Cultivos da Idade do Ferro no Crasto de Palheiros: novos dados carpológicos da Plataforma Inferior Leste

Crasto de Palheiros tem sido alvo de diferentes estudos interdisciplinares que, desde o início incluíram análises de arqueobotânica. Neste âmbito, os estudos carpológicos permitiram a identificação de uma área de armazenagem na Plataforma Inferior Leste deste povoado, que terá sido destruída por um incêndio no final da Idade do Ferro. Restavam, porém, amostras por estudar que tinham o potencial de acrescentar dados relevantes para a compreensão deste local nesta cronologia.Foram estudados contextos numa área limítrofe à zona de armazenagem anteriormente identificada, tendo sido identificados cereais e leguminosas. Verificou-se um predomínio de trigos vestidos (Triticum dicoccum/spelta), identificando-se igualmente cevada (Hordeum vulgare) e trigos nus (Triticum aestivum/turgidum/durum). Outras espécies surgem de forma vestigial, tais como a fava (Vicia faba), milho-miúdo (Panicum miliaceum) e uva (Vitis vinífera), assim como diferentes espécies silvestres das quais destacamos os medronhos (Arbutus unedo).A escassez de material recuperado e a configuração do local sugere que este correspondia a uma área de acesso às estruturas de armazenagem e que estas eventualmente se prolongariam ligeiramente para a área aqui estudada.Interdisciplinary studies have been carried out at Crasto de Palheiros and these included archaeobotanical analyses. Previous carpological studies led to the identification in the Lower Eastern Platform of this settlement of a storage area that was destroyed in the end of the Iron Age. However, several samples remained unstudied and these had the potential to add data which could be important for the understanding of the platform in that chronology.The contexts studied were adjacent to the previously identified storage area and showed the presence of cereals and pulses. Hulled wheat (Triticum dicoccum/spelta) was predominant but hulled barley (Hordeum vulgare) and naked wheat (Triticum aestivum/durum/turgidum) were also identified. Remains from other species were rare and included faba bean (Vicia faba), broomcorn millet (Panicum miliaceum) and grapes (Vitis vinifera), as well as different wild species of which fruits from strawberry trees (Arbutus unedo) were the most abundant.The scarcity of carpological remains that were recovered, together with the configuration of the place suggest this to have been an access area to the storage structures. These storage facilities might have only slightly extended to the area studied here

Improving resource efficiency and minimize environmental footprint: a case study preliminary results

Panasqueira Mine (Portugal) has been mainly exploited for wolframite, cassiterite and chalcopyrite (W, Sn, Cu). Through the detailed and careful characterization of tailings with different mineralogy, new invaluable insights into the weathering characteristics of many different minerals will be received, making possible proper risk assessments, and predict which type of tailings might pose severe future environmental risk namely to the Zêzere river. The Zêzere River is an important river and is under the Cabeço do Pião tailings influence. The knowledge and methods acquired will lead to a conceptual model working as guidance to a more sustainable mining in the hereafter.This work of the project Remine was funded with public national funds from FCT under the programme for International Cooperation ERA-NET, supported by ERA-MIN (2011-2015) funded under the EU 7th Framework Programme FP7-NMP having also for partners the Technical University of Luleå (Sweden) and the National Institute for Metals and Radioactive Resources (INCDMRR), Romania.info:eu-repo/semantics/publishedVersio

Investigating the role of symptom valorisation in tuberculosis patient delay in urban areas in Portugal

URBANTB group: Patrícia Soares (Representative of the consortium), Mário Carreira, Sofia Pereira, Catarina Alves, Filipe Alves, Ana Rodrigues, Ana Moreira, Márcia Cardoso, Sandra Mota, Ana Gomes, Liliana Ferreira, Marta Lopes, Isabel Correia, Juan Rachadell, Maria Gameiro, Ângela Dias, Manuel Pereira, Jorge Gonçalves, Maria Gonçalves, Adriana Taveira, Celene Neves, Lucinda Silva, Maria Mendes, Maria Teixeira, Maria Pereira, Milena Piedade, Antónia Teixeira & Carlos Carvalho.Background: Diagnosis delay contributes to increased tuberculosis (TB) transmission and morbimortality. TB incidence has been decreasing in Portugal, but median patient delay (PD) has risen. Symptom valorisation may determine PD by influencing help-seeking behaviour. We aimed to analyse the association between symptom valorisation and PD, while characterising individuals who disregarded their symptoms. Methods: A cross-sectional study was conducted among TB patients in Lisbon and Oporto in 2019 - 2021. Subjects who delayed seeking care because they did not value their symptoms or thought these would go away on their own were considered to have disregarded their symptoms. PD was categorised using a 21-day cut-off, and a 30-day cut-off for sensitivity analysis. We estimated the effect of symptom valorisation on PD through a directed acyclic graph. Then, a multivariable regression analysis characterised patients that disregarded their symptoms, adjusting for relevant variables. We fitted Poisson regression models to estimate crude and adjusted prevalence ratios (PR). Results: The study included 75 patients. Median PD was 25 days (IQR 11.5-63.5), and 56.0% of participants had PD exceeding 21 days. Symptom disregard was reported by 38.7% of patients. Patients who did not value their symptoms had higher prevalence of PD exceeding 21 days compared to those who valued their symptoms [PR 1.59 (95% CI 1.05-2.42)]. The sensitivity analysis showed consistent point estimates but wider confidence intervals [PR 1.39 (95% CI 0.77-2.55)]. Being a smoker was a risk factor for symptom disregard [PR 2.35 (95% CI 1.14-4.82)], while living in Oporto [PR 0.35 (95% CI 0.16-0.75)] and having higher household incomes [PR 0.39 (95% CI 0.17-0.94)] were protective factors. Conclusions: These findings emphasise the importance of symptom valorisation in timely TB diagnosis. Patients who did not value their symptoms had longer PD, indicating a need for interventions to improve symptom recognition. Our findings also corroborate the importance of the socioeconomic determinants of health, highlighting tobacco as a risk factor both for TB and for PD.This work was supported by the Fundação para a Ciência e Tecnologia (FCT, Portugal) [Grant: PTDC/SAU-PUB/31346/2017].

SARS-CoV-2 introductions and early dynamics of the epidemic in Portugal

Genomic surveillance of SARS-CoV-2 in Portugal was rapidly implemented by the National Institute of Health in the early stages of the COVID-19 epidemic, in collaboration with more than 50 laboratories distributed nationwide. Methods By applying recent phylodynamic models that allow integration of individual-based travel history, we reconstructed and characterized the spatio-temporal dynamics of SARSCoV-2 introductions and early dissemination in Portugal. Results We detected at least 277 independent SARS-CoV-2 introductions, mostly from European countries (namely the United Kingdom, Spain, France, Italy, and Switzerland), which were consistent with the countries with the highest connectivity with Portugal. Although most introductions were estimated to have occurred during early March 2020, it is likely that SARS-CoV-2 was silently circulating in Portugal throughout February, before the first cases were confirmed. Conclusions Here we conclude that the earlier implementation of measures could have minimized the number of introductions and subsequent virus expansion in Portugal. This study lays the foundation for genomic epidemiology of SARS-CoV-2 in Portugal, and highlights the need for systematic and geographically-representative genomic surveillance.We gratefully acknowledge to Sara Hill and Nuno Faria (University of Oxford) and Joshua Quick and Nick Loman (University of Birmingham) for kindly providing us with the initial sets of Artic Network primers for NGS; Rafael Mamede (MRamirez team, IMM, Lisbon) for developing and sharing a bioinformatics script for sequence curation (https://github.com/rfm-targa/BioinfUtils); Philippe Lemey (KU Leuven) for providing guidance on the implementation of the phylodynamic models; Joshua L.

Estudo Paleoetnobotânico do Crasto de Palheiros na Idade do Ferro - uma análise carpológica

Através da análise carpológica da Área Habitacional 6 do Crasto de Palheiros procuramos contribuir para a compreensão da organização crono‑espacial e funcional do Recinto L da Plataforma Inferior Leste, tentando expandir o conhecimento sobre estratégias de armazenamento, processamento e consumo identificadas, com base na identificação taxonómica e na comparação com resultados anteriores. Em quantidades extremamente reduzidas regista‑se uma presença de cereais – trigos vestidos (Triticum dicoccum e Triticum spelta), cevadas (Hordeum) e frutos de Arbutus unedo. É ainda de realçar a identificação de uvas (Vitis vinífera).Through carpological analysis of the Dwelling Area 6 of Crasto de Palheiros, we aim to contribute to the understanding of the chrono-spatial and functional organization of the Enclosure L at Lower Eastern Platform, in an attempt to expand the knowledge of storage, processing and consumption strategies, based on taxonomic identification and comparison to previous results. In small quantities there is a presence of cereals – hulled wheats (Triticum dicoccum and Triticum spelta), barley (Hordeum) and fruits of Arbutus unedo. There are also grapes (Vitis vinifera).info:eu-repo/semantics/publishedVersio
