A Randomized Clinical Trial Evaluating the Efficacy of an Anthocyanin–Maqui Berry Extract (Delphinol®) on Oxidative Stress Biomarkers
Objective: Berries are a rich source of anthocyanins, and clinical data suggest that a polyphenol-rich diet may exert health-promoting effects by reducing oxidative stress. The aim of this study was to elucidate the effects of dietary supplementation with Delphinol (trademark owned by MNL Chile) standardized maqui berry (Aristotelia chilensis) extract on products of lipid peroxidation in healthy, overweight, and smoker subjects.Methods: In a double-blind, placebo-controlled design, 42 participants (age 45-65years) consumed in random order either a standardized extract of maqui berry (162mg anthocyanins) or a matched placebo, given 3times daily for 4weeks. The samples were collected at baseline, after the end of the supplementation, and 40days after the end of the study. Primary outcome was the measure of oxidized low-density lipoprotein (Ox-LDL) and F-2-isoprostanes in plasma and urine, respectively. Secondary outcomes included anthropometric measures, blood pressure, and lipid profile.Results: Delphinol supplementation was associated with reduced levels of Ox-LDL in the anthocyanin group compared to baseline (p < 0.05). There was also a decrease in urinary F-2-isoprostanes (8-iso-prostaglandin F2) at 4weeks versus baseline in the Delphinol-supplemented group (p < 0.05). However, no differences in primary outcomes were evident at 40days of follow-up. In the fourth week of the intervention, no significant differences were noted for anthropometric characteristics, ambulatory blood pressure, and lipid profile.Conclusions: Our observations suggest that dietary interventions with maqui berry extract may improve oxidative status (Ox-LDL and F-2-isoprostanes) in healthy adults, overweight adults, and adult smoke
Metagenome sequencing of the microbial community of a solar saltern crystallizer pond at cáhuil lagoon, chile.
Cáhuil Lagoon in central Chile harbors distinct microbial communities in various solar salterns that are arranged as interconnected ponds with increasing salt concentrations. Here, we report the metagenome of the 3.0- to 0.2-µm fraction of the microbial community present in a crystallizer pond with 34% salinity
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
Descubrimiento de patrones de comportamiento vinculados al abandono en la Universidad Nacional de Luján mediante la aplicación de técnicas de aprendizaje automático
El estudio del abandono en la educación superior resulta un tema de relevancia dado el continuo debate que se propicia respecto de los recursos públicos que las naciones afectan a su sostenimiento, principalmente en Argentina, donde el subsistema de gestión pública abarca más del 75 % de la matrícula total del sistema. Las altas tasas de abandono ponen en tensión la política de gratuidad e ingreso irrestricto que se aplica históricamente y que es reconocido como uno de los medios para la movilidad social.
La multicausalidad del fenómeno requiere de su estudio y análisis desde diferentes perspectivas asá como de la definición de políticas académicas para tratar de disminuir el fracaso educativo en el nivel superior.
Por su parte, en la actualidad, existen numerosas técnicas de ciencia de datos mediante las cuales es posible extraer conocimiento a partir de bases de datos, las cuales están siendo aplicadas a áreas muy disímiles. Estas técnicas permiten encontrar patrones que no podrán ser descubiertos mediante las técnicas convencionales de análisis de datos multivariantes.
En este trabajo se describen las acciones emprendidas en el marco del proyecto de investigación “Descubrimiento de patrones de comportamiento vinculados al abandono en la Universidad Nacional de Luján mediante la aplicación de técnicas de aprendizaje au- tomatico”, así como las líneas de I+D comprendidas en el mismo.Red de Universidades con Carreras en Informátic
