Inelastic mean-free path and mean escape depth of 10-140 eV electrons in SiO2 nanoparticles determined by Si 2p photoelectron yields.

We report on photoelectron spectra of SiO2 nanoparticles (d = 157 ± 6 nm) above the Si 2p threshold in the photon energy range 118-248 eV with electron kinetic energy 10-140 eV and analyze the photoelectron yield as a function of photon energy. Comparison of the experimental results with Monte-Carlo simulations on electron transport allows us to quantify the inelastic mean-free path and mean escape depth of photoelectrons in the nanoparticle samples. The influence of the nanoparticle geometry and electron elastic scattering on photoelectron yields is highlighted. The results show that the previously proposed direct proportionality of the photoelectron signal to the inelastic mean-free path or the mean escape depth does not hold for photoelectron kinetic energies below 30 eV due to the strong influence of electron elastic scattering. The present results deviate for photoelectron kinetic energies below 30 eV from the previously proposed direct proportionality of the photoelectron signal to the inelastic mean-free path or the mean escape depth, which is the result of a strong influence of electron elastic scattering. The presented inelastic mean-free paths and mean escape depths appear to be useful for the quantitative interpretation of photoemission experiments on nanoparticles and for modeling of the experimental results.

Cost-effectiveness of a family-based multicomponent outpatient intervention program for children with obesity in Germany.

OBJECTIVES: Facing an epidemic of childhood obesity and budget constraints, public health administrations are showing an urgent interest in interventions that are both health effective and cost-effective. Thus, this study intends to analyze the return on investment of these existing programs. STUDY DESIGN: All analyses are based on a comprehensive data set from 249 children with obesity and overweight children who participated in the Children's Health InterventionaL Trial (CHILT), an 11-month outpatient multidisciplinary family-based program. METHODS: Cost-effectiveness was assessed by comparing estimated savings associated with a reduction in weight and improvement of obesity-related health parameters with intervention costs. Projected future savings in health care expenditures were modeled on existing research, using estimates of health care costs associated with juvenile obesity and remission thresholds of obesity-related disease. RESULTS: On average, participants achieved a 0.19-unit reduction in the body mass index standard deviation score, showed reduction in their blood pressure values (systolic = -1.76 mmHg, diastolic = -2.82 mmHg), and showed improvement in their high-density lipoprotein (HDL) and low-density lipoprotein (LDL) cholesterol values (HDL = +1.31 mg/dL, LDL = -4.82 mg/dL). The intervention costs were 1799€ per participant, and the benefits of avoided future health care costs varied by individual. On an aggregated level, future savings amounted to between 1859€ and 1926€ per person, translating into a return on investment of 3.3-7.0%. CONCLUSIONS: This study shows that a multicomponent obesity intervention, such as the CHILT, not only results in weight loss and improves important health parameters but also is cost-effective.

[The pathologist and "short-term rector" Albert Dietrich (1873-1961) and his ambivalent relationship with the Nazi regime : Not Nazi enough? German version]. / Der Pathologe und "Kurzzeitrektor" Albert Dietrich (1873­1961) und sein ambivalentes Verhältnis zum NS­Regime : Nicht nationalsozialistisch genug?

Throughout his professional life, the pathologist Albert Dietrich devoted himself to researching and combating cancer. Due to his considerable reputation and success, he was one of the first doctors to be awarded the Paracelsus Medal for his scientific services in 1952.However, Dietrich's role in the Third Reich was - and still is - far less defined. In May 1933, he became rector of the Eberhard Karls University in Tübingen, which at that time was one of the most Nazi-oriented universities. However, his term of office was short - by the end of 1933 he had already been replaced by the protestant theologian Karl Fezer.This article sheds light on Dietrich's ambivalent relationship to National Socialism and analyzes and discusses the background to his dismissal, his later (also politically influenced) emeritus status (1938/39), and his entry into the NSDAP, which took place at retirement age (1941). The study is based on archival sources partly evaluated for the first time and on a reanalysis of the relevant research literature.The study shows that Dietrich was targeted by individual Nazi decision-makers primarily because he advocated a supposedly "liberalist" university policy. Dietrich thus ultimately stands for a type of university lecturer who renounced a decidedly Nazi stance in public without, however, placing himself in a critical relationship to Nazi ideology. Against this background, statements from the postwar period that saw him retrospectively near Nazi opposition are to be classified as the formation of legends.

[Motor Skills of Extremely Obese Children and Adolescents Based on the Multicentre Longitudinal Obesity Database (APV)]. / Motorische Fitness extrem adipöser Kinder und Jugendlicher basierend auf der multizentrischen Adipositas-Patienten-Verlaufsdokumentation (APV).

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.

[Current Guidelines to Prevent Obesity in Childhood and Adolescence]. / Aktuelle Empfehlungen zur Prävention der Adipositas im Kindes- und Jugendalter.

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.

Impact of regular physical activity on blood glucose control and cardiovascular risk factors in adolescents with type 2 diabetes mellitus--a multicenter study of 578 patients from 225 centres.

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.

Work instability in rheumatoid arthritis patients from Argentina: prevalence and associated factors.

To determine the prevalence of and associated factors to work instability (WI) in rheumatoid arthritis (RA) Argentinean patients. Observational cross-sectional study that assessing employment status in currently working RA patients. They answered the validated version of RA work instability scale (RA-WIS). High-risk WI was considered when RA-WIS was ≥17. Factors associated with high-risk WI were examined by univariable and multivariable analysis. Four-hundred and fifty RA patients were enrolled; of these, 205 patients were currently employed, but only 172 have completed questionnaires required [RA-WIS and health assessment questionnaire (HAQ-A)]. Their mean age was 49.3 ± 10.8 years; 81.3 % were female; and their mean disease duration was 8.1 ± 7.2 years. Fifty-two percent of patients were doing manual work. The mean RA-WIS score was 11.4 ± 6.8, and 41 % of patients had a high-risk WI. High-risk WI was associated with radiographic erosions (p < 0.001) and HAQ-A >0.87 (p < 0.001) in the univariable analysis, whereas in the multivariable logistic regression analysis the variables associated with a high-risk WI were as follows: HAQ-A >0.87 [odds ratio (OR) 12.31; 95 % CI 5.38-28.18] and the presence of radiographic erosions (OR 4.848; 95 % CI 2.22-10.5). In this model, having a higher monthly income (OR 0.301; 95 % CI 0.096-0.943) and a better functional class (OR 0.151; 95 % CI 0.036-0.632) were protective. Forty-one percent of RA working patients had high-risk WI. The predictors of high RA-WIS were HAQ-A ≥0.87 and radiographic erosions, whereas having a better functional class and have higher incomes were protective.

Effects of health promotion projects in preschools on body mass index and motor abilities.

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.

Ultraviolet radiation and nanoparticle induced intracellular free radicals generation measured in human keratinocytes by electron paramagnetic resonance spectroscopy.

BACKGROUND: Several nanoparticle-based formulations used in cosmetics and dermatology are exposed to sunlight once applied to the skin. Therefore, it is important to study possible synergistic effects of nanoparticles and ultraviolet radiation. METHODS: Electron paramagnetic resonance spectroscopy (EPR) was used to detect intracellular free radicals induced by ultraviolet B (UVB) radiation and amorphous silica nanoparticle and to evaluate the influence of nanoparticle surface chemistry on particle cytotoxicity toward HaCaT cells. Uncoated titanium dioxide nanoparticles served as positive control. In addition, particle intracellular uptake, viability, and induction of interleukin-6 were measured. RESULTS: We found that photo-activated titanium dioxide particles induced a significant amount of intracellular free radicals. On the contrary, no intracellular free radicals were generated by the investigated silica nanoparticles in the dark as well as under UVB radiation. However, under UVB exposure, the non-functionalized silica nanoparticles altered the release of IL-6. At the same concentrations, the amino-functionalized silica nanoparticles had no influence on UVB-induced IL-6 release. CONCLUSION: EPR spectroscopy is a useful technique to measure nanoparticle-induced intracellular free radicals. Non-toxic concentrations of silica particles enhanced the toxicity of UVB radiation. This synergistic effect was not mediated by particle-generated free radicals and correlated with particle surface charge and intracellular distribution.

Thoracic impedance pneumography in propofol-sedated patients undergoing percutaneous endoscopic gastrostomy (PEG) placement in gastrointestinal endoscopy: A prospective, randomized trial.

STUDY OBJECTIVE: To assess the efficacy of an ECG-based method called thoracic impedance pneumography to reduce hypoxic events in endoscopy. DESIGN: This was a single center, 1:1 randomized controlled trial. SETTING: The trial was conducted during the placement of percutaneous endoscopic gastrostomy (PEG). PATIENTS: 173 patients who underwent PEG placement were enrolled in the present trial. Indication was oncological in most patients (89%). 58% of patients were ASA class II and 42% of patients ASA class III. INTERVENTIONS: Patients were randomized in the standard monitoring group (SM) with pulse oximetry and automatic blood pressure measurement or in the intervention group with additional thoracic impedance pneumography (TIM). Sedation was performed with propofol by gastroenterologists or trained nurses. MEASUREMENTS: Hypoxic episodes defined as SpO2 < 90% for >15 s were the primary endpoint. Secondary endpoints were minimal SpO2, apnea >10s/>30s and incurred costs. MAIN RESULTS: Additional use of thoracic impedance pneumography reduced hypoxic episodes (TIM: 31% vs SM: 49%; p = 0.016; OR 0.47; NNT 5.6) and elevated minimal SpO2 per procedure (TIM: 90.0% ± 8.9; SM: 84.0% ± 17.6; p = 0.007) significantly. Apnea events >10s and > 30s were significantly more often detected in TIM (43%; 7%) compared to SM (1%; 0%; p < 0.001; p = 0.014) resulting in a time advantage of 17 s before the occurrence of hypoxic events. As a result, adjustments of oxygen flow were significantly more often necessary in SM than in TIM (p = 0.034) and assisted ventilation was less often needed in TIM (2%) compared with SM (9%; p = 0.053). Calculated costs for the additional use of thoracic impedance pneumography were 0.13$ (0.12 €/0.11 £) per procedure. CONCLUSIONS: Additional thoracic impedance pneumography reduced the quantity and extent of hypoxic events with less need of assisted ventilation. Supplemental costs per procedure were negligible. KEY WORDS: thoracic impedance pneumography, capnography, sedation, monitoring, gastrointestinal endoscopy, percutaneous endoscopic gastrostomy.

[Sport as a means to prevention, rehabilitation, and health promotion. An expert opinion]. / Sport als Mittel in Prävention, Rehabilitation und Gesundheitsförderung. Eine Expertise.

Physical activities are particularly health effective when they are structured and systematically organized, for example, with respect to a dose-response relationship or to psychosocial aspects. Which insights can be gained from scientific knowledge on the structure of physical activities? Which health-related goals can be sought with different physical activities in the field of sport? Which target groups can be reached with these kinds of sport? These questions are addressed in this article on the basis of current scientific knowledge-to promote the development of health-enhancing physical activities especially in sport federations, but also to create a communication platform between the sport and the health sector. The work of researchers in this field is focused mainly on health-enhancing physical activity, but they are also engaged in health-related scientific organizations and in sport federations.

Training alters the skeletal muscle antioxidative capacity in non-insulin-dependent type 2 diabetic men.

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.

[Prostatic tissue in a mature cystic teratoma of the ovary: report of one case]. / Tejido prostático en teratoma quístico maduro del ovario: caso clínico.

Male accessory sexual glands arising in ovarian cystic teratoma are exceedingly rare. We report a 56-year-old female subjected to an ovariohysterectomy due to a left ovarian mass. The pathological study of the surgical piece revealed a tumor composed of different mature tissue elements and well defined nodules of benign prostatic tissue.

[Comprehensive geriatric assessment in the emergency department: some usefull screening tools]. / Evaluation gériatrique aux urgences: boîte à outils pour les nuls.

Emergency department (ED) admissions of patients 75 years and older are consistently increasing. Older patients suffer from atypical symptomatology, spend more time, and are more at risk of adverse outcomes (early readmission, functional decline, institutionalization and death) than younger people. The identification of geriatric syndromes like cognitive decline can improve the management of such patients and decrease the rate of the outcomes. In ED, screening tools developed to detect these geriatric problems have to be quick, easy to use and to present a high sensibility. This article aims at reviewing the literature about the ED-validated screening tools that could be applied in practice.

Surfeit folic acid, protein, and exercise modify oncogenic inflammatory biomarkers and fecal microbiota.

Intestinal microbiota, diet, and physical activity are inextricably linked to inflammation occurring in the presence of tumor progression and declining neurocognition. This study aimed to explore how fecal microbiota, inflammatory biomarkers, and neurocognitive behavior are influenced by voluntary exercise and surplus dietary protein and folic acid which are common health choices. Dietary treatments provided over 8 weeks to C57BL/CJ male mice (N = 76) were: Folic Acid (FA) Protein (P) Control (FPC, 17.9% P; 2 mgFA/kg); Folic Acid Deficient (FAD); Folic Acid Supplemented (FAS; 8 mgFA/kg); Low Protein Diet (LPD, 6% P); and High Protein Diet (HPD, 48% P). FAS mice had decreased plasma HCys (p < 0.05), therefore confirming consumption of FA. Objectives included examining influence of exercise using Voluntary Wheel Running (VWR) upon fecal microbiota, inflammatory biomarkers C - reactive protein (CRP), Vascular Endothelial Growth Factor (VEGF), Interleukin-6 (IL-6), nuclear factor kappa ß subunit (NF-κßp65), Caspase-3 (CASP3), Tumor Necrosis Factor-alpha (TNF-α), and neurocognitive behavior. CRP remained stable, while a significant exercise and dietary effect was notable with decreased VEGF (p < 0.05) and increased CASP3 (p < 0.05) for exercised HPD mice. Consumption of FAS did significantly increase (p < 0.05) muscle TNF-α and the ability to build a nest (p < 0.05) was significantly decreased for both FAD and LPD exercised mice. Rearing behavior was significantly increased (p < 0.05) in mice fed HPD. An emerging pattern with increased dietary protein intake revealed more distance explored in Open Field Testing. At week 1, both weighted and unweighted UniFrac principal coordinates analysis yielded significant clustering (permanova, p ≤ 0.05) associated with the specific diets. Consumption of a HPD diet resulted in the most distinct fecal microbiota composition. At the phylum level-comparing week 1 to week 8-we report a general increase in the Firmicutes/Bacteroidetes ratio, characterized by an outgrowth of Firmicutes by week 8 in all groups except the HPD. MaAsLin2 analysis corroborates this finding and emphasizes an apparent inversion of the microbiome composition at week 8 after HPD. Explicit modification of oncogenic inflammatory biomarkers and fecal microbiome post high FA and protein intake along with voluntary exercise contributed to current underlying evidence that this diet and exercise relationship has broader effects on human health and disease-perhaps importantly as a practical modulation of cancer progression and declining neurocognition.

Leukoencephalomalacia and laminar neuronal necrosis following smoke inhalation in a dog.

Acute respiratory and neurologic disease after smoke inhalation are well documented, but human patients may also develop delayed-onset neurologic symptoms associated with leukoencephalomalacia after exposure to smoke or carbon monoxide. In this case, a dog developed progressive neurologic signs 6 days after rescue from an apartment fire. At necropsy 9 days after smoke inhalation, leukoencephalomalacia of the central cerebral white matter was accompanied by laminar necrosis of cerebrocortical neurons. This is the first report of delayed posthypoxic leukoencephalopathy in a nonhuman animal.

[The CHILT I project (Children's Health Interventional Trial). A multicomponent intervention to prevent physical inactivity and overweight in primary schools]. / Das CHILT-I-Projekt (Children's Health InterventionaL Trial). Eine multimodale Maßnahme zur Prävention von Bewegungsmangel und Übergewicht an Grundschulen.

Child and juvenile obesity is increasing worldwide; therefore, effective preventive strategies are warranted. The stepwise project CHILT (Children's Health Interventional Trial) was initiated in 2000 and combines in its multicomponent school-based arm CHILT I health education and physical activity for primary school children to prevent physical inactivity and overweight. The effect on obesity and physical performance was studied in 12 primary schools (intervention schools, IS) compared with 5 control schools (CS). Anthropometric data were recorded. Physical performance was measured by a coordination test for children (the "Körperkoordinationstest für Kinder", KTK) and the 6-minute run. Anthropometric and motoric data of 436 children in IS (55.0% of the population) and 179 children in CS (62.8%) were available at baseline and at follow-up. No difference in the incidence of overweight was found between the IS and CS after 4 years of intervention. Remission of overweight was higher in IS (23.2% versus 19.2%), but not significant. The increase in BMI was significantly lower in IS, in which the program was regularly performed. There was an improvement in selected items of the KTK in IS. In particular, endurance performance tended to be higher at final examination. School-based preventive intervention seems to have a positive influence on physical motor skills and the remission of overweight. To optimize the effects, a consistent and quality assured implementation and the integration of the children's whole environment are warranted.

[Therapy of juvenile obesity from the sports medicine/science viewpoint]. / Therapie der juvenilen Adipositas aus sportmedizinisch/sportwissenschaftlicher Sicht.

Overweight and obesity in children and adolescents had reached its highest level worldwide. In the development of overweight and within interdisciplinary training programs, physical activity and the avoidance of sedentary habits play an important role. Not only is there an increase in energy consumption, but potential comorbidities (e.g., cardiovascular risk factors) are improved. In addition, positive psychosocial benefits occur, e.g., increasing self-esteem, personal, and social skills. During realization, possible risks (e.g., exercise-induced asthma) and barriers have to be taken into account. In terms of physical activity programs, the child's surroundings have to be integrated, and transfer into daily routine should be promoted. Therefore, in addition to athletic content, daily activities have to be trained and supported, e.g., via pedometers. At least 60, better 90 and more minutes of physical activity per day are recommended; the use of audiovisual media should be reduced to a minimum (max. 120 minutes).
