Quality of life (QOL) and symptom burden are important measures captured by patient-reported outcomes (PROs). Myelodysplastic and myelodysplastic/myeloproliferative (MDS/MPN) neoplasm overlap syndromes are notable for significant morbidity and mortality, including a wide spectrum of physical and psychosocial effects. Thus, the development and application of PROs can provide meaningful information to facilitate communication and assist in follow up care. Disease-specific measures can more accurately reflect the full breadth of functional restrictions and symptoms...

The ability to simultaneously detect JAK2 V617F and MPL W515K/L mutations would substantially improve the early diagnosis of myeloproliferative neoplasms (MPNs) and decrease the risk of arterial thrombosis. The goal of this study is to achieve a point of care testing platform for simultaneous analysis of major genetic alterations in MPN. Here, we report a microfluidic platform including a glass capillary containing polypropylene matrix that extracts genomic DNA from a drop of whole blood, a microchip for simultaneous multi-gene mutation screening, and a handheld battery-powered heating device...

Spatiotemporal interrogation of signal transduction at the single-cell level is necessary to answer a host of important biological questions. This protocol describes a nanotechnology-based single-cell and single-molecule perturbation tool, termed mechanogenetics, that enables precise spatial and mechanical control over genetically encoded cell-surface receptors in live cells. The key components of this tool are a magnetoplasmonic nanoparticle (MPN) actuator that delivers defined spatial and mechanical cues to receptors through target-specific one-to-one engagement and a micromagnetic tweezers (μMT) that remotely controls the magnitude of force exerted on a single MPN...

A unique compost called Satsuma soil is produced from sewage sludge by a hyperthermal composting process in Kagoshima City, Japan. The composting process is carried out at a controlled temperature of at least 80°C and the resulting compost might be useful for recycling sustainable agricultural products. The extremely thermophilic bacterial genus Calditerricola was initially isolated from the high-temperature compost. Likewise, the bacteria were previously isolated from material sludge. It is believed that bacteria in this genus might be involved in the hyperthermal composting process...

There is evidence of continuous bidirectional cross-talk between malignant cells and bone marrow-derived mesenchymal stromal cells (BM-MSC), which favors the emergence and progression of myeloproliferative neoplastic (MPN) diseases. In the current work we have compared the function and gene expression profile of BM-MSC from healthy donors (HD-MSC) and patients with MPN (JAK2V617F), showing no differences in the morphology, proliferation and differentiation capacity between both groups. However, BM-MSC from MPN expressed higher mean fluorescence intensity (MIF) of CD73, CD44 and CD90, whereas CD105 was lower when compared to controls...

The aim of this work was to evaluate the microbiological quality of striped venus clams (Chamelea gallina L.) harvested in the north Adriatic Sea during an 8-year monitoring period. A total of 387 samples were analyzed to assess the presence of Escherichia coli. Environmental parameters (salinity, pH, dissolved oxygen, seawater temperature, and freshwater outflow) were collected to find out a possible relationship between the E. coli counts and environmental factors. The results evidenced that the microbiological quality of the clams was good, with only about 5% of the samples not complying with European and Italian regulations for this product, that is, with E...

Myelofibrosis (MF), polycythemia vera (PV), and essential thrombocythemia (ET) are myeloproliferative neoplasms (MPNs) associated with high disease burden, reduced quality of life (QOL), and shortened survival. To assess how MPNs affect patients, we conducted a global MPN Landmark survey. This online survey of patients with MPNs and physicians was conducted in Australia, Canada, Germany, Japan, Italy, and the United Kingdom. The survey measured MPN-related symptoms and the impact of MPNs on QOL and the ability to work as well as disease-management strategies...

Myeloproliferative neoplasms (MPNs), including polycythemia vera and essential thrombocythemia, are frequently associated with thrombotic complications. Prevention of thrombotic events is thus a primary aim of the current treatment for these disorders. Although it is known that microparticles (MPs), which are small vesicles released from cell membranes and circulate in the blood, directly contribute to thrombosis via their procoagulant activity, potential associations between plasma levels of MPs and the risk of thrombotic events in MPNs have not been reported...

Radislav A Potyrailo
For detection of gases and vapors in complex backgrounds, "classic" analytical instruments are an unavoidable alternative to existing sensors. Recently a new generation of sensors, known as multivariable sensors, emerged with a fundamentally different perspective for sensing to eliminate limitations of existing sensors. In multivariable sensors, a sensing material is designed to have diverse responses to different gases and vapors and is coupled to a multivariable transducer that provides independent outputs to recognize these diverse responses...

Peptide Receptor Radionuclide Therapy (PRRT) may induce long-term toxicity to the bone marrow (BM). The aim of this study was to analyze persistent dysfunction of the hematopoietic system after PRRT with (177)Lu-DOTATATE in patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Methods: The incidence and course of persistent hematological dysfunction (PHD) was analyzed in 274 (=GEP-NET) out of 367 patients with somatostatin receptor-positive tumors. PHD was defined as diagnosis of Myelodysplastic Syndrome (MDS), Acute Myeloid Leukemia (AML), Myeloproliferative Neoplasms (MPN), Myelodysplastic/Myeloproliferative neoplasms (MDS/MPN) or otherwise unexplained cytopenia (for more than 6 months)...

BACKGROUND: Hypomethylating agents (HMAs) improve survival in patients with higher-risk myelodysplastic syndromes (MDS) but are less well-studied in lower-risk disease. We compared the safety and efficacy of low-dose decitabine versus low-dose azacitidine in this group of patients. METHODS: Adults with low- or intermediate-1-risk MDS or MDS/myeloproliferative neoplasm (MPN), including chronic myelomonocytic leukemia, by the International Prognostic Scoring System were randomized using a Bayesian adaptive design to receive either azacitidine 75 mg/m(2) IV/SC daily or decitabine 20 mg/m(2) IV daily for 3 consecutive days on a 28-day cycle...

Myelodysplastic and myeloproliferative neoplasms (MDS/MPN) is a rare and distinct group of myeloid neoplasms with overlapping MDS and MPN features. Next generation sequencing studies have led to an improved understanding of MDS/MPN disease biology by identifying recurrent somatic mutations. Combining the molecular findings to patho-morphologic features has improved the precision of diagnosis and prognostic models in MDS/MPN. We discuss and highlight these updates in MDS/MPN nomenclature and diagnostic criteria per revised 2016 WHO classification of myeloid neoplasms in this article...

Myelodysplastic syndromes/myeloproliferative neoplasms (MDS/MPN) comprise a spectrum of myeloid disorders with both dysplastic and proliferative features, arising from hematopoietic stem cells. MDS/MPN are neither MDS nor MPN but a distinct World Health Organization-defined subclassification of diseases that, by definition, do not arise from a pre-existing MDS or MPN, inherently creating diagnostic and therapeutic challenges. Appropriately recognizing and classifying MDS/MPN is paramount for appropriately formulating treatment strategies and accurate prognostication...

BACKGROUND: Myelofibrosis (MF) is the most aggressive Philadelphia-negative chronic myeloproliferative neoplasm (MPN) with high morbidity and mortality due to thrombo-hemorrhagic complications and leukemic transformation. MF is characterized by profound alterations of megakaryocytopoiesis, with consequent abnormalities in platelet number and function. We recently showed that the overexpression of the oncoprotein PKCepsilon plays a key role in the aberrant differentiation of MF megakaryocyte clone and that its levels correlate with disease burden...

Germline variations at JAK2, TERT, HBS1L-MYB and MECOM have been found to associate with myeloproliferative neoplasms (MPNs) in European populations. Whether these germline variations are associated with MPNs in Taiwanese population is obscure. Here we aimed to evaluate the association of five germline variations (JAK2 46/1 haplotype tagged by rs12343867, JAK2 intron 8 rs12339666, TERT rs2736100, HBS1L-MYB rs9376092 and MECOM rs2201862) and the risk of MPNs in Taiwanese population.

The multistep process of TP53 mutation expansion during myeloproliferative neoplasm (MPN) transformation into acute myeloid leukemia (AML) has been documented retrospectively. It is currently unknown how common TP53 mutations with low variant allele frequency (VAF) are, whether they are linked to hydroxyurea (HU) cytoreduction, and what disease progression risk they carry. Using ultra-deep next-generation sequencing, we examined 254 MPN patients treated with HU, interferon alpha-2a or anagrelide and 85 untreated patients...

The acquired kinase mutation JAK2V617F plays a central role in myeloproliferative neoplasms (MPNs). However, the mechanisms responsible for the malignant hematopoietic stem/progenitor cell (HSPC) expansion seen in patients with MPNs are not fully understood, limiting the effectiveness of current treatment. Endothelial cells (ECs) are an essential component of the hematopoietic niche, and they have been shown to express the JAK2V617F mutation in patients with MPNs. We show that the JAK2V617F-bearing vascular niche promotes the expansion of the JAK2V617F HSPCs in preference to JAK2WT HSPCs, potentially contributing to poor donor cell engraftment and disease relapse following stem cell transplantation...
