Cutting down on the grog: the crystallisation of Neolithic ceramic traditions at Cova dâEn Pardo (Alicante, Spain) and cultural change in the western Mediterranean basin (mid-6th and 5th millennia cal. BC)
This paper presents the characterisation of 48 ceramic samples from Cova dâEn Pardo (Alicante, Spain). Provenance and technology analysis are carried out on materials dated back to different Early and Middle Neolithic cultural phases, including pioneer and Epicardial levels, poorly known in the area. The techniques employed are optical petrography and scanning electron microscope. Two main fabrics were identified, characterised by the heavy presence of temper (grog and calcite), along with five minor petrographic classes, including two imports, one of them probably from southern Iberia. The comparison among occupational phases within the site reveals changes along the stratigraphic series, especially during the transition from the 6th to 5th millennia cal. BC, which is reflected in temper choice. Evidence from the earliest occupation of the site also agrees with the picture of discontinuity previously observed on nearby contexts between pioneer and traditional Cardial ceramic technology, which might be connected to neolithization routes. Firing technology is characterised by the occurrence of microstructure gradients and signs of fast heating rates.Sample preparation and analyses were funded by the projects NEOMEDPOT (Marie SkĆodowska-Curie program, European Commission, grant number 659466) and Espacios sociales y espacios de frontera durante el calcolĂtico y la Edad del Bronce en el Levante de la penĂnsula IbĂ©rica (HAR2016-76586-P, Ministerio de EconomĂa y Competitividad and FEDER).

Cova dâEn Pardo (Planes, Alicante). Un avance sobre la secuencia cultural
La valoraciĂłn general de las recientes excavaciones en la Cova dâEn Pardo (1993 â2006) permiten presentar la secuencia de ocupaciĂłn de la cavidad, en lo que la Prehistoria reciente se refiere, desde un NeolĂtico caracterizado por la presencia de cerĂĄmicas impresas hasta el Bronce Final. Se adelanta ahora la revisiĂłn de la sedimentologĂa, nuevas dataciones de radiocarbono y la valoraciĂłn cultural de los distintos niveles a partir de la valoraciĂłn de la cerĂĄmica localizada en las intervenciones de la denominada sala de la derecha.The valuation in general of the recent excavations at the En Pardoâs Cave (1993-2006) presents the sequence of the cavity occupation, as it recent Prehistory refers to, from a Neolithic which characterizes for the presence of printed ceramics to the Final Bronze. It implies to go further with the review of the sedimentology, new radiocarbon data and the cultural evaluation of the different levels obtained from the valuation of the ceramic found during the interventions done at the so-called gallery of the right

Red en cultura material prehistĂłrica: talleres de experimentaciĂłn lĂtica en titulaciones de la UA
Una parte muy importante de las herramientas que fueron elaborando los seres humanos a lo largo de mĂĄs de 2,5 millones de años se fabricaron durante la Prehistoria usando diferentes tipos de rocas. Entre los contenidos curriculares de los grados en Historia en España y en mĂĄsteres afines, destacan diversas nociones sobre tecnologĂa e instrumental lĂtico prehistĂłrico, para que el alumnado conozca los procesos de producciĂłn lĂtica tallada, su evoluciĂłn tecnolĂłgica y tipolĂłgica, y los procesos de clasificaciĂłn y anĂĄlisis. A pesar del creciente empleo de material grĂĄfico como recurso docente, la metodologĂa de clase teĂłrica/participativa se muestra insuficiente a la hora de conseguir buenos resultados de aprendizaje. El desarrollo de talleres de experimentaciĂłn lĂtica tallada sobre instrumental prehistĂłrico permite el aprendizaje mediante la interacciĂłn y una mejor asimilaciĂłn por parte de los estudiantes. La experiencia de las asignaturas del Grado en Historia y del MĂĄster en ArqueologĂa Profesional y GestiĂłn del Patrimonio de la UA es un ejemplo de evaluaciĂłn de las fortalezas y debilidades del desarrollo de dichos talleres
History Shaped the Geographic Distribution of Genomic Admixture on the Island of Puerto Rico
Contemporary genetic variation among Latin Americans human groups reflects population migrations shaped by complex historical, social and economic factors. Consequently, admixture patterns may vary by geographic regions ranging from countries to neighborhoods. We examined the geographic variation of admixture across the island of Puerto Rico and the degree to which it could be explained by historic and social events. We analyzed a census-based sample of 642 Puerto Rican individuals that were genotyped for 93 ancestry informative markers (AIMs) to estimate African, European and Native American ancestry. Socioeconomic status (SES) data and geographic location were obtained for each individual. There was significant geographic variation of ancestry across the island. In particular, African ancestry demonstrated a decreasing East to West gradient that was partially explained by historical factors linked to the colonial sugar plantation system. SES also demonstrated a parallel decreasing cline from East to West. However, at a local level, SES and African ancestry were negatively correlated. European ancestry was strongly negatively correlated with African ancestry and therefore showed patterns complementary to African ancestry. By contrast, Native American ancestry showed little variation across the island and across individuals and appears to have played little social role historically. The observed geographic distributions of SES and genetic variation relate to historical social events and mating patterns, and have substantial implications for the design of studies in the recently admixed Puerto Rican population. More generally, our results demonstrate the importance of incorporating social and geographic data with genetics when studying contemporary admixed populations

Association Between Preexisting Versus Newly Identified Atrial Fibrillation and Outcomes of Patients With Acute Pulmonary Embolism
Background Atrial fibrillation (AF) may exist before or occur early in the course of pulmonary embolism (PE). We determined the PE outcomes based on the presence and timing of AF. Methods and Results Using the data from a multicenter PE registry, we identified 3 groups: (1) those with preexisting AF, (2) patients with new AF within 2 days from acute PE (incident AF), and (3) patients without AF. We assessed the 90-day and 1-year risk of mortality and stroke in patients with AF, compared with those without AF (reference group). Among 16 497 patients with PE, 792 had preexisting AF. These patients had increased odds of 90-day all-cause (odds ratio [OR], 2.81; 95% CI, 2.33-3.38) and PE-related mortality (OR, 2.38; 95% CI, 1.37-4.14) and increased 1-year hazard for ischemic stroke (hazard ratio, 5.48; 95% CI, 3.10-9.69) compared with those without AF. After multivariable adjustment, preexisting AF was associated with significantly increased odds of all-cause mortality (OR, 1.91; 95% CI, 1.57-2.32) but not PE-related mortality (OR, 1.50; 95% CI, 0.85-2.66). Among 16 497 patients with PE, 445 developed new incident AF within 2 days of acute PE. Incident AF was associated with increased odds of 90-day all-cause (OR, 2.28; 95% CI, 1.75-2.97) and PE-related (OR, 3.64; 95% CI, 2.01-6.59) mortality but not stroke. Findings were similar in multivariable analyses. Conclusions In patients with acute symptomatic PE, both preexisting AF and incident AF predict adverse clinical outcomes. The type of adverse outcomes may differ depending on the timing of AF onset.info:eu-repo/semantics/publishedVersio
Effectiveness of an intervention for improving drug prescription in primary care patients with multimorbidity and polypharmacy:Study protocol of a cluster randomized clinical trial (Multi-PAP project)
This study was funded by the Fondo de Investigaciones Sanitarias ISCIII (Grant Numbers PI15/00276, PI15/00572, PI15/00996), REDISSEC (Project Numbers RD12/0001/0012, RD16/0001/0005), and the European Regional Development Fund ("A way to build Europe").Background: Multimorbidity is associated with negative effects both on people's health and on healthcare systems. A key problem linked to multimorbidity is polypharmacy, which in turn is associated with increased risk of partly preventable adverse effects, including mortality. The Ariadne principles describe a model of care based on a thorough assessment of diseases, treatments (and potential interactions), clinical status, context and preferences of patients with multimorbidity, with the aim of prioritizing and sharing realistic treatment goals that guide an individualized management. The aim of this study is to evaluate the effectiveness of a complex intervention that implements the Ariadne principles in a population of young-old patients with multimorbidity and polypharmacy. The intervention seeks to improve the appropriateness of prescribing in primary care (PC), as measured by the medication appropriateness index (MAI) score at 6 and 12months, as compared with usual care. Methods/Design: Design:pragmatic cluster randomized clinical trial. Unit of randomization: family physician (FP). Unit of analysis: patient. Scope: PC health centres in three autonomous communities: Aragon, Madrid, and Andalusia (Spain). Population: patients aged 65-74years with multimorbidity (â„3 chronic diseases) and polypharmacy (â„5 drugs prescribed in â„3months). Sample size: n=400 (200 per study arm). Intervention: complex intervention based on the implementation of the Ariadne principles with two components: (1) FP training and (2) FP-patient interview. Outcomes: MAI score, health services use, quality of life (Euroqol 5D-5L), pharmacotherapy and adherence to treatment (Morisky-Green, Haynes-Sackett), and clinical and socio-demographic variables. Statistical analysis: primary outcome is the difference in MAI score between T0 and T1 and corresponding 95% confidence interval. Adjustment for confounding factors will be performed by multilevel analysis. All analyses will be carried out in accordance with the intention-to-treat principle. Discussion: It is essential to provide evidence concerning interventions on PC patients with polypharmacy and multimorbidity, conducted in the context of routine clinical practice, and involving young-old patients with significant potential for preventing negative health outcomes.
