Determinants of Perceived Health Nonimprovement in Early Rheumatoid Arthritis Patients With Favorable Treatment Outcomes.

OBJECTIVE: To explore the association between achieving favorable clinical outcomes and patients' perceived change in overall health status after 12 months of treat-to-target in patients with early rheumatoid arthritis (RA) and to identify determinants of subjective nonimprovement. METHODS: Baseline and 12-month data of patients included in the Dutch Rheumatoid Arthritis Monitoring remission induction cohort study with at least a moderate response (by European League Against Rheumatism criteria) after 1 year were selected for analysis. Logistic regression analysis was used to identify factors associated with nonimproved perceived overall health status at 12 months. RESULTS: At 12 months, 75 of 210 patients (35%) did not consider their health to have improved despite having achieved favorable clinical outcomes. Relative change from baseline in pain (Wald = 20.20; P < 0.01) and fatigue (Wald = 5.58; P = 0.02) was independently associated with nonimproved perceived overall health status. The results were similar when only patients with ≤1 swollen joint were analyzed. An improvement of 55% in pain measured on a visual analog scale was found to discriminate reasonably well between patients who considered their health to have improved versus patients who did not, with an area under the receiver operating characteristic curve of 0.70 (95% confidence interval 0.61-0.78). CONCLUSION: These results demonstrate that clinical improvements do not equate with improved subjective health for all patients. The association of nonimprovement with changes in pain and fatigue suggest that it might be worthwhile to monitor and address pain and fatigue in addition to and independently of disease activity in early RA.

Expert evaluations of fatigue questionnaires used in rheumatoid arthritis: a Delphi study among patients, nurses and rheumatologists in the Netherlands.

OBJECTIVES: Evaluating fatigue items from traditional questionnaires and a new scale (BRAF-MDQ) by experts in rheumatoid arthritis (RA). This evaluation was part of a study to select fatigue items to develop an item bank for a Dutch computer-adaptive test (CAT) for RA. Experts' opinions were incorporated since they are essential for content validity of measurement instruments. METHODS: The 60 items of the SF-36 subscale vitality, FACIT-F, POMS subscale fatigue/inertia, MAF and the recently developed BRAF-MDQ were evaluated by rheumatologists, nurses and RA patients in a Delphi procedure. Items were selected for development of the item bank/CAT if rated as adequate by at least 80% of the participants (when 50% or less they were excluded). On the basis of participants' comments, remaining items were re-worded and re-evaluated in the following round. The procedure stopped when all items were selected or rejected. RESULTS: Ten rheumatologists, 20 nurses and 15 RA patients participated. After the first round, 40% of the traditional items and 60% of the BRAF-MDQ items were directly selected and 3 items of the traditional questionnaires and 1 item of the BRAF-MDQ were directly excluded. Remaining items were re-worded, eight of which were presented for re-evaluation in the second round. Finally, 90% of the items from the traditional questionnaires and 95% of the items from the new BRAF-MDQ were included in our item pool. CONCLUSIONS: Fifty-five of the 60 items (92%) from fatigue questionnaires proved to have good content validity and were feasible for use in the Netherlands, some after adaptation.

A review of instruments to assess illness representations in patients with rheumatic diseases.

OBJECTIVE: Critical appraisal of instruments to assess illness representations in rheumatology. METHODS: A first search (MEDLINE, EMBASE, PsycINFO) identified articles describing development of instruments assessing illness representations. A second search identified articles applying them in rheumatology. Appraisal was performed using checklists. RESULTS: Five instruments were identified: the Illness Perception Questionnaire (IPQ), the Revised Illness Perception Questionnaire (IPQ-R), the Illness Cognition Questionnaire (ICQ), the Implicit Models of Illness Questionnaire (IMIQ) and the Meaning of Illness Questionnaire (MIQ). The number of items varied from 18 to 70. Internal consistency was good. Construct validity was moderate to good for all instruments, but was not tested for the IMIQ. Predictive validity was assessed for the ICQ and IPQ and was low to moderate. Sensitivity to change was tested for ICQ and was good. Applications in rheumatology are increasing. Significant relationships with different outcomes and additional evidence for predictive validity were found. CONCLUSIONS: Five instruments that assess illness representations can be used in rheumatology. The number of subscales and items vary. The ICQ and IPQ are most extensively validated and have been most frequently applied in rheumatology. Illness representations have relevant associations with self-report and objective outcomes. They should be considered when exploring health in rheumatology.

Participation in online patient support groups endorses patients' empowerment.

OBJECTIVE: Although much has been expected of the empowering effect of taking part in online patient support groups, there is no direct evidence thus far for the effects of participation on patient empowerment. Hence our exploring to what extent patients feel empowered by their participation in online support groups, and which processes that occur in these groups are related to the empowering outcomes. METHODS: An online questionnaire was completed by 528 individuals who were active in online groups for patients with breast cancer, fibromyalgia and arthritis. RESULTS: The respondents felt empowered in several ways by their participation. The empowering outcomes that were experienced to the strongest degree were 'being better informed' and 'enhanced social well-being'. No significant differences in empowering outcomes between diagnostic groups were found. The empowering outcomes could only be predicted in a modest way by the processes that took place in the online support groups. CONCLUSION: This study indicates that participation in online support groups can make a valuable contribution to the empowerment of patients. PRACTICE IMPLICATIONS: Health care providers should acquaint their patients with the existence of online support groups and with the benefits that participation in these groups can offer.

Efficacy of wrist working splints in patients with rheumatoid arthritis: a randomized controlled study.

OBJECTIVE: To investigate the efficacy of wrist working splints after a period of splinting in patients with rheumatoid arthritis (RA). METHODS: We performed a 4-week randomized controlled trial among 33 RA patients with wrist arthritis. Patients were randomly allocated to the splinting group (n = 17) or the control group (n = 16). Patients in the splinting group received a prefabricated wrist working splint and were instructed to use this splint as much as possible during the day. The primary outcome measure was average wrist pain during the past week, measured using a visual analog scale (VAS). Secondary outcome measures were grip strength and functional ability. The latter was measured using the Disabilities of the Arm, Shoulder, and Hand questionnaire and the short version of the Sequential Occupational Dexterity Assessment. Measurements were performed at baseline and after 4 weeks. Performance tests were performed without splint. Differences in change scores between the splinting and the control group were analyzed using analysis of covariance. To indicate the magnitude of the treatment effects, effect sizes were calculated. RESULTS: A large and highly significant treatment effect on wrist pain was found. VAS pain scores decreased by 32% in the splinting group and increased by 17% in the control group. Small and nonsignificant treatment effects were found with regard to nonsplinted grip strength and functional ability. CONCLUSION: Prefabricated wrist working splints are highly effective in reducing wrist pain after 4 weeks of splint wearing in RA patients with wrist arthritis.

Psychometric properties of the Rheumatoid Arthritis Disease Activity Index (RADAI) in a cohort of consecutive Dutch patients with RA starting anti-tumour necrosis factor treatment.

OBJECTIVES: To examine the psychometric properties of the self-administered Dutch Rheumatoid Arthritis Disease Activity Index (RADAI) and its short form (RADAI-SF) in patients with rheumatoid arthritis starting anti-tumour necrosis factor treatment. METHOD: Internal consistency was assessed with Cronbach's alpha. A confirmatory factor analysis (CFA) was carried out to test the single-factor structure. Construct validity was examined by correlating RADAI and RADAI-SF scores with Disease Activity Score in 28 joints (DAS28). Internal responsiveness was evaluated with the paired t test and the standardised response mean (SRM). External responsiveness was assessed with receiver operating characteristic analysis and the SRM, using the EULAR response criterion as external criterion. Change scores were correlated with changes in DAS28. RESULTS: At baseline and after 3 months' treatment, respectively, 191 and 171 patients completed the RADAI. The internal consistency of the RADAI and the RADAI-SF was satisfactory. CFAs confirmed the single-factor structure of both RADAI versions, but the short form provided the best model fit. Moderate correlations were found with the DAS28. SRMs of the RADAI and the RADAI-SF were, respectively, 0.76 and 0.80. Both versions had moderate accuracy to distinguish responders from non-responders. Changes scores were moderately correlated with DAS28 change scores. CONCLUSIONS: This study showed satisfactory psychometric properties of the Dutch version of the RADAI. Omission of the tender joint count (RADAI-SF) produced comparable results and is justified for research purposes. The tender joint count might be useful as additional clinical information in patient management.

Arthritis patients show long-term benefits from 3 weeks intensive exercise training directly following hospital discharge.

OBJECTIVE: To examine the efficacy of short-term intensive exercise training (IET) directly following hospital discharge. METHODS: In the Disabled Arthritis Patients Post-hospitalization Intensive Exercise Rehabilitation (DAPPER) study, patients with rheumatoid arthritis or osteoarthritis were eligible when they needed hospitalization for either a flare-up in disease, elective hip or knee arthroplasty. The intervention group received IET for 3 weeks immediately after discharge; the control group was treated with the usual care (UC). The intensive exercise was provided in a resort. Outcomes were assessed at baseline, after 3, 13, 26 and 52 weeks. Range of motion was measured using the Escola Paulista de Medicina-Range of Motion scale (EPM-ROM), disability was measured using the HAQ and the McMaster Toronto Arthritis Patient Preference Disability Questionnaire (MACTAR), and for health-related quality of life (HRQoL), the Research and Development 36-Item Health Survey (RAND-36) was used. RESULTS: The IET showed a better and faster improvement than UC on all outcome measures except for HRQoL. Up to 52 weeks after baseline, the EPM-ROM and the MACTAR remained favourable in IET compared with UC. At 3 weeks, the MACTAR improved significantly more in the IET compared with the UC: mean difference -5.5 (95% CI -8.4 to -2.2). At 26 weeks, the mean difference remained significant (-5.2; 95% CI -10.0 to -0.34). At 52 weeks, the effect was not significant; however, the mean difference in improvement between the groups can be considered clinically relevant. At 3 weeks, the IET had improved significantly more on the HAQ walking and rising subscales. CONCLUSION: Intensive short-term exercise training of arthritis patients, immediately after hospital discharge results in improved regain of function. The DAPPER programme has a direct effect, which lasts up to 52 weeks.

Cost-effectiveness of Spa treatment for fibromyalgia: general health improvement is not for free.

OBJECTIVES: To estimate the cost-effectiveness of an adjuvant treatment course of spa treatment compared with usual care only in patients with fibromyalgia syndrome (FM). METHODS: 134 patients with FM, selected from a rheumatology outpatient department and from members of the Dutch FM patient association were randomly assigned to a 2(1/2) week spa treatment course in Tunisia or to usual care only. Results are expressed as quality-adjusted life years (QALYs) for a 6-month as well as a 12-month time horizon. Utilities were derived form the Short Form 6D (SF-6D) scores and the visual analogue scale (VAS) rating general health. Costs were reported from societal perspective. Mean incremental cost per patient and the incremental cost utility ratio (ICER) were calculated; 95% confidence intervals (CIs) were estimated using double-sided bootstrapping. RESULTS: The data of 128 (55 spa and 73 controls) of the 134 patients (96%) could be used for analysis. Improvement in general health was found in the spa group until 6 months of follow-up by both the SF-6D (AUC 0.32 vs 0.30, P < 0.05) and the VAS (AUC 0.23 vs 0.19, P < 0.01). After 1yr no significant between-group differences were found. Mean incremental cost of spa treatment was 1311 Euro per patient (95% CI 369-2439), equalling the cost of the intervention (thalassotherapy including airfare and lodging), or 885 Euro per patient based on a more realistic cost estimate. CONCLUSIONS: The temporary improvement in quality of life due to an adjuvant treatment course of spa therapy for patients with FM is associated with limited incremental costs per patient.

Can we assess baseline pain and global health retrospectively?

OBJECTIVE: To study the agreement between patients' actual baseline assessments of pain and global health before treatment and retrospective assessments collected 2 weeks after treatment. METHODS: Data were collected in a prospective study of 200 rheumatology outpatients treated with a local corticosteroid injection. At baseline and 2-week follow-up, localized pain and global health were assessed on 100 mm visual analogue scales. The follow-up questionnaire was extended with a retrospective assessment of pain and global health before treatment. RESULTS: At follow-up patients slightly overestimated the severity of pain and global health before treatment. Actual and retrospective assessments were adequately correlated (pain: r(r(r(s) = 0.73; global health: r(s) = 0.67). Bland-Altman analysis showed that both pain and global health were characterized by high intra-individual variation between actual and retrospective assessments, with the 95% limits of agreement (-37.3 to 32.3 mm for pain and -49.7 to 37.8 mm for global health) far exceeding proposed values for minimal clinically important differences. CONCLUSION: Over a 2-week interval, patients' retrospective assessments of baseline pain and global health are fairly accurate and adequately correlated with actual baseline scores. At the group level, retrospective assessments can provide acceptable data on baseline pain and global health. The wide variability between actual and retrospective assessments, however, indicates that even over short time intervals there is poor individual agreement between the two methods.

Validation of a Dutch translation of the fibromyalgia impact questionnaire.

OBJECTIVES: To validate a Dutch translation of the fibromyalgia impact questionnaire (FIQ). MATERIALS AND METHODS: Data were taken from two randomized clinical trials on Spa treatment and venlafaxine in fibromyalgia (FM). Participants completed the Dutch FIQ and a set of validated questionnaires for general health (RAND-36), depression (Beck depression inventory, BDI), pain (McGill pain questionnaire, MPQ) and fatigue (checklist individual strength, CIS). Internal consistency within the FIQ item 'physical functioning' was studied using Cronbach's alpha. Test-retest reliability was studied with intra-class-correlation (ICC) in a subsample of 76 control subjects over a 3 month period without specific intervention. Construct validity was evaluated by correlating the FIQ to other questionnaires. Sensitivity to change was studied using standardized response means (SRM). RESULTS: The study sample consisted of 213 women and 11 men (mean age 47 yrs, mean disease duration 11 yrs). Cronbach's alpha for the item 'physical functioning' was 0.91, indicating high internal consistency. Test-retest reliability was acceptable, with ICC ranging from 0.45 for 'morning tiredness' to 0.71 for 'physical function'. FIQ correlated significantly with the RAND-36, with Spearman's rho ranging from -0.60 to -0.70 for items measuring the same concept. Similar patterns of correlation were seen with MPQ, BDI and CIS. Sensitivity to change was sufficient, with SRM after Spa treatment ranging from 0.3 for 'work days missed' to 0.9 for 'days felt good'. Similar SRM were found in the venlafaxine trial for patients reporting general improvement. CONCLUSION: The Dutch FIQ is a valid instrument for measuring health status in FM, showing sufficient reliability, construct validity and responsiveness.

Spa treatment for primary fibromyalgia syndrome: a combination of thalassotherapy, exercise and patient education improves symptoms and quality of life.

OBJECTIVES: To study the effect of a combination of thalassotherapy, exercise and patient education in people with fibromyalgia. METHODS: Patients with fibromyalgia, selected from a rheumatology out-patient department and from members of the Dutch fibromyalgia patient association, were pre-randomized to receive either 2(1/2) weeks of treatment in a Tunisian spa resort, including thalassotherapy, supervised exercise and group education (active treatment) or treatment as usual (control treatment). Primary outcome measure was health-related quality of life, measured with the RAND-36 questionnaire. Secondary measures included the Fibromyalgia Impact Questionnaire, the McGill Pain Questionnaire, the Beck Depression Inventory, tender point score and a 6-min treadmill walk test. RESULTS: Fifty-eight participants receiving the active treatment reported significant improvement on RAND-36 physical and mental component summary scales. For physical health, differences from the 76 controls were statistically significant after 3 months, but not after 6 and 12 months. A similar pattern of temporary improvement was seen in the self-reported secondary measures. Tender point scores and treadmill walk tests improved more after active treatment, but did not reach significant between-group differences, except for walk tests after 12 months. CONCLUSIONS: A combination of thalassotherapy, exercise and patient education may temporarily improve fibromyalgia symptoms and health-related quality of life.

Sensitivity to change of AIMS2 and AIMS2-SF components in comparison to M-HAQ and VAS-pain.

OBJECTIVE: To examine sensitivity to change of Dutch versions of AIMS2 (arthritis impact measurement scales-2) and AIMS2-SF (short form) components, in comparison with M-HAQ (modified health assessment questionnaire) and the 100 mm visual analogue scale for pain (VAS-pain) in patients with rheumatoid arthritis. METHODS: 218 patients participated in a study on patient education. Participants completed the Dutch AIMS2, M-HAQ, and VAS-pain at baseline and after one year; 165 completed both assessments. The education programme did not have any effect on health status. Patients were classified according to change over one year in their responses to the AIMS2 question about general health perception: improved health (n = 32), no change (n = 101), and poorer health (n = 32). Changes in scores over one year were tested with paired t tests, and standardised response means were calculated for AIMS2 and AIMS2-SF components, M-HAQ total score, and VAS-pain in the three classifications of change in health perception. RESULTS: AIMS2 and AIMS2-SF physical, symptom, and affect components showed similar sensitivity to change. The physical and symptom components performed better than M-HAQ and VAS-pain. AIMS2 and AIMS2-SF social interaction and role components were not sensitive to changes in general health perception. The role component was only applicable in 63 patients, because the others were unemployed, disabled, or retired. CONCLUSIONS: AIMS2-SF is a good alternative to the AIMS2 long form for the assessment of health status in rheumatoid arthritis, and is preferable to M-HAQ and VAS-pain. Use of the AIMS2-SF makes it easier and less costly to collect data and reduces the burden on patients.

Patient education for adults with rheumatoid arthritis.

BACKGROUND: Because of the unpredictability people with arthritis face on a daily basis, patient education programmes have become an effective complement to traditional medical treatment giving people with arthritis the strategies and the tools necessary to make daily decisions to cope with the disease. OBJECTIVES: To assess the effectiveness of patient education interventions on health status in patients with rheumatoid arthritis. SEARCH STRATEGY: We searched MEDLINE, EMBASE and PsycINFO and the Cochrane Controlled Trials Register. A selection of review articles (see references) were examined to identify further relevant publications. There was no language restriction. SELECTION CRITERIA: Randomised controlled trials (RCT's) evaluating patient education interventions that included an instructional component and a non-intervention control group; pre- and post-test results available separately for RA, either in the publication or from the studies' authors; and study results presented in full, end-of-study report. MAIN RESULTS: Thirty-one studies with relevant data were included. We found significant effects of patient education at first follow-up for scores on disability, joint counts, patient global assessment, psychological status, and depression. A trend favouring patient education was found for scores on pain. Physician global assessment was not assessed in any of the included studies. The dimensions of anxiety and disease activity showed no significant effects. At final follow up no significant effects of patient education were found, although there was a trend favouring patient education for scores on disability. REVIEWER'S CONCLUSIONS: Patient education as provided in the studies reviewed here had small short-term effects on disability, joint counts, patient global assessment, psychological status and depression. There was no evidence of long-term benefits in adults with rheumatoid arthritis.

Outcome in adults with juvenile idiopathic arthritis. Comparison of the DUTCH-AIMS2 between JIA and RA.

OBJECTIVES: To compare outcome in adult patients with JIA in childhood with outcome in young adults with RA and to evaluate the use of the DUTCH-AIMS2 in adult JIA patients METHODS: A questionnaire containing the DUTCH-AIMS2 to assess health outcomes (answers ranging from 0-10: 0=best) was sent to 142 adults with JIA (18-40 years). These health outcomes were compared with those of 34 young RA patients (< or = 40 years) from former studies. The DUTCH-AIMS2 was tested for its reliability and validity in adult JIA patients. RESULTS: The response rate was 71%. Disease duration of JIA patients (mean 19.2+/-9.5 years) was longer than in young RA patients (mean 7.8+/-5.3 years). RA patients scored worse than JIA patients in all health status areas with the exception of mobility. The mean health outcome scores were low for all groups (< or = 4.80). The internal consistency and the validity of the DUTCH-AIMS2 were satisfactory. CONCLUSIONS: Overall, the health outcome of oligoarticular and polyarticular adult JIA and young RA patients was quite good. The DUTCH-AIMS2 can be used as an instrument in outcome studies in JIA patients.

Psychometric properties of a Dutch short form of the Arthritis Impact Measurement Scales 2 (Dutch-AIMS2-SF).

OBJECTIVE: To evaluate the reliability and validity of a Dutch version of the Arthritis Impact Measurement Scales 2 short form (AIMS2-SF) and examine the agreement between the AIMS2 and AIMS2-SF in rheumatoid arthritis (RA) patients. METHODS: Data were collected from 587 RA patients from three studies. Patients completed the Dutch-AIMS2, Modified Health Assessment Questionnaire (M-HAQ), and Visual Analogue Scale for pain (VAS-pain), and clinical data were collected to calculate the Disease Activity Score 28 (DAS28). Short-form component scores were calculated from the AIMS2 long-form data. In addition, a Modified Symptom component score was calculated by replacing item 42 with item 38 as was suggested by Haavardsholm et al. [7] for the Norwegian version. RESULTS: The internal consistency of the Physical, Symptom and Affect components was good (Cronbach's alpha= 0.75-0.87), moderate for the Role component (alpha=0.62) but rather low for the Social Interaction (0.51) component. Replacing item 33 with item 31 of the long-form AIMS2 increased internal consistency for the Social Interaction component to 0.63. Test-retest reliability of the AIMS2-SF components was high (intraclass correlation coefficients >0.70). Mean scores of the AIMS2-SF were generally close to those from the AIMS2, but the limits of agreement were rather wide. Both the Modified Symptom and Modified Social Interaction components showed better agreement than the original short-form components. Plots of differences between AIMS2 and AIMS2-SF against the mean of the two scores for the five components showed that the differences varied over the range of the measurements. Factor analysis confirmed the three-factor structure, with a physical, psychological and social dimension that has been found for the Dutch-AIMS2 long form. Correlations of the AIMS2-SF components with M-HAQ total score, functional class, VAS-pain and DAS28 were very similar to the correlations for the original AIMS2. CONCLUSION: The Dutch-AIMS2-SF, with Modified Symptom and Social Interaction components has good psychometric properties, similar to those of the Dutch-AIMS2 long form.

MAIN RESULTS: Twenty-four studies with relevant data were included. We found significant effects of patient education at first follow-up for scores on disability, joint counts, patient global assessment and psychological status. Physician global assessment was not assessed in any of the included studies. The two separate dimensions of psychological status: anxiety and depression showed no significant effects, nor did the dimensions of pain and disease activity. At final follow up no significant effects of patient education were found. REVIEWER'S CONCLUSIONS: Patient education as provided in the studies reviewed here had moderate short-term effects on patient global assessment, and small short-term effects on disability, joint counts and psychological status. There were no long-term benefits.

The general public's knowledge and perceptions about rheumatic diseases.

OBJECTIVE: In the Netherlands, the mass media pay little attention to rheumatic diseases. For this reason, it might be assumed that in general people know very little about rheumatic diseases and thus have an unrealistic image of them. The purpose of this study was to gain insight into the general public's knowledge and perceptions regarding rheumatic diseases in the Netherlands. METHODS: A questionnaire was sent by mail to a random sample of 1800 Dutch homes; the response was 658. Questions mainly focused on knowledge, attitudes, behavioural intentions and use of the mass media with regard to rheumatic diseases. RESULTS: The respondents gave the right answer to a mean of 8.2 statements out of 17 true/false statements regarding factual knowledge of rheumatic diseases. Respondents particularly underestimated the prevalence of rheumatic diseases and were unaware of several rheumatic disorders. Most respondents had rarely used the mass media to gain information about rheumatic diseases, but they did show a moderate interest in acquiring information. Knowledge correlated positively with the respondents' level of education, acquaintance with rheumatic patients, and use of the mass media. Knowledge correlated negatively with the idea that rheumatic patients are themselves able to influence the course of their disease. In general, respondents judged rheumatic diseases to be rather serious but did not feel very frightened or vulnerable of becoming a rheumatic patient. Fear of rheumatic diseases correlated positively with interest in information about rheumatic diseases, intentions of visiting a doctor if experiencing rheumatic complaints and helping rheumatic patients in daily life. CONCLUSIONS: This study found that the public in general do not know very much about rheumatic diseases, but they do have a moderate desire for more information about them. Furthermore, they do not feel frightened of being confronted with a rheumatic disorder. More information about rheumatic diseases in the media might lead to better knowledge and perception of rheumatic diseases among the general public.

Perceptions about perceived functional disabilities and pain of people with rheumatoid arthritis: differences between patients and their spouses and correlates with well-being.

OBJECTIVE: In this study we examined the differences in perceptions of the patient's health status between rheumatoid arthritis (RA) patients and their spouses, and correlates of these differences with patients' and spouses' well-being. METHODS: A sample of 188 couples with one member receiving treatment for RA were selected from the rheumatology clinics in Twente, The Netherlands. The mean age of both RA patients and spouses was 56 years. Respondents completed questionnaires, including estimations of both patients and spouses on the patient's functional disabilities and pain, and scales on affect and marital commitment for patients and spouses. RESULTS: Differences in estimations of patients and spouses were considerable. Both over- and underestimations of the patient's functional disabilities by the spouse were associated with the patient's poorer mental health status. Overestimations of the patient's functional disabilities were associated with poorer mental health among spouses. CONCLUSION: It is essential that any support intended by the spouse is in accordance with the patient's needs. If the patient's condition is misperceived by the spouse, this can lead to ineffective and inappropriate support being given.

Effects of increased and deregulated expression of cell division genes on the morphology and on antibiotic production of streptomycetes.

This paper describes the effects of increased expression of the cell division genes ftsZ, ftsQ, and ssgA on the development of both solid- and liquid-grown mycelium of Streptomyces coelicolor and Streptomyces lividans. Over-expression of ftsZ in S. coelicolor M145 inhibited aerial mycelium formation and blocked sporulation. Such deficient sporulation was also observed for the ftsZ mutant. Over-expression of ftsZ also inhibited morphological differentiation in S. lividans 1326, although aerial mycelium formation was less reduced. Furthermore, antibiotic production was increased in both strains, and in particular the otherwise dormant actinorhodin biosynthesis cluster of S. lividans was activated in liquid- and solid-grown cultures. No significant alterations were observed when the gene dosage of ftsQ was increased. Analysis by transmission electron microscopy of an S. coelicolor strain overexpressing ssgA showed that septum formation had strongly increased in comparison to wild-type S. coelicolor, showing that SsgA clearly influences Streptomyces cell division. The morphology of the hyphae was affected such that irregular septa were produced with a significantly wider diameter, thereby forming spore-like compartments. This suggests that ssgA can induce a process similar to submerged sporulation in Streptomyces strains that otherwise fail to do so. A working model is proposed for the regulation of septum formation and of submerged sporulation.
