Es wird eine empirische Untersuchung vorgestellt, bei der die Frage beantwortet werden soll, ob sich die Fitness luxemburger Schülerinnen und Schüler in den letzten zwei Jahrzehnten verschlechtert hat. Hierzu wurden sportmotorische Tests durchgeführt und mit Normwerten aus dem Jahr 1985 verglichen. Es zeigen sich hoch signifikante schlechtere Fitnesswerte der luxemburger Jungen und Mädchen. Die Fitnesswerte von rund drei Viertel der Mädchen können als schlecht bezeichnet werden. Nur die 14-jährigen Jungen erreichen die Normwerte. Die Fitness hängt dabei nicht von der Zahl der angegebenen Sportstunden pro Woche ab. Einen hoch signifikanten Einfluss hat hingegen die Zugehörigkeit zu einem Sportverein. Es zeigen sich des Weiteren Auswirkungen auf die Gesundheit. Die fitteren Kinder haben ein hoch signifikant besseres allgemeines Wohlbefinden als die weniger leistungsfähigen. [less ▲]

OBJECTIVE: It is controversial whether alteration of cerebral perfusion plays an important role in the pathophysiology of patients with idiopathic normal pressure hydrocephalus (NPH) and can help to predict the outcome after shunt surgery. MATERIALS AND METHODS: 28 patients with suspected NPH were examined clinically (Homburg Hydrocephalus Scale, walking test, incontinence protocol) and by 3D dynamic susceptibility based perfusion weighted magnetic resonance imaging (PWI-MRI) before and after cerebrospinal fluid release (spinal tap test, STT). The perfusion parameters (negative integral (NI), time of arrival (T0), time to peak (TTP), mean transit time, and the difference TTP-T0 were analysed. RESULTS: Three different groups of patients were identified preoperatively: In group 1 seven patients showed an increase in the cerebral perfusion and a clinical improvement after STT. The second group (9 patients) also revealed an increase of the cerebral perfusion, but no significant alteration of the clinical assessment could be found. In the third group neither the cerebral perfusion nor the clinical assessment changed. 14 of the 16 patients (group 1 and 2) were examined three months after shunt placement. 11 patients showed a good or excellent result, 2 patients revealed a fair assessment, and only 1 patient had transiently improved. No patient was downgraded after shunting. In the patient group 1 and 2 the NI increased significantly (effect size: 34%), whereas in group 3 no significant alteration of NI was observed. CONCLUSION: PWI-MRI improves the prediction of outcome after shunt placement in patients with NPH and can offer new insights into the pathophysiology. [less ▲]

BACKGROUND: Sleep abnormalities in Parkinson's disease (PD) are frequent, but it is unknown whether or not there is progressive loss of physiological sleep architecture or what the causes could be. METHODS: Retrospective review of medical records and polysomnographic data from 46 non-demented PD patients. RESULTS: Sleep latency was correlated with disease duration (F1,44=4.87, P=0.03). Total sleep time (F1,44=8.54, P=0.005), deep sleep time (F1,44=4.06, P=0.05), REM sleep time (F1,44=9.15, P=0.004) and sleep efficiency (SE) (F1,44=10.20, P=0.003) were inversely correlated with disease duration. The same sleep parameters were independent from the degree of motor impairment, dosage of the dopaminergic medications, and age. Subjective sleep complaints could only partially predict abnormalities in polysomnographic (PSG) studies. CONCLUSION: In PD nocturnal sleep 'destructuring' is linked to disease duration and evolves independently from other major disease parameters. [less ▲]

Fish consumption and coronary heart disease: A review of data on the dose-response relationship

Although a rich source of n-3 polyunsaturated fatty acids (PUFAs) that may confer multiple health benefits, some fish contain methyl mercury (MeHg), which may harm the developing fetus. U.S. government recommendations for women of childbearing age are to modify consumption of high-MeHg fish to reduce MeHg exposure, while recommendations encourage fishconsumption among the general population because of the nutritional benefits. The Harvard Center for Risk Analysis convened an expert panel (see acknowledgments) to quantify the net impact of resulting hypothetical changes in fishconsumption across the population. This paper estimates the impact of fishconsumption on coronaryheartdisease (CHD) mortality and nonfatal myocardial infarction (MI). Other papers quantify stroke risk and the impacts of both prenatal MeHg exposure and maternal intake of n-3 PUFAs on cognitive development. This analysis identified articles in a recent qualitative review appropriate for the development of a dose–response relationship. Studies had to satisfy quality criteria, quantify fish intake, and report the precision of the relative risk estimates. Relative risk results were averaged, weighted proportionately by precision. CHD risks associated with MeHg exposure were reviewed qualitatively because the available literature was judged inadequate for quantitative analysis. Eight studies were identified (29 exposure groups). Our analysis estimated that consuming small quantities of fish is associated with a 17% reduction in CHD mortality risk, with each additional serving per week associated with a further reduction in this risk of 3.9%. Small quantities of fishconsumption were associated with risk reductions in nonfatal MI risk by 27%, but additional fishconsumption conferred no incremental benefits. [less ▲]
