Uraemic symptoms as a result of reduced kidney function may impact on an individual's functional and nutritional status. This study aims to investigate whether providing individualised nutritional counselling can improve nutritional status and influence quality of life in pre-dialysis chronic kidney disease patients.
Fifty-three stage IV and V pre-dialysis chronic kidney disease patients underwent assessment of nutritional status (by Patient Generated Subjective Global Assessment) and quality of life (by Kidney Disease Quality of Life). Participants were assessed at baseline and following a 12-week randomised-controlled treatment, allocated to either individualised counselling with regular follow-up (n=24) or standard care treatment (generic education only (n=23)).
At baseline, nutritional status was significantly correlated with all general quality of life sub-scales. There was a statistically significant mean difference in change between groups for: symptoms of kidney disease (7.1 (0.1-14.1) p=0.047); cognitive functioning (14.6 (5.4-23.7) p=0.003); and vitality (12.0 (4.6-19.5) p=0.002) favouring intervention treatment.
Quality of life is related to nutritional status in pre-dialysis patients. Providing individualised nutritional counselling improves many components of quality of life, compared with standard nutrition care, in the stage prior to dialysis treatment.

    ABSTRACT: This paper addresses the theme of cooperative transportation by multiple mobile robots. There are some cases where robots are in overload by the influence of environment and the trajectory of a carrying object. In such cases the transportation becomes unstable. Thus, in this paper, the control system to prevent this problem is proposed. The proposed system consists of three control layers and the information on the system's load condition is transmitted among these layers. Based on this, the means for realizing stable transportation are performed. The system can be applied when there is various number and capability of robots. The validity of the proposed control method is checked by the simulation.

    ABSTRACT: Patients suffering from end-stage renal disease (ESRD) have a very reduced quality of life accompanied by a severe emotional distress (high worries-anxiety-depression). However, in Belgium, no regular psychological intervention is proposed to dialyzed patients. Our objective is to show that psychological intervention can significantly decrease the emotional distress of patients with ESRD. Eleven sessions of structured interventions are proposed to ESRD patients. Eligibility criteria are to be major, to not present confusion or/and dementia, to have been on dialysis treatment for at least 3months, to have obtained 14 or more on HAD-scale. Interventions carry on the management of anxious and depressive symptoms and of the disease itself. This constitutes three independent modules. Questionnaires are filled in by the patients at various stages to evaluate the anxiety and the depression (HADS), the worries (Penn State) and the quality of life (KDQoL-SF). Results for the 47 ESRD patients show a significant reduction of the scores of anxiety, depression and worries and a significant growth of quality of life. In parallel, a decrease in the serum calcium-phosphorus product analyzed before dialysis has been noted.

    ABSTRACT: The Revised Illness Perception Questionnaire (IPQ-R) measures illness perception according to the Common Sense Model of Self-Regulation. Illness perception relates to coping, health management, treatment outcomes and health-related quality of life. IPQ-R has been used in many contexts. However, there is yet no Swedish version evaluated for validity, reliability and usability in the context of a Swedish, adult population with Chronic Kidney Disease (CKD). To evaluate usability and psychometric properties of a Swedish translation of IPQ-R on a group of adults in different stages of CKD. Usability evaluation was carried out through cognitive interviews and psychometrics was assessed by internal consistency, test-retest, inter-correlations, correlations to health-related quality of life and coping and testing for concurrent validity. Content validity was strongly supported, but an uncertainty assessing symptoms attributed to CKD was indicated. All dimensions showed internal consistency, except the treatment control dimension. The IPQ-R showed good stability over time except the personal control dimension. Most IPQ-R dimensions distinguished illness representations between groups of different disease stages and symptom burden. The most supported IPQ-R dimensions for inter-correlations and convergent validity were identity, timeline cyclical, consequences and emotional representations. The evaluation of the Swedish version of IPQ-R on patients with CKD showed support for construct validity, except for the dimensions controllability, illness coherence and timeline, which were less supported. These dimensions should therefore be interpreted with care in CKD patients. There is a need to capture uncertainty regarding illness identity. IPQ-R should be interpreted with care in earlier stages of CKD or if few symptoms are reported. IPQ-R may be applicable and useful as a tool in nursing practice to support healthy behaviour as well as assessing clinical interventions in patients with CKD.
