Profiling Tissue and Biofluid miR-155-5p, miR-155, and miR-146a-5p Expression in Graft vs. Host Disease.

Acute graft vs. host disease (aGvHD) is a frequent complication following allogeneic haematopoeitic transplantation (HSCT). Despite recent advances, there are no universally accepted biomarkers to determine development of aGvHD.

Management of compromised first permanent molars in children: Cross-Sectional analysis of attitudes of UK general dental practitioners and specialists in paediatric dentistry.

Background: It is unclear on how children with compromised first permanent molars (cFPMs) are currently managed in the UK by either general dental practitioners (GDP) or specialists in paediatric dentistry (SPD).

Aim: Explore the current attitudes to the management of compromised first permanent molars amongst UK general dental practitioners and specialists in paediatric dentistry.

Design: Self-completed online questionnaire including three clinical vignettes of 7, 9, and 15 years old with cFPM.

The influence of glucocorticoid receptor single nucleotide polymorphisms on outcome after haematopoietic stem cell transplantation.

Haematopoietic stem cell transplantation (HSCT) remains the only cure for most haematological malignancies, however, the mortality rate remains high. Complications after HSCT include relapse, graft versus host disease (GvHD), graft rejection and infection. Over the last few years several groups, have demonstrated that non-HLA gene polymorphisms can be predictive of outcome after HSCT.

Differential MicroRNA Expression Levels in Cutaneous Acute Graft-Versus-Host Disease.

Allogeneic hematopoietic stem cell transplantation is a curative treatment for numerous hematological malignancies. However, acute graft-versus-host disease (aGvHD) is a major complication affecting 40-70% of all transplant patients, whereby the earliest and most frequent presentation is in the skin. MicroRNAs play a role in varied biological process and have been reported as potential biomarkers for aGvHD.

Monitoring of Antiplatelet Therapy in Children on Ventricular Assist Device Support: Comparison of Multiplate and Thromboelastography Platelet Mapping.

The optimal method for monitoring antiplatelet therapy in children supported with ventricular assist devices (VADs) is unknown. We conducted a retrospective study to compare Thromboelastography Platelet Mapping (TEG/PM) with multiple electrode platelet aggregometry (MEA) on a Multiplate analyzer (Roche Diagnostics, Mannheim, Germany). We analyzed data from 66 paired blood samples from 9 patients <16 years of age on VAD where platelet function was simultaneously measured with TEG/PM and MEA.

Serum and Extracellular Vesicle MicroRNAs miR-423, miR-199, and miR-93* As Biomarkers for Acute Graft-versus-Host Disease.

Acute graft-versus-host disease (aGvHD) is a major cause of adverse outcome in hematopoietic stem cell transplantation (HSCT), with a high incidence (20-50%). A novel, non-invasive diagnostic test to predict for prevalence and severity would enable improved prophylaxis and reduce morbidity. Circulatory microRNAs (miRNAs) miR-423, miR-199, miR-93*, and miR-377 have previously been associated with aGvHD in post-HSCT patient plasma, but validation is lacking and their expression within extracellular vesicles (EVs) has not been explored.

Expression of Serum microRNAs is Altered During Acute Graft-versus-Host Disease.

Acute graft-versus-host disease (aGvHD) is the most frequent and serious complication following hematopoietic stem cell transplantation (HSCT), with a high mortality rate. A clearer understanding of the molecular pathogenesis may allow for improved therapeutic options or guide personalized prophylactic protocols. Circulating microRNAs are expressed in body fluids and have recently been associated with the etiology of aGvHD, but global expression profiling in a HSCT setting is lacking.

miR-146a and miR-155 Expression Levels in Acute Graft-Versus-Host Disease Incidence.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a curative treatment for numerous hematological malignancies. However, acute graft-versus-host disease (aGVHD) is still the major complication causing mortality. MicroRNAs (miRNAs) play a significant role in inflammation and have potential as prognostic and diagnostic biomarkers.

Elevated level of HSPA1L mRNA correlates with graft-versus-host disease.

Graft-versus-host disease (GVHD) can be a fatal complication of allogeneic stem cell transplantation (allo-HSCT). GVHD can be classified as acute (aGVHD: up to 100 days) or chronic (cGVHD: after 100 days) based on the time-point of disease occurrence. At present there are a limited number of biomarkers available for use in the clinic.

Regulation of advanced therapy medicinal products in Europe and the role of academia.

Background Aims: Advanced therapy medicinal products (ATMP) are gene therapy, somatic cell therapy or tissue-engineered products regulated under (EC) No. 1394/2007 to ensure their free movement within the European Union while guaranteeing the highest level of health protection for patients. Academic good manufacturing practice (GMP) centers are major contributors in the development of ATMPs and this study assessed the impact of regulations on them.

Analysis of non-HLA genomic risk factors in HLA-matched unrelated donor hematopoietic cell transplantation for chronic myeloid leukemia.

Background: Allogeneic hematopoietic cell transplantation is the main curative therapy for patients with chronic myeloid leukemia who do not respond to tyrosine kinase inhibitors. It has been proposed that non-human leukocyte antigen gene polymorphisms influence outcome after hematopoietic cell transplantation and could be used alongside traditional patient-donor and transplant characteristics to create a recipient risk profile associated with allogeneic hematopoietic cell transplantation.

Design And Methods: A previous study from the European Group for Blood and Marrow Transplantation showed that the absence of recipient tumor necrosis factor receptor II, absence of donor interleukin 10 ATA/ACC and presence of donor interleukin 1 receptor antagonist allele 2 genotypes were associated with decreased survival and increased non-relapse mortality in adult patients with chronic myeloid leukemia undergoing myeloablative human leukocyte antigen-identical sibling transplantation.

Impact of genomic risk factors on outcome after hematopoietic stem cell transplantation for patients with chronic myeloid leukemia.

Background: Non-HLA gene polymorphisms have been shown to influence outcome after allogeneic hematopoietic stem cell transplantation. Results were derived from heterogeneous, small populations and their value remains a matter of debate.

Design And Methods: In this study, we assessed the effect of single nucleotide polymorphisms in genes for interleukin 1 receptor antagonist (IL1RN), interleukin 4 (IL4), interleukin 6 (IL6), interleukin 10 (IL10), interferon (IFNG), tumor necrosis factor (TNF) and the cell surface receptors tumor necrosis factor receptor II (TNFRSFIB), vitamin D receptor (VDR) and estrogen receptor alpha (ESR1) in a homogeneous cohort of 228 HLA identical sibling transplants for chronic myeloid leukemia.
