Unraveling EU Policies: the ““Common Basic Principles”” and the ““European Integration Fund”” as a technology of government

this paper is about EU “soft policies” on immigrant integration. It analyzes the “Common Basic Principles” (CBPs) and the “European Integration Fund” (EIF), two devices that have been recently established within this framework. It adopts the theoretical perspective of the “anthropology of policy” and “governmentality studies”. It shows the context of birth of the aforementioned devices, as well as their functioning and the assessment done by the actors implied in the elaboration/implementation/evaluation of the related policies. It is based both on documentary research as well as direct observation and interviews done to the actors implied. It concludes that the PBC and the EIF should be considered as a “technology of government”, that strives to align the conduct of the actors with the governmental aims, as well as it produces specific practices and knowledge. It also underlines an intrinsic feature of many policies: their “congenital failure”, since they are (often) disputed and resignified by situated actors, who are embedded in asymmetrical power relations.

Environmental, lifestyle, and familial/ethnic factors associated with myeloproliferative neoplasms

Myeloproliferative neoplasms (MPNs) are characterized by overproduction of mature functional blood cells and are often associated with an acquired genetic mutation of Janus Kinase 2V617F. The etiology of MPNs remains unknown. The aim of this article was to review and collate all known published data investigating environmental and lifestyle factors associated with MPNs. Medline, Embase, PubMed, Cochrane, and Web of Science were systematically searched using terms for MPNs and observational study designs to identify studies investigating the risk factors for MPNs published before March 2010. Of 9,156 articles identified, 19 met the selection criteria. Although the studies exhibited heterogeneity, in case definitions, study design, and risk factors investigated, several themes emerged. A strong association was found with Jewish descent, and with a family history of MPNs. Autoimmune conditions, specifically Crohn's disease, were more common in patients with MPNs. Certain occupational groups were significantly associated with MPNs including occupations with potential exposure to benzene and/or petroleum. Blood donation was associated with an increased risk of polycythemia vera specifically. The vast heterogeneity in studies identified as part of this review suggests that large scale systematic assessment of etiological factors associated with MPNs is warranted.

Community-acquired infections and their association with myeloid malignancies

Introduction: Antigenic stimulation is a proposed aetiologic mechanism for many haematological malignancies. Limited evidence suggests that community-acquired infections may increase the risk of acute myeloid leukaemia (AML) and myelodysplastic syndrome (MDS). However, associations with other myeloid malignancies including chronic myeloid leukaemia (CML) and myeloproliferative neoplasms (MPNs) are unknown.

Materials and methods: Using the Surveillance, Epidemiology and End Result (SEER)-Medicare database, fourteen community-acquired infections were compared between myeloid malignancy patients [AML (n=8489), CML (n=3626) diagnosed 1992-2005; MDS (n=3072) and MPNs (n=2001) diagnosed 2001-2005; and controls (200,000 for AML/CML and 97,681 for MDS/MPN]. Odds ratios (ORs) and 95% confidence intervals were adjusted for gender, age and year of selection excluding infections diagnosed in the 13-month period prior to selection to reduce reverse causality.

Results: Risk of AML and MDS respectively, were significantly associated with respiratory tract infections, bronchitis (ORs 1.20 [95% CI: 1.14-1.26], 1.25 [95% CI: 1.16-1.36]), influenza (ORs 1.16 [95% CI: 1.07-1.25], 1.29 [95% CI: 1.16-1.44]), pharyngitis (ORs 1.13 [95% CI: 1.06-1.21], 1.22 [95% CI: 1.11-1.35]), pneumonia (ORs 1.28 [95% CI: 1.21-1.36], 1.52 [95% CI: 1.40-1.66]), sinusitis (ORs 1.23 [95% CI: 1.16-1.30], 1.25 [95% CI: 1.15-1.36]) as was cystitis (ORs 1.13 [95% CI: 1.07-1.18], 1.26 [95% CI: 1.17-1.36]). Cellulitis (OR 1.51 [95% CI: 1.39-1.64]), herpes zoster (OR 1.31 [95% CI: 1.14-1.50]) and gastroenteritis (OR 1.38 [95% CI: 1.17-1.64]) were more common in MDS patients than controls. For CML, associations were limited to bronchitis (OR 1.21 [95% CI: 1.12-1.31]), pneumonia (OR 1.49 [95% CI: 1.37-1.62]), sinusitis (OR 1.19 [95% CI: 1.09-1.29]) and cellulitis (OR 1.43 [95% CI: 1.32-1.55]) following Bonferroni correction. Only cellulitis (OR 1.34 [95% CI: 1.21-1.49]) remained significant in MPN patients. Many infections remained elevated when more than 6 years of preceding claims data were excluded.

Discussion: Common community-acquired infections may be important in the malignant transformation of the myeloid lineage. Differences in the aetiology of classic MPNs and other myeloid malignancies require further exploration.

Polycythaemia-inducing mutations in the erythropoietin receptor (EPOR):mechanism and function as elucidated by epidermal growth factor receptor-EPOR chimeras

Primary familial and congenital polycythaemia (PFCP) is a disease characterized by increased red blood cell mass, and can be associated with mutations in the intracellular region of the erythropoietin (EPO) receptor (EPOR). Here we explore the mechanisms by which EPOR mutations induce PFCP, using an experimental system based on chimeric receptors between epidermal growth factor receptor (EGFR) and EPOR. The design of the chimeras enabled EPOR signalling to be triggered by EGF binding. Using this system we analysed three novel EPOR mutations discovered in PFCP patients: a deletion mutation (Del1377-1411), a nonsense mutation (C1370A) and a missense mutation (G1445A). Three different chimeras, bearing these mutations in the cytosolic, EPOR region were generated; Hence, the differences in the chimera-related effects are specifically attributed to the mutations. The results show that the different mutations affect various aspects related to the signalling and metabolism of the chimeric receptors. These include slower degradation rate, higher levels of glycan-mature chimeric receptors, increased sensitivity to low levels of EGF (replacing EPO in this system) and extended signalling cascades. This study provides a novel experimental system to study polycythaemia-inducing mutations in the EPOR, and sheds new light on underlying mechanisms of EPOR over-activation in PFCP patients.

How common are myeloproliferative neoplasms? A systematic review and meta-analysis

Myeloproliferative neoplasms (MPNs) are a heterogeneous group of diseases including polycythemia vera (PV), essential thrombocythemia (ET), and primary(idiopathic) myelofibrosis (PMF). In this systematic review, we provide a comprehensive report on the incidence and prevalence of MPNs across the globe. Electronic databases (PubMed, EMBASE, MEDLINE, and Web of Science) were searched from their inception to August 2012 for articles reporting MPN incidence or prevalence rates. A random effects meta-analysis was undertaken to produce combined incidence rates for PV, ET, and PMF. Both heterogeneity and small study bias were assessed. Thirty-four studies were included. Reported annual incidence rates ranged from 0.01 to 2.61, 0.21 to 2.27, and 0.22 to 0.99 per 100,000 for PV, ET, and PMF, respectively. The combined annual incidence rates for PV, ET, and PMF were 0.84, 1.03, and 0.47 per 100,000. There was high heterogeneity across disease entities (I(2) 97.1-99.8%) and evidence of publication bias for ET and PMF (Egger test, P = 50.007 and P ≤ 0.001, respectively).The pooled incidence reflects the rarity of MPNs. The calculated pooled incidence rates do not reflect MPN incidence across the globe due to the high unexplained heterogeneity. Improved, widespread registration of MPNs would provide better information for global comparison of the incidence and prevalence of MPNs.

Genome-wide meta-analysis identifies 11 new loci for anthropometric traits and provides insights into genetic architecture

Approaches exploiting trait distribution extremes may be used to identify loci associated with common traits, but it is unknown whether these loci are generalizable to the broader population. In a genome-wide search for loci associated with the upper versus the lower 5th percentiles of body mass index, height and waist-to-hip ratio, as well as clinical classes of obesity, including up to 263,407 individuals of European ancestry, we identified 4 new loci (IGFBP4, H6PD, RSRC1 and PPP2R2A) influencing height detected in the distribution tails and 7 new loci (HNF4G, RPTOR, GNAT2, MRPS33P4, ADCY9, HS6ST3 and ZZZ3) for clinical classes of obesity. Further, we find a large overlap in genetic structure and the distribution of variants between traits based on extremes and the general population and little etiological heterogeneity between obesity subgroups.
