Using the recommended daily allowance (RDA) to assess dietary adequacy implies making a direct comparison between RDA and some measure of dietary intake. The value and usefulness of doing so must clearly depend on the limitations of each. By definition the RDA are intended to cover ‘the average amount of the nutrient, which should be provided per head in a group of people if the needs of practi...

The adult RDA is defined as the average daily level of intake sufficient to meet the nutrient requirements of nearly all healthy people. The RDA for protein for adults ≥18 y of age (0.8 g/kg) has been essentially unchanged for >70 y. In practice, the RDA for protein was derived to estimate the minimum amount of protein that must be eaten to avoid a loss of body nitrogen. The Acceptable Macronut...

OBJECTIVES To compare the dietary intakes of Dutch nutrition and dietetics students with the Dutch RDA and the Dutch National Food Consumption Survey (DNFCS), and to assess whether dietary intake changes during education. DESIGN Cross-sectional and longitudinal research (2004-2010). SETTING Data collection by 7 d dietary record and questionnaire. SUBJECTS Dutch nutrition and dietetics stu...

A new formalism of Resource Driven Automata Nets (RDA-nets) is presented. A RDA-net has two levels: a system level is represented by a net of active resources, describing distribution of agents/resources and their interactions; agents in an object level are finite automata, communicating via ports and shared resources of a system level. RDA-nets are assigned for modeling mobility in multi-agent...

Destructive communication is a problem within the NHS; however previous research has focused on bullying. Rude, dismissive and aggressive (RDA) communication between doctors is a more widespread problem and underinvestigated. We conducted a mixed method study combining a survey and focus groups to describe the extent of RDA communication between doctors, its context and subsequent impact. In to...

Forty patients with "rate dependent aberrancy" (RDA) were studied. This large group of patients permitted a clear definition of the syndromne and recognition of a number of features not previously described. These proved to have a significant bearing on the recognition and differential diagnosis of RDA and non-rate dependent aberrancy. It was found that a small change in cycle length, perhaps t...

The difference products (DP) of representational difference analyses (RDA) were used as hybridization probes on cDNA arrays. The effectivity of RDA products obtained with increasing driver/tester ratios (DP 1 = 100:1, DP 2 = 800:1 and DP 3 = 400,000:1) to isolate differentially expressed genes was compared with the effectivity of conventional differential hybridizations. Pacreatic cancer and co...

Helicobacter infection leads to chronic inflammation of the stomach. Although the infection persists in spite of an immune response, animal studies have shown that adjuvant-based oral vaccines can protect against infection and even eliminate established infection. These vaccines are thought to induce a Th2 immune response, counterbalancing the Th1 response seen with natural infections. As a pre...
