3.47 CI 1.11–12.9 p = 0.03) compared with tier 3 referrals. Conclusion As patients from tier 3 were more likely to undergo bariatric and metabolic surgery, this intervention remains a relevant step in the pathway. Such patients are likely to be better informed about the benefits of surgery and risks of severe obesity.

Abstract
PURPOSE OF THE REVIEW Pathways for obesity prevention and treatment are well documented, yet the prevalence of obesity is rising, and access to treatment (including bariatric surgery) is limited. This review seeks to assess the current integrated clinical pathway for obesity management in England and determine the major challenges. RECENT FINDINGS Evidence for tier 2 (community-based lifestyle intervention) and tier 3 (specialist weight management services) is limited, and how it facilitates care and improve outcomes in tier 4 remains uncertain. Treatment access, rigidity in pathways, uncertain treatment outcomes and weight stigma seems to be major barriers to improved care. More emphasis must be placed on access to effective treatments, treatment flexibility, addressing stigma and ensuring treatment efficacy including long-term health outcomes. Prevention and treatment should both receive significant focus though should be considered to be largely separate pathways. A simplified system for weight management is needed to allow flexibility and the delivery of personalized care including post-bariatric surgery care for those who need it.

Abstract
In mitigating greenhouse gas (GHG) emissions and reducing the carbon footprint of dairy milk, the use of generic estimates in inventory and accounting methodology at farm level largely ignores variation of on-farm GHG emissions. The present study aimed to implement results of an extant dynamic, mechanistic Tier 3 model for enteric methane (CH4) (applied in Dutch national GHG inventory) in order to capture variation in enteric CH4 emission, and in faecal N and organic matter (OM) digestibility, ultimately required to predict manure CH4 and ammonia emission. Tier 3 model predictions were translated into calculation rules that could easily be implemented in an annual nutrient cycling assessment tool including GHG emissions, which is currently used by Dutch dairy farmers. Calculations focussed on (1) enteric CH4 emission, (2) apparent faecal OM digestibility and (3) apparent faecal N digestibility. Enteric CH4 was expressed in CH4 yield indicated with the term emission factor (EF; g CH4/kg DM) for individual dietary components and feedstuffs. Factors investigated to cover predicted variation in EF value included the level of feed intake, the type of roughage fed (proportions of grass silage and maize silage) and the quality of roughage fed. A minimum number of three classes of roughage type (i.e. 0. 40% and 80% maize silage in roughage DM) appeared necessary to obtain correspondence between interpolated EF values from EF lists and Tier 3 model predictions. A linear decline in EF value with 1% per kg increase in DM intake is adopted based on model simulations. The quality of roughage was represented by the effect of maturity of harvested grass or of the whole plant maize at cutting, based on a survey of modelling as well as experimental work. Also, predictions were assembled for apparent faecal OM digestibility which could be used in national inventory and in farm accounting. Apparent faecal N digestibility (as a major determinant of predicted urinary N excretion) was predicted, to support current Dutch national ammonia emission inventory and to correct the level of N digestibility in farm accounting. Compared to generic values or values retrieved from the Dutch feeding tables, predicted OM and N digestibility and enteric CH4 are better rooted in physiological principles and better reflect observed variation under experimental conditions. The present results apply for conditions with fairly intensive grassland management in temperate regions.

Abstract
PURPOSE OF REVIEW Rising demand for specialised "Tier 3" weight management services in England is exceeding capacity, leading many services to offer group-based care programmes. This review considers the organisation of current provision, exploring how group programmes may enhance services and how these could be scaled up for wider implementation. RECENT FINDINGS Existing group-based programmes mainly focus on providing patients with information and education about their condition. Evidence suggests that groups themselves offer therapeutic benefits beyond this, by underpinning patients' engagement with programme materials and contributing to wider health and well-being. To maximise these benefits, there is a need to attend to the group processes that emerge in treatment groups which, left unchecked, may limit or even adversely impact programme outcomes. Group-based interventions may be of benefit to patients in Tier 3 specialist weight management services, although their format is complex and reliant on facilitators' expertise.

Abstract
BACKGROUND NHS England has recommended a multidisciplinary weight management services (MWMS-Tier 3 services) for patients requiring specialized management of obesity, including bariatric surgery, but clinical and measurable health-related outcomes from these services remains fragmented. We therefore undertook a systematic review to explore the evidence base of effect on body weight loss and comorbidities outcomes of Tier 3 or UK pre-bariatric MWMPs. METHODS AMED, CINAHL, EMBASE, HMIC, MEDLINE, PsycINFO, PubMed, HDAS search and Google Scholar were searched from January 2000 to September 2017 in a free-text fashion and crossed-references of included studies to identify potential illegibility. Inclusion criteria were as follows: (a) published Tier 3 original study abstracts/articles; (b) intervention studies with before and after data; (c) studies that included any sort of MWMPs conducted on British residents with obesity; and (d) studies included T2DM measurements in a MWMPs. RESULTS In total, 19 studies met the inclusion criteria. The total number of participants analysed was N = 11,735. Baseline accumulative average BMI was calculated at 42.54 kg/m2, weight 117.88 kg and waist circumference 126.9 cm. And at 6 months, 40.73 kg/m2, 112.17 kg and 120.3 cm, respectively. Secondary outcome variables were as improved with reduction in HbA1c, fasting blood sugars, insulin usage and blood pressure. Physical activity increased at 3 months then declined after 6 months with no significant changes in cholesterol levels. CONCLUSION Tier 3 and MWMPs have a short to mid-ranged positive effect on obese patients (BMI ≥30 kg/m2) living in the UK regarding accumulated reduction in weight, glycaemic control, blood pressure and with subtle improvements in physical activity.

Abstract
Specialist weight management services provide a treatment option for severe obesity. The objective of the study is to review the characteristics, impact and practice implications of specialist weight management services for adults in the UK. Systematic review: EMBASE, MEDLINE and PsycINFO were searched from January 2005 to March 2016 with supplementary searches. Adults with a body mass index of ≥40 kg m-2 , or ≥35 kg m-2 with comorbidity or ≥30 kg m-2 with type 2 diabetes and any study of multicomponent interventions, in any UK or Ireland setting, delivered by a specialist multidisciplinary team are the inclusion criteria. Fourteen studies in a variety of settings were included: 1 randomized controlled trial, 3 controlled and 10 observational studies. Mean baseline body mass index and age ranged from 40 to 54 kg m-2 and from 40 to 58 years. The studies were heterogeneous making comparisons of service characteristics difficult. Multidisciplinary team composition and eligibility criteria varied; dropout rates were high (43-62%). Statistically significant reduction in mean body mass index over time ranged from -1.4 to -3.1 kg m-2 and mean weight changes ranged from -2.2 to -12.4 kg. Completers achieving at least 5% reduction of initial body weight ranged from 32 to 51%. There was evidence for improved outcomes in diabetics. Specialist weight management services can demonstrate clinically significant weight loss and have an important role in supporting adults to manage severe and often complex forms of obesity. This review highlights important variations in provision and strongly indicates the need for further research into effective approaches to support severely obese adults.

Abstract
In the UK, as in most other countries in the world, levels of obesity are increasing. According to the Kinsey report, obesity has the second largest public health impact after smoking, and it is inextricably linked to physical inactivity. Since the UK Health and Social Care Act reforms of 2012, there has been a significant restructuring of the National Health Service (NHS). As a consequence, NHS England and the Department of Health have issued new policy guidelines regarding the commissioning of obesity treatment. A 4-tier model of care is now widely accepted and ranges from primary activity, through community weight management and specialist weight management for severe and complex obesity, to bariatric surgery. However, although there are clear care pathways and clinical guidelines for evidence-based practice, there remains no single stakeholder willing to take overall responsibility for obesity care. There is a lack of provision of adequate services characterised by a noticeable 'postcode lottery', and little political will to change the obesogenic environment.

Abstract
The purpose of this study was to determine the effectiveness of a systematic, explicit, intensive Tier 3 (tertiary) intervention on the mathematics performance of students in second grade with severe mathematics difficulties. A multiple-baseline design across groups of participants showed improved mathematics performance on number and operations concepts and procedures, which are the foundation for later mathematics success. In the previous year, 12 participants had experienced two doses (first and second semesters) of a Tier 2 intervention. In second grade, the participants continued to demonstrate low performance, falling below the 10th percentile on a researcher-designed universal screener and below the 16th percentile on a distal measure, thus qualifying for the intensive intervention. A project interventionist, who met with the students 5 days a week for 10 weeks (9 weeks for one group), conducted the intensive intervention. The intervention employed more intensive instructional design features than the previous Tier 2 secondary instruction, and also included weekly games to reinforce concepts and skills from the lessons. Spring results showed significantly improved mathematics performance (scoring at or above the 25th percentile) for most of the students, thus making them eligible to exit the Tier 3 intervention.

Abstract
A multidisciplinary Tier 3 weight management service in primary care recruited patients with a body mass index ≥40 kg·m(-2) , or 30 kg·m(-2) with obesity-related co-morbidity to a 1-year programme. A cohort of 230 participants was recruited and evaluated using the National Obesity Observatory Standard Evaluation Framework. The primary outcome was weight loss of at least 5% of baseline weight at 12 months. Diet was assessed using the two-item food frequency questionnaire, activity using the General Practice Physical Activity questionnaire and quality of life using the EuroQol-5D-5L questionnaire. A focus group explored the participants' experiences. Baseline mean weight was 124.4 kg and mean body mass index was 44.1 kg·m(-2) . A total of 102 participants achieved 5% weight loss at 12 months. The mean weight loss was 10.2 kg among the 117 participants who completed the 12-month programme. Baseline observation carried forward analysis gave a mean weight loss of 5.9 kg at 12 months. Fruit and vegetable intake, activity level and quality of life all improved. The dropout rate was 14.3% at 6 months and 45.1% at 1 year. Focus group participants described high levels of satisfaction. It was possible to deliver a Tier 3 weight management service for obese patients with complex co-morbidity in a primary care setting with a full multidisciplinary team, which obtained good health outcomes compared with existing services.
