Abstract
We suggest a reconsideration of the role of 'attachment orientation' in the context of eating disorders and paediatric diabetes. Attachment orientation is a psychological construct that describes a relatively stable set of expectations and behaviours an individual relies upon in managing relationships. There is considerable evidence of an association between attachment orientation and the development and maintenance of disordered eating in individuals without diabetes, though evidence is more scant in populations with diabetes. We discuss the underpinning theory and critically examine the existing literature for the relationship between attachment orientation and disordered eating in paediatric diabetes. Finally, we draw on adjacent literatures to highlight potential future directions for research should this area be revisited. Overall, we contextualise our discussion in terms of patient-centred, holistic care that addresses the mind and body (i.e., our discussion of attachment orientation assumes a psycho-biological approach).

The prevalence of undiagnosed Prediabetes/type 2 diabetes, prehypertension/hypertension and obesity among ethnic groups of adolescents in Western Canada. BMC Pediatr 2020; 20:31. [PMID: 31973728 PMCID: PMC6979336 DOI: 10.1186/s12887-020-1924-6] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2019] [Accepted: 01/14/2020] [Indexed: 12/14/2022] Open
Abstract
Background An increased incidence of type 2 diabetes in youth is occurring worldwide. While diverse ethnic groups are disproportionately affected by type 2 diabetes, studies that explore ethnic differences and undiagnosed prediabetes/type 2 diabetes in adolescents are scarce. This paper compares the prevalence of undiagnosed prediabetes and type 2 diabetes and the associated risk factors among various ethnic groups of adolescents living in Western Canada. Methods The data for this study were derived from two previous studies in which 396 adolescents, aged 14 to 19 years and living in a western Canadian province, were screened for undiagnosed prediabetes, diabetes, and any associated risk factors. Risk was determined by demographics, family history, anthropometric measurements (body mass index, BMI), blood pressure (BP), and HbA1c. Descriptive and inferential statistics (SPSS) were used to establish both risk and prevalence for prediabetes and type 2 diabetes. Chi-square analyses were done to determine if the risk factors occurred at higher frequencies in certain ethnicities. Results Based on BP, BMI, and HbA1c measurements, several statistically significant differences were identified in relation to ethnicity. Many of the adolescents had increased HbA1c levels, with 27.3% considered high risk and 2.3% in the prediabetes range; these high risk and prediabetes groups were heavily represented by Filipino (46%), Indigenous (22%), and European (10%) adolescents. Notable prevalence of prehypertension (17.7%) and hypertension (21.7%) were reported in European (59%) followed by Filipino (50%) and Indigenous (26%) adolescents. Higher numbers of adolescents in the European and Filipino ancestry groups had two or more risk factors (BP, BMI, & HbA1c) for developing type 2 diabetes in relation to the adolescents from the Indigenous group. Conclusions Ethnic adolescent groups demonstrate a notable prevalence of undiagnosed prediabetes and type 2 diabetes. Specifically, a significant number of Filipino adolescents had both increased HbA1c and blood pressure that has gone undetected. Earlier onset of type 2 diabetes is congruent with an increased risk of developing diabetes-associated complications and, ultimately, diabetes-related morbidity and mortality at a younger age. Future studies should explore how genetic and/or environmental factors among ethnic groups may contribute to early onset hypertension and prediabetes/type 2 diabetes.

Abstract
AIM Diabetes in children is becoming more prevalent in some countries. However, in most countries, little is known about the epidemiology of this disease. This study is aimed at estimating the prevalence of type 1 and type 2 diabetes and prediabetes among children in Vietnam and examining factors associated with the conditions. METHODS A total of 2880 students aged 11-14 years old were recruited for the survey, using a school-based and nationally representative sampling frame. Capillary blood samples of participants were collected to measure fasting glucose level, using glucose meter OneTouch Verio Pro+. Diabetes and impaired fasting plasma glucose were initially diagnosed based on the cut-off points of the American Diabetes Association criteria. Diabetes status and type of diabetes of participants were confirmed at a hospital. Additionally, anthropometric and blood pressure measurements were conducted following a standardized procedure. Multivariate logistic regression was used to examine the association between outcome and independent variables. RESULTS The overall prevalence of diabetes among the participants was 1.04‰ (three cases), with 2 cases (0.75‰) diagnosed with type 1 diabetes (one known and one newly diagnosed) and 1 case newly diagnosed with type 2 diabetes (0.35‰). The prevalence of impaired fasting glucose was 6.1%. Body mass index, place of residence, and age were found to be significantly associated with the impaired fasting glucose condition in participants. CONCLUSION The prevalence of type 1 and type 2 diabetes in children in Vietnam is lower than that in some other countries reported recently. However, there is a high prevalence in impaired fasting glucose, requiring attention from policymakers to take action to prevent the occurrence of the epidemic of type 2 diabetes in children in the future.

Abstract
PURPOSE OF REVIEW Very little is known about the occurrence of type 1 diabetes (T1DM) in resource-poor countries and particularly in their rural hinterlands. RECENT FINDINGS Studies of the epidemiology of T1DM in Ethiopia and similar countries in sub-Saharan Africa show that the pattern of presenting disease differs substantially from that in the West. Typically, the peak age of onset of the disease is more than a decade later with a male excess and a low prevalence of indicators of islet-cell autoimmunity. It is also associated with markers of undernutrition. These findings raise the question as to whether the principal form of T1DM seen in these resource-poor communities has a different pathogenesis. Whether the disease is a direct result of malnutrition or whether malnutrition may modify the expression of islet-cell autoimmunity is unclear. However, the poor prognosis in these settings underlines the urgent need for detailed clinical and epidemiological studies.

Abstract
AIMS In this study, we investigated whether two common variants (rs3088442G>A and rs2292334G>A) in the organic cation transporter 3 (OCT3) gene, a high-capacity transporter widely expressed in various tissues, affect susceptibility to type 2 diabetes (T2D) in patients newly diagnosed with T2D. METHODS We performed a study with 150 newly diagnosed patients with T2D and 152 controls. The genetic analyses were performed using the restricted fragment length polymorphism (RFLP) after PCR amplification. RESULTS For the rs3088442G>A variant, A allele carriers had a significantly lower odds ratio (OR) vs. GG homozygotes in the BMI <30 kg/m2 group (OR = 0.23, p <0.001) compared with the BMI ≥30 kg/m2 group (OR = 0.67, p = 0.34). When ORs were adjusted for BMI, age, sex, and blood pressure, our findings showed that the overexpression of the A allele of the rs3088442G>A variant was associated with a decreased risk of T2D (OR = 0.016, p <0.001). A Bayesian logistic model revealed that the interaction of two variants studied were significantly associated with a decreased risk of T2D (OR = 0.61, p = 0.03). CONCLUSIONS The present study has identified the protective effect of the variant rs3088442G>A in the 3'-untranslated region of the OCT3 gene in susceptibility to T2D, and that the protective role is maintained in the presence of risky alleles of the variant rs2292334G>A. The association of the A allele of rs3088442G>A with T2D become weaker in obese people than that of non-obese. If confirmed in other populations, the rs3088442G>A variant as a genetic marker may potentially assist in the identification of individuals at an increased risk of T2D.

Abstract
Type 1 diabetes is one of the most common chronic childhood diseases, while type 2 diabetes in children is increasing at alarming rates globally. Against this backdrop, the school is a critical environment for children with diabetes. They continue to face barriers to education that may lead to depression, poor academic performance, and poor quality of life. To address these challenges, diabetes interventions have been implemented in school and the goal was to systematically review these interventions and their outcomes between 2000 and 2013. Fifteen studies were included in the narrative synthesis. Education of school personnel was the main focus before 2006. Studies reported gains in knowledge and perceived confidence of school staff. Since 2006, more comprehensive interventions have been developed to promote better care coordination and create a safe school environment. These studies reported improved diabetes management and quality of life of students. Assessment tools varied and study design included randomized controlled trials, quantitative and qualitative methods. Although many of the studies reported a significant difference in the parameters measured, it was not possible to determine optimal ways to improve the health, quality of life and academic performance of children with diabetes, given the disparity in scope, assessment tools and measured outcomes. Experimental designs, longer follow-up studies, larger sample sizes, and a higher number of participating schools are critical issues to consider in future studies. Most of the research was conducted in North America and further research is needed in other parts of the world. Significance for public health Diabetes is one of the most common chronic childhood diseases; both type 1 and type 2 diabetes are increasing in children globally. Against this backdrop, the school is a critical environment for children with diabetes. This systematic literature review on school-based diabetes interventions and their outcomes demonstrates that increasing efforts are being made to improve diabetes care and create a safe school environment. Studies reported gains in knowledge and confidence of school staff, as well as improved health and quality of life of students. Given the disparity of the assessment tools used, it was not possible to determine optimal ways to improve the health, quality of life and academic performance of children with diabetes. Future evaluations should include experimental designs, longer follow-up studies, and larger sample sizes. School-based diabetes interventions and solid evaluations will contribute to improving diabetes school policies and ensuring children with diabetes have the same educational opportunities as other children.

Peroxynitrite modified DNA presents better epitopes for anti-DNA autoantibodies in diabetes type 1 patients. Cell Immunol 2014; 290:30-8.

Abstract
Peroxynitrite (ONOO(-)), formed by the reaction between nitric oxide (NO) and superoxide (O2(-)), has been implicated in the etiology of numerous disease processes. Peroxynitrite interacts with DNA via direct oxidative reactions or via indirect radical-mediated mechanism. It can inflict both oxidative and nitrosative damages on DNA bases, generating abasic sites, resulting in the single strand breaks. Plasmid pUC 18 isolated from Escherichiacoli was modified with peroxynitrite, generated by quenched flow process. Modifications incurred in plasmid DNA were characterized by ultraviolet and fluorescence spectroscopy, circular dichroism, HPLC and melting temperature studies. Binding characteristics and specificity of antibodies from diabetes patients were analyzed by direct binding and inhibition ELISA. Peroxynitrite modification of pUC 18 plasmid resulted in the formation of strand breaks and base modification. The major compound formed when peroxynitrite reacted with DNA was 8-nitroguanine, a specific marker for peroxynitrite induced DNA damage in inflamed tissues. The concentration of 8-nitroguanine was found to be 3.8 μM. Sera from diabetes type 1 patients from different age groups were studied for their binding to native and peroxynitrite modified plasmid. Direct binding and competitive-inhibition ELISA results showed higher recognition of peroxynitrite modified plasmid, as compared to the native form, by auto-antibodies present in diabetes patients. The preferential recognition of modified plasmid by diabetes autoantibodies was further reiterated by gel shift assay. Experimentally induced anti-peroxynitrite-modified plasmid IgG was used as a probe to detect nitrosative lesions in the DNA isolated from diabetes patients.

Abstract
BACKGROUND AND OBJECTIVES ESRD in the young represents a heavy burden to patients, families, and health care systems. This nationwide retrospective study characterized the incidence of ESRD and analyzed diagnoses associated with renal survival in the young population in Taiwan. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Through use of Taiwan's National Health Insurance Research Database, the population of young patients (age<30 years, including children and young adults) with ESRD between January 1998 and December 2009 were enrolled. The medical claims were used to derive the date when the cause of ESRD was first determined. The medical data were reviewed and the renal survival time (time from first diagnosis of the cause to the start of ESRD) was calculated by experts, including clinical physicians and a large-database specialist. RESULTS The incidence rate of ESRD in the young population was high compared with the worldwide rate at 21.1 per million person-years, whereas the incidence in the pediatric group was still similar to that in other countries at 10.3 per million person-years. A total of 2304 patients with new-onset ESRD and identified renal diseases during the study period were enrolled. All preschool-age patients (100%) began receiving peritoneal dialysis as their initial treatment for ESRD. The leading causes, which varied by sex and onset age, were glomerulonephropathy followed by hypertension for the young adult group and glomerulonephropathy followed by congenital anomalies of the kidney and urinary tract (CAKUT) for the pediatric group. Renal survival was cause-dependent. The median overall renal survival duration was 0.8 year (interquartile range [IQR], 0.7-3.5 years). CAKUT-related ESRD had the longest progression time (median renal survival, 16.0 years; IQR, 10.7-23.5 years); glomerulonephropathy progressed more rapidly into ESRD and had the shortest median renal survival of 0.5 year (IQR, 0.1-2.7 years). CONCLUSIONS The incidence and causes of ESRD greatly differ between pediatric patients and young adults. Moreover, renal survival in the young population markedly varies depending on the cause of renal disease.

Abstract
The worldwide increase in the prevalence of Diabetes mellitus (DM) has highlighted the need for increased research efforts into treatment options for both the disease itself and its associated complications. In recent years, mesenchymal stromal cells (MSCs) have been highlighted as a new emerging regenerative therapy due to their multipotency but also due to their paracrine secretion of angiogenic factors, cytokines, and immunomodulatory substances. This review focuses on the potential use of MSCs as a regenerative medicine in microvascular and secondary complications of DM and will discuss the challenges and future prospects of MSCs as a regenerative therapy in this field. MSCs are believed to have an important role in tissue repair. Evidence in recent years has demonstrated that MSCs have potent immunomodulatory functions resulting in active suppression of various components of the host immune response. MSCs may also have glucose lowering properties providing another attractive and unique feature of this therapeutic approach. Through a combination of the above characteristics, MSCs have been shown to exert beneficial effects in pre-clinical models of diabetic complications prompting initial clinical studies in diabetic wound healing and nephropathy. Challenges that remain in the clinical translation of MSC therapy include issues of MSC heterogeneity, optimal mode of cell delivery, homing of these cells to tissues of interest with high efficiency, clinically meaningful engraftment, and challenges with cell manufacture. An issue of added importance is whether an autologous or allogeneic approach will be used. In summary, MSC administration has significant potential in the treatment of diabetic microvascular and secondary complications but challenges remain in terms of engraftment, persistence, tissue targeting, and cell manufacture.

Abstract
Diabetes mellitus results in severe cardiovascular complications, and heart disease and failure remain the major causes of death in patients with diabetes. Given the increasing global tide of obesity and diabetes, the clinical burden of diabetes-induced cardiovascular disease is reaching epidemic proportions. Therefore urgent actions are needed to stem the tide of diabetes which entails new prevention and treatment tools. Clinical and pharmacological studies have demonstrated that AngII (angiotensin II), the major effector peptide of the RAS (renin–angiotensin system), is a critical promoter of insulin resistance and diabetes mellitus. The role of RAS and AngII has been implicated in the progression of diabetic cardiovascular complications and AT1R (AngII type 1 receptor) blockers and ACE (angiotensin-converting enzyme) inhibitors have shown clinical benefits. ACE2, the recently discovered homologue of ACE, is a monocarboxypeptidase which converts AngII into Ang-(1–7) [angiotensin-(1–7)] which, by virtue of its actions on the MasR (Mas receptor), opposes the effects of AngII. In animal models of diabetes, an early increase in ACE2 expression and activity occurs, whereas ACE2 mRNA and protein levels have been found to decrease in older STZ (streptozotocin)-induced diabetic rats. Using the Akita mouse model of Type 1 diabetes, we have recently shown that loss of ACE2 disrupts the balance of the RAS in a diabetic state and leads to AngII/AT1R-dependent systolic dysfunction and impaired vascular function. In the present review, we will discuss the role of the RAS in the pathophysiology and treatment of diabetes and its complications with particular emphasis on potential benefits of the ACE2/Ang-(1–7)/MasR axis activation.

Abstract
AIMS/HYPOTHESIS This study aimed to systematically review what has been reported on the incidence and prevalence of type 2 diabetes in children and adolescents, to scrutinise the methodological issues observed in the included studies and to prepare recommendations for future research and surveillances. METHODS PubMed, the Cochrane Database of Systematic Reviews, Scopus, EMBASE and Web of Science were searched from inception to February 2013. Population-based studies on incidence and prevalence of type 2 diabetes in children and adolescents were summarised and methodologically evaluated. Owing to substantial methodological heterogeneity and considerable differences in study populations a quantitative meta-analysis was not performed. RESULTS Among 145 potentially relevant studies, 37 population-based studies met the inclusion criteria. Variations in the incidence and prevalence rates of type 2 diabetes in children and adolescents were mainly related to age of the study population, calendar time, geographical regions and ethnicity, resulting in a range of 0-330 per 100,000 person-years for incidence rates, and 0-5,300 per 100,000 population for prevalence rates. Furthermore, a substantial variation in the methodological characteristics was observed for response rates (60-96%), ascertainment rates (53-99%), diagnostic tests and criteria used to diagnose type 2 diabetes. CONCLUSIONS/INTERPRETATION Worldwide incidence and prevalence of type 2 diabetes in children and adolescents vary substantially among countries, age categories and ethnic groups and this can be explained by variations in population characteristics and methodological dissimilarities between studies.

Abstract
The aim of this study was to analyze body fat anthropometric equations and electrical bioimpedance analysis (BIA) in the prediction of cardiovascular risk factors in eutrophic and overweight adolescents. 210 adolescents were divided into eutrophic group (G1) and overweight group (G2). The percentage of body fat (% BF) was estimated using 10 body fat anthropometric equations and 2 BIA. We measured lipid profiles, uric acid, insulin, fasting glucose, homeostasis model assessment-insulin resistance (HOMA-IR), and blood pressure. We found that 76.7% of the adolescents exhibited inadequacy of at least one biochemical parameter or clinical cardiovascular risk. Higher values of triglycerides (TG) (P = 0.001), insulin, and HOMA-IR (P < 0.001) were observed in the G2 adolescents. In multivariate linear regression analysis, the % BF from equation (5) was associated with TG, diastolic blood pressure, and insulin in G1. Among the G2 adolescents, the % BF estimated by (5) and (9) was associated with LDL, TG, insulin, and the HOMA-IR. Body fat anthropometric equations were associated with cardiovascular risk factors and should be used to assess the nutritional status of adolescents. In this study, equation (5) was associated with a higher number of cardiovascular risk factors independent of the nutritional status of adolescents.

Abstract
Several developments in Western Europe may have contributed to the increased prevalence of dental erosion during the last decades. Exposing children to sour taste at an early age increases the preference for acidic food and drinks later in life. Acidic fruits and beverages became widely available due to economic prosperity. New types of acidic candies were developed, some of which are kept in the mouth for very long times. Children are exposed to intense marketing of these acidic products, which are widely available in supermarkets and school canteens. In the meantime, much less attention has been paid to the development and marketing of less erosive food products.

Abstract
OBJECTIVE Many obese children with unprovoked diabetic ketoacidosis (DKA) display clinical features of type 2 diabetes during follow up. We describe the clinical presentation, autoimmune markers and the long-term course of obese and lean children with DKA. RESEARCH DESIGN AND METHODS We reviewed the medical records on the initial acute hospitalization and outpatient follow-up care of 21 newly diagnosed obese and 20 lean children with unprovoked DKA at Emory University affiliated children's hospitals between 1/2003 and 12/2006. RESULTS Obese children with DKA were older and predominantly male, had acanthosis nigricans, and had lower prevalence of autoantibodies to islet cells and glutamic acid decarboxylase than lean children. Half of the obese, but none of the lean children with DKA achieve near-normoglycemia remission and discontinued insulin therapy during follow-up. Time to achieve remission was 2.2±2.3 months. There were no differences on clinical presentation between obese children who achieved near-normoglycemia remission versus those who did not. The addition of metformin to insulin therapy shortly after resolution of DKA resulted in lower hemoglobin A1c (HbA1c) levels, higher rates of near-normoglycemia remission, and lower frequency of DKA recurrence. Near-normoglycemia remission, however, was of short duration and the majority of obese patients required reinstitution of insulin treatment within 15 months of follow-up. CONCLUSION In contrast to lean children with DKA, many obese children with unprovoked DKA display clinical and immunologic features of type 2 diabetes during follow-up. The addition of metformin to insulin therapy shortly after resolution of DKA improves glycemic control, facilitates achieving near-normoglycemia remission and prevents DKA recurrence in obese children with DKA.

Abstract
BACKGROUND Forty-three percent of New York City's (NYC) school-age children are overweight or obese, placing them at risk for heart disease and type 2 diabetes mellitus (T2DM). OBJECTIVE The objective of this study was to determine if an intensive after-school dance and lifestyle education program would reduce risk factors for heart disease, T2DM, and improve lifestyle choices. SUBJECTS Subject include 64 fourth- and fifth-grade students at an elementary school in NYC. METHODS Students received freestyle dance and lifestyle classes for 16 weeks and were evaluated for changes in body composition, endurance, biochemical measurements, and lifestyle choices. RESULTS Significant improvements in BMI percentiles were found among children in the overweight and obese categories as well as in endurance and biochemical measurements that reflect heart disease and diabetes risk. Improvement was also reported in lifestyle choices. CONCLUSION An intensive after-school dance and lifestyle education program can reduce risk factors for heart disease and T2DM and improve lifestyle choices among elementary school children.

Abstract
OBJECTIVE To assess performance of nonfasting tests to screen children for dysglycemia (prediabetes or diabetes). RESEARCH DESIGN AND METHODS This was a cross-sectional study of 254 overweight or obese (BMI ≥85th percentile) children aged 10-17 years. Subjects came for two visits to a clinical research unit. For visit one, they arrived fasting and a 2-h glucose tolerance test and HbA(1c) and fructosamine testing were performed. For visit two, they arrived nonfasting and had a random plasma glucose, a 1-h 50-g nonfasting glucose challenge test (1-h GCT), and urine dipstick performed. The primary end point was dysglycemia (fasting plasma glucose ≥100 mg/dL or a 2-h postglucose ≥140 mg/dL). Test performance was assessed using receiver operating characteristic (ROC) curves and calculations of area under the ROC curve. RESULTS Approximately one-half of children were female, 59% were white, and 30% were black. There were 99 (39%) cases of prediabetes and 3 (1.2%) cases of diabetes. Urine dipstick, HbA(1c) (area under the curve [AUC] 0.54 [95% CI 0.47-0.61]), and fructosamine (AUC 0.55 [0.47-0.63]) displayed poor discrimination for identifying children with dysglycemia. Both random glucose (AUC 0.66 [0.60-0.73]) and 1-h GCT (AUC 0.68 [0.61-0.74]) had better levels of test discrimination than HbA(1c) or fructosamine. CONCLUSIONS HbA(1c) had poor discrimination, which could lead to missed cases of dysglycemia in children. Random glucose or 1-h GCT may potentially be incorporated into clinical practice as initial screening tests for prediabetes or diabetes and for determining which children should undergo further definitive testing.

Abstract
Diabetes shows a wide range of variation in prevalence around the world and it is expected to affect 300 million by the year 2025. In a prevention framework where banning policies and educational strategies lead the interventions, functional foods (FFs) with their specific health effects could, in the future, indicate a new mode of thinking about the relationships between food and health in everyday life. Functional ingredients, such as stevioside, cinnamon, bitter melon, garlic and onion, ginseng, Gymnema sylvestre and fenugreek, have been addressed for their specific actions towards different reactions involved in diabetes development. New strategies involving the use of FF should be validated through large-scale population trials, considering validated surrogate end points to evaluate the effect of FF in prevention of chronic diseases such as type 2 diabetes mellitus.

Abstract
To evaluate how non-high-density-lipoprotein (non-HDL) is associated with impaired fasting glucose (IFG) and clustered metabolic risk (MR) factors among adolescents, we pooled 2764 adolescents, aged 12-19 years, from the National Health and Nutrition Examination Survey from 3 time periods (1999-2000, 2001-2002, and 2003-2004) who were free of diabetes and had fasted overnight for this analysis. IFG was defined as 100 <or= glucose <or= 125 mg.dL-1. Age- and sex-specific cut-offs were used for 4 MR factors: higher levels of triglycerides, waist circumference, blood pressure, and lower levels of HDL. Clustered MR was defined as having any 2 of the 4 factors. Overall, approximately 11% of adolescents had IFG. The mean level of non-HDL cholesterol was much higher in those with IFG than in those without IFG, with adjustment for certain confounding variables (121.4 vs. 110.1 mg.dL-1; p < 0.05). This difference could still be observed in adolescents with one or more clustered MR factors. However, there were no statistical differences in low-density-lipoprotein (LDL) level. Compared with those who were without IFG and not at high levels of non-HDL - after adjustment for age, sex, race, current smoking, and body mass index - the odds of having clustered MR factors were 1.08 (95% CI, 0.65-1.82) for those with IFG and low non-HDL cholesterol, 3.55 (2.29-5.48) for those without IFG but with high non-HDL cholesterol, and 10.10 (3.67-27.80) for those with both IFG and high non-HDL cholesterol. Moreover, those with IFG and at increased risk of obesity were more likely to have higher levels of non-HDL cholesterol (odds ratio (95% CI): 4.41 (2.28-8.50)), compared with those without IFG and not at increased risk of obesity. In summary, prediabetic adolescents with IFG and high levels of non-HDL cholesterol are more likely to have clustered MR factors. Thus, the levels of non-HDL cholesterol may be an important indicator in monitoring cardiovascular disease risk among adolescents with IFG.

Abstract
Diabetic complications — the long-term damage to various organ systems — are a great cause of mortality and morbidity in both type 1 and type 2 diabetes. There are currently few therapeutic options to prevent or ameliorate these complications. High blood glucose levels and the subsequent metabolic consequences of hyperglycaemia are widely considered the primary event that initiates diabetic complications, although there is accumulating evidence that impaired insulin signalling arising from insulin deficiency and insulin resistance may also have a pathogenic role. Vascular dysfunction is a prominent complication of diabetes that is widely held to underlie damage to organ systems such as the macrovasculature, kidneys, eyes and nerves. Other consequences of diabetes, such as dyslipidaemia and hypertension, are key modifiers of vascular injury and act as accelerators of diabetic complications. Numerous pathogenic mechanisms, including increased polyol pathway flux and mitochondrial activity, activation of protein kinase C and NADPH oxidase and signalling through the receptor for advanced glycation end products (RAGE) pathway, seem to form a central pathogenic axis that is common to most, if not all, of the complications of diabetes. These disorders all promote excess production of pro-oxidative molecules. Organ-specific mechanisms, such as diminished growth factor support and repair pathway activation, must also be considered. Few animal models of diabetic complications faithfully reflect the advanced stages of organ pathology seen in humans. Current models can be viewed as potentially illustrating early biochemical and functional disorders of diabetes that ultimately lead to advanced pathology. New animal models are being developed using both a reductionist approach for examining specific gene products of interest and also by combining diverse molecular and physiological risk factors. Control of blood glucose levels and lipids remains the most meaningful approach for preventing diabetic complications. This strategy is likely to be complemented by a diverse range of more focused therapeutics that have emerged from mechanistic studies in animal models and which are currently in clinical development. Some of these, such as those targeting cardiovascular disease, have the potential to affect several diabetic complications, whereas others focus on intervening in organ-specific pathogenic mechanisms. It is probable that combination therapies aimed at the hyperglycaemia-driven pathogenic axis and also at organ-specific disorders will provide the most effective approach to treating the diverse complications of diabetes.
Long-term diabetes increases the likelihood of developing complications such as macrovascular disease, nephropathy, retinopathy and neuropathy. This Review highlights the range of pathologies that are precipitated by hyperglycaemia and discusses recent developments in preclinical and clinical research for each of these complications. Long-term diabetes increases the likelihood of developing secondary damage to numerous systems, and these complications represent a substantial cause of morbidity and mortality. Establishing the causes of diabetes remains the key step towards eradicating the disease, but the prevention and amelioration of diabetic complications is equally important for the millions of individuals who already have the disease or are likely to develop it before prophylaxis or a cure become routinely available. In this Review, we focus on four common complications of diabetes, discuss the range of pathologies that are precipitated by hyperglycaemia and highlight emerging targets for therapeutic intervention.

Abstract
OBJECTIVES (1) Determine the prevalence of overweight and high blood pressure (BP) among middle and high school students over a 2-year period and, (2) measure the cost and initial outcomes of screening. DESIGN Cost and outcome description using a cross-sectional design sample. The target population was 12- to 19-year-old healthy students attending grades 7 through 12 at 3 proximal schools located in a large urban school district in Texas. RESULTS Of 2,338 students screened, 925 (39.6%) had a body mass index (BMI)>or=85th percentile and 504 (21.6%) had BMIs>or=95th percentile for age and gender. There were 346 students (14.8%) with BMIs>or=85th percentile and systolic blood pressure (SBP)>or=95th percentile for age, gender, and height. The cost of the 2-year screening program was $66,442, and the cost per student was $28. The cost to identify a student with increased BMI or high SBP was $72 and $107, respectively. CONCLUSIONS This study offered an objective framework to examine the cost and outcomes of screening children for overweight and increased BP. The study has implications for discussion and informed decision making about school-based screening for these conditions.

Abstract
Cognitive profiles of 12 schoolboys with obesity were compared with their peers with normal weight. For the cognitive assessment five clinical tasks were selected: digit span memory, Raven's progressive matrices (intelligence), semantic verbal fluency, D2 attention endurance and Wisconsin card sorting test. We found no differences in memory, intelligence and verbal fluency between the two groups. Children with obesity performed worse on D2 and Wisconsin tests. Correlations confirmed relationships between body weight, body mass index, attention and Wisconsin measured perseveration in set-shifting. This suggests that childhood obesity involves cognitive deficits in shifting and attention abilities.

Abstract
Preliminary research suggests that pediatric overweight is associated with increased eating disorder pathology, however, little is known about which overweight youth are most vulnerable to eating disorder pathology. We therefore investigated 122 overweight treatment-seeking youth to describe eating disorder pathology and mental health correlates, and to identify psychopathological constructs that may place overweight youth at increased risk for eating disorder pathology. Youth participated in a comprehensive assessment of eating disorders, mood and anxiety disorders, general psychopathology, and risk variables involving semi-structured clinical interviews and self- and parent-report questionnaires prior to the initiation of weight-loss treatment. Ten youth met criteria for an eating disorder, and over one-third endorsed recent binge eating. Eating disorder pathology was associated with depressive and anxious symptoms (p's<0.001). Structural equation modeling indicated increased negative affect, teasing experience, and thin-ideal internalization, and decreased perfectionism were associated with increased eating disorder pathology. Findings corroborate earlier work indicating that eating disorder pathology is elevated and clinically significant in overweight treatment-seeking youth, bolstering the need for mental health assessment of such individuals. Cross-sectional modeling proposed key variables that relate to eating disorder pathology in overweight treatment-seeking youth, which following prospective replication, may inform the development of effective interventions for overweight and eating disorders.

Abstract
Obesity is increasingly becoming a problem for Western societies, to the extent that politicians, scientists, patient organisations and the media now refer to it as 'the obesity epidemic'. Concerns about the damaging effect of increasing body weight on public health has led to a strong growth in the amount of scientific work on the condition, with the medical professions leading the way. This article discusses that, first of all, scientific evidence for obesity-associated mortality is at best ambiguous, and proposes that at least some of contemporary medical preoccupation with obesity has a moral origin in that it seeks to correct unwanted or immoral behaviour. It then continues to reflect on the effect of the conceptual transformation of healthy children into patients, and concludes with some reflections on the ethical implications of the obesity disease for the wellbeing of children.

Abstract
This study aims to investigate the association between ADD tendency, with or without hyperactivity, and all types of unintentional injuries among adolescents. This study was a population-based health survey utilising a two-stage random cluster sampling design. The study was conducted among high school students in Nanning, the capital city of the Guangxi Province, China. Subjects were recruited from the total population of adolescents who attended high school years 1, 2, and 3 with ages ranging from 13 to 17 years. Information on ADD was collected by trained health professional via personal interviews. Other information, including unintentional injury was collected via a self-report health survey questionnaire. One thousand and twenty-nine (n = 1429) students were recruited with 115 (7.9%) identified as having a high ADD tendency, and 340 (22.6%) reported as having experienced an injury in the last 3 months. After adjusting for other potential confounding factors, results from the logistic regression analyses indicated that adolescents who scored high on the ADD tendency had an increased risk of injury by about 70% as compared to those who scored low (OR = 1.68, 95%CI = 1.18-2.40). ADD tendency has been identified as a potential risk factor of injury among adolescents. Screening for risk factors can be considered as a potential preventive strategy.

Abstract
Type 1 diabetes results from the autoimmune destruction of the insulin producing pancreatic beta-cells. For years, the notion that T-lymphocytes played a crucial role in the disorder's formation was considered such sound dogma, that interest in B-lymphocytes and autoantibodies as pathogenic variables was largely relegated to second-class status. However, much of our knowledge regarding the pathogenesis and natural history of this disease has been afforded by analysis of subjects having type 1 diabetes associated autoantibodies. While autoantibodies to more than two dozen autoantigens have been associated with this disease, a majority of interest has been directed at four autoantibodies; islet cell cytoplasmic (ICA), insulin (IAA), glutamic acid decarboxylase (GADA), and IA2/ICA512 autoantigen (IA2A). These autoantibodies, combined with other metabolic and genetic markers, are extremely effective for predicting eventual development of type 1 diabetes in otherwise healthy individuals. These autoantibodies have also aided in our understanding of disease heterogeneity and suggest that the autoimmune processes underlying type 1 diabetes initiate in the earliest stages of life (e.g., initial autoantibody formation at 9-18 months of age). Additional improvements are needed to more accurately define the time to disease onset, response to therapeutic intervention, the pathogenic features of the autoimmune response, and perhaps even the quantity of residual beta cell function.
