Abstract
Traumatic hand injuries are represented in a large proportion of the patients treated at the out-patient department of occupational therapy in the VU University Medical Centre, Amsterdam. Most of the patients are referred to occupational therapy by specialists in the hospital. Information about the course of traumatic hand injuries regarding performance of daily activities is still limited. Research, focused on problems experienced by patients with hand injuries, may contribute to a better understanding of the course and rehabilitation of traumatic hand injuries. This article is a report of a cross-sectional observational study with the objective to: 1) describe the impact of traumatic injuries of the hand on daily activities and work participation six months after injury 2) to analyse the impact of demographic characteristics and type and severity of the injury on pain and ability to perform daily activities, and 3) to analyse the impact of demographic characteristics and type and severity of the injury on work participation and time off work (TOW). Fifty-eight patients completed a questionnaire six months after injury. The Disability of Arm, Shoulder and Hand (DASH) questionnaire was used to evaluate disability in daily activities. A Numeric Rating Scale (NRS) was used to evaluate pain. Patients showed a mean DASH score of 22.5 (±19.3). The experience of pain and ethnicity were predictors of disability (p<0.001). The average TOW was 10.3 weeks (± 8.3). There was a significant difference (p=0.005) in TOW between Dutch patients (7.6 ± 5.8) and patients of another ethnicity (20.0 ± 8.9). Despite the reported disabilities in performing daily activities, almost all patients (91%) returned to their occupations within six months after hand injury. It is suggested that, for optimal rehabilitation, it may be necessary to focus more attention on the cultural background of the patients and the problems experienced in daily activities. Integration of evaluative instruments in hand therapy practice is advocated to guide therapy sessions, to measure outcome and to anticipate long-term problems in daily activities in an early stage of treatment.

Abstract
In this paper the internal consistency and inter-observer reliability of the assessment of disabilities in stroke patients with apraxia is presented. Disabilities were assessed by means of observation of activities of daily living (ADL). The study was conducted at occupational therapy departments in general hospitals, rehabilitation centers and nursing homes in the Netherlands. Patients (n=42) diagnosed to have had a stroke in the left hemisphere and to have apraxia as well, participated in the study (48% male, aged 39–91). Guidelines were offered for the ADL-observation and the assessment of disabilities in these activities. The internal consistency of the scales is expressed by means of Cronbach's alpha and Mokken-scale analysis. The inter-observer reliability is expressed by means of percentage of agreement between two observers, Cohen's kappa and the intra-class correlation coefficient (ICC). The internal consistency of the observations is good: alpha is high (0.94). The Mokken-analysis confirms this finding: an H-coefficient of 0.58 and corresponding rho of 0.94 indicate a strong and reliable scale composed of the set of all ADL-observations. Results indicate that the inter-observer reliability can be considered fair to good: all kappa values were higher than 0.44; the maximum kappa was 0.95. Percentages of agreement vary between 60% and 96%. The ICC range from 0.62 to 0.98. The results of this study imply that the ADL-observations can be considered an internally consistent and reliable instrument for the assessment of disabilities in stroke patients with apraxia.

Abstract
Objective: To assess the reproducibility (reliability and inter-rater agreement) of the client-centred Canadian Occupational Performance Measure (COPM). Design: The COPM was administered twice, with a mean interval of seven days (SD 1.6, range 4-14), by two different occupational therapists. Data analysis was based on intraclass correlation coefficients, the Bland and Altman method and Cohen's weighted kappas. Setting: Occupational therapy departments of two university medical centres. Subjects: Consecutive clients, with various diagnoses, newly referred to the outpatient clinic of two occupational therapy departments, were included. They were all over 18 years of age and perceived limitations in more than one activity of daily life. Complete data on 95 clients were obtained: 31 men and 64 women. Results: Sixty-six per cent of the activities prioritized at the first assessment were also prioritized at the second assessment. The intraclass correlation coefficients were 0.67 (95% confidence interval (CI) 0.54-0.78) for the mean performance score and 0.69 (95% CI 0.56-0.79) for the mean satisfaction score. The limits of agreement were-2.5 to 2.4 for the mean performance score and-2.3 to 2.7 for the mean satisfaction score. For the separate prioritized problems, the weighted kappas ranged from 0.37 to 0.49. Conclusions: Inter-rater agreement of the prioritized problems was moderate. The reproducibility of the mean performance and satisfaction scores was moderate, but it was poor for the scores of the separate problems. Therefore, the mean scores should be used for individual assessment.

Abstract
BACKGROUND Tracking longitudinal measurements of growth and decline in lung function in patients with persistent childhood asthma may reveal links between asthma and subsequent chronic airflow obstruction. METHODS We classified children with asthma according to four characteristic patterns of lung-function growth and decline on the basis of graphs showing forced expiratory volume in 1 second (FEV1), representing spirometric measurements performed from childhood into adulthood. Risk factors associated with abnormal patterns were also examined. To define normal values, we used FEV1 values from participants in the National Health and Nutrition Examination Survey who did not have asthma. RESULTS Of the 684 study participants, 170 (25%) had a normal pattern of lung-function growth without early decline, and 514 (75%) had abnormal patterns: 176 (26%) had reduced growth and an early decline, 160 (23%) had reduced growth only, and 178 (26%) had normal growth and an early decline. Lower baseline values for FEV1, smaller bronchodilator response, airway hyperresponsiveness at baseline, and male sex were associated with reduced growth (P<0.001 for all comparisons). At the last spirometric measurement (mean [±SD] age, 26.0±1.8 years), 73 participants (11%) met Global Initiative for Chronic Obstructive Lung Disease spirometric criteria for lung-function impairment that was consistent with chronic obstructive pulmonary disease (COPD); these participants were more likely to have a reduced pattern of growth than a normal pattern (18% vs. 3%, P<0.001). CONCLUSIONS Childhood impairment of lung function and male sex were the most significant predictors of abnormal longitudinal patterns of lung-function growth and decline. Children with persistent asthma and reduced growth of lung function are at increased risk for fixed airflow obstruction and possibly COPD in early adulthood. (Funded by the Parker B.

Abstract
OBJECTIVE To determine the cost-effectiveness (CE) of exercise therapy (intervention group) compared to 'general practitioner (GP) care' (control group) in patients with hip osteoarthritis (OA) in primary care. METHOD This cost-utility analysis was conducted with 120 GPs in the Netherlands from the societal and healthcare perspective. Data on direct medical costs, productivity costs and quality of life (QoL) was collected using standardised questionnaires which were sent to the patients at baseline and at 6, 13, 26, 39 and 52 weeks follow-up. All costs were based on Euro 2011 cost data. RESULTS A total of 203 patients were included. The annual direct medical costs per patient were significantly lower for the intervention group (€ 1233) compared to the control group (€ 1331). The average annual societal costs per patient were lower in the intervention group (€ 2634 vs € 3241). Productivity costs were higher than direct medical costs. There was a very small adjusted difference in QoL of 0.006 in favour of the control group (95% CI: -0.04 to +0.02). CONCLUSION Our study revealed that exercise therapy is probably cost saving, without the risk of noteworthy negative health effects. TRIAL REGISTRATION NUMBER NTR1462.

Abstract
Psychological distress contributes to impaired quality of life in hematological cancer patients. Stepped care treatment, in which patients start with the least intensive treatment most likely to work and only receive more intensive interventions if needed, could improve distress. We aimed to evaluate the outcome of stepped care treatment on psychological distress and physical functioning in patients treated with autologous stem cell transplantation for hematological malignancies. In the present study, we performed a randomized clinical trial with two treatment arms: stepped care and care as usual. Baseline assessment and randomization occurred during pre-transplant hospitalization. Stepped care was initiated after 6 weeks, consisting of (1) watchful waiting, (2) Internet-based self-help intervention, and (3) face-to-face counseling/ psychopharmacological treatment/ referral. Follow-up measurements were conducted at 13, 30, and 42 weeks after transplantation. Stepped care (n = 47) and care as usual (n = 48) were comparable on baseline characteristics. The uptake of the intervention was low: 24 patients started with step 1, 23 with step 2, and none with step 3. Percentages of distressed patients ranged from 4.1 to 9.7 %. Ten percent of patients received external psychological or psychiatric care. No statistically significant differences were found between stepped care and care as usual on psychological distress or physical functioning in intention to treat analyses, nor in per protocol analyses. The stepped care program was not effective in decreasing psychological distress. The low intervention uptake, probably related to the low levels of psychological distress, offers an explanation for this outcome. Future research should take into account patients' specific care needs. Netherlands Trial Registry identifier: NTR1770.

Abstract
OBJECTIVE To assess the effectiveness of exercise therapy added to general practitioner (GP) care compared with GP care alone, in patients with hip osteoarthritis (OA) during 12 months follow-up. METHODS We performed a multi-center parallel pragmatic randomized controlled trial in 120 general practices in the Netherlands. 203 patients, aged ≥45 years, with a new episode of hip complaints, complying with the ACR criteria for hip OA were randomized to the intervention group (n = 101; GP care with additional exercise therapy) or the control group (n = 102; GP care only). GP care was given by patient's own GP. The intervention group received, in addition, a maximum of 12 exercise therapy sessions in the first 3 months and hereafter three booster sessions. Blinding was not possible. Primary outcomes were hip pain and hip-related function measured with the HOOS questionnaire (score 0-100). RESULTS The overall estimates on hip pain and function during the 12-month follow-up showed no between-group difference (intention-to-treat). At 3-months follow-up there was a statistically significant between-group difference for HOOS pain -3.7 (95% CI: -7.3; -0.2), effect size -0.23 and HOOS function -5.3 (95% CI: -8.9; -1.6), effect size -0.31. No adverse events were reported. CONCLUSIONS No differences were found during 12-months follow-up on pain and function. At 3-months follow-up, pain and function scores differed in favor of patients allocated to the additional exercise therapy compared with GP care alone.

Abstract
BACKGROUND In a double-blind, randomized, placebo-controlled birth cohort, we have recently shown a beneficial effect of Lactobacillus rhamnosus HN001 (HN001) for the prevention of eczema in children through to 6 years of age but no effect of Bifidobacterium animalis subsp lactis HN019 (HN019). OBJECTIVE Among this cohort of children, we aim to investigate whether these probiotics could modify the expression of genetic predisposition to eczema conferred by genetic variation in susceptibility genes. METHODS Thirty-three eczema susceptibility SNPs (in eleven genes) were genotyped in 331 children of European ancestry. RESULTS Children who carried a genetic variant that put them at a high risk of developing eczema were less likely to develop eczema if they had been randomized to the HN001 intervention group compared to those in the placebo group. HN019 was also able to protect against the effects of some SNPs. As well as modifying genetic susceptibility to childhood eczema, HN001 was also found to modify genetic susceptibility to eczema severity and atopy risk. CONCLUSION AND CLINICAL RELEVANCE This is the first study to show an effect of a probiotic on reducing eczema risk amongst those with particular eczema-associated genotypes. Our findings suggest that Lactobacillus rhamnosus HN001 may be particularly effective in preventing eczema in children with specific high-risk genotypes.

Abstract
BACKGROUND Altered serotonergic (5-HT) metabolism and visceral perception have been associated with the pathogenesis of irritable bowel syndrome (IBS). Aim of this preliminary study was to assess the effect of the direct precursor of 5-HT, 5-hydroxytryptophan (5-HTP), on systemic 5-HT metabolites and visceral perception and to assess potential differential responses between IBS and controls. METHODS 15 IBS patients and 15 healthy volunteers participated in this randomized double-blind placebo controlled study. Visceroperception was measured by rectal barostat. The 100 mg 5-HTP or placebo was ingested orally. Serotonergic metabolites were assessed in platelet poor plasma. KEY RESULTS 5-HTP induces rectal allodynia in a significant number of healthy controls; IBS patients exhibit lowered pain thresholds in both placebo and 5-HTP conditions. 5-HTP induces rectal hyperalgesia in hypersensitive but not in non-hypersensitive IBS patients. Administration of 5-HTP significantly increased plasma 5-HTP levels (p < 0.001), did not affect 5-HT levels (p > 0.05), while levels of the main metabolite of 5-HT, 5-hydroxyindoleacetic acid, increased significantly (p < 0.05) in both groups. The magnitude of these changes observed in 5-HT metabolites was significantly greater in IBS patients. CONCLUSIONS & INFERENCES Oral administration of 5-HTP induced significant alterations in systemic 5-HT metabolites that were accompanied by increased visceroperception of pain in controls and hypersensitive IBS patients. Changes in 5-HT metabolism appear to be important factors involved in visceral hypersensitivity as the 5-HTP-induced pro-nociceptive response was observed in all hypersensitive IBS patients and to a lesser magnitude in a significant number of healthy controls but in none of the non-hypersensitive IBS patients.

Abstract
OBJECTIVE Although physical exercise is the commonly recommended for osteoarthritis (OA) patients, the working mechanism behind the positive effects of physical exercise on pain and function is a black box phenomenon. In the present study we aimed to identify possible mediators in the relation between physical exercise and improvements of pain and function in OA patients. DESIGN A systematic search for all studies evaluating the effects of physical exercise in OA patients and select those that additionally reported the change in any physiological factor from pre-to post-exercise. RESULTS In total, 94 studies evaluating 112 intervention groups were included. Most included studies evaluated subjects with solely knee OA (96 out of 112 groups). Based on the measured physiological factors within the included studies, 12 categories of possible mediators were formed. Muscle strength and ROM/flexibility were the most measured categories of possible mediators with 61 and 21 intervention groups measuring one or more physiological factors within these categories, respectively. 60% (31 out of 52) of the studies showed a significant increase in knee extensor muscle strength and 71% (22 out of 31) in knee flexor muscle strength over the intervention period. All 5 studies evaluating extension impairments and 10 out of 12 studies (83%) measuring proprioception found a significant change from pre-to post-intervention. CONCLUSION An increase of upper leg strength, a decrease of extension impairments and improvement in proprioception were identified as possible mediators in the positive association between physical exercise and OA symptoms.
