Clima organizacional y sensibilidad a la crítica de alumnos de la facultad de psicología de una universidad pública de Lima

This communication reports the adaptation and relationship between the scale of organizational climate and sensitivity to criticism on 338 students of undergraduate, of which 140 are male and 198 female of the faculty of psychology of public university of Lima. Organizational climate scale was finally restructured into four factors: a) factor 1: negative attitude towards the organization (19 items), b) factor 2: quality of work (8 items), c) factor 3: institutional image (4 items), and d) factor 4: competition authority (6 items); while the scale of sensitivity to criticism maintained its very structure. The results arrogated the lack of relationship between organizational climate and sensitivity to criticism, in the same way sex and age does not make a difference with these.La presente comunicación reporta la adaptación y la relación entre la escala de clima organizacional y la sensibilidad a la crítica en 338 alumnos de pregrado, de los cuales 140 son del sexo masculino y 198 del femenino de la facultad de psicología de una universidad pública de Lima.

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

Enfermedad femoropoplítea como primera manifestación clínica en pacientes con isquemia arterial aguda trombótica de miembros inferiores

Our research was on 243 patient�s clinical histories with the clinical diagnosis of isquemia arterial sharp thrombotic of inferior members, they were attending by health services at the national institute of angiología and vascular surgery In the Havana, Cuba, in the understood period of January 1997 to December 2007. Most of the studied patients had more than 60 years of age, with prevalence of the sector femoropopliteo 78.4% with relationship to the aortoiliaco 69.4%. The diabetes mellitus was the factor of exposure risk for the outcome, you presents in both groups of patient with femoropopliteal illness y/o aortoiliaca respectively. The surgical more used in our patients as final result, in the evolution of the event sharp isquémico.La presente investigación comprendió el análisis de 243 historias clínicas de pacientes con diagnóstico clínico de isquemia arterial aguda trombótica de miembros inferiores, pertenecientes al archivo del Instituto Nacional de Angiología y Cirugía Vascular, de la Habana, Cuba, en el período comprendido de enero 1997 a diciembre 2007. La mayoría de los pacientes estudiados tenían más de 60 años de edad, con predominio de la enfermedad en el sector femoropopliteo (78.4%) con relación al aortoiliaco (69.4%). La diabetes mellitus como factor de riesgo independiente para la enfermedad, se presentó en ambos grupos de pacientes con enfermedad femoropoplitea y/o aortoiliaca respectivamente. Al mayor número de pacientes que presentaron una isquemia arterial aguda trombótica de miembros inferiores, se le realizaron sus diagnósticos positivos después de las 72 horas. El tratamiento quirúrgico fue el más utilizado en estos pacientes como resultado final en la evolución del evento isquémico agudo

Mass dependence of inclusive nuclear phi photoproduction

Based on a prior determination of the phi selfenergy in a nuclear medium we perform a theoretical study of inclusive phi photoproduction in nuclei, looking at the A dependence of the cross sections for different phi momenta. We find sizeable reductions in the nuclear cross sections with respect to the elementary one, using a phi selfenergy which implies a width about six times the free one at normal nuclear density. The calculations are done to match the set up for an ongoing experiment at SPring8/Osaka which should provide valuable information on the renormalization of the phi properties in nuclei

{'en_US': "Patient's experiences of being diagnosed with chronic kidney disease and being admitted to peritoneal dialysis", 'es_ES': 'Vivencias del paciente ante el diagnóstico de enfermedad renal crónica y su ingreso a diálisis peritoneal'}

Introducción: Un número importante de pacientes que ingresan al programa de diálisis peritoneal reciben simultaneamente la noticia de que tienen enfermedad renal crónica en etapa terminal y requieren diálisis peritoneal. Para muchos de ellos la noticia es inesperada y desconsoladora, ya que tienen que acceder a la diálisis para poder seguir viviendo. Material y Método: Estudio cualitativo, descriptivo con enfoque fenomenológico. De 106 pacientes incidentes del programa de diálisis peritoneal ambulatoria a quienes se les solicitó consentimiento informado para contestar el instrumento (Coping Inventory Strategies), se seleccionaron 14 pacientes que relataron sus vivencias respecto a su diagnóstico de enfermedad renal crónica y la necesidad urgente de diálisis peritoneal. Se les pidió que escribieran en una cuartilla cómo enfrentaron la noticia de insuficiencia renal crónica y requerir diálisis peritoneal. Resultados: Se incluyeron en el estudio a 14 pacientes, con edad comprendida entre 41 y 61 años, y el 66% fueron mujeres. Se identificaron tres categorías y siete subcategorías: sociolaboral (estigma social e incertidumbre por el trabajo); actitud ante la muerte (resignación y sentimiento de culpa) y acompañamiento familiar (toma de decisiones, motivación y apoyo). El mayor número de pacientes se ubicó en la categoría de actitud ante la muerte y en la subcategoría de resignación como estrategia de afrontamiento. Conclusiones: Los pacientes describieron la fase en la que se enteraron de su diagnóstico y el ingreso a diálisis peritoneal como el momento más difícil y traumático, manifestaron sentimientos de angustia, limitaciones personales o sociales y reconocieron la dependencia del apoyo familiar

Scalable Synthesis and Electrocatalytic Performance of Highly Fluorinated Covalent Organic Frameworks for Oxygen Reduction

In this study, we present a novel approach for the synthesis of covalent organic frameworks (COFs) that overcomes the common limitations of non-scalable solvothermal procedures. Our method allows for the room-temperature and scalable synthesis of a highly fluorinated DFTAPB-TFTA-COF, which exhibits intrinsic hydrophobicity. We used DFT-based calculations to elucidate the role of the fluorine atoms in enhancing the crystallinity of the material through corrugation effects, resulting in maximized interlayer interactions, as disclosed both from PXRD structural resolution and theoretical simulations. We further investigated the electrocatalytic properties of this material towards the oxygen reduction reaction (ORR). Our results show that the fluorinated COF produces hydrogen peroxide selectively with low overpotential (0.062 V) and high turnover frequency (0.0757 s-1 ) without the addition of any conductive additives. These values are among the best reported for non-pyrolyzed and metal-free electrocatalysts. Finally, we employed DFT-based calculations to analyse the reaction mechanism, highlighting the crucial role of the fluorine atom in the active site assembly. Our findings shed light on the potential of fluorinated COFs as promising electrocatalysts for the ORR, as well as their potential applications in other fields.Depto. de Química InorgánicaDepto. de Química OrgánicaFac. de Ciencias QuímicasTRUEpubDescuento UC
