The Mousterian sequence from El Niño cave (Aýna, Albacete) and the Neanderthal occupation of south-eastern Iberia

Resumen: En este artículo se presentan los resultados de la revisión de los materiales arqueológicos procedentes de la excavación realizada en 1973 en la Cueva del Niño (Aýna, Albacete) correspondientes a ocupaciones del Paleolítico Medio. Esta revisión se realizó fundamentalmente mediante el análisis tecnológico de la industria lítica, el estudio arqueozoológico y tafonómico de los restos de macromamíferos y el análisis de los restos carpológicos. Además, se presentan las dataciones obtenidas para los niveles revisados. Estas dataciones sitúan la ocupación de la cavidad a finales del MIS3. A pesar del reducido número de restos arqueológicos disponibles,la información resultante permite situar el yacimiento de la Cueva del Niño en el contexto del final del Paleolítico Medio del sureste de la Península Ibérica, y aportar nuevos datos a la problemática de la desaparición de las últimas poblaciones neandertales.Abstract: This paper reviews the results obtained from the 1973 excavation of El Niño cave (Aýna, Albacete), corresponding to the Middle Palaeolithic occupations of the site. We present the technological analysis of lithic assemblages, the archaeozoological and taphonomical analysis of faunal remains, the analysis of plant macro remains, and the dates obtained for the archaeological levels. These dates place the Mousterian occupations of El Niño during MIS3. Despite the reduced number of archaeological remains, the results obtained permit the cave of El Niño cave to be placed within the context of Late Middle Palaeolithic in south-eastern Iberia, and provide new data regarding the process of extinction of the last Neanderthal populations

Multifunctional nanoassemblies target bacterial lipopolysaccharides for enhanced antimicrobial DNA delivery

The development of new therapeutic strategies against multidrug resistant Gram-negative bacteria is a major challenge for pharmaceutical research. In this respect, it is increasingly recognized that an efficient treatment for resistant bacterial infections should combine antimicrobial and anti-inflammatory effects. Here, we explore the multifunctional therapeutic potential of nanostructured self-assemblies from a cationic bolaamphiphile, which target bacterial lipopolysaccharides (LPSs) and associates with an anti-bacterial nucleic acid to form nanoplexes with therapeutic efficacy against Gram-negative bacteria. To understand the mechanistic details of these multifunctional antimicrobial-anti-inflammatory properties, we performed a fundamental study, comparing the interaction of these nanostructured therapeutics with synthetic biomimetic bacterial membranes and live bacterial cells. Combining a wide range of experimental techniques (Confocal Microscopy, Fluorescence Correlation Spectroscopy, Microfluidics, NMR, LPS binding assays), we demonstrate that the LPS targeting capacity of the bolaamphiphile self-assemblies, comparable to that exerted by Polymixin B, is a key feature of these nanoplexes and one that permits entry of therapeutic nucleic acids in Gram-negative bacteria. These findings enable a new approach to the design of efficient multifunctional therapeutics with combined antimicrobial and anti-inflammatory effects and have therefore the potential to broadly impact fundamental and applied research on self-assembled nano-sized antibacterials for antibiotic resistant infections

The Neolithic of El Niño cave (Ayna, Albacete) in the Sierra del Segura context

Resumen: Desde su excavación en el verano de 1973, la Cueva del Niño ha sido considerada un yacimiento de gran importancia para conocer el proceso de introducción de la economía de producción o de la tecnología cerámica en el sureste de la Península Ibérica, y especialmente para establecer cómo dicho proceso pudo haber afectado a las poblaciones ya asentadas en la región de la Sierra del Segura. Sin embargo, la información proporcionada por la Cueva del Niño resultaba muy fragmentaria, debido a la falta de un estudio de conjunto de las ocupaciones neolíticas del yacimiento. En este artículo, se presenta el análisis de las producciones cerámicas, la industria lítica y los restos de fauna, así como las dataciones existentes para los niveles holocenos del depósito. La revisión de las diversas evidencias proporcionadas por el yacimiento permite plantear que la Cueva del Niño habría actuado probablemente como una estación para el pastoreo y la caza, sirviendo como satélite de otros yacimientos de mayor entidad. No obstante, las limitaciones impuestas por el hecho de tratarse de una excavación efectuada hace cuarenta años impide aportar aspectos concluyentes sobre la dinámica del proceso de introducción del Neolítico en la Sierra del Segura.Abstract: Since its excavation in the summer of 1973, El Niño cave has been considered a key site to understand the process of production economy and pottery technology introduction in South-eastern Iberian Peninsula, and especially to approach how such process could have affected people already settled in the Segura mountains. However, data from El Niño cave was very fragmentary, due to the lack of a broad study of Neolithic occupations of the site. In this paper, we present the analysis of pottery, lithic industry and faunal remains, as well as the existing dates from the site´s Holocene levels. The review of different evidence from the site allows suggesting that El Niño cave would have probably acted as a hunting and shepherding station, being a logistical site of larger places. However, limitations due to the fact that we are dealing with a 40- year-old excavation, prevent specifying how the process of Neolithic introduction in the Segura Mountains occurred

Role of age and comorbidities in mortality of patients with infective endocarditis

[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Process for planning and control of software projects using XedroGESPRO

The software project management in Cuba has become a key area for improving production processes and decisionmaking in organizations. Several models and standards for process improvement, related with project management, proposed best practices on issues of planning and control of projects. However, they are generic guidelines that describe only those activities to execute, leaving the responsibility for implementing to organizations, using sometimes , expensive proprietary informatics tools to achieve these goals. This research proposes a process for planning and control of software projects using Xedro-GESPRO: an open-source software tool for project management domestically implemented. The proposal is successfully being applied by the network of production centers of the Informatic Sciences University of Cuba, observing greater efficiency and effectiveness in the planning and control of their projects
