The promotion of care for female victims of violence implies action that is not limited to combatting the problem, but also to the dimension of care provided to the victims. This study seeks to understand the sociodemographic and health characteristics of female victims of violence who are/have been under the protective custody of the state, before and after the Maria da Penha Law (MPL), and the healthcare offered to them. It is a cross-sectional, exploratory-descriptive documentary study, with a qualitative/quantitative approach, conducted in the second semester of 2013 in a special unit for the protection of female victims of violence in the State of Ceará...

The last decade has witnessed tremendous scientific advances, ushered in by the JAK2 V617F discovery, contributing to enhanced diagnostic capability and understanding of the biology of myeloproliferative neoplasms (MPNs). Discovery of the calreticulin mutations filled a diagnostic gap; more recent work sheds light on its contribution to disease pathogenesis, and prognosis. Recent studies have also identified novel JAK2 and MPL mutations in patients with essential thrombocythemia and myelofibrosis (MF). Especially in MF, the driver mutational profile has prognostic implications, with additive contributions from the acquisition of additional somatic mutations...

The 2016 multiparameter World Health Organization (WHO) classification for Philadelphia-negative myeloproliferative neoplasms (MPNs) integrates clinical features, morphology, and genetic data to diagnose polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF). The main novelties are: (1) the reduction of the hemoglobin (Hb) level threshold to diagnose PV, now established at 16.5 g/dL for men and 16 g/dL for women (based on the identification of MPN patients with PV-consistent bone marrow [BM] features and a Hb level lower than that established in the 2008 WHO classification for PV); (2) the recognition of prefibrotic/early PMF, distinguishable from ET on the basis of BM morphology, an entity having a higher tendency to develop overt myelofibrosis or acute leukemia, and characterized by inferior survival; (3) the central role of BM morphology in the diagnosis of ET, prefibrotic/early PMF, PMF, and PV with borderline Hb values; megakaryocyte number and morphology (typical in ET, atypical in both PMF forms) accompanied by a new distinction of reticulin fibrosis grade in PMF (grade 1 in prefibrotic/early PMF and grade 2-3 in PMF) constitute diagnostic criteria; and (4) the inclusion of all mutually exclusive MPN driver mutations (JAK2, CALR, and MPL) as major diagnostic criteria in ET and PMF; 10% to 15% of these patients are triple negative, and in these cases the search for an additional clonal marker (eg, mutations in ASXL1, EZH2, TET2, IDH1/IDH2, SRSF2, and SF3B1) is warranted...

Background: The discovery of somatic acquired mutations of JAK2 (V617F) in Philadelphia-negative myeloproliferative neoplasms (Ph-negative MPNs) including polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF) has not only improved rational disease classification and prognostication but also brings new understanding insight into the pathogenesis of diseases. Dosage effects of the JAK2 (V617F) allelic burden in Ph-negative MPNs may partially influence clinical presentation, disease progression, and treatment outcome...

Vaccine adjuvant effects in the CD4-deficient condition largely remain unknown. We investigated the roles of combined monophosphoryl lipid A (MPL) and aluminum hydroxide (Alum) adjuvant (MPL+Alum) in inducing immunity after immunization of CD4 knockout (CD4KO) and wild-type (WT) mice with T-dependent influenza vaccine. MPL+Alum adjuvant mediated IgG isotype-switched Abs, IgG-secreting cell responses, and protection in CD4KO mice, which were comparable to those in WT mice. In contrast, Alum adjuvant effects were dependent on CD4(+) T cells...

The myeloproliferative neoplasms (MPNs) are characterized by hematopoietic stem/progenitor cell (HSPC) expansion and overproduction of blood cells. The acquired mutation JAK2(V617F) plays a central role in these disorders. Mechanisms responsible for MPN HSPC expansion is not fully understood, limiting the effectiveness of current treatments. Endothelial cells (ECs) carrying the JAK2(V617F) mutation can be detected in patients with MPNs, suggesting that ECs are involved in the pathogenesis of MPNs. Here we report that JAK2(V617F)-bearing primary murine ECs have increased cell proliferation and angiogenesis in vitro compared to JAK2(WT) ECs...

Myeloproliferative neoplasms are clonal hematopoietic stem cell disorders characterized by aberrant proliferation and an increased tendency toward leukemic transformation. The genes JAK2, MPL, and CALR are frequently altered in these syndromes, and their mutations are often a strong argument for diagnosis. We analyzed the mutational profiles of these three genes in a cohort of 164 suspected myeloproliferative neoplasms. JAK2 V617F mutation was detected by real-time PCR, whereas high-resolution melting analysis followed by Sanger sequencing were used for searching for mutations in JAK2 exon 12, CALR, and MPL...

To investigate immuno-chemotherapy for elderly immuno-competent patients (⩾65 years) with newly diagnosed primary central nervous system lymphoma (PCNSL), we conducted a multicentre single arm trial. One cycle consisted of rituximab (375 mg/m(2), day 1, 15, 29), high-dose methotrexate (3 g/m(2) days 2, 16, 30), procarbazine (60 mg/m(2) day 2-11), and lomustine (110 mg/m(2), day 2)-R-MPL protocol. Due to infectious complications we omitted lomustine during the study and consecutive patients were treated with the R-MP protocol...

Autoimmune myelofibrosis is a rare, distinct clinicopathological entity that can occur in isolation (primary) or in association with systemic autoimmune disorders (secondary), such as systemic lupus erythematosus and Sjogren's syndrome. This disease is characterized by isolated or combined chronic cytopenias associated with autoimmune phenomena and bone-marrow fibrosis. Due to the rarity of this disease, patients are frequently misdiagnosed as having primary myelofibrosis, the most common form of bone-marrow fibrosis...

BACKGROUND: Thrombopoietin-receptor-agonists (TPO-RAs) increase platelet production in Immune Thrombocytopenia (ITP) by stimulating Mpl. The effect of TPO-RAs on inflammatory cytokine production in ITP patients has not been well investigated. METHODS: Plasma samples from 48 ITP patients treated with TPO-RAs (median age 50 years (inter-quartile range; IQR 20-69), median platelet counts 24 × 10(9)/L (IQR 15-47 × 10(9)/L), 28 females) and 16 healthy controls (nine females, median age 37 years, IQR 22-51 years) were collected before and during treatment, and analyzed for a panel of cytokines and chemokines by enzyme-linked immunosorbent assay and immuno-bead-based multiplex assay...

Mutations in the human myeloproliferative leukemia protein gene (MPL) are known to cause congenital amegakaryocytic thrombocytopenia (CAMT). The prognosis of this heritable disorder is poor and bone marrow transplantation is the only effective treatment. Here, by using transcription activator-like effect or nucleases (TALEN) technology, we created a zebrafish mpl mutant to model human CAMT. Disruption of zebrafish mpl leaded to a severe reduction in thrombocytes and a high bleeding tendency, as well as deficiencies in adult HSPCs...

Mutations of calreticulin (CALR) are detected in 25-30% of patients with essential thrombocythemia (ET) or primary myelofibrosis and cause frameshifts that result in proteins with a novel C-terminal. We demonstrate that CALR mutations activated signal transducer and activator of transcription 5 (STAT5) in 293T cells in the presence of thrombopoietin receptor (MPL). Human megakaryocytic CMK11-5 cells and erythroleukemic F-36P-MPL cells with knocked-in CALR mutations showed increased growth and acquisition of cytokine-independent growth, respectively, accompanied by STAT5 phosphorylation...

A study published in 2007 showed that the intake of six food colours (the so-called 'Southampton colours') may have an adverse effect on activity and attention in children. The present study set out to assess the exposure of Polish children (3 and 8-9 years old, n = 149) to six of the target colours. Two methods were used to evaluate colour consumption by children: scenario 1 using the maximum permitted levels (MPLs) and actual food consumption data; and scenario 2 using the actual levels in food and actual food consumption data...

The current therapeutic strategy for multiple myeloma has improved dramatically due to the use of novel agents. In newly diagnosed transplant-ineligible myeloma patients, the standard therapy until the 1990s had long been melphalan and prednisolone (MP), but the recent recommendation is the proteasome inhibitor bortezomib plus MP (MPB), the immunomodulatory drug thalidomide plus MP (MPT), and the thalidomide derivative lenalidomide (LEN)-based regimens such as LEN plus low-dose dexamethasone (Ld) and LEN plus MP (MPL)...

Thrombopoietin was posited to exist in 1958 and cloned in 1994, and in the ensuing two decades we have learned a great deal about the physiology and pathology of the primary regulator of thrombopoiesis. This paper will review the role of the hormone and its receptor, the product of the c-Mpl proto-oncogene, in health and disease, including many unexpected effects in both normal and neoplastic hematopoiesis. Amongst these unexpected properties are a non-redundant effect on hematopoietic stem cells, a critical role in all three of the acquired, chronic myeloproliferative neoplasms, as well as both gain-of-function and loss-of-function mutations in congenital and acquired states of thrombocytopenia and thrombocythemia...

Approximately 70% of kidney transplant recipients are non-responders to conventional hepatitis B virus (HBV) vaccines. We examined whether Fendrix(™) , an HBV vaccine containing 3-O-desacyl-4'-monophosphoryl lipid A (MPL) as adjuvant, could induce HBV immunity in these patients and compared their vaccination efficacy with healthy controls tested previously by the same assays. We selected 35 kidney transplant recipients who had been vaccinated at least thrice against HBV but had never displayed anti-HBs antibodies...

Most myeloproliferative neoplasm (MPN) patients lacking JAK2 mutations harbour somatic CALR mutations that are thought to activate cytokine signalling although the mechanism is unclear. To identify kinases important for survival of CALR-mutant cells, we developed a novel strategy (KISMET) that utilizes the full range of kinase selectivity data available from each inhibitor and thus takes advantage of off-target noise that limits conventional small-interfering RNA or inhibitor screens. KISMET successfully identified known essential kinases in haematopoietic and non-haematopoietic cell lines and identified the mitogen activated protein kinase (MAPK) pathway as required for growth of the CALR-mutated MARIMO cells...
