Patients' Desire for Psychological Support When Receiving a Cancer Diagnostic

Cancer patients; Mood disorders; Psychological supportPacients amb càncer; Trastorns de l'estat d'ànim; Suport psicològicPacientes con cáncer; Trastornos del estado de ánimo; Apoyo psicológicoBackground: Factors related to the desire of receiving psychological help in cancer patients are not well known. The aim of this study is to assess the prevalence of patients who would ask for psychological assistance in the first weeks following diagnosis, and to identify their psychosocial and disease-related profile. Method: This cross-sectional study assessed 229 consecutive cancer outpatients at a visit with their oncologist to be informed about the treatment they will receive. Disease-related and medical characteristics were assessed, and patients were asked about their mood states, levels of self-efficacy, and difficulties coping with the disease. Finally, patients were asked about their desire to receive psychological assistance. Results: Only 20% of patients expressed a desire for psychological help. These patients were lower in age and had previous history of mood disorders and reported higher discouragement and coping difficulties. These variables explained 30.6% of variance. Conclusions: Although psycho-oncologists can provide helpful interventions, the percentage of patients interested in receiving psychological assistance in this study is low. Although further studies are needed, results from this study suggest methods that could easily be used by oncologists and nurses to identify patients who would like to receive psychological support

Analysis of Complete Genome Sequence of <i>Acinetobacter</i> <i>baumannii</i> Strain ATCC 19606 Reveals Novel Mobile Genetic Elements and Novel Prophage.

Acinetobacter baumannii isolate ATCC 19606 was recovered in the US prior to 1948. It has been used as a reference and model organism in many studies involving antibiotic resistance and pathogenesis of A. baumannii, while, until recently, a complete genome of this strain was not available. Here, we present an analysis of the complete 3.91-Mbp genome sequence, generated via a combination of short-read sequencing (Illumina) and long-read sequencing (MinION), and show it contains two small cryptic plasmids and a novel complete prophage of size 41.2 kb. We also characterised several regions of the ATCC 19606 genome, leading to the identification of a novel cadmium/mercury transposon, which was named Tn6551. ATCC 19606 is an antibiotic-sensitive strain, but a comparative analysis of all publicly available ST52 strains predicts a resistance to modern antibiotics by the accumulation of antibiotic-resistance genes via plasmids in recent isolates that belong to this sequence type

Analysis Procedure of a Previous Planning Organization - The Area of the Seminary School of Corpus Christi in Valencia, Spain

The Seminary School of Corpus Christi is one of the most important buildings in the city of Valencia, Spain. The building has contributed with the University of Valencia to the urban transformation of the neighborhood in which they are located throughout its 4004-year history. In this study is proposed a five-phase methodology for the study of urban organization before its construction. We achieved to develop an original hypothesis of how seminary school block plots were organized through the study and analysis of their purchase contracts, which are dated between 1586 and 1601. It is interesting to note the plot acquisition sequence and its influence in the building construction process.Lerma Elvira, C.; Mas Tomas, MDLA.; Blasco García, V. (2013).

Mechanisms of Tolerance and Resistance to Chlorhexidine in Clinical Strains of Klebsiella pneumoniae Producers of Carbapenemase: Role of New Type II Toxin-Antitoxin System, PemIK

Although the failure of antibiotic treatment is normally attributed to resistance, tolerance and persistence display a significant role in the lack of response to antibiotics. Due to the fact that several nosocomial pathogens show a high level of tolerance and/or resistance to chlorhexidine, in this study we analyzed the molecular mechanisms associated with chlorhexidine adaptation in two clinical strains of Klebsiella pneumoniae by phenotypic and transcriptomic studies. These two strains belong to ST258-KPC3 (high-risk clone carrying β-lactamase KPC3) and ST846-OXA48 (low-risk clone carrying β-lactamase OXA48). Our results showed that the K. pneumoniae ST258-KPC3CA and ST846-OXA48CA strains exhibited a different behavior under chlorhexidine (CHLX) pressure, adapting to this biocide through resistance and tolerance mechanisms, respectively. Furthermore, the appearance of cross-resistance to colistin was observed in the ST846-OXA48CA strain (tolerant to CHLX), using the broth microdilution method. Interestingly, this ST846-OXA48CA isolate contained a plasmid that encodes a novel type II toxin/antitoxin (TA) system, PemI/PemK. We characterized this PemI/PemK TA system by cloning both genes into the IPTG-inducible pCA24N plasmid, and found their role in persistence and biofilm formation. Accordingly, the ST846-OXA48CA strain showed a persistence biphasic curve in the presence of a chlorhexidine-imipenem combination, and these results were confirmed by the enzymatic assay (WST-1).The State Plan for R+D+I 2013–2016 National Plan for Scientific Research, Technological Development and Innovation 2008–2011 PI16/01163 and PI19/00878ISCIII-Deputy General Directorate for Evaluation and Promotion of Research - European Regional Development Fund “A way of Making Europe” and Instituto de Salud Carlos III FEDER, Spanish Network for the Research in Infectious Diseases REIPI, RD16/0016/0001, RD16/CIII/0004/0002 and RD16/0016/0006The Study Group on Mechanisms of Action and Resistance to Antimicrobials, GEMAR

Experiencias en investigación para la enseñanza de la construcción arquitectónica

Exposición oral presentada en la sesión dedicada a Formación,Doctorado y Posgrado en las IV Jornadas Internacionales sobre Investigación en Arquitectura y Urbanismo.En la adaptación hacia el Proceso de Bolonia, las experiencias en investigación para la enseñanza, en nuestro caso la de la construcción arquitectónica, deben llevarnos a idear nuevos métodos participativos y educativos para que el elevado número de alumnos que concurren puedan ser formados, educados y evaluados eficazmente. Al mismo tiempo, en una época convulsa como la actual, de cambios vertiginosos y con una visión del mundo distinta a la que nosotros pudiéramos tener cuando fuimos educados, deberemos trasladar la imagen del mundo actual a la docencia, y viceversa, educando a los estudiantes desde su propia óptica y utilizando las redes sociales, para motivar a una generación desmotivada por los sistemas convencionales de enseñanza. Hace falta, pues, innovación, porque necesitamos gente bien formada no solamente en contenidos, sino en actitudes y en resolución de problemas, que faciliten nuevas combinaciones productivas en el mundo real.Blasco García, V.; Mas Tomas, MDLA.; Lerma Elvira, C.

International Physical Activity Questionnaire Short Form and accelerometer-assessed physical activity: concurrent validity using six cut-points in HF patients

Aims Physical activity (PA) is an important target for improving clinical outcomes in heart failure (HF) patients. Nonetheless, assessing the daily PA profile in this population is a challenging task, traditionally performed using self-report questionnaires such as the International PA Questionnaire Short Form (IPAQ-SF). This study aimed to evaluate the concurrent validity of the IPAQ-SF and accelerometer-assessed PA using six published cut-points in patients with HF and reduced or mildly reduced ejection fraction. Methods and results The concordance between the IPAQ-SF and a hip-worn accelerometer regarding daily time spent performing moderate to vigorous PA in bouts of at least 10 min was assessed in 53 participants for seven consecutive days using six different cut-points (Barnett, Dibben, Mark, Sanders, Troiano, and Vaha-Ypya). Spearman’s correlation and Bland–Altman plots were used to evaluate concurrent validity between methods. Regressions were used to study the association between patient variables, wear protocol (waking hour or 24 h), and absolute bias. The kappa index was used to evaluate the concordance between IPAQ-SF and accelerometry for classifying patients as active or non-active. All analyses were re-run using non-bouted metrics to investigate the effect of bouted versus non-bouted analysis. The IPAQ-SF and accelerometry showed low to negligible correlation (ρ = 0.12 to 0.37), depending on the cut-point used. The regression analysis showed that the absolute bias was higher in participants following the waking-hour protocol at all cut-points except Dibben’s (P ≤ 0.007). The concordance between the two methods to classify patients as active and non-active was low when using Mark (κ = 0.23) and Barnett (κ = 0.34) cut-points and poor for the remaining cut-points (κ = 0.03 to 0.18). The results of the sensitivity analysis showed negligible to low correlation using non-bouted metrics (ρ = 0.27 to 0.33). Conclusions Moderate to vigorous PA measures using IPAQ-SF and accelerometers are not equivalent, and we do not encourage researchers to use IPAQ-SF alone when assessing PA in HF patients. Moreover, applying personalized collection and processing criteria is important when assessing PA in HF patients. We recommend following the 24 h protocol and selecting cut-points calibrated in patients with cardiovascular diseases. Finally, it is necessary to develop a new tailored questionnaire that considers walking intensity and is adjusted to the current World Health Organisation recommendations, which use non-bouted metrics

Fyn knock-down prevents levodopa-induced dyskinesia in a mouse model of parkinson’s disease

Dopamine replacement by levodopa (L-DOPA) is the most widely used therapy for Parkinson’s disease (PD), however patients often develop side effects, known as L-DOPA-induced dyskinesia (LID), that usually need therapeutic intervention. There are no suitable therapeutic options for LID, except for the use of the NMDA receptor (NMDA-R) antagonist amantadine, which has limited efficacy. The NMDA-R is indeed the most plausible target to manage LID in PD and recently the kinase Fyn, one of its key regulators, became a new putative molecular target involved in LID. The aim of this work was to reduce Fyn expression to alleviate LID in a mouse model of PD. We performed intrastriatal delivery of a designed micro-RNA against Fyn (miRNA-Fyn) in 6-OHDA-lesioned mice treated with L-DOPA. The miRNA-Fyn was delivered either before or after L-DOPA exposure to assess its ability to prevent or revert dyskinesia. Preadministration of miRNA-Fyn reduced LID with a concomitant reduction of FosB-DFosB protein levels, a marker of LID, as well as decreased phosphorylation of the NR2B-NMDA subunit, which is a main target of Fyn. On the other hand, post-L-DOPA delivery of miRNA-Fyn was less effective to revert already established dyskinesia, suggest-ing that early blocking of Fyn activity might be a more efficient therapeutic approach. Together, our results provide proof of concept about Fyn as a plausible therapeutic target to manage LID, and validate RNA si-lencing as a potential approach to locally reduce striatal Fyn, rising new perspectives for RNA therapy interventions in PD.Fil: Bordone, Melina Paula.

Comprehension of architectural construction through multimedia active learning

This study presents an investigation about the use of multimedia procedures applied to architectural construction teaching. We have applied current technological resources, aiming to rationalize and optimize the active learning process. The experience presented to students is very simple and yet very effective. It has consisted in a simulation of an actual building situation, so that they may participate more actively in their learning experience. Conclusions are extremely positive because students surprisingly involve themselves, and they are able to visualize and understand much better the reality of the construction, which increases their motivation and consequently reinforces their learning.Mas Tomas, MDLA.; Blasco García, V.; Lerma Elvira, C.; Angulo Ibáñez, Q.

Lower Locus Coeruleus MRI intensity in patients with late-life major depression

Background: The locus coeruleus (LC) is the major noradrenergic source in the central nervous system. Structural alterations in the LC contribute to the pathophysiology of different neuropsychiatric disorders, which may increase to a variable extent the likelihood of developing neurodegenerative conditions. The characterization of such alterations may therefore help to predict progression to neurodegenerative disorders. Despite the LC cannot be visualized with conventional magnetic resonance imaging (MRI), specific MRI sequences have been developed to infer its structural integrity. Methods: We quantified LC signal Contrast Ratios (LCCRs) in late-life major depressive disorder (MDD) (n = 37, 9 with comorbid aMCI), amnestic Mild Cognitive Impairment (aMCI) (n = 21, without comorbid MDD), and healthy controls (HCs) (n = 31), and also assessed the putative modulatory effects of comorbidities and other clinical variables. Results: LCCRs were lower in MDD compared to aMCI and HCs. While no effects of aMCI comorbidity were observed, lower LCCRs were specifically observed in patients taking serotonin/norepinephrine reuptake inhibitors (SNRIs). Conclusion: Our results do not support the hypothesis that lower LCCRs characterize the different clinical groups that may eventually develop a neurodegenerative disorder. Conversely, our results were specifically observed in patients with late-life MDD taking SNRIs. Further research with larger samples is warranted to ascertain whether medication or particular clinical features of patients taking SNRIs are associated with changes in LC neurons
