RESUMO
Increased international collaboration in clinical trials has created a need for cross-culturally valid instruments to assess quality of life and behavioral disorders. Cross-cultural studies of depressive symptomatology, in particular, must be preceded by an exhaustive study of the psychometric properties of the instruments, to ensure the validity of the comparison. In this article, we examine the validity, reliability and factor structure of the Spanish version of the Beck Depression Inventory (BDI) in a random stratified sample of 608 community residents in Argentina. Our findings indicate that this version of the BDI is psychometrically strong and appropriate for use in Argentina, and we suggest that it is suitable for assessing depressive symptomatology in Spanish speakers.

The relationship between liver fat content and haematology was investigated in 369 cows from eight herds sampled in the second week after calving. High levels of fat in the liver were associated with a depression in total white cell count and in neutrophils, eosinophils and lymphocytes. There was no correlation between liver fat content and the percentage of E rosetting lymphocytes, packed cell volume or haemoglobin concentration. The changes in peripheral white cell counts may be related to the increased incidence of post parturient disease in cows with fatty liver.

An enzymatic method for the measurement of non-esterified fatty acid (NEFA) concentrations in blood was applied to samples from dairy cows. The method was carried out on a discrete analyser and showed considerable savings over other methods, particularly in time. The precision of the method was very high and the accuracy was good within normal concentration ranges when compared with an extraction reference method. Using this enzymatic method, it is possible to measure NEFA concentrations in bovine serum or plasma on a routine basis. The results will be of particular value in assessing the metabolic and nutritional status of cows in the post parturient period.

Cows from three different herds were used to investigate the relationship between plasma D(-)-3-hydroxybutyrate, serum free fatty acid and blood glucose concentrations and the amount of fat present in the liver in the week after calving. The study was particularly concerned with the diagnostic value of D(-)-3-hydroxybutyrate estimations. These estimations did not make a significant contribution to diagnosis of fatty liver nor did they reflect accurately the nutritional status of the cows.
