Risk factors for hospitalization and mortality due to dengue fever in a Mexican population: a retrospective cohort study.

OBJECTIVES: Identify risk factors associated with increased hospital admission and mortality due to dengue fever (DF), and estimate the risk magnitude associated with each individual variable. METHODS: Records of patients diagnosed with dengue were obtained from the Mexican National Epidemiological Surveillance System. Descriptive statistics were performed in all variables. Demographic characteristics and comorbidities were compared between patients based on type of care and mortality. Multivariable analysis was done with a logistic regression model, using two different outcomes: hospitalization and mortality. RESULTS: A total of 24,495 patients were included in the analysis, with a DF case fatality rate of 0.58%. Patients younger than 10 and older than 60, were found to have a greater risk of both hospitalization and mortality due to DF. Comorbidities associated with a higher risk for hospital admission include cirrhosis, CKD, immunosuppression, diabetes, and hypertension. For mortality, CKD, diabetes, and hypertension were identified as risk factors, along with pregnancy. CONCLUSION: Identification of risk factors associated with increased hospitalization and mortality due to DF can help categorize patients that require close monitoring and inpatient care. Early identification of warning signs and patients at increased risk is key to avoiding delay of supportive care.

Lessons from the COVID-19 pandemic: knowledge and preventive actions among a mexican population sample / Lecciones de la pandemia de COVID-19: conocimiento y acciones preventivas de una muestra de población mexicana

Objective: to evaluate the knowledge of the general population about the COVID-19 pandemic, including the disease and the preventive measures to reduce spreading of the virus undertaken by participants. Materials and methods: a cross-sectional study on a Mexican population sample was conducted during the period of March 20th to March 27th in Mexico, via a computer-based survey. General knowledge about COVID-19 and the adherence to recommendations were evaluated. Results: a total of 2,577 participants completed the survey. The results revealed an overall proper knowledge about the disease, with 76.2% having the proper knowledge about the disease, which was significantly correlated with age (r=0.15, p<0.001), socioeconomic status (r=0.06, p<0.003) and maximum academic level achieved by the study subjects (r=0.12, p<0.001). Conclusions: overall, people have good knowledge of COVID-19 and know about the specific public health recommendations, but a large proportion of people do not strictly follow these recommendations..Au

Objetivo: evaluar el conocimiento de la población general acerca de la pandemia de COVID-19, incluyendo datos sobre la enfermedad y las medidas preventivas para reducir la propagación del virus. Materiales y métodos: se realizó un estudio transversal en una muestra de la población mexicana durante el periodo del 20 al 27 de marzo del 2020 por medio de una encuesta electrónica. Se evaluó el conocimiento general sobre COVID-19 y el apego a las recomendaciones de salud pública Resultados: 2,577 participantes completaron la encuesta. Los resultados muestran un adecuado conocimiento sobre la enfermedad en la población general (76.2% de la muestra), el cual está levemente correlacionado con la edad (r=0.15, p<0.001), estado socioeconómico (r=0.06, p<0.003) y grado académico (r=0.12, p<0.001). Conclusiones: en general, la población conoce la información acerca del COVID-19 y conoce las recomendaciones de salud pública, pero una gran proporción de la gente no sigue estrictamente estas recomendaciones..Au

Brain-Derived Neurotrophic Factor and Its Associations with Metabolism and Physical Activity in a Latino Sample.

BACKGROUND: Brain-derived neurotrophic factor (BDNF) is associated with body weight and other health conditions but remains understudied in the Latino population. The aim of this study was to examine the associations of BDNF serum levels with body mass index (BMI), physical activity, and the rs6265 nonconservative polymorphism among 349 Latinos aged ≥18 years enrolled in the Arizona Insulin Resistance Registry. MATERIALS AND METHODS: Data on physical activity were acquired using a self-reported questionnaire. BDNF serum levels were measured utilizing a modified ELISA method, and the rs6265 polymorphism was genotyped by the Assay-by-Design service. Two sample t-tests or chi-squared tests were employed to compare demographics and outcomes between physically active and nonactive groups as well as between rs6265 CC and CT+TT groups. RESULTS: BDNF levels and rs6265 polymorphism did not differ significantly between the physically active (N = 195) and nonactive group (N = 154). Participants with the rs6265 polymorphism did not show any significant difference in BDNF levels or BMI when compared with those with the normal functional variant. Higher BDNF levels were significantly associated with higher age (r = 0.11, P = 0.04) and higher 2-hr glucose level (r = 0.11, P = 0.04). CONCLUSIONS: In this cross-sectional study, the rs6265 polymorphism was not associated with a higher risk of obesity, or lower circulating levels of BDNF. Thus, the rs6265 polymorphism may have a different impact in Latinos as compared with other previously studied populations.

Conocimiento sobre la diabetes mellitus tipo 2 en estudiantes universitarios: un estudio transversal y observacional en la Universidad Anáhuac México Campus Norte en la Ciudad de México: un estudio para evaluar el conocimiento en alumnos universitarios / Knowledge about type 2 Diabetes Mellitus in universitary students: a transversal and observational study in Anahuac University Mexico North Campus in Mexico City: a study to evaluate the knowledge of the disease in university students

Objective: To assess the lack of knowledge about Type 2 Diabetes Mellitus in the student population of Anahuac University Mexico North Campus (UAMN). Materials and Methods: An observational, transversal study was conducted from February to April 2017. A 19-question survey based on the study by Al-Sararyra and colleagues in Jordan was applied to 300 students aged 18-25. Results: The lack of knowledge about the disease was made evident, especially its signs, symptoms and complications. The majority of students knew the risk factors of the disease. Information about the disease was obtained by the students mostly through family members or school education. Conclusion: The study shows a lack of knowledge in a high education institution about one of the most important diseases in the country. An educational intervention is necessary to increase their knowledge of the disease for students to take part in preventive measures.

Objetivo: Evaluar la falta de conocimiento sobre la Diabetes Mellitus tipo 2 en una población estudiantil de alto nivel de la Universidad Anáhuac México Campus Norte (UAMN). Material y Métodos: Estudio transversal y observacional, realizado de febrero a abril de 2017. Se realizaron encuestas de 19 preguntas a 300 alumnos de 18 a 25 años, basada en el trabajo de Al-Sarayra y colaboradores en la Universidad Al-Balqa en Jordania. Resultados: Se evidenció la falta de conocimiento sobre la enfermedad, especialmente sobre signos, síntomas y complicaciones. Los mayoría de los alumnos conocía los factores predisponentes. La educación escolar y los familiares fueron las principales fuentes de información para la enfermedad. Conclusión: Se refleja la carencia de conocimiento, entre alumnos con educación básica completa y aspirando a licenciaturas, sobre una de las enfermedades más importantes a nivel internacional. Una intervención educativa es necesaria para que tengan más información sobre la enfermedad y así tomen las medidas preventivas necesarias.
