Advanced breast cancer clinical nursing curriculum: review and recommendations

Purpose The needs and concerns of patients with advanced breast cancer are changing at every phase of the care intervention. Management and coordination of hospital resources and services are also steadily evolving. The objective of the present expert report is to define a new oncology nursing role specialising in advanced breast cancer, to help guide patients throughout the whole healthcare itinerary. Methods A group of eight experts in oncology nursing and medical oncology defined the content index of the curriculum document. A systematic review of bibliography was carried out, and the relevant contents were extracted. Based on these contents and the participants’ experience recommendations were formulated and validated through a Delphi questionnaire and a participative meeting. Results The advanced breast cancer clinical nurse (ABCCN) should develop a clinical, psychosocial role focused on coordinating patients in the healthcare network. The nurse would be in charge of evaluating and supervising the care administered and the healthcare resources used. The ABCCN should be aware and participate in the protocols and available resources, be able to solve conflicts, deal with burn-out signs and have clinical, coaching and team-working abilities. The proposed curriculum provides a specific process for the care of patients, as well as an implementation process. Conclusions The ABCCN’s role is crucial to assume the best care and the optimisation of available resources. This review and consensus document provides the required tools for the implementation in hospitalsThe development of this work has been possible thanks to the financial support of Novartis Oncolog

Influencia de diferentes tratamientos de riego sobre la composición volátil de vinos elaborados con las variedades blancas “Cigüente” y “Verdejo”

En este trabajo se han estudiado los efectos de diferentes tratamientos de régimen hídrico sobre la composición aromática de los vinos elaborados con uva de las variedades blancas Cigüente (en Badajoz) y Verdejo (en Valladolid). Los tratamientos de riego estudiados para Cigüente fueron: CiNR (no regado), CiPR (déficit preenvero, regado al 25% hasta envero y después al 75%), CIPO (déficit postenvero. 75% hasta envero y después al 25%) y CiT (riego máximo durante toda la temporada). Para Verdejo los tratamientos de riego fueron VeNR (no regado), VeRS (riego al 50% del testigo hasta vendimia) y VeT (testigo, 50% ETo, riego máximo). Los mostos obtenidos de las diferentes variedades y tratamientos se sulfitaron con 50 mg/L de SO2, se inocularon con la levadura neutra EC1118 (Lallemand) y su fermentación se llevó a cabo a temperatura controlada. La composición volátil de los vinos elaborados a partir de cada tratamiento fue analizada mediante GC-MS. Se identificaron y cuantificaron 42 compuestos en Verdejo y 36 en Cigüente, que se agruparon en ocho familias aromáticas: alcoholes superiores, alcoholes en C6, ésteres, acetatos, ácidos, fenoles, lactonas y compuestos carbonilados. A nivel global no se encontraron diferencias significativas entre tratamientos de riego en ninguna de las variedades de estudio, sin embargo se observó una tendencia al aumento de concentración en los tratamientos no regados (NR). En el análisis por familias de compuestos volátiles, se hallaron pocas diferencias significativas entre tratamientos. En el caso de Cigüente, se observó un efecto significativo del riego sobre las familias de lactonas y compuestos carbonilados, ambas familias representadas por un único compuesto volátil (γ- butirolactona y acetoina respectivamente). Por otra parte, en Verdejo los tratamientos de riego únicamente tuvieron influencia significativa sobre la familia de fenoles volátiles, representada por dos compuestos (4-vinilgüaiacol y 4-vinilfenol). En ambos casos, Verdejo y Cigüente, la mayor concentración de estas familias de compuestos volátiles fue observada en los tratamientos no regados (NR). En general, en el resto de las familias de compuestos volátiles analizadas no se observaron diferencias significativas, aunque se observó una tendencia hacia una mayor concentración en los tratamientos no regados (NR)

Molecular characterization of dissolved organic matter linked to microbial (Bacteria and Archaea) diversity in the main water masses of the Eastern North Atlantic Ocean

The microbe-dissolved organic matter (DOM) interactions include microbial uptake and DOM reworking and release, affecting the composition of the heterogeneous DOM pool. In turns, this distinct DOM composition can select for microbial assemblages. We investigated the diversity of microbial (both Bacteria and Archaea) communities (combining Illumina tag sequencing of 16S rRNA gen -amplicon sequencing variants, ASVs- and metagenomics) and the chemodiversity of dissolved organic molecules (extracted by solid phase extraction and analyzed by Fourier Transform Ion Cyclotron Resonance Mass Spectrometry, FT-ICR-MS) in the Eastern North Atlantic Ocean off the Galician coast (43oN, 9o-15oW). Sampling ranged from 100 m to 5000 m, thereby encompassing a wide variety of water masses with contrasting origins and different aging. Applying diversity ecological metrics to both organic compounds and ASVs, we found that microbial diversity and richness were negatively correlated with DOM concentration and chemo-diversity. Besides, our results demonstrated the link between this trend and water mass aging, which enhances biosphere taxonomic diversity but reduces molecular variety. DOM diversity, decreasing along the water mass aging gradient, would likely reflect the persistence of the most refractory molecules, generated as by- product of the DOM degradation by microbes. In two PCoAs based on the metagenomic data, combined PCoA axis 1 and PCoA axis 2, explained the 80% and 20% of the microbial gene ́s structural variability among water masses. The oldest water masses, originated at high latitudes, such as NADW and LDW, were associated to higher abundance of genes involved in metabolism of aromatic compound. Intermediate waters such as ENACWst were related to sulphur/iron/phosphorous metabolism related genes. Surface waters were linked to genes involved in photosynthesis, autotrophy and cell division. Taken together, the observed increase of DOM homogenization along water mass aging was associated to differences in the functional diversity of microbial communities

The HDAC7-TET2 epigenetic axis is essential during early B lymphocyte development

Correct B cell identity at each stage of cellular differentiation during B lymphocyte development is critically dependent on a tightly controlled epigenomic landscape. We previously identified HDAC7 as an essential regulator of early B cell development and its absence leads to a drastic block at the pro-B to pre-B cell transition. More recently, we demonstrated that HDAC7 loss in pro-B-ALL in infants associates with a worse prognosis. Here we delineate the molecular mechanisms by which HDAC7 modulates early B cell development. We find that HDAC7 deficiency drives global chromatin de-condensation, histone marks deposition and deregulates other epigenetic regulators and mobile elements. Specifically, the absence of HDAC7 induces TET2 expression, which promotes DNA 5-hydroxymethylation and chromatin de-condensation. HDAC7 deficiency also results in the aberrant expression of microRNAs and LINE-1 transposable elements. These findings shed light on the mechanisms by which HDAC7 loss or misregulation may lead to B cell-based hematological malignancies.FUNDING: Spanish Ministry of Economy and Competitiveness (MINECO) [SAF2017-87990-R]; Spanish Ministry of Science and Innovation (MICINN) [EUR2019-103835]; Josep Carreras Leukaemia Research Institute (IJC, Badalona, Barcelona); IDIBELL Research Institute (L’Hospitalet de Llobregat, Barcelona); A.M. is funded by the Spanish Ministry of Science, Innovation and Universities, which is part of the Agencia Estatal de Investigacion (AEI) [PRE2018-083183] (cofunded by the European Social Fund]; OdB. was funded by a Juan de la Cierva Formacion Fellowship from the Spanish Ministry of Science, Innovation and Universities [FJCI-2017-32430]; Postdoctoral Fellowship from the Asociacion Española Contra el Cáncer (AECC) ´ Foundation [POSTD20024DEBA]; B.M. is awardee of the Ayudas para la formacion del profesorado universitario [FPU18/00755, Ministerio de Universidades]; B.M.J. is funded by La Caixa Banking Foundation Junior Leader project [LCF/BQ/PI19/11690001]; FEDER/Spanish Ministry of Science and Innovation [RTI2018-094788-A-I00]; L.T.-D. is funded by the FPI Fellowship [PRE2019- 088005]; L.R. is funded by an AGAUR FI fellowship [2019FI-B00017]; J.L.S. is funded by ISCIII [CP19/00176], co-funded by ESF, ‘Investing in your future’ and the Spanish Ministry of Science, Innovation and Universities [PID2019-111243RA-I00].

La enseñanza de la lengua de signos en el Espacio Europeo de Educación Superior: Adaptaciones al Marco Común Europeo de Referencia para las Lenguas

La red de investigación que, desde la Universidad de Alicante, analiza la enseñanza de la lengua de signos española (LSE) en el marco del Espacio Europeo de Educación Superior (EEES), se ha articulado en torno a tres ejes: la propia enseñanza de la lengua y la cultura de la Comunidad Sorda española en el ámbito universitario y, más concretamente, en la Universidad de Alicante; el aprendizaje por parte del alumnado que ha cursado esta materia, y el papel de las intérpretes de lengua de signos que desarrollan su labor en este contexto. En los tres casos, presentamos la investigación que hemos llevado a cabo desde la red gracias a la colaboración de profesorado, alumnado e intérpretes, y que supone una completa panorámica de la situación actual de la LSE en el EEES. Una de las principales conclusiones es la necesidad de armonizar su enseñanza bajo las directrices europeas de enseñanza de idiomas que dicta el Marco Común Europeo de Referencia para las Lenguas (MCER, 2001), lo cual presupone una estandarización lingüística de la LSE que aún está en vías de desarrollo

Evaluation of a new, rapid, simple test for the detection of influenza virus

BACKGROUND: Influenza virus infections are responsible for significant morbidity and mortality in both pediatric and adult populations worldwide. Rapid and accurate diagnosis of influenza is necessary for appropriate patient management during the influenza season and for optimal utilization of anti-influenza therapy. We prospectively tested the accuracy of a simple and rapid diagnostic method. METHODS: Ninety-eight samples (nasal and pharyngeal swabs) from patients with upper respiratory tract infection symptoms who presented to primary healthcare centres in Barcelona (Spain) were prospectively analyzed. The samples were collected as part of influenza surveillance program. Samples that had enough volume to make the new test after aliquoting the amount needed to perform routine tests were included. None of the samples were pre-selected as a result of their status in relation to influenza virus. Samples were analyzed by in-house real-time PCR and Alere™ i Influenza A & B (Alere™ i), which uses isothermal amplification of nucleic acids for the qualitative detection of influenza A and B in nasal swabs transported in viral transport media. The two techniques were compared by positive percent agreement (PPA) and negative percent agreement (NPA). Statistical analysis was performed with Stata. RESULTS: Of the 98 samples analysed 90 were concordant; 46 (46.9%) were positive and 44 (44.9%) were negative. Five samples showed invalid results with the Alere™ i test and could be not re-tested due to insufficient sample volume and were not included in the final statistical analysis. In the 93 remaining samples, the Alere™ i test showed 97% of accuracy having correctly classified 90 samples. We obtained discordant results in 3 samples (3%). The PPA was 93.8% for influenza A and 94.1% for influenza B, and NPA was 100% for influenza A and influenza B virus. In addition, the Alere™ i was very rapid (15 minutes or less) and extremely easy to use. CONCLUSIONS: The Alere™ i test provided a good correlation compared to the real-time PCR test for the diagnosis of influenza. Since this method can be performed in minutes, it allows immediate, accurate clinical decisions to prescribe appropriate antiviral treatment or isolation of patients

Consecutive alcoholic fermentations of white grape musts with yeasts immobilized on grape skins : effect of biocatalyst storage and SO2 concentration on wine characteristics

Abstract Saccharomyces cerevisiae yeasts, immobilized by natural adsorption on grape skins, were used to carry out the alcoholic fermentation step of a winemaking process. The viability of the immobilized cells was evaluated by the implementation of 7 successive fermentations of a white grape must containing 30 mg/L of SO2. The time to complete alcoholic fermentation, the physicochemical characteristics of the produced wines (ethanol, glycerol, organic acids, volatile compounds, color) and sensory properties were evaluated. A traditional fermentation with free cells was used as control. Three other fermentations were conducted after storage of the immobilized biocatalyst (30 d, 4 oC), the first one in the same conditions of the earlier assays, and the other two with higher amounts of SO2 (60 mg/L, 90 mg/L). Wines produced with immobilized cells presented physicochemical and sensory characteristics similar to those traditionally produced with free cells. After three consecutive fermentations, chromatic characteristics became similar to those of traditional wines, but the fermentation time had been reduced from 7 d to 4 d. The fermentative process and the characteristics of the produced wines were not significantly affected by the use of higher amounts of SO2. Immobilized biocatalysts could be stored at least one month without losing its activity.Zlatina Genisheva gratefully acknowledges FCT (Contract/grant number: SFRH/BD/48186/2009) and the Project "BioInd - Biotechnology and Bioengineering for improved Industrial and Agro-Food processes", REF.

Effects and mechanisms of mindfulness training and physical exercise on cognition, emotional wellbeing, and brain outcomes in chronic stroke patients : Study protocol of the MindFit project randomized controlled trial

Post-stroke cognitive and emotional complications are frequent in the chronic stages of stroke and have important implications for the functionality and quality of life of those affected and their caregivers. Strategies such as mindfulness meditation, physical exercise (PE), or computerized cognitive training (CCT) may benefit stroke patients by impacting neuroplasticity and brain health. One hundred and forty-one chronic stroke patients are randomly allocated to receive mindfulness-based stress reduction + CCT (n = 47), multicomponent PE program + CCT (n = 47), or CCT alone (n = 47). Interventions consist of 12-week home-based programs five days per week. Before and after the interventions, we collect data from cognitive, psychological, and physical tests, blood and stool samples, and structural and functional brain scans. The effects of the interventions on cognitive and emotional outcomes will be described in intention-to-treat and per-protocol analyses. We will also explore potential mediators and moderators, such as genetic, molecular, brain, demographic, and clinical factors in our per-protocol sample. The MindFit Project is a randomized clinical trial that aims to assess the impact of mindfulness and PE combined with CCT on chronic stroke patients' cognitive and emotional wellbeing. Furthermore, our design takes a multimodal biopsychosocial approach that will generate new knowledge at multiple levels of evidence, from molecular bases to behavioral changes. , identifier NCT04759950
