    The chronic myeloproliferative diseases (CMDs) are a group of conditions characterized by unregulated blood cell production, that due either to excessive numbers of erythrocytes, leukocytes or platelets, or their defective function cause symptoms and signs of fatigue, headache, ruddy cyanosis, hemorrhage, abdominal distension, and the complications of vascular thrombosis. In the late 19th century Vaquez provided the first description of polycythemia vera (PV) and Hueck defined idiopathic myel...

    Chronic myeloproliferative disorders (cMPDs) are clonal hemopoietic malignancies arising at the multipotent stem cell level. These conditions are characterized by increased blood count, marrow hyperplasia and extramedulary hemopoiesis. Vascular events might complicate their course, and transformation to either acute leukemia or myelofibrosis can finally occur. Among cMPDs, Polycythemia Vera (PV), Essential Thrombocythemia (ET) and Primary Myelofibrosis (PMF) belong to the group of Ph-negative cMPDs. Although they share common pathogenetic features, these entities have a quite different prognosis. The common pathogenetic basis of Ph-negative cMPDs was recognized long ago, and it was suggested that a stimulating factor might enhance bone marrow hemopoietic activity. Hemopoietic progenitors from cMPDs show hypersensitivity to low levels of a variety of hemopoietic cytokines. The independency of erythroid precursors from erythropoietin became the first surrogate marker of an abnormal hemopoietic clone. This clone is characterized by increased proliferation and survival, as well as by decreased apoptosis, leading to the accumulation of mature blood cells that additionally show a phenotype of activated cells. Recently four independent groups have described an activating point mutation in the JAK2 kinase as a key pathogenetic event in Ph-negative cMPDs. JAK2 is a tyrosine kinase that acts as a second intracellular messenger for many hemopoietic cytokine receptors. It is now believed that jacking up hemopoiesis can explain many features of myeloproliferation. Interestingly, some features are associated with intracellular levels of mutated JAK2 (the "dosage hypothesis"). The mutation in JAK2 kinase is not an example of a genetic defect leading to a single disease, since it occurs in many other myeloid disorders, and probably represents a secondary hit in a multistep ongogenetic process. Nevertheless, it has changed the way we approach cMPD patients and has clarified many

    Myeloproliferative disorders (MPDs) constitute a group of hematopoietic malignancies that feature enhanced proliferation and survival of one or more myeloid lineage cells. William Dameshek is credited for introducing the term "MPDs" in 1951 when he used it to group chronic myeloid leukemia (CML), polycythemia vera (PV), essential thrombocythemia (ET) and primary myelofibrosis (PMF) under one clinicopathologic category. Since then, other myeloid neoplasms have been added to the MPD member list: chronic neutrophilic (CNL), eosinophilic (CEL) and myelomonocytic (CMML) leukemias; juvenile myelomonocytic leukemia (JMML); hypereosinophilic syndrome (HES); systemic mastocytosis (SM); and others. Collectively, MPDs are stem cell-derived clonal proliferative diseases whose shared and diverse phenotypic characteristics can be attributed to dysregulated signal transduction--a consequence of acquired somatic mutations. The most recognized among the latter is BCR-ABL, the disease-causing mutation in CML. Other mutations of putative pathogenetic relevance in MPDs include: JAK2V617F in PV, ET, and PMF; JAK2 exon 12 mutations in PV; MPLW515L/K in PMF and ET; KITD816V in SM; FIP1L1-PDGFRA in CEL-SM; rearrangements of PDGFRB in CEL-CMML and FGFR1 in stem cell leukemia-lymphoma syndrome; and RAS/PTPN11/NF1 mutations in JMML. This increasing repertoire of mutant molecules has streamlined translational research and molecularly targeted drug development in MPDs.

    Objective: We aimed to investigate the frequency of Janus kinase 2 (JAK2) mutations in cases with chronic myeloproliferative disorders (CMDs), and the relationship between the presence of JAK2 mutation and leukocytosis and splenomegaly, retrospectively. Materials and Methods: Patients, who were diagnosed with BCR-ABL-negative CMDs according to diagnosis criteria of the World Health Organization and followed up at the hematology clinic between 2013 and 2015, were investigated in terms of the frequency of JAK2 mutation in cases with CMDs, and the relationship between the presence of JAK2 mutation and leukocytosis and splenomegaly, retrospectively. Results: In total, 100 patients, who were diagnosed with BCR-ABL-negative CMDs, were evaluated retrospectively. The mean age of the patients with JAK2 positivity was significantly higher compared to patients with negative. JAK2-positivity rates in the age groups were significantly different. Gender, diagnosis, splenomegaly, and leukocytosis were not statistically different for JAK2 positivity between the groups. Conclusion: JAK2 V617F mutation is more commonly seen in older age as a risk for complications related to CDMS. Splenomegaly and leukocytosis are not associated with JAK2 V617F mutation.

    Full Text Available Chronic myeloproliferative diseases without the Philadelphia chromosome marker (Ph-, although first described 60 years ago, only became the subject of interest after the turn of the millennium. In 2001, the World Health Organization (WHO defined the classification of this group of diseases and in 2008 they were renamed myeloproliferative neoplasms based on morphological, cytogenetic and molecular features. In 2005, the identification of a recurrent molecular abnormality characterized by a gain of function with a mutation in the gene encoding Janus kinase 2 (JAK2 paved the way for greater knowledge of the pathophysiology of myeloproliferative neoplasms. The JAK2 mutation is found in 90-98% of polycythemia vera and in about 50% essential thrombocytosis and primary myelofibrosis. In addition to the JAK2 mutation, other mutations involving TET2 (ten-eleven translocation, LNK (a membrane-bound adaptor protein; IDH1/2 (isocitrate dehydrogenase 1/2 enzyme; ASXL1 (additional sex combs-like 1 genes were found in myeloproliferative neoplasms thus showing the importance of identifying molecular genetic alterations to confirm diagnosis, guide treatment and improve our understanding of the biology of these diseases. Currently, polycythemia vera, essential thrombocytosis, myelofibrosis, chronic neutrophilic leukemia, chronic eosinophilic leukemia and mastocytosis are included in this group of myeloproliferative neoplasms, but are considered different situations with individualized diagnostic methods and treatment. This review updates pathogenic aspects, molecular genetic alterations, the fundamental criteria for diagnosis and the best approach for each of these entities.

    The temperature dependence of the apparent water diffusional exchange through erythrocyte membranes in cases of policitemia vera, chronic granulocytic leukemia and primary myelofibrosis was measured by using a nuclear magnetic resonance method in the presence of Mn2+. The thermal transition shifted to lower temperatures in all cases, regardless of the stage of the disease, suggesting a structural alteration of the membrane. The shift of transition indirectly suggests a lower penetration of the erythrocytes by Mn2+. The water exchange time at 37 degrees C also increased, mainly in the blast crisis; it seems to have a prognostic value of some clinical interest. No simple correlation of the water exchange and the following clinical investigations was observed: the white count, the percentage of promyelocites and myeloblasts, the sedimentation rate of blood, the osmotic fragility of erythrocytes, the total concentration of proteins, albumin and immunoglobulins, respectively, in plasma.

    HSCT have been restricted as a result of mortality related to this procedure and imatinib mesylate has become the new treatment of choice for this disease. In Brazil and possibly in other developing countries, socio-economic conditions make HSCT still feasible as first-line treatment in some situations. The HSCT remains indicated for Ph negative myeloproliferative disorders such as high risk myelofibrosis or patients with polycythemia vera or essential thrombocytosis that have evolved to myelofibrosis with high-risk features.

  15. The genetic basis of myeloproliferative disorders.

    For many decades, myeloproliferative disorders (MPD) were largely neglected orphan diseases. The conceptual work of William Dameshek in 1951 provided the basis for understanding MPD as a continuum of related syndromes, possibly with a common pathogenetic cause. Recognition of the clonal origin of peripheral blood cells in MPD in 1976 and the ability to grow erythroid colonies in vitro in the absence of added growth factors in 1974 initiated the search for genetic alterations that might be responsible for myeloproliferation. Mutations in the genes for the erythropoietin receptor, thrombopoietin and the von Hippel-Lindau protein were found to cause familial syndromes resembling MPD, but despite their phenotypic similarities, none of these mutations were later found in patients with the sporadic form of MPD. The discovery of activating mutations in the Janus kinase 2 (JAK2) in most patients with MPD has fully transformed and energized the MPD field. Sensitive assays for detecting the JAK2-V617F mutation have become an essential part of the diagnostic work-up, and JAK2 now constitutes a prime target for developing specific inhibitors for the treatment of patients with MPD. Despite this progress, many questions remain unsolved, including how a single JAK2 mutation causes three different MPD phenotypes, what other genes might be involved in the pathogenesis, and what are the factors determining the progression to acute leukemia.

    2015-01-01

    Myeloproliferative neoplasms (MPNs) are a heterogeneous group of clonal diseases characterized by the excessive and chronic production of mature cells from one or several of the myeloid lineages. Recent advances in the biology of MPNs have greatly facilitated their molecular diagnosis since most patients present with mutation(s) in the JAK2, MPL, or CALR genes. Yet the roles played by these mutations in the pathogenesis and main complications of the different subtypes of MPNs are not fully elucidated. Importantly, chronic inflammation has long been associated with MPN disease and some of the symptoms and complications can be linked to inflammation. Moreover, the JAK inhibitor clinical trials showed that the reduction of symptoms linked to inflammation was beneficial to patients even in the absence of significant decrease in the JAK2-V617F mutant load. These observations suggested that part of the inflammation observed in patients with JAK2-mutated MPNs may not be the consequence of JAK2 mutation. The aim of this paper is to review the different aspects of inflammation in MPNs, the molecular mechanisms involved, the role of specific genetic defects, and the evidence that increased production of certain cytokines depends or not on MPN-associated mutations, and to discuss possible nongenetic causes of inflammation.

    Myeloproliferative neoplasms (MPNs) are clonal disorders of hematopoiesis characterized by a high frequency of genetic alterations and include chronic myeloid leukemia (CML) and the BCR-ABL1-negative MPNs. Herein we summarize recent advances and controversies in our understanding of the biology and therapy of these disorders, as discussed at the 8th post-American Society of Hematology CML-MPN workshop. The principal areas addressed include the breakthrough discovery of CALR mutations in patients with JAK2/MPL wild type MPN, candidate therapies based on novel genetic findings in leukemic transformation and new therapeutic targets in MPNs, and an appraisal of bone marrow histopathology in MPNs with a focus on the potential new clinical entity of “ masked ” polycythemia vera. An update on clinical trials of Janus kinase (JAK) inhibitors is presented as well as current understanding regarding the definitions and mechanisms of resistance to JAK inhibitors, and updated information on the safety and efficacy of discontinuation of tyrosine kinase inhibitors in patients with CML.

    Objective To investigate the clinical characteristics, the antenatal management, the outcome and prognosis of chronic myeloproliferative disorders (CMPD) complicating pregnancy. Methods Retrospectively analyze the clinical data of eleven patients with CMPD complicating pregnancy hospitalized in Peking University People' s Hospital from 2000 to 2009, including five patients with essential thrombocythemia, one with primary myelofibrosis and five with chronic myeloid leukemia. Results (1)Five pregnancies had periodic antenatal care and laboratory monitorings like full blood count. Reasonable anti-coagulation therapy was given to prevent the complications. One patient with PMF diagnosed before conception had her first pregnancy ended with mild pre-eclampsia and intrauterine death at the gestational age of 32 weeks. During the first trimester of her second pregnancy two years later, the test for anti-β2 glycoprotein antibody was positive. She received low-dose aspirin and low-molecular-weight heparin as anticoagulants. An uneventful course was obtained and she delivered a healthy term infant. (2) Five pregnancies had occasional antenatal examination, including two patients with ET and three patients with CML One patient with ET developed severe pre-eclampsia at the gestational age of 25 weeks. Umbilical artery Doppler showed reversed end-diastolic velocity. The management with anti-convulsants, antihypertensives and anti-coagulants showed no effect. An emergency cesarean section had to be performed because of the aggressive hypertension and placental abruption, with still birth as a result. Two pregnancies never had an antenatal care. Both of them were admitted on labor and the diagnoses of CML were made. (3)Four pregnancies developed oligohydramnios and three developed preelampsia(two severe pre-eclampsia and one mild pre-eclampsia). There was no other hemorrhage and thrombosis event.

    Full Text Available Violaine Havelange,1,2 Jean-Baptiste Demoulin1 1de Duve Institute, Université catholique de Louvain, Brussels, Belgium; 2Department of Hematology, Cliniques universitaires Saint-Luc, Université catholique de Louvain, Brussels, Belgium Abstract: Recent advances in our understanding of the molecular mechanisms underlying hypereosinophilia have led to the development of a 'molecular' classification of myeloproliferative disorders with eosinophilia. The revised 2008 World Health Organization classification of myeloid neoplasms included a new category called “myeloid and lymphoid neoplasms with eosinophilia and abnormalities of PDGFRA, PDGFRB or FGFR1.” Despite the molecular heterogeneity of PDGFR (platelet-derived growth factor receptor rearrangements, tyrosine kinase inhibitors at low dose induce rapid and complete hematological remission in the majority of these patients. Other kinase inhibitors are promising. Further discoveries of new molecular alterations will direct the development of new specific inhibitors. In this review, an update of the classifications of myeloproliferative disorders associated with hypereosinophilia is discussed together with open and controversial questions. Molecular mechanisms and promising results of tyrosine kinase inhibitor treatments are reviewed.

    Full Text Available Introduction This study describes the incidence and risk factors of de novo nephrolithiasis among patients with lymphoproliferative or myeloproliferative diseases who have undergone chemotherapy. Materials and Methods From 2001 to 2011, patients with lymphoproliferative or myeloproliferative disorders treated with chemotherapy were retrospectively identified. The incidence of image proven nephrolithiasis after chemotherapy was determined. Demographic and clinical variables were recorded. Patients with a history of nephrolithiasis prior to chemotherapy were excluded. The primary outcome was incidence of nephrolithiasis, and secondary outcomes were risk factors predictive of de novo stone. Comparative statistics were used to compare demographic and disease specific variables for patients who developed de novo stones versus those who did not. Results A total of 1,316 patients were identified and the incidence of de novo nephrolithiasis was 5.5% (72/1316; symptomatic stones 1.8% 24/1316. Among patients with nephrolithiasis, 72.2% had lymphoproliferative disorders, 27.8% had myeloproliferative disorders, and 25% utilized allopurinol. The median urinary pH was 5.5, and the mean serum uric acid, calcium, potassium and phosphorus levels were 7.5, 9.6, 4.3, and 3.8 mg/dL, respectively. In univariate analysis, mean uric acid (p=0.013, calcium (p<0.001, and potassium (p=0.039 levels were higher in stone formers. Diabetes mellitus (p<0.001, hypertension (p=0.003, and hyperlipidemia (p<0.001 were more common in stone formers. In multivariate analysis, diabetes mellitus, hyperuricemia, and hypercalcemia predicted stone. Conclusions We report the incidence of de novo nephrolithiasis in patients who have undergone chemotherapy. Diabetes mellitus, hyperuricemia, and hypercalcemia are patient-specific risk factors that increase the odds of developing an upper tract stone following chemotherapy.

  9. Mesenteric venous thrombosis secondary to an unsuspected JAK2 V617F-positive myeloproliferative disorder.

    LENUS (Irish Health Repository)

    2012-01-31

    BACKGROUND: Mesenteric venous thrombosis (MVT) is a rare but potentially fatal cause of mesenteric ischaemia. It presents insidiously and often diagnosis is made at emergency surgery. In half of the cases MVT develops without a causative factor, while in cases in which a pro-thrombotic state is found to exist MVT may be the first clinically detected consequence of that state. The myeloproliferative disorders (MPD) are known to contribute to the development of pro-thrombotic states. Recently, the JAK2 V617F mutation has been associated with the MPDs. CONCLUSION: We describe a case of MVT occurring secondary to an unsuspected MPD, in which the patient was subsequently found to carry this mutation. We highlight the necessity to screen for this mutation in cases of intra-abdominal thromboses so that appropriate systemic anticoagulation may be instituted, and the patient may be followed so as to detect the development of an overt MPD.

  10. The role of JAK1/2 inhibitors in the treatment of chronic myeloproliferative neoplasms.

    In 2005, the description of the JAK2V617F mutation for the first time provided a molecular key to enable more rapid diagnosis and target for novel therapeutics in the myeloproliferative neoplasms. In 2007, the first-in-class agent INC18424, ruxolitinib, JAKafi, or JAKAVI was first tested in patients with intermediate-risk 2 or high-risk myelofibrosis regardless of whether they possessed the JAK2V617F mutation. Patients treated with this agent had major reduction in splenomegaly as well as impressive reduction, and in some cases resolution, of symptoms. This study was followed by the two Controlled Myelofibrosis Study with Oral JAK Inhibitor Therapy (COMFORT) trials (the first-ever phase III trials in myelofibrosis), which confirmed results in these aspects were superior to either placebo or standard care, and updated results show a survival advantage with this therapy. This paper discusses these results and data from other JAK inhibitors while speculating on the future of these therapies. It also reflects on the fact that the true targets and agents' mode of action are uncertain. Unlike targeted therapy for chronic myeloid leukemia (CML), these agents do not deliver molecular remission, and it is not clear whether their predominant benefit is mediated via JAK2, JAK1, or both. Nonetheless, the advent of the JAK inhibitor is a welcome advance and has made a dramatic improvement to the therapeutic landscape of these conditions.

    The evidence that leukocytes may contribute to the pathogenesis of thrombosis in Chronic Myeloproliferative Neoplasms is increasing but not definitive. To further enforces whether an increased leukocyte count is associated with thrombosis and whether this effect can be modulated by cytoreductive therapy, we analyzed the clinical course of 187 patients with Polycythemia Vera (PV) and Essential Thrombocythemia (ET) followed at two Italian Institutions over a period of 7 years. The association was measured at diagnosis or before thrombotic events: a multivariable analysis was carried out using data at baseline and time-dependent covariates. We found that white blood cells (WBC) count above 9.5 x 10(9)/L at diagnosis (baseline analysis) was associated with thrombosis during the follow-up (Hazard Ratio [HR] of 1.8, p 0.03). At the time-dependent analysis, therapy with hydroxyurea (HU), lowering by 35% the baseline WBC level, reduced such strength of association giving a HR of 1.3 (p value non significant). We found a trend between WBC level and thrombosis in untreated low-risk patients (RR of 1.9, 95% CI 0.9 to 3.1); in high-risk patients treated with HU this correlation was clearly lost (RR 1.1, 95% CI 0.2 to 2.7). Finally, we could not identify the presence of JAK2 (V617F) as a risk factor for thrombosis. Properly designed prospective studies should corroborate such results.

    Although hydroxyurea is considered the first-line cytoreductive therapy in high-risk patients with polycythemia vera or essential thrombocythemia, approximately 20-25% of patients develop resistance or intolerance and they need an alternative therapy. Anagrelide is the treatment of choice in patients with essential thrombocythemia intolerant or with resistance to hydroxyurea. Anagrelide is usually well tolerated. Although there is concern about the increased risk of cardiac side effects, in most cases these are mild, and easily manageable. In this paper, the available evidence about the management of patients with myeloproliferative neoplasms, with a special focus on the side effects of drug therapies is reviewed.

    Pulmonary hypertension (PH) has emerged as a major complication of several hematologic disorders, including hemoglobinopathies, red cell membrane disorders, chronic myeloproliferative disorders, and splenectomy. With the exception of sickle cell disease, there are a limited number of studies systematically evaluating the prevalence of PH using the gold standard right heart catheterization in these disorders. The cause of the PH in patients with hematologic disorders is multifactorial, and a thorough diagnostic evaluation is essential. More importantly, there are virtually no high-quality data on the safety and efficacy of PH-targeted therapy in this patient population.

    Met is the receptor of hepatocyte growth factor (HGF), a cytoprotective cytokine. Disturbing the equilibrium between Met and its ligand may lead to inappropriate cell survival, accumulation of genetic abnormalities and eventually, malignancy. Abnormal activation of the HGF/Met axis is established in solid tumours and in chronic haematological malignancies, including myeloma, acute myeloid leukaemia, chronic myelogenous leukaemia (CML), and myeloproliferative neoplasms (MPNs). The molecular mechanisms potentially responsible for the abnormal activation of HGF/Met pathways are described and discussed. Importantly, inCML and in MPNs, the production of HGF is independent of Bcr-Abl and JAK2V617F, the main molecular markers of these diseases. In vitro studies showed that blocking HGF/Met function with neutralizing antibodies or Met inhibitors significantly impairs the growth of JAK2V617F-mutated cells. With personalised medicine and curative treatment in view, blocking activation of HGF/Met could be a useful addition in the treatment of CML and MPNs for those patients with high HGF/MET expression not controlled by current treatments (Bcr-Abl inhibitors in CML; phlebotomy, hydroxurea, JAK inhibitors in MPNs)

    Full Text Available Abstract. A role of intracellular proteins of eosinophils and mast cells remains unclear in the patients with hematological neoplasia. There is a substantial evidence that eosinophils possess some common mechanisms of cooperation with mast cells. Therapeutic interventions into key events controlling eosinophil migration may be a leading factor in treatment of hypereosinophylic states in onco-hematological disorders. Due to unknown functions of eosinophils in majority of eosinophilia-associated diseases, it would be useful to establish an algorithm of accurate diagnostics in the patients with eosinophilia, in order to choose more effective treatment in future.We studied serum levels of secretable eosinophil and mast cells proteins in oncohematological patients with increased eosinophil counts. The aim of our study was to test a significance of quantitative assay for tryptase and ECP in the patients with myelo- and lymphoproliferative diseases. The study group included thirty-eight patients with oncohematological diseases, accompanied by a marked eosinophilia (> 0.4 x 109/L. Eighteen patients with bronchial asthma (BA, and eight cases of solid tumors comprised a reference group for polyclonal eosinophilia. The levels of ECP and tryptase were measured in blood serum using a commercial fluoroimmunoenzyme assay («Pharmacia», Uppsala, Sweden. Total ECP levels were markedly increased in general group with hematological malignancies (p < 0.03, , and in cases of chronic GvHD (p < 0.03, and in a sub-group with lymphoproliferative disorders (р = 0.007 as compared to the group of non-hematological diseases.Serum levels of tryptase were significantly increased in the patients with chronic GvHD after allo-HSCT and lymphoproliferative diseases, as compared to the group of patients with solid tumors (р = 0.03, as well in GvHD compared with lymphoproliferative disorders (р < 0.05.A direct correlation was found between serum ECP levels and absolute

    Full Text Available Abstract Background The t(6;8 translocation found in rare and agressive myeloproliferative disorders results in a chimeric gene encoding the FOP-FGFR1 fusion protein. This protein comprises the N-terminal region of the centrosomal protein FOP and the tyrosine kinase of the FGFR1 receptor. FOP-FGFR1 is localized at the centrosome where it exerts a constitutive kinase activity. Results We show that FOP-FGFR1 interacts with the large centrosomal protein CAP350 and that CAP350 is necessary for FOP-FGFR1 localisation at centrosome. FOP-FGFR1 activates the phosphoinositide-3 kinase (PI3K pathway. We show that p85 interacts with tyrosine 475 of FOP-FGFR1, which is located in a YXXM consensus binding sequence for an SH2 domain of p85. This interaction is in part responsible for PI3K activation. Ba/F3 cells that express FOP-FGFR1 mutated at tyrosine 475 have reduced proliferative ability. Treatment with PI3K pathway inhibitors induces death of FOP-FGFR1 expressing cells. FOP-FGFR1 also recruits phospholipase Cγ1 (PLCγ1 at the centrosome. We show that this enzyme is recruited by FOP-FGFR1 at the centrosome during interphase. Conclusion These results delineate a particular type of oncogenic mechanism by which an ectopic kinase recruits its substrates at the centrosome whence unappropriate signaling induces continuous cell growth and MPD.

    Arginase (ARG) is a metabolic enzyme present in two isoforms that hydrolyze l-arginine to urea and ornithine. In humans, ARG isoform 1 is also expressed in cells of the myeloid lineage. ARG activity promotes tumour growth and inhibits T lymphocyte activation. However, the two ARG transgenic mouse lines produced so far failed to show such effects. We have generated, in two different genetic backgrounds, transgenic mice constitutively expressing ARG1 under the control of the CD68 promoter in macrophages and monocytes. Both heterozygous and homozygous transgenic mice showed a relevant increase in mortality at early age, compared with wild-type siblings (67/267 and 48/181 versus 8/149, respectively, both P < 0.005). This increase was due to high incidence of haematologic malignancies, in particular myeloid leukaemia, myeloid dysplasia, lymphomas and disseminated intravascular coagulation (DIC), diseases that were absent in wild-type mice. Atrophy of lymphoid organs due to reduction in T-cell compartment was also detected. Our results indicate that ARG activity may participate in the pathogenesis of lymphoproliferative and myeloproliferative disorders, suggest the involvement of alterations of L-arginine metabolism in the onset of DIC and confirm a role for the enzyme in regulating T-cell homeostasis.

  5. Atopic dermatitis-like disease and associated lethal myeloproliferative disorder arise from loss of Notch signaling in the murine skin.

    Directory of Open Access Journals (Sweden)

    Alexis Dumortier

    Full Text Available BACKGROUND: The Notch pathway is essential for proper epidermal differentiation during embryonic skin development. Moreover, skin specific loss of Notch signaling in the embryo results in skin barrier defects accompanied by a B-lymphoproliferative disease. However, much less is known about the consequences of loss of Notch signaling after birth. METHODOLOGY AND PRINCIPAL FINDINGS: To study the function of Notch signaling in the skin of adult mice, we made use of a series of conditional gene targeted mice that allow inactivation of several components of the Notch signaling pathway specifically in the skin. We demonstrate that skin-specific inactivation of Notch1 and Notch2 simultaneously, or RBP-J, induces the development of a severe form of atopic dermatitis (AD, characterized by acanthosis, spongiosis and hyperkeratosis, as well as a massive dermal infiltration of eosinophils and mast cells. Likewise, patients suffering from AD, but not psoriasis or lichen planus, have a marked reduction of Notch receptor expression in the skin. Loss of Notch in keratinocytes induces the production of thymic stromal lymphopoietin (TSLP, a cytokine deeply implicated in the pathogenesis of AD. The AD-like associated inflammation is accompanied by a myeloproliferative disorder (MPD characterized by an increase in immature myeloid populations in the bone marrow and spleen. Transplantation studies revealed that the MPD is cell non-autonomous and caused by dramatic microenvironmental alterations. Genetic studies demontrated that G-CSF mediates the MPD as well as changes in the bone marrow microenvironment leading to osteopenia. SIGNIFICANCE: Our data demonstrate a critical role for Notch in repressing TSLP production in keratinocytes, thereby maintaining integrity of the skin and the hematopoietic system.

    Liver fibrosis is one of the common complications of transient myeloproliferative disorder (TMD) in Down syndrome (DS), but the exact molecular pathogenesis is largely unknown. We herein report a neonate of DS with liver fibrosis associated with TMD, in which we performed the serial profibrogenic cytokines analyses. We found the active monocyte chemoattractant protein-1 expression in the affected liver tissue and also found that both serum and urinary monocyte chemoattractant protein-1 concentrations are noninvasive biomarkers of liver fibrosis. We also showed a prospective of the future anticytokine therapy with herbal medicine for the liver fibrosis associated with TMD in DS.

    Myeloproliferative disorders, a complex of cytologic abnormalities arising in the bone marrow, are among domestic animals most frequently recognized in cats but are relatively uncommon. A 4-year-old female Siamese, with splenomegaly and weight loss, was listless, anorectic, pale and dehydrated. A hemogram showed severe, macrocytic normochromic anemia, leukocytosis and reticulocytosis, with abnormally high numbers of nucleated RBC and undifferentiated blast cells. Bone marrow smears contained predominantly undifferentiated blast cells, RBC precursors and myeloblasts. The fluorescent antibody test for FeLV was positive. The cat died 66 days later despite a blood transfusion and chemotherapy. Necropsy confirmed a diagnosis of myeloproliferative disease, with hepatic and splenic invasion. 15 references, 5 figures, 1 table.

    Full Text Available Myeloproliferative neoplasms (MPN arise from genetic deficiencies at the level of pluripotent stem cells. Each of these neoplasms is a clonal stem cell disorder with specific phenotypic, genetic and clinical properties. Age is one of the most important factors in the development of symptoms and complications associated with MPNs.High white blood cell counts in chronic myelocytic leukemia also known as leukocytosis may lead to central nervous system findings. Tumors developing outside the bone marrow named as extramedullary myeloid tumors (EMMT could be detected at the initial diagnosis or during the prognosis of the disease, which may cause neurological symptoms due to pressure of leukemic cell mass on various tissues along with spinal cord. Central nervous system involvement and thrombocytopenic hemorrhage may lead to diverse neurological symptoms and findings.Transient ischemic attack and thrombotic stroke are the most common symptoms in polycythemia vera. Besides thrombosis and hemorrage, transformation to acute leukemia can cause neurological symptoms and findings. Transient ischemic attack, thrombotic stroke and specifically hemorrage can give rise to neurological symptoms similar to MPN in essential thrombocytosis.Extramedullary hematopoiesis refers to hematopoietic centers arise in organ/tissues other than bone marrow in myelofibrosis. Extramedullar hematopoietic centers may cause intracranial involvement, spinal cord compression, seizures and hydrocephalia. Though rare, extramedullary hematopoiesis can be detected in cranial/spinal meninges, paraspinal tissue and intracerebral regions. Extramedullary hematopoiesis has been reported in peripheral neurons, choroid plexus, pituitary, orbits, orbital and lacrimal fossa and in sphenoidal sinuses. [Cukurova Med J 2013; 38(2.000: 157-169

    In the myeloablative transplant setting, the early use of fluconazole prophylaxis provides a benefit in overall survival. Recent changes in transplantation practices, including the use of peripheral blood stem cells (PBSC) and/or reduced intensity conditioning (RIC) regimen may have favorably impacted the epidemiology of invasive fungal infections (IFI) after allogeneic stem cell transplantation (allo-SCT). Yet, the impact of removing fluconazole prophylaxis after RIC PBSC allotransplant is ill known. Here, a retrospective analysis was performed comparing patients who received fluconazole as antifungal prophylaxis (n = 53) or not (n = 56) after allo-SCT for acute leukemia or myelodysplastic/myeloproliferative syndrome. Sixteen IFI were documented (14 %) at a median time of 103 days after transplantation, including eight before day +100, at a similar rate, whether the patients received fluconazole prophylaxis (13 %) or not (16 %). IFI were due mainly to Aspergillus species (87 %), and only two Candida-related IFI (13 %) were documented in the non-fluconazole group before day +100. The incidences of IFI (overall, before or after day +100) as well as 3-year overall and disease-free survival, non-relapse mortality, or acute and chronic graft-versus-host disease (GVHD) were similar between both groups. In conclusion, this study suggests that fluconazole may not be required at the initial phase of RIC allo-SCT using PBSC. This result has to be confirmed prospectively while Aspergillus prophylaxis should be discussed in this particular setting.

    Purpose: The PARP inhibitor veliparib delays DNA repair and potentiates cytotoxicity of multiple classes of chemotherapy drugs, including topoisomerase I inhibitors and platinating agents. This study evaluated veliparib incorporation into leukemia induction therapy using a previously described topotecan/carboplatin backbone.Experimental Design: Employing a 3+3 trial design, we administered escalating doses of veliparib combined with topotecan + carboplatin in relapsed or refractory acute leukemias, aggressive myeloproliferative neoplasms (MPN), and chronic myelomonocytic leukemia (CMML).Results: A total of 99 patients received veliparib 10-100 mg orally twice daily on days 1-8, 1-14, or 1-21 along with continuous infusion topotecan 1.0-1.2 mg/m(2)/d + carboplatin 120-150 mg/m(2)/d on days 3-7. The MTD was veliparib 80 mg twice daily for up to 21 days with topotecan 1.2 mg/m(2)/d + carboplatin 150 mg/m(2)/d. Mucositis was dose limiting and correlated with high veliparib concentrations. The response rate was 33% overall (33/99: 14 CR, 11 CRi, 8 PR) but was 64% (14/22) for patients with antecedent or associated aggressive MPNs or CMML. Leukemias with baseline DNA repair defects, as evidenced by impaired DNA damage-induced FANCD2 monoubiquitination, had improved survival [HR = 0.56 (95% confidence interval, 0.27-0.92)]. A single 80-mg dose of veliparib, as well as veliparib in combination with topotecan + carboplatin, induced DNA damage as manifested by histone H2AX phosphorylation in CD34(+) leukemia cells, with greater phosphorylation in cells from responders.Conclusions: The veliparib/topotecan/carboplatin combination warrants further investigation, particularly in patients with aggressive MPNs, CMML, and MPN- or CMML-related acute leukemias.

    Full Text Available According to the 2008 revision of the World Health Organization (WHO classification of myeloid malignancies, philadelphia chromosome (Ph-negative myeloproliferative neoplasms (MPNs include clonal, hematologic disorders such as polycythemia vera, primary myelofibrosis, and essential thrombocythemia. Recent years have witnessed major advances in the understanding of the molecular pathophysiology of these rare subgroups of chronic, myeloproliferative disorders. Identification of somatic mutations in genes associated with pathogenesis and evolution of these myeloproliferative conditions (Janus Kinase 2; myeloproliferative leukemia virus gene; calreticulin led to substantial changes in the international guidelines for diagnosis and treatment of Ph-negative MPN during the last few years. The MPN-Working Group (MPN-WG, a panel of hematologists with expertise in MPN diagnosis and treatment from various parts of India, examined applicability of this latest clinical and scientific evidence in the context of hematology practice in India.This manuscript summarizes the consensus recommendations formulated by the MPN-WG that can be followed as a guideline for management of patients with Ph-negative MPN in the context of clinical practice in India.

    Sleep disorders have a profound and well-documented impact on overall health and quality of life in the general population. In patients with chronic disease, sleep disorders are more prevalent, with an additional morbidity and mortality burden. The complex and dynamic relationship between sleep disorders and chronic kidney disease (CKD) remain relatively little investigated. This article presents an overview of sleep disorders in patients with CKD, with emphasis on relevant pathophysiologic underpinnings and clinical presentations. Evidence-based interventions will be discussed, in the context of individual sleep disorders, namely sleep apnea, insomnia, restless leg syndrome and excessive daytime sleepiness. Limitations of the current knowledge as well as future research directions will be highlighted, with a final discussion of different conceptual frameworks of the relationship between sleep disorders and CKD.

    The finding of somatically acquired uniparental disomy, where both copies of a chromosome pair or parts of chromosomes have originated from one parent, has led to the discovery of several novel mutated genes in myeloproliferative neoplasms and related disorders. This article examines how the development of single nucleotide polymorphism array technology has facilitated the identification of regions of acquired uniparental disomy and has led to a much greater understanding of the molecular pathology of these heterogeneous diseases.

    It has long been recognized that there is a relationship between certain personality types and personality disorders (PD) and chronic nonmalignant pain (CP). The relationship, however, is far from understood and the physiological and psychological mechanisms that underlie it are unclear. Those who treat chronic pain face many challenges when dealing with individuals who have personality disorders and they often become frustrated when interacting with these patients. Patients with certain traits and personality disorders may continue to worry and ruminate about their symptoms long after the tissue pathology has resolved. Other individuals may overly rely on the clinician and assume a passive role in their treatment, thereby decreasing the likelihood for a positive outcome. Moreover, patients with personality disorders may be demanding (eg, borderline), self-absorbed (eg, narcissistic), or substance seeking (eg, antisocial, borderline). In an attempt to improve management of such patients, pain specialists have attempted to better understand the complex relationship between personality and chronic pain. In this article, we will review the predominant historical and current theories of pain and personality, discuss aspects of the gate-control theory of pain that may relate to personality, and discuss the diathesis-stress model of personality disorders in pain. Last, we will review studies of personality and personality disorders in chronic pain and their treatment implications. We conclude that, based on the underlying neurochemistry, there may be a direct or indirect link between PD and CP, but further prospective research, both on the biological and psychological relationship, should be conducted.

    Full Text Available The progress in Medical and Nursing Science has contributed significantly to the lengthening of life expectancy regarding several categories of ill people with chronic diseases. However, when the quality of life depends on the periodic correction of biological parameters, as with people with chronic renal failure, this situation affects both the patient and the environment. The aim of the present study is the evaluation of psychiatric disorders which are presented in haemodialysis patients as well as the influence of these disorders on their quality of life. Material and method: Review of relative bibliography was made in electronic basis of Medline (1980‐2009 using as key words haemodialysis, chronic renal failure, quality of life, psychiatric disorders. Complementary bibliography was found through other electronic search engines. Results: The chronic character and the frequency of renal failure, the possible dysfunction in the movement as well as the necessary long treatment cause problems, which extend the disease beyond the medical area offering socioeconomic dimensions, which complicate the associated psychiatric disorders. Conclusions: These patients suffer from the disease as well as from the treatment and at the same time they are faced with the number of the accompanying and interrelated problems, which come up in their everyday living and prescribe restrictively their way of life.

    This article explores problems of voicelessness in Isabel Allende’s Paula (1995) through a focus on the story of Paula’s illness and subsequent death from porphyria in 1992. I argue that the language, categories and stories through which disorders of consciousness are constructed are central to ethical decision-making and shifting cultural understandings of these conditions. In Paula, Allende uses an experimental, hybrid narrative form that draws on illness narrative, magical realist novel, national history, letters, and memoir to challenge traditional depictions of “coma” and to create a new public space through which these issues of voicelessness can be addressed.

    Brand, Bethany L; Lanius, Ruth A

    2014-01-01

    Emotion dysregulation is a core feature of chronic complex dissociative disorders (DD), as it is for borderline personality disorder (BPD). Chronic complex DD include dissociative identity disorder (DID) and the most common form of dissociative disorder not otherwise specified (DDNOS, type 1), now known as Other Specified Dissociative Disorders (OSDD, type 1). BPD is a common comorbid disorder with DD, although preliminary research indicates the disorders have some distinguishing features as well as considerable overlap. This article focuses on the epidemiology, clinical presentation, psychological profile, treatment, and neurobiology of chronic complex DD with emphasis placed on the role of emotion dysregulation in each of these areas. Trauma experts conceptualize borderline symptoms as often being trauma based, as are chronic complex DD. We review the preliminary research that compares DD to BPD in the hopes that this will stimulate additional comparative research.

These diseases not only share overlapping chromosomal abnormalities but also a number of acquired somatic mutations. Recently, mutations in a putative tumor suppressor gene, ten-eleven translocation 2 (TET2 on chromosome 4q24 have been identified in 12% of patients with MPN. Additionally 4q24 chromosomal rearrangements in MPN, including TET2 deletions, have also been observed using conventional cytogenetics. The goal of this study was to investigate the frequency of genomic TET2 rearrangements in MPN using fluorescence in situ hybridization as a more sensitive method for screening and identifying genomic deletions. Among 146 MPN patients, we identified two patients (1.4% who showed a common 4q24 deletion, including TET2. Our observations also indicated that the frequency of TET2 deletion is increased in patients with an abnormal karyotype (5%.Keywords: TET2, myeloproliferative neoplasms, fluorescence in situ hybridization, cytogenetics

    Full Text Available The paper reviews the present-day Russian and foreign literature on neuromuscular disorders in chronic alcohol intoxication. The most common manifestations of alcohol disease include alcoholic polyneuropathy (PNP and alcohol-induced skeletal muscle injury. The clinical polymorphism of alcoholic PNP is discussed. The paper considers a chronic sensory automatic form due to the direct toxic effects of ethanol and its metabolites during long-term alcohol intoxication, as well as acute/subacute sensorimotor neuropathy, the basis for the pathogenesis of which is B group vitamins, predominantly thiamine, deficiency that develops in the presence of drinking bouts concurrent with malnutrition and/or alcohol-related gastrointestinal tract diseases. In addition to nonuse of alcohol and a properly balanced diet, antioxidant therapy with alphalipoic acid and neurotropic B group vitamins is considered to be pathogenetic therapy for neuropathy. The most common and least studied clinicalform of alcohol-induced musculoskeletal injury is chronic alcoholic myopathy (AM, the diagnostic standard for which is morphometricand immunohistochemical examination of a muscle biopsy specimen. The morphological base for this form of myopathy is predominantly type 2 muscle fiber atrophy caused by impaired protein synthesis and a decreased regenerative potential of muscle fiber. The efficacy of antioxidants and leucine-containing amino acid mixtures in the treatment of chronic AM is discussed.

    The ability to work is important to those with chronic neurologic disorders (CND) and to the aging workforce. Many signs and symptoms are similar in those with CND and normal aging, but may interfere with the ability to work if not appropriately accommodated. This requires the healthcare provider to recognize the specific features of the CND that interferes with work and how it can be accommodated. Review of the American with Disabilities Act and the subsequent amendment informs the healthcare provider as to what is covered under the law and how the disability can be accommodated. Overall employers want to retain qualified employees and therefore accommodating workers is beneficial to both the employee with CND and the employer.

    Myeloproliferative neoplasms are characterized by a common stem cell-derived clonal proliferation, but are phenotypically diverse. JAK2 is mutated (V617F) in more than 90 % of patients with polycythemia vera (PV) and approximately 60 % of patients with essential thrombocythemia (ET) or primary myelofibrosis (PMF). Pulmonary arterial hypertension (PAH) is a major complication of several hematological disorders. Chronic myeloproliferative disorders associated with PAH have been included in group five for which the etiology is unclear and/or multifactorial. The aim of this study is to screen Egyptian Philadelphia negative JAK2 positive myeloproliferative neoplasm patients for the presence of PAH and its correlation with JAK2 allele burden. We also made a review for correlation of JAK2 allele with hematological parameters comparing our results to others. We enrolled 60 patients with Philadelphia negative myeloproliferative neoplasms. All patients enrolled in the study were subjected to laboratory and imaging workup in the form of CBC, liver, kidney profile, bone marrow examination, abdominal ultrasonography, and transthoracic echocardiography. Our results revealed that 7 patients out of 60 (11.67 %) had pulmonary arterial hypertension, 3 patients with PMF, 2 patients with PRV, and 2 patients with ET, and its correlation with JAK2 allele burden was not statistically significant. Correlation analysis between JAK2 V617F allele burden and other parameters revealed: statistical significant correlation with age, HB, HCT, PLT, UA, LDH, and splenic diameter but insignificant correlation with WBCs and PAH. Pulmonary arterial hypertension prevalence in our study was 11.67 % and no significant correlation with JAK 2 allele burden. Our study is the largest one up to our knowledge that studies the association between its prevalence and JAK2 burden.

  10. Thyroid Disorders and Chronic Kidney Disease

    Full Text Available Thyroid hormones play a very important role regulating metabolism, development, protein synthesis, and influencing other hormone functions. The two main hormones produced by the thyroid are triiodothyronine (T3 and thyroxine (T4. These hormones can also have significant impact on kidney disease so it is important to consider the physiological association of thyroid dysfunction in relation to chronic kidney disease (CKD. CKD has been known to affect the pituitary-thyroid axis and the peripheral metabolism of thyroid hormones. Low T3 levels are the most common laboratory finding followed by subclinical hypothyroidism in CKD patients. Hyperthyroidism is usually not associated with CKD but has been known to accelerate it. One of the most important links between thyroid disorders and CKD is uremia. Patients who are appropriately treated for thyroid disease have a less chance of developing renal dysfunction. Clinicians need to be very careful in treating patients with low T3 levels who also have an elevation in TSH, as this can lead to a negative nitrogen balance. Thus, clinicians should be well educated on the role of thyroid hormones in relation to CKD so that proper treatment can be delivered to the patient.

    Chronic craniofacial pain involves the head, face and oral cavity and is associated with significant morbidity and high levels of health care utilization. A bidirectional relationship is suggested in the literature for poor sleep and pain, and craniofacial pain and sleep are reciprocally related. We review this relationship and discuss management options. Part I reviews the relationship between pain and sleep disorders in the context of four diagnostic categories of chronic craniofacial pain: 1) primary headaches: migraines, tension-type headache (TTH), trigeminal autonomic cephalalgias (TACs) and hypnic headache, 2) secondary headaches: sleep apnea headache, 3) temporomandibular joint disorders (TMD) and 4) painful cranial neuropathies: trigeminal neuralgia, post-herpetic trigeminal neuropathy, painful post-traumatic trigeminal neuropathy (PTTN) and burning mouth syndrome (BMS). Part II discusses the management of patients with chronic craniofacial pain and sleep disorders addressing the factors that modulate the pain experience as well as sleep disorders and including both non-pharmacological and pharmacological modalities.

    The aim of this study was to investigate the functional condition of the stomatognathic system in children suffering from juvenile chronic arthritis, with respect to bite force and temporomandibular disorder in relation to radiographic abnormalities of the mandibular condyle, occlusal factors and systemic disease parameters. Thirty-five children with juvenile chronic arthritis were compared to 89 healthy children with an Angle Class I occlusion and 62 children with an Angle Class II malocclusion. Subjective symptoms and clinical signs of temporomandibular disorder and radiographic mandibular condylar changes were more common in children with juvenile chronic arthritis than in the two comparison groups. Maximal molar and incisal bite forces and maximal molar bite force endurance times were also significantly reduced in children with juvenile chronic arthritis. It is concluded that the differences between the groups are caused mainly by the systemic inflammatory disease itself, but a functional influence of weakened masticatory muscles cannot be excluded.

    Myeloproliferative neoplasms (MPN) include polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF). These disorders may undergo phenotypic shifts, and may specifically evolve into secondary myelofibrosis (MF) or acute myeloid leukemia (AML). We studied genomic changes associated with these transformations in 29 patients who had serial samples collected in different phases of disease. Genomic DNA from granulocytes, i.e., the myeloproliferative genome, was processed and hybridized to genome-wide human SNP 6.0 arrays. Most patients in chronic phase had chromosomal regions with uniparental disomy (UPD) and/or copy number changes. Disease progression to secondary MF or AML was associated with the acquisition of additional chromosomal aberrations in granulocytes (P = 0.002). A close relationship was observed between aberrations of chromosome 9p (UPD and/or gain) and progression from PV to post-PV MF (P = 0.002). The acquisition of one or more aberrations involving chromosome 5, 7, or 17p was specifically associated with progression to AML (OR 5.9, 95% CI 1.2-27.7, P = 0.006), and significantly affected overall survival (HR 18, 95% CI 1.9-164, P = 0.01). These observations indicate that disease progression from chronic-phase MPN to secondary MF or AML is associated with specific chromosomal aberrations that can be detected by means of high-resolution SNP array analysis of granulocyte DNA.

    Introducción: La enfermedad pulmonar obstructiva crónica (EPOC) se caracteriza por obstrucción crónica del flujo aéreo y se asocia frecuentemente a alteraciones endocrino-metabólicas que empeoran la situación clínica del paciente y su pronóstico. El conocimiento en profundidad de estas alteraciones en los pacientes con EPOC permite llevar a cabo medidas preventivas, detección temprana e intervenciones nutricionales adecuadas. Objetivos: Analizar la prevalencia de comorbilidades endocrino-metabólicas en pacientes con EPOC y los factores de riesgo que favorecen la aparición de dichas enfermedades. Métodos: Se desarrolló una estrategia de búsqueda exhaustiva de la literatura limitada a los últimos diez años, en las bases de datos PubMed, Scopus y ScienceDirect, usando las palabras clave “endocrine metabolic disorders AND COPD”, “endocrine disorders AND COPD” y “metabolic disorders AND COPD”. ”. En el análisis bibliográfico se excluyeron aquellos artículos cuyo título o contenido no se correspondía con el objetivo del presente estudio, así como los artículos duplicados en las bases de datos. Finalmente, tras una profunda lectura crítica, fueron seleccionados y analizados 17 artículos. Resultados: El análisis de los artículos ha mostrado una relación significativa entre la EPOC y la presencia de alteraciones endocrino-metabólicas tales como diabetes mellitus, síndrome metabólico, obesidad, osteoporosis e hipogonadismo. Los autores coinciden en la alta prevalencia de estas comorbilidades, que influyen de forma diferente en el desarrollo de la EPOC. Conclusiones: Debido a la alta prevalencia y asociación con la EPOC, estas comorbilidades han de ser tenidas en cuenta por el profesional sanitario, ya que pueden afectar su abordaje, intervención y resultados.

    Full Text Available Long-term therapy with the macrolide antibiotic erythromycin was shown to alter the clinical course of diffuse panbronchiolitis in the late 1980s. Since that time, macrolides have been found to have a large number of anti-inflammatory properties in addition to being antimicrobials. These observations provided the rationale for many studies performed to assess the usefulness of macrolides in other inflammatory diseases including skin and hair disorders, such as rosacea, psoriasis, pityriasis rosea, alopecia areata, bullous pemphigoid, and pityriasis lichenoides. This paper summarizes a collection of clinical studies and case reports dealing with the potential benefits of macrolides antibiotics in the treatment of selected dermatoses which have primarily been classified as noninfectious and demonstrating their potential for being disease-modifying agents.

    Unlike acute pain that warns us of injury or disease, chronic or persistent pain serves no adaptive purpose. Though there is no agreed on definition of chronic pain, it is commonly referred to as pain that is without biological value, lasting longer than the typical healing time, not responsive to treatments based on specific remedies, and of a duration greater than 6 months. Chronic pain that is severe and intractable has detrimental consequences, including psychological distress, job loss, social isolation, and, not surprisingly, it is highly comorbid with depression and anxiety. Historically, pain without an apparent anatomical or neurophysiological origin was labelled as psychopathological. This approach is damaging to the patient and provider alike. It pollutes the therapeutic relationship by introducing an element of mutual distrust as well as implicit, if not explicit, blame. It is demoralizing to the patient who feels at fault, disbelieved, and alone. Moreover, many medically unexplained pains are now understood to involve an interplay between peripheral and central neurophysiological mechanisms that have gone awry. The new Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, somatic symptom disorder overpsychologizes people with chronic pain; it has low sensitivity and specificity, and it contributes to misdiagnosis, as well as unnecessary stigma. Adjustment disorder remains the most appropriate, accurate, and acceptable diagnosis for people who are overly concerned about their pain.

    Full Text Available With the discovery of the JAK2V617F mutation in patients with Philadelphia chromosome-negative (Ph− myeloproliferative neoplasms (MPNs in 2005, major advances have been made in the diagnosis of MPNs, in understanding of their pathogenesis involving the JAK/STAT pathway, and finally in the development of novel therapies targeting this pathway. Nevertheless, it remains unknown which mutations exist in approximately one-third of patients with non-mutated JAK2 or MPL essential thrombocythemia (ET and primary myelofibrosis (PMF. At the end of 2013, two studies identified recurrent mutations in the gene encoding calreticulin (CALR using whole-exome sequencing. These mutations were revealed in the majority of ET and PMF patients with non-mutated JAK2 or MPL but not in polycythemia vera patients. Somatic 52-bp deletions (type 1 mutations and recurrent 5-bp insertions (type 2 mutations in exon 9 of the CALR gene (the last exon encoding the C-terminal amino acids of the protein calreticulin were detected and found always to generate frameshift mutations. All detected mutant calreticulin proteins shared a novel amino acid sequence at the C-terminal. Mutations in CALR are acquired early in the clonal history of the disease, and they cause activation of JAK/STAT signaling. The CALR mutations are the second most frequent mutations in Ph− MPN patients after the JAK2V617F mutation, and their detection has significantly improved the diagnostic approach for ET and PMF. The characteristics of the CALR mutations as well as their diagnostic, clinical, and pathogenesis implications are discussed in this review.

  8. Sleep-related disorders in chronic obstructive pulmonary disease.

    2014-02-01

    Sleep may have several negative consequences in patients with chronic obstructive pulmonary disease (COPD). Sleep is typically fragmented with diminished slow wave and rapid-eye-movement sleep, which likely represents an important contributing factor to daytime symptoms such as fatigue and lethargy. Furthermore, normal physiological adaptations during sleep, which result in mild hypoventilation in normal subjects, are more pronounced in COPD, which can result in clinically important nocturnal oxygen desaturation. The co-existence of obstructive sleep apnea and COPD is also common, principally because of the high prevalence of each disorder, and there is little convincing evidence that one disorder predisposes to the other. Nonetheless, this co-existence, termed the overlap syndrome, typically results in more pronounced nocturnal oxygen desaturation and there is a high prevalence of pulmonary hypertension in such patients. Management of sleep disorders in patients with COPD should address both sleep quality and disordered gas exchange. Non-invasive pressure support is beneficial in selected cases, particularly during acute exacerbations associated with respiratory failure, and is particularly helpful in patients with the overlap syndrome. There is limited evidence of benefit from pressure support in the chronic setting in COPD patients without obstructive sleep apnea.

    Full Text Available Andrew L Sochacki,1 Melissa A Fischer,1 Michael R Savona1,2 1Department of Internal Medicine, Vanderbilt University Medical Center, 2Vanderbilt-Ingram Cancer Center, Nashville, TN, USA Abstract: The discovery of JAK2V617F a decade ago led to optimism for a rapidly developing treatment revolution in Ph- myeloproliferative neoplasms. Unlike BCR–ABL, however, JAK2 was found to have a more heterogeneous role in carcinogenesis. Therefore, for years, development of new therapies was slow, despite standard treatment options that did not address the overwhelming symptom burden in patients with primary myelofibrosis (MF, post-essential thrombocythemia MF, post-polycythemia vera MF, and myelodysplastic syndrome (MDS/myeloproliferative neoplasm (MPN syndromes. JAK–STAT inhibitors have changed this, drastically ameliorating symptoms and ultimately beginning to show evidence of impact on survival. Now, the genetic foundations of myelofibrosis and MDS/MPN are rapidly being elucidated and contributing to targeted therapy development. This has been empowered through updated response criteria for MDS/MPN and refined prognostic scoring systems in these diseases. The aim of this article is to summarize concisely the current and rationally designed investigational therapeutics directed at JAK–STAT, hedgehog, PI3K–Akt, bone marrow fibrosis, telomerase, and rogue epigenetic signaling. The revolution in immunotherapy and novel treatments aimed at previously untargeted signaling pathways provides hope for considerable advancement in therapy options for those with chronic myeloid disease.

    Full Text Available Background Chronic pelvic pain (CPP is a complex condition wich is associated with emotional factors, specially depression and anxiety. Objectives To make a systematic review to provide a detailed summary of relevant literature on the association between CPP and different psychiatric disorders/symptoms. Methods A systematic review of articles in the international literature published between 2003 and 2014 was performed in the electronic databases PubMed, PsycINFO, LILACS, and SciELO using the terms (chronic pelvic pain AND (psychiatry OR psychiatric OR depression OR anxiety OR posttraumatic stress OR somatoform. The searches returned a total of 529 matches that were filtered according to predefined inclusion and exclusion criteria. A total of 18 articles were selected. Results The investigations focused mainly on the assessment of depression and anxiety disorders/symptoms, with rather high rates (17-38.6%. Depression and anxiety symptoms were more prevalent among women with CPP compared to healthy groups. Comparisons between groups with CPP and with specific pathologies that also have pain as a symptom showed that depression indicators are more frequent in CPP. Depressive symptoms tend to be more common in CPP and have no particular association with pain itself, the core feature of CPP. Discussion Other aspects of CPP seem to play a specific role in this association. Anxiety and other psychiatric disorders require further investigation so that their impact on CPP can be better understood.

    Association of myeloproliferative neoplasm (MPN) with lymphoproliferative neoplasm (LPN) has been occasionally reported. The aim of this study, which included 353 patients with polycythemia vera and 467 with essential thrombocythemia, was to assess whether the risk of developing LPN is increased in MPN patients. Expected numbers of LPN incident cases were calculated based on 5-year age group, gender, and calendar time-specific cancer incidence rates in the general population of the same area. Standardized incidence ratios were computed to estimate the relative risk of developing LPN. Analyses were carried out for the whole series and then separately for essential thrombocythemia and polycythemia vera, gender, and JAK2V617F genotype. With 4,421 person-years, we found 11 patients developing LPN, including four chronic lymphocytic leukemias, five non-Hodgkin's lymphomas, and two plasma cell disorders, after a median interval time of 68 months from MPN diagnosis. Cumulative risk to develop LPN at 5 and 10 years was 0.93% (95% confidence interval, 0.39-2.22) and 2.96% (95% confidence interval, 1.52-5.72), respectively. There was a 3.44-fold increased risk of LPN compared with the general population, ranging from 2.86 for plasma cell disorder to 12.42 for chronic lymphocytic leukemia; the risk was significantly increased in JAK2V617F mutated patients (5.46-fold) and in males (4.52-fold). The JAK2V617F mutation was found in lymphoid tumor cells in two of three cases evaluated, indicating that, in some patients, LPN originated in a JAK2V617F mutated common lymphoid-myeloid hematopoietic progenitor cell. We conclude that the risk of developing LPN is significantly increased in MPN patients compared with the general population.

    Because temporomandibular disorders (TMDs) rehabilitation continues to be a challenge, a more comprehensive picture of the orofacial functions in patients with chronic pain is required. This study assessed the orofacial functions, including surface electromyography (EMG) of dynamic rhythmic activities, in patients with moderate-severe signs and symptoms of chronic TMD. It was hypothesized that orofacial motor control differs between patients with moderate-severe chronic TMD and healthy subjects. Seventy-six subjects (46 with TMD and 30 control) answered questionnaires of severity of TMD and chewing difficulties. Orofacial functions and EMG during chewing were assessed. Standardized EMG indices were obtained by quantitative analysis of the differential EMG signals of the paired masseter and temporal muscles, and used to describe muscular action during chewing. TMD patients showed significant greater difficulty in chewing; worse orofacial scores; longer time for free mastication; a less accurate recruitment of the muscles on the working and balancing sides, reduced symmetrical mastication index (SMI) and increased standardized activity during EMG test than healthy subjects. SMI, TMD severity and orofacial myofunctional scores were correlated (Porofacial functions and increased activity of the muscles of balancing sides during unilateral chewing characterized the altered orofacial motor control in patients with moderate-severe chronic TMD. Implications for rehabilitation are discussed.

    Full Text Available Objectives: Diagnostic laparoscopy has become an integral part of general surgical procedures with the recent advancements in laparoscopic technology. Since surgeons are more oriented in viewing and dissection of different intra-abdominal areas and are proficient in the definitive management of complications in the procedures, diagnostic laparoscopy may be better off in the hands of surgeons. Laparoscopy has proved to be an important tool in final minimally invasive exploration for selected medical patients with chronic abdominal disorders, the diagnosis of which remains uncertain despite employing the requisite laboratory and non-invasive imaging investigations. This retrospective study was done to evaluate the accuracy of elective diagnostic laparoscopy in patients with chronic abdominal disorders and its impact on the management of these patients. Methods: The records of 35 patients, admitted to Riyadh Medical Complex with chronic abdominal disorders and referred to the author by physicians for elective diagnostic laparoscopy from 1999 through 2004, were evaluated for the accuracy and impact of this procedure in the further management of these patients. All 35 patients were investigated by the referring physician. Investigations included hematology, biochemistry, radiology, ascitic fluid analysis, endoscopic and imaging studies and the Mantoux test. These investigations suggested abdominal tuberculosis in 22 patients and intra-abdominal malignancy in 13 patients. They were referred for elective diagnostic laparoscopy and tissue biopsy. Results: Diagnostic laparoscopy confirmed the diagnosis in all patients suspected of malignancy. In patients with suspected abdominal tuberculosis, the laparoscopic diagnosis and biopsy revealed tuberculosis (16 patients, liver cirrhosis (2 patients, Crohn′s disease (1 patient, and metastatic carcinoma of terminal ileum (1 patient. In 2 patients the procedure did not reveal any specific pathology. The

    Myeloid and lymphoid neoplasms with fibroblast growth factor receptor 1 (FGFR1) abnormalities, also known as 8p11 myeloproliferative syndrome (EMS), represent rare and aggressive disorders, associated with chromosomal aberrations that lead to the fusion of FGFR1 to different partner genes. We report on a third patient with a fusion of the translocated promoter region (TPR) gene, a component of the nuclear pore complex, to FGFR1 due to a novel ins(1;8)(q25;p11p23). The fact that this fusion is a rare but recurrent event in EMS prompted us to examine the localization and transforming potential of the chimeric protein. TPR-FGFR1 localizes in the cytoplasm, although the nuclear pore localization signal of TPR is retained in the fusion protein. Furthermore, TPR-FGFR1 enables cytokine-independent survival, proliferation, and granulocytic differentiation of the interleukin-3 dependent myeloid progenitor cell line 32Dcl3, reflecting the chronic phase of EMS characterized by myeloid hyperplasia. 32Dcl3 cells transformed with the TPR-FGFR1 fusion and treated with increasing concentrations of the tyrosine kinase inhibitors ponatinib (AP24534) and infigratinib (NVP-BGJ398) displayed reduced survival and proliferation with IC50 values of 49.8 and 7.7 nM, respectively. Ponatinib, a multitargeted tyrosine kinase inhibitor, is already shown to be effective against several FGFR1-fusion kinases. Infigratinib, tested only against FGFR1OP2-FGFR1 to date, is also efficient against TPR-FGFR1. Taking its high specificity for FGFRs into account, infigratinib could be beneficial for EMS patients and should be further investigated for the treatment of myeloproliferative neoplasms with FGFR1 abnormalities.

  18. Chronic disorders of consciousness following coma: Part one: medical issues.

    Increasing numbers of patients survive traumatic brain injury (TBI) and cardiopulmonary arrest and resuscitation and are admitted to the ICU in coma. Some of these patients become brain dead; others regain consciousness. Still others become vegetative or minimally conscious, conditions called chronic disorders of consciousness and ultimately are cared for outside the ICU. Comatose patients lack the wakefulness and awareness that distinguish consciousness from unconsciousness. Vegetative patients are awake in that they manifest sleep-wake cycles, but they are unaware of their environment and cannot respond to stimuli. Minimally conscious patients are awake, aware to a limited extent, and somewhat responsive. The diagnosis of the vegetative and minimally conscious states has been based largely on their behavioral and pathologic features, and it has been believed that vegetative patients remain in that condition permanently. Nevertheless, EEG and neuroimaging studies suggest that the traditional diagnostic approach is imprecise. Moreover, clinical investigations have revealed that some vegetative patients can become minimally conscious and that some minimally conscious patients can gain increased awareness. Few therapies for patients with chronic disorders of consciousness have been subjected to randomized trials. Furthermore, although a small number of patients have improved neurologically with or without treatment, their overall prognosis for neurologic recovery remains poor.

    A 3 months old girl presented with significant enlargement of liver, spleen and lymphnodes, with moderate anemia, thrombopenia and leucocytosis. In the differential count there was a shift to the left and an increase of monocyte-like cells (35%). Differential diagnosis included leucemoid reaction, infectious mononucleosis, myelo-proliferative disorder with a missing C chromosome and chronic myeloid leucemia. Clinical symptoms, cytochemistry and caryotype of bone marrow cells suggested infantile chronic myeloic leucemia and normal ALP index and possibly normal HbF. Treatment with 6-mercaptopurine was followed by partial remission. The therapeutic consequences of exact differential diagnosis are discussed.

    This review first reports on the data concerning the relationship between migraine and personality traits and psychiatric disorders. The relationship between migraine and tenderness of the pericranial and cervical muscles is then discussed. In one study, a psychologic assessment was performed in 56 women with migraine, and the Minnesota Multiphase Personality Inventory (MMPI) and State Trait Anxiety Inventory were administered at baseline (T0) and after 6-7 years (T2). Frequency, severity and duration of migraine were recorded at T0, after treatment (T1) and at T2, and their relationship to the prevalence of depression, MMPI and State Trait Anxiety Inventory data were examined. Pain parameters improved in all patients in T0-1, but were higher at T2 in patients with depression at T0. The patients whose migraine improved at T2 had significantly lower MMPI and State Trait Anxiety Inventory scores at T0 and T2. Moreover, the prevalence of depression of the patients whose migraine improved at T2 was 37.5% at T0 and decreased to 12.5% at T2. The authors subsequently studied the function of the frontal lobe in 23 female patients previously treated for chronic migraine and 23 controls by applying three neuropsychologic tests (gambling task, tower of hanoi-3 and object alternation test). The patient group performed significantly worse on the tower of hanoi-3 and the object alternation test. In order to assess the extent to which muscle tenderness may relate to psychiatric disorders in patients with migraine and tension-type headache, diagnosed according International Headache Society criteria [2004], a psychologic assessment was performed and palpation tenderness scores calculated for the pericranial and cervical muscles in 459 patients. In total, 125 patients had frequent episodic migraine, 97 had chronic migraine, 82 had frequent episodic tension-type headache and chronic tension-type headache was present in 83. In a further 72 patients, both episodic migraine and

    Myeloproliferative neoplasms (MPN) are clonal stem cell diseases, first conceptualized in 1951 by William Dameshek, and historically included chronic myeloid leukemia (CML), polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF). In 1960, Nowell and Hungerford discovered an invariable association between the Philadelphia chromosome (subsequently shown to harbor the causal BCR-ABL1 mutation) and CML; accordingly, the term MPN is primarily reserved for PV, ET, and PMF, although it includes other related clinicopathologic entities, according to the World Health Organization (WHO) classification system. In 2005, William Vainchenker and others described a Janus kinase 2 mutation (JAK2V617F) in MPN and this was followed by a series of additional descriptions of mutations that directly or indirectly activate JAK-STAT: JAK2 exon 12, myeloproliferative leukemia virus oncogene (MPL) and calreticulin (CALR) mutations. The discovery of these, mostly mutually exclusive, "driver" mutations has contributed to revisions of the WHO diagnostic criteria and risk stratification in MPN. Mutations other than JAK2, CALR and MPL have also been described in MPN and shown to provide additional prognostic information. From the standpoint of treatment, over the last 50 years, Louis Wasserman from the Unites States and Tiziano Barbui from Italy had skillfully organized and led a number of important clinical trials, whose results form the basis for current treatment strategies in MPN. More recently, allogeneic stem cell transplant, as a potentially curative treatment modality, and JAK inhibitors, as palliative drugs, have been added to the overall therapeutic armamentarium in myelofibrosis. In the current review, I will summarize the important advances made in the last 10 years regarding the science and practice of MPN.

    Proper level of pressure or compression generated by medical stocking or hosiery is the key element for successful treatment or management of chronic venous disorders such as oedema, leg ulcers, etc. However achieving the recommended compression level and, more importantly, sustaining it using stockings has been a major challenge to the health practitioners supervising the treatment. This work aims to investigate and design a smart compression stocking using shape-memory polymer that allows externally controlling the pressure level in the wrapped position on the leg. Based on thermodynamical rubber theories, we first derived several criteria that have to be satisfied simultaneously in order to achieve the controlled pressure adjustment using external heat stimuli. We then presented a case where such a stocking is developed using a blend yarn consists of selected shape-memory polyurethane and nylon filaments. Extensive experimental work has also been conducted to demonstrate the feasibility and explore the influencing factors involved.

Due to the lack of valid diagnostic tools and criteria, very few cases are seen in clinical practice and are often misdiagnosed. Misdiagnosis can lead to inappropriate treatment that may increase the risk of morbidity or suicidality. In this paper, we present the case of a 35-year-old male who needed support in breathing from a mechanical ventilator and developed neuropsychiatric behavioral problems following ingestion of OP compounds, which lead to suicidality. The patient was treated by the psychiatric team with antipsychotic and antidepressants and improved following the regular use of medication. Keywords: COPIND, mood liability, suicidal thoughts

    Full Text Available Chronic renal failure (CRF is one of the best known renal diseases. It is characterized by a deterioration in the overall renal function and is associated with other conditions such as hypertension, diabetes mellitus, uropathy, chronic glomerulonephritis and autoimmune diseases. Patients with CRF show alterations of the masticatory system that are specific to the disease and other type of disorders as a result of treatment. Oral health in dialysis and transplant patients tends to be poor, which makes them more likely to develop pathological conditions in the oral cavity, potentially increasing morbidity, mortality and affecting the quality of life of patients. Among the lesions we can find dysgeusia, periodontitis, candidiasis, gingival bleeding, petechiae, and joint alterations. Gingivitis and xerostomia associated to long-term use medications can cause oral lesions. Children with CRF show two oral conditions of interest: high incidence of dental anomalies and low caries activity. In patients receiving a kidney transplant, previous dental treatment is critical because the immune status of the patient will be affected not only by the toxemia, but by the immunosuppressive drugs used to prevent transplant rejection. Therefore, the dentist plays an important role in training parents and/or guardians, doctors and paramedics on the treatment of oral lesions in these patients

    Full Text Available Cardiovascular disease is highly prevalent in patients with chronic renal failure (CRF. However, data on the impact of CRF on the cerebral circulatory system are scarce—despite the fact that stroke is the third most common cause of cardiovascular death in people with CRF. In the present study, we examined the impact of CRF on behavior (anxiety, recognition and ischemic stroke severity in a well-defined murine model of CRF. We did not observe any significant increases between CRF mice and non-CRF mice in terms of anxiety. In contrast, CRF mice showed lower levels of anxiety in some tests. Recognition was not impaired (vs. controls after 6 weeks of CRF but was impaired after 10 weeks of CRF. Chronic renal failure enhances the severity of ischemic stroke, as evaluated by the infarct volume size in CRF mice after 34 weeks of CRF. Furthermore, neurological test results in non-CRF mice tended to improve in the days following ischemic stroke, whereas the results in CRF mice tended to worsen. In conclusion, we showed that a murine model of CRF is suitable for evaluating uremic toxicity and the associated neurological disorders. Our data confirm the role of uremic toxicity in the genesis of neurological abnormalities (other than anxiety.

    Primary myelofibrosis (PMF) belongs to Ph- myeloproliferative diseases. The only curative treatment is hematopoietic stem cell transplantation (HSCT). Conservative treatment options comprise supportive care, especially administration of red blood cell and platelet transfusions, and medication. Hydroxyurea, interferon α, anagrelide, corticosteroids, androgens, or inhibitors of angiogenesis (thalidomide, lenalidomide, pomalidomide) may be used for treatment of PMF, depending on the clinical stage and disease symptoms present. Also splenectomy or radiotherapy of enlarged spleen have palliative potential. JAK2 kinase inhibitors represent a novel class of drugs with a very dynamic development. Ruxolitinib, an oral selective inhibitor of JAK1 and JAK2 kinases, has shown high efficacy in patients with high-risk PMF (or with myelofibrosis following polycythemia vera or essential thrombocythemia) to ameliorate disease symptoms and to reduce splenomegaly in randomized trials COMFORT-I and COMFORT-II. Long-term monitoring of the enrolled patients demonstated prolongation of overall survival. The drug is well-tolerated, the most common side effects of treatment with ruxolitinib being deepening of thrombocytopenia and temporary worsening of anemia. The current review deals with the place of JAK2 inhibitors (and the only drug already approved for clinical use - ruxolitinib) in the management of PMF, as an addendum to the Summary of recommendations for the diagnosis and therapy of BCR/ABL-negative myeloproliferations of the Czech Hematological Societys CZEMP.

    Chronic pain in childhood and adolescence has been shown to heighten the risk for depressive and anxiety disorders in specific samples in adulthood; however, little is known about the association between a wider variety of chronic pains and internalizing mental health disorders. Using nationally representative data, the objectives of this study were to establish prevalence rates of internalizing mental health disorders (anxiety and depressive disorders) among cohorts with or without adolescent chronic pain, and to examine whether chronic pain in adolescence is associated with lifetime history of internalizing mental health disorders reported in adulthood. Data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) was used (N = 14,790). Individuals who had chronic pain in adolescence subsequently reported higher rates of lifetime anxiety disorders (21.1% vs 12.4%) and depressive disorders (24.5% vs 14.1%) in adulthood as compared with individuals without a history of adolescent chronic pain. Multivariate logistic regression confirmed that chronic pain in adolescence was associated with an increased likelihood of lifetime history of anxiety disorders (odds ratio: 1.33; 95% confidence interval: 1.09-1.63, P = 0.005) and depressive disorders (odds ratio: 1.38; confidence interval: 1.16-1.64, P < 0.001) reported in adulthood. Future research is needed to examine neurobiological and psychological mechanisms underlying these comorbidities.

    Dysregulated iron homeostasis plays a central role in the development of anemia of chronic kidney disease (CKD) and is a major contributor toward resistance to treatment with erythropoiesis-stimulating agents. Understanding the underlying pathophysiology requires an in-depth understanding of normal iron physiology and regulation. Recent discoveries in the field of iron biology have greatly improved our understanding of the hormonal regulation of iron trafficking in human beings and how its alterations lead to the development of anemia of CKD. In addition, emerging evidence has suggested that iron homeostasis interacts with bone and mineral metabolism on multiple levels, opening up new avenues of investigation into the genesis of disordered iron metabolism in CKD. Building on recent advances in our understanding of normal iron physiology and abnormalities in iron homeostasis in CKD, this review characterizes how anemia related to disordered iron metabolism develops in the setting of CKD. In addition, this review explores our emerging recognition of the connections between iron homeostasis and mineral metabolism and their implications for the management of altered iron status and anemia of CKD.

    Transient signal changes in the pulvinar have been described following status epilepticus. However, we observed persistent thalamus changes after seizures. The purpose of this study was to characterize thalamus changes in patients with seizure disorders and to correlate imaging findings with clinical features. We searched among 5,500 magnetic resonance imaging (MRI) exams performed in patients with seizures and identified 43 patients. The MRI scans of these patients were reviewed and correlated with clinical data. We identified four patterns of thalamus lesions: (a) fluid attenuated inversion recovery-hyperintense pulvinar lesions (20 patients), as known from status epilepticus. Ten patients in this group had a status epilepticus. Among the remaining patients, three had frequent seizures and seven had sporadic seizures. Twelve patients had follow-up exams for a median of 11 months. The lesions had persisted in 11/12 cases in the last available exam and were reversible in one case only. In seven cases, cone-shaped thalamus atrophy resulted, (b) linear defects in the medial and anterior thalamus (five patients), accompanied by atrophy of the mamillary body and the fornix in patients with chronic epilepsy, (c) extensive bilateral thalamus lesions in two patients with a syndrome caused by mutation in the mitochondrial polymerase gamma, and (d) other thalamus lesions not associated with the seizure disorder (16 patients). The spectrum of thalamus lesions in patients with seizure disorders is wider than previously reported. Postictal pulvinar lesions can persist and may result in thalamic atrophy. Linear defects in the anterior thalamus are associated with limbic system atrophy. (orig.)

In recent years, research has sought to determine if there is a co-occurrence between COPD and posttraumatic stress disorder (PTSD as well as for associations between PTSD and COPD-related outcomes. To date, there have been no published reviews summarizing this emerging literature.Objectives: The primary objective of this review was to determine if there is adequate evidence to support a co-occurrence between PTSD and COPD. Secondary objectives were to: 1 determine if there are important clinical considerations regarding the impact of PTSD on COPD management, and 2 identify targeted areas for further research.Methods: A structured review was performed using a systematic search strategy limited to studies in English, addressing adults, and to articles that examined: 1 the co-occurrence of COPD and PTSD and 2 the impact of PTSD on COPD-related outcomes. To be included, articles must have addressed some type of nonreversible obstructive lung pathology.Results: A total of 598 articles were identified for initial review. Upon applying the inclusion and exclusion criteria, n=19 articles or abstracts addressed our stated objectives. Overall, there is inconclusive evidence to support the co-occurrence between PTSD and COPD. Studies finding a significant co-occurrence generally had inferior methods of identifying COPD; in contrast, studies that utilized more robust COPD

    Ever since their description as "myeloproliferative syndromes" by William Dameshek in 1951, the myeloproliferative neoplasms (MPNs) have been managed by the selective use of rather mundane, nonspecific therapies that rely on either antiplatelet effects or myelosuppression. The year 2005 ushered in a new era of drug development and discovery for the MPNs after the description of the JAK2 V617F mutation and the role this constitutively active tyrosine kinase has in MPN pathogenesis. Subsequently, multiple pharmacologic agents have begun (or are about to begin) testing for the inhibition of JAK2 in an attempt to improve the treatment of MPNs. Both primary myelofibrosis and myelofibrosis following essential thrombocythemia or polycythemia vera have been the targets of the most extensive testing of these agents to date. Responses to these oral JAK2 inhibitors have been primarily intended to reduce splenomegaly and meaningfully improve symptoms; effects on the JAK2 V617F allele burden or marrow histology are limited. Toxicities have ranged from myelosuppression to significant diarrhea. Additional agents with other mechanisms of action are also targeting JAK2, including histone deacetylase inhibitors and mTOR inhibitors. The results of preliminary trials of JAK2 inhibitors in polycythemia vera and essential thrombocythemia have been mixed but are premature. Many questions remain as to the optimal JAK2 inhibitory strategy and the full extent of the benefit of single-agent JAK2 inhibition.

    Full Text Available Background: Disturbances of microcirculation play a significant role in the development and progression of both acute and chronic cerebrovascular diseases (CVD and may be associated with different hemogram abnormalities. One of the reasons of the prothrombogenic state of the endothelium is the increase in the number of blood corpuscles leading to (non-Ph myeloproliferative disorders (MPD including essential thrombocythemia (ET, polycythemia vera (PV, and primary myelofibrosis (PM. Materials and Methods: The study included 167 patients: 102 patients with Ph-MPD and the control group comprising 65 patients with CVD. According to MPD subtype, the patients were divided into three groups: patients with ET (37%, n = 38, male/female 7/31, age 52 ± 7 years, those with PV (40%, n = 41, male/female 20/21, age 50 ± 6 years and those with PM (23%, n = 23, male/female 5/18, age 54 ± 4 years. Results: In 79% (n = 81 of cases in the study group (with Ph-MPD, patients had chronic CVD, with the most frequently identified symptoms being asthenia (92% and headache (72%. Headache in Ph-MPD patients was more frequently (86% associated with PM, while in patients with PV and ET it was equally distributed (70%. Neurological symptoms in 53% of cases were associated with focal changes of the brain on MRI localized in the subcortical area of the frontal and parietal lobes. Twenty-one (21% patients suffered an acute cerebrovascular accident, 8 of them had thrombotic occlusion of one of the internal carotid arteries leading to hemispheric infarcts.

    Inflammatory joint disorders (IJD), including rheumatoid arthritis (RA), ankylosing spondylitis (ASp) and psoriatic arthritis (PsA), are prevalent conditions worldwide with a considerable burden on healthcare systems. IJD are associated with increased cardiovascular (CV) disease-related morbidity and mortality. In this review, we present an overview of the literature. Standardised mortality ratios are increased in IJD compared with the general population, that is, RA 1.3-2.3, ASp 1.6-1.9 and PsA 0.8-1.6. This premature mortality is mainly caused by atherosclerotic events. In RA, this CV risk is comparable to that in type 2 diabetes. Traditional CV risk factors are more often present and partially a consequence of changes in physical function related to the underlying IJD. Also, chronic systemic inflammation itself is an independent CV risk factor. Optimal control of disease activity with conventional synthetic, targeted synthetic and biological disease-modifying antirheumatic drugs decreases this excess risk. High-grade inflammation as well as anti-inflammatory treatment alter traditional CV risk factors, such as lipids. In view of the above-mentioned CV burden in patients with IJD, CV risk management is necessary. Presently, this CV risk management is still lacking in usual care. Patients, general practitioners, cardiologists, internists and rheumatologists need to be aware of the substantially increased CV risk in IJD and should make a combined effort to timely initiate CV risk management in accordance with prevailing guidelines together with optimal control of rheumatic disease activity. CV screening and treatment strategies need to be implemented in usual care.

PATIENTS: Eighteen patients with chronic myelogenous leukemia (CML, 5 with polycytemia vera (PV, 2 with essential thrombocytemia (ET and 2 with idiopathic myelofibrosis (MF. Duke's BT and epinephrine-induced platelet aggregation were performed on the patients and on 10 healthy individuals. RESULTS: Eleven patients presented symptoms (41 %: 9 with hemorrhage (33% and 5 with thrombosis (19%.There were less symptomatic patients in the CML group (28% than in the other MPD (67%, without statistical significance (Fisher, p=0.06. Duke's BT was longer in symptomatic patients (Mann-Whitney, p<0.05. Platelet aggregation was abnormal in 7 patients (26% and 71% of them were symptomatic (Fisher, p = 0.07. CONCLUSIONS: The high incidence of bleeding and thrombosis in patients with MPD was related to prolonged BT, but not to platelet aggregation abnormalities.

    Myeloproliferative neoplasms (essential thrombocythemia, ET; polycythemia vera, PV; myelofibrosis, MF) are monoclonal malignancies associated with genomic instability, dysregulated signaling pathways, and subsequent overproduction of inflammatory markers. Acknowledged for their debilitating symptom profiles, recent investigations have aimed to determine the identity of these markers, the upstream sources stimulating their development, their prevalence within the MPN population, and the role they play in symptom development. Creation of dedicated Patient Reported Outcome (PRO) tools, in combination with expanded access to cytokine analysis technology, has resulted in a surge of investigations evaluating the potential associations between symptoms and inflammation. Emerging data demonstrates clear relationships between individual MPN symptoms (fatigue, abdominal complaints, microvascular symptoms, and constitutional symptoms) and cytokines, particularly IL-1, IL-6, IL-8, and TNF-α. Information is also compiling on the role symptoms paradoxically play in the development of cytokines, as in the case of fatigue-driven sedentary lifestyles. In this paper, we explore the symptoms inherent to the MPN disorders and the potential role inflammation plays in their development.

  15. Defining the Thrombotic Risk in Patients with Myeloproliferative Neoplasms

    Directory of Open Access Journals (Sweden)

    Fabrizio Vianello

    2011-01-01

    Full Text Available Polycythemia vera (PV and essential thrombocythemia (ET are two Philadelphia-negative myeloproliferative neoplasms (MPN associated with an acquired mutation in the JAK2 tyrosine kinase gene. There is a rare incidence of progression to myelofibrosis and myeloid metaplasia in both disorders, which may or may not precede transformation to acute myeloid leukemia, but thrombosis is the main cause of morbidity and mortality. The pathophysiology of thrombosis in patients with MPN is complex. Traditionally, abnormalities of platelet number and function have been claimed as the main players, but increased dynamic interactions between platelets, leukocytes, and the endothelium do probably represent a fundamental interplay in generating a thrombophilic state. In addition, endothelial dysfunction, a well-known risk factor for vascular disease, may play a role in the thrombotic risk of patients with PV and ET. The identification of plasma markers translating the hemostatic imbalance in patients with PV and ET would be extremely helpful in order to define the subgroup of patients with a significant clinical risk of thrombosis.

    Full Text Available Myeloproliferative neoplasms are clonal diseases of hematopoietic stem cells characterized by myeloid hyperplasia and increased risk of developing acute myeloid leukemia. Myeloproliferative neoplasms are caused, as any other malignancy, by genetic defects that culminate in the neoplastic phenotype. In the past six years, since the identification of JAK2V617F, we have experienced a substantial increase in our knowledge about the genetic mechanisms involved in the genesis of myeloproliferative neoplasms. Mutations described in several genes have revealed a considerable degree of molecular homogeneity between different subtypes of myeloproliferative neoplasms. At the same time, the molecular differences between each subtype have become clearer. While mutations in several genes, such as JAK2, myeloproliferative leukemia (MPL and LNK have been validated in functional assays or animal models as causative mutations, the roles of other recurring mutations in the development of disease, such as TET2 and ASXL1 remain to be elucidated. In this review we will examine the most prevalent recurring gene mutations found in myeloproliferative neoplasms and their molecular consequences.

    Full Text Available Chronic stress-related psychiatric diseases, such as major depression, posttraumatic stress disorder, and schizophrenia, are characterized by a maladaptive organization of behavioral responses that strongly affect the well-being of patients. Current evidence suggests that a functional impairment of the prefrontal cortex (PFC is implicated in the pathophysiology of these diseases. Therefore, chronic stress may impair PFC functions required for the adaptive orchestration of behavioral responses. In the present review, we integrate evidence obtained from cognitive neuroscience with neurophysiological research with animal models, to put forward a hypothesis that addresses stress-induced behavioral dysfunctions observed in stress-related neuropsychiatric disorders. We propose that chronic stress impairs mechanisms involved in neuronal functional connectivity in the PFC that are required for the formation of adaptive representations for the execution of adaptive behavioral responses. These considerations could be particularly relevant for understanding the pathophysiology of chronic stress-related neuropsychiatric disorders.

    2015-09-01

    Chronic cough is a frequent reason for medical referrals in childhood. In patients who do not have signs or symptoms of an underlying respiratory system disease and who do not respond to experimental treatment, psychogenic cough should be considered. In this paper, four patients who were referred to our department with a prediagnosis of psychogenic cough, found to have tic disorder as a result of the assessments performed and improved with antipsychotic medication are presented. The differantial diagnosis of chronic cough in children should include tic disorders as well as psychogenic cough. Tic disorders can be diagnosed easily with detailed history and their response to medical treatment is rather satisfactory. Recognition of these disorders by pediatricians will minimize erroneous diagnoses and inappropriate therapies in children with a complaint of chronic cough.

    Chronic pain is common in HIV, but incompletely characterized, including its underlying etiologies, its effect on healthcare utilization, and the characteristics of affected patients in the HIV primary care setting. These data are needed to design and justify appropriate clinic-based pain management services. Using a clinical data warehouse, we analyzed one year of data from 638 patients receiving standard-of-care antiretroviral therapy in a large primary care HIV clinic, located in the Harlem neighborhood of New York City. We found that 40% of patients carried one or more chronic pain diagnoses. The most common diagnoses were degenerative musculoskeletal disorders (eg, degenerative spinal disease and osteoarthritis), followed by neuropathic pain and headache disorders. Many patients (16%) had multiple chronic pain diagnoses. Women, older patients, and patients with greater burdens of medical illness, and psychiatric and substance use comorbidities were disproportionately represented among those with chronic pain diagnoses. Controlling for overall health status, HIV patients with chronic pain had greater healthcare utilization including emergency department visits and radiology procedures. In summary, our study demonstrates the high prevalence of chronic pain disorders in the primary care HIV clinic. Colocated interventions for chronic pain in this setting should not only focus on musculoskeletal pain but also account for complex multifaceted pain syndromes, and address the unique biopsychosocial features of this population. Furthermore, because chronic pain is prevalent in HIV and associated with increased healthcare utilization, developing clinic-based pain management programs could be cost-effective.

    Chronic recurrent multifocal osteomyelitis (CRMO) is a rare non-infectious inflammatory bone disease of unknown aetiology. CRMO mainly affects the metaphyses of long bones and spine in children and young adolescents. It presents with recurrent episodes of bone pain and fever, resembling bacterial osteomyelitis, but cultures of lesions are sterile and it is unresponsive to antibiotic therapy. We report a case of a 3-year-old boy diagnosed with CRMO, who was initially treated for bacterial osteomyelitis, and received prolonged antibiotic therapy for chronic pain, and swelling of mandible and ulna. CRMO should be kept in mind in the differential diagnosis of chronic bone pain and osteomyelitis unresponsive to antibiotic treatment.

    Pelletier, René; Higgins, Johanne; Bourbonnais, Daniel

    2015-11-01

    Present interventions utilized in musculoskeletal rehabilitation are guided, in large part, by a biomedical model where peripheral structural injury is believed to be the sole driver of the disorder. There are, however, neurophysiological changes across different areas of the peripheral and central nervous systems, including peripheral receptors, dorsal horn of the spinal cord, brain stem, sensorimotor cortical areas, and the mesolimbic and prefrontal areas associated with chronic musculoskeletal disorders, including chronic low back pain, osteoarthritis, and tendon injuries. These neurophysiological changes appear not only to be a consequence of peripheral structural injury but also to play a part in the pathophysiology of chronic musculoskeletal disorders. Neurophysiological changes are consistent with a biopsychosocial formulation reflecting the underlying mechanisms associated with sensory and motor findings, psychological traits, and perceptual changes associated with chronic musculoskeletal conditions. These changes, therefore, have important implications in the clinical manifestation, pathophysiology, and treatment of chronic musculoskeletal disorders. Musculoskeletal rehabilitation professionals have at their disposal tools to address these neuroplastic changes, including top-down cognitive-based interventions (eg, education, cognitive-behavioral therapy, mindfulness meditation, motor imagery) and bottom-up physical interventions (eg, motor learning, peripheral sensory stimulation, manual therapy) that induce neuroplastic changes across distributed areas of the nervous system and affect outcomes in patients with chronic musculoskeletal disorders. Furthermore, novel approaches such as the use of transcranial direct current stimulation and repetitive transcranial magnetic stimulation may be utilized to help renormalize neurological function. Comprehensive treatment addressing peripheral structural injury as well as neurophysiological changes occurring across

    Aim: In this study, it was aimed to evaluate the quality of life and self-esteem in children and adolescents with Tourette syndrome (TS) and other chronic motor or vocal tic disorders in comparison with the control group. This is the first study examining the effects of quality of life and self-esteem on each other in chronic tic disorders. Material and Methods: Among 62 patients aged between 6 and 16 years who were diagnosed with chronic tic disorder according to the Diagnostic and Statistical Manual of Mental Disorders-IV, 57 patients who met the study inclusion criteria constituted the study group and 57 age- and gender-matched individuals constituted the control group (Ethics committee file number: 2009/69; ethics committee meeting number: 2009/14 (11.06.2009); ethics committee decision number: 16). The Rosenberg self-esteem scale, Pediatric Quality of Life Inventory, Children’s Depression Inventory, Screen for Child Anxiety Related Disorders, Maudsley Obsessional Compulsive Inventory and the Schedule for Affective Disorders and Schizophrenia-Present and Lifetime version were applied to the children and adolescents. Results: In the study group, all quality of life subtests were found to be lower compared to the control group both in children and adolescents except for self-reported emotional functionality and social functionality. Being below the age of 12 years and female gender were found to be predictors of low self-esteem in tic disorder. In the reports obtained from the children and adolescents, low self-esteem was related with decreased quality of life in all areas except for academic functionality. Conclusions: Children and adolescents with tic disorder experience functional disruption with a higher rate compared to the group without a psychiatric disorder or severe medical condition. Applying holistic approaches considering other clinical psychiatric symptoms as a part of chronic tic disorder will be useful in increasing the quality of life and self

    Objective: To determine prevalence of depression in chronic respiratory disorders in a tertiary rural hospital of Central India. Various studies done in past have shown that prevalence of depression in diabetes and hypertension is around 40%-57%. Few studies have been done to screen depression in chronic respiratory disorders. This study was conducted in a tertiary rural hospital of Central India to find out prevalence of depression in indoor patients suffering from chronic respiratory disorders. Methods: Total 68 patients were evaluated for depression. Patients suffering from chronic respiratory disorders (total duration of illness >3 months) were evaluated using Prime MD Questionnaire. Patients suffering from diabetes, heart diseases, stroke, having past history of psychiatric illness, drug abusers, having lack of social support and suffering from chronic upper respiratory tract infections were excluded from this study. Questionnaire was asked when treatment for acute phase of illness is over. Results: Out of 68 patients evaluated, 36 (53%) were found out to be suffering from depression. Female gender (80%) was more prone to depression, inspite of the fact that all alcoholics were male. 39% of all chronic obstructive pulmonary disease (COPD) patients were suffering from depression in comparison to 65% for pulmonary tuberculosis and 44% for other chronic respiratory illness. 54% of patients suffering from depression are 60 yrs of age, suggesting that age has no relation with depression. No association was seen between alcoholism and depression. Conclusion: Prevalence of depression in patients of chronic respiratory illness is very high, like in cases of diabetes and hypertension. Further community and hospital based studies are needed to find out exact prevalence of depression in chronic respiratory illnesses.

    Systemic immunity was studied in patients with chronic generalized parodontitis. This group of patients had distinct changes in immunologic system: depression of T- and stimulation of B-cellular immunity without accumulation of plasma cells and initiation of effective humoral response. Increased peripheral blood number of lymphocytes expressing induction of apoptosis CD95 receptors and ligand for this receptor CD95L (Fas-L) can lead to intensification of lymphocyte apoptosis and may be the reason for T-cell deficit development. The results of the study confirm the important role of immune system disturbances in pathogenesis of chronic generalized parodontitis.

    Chronic kidney disease (CKD) alters the metabolism of several minerals, thereby inducing bone lesions and vessel-wall calcifications that can cause functional impairments and excess mortality. The histological bone abnormalities seen in CKD, known as renal osteodystrophy, consist of alterations in the bone turnover rate, which may be increased (osteitis fibrosa [OF]) or severely decreased (adynamic bone disease [AD]); abnormal mineralization (osteomalacia [OM]), and bone loss. Secondary hyperparathyroidism is related to early phosphate accumulation (responsible for FGF23 overproduction by bone tissue), decreased calcitriol production by the kidneys, and hypocalcemia. Secondary hyperparathyroidism is associated with OF. Other factors that affect bone include acidosis, chronic inflammation, nutritional deficiencies, and iatrogenic complications.

    BACKGROUND Somatic mutations in the Janus kinase 2 gene (JAK2) occur in many myeloproliferative neoplasms, but the molecular pathogenesis of myeloproliferative neoplasms with nonmutated JAK2 is obscure, and the diagnosis of these neoplasms remains a challenge. METHODS We performed exome sequencing of samples obtained from 151 patients with myeloproliferative neoplasms. The mutation status of the gene encoding calreticulin (CALR) was assessed in an additional 1345 hematologic cancers, 1517 other cancers, and 550 controls. We established phylogenetic trees using hematopoietic colonies. We assessed calreticulin subcellular localization using immunofluorescence and flow cytometry. RESULTS Exome sequencing identified 1498 mutations in 151 patients, with medians of 6.5, 6.5, and 13.0 mutations per patient in samples of polycythemia vera, essential thrombocythemia, and myelofibrosis, respectively. Somatic CALR mutations were found in 70 to 84% of samples of myeloproliferative neoplasms with nonmutated JAK2, in 8% of myelodysplasia samples, in occasional samples of other myeloid cancers, and in none of the other cancers. A total of 148 CALR mutations were identified with 19 distinct variants. Mutations were located in exon 9 and generated a +1 base-pair frameshift, which would result in a mutant protein with a novel C-terminal. Mutant calreticulin was observed in the endoplasmic reticulum without increased cell-surface or Golgi accumulation. Patients with myeloproliferative neoplasms carrying CALR mutations presented with higher platelet counts and lower hemoglobin levels than patients with mutated JAK2. Mutation of CALR was detected in hematopoietic stem and progenitor cells. Clonal analyses showed CALR mutations in the earliest phylogenetic node, a finding consistent with its role as an initiating mutation in some patients. CONCLUSIONS Somatic mutations in the endoplasmic reticulum chaperone CALR were found in a majority of patients with myeloproliferative neoplasms with

    Chronic eosinophilic leukemia (CEL) is a very rare form of leucemia in the western world. Adequate response is seldomly achieved after treatment with corticosteroids, interferon-alfa (INF-alfa) and medications containing hydroxi-urea (Litalir). The study presents a patient with CEL with no initial therapeutic response to the use of corticosteroids, INF-alfa and hydroxy-urea, and with neither clinical nor hematological response. After setting a diagnosis of CEL, patient was ordinated Imatinib (Glivec tabbletes) in a daily dose of 200 mg. Two days afterwards there was an evident withdrawal of subjective and clinical symptoms of disease, and the complete blood count showed significant amendment.

    The article presents data on peculiarities of chronic pancreatitis course in railway transport workers (engine operators, engine operator assistants, dispatchers) with anxious depressive disorders. Pain and dyspepsia in patients with affective disorders appeared to be constant and more intense than in the patients without concomitant anxious depression. Psychophysiologic tests in 83% of patients with comorbid conditions revealed significant psychomotor dullness manifested in reliable lower speed of visual motor reactions. Pharmacologic correction via anxiolytics (Adaptol, Afobasol) combined with standard therapy for chronic pancreatitis exacerbation enabled to improve clinical symptoms, but Adaptol appeared to slow simple visual motor reactions, therefore has to be ruled out in engine operators. Pharmacotherapy of chronic pancreatitis, that included Afobasol in addition to standard treatment, promoted reliable improvement of occupationally important psychophysiologic functions. This study received a patent.

    Chronic Obstructive Pulmonary Disease (COPD) is a chronic inflammatory lung disease which may be complicated by development of co-morbidities including metabolic disorders. Metabolic disorders commonly associated with this disease contribute to lung function impairment and mortality. Systemic inflammation appears to be a major factor linking COPD to metabolic alterations. Adipose tissue seems to interfere with systemic inflammation in COPD patients by producing a large number of proteins, known as "adipokines", involved in various processes such as metabolism, immunity and inflammation. There is evidence that adiponectin is an important modulator of inflammatory processes implicated in airway pathophysiology. Increased serum levels of adiponectin and expression of its receptors on lung tissues of COPD patients have recently highlighted the importance of the adiponectin pathway in this disease. Further, in vitro studies have demonstrated an anti-inflammatory activity for this adipokine at the level of lung epithelium. This review focuses on mechanisms by which adiponectin is implicated in linking COPD with metabolic disorders.

    Full Text Available Observation of cardiologists and psychiatrists suggest that cardiovascular diseases and depression are the most common and frequent comorbid conditions. Therefore the aim of the study was to identify behavioral disorders in rats on the background of myocardial dysfunction in the experiment. Material of the research: 60 adult male rats of Wistar line, weighing 200-220 g, divided into 2 groups - control and experimental. Myocardial dysfunction was modeled by intraperitoneal injection of doxorubicin by 5 mg/kg of animal weight. To verify the model of myocardial dysfunction ECG and histological examination of the myocardium were performed. Evaluation of higher divisions of the CNS reactions was performed using the "open field" method by such indicators: vertical and horizontal motor activity (decreased by 71,4%, acts and defecation boluses (down by 85-88%, the number of burrows (decreased by 57-90%, grooming (decreased by 23%, all parameters were reliable (in p<0,05. There was a gradual decline of rats’ emotionality, CNS depression and increased anxiety. It was found that behavioral disorders in the experiment were typical for anxiety and depression states.

    Sleep disturbances (SD) are a frequent finding in patients with asthma and chronic obstructive pulmonary disease (COPD) and have a negative impact on quality of life and the clinical course of the disease. The causes of SD are multiple and include for example respiratory symptoms and comorbidities. On the other hand sleep goes along with multiple physiological changes in respiration, so that sleep itself interacts with asthma and COPD. This interaction favors respiratory symptoms and may lead to hypoxemia and hypercapnia. A further complication of the respiratory situation and the clinical course can be found in asthma and COPD patients with coexisting obstructive sleep apnea syndrome (OSAS). Due to the heterogeneity of SD in asthma and COPD, a detailed patient survey is the most important diagnostical tool. Based on the survey further technical examinations should be considered. Treatment strategies for the reduction of SD in asthma and COPD include an optimized medication and treatment of comorbidities. If indicated oxygen therapy, positive pressure breathing and pulmonary rehabilitation can contribute.

    The aim of this study was to confirm a fact known in the relevant literature that there is a correlation between static anomalies of the sole, and varicose veins, a consequence of the decreased quality of the conjunctive tissue. We cite genetic and dynamic factors by way of explanation. To confirm the fact that deformities of the sole of the foot are linked with chronic venous incompetence and influence the functional capacity of the muscular pump, the authors have analysed in young subjects the contractile capacity of the pump even when the index of reduction in the sole of the foot was quite low. The muscular pump in the calf is a compensatory system from the point of view of functional capacity. The authors noted that the velocimetric parameter of speed of flux in the femoral vein is a sensitive parameter and changes rapidly, rising with even minimal activity in the calf. The authors think that acquired deformities are one of the most frequent causes of the poor functioning of the muscular pump in the calf.

    Full Text Available Background and aims: Depression and cognitive disorders were reported more frequently in patients with diabetes mellitus (DM. Our aim was to analyze the association of cognitive disorders and depression association with chronic complications of DM in a group of Romanian patients. Materials and methods: The data was analyzed from 181 patients, with a mean age of 58,3 years to whom we applied the MMSE (Mini- Mental State Examination and MADRS (Montgomery-Asberg Depression Rating Scale questionnaires. We also analyzed the presence of chronic DM complications, HbA1c and lipid profile. Results: Most patients with type 2 diabetes mellitus (T2DM had mild cognitive impairment (92%, more common in the age group 50-59 years. Chronic macrovascular complications were present in 74.58%, while chronic microvascular complications were present in 61.87% of patients with T2DM who associated mild and moderate cognitive impairment (p = 0.013. The most common form of depression was mild depression (90.2%, present in most patients with DM, regardless of progression and type of treatment. MADRS depression test scores were statistically significant correlated with the presence of peripheral artery disease - PAD (p <0.001, ischemic heart disease - IHD (p <0.001 and chronic kidney disease - CKD (p =0.05. We did not find a statistically significant correlation with HbA1c and serum lipid values (p˃0,05. Conclusion: Chronic diabetes macrovascular complications (PAD, IHD and CKD were more frequently associated with cognitive disorders and depression in patients with T2DM independent of the degree of metabolic control.

    A proposal for the inclusion of complex posttraumatic stress disorder (CPTSD) in the upcoming ICD-11 has been put forward. Using self-report, we investigated the resemblance between disorders of extreme stress not otherwise specified (DESNOS) and both axis I and II syndromes among 116 treatment-seeking Bosnian refugees. In this sample, the prevalence of DESNOS overlapped to a large degree with the prevalence of schizotypal and paranoid personality disorders (PDs). There was, however, also a large prevalence of axis I syndromes in the group. Thus, DESNOS in the refugees can be categorized as an axis I or II disorder depending on the chronicity and the severity of functional impairment. DESNOS and PD-like states were even observed among the refugees with no history of childhood maltreatment. No large differences were observed between DESNOS and PD regarding sex. The symptom constellation of CPTSD in the ICD-11 is partially supported. However, CPTSD might resemble PD to a considerable degree.

  20. Chronic granulomatous disease: lessons from a rare disorder.

    2011-01-01

    Chronic granulomatous disease (CGD) is a rare primary immunodeficiency with X-linked or autosomal recessive inheritance involving defects in genes encoding phox proteins, which are the subunits of the phagocyte NADPH oxidase. This results in failure to produce superoxide anion and downstream antimicrobial oxidant metabolites and to activate antimicrobial proteases. Affected patients are susceptible to severe, life-threatening bacterial and fungal infections and excessive inflammation characterized by granulomatous enteritis resembling Crohn's disease and genitourinary obstruction. Early diagnosis of CGD and rapid treatment of infections are critical. Prophylaxis with antibacterial and mold-active antifungal agents and the administration of interferon-γ has significantly improved the natural history of CGD. Currently, the only cure is allogeneic hematopoietic cell transplant (HCT), although there remains controversy as to which patients with CGD should get a transplant. Allele-based HLA typing of alternative donors, improved supportive care measures, and use of reduced toxicity conditioning have resulted in event-free survival (EFS) of at least 80% even with an unrelated donor and even better when the patient has no active infections/inflammation. Gene correction of CGD would eliminate the risks of graft-versus-host disease (GVHD) and the immunoablative chemotherapy required for allogeneic HCT. Based on gene therapy trials in patients with SCID-X1, ADA-SCID, and the early experience with CGD, it is clear that at least some degree of myeloablation will be necessary for CGD as there is no inherent selective growth advantage for gene-corrected cells. Current efforts for gene therapy focus on use of lentivector constructs, which are thought to be safer from the standpoint of insertional mutagenesis and more efficient in transducing hematopoietic stem cells (HSCs).

    Insomnia is a pervasive problem for many patients suffering from medical and psychiatric conditions. Even when the comorbid disorders are successfully treated, insomnia often fails to remit. In addition to compromising quality of life, untreated insomnia may also aggravate and complicate recovery from the comorbid disease. Cognitive behavior therapy for insomnia (CBT-I) has an established efficacy for primary insomnia, but less is known about its efficacy for insomnia occurring in the context of medical and psychiatric conditions. The purpose of this article is to present a rationale for using CBT-I in medical and psychiatric disorders, review the extant outcome literature, highlight considerations for adapting CBT-I procedures in specific populations, and suggest directions for future research. Outcome studies were identified for CBT-I in mixed medical and psychiatric conditions, cancer, chronic pain, HIV, depression, posttraumatic stress disorder, and alcoholism. Other disorders discussed include: bipolar disorder, eating disorders, generalized anxiety, and obsessive compulsive disorder. The available data demonstrate moderate to large treatment effects (Cohen's d, range=0.35-2.2) and indicate that CBT-I is a promising treatment for individuals with medical and psychiatric comorbidity. Although the literature reviewed here is limited by a paucity of randomized, controlled studies, the available data suggest that by improving sleep, CBT-I might also indirectly improve medical and psychological endpoints. This review underscores the need for future research to test the efficacy of adaptations of CBT-I to disease specific conditions and symptoms.

    The last 25 years have been characterized by dramatic improvements in short-term patient and allograft survival after kidney transplantation. Long-term patient and allograft survival remains limited by cardiovascular disease and chronic allograft injury, among other factors. Cardiovascular disease remains a significant contributor to mortality in native chronic kidney disease as well as cardiovascular mortality in chronic kidney disease more than doubles that of the general population. The chronic kidney disease (CKD)-mineral bone disorder (MBD) is a syndrome recently coined to embody the biochemical, skeletal, and cardiovascular pathophysiology that results from disrupting the complex systems biology between the kidney, skeleton, and cardiovascular system in native and transplant kidney disease. The CKD-MBD is a unique kidney disease-specific syndrome containing novel cardiovascular risk factors, with an impact reaching far beyond traditional notions of renal osteodystrophy and hyperparathyroidism. This overview reviews current knowledge of the pathophysiology of the CKD-MBD, including emerging concepts surrounding the importance of circulating pathogenic factors released from the injured kidney that directly cause cardiovascular disease in native and transplant chronic kidney disease, with potential application to mechanisms of chronic allograft injury and vasculopathy.

    PURPOSE: The purpose of this paper was to review the literature concerning the treatment of chronic kidney disease-mineral bone disorder (CKD-MBD) in the elderly peritoneal dialysis (PD) patient. ♦ RESULTS: Chronic kidney disease-mineral bone disorder is a major problem in the elderly PD patient......, with its associated increased fracture risk, vascular calcification, and accelerated mortality fracture risk. Peritoneal dialysis, however, bears a lower risk than hemodialysis (HD). The approach to CKD-MBD prophylaxis and treatment in the elderly PD patient is similar to other CKD patients, with some...... important differences. Avoidance of hypercalcemia, hyperphosphatemia, and hyperparathyroidism is important, as in other CKD groups, and is generally easier to attain. Calcium-free phosphate binders are recommended for normocalcemic and hypercalcemic patients. Normalization of vitamin D levels to > 75 nmol...

    2016-01-01

    We describe a 59-year-old female who presented with ischaemic digits, preceded by a 6-month history of Raynaud's phenomenon affecting her fingers and toes. There were no clinical or laboratory features of primary vasculitis or connective tissue disease, Doppler imaging was normal, and bloods were unremarkable aside from a platelet count of 786 × 109/L (150-400) and white cells of 16 × 109/L (4-11). In view of the thrombocytosis a JAK2 mutation assay was requested which confirmed a JAK2 V617F mutation, suggesting essential thrombocytosis (ET) as the cause. She received treatment with hydroxycarbamide which normalised her platelet count and led to a complete resolution of her Raynaud's symptoms. Raynaud's phenomenon is a rare manifestation of ET. Myeloproliferative disorders such as ET should be considered in the differential diagnosis of Raynaud's phenomenon and vasculitis.

    2006-02-01

    Chronic neck pain, a common cause of disability, seems to be the result of several interacting mechanisms. In addition to degenerative and inflammatory changes and trauma, psychological and psychosocial factors are also involved. One common type of trauma associated with chronic neck pain is whiplash injury; this sometimes results in whiplash-associated disorder (WAD), a controversial condition with largely unknown pathogenetic mechanisms. We studied the prevalence of chronic neck pain of traumatic and non-traumatic origin and compared the prevalence of, sociodemographic data, self-perceived health, workload and chronic low-back pain in these groups. In a ready-made questionnaire (MONICA study), we added questions about cervical spine and low-back complaints. 6,000 (72%) completed a self-administered questionnaire. 43% reported neck pain: 48% of women and 38% of men. Women of working age had more neck pain than retired women, a phenomenon not seen in men. 19% of the studied population suffered from chronic neck pain and it was more frequent in women. A history of neck trauma was common in those with chronic neck pain. Those with a history of neck trauma perceived their health worse and were more often on sick-leave. About 50% of those with traumatic and non-traumatic chronic neck pain also had chronic low-back pain. We assessed the subjective and objective neuropsychological functioning in 42 patients with chronic neck pain, 21 with a whiplash trauma, and 21 without previous neck trauma. Despite cognitive complaints, the WAD patients had normal neuropsychological functioning, but the WAD group especially had deviant MMPI results-indicating impaired coping ability and somatization. WAD patients had no alterations in cerebral blood-flow pattern, as measured by rCBF-SPECT and SPM analysis, compared to healthy controls. This contrasts with the non-traumatic group with chronic neck pain, which showed marked blood-flow changes. The blood-flow changes in the non

    This study investigated the effects of (-)-sesamin on chronic electric footshock (EF) stress-induced anxiety disorders in mice. Mice were treated with (-)-sesamin (25 and 50 mg/kg) orally once a day for 21 days prior to exposure to EF stress (0.6 mA, 1 s every 5 s, 3 min). Mice treated with (-)-sesamin (25 and 50 mg/kg) exhibited less severe decreases in the number of open arm entries and time spent on open arms in the elevated plus-maze test and the distance traveled in the open field test following exposure to chronic EF stress. Similarly, mice treated with (-)-sesamin exhibited significantly less severe decreases in brain levels of dopamine, norepinephrine, and serotonin following exposure to chronic EF stress. Increases in serum levels of corticosterone and expression of c-Fos were also less pronounced in mice treated with (-)-sesamin (25 and 50 mg/kg). These results suggest that (-)-sesamin may protect against the effects of chronic EF stress-induced anxiety disorders by modulating dopamine, norepinephrine, and serotonin levels, c-Fos expression, and corticosterone levels.

  16. Individualizing Opioid Use Disorder (OUD Treatment: Time to Fully Embrace a Chronic Disease Model

    Directory of Open Access Journals (Sweden)

    Richard Gustin

    2015-02-01

    Full Text Available The current opioid epidemic in the United States is changing our perceptions of the face of addiction. Opioid Use Disorder (OUD has become pervasive and is affecting all ethnicities, races, socioeconomic classes, the young and the old. In 2015, 46 people will lose their life each day to a chronic brain disease that is going unnoticed and undertreated. Over the last five decades, numerous scientific and clinical breakthroughs have allowed for a better understanding of the mechanisms underlying addiction, and the development of medications that can help support a patient’s long-term recovery. All of those that have contributed to these advancements have aided in redefining addiction as a primary, chronic disease of the brain reward, motivation, memory and related circuitry; however, our treatment strategies have not necessarily advanced to the same extent as our current understanding of the disease. This commentary will explore how personal philosophies can bias treatments strategies and definitions of treatment success, and prevent adoption of chronic disease treatment models that would significantly improve the quality of life of those suffering with OUD. This is a challenge to consider how our views and stigma can impact a patient’s recovery. We are currently losing a battle with a disease that is taking the lives of 46 individuals daily; it is time to fully embrace a chronic disease model which comprises an integrated pharmacopsychosocial approach for treating the biopsychosocial disorder that is addiction to reverse these trends.

    Full Text Available Background and Objectives: Diagnostic reliability is of major concern both to clinicians and researchers. The aim has been to investigate the trustworthiness of clinical ICD-10 affective disorder diagnoses for research purpose. Methods: 150 ECT patients with chronic affective disorders were investigated. A standardized schema for basic anamnesis and the Operational Criteria Checklist for Psychotic and Affective Illness (OPCRIT were used. The sensitivity, specificity, positive and negative predictive values of clinical affective disorder ICD-10 diagnoses and the formal agreement between clinical ICD-10, OPCRIT ICD-10 and DSM-IV diagnoses were determined using unweighted κ-statistics. Results: The sensitivity, specificity, positive and negative predictive values of the clinical bipolar diagnoses was 0.55, 0.75, 0.42 and 0.84, respectively. The sensitivity, specificity, positive and negative predictive values of the clinical unipolar diagnoses was 0.79, 0.55, 0.77 and 0.58, respectively. The agreement between clinical ICD-10 and OPCRIT ICD-10 bipolar vs. non-bipolar diagnoses was low, κ = 0.28. The agreement between clinical ICD-10 and OPCRIT ICD-10 unipolar vs. non-unipolar diagnoses was low, κ = 0.35. The agreement between OPCRIT ICD-10 and DSM-IV diagnoses on bipolar vs. non-bipolar disorders was high, κ = 0.91, and the agreement on unipolar vs. non-unipolar disorders was fairly high, κ = 0.78. Conclusions: This study demonstrates that the reliability of clinical ICD-10 diagnoses of affective disorders from chronic subjects with a history of ECT is problematic despite sample homogeneity on basic clinical, demographic and epidemiological parameters.

    Full Text Available BACKGROUND: This case-control study utilized a population-based dataset to examine the association of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS with prior anxiety disorder (AD by comparing the risk of prior AD between subjects with CP/CPPS and matched controls in Taiwan. METHODS: We study used data sourced from the Taiwan Longitudinal Health Insurance Database. The cases comprised 8,088 subjects with CP/CPPS and 24,264 randomly matched subjects as controls. We used a conditional logistic regression to calculate the odds ratio (OR for having been previously diagnosed with AD between subjects with and without CP/CPPS. RESULTS: Of the 24,264 sampled subjects, 2309 (7.1% had received an AD diagnosis before the index date; AD was found in 930 (11.5% cases and 1379 (5.7% controls (p59 years. In particular, subjects aged 40∼59 years had the highest adjusted OR (of 2.53 for prior AD among cases compared to controls. CONCLUSIONS: We concluded that CP/CPPS is associated with previously diagnosed AD. Urologists should be alert for the association between CP/CPPS and AD in subjects suffering from AD.

    Full Text Available BACKGROUND: Suicide and death by accidents in persons with schizophrenia and bipolar disorder are common, but excess mortality from natural death accounts for even more years of life lost. The impact of somatic comorbidity, however, often is not duly considered in analyses and explanations of excess mortality in patients with psychotic disorders. OBJECTIVE/METHODS: This study investigates and evaluates the impact of 19 severe chronic diseases on excess mortality due to diseases and medical conditions (natural death in individuals with psychotic disorders compared with the general population using a population-based cohort study in Denmark. Incidence/mortality rate ratios of admission/mortality were calculated using survival analysis. RESULTS: Cohort members with psychotic disorders had higher incidence rates of hospital contacts for almost all of the 19 disorders than the general population. The mortality rate ratio (MRR of natural death was 7.10 (95% CI 6.45, 7.81 for schizophrenic men, decreasing to 4.64 (95% CI 4.21, 5.10 after adjustment for the somatic disorders. The same pattern existed in women and in both genders with bipolar disorder. Highest MRRs were observed for psychotic patients without hospital admissions with the investigated somatic disorders. CONCLUSION: Chronic somatic diseases accounted for half of the excess mortality in patients with schizophrenia or bipolar disorder. Chronic disorders investigated in this paper seem to be under-treated or under-detected among such patients.

    The discovery of JAK2/MPL mutations in patients with myeloproliferative neoplasms (MPN) led to clinical development of Janus kinase (JAK) inhibitors for treatment of MPN. These inhibitors improve constitutional symptoms and splenomegaly but do not significantly reduce mutant allele burden in patients. We recently showed that chronic exposure to JAK inhibitors results in inhibitor persistence via JAK2 transactivation and persistent JAK–signal transducer and activator of transcription signaling. We performed genetic and pharmacologic studies to determine whether improved JAK2 inhibition would show increased efficacy in MPN models and primary samples. Jak2 deletion in vivo led to profound reduction in disease burden not seen with JAK inhibitors, and deletion of Jak2 following chronic ruxolitinib therapy markedly reduced mutant allele burden. This demonstrates that JAK2 remains an essential target in MPN cells that survive in the setting of chronic JAK inhibition. Combination therapy with the heat shock protein 90 (HSP90) inhibitor PU-H71 and ruxolitinib reduced total and phospho-JAK2 and achieved more potent inhibition of downstream signaling than ruxolitinib monotherapy. Combination treatment improved blood counts, spleen weights, and reduced bone marrow fibrosis compared with ruxolitinib alone. These data suggest alternate approaches that increase JAK2 targeting, including combination JAK/HSP90 inhibitor therapy, are warranted in the clinical setting. PMID:24470592

    Full Text Available Abstract Background Mood and anxiety symptoms in chronic hepatitis C (CHC may be related to the patient awareness of the diagnosis and prognosis, to side effects induced by interferon (IFN-alpha treatment, as well as to substance abuse. However, the observation of metabolic alterations in patients with CHC has led to hypothesize a direct effect of hepatitis C virus (HCV on brain function. This study was aimed at elucidating whether CHC is associated with specific anxiety or mood disorders independently of confounding factors. Methods Patient cohort: consecutive patients, 135 with CHC and 76 with chronic hepatitis B (CHB. Exclusion criteria: previous treatment with IFN-alpha, co-infection with HCV and hepatitis B virus, infection with human immunodeficiency virus, drug or alcohol abuse, or malignancies. Controls: subjects without evidence of hepatitis randomly extracted from the database of a previous epidemiological study; they were divided into two groups of 540 (332 males and 304 (220 males as controls for patients with CHC and CHB, respectively. The psychiatric diagnosis was formulated by means of the Composite International Diagnostic Interview Simplified carried out by a physician according to DSM-IV criteria. Results A higher lifetime prevalence of major depressive disorder (MDD was observed among CHC compared to CHB or controls. The risk of MDD was not statistically different between CHB and controls. Both the CHC and CHB groups showed a significantly higher frequency of panic disorder when compared to controls. No statistical differences were observed in the prevalence of general anxiety disorder and social phobia when CHC or CHB were compared to controls. Conclusion The present study provides the first evidence of an association between CHC and MDD, diagnosed on the basis of well-defined international criteria. This association is independent of treatment with IFN-alpha and is not influenced by substance or alcohol abuse. By contrast

    Pharmacological and behavioral interventions have focused on reducing tic severity to alleviate tic-related impairment for youth with chronic tic disorders (CTDs), with no existing intervention focused on the adverse psychosocial consequences of tics. This study examined the preliminary efficacy of a modularized cognitive behavioral intervention ("Living with Tics", LWT) in reducing tic-related impairment and improving quality of life relative to a waitlist control of equal duration. Twenty-four youth (ages 7-17 years) with Tourette Disorder or Chronic Motor Tic Disorder and psychosocial impairment participated. A treatment-blind evaluator conducted all pre- and post-treatment clinician-rated measures. Youth were randomly assigned to receive the LWT intervention (n=12) or a 10-week waitlist (n=12). The LWT intervention consisted of up to 10 weekly sessions targeted at reducing tic-related impairment and developing skills to manage psychosocial consequences of tics. Youth in the LWT condition experienced significantly reduced clinician-rated tic-impairment, and improved child-rated quality of life. Ten youth (83%) in the LWT group were classified as treatment responders compared to four youth in the waitlist condition (33%). Treatment gains were maintained at one-month follow-up. Findings provide preliminary data that the LWT intervention reduces tic-related impairment and improves quality of life for youth with CTDs.

    Full Text Available The aim of the study was to examine the quality of life and clinical features of non-psychotic mental disorders in patients with acute and chronic pancreatitis. Polymorphic mental disorders of different clinical content and severity in most cases not only comorbid diseases of the pancreas, but often are the first earliest clinical manifestations of the disease. The data on clinical and psychopathological features of non-psychotic mental disorders in patients with acute and chronic pancreatitis are given. The share of cardinal syndromes such as asthenic-neurotic and anxious-depressive was established and described. The study was conducted using the following methods: clinical psychiatric questionnaire of common type MOS Short Form-36 Health Survey (SF-36 and methods of mathematical processing. The sample included 131 patients with acute and chronic pancreatitis. Clinical variant of acute and chronic pancreatitis debut were the features of mental disorders and psychotic-pathologic structure of non-psychotic mental disorders. Various indicators of quality of life in acute and chronic pancreatitis in presence of psychotic disorders were revealed.

    Dropout from outpatient mental health treatment may contribute to high rates of relapse and rehospitalization among veterans with chronic posttraumatic stress disorder (PTSD). In a quasi-experimental cohort study, 87 male and 17 female veterans discharging from residential PTSD treatment received either standard referral to outpatient care (N = 77) or standard referrals supplemented by biweekly telephone calls (N = 27). Telephone monitoring and support was feasible and acceptable to 85% of clients. Compared to prior patient cohorts, clients receiving telephone support were twice as likely (88% vs. 43%) to complete an outpatient visit within 1 month of discharge and reported higher satisfaction with care.

    Due to relatively recent and ongoing world events (eg, terrorist attacks, wars, and natural disasters), there has been a shift in attention from some of the more common psychiatric illnesses to one of the more elusive, namely, posttraumatic stress disorder (PTSD). PTSD is a severe, and often chronic, condition that can lead to significant morbidity and mortality. Although originally a condition seen primarily among war veterans, PTSD is now becoming more prevalent in the general community. PTSD often presents concurrently with other conditions, such as depression, bipolar, anxiety/panic disorders, and alcohol and drug abuse. Because of this, PTSD often goes unrecognized and is underdiagnosed in clinical practice. Thus, an opportunity for pharmacist intervention exists, both in the institution and in the community. With proper education and training, pharmacists can be efficient in screening for signs and symptoms of PTSD, triaging appropriate patients, and can play an integral role in managing the diverse array of drug therapy options for PTSD.

    Full Text Available Background: Creating autoantibodies against thyroid in hepatitis C patients who are being treated with interferon is now recognized for several years. Recently, some studies have claimed that prevalence of autoimmune thyroid disorders in Hepatitis C patients is higher when they are not treated by interferon and/or at the beginning of diagnosis, however the area still remained controversial. In order to analyze autoimmune thyroid disorders in Hepatitis C patients who are not still treated by interferon and compare them with the control group this study has been conducted.Methods: A Case-Control study including 86 chronic hepatitis C patients before commencing treatment by interferon and 86 healthy volunteer individuals were examined. Data was collected using demographic and clinical variables questionnaires from both groups. FT4, TSH, Anti TPO and Anti TG examinations carried out in both group. Results: The findings of this study showed increase Anti TPO in 4 cases in 13 case, increased is Anti TG in 5 case, sub clinical hypothyroid, ism sub clinical hyperthyroid in 3 ism and hyperthyroid ism in one case in the case group were observed. There was no significant difference between the case and the control group. Conclusion: We can conclude that there is no relationship between chronic hepatitis C infection and autoimmune thyroid.

    Full Text Available For Korean dialysis patients, chronic kidney disease–mineral bone disorder is a serious burden because of cardiovascular calcification and mortality. However, recent epidemiologic data have demonstrated that many patients undergoing maintenance hemodialysis are out of the target ranges of serum calcium, phosphorus, and intact parathyroid hormone. Thus, we felt the necessity for the development of practical recommendations to treat abnormal serum phosphorus, calcium, and iPTH in dialysis patients. In this paper, we briefly comment on the measurement of serum calcium, phosphorus, iPTH, dialysate calcium concentration, dietary phosphorus restriction, use of phosphate binders, and medical and surgical options to correct secondary hyperparathyroidism. In particular, for the optimal management of secondary hyperparathyroidism, we suggest a simplified medication adjustment according to certain ranges of serum phosphorus and calcium. Large-scale, well-designed clinical studies are required to support our strategies to control chronic kidney disease–mineral bone disorder in this country. Based on such data, our practice guidelines could be established and better long-term outcomes should be anticipated in our dialysis patients.

    Quality of life (QOL) is an important clinical endpoint, but it remarkably varies in patients with similar neurological conditions. This study explored the role of spirituality (i.e., the complex of personal transcendence, connectedness, purpose, and values) in determining QOL in chronic neurological disorders.~Seventy-two patients with epilepsy, brain tumours or ischemic or immune-mediate brain damage compiled inventories for QOL (WHOQOL 100), spirituality (Spiritual, Religious and Personal Beliefs, WHOSRPB), depression (Beck Depression Inventory, BDI), anxiety (State-Trait Anxiety Inventory, STAI), and cognitive self-efficacy (Multiple Ability Self-Report Questionnaire, MASQ) and underwent neuropsychological testing. With respect to 45 healthy controls, the patients reported worse QOL, with no difference between the four patient subgroups. Factor analyses of the WHOSRPB, STAI, and BDI scores and of the MASQ and neuropsychological test scores yielded four (Personal Meaning, Inner Energy, Awe and Openness, Mood) and three factors (Control Functions, Cognition, Memory), respectively. Mood, Cognition, Inner Energy, schooling, and subjective health status correlated with the WHOQOL scores, but at regression analysis only Mood and Inner Energy predicted QOL. This suggests that spirituality, as a personal dimension distinct from mood, contributes to determine QOL. A multidimensional assessment of QOL, including personal facets, may explain differences between patients with chronic neurological disorders.

    Posttraumatic stress disorder (PTSD) is common, is often chronic, and has been associated with greater risk of postoperative mortality in veterans. The purpose of this study was to determine if elective outpatient surgery had a persistent effect on the physical or mental health of veterans with chronic PTSD. A longitudinal, quasi-experimental study was conducted that followed up 60 veterans with chronic PTSD over 12 weeks. Self-reported physical and mental health, depressive symptom severity, and posttraumatic symptom severity were measured in 29 veterans undergoing outpatient elective surgery and 31 veterans not having elective surgery (controls). Data collection was performed at baseline and repeated 1, 4, and 12 weeks after surgery or enrollment. At baseline, both surgical and control subjects reported poor physical and mental subjective health status. After surgery, surgical group subjects reported mean age- and gender-adjusted reductions of 3.9 points on the Physical Component Summary score and 2.9 points on the Mental Component Summary score of the Veterans Rand 36-item Health Survey, which resolved by 4 weeks after surgery. These findings suggest that veterans with PTSD were at greater risk of mortality because of poor baseline health, but did not demonstrate persistent decline in health following common elective surgical procedures.

    Full Text Available The primary objective of the present study was to determine how simulated severe cervical pain affects cervical motion in patients suffering from two distinct chronic cervical disorders: whiplash (n=25 and degenerative changes (n=25. The second objective was to derive an index that would allow the differentiation of maximal from submaximal performances of cervical range of motion. Patients first performed maximal movement of the head (maximal effort in each of the six primary directions and then repeated the test as if they were suffering from a much more intense level of pain (submaximal effort. All measurements were repeated within four to seven days. In both groups, there was significant compression of cervical motion during the submaximal effort. This compression was also highly stable on a test-retest basis. In both groups, a significantly higher average coefficient of variation was associated with the imagined pain and it was significantly different between the two clinical groups. In the whiplash group, a logistic regression model allowed the derivation of coefficient of variation-based cutoff scores that might, at selected levels of probability and an individual level, identify chronic whiplash patients who intentionally magnify their motion restriction using pain as a cue. However, the relatively small and very stable compression of cervical motion under pain simulation supports the view that the likelihood that chronic whiplash patients are magnifying their restriction of cervical range of motion using pain as a cue is very low.

    Full Text Available Facial pain often persists long after any identifiable organic pathology has healed. Moreover, in a subgroup of patients with temporomandibular disorder (TMD, no treatment is effective. Knowledge of factors associated with persistent pain in TMD could help identify personalized treatment approaches. Therefore, we conducted a critical review of the literature for the period from January 2000 to December 2013 to identify factors related to TMD development and persistence. The literature findings showed that chronic TMD is marked by psychological distress (somatization and depression, affective distress, fear of pain, fear of movement, and catastrophizing and characteristics of pain amplification (hyperalgesia and allodynia. Furthermore, these factors seem to interact in TMD development. In addition, our review demonstrates that upregulation of the serotonergic pathway, sleep problems, and gene polymorphisms influence the chronicity of TMD. We conclude that psychological distress and pain amplification contribute to chronic TMD development, and that interactions among these factors complicate pain management. These findings emphasize the importance of multidisciplinary assistance in TMD treatment.

    The aim of this study was to investigate whether chronic daily headache (CDH) and temporomandibular disorders (TMD) patients present with different psychological and sleep quality characteristics. Sixty-seven patients diagnosed with CDH, according to classification criteria from Silberstein et al., were matched by age and sex with 67 patients who had a primary diagnosis of myofascial pain (MP) and 67 patients with a primary diagnosis of TMJ intracapsular pain (IC) according to the Research Diagnostic Criteria for TMD. The CDH group was comprised of three mutually exclusive diagnostic groups: chronic migraine (n = 35); chronic tension-type headache (n = 26); 'other CDH' (n = 6). All patients completed a battery of psychological and sleep quality questionnaires. All CDH subgroups showed similar psychological and sleep quality profiles. Pain intensity and duration were controlled in the multivariate analyses (Mancova) by treating them as covariates. The CDH and MP groups revealed higher levels of psychological distress than the IC group on most psychological domains. The MP group also revealed numerically higher levels of psychological distress in most psychological domains than the CDH group, although these differences were generally not significant. We did not find significant differences between the three groups on post traumatic stress symptoms either. Sleep quality was significantly worse in the MP group than in the CDH and IC groups. These results are discussed in the context of multimodal patient evaluation and treatments that are often necessary for successful clinical management.

    Chronic recurrent multifocal osteomyelitis (CRMO) is an autoinflammatory disorder that primarily affects bone but is often accompanied by inflammation of the skin and/or gastrointestinal tract. The etiology is unknown but evidence suggests a genetic component to disease susceptibility. Although most cases of CRMO are sporadic, there is an autosomal recessive syndromic form of the disease, called Majeed syndrome, which is due to homozygous mutations in LPIN2. In addition, there is a phenotypically similar mouse, called cmo (chronic multifocal osteomyelitis) in which the disease is inherited as an autosomal recessive disorder. The cmo locus has been mapped to murine chromosome 18. In this report, we describe phenotypic abnormalities in the cmo mouse that include bone, cartilage and skin inflammation. Utilizing a backcross breeding strategy, we refined the cmo locus to a 1.3 Mb region on murine chromosome 18. Within the refined region was the gene pstpip2, which shares significant sequence homology to the PSTPIP1. Mutations in PSTPIP1 have been shown to cause the autoinflammatory disorder PAPA syndrome (pyogenic arthritis, pyoderma gangrenosum and acne). Mutation analysis, utilizing direct sequencing, revealed a single base pair change c.293T --> C in the pstpip2 gene resulting in a highly conserved leucine at amino acid 98 being replaced by a proline (L98P). No other mutations were found in the coding sequence of the remaining genes in the refined interval, although a 50 kb gap remains unexplored. These data suggest that mutations in pstpip2 may be the genetic explanation for the autoinflammatory phenotype seen in the cmo mouse.

    Full Text Available Aim. To evaluate effects of broncholytic therapy on ventricular rhythm disorders and high resolution electrocardiogram indices in patients with chronic obstructive pulmonary disease (COPD.Material and methods. 144 patients (54 women and 90 men; aged 47,1±1,5 y.o. with COPD and 35 patients of control group without respiratory and cardiovascular diseases (23 men and 12 women; aged 42,4±2,8 y.o. were examined. 24-hour ECG monitoring and high resolution ECG with time and spectral-time mapping of ventricular ECG complex were performed in patients additionally to routine examination.Results. Reduction of ventricular rhythm disorders rate was detected during therapy with extended-release theophylline or salmeterol/fluticasone in patients with moderate and severe COPD. This effect was more significant for salmeterol/fluticasone treatment. Treatment with extended-release theophylline led to increase of a number of ventricular extra systoles in patients with severe COPD. Salmeterol/fluticasone treatment did not influence number of ventricular extrasystoles. Broncholytic therapy had positive influence on processes of ventricular depolarization. It was shown by high resolution ECG indicators improvement and by late ventricular potential rate reduction.Conclusion. Salmeterol/fluticasone combination is more reasonable than extended-release theophylline for broncholytic therapy in patients with severe COPD and ventricular rhythm disorders.

    Youth with chronic tic disorders (CTD) experience social problems that have been associated with functional impairment and a diminished quality of life. Previous examinations have attributed social difficulties to either tic severity or the symptom severity of coexisting conditions, but have not directly explored performance deficits in social functioning. This report examined the presence and characteristics of social deficits in youth with CTD and explored the relationship between social deficits, social problems, and quality of life. Ninety-nine youth (8-17years) and their parents completed a battery of assessments to determine diagnoses, tic severity, severity of coexisting conditions, social responsiveness, and quality of life. Parents reported that youth with CTD had increased social deficits, with 19% reported to have severe social deficits. The magnitude of social deficits was more strongly associated with inattention, hyperactivity, and oppositionality than with tic severity. Social deficits predicted internalizing and social problems, and quality of life above and beyond tic severity. Social deficits partially mediated the relationship between tic severity and social problems, as well as tic severity and quality of life. Findings suggest that youth with CTD have social deficits, which are greater in the presence of attention-deficit hyperactivity disorder and obsessive compulsive disorder. These social deficits play an influential role in social problems and quality of life. Future research is needed to develop interventions to address social performance deficits among youth with CTD.

    This study investigated the clinical correlates and mediators of self-concept in youth with Chronic Tic Disorders (CTD). Ninety-seven youth aged 6-17 (M = 11.1 ± 2.89; 79.4 % male) with CTD were administered the Yale Global Tic Severity Scale, the Piers-Harris Children's Self-Concept Scale-Second Edition, and self-report and clinician-administered measures assessing behavioral and psychological difficulties and comorbid conditions. Youth with CTD had a slightly below average level of self-concept, with 20 % (n = 19) exhibiting low self-concept. Youth with CTD-only had greater self-concept relative to youth with CTD and obsessive-compulsive disorder (OCD) (p = 0.04) or CTD, OCD, and attention deficit hyperactivity disorder (ADHD) combined (p = 0.009). Medium-to-large-sized associations were observed between youth's self-concept and clinical characteristics (e.g., severity of ADHD, OCD and depressive symptoms). Youth's self-concept partially mediated the relationship between tic severity and depressive symptom severity, and the interaction between tic impairment and youth's reliance on avoidant coping strategies moderated youth's self-concept. Implications, limitations, and recommendations for future interventions are discussed.

    We present a family with three affected males in two generations with congenital neurogenic chronic idiopathic intestinal pseudo-obstruction (CIIP), patent ductus arteriosus, and large platelet thrombocytopenia apparently segregating as an X linked recessive disorder. The pattern of segregation of DNA markers within the family is consistent with linkage to the previously described neurogenic CIIP (CIIPX) locus at Xq28. This combination may represent a new contiguous gene disorder and appears to have a good prognosis with supportive therapy.

    Background Metoprolol treatment is well established for chronic heart failure (CHF) patients, but the central nervous system side effects are often a potential drawback. Objective To investigate the impact of metoprolol treatment on change in mental status of CHF patients with clinical psychological disorders (such as depression, anxiety, and burnout syndrome). Methods From February 2013 to April 2016, CHF patients with clinical mental disorders received metoprolol (23.75 or 47.5 mg, qd PO, dose escalated with 23.75 mg each time until target heart rate [HR] <70 bpm was achieved) at the Second Affiliated Hospital of Kunming Medical University. Mental status was assessed by means of the Hospital Anxiety and Depression Scale (HADS) and the Copenhagen Burnout Inventory (CBI) scale. The primary outcome assessed was change in mental status of patients post-metoprolol treatment and the association with reduction in HR achieved by metoprolol. Results A total of 154 patients (median age: 66.39 years; males: n=101) were divided into eight groups on the basis of their mental status. HR decreased significantly from baseline values in all the groups to <70 bpm in the 12th month, P≤0.0001. The HADS depression and CBI scores significantly increased from baseline throughout the study frame (P≤0.0001 for all groups), but a significant decrease in the HADS anxiety score was observed in patients with anxiety (P≤0.0001 for all groups). Regression analysis revealed no significant correlation in any of the groups between the HR reduction and the change in the HADS/CBI scores, except for a change in the CBI scores of CHF patients with depression (P=0.01), which was HR dependent. Conclusion Metoprolol treatment worsens the depressive and high burnout symptoms, but affords anxiolytic benefits independent of HR reduction in CHF patients with clinical mental disorders. Hence, physicians need to be vigilant while prescribing metoprolol in CHF patients who present with mental disorders

    Abstract Chronic kidney disease (CKD) is a highly prevalent condition in the world. Neurological, psychological, and cognitive disorders, related to CKD, could contribute to the morbidity, mortality, and poor quality of life of these patients. The aim of this study was to assess the neurological, psychological, and cognitive imbalance in patients with CKD on conservative and replacement therapy. Seventy-four clinically stable patients affected by CKD on conservative therapy, replacement therapy (hemodialysis (HD), peritoneal dialysis (PD)), or with kidney transplantation (KT) and 25 healthy controls (HC), matched for age and sex were enrolled. Clinical, laboratory, and instrumental examinations, as renal function, inflammation and mineral metabolism indexes, electroencephalogram (EEG), psychological (MMPI-2, Sat P), and cognitive tests (neuropsychological tests, NPZ5) were carried out. The results showed a significant differences in the absolute and relative power of delta band and relative power of theta band of EEG (P = 0.008, P 2D3) (P 2D3, intact parathyroid hormone (iPTH), phosphorus, and cynical and hysterical personality, are correlated with higher relative power of delta (P = 0.016) and theta band (P = 0.016). Moreover, all NPZ5 scores showed a significant difference between the means of nephropathic patients and the means of the HC, and a positive correlation with eGFR, serum nitrogen, CRP, iPTH, and vitamin D. In CKD patients, simple and noninvasive instruments, as EEG, and cognitive-psychological tests, should be performed and careful and constant monitoring of renal risk factors, probably involved in neuropsychological complications (inflammation, disorders of mineral metabolism, electrolyte disorders, etc.), should be carried out. Early identification and adequate therapy of neuropsychological, and cognitive disorders, might enable a better quality of life and a major compliance with a probable reduction in the healthcare costs.

    Managing individuals with chronic disorders of consciousness raises ethical questions about the appropriateness of maintaining life-sustaining treatments and end-of-life decisions for those who are unable to make decisions for themselves. For many years, the positions fostering the "sanctity" of human life (i.e., life is inviolable in any case) have led to maintaining life-sustaining treatments (including artificial nutrition and hydration) in patients with disorders of consciousness, allowing them to live for as long as possible. Seldom have positions that foster "dignity" of human life (i.e., everyone has the right to a worthy death) allowed for the interruption of life-sustaining treatments in some patients with disorders of consciousness. Indeed, most ethical analyses conclude that the decision to interrupt life-sustaining therapies, including artificial nutrition and hydration, should be guided by reliable information about how the patient wants or wanted to be treated and/or whether the patient wants or wanted to live in such a condition. This would be in keeping with the principles of patient-centered medicine, and would conciliate the duty of respecting both the dignity and sanctity of life and the right to a worthy death. This "right to die" has been recognized in some countries, which have legalized euthanasia and/or physician-assisted suicide, but some groups fear that legalizing end-of-life decisions for some patients may result in the inappropriate use of euthanasia, both voluntary and nonvoluntary forms (slippery slope argument) in other patients. This review describes the current opinions and ethical issues concerning end-of-life decisions in patients with disorders of consciousness, with a focus on the impact misdiagnoses of disorders of consciousness may have on end-of-life decisions, the concept of "dignity" and "sanctity" of human life in view of end-of-life decisions, and the risk of the slippery slope argument when dealing with euthanasia and

    We examined the use of benzodiazepines (BZD), hypnotics, and anxiolytics and their associations with chronic pain diseases (CPD) in patients with major depressive disorder (MDD). A retrospective analysis of 153,913 MDD patients (18-64 years) in a large administrative insured claims database during the year 2006 was performed. Results showed that during the study year, 33.1% of the patients had been prescribed BZD; 16.9%, hypnotics; and 6.1%, anxiolytics. The use of BZD and hypnotics increased with age. Patients with CPD were more likely than those without CPD to use BZD (41.2% vs. 27.0%, p hypnotics (21.7% vs. 13.3%, p hypnotics (OR = 1.49), and anxiolytics (OR = 1.51). Further research is needed to examine the long-term benefits and risks of BZD and hypnotics in the treatment of MDD and CPD.

    This study aimed to determine whether psychological factors associated with Post-Traumatic Stress Disorder (PTSD) identified in Western samples generalize to low Social-Economical-Status (SES) populations in an underdeveloped Asian country. The study included 113 survivors of the 2004-tsunami on the south coast of Sri Lanka, recruited from 4 preschools and 10 villages for displaced persons. With logistic regressions the relations between interview-based PTSD diagnosis and psychological factors were assessed, controlling for putative confounders. Fifteen months post-trauma the prevalence of PTSD was 52.2%. Multivariate analyses indicated that negative interpretation of tsunami-memories was significantly (PPTSD. Of the putative confounders, gender and (non-replaced) lost work equipment were related to current PTSD (PPTSD is quite universal, suggesting that interventions focusing on this factor may be important in treatment of tsunami survivors who are suffering from chronic PTSD.

    A quantitative histological analysis of biopsied bone samples is currently regarded as the gold standard for a diagnosing procedure for bone diseases associated with chronic kidney disease-related mineral and bone disorder. Conventionally, "bone cell activities" and "bone mineralization" are applied as two independent assessment axes, and the histology results are classified into five categories according to these axes. Recently, a new bone histology classification system called the Turnover-Mineralization-Volume system, which applied "cancellous bone volume" as another major assessing axis, was advocated; however, both classification systems have many unsolved problems. Clinicians must realize the limitations in evaluating bone metabolism by bone histology. We will need to establish a new classification method for renal bone diseases independent of histological findings.

    Research has shown that motor and vocal tics fluctuate in frequency, intensity, and form in response to environmental and contextual cues. Behavioral models have proposed that some of the variation in tics may reflect context-dependent interactive learning processes such that once tics are performed, they are influenced by environmental contingencies. The current study describes the results of a function-based assessment of tics (FBAT) from a recently completed study comparing Comprehensive Behavioral Intervention for Tics (CBIT) with supportive psychotherapy. The current study describes the frequency with which antecedent and consequence variables were reported to exacerbate tics and the relationships between these functional variables and sample baseline characteristics, comorbidities, and measures of tic severity. Results showed that tic-exacerbating antecedents and consequences were nearly ubiquitous in a sample of children with chronic tic disorder. In addition, functional variables were related to baseline measures of comorbid internalizing symptoms and specific measures of tic severity.

    The term chronic kidney disease-mineral bone disorder has been coined recently to highlight that the disturbed mineral and bone metabolism is a major contributor to vascular calcification and finally cardiovascular disease. This syndrome is characterized by clinical, biochemical and/or histological findings, i.e. i) biochemical alterations in the homeostasis of calcium, phosphate and their key player parathyroid hormone (PTH), Fibroblast growth factor-23 (FGF-23), klotho and vitamin-D, ii) the occurrence of vascular and/or soft tissue calcification, and iii) an abnormal bone structure and/or turnover. Apart from the combined and synergistic action of "traditional" and uremia-related risk factors, promoters and inhibitors of calcification have to be considered as well. This review will focus on the disturbed mineral metabolism as the triggering force behind distortion of vascular integrity and cardiovascular malfunction in CKD patients.

    Trauma-related nightmares in posttraumatic stress disorder (PTSD) rarely respond to pharmacologic treatment. Neurobiologic data suggest that enhanced brain responsiveness to adrenergic stimulation may contribute to the pathophysiology of trauma-related nightmares in PTSD. Nine older men with chronic PTSD secondary to military or Holocaust trauma were prescribed the lipophilic alpha-1 adrenergic antagonist prazosin for treatment-resistant trauma-related nightmares. Prazosin 2 mg to 4 mg 1 hour before bedtime substantially reduced nightmares and moderately or markedly reduced overall PTSD severity in 8 of 9 subjects. Prazosin was well tolerated. These open-label results are consistent with demonstrated therapeutic efficacy of prazosin for PTSD nightmares and sleep disturbance in a recent placebo-controlled trial in Vietnam veterans.

    Following his discovery of chronic traumatic encephalopathy (CTE) in football players in 2002, Dr. Bennet Omalu hypothesized that posttraumatic stress disorder (PTSD) in military veterans may belong to the CTE spectrum of diseases. The CTE surveillance at the Brain Injury Research Institute was therefore expanded to include deceased military veterans diagnosed with PTSD. The authors report the case of a 27-year-old United States Marine Corps (USMC) Iraqi war veteran, an amphibious assault vehicle crewman, who committed suicide by hanging after two deployments to Fallujah and Ramadi. He experienced combat and was exposed to mortar blasts and improvised explosive device blasts less than 50 m away. Following his second deployment he developed a progressive history of cognitive impairment, impaired memory, behavioral and mood disorders, and alcohol abuse. Neuropsychiatric assessment revealed a diagnosis of PTSD with hyperarousal (irritability and insomnia) and numbing. He committed suicide approximately 8 months after his honorable discharge from the USMC. His brain at autopsy appeared grossly unremarkable except for congestive brain swelling. There was no atrophy or remote focal traumatic brain injury such as contusional necrosis or hemorrhage. Histochemical and immunohistochemical brain tissue analysis revealed CTE changes comprising multifocal, neocortical, and subcortical neurofibrillary tangles and neuritic threads (ranging from none, to sparse, to frequent) with the skip phenomenon, accentuated in the depths of sulci and in the frontal cortex. The subcortical white matter showed mild rarefaction, sparse perivascular and neuropil infiltration by histiocytes, and mild fibrillary astrogliosis. Apolipoprotein E genotype was 3/4. The authors report this case as a sentinel case of CTE in an Iraqi war veteran diagnosed with PTSD to possibly stimulate new lines of thought and research in the possible pathoetiology and pathogenesis of PTSD in military veterans as part of

    This pilot study assessed the effects of cardiopulmonary exercise testing and cardiorespiratory fitness on plasma neuropeptide Y (NPY), allopregnanolone and pregnanolone (ALLO), cortisol, and dehydroepiandrosterone (DHEA), and their association with pain sensitivity. Medication-free trauma-exposed participants were either healthy (n = 7) or experiencing comorbid chronic pain/posttraumatic stress disorder (PTSD) (n = 5). Peak oxygen consumption (VO2) during exercise testing was used to characterize cardiorespiratory fitness. Peak VO2 correlated with baseline and peak NPY levels (r = 0.66, p exercise-induced changes in ALLO (r = 0.89, p exercise correlated with pain threshold 30 min after exercise (r = 0.65, p exercise-induced increases in ALLO correlated with pain tolerance 30 min after exercise (r = 0.64, p exercise-induced changes in cortisol and DHEA levels were inversely correlated with pain tolerance after exercise (r = -0.69, p exercise, which in turn relate to pain sensitivity. Future work will examine whether progressive exercise training increases cardiorespiratory fitness in association with increases in NPY and ALLO and reductions in pain sensitivity in chronic pain patients with PTSD.

  17. The immunomodulatory properties of Helicobacter pylori confer protection against allergic and chronic inflammatory disorders

    Full Text Available Chronic infection with the gastric bacterial pathogen Helicobacter pylori causes gastritis and predisposes carriers to a high risk of developing gastric and duodenal ulcers, gastric cancer and gastric lymphoma, but has also recently been shown to protect against certain allergic and chronic inflammatory disorders. The immunomodulatory properties that allow the bacteria to persist for decades in infected individuals in the face of a vigorous, yet ultimately non-protective, innate and adaptive immune response may at the same time confer protection against allergies, asthma and inflammatory bowel diseases. Experimental evidence from mouse models suggests that H. pylori has evolved to skew the adaptive immune response towards immune tolerance rather than immunity, which promotes persistent infection on the one hand, and inhibits auto-aggressive and allergic T-cell responses on the other. Regulatory T-cells mediating peripheral immune tolerance have emerged as key cellular players in facilitating persistent infection as well as protection from allergies, in both observational studies in humans and experimental work in mice. Recent data suggest that H. pylori actively targets dendritic cells to promote tolerance induction. The findings discussed in this review raise the possibility of harnessing the immunomodulatory properties of H. pylori for the prevention and treatment of allergic and auto-immune diseases, and also provide new insights relevant for H. pylori-specific vaccine development.

    Vitamin D has been previously recognized to play important roles in human immune system and function. In the pulmonary system, vitamin D regulates the function of antimicrobial peptides, especially cathelicidin/LL-37. Human cathelicidin/LL-37 is a bactericidal, bacteriostatic, and antiviral endogenous peptide with protective immune functions. Chronic exposure to excessive alcohol has the potential to reduce levels of vitamin D (inactive vitamin D [25(OH)D3] and active vitamin D [1, 25(OH)2D3]) and leads to downregulation of cathelicidin/LL-37. Alcohol-mediated reduction of LL-37 may be partly responsible for increased incidence of more frequent and severe respiratory infections among subjects with alcohol use disorder (AUD). The objective of this study was to investigate the mechanisms by which alcohol exerts its influence on vitamin D metabolism. In addition, the aim was to establish associations between chronic alcohol exposures, levels of pulmonary vitamin D, and cathelicidin/LL-37 using broncho-alveolar lavage fluid samples of subjects with AUD and healthy controls. Findings from the experiment showed that levels of inactive vitamin D (25(OH)D3), active vitamin D (1, 25(OH)2D3), cathelicidin/LL-37, and CYP27B1 proteins were significantly reduced (P < 0.05) when compared with the matched healthy control group. However, CYP2E1 was elevated in all the samples examined. Chronic exposure to alcohol has the potential to reduce the levels of pulmonary vitamin D and results in subsequent downregulation of the antimicrobial peptide, LL-37, in the human pulmonary system.

    Low back pain (LBP) is a very common but largely self-limiting condition. The problem arises however, when LBP disorders do not resolve beyond normal expected tissue healing time and become chronic. Eighty five percent of chronic low back pain (CLBP) disorders have no known diagnosis leading to a classification of 'non-specific CLBP' that leaves a diagnostic and management vacuum. Even when a specific radiological diagnosis is reached the underlying pain mechanism cannot always be assumed. It is now widely accepted that CLBP disorders are multi-factorial in nature. However the presence and dominance of the patho-anatomical, physical, neuro-physiological, psychological and social factors that can influence the disorder is different for each individual. Classification of CLBP pain disorders into sub-groups, based on the mechanism underlying the disorder, is considered critical to ensure appropriate management. It is proposed that three broad sub-groups of CLBP disorders exist. The first group of disorders present where underlying pathological processes drive the pain, and the patients' motor responses in the disorder are adaptive. A second group of disorders present where psychological and/or social factors represent the primary mechanism underlying the disorder that centrally drives pain, and where the patient's coping and motor control strategies are mal-adaptive in nature. Finally it is proposed that there is a large group of CLBP disorders where patients present with either movement impairments (characterized by pain avoidance behaviour) or control impairments (characterized by pain provocation behaviour). These pain disorders are predominantly mechanically induced and patients typically present with mal-adaptive primary physical and secondary cognitive compensations for their disorders that become a mechanism for ongoing pain. These subjects present either with an excess or deficit in spinal stability, which underlies their pain disorder. For this group

    The present review provides an update of the biological profile of Pycnogenol in the light of its use in the treatment of chronic venous insufficiency (CVI) and related venous disorders such as deep vein thrombosis (DVT), post-thrombotic syndrome, long haul air-travel-related leg oedema, venous ulcers and acute haemorrhoids. Pycnogenol is a French maritime pine bark extract produced from the outer bark of Pinus pinaster Ait. subsp. atlantica. Its strong antioxidant, anti-inflammatory and vasodilator activities, antithrombotic effects and collagen stabilizing properties make it uniquely able to target the multi facet pathophysiology of CVI and related venous disorders. Clinical studies have shown that it can reduce oedema of the legs in CVI, reduce the incidence of deep venous thrombosis during long haul flights and enhance the healing of venous ulcers and haemorrhoidal episodes by topical application and/or oral administration. This review highlights clinical research findings on the safety, compliance and efficacy of Pycnogenol, including its use in combination products.

  8. Elevated [11C]-D-deprenyl uptake in chronic Whiplash Associated Disorder suggests persistent musculoskeletal inflammation.

    Clas Linnman

    Full Text Available There are few diagnostic tools for chronic musculoskeletal pain as structural imaging methods seldom reveal pathological alterations. This is especially true for Whiplash Associated Disorder, for which physical signs of persistent injuries to the neck have yet to be established. Here, we sought to visualize inflammatory processes in the neck region by means Positron Emission Tomography using the tracer (11C-D-deprenyl, a potential marker for inflammation. Twenty-two patients with enduring pain after a rear impact car accident (Whiplash Associated Disorder grade II and 14 healthy controls were investigated. Patients displayed significantly elevated tracer uptake in the neck, particularly in regions around the spineous process of the second cervical vertebra. This suggests that whiplash patients have signs of local persistent peripheral tissue inflammation, which may potentially serve as a diagnostic biomarker. The present investigation demonstrates that painful processes in the periphery can be objectively visualized and quantified with PET and that (11C-D-deprenyl is a promising tracer for these purposes.

    JAK2 (V617F) is associated with a genetic predisposition to its acquisition,as it is preferentially found in subjects with a common constitutional JAK2 haplotype known as 46/1 or GGCC. A recent study suggests that a genetic predisposition to acquisition of MPL mutation may exist in sporadic patients, since an association was found with the JAK2 46/1 haplotype. We genotyped 509 patients with myeloproliferative neoplasms (MPN), 7% of which carrying a somatic mutation of MPL Exon 10. We found that the JAK2 GGCC haplotype was closely associated with JAK2 (V617F) (OR 1.84, P < 0.001) but not with MPL mutations (OR 0.98), suggesting a different genetic background for these molecular lesions.

    Full Text Available In 2005, several groups identified a single gain-of-function point mutation in the JAK2 kinase that was present in the majority of patients with myeloproliferative neoplasms (MPNs. Since this discovery, much effort has been dedicated to understanding the molecular consequences of the JAK2V617F mutation in the haematopoietic system. Three waves of mouse models have been produced recently (bone marrow transplantation, transgenic and targeted knock-in, which have facilitated the understanding of the molecular pathogenesis of JAK2V617F-positive MPNs, providing potential platforms for designing and validating novel therapies in humans. This Commentary briefly summarises the first two types of mouse models and then focuses on the more recently generated knock-in models.

    Chronic kidney disease (CKD) is a highly prevalent condition in the world. Neurological, psychological, and cognitive disorders, related to CKD, could contribute to the morbidity, mortality, and poor quality of life of these patients. The aim of this study was to assess the neurological, psychological, and cognitive imbalance in patients with CKD on conservative and replacement therapy.Seventy-four clinically stable patients affected by CKD on conservative therapy, replacement therapy (hemodialysis (HD), peritoneal dialysis (PD)), or with kidney transplantation (KT) and 25 healthy controls (HC), matched for age and sex were enrolled. Clinical, laboratory, and instrumental examinations, as renal function, inflammation and mineral metabolism indexes, electroencephalogram (EEG), psychological (MMPI-2, Sat P), and cognitive tests (neuropsychological tests, NPZ5) were carried out.The results showed a significant differences in the absolute and relative power of delta band and relative power of theta band of EEG (P = 0.008, P therapy, and Grade 2-3 in KT patients. The scales of MMPI-2 hysteria and paranoia, are significantly correlated with creatinine, eGFR, serum nitrogen, CRP, 1,25-(OH)2D3, intact parathyroid hormone (iPTH), phosphorus, and cynical and hysterical personality, are correlated with higher relative power of delta (P = 0.016) and theta band (P = 0.016). Moreover, all NPZ5 scores showed a significant difference between the means of nephropathic patients and the means of the HC, and a positive correlation with eGFR, serum nitrogen, CRP, iPTH, and vitamin D.In CKD patients, simple and noninvasive instruments, as EEG, and cognitive-psychological tests, should be performed and careful and constant monitoring of renal risk factors, probably involved in neuropsychological complications (inflammation, disorders of mineral metabolism, electrolyte disorders, etc.), should be carried out.

    In his psychobiological model of personality, Cloninger developed a novel approach concerning the relationships between psychopathological syndromes and personality. We investigated 207 chronic pain patients (CPPs) and compared them to 105 pain-free control subjects. Participants were assessed using the Temperament and Character Inventory (TCI), the Structured-Clinical-Interview-II, the Beck Depression Inventory and the Spielberger Anxiety Inventory. The CPPs scored higher on the depression and state anxiety scales and 41% fulfilled the criteria of having at least one personality disorder (PD). We used a covariance analysis to control for depression and state anxiety and found that the CPPs scored higher on the Harm Avoidance Temperament Dimension and lower on the Self-Directedness and Cooperativeness Character Dimensions. In CPPs, the symptom counts of all PD subtypes were significantly related to low Self-Directedness and, to a lesser degree, low Cooperativeness. The PD symptoms in Cluster A were related to low Reward Dependence, those in Cluster B were related to high Novelty Seeking and the PD symptoms in Cluster C were related to high Harm Avoidance. In multiple hierarchical regression analyses, controlling for age, gender, depression and state anxiety, TCI scales predicted on average 23% in PD symptom counts. The Self-Directedness and Cooperativeness personality traits appeared to be significant predictors in determining the presence or absence of a PD by correctly classifying 75.8% of CPPs. The TCI provides further insight into the mechanisms underlying the development of chronic pain. This useful diagnostic instrument helps to economically and validly facilitate the identification of core PD features.

    The aim of this study is to analyze a group of patients with chronic lymphoproliferative disorders associated with B, C, D hepatitis viral infection. This group of chronic lymphoproliferative disordered patients with associated hepatitis viral infection has been diagnosed and monitored in the Hematology Department of the University Emergency Hospital of Bucharest, between December 2007 and January 2009. Our study is meant to observe the influence of the viral infection on clinical and biological evolution of the enrolled patients. The diagnosis of the chronic lymphoproliferative disorder was based on the bone marrow / lymph node biopsy and flow–cytometry analysis. The positive diagnosis for hepatitis viral infection was established by ELISA serological tests and viremia was performed by TaqMan method at INBI ‘Matei Bals’ Bucharest. The analyzed group is made up of 41 patients, 25/41 (60,97%) females and 16/41 (39,02%) males, with ages: 20–50 years old – 6/41 (14,63%), 51–70 years old – 23/41 (56,09%) and over 71 years old – 12/41 (29,26%) patients. The histological types of CLD: B–cell non–Hodgkin's lymphoma – in 28/41 (68,29%) patients, T–cell non–Hodgkin's lymphoma – 2/41 (4,87%) patients, Hodgkin's lymphoma – 2/41 (4,87%), chronic lymphocytic leukemia – 7/41 (17,07%), Waldenström disease – 2/41 (4,87%) patients. Regarding the type of CLD, 19/41 (46,34%) of the patients have an aggressive type of CLD and 22/41 (53,65%) a non–aggressive type of CLD. The hepatitis viral infection distribution in our patients: 14/41 (34,14%) have HBV infection, 24/41 (58,53%) have HCV infection, double/triple association of viral infection was found in 3/41 (7,31%) patients. Within HBV infection subgroup 9/14 (64,28%) patients have an aggressive type of CLD and 5/14 (35,71%) patients have a non–aggressive type, whereas within the group with HCV infection we found a different distribution: 9/24 (37,5%) patients with aggressive type and 15/24 (62

    Full Text Available Chronic temporomandibular disorder (TMD is known to have strong correlations with psychological factors and to display gender disparity. However, while chronic TMD is known to affect quality of life, large-scale studies investigating the influence on quality of life by gender are scarce.This cross-sectional study assessed the data of 17,198 participants aged ≥19 years who completed chronic TMD and EuroQol-5 Dimension sections in the 4th Korean National Health and Nutrition Examination Survey (2007-2009. We adjusted for covariates (health behavior, sociodemographic factors in regression analysis for complex sampling design to calculate regression coefficients and 95% CIs for gender difference in the association between chronic TMD and quality of life. We also evaluated which covariates of somatic health, mental health, health behavior, and sociodemographic factors weakened the relationship between TMD and EQ-5D.Prevalence of chronic TMD was 1.6% (men 1.3%, women 1.8%, and chronic TMD persisted to negatively impact quality of life even after adjusting for confounding variables. Low sociodemographic factors and health behavior had a negative effect on quality of life. Somatic health and mental health were most affected by chronic TMD. As for quality of life, women were affected to a greater extent than men by TMD. Women were more affected by osteoarthritis and general mental health (stress, depressive symptoms, and thoughts of suicide, and men by employment.These results imply that chronic diseases and psychological factors are important in chronic TMD, and that there may be physiological and pathological gender differences in TMD.

    There is a close functional relationship between the jaw and neck regions and it has been suggested that trigeminal sensory impairment can follow whiplash injury. Inclusion of manageable routines for valid assessment of the facial sensory capacity is thus needed for comprehensive evaluations of patients exposed to such trauma. The present study investigated facial thermal thresholds in patients with chronic whiplash-associated disorders (WADs) with both a qualitative method and quantitative sensory testing (QST). Ten women with pain and dysfunction following a whiplash injury were compared to 10 healthy age-matched women. Thermal detection thresholds were assessed by qualitative chair-side testing and by QST according to the method-of-limits. Seven test sites in the facial skin (overlying each trigeminal branch bilaterally, and the midpoint of the chin) were examined. The detection warm and cold thresholds were defined as the mean values of 10 individual thresholds. For the WAD patients, the qualitative assessment demonstrated both reduced and increased sensitivity compared to the healthy, whereas QST systematically showed significantly higher detection thresholds (i.e., decreased sensitivity) for both cold and warm stimuli. For the individuals who were assessed as having increased sensitivity in the qualitative assessment, the QST displayed either normal or higher thresholds, i.e., decreased sensitivity. The results suggest that QST is more sensitive for detecting thermal sensory disturbances in the face than a qualitative method. The impaired thermal sensitivity among the patients corroborates the notion of altered thermal detection capacity induced by WAD-related pain.

    This study examined self-inflicted burns in case series of four patients with chronic combat-related post-traumatic stress disorder (PTSD). Those patients were hospitalized in the Burn Unit of the University Hospital of Traumatology in Zagreb because of severe burns and had a premorbid psychiatric history of PTSD. Demographic data and information regarding the circumstances surrounding the incident, burn severity, treatment and outcomes of these patients were collected. The authors have analyzed possible impacts of the sensationalistic way in which media present cases of self-inflicted burning that induce other, new cases of this suicide type, known in the literature as "Werther's syndrome". The importance of multidisciplinary approach in the treatment of burn patients is stressed with emphasis on the important role of liaison psychiatrist in treating these patients. It is necessary to educate media people to avoid sensational reporting on this kind of events. Continuous psychiatric treatment of vulnerable individuals could be useful in prevention of self-inflicted burns.

    Visual fixation (VF) of a target is a possible, although atypical, feature of the Unresponsive Wakefulness Syndrome (UWS). Whether VF may indicate residual awareness in these patients is debatable, since it may simply subtend a series of reflex processes. Objective tools should therefore be used to identify aware VF, which depends on the integrity of visuomotor networks encompassing frontal-parietal-occipital areas. The aim of our study was to detect residual visuomotor network functionality potentially sustaining aware VF. To this end, we evaluated the visuomotor integration (VMI) and visual P300 patterns in a chronic Disorder of Consciousness (DOC) sample and a control group of healthy individuals (HC), using an associative stimulation protocol combining transcranial magnetic stimulation (TMS) with visual stimulation through transorbital alternating current stimulation. The Minimally Conscious State (MCS) patients showed preserved patterns of VMI and P300, whereas nearly all the UWS patients showed no significant VMI. Notably, the electrophysiological findings were correlated with the visual domain of the Coma Recovery Scale-Revised. Nonetheless, two fixating UWS individuals had a VMI similar to MCS patients. Our data suggest that some UWS patients showing VF could be aware, but unable to manifest it clearly, probably because of a severe motor output impairment, which is a condition compatible with the Functional Locked-In Syndrome.

    Behavioral responsiveness and awareness levels correlate with the degree of functional connectivity within cortical-thalamocortical networks, whose breakdown accounts for chronic disorders of consciousness (DOC). Our study was aimed at assessing the role of the primary motor area (M1) and premotor-M1 circuitry dysfunction in motor output deterioration in minimally conscious state (MCS) and unresponsive wakefulness syndrome (UWS) patients. As a control group, we included a healthy subject (HC) sample in the study. We evaluated the effects of different types of transcranial magnetic stimuli over M1 by recording post-stimulus time histogram (PSTH), which includes a series of peaks of unit firing activity that match with D and I-waves, characterizing the descending corticospinal volleys evoked by transcranial magnetic stimuli. As compared to HC, DOC patients showed a dysfunction of intra-M1 and premotor-M1 circuits, which correlated with the Coma Recovery Scale-Revised scorings. Nonetheless, one UWS patient showed a partially preserved premotor-M1 circuitry, paralleled by a severe intra-M1 circuitry dysfunction. Our data suggest that motor unresponsiveness in some DOC patients may be due to a pure motor output failure, as in the functional locked-in syndrome (fLIS), rather than to a premotor-motor connectivity impairment, which instead characterizes MCS and UWS.

    Previous studies of the association between posttraumatic stress disorder (PTSD) and chronic widespread pain (CWP) or fibromyalgia have not examined the role of familial or genetic factors. The goals of this study were to determine if symptoms of PTSD are related to CWP in a genetically informative community-based sample of twin pairs, and if so, to ascertain if the association is due to familial or genetic factors. Data were obtained from the University of Washington Twin Registry, which contains 1042 monozygotic and 828 dizygotic twin pairs. To assess the symptoms of PTSD, we used questions from the Impact of Events Scale (IES). IES scores were partitioned into terciles. CWP was defined as pain located in 3 body regions lasting at least 1 week during the past 3 months. Random-effects regression models, adjusted for demographic features and depression, examined the relationship between IES and CWP. IES scores were strongly associated with CWP (P<0.0001). Compared to those in the lowest IES tercile, twins in the highest tercile were 3.5 times more likely to report CWP. Although IES scores were associated with CWP more strongly among dizygotic than among monozygotic twins, this difference was not significant. Our findings suggest that PTSD symptoms, as measured by IES, are strongly linked to CWP, but this association is not explained by a common familial or genetic vulnerability to both conditions. Future research is needed to understand the temporal association of PTSD and CWP, as well as the physiological underpinnings of this relationship.

    Full Text Available Cerebrovascular diseases (CVD are major causes of disability and death in Russia. Stroke is the third significant cause of higher death rates after cardiovascular disease and cancer. The prevalence of circulatory diseases, such as atherosclerosis and hypertension, is on the rise. Therapy for CVD must be aimed at the underlying disease in which vascular catastrophe (atherosclerosis, hypertension, heart disease, etc. develops, at the regression of neurological and psychopathological syndromes, and at the improvement of cerebral blood flow and metabolic processes. Neuroprotective agents, whose efficacy has been established in uncontrolled and small placebo-controlled trials, are widely used in our country. The prescription of these medications is substantiated by the important role of the pathogenetic mechanisms underlying cerebral ischemia. This paper gives data on the clinical use of L-lysine escinate for ischemic stroke (IS, hypertensive crisis, and chronic cerebral circulatory disorders and discusses the mechanism of this drug's action and the pathogenetic mechanisms of cerebrovascular lesions. A number of investigations have shown it expedient to incorporate L-lysine escinate in the combined neuroprotective therapy of patients with IS, cerebral hypertensive crisis, and hypertensive encephalopathy, which is associated with its antiedematous effect, particularly in preventing vasogenic brain edema, in enhancing the tone of cerebral veins, and in improving venous outflow. It is stated that there is a need for an individualized approach to treating CVD, by taking into consideration the existing risk factors and somatic and neurological diseases.

    Background Overlap of aetiological factors and demographic characteristics with clinical observations of comorbidity has been documented in fibromyalgia syndrome, chronic fatigue syndrome (CFS) and borderline personality disorder (BPD). Aims The purpose of this study was to assess the association of BPD with fibromyalgia syndrome and CFS. The authors reviewed literature on the prevalence of BPD in patients with fibromyalgia or CFS and vice versa. Methods A search of five databases yielded six eligible studies. A hand search and contact with experts yielded two additional studies. We extracted information pertaining to study setting and design, demographic information, diagnostic criteria and prevalence. Results We did not identify any studies that specifically assessed the prevalence of fibromyalgia or CFS in patients with BPD. Three studies assessed the prevalence of BPD in fibromyalgia patients and reported prevalence of 1.0, 5.25 and 16.7%. Five studies assessed BPD in CFS patients and reported prevalence of 3.03, 1.8, 2.0, 6.5 and 17%. Conclusions More research is required to clarify possible associations between BPD, fibromyalgia and CFS. Declaration of interest None. Copyright and usage © The Royal College of Psychiatrists 2016.

    The signs of sympathetic and sensory nerve-related disorders are not widely investigated in chronic nonspecific neck pain (NNP) patients. Thus, we performed skin temperature (Tsk), evaporation and touch threshold (TT) measurements to reveal possible dysfunctions at the fingertips of NNP patients (n=60) compared with healthy controls (n=11). Neck pain intensity was the main modifier of Tsk, and age the main modifier of TT in a multivariate model. On comparisons of the subgroups of NNP patients with unilateral (n=26) and bilateral (n=34) symptoms and controls, TT differed and Tsk tended to differ, the unilateral pain patients being found to demonstrate higher TT values on both sides. Interrelations between the measured parameters were found in the controls, but not in the patients. The NNP patients exhibited signs of functional impairment of innervation reflected in changes in tactile sensitivity and vasoactive sympathetic function. These changes may be based on both central and peripheral mechanisms, which possibly differ in patients with unilateral and bilateral symptoms.

    In order to combat chronic immune disorders (CIDs), it is an absolute necessity to understand the bigger picture, one that goes beyond insights at a one-disease, molecular, cellular, and static level. To unravel this bigger picture we advocate an integral, cross-disciplinary approach capable of embracing the complexity of the field. This paper discusses the current knowledge on common pathways in CIDs including general psychosocial and lifestyle factors associated with immune functioning. We demonstrate the lack of more in-depth psychosocial and lifestyle factors in current research cohorts and most importantly the need for an all-encompassing analysis of these factors. The second part of the paper discusses the challenges of understanding immune system dynamics and effectively integrating all key perspectives on immune functioning, including the patient’s perspective itself. This paper suggests the use of techniques from complex systems science in describing and simulating healthy or deviating behavior of the immune system in its biopsychosocial surroundings. The patient’s perspective data are suggested to be generated by using specific narrative techniques. We conclude that to gain more insight into the behavior of the whole system and to acquire new ways of combatting CIDs, we need to construct and apply new techniques in the field of computational and complexity science, to an even wider variety of dynamic data than used in today’s systems medicine.

    The fifth edition of the Diagnostic and Statistic Manual (DSM-5) reclassified some mental disorders recently. Post-traumatic stress disorder (PTSD) is in a new section termed "trauma- and stressor-related disorder". Community-based studies have shown that PTSD is associated with a notably high suicidal risk. In addition to previous findings of comorbidity between chronic daily headache (CDH) and both depressive disorders and anxiety disorders, recent data suggest that frequency of childhood maltreatment, PTSD, and suicidality are also increased in CDH. CDH patients with migraine aura are especially at risk of suicidal ideation. Research suggests that migraine attack, aura, frequency, and chronicity may all be related to serotonergic dysfunction. Vulnerability to PTSD and suicidality are also linked to brain serotonin function, including polymorphisms in the serotonin transporter gene (5-HTTLPR). In the present review, we focus on recent advances in knowledge of traumatic experiences in childhood, PTSD, and suicidality in relation to migraine and CDH. We hypothesize that vulnerability to PTSD is associated with migraine attack, migraine aura, and CDH. We further postulate that these associations may explain some of the elevated suicidal risks among patients with migraine, migraine aura, and/or CDH. Field studies are required to support these hypotheses.

    Attention deficit/hyperactivity disorder (ADHD) is encountered among patients with epilepsy at a significantly higher rate than in the general population. Mechanisms of epilepsy-ADHD comorbidity remain largely unknown. We investigated whether a model of chronic epilepsy in rats produces signs of ADHD, and thus, whether it can be used for studying mechanisms of this comorbidity. Epilepsy was induced in male Wistar rats via pilocarpine status epilepticus. Half of the animals exhibited chronic ADHD-like abnormalities, particularly increased impulsivity and diminished attention in the lateralized reaction-time task. These impairments correlated with the suppressed noradrenergic transmission in locus coeruleus outputs. The other half of animals exhibited depressive behavior in the forced swimming test congruently with the diminished serotonergic transmission in raphe nucleus outputs. Attention deficit/hyperactivity disorder and depressive behavior appeared mutually exclusive. Therefore, the pilocarpine model of epilepsy affords a system for reproducing and studying mechanisms of comorbidity between epilepsy and both ADHD and/or depression.

    Objective To develop and test the psychometric properties of a measure of participation and social inclusion for individuals with a chronic mental disorder - the F-INK. Methods Within a cross-sectional design, mental health patients from different institutional settings (n = 106) and adults from the general population (n = 19) completed the questionnaire in an individual interview with a researcher. To estimate the reliability of two sum-scores on social inclusion and participation, Cronbach's α was computed. To appraise the validity, mean scale scores were compared across different study groups. Results For both scales, reliability was qualified as substantial (α > 0.70). Study groups showed expected differences in mean scores. Conclusion Preliminary findings suggest that the F-INK may be a useful tool for the assessment of social inclusion and social participation in individuals with a chronic mental disorder. However, further testing of the psychometric properties on a larger population is needed.

    Hypertensive disorders of pregnancy (HDP) is one of the most important lethal complications in pregnant mothers. It is also associated with the subsequent development of chronic hypertension. The objective of this study was to identify the clinical risk factors of postpartum chronic hypertension in women diagnosed with HDP.Six hundred patients as HDP, who diagnosed and followed-up at least 6 month after delivery, were included in the study. We divided the included subjects in 2 groups based on the development of postpartum chronic hypertension: presenting with the chronic hypertension, "case group" (n = 41) and without chronic hypertension, "control group" (n = 559).Clinical and demographic factors were evaluated. By multiple regression analysis, early onset hypertension with end-organ dysfunction, smoking, higher prepregnancy body mass index (BMI), and comorbidities, systemic lupus erythematosus (SLE) or antiphospholipid syndrome (APLS), were associated with progression to chronic hypertension in the postpartum period. The value of area under the curves (AUC) for the 5 models, that generated to combine the significant factors, increased from 0.645 to 0.831, which indicated improved prediction of progression to the chronic hypertension. Additional multivariate analysis revealed significant specific risk factors.This retrospective single hospital-based study demonstrated that the clinical risk factors, that is early onset hypertension with end-organ dysfunction, smoking, and higher prepregnancy BMI, were significant independent predictors of chronic hypertension in women after delivery. Identification of risk factors allowed us to narrow the subject field for monitoring and managing high blood pressure in the postpartum period.

    Objectives The usefulness of cases diagnosed in administrative registers for research purposes is dependent on diagnostic validity. This study aimed to investigate the validity and inter-rater reliability of recorded diagnoses of tic disorders and obsessive-compulsive disorder (OCD) in the Swedish National Patient Register (NPR). Design Chart review of randomly selected register cases and controls. Method 100 tic disorder cases and 100 OCD cases were randomly selected from the NPR based on codes from the International Classification of Diseases (ICD) 8th, 9th and 10th editions, together with 50 epilepsy and 50 depression control cases. The obtained psychiatric records were blindly assessed by 2 senior psychiatrists according to the criteria of the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) and ICD-10. Primary outcome measurement Positive predictive value (PPV; cases diagnosed correctly divided by the sum of true positives and false positives). Results Between 1969 and 2009, the NPR included 7286 tic disorder and 24 757 OCD cases. The vast majority (91.3% of tic cases and 80.1% of OCD cases) are coded with the most recent ICD version (ICD-10). For tic disorders, the PPV was high across all ICD versions (PPV=89% in ICD-8, 86% in ICD-9 and 97% in ICD-10). For OCD, only ICD-10 codes had high validity (PPV=91–96%). None of the epilepsy or depression control cases were wrongly diagnosed as having tic disorders or OCD, respectively. Inter-rater reliability was outstanding for both tic disorders (κ=1) and OCD (κ=0.98). Conclusions The validity and reliability of ICD codes for tic disorders and OCD in the Swedish NPR is generally high. We propose simple algorithms to further increase the confidence in the validity of these codes for epidemiological research. PMID:26100027

    The discovery of the JAK2V617F mutation triggered an unexpected flowering of basic and clinical studies in the field of myeloproliferative neoplasms (MPNs), resulting after just a few years in an exceptional amount of new information. One important consequence of those new findings was the modification of the World Health Organization classification and diagnostic algorithms for these diseases, which is still based on the original concept developed by William Dameshek in 1951 and keeps distinct entities under the umbrella of classical Philadelphia-negative MPNs. These MPNs are essential thrombocythemia, polycythemia vera, and primary myelofibrosis. Could a new molecular classification be a better tool to manage MPN patients? Several studies have shown that essential thrombocythemia and primary myelofibrosis can be divided into distinct subtypes based on the presence of the JAK2V617F mutation. Can we now define JAK2-positive diseases to depict a distinct entity from JAK2-negative MPNs? This chapter reviews the significance of JAK2 mutation positivity in the diagnosis, prognosis, and therapy of MPNs.

    Full Text Available Multiple myeloma (MM is a neoplastic lymphoproliferative disorder characterized by uncontrolled monoclonal plasma cell proliferation. Among different isotypes of MM, immunoglobulin D (IgD MM is very rare, representing only 1 to 2% of all isotypes. Chronic myelogenous leukemia (CML is a neoplastic myeloproliferative disorder of pluripotent hematopoietic stem cell, which is characterized by the uncontrolled proliferation of myeloid cells. An 88-year-old male was diagnosed simultaneously with IgD kappa MM and CML. A distinctive feature in this patient was the progression to plasma cell leukemia without any symptomatic myeloma stage. He was treated simultaneously with lenalidomide, bortezomib and imatinib. Synchronous occurrence of these rare hematological malignancies in a single patient is an exceedingly rare event. Multiple hypotheses to explain co-occurrence of CML and MM have been proposed; however, the exact etiological molecular pathophysiology remains elusive.

    Obsessive-compulsive disorder (OCD) is difficult to treat, and more so when comorbid with major depressive disorder (MDD). The aim of the present case study was to examine effects of behavioral activation (BA) and pharmacotherapy with an adult with chronic comorbid OCD and MDD. BA aimed at increasing approach behaviors in life activities and decreasing avoidant and inactive behaviors. After 21 months of treatment at a community mental health clinic, OCD and MDD symptoms, including compulsive checking behaviors, were no longer at clinical levels. Symptom alleviation and psychological health improved in line with increases in activities of living such as self-care, domestic, social, and studying, and decreases in medications from a regimen of mood stabilizers and anxiolytics to a sole antidepressant. The participant was satisfied with treatment procedures and outcome. The results add to growing evidence of effective BA treatments for comorbid disorders that include depression.

    The causes of excess cardiovascular mortality associated with chronic kidney disease (CKD) have been attributed in part to the CKD-mineral bone disorder syndrome (CKD-MBD), wherein, novel cardiovascular risk factors have been identified. New advances in the causes of the CKD-MBD are discussed in this review. They demonstrate that repair and disease processes in the kidneys release factors to the circulation that cause the systemic complications of CKD. The discovery of WNT inhibitors, especially Dickkopf 1 (Dkk1), produced during renal repair as participating in the pathogenesis of the vascular and skeletal components of the CKD-MBD implied that additional pathogenic factors are critical. This lead to the discovery that activin A is a second renal repair factor circulating in increased levels during CKD. Activin A derives from peritubular myofibroblasts of diseased kidneys, wherein it stimulates fibrosis, and decreases tubular klotho expression. Activin A binds to the type 2 activin A receptor, ActRIIA, which is variably affected by CKD in the vasculature. In diabetic/atherosclerotic aortas, specifically in vascular smooth muscle cells (VSMC), ActRIIA signaling is inhibited and contributes to CKD induced VSMC dedifferentiation, osteogenic transition and neointimal atherosclerotic calcification. In nondiabetic/nonatherosclerotic aortas, CKD increases VSMC ActRIIA signaling, and vascular fibroblast signaling causing the latter to undergo osteogenic transition and stimulate vascular calcification. In both vascular situations, a ligand trap for ActRIIA prevented vascular calcification. In the skeleton, activin A is responsible for CKD stimulation of osteoclastogenesis and bone remodeling increasing bone turnover. These studies demonstrate that circulating renal repair and injury factors are causal of the CKD-MBD and CKD associated cardiovascular disease.

    Several studies have reported an increased incidence of coexistent cancer in patients with myeloproliferative neoplasms (MPN), and myelosuppressive treatment has been speculated to be one of the causes. In this study, we have concentrated on malignancies diagnosed before the MPN diagnosis to eliminate the possible influence of MPN treatment. The patients were recruited from the Swedish and Norwegian cancer registries. One thousand seven hundred and 45 patients from the Swedish MPN Quality Registry and 468 patients from the Norwegian National Cancer Registry were included in this study covering a 3-yr period. The results show that primary concurrent cancer is higher among patients with MPN compared to the general population. When pooled together, the Swedish and the Norwegian cohort showed increased prevalence of all types of cancer in general compared with the general population, standard prevalence ratio (SPR) of 1.20 (95% CI 1.07-1.34). Significantly high SPRs were reached for skin malignant melanoma [1.89 (95% CI 1.33-2.62)], prostate cancer [1.39 (95% CI 1.11-1.71)], and hematologic cancer [1.49 (95% CI 1.00-2.12)]. In the polycythemia vera group, the risk of having prior malignant melanoma of the skin was significant, with an SPR of 2.20 (95% CI 1.17-3.77). For patients with essential thrombocythemia and primary myelofibrosis, no significant risks were found. Coexisting cancers have a high impact on the treatment strategies of MPN, as it narrows down the treatment options. Chronic inflammation, as a common denominator of MPN with other cancers, can catalyze each other's existence and progression.

    Full Text Available Javier Pinilla-Ibarz, Kendra L Sweet, Gabriela M Corrales-Yepez, Rami S Komrokji Department of Malignant Hematology, H Lee Moffitt Cancer Center and Research Institute, Tampa, FL, USA Abstract: An important pathogenetic distinction in the classification of myeloproliferative neoplasms (MPNs is the presence or absence of the BCR–ABL fusion gene, which encodes a unique oncogenic tyrosine kinase. The BCR–ABL fusion, caused by the formation of the Philadelphia chromosome (Ph through translocation, constitutes the disease-initiating event in chronic myeloid leukemia. The development of successive BCR–ABL-targeted tyrosine-kinase inhibitors has led to greatly improved outcomes in patients with chronic myeloid leukemia, including high rates of complete hematologic, cytogenetic, and molecular responses. Such levels of treatment success have long been elusive for patients with Ph-negative MPNs, because of the difficulties in identifying specific driver proteins suitable as drug targets. However, in recent years an improved understanding of the complex pathobiology of classic Ph-negative MPNs, characterized by variable, overlapping multimutation profiles, has prompted the development of better and more broadly targeted (to pathway rather than protein treatment options, particularly JAK inhibitors. In classic Ph-negative MPNs, overactivation of JAK-dependent signaling pathways is a central pathogenic mechanism, and mutually exclusive mutations in JAK2, MPL, and CALR linked to aberrant JAK activation are now recognized as key drivers of disease progression in myelofibrosis (MF. In clinical trials, the JAK1/JAK2 inhibitor ruxolitinib – the first therapy approved for MF worldwide – improved disease-related splenomegaly and symptoms independent of JAK2V617F mutational status, and prolonged survival compared with placebo or standard therapy in patients with advanced MF. In separate trials, ruxolitinib also provided comprehensive hematologic control in

    Abstract The purpose of this study was to clarify psychosocial factors/problems, social participation, quality of life (QOL), and rehabilitation needs in chronic-phase traumatic brain injury (TBI) patients with cognitive disorder discharged from the level-1 trauma center (L1-TC), and to inspect the effects of rehabilitation intervention to these subjects. A mixed-method research (cross-sectional and qualitative study) was conducted at an outpatient rehabilitation department. Inclusion criteria of subjects were transfer to the L1-TC due to TBI; acute-stage rehabilitation treatment received in the L1-TC from November 2006 to October 2011; age of ≥18 and social participation, QOL, psychosocial factors/problems, rehabilitation needs, and chronic-phase rehabilitation outcomes were evaluated using the Wechsler Adult Intelligence Scale, Third Edition, the Wechsler Memory Scale-Revised, the Zung Self-Rating Depression Scale, the Sydney Psychosocial Reintegration Scale, Version 2, and the Short Form 36, Version 2, qualitative analysis of semistructured interviews, etc. Participants were classified into achieved-social-participation (n = 11; employed: 8), difficult-social-participation (n = 12; unemployed: 8), and no-cognitive-dysfunction groups (n = 8; no social participation restriction). Relative to the achieved-social-participation group, the difficult-social-participation group showed greater injury and cognitive dysfunction and lower Sydney Psychosocial Reintegration Scale and Short Form 36 role/social component summary scores (64.9/49.1 vs 44.3/30.4, respectively, P social participation status was greatly affected by the later cognitive disorders and psychosocial factors/problems not by the severity of TBI. No changes were observed in these scores following chronic-phase rehabilitation intervention. Chronic-phase TBI with cognitive disorder led to rehabilitation needs, and improvement of subjects’ psychosocial problems and QOL was difficult. PMID

    2006-09-01

    In early 2005, several groups of investigators studying myeloid malignancies described a novel somatic point mutation (V617F) in the conserved autoinhibitory pseudokinase domain of the Janus kinase 2 (JAK2) protein, which plays an important role in normal hematopoietic growth factor signaling. The V617F mutation is present in blood and marrow from a large proportion of patients with classic BCR/ABL-negative chronic myeloproliferative disorders and of a few patients with other clonal hematological diseases such as myelodysplastic syndrome, atypical myeloproliferative disorders, and acute myeloid leukemia. The JAK2 V617F mutation causes constitutive activation of the kinase, with deregulated intracellular signaling that mimics continuous hematopoietic growth factor stimulation. Within 7 months of the first electronic publication describing this new mutation, clinical molecular diagnostic laboratories in the United States and Europe began offering JAK2 mutation testing on a fee-for-service basis. Here, I review the various techniques used by research groups and clinical laboratories to detect the genetic mutation underlying JAK2 V617F, including fluorescent dye chemistry sequencing, allele-specific polymerase chain reaction (PCR), real-time PCR, DNA-melting curve analysis, pyrosequencing, and others. I also discuss diagnostic sensitivity, performance, and other practical concerns relevant to the clinical laboratorian in addition to the potential diagnostic utility of JAK2 mutation tests.

    Full Text Available Background: Acute exacerbations of chronic obstructive pulmonary disorder (AECOPD are known to be associated with increased morbidity and mortality and have a significant socioeconomic impact. The factors that determine frequent hospital readmissions for AECOPD are poorly understood. The present study was done to ascertain failures rates following AECOPD and to evaluate factors associated with frequent readmissions. Materials and Methods: We conducted a prospective study among 186 patients with COPD with one or more admissions for acute exacerbations in a tertiary care hospital. Frequency of previous re-admissions for AECOPD in the past year, and clinical characteristics, including spirometry were ascertained in the stable state both before discharge and at 6-month post-discharge. Failure rates following treatment were ascertained during the follow-up period. All the patients were followed up for a period of 2 years after discharge to evaluate re-admissions for the AECOPD. Results: Of 186 COPD patients admitted for AECOPD, 54% had one or more readmission, and another 45% had two or more readmissions over a period of 2 years. There was a high prevalence of current or ex-heavy smokers, associated co-morbidity, underweight patients, low vaccination prevalence and use of domiciliary oxygen therapy among COPD patients. A total of 12% mortality was observed in the present study. Immediate failure rates after first exacerbation was observed to be 34.8%. Multivariate analysis showed that duration >20 years (OR = 0.37; 95% CI: 0.10-0.86, use of Tiotropium (OR = 2.29; 95% CI: 1.12-4.69 and use of co-amoxiclav during first admission (OR = 2.41; 95% CI: 1.21-4.79 were significantly associated with higher immediate failure rates. The multivariate analysis for repeated admissions revealed that disease duration >10 years (OR = 0.50; 95% CI: 0.27-0.93, low usage of inhaled ICS + LABA (OR = 2.21; 95% CI: 1.08-4.54, and MRC dyspnea grade >3 (OR = 2.51; 95% CI: 1

  13. Is chronic kidney disease-mineral bone disorder (CKD-MBD) really a syndrome?

    The concept of chronic kidney disease-mineral bone disorder (CKD-MBD) does not appear to fulfil the requirements for a syndrome at first glance, but its definition has brought some clear-cut benefits for clinicians and patients, including wider and more complex diagnostic and therapeutic approaches to the management of this challenging set of issues. Admittedly, not all components of CKD-MBD are present in all patients at all times, but these are highly interrelated, involving mineral and bone laboratory abnormalities, clinical and histological bone disease and finally, cardiovascular disease. The presence of typical biological bone ossification processes in an ectopic anatomical location in CKD has helped to define the existence of an unprecedented bone-vascular relationship, extending its interest even to other medical specialities. For now, we believe that CKD-MBD does not reach full criteria to be defined as a syndrome. However, this novel concept has clearly influenced current clinical guidelines. The National Kidney Foundation Kidney Disease Outcomes Quality Initiative (NKF/KDOQI™) guidelines in 2003 for instance recommended that calcium-based phosphate binders should be avoided to treat hyperphosphataemia in the presence of cardiovascular calcifications. In 2009, the KDIGO and other guidelines reinforced and extended this recommendation by stating that it is reasonable to choose oral phosphate binder therapy by taking into consideration other components of CKD-MBD. Similarly, it is also considered reasonable to use information on vascular/valvular calcification to guide the management of CKD-MBD. Our current assumption as a working group 'CKD-MBD' is that CKD-MBD has the potential to be defined a true syndrome, such as a constellation of concurrent signs and symptoms that suggest a common underlying mechanism for these components as opposed to the term disease. The term 'syndrome' also implies that in any patient at risk due to the presence of one or a few

    Chronic myeloid leukemia (CML) is a hematopoietic stem cell disorder included in the broader diagnostic category of myeloproliferative neoplasms, associated with fusion by BCR gene at chromosome 22q11 to ABL1 gene at chromosome 9q34 with the formation of the Philadelphia (Ph) chromosome. In 2–10% of CML cases, the fusion gene arises in connection with a variant translocation, involving chromosomes 9, 22, and one or more different chromosomes; consequently, the Ph chromosome could be masked within a complex chromosome rearrangement. In cases with variant Ph translocation a deletion on der(9) may be more frequently observed than in cases with the classical one. Herein we describe a novel case of CML with complex variant Ph translocation involving chromosomes 9, 12, and 22. We present the hematologic response and cytogenetic response after Imatinib treatment. We also speculated the mechanism which had originated the chromosome rearrangement. PMID:25045550

    This study examines the prevalence and coprevalence with which returning Operation Iraqi Freedom (OIF)/Operation Enduring Freedom (OEF) veterans were reporting symptoms consistent with chronic pain, posttraumatic stress disorder (PTSD), and persistent postconcussive symptoms (PPCS). The medical records of 340 OIF/OEF veterans seen at a Department of Veterans Affairs Polytrauma Network Site were comprehensively reviewed. Analyses indicated a high prevalence of all three conditions in this population, with chronic pain, PTSD, and PPCS present in 81.5%, 68.2%, and 66.8%, respectively. Only 12 of the veterans (3.5%) had no chronic pain, PTSD, or PPCS. The frequency at which these three conditions were present in isolation (10.3%, 2.9%, and 5.3%, respectively) was significantly lower than the frequency at which they were present in combination with one another, with 42.1% of the sample being diagnosed with all three conditions simultaneously. The most common chronic pain locations were the back (58%) and head (55%). These results underscore the complexity of the presenting complaints in OIF/OEF veterans and support the importance of a multidisciplinary team approach to assessment and treatment.

    To improve our knowledge of the causal mechanisms of stress-related disorders such as depression, we need animal models that mirror the situation in patients. One promising model is the chronic psychosocial stress paradigm in male tree shrews, which is based on the territorial behaviour of these animals that can be used to establish naturally occurring challenging situations under experimental control in the laboratory. Co-existence of two males in visual and olfactory contact leads to a stable dominant-subordinate relationship, with subordinates showing distinct stress-induced behavioural and neuroendocrine alterations that are comparable to the symptoms observed during episodes of depression in patients such as constantly elevated circulating glucocorticoid hormones due to a chronic hyperactivity of the hypothalamic-pituitary-adrenal axis. To elucidate whether the chronic psychosocial stress model in tree shrews besides its "face validity" for depression also has "predictive validity", we treated subordinate tree shrews with the tricyclic antidepressant clomipramine and found a time-dependent restoration of both endocrine and behavioural parameters. In contrast, the anxiolytic diazepam was ineffective. Although the chronic psychosocial stress model in tree shrews requires further validation, it has sufficient face, predictive, and construct validity to become an interesting non-rodent model for research on the etiology and pathophysiology of depression.

    Full Text Available  Aims: Investigate subjective health complaints (SHC in chronic whiplash associated disorder (WAD, grade I & II patients, and to identify physical, psychological, and collision associated factors that might be associated with high levels of comorbidity. Method: During the years 2000-2002 171 chronic WAD patients filled in questionnaires and underwent physical examination. The prevalence of SHC was recorded and compared with a representative sample of the Norwegian population (n=1014. Results: The chronic WAD patients reported higher number of subjective health complaints (median: 9 than the general population (median: 5. They showed significantly higher risk of reporting all musculoskeletal complaints, palpitation, heat flushes, sleep problems, tiredness, dizziness, anxiety, depression, breathing difficulties, chest pain, coughing, heartburn, gas discomfort, and obstipation. The patients with the highest level of comorbid subjective health complaints also reported more function loss, reading difficulties, poorer quality of life, higher psychological distress, higher use of medication, and less optimism about their situation. There were no differences however, in any collision factors or physical meassures recorded by physiotherapists between the high, medium and low comorbidity groups. Conclusion: The high comorbidity of other complaints, the strong relationships between degree of comorbidity and psychological factors, and the lack of relationships between degree of comorbidity and collision factors and physical tests, suggest that chronic WAD is best understood as a syndrome and not simply as a neck injury. Sensitization is suggested as a possible psychobiological mechanism

    Full Text Available Mechanisms responsible for derangements in iron homeostasis in chronic inflammatory conditions are not entirely clear. The aim of this study was to test the hypothesis that inflammation affects expression of iron-related proteins in the duodenum and monocytes in patients with chronic inflammatory disorders, thus contributing to dysregulated iron homeostasis. Duodenal mucosal samples and peripheral blood monocytes obtained from patients with chronic inflammatory disorders, viz. ulcerative colitis (UC, Crohn’s disease (CD and rheumatoid arthritis (RA, were used for gene and protein expression studies. Haemoglobin levels were significantly lower and serum C-reactive protein (CRP levels significantly higher in those in the disease groups. Gene expression of several iron-related proteins in the duodenum was significantly up-regulated in patients with UC and CD. In those with UC, it was found that protein expression of divalent metal transporter (DMT1 and ferroportin, which are involved in absorption of dietary non-heme iron, was also significantly higher in the duodenal mucosa. Gene expression of the duodenal proteins of interest correlated positively with one another and negatively with haemoglobin. Gene expression of iron-related proteins in monocytes was studied in patients with UC and found to be unaffected. In a separate group of patients with UC, serum hepcidin levels were found to be significantly lower than in control subjects. In conclusion, expression of iron related proteins was up-regulated in the duodenum of patients with chronic inflammatory conditions in this study. The effects appeared to be secondary to anemia and the consequent erythropoietic drive.

    Jorge Lopes Cavalcante-Neto

    Full Text Available ABSTRACT: CONTEXT AND OBJECTIVE: The disability associated with maternal common mental disorders (CMDs is among the possible explanations for the association between chronic childhood malnutrition and CMDs. CMDs may impair the mother's ability to perform her role, particularly in deprived environments. The present study aimed to evaluate whether disability relating to CMDs could be part of the pathway of the association between childhood malnutrition and maternal CMDs. DESIGN AND SETTING: Cross-sectional study conducted in two institutions: one for malnourished children and another for eutrophic children living in a low-income community in the state of Alagoas, Brazil. METHOD: The cases consisted of 55 malnourished children aged from 12 to 60 months who were attending a nutritional rehabilitation center, with height-for-age z-scores < 2. The controls were 70 eutrophic children of the same age who were attending a day care center in the same area as the cases. The Self-Report Questionnaire made it possible to identify likely cases of maternal CMD. The Sheehan Disability Scale enabled evaluation of the associated disability. RESULTS: Chronic childhood malnutrition was significantly associated with maternal disability relating to CMDs (OR = 2.28; 95% CI: 1.02-5.1. The best logistic regression model using chronic childhood malnutrition as the dependent variable included the following independent variables: higher number of people living in the household; absence of the biological father from the household; and maternal disability relating to CMDs. CONCLUSIONS: If confirmed, the association between chronic childhood malnutrition and maternal disability relating to CMDs may be useful in helping to identify the causal chain between childhood malnutrition and maternal CMDs and to indicate environmental risk factors associated with chronic childhood malnutrition.

    Full Text Available Abstract Background Chronic myelomonocytic leukemia (CMML is a hematological disease close to, but separate from both myeloproliferative disorders (MPD and myelodysplastic syndromes and may show either myeloproliferative (MP-CMML or myelodysplastic (MD-CMML features. Not much is known about the molecular biology of this disease. Methods We studied a series of 30 CMML samples (13 MP- and 11 MD-CMMLs, and 6 acutely transformed cases from 29 patients by using Agilent high density array-comparative genomic hybridization (aCGH and sequencing of 12 candidate genes. Results Two-thirds of samples did not show any obvious alteration of aCGH profiles. In one-third we observed chromosome abnormalities (e.g. trisomy 8, del20q and gain or loss of genes (e.g. NF1, RB1 and CDK6. RAS mutations were detected in 4 cases (including an uncommon codon 146 mutation in KRAS and PTPN11 mutations in 3 cases. We detected 11 RUNX1 alterations (9 mutations and 2 rearrangements. The rearrangements were a new, cryptic inversion of chromosomal region 21q21-22 leading to break and fusion of RUNX1 to USP16. RAS and RUNX1 alterations were not mutually exclusive. RAS pathway mutations occurred in MP-CMMLs (~46% but not in MD-CMMLs. RUNX1 alterations (mutations and cryptic rearrangement occurred in both MP and MD classes (~38%. Conclusion We detected RAS pathway mutations and RUNX1 alterations. The latter included a new cryptic USP16-RUNX1 fusion. In some samples, two alterations coexisted already at this early chronic stage.

    Early differential diagnosis between Tourette's syndrome and chronic tic disorder is difficult but important because both the outcome and the treatment of these two childhood-onset diseases are distinct. We assessed the sensitivity and specificity of brain single-photon emission tomography (SPET) perfusion imaging in distinguishing the two diseases, and characterized their different cerebral perfusion patterns. Twenty-seven children with Tourette's syndrome and 11 with chronic tic disorder (mean age 9.5 and 8.6 years, respectively) underwent brain SPET with technetium-99m hexamethylpropylene amine oxime (HMPAO). Visual interpretation and semi-quantitative analysis of SPET images were performed. On visual interpretation, 22 of 27 (82%) of the Tourette's syndrome group had lesions characterized by decreased perfusion. The left hemisphere was more frequently involved. None of the children with chronic tic disorder had a visible abnormality. Semi-quantitative analysis showed that, compared with children with chronic tic disorder, children with Tourette's syndrome had significantly lower perfusion in the left lateral temporal area and asymmetric perfusion in the dorsolateral frontal, lateral and medial temporal areas. In conclusion, using the visual approach, brain SPET perfusion imaging is sensitive and specific in differentiating Tourette's syndrome and chronic tic disorder. The perfusion difference between the two groups, demonstrated by semi-quantitative analysis, may be related more to the co-morbidity in Tourette's syndrome than to tics per se. (orig.)

    In this study, we identified a strain of lactic acid bacteria (LAB) that induces high levels of IL-10 production by immune cells, and evaluated the ability of the strain to suppress chronic inflammation and ameliorate metabolic disorders in in vitro and in vivo models. Among a collection of LAB strains, Lactobacillus plantarum strain OLL2712 (OLL2712) induced the highest levels of IL-10 production in mouse-derived dendritic cells and peritoneal macrophages. The anti-inflammatory effects of this strain were evaluated using a co-culture system comprising RAW 264.7 and 3T3-L1 cells. We also administered heat-killed OLL2712 to obese and type 2 diabetic KKAy mice for 3 wk to evaluate the in vivo effects of the strain. The OLL2712 significantly decreased the production of proinflammatory cytokines in vitro. Likewise, the administration of OLL2712 significantly suppressed proinflammatory cytokine levels in both the visceral adipose tissue and the serum of KKAy mice, and reduced serum triglyceride concentrations. The strain also alleviated oxidative stress and adrenaline levels in the serum of KKAy mice. On the other hand, Lactobacillus gasseri strain MEP222804 (a moderate IL-10 inducer) did not ameliorate the systemic inflammation and hyperlipidemia in KKAy mice. Our results suggest that treatment with strong IL-10-inducing LAB has the potential to ameliorate metabolic disorders by suppressing chronic inflammation in the host animal.

  11. 'Is she alive? Is she dead?' Representations of chronic disorders of consciousness in Douglas Coupland's Girlfriend in a Coma.

    Colbeck, Matthew

    2016-09-01

    Depictions of coma have come to dominate literary and filmic texts over the last half century, a phenomenon coinciding with advancements in medical technology that have led to remarkable increases in the survival rates of patients with chronic disorders of consciousness. Authors of coma fiction are preoccupied with the imagined subjective experience of coma, often creating complex, dream-like worlds from which the protagonist must escape if survival is to be achieved. However, such representations appear to conflict with medical case studies and patient narratives that reveal that most often survivors of coma have no recollection of the coma itself. Providing a close reading of Douglas Coupland's Girlfriend in a Coma (1998) against the context of medical literature and diagnoses, this article examines how the coma patient is represented, often depicting the realities of a prolonged vegetative state, in contrast with other popular representations of coma. It explores how the author develops a work of 'fantastic' fiction (a genre defined by the structuralist critic Tzvetan Todorov), using the condition of coma as a metaphor for a postmodern existential crisis, while simultaneously employing mimetic techniques that raise important medical, ethical and philosophical questions surrounding the ontological status of the comatose patient. It is argued that coma fiction, even in its misrepresentation of the condition, can help us to engage with and interrogate how we think about chronic disorders of consciousness, thereby providing a valuable insight into our attitudes towards illness and mortality.

A considerable proportion of patients report significant impairment in health-related quality of life caused by the severity of their tics and behavioral symptoms and require medical intervention. The most commonly used medications are antidopaminergic agents, which have been consistently shown to be effective for tic control, but are also associated with poor tolerability because of their adverse effects. The newer antipsychotic medication aripiprazole is characterized by a unique mechanism of action (D2 partial agonism, and over the last decade has increasingly been used for the treatment of tics. We conducted a systematic literature review to assess the available evidence on the efficacy and safety of aripiprazole in pediatric patients with Tourette syndrome and other chronic tic disorders (age range: 4–18 years. Our search identified two randomized controlled trials (involving 60 and 61 participants and ten open-label studies (involving between six and 81 participants. The majority of these studies used two validated clinician-rated instruments (Yale Global Tic Severity Scale and Clinical Global Impression scale as primary outcome measures. The combined results from randomized controlled trials and open-label studies showed that aripiprazole is an

    Prior study of the combination of clofarabine and high dose cytarabine with granulocyte colony-stimulating factor (G-CSF) priming (GCLAC) in relapsed or refractory acute myeloid leukemia resulted in a 46% rate of complete remission despite unfavorable risk cytogenetics. A multivariate analysis demonstrated that the remission rate and survival with GCLAC were superior to FLAG (fludarabine, cytarabine, G-CSF) in the relapsed setting. We therefore initiated a study of the GCLAC regimen in the upfront setting in a multicenter trial. The objectives were to evaluate the rates of complete remission (CR), overall and relapse-free survival (OS and RFS), and toxicity of GCLAC. Clofarabine was administered at 30 mg m(-2) day(-1) × 5 and cytarabine at 2 g m(-2) day(-1) × 5 after G-CSF priming in 50 newly-diagnosed patients ages 18-64 with AML or advanced myelodysplastic syndrome (MDS) or advanced myeloproliferative neoplasm (MPN). Responses were assessed in the different cytogenetic risk groups and in patients with antecedent hematologic disorder. The overall CR rate was 76% (95% confidence interval [CI] 64-88%) and the CR + CRp (CR with incomplete platelet count recovery) was 82% (95% CI 71-93%). The CR rate was 100% for patients with favorable, 84% for those with intermediate, and 62% for those with unfavorable risk cytogenetics. For patients with an antecedent hematologic disorder (AHD), the CR rate was 65%, compared to 85% for those without an AHD. The 60 day mortality was 2%. Thus, front line GCLAC is a well-tolerated, effective induction regimen for AML and advanced myelodysplastic or myeloproliferative disorders.

    Full Text Available Abstract Background In order to confirm therapeutic effects of topiramate on posttraumatic stress disorder (PTSD observed in a prior study, a new prospective, open-label study was conducted to examine acute responses in chronic, nonhallucinatory PTSD. Methods Thirty-three consecutive newly recruited civilian adult outpatients (mean age 46 years, 85% female with DSM-IV-diagnosed chronic PTSD, excluding those with concurrent auditory or visual hallucinations, received topiramate either as monotherapy (n = 5 or augmentation (n = 28. The primary measure was a change in the PTSD Checklist-Civilian Version (PCL-C score from baseline to 4 weeks, with response defined as a ≥ 30% reduction of PTSD symptoms. Results For those taking the PCL-C at both baseline and week 4 (n = 30, total symptoms declined by 49% at week 4 (paired t-test, P Conclusions Promising open-label findings in a new sample converge with findings of a previous study. The use of topiramate for treatment of chronic PTSD, at least in civilians, warrants controlled clinical trials.

    Philadelphia-negative myeloproliferative neoplasms (Ph-negative MPN) comprise a heterogeneous group of chronic hematologic malignancies. The quality of life, morbidity, and mortality of patients with MPN are primarily affected by disease-related symptoms, thromboembolic and hemorrhagic complications, and progression to myelofibrosis and acute leukemia. Major bleeding represents a common and important complication in MPN, and the incidence of such bleeding events will become even more relevant in the future due to the increasing disease prevalence and survival of MPN patients. This review discusses the causes, differential diagnoses, prevention, and management of bleeding episodes in patients with MPN, aiming at defining updated standards of care in these often challenging situations.

    Full Text Available Background: Eating disorders are associated with physical morbidity and appear to have causal factors like stressful life events and negative affect. Binge eating disorder (BED is characterized by eating in a discrete period of time a larger than normal amount of food, a sense of lack of control over eating, and marked distress. There are still unmet needs for the identification of mechanisms regulating excessive eating, which is in part due to the lack of appropriate animal models. We developed a naturalistic murine model of subordination stress induced hyperphagia associated with the development of obesity. Here we tested the hypotheses that the eating responses of subordinate mice recapitulate the BED and that limiting hyperphagia could prevent stress-associated metabolic changes. Methods: Adult male mice were exposed to a model of chronic subordination stress associated with the automated acquisition of food intake and we performed a detailed meal pattern analysis. Additionally, using a pair-feeding protocol was test the hypothesis that the manifestation of obesity and the metabolic syndrome could be prevented by limiting hyperphagia. Results: The architecture of feeding of subordinate mice was disrupted during the stress protocol due to disproportionate amount of food ingested at higher rate and with shorter satiety ratio than control mice. Subordinate mice hyperphagia was further exacerbated in response to either hunger or to the acute application of a social defeat. Notably, the obese phenotype but not the fasting hyperglycemia of subordinate mice was abrogated by preventing hyperphagia in a pair feeding paradigm. Conclusion: Overall these results support the validity of our chronic subordination stress to model binge eating disorder allowing for the determination of the underlying molecular mechanisms and the generation of testable predictions for innovative therapies, based on the understanding of the regulation and the control of food

    2012-01-01

    Full Text Available Chronic Myeloid Leukemia (CML is a myeloproliferative pluripotent stem cell disorder characterized by the presence of a cytogenetic hallmark, the Philadelphia (Ph chromosome, and accounts for 15% of adult leukemias. The disease progresses from a chronic phase through an accelerated phase to a blast phase and its natural course accounts for a median 4 years survival1. The Ph chromosome is derived by a reciprocal translocation termed t(9;22 in which the c-abl oncogene has moved from chromosome 9 into the breakpoint cluster region (bcr, within the bcr gene on chromosome 22, resulting in a chimeric bcr-abl fusion gene that encodes a 210 KD protein (p210 with constitutive tyrosine kinase activity. Two major alternative chimeric p210 can result from this fusion gene: p210-b2a2 where the junction occurs between bcr exon 2 (b2 and abl exon 2 (a2 and p210-b3a2 where the the junction occurs between bcr exon 3 (b3 and abl exon 2 (a2. About 40% of CML patients harbor the p210-b2a2 and about 60% of them show the p210-b3a2.

    Full Text Available Abstract Background There is little qualitative insight into how persons with chronic Whiplash-Associated Disorder cope on a day to day basis. This study seeks to identify the symptoms persons with Whiplash-Associated Disorder describe as dominating and explore their self-initiated coping strategies. Methods Qualitative study using focus groups interviews. Fourteen Norwegian men and women with Whiplash-Associated Disorder (I or II were recruited to participate in two focus groups. Data were analyzed according to a phenomenological approach, and discussed within the model of Cognitive Activation Theory of Stress (CATS. Results Participants reported neck and head pain, sensory hypersensitivity, and cognitive dysfunction following their whiplash injury. Based on the intensity of symptoms, participants divided everyday life into good and bad periods. In good periods the symptoms were perceived as manageable. In bad periods the symptoms intensified and took control of the individual. Participants expressed a constant notion of trying to balance their three main coping strategies; rest, exercise, and social withdrawal. In good periods participants experienced coping by expecting good results from the strategies they used. In bad periods they experienced no or negative relationships between their behavioral strategies and their complaints. Conclusions Neck and head pain, sensory hypersensitivity, and cognitive dysfunction were reported as participants' main complaints. A constant notion of balancing between their three main coping strategies; rest, exercise, and social withdrawal, was described.

  19. A Research Synthesis of Therapeutic Interventions for Whiplash-Associated Disorder (WAD: Part 4 – Noninvasive Interventions for Chronic WAD

    Full Text Available Whiplash-associated disorder (WAD represents a significant public health problem, resulting in substantial social and economic costs throughout the industrialized world. While many treatments have been advocated for patients with WAD, scientific evidence supporting their effectiveness is often lacking. A systematic review was conducted to evaluate the strength of evidence for various WAD therapies. Multiple databases (including Web of Science, EMBASE and PubMed were searched to identify all studies published from January 1980 through March 2009 that evaluated the effectiveness of any clearly defined treatment for acute (less than two weeks, subacute (two to 12 weeks or chronic (longer than 12 weeks WAD. The present article, the fourth in a five-part series, evaluates the evidence for noninvasive interventions initiated during the chronic phase of WAD. Twenty-two studies that met the inclusion criteria were identified, 12 of which were randomized controlled trials with ‘good’ overall methodological quality (median Physiotherapy Evidence Database score of 6. For the treatment of chronic WAD, there is evidence to suggest that exercise programs are effective in relieving whiplash-related pain, at least over the short term. While the majority of a subset of nine studies supported the effectiveness of interdisciplinary interventions, the two randomized controlled trials provided conflicting results. Finally, there was limited evidence, consisting of one supportive case series each, that both manual joint manipulation and myofeedback training may provide some benefit. Based on the available research, exercise programs were the most effective noninvasive treatment for patients with chronic WAD, although many questions remain regarding the relative effectiveness of various exercise regimens.

    Although attachment theory has become an influential approach used for the study of mental disorders, hitherto little has been known about the relation of attachment to somatoform disorders. In this study 15 patients with a somatoform pain disorder were compared with 15 non-clinical control participants. Attachment representations were measured by the Adult Attachment Interview (AAI). Compared to the control group, the patient group describes parental behavior as less loving and more rejecting, expresses more anger towards the mother, shows more signs of unresolved loss and trauma, and their interviews are markedly less coherent. None of the patients is classified as secure; the majority falls within the unresolved category. The findings of this study can contribute to a better understanding of the often described adversities in the therapeutic alliance with these patients.

    Mental health disorders(MHD) in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) have been widely studied. However, the underlying role of inflammatory cytokines and their associated signaling pathways have not been investigated. Here, we report the potential role of cytokines and associated signaling pathways in CP/CPPS patients with MHD and in a CP/CPPS animal model. CP/CPPS patients (n = 810) and control subjects (n = 992) were enrolled in this case-control multicenter study, and serum cytokine levels were measured. Male Sprague-Dawley rats received multiple intracutaneous injections of an immuno-agent along with a pertussis-diphtheria-tetanus triple vaccine for autoimmune CP/CPPS development. The results revealed that, in CP/CPPS patients with significant MHD, elevated IL-1α, IL-1β, IL-4, IL-13, and TNF-α serum levels were observed. The above five cytokines in CP/CPPS rats were significantly elevated in prostate tissue (p < 0.05), and IL-1β levels were elevated in serum and cerebrospinal fluid. In behavioral tests, CP/CPPS rats showed anxiety- and depression-like symptoms, and impaired spatial and associative memory performance (p < 0.05). In the CP/CPPS group, ERK1/2 phosphorylation levels were increased in the amygdala and nucleus accumbens, and decreased in the hippocampus, but not caudate nucleus. Thus, prostate-derived cytokines, especially IL-1β, cross the blood brain barrier and may lead to enhanced ERK1/2 signaling in several brain areas, possibly underlying induction of CP/CPPS-related MHD.

    2013-01-01

    Lysophosphatidylcholine (LPC) and lysophosphatidic acid (LPA), the most prominent lysoglycerophospholipids, are emerging as a novel class of inflammatory lipids, joining thromboxanes, leukotrienes and prostaglandins with which they share metabolic pathways and regulatory mechanisms. Enzymes that participate in LPC and LPA metabolism, such as the phospholipase A(2) superfamily (PLA(2)) and autotaxin (ATX, ENPP2), play central roles in regulating LPC and LPA levels and consequently their actions. LPC/LPA biosynthetic pathways will be briefly presented and LPC/LPA signaling properties and their possible functions in the regulation of the immune system and chronic inflammation will be reviewed. Furthermore, implications of exacerbated LPC and/or LPA signaling in the context of chronic inflammatory diseases, namely rheumatoid arthritis, multiple sclerosis, pulmonary fibrosis and hepatitis, will be discussed. This article is part of a Special Issue entitled Advances in Lysophospholipid Research.

  8. Clinical features of vascular disorders associated with chronic hepatitis virus infection.

    2014-01-01

    Hepatitis virus infections can be accompanied by extrahepatic manifestations that may be caused by the host's immune reaction to the viral infection. Vascular involvement is one of these manifestations and is occasionally associated with life-threatening conditions due to systemic organ failure. The unique profile of hepatitis-related vascular involvement is associated with infection by different types of hepatitis viruses. For example, polyarteritis nodosa is more frequently reported in patients with chronic hepatitis B than those with chronic hepatitis C. Similarly, membranous nephropathy is a notable manifestation among hepatitis B virus-positive patients. In contrast, patients infected with hepatitis C virus are at risk for cryoglobulinemia and membranoproliferative glomerulonephritis. Antiviral therapy is necessary to control these kinds of vasculitis related to hepatitis virus infections; however, immunosuppressive agents may be required to treat severe cases. New antiviral drugs for viral hepatitis could improve the prognosis of vascular and renal involvement.

    Chronic subclinical inflammation represents a risk factor of type 2 diabetes and several diabetes complications, including neuropathy and atherosclerosis including macro-vasculopathy and micro-vasculopathy. However, the inflammatory response in the diabetic wound was shown to be remarkably hypocellular, unregulated and ineffective. Advanced glycation end products (AGEs) and one of its receptors, RAGE, were involved in inducing chronic immune imbalance in diabetic patients. Such interactions attracts immune cell into diffused glycated tissue and activates these cells to induce inflammatory damage, but disturbs the normal immune rhythm in diabetic wound. Traditional measurements of AGEs are high-performance liquid chromatography and immunohistochemistry staining, but their application faces the limitations including complexity, cost and lack of reproducibility. A new noninvasive method emerged in 2004, using skin autofluorescence as indicator for AGEs accumulation. It had been reported to be informative in evaluating the chronic risk of diabetic patients. Studies have indicated therapeutic potentials of anti-AGE recipes. These recipes can reduce AGE absorption/de novo formation, block AGE-RAGE interaction and arrest downstream signaling after RAGE activation.

    A stable volume and composition of extracellular fluid are essential for normal functioning of the body. Since the kidney is primarily responsible for regulating extracellular fluid, loss of kidney function should have catastrophic consequences. Fortunately, even with loss of more than 90 percent of renal function, a remarkable capacity to regulate body fluid volumes and sodium and potassium persists. Nevertheless, this capacity is limited to chronic renal disease and this has important consequences for clinical management of these patients. How can sodium and potassium homeostasis be assessed? Methods for evaluating the steady-state regulation of sodium include measurement of body fluids and their distribution in different compartments and measurement of exchangeable and intracellular sodium. Short-term regulation of body sodium can be assessed from measurement of sodium balance during changes in dietary salt. Potassium is predominantly contained within cells and thus the assessment of its regulation requires special emphasis on measurement of steady-state body stores and potassium distribution across cell membranes. However, the methods used to make all of these measurements require assumptions that may not hold in the altered state of uremia. This raises problems in interpretation requiring critical analysis before conclusions can be made regarding sodium and potassium homeostasis in patients with chronic renal failure. This review focuses on abnormalities of body fluids, sodium and potassium in patients with creatinine clearances of less than 20 ml/min due to chronic renal failure and the impact of conservative therapy, dialysis and renal transplantation on these patients.

    The 8p11 myeloproliferative syndrome is a rare hematologic malignancy derived from a pluripotent hematopoietic stem cell associated with rearrangements involving the fibroblast growth factor receptor 1 (FGFR1) gene located on chromosome 8p11. The most common translocation, t(8;13) (p11;q13), results in a ZNF198-FGFR1 fusion gene and constitutively active FGFR1 tyrosine kinase activity. Typical pathologic findings include myeloid hyperplasia, lymphadenopathy, precursor T-lymphoblastic lymphoma, and eosinophilia. The disease is usually associated with an aggressive course and progression to acute myeloid leukemia is frequent. We report here the first case of 8p11 myeloproliferative syndrome in an infant and demonstrate the value of molecular testing in the diagnosis and minimal disease monitoring of this rare disease.

    Recovery management checkups (RMCs) for clients with substance use disorders reduce the time from relapse to treatment reentry, increase treatment retention, and improve long-term outcomes. The objectives of this article are to calculate and compare the economic costs of providing outcome monitoring (OM) only with those of providing OM + RMC to help understand the feasibility of disseminating this model more widely. We estimate the total and incremental costs of OM and OM + RMC using data from a recently completed randomized controlled trial with adult chronic substance users (N = 446). Adding RMC to OM increased total intervention costs by about 50% per person per year ($707 to $1,283) and quarter ($177 to $321). It cost an average of $834 to identify a person in relapse and $2,699 to identify, link, and retain them in treatment. The increased costs of RMC are modest relative to the substantial societal costs of chronic substance users returning to regular use, crime, and other risk behaviors.

    Currently, the lack of a universal and specific marker of clonality hampers the diagnosis and classification of chronic expansions of natural killer (NK) cells. Here we investigated the utility of flow cytometric detection of aberrant/altered NK-cell phenotypes as a surrogate marker for clonality, in the diagnostic work-up of chronic lymphoproliferative disorders of NK cells (CLPD-NK). For this purpose, a large panel of markers was evaluated by multiparametric flow cytometry on peripheral blood (PB) CD56(low) NK cells from 60 patients, including 23 subjects with predefined clonal (n = 9) and polyclonal (n = 14) CD56(low) NK-cell expansions, and 37 with CLPD-NK of undetermined clonality; also, PB samples from 10 healthy adults were included. Clonality was established using the human androgen receptor (HUMARA) assay. Clonal NK cells were found to show decreased expression of CD7, CD11b and CD38, and higher CD2, CD94 and HLADR levels vs. normal NK cells, together with a restricted repertoire of expression of the CD158a, CD158b and CD161 killer-associated receptors. In turn, NK cells from both clonal and polyclonal CLPD-NK showed similar/overlapping phenotypic profiles, except for high and more homogeneous expression of CD94 and HLADR, which was restricted to clonal CLPD-NK. We conclude that the CD94(hi)/HLADR+ phenotypic profile proved to be a useful surrogate marker for NK-cell clonality.

    2007-11-01

    Previous research documented the elevated risk of suicide and suicidal ideation among Vietnam veterans with post-traumatic stress disorder (PTSD). The aim of the current study was to examine which Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, PTSD symptom clusters are most associated with suicidal ideation in this population. Fifty Vietnam combat veterans enrolled in treatment for PTSD responded to the Beck Scale for Suicide Ideation and were interviewed with the Clinician-Administered PTSD Scale. In linear regression analysis, it was found that the reexperiencing symptom cluster was significantly associated with suicidal ideation but the other two symptom clusters (avoidance/numbing and increased arousal) were not. Furthermore, scores on a measure of severity of combat exposure were not found to be significantly related to PTSD symptoms or suicidal ideation. The results of this study suggest the importance of reexperiencing symptoms for predicting which individuals with combat-related PTSD are most at risk for suicidal ideation and behavior.

[Subjects and Methods] Two independent reviewers performed a computer-assisted search of the MEDLINE, SciELO, LILACS, and BIREME Virtual Health Library medical databases from their inception to November 2015. [Results] One thousand one hundred twenty-six articles were found that met the inclusion criteria. Articles were excluded if they were not in English, the patients did not undergo HD, or the studies were not cross-sectional or clinical trials. After reading the full text, a further 300 studies were excluded because they did not use polysomnography. The remaining 18 studies with ESRD patients undergoing HD comprised 8 clinical trials and 10 cross-sectional studies. This systematic review followed the criteria outlined by the PRISMA declaration. [Conclusion] In this systematic review, a high prevalence of sleep disorders was observed in ESRD, including sleep-disordered breathing. This knowledge may enable health professionals to devise new strategies for the diagnosis and treatment of these patients, in order to reduce morbidity and mortality and improve their quality of life.

    Chronic myeloid leukemia is rare in pregnancy with an estimated incidence of 1:75000. It is a genetic myeloproliferative disorder marked by increased and unregulated growth of myeloid cells in the bone marrow. The terminal phase of chronic myeloid leukemia may develop into a blast crisis, defined as >30% myeloblasts in the circulation. A blast crisis resembles an acute leukemia and is associated with rapid clinical deterioration and short survival. Targeted gene therapy with tyrosine kinase inhibitors is effective in treatment but when these agents are discontinued, as in pregnancy, the patient may relapse and blast cells may enter the circulation. Theoretically, a central nervous system blast crisis may be induced by inadvertent intrathecal seeding of circulating blast cells, and is associated with a high mortality rate and a median life expectancy of three months. We describe the anesthetic management of a patient with chronic myeloid leukemia and blast cells in the circulation who required cesarean delivery. After considering the potential anesthetic risks and benefits, general anesthesia was chosen. Although an iatrogenic central nervous system blast crisis is extremely rare, the high morbidity and mortality associated with such an event should be considered when formulating an anesthetic plan.

    Only a select number of studies have examined different forms of child maltreatment in complex dissociative disorders (DDs) in comparison to other groups. Few of these have used child abuse-related chronic posttraumatic stress disorder (C-PTSD) and mixed psychiatric (MP) patients with maltreatment as comparison groups. This study examined child sexual, physical, and emotional abuse as well as physical and emotional neglect in DD (n = 39), C-PTSD (n = 13), and MP (n = 21) samples, all with abuse and neglect histories. The predictive capacity of these different forms of maltreatment across the 3 groups was assessed for pathological dissociation, shame, guilt, relationship esteem, relationship anxiety, relationship depression, and fear of relationships. All forms of maltreatment differentiated the DD from the MP group, and sexual abuse differentiated the DD sample from the C-PTSD group. Childhood sexual abuse was the only predictor of pathological dissociation. Emotional abuse predicted shame, guilt, relationship anxiety, and fear of relationships. Emotional neglect predicted relationship anxiety and relationship depression. Physical neglect was associated with less relationship anxiety. Different forms of abuse and neglect are associated with different symptom clusters in psychiatric patients with maltreatment histories.

  8. Chronic stress and brain plasticity: mechanisms underlying adaptive and maladaptive changes and implications for stress-related CNS disorders

    Stress responses entail neuroendocrine, autonomic, and behavioral changes to promote effective coping with real or perceived threats to one’s safety. While these responses are critical for the survival of the individual, adverse effects of repeated exposure to stress are widely known to have deleterious effects on health. Thus, a considerable effort in the search for treatments to stress-related CNS disorders necessitates unraveling the brain mechanisms responsible for adaptation under acute conditions and their perturbations following chronic stress exposure. This paper is based upon a symposium from the 2014 International Behavioral Neuroscience Meeting, summarizing some recent advances in understanding the effects of stress on adaptive and maladaptive responses subserved by limbic forebrain networks. An important theme highlighted in this review is that the same networks mediating neuroendocrine, autonomic, and behavioral processes during adaptive coping also comprise targets of the effects of repeated stress exposure in the development of maladaptive states. Where possible, reference is made to the similarity of neurobiological substrates and effects observed following repeated exposure to stress in laboratory animals and the clinical features of stress-related disorders in humans.

    Background and aim In spite of numerous interventions, the control of mineral disturbances remains poor in end-stage renal failure (ESRF) patients. Chronic kidney disease - mineral and bone disorders (CKD-MBD) represent an important cause of mortality and morbidity. The aim of this study is to analyze the relationship between mineral and bone disorders (MBD) and their components impact on all-cause mortality and cardiovascular (CDV) mortality and morbidity in chronic dialysis patients. Methods This prospective study was carried out in a cohort of 92 randomly selected patients with ESRF treated with hemodialysis (HD) and peritoneal dialysis (PD). The data regarding demographic and clinical characteristics were recorded, including vascular disease (coronary, cerebral, peripheral). The follow-up lasted 40 months and the final evaluation included the number and causes of deaths, CDV events and disease. Serum Ca, P, ALP, iPTH, albumin, cholesterol, urea and creatinine levels were measured. The plain radiographic films of hands and pelvis evaluated all bone abnormalities suggestive of renal osteodystrophy (ROD) and peripheral vascular calcification (VC). Results All-cause annual mortality represented 9.25% in HD and 9.09% in PD patients. The CDV mortality represented almost 44% in HD patients and 66% in PD patients from all deaths. There was a high prevalence of CDV diseases and events. High and low serum P levels were associated with a worse survival rate. Hypercalcaemia was associated with high risk for CDV events in HD patients. In PD patients, the relationship between increased ALP levels and all-cause mortality was significant. Other mineral markers were not predictive of the outcome in the studied patients. In the HD patients the severity of VC was associated with all-cause and CDV mortality, and with CDV events. Male gender, hypercholesterolemia, decreased URR, albumin and creatinine were identified as risk factors for all-cause mortality. The diabetics had higher

    A number of anti-tumor necrosis factor alpha (TNF-α) biologics have been developed in recent years, such as adalimumab, etanercept, and infliximab for the treatment of chronic inflammatory disorders like rheumatoid arthritis (RA), inflammatory bowel disease (IBD), and psoriasis and several other...... novel drugs that target TNF-α signaling are still being developed. Indeed, blockade of this pathway seems so important amongst immune-targets that TNF-α targeted therapies will continue to have a significant role in the treatment of chronic inflammation. However, up to 40% of RA and IBD patients do...... concentrations of TL1A has been demonstrated in patients with various chronic inflammatory disorders. Here, we describe the current knowledge of TL1As immunobiology and present results from human disease, animal models, and pre-clinical intervention studies that point toward development of anti-TL1A therapy...

  11. The gut microbiome, diet, and links to cardiometabolic and chronic disorders.

    2016-03-01

    Cardiometabolic diseases (CMDs) have been associated with changes in the composition of the gut microbiota, with links between the host environment and microbiota identified in preclinical models. High-throughput sequencing technology has facilitated in-depth studies of the gut microbiota, bacterial-derived metabolites, and their association with CMDs. Such strategies have shown that patients with CMDs frequently exhibit enrichment or depletion of certain bacterial groups in their resident microbiota compared to healthy individuals. Furthermore, the ability to transfer resident gut microbiota from mice or humans into germ-free mouse models, or between human patients, has enabled researchers to characterize the causative role of the gut microbiota in CMDs. These approaches have helped identify that dietary intake of choline, which is metabolized by the gut microbiota, is associated with cardiovascular outcomes in mice and humans. Trimethylamine N-oxide (TMAO) - a metabolite derived from the gut microbiota - is also associated with poor cardiovascular outcomes in patients with cardiovascular disease and is elevated in patients with chronic kidney disease (CKD). TMAO might represent a biomarker that links the environment and microbiota with CKD. This Review summarizes data suggesting a link between the gut microbiota and derived metabolites with food intake patterns, metabolic alterations, and chronic CMDs.

    Full Text Available The authors describe the case of a 62 year old woman without any significant personal or family psychiatric history prior to being 52, when after a minor head trauma occurring during worktime, she started showing delusional ideas of hypochondri- ac and somatic content believing to have developed a “problem in the head”. Two years later she was admitted to a Psychiatric inpatient unit and diagnosed with a delusional disorder of the somatic subtype. At discharge she maintained the delusional ideas, which, however, were encapsulated from her personality and quiescent, while exhibiting no insight into her psychopatho- logical state. Very shortly thereafter, at follow-up in the outpatient clinic, she stopped all drug therapy (oral antipsychotic drugs. One year later, she was readmitted to the inpatient unit upon worsening of the hypochondriac and somatic delusional ideas. The prescribed medication was switched to depot injection, which she also stopped shortly thereafter. Three years later, being 58 years of age, she began to show manic symptoms of crescendo severity (grandiose delusion-like ideas, elated mood, overactivity, disinhibition, acceleration of thinking, reduced need for sleep and increased pres- sure of speech. This clinical condition gets worse, with persecutory delusional ideas and complex auditory hallucinations and she was admitted to the inpatient unit once more. This time she presents a full manic episode and a Bipolar I affective disorder diagnosis was made. She had a hyperthymic pre-morbid temperament. For the next 4 years, the patient remained somewhat stable with elation of mood, grandiose ideas, increased pressure of speech, eccen- tric clothing and lack of insight to her psychopathological state. Since the beginning of follow up, the patient always kept poor treatment compliance. The authors discuss the evolution and clinical significance of a particular and infrequent type of Bipolar Disorder, chronic mania.

    This initial study examined the nature, incidence, and clinical correlates of family accommodation in youth with tic disorders, and validated a brief self-report measure of tic-related family accommodation, the Tic Family Accommodation Scale (TFAS). Seventy-five youth aged 6-18 who were diagnosed with a tic disorder and their parent completed a diagnostic clinical interview, and clinician and parent-report measures of tic severity, depressive symptoms, anxiety symptoms, behavioral problems, family accommodation and impairment. An exploratory factor analysis of the TFAS showed a two-factor structure, with good internal consistency for the Total score, Modification of Child Environment and Modification of Parent Environment subscales (α = 0.88, 0.86, and 0.81, respectively). Family accommodation was not associated with tic severity. Family accommodation was associated with increased anxiety and depressive symptoms, higher externalizing, rule breaking, aggressive behaviors and social problems, and with greater tic-related functional impairment. Anxiety and externalizing problems (but not depressive symptoms) predicted family accommodation when controlling for tic severity. Family accommodation predicted high levels of functional impairment over and above the effect of tic severity, anxiety, depression and externalizing problems. Family accommodation is a common phenomenon for youth with tic disorders, with modifications typically encompassing changes to the child and/or parent environments. Accommodation was not associated with tic severity, but was related to higher levels of anxiety, depressive symptoms, externalizing symptoms, aggression, and rule breaking behaviors. Results suggest that other emotional symptoms are more likely to drive accommodation practices than the tic symptoms per se.

    Because posttraumatic stress disorder (PTSD) is both prevalent and underrecognized, routine primary care-based screening for PTSD has been implemented across the Veterans Health Administration. PTSD is frequently complicated by the presence of comorbid chronic pain, and patients with both conditions have increased symptom severity and poorer prognosis. Our objective was to determine whether the presence of pain affects diagnosis and treatment of PTSD among Department of Veterans Affairs (VA) patients who have a positive PTSD screening test. This retrospective cohort study used clinical and administrative data from six Midwestern VA medical centers. We identified 4,244 VA primary care patients with a positive PTSD screen and compared outcomes for those with and without a coexisting pain diagnosis. Outcomes were three clinically appropriate responses to positive PTSD screening: (1) mental health visit, (2) PTSD diagnosis, and (3) new selective serotonin reuptake inhibitor (SSRI) prescription. We found that patients with coexisting pain had a lower rate of mental health visits than those without pain (hazard ratio: 0.889, 95% confidence interval: 0.821-0.962). There were no significant differences in the rate of PTSD diagnosis or new SSRI prescription between patients with and without coexisting pain.

    Mg and its alloys have been considered as one of the most promising biodegradable medical devices, but it was still unclear whether hypermagnesemia involved health risks would occur in persons with kidney disease due to their deteriorated kidney function for Mg ions excretion from their body. In this study, we established a chronic renal failure (CRF) model in rats induced by adenine administration prior to Mg implantation, aiming to predict if CRF patients are suitable for the use of Mg implants. The results showed that Mg levels in serum, urine, feces and internal organs had no significant changes after Mg implantation for both normal and CRF rats. Biochemical indices detection and histopathological analysis in kidney, liver and heart tissue confirmed that Mg implants did not induce any extra damage in animals even with renal failure. Our study indicates that Mg based orthopaedic medical device may be considered for use in CRF patients without biosafety concerns.

    Full Text Available AIM: Neurological disorders (NDs occur commonly in children in our environment. Increasingly, the poor knowledge of these conditions among parents results in negative attitude with stress and disruption in interpersonal relationships. The objective of this study was to assess the level of stress and quality of marital relationships among mothers of children with NDs. METHOD: Between January and December 2008, 126 mothers of children with NDs at the Child and Adolescent Psychiatric clinic, University of Uyo Teaching Hospital were assessed for perceived stress, attitude and quality of marital relationships using PSQ and GRIMS Questionnaires. This was compared with mothers of normal children. RESULTS: There were prevalent negative attitudes among respondents in both groups; only 15 (13.2% mothers with NDs and 6 (5.3% controls attributed causes to medical conditions; 10 (7.9% against 26 (22.8% wished the child had died. Stress was high in mothers aged below 30 and 50 years and above; with tertiary education and in those who were self–employed (p<0.001. Quality of marital relationship was poorer in subjects than controls (p<0.001. CONCLUSION: Mothers of children with neurological disorders have increased stress resulting in poor interpersonal relationships. Education is important to improve parental knowledge and enhance family cohesion. [TAF Prev Med Bull 2010; 9(5.000: 413-420

    2014-01-01

    The present study aims to describe a case of work injury and occupational disease which is unique for the type of disease diagnosed, conditions of onset and mode of management by INAIL (Italian National Institute of Insurance for Injuries at Work and Occupational Diseases). A worker, after a verbal animated dispute with some collegues and superiors, had an acute psychiatric agitation attack and went to the nearest emergency room, where he was subjected to clinical exams. No neuropsychiatric alteration was found, but the physicians diagnosed an anxiety crisis reactive to the work environment. Consequently, the medical certificate for work injury was edited and sent to INAIL. The worker has been off work for 110 days because of a anxious and depressive syndrome, due to the verbal conflict. In a later assessment, INAIL recognized only the first 30 days of the employee's time off as injury at work, while judging the following period off work as related to affectivity disturbance due to common disease, not related to work environment. The following year, "anxious-depressive syndrome" is worsened and attributed by the same worker to the recurrence of acts of persecution and discrimination against him at work. For this reason he applied for recognition of occupational disease diagnosed as "Chronic Adjustment Disorder with prolonged depressive reaction and somatic anxiety, which developed into a protracted conflict marked the employment situation". INAIL rejected that request, but in the same year the employee has submitted the complaint for "mobbing". Even this request was rejected. Literature shows many examples of traumatic events during working activities which cause psychiatric disturbances. These events include industrial disasters, explosions, transport and mining accidents, accidents in psychiatric units with high risks of assaults, armed conflicts, war, assault and sexual assault, natural disasters. Victims show symptoms of acute stress disorder (ASD) or post

    The relationship between orbitofrontal cortex (OFC) volumes and functional domains in treatment-resistant patients with schizophrenia or schizoaffective disorder is poorly understood. OFC dysfunction is implicated in several of the behaviors that are abnormal in schizophrenia. However, little is known about the relationship between these behaviors and OFC volumes. Forty-nine patients received magnetic resonance imaging scanning as part of a double-blind treatment study in which psychiatric symptomatology, neuropsychological function, and aggression were measured. OFC volumes were manually traced on anatomical images. Psychiatric symptomatology was measured with the Positive and Negative Syndrome Scale (PANSS). Aggression was measured with the Overt Aggression Scale (OAS) and with the PANSS. Neuropsychological function was assessed using a comprehensive test battery. Larger right OFC volumes were associated with poorer neuropsychological function. Larger left OFC gray matter volumes and larger OFC white matter volumes bilaterally were associated with greater levels of aggression. These findings are discussed in the context of potential iatrogenic effects.

    Despite being a canonical presenting feature of mitochondrial disease, the genetic basis of progressive external ophthalmoplegia remains unknown in a large proportion of patients. Here we show that mutations in SPG7 are a novel cause of progressive external ophthalmoplegia associated with multiple mitochondrial DNA deletions. After excluding known causes, whole exome sequencing, targeted Sanger sequencing and multiplex ligation-dependent probe amplification analysis were used to study 68 adult patients with progressive external ophthalmoplegia either with or without multiple mitochondrial DNA deletions in skeletal muscle. Nine patients (eight probands) were found to carry compound heterozygous SPG7 mutations, including three novel mutations: two missense mutations c.2221G>A; p.(Glu741Lys), c.2224G>A; p.(Asp742Asn), a truncating mutation c.861dupT; p.Asn288*, and seven previously reported mutations. We identified a further six patients with single heterozygous mutations in SPG7, including two further novel mutations: c.184-3C>T (predicted to remove a splice site before exon 2) and c.1067C>T; p.(Thr356Met). The clinical phenotype typically developed in mid-adult life with either progressive external ophthalmoplegia/ptosis and spastic ataxia, or a progressive ataxic disorder. Dysphagia and proximal myopathy were common, but urinary symptoms were rare, despite the spasticity. Functional studies included transcript analysis, proteomics, mitochondrial network analysis, single fibre mitochondrial DNA analysis and deep re-sequencing of mitochondrial DNA. SPG7 mutations caused increased mitochondrial biogenesis in patient muscle, and mitochondrial fusion in patient fibroblasts associated with the clonal expansion of mitochondrial DNA mutations. In conclusion, the SPG7 gene should be screened in patients in whom a disorder of mitochondrial DNA maintenance is suspected when spastic ataxia is prominent. The complex neurological phenotype is likely a result of the clonal

    Objective To determine the prevalence of sleep-disordered breathing in patients with stable, optimally treated chronic congestive heart failure and the effect of short-term oral theophylline therapy on periodic breathing in these patients.Methods Patients with stable, optimally treated chronic congestive heart failure were monitored by polysomnography during nocturnal sleep. The effects of theophylline therapy on periodic breathing associated with stable heart failure were observed before and after treatment.Results Patients were divided into two groups. GroupⅠ(n=21) consisted of individuals with 15 episodes of apnea and hypopnea [as determined by the apnea-hypopnea index (AHI)] per hour or less; Group Ⅱ (n=15, 41.7%) individuals had an index of more than 15 episodes per hour. In group Ⅱ, the AHI varied from 16.8 to 78.8 (42.6±15.5) in which the obstructive AHI was 11.1±8.4 and the central AHI was 31.5±9.6. Group Ⅱ had significantly more arousals (36.8±21.3 compared with 19.4±11.2 in group Ⅰ) that were directly attributable to episodes of apnea and hypopnea, lower arterial oxyhemoglobin saturation (76.7%±4.6% compared with 86.5%±2.8%) and lower left ventricular ejection fraction (24.2%±8.8% compared with 31.5%±10.6%). Thirteen patients with compensated heart failure and periodic breathing received theophylline orally (at an average dose of 4.3 mg/kg) for five to seven days. After treatment, the mean plasma theophylline concentration was (11.3±2.5) μg/ml. Theophylline therapy resulted in significant decreases in the number of AHI (20.8±13.2 vs. 42.6±15.5; P<0.001) and the number of episodes of central apnea-hypopnea per hour (10.1±7.6 vs. 31.5±9.6; P<0.001). Furthermore, the percentage of total sleep time during which arterial oxyhemoglobin saturation (SaO2) was less than 90 percent (8.8%±8.6% vs. 23.4%±24.1%; P<0.05) and the arousals per hour (18.7±21.2 vs. 36.8±21.3; P<0.05) were also lower. There were no significant differences in the

    Background: Mineral and bone disorder (MBD), especially hyperphosphatemia, is an independently risk factor for adverse prognosis in patients with chronic kidney disease (CKD). However, CKD-MBD among Chinese population was poorly studied. This study aimed to investigate the status of MBD and its association with cardiovascular parameters in Chinese patients with predialysis CKD. Methods: Chinese Cohort Study of Chronic Kidney Disease (C-STRIDE) is a prospective multicenter cohort study involving predialysis CKD patients in China. Markers of MBD, including serum phosphorus, calcium, and intact parathyroid hormone, were measured in baseline samples at the patients’ entry. The association between serum phosphorus and abdominal aortic calcification (AAC), left ventricular hypertrophy (LVH) were examined by logistic regression models. Results: Altogether 3194 predialysis patients with mean estimated glomerular filtration of 51.8 ± 33.1 ml·min−1.1.73 m−2 were included. The proportion of patients with hyperphosphatemia were 2.6%, 2.9%, 6.8%, and 27.1% in CKD Stages 3a, 3b, 4, and 5, respectively. Moreover, 71.6% of the patients with hyperphosphatemia did not receive any phosphate-binder (PB). Lateral abdominal X-rays were obtained in 2280 patients, 9.8% of the patients were diagnosed as having AAC. Altogether 2219 patients had data of echocardiography, and 13.2% of them were diagnosed with LVH. Multivariate logistic regression analysis showed that serum phosphorus was independently associated with the presence of AAC and LVH. Conclusions: In Chinese patients with CKD, the percentage of hyperphosphatemia is comparable to that of other countries while the usage of PBs is suboptimal. The prevalence of vascular calcification in Chinese patients is relatively lower compared with the Caucasian population. PMID:27647184

    The growing population of elderly with chronic kidney disease (CKD) is at greater risk for cardiovascular disease given an independent risk of CKD, as well as from added dyslipidemia of aging and renal dysfunction. Changes in lipid metabolism with more isodense and high-dense, triglyceride-rich particles, low high-density lipoprotein cholesterol, and increased triglyceride levels occur with CKD and aging, which are noted to have significant atherogenic potential. In addition, lipid abnormalities may lead to the progression of CKD. Cardiovascular mortality in the end-stage renal disease population is more than 10 times higher than the general population. Treatment of dyslipidemia in the general population suggests important benefits both in reducing cardiovascular risk and in the prevention of cardiovascular disease. Secondary analyses of elderly subgroups of various large prospective studies with statins suggest treatment benefit with statin use in the elderly. Similarly limited data from secondary analyses of CKD subgroups of larger prospective trials using statins also suggest a possible benefit in cardiovascular outcomes and the progression of kidney disease. However, randomized trials have yet to confirm similar benefits and targets of treatment for dyslipidemia in the elderly with CKD and end-stage renal disease. Treatment in the elderly with CKD should be individualized and outweigh risks of side effects and drug-drug interactions. There is a need for further specific investigation of dyslipidemia of CKD in the aging population in relation to renal disease progression and cardiovascular outcome.

    1978-01-01

    The present paper reports on 12 patients (8 males, 4 females) suffering from chronic decompensated respiratory failure, who presented concomitant transient haemodynamic disturbances in the carotid and vertebrobasilary systems, manifested by hemisphere or brain stem symptoms. Owing to the adaptive capacity of these patients there exists a certain tolerance threshold to hypercapnic hypoxemia, but following accentuated or rapid aggravation of acid-base hypercapnic hypoxemia, the biological balance is abruptly perturbed leading to cerebral haemodynamic disturbances. The pathophysiological mechanism of production appears to be the accumulation of acid ions caused by pH acidification of the cerebrospinal fluid. Increase in the cerebral arterial output with decrease in the rate of circulation and vascular resistance take place especially in the vessels with atheromatous or hyaline lesions. Under conditions of severe acidosic hypercapnic hypoxemia this, nevertheless, insures a minimum of 10--20% oxygen required by the metabolism of the nerve cell, sufficient for maintaining the structure of the cell (vita minima). These vasculometabolic mechanisms explain why with improvement of haematosis, following remission of the decompensated disease and fall in acidotic hypercapnic hypoxemia values, the cerebral haemodynamic disturbances also show a more or less evident remission because the nerve cells having maintained their structure are able to take up their function again.

    The present study examined long-term mental health outcomes following a major disaster, including the relative risks (RR) of developing psychiatric disorders. Trauma exposure and predisaster vulnerability factors were examined as predictors of chronic psychopathology. Standardized questionnaires measuring psychological distress were completed 5½ months, 14 months, 5 years, and 27 years after the disaster. Twenty seven years after the disaster, 48 (79%) survivors and a matched comparison group of 62 (78%) nondisaster-exposed controls were assessed using the Structured Clinical Interview for DSM-IV, axis I Disorders. The prevalence of posttraumatic stress disorder among the survivors was 6.1%, and the risk of having a psychiatric disorder was more than 3 times higher than in the comparison group (RR = 3.44, 95% confidence interval = 1.6-7.6). Disaster exposure and general neurotic personality predicted chronic psychopathology, which was reported by 20.9% of the participants. Findings from this study suggest that increased risk of psychopathology persists 27 years after disaster. Both disaster exposure and vulnerable personality are important predictors of chronic psychopathology.

    2015-01-01

    Background: Eating disorders are associated with physical morbidity and appear to have causal factors like stressful life events and negative affect. Binge-eating disorder (BED) is characterized by eating in a discrete period of time a larger than normal amount of food, a sense of lack of control over eating, and marked distress. There are still unmet needs for the identification of mechanisms regulating excessive eating, which is in part due to the lack of appropriate animal models. We developed a naturalistic murine model of subordination stress-induced hyperphagia associated with the development of obesity. Here, we tested the hypotheses that the eating responses of subordinate mice recapitulate the BED and that limiting hyperphagia could prevent stress-associated metabolic changes. Methods: Adult male mice were exposed to a model of chronic subordination stress (CSS) associated with the automated acquisition of food intake and we performed a detailed meal pattern analysis. Additionally, using a pair-feeding protocol we tested the hypothesis that the manifestation of obesity and the metabolic syndrome could be prevented by limiting hyperphagia. Results: The architecture of feeding of subordinate mice was disrupted during the stress protocol due to disproportionate amount of food ingested at higher rate and with shorter satiety ratio than control mice. Subordinate mice hyperphagia was further exacerbated in response to either hunger or to the acute application of a social defeat. Notably, the obese phenotype but not the fasting hyperglycemia of subordinate mice was abrogated by preventing hyperphagia in a pair-feeding paradigm. Conclusion: Overall, these results support the validity of our CSS to model BED allowing for the determination of the underlying molecular mechanisms and the generation of testable predictions for innovative therapies, based on the understanding of the regulation and the control of food intake.

    Neurotrophic factors are considered as part of the therapeutic strategy for neurological disorders like dementia, stroke and traumatic brain injury. Cerebrolysin is a neuropeptide preparation which mimics the action of endogenous neurotrophic factors on brain protection and repair. In dementia models, Cerebrolysin decreases β-amyloid deposition and microtubule-associated protein tau phosphorylation by regulating glycogen synthase kinase-3β and cyclin-dependent kinase 5 activity, increases synaptic density and restores neuronal cytoarchitecture. These effects protect integrity of the neuronal circuits and thus result in improved cognitive and behavioral performance. Furthermore, Cerebrolysin enhances neurogenesis in the dentate gyrus, the basis for neuronal replacement therapy in neurodegenerative diseases. Experimental studies in stroke animal models have shown that Cerebrolysin stabilizes the structural integrity of cells by inhibition of calpain and reduces the number of apoptotic cells after ischemic lesion. Cerebrolysin induces restorative processes, decreases infarct volume and edema formation and promotes functional recovery. Stroke-induced neurogenesis in the subventricular zone was also promoted by Cerebrolysin, thus supporting the brain's self-repair after stroke. Both, traumatic brain and spinal cord injury conditions stimulate the expression of natural neurotrophic factors to promote repair and regeneration processes -axonal regeneration, neuronal plasticity and neurogenesis- that is considered to be crucial for the future recovery. Neuroprotective effects of Cerebrolysin on experimentally induced traumatic spinal cord injury have shown that Cerebrolysin prevents apoptosis of lesioned motoneurons and promotes functional recovery. This section summarizes the most relevant data on the pharmacology of Cerebrolysin obtained from in vitro assays (biochemical and cell cultures) and in vivo animal models of acute and chronic neurological disorders.

    Recent clinical research has suggested that single working mothers may differ in their response to health treatment and outcomes, relative to their married female or male counterparts. The present study explored, on an a priori basis, the existence and extent of differences in chronic pain rehabilitation outcomes of pain report, return-to-work and future health utilization for single working mothers, relative to other patients. A cohort of 1,679 consecutive chronically disabled work related spinal disorder (CDWRSD) patients were placed into one of eight groups as a function of gender, marital status (single/married), and parenthood (with/without children). All patients completed an assessment battery measuring psychosocial variables at pre- and post-treatment, and a structured clinical interview evaluating socioeconomic outcomes at 1 year following completion of a 5-7 week functional restoration program. Results revealed that single females with children differed from all other groups in racial representation, with 57.1% of these individuals being African American, widely disparate from the prevailing local ethnicity. Single females and males with children were represented by a higher incidence of cervical injuries (25.0% and 26.7%, respectively) than all other groups (5.4-16.6%, p single females with children group did display greater levels of depression pre-treatment compared to the other groups. However, at post-treatment, these differences no longer existed. This investigation is one of the first to examine if the combination of gender and parenthood distinguishes significantly among CDWRSD patients. Overall, contrary to expectation, the single mothers did not show any significant differences in CDWRSD outcome at one-year post-rehab follow-up, and the single mothers and fathers showed no differences in depression or pain severity post-treatment. Thus, in spite of the societal belief to the contrary, it seems that single parent patients can show similar chronic

    The psychological dysfunctions that may underlie catatonia-like deterioration in autism spectrum disorders are discussed. Clinical observation suggests that an important factor is ongoing stress. The evidence for this from research and clinical observation is considered. The lack of evidence concerning the most appropriate medical treatments is discussed. A psychological approach designed for individual needs by relevant professionals and applied by parents and/or caregivers is described. This can be helpful whether or not medical treatments are used. It involves detailed holistic assessment of the individual and their circumstances to highlight possible precipitating stress factors in view of their underlying autism and cognitive/psychological functioning. The overall aim of this approach is to restructure the individual's lifestyle, environment and resolve cognitive/psychological factors to reduce the stress. An eclectic approach is used to find individual strategies in order to provide external goals and stimulation to increase motivation and keep the person engaged and active in meaningful and enjoyable pursuits. The approach describes ways of using verbal and physical prompts as external stimuli to overcome the movement difficulties and emphasizes maintaining a predictable structure and routine for each day. The importance of educating caregivers and service providers to understand the catatonia-like behavior is emphasized. Advice is given on management of specific problems such as incontinence, freezing in postures, eating problems, and episodes of excitement.

    BACKGROUND: Chronic orthostatic intolerance (COI) is a debilitating autonomic condition in young adults. Its neurohumoral and hemodynamic profiles suggest possible alterations of postural sympathetic function and of baroreflex control of heart rate (HR). METHODS AND RESULTS: In 16 COI patients and 16 healthy volunteers, intra-arterial blood pressure (BP), ECG, central venous pressure (CVP), and muscle sympathetic nerve activity (MSNA) were recorded at rest and during 75 degrees tilt. Spectral analysis of RR interval and systolic arterial pressure (SAP) variabilities provided indices of sympathovagal modulation of the sinoatrial node (ratio of low-frequency to high-frequency components, LF/HF) and of sympathetic vasomotor control (LFSAP). Baroreflex mechanisms were assessed (1) by the slope of the regression line obtained from changes of RR interval and MSNA evoked by pharmacologically induced alterations in BP and (2) by the index alpha, obtained from cross-spectral analysis of RR and SAP variabilities. At rest, HR, MSNA, LF/HF, and LFSAP were higher in COI patients, whereas BP and CVP were similar in the two groups. During tilt, BP did not change and CVP fell by the same extent in the 2 groups; the increase of HR and LF/HF was more pronounced in COI patients. Conversely, the increase of MSNA was lower in COI than in control subjects. Baroreflex sensitivity was similar in COI and control subjects at rest; tilt reduced alpha similarly in both groups. CONCLUSIONS: COI is characterized by an overall enhancement of noradrenergic tone at rest and by a blunted postganglionic sympathetic response to standing, with a compensatory cardiac sympathetic overactivity. Baroreflex mechanisms maintain their functional responsiveness. These data suggest that in COI, the functional distribution of central sympathetic tone to the heart and vasculature is abnormal.

    Although numerous recent publications have demonstrated interest in multiparameter flow cytometry in the investigation of myelodysplastic disorders, it is perceived by many laboratory hematologists as difficult and expensive, requiring a high level of expertise. We report a multicentric open real-life study aimed at evaluating the added value of the technically simple flow cytometry score described by the Ogata group for the diagnosis of myelodysplastic syndromes. A total of 652 patients were recruited prospectively in four different centers: 346 myelodysplastic syndromes, 53 myelodysplastic/myeloproliferative neoplasms, and 253 controls. The Ogata score was assessed using CD45 and CD34 staining, with the addition of CD10 and CD19. Moreover, labeling of CD5, CD7 and CD56 for the evaluation of myeloid progenitors and monocytes was tested on a subset of 294 patients. On the whole series, the specificity of Ogata score reached 89%. Respective sensitivities were 54% for low-risk myelodysplastic syndromes, 68% and 84% for type 1 and type 2 refractory anemia with excess of blasts, and 72% for myelodysplastic/myeloproliferative neoplasms. CD5 expression was poorly informative. When adding CD56 or CD7 labeling to the Ogata score, sensitivity rose to 66% for low-risk myelodysplastic syndromes, to 89% for myelodysplastic/myeloproliferative neoplasms and to 97% for refractory anemia with excess of blasts. This large multicenter study confirms the feasibility of Ogata scoring in routine flow cytometry diagnosis but highlights its poor sensitivity in low-risk myelodysplastic syndromes. The addition of CD7 and CD56 in flow cytometry panels improves the sensitivity but more sophisticated panels would be more informative.

    Full Text Available Graduated compression devices are considered the standard care for management of venous and lymphatic disorders. Recently compression devices exerting a pressure over the calf higher than over the ankle have been proved to be more effective than traditional graduated devices in increasing the impaired ejection fraction (EF from the lower leg in patients with venous disease. Aim of this work is presenting an overview of the new concept on progressive compression, its potential benefits and limits. In different series of tests, the EF from the lower leg was assessed in 70 patients with severe reflux in the great saphenous vein (GSV. EF was measured by strain gauge plethysmography, in baseline conditions and after applying graduated compression devices or the new inversely graduated or progressive compression (PC devices. The interface pressure was recorded, simultaneously with the EF, both in the gaiter area (B1 point and at the calf (C point in order to assess the compression pressure profile. EF, severely impaired in patients with GSV reflux, was increased by compression. So called PC devices (both PC elastic stocking and PC inelastic bandages were significantly more effective than graduated compression in increasing the ejection fraction. The higher the pressure on the calf the higher the EF improvement. Maintaining the same strong pressure over the calf by means of two progressive stockings and increasing the pressure only over the calf to restore a graduated compression didn’t improve the EF. To improve venous pumping function in the ambulant patient stronger compression of the calf is more effective than graduated compression. This can be explained by the higher amount of blood volume pooled in the calf veins.

    Nitric oxide (NO) and NO synthase-1 (NOS1) are involved in the stress response and in depression. We compared NOS-NO alterations in rats exposed to chronic unpredictable stress (CUS) with alterations in major depressive disorder (MDD) in humans. In the hypothalamus of male CUS rats we determined NOS activity, and in the paraventricular nucleus (PVN) we determined NOS1-immunoreactive (ir) cell densities and co-localization of NOS1 with stress-related neuropeptides corticotropin-releasing hormone (CRH), vasopressin (AVP) or oxytocin (OXT). We measured plasma NO levels and cortisol in male medicine-naïve MDD patients and plasma NO and corticosterone (CORT) in CUS rats. In the CUS rat total NOS activity in the hypothalamus (P=0.018) and NOS1-ir cell density in the PVN were both significantly decreased (P=0.018), while NOS1 staining was mainly expressed in OXT-ir neurons in this nucleus. Interestingly, plasma NO levels were significantly increased both in male CUS rats (P=0.001) and in male MDD patients (Pdepression.

    Unresponsive wakefulness syndrome (UWS) is a chronic disorder of consciousness (DOC) characterized by a lack of awareness and purposeful motor behaviors, owing to an extensive brain connectivity impairment. Nevertheless, some UWS patients may retain residual brain connectivity patterns, which may sustain a covert awareness, namely functional locked-in syndrome (fLIS). We evaluated the possibility of bringing to light such residual neural networks using a non-invasive neurostimulation protocol. To this end, we enrolled 15 healthy individuals and 26 DOC patients (minimally conscious state-MCS- and UWS), who underwent a γ-band transcranial alternating current stimulation (tACS) over the right dorsolateral prefrontal cortex. We measured the effects of tACS on power and partial-directed coherence within local and long-range cortical networks, before and after the protocol application. tACS was able to specifically modulate large-scale cortical effective connectivity and excitability in all the MCS participants and some UWS patients, who could be, therefore, considered as suffering from fLIS. Hence, tACS could be a useful approach in supporting a DOC differential diagnosis, depending on the level of preservation of the cortical large-scale effective connectivity.

    Assessing residual signs of awareness in patients suffering from chronic disorders of consciousness (DOC) is a challenging issue. DOC patient behavioral assessment is often doubtful since some individuals may retain covert traces of awareness; thus, some Unresponsive Wakefulness Syndrome (UWS) patients may be misdiagnosed. The aim of our study was to explore possible differences between the source powers within poly-modal cortices to differentiate Minimally Conscious State (MCS) from UWS. To this end, we recorded an electroencephalogram (EEG) during awake resting state and performed a Low-Resolution Brain Electromagnetic Tomography (LORETA), which is a 3D source localization method allowing the visualization of the most probable neuroanatomical generators of EEG differences. MCS and UWS patients showed significant variations concerning the frontal source power of delta-band, frontal and parietal of theta, parietal and occipital of alpha, central of beta, and parietal of gamma, in correlation with the Coma Recovery Scale-Revised (CRS-R) score. The alpha-band was the most significant LORETA data correlating with the consciousness level. In addition, we observed a significant correlation between central beta-peaks and the motor abilities and a dissociation between theta and gamma bands within parietal regions. Our findings suggest that LORETA analysis may be useful in DOC differential diagnosis since distinct neurophysiological correlates in some UWS patients could be used to assess deeper the residual cerebral activity of brain areas responsible for covert awareness.

  8. Fungal culture and sensitisation in asthma, cystic fibrosis and chronic obstructive pulmonary disorder: what does it tell us?

    2014-12-01

    Collectively asthma, chronic obstructive pulmonary disorder (COPD) and cystic fibrosis (CF) are very common, important causes of disease and ill health. Filamentous fungal colonisation of the airways can occur in all three disease groups, although the clinical relevance is unclear. Allergic bronchopulmonary aspergillosis (ABPA) is a well-recognised severe complication of airway colonisation associated primarily with Aspergillus fumigatus. Fungal colonisation may have a deleterious effect without fulfilling all the diagnostic criteria of ABPA; however, a lack of standardisation in processing respiratory samples hampers comparisons. Whilst mycology laboratory accreditation programs are common, most countries have no national standard guidelines for processing respiratory samples. Fungal recovery from sputum in CF, asthma and COPD can be around 40, 54 and 49%, respectively. Isolation of fungi from sputum has been associated with reduced lung function in asthma and CF, although no such associations have been found in COPD. It is unclear whether fungal colonisation contributes to lower lung function or is a marker of more severe lung disease and aggressive therapy. Fungal sensitisation may contribute to the persistence of active respiratory symptoms; however, the exact prevalence is unclear. Sensitisation to A. fumigatus has been associated with reduced lung function in asthma, COPD and CF. It has suggested that both skin prick tests and specific IgE measurement by the ImmunoCAP system should be used in diagnoses of allergy, due to discordance in test results; however, there is currently no widely adopted consensus as to which fungi to test for.

    The aim of this multicenter observational study conducted in France was to determine the prevalence of memory impairment in ambulatory patients aged≥70 years with chronic heart failure (HF). Two hundred ninety-one cardiologists recruited 912 ambulatory patients with HF (mean age 79.2±5.8 years) from January to November 2009. Memory was evaluated by the delayed-recall Memory Impairment Screen (MIS-D). Memory impairment was defined as MIS-D score≤6 and severe memory impairment as MIS-D score≤4. HF was diagnosed 4.4±4.8 years earlier and mean left ventricular ejection fraction was 43.6±12.0%. Memory impairment was found in 416 subjects (45.6%, 95% confidence interval 42.4 to 48.8) and severe memory impairment in 213 subjects (23.4%, 95% confidence interval 20.6 to 26.1), whereas cardiologists only suspected memory impairment in 109 patients (12%; before evaluation by MIS). Determinants of memory disorders included older age, lower education level, depression, history of stroke, renal failure, and less regular physical activity. The severity of memory impairment increased with increasing severity of HF (New York Heart Association classification; p<0.00001). In conclusion, memory impairment in older patients with HF is common. The use of a simple-to-use tool such as the MIS-D may identify patients at risk and enable implementation of management strategies to improve therapeutic compliance.

    Cerebral venous thrombosis (CVT) is a rare venous thrombotic event. We review our local experience in the management of CVT in comparison to other venous thromboembolism (VTE) with specific focus on risk factors for thrombotic recurrence. Retrospective evaluation of consecutive CVT presentations from January 2005 to June 2015, at two major tertiary hospitals in Northeast Melbourne, Australia. This population was compared to a separate audit of 1003 consecutive patients with DVT and PE. Fifty-two patients (30 female, 22 male) with a median age of 40 (18-83) years, presented with 53 episodes of CVT. Twenty-nine episodes (55 %) were associated with an underlying risk factor, with hormonal risk factors in females being most common. The median duration of anticoagulation was 6 months with 11 receiving life-long anticoagulation. Eighty-one percent had residual thrombosis on repeat imaging, which was not associated with recurrence at the same or distant site. Nine (17 %) had CVT-related haemorrhagic transformation with two resultant CVT-related deaths (RR 22.5; p = 0.04). All three VTE recurrences occured in males with unprovoked events (RR 18.2; p = 0.05) who were subsequently diagnosed with myeloproliferative neoplasm (MPN). Compared to the non-cancer VTE population, non-cancer CVT patients were younger, had similar rate of provoked events and VTE recurrence, although with significantly higher rate of MPN diagnosis (RR 9.30 (2.29-37.76); p = 0.002) CVT is a rare thrombotic disorder. All recurrences in this audit occurred in male patients with unprovoked events and subsequent diagnosis of MPN, suggesting further evaluation for MPN may be warranted in patients with unprovoked CVT.

    Background Registration of haematological malignancies presents specific challenges, and a wide range of data is required to ensure case ascertainment and proper classification of these diseases. We studied the data quality of myeloproliferative and myelodysplastic neoplasms in the Finnish Cancer Registry (FCR), comparing information with hospital discharges. Material and methods Hospital discharges (HILMO) in 2007-2013 including diagnostic codes of myeloproliferative and myelodysplastic neoplasms were extracted. Patients were individually linked to the FCR database for all haematological malignancies registered in 1953-2013. Coverage and accuracy of the FCR and agreement between registers was estimated. Results In total 5289 individuals were retrieved from two registers. Of these, 1406 were common, 1080 only found in the FCR and 2803 only in the HILMO. Coverage of myeloproliferative and myelodysplastic neoplasms in the FCR was 47.0% (95% CI 45.7-48.4%). Almost one quarter of the registrations in the FCR was based on a death certificate only. The accuracy of diagnosis was 51.4% (95% CI 49.4-53.3%), but it varied substantially by disease category. Kappa statistic for agreement between registers was excellent (0.83, 95% CI 0.80-0.85) for common cases. 7.6% of cases in the HILMO was registered as leukaemias in the FCR. Conclusions More than half of the patients found in the HILMO were entirely missing from the FCR. However, some of the diagnoses in HILMO may be preliminary and this represents the maximal number of missing cases. Cancer registers benefit from supplementary data sources, such as hospital discharges, to increase coverage and accuracy of register data on haematological malignancies.

    The myeloproliferative sarcoma virus (MPSV) infection in DBA/2 mice leads to important quantitative and qualitative changes in their hemopoiesis. These findings suggest a disturbance in the production and action of a certain hemopoietic factor similar to IL3. Here, we show that the level of the 20 alpha-hydroxysteroid dehydrogenase (20 alpha-SDH) expression, which can be induced by IL3, is dramatically increased in spleen and thymus of MPSV-infected mice. Our results suggest that quantification of 20 alpha-SDH activity can be used to indicate abnormal production of a growth factor similar to IL3 in hemopoietic system diseases.

  17. Diversity of breakpoints of variant Philadelphia chromosomes in chronic myeloid leukemia in Brazilian patients

    Directory of Open Access Journals (Sweden)

    Maria de Lourdes Lopes Ferrari Chauffaille

    2015-02-01

    Full Text Available Background: Chronic myeloid leukemia is a myeloproliferative disorder characterized by the Philadelphia chromosome or t(9;22(q34.1;q11.2, resulting in the break-point cluster regionAbelson tyrosine kinase fusion gene, which encodes a constitutively active tyrosine kinase protein. The Philadelphia chromosome is detected by karyotyping in around 90% of chronic myeloid leukemia patients, but 5-10% may have variant types. Variant Philadelphia chromosomes are characterized by the involvement of another chromosome in addition to chromosome 9 or 22. It can be a simple type of variant when one other chromosome is involved, or complex, in which two or more chromosomes take part in the translocation. Few studies have reported the incidence of variant Philadelphia chromosomes or the breakpoints involved among Brazilian chronic myeloid leukemia patients. Objective: The aim of this report is to describe the diversity of the variant Philadelphia chromosomes found and highlight some interesting breakpoint candidates for further studies. Methods: the Cytogenetics Section Database was searched for all cases with diagnoses of chronic myeloid leukemia during a 12-year period and all the variant Philadelphia chromosomes were listed. Results: Fifty (5.17% cases out of 1071 Philadelphia-positive chronic myeloid leukemia were variants. The most frequently involved chromosome was 17, followed by chromosomes: 1, 20, 6, 11, 2, 10, 12 and 15. Conclusion: Among all the breakpoints seen in this survey, six had previously been described: 11p15, 14q32, 15q11.2, 16p13.1, 17p13 and 17q21. The fact that some regions get more fre- quently involved in such rare rearrangements calls attention to possible predisposition that should be further studied. Nevertheless, the pathological implication of these variants remains unclear.

    Introduction The allostatic load model explains the additive effects of multiple biological processes that accelerate pathophysiology related to stress, particularly in the central nervous system. Stress-related mental conditions such as anxiety disorders and neuroticism (a well-known stress vulnerability factor), have been linked to disturbances of hypothalamo–pituitary–adrenal with cognitive implications. Nevertheless, there are controversial results in the literature and there is a need to determine the impact of the psychopharmacological treatment on allostatic load parameters and in cognitive functions. Gador study of Estres Modulation by Alprazolam, aims to determine the impact of medication on neurobiochemical variables related to chronic stress, metabolic syndrome, neurocognition and quality of life in patients with anxiety, allostatic load and neuroticism. Methods/analysis In this observational prospective phase IV study, highly sympthomatic patients with anxiety disorders (six or more points in the Hamilton-A scale), neuroticism (more than 18 points in the Neo five personality factor inventory (NEO-FFI) scale), an allostatic load (three positive clinical or biochemical items at Crimmins and Seeman criteria) will be included. Clinical variables of anxiety, neuroticism, allostatic load, neurobiochemical studies, neurocognition and quality of life will be determined prior and periodically (1, 2, 4, 8, and 12 weeks) after treatment (on demand of alprazolam from 0.75 mg/day to 3.0 mg/day). A sample of n=55/182 patients will be considered enough to detect variables higher than 25% (pretreatment vs post-treatment or significant correlations) with a 1-ß power of 0–80. t Test and/or non-parametric test, and Pearson's test for correlation analysis will be determined. Ethics and dissemination This study protocol was approved by an Independent Ethics Committee of FEFyM (Foundation for Pharmacological Studies and Drugs, Buenos Aires) and by regulatory

    Neck pain is the most common musculoskeletal complaint among computer office workers. There are several reports about the coexistence of neck pain and temporomandibular disorders (TMD). However, there are no studies investigating this association in the context of work involving computers. The purpose of this study was to verify the association between TMD and neck pain in computer office workers. Fifty-two female computer workers who were divided into two groups: (i) those with self-reported chronic neck pain and disability (WNP) (n = 26) and (ii) those without self-reported neck pain (WONP) (n = 26), and a control group (CG) consisting of 26 women who did not work with computers participated in this study. Clinical assessments were performed to establish a diagnosis of TMD, and craniocervical mechanical pain was assessed using manual palpation and pressure pain threshold (PPT). The results of this study showed that the WNP group had a higher percentage of participants with TMD than the WONP group (42·30% vs. 23·07%, χ(2) = 5·70, P = 0·02). PPTs in all cervical sites were significantly lower in the groups WNP and WONP compared to the CG. Regression analysis revealed TMD, neck pain and work-related factors to be good predictors of disability (R(2) = 0·93, P neck disability in computer workers is explained by the association among neck pain, TMD and unfavourable workplace conditions. Consequently, this study attempted to emphasise the importance of considering work activity for minimising neck pain-related disability.

    Full Text Available The essential oil of Syzygium aromaticum has been widely used in traditional medicine to treat a variety of diseases, including some neurological disorders. This study aims at testing, in vivo, the possible anxiolytic and antidepressant effects, of the Syzygium aromaticum essential oil against chronic manganese chloride (4.79 mg/l intoxication during the gestation and lactation period, in Wistar rat pups. Wistar rat pups were exposed to manganese via their dams’ drinking water from postnatal day (PND 1 to (PND 21. After their weaning, the rats exposed to manganese received injections of essential oil of Syzygium aromaticum (0.1 ml/kg for 18 days. The level of anxiety, depression and locomotor activity were studied. Locomotor activity (open field test, anxiety (elevated plus maze tests, and depression (forced swimming test were evaluated. The results of the present study indicate that Manganese exposure induces, on the one hand, impairments of body (p<0.001 and of brain weight (p<0.05. On the other hand, it increases level of anxiety (p<0.05, depression (p<0.001 and locomotor hyporactivity (p<0.001, when compared to control rats. Administration of essential oil of Syzygium aromaticum leads to a reduction in the level of anxiety (p<0.05, of depression (p<0.001 and corrects locomotor hyporactivity (p<0.05 in rats exposed to manganese beforehand. These results suggest that essential oil of Syzygium aromaticum can employ as a natural, protective agent against neuro-toxicity induced by manganese chloride during the gestation and lactation periods.

    Changes in serum estradiol levels are associated with mood disorders in women. However, the underlying mechanisms are not clear. Because alterations in Brain-Derived Neurotrophic Factor (BDNF) and monoamine levels in the hippocampus and amygdala have been associated with anxiety disorders, we hypothesized that chronic treatment with a low dose of estradiol would cause anxiety-like disorder by altering BDNF and monoamine levels in these regions. To test this hypothesis, female rats were sham-implanted (Controls) or implanted with pellets that release estradiol-17β (E2) for 90-days at the rate of 20 ng/day. Animals underwent behavioral tests such as the open field test and elevated plus maze test at the end of treatment. Brains from these animals were frozen, sectioned and the hippocampus, central amygdala and caudate putamen were microdissected and analyzed for monoamine levels using HPLC. BDNF protein levels in these areas were measured using ELISA and BDNF mRNA levels were analyzed using RT-PCR. In the open field test, animals chronically treated with E2 displayed anxiety-like behavior that was marked by a decrease in the number of inner zone crossings and increase in the rate of defecation compared to controls. However, no behavioral changes were observed in the elevated plus maze test. Chronic E2 treatment also decreased BDNF protein and mRNA levels in the central amygdala that was accompanied by a reduction in dopamine levels. No changes were observed in the hippocampus and caudate putamen. These results suggest that BDNF and dopamine in the central amygdala might possibly mediate chronic E2-induced behavioral alterations.

    Full Text Available Abstract Background There are several protocols designed to treat vestibular disorders that focus on habituation, substitution, adaptation, and compensation exercises. However, protocols that contemplate not only vestibular stimulation but also other components that are essential to the body balance control in older people are rare. This study aims to compare the effectiveness of two vestibular rehabilitation protocols (conventional versus multimodal on the functional capacity and body balance control of older people with chronic dizziness due to vestibular disorders. Methods/design A randomized, single-blind, controlled clinical trial with a 3 months follow-up period will be performed. The sample will be composed of older individuals with a clinical diagnosis of chronic dizziness resulting from vestibular disorders. The subjects will be evaluated at baseline, post-treatment and follow-up. Primary outcomes will be determined in accordance with the Dizziness Handicap Inventory (functional capacity and the Dynamic Gait Index (body balance. Secondary outcomes include dizziness features, functional records, body balance control tests, and psychological information. The older individuals (minimum sample n = 68 will be randomized to either the conventional or multimodal Cawthorne&Cooksey protocols. The protocols will be performed during individual 50-minute sessions, twice a week, for 2 months (a total of 16 sessions. The outcomes of both protocols will be compared according to the intention-to-treat analysis. Discussion Vestibular rehabilitation through the Cawthorne&Cooksey protocol has already proved to be effective. However, the addition of other components related to body balance control has been proposed to improve the rehabilitation of older people with chronic dizziness from vestibular disorders.

    Full Text Available Background: Posttraumatic stress disorder (PTSD tends to follow a chronic and treatment resistant course. Avoidance and numbing are symptoms associated with chronicity and impaired life quality. As D-cycloserine (DCS can facilitate extinction of conditioned fear, we aimed to investigate the efficacy and tolerability of DCS for the treatment of numbing and avoidance in chronic PTSD. Materials and Methods: This was an 11-week, double-blind, cross-over trial conducted in 2012 and 2013, in out-patient University psychiatry clinics. The studied population was selected randomly among outpatients with chronic combat-related PTSD (based on DSM-IV-TR criteria for chronic PTSD, who were males over 18 and <65 years of age (n = 319. Seventy six eligible patients were randomly assigned to two groups. Patients entered a 1-week run-in period. The groups received either an add-on treatment of DCS (50 mg daily, or placebo (4-week. After a 2-week washout, the groups received cross-over treatments (4-week. Clinical, paraclinical assessments, and clinician administered PTSD scale (CAPS were performed at baseline, and at the end of the 1 st , 5 th , and 11 th week. Side-effects were also evaluated. The overall number of avoidance and numbing symptoms, symptom frequency, and symptom intensity were measured separately. Results: Neither frequency nor number of symptoms was significantly influenced. However, DCS treatment demonstrates a significant decrease in intensity of avoidance/numbing symptoms, and improvement in function (mean [standard error] = −4.2 [1.5], P = 0.008. Side-effects were not statistically remarkable. Conclusion: D-cycloserine can help as an adjunctive treatment to alleviate numbing and avoidance in combat-related chronic PTSD.

    BCR-ABL1 negative myeloproliferative neoplasms (MPNs) are known to contain alterations of the tyrosine kinase JAK2 (located on 9p24) that result in constitutive activation of the encoded protein. JAK2 fusions are reported in acute and chronic leukemias of myeloid and lymphoid phenotypes. Here, we report an unclassified case of MPN (MPN-U) showing a t(9;22)(p24;q11), which generates a BCR-JAK2 fusion gene by fusing the BCR at intron 13 to JAK2 at intron 17 on the derivative chromosome 22. Most reported JAK2 fusions cases reveal an aggressive clinical course and long-term remissions have only been achieved after allogeneic stem cell transplantation (ASCT). To the best of our knowledge, this is the thirteenth case reported worldwide to describe a BCR-JAK2 fusion transcript in MPN-U. The present report revealed a sustained complete clinical, hematologic, and cytogenetic remission 35 months after diagnosis and ~24 months after ASCT. Regarding BCR-ABL1  negative MPN patients this case report provides strong support for a role of JAK2 activation in the oncogenesis and suggests a possible diagnostic and therapeutic target that should be investigated.

    Study Design Secondary analysis of a randomized clinical trial. Background Patient perception of the benefits gained from treatment is important, yet satisfaction with the outcome of treatment for chronic whiplash-associated disorders (WADs) has not been investigated. Objectives To investigate whether satisfaction with the outcome of treatment for chronic WAD changed over time, and whether there were group differences. Methods Two hundred sixteen people with chronic WAD (66% women; mean age, 40.4 years) participated in a 3-month program of physical therapist-led neck-specific exercises with or without a behavioral approach, or received a prescription of general physical activity. The main outcome was satisfaction with the outcome of treatment, assessed at baseline and 3, 6, and 12 months later. Additional outcomes were enablement and expectation fulfillment. Results Satisfaction improved over time in the 3 groups (odds ratio = 1.15; 95% confidence interval: 1.10, 1.20; Pphysical activity. Enablement increased after completion of the intervention in all groups (Pphysical activity (P<.01). Conclusion Exercise interventions for chronic WAD led to increased satisfaction for 12 months following treatment that was unrelated to the type of exercise intervention received.

    Brain neuroimaging has been widely used to investigate the bran signature of chronic orofacial pain, including trigeminal neuropathic pain (TNP) and pain related to temporomandibular joint disorders (TMD). We here systematically reviewed the neuroimaging literature regarding the functional and structural changes in the brain of TNP and TMD pain patients, using a computerized search of journal articles via PubMed. Ten TNP studies and 14 TMD studies were reviewed. Study quality and risk of bias were assessed based on the criteria of patient selection, the history of medication, the use of standardized pain/psychological assessments, and the model and statistics of imaging analyses. Qualitative meta-analysis was performed by examining the brain regions which showed significant changes in either brain functions (including the blood-oxygen-level dependent signal, cerebral blood flow and the magnetic resonance spectroscopy signal) or brain structure (including gray matter and white matter anatomy). We hypothesized that the neuroimaging findings would display a common pattern as well as distinct patterns of brain signature in the disorders. This major hypothesis was supported by the following findings: (1) TNP and TMD patients showed consistent functional/structural changes in the thalamus and the primary somatosensory cortex, indicating the thalamocortical pathway as the major site of plasticity. (2) The TNP patients showed more alterations at the thalamocortical pathway, and the two disorders showed distinct patterns of thalamic and insular connectivity. Additionally, functional and structural changes were frequently reported in the prefrontal cortex and the basal ganglia, suggesting the role of cognitive modulation and reward processing in chronic orofacial pain. The findings highlight the potential for brain neuroimaging as an investigating tool for understanding chronic orofacial pain.

    Full Text Available We previously found that gender influenced the JAK2 V617F allele burden, but it is unknown whether this gender difference in molecular epidemiology influences complications in the myeloproliferative neoplasms (MPNs. Historically, vascular complications represented the most common cause of mortality in polycythemia vera and essential thrombocytosis and contributed to morbidity in primary myelofibrosis. To determine the influence of gender on vascular complications, we retrospectively analyzed associations between gender and vascular complications. Despite their younger age, less prevalent dyslipidemia or smoking history, lower white blood counts, and lower JAK2 V617F allele burden, women had higher rates of abdominal venous thrombosis and comparable rates of all vascular complications. Vascular risk is currently not easily stratified by MPN-disease burden or traditional risk factors. Our analysis contributes to growing literature emphasizing gender differences in the MPN and further supports the important impact of individual and host variation on MPN clinical manifestations, and especially vascular risk.

    Tic severity is composed of several dimensions. Tic frequency and intensity are two such dimensions, but little empirical data exist regarding their relative contributions to functional impairment in those with chronic tic disorders (CTD). The present study examined the relative contributions of these dimensions in predicting tic-related impairment across several psychosocial domains. Using data collected from parents of youth with CTD, multivariate regression analyses revealed that both tic frequency and intensity predicted tic-related impairment in several areas; including family and peer relationships, school interference, and social endeavors, even when controlling for the presence of comorbid anxiety symptoms and Attention Deficit Hyperactivity Disorder diagnostic status. Results showed that tic intensity predicted more variance across more domains than tic frequency.

    Full Text Available Chromosomal translocations are driver mutations of human cancers, particularly leukemias. They define disease subtypes and are used as prognostic markers, for minimal residual disease monitoring and therapeutic targets. Due to their low incidence, several translocations and their biological consequences remain poorly characterized. To address this, we engineered mouse strains that conditionally express E2A-HLF, a fusion oncogene from the translocation t(17;19 associated with 1% of pediatric B-cell precursor ALL. Conditional oncogene activation and expression were directed to the B-cell compartment by the Cre driver promoters CD19 or Mb1 (Igα, CD79a, or to the hematopoietic stem cell compartment by the Mx1 promoter. E2A-HLF expression in B-cell progenitors induced hyposplenia and lymphopenia, whereas expression in hematopoietic stem/progenitor cells was embryonic lethal. Increased cell death was detected in E2A-HLF expressing cells, suggesting the need for cooperating genetic events that suppress cell death for B-cell oncogenic transformation. E2A-HLF/Mb1.Cre aged mice developed a fatal myeloproliferative-like disorder with low frequency characterized by leukocytosis, anemia, hepatosplenomegaly and organ-infiltration by mature myelocytes. In conclusion, we have developed conditional E2A-HLF knock-in mice, which provide an experimental platform to study cooperating genetic events and further elucidate translational biology in cross-species comparative studies.

    Full Text Available BACKGROUND: Ph-negative myeloproliferative neoplasms (MPNs are clonal disorders that include primary myelofibrosis (PMF, polycythemia vera (PV and essential thrombocythemia (ET. Although the pathogenesis of MPNs is still incompletely understood, an involvement of the megakaryocyte lineage is a distinctive feature. METHODOLOGY/PRINCIPAL FINDINGS: We analyzed the in vitro megakaryocyte differentiation and proplatelet formation in 30 PMF, 8 ET, 8 PV patients, and 17 healthy controls (CTRL. Megakaryocytes were differentiated from peripheral blood CD34(+ or CD45(+ cells in the presence of thrombopoietin. Megakaryocyte output was higher in MPN patients than in CTRL with no correlation with the JAK2 V617F mutation. PMF-derived megakaryocytes displayed nuclei with a bulbous appearance, were smaller than ET- or PV-derived megakaryocytes and formed proplatelets that presented several structural alterations. In contrast, ET- and PV-derived megakaryocytes produced more proplatelets with a striking increase in bifurcations and tips compared to both control and PMF. Proplatelets formation was correlated with platelet counts in patient peripheral blood. Patients with pre-fibrotic PMF had a pattern of megakaryocyte proliferation and proplatelet formation that was similar to that of fibrotic PMF and different from that of ET. CONCLUSIONS/SIGNIFICANCE: In conclusion, MPNs are associated with high megakaryocyte proliferative potential. Profound differences in megakaryocyte morphology and proplatelet formation distinguish PMF, both fibrotic and prefibrotic, from ET and PV.

    2010-01-01

    Full Text Available Whiplash-associated disorder (WAD represents a significant public health problem, resulting in substantial social and economic costs throughout the industrialized world. While many treatments have been advocated for patients with WAD, scientific support regarding their effectiveness is often lacking. A systematic review was conducted to evaluate the strength of evidence associated with various WAD therapies. Multiple databases (including Web of Science, EMBASE and PubMed were searched to identify all studies published from January 1980 through March 2009 that evaluated the effectiveness of any well-defined treatment for acute (less than two weeks, subacute (two to 12 weeks or chronic (more than 12 weeks WAD. The present article, the fifth in a five-part series, evaluates the evidence for surgical and injection-based interventions initiated during the chronic phase of WAD. Twenty-five studies were identified that met the inclusion criteria, six of which were randomized controlled trials with ‘good’ overall methodological quality (median Physiotherapy Evidence Database score of 7.5. For the treatment of chronic WAD, there was moderate evidence supporting radiofrequency neurotomy as an effective treatment for whiplash-related pain, although relief is not permanent. Sterile water injections have been demonstrated to be superior to saline injections; however, it is not clear whether this treatment is actually beneficial. There was evidence supporting a wide range of other interventions (eg, carpal tunnel decompression with each of these evaluated by a single nonrandomized controlled trial. There is contradictory evidence regarding the effectiveness of botulinum toxin injections, and cervical discectomy and fusion. The evidence is not yet strong enough to establish the effectiveness of any of these treatments; of all the invasive interventions for chronic WAD, radiofrequency neurotomy appears to be supported by the strongest evidence.

    Hyperphosphatemia is a serious complication which has been linked with an increased risk of cardiovascular mortality in patients with chronic kidney disease. Lanthanum carbonate is a novel non-calcium, non-aluminum phosphate-binding agent, and has approved for clinical use in patients on hemodialysis in Japan on March in 2009. Compared to calcium carbonate and sevelamer hydrochloride, lanthanum carbonate is a powerful phosphate binder. There is no evidence of bone toxicity and neurotoxicity of lanthanum carbonate previously reported for aluminium hydroxide. However, further studies are needed to address the longer term toxic effect on bone and other organs.

    2014-08-01

    Biopsychosocial conceptualizations of eating disorders (EDs) suggest the combination of an individual's emotional vulnerability and invalidating environment increases the likelihood of developing pervasive emotion dysregulation, and subsequent use of ED behaviors to regulate emotion (Haynos & Fruzetti, 2011; Safer, Telch, & Chen, 2009). The current study aimed to provide initial support for this model in adolescent EDs, through examining the interaction between an adolescent's emotional vulnerability, indexed by attentional biases for emotions, and an invalidating family environment. Specifically, we examined the ability of this interaction to discriminate youth with EDs from a comparison group of youth with chronic pain diagnoses, who were used to control for the presence of non-specific effects of having any illness. Fifty adolescent girls (25 with EDs and 25 with chronic pain) completed an emotional dot-probe task assessing attentional biases for emotional faces, and parents completed the Emotions as a Child Scale (Magai, 1996; Klimes-Dougan et al., 2007) to assess response to teen emotion. Results showed that teen angry attentional bias moderated the relationship between parental response to sadness and teen ED status: for teens with high attention bias towards angry faces, maladaptive parental response to sadness predicted increased odds of ED status versus chronic pain status.

    Juvenile myelomonocytic leukemia is a rare myeloproliferative neoplasm characterized by hyperactive RAS signaling. Neurofibromin1 (encoded by the NF1 gene) is a negative regulator of RAS activation. Patients with neurofibromatosis type 1 harbor loss-of-function mutations in NF1 and have a 200- to 500-fold increased risk of juvenile myelomonocytic leukemia. Leukemia cells from patients with juvenile myelomonocytic leukemia display hypersensitivity to certain cytokines, such as granulocyte-macrophage colony-stimulating factor. The granulocyte-macrophage colony-stimulating factor receptor utilizes pre-associated JAK2 to initiate signals after ligand binding. JAK2 subsequently activates STAT5, among other downstream effectors. Although STAT5 is gaining recognition as an important mediator of growth factor signaling in myeloid leukemias, the contribution of STAT5 to the development of hyperactive RAS-initiated myeloproliferative disease has not been well described. In this study, we investigated the consequence of STAT5 attenuation via genetic and pharmacological approaches in Nf1-deficient murine models of juvenile myelomonocytic leukemia. We found that homozygous Stat5 deficiency extended the lifespan of Nf1-deficient mice and eliminated the development of myeloproliferative neoplasm associated with Nf1 gene loss. Likewise, we found that JAK inhibition with ruxolitinib attenuated myeloproliferative neoplasm in Nf1-deficient mice. Finally, we found that primary cells from a patient with KRAS-mutant juvenile myelomonocytic leukemia displayed reduced colony formation in response to JAK2 inhibition. Our findings establish a central role for STAT5 activation in the pathogenesis of juvenile myelomonocytic leukemia and suggest that targeting this pathway may be of clinical utility in these patients.

    Interferon (IFN) therapy for chronic hepatitis C is sometimes associated with cardiac complications. In the present study, we performed myocardial imaging with {sup 123}I-labeled {beta}-methyl-p-iodophenylpentadecanoic acid ({sup 123}I-BMIPP) in order to evaluate myocardial disorders caused by IFN. We studied 40 healthy subjects (H group) and 25 patients with chronic hepatitis C who had been treated with IFN (IFN group). A Holter electrocardiogram (ECG) was performed and the autonomic nervous function was assessed by analyzing the spectral variability and 1/f fluctuation of heart rate. Myocardial planner imaging with {sup 123}I-BMIPP was performed to obtain the time activity curve for 20 min immediately after administration of {sup 123}I-BMIPP (dynamic study). Early and delayed myocardial single photon emission computed tomography (SPECT) images were expressed as Bull's eyes and the myocardium was divided into four segments to calculate the washout rate for each segment on early and late SPECT images (early and late SPECT study). No significant differences in autonomic nervous function were observed between the two groups in heart rate variability. In a dynamic study, the reduction rate from the time activity curve was significantly higher in the IFN group compared with the H group (reduction rate, IFN group, 5.3{+-}3.7% vs H group, 1.2{+-}3.3%; P<0.05). In the early and delayed myocardial SPECT study, the washout rate for the IFN group was significantly increased in all myocardial areas compared to that in the H group. However, the metabolic disorder of fatty acids caused by IFN was reversed on the second {sup 123}I-BMIPP myocardial scintigraphy examination several months after IFN therapy. These results indicate that metabolic disorders of fatty acids caused by IFN therapy can be detected before abnormalities are observed by Holter-ECG or echocardiography. (author)

    The clinical practice guidelines for the prevention, diagnosis, evaluation and treatment of chronic kidney disease mineral and bone disorders (CKD-BMD) in adults, of the Latin American Society of Nephrology and Hypertension (SLANH) comprise a set of recommendations developed to support the doctor in the management of these abnormalities in adult patients with stages 3-5 kidney disease. This excludes changes associated with renal transplantation. The topics covered in the guidelines are divided into four chapters: 1) Evaluation of biochemical changes, 2) Evaluation of bone changes, 3) Evaluation of vascular calcifications, and 4) Treatment of CKD-MBD. The guidelines are based on the recommendations proposed and published by the Kidney Disease: Improving Global Outcomes (KDIGO) for the prevention, diagnosis, evaluation and treatment of CKD-MBD (KDIGO Clinical practice guidelines for the diagnosis, evaluation, prevention and treatment of Chronic Kidney Disease Mineral and Bone Disorder [CKD-MBD]), adapted to the conditions of patients, institutions and resources available in Latin America, with the support of KDIGO. In some cases, the guidelines correspond to management recommendations directly defined by the working group for their implementation in our region, based on the evidence available in the literature. Each chapter contains guidelines and their rationale, supported by numerous updated references. Unfortunately, there are few controlled studies with statistically sufficient weight in Latin America to support specific recommendations for the region, and as such, most of the references used correspond to studies carried out in other regions. This highlights the need to plan research studies designed to establish the current status of mineral and bone metabolism disorders in Latin America as well as defining the best treatment options for our population.

    Recently, many investigators have reported that treatment with vitamin D improves outcomes of patients with chronic kidney disease. Though the detailed mechanisms have remained unclear, it has been speculated that such a treatment may prevent progression of chronic kidney disease and cardiovascular disease. It has been reported that Vitamin D may attenuate renal injury and ameliorate renal function and proteinuria. In addition, several studies have shown that vitamin D may prevent progression of atherosclerosis, vascular calcification and left ventricular hypertrophy. The emerging experimental and clinical evidence has suggested that vitamin D may protect kidney and cardiovascular system.

    Full Text Available We deeply appreciate your publishing of our work - “Chronic metabolic acidosis destroys pancreas” in JOP (2014 [1]. We feel that our work can give the food for thought to many young researchers and health practitioners. A short review of our work may generate various questions and ideas for further investigations. In our work, we have focused on negative affects of the chronic metabolic acidosis on pancreatic function including: • Premature activation of the proteases within the pancreas • Diminishing the antimicrobial activity of the pancreatic juice • Suppressing of the flushing out zymogens from the pancreas • Precipitation of the aggressive bile acids • Calcification Authors believe that further research may provide more details of how the acidification destroys the pancreas and causes chronic pancreatitis. We would like to share some of our thoughts on this subject as follows: Descriptions of symptoms of chronic pancreatitis such as pain, malabsorption syndrome, steatorrhea, and weight loss are found in almost all medical books, textbooks, and articles. The medical literature refers to these conditions as “pancreatic insufficiency”. It is known that these symptoms occur when only 10 % of the exocrine pancreatic function is left intact. This is not an “insufficiency.” It is a pancreatic “failure” when the therapeutic opportunities are very limited.

Ruxolitinib, a JAK1/JAK2 tyrosine kinase inhibitor, is now widely used for first- and second-line therapy in persons with MPN-MF, especially those with disease-related splenomegaly, intermediate- or high-risk disease, and constitutional symptoms. The goal of this work is to critically analyze data supporting use of ruxolitinib in the clinical settings approved by the US Food and Drug Administration (FDA and European Medicines Agency (EMA. We systematically reviewed the literature and analyzed the risk of biases in the two randomized studies (COMFORT I and COMFORT II on which FDA and EMA approval was based. Our strategy was to apply the Grading of Recommendation, Assessment, Development and Evaluation (GRADE approach by evaluating five dimensions of evidence: (1 overall risk of bias, (2 imprecision, (3 inconsistency, (4 indirectness, and (5 publication bias. Based on these criteria, we downgraded the evidence from the COMFORT I and COMFORT II trials for performance, attrition, and publication bias. In the disease-associated splenomegaly sphere, we upgraded the quality of evidence because of large effect size but downgraded it because of comparator choice and outcome indirectness (quality of evidence, low. In the sphere of treating persons with intermediate- or high-risk disease, we downgraded the evidence because of imprecision in effect size measurement and population indirectness. In the sphere of disease-associated symptoms, we upgraded the evidence because of the large effect size, but downgraded it

    Full Text Available Abstract Background In Low and Middle Income Countries, mental health services are often poorly developed due to the lack of resources and trained personnel. In order to overcome these challenges, new ways of care have been suggested such as a focus on community-based services. In Somalia, the consumption of the natural stimulant khat is highly prevalent, aggravating mental illness. At the same time, mental health care is largely unavailable to the vast majority of the population. In a pilot project, we tested possibilities for effective measures in community-based out-patient mental health care. Methods Thirty-five male patients with chronic psychotic disorders and their carers were involved in a 10-months follow-up study. All of them abused khat. Seventeen outpatients experiencing acute psychotic episodes were recruited from the community and received an intensive six week home-based treatment package. Additionally eighteen patients with chronic psychotic disorders in remission were recruited either following hospital discharge or from the community. In a second phase of the study, both groups received community-based relapse prevention that differed in the degree of the family’s responsibility for the treatment. The treatment package was comprised of psycho-education, low-dose neuroleptic treatment, monthly home visits and counseling. The Brief Psychiatric Rating Scale (BPRS was applied three times. Additionally, we assessed functioning, khat use and other outcomes. Results Of the 35 patients enrolled in the study, 33 participated in the 10-month follow-up. Outpatients improved significantly in the first six weeks of treatment and did not differ from remitted patients at the start of the second treatment phase. In the preventive treatment phase, we find heterogeneous outcomes that diverge between symptom and functioning domains. With the exception of depressive symptoms, symptoms in all patients tended to worsen. The outpatient group had

The tyrosine kinase inhibitor (TKI imatinib was the first targeted therapy licensed for patients with chronic-phase CML, and its introduction was associated with substantial improvements in response and survival compared with previous therapies. Clinical trial data are now available for the second-generation TKIs (nilotinib, dasatinib, and bosutinib in the first-, second-, and third-line settings. A qualitative systematic review was conducted to qualitatively compare the clinical effectiveness, safety, and effect on quality of life of TKIs for the management of chronic-, accelerated-, or blast-phase CML patients.Methods: Included studies were identified through a search of electronic databases in September 2011, relevant conference proceedings and the grey literature.Results: In the first-line setting, the long-term efficacy (up to 8 years of imatinib has been confirmed in a single randomized controlled trial (International Randomized Study of Interferon [IRIS]. All second-generation TKIs reported lower rates of transformation, and comparable or superior complete cytogenetic response (CCyR, major molecular response (MMR, and complete molecular response rates compared with imatinib by 2-year follow-up. Each of the second-generation TKIs was associated with a distinct adverse-event profile. Bosutinib was the only second-generation TKI to report quality-of-life data (no significant difference compared with imatinib treatment. Data in the second- and third-line setting confirmed the efficacy of the second-generation TKIs in either imatinib-resistant or -intolerant patients, as measured by CCyR and MMR rates.Conclusion: Data from first-line randomized controlled trials reporting up to 2-year follow-up indicate superior response

  14. CLIPPERS: chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids. Review of an increasingly recognized entity within the spectrum of inflammatory central nervous system disorders.

    Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is a recently defined inflammatory central nervous system (CNS) disorder, prominently involving the brainstem and in particular the pons. The condition features a combination of clinical symptoms essentially referable to brainstem pathology and a characteristic magnetic resonance imaging (MRI) appearance with punctate and curvilinear gadolinium enhancement 'peppering' the pons. The radiological distribution is focused in the pons and adjacent rhombencephalic structures such as the cerebellar peduncles, cerebellum, medulla and the midbrain. While the lesion burden with a perivascular pattern is typically most dense in these pontine and peripontine regions, enhancing lesions may additionally extend into the spinal cord and supratentorial structures such as the thalamus, basal ganglia, capsula interna, corpus callosum and the cerebral white matter. Another core feature is clinical and radiological responsiveness to glucocorticosteroid (GCS)-based immunosuppression. As withdrawal of GCS treatment results commonly in disease exacerbation, long-term immunosuppressive therapy appears to be mandatory for sustained improvement. Diagnosis of CLIPPERS is challenging, and requires careful exclusion of alternative diagnoses. A specific serum or cerebrospinal fluid (CSF) biomarker for the disorder is currently not known. Pathogenesis of CLIPPERS remains poorly understood, and the nosological position of CLIPPERS has still to be established. Whether CLIPPERS represents an independent, actual new disorder or a syndrome that includes aetiologically heterogeneous diseases and/or their prestages remains a debated and not finally clarified issue. Clinicians and radiologists should be aware of this condition and its differential diagnoses, given that CLIPPERS constitutes a treatable condition and that patients may benefit from an early introduction of GCS ensued by long

    Recent reports of several bone-derived substances, some of which have hormonal properties, have shed new light on the bone-cardiovascular axis. Deranged concentrations of humoral factors are not only epidemiologically connected to cardiovascular morbidity and mortality, but can also be causally implicated, especially in chronic kidney disease. FGF23 rises exponentially with advancing chronic kidney disease, seems to reach maladaptive concentrations, and then induces left ventricular hypertrophy, and is possibly implicated in the process of vessel calcification. Sclerostin and DKK1, both secreted mainly by osteocytes, are important Wnt inhibitors and as such can interfere with systems for biological signalling that operate in the vessel wall. Osteocalcin, produced by osteoblasts or released from mineralised bone, interferes with insulin concentrations and sensitivity, and its metabolism is disturbed in kidney disease. These bone-derived humoral factors might place the bone at the centre of cardiovascular disease associated with chronic kidney disease. Most importantly, factors that dictate the regulation of these substances in bone and subsequent secretion into the circulation have not been researched, and could provide entirely new avenues for therapeutic intervention.

    The Pain and Interoception Imaging Network (PAIN) repository (painrepository.org) is a newly created NIH (NIDA/NCCAM) funded neuroimaging data repository that aims to accelerate scientific discovery regarding brain mechanisms in pain and to provide more rapid benefits to pain patients through the harmonization of efforts and data sharing. The PAIN Repository consists of two components, an Archived Repository and a Standardized Repository. Similar to other 'open' imaging repositories, neuroimaging researchers can deposit any dataset of chronic pain patients and healthy controls into the Archived Repository. Scans in the Archived Repository can be very diverse in terms of scanning procedures and clinical metadata, complicating the merging of datasets for analyses. The Standardized Repository overcomes these limitations through the use of standardized scanning protocols along with a standardized set of clinical metadata, allowing an unprecedented ability to perform pooled analyses. The Archived Repository currently includes 741 scans and is rapidly growing. The Standardized Repository currently includes 433 scans. Pain conditions currently represented in the PAIN repository include: irritable bowel syndrome, vulvodynia, migraine, chronic back pain, and inflammatory bowel disease. Both the PAIN Archived and Standardized Repositories promise to be important resources in the field of chronic pain research. The enhanced ability of the Standardized Repository to combine imaging, clinical and other biological datasets from multiple sites in particular make it a unique resource for significant scientific discoveries.

  1. Novel Treatment of Chronic Bladder Pain Syndrome and Other Pelvic Pain Disorders by OnabotulinumtoxinA Injection

    2015-06-01

    Full Text Available Chronic pelvic pain (CPP is defined as pain in the pelvic organs and related structures of at least 6 months’ duration. The pathophysiology of CPP is uncertain, and its treatment presents challenges. Botulinum toxin A (BoNT-A, known for its antinociceptive, anti-inflammatory, and muscle relaxant activity, has been used recently to treat refractory CPP with promising results. In patients with interstitial cystitis/bladder pain syndrome, most studies suggest intravesical BoNT-A injection reduces bladder pain and increases bladder capacity. Repeated BoNT-A injection is also effective and reduces inflammation in the bladder. Intraprostatic BoNT-A injection could significantly improve prostate pain and urinary frequency in the patients with chronic prostatitis/chronic pelvic pain syndrome. Animal studies also suggest BoNT-A injection in the prostate decreases inflammation in the prostate. Patients with CPP due to pelvic muscle pain and spasm also benefit from localized BoNT-A injections. BoNT-A injection in the pelvic floor muscle improves dyspareunia and decreases pelvic floor pressure. Preliminary studies show intravesical BoNT-A injection is useful in inflammatory bladder diseases such as chemical cystitis, radiation cystitis, and ketamine related cystitis. Dysuria is the most common adverse effect after BoNT-A injection. Very few patients develop acute urinary retention after treatment.

    Abstract Background: Sleep disturbance is a common symptom in CC patients, and it is positively related to greater somatic and psychiatric symptoms. Methods: The participants were 126 adult outpatients with CC. The measures were: constipation—Constipation Scoring System (CSS) and Patient Assessment of Constipation-Symptoms (PAC-SYM); sleep—Pittsburgh Sleep Quality Index (PSQI); anxiety—General Anxiety Disorder-7 (GAD-7); depression—Patient Health Questionnaire-9 (PHQ-9); and QOL—Patient Assessment of Constipation Quality of Life (PAC-QOL) and SF-36. Patients were divided into sleep-disorder and normal-sleep groups by their PSQI scores. Results: The sleep-disorder group had significantly higher rates of incomplete defecation and blockage and higher CSS scores, PAC-SYM total scores, and PAC-SYM rectal-item scores than the normal-sleep group. GAD-7 and PHQ-9 scores were significantly higher in patients with poor sleep. Furthermore, sleep disorders, depression, and anxiety were all positively correlated with constipation severity. “Worry/anxiety” score of PAC-QOL scale was significantly higher and scores for seven SF-36 subscales were significantly lower in patients with poor sleep. In addition, correlation analyses showed significant negative relations between QOL and constipation, sleep disturbance, anxiety as well as depression. However, multiple regression revealed that PAC-QOL was positively associated with severe constipation and SF-36 was negatively associated with anxiety and depression. But sleep disturbance was not the independent risk factor for QOL of CC patients. Conclusion: Sleep disorders may worsen the physical- and mental health of CC patients. Sleep disturbance may lower CC patients’ QOL indirectly through the combined effects of anxiety, depression, and constipation. PMID:28207519

    This pilot study was designed to examine the effects of mixed Light Touch Manual Therapies (LTMT) on headache, anxiety and other symptoms suffered by active duty United States service members experiencing chronic Post-Traumatic Stress Disorder (PTSD). Ten service members diagnosed with PTSD and having a self-reported injury to the head acquired at least two years prior, were provided with two hour-long sessions of mixed LTMT given a week apart. Data to assess the immediate and durable effects were gathered before and after the LTMT sessions. Results indicate that headache, anxiety, and pain interference were significantly reduced during the course of the pilot study. This suggests that mixed LTMT may be helpful in reducing some of the symptoms of PTSD and injury to the head. Further studies will be needed to determine if LTMT is an effective non-pharmacological treatment for headache, anxiety or other problems associated with PTSD or injury to the head.

    An 84-year-old woman was referred to our hospital presenting anemia. Her hemoglobin level was 5.8 g/dL, and white blood cell count was 9400/μL, consisting of 82% lymphocytes. Given the lymphocyte phenotype (CD2+, CD3-, CD16+, and CD56-) and negative whole blood EBV viral load, we made a diagnosis of chronic lymphoproliferative disorder of NK cells (CLPD-NK). We suspected hemolytic anemia because of the high levels of reticulocytes in the peripheral blood and the low haptoglobin value. Although the direct Coombs test was negative and there was no cold agglutination, we examined her red-blood-cell-bound IgG (RBC-IgG), which was elevated. She was diagnosed as having as Coombs-negative autoimmune hemolytic anemia (AIHA). We report the effectiveness of oral cyclophosphamide for Coombs-negative autoimmune hemolytic anemia in CLPD-NK.

    A quarter of patients with essential thrombocythemia or primary myelofibrosis carry a driver mutation of CALR, the calreticulin gene. A 52-bp deletion (type 1) and a 5-bp insertion (type 2 mutation) are the most frequent variants. These indels might differentially impair the calcium binding activity of mutant calreticulin. We studied the relationship between mutation subtype and biological/clinical features of the disease. Thirty-two different types of CALR variants were identified in 311 patients. Based on their predicted effect on calreticulin C-terminal, mutations were classified as: (i) type 1-like (65%); (ii) type 2-like (32%); and (iii) other types (3%). Corresponding CALR mutants had significantly different estimated isoelectric points. Patients with type 1 mutation, but not those with type 2, showed abnormal cytosolic calcium signals in cultured megakaryocytes. Type 1-like mutations were mainly associated with a myelofibrosis phenotype and a significantly higher risk of myelofibrotic transformation in essential thrombocythemia. Type 2-like CALR mutations were preferentially associated with an essential thrombocythemia phenotype, low risk of thrombosis despite very-high platelet counts and indolent clinical course. Thus, mutation subtype contributes to determining clinical phenotype and outcomes in CALR-mutant myeloproliferative neoplasms. CALR variants that markedly impair the calcium binding activity of mutant calreticulin are mainly associated with a myelofibrosis phenotype. PMID:26449662

    At present, very few data are available on deferasirox (DFX) in the treatment of patients with Philadelphia-negative myeloproliferative neoplasms in fibrotic phase (FP-MPN) and transfusion dependence. To address this issue, a retrospective analysis of 28 patients (22 male and 6 female) with FP-MPN and iron overload secondary to transfusion dependence was performed, based on patients enrolled in the database of our regional cooperative group who received treatment with DFX. DFX was started after a median interval from diagnosis of 12.8 months (IR 7.1-43.1) with median ferritin values of 1415 ng/mL (IR 1168-1768). Extra-hematological toxicity was reported in 16 of 28 patients (57.1%), but only two patients discontinued treatment due to toxicity. Among 26 patients evaluable for response (≥6 months of treatment), after a median treatment period of 15.4 months (IR 8.1-22.3), 11 patients (42.3%) achieved a stable and consistent reduction in ferritin levels 3 months) rise of Hb levels >1.5 g/dL, with disappearance of transfusion dependence in four cases. Treatment with DFX is feasible and effective in FP-MPN with iron overload. Moreover, in this setting, an erythroid response can occur in a significant proportion of patients.

    Myeloproliferative neoplasms (MPNs), with an expected increment in number, impose substantial economic and social burdens. To this end, we conducted a nationwide population-based descriptive epidemiology study. We also investigated medical cost associated with MPNs. Prevalence was the highest for essential thrombocythemia (ET) (range 4.1-9.0 per 100,000), followed by polycythemia vera (PV) (range 2.8-5.4 per 100,000) and primary myelofibrosis (PMF) (range 0.5-0.9 per 100,000). ET incurred the highest cumulative total cost at US$35 million and the most frequent hospital visits, while PMF incurred the highest average cost per person at US$5000. The mean hemoglobin level was 16.9 ± 2.2 g/dL for PV males and 15.5 ± 2.7 g/dL for PV females. Further analyses on hemoglobin levels showed the true positive rate of PV from the significantly elevated hemoglobin group (defined as >18.5 g/dL for men and >16.5 g/dL for women) was 3.01% and that of MPNs was 3.1%. Here, we provide the biggest population-based report on MPN epidemiology that can readily be used as a representative Asian data.

CALR mutations were described recently in Janus kinase 2 gene (JAK2-negative or MPLnegative primary myelofibrosis (PMF and essential thrombocythemia (ET patients. CALR trails JAK2 as the second most mutated gene in myeloproliferative neoplasms (MPNs. However, little is known about CALR mutation in Chinese patients with leukemia. In the present study, a cohort of 305 Chinese patients with hematopoietic neoplasms was screened for CALR mutations, with the aim of uncovering the frequency of CALR mutations in leukemia and MPNs. Materials and Methods: Polymerase chain reaction and direct sequencing were performed to analyze mutations of CALR in 305 patients with hematopoietic malignancies, including 135 acute myeloid leukemia patients, 57 acute lymphoblastic leukemia patients, and 113 MPN patients. Results: CALR mutations were found in 10.6% (12 of 113 of samples from patients with MPNs. CALR mutations were determined in 11.3% (6 of 53, 21.7% (5 of 23, and 9.1% (1/11 of patients with ET, PMF, and unclassifiable MPN, respectively. Conclusion: We showed that MPN patients carrying CALR mutations presented with higher platelet counts and lower hemoglobin levels compared to those with mutated JAK2. However, all of the leukemia patients had negative results for CALR mutations.

    Whiplash Associated Disorders (WAD) refers to the multifaceted and chronic burden that is common after a whiplash injury. Tools to assist in the diagnosis of WAD and an increased understanding of neck muscle behaviour are needed. We examined the multilayer dorsal neck muscle behaviour in nine women with chronic WAD versus healthy controls during the entire sequence of a dynamic low-loaded neck extension exercise, which was recorded using real-time ultrasound movies with high frame rates. Principal component analysis and orthogonal partial least squares were used to analyse mechanical muscle strain (deformation in elongation and shortening). The WAD group showed more shortening during the neck extension phase in the trapezius muscle and during both the neck extension and the return to neutral phase in the multifidus muscle. For the first time, a novel non-invasive method is presented that is capable of detecting altered dorsal muscle strain in women with WAD during an entire exercise sequence. This method may be a breakthrough for the future diagnosis and treatment of WAD.

    Chronic obstructive pulmonary disease ( COPD) is one of the most common diseases of the respiratory, with a gradual development. Avoiding inhaling harmful gas and medication do not prevent decline in lung function because of persistence of chronic in-flammation, which is associated with innate immunity disorders and frequent infections in the lungs of patients. Effective treatment strategies should be focused on restoring the innate immune system function.%慢性阻塞性肺疾病为呼吸科常见疾病,病情呈现逐渐性进展,药物治疗及避免有害气体接触并不能阻止肺功能下降,提示患者肺内慢性炎症持续存在,其原因与固有免疫紊乱、病原体反复感染有关。有效的治疗策略应注重恢复固有免疫系统功能。

    This study investigated the relationship between chronic head, face and neck pain, and the level of depression in Croatian war veterans with post-traumatic stress disorder (PTSD). The presence of self-reported pain, pain on digital palpation, and pain severity in masticatory and neck muscles, temporomandibular joints and sinuses, as well as the level of depression were assessed in a group of war veterans with PTSD (n=52). Control groups consisted of war veterans without PTSD (n=50) and healthy men that were not engaged in war actions and were free from PTSD (n=50). The number of self-reported pain and number of painful sites were correlated with the level of depression. More self-reported pain and painful sites were recorded in the group of war veterans with PTSD as compared with either war veterans without PTSD or healthy men. Furthermore, PTSD patients mostly suffered from severe depression. There was a statistically significant positive correlation between all investigated pain parameters and level of depression. As the most important finding, the present study demonstrated chronic head, face and neck pain to be related to depression in PTSD patients.

    We present the preliminary results of a retrospective study on 56 patients who underwent the Kapandji-Sauvé procedure for chronic disorders of the distal radioulnar joint (DRUJ). Outcome was assessed with special regard to the long-term results. The average follow-up was 5.9 years (1 to 12 years). 15 of the 56 operations were performed before 1996. Most procedures were performed because of secondary arthrosis or chronic dislocation of the DRUJ after distal radius fracture. Patients were assessed for pain, range of motion of wrist and forearm and radiological features. The DASH score and Mayo wrist score were used. Pain was improved in 94 % of the patients, but only 53 % were free of symptoms during heavy manual labour concerning the operated site. In four cases symptoms of ulnar impingement were found. Improvement in range of motion of wrist and forearm was significant. The post-operative DASH score was 22.6 +/- 20.0 and the Mayo wrist score was 79.5 +/- 14.6. One non-union of the DRUJ with consecutive fracture of the fixation screw and an algodystrophy in another case were found as postoperative complications. The only long-term complication consisted of a beginning humeroradial arthrosis ten years after the operation. The results demonstrate high patient satisfaction and reliable improvement in range of motion. Our results confirm the Kapandji-Sauvé procedure to be a reliable salvage procedure for arthrosis or chronic dislocation of the DRUJ even after long-term follow up.

    Full Text Available Abstract Background Few studies have investigated the independent effects of occupational exposures and smoking on chronic bronchitis and airflow obstruction. We assessed the association between lifetime occupational exposures and airflow obstruction in a cross-sectional survey in an urban-industrial area of Catalonia, Spain. Methods We interviewed 576 subjects of both sexes aged 20–70 years (response rate 80% randomly selected from census rolls, using the ATS questionnaire. Forced spirometry was performed by 497 subjects according to ATS normative. Results Lifetime occupational exposure to dust, gases or fumes was reported by 52% of the subjects (63% in men, 41% in women. Textile industry was the most frequently reported job in relation to these exposures (39%. Chronic cough, expectoration and wheeze were more prevalent in exposed subjects with odds ratios ranging from 1.7 to 2.0 being highest among never-smokers (2.1 to 4.3. Lung function differences between exposed and unexposed subjects were dependent on duration of exposure, but not on smoking habits. Subjects exposed more than 15 years to dusts, gases or fumes had lower lung function values (FEV1 -80 ml, 95% confidence interval (CI -186 to 26; MMEF -163 ml, CI -397 to 71; FEV1/FVC ratio -1.7%, CI -3.3 to -0.2 than non-exposed. Conclusion Chronic bronchitis symptoms and airflow obstruction are associated with occupational exposures in a population with a high employment in the textile industry. Lung function impairment was related to the duration of occupational exposure, being independent of the effect of smoking.

    Full Text Available Abstract Background The aim of this study was to investigate the quality of life in Croatian homeland war veterans who suffer from post-traumatic stress disorder and chronic low back pain (LBP. Methods A total of 369 participants were included, classified in four study groups: those with post-traumatic stress disorder (PTSD; N = 59, those with both PTSD and lower back pain (PTSD+LBP; N = 80, those with isolated LBP (N = 95 and controls (N = 135. WHOQOL-BREF survey was used in the estimation of quality of life. The data were analysed using statistical methods and hierarchical clustering. Results The results indicated a general pattern of lowering quality of life in participants with both psychological (PTSD and physical (LBP burden. The average overall quality of life was 2.82 ± 1.14 for the PTSD+LBP group, 3.29 ± 1.28 for the PTSD group, 4.04 ± 1.25 for the LBP group and 4.48 ± 0.80 for the controls (notably, all the pair-wise comparisons were significantly different at the level of P Conclusions The results of this study reiterate strong impact of PTSD on quality of life, which is additionally reduced if the patient also suffers from LBP. PTSD remains a substantial problem in Croatia, nearly two decades after the beginning of the 1991-1996 Homeland war.

    Full Text Available KDIGO (Kidney Disease: Improving Global Outcomes is an international nonprofit organization devoted to “improve the care and outcomes of kidney disease patients worldwide through promoting coordination, collaboration, and integration of initiatives to develop and implement clinical practice guidelines.” The mineral and bone disorder (MBD in patients with chronic kidney disease (CKD has been the first area of interest of KDIGO international initiative. KDIGO guidelines on CKD-MBD were published in 2009 with the intent to modify the previous KDOQI guidelines that had failed to consistently change the global outcome of CKD patients. After the publication of KDOQI guidelines for bone metabolism and disease in 2003, a large number of observational data emerged in literature linking disordered mineral metabolism with adverse clinical outcomes. Notwithstanding this large body of observational data, a paucity of evidence from high-quality clinical trials was available for the development of KDIGO guidelines. Herein, a summary will be provided of the most important findings of KDIGO guidelines regarding the diagnostic workup and clinical monitoring of CKD-MBD patients.

    Chronic myelomonocytic leukemia is similar to but a separate entity from both myeloproliferative neoplasms and myelodysplastic syndromes, and shows either myeloproliferative or myelodysplastic features. We ask whether this distinction may have a molecular basis. We established the gene expression profiles of 39 samples of chronic myelomonocytic leukemia (including 12 CD34-positive) and 32 CD34-positive samples of myelodysplastic syndromes by using Affymetrix microarrays, and studied the status of 18 genes by Sanger sequencing and array-comparative genomic hybridization in 53 samples. Analysis of 12 mRNAS from chronic myelomonocytic leukemia established a gene expression signature of 122 probe sets differentially expressed between proliferative and dysplastic cases of chronic myelomonocytic leukemia. As compared to proliferative cases, dysplastic cases over-expressed genes involved in red blood cell biology. When applied to 32 myelodysplastic syndromes, this gene expression signature was able to discriminate refractory anemias with ring sideroblasts from refractory anemias with excess of blasts. By comparing mRNAS from these two forms of myelodysplastic syndromes we derived a second gene expression signature. This signature separated the myelodysplastic and myeloproliferative forms of chronic myelomonocytic leukemias. These results were validated using two independent gene expression data sets. We found that myelodysplastic chronic myelomonocytic leukemias are characterized by mutations in transcription/epigenetic regulators (ASXL1, RUNX1, TET2) and splicing genes (SRSF2) and the absence of mutations in signaling genes. Myelodysplastic chronic myelomonocytic leukemias and refractory anemias with ring sideroblasts share a common expression program suggesting they are part of a continuum, which is not totally explained by their similar but not, however, identical mutation spectrum.

  1. Dasatinib targets B-lineage cells but does not provide an effective therapy for myeloproliferative disease in c-Cbl RING finger mutant mice.

    Directory of Open Access Journals (Sweden)

    Johanna M Duyvestyn

    Full Text Available This study aimed to determine whether the multi-kinase inhibitor dasatinib would provide an effective therapy for myeloproliferative diseases (MPDs involving c-Cbl mutations. These mutations, which occur in the RING finger and linker domains, abolish the ability of c-Cbl to function as an E3 ubiquitin ligase and downregulate activated protein tyrosine kinases. Here we analyzed the effects of dasatinib in a c-Cbl RING finger mutant mouse that develops an MPD with a phenotype similar to the human MPDs. The mice are characterized by enhanced tyrosine kinase signaling resulting in an expansion of hematopoietic stem cells, multipotent progenitors and cells within the myeloid lineage. Since c-Cbl is a negative regulator of c-Kit and Src signaling we reasoned that dasatinib, which targets these kinases, would be an effective therapy. Furthermore, two recent studies showed dasatinib to be effective in inhibiting the in vitro growth of cells from leukemia patients with c-Cbl RING finger and linker domain mutations. Surprisingly we found that dasatinib did not provide an effective therapy for c-Cbl RING finger mutant mice since it did not suppress any of the hematopoietic lineages that promote MPD development. Thus we conclude that dasatinib may not be an appropriate therapy for leukemia patients with c-Cbl mutations. We did however find that dasatinib caused a marked reduction of pre-B cells and immature B cells which correlated with a loss of Src activity. This study is therefore the first to provide a detailed characterization of in vivo effects of dasatinib in a hematopoietic disorder that is driven by protein tyrosine kinases other than BCR-ABL.

    Čolović Milica

    2010-01-01

    Full Text Available Introduction. An acquired somatic mutation V617F in Janus kinase 2 gene (JAK2 is the cause of uncontrolled proliferation in patients with myeloproliferative neoplasms. It is known that uncontrolled myeloid cell proliferation is also provoked by alteration in other genes, e.g. mutations in receptor tyrosine kinase FLT3 gene. FLT3 represents the most frequently mutated gene in acute myeloid leukaemia. Interestingly, mutated FLT3- ITD (internal tandem duplication protein is a member of the same signalling pathway as JAK2 protein, the STAT5 signalling pathway. STAT5 activation is recognized as important for selfrenewal of haematopoetic stem cells. Objective. The aim of this study was the detection of JAK2- V617F mutation in patients with myeloproliferative neoplasms. Additionally, we investigated the presence of FLT3-ITD mutation in JAK2-V617F-positive patients in order to shed the light on the hypothesis of a similar role of these two molecular markers in haematological malignancies. Methods. Using allele-specific PCR, 61 patients with known or suspected diagnosis of myeloproliferative neoplasms were tested for the presence of JAK2-V617F mutation. Samples that were positive for JAK2 mutation were subsequently tested for the presence of FLT3-ITD mutation by PCR. Results. Eighteen of 61 analysed patients were positive for JAK2-V617F mutation. Among them, 8/18 samples were diagnosed as polycythaemia vera, and 10/18 as essential thrombocythaemia. None of JAK2-V617F-positive patient was positive for FLT3-ITD mutation. Conclusion. This study suggests that one activating mutation is sufficient for aberrant cell proliferation leading to malignant transformation of haematopoetic stem cell.

    Since endothelial cells can be targeted by large contrast-carrying particles, molecular imaging of cerebrovascular cell activation is highly promising to evaluate the underlying inflammation of the central nervous system (CNS). In this study, we aimed to demonstrate that molecular magnetic resonance imaging (MRI) of cerebrovascular cell activation can reveal CNS disorders in the absence of visible lesions and symptoms. To this aim, we optimized contrast carrying particles targeting vascular cell adhesion molecule-1 and MRI protocols through both in vitro and in vivo experiments. Although, pre-contrast MRI images failed to reveal the ongoing pathology, contrast-enhanced MRI revealed hypoperfusion-triggered CNS injury in vascular dementia, unmasked amyloid-induced cerebrovascular activation in Alzheimer's disease and allowed monitoring of disease activity during experimental autoimmune encephalomyelitis. Moreover, contrast-enhanced MRI revealed the cerebrovascular cell activation associated with known risk factors of CNS disorders such as peripheral inflammation, ethanol consumption, hyperglycemia and aging. By providing a dramatically higher sensitivity than previously reported methods and molecular contrast agents, the technology described in the present study opens new avenues of investigation in the field of neuroinflammation.

    Full Text Available Background: Chronic myeloid leukemia (CML is a clonal myeloproliferative expansion of primitive hematopoietic progenitor cells. Materials and Methods: In the present study, CML samples were collected from various hospitals in Amritsar, Jalandhar and Ludhiana. Results: Chromosomal alterations seen in peripheral blood lymphocytes of these treated and untreated cases of CML were satellite associations, double minutes, random loss, gain of C group chromosomes and presence of marker chromosome. No aberrations were observed in control samples. Karyotypic abnormalities have also been noted in the Ph-negative cells of some patients in disease remission. Conclusion: This is a novel phenomenon whose prognostic implications require thorough and systematic evaluation.

    Full Text Available PURPOSE: Non-CML myeloproliferative neoplasms (MPN include essential thrombocythemia (ET, polycythemia vera (PV, and myelofibrosis (MF. Reported median overall survival (OS ranges from a few to several years for MF, a decade or more for ET and PV. The study objective was to compare US survival rates of ET, PV, and MF patients with matched non-MPN/non-cancer controls in a nationally representative database. PATIENTS AND METHODS: Data were taken retrospectively from the Survey, Epidemiology, and End Results (SEER-Medicare linked database. Medicare enrollees with a new SEER MPN diagnosis between Jan 1, 2001 and Dec 31, 2007 were eligible. First MPN diagnosis was required at or after Medicare enrollment to allow for continuous follow-up. Non-MPN/non-cancer control groups were selected from Medicare separately for each MPN subtype and demographically matched to cases at a ratio of 5:1. Survival was determined starting from the case diagnosis date using the Kaplan-Meier method. RESULTS: A total of 3,364 MPN patients (n = 1,217 ET; 1,625 PV; 522 MF met the inclusion criteria and were matched to controls. Mean age was 78.4, 76.1, and 77.4 years for ET, PV, and MF, respectively, and percent female was 63, 50, and 41. Median OS was significantly (p<0.05 lower for MPN cases vs. controls (ET: 68 vs. 101 months; PV: 65 vs. 104; MF: 24 vs. 106. CONCLUSIONS: In the US Medicare population, survival in MF patients was worse than that of patients with ET or PV and significantly worse than matched controls. Survival of patients with ET or PV was substantially inferior to matched controls. These findings have implications for the clinical management of MPN patients and underscore the need for effective therapies in all MPN subtypes.

    The use of biologic drugs has been linked with the paradoxical development of systemic and organ specific autoimmune processes. The aim of this study was to describe the features of biologics-induced autoimmune renal disorders (AIRD) through a systematic review and a cohort study of 707 adult patients affected with Rheumatoid Arthritis (RA), Ankylosing Spondylitis (SA) and Psoriatic Arthritis (PsA). The literature search identified 2687 articles of which 21 were considered relevant for the present study, accounting for 26 case reports. The cohort analysis retrieved 3 cases. According to clinical manifestations and kidney histology the identified AIRD cases were classified as: a) glomerulonephritis associated with systemic vasculitis (GNSV), b) glomerulonephritis in lupus-like syndrome (GNLS), c) isolated autoimmune renal disorders (IARD). Twenty-two out of 29 cases with AIRD were reported in patients affected by RA, 5 in AS and 2 in PsA. The biologic drug most frequently associated with development of AIRD was Etanercept (15 cases, 51.7%), followed by Adalimumab (9 cases, 31.0%) and Infliximab (3 cases, 10.3%) while Tocilizumab and Abatacept were reported in 1 case (3.4%) for each. Thirteen out of 29 (44.8%) cases were classified as affected by IARD, 12 (41.3%) as GNSV and 4 (13.9%) as GNLS. Worse prognosis was associated with GNSV and lack of biologic withdrawal. Although rare, AIRD may be life-threatening and may lead to renal failure and death. If AIRD occurs, biologic drugs must be stopped and patient should be treated according to clinical manifestations and kidney biopsy findings.

    The spontaneously hypertensive rat (SHR) is frequently used as an experimental model for the study of attention deficit hyperactivity disorder (ADHD) since it displays behavioural and neurochemical features of ADHD. Increasing evidence suggests that caffeine might represent an important therapeutic tool for the treatment of ADHD and we recently demonstrated that the acute administration of caffeine improves several learning and memory impairments in adult SHR rats. Here we further evaluated the potential of caffeine in ADHD therapy. Female Wistar (WIS) and SHR rats were treated with caffeine (3mg/kg, i.p.) or methylphenidate (MPD, 2mg/kg, i.p.) for 14 consecutive days during the prepubertal period (post-natal days 25-38) and they were tested later in adulthood in the object-recognition task. WIS rats discriminated all the objects used, whereas SHR were not able to discriminate pairs of objects with subtle structural differences. Chronic treatment with caffeine or MPD improved the object-recognition deficits in SHR rats. Surprisingly, these treatments impaired the short-term object-recognition ability in adult WIS rats. The present drug effects are independent of changes in locomotor activity, arterial blood pressure and body weight in both rat strains. These findings suggest that chronic caffeine treatment during prepubertal period confers long-term cognitive benefits in discriminative learning impairments of SHR, suggesting caffeine as an alternative therapeutic strategy for the early management of ADHD symptoms. Nevertheless, our results also emphasize the importance of a correct diagnosis and the caution in the use of stimulant drugs such as caffeine and MPD during neurodevelopment since they can disrupt discriminative learning in non-ADHD phenotypes.

    Type-2 diabetes mellitus (T2D) represents an important metabolic disorder, firmly connected to obesity and low level of chronic inflammation caused by deregulation of fat metabolism. The convergence of chronic inflammatory signals and nutrient overloading at the endoplasmic reticulum (ER) leads to activation of ER-specific stress responses, the unfolded protein response (UPR). As obesity and T2D are often associated with impaired wound healing, we investigated the role of UPR in the pathologic of diabetic-impaired cutaneuos wound healing. We determined the expression patterns of the three UPR branches during normal and diabetes-impaired skin repair. In healthy and diabetic mice, injury led to a strong induction of BiP (BiP/Grp78), C/EBP homologous protein (CHOP) and splicing of X-box-binding protein (XBP)1. Diabetic-impaired wounds showed gross and sustained induction of UPR associated with increased expression of the pro-inflammatory chemokine macrophage inflammatory protein (MIP)2 as compared to normal healing wounds. In vitro, treatment of RAW264.7 macrophages with tunicamycin, and subsequently stimulation with lipopolysaccharide (LPS) and interferon (IFN)-γ enhances MIP2 mRNA und protein expression compared to proinflammatory stimulation alone. However, LPS/IFNγ induced vascular endothelial growth factor (VEGF) production was blunted by tunicamycin induced-ER stress. Hence, UPR is activated following skin injury, and functionally connected to the production of proinflammatory mediators. In addition, prolongation of UPR in diabetic non-healing wounds aggravates ER stress and weakens the angiogenic phenotype of wound macrophages.

    In industrialized nations and high-income regions of the world, the decline of infectious diseases is paralleled by an increase in allergic, autoimmune and chronic inflammatory diseases (AACID). Changes in lifestyle in westernized societies, which impact individually and collectively on intestinal microbiota, may - at least in part - account for the AACID pandemic. Many disease genes that contribute to AACID encode pattern recognition and signalling molecules in barrier-associated cells. Interactions between gene products and environmental factors depend highly upon the host's state of maturation, the composition of the skin and gut microflora, and exposure to pollutants, antibiotics and nutrients. Inflammatory stress responses, if regulated appropriately, ensure immunity, health and relative longevity; when they are dysregulated, they can no longer be terminated appropriately and thus precipitate AACID. The 99th Dahlem Conference brought together experts of various disciplines (genetics, evolution biology, molecular biology, structural biology, cell biology, immunology, microbiology, nutrition science, epidemiology and clinical medicine) to discuss the multi-faceted relationships between infection, immunity and inflammation in barrier organs and the development of AACID. In Clinical and Experimental Immunology we are presenting a compilation of background papers that formed the basis of discussions. Controversial viewpoints and gaps in current knowledge were examined and new concepts for prevention and treatment of CID were formulated.

    Full Text Available Abstract Background Early trauma-focused cognitive-behavioural therapy (TFCBT holds promise as a preventive intervention for people at risk of developing chronic post-traumatic stress disorder (PTSD. The aim of this review was to provide an updated evaluation of the effectiveness of early TFCBT on the prevention of PTSD in high risk populations. Methods We performed a systematic literature search in international electronic databases (MEDLINE, EMBASE, PsycINFO, CENTRAL, CINAHL, ISI and PILOTS and included randomised controlled trials comparing TFCBT delivered within 3 months of trauma, to alternative interventions. All included studies were critically appraised using a standardised checklist. Two independent reviewers selected studies for inclusion and assessed study quality. Data extraction was performed by one reviewer and controlled by another. Where appropriate, we entered study results into meta-analyses. Results Seven articles reporting the results of five RCTs were included. All compared TFCBT to supportive counselling (SC. The study population was patients with acute stress disorder (ASD in four trials, and with a PTSD diagnosis disregarding the duration criterion in the fifth trial. The overall relative risk (RR for a PTSD diagnosis was 0.56 (95% CI 0.42 to 0.76, 1.09 (95% CI 0.46 to 2.61 and 0.73 (95% CI 0.51 to 1.04 at 3–6 months, 9 months and 3–4 years post treatment, respectively. A subgroup analysis of the four ASD studies only resulted in RR = 0.36 (95% CI 0.17 to 0.78 for PTSD at 3–6 months. Anxiety and depression scores were generally lower in the TFCBT groups than in the SC groups. Conclusion There is evidence for the effectiveness of TFCBT compared to SC in preventing chronic PTSD in patients with an initial ASD diagnosis. As this evidence originates from one research team replications are necessary to assess generalisability. The evidence about the effectiveness of TFCBT in traumatised populations without an ASD

    Full Text Available Chronic myeloid leukemia (CML is a malignant myeloproliferative disorder that originates from a pluripotent stem cell characterized by abnormal release of the expanded, malignant stem cell clone from the bone marrow into the bloodstream. The vast majority of patients with CML present Bcr-Abl transcripts. Lactate dehydrogenase (LDH is considered a biochemical marker common for tumor growth, anaerobic glycolysis and has been considered a poor prognostic factor for acute myeloid leukemia. Therefore, this study aimed to evaluate the concentration of LDH in plasma and the detection of the Bcr-Abl transcripts in patients with CML and healthy donors. We analyzed 22 patients demonstrably diagnosed with CML and 56 healthy donors. LDH concentration in plasma was higher in patients with CML. All patients with CML in this study were under treatment, but even so four patients had the Bcr-Abl (b3a2 transcript in peripheral blood. Two out of the four patients with b3a2 showed higher LDH (486 U L-1 and 589 U L-1. Thus, although the study was conducted with small numbers of samples, it is possible to suggest therapy alteration for two patients who presented transcript b3a2 in the peripheral blood samples and whose LDH concentration was high, in order to improve the disease.Chronic myeloid leukemia (CML is a malignant myeloproliferative disorder that originates from a pluripotent stem cell characterized by abnormal release of the expanded, malignant stem cell clone from the bone marrow into the bloodstream.

We aimed to identify the BOLD signal variability changes of PTSD patients during symptom provocation and compare the brain patterns of BOLD signal variability with those of brain activation.Methods: Twelve PTSD patients and 14 age-matched controls, who all experienced a mining accident, underwent clinical assessment as well as fMRI scanning while viewing trauma-related and neutral pictures. BOLD signal variability and brain activation were respectively examined with standard deviation (SD and general linear model analysis, and compared between the PTSD and control groups. Multiple regression analyses were conducted to explore the association between PTSD symptom severity and these two brain measures across all subjects as well as in the PTSD group.Results: PTSD patients showed increased activation in the middle occipital gyrus compared with controls, and an inverse correlation was found between PTSD

  16. The relationship between chronic whiplash-associated disorder and post-traumatic stress: attachment-anxiety may be a vulnerability factor

    Full Text Available Background: In more than 90% of whiplash accidents a good explanation regarding the association between trauma mechanism, organic pathology, and persistent symptoms has failed to be provided. Objective: We predicted that the severity of chronic whiplash-associated disorder (WAD, measured as number of whiplash symptoms, pain duration, pain-related disability, and degree of somatisation would be associated with the number of post-traumatic stress disorder symptoms (PTSD. Secondly, we expected attachment-anxiety to be a vulnerability factor in relation to both PTSD and WAD. Design: Data were collected from 1,349 women and 360 men suffering from WAD from the Danish Society for Polio, Traffic, and Accident Victims. The PTSD symptoms were measured by the Harvard Trauma Questionnaire. All three core PTSD clusters were included: re-experiencing, avoidance, and hyperarousal. Attachment security was measured along the two dimensions, attachment-anxiety and attachment-avoidance, by the Revised Adult Attachment Scale. Results: PTSD symptoms were significantly related to the severity of WAD. In particular, the PTSD clusters of avoidance and hyperarousal were associated with the number of whiplash symptoms, disability, and somatisation. Attachment-anxiety was significantly related to PTSD symptoms and somatisation but not to pain and disability. A co-morbidity of 38.8% was found between the PTSD diagnosis and WAD, and about 20% of the sample could be characterised as securely attached. Conclusions: The PTSD clusters of avoidance and hyperarousal were significantly associated with severity of WAD. The study emphasises the importance of assessing PTSD symptomatology after whiplash injury. Furthermore, it highlights that attachment theory may facilitate the understanding of why some people are more prone to develop PTSD and WAD than others.For abstract or full text in other languages, please see Supplementary files under Reading Tools online

    Purpose Functional restoration programs (FRPs), for patients with chronic disabling occupational musculoskeletal disorders (CDOMDs), have consistently demonstrated positive socioeconomic treatment outcomes, including decreased psychosocial distress and increased work return. The pre-treatment length of disability (LOD), or time between injury and treatment admission, has been shown to influence FRP work outcomes. Some studies have found that shorter LOD is associated with better work outcomes. However, few studies have actually examined cohorts with LOD duration longer than 18 months. This present study evaluated the effects of extended LOD (beyond 18 months) on important treatment outcomes. Methods A total cohort of 1413 CDOMD patients entered an FRP. Of those, 312 did not complete the program, so they were eliminated from outcome analyses. The 1101 patients who completed the FRP were classified based on LOD: Late Rehabilitation (LR, 3-6 months, n = 190); Chronic Disability (CD, 7-17 months, n = 494); and Late Chronic Disability (LCD). The LCD, in turn, consisted of four separate subgroups: 18-23 months (LCD-18, n = 110); 24-35 months (LCD-24, n = 123); 36-71 months (LCD-36, n = 74); and 72+ months (LCD-72, n = 110). Patients were evaluated upon admission and were reassessed at discharge. Those patients who chose to pursue work goals post-treatment (n = 912) were assessed 1-year later. Results Longer LOD was associated with less likelihood of completing the FRP (p disability group were receiving social security disability benefits. Associations were found between longer LOD and more severe patient-reported pain, disability, and depressive symptoms at treatment admission. At discharge, symptom severity decreased for these patient-reported variables in all LOD groups (p disability. Furthermore, long LOD was a significant predictor for work outcomes at 1 year following FRP discharge. Nevertheless, a large percentage of longer LOD (>24

    Full Text Available The chronic state of whiplash-associated disorder (WAD might be understood as a somatization of existential pain. Intervention aimed to improve quality of life (QOL seemed to be a solution for such situations. The basic idea behind the intervention was holistic, restoring quality of life and relationship with self, in order to diminish tension in the locomotion system, especially the neck. A psychosomatic theory for WAD is proposed. Our treatment was a short 2-day course with teachings in philosophy of life, followed by 6 to 10 individual sessions in gestalt psychotherapy and body therapy (Rosen therapy and Cranio Sacral therapy, followed by a 1-day course approximately 2 months later, closing the intervention. Two independent institutions did the intervention and the assessments. In a randomized, clinically controlled setting, 87 chronic WAD patients were included with a median duration of 37 months from their whiplash accidents. One patient never started. Forty-three had the above intervention (female/male = 36/7, ages 22–49, median 37 years and another 43 were assigned to a nontreated control group (female/male = 35/8, ages 1848, median 38. Six had disability pension and 27 had pending medicolegal issues in each group. Effect variables were pain in neck, arm, and/or head; measures of quality of life and daily activities; as well as general physical or mental health. Wilcoxon test for between-groups comparisons with intention-to-treat analyses was conducted; the square curve paradigm testing for immediate improvements of health and quality of life was also used. The groups were comparable at baseline. From the intervention group, 11 dropped out during the intervention (4 of those later joined the follow-up investigation, 22 of the remaining 32 graduated the course, and 35 of the 43 controls did as well. Approximately 3 months later, we found no clinically relevant or significant increase in any effect measure. The above version of a quality

    It is often difficult to pass an expert opinion in cases of chronic back pain. This article analyses the differential diagnostic considerations related to coding various causes in line with ICD-10. It emphasises the I importance of making a careful distinction between orthopoedic and psychiatric conditions and disorders. Simultaneous coding of orthopoedic and psychiatric illnesses and disorders based on a distinct cluster of symptoms necessitates an interdisciplinary approach that consistently applies the ICD-10 definitions of mental an behavioural disorders in order to clearly identify the main reason for a functional impairment in the insurance and sociomedical context. Persistant somatoform pain disorder with somatic and psychological factors (ICD-10 F45.41) should be regarded as related to the underlying disease and be used primarily as an additional and descriptive diagnosis.

    Delusional disorders are divided in French nosography into three clinical disease entities: paranoid delusions, psychose hallucinatoire chronique, and paraphrenia. Their common characteristics are a late start, a chronic evolution, no cognitive impairment and no dissociation. Delusio- nal syndrome is often at the forefront with a predominant mechanism characterizing each disorder (interpretation for paranoid delusions, hallucination for psychose hallucinatoire chronique and imagination for paraphrenia). Although these disorders are less sensitive to the medication than schizophrenia, care is based on second generation antipsychotic treatment, in association with psychotherapy and social care. The aim of treatment is to alleviate delusion intensity to improve global functioning and to prevent violent incidents or suicide attempt.

    The 8p11 myeloproliferative syndrome (EMS) is an aggressive neoplasm caused by the fusion of various partner genes to fibroblast growth factor receptor 1 (FGFR1). Various FGFR1 fusions are associated with subtly distinct disease phenotypes. Here, we report a new translocation at the FGFR1 locus in a patient who carried t(1;8)(q25;p11.2) and presented with myeloproliferative neoplasm-like symptoms. The patient was characterized by myeloid hyperplasia of bone marrow, markedly elevated numbers of monocytes, and normal to mildly elevated eosinophils. Initial fluorescent in situ hybridization analysis confirmed that FGFR1 in this patient was disrupted. Subsequent analysis led to the identification of a novel translocation, in which exon 23 of the translocated promoter region (TPR) gene at chromosome band 1q25 was fused to exon 13 of FGFR1 (RefSeq NM_0231102.2). The TPR portion of the fusion protein contains putative functional motifs including an N-terminal TprMet domain, nuclear pore complexes associating domain, and multiple coiled-coil domains. It is likely that one or more of the motifs from TPR contribute to dimerization, resulting in constitutive activation of the FGFR1 kinase domain. Our results further support a critical role of FGFR1 in the pathogenesis of EMS and may lead to more accurate diagnosis and potential targeted therapy.

    AIM: To explore the prevalence of autoimmune gastritis in chronic hepatitis C virus (HCV) patients and the influence of α-intefferon (IFN) treatment on autoimmune gastritis.METHODS: We performed a prospective study on 189patients with positive anti-HCV and viral RNA enrolled in a 12-month IFN protocol. We evaluated: a) the baseline prevalence of autoimmune gastritis, b) the impact of IFN treatment on development of biochemical signs of autoimmune gastritis (at 3, 6 and 12 months), c) the evolution after IFN withdrawal (12 months) in terms of anti-gastric-parietal-cell antibodies (APCA), gastrin, anti-thyroid, and anti-non-organ-specific antibodies.RESULTS: APCA positivity and 3-fold gastrin levels were detected in 3 (1.6 %) and 9 (5 %) patients, respectively, at baseline, in 25 (13 %) and 31 (16 %) patients at the end of treatment (both P<0.001, vs baseline), and in 7 (4 %) and 14 (7 %) patients 12 months after withdrawal (P=0.002and ,P=0.01 respectively, vs baseline; P=not significant vs end of treatment). The development of autoimmune gastritis was strictly associated with the presence of autoimmune thyroiditis (P =0.0001), no relationship was found with other markers of autoimmunity.CONCLUSION: In HCV patients, IFN frequently precipitates latent autoimmune gastritis, particularly in females. Following our 12-month protocol, the phenomenon generally regressed. Since APCA positivity and high gastrin levels are associated with the presence of antithyroid antibodies,development of autoimmune thyroiditis during IFN treatment may provide a surrogate preliminary indicator of possible autoimmune gastritis to limit the need for invasive examinations.

    It is recognized that monoamine reuptake inhibitors (MARIs) exert beneficial effects in the treatment of major depression and general anxiety disorder. The aim of this study was to identify proteins regulated by this class of antidepressant using a proteome differential profiling approach. Either venlafaxine or fluoxetine was administered systemically to adult rats for 2 weeks, and protein patterns from rat hippocampal cytosolic extracts were compared by two-dimensional gel electrophoresis. Silver-stained protein spots displaying differential expression were identified by mass spectrometry. Thirty-three protein spots were modulated by both drug treatments compared to controls. The classification of several proteins that were sorted by function suggested convergent pathway activities for both MARIs at the post-receptor level. These included proteins associated with neurogenesis (insulin like growth factor 1 (IGF-1), glia maturation factor [GMF]-beta), outgrowth/maintenance of neuronal processes (hippocampal cholinergic neurostimulating peptide [HCNP], PCTAIRE-3), and with neural regeneration/axonal guidance collapsin response mediator protein (CRMP-2) systems. Other modulated proteins indicated an increase in neuronal vesicular cell trafficking and synaptic plasticity (Ras-related protein 4a (Rab4a), Ras-related protein 1b (Rab1b), heat shock protein 10 [HSP10]), as well as neurosteroidogenic (hydroxysteroid sulfotransferase A) and possible anti-apoptotic (dimethylargininase-1 L-N,N-dimethylarginine dimethylaminohydrolase-1 [DDAH-1], pyruvate dehydrogenase-E1 [PDH-E1], antioxidant protein-2 [AOP-2]) pathway-mediated regulatory events. Parallel studies to investigate further the effects of venlafaxine and fluoxetine on adult hippocampal neurogenesis in vivo by quantitative bromodeoxyuridine immunolabeling revealed a significant drug-induced increase in the proliferation rate and long-term survivability of progenitor stem cells located in the subgranular zone.

    We investigated relationships between spiritual well-being (SWB), intrinsic religiosity (IR), and suicidal behavior in 45 Croatian war veterans with chronic posttraumatic stress disorder and 32 healthy volunteers. Compared with the volunteers, the veterans had significantly lower SWB scores (p = 0.000) and existential well-being (EWB) scores (p = 0.000). Scores on the religious well-being (RWB) subscale (p = 0.108) and the IR scale did not differ significantly between the groups (p = 0.803). Veterans' suicidality inversely correlated with SWB (p = 0.000), EWB (p = 0.000), RWB (p = 0.026), and IR (p = 0.041), with the association being stronger for the EWB subscale than for the RWB subscale. Veterans who had attempted suicide at least once in their lifetime had significantly higher Suicidal Assessment Scale scores and lower EWB scores than veterans who never attempted suicide. Low EWB scores may imply an increased risk of suicidality. Some religious activities were more frequent among the veterans than among the healthy volunteers, possibly reflecting the veterans' increased help-seeking behavior due to poor EWB.

    Awareness generation and modulation may depend on a balanced information integration and differentiation across default mode network (DMN) and external awareness networks (EAN). Neuromodulation approaches, capable of shaping information processing, may highlight residual network activities supporting awareness, which are not detectable through active paradigms, thus allowing to differentiate chronic disorders of consciousness (DoC). We studied aftereffects of repetitive transcranial magnetic stimulation (rTMS) by applying graph theory within canonical frequency bands to compare the markers of these networks in the electroencephalographic data from 20 patients with DoC. We found that patients' high-frequency networks suffered from a large-scale connectivity breakdown, paralleled by a local hyperconnectivity, whereas low-frequency networks showed a preserved but dysfunctional large-scale connectivity. There was a correlation between metrics and the behavioral awareness. Interestingly, two persons with UWS showed a residual rTMS-induced modulation of the functional correlations between the DMN and the EAN, as observed in patients with MCS. Hence, we may hypothesize that the patients with UWS who demonstrate evidence of residual DMN-EAN functional correlation may be misdiagnosed, given that such residual network correlations could support covert consciousness.

The clinimetric aspects of Eysenck's two big personality factors (neuroticism and extraversion) were originally identified by principal component analysis but have been insufficiently analysed with item response theory models. Their relationship to states of melancholia and anxiety was subsequently analysed. Method. Patients with chronic idiopathic pain disorder were included in the study. The nonparametric item response model (Mokken) was compared to the coefficient alpha to validate the anxiety and depression subscales within the neuroticism scale and the extraversion and introversion subscales within the extraversion scale. When measuring states of depression and anxiety, the Melancholia Scale and the Hamilton Anxiety Scale were used. Results. We identified acceptable subscales of anxiety and depression in the Eysenck factor of neuroticism and extraversion versus introversion subscales within the Eysenck factor of extraversion. Focusing on the item of "Does your mood often go up and down?" we showed a statistically significant association with melancholia and anxiety for patients with a positive score on this item. Conclusion. Within the Eysenck factor of neuroticism it is important to differentiate between the anxiety and depression subscales. The clinimetric analysis of the Eysenck factor of extraversion identified valid subscales.

    Full Text Available Although traditional Chinese medicine (TCM and Western medicine have evolved on distinct philosophical foundations and reasoning methods, an increasing body of scientific data has begun to reveal commonalities. Emerging scientific evidence has confirmed the validity and identified the molecular mechanisms of many ancient TCM theories. One example is the concept of “Kidneys Govern Bones.” Here we discuss the molecular mechanisms supporting this theory and its potential significance in treating complications of chronic kidney disease (CKD and diabetes mellitus. Two signaling pathways essential for calcium-phosphate metabolism can mediate the effect of kidneys in bone homeostasis, one requiring renal production of bioactive vitamin D and the other involving an endocrine axis based on kidney-expressed Klotho and bone-secreted fibroblast growth factor 23. Disruption of either pathway can lead to calcium-phosphate imbalance and vascular calcification, accelerating metabolic bone disorder. Chinese herbal medicine is an adjunct therapy widely used for treating CKD and diabetes. Our results demonstrate the therapeutic effects and underlying mechanisms of a Chinese herbal formulation, Shen-An extracts, in diabetic nephropathy and renal osteodystrophy. We believe that the smart combination of Eastern and Western concepts holds great promise for inspiring new ideas and therapies for preventing and treating complications of CKD and diabetes.

    Chronic kidney disease-mineral and bone disorder (CKD-MBD), is sequential pathophysiology that starts in the very early stages of CKD. Three major aspects of CKD-MBD are laboratory abnormalities, bone abnormalities and vascular calcification. In dialysis patients, the prevalence of death due to cardiovascular disease accounts for more than 40% of all-cause mortality. Therefore, arteriosclerosis with vascular calcification may be an important pathophysiological mechanism in the development of cardiovascular disease. Vascular calcification is known to be an important risk factor influencing mortality in CKD patients. A number of studies have suggested a close association between serum FGF23 concentration and the risks of mortality, cardiovascular disease vascular calcification as well as CKD progression. Renal insufficiency leads to decline in klotho level and impaired phosphate excretion. However serum phosphate levels are maintained in the normal range by up regulation of FGF23 and PTH in early CKD stage. Early treatment intervention is necessary to improve the prognosis of the CKD patient.

    Chronic neutrophilic leukemia (CNL) is a rare myeloproliferative disorder characterized by a proliferation mainly of mature neutrophils. The prognosis is generally poor and an optimal therapeutic strategy remains to be determined. Allogeneic hematopoietic stem cell transplantation (HSCT) is expected to be the only curative therapy so far. We report a 46-year-old male with progressive CNL who underwent bone marrow transplantation from an HLA-matched unrelated donor. After engraftment was achieved on day 35, relapse of CNL was confirmed on day 50. The progression of CNL was very rapid afterward and infiltration to the central nervous system was observed. The Janus Kinase 2 (JAK2) V617F homozygous mutation was detected from the peripheral blood or bone marrow samples throughout the clinical course. From comparison with reports of successful HSCT for CNL in the literature, it was inferred that HSCT should be performed in a stable status before progression. Furthermore, JAK2 V617F-positive CNL may contain an aggressive disease entity in contrast to previous reports. Accumulation of experiences is required to establish a definite role of HSCT in the treatment of CNL and a prognostic significance of JAK2 mutation in CNL.

    Full Text Available Abstract Background Patients with Ph-negative myeloproliferative neoplasms (MPN, such as polycythemia vera (PV, essential thrombocythemia (ET, and primary myelofibrosis (PMF, are at increased risk for thrombosis/thromboembolism and major bleeding. Due to the morbidity and mortality of these events, antiplatelet and/or anticoagulant agents are commonly employed as primary and/or secondary prophylaxis. On the other hand, disease-related bleeding complications (i.e., from esophageal varices are common in patients with MPN. This analysis was performed to define the frequency of such events, identify risk factors, and assess antiplatelet/anticoagulant therapy in a cohort of patients with MPN. Methods The MPN registry of the Study Alliance Leukemia is a non-interventional prospective study including adult patients with an MPN according to WHO criteria (2008. For statistical analysis, descriptive methods and tests for significant differences as well as contingency tables were used to identify the odds of potential risk factors for vascular events. Results MPN subgroups significantly differed in sex distribution, age at diagnosis, blood counts, LDH levels, JAK2V617F positivity, and spleen size (length. While most thromboembolic events occurred around the time of MPN diagnosis, one third of these events occurred after that date. Splanchnic vein thrombosis was most frequent in post-PV-MF and MPN-U patients. The chance of developing a thromboembolic event was significantly elevated if patients suffered from post-PV-MF (OR 3.43; 95 % CI = 1.39–8.48 and splenomegaly (OR 1.76; 95 % CI = 1.15–2.71. Significant odds for major bleeding were previous thromboembolic events (OR = 2.71; 95 % CI = 1.36–5.40, splenomegaly (OR = 2.22; 95 % CI 1.01–4.89, and the administration of heparin (OR = 5.64; 95 % CI = 1.84–17.34. Major bleeding episodes were significantly less frequent in ET patients compared to other MPN subgroups

    Pulmonary hypertension (PH), a serious disorder with a high morbidity and mortality rate, is known to occur in a number of unrelated systemic diseases. Several hematological disorders such as sickle cell disease, thalassemia and myeloproliferative diseases develop PH which worsens the prognosis. Associated oxidant injury and vascular inflammation cause endothelial damage and dysfunction. Pulmonary vascular endothelial damage/dysfunction is an early event in PH resulting in the loss of vascular reactivity, activation of proliferative and antiapoptotic pathways leading to vascular remodeling, elevated pulmonary artery pressure, right ventricular hypertrophy and premature death. Hemolysis observed in hematological disorders leads to free hemoglobin which rapidly scavenges nitric oxide (NO), limiting its bioavailability, and leading to endothelial dysfunction. In addition, hemolysis releases arginase into the circulation which converts L-arginine to ornithine, thus bypassing NO production. Furthermore, treatments for hematological disorders such as immunosuppressive therapy, splenectomy, bone marrow transplantation, and radiation have been shown to contribute to the development of PH. Recent studies have shown deregulated iron homeostasis in patients with cardiopulmonary diseases including pulmonary arterial hypertension (PAH). Several studies have reported low iron levels in patients with idiopathic PAH, and iron deficiency is an important risk factor. This article reviews PH associated with hematological disorders and its mechanism; and iron homeostasis and its relevance to PH. PMID:28070238

    Psychosomatic disorders involving depression and anxiety co‐occur frequently enough that they can be conceptualized as elements within a broad spectrum of internalizing disorders. Patterns of comorbidity among common mental disorders can be understood from the perspective of a model that regards mood ,anxiety and somatization disorders as elements with an internalizing spectrum of disorder ,and substance use and antisocial behavior disorder as elements within a separate externalizing spectrum of disorder. In this article ,we evaluate the possibility of linking this model to literatures on chronic pain. Evidence from psychosocial and biological perspectives points out the mechanisms that link chronic pain to internalizing disorder ,and such evidence indicates that the internalizing‐externalizing model may provide a useful framework for suggesting new directions for research on connections between chronic pain and mood ,anxiety and related disorders and traits.%常见的心身障碍共病可以理解为一种新的精神疾病结构模型:情绪障碍、抑郁、焦虑及躯体化障碍等归为内化性疾病谱系的组成元素,物质滥用和反社会行为障碍归为外化性疾病谱系的组成元素。本文分析探讨评估慢性疼痛与这一模型的联系。社会心理和生物学的研究证据表明慢性疼痛与内化性障碍密切相关,提示内化-外化性疾病模型可以作为一个有效的研究架构,为探讨慢性疼痛与情感、抑郁焦虑及其他相关精神障碍的关联共病机制提供新的研究方向和新思路。
