Working with pain : sustainable work participation of workers with chronic nonspecific musculoskeletal pain

Dit proefschrift is een van de eerste studies specifiek gericht op mensen die blijven werken met chronische pijn aan het bewegingsapparaat. Unieke kennis over duurzame arbeidsparticipatie van werknemers met chronische pijn werd vergaard. Doel van dit promotieonderzoek was meer inzicht te krijgen in de groep mensen die werkt met pijn en te achterhalen hoe zij in staat zijn ondanks hun klachten te blijven werken. In het proefschrift staan kenmerken en determinanten beschreven van werknemers die doorwerken met chronische pijn, waardoor een completer beeld is ontstaan van arbeidsparticipatie bij mensen met chronische pijn aan het bewegingsapparaat. Uit de vergelijking van mensen die doorwerken ondanks chronische pijn en mensen met arbeidsverzuim die in revalidatiebehandeling komen met chronische pijn blijkt dat deze groepen op diverse factoren significant verschillen. In het onderzoek werd onder andere aangetoond dat de motivatie voor werk, zelfmanagementvaardigheden en het belang dat wordt toegekend aan pijn, belangrijke factoren zijn die werken met chronische pijn faciliteren. Chronische pijn op zichzelf is vaak niet de reden voor arbeidsverzuim, maar meestal spelen persoonlijke- en omgevingsfactoren daarin een beslissende rol. Deze factoren kunnen dienen als aangrijpingspunt voor het verhogen van duurzame inzetbaarheid en preventie van arbeidsverzuim van mensen met chronische pijn aan het bewegingsapparaat. De effectieve manier waarop deelnemende werknemers in het onderzoek met hun pijn omgingen en productief bleven, kan anderen inspireren aan het werk te blijven. Daarnaast biedt het onderzoek een nieuw referentiekader voor de bedrijfs-, verzekerings-, en revalidatiegeneeskunde. This thesis was one of the first studies that focused specifically on people who continued work with chronic nonspecific musculoskeletal pain (CMP), and collected (identified) unique data concerning sustainable work participation of workers with CMP. It provides a large range of characteristics of workers with CMP who continued work despite pain, which has added to our understanding of sustainable work participation in people suffering from CMP. Comparison of workers who continued work with CMP with sick listed workers with CMP admitted for rehabilitation revealed that these groups differ significantly on several factors. In this thesis, evidence was found that the workers’ motivation to work, self-management skills, and the attributed importance of pain on their (working) lives are important factors to manage staying at work with CMP. It is recommended to be aware of the fact that CMP standing on itself is often not the reason for sick leave and disability, but regularly personal and environmental factors play an additional decisive role. Because these factors can be influenced, they offer opportunity to promote staying at work. In the process of guiding workers back to work, the results of the project ‘Working with pain’ may be used. The findings of this thesis potentially contribute to promotion of sustained work participation and prevention of sick-leave in workers with CMP. The effective way workers in this project coped with CMP and remained productive, may inspire others in their efforts to stay work. Finally, this thesis offers a new reference for rehabilitation-, occupational-,and insurance medicine.

Physician-patient communication in rheumatology: a systematic review

The nature of physician–patient interaction can have a significant impact on patient outcomes through information-sharing and disease-specific education that can enhance patients’ active involvement in their care. The aim of this systematic review was to examine all the empirical evidence pertaining to aspects of physician–patient communication and its impact on patient outcomes. A systematic search of five electronic databases (MEDLINE, PsycINFO, EMBASE, CINAHL, and Web of Science) was undertaken from earliest record to December 2016. Studies were eligible if they: (1) included adult participants (18 years or over) with a diagnosis of a rheumatic condition; (2) were of quantitative, qualitative or mixed methods design; (4) were surveys, observational and interventional studies; (5) were published in the English language; and (6) reported findings on either various physician–patient communication aspects alone or in combination with physical and psychological outcomes. Searches identified 455 papers. Following full-text retrieval and assessment for eligibility and quality, ten studies were included in the review; six quantitative, one mixed methods, and three qualitative papers. Higher levels of trust in the physician and active patient participation in the medical consultation were linked to lower disease activity, better global health, less organ damage accrual, greater treatment satisfaction with fewer side effects from the medication, more positive beliefs about control over the disease, and about current and future health. Future research could focus on the design and implementation of interventions incorporating communications skills and patient-education training

Polyphyletic origin of the genus Physarum (Physarales, Myxomycetes) revealed by nuclear rDNA mini-chromosomal analysis and group I intron synapomorphy

Physarales represents the largest taxonomic order among the plasmodial slime molds (myxomycetes). Physarales is of particular interest since the two best-studied myxomycete species, Physarum polycephalum and Didymium iridis, belong to this order and are currently subjected to whole genome and transcriptome analyses. Here we report molecular phylogeny based on ribosomal DNA (rDNA) sequences that includes 57 Physarales isolates. The Physarales nuclear rDNA sequences were found to be loaded with 222 autocatalytic group I introns, which may complicate correct alignments and subsequent phylogenetic tree constructions. Phylogenetic analysis of rDNA sequences depleted of introns confirmed monophyly of the Physarales families Didymiaceae and Physaraceae. Whereas good correlation was noted between phylogeny and taxonomy among the Didymiaceae isolates, significant deviations were seen in Physaraceae. The largest genus, Physarum, was found to be polyphyletic consisting of at least three well supported clades. A synapomorphy, located at the highly conserved G-binding site of L2449 group I intron ribozymes further supported the Physarum clades. Our results provide molecular relationship of Physarales genera, species, and isolates. This information is important in further interpretations of comparative genomics nd transcriptomics. In addition, the result supports a polyphyletic origin of the genus Physarum and calls for a reevaluation of current taxonomy
