Objective To determine the effect of a multidisciplinary lifestyle program in patients with RA with low–moderate disease activity. Methods In the 'Plants for Joints' (PFJ) parallel-arm, assessor-blind randomized controlled trial, patients with RA and 28-joint DAS (DAS28) ≥2.6 and ≤5.1 were randomized to the PFJ or control group. The PFJ group followed a 16-week lifestyle program based on a whole-food plant-based diet, physical activity and stress management. The control group received usual care. Medication was kept stable 3 months before and during the trial whenever possible. We hypothesized that PFJ would lower disease activity (DAS28). Secondary outcomes included anthropometric, metabolic and patient-reported measures. An intention-to-treat analysis with a linear mixed model adjusted for baseline values was used to analyse between-group differences. Results Of the 83 people randomized, 77 completed the study. Participants were 92% female with mean (s. d.) age of 55 (12) years, BMI of 26 (4) kg/m2 and mean DAS28 of 3.8 (0.7). After 16 weeks the PFJ group had a mean 0.9-point greater improvement of DAS28 vs the control group (95% CI 0.4, 1.3; P  < 0.0001). The PFJ intervention led to greater decreases in body weight (difference –3.9 kg), fat mass (–2.8 kg), waist circumference (–3 cm), HbA1c (–1.3 mmol/mol) and low-density lipoprotein (–0.32 mmol/l), whereas patient-reported outcome measures, blood pressure, glucose and other lipids did not change. Conclusion The 16-week PFJ multidisciplinary lifestyle program substantially decreased disease activity and improved metabolic status in people with RA with low–moderate disease activity.

Objective: Serious gaming is an upcoming and promising tool in prevention and health promotion. The aim of this experimental study was to examine whether health-related serious gaming could optimize food-related outcomes and physical activity. Design: Eighty-one healthy participants (80% female) were randomly allocated to an experimental condition, in which participants played serious games based on transferring information, priming and evaluative conditioning, for half an hour, or a control condition, in which participants played non-health-related computer games. Main outcome measures: The primary study outcome was self-reported food preference and self-reported food choice, assessed by the Food Choice Task with food pairs differing in healthiness, or in both healthiness and attractiveness. Secondary outcomes were actual food choice and physical activity. Results: A significantly healthier food preference for pairs differing in healthiness was found on the Food Choice Task in the experimental compared to the control condition. No significant differences were found on the other outcomes. Conclusions: This study provides preliminary support for the effects of serious gaming based on optimizing food preferences. More research is needed to confirm the present findings and to further elucidate and optimize the effects of serious gaming on health behaviours. [ABSTRACT FROM AUTHOR]

Background Previous studies have indicated decreased health-related quality of life (HRQoL) shortly after kidney donation, returning to baseline in the longer term. However, a subgroup of donors experiences persistent HRQoL problems. To identify which HRQoL aspects are impacted most by the donation and to identify at-risk donors, more specific insight into psychosocial donation consequences is needed. Methods The current study examined the HRQoL course, donor-perceived consequences of donation for donors, recipients and donor–recipient relationships, and regret up to 12 months post-donation in donors from seven Dutch transplantation centres. Kidney donor candidates (n  = 588) completed self-report questionnaires early in the screening procedure, of which 361 (61%) donated their kidney. Results Data for 230 donors (64%) with complete assessments before donation and 6 and 12 months post-donation were analysed. Results indicated that donor physical HRQoL was comparable at all time points, except for an increase in fatigue that lasted up to 12 months post-donation. Mental HRQoL decreased at 6 months post-donation, but returned to baseline at 12 months. Donors reported large improvements in recipient's functioning and a smaller influence of the recipient's kidney disease or transplantation on the donor's life over time. A subgroup experienced negative donation consequences with 14% experiencing regret 12 months post-donation. Predictors of regret were more negative health perceptions and worse social functioning 6 months post-donation. The strongest baseline predictors of higher fatigue levels after donation were more pre-donation fatigue, worse general physical functioning and a younger age. Conclusions Future research should examine predictors of HRQoL after donation to improve screening and to provide potential interventions in at-risk donors. [ABSTRACT FROM AUTHOR]

Objective To investigate the association between illness perceptions and disability both cross-sectionally and over 2 years in patients with hand OA. Methods Illness perceptions and self-reported disability were assessed at baseline and after 2 years in 384 patients with primary hand OA (mean age 61 years, 84% women, n = 312 with follow-up) with the Illness Perception Questionnaire – Revised (IPQ-R), Functional Index for Hand OA, Australian/Canadian Hand OA Index and HAQ. Risk ratios for high disability (highest quartile) at both time points were estimated for tertiles of IPQ-R dimensions, using Poisson regression. The mean IPQ dimension change difference between patients with and without disability progression (change Functional Index for Hand OA ⩾ 1, Australian/Canadian Hand OA Index > 1.4, HAQ > 0.22) was estimated with linear regression. Analyses were adjusted for age, Doyle index and baseline score. Results At baseline, stronger negative illness perceptions were associated with high disability. Baseline illness perceptions were also associated with high disability after 2 years, although adjustment made apparent that these associations were confounded by baseline disability status. Most illness perceptions changed over 2 years; understanding increased, OA was regarded as more chronic and fewer emotions and consequences and less personal and treatment control were experienced. The 2 year change in disability was different between patients with and without progression for the illness perceptions of more perceived consequences, symptoms, treatment control and emotions. Conclusion Illness perceptions seemed to be implicated in disability and its progression. Our results suggest that interventions could focus on improving baseline disability, potentially using illness perceptions to accomplish this goal. [ABSTRACT FROM AUTHOR]

In order to combat chronic immune disorders (CIDs), it is an absolute necessity to understand the bigger picture, one that goes beyond insights at a one disease, molecular, cellular, and static level. To unravel this bigger picture we advocate an integral, cross disciplinary approach capable of embracing the complexity of the field. This paper discusses the current knowledge on common pathways in CIDs including general psychosocial and lifestyle factors associated with immune functioning. We demonstrate the lack of more in depth psychosocial and lifestyle factors in current research cohorts and most importantly the need for an all encompassing analysis of these factors. The second part of the paper discusses the challenges of understanding immune system dynamics and effectively integrating all key perspectives on immune functioning, including the patient s perspective itself. This paper suggests the use of techniques from complex systems science in describing and simulating healthy or deviating behavior of the immune system in its biopsychosocial surroundings. The patient s perspective data are suggested to be generated by using specific narrative techniques. We conclude that to gain more insight into the behavior of the whole system and to acquire new ways of combatting CIDs, we need to construct and apply new techniques in the field of computational and complexity science, to an even wider variety of dynamic data than used in today s systems medicine [ABSTRACT FROM AUTHOR]

Background: eHealth interventions have the potential to increase the physical activity of users. However, their effectiveness varies, and they often have only short-term effects. A possible way of enhancing their effectiveness is to increase the positive outcome expectations of users by giving them positive suggestions regarding the effectiveness of the intervention. It has been shown that when individuals have positive expectations regarding various types of interventions, they tend to benefit from these interventions more.Objective: The main objective of this web-based study is to investigate whether positive suggestions can change the expectations of participants regarding the effectiveness of a smartphone physical activity intervention and subsequently enhance the number of steps the participants take during the intervention. In addition, we study whether suggestions affect perceived app effectiveness, engagement with the app, self-reported vitality, and fatigue of the participants.Methods: This study involved a 21-day fully automated physical activity intervention aimed at helping participants to walk more steps. The intervention was delivered via a smartphone-based app that delivered specific tasks to participants (eg, setting activity goals or looking for social support) and recorded their daily step count. Participants were randomized to either a positive suggestions group (69/133, 51.9%) or a control group (64/133, 48.1%). Positive suggestions emphasizing the effectiveness of the intervention were implemented in a web-based flyer sent to the participants before the intervention. Suggestions were repeated on days 8 and 15 of the intervention via the app.Results: Participants significantly increased their daily step count from baseline compared with 21 days of the intervention (t107=-8.62; P<.001) regardless of the suggestions. Participants in the positive suggestions group had more positive expectations regarding the app (B=-1.61, SE 0.47; P<.001) and higher expected engagement with the app (B=3.80, SE 0.63; P<.001) than the participants in the control group. No effects of suggestions on the step count (B=-22.05, SE 334.90; P=.95), perceived effectiveness of the app (B=0.78, SE 0.69; P=.26), engagement with the app (B=0.78, SE 0.75; P=.29), and vitality (B=0.01, SE 0.11; P=.95) were found. Positive suggestions decreased the fatigue of the participants during the 3 weeks of the intervention (B=0.11, SE 0.02; P<.001).Conclusions: Although the suggestions did not affect the number of daily steps, they increased the positive expectations of the participants and decreased their fatigue. These results indicate that adding positive suggestions to eHealth physical activity interventions might be a promising way of influencing subjective but not objective outcomes of interventions. Future research should focus on finding ways of strengthening the suggestions, as they have the potential to boost the effectiveness of eHealth interventions.Trial Registration: Open Science Framework 10.17605/OSF.IO/CWJES; https://osf.io/cwjes.

Background: Recently, internet-based cognitive behavioral therapy (ICBT) and serious gaming interventions have been suggested to enhance accessibility to interventions and engagement in psychological interventions that aim to promote health outcomes. Few studies, however, have investigated their effectiveness in the context of simulated real-life challenges.Objective: We aimed to examine the effectivity of a guided ICBT combined with a serious gaming intervention in improving self-reported psychophysiological and immunological health endpoints in response to psychophysiological and immune-related challenges.Methods: Sixty-nine healthy men were randomly assigned to the intervention condition, receiving ICBT combined with serious gaming for 6 weeks, or the control condition, receiving no intervention. Self-reported vitality was the primary endpoint. Other self-reported psychophysiological and immunological endpoints were assessed following various challenges, including a bacillus Calmette-Guérin vaccination evoking pro-inflammatory responses, 1 and 4 weeks after the intervention period.Results: Although the intervention did not affect vitality-associated parameters, self-reported sleep problems (P=.027) and bodily sensations (P=.042) were lower directly after the intervention compared with controls. Furthermore, wellbeing (P=.024) was higher in the intervention group after the psychophysiological challenges. Although no significant group differences were found for the psychophysiological and immunological endpoints, the data provided preliminary support for increased immunoglobulin antibody responses at the follow-up time points (P<.05). Differential chemokine endpoints between conditions were observed at the end of the test day.Conclusions: The present study provides some support for improving health endpoints with an innovative ICBT intervention. Future research should replicate and further extend the present findings by consistently including challenges and a wide range of immune parameters into the study design.Trial Registration: Nederlands Trial Register NTR5610; https://www.trialregister.nl/trial/5466.

Background: Patients with chronic somatic conditions face unique challenges accessing mental health care outside of their homes due to symptoms and physical limitations. Internet-based cognitive behavioral therapy (ICBT) has shown to be effective for various psychological conditions. The increasing number of recent trials need to be systematically evaluated and quantitatively analyzed to determine whether ICBT is also effective for chronic somatic conditions and to gain insight into the types of problems that could be targeted. Objective: Our goal was to describe and evaluate the effectiveness of guided ICBT interventions for chronic somatic conditions on general psychological outcomes, disease-related physical outcomes, and disease-related impact on daily life outcomes. The role of treatment length was also examined. Methods: PubMed, PsycINFO, and Embase were searched from inception until February 2012, by combining search terms indicative of effect studies, Internet, and cognitive behavioral therapy. Studies were included if they fulfilled the following six criteria: (1) randomized controlled trial, (2) Internet-based interventions, (3) based on cognitive behavioral therapy, (4) therapist-guided, (5) adult (≥18 years old) patients with an existing chronic somatic condition, and (6) published in English. 23 randomized controlled trials of guided ICBT were selected by 2 independent raters after reviewing 4848 abstracts. Demographic, clinical, and methodological variables were extracted. Standardized mean differences were calculated between intervention and control conditions for each outcome and pooled using random effects models when appropriate. Results: Guided ICBT was shown to improve all outcome categories with small effect sizes for generic psychological outcomes (effect size range 0.17-0.21) and occasionally larger effects for disease-specific physical outcomes (effect size range 0.07 to 1.19) and disease-related impact outcomes (effect size range 0.17-1.11). Interventions with a longer treatment duration (>6 weeks) led to more consistent effects on depression. Conclusions: Guided ICBT appears to be a promising and effective treatment for chronic somatic conditions to improve psychological and physical functioning and disease-related impact. The most consistent improvements were found for disease-specific outcomes, which supports the possible relevance of tailoring interventions to specific patient groups. Explorative analyses revealed that longer treatment length holds the promise of larger treatment effects for the specific outcome of depression. While the current meta-analysis focused on several chronic somatic conditions, future meta-analyses for separate chronic somatic conditions can further consolidate these results, also in terms of cost-effectiveness.
