Die Max-Planck-Gesellschaft als wissenschaftspolitische Akteurin in der Allianz der Wissenschaftsorganisationen
Die Allianz der Wissenschaftsorganisationen versammelt die maßgeblichen Wissenschafts- und Forschungseinrichtungen Deutschlands. Gemeinsam nimmt sie Stellung zu zentralen Fragen der Wissenschaftsorganisation, der Forschungsförderung und der strukturellen Weiterentwicklung des Wissenschaftssystems. Als intermediärer Akteur selbstverwalteter Forschung versucht sie, die divergierenden Interessen der in ihr versammelten Wissenschaftsorganisationen zu bündeln und zu harmonisieren. Der vorliegende Beitrag untersucht, wie sich die Allianz seit den 1960er Jahren herausbildete und im Wandel bundesdeutscher Forschungspolitik institutionell verfestigte. Analysiert wird, wie die einzelnen Mitgliedseinrichtungen ihre je spezifischen Interessen teils kooperativ, teils konkurrierend in diesen Formierungsprozess einbrachten und wie die Allianz auf tiefgreifende Veränderungen – sowohl hinsichtlich ihrer eigenen Zusammensetzung als auch im Hinblick auf das gesamte deutsche Wissenschaftssystem – reagierte. Die Allianz wird dabei als institutionelle Antwort verstanden, welche die Wissenschaftsorganisationen fanden, um die Interaktion von Kooperation und Konkurrenz in der Wissenschaft zu regeln. Denn trotz einer grundsätzlich bestehenden Konkurrenz um die begrenzten finanziellen Ressourcen von Bund und Ländern und unterschiedlich gelagerter Einzelinteressen etablierte sich seit den 1960er Jahren ein Muster kooperative Interessensabstimmung sowohl innerhalb der Mitgliedsorganisationen der Allianz als auch im Dialog mit dem Bundesforschungsministerium. Die Allianz konnte dabei an tiefwurzelnde Traditionen des deutschen Modells korporatistischer Politikgestaltung anknüpfen und im Bereich der Forschungspolitik verankern. Die Untersuchung der Herausbildung und Entwicklung der Allianz ermöglicht es zugleich, den Ort und die Position der Max-Planck-Gesellschaft im deutschen Wissenschaftssystem zu bestimmen. Deutlich wird, dass die MPG stets darum bemüht war, ihre Führungsrolle in der Wissenschaft offensiv wahrzunehmen und diese mit dem Anspruch an die Politik auf eine privilegierte Ressourcenausstattung verband

Psychosocial, behavioral and clinical correlates of children with overweight and obesity
Background
Psychological and behavioral correlates are considered important in the development and persistence of obesity in both adults and youth. This study aimed to identify such features in youth with severe obesity (BMI ≥ 120% of 95thpercentile of sex-specific BMI-for-age) compared to those with overweight or non-severe obesity.
Methods
Youth with BMI ≥ 85th percentile were invited to participate in a prospective research registry where data was collected on attributes such as family characteristics, eating behaviors, dietary intake, physical activity, perception of health and mental well-being, and cardiometabolic parameters.
Results
In a racially/ethnically diverse cohort of 105 youth (65% female, median age 16.1 years, range 4.62–25.5), 51% had severe obesity. The body fat percent increased with the higher levels of obesity. There were no differences in the self-reported frequency of intake of sugar sweetened beverages or fresh produce across the weight categories. However, the participants with severe obesity reported higher levels of emotional eating and eating when bored (p = 0.022), levels of stress (p = 0.013), engaged in fewer sports or organized activities (p = 0.044), and had suboptimal perception of health (p = 0.053). Asthma, depression and obstructive sleep apnea were more frequently reported in youth with severe obesity. The presence of abnormal HDL-C, HOMA-IR, hs-CRP and multiple cardiometabolic risk factors were more common among youth with severe obesity.
Conclusions
Youth with severe obesity have identifiable differences in psychosocial and behavioral attributes that can be used to develop targeted intervention strategies to improve their health
Alfalfa and flax sprouts supplementation enriches the content of bioactive compounds and lowers the cholesterol in hen egg
Abstract The effect of dietary supplementation with flax and alfalfa sprouts (40 g/d) on bioactive compounds and cholesterol contents of hen's egg was examined. Thirty White Leghorn hens, 26 weeks of age, were fed, for 66 days, three diets that included control (standard diet – C), standard diet + alfalfa sprouts (A), and standard diet + flax sprouts (F). Productive performance of hens was recorded daily. The cholesterol content of plasma and yolk, and the presence of bioactive compounds in the egg, were also analysed. Supplementation of flax and alfalfa sprouts reduced plasma and egg cholesterol probably due to the synergy between different compounds of the sprouts (polyunsaturated fatty acids - PUFAs, lignans, isoflavones and sterols). Eggs from A and F groups also had higher contents of n-3 PUFA, vitamins (α-tocopherol, α-, γ-tocotrienol, retinol), carotenes (β-carotene, lutein, zeaxanthin) and phytoestrogens (daidzein, equol, isolariciresinol) than eggs from the C group
Nutraceutical therapies for atherosclerosis
Atherosclerosis is a chronic inflammatory disease affecting large and medium arteries and is considered to be a major underlying cause of cardiovascular disease (CVD). Although the development of pharmacotherapies to treat CVD has contributed to a decline in cardiac mortality in the past few decades, CVD is estimated to be the cause of one-third of deaths globally. Nutraceuticals are natural nutritional compounds that are beneficial for the prevention or treatment of disease and, therefore, are a possible therapeutic avenue for the treatment of atherosclerosis. The purpose of this Review is to highlight potential nutraceuticals for use as antiatherogenic therapies with evidence from in vitro and in vivo studies. Furthermore, the current evidence from observational and randomized clinical studies into the role of nutraceuticals in preventing atherosclerosis in humans will also be discussed
Effectiveness of school food environment policies on children's dietary behaviors: A systematic review and meta-analysis.
BACKGROUND: School food environment policies may be a critical tool to promote healthy diets in children, yet their effectiveness remains unclear. OBJECTIVE: To systematically review and quantify the impact of school food environment policies on dietary habits, adiposity, and metabolic risk in children. METHODS: We systematically searched online databases for randomized or quasi-experimental interventions assessing effects of school food environment policies on children's dietary habits, adiposity, or metabolic risk factors. Data were extracted independently and in duplicate, and pooled using inverse-variance random-effects meta-analysis. Habitual (within+outside school) dietary intakes were the primary outcome. Heterogeneity was explored using meta-regression and subgroup analysis. Funnel plots, Begg's and Egger's test evaluated potential publication bias. RESULTS: From 6,636 abstracts, 91 interventions (55 in US/Canada, 36 in Europe/New Zealand) were included, on direct provision of healthful foods/beverages (N = 39 studies), competitive food/beverage standards (N = 29), and school meal standards (N = 39) (some interventions assessed multiple policies). Direct provision policies, which largely targeted fruits and vegetables, increased consumption of fruits by 0.27 servings/d (n = 15 estimates (95%CI: 0.17, 0.36)) and combined fruits and vegetables by 0.28 servings/d (n = 16 (0.17, 0.40)); with a slight impact on vegetables (n = 11; 0.04 (0.01, 0.08)), and no effects on total calories (n = 6; -56 kcal/d (-174, 62)). In interventions targeting water, habitual intake was unchanged (n = 3; 0.33 glasses/d (-0.27, 0.93)). Competitive food/beverage standards reduced sugar-sweetened beverage intake by 0.18 servings/d (n = 3 (-0.31, -0.05)); and unhealthy snacks by 0.17 servings/d (n = 2 (-0.22, -0.13)), without effects on total calories (n = 5; -79 kcal/d (-179, 21)). School meal standards (mainly lunch) increased fruit intake (n = 2; 0.76 servings/d (0.37, 1.16)) and reduced total fat (-1.49%energy; n = 6 (-2.42, -0.57)), saturated fat (n = 4; -0.93%energy (-1.15, -0.70)) and sodium (n = 4; -170 mg/d (-242, -98)); but not total calories (n = 8; -38 kcal/d (-137, 62)). In 17 studies evaluating adiposity, significant decreases were generally not identified; few studies assessed metabolic factors (blood lipids/glucose/pressure), with mixed findings. Significant sources of heterogeneity or publication bias were not identified. CONCLUSIONS: Specific school food environment policies can improve targeted dietary behaviors; effects on adiposity and metabolic risk require further investigation. These findings inform ongoing policy discussions and debates on best practices to improve childhood dietary habits and health
Prehospital delay in individuals with acute coronary disease: concordance of medical records and follow-up phone interviews
Patient-associated delay in seeking medical care in persons with acute coronary disease is receiving increasing importance given the time-dependent benefits associated with myocardial reperfusion therapies. We examined the extent of concordance between self-reported information about prehospital delay provided by patients to hospital staff at the time of hospitalization for coronary disease compared with information obtained from a telephone interview approximately 2 months following hospital discharge. The sample included 316 patients with acute myocardial infarction or unstable angina at 43 hospitals who had delay time information available from both data sources. The extent of agreement between the medical record and telephone accounts of delay was 47% in the total study sample, 53% in patients with acute myocardial infarction, and 40% in patients with unstable angina. These results suggest that a telephone interview carried out several months following hospitalization for acute coronary disease may not provide sufficiently reliable information about prehospital delay
