The relationship between socioeconomic status and beverage consumption in children: The Cuenca Study.

Introduction: beverage consumption constitutes a source of children's daily energy intake. Some authors have suggested that consumption of caloric beverages is higher in children with a low socioeconomic position because families limit their spending on healthy food in order to save money.

Objective: the aim of this study was to explore the relationship between socioeconomic status and Spanish children's beverage consumption.

Fiber Patterns in Young Adults Living in Different Environments (USA, Spain, and Tunisia). Anthropometric and Lifestyle Characteristics.

Benefits of dietary fiber go beyond its effect on chronic diseases associated with development. Consequently, the pattern of fiber intake has been considered an indicator for diet quality. Young adults are especially vulnerable to a food environment that drives an increase in chronic diseases linked to economic development.

Two hundred eighty-four enrolled students during the academic year 2012-2013 participated in this survey. For each individual a questionnaire involving anthropometric measurements, types of housing, smoking habits and levels of physical activity were self-reported.

Malnutrition in an elderly population without cognitive impairment living in nursing homes in Spain: study of prevalence using the Mini Nutritional Assessment test.

Background: The prevalence of malnutrition in institutionalized elderly people is generally high. A good nutritional status is related to a decrease in mortality and costs of morbidity treatments. Therefore, it is essential to know the nutritional status in order to establish action policies.

[Food habits and nutritional assessment in a university population].

Introduction: The university students are in critical period for the development of life styles which are very important for their future health. The eating behaviour of other students, the alcohol consumption, their economic situation and the ability of cooking make them change their dietary habits. In Spain there are a few studies on the quality of the diet in this population group.

Objective: To contribute to the validation of the revised BMI-MNA-SF and CC- MNA-SF with regard to association and agreement with the full-MNA, considered as gold standard, in nursing homes in Spain.

Design: Prospective analysis.

Setting: Nursing homes.

Computerized evaluation of mean residence times in multicompartmental linear system and pharmacokinetics.

Deriving mean residence times (MRTs) is an important task both in pharmacokinetics and in multicompartmental linear systems. Taking as starting point the analysis of MRTs in open or closed (Garcia-Meseguer et al., Bull Math Biol 2003, 65, 279) multicompartmental linear systems, we implement a versatile software, using the Visual Basic 6.

Mean lifetime and first-passage time of the enzyme species involved in an enzyme reaction. Application to unstable enzyme systems.

Taking as starting point the complete analysis of mean residence times in linear compartmental systems performed by Garcia-Meseguer et al. (Bull. Math.

Kinetic behaviour of proenzymes activation in the presence of different inhibitors for both activating and activated enzymes.

In the present paper, a kinetic analysis of a general model for proenzyme activation, where the activating enzyme and also the activated one are reversibly inhibited in two steps by two different inhibitors, has been performed. The cases in which both inhibitors are the same, or in which the inhibition is irreversible (only one or the two inhibition routes) are treated as particular cases of the general model. In addition, the kinetic behaviour of many other proenzyme activation systems involving inhibition, particular cases of the reaction scheme under study, can be obtained.

[Results of kidney transplantation in children weighing less than 11 kilograms].

Weigh and age are risk factors of graft failure. The aim of the study is to review the characteristics and the outcome of cadaver renal transplant in children weighing less than 11 Kg. From 1985 to 1999 10 cadaver renal transplant were performed in 10 children (7 boys and 3 girls).

Mean residence times in linear compartmental systems. Symbolic formulae for their direct evaluation.

A complete analysis has been performed of the mean residence times in linear compartmental systems, closed or open, with or without traps and with zero input. This analysis allows the derivation of explicit and simple general symbolic formulae to obtain the mean residence time in any compartment of any linear compartmental system, closed or open, with or without traps, as well as formulae to evaluate the mean residence time in the entire system like the above situations. The formulae are given as functions of the fractional transfer coefficients between the compartments and, in the case of open systems, they also include the excretion coefficients to the environment from the different compartments.

Time course equations of the amount of substance in a linear compartmental system and their computerized derivation.

In this contribution, we present the symbolic time course equations corresponding to a general model of a linear compartmental system, closed or open, with or without traps and with zero input. The steady state equations are obtained easily from the transient phase equations by setting the time --> infinity. Special attention has been given to the open systems, for which an exhaustive kinetic analysis has been developed to obtain important properties.

[value of bone densitometry in pediatric renal transplantation].

Objective: Renal transplantation improves many bone abnormalities inherent to chronic renal insufficiency, but also introduces new deleterious factors, especially those related to immunosuppressive drugs. We have studied the bone mineral content of 40 pediatric renal transplant recipients; moreover, we have analyzed its possible relationships with phosphorous-calcium metabolism, graft function and duration, steroid treatment and growth.

Patients And Methods: Bone mineral content was measured by dual energy X-ray absorptiometry (DEXA).

General linear compartment model with zero input: III. First passage residence time of enzyme systems.

In this paper, we present an alternative procedure to derive the residence times of enzyme and compartment systems. This procedure allows to express the residence time by a general, symbolic and simplified formula relating it directly with the rate constants. It is applicable to any enzyme reaction scheme which can be formulated as a set of first-order or pseudo-first order interconversions, without any other restriction.

General linear compartment model with zero input: II. The computerized derivation of the kinetic equations.

The final equations obtained in the first article of this series describing the concentrations of substances in any of the compartments of a model are here cast in an easily programmable form. A computer program with an easy input method and the ability to expand all of the coefficients in the kinetic equations in terms of the model parameters has been developed. The program has been written in the BASIC language.

General linear compartment model with zero input: I. Kinetic equations.

The derivation of kinetic equations is described for n-compartment linear models, in which the substance may be simultaneously introduced into one or more compartments at t = 0 and eliminated from any compartment. For a given zero-input, general formulas are derived which describe the amount of tracer in any of the compartments as a function of time and the model parameters. New algorithms have been developed which allow the expression of the kinetic equations.
