Minimum Information about T Regulatory Cells: A Step toward Reproducibility and Standardization
- 2018
-
In: Frontiers in Immunology. - : Frontiers Media SA. - 1664-3224. ; 8
-
Journal article (peer-reviewed)abstract
- Cellular therapies with CD4+ T regulatory cells (Tregs) hold promise of efficacious treatment for the variety of autoimmune and allergic diseases as well as posttransplant complications. Nevertheless, current manufacturing of Tregs as a cellular medicinal product varies between different laboratories, which in turn hampers precise comparisons of the results between the studies performed. While the number of clinical trials testing Tregs is already substantial, it seems to be crucial to provide some standardized characteristics of Treg products in order to minimize the problem. We have previously developed reporting guidelines called minimum information about tolerogenic antigen-presenting cells, which allows the comparison between different preparations of tolerance-inducing antigen-presenting cells. Having this experience, here we describe another minimum information about Tregs (MITREG). It is important to note that MITREG does not dictate how investigators should generate or characterize Tregs, but it does require investigators to report their Treg data in a consistent and transparent manner. We hope this will, therefore, be a useful tool facilitating standardized reporting on the manufacturing of Tregs, either for research purposes or for clinical application. This way MITREG might also be an important step toward more standardized and reproducible testing of the Tregs preparations in clinical applications.

Testosterone Therapy and Its Monitoring in Adolescent Boys with Hypogonadism: Results of an International Survey from the I-DSD Registry
- 2021
-
In: Sexual development : genetics, molecular biology, evolution, endocrinology, embryology, and pathology of sex determination and differentiation. - : S. Karger AG. - 1661-5433. ; 15:4, s. 236-243
-
Journal article (peer-reviewed)abstract
- It is unclear whether testosterone replacement therapy (TRT) in adolescent boys, affected by a range of endocrine diseases that may be associated with hypogonadism, is particularly common. The aim of this study was to assess the contemporary practice of TRT in boys included in the I-DSD Registry. All participating centres in the I-DSD Registry that had boys between 10 and 18 years of age and with a condition that could be associated with hypogonadism were invited to provide further information in 2019. Information on 162 boys was collected from 15 centres that had a median (range) number of 6 boys per centre (1.35). Of these, 30 (19%) from 9 centres were receiving TRT and the median (range) age at the start was 12.6 years (10.8–16.2), with 6 boys (20%) starting at <12 years. Median (range) age of boys not on TRT was 11.7 years (10.7–17.7), and 69 out of 132 (52%) were <12 years. TRT had been initiated in 20 of 71 (28%) boys with a disorder of gonadal development, 3 of 14 (21%) with a disorder of androgen synthesis, and all 7 (100%) boys with hypogonadotropic hypogonadism. The remainder who did not have TRT included 15 boys with partial androgen insensitivity, 52 with non-specific XY DSD, and 3 with persistent Müllerian duct syndrome. Before starting TRT, liver function and blood count were checked in 19 (68%) and 18 boys (64%), respectively, a bone age assessment was performed in 23 (82%) and bone mineral density assessment in 12 boys (43%). This snapshot of contemporary practice reveals that TRT in boys included in the I-DSD Registry is not very common, whilst the variation in starting and monitoring therapy is quite marked. Standardisation of practice may lead to more effective assessment of treatment outcomes.

Striatal dopamine dissociates methylphenidate effects on value-based versus surprise-based reversal learning
- 2022
-
In: Nature communications. - : Springer Science and Business Media LLC. - 2041-1723. ; 13:1, s. 4962-
-
Journal article (peer-reviewed)abstract
- Psychostimulants such as methylphenidate are widely used for their cognitive enhancing effects, but there is large variability in the direction and extent of these effects. We tested the hypothesis that methylphenidate enhances or impairs reward/punishment-based reversal learning depending on baseline striatal dopamine levels and corticostriatal gating of reward/punishment-related representations in stimulus-specific sensory cortex. Young healthy adults (N = 100) were scanned with functional magnetic resonance imaging during a reward/punishment reversal learning task, after intake of methylphenidate or the selective D2/3-receptor antagonist sulpiride. Striatal dopamine synthesis capacity was indexed with [18F]DOPA positron emission tomography. Methylphenidate improved and sulpiride decreased overall accuracy and response speed. Both drugs boosted reward versus punishment learning signals to a greater degree in participants with higher dopamine synthesis capacity. By contrast, striatal and stimulus-specific sensory surprise signals were boosted in participants with lower dopamine synthesis. These results unravel the mechanisms by which methylphenidate gates both attention and reward learning.

Effect of ticagrelor on the outcomes of patients with prior coronary artery bypass graft surgery : Insights from the PLATelet inhibition and patient outcomes (PLATO) trial
- 2013
-
In: American Heart Journal. - : Elsevier BV. - 0002-8703 .- 1097-6744. ; 166:3, s. 474-480
-
Journal article (peer-reviewed)abstract
- Background Patients with prior coronary artery bypass graft surgery (CABG) who present with an acute coronary syndrome have a high risk for recurrent events. Whether intensive antiplatelet therapy with ticagrelor might be beneficial compared with clopidogrel is unknown. In this substudy of the PLATO trial, we studied the effects of randomized treatment dependent on history of CABG. Methods Patients participating in PLATO were classified according to whether they had undergone prior CABG. The trial's primary and secondary end points were compared using Cox proportional hazards regression. Results Of the 18,613 study patients, 1,133 (6.1%) had prior CABG. Prior-CABG patients had more high-risk characteristics at study entry and a 2-fold increase in clinical events during follow-up, but less major bleeding. The primary end point (composite of cardiovascular death, myocardial infarction, and stroke) was reduced to a similar extent by ticagrelor among patients with (19.6% vs 21.4%; adjusted hazard ratio [HR], 0.91 [0.67, 1.24]) and without (9.2% vs 11.0%; adjusted HR, 0.86 [0.77, 0.96]; P-interaction = .73) prior CABG. Major bleeding was similar with ticagrelor versus clopidogrel among patients with (8.1% vs 8.7%; adjusted HR, 0.89 [0.55, 1.47]) and without (11.8% vs 11.4%; HR, 1.08 [0.98, 1.20]; P-interaction =.46) prior CABG. Conclusions Prior-CABG patients presenting with acute coronary syndrome are a high-risk cohort for death and recurrent cardiovascular events but have a lower risk for major bleeding. Similar to the results in no-prior-CABG patients, ticagrelor was associated with a reduction in ischemic events without an increase in major bleeding.

Diagnostic and predictive value of Doppler ultrasound for evaluation of the brain circulation in preterm infants: a systematic review
- 2020

Journal article (peer-reviewed)abstract
- IntroductionVery and extremely preterm infants frequently have brain injury-related long-term neurodevelopmental problems. Altered perfusion, for example, seen in the context of a hemodynamically significant patent ductus arteriosus (PDA), has been linked to injury of the immature brain. However, a direct relation with outcome has not been reviewed systematically.MethodsA systematic review was conducted to provide an overview of the value of different cerebral arterial blood flow parameters assessed by Doppler ultrasound, in relation to brain injury, to predict long-term neurodevelopmental outcome in preterm infants.ResultsIn total, 23 studies were included. Because of heterogeneity of studies, a meta-analysis of results was not possible. All included studies on resistance index (RI) showed significantly higher values in subjects with a hemodynamically significant PDA. However, absolute differences in RI values were small. Studies using Doppler parameters to predict brain injury and long-term neurodevelopmental outcome were inconsistent.DiscussionThere is no clear evidence to support the routine determination of RI or other Doppler parameters in the cerebral arteries to predict brain injury and long-term neurodevelopmental outcome in the preterm infant. However, there is evidence that elevated RI can point to the presence of a hemodynamically significant PDA.

Caring for individuals with a difference of sex development (DSD): a Consensus Statement
- 2018
-
In: Nature reviews. Endocrinology. - : Springer Science and Business Media LLC. - 1759-5037 .- 1759-5029. ; 14:7, s. 415-429

Journal article (peer-reviewed)abstract
- The term differences of sex development (DSDs; also known as disorders of sex development) refers to a heterogeneous group of congenital conditions affecting human sex determination and differentiation. Several reports highlighting suboptimal physical and psychosexual outcomes in individuals who have a DSD led to a radical revision of nomenclature and management a decade ago. Whereas the resulting recommendations for holistic, multidisciplinary care seem to have been implemented rapidly in specialized paediatric services around the world, adolescents often experience difficulties in finding access to expert adult care and gradually or abruptly cease medical follow-up. Many adults with a DSD have health-related questions that remain unanswered owing to a lack of evidence pertaining to the natural evolution of the various conditions in later life stages. This Consensus Statement, developed by a European multidisciplinary group of experts, including patient representatives, summarizes evidence-based and experience-based recommendations for lifelong care and data collection in individuals with a DSD across ages and highlights clinical research priorities. By doing so, we hope to contribute to improving understanding and management of these conditions by involved medical professionals. In addition, we hope to give impetus to multicentre studies that will shed light on outcomes and comorbidities of DSD conditions across the lifespan.

Characterising and predicting bleeding in high-risk patients with an acute coronary syndrome
- 2015
-
In: Heart. - : BMJ. - 1355-6037 .- 1468-201X. ; 101:18, s. 1475-1484
-
Journal article (peer-reviewed)abstract
- Objective In the Apixaban for Prevention of Acute Ischemic Events (APPRAISE-2) trial, the use of apixaban, when compared with placebo, in high-risk patients with a recent acute coronary syndrome (ACS) resulted in a significant increase in bleeding without a reduction in ischaemic events. The aim of this analysis was to provide further description of these bleeding events and to determine the baseline characteristics associated with bleeding in high-risk post-ACS patients. Methods APPRAISE-2 was a multinational clinical trial including 7392 high-risk patients with a recent ACS randomised to apixaban (5 mg twice daily) or placebo. Bleeding including Thrombolysis in Myocardial Infarction (TIMI) major or minor bleeding, International Society on Thrombosis and Haemostasis (ISTH) major or clinically relevant non-major (CRNM) bleeding, and any bleeding were analysed using an on-treatment analysis. Kaplan-Meier curves were plotted to describe the timing of bleeding, and a Cox proportional hazards model was used to identify predictors of ISTH major or CRNM bleeding and any bleeding. Median follow-up was 241 days. Results The proportion of patients who experienced TIMI major or minor, ISTH major or CRNM, and any bleeding was 1.5%, 2.2% and 13.3%, respectively. The incidence of bleeding was highest in the immediate post-ACS period (0.11 in the first 30 days vs 0.03 after 30 days events per 1 patient-year); however, > 60% of major bleeding events occurred > 30 days after the end of the index hospitalisation. Gastrointestinal bleeding was the most common cause of major bleeding, accounting for 45.9% of TIMI major or minor and 39.5% of ISTH major or CRNM bleeding events. Independent predictors of ISTH major or CRNM bleeding events included older age, renal dysfunction, dual oral antiplatelet therapy, smoking history, increased white cell count and coronary revascularisation. Conclusions When compared with placebo, the use of apixaban is associated with an important short-term and long-term risk of bleeding in high-risk post-ACS patients, with gastrointestinal bleeding being the most common source of major bleeding. The baseline predictors of major bleeding appear to be consistent with those identified in lower-risk ACS populations with shorter-term follow-up.

Journal article (peer-reviewed)abstract
- Background Extensive coronary artery disease (CAD) is associated with higher risk. In this substudy of the PLATO trial, we examined the effects of randomized treatment on outcome events and safety in relation to the extent of CAD. Methods Patients were classified according to presence of extensive CAD (defined as 3-vessel disease, left main disease, or prior coronary artery bypass graft surgery). The trial's primary and secondary end points were compared using Cox proportional hazards regression. Results Among 15,388 study patients for whom the extent of CAD was known, 4,646 (30%) had extensive CAD. Patients with extensive CAD had more high-risk characteristics and experienced more clinical events during follow-up. They were less likely to undergo percutaneous coronary intervention (58% vs 79%, P < .001) but more likely to undergo coronary artery bypass graft surgery (16% vs 2%, P < .001). Ticagrelor, compared with clopidogrel, reduced the composite of cardiovascular death, myocardial infarction, and stroke in patients with extensive CAD (14.9% vs 17.6%, hazard ratio [HR] 0.85 [0.73-0.98]) similar to its reduction in those without extensive CAD (6.8% vs 8.0%, HR 0.85 [0.74-0.98], P-interaction = .99). Major bleeding was similar with ticagrelor vs clopidogrel among patients with (25.7% vs 25.5%, HR 1.02 [0.90-1.15]) and without (7.3% vs 6.4%, HR 1.14 [0.98-1.33], P-interaction = .24) extensive CAD. Conclusions Patients with extensive CAD have higher rates of recurrent cardiovascular events and bleeding. Ticagrelor reduced ischemic events to a similar extent both in patients with and without extensive CAD, with bleeding rates similar to clopidogrel.

Journal article (peer-reviewed)abstract
- <b><i>Background:</i></b> Information sharing in chronic conditions such as disorders of/differences in sex development (DSD) is essential for a comprehensive understanding by parents and patients. We report on a qualitative analysis of communication skills of fellows undergoing training in paediatric endocrinology. Guidelines are created for the assessment of communication between health professionals and individuals with DSD and their parents. <b><i>Methods:</i></b> Paediatric endocrinology fellows worldwide were invited to study two interactive online cases (www.espe-elearning.org) and to describe a best practice communication with (i) the parents of a newborn with congenital adrenal hyperplasia and (ii) a young woman with 46,XY gonadal dysgenesis. The replies were analysed regarding completeness, quality, and evidence of empathy. Guidelines for structured assessment of responses were developed by 22 senior paediatric endocrinologists worldwide who assessed 10 selected replies. Consensus of assessors was established and the evaluation guidelines were created. <b><i>Results:</i></b> The replies of the fellows showed considerable variation in completeness, quality of wording, and evidence of empathy. Many relevant aspects of competent clinical communication were not mentioned; 15% (case 1) and 17% (case 2) of the replies were considered poor/insufficient. There was also marked variation between 17 senior experts in the application of the guidelines to assess communication skills. The guidelines were then adjusted to a 3-level assessment with empathy as a separate key item to better reflect the qualitative differences in the replies and for simplicity of use by evaluators. <b><i>Conclusions:</i></b> E-learning can play an important role in assessing communication skills. A practical tool is provided to assess how information is shared with patients with DSD and their families and should be refined by all stakeholders, notably interdisciplinary health professionals and patient representatives.

In: BRAZILIAN JOURNAL OF PHYSICAL THERAPY. - 1413-3555 .- 1809-9246. ; 28:1
-
Journal article (peer-reviewed)abstract
- Background: In 2013, physical therapy students demonstrated low guideline -adherent recommendations regarding chronic low back pain (CLBP) for spinal pathology, activity, and work. Objectives: To assess the differences in physical therapy students' attitudes, beliefs, and adherence to guideline recommendations regarding CLBP and knee osteoarthritis between 2013 and 2020. Methods: In 2013 and 2020, second and fourth -year physical therapy students were recruited from 6 Belgian and 2 Dutch institutions. Attitudes and beliefs regarding CLBP and knee OA were evaluated using the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT), the Health Care Providers' Pain and Impairment Relationship Scale (HC -PAIRS), and a questionnaire regarding therapeutic exercise and knee osteoarthritis. A clinical vignette was used to measure guideline -adherent recommendations regarding spinal pathology, activity, and work. Results: In 2013, 927 second -year and 695 fourth -year students; in 2020, 695 second -year and 489 fourth -year students; were recruited to participate in the study. Compared to 2013, students had less biomedical and stronger biopsychosocial attitudes and beliefs regarding CLBP, more guideline -adherent recommendations for activity, and more biopsychosocial beliefs regarding the benefits of exercise for patients with knee osteoarthritis in both the second and fourth year. Only fourth -year students in 2020 scored significantly better on HC -PAIRS and guideline -adherent recommendation relating to spinal pathology. No differences were found regarding work recommendations. Conclusions: Between 2013 and 2020, physical therapy students made a positive shift towards a more biopsychosocial approach to CLBP and knee osteoarthritis management. Guideline -adherent recommendations for CLBP concerning activity improved, however, concerning work and spinal pathology, it remained low.

Journal article (peer-reviewed)abstract
- Background: Randomized trials have confirmed the efficacy of prucalopride for the treatment of chronic constipation up to 12 weeks. This study aimed to assess the efficacy of prucalopride over a 24-week period (ClinicalTrials.gov: NCT01424228). Methods: Adults with chronic constipation and ≤2 spontaneous complete bowel movements (SCBMs)/week were randomized to receive prucalopride 2 mg or placebo daily for 24 weeks. The primary endpoint was the proportion of patients achieving a mean of ≥3 SCBMs/week over the treatment period, assessed using daily e-diaries. Secondary outcomes and safety parameters were assessed throughout the study. Key Results: Overall, 361 patients were randomized and received prucalopride or placebo. Baseline characteristics were similar in the prucalopride (N = 181) and placebo (N = 180) groups. Mean age was 48.9 years (standard deviation, 16.0) and most patients were women. The proportion of participants achieving the primary endpoint was not statistically different between the prucalopride and placebo groups (25.1% vs 20.7%; p = 0.367). There was also no statistically significant difference between groups over the first 12-week period (prucalopride, 25.1%; placebo, 20.1%; p = 0.341). There were no statistically significant differences between groups for most secondary endpoints. No new safety concerns were identified. Conclusions & Inferences: This trial did not show statistically significant improvements in primary or secondary outcomes with prucalopride compared with placebo over 24 or 12 weeks. This is in contrast to the results of four previous 12-week trials, which demonstrated prucalopride to be significantly more effective than placebo. An extensive evaluation did not provide an explanation for the null efficacy results of this study. © 2015 The Authors. Neurogastroenterology & Motility published by John Wiley & Sons Ltd.

Survey of transfusion practices in preterm infants in Europe
- 2023
-
In: Archives of disease in childhood. Fetal and neonatal edition. - : BMJ. - 1468-2052 .- 1359-2998. ; 108:4, s. 360-366

Journal article (peer-reviewed)abstract
- Preterm infants commonly receive red blood cell (RBC), platelet and fresh frozen plasma (FFP) transfusions. The aim of this Neonatal Transfusion Network survey was to describe current transfusion practices in Europe and to compare our findings to three recent randomised controlled trials to understand how clinical practice relates to the trial data.MethodsFrom October to December 2020, we performed an online survey among 597 neonatal intensive care units (NICUs) caring for infants with a gestational age (GA) of <32 weeks in 18 European countries.ResultsResponses from 343 NICUs (response rate: 57%) are presented and showed substantial variation in clinical practice. For RBC transfusions, 70% of NICUs transfused at thresholds above the restrictive thresholds tested in the recent trials and 22% below the restrictive thresholds. For platelet transfusions, 57% of NICUs transfused at platelet count thresholds above 25×109/L in non-bleeding infants of GA of <28 weeks, while the 25×109/L threshold was associated with a lower risk of harm in a recent trial. FFP transfusions were administered for coagulopathy without active bleeding in 39% and for hypotension in 25% of NICUs. Transfusion volume, duration and rate varied by factors up to several folds between NICUs.ConclusionsTransfusion thresholds and aspects of administration vary widely across European NICUs. In general, transfusion thresholds used tend to be more liberal compared with data from recent trials supporting the use of more restrictive thresholds. Further research is needed to identify the barriers and enablers to incorporation of recent trial findings into neonatal transfusion practice.
