Drug use, violence, and victimization among White American, Mexican American, and American Indian dropouts, students with academic problems, and students in good academic standing.

Problem-prone behaviors of White American, Mexican American, and American Indian high school dropouts, students in good academic standing, and students in poor academic standing were surveyed. Generally, dropouts were most involved with drugs, perpetration of violence, and victimization by violence, students in poor standing were the next most involved, and students in good standing were least involved. Ethnicity did not interact with academic status, suggesting that differences between dropouts and students were similar across ethnic groups. Some ethnicity and gender main effects were found. Findings were related to R. Jessor's (see record 1992-23064-001) theory of problem-prone behaviors, to peer cluster theory, and to intervention design.

The therapeutic relationship as the foundation for treatment with adult survivors of sexual abuse.

Survivors of sexual abuse enter psychotherapy with special needs that challenge some of the traditional therapeutic assumptions. The therapeutic relationship, which is the foundation for treatment with abuse survivors, often must shift in nature and quality to address these needs. The main goal of treatment is the integration of self and affective experience. To facilitate this process the authors discuss the establishment and maintenance of an "affective edge" that allows for direct attention to and intervention with the trauma memories and the accompanying affect.

External validation of the Personality Inventory for Children: Comment on Lachar, Gdowski, and Snyder.

Comments on the D. Lachar et al (see record 1984-19420-001) evidence of external validity for Personality Inventory for Children (PIC), which is based on correlations of PIC scales with dimension scores derived from factor analyses of behavioral ratings. It is argued that due to considerable item overlap between PIC scales and behavior rating forms, correlations may be an indication of rater reliability rather than one of construct validity. This problem is thought to be especially evident for rating forms completed by parents because parents also completed the PIC, and many items are similar in both content and wording. The problem is illustrated using the hostility/dyscontrol dimension derived from parent ratings. (2 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Quality of ecologically produced foods of animal origin

The production of organic (ecological) food of animal origin is done in many ways and uses many different breeds. Therefore a real comparison with conventionally produced food is difficult. From the limited number of published data it appears, that the characteristics of quality of the products, the nutritional, hygienic, sensorial and technological factors, are not very different in both systems of production. In some factors organic food gets better marks, in others the conventionally produced food. The differences are in the production system (process quality) during lifetime of the animals.     

Sucrosemia in untreated celiac disease: a potential screening test

During studies to develop serum tests of small intestinal permeability, we detected an unidentified disaccharide in HPLC traces of sera from untreated celiacs. This present study aimed to identify the disaccharide and determine whether the presence of the disaccharide in the serum after an oral challenge had potential as a simple screening test for celiac disease. The disaccharide was identified as sucrose by incubation studies of sera with disaccharidases. Twenty untreated celiacs, 15 treated celiacs, and 20 normal or dyspeptic controls were studied for the presence of sucrose in their serum after an oral load (8 g). The results in celiacs were compared with the presence of serum IgA endomysial antibodies. The 10 normal controls were also given a larger sucrose challenge (50 g). Ten of the untreated celiacs and 10 controls had their brush border disaccharidase activities measured. Sucrose eluted in the same position as the unidentified disaccharide in the HPLC trace and the latter could be removed by incubation with sucrase. All untreated celiacs but none of the treated celiacs had sucrose in their serum after the 8-g oral challenge. None of the controls had sucrose in their serum after the 8-g or 50-g challenges. Three untreated celiacs were IgA endomysial antibody negative as were all the treated cases. Brush border sucrase activity was low in untreated celiac disease. The presence of sucrose in the serum after an oral load shows promise as a noninvasive test for celiac disease.     

Inhibition by 5-(tetradecyloxy)-2-furoic acid of fatty acid and cholesterol synthesis in isolated rat hepatocytes

Fatty acid and cholesterol synthesis in isolated rat hepatocytes were strongly inhibited by 5-(tetradecyloxy)-2-furoic acid. With either³H₂O or [2-¹⁴C]acetate as the labeled precursor, the concentrations of inhibitor causing 50% decrease in fatty acid and cholesterol synthesis were, respectively, <0.005 mM and 0.020 mM. At 0.1 mM inhibitor, citrate concentration in cells from fed rats was increased by 75%; lactate and pyruvate concentrations were decreased by 30%; ethanol oxidation was decreased by 20%; with cells from starved rats, the mitochondrial [NAD⁺]/[NADH] was decreased. Other parameters were unaffected. Both its potency and its specificity indicate that 5-(tetradecyloxy)-2-furoic acid will be useful in studies on the regulation of lipid biosynthesis.     

Development of clinical indicators for performance measurement and improvement: an HMO/purchaser collaborative effort

This article describes a collaborative effort between a major health care purchaser, three area health maintenance organizations, and a state Medicaid agency to develop clinical indicators as the basis for a comparison database. Some of the difficulties in developing a "common yardstick" of quality and value are candidly discussed.
