Abstract
BACKGROUND Obese children and adolescents often exhibit progressively declining motor skills. To support young obese patients adequately, it is necessary to assess their individual physical and motor abilities, taking the degree of obesity into account. PATIENTS A total of 5 924 children and adolescents (mean age: 12.7±2.5 years, range 6.0-18.0 years, 3 195 girls) were examined in a standardised multicentre evaluation survey (APV). Fitness parameters were correlated with age- and gender-specific BMI-SDS (Standard Deviation Score) Methods: Anthropometric data were collected and patients performed the modified Munich fitness test (mMFT: maximal power, coordination, trunk flexibility) and a 6-min walk-test (aerobic endurance capacity). RESULTS 33% of patients were extremely obese (BMI>99.5th percentile). Mean BMI-SDS was + 2.32±0.53 (♀-Δ=+ 0.06; p<0.001). The data indicated significant negative correlations between BMI-SDS and selected components of motor performance, especially maximal power (r=- 0,134), and particularly aerobic endurance capacity (r=- 0,214; all p<0.001). Motor performance was significantly below average (n=27 473, 6-18 years), especially among extremely obese patients. Performance in all motor tasks was lower in girls compared to boys, except for trunk flexibility (p<0.001). CONCLUSION Correlations were found between BMI-SDS and motor performance. Extremely obese patients and obese girls showed the most pronounced motor deficits. These results emphasize the importance of standardized evaluation of individual motor performance in children and adolescents with obesity.

Abstract
OBJECTIVE Brain-derived neurotrophic factor (BDNF) plays a fundamental role in brain development; additionally, it is involved in various aspects of cerebral function, including neurodegenerative and psychiatric diseases. Involvement of BDNF in parturition has not been investigated. The aim of our study was to analyze determinants of umbilical cord BDNF (UC-BDNF) concentrations of healthy, term newborns and their respective mothers. METHODS This cross-sectional prospective study was performed at a tertiary referral center. Maternal venous blood samples were taken on admission to labor ward; newborn venous blood samples were drawn from the umbilical cord (UC), before delivery of the placenta. Analysis was performed with a commercially available immunoassay. Univariate analyses and stepwise multivariate regression models were applied. RESULTS 120 patients were recruited. UC-BDNF levels were lower than maternal serum concentrations (median 641 ng/mL, IQR 506 vs. median 780 ng/mL, IQR 602). Correlation between UC- and maternal BDNF was low (R=0.251, p=0.01). In univariate analysis, mode of delivery (MoD), gestational age (GA), body mass index at delivery, and gestational diabetes were determinants of UC-BDNF (MoD and smoking for maternal BDNF, respectively). Stepwise multivariate regression analysis revealed a model with MoD and GA as determinants for UC-BDNF (MoD for maternal BDNF). CONCLUSIONS MoD and GA at delivery are determinants of circulating BDNF in the mother and newborn. We hypothesize that BDNF, like other neuroendocrine factors, is involved in the neuroendocrine cascade of delivery. Timing and mode of delivery may exert BDNF-induced effects on the cerebral function of newborns and their mothers.

Abstract
BACKGROUND Current guidelines for the prevention of obesity in childhood and adolescence are presented. METHODS A literature search was performed in Medline via PubMed, and appropriate studies were analysed. RESULTS Programs to prevent childhood obesity were to date mainly school-based. Effects were limited to date. Analyses tailored to different age groups show that prevention programs have the best effects in younger children (< 12 years). Evidence based recommendations for preschool- and early school age imply the need for interventions addressing parents and teachers alike. During adolescence, school-based interventions were most effective when adolescents were directly addressed. To date, obesity prevention programs have mainly focused on behavior oriented prevention. Recommendations for condition oriented prevention have been suggested by the German Alliance of Non-communicable Diseases and include one hour of physical activity at school, promotion of healthy food choices by taxing unhealthy foods, mandatory quality standards for meals at kindergarten and schools as well as a ban on unhealthy food advertisement addressing children. CONCLUSION Behavior oriented prevention programs showed hardly any or only limited effects in the long term. Certain risk groups for the development of obesity are not reached effectively by available programs. Due to the heterogeneity of available studies, universally valid conclusions cannot be drawn. The combination with condition oriented prevention, which has to counteract on an obesogenic environment, is crucial for sustainable success of future obesity prevention programs.

Abstract
Near-fields of non-resonantly laser-excited nanostructures enable strong localization of ultrashort light fields and have opened novel routes to fundamentally modify and control electronic strong-field processes. Harnessing spatiotemporally tunable near-fields for the steering of sub-cycle electron dynamics may enable ultrafast optoelectronic devices and unprecedented control in the generation of attosecond electron and photon pulses. Here we utilize unsupported sub-wavelength dielectric nanospheres to generate near-fields with adjustable structure and study the resulting strong-field dynamics via photoelectron imaging. We demonstrate field propagation-induced tunability of the emission direction of fast recollision electrons up to a regime, where nonlinear charge interaction effects become dominant in the acceleration process. Our analysis supports that the timing of the recollision process remains controllable with attosecond resolution by the carrier-envelope phase, indicating the possibility to expand near-field-mediated control far into the realm of high-field phenomena. The localized enhancement of laser light in optical near-fields of nanostructures enables the steering of ultrafast electronic motion. Here, the authors employ field propagation in nanospheres to obtain directional tunability and attosecond control of near-field-induced strong-field photoemission.

Abstract
INTRODUCTION Regular physical activity (RPA) is a major therapeutic recommendation in children and adolescents with type 2 diabetes mellitus (T2DM). We evaluated the association between frequency of RPA and metabolic control, cardiovascular risk factors, and treatment regimes. METHODS The Pediatric Quality Initiative (DPV), including data from 225 centers in Germany and Austria, provided anonymous data of 578 patients (10-20 yr; mean 15.7 ± 2.1 yr; 61.9% girls) with T2DM. Patients were grouped by the frequency of their self-reported RPA per week: RPA 0, none; RPA 1, 1-2×/wk; RPA 2, >2×/wk. RESULTS The frequency of RPA ranged from 0 to 9×/wk (mean 1.1×/wk ±1.5). 55.7% of the patients reported no RPA (58.1% of the girls). Hemoglobin A1c (HbA1c) differed significantly among RPA groups (p < 0.002), being approximately 0.8 percentage points lower in RPA 2 compared to RPA 0. Body mass index (BMI-SDS) was higher in the groups with less frequent RPA (p < 0.00001). Multiple regression analysis revealed a negative association between RPA and HbA1c (p < 0.0001) and between RPA and BMI-SDS (p < 0.01). The association between RPA and high density lipoprotein (HDL)-cholesterol was positive (p < 0.05), while there was no association to total cholesterol, low density lipoprotein (LDL)-cholesterol or triglycerides. Approximately 80% of the patients received pharmacological treatment (oral antidiabetic drugs and/or insulin) without differences between RPA groups. CONCLUSION More than half of the adolescents with T2DM did not perform RPA. Increasing physical activity was associated with a lower HbA1c, a lower BMI-SDS, a higher HDL-cholesterol, but not with a difference in treatment regime. These results suggest that regular exercise is a justified therapeutic recommendation for children and adolescents with T2DM.

Abstract
AIM The prevalence of obesity and motor deficits in children is on the rise in western industrialized countries. Due to the negative health related consequences, effective early preventive measures are of urgent need. In the present study the effects of the kindergarten-based low-threshold interventions "Kindergarten Mobile (KiMo)", "Ball and Pear (BP)" and "Nursery Fit (NF)" were determined. METHODS One thousand five hundred ten children (53.4% male) participated in the study (age: 4.7 ± 0.9 years, height: 108.3 ± 7.9cm, weight: 19.1 ± 3.6 kg, BMI: 16.1±1.6kg/m²). The children were divided in the groups KiMo (N.=690), BP (N.=74), NF-P (N.=95), NF-NP (N.=289) and CG (N.=362). Anthropometric data and motor abilities were assessed at T1 (baseline) and T2 (follow-up after 6 months). The interventions included an information session for parents/educators, where key guidelines for a healthy lifestyle were communicated and individual fitness passes were handed over (KiMo, NF-P, NF-NP), respectively an instructed activity lesson once per week (BP, NF-P). RESULTS The results showed a decrease of the BMI in the groups KiMo (-0.1 ± 0.6 kg/m²), NF-P (-0.1 ± 0.7 kg/m²) and NF-NP (-0.2 ± 0.6 kg/m²; each P<0.001 in comparison to the CG) and an increase in the group BP (0.1 ± 0.5 kg/m²; P=0.998 in comparison to the CG). Inconsistent results were shown in all groups regarding motor abilities. CONCLUSION To date, no evidence-based recommendations concerning the optimal procedure for health promotion at pre-school age can be concluded. It seems assured, that the entire social environment of children has to be involved in the prevention of overweight and motor deficits, including parents, educators and pediatricians.

Abstract
It has been demonstrated that alterations of adipocytokines can alter immune status in type 2 diabetes. The present study investigated changes of adipocytokine plasma concentrations and cellular immune status in overweight men, suffering from non-insulin dependent type 2 diabetes (n=14, age 61.0±8.7 years, BMI 31.1±3.5 kg/cm2). Subjects underwent a 3 months endurance exercise intervention (twice per week for up to 45 min) cycling at a heart rate corresponding to a 2 mmol/l lactate threshold. Before and after the intervention testing for adipocytokines (leptin, adiponectin, resistin) and cellular immune status (including T memory-cells and regulative T-cells) was performed by RIA and FACS accordingly.The exercise intervention improved anthropometric and metabolic parameters of all subjects. We observed a significant decline for resistin and for the CD19+ B-cells. The CD4+CD25+CD127low Treg-cells decreased, however not statistically significant. All other parameters remained unchanged.In conclusion, even though only training twice a week, the exercise affected parts of the cellular immune system as well as resistin levels in men suffering from non-insulin dependent type 2 diabetes.

Abstract
The present study analyzes the oxidative stress situation in the skeletal muscle of overweight/obese men suffering from non-insulin-dependent type 2 diabetes mellitus [T2DM, n=16, years=61±7, body mass index (BMI)=31±4 kg/m(2) ] and BMI-matched non-diabetic male control subjects (CON, n=7, years=53±6, BMI=30±4 kg/m(2) ). Furthermore, it investigates whether physical training can alter the skeletal muscle antioxidative capacity of T2DM patients at rest. Molecule content analyses (immunohistochemical stainings) of 8-iso-prostaglandin-F2α (8-Iso-PGF), superoxide dismutase-2 (SOD2), glutathione peroxidase-1 (GPX1), peroxiredoxin isoforms (PRDX 1-6) and heat-shock-protein-70 (HSP70) were performed in biopsies taken from the vastus lateralis muscle. Under basal conditions, 8-Iso-PGF was significantly decreased in T2DM patients (-35.7%), whereas PRDX2 and PRDX6 were significantly increased relative to CON (+82.6%; +82.3%). Differences were neither observed in SOD2 nor in GPX1 or PRDX1, 3, 4, 5 density. Regular physical activity (moderate endurance or resistance training twice a week for 3 months) did not alter PRDX1, 2, 3, 4, 6 in the skeletal muscle of T2DM patients, but significantly increased SOD2 (+65.9%), GPX1 (+62.4%), PRDX5 (+37.5%), and HSP70 (+48.5%). Overweight/obese men with non-insulin-dependent T2DM exhibit up-regulated cytosolic peroxiredoxin contents relative to BMI-matched controls. Regular training further up-regulates cytosolic and mitochondrial antioxidative enzymes in T2DM patients and improves their cellular protection systems. This may contribute to a retardation of the disease's progression.

Abstract
AIM Our objective was to examine the cost-effectiveness of disease management programs (DMPs) for type 2 diabetes mellitus (T2DM) taking into account their life prolonging effect. METHODS We compared real life costs in 19,888 propensity score matched pairs of T2DM DMP participants and T2DM patients in routine care (RC) according to sickness funds data. We estimated mean annual costs for survivors, last year of life costs for decedents, the influence of ageing on costs, incremental cost-effectiveness ratio and effects on hospitalization. RESULTS Annual costs for survivors were 3,318€ (DMP) and 3,570€ (RC). The mean costs in the last year of life were 16,911€ (DMP) and 15,763€ (RC). Ageing had a cost triggering effect for survivors (30€/36€ per year in DMP-/RC-group; p<0.001) and a cost decreasing effect in the last year of life (546€/483€ per year in DMP-/RC-group; p<0.001). The incremental cost-effectiveness ratio of the DMP vs. RC was -1396€ per life-year gained. Hospitalizations increased with age in case of survival and decreased with age in case of death but were always lower in the DMP-group. CONCLUSION Despite increase in costs due to longer life DMPs are cost-effective.
