Purpose. To analyze prosthetic complications of single screw-retained implant-supported metal–ceramic fixed prostheses (SSIMCFPs). Materials and Methods. A total of 457 medical records of patients treated with implants at the University Dental Clinic of the European University of Valencia from 2016 to 2022 were reviewed. Of the 335 SSIMCFPs evaluated, 222 were included. The following data were collected from medical records: age, sex, prosthesis location, implant diameter, type of antagonist, date of prosthesis placement, type of prosthetic complications, and the date of the occurrence of complications. Statistical analysis was estimated at the patient level with a simple binary logistic regression and at the prosthesis level, a simple logistic regression with generalized estimating equation models (p

In October 2020, we conducted a population-based prospective cohort study to determine post-COVID-19 complications, recovery, return to usual health, and associated risk factors in 536 cases of COVID-19 outbreak in Borriana (Spain) by administering an epidemiological questionnaire via phone interviews. A total of 484 patients participated (90.3%), age mean 37.2 ± 17.1 years, and 301 females (62.2%). Mild illness was the most common COVID-19 manifestation. After six months, 160 patients (33.1%) suffered at least one complication post-COVID-19, and 47 (29.4%) of them sought medical assistance. The most frequent persistent symptoms were hair loss, fatigue, loss of smell or taste, and headache. Risk factors associated with a complication were female sex (adjusted relative risk, [aRR] = 1.93 95% confidence interval [CI] 1.41–2.65), age 35 years and above (aRR = 1.50 95% CI 1.14–1.99), B blood group (aRR = 1.51 95% CI 1.04–2.16), current smoker (RR = 1.61 95% CI 1.02–2.54), and at least a COVID-19 exposure (aRR = 2.13 95% CI 1.11–4.09). Male sex, age younger than 35 years, and low COVID-19 exposures were associated with better recovery and return to usual health. A third of patients presented persistent symptoms compatible with the long-COVID-19 syndrome. In conclusion, an active medical follow-up of post-COVID-19 patients must be implemented.

Objetivo. Analizar la reforma laboral en Brasil y en Chile en los últimos 5 años y su relación con la superexplotación del trabajo. Metodología. Se ha optado por realizar un análisis documental de sitios oficiales de los gobiernos de los países en cuestión e investigación teórica de textos y autores que abordan el tema. Resultados. Se constata que las mudanzas en las leyes laborales refuerzan el trabajo precario, mal remunerado, mantiene las altas tasas de concentración de renta y los índices elevados de pobreza, la dependencia al capital externo, la posición subalterna en la división internacional del trabajo y la garantía de la expropiación de la riqueza socialmente producida, a través de la extracción de plusvalía relativa y absoluta. Conclusión. Se considera que tal situación agrava los rasgos de la superexplotación del trabajo y atiende los intereses del capital internacional y sus agencias.

Acid mine drainage (AMD) systems are extremely acidic and are metal-rich formations inhabited by relatively low-complexity communities of acidophiles whose enzymes remain mostly uncharacterized. Indeed, enzymes from only a few AMD sites have been studied. The low number of available cultured representatives and genome sequences of acidophiles inhabiting AMDs makes it difficult to assess the potential of these environments for enzyme bioprospecting. In this study, using naïve and in silico metagenomic approaches, we retrieved 16 esterases from the α/β-hydrolase fold superfamily with the closest match from uncultured acidophilic Acidobacteria, Actinobacteria (Acidithrix, Acidimicrobium, and Ferrimicrobium), Acidiphilium, and other Proteobacteria inhabiting the Los Rueldos site, which is a unique AMD formation in northwestern Spain with a pH of ∼2. Within this set, only two polypeptides showed high homology (99.4%), while for the rest, the pairwise identities ranged between 4 and 44.9%, suggesting that the diversity of active polypeptides was dominated not by a particular type of protein or highly similar clusters of proteins, but by diverse non-redundant sequences. The enzymes exhibited amino acid sequence identities ranging from 39 to 99% relative to homologous proteins in public databases, including those from other AMDs, thus indicating the potential novelty of proteins associated with a specialized acidophilic community. Ten of the 16 hydrolases were successfully expressed in Escherichia coli. The pH for optimal activity ranged from 7.0 to 9.0, with the enzymes retaining 33–68% of their activities at pH 5.5, which was consistent with the relative frequencies of acid residues (from 54 to 67%). The enzymes were the most active at 30–65°C, retaining 20–61% of their activity under the thermal conditions characterizing Los Rueldos (13.8 ± 0.6°C). The analysis of the substrate specificity revealed the capacity of six hydrolases to efficiently degrade (up to 1,652 ± 75 U/g at pH 8.0 and 30°C) acrylic- and terephthalic-like [including bis(2-hydroxyethyl)-terephthalate, BHET] esters, and these enzymes could potentially be of use for developing plastic degradation strategies yet to be explored. Our assessment uncovers the novelty and potential biotechnological interest of enzymes present in the microbial populations that inhibit the Los Rueldos AMD system.

Este artículo indaga la relación entre las ideologías y las políticas activas de empleo considerando tres modelos de desarrollo en América Latina de principios del siglo xxi: neoliberalismo, neodesarrollismo y socialismo bolivariano, a partir de los casos muy poco estudiados en esta clave de Chile, Brasil y Venezuela. Mediante un análisis documental en distintos niveles: Constituciones, planes de gobierno y diseños de políticas de empleo, los resultados revelan que, si bien existen condicionantes globales, los gobiernos cuentan con un margen de maniobra para dar dirección y configurar proyectos históricos específicos. El diseño de las políticas de empleo expresa esa dirección, por lo que no son meros instrumentos técnicos neutros y transferibles de un país a otro.

Andean uplift and the concomitant formation of the Diagonal Arid of South America is expected to have promoted species diversification through range expansions into this novel environment. We evaluate the evolution of Argylia, a genus belonging to the Bignoniaceae family whose oldest fossil record dates back to 49.4 Ma. Today, Argylia is distributed along the Andean Cordillera, from 15°S to 38.5°S and from sea level up to 4,000 m.a.s.l. We ask whether Argylia’s current distribution is a result of a range expansion along the Andes Cordillera (biological corridor) modulated by climatic niche conservatism, considering the timing of Andean uplift (30 Ma – 5 Ma). To answer this question, we reconstructed the phylogenetic relationships of Argylia species, estimated divergence times, estimated the realized climatic niche of the genus, reconstructed the ancestral climatic niche, evaluated its evolution, and finally, performed an ancestral range reconstruction. We found strong evidence for climatic niche conservatism for moisture variables, and an absence of niche conservatism for most of the temperature variables considered. Exceptions were temperature seasonality and winter temperature. Results imply that Argylia had the capacity to adapt to extreme temperature conditions associated with the Andean uplift and the new climatic corridor produced by uplift. Ancestral range reconstruction for the genus showed that Argylia first diversified in a region where subtropical conditions were already established, and that later episodes of diversification were coeval with the of Andean uplift. We detected a second climatic corridor along the coastal range of Chile-Peru, the coastal lomas, which allowed a northward range expansion of Argylia into the hyperarid Atacama Desert. Dating suggests the current distribution and diversity of Argylia would have been reached during the Late Neogene and Pleistocene.

El artículo se propone indagar en la noción de ciudadanía liberal-marshalliana a la luz del impacto que tienen los procesos de neoliberalización en curso. Los hallazgos dan cuenta de que no se permite realizar la noción de ciudadanía, producto de los procesos de desposesión de derechos sociales, el endeudamiento y la creciente precarización del trabajo y la concentración de la riqueza. Para ello, aborda dos niveles de análisis: uno de orden conceptual acerca del concepto de ciudadanía, centrándose en la noción liberal, y un segundo nivel, que identifica las determinaciones del capitalismo dependiente contemporáneo y los límites del tipo de ciudadanía que es posible construir bajo esos parámetros en el contexto neoliberal. Metodológicamente se realiza una aproximación heurística de la obra de varios autores, en tanto fuentes primarias y secundarias.

ObjectiveMass gathering events (MGEs) are associated with the transmission of COVID-19. Between 6 and 10 March 2020, several MGEs related to the Falles festival took place in Borriana, a municipality in the province of Castellon (Spain). The aim of this study was to estimate the incidence of COVID-19 and its association with these MGEs, and to quantify the potential risk factors of its occurrence.MethodsDuring May and June 2020, a population-based retrospective cohort study was carried out by the Public Health Center of Castelló and the Hospital de la Plana in Vila-real. Participants were obtained from a representative sample of 1663 people with potential exposure at six MGEs. A questionnaire survey was carried out to obtain information about attendance at MGEs and COVID-19 disease. In addition, a serologic survey of antibodies against SARS-Cov-2 was implemented. Inverse probability weighted regression was used in the statistical analysis.ResultsA total of 1338 subjects participated in the questionnaire survey (80.5%), 997 of whom undertook the serologic survey. Five hundred and seventy cases were observed with an attack rate (AR) of 42.6%; average age was 36 years, 62.3% were female, 536 cases were confirmed by laboratory tests, and 514 cases were found with SARS-CoV-2 total antibodies. Considering MGE exposure, AR was 39.2% (496/1264). A dose-response relationship was found between MGE attendance and the disease, (adjusted relative risk [aRR] = 4.11 95% confidence interval [CI]3.25-5.19). Two MGEs with a dinner and dance in the same building had higher risks. Associated risk factors with the incidence were older age, obesity, and upper and middle class versus lower class; current smoking was protective.ConclusionsThe study suggests the significance of MGEs in the COVID-19 transmission that could explain the subsequent outbreak in Borriana.

Se realiza una reconstrucción teórica acerca de la noción de justicia social presente en tres tradiciones de la izquierda chilena: el Partido Comunista, el Partido Socialista y el Movimiento de Izquierda Revolucionaria (MIR). La historia de estas colectividades es abordada desde principios del siglo XX, pero especialmente a partir de la década del 50 hasta el golpe militar del año 1973. Los hallazgos dan cuenta de que la noción de justicia social de las tres corrientes tiende a coincidir y sustentarse en la dialéctica necesidad/libertad.We present a theoretical reconstruction of the notion of social justice, present in three traditions of the Chilean left: Communist Party, Socialist Party and the Revolutionary Left Movement (MIR). The history of these groups is considered from the start of the XX centuary, but especially since the 50’s until military coup in 1973. The findings show that: the notion of social justice of three groups tend to coincide and is sustained by is dialectic need/freedon.

La relevancia del uso de la noción de sociedad civil en algunas de las políticas públicas chilenas de los últimos años de los gobiernos de la Concertación obliga a escudriñar en algunos de los aparatos conceptuales -ubicados en los clásicos de la filosofía política- que están detrás de ese uso y revisar la construcción histórica de Chile que se ha realizado focalizando la relación entre Sociedad Civil y Estado. Lo anterior con el fin de explicarnos la relevancia y semántica que ha asumido hoy esa categoría en Chile -proceso no ajeno al movimiento en este sentido que se viene dando en diversos puntos del planeta desde hace algunas décadas-, como así también las tensiones y dificultades que llevan para avanzar en la democratización de nuestra sociedad.

The SARS-CoV-2 pandemic has caused an increase in antibiotic use in different settings.

This article specifies the key ideas of Socialism of the 21st century - at a theoretical level - which consider an unfinished political debate. Considering the ideological orientations expressed in the speeches of Hugo Chávez (2005-2013), the elements of continuity and rupture in his Latin-American perspective which constitute Bolivarian Socialism are analyzed. Based on these components, the article presents a key interpretation situated around socialist ideas with the objective of reflecting on the relevance and validity in our contemporary era.

Cet article compare la formation des noyaux identitaires dans les arts historiques italiques et hispaniques. Dans le cas italique, l'impact de la question linguistique, des académies et de la critique de l'humanisme latin sera abordé, tandis que dans le cas hispanique, le développement d'une conscience linguistique différentielle et la définition d'une Prisca Hispania préromaine seront traités. Ce dernier aspect révèle non seulement une rivalité avec la tradition italique et une prise de distance par rapport au mythe classiciste, mais aussi une tension interne entre les récits des origines (gothiques, turduli et tubalistes) et l'oscillation des historiens espagnols entre une vocation péninsulaire et une vocation universelle, liée à l'impérialisme hispanique.

When one exists outside the boundaries of what it means to be a person, let alone a ‘good’ womxn, the simple act of existing is a threat to the heteronormative standards present in one’s life (Alexander, 1994; Kempadoo, 2004, p. 27). Within the Caribbean, many colonial discourses on sexuality and race still exist today, where Caribbean womxn are harmed through dehumanizing stereotypes that pin their sexuality and agency with perversion, rejection of nature, and deviancy along with hypersexuality, immorality and purity, despite countries’ ‘independence’ of the colonial world (Reddock, 2007, p. 3-5; Kempadoo, 2004; Alexander, 1994). Using three visual pieces, I will put three of these harmful stereotypes in conversation with decolonial thought found in third-world feminism and Queer thought: “My Labour is Not Unskilled” with rejection of nature, “My Love is Not Unnatural” with perversion, and “My Body is My Own” with agency and opposition of hypersexuality.

Abstract Purpose To verify sociodemographic factors associated with the occurrence of abortion in women of reproductive age, in areas covered by the Family Health Strategy (FHS), a program from the Brazilian Ministry of Health. Methods A cross-sectional study using household surveys of 350 women aged 15 to 49. The report of abortion was a variable indicator, and sociodemographic aspects were covariables. Prevalence ratio (PR) and respective 95% confidence intervals were used to estimate the magnitude of the associations. Results There were associations among age, civil status, race/color, and religion; an increase in the prevalence of lower levels of education, age less than 20, and student status were protective factors. Conclusion The association between sociodemographic characteristics and the report of abortion is attributed to the fact that there is a lack at the FHS in the availability of fundamental healthcare services for young women; these findings call for action to guarantee the access to information about contraceptives and guidance to decrease the risk of unplanned pregnancies and abortions.

A Amazônia é foco de inúmeras discussões na atualidade, associadas sobretudo, a sua condição de desenvolvimento. Muitas são as perspectivas que permeiam as causas da condição atual da Amazônia no quadro social e econômico brasileiro, porém, grande parte destas, não conseguem apreender a realidade na sua totalidade, apresentando falhas quando utilizadas na construção de medidas para solução dos problemas apresentados. A complexidade da construção do espaço amazônico, requer uma leitura mais completa, envolvendo os diferentes elementos; econômicos, políticos, sociais e ideológicos. Sendo assim, este trabalho se propõe a realizar uma leitura da formação sócio-espacial da Amazônia a partir do processo de incorporação da fronteira, na tentativa de permitir que se compreenda o porquê da condição atual de desenvolvimento amazônico.

El presente artículo constituye una traducción española con aparato crítico de los prólogos escritos por Johannes Wolf (compilador) y Pietro Perna (tipógrafo) de la primera antología historiográfica del tardo-Renacimiento europeo, denominada Artis historicae Penus (1579); antología que formó parte de un proyecto editorial de nuevo cuño y sin precedentes en lo que respecta a sus propósitos y alcance. En el breve ensayo de presentación que antecede a la traducción se discuten cuatro aspectos relativos a la antología y sus autores: (i.) soportes materiales y paratextuales, (ii.) biográficos, (iii.) político-religiosos y (iv.) gnoseológico-pedagógicos.

O presente estudo busca contribuir com a discussão sobre a participação da iniciativa privada na provisão dos serviços de água e esgotamento sanitário no Brasil, a partir da análise comparativa do desempenho de dois grupos de prestadores: Empresas Privadas (EPs) e Sociedades de Economia Mista comAdministração Pública (SEMAPs). Para tanto, utilizar-se-á a técnica de programação matemática não paramétrica, denominada Análise de Envoltória de Dados (Data Envelopment Analysis - DEA), para identificar as operadoras e o grupo com as melhores práticas operacionais, sugerindo um plano de medidas para a otimização do desempenho das unidades ineficientes.

El trabajo intenta explicar el empleo dual que Cervantes, diferenciándose de la crítica europea al pedantismo, hace del vocablo "humanista": positivo y elogioso en Viaje del Parnaso (1614), negativo y paródico en la Segunda parte del Quijote (1615). Más allá de los requerimientos específicos propios de cada texto y la biografía del autor, se discute la convergencia de los factores que, a nuestro criterio, contribuyeron a forjar la original tipología cervantina, a saber: (i) las preocupaciones estéticas y gnoseológicas de la época, (ii) la conformación de un canon literario nacional (es decir, de un Parnaso español) y (iii) el grado de inserción concreta del modelo italiano de humanista en la España del siglo XVII.This paper attempts to explain the dual use that Cervantes makes, taking distance from the European criticism to pedantism, of the word "humanist": positive-laudatory in Viaje del Parnaso (1614), negative-parodic in the Second part of Don Quijote (1615). Beyond the specific requirements of each text and the author's life, it discusses the convergence of different aspects that, according to us, were crucial to build Cervantes' original typology: (i) certain aesthetic and gnoseological concerns of the period, (ii) the establishment of a national literary canon (that is to say, a Spanish Parnassus) and (iii) the kind of insertion that the Italian model of humanist had in Spain during the XVIIth century.

A mortalidade materna é um agravo que, a despeito de ser em sua maioria evitável, ainda se constitui em um graveproblema de saúde pública, que, no Brasil, atinge as classes sociais menos favorecidas. Pesquisa bibliográfica que objetivou analisar a produção científica de enfermagem sobre mortalidade materna na Revista Brasileira de Enfermagem, Revista Anna Nery e Revista Latino-Americana em Enfermagem, no período de 2000 a 2008. Utilizou-se para a busca dos artigos os descritores: saúde da mulher, enfermagem obstétrica e mortalidade materna. Do total de 2.370 artigos publicados por essas revistas no período, 158 apresentaram os descritores acima mencionados. Desses artigos, oito tratam da temática mortalidade materna. Os achados evidenciam participação de doutores e mestres na produção científica em enfermagem sobre mortalidade materna e uma articulação entre academia e universo prático. Sete artigos tratam de estudos quantitativos do tipo documental, com enfoque epidemiológico e um estudo retrata uma abordagem qualitativa, sendo o único a apresentar uma Teoria para fundamentação. As pesquisas não têm investigado a complexidade da temática que envolve questões de ordem individual e coletiva, ambas influenciadaspor problemas políticos e sociais a serem valorizados.

Introduction: Resistance to antibiotics is a growing problem with repercussions on the choice of first-line treatment in urinary tract infection (UTI) in childhood., Objectives: To know the current pattern of antibiotic susceptibility/resistance of the most frequent germs that cause UTI in our healthcare area. Secondary objective is to know the evolution of these patterns over time., Patients and Methods: A cross-sectional retrospective study of UTI episodes in a first-level hospital in two periods: 1st January 2008-31th December 2010 and 1st January 2017-31th December 2019 through a review of medical records, recording the following variables: Age, sex, fever, hospital admission, uropathy/bladder dysfunction, antibiotic prophylaxis., Results: First period: 174 UTI episodes (156 patients); Second period: 266 UTI episodes (218 patients). The most frequently isolated germ was E. coli , but in patients with uropathy or bladder dysfunction, the percentage of different germs is greater. A significant increase in resistance to amoxicillin/clavulanate (from 12.2 to 24%) is observed between both periods, it remains stable and in an acceptable range for gentamicin, cotrimoxazole and slightly increases to first-generation cephalosporins. In patients with uropathy/bladder dysfunction, resistance to all these antibiotics is significantly increased., Conclusions: The increased resistance of the most frequent uropathogens in the UTI of the pediatric population of our healthcare area to amoxicillin/clavulanate makes it unsuitable as empirical therapy. First-generation cephalosporins are an adequate alternative in patients without risk factors.
