Desarrollo del repertorio de equivalencia y de razonamiento analógico en población infantil: revisión conceptual

El presente trabajo presenta una revisión, desde una perspectiva contextual funcional, de los estudios dirigidos a delimitar las condiciones necesarias para el desarrollo de comportamientos simbólicos como las relaciones de equivalencia y el razonamiento analógico desde edades tempranas. Centrándonos en los estudios con población infantil, se ofrece una síntesis de las habilidades que se consideran relacionadas con dichos comportamientos simbólicos a distintos niveles y los procedimientos de evaluación y entrenamiento analizados, de cara a desarrollar programas de enseñanza normalizados o planes individuales de tratamiento para aquellos niños que muestren dificultades en su desarrollo.

Teoría de la Mente en un caso de autismo: ¿cómo entrenarla?

La Teoría de la Mente es una habilidad metacognitiva que en muchos casos se supone deficitaria en el autismo. Se presenta un estudio clínico con un niño diagnosticado de autismo, en el que se comprueba la efectividad de un protocolo de entrenamiento de las pruebas de falsas creencias, que se considera miden la Teoría de la Mente. Básicamente, el protocolo incorpora una serie de ayudas verbales (como enfatizar los elementos de las narraciones que indican cambios situacionales o temporales), se entrenan múltiples ejemplos, se amplían las pruebas incorporando objetos o juegos más cercanos a la vida cotidiana del niño, se aplican consecuencias diferenciales que permitan discriminar lo correcto de lo incorrecto y se proporciona feedback descriptivo. Los resultados reflejan cómo el protocolo de entrenamiento consigue el máximo nivel de correctos en las pruebas y el niño generaliza la habilidad de tomar perspectiva a su contexto natural

Expression of sterol regulatory element-binding proteins in epicardial adipose tissue in patients with coronary artery disease and diabetes mellitus: preliminary study

[Abstract] Objectives: Sterol regulatory element-binding proteins (SREBP) genes are crucial in lipid biosynthesis and cardiovascular homeostasis. Their expression in epicardial adipose tissue (EAT) and their influence in the development of coronary artery disease (CAD) and type-2 diabetes mellitus remain to be determined. The aim of our study was to evaluate the expression of SREBP genes in EAT in patients with CAD according to diabetes status and its association with clinical and biochemical data. Methods: SREBP-1 and SREBP-2 mRNA expression levels were measured in EAT from 49 patients with CAD (26 with diabetes) and 23 controls without CAD or diabetes. Results: Both SREBPs mRNA expression were significantly higher in patients with CAD and diabetes (p<0.001) and were identified as independent cardiovascular risk factor for coronary artery disease in patients with type-2 diabetes (SREBP-1: OR 1.7, 95%CI 1.1-2.5, p=0.02; SREBP-2: OR 1.6, 95%CI 1.2-3, p=0.02) and were independently associated with the presence of multivessel CAD, left main and anterior descending artery stenosis, and higher total and LDL cholesterol levels, and lower HDL cholesterol levels, in patients with CAD and diabetes. Conclusions: SREBP genes are expressed in EAT and were higher in CAD patients with diabetes than those patients without CAD or diabetes. SREBP expression was associated as cardiovascular risk factor for the severity of CAD and the poor lipid control. In this preliminary study we suggest the importance of EAT in the lipid metabolism and cardiovascular homeostasis for coronary atherosclerosis of patients with diabetes and highlight a future novel therapeutic target.Instituto de Salud Carlos III; PI13/02542Instituto de Salud Carlos III; PI11/01661Red de Investigación Cardiovascular; RD12/0042/003

A Large Multicenter Prospective Study of Community-Onset Healthcare Associated Bacteremic Urinary Tract Infections in the Era of Multidrug Resistance: Even Worse than Hospital Acquired Infections?

Introduction: Healthcare-associated (HCA) infections represent a growing public health problem. The aim of this study was to compare community-onset healthcare associated (CO-HCA) bacteremic urinary tract infections (BUTI) and hospital-acquired (HA)-BUTI with special focus on multidrug resistances (MDR) and outcomes. Methods: ITUBRAS-project is a prospective multicenter cohort study of patients with HCA-BUTI. All consecutive hospitalized adult patients with CO-HCA-BUTI or HA-BUTI episode were included in the study. Exclusion criteria were: patients \ 18 years old, non-hospitalized patients, bacteremia from another source or primary bacteremia, non-healthcare related infections and infections caused by unusual pathogens of the urinary tract. Th main outcome variable was 30-day all-cause mortality with day 1 as the first day of positive blood culture. Logistic regression was used to analyze factors associated with clinical cure at hospital discharge and with receiving inappropriate initial antibiotic treatment. Cox regression was used to evaluate 30-day all-cause mortality. Results: Four hundred forty-three episodes were included, 223 CO-HCA-BUTI. Patients with CO-HCA-BUTI were older (p \ 0.001) and had more underlying diseases (p = 0.029) than those with HA-BUTI. The severity of the acute illness (Pitt score) was also higher in CO-HCABUTI (p = 0.026). Overall, a very high rate of MDR profiles (271/443, 61.2%) was observed, with no statistical differences between groups. In multivariable analysis, inadequate empirical treatment was associated with MDR profile (aOR 3.35; 95% CI 1.77?6.35), Pseudomonas aeruginosa (aOR 2.86; 95% CI 1.27?6.44) and Charlson index (aOR 1.11; 95% CI 1.01?1.23). Mortality was not associated with the site of acquisition of the infection or the presence of MDR profile. However, in the logistic regression analyses patients with CO-HCA-BUTI (aOR 0.61; 95% CI 0.40?0.93) were less likely to present clinical cure. Conclusion: The rate of MDR infections was worryingly high in our study. No differences in MDR rates were found between CO-HCA-BUTI and HA-BUTI, in the probability of receiving inappropriate empirical treatment or in 30-day mortality. However, CO-HCA-BUTIs were associated with worse clinical cure.Funding. This study and the journal’s Rapid Service Fee are sponsored and funded by MSD Spain.

At the beginnings of the funerary Megalithism in Iberia at Campo de Hockey necropolis

[EN] The excavations undertaken at the Campo de Hockey site in 2008 led to the identification of a major Neolithic necropolis in the former Island of San Fernando (Bay of Cadiz). This work presents the results of the latest studies, which indicate that the site stands as one of the oldest megalithic necropolises in the Iberian Peninsula. The main aim of this work is to present with precision the chronology of this necropolis through a Bayesian statistical model that confirms that the necropolis was in use from c. 4300 to 3800 cal BC. The presence of prestige grave goods in the earliest and most monumental graves suggest that the Megalithism phenomenon emerged in relation to maritime routes linked to the distribution of exotic products. We also aim to examine funerary practices in these early megalithic communities, and especially their way of life and the social reproduction system. As such, in addition to the chronological information and the Bayesian statistics, we provide the results of a comprehensive interdisciplinary study, including anthropological, archaeometric and genetic data.We wish to express our gratitude to Antonio Saez Espligares (Historical Museum of San Fernando) and Lourdes Lorenzo (Figlina, s.l.) for their support during the archaeological excavation.

Prospective associations between a priori dietary patterns adherence and kidney function in an elderly Mediterranean population at high cardiovascular risk

Purpose To assess the association between three different a priori dietary patterns adherence (17-item energy reduced-Mediterranean Diet (MedDiet), Trichopoulou-MedDiet and Dietary Approach to Stop Hypertension (DASH)), as well as the Protein Diet Score and kidney function decline after one year of follow-up in elderly individuals with overweight/obesity and metabolic syndrome (MetS). Methods We prospectively analyzed 5675 participants (55-75 years) from the PREDIMED-Plus study. At baseline and at one year, we evaluated the creatinine-based estimated glomerular filtration rate (eGFR) and food-frequency questionnaires-derived dietary scores. Associations between four categories (decrease/maintenance and tertiles of increase) of each dietary pattern and changes in eGFR (ml/min/1.73m(2)) or >= 10% eGFR decline were assessed by fitting multivariable linear or logistic regression models, as appropriate. Results Participants in the highest tertile of increase in 17-item erMedDiet Score showed higher upward changes in eGFR (beta: 1.87 ml/min/1.73m(2); 95% CI: 1.00-2.73) and had lower odds of >= 10% eGFR decline (OR: 0.62; 95% CI: 0.47-0.82) compared to individuals in the decrease/maintenance category, while Trichopoulou-MedDiet and DASH Scores were not associated with any renal outcomes. Those in the highest tertile of increase in Protein Diet Score had greater downward changes in eGFR (beta: - 0.87 ml/min/1.73m(2); 95% CI: - 1.73 to - 0.01) and 32% higher odds of eGFR decline (OR: 1.32; 95% CI: 1.00-1.75). Conclusions Among elderly individuals with overweight/obesity and MetS, only higher upward change in the 17-item erMedDiet score adherence was associated with better kidney function after one year. However, increasing Protein Diet Score appeared to have an adverse impact on kidney health.

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Desarrollo del repertorio de equivalencia y de razonamiento analógico en población infantil: revisión conceptual

El presente trabajo presenta una revisión, desde una perspectiva contextual funcional, de los estudios dirigidos a delimitar las condiciones necesarias para el desarrollo de comportamientos simbólicos como las relaciones de equivalencia y el razonamiento analógico desde edades tempranas. Centrándonos en los estudios con población infantil, se ofrece una síntesis de las habilidades que se consideran relacionadas con dichos comportamientos simbólicos a distintos niveles y los procedimientos de evaluación y entrenamiento analizados, de cara a desarrollar programas de enseñanza normalizados o planes individuales de tratamiento para aquellos niños que muestren dificultades en su desarrollo.

La correspondencia entre saber y hacer en el caso del educador

La correspondencia entre lo que un profesor conoce acerca del quehacer efectivo para fomentar comportamientos positivos en clase y lo que hace no es siempre un hecho. El presente estudio analiza diferentes condiciones para facilitar la correspondencia entre saber lo que hacer respecto a conductas disruptivas de los niños en clase y hacerlo. Participaron niños (de 7 a 11 años) normales y algunos con ligero retraso que pertenecían a dos aulas controladas por el mismo profesor. Tras un período de registro sobre el comportamiento inadecuado de los niños y del educador (fase A), se aplicaron diferentes condiciones: instruir normas claras a los alumnos (fase B), discriminación, por parte del educador, de su propia conducta correcta e incorrecta (fase C), y ayuda directa para la prevención de respuestas incorrectas por parte del profesor (fase D). Se utilizó un diseño intragrupo multivariable ABCD en la clase I y AC en la clase II, lo que presenta un diseño de Línea Base Múltiple a través de clases respecto a la condición de discriminación de la propia conducta (C). Las conductas inapropiadas de los niños y del profesor se redujeron durante la condición C y quedaron sustituidas totalmente por un buen hacer con la ayuda direct
