Aim: Different providers of obesity treatment in children and adolescents in Germany were compared using the following criteria: outpatient/inpatient; with/without AGA certification; good/less good quality. Methods: A total of 1,916 patients (8-16.9 years) from 48 study centers were examined before (t0), after (t1), and at least 1 year after therapy (t2/3). Body mass index (BMI), blood pressure, blood lipids, and psychosocial data were measured. Results: Patients from inpatient rehabilitation centers were older and more obese. Patients from AGA-certified centers were more obese, and the completeness of comorbidity screening was higher. There were no differences in short- or long-term BMI reduction. "Good" treatment centers (classified after the UKE study 2004) did not differ from those centers not rated as "good" in weight reduction. Patients treated in "good" centers were more obese, and screening for comorbidity was better. No differences in drop out and loss to follow-up were found. Conclusion: There were only small differences between the different groups. Pronounced differences were found between the individual treatment centers. In order to improve therapy processes and outcomes, benchmarking and quality management have to be extended. © 2011 Springer Medizin Verlag. Source

Inflammatory processes play a central role in the development of atherosclerosis. Various families of lipid mediators derived from long-chain omega-3 fatty acids eicosapentaenoic acid (EPA) and docosapentae-noic acid (DHA) were recently identified to function as pro-resolving mediators. These locally acting mediators include resolvins, protectins and marensins. They act via specific receptors activating pro-resolving programmes on several target cells. Because the progression of chronic inflammatory diseases could be connected with impaired resolution processes, pro-resolving lipid mediators, generated from EPA and DHA, may have beneficial roles in prevention of atherosclerosis. One of the possibilities of facilitating the biosynthesis of omega-3 fatty acid derived from pro-resolving lipid mediators is by supplementation with EPA and DHA. Therefore, intake of long-chain fatty acids is important for health both on population basis and in subjects with increased cardiovascular risk. © Verlag PERFUSION GmbH. Source

If sport is performed regularly, it is necessary to put a focus on dietary behaviour in order to maintain health and performance. The following points are particularly important. For optimal energy requirements in sports, at least 50 % of energy should be provided by carbohydrates. For endurance sport, 60-65 % carbohydrate may be needed. Particularly for endurance sport lasting more than an hour, carbohydrate intake during the competition is desirable. To optimise glycogen resynthesis, carbohydrates of intermediate to high glycaemic index should be taken immediately after the end of the exercise, for up to 4 hours. Fat intake should not be more than 35 % of the total calorie intake; fat is not a limiting factor for physical performance. For sports involving strength or endurance type of exercise, the recommended protein intake of 1.2-1.7 g/kg body weight/day provides enough protein for regeneration and reforming muscle. If endurance sport lasts for at least one hour, fluid should be taken every 15-20 min. 0.8 I fluid per hour is accepted in endurance sport. The drink should be weakly hypotonic to isotonic. Supplementation with high doses of antioxidative vitamins does not improve muscular performance. It can be assumed that balanced and fully adequate nutrition guarantees the intake of vitamin levels which are needed for optimisation of plasma concentrations. Source

The aim was to investigate the feasibility to perform cardiac magnetic resonance imaging (MRI) using a MR compatible Doppler-ultrasound (US) device as a new method to trigger the human heart cycle. MRI images were compared between ECG and Dopplerultrasound triggered examination in terms of image quality by an objective measure of acutance and functional assessment. © 2013 by Walter de Gruyter.

Background. In case of a mass casualty event, emergency services bear the primary responsibility for decontaminating patients. Over the course of many emergencies, we have learned that not all patients stay at the site of a disaster. They try to reach the nearest known medical facility by themselves or with the help of others. Even in CBRN (chemical, biological, radiological, and nuclear) situations they might not wait for the arrival of the rescue services. All hospitals must, therefore, be prepared for such events. They must have facilities for decontaminating and treating patients after such events in order to protect their staff and the hospital itself. This article describes the equipment needed, knowledge necessary, and steps to be taken, considering cost pressures and decreases in personnel in German hospitals. Every hospital should be able to admit patients in the wake of a CBRN incident. The questions that need answering are the following: What kind of preparation is most expedient? Materials and methods. At an emergency hospital, a decontamination site was established and run using only standard hospital equipment and 9 members of the hospital staff without prior education on decontamination. Following registration with three different materials (identification wristband, hanging badge, felt-tip pen mark on the back of the hand), 25 persons were sprinkled with one invisible surrogate contaminant (fluorescine) and one visible surrogate contaminant (flour). Decontamination was performed using water, common hospital soap, and sponges. The decontamination performance was assessed using both normal light and black light. Subsequent to the exercise every staff member and every proband was asked, via questionnaire, to judge the decontamination process and its effects on personnel and probands. Results. The setup of the decontamination unit by untrained staff members revealed no problems; the unit was operative within 18 min. The decontamination of all probands took 90 min. Successful decontamination of the visible contaminant was observed on 61.5% of the probands, and of the invisible contaminant on 26.9% of the probands. The capacity of our decontamination unit determined by a standard formula was less than estimated, due to a bottleneck at the arrival facility. The strain on the staff members using NBC-protective suits was noncritical; however, the limited communication with team members and patients was criticized. Only the hanging badges for registration were suitable for sufficient decontamination and safe identification. Conclusions. No special knowledge is necessary to develop a predesigned hospital decontamination unit using normal hospital materials and gear and untrained personnel. Nine people are sufficient to run the unit. They need some special education to perform adequate decontamination. Improved communication technology is required. Prior to calculating a given hospital's capacity for treating the victims of contamination, an evaluation of the decontamination process and its specific limitations at that hospital is required. Only the hanging badges for registration allowed sufficient decontamination and safe identification. © Springer-Verlag 2013. Source
