- Objective. To evaluate whether percent Gleason grade 4/5 (i.e. the proportion of a tumor occupied by high-grade cancer) can be predicted by multiple needle biopsies. Material and methods. In 115 men, 8-14 (mean 10) biopsies were taken, including eight from standardized positions (apex, mid-medial, mid-lateral and base). Biopsies were reviewed and cancer lengths measured. All men underwent radical prostatectomy. The prostatectomy specimens were totally embedded and tumor volume measured planimetrically. Gleason scores and percent Gleason grade 4/5 were assessed for both biopsy and prostatectomy specimens. Results. Percent Gleason grade 4/5 in prostatectomy specimens was predicted correctly in 34% of cases and within 10%, 20% and 30% in 55%, 64% and 73% of cases, respectively. Biopsies had a sensitivity, specificity and accuracy for Gleason grade 4/5 of 62%, 87% and 69%, respectively. Positive and negative predictive values were 93% and 45%, respectively. The weighted kappa value for agreement was slightly higher for Gleason score (0.685) than for percent Gleason grade 4/5 (0.573). The univariate correlation for percent Gleason grade 4/5 in biopsies and the main tumor was r = 0.62, r(2) = 0.39 (p < 0.001). In univariate logistic regression, percent Gleason grade 4/5 on biopsies predicted the presence of any Gleason grade 4/5 cancer in the main tumor (p = 0.009). Conclusions. Gleason grade 4/5 in prostatectomy specimens correlates with findings in preoperative biopsies. Whether this measure will be used in routine practice remains to be seen.

- Aims. To follow weight changes in patients with moderate and severe dementia and analyse how these changes related to biological and psychological parameters after staff education and support in integrity promoting care. A further aim was to describe meal environment and routines relative to the intervention.Background. Weight loss in patients with dementia and in particular Alzheimer's disease is common. The aetiology appears multifactorial with the meal environment and a decreased independence while eating among the factors.Method. Over a three-month intervention period, an integrity-promoting care training programme was conducted with the staff of a long-term ward. Alzheimer's disease patients, 18 from an intervention ward and 15 from a control ward were included and possible effects were evaluated. Weighing was conducted at the start and after completion of the intervention. Weight changes were analysed in relation to psychological and biochemical parameters. In addition, the staff wrote diaries about, for example changes made in the environment and in their work.Results. The most prominent difference observed was weight increases in 13 of 18 patients compared with two of 15 patients in the control ward. No weight changes were related to the type of dementia. The individual weight changes correlated significantly to changes in the intellectual functions. Relationships between weight change, increased motor function and increased appetite were non-significant. There was no significant relationship between weight changes and changes in biochemical parameters. According to the staff, increased contact with the patients and a more pleasant atmosphere resulted when the meal environment and routines were changed.Relevance to clinical practice. Weight gain in patients with moderate and severe dementia was achieved by adjusting the meal environment to the individual's needs. Staff education was profitable, as increased competence seemed to promote individually adapted feeding situations. Ensuring good meal situations need to be given high priority.
