Functional dyspepsia is a common disorder in primary care and gastroenterology units; however, the pathophysiology is poorly understood. Delayed gastric emptying is present in nearly 40% of patients. We evaluated the validity of the paracetamol absorption test in comparison with scintigraphy for gastric emptying assessment. Studies comparing scintigraphy with paracetamol absorption were selected through a structured Medline search. A correlation coefficient between scintigraphy and paracetamol absorption over 0.6 was considered good, between 0.45 and 0.6 intermediate, and below 0.45 poor. Feasibility was assessed by studying the administration of paracetamol, frequency of blood sampling, duration of the test period, and parameters used in the analysis. Thirteen studies were identified, eight (127 subjects) found a good correlation between scintigraphy and paracetamol absorption, two studies (28 subjects) found a moderate correlation, and three (25 subjects) found no correlation. Parameters used were area under the curve (N = 9), fixed-time concentrations (N = 6), concentration-max (N = 4) and time-to-concentration-max (N = 5). Repetitive blood samples ranged from 6 to 20 samples. The durations were 1.5-8 h. In conclusion, the paracetamol absorption technique generally correlates well to scintigraphy of liquid phase gastric emptying. The execution and outcome parameters however need further standardization to optimize its' value for clinical use and research purposes.

Dealing with sexual problems due to disease or disability is part of medical rehabilitation, but both patients and professionals experience barriers to discuss sexual issues. A brief discipline-specific sexological training for rehabilitation professionals was therefore developed and evaluated in two rehabilitation centers in The Netherlands. Among the 283 participants were physicians (42), physical therapists (38), occupational therapists (40), psychologists and social workers (26), nurses (101), and other disciplines (36). Measurements before training, after training, and at 3-4 months follow-up showed increase of self-rated sexological competence and of scores on the Knowledge, Comfort, Approach, and Attitudes towards Sexuality Scale (KCAASS) during the training that were maintained at follow-up. Disciplines differed in sexual competence before training and in increase of sexual competence after training. Implementation of the training in other rehabilitation centers is recommended.

Based on patient's reports of HP behaviour, the KB-intervention appears effective since more patients felt encouraged to be physically active after the intervention compared to before. Replication of this study in an experimental design is needed to allow causal inferences. Implications for rehabilitation We advise rehabilitation teams to make use of knowledge brokers (KBs), since the KB-intervention was shown to increase the encouragement felt by stroke patients to be physically active. It seems worthwhile to involve physicians, nurses and patients' families more frequently in efforts to encourage stroke patients to be physically active.

The quality specifications for partly and fully processed oils sold to the European Edible Fats industry are discussed. The industry generally has regarded quality specifications as giving some guarantee of parameters such as FFA, moisture, impurities, iodine value and solids content. However, the availability of processed oils leads us to consider other aspects of quality apart from those normally required. In particular, potential hazards associated with refining and transport procedures become increasingly significant if the European industry is to consider using fully refined oils directly in products. As long as suppliers are unable to make the necessary guarantees, Unilever companies in Europe will be unable to take full advantage of the potential benefits offered by the palm oil industry. The above topics, together with a description of the specification required for the specific product applications, are discussed in this paper.
