    The rocks from Corumbataí Formation, successfully used by the floor tiles industries of the Ceramic Cluster of Santa Gertrudes (SP, Brazil). This cluster is located in the region of the cities of Santa Gertrudes, Rio Claro, Cordeirópolis, Limeira and Araras. Geologically, the rocks may be classified into five ceramic lithofacies, as follows: massive, laminated, intercalated I, intercalated II and altered. Chemically, they are considered as clays with medium amount of fluxing agents, and their composition of Na2O+K2O ranges from 2.9% in the altered lithofacies up to 4.31% in the intercalated I lithofacies .The main clay minerals are illite and kaolinite (both always present), but montmorillonite often occurs in the intercalated I and II, and in the laminated lithofacies. The other main minerals are quartz, albite-type feldspar and calcite. Based on the ceramic characterization the lithofacies are classified, according to the Floor Tiles Classification, within the group BIIb (BII stands for mechanical resistance ranging from 180 to 300 Kgf/cm2, and b stands for water absorption ranging from 6 to 10 %), except for some intercalated I and II and altered lithofacies samples, which presented water absorption values above 10%.A Formação Corumbataí é atualmente utilizada com sucesso pela indústria de revestimento cerâmico no pólo de cerâmica de Santa Gertrudes. Este engloba os municípios de Santa Gertrudes, Rio Claro, Cordeirópolis, Limeira, Piracicaba e Araras. De acordo com os estudos geológicos realizados, as argilas da Formação Corumbataí foram divididas em cinco litofácies cerâmicas, sendo elas: maciça, laminada, intercalada I, intercalada II e alterada. De acordo com suas características químicas, são consideradas como argilas com teores médios de elementos fundentes, com os valores da soma dos óxidos alcalinos (Na2O + K2O) variando de 2,9% na litofácies alterada até valores de 4,3% na litofácies intercalada I. Os argilominerais predominantes são a illita e a caulinita (presentes em todas as litofácies), além da montmorillonita que ocorre com freqüência nas litofácies intercalada I e II e laminada. Outros minerais importantes são: quartzo, feldspato do tipo albita, hematita e calcita. Os resultados cerâmicos possibilitaram enquadrar as litofácies cerâmicas dentro do Grupo BIIb na Classificação de Revestimentos Cerâmicos (BII – valores de resistência à flexão da ordem de 180-300 Kgf/cm2; b – valores de absorção de água (Abs) de 6 a 10%), porém, alguns valores de Abs ficaram acima de 10% nas litofácies intercalada I, intercalada II e na alterada

    A Formação Corumbataí na região de Rio Claro é representada predominantemente por siltitos argilosos com intercalações de siltitos arenosos, constituídos por illita, quartzo, feldspatos, carbonatos, hematita, montmorillonita, clorita e zeólita, de origem autígena e/ou detrítica. As variações texturais, e principalmente mineralógicas ao longo do empilhamento dos sedimentos da Formação Corumbataí, permitem dividi-la, nesta região, em cinco níveis mineralógico-texturais propostos nesse trabalho. As relações texturais e morfológicas entre componentes detríticos e autígenos sugerem transporte em ambiente árido, com área fonte de topografia suave, sem forte influência fluvial, gerando sedimentos que foram acumulados em um extenso mar epicontinental raso, com indícios de exposições aéreas já nos estratos basais, e com possível ligação com o oceano. Também evidencia que a espessura da lâmina d’água diminuiu progressivamente para o topo da sequência, ocorrendo oscilações em função da influência de marés e/ou tempestades. A composição mineralógica, em associação com a textura, evidencia que a Formação Corumbataí foi submetida a efeito termal após a litificação, promovendo transformações mineralógicas, hidrotermalismo e formação de brechas hidráulicas, provocadas pelo magmatismo básico que deu origem à Formação Serra Geral

    A Formação Corumbataí na região de Rio Claro - Limeira - Araras é representada por uma sucessão de siltitos, constituídos principalmente por filossilicatos (predominando illita, embora também ocorram montmorillonita, biotita, clorita, caulinita e interestratificados regulares e irregulares, quartzo, plagioclásios e feldspatos potássicos, carbonatos, hematita, goethita e zeólitas, de origem autígena e/ou detrítica. Quimicamente as rochas da Formação Corumbataí são classificadas principalmente como wackes e secundariamente como folhelhos, cuja principal fonte são rochas ígneas félsicas e/ou rochas sedimentares quartzosas. A aplicação de índices de maturidade química nas rochas analisadas sugere que estas são quimicamente imaturas e que a fonte foi submetida a condições de intemperismo moderado. Diagramas discriminantes para ambientes tectônicos sugerem que a fonte dos sedimentos da Formação Corumbataí são rochas quimicamente semelhantes a rochas formadas em margem ativa e/ou arcos de ilha, embora depositados em outro contexto geotectônico (bacia intracratônica)

    ArticleLa enfermedad de Gaucher (EG), debe su nombre por haber sido descrita por Phillipe Gaucher en 1882. Es la enfermedad más frecuente del grupo de las enfermedades de depósito lisosomal comprendidas dentro de los errores innatos del metabolismo (1). La enfermedad de Gaucher se debe a mutaciones en el gen responsable de la síntesis de la enzima lisosomal b-glucocerebrosidasa ácida, también llamada ß-Glucosidasa ácida, (o ß-GA), cuyos locus se ubica en 1q21, es decir en la banda uno de la región 2 del brazo largo del cromosoma 1. El patrón de herencia es autosómico recesivo, es decir que la mutación en éste gen debe darse en estado de homocigocia (2)

    Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

    Get PDF
    BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

    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)

    Get PDF
    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 (≥3 chronic diseases) and polypharmacy (≥5 drugs prescribed in ≥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.
