Calidad de vida relacionada con la salud, Expectativas y Satisfacción Académica de jóvenes universitarios

Introducción: El objetivo del trabajo fue determinar la relación entre las dimensiones de la calidad de vida relacionada con la salud y las expectativas académicas de resultado, las expectativas de futuro, metas de progreso y la satisfacción escolar de jóvenes universitarios. Método: La investigación fue observacional, descriptiva, correlacional y con diseño transeccional. En este estudio participaron 346 jóvenes universitarios (51 %= hombres y 49 % mujeres), de 18 a 23 años, la forma de selección de la muestra fue por conveniencia. Se utilizó el cuestionario SF-12 que evalúa la calidad de vida relacionada con la salud en ocho dimensiones; función física, rol físico, dolor corporal, salud general, vitalidad, función social, rol emocional y salud mental, y las escalas de; expectativas académicas de resultado, metas de progreso académicas, satisfacción escolar y expectativas de futuro. Resultados: Los resultados indican la existencia de altos puntajes en dimensiones como la función física, rol físico y rol emocional, excepto en la función social. Se observó correlación entre las dimensiones que integran el componente de salud física con las expectativas académicas, satisfacción académica y expectativas de futuro. A su vez, el componente de salud mental se correlacionó con las metas de progreso académicas, expectativas académicas de resultado, satisfacción académica y expectativas de futuro. Conclusiones: los jóvenes universitarios tienen una buena calidad de vida, sin embargo, existe una proporción de estudiantes que no adoptan hábitos saludables y otros sí. La salud física y mental son aspectos importantes en los estudiantes, no obstante, los universitarios no visualizan el impacto de dichos beneficios en el éxito escolar, el logro de sus expectativas académicas, metas de progreso e incluso en sus expectativas de futuro.

Background: The study aimed to determine the relationship between the dimensions of health-related quality of life and the academic expectations of the outcome, future expectations, progress goals, and school satisfaction of young university students. Method: The research was observational, descriptive, correlational, and with a transitional design. In this study, 346 young university students (51% = men and 49% women) participated, from 18 to 23 years old, the form of a selection of the sample was for convenience. The SF-12 questionnaire was used, which evaluates the health-related quality of life in eight dimensions; physical function, physical role, body pain, general health, vitality, social function, emotional role, and mental health, and the scales of academic expectations of the outcome, academic progress goals, school satisfaction, and future expectations. Results: The results indicate the existence of high scores in physical function, physical role, and emotional role, except in social function. A correlation was observed between the physical health component and academic expectations, academic satisfaction, and future expectations. In turn, mental health is correlated with academic progress goals, academic expectations of the outcome, academic satisfaction, and expectations for the future. Conclusions: Young university students have a good quality of life, however, there is a proportion of students who do not adopt healthy habits and others do. Physical and mental health are important aspects in students; however, university students do not visualize the impact of these benefits on school success, the achievement of their academic expectations, progress goals, and even their future expectations.

Optimized Production of a Redox Metabolite (pyocyanin) by Pseudomonas aeruginosa NEJ01R Using a Maize By-Product.

Pseudomonas aeruginosa metabolizes pyocyanin, a redox molecule related to diverse biological activities. Culture conditions for the production of pyocyanin in a defined medium were optimized using a statistical design and response surface methodology. The obtained conditions were replicated using as substrate an alkaline residual liquid of cooked maize and its by-products. The untreated effluent (raw nejayote, RN) was processed to obtain a fraction without insoluble solids (clarified fraction, CL), then separated by a 30 kDa membrane where two fractions, namely, retentate (RE) and filtered (FI), were obtained. Optimal conditions in the defined medium were 29.6 °C, 223.7 rpm and pH = 6.92, which produced 2.21 µg mL-1 of pyocyanin, and by using the wastewater, it was possible to obtain 3.25 µg mL-1 of pyocyanin in the retentate fraction at 40 h. The retentate fraction presented the highest concentration of total solids related to the maximum concentration of pyocyanin (PYO) obtained. The pyocyanin redox behavior was analyzed using electrochemical techniques. In this way, valorization of lime-cooked maize wastewater (nejayote) used as a substrate was demonstrated in the production of a value-added compound, such as pyocyanin, a redox metabolite of Pseudomonas aeruginosa NEJ01R.

Oral lesions in patients with primary Sjögren's syndrome. A case-control cross-sectional study

BACKGROUND: To evaluate the presence of oral lesions in a group of patients with primary Sjögren's syndrome (pSS) and compare these results with a matched control group (CG). MATERIAL AND METHODS: An observational cross-sectional study was conducted. 61 pSS patients (60 women, 1 man, mean age 57.64 ± 13.52) diagnosed according to the American European Criteria (2002), and 122 matched control patients (120 women, 2 men, mean age 60.02 ± 13.13) were included. Demographic and medical data, oral lesions and salivary flow rate were collected. RESULTS: Compared with the controls, pSS patients were 3.95 more likely to have oral lesions (OR 3.95; 95% CI 2.06-7.58; p = 0.0001). 57.4% pSS patients presented oral lesions compared to 25.4% in CG. The most common were candidiasis (13.1% vs 2.5%), traumatic lesions (13.1% vs 4.1%), apthae (8.2% vs 0), and fissuration of the tongue (8.2% vs 0.8%). pSS patients with oral lesions had lower salivary flow levels (stimulated and unstimulated), although these differences were not significant. Significant associations were found between the presence of oral lesions and systemic manifestations and history of parotid gland enlargement in pSS patients. CONCLUSION: pSS patients suffer more oral lesions than general population and these lesions may aggravate the pSS disease

Calidad de vida en estudiantes universitarios con sobrepeso y obesidad: Diferencias por sexo / Quality of life in university students with overweight and obesity: Differences by sex

Introducción: El objetivo de este artículo es dar a conocer la relación entre la calidad de vida, el sobrepeso y la obesidad, así como comparar si existen diferencias significativas por sexo. Método: Se utilizó el cuestionario de salud SF-36v2, que mide la salud funcional y el bienestar a partir de ocho dimensiones: función física, rol físico, dolor corporal, salud general, vitalidad, función social, rol emocional y salud mental. El tipo de investigación es cuantitativa con un diseño prospectivo, transversal y observacional. Las técnicas estadísticas que se utilizaron para el análisis de la información fueron el coeficiente de correlación de Pearson y la prueba t para muestras independientes. Para la magnitud del efecto se utilizó la d de Cohen. La muestra se seleccionó a partir del muestreo no probabilístico por conveniencia; el total de participantes fue de 320. Resultados: Se encontraron diferencias estadísticas significativas en dos de las dimensiones, con un tamaño del efecto pequeño, menor a una desviación estándar. Conclusión: Las mujeres sienten más energía y vitalidad que los hombres, éstos algunas veces se ven más afectados por los problemas de salud física o emocional que interfieren en su vida social.

Introduction: The objective of this article is to show the relation between the quality of life, overweight and obesity, and to compare if there are significant differences by gender. Methodology: The SF-36v2 questionnaire was used to measure the functional health and wellness from eight dimensions: physical function, physical role, body pain, general health, vitality, social function, emotional role and mental health. The study is quantitative with a traversal, observational and prospective design. The statistical techniques that were used to the data analysis was the Pearson relation coefficient and the t test to independent samples. The d of Cohen was used to obtain the magnitude of the effect. The sample was selected from a non-probabilistic sample by convenience; the total of participants was of 320. Results: Significant statistic differences were found in two of the dimensions, with a small magnitude of the effect, less than a standard deviation. Conclusion: Women feel more energy and vitality than men, whom sometimes are more affected by the physical or emotional health problems that interfere in their social life.

Alveolar hemorrhage associated with cocaine consumption.

Cocaine is an illegal drug; its abuse and toxicity are a public health problem due to its high morbidity and mortality. Cocaine can affect the cardiovascular, central nervous and respiratory systems. The case of a 42-year-old male without history of chronic or degenerative diseases, but previous cocaine consumption is presented in this report. The patient is admitted to the Emergency Department given that the clinical presentation included hemoptysis and dyspnea with mild to minimal activity, which evolved to orthopnea. Advanced airway management was required and supportive care at the Intensive Care Unit was provided. Imaging studies showed evidence compatible with alveolar hemorrhage diagnosis. In search of an autoimmune etiology, an antibody-screening panel was requested, reporting negative results for autoimmune disorders. The patient management was based on corticosteroid therapy and plasmapheresis to counter the persistent hemoptysis and hemoglobin serum level decline. The management strategy was based on the clinical suspicion of vasculitis and a torpid clinical evolution. Pulmonary sepsis ensued, resulting in patient's death. The necropsy report describes the primary cause of death as diffuse alveolar hemorrhage secondary to diffuse alveolar injury. This case report presents the detailed clinical, imagining and histopathological findings of a patient with alveolar hemorrhage secondary to cocaine consumption, as well as a review of the literature.
