Prevalence and costs of multinutrution in hospitalized patients; the PREDyCES study

Justificación y objetivos: El estudio PREDyCES® tuvo dos objetivos principales. Primero, analizar la prevalencia de desnutrición hospitalaria (DH) en España tanto al ingreso como al alta, y segundo, estimar sus costes asociados. Métodos: Estudio nacional, transversal, observacional, multicéntrico, en condiciones de práctica clínica habitual que evaluó la presencia de desnutrición hospitalaria al ingreso y al alta mediante el NRS-2002®. Una extensión del estudio analizó la incidencia de complicaciones asociadas a la desnutrición, el exceso de estancia hospitalaria y los costes sanitarios asociados a la DH. Resultados: La prevalencia de desnutrición observada según el NRS-2002® fue del 23.7%. El análisis multivariante mostró que la edad, el género, la presencia de enfermedad oncológica, diabetes mellitus, disfagia y la polimedicación fueron los factores principales que se asociaron a la presencia de desnutrición. La DH se asoció a un incremento de la estancia hospitalaria, especialmente en aquellos pacientes que ingresaron sin desnutrición y que presentaron desnutrición al alta (15.2 vs 8.0 días; p < 0.001), con un coste adicional asociado de 5.829€ por paciente. Conclusiones: Uno de cada cuatro pacientes en los hospitales españoles se encuentra desnutrido. Esta condición se asocia a un exceso de estancia hospitalaria y costes asociados, especialmente en pacientes que se desnutren durante su hospitalización. Se debería generalizar el cribado nutricional sistemático con el objetivo de implementar intervenciones nutricionales de conocida eficacia.

Niveles de nitrógeno y su fraccionamiento en el cultivo del gladiolo para suelos Ferralíticos Rojos

El objetivo del presente estudio fue evaluar niveles crecientes de nitrógeno y momentos de aplicación del fertilizante nitrogenado en el cultivo del gladiolo. La experiencia se desarrolló en el Instituto de Investigaciones Hortícolas Liliana Dimitrova (Municipio de Quivicán, La Habana, Cuba), en un suelo Ferralítico Rojo, entre los meses de octubre y febrero de las campañas 2004/2005 y 2005/2006. Se evaluaron los componentes de la calidad de las espigas y del material de plantación, así como el efecto de los tratamientos en el estado nutricional de la planta y en la vida en anaquel de las espigas. No se observaron diferencias entre las dosis de nitrógeno y los momentos de aplicación del fertilizante en las variables de calidad de la espiga y del cormo. No obstante, con la variante 70 kg ha-1 de N, aplicada ½ en plantación y ½ a los 60 días posteriores, se logra un mayor porcentaje de espigas ubicadas en las categorías comerciales y un menor número de tallos florales de calidad inferior. En cuanto al estado nutricional de la plantación, existe una relación positiva entre los niveles y los contenidos foliares de nitrógeno aplicados.

Beyond Conditionality versus Cooperation: Power and Resistance in the Case of EU Mobility Partnerships and Swiss Migration Partnerships

Migration partnerships (MPs) have become a key instrument in global migration governance. In contrast to traditional unilateral approaches, MPs emphasize a more comprehensive and inclusive tackling of migration issues between countries of origin, transit, and destination. Due to this cooperation-oriented concept, most of the existing studies on MPs neglect power questions within partnerships in line with the official discourse, reflecting a broader trend in the international migration governance literature. Others take an instrumentalist view in analysing the power of partnerships or focus on soft power. Illustrated with the examples of the European Mobility Partnerships (EU MPs) and the Swiss Migration Partnerships (CH MPs), we conduct an analysis based on a concept of productive power drawing on post-structural and post-colonial insights. Our main argument is that in contrast to their seemingly consent-oriented and technical character, MPs are sites of intense (discursive) struggles, and (re-)produce meanings, subjects, and resistances. A productive power analysis allows us to move beyond the dichotomy in the literature between coercion and cooperation, as well as between power and resistance more broadly.

Relaciones nitrógeno-potasio en fertirriego para el cultivo protegido del tomate en suelo Ferralítico Rojo

El objetivo del presente trabajo fue evaluar el efecto de soluciones nutritivas en el fertirriego, con diferentes relaciones entre el nitrógeno y el potasio, en la productividad y calidad de los frutos del tomate (híbrido Hazera 3019), en suelo Ferralítico Rojo. La experiencia se desarrolló en el Instituto de Investigaciones Hortícolas Liliana Dimitrova (La Habana, Cuba). Se estudiaron cuatro soluciones nutritivas, que se diferenciaron en su relación NO3-+NH4+/K+ en términos de meq L-1 (N/K), con una relación K+/Ca2++Mg2+ en todas las variantes de 0,75. Los tratamientos resultantes (T1, 1:0,45; T2, 1:0,60 o testigo de producción, T3, 1:0,75 y T4, 1:0,90) fueron distribuidos en un diseño completamente aleatorizado con cuatro réplicas. La variación de la relación N/K en la solución nutritiva influyó en el rendimiento, la calidad externa y la vida en anaquel de los frutos de tomate, sin afectar la calidad bromatológica. La mejor combinación entre estructura del rendimiento y calidad de los frutos se obtiene con la relación N/K 1:0,75, al presentar rendimientos superiores en las categorías de calidad comercial extra, primera y extra más primera, así como frutos con mayor firmeza y grosor del endocarpio, menor porcentaje de frutos fuera de norma y valores inferiores de pérdidas postcosecha.

Changes in lipoprotein lipase modulate tissular energy supply during stress

We studied the variations caused by stress in lipoprotein lipase (LPL) activity, LPL-mRNA, and local blood flow in LPL-rich tissues in the rat. Stress was produced by body immobilization (Immo): the rat's limbs were taped to metal mounts, and its head was placed in a plastic tube. Chronic stress (2 h daily of Immo) decreased total LPL activity in mesenteric and epididymal white adipose tissue (WAT) and was accompanied by a weight reduction of these tissues. In limb muscle, heart, and adrenals, total LPL activity and mRNA levels increased, and, in plasma, LPL activity and mass also increased. Acute stress (30-min Immo) caused a decrease in total LPL activity only in retroperitoneal WAT and an increase in preheparin plasma active LPL, but the overall weight of this tissue did not vary significantly. We propose an early release of the enzyme from this tissue into the bloodstream by some unknown extracellular pathways or other local mechanisms. These changes in this key energy-regulating enzyme are probably induced by catecholamines. They modify the flow of energy substrates between tissues, switching the WAT from importer to exporter of free fatty acids and favoring the uptake by muscle of circulating triacylglycerides for energy supply. Moreover, we found that acute stress almost doubled blood flow in all WAT studied, favoring the export of free fatty acids.

IFN Stimulated Gene Expression in the Liver is a Better Predictor of Treatment Response in Chronic Hepatitis C than the IL28B (IFN lambda 3) Genotype

BACKGROUND: Therapy of chronic hepatitis C (CHC) with pegIFNα/ribavirin achieves a sustained virologic response (SVR) in ∼55%. Pre-activation of the endogenous interferon system in the liver is associated with non-response (NR). Recently, genome-wide association studies described associations of allelic variants near the IL28B (IFNλ3) gene with treatment response and with spontaneous clearance of the virus. We investigated if the IL28B genotype determines the constitutive expression of IFN stimulated genes (ISGs) in the liver of patients with CHC. METHODS: We genotyped 93 patients with CHC for 3 IL28B single nucleotide polymorphisms (SNPs, rs12979860, rs8099917, rs12980275), extracted RNA from their liver biopsies and quantified the expression of IL28B and of 8 previously identified classifier genes which discriminate between SVR and NR (IFI44L, RSAD2, ISG15, IFI22, LAMP3, OAS3, LGALS3BP and HTATIP2). Decision tree ensembles in the form of a random forest classifier were used to calculate the relative predictive power of these different variables in a multivariate analysis. RESULTS: The minor IL28B allele (bad risk for treatment response) was significantly associated with increased expression of ISGs, and, unexpectedly, with decreased expression of IL28B. Stratification of the patients into SVR and NR revealed that ISG expression was conditionally independent from the IL28B genotype, i.e. there was an increased expression of ISGs in NR compared to SVR irrespective of the IL28B genotype. The random forest feature score (RFFS) identified IFI27 (RFFS = 2.93), RSAD2 (1.88) and HTATIP2 (1.50) expression and the HCV genotype (1.62) as the strongest predictors of treatment response. ROC curves of the IL28B SNPs showed an AUC of 0.66 with an error rate (ERR) of 0.38. A classifier with the 3 best classifying genes showed an excellent test performance with an AUC of 0.94 and ERR of 0.15. The addition of IL28B genotype information did not improve the predictive power of the 3-gene classifier. CONCLUSIONS: IL28B genotype and hepatic ISG expression are conditionally independent predictors of treatment response in CHC. There is no direct link between altered IFNλ3 expression and pre-activation of the endogenous system in the liver. Hepatic ISG expression is by far the better predictor for treatment response than IL28B genotype.

A genome-wide association study of anorexia nervosa.

Anorexia nervosa (AN) is a complex and heritable eating disorder characterized by dangerously low body weight. Neither candidate gene studies nor an initial genome-wide association study (GWAS) have yielded significant and replicated results. We performed a GWAS in 2907 cases with AN from 14 countries (15 sites) and 14 860 ancestrally matched controls as part of the Genetic Consortium for AN (GCAN) and the Wellcome Trust Case Control Consortium 3 (WTCCC3). Individual association analyses were conducted in each stratum and meta-analyzed across all 15 discovery data sets. Seventy-six (72 independent) single nucleotide polymorphisms were taken forward for in silico (two data sets) or de novo (13 data sets) replication genotyping in 2677 independent AN cases and 8629 European ancestry controls along with 458 AN cases and 421 controls from Japan. The final global meta-analysis across discovery and replication data sets comprised 5551 AN cases and 21 080 controls. AN subtype analyses (1606 AN restricting; 1445 AN binge-purge) were performed. No findings reached genome-wide significance. Two intronic variants were suggestively associated: rs9839776 (P=3.01 × 10(-7)) in SOX2OT and rs17030795 (P=5.84 × 10(-6)) in PPP3CA. Two additional signals were specific to Europeans: rs1523921 (P=5.76 × 10(-)(6)) between CUL3 and FAM124B and rs1886797 (P=8.05 × 10(-)(6)) near SPATA13. Comparing discovery with replication results, 76% of the effects were in the same direction, an observation highly unlikely to be due to chance (P=4 × 10(-6)), strongly suggesting that true findings exist but our sample, the largest yet reported, was underpowered for their detection. The accrual of large genotyped AN case-control samples should be an immediate priority for the field.

Triagem de genótipos de hortaliças para resistência a Meloidogyne enterolobii

O objetivo deste trabalho foi identificar genótipos de alface, batata-doce, feijão, tomate e Capsicum resistentes ao nematoide Meloidogyne enterolobii (Syn. M. mayaguensis) e classificá-los quanto ao grau de resistência. Foram avaliados: 10 genótipos de alface, 8 de batata-doce, 10 de feijão e feijão-vagem, 25 de Capsicum e 6 de tomate. Foram calculados o fator de reprodução e o índice de reprodução, e os genótipos foram classificados quanto ao grau de resistência ao nematoide. Foram observados níveis moderados de resistência na cultivar de feijão Aporé e nos acessos de pimenta, BGH-433 e BGH-4285, e de pimentão, PIM-031, PIX-022I-31-07-02 e PIX-022I-31-13-01. Todos os genótipos de tomate são suscetíveis a M. enterolobii. As cultivares de alface Julia, Hortência, Verônica, Grand Rapids e Babá de Verão, e os clones de batata-doce UFLA07-49 e UFLA07-53 são muito resistentes ao nematoide. A resistência a M. enterolobii aparentemente é mediada por genes diferentes dos que conferem resistência a outras espécies e raças de Meloidogyne.

Cab45 is required for Ca(2+)-dependent secretory cargo sorting at the trans-Golgi network

Ca(2+) import into the lumen of the trans-Golgi network (TGN) by the secretory pathway calcium ATPase1 (SPCA1) is required for the sorting of secretory cargo. How is Ca(2+) retained in the lumen of the Golgi, and what is its role in cargo sorting? We show here that a soluble, lumenal Golgi resident protein, Cab45, is required for SPCA1-dependent Ca(2+) import into the TGN; it binds secretory cargo in a Ca(2+)-dependent reaction and is required for its sorting at the TGN.

Coliform density in oyster culture waters and its relationship with environmental factors

The objective of this work was to evaluate the total and thermotolerant coliform densities in the oyster culture water of Cananeia, SP, Brazil, correlating these densities with environmental variables and tidal variations. Superficial water samples were collected in two tide conditions (spring and neap) from three areas of Cananéia municipality (Mandira, Itapitangui and Cooperostra). The three studied areas showed good conditions for the culture regarding coliform densities. The two tidal conditions differed significantly as to total coliform concentration; however, the same procedure was not performed for thermotolerant coliforms. No correlation was observed between water temperature, pH, and concentrations of total and thermotolerant coliforms. Coliform density was positively correlated with rainfall and negatively correlated with salinity. Spring and neap tides differed significantly as to coliform number. Simple diagnosis of environmental conditions of the crop fields is insufficient to assess water quality of shellfish cultivation. A continuous monitoring program of planted areas is necessary both for the assessment of water quality potential for marine culture and for ensuring safe consumption of seafood, besides constituting an important tool to understand the relationships between contamination and the involved environmental variables.

Kahdessa kuvantamisyksikössä tapahtuneet muutokset liikelaitokseen liittymisen yhteydessä vuosina 2005-2007

Opinnäytetyön tarkoituksena oli kuvata kahdessa kuvantamisyksikössä liikelaitokseen liittymisen yhteydessä työn organisoinnissa, työnjaossa ja toimintakulttuurissa tapahtuneita muutoksia. Lisäksi tavoitteena oli kuvata kesän 2007 aikana odotettavissa olleet toiminnalliset muutokset. Opinnäytetyö on osa Helsingin ammattikorkeakoulu Stadiassa käynnissä olevaa Työn organisointi ja työnjako röntgenosastoilla -hanketta. Opinnäytetyö on laadullinen tutkimus. Aineisto hankittiin haastattelemalla kahden kuvantamisyksikön osastonhoitajia ja apulaisosastonhoitajia. Haastattelut suoritettiin teemahaastatteluina ja analysoitiin sisällönanalyysillä. Aineisto luokiteltiin kuudeksi eri pääkategoriaksi, jotka ovat: työn johtaminen, työnjako, työnkuva, työtehtävät, kulttuuri sekä yhteistyö ja tiedonkulku. Teoriaosassa organisaatiomuutosta tarkasteltiin muun muassa johtamisen ja kulttuurin näkökulmista. Tulosten mukaan työn johtamisessa muutoksia oli tapahtunut päätöksenteossa ja lähijohtamisessa, ja työnjaossa toimintojen keskittämisessä, työmäärän jakautumisessa ja henkilöstömäärässä. Työnkuvassa ilmeni muutoksia työnkierrossa, vuorotyössä ja kouluttautumisessa, sekä työtehtävissä eri henkilöstöryhmien toimenkuvissa ja vastuualueissa. Kulttuurisia muutoksia oli havaittavissa toimintatavoissa ja -ohjeissa, arvoissa ja asenteissa sekä yhteisöllisyydessä. Muutoksia oli tapahtunut myös yhteistyössä ja tiedonkulussa. Tutkimusta voidaan hyödyntää suunniteltaessa vastaavanlaista organisaatiomuutosta. Tutkimus antaa tietoa siitä, mihin asioihin organisaatiomuutos vaikuttaa kuvantamisyksiköissä ja mitä muutoksia on odotettavissa liikelaitokseen liittymisen yhteydessä. Tutkimuksen tuloksia hyödynnetään hankkeen jatkotutkimuksessa, jossa tarkastellaan, onko palveluiden laadussa ja työtyytyväisyydessä tapahtunut muutoksia.
