No full textSevere pneumonia in Young smokers in the province of Buenos Aires
No full textIntroduction: Smoking is related to morphological alterations of the bronchial mucosa epithelium. In Argentina, 33.4% of the population between 18 and 64 years of age are smokers, with a predominance in the lower income areas of the country. According to the World Health Organization (WHO), 1.6 million people die of pneumonia every year, with smoking being a major risk factor for its development. Materials and methods: A prospective observational descriptive study was carried out at the Eurnekian Hospital in Ezeiza to describe the evolution of young adult patients with severe pneumonia. Data was collected through anamnesis and review of physical medical records of patients admitted with a diagnosisof pneumonia. Results: Thirty-eight young immunocompetent patients hospitalized with pneumonia were analyzed. The average age was 40 years, with a predominance of males (70.7%). The average number of years of consumption was 20, and 20 patients (55.2%) of the total were minors at the beginning of their smoking habit. With regard to the presence of previous pathologies, 7 patients (18.2%) were diabetic, 9 were hypertensive, 3 had suffered an acute myocardial infarction, 4 had suffered a cerebrovascular accident; 3 had advanced heart failure, 1 had renal failure and 3 had suffered tuberculosis for which they had received full treatment. With regard to oxygen saturation on admission to hospital, 8 patients had saturation levels of between 80-84.9%, 21 between 85-90% and 9 >90%. The average length of stay in hospital was 5.8 days, with only 9 patients being hospitalized for between 10-14 days. Conclusion: The results show that the onset of smoking habit is prior to the age of majority. We believe it is advisable to carry out more campaigns for the prevention of addictions and smoking cessation in adolescents and young adults, with an emphasis on primary health prevention.
La teoría mimética aplicada a las relaciones interpersonales a través de redes sociales:: el caso de piñagate en Mercadona
No full textIntroduction:Piñagateillustrates how social networks amplify mimetic behaviours. It analyses how desires and behaviours are digitally replicated, highlighting the role of tweets and viral content in their expansion. This case provides new perspectives on mimetic theory applied to digital phenomena and its impact on contemporary communication. Methodology:The analysis was carried out by collecting tweets with ‘pineapple’ AND ‘Mercadona’ AND ‘flirt’. After data cleaning in Excel and Google Colab, a sentiment analysis was carried out with Pipeline (Transformers) to subsequently extract keywords with NLTK and elaborate thematic maps with VOSviewer. Results:The results indicate that the content of the tweets analysed has a positive tone or a favourable response from the community analysed. Four groups are identified: General Context of Mercadona, Strategies for Flirting, Environments and Products, and Moments and Occasions. Discussion:The application of mimetic theory to social networks has generated both interest and criticism. Some argue that it provides a valuable explanation for understanding online behaviour and group dynamics. However, others criticise that it may oversimplify the complexity of human interactions and individual motivations. Conclusions:The piñagate at Mercadona illustrates how mimetic theory explains viral phenomena in social networks, highlighting how trivial symbols, such as a pineapple, are transformed into acts of interpersonal communication. This study combines data analysis and natural language, showinghow digital culture redefines social norms and commercial perceptions.Introducción: El piñagate ilustra cómo las redes sociales amplifican comportamientos miméticos. Se analiza cómo deseos y comportamientos se replican digitalmente, destacando el papel de tuits y contenidos virales en su expansión. Este caso aporta nuevas perspectivas sobre la teoría mimética aplicada a fenómenos digitales y su impacto en la comunicación contemporánea. Metodología :El análisis se llevó a cabo mediante la recolección de tuits con “piña” AND “Mercadona” AND “ligar”. Tras la limpieza de datos en Excel y Google Colab se hizo un análisis de sentimiento con Pipeline (Transformers) para, posteriormente extraer las palabras clave con NLTK y elaborar los mapas temáticos con VOSviewer. Resultados: Los resultados indican que el contenido de los tuits analizados tiene un tono positivo o una respuesta favorable de la comunidad analizada. Se identifican cuatro grupos: Contexto General de Mercadona, Estrategias para Ligar, Ambientes y Productos, y Momentos y Ocasiones. Discusión: La aplicación de la teoría mimética a las redes sociales ha generado tanto interés como críticas. Algunos argumentan que proporciona una explicación valiosa para entender el comportamiento en línea y las dinámicas de grupo. Sin embargo, otros critican que puede simplificar excesivamente la complejidad de las interacciones humanas y las motivaciones individuales.
Conclusiones: El piñagate en Mercadona ilustra cómo la teoría mimética explica fenómenos virales en redes sociales, destacando cómo símbolos triviales, como una piña, se transforman en actos de comunicación interpersonal. Este estudio combina análisis de datos y lenguaje natural, mostrando cómo la cultura digital redefine normas sociales y percepciones comerciales

Evaluación de diferentes estrategias de fertilización en el control del rajado de tallos en alstroemeria variedad ‘Bali’
No full textContextualization: Alstroemeria is a flower with great beauty, a wide range of colors, a long vase life, and a growing popularity worldwide.
Knowledge gap: One of the main problems affecting cut flowers' quality in alstroemeria cultivation is the longitudinal cracking of the stem present during the first weeks of growth, which causes a loss of production and commercial quality.
Purpose: The objective was to evaluate different fertilization strategies to control stem cracking in the alstroemeria variety ‘Bali.’
Methodology: Using a completely randomized experimental design, five treatments were evaluated: control with conventional fertilization, treatment with additional irrigation, additional urea, additional foliar fertilization based on Ca, B, K, and P, and the last with additional potassium sulfate, whose application was carried out one week after sowing.
Results and conclusions: The application of potassium sulfate showed the highest values of stem diameter with 0.835 cm. The number of flowers per stem was not significantly affected. However, the application of potassium sulfate showed higher values of 7.38 flowers per stem at 27 weeks after sowing. Additional foliar fertilization with calcium, boron, potassium, and phosphorus was significantly affected by increasing production and reducing the percentage of cracked stems in the Alstroemeria crop. It is essential to distribute the quantities of nitrogen in a greater number of applications during the development of the crop to avoid disproportionate growth of the stem and prevent physiopathies.Contextualización: La alstroemeria es una flor con gran belleza, amplia gama de colores, larga vida en florero y con una creciente popularidad a nivel mundial.
Vacío de investigación: Uno de los principales problemas que afecta la calidad de la flor de corte en el cultivo de alstroemeria es el rajado longitudinal del tallo presente durante las primeras semanas de crecimiento, lo cual origina la pérdida de producción y de calidad comercial.
Propósito del estudio: el objetivo fue evaluar diferentes estrategias de fertilización en el control del rajado de tallos en alstroemeria variedad ‘Bali’.
Metodología: mediante un diseño experimental completamente aleatorizado, se evaluaron cinco tratamientos: testigo con fertilización convencional, tratamiento con riego adicional, urea adicional, fertilización foliar adicional a base de Ca, B, K y P, y el último con sulfato de potasio adicional, cuya aplicación se realizó una semana después de la siembra.
Resultados y conclusiones: La aplicación de sulfato de potasio mostró los mayores valores de diámetro del tallo con 0,835 cm. El número de flores por tallo no se vio afectado de forma significativa, no obstante, la aplicación de sulfato de potasio mostró valores superiores de 7,38 flores por tallo a las 27 semanas después de siembra. La fertilización foliar adicional con calcio, boro, potasio y fósforo afectó de manera significativa, al aumentar la producción y reducir el porcentaje de tallos rajados en el cultivo de Alstroemeria. Es fundamental distribuir en un mayor número de aplicaciones las cantidades de nitrógeno durante el desarrollo del cultivo para evitar un crecimiento desproporcionado del tallo y prevenir fisiopatías
Influencia de la región y tostión en la identificación de grupos funcionales de cafés colombianos mediante espectroscopía infrarroja
No full textKnowledge gap: Currently, it is uncertain how roasting, and region affect the presence of functional groups that can be associated with the presence of specific bioactive compounds in the grain. Therefore, infrared spectrophotometry techniques emerge as the methodologies for rapid and presumptive analysis of coffee quality.
Results and conclusions: of the spectra, 14 bands were identified with functional groups of interest that relate the presence of chemical compounds. Among these were found alcohols, aromatic rings, caffeine, lipids, aldehydes, esters, organic acids (chlorogenic), trigonelline, aliphatic acids and carbohydrates. Of the influence of roasting and region on the presence of functional groups, the coffees of Cauca (mild roasting), Santander (balanced roasting) and Caldas (strong roasting) were the ones with the highest vibration in the 14 peaks found in relation to their homonyms. However, the principal component analysis showed that mild roast coffees (Tolima, Nariño and Cauca) and Caldas in strong roasting were the ones with the greatest influence on the compounds associated with the functional groups found. Cauca and Caldas are the predominant in the functional groups, indicating that the region and the roasting significantly affect the presence of functional groups and the internal composition of the grain.Contextualización: El café es uno de los frutos de mayor riqueza funcional y bioactiva. Sin embargo, condiciones como la región de cultivo, manejo poscosecha y calidad del tueste pueden afectar la composición e identificación de grupos funcionales.
Vacío de conocimiento: Actualmente, es incierto cómo afectan la tostión y la región en la presencia de grupos funcionales que se puedan asociar con la presencia de compuestos bioactivos específicos en el grano, por lo cual, las técnicas de espectrofotometría infrarroja surgen como las metodologías de análisis rápido y presuntivo de calidad cafetera.
Propósito: El objetivo de investigación fue evaluar la influencia de la región y tostión en la identificación de grupos funcionales de cafés colombianos analizados mediante espectroscopía infrarroja y quimiometría.
Metodología: Se emplearon cafés colombianos variedad arábica de diferente grado de tostión y región según su tostión: tostión suave (Cauca, Tolima y Nariño), tostión balanceada (Huila, Antioquia y Santander) y tostión fuerte (Caldas, Valle del Cauca y Sierra Nevada). Los cafés fueron analizados mediante espectroscopía infrarroja por reflectancia total atenuada de 4000 a 600 cm-1.
Resultados y conclusiones: De los espectros se identificaron 14 bandas con grupos funcionales de interés que relacionan la presencia de compuestos químicos. Dentro de estos se encontraron alcoholes, anillos aromáticos, cafeína, lípidos, aldehídos, ésteres, ácidos orgánicos (clorogénico), trigonelina, ácidos alifáticos y carbohidratos. De la influencia de la tostión y la región sobre la presencia de grupos funcionales, los cafés de Cauca (tostión suave), Santander (tostión balanceada) y Caldas (tostión fuerte) fueron los de mayor vibración en los 14 picos encontrados en relación con sus homónimos. Sin embargo, el análisis de componentes principales arrojó que los cafés de tostión suave (Tolima, Nariño y Cauca) y tostión fuerte (Caldas) fueron los de mayor influencia sobre los compuestos asociados a los grupos funcionales encontrados, siendo Cauca y Caldas los predominantes en los grupos funcionales, indicando que la región y la tostión afectan significativamente la presencia de grupos funcionales y la composición interna del grano
