Objective: To evaluate the cost-effectiveness of longstanding personalized exercise therapy compared with usual care in people with rheumatoid arthritis (RA) and severe functional disability., Method: In this cost-utility analysis of a randomized controlled trial (n = 215), with 1 year follow-up, the study population comprised individuals with RA and reported severe difficulties in performing basic daily activities. Assessments were at baseline, 12, 26, and 52 weeks, with measurements of costs including medical and non-medical costs as recorded by patients and healthcare providers. Quality-adjusted life-years (QALYs) were estimated using the EuroQol 5 dimensions 5 levels (EQ-5D-5L) and EuroQol Visual Analogue Scale (EQ-VAS). Costs and QALY differences were analysed according to the intention-to-treat principle using cost-effectiveness acceptability curves., Results: The 1 year societal costs were non-significantly in favour of the usual care group, with a small difference of €180 [95% confidence interval (CI) €-4493 to €4852]. The QALYs were non-significantly in favour of the intervention group, by 0.02 according to the EQ-5D-5L (95% CI -0.05 to 0.09) and by 0.04 according to the EQ-VAS (95% CI 0.00 to 0.08). For a willingness-to-pay threshold of €50 000 per QALY, the intervention was the cost-effective strategy with 60% certainty., Conclusion: This economic evaluation showed no clear economic preference for either group, as the intervention costs were higher in the intervention group, but partly compensated by other cost savings and improved QALYs. Despite severe RA, patients had better clinical outcomes compared with usual care, suggesting no economic reasons to refrain from exercise therapy., Trial Registration Number: Netherlands Trial Register NL8235, included in the International Clinical Trial Registry Platform (ICTRP) (https://trialsearch.who.int/Trial2.aspx?TrialID=NL8235).

Objective: To assess the duration, frequency, and content of individual physical therapy (PT) in patients with rheumatoid arthritis (RA) or axial spondyloarthritis (axSpA)., Method: In this cross-sectional study, an electronic questionnaire aimed at people with RA and axSpA was distributed through various communication channels of the Dutch Arthritis Foundation. It comprised questions on sociodemographic and health characteristics, received PT (currently and/or in the past year) and, if applicable, its duration, frequency, and content (active exercises, manual treatment, physical modalities, and/or counselling/education)., Results: The study included 257 and 94 patients with self-reported diagnoses of RA and axSpA, of whom 163 (63%) and 77 (82%) currently or had recently received individual PT. The duration of individual PT was long-term (> 3 months) in 79% of RA and 83% of axSpA patients, with an average frequency of once per week in most. Although active exercises and counselling/education were each reported by ≥ 73% of the patients with RA and axSpA who received long-term individual PT, passive treatment modalities were also often offered (≥ 89%), in particular massage, kinesiotaping, and/or passive mobilization. The same pattern was seen in patients receiving short-term PT., Conclusion: The majority of patients with RA and axSpA received PT currently or in the past year, usually individually, long-term, and at a frequency of once a week. Although active exercises and education are recommended in guidelines, passive treatment options that are not advised were relatively often reported. An implementation study to identify barriers and facilitators regarding adherence to clinical practice guidelines seems warranted.

Objective: Assessing the construct validity of the Patient-Reported Outcomes Measurement Information System Physical Function 10-Item Short Form (PROMIS PF-10) in a subpopulation of rheumatoid arthritis (RA) or axial spondyloarthritis (axSpA) patients with severe limitations in physical functioning (PF)., Method: RA/axSpA patients with severe functional limitations completed the PROMIS PF-10, Health Assessment Questionnaire - Disability Index (HAQ-DI for RA) or Bath Ankylosing Spondylitis Functional Index (BASFI for axSpA), 36-item Short Form Health Survey (SF-36), EuroQol 5-dimensions 5-level (index score, EQ-VAS), and performed the Six-Minute Walk Test (6MWT). Construct validity was assessed by computing Spearman rank or Pearson correlation coefficients and testing hypotheses about correlations between the PROMIS PF-10 and measures of PF and quality of life., Results: Data from 316 patients (180 RA/136 axSpA, 91.7%/47.8% female, mean ± sd age 58.6 ± 13.2/54.0 ± 11.3 years) were analysed. The median (IQR) PROMIS PF-10 score was 34.5 (31.4-37.6) in RA and 36.0 (32.8-38.3) in axSpA patients. The PROMIS PF-10 correlated strongly with the HAQ-DI, BASFI, and EQ-5D-5L index score (r > 0.6), moderately with the SF-36 Physical Component Summary score, EQ-VAS, and 6MWT (0.30 ≤ r ≤ 0.60), and weakly with the SF-36 Mental Component Summary score (r < 0.30). Five of six hypotheses (83%) were confirmed in both groups., Conclusion: The overall strong correlation of the PROMIS PF-10 with measures of PF and moderate to weak correlations with outcomes measuring different constructs were confirmed in subpopulations of RA and axSpA patients with severe functional limitations, supporting its construct validity.

Background: While some tools have been developed to estimate an individual's cognitive reserve (CR), no study has assessed the adequacy of the method used for assessing these CR proxy indicators. Therefore, we aimed to determine the most appropriate method to estimate CR by comparing two approaches: (1) the common assessment of CR proxies in the literature (e.g. years of education) and (2) the calculation of a comprehensive index based on most significant parameters used in the estimation of CR., Methods: Data on CR proxies (i.e. education, occupation, and leisure activities) were obtained in a sample of 204 older adults. Regression analyses were used to develop the two indices of CR (i.e. ICR-standard and ICR-detailed) and to determine which index best represented the level of one's CR., Results: The ICR-standard was calculated using a combination of the three most common measures of reserve in the literature: number of schooling years, complexity of the primary occupation, and amount of current participation in stimulating activities. The ICR-detailed was calculated using the most significant parameters (established in initial analyses) of CR: highest level of education combined with the number of training courses, last occupation, and amount of current participation in social and intellectual activities. The comparison of both indices showed that higher levels of ICR-standard and ICR-detailed were associated with a greater minimization of the effects of age on cognition. However, the ICR-detailed was more strongly associated to this minimization than the ICR-standard, suggesting that the ICR-detailed best reflect one's CR., Conclusions: This study is the first to show that it is of great importance to question methods measuring CR proxies in order to develop a clinical tool allowing a comprehensive and accurate estimation of CR.

Background: Although fever is recognised as a major presentation symptom at Emergency Departments (EDs) and is often used as a rationale for the institution of antibiotics, few studies describing patients with fever as the sole inclusion criterion at the ED of a general hospital have been performed. The objective of this study is to describe epidemiology of non-surgical febrile patients at the ED and to identify risk factors for adverse outcome., Methods: Blood, sputum, urine and faeces cultures, urine sediments and throat swaps for viral diagnostics were obtained from febrile ED patients. Outcome parameters were bacterial/viral infection, non-bacterial/non-viral infection, non-infectious febrile disease&semi; mortality, hospital admission, admission to the intensive care unit (ICU) and length of hospital stay., Results: 213 Patients were included (87.8% were hospitalised, 8.5% were admitted to ICU, 4.2% died). In 75 patients (35.2%), bacterial infection was confirmed&semi; in 78 patients (36.6%) bacterial infection was suspected. In nine patients (4.2%), viral diagnosis was confirmed; in six patients (2.8%), a viral condition was suspected. The most frequently encountered infection was bacterial pneumonia (58 patients, 27.2%). Only older age was correlated with mortality (ρ=0.176, p=0.01)., Conclusion: A majority of the febrile patients were admitted to the hospital, mostly for bacterial infection. An overall mortality rate of 4.2% was registered. Only a few risk factors for adverse outcome could be identified in this cohort. Overall, the outcome of patients presenting with fever at the ED is rather benign.

Prolactin may contribute to an atherogenic phenotype. Furthermore, previous studies have shown that prolactin levels increase in situations of acute stress and inflammation. We therefore aimed to investigate the relationship between prolactin, acute stress and inflammation in patients with myocardial infarction. We performed a case-control study in 40 patients with myocardial infarction and 39 controls, aged 41-84 years. Blood for assessment of prolactin and high sensitive C-reactive protein (hsCRP) was drawn at inclusion, that is, during the acute phase of the event, and 2-3 weeks later. Unexpectedly, prolactin levels at inclusion did not differ between cases and controls (7.0 ng/ml and 6.0 ng/ml, respectively, p=0.28). 2-3 weeks later prolactin levels in cases had not decreased. However, univariate regression analysis indicated that hsCRP is associated with prolactin levels (regression coefficient β 0.11; [95% CI 0.01; 0.21]; p=0.03) in cases during the acute phase of myocardial infarction. Our findings may suggest that prolactin is involved in the systemic inflammatory response, which takes place during myocardial infarction; however, this association may not be strong enough to induce higher prolactin levels in patients with myocardial infarction., (© Georg Thieme Verlag KG Stuttgart · New York.)

Lemierre's syndrome is a potentially fatal disease that usually presents with oropharyngeal infection, followed by sepsis, thrombosis of the internal jugular vein and septic emboli. Most cases are caused by the Gram-negative, anaerobic Fusobacterium necrophorum. We present two patients with an atypical presentation of Lemierre's syndrome and a review. These cases illustrate that a positive blood culture for F. necrophorum, even without the presence of clinical symptoms pointing towards thrombosis of the internal jugular vein, justifies further radiological testing for thrombophlebitis of the internal jugular vein.

Background: Influenza infections have been associated with procoagulant changes. Whether influenza infections lead to an increased risk of pulmonary embolism remains to be established., Methods: We conducted a nested case control study in a large cohort of patients with a clinical suspicion of having pulmonary embolism. Blood samples were collected to investigate the presence of influenza A and B by complement fixation assay (CFA). We compared case patients, in whom pulmonary embolism was proven (n = 102), to controls, in whom pulmonary embolism was excluded (n = 395). Furthermore, we compared symptoms of influenza-like illness in both patient groups 2 weeks prior to inclusion in the study, using the influenza-like illness (ILI) score, which is based on a questionnaire. We calculated the risk of pulmonary embolism associated with influenza infection., Results: The percentage of patients with influenza A was higher in the control group compared to the case group (4.3% versus 1.0%, respectively, odds ratio 0.22; 95% CI: 0.03-1.72). Influenza B was not detectable in any of the cases and was found in 3 of the 395 controls (0.8%). The ILI score was positive in 24% of the cases and 25% in the control persons (odds ratio 1.16, 95% CI: 0.67-2.01). We did not observe an association between the ILI score and proven influenza infection., Conclusion: In this clinical study, influenza infection was not associated with an increased risk of acute pulmonary embolism. The ILI score is non-specific in this clinical setting.

Respiratory viral infections increase inflammatory responses to concurrent or secondary bacterial challenges, thereby worsening disease outcome. This potentiation of inflammation is explained at least in part by IFN-gamma promoting increased sensitivity to TNF-alpha and LPS. We sought to determine whether and, if so, how IFN-gamma can modulate proinflammatory responses to TNF-alpha and LPS by epithelial cells, which are key effector cells in the airways. Preincubation of airway epithelial-like NCI-H292 cells with IFN-gamma resulted in a hyperresponsive IL-6 and IL-8 production to TNF-alpha and LPS. The underlying mechanism involved the induction of indoleamine 2,3-dioxygenase, which catabolized the essential amino acid, tryptophan. Depletion of tryptophan led to stabilization of IL-6 and IL-8 mRNA and increased IL-6 and IL-8 responses, whereas supplementing tryptophan largely restored these changes. This novel mechanism may be implicated in enhanced inflammatory responses to bacterial challenges following viral infection.
