Oncological Applications of Positron Emission Tomography with Fluorine-18 Fluorodeoxyglucose
Positron emission tomography (PET) is now primarily used in oncological indication owing to the successful application of fluorine-18 fluorodeoxyglucose (FDG) in an increasing number of clinical indications at different stages of diagnosis, and for staging and follow-up. This review first considers the biological characteristics of FDG and then discusses methodological considerations regarding its use. Clinical indications are considered, and the results achieved in respect of various organs and tumour types are reviewed in depth. The review concludes with a brief consideration of the ways in which clinical PET might be improved
A cluster-analytic approach towards multidimensional health-related behaviors in adolescents: the MoMo-Study
<p>Abstract</p> <p>Background</p> <p>Although knowledge on single health-related behaviors and their association with health parameters is available, research on multiple health-related behaviors is needed to understand the interactions among these behaviors. The aims of the study were (a) to identify typical health-related behavior patterns in German adolescents focusing on physical activity, media use and dietary behavior; (b) to describe the socio-demographic correlates of the identified clusters and (c) to study their association with overweight.</p> <p>Methods</p> <p>Within the framework of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) and the âMotorik-Modulâ (MoMo), 1,643 German adolescents (11â17 years) completed a questionnaire assessing the amount and type of weekly physical activity in sports clubs and during leisure time, weekly use of television, computer and console games and the frequency and amount of food consumption. From this data the three indices âphysical activityâ, âmedia useâ and âhealthy nutritionâ were derived and included in a cluster analysis conducted with Wardâs Method and K-means analysis. Chi-square tests were performed to identify socio-demographic correlates of the clusters as well as their association with overweight.</p> <p>Results</p> <p>Four stable clusters representing typical health-related behavior patterns were identified: Cluster 1 (16.2%)âhigh scores in physical activity index and average scores in media use index and healthy nutrition index; cluster 2 (34.6%)âhigh healthy nutrition score and below average scores in the other two indices; cluster 3 (18.4%)âlow physical activity score, low healthy nutrition score and very high media use score; cluster 4 (30.5%)âbelow average scores on all three indices. Boys were overrepresented in the clusters 1 and 3, and the relative number of adolescents with low socio-economic status as well as overweight was significantly higher than average in cluster 3.</p> <p>Conclusions</p> <p>Meaningful and stable clusters of health-related behavior were identified. These results confirm findings of another youth study hence supporting the assumption that these clusters represent typical behavior patterns of adolescents. These results are particularly relevant for the characterization of target groups for primary prevention of lifestyle diseases.</p
