Quality and effectiveness of osteoporosis treatment decision aids: a systematic review and environmental scan
Decision aids (DAs) are evidence-based tools that support shared decision-making (SDM) implementation in practice; this study aimed to identify existing osteoporosis DAs and assess their quality and efficacy; and to gain feedback from a patient advisory group on findings and implications for further research. We searched multiple bibliographic databases to identify research studies from 2000 to 2019 and undertook an environmental scan (search conducted February 2019, repeated in March 2020). A pair of reviewers, working independently selected studies for inclusion, extracted data, evaluated each trial’s risk of bias, and conducted DA quality assessment using the International Patient Decision Aid Standards (IPDAS). Public contributors (patients and caregivers with experience of osteoporosis and fragility fractures) participated in discussion groups to review a sample of DAs, express preferences for a new DA, and discuss plans for development of a new DA. We identified 6 studies, with high or unclear risk of bias. Across included studies, use of an osteoporosis DA was reported to result in reduced decisional conflict compared with baseline, increased SDM, and increased accuracy of patients’ perceived fracture risk compared with controls. Eleven DAs were identified, of which none met the full set of IPDAS criteria for certification for minimization of bias. Public contributors expressed preferences for encounter DAs that are individualized to patients’ own needs and risk. Using a systematic review and environmental scan, we identified 11 decision aids to inform patient decisions about osteoporosis treatment and 6 studies evaluating their effectiveness. Use of decision aids increased accuracy of risk perception and shared decision-making but the decision aids themselves fail to comprehensively meet international quality standards and patient needs, underpinning the need for new DA development
Competency Model for Product Owners and Product Managers
The objective of this article is to develop a competency model for Product Owners and Product Managers that enables them to perform successfully in their roles. The article goes through several stages, with the first being the study and analysis phase. In this stage, the problems, related work for the mentioned roles, and the literature used for the model design process will be analyzed. Subsequently, the competency model for Product Owners and Product Managers will be designed to establish the competencies that these roles should possess. This will also help companies in hiring qualified individuals for product development. Finally, the model will be validated through the evaluation of experts in the field, using virtual interviews and a Likert scale-based survey. These techniques will allow for the collection of quantitative data to support the validity of the model. © 2023 CISCI 2023 - Vigesima Segunda Conferencia Iberoamericana en Sistemas, Cibernetica e Informatica, Vigesimo Simposium Iberoamericano en Educacion, Cibernetica e Informatica, SIECI 2023Revisión por pare

Sustainable Concrete with Rice Husk Ash (RHA) for Marine Structures
In recent years, attention has focused on addressing the environmental problems caused by the use of construction materials, proposing to develop new environmentally friendly concrete; One of the alternatives that has emerged is to replace cement or aggregates with agricultural waste because its treatment is expensive and not very sustainable; This is the case of rice husk ash (RHA), the main agricultural residue resulting from this cereal, which represents an abundant production worldwide. Marine reinforced concrete structures are in constant exposure to the marine environment, so that their structural capacity and useful life are affected by the breakdown of aggregates, which cause a greater amount of free CaO and MgO in concrete mixtures, and the penetration of chloride ions, which destroy the passive layer of steel and produce cracks in the concrete that cause loss of load and structural damage. In this investigation, cylindrical specimens of conventional concrete and sustainable concrete with cement replacement percentages of 5%, 10% and 15% RHA have been developed. The results show that for a 5% RHA replacement, the compressive strength is greater than conventional concrete at an early age; the disintegration of the aggregates decreases, being for the fine of 9.86% and for the coarse aggregate of 4.34%, the penetrability of sulfate ions decreases as the percentage of RHA replacement increases, the permeability of conventional concrete is much greater with respect to RHA replacement concrete and, finally, the unit cost analysis per cubic meter of RHA concrete is less than conventional concret
Implementación de Sistemas de Lecciones Aprendidas: Explorando la Confianza Como Factor de Éxito
Este artÃculo describe los resultados de un estudio exploratorio sobre un factor de éxito para la implementación de sistemas delecciones aprendidas: la confianza. Se llega a la conclusión que existe una alta correlación entre la confianza que perciben lostrabajadores de conocimiento de las organizaciones que han adoptado sistemas de lecciones aprendidas y el éxito en laimplementación de estos sistemas. Aunque no es el único factor importante para lograr el éxito en la implementación, laliteratura señala que la confianza es parte del concepto de cultura de conocimiento y por ello un factor esencial de éxito. Elestudio se realizó en un grupo de empresas de consultorÃa en sistemas y tecnologÃas de información y se encuestó a sustrabajadores de conocimiento. Los resultados comprueban la literatura vigente e informa a los gerentes sobre la importanciade invertir en programas de desarrollo del sentimiento de confianza entre sus colaboradores
Biological activity of the Euphorbiaceae and Moraceae families of medicinal plants present in the Northern Coast of Colombia: worldwide overview and their therapeutic potential
The Euphorbiaceae and Moraceae families in Colombia are distributed along the northern coast of Colombia, have been traditionally used by native communities for different purposes, and represent a promising source of molecules with therapeutic activity, whose effectiveness has been verified internationally through biological assays. A systematic review of the existing literature was carried out and data on taxonomy, world distribution, phytoconstituents, ethnopharmacology and pharmacological activity of the Euphorbiaceae and Moraceae families were collected using several databases such as PubMed, CAplus, Medline, Latin America & Iberia database, Science Direct, Web of Science and Google Scholar, Abstracts. The pharmacological activities reported were antioxidant, anti-inflammatory, anti-hypertensive and antileishmanial. In conclusion, the Euphorbiaceae and Moraceae families are important producers of active metabolites with high impact on public health, which strengthens the Colombian Caribbean as a center for the generation of molecules for the pharmaceutical field.
 
Variación de salinidad afecta ritmo de crecimiento poblacional y capacidad reproductiva de Brachionus plicatilis: un enfoque al cambio climático
Revista Iberoamericana De BioeconomÃa Y Cambio Climático E-ISSN 2410-7980, 7(14), 1587-1599El objetivo del presente estudio consistió en evaluar, en condiciones de no aclimatación, el ritmo de crecimiento poblacional y la capacidad reproductiva de Brachionus plicatilis, tras el sometimiento a estrés por salinidad reducida. El dÃa del experimento se colocaron en una baterÃa de cuatro grupos experimentales (1: aclimatados y 3: sin aclimatar): grupo control (35 ‰), Tratamiento 1 (25 ‰), Tratamiento 2 (10 ‰) y Tratamiento 3 (7 ‰), N= 30 rot/ml. Se usó agua destilada para reducir la salinidad. Los rotÃferos se cultivaron a temperatura de 31±1ºC, pH 8.33 y se alimentaron con una única dosis de Saccharomyces cerevisiae (1 x 106 cel/ml). Se utilizó aireación constante durante todo el experimento. Los rotÃferos se contaron una vez al dÃa. Los resultados muestran que los rotÃferos cultivados en las salinidades de 35 ‰ y 25 ‰ presentan mayor ritmo de crecimiento poblacional y capacidad reproductiva que los cultivados en 10 y 7 ‰, durante los dos dÃas de estudio. Asimismo, a 35 ‰ se corresponden los mayores valores de tasa de crecimiento (K: 1.66) y rendimiento (r: 129), seguido de 25 ‰. No obstante, en 25 ‰ se observó la mayor cantidad de rotÃferos en etapa reproductiva (96 % de rotÃferos con huevos y valor de Ãndice reproductivo de 0.964). Por consiguiente, nuestros resultados muestran que B. plicatilis, cuando está cultivado en agua marina (35 ‰) y se traslada sin previa aclimatación a medios con salinidad reducida disminuye su tasa de crecimiento y rendimientoUNAN-León, Escuela de ciencias agrarias y veterinarias/ Departamento de AgroecologÃa/Centro de Investigación en Bioeconomia y Cambio climatic
