Heat stress negatively impacts a variety of dairy parameters including milk yield and reproduction and therefore is a significant financial burden (~$900 million/year in the USA; St. Pierre et al., 2003) in many dairy-producing areas of the world. Advances in management (i.e. cooling systems; Armstrong, 1994; VanBaale et al., 2005) and nutritional strategies (West, 2003) have alleviated some of...

Data from a previous study were analysed to develop a new model for neonatal nutritional evaluation which is independent of precise maturity determination. Birth weights and arm/head ratios were recorded for each infant recruited for the study. Both indices were correlated by simple regression analysis with gestational age as the independent variable. Birth weight showed highly significant corr...

The nutritional condition of turbot larvae (Scophthalmus maximus) was assessed by a multivariate analysis with DNA, RNA, and protein content as input variables. Special attention was given to the time that feeding began and to the timing and duration of starvation. The combination of the principal components analysis and the stepwise discriminant analysis, both techniques of multivariate analys...

BACKGROUND Several studies have pointed out the influence of nutritional parameters and/or indices of inflammation on morbidity and mortality. Often, these conditions coexist, and the relative importance of poor nutritional status and chronic inflammation in terms of predicting clinical outcomes in chronic hemodialysis (CHD) patients has not been clarified. METHODS We undertook a prospective ...

Malnutrition is common in the critically ill patients and known to cause a variety of negative clinical outcomes. However, various conventional methods for nutrition assessment have several limitations. We hypothesized that body composition data, as measured using bioelectrical impedance analysis (BIA), may have a significant role in evaluating nutritional status and predicting clinical outcome...

This paper compares the Portuguese and Bulgarian consumer price indices (CPI) and attempts to identify some areas in which the CPI compilation methodology could be improved in the two countries. This work is organised into six sections. The first section briefly describes the organisational structure on which the production of the CPI is based in the two countries. The second section focuses on...

OBJECTIVE To evaluate the prevalence of bone mineral disease among adolescents with cystic fibrosis and to relate the findings with the variables studied. METHODS The study enrolled 37 adolescents who were assessed for: nutritional status according to height/age and body mass/age ratios; bone mineral density of the lumbar spine and entire body by densitometry with dual emission X-ray; daily d...

OBJECTIVE To assess reliability of information about nutritional facts stated on labels of foods marketed. METHODS A total of 153 industrialized foods, usually consumed by children and adolescents and marketed in the city of São Paulo, Southeastern Brazil, between 2001 and 2005, were analyzed. Nutrient contents stated on labels were compared to the results obtained from official (physical-che...

BACKGROUND Chronic kidney disease is a common condition in the general population, particularly among older adults. Renal impairment is in turn associated with metabolic and nutritional derangements and with increased risk of cardiovascular disease. AIM To compare the metabolic, nutritional, and cardiovascular impact of reduced kidney function between patients with and without known renal dis...

Some socio-economic and demographic factors contributing to nutritional status (underweight and wasting) of children aged 1 to 4 years (n = 949) were studied in selected low income urban areas in Tanzania. Children were classified as either normal or malnourished and logistic regression was used in the analysis. Of the demographic variables studied, sex of the child was significant using both w...
