Introductory to the ESPEN Guidelines on Enteral Nutrition: Terminology, definitions and general topics.

The ESPEN guidelines on enteral nutrition are the first evidence-based European recommendations for enteral nutrition. They were established by European experts for a variety of disease groups. During guideline development it became evident that terms and definitions in clinical nutrition have been used inconsistently depending on medical disciplines as well as regional and personal preferences. Therefore, to increase explanatory accuracy it was necessary to unify them. In this chapter terms and definitions used throughout all guidelines are explained. Additionally answers to more general questions, which might be important in most indications are dealt with, i.e. use of fibre containing and diabetes formulae.

[What does asymptomatic stenosis mean? Topics in clinical terminology and documentation].

A generally accepted classification and documentation for cerebrovascular insufficiency are needed to eliminate controversies and misinterpretation in clinical studies on the spontaneous course of the disease and the outcome of patients receiving surgical or conservative treatment. The author proposes a clinical classification (stages I to IV) based on the affected vascular territory (A, B, C). The following findings should be included: 1. the number of diseased extracranial arteries (I to IV vessel disease), 2. the presence of ischemic brain lesions (CT, SPECT, RMI), 3. concomitant diseases or risk factors (hypertension, coronary heart disease etc.). Such morphological and functional staging makes possible the selection of comparable groups of patients for investigation.

A new definition of cities.

The authors introduce a new map of Britain, which is based on the city region concept and designed specifically to present data from the 1981 census. The primary purposes of this article are "to describe the main problems and distortions which result from using current administrative areas, outline the key features of the new way of defining British cities, and demonstrate the value of the new geographical framework with some basic statistics on city size and population trends."

Population growth impacts of zero net international migration.

"In a country such as the United States, the contribution of net international migration to overall population change overshadows the contribution of natural increase.... Some analysts have assumed that if the same number of people leave and enter the country each year, then the effect of net international migration will be zero. This article examines that assumption and shows that it is fallacious. Examining the direct, indirect, total, and negative demographic impacts of zero net international migration through simulations with demographic data, we demonstrate that zero net international migration is not the same and therefore does not have the same demographic results and implications as zero international migration. We conclude that zero net international migration should not be confused with zero international migration."

[Measuring the economically active population in Mexico in the early 1990s].

"This paper refers to problems of definition and measurement of the economically active population in the early nineties in different Mexican sources of information, considering in particular the 1990 Population Census and the 1991 National Survey on Employment. The study analyzes in detail the questions, reference periods, and coding systems of these two and other previous surveys and censuses. Its findings allow us to state that the 1990 Population Census is an adequate source of information for analyzing [the] national full-time salaried work force." (SUMMARY IN ENG)

Further thoughts on simplicity and complexity in population projection models.

"This article is a review of--and response to--a special issue of Mathematical Population Studies that focused on the relative performance of simpler vs. more complex population projection models. I do not attempt to summarize or comment on each of the articles in the special issue, but rather present an additional perspective on several points: definitions of simplicity and complexity, empirical evidence regarding population forecast accuracy, the costs and benefits of disaggregation, the potential benefits of combining forecasts, criteria for evaluating projection models, and issues of economic efficiency in the production of population projections."

The validity of Australian ancestry statistics.

"This article examines the contrast between objective and subjective perceptions of ancestry hidden in the 1986 [Australian] Census definitions which vitiates the published results and points to the limitations of validating uncertain collections by relating them to cognate series. It looks at the collection of ancestry statistics as a bold attempt at an impossible task which has yielded results that are often inaccurate, sometimes misleading and liable to abuse in their interpretation. It is suggested that some of the features of cultural structure could be more reliably ascertained by small sample surveys of perceptions and aspirations."

All about U.S. immigration statistics.

The quality of data collected by the U.S. Immigration and Naturalization Service (INS) is assessed, with a focus on differences between U.S. and U.N. definitions of immigrants, emigrants, and refugees. The author suggests that "gaps in migration data collected for the U.S. limit their usefulness for studying international migration and estimating national population change. For example, no information is collected on emigration of legal permanent residents or U.S. citizens, nor is there any direct information on the immigration of U.S. citizens. Data collected on legal immigrants are based on a legal and administrative definition that often conflicts with the demographic definition of an immigrant."

The choice of diagnostic criteria for biological research.

The need for operational definitions of psychiatric syndromes is now widely accepted, and their use has improved reliability considerably. However, the existence of numerous competing definitions of several of the major syndromes and political pressures to use particular definitions highlight our lack of adequate criteria of validity. One reason why it is difficult to decide where the boundaries of individual syndromes should best be drawn is that we have largely failed to demonstrate discontinuities or "points of rarity" between related syndromes. The considerations that ought to govern the choice between competing definitions in this situation are discussed, and it is suggested that the best research strategy at present may be to use two or three alternative definitions simultaneously.
