Un estudio sobre el machismo invisible

El presente trabajo tiene como objetivo principal evaluar las conductas y actitudes encubiertas y sutiles de violencia contra las mujeres y su aceptación social. Para ello, se analizarán algunos mecanismos que sustentan y fomentan el sistema patriarcal (los micromachismos, las creencias sexistas, los estereotipos de géneor, la violencia cultural y estructural, el mito del amor romántico, el sexismo, el seximos ambivalente, etc.). En el estudio de campo se evaluarán las creencias y estereotipos de género de los participantes mediante la adaptación española (Expósito, Moya y Glick, 1998) de la Escala de Sexismo Ambivalene (Glick y Fiske, 1996). Los resultados del estudio de campo muestran que existe una correlación positiiva entre SH y SB que explicaría el sexismo ambivalente, y que en general los hombres y las personas de más de 40 años presentan puntuaciones significativamente superiores respecto a las mujeres y a las personas de menos de 40 años

Identification of a homolog of Arabidopsis DSP4 (SEX4) in chestnut: its induction and accumulation in stem amyloplasts during winter or in response to the cold_

Oligosaccharide synthesis is an important cryoprotection strategy used by woody plants during winter dormancy. At the onset of autumn, starch stored in the stem and buds is broken down in response to the shorter days and lower temperatures resulting in the buildup of oligosaccharides. Given that the enzyme DSP4 is necessary for diurnal starch degradation in Arabidopsis leaves, this study was designed to address the role of DSP4 in this seasonal process in Castanea sativa Mill. The expression pattern of the CsDSP4 gene in cells of the chestnut stem was found to parallel starch catabolism. In this organ, DSP4 protein levels started to rise at the start of autumn and elevated levels persisted until the onset of spring. In addition, exposure of chestnut plantlets to 4 °C induced the expression of the CsDSP4 gene. In dormant trees or cold-stressed plantlets, the CsDSP4 protein was immunolocalized both in the amyloplast stroma and nucleus of stem cells, whereas in the conditions of vegetative growth, immunofluorescence was only detected in the nucleus. The studies indicate a potential role for DSP4 in starch degradation and cold acclimation following low temperature exposure during activity–dormancy transition

Rainbow trout surviving infections of viral haemorrhagic septicemia virus (vhsv) show lasting antibodies to recombinant g protein fragments

P. 929-935Rainbow trout antibodies (Abs) binding to recombinant fragments (frgs) derived from the protein G of the viral haemorrhagic septicemia virus (VHSV)-07.71 strain, could be detected by ELISA (frg-ELISA) in sera from trout surviving laboratory-controlled infections. Abs were detected not only by using sera from trout infected with the homologous VHSV isolate but also with the VHSV-DK-201433 heterologous isolate, which had 13 amino acid changes. Sera from healthy trout and/or from trout surviving infectious haematopoietic necrosis virus (IHNV) infection, were used to calculate cut-off absorbances to differentiate negative from positive sera. Specific anti-VHSV Abs could then be detected by using any of the following frgs: frg11 (56-110), frg15 (65-250), frg16 (252-450) or G21-465. While high correlations were found among the ELISA values obtained with the different frgs, no correlations between any frg- ELISA and complement-dependent 50 % plaque neutralization test (PNT) titres could be demonstrated. Between 4 to 10 weeks after VHSV-infection, more trout sera were detected as positives by using heterologous frg-ELISA rather than homologous PNT. Furthermore, the percentage of positive sera detected by frg11-ELISA increased with time after infection to reach 100 %, while those detected by complement-dependent PNT decreased to 29.4 %, thus confirming that the lack of neutralising Abs does not mean the lack of any anti-VHSV Abs in survivor trout sera. Preliminary results with sera from field samples suggest that further refinements of the frg-ELISA could allow detection of anti-VHSV trout Abs in natural outbreaks caused by different heterologous VHSV isolates.The homologous frg-ELISA method could be useful to follow G immunization attempts during vaccine development and/or to best understand the fish Ab response during VHSV infections. The viral frgs approach might also be used with other fish species and/or viruses.S

Una revisión sistemática de las intervenciones para empoderar al paciente con insuficiencia cardiaca crónica en el entorno hospitalario

El empoderamiento del paciente con insuficiencia cardiaca crónica (ICC) es clave para mejorar su calidad de vida, autonomía, autoestima, nivel de satisfacción y los costes sanitarios. El objetivo fue identificar las intervenciones de enfermería más efectivas para favorecer el empoderamiento del paciente con ICC en el medio hospitalario. Se seleccionaron ocho artículos para revisión (cuatro experimentales, dos cuasi-experimentales y dos revisiones sistemáticas). De su análisis se identificaron tres tipos de intervenciones: educativas, cognitivo-comportamentales y combinadas, siendo estas últimas las más efectivas. Se recomienda el uso del Empowerment Questionnaire como un instrumento válido y fiable para medir el empoderamiento del paciente con ICC hospitalizado. Dada la escasez de estudios, esta revisión aboga por futuras investigaciones que potencien e incluyan intervenciones combinadas mediante una escala válida, fiable y específica para medir el empoderamiento de los pacientes hospitalizados con ICC.The empowerment of patients with chronic heart failure (CHF) is key to improving their quality of life, autonomy, self-esteem, level of satisfaction and healthcare costs. The aim was to identify the most effective nursing interventions to promote the empowerment of patients with CHF in the hospital context. Eight articles were selected for review (four experimental, two quasiexperimental and two systematic reviews). From their analysis, three types of interventions were identified: educational, cognitive-behavioral and combined, the latter being the most effective. The use of the Empowerment Questionnaire is recommended as a valid and reliable instrument to measure the empowerment of chronic hospitalized patients. Given the lack of studies on the phenomenon of interest, this review advocates for future research including combined interventions to empower hospitalized patients with chronic heart failure using a valid, reliable and specific scal

Superiority of a Novel Multifunctional Amorphous Hydrogel Containing Olea europaea Leaf Extract (EHO-85) for the Treatment of Skin Ulcers: A Randomized, Active-Controlled Clinical Trial

This 8-week, multicenter, randomized, active-controlled, observer-blinded clinical trial was designed to demonstrate the accelerating effect on wound healing of the novel Olea europaea leaf extract hydrogel (EHO-85) by comparing it to a widely used amorphous hydrogel. Results showed that EHO-85 significantly accelerated wound healing, regardless of ulcer etiology (pressure, venous leg or diabetic foot) and prognosis, doubling the median wound area reduction compared with a reference amorphous hydrogel (79.4% vs. 39.7%; difference: −39.7%, 95% CI: −71.1 to −21.3%; p < 0.001). The intention-to-treat analysis was conducted on 195 patients from 23 Spanish health centers/nursing homes. This novel treatment balances the ulcer microenvironment by modulating reactive oxygen species and pH. These actions complement the moistening and barrier functions inherent to amorphous hydrogels, whilst also conferring EHO-85 its documented granulation formation and pain relief properties. Furthermore, efficacy was achieved safely and in a cost-efficient manner due to its multi-dose format, which reduced the amount of product needed by 85.8% over 8 weeks compared to single-use hydrogel. The present randomized controlled trial is a relevant milestone in evidence-based practice for being the first to demonstrate (i) the effectiveness of an amorphous hydrogel in accelerating wound healing and (ii) the superiority of a specific hydrogel over another.This research was funded by QUESPER R&D (Córdoba, Spain) and partially by the programme for the Reinforcement of Research Activity in the Clinical Management Units of the Andalusian Health Service (Department of Health.

Genetic variation in interleukin 28B with respect to vertical transmission of hepatitis C virus and spontaneous clearance in HCV-infected children.

La transmisión vertical del virus de la hepatitis C (HCV-VT) es una ruta principal de infección por HCV en niños, pero los factores de riesgo no se comprenden completamente. Este estudio analizó el papel de la interleucina 28B (IL28B) en HCV-VT y en la eliminación espontánea de HCV entre los infantes infectados. Entre 1991 y 2009, se reclutaron 145 madres para este estudio: 100 eran HCV-RNA+ve / VIH negativo (HIV-ve), con 128 niños, y 33 eran HCV-RNA-ve / HCV anticuerpo+ve, con 43 niños. Los infantes fueron evaluados para HCV-RNA al nacer y a intervalos regulares hasta la edad de 6 años. Se determinó IL28B (polimorfismo de nucleótido simple rs12979860) en las madres y los niños. Se asumió HCV-VT cuando los niños presentaron HCV-RNA+ve en dos muestras de sangre consecutivas. Los infantes infectados por HCV-VT se categorizaron como: (1) viremia transitoria con posterior HCV-RNA-ve y sin seroconversión; (2) infección persistente con seroconversión. De las 31 madres con polimorfismo CC, 19 (61%) eran HCV-RNA+ve, mientras que entre las 68 madres con polimorfismo no-CC, 56 (82%) eran HCV-RNA+ve. En total, 26 de 128 (20%) infantes nacidos de madres HCV-RNA+ve adquirieron la infección por HCV, pero solo 9 (7%) estaban crónicamente infectados. La tasa de HCV-VT fue mayor entre las madres con mayor viremia de HCV. No se detectó HCV-VT en las mujeres HCV-RNA-ve. Ni el estado de IL-28 de las madres ni el de los niños se asoció con un mayor riesgo de HCV-VT. Los factores que influyen en la eliminación viral entre los niños infectados fueron el genotipo no-1 y el genotipo CC de IL28B. En la regresión logística, el polimorfismo CC del niño fue el único predictor de la eliminación de HCV en el genotipo-1 de HCV. Conclusión: La alta carga viral materna es el único factor predictivo de HCV-VT. IL28B no juega ningún papel en HCV-VT, pero el polimorfismo CC de IL28B en niños se asocia independientemente con la eliminación espontánea del genotipo-1 de HCV entre los niños infectados.

Antigenic Proteins Involved in Occupational Rhinitis 1 and Asthma Caused by Obeche Wood (Triplochiton Scleroxylon)

Background Obeche wood dust is a known cause of occupational asthma where an IgE-mediated mechanism has been demonstrated. Objective To characterize the allergenic profile of obeche wood dust and evaluate the reactivity of the proteins by in vitro, ex vivo and in vivo assays in carpenters with confirmed rhinitis and/or asthma Materials and methods An in-house obeche extract was obtained, and two IgE binding bands were purified (24 and 12 kDa) and sequenced by N-terminal identity. Specific IgE and IgG, basophil activation tests and skin prick tests (SPTs) were performed with whole extract and purified proteins. CCD binding was analyzed by ELISA inhibition studies. Results Sixty-two subjects participated: 12 with confirmed occupational asthma/rhinitis (ORA+), 40 asymptomatic exposed (ORA−), and 10 controls. Of the confirmed subjects, 83% had a positive SPT to obeche. There was a 100% recognition by ELISA in symptomatic subjects vs. 30% and 10% in asymptomatic exposed subjects and controls respectively (p<0.05). Two new proteins were purified, a 24 kDa protein identified as a putative thaumatin-like protein and a 12 kDa gamma-expansin. Both showed allergenic activity in vitro, with the putative thaumatin being the most active, with 92% recognition by ELISA and 100% by basophil activation test in ORA+ subjects. Cross-reactivity due to CCD was ruled out in 82% of cases. Conclusions Two proteins of obeche wood were identified and were recognized by a high percentage of symptomatic subjects and by a small proportion of asymptomatic exposed subjects. Further studies are required to evaluate cross reactivity with other plant allergens
