Contains fulltext : 251159.pdf (Publisher’s version ) (Open Access), BACKGROUND: Systematically registering ADRs in electronic health records (EHRs) likely contribute to patient safety as it enables the exchange of drug safety data. Currently, ADRs registrations by healthcare professionals (HCPs) is suboptimal. This study aimed to identify barriers and facilitators perceived by HCPs to register ADRs systematically in EHRs. RESEARCH DESIGN AND METHODS: A qualitative study with individual interviews was conducted among specialist physicians and hospital pharmacists from 10 different Dutch hospitals. A semi-structured interview guide was used to identify experienced barriers and facilitators for systematically registering ADRs. Data was analyzed following thematic analysis. Themes within barriers and facilitators were aligned with the Capability-Opportunity-Motivation-Behavior (COM-B) framework. RESULTS: In total, 16 HCPs were interviewed. Identified barriers were: lack of knowledge to recognize ADRs, time constraints, inadequate IT system, lack of support, stuck in routine, and not recognizing the importance of registering ADRs. Identified facilitators were: enhanced knowledge and awareness of ADRs, functional IT systems, expanding accountability for registration, and motivation toward registering. CONCLUSIONS: Barriers and facilitators for registering spanned all aspects of the COM-B model and occurred in individual, social and environmental domains. Addressing these aspects could improve the registration of ADRs and may contribute to patient safety.

Objective Sarcoidosis, an inflammatory multi-organ disease with a wide variety of clinical manifestations, affecting people of working age. Patients suffer from a broad spectrum of physical symptoms of varying severity that impact function including cognitive impairment and disabling fatigue. The Dutch Sarcoidosis Society identified a knowledge gap in various facets related to work ability. The aim of this study was to assess sarcoidosis patients’ perceived problems related to work performance, employer, and disability evaluations. Methods A cross-sectional web-based anonymous survey was conducted among Dutch sarcoidosis patients recruited through sarcoidosis patient societies and outpatient sarcoidosis clinics. This investigation queried work performance, employer support, and disability evaluations. Results The study sample included 755 patients of whom 43% (n = 328) had undergone disability evaluation and were significantly more likely to experience extrapulmonary symptoms, severe fatigue, reduced exercise capacity along with memory problems and concentration problems with higher mean FAS and SFNSL-scores. Of these 328, 37% (n = 121) perceived they had not been listened to or taken seriously at assessments, and 38% (n = 124) disagreed with the outcome of disability assessments by benefits authorities; 75% (n = 93) appealed or requested re-assessment. Discussion A better understanding of sarcoidosis-related impact on work ability and quantification of disease burden is needed. Education for medical examiners and employers on sarcoidosis may improve quality of assessments and work accommodations. Development of guidelines for benefit authorities, which consider the broad impact of sarcoidosis beyond that of reduced pulmonary function, including extra-pulmonary assessment like fatigue, cognitive difficulties, as well as other organ involvement are needed.

Purpose The clinical manifestations of sarcoidosis vary widely, depending on the intensity of the inflammation and the organ systems affected. Hence, sarcoidosis patients may suffer from a great variety of symptoms. The aim of this study was to compare the self-reported burden of sarcoidosis patients in Denmark, Germany and the Netherlands, especially the prevalence of fatigue and small fiber neuropathy (SFN)-related symptoms, as well as differences in treatment strategies. Methods A cross-sectional web-based anonymous survey about complaints was conducted among sarcoidosis patients. Patients were invited to take part through the sarcoidosis patient societies as well as through outpatient sarcoidosis clinics in these countries. Results The questionnaire was completed by 1072 sarcoidosis patients (152 Danish, 532 German and 388 Dutch). Almost all patients reported having sarcoidosis-associated symptoms (organ-related as well as non-specific, non-organ related). Fatigue was reported by almost all respondents (90%), followed by pulmonary symptoms (72.4%). More than 50% of the respondents were being treated with prednisone, which was comparable in all three countries. In contrast, second- and third-line treatment differed substantially between Denmark, Germany and the Netherlands. Conclusion Sarcoidosis patients in Denmark, Germany and the Netherlands present with similar self-reported symptoms, organ-related as well as non-specific, non-organ related. Fatigue (90%) and symptoms associated with SFN (86%) were highly prevalent in all three countries.

Item does not contain fulltext, Background: Fatigue is a major and disabling problem in sarcoidosis. Knowledge concerning correlates of the development of fatigue and possible interrelationships is lacking. Objective: A conceptual model of fatigue was developed and tested. Methods: Sarcoidosis outpatients (n = 292) of Maastricht University Medical Center completed questionnaires regarding trait anxiety, depressive symptoms, cognitive failure, dyspnea, social support, and small fiber neuropathy (SFN) at baseline. Fatigue was assessed at 6 and 12 months. Sex, age, and time since diagnosis were taken from medical records. Pathways were estimated by means of path analyses in AMOS. Results: Everyday cognitive failure, depressive symptoms, symptoms suggestive of SFN, and dyspnea were positive predictors of fatigue. Fit indices of the model were good. Conclusions: The model validly explains variation in fatigue. Everyday cognitive failure and depressive symptoms were the most important predictors of fatigue. In addition to physical functioning, cognitive and psychological aspects should be included in the management of sarcoidosis patients.

OBJECTIVE: Epigenetic changes contribute to pancreatic neuroendocrine tumor (PanNET) development. Hypermethylation of promoter DNA as a cause of tumor suppressor gene silencing is a well-established oncogenic mechanism that is potentially reversible and therefore an interesting therapeutic target. Multiple endocrine neoplasia type 1 (MEN1) is the most frequent cause of inherited PanNETs. The aim of this study was to determine promoter methylation profiles in MEN1-related PanNETs.DESIGN AND METHODS: Methylation-specific multiplex ligation-dependent probe amplification was used to assess promoter methylation of 56 tumor suppressor genes in MEN1-related (n = 61) and sporadic (n = 34) PanNETs. Differences in cumulative methylation index (CMI), individual methylation percentages and frequency of promoter hypermethylation between subgroups were analyzed.RESULTS: We found promoter methylation of a large number of potential tumor suppressor genes. CMI (median CMI: 912 vs 876, P = 0.207) was the same in MEN1-related and sporadic PanNETs. We found higher methylation percentages of CASP8 in MEN1-related PanNETs (median: 59% vs 16.5%, P = 0.002). In MEN1-related non-functioning PanNETs, the CMI was higher in larger PanNETs (>2 cm) (median: 969.5 vs 838.5; P = 0.021) and in PanNETs with liver metastases (median: 1036 vs 869; P = 0.013). Hypermethylation of MGMT2 was more frequent in non-functioning PanNETs compared to insulinomas (median: 44.7% vs 8.3%; P = 0.022). Hypermethylation of the Von Hippel-Lindau gene promoter was observed in one MEN1-related PanNET and was associated with loss of protein expression.CONCLUSION: Promoter hypermethylation is a frequent event in MEN1-related and sporadic PanNETs. Targeting DNA methylation could be of therapeutic value in MEN1 patients with advanced PanNETs.

PURPOSE: Pancreatic neuroendocrine tumors are a major manifestation of multiple endocrine neoplasia type 1 (MEN1). This tumor syndrome is caused by germline mutations in MEN1, encoding menin. Insight into pathogenesis of these tumors might lead to new biomarkers and therapeutic targets for these patients. Several lines of evidence point towards a role for p27Kip1and p18Ink4cin MEN1-related tumor development in animal models for MEN1, but their contribution to human MEN1-related pancreatic neuroendocrine tumor development is not known.METHODS: In this study, we characterized protein expression of p27Kip1and p18Ink4cin human MEN1-related PanNETs by immunohistochemistry. From the nationwide DutchMEN1 Study Group database including > 90% of the Dutch MEN1 population, MEN1-patients, who underwent pancreatic surgery, were selected. A tissue micro-array was constructed with available paraffin tissue blocks, and PanNETs from 61 MEN1 patients were eligible for analysis.RESULTS: Expression of p27Kip1was high in 57 (93%) PanNETs and 67% of the tumors showed low expression of p18Ink4c(67.3%). No association was found between expression of either p27Kip1or p18Ink4cand clinic-pathological characteristics.CONCLUSIONS: These findings indicate that loss of p18Ink4c, but not p27Kip1, is a common event in the development of MEN1-related PanNETs. Restoration of p18Ink4cfunction through CDK4/6 inhibitors could be a therapeutic option for MEN1-related PanNETs.

OBJECTIVE: Human aging is accompanied by a decrease in growth hormone secretion and serum IGF-1 levels. Also, loss of muscle mass, strength and impairment of physical performance, ending in a state of frailty, are seen in elderly. We aimed to investigate whether handgrip strength, physical performance and recurrent falls are related to serum IGF-1 levels in community dwelling elderly.DESIGN: Observational cohort study (cross-sectional and prospective).METHODS: We studied the association between IGF-1 and handgrip strength, physical performance and falls in participants of the Longitudinal Aging Study Amsterdam. 1292 participants were included (633 men, 659 women). Serum IGF-1 levels were divided into quartiles (IGF-1-Q1 to IGF-1-Q4). Data on falls were collected prospectively for a period of three years. All analyses were stratified for age and physical activity and adjusted for relevant confounders.RESULTS: Men with a low physical activity score in IGF-1-Q1 and IGF-1-Q2 of the younger age group had a lower handgrip strength compared to IGF-1-Q4. In younger more active males in IGF-1-Q2 physical performance was worse. Recurrent fallers were less prevalent in older, low active males with low IGF-1 levels. In females, recurrent fallers were more prevalent in older, more active females in IGF-1-Q2. IGF-1 quartile may predict changes in handgrip strength and physical performance in men and women.CONCLUSIONS: Our results indicate that lower IGF-1 levels are associated with lower handgrip strength and worse physical performance, but less recurrent fallers especially in men. Associations were often more robust in IGF-1-Q2. Future studies on this topic are desirable.

Inspired by the works of the Dutch artist Piet Mondrian an Electric Mondrian has been developed built up from luminescent solar concentrator elements. It is based on differently colored square and rectangular elements of standard sizes based on multiples of 15 cm, as this the standard size of the c-Si cells that are used at the sides of the elements. This paper describes the design requirements and choices that have been made in detail. The design is based on commercially available luminescent concentrator Perspex plates and solar cells. Performance testing showed that at total size of 1 m2 a light-to-electric power device efficiency is measured of 0.2%: the Electric Mondrian thus provides ∼2 W in full sun, and two mobile devices can be charged directly or via a built-in battery. The Electric Mondrian functions as a decorative energy-harvesting element indoors in the urban environment, and can be marketed as such.

Luminescent solar concentrators consist of coloured plastic plates that concentrate sunlight to their sides where solar cells are mounted. Since their conception in the 1970s, novel dyes and nanocrystals have being developed for these concentrators, and it is time to show their full spectrum of colorful possibilities. In commemoration of the 100th birthday of the art movement “De Stijl”, of which the Dutch artist Piet Mondrian was a prominent member, van Sark et al. (article no. 1600015) have developed a Mondrian-inspired stained glass look-a-like window that serves as a solar energy harvesting device. It is based on luminescent solar concentrators, provides suffi cient power to charge mobile phones when placed in the windowsill and can also be used as an indoor decorative element. The authors describe in detail the design process of the “Electric Mondrian” and it is envisioned that similar designs will be deployed as building-integrated photovoltaic elements.

In this retrospective cohort study using the Clinical Practice Research Datalink (CPRD), patients with sarcoidosis have an increased risk of clinical vertebral fractures and when on recent treatment with oral glucocorticoids, also an increased risk of any fractures and osteoporotic fractures.INTRODUCTION: Sarcoidosis is a chronic inflammatory disease, in which fragility fractures have been reported despite normal BMD. The aim of this study was to assess whether patients with sarcoidosis have an increased risk of clinical fractures 84948983857compared to the general population.METHODS: A retrospective cohort study was conducted using the CPRD. All patients with a CPRD code for sarcoidosis between January 1987 and September 2012 were included. Cox proportional hazards models were used to derive adjusted relative risks (RRs) of fractures in all sarcoidosis patients compared to matched controls, and within the sarcoidosis group according to use and dose of systemic glucocorticoids.RESULTS: Five thousand seven hundred twenty-two sarcoidosis patients (mean age 48.0 years, 51 % females, mean follow-up 6.7 years) were identified. Compared to 28,704 matched controls, the risk of any fracture was not different in patients with sarcoidosis. However, the risk of clinical vertebral fractures was significantly increased (adj RR 1.77; 95 % CI 1.06-2.96) and the risk of non-vertebral fractures was decreased although marginally significant (adj RR 0.87; 95 % CI 0.77-0.99). Compared to sarcoidosis patients not taking glucocorticoids, recent use of systemic glucocorticoids was associated with an increased risk of any fracture (adj RR 1.50; 95 % CI 1.20-1.89) and of an osteoporotic fracture (adj RR 1.47; 95 % CI 1.07-2.02).CONCLUSIONS: Patients with sarcoidosis have an increased risk of clinical vertebral fractures, and when using glucocorticoid therapy, an increased risk of any fractures and osteoporotic fractures. In contrast, the risk of non-vertebral

Background Sarcoidosis patients suffer from fatigue and exercise limitation. The aim of this study was to establish whether a physical training program improves these and other outcomes important to sarcoidosis patients. Methods From 11/2012 to 9/2014, 201 sarcoidosis patients were referred to the ild care expertise team, Ede, the Netherlands. In our center, all patients are routinely recommended to undergo testing at baseline to determine their physical functioning and encouraged to complete a 12-week, supervised physical training program. Ninety patients underwent baseline testing and returned for repeat testing at 3 months in the interim, 49 completed the training program (Group I) and 41 chose not to participate (Group II). Change over time (from baseline to 3 months) in fatigue, exercise capacity, and skeletal muscle strength were assessed between the two groups. Results At baseline, there were no between-group differences for fatigue, DLCO %, FVC %, or exercise capacity [assessed by percent predicted six-minute walk distance (6MWD %) and Steep Ramp Test (SRT)]. The 6MWD for Group I improved between baseline and 3 months, while the 6MWD remained the same in Group II (F = 72.2, p < 0.001). Group I showed a significantly larger decrease of fatigue compared with Group II (F = 6.27, p = 0.014). Lung function tests did not change in either group. Conclusion A supervised physical training program improves exercise capacity and fatigue among sarcoidosis patients and should be included in their management regimen.

Item does not contain fulltext, Responsiveness to tumour necrosis factor (TNF) inhibitors has been associated with the TNF-alpha G-308A polymorphism in rheumatoid arthritis. The aim of this study was to examine the association between the presence of this polymorphism and the response to TNF inhibitors in patients with refractory sarcoidosis. Patients (n=111) who started TNF-inhibitor treatment (76 infliximab, 35 adalimumab) were followed for at least 1 year. The main symptoms in these patients were fatigue (n=100, 90.1%), small fibre neuropathy (n=91, 82.0%), pulmonary involvement (n=69, 62.2%), and/or uveitis (n=31, 27.9%). Patients were additionally genotyped for the presence of the TNF-alpha G-308A polymorphism. Treatment response was assessed using clinical outcome measures and questionnaires. Three-quarters (n=83, 74.8%) of the patients responded well. Of the patients without the variant A-allele 93.6% (73 out of 78, p<0.001) improved, while 30.3% (10 out of 33) of variant A-allele carriers responded favourably to TNF inhibitors. For patients with the GG-genotype, the probability of improving compared with remaining stable or deteriorating was three times higher (risk ratio 3.09, 95% CI 1.84-5.20). Sarcoidosis patients without the TNF-alpha -308A variant allele (GG-genotype) had a three-fold higher response to TNF inhibitors (adalimumab or infliximab). Further research is needed to evaluate the value of genotyping for the TNF-alpha G-308A polymorphism in order to tailor TNF-inhibitor treatment.

Item does not contain fulltext, PURPOSE OF REVIEW: Sarcoidosis is a systemic disease characterized by the formation of granulomas in various organs, mainly lungs and lymphatic system. Joint, muscle, and bone involvement is also rather common. Recent studies on its pathogenesis and therapeutic management are reviewed here. RECENT FINDINGS: The pathogenesis of sarcoidosis is not fully elucidated. An exaggerated granulomatous reaction after exposure to unidentified antigens in genetically susceptible individuals evokes a clinical situation which we call sarcoidosis. No firm guidelines exist on whether, when, and how treatment should be started. Treatment is dependent on the presentation and the distribution, extensiveness and severity of sarcoidosis. Treatment of Lofgren's triad-related symptoms starts with NSAIDs; in other more extensive manifestations of sarcoidosis, the initiating dosage of glucocorticosteroids is approximately 20 mg daily. In terms of evidence-based treatment for sarcoidosis, only a few randomized controlled trials have been done. There is no cure for chronic sarcoidosis, and treatment only changes the granulomatous process and its clinical consequences. SUMMARY: Identified associations of certain polymorphisms with severity of the disease and treatment response suggest future research questions as well as finding the cause(s) of sarcoidosis, and the elucidation of relevant biomarkers and new efficient treatments. Between 20 and 70% of patients need systemic therapy. The increased awareness of long-term side-effects of glucocorticosteroids and the emergence of new drugs have changed the treatment of sarcoidosis. Alternative or additional options to corticosteroids should be assessed. VIDEO ABSTRACT

Item does not contain fulltext, PURPOSE OF REVIEW: Although glucocorticosteroids are considered the first-line treatment in sarcoidosis, refractory cases require alternatives, such as methotrexate (MTX). The aim of this study was to develop, on behalf of the World Association of Sarcoidosis and Other Granulomatous Disorders (WASOG), multinational evidence-based recommendations for the use of MTX in sarcoidosis for routine clinical practice. RECENT FINDINGS: A systematic literature search was conducted and combined with the opinions of sarcoidosis experts worldwide to formulate the recommendations. An online survey concerning 10 clinical questions was sent through the WASOG newsletter to sarcoidosis experts. Agreement about the recommendations amongst the world's leading sarcoidologists was evaluated. A total of 237 articles were identified, 43 of which were included. Randomized controlled trial evidence supporting the use of MTX in sarcoidosis was limited. Forty-five per cent (113 of 250) of the sarcoidosis experts contacted completed the survey (Europe 55%, North America 26% and Asia 12%). Ten recommendations were formulated concerning the indications for use, starting dose, folic acid, work-up, contraindications, monitoring, administration options in case of adverse gastrointestinal effects, hepatotoxicity, long-term safety and use during pregnancy and breast feeding. SUMMARY: Ten multinational evidence-based recommendations for the use of MTX in sarcoidosis were developed, which are supported by the world's foremost sarcoidosis experts.
