ABSTRACT
Objetivo: Caracterizar indicadores clínicos, comorbilidad y variables de laboratorio asociadas a la hospitalización y mortalidad de personas mayores con Covid-19. Materiales y métodos: Se realizó una revisión sistemática de acuerdo con la declaración PRISMA, en las bases de datos Medline/Pubmed, Science Direct y WOS, en la que se aplicaron estrategias de búsquedas específicas para artículos y estudios que fueron publicados desde el periodo de tiempo comprendido entre el 1 de enero de 2020 hasta el 26 de noviembre de 2020. Resultados: Se identificaron 28 artículos que cumplieron con los criterios de selección, con una suma del tamaño muestral de los estudios incluidos de 581 319 sujetos (55.1 % mujeres). De los factores analizados, un estado funcional óptimo, el sexo femenino, el recuento de linfocitos, el uso de anticoagulantes de manera curativa y los niveles de albúmina sérica, se han asociado a un mejor pronóstico clínico en adultos mayores de 65 años. Conclusiones: Se encontraron características clínicas, de comorbilidad y variables de laboratorio asociadas a la hospitalización y morbilidad.
Objective: To characterize clinical indicators, comorbidity and laboratory variables associated with hospitalization and mortality in older people with Covid-19. Materials and methods: A systematic review was carried out in accordance with the PRISMA statement, in the Medline/Pubmed, Science databases. Direct and WOS, in which specific search strategies were applied to articles and studies that were published from the period of time between January 1, 2020 and November 26, 2020. Results: 28 articles were identified that met the the selection criteria, with a sum of the sample size of the included studies of 581,319 subjects (55.1% women). Of the factors analyzed, optimal functional status, female gender, lymphocyte count, curative use of anticoagulants, and serum albumin levels have been associated with a better clinical prognosis in adults older than 65 years. Conclusions: Clinical characteristics, comorbidity and laboratory variables associated with hospitalization and morbidity were found.
ABSTRACT
Objetivo: determinar la existencia de una asociación entre el índice de masa corporal y la regulación cardiovascular en estudiantes de medicina. Materiales y métodos: estudio transversal con un diseño aleatorio. La muestra se compuso por 54 estudiantes de medicina (21,2 ± 1,6 años) evaluados y clasificados según el índice de masa corporal: normopeso (NP; IMC < 25 kg/m2); sobrepeso (SP; IMC≥ 25 kg/m2); obesos (OB; IMC ≥ a 30 Kg/m2). Las medidas antropométricas, presión arterial y variabilidad de frecuencia cardiaca (HRV) fueron las variables evaluadas. Resultados: el 51,9% de los estudiantes presenta sobrepeso u obesidad. El índice de masa corporal correlaciona negativamente con el parámetro de variabilidad de frecuencia cardíaca, especialmente al compararla en los dominios de tiempo de HRV (p<0,001). También se observaron diferencias en el control autonómico cardíaco al comparar los grupos de estudio en LnRMSSD (p<0,01) y LnSDNN (p<0,01). Conclusión: la implementación de medidas que disminuyan los valores de IMC posibilitará un mayor control autonómico cardíaco y mejor salud cardiovascular en estudiantes de medicina..(Au)
Objective: this study had the purpose of knowing the association of the body mass index and cardiovascular regulation of medical students. Materials and methods: a cross-sectional study with a randomized design. The sample consisted of 54 medical students (21,2 ± 1,6 years) who were evaluated and classified according to the body mass index: Normal weight (NP; BMI <25 kg / m2); Overweight (SP; BMI≥ 25 kg / m2); Obese (OB; BMI ≥ 30 Kg / m2). Anthropometric measurements, blood pressure, and heart rate variability (HRV) were the variables evaluated. Results: 51,9% of the students are overweight or obese. The body mass index was negatively correlated with the heart rate variability parameter, especially when compared with the HRV time domains (p <0.001). Differences were also observed in cardiac autonomic control when comparing the study groups in LnRMSSD (p <0,01) and LnSDNN (p <0,01). Conclusion: the implementation of measures that decrease BMI values will allow greater autonomic cardiac control and better cardiovascular health in medical students..(Au)
ABSTRACT
Background: There is no evidence for the association of depressive symptoms with the sense of well-being of undergraduate medical students residing in high southern latitudes (HSL). Aim: To assess the frequency of depressive symptoms and its relationship with seasonal sensitivity and quality of life in medical students residing in HSL. Material and Methods: The Beck anxiety and depressive symptoms inventory, the seasonal pattern assessment questionnaire and the quality-of-life questionnaire of the WHO were applied to 102 medical students residing in Magallanes, Chile. Results: Fifty-two percent of respondents reported some degree of depressive symptoms. These symptoms were significantly associated with the seasonal pattern score (r = 0.432, p < 0.01). They were also inversely associated with parameters of physical health and psychosocial health (r = −0.567, p < 0.01 and r = −0.708, p < 0.01, respectively). There was also a correlation between depressive and anxiety symptoms. Conclusions: Depressive symptoms are common in medical students residing in HSL and they are associated with seasonal sensitivity and quality of life measures.
