Extraskeletal Manifestations in Axial Spondyloarthritis Are Associated With Worse Clinical Outcomes Despite the Use of Tumor Necrosis Factor Inhibitor Therapy

Objective. To investigate the prevalence and 4-year incidence of acute anterior uveitis (AAU), inflammatory bowel disease (IBD) and psoriasis (PsO), and to explore associations of newly developed extraskeletal manifestations (ESMs) with clinical disease outcome in a large cohort of patients with axial spondyloarthritis (axSpA). Methods. All consecutive patients included in the Groningen Leeuwarden Axial Spondyloarthritis (GLAS) cohort between 2004 and 2011 were analyzed. History of ESMs at baseline and newly developed ESMs during 4-year follow-up were only recorded when diagnosis by an ophthalmologist, gastroenterologist, or dermatologist was present. Results. Of the 414 included patients with axSpA, 31.4% had a positive history of ≥ 1 ESMs: 24.9% AAU, 9.4% IBD, and 4.3% PsO. History of PsO was significantly associated with more radiographic damage, especially of the cervical spine. Of the 362 patients with 4-year follow-up data, 15.7% patients developed an ESM: 13.3% patients had AAU (of which 3.6% had a first episode and 9.7% had recurrent AAU), 1.9% developed IBD, and 0.8% developed PsO. Patients with newly developed ESMs (without history of ESMs) had worse Ankylosing Spondylitis Quality of Life scores (mean 10.0 vs. 5.8, P = 0.001), larger occiput-wall distance (median 6.3 vs. 2.0, P = 0.02) and more limited modified Schober test (mean 12.6 vs. 13.6, P = 0.01) after 4 years of follow-up. The majority of patients developing an ESM used anti–tumor necrosis factor therapy. Conclusion. History of ESMs was present at baseline in one-third of patients with axSpA. The 4-year incidence of ESMs was relatively low, but patients who developed a new ESM reported worse quality of life

Social connectedness in online and blended-learning communities

Increasing flexibilisation and personalisation of education creates challenges in terms of students’ social connectedness with each other, with the programme and with lecturers. For this reason, a team of researchers and professors from four universities of applied sciences in the Netherlands carried out research into how a sense of community can be created in learning communities. On the basis of a literature review and design-oriented research, we conducted experiments aimed at fostering social connectedness in eight learning communities. These learning communities were in the domains of Nursing, Healthcare and Welfare Teacher Training, Management in Care, Teacher Training, and Nutrition and Dietetics (part-time, full-time and dual programme variants). The above research resulted in this Social connectedness in Online and Blended Learning Communities guide, which consists of two parts. Part one outlines the seven design principles (focused on content, attitude and preconditions) which lecturers can work with in their role as facilitator. The lecturer can apply these design principles to promote social connectedness in online and blended learning communities, including when flexible student paths are involved. These design principles are supported by practical IT tools and working methods and are widely applicable. The design principles involved are: A. Getting to know each other B. Trust and cooperation C. Shared and common goals D. Willingness to participate E. Programme and instruction strategies F. Sharing information and knowledge G. Resources and preconditions. Part 2 consists of a methodological justification and substantiation of the research underpinning the guide as well as a description of the results and ends with a conclusion, discussion and recommendations for further research. The experiments showed that learning communities that were newly established or had changed in composition after some time mainly opted for design principles A. Getting to know each other and B. Trust and cooperation. Learning communities that had been active for a longer period chose mainly C. Shared and common goals. Further longitudinal and other research is needed to determine to what extent the design principles and the role of the facilitators can be applied in other domains (such as technology, economics, etc.)

Could SGLT2 Inhibitors Improve Exercise Intolerance in Chronic Heart Failure?

Despite the constant improvement of therapeutical options, heart failure (HF) remains associated with high mortality and morbidity. While new developments in guideline-recommended therapies can prolong survival and postpone HF hospitalizations, impaired exercise capacity remains one of the most debilitating symptoms of HF. Exercise intolerance in HF is multifactorial in origin, as the underlying cardiovascular pathology and reactive changes in skeletal muscle composition and metabolism both contribute. Recently, sodium-related glucose transporter 2 (SGLT2) inhibitors were found to improve cardiovascular outcomes significantly. Whilst much effort has been devoted to untangling the mechanisms responsible for these cardiovascular benefits of SGLT2 inhibitors, little is known about the effect of SGLT2 inhibitors on exercise performance in HF. This review provides an overview of the pathophysiological mechanisms that are responsible for exercise intolerance in HF, elaborates on the potential SGLT2-inhibitor-mediated effects on these phenomena, and provides an up-to-date overview of existing studies on the effect of SGLT2 inhibitors on clinical outcome parameters that are relevant to the assessment of exercise capacity. Finally, current gaps in the evidence and potential future perspectives on the effects of SGLT2 inhibitors on exercise intolerance in chronic HF are discussed

Pre- and post-Golgi translocation of glucosylceramide in glycosphingolipid synthesis

Glycosphingolipids are controlled by the spatial organization of their metabolism and by transport specificity. Using immunoelectron microscopy, we localize to the Golgi stack the glycosyltransferases that produce glucosylceramide (GlcCer), lactosylceramide (LacCer), and GM3. GlcCer is synthesized on the cytosolic side and must translocate across to the Golgi lumen for LacCer synthesis. However, only very little natural GlcCer translocates across the Golgi in vitro. As GlcCer reaches the cell surface when Golgi vesicular trafficking is inhibited, it must translocate across a post-Golgi membrane. Concanamycin, a vacuolar proton pump inhibitor, blocks translocation independently of multidrug transporters that are known to translocate short-chain GlcCer. Concanamycin did not reduce LacCer and GM3 synthesis. Thus, GlcCer destined for glycolipid synthesis follows a different pathway and transports back into the endoplasmic reticulum (ER) via the late Golgi protein FAPP2. FAPP2 knockdown strongly reduces GM3 synthesis. Overall, we show that newly synthesized GlcCer enters two pathways: one toward the noncytosolic surface of a post-Golgi membrane and one via the ER toward the Golgi lumen LacCer synthase

Anti-thymocyte globulin with CsA and MMF as GVHD prophylaxis in nonmyeloablative HLA-mismatched allogeneic HCT

Nonmyeloablative regimens are used for allogeneic hematopoietic cell transplantation (HCT) of older or medically unfit patients, but successful outcome is still hindered by graft-versus-host disease (GVHD), especially in the setting of HLA-mismatched HCT. New GVHD prophylaxis strategies are emerging, including the triple drug strategy, that improve the GVHD-free and relapse-free survival (GRFS). Because the impact of ATG in HLA-mismatched Flu-TBI-based nonmyeloablative HCT has not been investigated, we did a retrospective analysis in three Dutch centers. 67 patients were evaluable, with a median age of 56 years. Overall survival, relapse-free survival and GRFS at 4 years were 52%, 43%, and 38%, respectively. NRM findings and cumulative incidence of relapse at 4 years were 26% and 31%, respectively. At 1-year grade II-IV had occurred in 40% of the patients, and the incidence of moderate-severe chronic GVHD incidence was 16%. Acknowledging the limitations of retrospective analyses, we conclude that the use of ATG for HLA-mismatched truly nonmyeloablative Flu-TBI HCT is feasible and results in acceptable long term outcomes, especially with regards to GRFS. We consider ATG in combination with cyclosporin and mycophenolate mofetil as an alternative for the triple drug strategy that uses sirolimus for GVHD prophylaxis in this particular setting

Rosuvastatin use increases plasma fibrinolytic potential: a randomised clinical trial

We conducted a study to assess the effect of rosuvastatin use on fibrinolysis in patients with previous venous thromboembolism (VTE). This was a post hoc analysis within the STAtins Reduce Thrombophilia (START) study (NCT01613794). Plasma fibrinolytic potential, fibrinogen, plasmin inhibitor, plasminogen activator inhibitor-1 (PAI-1) and thrombin-activatable fibrinolysis inhibitor (

Rosuvastatin use reduces thrombin generation potential in patients with venous thromboembolism: a randomized controlled trial

Background Statin therapy could form an alternative prophylactic treatment for venous thromboembolism (VTE) if statins are proven to downregulate hemostasis and prevent recurrent VTE, without increasing bleeding risk. Objectives The STAtins Reduce Thrombophilia (START) trial investigated whether statin affects coagulation in patients with prior VTE. Patients/methods After anticoagulation withdrawal, patients were randomized to rosuvastatin 20 mg day−1 for 4 weeks or no intervention. Plasma samples taken at baseline and at the end of the study were analyzed employing thrombin generation assay. Results and conclusions The study comprised 126 rosuvastatin users and 119 non‐users. Mean age was 58 years, 61% were men, 49% had unprovoked VTE and 75% had cardiovascular (CV) risk factors. Endogenous thrombin potential (ETP) increased from baseline to end of study in non‐statin users (mean 97.22 nm*min; 95% CI, 40.92–153.53) and decreased in rosuvastatin users (mean −24.94 nm*min; 95% CI, −71.81 to 21.93). The mean difference in ETP change between treatments was −120.24 nm*min (95% CI, −192.97 to −47.51), yielding a 10.4% ETP reduction by rosuvastatin. The thrombin peak increased in both non‐statin (mean 20.69 nm; 95% CI, 9.80–31.58) and rosuvastatin users (mean 8.41 nm; 95% CI −0.86 to 17.69). The mean difference in peak change between treatments was −11.88 nm (95% CI, −26.11 to 2.35), yielding a 5% peak reduction by rosuvastatin. Other thrombin generation parameters did not change substantially. The reduction in ETP and peak by rosuvastatin was more pronounced in the subgroups of participants with CV risk factors and with unprovoked VTE. We conclude that rosuvastatin reduces thrombin generation potential in patients who had VTE

Cost impact of procalcitonin-guided decision making on duration of antibiotic therapy for suspected early-onset sepsis in neonates

Abstract Backgrounds The large, international, randomized controlled NeoPInS trial showed that procalcitonin (PCT)-guided decision making was superior to standard care in reducing the duration of antibiotic therapy and hospitalization in neonates suspected of early-onset sepsis (EOS), without increased adverse events. This study aimed to perform a cost-minimization study of the NeoPInS trial, comparing health care costs of standard care and PCT-guided decision making based on the NeoPInS algorithm, and to analyze subgroups based on country, risk category and gestational age. Methods Data from the NeoPInS trial in neonates born after 34 weeks of gestational age with suspected EOS in the first 72 h of life requiring antibiotic therapy were used. We performed a cost-minimization study of health care costs, comparing standard care to PCT-guided decision making. Results In total, 1489 neonates were included in the study, of which 754 were treated according to PCT-guided decision making and 735 received standard care. Mean health care costs of PCT-guided decision making were not significantly different from costs of standard care (€3649 vs. €3616). Considering subgroups, we found a significant reduction in health care costs of PCT-guided decision making for risk category ‘infection unlikely’ and for gestational age ≥ 37 weeks in the Netherlands, Switzerland and the Czech Republic, and for gestational age < 37 weeks in the Czech Republic. Conclusions Health care costs of PCT-guided decision making of term and late-preterm neonates with suspected EOS are not significantly different from costs of standard care. Significant cost reduction was found for risk category ‘infection unlikely,’ and is affected by both the price of PCT-testing and (prolonged) hospitalization due to SAEs

A cluster randomized controlled trial on the effects and costs of advance care planning in elderly care: Study protocol

Background: Currently, health care and medical decision-making at the end of life for older people are often insufficiently patient-centred. In this trial we study the effects of Advance Care Planning (ACP), a formalised process of timely communication about care preferences at the end of life, for frail older people. Methods/Design: We will conduct a cluster randomised controlled trial among older people residing in care homes or receiving home care in the Netherlands. The intervention group will receive the ACP program Respecting Choices® in addition to usual care. The control group will receive usual care only. Participants in both groups will fill out questionnaires at baseline and after 12 months. We hypothesize that ACP will lead to better patient activation in medical decision making and quality of life, while reducing the number of medical interventions and thus health care costs. Multivariate analysis will be used to compare differences between the intervention group and the control group at baseline and to compare differences in changes after 12 months following the inclusion. Discussion: Our study can contribute to more understanding of the effects of ACP on patient activation and quality of life in frail older people. Further, we will gain insight in the costs and cost-effectiveness of ACP. This study will facilitate ACP policy for older people in the Netherlands.
