    Purpose: To analyze the influence of the pecking motion frequency on the cyclic fatigue resistance of endodontic rotary files. Material and Methods: Sixty PlexV 25.06 endodontic rotary files were selected and distributed into three groups: 30 movements/min (n = 20), 60 movements/min (n = 20), and 120 movements/min (n = 20). A dynamic cyclic fatigue device was designed using Computer Aided Design/ Computer Aided Engineering (CAD/CAE) technology and manufactured by 3D impressions to simulate the pecking motion performed by an operator. Failures of the endodontic rotary files were detected by a Light-Emitting Diode (LED)/Light-Dependent Resistor (LDR) system controlled by an Arduino-Driver complex and management software. Endodontic rotary files were tested on an artificial root canal manufactured by wire electrical discharge machining (EDM), with similar dimensions to those of the instrument under examination. Endodontic rotary files were used following the manufacturer's recommendations. The results were analyzed by ANOVA and Weibull statistics. Results: All pairwise comparisons revealed statistically significant differences in all three variables, except for the difference in the number of cycles between the groups with 60 and 120 movements/min (p = 0.298). The scale distribution parameter of Weibull statistics showed statistically significant differences in all three variables, except for the differences in the number of cycles between groups with 30 and 60 movements/min (p = 0.0722). No statistically significant differences in the three variables were observed for the shape distribution parameter. Conclusion: A low frequency of pecking motion is recommended to reduce the risk of failure of endodontic rotary files associated with cyclic fatigue

    [SPA] Debido al desgaste de los suelos por el uso indiscriminado de pesticidas y herbicidas, la búsqueda de alternativas a la agricultura convencional ha ido ganando interés alrededor del mundo. En este sentido, los microorganismos son importantes, ya que están incluidos en muchas funciones indispensables en los suelos, como la fijación de nitrógeno. En este trabajo se estudiaron 3 tipos de agricultura diferentes i) convencional, ii) ecológica con estiércol y iii) ecológica con compost, con el objetivo de estudiar los cambios ocurridos en las comunidades bacterianas, así como su funcionalidad, las parcelas estaban ubicadas en Cartagena (España). Para estudiar estas funciones, se utilizó el gen 16S obtenido a través de la secuenciación masiva y seguidamente se realizaron aproximaciones matemáticas a través de PICRUSt para predecir la función de esos microorganismos en el suelo. Por otro lado, se realizó un análisis de redes ecológicas moleculares (MENA) para estudiar las interacciones entre esas bacterias. Los resultados de esta investigación mostraron como el compost puede incrementar algunas rutas metabólicas y puede influir en la organización bacteriana, favoreciendo la modulación y las conexiones entre los nodos. [ENG] Due to soil degradation caused by indiscriminate use of pesticides and herbicides, search for sustainable alternatives to conventional agriculture has taken interest around the world. In this sense, microorganisms are important since they are involved in many indispensable functions on soils such a nitrogen fixation. In this work, three different cropping systems were studied i) conventional ii) organic with manure and iii) organic with compost, with the aim to study changes occurred on bacterial communities as well as their functionality. Experimental plots were located in Cartagena (Spain). To study these functions, 16S gen obtain through high-throughput then a mathematical approximations using PICRUST algorithm were used to predict functionality on soils. On the other hand, a molecular ecological network analysis (MENA) was made to study the interactions among these bacteria. Results of this research showed how compost can enhance some metabolic pathways and can influence the bacterial organization favoring modulation and connections among nodes.Este proyecto está financiado por la Unión Europea a través del proyecto del Programa Horizonte 2020 Diverfarming (GA 728003)

    Background Non-invasive ventilation (NIV) is an effective form of treatment in patients with obesity hypoventilation syndrome (OHS) who have concomitant severe obstructive sleep apnoea (OSA). However, there is a paucity of evidence on the efficacy of NIV in patients with OHS without severe OSA. We performed a multicentre randomised clinical trial to determine the comparative efficacy of NIV versus lifestyle modification (control group) using daytime arterial carbon dioxide tension (PaCO2) as the main outcome measure. Methods Between May 2009 and December 2014 we sequentially screened patients with OHS without severe OSA. Participants were randomised to NIV versus lifestyle modification and were followed for 2 months. Arterial blood gas parameters, clinical symptoms, health-related quality of life assessments, polysomnography, spirometry, 6-min walk distance test, blood pressure measurements and healthcare resource utilisation were evaluated. Statistical analysis was performed using intention-to-treat analysis. Results A total of 365 patients were screened of whom 58 were excluded. Severe OSA was present in 221 and the remaining 86 patients without severe OSA were randomised. NIV led to a significantly larger improvement in PaCO2 of -6 (95% CI -7.7 to -4.2) mm Hg versus -2.8 (95% CI -4.3 to -1.3) mm Hg, (p<0.001) and serum bicarbonate of -3.4 (95% CI -4.5 to -2.3) versus -1 (95% CI -1.7 to -0.2 95% CI) mmol/L (p<0.001). PaCO2 change adjusted for NIV compliance did not further improve the inter-group statistical significance. Sleepiness, some health-related quality of life assessments and polysomnographic parameters improved significantly more with NIV than with lifestyle modification. Additionally, there was a tendency towards lower healthcare resource utilisation in the NIV group. Conclusions NIV is more effective than lifestyle modification in improving daytime PaCO2, sleepiness and polysomnographic parameters. Long-term prospective studies are necessary to determine whether NIV reduces healthcare resource utilisation, cardiovascular events and mortality

    Importance: The Enhanced Recovery After Surgery (ERAS) care protocol has been shown to improve outcomes compared with traditional care in certain types of surgery. Objective: To assess the association of use of the ERAS protocols with complications in patients undergoing elective total hip arthroplasty (THA) and total knee arthroplasty (TKA). Design, Setting, and Participants: This multicenter, prospective cohort study included patients recruited from 131 centers in Spain from October 22 through December 22, 2018. All consecutive adults scheduled for elective THA or TKA were eligible for inclusion. Patients were stratified between those treated in a self-designated ERAS center (ERAS group) and those treated in a non-ERAS center (non-ERAS group). Data were analyzed from June 15 through September 15, 2019. Exposures: Total hip or knee arthroplasty and perioperative management. Sixteen individual ERAS items were assessed in all included patients, whether they were treated at a center that was part of an established ERAS protocol or not. Main Outcomes and Measures: The primary outcome was postoperative complications within 30 days after surgery. Secondary outcomes included length of stay and mortality. Results: During the 2-month recruitment period, 6146 patients were included (3580 women [58.2%]; median age, 71 [interquartile range (IQR), 63-76] years). Of these, 680 patients (11.1%) presented with postoperative complications. No differences were found in the number of patients with overall postoperative complications between ERAS and non-ERAS groups (163 [10.2%] vs 517 [11.4%]; odds ratio [OR], 0.89; 95% CI, 0.74-1.07; P =.22). Fewer patients in the ERAS group had moderate to severe complications (73 [4.6%] vs 279 [6.1%]; OR, 0.74; 95% CI, 0.56-0.96; P =.02). The median overall adherence rate with the ERAS protocol was 50.0% (IQR, 43.8%-62.5%), with the rate for ERAS facilities being 68.8% (IQR, 56.2%-81.2%) vs 50.0% (IQR, 37.5%-56.2%) at non-ERAS centers (P <.001). Among the patients with the highest and lowest quartiles of adherence to ERAS components, the patients with the highest adherence had fewer overall postoperative complications (144 [10.6%] vs 270 [13.0%]; OR, 0.80; 95% CI, 0.64-0.99; P <.001) and moderate to severe postoperative complications (59 [4.4%] vs 143 [6.9%]; OR, 0.62; 95% CI, 0.45-0.84; P <.001) and shorter median length of hospital stay (4 [IQR, 3-5] vs 5 [IQR, 4-6] days; OR, 0.97; 95% CI, 0.96-0.99; P <.001). Conclusions and Relevance: An increase in adherence to the ERAS program was associated with a decrease in postoperative complications, although only a few ERAS items were individually associated with improved outcomes

    Altres ajuts: Spanish AIDS Research Network; European Funding for Regional Development (FEDER).Objectives: We assessed the prevalence of anti-hepatitis C virus (HCV) antibodies and active HCV infection (HCV-RNA-positive) in people living with HIV (PLWH) in Spain in 2019 and compared the results with those of four similar studies performed during 2015-2018. Methods: The study was performed in 41 centres. Sample size was estimated for an accuracy of 1%. Patients were selected by random sampling with proportional allocation. Results: The reference population comprised 41 973 PLWH, and the sample size was 1325. HCV serostatus was known in 1316 PLWH (99.3%), of whom 376 (28.6%) were HCV antibody (Ab)-positive (78.7% were prior injection drug users); 29 were HCV-RNA-positive (2.2%). Of the 29 HCV-RNA-positive PLWH, infection was chronic in 24, it was acute/recent in one, and it was of unknown duration in four. Cirrhosis was present in 71 (5.4%) PLWH overall, three (10.3%) HCV-RNA-positive patients and 68 (23.4%) of those who cleared HCV after anti-HCV therapy (p = 0.04). The prevalence of anti-HCV antibodies decreased steadily from 37.7% in 2015 to 28.6% in 2019 (p < 0.001); the prevalence of active HCV infection decreased from 22.1% in 2015 to 2.2% in 2019 (p < 0.001). Uptake of anti-HCV treatment increased from 53.9% in 2015 to 95.0% in 2019 (p < 0.001). Conclusions: In Spain, the prevalence of active HCV infection among PLWH at the end of 2019 was 2.2%, i.e. 90.0% lower than in 2015. Increased exposure to DAAs was probably the main reason for this sharp reduction. Despite the high coverage of treatment with direct-acting antiviral agents, HCV-related cirrhosis remains significant in this population

    Political Iconography and Emotions in Electoral Campaigns: A Communicative Approach

    Get PDF
    The authors of this work believe that the fact that political iconography can influence reality and intervene in actual events -sometimes by using reinvented motifs and visual narratives from previous iconographic sources, after Warburg’s Pathosformel fashion–, is of utmost importance in political campaigns. In modern electoral campaigns, the use of visual themes that represent different emotions constitutes a clear link with the use of pathos in current political communication. From the perspective of political communication, this work analyses the use of iconography in modern electoral campaigns. In doing so, we trace a link between Warburg’s concept of the pathos formula and the use of different motifs of pathos developed in modern electoral campaigns. Electoral communication uses images linked to emotions such as enthusiasm, hope, fear and identity, which in this paper are studied from a database of posters and electoral spots from recent Spanish campaigns. The study also makes reference to visual motifs of pathos aimed at activating these emotions in the voters in different comparative campaigns and in electoral propaganda
