Patients with cardiovascular risk factors can reduce their risk of cardiovascular disease by increasing their physical activity and their physical fitness. According to the guidelines for cardiovascular risk management, health professionals should encourage their patients to engage in physical activity. In this paper, we provide insight regarding the systematic development of a Web-based intervention for both health professionals and patients with cardiovascular risk factors using the development method Intervention Mapping. The different steps of Intervention Mapping are described to open up the “black box” of Web-based intervention development and to support future Web-based intervention development.

BackgroundPhysical exercise in cancer patients is a promising intervention to improve cognition and increase brain volume, including hippocampal volume. We investigated whether a 6-month exercise intervention primarily impacts total hippocampal volume and additionally hippocampal subfield volumes, cortical thickness and grey matter volume in previously physically inactive breast cancer patients. Furthermore, we evaluated associations with verbal memory.MethodsChemotherapy-exposed breast cancer patients (stage I-III, 2–4 years post diagnosis) with cognitive problems were included and randomized in an exercise intervention (n = 70, age = 52.5 ± 9.0 years) or control group (n = 72, age = 53.2 ± 8.6 years). The intervention consisted of 2x1 hours/week of supervised aerobic and strength training and 2x1 hours/week Nordic or power walking. At baseline and at 6-month follow-up, volumetric brain measures were derived from 3D T1-weighted 3T magnetic resonance imaging scans, including hippocampal (subfield) volume (FreeSurfer), cortical thickness (CAT12), and grey matter volume (voxel-based morphometry CAT12). Physical fitness was measured with a cardiopulmonary exercise test. Memory functioning was measured with the Hopkins Verbal Learning Test-Revised (HVLT-R total recall) and Wordlist Learning of an online cognitive test battery, the Amsterdam Cognition Scan (ACS Wordlist Learning). An explorative analysis was conducted in highly fatigued patients (score of ≥ 39 on the symptom scale ‘fatigue’ of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire), as previous research in this dataset has shown that the intervention improved cognition only in these patients.ResultsMultiple regression analyses and voxel-based morphometry revealed no significant intervention effects on brain volume, although at baseline increased physical fitness was significantly related to larger brain volume (e.g., total hippocampal volume: R = 0.32, B = 21.7 mm3, 95 % CI = 3.0 – 40.4). Subgroup analyses showed an intervention effect in highly fatigued patients. Unexpectedly, these patients had significant reductions in hippocampal volume, compared to the control group (e.g., total hippocampal volume: B = −52.3 mm3, 95 % CI = −100.3 – −4.4)), which was related to improved memory functioning (HVLT-R total recall: B = −0.022, 95 % CI = −0.039 – −0.005; ACS Wordlist Learning: B = −0.039, 95 % CI = −0.062 – −0.015).ConclusionsNo exercise intervention effects were found on hippocampal volume, hippocampal subfield volumes, cortical thickness or grey matter volume for the entire intervention group. Contrary to what we expected, in highly fatigued patients a reduction in hippocampal volume was found after the intervention, which was related to improved memory functioning. These results suggest that physical fitness may benefit cognition in specific groups and stress the importance of further research into the biological basis of this finding.

Chronic pain rehabilitation programs are aimed at helping patients to increase their functioning despite being in pain, thereby improving their quality of life. However, conversations between patients and practitioners about how the patient could deal with his/her pain and pain-related disabilities in a different way can be interactionally challenging. This study adopts a discursive psychological perspective to explore how pain-related disability is negotiated by patients and practitioners during consultations. The analysis shows that pain-related disability is treated by both patients and practitioners as negotiable rather than a fixed reality. Moreover, it shows that patients’ and practitioners’ negotiations of disability are subject to issues of agency, accountability, and blame, and it provides insight into the interactional dilemmas that are at stake, both for patients and practitioners. Revalidatieprogramma’s voor patiënten met chronische pijn zijn gericht op het verbeteren van het functioneren ondanks de pijn, waardoor kwaliteit van leven wordt bevorderd. Conversaties tussen patiënten en behandelaars over de manier waarop de patiënt kan omgaan met de pijn en gerelateerde beperkingen kunnen interactionele uitdagingen met zich meebrengen. Dit hoofdstuk verkent vanuit discursief-psychologisch perspectief hoe beperkingen worden onderhandeld door patiënten en behandelaars in consulten. De analyse toont aan dat de beperkingen worden behandeld als onderhandelbaar in plaats van als een onveranderbare werkelijkheid. Bovendien toont de analyse dat in deze onderhandelingen bepaalde issues relevant worden gemaakt, zoals ‘agency’, verantwoordelijkheid en schuld. Inzicht wordt geboden in de interactionele dilemma’s die op het spel staan voor zowel patiënten als behandelaars.
