In a diary-survey study in 234 households with children aged 4-12 years, we investigated the associations between children's exposure to food advertising and their consumption of (a) advertised food brands, (b) advertised energy-dense food product categories, and (c) food products overall. Relations were examined using multiple hierarchical regression analysis, while controlling for various child (i.e., age, sex, television viewing time) and family variables (i.e., family income and consumption-related communication styles). Results showed that children's exposure to food advertising was significantly related to their consumption of advertised brands (beta=.21) and energy-dense product categories (beta=.19). The relation between advertising exposure and overall food consumption only held in lower-income families (beta=.19). In addition, consumption-related family communication was an important moderator of the relations between advertising and the food consumption variables. Socio-oriented family communication (i.e., striving for harmony and conformity) was particularly successful in reducing these relations. In conclusion, consistent with communication theories predicting spill-over effects of advertising, the impact of television food advertising exceeded the advertised brand and generalized to more generic unhealthy consumption patterns. Theoretical and societal consequences, as well as the important role of the family are discussed. 相似文献

Summary The configuration of the constant properitoneal body of fat with contained vasculature (ensiform vessels and portions of the ligamentum teres) and its relationship to the falciform ligament were studied by reviewing 122 computer tomographic scans of 103 patients with ascites. The maximal width was found in 57% at the level of the intrahepatic ligamentum teres immediately after entry into the liver but maximal thickness was mostly found higher up. Our measurements of mean maximal width and thickness of 7.2 cm and 1.2 cm respectively, corresponded well with disssection findings in the literature. A variety of pathologic conditions can affect the fat pad via connecting or adjacent structures like the falciform ligament, lesser omentum, properitoneal flank fat, mediastinal fat or transperitoneally. However, involvement by pathology was infrequent.
Le bourrelet adipeux propéritonéal. Etude par imagerie de ses relations avec le ligament falciforme. Déductions cliniques
Résumé Une étude morphologique du bourrelet adipeux pro-péritonéal médian, de son contenu et de ses relations avec le ligament falciforme a été faite à partir de l'analyse de 122 examens TDM effectués chez 103 patients présentant une ascite. La largeur maximale de ce capitonnage adipeux se situe dans 57 % des cas, juste après la pénétration du ligament rond du foie dans le parenchyme hépatique et l'épaisseur maximale se situe un petit peu plus haut. Les dimensions moyennes de la largeur et de l'épaisseur maximales de ce bourrelet adipeux sont respectivement de 7,2 cm et 1,2 cm, mesure identique à celle que l'on trouve dans la littérature à partir de travaux de dissection. Un certain nombre de modifications pathologiques des structures de voisinage, telles que le ligament falciforme, le grand épiploon, la graisse extra-péritonéale des flancs, la graisse médiastinale peuvent modifier ce capitonnage; toutefois, les lésions propres au bourrelet adipeux sont rares.相似文献

Background
Animal models with various combination of host-parasite have long been employed to study malaria pathogenesis. Here, we describe the combination of Plasmodium berghei ANKA infection in inbred ICR mice as a model of cerebral malaria (CM).Methods
Infection in mice was initiated by intraperitoneal injection of 2 x 107 (0.2ml) parasitized red blood cells (PRBCs).Results
This model can produce a severe degree of infection presented by the high degree of parasitaemia followed by death 6-7 days post infection. Severe anemia, splenomegaly, hepatomegaly and discolourations of major organs were observed. Histopathological findings revealed several important features mimicking human CM including, microvascular sequestration of PRBCs in major organs, particularly in the brain, hypertrophy and hyperplasia of the kupffer cells in the liver, pulmonary edema and hyaline membrane formation in the lungs and haemorrhages in the kidney''s medulla and cortex. Proinflammatory cytokines TNFα, IFNγ, IL-1, IL-6 and IL-18, and anti-inflammatory cytokine IL-10 were all found to be elevated in the plasma of infected mice.Conclusion
This model can reproduce many of the important features of CM and therefore can be used as a tool to advance our understanding of the disease pathogenesis. 相似文献16.

Some 60% of strokes are due to extracranial occlusive arterial lesions, most frequently at the bifurcation of the common carotid artery. Since these lesions are accessible to endarterectomy, their prestroke diagnosis is very important. Facial thermography quickly supplies reliqble information on the circulatory area in which these lesions occur, and this information can be atraumatically obtained in an out-patient setting. The success rate of facial thermography versus aortic arch angiography was 83% and 80%, respectively, in our case material, and this rate corresponds with data in the literature. In a series of 23 patients with facial thermograms and angiograms obtained before and after endarterectomy, facial thermography proved to be a useful diagnostic and prognostic aid in neurological out-patient guidance after carotid endarterectomy. By virtue of its rapidity and atraumatic character, because it can be carried out by technicians and because the findings are suitable for computer data processing, facial thermography would seem to be suitable for potential stroke screening of a high-risk asymptomatic population. 相似文献

Background
Spina Bifida (SB) is the second most common birth defect worldwide. Since the chances of survival in children with severe SB-forms have increased, medical care has shifted its emphasis from life-saving interventions to fostering the quality of life for these children and their families. Little is known, however, about the impact of SB on family adjustment. Reviewers have struggled to synthesize the few contradictory studies available. In this systematic review a new attempt was made to summarize the findings by using meta-analysis and by delimiting the scope of review to one concept of family adjustment: Parents' psychological adjustment. The questions addressed were: (a) do parents of children with SB have more psychological distress than controls? (b) do mothers and fathers differ? and (c) which factors correlate with variations in psychological adjustment?Methods
PsycInfo, Medline, and reference lists were scanned. Thirty-three relevant studies were identified of which 15 were eligible for meta-analysis.Results
SB had a negative medium-large effect on parents' psychological adjustment. The effect was more heterogeneous for mothers than for fathers. In the reviewed studies child factors (age, conduct problems, emotional problems, and mental retardation), parent factors (SES, hope, appraised stress, coping, and parenting competence), family factors (family income, partner relationship, and family climate), and environmental factors (social support) were found to be associated with variations in parents' psychological adjustment.Conclusion
Meta-analysis proved to be helpful in organizing studies. Clinical implications indicate a need to be especially alert to psychological suffering in mothers of children with SB. Future research should increase sample sizes through multi-center collaborations.19.
In this paper, we provide an overview of databases that are of importance to clinical geneticists. Some suggestions for the fruitful use for both research and diagnosis are given. For beginning ‘web-surfers’ we also list some well-known search engines and give a short overview of how to use these and other services. In addition, the URLs of some of the most important databases, gateways and tutorials are listed. 相似文献
