    Treballs Finals de Grau de Belles Arts. Facultat de Belles Arts. Universitat de Barcelona, Curs: 2015-16, Tutor: Jaume Ros Valverdú[spa] Esta es la realización artística que quiere sintetizar un recorrido de cuatro años de estudio. Es difícil realizar un tipo de obra de tal índole cuando todavía no has encontrado un camino concreto para recorrer. Es por eso que antes de empezar a construir mi trabajo final de grado he debido mirar atrás para pensar el camino andado y extraer conclusiones. De esta manera, tras haber analizado mi trayectoria artística, podría decirse que hay factores constantes en todo el trabajo realizado, independientemente de si entre ellos hay diferencias a simple vista. Así pues, estos factores serán el hilo conductor que va a guiar la síntesis de mi realización artística. Basándome en la dualidad permanencia/fragilidad he realizado un conjunto de cabezas: un grupo en escayola y tres en bronce. Con ellas quiero reflejar la esencia que permanece en cada ser (las tres de bronce), contrapuesta con la parte más cambiante de cada una (las de escayola). Quiero crear un diálogo entre ellas, en el que el espectador se dé cuenta de esta oposición, cerrando la forma final de la pieza.[eng] This is the artistic realization that attempts to synthesize a four year path of study. It is hard to carry out work of this type when you have not found a specific road to follow yet. It is because of this reason that, before starting my final work, I have had to look back on the path I have followed to reflect and extract conclusions. This way, after having finished analyzing my artistic trajectory, it could be said that there are some constant elements in all of my work, no matter how many differences we find between them at first sight. So, these elements will be the common thread that will guide the sinthesis of my artistic realization. Based on the duality permanence/fragility I have carried out a composition made of heads: a group in plaster and three heads in bronze. With them, I want to show the essence that remains in every being (the bronze ones), in opposition to the changing part (the plaster ones). I want to create a dialogue between them, one in which the spectator realizes this opposition, closing the final form of the piece

    [EN] Chronic non-healing wounds (CNHWs) may be associated with trauma or idiopathic in nature and are difficult to treat. Our objective was to assess the use of platelet-derived growth factor (PDGF) from single-donor platelets (al-PRP), using one freeze-thaw cycle, for treating CNHWs. We conducted a cross-sectional study. A total of 23 CNHWs being treated with al-PRP. The al-PRP treatment can be considered successful in well over half (n = 13, 56.5%) of the wounds. We found that all the wounds treated for up to 7 weeks showed partial or complete healing, while those treated for between 8 and 12 weeks did not show healing, healing again being successful in cases in which treatment was extended to more than 13 weeks (85.7%). Using chi-square tests, this relationship was found to be highly significant (p < 0.001, chi2 = 19.51; p value = 0.00006). Notably, Cramer’s V coefficient was very high (0.921), indicating that the effect size of PRP treatment duration on healing is very large (84.8%). We could suggest that the use of al-PRP in the healing of CNHWs is a promising approach. Further studies with larger sample sizes and long follow-ups are needed to obtain multivariate models to explain which factors favour the healing of ulcers treated with PRPS

    OBJECTIVE: Frailty and heart failure (HF) are cross-sectionally associated. Published longitudinal data are very limited. We sought to investigate associations between frailty and incident HF. METHODS: Prospective study of 1722 men, examined at age 72-91 years. Scores based on the Fried phenotype, Gill index and a novel frailty score, based on the Health Ageing and Body Composition Battery, incorporating slow walking speed, low chair-stand time and subjective difficulty with balance, were calculated. Associations between these scores and incident HF were analysed with Cox proportional hazard modelling. RESULTS: 1445 men with frailty data and without prevalent HF were included. 99 developed HF (mean follow-up 6.1 years). Men scoring 3/3 on our novel frailty score had elevated risk of incident HF (HR 2.77, 95% CI 1.25 to 6.15), which persisted after adjustment for established risk factors and interleukin-6 (HR 3.14, 95% CI 1.35 to 7.31). This risk remained increased, although attenuated, after excluding HF events within 2 years of baseline (HR 2.05, 95% CI 0.61 to 6.92). The frailty phenotype showed a non-significant association with HF (age-adjusted HR 1.92, 95% CI 0.99 to 3.73), which was further attenuated after adjustment for prevalent coronary heart disease and Body mass index (HR 1.60, 95% CI 0.81 to 3.15). Gill-type scores were weakly associated with HF risk after these adjustments (HR 1.31, 95% CI 0.47 to 3.70). CONCLUSION: In these older men, the combination of slow walk speed, low sit-stand time and balance problems were associated with high risk of incident HF, independent of established risk factors and inflammatory markers. However, undiagnosed HF at baseline may still be a confounder. There is a differential association between aspects of the frailty phenotype and incident HF

    © 2018 The Authors. Background-—Although frailty has been associated with increased risks for hospitalization and mortality in chronic heart failure, the precise average effect remains uncertain. We performed a systematic review and meta-analysis to summarize the hazards for mortality and incident hospitalization in patients with heart failure and frailty compared with those without frailty and explored the heterogeneity underlying the effect size estimates. Methods and Results-—MEDLINE, EMBASE, and Cochrane databases were queried for articles published between January 1966 and March 2018. Predefined selection criteria were used. Hazard ratios (HRs) were pooled for meta-analyses, and where odds ratios were used previously, original data were recalculated for HR. Overlapping data were consolidated, and only unique data points were used. Study quality and bias were assessed. Eight studies were included for mortality (2645 patients), and 6 studies were included for incident hospitalization (2541 patients) during a median follow-up of 1.82 and 1.12 years, respectively. Frailty was significantly associated with an increased hazard for mortality (HR, 1.54; 95% confidence interval, 1.34–1.75; P<0.001) and incident hospitalization (HR, 1.56; 95% confidence interval, 1.36–1.78; P<0.001) in chronic heart failure. The Fried phenotype estimated a 16.9% larger effect size than the combined Fried/non-Fried frailty assessment for the end point of mortality (HR, 1.80; 95% confidence interval, 1.41–2.28; P<0.001), but not for hospitalization (HR, 1.57; 95% confidence interval, 1.30–1.89; P<0.001). Study heterogeneity was found to be low (I 2 =0%), and high quality of studies was verified by the Newcastle-Ottawa scale. Conclusions-—Overall, the presence of frailty in chronic heart failure is associated with an increased hazard for death and hospitalization by ≈1.5-fold

    Objectives: Antiplatelet drugs are used to treat and prevent a wide range of cardiovascular pathologies and/or cerebrovascular accidents. Although the use of anticoagulants in dental extractions is highly protocolized, a clear control method has not yet been established for antiplatelet drugs. This study is directed at evaluating the clinical consequences of extractions in patients on antiplatelet therapy. Study design: The Oral Health Department of the Navarre Health Service-Osasunbidea conducted a trial on 155 patients who underwent dental extractions and were receiving antiplatelet therapy. The patients were not requested to interrupt the medication and local measures were taken to control potential haemorrhage. Results: No major haemorrhages were reported. One patient had a moderate haemorrhage that required emergency care. In the remaining patients the bleeding was controlled with local measures. With regard to subsequent bleeding, no differences were observed between the various antiplatelet drugs used. The only statistically significant relationship found was between bleeding and the number of teeth extracted. Conclusions: It can be concluded that no more than 3 teeth should be removed at any one time, and for multiple extractions, the teeth should be adjacent to each other

    Ensayo clínico aleatorizado y controlado para valorar una intervención por una unidad de hospitalización domiciliaria en la reducción de reingresos y muerte en pacientes dados de alta del hospital tras un ingreso por insuficiencia cardiaca

    [Resumen] Introducción y objetivos. Evaluar la eficacia de una intervención de educación en pacientes con insuficiencia cardiaca (IC) realizada por hospitalización a domicilio. Métodos. Ensayo clínico aleatorizado y controlado. Se incluyó a 279 pacientes con diagnóstico clínico de IC dados de alta de un hospital terciario entre febrero de 2001 y junio de 2002. Se excluyó a los pacientes con demencias, enfermedad terminal no cardiológica o enfermedad pulmonar obstructiva crónica. La información recogida incluyó las causas de la descompensación. La intervención fue fundamentalmente de tipo educativo, en el domicilio del participante, y se extendió hasta 15 días después del alta. Se realizaron ajustes de tratamiento durante la primera semana cuando fue necesario. El objetivo principal fue determinar la incidencia acumulada de reingreso o muerte. Los objetivos secundarios fueron la incidencia de reingreso y la mortalidad, así como la utilización de los servicios de urgencia. Se llevó a cabo un seguimiento telefónico a los 3, 6 y 12 meses, y una revisión de las historias clínicas si era necesario. Asimismo, se valoró la utilización de servicios de urgencias los primeros 6 meses. Resultados. Al año, 62 pacientes de 137 (45,3%) ingresaron o murieron en el grupo de intervención, en comparación con 75 de 142 (52,8%) en el grupo control (p = 0,232; riesgo relativo [RR] = 0,86). En los pacientes que se descompensaron por incumplimiento terapéutico, 16 de 45 (35,6%) ingresaron o murieron en el grupo de intervención, en comparación con 34 de 56 (60,7%) en el grupo control (p = 0,016; RR = 0,59). Conclusiones. Esta intervención es factible pero, administrada de manera indiscriminada a todo paciente dado de alta por IC, en el mejor de los casos sólo podemos esperar un beneficio modesto, que en este estudio en particular no llegó a alcanzar significación estadística

    Altres ajuts: This study was supported by the funding from the Spanish Society of Cardiology.Elderly patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS) may present delirium but its clinical relevance is unknown. This study aimed at determining the clinical associated factors, and prognostic implications of delirium in old-aged patients admitted for NSTE-ACS. LONGEVO-SCA is a prospective multicenter registry including unselected patients with NSTE-ACS aged ≥ 80 years. Clinical variables and a complete geriatric evaluation were assessed during hospitalization. The association between delirium and 6-month mortality was assessed by a Cox regression model weighted for a propensity score including the potential confounding variables. We also analysed its association with 6-month bleeding and cognitive or functional decline. Among 527 patients included, thirty-seven (7%) patients presented delirium during the hospitalization. Delirium was more frequent in patients with dementia or depression and in those from nursing homes (27.0% vs. 3.1%, 24.3% vs. 11.6%, and 11.1% vs. 2.2%, respectively; all P < 0.05). Delirium was significantly associated with in-hospital infections (27.0% vs. 5.3%, P < 0.001) and usage of diuretics (70.3% vs. 49.8%, P = 0.02). Patients with delirium had longer hospitalizations [median 8.5 (5.5-14) vs. 6.0 (4.0-10) days, P = 0.02] and higher incidence of 6-month bleeding and mortality (32.3% vs. 10.0% and 24.3% vs. 10.8%, respectively; both P < 0.05) but similar cognitive or functional decline. Delirium was independently associated with 6-month mortality (HR = 1.47, 95% CI: 1.02-2.13, P = 0.04) and 6-month bleeding events (OR = 2.87; 95% CI: 1.98-4.16, P < 0.01). In-hospital delirium in elderly patients with NSTE-ACS is associated with some preventable risk factors and it is an independent predictor of 6-month mortality

    Sleep duration and napping in relation to colorectal and gastric cancer in the MCC-Spain study

    Sleep duration is a novel and potentially modifiable risk factor for cancer. We evaluated the association of self-reported sleep duration and daytime napping with odds of colorectal and gastric cancer. We included 2008 incident colorectal cancer cases, 542 gastric cancer cases and 3622 frequency-matched population controls, recruited in the MCC-Spain case-control study (2008-2013). Sleep information, socio-demographic and lifestyle characteristics were obtained through personal interviews. Multivariable adjusted logistic regression models were used to estimate odds ratios (OR) with 95% confidence intervals (CI) for cancer, across categories of sleep duration (? 5, 6, 7, 8, ? 9 hours/day), daytime napping frequency (naps/week) and duration (minutes/nap). Compared to 7 hours of sleep, long sleep was associated with increased odds of colorectal (OR?9 hours: 1.59; 95%CI 1.30-1.94) and gastric cancer (OR?9 hours: 1.95; 1.37-2.76); short sleep was associated with increased odds of gastric cancer (OR?5 hours: 1.32; 0.93-1.88). Frequent and long daytime naps increased the odds of colorectal (OR6-7 naps/week, ?30 min: 1.32; 1.14-1.54) and gastric cancer (OR6-7 naps/week, ?30 min: 1.56; 1.21-2.02). Effects of short sleep and frequent long naps were stronger among participants with night shift-work history. Sleep and circadian disruption may jointly play a role in the etiology of colorectal and gastric cancer.Funding: The study was funded by the “Accion Transversal del Cancer”, approved on the Spanish Ministry Council on 11 October 2007, by the Instituto de Salud Carlos III-FEDER (PI08/1770, PI08/0533, PI08/1359, PI09/00773-Cantabria, PI09/01286-León, PI09/01903-Valencia, PI09/02078-Huelva, PI09/01662-Granada, PI11/01403, PI11/01889-FEDER, PI11/00226, PI11/01810, PI11/02213, PI12/00488, PI12/00265, PI12/01270, PI12/00715, PI12/00150), by the Fundación Marqués de Valdecilla (API 10/09), by the ICGC International Cancer Genome Consortium CLL (The ICGC CLL-Genome Project is funded by Spanish Ministerio de Economía y Competitividad (MINECO) through the Instituto de Salud Carlos III (ISCIII) and Red Temática de Investigación del Cáncer (RTICC) del ISCIII (RD12/0036/0036)), by the Junta de Castilla y León (LE22A10-2), by the Consejería de Salud of the Junta de Andalucía (2009-S0143), by the Conselleria de Sanitat of the Generalitat Valenciana (AP_061/10), by the Recercaixa (2010ACUP 00310), by the European Commission grants FOOD-CT-2006-036224-HIWATE, by the Spanish Association Against Cancer (AECC) Scientific Foundation, by the Catalan Government DURSI grant 2009SGR1489.
