Building and tanning in the 18th and 19th centuries: an analysis of cattle horncores from Greenwich High Road (London)

The assemblage from Greenwich High Road has interesting implications for our understanding of 18th and early 19th century tanneries and also of the use of bones as building material. The study of the age at death of the animals revealed that the horncores are mostly from fully adult individuals, probably culled draught animals. This hypothesis is supported by biometrical analysis. The comparison of the Greenwich horncores with modern data and archaeological evidence suggests that the Greenwich assemblage is predominantly composed of oxen. The horncores were used to line a drain on the site and are likely to represent waste material resulting from the activities that took place in the nearby tannery. Skins and horns were removed for craft purposes while the bony cores, with no economic value, were simply used as cheap and ready material to help the construction of the drain

Challenges to undertaking randomised trials with looked after children in social care settings.

BACKGROUND: Randomised controlled trials (RCTs) are widely viewed as the gold standard for assessing effectiveness in health research; however many researchers and practitioners believe that RCTs are inappropriate and un-doable in social care settings, particularly in relation to looked after children. The aim of this article is to describe the challenges faced in conducting a pilot study and phase II RCT of a peer mentoring intervention to reduce teenage pregnancy in looked after children in a social care setting. METHODS: Interviews were undertaken with social care professionals and looked after children, and a survey conducted with looked after children, to establish the feasibility and acceptability of the intervention and research design. RESULTS: Barriers to recruitment and in managing the intervention were identified, including social workers acting as informal gatekeepers; social workers concerns and misconceptions about the recruitment criteria and the need for and purpose of randomisation; resource limitations, which made it difficult to prioritise research over other demands on their time and difficulties in engaging and retaining looked after children in the study. CONCLUSIONS: The relative absence of a research infrastructure and culture in social care and the lack of research support funding available for social care agencies, compared to health organisations, has implications for increasing evidence-based practice in social care settings, particularly in this very vulnerable group of young people

Adolescents' experience of comments about their weight – prevalence, accuracy and effects on weight misperception

<p>Abstract</p> <p>Background</p> <p>Weight comments are commonly received by adolescents, but the accuracy of the comments and their effects on weight misperception are unclear. We assessed the prevalence and accuracy of weight comments received by Chinese adolescents from different sources and their relation to weight misperception.</p> <p>Methods</p> <p>In the Hong Kong Student Obesity Surveillance (HKSOS) project 2006–07, 22612 students aged 11–18 (41.5% boys) completed a questionnaire on obesity. Students responded if family members, peers and professionals had seriously commented over the past 30 days that they were "too fat" or "too thin" in two separate questions. The accuracy of the comments was judged against the actual weight status derived from self-reported height and weight. Self-perceived weight status was also reported and any discordance with the actual weight status denoted weight misperception. Logistic regression yielded adjusted odd ratios for weight misperception by the type of weight comments received.</p> <p>Results</p> <p>One in three students received weight comments, and the mother was the most common source of weight comments. Health professional was the most accurate source of weight comments, yet less than half the comments were correct. Adolescents receiving incorrect comments had increased risk of having weight misperception in all weight status groups. Receiving conflicting comments was positively associated with weight misperception among normal weight adolescents. In contrast, underweight and overweight/obese adolescents receiving correct weight comments were less likely to have weight misperception.</p> <p>Conclusion</p> <p>Weight comments, mostly incorrect, were commonly received by Chinese adolescents in Hong Kong, and such incorrect comments were associated with weight misperception.</p

Metabolic syndrome in overweight children from the city of Botucatu - São Paulo State - Brazil: agreement among six diagnostic criteria

<p>Abstract</p> <p>Background</p> <p>The metabolic syndrome has been described in children; however, a standard criterion has not been established for its diagnosis. Also, few studies have been conducted to specifically observe the possible existence of agreement among the existing diagnostic criteria. The purpose of the study is to evaluate agreement concerning prevalence rates of the metabolic syndrome diagnosed by six different criteria in overweight schoolchildren in the city of Botucatu - SP -Brazil.</p> <p>Methods</p> <p>This is a cross-sectional study on 128 overweight schoolchildren. Clinical examination included anthropometry, pubertal staging evaluation, and blood pressure. Triacylglycerol, glycemia, HDL-cholesterol, insulin levels, and HOMA-IR were determined. The Kappa index, the Mann-Whitney test and the chi-square test were used for statistical analysis.</p> <p>Results</p> <p>The prevalence of the metabolic syndrome varied from 10 to 16.5% according to different diagnostic criteria. Results were similar for boys and girls and pubertal stage. Great agreement was observed among the six different diagnostic criteria for the metabolic syndrome.</p> <p>Conclusions</p> <p>Different diagnostic criteria, when adopted for subjects with similar demographic characteristics, generate similar and compatible prevalence. Results suggest that it is possible to adopt any of the analyzed criteria, and the choice should be according to the components available for each situation.</p

Age and season of pig slaughter at Late Neolithic Durrington Walls (Wiltshire, UK) as detected through a new system for recording tooth wear

The recording of tooth wear is essential for the investigation of age in zooarchaeological assemblages, but most tooth wear methodologies apply only to mandibular teeth, thereby neglecting potentially valuable maxillary data. The large sample of pig maxillary jaws and teeth recovered at Durrington Walls has provided the opportunity to design a new recording method for maxillary as well as mandibular jaws. Work on previously excavated animal bone material from Durrington Walls (Albarella and Payne, 2005) suggested the possibility of seasonal pig killing at the site, but the issue has not, until now, been explored in detail. This paper therefore has a dual purpose: to describe the new method for recording tooth wear on pig teeth; and to use the new information from both the mandibular and maxillary teeth to explore pig age at death and seasonality at Durrington Walls. The results provide evidence of differential deposition of pigs of different ages at Durrington Walls, with one midden context containing younger pigs brought to the site to provide meat for predominately winter-based feasting events, and other contexts containing remains of older pigs (mainly in their second year) deposited in both domestic and more public locales also predominantly in winter. The study highlights the usefulness of maxillary teeth for our understanding of past systems of pig exploitation as well as the desirability of recording their wear in animal bone assemblages

Comparison of metabolic syndrome prevalence using six different definitions in overweight pre-pubertal children enrolled in a weight management study

Objectives: To assess the implications of variation in Metabolic Syndrome (MS) definition (biochemical and anthropometric indicators) on MS prevalence estimates in a population of overweight and mildly obese children. Design: Cross-sectional study Subjects: Ninety-nine (64 girls) overweight or mildly obese, but otherwise healthy, pre-pubertal 6 to 9 year olds recruited for a randomised controlled trial of weight management Measures: Height, weight and waist circumference were measured with BMI and waist z-scores calculated. Fasting cholesterol and fractions, glucose and insulin were measured, together with systolic and diastolic blood pressure (BP). Anthropometric and metabolic indicators were classified as normal or elevated using adult or child-specific cut points with clustering of MS indicators also assessed using 2 adult and 3 child-specific definitions. Results: Zero to 4% of subjects were classified with MS when adult definitions were applied. This increased to between 39-60% using child-specific definitions, varying according to whether hyperinsulinaemia was central to the MS classification. Systolic BP, triglycerides, total cholesterol, high density lipoprotein cholesterol and waist z-score increased across insulin quartiles (p<0.05). The use of body mass index and waist circumference in the MS definition classified the same subjects. Conclusions: The classification of MS in children depends strongly on the definition chosen, with MS prevalence estimates higher if insulin is part of the definition and child-specific cut points for metabolic indicators are used. Hyperinsulinaemia and MS are common consequences of childhood obesity but they are not commonly part of the assessment or management plan for weight management in children. There is a need for the establishment of normal insulin ranges and consistent definition of MS in childhood and adolescence
